[0001] This application claims the benefit of U.S. Provisional
Application No. 60/853,375 filed Oct. 20, 2006, the contents of
which are incorporated herein by reference.
FIELD OF THE INVENTION
[0002] The present invention relates generally to the field of
exercise devices, and more particularly relates to an exercise
device including features for simultaneously working out the upper
and lower body.
BACKGROUND OF THE INVENTION
[0003] Various types and configurations of exercise devices have
been developed to provide the user with an aerobic workout. Such
devices include, for example, treadmills, stepping machines,
cycling devices, rowing devices, etc. However, an exercise device
has not been developed which includes a base unit having a support
surface in which discrete portions or regions of the support
surface light up to elicit a response or activity (i.e., walking,
running, jumping, etc.) to provide a workout of the lower body, and
which further includes features that simultaneously provide a
workout of the upper body. Additionally, an exercise device has not
been developed which provides a realistic simulation of the
activity of jumping rope to provide a workout of the lower body,
and which further includes features that simultaneously provide a
workout of the upper body. Furthermore, an exercise device has not
been developed for use in association with activities involving
walking, running or jumping to provide a workout of the lower body
while providing feedback via a number of position sensors to verify
the user's performance of such activities, and which further
includes features that simultaneously provide a workout of the
upper body.
[0004] Thus, there is a general need in the industry to provide an
improved exercise device including features for simultaneously
working out the upper and lower body. The present invention meets
this need and provides other benefits and advantages in a novel and
non-obvious manner.

DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
[0024] For the purposes of promoting an understanding of the
principles of the invention, reference will now be made to the
embodiments illustrated in the drawings and specific language will
be used to describe the same. It will nevertheless be understood
that no limitation of the scope of the invention is hereby
intended, such alterations and further modifications in the
illustrated devices, and such further applications of the
principles of the invention as illustrated herein being
contemplated as would normally occur to one skilled in the art to
which the invention relates.
[0025] Referring to FIG. 1, shown therein is an exercise device 20
according to one form of the present invention. As will be
discussed in greater detail below, the exercise device 20 may be
used in association with multiple activities, and is particularly
used in association with activities involving jumping, walking or
running. For example, in one embodiment of the invention, the
exercise device 20 is used to simulate the activity of jumping
rope. In another embodiment of the invention, the exercise device
20 is used in association with walking or running in place. In a
further embodiment of the invention, the exercise device 20 is used
to measure vertical jumping ability and various parameters
associated therewith. However, it should be understood that other
embodiments of the invention are also contemplated, and that the
exercise device 20 may be used in association with activities other
than those specifically illustrated and described herein.
[0026] In the illustrated embodiment of the invention, the exercise
device 20 is generally comprised of a base unit 22, an adjustable
position sensor assembly 24, an adjustment mechanism 26, and a
control panel 28 including a monitor or display 30. The function of
each of these components of the exercise device 20 will now be
summarized, followed by a more in-depth discussion regarding the
structural configuration and function of each of the
components.
[0027] The base unit 22 includes a number of light sources or
indicators that serve to provide a visual signal or cue to elicit a
predetermined response from the user. In one embodiment, the
elicited response is a jumping action. However, other elicited
responses are also contemplated as falling within the scope of the
invention, such as a walking action, a running action, a skipping
action, or any other action associated with an exercise activity
that would occur to one of skill in the art. The base unit 22 may
also be equipped with a number of sensor elements that serve to
determine the user's presence upon or absence from the base unit
22.
[0028] The adjustable position sensor assembly 24 includes a number
of sensor elements that serve to determine whether or not the
user's response satisfies a predetermined objective or goal, such
as, for example, a predetermined elevation and/or an elapsed period
of time. The adjustment mechanism 26 functions to vary the
elevation or vertical position of the position sensor assembly 24
relative to the base unit 22 to correspondingly change the
predetermined objective or goal of the user.
[0029] The control panel 28 controls and monitors operation of the
various electrical components associated with the exercise device
20 and may be configured to provide visual and/or audible
indications or cues to elicit a user response. The display 30 may
also be configured to provide visual indications or cues to elicit
a user response, and also serves to provide direct visualization of
various parameters that are indicative of the user's performance of
a predetermined activity as well as other types of information or
data that may be useful to the user.
[0030] According to one embodiment of the invention, the base unit
22 is generally comprised of a support frame 100, a light source
assembly 102, an upper mat or support pad 104, a support plate 106,
and a pressure sensitive pad or strip 108. The components of the
base unit 22 are preferably interconnected in such a manner as to
form an integral base unit assembly. Additionally, the footprint of
the base unit 22 is preferably sized as small as possible while
still allowing for unrestrained/uninhibited movement of the user
during performance of an exercise activity. Each of the components
of the base unit 22 will now be discussed in greater detail.
[0031] In one embodiment of the invention, the support frame 100 is
formed of a number of support members 120a-120d that are
interconnected to form a substantially rigid framework for
providing structural support and rigidity to the base unit 22. In
the illustrated embodiment, the support frame 100 includes a pair
of side support members 120a, 120b and front and rear support
members 120c, 120d extending between the side support members 120a,
120b. The support frame 100 may also include a number of
intermediate support members extending between the side support
members 120a, 120b and/or the front and rear support members 120c,
120d to provide further structural support and rigidity to the base
unit 22. In one embodiment of the invention, the support members
120a-120d are comprised of structural tubing formed of a
lightweight material, such as, for example, a metallic material
including aluminum or steel, a plastic or polymeric material, a
composite material, or any other material that would occur to one
of skill in the art. However, it should be understood that other
types and configurations of support members and support structures
are also contemplated as falling within the scope of the present
invention. In a further embodiment of the invention, the base unit
22 may include a number of levelers (not shown) attached to the
underside of the support frame 100 to provide a means for leveling
the base unit 22, particularly when the base unit 22 is placed on
an uneven surface.
[0032] In one embodiment of the invention, the light source
assembly 102 is generally comprised of a pair mounting rails 130a,
130b and a plurality of light sources 132. The mounting rails 130a,
130b are positioned along the sides of the base unit 22, extending
generally along the longitudinal axis L and secured to the side
support frame members 120a, 120b, respectively. The light sources
132 are mounted to each of the mounting rails 130a, 130b and are
disposed at intermittent locations along the longitudinal axis L.
As will discussed in greater detail below, the light sources 132
are capable of illuminating discrete portions or bands of the base
unit 22, and more particularly the upper support pad 104, to elicit
a predetermined response from the user. It should be understood,
however, that the light sources may be adapted to provide other
types and configurations of illuminated areas or regions of the
base unit 22.
[0033] Each of the mounting rails 130a, 130b is configured
substantially identical to one another. Accordingly, only the
mounting rail 130a will be described in detail, it being understood
that the mounting rails 130b is configured substantially identical
to mounting rail 130a. Referring specifically to FIG. 6, according
to one embodiment of the invention, the mounting rail 130a includes
a base portion 134 secured to the upper surface of the support
frame member 120a, a leg portion 136 extending upwardly from the
base portion 134, and a housing portion 138 positioned adjacent the
end of the leg portion 136. The housing portion 138 defines a
hollow interior region 140. A number of light source openings or
apertures 142 are formed through a side wall of the housing portion
138 facing the inner area of the base unit 22. A pair of removable
end caps or covers 144a, 144b (FIGS. 1 and 2) are preferably
secured to opposite ends of each support rail 130a, 130b by a
number of fasteners 146 (FIG. 2) to close off the ends of the
support rails 130a, 130b, and more particularly the interior
regions 140 of the housing portions 138.
[0034] In one embodiment of the invention, the light sources 132
are comprised of candescent or incandescent lights, with each light
having a base portion 150 and an illumination or bulb portion 152.
However, it should be understood that other types and
configurations of light sources 132 are also contemplated as
falling within the scope of the present invention, such as, for
example, a fiber-optic light source, a fluorescent light source, a
laser light source, an LED light source, an infrared light source,
or any other type of light source that would occur to one of skill
in the art. It should be appreciated that any light source that is
capable of generating a visual indication, signal or cue to elicit
a response from the user is contemplated for use in association
with the present invention. It should further be appreciated that
the light source may additionally be configured to provide
non-visual indications, signals or cues to elicit a response from
the user. It should also be understood that although the light
sources 132 are illustrated and described as having a bulbous
configuration, other configurations are also contemplated, such as,
for example, a tubular configuration or filament configuration
extending laterally across the base unit 22.
[0035] As most clearly shown in FIG. 6, the base portions 150 of
the light sources 132 are positioned within the interior region 140
of the housing 138, with the bulb portions 152 extending through
respective ones of the light source apertures 142. In one
embodiment of the invention, the lights 132 associated with the
mounting rails 130a, 130b are arranged in opposing pairs that are
generally aligned across from one another. The base portions 150 of
the lights 132 are secured to a mounting bracket 154 which is in
turn engaged within the interior region 140 of the housing 138 to
securely mount the lights 132 to the support rail 130a. Electrical
leads 156 extend from each of the lights 132 and run through the
interior region 140 of the housing 138 toward the front of the base
unit 22. The leads 156 may be routed through laterally-extending
tubular members 158a, 158b arranged at the front ends of the
support rails 130a, 130b and up through the interior region of a
vertical support column 160 to the control panel 28 (see FIG. 2).
The control panel 28 functions to turn the lights 132 on and off at
select time intervals, the details of which will be discussed
below.
[0036] In one embodiment of the invention, the vertical support
column 160 is generally comprised of a pair of side walls 162a,
162b and a front wall 163 defining a hollow interior region 164. A
removable rear cover (not shown) may also be provided to enclose
the interior region 164 and the working components of the
adjustment mechanism 26. The vertical support column 160 is
pivotally mounted to the base unit 22 via a pivot pin 165 passing
between a pair of opposing yoke plates 166a, 166b (FIG. 5)
extending upwardly from the laterally-extending tubular members
158a, 158b. In this manner, the vertical support column 160 is
permitted to pivot about a pivot axis P.sub.1 between a
substantially vertical operational position (FIG. 1) and a
substantially horizontal storage or transport position (FIG.
10).
[0037] The vertical support column 160 is selectively maintained in
the vertical operational position via a bracket 167 having a flange
plate portion 168a secured to the lower ends of the column side
walls 162a, 162b and a base plate portion 168b that is selectively
attached to the front frame support member 120c via a number of
fasteners 169 (FIG. 2). However, other means for selectively
maintaining the vertical column 160 in the vertical operational
position are also contemplated as falling within the scope of the
present invention. As should be appreciated, pivoting the support
column 160 to the collapsed configuration illustrated in FIG. 10
provides for a more compact, lower profile configuration to
facilitate transport of the exercise device 20 and/or storage of
the exercise device 20 in areas having limited space, such as, for
example, under a bed or in a closet.
[0038] In one embodiment of the invention, the upper support pad
104 defines an upper support surface 105 and is preferably formed
of a resilient, shock-absorbing material that is strong enough to
support the dynamic weight of the user during an activity such as
jumping, running, walking, etc., while still providing a certain
degree of give or flexible resilience to reduce the likelihood of a
stress-related injury. Although the support pad 104 and the upper
support surface 105 have been illustrated and described as having a
generally flat, planar configuration, it should be understood that
other configurations are also contemplated, including curved or
angled configurations. The support pad 104 may be formed of a
non-slip material to reduce the likelihood of user injury.
Alternatively, the upper support surface 105 of the support pad 104
may be treated to provide a non-slip surface, such as, for example,
by roughening the upper support surface 105 and/or by applying a
non-slip material or coating to the upper support surface 105. In a
preferred embodiment of the invention, the support pad 104 is
formed of a transparent, translucent, semi-translucent or
semi-opaque material that is capable of allowing for the
transmission of an amount of light therethrough, the purpose of
which will become apparent below. In a specific embodiment of the
invention, the upper pad 104 is formed of a urethane material.
However, other materials are also contemplated for use in
association with the present invention, including various types of
plastic materials, polymeric materials, or rubber materials.
[0039] As illustrated in FIGS. 5-7, a number of channels or
openings 170 are formed through the support pad 104, extending
laterally across the base unit 22. The support pad 104 also
includes a pair of mounting flange portions 172a, 172b extending
laterally from opposite sides of the support pad 104 and running
substantially the entire length thereof, the purpose of which will
be discussed below. In one embodiment of the invention, the
channels 170 have a substantially circular cross section and are
generally aligned with opposing pairs of the lights 132 such that
activation of an opposing pair of the lights 132 will illuminate
the region of the support pad 104 adjacent the corresponding light
channel 170. The light channels 170 are preferably sized and
positioned such that the thickness of material t.sub.1 (FIG. 6)
directly above the light channels 170 is significantly less than
the thickness of material t.sub.2 (FIG. 7) between adjacent ones of
the light channels 170. In this manner, a majority of the light
emitted by the lights 132 will be transmitted in an upward
direction to illuminate the region of the support pad 104 above the
corresponding light channel 170. Although a specific size, shape
and configuration of the light channels 170 has been illustrated
and described herein, it should be understood that other sizes,
shapes and configurations of the light channels 170 are also
contemplated as falling within the scope of the present
invention.
