ABSTRACT:
A panic bar mechanism for an exit door having a frame with a stile, upper and lower lock rods vertically sliding in the stile, and a panic bar carried on levers pivotally mounted on the door frame. The mechanism includes a plate mounted in the stile for rotation about a horizontal axis, upper and lower connectors each having a first end attached to the plate on opposing sides of the horizontal axis and each having a second end attached to the upper and lower lock rods, respectively, and a drive pin carried in the lower connector parallel to the horizontal axis, with one or more of the levers having an inner end directly engaging the drive pin for moving the drive pin upward and rotating the plate about the horizontal axis and moving the lock rods vertically. In the preferred embodiment, the mechanism is non-handed, with both levers capable of engaging the drive pin.
