Abstract: A tool-operated latch has a body which is mountable on the back side of a door panel adjacent an elongate opening and a hole formed through the door panel. An elongate latch lever is pivotally carried by the body and is movable between a latched position wherein the latch lever is nested with respect to the elongate door opening, and an unlatched position wherein the latch lever is extended with respect to the elongate door opening. A tool-operable actuator is journaled by the door panel hole and by the latch body, and is movable by a specially configured tool between locked and unlocked positions. A pawl is pivotally carried by the body for movement between a retaining position wherein it engages the latch lever to releasably retain the latch lever in its nested, latched position, and a releasing position wherein the pawl releases the latch lever thereby permitting the latch lever to be moved to its unlatched, extended position.

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.

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 is mounted for translatory movement along one side of the bolt to bring other disconnect components selectively into and out of driving engagement. A key-operated locking member moves the disconnect member between connecting and disconnecting positions. 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.

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.

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 an operating member which is pivotally mounted on the body at a location behind the handle, a key-control which is carried on the handle, and a disconnect member which is carried by the key control for movement into and out of driving engagement with the operating member. The operating member has an arm which extends through an opening formed in the back of the body and into driving engagement with the bolt. A two-piece guard shields the members of the disconnect linkage from access by would-be intruders.

Abstract: A cabinet lock has a one-piece housing with spaced front and back walls interconnected by an end wall and by a pair of spaced side walls. The housing has a first set of aligned holes formed through the front and back walls, and a second set of aligned holes formed through the side walls. A lock actuator mechanism is journaled by the first set of holes and includes an actuator movable between locked and unlocked positions. A rotary latch bolt mechanism is journaled by the second set of holes and includes a latch bolt movable between latched and unlatched positions. The lock actuator mechanism includes a first spring which biases an actuator toward its locked position. The latch bolt mechanism includes a second spring which biases the latch bolt toward its unlatched position. The lock actuator mechanism includes a cam with is interengageable with the latch bolt to retain the latch bolt in its latched position until the lock actuator is moved to its unlocked position.
