A door lock assembly includes a housing-carried set of interactive operating components for mounting on a closure for releasingly engaging a keeper that is carried by structure located adjacent to an opening through which access is controlled by positioning the closure selectively in 'open' and 'closed' positions. The lock assembly is 'slam-capable' in that its operating components include a pair of oppositely pivoted, spring-biased latch members that are movable into latching engagement with the keeper as the closure is 'closed'. The lock assembly has a two-part housing formed from first and second members that extend in congruent overlying relationship to define a first passage for receiving portions of the keeper as the closure is 'closed.' Second and third passages open through opposed side walls of the first passage to permit the opposed latch members to move into gripping engagement with portions of the keeper that are received within the first passage. A central chamber is defined between interior surfaces of the first and second housing members for positioning and movably mounting the operating components, including portions of the oppositely pivoted latch members and a selected one of a plurality of slide embodiments that utilize stamped metal components. The slide engages the latch members and engages at least one operating member for effecting 'unlatching' movement of the latch members in response to operation of an operating member. The novel and improved members from which the housing is formed include a first, relatively thick die cast member that matingly engages a second, relatively thin member formed from stamped metal.

Door lock assembly

Flush mountable latches and locks for industrial cabinets, tool carts, electrical equipment enclosures and the like utilize versatile housings of novel configuration together with push-to-operate handles that are pivotally movable relative to the housings to effect unlatching movements of spring-biased, pivotally mounted latch bolts. The lock-type embodiment has a locking mechanism that is mounted on the housing to selectively permit and prevent unlatching movements of its pivotal latch bolt. The resulting arrangement provides sturdy latch and lock assemblies that employ a small number of relatively movable parts that can be assembled, installed and serviced with ease. Improved features include the provision of a plural part handle assembly having portions that are configured to cooperate with a resilient, weather resistant boot that optionally may be interposed between housing and handle assembly components. Other improvements features include the provision of mounting hardware that readily adapts latch and lock units for mounting on structures of a wide variety of thicknesses, and simplifications that enhance the ease of assembly and improve the operation of components that are employed in the lock-type embodiment.

Flush mountable latches and locks for industrial cabinets, tool carts, electrical equipment enclosures and the like utilize versatile housings of novel configuration together with push-to-operate handles that are pivotally movable relative to the housings to effect unlatching movements of spring-biased, pivotally mounted latch bolts. The lock-type embodiment has a locking mechanism that is mounted on the housing to selectively permit and prevent unlatching movements of its pivotal latch bolt. The resulting arrangement provides sturdy latch and lock assemblies that employ a small number of relatively movable parts that can be assembled, installed and serviced with ease.

Flush mountable pulls, latches and locks for industrial cabinets, tool carts, electrical equipment enclosures and the like utilize a versatile housing together with other components of novel form mounted on the housing to provide a variety of desired features. Pull handles as well as latch and lock operating handles of a wide variety of types can be connected to the housing, as can a wide variety of latch bolt mechanisms that are configured to engage various types of strikers or keeper formations. The resulting arrangement provides sturdy pull, latch and lock assemblies that employ a small number of parts that can be assembled, installed and serviced with ease.

Latch and lock housings, handles and mounting brackets

Flush mountable latches and locks for industrial cabinets, tool carts, electrical equipment enclosures and the like utilize versatile housings of novel configuration together with a variety of types of handles that are movable relative to the housing to effect unlatching movements of spring-projected slide bolts. Locking mechanisms are mountable on the housings to selectively permit and prevent unlatching movements of the latch bolts. The resulting arrangement provides sturdy latch and lock assemblies that employs a small number of relatively movable parts that can be assembled and serviced with ease.

Latch and lock assemblies with spring-biased slide bolts

Flush mountable latches and locks for industrial cabinets, tool carts, electrical equipment enclosures and the like utilize versatile housings of novel configuration together with pivotally nestable and extensible handles that are movable relative to their housings to effect latching and unlatching movements of a resilient, expansible latch member. Locking mechanisms are mountable on the housings to selectively permit and prevent unlatching movements of the latch member. The resulting arrangement provides sturdy latch and lock assemblies that employ a small number of relatively movable parts that can be assembled and serviced with ease.

Latch and lock assemblies with expansible latch elements

A rotary handle operated lock includes a pan-shaped housing member that has a back wall at the base of a forwardly facing recess. A guide member is welded to the rear face of the back wall and cooperates with the back wall to define a sturdy guide channel which slidably mounts a control member form movement between locked and unlocked positions. A shaft extends through aligned holes that are formed in the back wall and in the guide member, and through a keyhole shaped slot that is formed in the control member. The shaft has a front end region that carries a pivotally mounted, nestable operating handle, and a rear end region that carries a latching arm. The operating handle and the latching arm rotate with the shaft between latched and unlatched positions. The shaft has opposed flat side surfaces that are selectively engaged and released by the opposed flat sides of the keyhole shaped slot when the control member is moved to its locked and unlocked positions, respectively, whereby the shaft is prevented from rotating or permitted to rotate.
