Description

L'invention concerne un mono-ski du type, comportant un talon, une semelle et une spatule, destiné à recevoir un ensemble de fixations de chaussures, dans le but de favoriser la pratique du ski sur tous types de neige.The invention relates to a mono-ski of the type, comprising a heel, a sole and a spatula, intended to receive a set of shoe bindings, with the aim of promoting the practice of skiing on all types of snow.

On sait que la maniabilité d'un tel ski est très aléatoire et dépend essentiellement de l'habileté du skieur qui doit s'efforcer de conserver une position rigoureusement centrée sur l'axe longitudinal du ski. Cette position ne peut être maintenue qu'au prix d'un effort musculaire important dont le relâchement entraîne des chutes et des accidents.We know that the maneuverability of such a ski is very random and depends essentially on the skill of the skier who must strive to maintain a position strictly centered on the longitudinal axis of the ski. This position can only be maintained at the cost of significant muscular effort, the relaxation of which leads to falls and accidents.

L'invention a pour objet un ski perfectionné qui favorise le bon positionnement du skieur dans le but de lui conserver une position naturelle, exempte de contractions musculaires. Par voie de conséquence, les accidents qui en résultaient seront généralement évités.The invention relates to an improved ski which promotes the correct positioning of the skier in order to maintain a natural position, free from muscle contractions. As a result, the resulting accidents will generally be avoided.

Un autre objet de l'invention est un ski acrobatique qui favorise la réalisation de figures de danse ou ballet à l'aide d'un balancier constitué par les bras et les bâtons du skieur.Another object of the invention is a freestyle ski which promotes the production of dance figures or ballet using a balance formed by the arms and poles of the skier.

L'invention a également pour objet un mono-ski assemblé dont les extrémités avant et arrière, plus longues et plus relevées, permettent une attaque différente de la neige, notamment dans les virages.The invention also relates to an assembled mono-ski whose front and rear ends, longer and more raised, allow a different attack from the snow, especially when cornering.

Selon l'invention, le mono-ski est constitué par deux skis élémentaires latéraux portant les fixations de chaussures, accolés à un ski médian et réunis par un moyen d'assemblage manuel qui autorise le déplacement relatif des skis latéraux par rapport au ski médian.According to the invention, the mono-ski consists of two elementary side skis carrying the shoe bindings, attached to a median ski and joined by a manual assembly means which allows the relative movement of the side skis relative to the median ski.

Le ski ainsi réalisé possède par voie de conséquence au moins trois spatules indépendantes qui assouplissent l'extrémité avant du ski dont la spatule centrale plus longue fera office de guide, le talon relevé facilitant l'évolution en neige profonde.The ski thus produced has consequently at least three independent tips which soften the front end of the ski whose longer center tip will act as guide, the raised heel facilitating the evolution in deep snow.

Le mono-ski ainsi réalisé permet notamment une utilisation élargie de skis polyvalents tels que décrits dans la demande de brevet français 85/18228 déposée le 10 décembre 1985 au nom du demandeur.The mono-ski thus produced allows in particular a wider use of versatile skis as described in French patent application 85/18228 filed on December 10, 1985 in the name of the applicant.

Le mono-ski ainsi réalisé facilite l'obtention d'une position naturelle du skieur notamment lors des traversées de la ligne de plus grande pente et dans les virages et plus spécialement en neige molle ou profonde hors piste.The mono-ski thus produced makes it easier to obtain a natural position for the skier, in particular when crossing the steepest line and when cornering, and more particularly in soft or deep snow off piste.

Selon une autre caractéristique de l'invention, le ski médian comporte sur son axe de symétrie longitudinal deux pivots décalés de deux plaques d'assemblage montées à déplacement angulaire limité dont les extrémités sont respectivement au contact de butées portées par l'un et l'autre skis latéraux.According to another characteristic of the invention, the median ski comprises on its longitudinal axis of symmetry two pivots offset by two assembly plates mounted with limited angular displacement, the ends of which are respectively in contact with stops carried by one and the other side skis.

