ABSTRACT:
An exercise assisting instrument assists the user's knee-bending exercise, and lightens a burden and maintains safety of the user. It has a base10, supporting columns20, lifting mechanisms30consisting of lifting arms, lever arms40, and a chair50. A three-member linkage system is formed by the supporting columns20and the lifting mechanisms30, so that the chair50may move upward and downward. Further, it is equipped with an upward movement assisting device33, which provides a force in the raising direction to the hinge point30aof the lifting arms, so that stand-up movement of the user is assisted and lightening the user's burden is possible. Moreover, a locking device11and a stopper13are equipped, so the user's safety may be improved.
