Description

DISPOSITIF DE RETENUE D'UNE CHAUSSURE SUR UNE PLANCHE DE GLISSE DEVICE FOR RETAINING A SHOE ON A SNOWBOARD
L'invention concerne un dispositif de retenue d'une chaussure sur une planche de glisse, notamment sur une planche de surf de neige.The invention relates to a device for retaining a boot on a gliding board, in particular on a snowboard.
L'invention concerne aussi une chaussure pour la pratique de la glisse, notamment la pratique du surf de neige, et une planche de glisse notamment pour la pratique du surf de neige.The invention also relates to a shoe for the practice of gliding, in particular the practice of snowboarding, and a board of gliding in particular for the practice of snowboarding.
Le surf de neige est un sport de glisse qui se pratique au moyen d'une planche en forme de plaque, dont l'extrémité avant est relevée pour former la spatule. Certaines planches ont aussi l'extrémité arrière relevée. Le skieur est relié à la planche par l'intermédiaire de deux éléments de retenue qui retiennent chacune de ses chaussures. Les éléments de retenue sont généralement décalés suivant l'axe longitudinal médian de la plaque et ils forment avec cet axe un angle de 5 à 90 degrés d'un côté ou de l'autre de cet axe. Cet angle ainsi que la distance entre les deux éléments de retenue peuvent être réglables.Snowboarding is a sliding sport that is practiced by means of a plate-shaped board, the front end of which is raised to form the tip. Some boards also have the rear end raised. The skier is connected to the board by means of two retaining elements which hold each of his boots. The retaining elements are generally offset along the median longitudinal axis of the plate and they form an angle of 5 to 90 degrees with this axis on one side or the other of this axis. This angle as well as the distance between the two retaining elements can be adjustable.
Il existe deux grandes familles d'éléments de retenue des chaussures sur la planche, selon que les chaussures sont de type rigide, ou de type souple. Pour les chaussures de type rigide les éléments de retenue comprennent généralement une plaque sur laquelle la semelle de chaussure est en appui. A chaque extrémité de la plaque, la chaussure est retenue par un étrier qui prend prise sur l'embout avant ou arrière de la chaussure.There are two main families of shoe retention elements on the board, depending on whether the shoes are of the rigid type, or of the flexible type. For rigid type shoes, the retaining elements generally comprise a plate on which the shoe sole is supported. At each end of the plate, the shoe is retained by a stirrup which takes hold on the front or rear end of the shoe.
Un tel dispositif est par exemple connu d'après la demande de brevet français publiée sous le numéro 2669237.Such a device is for example known from the French patent application published under the number 2669237.
Un autre dispositif de ce type est connu d'après la demande de brevet européen publiée sous le numéro 396 133. Ce dispositif comprend en plus une plaque intermédiaire qui est reliée à la planche de glisse par une liaison de type déclenchable. La chaussure est cependant retenue sur la plaque au moyen d'étriers traditionnels.Another device of this type is known from European patent application published under number 396 133. This device further comprises an intermediate plate which is connected to the gliding board by a link of the triggerable type. The shoe is however retained on the plate by means of traditional stirrups.
On connaît également, par exemple d'après la demande de brevet français publiée sous le numéro 2 592 807 un élément de retenue pour des chaussures de type souple, c'est à dire des chaussures qui s'apparentent à des bottes. Ces éléments de fixation comprennent généralement une coque rigide qui est assemblée à la surface de la planche de glisse et à l'intérieur de laquelle la botte est insérée et emprisonnée.There is also known, for example from the French patent application published under number 2,592,807, a retaining element for shoes of the flexible type, that is to say shoes which are similar to boots. These fasteners generally include a rigid shell which is assembled on the surface of the gliding board and inside which the boot is inserted and trapped.
Les éléments de retenue actuellement connus présentent l'inconvénient d'être encombrants, ou bien dans le sens de la longueur de la chaussure ou bien dans le sens de la hauteur. En outre, en dehors du réglage d'orientation des chaussures par rapport à la direction longitudinale de la planche, ils nécessitent des réglages d'adaptation à la chaussure du surfeur, à sa longueur principalement.The currently known retaining elements have the disadvantage of being bulky, either in the direction of the length of the shoe or in the direction of the height. In addition, apart from the adjustment of orientation of the shoes relative to the longitudinal direction of the board, they require adjustments of adaptation to the shoe of the surfer, mainly to its length.
En outre, les éléments de retenue actuellement connus occupent une surface importante de la planche, et de ce fait perturbent sa flexion et/ou sa torsion au cours de la glisse.In addition, the currently known retaining elements occupy a large surface of the board, and therefore disturb its bending and / or torsion during gliding.
Un des buts de l'invention est de proposer un dispositif de retenue d'une chaussure sur une planche de glisse qui présente un encombrement réduit.One of the aims of the invention is to propose a device for retaining a boot on a gliding board which has a reduced bulk.
Un autre but de l'invention est de proposer un dispositif de retenue vers la planche qui assure une bonne transmission des efforts que le surfeur produit au cours de la glisse. Un autre but de l'invention est de proposer un dispositif de retenue dont la construction est particulièrement simple.Another object of the invention is to propose a retaining device towards the board which ensures good transmission of the forces which the surfer produces during the gliding. Another object of the invention is to provide a retaining device whose construction is particularly simple.
Un autre but de l'invention est de proposer un dispositif de retenue qui peut être adapté sans réglage particulier à des chaussures de longueur et de volume différents.Another object of the invention is to provide a retaining device which can be adapted without particular adjustment to shoes of different length and volume.
D'autres but et avantages de l'invention apparaîtront au cours de la description qui va suivre, cette description étant toutefois donnée à titre indicatif, et non limitatif.Other objects and advantages of the invention will appear during the description which follows, this description being however given by way of indication, and not limitation.
