DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings, and particularly to FIGS. 1-10, a preferred embodiment of the grill mounting apparatus for a vehicle of the present invention is shown and generally designated by the reference numeral 10.
In FIG. 1, a new and improved grill mounting apparatus for a vehicle of the present invention for mounting a grill to the bumper of a vehicle is illustrated and will be described. More particularly, the grill mounting apparatus for a vehicle 10 is shown attached to the rearward bumper 12 of a vehicle 14, such as a recreational vehicle (RV). The grill mounting apparatus 10 includes a support platform 16 that is attached to a support arm 18 which is pivotally attached to the bumper 12. The support platform 16 can be pivotally secured to the support arm 18 allowing the support platform to pivot about its attachment point to the support arm. A grill 20 is positioned on the support platform 16 and can be fixedly attached thereto by a least two grill mounting flanges 22 and the grill is secured to each mounting flange through the use of a fastener 24, such as a bolt. The support platform 16, having the grill 20, can be positioned outward from the bumper 12 and the rearward portion of the vehicle 14 by pivoting the support arm 18 about its attachment point to the vehicle bumper, thereby making the grill accessible for cooking. A pivot mount assembly 26, which will be described in further detail subsequent hereto, attaches the support arm 18 to the vehicle bumper.
Ideally, the support platform 16 is generally rectangular in shape and has a length that is greater then the length of a grill 20 to be supported by the platform. Preferably, the grill 20 is positioned to one side of the support platform 16, thereby leaving a portion of the support platform available for workspace.
Turning to FIG. 2, the grill mounting apparatus 10 is shown with the support arm 18 rotated away from the bumper 12 and towards the side of the vehicle 14. The ability for the support platform 16 to pivot about the support arm 18 is illustrated in this view with the support platform being pivoted about the support arm approximately 100 degrees, thereby allowing the grill to remain facing outward from the vehicle 14. The support platform 16 is free to pivot about the support arm 18 a full and continuous 360 degrees.
The grill mounting apparatus 10 further includes a retaining mount assembly 28 that is attached to the bumper 12 at a spaced distance from the pivot mount assembly 26. The retaining mount assembly, which will be described in detail later, is provided to retain the support arm 18 in a non-use, stored position against or parallel to the bumper 12 and prevent the support arm from pivoting about the pivot mount assembly 26.
Turning to FIG. 3, the grill mounting apparatus 10 is shown with out the grill 20 and not attached to the bumper 12 of the vehicle 14 and is illustrated in a preferred embodiment having four grill mounting flanges 22. Two grill mounting flanges 22 are attached to the support platform along one edge thereof with the remaining two grill mounting flanges attached to the support platform intermediate its ends and at an equal spaced distance from the first two flanges. The equal spaced distance between the flanges is substantially equal to the width of the grill 20 being attached to the grill mounting apparatus 10. The flanges 22 each include a hole 30 formed therethrough for passing a fastener 24 through to secure the grill 20 to each flange.
Referring now to FIGS. 4-10, the grill mounting apparatus 10 includes a support arm 18, a support platform 16, a pivot mount assembly 26 and a retaining mount assembly 28. The support arm 18 of a diameter is generally oriented parallel with the horizon and includes a first end 30, a second end 32 and a horizontal portion 34 extending between the first and second ends. Preferably, the first end 30 is bent orthogonal to the support arm 28 and the second end 32 is bent orthogonal to the support arm in the opposite direction that the first end is bent. In other words, the first end 30 extends vertically downward from the horizontal portion 34, and the second end 32 extends vertically upward from the horizontal portion. The horizontal portion 34 can also include a bend intermediate the ends 30 and 32, wherein the bend is made such that the horizontal portion remains in the same plane and the first and second ends 30, 32 are offset from one another.
The support platform 16 is generally rectangular in shape and has a top surface 36, a bottom surface 38 and an edge 40 formed around the perimeter of the support platform. An attachment collar 42 is attached to the bottom surface 38 and has an inner diameter (I.D.) greater than the diameter of the support arm 18. The second end 32 of the support arm 18 is attached to the attachment collar 42, which is free to rotate about the second end 32, thereby allowing the support platform 16 to pivot about the second end in a plane that is orthogonal to the second end. A plurality of gussets 44 can be attached radially around the attachment collar 42 and the bottom surface 38 to add additional support to the attachment collar. A thumbscrew 46 can be threadably received in a hole formed through the side of the attachment collar 42 and is tightened against the support arm 18 to prevent the collar from rotating around the second end 32 of the support arm.
