Description

La présente invention concerne une planche de glisse, un dispositif de fixation de chaussure sur une planche de glisse et un équipement de snowboard comprenant ladite planche et ledit dispositif de fixation.The present invention relates to a gliding board, a shoe attachment device on a gliding board and snowboard equipment comprising said board and said attachment device.

Plus précisément, l'invention concerne une planche de glisse équipée, notamment, d'un rail d'ancrage destiné à assurer la liaison et le blocage d'une embase spécifique de réception et de fixation d'une chaussure.More specifically, the invention relates to a gliding board equipped, in particular, an anchor rail for ensuring the connection and locking of a specific base for receiving and fixing a shoe.

L'invention se rattache au domaine des sports de glisse, sur neige ou aquatique, et se rapporte plus particulièrement à des perfectionnements tant de la planche que du dispositif de fixation assurant la liaison entre l'embase de réception de la chaussure et la planche.The invention relates to the field of snow sports, snow or water, and relates more particularly to improvements of both the board and the fastener providing the connection between the receiving base of the shoe and the board.

De façon générale et traditionnelle, les planches de glisse ou de surf comprennent un noyau généralement en bois ou en polyuréthane pourvu d'au moins une couche supérieure et une couche inférieure de renfort. Ces planches peuvent être munies d'au moins une réglette ou un rail assurant l'ancrage et l'immobilisation des embases de réception des chaussures pour permettre le réglage de la position longitudinale de chacune des embases sur la planche de glisse.Generally and traditionally, gliding or surfing boards comprise a core generally made of wood or polyurethane provided with at least one upper layer and one lower reinforcing layer. These boards may be provided with at least one strip or a rail ensuring the anchoring and immobilization of the shoe receiving bases to allow the adjustment of the longitudinal position of each of the bases on the gliding board.

Chaque embase est destinée à être montée de manière réglable et amovible sur la face supérieure de la planche et est pourvue d'au moins un élément de verrouillage sur la planche.Each base is intended to be mounted in an adjustable and removable manner on the upper face of the board and is provided with at least one locking element on the board.

Chaque embase délimite un logement dans lequel une chaussure est immobilisée par des moyens de maintien et comporte un disque central de verrouillage coopérant, d'une part, avec le rail d'ancrage porté par la planche et supportant, d'autre part, des éléments de blocage en rotation, destinés à bloquer la rotation de l'embase par rapport au disque central et par conséquence la rotation de l'embase par rapport à la planche.Each base delimits a housing in which a shoe is immobilized by holding means and comprises a central locking disc cooperating, on the one hand, with the anchor rail carried by the board and supporting, on the other hand, elements rotational locking, intended to block the rotation of the base by relative to the central disk and consequently the rotation of the base relative to the board.

Il est essentiel pour le surfeur d'ajuster l'écartement entre ses pieds et donc de régler la position longitudinale des embases sur la planche avant l'utilisation de la planche sur neige ou sur l'eau, ceci par déplacement en translation de l'ensemble embase-disque central par rapport au rail d'ancrage.It is essential for the surfer to adjust the spacing between his feet and thus to adjust the longitudinal position of the bases on the board before the use of the board on snow or on the water, this by displacement in translation of the central disk-drive assembly relative to the anchor rail.

Une fois le réglage longitudinal et le verrouillage des embases effectués, il est alors indispensable, pour des raisons de sécurité, de pouvoir garantir le blocage en translation de ces embases c'est-à-dire assurer qu'il n'y aura pas de modifications intempestives du réglage.Once the longitudinal adjustment and the locking of the bases made, it is then essential, for security reasons, to be able to guarantee the locking in translation of these bases that is to say ensure that there will be no untimely changes to the setting.

Dans la demande FR 12 52863 , le dispositif de fixation est réglable et comporte un pivot vertical relié au disque central de verrouillage par une tige filetée axiale.In the request FR 12 52863 , the fixing device is adjustable and comprises a vertical pivot connected to the central locking disk by an axial threaded rod.

Ce pivot autorise, de façon temporaire, la rotation de l'embase pour assurer le réglage, d'une part, de la position angulaire des chaussures relativement à l'axe longitudinal de la planche et, d'autre part, de sa position longitudinale sur la planche et, de ce fait, de l'écartement des pieds du surfeur sur ladite planche par réglage de la position longitudinale des deux embases sur la planche, l'une par rapport à l'autre.This pivot allows, temporarily, the rotation of the base for adjusting, on the one hand, the angular position of the shoes relative to the longitudinal axis of the board and, on the other hand, its longitudinal position on the board and, therefore, the spacing of the feet of the surfer on said board by adjusting the longitudinal position of the two bases on the board, relative to each other.

Dans la demande FR 13 57369 , le pivot est muni, à sa partie inférieure, d'une came rotative coopérant directement avec une réglette d'ancrage.In the request FR 13 57369 , the pivot is provided at its lower part with a rotary cam cooperating directly with an anchor strip.

Le DE 196 33 536 et le US 6 189 899 décrivent des planches de surf comprenant un rail d'ancrage sous forme d'un profilé métallique monté sur la planche en délimitant intérieurement une gorge de réception d'un élément de verrouillage de l'embase qui est obturée partiellement, sur son bord supérieur et de part et d'autre, par des épaulements longitudinaux de retenue.The DE 196 33 536 and the US 6,189,899 disclose surfboards comprising an anchor rail in the form of a metal profile mounted on the board by internally defining a groove for receiving a locking element of the base which is partially closed, on its upper edge and on both sides, by longitudinal retaining shoulders.

Ces épaulements portent, sur leur bord intérieur ou sur leur face supérieure, une série de crans coopérant avec des rangées de dents portées par la face inférieure du disque central de verrouillage de l'embase de fixation pour assurer son blocage en translation, lorsque le réglage de la position sur la planche a été effectué.These shoulders bear, on their inner edge or on their upper face, a series of notches cooperating with rows of teeth carried by the lower face of the central locking disk of the fixing base to ensure its locking in translation, when the adjustment the position on the board was done.

Les deux rangées de dents s'étendent sous le disque selon deux lignes parallèles et sensiblement diamétrales et à proximité du centre du disque pour se positionner en regard et en contact avec les crans du rail d'ancrage.The two rows of teeth extend under the disk along two parallel and substantially diametrical lines and near the center of the disk to position themselves facing and in contact with the notches of the anchoring rail.

Du fait de la réalisation des dents directement sur le rail, cette disposition qui fragilise les épaulements, présente des risques d'échappement de l'élément d'ancrage susceptibles d'entraîner une rupture de la liaison entre l'embase et la planche ce qui n'est pas acceptable pour la sécurité du surfeur.Due to the realization of the teeth directly on the rail, this arrangement which weakens the shoulders, presents risks of escape of the anchoring element may cause a break in the connection between the base and the board which is not acceptable for the safety of the surfer.

En outre, les dimensions des dents sont nécessairement limitées car la largeur du rail doit être suffisamment étroite pour emprisonner efficacement l'élément d'ancrage et ce compromis est préjudiciable à l'efficacité de la retenue en translation de l'embase.In addition, the dimensions of the teeth are necessarily limited because the width of the rail must be narrow enough to effectively trap the anchor element and this compromise is detrimental to the effectiveness of the retention in translation of the base.

