Abstract
A keyless locking system includes a housing in a generally rectilinear configuration having a plate with peripheral edge walls to form an open housing there between. A rotatable assembly is secured to the front wall and includes a visible rotator extending inwardly from the front wall and a cylindrical shaft extending through the front wall. A C-shaped channel member extending interiorly from the front wall to encompass and contact the sides of the deadbolt. A gearing assembly includes a large gear coupled to the channel member and a smaller gear and an intermediate gear whereby rotation of the intermediate gear will rotate the smaller gear and then the larger gear to rotate the channel member and deadbolt to lock and unlock the door. A motor within the housing with an associated battery drives the intermediate gear. An electronic assembly effects the driving of the motor and intermediate gear in a first direction and then a second direction. A control member, adapted to be held by the hand of the user, includes an actuator adapted to be moved to drive the motor a predetermined number of revolutions to rotate the intermediate gear, small gear, large gear, channel member and deadbolt for either locking or unlocking the door. An adhesive is secured to the housing interiorly of the edge walls to secure the housing onto a door with the channel member over the deadbolt of the door.
