Abstract

The ski has a sole (8), with lower edges (9) and reinforcing (10), a core (14) and an outer surface (13). In its central zone the sole and outer surface form wings on each side that project outwards. An inverted U-shaped piece (17) is placed over the outer surface of the ski and its upper surface (20) forms a rigid platform. The ends of the branches (18) of the U-shaped piece are fixed to the wings or they can be fixed to the edges or the reinforcement. The outer surface of the ski has hollows in which the branches are fixed.

Description

La présente invention a pour objet une planche de glisse sur neige comportant un dispositif pour le montage d'une fixation d'une chaussure. La planche selon l'invention peut être un ski alpin, un ski de fond, un monoski ou un surf, principalement une planche à coque, c'est-à-dire ne comportant pas d'éléments de renforcement latéraux larges ou chants, la coque pouvant, toutefois, être doublée d'un tissu de renfort.The present invention relates to a board for sliding on snow comprising a device for mounting a binding of a shoe. The board according to the invention can be an alpine ski, a cross-country ski cross-country, a monoski or a surf, mainly a hull board, that is to say not having wide side reinforcements or edges, the shell can, however, be lined with a reinforcing fabric.

De façon traditionnelle, un ski est équipé, sur sa face supérieure, d'une fixation pour une chaussure, cette fixation comportant le plus souvent une butée avant et, pour un ski alpin, une talonnière qui sont posées sur la face supérieure du ski et qui sont fixées par vissage dans le corps du ski.Traditionally, a ski is equipped on its face upper, of a binding for a shoe, this binding comprising the more often a front stop and, for an alpine ski, a heel which are placed on the upper face of the ski and which are fixed by screwing in the body of the ski.

Un ski alpin suivant l'invention est très schématiquement constitué d'un ensemble inférieur composé d'une semelle bordée de carres métalliques, et recouverte éventuellement d'un élément de renfort, et d'un ensemble supérieur composé au moins d'un noyau de remplissage, d'un élément de renfort et d'une enveloppe extérieure en une partie sous forme de coque.An alpine ski according to the invention is very schematically consisting of a lower set consisting of a sole bordered by edges metallic, and possibly covered with a reinforcing element, and a upper assembly composed at least of a filling core, a reinforcing element and an outer shell in part in the form hull.

Dans le cas d'un ski à coque, la base de la coque est très souvent constituée de deux bords latéraux en appui sur une partie de leur largeur sur l'ensemble inférieur, c'est-à-dire soit directement sur les carres métalliques, soit sur l'élément de renfort recouvrant ces carres, soit enfin sur un film intermédiaire (film de colle ou film élastique). Dans un tel ski à coque, du fait du déport des carres vers l'extérieur par rapport à la surface d'appui du pied sur le ski, et en raison du fait que les parois latérales de la coque, même associées à des éléments de renforcement, possèdent une rigidité moyenne, l'efficacité de l'appui sur les carres est limitée, notamment dans la zone de montage de la fixation qui subit la transmission des efforts entre le pied du skieur et la neige.In the case of a hull ski, the base of the hull is very often made up of two lateral edges resting on part of their width on the lower assembly, i.e. directly on the edges metal, either on the reinforcing element covering these edges, or finally on an intermediate film (adhesive film or elastic film). In such a ski to hull, due to the offset of the edges outwards relative to the surface support of the foot on the ski, and due to the fact that the side walls of the shell, even associated with reinforcing elements, have a medium stiffness, the effectiveness of the support on the edges is limited, especially in the mounting area of the binding which undergoes the transmission of forces between the skier's foot and the snow.

Pour assurer un bon guidage du ski, il est important que la transmission des efforts entre la chaussure du skieur et la carre d'un ski prenant appui sur la neige soit la plus directe possible. Or, le nombre important des éléments de structure du ski par lesquels doivent transiter les forces entre la neige et la chaussure, constitue des zones de pertes d'efficacité, ceci étant un facteur défavorable pour un bon guidage du ski.To ensure proper guidance of the ski, it is important that the transmission of forces between the skier's shoe and the edge of a ski building on the snow is as direct as possible. The number important structural elements of the ski through which must pass the forces between the snow and the shoe, constitute areas of loss efficiency, this being an unfavorable factor for good guidance of the ski.

Ce phénomène est amplifié lors de l'utilisation d'un dispositif de surélévation pour le montage de la fixation de la chaussure. This phenomenon is amplified when using a heightening for mounting the shoe binding.

