Description
BACKGROUND OF THE INVENTION
[0001] 1. The Field of the Invention
[0002] The present invention relates to exercise equipment such as
exercise cycles that simulate the action of pedaling a bicycle.
[0003] 2. The Prior State of the Art
[0004] Exercisers who wish to keep physically fit without venturing
outside can use a vast array of exercise equipment to augment or
provide physical workouts. One of the most popular of these
exercise devices is the stationary exercise bicycle, because it
provides the exerciser with a thorough low-impact aerobic
workout.
[0005] Early exercise bicycles were real bicycles mounted on stands
that prevented the wheels from contacting the ground while the
exerciser pedaled. Modern sophisticated bicycle-simulating
equipment includes bicycle cranks movably coupled to a flywheel to
provide resistance to the pedal motion driven by the feet of the
exerciser. Some of these modern exercise devices resemble standard
bicycles and provide similar physical benefits. For example,
recumbent exercise bicycles provide many of the same physical
benefits of exercise on standard bicycles.
[0006] One of the significant problems with modern
bicycle-simulating exercise equipment, such as spinner bicycles, is
the traditionally stoic and rigid nature of spinner devices. These
exercise devices are typically non-responsive to the extra workout
efforts of the operator. To minimize these problems, bicycle
simulating exercise equipment utilizes various performance
enhancements to more accurately simulate a bicycle ride. For
example, some bicycle-simulating equipment alters the crank
resistance according to a virtual bicycle path so that the workout
resembles hills and mountains.
[0007] Another example is a bicycle-simulating device, which
includes a large base pedestal with four resilient rubber feet that
support the pedestal about four inches above the floor. The rubber
feet are spaced around the periphery of the pedestal at
approximately 90-degree intervals. During exercise use, the
resilient rubber feet allow the cycle to rock in a circular motion
along with the movement of the exerciser. One problem with this
design, however, is the increased wear with each rubber foot that
is caused by continual contact with the support surface. This
circular motion can also result in sufficient instability in the
device that may cause the device to tip over.
SUMMARY AND OBJECTS OF THE INVENTION
[0008] It is therefore an object of the present invention to
provide an improved exercise device.
[0009] It is another object of the present invention to provide an
improved exercise cycle.
[0010] It is another object of the invention to provide a moving,
flexible coupler that couples an upright member of an exercise
system to a base.
[0011] It is another object of the present invention to provide an
exercise cycle with lateral movement.
[0012] The present invention relates to exercise equipment that
allows lateral (e.g., side to side) movement while the operator is
exercising, so as to more accurately simulate the dynamic of side
to side movement. The present invention provides an exercise
mechanism flexibly coupled to a support base in a convenient and
efficient manner such that the coupling allows lateral movement and
other movements made during exercise without compromising base
stability. One embodiment of this particular invention is drawn to
any stationary exercise cycle that is supported by an upstanding
support extending up from a base (e.g., a platform) that rests upon
the floor. The stationary exercise cycle of the present invention
allows for a more natural exercise experience by enhancing the
natural bicycle movements on the stationary bicycle frame. Allowing
the stationary exercise frame to move laterally in a side-to-side
motion generates such natural bicycle movement.
[0013] This improved exercise system may be part of a virtual
exercise system that provides a sensory environment compatible with
the cycling activity via a media interface.
[0014] Accordingly, one advantage provided by the stationary
exercise cycle of the present invention is that it allows for a
more natural exercise experience by enhancing available natural
bicycle side to side movements on the stationary structure. The
exercise cycle of the present invention is responsive to the extra
workout efforts of an exerciser, such as side to side movements, by
providing lateral motion of the upstanding support structure.
Further, the exercise system may be adjusted to accommodate for
various operator attributes, such as height and weight that produce
performance inconsistencies with existing exercise equipment.
