Abstract
Abstract A lock pin extends through a door frame and into a hole in the edge of a door to provide a hidden positive door lock. The lock pin is retracted by a motor mechanism, either electrically or manually powered, mounted in the trunk of the automobile. The pin may be spring biased toward a lock position, or may be thrust into such position by means of a Bowden cable. The motor may be in the form of a simple lever and Bowden cable arrangement, a hand cranked gear and pulley arrangement, or an electric motor, such as a power window motor.
