Description
Oppfinnelsen vedrører en fremgangsmåte for forbedring av festet for en ski med plastsåle, f.eks. en stemslipt ski med polyetensåle, og/eller for fremme av vedheftningen av festesmøringer uten vesentlig nedsettelse av skiens glideegenskaper. The invention relates to a method for improving the attachment for a ski with a plastic sole, e.g. a ground ski with a polyethylene sole, and/or to promote the adhesion of attachment lubricants without significantly reducing the ski's gliding properties.
Funksjonen av en skismøring baserer seg somThe function of a ski lubrication is based on
kjent på at snøkrystallenes skarpe kanter trenger inn i det plastiske eller elastiske flatesjikt som smøringen danner og derved tilveiebringer en høy hvilefriksjon, known for the fact that the sharp edges of the snow crystals penetrate the plastic or elastic surface layer formed by the lubrication and thereby provide a high resting friction,
som følge av hvilken skien får feste. Ettersom snestruk-turen varierer betydelig, trenges det forskjellige slags smøringer for forskjellige fører. Såvel smørte som usmørte ski glir på en tynn vannhinne som dannes når. snekrystallenes kanter smelter ved innvirkning av bevegelse sf riks j onen . as a result of which the ski gets attached. As the snow structure varies considerably, different types of lubrication are needed for different drivers. Both lubricated and unlubricated skis slide on a thin film of water that forms when the edges of the snow crystals melt under the influence of movement of the spheric ion.
Det er tidligere kjent forskjellige slags skisålekonstruksjoner med aktive eller passive partier som trenger inn i sneen og gir et mekanisk feste. Det er blant annet tidligere kjent å anvende en skisåle med skjellformet profilert flate. Skjellene danner hellende plan på hvilke skien glir. Skjellenes bakoverrettede vinkelrette trappetrinn forhindrer bakoverglidning og gir altså skien feste når sneen pakker seg bak disse. Different types of ski sole constructions with active or passive parts that penetrate the snow and provide a mechanical attachment are previously known. Among other things, it is previously known to use a ski sole with a shell-shaped profiled surface. The shells form inclined planes on which the ski slides. The shells' backwards perpendicular steps prevent sliding backwards and thus give the ski a grip when the snow packs up behind them.
Det er også tidligere kjent en hul- og trappe-trinnsåle hvis funksjon baserer seg på samme mekanisme, som skjellsålens funksjon, men hvis flate har negativ profilering. En slik såle gir bedre gli, men festet er dårligere enn det festet som oppnås med skjellsålen. Som eksempel på en slik konstruksjon vises til norsk patent nr. 89238. There is also previously known a hollow and stair step sole whose function is based on the same mechanism as the shell sole's function, but whose surface has negative profiling. Such a sole provides better gliding, but the grip is worse than the grip achieved with the shell sole. As an example of such a construction, reference is made to Norwegian patent no. 89238.
Det er også kjent forskjellige slags hårete skisåler som fremviser f.eks. syntetiske hårete strimler der hårene heller i glideretningen. I forbindelse med disse såler gir en bevegelse mot hårene feste til skien. Som eksempel på slike kjente såler vises til DE-utleg-ningsskrift nr. 1.144.165 og FI-patent nr. 43.401. Different types of hairy ski soles are also known which exhibit e.g. synthetic hairy strips where the hairs tend in the sliding direction. In connection with these soles, a movement against the hairs gives attachment to the ski. As an example of such known soles, reference is made to DE specification no. 1,144,165 and FI patent no. 43,401.
Det er også tidligere kjent skisåler av hård plast, f.eks. teflon, som karakteriseres ved en spesielt liten friksjonskoeffisient. Som eksempel på disse såler vises til US-patent nr. 2.908.506. I forbindelse med disse ski- er dog ikke problemet med feste, løst. There are also previously known ski soles made of hard plastic, e.g. teflon, which is characterized by a particularly low coefficient of friction. As an example of these soles, reference is made to US patent no. 2,908,506. In connection with these skis, however, the problem of attachment has not been solved.
