PROBLEM TO BE SOLVED: To enable the heel to be kept high without bending the knee by dispersing stress in such a manner that the calf is equally held, to reduce burden of the leg, and to keep the state for long hours.SOLUTION: The raising angle 10 of this lower limb holding device is determined under a state being in contact with the equal load angle 11 of the calf, and also, being in contact with a floor surface 13. The raising angle 9 of the leg is determined by the raising angle 10, the equal load angle 11 of the calf which is an individual eigenvalue, and reference lines 4 and 7 which are the bending angle of the knee joint and the length of the leg. Therefore, the lower limb holding device stays still with balance at the angle by which the calf is equally held, and can hold the heel to be high without bending the knee.COPYRIGHT: (C)2012,JPO&INPIT【課題】膝を曲げずにかかとを高く保つことを、ふくらはぎを均等に保持することによって応力分散し、脚の負担を軽減させ、長時間持続する。【解決手段】下肢保持具の上げ角10は、ふくらはぎの均等荷重角11沿って接し、また床面13に接した状態で決定する。脚の上げ角9はこの上げ角10と、個人固有値である、ふくらはぎの均等荷重角11、ひざ関節の曲がり角および脚の長さである基準線4と7で決定されるので、下肢保持具は、ふくらはぎを均等に保持する角度でバランス静止し、膝を曲げずにかかとを高く保持できる。【選択図】図2
