    APPLICATION FOR CANADIAN LETTERS PATENT SPECIFICATION TO ALL WHOM IT MAY CONCERN: BE IT KNOWN THAT I, ALLAN EUGENE FOSTER, a resident Of Canada, have invented new and useful improvements in a BUMPER FOR ELEVATED VEHICLES of which the following is a specification: BACKGROUND OF THE INVENTION Related Application This application is a division of co-pending Canadian Patent application number 2,437,055 filed 08/14/2003 entitled Attachment Means for Facilitating User Access to Vehicle Platforms,the subject matter of which is incorporated herein by reference. Field of the Invention The present invention relates to a bumper for elevated vehicles and more particularly pertains to protecting automobiles with relatively low bumper heights in collisions. Description of the Prior Art The use of vehicle bumpers is known in the prior art. More specifically, vehicle bumpers previously devised and utilized for the purpose of protecting vehicles are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements. By way of example, United States Patent Number 6,170,843 to Maxwell et al discloses a trailer hitch step. United States Patent Number 6,170,842 to Mueller discloses a Step System on Vehicle Bumper For Accessing Truck Beds and Methods of Making and Operating the Step System. United States Patent Number 6,237,927 to Debo discloses a Pull Out Tailgate Step. United States Patent Number 5,897,125 to Bundy discloses a Swivel Truck Step. United States Patent Number 5,738,362 to Ludwick discloses a Rotating Step for a Trailer Hitch. United States Patent Number 5,732,996 to Crafty et al. discloses a Tailgate Step. United States Patent Number 5,716,064 to Frerichs discloses a Truck Bed Pull Out Step System. United States Patent Number 5,617,930 to Elia discloses a Ladder Assembly for a Tailgate of a truck. United States Patent Number 3,758,134 to Stewart discloses a Breakaway Step for High-Clearance Vehicles. Canadian Patent Number 1,058,251 to Kirkpatrick discloses a pivoting step for high ground clearance vehicles. Lastly, Canadian Patent Number 1,219,020 to Yong discloses a truck step. While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a bumper for elevated vehicles that protects automobiles with relatively low bumper heights in collisions. In this respect, the bumper for elevated vehicles 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 protecting automobiles with relatively low bumper heights in collisions.
    Therefore, it can be appreciated that there exists a continuing need for a new and improved bumper for elevated vehicles which can be used for protecting automobiles with relatively low bumper heights in collisions. In this regard, the present invention substantially fulfills this need. SUL~IARY OF THE INVENTION In view of the foregoing disadvantages inherent in the known types of vehicle bumpers now present in the prior art, the present invention provides an improved bumper for elevated vehicles. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved bumper for elevated vehicles and method which has all the advantages of the prior art and none of the disadvantages. To attain this, the present invention essentially comprises a frame mounted mini bumper as an "accessory receiver". This mini bumper is essentially an additional bumper mounted under or lower that the original bumper, and is added to the front or rear of a high platform vehicle, having a rearward facing receiver centered in the bumper face, and two opposed openings "accessory receivers" facing left and right at the extreme ends of the mini bumper Into these horizontal "accessory receivers" accessories such as a rotatable step of the line may be installed. The mini bumper is mounted to the frame of the vehicle platform in the same fashion as standard trailer hitches, using similarly formed steel plate brackets, in it's present embodiment, giving substantial support to the mini bumper for it's dual purpose of "accessory receiver" and as a bumper. A four-wheeled vehicle, having a top of platform height (tailgate height) of thirty six inches may have a bumper height of thirty two to twenty four inches above the ground, placing it several inches above the bumper height of a conventional automobile. With safety as a major consideration, a mismatched bumper height means that the automobile's bumper will slide under the high truck bumper with considerable damage to the auto and possible severe personal injury to it's occupants. If, however, the truck were equipped with a mini bumper instead of the currently standard trailer hitch, the bumper height mismatch would not exist, since the mini bumper would be the same height as the automobile bumper. In this invention there is a pivot pin. Also there is a pivot pin extension bar assembly, which are attached to the "accessory receiver", which is hereinafter referred to as the "pivot pin bar". The pivot pin and pivot pin bar consists firstly of an extension bar adapted to fit within the accessory receiver, and is secured thereto by means of a hitch pin. This extension bar is essentially parallel with the rear of the vehicle and normally below the vehicle bumper location. At the distal end of the extension bar is located a vertical pivot pin on which the pivot step can be rotated in a horizontal plane into it's several working positions and it's stowage position. Pivot pin bars fit into either the right or.left receiver of the accessory receiver, giving flexibility of installing a pivot step on either side of the vehicle platform. Such an arrangement allows a user to employ the step to the right or the left of the mini bumper. A user may also place the step on both sides of the mini bumper. The improved bumper for elevated vehicles embodying the principles and concepts of the present invention will be described. The present invention, the bumper for elevated vehicles is comprised of a plurality of components. Such components are individually configured and correlated with respect to each other so as to attain the desired objective. First provided is a vehicle, having a front and rear and frame. There is next provided a pivot pin bar, pivot pin, and a pivot step. The pivot bar may be installed from either