Description

Denne oppfinnelse angår en skibinding av sål ek lemme typen med en i et tåbeslag lagret, fjærende klembbyle og en svingbar holderkrok, hvilken boyle er rettet foran ho Iderkrok en med en gripedel. En binding av dette slag er f. eks. vist i norsk utlegnings-skrift 125 713. Bbylen er her trukket frem foran holderkroken for å lette fastspenningen og samtidig beskytte kroken mot stot, Bbylen er forsynt med et tverrste.g for samvirke med kroken. En ulempe ved denne binding er at fastklemmingen blir dårligere ved skråbe1 astninger av bbylen, f.eks. avhengig av ujevn tykkelse av sålekanten. Ennvidere kreves der ganske kraftig gods i boylen med derav fblgende hbyere vekt, hvilket er uheldig ved bindinger for konkurransebruk. Endelig er det ikke mulig å spenne og lose bindingen ved hjelp av en skistav, hvilket er bnskelig for turistbruk. This invention relates to a ski binding of the sole oak limb type with a spring-loaded clamp bolt stored in a toe bracket and a pivotable holding hook, which bolt is directed in front of the hook with a gripping part. A binding of this kind is e.g. shown in Norwegian layout document 125 713. The Bbyle is here pulled forward in front of the holding hook to ease the clamping and at the same time protect the hook from impact, the Bbyle is provided with a crossbar g for cooperation with the hook. A disadvantage of this binding is that the clamping becomes worse in the case of oblique loading of the bbybel, e.g. depending on the uneven thickness of the sole edge. Furthermore, rather heavy goods are required in the boyle with a consequent higher weight, which is unfortunate for bindings for competition use. Finally, it is not possible to tighten and loosen the binding with the help of a ski pole, which is desirable for tourist use.

Hvis boylen dessuten trykkes ned eller ho 1 derkrok en ved feiltagelse tvinges bort fra bbylen, hvilket frem for alt lett kan skje ved at en konkurrents skistavspiss ved en skikonkurranse med stort de 11ageranta 11 og felles start, påvirker bbylen eller holderkroken, således at forbindelsen mellom denne og bbylen loses ut og stbvelen lbsner fra tåbeslaget. If the boyel is also pressed down or a hook is accidentally forced away from the car, which above all can easily happen if the tip of a competitor's ski pole in a ski competition with large de 11ageranta 11 and joint start, affects the car or the holding hook, so that the connection between this and the bbyle are unloaded and the stemwell is released from the toe fitting.

Formålet med oppfinnelsen er å eliminere de nevnte ulemper, hvilket oppnås ved de i de etterfølgende patentkrav angitte trekk. Fordelene med denne skibinding skal belyses ytterligere i det fblgende ved beskrivelse av to utfbre1seseksemp1 er under henvisning til tegningene, hvis fig. 1 viser et sideoppriss av en utfbrelse, The purpose of the invention is to eliminate the aforementioned disadvantages, which is achieved by the features specified in the subsequent patent claims. The advantages of this ski binding shall be explained further in the following by describing two manufacturing examples with reference to the drawings, whose fig. 1 shows a side elevation of an embodiment,

fig. 2 viser samme utfbrelse i grunnriss, fig. 3 viser et sideoppriss av en annen utfbrelse, fig. 4 viser et grunnriss av samme utfbrelse, fig. 5 viser i sideoppriss en variant av utfbrelsen ifblge fig. 1 og 2, og fig. 6 viser et grunnriss av utfbrelsen ifblge fig. 5. fig. 2 shows the same embodiment in plan view, fig. 3 shows a side elevation of another embodiment, fig. 4 shows a floor plan of the same embodiment, fig. 5 shows in side elevation a variant of the embodiment according to fig. 1 and 2, and fig. 6 shows a floor plan of the embodiment according to fig. 5.

Den på fig. 1 og 2 viste utfbrelse av skibindingen består av et tåbeslag 10, i hvis sidevegger 11 der er svingbart lagret en fjærende klemmebbyle 12. I en for over rettet forlengelse av tåbeslaget er der svingbart lagret en holderkrok 13 som er utfort med flere hakk. Forbvrig er tåbeslaget på vanlig måte forsynt med tre skruehull 14 og tre oppadrettede, tilspissede tapper 15 for samvirke med hull i stbvelsålen. The one in fig. The embodiment of the ski binding shown in 1 and 2 consists of a toe bracket 10, in whose side walls 11 a springy clamping bracket 12 is pivotably mounted. In an extension of the toe bracket directed above, a holding hook 13 is pivotably mounted which is provided with several notches. In addition, the toe fitting is provided in the usual way with three screw holes 14 and three upwardly pointed pins 15 for cooperation with holes in the sole.

Bbylen 12 er fort. frem foran kroken 13 oy den.s to sidedeler er utformet med mot hinannen rettede innbuktninger, således at der dannes en fremre, s 1 o'yf ef orme t yriperiel 16. Bak kroken fåes derved et parti 1.7 som er rettet inn mot bindingens 'miritplan for samvirke med kroken 13 som til delte formål er utfort, dobbelt, således at et. ben 18 kan hakes fast rundt hver t parti 17. Bbylen 12 is fast. forward in front of the hook 13 and its two side parts are designed with indentations directed towards each other, so that a front, s 1 o'yf ef orme t yriperiel 16 is formed. Behind the hook, a part 1.7 is thereby obtained which is directed towards the binding's mirit plan for cooperation with hook 13 which is laid out for shared purposes, double, so that a legs 18 can be hooked around each section 17.

