Abstract: A latch gear lock device adapted to releasably secure together relatively movable members has a base and a latch bolt member pivotally mounted on the base. The latch bolt member has a dentate surface, a cam surface and means for receiving a keeper. A latch gear means pivotally mounts on the base for governing movement of the latch bolt member from an unlatched position to a latched position and for providing selected latch positions between the unlatched and latched positions. A biased release means extends through the base and provides for selectively releasing the latch bolt member to its unlatched position.

Abstract: A locking mechanism for locking menbers, such as slidable or swingable closures, to another, usually stationary, member in closed position in which a bracket on the stationary member is engageable by a hook on the closure member to latch the members together while actuation of the hook into a position of disengagement from the bracket to unlock the members from each other is accomplished by a key operated push lock mechanism.
