Description

La présente invention se rapporte à un ski, tel qu'un ski alpin, un ski de fond, un monoski ou un surf pour neige. Elle concerne plus particulièrement un perfectionnement à ce type de ski.The present invention relates to a ski, such as an alpine ski, a cross-country ski, a monoski or a snowboard. It relates more particularly to an improvement in this type of skiing.

On connait déjà différents types de ski et il en existe de très nombreuses variantes. Ceux-ci sont constitués par une poutre de forme allongée dont l'extrémité avant est courbée vers le haut pour constituer une spatule, l'extrémité arrière l'étant aussi plus légèrement pour constituer le talon.We already know different types of ski and there are many variations. These consist of an elongated beam, the front end of which is curved upwards to form a spatula, the rear end also being more slightly to form the heel.

Les skis actuels ont généralement une structure composite dans laquelle sont combinés différents matériaux de manière que chacun d'eux intervienne de façon optimale, compte-tenu de la distribution des contraintes mécaniques lors de l'utilisation du ski. Ainsi, la structure comprend généralement des éléments de protection périphériques, des éléments internes de résistance pour résister aux contraintes de flexion et de torsion, et un noyau. Ces éléments sont assemblés par collage ou par injection, l'assemblage s'effectuant généralement à chaud dans un moule présentant la forme définitive du ski, avec une partie avant fortement relevée en spatule, une partie arrière légèrement relevée en talon, une partie centrale cambrée.Current skis generally have a composite structure in which different materials are combined so that each of them intervenes optimally, taking into account the distribution of mechanical stresses when using the ski. Thus, the structure generally comprises peripheral protective elements, internal resistance elements to resist the flexural and torsional stresses, and a core. These elements are assembled by gluing or by injection, the assembly generally being carried out hot in a mold having the final shape of the ski, with a front part strongly raised in a tip, a rear part slightly raised in the heel, a central arched part. .

Malgré le souci des constructeurs de fabriquer des skis de bonne qualité, ceux-ci n'ont pas, à ce jour trouvé un ski de haute performance satisfaisant dans toutes les conditions d'utilisation.Despite the manufacturers' concern to manufacture good quality skis, they have not, to date found a high performance ski satisfactory in all conditions of use.

La présente invention concerne des perfectionnements apportés à ces skis dans le but de faciliter, leur fabrication qui permet d'obtenir les caractéristiques désirées. de par la diversité des paramètres pouvant être choisis.The present invention relates to improvements made to these skis in order to facilitate their manufacture which makes it possible to obtain the desired characteristics. due to the diversity of parameters that can be chosen.

Le ski selon l'invention est constitué par un premier ensemble inférieur ou embase, et un deuxième ensemble supérieur ou raidisseur, les deux ensembles étant liés l'un avec l'autre par des moyens de liaison réalisés par une liaison souple et/ou partiellement rigide.The ski according to the invention consists of a first lower assembly or base, and a second upper assembly or stiffener, the two assemblies being linked with each other by connection means produced by a flexible connection and / or partially rigid.

Selon une caractéristique complémentaire, le raidisseur a une longueur inférieure à la longueur de la surface de l'embase en contact avec la neige. Elle est avantageusement comprise entre 50 et 100 % de la longueur de l'embase mesurée entre les deux lignes de contact avec la neige.According to an additional characteristic, the stiffener has a length less than the length of the surface of the base in contact with the snow. It is advantageously between 50 and 100% of the length of the base measured between the two lines of contact with the snow.

Selon une disposition avantageuse l'embase et le raidisseur sont des poutres de forme allongée dont la hauteur peut être variable le long du ski pour diminuer vers les extrémités avant et arrière.According to an advantageous arrangement the base and the stiffener are elongated beams whose height can be variable along the ski to decrease towards the front and rear ends.

Selon l'un des mode de réalisation, la liaison entre l'embase et le raidisseur est réalisée par une interface souple, constituée par une feuille en matériau élastique ou viscoélastique, et s'étend sous toute la surface inférieure du raidisseur.According to one of the embodiments, the connection between the base and the stiffener is produced by a flexible interface, constituted by a sheet of elastic or viscoelastic material, and extends under the entire lower surface of the stiffener.

Selon une autre variante, la liaison souple est partielle et ne s'étend que sous une partie de la longueur du raidisseur.According to another variant, the flexible connection is partial and extends only under part of the length of the stiffener.

Selon une autre variante, la liaison entre l'embase et le raidisseur est une liaison rigide et ne s'étend pas sous toute la surface inférieure du raidisseur.According to another variant, the connection between the base and the stiffener is a rigid connection and does not extend under the entire lower surface of the stiffener.

La figure 1 représente un ski selon un premier mode de réalisation selon l'invention. Il comprend un ensemble inférieur ou embase (1) et un ensemble supérieur ou raidisseur (2) Ledit raidisseur (2) est disposé au-dessus de l'embase (1) et lié à cette dernière par des moyens de liaison (3).FIG. 1 represents a ski according to a first embodiment according to the invention. It comprises a lower assembly or base (1) and an upper assembly or stiffener (2) Said stiffener (2) is disposed above the base (1) and linked to the latter by connecting means (3).

L'embase (1) est l'élément en contact avec la neige et se présente sous la forme d'une poutre (10) allongée ayant sa propre distribution d'épaisseur, de largeur et donc sa propre raideur. Cette poutre allongée pouvant avoir une raideur plus faible ou égale à celle d'un ski classique. L'embase (1) comprend une partie centrale (113) légèrement cambrée, présentant une surface inférieure (114) de glissement et une surface supérieure (115). La partie centrale (113) occupe la plus grande partie de la longueur de l'embase et se prolonge d'une part à l'avant par une partie antérieure (116) relevée pour former la spatule (117) et d'autre part, par une partie postérieure (118) légèrement relevée pour former le talon du ski. La partie postérieure (118) étant relativement de faible longueur et de relèvement faible, et la partie antérieure (116) est plus longue et beaucoup plus cambrée, comme il est connu en soi et représenté sur les figures.The base (1) is the element in contact with the snow and is in the form of an elongated beam (10) having its own distribution of thickness, of width and therefore its own stiffness. This elongated beam can have a stiffness less than or equal to that of a conventional ski. The base (1) comprises a central part (113) slightly arched, having a lower sliding surface (114) and an upper surface (115). The central part (113) occupies most of the length of the base and is extended on the one hand at the front by an anterior part (116) raised to form the spatula (117) and on the other hand, by a rear part (118) slightly raised to form the heel of the ski. The rear part (118) being relatively short and of low lift, and the front part (116) is longer and much more arched, as is known per se and shown in the figures.

