Abstract
Abstract A wheel cover with a plurality of axially extending resilient prongs the free ends of which extend through prong receiving holes in the mounting bolt circle area of a disk of a vehicle wheel. The prongs have a cam surface adjacent the free edge thereof which engages the inner edge of the prong receiving holes to abut the free ends of the prongs with the mounting surface of a hub on which the disk is secured to firmly and tightly retain the wheel cover on the wheel.

The hub cap of claim 1 wherein each of said prongs is resiliently flexible and generally radially displaced from its unflexed position when its free end is inserted into its associated prong receiving hole and snaps back toward its unflexed position to urge its associated cam means into engagement with the inner margin of the associated prong receiving hole when its free end passes through the associated prong receiving hole.
Claim 7
Dependent Claim
16 words
The hub cap of claim 5 wherein said prongs are homogeneously integral with said cap body.
Claim 8
Dependent Claim
65 words
The hub cap of claim 1 wherein each of said prongs is resiliently flexible and said cam means on said prongs comprises a rib extending generally transversely around at least a portion of the outer periphery of its associated prong and having a generally V-shaped cross section with its apex terminating radially outwardly of the outer periphery of an adjacent portion of its associated prong.
Claim 9
Dependent Claim
29 words
The hub cap of claim 7 wherein said cap body, prongs and cam means on said prongs are homogeneously integral and made in one piece of a plastic material.
Claim 10
Dependent Claim
26 words

Claim 11
Dependent Claim
245 words
In combination, a vehicle wheel having a rim and a disk fixed thereto, a plurality of prong receiving holes disposed in the mounting hole circle area of said disk and each arranged to provide a space having a predetermined axial dimension between the inner margin of each prong receiving hole and the surface on which the disk bears when mounted on a vehicle, a removable hub cap body constructed and arranged to overlie both said prong receiving holes and mounting holes in said disk and to be removable from said disk, a plurality of prongs carried by said body and extending generally axially from one face thereof with the free end of each of said prongs constructed and arranged to pass through one of said prong receiving holes, and cam means on each of said prongs adjacent the free end thereof constructed and arranged to engage said inner margin of one of said prong receiving holes and urge the free end of its associated prong into firm engagement with the surface on which the disk bears when mounted on a vehicle, whereby said removable hub cap body is releasably secured and tightly retained on said vehicle wheel when said prongs are inserted in said prong receiving holes with their associated cam means firmly engaging the inner margins of said prong receiving holes and urging the free ends of said prongs into engagement with the surface on which the disk bears when mounted on a vehicle.
