ABSTRACT:
A locking apparatus for a garage door which utilizes a pair of actuators with one actuator being mounted at a side edge of the garage door and the other actuator mounted at the opposite side edge of the garage door. One actuator is mounted on a carrier gear which connects to a worm gear which is driven by an electric motor. Each operator connects with a locking bolt with there being a separate locking bolt for each actuator. Each locking bolt is to be movable in conjunction with the door jamb of the garage door to lock the garage door to the jamb. Both actuators pivot in the same direction. Both locking bolts are linearly slidable. A connecting member connects between the first actuator and the second actuator so that the actuators move in unison. One actuator has a back end which extends through a slot formed in a latch housing. This back end is manually accessible to cause the actuator to move manually if electricity fails.