Le dispositif de retenue d'une chaussure sur une planche de glisse selon l'invention comprend un élément de retenue associé à la planche coopérant avec un élément de retenue complémentaire associé à la chaussure, l'ensemble assurant une liaison entre la chaussure et la planche suivant les différents degrés de liberté de la chaussure par rapport à la planche.The device for retaining a shoe on a sliding board according to the invention comprises a retaining element associated with the board cooperating with a complementary retaining element associated with the shoe, the assembly ensuring a connection between the shoe and the board according to the different degrees of freedom of the shoe relative to the board.
Il est caractérisé par le fait qu'il comprend pour l'un des éléments un moyen définissant une rainure et pour l'autre élément un moyen définissant une nervure, la nervure et la rainure présentant des formes complémentaires pour pouvoir coopérer par emboîtement, qu'il comprend aussi pour l'un des éléments un moyen d'accrochage et pour l'autre un moyen de retenue formant un verrou amovible pour retenir activement la nervure emboîtée dans la rainure au moins selon la direction d'emboîtement, et qu'il comprend par ailleurs un moyen de commande pour au moins ouvrir le verrou de façon volontaire.It is characterized in that it comprises, for one of the elements, a means defining a groove and for the other element, a means defining a rib, the rib and the groove having complementary shapes in order to be able to cooperate by interlocking, that it also includes, for one of the elements, a hooking means and for the other, a retaining means forming a removable lock for actively retaining the rib fitted into the groove at least in the direction of fitting, and which it comprises also a control means to at least open the lock voluntarily.
L'invention sera mieux comprise en se référant à la description ci-dessous, ainsi qu'aux dessins en annexe qui en font partie intégrante.The invention will be better understood by referring to the description below, as well as to the accompanying drawings which form an integral part thereof.

La figure 10 est une vue de dessus de l'élément de retenue associé à la planche représenté dans la figure 9.FIG. 9 also illustrates another variant implementation of the invention. FIG. 10 is a top view of the retaining element associated with the board shown in FIG. 9.
Dans la figure 1 , on a représenté schématiquement vue de dessus une planche de surf de neige 1. La planche se présente sous la forme d'une plaque allongée suivant une direction longitudinale médiane 2. Les bords latéraux de la planche sont le plus souvent incurvés suivant ce qui est appelé de façon courante des lignes de cotes.In Figure 1, there is schematically shown from above a snowboard 1. The board is in the form of an elongated plate in a longitudinal longitudinal direction 2. The lateral edges of the board are most often curved following what is commonly called dimension lines.
Généralement, l'extrémité avant 3 de la planche est relevée pour former la spatule. L'extrémité arrière peut également être relevée, selon la nature de la discipline de glisse pratiquée.Generally, the front end 3 of the board is raised to form the spatula. The rear end can also be raised, depending on the nature of the sliding discipline practiced.
Le surfeur est relié à la planche 1 par l'intermédiaire de ses deux chaussures qui sont retenues à la surface supérieure de la planche par des dispositifs de retenue. Habituellement, les chaussures du surfeur sont retenues l'une à côté de l'autre suivant la direction longitudinale médiane 2, dans la zone centrale de la planche, à une distance approximative de 45 centimètres l'une de l'autre. On a schématisé en 4 et 5 leur position. Les deux chaussures sont orientées respectivement selon des directions 6 et 7 qui sont orientées en oblique par rapport à la direction 2. Les angles d'orientation varient selon les cas entre 90 et 5 degrés d'un côté ou de l'autre de la direction longitudinale selon que le surfeur est de nature "goofy" ou "regular". En général, ces angles sont réglables. L'écartement des chaussures peut aussi être réglable. La largeur de la planche dans la zone centrale est voisine de la longueur de la chaussure ou inférieure à cette longueur.The surfer is connected to the board 1 by means of his two shoes which are retained on the upper surface of the board by retaining devices. Usually, the shoes of the surfer are held next to each other in the longitudinal middle direction 2, in the central area of the board, at a distance of approximately 45 centimeters from each other. We have schematized in 4 and 5 their position. The two shoes are oriented respectively in directions 6 and 7 which are oriented obliquely to direction 2. The angles of orientation vary depending on the case between 90 and 5 degrees on one side or the other of the direction longitudinal depending on whether the surfer is "goofy" or "regular" in nature. In general, these angles are adjustable. The shoe spacing can also be adjustable. The width of the board in the central area is close to or less than the length of the shoe.
Naturellement ceci n'est donné qu'à titre indicatif et n'a pas de valeur limitative pour l'invention. Il existe en effet de nombreux modes de réalisation d'une telle planche de glisse, en particulier de nombreuses formes différentes, symétriques ou dissymétriques adaptés notamment au gabarit du surfeur et à la discipline de glisse pratiquée.Naturally, this is only given for information and has no limiting value for the invention. There are indeed many embodiments of such a gliding board, in particular many different forms, symmetrical or asymmetrical, adapted in particular to the size of the surfer and to the sliding discipline practiced.
Selon l'invention, chaque chaussure est retenue sur la planche par un dispositif de retenue. Le dispositif de retenue comprend un élément associé à la chaussure et un élément associé à la planche. L'un des éléments présente un moyen formant une nervure, l'autre élément présente un moyen formant une rainure. La nervure et la rainure présentent en section des formes complémentaires pour s'emboîter l'une dans l'autre. De préférence, ces formes assurent un rattrapage automatique de jeu. Le dispositif comprend en outre un moyen de verrouillage pour maintenir la nervure emboîtée dans la rainure.According to the invention, each shoe is retained on the board by a retaining device. The retainer includes an element associated with the shoe and an element associated with the board. One of the elements has a means forming a rib, the other element has a means forming a groove. The rib and the groove have in section complementary shapes to fit into one another. Preferably, these forms provide automatic backlash. The device further comprises a locking means for maintaining the rib fitted into the groove.
