Accordingly, the chest is not compressed by the holder 35 when the person A requiring assistance stands, and the person A requiring assistance can be erected without causing discomfort. Furthermore, since the footrest 7 moves in the horizontal direction, the legs move backward when the person A requiring assistance stands up, and the posture of the person A requiring assistance when standing up becomes stable. As a result, the burden on the person A in need of standing is reduced.

  The rotation of the holder 35 in the backward direction is restricted at a predetermined position, and the holder 35 does not rotate in the backward direction beyond a certain angle. Accordingly, when the body of the person A requiring assistance is about to fall backward, the rotation of the holder 35 is restricted, and the person A requiring assistance can be prevented from falling backward. Further, since the holder 35 that holds the body of the person A requiring assistance in the standing state is always urged to rotate in the forward rotation direction, the body of the person A requiring assistance is slightly inclined forward. As a result, the standing posture of the person A requiring assistance can be stabilized.

And a cylindrical lower rotating member 105 is provided. A plurality of biasing members 106 made of a spring extending in the vertical direction are interposed between the rotation upper member 104 and the standing assisting device main body 103, and the rotation upper member 104 is biased downward by the biasing member 106. Has been. A plurality of holes 107 are formed along the circumference on the upper surface of the rotating upper member 104, and the pins 108 suspended from the lower surface of the standing assisting device main body 103 are movable up and down in the plurality of holes 107, respectively. Loosely inserted. Further, a hooked portion 109 projecting sideways is formed on the outer peripheral surface of the rotating upper member 104, and the hooked portion 109 is suspended from the lower surface of the standing assisting device main body 103. The member 110 is hooked. The hooking member 110 is provided with a hook that is hooked to the hooked portion 109, and is attached to be rotatable in the vertical direction.

 Further, a circular convex portion 111 whose diameter increases downward is formed at the lower portion of the rotating upper member 104, and a plurality of freely rotatable balls 112 are formed on the lower surface of the rotating upper member 110 around the convex portion 111. It is provided at equal intervals. A concave portion 113 is formed on the upper surface of the rotating lower member 105 in accordance with the shape of the convex portion 111, and the convex portion 111 is fitted into the concave portion 113. An annular groove 114 on which the ball 112 slides while rotating is formed on the upper surface of the rotating lower member 105 around the recess 113. A disk-shaped grounding portion 101 is joined to the lower surface of the rotating lower member 105.

  According to the rotation fulcrum 102 having such a configuration, when the latching member 110 is rotated upward to remove the latching member 110 from the latched portion 109, the rotation upper member 104 is moved downward by the biasing member 106. The rotating lower member 105 moves downward, and the grounding unit 101 contacts the floor. Further, since the rotation upper member 104 and the rotation lower member 105 are attached by fitting the circular convex portion 111 and the concave portion 113, the rotation upper member 104 can be rotated on the rotation lower member 105 in the horizontal direction. Become. For this reason, when the standing assisting device main body 103 is rotated in the horizontal direction, the pin 108 is loosely inserted into the hole 107, so that the rotation upper member 104 is rotated in cooperation with the standing assisting device main body 103, and the rotation fulcrum base The standing assisting device main body 103 can be rotated about the fulcrum 102.

 In the above-described embodiment, the guide column 15 is formed in an arcuate shape, but the present invention may use a guide column that extends straight and obliquely, or a guide column that is bent in a dogleg shape. The shape of the guide column may be changed as appropriate. In the above-described embodiment, the guide column 15 is formed from a single steel pipe, but the present invention configures the guide column by rotatably connecting a plurality of guide members, and changes the shape. It may be a guide pillar that can Alternatively, the guide pillar 15 may be removable and can be replaced with a guide pillar of several types. Thereby, the shape of the guide column can be easily changed, and the holder 35 can be moved in accordance with the person requiring assistance A by forming the guide pillar according to the person A requiring assistance.

 Moreover, although the above-mentioned embodiment demonstrated the case where the person A requiring assistance sitting on the wheelchair 1 was stood up, this invention makes it sit on the edge of the bed of the person A requiring assistance sleeping on the bed, for example.