Au surplus, l'étroitesse du rail et le faible écartement concomitant des rangées de dents sur le disque laissent subsister un léger jeu en rotation et une instabilité de l'embase sur la planche de part et d'autre du disque central.In addition, the narrowness of the rail and the small spacing concomitant rows of teeth on the disc leave a slight play in rotation and instability of the base on the board on either side of the central disc.

La présente invention a pour but de résoudre ces problèmes techniques de manière satisfaisante et efficace en proposant, grâce à un agencement simple, une planche dont la face supérieure est parfaitement plane et un dispositif de fixation perfectionné dans lequel la fonction d'ancrage et la fonction de blocage en translation de l'embase sont assurées de façon séparée et optimisée ainsi qu'un équipement complet de surf comprenant ladite planche équipée du dispositif perfectionné.The present invention aims to solve these technical problems satisfactorily and effectively by proposing, thanks to a simple arrangement, a board whose upper face is perfectly flat and a an improved fixing device in which the anchoring function and the locking function in translation of the base are provided separately and optimized and a complete surfing equipment comprising said board equipped with the improved device.

Ce but est atteint, selon l'invention, au moyen d'une planche de glisse dont la structure comprend au moins une couche inférieure, au moins une couche supérieure, un noyau, au moins un rail délimitant une gorge à ouverture supérieure pour la réception et le guidage d'un élément d'ancrage d'une embase de fixation de chaussure, caractérisée en ce qu'elle comprend au moins une barrette crantée indépendante et distante de la gorge du rail et destinée à coopérer avec au moins un secteur denté périphérique porté par la face inférieure de l'embase en vue d'assurer son blocage en translation longitudinale.This object is achieved, according to the invention, by means of a gliding board whose structure comprises at least one lower layer, at least one upper layer, one core, at least one rail delimiting an upper opening groove for receiving and guiding an anchoring element of a shoe attachment base, characterized in that it comprises at least one notched bar independent and remote from the groove of the rail and intended to cooperate with at least one peripheral tooth sector carried by the lower face of the base to ensure its locking in longitudinal translation.

Selon une caractéristique avantageuse, la distance séparant l'axe du rail du bord de la barrette est comprise entre 20mm et 40mm.According to an advantageous characteristic, the distance separating the axis of the rail from the edge of the bar is between 20mm and 40mm.

Selon une autre caractéristique, le rail et la barrette crantée sont intégrés dans des cavités ménagées dans l'épaisseur de la planche.According to another characteristic, the rail and the toothed bar are integrated in cavities formed in the thickness of the board.

De préférence, l'ouverture supérieure de la gorge et la barrette crantée affleurent la face supérieure de la planche.Preferably, the upper opening of the groove and the toothed bar are flush with the upper face of the board.

Selon une variante spécifique, la planche comporte deux barrettes crantées situées à équi-distance dudit rail.According to a specific variant, the board comprises two notched bars located equi-distance from said rail.

Selon une autre caractéristique, chaque barrette crantée est intégrée dans la structure de la planche au travers des couches supérieures de protection et de renfort et dans un insert étanche positionné dans une cavité du noyau.According to another characteristic, each toothed bar is integrated into the structure of the board at through upper layers of protection and reinforcement and in a sealed insert positioned in a cavity of the core.

De préférence, une couche supérieure de renfort et d'étanchéité se prolonge sous la surface inférieure de ladite barrette.Preferably, an upper layer of reinforcement and sealing extends under the lower surface of said bar.

Selon une autre variante avantageuse, les crans de ladite barrette sont orientés transversalement et s'étendent sur toute sa largeur.According to another advantageous variant, the notches of said bar are oriented transversely and extend over its entire width.

Selon encore une autre variante, le rail porte des ailettes d'accrochage scellées dans l'épaisseur de la planche au contact du noyau.According to yet another variant, the rail carries fastening vanes sealed in the thickness of the board in contact with the core.

Un autre objet de l'invention est un dispositif de fixation pour une planche de glisse tel que définie ci-dessus, comprenant une embase de réception d'une chaussure pourvue d'une ouverture centrale recevant un disque de verrouillage actionné par un pivot coopérant avec des éléments de blocage en rotation de l'embase, caractérisé en ce que la face inférieure du disque porte au moins un secteur denté périphérique destiné à coopérer avec la barrette crantée de la planche pour assurer le blocage en translation longitudinale de l'embase sur ladite planche.Another object of the invention is a fixing device for a gliding board as defined above, comprising a base for receiving a shoe provided with a central opening receiving a locking disk actuated by a pivot cooperating with blocking elements in rotation of the base, characterized in that the underside of the disk carries at least one peripheral toothed sector intended to cooperate with the notched bar of the board to ensure the locking in longitudinal translation of the base on said board.

Selon une caractéristique avantageuse, le secteur denté est distinct des éléments de blocage en rotation du disque.According to an advantageous characteristic, the toothed sector is distinct from the locking elements in rotation of the disk.

Selon une première variante du dispositif de fixation, les éléments de blocage en rotation du disque sont constitués d'une couronne crénelée à l'intérieur de laquelle s'étend ledit secteur denté.According to a first variant of the fixing device, the rotational locking elements of the disc consist of a crenellated ring within which said toothed sector extends.

Selon une autre variante, la couronne crénelée délimite le bord extérieur du secteur denté périphérique dont le bord intérieur est rectiligne.According to another variant, the crenellated crown defines the outer edge of the peripheral tooth sector whose inner edge is rectilinear.

Selon encore une variante spécifique, le secteur denté périphérique comporte au moins un bord extérieur qui s'étend sur une zone angulaire du pourtour inférieur du disque.According to another specific variant, the peripheral tooth sector comprises at least one outer edge which extends over an angular zone of the lower periphery of the disk.

Selon encore une autre variante les secteurs dentés sont réalisés sous forme de bandes parallèles ortho-radiales.According to yet another variant the toothed sectors are made in the form of ortho-radial parallel strips.

Selon un autre mode de réalisation du dispositif, le disque de verrouillage comprend un élément inférieur indépendant rapporté et monté de façon coaxiale sous l'embase et dont le pourtour inférieur porte ledit secteur denté.According to another embodiment of the device, the locking disc comprises an independent lower element attached and mounted coaxially under the base and whose lower periphery carries said toothed sector.

De préférence, le dispositif de l'invention comprend deux secteurs dentés périphériques diamétralement opposés sur le pourtour inférieur du disque et coopérant chacun avec l'une des barrettes.Preferably, the device of the invention comprises two diametrically opposed peripheral tooth sectors on the lower periphery of the disc and each cooperating with one of the bars.

Selon une caractéristique du dispositif, la largeur d'un secteur denté est inférieure ou égale à celle d'une barrette crantée.According to a feature of the device, the width of a toothed sector is less than or equal to that of a notched bar.

De préférence, les secteurs dentés sont ménagés deux à deux sur des zones angulaires diamétralement opposées du pourtour du disque.Preferably, the toothed sectors are arranged in pairs on diametrically opposite angular regions of the periphery of the disk.

