Description

[Technical field]

[0001] The present invention relates generally to the field of exercise, and more specifically to a "plank stand" exercise that can strengthen abdominal / back muscles, leg muscles, and other muscles while standing or sitting. [Background technology]

[0002] A wide variety of exercise equipment has been developed to specifically train the abdominal / back muscles of the user. These equipment generally require the user to change into appropriate sports clothes, go to a gym or concentrate on exercising, adjust the rather cumbersome equipment, sit on the equipment, and fasten any straps that may be necessary to use the equipment before starting the desired exercise routine. Many such equipment does not allow the user to comfortably perform other activities, such as working or meeting other people, while exercising.

[0003] A familiar exercise is also known as the "plank", in which a person rests their entire weight on their toes on one end and their elbow or forearm on the other. The aim is to hold the body in a horizontal, stationary position. Under considerable stress, a person can only maintain this position for any length of time, from a few seconds to a few minutes.

[0004] Thus, there is a need for an easy to use and safe to use plank stand that allows a user to engage in primarily static exercises for extended periods of time with low stress and effort levels, while at the same time allowing the user to participate in other activities such as typing, texting, reading, watching television, conversing, etc.

[0005] The plank exercise described above (and conventional exercise devices that can simulate the plank position) supports the exerciser's weight at both ends of the body, i.e., the legs and arms (or chest). In contrast, the plank stand supports the user at only one end of the body, i.e., under the knees (or, in a more relaxed position, under the pelvis), so that the user assumes a cantilever plank position. The advantage of this approach is that even a small angle of inclination can produce a large physical effect. Summary of the Invention

It is also to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.

[0053] The present invention provides a plank stand, an abdominal / back and leg exercise device that can also function as a workstation. The plank stand may comprise a base, a leg shaft and a leg support. Alternatively, the plank stand may comprise a base, a leg shaft, a leg support and a heel support. Alternatively, the plank stand may comprise a base, a leg shaft, a leg support and a foot support. Alternatively, the plank stand may comprise a base, a leg shaft, a leg support and a foot support. Alternatively, the plank stand may comprise a base, a leg shaft, a leg support, a heel support and a foot support. Alternatively, the plank stand may comprise a base, a leg shaft and a chair. Alternatively, the plank stand may comprise a base, a leg shaft, a leg support and another leg support that may be connected to an object, such as a table. Alternatively, the leg support and the leg shaft may be disconnected from the base and the leg support may be connected to another object, such as a table. Alternatively, the leg support may be connected to an object, such as a table. In any event, the present invention is directed to leg supports that are connected directly to the table without being disconnected from the plank stand.

[0054] 1 illustrates a front perspective view of an exemplary plank stand 100 in accordance with an embodiment of the present invention. Plank stand 100 includes a base 110, a leg shaft 120 coupled to base 110, and at least one leg support 130 (one shown) coupled to leg shaft 120.

[0055] It will be appreciated that when a user leans forward and places some of their body weight on the leg support 130, an opposing force is generated that pushes the foot backward and away from the leg support. Therefore, according to an embodiment of the present invention, the base 110 may be partially or completely covered with or include a non-slip material with a high coefficient of friction to prevent the foot from slipping backward. Examples of non-slip materials may include, but are not limited to, rubber, silicone, plastic, polyester, and the like. The non-slip material is intended to prevent the user's foot from slipping. Alternatively, according to an embodiment of the present invention, the upper side of the base 110 may have a texture or pattern.

[0056] Alternatively or additionally, resistance to this opposing force can be provided by one or two inserts into the base on which the user places their feet. Of course, a combination of non-slip materials covering the inserts provides the most resistance.

[0057] According to an embodiment of the present invention, the leg shaft 120 can be extended (e.g., by using a telescopic shaft). According to an embodiment of the present invention, the at least one leg support 130 can be cylindrical as shown, but it will be understood that the shape of the at least one leg support 130 is not limited to being cylindrical and can be any other defined or undefined shape. According to an embodiment of the present invention, the at least one leg support 130 can include one or more recesses configured to receive a user's leg. According to an embodiment of the present invention, the leg shaft 120 can be movably coupled to the base 110 via a tilting mechanism using any suitable method known in the art, such as, for example, a hinge, and can be fixed by the user at multiple angles relative to the base 110, such as, for example, 100 degrees, 95 degrees, 90 degrees, 85 degrees, 80 degrees, etc. Examples of tilting mechanisms that can be used can include, but are not limited to, a ratchet, a gas piston, and the like.