La structure de l'embase (1) peut être du type sandwich ou du type à caisson ou de tout autre type. A la figure 2, on a représenté une structure préférée comprenant un renfort supérieur (101) rigide en forme de coque à section en "U" formant une paroi supérieure (102) et deux parois latérales (103 et 104), recouvrant un noyau (105), l'ensemble étant fermé à sa partie inférieure par un élément inférieur (106) comportant les carres métalliques (107,108), une couche (109) de glissement généralement en polyéthylène ainsi que des éléments de renfort inférieur (110,111). Une couche supérieure superficielle (112) recouvre le renfort supérieur pour former le décor de l'embase.The structure of the base (1) can be of the sandwich type or of the box type or of any other type. In FIG. 2, a preferred structure is shown comprising a rigid upper reinforcement (101) in the form of a shell with a "U" section forming a top wall (102) and two side walls (103 and 104), covering a core ( 105), the assembly being closed at its lower part by a lower element (106) comprising the metal edges (107, 108), a sliding layer (109) generally made of polyethylene as well as lower reinforcement elements (110, 111). An upper surface layer (112) covers the upper reinforcement to form the decor of the base.

Les couches de renfort (101,110,111) peuvent être de tous types tels que des couches de matériaux composites comme de la fibre de verre, fibre de carbone avec de la résine époxy ou polyester, ou en alliage métallique.The reinforcing layers (101,110,111) can be of all types such as layers of composite materials such as fiberglass, carbon fiber with epoxy or polyester resin, or a metal alloy.

Le noyau (105) peut être de la mousse chargée ou non, du bois ou du nid d'abeille en aluminium.The core (105) can be filled or unloaded foam, wood or aluminum honeycomb.

La couche superficielle assurant le décor peut être en polyamide ou autre, tel qu'en matériau thermoplastique. Elle peut être monocouche ou constituée de plusieurs couches.The surface layer providing the decoration can be made of polyamide or other material, such as a thermoplastic material. It can be monolayer or made up of several layers.

Selon l'invention, la face supérieure (115) de la partie centrale (113) de l'embase (1) est recouverte d'un raidisseur (2). Cet élément est destiné à compléter la distribution des raideurs de l'embase (1) de manière à obtenir la distribution globale souhaitée. Ledit raidisseur (2) peut être de toute nature, de toute forme et de toute structure.According to the invention, the upper face (115) of the central part (113) of the base (1) is covered with a stiffener (2). This element is intended to complete the distribution of the stiffnesses of the base (1) so as to obtain the desired overall distribution. Said stiffener (2) can be of any kind, any shape and any structure.

Selon une disposition avantageuse, le raidisseur (2) se présente sous la forme d'une partie (20) allongée ayant aussi sa propre distribution d'épaisseur, de largeur et donc de raideur.According to an advantageous arrangement, the stiffener (2) is in the form of an elongated part (20) also having its own distribution of thickness, width and therefore stiffness.

Dans le mode de réalisation donné à titre d'exemple et représenté à la figure 3, la structure du raidisseur est du type caisson et est formé d'un noyau (201) disposé entre un renfort supérieur (202) et un renfort inférieur (203). Bien entendu la structure pourrait également être du type sandwich, c'est à dire être constituée d'un empilement de différents éléments tels que renforts et noyaux. Le raidisseur (2) peut être aussi constitué par un simple profilé en forme de "Omega" par exemple, tel qu'il est représenté à la figure 4. Dans ce cas, on peut prévoir de réaliser le raidisseur en matériau composite par la technique des TRE (Thermoplastique Renforcé Estampable) ou SMC (Sheet Molding Compound) par exemple.In the embodiment given by way of example and represented in FIG. 3, the structure of the stiffener is of the box type and is formed of a core (201) disposed between an upper reinforcement (202) and a lower reinforcement (203 ). Of course, the structure could also be of the sandwich type, that is to say be made up of a stack of different elements such as reinforcements and cores. The stiffener (2) can also be constituted by a simple section in the shape of an "Omega" for example, as shown in FIG. 4. In this case, provision can be made to make the stiffener in composite material by the technique TRE (Reinforced Stampable Thermoplastic) or SMC (Sheet Molding Compound) for example.

Le renfort supérieur (202) est recouvert d'une autre couche de renfort supplémentaire (204) en forme de "U" renversé et formant une paroi supérieure (205) et deux parois latérales (206,207). Une couche superficielle (208) recouvre le dessus et les faces latérales du raidisseur (2) pour former la finition et le décor de celui-ci.The upper reinforcement (202) is covered with another additional reinforcement layer (204) in the shape of an inverted "U" and forming an upper wall (205) and two side walls (206,207). A surface layer (208) covers the top and the side faces of the stiffener (2) to form the finish and the decoration thereof.

Comme précédemment pour l'embase, les couches de renfort du raidisseur peuvent être de tous types tels que des couches de matériaux composites comme de la fibre de verre, fibre de carbone, avec de la résine époxy ou polyester ou encore des renforts métalliques. Le noyau (201) peut être de la mousse chargée ou non, du bois ou du nid d'abeille en aluminium. La couche superficielle assurant le décor peut être en polyamide.As previously for the base, the reinforcing layers of the stiffener can be of all types such as layers of composite materials such as fiberglass, carbon fiber, with epoxy or polyester resin or even metallic reinforcements. The core (201) can be filled or unloaded foam, wood or aluminum honeycomb. The surface layer providing the decoration can be made of polyamide.

Selon une disposition avantageuse, (figure 5), le raidisseur (2) a une longueur "L2" inférieure à la longueur "L1" de l'embase (1). Ainsi, l'extrémité avant (209) du raidisseur se situe entre le point (119) de contact spatule de l'embase et l'extrémité avant (120) de la zone normalisée de montage des fixations. De même, l'extrémité arrière (210) du raidisseur se situe entre le point de contact arrière (121) et l'extrémité arrière (122) de la zone normalisée de montage des fixations. Ainsi, si l'embase (1) a une longueur "L1" de contact avec la neige, le raidisseur (2) a une longueur "L2" telle que "L2" soit inférieure à "L1".According to an advantageous arrangement, (FIG. 5), the stiffener (2) has a length "L2" less than the length "L1" of the base (1). Thus, the front end (209) of the stiffener is located between the tip contact point (119) of the base and the front end (120) of the standardized area for mounting the fasteners. Similarly, the rear end (210) of the stiffener is located between the rear contact point (121) and the rear end (122) of the standardized area for mounting the fasteners. Thus, if the base (1) has a length "L1" of contact with the snow, the stiffener (2) has a length "L2" such that "L2" is less than "L1".

A titre d'exemple, la longueur "L2" du raidisseur est comprise entre 50 % et 100 % de la longueur "L1". De plus, la position longitudinale relative du raidisseur (2) par rapport à l'embase (1) peut être par exemple telle que le milieu (211) du raidisseur (2) soit au niveau du milieu (123) de la longueur (L1) de contact de l'embase (1) avec la neige. Mais il pourrait en être autrement ; ainsi le milieu (211) du raidisseur (2) peut être plus en avant (AV) ou plus en arrière (AR) par rapport au milieu (123) de l'embase.For example, the length "L2" of the stiffener is between 50% and 100% of the length "L1". In addition, the relative longitudinal position of the stiffener (2) relative to the base (1) may for example be such that the middle (211) of the stiffener (2) is at the middle (123) of the length (L1 ) contact of the base (1) with snow. But it could be otherwise; thus the middle (211) of the stiffener (2) can be further forward (AV) or further back (AR) relative to the middle (123) of the base.

