Abstract
A demountable wheel assembly for a vehicle which comprises an axle-retained wheel hub and a wheel, on which a tire is mounted, which are quickly releasably connectable to, or separable from each other, even by the weak, the aged, and the handicapped. Guide pins on the wheel hub align the tire mounted-wheel, while exposed permanent magnets partially embedded in the wheel hub draw and hold the wheel, thereby freeing the hands. Headless bolts are driven by a brace-shaped driver through threaded bolt nuts that are partially embedded in the wheel; through threaded, tapered extensions behind the nuts; and into threaded, tapered cavities in the wheel hub. Overtightening of the bolts is prevented by the short-span of the bolt driver.
Claims6
A demountable wheel assembly, comprising:
- a. a wheel hub;
- b. a wheel configurated and dimensioned to fit over and to complement with said wheel hub, with said wheel fitted over, complementing, and abutting with said wheel hub;
- c. and, means for releasably connecting said wheel to said wheel hub, whereby said wheel is releasably connected to said wheel hub, and wherein said means includes:
- (1) a plurality of tapered and threaded cavities in said wheel hub;
- (2) a plurality of threaded nuts affixed to said wheel, with one nut for each one of said plurality of threaded cavities in said wheel hub, wherein each said nut is partially embedded in said wheel, and wherein each said nut has affixed thereto an extension which is tapered and threaded complementarily to a corresponding cavity of said plurality of tapered and threaded cavities in said wheel hub, and wherein each said nut and its extension are in alignment with their said corresponding cavity;
- (3) and, a plurality of headless bolts, with each bolt having a first slotted end and a second tapered and threaded end, and with one bolt for each one of said plurality of threaded nuts and its corresponding cavity, wherein said threaded second end of each said bolt has threads complementary to said threads of its corresponding threaded nut, threaded nut extension, and threaded cavity, and wherein each said bolt is threadly engaged with its corresponding threaded nut, threaded nut extension, and threaded cavity.
