  • Patent number: 6644680
    Abstract: A trailer hitch alignment apparatus designed to be used with an existing trailer hitch that includes a hollow frame tube mounted transversely on the rear of a towing vehicle. The apparatus includes a first leg member that slides into an end opening on the transversely aligned frame tube attached to the frame on the towing vehicle. Attached to the distal end of the first leg member is a joint bracket with a ratchet mechanism disposed therein. Pivotally attached to the distal end of the joint bracket is a second leg member. The ratchet mechanism is coupled to the second leg member enabling the user to forcibly pivot the second leg member around the first leg member. Attached inside the rear surface of the first leg member is a cable assembly containing a cable wound onto a spool. Attached to the spool is a locking, tightening mechanism that allows the cable to be forcibly wound and unwound from the spool. Extending from the distal end of the second leg member is a telescopic extension arm.
