Description

L'invention concerne une planche de glisse pour la pratique des sports d'hiver. Particulièrement l'invention concerne une planche de glisse pour la pratique de nouvelles activités de glisse sur neige, comme par exemple le freestyle ou le freeride.The invention relates to a board for gliding for the practice of winter sports. In particular, the invention relates to a gliding board for the practice of new snow sliding activities, such as for example freestyle or freeride.

Le freestyle consiste notamment en la réalisation de figures, de sauts.Freestyle consists in particular in the realization of figures, jumps.

Le freeride est une pratique libre et variée de la montagne. Le pratiquant descend les pentes sur les pistes ou hors des pistes dans tout type de neige comme par exemple des neiges poudreuses. Pour la pratique en neige poudreuse il est connu des skis à queue d'hirondelle. Un exemple de ce type de ski est décrit dans le document DE 27 04 858 . Ce type de ski est particulièrement adapté à l'utilisation en neige poudreuse ou neige fraîche. Outre le fait qu'il apporte une certaine flexibilité, le ski à queue d'hirondelle a également pour effet de faciliter la déformation en torsion du ski tout en maintenant le ski à plat. En effet grâce à la possibilité de mouvement l'une par rapport à l'autre qu'ont les deux extrémités arrière du ski, ces dernières pourront plus facilement se maintenir à plat sur le neige. C'est ce maintien à plat des extrémités arrière du ski qui donnent à ce genre de ski une meilleure sensation de « slide », c'est-à-dire une meilleure sensation de déraper. Ces skis ont, cependant de nombreuses limites d'une part car ils sont très souples. Ainsi la déformation en flexion dans la zone arrière est très importante. C'est pourquoi ces skis sont peu recommandés pour une utilisation freestyle voir pour une utilisation freeride. En réception de sauts ces skis n'offriront pas assez de support à l'utilisateur.Freeride is a free and varied practice of the mountain. The practitioner descends the slopes on the slopes or off the slopes in any type of snow such as powdery snow. For practice on powder snow it is known swallowtail skis. An example of this type of ski is described in the document DE 27 04 858 . This type of ski is particularly suitable for use in powder snow or fresh snow. In addition to providing flexibility, the swallowtail ski also facilitates torsional deformation while keeping the ski flat. Indeed, thanks to the possibility of movement relative to each other that have the two rear ends of the ski, they can more easily stay flat on the snow. It is this flat support of the rear ends of the ski that gives this kind of ski a better feeling of "slide", that is to say, a better feeling of skidding. These skis have, however, many limitations on the one hand because they are very flexible. Thus the bending deformation in the rear zone is very important. This is why these skis are not recommended for freestyle use or freeride use. In reception jumps these skis will not offer enough support to the user.

Le document FR 2 794 374 décrit un ski à géométrie variable. Des moyens d'expansion sont placés dans des entailles ménagées à l'arrière, à l'avant ou dans la partie centrale. Ces moyens d'expansion peuvent rigidifier le ski au niveau des entailles.The document FR 2 794 374 describes a ski with variable geometry. Expansion means are placed in notches in the rear, front or in the central part. These expansion means can stiffen the ski at the notches.

Le but de la présente invention est d'améliorer le fonctionnement des skis à queue d'hirondelle.The object of the present invention is to improve the operation of the swallowtail skis.

Un autre but de la présente invention est de fournir un ski qui soit rigide pour la pratique freeride ou freestyle notamment pour améliorer la réception des sauts.Another object of the present invention is to provide a ski that is rigid for freeride or freestyle practice in particular to improve the reception of jumps.

Un autre but de la présente invention est de prévoir un ski tolérant en torsion dans sa partie arrière.Another object of the present invention is to provide a ski tolerant torsion in its rear part.

Un autre but de la présente invention est de prévoir un ski qui améliore la sensation de glisse et notamment qui améliore la sensation de slide en fin de virage.Another object of the present invention is to provide a ski which improves the feeling of sliding and in particular which improves the feeling of slide at the end of the turn.

Un autre but de la présente invention est de prévoir une planche de glisse qui offre de la modularité au fabricant, au détaillant ou à l'utilisateur.Another object of the present invention is to provide a gliding board that offers modularity to the manufacturer, the retailer or the user.

