Opfindelsen angår en pyntehjulkapsel til automobiler som nærmere angivet i krav l's indledning.The invention relates to an automobile ornament wheel capsule as further specified in the preamble of claim 1.

5 De fleste pyntekapsler til biler er i deres opbygning tilpasset en bestemt vogntype, idet der findes fremspring, noter eller lignende på fælgen, til hvilke pyntekapslen kan fastgøres sikkert. Disse fastgørelsesmuligheder er imidlertid meget forskellige for de forskellige vogntyper.5 Most car ornaments in their design are adapted to a specific type of carriage, with projections, notes or the like on the rim, to which the decorative can be securely attached. However, these attachment options are very different for the different vehicle types.

Pyntekapslerne af den omhandlede type, som kan klemmes sikkert fast på en fælg, er baseret på den omstændighed, at automobilfælge i en bestemt størrelsesklasse selv ved forskellig konstruktion altid har samme diameter af den 15 indvendige skulder, hivlkct vil sige, at sådanne pynte kapsler kan benyttes til de mest forskellige vogntyper. En sikkor forbindelse mol lom fælg og pyntekapsel forudsætter dog en meget høj fastholdolseskraft hos do metalliske klemtunger, så at pyntekapslen ikke løsner sig fra fælgen 20 på f.eks. en ujævn vej. Ved de kendte pyntekapsler opnås der ganske vist under normale forhold en tilstrækkelig fastholdelseskraft, men det har vist sig, at de kan løsne sig ved hyppige og hurtigt efter hinanden følgende stærke opbremsninger. Årsagen er den stærke opvarmning af fælg-25 legemet til temperaturer på mere end 100°C, hvorved forankringen af afdækningsskiven af formstof til de metalliske klemelementer - som regel under varig plastisk deformation - giver efter, hvorved fastholdelseskraften reduceres betydeligt.The ornamental caps of the type in question, which can be clamped securely to a rim, are based on the fact that even in different sizes, automobile rims of a certain size always have the same diameter of the inner shoulder, which means that such ornamental capsules can used for the most different types of vehicles. However, a secure connection between the pocket rim and the ornamental capsule requires a very high retaining force of the metallic clamping tongues, so that the ornamental capsule does not detach from the rim 20 on e.g. a bumpy road. While the known ornamental capsules, under normal conditions, sufficient retention force is obtained, it has been found that they can loosen by frequent and rapidly successive strong braking. The reason is the strong heating of the rim body to temperatures of more than 100 ° C, whereby the anchoring of the plastic disc cover to the metallic clamping elements - usually under durable plastic deformation - yields, thereby considerably reducing the retention force.

Fra DE-A-31 37 319 kendes en hjulkapsel af den omhandlede art til en speciel fælgform. Montagen af denne hjulkapsel er forholdsvis omstændelig, så at den kun kan foregå på fabrik eller værksted. Desuden kendes der fra 35 DE-A-32 38 259 hjulkapsler til fælge i en bestemt størrel sesklasse til forskellige biler. De kan som regel monteres af brugeren selv. Også disse hjulkapsler har en støttering, - 2 -From DE-A-31 37 319 a wheel capsule of the kind in question is known for a special rim shape. The mounting of this wheel capsule is relatively cumbersome, so that it can only be carried out at the factory or workshop. Furthermore, from 35 DE-A-32 38 259 wheel caps are known for rims of a certain size class for different cars. They can usually be mounted by the user himself. Also these wheel caps have a support ring, - 2 -

som imidlertid praktisk taget kun er indspændt og fastholdt til klemelementerne, hvorved der atter opstår montageproblemer.however, which is practically only clamped and retained to the clamping elements, which again causes mounting problems.

5 Til grund for opfindelsen ligger den opgave at anvise en pyntehjulkapsel af den angivne art, hvis fastholdelseskraft opretholdes specielt ved stærk opvarmning af fælgen.The object of the invention is to provide an ornamental wheel capsule of the specified type, the retaining power of which is maintained especially by strong heating of the rim.

