Further, the other end portions on both sides of the pipe material 37 of the lower frame member 25 are bent into a substantially L shape and protrude toward the front side of the support body 21 . As shown in FIG. 5, a base plate 50 forming a footrest is attached by screws 51 to the intermediate portion of the pipe material 37 which continues to the other ends on both sides. A rubber mat 53 having a large number of protrusions 52 is attached to the upper surface of the substrate 50. Furthermore, a holder 54 for holding the user's ankle is provided on the upper surface of the base 50. This holder 54 is made by bending a plate material into a substantially semicircular shape, and has a fixed part 56 with an elastic material 55 attached to the inner surface and a movable part 57, and one end in the circumferential direction is connected to a hinge 58 as shown in FIG. Therefore, it is pivoted. A pair of mounting pieces 59 extend from the lower end of the fixed portion 56 in the axial direction perpendicular to the circumferential direction, and these mounting pieces 59
is attached to the substrate 50 by the screws 51. Note that since the mat 53 is interposed between the mounting piece 59 and the board 50, this mat 5

Moreover, flanges 60 and 61 as regulating parts are formed at the upper ends of the fixed part 56 and the movable part 57 over the entire length in the circumferential direction. Furthermore, the movable part 57 is connected to the fixed part 5 by the connecting tool 62.
6 and is fixed unrotatably. This connector 62 is
It consists of a rectangular frame-shaped ring 63 whose one end is pivotally attached to the other end in the circumferential direction of the movable part 57, and a lever 64 whose one end is pivotally attached to the other end in the circumferential direction of the fixed part 56. A plurality of recesses 65 are formed on the side surface. Therefore, the other end of the ring 63 is engaged with the recess 65 and the lever 64 is fixed to the fixing part 56.
The movable part 57 can be fixed to the fixed part 56 by rotating it in the direction in which it joins to the outer peripheral surface of the movable part 57. Further, at this time, the other end of the movable part 57 overlaps with the outer surface of the other end of the fixed part 56, and a part of the flange 61 of the movable part 57 enters under the flange 60 of the fixed part 56. Therefore, the movable portion 57 is prevented from shifting in the direction indicated by arrow B in FIG.

In the support body 21 having such a structure, as shown in FIG. 1, the other end of a connecting pipe 28 provided on the intermediate frame member 23 is rotatably connected to the mounting plate 4. That is, as shown in FIG. 8, a mounting hole 65 is bored in the mounting plate 4, and a shaft-shaped nut 29 provided at the other end of the connecting pipe 28 is rotatably inserted into this mounting hole 65. There is. A screw 66 is screwed into this nut 29 via a washer 67 to prevent the nut 29 from coming off from the mounting hole 65. Furthermore, one connecting pipe 28
At the other end, as shown in FIGS. 8 and 9, a strip plate 69 forming a stopper mechanism 68 is fixedly attached at one end. A cylindrical body 70 is attached to the other end of this strip plate 69, and a stopper shaft 71 is inserted through this cylindrical body 70. This stopper shaft 71
is a through hole 73 whose one end is bored in the strip plate 69 by a spring 72 housed in the cylindrical body 70;
It is biased in the direction that it protrudes from. When the support body 21 is in the state shown in FIG. 1, that is, in a state tilted in the backward rotation direction rather than vertically, one end of the stopper shaft 71 enters the locking hole 74 bored in the mounting plate 4. , to prevent rotation of the support body 21. Note that when the support body 21 is in the state shown in FIG. There is.

Next, a method of using the exercise equipment having the above structure will be explained. First, the support 21 is brought into a state where its rotation is prevented by the stopper mechanism 68, as shown in FIG. This state of the support body 21 is referred to as a normal state in this specification. Once the support body 21 is held in the normal state, the user stands on the mat 53 of the base plate 50, holds both ankles by the pair of holders 54, and holds the back of the user on the support body 2, as shown in FIG.
1 sheet 42. Next, the user pulls the stopper shaft 71 of the stopper mechanism 68 to remove one end thereof from the locking hole 74 of the mounting plate 4. Then,
Since the support body 21 is rotatable relative to the leg body 1, the user grasps the grip part 9 of the mounting plate 4 with both hands,
If the support body 21 is rotated by oneself in the backward rotation direction shown by arrow C in FIG. 11, the user will assume a handstand position with the head down and the feet up, as shown by the chain line in FIG. 11. Can be done. Therefore, by continuing this handstand posture for a predetermined period of time, drooping of the internal organs can be prevented. Also, if you repeatedly stand in a handstand position and then in a normal position, you can improve blood circulation in your body and activate your metabolism.

Furthermore, when the user assumes a handstand posture, the movable portion 57 of the holder 54 is pressed in the axial direction indicated by arrow B in FIG. 5 by the instep of the user's foot. Then, the movable part 57 tries to shift, but since the flange 61 of the movable part 57 hits the flange 60 of the fixed part 56, the movable part 57 is prevented from moving in the direction of the arrow B. Therefore, the holder 54 not only securely holds the user's ankle, but also prevents undue force from being applied to the hinge 58 that pivotally connects the movable part 57 to the fixed part 56. Further, since the holder 54 swings in the direction shown by arrow A in FIG. 5 due to the elasticity of the mat 53, the holder 54 does not apply unreasonable force to the user's ankle. Further, in the normal state, the soles of the user's feet are massaged by the protrusions 52 of the mat 53 attached to the upper surface of the board 50.

Furthermore, when the exercise equipment is not used, the overall height can be reduced by removing the upper frame member 24 from the intermediate frame member 23 of the support body 21.
Further, by rotating the movable leg 8 of the leg body 1 in the direction of the fixed leg 6 shown by arrow D in FIG. 11, the dimension in the front-rear direction, that is, the depth dimension of the leg body 1 can be reduced. Furthermore, by pushing the rod material 12 of the leg body 1 into the inside of the pipe material 11, the height dimension of the leg body can also be reduced. Therefore, these things allow exercise equipment to be made smaller.
Convenient to carry and store.

In addition, in this invention, the restricting part that restricts the movement of the movable part of the holder in the axial direction is not limited to the flange, but is essentially provided on the fixed part and the movable part of the holder, and the restricting part that restricts the axial movement of the movable part of the holder is Any structure may be used as long as the movable parts are opposed to each other and restrict movement in the axial direction when the movable parts are coupled to the fixed part.

As described above, this invention consists of a holder that holds the user's ankle, a fixed part, a movable part whose one end in the circumferential direction is pivotally connected to the fixed part, and the other end of the movable part in the circumferential direction fixed to the fixed part. The movable part is configured to include a connector that is coupled to the part, and a restriction part that restricts movement of the movable part in an axial direction perpendicular to the circumferential direction. Therefore, even if a large load is applied to the holder when the user performs a handstand exercise, the movable part will not shift due to this load, and the user's ankle will be held in a stable state. Not only is it stable, but the holder will not be damaged due to excessive force being applied to the pivot joint between the movable part and the fixed part.