Un autre but de la présente invention est de prévoir une planche de glisse ayant une semelle de glisse dont la forme n'est pas plane, celle-ci pouvant être convexe ou concave.Another object of the present invention is to provide a gliding board having a gliding sole whose shape is not flat, it may be convex or concave.

Enfin un autre but de la présente invention est de prévoir une méthode de fabrication d'un ski qui possède les caractéristiques précédentes. Notamment la présente invention poursuit le but de prévoir une méthode d'usinage d'un ski ne possédant pas des surfaces de glisse planes.Finally, another object of the present invention is to provide a method of manufacturing a ski that has the above characteristics. In particular, the present invention has the aim of providing a method of machining a ski that does not have planar sliding surfaces.

The invention will be better understood on reading the description attached to the drawing in which:
  • The figure 1 is a perspective view of a gliding board according to a first embodiment of the invention.
  • The figure 2 is an exploded perspective view of the various components of the gliding board described in figure 1 .

La figure 1 décrit une vue en perspective d'une planche de glisse selon un premier mode de réalisation de l'invention. Celle-ci comprend une ébauche de planche de glisse 15 et un insert de rigidification 8. Nous verrons plus loin que l'ébauche de planche de glisse 15 est réalisée comme un ski fini et que ce n'est qu'à la fin du processus de réalisation de la planche de glisse qu'est inséré l'insert de rigidification 8.The figure 1 describes a perspective view of a gliding board according to a first embodiment of the invention. This comprises a blank board 15 and a stiffening insert 8. We will see later that the blank board 15 is made as a finished ski and that it is only at the end of the process embodiment of the gliding board that is inserted the stiffening insert 8.

L'extrémité arrière de l'ébauche de planche de glisse 15 comprend une entaille allongée 16. Ainsi le contour de l'extrémité de l'ébauche de planche de glisse 15 est celui d'une planche de glisse dite à queue d'hirondelle. A l'intérieur de l'entaille allongée 16 ménagée dans l'extrémité arrière de l'ébauche de planche de glisse 15 est inséré l'insert de rigidification 8.The rear end of the gliding board blank 15 comprises an elongated notch 16. Thus the contour of the end of the gliding board blank 15 is that of a so-called swallow-tail gliding board. Inside the elongated notch 16 formed in the rear end of the gliding board blank 15 is inserted the stiffening insert 8.

L'insert de rigidification comprend deux portions, une portion antérieure 11 et une portion postérieure 12. La portion antérieure 11 est intégralement insérée et logée à l'intérieur de l'entaille allongée 16 de l'ébauche de planche de glisse 15. La portion postérieure 12 de l'insert de rigidification 8 fait saillie de l'entaille allongée et constitue ainsi l'extrémité arrière de la planche de glisse 1 une fois celle-ci terminée.The stiffening insert comprises two portions, an anterior portion 11 and a posterior portion 12. The anterior portion 11 is integrally inserted and housed within the elongated notch 16 of the gliding board blank 15. The portion posterior 12 of the stiffening insert 8 protrudes from the elongate notch and thus constitutes the rear end of the gliding board 1 once it is complete.

La fabrication d'une planche de glisse selon l'invention consiste en la réalisation d'une ébauche de planche de glisse comportant une entaille allongée puis en l'insertion d'un insert de rigidification dans ladite entaille allongée. L'ébauche de planche de glisse peut être réalisée comme le serait une planche de glisse selon l'art antérieur. C'est-à-dire selon tout procédé de fabrication connu. Actuellement les deux procédés couramment utilisé sont la technologie collée, où tous les éléments constitutifs de la planche de glisse sont placés dans un moule qui est placé sous presse et chauffé, ou la technologie injectée, où tout les éléments constitutifs, sauf le noyau, sont placés dans un moule qui est ensuite fermé et à l'intérieur duquel est injecté une mousse qui en durcissant constituera le noyau. Il existe également d'autres procédés hybrides de ces deux procédés dans lesquels une partie du noyau est préparé avant d'être mis dans le moule, tandis que le reste du noyau est réalisé par injection.The manufacture of a gliding board according to the invention consists in producing a gliding board blank comprising an elongated notch and then inserting a stiffening insert into said elongated notch. The rough glide board can be made as would be a gliding board according to the prior art. That is, according to everything known manufacturing process. Currently the two commonly used methods are glue technology, where all the components of the gliding board are placed in a mold that is pressed and heated, or injected technology, where all the constituent elements, except the core, are placed in a mold which is then closed and inside which is injected a foam which hardening will form the core. There are also other hybrid methods of these two processes in which part of the core is prepared before being put in the mold, while the rest of the core is made by injection.

