摘要： A door locking device comprises a locking bolt movable from a retracted position within the door edge, to a projected position for locking the door within the door frame, and a feeler member engageable with the door frame when the door is in its closed position to automatically actuate the locking bolt to its projected position, and thereby to automatically lock the door in its closed position. The automatic locking of the door may be disabled either by the application of a proper key in the key cylinder, or by the depression of a foot pedal. The described embodiment includes two locking bolts both of substantial vertical length so that together they occupy at least 50% of the door height.
