DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 <BR> <BR> 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.

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.

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.

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.

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.

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.

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.

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.

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, Kraton0 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.

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.

Additionally, in any exercise, it is possible to couple a first resistance device at a first <BR> <BR> 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.

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.

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.

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.

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 no.

10/911, 141, filed August 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.

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.

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.

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.

A second alternative embodiment of a first exercise device 10A conforming to the present invention stacked on top of a second exercise device 1 OB 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.

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.
