BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to skateboard wheels and more specifically it relates to a skateboard wheel system for providing a skateboard wheel rim that can be uniquely designed while permitting easy replacement of worn wheels.
2. Description of the Related Art
Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
Skateboard wheels have been in use for years. Typically, skateboard wheels are comprised of a urethane material and have enclosed bearing casings pressed within the wheels. The wheels can be made of most any color and have different artwork or color patterns impregnated within the urethane material. However, when skateboard wheels used today wear out, the entire wheel assembly including bearings is usually discarded even though the bearings are still in working order.
While these devices may be suitable for the particular purpose to which they address, they are not as suitable for providing a skateboard wheel rim that can be uniquely designed while permitting easy replacement of worn wheels. Current skateboard wheels don't allow for designer rim usage nor do they permit for only the wheel being replaced when worn.
In these respects, the skateboard wheel system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of providing a skateboard wheel rim that can be uniquely designed while permitting easy replacement of worn wheels.
BRIEF SUMMARY OF THE INVENTIONIn view of the foregoing disadvantages inherent in the known types of skateboard wheels now present in the prior art, the present invention provides a new skateboard wheel system construction wherein the same can be utilized for providing a skateboard wheel rim that can be uniquely designed while permitting easy replacement of worn wheels.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new skateboard wheel system that has many of the advantages of the skateboard wheels mentioned heretofore and many novel features that result in a new skateboard wheel system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art skateboard wheels, either alone or in any combination thereof.
To attain this, the present invention generally comprises a rim member, manufactured in a plurality of designs and appearances, with a bearing pressed into both a first end and a second end and wheel member pressed about the rim member retained by a ring member. The rim member is comprised of an aperture for mounting the skateboard wheel system to the truck of the skateboard, a flange element located towards the first end for retaining the wheel member and first threads towards the second end for retaining the ring member. The wheel member has a rib integrated to an interior surface for retaining it to the rim member. The ring member includes a plurality of tool apertures to be utilized while assembling the ring member to the rim member.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and that will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.
A primary object of the present invention is to provide a skateboard wheel system that will overcome the shortcomings of the prior art devices.
A second object is to provide a skateboard wheel system for providing a skateboard wheel rim that can be uniquely designed while permitting easy replacement of worn wheels.

BRIEF DESCRIPTION OF THE DRAWINGSVarious other objects, features and attendant advantages of the present invention will become fully appreciated as the same becomes better understood when considered in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein:
A. Overview
Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views,
B. Rim Member
The rim member 20 is preferably made of rigid material that will not significantly distort when machined or while supporting the components of a skateboard, the user and dynamic loads observed during use. The rim member 20 is preferably made of a material which will withstand periods of exposure to moisture and contaminants (e.g. dirt or sand) such that it will not rust or wear. The rim member 20 may additionally be coated with a finishing material which must adhere to the rim member 20 and withstand exposure to moisture. The rim member 20 is preferably comprised of an aluminum material constructed using a machining or casting process, but it can be appreciated by one skilled in the art that other materials (e.g. steel or titanium) or processes could be utilized.
The rim member 20 is somewhat of a cylindrical structure having substantially circular cross sections. As shown in
The diameter and width of skateboard wheels vary for the function desired by the user. Accordingly, the rim member 20 of the skateboard wheel system 10 will vary to match or fit a chosen wheel member 30. Wheel members 30 will be discussed in more detail in the next section.
As best illustrated in
As shown in
As illustrated in
C. Wheel Member
The wheel member 30 is preferably made of a semi-rigid material that will not significantly distort when supporting the user and dynamic loads observed during use. The wheel member 30 is preferably made of a material which will withstand exposure to moisture and humidity such that it will not rust or absorb water. The wheel member 30 is also preferably made of a material which will not degrade after long exposure to sunlight. The wheel member 30 is preferably comprised of a urethane material and it can be appreciated by one skilled in the art that there are many different urethane blends and other composite blends available in many colors for skateboard wheels.
As discussed earlier, wheel members 30 are available in varying outer diameters and widths to accommodate different riding conditions or functions observed by the user. Wheel member 30 outer diameters range from approximately 52 millimeters for general usage to 60+ millimeters for more specialty riding. Wheel member 30 widths vary as desired, with wider widths providing more control of the skateboard and narrower widths used for faster applications.
The hardness or durometer of the wheel members 30 can also vary as desired by the user. A softer wheel member 30 material will provide a smoother ride and provide better grip when using a skateboard. A harder wheel member 30 material will provide a faster ride and will wear less than a softer material. A durometer around 90 A around is used for general applications while a durometer of approximately 100 A is used for more experienced users.
As best shown in
D. Ring Member
The ring member 40 is preferably made of rigid material that will not significantly distort when machined or while supporting the user and dynamic loads observed during use. The ring member 40 is preferably made of a material which will withstand periods of exposure to moisture and contaminants (e.g. dirt or sand) such that it will not rust or wear. The ring member 40 may additionally be coated with a finishing material which must adhere to the rim member 40 and withstand exposure to moisture. The ring member 40 is preferably comprised of an aluminum material constructed using a machining process, but it can be appreciated by one skilled in the art that other materials (e.g. steel or titanium) could be utilized.
The ring member 40 has second threads 42 located on the inner surface or inside diameter as best shown in
As shown in
E. Operation of the Invention
In use, the skateboard wheel system 10 is preferably used in a set of four to support a skateboard. Each skateboard wheel system 10 can be assembled to the axle portions of the trucks 14 attached to the bottom of a deck 12 as shown in
The initial step of using the skateboard wheel system 10 is to determine what riding conditions and/or functions the user will require. This allows the user to select a wheel member 30 with the proper sizing and hardness that will best fit the required needs of the user. After the wheel member 30 is selected, the rim member 20 can be selected to properly fit the chosen wheel member 30. As shown in
As best shown in
The next stage of the assembly process is to attach the ring member 40 to the rim member 20 as shown in
When a wheel member 30 is worn and needs to be replaced, the above process is reversed for disassembly. The ring member 40 is first removed from skateboard wheel system 10 by using the tool member 50, only turning in counter clock-wise direction. After the ring member 40 has been removed, the worn wheel member 30 can be removed by sliding the wheel member 30 off the second end 23 of the rim member 20. With the worn wheel member 30 removed, a replacement wheel member 30 can be assembled back onto the rim member 20 and the above process repeated for assembly.