Ved at et ben av kroken fastholder hver halvdel av bbylen oppnås en bedre fastk1 emming, selv om bbylen skulle være skjevt belastet. Dessuten kan bbylen ved denne utfbrelse fremstilles av et tynnere materiale, hvilket innebærer en vektreduksjon som er av betydning når det gjelder bindinger for konkurransebruk. Anordnin-gen ifblge oppfinnelsen innebærer også at bindingen kan loses på enkel måte ved hjelp av en skistav, hvis spiss fores inn mellom krokens ben og kroken tvinges forover ut av inngrep med bbylen. By having a leg of the hook hold each half of the trailer, a better fastening is achieved, even if the trailer is loaded unevenly. In addition, with this design, the car can be made of a thinner material, which means a weight reduction that is important when it comes to bindings for competition use. The device according to the invention also means that the binding can be loosened in a simple way with the help of a ski pole, the tip of which is inserted between the legs of the hook and the hook is forced forwards out of engagement with the hook.

Partiene 17 er ved utfbrelses eksemp1et vist vinkelrette til bindingens midtplan, men disse partier kan også danne en vinkel mindre enn 90° med dette plan. I dette ti 1 fel 1e utfores kroken med nærmest V-formet tverrsnitt, således at krokens ben forblir i hovedsaken vinkelrette til vedkommende partier 17. The parts 17 are shown in the embodiment example perpendicular to the middle plane of the bond, but these parts can also form an angle of less than 90° with this plane. In this section 1e, the hook is made with an almost V-shaped cross-section, so that the leg of the hook remains essentially perpendicular to the parts 17 in question.

Ved den på fig. 3 og 4 viste utfbrelse er kroken og bbylen noe endret for også å muliggjbre fastspenning av bindingen ved bruk av skista v sp issen. Holderkroken 13' er forlenget med en del 19 som er så lang at den muliggjbr at kroken kan bli tilbake i bbylen ved bindingens lbsgjbring. På bbylens gripedel 16 er der anordnet en plate 20 som f. eks. er forbundet med bbylen med en smekkforbin-delse, således at den lett kan fjernes. Platens 20 bakre kant be-finner seg i en sådan avstand fra kroken 13' at denne har tilstrek-kelig plass til å svinge frem og la partiene 17 frigjbres fra haken, men ikke så meget at delens 19 for 1engedebakdel kan passere forbi bbylen. Platen 20 er hensiktsmessig utformet med en fordypning 21. Når bindingen skal spennes, trykkes stavens spiss mot fordyp-ningen 21, således at bbylen trykkes ned inntil kroken hakes fast i bbylen i en av dennes fordypninger. At the one in fig. In the version shown in 3 and 4, the hook and the hook have been slightly modified to also enable the binding to be tightened using the skid plate. The holder hook 13' is extended by a part 19 which is so long that it enables the hook to be left in the car when the binding is released. A plate 20 is arranged on the grip part 16 of the bicycle, which, for example, is connected to the car with a snap connection, so that it can be easily removed. The rear edge of the plate 20 is at such a distance from the hook 13' that it has sufficient space to swing forward and allow the parts 17 to be released from the hook, but not so much that the rear part of the part 19 can pass past the car. The plate 20 is suitably designed with an indentation 21. When the binding is to be tightened, the tip of the rod is pressed against the indentation 21, so that the hook is pressed down until the hook hooks into the indentation in one of its recesses.

Ved utfbrelsen ifblge fig. 5 og 6 er der mellom holder-krokens 13 to ben 18 rundt en aksel 22 som kroken er svingbart In the execution according to fig. 5 and 6 are there between the two legs 18 of the holder hook 13 around an axle 22 on which the hook is pivotable

lagret om, lagt en skrufjær 23, hvis ene ben 24 er bbyet ca. 90° til siden og ligger fjærende an mot tåbeslagets 10 vertikale, fremre kant, mens det annet ben 25 er bbyet oppad noe mindre enn 90° og ligger fjærende an mot krokens 30 i det vesentlige vertikale parti som står praktisk talt loddrett på bindingens langakse. Fjæren 23 har således en viss forspenning og trykker kroken 13 mot bbylens 12 ben 17, således at kroken, når gripedelen 16 trykkes ned, ikke av benene 17 kan svinges mot urviseren så langt at samvirket med bbylen 12 opphorer. Når bindingen skal lbsgjbres, innfores der f.eks. en stored again, added a coil spring 23, one leg 24 of which is bent approx. 90° to the side and rests resiliently against the vertical front edge of the toe fitting 10, while the other leg 25 is bent upwards somewhat less than 90° and lies resiliently against the essentially vertical part of the hook 30 which is practically vertical to the long axis of the binding. The spring 23 thus has a certain bias and presses the hook 13 against the legs 17 of the bbylen 12, so that the hook, when the gripping part 16 is pressed down, cannot be swung clockwise by the legs 17 so far that the cooperation with the bbylen 12 ceases. When the bond is to be loosened, e.g. one

stavspiss mellom krokens ben 18, hvoretter kroken svinges fremad mot fjærens virkning. rod tip between the hook's legs 18, after which the hook is swung forward against the action of the spring.

I stedet for en skrufjær 23 kan der anvendes en bladfjær, hvis ene ende er festet til tåbeslagets 10 fremre del og hvis annen ende ligger an mot kroken 13, således at denne tvinges i urviserens retning ifblge fig. 5. Ennvidere kan der som fjær anvendes en gummikloss eller lignende som monteres på tåbeslagets 10 horison-tale, fremadrettede forlengelse og trykker mot krokens 13 underside for å svinge denne i urviserens retning. Instead of a coil spring 23, a leaf spring can be used, one end of which is attached to the front part of the toe fitting 10 and the other end of which rests against the hook 13, so that it is forced in a clockwise direction according to fig. 5. Furthermore, a rubber block or the like can be used as a spring which is mounted on the horizontal, forward extension of the toe fitting 10 and presses against the underside of the hook 13 to swing it in a clockwise direction.