Du fait que les skis actuels sont plus étroits au patin, c'est-à-dire dans la zone de montage des fixations, que précédemment, la chaussure déborde de part et d'autre des parois latérales du ski. Il en résulte, lors d'une prise de carres sur une pente forte, que la chaussure peut prendre appui sur la surface de la neige, ce qui se traduit par un déséquilibre du skieur pouvant provoquer sa chute, ou tout au moins lui faire perdre du temps, ce qui est préjudiciable lors d'une compétition.Because the current skis are narrower on the skate, that is to say in the mounting area of the fasteners, than previously, the boot overflows on either side of the side walls of the ski. It results, when taking edges on a steep slope, that the shoe can rest on the surface of the snow, which results in a imbalance of the skier which can cause his fall, or at least him waste time, which is detrimental during a competition.

Pour remédier à cet inconvénient, il a été imaginé de monter, sur la face supérieure du ski, une plaque de surélévation qui permet une angulation plus importante du ski par rapport à la neige avant que la semelle de la chaussure ne prenne appui sur la surface de cette dernière.To remedy this drawback, it was imagined to climb, on the upper face of the ski, a raised plate which allows a greater angulation of the ski compared to the snow before the sole of the shoe is supported on the surface of the latter.

Le document CH 288 757 concerne un ski entièrement métallique comprenant une bande inférieure formant la surface de glissement, qui est sensiblement plane, et une bande supérieure de section transversale de forme générale trapézoïdale, fixée sur la bande inférieure et assurant la résistance à la torsion. Dans la partie centrale du ski, sur la bande supérieure, une plaque d'appui servant au montage de la fixation de la chaussure est fixée par des moyens permettant un déplacement relatif longitudinal. Cette liaison étant coulissante, elle ne permet pas un appui direct, donc efficace, des efforts de l'utilisateur sur les arêtes inférieures du ski.Document CH 288 757 relates to a fully ski metallic comprising a lower strip forming the surface of slip, which is substantially planar, and an upper strip of section transverse in general trapezoidal shape, fixed on the lower band and ensuring resistance to torsion. In the central part of the ski, on the upper band, a support plate used for mounting the fixing of the shoe is fixed by means allowing relative movement longitudinal. This link being sliding, it does not allow a support direct, therefore effective, of the user's efforts on the lower edges ski.

Certaines plaques sont métalliques et fixées simplement sur la face supérieure du ski, formant uniquement des entretoises entre cette face supérieure et la platine de la butée ou de la talonnière.Some plates are metallic and simply attached to the upper face of the ski, forming only spacers between this upper face and the plate of the stop or the heel piece.

Il est également connu de fixer, sur la face supérieure du ski, une plaque de surélévation constituée par une couche de matériau visco-élastique, collée sur le ski, et recouverte d'une plaque de contrainte. Différentes formes d'exécution reposant sur ce concept de base sont envisageables, comme décrit notamment dans les documents FR-A-2 638 651 et FR-A-2 664 823.It is also known to fix, on the upper face of the ski, a raising plate constituted by a layer of visco-elastic material, glued to the ski, and covered with a constraint plate. Different forms of execution based on this basic concept are possible, as described in particular in documents FR-A-2 638 651 and FR-A-2 664 823.

Une telle solution permet d'assurer, outre la surélévation de la chaussure par rapport à la neige, une fonction de débridage de la chaussure par rapport au ski, et également une fonction d'amortissement, notamment par cisaillement de la couche de matériau visco-élastique entre la face supérieure du ski et la plaque de contrainte. Lors de la flexion d'un ski, il se produit un rapprochement de la butée et de la talonnière constitutives de la fixation qui exercent une pression sur la semelle de la chaussure se traduisant par une rigidification du ski dans cette zone et donc par une modification du comportement du ski par rapport à son comportement théorique. Il est donc intéressant d'éviter ce phénomène en assurant un certain débridage de l'ensemble chaussure-fixation par rapport au ski, redonnant à ce dernier une liberté de déformation.Such a solution ensures, in addition to the elevation of the shoe compared to snow, a function of unleashing the shoe compared to skiing, and also a cushioning function, in particular by shearing the layer of visco-elastic material between the upper face of the ski and the stress plate. When bending a skiing, there is an approximation of the toe and the heel components of the binding which exert pressure on the sole of the boot resulting in stiffening of the ski in this area and therefore by a modification of the behavior of the ski compared to its theoretical behavior. It is therefore interesting to avoid this phenomenon by ensuring a certain unclamping of the shoe-binding assembly relative skiing, giving the latter freedom of deformation.