[0015] Another advantage of the present invention is the use of an
integrated virtual cycling-type exercise system for an improved
motivational stationary exercise device. The exercise system
advantageously provides wireless or network communication with
other external networks or communication systems, such as iFit.com,
to allow data and other information to be shared or exchanged with
the virtual exercise system. The virtual exercise system uses a
visual display and a media component to enhance the operator's
workout experience. In one configuration, the virtual exercise
system is responsive to the lateral movements of the exercise cycle
creating a synchronous sensory workout experience. Exemplary visual
display devices include but are not limited to wide screen glasses,
an LCD screen affixed to the frame, and/or a large LCD screen or
projection TV. Exemplary media components include DVD, VHS,
streaming video, iFit.com exercise session, and/or other media
performance medium.
[0016] This improved virtual exercise system provides the operator
with a wider variety of motivation. For example, in a simulated
Tour de France, the operator is allowed to participate in the
preliminary, hill climbing, sprints, and other stages. As operators
compete, they begin turning the cranks with greater force, moving
the virtual cycle with greater force than normal and as with normal
cycling, this results in greater lateral movement. In the
responsive configuration, this additional movement is reflected on
the visual display with the view rocking with the bicycle. Yet
another configuration would alter the playback of the course
displaying the course at a rate corresponding to the operator's
efforts. The audio media can also reflect a sound speed increase or
decrease to reflect what a cyclist traveling at the operator's
virtual speed would hear.
[0017] An alternative configuration appeals to the participants of
spinning classes because it allows every operator to finish the
course at the same time regardless of how much work they have done
individually during the class. This allows operators of various
abilities to work together without competing directly with each
other.
[0018] The present invention also relates to a variety of other
exercise mechanisms in addition to exercise cycles that can be
coupled to an upstanding member movably coupled to a support
base.
[0019] Additional objects and advantages of the invention will be
set forth in the description which follows, and in part will be
obvious from the description, or may be learned by the practice of
the invention. The objects and advantages of the invention may be
realized and obtained by means of the instruments and combinations
particularly pointed out in the appended claims. These and other
objects and features of the present invention will become more
fully apparent from the following description and appended claims,
or may be learned by the practice of the invention as set forth

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0033] FIG. 1 and the following discussion are intended to provide
a brief, general description of a suitable exercise environment in
which the invention may be implemented. FIG. 1 demonstrates an
embodiment of an exemplary cycling-type exercise system 8. FIG. 1
is intended to be illustrative of a system 8 that may utilize the
present invention and is not to be construed as limiting. Exercise
system 8 can move in a natural lateral motion without adversely
affecting the reliability and stability of the system during a
workout. Exercise system 8 illustrates a cycling-type exercise
device having a base 10, an upstanding support member 12, and a
flexible coupler 13 flexibly coupling base 10 to member 12.
Flexible coupler 13 is configured to allow lateral motion of
upstanding support member 12 when the operator engages in side to
side movement.
[0034] Base 10 can have a variety of different configurations, as
will be appreciated by one skilled in the art in light of the
disclosure herein. Base 10 as shown in FIG. 1 comprises a central
support member 15 and front and back elongate members 22, 24
coupled thereto. Central support member 15 comprises a front beam
17a, a rear beam 17b, and a plate 18, coupling front beam 17a to
rear beam 17b. A variety of other means may be employed for
coupling front beam 17a to rear beam 17b. Thus, base 10 may be
constructed in a variety of fashions, so long as the design
maintains overall stability for the exercise device and reliability
with regards to the coupling.
[0035] The base components are configured such that an operator
exercising on the device will not tip the spinning cycle over--even
during side to side (or front to back) movement. In one
configuration, the elongate members 22, 24 extend at least to the
farthest point of potential lateral movement from the upstanding
member 12. It is further anticipated that in one embodiment, the
lateral movement will not exceed about 20 degrees in both
directions, and may be limited to about 10 degrees, for example.
Although configurations exist in which the lateral movement is
extended even further, this range of motion is generally
unnecessary to simulate bicycle exercise. As a general rule, the
design of the support base is based in part on the allowed lateral
movement of the exercise device and the expected force to be
exerted by an operator in this position.
