In another embodiment, deformable tab portions are provided to assist the mechanical interlock connection. The retention band also includes suitable wheel engaging retention members and may also be provided with integrally formed remotely actuated secondary retention portions. A method of assembly is also disclosed.
Description

BACKGROUND AND SUMMARY OF THE INVENTION
The present invention relates generally to wheel trim retention systems (including assembly methods) and more particularly to retention systems particularly designed for use with polymeric composition trim members.
Polymeric compositions are particularly desirable for use in fabricating wheel trim because of their ability to be easily and quickly molded into almost any shape or design, they allow fabrication of relatively lightweight wheel trim and they are not subject to corrosion. However, because such materials may not perform well when subjected to continuous stress such as may be exerted thereon by many types of conventional retention systems, use of these materials has not been as widely accepted as might be expected given the various advantages of such materials for this application.
A number of retention systems have been designed for use with polymeric composition wheel trim which utilize either a retention band or separate retention clips having a number of projections thereon which bitingly engage a portion of the trim member such as the inner or outer surfaces of a flange portion. However, the use of a biting engagement results in a localized stress being exerted on the trim member. This stress may result in cracking or otherwise damaging the wheel trim over a period of time or when the wheel trim is subjected to low temperature extremes.
While numerous attempts have been made to design a retention system particularly suited for use with polymeric composition wheel trim providing retention means in the form of an annular band or separate clips which do not subject the trim material to high localized stresses, most of these systems require either assembly of a number of separate components or performing additional assembly operations thereon to secure the retention means to the trim member. For example, in one form the retention means is secured to the wheel trim by rolling or otherwise forming a metal strip, which may be either a separate piece or an integral part of a retention band, over the outer peripheral edge of the trim ring. In another form, a number of pins are provided on the trim member which are received within openings in the retention band and then heat staked or otherwise deformed so as to provide an enlarged head thereon. While some of these systems may offer satisfactory performance, the need to fabricate and assemble numerous parts or perform additional operations on the wheel trim results in increased manufacturing costs.
The present invention provides a wheel trim having a retention system which overcomes these disadvantages by eliminating the need to perform additional assembly or manufacturing operations in connection with the attachment of the retention system to the wheel trim and yet also provides a retention system which substantially reduces the stresses to which the wheel trim may be subjected to. Additionally, the retention system of the present invention is designed to be assembled and secured to the trim ring as a single unit thereby assisting in reducing manufacturing costs associated therewith.
The retention system of the present invention includes a wheel trim which may be fabricated from a polymeric composition and which includes means defining a generally axially inwardly extending radially outwardly facing flange portion. An annular retention band is also provided which is designed so as to enable it to be easily and economically manufactured in strip form and which is designed to cooperate and form a mechanical interlock with the flange portion of the trim member so as to retain the retention band and trim member in assembled relationship. Because of the nature of the mechanical interlock, the retention band does not need to tightly engage the flange portion and thus the problems associated with subjecting polymeric materials to continuous stress are substantially eliminated. Additionally, because the retention band is of a design which enables it to be easily and conveniently manufactured in strip form such as by rolling or the like and because it may be directly attached to the trim member without the need to manufacture and separately attach additional screws or other means to secure the retention band to the trim member, the present retention system is very economical in terms of both labor and time to manufacture. Thus, the present invention provides a secure reliable retention system which allows the advantages offered through use of polymeric composition trim members to be obtained both economically and efficiently.
Additional advantages and features of the present invention will become apparent from the subsequent description and the appended claims taken in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings and in particular to FIGS. 1 and 2, there is shown a wheel trim indicated generally at 20 having a retention system for securing the wheel trim in overlying relationship to the axially outwardly facing surface of a vehicle wheel and which includes a trim member 22 and a retention band 24 secured thereto.
