摘要： The object of the invention is to create a self-locking joint, in particular an orthotic joint, which may be unlocked with little effort, so that even handicapped patients may be able to unlock the joint. For that purpose, the joining pieces (1, 2) have curved profiles (5, 6) that cross each other at such a large angle that a rolling body (7) guided in both curved profiles (5, 6) and whose axis lies at the intersection between the median lines (10, 11) of the curve profiles (5, 6) moves freely along the median lines (10, 11) of the curved profiles (5, 6) when one joining piece (1, 2) rotates against the other. A self-locked state of the joint is reached when the alpha angle between imaginary tangents to the median lines (10, 11) applied to their intersection approaches zero and the line that connects the centres of the curvature circles of both curved profiles (5, 6) does not extend through the axis of rotation (4) of the joint in the crossing or contact point in the locked position.
