Automotive wheel overlay attachment system

Abstract

A vehicle wheel overlay attachment system disclosed herein provides for wheel overlays, or wheel skins, that are readily installable over existing wheels by securing directly to a wheel center cap. The center cap is adapted to be inserted into the center hub portion of the wheel, much like a traditional center cap, but also contains a system for securing a wheel overlay to the center cap. When properly installed on the center cap, the wheel overlay will be snugly positioned over the wheel thereby changing the appearance of the vehicle wheel.

Description

The present disclosure relates to wheel overlays for automotive and other vehicle wheels and more specifically to functional and aesthetic improvements to known overlays for automotive and other vehicle wheels.

BACKGROUND

Known wheel overlays are deficient in that they do not provide efficient or effective fastening to the underlying wheel of an automobile or other vehicle. Wheel overlays are also sometimes referred to as wheel skins. Specifically, known wheel overlays do not provide fastening mechanisms that are easily attachable, do not provide fastening mechanisms that are easily removable, and do not rely on aesthetically pleasing clips or fastening members. Also, known overlays are not compatible with multiple toolings of the same wheel and the variances of those wheels since aesthetically, the wheels are the same but there can be slight differences in certain dimensions that impact the ability for the wheel overlay to attach to the wheel. What is needed is a wheel overlay system that satisfies these and other deficiencies of known automotive or other vehicle wheel overlay systems.

Simulated chrome plated wheel covers designed to be installed over standard factory wheels are known. For example, U.S. Pat. No. 6,010,196, U.S. Pat. No. 6,402,253, U.S. Pat. No. 6,409,277, and U.S. Pat. No. 6,672,678 disclose embodiments of simulated chrome plated wheel covers or overlays that rely on fasteners arranged around the outside of the wheel to affix the cover to the wheel. In some of these embodiments, the described fasteners rely on an upward extending circumferential edge on the vehicle wheel to which the fasteners may be removably affixed. Typically the wheels to which such overlays are affixed are made of steel. In these embodiments, the wheel covers would either completely cover the lug nuts, or they would have openings corresponding to the positions of the lug nuts to enable access to the lug nuts (e.g., to allow the wheel to be removed) without taking the cover off. In these embodiments, if the wheel to which the overlay is going to be affixed lacks an upward extending circumferential edge, the known cover attachment mechanisms cannot be used. These known fasteners are also not aesthetically pleasing, as they are visible on the outer rim of the wheel cover and thus disrupt the aesthetic appearance of the wheel/overlay combination.

Aluminum alloy wheels presented a different challenge for simulated wheel covers because the wheels often use spokes and do not typically have a recessed outer rim. U.S. Pat. No. 7,452,037 shows a wheel cover that may be attached to an alloy wheel by duplicating the shape of the original wheel on the interior and acting as a skin. Fasteners are generally not used to affix wheel covers to alloy wheels; instead the wheel contains slots that are used for inserting studs attached to the wheel cover. The cover substantially duplicates the entire outer surface of the wheel, however the sides of the spokes have a slight minimal gap or offset. This gap is only the width of a slot or slots provided within each spoke. When the wheel cover is placed over the wheel, a mating mushroom head stud, which may be integrally formed into the wheel overlay, is aligned with one edge of the slot and is easily inserted onto an area of the slot slightly larger than the diameter of the stud. The wheel cover is then rotated clockwise until the stud snaps into place in a smaller area of the slot, thereby changing the gap from one side of the spoke to the other. These covers may either cover the hub completely or match the contour of the hub, thereby permitting the lug nuts to be exposed for easy removal of the wheel.