De même, la hauteur des dents dudit secteur denté est inférieure ou égale à la profondeur des crans de ladite barrette.Similarly, the height of the teeth of said toothed sector is less than or equal to the depth of the notches of said bar.

De préférence, le profil des dents du disque est sensiblement identique à celui des crans de ladite barrette.Preferably, the profile of the disc teeth is substantially identical to that of the notches of said bar.

Encore un autre objet de l'invention est un équipement de snowboard comprenant une planche de glisse et un dispositif de fixation de chaussure tels que définis ci-dessus.Yet another object of the invention is a snowboard equipment comprising a gliding board and a shoe attachment device as defined above.

Le dispositif de fixation, tel que perfectionné par l'invention, est intégré à la fois à la planche de façon totalement affleurante et à l'embase de façon compacte, ce qui permet d'offrir aux surfeurs un blocage efficace en translation et une grande stabilité des pieds sur une planche dont la face supérieure est parfaitement plane et lisse et sans modification du poids ni du volume de l'embase.The fixing device, as perfected by the invention, is integrated both to the board in a fully flush manner and to the base compactly, which allows to offer surfers an effective blocking in translation and a great stability of the feet on a board whose upper face is perfectly flat and smooth and without changing the weight or the volume of the base.

Les risques de butée, d'accrochage et/ou de choc contre une partie en saillie sont ainsi écartés ce qui évite les risques d'arrachement et de détérioration de la planche.The risks of abutment, attachment and / or impact against a projecting part are thus avoided which avoids the risk of tearing and deterioration of the board.

En outre, les moyens de blocage en translation ne modifient ni ne perturbent d'aucune façon le mode d'ancrage de l'embase dans la planche.In addition, the translation locking means do not modify or in any way disturb the anchoring mode of the base in the board.

Ainsi, le dispositif de l'invention reste compatible avec deux modes possibles d'ancrage (standard 4x4 avec couronne centrale vissée ou came centrale) et peut donc recevoir deux types d'embase de fixation de chaussure.Thus, the device of the invention remains compatible with two possible modes of anchoring (4x4 standard with screwed center ring or central cam) and can therefore receive two types of shoe attachment base.

Cette configuration rend la planche équipée du dispositif de l'invention particulièrement esthétique et facile à stocker ou à transporter puisque sa face supérieure ne présente pas d'aspérité.This configuration makes the board equipped with the device of the invention particularly aesthetic and easy to store or transport since its upper face has no roughness.

En outre, l'utilisation de la planche de l'invention ne requiert que des adaptations mineures des embases puisque seul le disque de verrouillage doit être remplacé ou complété par une pièce rapportée.In addition, the use of the board of the invention requires only minor adaptations of the bases since only the locking disk must be replaced or supplemented by an insert.

Le dispositif de fixation de l'invention, tel que représenté sur les figures, est destiné à équiper des planches de glisse telles qu'un surf des neiges S (figure 1) en vue d'assurer l'ancrage et l'immobilisation réversible d'embases E de réception des chaussures dont un mode de réalisation est illustré par la figure 2A.The fixing device of the invention, as shown in the figures, is intended to equip boards for gliding such as a snowboard S ( figure 1 ) in order to ensure the anchoring and the reversible immobilization of shoe receiving bases E, an embodiment of which is illustrated by the Figure 2A .

Chacune de ces embases délimite un logement ouvert dans lequel une chaussure ou une botte (non représentée) est destinée à être immobilisée par des moyens de maintien, non représentés qui peuvent être par exemple des sangles de maintien.Each of these bases defines an open housing in which a shoe or boot (not shown) is intended to be immobilized by holding means, not shown which may be for example retaining straps.

Un tel dispositif de fixation comprend généralement ; d'une part, un premier jeu de pièces assemblées les unes aux autres sur et autour d'une embase E, (certaines pouvant être démontables et remplaçables en cas d'usure) et, d'autre part, un second jeu de pièces intégrées dans la planche S.
Pour des raisons de clarté, seules les pièces qui concernent directement l'invention seront décrites plus en détail par la suite.Such a fastening device generally comprises; on the one hand, a first set of parts assembled to each other on and around a base E, (some of which may be removable and replaceable in case of wear) and, secondly, a second set of integrated parts in the plate S.
For the sake of clarity, only the parts that directly relate to the invention will be described in more detail later.

Le premier jeu de pièces, illustré par les figures 2A et 3A, est monté sur l'embase E et lui donne des possibilités de réglage en position angulaire.The first set of pieces, illustrated by the Figures 2A and 3A , is mounted on the base E and gives it possibilities of adjustment in angular position.

Ce jeu de pièces comprend essentiellement un pivot axial actionnant un disque de verrouillage 4 (associé parfois à une ou plusieurs entretoises) et un élément d'ancrage T qui se présente, dans le mode de réalisation représenté ici (notamment, par les figure 2B, 2C et 3B), sous la forme d'un pion (en forme de T inversé) pivotant et escamotable porté par la partie inférieure du disque central 4 pour solidariser l'embase E à la planche S. Une fois engagé dans le rail, ce pion peut pivoter de 90 degrés pour mettre l'embase et le disque dans une position de retenue verticale.This set of parts essentially comprises an axial pivot actuating a locking disc 4 (sometimes associated with one or more spacers) and an anchoring element T which is present in the embodiment shown here (in particular by the Figure 2B, 2C and 3B ), in the form of a pivoting pin (T-shaped inverted) and retractable carried by the lower portion of the central disk 4 to secure the base E to the board S. Once engaged in the rail, the pin can rotate 90 degrees to put the base and the disc in a vertical restraint position.

Dans le mode de réalisation des figures 2A et 2B, le disque central de verrouillage 4 coopère par vissage avec l'élément d'ancrage T pour permettre sa rotation de 90 degrés. Le disque 4 comporte des éléments de blocage en rotation sous forme de bagues ou de couronnes crénelées 4a réalisées sous sa surface inférieure et destinées à coopérer avec une deuxième couronne crantée 4b réalisée en regard sur l'embase E. Le vissage complet de la bague supérieure rotative du disque 4 permet alors de serrer les deux couronnes l'une contre l'autre pour bloquer en rotation l'embase E par rapport au disque central 4.In the embodiment of Figures 2A and 2B , the central locking disc 4 cooperates by screwing with the anchoring element T to allow its rotation of 90 degrees. The disc 4 comprises rotational locking elements in the form of rings or crenated rings 4a formed under its lower surface and intended to cooperate with a second toothed ring 4b made opposite the base E. The complete screwing of the upper ring rotary disk 4 then allows to clamp the two rings against each other to block the rotation of the base E relative to the central disk 4.

Par ailleurs, la planche de glisse S comprend un profilé rigide 1 (de préférence en aluminium) destiné à assurer la liaison avec l'embase E via l'élément d'ancrage T, en vue de permettre la fixation des chaussures.Furthermore, the gliding board S comprises a rigid section 1 (preferably made of aluminum) intended to ensure connection with the base E via the anchoring element T, in order to allow the fixing of the shoes.

En effet, l'élément d'ancrage T est positionné dans le profilé ou rail 1 puis tourné d'un quart de tour pour assurer la retenue verticale du disque 4 et de l'embase E par rapport à la planche S.Indeed, the anchoring element T is positioned in the profile or rail 1 then rotated a quarter turn to ensure the vertical retention of the disk 4 and the base E relative to the board S.

