DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[0028] One aspect of the present invention involves an exercise
device that includes a platform portion, a frame portion, and a
resistance device. The frame is pivotally attached to the platform
through a pivot locking device that allows the frame to be fixed in
a plurality of orientations relative to the platform. One or more
resistance devices may be secured to various locations on the
platform or various locations on the frame. In one particular
embodiment, the resistance device includes an elastic band with a
handle coupled with the band. By attaching the band and handle to
one of the many locations on the platform or frame, the user may
perform numerous different exercises.
[0029] The height and width of the frame can be adjusted to conform
to the physical characteristics of a user and to perform various
exercises. The exercise device is configured to allow the user to
stand or sit in various positions on the platform portion while
performing various exercises. Once in position, the user grasps a
handle and pulls to extend the elastic band. Additionally, the
platform and frame is compact in its use configuration, and also
may be folded into a compact storage configuration.
[0030] FIGS. 1-2 show one particular exercise device 10 conforming
to the present invention. The exercise device is set on a support
surface, such as a floor. The exercise device includes a platform
12 with an upper surface 14 and a lower surface 16. As shown in
FIG. 2, a user stands or sits on the upper surface of the platform
portion. In FIG. 2, the user is shown performing a bicep curl with
each arm, by pulling upward on a resistance device 18 coupled with
the frame at two locations. By standing or sitting on the platform,
the user's weight helps to steady the exercise device from the
force imparted by the user during exercise.
[0031] Various platform shapes may be utilized. In the particular
example of FIGS. 1 and 2, the platform 12 defines a generally
rectangular or square area with rounded extensions (20A, 20B, 20C,
20D) protruding outwardly from each of four corner regions.
Additionally, the platform includes a front edge 22A, a back edge
22C, a right edge 22B, and a left edge 22D. The rounded extensions
provide additional stability to the platform portion as well as
additional area where a user can sit or stand.
[0032] A frame 24 is pivotally supported at the center of the front
edge 22A of the platform. The front edge extends between the two
forward rounded extensions (20A, 20D). Additionally, the front edge
is generally concave between the rounded extensions. The rounded
extensions 26 extend both forwardly and outwardly of the front
edge. Similarly, the rear edge of the platform portion extends
between the two rearward and outward extending rounded extensions
(20B, 20C) and is generally concave between the rear rounded
extensions. The right and left edges (22B, 22D) of the platform
portion extend between the respective rearward extensions and
forward extensions. Between the rearward and forward extensions,
the right edge curves slightly inward toward the center of the
platform adjacent the extensions, and defines a convex section
(26B, 26D) between the inward curves. A first gripping area 26 is
defined in the platform adjacent the convex section. The left edge
22D is a mirror image of the right edge. Further, a second gripping
28 area is defined just inward the convex portion 26D of the left
edge. In one implementation, each gripping area defines half-moon
shape with a generally straight edge intersecting an arcuate edge.
The gripping areas provide a place for a user to grasp the platform
portion in order to carry, reposition, or stock the exercise
device.
[0033] Still referring to FIGS. 1-2, the frame 24 is pivotally
connected with the platform portion. The frame, in one example, is
an assembly including a lower support member 30 pivotally coupled
with the platform. An upper support member 32 is movably coupled
with the lower support member. A cross-member 34 is attached to the
upper support member. A left extending member 36 and a right
extending member 38 are movably supported in the cross-member
Generally, the frame members are constructed of rectangular hollow
steel tubing, but the cross section can be any shape. Additionally,
other frame member constructions may be used.
[0034] The lower support member 30 is connected with the platform
12 through a pivot locking mechanism 36, discussed in more detail
below. The lower support member and upper support member 32 are
telescopically connected such that the outer perimeter of the upper
support member is sized so that the upper support member can slide
in and out of the lower support member 30. FIG. 3 shows the upper
support member extended upwardly from the lower support member.
Telescoping the upper support member (and cross-member) provides
numerous potential exercises, depending on how high the upper
support member is telescoped. In other embodiments, the outer
perimeter of the lower support member may be sized so that the
lower support member can slide over the upper support member. A
locking mechanism 38 is positioned on the lower support member to
engage one of a plurality of support member holes 40 in the upper
support member to secure the upper support with respect to the
lower member. The upper support member holes are located in a side
of the upper support member. The locking mechanism is secured to
the upper support on the same side as the holes.
