ABSTRACT:
A garage door locking device (10) includes a bracket (12) for connection to a garage door (12) and translating initial push/pull movement of a first push/pull cable (20) into locking and unlocking actuation of a latch member (30), respectively. The bracket (32) includes a slot defining a track having closed ends at each end thereof for stopping and engaging a follower member (44) mounted thereon. A second push/pull cable (48) has a first end connected to the follower member (44) and a second end connected to a latch member (30) so that the follower member (44) is biased towards one of the closed ends of the slot (40) when the latch member (30) is engaged to lock the door and the follower member (44) engages the other closed end of the slot (40) when the latch member (30) is disengaged from the locked condition.