the left of the right, thereby enabling installation of a pivot step on either side of a vehicle. The mini bumper is coupled with the vehicle. The mini bumper may be mounted directly to the frame of the vehicle, or it may be mounted using an adaptive bracket, also called an attachment member. The mini bumper has accessory receivers that are formed as an integral part of the mini bumper shell. There is a mini bumper shell stiffener. The accessory receivers are entered from the side or the end of the bumper, as shown in Figure 2. There are mini bumper frame attachment member, as shown in Figure 1. The frame has frame holes that are aligned with attachment member hole. The pivot bar has parts that are inserted into the mini bumper receiver. A fastening device passes through hole into the shell, and holes in the pivot pin bar make a secure connection. Asafety step having parts, and may be attached to the mini bumper by inserting pivot pin into hole of the step assembly. A standard hitch pin and clip complete the assembly by being inserted into one of the four indexing holes and the index locking hole located on the pivot pin bar. If desired, a safety handle can be added at any time by the user. The step assembly may be rotated and locked into any one of four working and stowage positions. The fabrication details of the mini bumper are shown in Figure 1 with an isometric view from the rear and under the mini bumper. The main body or shell of the mini bumper is formed as a "C" or channel with the bottom leg turned up ninety degrees to form a three sided receptacle into which accessories such as a pivot pin bar may be inserted. Further, a hole is formed, centered left to right, and at the top of the face of the mini bumper, into which a tubular center receiver can be flush mounted with the face of the mini bumper shell. The two shell stiffeners, in this embodiment are welded at ninety degrees to the back of the face of the shell and in alignment with the two frame connectors. Afurther stiffener is secured to and becomes an integral part of the top edge of the mini bumper shell, and is welded in this embodiment, to the shell stiffeners as well as the shell itself to provide a substantial support for the center receiver, which is also welded to member; and to the shell. Beneath the receiver is positioned the safety chain plate with two holes, to receive the safety chain fasteners. Holes on either side of the center receiver, in the face of the shell are to provide access to the hitch pin hole and to allow the safety chain to be fastened to the holes. It should be noted that the face of the mini bumper is free of any obstructions, such as receivers or a safety chain plate. The mini bumper is designed to match the bumper height of automobiles and to create a less dangerous and costly collision, should one occur. The mini bumper can, with its center receiver and.two side accessory receivers, become the next generation of trailer hitches. Figure 5 shows a full width version of the mini bumper 80 in place on the back of a pickup truck, with a center receiver and two rearward facing accessory receivers, all with flush mounts and easily accessible safety chain plates. Figure 6 has a rear view of the two ends of the full width bumper 80 showing he "accessory receiver" parts assembly on the left and the completely assembled "accessory receiver" on the right. The receiver tube is welded into hole in the face of the shell. The receiver tube also is welded to the turned up leg of the shell. Aheavier gauge metal plate encircles the receiver tube and is welded to it as well as to the top and bottom of the rear of the full width shell. This same plate serves as the safety chain plate, with holes exposed under the face of the lower bumper for easy attachment of the safety chains. This full width lower bumper also has a frame support system as shown on Figure 1 of the mini bumper drawings, giving it the same structural pport that current trailer hitches have, enabling it to do all of the functions of a receiver type trailer hitch plus providing a lower safety bumper with a protrusion free surface. Figure 7 shows a mini bumper utilized for mounting two different rotatable accessory devices. On the left, mounted in the receiver opening and secured by bolts with nuts going through holes, is a pivot pin bar assembly, onto which is couple the step assembly. As in previously presented designs, the bushing hole is mounted on the pivot pin, and a hitch pin secures the step in one of the working or stowage positions by being inserted into one of the four index holes and the locking hole. On the right side of the mini bumper an identical except slightly longer, pivot pin bar, having parts, is inserted into the receiver opening. On this pivot pin a rotary cargo tray is installed, using bushing hole, with a similar index locating plate having a choice of three locking holes, with three corresponding stationary cargo tray positions. The cargo tray positions are:(A.) travel position-covering the full width of the truck or other vehicle with a rear door access, and occupying less in depth; (B.) rear door access position-in situations where the cargo tray 120 is loaded and rear door access is required, the cargo tray 120 can be unloaded and dismantled or it may be pivoted out of the way ninety degrees, using prior art; (C.) loading or unloading position from another vehicle parked parallel and forward of the cargo tray equipped vehicle. The Cposition for the cargo tray is achieved by rotating the tray one hundred and eighty degrees from the travel position behind the truck or van. Included in Figure 7 is a pivot platform support which is insertable into a center receiver or an accessory receiver. The receiver insertable bar having a hitch pin securing hole .also has a vertical member to attain the correct height, and an engagement plate with a pin locking hole 119. In use the "pivot platform support" is inserted and locked in a receiver with a hitch pin and the cargo tray, or pivot platform rests on the engagement plate with holes being penetrated by a hitch pin, to provide a secure support for the rotatable cargo tray, while the vehicle is traveling.
