Ornamental wheel cover retention system

摘要

An ornamental wheel cover integrally retained on the lug nuts of a vehicle wheel that provides positive positioning of the cover to the lug nuts. The lug nuts preferably have a flange that defines an upper shoulder. The cover is provided with a number of elongated tubular extensions axially projecting from the cover that are each partially slotted to provide a plurality of cantilevered fingers. Each finger has an undercut groove that has a shoulder which positively positions the cover to the upper shoulder of the lug nuts of the wheel. Below the undercut groove is a bulbous portion that contacts the lug nut below the flange. When the cover is attached to the wheel, the elongated tubular extensions are aligned with the lug nuts and the cover is moved axially inwardly of the wheel so that the cantilevered fingers separate slightly as the bulbous portions pass over the flange of the lug nut. The shoulder of the undercut groove engages the upper shoulder of the lug nut flange, thereby providing a positive axial location of the cover to the wheel and eliminating the effects of misalignment of components due to tolerance stack ups. The bulbous portion passes over the flange of the lug nut and engages the underside of the flange, thereby retaining the cover on the lug nut.
