The invention described here may be made, used and licensed by and for the U.S. Government for governmental purposes without paying royalty to me.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to a tow hitch lunette assembly.
2. Background Art
Tow hitch assemblies are generally implemented in connection with a tow vehicle such as a truck and a towed vehicle such as a trailer and the like. Trailers for construction equipment and other heavy-duty trailers often use a hitch assembly
having a lunette eye trailer tongue to provide mechanical coupling between the tow vehicle and the towed vehicle. The lunette tongue can include a rigid, durable, hitch ring or "eye" having a toroidal (i.e., "donut" or lunette) shape. The eye can be
placed over or secured to a vertical post or pin, or latched into a pintle, or the like on the tow vehicle.

For use in a vehicular trailer hitch system, a vehicular trailer hitch
lunette assembly is provided. The assembly includes at least one "U"
shaped outer laminate plate having two legs with a semi-circular region
therebetween, and at least one substantially flat inner laminate plate
positioned between the legs of the U-shape of the outer laminate plate to
provide support, stiffness, and additional mechanical strength to the
assembly. The outer laminate plate and the inner laminate plate have
cooperating apertures that are traversely positioned therethrough and the
apertures are aligned and sized such that fasteners may be snugly
inserted therein to mechanically couple the laminate plates together as a
sandwich structure having first and second ends. The semi-circular region
of the outer laminate plate and ends of the inner laminate plate comprise
an inner void at the first end of the assembly to provide a lunette
shaped st . . . . More |
