  • Adjustable trailer hitch
    Patent number: 8814198
    Abstract: Using the trailer hitch of the present invention eliminates the need for the driver to drive back and forth several times attempting to align the trailer hitch with the socket on the trailer. The trailer hitch includes a fixed tow bar receiver, and a pivoting tow bar, which automatically locks in an extended position with the tow bar receiver, as the vehicle drives away. With other hitches, the driver must drive forward to line the trailer with the hitch, and then back up the tow vehicle to lock the hitch to prevent it from swiveling.