Ainsi, les ailettes T1 et T2 (figure 2C) formées par la barre du T sont alors positionnées sous les épaulements 11 du rail d'ancrage 1 pour assurer la retenue verticale du disque 4 par rapport à la planche S.Thus, the fins T1 and T2 ( Figure 2C ) formed by the T bar are then positioned under the shoulders 11 of the anchor rail 1 to ensure the vertical retention of the disc 4 relative to the board S.

Ce profilé est destiné à être logé intégralement dans la structure de la planche, comme illustré par les figures 1 et 2A et comme représenté en coupe de détail sur la figure 4.This profile is intended to be housed integrally in the structure of the board, as illustrated by the Figures 1 and 2A and as shown in detail section on the figure 4 .

A cet effet, le profilé 1 forme un rail délimitant une gorge 10 ouverte sur le dessus. Cette gorge s'étend dans la direction longitudinale de la planche et assure la réception et le guidage de l'élément d'ancrage T porté par l'embase E. En effet, l'élément d'ancrage T peut être déplacé en translation le long du rail 1 avant d'être bloqué dans la position longitudinale choisie à l'aide du pivot axial permettant le verrouillage complet du disque 4 sur l'embase E.For this purpose, the profile 1 forms a rail delimiting a groove 10 open on the top. This groove extends in the longitudinal direction of the board and ensures the reception and guidance of the anchoring element T carried by the base E. In fact, the anchoring element T can be moved in translation on the along the rail 1 before being locked in the longitudinal position chosen with the help of axial pivot allowing complete locking of the disc 4 on the base E.

La gorge 10 est fermée partiellement, sur son bord supérieur et de part et d'autre, par des épaulements longitudinaux 11 rectilignes. Les épaulements 11 participent à la retenue de l'élément d'ancrage T de l'embase E dans le rail 1.The groove 10 is partially closed on its upper edge and on either side by longitudinal shoulders 11 rectilinear. The shoulders 11 participate in the retention of the anchoring element T of the base E in the rail 1.

La coopération entre la gorge 10 et l'élément d'ancrage T permet ainsi, de manière connue en soi, de solidariser les pieds du surfeur avec la planche dans des positions longitudinales susceptibles d'être ajustées préalablement au verrouillage de l'embase E, l'écartement entre les pieds étant un paramètre important à régler par le surfeur.The cooperation between the groove 10 and the anchoring element T thus allows, in a manner known per se, to secure the feet of the surfer with the board in longitudinal positions that can be adjusted prior to the locking of the base E, the distance between the feet being an important parameter to be regulated by the surfer.

Par ailleurs, il est également possible pour le surfeur de choisir la position angulaire de chacune des embases E par rapport à la planche S par déverrouillage du pivot de blocage central qui permet de libérer les couronnes crantées positionnées sur le disque 4 et sur le pourtour de l'ouverture de l'embase E. Aussi, le verrouillage total du pivot central permet à la fois le verrouillage en rotation de l'embase E par rapport au disque 4 et à la planche S et le verrouillage en translation de l'embase E sur la planche S.Moreover, it is also possible for the surfer to choose the angular position of each of the bases E relative to the board S by unlocking the central locking pivot which allows to release the notched crowns positioned on the disc 4 and on the periphery of the opening of the base E. Also, the total locking of the central pivot allows both the locking in rotation of the base E relative to the disc 4 and the board S and the locking in translation of the base E on the board S.

Mais ce verrouillage en translation entre l'élément d'ancrage T et le rail d'ancrage 1, qui interagissent par frottement, peut ne pas être suffisant pour conserver de façon stable et durable la position en translation choisie, d'où la nécessité d'ajouter le dispositif de fixation selon l'invention. En effet, lors de l'évolution sur la neige les efforts appliqués par l'utilisateur sur les embases de retenue de ses pieds sont très importants et ont tendance à modifier le réglage longitudinal initial choisi pour chacune des embases, ce qui n'est pas acceptable. D'où la nécessité d'un système de blocage en translation longitudinale supplémentaire.But this locking in translation between the anchoring element T and the anchoring rail 1, which interact by friction, may not be sufficient to maintain in a stable and durable manner the selected translational position, hence the need to add the fixing device according to the invention. Indeed, during the evolution on the snow the forces applied by the user on the bases of restraint of his feet are very important and tend to change the initial longitudinal adjustment chosen for each of the bases, this which is not acceptable. Hence the need for an additional longitudinal translation locking system.

Bien que le dispositif de fixation de l'invention aille généralement par paire, chaque dispositif étant associé à une seule embase E (figures 1,2A,3A), il serait toutefois possible de prévoir, selon une variante non représentée, que ce dispositif soit adapté (par exemple, en modifiant sa géométrie mais sans changer nécessairement sa structure) pour recevoir à lui-seul deux embases.Although the fixing device of the invention generally goes in pairs, each device being associated with a single base E ( Figures 1.2A , 3A ), it would however be possible to provide, according to a variant not shown, that this device is adapted (for example, by changing its geometry but without necessarily changing its structure) to receive alone two bases.

Par exemple, la planche S pourrait être équipée d'un rail unique suffisamment long pour permettre le montage des deux embases et quatre barrettes crantées seraient alors positionnées en vis-à-vis deux à deux, de part et d'autre de ce rail unique.For example, the board S could be equipped with a single rail long enough to allow the mounting of the two bases and four notched bars would then be positioned vis-à-vis two by two, on either side of this single rail .

Dans un mode de réalisation préférentiel, la planche S présente deux rails dont l'ouverture de la gorge 10 de chaque rail 1 présente généralement une longueur comprise entre 90 mm et 180 mm et, de préférence ente 110 mm et 130 mm pour éviter de raidir la planche en flexion. Chacun des rails 1 est alors destiné à recevoir une seule embase E. La largeur de l'ouverture de la gorge 10 du rail est comprise, quant à elle, entre 15 mm et 25 mm pour assurer une bonne tenue de l'embase E.In a preferred embodiment, the board S has two rails, the opening of the groove 10 of each rail 1 generally has a length of between 90 mm and 180 mm and preferably between 110 mm and 130 mm to avoid stiffening. the board in flexion. Each of the rails 1 is then intended to receive a single base E. The width of the opening of the groove 10 of the rail is, meanwhile, between 15 mm and 25 mm to ensure a good hold of the base E.

Comme illustré par la figure 4, le profilé 1 formant rail est destiné à être logé intégralement dans l'épaisseur de la planche de telle sorte que l'ouverture de la gorge 10 s'étende de façon sensiblement affleurante à la face supérieure qui reste ainsi parfaitement plane. Plus précisément, l'ouverture de la gorge peut se trouver soit au niveau de la face supérieure de la planche, soit à quelques millimètres en-dessous dans le cas où les épaulements 11 sont recouverts, partiellement ou totalement, par la couche supérieure de protection F et/ou par une couche de renfort R2 (ces différentes couches seront décrites par la suite en référence aux figures 4, 5A et 5B).As illustrated by figure 4 , the profile 1 forming a rail is intended to be housed integrally in the thickness of the board so that the opening of the groove 10 extends substantially flush with the upper face which remains perfectly flat. More specifically, the opening of the groove may be either at the upper face of the board, or a few millimeters below in the case where the shoulders 11 are covered, partially or completely, by the upper layer of protection F and / or by a reinforcing layer R2 (these different layers will be described later with reference to Figures 4, 5A and 5B ).

