A non-handed panic bar mechanism for left or right handed fixing to an exit door having a frame with a stile, upper and lower lock rods 36, 46 for vertically sliding in the stile, and a lock rod drive mechanism, fig 4a (not shown), with a drive pin, 128 projecting outward from the stile for up and down movement, with movement of the pin driving the upper and lower lock rods in opposite directions. The mechanism further includes a base for mounting on an exit door, a pressure bar, 11 carried on the base by a compression mechanism, (76) for movement toward and away from the base, a push rod (71) carried on the base for motion along the axis of the rod, a lever pivotally mounted on the base and having a slot for receiving the drive pin externally of the stile, and a link connected between the push rod and the lever for pivoting the lever to move the lock rods when the pressure bar is pressed toward the base to translate the push rod along it's axis. In alternative embodiments the pressure bar may move a pivoting latch bolt 121, fig 13(not shown) which engages a strike plate on a door frame. A dogging mechanism, Figs 8 - 10, 14, may lock the pressure bar in its compressed condition. <IMAGE> |