Denne opgave løses ifølge opfindelsen ved den i krav l's 10 kendetegnende del anførte udformning.This task is solved according to the invention by the design according to the characterizing part of claim 10.

Delene af denne hjulkapsel kan sammensættes på meget enkel måde. Afdækningsskiven kan være den basis, på hvilken støtter.ingon anbringes på en sådan måde, at den griber ind 15 i forankringsskakternos slids. Vod indstikning af klem elementerne i forankringsskakterne bliver ikke blot hjulkapslen kompletteret, men samtidig fikseres også støtteringen sikkert dertil. Den færdige hjulkapsel kan da uden videre indsættes i en hjulfælgs indvendige skulder. Dette 20 kræver hverken særligt værktøj eller fagfolk. Dermed er støtteringen ikke blot fikseret til skiven, men den danner under brugen også et tilstrækkeligt fast modleje for de mod fælgens indvendige skulder støttende klemelementer.The parts of this wheel capsule can be assembled in a very simple way. The cover disc may be the base on which the support ingon is placed in such a way that it engages 15 in the slot of the anchoring shafts. When inserting the clamping elements in the anchoring shafts, the wheel cap is not only supplemented, but at the same time the support ring is also securely fixed to it. The finished wheel cap can then easily be inserted into the inner shoulder of a wheel rim. This 20 requires no special tools or professionals. As a result, the support ring is not only fixed to the disc, but during use it also forms a sufficiently fixed backrest for the clamping elements supporting the inner shoulder of the rim.

Den beholder hele tiden en med skivens centrum koncentrisk 25 stilling. Ved denne opbygning af hjulkapslen kan afdækningsskiven fremdeles være helt af formstof, så at fordelene ved absolut korrosionsbestandighed og bekvem rengøring bibeholdes.It always maintains a concentric position with the center of the disc 25. In this construction of the wheel capsule, the cover disc can still be completely plastic so that the benefits of absolute corrosion resistance and convenient cleaning are maintained.

30 Ifølge opfindelsen kan holdeansatsen være anbragt i nærheden af klemtungens bøjezone og være trykket ud af klemelementet i retning mod skivens centrum, og støtteringen kan ligge an mod klemeleemntet på den side, som vender mod skivens centrum. Derved opnår næsen, der tjener som holde-35 ansats for støtteringen, en ren sikringsfunktion, og den skal ved en højere varmepåvirkning af fælgen selv ikke overføre kræfter fra støtteringen til klemelementet, så at - 3 -In accordance with the invention, the holding member may be positioned near the bending zone of the clamping tongue and be pushed out of the clamping element in the direction towards the center of the disc, and the support ring may abut against the clamping member on the side facing the center of the disc. In this way, the nose, which serves as a holding member for the support ring, achieves a clean securing function and it does not, by a higher heat influence of the rim, transfer power from the support ring to the clamping element, so that - 3 -

en udformning som tynd bliklaske er helt tilstrækkelig. Ved anbringelsen af næsen i nærheden af klemtungens bøjezone kan klemelementerne skubbes næsten helt ind i afdækningsskivens forankringsskakter. Alene ved indgangen til 5 skakten må der forblive et vist rum frit for støtteringen.a design like thin tin can is quite sufficient. By placing the nose near the bending zone of the clamping tongue, the clamping elements can be pushed almost completely into the anchor shafts of the cover disc. Only at the entrance to the shaft a certain space must remain free of the support ring.

Ifølge en alternatv udførelsesform for opfindelsen kan holdeansatsen omslutte støtteringen krogagtigt. Ved denne udførelsesform opnås - ved den krogformede holdeansats1 10 snapindgreb med støtteringen - denne entydigt definerede stilling.According to an alternative embodiment of the invention, the holding means can enclose the support ring hook-like. In this embodiment, - by the hook-shaped holding mechanism110 snap engagement with the support ring - this uniquely defined position is obtained.

