Abstract:
A trailer hitch comprising a draw tongue adapted to extend from a trailer, a handle mounted for pivotal movement above the draw tongue, and a cable attached at one end to the handle and extending downwardly through the draw tongue to a hitch coupler which is carried for bodily movement upwardly and downwardly as a function of pivotal motion of the handle. A drawbar adapted to be attached to a towing vehicle is slotted to receive the hitch coupler and recessed to capture the coupler as the latter is moved upwardly by pivotal movement of the handle. A resilient bushing of elastomeric material is captured in compression between the drawbar and the draw tongue resiliently to permit relative movement in all planes and to damp road shock therebetween.