[0035] Various types of locking mechanisms may be utilized in
exercise devices conforming to the present invention. FIG. 4A is a
close-up isometric view of the locking mechanism 38 and adjacent
frame members. FIG. 4B is a section view through the locking
mechanism. In the particular examples discussed herein, the locking
mechanism 38 includes a spring loaded pop-pin 42. The pop-pin
includes a hollow cylindrical base portion 44, a cap 46, a spring
48, a locking pin 50, and a knob 52. The hollow cylindrical base
portion is integrally connected with the lower support member. The
cap is threadedly connected with the cylindrical base portion. A
first end of the locking pin fits inside the cylindrical base
member and includes a spring platform 54. The knob 52 is threadably
connected with a second end of the locking pin that protrudes from
the cylindrical base portion though the cap. The spring 48 is
compressed between the spring platform and the cap such that the
locking pin is forced toward the inside of the lower support member
by the force of the spring. The locking pin is sized to engage any
one of the plurality of upper support member holes 40.
[0036] When adjusting the height of the upper support member, the
user first pulls on the knob 52 to disengage the locking pin 50
from one of the plurality of upper support member holes 40. The
user then slides the upper support member 32 in or out of the lower
support member 30 to the desired height. The user then releases the
knob and the spring 48 forces the locking pin against the upper
support member or into an upper support hole. If the pin abuts the
member, the user moves the upper support member slightly up or down
until the locking pin pops into one of the plurality of upper
support member holes. The pop-pin 42 may then be locked so it
cannot be easily disengaged. In one example, the pin adjacent the
handle is threaded, and it may be turned into the cylinder, which
defines a corresponding threaded base. Various locking mechanisms
known in the art can be utilized to aid in adjusting the position
of the upper support member and the present invention should not be
construed to be limited to the type of locking mechanism described
above.
[0037] As shown in FIGS. 1-4A, the upper support member 32 is
integrally connected with a middle portion of the cross-member 34,
forming generally a T-shape between the upper support member and
the cross-member. The left extending member 35 and the right
extending member 37 are telescopically connected with the
cross-member in that the extending members are sized such that they
can slide in and out of the cross-member. FIG. 4A shows the right
extending member extended outwardly from the cross-member. The
right and left extending members have a plurality of extending
member holes 56 located along a top surface of the extending
member. Locking mechanisms 38 are positioned on the cross-member to
engage the extending member holes and fix the positions of the left
extending member and the right extending member relative to the
cross-member at a plurality of locations.
[0038] The pop-pin 42 of FIG. 4B or other suitable device may be
employed as the extension member locking mechanisms. When adjusting
the horizontal position of the right extending member, the user
first pulls on the knob 52 to disengage the pin from one of the
plurality of extending member holes. The user then slides the right
extending member 37 in or out of the cross-member 34 to the desired
location. The user then releases the knob and the spring forces the
locking pin against the right extending member. Next, the user
moves the right extending member slightly right or left until the
locking pin engages one of the plurality of extending member holes.
The position of the left extending member is adjusted in the same
manner as previously described with respect to the right extending
member.
[0039] As shown in FIGS. 1, 2, and others, each extending member
has a clip hook 58. The clip hooks are located at the outward ends
of each extending member. Additionally, the clip hooks project
rearwardly toward the user. FIG. 5 is a close-up side view of the
clip hook. The clip hooks are used to secure a resistance device to
the frame, as discussed in more detail below. The clip hook defines
a hook portion 60, a sliding member 62, a middle portion 64, and a
threaded portion 66. The threaded portion extends from the middle
portion to an end. The hook portion extends from the middle portion
in a curved path defining a hook shape. The sliding member slides
in and out of the middle portion. Typically, the sliding member is
biased by a clip hook spring (not shown) so that the sliding member
is forced against the hook portion, which creates a normally closed
perimeter of the clip hook. The clip hook is connected with the
left and right extending members by first screwing a locking nut 68
on the threaded portion and then passing the threaded portion
through a clip hook hole on a rearward side of the extending
members. A clip hook screw cap 20 is then screwed onto the threaded
portion. The locking nut is tightened until the screw cap is held
flush against the extending member to securely hold the clip hook
in place. Other attaching mechanisms, such as carabiners, snap
hooks, eyelets, etc., may also be employed in embodiments of the
invention. Moreover, the attaching mechanisms may be secured to
other portions of the extending members, the frame, and the
platform.