En ce qui concerne la largeur des deux éléments, le raidisseur (2) peut avoir la même largeur que la largeur de l'embase (1), comme cela est représenté plus particulièrement à la figure 3. Mais il peut en être autrement ; ainsi le raidisseur (2) peut avoir une largeur "l2" inférieure à la largeur "l1" de l'embase (1) et être ainsi plus étroit que cette dernière, comme cela est représenté schématiquement à la figure 5. De même, le raidisseur (2 ) peut être plus large que l'embase (1), comme cela est représenté à la figure 7.As regards the width of the two elements, the stiffener (2) can have the same width as the width of the base (1), as shown more particularly in FIG. 3. But it can be otherwise; thus the stiffener (2) may have a width "l2" less than the width "l1" of the base (1) and thus be narrower than the latter, as shown diagrammatically in FIG. 5. Similarly, the stiffener (2) can be wider than the base (1), as shown in Figure 7.

Notons aussi que la largeur des deux ensembles embase (1) et/ou raidisseur (2) peut être constante ou variable comme cela est représenté aux figures 8, 9 et 10.Note also that the width of the two base unit (1) and / or stiffener (2) can be constant or variable as shown in Figures 8, 9 and 10.

La figure 8 montre, en vue de dessus, un exemple de réalisation d'un ski selon lequel la largeur "l2" du raidisseur (2) est variable et suit à peu près la variation de la largeur "l1" de l'embase (1).FIG. 8 shows, in top view, an exemplary embodiment of a ski according to which the width "l2" of the stiffener (2) is variable and roughly follows the variation of the width "l1" of the base ( 1).

La figure 9 est une vue similaire à la figure 7 représentant un autre mode de réalisation selon lequel la largeur "l1" de l'embase (1) est variable tandis que la largeur "l2" du raidisseur est constante.Figure 9 is a view similar to Figure 7 showing another embodiment in which the width "l1" of the base (1) is variable while the width "l2" of the stiffener is constant.

La figure 10 est une autre variante selon laquelle la variation de la largeur "l2" du raidisseur est inverse de celle de la largeur "l1" de l'embase, c'est-à-dire que lorsque la largeur "l1" de l'embase 1 augmente, la largeur "l2" du raidisseur 2 diminue.FIG. 10 is another variant according to which the variation of the width "l2" of the stiffener is opposite to that of the width "l1" of the base, that is to say that when the width "l1" of l 'base 1 increases, the width "l2" of the stiffener 2 decreases.

Selon les modes de réalisation des figures 8 à 10, la variation de la largeur "l2" du raidisseur est continue, mais il pourrait en être autrement, comme cela est représenté à la figure 11. Selon cette variante, le raidisseur 2 comprend dans sa zone centrale (212) un rétrécissement de largeur pour former deux dégagements latéraux (213,214) s'étendant sur une longueur "L'2" inférieure à "L2" , le raidisseur (2) comprenant ainsi une partie centrale (215) de largeur réduite.According to the embodiments of FIGS. 8 to 10, the variation of the width "l2" of the stiffener is continuous, but it could be otherwise, as shown in FIG. 11. According to this variant, the stiffener 2 comprises in its central zone (212) a narrowing in width to form two lateral clearances (213,214) extending over a length "L'2" less than "L2", the stiffener (2) thus comprising a central part (215) of reduced width .

De la même façon et comme représenté à la figure 12 le raidisseur (2) peut comprendre avantageusement un rétrécissement de son épaisseur dans la zone centrale (212) s'étendant sur une longueur L''2 inférieure à L2. Le dégagement ainsi formé dans la région prévue pour le montage des fixations permet de réduire la hauteur entre la chaussure du skieur et la neige.In the same way and as shown in FIG. 12, the stiffener (2) can advantageously comprise a narrowing of its thickness in the central zone (212) extending over a length L''2 less than L2. The clearance thus formed in the region provided for the mounting of the bindings makes it possible to reduce the height between the skier's shoe and the snow.

L'embase (1) et le raidisseur (2) sont des parties allongées de hauteur respective "h1" et "h2". Bien entendu dans une coupe transversale les deux hauteurs "h1" et "h2" peuvent avoir la même valeur, mais aussi, être différentes. Ainsi, dans une coupe transversale, "h1" peut être supérieur ou inférieur à "h2". De plus, "h1" et/ou "h2" peut être constant en fonction de la position longitudinale où est faite la mesure. Toutefois, pour obtenir une bonne répartition de la raideur, il est avantageux de faire varier l'une ou l'autre des hauteurs "h1" ou "h2" et même les deux "h1" et "h2". Ainsi le raidisseur peut avoir sa hauteur "h2" qui diminue vers l'avant ou vers l'arrière, voire même à la fois vers l'avant et vers l'arrière comme cela est représenté. Il en est de même pour l'embase.The base (1) and the stiffener (2) are elongated parts of respective height "h1" and "h2". Of course in a cross section the two heights "h1" and "h2" can have the same value, but also be different. Thus, in a cross section, "h1" can be greater or less than "h2". In addition, "h1" and / or "h2" can be constant depending on the longitudinal position where the measurement is made. However, to obtain a good distribution of the stiffness, it is advantageous to vary one or the other of the heights "h1" or "h2" and even the two "h1" and "h2". Thus the stiffener can have its height "h2" which decreases towards the front or towards the rear, or even both both towards the front and towards the rear as shown. It is the same for the base.

Selon l'invention, le raidisseur (2) est lié à l'embase (1) par des moyens de liaison (3) tels que la liaison entre les deux éléments soit souple et/ou partiellement rigide.According to the invention, the stiffener (2) is linked to the base (1) by connection means (3) such that the connection between the two elements is flexible and / or partially rigid.

Le mode de réalisation représenté aux figures 1, 2 et 3 représente un exemple selon lequel la liaison (3) entre les deux ensembles embase (1) et raidisseur (2) est totalement souple. A cet effet, les moyens de liaison (3) sont réalisés par une interface (30) souple et disposée entre les deux ensembles, sous toute la longueur du raidisseur. L'interface a donc une largeur "l2" égale à celle du raidisseur (2) et une longueur "L2" égale à celle de ce dernier.The embodiment shown in Figures 1, 2 and 3 shows an example where the connection (3) between the two base assemblies (1) and stiffener (2) is completely flexible. To this end, the connecting means (3) are produced by a flexible interface (30) arranged between the two assemblies, over the entire length of the stiffener. The interface therefore has a width "l2" equal to that of the stiffener (2) and a length "L2" equal to that of the latter.

