1. An article of manufacture titled retrofittable and interchangeable, hitch tightening receiver assembly for attaching multiple hitches to a tow vehicle comprising:
a hitch receiver adapted to be mounted to a tow vehicle, terminating in a rectangular tube, with two holes located at mid-dimension of the tube walls and configured as one round hole and one non-round hole of a predetermined acceptable geometry, allowing hitch(es) with rectangular outside dimensions nominally equal to the hitch receiver, to be inserted until the holes in the hitch receiver align with the horizontal thru hole of the hitch(es), a hitch pin device with a hilt of predetermined acceptable geometry compatible with the predetermined acceptable hole pattern of the hitch receiver and a threaded shaft nominally the same size as the hole thru the hitch(es) of sufficient length to pass thru the receiver and accommodate a hitch pin nut and pin or locking devicewhereby, hitch receiver and hitch pin device can provide anti-rattle and anti-play functions to virtually all commercially available hitches regardless of if hitch is of solid or hollow construction,whereby also, receiver and hitch pin device concurrently provide the full equivalent strength of the load rated assemblies which utilize common commercially available receivers, hitch pins, and hitches,whereby furthermore, the assembly sequence of hitch into receiver is essentially the same as common practice except for the additional step of tightening the hitch pin nut,whereby finally, the invention of claim 1 and the invention of claim 2 may be utilized to fasten any accessory that utilizes the same interface as a hitch. |
