ABSTRACT:
A door latch (24) suitable for latching a door (20) to a door frame (22). The door latch (24), in a preferred embodiment, has an adjustable nose bolt (36); is "panic unlatchable"; and can be operated by axial or rotational spindle forces supplied by, for example, a push button (48) or a door knob (120). The latch apparatus (24) preferably includes an adjustable nose bolt (36) which is adjustable in and out relative to the spindle (50). A trunnion (58) interposed between the inside handle (46) and the nose bolt (36) allows for relative adjustment of the nose bolt (36) with respect to the handle (46). In addition, a preferred embodiment of the latch apparatus (24) includes a lock lever (100) which forms a recess (108) suitable for capturing a spindle ear (110) to substantially prevent the spindle from operating the latch apparatus (24) to move the nose bolt (36) from a first position to a second position. Finally, a preferred latch apparatus (24) includes a spindle cam (78) which acts on inclined arms (82) of the handle (46).