L'interface (30) est réalisée par une couche d'un matériau souple du type élastique, et notamment du type viscoélastique, d' épaisseur de 0,1 à 5 mm, qui est collé ou soudé d'une part sur la surface supérieure (115) de l'embase (1) et d'autre part sous la surface inférieure (216) du raidisseur. Le matériau utilisé peut être élastique d'une dureté de 10 à 85 shores A ou du matériau viscoélastique de module d'élasticité de 15 à 160 mégapascal d'une dureté de 50 à 95 shores A et d'une valeur d'amortissement de 0,13 à 0,72. Bien entendu, ces données ne sont que des exemples de réalisation, et pour une température de 20 degrés et une fréquence de 15 hertz .The interface (30) is produced by a layer of a flexible material of the elastic type, and in particular of the viscoelastic type, of thickness from 0.1 to 5 mm, which is glued or welded on the one hand to the upper surface. (115) of the base (1) and on the other hand under the lower surface (216) of the stiffener. The material used can be elastic with a hardness of 10 to 85 shores A or viscoelastic material with a modulus of elasticity of 15 to 160 megapascal, a hardness of 50 to 95 shores A and a damping value of 0 , 13-0.72. Of course, these data are only examples of implementation, and for a temperature of 20 degrees and a frequency of 15 hertz.

La fixation de l'interface (30) sur l'embase (1) et le raidisseur (2) est réalisée soit par une résine thermodurcissable du type époxyde polyester, vinylester ou polyuréthane ou un film thermoplastique tel qu'un polyamide, ou tout autre moyen.The interface (30) is fixed to the base (1) and the stiffener (2) is produced either by a thermosetting resin of the polyester, vinylester or polyurethane epoxy type or a thermoplastic film such as a polyamide, or any other way.

La liaison souple selon la variante de réalisation précédemment décrite est totale et s'étend sous la totalité de la longueur (L2) du raidisseur (2), mais il peut en être autrement. En effet, la liaison souple ne peut être que partielle et ne pas s'étendre sous la totalité de la longueur du raidisseur (2), comme cela est représenté aux figures 13 et 14.The flexible connection according to the embodiment previously described is total and extends under the entire length (L2) of the stiffener (2), but it can be otherwise. Indeed, the flexible connection can only be partial and not extend under the entire length of the stiffener (2), as shown in FIGS. 13 and 14.

La figure 13 représente donc une première variante selon laquelle la liaison (3) est souple et partielle, et est réalisée par deux interfaces souples, une première interface avant souple (31) et une deuxième interface arrière souple (32) disposées respectivement sous l'extrémité avant (209) et l'extrémité arrière (210) du raidisseur (2).FIG. 13 therefore represents a first variant according to which the connection (3) is flexible and partial, and is produced by two flexible interfaces, a first flexible front interface (31) and a second flexible rear interface (32) disposed respectively under the front end (209) and rear end (210) of the stiffener (2).

La figure 14 représente une deuxième variante selon laquelle la liaison souple (3) est réalisée par une interface centrale souple (33) disposée entre l'embase (1) et le raidisseur (2) dans la zone centrale du ski et dont la longueur "L3" est inférieure à la longueur "L2" dudit raidisseur, pour constituer une liaison souple partielle.FIG. 14 represents a second variant according to which the flexible connection (3) is produced by a flexible central interface (33) disposed between the base (1) and the stiffener (2) in the central zone of the ski and the length of which " L3 "is less than the length" L2 "of said stiffener, to constitute a partial flexible connection.

Selon d'autres variantes, la liaison (3) entre l'embase (1) et le raidisseur (2) est partiellement rigide ; c'est-à-dire que la liaison, quand elle est rigide, ne s'étend pas sous toute la surface du raidisseur (2) comme cela est représenté aux figures 15 et 16.According to other variants, the connection (3) between the base (1) and the stiffener (2) is partially rigid; that is to say that the connection, when it is rigid, does not extend under the entire surface of the stiffener (2) as shown in FIGS. 15 and 16.

La figure 15 montre une variante selon laquelle la liaison (3) est partielle et rigide ; c'est-à-dire que le raidisseur (2) est lié de façon rigide et par sa surface inférieure centrale (218) à l'embase (1). Ainsi, seule la partie centrale (212) est fixée à l'embase (1) tandis que la partie avant (219) et la partie arrière (220) sont libres.FIG. 15 shows a variant according to which the connection (3) is partial and rigid; that is to say that the stiffener (2) is rigidly connected by its central lower surface (218) to the base (1). Thus, only the central part (212) is fixed to the base (1) while the front part (219) and the rear part (220) are free.

La figure 16 montre une autre disposition où la liaison (3) est rigide et partielle. Selon cette disposition, seules les extrémités avant et arrière (209 et 210) du raidisseur (2) sont fixées à l'embase (1) pour laisser libre la zone centrale (212).Figure 16 shows another arrangement where the connection (3) is rigid and partial. According to this arrangement, only the front and rear ends (209 and 210) of the stiffener (2) are fixed to the base (1) to leave the central area (212) free.

La liaison rigide (3) peut être obtenue par tout moyen tel que collage, par liaison mécanique comme des vis ou des rivets ou même par soudage, notamment par ultrasons ou par vibrations.The rigid connection (3) can be obtained by any means such as bonding, by mechanical connection such as screws or rivets or even by welding, in particular by ultrasound or by vibration.

Bien entendu la liaison (3) entre l'embase (1) et son raidisseur (2) peut être mixte, c'est-à-dire en partie souple et en partie rigide comme cela est représenté à la figure 17.Of course, the connection (3) between the base (1) and its stiffener (2) can be mixed, that is to say partly flexible and partly rigid as shown in FIG. 17.

Ainsi selon la variante de la figure 17, la zone centrale du ski comprend une liaison centrale (33) souple, tandis que les extrémités avani et arrière (209 et 210) du raidisseur sont fixées à l'embase (1) par deux liaisons partielles, rigides, une première liaison rigide ou liaison avant (35) et une deuxième liaison rigide ou liaison arrière (36).Thus, according to the variant of FIG. 17, the central zone of the ski comprises a flexible central link (33), while the front and rear ends (209 and 210) of the stiffener are fixed to the base (1) by two partial links , rigid, a first rigid link or front link (35) and a second rigid link or rear link (36).

Selon la variante de la figure 18, la disposition est inverse. Ainsi, la liaison partielle rigide (34) est au centre comme selon la variante de la figure 15, mais les parties avant (219) et arrière (220) du raidisseur (2) sont liées à l'embase par des liaisons partielles souples, une première liaison avant souple (31) et une deuxième liaison arrière souple (32). La liaison centrale rigide (34) pouvant être obtenue par une saillie vers le bas venant du raidisseur ou une cale intermédiaire centrale ou interface rigide centrale (340).According to the variant of Figure 18, the arrangement is opposite. Thus, the rigid partial connection (34) is in the center as in the variant of FIG. 15, but the front (219) and rear (220) parts of the stiffener (2) are linked to the base by flexible partial connections, a first flexible front link (31) and a second flexible rear link (32). The rigid central link (34) can be obtained by a downward projection coming from the stiffener or a central intermediate wedge or central rigid interface (340).