La figure 2 illustre de façon schématique une première mise en oeuvre de l'invention. Cette figure représente en perspective un élément de retenue 10 associé à la planche et un élément de retenue 11 associé à la semelle de chaussure.FIG. 2 schematically illustrates a first implementation of the invention. This figure shows in perspective a retaining element 10 associated with the board and a retaining element 11 associated with the shoe sole.
L'élément de retenue 10 se présente sous la forme d'une nervure 12 orientée selon la direction longitudinale définie par la semelle de chaussure, avec dans sa partie inférieure une embase 13 destinée à la solidarisation de l'élément à la planche. De façon complémentaire, l'élément de retenue 11 présente une rainure longitudinale 15, qui, dans l'exemple illustré débouche vers l'avant et vers l'arrière. Ceci est destiné à faciliter l'évacuation de la neige et n'est pas limitatif. La nervure 12 et la rainure 15 présentent une longueur voisine. Cette longueur est du même ordre de grandeur que la longueur de la chaussure. La figure 3 représente en coupe transversale l'élément 11 emboîté sur l'élément 10. Ainsi que cela est visible, de préférence, les flancs latéraux 17, 18 de la nervure 12 sont inclinés par rapport, à un plan vertical, de telle façon que la nervure s'élargisse vers le bas. Les flancs latéraux 19 et 20 de la nervure sont également inclinés de façon complémentaire.The retaining element 10 is in the form of a rib 12 oriented in the longitudinal direction defined by the shoe sole, with in its lower part a base 13 intended for securing the element to the board. In a complementary manner, the retaining element 11 has a longitudinal groove 15, which, in the example illustrated opens out forwards and backwards. This is intended to facilitate the evacuation of snow and is not limiting. The rib 12 and the groove 15 have a similar length. This length is of the same order of magnitude as the length of the shoe. 3 shows cross-sectional element 11 fitted over the element 10. As can be seen, preferably, the lateral flanks 17, 18 of the rib 12 are inclined relative to a vertical plane, in such a way let the rib widen down. The lateral flanks 19 and 20 of the rib are also inclined in a complementary manner.
De préférence, les largeurs de la nervure et de la rainure sont déterminées pour que l'ajustement et l'appui entre la nervure et la rainure selon une direction verticale se fasse par l'appui relatif de leurs flancs latéraux respectifs.Preferably, the widths of the rib and of the groove are determined so that the adjustment and the support between the rib and the groove in a vertical direction is effected by the relative support of their respective lateral flanks.
Toutefois, ceci n'est pas limitatif, et l'appui vertical entre les deux éléments pourrait être aussi réalisé par coopération du sommet 21 de la nervure avec le fond 22 de la rainure, ou bien par les bords 23 de la rainure avec les bords latéraux de l'embase 13, ou tout autre moyen approprié. Par exemple, les bords latéraux 23 de la rainure pourraient être équipés au moins localement de bandes ou de patins 25 de matériau élastiquement déformable qui assurent à la fois une reprise partielle des efforts verticaux, un rattrapage de jeu, et le cas échéant un léger jeu élastique au cours de la glisse. Ces bandes ou patins peuvent être aussi utiles au cours de la marche.However, this is not limiting, and the vertical support between the two elements could also be achieved by cooperation of the top 21 of the rib with the bottom 22 of the groove, or else by the edges 23 of the groove with the edges side of the base 13, or any other suitable means. For example, the lateral edges 23 of the groove could be fitted at least locally with bands or pads 25 of elastically deformable material which ensure both a partial recovery of vertical forces, a take-up of play, and if necessary a slight play elastic during gliding. These bands or skates can also be useful during walking.
Le dispositif illustré dans les figures comprend par ailleurs un moyen de verrouillage pour maintenir l'emboîtement de la nervure et de la rainure. Les figures représentent à cet effet pour l'élément 11 un profilé transversal 28 qui est situé vers le milieu de la nervure, et qui s'étend entre ses deux bords latéraux, vers le milieu de la hauteur. Le profilé 28 est par exemple circulaire, mais il peut aussi présenter en section toute autre forme.The device illustrated in the figures also comprises a locking means for maintaining the interlocking of the rib and the groove. The figures show for this purpose for the element 11 a transverse section 28 which is located towards the middle of the rib, and which extends between its two lateral edges, towards the middle of the height. The profile 28 is for example circular, but it can also have any other shape in section.
La nervure 12 présente de son côté, pour recevoir le profilé 28, une encoche 30 orientée selon une direction transversale. De préférence, ainsi que cela est visible, l'encoche 30 est évasée vers le haut, pour faciliter le guidage du profilé 28 lors de son introduction.The rib 12 has on its side, to receive the section 28, a notch 30 oriented in a transverse direction. Preferably, as is visible, the notch 30 is flared upward, to facilitate the guiding of the profile 28 during its introduction.
La nervure 12 présente par ailleurs une sorte de targette 31 , qui est mobile selon une direction longitudinale, et qui est positionnée pour pouvoir bloquer le profilé 28 au fond de l'encoche 30. Par exemple, la targette se trouve vers le milieu de la largeur de la nervure 12, elle est montée coulissante selon une direction longitudinale dans un logement 32, et elle est rappelée élastiquement en position d'obturation de l'encoche 30 par un ressort 33.The rib 12 also has a sort of bolt 31, which is movable in a longitudinal direction, and which is positioned so as to be able to block the profile 28 at the bottom of the notch 30. For example, the bolt is located towards the middle of the width of the rib 12, it is slidably mounted in a longitudinal direction in a housing 32, and it is resiliently returned to the position in which the notch 30 is closed by a spring 33.
Une tirette 35 ou tout autre moyen approprié est reliée à la targette 31. La tirette permet d'escamoter momentanément la targette dans la nervure pour libérer l'ouverture de l'encoche 30. La tirette pourrait aussi être remplacée par un levier latéral ou par tout autre moyen approprié pour manoeuvrer la targette, notamment un moyen souple tel qu'un câble.A zipper 35 or any other suitable means is connected to the bolt 31. The zipper makes it possible to temporarily retract the bolt in the rib to release the opening of the notch 30. The zipper could also be replaced by a lateral lever or by any other suitable means for operating the targette, in particular a flexible means such as a cable.