[0040] As discussed above, the lower support member 30 is connected
with the platform portion through the pivot locking mechanism 36
that allows the frame portion to pivot relative to the platform
portion. FIG. 1 shows the frame in a vertical orientation. FIG. 6
shows the frame pivoted downward into a horizontal position. The
position of FIG. 6 facilitates various exercises as well as
storage. FIG. 7 is a close-up right side view of the pivot locking
mechanism as shown in FIG. 1 and others. FIG. 8 is a close-up right
side view of the pivot assembly with the frame in the horizontal
position as shown in FIG. 6. FIG. 9 is a close-up right side view
of the pivot locking mechanism in an intermediate position. FIG. 10
is a section view taken along line 10-10 of FIG. 7. Referring to
FIGS. 6-9 and others, the pivot locking mechanism 38 includes a
base plate 74, a first semicircular plate 76, and a second
semicircular plate 78. The base plate is affixed to the platform
portion by any suitable means, such as bolting, adhesive, or
welding. The first semicircular plate and second semicircular plate
each have a pivot axle hole 80 located therein and are integrally
connected with the base plate. A plurality of pivot locking holes
82 are also located generally in an arc along the outer
circumference of the second semicircular plate.
[0041] The lower support is pivotally mounted between the plates at
a pivot axle 84. An arched end cap 86 is affixed to a lower end of
the lower support member. Axle holes (not shown) are located in
both the right and left sides of the arched end cap. The
corresponding axle holes 80 are also defined in the plates. The
pivot axle passes through the axle holes. The frame portion 24 can
rotate in a forward and rearward direction about the pivot
axle.
[0042] The pivot locking mechanism includes a pop-pin type 42
locking mechanism 36 secured to the lower member on the side
opposite the second semicircular plate. The pop-pin is adapted to
engage one of the holes 82 in the second plate 78 and thereby
secure the frame in one of the pivot positions. The pivot locking
mechanism is similar to the other locking mechanisms discussed
herein. When adjusting the rotational or pivotal position of the
frame portion, the user first pulls on the knob to disengage the
locking pin from one of the plurality of pivot locking holes. The
pin is of sufficient length to extend through both plates (76, 78)
and the support member 30. Additionally, the pin arrangement
provides space for the pin to move at least a sufficient distance
to disengage from one plate and the support so the support may
pivot. The user then pivots the frame member about the pivot axle
84 to the desired location. The user then releases the knob and the
spring forces the locking pin against the second semicircular plate
or into a pivot locking hole. If the pin does not engage a hole,
the user moves the frame member slightly back and forth until the
pin pops into one of the pivot locking holes.
[0043] As shown in FIG. 6, the pivot locking device 36 allows the
user to pivot the frame 14 downward and rearward until the frame
members (30, 32, 34) are adjacent the platform 12. Configuring the
exercise device in the fully closed position allows the user to
more easily transport, carry, and store the exercise device when
not in use.
[0044] As shown in FIG. 11, the pivot locking device 36 also allows
the user to pivot the frame 24 fully forward and downward until the
lower support member 30 extends outwardly from the platform 12
parallel to the floor. The plurality of pivot locking holes on the
pivot locking mechanism also allows a user to pivot and lock the
position of the frame portion in various positions between the
fully closed position and the fully open position (see, for
example, FIG. 9). The locking mechanism can also be slotted to
allow for infinite positional adjustments. The exercise performed
with the exercise device 10 configured in the orientation of FIG.
11 is discussed further below.
[0045] As shown in FIG. 12, the resistance device 18 includes a
handle 88 coupled with an elastic band 90. The elastic band may be
secured to one of the various clip hooks 58. The handle portion
includes a rigid gripping handle 92 supported on a strap 94. A
handle hook 96 is connected with the strap. The handle hook
includes a ring portion 98 and a clip hook portion 100. The ring
portion defines a rectangular slot with two long sides and two
short sides. The ring portion movably supports the strap. The clip
hook portion includes a pivoting base 102 integrally connected with
a snap hook 104 that has an arm biased in a closed position to
provide the clip hook portion with a normally closed perimeter. The
pivoting base of the clip hook portion is pivotally connected with
one of the long sides of the ring portion. The clip hook may be
clipped to a corresponding closed ring 106 secured to the elastic
band 90. The rigid gripping handle 88 is defined by a hollow
cylinder and is typically constructed of a relatively strong
material such as plastic, steel, or aluminum. The strap 94 is a
closed loop that passes through the center of the rigid gripping
handle and through the rectangular aperture of the ring portion of
the handle hook.
