Description

L'invention a pour object un nouveau ski permet­tant d'améliorer l'apprentissage et la pratique de ce sport.The object of the invention is a new ski which makes it possible to improve the learning and the practice of this sport.

L'invention concerne plus spécialement un ski polyvalent incluant un noyau d'appui forme par un corps allongé qui s'étend sur pratiquement toute la longueur du ski constitué par un corps médian et deux parties avant et arrière et d'une enveloppe entourant le noyau d'appui.The invention relates more particularly to a multi-purpose ski including a support core formed by an elongated body which extends over practically the entire length of the ski consisting of a median body and two front and rear parts and of an envelope surrounding the core support.

On sait que la position du skieur au cours de son mouvement de glisse est essentiellement caractérisée par une certaine angulation des segments des ensembles inférieurs et par une détente musculaire, susceptibles de permettre au skieur d'absorber en souplesse les inégalités de la surface du terrain d'évolution.It is known that the position of the skier during his gliding movement is essentially characterized by a certain angulation of the segments of the lower assemblies and by muscular relaxation, capable of allowing the skier to flexibly absorb the unevenness of the surface of the terrain. 'evolution.

En étudiant le problème posé par la recherche par le skieur d'une position lui permettant de maintenir son équilibre, l'inventeur a constaté que la réalisation de skis selon une configuration particulière permet d'éliminer au moins une grande partie des inconvénients résultant de l'utilisation de skis de l'art antérieur.By studying the problem posed by the skier's search for a position enabling him to maintain his balance, the inventor has found that the production of skis according to a particular configuration makes it possible to eliminate at least a large part of the drawbacks resulting from the use of prior art skis.

L'invention a donc pour but de fournir un ski de type indiqué ci-dessus dont la forme spécifique permet au skieur de contrôler sa position pendant sa descente.The invention therefore aims to provide a ski of the type indicated above whose specific shape allows the skier to control his position during his descent.

L'invention a plus particulièrement pour objet un ski de ce type dont les extrémités avant et arrière sont relevées ce qui réduit considérablement les risques de chute, tout en favorisant la maniabilité du ski indé­pendamment des caractéristiques de la neige.The invention more particularly relates to a ski of this type, the front and rear ends of which are raised, which considerably reduces the risk of falling, while promoting the maneuverability of the ski independently of the characteristics of the snow.

L'invention a également pour objet un ski court et performant convenant aux alpinistes dont la sûreté d'emploi en virage réduit les risques de chute et d'acci­dent.The invention also relates to a short and efficient ski suitable for mountaineers whose safety of use in turns reduces the risk of fall and accident.

Conformément à l'invention, les parties avant et arrière relevées du ski possèdent une configuration trapézoïdale dont les petites bases constituent respecti­vement le bord d'attaque de la neige et le talon arrière et dont les grandes bases sont raccordées au corps médian.According to the invention, the raised front and rear parts of the ski have a trapezoidal configuration whose small bases respectively constitute the leading edge of the snow and the rear heel and whose large bases are connected to the median body.

Le ski ainsi réalisé présente de manière avan­tageuse une épaisseur continuellement décroissante de l'avant jusqu'à la zone de raccordement avec le corps médian. L'épaisseur maximale du ski est située à l'extré­mité arrière, cette épaisseur allant en augmentant par ailleurs de l'avant vers l'arrière.The ski thus produced advantageously has a continuously decreasing thickness from the front to the zone of connection with the median body. The maximum thickness of the ski is located at the rear end, this thickness also increasing from front to rear.

Les essais de skis de 60 à 90 cm répondant aux caractéristiques de forme précitées ont, en effet, démontré que le skieur était correctement supporté dans d'excellentes conditions d'adhérence et que la précision de freinage consécutive au déplacement ou à l'inclinaison transversale du ski étaient grandement améliorées.The tests of skis from 60 to 90 cm meeting the aforementioned shape characteristics have, in fact, demonstrated that the skier was correctly supported under excellent grip conditions and that the braking precision following displacement or transverse inclination skiing were greatly improved.

Par ailleurs, il a été constaté que le buste du skieur prenait automatiquement une position centrée par rapport au ski, favorable au maintien de celui-ci en équilibre et à la réalisation de l'aplomb indispensable à la pratique et au bon apprentissage du ski.Furthermore, it was found that the skier's bust automatically took a centered position relative to the ski, favorable for keeping the latter in balance and achieving the balance necessary for the practice and good learning of skiing.