Par voie de conséquence, le ski médian est monté de manière amovible et peut être aisément détaché dans le but de faciliter son transport (sac à dos) lorsque le skieur se déplace sur une neige de qualité variable ou en randonnée. Il sera pliable par charnière centrale.Consequently, the median ski is removably mounted and can be easily detached in order to facilitate its transport (backpack) when the skier is traveling on snow of variable quality or when hiking. It will be foldable by central hinge.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui suit d'un exemple de réalisation du ski, en référence au dessin annexé dans lequel :

  • La figure 1 est une représentation schématique du mono-ski assemblé ;
  • La figure 2 est une représentation schématique d'une variante de réalisation du mono-ski ;
  • La figure 3 est une vue en perspective d'une plaque d'assemblage ;
  • La figure 4 est une vue à une plus grande échelle d'une portion de ski dans sa zone d'assemblage;
  • La figure 5 est une section tranversale du ski assemblé selon la ligne 5.5 de la figure 2 ;
  • La figure 6 est une section transversale du ski asembleé selon une variante de réalisation ;
  • La figure 7 est une section transversale du ski conforme à la figure 6 en réponse à une sollicitation transversale ;
  • La figure 8 est une vue en plan d'une plaque d'assemblage du ski conforme à la réalisation selon la figure 6.
Other characteristics and advantages of the invention will appear on reading the following description of an exemplary embodiment of the ski, with reference to the appended drawing in which:
  • Figure 1 is a schematic representation of the assembled mono-ski;
  • Figure 2 is a schematic representation of an alternative embodiment of the mono-ski;
  • Figure 3 is a perspective view of an assembly plate;
  • Figure 4 is a view on a larger scale of a ski portion in its assembly area;
  • Figure 5 is a cross section of the ski assembled along line 5.5 of Figure 2;
  • Figure 6 is a cross section of the assembled ski according to an alternative embodiment;
  • Figure 7 is a cross section of the ski according to Figure 6 in response to a transverse stress;
  • FIG. 8 is a plan view of a ski assembly plate according to the embodiment according to FIG. 6.

En se référant aux figures 1-2, le mono-ski est constitué par deux skis élémentaires 2-3 accolés à un ski médian 1. Le ski médian 1 de longueur L est plus long que les skis latéraux 2,3 de longueur l et s'étend vers l'avant avec un taux de dépassement de 10% et vers l'arrière avec un taux de 5%.Referring to Figures 1-2, the mono-ski consists of two elementary skis 2-3 attached to a median ski 1. The median ski 1 of length L is longer than the side skis 2.3 of length l and extends forward with a 10% overshoot rate and backwards with a 5% overtake rate.

Ces valeurs approximatives données à titre d'exemple permettent de satisfaire aux conditions d'utilisation du mono-ski.These approximate values given by way of example make it possible to satisfy the conditions of use of the mono-ski.

Dans ces conditions, le talon 4, la semelle 5 et la spatule 6 se présentent suivant un agencement fractionné et facilitent l'évolution de l'arrière et de l'avant du ski.Under these conditions, the heel 4, the sole 5 and the tip 6 are presented in a split arrangement and facilitate the development of the back and front of the ski.

Les skis latéraux portent par ailleurs un ensemble de fixation 7 de chaussures et des moyens d'assemblage et de solidarisation avec le ski médian 1 de largeur identique.The side skis also carry a fastening assembly 7 for shoes and means for assembly and attachment to the median ski 1 of identical width.

Selon une variante de réalisation représentée à la figure 1, le ski médian 1 porte un axe transversal 8 d'articulation et d'assemblage avec les skis latéraux.According to an alternative embodiment shown in Figure 1, the median ski 1 carries a transverse axis 8 of articulation and assembly with the side skis.

Selon une autre variante de réalisation représentée à la figure 2, l'axe 8 est remplacé par un ensemble de plaques d'assemblage 9,9′ respectivement montées à rotation autour de pivots 10,10′, longitudinalement décalés sur l'axe du ski médian. Les plaques sont constituées par des lames à ressort dont chaque extrémité porte un bossage 11 de rétention engageable dans un logement 12 formé dans l'extrémité d'une lame 13 ou fil à ressort accroché sur chacun des flancs extérieurs des skis latéraux 2, 3.According to another alternative embodiment shown in FIG. 2, the axis 8 is replaced by a set of assembly plates 9.9 ′ respectively mounted for rotation about pivots 10.10 ′, longitudinally offset on the axis of the ski median. The plates are constituted by spring blades, each end of which carries a retention boss 11 which can be engaged in a housing 12 formed in the end of a blade 13 or spring wire hung on each of the outer sides of the side skis 2, 3.

Dans le but de faciliter l'évolution du skieur en traversée ou dans les virages, il est prévu de supporter et guider les skis latéraux 2,3 le long des flancs du ski médian 1.In order to facilitate the evolution of the skier when crossing or when cornering, provision is made to support and guide the side skis 2,3 along the sides of the median ski 1.

