ABSTRACT:
A panic device actuator for a door includes apparatus for unlatching a door mounted in a door frame and which includes one or more elements movable for retracting one or more door latches normally engaged with the door frame for positively locking the door. The panic actuator includes a relatively large panel having an enlarged outer face responsive to pressure applied at any area thereon for unlocking the door without a key. A mounting system is provided for supporting the panel on the door for controlled movement in a horizontal direction in continuous parallelism with the face of the door in a direction normal to the door face. A linkage is provided for interconnecting the panel and the door latching element(s) for moving the same to unlock the door latches in response to pressure movement of the panel on the door. The novel panic actuator is designed so that pressure applied at any point on the outer face of the panel results in movement of the panel as a whole in precise parallelism with the door face without wedging or binding and a standard size panel may be used with doors of different widths.
