Description
ANTI-WOBBLE DEVICE FOR RECEIVER-TYPE TRAILER HItCH
FIELD OF THE INVENTION
The invention relates to receiver type trailer hitches, and more specifically to a s device for eliminating rattling due to movement of connecting parts in the hitch.
BACKGROUND OF THE INVENTION
In receiver-type hitches, in order to avoid seizing of the mount inside the receiver tube, the mount and receiver tube ace adapted to engage each other loosely-the receiver tube is made wider or the mount is made nan~ower. Due to the io receiver tube receiving the mount non-frictionly, there will consequently result a wobbling movement between the mount and the receiver tube causing vibrations and rattling noises.
Various devices and methods have been invented to deal with this problem.
Known prior art includes U.S. Pat. No. 6,382,656 issued May 7, 2002, to is Johnson, Jr.; U.S. Pat. No. 6,105,989 issued August 22, 2000, to Linger;

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
s The following description shows only preferred embodiments of the present invention. Various modifications are apparent to those skilled in the art without departing from the scope of the present invention, which is only limited by the appended claims. Therefore, the embodiments shown and described are only illustrative, not restrictive.
io Also, throughout the following description, specific details are set forth in order to provide a more thorough understanding of the invention; the invention, however, may be practiced without these particulars. In other instances, well-known elements have not been shown or described in detail to avoid unnecessarily obscuring of the invention.
is Referring to Figure 1, there is illustrated in a perspective view, an anti-wobble receiver-type trailer hitch device (generally indicated by reference numeral 100) in accordance with the preferred embodiment of the present invention. The hitch device includes a receiver tube 102, which is usually attached to the towing vehicle, and a mount 101. The mount 101 telescopes with (and, specifically, 2o inserts into) the receiver tube 102, which is hollow.
When the mount 101 is fully telescoped to the receiver tube 102, a conventional cross pin (not shown) is inserted through the holes 106, 105 to hold the components 102 and 101 together. The mount 101 may have a cut-off comer 108 to facilitate its insertion into the receiver tube 102.
3 To prevent the seizing of the mount 101 inside the receiver tube 102, the components (101, 102) are adapted to telescope loosely, resulting in the wobbling of the mount 101 inside the receiver tube 102. In the present invention, to inhibit such wobbling, the bottom wall of the receiver tube 102 comprises an s elongated embosser (tongue) 104 along its longitudinal axis, while the bottom wall of the mount 101 comprises an elongated groove (channel) 103 along its longitudinal axis. The embosser 104 and groove 103 are adapted so that when the mount 101 is inserted into the receiver tube 102, the embosser 104 snugly receives groove 103 locking the mount 101 against wobbling movement inside io the receiver tube 102.
A conventional trailer ball 107 is attached to the other end of the mount 101 the non-inserted end. While the preferred embodiment of the instant invention is described in reference to a ball mount 101, it can be used without adaptation or with modification in conjunction with a variety of adapted mounts-mounts is comprising a channel (or an embosser, as explained below-insertable and removable into and from the receiver tube 102, such as hitch mountable bicycle carriers, ski carriers, utility shelf carriers, truck ramps, truck-bed extensions, and other devices mountable to a receiver tube 102 of a receiver type trailer hitch.
In this document, the embosser 104 and groove 103 were illustrated as being 2o formed along the bottom walls of the receiver tube 102 and mount 101, respectively. This should be regarded as a preference, rather than a restriction.
Also, Figures 1 and 2 show the embosser 104 and groove 103 along the middle of the aforementioned walls. This, too, is not a restriction. Furthermore, the invention would also work by having the embosser formed on the mount, and the 2s groove formed in the receiver tube.
The alternative embodiments discussed in the preceding paragraph are not shown. However, Figure 2 shows yet another embodiment of the present invention. (Like parts have been given the same reference numerals.) In this