Avantageusement, la targette 31 présente une surface supérieure inclinée qui permet un engagement automatique du profilé dans l'encoche par une pression verticale du profilé sur la targette. Le cas échéant, la surface inférieure de la targette est légèrement inclinée pour assurer un rattrapage de jeu automatique sur le profilé 28. De plus, la face de l'encoche opposée à la targette peut présenter une ouverture dans laquelle l'extrémité de la targette s'engage en position d'obturation de l'encoche.Advantageously, the bolt 31 has an inclined upper surface which allows automatic engagement of the profile in the notch by vertical pressure of the profile on the bolt. If necessary, the lower surface of the bolt is slightly inclined to ensure automatic backlash on the profile 28. In addition, the face of the notch opposite the bolt may have an opening in which the end of the bolt engages in the closed position of the notch.
Sous le niveau de la tirette, l'encoche présente en section des dimensions très voisines de celles du profilé 28 pour assurer sa retenue quasiment sans jeu. Le mode d'utilisation du dispositif est le suivant. L'élément 11 associé à la chaussure constitue par exemple la partie inférieure d'une semelle de chaussure, qui est surmontée d'une coque ou d'une tige appropriée. Cette coque ou cette tige ne sont pas représentées dans les différentes figures. L'élément 10 est solidarisé à la surface de la planche de glisse selon une orientation souhaitée. La solidarisation est réalisée par tout moyen approprié. Eventuellement, l'orientation de l'élément 10 par rapport à la direction longitudinale médiane 2 de la planche est réglable. Tout autre réglage peut aussi être ajouté notamment un réglage d'inclinaison de la chaussure par rapport à une direction perpendiculaire à la planche, ou un réglage de la distance séparant l'élément 10 de l'autre élément de retenue de l'autre chaussure.Below the level of the pull tab, the notch has in section dimensions very close to those of the section 28 to ensure its retention almost without play. The mode of use of the device is as follows. The element 11 associated with the shoe constitutes for example the lower part of a shoe sole, which is surmounted by a shell or an appropriate upper. This shell or this rod are not shown in the various figures. The element 10 is secured to the surface of the gliding board in a desired orientation. The joining is carried out by any appropriate means. Optionally, the orientation of the element 10 relative to the median longitudinal direction 2 of the board is adjustable. Any other adjustment can also be added, in particular an adjustment of inclination of the boot relative to a direction perpendicular to the board, or an adjustment of the distance separating the element 10 from the other retaining element of the other shoe.
Au chaussage, le surfeur place sa chaussure pour qu'elle s'emboîte sur la nervure 12, et que le profilé 28 se présente à l'ouverture de l'encoche 30. Le cas échéant, il peut faciliter ce positionnement par un mouvement de basculement d'avant en arrière de sa chaussure. Par une pression verticale de sa chaussure, le surfeur oblige la targette 31 à s'ouvrir permettant ainsi la pénétration puis le verrouillage du profilé dans l'encoche. La coopération entre la nervure et la rainure d'une part, le profilé, l'encoche et la targette d'autre part assure une liaison entre les deux éléments de retenue suivant tous les degrés de liberté. En particulier, le moyen de verrouillage, c'est à dire le profilé 28, l'encoche 30 et la targette 31 assurent une liaison suivant la direction verticale d'emboîtement et suivant la direction longitudinale définie par la nervure.When putting on, the surfer places his shoe so that it fits on the rib 12, and so that the section 28 is presented at the opening of the notch 30. If necessary, it can facilitate this positioning by a movement of tilting back and forth of his shoe. By vertical pressure of his shoe, the surfer forces the bolt 31 to open, thus permitting penetration and then locking of the profile in the notch. The cooperation between the rib and the groove on the one hand, the profile, the notch and the bolt on the other hand ensures a connection between the two retaining elements according to all the degrees of freedom. In particular, the locking means, that is to say the section 28, the notch 30 and the bolt 31 provide a connection in the vertical direction of fitting and in the longitudinal direction defined by the rib.
Pour libérer volontairement sa chaussure, le surfeur exerce une traction sur la tirette 32, permettant ainsi la libération du profilé 28 hors de l'encoche 30.To voluntarily release his shoe, the surfer exerts traction on the pull tab 32, thus allowing the profile 28 to be released from the notch 30.
Selon l'invention, la nervure et la rainure qui coopèrent ensemble peuvent avoir toute forme appropriée, et n'ont pas nécessairement suivant leur longueur une section transversale de dimensions constantes. De plus, la nervure et/ou la rainure ne sont pas nécessairement continues suivant leur direction principale.According to the invention, the rib and the groove which cooperate together can have any suitable shape, and do not necessarily have, along their length, a cross section of constant dimensions. In addition, the rib and / or the groove are not necessarily continuous along their main direction.
Pour illustrer cela, la figure 5 représente l'élément de retenue 10 sous la forme d'une nervure 40 dont les flancs latéraux 41 , 42 sont sensiblement bombés et présentent globalement des inclinaisons dissymétriques par rapport à un plan vertical et longitudinal médian schématisé en 46. De plus, le sommet 43 de la nervure est incliné par rapport à un plan horizontal. La figure 5 représente aussi des évidements 44 et 45 répartis suivant la longueur de la nervure. Ces différentes variantes peuvent être mis en oeuvre ensemble, ou séparément.To illustrate this, FIG. 5 represents the retaining element 10 in the form of a rib 40, the lateral flanks 41, 42 of which are substantially convex and generally have asymmetrical inclinations with respect to a vertical and longitudinal median plane shown diagrammatically at 46 In addition, the apex 43 of the rib is inclined relative to a horizontal plane. FIG. 5 also shows recesses 44 and 45 distributed along the length of the rib. These different variants can be implemented together, or separately.