I en udførelsesform for opfindelsen kan støtteringen og klemtungernes støtteender ligge i omtrent samme radialplan.In one embodiment of the invention, the support ring and the support ends of the clamping tongues may lie in approximately the same radial plane.

15 Derved sikres, at klemtungernes radiale klemkræfter ved en høj termisk belastning af fælgen virker umiddelbart på støtteringen, hvilket vil sige, at der praktisk taget ikke indtræder nogen yderligere drejningsmomenter på klemelementerne, som kunne føre til en deformation af skivens form-20 stofforankring. Klemelementerne forbliver således stadig i deres oprindelige stilling.In this way, the radial clamping forces of the clamping tongues, at a high thermal load on the rim, are ensured immediately on the support ring, which means that practically no further torque occurs on the clamping elements which could lead to a deformation of the disc's anchorage. Thus, the clamping elements still remain in their original position.

En yderligere udformning er ejendommelig ved, at klemtungen i tilslutning til bukningen er udformet bue-25 agtigt med en lignende, men mindre krumning, hvorved den frie ende af klemtungen er udformet som en støttefod, som ligger over for fastholdelsesenden, og klemtungen har i området mellem bukningen og sin største afstand fra fastholdelscsendcn nogle holdeansatser, som er rettet bort 30 fra fastholdelsesenden.A further embodiment is characterized in that the clamping tongue is adjacent to the bend with a similar but smaller curvature, whereby the free end of the clamping tongue is formed as a supporting foot which faces the retaining end and the clamping tongue has in the region between the bend and its greatest distance from the retention transmits some retaining means directed away from the retaining end.

Ved benyttelsen af dette klemelement frembringes de fornødne klemkræfter ikke alene ved bøjning i området for ombukningen, men også af støttefoden, som ved monteret afdæk-35 ningsskive støtter mod en flade på afdækningsskiven, som ligger over for hjulfælgens indvendige skulder. Deformationen i området for ombukningen forbliver derved mindre.By using this clamping element, the necessary clamping forces are produced not only by bending in the area of the bend, but also by the support foot, which, with mounted cover plate, abuts against a surface of the cover plate, which is opposite to the inner rim of the wheel rim. The deformation in the area of the bend thus remains less.

Klemelementet kan i sin helhed fremstilles af tyndere blikplade. Holdeansatserne i området for den største afstand for klemtungen anbriber den indvendige skulder på fælgen og fastholder afdækningsskiven mod hjulfælgen.The clamping element can be made entirely of thinner sheet metal. The holders in the area for the greatest distance of the pinch tongue engage the inner shoulder of the rim and hold the cover disc against the wheel rim.

Ved en foretrukken udførelsesform svarer længden af klemtungen omtrent til længden af fastholdelsesenden. Længden af klemtungen kan imidlertid også tilpasses de til enhver tid herskende forhold.In a preferred embodiment, the length of the pinch tongue corresponds approximately to the length of the retaining end. However, the length of the pinch can also be adapted to the conditions prevailing at any time.

1010

Hensigtsmæssigt bukkes holdeansatserne trekantformet ud af området for klemtungens siderande. I så fald har holdeansatserne for hver klemtunge tilstrækkelig stor afstand, så at hver holdeansats kan tilvejebringe sin egen fasthold-15 elseskraft.Conveniently, the holders are bent triangularly out of the area of the lateral edges of the pinch. In that case, the holders for each clamping tongue have a sufficiently large distance so that each holding member can provide its own holding power.

Ved dette klemelement kan fastholdelseskræfterne imidlertid også indstilles ved, at klemtungen i området mellem holdeansatserne og støttefoden har en mindre bredde. Uafhængigt 20 deraf eller som et yderligere træk kan klemtungen i området mellem holdeansatserne og støttefoden have en længdeslids.However, for this clamping element, the retaining forces can also be set by having a smaller width in the area between the holding posts and the support foot. Independently thereof or as a further feature, the clamping tongue in the area between the holding posts and the support foot may have a longitudinal slot.

