Abstract: This invention discloses a simple system of components that can be retrofitted to all standard receiver type hitches. It implements the very common round collet wedging principle to the square receiver tube using wedge shaped components to fill the gap between the receiver tube and the draw bar. The wedging action can be applied thru various combinations of differing components shapes. This invention does not modify the existing receiver or ball mount. The system can be adjusted to accommodate for changes after initial installation and previous wear. The wedging action provides forces to center the draw bar inside the receiver tube as well as lock it in place, resisting up/down, left/right, fore/aft movements. There are two basic configurations based on the method of attachment to the existing receiver. The wedge positioning action is the same for both.

Abstract: The subject invention, a collet receiver hitch, has a receiver tube with collet features, and a collet collar to eliminate the problem movement of the draw bar/mount inside the receiver. The first part is a collet receiver tube with an open end for accepting the ball mount shank. The second part is an outside collet collar. The outside collet collar is drawn onto the collet receiver tube, thereby causing the wedging action that, in turn, centers and holds the mount shank. The hitch pin is still required, and its use does not impair the subject invention.