[0036] In the embodiment of FIG. 1, flexible coupler 13 comprises a
pivot tube 14 pivotally coupled to base 10, dampening wings 16
coupled to the pivot tube 14, and dampening inserts 20 on opposing
sides of pivot tube 14. The dampening inserts are preferably an
elastomeric material, such as a resilient urethane insert, but may
be any material which diminishes the movement of the upstanding
support structure via compression and/or tension of the insert by
the wings and base. Flexible coupler 13 thus allows upstanding
support member 12 to remain stably coupled to base 10, while
nevertheless enabling natural lateral bicycle movements of
upstanding support member 12. It will be understood by those of
ordinary skill in the art in light of the disclosure herein that
modifications can be made concerning the dampening mechanism while
remaining within the scope of the present invention.
[0037] In the embodiment of FIG. 1, upstanding member 12 extends
forwardly and slightly upwardly from base 10 and coupling 13,
enabling the seat support beam to position the seat support post
and seat roughly above the coupling.
[0038] In the embodiments shown in FIG. 1, upstanding support
member 12 has an exercise mechanism coupled thereto that allows the
user to exercise his or her body. In the embodiment of FIG. 1, the
exercise mechanism comprises a seat support beam 33 having seat 34
coupled thereto. Seat support beam 33 has a telescoping extension
member 39 therein to which seat support post 37 is slidably
coupled. The horizontal position of seat support post 37 relative
to seat support beam 33 is selectively locked in place by a pin 36
mounted within beam 33 and spring biased into engagement with one
of a series of holes formed in telescoping extension member 38. The
head of pin 36 is formed into a knob that aids in grasping the pin
to pull it back against the spring bias when it is desired to
change the barrel extension position.
[0039] Seat 34 is mounted on the seat support post 37 and the
height of the seat relative to the base 10 can be adjusted through
the use of pin 38 coupled to extension member 39 and spring biased
into engagement with one of a series of holes formed in the seat
support post 37. As with pin 36, the head of pin 38 is formed into
a knob that aids in grasping the pin to pull it back against the
spring bias when it is desired to change the seat position.
[0040] In addition to the seat structure, the exercise mechanism of
FIG. 1, futher comprises bicycle-type cranks 25 movably coupled for
rotation on opposing sides of upstanding member 12, the cranks
being rotatable about a first axis so that the bicycle cranks
rotate in the typical bicycle fashion. Pedals 27 are coupled to
respective cranks on opposing sides of member 12. Cranks 25 with
pedals 27 thereon can support a user above a support surface as the
user places his or her feet on the pedals 27.
[0041] Flywheel 28 is also coupled to upstanding member 12 and is
rotatable about a second axis, which is parallel to the first axis.
The bicycle-type cranks 25 are movably coupled to the flywheel 28,
such as through the use of a drive mechanism. In one embodiment of
the exercise device of the present invention, the drive mechanism
comprises a direct gear drive that does not use a chain. This
allows the exercise device to have a smaller footprint so the
flywheel can be placed closer to the cranks. In another embodiment,
however, the drive means uses a chain to couple the flywheel and
cranks. By placing the flywheel behind the crank, a more natural
lateral motion is generated via a gyroscopic motion caused by
rotation of the flywheel on the flexibly coupled upstanding support
member.
[0042] The exercise mechanism of FIG. 1 further comprises a
handlebar 30 mounted on a handlebar support post adjustably coupled
to upstanding member 12. The vertical position of the handlebar
support post and thus handlebar 30 is locked in place by a pin
mounted within member 12 and spring biased into engagement with one
of a series of holes formed in the handlebar support post. The pin
32 is spring biased into engagement with the holes in the handlebar
support post. As with pins 36 and 38, the head of pin 32 is
preferably formed into a knob that aids in grasping the pin to pull
it back against the spring bias when it is desired to change the
handlebar position.
[0043] A media display device 35 may optionally be affixed to the
exercise machine, such as to the handlebar support post. Device 35
may be positioned as shown in FIG. 1 or may be moved downwardly
toward member 22 such that a user can comfortably view device 35
while leaning toward handlebar 30.
