Claim:
A method for interlocking a wheel-rim cover to a wheel-rim body, comprising the steps of: providing a wheel-rim cover body; providing a plurality of engaging seats disposed along a peripheral edge of said wheel-rim cover body, each of said engaging seats including an engaging slot formed therein with at least one inner wall thereof having an inwardly inclined surface, each of said engaging seats further having a pair of ridge portions respectively extending from opposing sides thereof; providing a plurality of interlocking blocks respectively pivotally coupled to said plurality of engaging seats, each of said interlocking blocks having inside and outside edges and a pair of pivotal contact portions disposed on opposing sides thereof respectively engaged with said pair of ridge portions of a corresponding one of said engaging seats for displaceably securing said interlocking block to said corresponding engaging seat, said inside edge being disposed within said engaging slot and defining a displaceable pivotal axis of said interlocking block; disposing said wheel-rim cover body on the wheel-rim body to thereby abut said outside edges of said plurality of interlocking blocks against a surface of an engaging groove of the wheel-rim body; and displacing said wheel-rim cover body toward a hub of the wheel-rim body to displace said outside edges of said plurality of interlocking blocks along the surface of the engaging groove toward an outer edge thereof and thereby displace said inside edge of each said interlocking block along said inwardly inclined surface of a corresponding engaging slot to frictionally engage said interlocking block between said inclined surface of said engaging slot and the surface of the engaging groove of the wheel-rim body.