At least two, preferably, four grill mounting flanges 22 are attached to the top surface 36 of the support platform 16 to which the grill 20 is fixedly attached to by a plurality of fasteners 24, such bolts. The support platform 16 is of a length greater than the length of the grill 20 attached thereto. Preferably, the support platform 16 is at least 1.5 times the length of the grill and the grill mounting flanges 22 are positioned towards one side of the support platform, with two of the flanges positioned juxtaposed along an edge thereof with the opposite two flanges attached juxtaposed to the support platform at a spaced distance substantially equal to the length of the grill 20. With the grill 20 positioned towards one side of the support platform 16 a free workspace is provided along side the grill.
Turning to FIGS. 6 and 7, the pivot mount assembly 26 is attached to the first end 30 of the support arm 18 and is used to mount or otherwise attach the second end of the support arm to a vehicle bumper. More particularly, the pivot mount assembly 26 includes a first clamp means 48 for clamping the pivot mount assembly to the bumper of a vehicle and a pivot collar 50 is attached to the clamp means 48. The pivot collar 50, having an ID greater than the diameter of the support arm 18, is attached to the first end 30 of the support arm so that the first end is rotatable within the pivot collar, thereby allowing the support arm to pivot about the pivot collar. A second thumbscrew 52 is threadably received by a hole formed through the side of the pivot collar 50 and is tightened to prevent the support arm 18 from pivoting about the pivot collar. A first retaining ring 53 may be attached to the first end 30 above the pivot collar 50 to provide a bearing surface for the support arm to pivot about the pivot collar and to prevent the second end from egressing into the pivot collar beyond a desired distance. A second retaining ring 54 can be secured to the distal end of the second end 30 of the support arm 18 to prevent the second end from being removed from the pivot collar 50.
Turning to FIGS. 8 and 9, the retaining mount assembly 28 is provided to retain the support arm 18 in a position against or parallel to the vehicle bumper for transport or when the grill 20 is not in use. The retaining mount assembly 28 includes a second clamp means 56 for attaching the retaining mount assembly to the vehicle bumper and a receiver member 58 for receiving a longitudinal section of the horizontal portion 34 of the support arm 18. The receiver member 58 is generally U-shaped with a pair of legs defining an open space therebetween, with the open space of a distance that is greater than the diameter of the support arm 18. An end of one of the legs of the receiver member 58 can be bent slightly outwards in a direction away from the other leg, thereby making insertion of the longitudinal section of the horizontal portion 34 of the support arm 18 into the receiver member easier. In addition, the horizontal portion 34 may have a through-hole 60 formed therethrough and the receiver member 58 may have cooperating through holes 62 formed through each leg for receiving a pin 64 to lock the support arm 18 to the receiver member 58.
The first and second clamp means 48 and 56 for attaching the pivot mount assembly 26 and the retaining mount assembly 28 respectively to the vehicle bumper each include a first clamp member 66 and a second clamp member 68. The first clamp member 66 is generally U-shaped having a pair of parallel legs with orthogonally bent ends 70 each end having a hole formed therethrough. The second clamp member 68 is generally flat and rectangular shaped and includes two holes one formed through each end of thereof to cooperate with the holes formed through the ends of the first clamp member 66. The U-Shaped portion of the first clamp 66 member is sized to receive a longitudinal section of a vehicle bumper therein and the second clamp member 68 being secured to the first clamp member sandwiching the bumper therebetween. The first and second clamp members 66 and 68 are secured to each other by passing a fastener, such as a bolt, through each cooperating hole formed in the first and second clamp members.
While the first and second clamp means are described in detail, the specific structure of each clamp means can be substituted for an equivalent structure serving the same function of attaching the pivot mount assembly 26 and retaining mount assembly 28 to a vehicle bumper without departing from the true scope of the invention.
Now referring to FIG. 10, the support platform 16 is shown in multiple positions pivoted about the second end 32 of the support arm 18 and the support arm is shown in multiple positions pivoted about the pivot collar 50 to illustrate the versatility in being able to position the grill mounting apparatus for convenient usage.
While a preferred embodiment of the grill mounting apparatus for a vehicle has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. 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 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 modifications 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 modifications and equivalents may be resorted to, falling within the scope of the invention.
