Patent ID: 7213889

Claim:
Securing structure of a wheel cover, comprising: a plurality of connecting elements spaced apart around a center of an inward side of a main body of a wheel cover; each connecting element having a first gap at an inward end, and a second gap in communication with the first gap; each connecting element having a fitting hole, and a bar-shaped portion between the second gap and the fitting hole; and a plurality of first coupling pieces connected to respective ones of the connecting elements for securing the wheel cover to a wheel; a plurality of second coupling pieces, which have different dimensions from the first coupling pieces, provided for use as alternatives to the first coupling pieces; each coupling piece having: (a) a convexly curved protrusion on an outward side of a first part thereof; the convexly curved protrusion being capable of fitting into an annular groove of a wheel so as to secure the wheel cover to the wheel; (b) a stopping plate portion connected to an outward end of the first part of the coupling piece and held in the gap of a corresponding connecting element; the stopping plate portions of the first coupling pieces having a same width as the first gaps of the connecting elements; the stopping plate portions of the second coupling pieces having a same width as the second gaps of the connecting elements; (c) a fitting block portion formed on an inward side of the stopping plate portion and inserted into the fitting hole of a corresponding connecting element; (d) a recess next to the inward side of the stopping plate portion to receive the bar-shaped portion of a corresponding connecting element; (e) both a projection and a stopping block on an inward side of the first part; a fitting trench being provided between the projection and the stopping block for fitting a metallic ring therein; and (f) a pair of holding block portions formed on an outward end portion of the inward side of the first part to touch a lateral side of a corresponding connecting element; whereby a distance between the convexly curved protrusions and the main body of the wheel cover can be adjusted to suit a dimension of the wheel by means of replacing the first coupling pieces with the second coupling pieces.