Dans le mode de réalisation représenté, le profilé 1 porte des ailettes 12 d'accrochage s'étendant dans la direction transversale de la planche S et destinées à être scellées dans son épaisseur en sécurisant ainsi la solidarisation du rail d'ancrage avec la structure interne de la planche S.In the embodiment shown, the section 1 carries fins 12 hooking extending in the transverse direction of the board S and intended to be sealed in its thickness thereby securing the securing of the anchor rail with the internal structure from the board S.

Le cas échéant, des ailettes complémentaires seront prévues aussi aux extrémités longitudinales du profilé pour renforcer le scellement, si nécessaire. Les ailettes 12 sont réalisées ici d'une seule pièce avec le corps du profilé 1 auquel elles sont raccordées latéralement et à mi-hauteur.If necessary, additional fins will also be provided at the longitudinal ends of the profile to reinforce the sealing, if necessary. The fins 12 are made here in one piece with the body of the section 1 to which they are connected laterally and at mid-height.

L'invention vise à perfectionner ce dispositif de fixation en complétant les moyens d'ancrage et de verrouillage précédemment décrits par des moyens spécifiques destinés à renforcer le blocage en translation de l'embase E sur la planche S.The invention aims to improve this fastening device by completing the anchoring and locking means described above by specific means for reinforcing the locking in translation of the base E on the board S.

Une fois le réglage de la position et/ou de l'orientation de l'embase E effectué, le surfeur procède à son verrouillage par vissage à bloc du pivot 3. Ce vissage a pour effet de caler et d'immobiliser l'élément d'ancrage T dans le rail 1.Once the adjustment of the position and / or the orientation of the base E performed, the surfer proceeds to its locking by screwing the pivot block 3. This screwing has the effect of blocking and immobilizing the element d anchoring T in the rail 1.

Toutefois, dans le temps, il apparaît souvent un léger jeu entre l'embase et la planche. Or ce jeu a tendance à s'amplifier tant avec les mouvements de déformations de la planche S qu'avec les vibrations générées par le glissement de la planche, les à-coups et les efforts importants qu'applique l'utilisateur sur les embases lors de l'utilisation de la planche S sur la neige ce qui peut conduire à un décalage longitudinal de la position de l'embase sur la planche.However, in time, it often appears a slight clearance between the base and the board. But this game has a tendency to amplify both with the movements of deformations of the board S with the vibrations generated by the sliding of the board, the jolts and the important efforts that the user applies on the bases during the use of the board S on the snow which can lead to a longitudinal shift of the position of the base on the board.

Afin de garantir la pérennité et la fiabilité du réglage longitudinal initial, il est donc nécessaire d'assurer un blocage ferme et durable en translation longitudinale de l'embase sur la planche.In order to guarantee the durability and the reliability of the initial longitudinal adjustment, it is therefore necessary to ensure a firm and lasting locking in longitudinal translation of the base on the board.

Dans cet objectif, l'invention prévoit de réaliser, d'une part, au moins une barrette et dans la forme illustrée ici, deux barrettes crantées 21, 22 destinées à être intégrées dans la planche S de façon affleurante (ou en légère dépression) et, d'autre part, au moins un secteur denté et ici deux secteurs dentés périphériques 41, 42 portés par la face inférieure du disque 4 de verrouillage de l'embase E.For this purpose, the invention provides on the one hand, at least one bar and in the form shown here, two notched bars 21, 22 intended to be integrated into the board S flush (or slight depression) and, on the other hand, at least one toothed sector and here two peripheral toothed sectors 41, 42 carried by the lower face of the locking disc 4 of the base E.

En effet, c'est le disque 4 qui a une position fixe et prédéterminée par rapport à la planche S tandis que l'embase E peut être mobile en rotation par rapport à la planche tant que le pivot central n'est pas verrouillé.Indeed, it is the disc 4 which has a fixed and predetermined position relative to the board S while the base E can be rotatable relative to the board as the central pivot is not locked.

Dans une variante de réalisation, une seule barrette crantée pourrait être suffisante et elle coopérerait, dans ce cas, avec un seul secteur denté porté par la face inférieure du disque 4.In an alternative embodiment, a single toothed bar could be sufficient and it would cooperate, in this case, with a single toothed sector carried by the underside of the disk 4.

Dans une autre variante, le dispositif de l'invention pourrait comprendre plus de deux barrettes crantées par rail et plus de deux secteurs dentés par disque.In another variant, the device of the invention could comprise more than two rail bars and more than two toothed sectors per disc.

Pour des raisons d'efficacité de la tenue mécanique, il est essentiel que les barrettes crantées 21, 22 s'étendent à distance du rail 1 et coopèrent chacune, par engrenage, avec l'un des deux secteurs dentés réalisés en vis à vis sur la face inférieure du disque 4.For reasons of efficiency of the mechanical strength, it is essential that the notched bars 21, 22 extend at a distance from the rail 1 and cooperate each, by gearing, with one of the two toothed sectors made opposite on the underside of the disc 4.

Cette disposition a, en outre, l'avantage d'offrir une meilleure stabilité de l'embase E du fait que l'action de l'élément d'ancrage central T est renforcée par l'emprise latérale des secteurs dentés 41, 42 dans les barrettes 21, 22, à la manière de piliers.This arrangement has, moreover, the advantage of offering a better stability of the base E because the action of the central anchoring element T is reinforced by the lateral grip of the toothed sectors 41, 42 in the bars 21, 22, in the manner of pillars.

Il est surtout important que les barrettes crantées soient distinctes et éloignées des épaulements 11 du rail 1 pour ne pas fragiliser le rail 1 et conserver une résistance suffisante à l'arrachement de l'élément d'ancrage T.It is especially important that the toothed bars are separate and away from the shoulders 11 of the rail 1 to not weaken the rail 1 and maintain a sufficient resistance to tearing of the anchoring element T.

De préférence, la distance séparant l'axe du rail 1 du bord des barrettes 21, 22 est supérieur à 20 mm, voire de préférence supérieur à 30mm et, en particulier, compris entre 30 et 40mm.Preferably, the distance separating the axis of the rail 1 from the edge of the bars 21, 22 is greater than 20 mm, preferably even greater than 30 mm, and in particular between 30 and 40 mm.

Comme illustré par les figures 2A, 3A et 3B, les crans 210, 220 des barrettes 21, 22 sont orientés transversalement et s'étendent sur toute la largeur des barrettes.As illustrated by Figures 2A , 3A and 3B , the notches 210, 220 of the bars 21, 22 are oriented transversely and extend over the entire width of the bars.

Les secteurs dentés 41, 42 sont, quant à eux, ménagés sur deux zones angulaires diamétralement opposées du pourtour du disque 4.The toothed sectors 41, 42 are, in turn, formed on two diametrically opposite angular zones around the periphery of the disc 4.