As shown, trim member 22 is fabricated from a suitable polymeric composition material and includes a generally circular shaped outer portion 26, the outer surface of which may be contoured and finished so as to provide an aesthetically pleasing appearance complementing the vehicle to which it is applied. The axially inwardly facing surface has a generally axially inwardly extending annular flange portion 28 which includes a radially outwardly opening groove 30 adjacent the axially inner edge 32 thereof. As best seen with reference to FIG. 1, the axially inner wall portion 34 of the flange portion 28 overlying groove 30 is omitted at several discrete circumferentially elongated locations 36 around the periphery of the flange portion 28 so as to afford access to groove 30 in an axial direction at these locations. An additional generally axially inwardly extending retaining flange member 38 is integrally formed with trim member 22 at each of these locations being positioned radially outwardly of and immediately adjacent flange portion 28 so as to overlie the radially outwardly facing opening of groove 30. Retaining flange 38 extends circumferentially a relatively short distance and is positioned generally centrally with respect to circumferentially elongated locations 36 where inner wall portion 34 has been omitted. Preferably four such locations 36 are provided equally spaced around trim 22 and each having a discrete retaining flange 38 associated therewith.
A plurality of integrally formed flanges 40 are also provided on the trim member 22 being integrally formed therewith and extending generally radially outwardly from the axial outer surface of the flange portion 28. Radially extending flanges 40 are each substantially shorter in an axial direction than flange 28 and define an axially inwardly facing locating shoulder 42 adapted to axially position wheel trim 20 relative to a vehicle wheel. Preferably, one of these plurality of shoulders will be positioned approximately midway between the circumferentially opposite ends of each of retaining flanges 38 and will operate to stiffen and resist radially outward deformation thereof.
Retention band 24 comprises an elongated member of a length sufficient to enable it to extend completely around the axially outer periphery of flange portion 28 of trim member 22. Retention band 24 has an irregular shape in transverse cross-section generally as shown including an axially outer edge portion 44 which is rolled or otherwise folded radially inwardly so as to form a substantially continuous generally circularly shaped annular bead 46. The axially inner edge 48 of retention band 24 is also folded radially inwardly as well. A pair of generally radially extending substantially planar surface portions 50 and 52 are provided between the edge portions 44 and 48, the axially inner surface portion 50 being slightly radially offset from axially outer surface portion 52. As best seen with reference to FIG. 2, this radial offset is selected so as to accommodate retaining flange 38 and to thereby place the radially outer surfaces of the retaining flange 38 and the axially inner planar surface 50 in substantially coplanar relationship. A plurality of retention clips 54 are secured to the axially inner surface portion 50 of the retention band, being positioned in circumferentially spaced relationship to each other. Retention clips 54 are adapted to engage a generally radially inwardly facing surface portion of a flanged vehicle wheel so as to retain the wheel trim in position thereon. While any suitable retention clips may be utilized, retention clips 54 as illustrated are substantially identical to those disclosed in U.S. Pat. No. 4,131,322 entitled "Wheel Trim Retention" which is assigned to the same assignee as the present application the disclosure of which is hereby incorporated by reference.
In order to assemble retention band 24 to the trim member 22, the bead portion 46 of a suitable length of retention band stock with retention clips 54 secured thereto is fitted into groove 30 provided on the axially inwardly extending flange portion. As is apparent, the axially inner wall portion 34 of the flange portion 28 is omitted adjacent each of the retaining flanges 38 so as to enable the bead portion 46 to be axially fitted into groove 30 in these areas. Once bead 46 has been fully inserted into groove 30, the opposite ends of the retention band 24 may then be secured in a manner as set forth below. Once the ends of retention band 24 have been secured together, the engagement between the bead 46 and groove 30 will cooperate to provide a mechanical interference therebetween which will sufficiently restrict relative movement so as to retain the retention band 24 and trim member 22 in assembled relationship. The retaining flanges 38 also assist in retaining bead 46 in engagement with groove 30 particularly during temperature extremes which may cause substantial dimensional changes in either retention band 24, trim member 22 or both.
