Patent ID: 7240524

Claim:
A locking apparatus for a garage door adapted to be locked to a door jamb comprising: a first actuator designed to be pivotally mounted on the garage door directly adjacent a first side edge of the garage door, said first actuator being mounted on a carrier gear, a worm gear connecting with said carrier gear, an electric motor to cause rotation of said worm gear and hence pivoting of said carrier gear and said first actuator, said first actuator mounted on a latch housing; a second actuator designed to be pivotally mounted on the garage door directly adjacent a second side edge of the garage door; a connecting member connected to both said first actuator and said second actuator so both said first actuator and said second actuator will move in unison; a first locking bolt connected to said first actuator, movement of said first actuator causes sliding movement of said first locking bolt between a first locking position in conjunction with the door jamb and a first unlocking position spaced from the door jamb; said first locking bolt having a cutout, said cutout having a cutout wall, said first actuator having a rounded front end which has a somewhat flattened configuration, said flattened configuration to abut against said cutout wall when said first locking bolt is in said first locking position producing an “over-the-center” position which prevents movement of said first locking bolt by interference being created between said first locking bolt and said first actuator, movement of said first locking bolt is only possible by initiating movement of said first actuator; said first actuator having a back end which extends through a slot formed in said latch housing the first actuator extends exteriorly of said latch housing, said back end being manually accessible to cause said first actuator to pivot to cause said first locking bolt to move; a second locking bolt connected to said second actuator, movement of said second actuator causes sliding movement of said second locking bolt between a second locking position in conjunction with the door jamb and a second unlocking position spaced from the door jamb; and whereby with said first locking bolt in said first locking position and said second locking bolt in said second locking position the garage door is fixed to the door jamb, whereby with said first locking bolt in said first unlocking position and second locking bolt in said second unlocking position the garage door is movable relative to the door jamb.
