The pelvic correction device shown in FIGS. 1 and 2 has a rectangular bed 1 on which a human body M lies. The bed 1 is supported by four legs 2 provided at the corners of the lower surface, and these legs 2 are reinforced by a cross bar 3 laid between the adjacent legs 2.
[0017]
In the width direction on the bed 1, a pair of pillars 4 formed in a hollow quadrangular pillar shape are erected at intervals such that the waist of the human body M can be interposed. An upper rail 5 is hung horizontally between the columns 4, and both ends of the upper rail 5 are fixed to upper ends of the pair of columns 4 by bolts 13, respectively.
[0018]
A push rod 7 whose one end is directed to the waist of the human body M is supported at an intermediate position of the support column 4 so as to be inclined obliquely from above. One end of the push rod 7 has a pressing force against the waist of the human body M. Is provided, and a gripper 6 is attached to the other end. The contact surface of the pressing member 8 with the waist of the human body M is formed in a spherical shape so as to reduce the feeling of pressure when the waist of the human body M is pressed.
[0019]
A belt-like rubber 9 is laid between the pair of push bars 7 as urging means, and both ends of the belt-like rubber 9 are attached to the other ends of the pair of push bars 7 respectively. That is, when the human body M lays down, the belt-like rubber 9 is attached in a stretched state so that each push rod 7 can press the waist of the human body M. The length of the push rod 7 is also set to a length that can be reliably pushed regardless of the size of the human body M. The urging means is not limited to the belt-shaped rubber 9, but may be any as long as it can appropriately apply an urging force to the push rod 7, and a spring or the like may be attached.
[0020]
3 and 4, slits 4c and 4d extending in the up-down direction are formed in the opposing side walls 4a and 4b of the column 4, respectively, as shown in FIGS. Inside, a block 10 made of aluminum having a through hole 10a penetrating obliquely toward the waist of the human body M is mounted so as to be movable in the vertical direction.
[0021]
The push rod 7 is inserted into the slits 4c and 4d and the through hole 10a so as to be slidable in the axial direction, that is, the push rod 7 is inclined toward the waist of the human body M at an angle θ. It has become. In this case, since the through hole 10a guides the axial movement of the push rod 7, the inner diameter thereof is set to a size that allows the push rod 7 to slide and does not rattle. Is preferred. The angle θ is set to an angle at which the waist of the human body M can be pressed in a substantially right angle direction.
[0022]
A plate 12 is arranged on the outer surface of the slit 4c so as to straddle the slit opening in the width direction, and the plate 12 is fastened to the block 10 via the slit 4c by a screw 11, and the block 10 is fixed to the column 4 Have been. That is, the push rod 7 is positioned and fixed at a desired height position by sandwiching the open end of the slit 4c of the support 4 between the plate 12 and the block 10.
