Abstract

A overhead door lock which may be used with both manually operated and motor operated doors. The lock has a base adapted to be mounted on the door, and has a mounting plate and a pair of spaced apart legs. Each leg carries a slide aperture, and one leg includes a lockout hole. A striker plate is attached to the door channel in a position collinear with the base. A spring biased striker is carried by the base and when the door is manually operated, the striker is placed in an operative position where it slides freely through generally aligned slide apertures. When the door is motor operated, the striker may be placed in an inoperative lockout position by placing one end of the striker in the lockout hole. When the striker is in the inoperative lockout position, it cannot contact the striker plate when the door is in the closed position. However, the striker may be easily moved to the operative locking position by overcoming the spring bias, and moving the striker into the slide aperture and thus engageable with the striker plate to lock the door in the closed position.
