Abstract

The slidable hitch of the present invention includes a pedestal having a plurality of wheels mounted for rolling movement on a pair of spaced apart runners, the runners being mounted on the bed of a truck. The pedestal includes a pair of vertical side plates with projecting flanges at the lower end, the flanges journaled between an upper leg and lower back of each runner, to prevent vertical movement of the pedestal off of the runners. Each wheel is substantially enclosed within a pocket to protect the wheels from weather and the environment. A pair of set pins are mounted on each side plate and movable downwardly to engage one of a plurality of holes in the upper leg of the runner, to selectively lock the pedestal in a desired position along the runners. The pedestal includes one of a variety of hitch mechanisms, one embodiment disclosing a hitch ball mounted on a plate on the pedestal, and another embodiment disclosing a fifth wheel hitch plate mounted on the pedestal. A rocker arm assembly is mounted between the side plates of the pedestal with a beam extending transversely between a pair of pivot rods pivotally mounted on the upper end of a pair of stanchions, such that the hitch plate mounted on the beam is pivotable on a transverse axis. The stanchions are vertically adjustably mounted on the side plates to permit raising and lowering of the hitch plate on the pedestal. A housing is pivotally mounted on the beam of the rocker assembly on a pivot axis which is orthogonal to the pivotal axis of the rocker assembly, such that the hitch plate is pivotable on both transverse and longitudinal axes.
