Abstract
The wheelchair wheel cover includes a cover hub, radially extending disk and an integral radially outer wall that extends axially from the disk to a cover inboard edge. The cover hub includes a bore that receives a fixed bolt. The bolt passes through a wheel bearing with an inner race and an outer race. The bolt also passes through the frame of a wheelchair and screws into a nut. When the wheel cover is non-rotating, tightening the nut forces the cover hub against an inboard washer, forces the inboard washer against the inner race and forces the inner race against the frame. If the wheel cover is to rotate a thrust bearing is provided between the head of the axle bolt and the cover hub and the inboard washer is forced toward the outer race. The disk can be flat or sculptured and protects hands and fingers.
