DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings, the present invention will now be described in detail with reference to the disclosed embodiments.
FIGS. 1-4 illustrate a decorative wheel apparatus 10 of the present invention. The decorative wheel apparatus 10 is shown being utilized on a wheel 12 of a vehicle (not shown). Although the decorative wheel apparatus 10 is ideally suited for use on the wheel 12 of a motorcycle (not shown), the invention is not limited to being used on a wheel 12 of a motorcycle, but rather, the decorative wheel apparatus 10 of the present invention may be utilized on other desirable wheels, such as those utilized on an automobile or other wheeled vehicles. The wheel 12 typically has a conventional tire (not shown) mounted on an outer circumference of the wheel 12. The wheel 12 is rotatably driven by an axle 14 which may be power driven by a motor and/or a drive shaft of the vehicle or may be manually driven through the use of a manually powered wheeled vehicle (not shown). The axle 14 is connected to a friction drive 16 which rotates a plurality of decorative figures 18, 52, 62 mounted within the circumference of the wheel 12. The decorative figures 18, 52, 62 may include a substantially circular, plate-like disc 18, as seen in FIGS. 1 and 2, or a pine tree shape figure 62, as seen in FIG. 3. The present invention is not limited to the above-noted shapes for the decorative figures 18, 52, 62, but rather, the present invention anticipates any design that will enhance the appearance of the wheel 12. The rotation of the decorative figures 18, 52, 62 in conjunction with the rotation of the wheel 12 provides an appearance that enhances the aesthetic appearance of not only the wheel 12, but also the vehicle.
The wheel 12 of the vehicle provides features which support the decorative wheel apparatus 10 of the present invention, as seen in FIGS. 1-4. The wheel 12 is substantially circular and has a conventional outer circumferential wheel design for supporting the mounting of the tire. The wheel 12 is coaxially mounted to the axle 14 about a rotational axis 20 of the axle 14. An inner circumference 22 of the wheel 12 provides three cut-out portions 24 for enhancing the aesthetic appearance of the wheel 12. Three spoked portions 26 are formed between the three cut-out portions 24 of the wheel 12. The three spoked portions 26 extend radially between the outer circumference 19 of the wheel 12 and the axle 14. The wheel 12 may be fabricated of various materials, such as chrome, aluminum, stainless steel, or any other metallic or high-strength material that would serve as a proper material for the wheel 12.
The wheel 12 is mounted to the axle 14 of the vehicle through the use of a hub 28. The hub 28 is substantially cylindrical and is coaxially mounted on the axle 14 such that the hub 28 receives the axle 14 coaxially along the rotational axis 20. A bearing spacer 30 is mounted between the friction drive 16 and a bearing 32 mounted in the hub 28 of the wheel 12. The bearing 32 aids in the rotation of the wheel 12 relative to the axle 14.
In order to rotate the decorative figures 18, 52, 62 of the decorative wheel apparatus 10, the friction drive 16 is mounted within a recess formed within the hub 28 of the wheel 12. The friction drive 16 provides a housing 33 that is connected to and rotates with the hub 28 of the wheel 12. A floating spring 34 is partially disposed within the housing 33 and a substantially cylindrical plate 36 mounted adjacent the housing 33. A fastener 35 connects the housing 33 to the cylindrical plate 36, but allows the cylindrical plate 36 to slide along the bearing spacer 30. The floating spring 34 biases the cylindrical plate 36 to slide along the bearing spacer 30 toward the center of the wheel 12. An O-ring 38 is partially disposed within a substantially cylindrical recess provided in the cylindrical plate 36. The floating spring 34 biases the cylindrical plate 36 against a substantially cylindrical spool 42 such that the O-ring 38 engages the cylindrical spool 42. The spool 42 is connected to a radially extending shaft 44 which may be connected to one or more of the decorative figures 18, 52, 62. The spool 42 and the shaft 44 are coaxially mounted about a rotational axis 17 that is substantially perpendicular to the rotational axis 20 of the axle 14 and the cylindrical plate 36.
To support rotation of the decorative disc 18, the decorative disc 18, in a first embodiment, is coaxially mounted to the shaft 44 about the rotational axis 17, as seen in FIGS. 1-2. A bearing 46 on each side of the decorative disc 18 is coupled to the shaft 44 to support rotation of the shaft 44 about the rotational axis 17. Each bearing 46 is housed within a bearing retainer 48 which in turn is connected to the wheel 12. The wheel 12 has a substantially circular cut-out portion 50 to allow the decorative disc 18 to rotate about the rotational axis 17 and through the wheel 12. The rotation of the decorative disc 18 in response to the rotation of the axle 14 enhances the aesthetic appearance of the wheel 12 and the vehicle.
