ABSTRACT:
A panic exit device has an improved linkage between the push bar and the push bar housing so that no significant horizontal or sideways movement of the push bar occurs as it is pushed inward to unlatch the door. Each linkage employs a link having one linear and one curved slot to smoothly guide the push bar whenever the push bar is pressed inwardly. The device further features a fail-safe dogging mechanism so that the push bar cannot be unintentionally dogged. A fail-safe clip is moved out of an interfering position with the dogging element only when the push bar is moved to unlatch the door.