Les figures 19 et 20 représentent le cas où le raidisseur est lié à l'embase par ses extrémités avant et arrière (209, 210) et où les fixations (5) sont directement liées au raidisseur. Afin d'éviter un éventuel arrachement du raidisseur et permettre de régler l'amplitude du déplacement du raidisseur par rapport à l'embase, une vis de réglage (22) s'appuyant sur une bague élastomère (23) relie élastiquement le raidisseur (2) à l'embase (1) dans la partie centrale du ski.Figures 19 and 20 show the case where the stiffener is linked to the base by its front and rear ends (209, 210) and where the fasteners (5) are directly linked to the stiffener. In order to avoid possible tearing of the stiffener and to adjust the amplitude of movement of the stiffener relative to the base, an adjustment screw (22) resting on an elastomer ring (23) elastically connects the stiffener (2 ) at the base (1) in the central part of the ski.

Les déplacements longitudinaux du raidisseur sont rendus possibles en prévoyant un espace de quelques dixièmes de mm. dans le sens longitudinal entre l'épaulement (220) de la vis (22) traversant le raidisseur et les parois internes du trou du raidisseur.The longitudinal displacements of the stiffener are made possible by providing a space of a few tenths of mm. in the longitudinal direction between the shoulder (220) of the screw (22) passing through the stiffener and the internal walls of the hole in the stiffener.

Les figures 21 et 22 représentent une variante des figures 18 et 19 dans lesquelles le raidisseur est relié à l'embase par une tige transversale (24) solidaire du raidisseur (2) et chaque extrémité de la tige prend appui latéralement dans un trou oblong (15) réalisé dans l'embase, et particulièrement à travers un rebord latéral (16) de l'embase. La tige transversale (24) est fixé transversalement à l'embase par tout moyen de retenue approprié. Les déplacements longitudinaux du raidisseur par rapport à l'embase sont rendus possibles comme dans le mode de réalisation précédent.Figures 21 and 22 show a variant of Figures 18 and 19 in which the stiffener is connected to the base by a transverse rod (24) integral with the stiffener (2) and each end of the rod bears laterally in an oblong hole ( 15) produced in the base, and particularly through a lateral flange (16) of the base. The transverse rod (24) is fixed transversely to the base by any suitable retaining means. The longitudinal displacements of the stiffener relative to the base are made possible as in the previous embodiment.

Selon les modes de réalisation précédemment décrits, la surface supérieure (115) de l'embase est une surface dont la génératrice est parallèle à la surface inférieure (114) de glissement. Mais on pourrait concevoir que la surface supérieure (115) soit en bas et inclinée comme cela est représenté à la figure 23 où l'interface de liaison (3) est inclinée soit vers l'intérieur du ski, soit vers l'extérieur.According to the embodiments previously described, the upper surface (115) of the base is a surface whose generator is parallel to the lower sliding surface (114). However, it could be conceived that the upper surface (115) is at the bottom and inclined as shown in FIG. 23 where the connection interface (3) is inclined either towards the inside of the ski, or towards the outside.

Les figures 24, 25 et 26 sont des vues schématiques dans une coupe transversale de trois autres variantes de forme de l'interface.Figures 24, 25 and 26 are schematic views in cross section of three other alternative forms of the interface.

Selon ces différentes variantes, la zone de l'interface n'est pas plane mais a une forme complexe. Selon la variante de la figure 24, la surface de l'interface (3) est courbe. Selon la variante de la figure 25, l'embase (1) comprend un profil en creux longitudinal et la surface inférieure (216) du raidisseur (2) comprend un profil en salle correspondant. La disposition représentée à la figure 26 est inverse. Ainsi l'embase (1) comprend sur le dessus un profil en saillie et la surface inférieure (216) du raidisseur comprend un profil en creux correspondant.According to these different variants, the interface area is not flat but has a complex shape. According to the variant of FIG. 24, the surface of the interface (3) is curved. According to the variant of FIG. 25, the base (1) comprises a longitudinal hollow profile and the lower surface (216) of the stiffener (2) comprises a corresponding room profile. The arrangement shown in Figure 26 is reversed. Thus the base (1) comprises on the top a projecting profile and the lower surface (216) of the stiffener comprises a corresponding hollow profile.

Selon le mode de réalisation précédent, la surface inférieure (216) du raidisseur (2) a une forme complémentaire à la surface supérieure (115) de l'embase, et ce du moins au niveau de la liaison, mais il pourrait en être autrement, comme cela est représenté à la variante de la figure 27 selon laquelle c'est la liaison (3) qui assure la coopération de forme, d'une part avec l'embase (1) à sa surface inférieure, et d'autre part avec le raidisseur (2) à sa surface supérieure.According to the previous embodiment, the lower surface (216) of the stiffener (2) has a shape complementary to the upper surface (115) of the base, and this at least at the connection, but it could be otherwise. , as shown in the variant of FIG. 27 according to which it is the connection (3) which ensures the form cooperation, on the one hand with the base (1) at its lower surface, and on the other hand with the stiffener (2) on its upper surface.

Notons que la couche superficielle (112) de l'embase (1) peut s'étendre sur toute la longueur de celle-ci, y compris dans la zone de la liaison ou seulement dans les zones où il n'y a pas ladite liaison (3).Note that the surface layer (112) of the base (1) can extend over the entire length thereof, including in the area of the connection or only in areas where there is no said connection (3).

Selon les figures 1, 2 et 3, on voit que la couche superficielle (112) est interrompue au niveau de la liaison. Ainsi la liaison souple et donc l'interface (30) est directement fixée sur le renfort supérieur (101) de l'embase.According to Figures 1, 2 and 3, it can be seen that the surface layer (112) is interrupted at the level of the connection. Thus the flexible connection and therefore the interface (30) is directly fixed to the upper reinforcement (101) of the base.

La figure 3a montre une variante selon laquelle la couche superficielle (112) de l'embase s'étend même dans la zone de la liaison. Ainsi l'interface (30) est fixée sur la couche superficielle (112) de ladite embase (1).FIG. 3a shows a variant according to which the surface layer (112) of the base extends even in the region of the connection. Thus the interface (30) is fixed on the surface layer (112) of said base (1).

La rigidité du raidisseur (2) peut être inférieure ou égale à celle de l'embase (1).The stiffness of the stiffener (2) may be less than or equal to that of the base (1).

Les figures 28 et 29 représentent des variantes selon lesquelles le raidisseur (2) monté sur une interface souple, est retenu longitudinalement par rapport à l'embase (1). A cet effet l'embase (1) comprend deux butées, une première butée avant (130), et une deuxième butée arrière (131). La figure 28 est un mode de réalisation selon laquelle le raidisseur est en quelque sorte encastré dans l'embase. La figure 29 est un autre mode de réalisation.Figures 28 and 29 show variants in which the stiffener (2) mounted on a flexible interface is retained longitudinally relative to the base (1). For this purpose the base (1) comprises two stops, a first front stop (130), and a second rear stop (131). Figure 28 is an embodiment according to which the stiffener is somehow embedded in the base. Figure 29 is another embodiment.

