DETAILED DESCRIPTION OF THE INVENTION

(5) The universal wheel, according to this invention, is generally mounted on automobiles which have a variety of lug patterns. As shown in the drawings, wheel disc 1 extends outwardly from attachment hub 2 which is unitary and disposed at the center of the wheel. Hub 2 includes outer circular flange 3 integrally joined to the outer edge of cylinder 4 and, on the inner edge of cylinder 4, aperture plate 5 is integrally affixed and extends inwardly therefrom. Multiple lug receiving apertures 6 are formed in aperture plate 5 and are configured to receive a variety of vehicle wheel lugs in varying patterns, for example, 4, 5, 6 and 8 universal lug bolt patterns. A central bore is formed in aperture plate 5 to receive the automobile axle, as is well known.

(6) According to a feature of this invention, a securing ring, generally indicated by the numeral 7 in FIG. 3, is spaced inwardly from flange 3 and extends around the outer periphery of cylinder 4 of hub 2. Ring 7 is secured to hub 2 by means fasteners in the form of four screws or bolts 8 which extend into corresponding threaded apertures formed in cylinder 4. Screws or bolts 8 are flexible to provide stress dampening to counter normal vibration encountered in the movement of the automobile and especially the components of the vehicle wheel.

(7) According to this invention and as best shown in FIG. 4, hub 2 comprises bearing surface 9a which extends around the outer periphery of cylinder 4 between flange 3 and securing ring 7. Also, the inner surface of wheel disc 1 is curved at 9b and is disposed around bearing surface 9a in an abutting manner to allow surface 9b to rotate around surface 9a.

(8) With particular reference to FIG. 3, the details of securing ring 7 are shown wherein ring 7 is of a circular configuration and includes circular channel 10, the curvature of which provides added rigidity and strength to ring 7 and ensures that hub 2 is correctly centered on the vehicle. Wedges 11 are integrally joined to securing ring 7 the underside of which conform to the contours of the surface of securing ring 7 and channel 10 and provide strength at the attachment point between securing ring 7 and hub 2. Apertures 12 extend through each wedge 11 and flexible bolts 8 extend through apertures 12 and into corresponding threaded apertures formed in cylinder 4 of hub 2.

(9) Wheel disc 1 is provided with tire 13 extending around the periphery thereof, as is well known.

(10) As shown in FIG. 1, a nonspinning universal wheel is assembled by securing wheel disc 1, tire 13 and attachment hub 4 by means of multiple bolts 14 which are screwed into wedge nuts 15 which are disposed in corresponding cavities formed on the inner side of wheel disc 1. The cavities are best shown in FIG. 2. Wedge nuts 15 are configured of a dimension one millimeter larger than the inside dimension of the respective wheel disc cavity. By this means, wedge nuts 15 are forced into each cavity and are frictionally maintained within the cavities to prevent them from inadvertently falling out when not interconnected to the bolts.

(11) The nonspinning universal wheel is mounted on an automobile whereby the wheel lugs extend through apertures 6 and the wheel is secured in place thereto by conventional lug nuts. By this means, the universal wheel is securely affixed to the automobile in a conventional manner and in situations where a nonspinning tire is applicable.

(12) In order to convert a nonspinning universal wheel to a spinner-roller wheel. As shown in FIG. 1, bolts 14, from the front side of the vehicle wheel, are loosened from corresponding wedge nuts 15 and removed. Ring 7 is then slipped over the inner free end of cylinder 4 to a position flush with the inner surface of wheel disc 1 and attached thereto by means of bolts 8 which extend through apertures 12 disposed in wedges 11 and are affixed to corresponding threaded apertures disposed in cylinder 4. By this means, wheel disc 1 and attached tire 13 are freely rotatable around hub 2. The bearing surface 9a and sliding surface 9b are appropriately lubricated to enhance rotation of the wheel. To return the wheel to a normal rolling wheel, it is simply necessary to reinstall bolts 14 and interconnect them with corresponding wedge nuts 15 which are secured in cavities on the inner side of the wheel. Once installed, ring 7 stays in place whether the wheel is configured to spin or not.

(13) Therefore, by this invention, a universal wheel provides a unique mobility solution for standard or electric cars in situations where the brakes freeze or there is no power to the vehicle wheels. The is hub bolted onto the automobile in the conventional manner and then the car can be pushed or pulled around the repair shop or maneuvered onto a tow truck. The universal spinner wheel is easily converted into a conventional wheel whereby the bolts securing the flange to the steel center of the wheel are reinstalled.
