Detailed Description of the Invention

As shown with reference to Figure 1, the apparatus 10 of the present invention includes a body 12 having an accessory mounting port 14 and a mounting plate 16. Preferably both the accessory port 14 and the mounting plate 16 are formed from steel which is welded together to form a single unitary body 12. As best shown in Figures 2 and 3, the accessory mounting port 14 may be circular in cross section. Alternatively, it should be appreciated that substantially any non-circular cross section may be utilized for the port and mating post. As shown in Figures 1-3, the accessory mounting port 14 may also include opposed apertures 18 in the wall thereof. The accessory that is plugged into the port includes cooperating opposed apertures in the post P so that a connecting pin may be inserted therethrough to secure and lock the accessory in position in a manner known in the art (connecting pin and cooperating locking clip not shown in the drawing figures).

As also shown in Figures 1-3, the mounting plate 16 includes four mounting apertures 20, one at each corner thereof. A fastener in the form of a pair of cooperating U-bolts 24 and four nuts 26 are used to secure the apparatus 10 to the trailer hitch receiver R. More specifically, the mounting plate 16 is butted up against the face F of the hitch receiver cross member C. Where that cross member C includes a bend B at the mounting point as shown in Figure 3, a shim 28 may be provided in order to allow the apparatus 10 to be mounted square with the face F of the hitch receiver R. Mounting brackets Z at the two ends of the cross member C secure the trailer hitch receiver R to the frame of the towing vehicle in a manner well known in the art.

With the body 12 held in the desired mounting position against the face F of the cross member C, the threaded ends 30 of the U-bolts 24 are passed through the mounting apertures 20 so that the cross member C is captured between the U-bolts and the mounting plate 16. The nuts 26 are then tightened to secure the apparatus in the desired position on the trailer hitch receiver R. Of course, locknuts or standard nuts and cooperating lockwashers may be utilized. In an alternative mounting arrangement shown in Figure 4, the front face F of the cross member C may carry a mounting flange M. More specifically, the mounting flange M is preferably formed of steel and is welded to a tubular steel extension arm A which is likewise welded to the face F of the cross member C hidden behind the mounting bracket Z in the drawing figure. In this alternative embodiment, the fastener 22 may comprise bolts 32 and cooperating locknuts 34 rather than the U-bolts 24 of the previously described embodiment. The bolts 32 are passed through the mounting apertures 20 in the mounting plate 16 and cooperating apertures formed in the mounting flange M. The locknuts 34 are then tightened on the bolts 32 to secure the connection.

A second alternative embodiment of the apparatus 10 of the present invention is shown in Figure 5. In this embodiment, the body 12 includes an accessory mounting port 14 of the type previously described incorporating apertures 18 in the sidewall thereof. Rather than the mounting plate 16 shown in Figure 1, however, the apparatus incorporates a U-shaped mounting bracket 36. The U-shaped mounting bracket 36 is formed from steel and the accessory mounting port 14 is welded thereto so as to form a unitary body 12.

As shown in Figure 5, the U-shaped mounting bracket 36 includes a first set or pair of aligned apertures 38 and a second set or pair of aligned apertures 40. The second embodiment of the apparatus 10 is mounted on the cross member C of a hitch receiver R by placing the U-shaped mounting bracket 36 over the cross member so that the upper leg 42 overlies the cross member while the lower leg 44 underlies the cross member and the base 46 abuts the front face F thereof. The fastener comprises a pair of straight bolts 48 with one being extended through the aligned apertures 38 and the other being extended through the aligned apertures 40 behind the cross member C so that the cross member is effectively captured between the bolts, the two legs 42, 44 and the base 46 of the U-shaped mounting bracket 36. Locknuts 50 are utilized to secure the bolts 48 in position. Of course, it should be appreciated that the pair of bolts could be replaced with another form of fastener such as a single U-bolt (not shown) with the threaded ends of the U-bolts extending through the cooperating apertures and being secured in position with the locknuts.

Yet another alternative embodiment is shown in Figure 6. The apparatus 10 of this embodiment includes a body 12 having an accessory mounting port 14 of the type previously described including apertures 18 in the sidewall thereof. The mounting plate 16 is replaced in this embodiment with a substantially V-shaped mounting flange 52. The V-shaped mounting flange 52 includes a pair of opposed lugs 54. Each lug 54 includes a pair of mounting apertures 56.

The apparatus 10 of this embodiment also includes a substantially V- shaped mounting bracket 58. The mounting bracket 58 includes a pair of opposed lugs 60. Each of the opposed lugs 60 includes a pair of mounting apertures 62 which are spaced to be aligned with the apertures 56 in the lugs 54 when the mounting bracket 58 is positioned on the mounting flange 52 as shown.

