Definitions
- the present invention relates to a pair of track skis with elongated tips, these skis being more particularly intended for competition, and especially for slalom races.
- each ski is equipped, at its front end, with an asymmetrical deflector, the profile of which extends that of the tip.
- the length of this deflector is small in order to prevent its front end from being too high with respect to the surface of the snow, to the detriment of its effectiveness.
- the pair of skis it relates to in which the front end of each ski is equipped with an asymmetrical deflector, the rear part of which is mounted at the end of the truncated tip of the ski, conforms to the profile of the latter, and whose front end comprises a point offset from the side of the other ski, relative to the longitudinal median plane of the equipped ski, is characterized in that the rear part of each diverter is extended by a front part which is in carrier overhang relative to the spatula truncated transversely and which is substantially parallel to the plane defined by the bearing area of the ski.
- deflectors are advantageous since, for the same length, that is to say for the same weight as the known deflectors, their active part is of greater length taking into account their orientation substantially parallel to the plane of the ski, this orientation favoring in in addition to the ability to deflect a ski when the deflector comes into contact with a slalom pole.
- FIGs 1 and 2 a ski for left foot.
- This ski which is a slalom ski, has an asymmetrical deflector 2, which is attached by gluing or by any other means on its tip 3 and which becomes thinner while being curved towards the other ski of the pair, a large part 5 of this deflector being in overhang relative to this spatula 3.
- the deflector 2 is pierced with holes 4, in order on the one hand to make it lighter, and on the other hand to improve its penetration into the air.
- the cantilever part 5 is substantially horizontal, its pointed end 6, however, rising slightly.
- the end, conventionally at a point, of the spatula 3 is truncated, this spatula having been previously sectioned along a transverse line 7.
- the rear part 8 of the diverter 2 precisely follows the top of the truncated end of the spatula 3, and this rear part 8 is progressively connected, at the level of the transverse line 7, to the substantially horizontal part 5.
- FIG. 3 shows a pair of skis 9, 10 produced in the same way as the ski according to FIGS. 1 and 2. These skis 9, 10 are therefore fitted with added deflectors 11, 12 which are each curved, in top view, towards the other ski of the same pair (respectively 10 and 9).
- the additional length, compared to the standard ski without deflector, conferred by a deflector such as 11, is referenced by L. Due to the flattened shape of the deflector 11, this supplement L is greater, for an equal amount of added material, to that conferred by an asymmetric deflector of known type whose curve extends that of the complete tip on which it is attached. The risk of getting on a slalom pole 13 is consequently reduced accordingly. Also due to the flattened shape of the deflector 11, the contact angle between this deflector and the stake is substantially a right angle, whereas with a traditional spatula or a known deflector, whose curve extends that of the spatula, this contact angle is around 45 degrees. This embodiment also contributes to limiting the risk of straddling the slalom stake 13.
- this deflector allows the ski to be engaged in the turn when the inside ski grips. By its flattened shape, it allows the ski to erase the stake more easily and consequently the skier to more easily evade it. The ski's turning trajectory is thus tighter and allows a higher speed of passage of the slalom gates.
- the elongated tip comprising this deflector, can be integrated into the structure of the ski during its production, for example by molding.

Abstract
Description
La présente invention se rapporte à une paire de skis de piste à spatules allongées, ces skis étant plus particulièrement destinés à la compétition, et surtout aux courses de slalom.The present invention relates to a pair of track skis with elongated tips, these skis being more particularly intended for competition, and especially for slalom races.