[0040] In the illustrated embodiment of the invention, the light
channels or lights bands 170 extend laterally across the base unit
22 and are generally aligned with the transverse axis T. However,
it should be understood that in other embodiments of the invention,
the light channels 170 may alternatively extend along the
longitudinal axis L or in directions oblique to the transverse axis
T. Furthermore, although the light channels 170 are illustrated as
having a substantially linear configuration, it should be
understood that in other embodiments of the invention, some or all
of the light channels 170 may take on a non-linear configuration,
such as, for example, an arcuate or curved configuration or a
polygonal configuration. One such embodiment is illustrated in FIG.
8 wherein the light channels 170' positioned toward the front and
rear of the base unit 22 have varying degrees of lateral curvature,
the purpose of which will be discussed below. Additionally,
although the light channels 170 are illustrated as being offset
from one another by a substantially uniform distance, it should be
understood that in other embodiments of the invention, the distance
between the light channels 170 may be varied. Moreover, although
the base unit 22 is illustrated as having eight (8) light channels
170, it should be understood that any number of light channels 170
may be used, including a single light channel 170.
[0041] In one embodiment of the invention, the support plate 106 is
formed of a relatively rigid material, such as, for example, an
aluminum material or a composite material. However, it should be
understood that the support plate 106 may be formed of other
materials as would occur to one of skill in the art, such as, for
example, a plastic material or a polymeric material. The support
plate 106 is positioned beneath the support pad 104 and is coupled
thereto by a number of clip members 180 that extend about the
lateral end portions of the support plate 106 and engage the
mounting flange portions 172a, 172b of the support pad 104. The
clip members 180 are in turn secured to the base portions 134 of
the mounting rails 130a, 130b to engage the support pad 104 and the
support plate 106 to the support frame 100.
[0042] In one embodiment of the invention, the pressure sensitive
pad or strip 108 is formed of a relatively rigid material, such as,
for example, an aluminum material or a composite material. However,
the pressure sensitive pad 108 (FIGS. 5 and 6) may also be formed
of other materials as would occur to one of skill in the art, such
as, for example, a plastic material or a polymeric material.
[0043] Referring to FIGS. 5 and 6, the pressure sensitive pad or
strip 108 is positioned beneath the support plate 106 and is
engaged to the support frame 100. A plurality of pressure sensors
190 are positioned along the upper surface of the pressure
sensitive pad or strip 108 proximately adjacent the lower surface
of support plate 106. A number of pressure sensors 190 may also be
positioned between the support plate 106 and the base portion 134
of the mounting rails 130a, 130b and/or at other locations along
the support plate 106. The pressure sensors 190 are electrically
connected to the control panel 28. As should be appreciated, when
the user stands upon the support pad 104, the weight of the user
will slightly displace the support plate 106, thereby actuating one
or more of the pressure sensor 190. The pressure sensors 190 in
turn provide a signal to the control panel 28 to indicate the
presence or absence of the user upon the support pad 104. Although
a specific type and configuration of the pressure sensor 190 has
been illustrated and described herein, it should be understood that
other types and configurations of pressure sensors are also
contemplated for use in association with the present invention as
would occur to one of skill in the art.
[0044] According to one embodiment of the invention, the adjustable
position sensor assembly 24 is generally comprised of a mounting
structure 200 and a plurality of position sensors 202 mounted to
the mounting structure 200. As illustrated in FIG. 4, the position
sensors 202 are preferably arranged along a sensing plane S located
above the upper surface 105 of the support pad 104 so as to detect
the presence of the user along the sensing plane S. In a preferred
embodiment of the invention, the sensing plane S is arranged
substantially parallel with the upper surface 105 of the support
pad 104. However, it should be understood that the sensing plane S
may be arranged at an oblique angle relative to the support surface
105. Additionally, although the sensing plane S has been
illustrated and described as having a generally flat or linear
configuration, it should be understood that the sensing plane S may
take on other configurations, such as, for example, a polygonal
configuration or an arcuate or rounded configuration.
[0045] In the illustrated embodiment of the invention, the position
sensor assembly 24 is comprised of a plurality of position sensors
202 positioned to define a single sensing plane S located above the
upper surface 105 of the support pad 104 so as to detect the
presence of the user along the sensing plane S. However, it should
be understood that in other embodiments of the invention, the
position sensor assembly 24 may include a plurality of position
sensors 202 arranged so as to define multiple sensing planes S
positioned at predetermined vertical intervals relative to one
another. In this manner, the vertical adjustability feature of the
position sensor assembly 24 may be eliminated if desired, relying
instead upon the sensing of the presence and/or absence of the user
along the multiple sensing planes S to correspondingly measure the
vertical position of the user relative to the upper surface 105 of
the support pad 104. In a further embodiment of the invention, the
position sensor assembly 24 may include a plurality of position
sensors 202 arranged so as to define one or more sensing planes S
extending in a substantially vertical orientation to measure the
position of the user relative to the upper surface 105 of the
support pad 104.
[0046] In one embodiment of the invention, the mounting structure
200 includes a pair of mounting arms or bars 204a, 204b disposed
along respective sides of the base unit 22. The mounting arms 204a,
204b preferably extend generally along the longitudinal axis L and
are preferably positioned generally above the light source mounting
rails 130a, 130b. However, other orientations and positions of the
mounting arms 204a, 204b are also contemplated as falling within
the scope of the present invention. The mounting arms 204a, 204b
are interconnected to one another via a generally V-shaped or
U-shaped base portion 206 which is in turn coupled to the vertical
support column 160, the details of which will be discussed below.
The position sensors 202 are mounted to and are disposed at
intermittent axial locations along the mounting arms 204a,
204b.
[0047] The mounting arms 204a, 204b are configured substantially
identical to one another. Referring to FIGS. 5 and 6, in one
embodiment of the invention, the mounting arms 204a, 204b have a
tubular configuration defining a hollow interior region 210. A
number of sensor openings or apertures 212 (FIG. 6) are formed
through a side wall of each of the mounting arms 204a, 204b facing
the inner area of the base unit 22. A removable end cap or cover
214 (FIG. 1) is preferably positioned over the open end of each
mounting arm 204a, 204b to close off the interior region 210 from
the outer environment.
[0048] In one embodiment of the invention, the position sensors 202
are of the photoelectric type, with each position sensor 202
including an emitter unit E and a receiver unit R. As shown in
FIGS. 5 and 6, the emitter and receiver units E, R are positioned
within the interior regions 210 of the mounting arms 204a, 204b,
with the emitting and receiving portions 214 of the units E, R
generally aligned with respective ones of the sensor apertures 212.
The base portions 215 of the units E, R are secured to a mounting
bracket 216 which is in turn engaged within the interior region 210
of the mounting arms 204a, 204b to securely mount the sensors 202
to the mounting structure 200. Electrical leads 218 extend from
each of the emitter and receiver units E, R and are run through the
interior regions 210 of the mounting arms 204a, 204b, through the
interior region of the base portion 206, and up along the vertical
support column 160 to the control panel 28.
[0049] As should be appreciated, the emitter units E each emit a
light beam B that is received or sensed by a corresponding receiver
unit R, with each of the light beams B extending generally along
the sensing plane S. As should also be appreciated, the emitter and
receiver units E, R are arranged in opposing pairs, with an emitter
unit E mounted to one of the mounting arms (e.g., 204a) and
positioned in generally alignment with a corresponding receiver
unit R mounted to the opposite mounting arm (e.g., 204b). When
there is no obstruction present between the emitter unit E and the
receiver unit R, the light beam B will remain unbroken and the
receiver unit R will communicate a signal to the control panel 28
indicating an uninterrupted condition. However, when the light beam
B is broken by an obstruction (e.g., by the user's foot or leg) the
receiver unit R will communicate a signal to the control panel 28
indicating an interrupted condition. Accordingly, the position
sensors 202 are capable of detecting the presence or absence of the
user along the sensing plane S, and hence the position of the user
relative to the base unit 22.
[0050] As will be discussed below, the height h.sub.1 or elevation
of the sensor assembly 24 and the position sensors 202 may be
varied relative to the support surface 105 of the support pad 104
(FIG. 4) via the adjusting mechanism 26 to correspondingly adjust
the height of the sensing plane S relative to the upper support
surface 105. The adjustment mechanism 26 is preferably configured
to provide approximately thirty-six (36) inches of vertical
adjustment to the sensor assembly 24. In one embodiment of the
invention, the light beams B are visible to provide the user with a
visual indication as to the selected height h.sub.1 of the position
sensors 202 and the sensing plane S. Laser-type emitters E that
emit a relatively intense/bright beam of light B are particularly
suitable for visualization by the user; however, other types of
emitters E are also contemplated as would occur to one of skill in
the art. In order to provide enhanced visualization of the light
beams B, the ambient lighting may be turned down and/or fog, smoke
or another type of air-borne substance or material may be provided.
Additionally, although the light beams B are illustrated as being
linear, it should be understood that in other embodiments of the
invention, the sensors 202 may be configured and arranged such that
the light beams B are non-linear (e.g., curvilinear or angled).
[0051] In one embodiment of the invention, the number of position
sensors 202 associated with the sensor assembly 24 corresponds to
the number of the light channels 170 in the base unit 22. In the
illustrated embodiment, the sensor assembly 24 includes eight (8)
position sensors 202 corresponding to the eight (8) light channels
170 in the base unit 22. However, it should be understood that any
number of position sensors 202 may be used, including a single
position sensor 202, a pair of position sensors 202, or any other
number of position sensors 202. It should also be understood that
the number of position sensors 202 need not necessarily correspond
to the number of light channels 170. Additionally, the position
sensors 202 need not necessarily be aligned directly above a
corresponding light channel 170, and need not necessarily be offset
from one another by a uniform distance.
[0052] As illustrated in FIG. 3, the opposing pairs of the emitter
and receiver units E, R are preferably arranged in a staggered or
alternating configuration such that the receiver units R are
separated from another by an intermediate emitter unit E. As a
result, the likelihood that a receiver unit R will erroneously
detect the light beam B emitted from the wrong emitter unit E is
reduced. However, it should be understood that other configurations
are also contemplated, including configurations where all of the
emitter units E are mounted to one of the mounting arms (e.g.,
204a) and all the receiver units R are mounted to the opposite
mounting arm (e.g., 204b).
[0053] Although the position sensors 202 have been illustrated and
described as photoelectric-type sensors, with each position sensor
202 including an emitter unit E and a receiver unit R, it should be
understood that other types and configurations of position sensors
are also contemplate as falling within the scope of the present
invention. For example, instead of having separate emitter and
receiver units E and R, in other embodiments of the invention, the
emitter and receiver elements may be integrated into a single unit.
In this alternative embodiment, the integrated emitter/receiver
unit would be mounted to one of the mounting arms (e.g., 204a),
with an optical reflector mounted to the other mounting arm (e.g.,
204b) and positioned in generally alignment with the integrated
emitter/receiver unit. As should be appreciated, the emitter
portion of the integrated unit would emit a light beam that is
reflected off of the optical reflector and back to the receiver
portion of the integrated unit. Additionally, in lieu of
photoelectric-type sensors, the sensor assembly 24 may include
other types of position sensors, including various types and
configurations of laser sensors, fiber optic sensors, optical
sensors, motion sensors, infrared sensors, thermal sensors,
ultrasonic sensors, capacitive sensors, proximity sensors, or any
other type of position sensor that would occur to one of skill in
the art.
[0054] Referring to FIG. 9, according to one embodiment of the
invention, the adjustment mechanism 26 is generally comprised of an
actuator or electric drive motor 300, a threaded drive shaft or
screw 302, and a threaded drive plate or nut 304 that is coupled to
the sensor assembly 24 via a connector bracket 306. The drive motor
300 is electrically connected to the control panel 28. As should be
appreciated, rotation of the drive motor 300 will correspondingly
rotate the drive shaft 302, which in turn threadingly engages the
drive plate 304 to vertically displace the sensor assembly 24 in
the direction of arrows A. The speed of the drive motor 300 is
preferably controllable so as to correspondingly adjust or regulate
the rate of vertical displacement of the sensor assembly 24. As
illustrated in FIG. 4, the adjustment mechanism 26 provides the
capability to selectively adjust the height h.sub.1 of the sensor
assembly 24 relative to the base unit 22 within a range of
operational positions. In a preferred embodiment of the invention,
the adjustment mechanism 26 is configured to provide approximately
thirty-six (36) inches of vertical adjustment. However, it should
be understood that other ranges of vertical adjustment are also
contemplated as falling within the scope of the present invention,
including vertical adjustments and/or vertical heights of greater
than thirty-six (36) inches.
