Summary: | To provide a walking auxiliary device that enables natural walking motion.SOLUTION: A hydraulic artificial leg 1 comprises: a hydraulic cylinder 7 that is provided between a support member 2 attached to a user's femur and a lower thigh member 3 and contracts when the lower thigh member 3 rotates in a flexion direction with respect to the support member 2; a hydraulic cylinder 8 that is provided between the lower thigh member 3 and a foot member 4 and contracts when the foot member 4 rotates in a dorsal flexion direction with respect to the lower thigh member 3; and a first communication passage 101 that makes a piston side chamber 74 for discharging liquid when the hydraulic cylinder 7 contracts communicate with a piston side chamber 84 for discharging liquid when the hydraulic cylinder 8 contracts.SELECTED DRAWING: Figure 1
【課題】自然な歩行動作をとることが可能な歩行補助装置を提供する。【解決手段】油圧義足1は、使用者の大腿部に取り付けられる支持部材2と下腿部材3との間に設けられ、支持部材2に対して下腿部材3が屈曲方向に回動すると収縮する油圧シリンダ7と、下腿部材3と足部材4との間に設けられ、下腿部材3に対して足部材4が背屈方向に回動すると収縮する油圧シリンダ8と、油圧シリンダ7が収縮するときに液体を排出するピストン側室74と油圧シリンダ8が収縮するときに液体を排出するピストン側室84とを連通させる第1連通路101と、を備える。【選択図】図1 |