Dans cette variante, le moyen de verrouillage est représenté avec deux targettes 47 et 48, situées au niveau des nervures 44, 45, dont l'ouverture est commandée par un levier latéral 19. La liaison du levier aux targettes est de la portée de l'homme du métier. La chaussure dans ce cas présente un moyen d'accrochage en deux parties, situées à l'avant et à l'arrière de la semelle. Ces parties coopèrent avec les targettes 47, 48 et ont une distance constante quelque soit la longueur de la chaussure.In this variant, the locking means is shown with two bolts 47 and 48, located at the ribs 44, 45, the opening of which is controlled by a lateral lever 19. The connection of the lever to the bolts is within the scope of the skilled in the art. The shoe in this case has a hooking means in two parts, located at the front and at the rear of the sole. These parts cooperate with the pins 47, 48 and have a constant distance whatever the length of the shoe.
D'autres adaptations pourraient aussi être adoptées. Par exemple, la nervure pourrait présenter vue de dessus une forme triangulaire, ou présenter une forme triangulaire en section sur au moins une partie de sa longueur. La nervure pourrait aussi avoir plusieurs branches secondaires, de façon par exemple à former un "T", un "Y" ou toute autre forme appropriée. On peut aussi être amené à équiper localement les différentes faces de la rainure et de la nervure de formes complémentaires faisant office de détrompeur, c'est à dire empêchant l'engagement de la chaussure sur l'élément associé à la planche dans un sens qui n'est pas le bon.Other adaptations could also be adopted. For example, the rib could have a triangular shape seen from above, or have a triangular shape in section over at least part of its length. The rib could also have several secondary branches, so example to form a "T", a "Y" or any other suitable form. It may also be necessary to locally equip the different faces of the groove and of the rib with complementary shapes acting as a polarizer, that is to say preventing the engagement of the shoe on the element associated with the board in a direction which is not the right one.
Naturellement l'autre élément de retenue présente une rainure dont les dimensions en section sont appropriées à celles de la nervure.Naturally the other retaining element has a groove whose dimensions in section are appropriate to those of the rib.
De préférence, la nervure et la rainure assurent une immobilisation de la chaussure sur la planche autour d'une direction verticale et selon une direction transversale à la direction principale de la nervure. Le moyen de verrouillage assure quant à lui une liaison autour selon une direction verticale vers le haut et selon la direction principale de la nervure. Eventuellement cette liaison longitudinale peut être réalisée par l'emboîtement de la nervure et de la rainure, du fait de leur forme ou, par exemple, par des nervures secondaires transversales qui coopèrent avec des rainures ou des évidements secondaires.Preferably, the rib and the groove immobilize the boot on the board around a vertical direction and in a direction transverse to the main direction of the rib. The locking means in turn provides a connection around in a vertical direction upwards and in the main direction of the rib. Optionally, this longitudinal connection can be achieved by the interlocking of the rib and the groove, due to their shape or, for example, by transverse secondary ribs which cooperate with secondary grooves or recesses.
La figure 6 représente une autre variante de réalisation. Selon cette variante, l'élément de retenue 11 associé à la chaussure se présente globalement comme une nervure composée de deux parties 51 et 52, respectivement situées à l'avant et l'arrière de l'élément dans l'alignement l'une de l'autre. Les parties de nervure 51 et 52 sont limitées latéralement par des rebords latéraux, respectivement 54, 55, 56, 57. Ces rebords sont de préférence incurvés vers l'avant et vers l'arrière pour faciliter la marche. Sur un même côté de l'élément, les rebords 55 et 57, 54 et 56 sont séparés par des évidements.Figure 6 shows another alternative embodiment. According to this variant, the retaining element 11 associated with the shoe is generally presented as a rib composed of two parts 51 and 52, respectively located at the front and the rear of the element in alignment with one of the other. The rib parts 51 and 52 are bounded laterally by lateral edges, respectively 54, 55, 56, 57. These edges are preferably curved forward and backward to facilitate walking. On the same side of the element, the flanges 55 and 57, 54 and 56 are separated by recesses.
L'élément 10 associé à la planche se présente comme une nervure limitée latéralement par deux rebords latéraux 60 et 61. Entre les rebords 60 et 61 selon une direction transversale, l'élément 10 présente un evidement longitudinal 62. L'évidement 62 débouche vers l'avant et vers l'arrière. La longueur de la nervure est voisine de la longueur de la nervure formée par les rebords latéraux 54 à 57 ou inférieure.The element 10 associated with the board is presented as a rib laterally bounded by two lateral flanges 60 and 61. Between the flanges 60 and 61 in a transverse direction, the element 10 has a longitudinal recess 62. The recess 62 opens out towards forward and backward. The length of the rib is close to the length of the rib formed by the side edges 54 to 57 or less.
Comme dans le cas précédent, les dimensions d'une section transversale de la nervure formée par les rebords longitudinaux 60 et 61 sont complémentaires de celles de la rainure formée par les rebords 54 à 57 pour assurer un emboîtement de la nervure dans la rainure. De préférence, les flancs de la nervure et de la rainure sont inclinés par rapport à un plan vertical.As in the previous case, the dimensions of a cross section of the rib formed by the longitudinal flanges 60 and 61 are complementary to those of the groove formed by the flanges 54 to 57 to ensure an engagement of the rib in the groove. Preferably, the sides of the rib and of the groove are inclined relative to a vertical plane.
Toutefois, la forme et les dimensions d'une section transversale ne sont pas limitatives pour l'invention. On peut aussi mettre en oeuvre des variantes de forme et d'inclinaison des flancs telles que celles qui ont été décrites précédemment.However, the shape and dimensions of a cross section are not limiting for the invention. It is also possible to use variants of the shape and inclination of the sidewalls such as those which have been described previously.
