Abstract

A locking mechanism comprises a casing (10) in which two followers (13, 30) are mounted for angular movement, the followers being directly connected to a common sliding drive link (58) by respective links (22, 36), with lost motion between each follower and its associated link. A latchbolt (46, 49) is biased to extend from the casing, being retractable by an actuator (41) operated by movement of one of the followers (13), whilst a hookbolt (22) constituting one of the links is moved into or out of the casing by movement of that one of the followers. The drive link is slidable to an operative position, where it can actuate upper and lower secondary locking members, and in the operative position the hookbolt is extended from the casing. The drive link can be locked against release from the operative position by actuation of a key operated cylinder lock, such locking also retaining the hookbolt in its extended position.
