DETAILED DESCRIPTION

[0034] The embodiments disclosed herein help spread the load of a user lying horizontally on an unstable surface making exercise accessible to the user and doing so safely. The exercise board can be used in all industries, but especially for physical therapy or general exercises to improve overall effectiveness of the movements being carried out to the benefit of the user. Users with limited mobility or injury may not be able to leave their bed to access exercise equipment located elsewhere. Even recovering or elderly individuals that can leave their beds and are relatively mobile may not be able to position themselves on the floor. A bed or sofa can be converted to a flat exercise surface with use of an exercise board. Exercising on top of an unstable surface like a bed without adequate support presents not only safety concerns for the user but is challenging for a physical therapist since proper positioning of the user and muscle isolation may not be possible. By having proper support, users could recover from injuries more quickly or continue to maintain their physical strength by improving the quality of their movements.

[0035] When not in use, the exercise board can be folded into a smaller size, portably relocated using the handles, a tote bag, or other suitable device, and stored for later use. In some cases, the rigid support structure of the exercise board comprises a base component constructed of high-density material that has a cushion layer formed to the upper side surface for user comfort while the user lays horizontally on the exercise board during use.

[0036] As used herein, the term “folded” means that the segments of the rigid support structure are connected with at least one pivot point, usually including a hinge, and fold towards each other to reduce the overall length of the exercise board.

[0037] Referring to the drawings, FIGS. 1-4 show a foldable exercise board generally designated as 10. The board 10 includes a first segment 12 and a second segment 14 adjacent and connected to each other at the second end portion 16 of first segment 12 and first end portion 18 of second segment 14 by a hinge 20. The hinge 20 can be a bifold locking hinge used to secure segments 12 and 14 into a functional exercise board during use and fold the board into a smaller configuration during periods of non-use. While the figures show the use of two exposed hinges 20, one or more hinges can be used depending on the configuration. In some embodiments, the hinge is recessed within recesses 21 in the second end portion 16 of first segment 12 and the first end portion 18 of second segment 14 so that the hinges 20 are not readily visible from the top side when the board is in the unfolded configuration. Additionally, while the figures show the board being made from two segments, two, three, four, or more segments could be used to form the board. FIG. 2 shows the bottom view of board 10 with two hinges 20 on the lower side surface 36 of segment 12 and a lower side surface 38 of segment 14.

[0038] A first cushion 22 is mounted to a first upper side surface 24 of the first segment 12 and a second cushion 26 is mounted to a second upper side surface 28 of the second segment 14. Cushions 22 and 26 cover the entire upper side surfaces except areas with handholds and the region proximate the hinges 20. In some embodiments, a single continuous cushion could cover upper side surfaces 24 and 28 of segments 12 and 14, respectively. When the board is in its folded configuration, the embodiment with a continuous piece of cushion covering the upper side surfaces of segments 12 and 14 will stretch over the hinged first and second end portions of segments 14 and 12, respectively. In other embodiments, the cushion is recessed within the upper side surfaces 24 and 28 of segments 12 and 14. In certain embodiments not shown, the cushion segments 22 and 26 can contact each other at the region where the second end portion 16 and first end portion 18 align when the board is in the unfolded configuration. Cushions 22 and 26 may comprise a foam material (non-limiting examples including polyurethane, polyethylene, or a combination of like materials), and in some embodiments, may be covered with a non-porous wipeable material, including but not limited to vinyl. The cushion foam may have a density in the range of 1.8-30 pounds per cubic foot. The compressibility of the foam may be tested using ASTM D3574 B1 standards, or ASTM D3574-17 standards for urethane foams. In embodiments, the pressure required to compress the cushions 25% can be in the range of about 0.3-45 psi as measured ASTM D3574 B1 standards. The cushion could also be mechanically bonded to the segments or affixed using hook and loop fasteners. The cushion could also be attached to the board using elastic or nonelastic tethers that wrap around the corners of the board, are fastened to the board or pass through already existent or newly added loops.

[0039] The version of the board 10 shown in FIGS. 1-14 has a plurality of side handholds 30 located along the length of segments 12 and 14. Each handhold 30 is similarly structured with a size and shape that would render them ergonomically comfortable for a user in the user's hand. In some embodiments, the handholds may have a triangular, rectangular or trapezoidal shape. Additionally, while the figures show the segments of the board having one handhold located along the length of each segment 12 and 14, two, three, or more handholds could be located along the length of each segment. The handholds extend partially or completely through the thickness of the board, thereby defining openings to receive hands of the user during exercise or transport of the board.

[0040] In some cases, the board 10 has a plurality of corner handholds 32 located at the corners of the non-hinged end portion of segments 12 and 14. Each corner handhold 32 is similarly structured with an ergonomic shape to render them comfortable for a user in the user's hand. The corner handholds 32 extend partially or through the thickness of the board, thereby defining openings to receive hands of the user during exercise or transport of the board.

[0041] In some embodiments, the board 10 has flexible straps 34, which can be made of nylon or another thermoplastic material 34 connected to handholds 32 at the non-hinged end portions of segments 12 and 14, thus creating additional handles for the user to transport board 10.