Le dispositif présente par ailleurs un moyen de verrouillage. Selon la figure 6, l'élément 11 présente dans sa partie centrale, entre les parties 51 et 52, une forme 64 qui s'étend en relief selon une direction longitudinale sur le fond de la rainure. Cette forme en relief est destinée à être engagée dans l'évidement 62 de la nervure, entre les rebords longitudinaux 60 et 61. Elle présente en section transversale des dimensions inférieures ou égales à celles de l'évidement 62 pour pouvoir être engagée dans l'évidement. Toutefois, un ajustement de ces formes entre elles n'est pas indispensable. Latéralement, la forme en relief 64 présente deux plots latéraux 66 et 67, qui s'étendent transversalement, de telle façon que la distance entre leurs extrémités soit approximativement égale à la largeur de la nervure. Eventuellement, les plots 66 et 67 sont les extrémités d'un profil dont la partie centrale est noyée dans la forme en relief 64.The device also has a locking means. According to Figure 6, the element 11 has in its central part, between the parts 51 and 52, a shape 64 which extends in relief in a longitudinal direction on the bottom of the groove. This relief shape is intended to be engaged in the recess 62 of the rib, between the longitudinal edges 60 and 61. It has in cross section dimensions less than or equal to those of the recess 62 so that it can be engaged in the obviously. However, an adjustment of these forms between them is not essential. Laterally, the relief shape 64 has two lateral studs 66 and 67, which extend transversely, so that the distance between their ends is approximately equal to the width of the rib. Optionally, the studs 66 and 67 are the ends of a profile, the central part of which is embedded in the relief shape 64.
De façon complémentaire, les rebords longitudinaux 60, 61 de la nervure présentent deux encoches 68 et 69, qui sont destinées à recevoir les plots latéraux 66 et 67.In addition, the longitudinal edges 60, 61 of the rib have two notches 68 and 69, which are intended to receive the lateral studs 66 and 67.
Le moyen de verrouillage comprend par ailleurs deux portions de targette 70 et 71 qui sont guidées dans les rebords latéraux 60 et 61. Ces portions de targettes ont la même fonction que la targette précédemment décrite. Elles peuvent être manoeuvrées par une tirette 73. Par exemple, la tirette et les portions de targette sont constituées par un profilé plié en "U", dont les deux branches latérales sont guidées à l'intérieur des rebords longitudinaux 60 et 61. Ceci n'est pas limitatif, et les portions de targette pourraient manoeuvrées par un levier latéral ou par tout autre moyen approprié.The locking means also comprises two bolt portions 70 and 71 which are guided in the lateral flanges 60 and 61. These bolt portions have the same function as the bolt previously described. They can be operated by a pull tab 73. For example, the pull tab and the bolt portions consist of a section folded in a "U" shape, the two lateral branches of which are guided inside the longitudinal edges 60 and 61. This does not 'is not limiting, and the bolt portions could be operated by a lateral lever or by any other appropriate means.
Comme dans le cas précédent, les portions de targette peuvent être rappelées en position d'obturation des encoches par un moyen élastique tel qu'un ressort, les encoches 68 et 69 peuvent être évasées vers le haut, et les portions de targettes peuvent être équipées de rampes pour faciliter l'introduction et le verrouillage automatique des plots 66 et 67 dans les encoches, et le cas échéant pour rattraper les jeux à ce niveau.As in the previous case, the bolt portions can be recalled in the closed position of the notches by an elastic means such as a spring, the notches 68 and 69 can be flared upward, and the bolt portions can be fitted ramps to facilitate the introduction and automatic locking of the studs 66 and 67 in the notches, and if necessary to make up for the clearances at this level.
La figure 8 représente une autre variante de réalisation. Selon cette variante, l'élément 11 associé à la chaussure se présente sous la forme d'une rainure 74 orientée selon la largeur de l'élément 11. La rainure débouche latéralement de chaque coté de la semelle, et elle est limitée à l'avant et à l'arrière de la chaussure par deux flancs inclinés 75 et 76. Dans l'exemple illustré, la distance entre les flancs 75 et 76 est supérieure à la largeur de l'élément 11 dans sa partie centrale.Figure 8 shows another alternative embodiment. According to this variant, the element 11 associated with the shoe is in the form of a groove 74 oriented along the width of the element 11. The groove opens laterally on each side of the sole, and it is limited to the front and rear of the shoe by two inclined sides 75 and 76. In the example illustrated, the distance between the sides 75 and 76 is greater than the width of the element 11 in its central part.
L'élément 10 associé à la planche présente une nervure 78 orientée selon la largeur de l'élément. La nervure 78 est limitée sur l'avant et l'arrière de la chaussure par deux flancs inclinés 79 et 80 qui sont destinés à coopérer avec les flancs 75 et 76 de la rainure.The element 10 associated with the board has a rib 78 oriented along the width of the element. The rib 78 is limited on the front and rear of the shoe by two inclined flanks 79 and 80 which are intended to cooperate with the flanks 75 and 76 of the groove.
Le moyen de verrouillage comprend ici pour la nervure deux éléments 82 et 83 situés vers le milieu des flancs 79 et 80, et fonctionnant à la manière de pênes mobiles dont l'escamotage dans la nervure est commandé par le levier latéral 84.The locking means here comprises for the rib two elements 82 and 83 situated towards the middle of the sides 79 and 80, and operating in the manner of movable bolts, the retraction of which in the rib is controlled by the lateral lever 84.
La nervure présente de son côté, au niveau des flancs inclinés 75 et 76 des logements formant des sortes de gâches dans lesquelles les éléments 82 et 83 sont destinés à s'engager pour maintenir l'élément 11 emboîté sur l'élément 10. Seule la gâche 85 du flanc 76 est visible dans la figure 8.The rib has for its part, at the level of the inclined sides 75 and 76 of the housings forming kinds of strikes in which the elements 82 and 83 are intended to engage to keep the element 11 fitted onto the element 10. Only the keeper 85 of the flank 76 is visible in FIG. 8.