Pour permettre un engagement réciproque aisé, stable et résistant, les profils des dents 410, 420 et des crans 210, 220 sont complémentaires.To enable easy, stable and resistant mutual engagement, the profiles of the teeth 410, 420 and notches 210, 220 are complementary.

En outre, il est prévu que la largeur maximale des secteurs 41, 42 soit inférieure ou égale à celle des barrettes 21, 22 et la hauteur des dents 410, 420 de ces secteurs soit inférieure ou égale à la profondeur des crans 210, 220 de ces barrettes. Dans ces conditions et après verrouillage du dispositif de fixation, la face inférieure de l'embase reste parfaitement en contact d'appui avec la face supérieure de la planche.In addition, it is expected that the maximum width of the sectors 41, 42 is less than or equal to that of the bars 21, 22 and the height of the teeth 410, 420 of these sectors is less than or equal to the depth of the notches 210, 220 of these bars. Under these conditions and after locking of the fixing device, the lower face of the base remains in perfect contact with the upper face of the board.

De préférence, la largeur des barrettes 21, 22 est comprise entre 5 et 15mm et, de préférence, entre 9 et 11mm et leur hauteur est comprise entre 3 et 5mm tandis que la profondeur des crans 210, 220 (et donc la hauteur maximum des dents 410, 420) est comprise entre 3 et 4mm.Preferably, the width of the bars 21, 22 is between 5 and 15 mm, and preferably between 9 and 11 mm and their height is between 3 and 5 mm while the depth of the notches 210, 220 (and therefore the maximum height of teeth 410, 420) is between 3 and 4mm.

Le pas des crans, c'est à dire la largeur de leur base, est comprise entre 4 et 6mm et est, de préférence, de 5mm.The pitch of the notches, that is to say the width of their base, is between 4 and 6 mm and is preferably 5 mm.

La longueur des barrettes 21, 22 sera proche de la longueur du rail (à + ou - 20mm) dans le cas où le rail est destiné à recevoir une seule embase E pour assurer une plage de réglage suffisante.The length of the bars 21, 22 will be close to the length of the rail (at + or - 20mm) in the case where the rail is intended to receive a single base E to ensure a sufficient adjustment range.

Dans le cas particulier illustré dans le deuxième mode de réalisation, la longueur des barrettes 21,22 est plus courte que la longueur du rail 1 étant donné que le disque 4 comporte des butées latérales 44a,44b. Ces butées assurent le guidage dans la gorge du rail 1 et participent au blocage du disque 4 en rotation par rapport au rail 1.In the particular case illustrated in the second embodiment, the length of the bars 21,22 is shorter than the length of the rail 1 since the disc 4 has lateral stops 44a, 44b. These stops provide guidance in the groove of the rail 1 and participate in blocking the disk 4 in rotation with respect to the rail 1.

Cette configuration nécessite de prévoir un rail 1 plus long pour permettre le logement et le déplacement de ces butées 44a,44b.This configuration requires a longer rail 1 to allow the housing and movement of these stops 44a, 44b.

Dans une variante de réalisation sans ces butées latérales, le rail 1 et les barrettes 21,22 auraient alors approximativement même longueur.In an alternative embodiment without these lateral stops, the rail 1 and the bars 21,22 would then have approximately the same length.

Le profil des crans 210, 220 des barrettes 21,22 est symétrique pour faciliter le réglage par déplacement du disque 4 dans les deux sens pour qu'il soit aussi facile pour l'utilisateur de rapprocher ses pieds l'un de l'autre ou de les éloigner.The profile of the notches 210, 220 of the bars 21, 22 is symmetrical to facilitate adjustment by moving the disc 4 in both directions so that it is easier for the user to move his feet closer to each other or to move them away.

De préférence, ce profil est sensiblement identique à celui des dents 410, 420 des secteurs 41, 42 ; les extrémités des crans (et des dents) étant éventuellement arrondies pour les rendre moins agressives et moins sujettes à l'usure, comme illustré par les figures 5A et 5B.Preferably, this profile is substantially identical to that of the teeth 410, 420 of the sectors 41, 42; the ends of the notches (and teeth) being possibly rounded to make them less aggressive and less subject to wear, as illustrated by the Figures 5A and 5B .

Enfin le matériau constitutif des barrettes sera choisi pour sa rigidité, sa légèreté, sa compatibilité avec les différentes couches de la planche mais aussi pour ses bonnes propriétés de contact avec les dents des secteurs du disque 4.Finally the constituent material of the bars will be chosen for its rigidity, its lightness, its compatibility with the different layers of the board but also for its good properties of contact with the teeth of the sectors of the disc 4.

Une matière plastique du type polyamide ou polyuréthane éventuellement chargée de fibres composites ou même un matériau métallique pourra ainsi être avantageusement utilisé.A plastic material of the polyamide or polyurethane type optionally loaded with composite fibers or even a metallic material may thus advantageously be used.

Dans le mode de réalisation illustré par la figure 2A, le disque 4 est en une seule pièce et les secteurs dentés 41, 42 sont ménagés directement sur sa face inférieure. Le disque 4 est lui-même monté dans un logement évidé 40 ménagé sur la face supérieure de l'embase E et dont le pourtour est délimité par la couronne crénelée 4b de telle sorte que les dents 410, 420 fassent saillie vers le bas en direction des barrettes 21, 22.In the embodiment illustrated by the Figure 2A , the disc 4 is in one piece and the toothed sectors 41, 42 are formed directly on its underside. The disk 4 is itself mounted in a recessed housing 40 formed on the upper face of the base E and whose periphery is delimited by the crenellated crown 4b so that the teeth 410, 420 project downwards towards bars 21, 22.

Comme illustré par les figures 2B et 2C et, toujours dans ce même mode de réalisation, les secteurs dentés 41, 42 sont réalisés sous forme de bandes dont le bord extérieur 41a, 42a suit le pourtour du disque 4 tandis que le bord intérieur 41b, 42b s'étend de façon ortho-radiale, c'est-à-dire perpendiculaire à un diamètre du disque, ce bord intérieur étant rectiligne et les bords 41b et 42b étant parallèles entre eux.As illustrated by Figures 2B and 2C and, still in this same embodiment, the toothed sectors 41, 42 are in the form of strips whose outer edge 41a, 42a follows the periphery of the disc 4 while the inner edge 41b, 42b extends orthogonally. radial, that is to say perpendicular to a diameter of the disk, this inner edge being rectilinear and the edges 41b and 42b being parallel to each other.

Selon une variante non représentée, les secteurs dentés sont réalisés sous forme de deux bandes ortho-radiales dont les bords extérieurs et intérieures sont parallèles et dont l'écartement sur le disque par rapport au centre du disque est, de préférence, maximal.According to a variant not shown, the toothed sectors are made in the form of two ortho-radial strips whose outer and inner edges are parallel and whose spacing on the disk relative to the center of the disk is preferably maximum.

