ABSTRACT:
A rod casing for activating vertically arranged latch bolts, the casing and latch bolts arranged in an active stile of a door and engageable to a door frame. The rod casing provides a vertically slidable actuator cam engageable by both a lock/unlock actuator and a delatch or dogging actuator. The lock/unlock actuator and the delatch actuator are rotatably mounted upon a spindle piece which itself is rotatable by a user such as by a key-activated lock cylinder. The lock-unlock actuator when rotated, slidingly abuts the actuator cam and drives the actuator cam vertically upward to cause unlatching of the latch bolts. The delatch actuator, upon rotation of the spindle piece in an opposite direction underlies the actuator cam and dogs the actuator cam in its vertically risen position. A panic exit device is also provided which has a lift plate mounted fixedly to the rod slide, the lift plate liftable by a pivoting of a lift lever, the lift lever pivoted by a lateral thrusting of a push plate slidably held beneath a push pad of the panic exit device. When compressed by a user, the push pad compresses two motion actuators housed beneath the push pad which laterally translate the push plate toward the lift lever. A spring loaded panic exit device dogging mechanism is also provided.