Il est également connu par le document EP-A-0 490 044 de réaliser un ski constitué par un premier ensemble inférieur ou embase et un deuxième ensemble supérieur ou raidisseur fixé sur l'embase. Le raidisseur joue le rôle d'une plateforme de longueur importante sur laquelle est montée la fixation de la chaussure.It is also known from document EP-A-0 490 044 of make a ski consisting of a first lower assembly or base and a second upper assembly or stiffener fixed on the base. The stiffener plays the role of a platform of considerable length on which is mounted the binding of the shoe.

Dans les solutions évoquées précédemment, la fixation est montée sur un élément lui-même fixé sur la face supérieure du ski. Or, pour assurer un meilleur guidage possible du ski, il est important que la transmission des efforts entre la carre d'un ski, prenant appui sur la neige, et la chaussure du skieur soit la plus directe possible. Or, l'interposition d'une plateforme de surélévation augmente le nombre des éléments par lesquels doivent transiter les forces entre la neige et la chaussure, ce qui constitue un facteur défavorable pour un bon guidage du ski.In the solutions mentioned above, the fixation is mounted on an element itself fixed on the upper face of the ski. Gold, to ensure the best possible guidance of the ski, it is important that the transmission of forces between the edge of a ski, supported on the snow, and the skier's shoe is as direct as possible. The interposition of a raised platform increases the number of elements by which must pass the forces between the snow and the shoe, which is an unfavorable factor for good ski guidance.

Le document FR-A-2 590 179 décrit un ski de fond contenant une plaque de stabilisation disposée à l'intérieur du ski, sous la paroi supérieure de celui-ci, et dont les extrémités sont cintrées en direction de la semelle. Cette plaque comporte, au moins le long de l'un de ses bords longitudinaux, un prolongement vers le bas disposé à l'intérieur du ski et formant un angle de 5 à 45° avec la paroi latérale correspondante du ski.Document FR-A-2 590 179 describes a cross-country ski containing a stabilization plate placed inside the ski, under the wall upper part thereof, and the ends of which are bent in the direction of the sole. This plate has, at least along one of its edges longitudinal, a downward extension arranged inside the ski and forming an angle of 5 to 45 ° with the corresponding side wall of the ski.

Le document EP-A-0 490 043 considéré comme l'état de la technique plus proche concerne un ski comprenant un corps sur lequel est fixé, par ses extrémités, un élément allongé formant raidisseur. Une plateforme, de section en U, et destinée au montage d'une fixation coiffe le raidisseur et repose sur le corps du ski par les extrémités de ses branches (cf. en particulier les figures 1-6).Document EP-A-0 490 043 considered to be the closest state of the art relates to a ski comprising a body on which is fixed, by its ends, an elongated element forming stiffener. A platform, U-shaped, and intended for mounting a fixation covers the stiffener and rests on the body of the ski at the ends of its branches (see in particular Figures 1-6).

Le document EP-A-0 563 569 concerne un ski de même structure générale que celui décrit dans le document EP-A-0 490 043, mais dans lequel le raidisseur est réalisé en deux parties.Document EP-A-0 563 569 relates to a ski of the same general structure as that described in document EP-A-0 490 043, but in which the stiffener is made in two parts.

Le document EP-A-0 577 947 concerne un ski de même structure générale que ceux décrits dans les deux documents qui précédent, mais dans lequel l'élément raidisseur est constitué par une nervure centrale et longitudinale.The document EP-A-0 577 947 relates to a ski of the same general structure than those described in the two documents which previous, but in which the stiffening element is constituted by a central and longitudinal rib.

Le but de l'invention est de fournir une planche de glisse à coque équipée d'un dispositif pour le montage de la fixation d'une chaussure assurant une transmission la plus directe possible des efforts entre la neige et la chaussure du skieur.The object of the invention is to provide a sliding board for shell fitted with a device for mounting the attachment of a shoe ensuring the most direct transmission of forces between the snow and the skier's shoe.