[0055] As illustrated in FIG. 2, the adjustment mechanism 26 is
housed within the interior region 164 of the vertical support
column 160 (the support column 160 having been removed from FIG. 9
for purposes of clarity). The drive motor 300 is secured to the
vertical support column 160, and more specifically to the side wall
162b, via a number of fasteners 310 or by any other means for
attachment. The driven end of the drive shaft 302 is rotatably
coupled to the output shaft 312 of the drive motor 300 via a
coupling 314, with the free end of the drive shaft 302 rotatably
mounted to an upper mounting plate 316 via a bushing or bearing
318. The drive plate 304 defines an internally threaded opening 320
that threadingly receives the drive shaft 302. The threaded opening
320 may be machined directly into the drive plate 304 or may be
defined by an internally threaded bushing insert. The drive plate
304 is attached to the connector bracket 306 by an intermediate
L-shaped bracket 322 which is secured to the drive plate 304 and
the connector plate 306 via a number of fasteners 324 or by any
other means for attachment. Alternatively, the drive plate 304 and
the connector bracket 306 may be integrally formed as a single
piece.
[0056] As most clearly shown in FIGS. 2 and 9, in the illustrated
embodiment of the invention, the adjustment mechanism 26 includes a
pair of guide tracks or channels 330 and 332 positioned at the
front and rear of the support column 160. Front and rear portions
of the connector bracket 306 are slidably displaced along the guide
tracks 330, 332 to stabilize the connector bracket 306 and the
sensor assembly mounting structure 200, particularly during
adjustment of the height h.sub.1 of the position sensors 202. In
one embodiment, the guide tracks 330, 332 are defined by a pair of
vertically-extending bars or rods 334a, 334b spaced apart a
distance sufficient to slidably receive the connector bracket 306
therebetween. The guide bars 334a, 334b are interconnected via an
upper and lower studs or fasteners 336a, 336b. The studs 336a, 336b
may define an externally threaded portion adapted for threading
engagement within a threaded opening in one of the guide bars to
provide a means for adjusting the width of the guide tracks 330,
332.
[0057] In one embodiment of the invention, the connector bracket
306 is pivotally attached to a mounting flange 340 extending from
the base portion 206 of the sensor assembly mounting structure 200
via a pivot pin 342. In this manner, the sensor assembly 24 is
allowed to pivot about a pivot axis P.sub.2 between an operational
position (FIG. 1), wherein the mounting arms 204a, 204b are
arranged substantially perpendicular to the vertical support column
160, and a storage or transport position (FIG. 10) wherein the
mounting arms 204a, 204b are arranged substantially parallel with
the vertical support column 160. The sensor assembly 24 is
selectively maintained in the operational position illustrated in
FIG. 1 via abutment of an end surface of connector bracket 306
against the base portion 206 of the sensor assembly mounting
structure 200. However, other means for selectively maintaining the
sensor assembly 24 in the operational position are also
contemplated as would occur to one of skill in the art. As should
be appreciated, pivoting the sensor assembly 24 to the collapsed
configuration illustrated in FIG. 10 provides for a more compact,
lower profile configuration to facilitate transport of the exercise
device 20 and/or storage of the exercise device 20 in areas having
limited space, such as, for example, under a bed or in a
closet.
[0058] Although a specific embodiment of an adjustment mechanism
has been illustrated and described herein for adjusting the height
h.sub.1 of the position sensors 202, it should be understood that
other means for adjustment are also contemplated as falling within
the scope of the present invention. For example, a linear actuator
could alternatively be used to adjust the height h.sub.1, including
various types and configurations of electric linear drives or
pneumatic cylinder arrangements. A gear driven system is also
contemplated, such as, for example, a rack and pinion type system.
Additionally, a cabling system powered by a rotational or linear
drive may also be used to adjust the height h.sub.1. In another
embodiment, a crank handle or a ratchet handle may be used to drive
various types and configurations of adjustment mechanisms. In a
further embodiment of the invention, the height h.sub.1 may be
manually adjusted by hand and locked into a selected position via a
lock pin or clamp. Other means for adjusting the height h.sub.1 are
also contemplated as would occur to one of skill in the art. It
should also be understood that in other embodiments of the
invention, the sensor assembly 24 and the sensors 202 may be fixed
at a predetermined non-adjustable height h.sub.1.
[0059] According to one embodiment of the invention, as illustrated
in FIG. 1, the control panel 28 is securely mounted to the upper
end of the support column 160. The control panel 28 may be
rotatably and/or pivotally mounted to the upper end of the support
column 160 to accommodate for adjustment of the angular position
and/or orientation of the control panel 28 relative to the user or
a third party.
[0060] As discussed above, the control panel 28 controls and/or
monitors the operation of the various electrical components
associated with the exercise device 20. For example, the control
panel 28 functions to activate/deactivate the light sources 132 in
the base unit 22, power and receive feedback signals from the
pressure sensors 190 in the base unit 22, power and receive
feedback signals from the position sensors 202 of the position
sensor assembly 24, and power and control operation of the electric
drive motor 302 of the adjustment mechanism 26. As should be
appreciated, the control panel 28 may also be used to control,
monitor and/or power other electrical components associated with
the exercise device 20 or other ancillary equipment. Power can be
supplied to the control panel 28 and other electrical components
via household current, one or more batteries, and/or by any other
type of power supply known to those of skill in the art.
[0061] The control panel 28 is equipped with an electronic circuit
board (not shown), a programmable controller (not shown) and/or any
other type of electronic control system known to those of skill in
the art. The control panel 28 preferably includes various buttons
or keys 400 or other types of input devices (e.g., knobs, switches,
a touch pad, etc.) to provide a user interface for inputting
information and/or data to control operation of the various
components and features associated with the exercise device 20. A
heart monitor (not shown) may also be provided to monitor the
user's heart rate, blood pressure, etc., the output of which may be
communicated to the control panel 28 via a wireless or direct-wired
connection.
[0062] The display 30 on the control panel 28 provides for direct
visualization of various parameters that are indicative of the
user's performance of an activity, such as, for example,
information or data relating to the frequency and duration of the
activity, the number of missteps or miscues, elapsed time, an
estimate of the number of calories burned, measured heart rate or
blood pressure, historical data relating to the activity, etc. The
display 30 may also be used to convey other information or data to
the user, such as, for example, component settings, a programming
menu and/or operating instructions (e.g., a help screen), etc. In
one embodiment of the invention, the display 30 is an LCD display.
However, other types of displays are also contemplated, including
plasma displays, CRT monitors, or any other type of display or
monitor that would occur to one of skill in the art.
[0063] In addition to the display 30, the control panel 28 also
includes a pair of indicator lights 402, 404 that provide visual
indications or cues to the user to elicit a response, such as, for
example, a jumping movement, and/or to provide visual confirmation
or feedback signals to the user indicating that a predetermined
parameter has been satisfied, such as, for example, jumping beyond
a predetermined height (e.g., beyond the sensing plane S). In one
embodiment, the indicator lights 402, 404 are of different colors
(e.g., red and green) to allow the user to quickly and easily
interpret the meaning behind the indication, cue, confirmation,
and/or feedback signal corresponding to illumination of either of
the lights 402, 404. The control panel 28 may also include a
speaker or any other device that is capable of emitting a sound or
tone to provide audible indications, cues, configurations and/or
feedback signals to the user.
[0064] The exercise device 20 may also be equipped with a remote
control device (not shown) configured to communicate with the
control panel 28 to control operation of the various electrical
components associated with the exercise device 20 from a remote
location. The remote control device may include a display to
provide remote visualization of various parameters associated with
the user's performance of an activity, component settings, etc. The
remote control device may be of the wireless type or may be hard
wired into the control panel 28. The use of a remote control device
may be particularly advantageous when a third party, such as, for
example, a coach, trainer or instructor is present.
[0065] As illustrated in FIGS. 1 and 2, the exercise device 20 may
be equipped with a pair of user supports or handrails 500a, 500b
positioned on each side of the base unit 22. In one embodiment of
the invention, the handrails 500a, 500b each include a rear portion
502 extending vertically from the base unit 22, a side portion 504
extending horizontally along the longitudinal axis L, and a front
portion 506 extending horizontally along the transverse axis T and
into engagement with the vertical support column 160. However,
other configurations of handrails 500a, 500b are also contemplated
as would occur to one of skill in the art. It should also be
understood that the exercise device 20 need not necessarily be
equipped with handrails.
[0066] Although the illustrated embodiment of the invention depicts
the side portions 504 of the handrails 5002, 500b as having a
generally linear configuration, it should be understood that the
side portions 504 may be angled or curved. In a further embodiment
of the invention, the side portions 504 have a generally circular
cross section defining an outer diameter of between about one (1)
inch and about three (3) inches to provide for secure and
comfortable grasping by the user. Additionally, the side portions
504 may be treated to provide a non-slip surface to reduce the
likelihood of user injury. Such a non-slip surface may be provided,
for example, by roughening the outer surface of the side portions
504 via knurling or peening, by applying a non-slip material or
coating to the outer surface of the side portions 504, and/or by
providing hand grips that are formed of a non-slip material, such
as, for example, plastic, rubber or foam.
[0067] In a further embodiment of the invention, the handrails
500a, 500b may be provided with a means for adjusting the height of
the side portions 504 relative to the support pad 104 to
accommodate users of different heights and/or different arm
lengths. In one such embodiment, the vertically-extending rear
portions 502 of the handrails 500a, 500b may include an inner tube
portion that is telescopically received with an outer tube portion
to provide for adjustment of the height of the side portions 504
relative to the support pad 104, and a clamp or fastener device,
such as, for example, a pin or push button for locking the side
portions 504 at a select height.
[0068] The handrails 500a, 500b are preferably selectively
detachable from the base unit 22 and the support column 160 to
accommodate transformation of the exercise device 20 into the
collapsed configuration illustrated in FIG. 10 to facilitate
transport and/or storage. In one embodiment of the invention, the
ends of the vertical rear portions 502 of the handrails 500a, 500b
are slidably received within mounting sleeves 508 extending
upwardly from the mounting rails 130a, 130b of the base unit 22.
Similarly, the ends of the horizontal front portions 506 of the
handrails 500a, 500b are slidably received within mounting sleeves
510 extending laterally from the side walls 162a, 162b of the
support column 160 (FIG. 2). The ends of the handrails 500a, 500b
may be removably secured within the mounting sleeves 508, 510 via
setscrews, pins, clamps, a friction fit, or by any other means of
releasable engagement known to those of skill in the art. In an
alternative embodiment of the invention, the handrails 500a, 500b
may be pivotally attached to the base unit 22 in such a manner as
to allow the handrails 500a, 500b to be folded to accommodate
transformation of the exercise device 20 into the collapsed
configuration illustrated in FIG. 10.
[0069] Having described the various components, functions and
features associated with the exercise device 20, further details
regarding the use and operation of the exercise devices will now be
discussed below. According to one form of the invention, the
exercise device 20 may be used to simulate the activity of jumping
rope. In another embodiment of the invention, the exercise device
20 may be used in association with walking or running in place.
With regard to the embodiment of the invention directed to the
exercise activity involving a simulated jump rope, the control
panel 28 is configured and/or programmed to activate (turn on) the
light sources 132 in a sequential manner, preferably in a front to
back direction (e.g., from the front of the base unit toward the
rear of the base unit). However, it should be understood that the
light sources 132 may alternatively be activated in a sequential
manner in a back to front direction. As should be appreciated,
activation of the light sources 132 associated with a corresponding
light channel 170 will illuminate a discrete band or strip of the
support pad 104 directly above that light channel 170. As should
also be appreciated, upon the sequential activation of each light
source 132, the adjacent light source 132 toward the front of the
base unit 22 will be deactivated (turned off).
[0070] The sequential activation/deactivation of the light sources
132 has the effect of providing a virtual simulation of a jump rope
passing beneath the user's feet. As illustrated in FIG. 8 and
described above, the light channels 170' positioned toward the
front and rear of the base unit 22 may be configured to have
varying degrees of lateral curvature to provide an even more
realistic simulation of a jump rope passing beneath the user's
feet. The speed and frequency at which the light sources 132 are
sequentially activated and deactivated can be varied via the
control panel 28 to adjust the speed and frequency (e.g., cadence)
at which the virtual jump rope passes beneath the user's feet,
thereby enabling the user to control his or her aerobic workout
level.
[0071] As the light sources 132 are sequentially activated and
deactivated, the user is cued to react by "jumping over" the
virtual jump rope (i.e., the illuminated light band extending
across the support pad 104) as the virtual jump rope passes
directly beneath the user's feet. Additionally, the user must jump
high enough to clear the virtual jump rope. The position sensors
202 can function to verify or confirm that the user has in fact
cleared the virtual jump rope as it passes beneath the user's feet.
The pressure sensors 190 associated with the pressure sensitive pad
or strip 108 may also be used to verify that the user actually
jumped off of the support pad 104 and/or that the user jumped at
the appropriate time to clear the virtual jump rope.
