Description: DECORATIVE WHEEL TRIM FOR ' AUTOMOBILE WHEEL RIM BACKGROUND OF THE ' INVENTION This invention relates to a decorative wheel ring fastening arrangement for use on a vehicle wheel, in particular, for fastening to a passenger vehicle wheel rim. Various forms of decorative wheel rings and fastening arrangements for passenger vehicle wheel rims are known. One well-known such form of fastening means comprises an axially extending flange means on the ring and adapted to lie radially inwardly of the wheel flange when the ring is applied to the wheel, with means defining a plurality of clip-receiving recesses on the radially outer side of the flange means around the ring. Each of the recesses has an open axially inner end, with a spring clip for each recess, each clip comprising an interior portion inserted into and axially interlocked with its recess and an exterior portion extending exteriorly of its recess at the open axially inner end. Each exterior portion comprises a retaining finger extending both axially outwardly and radially outwardly for engagement with the wheel flange, the finger including a pair of circumferentially spaced, sharp pointed teeth projecting outwardly of the plane of the finger for biting engagement with the wheel flange. Each clip includes resilient means resiliently connecting its finger to the interior portion of its clip for enabling the finger to resiliently deflect toward its recess upon appli¬ cation of the ring to the wheel. Although mechanically effective for the purpose, such form of fastening means is relatively complicated in construction and costly to produce. The present invention aims to provide a decorative wheel ring fastening means which is no less effective for the purpose and is simpler in construction and thus less costly to produce, the decorative wheeltrim being fastened to the so-called hump of a passenger vehicle wheel rim. ^ OMPI Reference is made in this regard to the Tyre and Rim Association of Australia 1980 Standards Manual, which sets out the basic terms used in relation to wheel rims. Thus, in transverse cross section, such a rim consists of 5 an axially concentric arcuate transversely outer flange, which merges into an axially concentric transversely outer tyre-bead seat, which in turn merges into an axially concentric hump, which in turn merges into an axially concentric well, which in turn merges into an axially 10 concentric transversely inner tyre-bead seat, which in turn merges into an axially concentric heel, which in turn merges into an axially concentric arcuate transversely inner flange. SUMMARY OF THE INVENTION • j _2 In accordance with the present invention, there is provided a decorative wheel trim for an automobile wheel rim, said wheel trim comprising a castellated decorative ring member having resiliently deflectable castellation members adapted to engage under resilient deflection of the 20 castellation members, with the radially inner surface of the hump of the wheel rim to retain the decorative ring member in the area of the wheel rim bounded by the trans¬ versely outer flange of the wheel rim and the transversely outer corner of the well of the wheel rim, said decorative 25 ring member comprising a concentric substantially right- angle section having a concentric base portion for location transversely and radially outermost adjacent the radially inner surface of said outer flange of the wheel rim, and a castellated concentric flange portion for location adjacent 30 the radially inner surface of the outer tyre-bead seat of the wheel rim to engage under resilient deflection with the radially inner surface of said hump of the wheel rim, said castellation members having sufficient flexure in relation to the concentric flange portion of the decorative 35 ring member as to be deflectable adequately for resilient spring movement of said castellation members to engage with the radially inner surface of said hump of the wheel rim and _ OMPI retain the decorative ring member in the specified area of the wheel rim. Said resiliently deflectable castellation members may outstand from the concentric flange portion of the ring member substantially in alignment therewith, each having an end enlargement transversely at the inner marginal extremity of the castellation member for location to engage with the radially inner surface of said hump of the wheel rim. Thus, the decorative wheel trim of the invention may comprise an endless succession of resiliently deflect¬ able castellation members each with an end enlargement transversely at the inner marginal extremity of the castellation member, outstanding from the concentric flange portion of the ring member substantially in alignment -therewith, so that said ring member is wholly provided with castellation members having said end enlargements. Alternatively, the decorative wheel trim of the invention may comprise an interrupted endless succession of resiliently deflectable castellation members each with an end enlargement at the transversely inner marginal extremity of the castellation member, outstanding from the concentric flange portion of the ring member substantially in alignment therewith, a number of shortened and substant¬ ially non-deflectable castellation members without an end enlargement at the transversely inner marginal extremity