est caractérisée en ce que chaque élément inférieur est disposé à l'extérieur de la planche et prend appui directement sur les arêtes inférieures de la planche, ou recouvre latéralement la paroi de la partie inférieure de la planche et en ce que, dans les zones comportant les éléments inférieurs, les éléments de liaison et l'élément supérieur, la coque présente des décrochements vers l'intérieur, ménageant des passages pour les éléments inférieurs, les éléments de liaison, et éventuellement l'élément supérieur. L'effort exercé par le pied du skieur est transmis directement au travers du dispositif pour le montage de la fixation, composé de la plateforme, de la liaison et d'au moins une patte, aux arêtes inférieures du ski. Dans un tel cas, la force ne transite donc pas par la structure du ski donc par les différents composants de celui-ci susceptibles d'absorber une partie de cette force. La partie supérieure ou plateforme est soit surélevée par rapport à la surface supérieure de la coque, soit au contact de cette dernière, soit enfin encastrée dans un logement prévu dans cette surface supérieure.To this end, the board it concerns, comprising a device for mounting a shoe binding, this board comprising a lower wall intended to bear on the snow, constituted by a sole bordered by lower edges and possibly associated a reinforcing element, an upper wall parallel to the lower wall and two side walls connecting the lower and upper walls, these different walls delimiting a volume filled by a filling core, the upper wall and the side walls being constituted by a shell associated with a reinforcing element and whose lateral edges bear on the lower edges of the board, the board being equipped in its central part or pad area of the device for mounting the binding for a shoe consisting of:
  • at least one lower leg-shaped element located on at least one side of the board and resting on it,
  • at least one upper element which, placed above the upper wall or at the level of this wall, forms a rigid platform for mounting the fastener, and
  • at least one connecting element between each lower element and each upper element, arranged outside the body of the ski, the assembly: lower element-connecting element and upper element being rigid, that is to say non-deformable,
is characterized in that each lower element is arranged outside the board and bears directly on the lower edges of the board, or laterally covers the wall of the lower part of the board and in that, in the areas comprising the lower elements, the connecting elements and the upper element, the shell has inward recesses, providing passages for the lower elements, the connecting elements, and possibly the upper element. The force exerted by the skier's foot is transmitted directly through the device for mounting the binding, composed of the platform, the connection and at least one tab, at the lower edges of the ski. In such a case, the force therefore does not pass through the structure of the ski, therefore through the various components of it capable of absorbing part of this force. The upper part or platform is either raised relative to the upper surface of the shell, or in contact with the latter, or finally embedded in a housing provided in this upper surface.

Suivant une première forme d'exécution, dans chaque zone de la coque destinée à recevoir un élément inférieur en forme de patte, l'ensemble inférieur délimite une surface horizontale servant à l'appui d'un élément inférieur en forme de patte.According to a first embodiment, in each zone of the shell intended to receive a lower leg-shaped element, the lower assembly defines a horizontal surface used to support a lower leg-shaped element.

Suivant une seconde forme d'exécution, l'ensemble inférieur présente un décrochement supprimant localement la surface horizontale et l'élément inférieur en forme de patte constitue lui-même l'arête inférieure du ski. According to a second embodiment, the lower assembly has a recess locally removing the horizontal surface and the lower leg-shaped element itself constitutes the lower edge ski.

Selon une forme d'exécution de ce ski, les éléments inférieurs, de liaison et la plateforme sont constitués par au moins une pièce monobloc en forme générale de U renversé.According to one embodiment of this ski, the lower elements, of connection and the platform consist of at least one part monobloc in general shape of inverted U.

Selon une autre forme d'exécution, les éléments inférieur, de liaison et supérieur sont constitués par une pièce monobloc de section en forme générale de L, dont une aile est associée à la face supérieure du ski et dont l'autre aile est associée à la paroi latérale intérieure du ski, si l'on considère les deux skis d'une même paire placés l'un à côté de l'autre.According to another embodiment, the lower elements, of connection and upper are constituted by a monobloc piece of section in general shape of L, of which a wing is associated with the upper face of the ski and whose other wing is associated with the inner side wall of the ski, if we consider the two skis of the same pair placed side by side.

L'aile supérieure peut être en contact avec la face supérieure du ski ou disposée au-dessus de celle-ci, avec interposition ou non d'une couche de matériau visco-élastique. L'aile verticale est avantageusement fixée par collage contre la paroi latérale correspondante du ski.The upper wing can be in contact with the upper face of the ski or arranged above it, with or without the interposition of a layer of visco-elastic material. The vertical wing is advantageously fixed by gluing against the corresponding side wall of the ski.