Les réalisations des figures 14 et 15 permettent d'obtenir un ski dont la rigidité varie de façon non linéaire avec la déformée du ski. Ce ski réagissant différemment en fonction de la vitesse et de l'amplitude des flexions. En effet au repos et lors de faibles flexions, étant donné la présence des espaces avant (ea) et arrière (er), l'embase n'est pas en contact avec les extrémités du raidisseur. Par contre, à partir d'une certaine flexion, il y a contact et action du raidisseur sur l'embase. La figure 30 représente de façon schématique, la courbe de la raideur du ski en fonction de la flexion de celui-ci.The embodiments of FIGS. 14 and 15 make it possible to obtain a ski whose stiffness varies non-linearly with the deformation of the ski. This ski reacting differently depending on the speed and amplitude of the flexions. Indeed, at rest and during slight bending, given the presence of the front (ea) and rear (er) spaces, the base is not in contact with the ends of the stiffener. On the other hand, from a certain bending, there is contact and action of the stiffener on the base. FIG. 30 schematically represents the curve of the stiffness of the ski as a function of the bending of the latter.

On peut aussi noter que la liaison souple réalisée avec une interface élastique et réalisée avec une feuille peut être telle que ladite feuille ait une épaisseur constante ou variable. Par exemple, étant de plus en plus épaisse vers l'avant ou inversement, voire même plus épaisse à la fois vers l'avant et vers l'arrière. On pourrait aussi concevoir l'utilisation d'une couche de matériau souple dont les propriétés soient telles que la raideur ne soit pas constante tout au long de cette couche. En effet elle pourrait être plus souple à l'avant ou inversement.It can also be noted that the flexible connection produced with an elastic interface and produced with a sheet may be such that said sheet has a constant or variable thickness. For example, being thicker towards the front or vice versa, or even thicker both forwards and backwards. One could also conceive of the use of a layer of flexible material whose properties are such that the stiffness is not constant throughout this layer. Indeed it could be more flexible at the front or vice versa.

La figure 31 montre un perfectionnement particulièrement adapté quand le raidisseur (2) présente une largeur inférieure à l'embase (1).Figure 31 shows an improvement particularly suitable when the stiffener (2) has a width less than the base (1).

Ainsi selon ce perfectionnement, le ski comprend au moins un support (4) destiné à recevoir la ou les fixations (5) de retenue de la chaussure du skieur. Cedit support (4) a la forme d'un étrier ayant la forme d'un "U" renversé et comprend une paroi supérieure (40) prolongée latéralement et vers le bas par deux parois latérales (41, 42) pour constituer un logement (43) inférieur ayant la forme d'un profil en creux s'étendant longitudinalement destiné au passage du raidisseur (2). Il faut noter que les dimensions du logement aussi bien horizontale "l4" que verticale "h4" sont supérieures aux dimensions horizontale "l2" et verticale "h2" du raidisseur pour former un espace "e" nécessaire à la liberté de ce dernier.Thus according to this improvement, the ski comprises at least one support (4) intended to receive the binding (s) (5) for retaining the skier's boot. Said support (4) has the shape of a stirrup having the shape of an inverted "U" and comprises an upper wall (40) extended laterally and downwards by two side walls (41, 42) to constitute a housing ( 43) lower having the shape of a longitudinally extending hollow profile intended for the passage of the stiffener (2). It should be noted that the dimensions of the housing both horizontal "l4" and vertical "h4" are greater than the horizontal dimensions "l2" and vertical "h2" of the stiffener to form a space "e" necessary for the freedom of the latter.

Selon une caractéristique de l'invention, le raidisseur ne reçoit pas directement les sollicitations du skieur. Aussi, le support ou l'étrier (4) est en appui uniquement sur l'embase (1).According to a characteristic of the invention, the stiffener does not directly receive the stresses of the skier. Also, the support or the bracket (4) is supported only on the base (1).

A cet effet, les extrémités inférieures (44 et 45) des parois latérales du support sont reliées à la surface supérieure (115) de l'embase (1). Avantageusement, la liaison entre le support et l'embase est rigide et obtenue par exemple par collage, par soudage ou tout autre moyen, tel que mécanique.To this end, the lower ends (44 and 45) of the side walls of the support are connected to the upper surface (115) of the base (1). Advantageously, the connection between the support and the base is rigid and obtained for example by gluing, welding or any other means, such as mechanical.

Le support (4) constitue l'élément mécanique de transmission et de distribution des sollicitations du skieur sur l'embase.The support (4) constitutes the mechanical element for transmitting and distributing the stresses of the skier on the base.

Selon le mode de réalisation de la figure 31, le support (4) reçoit à l'avant la fixation avant (51) et s'étend vers l'arrière sur une longueur "L4" jusque sous la fixation arrière (52). Ladite fixation arrière (52) appelée communément talonnière étant elle-même fixée sur la partie arrière dudit support (4).According to the embodiment of FIG. 31, the support (4) receives at the front the front attachment (51) and extends rearward over a length "L4" up to under the rear attachment (52). Said rear attachment (52) commonly called heel being itself fixed on the rear part of said support (4).

La figure 32 représente une variante selon laquelle le ski comprend deux supports (4) espacés l'un de l'autre, un premier support avant (4a) sur lequel est fixée la butée avant (51) de retenue de la chaussure, et un deuxième support ou support arrière (4b) sur lequel est fixée la talonnière (52).FIG. 32 represents a variant according to which the ski comprises two supports (4) spaced from one another, a first front support (4a) on which the front stop (51) for retaining the boot is fixed, and a second support or rear support (4b) on which the heel piece (52) is fixed.

Le support (4, 4a, 4b) peut être un élément injecté en matière plastique ou un profilé métallique, un élément en plastique pultrudé ou extrudé. A titre d'exemple, on peut citer l'emploi des polyamides ou stylémiques pour la composition du support.The support (4, 4a, 4b) can be an injected plastic element or a metal profile, a pultruded or extruded plastic element. By way of example, mention may be made of the use of polyamides or stylemes for the composition of the support.

Bien entendu, le support (4, 4a, 4b) peut être d'une seule et même pièce ou être constitué de différents pièces, voire même constitué par une partie de la fixation (5, 51, 52) correspondante.Of course, the support (4, 4a, 4b) can be in one and the same piece or be made up of different pieces, or even made up of a part of the corresponding fixing (5, 51, 52).

Notons aussi que la liaison (6) entre le support (4, 4a, 4b) et l'embase peut être rigide mais aussi souple. La figure 34 représente une telle variante, et dans laquelle la liaison est réalisée par une interface (60) en matériau souple.Note also that the connection (6) between the support (4, 4a, 4b) and the base can be rigid but also flexible. FIG. 34 shows such a variant, and in which the connection is made by an interface (60) made of flexible material.

