The reinforcing plate 32 reinforces the rotating plate 30 together with the reinforcing plate 31 and improves the rigidity of the rotating plate 30. The dimensions of the reinforcing plates 31 and 32 can be set arbitrarily. Further, whether or not the reinforcing plates 31 and 32 are provided is arbitrary, and the reinforcing plates 31 and 32 may not be provided. The rotating plate 30 is fixed to a rotating table 35 described later, and can be rotated by the rotating table 35.

  FIG. 6 is an exploded perspective view showing an example of the turntable 35. The turntable 35 is disposed below the turntable 30 and is provided in a state of being embedded in the base 10. As shown in FIG. 6, the turntable 35 includes a base 35a, a rotating member 35b, a rotating roller 35c, a bearing 35d, a shaft portion 35e, and a rotating spacer 35f. The base 35 a is fixed in a state of being embedded on the support surface 10 a side of the base 10. The rotating member 35b is placed on the base 35a via the four rotating rollers 35c, and is provided to be rotatable with respect to the base 35a.

  The rotating roller 35c is disposed between the base 35a and the rotating member 35b. The four rotation rollers 35c are arranged in a plurality at equal intervals in the direction around the central axis AX. The rotating roller 35c is supported by a bearing 35d so as to be able to roll in a tangential direction of a circle centered on the central axis AX. The rotating roller 35c can roll while supporting the rotating member 35b. The bearing 35d is provided on the base 35a. As the rotating roller 35c rolls, the rotating member 35b rotates around the center axis AX with respect to the base 35a.

  In this embodiment, a case where four rotation rollers 35c and four bearings 35d are arranged in the direction around the central axis AX is described as an example. However, the present invention is not limited to this, and three rotation rollers 35c and three bearings 35d are provided. It may be 5 or more. The rotation spacer 35f is disposed between the shaft portion 35e and the rotation member 35b, and supports the rotation center portion (near the center axis AX) of the rotation member 35b.

  The lock mechanism 40 can lock the rotation of the rotating plate 30. The lock mechanism 40 includes a brake mechanism (not shown) that restricts rotation of at least one of the rotation member 35b, the rotation roller 35c, and the rotation plate 30. The lock mechanism 40 locks the rotation of the rotating plate 30 by restricting at least one rotation of the rotating member 35b, the rotating roller 35c, and the rotating plate 30 by the brake mechanism.

  The lock mechanism 40 includes a lever 41 in the vicinity of the grip portion 22 that switches between a state in which the rotation of the rotary plate 30 is locked and a state in which the lock of the rotary plate 30 is released. FIG. 7 is an enlarged perspective view showing the periphery of the lever 41 of the lock mechanism 40. As shown in FIG. 7, the lever 41 is provided at the upper end of the support column 21 in the vicinity of the grip portion 22. For example, the lock mechanism 40 may be configured to lock the rotation of the rotating plate 30 by a link mechanism or the like coupled to the lever 41, or to the base 10 by an electrical switch to which the lever 41 is connected. The structure which drives the electric motor etc. with which it is equipped and locks rotation of the rotating plate 30 may be sufficient. These link mechanisms or electrical wiring may be arranged, for example, inside the column 21.

  The lever 41 is disposed at a position where the user can operate while sitting on the wheelchair C. For example, the lever 41 can be unlocked by rotating the lever 41 about the vertical direction as an axis. The lock mechanism 40 may release the lock of the rotating plate 30 by removing a fixing pin (not shown) after rotating the lever 41. This fixing pin is connected to a wire, for example, and may be configured to remove the fixing pin by pulling up the wire.

  Further, as shown in FIG. 7, a switch 42 is provided around the lever 41. The switch 42 has a ratchet claw. For example, when the switch 42 is tilted to the right, the ratchet is released, and the lever 41 can be rotated in the reverse direction (the direction opposite to the unlocking direction). By turning the lever 41 in the reverse direction, the fixing pin (not shown) returns to the original position, and the rotation of the rotating plate 30 can be locked. The arrangement of the lever 41 is arbitrary, and may be provided in a part of the handrail 20 instead of the upper end of the support column 21. Further, the lever 41 is not limited to the configuration in which the lock is released by rotation, and may be configured to release the lock by tilting back and forth or right and left.

  Thus, by providing the lock mechanism 40 that can lock the rotation of the rotating plate 30, it is possible to prevent the rotating plate 30 from rotating when the user does not intend, such as when the wheelchair C gets on and off. it can. Note that whether or not to provide the lock mechanism 40 is arbitrary, and the lock mechanism 40 may not be provided.

  The stoppers 50 are provided on both sides of the rotating plate 30 in the rotation direction, and restrict the rotation of the rotating plate 30 within a predetermined range. In the present embodiment, the stopper 50 is provided on the base 10 and is provided on both sides of the rotating plate 30 in the left-right direction. Further, block-shaped stopper abutting portions 34 are provided on both sides of the rotating plate 30 in the left-right direction. The stopper contact portions 34 are used to fix the vertical portions 24 to the rotating plate 30. The stopper contact portion 34 is disposed at a position where it comes into contact with the stopper 50 when the rotating plate 30 rotates. When the stopper abutting portion 34 abuts against the stopper 50, the rotation of the rotating plate 30 is locked to the stopper 50, thereby preventing the rotating plate 30 from rotating further.