[0042] FIGS. 5-8 illustrate the exercise board 10 in folded configuration from several perspectives. FIG. 5 shows the exercise board 10 from the side in the preferred embodiment with the cushion on the outside when the board is in folded configuration. When the exercise board 10 is folded in the preferred embodiment, a lower side surface 36 of segment 12 and a lower side surface 38 of segment 14 come together and overlay by folding along the rotational axis of hinge 20. In FIG. 7, the straps 34 are depicted as being elevated to show cushion 22, although the straps 34 generally will be in contact with the surface upon which the folded exercise board 10 rests.

[0043] The embodiment of FIGS. 1-8 may be manufactured by injection molding a solid piece of thermoplastic material, or compression molding a thermoset material into the desired size and shape of each segment of the exercise board. A cushion would then be formed to the upper side surface of each segment. The appropriate number of segments would then be aligned and connected using at least one hinge attached to the hinged end portion of each segment. Flexible straps may then be connected to the non-hinged end portions of the segments.

[0044] Referring to FIGS. 9-11, a second embodiment of a board 110 is shown from a side view in its unfolded configuration. The board 110 encompasses a two-piece interior reinforcing structure 140 extending the entire length of first segment 112 and a two-piece interior reinforcing structure 142 extending the entire length of second segment 114 from the first end portion to the second end portion of each segment. The first segment 112 is connected to the second segment 114 by two hinges 120. The interior reinforcing structure can be formed from tubing having a rectangular cross section or a circular cross section. FIG. 10 is a cross sectional view of board 110 showing the reinforcing structure with a rectangular cross section encompassed within the rigid support structure. The reinforcing frame structure may be made of a polymer, metal, foam, or composite material, or combination thereof.

[0045] In some embodiments, including the third embodiment of the exercise board 210 shown in FIG. 12, the interior reinforcing structure extends across both the width and length of each segment of the exercise board. The broken lines show the general configuration of the interior reinforcing structure, which includes a first rectangular tubular frame 240 in first segment 212 and a second rectangular tubular structure 242 in second segment 214. The first segment 212 is connected to the second segment 214 by two hinges 220.

[0046] The embodiments of FIGS. 9-11 and 12 may be manufactured by injection molding thermoplastic material around an interior reinforcing structure fully enveloping the interior reinforcing structure, or compression molding a thermoset material around an interior reinforcing structure.

[0047] In some cases, the exercise board 310 contains a rigid foam 344, as is schematically depicted in a fourth embodiment shown in FIG. 13. The foam can be included to impart strength and/or to provide for a lighter weight board as compared to an exercise board formed from a solid thermoplastic or thermoset material. In some cases, the foam comprises polyurethane, polystyrene, and/or polyisocyanate. In embodiments, the board is injection molded or blow-molded and then filled with foam that is injected into the exercise board in liquid form and then expands to form a rigid foam core. The segments may be made of vacuum formed thermoplastic or thermoset material forming an exterior shell with a rigid foam filling the interior of each segment.

[0048] FIG. 14 illustrates use of the exercise board. The user unfolds the exercise board into its fully extended configuration, locking the hinge, and placing the board on an unstable surface orienting the cushioned side up. The user then lies horizontally on top of the board and engages in exercises. After use, the board can be put into its folded configuration and stored for later use.

[0049] FIG. 15 shows the top view of a fourth embodiment 410 that includes side holes 417 and 428. FIG. 15 also includes corner holes 434. Holes 417, 428 and 434 contain space wherein to tether elastic or nonelastic straps. The use of elastic and nonelastic resistance bands, straps or belts is well documented in the field of Physical Therapy and Wellness. If the resistance apparatus is inelastic, in some cases, the length will range from 28 inches to 160 inches with width from 0.3 inches to 18 inches. If the resistance apparatus is elastic, in some cases, the length will range from 22 inches to 160 inches with width from 6 inches to 30 inches. These can be used singly or in combination. In some embodiments, the board will have holes, hooks, ties, Velcro loops or magnetic or traditional buckles to fasten the resistance apparatus to the board. Similar to the embodiment of FIGS. 1-8, this embodiment includes a first segment 412 and a second segment 414 connected by hinges disposed in recesses 421 that connect the two segments to one another. A first cushion 422 is mounted to the upper side surface 424 of a first segment 412 and a second cushion 426 is mounted to a second upper side surface 427 of the second segment 414. This embodiment includes side handholds 430.

[0050] FIG. 16 shows the top view of a fifth embodiment 510 that includes protruding side hooks or loops 518 and 523 and protruding side hooks or loops 520 and 534 wherein to attach elastic or nonelastic straps. In some cases, the straps have the same dimensions as in FIG. 15. Similar to the embodiment of FIGS. 1-8, this embodiment includes a first segment 512 and a second segment 514 connected by hinges disposed in recesses 521 that connect the two segments to one another. A first cushion 522 is mounted to the upper side surface 524 of a first segment 512 and a second cushion 526 is mounted to a second upper side surface 528 of the second segment 514.