periodically interrupting said endless succession of resiliently deflectable castellation members, so that said ring member has a plurality of castellation members without said end enlargements and is only partially provided with resiliently deflectable castellation members. In either instance, the resiliently deflectable castellation members may have a thickness materially less than that of the concentric flange portion of the concentric substantially right-angle section of the ring member so that the castellation members can flex at their juncture with said concentric flange portion sufficient for their resilient engagement with the radially inner surface of f OMPI ~ said hump of the wheel rim to retain the decorative ring member in that position. Moreover, in either instance, the ring member may comprise a concentric substantially right-angle section having a concentric base portion for location transversely and radially outermost adjacent the radially inner surface of said outer flange of the wheel rim, the transversely inner face of said concentric base portion of the ring member having oppositely inclined surfaces forming a concentric ridge for location adjacent the radially inner face of the transversely outer flange of the wheel rim, and a castellate concentric flange portion for location adjacent the radially inner surface of said outer tyre- bead seat of the wheel rim to engage tinder resilient deflection with the radially inner surface of said hump of the wheel rim, a concentric radially inner-divergent elongation of the concentric flange portion for location transversely and radially innermost adjacent the radially inner surface of the transversely outer corner of said well of the wheel rim, forming a concentric channel-form recess concentric inner-divergent elongation so that the castellation members have sufficient flexure in relation to the concentric flange portion of the decorative ring member for the stated purpose. In the case where the ring member comprises an interrupted endless succession of resiliently deflectable castellation members with an end enlargement at the trans¬ versely inner marginal extremity of the castellation member, outstanding from the concentric flange portion of the ring member substantially in alignment -therewith, with a number of shortened and substantially non-deflectable castellation members without an end enlargement at the transversely inner marginal extremities of the castellation members periodically interrupting said endless succession of resiliently deflectable castellation members, so that said ring member has a plurality of castellation members without said end enlargements and is only partially provided with resiliently deflectable castellation members, each of the plurality of shortened and substantially non-deflectable castellation members without said end enlargements at the transversely inner marginal extremities of the castellation members may be circumferentially wider than each of the castellation members having said castellation enlargements transversely at the inner marginal extremities of the castellation members, and the radially outer face of each of the plurality of shortened, and substantially non- deflectable castellation members without said end enlarge¬ ments transversely at the inner marginal extremities of the castellation members may have detent means for engage¬ ment with one of a plurality of spring clips adapted to be fitted to said ring member as supplementary fastening means for engagement with the radially inner surface of said hump of the wheel rim. In this case, the ring member may have a radially- disposed buttress member joining each shortened and substantially non-deflectable castellation member without an end enlargement to said concentric inner-divergent elongation of the concentric flange portion of said con¬ centric substantially right-angle section for strengthening each said shortened and substantially non-deflectable castellation member without an end enlargement, while each said spring clip may comprise resiliently deflectable inner legs adapted to lie against the radially inner face of one of the plurality of shortened and substantially non- deflectable castellation members without said end enlarge- ments, a resiliently deflectable mid-leg adapted to lie against the radially outer face of said one of the shortened and substantially non-deflectable castellation members without said end enlargements and having a detent for engagement with said detent-engagement means on said one of the shortened and substantially non-deflectable castellation members without said end enlargements, and resiliently deflectable outer legs adapted to be located away from the radially outer face of said one of the shortened and f OMPI ° substantially non-deflectable castellation members without said end enlargements and having sharp-pointed tooth-form notches for biting engagement with the radially inner surface of said hump of the wheel rim as secondary fast- ening means for the decorative ring member.

