Abstract

Abstract An automatic operator for an overhead garage door gravity-biased to a closed position includes a keeper centrally positioned on the garage above the doorway, a pivotally biased latch member secured to the top of the door and spring-biased into a locking configuration wherein it is engageable with the keeper for locking the door in its closed position, a reel mounted in the garage above the top of the door centrally thereof, a cable interconnecting the reel and the latch member, a reversible electric gear head motor coupled to the reel for rotating same in a winding direction to unlock the latch and open the door and in an unwinding direction to permit closing of the door and locking thereof by the latch member, means for actuating the motor, and motor control circuitry including a screw-type limit switch responsive to rotation of the reel for deactuating the motor after opening or closing of the door.