Med denne foranstaltning kan den kraft, hvormed holdeansatserne trykkes mod fælgens indvendige skulder, påvirkes i et bredt område.With this measure, the force by which the holders are pressed against the inner shoulder of the rim can be affected in a wide area.

Afdækningsskiven 2 kan til udsmykning have flere gennembrydninger 3. Hjulkapslen 1 er beregnet til at kunne klemmes sikkert fast på den rundt-gående indvendige skulder 4 på en med stiplede linier antydet hjulfælg 5. I skivens 2 randområde findes der re-30 gelmæssigt fordelt langs omkredsen flere fastgørelsesfremspring 6, som hver har en aksial spalteformet skakt 7 med støtteribber 8. Som det nærmere ses i fig. 3-6, er der i hver skakt 7 indskubbet er klemelement 9 i form af en aflang blikstrimmel, hvis frie ende, som rager ud af 35 skakten 7, er bukket mere end 90° til en fjedrende klemtunge 10. Ud af klemelementet 9 er der i området for skakten 7 trykket to modhager 11, som sørger for en sikkerFIG. 1 and 2 show an ornamental wheel capsule 1, icing for automobiles whose base body consists of a circular, slightly curved 25 wrap cover disc of plastic material. The cover disc 2 can have several breakthroughs for decorating 3. The wheel cap 1 is intended to be securely clamped on the circumferential inner shoulder 4 on a wheel rim indicated by dotted lines 5. In the peripheral area of the disc 2, there are generally distributed along the circumference. a plurality of fastening projections 6, each of which has an axial slit-shaped shaft 7 with supporting ribs 8. As will be more closely seen in FIG. 3-6, there is inserted in each shaft 7 a clamping element 9 in the form of an elongated tin strip, the free end of which protrudes from the shaft 7 is bent more than 90 ° to a resilient clamping tongue 10. Out of the clamping element 9 is in the area of the shaft 7, two barbs 11 are pressed, which provide a safe

- 6 - forankring af klemelementet 9 i skakten 7. Klemtungen 10 kan derfor ved indskubning af hjulkapslen 1 i fælgen 5 bringes under en så høj forspænding, at der opnås en upåklagelig og sikker fastklemning på den indvendige 5 skulder 4.- 6 - anchoring the clamping element 9 in the shaft 7. The clamping tongue 10 can therefore be brought, by pushing the wheel capsule 1 into the rim 5, under such high tension that an impeccable and secure clamping is achieved on the inner 5 shoulder 4.

Til forebyggelse af en deformation af fastgørelsesfremspringene 6 og dermed en formindskelse af fastholdelseskraften mellem klemtungen 10 og den indvendige 10 skulder 4 selv ved stor varmebelastning af fælgen 5 støtter klemelementerne 9 radialt indad mod en med skivens centrum koncentrisk metallisk støttering 12, hvis stilling er vist i fig. 1 med punkterede linier. Støtteringen 12 er indlagt i en slids 13, som findes ved indgangen til hver 15 forankringsskakt 7, og som er orienteret i skivens 2 periferiretning. Støtteringen 12 kan ved hjulkapslens 1 montage midlertidigt indlægges i slidsen 13 og fikseres endeligt ved hjælp af nogle på klemelementerne 9 udformede holdeansatser 14.In order to prevent a deformation of the fastening projections 6 and thus a reduction of the retaining force between the clamping tongue 10 and the inner 10 shoulder 4 even at high heat load of the rim 5, the clamping elements 9 radially inwardly against a concentric metallic support ring 12, whose position is shown in FIG. 1 with dashed lines. The support ring 12 is inserted into a slot 13, which is located at the entrance to each anchor shaft 7, and which is oriented in the circumferential direction of the disc 2. At the mounting of the wheel cap 1, the support ring 12 can be temporarily inserted into the slot 13 and finally fixed by means of some holding brackets 14 formed on the clamping elements 9.

