ABSTRACT:
A panic device that can be easily installed and used with standard doors and door jambs manufactured or prepared for conventional latching mechanisms is disclosed. The disclosed panic device can be used to replace a door knob without replacing or significantly altering the door or door frame. The latching mechanism of the panic device is housed in the hollow sections of a standard door and door jamb, e.g., in sections formerly occupied by a knob and its associated latching mechanism. The panic device includes a panic bar apparatus mounted on the exterior of the door and a latch compressing mechanism occupying the hollow section of the door. The panic bar apparatus and latch compressing mechanism interact with one another to control the movement of a latch bolt inside the door, i.e., the same latch bolt as that employed in the conventional two-knob arrangement. The latch compressing mechanism may also be controlled by a standard door knob or handle mounted on the side of the door opposite the panic bar.