La figure 35 est une variante des figures 33 et 34 dans laquelle le raidisseur (2) est intégré dans l'embase (1). Pour cela l'embase (1) se prolonge, de chaque côté, par deux bords latéraux (10, 11) créant ainsi un logement (13) destiné au passage du raidisseur (2). Les dimensions du logement (13) aussi bien horizontale "l5" que verticale "h5" sont supérieures aux dimensions horizontale "l2" et verticale "h2" du raidisseur pour former, comme dans le cas de la variante précédente, un espace "e". Le support (4) se présente, dans ce cas, sous la forme d'une simple plaque solidaire des surfaces supérieures des bords latéraux (10, 11) de l'embase (1).Figure 35 is a variant of Figures 33 and 34 in which the stiffener (2) is integrated in the base (1). For this, the base (1) is extended, on each side, by two lateral edges (10, 11) thus creating a housing (13) intended for the passage of the stiffener (2). The dimensions of the housing (13) both horizontal "l5" and vertical "h5" are greater than the horizontal dimensions "l2" and vertical "h2" of the stiffener to form, as in the case of the previous variant, a space "e" . The support (4) is, in this case, in the form of a simple plate integral with the upper surfaces of the lateral edges (10, 11) of the base (1).

Les figures 36 et 37 représentent une autre variante selon laquelle le raidisseur (2) est lié à l'embase (1) par une articulation transversale (7). A cet effet, on a prévu deux parois latérales de retenue (70, 71) solidaires de l'embase (1). Bien entendu, il peut être possible de prévoir en plus sur cette variante, un support (4) pour les fixations, comme cela est représenté à la figure 38.Figures 36 and 37 show another variant in which the stiffener (2) is linked to the base (1) by a transverse articulation (7). To this end, two lateral retaining walls (70, 71) are provided which are integral with the base (1). Of course, it may be possible to provide, in addition to this variant, a support (4) for the fastenings, as shown in FIG. 38.

A la figure 39, on a représenté une autre variante en vue latérale selon laquelle l'embase (1) comprend dans sa partie centrale (113), une saillie (8) à laquelle est lié le raidisseur (2); la liaison pouvant bien entendu être rigide ou souple et dans ce cas, réalisée par une interface comme dans les réalisations précédentes.In Figure 39, there is shown another variant in side view according to which the base (1) comprises in its central part (113), a projection (8) to which the stiffener (2) is linked; the connection can of course be rigid or flexible and in this case, produced by an interface as in the previous embodiments.

Les figures 40 à 43 montrent d'autres modes de réalisation selon lesquels le raidisseur (2) est lié à l'embase par ses extrémités avant et arrière (209, 210) par des moyens de retenue constitués par des éléments intermédiaires (90, 91) de retenue verticale et latérale. Selon la variante de la figure 40, la surface inférieure (216) du raidisseur (2) n'est pas directement en contact avec la surface supérieure (115) de l'embase (1), alors que dans la variante de la figure 41 il y a contact.Figures 40 to 43 show other embodiments in which the stiffener (2) is connected to the base by its front and rear ends (209, 210) by retaining means constituted by intermediate elements (90, 91 ) vertical and lateral restraint. According to the variant of Figure 40, the lower surface (216) of the stiffener (2) is not directly in contact with the upper surface (115) of the base (1), while in the variant of Figure 41 there is contact.

Dans le premier cas, l'augmentation de la hauteur a notamment pour effet d'augmenter le couple exercé par le raidisseur sur l'embase au niveau des éléments de retenue (90, 91), ce qui a pour conséquence d'augmenter la pression de l'embase sur la neige. On peut également envisager d'exercer une précontrainte du raidisseur tendant à augmenter le couple en utilisant un raidisseur constitué d'une lame maintenue dans sa partie centrale par des moyens de guidage par exemple.In the first case, the increase in height has the particular effect of increasing the torque exerted by the stiffener on the base at the level of the retaining elements (90, 91), which has the consequence of increasing the pressure from the base on the snow. One can also consider exerting a prestressing of the stiffener tending to increase the torque by using a stiffener consisting of a blade held in its central part by guide means for example.

Les moyens de retenue (90, 91) sont constitués chacun par au moins une paroi transversale (92) s'étendant vers le haut et une paroi horizontale (93) s'étendant vers le centre du ski pour constituer un logement inférieur (94) ouvert en direction du centre du ski et fermé latéralement par deux parois latérales (95, 96) de retenue latérale. Les extrémités (209, 210) du raidisseur étant engagées et retenues dans le logement inférieur (94). On pourrait bloquer les deux extrémités dans leur logement correspondant ou bloquer l'une seulement des extrémités (209 ou 210) et permettre le déplacement de l'autre (210 ou 209) dans son logement correspondant, comme cela est représenté aux figures 42c et 42d. A la figure 42c, le jeu "e₁" permet un déplacement "d" de l'extrémité correspondante. Mais le déplacement relatif peut se faire contre l'action d'un système élastique (97), comme cela est représenté à la figure 42d.The retaining means (90, 91) each consist of at least one transverse wall (92) extending upwards and a horizontal wall (93) extending towards the center of the ski to form a lower housing (94) open towards the center of the ski and closed laterally by two side walls (95, 96) of lateral retention. The ends (209, 210) of the stiffener being engaged and retained in the lower housing (94). We could block the two ends in their corresponding housing or block only one of the ends (209 or 210) and allow the displacement of the other (210 or 209) in its corresponding housing, as shown in Figures 42c and 42d . In FIG. 42c, the clearance "e₁" allows a displacement "d" of the corresponding end. But the relative displacement can be done against the action of an elastic system (97), as shown in Figure 42d.

Selon le mode de la figure 40, on peut prévoir que la hauteur du raidisseur soit réglable par un moyen de réglage tel que vissage ou autres tel que représenté à la figure 42c.According to the mode of FIG. 40, provision can be made for the height of the stiffener to be adjustable by an adjustment means such as screwing or the like as shown in FIG. 42c.

Les moyens de retenue longitudinaux et verticaux (90, 91) pourraient aussi être constitués par des systèmes d'articulation (90', 91') comme cela est représenté aux figures 44 et 44a. Ainsi, les extrémités avant (209) et arrière (210) du raidisseur (2) sont liées à l'embase (1) par un axe d'articulation transversal (90, 91), ladite articulation (90', 91') étant retenue à l'embase (1) par un support d'articulation (80) comprenant deux parois latérales de retenue (81, 82).The longitudinal and vertical retaining means (90, 91) could also be constituted by articulation systems (90 ', 91') as shown in Figures 44 and 44a. Thus, the front (209) and rear (210) ends of the stiffener (2) are linked to the base (1) by a transverse articulation axis (90, 91), said articulation (90 ', 91') being retained at the base (1) by a hinge support (80) comprising two lateral retaining walls (81, 82).

L'étrier (4, 4a, 4b) représenté précédemment, a la forme générale d'un "U" renversé, mais il pourrait en être autrement, comme par exemple cela est représenté à la figure 45. Selon cette variante, l'étrier (4) est formé par une pièce ayant la forme générale d'un "U" dont la paroi transversale (46) est disposée entre le raidisseur (2) et son embase (1).The bracket (4, 4a, 4b) shown above has the general shape of an inverted "U", but it could be otherwise, as for example that is represented in FIG. 45. According to this variant, the bracket (4) is formed by a part having the general shape of a "U" whose transverse wall (46) is disposed between the stiffener (2) and its base (1).

