US Patent 7195269 Hitch

A hitch includes a hitch engagement, a hitch tongue and a connecting bridge portion which are forged or otherwise formed as a single, integral, monolithic metal structure. The hitch engagement includes a recess exposed on its bottom side which significantly reduces the weight and material cost of the hitch. The hitch includes generally uniform wall thicknesses with the exception of stress pyramids of greater thickness disposed on the side walls of the bridge portion. A front wall to the hitch engagement is provided which slopes relative to the longitudinal axis of the hitch and connects the side walls bounding the recess. An anti-vibration device can be used within the recess to prevent the hitch from rattling in the hitch receiver.
