Abstract
A dogging device for a door panic exit device which provides a tongue portion which releasably engages a ledge portion of an inwardly projecting push bar to lock the push bar in an inward position with respect to the door. The tongue portion is mounted for axial movement and limited rotational movement with respect to a housing of the panic exit device. In an undogged condition the ledge portion moves inward with the push bar and abuts and deflects the tongue portion harmlessly inwardly without any engagement. By axially translating the tongue portion into the housing the tongue portion clears the ledge portion and springs into a position outwardly of a trailing side of the ledge portion whereupon release of the actuating button translates, by a spring bias, the tongue portion back axially toward its original position, which results in the tongue portion being positioned abutting the trailing side of the ledge. A lug abutting the housing limits the rotational movement of the tongue portion so that retraction of the ledge portion, and thus the push bar, is prohibited.