Det er også tidligere kjent forskjellige slags skisålekonstruksjoner der man har forsøkt, å forbedre den for de fleste plastsåler karakteristiske dårlige smøre-vedhefting. Som eksempel på disse- vises til søkerens US-patent nr. 3.897.074. Gjennom dette patentskrift er det kjent å overflatebehandle skisålen, i dette tilfellet å slipe skisålen, slik at sålen får en loet flate som gir glid. Various types of ski sole constructions have also previously been known in which attempts have been made to improve the poor lubrication adhesion characteristic of most plastic soles. As an example of this, reference is made to the applicant's US patent no. 3,897,074. Through this patent document, it is known to surface treat the ski sole, in this case to grind the ski sole, so that the sole has a smooth surface that provides glide.
Det er også tidligere kjent enten bånd- eller stenslipeski med plastsåler. Disse ski har den fordel at de glir relativt bra, men for å tilveiebringe feste er det nødvendig å anvende smøring. It is also previously known either belt or stone grinding skis with plastic soles. These skis have the advantage that they glide relatively well, but to provide grip it is necessary to apply lubrication.
Formålet med den foreliggende oppfinnelse er å tilveiebringe en enkel fremgangsmåte for å forbedre festet for ski med plastsåle generelt og for ski med stenslipt plastsåle spesielt og/eller for å fremme vedheftingen av festesmøring. For oppnåelse av dette mål er fremgangsmåten ifølge oppfinnelsen hovedsakeligkarakterisert vedat flaten av skiens plastsåle oksyderes, f.eks. flammebehandles. The purpose of the present invention is to provide a simple method for improving the attachment for skis with plastic soles in general and for skis with stone-ground plastic soles in particular and/or for promoting the adhesion of attachment lubrication. To achieve this goal, the method according to the invention is mainly characterized by the fact that the surface of the ski's plastic sole is oxidised, e.g. flame treated.
Oppfinnelsen skal i det følgende beskrives mer detaljert med henvisning til en utførelsesform som er vist i tegningens figurer. Oppfinnelsen er dog ikke på noe vis strengt begrenset til denne utførelsesform. In the following, the invention will be described in more detail with reference to an embodiment shown in the figures of the drawing. However, the invention is in no way strictly limited to this embodiment.
Fig. 1 viser en ski sett nedenfra som er behandlet ifølge fremgangsmåten i den foreliggende oppfinnelse, Fig. 1 shows a ski seen from below which has been treated according to the method of the present invention,
fig. 2 viser samme ski sett fra siden, ogfig. 2 shows the same ski seen from the side, and
fig. 3 viser et snitt III-III i fig. 2 i større målestokk. fig. 3 shows a section III-III in fig. 2 on a larger scale.
Den i tegningsfigurene viste ski 10 er forsynt med et styrespor 13 og en plastsåle 14. Skiens tupp er angitt med henvisningsta Het 11 og skiens bakre ende med henvisningstallet 12. Av snittet i fig. 3 fremgår i større detalj, skiens 10 konstruksjon. Fig. 3 viser plastsålen 14 og sjikt 15 og 16 av armert plast som gir skien styrke. Mellom sjiktene 15 og 16 finnes et mellomsjikt 17 av porøs plast. The ski 10 shown in the drawings is provided with a guide track 13 and a plastic sole 14. The tip of the ski is indicated with the reference number Het 11 and the rear end of the ski with the reference number 12. From the section in fig. 3 shows in greater detail the construction of the ski 10. Fig. 3 shows the plastic sole 14 and layers 15 and 16 of reinforced plastic which give the ski strength. Between the layers 15 and 16 there is an intermediate layer 17 of porous plastic.