[0044] Device 35 may include part of an improved motivational
integrated virtual cycling-type exercise system, such as the
display portion, for example. The integrated exercise system
advantageously provides wireless or network communication with
other external networks or communication systems, such as iFit.com,
to allow data and other information to be shared or exchanged with
the virtual exercise system. The virtual exercise system uses a
visual display and a media component to enhance the operator's
workout experience. In one configuration, the virtual exercise
system is responsive to the lateral movements of the exercise cycle
creating a synchronous sensory workout experience. Exemplary visual
display devices include but are not limited to wide screen glasses,
LCD screen affixed to the frame, Large LCD screen or projection
TV.
[0045] Exemplary media components include DVD, VHS, streaming
video, iFit.com exercise session, or other media performance
medium. This virtual exercise system is discussed in more detail in
U.S. patent application Ser. No. 09/349,608 (SYSTEMS AND METHODS
FOR PROVIDING AN IMPROVED EXERCISE DEVICE WITH MOTIVATIONAL
PROGRAMMING, to Watterson, et al., filed Jul. 8, 1999); Ser. No.
09/641,627 (SYSTEM FOR INTERACTION WITH EXERCISE DEVICE, to
Watterson, et al., filed Aug. 18, 2000); Ser. No. 09/641,600
(COMPUTER SYSTEMS AND METHODS FOR INTERACTION WITH EXERCISE DEVICE,
to Watterson, et al., filed Aug. 18, 2000); and Ser. No. 09/641,220
(SYSTEMS AND METHODS FOR INTERACTION WITH EXERCISE DEVICE, to
Watterson, et al., filed Aug. 18, 2000), each of which are
incorporated herein by reference. It will be understood by those of
ordinary skill in the art and others that certain modifications can
be made concerning the virtual exercise system while remaining
within the scope of the present invention. For example, the media
display device may be remotely affixed, such as through a wall
mounting. In fact, one configuration allows multiple bicycles to
use a single large media display system. Another acceptable
configuration uses VR media glasses worn by the operator to provide
a media playback consistent with the operators activities on the
exercise device.
[0046] In one embodiment, the virtual cycling-type exercise system
comprises a sensor coupled on or adjacent to the crank 26 and/or
flexible coupler 13 (e.g., embedded within, below, or above the
dampening insert), such as a reed switch, for example, such that
the virtual system can monitor the amount of movement of one or
more moving parts, such as the lateral movement of coupler 13, for
example. Optionally, the virtual system is configured to control
one or more parts.
[0047] Thus, one embodiment of the present invention is a virtual
exercise system comprising: (i) a stationary exercise cycle 8 that
allows for natural lateral movement, the exercise cycle 8
comprising a base 10 that rests on the floor, an upstanding support
12 extending from the base 10, and a flexible coupler 13 that
couples the base 10 to the upstanding support structure 12 so that
the upstanding support structure 12 moves in a lateral motion
responsive to cycling efforts of an operator; (ii) a visual
display; and (ii) a media interface electrically coupled to the
visual display, the media interface providing a conduit for media
information to be relayed to the visual display and the
operator.
[0048] The virtual exercise system can be responsive in part to the
lateral motion of the stationary exercise cycle 8 and in part to
the cycling efforts of an operator, for example. The display (e.g.,
display 35) can further comprise an audio speaker. The media
interface can further provide motivational music or other messages
to enhance the operator's workout. In one embodiment, the visual
display is a motivational visual display following the course of an
actual bicycle ride to assist the operator in simulating a bicycle
ride.
[0049] Thus in one embodiment, the system of FIG. 1 comprises a
virtual exercise system that provides a sensory environment
compatible with cycling activity via a media interface. The media
interface may comprise a visual and/or an audio display device
based in part on the movements of the exercise system 8. The
virtual exercise system may comprises a communication connection to
an external network to supply data for the sensory environment, for
example, such as an internet based system. The communication
connection may be a wireless connection between the exercise system
and the external network, for example.
[0050] As discussed, the embodiment shown in FIG. 1 provides an
exercise system that simulates the action of a bicycle while
remaining stationary. However, those skilled in the art will
appreciate that the invention may be practiced with many types of
exercise mechanisms, including spinner, recumbent, bicycle,
tricycle, or treadmill devices, climbers, stair steppers,
multi-function exercise systems, arm exercise systems, for example,
and other exercise mechanisms. Such exercise mechanisms can be
coupled to the flexible coupler 13 in a manner that allows these
mechanisms to be flexibly coupled to a stable base.