L'utilisateur pourra, par voie de conséquence, améliorer ses conditions d'évolution en terrain accidenté, fortes pentes ou dans la pratique du ski acro­batique et artistique.The user will be able, consequently, to improve his conditions of evolution in rough terrain, steep slopes or in the practice of freestyle and artistic skiing.

D'autres caractéristiques et avantages du ski ressortiront de la description qui suit d'un exemple de réalisation de celui-ci en référence au dessin annexé dans lequel :

  • - la figure 1 est une vue en élévation du ski sur lequel a été représenté schématiquement une chaussure retenue par un dispositif de fixation,
  • - la figure 2 est une vue de dessus du ski,
  • - la figure 3 est une vue en perspective du ski représenté en position inclinée montrant la semelle rainurée de celui-ci,
  • - la figure 4 est une vue en coupe transversale du ski dans le plan 4-4 de la figure 2.
Other characteristics and advantages of the ski will emerge from the following description of an exemplary embodiment thereof with reference to the appended drawing in which:
  • FIG. 1 is an elevation view of the ski on which a shoe has been shown diagrammatically retained by a fastening device,
  • FIG. 2 is a top view of the ski,
  • - Figure 3 is a perspective view of the ski shown in an inclined position showing the grooved sole thereof,
  • FIG. 4 is a cross-sectional view of the ski in plane 4-4 of FIG. 2.

En se référant à la figure 1, le ski représenté est constitué par un corps allongé 1 rectiligne à bords 2 parallèles le long de la surface portante du ski qui se prolonge vers l'avant et vers l'arrière par des parties 3, 4 relevées dont l'inclinaison est comprise entre 15 et 30°.Referring to Figure 1, the ski shown is constituted by an elongated body 1 straight with edges 2 parallel along the bearing surface of the ski which is extended forward and backward by parts 3, 4 raised whose inclination is between 15 and 30 °.

Les parties avant 3 et arrière 4 se raccordent respectivement au corps 1 et l'ensemble est enrobé d'une enveloppe 6 à base de différentes résines synthétiques.The front 3 and rear 4 parts are respectively connected to the body 1 and the assembly is coated with a casing 6 based on different synthetic resins.

Comme le montre la figure 1, la zone d'appui du talon de la chaussure est située dans la zone de raccor­dement de la partie arrière 4 au corps 1 du ski ce qui permet d'obliger le skieur à maintenir une position natu­relle pour la pratique du ski.As shown in Figure 1, the support area of the heel of the boot is located in the connection area of the rear part 4 to the body 1 of the ski, which makes it possible to force the skier to maintain a natural position for the practice ski.

Les parties avant et arrière 3, 4 possèdent une configuration trapézoïdale dont les petites bases 3a, 4a constituent respectivement le bord d'attaque de la neige et le talon arrière tandis que les grandes bases sont raccordées au corps 1. Toutefois, la partie avant 3 ou spatule pourrait tout aussi bien avoir une forme arrondie d'aspect conventionnel.The front and rear parts 3, 4 have a trapezoidal configuration, the small bases 3a, 4a respectively constitute the leading edge of the snow and the rear heel while the large bases are connected to the body 1. However, the front part 3 or spatula could just as easily have a rounded shape with a conventional appearance.

Les parties 3 et 4 du ski possèderont de ce fait la même structure que l'enveloppe 6.The parts 3 and 4 of the ski will therefore have the same structure as the casing 6.

A titre d'exemple, le rapport des longueurs a, b des parties avant 3 et arrière 4 est compris entre 1,5 et 2 tandis que la largeur C du ski est sensiblement égale à la longueur b de la partie arrière 4.By way of example, the ratio of the lengths a, b of the front 3 and rear 4 parts is between 1.5 and 2 while the width C of the ski is substantially equal to the length b of the rear part 4.

Dans le but de favoriser le fléchissement naturel du skieur, l'épaisseur e de l'enveloppe 6 dans la zone du corps 1 est continuellement croissante de l'avant vers l'arrière du ski et possède une épaisseur maximale dans la zone correspondant au talon arrière. Par contre, l'épaisseur de la partie avant 3 est continuellement décroissante de l'extrémité avant jusqu'à la zone de rac­cordement avec le corps 1. L'avant du ski plus mince est donc plus souple et joue favorablement le rôle d'amortis­seur.In order to promote the natural deflection of the skier, the thickness e of the envelope 6 in the area of the body 1 is continuously increasing from the front to the rear of the ski and has a maximum thickness in the area corresponding to the rear heel. On the other hand, the thickness of the front part 3 is continuously decreasing from the front end to the zone of connection with the body 1. The front of the thinner ski is therefore more flexible and plays the role of shock absorber favorably. .

