<p>A panic exit actuator and locking mechanism adapted particularly for mounting on a narrow stile door frame with the actuator spanning substantially the full door width and extending between the inner and outer narrow stile frame members, and wherein the lock mechanism is mounted in the outer narrow stile frame member and has a latch bolt supported for movement between latched and unlatched positions, the latch bolt being releasably retained in the latched position by deadlock means and being movable to an unlatched position in response to pressure applied in a door opening direction to a push bar that is movably supported on one or more linkage assemblies having an operating connection with actuating means operable to initially release the deadlock and thereafter move the latch bolt to the unlatched position. The latch bolt in latched position is arranged to engage a strike formed with a camming surface such that, with the deadlock released, the application of opening pressure against the door will cause the camming surface to effect movement of the latch bolt to its unlatched position.</p> |