This arrangement for securing a retention band is particularly well suited for use with polymeric composition trim members as bead 46 formed in the retention band 24 does not need to tightly engage groove 30 but rather can be somewhat loosely fitted therein so as to avoid stressing the polymeric material. Thus, the dimensional and structural relationship between the bead provided on the retention band and the groove formed in the trim member cooperate to provide a strong positive mechanical interlock therebetween thereby retaining the trim member and retention band in assembled relationship.
Referring now to FIGS. 3 through 6, another embodiment of the present invention is shown being indicated generally at 56 and comprising a trim member 58 having a retention band 60 secured thereto.
In this embodiment, trim member 58 is also preferably fabricated from a polymeric composition and has a generally axially inwardly extending annular flange portion 62 integrally formed therewith being spaced radially inwardly slightly from the peripheral edge 64 thereof. A plurality of circumferentially extending slots 66 are provided along flange portion 62 adjacent the axially inner edge 68 thereof which extend radially therethrough. Suitable radially outwardly extending axially inwardly facing locating shoulders may also be provided on the trim member similar to those illustrated in connection with the embodiment of FIGS. 1 and 2.
Retention band 60 is similar to the retention band of FIGS. 1 and 2, however, in this embodiment the axially outer edge 70 is provided with a plurality of discrete spaced circumferentially and generally radially inwardly extending tab portions 72. Tab portions 72 are suitably positioned and dimensioned so as to be received with each of the plurality of slots 66 provided on flange portion 62.
As best seen with reference to FIGS. 3 and 5, a number of tab portions 72 have an embossed portion 74 centrally disposed therealong. Embossed portion 74 projects through slot 66 and operates to insure a relatively snug fit therein thereby preventing relative axial play or movement between the retention band 60 and trim member 58 which could result in annoying noise when wheel trim 56 is installed on a vehicle. Additionally, a deformable tab 76 is also provided which may be bent axially outwardly so as to engage the radially inner surface 78 of flange portion 62 and thereby assist in retaining retention band 60 in assembled relationship with trim member 58.
Retention band 60 will preferably be fabricated in elongated strips of suitable length which may then be wrapped around flange portion 62 of the trim member 58 and thereafter the opposite ends secured together. The provision of a plurality of discontinuous mating slots 66 and tab portions 72 around the periphery of trim member 58 and retention band 60 will also operate to prevent relative rotation therebetween.
Another embodiment of the present invention is illustrated and will be described with reference to FIGS. 6 and 7 being indicated generally at 80. In this embodiment, a trim member 82 is provided which is generally similar to that of trim member 22 of FIGS. 1 and 2 and includes a generally axially inwardly extending flange portion 84 which is integrally formed with trim member 82 and positioned radially inwardly from the peripheral edge 87 thereof. Flange portion 84 is also provided with a substantially continuous radially outwardly opening annular groove 88 of a generally "U" shape in cross-section. An axial locating shoulder 92 is also incorporated in the design of trim 82 extending radially outwardly from flange portion 84 and is engageable with a portion of the vehicle wheel so as to axially position the trim member with respect thereto. A plurality of reinforcing ribs 90 extend between shoulder 92 and flange portion 84 and operate to reinforce and stiffen both flange portion 84 and shoulder 92.
A retention band 94 is also provided which is similar to that illustrated in and described with reference to FIGS. 1 and 2 including a beaded axially outer edge 96 and a radially inwardly folded inner edge 98. However, in this embodiment the retention band has a single axially extending generally planar surface 100 extending between the axially inner and outer edges 98 and 96 respectively. A plurality of retention clips 102 substantially identical to retention clips 54 secured to retention band 24 are also secured to retention band 94 in substantially equally circumferentially spaced relationship.