[0046] Still referring to FIG. 12, a loop 108 is connected with a
second end of the elastic band. The ring is used to couple the
resistance device to a clip hook 58. Other fastening means, such as
a swivel hook including a ring portion and a snap hook rotatably
connected with the ring portion may also be connected to the band.
Allowing the snap hook to turn 360 degrees relative to the ring
portion helps to eliminate any twisting of the elastic band that
might occur during exercise. The swivel hook releasably connects
with the clip hook mounted on both of the right and left extending
members.
[0047] It should be noted that the elastic band 90 may be
fabricated from any resilient material capable of returning to its
original shape after being stretched. For example, the elastic band
can be constructed from thermal plastic rubber, latex, Kraton.RTM.
rubber, and elastic fabric. It is also possible to substitute an
elongate spring of suitable spring constant for the elastic band.
Additionally, it is possible to utilize more than one elastic band
in a resistance device to increase exercise resistance.
[0048] The present invention is easily configured to accommodate
the user's physical size for performing various different
exercises. For example, as shown in FIG. 2, the exercise device is
configured to allow the user to perform a bicep curling exercise
with his or her right and left arms. The frame 24 is rotated and
locked in an upright position, as described above, such that the
lower support member 30 is at a right angle with reference to the
platform 12. The resistance devices 18 are connected with the clip
hooks 58 located on the left and right extending members (35, 37).
The extending members are positioned perpendicularly relative to
the upper support member such that the clip hooks are located in
front of the user's left and right arms, respectively, when the
user is facing forward while standing on the platform portion. The
user then grasps the handles 88 with his or her hands and bends his
or her arm at the elbow while keeping his or her upper arm
generally perpendicular to the upper surface of the platform
portion. The resistance force increases as the elastic band is
stretched. In the arrangement of FIG. 2, the user may perform curls
with one or both arms.
[0049] Additionally, in any exercise, it is possible to couple a
first resistance device at a first connecting point (e.g., left
extending member clip hook) and a second resistance device at a
second connecting point (e.g., right extending member clip hook).
Each resistance device may be connected to a bar, and the user may
perform various exercises by grasping the bar and extending both
bands.
[0050] The height of the upper support member 32 and cross bar 34
can be adjusted to accommodate various types of exercises, such as
the military press. Adjusting the height of the upper support
member and cross-member can also affect the force required to
perform a particular exercise for a given resistance system. For
example, increasing the height of the upper support member and
cross-member for the arm curling exercise performed in FIG. 1 would
result in the user exerting less force to perform the arm curling
exercise with the same resistance device.
[0051] Adjusting the pivotal location of the frame 24 relative to
the platform 12 can also have an affect on the force required to
perform a particular exercise for a given resistance system. For
example, as shown in FIG. 13, rotating the frame portion forward
from the position shown in FIG. 2 would require the user to stretch
the resistance system a greater distance, which would in turn
require the user to exert more force while performing the bicep
curling exercise. Also, adjusting the pivotal location of the frame
portion can affect how muscles are worked for the same exercise
because the user is required to stretch the resistance device
differently.
[0052] As shown in FIG. 11, the exercise device may be configured
to perform a rowing type exercise. The frame 24 is rotated forward
until the cross-member is parallel the floor. One resistance device
18 is connected with the clip hook 58 on the right extending member
37 and a second resistance device 18 is connected with the clip
hook 58 on the left extending member 35. The extending members'
horizontal positions are adjusted right or left to place the clip
hook in the desired location in front of the user. By increasing or
decreasing the separation between the clip hooks, the various arm
and back muscles may be exercised differently. The user sits on the
platform 12 and pulls against the resistance devices. The user can
also brace his feet against the cross-member to keep from sliding
across the platform portion while pulling against the resistance
system.
