DETAILED DESCRIPTION OF INVENTION
Referring to the drawings in detail wherein like elements are indicated by like numerals, there is shown in FIGS. 1–4 a first embodiment 1 of the invention and in FIGS. 5–8 a second embodiment 2 of the invention, both embodiments constructed according to the principles of the present invention. Each toy wheel 1, 2 is comprised of a rim assembly 10, 20 and a hub assembly 30, 40. Both toy wheel embodiments 1, 2 are adapted to having a tire 3 fitted over the rim assemblies 10, 20.
Referring more particularly to FIGS. 1–4, the first invention embodiment 1 is based upon the use of ball bearings 4. The toy wheel rim assembly 10 is comprised of two annular rings 11, each a mirror image of the other. The rings 11 each have a substantial and round central opening 12, an outer perimeter 13, an inner perimeter 14 defining the central opening 12, a flat interior side 15 facing the other ring, and an outer side 16. Each ring outer side 16 has a curved flange 17 extending out from the inner perimeter 14 and extending a predetermined distance toward a ring central axis. Each ring 11 has three threaded apertures 18 equidistantly formed therein and extending partly above the outer perimeter 13, each said aperture 18 extending from the outer side 16 through the ring 11 and out through the interior side 15, each said aperture 18 having a central axis transverse to a ring radial axis. The rings 11 are positioned against each other with the apertures 18 of one ring aligned with the apertures 18 of the other ring. The rim assembly 10 includes three threaded fasteners 19, each adapted to threadingly engage two adjacent apertures 18 thereby fixedly attaching one ring to the other. A tire 3 may be fitted over the rim assembly joined ring outer perimeters 13.
The toy wheel hub assembly 30 of the first invention embodiment is comprised of two generally flat, round disks 31, each a mirror image of the other. The disks 31 each have an outer perimeter 32, a flat interior side 33 facing the other disk, and an outer side 34. Each disk 31 has three threaded apertures 35 equidistantly formed about the disks, each said aperture 35 extending from the outer side 34 through the disk 31 and out through the interior side 33, each said aperture 35 having a central axis transverse to a disk radial axis. The disks 31 are positioned against each other with the apertures 35 of one disk aligned with the apertures 35 of the other disk. The hub assembly 30 includes three threaded fasteners 36, each adapted to threadingly engage two adjacent apertures 35 thereby fixedly attaching one disk to the other. Each disk 31 has a substantial off-center and round opening 37 adjacent the outer perimeter 32. The disk openings 37 for each disk 31 match and are aligned when the disks 31 are connected to each other. The hub assembly disk opening 37 is adapted to receive and hold a cylindrical weight 38. Each disk outer perimeter 32 has an eight indentations 39 formed therein, said indentations being positioned equidistantly about the disk outer perimeter 32. The outer perimeter indentations 39 of one disk 31 are aligned with the outer perimeter indentations of the other disk when the disks are joined together.
A ball bearing 4 is placed into each hub assembly indentation 39. The hub assembly 30 is positioned within the rim assembly central opening 12. The rim assembly central opening curved flanges 17 hold the hub assembly 30 within the rim assembly central opening 12 and trap the ball bearings 4. The ball bearings 4 rotate within the hub assembly indentations 39 and against the inner perimeters 14 of the rim assembly rings 11 with little friction. The hub assembly weight 38 keeps the hub assembly 30 at the same orientation at all times regardless of rim assembly 10 speed or angle of motion.
Referring more particularly to FIGS. 5–8, the second invention embodiment 2 is based upon the use of roller bearings 5. The toy wheel rim assembly 20 is comprised of two annular outer rings 21, each a mirror image of the other. The outer rings 21 each have a substantial and round central opening 22, an outer perimeter 23, an inner perimeter 24 defining the central opening 22, a flat interior side 25 facing the other outer ring, and an outer side 26. Each outer ring inner side 26 has a eight slots 27 formed therein radially extending from the inner perimeter 24 a predetermined distance toward the outer perimeter 23, said slots 27 being positioned equidistantly about the outer ring inner side 26. The slots 27 of one outer ring 21 are aligned with the slots of the other outer ring when the outer rings are joined together. Each outer ring 21 has three threaded apertures 28 equidistantly formed therein and extending partly above the outer perimeter 23, each said aperture 28 extending from the outer side 26 through the outer ring 21 and out through the interior side 25, each said aperture 28 having a central axis transverse to an outer ring radial axis. The outer rings 21 are positioned against each other with the apertures 28 of one outer ring aligned with the apertures 28 of the other outer ring. The rim assembly 20 includes three threaded fasteners 29, each adapted to threadingly engage two adjacent apertures 28 thereby fixedly attaching one outer ring to the other. A tire 3 may be fitted over the rim assembly joined outer ring outer perimeters 23.
The toy wheel hub assembly 40 of the second invention embodiment is comprised of two inner rings 41, each a mirror image of the other. Each inner ring 41 has an outer perimeter 42, an inner perimeter 43, an interior side 44 facing the other inner ring, and an outer side 45. Each interior side 44 has an annular groove 46 formed therein adjacent the outer perimeter 42. Each inner ring 41 has three threaded aperture rings 47 equidistantly formed about the rings attached to the inner ring inner perimeter 43, each said aperture 47 having a central axis transverse to an inner ring radial axis. The inner rings 41 are positioned against each other with the apertures 47 of one inner ring aligned with the apertures 47 of the other inner ring. The hub assembly 40 includes three threaded fasteners 48, each adapted to threadingly engage two adjacent apertures 47 thereby fixedly attaching one inner ring to the other. Each inner ring 41 has a substantial holding ring 49 off-center and attached to a portion of the inner ring inner perimeter 43. The holding rings 49 for each inner ring 41 match and are aligned when the inner rings 41 are connected to each other. The hub assembly holding rings 49 are adapted to receive and hold a cylindrical weight 38.
The hub assembly 40 is positioned within the rim assembly central opening 22. The hub assembly 40 is further comprised of eight roller bearings 5 each comprised of a roller disk 6 and a central shaft 7 extending centrally from each side of the roller disk. The roller disks 6 are placed into the hub assembly annular groove 46, wherein each roller bearing central shaft 7 engages a set of rim assembly slots 27. The roller bearings 5 rotate within the hub assembly annular groove 46 and are held in place by the roller bearing shaft 7 engagement with the rim assembly slots 27. The hub assembly weight 38 keeps the hub assembly 40 at the same orientation at all times regardless of rim assembly 20 speed or angle of motion.
It is understood that the above-described embodiment is merely illustrative of the application. Other embodiments may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof. For example more or less ball bearings and/or roller bearings may be used. More or less threaded apertures may be used for joining rings and disks. In the hub assemblies more than one opening and/or holding ring may be used, along with additional weights. In addition to weights, decorative displays may be used. Tires of various styles may be used, e.g., all-terrain, smooth, etc. The rim assemblies may also be stylized with commercial themes, fantasy themes, robotic, wings, etc. Several wheels may be joined together or to a common structure.