We have described the structure associated with the rotation of one decorative disc 18, however, as seen in FIG. 1, the decorative wheel apparatus 10 of the present invention discloses the use of three decorative discs 18 in association with the wheel 12. Each decorative disc 18 has its own shaft 44 and spools 42, as noted above, but all of the decorative discs 18 share the same friction drive 16. However, the decorative wheel apparatus 10 of the present invention is not limited to three decorative discs 18, but rather, the decorative wheel apparatus 10 may comprise any number of decorative discs 18 utilized to enhance the aesthetic appearance of the wheel 12 and the vehicle.
In a second embodiment, two decorative discs 52 rotate about an axis 54 that is substantially parallel with the rotational axis 20 of the axle 14, as seen in FIGS. 3-4, as opposed to the decorative disc 18 rotating about the axis 17 substantially perpendicular to the rotational axis 20 of the axle 14, as described in the first embodiment. In order to rotate the two decorative discs 52, a second larger spool 64 is mounted on the radially extending end of a shaft 56, and the first smaller spool 42 is mounted on the opposite end of the shaft 56. The shaft 56 is rotatably supported by a pair of bearings 58 and bearing retainers 60 mounted to the wheel 12. The decorative discs 52 are rotationally mounted on each side of the wheel 12 such that the rotational axis 54 of the decorative discs 52 is substantially parallel to the rotational axis 20 of the axle 14. Each of the decorative discs 52 are rotatably supported by bearings 66 and a bearing retainer 67 which are connected to the wheel 12, and each of the decorative discs 52 have a pair of O-rings 68 partially disposed within recesses provided in the inner periphery of the decorative discs 52. The second spool 64 engages the O-rings 68 on the decorative discs 52 such that the rotation of the second spool 64 drives the decorative discs 52 about the rotational axis 54. The rotation of the decorative discs 52 enhances the aesthetic appearance of the wheel 12 and the vehicle. It should be noted that the present invention is not limited to two decorative discs 52, but rather, the present invention anticipates one or any number of decorative discs 52 in order to enhance the aesthetic appearance of the vehicle.
We have described the structure associated with the rotation of the pair of decorative discs 52, however, as seen in FIG. 3, the decorative wheel apparatus 10 of the present invention discloses the use of three pairs of decorative discs 52 in association with the wheel 12. Each pair of decorative discs 52 has its own shaft 56 and spools 42, 64, as noted above, but all of the decorative discs 52 share the same friction drive 16. However, the decorative wheel apparatus 10 of the present invention is not limited to three pairs of decorative discs 52, but rather, the decorative wheel apparatus 10 may include any number of pairs of decorative discs 52 utilized to enhance the aesthetic appearance of the vehicle.
To further enhance the aesthetic appearance of the wheel 12, the decorative figure 62 is mounted to the shaft 56 between the bearings 58 and the bearing retainers 60. The decorative figure 62 is shown having a general pine tree-shaped configuration. However, the present invention is not limited to the general pine tree-shaped configuration, but rather, any decorative configuration that is aesthetically pleasing upon the rotation thereof may be utilized. The decorative figure 62 is mounted on the shaft 56 such that the decorative figure 62 rotates with the shaft 56 about the rotational axis 17. The wheel 12 has a cut-out portion 63 corresponding to the shape of the decorative figure 62 such that the decorative figure 62 may rotate about the rotational axis 54 of the shaft 56 and through the wheel 12. The present invention is not limited to only one of the decorative figure 62 mounted to the shaft 56, but rather, the present invention anticipates that any number of decorative figure 62 may be mounted on the shaft 56. Although FIGS. 3-4 disclose the use of three decorative figure 62 on the wheel 12, the present invention is not limited to three of the decorative figure 62 being installed on the wheel 12, but rather, any number of decorative figure 62 may be installed on any number of shafts 56 mounted on the wheel 12.
In operation, the decorative wheel apparatus 10 is mounted to the wheel 12 of a vehicle, such as a motorcycle or other wheeled vehicle. As the vehicle advances, the axle 14 rotates thereby driving the friction drive 16. The housing 33 and the cylindrical plate 36 of the friction drive 16 spin with the axle 14. The O-ring 38 on the cylindrical plate 36 engages and spins the spool 42 which rotates the shaft 44 and, in turn, rotates the decorative figures 18, 52, 62. The decorative figures 18, 52, 62 may rotate about a rotational axis 17, 54 substantially perpendicular and substantially parallel, respectively, to the rotational axis 20 of the axle 14. The rotation of the decorative figures 18, 52, 62 enhances the aesthetic appearance of the wheel 12 and the vehicle associated therewith.
While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to those disclosed embodiments, but on the contrary, it is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims which scope is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures as is permitted under the law.
