Abstract
Official abstract text for this publication.
A multi-articulated link knee joint includes: a knee unit in which an upper link unit rotates relative to a lower link unit by a multi-articulated link mechanism including a plurality of link units including the upper link unit and the lower link unit; a cylinder device for assisting the motion of the knee unit and moving in accordance with the rotation of the upper link unit; a position detector for detecting the distance from the lower link unit to the cylinder device; and an angle detector for obtaining the bending angle of the knee unit from the detected distance from the cylinder device.
First claim
Opening claim text (preview).
What is claimed is: 1. A multi-articulated link knee joint comprising: a knee unit in which an upper link unit is structured to rotate relative to a lower link unit by a multi-articulated link mechanism including a plurality of link units including the upper link unit, the lower link unit, and an additional link unit for coupling the upper link unit and the lower link unit; an auxiliary driver structured to assist motion of the knee unit and to move in accordance with rotation of the upper link unit; a position detector structured to detect a relative position of the auxiliary driver relative to the lower link unit; and an angle detector structured to obtain a bending angle of the knee unit from the detected relative position of the auxiliary driver, wherein the position detector detects a distance from the lower link unit to the auxiliary driver as the relative position of the auxiliary driver, and the angle detector obtains a bending angle of the knee unit from the detected distance. 2. The multi-articulated link knee joint according to claim 1 , wherein the position detector and the angle detector are provided in the lower link unit.