[0051] Reference is next made to FIG. 2, which demonstrates: (i) a
cross sectional view of plate 18 of base 10; (ii) upstanding member
12; and (iii) flexible coupler 13 for coupling base 10 to
upstanding member 12. Pivot tube 14, first and second opposing
dampening inserts 20a, 20b, and first and second dampening wings
16a, 16b of flexible coupler 13 are shown. Upstanding member 12 and
dampening wings 16a and 16b are affixed to pivot tube 14 such that
they move in unison according to the lateral force exerted by an
operator.
[0052] With continued reference to FIGS. 2 and 3, flexible coupler
13 further comprises an axle 19 coupled to base 10 above plate 18
of base 10. Pivot tube 14 is movably coupled to axle 19 such that
as pivot tube 14 pivots, upstanding member 12 is moved laterally,
i.e., in a side to side motion. Proximal and distal bushings 15 may
be mounted between pivot tube 14 and axle 19. As shown, axle 19 is
coupled to respective upstanding walls of opposing front and rear
beams 17a, 17b above plate 18 and, in one embodiment is parallel to
the central support beam 15, enhancing the stability of the system.
Consequently, opposing spaces exist between dampening wings 16a and
16b and respective sides of plate 18.
[0053] Dampening inserts 20a and 20b fill the spaces between the
dampening wings (16a and 16b) and plate 18. Dampening inserts 20a,
20b ensure that the side to side movement of upstanding member 12
is gradually stopped, rather than being stopping in a sudden,
halting motion. The dampening inserts of the present invention act
as cushioning members. The inserts 20a, 20b also dissipate the
lateral forces before the exercise device is moved into an unstable
state.
[0054] Dampening inserts 20a, 20b preferably comprise an
elastomeric, urethane-based material. Other insert compositions,
known to one skilled in the art, are considered within the scope of
the present invention including rubber, gel packs, bungee cords or
other elastic members, air modules, springs, and other compressible
inserts, for example. Dampening inserts 20a, 20b may be coupled to
plate 18 and wings 16a, 16b via means for coupling known to one
skilled in the art, including via slots, grooves, removable
Velcro.RTM. tabs, adhesive(s), bolts, or other suitable means for
coupling the inserts between the dampening wings and the base plate
18. Such means for coupling may include means for removably
coupling the dampening inserts to the base and/or wing(s), such as
selectively removable hook and pile (e.g., VELCRO) tabs on the wing
and/or base and one or may dampening insert(s) for example.
[0055] In one embodiment, only one of the two inserts is being
compressed in any operational position. However, one configuration
places both inserts under compression when the upstanding member 12
is in the substantially vertical position so that the upstanding
support member 12 self-corrects its alignment to the substantially
vertical position when there are no forces introduced by the
operator. For example, both inserts 20a, 20b can be configured to
be slightly compressed when upstanding member 12 is in a
substantially vertical position such that member 12 is retained in
the vertical position unless a user moves member 12 to one
direction or another. Thus, the upstanding support member can be
configured to remain in the substantially vertical position in the
absence of a force introduced to move the upstanding member from
the substantially vertical position. This configuration also
contributes to a more natural riding experience as a bicycle in
motion traditionally defaults to a more stable substantially
vertical alignment.
[0056] Yet another advantage of using the dampening inserts is that
they may be optimized for the operator. For example, a heavy
operator will exert greater force on the exercise device making the
cycle move laterally with less exercise. To some degree, the extra
weight may be mitigated through the use of a more rigid dampening
insert.
[0057] Thus, one example of a means for adjusting the flexibility
of the coupler 13 of the present invention comprises one or more
removable dampening inserts that may be replaced with inserts
having greater or lesser flexibility. Hook and pile material, such
as VELCRO, may be employed to selectively mount the removable
dampening inserts between the base and dampening wing(s) of the
present invention, for example, as mentioned above.
