PROBLEM TO BE SOLVED: To provide a miniaturized and lightweight hand exoskeleton deice to be attached to a finger of a human body and capable of supporting a user in activities of daily living.SOLUTION: A hand exoskeleton device has a three-layered connected sliding spring mechanism, wherein flexible springs are disposed in three layers and motions are changed by one driving means. With this structure, power is transmitted to the metacarpophalangeal joint (the MP joint), the proximal phalangeal joint (the PIP joint) and the distal phalangeal joint (the DIP joint) of a finger other than the thumb, so that activities in daily living can be supported. According to this invention, a miniaturized and lightweight device for supporting the gripping motion of fingers of the human body can be provided. This invention is characterized by that the bending and stretching of three joints of a finger can be driven by one driving means and that large drive force can be transmitted. Further, the device can be safely driven because of the flexibility of a device body. |
