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 mounting member which extends longitudinally along one side of the bolt and which is drivingly engaged by the handle. A disconnect member is supported on the mounting member and is arranged to be pivoted from side to side between connecting and disconnecting positions by the movement of a key-operated locking member. When the disconnect member is in its disconnecting position, the disconnect linkage makes no driving connection between the handle and the bolt, whereby movement of the handle causes no corresponding movement of the bolt. When the disconnect member is in its connecting position, the disconnect linkage provides a driving connection between the handle and the bolt, whereby movement of the handle from its nested position to an operating position will cause corresponding 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.