Les figures 2 et 3 décrivent une méthode de fabrication de la planche de glisse selon l'invention.The figures 2 and 3 describe a method of manufacturing the gliding board according to the invention.

La méthode de fabrication d'une planche de glisse selon l'invention comprend les étapes suivantes.The method of manufacturing a gliding board according to the invention comprises the following steps.

Tout d'abord il y a les différentes étapes de préparation des différents constituants de la planche de glisse selon l'invention. Parmi ces étapes, il y a l'étape de préparation d'un sous-ensemble supérieur 2, l'étape de préparation d'un sous-ensemble inférieur 3, l'étape de préparation d'un noyau intercalaire 4, l'étape de préparation d'une entretoise de finition 18, l'étape de préparation d'un insert de rigidification 8.First of all there are the different stages of preparation of the various constituents of the gliding board according to the invention. Among these steps, there is the step of preparing an upper subset 2, the step of preparing a lower subset 3, the step of preparing an intermediate core 4, the step for preparing a finishing spacer 18, the step of preparing a stiffening insert 8.

Dans la suite de la description nous ne rentrerons pas dans le détail de toutes les étapes de préparation dont certaines sont largement connues dans l'état antérieur.In the rest of the description we will not go into detail of all the preparation steps, some of which are widely known in the previous state.

Parmi les étapes connues et non décrite ici de façon détaillée, il y a les étapes de préparation des sous-ensembles supérieurs, les étapes de préparation des sous-ensembles inférieurs, et les étapes de préparation du noyau intercalaire.Among the steps known and not described here in detail, there are the steps of preparation of the upper subsets, the steps of preparation of the lower subsets, and the steps of preparation of the intermediate core.

Le sous-ensemble supérieur 2 comprend au moins une couche de dessus qui assure la protection de la planche de la glisse et la décoration de cette dernière. Le sous-ensemble supérieur contient éventuellement une ou plusieurs couches de renfort. Le sous-ensemble supérieur peut également contenir d'autres éléments tel qu'une interface permettant la fixation des éléments de fixation au ski dans le cas où ces derniers sont fixés à la planche de glisse pendant la fabrication de cette dernière.The upper subassembly 2 comprises at least one top layer which ensures the protection of the slide board and the decoration of the latter. The upper subassembly optionally contains one or more reinforcing layers. The upper subassembly may also contain other elements such as an interface for fixing the fasteners to the ski in the case where they are attached to the gliding board during the manufacture of the latter.

Le sous-ensemble inférieur 3 comprend de façon connue des carres, lesquelles sont la plupart du temps métalliques et une semelle de glisse 14 et un renfort 17.The lower subassembly 3 comprises in a known manner edges, which are mostly metal and a sliding sole 14 and a reinforcement 17.

L'entretoise de finition 18 ainsi que l'insert de rigidification 8 seront décrits plus en détail plus loin.The finishing spacer 18 and the stiffening insert 8 will be described in more detail below.

Après les différentes étapes de préparation des constituants de la planche de glisse, viennent les étapes de réalisation de l'ébauche de planche de glisse 15.After the various stages of preparation of the constituents of the gliding board, come the steps of producing the blank board 15.

Ces étapes commencent par l'étape de mise en place du sous-ensemble supérieur 2, du sous-ensemble inférieur 3 et du noyau 4 dans un moule. Ce moule est chauffé puis mis sous presse et l'on obtient une ébauche de planche de glisse.These steps begin with the step of setting up the upper subset 2, the lower subset 3 and the core 4 in a mold. This mold is heated then put in press and one gets a draft of gliding board.