20 I det i fig. 3 og 4 viste udførelseseksempel er holdeansatsen 14 en omtrent vinkelret på skivens centrum af klemelementets 9 plademateriale udtrykket næse, som spærrer periferislidsen 13 mod dens åbne side. Holdeansatsen 14 25 befinder sig således i nærheden af klemtungens 10 bøje- zone 15, og støtteringen 12 ligger umiddelbart an mod klemelementet 9 på den mod skivens centrum vendende side. Støtteringen 12 og støtteenden 16 af klemtungen 10 på den indvendige skulder ligger da omtrent i samme radialplan, 30 så at klemtungens 10 radiale klemkraft umiddelbart kan overføres på støtteringen 12.20 In the embodiment of FIG. 3 and 4, the holding bracket 14 is approximately perpendicular to the center of the disc of the plate material of the clamping element 9, the term nose, which locks the peripheral slot 13 towards its open side. Thus, holding bracket 14 25 is in the vicinity of the flexural zone 15 of the clamping tongue 10, and the supporting ring 12 is immediately adjacent to the clamping element 9 on the side facing the center of the disc. The support ring 12 and the supporting end 16 of the pinch tongue 10 on the inner shoulder are then approximately in the same radial plane, so that the radial squeezing force of the pinch tongue 10 can be immediately transferred to the support ring 12.

Skakten 7 er i udførelseseksemplet ifølge fig. 3, 5 og 6 udvidet i retning mod skivens centrum, så at der bliver 35 tilstrækkelig plads til optagelse af støtteringen 12 på den mod skivens centrum vendende side af klemelementet 9.The shaft 7 is in the embodiment of FIG. 3, 5 and 6 extended in the direction towards the center of the disc so that there is sufficient space for accommodating the support ring 12 on the side facing the center of the disc 9 of the clamping element 9.

klemelementerne ved hjælp af modhagerne 11 er skaktens tværsnit dog omtrent i det halve område spærret af flere længderibber 17, mod hvis ende støtteringen 12 ligger an.the clamping elements by means of the barbs 11, however, the cross-section of the shaft is approximately halfway blocked by several longitudinal ribs 17, the end of which of the support ring 12 abuts.

5 Fig. 7 viser en anden udførelsesform for et klemelement 18, hvor holdeansatsen 19 for støtteringen 7 har en krogformet næse, som er trykket ud af klemelementet 18, og som delvis omslutter støtteringen 12. I denne udførelsesform er bredden af forankringsskakten 20 umiddelbart tilpasset klemele-10 mentet 18, medens støtteringen 12 uden for skakten 20 ligger an mod fastgørelsesfremspringet 21 for klemelementet 18. Også i dette tilfælde ville det dog være nok med et fastholdelsesorgan for støtteringen 12, som i analogi med udførelseseksemplet ifølge fig. 3 og 4 alene 15 er trykket retvinklet ud af klemelementet. Centreringen af ringen 12 ville da også være sikret ved hjælp af de regelmæssigt langs periferien fordelte klemelementer.FIG. 7 shows another embodiment of a clamping element 18, wherein the holding ring 19 of the support ring 7 has a hook-shaped nose which is pushed out of the clamping element 18 and partially encloses the support ring 12. In this embodiment, the width of the anchoring shaft 20 is immediately adapted to the clamping element 10. 18, while the support ring 12 outside the shaft 20 abuts the fastening projection 21 of the clamping element 18. However, in this case too, a retaining means for the support ring 12 would suffice, as in analogy to the embodiment of FIG. 3 and 4 alone 15 are pressed at right angles out of the clamping element. The centering of the ring 12 would then also be ensured by means of the clamping elements regularly distributed along the periphery.

Ved udførelsesformen ifølge fig. 8-11 støtter klemele-20 menterne 19 radialt indad mod den med skivens centrum koncentriske metalliske støttering 12, hvis stilling i fig. 1 er skitseret ved hjælp af stiplede linier.In the embodiment of FIG. 8-11 support the clamping elements 19 radially inwardly against the metallic support ring 12 concentric with the center of the disc, whose position in FIG. 1 is outlined by dotted lines.