[0072] As should be appreciated, if the user jumps high enough to
extend above the sensing plane S (i.e., above the light beams B),
the position sensors 202 will send a confirmation signal to the
control panel 28 that a successful jump has been executed. In turn,
a visual and/or non-visual indication may be provided to confirm
that the jump was successful. In one embodiment, one of the
indicator lights 402, 404 (e.g., a green light) will illuminate to
provide visual confirmation to the user that the jump was
successful. However, other types of indications are also
contemplated, such as, for example, other types of lights,
graphical symbols, audible signals, and/or other types of visual
and/or non-visual indications that would occur to one of skill in
the art. If the user fails to extend above the sensing plane S, at
least one of the light beams B will remain broken by the user's
legs or feet. As a result, one or more of the position sensors 202
will send a signal to the control panel 28 indicating that the jump
was unsuccessful (e.g., a miscue). In turn, a visual and/or
non-visual indication may be provided to confirm that the jump was
successful, such as, for example, illumination of one of the
indicator lights 402, 404 (e.g., a red light) to provide visual
confirmation to the user that the jump was unsuccessful. The light
402, 404 indicating a successful jump (e.g., the green light) will
preferably remain illuminated until an unsuccessful jump has been
detected. As discussed above, the height h.sub.1 of the position
sensors 202 may be adjusted to correspondingly adjust the height at
which the user must jump to clear the virtual jump rope. As a
result, the user is able to control his or her anaerobic workout
level. It should be understood that the height h.sub.1 of the
position sensors 202 may be adjusted before or during the user's
workout, and may be adjusted manually by the user or automatically
by the control panel 28.
[0073] In one embodiment of the invention, the position sensors 202
may be sequentially activated/deactivated substantially
synchronously with the sequential activation/deactivation of the
light sources 132. In other words, the activation/deactivation of
the position sensors 202 may be configured to substantially track
the activation/deactivation of the light sources 132. As discussed
above, the light beams B generated by the position sensors 202 may
be configured to be visible by the user so as to provide a visual
indication of the selected height h.sub.1 of the position sensors
202 and the sensing plane S relative to the support pad 104. In
this manner, the light beams B provide further simulation of the
virtual jump rope passing beneath the user's feet while at the same
time providing the user with an easily identifiable indication as
to the height the user must jump to clear the virtual jump rope. In
a further embodiment of the invention, additional light sources or
cueing devices may be mounted to one or both of the mounting arms
204a, 204b of the sensor frame 200 which illuminate substantially
synchronously with the respective light sources 132 to provide
further indication as to when and how high the user must jump to
clear the virtual jump rope. Non-visual signaling devices, such as,
for example, audible signaling devices, may also be mounted to one
or both of the mounting arms 204a, 204b of the sensor frame 200 to
provide further indication as to when and how high the user must
jump to clear the virtual jump rope.
[0074] The pressure sensors 190 associated with the pressure
sensitive pad or strip 108 may be used in addition to or in lieu of
the position sensors 202 to verify or confirm whether a jump was
successful or unsuccessful. As should be appreciated, if the user
jumps off of the support pad 104 at the appropriate time as the
virtual jump rope passes beneath the user's feet, the pressure
sensors 190 will send a confirmation signal to the control panel 28
that a successful jump has been executed and one of the indicator
lights 402, 404 (e.g., a green light) will illuminate. However, if
the user fails to jump off of the support pad 104 at the
appropriate time, one or more of the pressure sensors 190 will send
a signal to the control panel 28 indicating that the jump was
unsuccessful and one of the indicator lights 402, 404 (e.g., a red
light) will illuminate. The light 402, 404 indicating a successful
jump (e.g., the green light) will preferably remain illuminated
until an unsuccessful jump has been detected.
[0075] As discussed above, the control panel 28 may be configured
to generate a visual signal on the display 30, an audible signal,
and/or other types of signals to indicate that a particular jump
was successful or unsuccessful. Additionally, it should be
understood that the "signal" sent to the control panel 28 by the
position sensors 202 and/or the pressure sensors 190 can take the
form of an actual electronic signal or may take the form of the
absence of an electronic signal. It should also be understood that
the control panel 28 may be programmed with predetermined workout
parameters or settings that will automatically vary the speed and
frequency of the virtual jump rope passing beneath the user's feet
and/or the height at which the user must jump to clear the virtual
jump rope. In this manner, the user may work out without
interruption or distraction and without having to manually change
the parameters or settings of the exercise device 20.
[0076] The anaerobic benefits of the exercise device can be
enhanced via the use of hand, waist or ankle weights in conjunction
with the rope jumping activity. Notably, unlike the actual activity
of jumping rope, the virtual jump rope generated by the exercise
device 20 frees up the user's hands to allow the user to perform
other functions (e.g., grasping hand weights, balancing via the
handrails 500a, 500b, etc.). Additionally, the user does not have
to concentrate on the proper handling of the rope and keeping their
feet and legs clear of the rope, thereby enabling the user to
concentrate solely on the jumping activity itself. As a result,
user safety and comfort is significantly enhanced. Moreover, the
user has a totally free range of motion with regard to both their
hands and legs.
[0077] With regard to the embodiment of the invention directed to
use of the exercise device 20 in association with the activity of
walking or running in place, as illustrated in FIGS. 1 and 3, the
base unit 22 and the sensor assembly 24 are configured to define a
first zone Z.sub.1 and a second zone Z.sub.2, with each of the
zones extending generally along the transverse axis T. However, it
should be understood that the base unit 22 and the sensor assembly
24 may be divided into any number of zones, including three or more
zones, and that the zones may extend in other directions, including
a direction extending generally along the longitudinal axis L. Each
of the first and second zones Z.sub.1, Z.sub.2 includes a number of
the light sources 132 that selectively illuminate a corresponding
number of the light channels 170, and a number of position sensors
202 that emit a corresponding number of the light beams B. Although
the illustrated embodiment of the invention depicts each of the
zones Z.sub.1, Z.sub.2 as having four (4) light channels 170 and
four (4) light beams B, it should be understood that other
configurations are also contemplated, including configurations
wherein each of the zones Z.sub.1, Z.sub.2 include a single light
channel 170 and a single light beam B.
[0078] In the illustrated embodiment of the invention, the user
faces a transverse direction (i.e., toward either side of the base
unit 22) and places one foot (e.g., the right foot) within the
first zone Z.sub.1 and the other foot (e.g., the left foot) within
the second zone Z.sub.2. The control panel 28 is configured and/or
programmed to activate and deactivate the light sources 132 in the
first and second zones Z.sub.1, Z.sub.2 in an alternating manner.
Activation of the light sources 132 in the first zone Z.sub.1 cues
the user to react by raising his or her right foot off of the
support pad 104. After a period of time, the light sources 132 in
the first zone Z.sub.1 will deactivate, thereby cueing the user to
react by placing his or her right foot back onto the support pad
104. The light sources 132 in the second zone ZS will then
activate, cueing the user to react by raising his or her left foot
off of the support pad 104. In one embodiment, activation of light
sources 132 in the second zone ZS occurs virtually simultaneously
with deactivation of the light sources 132 in the first zone
Z.sub.1. However, a delay between activation and deactivation of
the light sources 132 associated with the first and second zones
Z.sub.1, Z.sub.2 is also contemplated. After a period of time, the
light sources 132 in the second zone Z.sub.2 will deactivate,
thereby cueing the user to react by placing his or her left foot
back onto the support pad 104. The light sources 132 in the first
zone Z.sub.1 will once again activate, and the
activation/deactivation sequence of the first and second zones
Z.sub.1, Z.sub.2 will be repeated indefinitely. It should be
understood that in another embodiment of the invention,
deactivation of the light sources 132 may be used to cue the user
to raise his or her foot off of the support pad 104, while
activation of the light sources cues the user to place his or her
foot back onto the support pad 104.
[0079] As should now be appreciated, activation and deactivation of
the first and second zones Z.sub.1, Z.sub.2 in an alternating
manner provides the user with visual indications which, if
followed, will cue the user to walk or run in place. As should also
be appreciated, the speed at which the first and second zones
Z.sub.1, Z.sub.2 are activated and deactivated can be varied via
the control panel 28 to adjust the speed (i.e., cadence) at which
the user must walk or run in place, thereby enabling the user to
control his or her aerobic workout level. The user may set the
speed before beginning the workout or may manually adjust the speed
setting at any point during the workout. Additionally, the control
panel 28 may be programmed with various speed settings that remain
constant throughout the user's workout, or which are automatically
adjust at various points during the user's workout. In this manner,
the user may work out without interruption or distraction.
[0080] In another aspect of the invention, the position sensors 202
may be used to verify or confirm that the user raised his or her
foot off of the corresponding zone Z.sub.1, Z.sub.2 at the
appropriate time and at the appropriate elevation above the upper
surface 105 of the support pad 104. In a further aspect of the
invention, pressure sensors 190 located beneath respective ones of
the first and second zones Z.sub.1, Z.sub.2 may also be used to
verify that the user raised his or her foot off of the
corresponding zone Z.sub.1, Z.sub.2 at the appropriate point in
time.
[0081] As should be appreciated, if the user raises his or her foot
high enough to extend above the sensing plane S (i.e., above the
light beams B), the position sensors 202 will send a confirmation
signal to the control panel 28 indicating that the user is
successfully performing the walking/running activity. In turn, one
of the indicator lights 402, 404 (e.g., a green light) will
illuminate to provide visual confirmation to the user that he or
she is performing successfully. However, if the user fails to
extend above the sensing plane S, at least one of the light beams B
will remain broken by the user's leg or foot. As a result, one or
more of the position sensors 202 will send a signal to the control
panel 28 indicating the user's unsuccessful performance of the
activity (e.g., a misstep or miscue). In turn, one of the indicator
lights 402, 404 (e.g., a red light) will illuminate to provide
visual confirmation to the user regarding his or her unsuccessful
performance of the activity. The light 402, 404 indicating
successful performance (e.g., the green light) will preferably
remain illuminated until a misstep or miscue has been detected. As
discussed above, the height h.sub.1 of the position sensors 202 may
be adjusted relative to the upper surface 105 of the support pad
104, thereby resulting in an adjustment to the height at which the
user must raise his or her feet to clear the light beams B. As a
result, the user is able to control his or her anaerobic workout
level. It should be understood that the height h.sub.1 of the
position sensors 202 may be adjusted before or during the user's
workout, and may be adjusted manually by the user or automatically
by the control panel 28.
[0082] In one embodiment of the invention, the position sensors 202
associated with each of the respective zone Z.sub.1, Z.sub.2 may be
activated/deactivated in an alternating manner to correspond with
the alternating activation/deactivation of the light sources 132.
In other words, the activation/deactivation of the position sensors
202 within the respective zone Z.sub.1, Z.sub.2 may be configured
to substantially track the activation/deactivation of the light
sources 132 within the respective zone Z.sub.1, Z.sub.2. As
discussed above, the light beams B generated by the position
sensors 202 may be configured to be visible by the user so as to
provide a visual indication of the selected height h.sub.1 of the
position sensors 202 and the sensing plane S relative to the
support pad 104. In this manner, the light beams B provide the user
with an easily identifiable indication as to the height at which
the user's foot must be raised to clear the sensing plane S. In a
further embodiment of the invention, additional light sources or
cueing devices may be used to cue the user as to when his or her
foot should be raised off of the support pad 104. In one
embodiment, additional light sources or cueing devices may be
mounted to one or both of the mounting arms 204a, 204b, or at other
locations, which illuminate substantially synchronously with the
light sources 132 within the respective zone Z.sub.1, Z.sub.2 to
provide further indication as to when the user must raise his or
her foot off of the support pad 104.
[0083] The pressure sensors 190 located beneath respective ones of
the first and second zones Z.sub.1, Z.sub.2 may be used in addition
to or in lieu of the position sensors 202 to verify or confirm
whether the user is performing the walking/running activity
successfully or unsuccessfully. As should be appreciated, the
pressure sensors 190 may be used to verify or confirm that the user
raised his or her foot off of the corresponding zone Z.sub.1,
Z.sub.2 at the appropriate point in time. If the user's performance
is successful, the pressure sensors 190 will send a confirmation
signal to the control panel 28 and one of the indicator lights 402,
404 (e.g., a green light) will illuminate. However, if the user is
unsuccessful, one or more of the pressure sensors 190 will send a
signal to the control panel 28 and one of the indicator lights 402,
404 (e.g., a red light) will illuminate. The light 402, 404
indicating successful performance (e.g., the green light) will
preferably remain illuminated until a misstep or miscue has been
detected.
[0084] As discussed above, the control panel 28 may be configured
to generate a visual signal on the display 30, an audible signal,
and/or other types of signals to indicate that the user's
performance was successful or unsuccessful. Additionally, it should
be understood that the "signal" sent to the control panel 28 by the
position sensors 202 and/or the pressure sensors 190 can take the
form of an actual electronic signal or may take the form of the
absence of an electronic signal.
[0085] Referring to FIG. 11, shown therein is an alternative
embodiment of the exercise device 20 illustrated and described
above. In many ways, the exercise device 20' is configured similar
to the exercise device 20, including a base unit 22, an adjustable
position sensor assembly 24, an adjustment mechanism 26, a control
panel 28, and a monitor or display 30. However, the exercise device
20' is additionally equipped with a stationary position sensor
assembly 50.