Comme il est visible à la figure 2, une première ouverture 5 longitudinale est ménagée à l'extrémité arrière du sous-ensemble supérieur 2. Une deuxième ouverture 6 est ménagée à l'extrémité arrière du sous-ensemble inférieur. Une troisième ouverture 7 est également ménagée à l'extrémité arrière du noyau intercalaire.As it is visible to the figure 2 a first longitudinal opening 5 is provided at the rear end of the upper subassembly 2. A second opening 6 is provided at the rear end of the lower subset. A third opening 7 is also provided at the rear end of the intermediate core.

La première, la deuxième et la troisième ouverture sont sensiblement de dimension égale. D'autre part, elles se retrouveront superposées et alignées verticalement lorsque le sous-ensemble supérieur, le sous-ensemble inférieur et le noyau seront eux-mêmes superposés.The first, the second and the third openings are substantially of equal size. On the other hand, they will be superimposed and aligned vertically when the upper subassembly, the lower subset and the core will themselves be superimposed.

Après la mise sous presse du moule et le chauffage de celui-ci, on obtient une ébauche de planche de glisse 15 telle que celle-ci est visible à la figure 3.After pressing the mold and heating it, a roughing board is obtained 15 such that it is visible at the figure 3 .

L'étape suivante consiste en une première phase de finition.The next step is a first finishing phase.

La première phase de finition comprend l'ébavurage latérale de ladite ébauche de planche de glisse. L'ébavurage latérale est une opération courante dans la fabrication de planche de glisse, elle consiste à rogner le superflu de sous-ensemble supérieur qui dépasse des carres lorsque l'ébauche de planche de glisse sort du moule.The first finishing phase includes the lateral deburring of said board blank. Lateral deburring is a common operation in the manufacture of gliding board, it consists in trimming the superfluous upper subassembly that protrudes from the edges when the blank board slides out of the mold.

Dans une variante de réalisation, le sous-ensemble supérieur 2 est mis en place dans le moule sans que la première ouverture n'y soit ménagée. C'est alors lors de cette première phase de finition qu'est découpée la première ouverture 5 dans le sous-ensemble supérieur.In an alternative embodiment, the upper subassembly 2 is placed in the mold without the first opening being provided. It is then during this first finishing phase that the first opening 5 is cut in the upper subassembly.

L'ébauche de planche de glisse 15 comprend dans sa partie arrière une entaille allongée, laquelle est constituée par la superposition de la première ouverture 5, de la troisième ouverture 7 et de la deuxième ouverture 6.The roughing board blank 15 comprises in its rear part an elongated notch, which is constituted by the superposition of the first opening 5, the third opening 7 and the second opening 6.

L'entaille allongée 16 a un contour en « V » prévu pour faciliter l'insertion de l'insert de rigidification et de l'entretoise de finition.The elongated notch 16 has a "V" contour designed to facilitate the insertion of the stiffening insert and the finishing spacer.

L'étape suivante consiste en la mise en place d'une entretoise de finition 18 dans l'entaille allongée. L'entretoise de finition 18 est une pièce rigide dont la forme est rigoureusement complémentaire de celle de l'entaille allongée 16. Sa surface inférieure est affleurante avec la surface de la semelle de glisse, voire légèrement en retrait par rapport à cette dernière.The next step consists of placing a finishing spacer 18 in the elongated slot. The finishing spacer 18 is a rigid piece whose shape is rigorously complementary to that of the elongated notch 16. Its lower surface is flush with the surface of the sliding sole, or slightly recessed relative thereto.

L'étape qui suit la mise en place de l'entretoise de finition 18 dans l'entaille allongée 16 est une deuxième phase de finition. Lors de cette deuxième phase de finition on usine la semelle de glisse ainsi que les carres.The step following the establishment of the finishing spacer 18 in the elongated cut 16 is a second finishing phase. During this second phase of finishing, the gliding sole and the edges are machined.

Une fois l'usinage terminé on retire l'entretoise de finition. L'ébauche de planche glisse est désormais terminée.Once machining is finished, remove the finishing spacer. The board sketch is now complete.

