ABSTRACT:
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.
