walking supporting device

The present invention discloses a muscular strength assisting device, which enables muscular strength to be assisted by storing truncus kinetic energy without performing a motor-operated muscular strength assisting process with respect to a case that motor-operated assistance is not necessary anymore due to rehabilitation by muscular strength assistance or a partial joint where a muscular strength assisting degree of each joint does not depend on electric motion. According to an embodiment of the present invention, the muscular strength assisting device includes: a waist protection unit (110) which enables the waist to be supported; a direction changing unit (120) which is installed in both sides of side surfaces of the waist protection unit (110) to enable the waist protection unit (110) to be tilted in a vertical direction and rotated in a horizontal direction; a hip joint unit (130) which is coupled to the direction changing unit (120) such that the direction changing unit (120) and one end of the hip joint unit (130) can be rotated in a lateral direction, can rotate a hip joint of a human body in forward and backward directions, and can assist muscular strength by using elastic forces of springs; a knee joint unit (140) which is connected to the hip joint unit (130) through a hip joint link (142), can rotate a knee joint of the human body in the forward and backward directions, and can assist muscular strength by using elastic forces of the springs; a calf support unit (150) which is connected to the knee joint unit (140) through a knee joint link (152) and is provided with a calf support (154) for covering up calf of the human body; and an ankle joint unit (160) which is connected to the calf support unit (150) and can support feet of the human body. 본 발명은 근력보조기가 개시된다. 본 발명의 일 실시예에 따른 근력보조기는 허리를 지지할 수 있도록 한 허리보호부(110)와, 상기 허리보호부(110)의 측면 양측에 상하방향으로의 틸팅 및 수평방향으로 회전될 수 있도록 한 방향전환부(120)와, 상기 방향전환부(120)와 일단이 측방향으로 회동가능하게 결합되며 신체의 고관절을 전후방향으로 회동시킬 수 있으며 스프링의 탄성력을 이용하여 근력을 보조할 수 있는 고관절부(130)와, 상기 고관절부(130)와 고관절링크(142)를 통해 연결되며 신체의 슬관절을 전후방향으로 회동시킬 수 있으며 스프링의 탄성력을 이용하여 근력을 보조할 수 있는 슬관절부(140)와, 상기 슬관절부(140)와 슬관절링크(152)를 통해 연결되며 신체의 종아리를 감쌀 수 있도록 한 종아리지지대(154)가 마련된 종아리받침부(150) 및 상기 종아리받침부(150)와 연결되며 신체의 발을 지지할 수 있도록 한 족관절부(160)를 포함하는 근력보조기가 제공된다.