Ainsi que cela est montré aux figures 4 et 5, le ski médian 1 comporte une semelle 14 élargie avec surplomb latéraux 15 constitutif du support de guidage du flanc d'une moulure latérale 16 des skis 2,3.As shown in FIGS. 4 and 5, the median ski 1 comprises an enlarged sole 14 with lateral overhangs 15 constituting the support for guiding the side of a side molding 16 of the skis 2,3.

Dans ces conditions, le montage du ski autorise un léger déplacement relatif en sens inverse des skis latéraux 2,3 par rapport au ski médian 1 au cours duquel les plaques 9,9′ pivotent légèrement autour des pivots 10,10′ tout en conservant le contact des bossages 11 avec un logement tel que 12.Under these conditions, the mounting of the ski allows a slight relative movement in the opposite direction of the side skis 2.3 relative to the median ski 1 during which the plates 9.9 ′ pivot slightly around the pivots 10.10 ′ while retaining the contact of the bosses 11 with a housing such as 12.

A cet effet, chacune des lames telles que 13 comporte plusieurs logements tels que 12 définissant des crans susceptibles d'autoriser un déplacement relatif des skis 2,3 avec un déplacement limité des lames 13.To this end, each of the blades such as 13 comprises several housings such as 12 defining notches capable of authorizing a relative movement of the skis 2,3 with a limited movement of the blades 13.

Ainsi que cela est montré aux figures 6 à 8, chacun des skis médian 1 et élémentaires latéraux 2,3 est surmonté d'une paire de rotules 21, 21′; 22, 22′; 23, 23′ longitudinalement décalées dont les queues sont respectivement vissées dans les skis correspondants et traversent deux plaques inférieures 19, 19′ à fermoirs latéraux 20 qui assurent l'écartement correct des skis 1, 2, 3.As shown in FIGS. 6 to 8, each of the median 1 and elementary side skis 2, 3 is surmounted by a pair of ball joints 21, 21 ′; 22, 22 ′; 23, 23 ′ longitudinally offset, the tails of which are respectively screwed into the corresponding skis and pass through two lower plates 19, 19 ′ with clasps side 20 which ensure the correct spacing of the skis 1, 2, 3.

Chaque rotule 21, 21′; 22, 22′; 23, 23′ est emboîtée dans un boîtier 24. Les boîtiers tels que 24 sont solidarisés avec deux plaques supérieures d'assemblage 25 dont la partie centrale est montée à rotation autour du pivot constitué par la rotule 22 ou 22′ du ski médian 1.Each ball joint 21, 21 ′; 22, 22 ′; 23, 23 ′ is fitted into a box 24. The boxes such as 24 are secured with two upper assembly plates 25, the central part of which is rotatably mounted around the pivot formed by the ball 22 or 22 ′ of the median ski 1.

Ainsi que cela est montré à la figure 7, l'inclinaison du skieur dans un virage a pour effet de provoquer :
- un déplacement relatif longitudinal des skis latéraux 2, 3 par rapport au ski médian 1 ;
- l'inclinaison transversale simultanée des skis 1, 2, 3. La combinaison des déplacements précités a ainsi pour effet de faciliter l'exécution des virages et la reprise de la position d'aplomb du skieur.As shown in Figure 7, the inclination of the skier in a turn has the effect of causing:
- A relative longitudinal displacement of the side skis 2, 3 relative to the median ski 1;
- The simultaneous transverse inclination of the skis 1, 2, 3. The combination of the abovementioned displacements thus has the effect of facilitating the execution of the turns and the resumption of the upright position of the skier.

Sans sortir du cadre de l'invention, il sera bien entendu possible de faire varier la forme et les dimensions des spatules ainsi que la section du ski.Without departing from the scope of the invention, it will of course be possible to vary the shape and dimensions of the tips as well as the section of the ski.

La semelle du ski pourra, par exemple, comporter une arête longitudinale médiane d'intersection de deux surfaces de glisse planes ou concaves dans le but de permettre le freinage du ski par inclinaison latérale du corps.The sole of the ski may, for example, include a median longitudinal edge of intersection of two flat or concave sliding surfaces in order to allow braking of the ski by lateral inclination of the body.

Pour une meilleure utilisation en toute neige, ce ski sera sensiblement identique aux skis latéraux, permettant l'utilisation de tailles supérieures au moule utilisé pour des mono-skis ayant les plus petites tailles.For better use in all snow, this ski will be substantially identical to the side skis, allowing the use of sizes larger than the mold used for mono-skis having the smallest sizes.
