DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of a leg fixing device for an automatic inversion machine according to the present invention. FIG. 1 is a partially cutaway front view of essential parts of the present invention, and FIG. 2 is a partially enlarged view of FIG. 3 is a side view of FIG. 1, and FIG. 4 is a front view of the automatic inversion machine.

In the automatic inversion machine of the embodiment, a bearing 2 is installed on the upper end of a gantry 1, and a crank-shaped main shaft 4 provided at an intermediate portion of a rotary base 3 is rotatably supported by the bearing 2 and the main shaft 4 is rotatably supported.
By rotating the turntable 3 around the center, a person on the turntable can freely perform an inverted operation.

A holding cylinder 5 is attached to a main board 3a which constitutes the turntable 3.
The adjustment rod 6 is attached to the holding cylinder 5 so that the adjustment rod 6 can be freely extended and retracted (the length of the rotary table 3 is adjusted to match the height of the user), and the length of the rotary table 3 is adjusted at the tip of the adjustment rod 6. The support cylinder 7 is fixed in a direction orthogonal to the support cylinder 7, and the leg receiving member 8 is mounted on the adjusting rod 6 near the support cylinder 7.

The leg receiving member 8 is composed of a main rod 9 and leg receiving portions 10, 10 located on both sides of the main rod 9 in the left-right direction,
The main rod 9 is passed through the adjusting rod 6, and the tip of a screw 11 screwed onto the adjusting rod 6 is pressed against the circumferential side of the main rod 9 to support the main rod 9 on the adjusting rod 6, and the main rod 9 is supported. On the foot rest 1
0 and 10 are fitted and assembled, and the leg receiving portion 10 is configured by combining the elastic body 10b with the base frame 10a and using the elasticity of the elastic body 10b to place it in the proper position on the main rod 9.

FIG. 12 shows a leg holding member having a leg holding portion 13 corresponding to the leg receiving portion 10 of the leg receiving member 8. The leg holding member 12 is provided with a connecting rod 15 at the center of a main rod 14. The left and right leg holding portions 13 and 13 formed by combining a base frame 13a having the same structure as the leg receiving portion 10 and an elastic body 13b on both left and right
It is configured by fitting.

A plurality of locking holes 16 are provided in a row on the circumferential side of the connecting rod 15 of the leg holding member 12, and the side surfaces of the locking holes 16 are provided in the support cylinder 7 so as to match the locking holes 16. Access hole 17
Insert the connecting rod 15 into the support cylinder 7 toward and away from the side,
A first coil spring 18 is stretched between the support cylinder 7 and the connecting rod 15 to urge the connecting rod 15 to move in the insertion direction.

Reference numeral 19 denotes a guide cylinder projectingly provided on the support cylinder 7 so as to surround the entrance / exit hole 17, and the guide cylinder 19 supports the locking rod 20 whose tip enters and exits the entrance / exit hole 17,
The second coil spring 21 in which the locking rod 20 is wound and housed in the guide cylinder 19 is interposed between the collar piece 20a provided on the locking rod 20 and the tip end piece 19a of the guide cylinder 19, and the tip of the locking rod 20 is The second coil spring 21 is biased so that the second coil spring 21 is locked in the locking hole 16 through the entrance / exit hole 17.

A knob 22 is provided on the base portion of the locking rod 20 projecting from the guide cylinder 19.

In the figure, 23 is a foot rest member, which is the foot rest member 2
The reference numeral 3 designates a support rod 7 extending from the support rod 7 through the support rod 7 and a footrest rod 25 connected to a support rod 24 which is inclined and projected.

However, when the locking rod 20 is moved in the direction in which it is pulled out from the guide cylinder 19 against the bias of the second coil spring 21 by the knob 22, the tip of the locking rod 20 is locked by the locking hole 1
6, and at this point, the connecting rod 15 of the leg holding member 12 can be moved from the support cylinder 7 in the pull-out direction against the first coil spring 18. Then, from the support cylinder 7 to the connecting rod 14
The part is pulled out for an appropriate length to release the holding state of the knob 22 by the hand, the tip of the locking rod is locked in the appropriate locking hole 16 through the access hole 17, and the leg of the experienceer is placed on the leg receiving part 10. When the knob 22 is placed and pulled, the urging force of the first coil spring 18 functions to move the connecting rod 15 inward of the support cylinder 7, and the leg is held between the leg receiving portion 10 and the leg holding portion 13. When the holding state of the knob 22 is released at this point, the tip of the locking rod 20 is locked in the locking hole 16 through the insertion / exit hole 17, and the leg fixing state by the leg receiving portion 10 and the leg holding portion 13 is secured.

[0015]

[Effect of the Invention] Since the present invention is configured as described above,
Fix the legs by using the biasing force of the first and second coil springs.
The releasing operation can be performed smoothly and easily.
