DETAILED DESCRIPTION OF THE INVENTION

[0024] Reference is now made to FIG. 1 showing a receiver assembly 10. The receiver assembly 10 includes a central frame member or cross member 12 preferably formed from a pair of tubular steel sections 14 welded to the opposing side walls 16 of a centrally located receiver box 18 so as to project outwardly in opposing directions. The tubular steel sections 14 may be formed with a round cross section as shown in the drawing figures, a square, elliptical, hexagonal or octagonal cross section or any other appropriate shape providing the necessary strength to function as a trailer hitch assembly.

[0025] The receiver box 18 includes a reinforced lip 20 defining an opening leading to a hitch bar receiving cavity 22. Aligned apertures 24 in the opposing side walls 16 of the receiver box 18 allow the secure connection of a hitch bar in the receiver box in a manner well known in the art by means of a connecting pin and cooperating pin clip (not shown). A chain plate 26 is welded to the receiver box 18 and tubular steel sections 14 in order to strengthen the connection. As is known in the art, chain plate 26 includes two apertures 28. The safety chains of a trailer may be connected to the chain plate 26 through engagement in these apertures 28.

[0026] Vehicle mounting brackets 30 are mounted adjacent the distal end of each tubular section 14. More specifically, the brackets 30 are welded to the tubular sections 14 in order to complete the connection. The mounting brackets 30 each include a mounting flange 34 with apertures 38. Nut and bolt fasteners (not shown) are extended through these apertures 38 and cooperating apertures drilled in the frame of the towing vehicle in order to mount the receiver assembly 10 thereto.

[0027] As also shown in FIG. 1, the receiver assembly 10 incorporates a pair of accessory receivers 40 carried on the tubular sections 14 of the central frame member 12. Each of the accessory receivers 40 is formed from a steel tube that is welded to an accessory receiver mounting bracket 42 that is, in turn, welded to one of the tubular sections 14 so that one accessory receiver is positioned between the receiver box 18 and each mounting bracket 30.

[0028] As shown, each accessory receiver 40 includes a circular port or opening 44 and cooperating aligned apertures 46 in the sidewall thereof to allow secure connection of a selected accessory, such as the vehicle body guard or brush bar 50 shown, by means of a connecting pin and pin clip of a type well known in the art (not shown) such as utilized to secure the hitch bar in the receiver box 18. Accessory receiver 40 shown in the drawing as a round cross section may also be square, rectangle or any appropriate shape providing the necessary strength and function.

[0029] In use, each of the accessory receivers 40 is oriented with respect to the central frame member 12, receiver box 18 and the towing vehicle upon which the assembly 10 is mounted so as to be readily accessible by the towing vehicle operator. More specifically, the hitch receiver box 18 extends in a substantially horizontal plane and each accessory receiver 40 has a longitudinal axis extending in a second plane projecting upwardly from the plane of the receiver box 18 and frame member 12 at an included angle of about 10° to about 30° and more typically 20°.

[0030] The manner in which the structural arrangement of the accessory receivers 40 benefits the user when attempting to attach a recreational and/or utilitarian accessory will now be more completely explained. When the receiver assembly 10 is mounted to the towing vehicle, the sections 14 of the central frame member 12 are positioned directly under the bumper of the vehicle. Both the receiver box 18 and the accessory receivers 40 project from the sections 14 so as to extend to or beyond the rear edge of the bumper. Additionally, the accessory receivers 40 project upwardly at an angle of about 10° to about 30° (e.g., about 20°) with respect to the receiver box 18, the frame member 12 and the horizontal. Thus, the circular ports or openings 44 of the accessory receivers 40 are both readily visible and accessible.

[0031] Due to this fact, it is relatively easy for the user to engage the ports or openings 44 of the accessory receivers 40 with the mounting ends 52 of the vehicle body guard or brush bar 50. At this point, the lower lip of the accessory receivers 40 function to support the weight of the accessory 50 as the accessory is being inserted, thereby providing more convenient ease of manipulation. Additionally, the circular shape of the accessory ports or openings 44 and cooperating mounting ends 52 further insure ease of connection. Specifically, since the ends 52 and the openings 44 in the receivers 40 are both round, they present continuous, uninterrupted mating sidewalls. Accordingly, it is not necessary to index the mounting ends 52 in any way to insure proper geometry for mating; simple alignment is all that is necessary. Additionally, the mounting ends 52 may be flexed slightly in virtually any direction during mating as an additional aid when making the connection.

