Abstract
Abstract A vehicle wheel cover formed of plastic or metal having a wire ring supported on the inboard face thereof. The ring is formed with a plurality of circumferentially spaced radially outwardly extending projections which are designed to forcibly engage an annular surface on the wheel to retain the cover thereon. The ring is supported on the cover such that the forces developed by displacing the projections radially inwardly as a result of mounting the cover on a wheel are substantially completely absorbed by the ring itself rather than being transmitted to the cover. Thus the cover itself is not subjected to any forces which tend to flex or distort it.

Total Claims: 19
Claim 1
Independent Claim
403 words
A wheel cover adapted for application to the outboard face of a vehicle wheel of the type having a radially inwardly facing annular surface concentric with the wheel axis and with which the wheel cover is adapted to frictionally engage to retain the cover on the wheel, said cover having an annular portion which, when the cover is applied to the wheel, overlies said annular surface of the wheel, a spring wire ring mounted on the inboard face of the cover concentric with said annular portion, said ring lying in a generally flat plane perpendicular to the central axis of said annular portion of the cover, said wire ring having a plurality of at least three radially outwardly extending projections thereon adapted to engage said annular surface when the cover is applied to the wheel, said projections being spaced apart circumferentially around said ring and being connected by portions of the ring extending circumferentially between the projections, the outer ends of said projections defining a circle having a diameter at least slightly greater than the diameter of said annular surface of the wheel when the ring is in the unstressed condition, said projections having generally parallel side edge portions extending generally radially of the ring in the plane thereof, said projections being relatively rigid in a radial direction and acting as rigid columns when radially inwardly directed forces are applied to the radially outer ends thereof, said circumferentially extending portions of said ring being resiliently flexible radially in the plane of the ring in response to radial displacement of said projections, a plurality of ring mounting means on the inboard face of the cover spaced apart circumferentially to correspond with the circumferential spacing of said projections, each of said mounting means having a pair of radially extending guide surfaces thereon spaced apart to engage said side edge portions of said projections with a close sliding fit for preventing relative circumferential and axial movement between the ring and the cover, said close sliding fit also preventing radial displacement of the ring as a whole relative to the cover while permitting free radial inward movement of the projections relative to the cover, said circumferentially extending portions of said ring between said projections being relatively free of the cover in a radial direction to permit flexing thereof in the plane of the ring without transmitting forces to the cover when the projections are displaced radially inwardly.
Claim 2
Dependent Claim
403 words
A wheel cover adapted for application to the outboard face of a vehicle wheel of the type having a radially inwardly facing annular surface concentric with the wheel axis and with which the wheel cover is adapted to frictionally engage to retain the cover on the wheel, said cover having an annular portion which, when the cover is applied to the wheel, overlies said annular surface of the wheel, a spring wire ring mounted on the inboard face of the cover concentric with said annular portion, said ring lying in a generally flat plane perpendicular to the central axis of said annular portion of the cover, said wire ring having a plurality of at least three radially outwardly extending projections thereon adapted to engage said annular surface when the cover is applied to the wheel, said projections being spaced apart circumferentially around said ring and being connected by portions of the ring extending circumferentially between the projections, the outer ends of said projections defining a circle having a diameter at least slightly greater than the diameter of said annular surface of the wheel when the ring is in the unstressed condition, said projections having generally parallel side edge portions extending generally radially of the ring in the plane thereof, said projections being relatively rigid in a radial direction and acting as rigid columns when radially inwardly directed forces are applied to the radially outer ends thereof, said circumferentially extending portions of said ring being resiliently flexible radially in the plane of the ring in response to radial displacement of said projections, a plurality of ring mounting means on the inboard face of the cover spaced apart circumferentially to correspond with the circumferential spacing of said projections, each of said mounting means having a pair of radially extending guide surfaces thereon spaced apart to engage said side edge portions of said projections with a close sliding fit for preventing relative circumferential and axial movement between the ring and the cover, said close sliding fit also preventing radial displacement of the ring as a whole relative to the cover while permitting free radial inward movement of the projections relative to the cover, said circumferentially extending portions of said ring between said projections being relatively free of the cover in a radial direction to permit flexing thereof in the plane of the ring without transmitting forces to the cover when the projections are displaced radially inwardly.
Claim 3
Dependent Claim
53 words
A wheel cover as called for in claim 1 wherein said ring comprises a plurality of circumferentially successive segments having radially outwardly bent opposite ends, said ends being in circumferentially abutting relation and defining at least some of said projections, said mounting means engaging and retaining said bent ends in circumferentially abutting relation.
Claim 4
Dependent Claim
27 words
A wheel cover as called for in claim 2 wherein the adjacent ends of successive segments comprise a pair of loop sections nested one within the other.
Claim 5
Dependent Claim
37 words
A wheel cover as called for in claim 3 wherein each of said projections is defined by a pair of said radially outwardly bent ends whereby the number of segments corresponds to the number of said projections.
Claim 6
Dependent Claim
18 words
A wheel cover as called for in claim 4 wherein said projections are spaced equally around said ring.
Claim 7
Dependent Claim
20 words
A wheel cover as called for in claim 5 wherein all of said segments are of substantially the same configuration.
Claim 8
Dependent Claim
27 words
A wheel cover as called for in claim 1 wherein said flexible connecting portions of said ring are radially bowed between the inner ends of said projections.
Claim 9
Dependent Claim

A wheel cover as called for in claim 7 wherein said bowed portions comprise a generally straight central section and two generally straight end sections which are inclined radially inwardly from the opposite ends of said central section to the inner end of the adjacent projections, said end sections extending generally perpendicular to the adjacent projections.
Claim 10
Dependent Claim
30 words
A wheel cover as called for in claim 8 wherein said central section has a length equal to at least about twice the length of each of said end sections.
Claim 11
Dependent Claim
42 words
A wheel cover as called for in claim 1 wherein the outer extremity of each projection defines a wheel-engaging biting edge which, when engaged with said annular surface of the wheel, tends to prevent relative rotation between the cover and the wheel.
Claim 12
Dependent Claim
