Abstract: A panic exit door actuator and locking bolt mechanism of the rim type adapted for mounting in a horizontal position extending generally between the hinged edge and swingable edge of an exit door, wherein the locking bolt comprises a rotatable star wheel with a plurality of circumferentially spaced radial arms that are successively movable by rotation of the star wheel in one direction into salient bolted positions in which they are retained against reverse rotation to an unbolted position by a spring biased latch. The plane of rotation of the star wheel is traversed by the path of relative movement of a bar type strike mounted on the associated door frame, during closing movement of the door, whereupon the strike will engage one of the arms and rotate the star wheel to bring a following arm into a latched, bolted position overlying the strike.

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.