  The stopper 50 is disposed so that the rotation is restricted when the rotating plate 30 rotates 30 ° clockwise and 30 ° counterclockwise in the direction around the central axis AX, for example. That is, the rotating plate 30 rotates in the range of 60 ° in the direction around the central axis AX. FIG. 8 is a plan view showing a state in which the rotating plate 30 is rotated. As shown in FIG. 8, the rotating plate 30 can rotate clockwise or counterclockwise in the direction around the central axis AX within a range in which the stopper contact portion 34 contacts the stopper 50. In addition, in FIG. 8, the state which the rotating plate 30 rotated counterclockwise is shown.

  Further, the rotation angle of the rotating plate 30 is not limited to 60 ° and can be arbitrarily set. Thus, by providing the stoppers 50 for restricting the rotation of the rotating plate 30 within a predetermined range on both sides in the rotation direction of the rotating plate 30, it is possible to restrict excessive rotation of the lower body of the user. Can do exercises that are appropriate for them. Further, the position of the stopper 50 can be changed, and the rotation angle of the rotating plate 30 can be changed.

  Next, how to use the exercise tool 100 configured as described above will be described. FIG. 9 is a diagram illustrating an example of a case where the exercise tool 100 is climbed onto the base 10 with the wheelchair C. First, as shown in FIG. 9, when the wheelchair C is mounted on the base 10, the user sitting on the wheelchair C moves the wheelchair C by holding the side portion 25 of the handrail 20 and pulls it. It can be easily moved onto the base 10 (rotary plate 30) by the person's own power.

  When there is a rope in the front portion 27 and the like, the user moves the wheelchair C in front of the exercise equipment 100 in advance and moves to the rear of the exercise equipment 100 while grasping the rope hanging from the front portion 27. By pulling this rope, the wheelchair C can be ridden on the base 10 from the guide portion 11. The user may ride on the wheelchair C on the base 10 by grasping the vertical portion 23 of the handrail 20 or the like. Further, the wheelchair C is not limited to the wheelchair C riding on the base 10 only by the user's power. Another assistant may push the wheelchair C and keep the wheelchair C riding on the base 10.

  When the user pulls the wheelchair C by himself / herself, the wheelchair C gets on the base 10, and the wheelchair C is disposed on the rotating plate 30. When the wheelchair C gets on the base 10, the rotation of the rotating plate 30 is locked by the lock mechanism 40. Moreover, after the wheelchair C gets on the base 10, a user operates the wheel stopper with which the wheelchair C is equipped, and it sets so that a wheel may not rotate. In addition, the rotation stop of the wheel of the wheelchair C may be provided in the rotating plate 30 etc. of the exercise tool 100, for example. Further, the handrail unit 20 and the wheelchair C may be coupled by a belt or the like to restrict the wheelchair C from moving on the rotating plate 30.

  FIG. 10 is a perspective view illustrating a state in which the exercise tool 100 is used and the state where the rotating plate 30 is not rotated. As shown in FIG. 10, in a state where the wheelchair C is disposed on the rotating plate 30, the user and the wheelchair C are in a state where the front and left and right directions are surrounded by the handrail portion 20. In addition, the user who got on wheelchair Cni can hold | grip the front holding part 22. FIG.

  FIG. 11 is a perspective view showing a state in which the rotating plate 30 is rotated in the usage mode of the exercise tool 100. FIG. 11 shows an example of exercise using the exercise tool 100. After placing the wheelchair C on the rotating plate 30, the user operates the lever 41 to unlock the rotating plate 30 by the lock mechanism 40. Subsequently, the user holds the grip portion 22 while sitting in the wheelchair C to support the upper body, and in this state, performs an operation of twisting the lower body clockwise or counterclockwise with respect to the upper body. By this twisting operation, a rotational force is transmitted from the wheelchair C to the rotating plate 30, and the rotating plate 30 rotates with respect to the base 10 in the direction around the central axis AX.

  As the rotating plate 30 rotates, the direction of the wheelchair C moves in the rotational direction, and the direction of the lower body of the user moves in the rotational direction with respect to the upper body. Thus, the exercise of twisting the lower body can be performed by the force of the upper body of the user sitting on the wheelchair C, and the user can perform the exercise of the upper body. When the rotating plate 30 is rotated by a predetermined angle (30 ° in the present embodiment) in the rotating direction, the rotation of the rotating plate 30 is restricted by the stoppers 50 arranged on both sides of the rotating plate 30 in the rotating direction. Thereby, since excessive rotation of the lower body is restricted, appropriate exercise can be continued.

  In addition, when the wheelchair C gets off from the base 10, the procedure reverse to the above is performed. That is, first, with the wheelchair C facing forward, the user operates the lever 41 and locks the rotation of the rotating plate 30 by the lock mechanism 40. Subsequently, the wheel stopper of the wheelchair C is removed and the wheelchair C is made movable. Subsequently, the user grasps the side portion 25 of the handrail portion 20 or grasps the vertical portions 23 and 24 of the handrail portion 20 and moves the wheelchair C toward the rear. Thereby, the wheelchair C moves from the exercise tool 100 to the floor F via the guide unit 11.

  As described above, the exercise tool 100 according to the present embodiment includes the rotating plate 30 that can rotate with respect to the base 10 and the support column 21 (gripping part 22) in a state where the wheelchair C is placed. Rotate the lower body together with the wheelchair C by the force of the upper body by riding on the rotating plate 30 of the base 10 while sitting in the wheelchair C, and twisting the lower body while holding the grip 22 and fixing the upper body Can do. By repeating this operation, the user who uses the wheelchair C can easily exercise the upper body, and can solve the lack of exercise of the upper body.