[0058] FIGS. 4a and 4b illustrate the dampening inserts in both
compression and tension states when the upstanding support
structure is rotated to opposing sides. In this embodiment, the
dampening inserts are physically attached to the dampening wings
and base 10, thereby allowing the dampening inserts to contribute
counter-force in both the compression and tension positions. The
compression and tension positions occur when upstanding support
structure 12 is rotated around the axis of axle 19 from a
substantially vertical position into a flexed position.
[0059] For example, in FIG. 4a, dampening insert 20b is being
compressed while dampening insert 20a is being extended. FIG. 4b
illustrates dampening insert 20a under compression and dampening
insert 20b is under tension. When the dampening inserts are not
physically attached to both the wings and the base, they only
substantially contribute to compression forces.
[0060] In yet another embodiment, only a single dampening insert is
employed and is coupled both to the base plate and a dampening
wing. In this embodiment, when upstanding member 12 is moved toward
the single dampening insert, the insert compresses until the
movement is stopped. When the upstanding member 12 is moved away
from the single dampening insert, the insert extends until the
movement is stopped. Thus, the dampening effect of a single or
multiple inserts can be achieved both through compression and/or
extension of the dampening insert.
[0061] With reference now to FIGS. 5 and 6, another example of a
flexible coupler 48 of the present invention will be described.
Coupler 48 flexibly, movably couples upstanding member 12 to a
support base 10a. Coupler 48 comprises a block 58 that is movably
coupled to a dual arcuate slotted base 10a. Upstanding member 12 is
affixed to block 58 (e.g., by being directly coupled to an arcuate
member 54, which is coupled to block 58, or, in another embodiment,
by being directly coupled to block 58). First and second axles 56
extend through block 58 and arcuate slots 50 of base 10a and are
movably coupled to base 10a by fastening mechanism 52, such as a
nut or rivet, as shown in FIG. 6.
[0062] Axles 56 extending through block 58 move upwardly and
downwardly within respective arcuate slots 50 in base 10a as a user
moves in a side to side motion. One axle moves upwardly within a
respective slot 50 while the other moves downwardly. The dual
arcuate slotted walls 17a, 17b of base 10a enable these
side-to-side motions.
[0063] In the embodiment of FIG. 6, dampening inserts 60a and 60b
are mounted between moving block 58 and base plate 18a of base 10a.
Dampening inserts 60a and 60b restrict the side to side motion of
upstanding member 12 through compression and/or tension of the
dampening inserts. Dampening inserts 60a, 60b may be in tension
and/or compression, depending upon a desired embodiment and
depending upon the movements of a particular user. The dampening
inserts are preferably made from urethane, but may comprise other
dampening materials as known to one of skill in the art. Axles 56
can extend through dampening inserts 60a, 60b or may be mounted
beside inserts 60a, 60b, for example.
[0064] In another embodiment, slots 50 are configured to allow
front to back and/or side to side movement, such as by having an
oval shape with sufficient space for axles 52 to move front to back
and side to side. In this embodiment, there is sufficient space
between block 58 and walls 17a, 17b to allow for front to back
movement.
[0065] FIG. 7 is a cross sectional view of a configuration of an
alternate flexible coupler 60 of the present invention comprising a
single dampening insert 80. Coupler 60 further comprises a single
dampening wing 64 coupled to upstanding member 12. Dampening insert
80 fills the space between dampening wing 64 and plate 18 of base
10 (see FIG. 1). This configuration enables front to back and
side-to-side motion according to the forces generated by the
operation of the exercise device. Structure 54 transfers the
operational forces across the dampening wing 64. Insert 80 is
preferably made from a durable and compressible material, such as
urethane. Other insert compositions, known to one skilled in the
art, are considered within the scope of the present invention
including rubber, other elastomeric materials, gel packs, air
modules, springs, and other compression inserts. As with the
previous configurations, the insert 80 may be affixed to the
dampening wing 64 and/or base plate 18 via means known to one of
skill in the art, including via slots, grooves, removable
Velcro.RTM. tabs, adhesives, bolts, or other suitable means to
affix the inserts between the dampening wings and base. An
alternative configuration prevents the upstanding support member
from front to back motion.