PRACTICAL EMBODIMENT OF THE INVENTION A practical embodiment of a wheel trim in accordance with the present invention is illustrated in the accompanying drawings, in which: Fig. 1 is a front elevational view of the decorative wheel trim according to the invention, in which the decorative ring member is wholly castellated; Fig. 2 is a part side elevational view of the decorative ring member shown in Fig. 1; Fig. 3 is a part cross-sectional view taken at line III-III of Fig. 1; Fig. 4 is a part cross-sectional view taken at line IV-IV of Fig. 3; Fig. 5 is a front elevational view of the decorative wheel trim according to the invention, in which the decorative ring member is partially castellated; Fig. 6 is a part side elevational view of the decorative ring member shown in Fig. 5; Fig. 7 is a part cross-sectional view taken at line VII-VII of Fig. 5; Fig. 8 is a part cross-sectional view taken at line VIII-VIII of Fig 5; Fig. 9 is a rear elevational view of a spring clip which can be used as fastening means for the decorative wheel trim shown in Figs» 5-8; < gUREA OMPI _ Fig. 10 is a side elevational view of the spring clip shown in Fig. 9; Fig. 11 is a front elevational view of the spring clip shown in Figs. 9-10; and Fig. 12 is a transverse outline of a passenger vehicle wheel rim to which the decor¬ ative wheel, ring member of Figs. 1-4, or the decorative ring member and spring clip fastening means of Figs. 5-12, is especially adapted to be fitted. Referring to the drawings, the decorative wheel trim illustrated therein is designed to be fastened to a passenger wheel rim 1 which in transverse cross section, consists of an axially concentric arcuate transversely outer flange 2, which merges into an axially concentric trans¬ versely outer tyre-bead seat 3, which in turn merges into an axially concentric hump 4, which in turn merges into an axially concentric well 5, which in turn merges into an axially concentric transversely inner tyre-bead seat 6, which in turn merges into an axially concentric heel 7, which in turn merges into an axially concentric arcuate transversely inner flange 8. In Figs. 1-4-of the drawings, the decorative wheel trim comprises a wholly castellated decorative ring member 9 in which castellation enlargements 10 are adapted to engage with the radially inner surface 11 of said hump 4 of the wheel rim 1 to retain the decorative ring member 9 in the area of the wheel rim 1 bounded by said transversely outer flange 2 of the wheel rim and the transversely outer corner 12 of the said well 5 of the wheel rim 1. Said decorative ring member 9 comprises a concentric substantially right-angle section 13 having a concentric base portion 14 for location transversely and radially outermost adjacent the radially inner surface 15 of said outer OMPI flange 2 of the wheel rim 1, and a wholly castellated concentric flange portion 16 for location adjacent the radially inner surface 17 of said outer tyre-bead seat 3 of the wheel rim 1 and having said castellation enlarge- ents 10 at transversely inner marginal extremities of the castellations members 10A for location to engage under resilient deflection with the radially inner surface 11 of said hump 4 of the wheel rim 1, and a concentric radially inner-divergent elongation 18 of the concentric flange portion 16 for location transversely and radially inner¬ most adjacent the radially inner surface 10 of the trans¬ versely outer corner 12 of said well 5 of the wheel rim 1. A concentric channel-form recess 20 is provided at the junction of said concentric flange portion 16 and said concentric inner-divergent elongation 18 so that the castellation members 10A can be resiliently deflected for spring engagement of said castellation enlargements 10 with the radially inner surface 11 of said hump 4 of the wheel rim 1. Base portion 14 of the right-angle section 13 of the decorative ring member 9 is substantially equilateral or isoceles triangular in shape. The transversely inner face of said base portion 14 thereby has an apex forming a concentric ridge 21 adjacent the radially inner face 15 of the transversely outer flange 2 of the wheel rim. The junction of the concentric flange portion 16 of the concentric substantially right-angle section 13 and the concentric inner divergent elongation 18 of the con¬ centric flange portion 16 of the concentric substantially right-angle section 13 of said decorative ring member 9 is substantially V-shape. The resultant concentric slot of the V-shape,forms the channel-form recess 20 at the trans¬ versely inner extremity of said concentric flange portion 16 and the divergent elongation 18 of said concentric flange portion 16, the junction area being relatively OMPI thicker than said concentric flange portion 16 and said divergent elongation 18 of the concentric flange portion 16 for the purpose. A part 22 of the decorative ring member 9 is removed for accommodating the tyre pneumatic valve not shown. A major portion of the removed part is a wholly removed area 23 of the concentric radially-inner divergent elongation 18 of the concentric flange portion 16, and a minor portion of the removed part is a partially removed area 24 of the radially inner surface of the concentric flange portion 16. The concentric channel-form recess 20 terminates on both sides of the partially removed area 24 of the radially inner surface of the concentric flange portion 16, in order not to weaken the decorative ring member 10 structurally at that area. In use, the decorative ring member 9 of Figs. 1-4 of the drawings is fitted to the wheel rim 1 by pressing said decorative ring member 9 