Abstract
Ski (2) med fleksibel underside (8) som er forbundet med, og styres av, skiskoens (1) vertikale rotasjonsbevegelse. Denne bevegelsen overføres til den fleksible underside (8), ved hjelp av en hengslet skofesteanordning (3), som igjen beveger et overføringsstag (4), som igjen beveger vippearmer (5), som igjen beveger den fleksible underside (8) i vertikalplanet. Vippearmenes (5) bevegelser overføres til den fleksible underside (8) gjennom en kile og trykkfordeler (7), som er bevegelig og justerbar i skiens lengderetning. Skisko og skofesteanordning sammenføyes eller frigjøres, med en horisontal rotasjonsbevegelse, der festehoder (9) griper inn i motsvarende hull med låsespor(11).Ski (2) with flexible underside (8) associated with, and controlled by, the vertical rotation movement of the ski shoe (1). This movement is transmitted to the flexible underside (8), by means of a hinged shoe fastener (3), which in turn moves a transfer rod (4), which in turn moves the rocker arms (5), which in turn moves the flexible underside (8) in the vertical plane. The movements of the rocker arms (5) are transmitted to the flexible underside (8) through a wedge and pressure distributor (7), which is movable and adjustable in the longitudinal direction of the ski. The ski shoe and shoe mounting device are joined or released, with a horizontal rotary movement, where the mounting heads (9) engage in corresponding holes with locking grooves (11).
Description
Oppfinnelsen angår ski med fleksibel underside i festesonen, til bruk ved klassisk skigåing. The invention relates to skis with a flexible underside in the attachment zone, for use in classic skiing.
For mange skiforhold er det ofte vanskelig å finne det beste forhold mellom skienes glifunksjon og skienes festefunksjon i forhold til underlaget. Vanlige problemer er at skiene glir for dårlig, eller at de får for lite feste til underlaget, slik at frasparket mister efekt. For many skiing conditions, it is often difficult to find the best relationship between the skis' gliding function and the skis' fastening function in relation to the surface. Common problems are that the skis slide too poorly, or that they get too little grip on the ground, so that the kick-off loses its effect.
Det har tidligere vært foreslått å lage ski, i den hensikt å forbedre gli og feste i forhold til underlaget. En slik ski er tidligere beskrevet i pat.nr. 309928» ski med opphøyet festeflate» og i EP 2295120 (A1)» ski, in particular cross-country ski with at least one device to prevent slipping backwards». It has previously been proposed to make skis, with the intention of improving gliding and grip in relation to the surface. Such a ski has previously been described in patent no. 309928" ski with raised attachment surface" and in EP 2295120 (A1)" ski, in particular cross-country ski with at least one device to prevent slipping backwards".
Med tradisjonelle ski søker brukeren å få skien til å feste til underlaget, ved å overføre vekt til kun den ski som det skal sparkes fra med, for derved å presse festesonen ned mot underlaget som igjen skaper friksjon for fraspark. With traditional skis, the user seeks to get the ski to stick to the ground, by transferring weight to only the ski that is to be kicked from, thereby pressing the attachment zone down against the ground, which in turn creates friction for kicking off.
Når bruker av tradisjonelle ski har vekten fordelt på to ski, vil festesonen på skiene ikke presses ned mot underlaget og skiene vil gli på glidesonene som utgjør skienes fremre og bakre undersider. When the user of traditional skis has his weight distributed over two skis, the attachment zone of the skis will not be pressed down against the ground and the skis will slide on the sliding zones that make up the front and rear undersides of the skis.
I følge oppfinnelsen, ski med fleksibel underside i festesonen, oppnås at denne del av skien presses ned til en konveks form ved fraspark, som igjen gir økt friksjon mot underlaget Ved glistadiet, vil den fleksible undersiden i festesonen, løftes opp til en konkav form, som vil minske friksjonen mot underlaget. According to the invention, skis with a flexible underside in the attachment zone, it is achieved that this part of the ski is pressed down into a convex shape during kick-off, which in turn gives increased friction against the ground During the gliding stage, the flexible underside in the attachment zone will be lifted up into a concave shape, which will reduce friction against the surface.
