ABSTRACT:
A door lock has a flush-mountable body. A forwardly facing recess is defined by the body. A paddle-type handle is pivotally carried by the body and is movable between a nested position within the body recess and an operating position. A spring-projected slide bolt is carried on the back of the body and is movable between projected and retracted positions. A key-controlled disconnect linkage is provided for selectively connecting and disconnecting the handle and the bolt. The disconnect linkage includes a rotatably-mounted disconnect member which extends longitudinally relative to the bolt. Interengageable formations are provided on the bolt and the disconnect member. The interengageable formations are brought into and out of driving engagement by the movement of a key-operated locking member. When the disconnect linkage drivingly connects the handle and the bolt, movement of the handle from its nested position to an operating position will cause corresponding retracting movement of the bolt. When the disconnect linkage disconnects the handle from the bolt, movement of the handle is inoperative to cause retracting movement of the bolt. A feature of the disconnect linkage is that it provides the lock with a "slam" capability, meaning that when the bolt is projected, it can be slammed into latching engagement with a suitably configured strike regardless of whether the disconnect linkage is drivingly connecting or disconnecting the handle and the bolt.
