Abstract
A push pad exit device comprising a horizontal push bar actuator mechanically linked to a vertical door handle assembly, for use on the interior side of entrance doors where a means of emergency egress is desired, is presented. The operating mechanisms of the push bar actuator and vertical door handle assembly are concealed presenting a smooth uncluttered appearance. In one mode of operation, the push pad actuator may be moved inwards towards the door face causing the door to unlatch. The push pad exit device may also be equipped with a “dogging feature” which locks the push bar actuator in the unlatched position. In this mode of operation the door is unlatched and the push pad actuator may be used as a fixed door handle. The push pad exit device may also be equipped with a keyed lock on an external face of the door.
