Patent attributes
A coupler lock device is used with a trailer coupler that has a handwheel mounted on a threaded member for securing a hitch ball in the coupler socket. The coupler lock device has a housing configured for covering the coupler socket and the handwheel. The housing includes an opening to allow the housing to be positioned over the coupler socket and handwheel. A closure panel is movable between an open position and a closed position. The housing includes an aperture configured so that when the housing covers the coupler with the handwheel tightened to properly secure the hitch ball within the coupler socket, the handwheel threaded member protrudes through the top aperture and provides a confirmation that the hitch ball is properly, secured for towing.