[0086] In one embodiment of the invention, the stationary position
sensor assembly 50 includes a number of sensor elements that serve
to determine the position and/or orientation of the user's feet
relative to the upper surface 105 of the support pad 104, the
details of which will be discussed below. In other embodiments of
the invention, the stationary position sensor assembly 50 may be
used in a manner similar to that of the adjustable sensor assembly
24 to determine whether or not the user's response to a cue or
signal satisfies a predetermined objective or goal, such as, for
example, a predetermined elevation and/or an elapsed period of
time. In the illustrated embodiment, the stationary position sensor
assembly 50 is used in combination with the adjustable position
sensor assembly 24. However, it should be understood that in other
embodiments of the invention, the stationary position sensor
assembly 50 may be used without the adjustable position sensor
assembly 24.
[0087] According to one embodiment of the invention, the stationary
position sensor assembly 50 is generally comprised of a pair of
spaced apart mounting structures 52a, 52b extending along the
length of the base unit 22 in a direction generally parallel with
the longitudinal axis L, and a pair of spaced apart mounting
structures 54a, 54b extending across the width of the base unit 22
in a direction generally parallel with the transverse axis T. The
mounting structures 52a, 52b and 54a, 54b are preferably securely
mounted to the support pad 104 or to other portions of the base
unit 22. A plurality of position sensors 56 are mounted to each of
the mounting structures 52a, 52b and 54a, 54b. Each of the position
sensors 56 are preferably positioned at a predetermined distance
above the support surface 105 so as to define a sensing grid G
arranged approximately parallel with the support surface 105. In
this manner, the position sensors 56 will be able to detect the
presence or absence of the user's feet along the sensing grid
G.
[0088] In one embodiment of the invention, the mounting structures
52a, 52b and 54a, 54b are configured substantially identical to one
another and have a tubular configuration defining a hollow interior
region for receiving the sensors 56. In a specific embodiment, the
position sensors 56 are mounted within the tubes 52a, 52b and 54a,
54b in a manner similar to that described above with regard to the
adjustable position sensor assembly 24 (e.g., via a mounting
bracket similar to that of mounting bracket 216 and generally
aligned with sensor apertures in the tubes similar to sensor
apertures 212). However, it should be understood that other
configurations of the mounting tubes 52a, 52b and 54a, 54b are also
contemplated as falling within the scope of the present
invention.
[0089] In one embodiment of the invention, the position sensors 56
are of the photoelectric type, with each position sensor 56
including opposing emitter and receiver units configured similar to
the emitter and receiver units E, R illustrated and described above
with regard to the position sensors 202 associated with the
adjustable position sensor assembly 24. Similar to the position
sensors 202 illustrated in FIG. 3, the opposing pairs of the
emitter and receiver units are preferably arranged in a staggered
or alternating configuration such that the receiver units are
separated from one another by an intermediate emitter unit. As a
result, the likelihood that a receiver unit will erroneously detect
the light beam emitted from the wrong emitter unit is significantly
reduced. However, it should be understood that other configurations
are also contemplated, including configurations where all of the
emitter units are mounted to one of the mounting tubes (e.g., tubes
52a, 54a) and all of the receiver units are mounted to the opposite
mounting tube (e.g., tubes 52b, 54b).
[0090] Although the position sensors 56 have been described as
photoelectric-type sensors, with each position sensor 56 including
an emitter unit and a receiver unit, it should be understood that
other types and configurations of position sensors are also
contemplate as falling within the scope of the present invention.
For example, instead of having separate emitter and receiver units,
in other embodiments of the invention, the emitter and receiver
elements may be integrated into a single unit, with an optical
reflector mounted opposite the integrated position sensor to
complete the optical sensor circuit. Additionally, in lieu of
photoelectric-type sensors, the stationary position sensor assembly
50 may utilize other types of position sensors, including various
types and configurations of laser sensors, fiber optic sensors,
optical sensors, motion sensors, infrared sensors, thermal sensors,
ultrasonic sensors, capacitive sensors, proximity sensors, or any
other type of position sensor that would occur to one of skill in
the art.
[0091] As illustrated in FIG. 11, the sensor assembly mounting
tubes 52a, 52b and 54a, 54b extend about the outer perimeter of the
support pad 104 and are positioned directly above the support
surface 105. The position sensors 56 are disposed at intermittent
locations along the mounting tubes 52a, 52b and 54a, 54b,
preferably at uniform intervals, such that the longitudinal
distance d.sub.L separating the position sensors 56 associated with
the mounting tubes 52a, 52b is approximately equal to the
transverse distance d.sub.T separating the position sensors 56
associated with the mounting tubes 54a, 54b. In this manner, the
transverse beams of light B.sub.T emitted/received by the position
sensors 56 associated with the mounting tubes 52a, 52b and the
longitudinal beams of light B.sub.L emitted/received by the
position sensors 56 associated with the mounting tubes 54a, 54b
will form the sensing grid G at a predetermined distance above and
preferably substantially parallel to the support surface 105.
[0092] As should be appreciated, the longitudinal and transverse
distances d.sub.L, d.sub.T separating the position sensors 56 may
be increased/decreased to correspondingly vary the sensing density
of the sensing grid G, which would in turn increase/decrease the
sensing accuracy of the stationary position sensor assembly 50. As
should also be appreciated, the longitudinal and transverse
distances d.sub.L, d.sub.T separating the position sensors 56 need
not necessarily be equal to one another, but may instead take on
different values to correspondingly vary the sensing
density/accuracy along the longitudinal axis L relative to the
sensing density/accuracy along transverse axis T. Additionally,
although the position sensors 56 and the sensing grid G are
illustrated as being positioned just above the support surface 105,
it should be understood that the position sensors 56 and the
sensing grid G may alternatively be positioned at other
predetermined elevations above the support surface 105.
[0093] As should be appreciated, when there is no obstruction
present between respective pairs of the emitter and receiver units,
the corresponding light beams B.sub.T, B.sub.L will remain unbroken
and the receiver units will communicate a signal to the control
panel 28 indicating an uninterrupted sensor condition. However,
when any of the light beams B.sub.T, B.sub.L are broken by an
obstruction (e.g., by the user's feet) the receiver units will
communicate a signal to the control panel 28 indicating an
interrupted sensor condition. Accordingly, the position sensors 56
are capable of detecting the presence or absence of the user's feet
along the sensing grid G, and are likewise capable of determining
the position and/or orientation of the user's feet relative to the
base unit 22, the details of which will be discussed below.
[0094] As indicated above, in one embodiment of the invention, the
stationary position sensor assembly 50 may be used in a manner
similar to that of the adjustable sensor assembly 24 to determine
whether or not the user's response to a cue or signal satisfies a
predetermined objective or goal. For example, the position sensors
56 may be used to determine whether or not the user has jumped or
otherwise extended vertically beyond the sensing grid G, which for
practical purposes would determine whether or not either of the
user's feet have left the support surface 105 at the appropriate
time in response to a signal or cue. The position sensors 56 may
also be used to determine the approximate point in time in which
the user's feet return to the support surface 105. In this regard,
the position sensors 56 may be used in manner similar to that of
the pressure sensors 190.
[0095] In a further embodiment of the invention, the stationary
position sensor assembly 50 may be used to determine the position
and/or orientation of the user's feet prior to, during, and/or
after an activity, such as, for example, a jumping activity or a
walking/running activity. With regard to a vertical jumping
activity, immediately prior to initiation of a signal or cue
instructing the user to jump off of the support surface 105, the
position sensors 56 may be used to determine the position and/or
orientation of the user's feet by determining which of the position
sensors 56 are indicating an interrupted condition (i.e., an
obstruction of the light beams B.sub.T, B.sub.L by the user's
feet). The receiver units indicating an interrupted condition will
communicate a signal to the control panel 28, with the control
panel 28 in turn determining or "plotting" the position and/or
orientation of the user's feet along the sensing grid G.
Additionally, immediately after completion of the jump (i.e., when
the user's feet return to the support surface 105), the position
sensors 56 may once again be used to determine or plot the position
and/or orientation of the user's feet. In this manner, the
stationary position sensor assembly 50 may be used to determine the
overall efficiency of the user's vertical jump attempt. For
example, if the user's feet are determined to be in approximately
the same position and orientation immediately after the jump
attempt as they were immediately prior to the jump attempt, the
measured efficiency of the jump will be high. However, if the
user's feet are in a different position and/or orientation, the
measured efficiency of the jump will be comparatively low.
[0096] With regard to a walking/running activity, plotting the
position and orientation of the user's feet during a
walking/running activity may provide useful feedback to measure and
monitor walking/running mechanics. This may be particularly useful
with regard to therapeutic applications to provide a therapist,
trainer or other personnel with real time feedback regarding the
positioning and orientation of the user's feet during a
walking/running activity. It should be understood that the
stationary position sensor assembly 50 may be used in applications
other than those specifically described above, including the use of
multiple parallel sensor assemblies, and that the particular
embodiments discussed herein are exemplary, it being understood
that other applications are contemplated as falling within the
scope of the present invention.
[0097] Although the position sensor assemblies 24 and 50 and the
pressure sensitive pad or strip 108 have been described as being
primarily used as a means to provide a signal or indication
corresponding to the user's position relative to the support
surface 105, it should be understood that these elements may also
be used as a means to measure parameters associated with the user's
performance of various activities. For example, with regard to a
jump rope simulation activity, the position sensor assemblies 24,
50 and/or the pressure pad 108 may be used to measure the jump
speed, cadence or jump height of the user. This measurement may in
turn be used to adjust the settings of the exercise device (e.g.,
speed or cadence at which the light channels 170 are
activated/deactivated and/or the height of the sensor assembly 24)
to more closely match the capabilities of the user. Similarly, with
regard to the activities of walking or running in place, the
position sensor assemblies 24, 50 and/or the pressure pad 108 may
likewise be used to measure parameters associated with walking or
running (e.g., speed, distance, stride length, foot height, etc.),
which may in turn be used to adjust the settings of the exercise
device to more closely match the capabilities of the user. A
similar arrangement may also be used in association with the
vertical jumping activity.
[0098] In a further embodiment of the invention, one or more of the
exercise device embodiments illustrated and described above may
include a closed loop feedback mode whereby the user would have the
ability, if desired, to input their weight, the length of time they
wish to jump, the cadence at which they would like to jump, how
many calories they would like to burn, the height that they want to
jump, and/or any other parameter or criteria relating to the user
and/or to the activity of the user, all as a means of goal setting.
The user would be able to select any one of the inputs, all of the
inputs, or any combination of the inputs. In addition, the exercise
device would have the ability to break down the total exercise time
into smaller time segments whereby the desired speed and height
might change from one exercise segment to another.
[0099] Regardless of the inputs selected, the light channels below
the user's feet will illuminate sequentially faster as the user
jumps faster and slower as the user jumps slower. The light
channels will illuminate sequentially as soon as the sensors
indicate that the user's feet have left the jumping surface,
thereby showing the virtual jump rope successfully passing beneath
the user's feet. Should the user desire to merely jump
indiscriminately at various cadences and heights and be timed as to
how long the user has been exercising and be provided with feedback
with regard to the selected exercise activity, the device will
permit this as well. The user will start the device and jump at a
selected cadence and height, either of which can be automatically
changed by jumping at a cadence that is faster/slower and/or
higher/lower, completely at the user's discretion. The device would
then provide immediate feedback as to how fast they are jumping (in
jumps per minute or JPMs), how high they are jumping (in inches or
centimeters), how many calories per hour they are burning, how many
total calories they have burned during the session, how long they
have been exercising, and/or how long they have to jump to achieve
their goal. In addition, an average cadence and average rope height
will be calculated for the entire exercise session. If the user
would like to merely count calories, they can also achieve this by
simply jumping on the device.
[0100] If preprogrammed goals are selected for speed and height,
and those goals are being met, a green light will illuminate or
another type of indicia will be activated with every successful
jump, and the display will reflect the measured instantaneous speed
and height. If one or both of the parameters are not being met
(i.e., if the user is jumping too slow or not jumping high enough),
a red light will illuminate or another type of indicia will be
activated with every unsuccessful jump until the deficiency is
remedied. For example, the display which illustrates the measured
speed at which the user is jumping will flash repeatedly in the
form of a flashing number if the user's cadence is too slow, and/or
the display which illustrates the measured jump height will show a
flashing number if the jump height is too low. In addition, an
average cadence and average rope height will be calculated for the
entire session. Also, one or more displays may show the percentage
of jumps that have met or exceeded the speed goal and/or the
percentage of jumps that have met or exceeded the height goal.
[0101] If the user wishes to merely input the number of calories
they would like to burn, they can input their weight, desired
cadence and desired rope height and the device will calculate the
time required to achieve this goal. The calculated time to meet the
calorie goal will then be displayed and counted down. The device
will still continuously calculate calories burned based on the
actual exercise performed. If the user falls short of their calorie
goal based on their activity at the end of the allotted time
period, the time display will reset showing the amount of
additional time that will be required based on an average of the
activity level of the user throughout the duration of the original
time period calculated. If the user does not select a cadence and
rope height, the device will merely count calories based on the
cadence and height of each jump and the time display will count up
until the caloric goal is achieved. The calorie calculations will
be estimated by data currently being collected through research
that is being performed on the device and will take both cadence
and rope height into consideration. In the absence of the user
inputting their weight, all calorie calculations will be based on
the assumption that the user weighs 150 pounds, which corresponds
to the use weight standard in the exercise industry.
