Description

Technical Field

[0001] The present invention relates to an exercise assist device.

Background Art

[0002] Conventionally, exercises have been performed to maintain and improve physical ability. As such an exercise, there is bodyweight training that uses only the gravity acting on the body. Since bodyweight training uses only the gravity acting on one's own body, it does not require any special training equipment and can be performed without being restricted by location or time.

[0003] In addition, in order to further enhance the effect of bodyweight training, devices such as those described in Non-Patent Document 1 have also been developed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the push-up bar described in Non-Patent Document 1 mentioned above has room for improvement from the viewpoint of further enhancing the effect of training.

[0006] Specifically, in Non-Patent Document 1, although aesthetics and lightness can be ensured to a certain extent, there is still room for improvement from the perspective of stability. If the stability of the push-up bar is insufficient, when the user exercises using the push-up bar, the posture of the user during exercise becomes unstable, and not only is it impossible to obtain a sufficient exercise effect, but there is also a risk of causing injury.

[0007] The present invention has been made in view of such problems, and an object of the present invention is to provide an exercise assist device with further improved stability during use.

Means for Solving the Problems

[0008] An exercise assist device according to an embodiment of the present invention is an exercise assist device that is placed on the ground surface and grasped by the user when the user performs exercise, and includes a grip portion, a first grounding portion, and a second grounding portion. When the longitudinal direction of the grip portion is defined as the first direction, the direction orthogonal to the first direction and parallel to the ground surface is defined as the second direction, and the direction orthogonal to the first direction and the second direction is defined as the third direction, the lengths of the first grounding portion and the second grounding portion along the first direction are longer than the grip portion.

Effects of the Invention

[0009] According to the exercise assist device of the present invention, since the first grounding portion and the second grounding portion are longer than the grip portion along the first direction, when performing exercise, the user can stably grasp the grip portion.

Embodiments for Carrying Out the Invention

[0011] Hereinafter, an exercise assist device 10 according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0012] The correspondence between the directions described in the claims and the directions described in the embodiments will be explained. The first direction described in the claims is the front-rear direction described in the embodiments. The second direction described in the claims is the left-right direction described in the embodiments. The up-down direction described in the claims is the up-down direction described in the embodiments.

[0013] FIG. 1A is a top view showing the exercise assist device 10. FIG. 1B is a side view showing the gripping part 11 and the second grounding part 13 of the exercise assist device 10 according to the present embodiment. FIG. 1C is a side view showing the gripping part 11 and the first grounding part 12 of the exercise assist device 10 according to the present embodiment. Here, FIGS. 1B and 1C are side views of the exercise assist device 10 seen from the right side. Also, in FIG. 1B, only the gripping part 11 and the second grounding part 13 are shown, and in FIG. 1C, only the gripping part 11 and the first grounding part 12 are shown. Here, the exercise assist device 10 may also be referred to as a push bar, a push-up bar, etc.

[0014] The exercise aid 10 is an instrument that is placed on the ground surface 15 and grasped by the user when the user performs exercises. Here, an example of the exercise is push-ups or handstands. The exercise aid 10 mainly includes a gripping part 11, a first grounding part 12, and a second grounding part 13. Further, the exercise aid 10 further includes a first straight part 21, a second straight part 22, a third straight part 23, a first curved part 24, and a second curved part 25. Also, the first straight part 21, the second straight part 22, the third straight part 23, the first curved part 24, and the second curved part 25 are composed of a curved rod-shaped member 20. The rod-shaped member 20 is, for example, a metal rod having a tubular shape.

[0015] The gripping part 11 is the first straight part 21 and extends linearly along the front-rear direction. The gripping part 11 is the part that the user grasps during exercise.

[0016] The first grounding part 12 is the second straight part 22, extends linearly along the front-rear direction, is disposed below the first straight part 21, and is disposed on the left side, which is one side along the left-right direction. The first grounding part 12 is the part that contacts the ground surface 15 during exercise.

[0017] The second grounding part 13 is the third straight part 23, extends linearly along the front-rear direction, is disposed below the first straight part 21, and is disposed on the right side, which is the other side along the left-right direction. The second grounding part 13 is the part that contacts the ground surface 15 during exercise.

[0018] The first curved part 24 curves so as to connect the first straight part 21 and the second straight part 22.

[0019] The second curved part 25 curves so as to connect the first straight part 21 and the third straight part 23.

[0020] In the exercise aid 10, the lengths of the first grounding part 12 and the second grounding part 13 along the front-rear direction are longer than that of the gripping part 11. By doing so, since the first grounding part 12 and the second grounding part 13 are made longer than the gripping part 11 along the front-rear direction, when performing the exercise, the user can stably grasp the gripping part 11.

[0021] In the front - rear direction, both ends of the first grounding portion 12 and the second grounding portion 13 are arranged outside the gripping portion 11. Specifically, the front end portion of the first grounding portion 12 is arranged on the front side of the front end portion of the gripping portion 11, and the rear end portion of the first grounding portion 12 is arranged on the rear side of the rear end portion of the gripping portion 11. Also, the front end portion of the second grounding portion 13 is arranged on the front side of the front end portion of the gripping portion 11, and the rear end portion of the second grounding portion 13 is arranged on the rear side of the rear end portion of the gripping portion 11. Further, when the length of the gripping portion 11 is L11, the length of the first grounding portion 12 is L12, and the length of the second grounding portion 13 is L13, L12 and L13 are substantially equal. Also, L12 and L13 are longer than L11.

[0022] Here, the function of the exercise assist device 10 when performing a push - up, which is an example of an exercise using the exercise assist device 10 shown in FIG. 1A etc., will be described.

