  • Patent number: 4156972
    Abstract: A hitch alignment device includes two components, one component attached to a first engageable member of a hitch mounted to a car and the second component attached to a second engageable member of the hitch mounted to a trailer. Each component has a rod with a reflector plate removably and adjustably clipped near one end thereof. A base plate is removably clipped near the other end of each rod. Each plate abuts a respective engageable member of the hitch. Each rod has a lock washer attached to one end of a stretchable strap. The stretchable strap has a looped outer end. The strap wraps about the respective engageable member with the looped end thereof positioned at the base plate end of the rod so that the rod extends through the loop to retain the strap in the stretched position. The tension of the strap retains the rod in a fixed position to the engageable member of the hitch. The base plate stabilizes the rod against the engeable member.