Dans le mode de réalisation illustré par les figures 3A, 3B et 3C, le disque 4 de verrouillage comprend un élément cylindrique indépendant 43 portant les secteurs dentés 41, 42 qui est rapporté, monté de façon coaxiale sous le disque 4 et fixé à celui-ci par des moyens de solidarisation de type vis.In the embodiment illustrated by the Figures 3A , 3B and 3C , the locking disc 4 comprises an independent cylindrical element 43 carrying the toothed sectors 41, 42 which is attached coaxially mounted under the disk 4 and fixed thereto by screw-type fastening means.

La figure 3A représente une embase E formée de plusieurs pièces E1, E2, E3 assemblées les unes aux autres en emprisonnant le disque 4. Cette embase est, en outre, pourvue d'un pivot axial composé lui-même de plusieurs éléments dont l'élément inférieur d'ancrage T et des éléments cylindriques montés au-dessus de l'embase. Aussi, on ne sortira pas du cadre de l'invention si l'embase présente des formes variées et/ou si elle est constituée de plusieurs pièces juxtaposées et/ou superposées.The figure 3A represents a base E formed of several pieces E1, E2, E3 assembled to each other by trapping the disc 4. This base is further provided with an axial pivot itself composed of several elements including the lower element anchoring T and cylindrical elements mounted above the base. Also, it will not depart from the scope of the invention if the base has various shapes and / or if it consists of several pieces juxtaposed and / or superimposed.

Dans une variante appliquée ici à l'élément rapporté 43, le bord intérieur 41b, 42b des secteurs dentés 41, 42 suit le pourtour circulaire du bord extérieur 41a, 42a sur une longueur angulaire comprise entre 20 et 40°, de préférence 35° comme illustré par la figure 3B.In a variant applied here to the insert 43, the inner edge 41b, 42b of the toothed sectors 41, 42 follows the circular periphery of the outer edge 41a, 42a over an angular length of between 20 and 40 °, preferably 35 ° as illustrated by the figure 3B .

Il serait possible, toutefois sans sortir du cadre de l'invention, de réaliser aussi les secteurs dentés selon les variantes décrites ci-dessus en référence aux figures 2B et 2C.It would be possible, however, without departing from the scope of the invention, to also produce the toothed sectors according to the variants described above with reference to the Figures 2B and 2C .

La planche selon l'invention qui comporte l'intégration de divers éléments constitutifs du dispositif de fixation de l'invention est décrite dans ce qui suit.The board according to the invention which comprises the integration of various constituent elements of the fastening device of the invention is described in the following.

Au moins un profilé rigide 1 formant rail et tel qu'illustré ici, deux profilés du type décrit ci-dessus sont intégrés à la structure de la planche S. Ce profilé est réalisé, de préférence, par usinage ou par emboutissage ou bien encore par extrusion d'une pièce en métal léger (aluminium,...) ou par moulage d'une pièce en matière plastique, éventuellement renforcée.At least one rigid profile 1 forming a rail and as illustrated here, two profiles of the type described above are integrated into the structure of the board S. This profile is preferably produced by machining or stamping or else by extrusion of a piece of light metal (aluminum, ...) or by molding a plastic part, possibly reinforced.

Il présente une section parallélépipèdique ouverte, partiellement, sur sa face supérieure en délimitant une gorge 10 formant glissière pour l'élément d'ancrage T de l'embase E. Cette gorge peut être réalisée soit avant le moulage de la planche S, soit peut être usinée après le moulage de la planche S.It has a parallelepipedal section open, partially, on its upper face delimiting a groove 10 forming a slide for the anchoring element T of the base E. This groove can be made either before the molding of the board S, or can be machined after molding the board S.

De manière traditionnelle et dans la forme illustrée, ce profilé 1 est avantageusement pourvu d'ailettes latérales 12 pour augmenter la tenue du rail 1 à l'arrachement.In the traditional way and in the illustrated form, this profile 1 is advantageously provided with lateral fins 12 to increase the resistance of the rail 1 to tearing.

Les deux barrettes rigides crantées 21, 22 du type décrit précédemment avec une matière rigide appropriée seront également intégrées à la structure de la planche S. Les crans pourront être réalisés soit avant le moulage, soit par usinage des barrettes après le moulage de la planche S.The two rigid rigid bars 21, 22 of the type described above with a suitable rigid material will also be integrated into the structure of the board S. The notches can be made either before molding or by machining the bars after the molding of the board S .

Selon une variante du procédé, il serait possible de réaliser le profilé de rail et les barrettes en une seule pièce en un même matériau rigide ayant les propriétés mécaniques requises, les barrettes étant alors réalisées au-delà des zones d'épaulement 11 du rail 1.According to a variant of the method, it would be possible to produce the rail section and the strips in one piece of the same rigid material having the required mechanical properties, the strips being then formed beyond the shoulder areas 11 of the rail 1 .

Une planche de surf est généralement fabriquée par moulage à chaud. Tous ses éléments constitutifs (semelle, carres, chants, couches supérieure et inférieure de renfort et noyau en bois ou polyuréthane,...) sont préparés avant le moulage. Les différentes couches de matériaux sont prédécoupées.A surfboard is usually made by hot molding. All its constituent elements (sole, edges, edges, upper and lower layers of reinforcement and wood core or polyurethane, ...) are prepared before molding. The different layers of materials are precut.

Le noyau de la planche, notamment s'il est en bois, est également prédécoupé et son épaisseur est ajustée à la courbe d'épaisseur de la planche S.The core of the board, especially if it is wood, is also precut and its thickness is adjusted to the thickness curve of the board S.

Ensuite, les différentes couches de matériaux sont empilées dans un moule dont le profil est adapté à la forme et aux dimensions de la planche de surf désirée.Then, the different layers of materials are stacked in a mold whose profile is adapted to the shape and dimensions of the desired surfboard.

Les couches de renfort en matériaux composites sont pré-encollées avec une résine. Lors du moulage, l'ensemble est appliqué en compression autour du noyau et porté à haute température. La résine qui polymérise assure ainsi la cohésion entre les différents éléments.The reinforcing layers made of composite materials are pre-glued with a resin. During molding, the assembly is applied in compression around the core and heated to high temperature. The polymerizing resin thus ensures cohesion between the different elements.

A la sortie du moule, la planche subit une opération de finition qui consiste, notamment, à enlever le surplus de matière sur tout le contour.At the outlet of the mold, the board undergoes a finishing operation which consists, in particular, to remove the excess material over the entire contour.

Selon le procédé de l'invention, il est prévu de ménager, dans le noyau en bois (ou polyuréthane) N de la planche et préalablement au moulage, une cavité centrale débouchant sur la face supérieure et au moins deux cavités latérales s'étendant à équi-distance et parallèlement à la cavité centrale (figure 4).According to the method of the invention, it is intended to provide, in the wood core (or polyurethane) N of the board and prior to molding, a central cavity opening on the upper face and at least two lateral cavities extending to equi-distance and parallel to the central cavity ( figure 4 ).

Ces cavités qui sont réalisées par découpe du noyau N ou enlèvement de matière, ont des profils et des dimensions permettant la mise en place des barrettes 21, 22 et du profilé 1 de telle sorte que ses ailettes 12 soient au contact du noyau N et que ses épaulements 11 s'étendent de façon sensiblement affleurante à la face supérieure de la planche, de même que les extrémités supérieures des crans 210, 220 des barrettes 21, 22.These cavities which are made by cutting the core N or removal of material, have profiles and dimensions for the establishment of the bars 21, 22 and the profile 1 so that its fins 12 are in contact with the core N and that its shoulders 11 extend substantially flush with the upper face of the board, as well as the upper ends of the notches 210, 220 of the bars 21, 22.

