Title:
MOVABLE PROSTHETIC HAND
Document Type and Number:
Japanese Patent JP2016054915
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a movable prosthetic hand that can easily grip an object by a sense being almost a healthy hand.SOLUTION: A supporting member 41 is fixed in the front end of a palm part 10. A first bone member 42 is connected to the supporting member 41 bendably in a fulcrum c1 to the palm part 10. A second bone member 43 is connected to the first bone member 42 bendably in a fulcrum c2 to the first bone member 42. The tip of a wire rod W is fixed to a fixing part j installed in the second bone member 43. The wire rod W is slidably guided by a guide unit g installed in the first bone member 42 so that the wire rod W goes to the palm part 10 side. The fixing part j and the guide unit g are disposed so that a first rotational moment M1 around the fulcrum c1 acts on the first bone member 42 and a second rotational moment M2 around the fulcrum c2 acts on the second bone member 43, and the first rotational moment M1 becomes larger than the second rotational moment M2, when the wire rod W is towed from the palm part 10 side.SELECTED DRAWING: Figure 5
