BOTTOM STRUCTURE FOR CONTROLLING SUMMIT POSITION OF KNEE

摘要

PROBLEM TO BE SOLVED: To correspond with bending/stretching part of a user's body different in position according to the structure of the user's body. SOLUTION: A knee bottom 1a and reinforced frames 4, 5 of back surfaces side of a foot bottom 1b are rotatably connected through a junction frame 6. One end of a switch metal fitting 9 is rotatably assembled to a middle section of the junction frame 6, and other end of the switch metal fitting 9 is engaged to an engaging hole 10 provided at an adjacent connecting section to the junction frame 6 of the reinforced frames 4, 5 by a restricting pin. Since the junction frame 6 is mutually restricted by the reinforced frame 4 extended from a side of the knee bottom 1a and the reinforced frame 5 extended from the side of the foot bottom 1b, an entire curved center site (a knee position) can be switched.
