Abstract
Abstract A wheel and hub cap assembly wherein a cast metal wheel has a hollow hub portion housing the wheel mounting holes receiving studs to secure the wheel of a vehicle with the hub portion forming an annular groove opening radially inwardly relative to the axis of the wheel to receive a hub cap covering the opening. The hub cap has radially extending retaining elements complementary to the groove to support the hub cap relative to the wheel and limit axial inward and outward movement with the retaining elements being substantially the only contact between the wheel and hub cap.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
253 words
A wheel and hub cap assembly comprising: a cast metal wheel including a tire mounting rim, a hub portion including wheel mounting holes uniformly spaced on a circle coaxial with said wheel, a generally disc-shaped spider portion extending between said tire mounting rim and said hub portion and formed integrally therewith, said hub portion forming an axially extending recess with a substantially cylindrical wall radially outwardly of said bolt circle and forming an access opening adjacent an outboard edge of said wheel, a continuous annular groove formed in said wall and opening radially inwardly relative to the axis of said wheel, said groove being disposed axially outwardly of said wheel mounting opening and axially inwardly of said access opening, a hub cap for closing said access opening, said hub cap having circumferentially spaced and radially extending resilient retaining elements disposed in said groove, a rigid guide surface between said groove and the outer end of said recess, said guide surface being adapted to engage said retaining elements for gradually deflecting the latter radially inwardly upon axial movement of said cap relative to said wheel to permit displacement of said retaining elements radially inwardly and entry into said groove upon attachment of said hub cap to said wheel, said retaining elements simultaneously engaging the axially inner and outer walls of said groove to limit axial inward and outward movement relative to said wheel and maintaining the remainder of said hub cap in close spaced relation to said access opening to substantially close said recess.
Claim 2
Dependent Claim
253 words

Claim 3
Dependent Claim
21 words
The combination of claim 1, wherein said guide surface has an axial length greater than the axial dimension of said retainers.
Claim 4
Dependent Claim
32 words
The combination of claim 2, wherein said guide surface converges radially inwardly as it approaches said annular groove at an angle with the axis of said wheel no greater than twenty-five degrees.
Claim 5
Dependent Claim
41 words
The combination of claim 3, wherein said groove has an angled guide wall formed at an axially outer edge of said groove and disposed at an angle with the axis of said wheel greater than the angle of said guide surface.
Claim 6
Dependent Claim
17 words
The combination of claim 4, wherein said angle of said guide wall is at least thirty-five degrees.
Claim 7
Dependent Claim
34 words
The combination of claim 1, wherein said annular groove has an annular wall at an axially inward edge of said groove to engage said retainer and limit axial inward movement of said hub cap.
Claim 8
Dependent Claim
26 words
The combination of claim 6, wherein said annular wall has a radial dimension greater than the depth of said annular groove adjacent to said guide wall.
