A door lock includes a plurality of latch bolt assemblies that are mountable on a door at spaced locations about the periphery of the door, an operating mechanism that is flush-mountable on the door at a central location, and elongate linkage elements for interconnecting the operating mechanism with the latch bolt assemblies to enable the operating mechanism to concurrently operate the latch bolt assemblies. The operating mechanism includes a pan-shaped housing, a paddle handle that is mounted on the housing for pivotal movement between a nested position and an extended position, a slide that is track-mounted for sliding movement relative to the housing between first and second positions, a pair of operating arms that are and are pivotally connected to the housing for movement between latched and unlatched positions in response to movement of the slide, and a detent that is interposed between the housing and the slide for assisting to releasably retain the slide in its first and second positions, and to releasably retain the arms in their latched and unlatched positions.