Au cours d'une course de slalom, le skieur est amené à franchir des portes délimitées chacune par deux piquets. Au cours d'un mauvais passage de porte, il risque d'enfourcher un des deux piquets et par suite de se blesser. Afin d'augmenter la sécurité du skieur tout en lui donnant plus de chances de franchir les portes du slalom, il est connu de rapporter, sur l'extrémité en pointe de la spatule du ski, une pièce courbe asymétrique qui prolonge cette spatule en rendant la pointe du ski dissymétrique en direction de l'autre ski d'une même paire. Cette pièce rapportée, souvent appelée "déviateur", a cependant pour inconvénient d'augmenter le poids du ski. Afin de pallier cet inconvénient, on est amené à réaliser des déviateurs relativement courts, de sorte que leur efficacité n'est pas optimale.During a slalom race, the skier is led to cross gates each delimited by two stakes. During a bad door passage, he risks straddling one of the two stakes and consequently injuring himself. In order to increase the safety of the skier while giving him more chances of crossing the doors of the slalom, it is known to add, on the point end of the ski tip, an asymmetrical curved piece which extends this tip by making the tip of the asymmetrical ski towards the other ski of the same pair. This added piece, often called a "deflector", has the disadvantage of increasing the weight of the ski. In order to overcome this drawback, it is necessary to produce relatively short deflectors, so that their efficiency is not optimal.
Tel est le cas notamment de la paire de skis décrite dans le document EP A 0 168 579, dans laquelle chaque ski est équipé, à son extrémité avant, d'un déviateur asymétrique, dont le profil prolonge celui de la spatule. De ce fait, la longueur de ce déviateur est faible afin d'éviter que son extrémité avant soit trop haute par rapport à la surface de la neige, au détriment de son efficacité.This is particularly the case for the pair of skis described in document EP A 0 168 579, in which each ski is equipped, at its front end, with an asymmetrical deflector, the profile of which extends that of the tip. As a result, the length of this deflector is small in order to prevent its front end from being too high with respect to the surface of the snow, to the detriment of its effectiveness.
L'invention vise à remédier à ces inconvénients. A cet effet, la paire de skis qu'elle concerne, dans laquelle l'extrémité avant de chaque ski est équipée d'un déviateur asymétrique dont la partie arrière montée en bout de la spatule tronquée du ski épouse le profil de celle-ci, et dont l'extrémité avant comporte une pointe décalée du côté de l'autre ski, par rapport au plan médian longitudinal du ski équipé, est caractérisée en ce que la partie arrière de chaque déviateur est prolongée par une partie avant qui est en porte-à-faux par rapport à la spatule tronquée transversalement et qui est sensiblement parallèle au plan défini par la zone portante du ski.The invention aims to remedy these drawbacks. To this end, the pair of skis it relates to, in which the front end of each ski is equipped with an asymmetrical deflector, the rear part of which is mounted at the end of the truncated tip of the ski, conforms to the profile of the latter, and whose front end comprises a point offset from the side of the other ski, relative to the longitudinal median plane of the equipped ski, is characterized in that the rear part of each diverter is extended by a front part which is in carrier overhang relative to the spatula truncated transversely and which is substantially parallel to the plane defined by the bearing area of the ski.
Ces déviateurs sont avantageux puisque, pour une même longueur, c'est-à-dire pour un même poids que les déviateurs connus, leur partie active est de longueur supérieure compte tenu de leur orientation sensiblement parallèle au plan du ski, cette orientation favorisant en outre la capacité de déviation d'un ski lorsque le déviateur vient au contact d'un piquet de slalom.These deflectors are advantageous since, for the same length, that is to say for the same weight as the known deflectors, their active part is of greater length taking into account their orientation substantially parallel to the plane of the ski, this orientation favoring in in addition to the ability to deflect a ski when the deflector comes into contact with a slalom pole.
D'autres caractéristiques de l'invention ressortent des revendications 2 à 5.Other characteristics of the invention appear from
De toute façon, l'invention sera bien comprise, et ses avantages et ses caractéristiques ressortiront, au cours de la description suivante d'un exemple non limitatif de réalisation de ce ski, en référence au dessin schématique annexé dans lequel:
- Figure 1 est une vue en perspective de la partie avant de ce ski;
- Figure 2 en est une vue latérale; et
- Figure 3 montre, vue de dessus, la partie avant d'une paire de skis de ce type.