Notons aussi que dans les réalisations où seule la partie centrale du raidisseur est liée à l'embase, l'amortissement du ski est réalisé par le frottement des extrémités (209 et 210) du raidisseur sur la surface supérieure de l'embase.Note also that in the embodiments where only the central part of the stiffener is linked to the base, the damping of the ski is achieved by the friction of the ends (209 and 210) of the stiffener on the upper surface of the base.

La figure 46 représente une variante d'un ski dans une coupe transversale selon laquelle il comprend une enveloppe extérieure (200) sous laquelle se trouve l'embase (1) avec son raidisseur (2). L'enveloppe extérieure (200) ayant par exemple un effet décoratif.FIG. 46 represents a variant of a ski in a cross section according to which it comprises an outer casing (200) under which the base (1) is located with its stiffener (2). The outer envelope (200) having for example a decorative effect.

Les figures 47 à 49 montrent une variante de réalisation de l'invention dans laquelle le support (4) comprend une ou plusieurs couches de renforts de façon à compléter les caractéristiques de raideur de l'embase (1). Une telle construction peut être utile notamment lorsque l'on désire réduire la hauteur du complexe embase/support tout en conservant des caractéristiques mécaniques suffisantes.Figures 47 to 49 show an alternative embodiment of the invention in which the support (4) comprises one or more layers of reinforcements so as to complete the stiffness characteristics of the base (1). Such a construction can be useful in particular when it is desired to reduce the height of the base / support complex while retaining sufficient mechanical characteristics.

La figure 47 illustre le cas où l'étrier est muni d'un insert de renfort (470) ayant la forme d'une plaque insérée dans une coque (471) en forme de U renversé. L'insert peut être une plaque métallique en alliage d'aluminium par exemple ou une plaque en matériau composite. Le support (4) peut être obtenu par moulage par injection de la coque (48) en matière plastique. Dans ce cas, on peut bien entendu prévoir que l'insert soit solidarisé à la coque lors de l'injection.FIG. 47 illustrates the case where the stirrup is provided with a reinforcement insert (470) having the form of a plate inserted in a shell (471) in the shape of an inverted U. The insert can be a metal plate of aluminum alloy for example or a plate of composite material. The support (4) can be obtained by injection molding of the plastic shell (48). In this case, one can of course provide that the insert is secured to the shell during injection.

La figure 48 illustre le cas où l'étrier est constitué d'une coque de renfort (480) en forme de U renversé sur laquelle est solidarisée une couche de décor (481). La coque de renfort (480) peut être réalisée d'une ou plusieurs couches de matériaux composites de tout type comme vu précédemment pour la construction des couches de renforts de l'embase.FIG. 48 illustrates the case where the stirrup consists of a reinforcing shell (480) in the shape of an inverted U on which a layer of decoration (481) is secured. The reinforcing shell (480) can be made of one or more layers of composite materials of any type as seen previously for the construction of the reinforcing layers of the base.

De même, la couche de décor (481) peut être en matière plastique telle que polyamide ou autre.Likewise, the decor layer (481) can be made of a plastic material such as polyamide or the like.

La figure 49 illustre la structure interne du ski de l'invention dans la région où s'étend le support (4).FIG. 49 illustrates the internal structure of the ski of the invention in the region where the support extends (4).

Dans ce cas la structure de l'embase (1) comprend, entre autre, une couche de glissement (109), des éléments de renfort inférieurs (110, 111), un noyau (105). Les éléments de renfort supérieurs ne recouvrent pas le noyau, contrairement au cas de la figure 3a et sont remplacés par l'élément de renfort (480) du support (4).In this case the structure of the base (1) comprises, inter alia, a sliding layer (109), lower reinforcing elements (110, 111), a core (105). The upper reinforcement elements do not cover the core, unlike in the case of FIG. 3a and are replaced by the reinforcement element (480) of the support (4).

Bien entendu, le support (4) peut s'étendre plus largement au delà de la zone de montage des fixations, ce qui peut être particulièrement avantageux dans la mesure où sa fonction n'est pas uniquement celle de devoir transmettre les sollicitations du skieur sur l'embase mais également celle d'intervenir dans la distribution de raideur le long du ski.Of course, the support (4) can extend more widely beyond the area for mounting the bindings, which can be particularly advantageous insofar as its function is not only that of having to transmit the stresses of the skier on the base but also that of intervening in the distribution of stiffness along the ski.

Les figures 50 à 52 présentent un mode de réalisation dans lequel le raidisseur est de conception particulière de façon à limiter son encombrement et donc à réduire la hauteur des fixations par rapport à la neige.Figures 50 to 52 show an embodiment in which the stiffener is of a particular design so as to limit its size and therefore reduce the height of the bindings relative to the snow.

Le raidisseur (2) se compose de deux profilés centraux (24, 25) de longueur utile L3 au moins égale ou supérieure à la longueur de la zone prévue pour le montage des fixations (5). De même, les profilés sont espacés l'un de l'autre d'une distance 13 suffisante pour le passage des fixations (5). Ils peuvent être logés latéralement en partie ou totalement dans les logements de forme complémentaire (14) de l'embase de façon à limiter au mieux leur encombrement.The stiffener (2) consists of two central sections (24, 25) of useful length L3 at least equal to or greater than the length of the area provided for mounting the fasteners (5). Similarly, the profiles are spaced from each other by a distance 13 sufficient for the passage of the fasteners (5). They can be housed laterally in part or completely in the complementary shaped housings (14) of the base so as to limit their overall size as much as possible.

Des organes d'accouplement avant et arrière (26, 27) permettent de relier statiquement chacune des extrémités des profilés (24, 25). Chacun de ces organes (26, 27) est fixé par une liaison rigide ou souple à l'embase (1) du ski.Front and rear coupling members (26, 27) make it possible to statically connect each of the ends of the profiles (24, 25). Each of these members (26, 27) is fixed by a rigid or flexible connection to the base (1) of the ski.

Les profilés sont de préférence réalisés en matériau composite par pultrusion et assemblés par moulage, collage ou tout autre moyen aux organes d'accouplements (26, 27).The profiles are preferably made of composite material by pultrusion and assembled by molding, gluing or any other means to the coupling members (26, 27).

Ces derniers peuvent être de toute nature, forme ou structure. On peut prévoir notamment leur constitution en matériau de renfort à base de fibres et résines thermodurcissables par exemple.These can be of any kind, shape or structure. In particular, provision may be made for their reinforcement material based on fibers and thermosetting resins, for example.

Bien entendu l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons, et d'autres variantes sont également possibles sans pour autant sortir du cadre de l'invention.Of course, the invention is not limited to the embodiments described and shown by way of examples, but it also includes all the technical equivalents and their combinations, and other variants are also possible without departing from the scope. of the invention.