Les deux dernières étapes consistent d'une part, en l'insertion de l'insert de rigidification dans l'entaille allongée et d'autre part, en la fixation de l'insert de rigidification à l'ébauche de planche de glisse.The last two steps consist, on the one hand, in inserting the stiffening insert into the elongated notch and, on the other hand, in attaching the stiffening insert to the board blank.

La méthode de fabrication d'une planche de glisse qui précède concerne une méthode de fabrication dans laquelle le noyau intercalaire est préparé avant sa mise en place dans le moule. Cependant la méthode de fabrication selon l'invention peut tout aussi bien s'appliquer dans le cas où le noyau intercalaire est réalisé dans le moule et non pas avant sa mise en place. Ceci est notamment le cas pour les planches de glisse injectées.The method of manufacturing a gliding board that precedes relates to a method of manufacture in which the intermediate core is prepared before it is placed in the mold. However, the method of manufacture according to the invention can equally well apply in the case where the intermediate core is made in the mold and not before its introduction. This is particularly the case for injected slides.

Pour la fabrication d'une planche de glisse injectée on met dans le moule un sous-ensemble inférieur, un sous-ensemble supérieur. On referme le moule puis on injecte le matériau qui constituera le noyau intercalaire. Par conséquent dans une méthode de fabrication alternative selon l'invention, l'étape de préparation du noyau intercalaire est remplacée par une étape d'injection du matériel du noyau dans le moule.For the manufacture of an injected gliding board is placed in the mold a lower subassembly, an upper subassembly. We close the mold and then inject the material that will form the intermediate core. Consequently, in an alternative manufacturing method according to the invention, the step of preparing the intermediate core is replaced by a step of injecting the material of the core into the mold.

Comme on peut le voir aux figures 4 et 5 l'insert de rigidification est encastré dans l'ébauche 15 de planche de glisse. L'encastrement est garanti par le fait que la première ouverture 5, ménagée dans le sous-ensemble supérieur est de dimensions légèrement inférieures à la deuxième 6 et à la troisième ouvertures 7 respectivement ménagées dans le sous-ensemble inférieur et dans le noyau. Une gorge périphérique 19 est ménagée sur le pourtour de l'insert de rigidification 8. La gorge 19 est dimensionnée de telle façon que le sous-ensemble supérieur peut s'y insérer. A l'avant de l'insert de rigidification 8 une vis 20 maintient celui-ci sur l'ébauche de planche de glisse.As can be seen at Figures 4 and 5 the stiffening insert is embedded in the board blank 15. The embedding is guaranteed by the fact that the first opening 5 formed in the upper subassembly is slightly smaller than the second 6 and the third openings 7 respectively provided in the lower subset and in the core. A peripheral groove 19 is formed on the periphery of the stiffening insert 8. The groove 19 is dimensioned so that the upper subassembly can be inserted therein. At the front of the stiffening insert 8 a screw 20 holds it on the gliding board blank.

La fixation de l'insert de rigidification par une ou plusieurs vis 20 permet à l'utilisateur de démonter l'insert de rigidification et de le remplacer par un autre insert de rigidification. On peut ainsi prévoir différents inserts de rigidification pour différents usages. On peut également prévoir des inserts de rigidification de différentes formes pour différentes pratiques. On peut enfin prévoir des inserts de rigidification en matériaux différents de façon à donner à la planche de glisse des comportements différents en flexion, en torsion, etc.....Fixing the stiffening insert with one or more screws 20 allows the user to dismount the stiffening insert and replace it with another stiffening insert. It is thus possible to provide different stiffening inserts for different uses. It is also possible to provide stiffening inserts of different shapes for different practices. Finally, it is possible to provide stiffening inserts of different materials so as to give the gliding board different behaviors in flexion, torsion, etc. .....

L'insert de rigidification décrit aux figures 4 et 5 comprend une face inférieure concave. Une telle face inférieure concave permet d'améliorer la portance de l'extrémité arrière de la planche de glisse. Une portance améliorée est utile pour une utilisation en neige poudreuse, mais également sur neige tassée, par exemple, pour une utilisation freestyle, lors de la réception de sauts.The stiffening insert described in Figures 4 and 5 comprises a concave lower face. Such a concave underside makes it possible to improve the lift of the rear end of the gliding board. Improved lift is useful for use in powdery snow, but also on packed snow, for example, for freestyle use, when receiving jumps.

