Background of the Invention
1. Field of the Invention
The present invention relates to a hitch covering device and more particularly pertains to covering and protecting a pin box and kingpin of a trailer hitch with a hitch covering device.
2. Description of the Prior Art
The use of fifth wheel covers is known in the prior art. More specifically, fifth wheel covers heretofore devised and utilized for the purpose of covering a tractor bearing plate are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 5,165,713 to Picard discloses a fifth wheel cover. U.S. Pat. No. 5,058,914 to Murcheson discloses a fifth wheel slip cover. U.S. Pat. No. 4,852,902 to Young et al. discloses a towing hitch cover. U.S. Pat. No. 3,936,077 to Bliek discloses a tonneau cover for fifth wheel camper trucks. U.S. Pat. No. 4,955,968 to Beckerer, Jr. discloses a protective cover for a trailer hitch. U.S. Pat. No. 4,285,138 to Berry discloses a trailer hitch visual alignment device.
While these devices fulfill their respective, particular objective and requirements, the aforementioned patents do not describe a hitch covering device for covering and protecting a pin box and kingpin of a trailer hitch.
In this respect, the hitch covering device according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of covering and protecting a pin box and kingpin of a trailer hitch.

Description of the Preferred Embodiment
With reference now to the drawings, and in particular, to FIGS. 1 through 4 thereof, the preferred embodiment of the new and improved hitch covering device embodying the principles and concepts of the present invention and generally designated by the reference number 10 will be described.
Specifically, it will be noted in the various Figures that the device relates to a hitch covering device for covering and protecting a pin box and kingpin of a trailer hitch. In its broadest context, the device consists of an enclosure and an extension member. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.
The enclosure 12 is dimensioned for slidable coupling over a pin box 14 of a trailer hitch 16. The enclosure 12 has a generally rectangular configuration. The enclosure 12 has an open top 18, a bottom 20, an open forward end 22, a closed rearward end 24 and a pair of long side walls 26. The bottom 20 has an opening 28 extending from the open forward end 22 to a position closer to the closed rearward end 24 than the open forward end 22. The enclosure 12 further includes a rim member 30 having a generally U-shaped configuration. The rim member 30 is coupled with upper edges of the closer rearward end 24 and the pair of long side walls 26. The rim member 30 has a width of about 20% of a width of the bottom 20. The enclosure 12 able to slide over the pin box 14 which is planar and has upturned end portions. Note FIGS. 1 and 2. The rim member 30 will rest atop the pin box 14, as in FIG. 1, to couple the enclosure 12 therewith. The opening 28 allows for a king pin 34 to be cleared by the enclosure 12 upon insertion onto the pin box 14. The closed rearward end 24 will preclude the enclosure 12 from sliding too far with respect to the pin box 14.
The extension member 32 is coupled with respect to the enclosure 12 for coupling over the king pin 34 of the trailer hitch 16. The extension member 32 has a generally square configuration. The extension member 32 has an open top 36, a closed bottom 38, an open forward end 40, a closed rearward end 42 and a pair of side walls 44. Upper edges of the closed rearward end 42 and the pair of side walls 44 are coupled with the recess 28. The extension member 32 is about 50% of a depth of the recess 28. Once the enclosure 12 is positioned on the pin box 14, the extension member 32 will cover the king pin 34 to preclude contact with the king pin which is usually dirty with grease and a dangerous hard surface when contacted, particularly by children.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modification and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modification and equivalents may be resorted to, falling within the scope of the invention.
