ABSTRACT:
A door lock has a flush-mountable body. A forwardly facing recess is defined by the body. A push-button actuator for operating the lock is carried by the body and is movable between normal and operating positions. A bolt is carried on the back of the body and is movable between latching and unlatching positions. A key-controlled disconnect linkage is provided for selectively drivingly connecting and disconnecting the actuator and the bolt. The disconnect linkage includes a disconnect member which is moved by a key-operated locking member between connecting and disconnecting positions located, respectively, in and out of the path of travel of a latch bolt operating arm. When the disconnect linkage drivingly connects the actuator and the bolt, movement of the actuator from its normal position to an operating position will cause corresponding unlatching movement of the bolt. When the disconnect linkage disconnects the actuator from the bolt, movement of the actuator is inoperative to cause unlatching movement of the bolt. A feature of the disconnect linkage is that it provides the lock with a "slam" capability, meaning that the bolt can be slammed into latching engagement with a suitably configured strike regardless of whether the disconnect linkage is drivingly connecting or disconnecting the actuator and the bolt.