La face inférieure concave de l'insert de rigidification 8 est affleurante avec la surface inférieure de la semelle de glisse 14.The concave lower face of the stiffening insert 8 is flush with the lower surface of the sliding sole 14.

Dans une autre variante de réalisation de l'invention, l'insert de rigidification 8 est fixé à l'ébauche de planche de glisse par un moyen non démontable. Ainsi on ne permet pas à l'utilisateur final de modifier le ski en changeant l'insert de rigidification. En revanche il s'agit d'une modularité pour le fabriquant de planche de glisse. En effet celui-ci peut fabriquer des skis différents sur la base d'une même ébauche de planche de glisse.In another variant embodiment of the invention, the stiffening insert 8 is attached to the gliding board blank by non-removable means. Thus the end user is not allowed to modify the ski by changing the stiffening insert. On the other hand, it is a modularity for the gliding board manufacturer. Indeed it can make different skis on the basis of the same draft board gliding.

Dans une autre variante de réalisation de l'invention, l'insert de rigidification est fixé à l'ébauche de planche de glisse par un moyen difficilement démontable. Un moyen difficilement démontable n'est pas prévu pour être démonté par l'utilisateur final. En revanche celui-ci pourra être démonté par un professionnel, par exemple par un détaillant ou un réparateur de planche de glisse. L'objectif recherché par une telle variante est de permettre aux professionnels de démonter l'insert de rigidification pour pouvoir procéder à un réusinage des carres ou de la semelle de glisse.In another variant embodiment of the invention, the stiffening insert is fixed to the gliding board blank by means that are difficult to dismount. A hardly removable means is not intended to be disassembled by the end user. However it can be dismantled by a professional, for example by a retailer or a snowboard repairer. The objective sought by such a variant is to allow professionals to dismantle the stiffening insert to be able to remodel the edges or gliding sole.

Dans la planche de glisse décrite aux figures 1 à 5, le sous-ensemble supérieur et le sous-ensemble inférieur comprennent chacun un renfort en fibre que l'on imprègne de résine avant la mise dans le moule. Au moment de la mise sous presse du moule et de la mise en température de celui-ci, la résine réticule, se durcit. Le trop plein de résine, s'évacue et réalise notamment peau 9 verticale sur la périphérie de l'entaille allongée. Cette peau 9 garantit l'étanchéité de la planche de glisse au niveau de l'entaille.In the gliding board described in Figures 1 to 5 the upper subassembly and the lower subassembly each comprise a fiber reinforcement which is impregnated with resin before being put into the mold. At the time of pressurizing the mold and heating it, the reticulated resin hardens. The overflow of resin, evacuates and realizes in particular skin 9 vertical on the periphery of the elongated notch. This skin 9 guarantees the waterproofness of the gliding board at the notch.

La figure 6 décrit une vue en perspective d'un deuxième mode de réalisation de l'invention.The figure 6 discloses a perspective view of a second embodiment of the invention.

La planche de glisse qui y est décrite comprend comme dans le mode de réalisation précédent une ébauche de planche de glisse 15 et un insert de rigidification 8. L'insert de rigidification 8 comprend une portion antérieure 11 insérée dans une entaille allongée dans l'ébauche de planche de glisse, et une portion postérieure 12 qui fait saillie depuis l'ébauche de planche de glisse et réalise l'extrémité arrière de la planche de glisse. Une fente 22 est ménagée dans la portion postérieure 12 de l'insert de rigidification 8. Cette fente a pour effet d'alléger la planche de glisse et de rappeler la forme en queue d'hirondelle de l'ébauche de planche de glisse. Cette fente à également pour fonction de permettre la fixation de peau de phoque pour la pratique du ski de randonnée.The gliding board described therein comprises, as in the previous embodiment, a gliding board blank 15 and a stiffening insert 8. The stiffening insert 8 comprises an anterior portion 11 inserted into an elongated notch in the blank gliding board, and a rear portion 12 which protrudes from the blank board glide and realizes the rear end of the gliding board. A slot 22 is formed in the rear portion 12 of the stiffening insert 8. This slot has the effect of lightening the gliding board and to remind the swallow tail shape of the gliding board blank. This slot also serves to allow the attachment of seal skin for the practice of ski touring.

