Wearable muscular-force supplementing device

摘要

A muscular-force supplementing device (2) of the present invention includes an artificial muscular-force generating section (4) and a control section (6) for controlling the driving of the artificial muscular-force generating section (4). The artificial muscular-force generating section (4) is composed of a pair of mounting portions (8a) and (8b) worn at two positions on both sides of a wrist joint of the user, and an actuator (10) hinged on connecting portions (8a1) and (8b1) of the mounting portions (8a) and (8b). The actuator (10) is a device having therein a plurality of hydraulic cylinders to be operated in a dual-stroke manner. When hydraulic oil serving as the fluid is supplied to pressure chambers, a pair of piston rods are extended, and linear actuator force is transmitted to the connecting portions (8a1) and (8b1) of the mounting portions (8a) and (8b), thereby transmitting bending force to the joint of the user. <IMAGE>
