Description
Foreliggende oppfinnelse angår en videreutvikling av plastsåle for ski ifølge norsk patent nr. 140 091 (norsk patentsøknad nr. 77.0004) som angitt i ingressen til det etterfølgende patentkrav 1. The present invention relates to a further development of a plastic sole for skis according to Norwegian patent no. 140 091 (Norwegian patent application no. 77.0004) as stated in the preamble to subsequent patent claim 1.
Skisålen ifølge nevnte patent består av et komposittmate-riale som er bygget opp av en matriks med innleirede relativt hårdere, skråttstilte legemer, slik at matriksen og legemene under slitasje av skisålen fører til en vekslende, tredimensjonalt mønstret glideflate med ensrettet retningsavhengig friksjonskoeffisient gjennom sålens brukstid. Ifølge tilleggspatent nr. (søknad nr. 78. 0006) kan disse legemene foruten å være skråttstilte, også være horisontalstilte, hvorved skisålen blir ekstremt slitesterk, dog uten at friksjon mot sne blir vesentlig forskjellig i glidefasen og ved fraspark. The ski sole according to the aforementioned patent consists of a composite material which is built up from a matrix with embedded relatively harder, inclined bodies, so that the matrix and the bodies during wear of the ski sole lead to an alternating, three-dimensionally patterned sliding surface with a unidirectional direction-dependent friction coefficient throughout the sole's lifetime. According to supplementary patent no. (application no. 78. 0006), these bodies can, in addition to being inclined, also be horizontal, whereby the ski sole becomes extremely durable, although without the friction against snow being significantly different in the sliding phase and during kick-off.
I ovennevnte tilleggspatent er det i forbindelse med prob-lemer vedrørende statisk elektrisitet på kaldt og tørt føre, nevnt at det i områdene rundt de innleirede hårdere legemene In the above-mentioned additional patent, in connection with problems regarding static electricity on cold and dry roads, it is mentioned that in the areas around the embedded harder bodies
dannes en bust av plastmatriksen som forårsakes av sliping eller slitasje. I denne forbindelse er det i tilleggspatentet konstatert at nevnte bust under vanlige føreforhold ligger langs såle-flaten i glifasen, og reises/vendes ved fraspark uten at glide-egenskapene påvirkes i uheldig grad. Denne bust består av opp-flisete fiberender av termoplast. a bristle is formed from the plastic matrix caused by grinding or wear. In this connection, it has been established in the supplementary patent that said bristle under normal driving conditions lies along the sole surface in the gliding phase, and is raised/turned when kicking off without the gliding properties being adversely affected. This bristle consists of split fiber ends of thermoplastic.
Under fortsatte forsøk og relativt omfattende bruk av skisålen ifølge ovennevnte norske patenter, har det vist seg at denne busten i kombinasjon med de skråttstilte legemene, bevir-ker det gode festet ved fraspark. Videre er konstatert at busten er av vesentlig betydning for skisålens retningsavhengige friksjonskoeffisient. Ennvidere er konstatert at de skråttstilte legemene bidrar til å nedsette glien, særlig på svært kaldt og svært vått føre, noe som i praksis er blitt motvirket ved å polere bort mikromønsteret under skiens for- og bakparti. During continued trials and relatively extensive use of the ski sole according to the above-mentioned Norwegian patents, it has been shown that this bristle, in combination with the inclined bodies, causes the good hold when kicking off. Furthermore, it has been established that the bristles are of significant importance for the direction-dependent friction coefficient of the ski sole. Furthermore, it has been established that the inclined bodies contribute to reducing sliding, especially on very cold and very wet roads, which in practice has been countered by polishing away the micro-pattern under the front and rear of the ski.
Formålet med foreliggende oppfinnelse er å dra nytte av nevnte bust i størst mulig grad på bekostning av de innleirede partiklene som dog forutsettes å måtte være til stede, da denne bust dannes i grensesonene mellom legemene og matriksen. The purpose of the present invention is to take advantage of said bristle to the greatest possible extent at the expense of the embedded particles which, however, are assumed to be present, as this bristle is formed in the boundary zones between the bodies and the matrix.