[0066] FIGS. 8a and 8b are cross sectional views illustrating
lateral motion of the exercise system in both compression and
tension states when upstanding member 12 is rotated to opposing
sides of the device. The movement of upstanding member 12
translates to substantial movement at the seat and handlebars of
the exercise system. In this configuration it is preferable for
insert 80 to be affixed to dampening wing 64 in a manner that
enables dampening insert 80 to be under tension and compression.
FIG. 8a illustrates one side 80b of insert 80 under compression and
an opposing side 80a under tension. FIG. 8b illustrates side 80a
under compression and side 80b under tension. Another configuration
places the entire insert under compression so that when the
upstanding support member reaches the maximum lateral motion from
vertical, the insert on the opposite side is uncompressed.
[0067] With reference now to FIGS. 9 and 10, yet another embodiment
of a flexible coupler 90 of the present invention comprises: (i) a
pivot tube 14 movably coupled to an axle 17; (ii) first and second
dampening wings 16a, 16b coupled to pivot tube 14; and (iii) first
and second dampening inserts in the form of springs 40a, 40b
coupled to respective dampening wings 16a, 16b. Axle 17 and bushing
15 allow lateral motion of upstanding support member 12. The
configuration of coupler 90 can be similar to that previously
described in association with FIG. 2 with the notable exception
that calibrated springs 40a, 40b are used in place of the dampening
inserts shown in FIG. 2. Specifically, springs 40a and 40b are
placed between base plate 18 and the dampening wings 16a and
16b.
[0068] One or more springs can be removable such that springs
having differing compression and extension capabilities can be
employed. Such removable springs are additional examples of means
for adjusting the flexibility of the coupler. Another example of a
means for adjusting the flexibility of a coupler comprises a screw
that is selectively threaded within the spring along the contours
of the spring to thereby decrease the flexibility of the spring. In
one configuration, an elastomeric membrane is placed between the
wings and the base plate to prevent exposure of the springs to
fingers, toes, or other objects during exercise.
[0069] Axle 19 is mounted on base 10 so that pivot tube 14 may
freely rotate about a horizontal axis substantially parallel to the
central support beam. Pivot tube 14 surrounds the bushing 15 and is
affixed to pivot wings 16a, 16b. The axle 19 holds pivot tube 14
above base plate 18, enabling free lateral rotation about axle
19.
[0070] A row of calibrated springs 40 are placed on opposing sides
of pivot tube 14 between the base plate 18 and wings 16a, 16b. As
with the dampening inserts of FIG. 2, inserts in the form of
springs 40 may either be slightly compressed or uncompressed in the
default or resting state. If both sides are slightly compressed in
the neutral, resting state, upstanding support member 12 is
centered under the forces of the springs. Thus, in one embodiment,
both sides are slightly compressed in the resting state in order to
place upstanding member 12 in the neutral position. The wings 16
and base plate 18 provide stable surfaces for the springs to exert
force against when the support structure moves laterally.
[0071] FIGS. 11a & 11b are cross sectional views illustrating
the lateral motion of the upstanding support structure relative to
the springs. As with other dampening inserts, various
configurations may use the springs 40a, 40b in both a state of
compression and tension. For example, FIG. 1 a illustrates springs
40a in tension and springs 40b in compression. FIG. 11b illustrates
springs 40b in tension and springs 40a in compression. Acceptable
alternative configurations as known to one of skill in the art
include a configuration in which springs located on both sides of
the exercise devise are kept compressed within the acceptable
operational range. In some configurations the compression is
physically limited to lateral rotation of about ten degrees on
either side from a substantially vertical position into a flexed
position.
[0072] FIGS. 12 and 13 show additional embodiments of flexile
couplers 100, 110 respectively of the present invention that
flexibly couple upstanding member 12 to a support base, such as
base 10. Each of these flexible couplers include means for
adjusting the flexibility of the coupler.