[0058] FIG. 1A illustrates the example plank stand of FIG. 1 with the leg shaft 120 extended and tilted, resulting in at least one leg support 130 in an example position.

[0059] 1B shows another exemplary embodiment of the plank stand 100 of the present invention, in which the leg shaft 120 may include two foot supports 125. The foot supports 125 are intended to allow the user to insert their feet under the foot supports so that they can lean back.

[0060] FIG. 1C illustrates the exemplary plank stand of FIG. 1B with the leg shaft 120 extended and tilted, resulting in at least one leg support 130 in an exemplary position.

[0061] FIG. 1D illustrates another exemplary embodiment of the plank stand 100 of the present invention, in which the base 110 may include two heel supports 150. When a user leans forward, the heels tend to lift off the base. Thus, the heel supports 150 engage the heels of the user while leaning forward to hold the foot. It will be appreciated that the heel supports 150 may be movably coupled to the base 110 to allow for different distances of the heel supports 150 from the leg shaft 120, thereby allowing for different lean angles of the user. It will be appreciated that the heel supports 150 may be coupled in various ways known in the art. For illustrative purposes, each heel support 150 is shown attached to two rails that allow the heel supports to be moved away from or towards the leg shaft 120 in the direction of the double arrow 155, and the heel supports to be fixed in the desired position.

[0062] FIG. 1E illustrates the exemplary plank stand of FIG. 1D with the leg shaft 120 extended and tilted, resulting in at least one leg support 130 in an exemplary position.

[0063] FIG. 1F illustrates another exemplary embodiment of the plank stand 100 of the present invention, where the plank stand 100 includes both a foot support 125 and a heel support 150.

[0064] FIG. 1G illustrates the exemplary plank stand of FIG. 1F with the leg shaft 120 extended and tilted, resulting in at least one leg support 130 in an exemplary position.

[0065] According to an embodiment of the present invention, the height of each heel support 150 can be adjusted as needed, for example, by connecting the heel support 150 to the base 110 via a hinge, by using a resilient material that allows the heel support to move, or by any method known in the art suitable for adjusting the height of the heel support 150.

[0066] 1H illustrates another exemplary embodiment of the plank stand 100 of the present invention, where the base 110 may include two inserts 170 into which a user may place their feet. It will be understood that the present invention is not limited to two inserts, and one insert for both feet may also be used.

[0067] FIG. 1I illustrates another exemplary embodiment of the plank stand 100 of the present invention, which may include at least one additional leg support 130A movably coupled to the leg shaft 120. It will be understood that the distance of the at least one additional leg support 130A from the leg shaft 120, the height of the at least one additional leg support 130A, and the angle of the at least one additional leg support 130A relative to the leg shaft 120 may be adjusted, as described below. It will also be understood that the presented embodiment may include any one of the additional features described and illustrated in connection with FIGS. 1B-1H.

[0068] Fig. 1J shows a side view of the embodiment of Fig. 1 I. According to an embodiment of the invention, at least one additional leg support 130A may be vertically adjusted in the direction of double arrow 160.

[0069] FIG. 1K shows a side view of the embodiment of FIG. 1I with a different vertical position of at least one additional leg support 130A.

[0070] 1L shows a side view of the embodiment of FIG. 1I with different angles of the at least one additional leg support 130A. According to an embodiment of the present invention, the angle of the at least one additional leg support 130A relative to the leg shaft 120 can be adjusted in the direction of double arrow 165.

[0071] 1M shows a side view of the embodiment of FIG. 1I at different horizontal positions of the at least one additional leg support 130A. According to an embodiment of the present invention, the at least one additional leg support 130A can be adjusted horizontally in the direction of the double arrow 175. Note that the horizontal position represents the distance of the additional leg support from the leg shaft 120. Thus, in the presented exemplary embodiment, the double arrow 175 is inclined.

[0072] It will be appreciated that the at least one additional leg support 130A may include and / or be coupled to the leg shaft by any suitable mechanism that allows for vertical, horizontal, and angular adjustment, such as, for example, a telescoping mechanism, a clamp, a rail, etc.

[0073] For illustrative purposes only, FIG. 2 shows an exemplary heel support 250 with two hinges 250A and 250B, one on each side of the ring 260, allowing the height of the ring 260 to be adjusted in the direction of the double arrow 255. The heel support 250 further includes an elevation mechanism (push-out element), e.g., a wedge 270 under the ring 260, intended to keep the ring elevated so that the user does not have to raise the ring into position with their heel when stepping on the base (not shown). This is just one example of how the ring of the heel support may be kept in an elevated position, and many other methods are possible. It will be understood that at least one push-out element may be used.