Eventuellement, ainsi que le représente la figure 8, les flancs 75, 76, 79 et 80 de la nervure et de la rainure peuvent présenter des formes complémentaires en creux et en relief 86 à 89 qui sont destinées à améliorer la tenue de l'emboîtement selon les différentes directions, ou bien à empêcher l'emboîtement de l'élément 11 dans un sens qui n'est pas le bon.Optionally, as shown in Figure 8, the sides 75, 76, 79 and 80 of the rib and the groove may have complementary hollow and raised shapes 86 to 89 which are intended to improve the strength of the socket according to the different directions, or else to prevent the nesting of the element 11 in a direction which is not the correct one.
En outre, éventuellement seul l'un des élément 82 ou 83 pourrait être mobile sous la commande du levier 84, l'autre élément étant fixe. Quoiqu'il en soit, de préférence, comme dans le cas précédent, les éléments 82 et 83 et les gâches 85 présentent des rampes destinées à faciliter l'engagement automatique de l'élément 11 sur l'élémentIn addition, possibly only one of the element 82 or 83 could be movable under the control of the lever 84, the other element being fixed. Anyway, preferably, as in the previous case, the elements 82 and 83 and the strikes 85 have ramps intended to facilitate the automatic engagement of the element 11 on the element
10, et le cas échéant à rattraper les jeux entre les deux éléments.10, and if necessary to make up for the clearances between the two elements.
Les figures 9 et 10 représentent une autre variante de mise en oeuvre de l'invention. Selon cette variante, l'élément 11 associé à la chaussure présente une sorte de nervure 90 orientée selon la direction longitudinale de la semelle. La nervure est ici formée par quatre faces 91 , 92, 93, 94, convergeant deux à deux vers la direction longitudinale médiane de la semelle et vers la zone centrale de la semelle , à la manière d'un "X". En outre, selon le mode de réalisation illustré, la nervure 90 est en deux parties 95 et 96 situées vers l'avant et l'arrière de la chaussure. Les deux parties 95 et 96 sont séparées par un evidement, et sont reliées entre elles par un profilé 98, orienté selon la direction longitudinale de la semelle.Figures 9 and 10 show another variant implementation of the invention. According to this variant, the element 11 associated with the shoe has a sort of rib 90 oriented in the longitudinal direction of the sole. The rib is here formed by four faces 91, 92, 93, 94, converging two by two towards the median longitudinal direction of the sole and towards the central zone of the sole, in the manner of an "X". In addition, according to the illustrated embodiment, the rib 90 is in two parts 95 and 96 located towards the front and the rear of the shoe. The two parts 95 and 96 are separated by a recess, and are interconnected by a profile 98, oriented in the longitudinal direction of the sole.
De façon complémentaire, l'élément 10 associé à la planche présente une sorte de rainure 99, orientée selon la direction longitudinale de la chaussure, dont la partie avant et la partie arrière sont évasées. Ces parties avant et arrière sont limitées par quatre flancs 101 à 104. De préférence, ainsi que le représente les figures 9 et 10, la rainure 99 est formée par quatre plots 105 à 108, séparés entre eux par des évidements. Chacun des plots porte un flanc 100 à 103 de la nervure.In a complementary manner, the element 10 associated with the board has a sort of groove 99, oriented in the longitudinal direction of the shoe, the front part and the rear part of which are flared. These front and rear parts are limited by four sides 101 to 104. Preferably, as shown in FIGS. 9 and 10, the groove 99 is formed by four studs 105 to 108, separated from each other by recesses. Each of the studs carries a side 100 to 103 of the rib.
De préférence, les flancs 93 à 96, 101 à 104 sont inclinés de la même façon que dans les cas précédents. L'orientation des flancs par rapport à une direction longitudinale n'est pas limitative, elle est par exemple de l'ordre de 30 à 60 degrés. Cette orientation peut aussi être différente vers l'avant et vers l'arrière de la chaussure. En outre, les figures représentent des flancs plans. Ceci n'est pas limitatif, et les flancs pourraient aussi être incurvés ou bombés.Preferably, the sides 93 to 96, 101 to 104 are inclined in the same way as in the previous cases. The orientation of the sides with respect to a longitudinal direction is not limiting, it is for example of the order of 30 to 60 degrees. This orientation can also be different towards the front and towards the rear of the shoe. In addition, the figures represent flat sides. This is not limiting, and the sides could also be curved or curved.
Au milieu des plots 105, 107 et 103, 104, dans le sens longitudinal, l'élément 10 présente un moyen de verrouillage qui est destiné à coopérer avec le profil 98 de l'élément 11.In the middle of the studs 105, 107 and 103, 104, in the longitudinal direction, the element 10 has a locking means which is intended to cooperate with the profile 98 of the element 11.
Dans l'exemple illustré, le moyen de verrouillage comprend une targette 110 , guidée au coulissement selon une direction transversale par un support transversal 111. La targette 110 peut être manoeuvrée à l'ouverture par une tirette 112 qui constitue son prolongement au delà du supportIn the example illustrated, the locking means comprises a bolt 110, guided in sliding in a transverse direction by a transverse support 111. The bolt 110 can be operated at the opening by a pull tab 112 which constitutes its extension beyond the support
11. Comme dans le cas précédent, un moyen élastique tel qu'un ressort peut assurer la fermeture automatique de la targette.11. As in the previous case, an elastic means such as a spring can ensure the automatic closing of the bolt.
De préférence, un second support 113 fait face au premier. Les deux supports forment entre eux un evidement 115 destiné à recevoir le profilé 98. Eventuellement, l'évidement 115 est évasé vers le haut. De plus, la targette peut présenter une rampe supérieure destinée à faciliter l'engagement automatique du profilé, et une rampe inférieure destinée à rattraper les jeux à ce niveau.Preferably, a second support 113 faces the first. The two supports form between them a recess 115 intended to receive the profile 98. Optionally, the recess 115 is flared upwards. In addition, the targette may have an upper ramp intended to facilitate the automatic engagement of the profile, and a lower ramp intended to make up for play at this level.