[0032] Once properly aligned, the mounting ends 52 slide readily into the receivers 40. When fully seated, cross apertures (not shown) in the ends 52 are in alignment with the apertures 44. A connecting pin (not shown) is then positioned in these apertures and a pin clip (not shown) is used to secure the pin in position. The resulting two point connection through the receivers 40 dramatically increases the stability of the connection between the vehicle body guard or brush bar 50 and the vehicle. Of course, the vehicle body guard/brush bar 50 may be easily removed by removing the pin clips and connecting pins and pulling the ends 52 from the receivers 40.

[0033] Reference is now made to FIGS. 2a and 2b which illustrate in detail the accessory receiver mounting bracket 42. The mounting bracket 42 comprises a mounting plate having a first slot 60 for receiving the accessory receiver 40 and a second slot 62 for receiving a tubular section 14 of the central frame member 12. Thus, where the receiver 40 is circular in cross section, the first slot 60 is rectangular in shape and where the tubular section 14 of the central frame member 12 is circular in cross section, the second slot 62 is semicircular in shape. Of course, the slots 60, 62 are shaped to correspond to the shape of the receiver 40 and tubular section 14 of the central frame member 12, respectively, no matter what shape they assume. Weld beads illustrated at W complete the connection of the receiver 40, the mounting bracket 42 and the tubular section 14.

[0034] In order to provide the desired upward orientation and projection of the receivers 40 on the central frame member 12, the slots 60, 62 are provided in a particular orientation best illustrated in FIG. 2b. As illustrated, the first slot 60 includes a first axis of symmetry. The second slot 62 includes a second axis of symmetry. Lines A and B extending along these axes of symmetry define an included angle G of between about 20° to about 60° and more typically about 45° to about 50°.

[0035] An alternative embodiment that may be substituted in place of the mounting bracket 42 shown in FIGS. 1, 2a and 2b is illustrated in FIGS. 3a and 3b. This mounting bracket 42′ comprises a pair of cooperating mounting plates 70. Each of the mounting plates 70 includes an aperture 72 for receiving and engaging the accessory receiver 40.

[0036] As illustrated in FIGS. 3a and 3b, the tubular section 14 of the central frame member 12 has an outer dimension D. The pair of cooperating plates 70 are spaced apart a distance D corresponding to the outer dimension D of the tubular section 14. In this manner the pair of cooperating plates 70 engage opposing points 74 on the tubular section 14 of the central frame member 12. Where the plates 70 are formed from steel like the accessory receiver 40 and the tubular section 14, weld beads W may be utilized to complete the connection of these component parts.

[0037] Yet another embodiment of the accessory receiver mounting bracket 42″ is shown in FIGS. 4a and 4b. The mounting bracket 42″ of this embodiment is a pair of cooperating mounting plates 80. Each of the mounting plates 80 includes a first slot 82 for receiving and engaging the tubular section 14 of the central frame member 12. Where that tubular section is circular the configuration of the slot 82 is semicircular or circular. Of course, it should be appreciated that the slot 82 is configured to match at least a portion of the peripheral outline of the tubular section 14 regardless of its configuration or shape (e.g., square, rectangular, hexagonal, elliptical).

[0038] In the illustrated embodiment the accessory receiver 40 has an outer dimension D1. The pair of cooperating plates 80 are spaced apart a distance D1 corresponding to the outer dimension D1 of the accessory receiver 40. Thus, the cooperating plates 80 engage opposing points 84 on the accessory receiver 40. Where the plates 80 are constructed from steel, weld beads W may be provided to complete the secure connection between the accessory receiver 40, the mounting bracket 42″ and the tubular section 14 of the central frame member 12.

[0039] The foregoing description of three possible embodiments of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings.

[0040] For example, embodiments may be provided without the hitch receiver box. As illustrated in FIG. 5, such an embodiment may include a single piece central frame member or cross bar 90 if desired. While not useful for towing a trailer such embodiments allow one to transport and utilize various accessories in a convenient and efficient manner. Further, such an assembly is suitable for use on smaller, relatively low power vehicles that are not suited for trailer towing but are capable of accommodating and transporting a desired accessory.

[0041] In accordance with still another possible embodiment, as shown in FIG. 6, the accessory mounting bracket 42′″ may only include a slot 62 for engaging the outer wall of the central frame member 12. In this configuration, the wall of the receiver 40 includes a pair of slots 63 for receiving the body of the bracket 42′″. Where all component parts 42′″, 40 are steel, the connection may be completed by welding.

[0042] The embodiments were chosen and described to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