On réalise de la sorte un ski dont la rigidité de l'extrémité arrière est suffisante à l'évolution du ski en toute neige avec une adhérence améliorée.This produces a ski whose rigidity of the rear end is sufficient for the evolution of the ski in all snow with improved grip.

Nous décrivons maintenant la structure interne du ski en référence à la figure 4.We now describe the internal structure of the ski with reference to Figure 4.

A titre d'exemple, le noyau d'appui allongé est à base de bois et pourra être constitué par une âme 7 de latté frêne ventilée d'épaisseur constante.By way of example, the elongated support core is based on wood and may be constituted by a core 7 of ventilated ash blockboard of constant thickness.

L'âme 7 se termine aux extrémités avant et arrière des parties 3, 4. L'âme 7, qui peut être au besoin renforcée contient ainsi des canaux 9 bouchés destinés à procurer l'allègement et l'élasticité du ski. A cet effet, le noyau d'appui est constitué par une plu­ralité de baguettes 8 réparties en une nappe suivant la largeur du ski et séparées entr'elles par les canaux 9. Les différentes baguettes 8 sont réunies par des armatures 10 chargées à titre d'exemple par des fibres de carbone qui bouchent les extrémités des canaux 9.The core 7 ends at the front and rear ends of the parts 3, 4. The core 7, which can be reinforced if necessary, thus contains blocked channels 9 intended to provide the lightening and the elasticity of the ski. To this end, the support core is constituted by a plurality of rods 8 distributed in a sheet along the width of the ski and separated between them by the channels 9. The various rods 8 are joined by reinforcements 10 loaded as for example by carbon fibers which block the ends of the channels 9.

L'enveloppe 6 est constituée par des résines synthétiques, par exemple par du polyuréthane chimique­ment polymérisable à froid en application d'un procédé connu par la publication FR-A-2.446.437.The casing 6 is made up of synthetic resins, for example polyurethane chemically polymerizable under cold conditions by application of a process known from publication FR-A-2,446,437.

Le noyau 7 est constitué par un latté de bois ventilé et cintré recouvert d'un ensemble de garnitures (6a, 6b) dont l'épaisseur est continuellement croissante de la zone de raccordement de la partie avant (3) vers l'arrière du ski.The core 7 is constituted by a block of ventilated and bent wood covered with a set of linings (6a, 6b) whose thickness is continuously increasing from the connection zone of the front part (3) towards the rear of the ski. .

L'ensemble constitué par l'âme 7 et les arma­tures 10 qui lui confèrent la flexibilité souhaitée est ensuite placé dans un moule dans lequel on injecte ou coule par gravité les résines synthétiques.The assembly constituted by the core 7 and the frames 10 which give it the desired flexibility is then placed in a mold into which synthetic resins are injected or poured by gravity.

Selon un autre aspect de l'invention l'enve­loppe 6 est formée par :
- une garniture supérieure 6a qui recouvre la face supérieure et partiellement les faces latérales de l'âme 7 et qui est à base de résines synthétiques.
- une garniture inférieure 6b à rainure médiane 11 (on notera que la rainure 11 s'étend jusqu'à la naissance de la spatule ou partie avant 3) qui recouvre la face inté­rieure et partiellement les faces latérales de l'âme 7 et qui est à base de résines synthétiques spécifiquement chargées. La mise en place de cette garniture peut assurer simultanément la fixation des carres 12.According to another aspect of the invention, the envelope 6 is formed by:
- An upper lining 6a which covers the upper face and partially the lateral faces of the core 7 and which is based on synthetic resins.
- A lower lining 6b with a central groove 11 (it will be noted that the groove 11 extends until the birth of the spatula or front part 3) which covers the inner face and partially the lateral faces of the core 7 and which is based on specifically loaded synthetic resins. The fitting of this lining can simultaneously secure the edges 12.

Sans sortir du cadre de l'invention, le ski proposé pourra être réalisé dans les largeurs courantes selon l'utilisation envisagée.Without departing from the scope of the invention, the proposed ski can be produced in current widths according to the intended use.