Dans le cas d'une planche comportant une coque dont les parois latérales sont inclinées de haut en bas et de l'intérieur vers l'extérieur, dans les zones comportant les éléments inférieurs et les éléments de liaison, l'inclinaison des parois latérales de la coque varie dans un sens de rapprochement avec la perpendiculaire au plan de la semelle, et est associée à une réduction de la largeur de la partie inférieure du corps du ski, pour permettre une plus grande surface d'appui des éléments inférieurs sur l'ensemble inférieur du ski.In the case of a board comprising a hull whose side walls are tilted up and down and from the inside towards outside, in the areas comprising the lower elements and the connecting elements, the inclination of the side walls of the shell varies in a direction of approximation with the perpendicular to the plane of the sole, and is associated with a reduction in the width of the lower body of the ski, to allow a greater support surface for the elements lower on the lower ski assembly.

Selon une forme d'exécution de ce ski, le ou les éléments inférieurs le ou les éléments de liaison et l'élément supérieur s'étendent sur toute la longueur de montage de la fixation de la chaussure, l'élément supérieur formant une plateforme continue. Suivant la configuration de l'ensemble monobloc, les éléments inférieurs et de liaison sont confondus.According to one embodiment of this ski, the element or elements lower the connecting element (s) and the upper element extend over the entire mounting length of the shoe binding, the element upper forming a continuous platform. Depending on the configuration of the one-piece assembly, the lower and connecting elements are combined.

Dans la mesure où le ski comporte une pièce monobloc de section en U, les éléments de liaison et inférieurs présentent des fentes réparties sur sa longueur, débouchant dans son bord inférieur, sensiblement perpendiculairement à celui-ci. Ces fentes permettent au dispositif pour le montage des fixations de fléchir longitudinalement, évitant ainsi de brider le ski dans la zone de fixation, comme tel serait le cas si les éléments de liaison étaient continus et s'étendaient sur toute la longueur du dispositif.Insofar as the ski comprises a one-piece piece of U-section, connecting and lower elements have slots spread over its length, opening into its lower edge, substantially perpendicular to it. These slots allow the device for mounting the fasteners to flex longitudinally, thus avoiding clamping the ski in the binding area, as would be the case case if the connecting elements were continuous and spanned the entire length of the device.

Selon une autre forme d'exécution de ce ski, dans le cas d'un ski alpin, les éléments inférieurs, le ou les éléments de liaison et l'élément supérieur sont disposés suivant deux sous-ensembles distincts décalés longitudinalement, dont celui avant sert au montage de la butée avant et dont celui arrière sert au montage de la talonnière de la fixation.According to another embodiment of this ski, in the case of a Alpine skiing, the lower elements, the connecting element (s) and the element upper are arranged in two distinct offset sub-assemblies longitudinally, the front one of which is used for mounting the front stop and including the rear one for mounting the heel of the binding.

Suivant une possibilité, le dispositif de surélévation est asymétrique par rapport au plan longitudinal médian du ski. Par exemple, le nombre et la position longitudinale des différents éléments de liaison et inférieurs sont différents le long des deux côtés de la plateforme.According to one possibility, the raising device is asymmetrical with respect to the median longitudinal plane of the ski. For example, the number and the longitudinal position of the various connecting elements and lower are different along the two sides of the platform.

Suivant une autre forme d'exécution, la plateforme est de longueur supérieure à celle des éléments inférieurs en forme de pattes, et dépasse longitudinalement de part et d'autre de celles-ci.According to another embodiment, the platform is to length greater than that of the lower legs-shaped elements, and protrudes longitudinally on either side of them.

Avantageusement, dans le cas où la plateforme est disposée au-dessus de la face supérieure du ski, une couche de matériau visco-élastique est interposée entre la face supérieure du ski et la plateforme.Advantageously, in the case where the platform is arranged above the upper face of the ski, a layer of visco-elastic material is interposed between the upper face of the ski and the platform.

La plateforme peut soit servir au montage d'une fixation standard, par exemple vissée, soit être constituée par une glissière formant l'embase recevant le corps de la fixation de chaussure, butée ou talonnière. Cette seconde solution permet de limiter le nombre des pièces constitutives de l'ensemble, puisqu'une seule pièce joue à la fois le rôle de plateforme et le rôle de la glissière longitudinale, dans laquelle est montée réglable, et de façon connue, le corps de fixation.The platform can either be used for mounting a binding standard, for example screwed, or be constituted by a slide forming the base receiving the body of the shoe binding, stopper or heel. This second solution makes it possible to limit the number of parts constitutive of the whole, since a single piece plays both the role of platform and the role of the longitudinal slide, in which is mounted adjustable, and in known manner, the fixing body.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, plusieurs formes d'exécution de ce ski :