Som det især fremgår af fig. 8-11, er klemtungen 10 i hvert 25 klemelement 9 i forbindelse med ombukningen 31 udformet bueagtigt med en lignende, men dog mindre krumning end ombukningen 31. Den frie ende af klemtungen 10 er udformet som en over for holdeenden 32 liggende støttefod 37, nemlig ved den viste udførelsesform som en ombukning med modsat 30 krumning. Endvidere har hver klemtunge 10 i området mellem ombukningen 13 og den største afstand fra holdeenden 32 nogle holdeansatser, der er udformet som modhager 38, og som er rettet væk fra holdeenden 32. Længden af hver klemtunge 10 svarer omtrent til længden af den tilhørende hol-35 deende 32. Holdeansatserne eller modhagerne 38 har trekantform og er bukket ud af området for klemtungens 10 siderande .As can be seen in particular from FIG. 8-11, the clamping tongue 10 of each clamping element 9 in connection with the bend 31 is designed to be arcuate with a similar but smaller curvature than the bend 31. The free end of the clamping tongue 10 is formed as a supporting foot 37 which is opposite the holding end 32, namely in the illustrated embodiment as a bend with opposite curvature. Furthermore, each clamping tongue 10 in the region between the bend 13 and the largest distance from the retaining end 32 has some holding brackets which are designed as barbs 38 and which are directed away from the retaining end 32. The length of each clamping tongue 10 corresponds approximately to the length of the corresponding retaining member. 35 holders or barbs 38 have a triangular shape and are bent out of the region of the side edges of the pinch tongue 10.

Ved den viste udførelsesform har klemtungen 10 endvidere i området mellem modhagerne 38 og støttefoden 37 mindre bred-= de. Ved valg af en passende bredde kan klemvirkningen af hver klemtunge 10 indstilles. Yderligere indstillingsmu-5 ligheder opnås, når klemtungen 10 som vist i området mellem modhagerne 38 og støttefoden 37 har en længere eller kortere længdeslids 39, som åbner sig i støttefodens 37 område.Furthermore, in the embodiment shown, the pinch tongue 10 is less wide in the area between the barbs 38 and the support foot 37. By selecting a suitable width, the clamping effect of each clamping tongue 10 can be adjusted. Further adjustment possibilities are obtained when, as shown in the region between the barbs 38 and the support foot 37, the clamping tongue 10 has a longer or shorter longitudinal slot 39 which opens into the area of the support foot 37.

10 I fig. 8 ses, hvorledes klemelementerne 9 ved monteret afdækningsskive 2 spænder sig fast mellem den indvendige skulder 4 på hjulfælgen 5 og en over for den indvendige skulder 4 liggende støtteflade 40 på afdækningsskiven 2. Klemtungen 10 angriber hjulfælgens 5 indvendige skulder 4 15 med det afsnit, som ligger længst væk fra holdeenden 32, eller med modhagerne 38. Samtidig støtter støttefoden 37 mod støttefladen 40, som dannes af ydersiden af en væg i skakten 7. Klemkræfterne frembringes ikke blot af klemtungens 10 fjederkraft, men også af støttefodens 7 støtte-20 kraft.10 In FIG. 8 shows how the clamping elements 9 of the mounted cover disc 2 are fixed between the inner shoulder 4 of the wheel rim 5 and a supporting surface 40 of the cover disc 2 against the inner shoulder 4. The clamping tongue 10 engages the inner shoulder 4 of the wheel rim 5 with the section which is furthest away from the holding end 32, or with the barbs 38. At the same time, the support foot 37 supports the support surface 40, which is formed by the outside of a wall in the shaft 7. The clamping forces are generated not only by the spring force of the clamping tongue 10, but also by the support 20 of the support foot 7.
