Abstract

Abstract A hitch extension means for use with a trailer having a forwardly extending tongue means with a first coupling socket means on the forward end thereof. The extension means comprises a second coupling socket means at the forward end thereof which may be detachably secured to a coupling ball at the rearward end of the vehicle. The extension means includes first and second frame members which extend outwardly and rearwardly from the second coupling socket means. A third frame member extends between the rearward ends of the first and second frame members over the tongue means. A plate is secured to the first and second frame members rearwardly of the second coupling socket means and has a coupling ball mounted thereon adapted to detachably receive the first coupling socket thereon. Means is provided on the extension means to limit the movement of the extension means with respect to the trailer tongue.