    • In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended diagrammatic drawing representing, by way of nonlimiting examples, several embodiments of this ski:
  • Figure 1 is a perspective view of a first ski equipped with a platform extending throughout the mounting area of the bindings;

    • La figure 1 représente un ski alpin 2 comportant une spatule 3, un talon 4 et une partie centrale ou zone de patin 5 destinée à recevoir une fixation de chaussure constituée par une butée 6 et une talonnière 7. Le ski dont il s'agit comporte, comme montré plus spécialement à la figure 4, un ensemble inférieur composé d'une semelle de glissement 8, des carres métalliques longitudinales 9 disposées de part et d'autre de la semelle, et d'un renfort inférieur 10. La partie supérieure du ski, c'est-à-dire la paroi supérieure et les parois latérales de celui-ci sont délimitées par une coque 12 dont la face interne est associée à un élément 13 de renforcement. Le noyau du ski est par exemple réalisé en mousse de matière synthétique expansée 14. Comme cela ressort du dessin, la coque 12 présente une paroi supérieure 15 qui, vue en section, est sensiblement parallèle à la semelle de glissement 8, et deux parois latérales 16 inclinées chacune de haut en bas, c'est-à-dire de la paroi supérieure 15 vers la semelle 8 et de l'intérieur vers l'extérieur. Dans la partie centrale du ski, la paroi supérieure 15 possède une largeur L. Dans cette partie centrale, et plus précisément dans la zone de montage de la fixation, cette largeur L demeure constante, mais l'inclinaison des parois latérales 16 varie en se rapprochant de la perpendiculaire au plan de la semelle, avec un rétrécissement de la largeur du corps du ski, dans la partie inférieure de celui-ci. Comme montré à la figure 5, il résulte de cette forme le ménagement d'ailes horizontales de part et d'autre du corps du ski. Ces deux ailes horizontales servent, dans la forme d'exécution représentée à la figure 1, au montage d'une pièce 17 en forme de U renversé, dont les extrémités 18 des branches forment des éléments inférieurs destinés à prendre appui sur les ailes horizontales, et dont les branches 19 constituent des éléments de liaison avec un élément supérieur 20 formant une plateforme pour le montage de la butée 6 et de la talonnière 7. Les évidements ménagés latéralement au niveau du corps du ski permettent le passage des branches 19 sans que celles-ci ne débordent de part et d'autre de la semelle du ski. Si, dans la forme d'exécution représentée à la figure 5, les extrémités inférieures 18 des branches 19 prennent appui sur la coque, elles pourraient tout aussi bien prendre appui directement sur l'ensemble inférieur, c'est-à-dire sur les carres 9 ou sur des éléments de renforcement, tels que l'élément de renforcement 10 ou l'élément de renforcement 13. Afin de favoriser la flexibilité du dispositif de surélévation, les branches 19 constitutives des éléments intermédiaires comportent des fentes 22 débouchant vers le bas. Il serait également possible d'alléger totalement les branches 19 en ne conservant que des parties 23 formant piliers aux extrémités.FIG. 1 represents an alpine ski 2 comprising a tip 3, a heel 4 and a central part or pad area 5 intended to receive a shoe binding consisting of a stop 6 and a heel piece 7. The ski in question comprises, as shown more especially in the FIG. 4, a lower assembly composed of a sliding sole 8, longitudinal metal edges 9 arranged on either side of the sole, and a lower reinforcement 10. The upper part of the ski, that is to say the upper wall and the side walls thereof are delimited by a shell 12 whose internal face is associated with an element 13 of enhancement. The core of the ski is for example made of foam expanded synthetic material 14. As can be seen from the drawing, the shell 12 has an upper wall 15 which, seen in section, is substantially parallel to the sliding sole 8, and two inclined side walls 16 each from top to bottom, i.e. from the top wall 15 towards the sole 8 and from the inside to the outside. In the central part of the ski, the upper wall 15 has a width L. In this central part, and more precisely in the mounting area of the binding, this width L remains constant, but the inclination of the side walls 16 varies in approaching the perpendicular to the plane of the sole, with a narrowing of the width of the ski body, in the lower part of this one. As shown in Figure 5, it follows from this form the provision of horizontal wings on either side of the ski body. These two horizontal wings serve, in the embodiment shown in the Figure 1, mounting a part 17 in the form of an inverted U, the ends 18 of the branches form lower elements intended for lean on the horizontal wings, and whose branches 19 constitute connecting elements with an upper element 20 forming a platform for mounting the stopper 6 and the heel piece 7. The recesses made laterally at the level of the ski body allow the passage of the branches 19 without the latter overflowing from the side and on the other side of the ski sole. If, in the embodiment shown in Figure 5, the lower ends 18 of the branches 19 are supported on the hull, they could just as easily rest directly on the lower assembly, that is to say on the edges 9 or on elements of reinforcement, such as the reinforcement element 10 or the reinforcement element reinforcement 13. In order to favor the flexibility of the heightening, the branches 19 constituting the intermediate elements have slots 22 opening downwards. It would also possible to completely lighten the branches 19 while keeping only parts 23 forming pillars at the ends.