Den i figurene viste skis plastsåle 14 er f.eks. stenslipt og fremviser altså en viss, for stensliping karakteristisk profil. Skisålens plastmateriale flammebehandles, f.eks. med flammer fra flytende gass eller lig-nende, innen skiens festeområde 18.. Ved en slik be-handling endres plastens og dens overflates egenskaper på en slik måte at adhesjonen mellom sålematerialet og The plastic sole 14 of the ski shown in the figures is e.g. stone ground and thus presents a certain profile characteristic of stone grinding. The plastic material of the ski sole is flame treated, e.g. with flames from liquid gas or the like, within the ski's attachment area 18. With such treatment, the properties of the plastic and its surface are changed in such a way that the adhesion between the sole material and
sneen øker vesentlig innen området 18. Det er konstatert at det på denne måte frembragte festet for skien ikke nedsetter gliegenskapene, i det minste ikke i nevneverdig grad, men at det i stedet oppnås et optimalt resultat med hensyn til gli og feste. Innen området 18 kan festet forbedres med i og for seg kjente festesmøringer. Flammebehandlingen ifølge oppfinnelsen har vist seg å være anvendbar endog i denne forbindelse, dog har det fremgått at behandlingen fremmer betydelig vedheftingen av smøringen på skiens sålemateriale. the snow increases significantly within area 18. It has been established that the mount for the ski produced in this way does not reduce the gliding properties, at least not to an appreciable extent, but that instead an optimal result is achieved with regard to gliding and mounting. Within the area 18, the attachment can be improved with attachment lubricants known per se. The flame treatment according to the invention has proven to be applicable even in this connection, however, it has emerged that the treatment significantly promotes the adhesion of the lubrication to the sole material of the ski.
I forbindelse med oppfinnelsen er det konstatert at den tidligere slette flate av skiens plastsåle, f.eks. flaten av en polyetensåle, når den oksyderes ved flamme-behandling, syrebehandling eller annen oksydasjonsbe-handling, blir matt og at dens festeegenskaper blir bedre uten at glien av den grunn blir vesentlig dårligere. Ettersom glien i det minste ikke blir vesentlig mindre på grunn av oksydasjonsbehandlingen ifølge oppfinnelsen, kan oksydasjonsbehandlingen i visse tilfeller utføres over skisålens hele lengde. .Det har vist seg at oppfinnelsen kan tilpasses spesielt fordelaktig på stenslipte skisåler. Stensliping gir skisålen en spesiell bunnprofil som kjennetegnes av fordypninger som hovedsakelig har form av en langstrakt ellipse hvis lengste akse er parallell med skien. Disse fordypninger er dypest ved midtpunktene. Denne bunnprofil nedsetter ikke skiens gli. Det er dessuten klart at det mekaniske festet som bunnprofilen gir, forbedres av det festet som tilveiebringes ved hjelp av oksydasjonsbe- • handlingen ifølge oppfinnelsen og som baserer seg på flatefysikalske fenomen. Herved oppnås en spesielt for-" delaktig plastsåle. In connection with the invention, it has been established that the previously smooth surface of the ski's plastic sole, e.g. the surface of a polyethylene sole, when it is oxidized by flame treatment, acid treatment or other oxidation treatment, becomes matte and that its adhesion properties are improved without the gliding being significantly impaired for that reason. As the slip at least does not become significantly smaller due to the oxidation treatment according to the invention, the oxidation treatment can in certain cases be carried out over the entire length of the ski sole. .It has been shown that the invention can be adapted particularly advantageously to stone-ground ski soles. Stone grinding gives the ski sole a special bottom profile that is characterized by depressions that mainly take the form of an elongated ellipse whose longest axis is parallel to the ski. These depressions are deepest at the midpoints. This bottom profile does not reduce the glide of the ski. It is also clear that the mechanical attachment provided by the bottom profile is improved by the attachment provided by means of the oxidation treatment according to the invention and which is based on surface physical phenomena. This results in a particularly advantageous plastic sole.
Oppfinnelsens forskjellige detaljer kan varieres innen rammen for den i de etterfølgende krav definerte oppfinnelsestanken. The various details of the invention can be varied within the scope of the inventive idea defined in the subsequent claims.
