Abstract

See full text

A mortise lock is provided including a housing for a latch bolt and a deadbolt which are mounted in the housing for movement between a retracted position where the latch bolt and deadbolt are inside the housing and an extended position where a portion of the latch bolt and deadbolt extend from the housing. A key-operated cylinder in the housing operates to move the deadbolt between the retracted and extended positions. A latch operator is also provided for retracting both the latch bolt and the deadbolt. A moveable blocking element in the housing prevents movement of the latch operator in one position of the blocking element. A locking lever operatively connects the deadbolt and the blocking element so that when the deadbolt is extended the blocking element is automatically moved to the position blocking the latch operator. The locking lever comprises an arm member integral with the locking lever. A latch lever operatively connects the key-operated cylinder and the arm member of the locking lever when the blocking element is in the blocking position for moving the blocking element out of the blocking position by operation of the key-operated cylinder.
