Patent attributes
A device is disclosed for locking to a gooseneck-type trailer tongue of the type having a lockable tongue mechanism and a lower surface. A ball member has a semi-spherical upper portion and a lower surface. The lower surface is traversed by a threaded aperture. A peripheral side of the upper portion has at least one set screw aperture traversing through to the threaded aperture. A tang is threaded at a top end thereof for threaded rotational engagement with the threaded aperture of the ball member and includes a lower end that has at least one bolt aperture therethrough. A collar member includes a tang slot traversing the top and bottom surfaces thereof. A puck lock has a selectively positionable bolt adapted to traverse the bolt aperture of the tang to lock the collar member onto the tang and ball member. The top surface of the collar member is locked against the lower surface of the trailer tongue to prevent removal of the ball member from the trailer tongue, thereby inhibiting unauthorized towing of the trailer.