Ifølge foreliggende oppfinnelse er dette oppnådd ved en skisåle av den innledningsvis angitte art, med de nye trekk som er angitt i karakteristikken til det etterfølgende krav 1. According to the present invention, this has been achieved by a ski sole of the type indicated at the outset, with the new features that are indicated in the characteristic of the subsequent claim 1.
Ved bruk av horisontalstilte legemer kan riktig retnings-orientert bust dannes ved sliping. Denne retningsorienterte bust vil imidlertid bare ha en tidsbegrenset enerådende effekt, idet bust som er motsatt rettet vil dannes etter en tids bruk av skiene, og i tillegg vil slitasjen føre til en polering av sålen og busten forsvinner. Slike ski vil derfor bare være av interesse for spesialanvendelser, mens skråttstilte, relativt myke legemer vil dominere i denne henseende. When using horizontally oriented bodies, correctly oriented bristles can be formed by grinding. However, this directional bristle will only have a time-limited dominant effect, as bristles that are oppositely directed will form after a period of use of the skis, and in addition the wear will lead to a polishing of the sole and the bristles will disappear. Such skis will therefore only be of interest for special applications, while inclined, relatively soft bodies will dominate in this respect.
Disse legemene kan skråstilles i matriksen ved esktrude-ring eller kalandrering som angitt i ovenfor nevnte norske patenter. I denne forbindelse må imidlertid legemene være noe mer varmebestandige enn matriksmaterialet for at de skal kunne beholde sin form under sålens forgivning. For øvrig skal legemene bestå av et materiale som er mest mulig likt matriksmaterialet, dvs. de skal bl.a. være hydrofobe. These bodies can be inclined in the matrix by extrusion or calendering as indicated in the above-mentioned Norwegian patents. In this connection, however, the bodies must be somewhat more heat-resistant than the matrix material in order for them to be able to retain their shape during the deformation of the sole. Otherwise, the bodies must consist of a material that is as similar as possible to the matrix material, i.e. they must i.a. be hydrophobic.
En termoplast med høyere varmebestandighet enn egnet matriksmateriale, kan f.eks. være en tverrbundet termoplast. A thermoplastic with higher heat resistance than suitable matrix material, can e.g. be a cross-linked thermoplastic.
Et slikt materiale kan oppnås ved radioaktiv bestråling av f.eks. polyetylen, hvorved materialet blir mer formbestandig ved forholdsvis høyere temperatur uten at hårdheten og slitasje-egenskapene blir vesentlig endret. Such a material can be obtained by radioactive irradiation of e.g. polyethylene, whereby the material becomes more dimensionally stable at a relatively higher temperature without the hardness and wear properties being significantly changed.
Legemene kan også bestå av en termoplast med tetthet og molvekt som er noe forskjellig fra matriksmaterialet, hvorved bindingsforholdet mellom matriks og de innleirede legemene resulterer i endrede slitasjeegenskaper i grensesonene mellom disse. The bodies can also consist of a thermoplastic with a density and molecular weight that is somewhat different from the matrix material, whereby the bonding relationship between the matrix and the embedded bodies results in changed wear properties in the boundary zones between them.
Skisålen ifølge foreliggende oppfinnelse kan til en viss grad sammenlignes med tidligere kjente skisåler med pålimt na-turlig eller kunstig pels. Den bust det i foreliggende til-felle er tale om, vil på samme vis som pels, ligge langs såle-flaten i glidefasen og reises/vendes ved fraspark. Denne busten er imidlertid finere og kortere enn pels og ligger i glidefasen ikke bare langs, men også innfelt i sålen. Lugging i løypa vil derfor ikke forekomme. En annen betydelig fordel med skisålen ifølge foreliggende oppfinnelse, er at busten vil fornye seg selv og derfor være til stede i sålens levetid. The ski sole according to the present invention can be compared to a certain extent with previously known ski soles with glued-on natural or artificial fur. The bristles in question in the present case will, in the same way as fur, lie along the sole surface in the sliding phase and be raised/turned when kicking off. However, this bristle is finer and shorter than fur and in the sliding phase lies not only along, but also embedded in the sole. Lugging on the trail will therefore not occur. Another significant advantage of the ski sole according to the present invention is that the bristles will renew themselves and therefore be present during the lifetime of the sole.
