The present invention relates to a covering for the exterior surfaces of a vehicle wheel to improve its appearance and in particular to a non-removable wheel covering.
It is a common desire for vehicle owners who take pride in their vehicle to improve the appearances of the vehicle. Often, the most unsightly portion of a vehicle is the wheels, because the wheels are functional. Automobile manufacturers customarily provide wheels covers for their vehicles to enhance the appearance of the wheels, but wheel covers are not generally provided by the manufacturers of trucks and therefore truck wheels do not have surfaces adapted to retain a wheel cover thereto. The wheel covers for trucks, therefore, are provided by aftermarket manufacturers and the wheel covers they provide must attach to the function portions of the wheel.
There are many methods for attaching a wheel cover to the functional portions of a wheel. The wheel cover may have a plurality of spaced holes for receiving the threaded studs that retain the wheel to the axle of the vehicle such that the studs and nuts which retain the wheel to the hub of the vehicle also retain the wheel cover. Certain states, for example California, however, require that truck wheels be periodically inspected for cracks that occur in the vicinity of the holes that receive the studs. Where portions of the web are covered by the retainer for retaining the wheel cover, the retainer must be removed to inspect the web in the proximity of the holes. The nuts that retain such wheels to the hub of trucks are installed using a pneumatic or hydraulic tool and therefore the removal of lug nuts retaining a wheel to expose the underlying web require that the truck go off-road to a remote location. As a result, the use of the studs and lug nuts which retain the wheel to a truck to retain a cover can cause an unacceptable delay in the use of the truck.
Another method for retaining a cover to a truck wheel is disclosed in my previously issued U.S. Pat. No. 5,630,653 issued May 20, 1997 in which an attachment plate is provided having arcuate portions that fit under the corners of a lug nut. Such an attachment can be removed without requiring the removal of the lug nut that holds the wheel to the vehicle.
Another method of retaining a wheel is disclosed in my U.S. Pat. No. 6,595,961 B1 issued in which a retainer is connected to portions of the threads of one or more studs that extend beyond the lug nut that retains a wheel to an axle hub. A third method of retaining a wheel is disclosed in my U.S. Pat. No. 5,823,635 in which the wheel is attachable to hand holds provided in the web of the wheel. Yet another method of attaching a wheel is disclosed in my U.S. Pat. No. 6,443,528 in which retaining brackets are provided that extend into a drop center of a truck wheel. In all of these methods, the wheel covers and their retainers can be removed without requiring the removal of the nut threaded onto the studs that retain the wheel to the vehicle.
Existing wheel covers for vehicles, including automobile wheel covers, must be removed before the wheel itself can be removed. In the case of truck wheels, the apparatus that retains the cover to the truck wheel can be complex and time consuming to remove before the wheel can be removed from the vehicle, and time consuming to reinstall the cover after the wheel has been replaced. It would be desirable, therefore, to provide a wheel covering which can be permanently attached to a wheel and will improve the appearance of the visible portions of the wheel, and will continue to be retained to the wheel when the wheel is removed from the vehicle. To comply with the laws of various states requiring the inspection of a wheel in the vicinity of the holes that receive the studs it is desirable that the wheel liner not conceal the portions of the wheel that may require inspection.
Briefly, the present invention is embodied in a method for covering the visible portions of a wheel of a vehicle. The vehicle may be that of automobile or that of a truck, or any other vehicle for which one desires to enhance the visible portions of the wheel. In the case of the rear wheels of a truck, the wheel has a tubular rim portion, having an inner surface that is visible from the exterior of the truck and a web portion having an outer surface which is also visible from the exterior of the truck.
In accordance with the invention, a wheel liner is provided having a generally tubular portion, the outer surface of which is generally complementary in shape to the visible inner surface of the tubular rim, and across the rearward end of the cylindrical portion of the cover is a generally planar web that is complementary in shape to the outer surface to the outer surface of the web of the wheel to which it is attachable. The tubular portion of the wheel liner is adapted to permit the rearward surface of the web of the wheel liner to abut against the outer surface of the web of the wheel and is nonremovably retained in abutting relationship by a bonding material. To ensure that the portions of the wheel in the proximity of the holes for receiving lug nuts are not concealed, the wheel liner will preferably have a plurality of spaced openings around the central portions of the liner positioned to receive the threaded studs with the diameters of the holes being sufficiently large to permit inspection of the underlying wheel in the proximity of the lug nut.
Where the rear wheel of the truck is adapted to receive a tubeless tire, as is the case with most wheels, the wheel will have a drop center having an inner diameter that is smaller than an inner diameter taken rearward of the drop center. In order to provide a wheel liner that is insertable into a wheel having a drop center, the wheel liner must have a cylindrical portion, the outer diameter of which is no larger than the inner diameter of the dropped center. Accordingly, the tubular portion of the wheel between the drop center and the web will not abut against the inner surface of the wheel. A suitable bonding material, such as a double sided adhesive tape, positioned between the web of the wheel and the web of the wheel liner retains the wheel cover to the wheel.
It should also be appreciated that in order to remove a tire from a wheel, a tool must engage the curled outer rim of the wheel and therefore a wheel cover in accordance with the present invention must not cover the portions of the curl at the rim of the wheel that is engagable by the tool.