    La figure 3 représente une variante d'exécution des figures 1 et 2, dans laquelle le corps du ski comporte deux parties 24 rétrécies, au niveau de chacune desquelles est disposée une pièce formant une petite plateforme, respectivement 25 et 25a pour le montage de la butée 6 et de la talonnière 7. La pièce 25 est similaire à la pièce 17 définie précédemment, à la différence près que ses dimensions sont réduites. La pièce 25a est constituée par une glissière ouverte vers le haut, formant embase pour le montage réglable longitudinalement du corps de la talonnière de la fixation.FIG. 3 represents an alternative embodiment of FIGS. 1 and 2, in which the ski body has two narrowed parts 24, at level of each of which is arranged a piece forming a small platform, respectively 25 and 25a for mounting the stop 6 and the heel piece 7. The part 25 is similar to the part 17 defined previously, except that its dimensions are reduced. The part 25a is constituted by a slide open upwards, forming base for the longitudinally adjustable mounting of the body of the heel piece of the binding.

    La figure 6 représente une vue de dessus de la partie centrale d'un autre ski comportant un dispositif de surélévation asymétrique par rapport au plan longitudinal médian du ski, constitué par une plateforme 32 prenant appui sur les carres par l'intermédiaire de deux pattes 40 situées à proximité de ses deux extrémités le long de l'un des bords du ski, et par l'intermédiaire d'une seule patte 42 située sensiblement à mi-longueur de l'autre bord du ski. Les deux dispositifs correspondant aux deux skis d'une même paire étant symétriques par rapport à un plan longitudinal médian passant entre les deux skis, il est possible de modifier le comportement des skis en intervertissant les deux skis d'une même paire. Si les bords comportant chacun deux pattes 40 sont situés du côté intérieur, les skis possèdent un bon comportement dans des virages à grand rayon de courbure, comme tel est le cas en slalom géant, tandis que si les bords comportant chacun une patte 42 sont situés du côté intérieur, les skis possèdent un bon comportement dans des virages à plus faible rayon de courbure, comme tel est le cas en slalom spécial.Figure 6 shows a top view of the central part of another ski comprising an asymmetrical raising device by relation to the median longitudinal plane of the ski, constituted by a platform 32 bearing on the edges by means of two legs 40 located near its two ends along one of the edges of the ski, and by means of a single tab 42 located substantially at mid-length on the other side of the ski. The two devices corresponding to two skis of the same pair being symmetrical with respect to a plane longitudinal median passing between the two skis, it is possible to modify the behavior of the skis by reversing the two skis of the same pair. If the edges each having two legs 40 are located on the side inside, the skis have good behavior when cornering large radius of curvature, as is the case in giant slalom, while if the edges each having a tab 42 are located on the inside, the skis have good behavior in lower turns radius of curvature, as is the case in special slalom.

    La figure 7 représente un autre ski, vu de côté, dans lequel l'élément de surélévation, vu en coupe transversale, a une forme de U, composé d'une plateforme 20 associée par un élément de liaison 43 à des éléments inférieurs 44 en forme de pattes, en appui sur les carres, chaque élément 44 centré sur la plateforme 17 étant de longueur inférieure à la longueur de cette dernière. La plateforme 17 est donc montée en porte-à-faux par rapport aux pattes 44.Figure 7 shows another ski, seen from the side, in which the raising element, seen in cross section, has a U shape, composed of a platform 20 associated by a connecting element 43 with lower elements 44 in the form of legs, bearing on the edges, each element 44 centered on the platform 17 being of length less than the length of the latter. Platform 17 is therefore mounted cantilevered with respect to the legs 44.

