ABSTRACT:
A hitch adapter serves as a connection between a prime mover and a towed icle and permits the connection to be selectively configured for on-road or off-road travel. The adapter comprises a beam which has an eye at its fore end hooked to the prime mover and which has apertures at the aft end for engagement with the tongue of the towed vehicle. Fixed atop and under the beam are plates apertured to provide multiple arm mount sites on either side of the beam. A jointed arm swings on either side of the beam at selected ones of the mount sites and a brace arm swingably mounts on either side of the beam at other selected mount sites. The jointed arms include fixed length portions hinged to the brace arms and variable length portions hinged to the fixed length portions. The jointed arms also include releasable lock mechanisms for preventing relative movement between their fixed length and variable length portions. The adapter further comprises feet on the jointed beam that swing toward or away from the prime mover in concert with swinging of the brace arms, the-fixed length portions and the variable length portions.