A better understanding of the present invention will be had after a careful reading of the following detailed description taken in conjunction with the drawings wherein:
Referring to
For the purposes of this discussion, the elements of a wheel and wheel liner that are positioned outward of the vehicle to which they are attached will be described as “forward” and the portions of the wheel or wheel or wheel liner that are directed toward the vehicle to which they are attached will be referred to as “rearward.”
A wheel liner 30 in accordance with the invention has a generally planar web portion 32 and extending forwardly from the outer circumference of the web portion 32 is a tubular portion 34. The wheel liner 30 is preferably made of a stamped metal having an outer shape adapted to slide within the interior of the cavity formed by the rim 14 of the wheel 10. In the preferred embodiment, the tubular portion 34 of the liner 30 has a central portion 36, the outer diameter of which is a little smaller than the inner diameter of the dropped center 18 of the rim 16, such that the rearward portions of the wheel liner 30 will snugly slide inside the dropped center 18 of the wheel 10. At the forward edge 38 the diameter of the tubular portion 34 is a little less than the inner diameter of the lip 16 at the outer end of the rim 14 of the wheel 10. The tubular portion 34 has an axial length 40 which is a little less than the axial length 42 of the inner portions of the rim 16 of the wheel 10. The tubular portion 34 of the wheel liner 30 also has a tapering portion 44 between the central portion 36 and the web 32 adapted to permit the wheel liner 30 to fit within the cavity of the wheel 10 with the rearward surface 46 of the web 32 of the wheel liner 30 abutting against the outer surface 28 of the web 12 of the wheel 10, while the forward edge 38 of the wheel liner fits within the lip 16 of the wheel 10 as shown in
In accordance with the invention, the rearward surface 46 of the web 32 of wheel liner 30 is adapted to abut against the forward outer surface 28 of the web 12 of the wheel and a suitable adhesive is applied between the two surfaces to retain the wheel cover 30 to the wheel 10. I have found that one means of permanently securing a wheel liner 30 into the cavity of wheel 10 is to apply a double sided tape 45 to the forward surface of the web 12 of the wheel 10 and thereafter pressing the rearward surface 46 of the web 32 of the wheel liner 30 against the exposed adhesive material of the double sided tape 45 to thereby retain the parts together.
Where the outer diameter of the central portion 36 of the wheel liner 30 is in close proximity to the inner diameter of the drop center 18, an adhesive 50, preferably in the form of a gel, can be applied to the parts prior to assembly to bond the outer surface of the central portion 36 of the wheel liner 30 to the drop center 18 of the wheel 10, thereby further securing the wheel liner 30 into the cavity of the wheel 10.
In the preferred embodiment, the wheel liner 30 has a central opening 52 sized to receive the central portions of the hub of a vehicle and surrounding the central opening 52 is a plurality of spaced holes 54-54 configured to received the studs, not shown, that retain the wheel 10 to hub, not shown, of the vehicle. Preferably, the spaced holes 54-54 have inner diameters that are sufficiently large to permit the inspection of the underlying metal of the wheel 10 in the proximity of the holes 26-26 in the wheel 10 that receives the studs. The holes 54-54 must, therefore, have a diameter larger than the widest diameter of the lug nuts retaining the wheel 10 to the vehicle to thereby leave a portion of the underlying metal of the wheel surrounding the lug nut visible for inspection.
Once the wheel liner 30 is installed into the cavity of the wheel 10, it will remain installed as a permanent part of the wheel 10 for the remainder of its useful life. Removal of the wheel 10 from the vehicle will not require the removal of the wheel liner 30 from the wheel 10.
A second embodiment of a wheel liner 30′ in accordance with the invention is depicted in
In this second embodiment, a plurality of spring clips 56-56 are provided around the outer surface of central section 36′ of the tubular portion 34′ of the wheel liner 30′. The spring clips 56-56 are biased to be compressed against the inner shoulder 20 of the wheel 10 to thereby provide support to the tubular portion 34′ of the wheel liner 30′ when the wheel liner 30′ is inserted into the cavity of the wheel 10. The spring clips 56-56, therefore, are an alternative to the application of an adhesive, such as the gel adhesive 50 applied between the central section 36 of the wheel liner 30 and the drop center 18 of the wheel 10.
Yet a third embodiment of a wheel liner 30″ in accordance with the invention is depicted in
It should be appreciated that many different types and makes of trucks are manufactured to receive the same size tire and the wheels of the various truck manufacturers intended to receive the same size tire appear to the naked eye to be identical to one another. Even though they may appear to be identical, some of the dimensions of the inner surfaces of the rim 14 of the various wheels are different from one another. The outermost dimensions of the tubular portion 34, 34′, 34″ of a wheel liner 30, 30′, 30″ can be made to fit the smallest of the wheels 10 manufactured to receive a given sized tire, such that the same wheel liner 30, 30′, 30″ may be used to fit all wheels of a given size regardless of the manufacturer.
It should also be appreciated that the present invention can be employed to provide a wheel cover to the front wheels of a truck. Referring to
While the present invention is described with respect to a plurality of embodiments, it will be appreciated that many more modifications and variations may be made without departing from the true spirit and scope of the invention. It is therefore the intent of the appended claims to cover all such modifications and variations which fall within the true spirit and scope of the invention.
