Patent attributes
A gooseneck hitch adapter has an upper assembly that is designed to affix to an existing trailer. The upper assembly has an upper and a lower torsion tube that each has corresponding torsion bars. The torsion bars extend outwardly where each affixes to a corresponding torsion arm. The hitch adapter has a lower assembly that is designed to affix to a towing vehicle. The lower assembly has an upper and a lower torsion tube that each has corresponding torsion bars. The upper torsion arm affixes the upper torsion bar of the upper assembly to the upper torsion bar of the lower assembly. Correspondingly, a lower torsion arm affixes the lower torsion bars of the upper assembly to the lower assembly. The torsion tubes and bars resist rotation and cooperate to allow limited movement and provide resistance to forces along the axes of the upper and lower assemblies.