- Figure 1 is a perspective view of the front part of this ski;
- Figure 2 is a side view; and
- Figure 3 shows, top view, the front part of a pair of skis of this type.
Aux figures 1 et 2 est représenté un ski pour pied gauche. Ce ski, qui est un ski de slalom, comporte un déviateur asymétrique 2, qui est rapporté par collage ou par tout autre moyen sur sa spatule 3 et qui va en s'amincissant tout en étant incurvé en direction de l'autre ski de la paire, une grande partie 5 de ce déviateur étant en porte-à-faux par rapport à cette spatule 3. Le déviateur 2 est percé de trous 4, afin d'une part de le rendre plus léger, et d'autre part d'améliorer sa pénétration dans l'air. La partie en porte-à-faux 5 est sensiblement horizontale, son extrémité en pointe 6 se relevant cependant légèrement.In Figures 1 and 2 is shown a ski for left foot. This ski, which is a slalom ski, has an
L'extrémité, classiquement en pointe, de la spatule 3 est tronquée, cette spatule ayant été préalablement sectionnée selon une ligne transversale 7. La partie arrière 8 du déviateur 2 épouse précisément le dessus de l'extrémité tronquée de la spatule 3, et cette partie arrière 8 se raccorde progressivement, au niveau de la ligne transversale 7, à la partie sensiblement horizontale 5.The end, conventionally at a point, of the
La figure 3 montre une paire de skis 9, 10 réalisés de la même manière que le ski selon les figures 1 et 2. Ces skis 9, 10 sont donc équipés de déviateurs rapportés 11, 12 qui sont chacun incurvés, en vue de dessus, en direction de l'autre ski de la même paire (respectivement 10 et 9).FIG. 3 shows a pair of
Le supplément de longueur, par rapport au ski standard sans déviateur, conféré par un déviateur tel que 11, est référencé par L. En raison de la forme aplatie du déviateur 11, ce supplément L est supérieur, pour une égale quantité de matière rapportée, à celui conféré par un déviateur asymétrique de type connu dont le galbe prolonge celui de la spatule complète sur laquelle il est rapporté. Le risque d'enfourcher un piquet de slalom 13 est par suite diminué d'autant. En raison également de la forme aplatie du déviateur 11, l'angle de contact entre ce déviateur et le piquet est sensiblement un angle droit, alors qu'avec une spatule traditionnelle ou un déviateur connu, dont le galbe prolonge celui de la spatule, cet angle de contact se situe vers 45 degrés. Ce mode de réalisation contribue également à limiter le risque d'enfourchement du piquet de slalom 13.The additional length, compared to the standard ski without deflector, conferred by a deflector such as 11, is referenced by L. Due to the flattened shape of the deflector 11, this supplement L is greater, for an equal amount of added material, to that conferred by an asymmetric deflector of known type whose curve extends that of the complete tip on which it is attached. The risk of getting on a
La longueur surbaissée de ce déviateur permet au ski d'être engagé dans le virage au moment de la prise de carre du ski intérieur. Par sa forme aplatie, il permet au ski d'effacer plus aisément le piquet et par suite au skieur de s'en dérober plus facilement. La trajectoire en virage du ski est ainsi plus serrée et permet une plus grande vitesse de passage des portes de slalom.The lowered length of this deflector allows the ski to be engaged in the turn when the inside ski grips. By its flattened shape, it allows the ski to erase the stake more easily and consequently the skier to more easily evade it. The ski's turning trajectory is thus tighter and allows a higher speed of passage of the slalom gates.
Au lieu d'être rapportée, la spatule allongée, comportant ce déviateur, peut être intégrée à la structure du ski lors de sa réalisation, par exemple par moulage.Instead of being attached, the elongated tip, comprising this deflector, can be integrated into the structure of the ski during its production, for example by molding.
