ABSTRACT:
The self-locking revolute joint can be adjusted at angles by turning an activation lever back and forth. It has a mount in which a bearing shaft rests rotatably in bearings, and supports an adjustment wheel which is provided with tooth profiles. The activation lever can be turned in both rotational directions around a turning axle resting in bearings in the mount; it has two swing-out carriers which do not engage with the adjustment wheel when the activation lever is in its central position; when the activation lever is turned, one of them engages with an adjacent tooth profile of the adjustment wheel and brings it to turn. Further, two locking arms rest rotatably in bearings at the mount and lock and adjustment wheel when the activation lever is in its central position. Each one of two radial cams arranged on the activation arm confunctions with a locking arm, via a release arm. When the activation lever is turned out of the central position, one radial cam brings the related release arm along and thus disengages the locking arm in the momentary drive direction.