Dette oppnås i følge oppfinnelsen, ved at skiens fleksible underside i festesonen, er forbundet med skiskoens underside ved hjelp av vippearmer festet til skiens sider. Skiskoenes vertikale rotasjonsbevegelser overføres til skofesteanordningen. Skofesteanordningen beveger overføringsstag, som igjen beveger vippearmer. Når skiskoen, ved vippearmer og overføringsstag, ikke presser den fleksible undersiden ned til konveks form, holdes den fleksible undersiden opp fra underlaget i en konkav form ved hjelp av returfjærer. According to the invention, this is achieved by the fact that the flexible underside of the ski in the attachment zone is connected to the underside of the ski boot by means of rocker arms attached to the sides of the ski. The vertical rotational movements of the ski boots are transferred to the boot attachment device. The shoe attachment moves transfer rods, which in turn move rocker arms. When the ski boot, by rocker arms and transfer rods, does not press the flexible underside down into a convex shape, the flexible underside is held up from the ground in a concave shape by means of return springs.
For ytterligere å øke effekten av den fleksible underside, legges det en bevegelig og justerbar kile mellom vippearmer og den fleksible undersiden. Denne kilen kan beveges i skiens lengderetning med skruanordning, for å gjøre skien mer konveks eller mer konkav ut fra ønsket forhold mellom feste og gli. Kilen vil også fordele trykk fra vippearmer, over på skiens fleksible underside. To further increase the effect of the flexible underside, a movable and adjustable wedge is placed between the rocker arms and the flexible underside. This wedge can be moved in the lengthwise direction of the ski with a screw device, to make the ski more convex or more concave based on the desired ratio between grip and glide. The wedge will also distribute pressure from rocker arms onto the ski's flexible underside.
Ski med fleksibel underside ifølge oppfinnelsen er vist på tegninger 1-6. Skis with a flexible underside according to the invention are shown in drawings 1-6.
Figur 1 er et sideriss av skien (2), der midtre del av skiens underside er frigjort fra skien for å kunne være fleksibel i vertikalplanet. Figure 1 is a side view of the ski (2), where the middle part of the underside of the ski is freed from the ski in order to be flexible in the vertical plane.
Figur 2 er et sideriss av skien der de enkelte deler er skjematisk markert. Figure 2 is a side view of the ski where the individual parts are schematically marked.
Skiskoen (1) er festet til skiens (2) hengslede skofesteanordning (3). Oveføringsstag (4) er festet til skofesteanordningens (3) bakre bevegelige del samt til vippearmer (5), med beveglighet i festepunkter. Vippearmer (5) er festet til skiens side gjennom akslingspunkt (6). Vippearmene (5) treffer bevegelig kile og trykkfordeler (7) som igjen presser den fleksible undersiden (8) til konveks form. The ski boot (1) is attached to the ski's (2) hinged boot fastening device (3). The upper guide rod (4) is attached to the rear movable part of the shoe attachment device (3) and to the rocker arms (5), with movement in attachment points. Rocker arms (5) are attached to the side of the ski through pivot point (6). The rocker arms (5) hit the movable wedge and pressure distributor (7) which in turn pushes the flexible underside (8) into a convex shape.
Fleksibelt materiale dekker åpen spalte, mellom ski (2) og fleksibel underside (8), for å hindre inntrenging av fremmed elementer. Figur 3 er et sideriss av skien (2) der skiskoen (1) står med hele skoen nede på skien, og skiens fleksible underside (8) er konkav. Figur 4 er et sideriss av skien (2) der skiskoen (1) har rotert vertikalt fra skien gjennom skofesteanordningen (3), og skiens fleksible underside (8) er konveks. Figur 5 er et planriss av skofesteanordningens (3) bevegelige del, og motsvarende del under skisko, der sentrert styrepinne (10) treffer motsvarende hull (12). Opphøyede festehoder (9) passer overens med, og griper inn i, hull med låsespor (11). Figur 6 er et sideriss av skofesteanordningens (3) bevegelige del og motsvarende del under skisko. Flexible material covers the open gap, between the ski (2) and the flexible underside (8), to prevent the penetration of foreign elements. Figure 3 is a side view of the ski (2) where the ski boot (1) stands with the entire boot down on the ski, and the ski's flexible underside (8) is concave. Figure 4 is a side view of the ski (2) where the ski boot (1) has rotated vertically from the ski through the boot attachment device (3), and the ski's flexible underside (8) is convex. Figure 5 is a plan view of the moving part of the shoe attachment device (3), and the corresponding part under the ski boot, where the centered guide pin (10) hits the corresponding hole (12). Raised fastener heads (9) match, and engage, holes with locking grooves (11). Figure 6 is a side view of the shoe attachment device (3)'s movable part and the corresponding part under ski boots.