[0102] Referring to FIGS. 12-19, shown therein are exercise devices
800, 900 and 1000 according to further forms of the present
invention. As will be discussed in greater detail below, the
exercise devices 800, 900 and 1000 include features that provide a
workout to both the upper and lower body of the user. The exercise
device 800 is generally comprised of a lower body base unit
configured similar or identical to the exercise device 20
illustrated and described above for providing a workout of the
lower body, in combination with an upper body unit 802 for
simultaneously providing a workout of the upper body. Similarly,
the exercise device 900 is generally comprised of a lower body base
unit configured similar or identical to the exercise device 20
illustrated and described above for providing a workout of the
lower body, in combination with an upper body unit 902 for
simultaneously providing a workout of the upper body. The exercise
device 1000 is also generally comprised of a lower body base unit
configured similar or identical to the exercise device 20
illustrated and described above for providing a workout of the
lower body, in combination with an upper body unit 1002 for
simultaneously providing a workout of the upper body.
[0103] It should be understood, however, that in other embodiments
of the invention, one or more of the exercise devices 800, 900 and
1000 may include modified versions of the lower body base unit 20.
For example, in an alternative embodiment, the size of the
footprint area of the support base 22 which defines the upper
support surface 105 may be enlarged to provide a greater area for
performing various user activities. The position sensor assembly 24
may likewise be enlarged to avoid interference with user
activities, or may be removed. Other changes, additions and/or
modifications to the lower body base unit 20, the support base 22,
the position sensor assembly 24, the adjustment mechanism 26 and/or
the control panel 28 are also contemplated. Additionally, the
exercise devices 800, 900 and 1000 need not necessarily include the
handrails 500a, 500b, and need not necessarily be configured to
fold down into a collapsed configuration, as described above and
illustrated in FIG. 10.
[0104] Referring to FIG. 12, the upper body unit 802 associated
with the exercise device 800 is generally comprised of a support
structure 804 and load members 806a, 806b that are operatively
coupled to the support structure 804. In the illustrated
embodiment, the support structure 804 is configured as a horizontal
mounting bar or block that is mounted to the vertical support
column 160 or to any other portion of the lower body base unit
20.
[0105] The load members 806a, 806b are preferably configured
identical to one another and are centrally positioned relative to
the vertical support column 160 and laterally offset from one
another by a distance d, which preferably corresponds to a distance
equal to or somewhat greater than the average spacing between a
user's arms or shoulders. However, other distances d are also
contemplated. In one embodiment, the load members 806a, 806b each
include a vertical beam or column portion 808 extending from the
support structure 804, a hook or curved transition portion 810
extending from the column portion 808, a flexibly elastic and
resilient portion 812 attached to the distal or free end of the
hook 810, and a ring or gripping portion 814 attached to an end of
the flexibly elastic and resilient portion 812. The load members
806a, 806b are preferably configured such that the rings 814 are
positioned at a height h above the upper support surface 105 of the
support base 22, which preferably corresponds to a height of the
user's hands when the user's arms are in a vertically extended
position. However, other heights h are also contemplated. The load
members 806a, 806b may be stationarily mounted in a fixed position,
or may be movably mounted and/or configured in a manner that allows
for adjustment to the distance d between the rings 814 and/or the
height h of the rings 814 above the upper support surface 105. Such
adjustment may provided via various types and configurations of
adjustments mechanisms, and may be manually adjustable or may be
automated and controlled via the control panel 28 and an actuator,
such as, for example, an electric, hydraulic or pneumatic motor, a
hydraulic or pneumatic cylinder, or any other rotary or linear
actuator that would occur to one of skill in the art.
[0106] In one embodiment, the flexibly elastic/resilient portions
812 are configured as flexible bands or straps that are formed of
an elastomeric material capable of being stretched and elastically
deformed as the user exerts an applied force, such as a pulling
force, on the rings 814, and which resiliently reforms and returns
toward a non-stretched or unstressed state upon release or
reduction of the pulling force on the rings 814. As a pulling force
is applied to the rings 814, the flexibly elastic/resilient
portions 812 are stretched from a first initial length l.sub.1 to a
second length l.sub.2, and returns toward the first initial length
l.sub.1 upon release or reduction of the pulling force. The
flexibly elastic/resilient portions 812 may be formed of any
material that is capable of being elastically deformed from an
initial state to a deformed state, and resiliently reformed back
toward the initial state. Such materials include, for example,
rubber or rubber-like materials, polymeric or plastic materials,
composite materials, metallic materials, shape-memory materials,
including polymer-based and metallic-based shape-memory materials,
or any other suitable elastic/resilient material that would occur
to one of skill in the art.
[0107] As should be appreciated, the user stands of the upper
support surface 105 of the support base 22 and may perform any of
the exercise activities described above in association with the
exercise device 20 to provide a workout of the lower body (e.g.,
jumping rope, walking/running in place, vertical jumping, etc.).
While exercising the lower body, the user may grasp and pull on the
rings 814 of the load members 806a, 806b to simultaneously provide
a workout of the upper body. As should be appreciated, the flexibly
elastic/resilient portions 812 are loaded as a force is applied to
the rings 814, which in turn resists movement of the user's arms as
the user pulls on the rings 814. However, in other embodiments of
the invention, the load members 806a, 806b may be configured
without the flexibly elastic/resilient portions 812, thereby
maintaining the rings 814 in a fixed position. In this embodiment,
the user may grasp the rings 814 and pull himself/herself off of
the support base 22 while performing an exercise activity. In this
manner, the weight of the user provides loading or resistance to
workout the user's upper body, which is similar to performing
chin-ups or other pull up exercises.
[0108] Although the load members 806a, 806b have been illustrated
and described as having a particular configuration, it should be
understood that other configurations are also contemplated. For
example, instead of providing the flexibly elastic/resilient
portion 812, the vertical column portion 808 and/or the hook
portion 810 may be formed of a flexibly elastic/resilient material
such that the load member 806a, 806b flex or bend as the user pulls
on the rings 814. In such embodiments, the load members 806a, 806b
could be configured as curved or arcuate-shaped rods or bars that
flex or bend in a manner similar to the flexible bars or rods
associated with a Bowflex.TM. home gym. Additionally, although the
load members 806a, 806b are illustrated as including rings 814,
other gripping devices are also contemplated for manual grasping by
the user, including various types and configurations of handles,
including devices configured similar to the ends of a jump
rope.
[0109] Referring to FIG. 13, the upper body unit 902 associated
with the exercise device 900 is generally comprised of a support
structure 904 and load members 906a, 906b that are coupled to the
support structure 904. In the illustrated embodiment, the support
structure 904 has an L-shaped configuration, including a vertical
support 910 mounted to the vertical support column 160 or to any
other portion of the support base 22, a horizontal support 912
extending transversely from the vertical support 910, a rear
horizontal bar 914 mounted to the vertical support 910, and a front
horizontal bar 916 mounted to the horizontal support 912. A pair of
pulleys/sheaves or eyelets 918 are mounted to the rear horizontal
bar 914, and a pair of pulleys/sheaves or eyelets 920 are mounted
to the front horizontal bar 916.
[0110] The load members 906a, 906b are preferably configured
identical to one another and are laterally offset from one another
by a distance d, which preferably corresponds to a distance equal
to or somewhat greater than the average spacing between a user's
arms or shoulders. However, other distances d are also
contemplated. In one embodiment, the load members 906a, 906b each
include a flexibly elastic and resilient element 930 attached to
the support base 22, a rope or cable 932 extending from the
flexibly elastic/resilient element 930 and wrapped about the rear
and front pulleys/sheaves or eyelets 918, 920, and a ring or
gripping portions 934 attached to an end of the cable 932. The
length of the cable 932 is preferably selected such that the rings
914 are positioned at a height h above the upper support surface
105 of the support base 22, which preferably corresponds to a
height of the user's hands when the user's arms are in a vertically
extended position. However, other heights h are also contemplated.
The load members 906a, 906b may be stationarily mounted in a fixed
position, or may be movably mounted and/or configured in a manner
that allows for adjustment to the distance d between the rings 934
and/or the height h of the rings 934 above the upper support
surface 105. Such adjustment may provided via various types and
configurations of adjustments mechanisms, and may be manually
adjustable or may be automated and controlled via the control panel
28 and an actuator, such as, for example, an electric, hydraulic or
pneumatic motor, a hydraulic or pneumatic cylinder, or any other
rotary or linear actuator that would occur to one of skill in the
art.
[0111] In one embodiment, the flexibly elastic/resilient elements
930 are configured as coil springs, which may be formed of a
metallic material or other types of elastic/resilient materials
that are capable of being elastically deformed and expanded as the
user exerts an applied force, such as a pulling force, on the rings
934, and which resiliently reforms and returns toward a contracted
or unstressed state upon release or reduction of the pulling force
on the rings 934. The coil springs 930 may be formed of any
suitable material including, for example, polymeric or plastic
materials, composite materials, metallic materials, shape-memory
materials, including polymer-based and metallic-based shape-memory
materials, or any other suitable elastic/resilient material that
would occur to one of skill in the art. As a pulling force is
applied to the rings 934, the coil springs 930 are stretched and
expanded from a first initial length l.sub.1 to a second length
l.sub.2, and contract and return toward the first initial length
l.sub.1 upon release or reduction of the pulling force.
[0112] As should be appreciated, the user stands of the upper
support surface 105 of the support base 22 and may perform any of
the exercise activities described above in association with the
exercise device 20 to provide a workout of the lower body (e.g.,
jumping rope, walking/running in place, vertical jumping, etc.).
While exercising the lower body, the user may grasp and pull on the
rings 934 of the load members 906a, 906b to simultaneously provide
a workout of the upper body. As should be appreciated, the flexibly
elastic/resilient portions 930 are expanded and are loaded as a
force is applied to the rings 934, which in turn resists movement
of the user's arms as the user pulls on the rings 934. However, in
other embodiments of the invention, the load members 906a, 906b may
be configured without the flexibly elastic/resilient portions 930,
thereby maintaining the rings 934 in a fixed position. In this
embodiment, the user may grasp the rings 934 and pull
himself/herself off of the support base 22 while performing an
exercise activity. In this manner, the weight of the user provides
loading or resistance to workout the user's upper body, which is
similar to performing chin-ups or other pull up exercises. In still
other embodiments of the invention, the flexibly elastic/resilient
portions 930 may be replaced with other types of resistance
elements, including piston-type elements which provide resistance
via an increase in fluid or air pressure as the user exerts an
applied force, such as a pulling force, on the rings 934, and with
the increased fluid or air pressure causing the resistance elements
to return toward the initial state upon release or reduction of the
pulling force on the rings 934. In other embodiments, or with one
or more weights may be attached to the ends of the cables 932 to
provide gravitational resistance. If weights are used, a guide
structure is preferably provided to guide the weights along a
predetermined vertical path.
[0113] Although the load members 906a, 906b have been illustrated
and described as having a particular configuration, it should be
understood that other configurations are also contemplated. For
example, the flexibly elastic/resilient portions or springs 930
need not necessarily be mounted to the support base 22, but may
alternatively be mounted to the vertical support 910 or to other
portions of the support structure 904. Additionally, it should be
understood that the flexibly elastic/resilient portions or springs
930 need not necessarily be mounted in a vertical orientation, but
may instead be mounted in a horizontal or angled orientation. If
the flexibly elastic/resilient portions or springs 930 are mounted
in a horizontal orientation, they may be integrated into the
support base 22. Additionally, the flexibly elastic/resilient
portions or springs 930 may be integrated with other portions of
the exercise device 900, including the vertical support column 160
and/or the support structure 904. Additionally, although the load
members 906a, 906b are illustrated as including rings 934, other
gripping devices are also contemplated for manual grasping by the
user, including various types and configurations of handles,
including devices configured similar to the ends of a jump
rope.
[0114] Referring not to FIGS. 14-19, shown therein is the exercise
device 1000 including the lower body base unit 20 and the upper
body unit 1002. As indicated above, the lower body base unit 20 is
configured similar or identical to the exercise device 20
illustrated and described above for providing a workout of the
lower body. The upper body unit 1002 is configured to provide a
simultaneous workout of the upper body, and is generally comprised
of a support structure 1004, a first load member 1006, and a second
load member 1008.
[0115] In the illustrated embodiment, the support structure 1004
generally includes a U-shaped support base 1010, a vertical support
column 1012 extending from a central region of the U-shaped support
base 1010, and a horizontal support 1014 extending transversely
from the vertical support 1012. The support structure 1004 may also
be provided with angled gussets or ribs 1016 extending from the
legs of the U-shaped support base 1010 to the vertical support
column 1012 to provide additional strength and stability to the
support structure 1004. In one embodiment, the support structure
1004 may be formed of tube steel, and may include tube portions
that are assembled together and interconnected to form a rigid
support structure. However, others types and configurations of the
support structure 1004 are also contemplated as would occur to one
of skill in the art. In one embodiment, the support structure 1004
is a stand-alone structure that need not necessarily be connected
or attached to the lower body base unit 20. In the illustrated
embodiment, the lower body base unit 20 is positioned within the
inner region of the U-shaped support base 1010, with the vertical
support column 1012 extending generally parallel with the vertical
column 160 of the lower body base unit 20. However, in other
embodiments, the support structure 1004 may be attached or
connected to the base unit 20.
