ABSTRACT:
This invention relates to a novel hitch receiver/implement threaded fastening assembly. More particularly, this invention pertains to a novel device for securing in place an implement such as a tow bar, ball mount, bicycle rack, and the like, in a hitch receiver mounted on a vehicle. The device replaces a conventional draw pin. An insert device for removably securing a tube type shank of an implement to a hitch receiver tube comprising a resilient elongated double “U”-shaped frame which at a first central location bends in a “U”-shape along a first plane, and the pair of arms of the frame at a pair of complementary second locations on the frame, bending in a pair of “U”-shapes in parallel along a second plane perpendicular to the first plane, a first nut secured within one of the arms of the second “U”-shape, and a second nut secured within the other of the arms of the second “U”-shape, the first and second nuts being spaced and aligned in parallel arrangement with one another. A pair of bolts and lock washers are used in combination with the device for securing the implement tube to the hitch receiver. By using the device, and the bolts, the walls of the implement tube and the hitch receiver tube are tightly cinched together and movement therebetween is eliminated.