Selon la présente variante, le moyen de verrouillage n'agit sur l'élément associé à la chaussure que selon une direction verticale, vers le haut. Les autres degrés de liberté entre les deux éléments 10 et 11 en rotation ou en translation sont neutralisés par la coopération des flancs de la rainure et de la nervure.According to the present variant, the locking means acts on the element associated with the shoe only in a vertical direction, upwards. The other degrees of freedom between the two elements 10 and 11 in rotation or in translation are neutralized by the cooperation of the sides of the groove and of the rib.
Au sujet de cette variante, il faut aussi souligner que la distinction entre nervure et rainure devient très floue. En effet, l'élément associé à la planche pourrait aussi être considéré comme présentant une nervure transversale formée par les plots 105 à 108, et l'élément associé à la chaussure comme présentant une nervure orientée transversalement. L'invention doit donc être comprise de façon générale comme la coopération de deux formes complémentaires, ces formes neutralisant par leur coopération au moins une partie des mouvements relatifs entre les deux éléments du dispositif, l'autre partie étant neutralisée par le moyen de verrouillage.Regarding this variant, it should also be noted that the distinction between rib and groove becomes very blurred. Indeed, the element associated with the board could also be considered as having a transverse rib formed by the studs 105 to 108, and the element associated with the shoe as having a transversely oriented rib. The invention must therefore be understood in general as the cooperation of two complementary forms, these forms neutralizing by their cooperation at least part of the relative movements between the two elements of the device, the other part being neutralized by the locking means.
De préférence, les formes complémentaires neutralisent la rotation de la chaussure par rapport à la planche au moins autour d'un axe vertical, c'est à dire orthogonal à la planche.Preferably, the complementary shapes neutralize the rotation of the shoe relative to the board at least about a vertical axis, that is to say orthogonal to the board.
Les dimensions des formes qui coopèrent par emboîtement ne sont pas limitatives. De préférence, elles s'inscrivent dans le contour de la semelle de chaussure et de sa projection sur la planche. Il n'y a pas de relation directe entre la longueur d'une chaussure et les dimensions longitudinales des formes, si bien que l'élément associé à la planche peut être utilisé sans modification ni réglage avec des chaussures de longueur différente ou de volume différent. Il suffit de prévoir sur ces différentes chaussures la même forme complémentaire et les mêmes emplacements pour le moyen d'accrochage et le moyen de verrouillage. De préférence, au niveau de la chaussure, la nervure ou la rainure s'étend depuis la zone des métatarses jusque la zone du talon. Ainsi, pour une gamme définie de longueurs de chaussures, les formes complémentaires des éléments associés à la planche et à la chaussure s'étendent depuis la zone des métatarses jusqu'au talon du pied de plus grande longueur. Toutefois, ceci n'est pas limitatif vis à vis de l'invention.The dimensions of the forms which cooperate by interlocking are not limiting. Preferably, they are part of the outline of the shoe sole and of its projection on the board. There is no direct relation between the length of a shoe and the longitudinal dimensions of the forms, so that the element associated with the board can be used without modification or adjustment with shoes of different length or of different volume. . It suffices to provide on these different shoes the same complementary shape and the same locations for the fastening means and the locking means. Preferably, at the level of the shoe, the rib or the groove extends from the area of the metatarsals to the area of the heel. Thus, for a defined range of shoe lengths, the complementary shapes of the elements associated with the board and the shoe extend from the metatarsal area to the heel of the longer foot. However, this is not limiting with respect to the invention.
Les éléments 10 et 12 associés à la planche de glisse et à la chaussure sont réalisés en tout matériau approprié. Par exemple, ils sont réalisés en une matière plastique ou un alliage léger.The elements 10 and 12 associated with the gliding board and the boot are made of any suitable material. For example, they are made of a plastic material or a light alloy.
Naturellement la présente description n'est donnée qu'à titre indicatif, et l'on pourrait adopter d'autres mises en oeuvre de l'invention sans pour autant sortir du cadre de celle-ci.Of course, this description is given for information only, and other implementations of the invention could be adopted without departing from the scope thereof.
En particulier, l'élément associé à la planche pourrait être en outre équipé de tout moyen approprié pour régler son orientation dans le plan horizontal par rapport à l'axe 2 de la planche, et de tout autre moyen approprié pour régler le cas échéant son inclinaison par rapport à une direction perpendiculaire à la surface de la planche, ainsi que sa position longitudinale sur la planche.In particular, the element associated with the board could also be equipped with any suitable means for adjusting its orientation in the horizontal plane relative to the axis 2 of the board, and with any other suitable means for adjusting its tilt relative to a direction perpendicular to the surface of the board, as well as its longitudinal position on the board.
De plus, il va de soi que l'invention concerne toute chaussure destinée à la pratique du surf de neige quelque soit son type, qui serait équipée d'un élément de retenue du genre associé à la chaussure.In addition, it goes without saying that the invention relates to any shoe intended for the practice of snowboarding whatever its type, which would be equipped with a retaining element of the kind associated with the shoe.
Egalement, il va de soi que l'invention concerne aussi toute plaque intermédiaire qui serait utilisée comme interface entre une chaussure traditionnelle et une planche de glisse équipée d'un élément de retenue d'un genre qui vient d'être décrit. Dans ce cas, la plaque intermédiaire serait équipée d'un élément de retenue complémentaire du genre associé à la chaussure.Also, it goes without saying that the invention also relates to any intermediate plate which would be used as an interface between a traditional boot and a gliding board equipped with a retaining element of a kind which has just been described. In this case, the intermediate plate would be equipped with a complementary retaining element of the kind associated with the shoe.
Il va de soi aussi que l'invention couvre aussi une planche de glisse qui serait équipée d'un élément de retenue intégré à sa structure, ou rapporté, du genre associé à la planche de glisse. It goes without saying also that the invention also covers a gliding board which would be equipped with a retaining element integrated into its structure, or attached, of the kind associated with the gliding board.