As best seen with reference to FIG. 8, retention band 100 also has a plurality of radially outwardly extending protrusions 104 integrally formed thereon adjacent the axially inner edge 98 and positioned approximately midway between each of the retention clips 102. As retention clips 102 are moved into engagement with the vehicle wheel, the retention forces transmitted to retention band 94 cause it to distort from a true circular shape thereby moving portions of the retention band 94 located between the retention clips 102 radially outwardly. This distortion causes protrusions 104 to move into engagement with a portion of the vehicle wheel so as to provide a secondary frictional retention force as well as limiting further distortion of retention band 94 and thereby increasing the force of engagement of the retention clips 102 with the vehicle wheel. Alternatively, rather than discrete protrusions 104 the secondary retention means may be in the form of a continuous annular bead 106 along the axially inner edge 108 such as is formed on the retention 110 illustrated in FIG. 9. This primary-secondary retention arrangement is disclosed more fully in U.S. Pat. No. 4,131,322 entitled "Wheel Trim Retention" and assigned to the same assignee as the present invention.
It should be noted that while only the embodiment of FIGS. 6 and 7 has been illustrated as including this secondary retention system, either embodiment thereof may easily be provided on any of the other retention bands shown herein. Likewise, if desired, this secondary retention system may be omitted from the embodiment of FIGS. 6 and 7.
Retention band 94 may either be assembled to trim member in the same manner as described above by first wrapping the retention band 94 around flange portion 84 with bead 96 being positioned in groove 88 and then securing the opposite ends 112 and 114 together or alternatively, ends 112 and 114 may first be secured together and thereafter bead 96 snapped over the axially inner edge 86 of the flange portion and into groove 88.
Referring now to FIGS. 10 and 11, there are shown two methods by which the opposite ends of any of the retention bands disclosed herein may be easily and suitably secured together. In the embodiment of FIG. 10, end portion 114 of retention band 94 is provided with a reduced width tab portion 116 which is positioned in overlapping relationship with the opposite end portion 112 and secured thereto in any suitable manner such as by spot welding. In order to prevent relative rotation between trim member 82 and retention band 94, annular groove 88 is interrupted by a protrusion 118 formed on the axially inwardly extending flange portion 84 which projects radially outwardly into an opening defined by opposed spaced edges 120 and 122 of bead 96. As the opposite ends 120 and 122 of bead 96 engage the protrusion or lug on either side, relative rotation between the trim member and retention band is effectively prevented.
Alternatively, as seen in FIG. 11, the opposite ends 124 and 126 of a retention band 128 may be positioned in abutting relationship and secured together by means of a tying member 133 fastened therebetween such as by suitable rivets 132 or the like. In this arrangement however, the axially outer edge 138 of one or both ends of the retention band will preferably be notched so as to accommodate a protrusion 136 or lug formed on the trim member 138.
An alternative arrangement for preventing relative rotation between the trim member and retention band is illustrated in FIG. 12. In this arrangement, a tab portion 140 is provided along the generally axially extending planar portion 142 of the retention band 144 which is deformed radially inwardly so as to engage the axially extending flange portion 146 of the trim member so as to prevent relative rotation therebetween. It should be noted that in some applications it may be desirable to utilize both the lug arrangements of FIGS. 10 and 11 in conjunction with one or more deformed tabs such as that illustrated in FIG. 12 so as to provide greater assurance than no relative rotation will occur.
Referring now to FIG. 13 another embodiment of the present invention is illustrated in which a retention band 148 is shown which is substantially identical to the retention band of FIGS. 6 and 7 with the exception that the bead 150 formed on the axially outer edge 152 thereof. In this embodiment, bead 150 is formed with a generally radially outwardly opening U-shape in transverse cross-section rather than the generally circular shape radially inwardly rolled bead previously disclosed. The assembly and operation of this embodiment is substantially identical to that previously disclosed.
While it will be apparent that the preferred embodiments of the invention disclosed are well calculated to provide the advantages and features above stated, it will be appreciated that the invention is susceptibel to modification, variation and change without departing from the proper scope of fair meaning of the subjoined claims.