    La figure 8 représente une autre forme d'exécution de ce ski, dans laquelle les mêmes éléments sont désignés par les mêmes références que précédemment. Dans ce cas, le ski est équipé dans sa zone de patin d'une pièce 45 en forme de L, dont une aile 46 prend appui sur la face supérieure du ski et dont l'autre aile 47 est disposée verticalement le long de l'une des parois latérales du ski et prend appui sur l'ensemble inférieur. L'aile 47 est située du côté de la paroi intérieure, si l'on considère une paire de ski dans laquelle les deux skis sont posés à plat l'un à côté de l'autre.FIG. 8 represents another embodiment of this ski, in which the same elements are designated by the same references than before. In this case, the ski is equipped in its skate area of an L-shaped part 45, one wing 46 of which bears on the face upper of the ski and the other wing 47 of which is arranged vertically along from one of the side walls of the ski and rests on the lower assembly. Wing 47 is located on the side of the inner wall, if we consider a pair of skis in which the two skis are placed flat one next to the other.

    La figure 9 représente une variante d'exécution du dispositif de figure 8, dans laquelle une couche 48 de matériau visco-élastique est interposée entre la face supérieure du ski et l'aile 46 de la pièce 45.Figure 9 shows an alternative embodiment of the Figure 8, in which a layer 48 of visco-elastic material is interposed between the upper face of the ski and the wing 46 of the part 45.

    La figure 10 représente une autre forme d'exécution de ce ski, comportant une pièce 49 de section en U, similaire à la pièce 17 de figure 5. Dans ce cas, l'une des branches verticales 50 du U repose sur l'ensemble inférieur du ski, tandis que l'autre branche 52 du U est plaquée contre l'ensemble inférieur, et constitue, par son extrémité inférieure 52a, l'arête inférieure rigide d'un ski de fond ou la carre du ski lorsqu'il s'agit d'un ski alpin comportant des carres, comme tel est le cas à la figure 10.FIG. 10 represents another embodiment of this ski, comprising a part 49 of U-shaped section, similar to the part 17 of figure 5. In this case, one of the vertical branches 50 of the U rests on the lower assembly of the ski, while the other branch 52 of the U is plated against the lower assembly, and constitutes, by its lower end 52a, the rigid lower edge of a cross-country ski or the edge of the ski when it is an alpine ski comprising edges, as is the case in FIG. 10.

    La figure 11 représente, en vue de dessus, un ski 53 comportant une coque dont les parois latérales sont sensiblement perpendiculaires à la semelle du ski et à la face supérieure de celui-ci. Dans ce cas, dans la zone de patin, la coque comporte deux décrochements 54 vers l'intérieur destinés chacun à permettre le passage des pattes et des éléments de liaison de celles-ci avec la paroi supérieure ou plateforme destinée au montage de la fixation.Figure 11 shows, in top view, a ski 53 comprising a shell whose side walls are substantially perpendicular to the sole of the ski and to the upper face thereof. In this case, in the skate area, the hull has two 54 inwards recesses each intended to allow passage legs and connecting elements thereof with the upper wall or platform for mounting the binding.

    En outre, ce ski présente un dégagement 55 permettant le logement de l'extrémité inférieure 52a du dispositif 49.In addition, this ski has a clearance 55 allowing the housing of the lower end 52a of the device 49.

    Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un ski équipé d'une plateforme, et dont la structure est telle que la transmission des efforts entre la neige et la fixation de la chaussure est effectuée le plus directement possible aux arêtes inférieures du ski.As is apparent from the above, the invention provides a great improvement to the existing technique by providing an equipped ski of a platform, and whose structure is such that the transmission of efforts between the snow and the binding of the shoe is carried out the most directly possible at the lower edges of the ski.

    Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de ce ski, décrites ci-dessus à titre d'exemples, elle en embrasse au contraire toutes les variantes.It goes without saying that the invention is not limited only to embodiments of this ski, described above by way of examples, it on the contrary embraces all variants.

    C'est ainsi notamment que l'élément supérieur ou plateforme pourrait être encastré dans la face supérieure du ski, ou encore que l'invention pourrait viser un autre type de planche de glisse, telle que ski de fond, monoski ou surf, sans que l'on sorte pour autant du cadre de l'invention.This is especially how the upper element or platform could be built into the upper side of the ski, or the invention could target another type of gliding board, such as skiing cross-country, monoski or surf, without leaving the framework of the invention.