[0053] Other configurations of the resistance system can be
utilized to accommodate other types of exercises. For example, as
mentioned above, the handle portion can be replaced with a single
bar that allows the user to grasp the bar with both hands. It is
possible to use an exercise foot harness, such as the foot harness
described in U.S. patent application Ser. No. 10/911,141, filed
Aug. 3, 2004, and titled "Exercise Foot Harness," which is hereby
incorporated by reference herein. In another configuration, the
handle portion can be replaced with a belt that fits around the
user's waist to allow the user to perform exercises that focus more
on the back and leg muscles. In yet another configuration, the
handle portion is replaced by a small loop that fits around the
user's ankle to allow the user to perform exercises that focus more
on the leg and hip muscles. Clip hooks can also be located in
additional locations on the exercise device to allow for various
other types of exercises. For example, clip hooks can be located on
the cross bar, the upper support member, lower support member, and
the platform member.
[0054] In addition, the exercise device 10 can be used with other
accessories known in the art, such as balance balls and balance
plates. For example, as shown in FIGS. 14A and 14B, a user can
perform exercises on the exercise device in combination with a
balance ball. The balance ball is placed on the platform 12 and the
frame 24 is tilted forward. The user sits on the balance ball and
places his or her feet on the forward rounded extensions (20A,
20D). As shown in FIGS. 14A and 14B, the user is performing a
rowing exercise while sitting on the balance ball. In another
configuration (not shown), the user places the balance ball on the
floor and his or her feet on the platform of the exercise device
while performing exercises. Using the balance ball requires to the
user to utilize additional muscles in order to maintain position on
the platform portion while performing a given exercise. Similarly,
as shown in FIG. 15, a user can perform exercises on the exercise
device in combination with a balance plate 112. The balance plate
is placed on the platform 12 and the frame 24 is tilted forward. As
shown in FIG. 15, the user is performing an arm curling exercise
while standing on the balance plate. The balance plate also
requires the user to work additional muscles in order to maintain
balance on the platform portion while performing a given exercise.
The exercise device of FIGS. 14A, 14B, and 15 employs an
alternative cross bar discussed below with regard to FIG. 17.
[0055] Other embodiments of the present invention utilize platforms
and frames with alternate designs to provide better traction for
the user as well as allowing for easy storage of the exercise
device.
[0056] A first alternative embodiment of an exercise device 10
conforming to the present invention is shown in FIG. 16. The
platform 12 of the exercise device includes a plurality of ridges
114 in various shapes and in various locations on the upper surface
14 to provide better traction for the user. Base supports 116 are
located below the rounded extensions (20A-20D), which elevate the
lower surface 16 of the platform 12 from the floor. Because the
lower surface is elevated above the floor, grasping the gripping
areas (26, 28) is made easier when lifting the exercise device.
Elevated disk portions 118 are located on the tops of the rounded
extensions, and corresponding disk indentations (not shown) are
located under the base supports. As shown in FIG. 17, when stacking
one exercise device on another for storage or during shipping, the
elevated disk portions of the bottom exercise device fit into
corresponding disk indentations on the top exercise device, which
prevents the top exercise device from sliding off the bottom
exercise device. Instead of using clip hooks to attach the
resistance device to the frame portion, hoop connectors 120 are
welded to various locations in the frame portion.
[0057] A second alternative embodiment of a first exercise device
10A conforming to the present invention stacked on top of a second
exercise device 10B is shown in FIG. 17. The plurality of ridges on
the platform portion shown in FIG. 17 are slightly different from
those depicted in FIG. 16, but the base supports 116 and rounded
extensions (20A-20D) are the same as those depicted in FIG. 16. The
cross-member 34 depicted in FIG. 17 is defined by an arcuate middle
portion 122 between a straight left end portion 124 and a straight
right end portion 126. The arcuate middle portion is connected with
the upper support member 32. Hoop connectors 120 are located on an
outer region of the straight right end portion, and on the outer
region of the straight left end portion. Additional hoop connectors
are located on the cross-member near where the straight left end
portion and the straight right end portion connect with the arcuate
middle portion. Hoop connectors 120 are also located on the upper
support member and lower support member.
[0058] As shown in FIG. 17, when the frame 24 is in the fully
closed position, the cross bar 34 extends beyond the right edge 22B
and left edge 22D of the platform portion. In order to prevent
interference between the platform 12 of the first stacked exercise
device 10A and the cross bar 34 of the second exercise device 10B
when stacked, a frame notch 128 is located in the bottom surface of
the platform portion. As shown in FIG. 17, the exercise device
according the present invention can be configured for efficient
shipping and storage in any number of locations. For example,
exercise devices can be stacked and temporarily stored in a closet,
under a bed, or in a remote area of a gym to conserve precious
floor space.
