Abstract
A panic exit door locking mechanism in which a manually operable panic exit actuator device is mountable on the inside face of a hinged door having a tubular narrow stile frame along its swinging edge; top and bottom adjustable bolt mechanisms at the upper and lower ends of the frame are connected by length-adjustable rod structures, concealed in the narrow stile frame, with a pair of gear connected actuating levers that are operable by means of a drive shaft having a slip-joint connection with an actuating shaft of the panic exit device. The top bolt mechanism includes a keeper secured to an exposed wall of a door frame header by screw actuated inner and outer clamping members. A latching member carried by the door is movable into a keeper latching position when the door is closed, and to a keeper non-latching position when the door is opened. The top bolt is utilized to dog the latch in its keeper latching position.