Creating wheel overlays that appear to be part of the wheel when mounted to the wheel presented a challenge as well. U.S. application Ser. No. 14/559,184, assigned to the assignee of the instant application, shows a vehicle wheel overlay system that is readily installable over existing wheels by attaching directly to lug nuts, studs, or other mounting hardware used to affix the wheel itself to the body of the vehicle. The overlay system provides for a wheel overlay that can be readily removed by disengaging lips of the extension(s) of the wheel overlay from the lug nuts holding the wheel to the vehicle, thus providing easy access to the lug nuts and enabling the wheel to be easily removed from the vehicle. In some embodiments, the plurality of lug nut engaging areas for engaging with and disengaging from a corresponding extension may be designed from various shapes, including but not limited to: rounded, angled and wedge-shaped.

While this wheel overlay system represents an improvement over prior, known systems, additional improvements have nonetheless developed. The most recent challenge, which is addressed by the instant disclosure, relates to using a center cap assembly as part of the attachment mechanism. A center cap assembly may be used to securely attach a wheel overlay a wheel. In addition, there is a desire to use the original center cap so that the wheel overlay appears to be part of the original wheel. There is also a need to use multiple attachment mechanisms together to ensure the wheel overlay is securely attached to the wheel. The instant disclosure satisfies these and other problems not previously solved in the prior art.

SUMMARY

Various embodiments of the vehicle wheel overlay system disclosed herein provide for wheel overlays that are readily installable over existing wheels by attaching directly to a center cap assembly. The center cap assembly is adapted to be inserted into the center hub of the wheel, much like a traditional center cap, but also contains a mechanism or assembly for securing a wheel overlay to the center cap. When the wheel overlay is properly installed using the center cap assembly, the wheel overlay will be snugly positioned over the wheel without the drawbacks of traditional methods for affixing a wheel overlay to a wheel known in the art. The center cap assembly thus improves on prior known affixing mechanisms by ensuring that mounting forces are applied circumferentially around the wheel, as well as at the center of the wheel.

Additionally, the wheel overlay disclosed herein may have an aesthetically pleasing finish, such as a chrome plated finish or a painted finish of a different color, to add to the aesthetic appearance of the vehicle. In some embodiments, the disclosed wheel overlays are unfinished, or in a raw form, so that the consumer or an aftermarket paint specialist may paint the overlays any color or pattern desired.

The instant disclosure also advantageously provides for wheel overlays that may be used on both steel and alloy wheels since both types of wheels may be (and typically are) designed with the inclusion of a center cap used to cover the wheel hub. Moreover, since the center cap design in some embodiments does not depend on whether steel or alloy wheels are being affixed to a vehicle, the fastening mechanism for wheel overlays may be the same regardless of the material from which the wheel is constructed.

Furthermore, since wheels may vary in diameter, number of lugs nut, lug nut spacing, and outer rim design, it is advantageous to have a wheel overlay attachment system which may be readily adapted to be used with various overlay designs. An attachment system which depends on the center cap structure may be uniform in design even when other dimensions of the wheel vary, and thus provides a distinct advantage over known art.

In one embodiment, the disclosed vehicle wheel overlay attachment system includes a fastening structure corresponding to the center cap of the wheel the user wishes to be covered by the wheel overlay. In some embodiments, this wheel will include the original equipment manufacturer (“OEM”) wheel. The center cap assembly contains a system for securing the wheel overlay system to the center cap, such that the wheel overlay system is positioned over the vehicle wheel. In some embodiments, the center cap assembly will allow a second center cap to be affixed over the center cap. In one example, a user may attach a wheel overlay and wish to retain the look of the OEM center cap. This embodiment of the center cap assembly allows the user to affix both the wheel overlay and a second center cap to the wheel, the second center cap in this case being an OEM center cap.

The wheel overlays disclosed herein may also contain other mechanisms for securing a wheel overlay. For example, a wheel overlay may be designed for a wheel operating in an extreme environment, such as off road, or to contain an especially complicated design. In such embodiments additional fastening systems to attach the wheel overlay may be necessary. Thus, a wheel overlay may be configured to contain both a center cap assembly and another attachment systems or techniques known in the art.

Additional features and advantages are described herein, and will be apparent from the following Detailed Description and the figures.