Les figures 7 et 8 montrent respectivement une vue en coupe partielle longitudinale de la planche de glisse décrite à la figure 6 et une coupe transversale de la planche de glisse. L'insert de rigidification 8 se différencie de l'insert décrit dans le premier mode de réalisation par le fait que sa face inférieure 21 est bombée.The Figures 7 and 8 respectively show a partial longitudinal sectional view of the gliding board described in FIG. figure 6 and a cross section of the gliding board. The stiffening insert 8 differs from the insert described in the first embodiment in that its lower face 21 is curved.

Lorsqu'elle est utilisée dans la neige poudreuse, une planche de glisse équipée d'un insert de rigidification ayant une face inférieure bombée ou convexe, assurera à l'utilisateur un meilleur contrôle. La partie bombée de l'insert fait office de dérive à l'extrémité arrière de la planche de glisse. Lorsqu'il est utilisé sur piste, une telle planche de glisse assurera à l'utilisateur un meilleur contrôle du slide, c'est-à-dire du dérapage.When used in powder snow, a gliding board equipped with a stiffening insert having a domed or convex underside, will provide the user with better control. The domed portion of the insert serves as a drift at the rear end of the gliding board. When used on the track, such a gliding board will ensure the user better control of the slide, that is to say skidding.

La figure 9 montre une vue en coupe transversale d'une planche glisse 1 équipée d'un insert de rigidification 8 selon un troisième mode de réalisation de l'invention. Cet insert est partiellement semblable aux inserts décrits plus haut, c'est pourquoi, il ne sera pas fait ici de description détaillée de ce dernier. Il convient de préciser en revanche que l'insert de rigidification 8 présente une face inférieure plane. D'autre part, lorsque l'insert de rigidification 8 est inséré dans l'entaille allongée de l'ébauche de planche de glisse 1, la face inférieure de l'insert se trouve dans le même plan que la surface inférieure de la semelle de glisse. Par conséquent, il n'est plus nécessaire de retirer l'insert de rigidification de l'entaille pour pouvoir réusiner la surface de glisse de la planche de glisse.The figure 9 shows a cross-sectional view of a sliding board 1 equipped with a stiffening insert 8 according to a third embodiment of the invention. This insert is partially similar to the inserts described above, so it will not be here detailed description of the latter. It should be noted however that the stiffening insert 8 has a flat bottom face. On the other hand, when the stiffening insert 8 is inserted into the elongated notch of the gliding board blank 1, the lower face of the insert is in the same plane as the lower surface of the soleplate. slips. Therefore, it is no longer necessary to remove the stiffening insert of the notch to be able to remanufacture the gliding surface of the gliding board.

D'autre part, la fabrication d'une planche de glisse selon le troisième mode de réalisation de l'invention se révèle un peu plus simple car il n'est pas nécessaire de prévoir une entretoise de finition.On the other hand, the manufacture of a gliding board according to the third embodiment of the invention is a little simpler because it is not necessary to provide a finishing spacer.

La méthode de fabrication d'une planche de glisse 1 selon le troisième mode de réalisation de l'invention comportant les étapes suivantes :