transversely inwards until the ridge 21 of the base portion 14 of the right-angle section 13 of the decorative ring member 9 is adjacent the radially inner surface 15 of the transversely outer flange 2 of the wheel rim. The castellation enlargements 10 then frictionally engage under resilient deflection with the radially inner surface 11 of the hump 4 of the wheel rim, so as to retain the decorative ring member 9 in that position until a user desires to remove the decorative ring member 9 for replacement or other purposes. Thereupon, the decorative ring member 9 may be removed from the wheel rim by exerting sufficient force to overcome the frictional engagement of the castellation enlargements 10 under resilient deflection with the radially inner surface 11 of the hump 4 of the wheel rim, so as to allow the decorative ring member 9 to be retracted transversely outwardly of the wheel rim 1. in Figs. 5-8 of the drawings-, the decorative wheel trim comprises a partially castellated decorative ring member 25 in which castellation enlargements 26 on a majority of the castellation members 26A are adapted to engage with the radially inner surface 11 of said hump 4 of the wheel rim 1 to retain the decorative ring member 9 in the area of tiie wheel rim 1 bounded by said transversely outer flange 2 of the wheel rim and the transversely outer corner 12 of the said well 5 of the wheel rim 1. Said decorative ring member 25 comprises a concentric substantially right-angle section 27 having-a concentric base portion 28 for location transversely and radially outermost adjacent the radially inner surface 15 of said outer flange 2 of the wheel rim 1, and a partially castellated concentric flange portion 30 for location adjacent the radially inner surface 17 of said outer tyre- bead seat 3 of the wheel rim 1. The castellation enlarge¬ ments 10 are disposed at transversely inner marginal extremities of a majority of the castellation members 26 for location to engage under resilient deflection with the radially inner surface 11 of said hump 4 of the wheel rim 1. A number of shortened and substantially non- deflectable castellation members 26B without castellation enlargements at their transversely inner marginal extremities, periodically interrupt the endless succession of resiliently deflectable castellation members 26A with end enlargments 10, so that said ring member 9 has a plurality of castellation members without said end enlarge¬ ments and is only partially provided with resiliently deflectable castellation members. Castellation members 26B without said castellation enlargements are conveniently σircumferentially wider than castellation members 26A having said castellation enlargements 10 at their trans¬ versely inner marginal extremities. A concentric radially inner-divergent elongation 32 of the concentric flange portion 30 extends for location transversely and radially innermost adjacent the radially OMPI inner surface 10 of the transversely outer corner 12 of said well 5 of the wheel rim 1. A concentric channel-form recess 33 is provided at the junction of said concentric flange portion 30 and said concentric inner-divergent elongation 32 so that the castellation members 26A can be resiliently deflected for spring engagement of said castellation enlargements 10 with the radially inner surface 11 of said hump 4 of the wheel rim 1. The radially outer face of each shortened and substantially non-deflectable castellation member 26B has a detent-engaging indentation 29 whereby a plurality of spring clips 36 can be fitted to the decorative ring member 25 as a supplementary fastening means adapted to engage with the radially inner surface 11 of said hump 4 of the wheel rim 1. Base portion 28 of the right-angle section 27 of the decorative ring member 25 is substantially equilateral or isoceles triangular in shape. The transversely inner face of said base portion 28 thereby has an apex forming a concentric ridge 34 adjacent the radially inner face 15 of the transversely outer flange 2 of the wheel rim 1. The junction of the concentric flange portion 30 of the concentric substantially right-angle section 27 and the concentric inner divergent elongation 32 of the concentric flange portion 30 of the concentric substantially right- angle section 27 of said decorative ring member 25 is substantially V-shape. The resultant concentric slot of the V-shape, forms the channel-form recess 33 at the trans¬ versely inner extremity of said concentric flange portion 30 and the divergent elongation 32 of said concentric flange portion 30, the junction area being relatively thicker than said concentric flange portion 30 and said divergent elongation 32 of the concentric flange portion 30 for the purpose. A radially-disposed buttress member 31 joins each shortened and substantially non-deflectable castell¬ ation member 26B without an end enlargement to said concentric inner-divergent elongation 32 of the concentric flange portion 30 of said concentric substantially right- angle section 27 for strengthening each said shortened and substantially non-deflectable castellation member 26B without an end enlargement. A part of the decorative ring member 25 -is removed for accommodating the tyre pneumatic valve not shown, a major portion of the removed part being a wholly removed area 35 of the concentric