ABSTRACT:
A self locking device that is used with a overhead, horizontally pivoted, door in combination with a power operated door opener is disclosed. The device comprises a latch mechanism that is activated by the movement of the door arm and a striker that receives a locking dog. A door arm, which is a part of the door opener, is the member that transfers the movement of the power operated door opener to the door. When the door arm is closing the door, the locking dog is free to interface with a striker. A striker mounted on the header of the door frame receives the locking dog and keeps the door from being forced open which can be done by breaking the door opener mechanism. The latching dog is released by the door opener mechanism with the reverse movement of the door arm and therefore the door is moved to its open position.
