DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
The “flipper” vehicle wheel accessory itself, including hub 9, may connect to a prior art coupling device on a vehicle rim which will allow the accessory to spin freely of the traditional rim behind it as mentioned previously. Alternatively, it may be directly rigidly connected to a conventional vehicle hub somewhat like a spare tire assembly is bolted to an automobile.
The overall configuration of a “flipper” vehicle wheel accessory is indicated in FIG. 1B. A hub 9 of the accessory supports a plurality of decorative blades 1 that have various designs or surface textures, shapes or finished styles upon front and back surfaces such as satin surfaces, grooved surfaces or other geometric designs that can even have various colors. Each blade 1 is coupled to hub 9 in a manner to enable the blade to turn over, or be flipped over 180 degrees, thus permitting the design on the blade back to be now visible in place of the previously visible design on the blade before being turned over 180 degrees. The blades 1 of course rotate along with the hub somewhat in the manner of a windmill. Optionally, additional blades 14 could be affixed to rim 16B of FIG. 1A schematically illustrating a conventional automotive wheel rim for having a tire (not shown) mounted thereon. This further enhances the appearance of the wheel assembly.
The main components described are preferably utilized to assemble the wheel assembly. There is only one hub, and there are as many blades/springs/spokes as determined necessary by the design desired; five being typical as shown in FIG. 1.
A single vane or blade 1 shown in FIGS. 2 and 3 comprises the wide, flat portions of the wheel accessory which may be rotated 180 degrees as mentioned above to change designs. The blade itself is fashioned with an upper internal cavity 2 and a lower internal cavity 3. The cavities contain a cylindrical spoke shaft 4. When the blade is in a closed or retracted position, shown in FIG. 2, the lower cavity 3 will encompass a hinge 10 where the spoke shaft connects to the hub 9 at portion 11A, e.g. by welding. See also FIG. 4 further illustrating the hinge and blade.
As shown in FIG. 2, the blade's rectangular base 8 fits into a rectangular receptacle 11 affixed to central hub 9, e.g. by welding, which receptacle 11 contains the hinge 10 to which the spoke shaft 4 connects as shown in FIG. 2. The two external, visible, large surfaces of blade 1, on opposite sides of the blade, would typically carry two different designs that can consist of different colors, finishes, metals, and other possible ornamental designs. These designs are indicated by wavy lines 1A in FIG. 1B. Alternatively, commercially available ornamental stickers bearing colorful ornamental designs may be adhered to opposite sides of the blade surfaces. For example the blades could have all green designs for St. Patrick's Day or the blades could be colored red, white and blue for the Fourth of July.
As shown in FIGS. 2 and 3, spring 6 can be a standard helical spring which preferably is stiff enough to hold the blade to the hub even while the wheel assembly is rotating or spinning, but compliant enough to be contracted or compressed while a person or device pulls the blade 1 outward in a radial direction away from the hub. The spring 6 fits around cylindrical spoke shaft 4 just below its cylindrical spoke head 5. The spring rests upon an internal lip 7 in the blade. When the blade is pulled outward radially, the spring contracts and is compressed between the spoke head, and the internal lip 7 inside of the blade, as shown in FIG. 3, mechanically biasing the blade inwardly toward hub 9 and hub portion 9A as shown in FIG. 4.
As mentioned above, the accessory enables the user to switch which design is visible on its flipper blades. To do this, the user pulls up on the blade to a position above the hub's rectangular receptacle 11 and above the hinge 10 between the spoke and hub portion 9A as shown in FIG. 4. This also contracts the spring putting it in compression. Once the hinge is uncovered, the user can bend the blade towards him or her about its hinge at an angle of typically 30-45 degrees as shown in FIG. 4, and then rotate the blade 180 degrees about its longitudinal axis 4a extending down the middle of the spoke shaft. In doing this, the user changes the visible view. If Design A was on the front visible side of the blade before the user turned it, and Design B was on the back side, rotating the blade 180 degrees would place Design B on the front, visible side, and Design A on the back, hidden side of the blade.
After rotating the blade, the user tips the blade back into its position shown in FIG. 3 about its hinge 10. Then the user allows the blade to slide into the hub's rectangular receptacles as shown in FIG. 2 by virtue of the expansion and biasing effect of spring 6 and be effectively in place once again upon the hub but with the alternate design visible. Thus, spring 6 aids in maintaining seating of lower blade portion 8 within receptacle 11. If the lower blade portion is shaped as a rectangular or square or as another shape e.g. as a hexagon etc., then the container 11 will be similarly shaped as a rectangle or square or hexagon.
The blades and other components may be made of metal or injection molded plastic.
The wheel accessory can also be utilized in vehicles other than automotive vehicles such as bicycles, carts or a wheelchair. For example if an embodiment of the invention were to be utilized on a slow speed vehicle such as a toy vehicle or a wheelchair, the hinge providing outward tipping of the blade as indicated in FIGS. 4 and 5 could be eliminated and the blade could be flipped over 180 degrees in the outward position shown in FIG. 3 and returned to the inward position shown in FIG. 2.
The wheel accessory can be directly affixed to a vehicle wheel or can be coupled to an intermediate member such as a bearing assembly allowing the wheel accessory to rotate independently relative to a corresponding wheel as disclosed in Fowlkes U.S. Pat. No. 6,554,370.
Known anti-theft devices known in the art may be utilized; e.g. D'Angelo U.S. Pat. No. 4,061,400.