[0023] First, as shown in FIGS. 1B and 1C, the exercise assist device 10 is placed on the ground surface 15. On the ground surface 15, the lower sides of the first grounding portion 12 and the second grounding portion 13 of the exercise assist device 10 come into contact. The first grounding portion 12 and the second grounding portion 13 have a substantially circular cross - sectional shape. Thus, even when the first grounding portion 12 and the second grounding portion 13 contact the ground surface 15, the ground surface 15 is prevented from being damaged thereby.

[0024] Next, the user performs a predetermined exercise while gripping the gripping portion 11 of the exercise assist device 10. Examples of the exercise include push - ups and handstands. Here, when the user exercises using both hands, two exercise assist devices 10 are used corresponding to the left and right hands. By performing a push - up using the exercise assist device 10, the user can sink their chest downward, so that the exercise effect obtained from the push - up can be made remarkable.

[0025] Here, in the motion assist device 10 of the present embodiment, in the front-rear direction, since the first grounding portion 12 and the second grounding portion 13 are longer than the gripping portion 11, the motion assist device 10 firmly supports the user's hand. Therefore, the user can perform exercises stably and effectively.

[0026] FIG. 2A is a top view showing a motion assist device 10 according to another embodiment. FIG. 2B is a side view showing the gripping portion 11 and the second grounding portion 13 of the motion assist device 10 according to another embodiment. FIG. 2C is a side view showing the gripping portion 11 and the first grounding portion 12 of the motion assist device 10 according to another embodiment.

[0027] The configuration of the motion assist device 10 shown in FIGS. 2A to 2C is basically the same as that shown in FIGS. 1A to 1C, except that it has a cylindrical member 31 for the gripping portion to a cylindrical member 33 for the second grounding portion.

[0028] In the motion assist device 10, the gripping portion 11 is a cylindrical member 31 for the gripping portion into which the first straight portion 21 is inserted. The first grounding portion 12 is a cylindrical member 32 for the first grounding portion into which the second straight portion 22 is inserted. The second grounding portion 13 is a cylindrical member 33 for the second grounding portion into which the third straight portion 23 is inserted.

[0029] The cylindrical member 31 for the gripping portion, the cylindrical member 32 for the first grounding portion, and the cylindrical member 33 for the second grounding portion are made of a material softer than the rod-shaped member 20, such as a foamed resin or the like. Since the cylindrical member 31 for the gripping portion is made of a soft material, when the user grips the cylindrical member 31 for the gripping portion, the user's hand can be protected. Since the cylindrical member 32 for the first grounding portion and the cylindrical member 33 for the second grounding portion are made of a soft material, the cylindrical member 32 for the first grounding portion and the cylindrical member 33 for the second grounding portion come into contact with the ground surface 15 during use. Therefore, it is possible to prevent the motion assist device 10 from damaging the ground surface 15.

[0030] Also, in the front-rear direction, since both ends of the first grounding portion 12 and the second grounding portion 13 are arranged outside the gripping portion 11, the first grounding portion 12 and the second grounding portion 13 can stably support the gripping portion 11.

[0031] Referring to FIG. 2A, in the front-rear direction, both ends of the first cylindrical member 32 for the grounding portion and the second cylindrical member 33 for the grounding portion are disposed outside the cylindrical member 31 for the gripping portion. Specifically, in the front-rear direction, let the length of the cylindrical member 31 for the gripping portion be L21, the length of the first cylindrical member 32 for the grounding portion be L22, and the length of the second cylindrical member 33 for the grounding portion be L23. In this case, L22 and L23 are substantially the same. Also, L22 and L23 are longer than L21. Further, the front end portions of the first cylindrical member 32 for the grounding portion and the second cylindrical member 33 for the grounding portion are disposed forward of the front end portion of the cylindrical member 31 for the gripping portion. Also, the rear end portions of the first cylindrical member 32 for the grounding portion and the second cylindrical member 33 for the grounding portion are disposed rearward of the rear end portion of the cylindrical member 31 for the gripping portion. By doing so, in the front-rear direction, both ends of the second cylindrical member and the third cylindrical member are disposed outside the gripping portion 11, so that the gripping portion 11 can be stably supported by the first grounding portion 12 and the second grounding portion 13.

[0032] Here, the function of the exercise assist device 10 when performing a push-up, which is an example of an exercise using the exercise assist device 10 shown in FIG. 2A and the like, will be described.

[0033] First, as shown in FIGS. 2B and 2C, the exercise assist device 10 is placed on the ground surface 15. On the ground surface 15, the lower sides of the first cylindrical member 32 for the grounding portion and the second cylindrical member 33 for the grounding portion of the exercise assist device 10 come into contact. The first cylindrical member 32 for the grounding portion and the second cylindrical member 33 for the grounding portion are made of a flexible material having a substantially circular cross-sectional shape. Therefore, even when the first cylindrical member 32 for the grounding portion and the second cylindrical member 33 for the grounding portion contact the ground surface 15, the ground surface 15 is prevented from being damaged thereby.

[0034] Next, the user performs a predetermined exercise while gripping the cylindrical member 31 for the gripping portion. Examples of the exercise include push-ups and handstands. Here, when the user exercises using both hands, two exercise assist devices 10 are used corresponding to the left and right hands.

[0035] In the motion assist device 10 of the present embodiment, in the front-rear direction, since the first ground contact portion cylindrical member 32 and the second ground contact portion cylindrical member 33 are longer than the grip portion cylindrical member 31, the motion assist device 10 firmly supports the user's hand. Therefore, the user can perform the motion stably and effectively.
