Abstract

A lock has a primary unit (10, 11) from which top and bottom actuator strips (12, 13) are extended or retracted to lock or release upper and lower secondary locking units, the primary unit including two non-coaxial spindle operable follower assemblies (19, 20), each of which is operable to slide a bottom actuator plate (27) and thereby retract or extend the strips (12, 13), a latch bolt (22), movable between respective extended and retracted positions by one of said follower assemblies (19) and also by an actuating mechanism (47, 50), a deadbolt (18), movable between respective extended and retracted positions by a further, key operated actuating mechanism, and the bottom actuator plate (27) preventing retraction of the latch bolt (22) unless the secondary locking units are in their respective retracted positions. <IMAGE>