  • Préparation d'un sous ensemble supérieur 2 comprenant une couche de dessus.
  • Préparation d'un sous-ensemble inférieur 3 comprenant une semelle de glisse 14 et des carres 13, ledit sous-ensemble inférieur 3 comportant une deuxième ouverture 6 longitudinale.
  • Préparation d'un noyau 4 présentant une troisième ouverture 7 longitudinale.
  • Préparation d'un élément de rigidification 8.
  • Mise en place dudit sous ensemble supérieur 2, dudit sous-ensemble inférieur 3 et dudit noyau 4 dans un moule de façon à obtenir une ébauche de planche de glisse 15.
  • Première phase de finition.
  • Mise en place de l'élément de rigidification 8 dans lesdites deuxième 6 et troisième 7 ouvertures longitudinales.
  • Fixation dudit élément de rigidification 8 à la planche de glisse 1.
  • Deuxième phase de finition.
The method of manufacturing a gliding board 1 according to the third embodiment of the invention comprising the following steps:
  • Preparation of an upper subassembly 2 comprising a top layer.
  • Preparation of a lower subassembly 3 comprising a sliding sole 14 and edges 13, said lower subassembly 3 having a second longitudinal opening 6.
  • Preparation of a core 4 having a third longitudinal opening 7.
  • Preparation of a stiffening element 8.
  • Placing said upper subassembly 2, said lower subset 3 and said core 4 in a mold so as to obtain a gliding board blank 15.
  • First phase of finishing.
  • Placing the stiffening element 8 in said second 6 and third 7 longitudinal openings.
  • Attaching said stiffening element 8 to the gliding board 1.
  • Second phase of finishing.

Dans le cas où le sous-ensemble supérieur n'est pas découpé avant d'être mis dans le moule, la première phase de finition comprend le découpage d'une première ouverture 5 longitudinale dans ledit sous ensemble supérieur 2. Dans l'autre cas, c'est l'étape de préparation du sous-ensemble supérieur 2 qui comprend le découpage d'une première ouverture 5 longitudinale.In the case where the upper subassembly is not cut before being put in the mold, the first finishing phase comprises the cutting of a first longitudinal opening in said upper subassembly 2. In the other case this is the step of preparing the upper subassembly 2 which comprises cutting a first longitudinal opening.

Etant donné que la face inférieure de l'insert de rigidification est plane, la deuxième phase de finition qui comprend l'usinage de ladite semelle de glisse 14 et des carres 13 peut être réalisée après l'insertion de l'insert de rigidification.Since the lower face of the stiffening insert is flat, the second finishing phase which comprises the machining of said sliding sole 14 and edges 13 can be performed after the insertion of the stiffening insert.

Comme pour les autres modes de réalisation de l'invention, on peut aussi bien fabriquer la planche de glisse selon l'invention en utilisant la technologie de l'injection. Dans ce cas la méthode de fabrication comprend les étapes suivantes :

  • Préparation d'un sous ensemble supérieur 2 comprenant une couche de dessus, ledit sous-ensemble supérieur comportant éventuellement une première ouverture longitudinale.
  • Préparation d'un sous-ensemble inférieur 3 comprenant une semelle de glisse 14 et des carres 13, ledit sous-ensemble inférieur 3 comportant une deuxième ouverture 6 longitudinale.
  • Préparation d'un élément de rigidification 8.
  • Mise en place dudit sous ensemble supérieur 2, dudit sous-ensemble inférieur 3 dans un moule.
  • Injection du matériau destiné à constituer le noyau 4 de façon à obtenir une ébauche de planche de glisse 15.
  • Mise en place de l'élément de rigidification 8 dans lesdites première 5, deuxième 6 et troisième 7 ouvertures longitudinales.
  • Fixation dudit élément de rigidification 8 à la planche de glisse 1.
As for the other embodiments of the invention, it is also possible to manufacture the gliding board according to the invention by using injection technology. In this case, the manufacturing method comprises the following steps:
  • Preparation of an upper subassembly 2 comprising a top layer, said upper subassembly possibly comprising a first longitudinal opening.
  • Preparation of a lower subassembly 3 comprising a sliding sole 14 and edges 13, said lower subassembly 3 having a second longitudinal opening 6.
  • Preparation of a stiffening element 8.
  • Placing said upper subassembly 2, said lower subset 3 in a mold.
  • Injecting the material intended to constitute the core 4 so as to obtain a gliding board blank 15.
  • Placing the stiffening element 8 in said first 5, second 6 and third 7 longitudinal openings.
  • Attaching said stiffening element 8 to the gliding board 1.

L'invention ne se limite pas aux quelques modes de réalisation décrits ici à titre d'exemple et elle concerne toute réalisation équivalente.The invention is not limited to the few embodiments described here by way of example and it relates to any equivalent embodiment.