[0073] Flexible couplers 100, 110 are adjustable such that the
amount of lateral movement achieved by a user can be selectively
adjusted. For example, the flexibility of the flexible coupler 100
of FIG. 12 can be adjusted by selectively turning one or more knobs
102a, 102b to adjust the amount of compression of one or both sides
of dampening insert 80x. By compressing one or more of the sides of
dampening insert 80x, the flexibility of the side(s) is decreased.
For example, by twisting knob 102a further downward onto post 104a,
and/or by twisting knob 102b downward onto post 104b, dampening
insert 80x is compressed and thereby becomes less flexible on both
sides.
[0074] Similarly, by twisting knobs 112a, 112b coupled to inserts
20c, 20d, the flexibility of inserts 20c, 20d and hence the lateral
movement potential of coupler 110 is adjusted. Insert 20c is shown
in FIG. 13 as being adjusted to the compressed position. Thus,
knobs 102a, 102b and knobs 112a, 112b and their respective
associated threaded posts are each examples of means for adjusting
the flexibility of their respective couplers.
[0075] Other adjustable cushioning mechanisms may be incorporated
in the coupler of the present invention to act as adjustable
dampening inserts, such as the adjustable cushioning members
disclosed in U.S. patent application Ser. No. 09/160,947 entitled
"Treadmill with Adjustable Cushioning Members" to Dalebout, et al
that was filed Sep. 25, 1998, which is incorporated herein by
reference. In addition, the adjustable hub mechanisms disclosed in
a U.S. patent Application to Dalebout, et al, filed Dec. 15, 2000
entitled "Selectively Dynamic Exercise Platform," which is
incorporated herein by reference, may be employed as (or as part
of) a flexible, adjustable coupler of the exercise system disclosed
in this application.
[0076] Additional mechanisms that may be employed as (or as part
of) a movable coupler of the present invention include a universal
joint that moves in a variety of different directions and rotates
about more than one axis. Upstanding member 12 and a support base
such as base 10 can each be coupled to the universal joint.
Additional mechanisms that may be employed as (or as part of) a
movable coupler of the present invention include a ball and socket
type joint, to which member 12 and a base, such as base 10 can be
coupled.
[0077] As discussed above, the embodiment shown in FIG. 1 provides
an exercise device that simulates the action of a bicycle while
remaining stationary. Cranks 25 are one example of a exercise
mechanism that may be coupled to the upright member 12 and support
a user above a support surface. However, those skilled in the art
will appreciate that the invention may be practiced with many types
of exercise mechanisms that are coupled to the upstanding support
member 12 that is movably coupled to the support base of the
present invention. These exercise mechanisms may include a variety
of different mechanisms configured to exercise a variety of
different portions of a users body, such as the legs and/or arms of
a user. Thus, while cranks are shown in FIG. 1, a variety of
different exercise mechanisms may be coupled to the upright member
that allow a user to exercise, such as a stepper configuration,
moving stairs, a moving belt, one or more poles, bands, or cords
moved by a user's arms, and a variety of other mechanisms with
which a user can exercise. Preferably at least one of the exercise
mechanisms coupled to the upstanding member is configured to
support a user above a support surface.
[0078] The coupling of the exercise mechanism to the upright member
can be direct or indirect. For example, a cross member to which the
exercise mechanism is coupled may be coupled to the upright member,
such that the exercise mechanism is indirectly coupled to the
upright member.
[0079] The flexible couplers discussed herein, e.g., couplers 13,
48, 60, 90, 100, 110 are each examples of means for movably
coupling an upstanding support member to a base. Each of these
flexible couplers are also examples of means for flexibly coupling
an upstanding support member to a base. The flexibility of the
dampening inserts prevents sudden halting of the dampening wings, a
major advantage of the present invention.
[0080] The present invention may be embodied in other specific
forms without departing from its spirit or essential
characteristics. While a preferred embodiment of the present
invention has been described and illustrated, it will be understood
by those of ordinary skill in the art and others that certain
modifications can be made to the illustrated embodiment while
remaining within the scope of the present invention. The described
embodiments are to be considered in all respects only as
illustrative and not restrictive. The scope of the invention is,
therefore, indicated by the appended claims rather than by the
foregoing description. All changes that come within the meaning and
range of equivalency of the claims are to be embraced within their
scope.