radially-inner divergent elongation 32 of the concentric flange portion 30, and a minor portion of the removed part being a partially removed area 35Aof the radially inner surface of the concentric flange portion 30. The concentric channel-form recess 33 terminates on both sides of the partially removed area 35A ofthe radially inner surface of the concentric flange portion 30, in order not to weaken the decorative ring member 25 structurally at that area. Each spring clip 36 is substantially ϋ-shape and has inner legs 37 and outer legs 38 joined by a half-round return bend 39, with mid-leg 40 projecting from the half- round return bend into a plane substantially midway between the plane of the inner legs 37 and the plane of the outer legs 38. In fabricating said spring clips 36, a central portion of one side of a ϋ-shape can be displaced inwardly whereby the mid-leg 40 is formed, leaving undisplaced leg portions forming the inner legs 37 on both sides of the displaced central portion, a detent 41 being pressed into the mid-leg 40. A central portion of the other side of the ϋ-shape sheet is expressed therefrom, leaving leg portions forming the outer legs 38, sharp-pointed tooth-form notches 42 being cut into the outer marginal edge of each outer leg 38 near the half-round return bend 39. OMPI In use, the decorative ring member 25 of Figs. 5-8 of the drawings has a plurality of the spring clips 36 fitted thereto by locating said inner legs 37 of the spring clip 36 in the channel-form recess 33 and pressing the spring clips 36 transversely inwardly whereby each said mid- leg 40 moves transversely inwardly along the radially outer face 35 of said concentric flange portion 30 until the* detent means 41 in the mid-leg 40, engages with a corres¬ ponding indentation 29. The assembly of the decorative ring member 25 and the plurality of spring clips 36 is then fitted to the wheel rim by pressing the assembly transversely inwards until the ridge 34 of the base portion 28 of the right-angle section 27 of the decorative ring member 25 is adjacent the radially inner surface 15 of the transversely outer flange 2 of the wheel rim. The castellation enlargements 26 then friction- ally engage under resilient deflection with the radially inner surface 11 of the hump 4 of the wheel rim 1, while the sharp-pointed tooth-form notches 42 of the spring clips 36 bitingly engage with the radially inner surface 11 of the hump 4 of the wheel rim, so as to retain the decorative ring member 25 in that position until a user desires to remove the decorative ring member 25 for replacement or other purposes. Thereupon, the decorative ring member 25 may be removed from the wheel rim 1 by exerting sufficient force to overcome the frictional engagement of said castellation enlargements 26 and the biting engagement of said sharp- pointed tooth-form notches 42 with the radially inner surface 11 of the hump 4 of the wheel rim, so as to allow the decorative ring member 25 to be retracted transversely outwardly of the wheel rim 1. Although the resiliently deflectable castellation members preferably outstand from the concentric flange portion of the decorative ring member in alignment therewith and have an end enlargement transversely at the inner OMPI marginal extremity of each castellation member for location to engage under resilient deflection with the radially inner surface of said hump of the wheel rim, said castell¬ ation members may be without end. enlargements and may angularly incline radially outwards or curve radially out¬ wards from the concentric flange portion of the decorative ring member for the outer ends of the castellation members to engage under resilient deflection with the radially inner surface of the hump of the wheel rim to retain the decorative ring member in the area of the wheel rim bounded by the transversely outer flange of the wheel rim and the transversely outer corner of the well of the wheel rim. Persons skilled in the art will appreciate that the decorative wheel trim of the invention, in being indicated to be a ring member essentially comprising a concentric substantially right-angle section having a concentric base portion and a concentric flange portion and a concentric radially inner-divergent elongation of the concentric flange portion as described, may have a nave in the form of a convex-dished or similar disc-form decorative member fitting within the inner periphery of the ring member. Said disc-form decorative member may have a continuous disc-form appearance or a non-continuous disc- form appearance, and may be integral with the ring member or non-integral with the ring member. For instance, said disc-form decorative member may have a solid convex disc appearance or may have a lattice or other open-work convex disc appearance. Also, said disc-form decorative member and the ring member may be in the form of an integral, single plastics moulding, in which the periphery of the disc-form decorative member extends from the inner periphery of the ring member, or said disc-form decorative member may be in the form of a non-integral, separate plastics moulding, which can be suitably fixed within the inner periphery of the ring member, say by rivetting of a concentric flange of the disc-form decorative member to the concentric flange portion of the ring member.
