Abstract

Abstract An apparatus for facilitating the alignment of a trailer hitch socket with the ball mounted on the towing vehicle is provided wherein a couple of interfitting masts are used. The first mast mounts atop the socket on the trailer tongue and extends vertically upward high enough to the point which it is visible from the towing vehicle. The second mast has a collar to engage it on the ball of the trailer hitch attached to the towing vehicle. It also extends upwardly to a height at which it is visible from within the towing vehicle. As the vehicle backs up toward the trailer, the driver can see the two masts and steer such that they will come closer and closer together and finally nest together when the socket is directly over the ball.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 242 words
A trailer hitch alignment apparatus for aligning a ball of a towing vehicle with a socket defined in a tongue of a trailer, comprising: (a) a first mast comprising a single pipe having an upper portion and a cylindrical lower portion, said lower portion including a top end and a bottom end, said upper portion being defined by a forwardly opening semi-cylinder formed by a longitudinally cut portion of the pipe; the top end of said lower portion defining a shoulder, the bottom end of said cylindrical lower portion removably mounted on the top surface of the socket defined in the tongue of the trailer, said socket having an open bottom face; (b) means for mounting said first mast substantially vertically extended above said socket, comprising an elastic band and an "H" shaped socket spanner plate minus for lying across the open bottom face of said socket, said elastic band being engaged around the shoulder of said first mast and down around the tongue of said trailer and around said "H" shaped socket spanner plate; and (c) a second mast having a collar for slipping on and engaging said ball, said ball having a front end and said mast extending upwardly along side the front end of said ball and having a rear-jogging gooseneck which jogs rearwardly to directly above the ball at which point said second mast continues upwardly from just above the height of the shoulder of said first mast.