[0116] In the illustrated embodiment, the lower body base unit 20
includes a number of protective panels 1018 that extend vertically
about the outer perimeter of the support base 22 and the upper
support surface 105 to prevent the user from inadvertently or
unintentionally kicking or contacting the position sensor assembly
24 and/or the adjustment mechanism 26 to prevent damage to these
devices or injury to the user. The protective panels 1018 are
formed of a transparent or translucent material that allows for the
transmission of light therethrough to avoid interfering with the
sensing capabilities of the position sensor assembly 26. The
protective panels 1018 may be supported by the support base 22, the
hand rails 500a, 500b, and/or the vertical column 160. In other
respects, the lower body base unit 20 is configured similar or
identical to the exercise device 20 illustrated and described
above.
[0117] In the illustrated embodiment, the load members 1006 and
1008 are operatively coupled to and supported by the support
structure 1004, and more specifically the vertical support column
1012. As will be discussed below, the load members 1006 and 1008
each include at least one elastic/resilient resistance element that
is capable of being elastically deformed or transitioned from an
initial state in response to exertion of an applied force, and
which resiliently reforms or transitions back toward the initial
state upon release or reduction of the applied force.
[0118] Referring now to FIGS. 16-18, in the illustrated embodiment
of the invention, the first load member 1006 generally includes a
flexibly elastic/resilient element 1020, a substantially inelastic
cable element 1022, and an actuator element or bar 1024 including a
pair of gripping portions 1026. As will be discussed in greater
detail below, a first end of the flexibly elastic/resilient element
1020 is connected to the vertical support column 1012.
Additionally, the inelastic cable element 1022 includes a first end
attached to a mid-portion of the actuator bar 1024, and an opposite
second end having a first end portion connected to the vertical
support column 1012 and a second end portion connected to the free
end of the elastic/resilient element 1020.
[0119] The gripping portions 1026 associated with the actuator bar
1024 are laterally offset from one another by a distance d (FIG.
14), which preferably corresponds to a distance equal to or
somewhat greater than the average spacing between a user's arms or
shoulders. However, other distances d are also contemplated.
Additionally, the load member 1006 is preferably configured such
that the gripping portions 1026 of the actuator bar 1024 are
positioned at a height h (FIG. 14) above the upper support surface
105 of the support base 22, which preferably corresponds to a
height of the user's hands when the user's arms are in a vertically
extended position. However, other heights h are also contemplated.
Additionally, as will be discussed below the load member 1006 and
the vertical support column 1012 include features that allow for
adjustment to the height h of the gripping portions 1026 above the
upper support surface 105 to accommodate users having different
heights or vertical reaches. In the illustrated embodiment, these
adjustment features are manually adjustable. However, automatic
adjustment features are also contemplated, with adjustment to the
height h of the gripping portions 1026 being automated and
controlled via the control panel 28 and an actuator, such as, for
example, an electric, hydraulic or pneumatic motor, a hydraulic or
pneumatic cylinder, or any other rotary or linear actuator that
would occur to one of skill in the art. In the illustrated
embodiment, the distance d between the gripping portions 1026 is
fixed. However, the actuator bar 1024 may be modified to provide
adjustment to the distance d between the gripping portions 1026 to
accommodate users having different physical attributes.
[0120] In the illustrated embodiment, the second load member 1008
generally includes a mounting element 1030, a flexibly
elastic/resilient element 1032 including first and second portions
1034a, 1034b, and a pair of gripping portions 1036 attached to the
ends of the first and second portions 1034a, 1034b. As will be
discussed in greater detail below, the mounting element 1030 is
operatively connected to the vertical support column 1012, and the
flexibly elastic/resilient element 1032 is attached to and extends
from the mounting element 1030. The lengths of the first and second
portions 1034a, 1034b of the flexibly elastic/resilient element
1032 are preferably selected such that the gripping portions 1036
are laterally offset or spread apart from one another by a distance
which preferably corresponds to a distance equal to or somewhat
greater than the average spacing between a user's arms or
shoulders. Additionally, the mounting element 1030 is preferably
coupled to the vertical support column 1012 such that the gripping
portions 1036 are positioned at a height above the upper support
surface 105 of the support base 22, which preferably corresponds to
a height of the user's hands. However, other heights are also
contemplated. Additionally, as will be discussed below, the load
member 1008 and the vertical support column 1012 include features
that allow for adjustment to the height of the gripping portions
1036 above the upper support surface 105 to accommodate users
having different heights or reaches. In the illustrated embodiment,
these adjustment features are manually adjustable. However,
automatic adjustment features are also contemplated.
[0121] Referring collectively to FIGS. 16-19, shown therein are
further details and features of the upper body unit 1002 associated
with the exercise device 1000, with the lower body base unit 20
removed for clarity. As indicated above, the upper body unit 1002
is generally comprised of a support structure 1004, a first load
member 1006, and a second load member 1008. Additionally, the
support structure 1004 generally includes a U-shaped support base
1010, a vertical support column 1012, and a horizontal support
1014.
[0122] As also indicated above, the first load member 1006
generally includes a flexibly elastic/resilient element 1020, a
substantially inelastic cable element 1022, and an actuator bar
1024 including gripping portions 1026 at either end of the actuator
bar 1024. As shown most clearly in FIGS. 17-19, the flexibly
elastic/resilient element 1020 includes a first end portion 1020a
that is operatively coupled to the vertical support column 1012,
and a second end portion 1020b that is operatively coupled to the
inelastic cable element 1022. In the illustrated embodiment, the
flexibly elastic/resilient element 1020 is configured as a flexible
or supple band or strap that is formed of an elastomeric material
capable of being stretched and elastically deformed from an initial
state to an elastically deformed state upon exertion of an applied
force, and which is also capable of resiliently reforming and
returning toward the initial state upon release or reduction of the
applied force. Such material include, for example, rubber or
rubber-like materials, latex, polymeric or plastic materials,
composite materials, metallic materials, shape-memory materials,
including polymer-based and metallic-based shape-memory materials,
or any other suitable elastic/resilient material that would occur
to one of skill in the art.
[0123] In the illustrated embodiment, each end portion 1020a, 1020b
of the band 1020 is provided with a connection device 1040. As most
clearly shown in FIG. 17, in one embodiment, the connection device
1040 includes a link 1042 attached to each end portion 1020a, 1020b
of the band 1020, and a clip 1044 connected to the link 1042. The
connection link 1040 includes a first end loop (not shown) which is
inserted through an opening in either end portion 1020a, 1020b of
the band 1020, and a second end loop which receives a looped
portion of the connection clip 1044. The connection clip 1044
includes a spring-loaded wall which may be inwardly compressed to
allow for insertion or removal of a device into the interior of the
connection clip 1044. The connection clip 1044 therefore provides a
quick and simple arrangement for releasable connecting either end
of the band 1020 to other structures or devices. Although a
particular type of connection device 1040 has been illustrated and
described for use with the band 1020, it should be understood that
other types of connection devices and connection arrangements are
also contemplated.
[0124] In one embodiment of the invention, the vertical support
column 1012 is provided with multiple attachment or connection
locations for coupling the end portion 1020a of the band 1020 and
an end portion of the inelastic cable element 1022 to the vertical
support column 1012. In the illustrated embodiment, a chain 1050 is
provided which includes multiple chain links 1052. The chain 1050
is attached to the vertical support column 1012 by way of upper and
lower mounting plates 1054. The mounting plates 1054 may be welded
or fastened to the vertical support column 1012, and the chain 1050
may be attached connected to the end plates 1054 by way of a bolt
or fastener 1056 which extends through the links 1052 at either end
of the chain 1050. As should be appreciated, the individual chain
links 1052 provide multiple attachment or connection points along a
length of the vertical support column 1012. Although a chain 1050
has been illustrated and described for providing multiple
attachment or connection locations, it should be understood that
other devices and arrangements are also contemplated as would occur
to one of ordinary skill in the art.
[0125] Referring to FIGS. 17-19, the inelastic cable element 1022
includes a first end portion is 1022a connected to the vertical
support column 1012 via the connection or attachment points
provided by the links 1052 of the chain 1050, and a second end
portion 1022b that is operatively coupled to the actuator bar 1024.
In the illustrated embodiment, the inelastic cable element 1022 is
configured as a metallic cable that is substantially inelastic to
prevent stretching or deformation when pulled to a taut state. In
one embodiment, the inelastic cable element 1022 is configured as a
multi-filament cable, such as, for example, an aircraft cable. The
inelastic cable element 1022 may include a protective sheath or
covering to minimize wear and prolong the useful life of the cable
element 1022 and the devices which come into contact the cable
element 1022. However, it should be understood that other types of
substantially inelastic elements are also contemplated for use in
association with the present invention, including non-metallic
cables or other elongate elements, such as, for example, belts,
ropes, and chains, or any other suitable elongate element that
would occur to one of skill in the art.
[0126] As shown most clearly in FIG. 17, the end portion 1022a of
the inelastic cable element 1022 includes a first cable segment
1060 that is connected or attached to one of the links 1052 of the
chain 1050, and a second cable segment 1062 that is connected or
attached to the end portion 1020b of the flexibly elastic/resilient
band 1020. As shown in FIGS. 17 and 18, the first cable segment
1060 is shown in a slacked or non-tensioned state. However, when
the user pulls on the gripping portions 1026 of the actuator bar
1024, the applied pulling force is transmitted through the
inelastic cable 1022 and stretches the flexibly elastic/resilient
band 1020. Although the flexibly elastic/resilient band 1020
provides a level of resistance to the pulling force applied to the
gripping portions 1026, the actuator bar 1024 is allowed to be
displaced in the direction of arrow A. As the actuator bar 1024 is
displaced in the direction of arrow A and the flexibly
elastic/resilient band 1020 continues to stretch, the slack in the
first cable segment 1060 is taken out until the first cable segment
1060 is transitioned to a taut or tensioned state. (FIG. 19). Due
to the inelastic nature of the cable element 1022 and the taut
state of the cable segment 1060, any additional pulling force
applied to the gripping portions 1026 will not result in any
further stretching of the elastic/resilient band 1020 or any
further displacement of the actuator bar 1024.
[0127] In the illustrated embodiment, the first and second segments
1060 and 1062 of the cable 1022 are formed as separate cables that
are interconnected or joined together via a number of clamps or
bands. However, in other embodiments, the first and second cable
segments 1060 and 1062 may be provided by a single portion of the
inelastic cable 1022. For example, the second segment 1062 of the
cable 1022 may be provided as a looped portion of the cable 1022.
Additionally, an end portion of the first cable segment 1060 is
looped back on itself to form an end loop 1064 which in maintained
by a number of clamps or bands. Similarly, an end portion of the
second cable segment 1062 is looped back on itself to form an end
loop 1066 which in maintained by a number of clamps or bands. In
the illustrated embodiment, the first cable segment 1060 is coupled
to the vertical support column 1012 by a connection clip 1070 that
passes through the end loop 1064 and a selected one of the links
1052 of the chain 1050. The connection clip 1070 may be configured
similar to the connection clip 1044 described above, or may take on
other configurations. Additionally, the second cable segment 1062
is coupled to the end portion 1020b of the flexibly
elastic/resilient band 1020 by a connection link 1072 that passes
through the end loop 1066 and the inner region of the connection
clip 1044. However, it should be understood that other types of
connection devices and connection arrangements are also
contemplated for coupling of the end portion 1022a of the cable
1022 to the vertical support column 1012 and the flexibly
elastic/resilient band 1020.
[0128] As shown in FIGS. 16, 18 and 19, the inelastic cable element
1022 runs along the upper portion of the vertical support column
1012 and is wrapped around a pair of pulleys/sheaves or eyelets
1076, 1078 mounted to the horizontal support 1014. In the
illustrated embodiment, the horizontal support 1014 includes a pair
of spaced apart plates 1080a, 1080b which define a yoke 1082 within
which the pulleys/sheaves 1076, 1078 are mounted. The end portion
1022b of inelastic cable element 1022 is coupled to a mid-portion
or central region of the actuator bar 1024 by way of a connection
link 1084 which passes through an end loop 1086 formed by the end
portion 1022b of the cable 1022 and an opening defined by a flange
or eyelet 1088 extending from a mid-portion of the actuator bar
1024. As indicated above, the actuator bar 1024 includes a pair of
gripping portions 1026 arranged at either end of the actuator bar
1024. In the illustrated embodiment, the gripping portions 1026 are
configured as handles or bars which are angled downwardly relative
to the mid-portion of the actuator bar 1024. The ends of the
handles are each provided with a spherical-shaped ball to inhibit
the user's hands from sliding off of the gripping portions 1026.
