  • U-lock with strength enhancing header extensions
    Patent number: 5467620
    Abstract: A U-lock includes a detachable header with extensions that fit around the arms of the U-bar and extend along the length of those arms to provide strength to the U-lock. The header can be used so that its base is locked at the end of the arms of the U-shaped bar or it can be inverted when locking smaller objects so that its base is locked along the lengths of the arms taking up some of the gap between the locked object and the base of the header. The header is locked to the arms of the U-shaped bar by a locking mechanism which secures the header to the arms of the U-shaped bar in four different places, two on each arm. The U-lock and header with extensions can also be used in combination with security spacers for further security.
