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 disconnect member which extends longitudinally along one side of the bolt and which has an end region that is shifted from side to side between connecting and disconnecting positions by 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.

A door lock, comprising: (a) a body structure defining an elongate bolt-mounting passage therein; (b) a bolt structure positioned at least partly in the passage for movement between latching and unlatching positions, the bolt structure having a connecting formation connected thereto for movement along a first path of travel within the passage in response to movement of the bolt structure between its latching and unlatching positions; (c) a handle structure connected to the body structure for movement between normal and operating positions, the handle structure having an operating formation connected thereto for movement along a second path of travel within the passage in response to movement of the handle structure between its normal and operating positions; (d) key control means connected to a selected one of the structures and having a locking member which is movable relative to the selected structure between locked and unlocked positions, the key control means being operable to selectively retain the locking member in its locked and unlocked positions; (e) disconnect means interposed between the operating formation and the connecting formation for selectively drivingly connecting and disconnecting the operating and connecting formations to thereby selectively drivingly connect and disconnect the handle and bolt structures, the disconnect means including a disconnect member housed at least partly within the passage, and mounting means supporting: (i) only a part of the disconnect member for movement within the passage along a third path of travel between connecting and disconnecting positions in response to movement of the locking member between its locked and unlocked positions; and, (ii) the entire disconnect member for movement along a fourth path of travel paralleling the length of the elongate passage in response to movement of the operating formation along the second path of travel; (f) the disconnect means being operable: (i) when the part of the disconnect member is in its connecting position, to drivingly connect the handle and bolt structures such that, when the handle structure is moved to its operating position, the bolt structure is caused to move to its unlatching position; and, (ii) when the part of the disconnect member is in its disconnecting position, to provide no driving connection between the handle and bolt structures, whereby the handle structure may be moved freely between its normal and operating positions and the disconnect member may be moved freely along the fourth path of travel without causing corresponding movement of the bolt structure; and, (g) the mounting means being operable to translatably mount the entire disconnect member for linear movement along the fourth path of travel longitudinally with respect to the passage, whereby the fourth path of travel is caused to take the form of a linear path, paralleling the length of the elongate passage, and the mounting means being operable to confine the third path of travel to directions extending substantially laterally of the linear fourth path of travel.
