Locking device for a two-door unit of swinging type

Abstract

An improved locking device is provided for use on a pair of panic doors. The locking device includes an actuating bolt including a triangularly-shaped body and being formed with a stopper portion and a recessed portion; a curved pivotabie member which is formed with a pair of opposite guide pegs slidably abutting on the stopper portion on the actuating bolt and is pivotably turnable when the actuating bolt is being pushed inwards; a movable tube which is axially movabvle when the curved pivotable member is being pivotally turned; a slidable bar which is slidable with the axial movement of the movable tube; and a latching bolt linked to the slidable bar so that when the slidable bar is moved the latching bolt is protruded out of the locking device to lock the paired panic doors. It is a chacteristic feature of this locking device that the exerting force can be applied at various angles to the actuating bolt, while nevertheless allowing the actuating bolt be smoothly pushed inwards to actuate the latching bolt to lock the paired panic door.
