ABSTRACT:
A lock intended primarily for gliding or hinged doors or windows. The lock is an improvement over the prior art in that it is a very simple mechanism which nonetheless is secure and cannot be back-driven. The lock mechanism is made up of essentially two parts: a cam gear which is rotatably mounted on a housing and acts as an actuator, and a cam rack which is linearly slidable relative to the housing. Rotation of the cam gear causes the cam rack to move between an unlocked and a locked position. Once in the locked position, a gear tooth of the cam gear engages with a stop surface on the cam rack to prevent the cam rack from being back-driven.