This embodiment of the apparatus 10 is mounted to the hitch receiver R by placing the vertically extending leg (as shown in the figure) of the V-shaped mounting bracket 52 against the front face F of the cross member C and the horizontally extending leg thereof against the bottom wall of the cross member. Next, the mounting bracket 58 is placed over the cross member so that the horizontal leg (as shown in the figure) thereof overlies the upper wall of the cross member C and the vertical leg thereof overlies the rear wall of the cross member. The lugs 54 of the mounting flange are aligned with the lugs 60 of the mounting bracket 58 so that the apertures 56 in the lugs 54 and the apertures 62 in the lugs 60 are all aligned. A fastener, in the form of four bolts 64 are then used to secure the apparatus 10 in position. Specifically, one bolt is extended through each of the aligned sets of apertures 56, 62 and a cooperating locking nut 66 is utilized to secure the bolts in position with the cross member C captured between the mounting flange 52 and the mounting bracket 58.

As shown in Figure 7, still another alternative embodiment of the apparatus 10 may have a body 12 including a substantially V-shaped mounting flange 70 carrying an underslung accessory mounting port 72. A steel gusset 74 may be provided between the vertically extending leg 76 of the mounting flange and the wall of the accessory mounting port 72. The gusset 74 is welded in this position to provide added strength and rigidity. This embodiment also includes a substantially V-shaped mounting bracket 78 to allow it to be mounted to the hitch receiver R in the same manner as described above with respect to the Figure 6 embodiment using bolts 80 and nuts 82.

Three additional alternative embodiments are shown in Figures 8, 9 and 10. As should be appreciated, the Figure 8 embodiment substantially corresponds to the Figure 1 embodiment except for the fact that the accessory port 14 is replaced with a bar-like body or lug 14' that projects from the mounting plate 16. The Figure 8 embodiment mounts to a hitch receiver R in the same manner of the Figure 1 embodiment as previously described and illustrated in Figures 2-4.

The Figure 9 embodiment substantially corresponds to the Figure 6 embodiment except for the fact that the accessory port 14 is replaced with a bar-like body or lug 14' that projects from the V-shaped mounting bracket 52. The Figure 9 embodiment mounts to a hitch receiver R in the same manner of the Figure 6 embodiment as previously described and illustrated in Figure 7.

The Figure 10 embodiment substantially corresponds to the Figure 5 embodiment except for the fact that the accessory port 14 is replaced with a bar-like body or lug 14' that projects from the base 46 of the U-shaped bracket 36. The Figure 10 embodiment mounts to a hitch receiver R in the same manner of the Figure 5 embodiment as previously described.

It should be appreciated that the bar-like body or lug 14' of each of the Figure 8, 9 and 10 embodiments includes a rounded tip 90 that allows for easy insertion into the cooperating opening of any post P being mounted thereon. Such a post P is typically configured from hollow rectangular tube stock so as to closely fit the post around the bar- like body or lug 14'. It should be appreciated, however, that a post 14 with a round opening such as shown in Figure 2 could also be utilized. Further, each bar-like body or lug 14' may include a locking aperture 92 and/or a locking notch 94 that cooperatively receives a connecting pin or latch to secure the post to that body/lug. As illustrated, the locking notch 94 may be formed in an edge 96 of the body/lug 14' if desired.

Further, in a typical embodiment it should be appreciated that each port 14 and/or bar- like body or lug 14' extends upwardly at an angle to a horizontal plane of between about 1 to about 89 degrees and still more typically between about 5 to about 45 degrees and most typically between about 10 to about 30 degrees (see, for example, Figure 4). As a consequence, the port 14 or lug 14' is more readily visible for ease of post P alignment during installation of an accessory. Additionally, gravity aids in fully seating a post P in/on the port 14 or lug 14'. Such an angle also introduces a moment into the accessory linkage so that forward acceleration of this vehicle does not produce only rearward movement forces on the accessory.

In summary, numerous benefits result from employing the concepts of the present invention. The mounting apparatus 10 of the present invention allows one to mount one or more accessories to the trailer hitch receiver assembly R of a towing vehicle without occupying the receiver box. As such, the receiver box may continue to hold a hitch bar and disconnection of the hitch bar is not necessary to accommodate accessory transport. Additionally, the present invention allows one to retrofit an existing trailer hitch receiver assembly R to carry the new generation of accessories introduced by Reese Products, Inc. and other manufacturers which provide for a multipoint and therefore more stable mounting arrangement. Further, while two ports 14 are illustrated in Figure 2, it should be appreciated that substantially any reasonable number of ports 14 and/or lugs 14' may be secured to a hitch receiver R depending on the particular application and/or desires of the vehicle operator (e.g. from one to perhaps four or more).
