Description: TIRE PRESENTER FIELD OF THE INVENTION The present invention relates to a spare wheel storage apparatus for moving a spare wheel from an under vehicle body position to a wheel unloading position along a path of travel, and in particular, to a device for presenting the spare wheel extending at least partially external of a vehicle body vertical contour when the spare wheel is in the unloading position after traveling along the path of travel having a non-vertical component of travel. BACKGROUND OF THE INVENTION Spare wheel storage in a vehicle has always been a problem. Designers have found it exceedingly difficult to mount the spare wheel so as to make it accessible and easy to retrieve and replace. Mounting the spare wheel in a location under the vehicle body for storage requires the addition of a tire lift-and-carry device, such as a spare tire carrier and winch. A suitable example of a spare tire carrier and winch can be found in U.S. Patent No. 5,228,661. The inherent problem with spare tire carriers and winches of this type, and the under vehicle body storage location, is that the winch is capable of only lifting, lowering and/or carrying the spare wheel in a generally vertical line essentially directly below and in line with the drum of the winch. This limitation requires an individual operator to reach under the vehicle body in order to pull or drag the spare wheel out from under the vehicle from its position generally directly below and in line with the drum of the winch. Therefore, it is desirable in the present invention to provide a spare wheel presenter capable of presenting a spare wheel extending at least partially external of a vehicle body vertical contour when the spare wheel is in the wheel unloading position after having traveled along a path from an under vehicle body storage position. SUMMARY OF THE INVENTION According to the present invention, a spare wheel storage apparatus is provided for moving a spare wheel from an under vehicle body storage position to a wheel unloading position along a path of travel. The storage apparatus includes winch means for raising and lowering the wheel to and from the storage position. The winch means includes an elongated, flexible member connected to a wheel engaging member. Wheel presentation means is provided for presenting the wheel extending at least partially external of a vehicle body vertical contour when the wheel is in the wheel unloading position. The path of travel has an upper, generally vertical, region of travel and a lower, presentation region of travel. The presentation region of travel is a non-linear region of travel. The presentation region of travel has a vertical component and a non-vertical component of travel. The wheel presentation means may include at least one elongated, flexible member connected to a wheel engaging member at one end and connected to an under vehicle body portion at an opposite end. The elongated, flexible member is connected to the under vehicle body portion at a position disposed between the storage position and the vehicle body vertical contour. Preferably, the flexible member is rotatably connected to the wheel engaging member. In the preferred embodiment of the present invention, first and second elongated, flexible members are provided. Each of the first and second elongated, flexible members is connected to the wheel engaging member at one end and connected to an under vehicle body portion at an opposite end. The first and second elongated, flexible members are connected to the under vehicle body portion at, positions disposed between the storage position and the vehicle body vertical contour. The opposite ends of the first and second elongated, flexible members are preferably level with one another, spaced laterally from one another and centered with respect to the path of travel for lateral stability of the wheel during travel from the storage position to the unloading position. Preferably, the first and second elongated, flexible members are rotatably connected to the wheel engaging member. Other objects, advantages and applications of the present invention will become apparent to those skilled in the art when the following description of the best mode contemplated for practicing the invention is read in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT The present invention relates to a spare wheel storage apparatus 10, sometimes referred to as a spare tire lift-and-carry apparatus for use on a vehicle 12. Typically, a spare wheel storage apparatus 10 includes a rotatable input shaft 14 supported by a housing 16. Various types of spare , tire lift-and-carry devices 10 can be used advantageously in combination with the present invention. By way of example, and not limitation, a suitable spare tire carrier and winch is disclosed in U.S. Patent No. 5,228,661, which is incorporated herein by reference. Any details regarding the specific construction and operation of a typical spare tire carrier and winch can be obtained through review of the aforementioned patent. The present invention addresses the problem of presenting a spare wheel to a vehicle operator, when needed in a wheel unloading position which is convenient and easy for the vehicle operator to have access to the spare wheel for disengagement from the carrier and winch by further manual manipulation. Wheel presentation means 18 is provided according to the present invention for presenting a spare wheel 20, typically including the combination of a tire 22 and rim 24, extending at least partially external of a vehicle body vertical contour 26, such as a bumper or other external vehicle body panel, when the wheel 20 is in a wheel unloading position 28 as illustrated in solid line in Figure 1. The spare wheel storage apparatus 10 according to the present invention moves a spare wheel 20 from an under vehicle body storage position 30 to a wheel unloading position 28 along a path of travel as illustrated by the intermediate position shown in phantom at 32 of Figure 1. The storage apparatus 10 may include means 34 for raising and lowering the spare wheel 20 to and from the storage position 30. The means 34 may include a winch having an elongated, flexible member 36 connected to a wheel engaging member 38. Typically, the wheel engaging member 38 engages with the rim 24 to lift the spare wheel 20 to the desired position. The winch, or other means 34, typically is designed to hold the spare wheel 20 in the desired position after having raised the spare wheel 20 to the under vehicle body storage position 30. The wheel presentation means 18 preferably includes at least one elongated flexible member 40 connected to the wheel engaging member 38 at one end and connected to an under vehicle body portion 42 at an opposite end. Preferably, the flexible member 40 is connected to the vehicle body portion 42 at a position disposed between the storage position 30 and a vertical plane corresponding to an outermost or external periphery of the vehicle body contour 26. In the preferred configuration illustrated in Figure 2, first and second elongated, flexible member, 40 and 44 respectively, are provided connected to the wheel engaging member 38 at one end and connected to a vehicle body portion 42 at an opposite end. Each of the first and second elongated, flexible members, 40 and 44 respectively, are connected to the vehicle body portion 42 at positions disposed between the storage position 30 and the vehicle body vertical contour 26. The first and second elongated, flexible members, 40 and 44 respectively, have opposite ends that are preferably level with one another, spaced laterally from one another, and centered with respect to a path of travel for the spare wheel 20 for providing lateral stability of the spare wheel 20 during travel from the storage position 30 to the unloading position 28. Preferably, the first and second elongated, flexible members, 40 and 44 respectively, are rotatably connected to the wheel engaging member 38. The wheel presentation means 18 modifies the path of travel of the spare wheel 20 from its straight up and down vertical path of travel, typical of a winch-type lift-and-carry mechanism, such that the path of travel has an upper, generally vertical, region of travel and a lower, presentation region of travel. The presentation region of travel having a curved path with a vertical component and a horizontal component of travel. According to the present invention, the spare wheel storage apparatus 10 of the present invention includes means for moving a spare wheel 20 between a storage position 30 and an unloading position 28 along a path of travel, and wheel presentation means 18 for presenting the wheel extending at least to a partially exposed unloading position from underneath the vehicle, wherein the spare wheel 20 a portion protruding outwardly with respect to a vertical plane corresponding to an outermost external periphery of the vehicle body contour 26 providing easy access to the vehicle operator, and without requiring the vehicle operator to reach underneath the vehicle in order to remove the spare tire from the storage apparatus 10. The presentation region of travel preferably has a vertical component and an non- vertical component of travel. The presentation region of travel also preferably is a non-linear region of travel. Preferably, the flexible member is a cable or pair of cables attached to the rim retainer or other wheel engaging member and also attached to the rear of the vehicle. If required, a pulley 46 can be supplied adjacent the winch to better guide the cable into the winch and to prevent cross threading. This facilitates a "clean clothes" operation of the spare tire carrier by adding a mechanism to lower the tire and present it to the operator, by moving the wheel toward the operator, thereby eliminating the need for the operator to reach under the vehicle to retrieve the spare tire when lowered.