Les barrettes étant destinées à être intégrées dans la l'épaisseur de la planche et leur hauteur étant telle qu'elles pénètrent dans le noyau, la structure de la planche doit être adaptée pour garantir leur tenue mécanique sans compromettre son étanchéité dans la zone d'implantation. Ainsi, la structure de la planche S est modifiée dans la zone d'implantation des barrettes 21,22.The strips being intended to be integrated in the thickness of the board and their height being such that they penetrate into the core, the structure of the board must be adapted to guarantee their mechanical strength without compromising its sealing in the area of the board. implantation. Thus, the structure of the board S is modified in the area of implantation of the bars 21,22.

Une première structure de la planche est illustrée aux figures 4 et 5B. Dans cette variante, dans la zone de la barrette 21,22, le noyau N est interrompu et présente deux cavités dans lesquelles sont positionnés des inserts I en matière plastique de type ABS qui présentent eux-mêmes un logement pour recevoir chacune des barrettes 21,22.A first structure of the board is illustrated at Figures 4 and 5B . In this variant, in the zone of the bar 21,22, the core N is interrupted and has two cavities in which are positioned inserts I made of ABS plastic which themselves have a housing for receiving each of the bars 21, 22.

L'utilisation de cet insert plastique I permet d'assurer l'étanchéité de la structure de la planche S autour des parties inférieures et des côtés latéraux des barrettes, alors que le noyau bois n'aurait pas pu assurer cette étanchéité.The use of this plastic insert I makes it possible to seal the structure of the board S around the lower parts and the lateral sides of the bars, whereas the wood core could not ensure this tightness.

Bien entendu, d'autres moyens d'étanchéité pourraient être utilisés, le but étant de garantir l'absence d'infiltration d'eau entre la barrette et la structure de la planche.Of course, other sealing means could be used, the purpose being to ensure the absence of water infiltration between the bar and the structure of the board.

Au niveau des côtés supérieurs des barrettes, l'étanchéité est assurée par les renforts R2 et la couche de protection supérieure F qui viennent au contact de ces côtés.At the upper sides of the bars, the seal is provided by the reinforcements R2 and the upper protective layer F which come into contact with these sides.

Par ailleurs, le renfort inférieur R1 recouvre les faces inférieures du noyau N et de l'insert I. Dans la zone du rail 1, les couches de matériaux fibreux supérieures R2 et M emprisonnent les ailettes 12 du profilé 1 dans l'épaisseur de la planche tout en renforçant sa tenue à l'arrachement.Furthermore, the lower reinforcement R1 covers the lower faces of the core N and the insert I. In the region of the rail 1, the layers of upper fibrous materials R2 and M trap the fins 12 of the profile 1 in the thickness of the board while strengthening its resistance to tearing.

De manière connue, les couches inférieure R1 et supérieure R2 de renfort sont réalisées soit avec un matériau fibreux composite (tissu de fibres de verre, par exemple, enduit d'une résine polymère de type époxy), soit en aluminium, tandis que la couche de protection F est réalisée avec une matière transparente et est éventuellement pourvue d'un décor graphique.In known manner, the lower reinforcement layers R1 and R2 are made either with a composite fibrous material (glass fiber fabric, for example, coated with an epoxy-type polymer resin), or aluminum, while the layer F protection is made with a transparent material and is optionally provided with a graphic decoration.

De manière connue, au-dessous du renfort inférieur R1 est positionnée une semelle P dont ses côtés latéraux sont bordés par des carres (non représentées).In known manner, below the lower reinforcement R1 is positioned a sole P whose lateral sides are bordered by edges (not shown).

De façon connue, le procédé de fabrication par moulage conduit, lors de la polymérisation à chaud de la résine, à la stratification des couches fibreuses et, par suite, à la liaison et à la solidarisation des différents éléments constitutifs de la planche et du dispositif de fixation intégré.In a known manner, the molding manufacturing process leads, during the hot polymerization of the resin, to the stratification of the fibrous layers and, consequently, to the bonding and the joining of the various constituent elements of the board and the device. integrated fixation.

Dans une autre variante illustrée à la figure 5A, le noyau N n'est pas interrompu totalement comme dans la variante précédente mais il est simplement suffisamment évidé pour recevoir, dans les évidements, non seulement les barrettes 21,22 mais aussi au moins une couche de renfort R3 composée, par exemple, de fibres noyées dans de la résine et positionnée en dessous des barrettes 21,22 en assurant ainsi conjointement l'étanchéité entre les barrettes et le noyau N.In another variant illustrated in Figure 5A , the core N is not completely interrupted as in the previous variant but it is simply hollow enough to receive, in the recesses, not only the bars 21,22 but also at least one reinforcing layer R3 composed, for example, of fibers embedded in resin and positioned below the bars 21,22 thus ensuring together the seal between the bars and the core N.

La planche illustrée ici présente deux rails centraux alignés sur l'axe longitudinal de la planche et destinés à recevoir chacun une embase E.The board illustrated here has two central rails aligned on the longitudinal axis of the board and intended to each receive a base E.

On ne sortira pas du cadre de l'invention si ces deux rails se rejoignent pour former un seul rail central plus long, destiné à recevoir les deux embases.It will not depart from the scope of the invention if these two rails meet to form a single longer central rail for receiving the two bases.

Conjointement et afin de rendre compatibles la planche et le dispositif de fixation de l'invention, il est nécessaire de modifier l'embase traditionnelle et, plus particulièrement, le disque de verrouillage central de telle sorte que sa face inférieure porte au moins deux secteurs dentés périphériques destinés à coopérer avec les barrettes crantées déjà intégrées dans la planche.Together and in order to make compatible the board and the fixing device of the invention, it is necessary to modify the traditional base and, more particularly, the central locking disk so that its underside carries at least two toothed sectors. peripherals intended to cooperate with the notched bars already integrated in the board.

Dans ce but, il convient simplement, soit de remplacer le disque de verrouillage traditionnel par un disque modifié de même diamètre mais dont la face inférieure porte des secteurs dentés adaptés à coopérer avec les barrettes crantées, soit de lui adjoindre un élément cylindrique du type de l'élément 43 (figure 3A) à secteurs dentés, réalisé séparément puis rapporté et monté de façon coaxiale sous l'embase.For this purpose, it is simply necessary either to replace the traditional locking disk by a modified disk of the same diameter but whose lower face carries toothed sectors adapted to cooperate with the toothed bars, or to add a cylindrical element of the type of Element 43 ( figure 3A ) with toothed sectors, made separately and reported and mounted coaxially under the base.

L'invention a été plus spécialement décrite dans une application à une planche de glisse sur neige mais elle pourrait être reproduite de façon similaire pour être utilisée en relation avec une planche de glisse aquatique.The invention has been more specifically described in an application to a snow gliding board but it could be similarly reproduced for use in connection with an aquatic gliding board.
