Title:
KNEE JOINT
Document Type and Number:
WIPO Patent Application WO/2018/087997
Kind Code:
A1
Abstract:
The present invention provides a small and light knee joint that has good energy efficiency and is able to move in a wider movement range. The present invention also provides a comparatively cheap, active knee joint. A drive unit 1 moves a driven member 21. An elastic member 22 is disposed between the driven member 21 and a linear motion unit 23. The linear motion member 23 elastically moves via the elastic member 22 in at least one direction as the driven member 21 moves. A crank mechanism 3 converts linear motion of the linear member 23 to rotational motion, thereby allowing the knee joint to bend and straighten.