Although the gripping portions 1026 are illustrated and described
as having a particular configuration, it should be understood that
other types and configurations of gripping devices are also
contemplated for manual grasping by the user, including rings or
various types of handles that would occur to one of skill in the
art.
[0129] As indicated above, the second load member 1008 generally
includes a mounting element 1030, a flexibly elastic/resilient
element 1032 including first and second portions 1034a, 1034b, and
a pair of gripping portions 1036. The mounting element 1030 is
operatively coupled to the vertical support column 1012, the
flexibly elastic/resilient element 1032 is attached to and extends
from the mounting element 1030, and the gripping portions 1036 are
attached to each end of the flexibly elastic/resilient element
1032. As shown in FIG. 15, in the illustrated embodiment, the
mounting element 1030 is configured as a plate or block that is
releasably engagable to a generally flat mounting surface 1100
defined by the vertical support column 1012. The mounting surface
1100 may be provided with a number of openings or apertures 1102
positioned at multiple vertical locations along the height of the
vertical support column 1012. The openings or apertures 1102 are
sized to receive pins or protrusions (not shown) extending from the
mounting plate 1030 to releasably attach the mounting plate 1030 to
the vertical support column 1012 at a select height above the upper
support surface 105 of the support base 22. In order to maintain
the mounting plate 1030 in engagement with the vertical support
column 1012, the mounting plate 1030 may be provided with a magnet
(not shown), with at least the wall of the vertical support column
1012 defining the mounting surface 1100 formed of steel to
magnetically couple the mounting plate 1030 to the vertical support
column 1012. The mounting plate 1030 may also be provided with a
passage 1104 extending therethrough in a side-to-side direction and
sized to receive the flexibly elastic/resilient element 1032
therein. The passage 1104 may be provided with an open back to
facilitate lateral insertion of the flexibly elastic/resilient
element 1032 into the passage 1104 to attach the flexibly
elastic/resilient element 1032 to the mounting plate.
[0130] In one embodiment, the flexibly elastic/resilient element
1032 is provided as a single-piece strap or strand, with the first
and second portions 1034a, 1034b of the strand extending from
either side of the mounting plate 1030. However, it should be
understood that the flexibly elastic/resilient element 1032 may be
provided as separate pieces which define first and second strand
portions 1034a, 1034b. In the illustrated embodiment, the flexibly
elastic/resilient element 1032 is configured as a flexible or
supple tube or strand formed of an elastomeric material that is
capable of being stretched and elastically deformed from an initial
state to an elastically deformed state upon exertion of an applied
force, and which is also capable of resiliently reforming and
returning toward the initial state upon release or reduction of the
applied force. The flexibly elastic/resilient element 1032 may be
formed of any material that is capable of being elastically
deformed from an initial state to a deformed state, and resiliently
reformed back toward the initial state. Such materials include, for
example, rubber or rubber-like materials, latex materials,
polymeric or plastic materials, composite materials, metallic
materials, shape-memory materials, including polymer-based and
metallic-based shape-memory materials, or any other suitable
elastic/resilient material that would occur to one of skill in the
art. In the illustrated embodiment, the gripping portions 1036 have
a ring configuration. However, other gripping devices are also
contemplated for manual grasping by the user, including various
types and configurations of handles, including devices configured
similar to the ends of a jump rope.
[0131] Having described the elements and features associated with
the upper body unit 1002 of the exercise device 1000, reference
will now be made to operation and use of the lower body base unit
20 and the load member 1006 of the upper body unit 1002 by the user
according to one embodiment of the invention. As discussed in
detail above, the lower body base unit 20 includes a support base
22 defining an upper support surface 105, a position sensor
assembly 24, and adjustment mechanism 26 for adjusting the vertical
position of the position sensor assembly 24, and a control panel
28.
[0132] The lower body base unit 20 further includes a plurality of
light sources 132 (FIGS. 5-7) which light discrete portions or
regions of the upper support surface 105 to elicit a response or
activity from the user (i.e., walking, running, jumping, etc.) to
provide a workout of the lower body. The control panel 28 is in
communication with the plurality of light sources 132 and
activates/deactivates the light sources 132 to generate the
discrete lighted regions on the support surface 105. In one
embodiment, the discrete lighted regions comprise discrete light
bands extending across the support surface 105 and offset from one
another along an axis, with the control panel 28 communicating with
the light sources 132 to sequentially turn the discrete light bands
off and on in a direction along the axis to simulate a jump rope
passing beneath a user's feet. As the virtual jump rope approaches
the user, the user jumps into the air to allow the virtual jump
rope to pass beneath the user's feet.
[0133] In another embodiment, the discrete lighted regions comprise
at least two discrete zones of light, with the first light zone
extending over a left half of the support surface 105 and the
second light zone extending over a right half of the support
surface 105, and with the control panel 28 communicating with the
light sources 132 to activate and deactivate the light zones. As
the light zones are activated/deactivated, the user is cued or
prompted to raise or lower his or her foot corresponding to the
activated/deactivated light zone. It should be understood that the
control panel 28 may be programmed to activate/deactivate the light
sources 132 in a manner which lights other discrete portions or
regions of the upper support surface 105 to elicit other user
responses or activities to provide a workout of the lower body.
[0134] As also discussed above, the position sensor assembly 24
includes at least two position sensors 202 (FIGS. 1-6) having
sensing paths that are arranged along a sensing plane relative to
the upper support surface 105, and with the control panel 28
communicating with the position sensors 202 to detect the presence
of the user along the sensing plane. The position sensor assembly
24 may therefore be used to provide real time feedback to the user
to verify the user's performance of various user activities,
including walking or running in place, jumping over a virtual jump
rope, or any other lower body activity that would occur to one of
skill in the art.
[0135] While performing an activity on the base unit 20 to work out
the lower body, the user may also grasp the gripping portions or
handles 1026 of the actuator bar 1024 and exert an applied force,
such as a pulling force, onto the actuator bar 1024 to
simultaneously work out the upper body. As the user pulls down on
the actuator bar 1024 in the direction of arrow A (or in other
directions), the applied force is transmitted through the inelastic
cable 1022, which in turn stretches and elastically deforms the
elastic/resilient band 1020. Upon release or reduction of the
applied force to the gripping portions 1026, the elastic/resilient
band 1020 resiliently reforms and returns toward the initial state.
As should be appreciated, as the user progressively applies a
pulling force onto the gripping portions 1026, the
elastic/resilient band 1020 continues to stretch and resistance to
the applied pulling force correspondingly increases. In other
words, the resistive force generated by the elastic/resilient band
1020 increases as the user continues to pull down on the gripping
portions 1026. Additionally, as the pulling force is applied to the
gripping portions 1026, the elastic/resilient band 1020 is
stretched from a first initial length l.sub.1 to a second length
l.sub.2, which permits displacement of the actuator bar 1024 in the
direction of arrow A or in other directions to the position shown
in FIG. 19. Upon release or reduction of the pulling force on the
gripping portions 1026, the elastic/resilient band 1020 resiliently
reforms and returns toward the first initial length l.sub.1, which
in turn displaces the actuator bar 1024 in an upward direction
opposite arrow A to the initial position shown in FIG. 18.
[0136] As shown most clearly in FIG. 17, when the elastic/resilient
band 1022 is in the initial, non-stretched state (with the actuator
bar 1024 in the initial position shown in FIG. 18), the cable
segment 1060 of the inelastic cable element 1022 is in a slackened
or non-tensioned state. In the slackened or non-tensioned state,
the cable segment 1060 permits stretching and elastic deformation
of the band 1020 in response to application of a pulling force onto
the gripping portions 1026. Stretching of the band 1020 allows
displacement of the actuator bar 1024 in the direction of arrow A,
which in turn allows downward displacement of the user's hands and
arms as the user applies a downward force onto the gripping
portions 1026. Progressively increasing the pulling force applied
to the gripping portions 1026 continues to stretch the band 1020,
which results in removal of the slack from the cable segment 1060.
Once the slack in the cable segment is completely removed, the
cable segment 1060 is transitioned to a tensioned or taut state,
which prevents further stretching and elastic deformation of the
band 1020. The cable segment 1060 therefore functions as a blocking
element to limit stretching and elastic deformation of the band
1020 to a predetermined level. The cable segment 1060 also prevents
overstretching of the band 1020, which could otherwise result in
failure of the band 1020 and potential injury to the user.
[0137] When the cable segment 1060 is in the slackened or non-taut
state, application of a pulling force onto the gripping portions
1026 allows stretching and elastic deformation of the band 1020.
However, once the cable segment is transitioned to the taut state,
the cable segment 1060 will prevent further stretching and elastic
deformation of the band 1020 beyond the predetermined level of
deformation. At this point, any additional pulling force applied to
the gripping portions 1026 will not result in further displacement
of the actuator bar 1024, and the user's hands and arms will be
maintained in position, even as the user continues to apply a
downward pulling force onto the gripping portions 1026. As a
result, the user may pull himself/herself off of the support
surface 105 of the support base 22 while performing an exercise
activity. In this manner, the weight of the user provides loading
or resistance to workout the user's upper body, which is similar to
performing chin-ups or other pull up exercises.
[0138] Although the cable segment 1060 has been illustrated and
described as a blocking element to limit stretching and elastic
deformation of the band 1020 to a predetermined level, it should be
understood that other features may be included to limit stretching
and elastic deformation of the band 1020 to a predetermined level.
For example, a block could be attached to the vertical support
column 1012 or the horizontal support 1014, and a stop element
could be attached to the inelastic cable 1022. As should be
appreciated, application of a pulling force onto the gripping
portions 1026 would allow stretching of the band 1020 and
displacement of the actuator bar 1024 until the stop element abuts
the block attached to the vertical support column 1012 or the
horizontal support 1014. Such abutment would in turn prevent
further stretching and elastic deformation of the band 1020, and
thereby limit stretching and elastic deformation of the band 1020
to a predetermined level. As should also be appreciated, the
position of the block and/or the position of the stop element could
be varied to corresponding vary the point at which the stop element
abuts the block, which would in turn adjust the predetermined level
of stretching and elastic deformation of the band 1020.
[0139] As indicated above, the links 1052 of the chain 1050 provide
multiple points of attachment for connecting the end portion 1022a
of the band 1020 and the free end of the cable segment 1060 to the
vertical support column 1012. As should be appreciated, connection
of the end portion 1022a of the band 1020 to a select one of the
chain links 1052 correspondingly positions the gripping portions
1026 of the actuator bar 1024 at a select height h above the
support surface 105 (FIG. 14). As should also be appreciated, the
height h of the gripping portions 1026 may be varied by connecting
the end portion 1022a of the band 1020 to a different chain link
1052. In this manner, the height h of the gripping portions 1026
may be selected to correspond to the particular height or vertical
reach of the user. Additionally, connection of the free end of the
cable segment 1060 to a select one of the chain links 1052
correspondingly determines the lowest position or height of the
gripping portions 1026 of the actuator bar 1024 when the cable
segment 1060 is transitioned to the tensioned or taut state shown
in FIG. 19. As should be appreciated, the lowest position of the
gripping portions 1026 may be varied by connecting the free end of
the cable segment 1060 to a different chain link 1052.
[0140] Although the illustrated embodiment of the upper body unit
1002 utilizes a single elastic/resilient element 1020, it should be
understood that two or more elastic/resilient elements 1020 may be
coupled between the vertical support column 1012 and the inelastic
cable 1022 to provide variable levels of resistance to the pulling
force applied to the gripping portions 1026 by the user.
Additionally, it should be understood that a set of
elastic/resilient elements 1020 having different levels of
elasticity may be provided for use in association with the upper
body unit 1002, with one of the elastic/resilient elements 1020
selected to provide a particular level of resistance to the pulling
force applied to the gripping portions 1026. Furthermore, although
the elastic/resilient element 1020 illustrated and described above
is configured as a flexible band or strap, it should be understood
that other types of elastic/resilient elements are also
contemplated for use in association with the upper body unit 1002.
For example, in one alternative embodiment, the elastic/resilient
element 1020 may be configured as a spring, such as a coil spring,
that is expanded upon application of a pulling force onto the
gripping portions 1026. In another alternative embodiment, the
elastic/resilient element 1020 may be configured as a flexible rod
or bar that is bent or flexed to an arcuate configuration upon
application of a pulling force onto the gripping portions 1026. In
a further alternative embodiment, the elastic/resilient element
1020 may be configured as a piston-type element which provides
resistance via an increase in fluid or air pressure as the user
exerts a pulling force onto the gripping portions 1026, with the
increased fluid or air pressure causing the resistance elements to
return toward an initial state upon release or reduction of the
pulling force. In another alternative embodiment, one or more
weights may be attached to the cable 1022 to provide gravitational
resistance to a pulling force applied to the gripping portions
1026. If weights are used, a guide structure is preferably provided
to guide the weights along a predetermined vertical path.
[0141] While the invention has been illustrated and described in
detail in the drawings and foregoing description, the same is to be
considered as illustrative and not restrictive in character, it
being understood that only the preferred embodiments have been
shown and described and that all changes and modifications that
come within the spirit of the invention are desired to be
protected.
