Description

La présente invention concerne une fixation d'une chaussure sur un surf à neige, et plus particulièrement un dispositif de fixation qui comporte des éléments destinés à maintenir les extrémités avant et arrière d'une chaussure.The present invention relates to a binding of a shoe on a snowboard, and more particularly to a binding device which comprises elements intended to hold the front and rear ends of a shoe.

Au début de la pratique du surf à neige, les fixations étaient montées à plat sur le surf et perpendiculairement à celui-ci. Il est progressivement apparu que les performances pouvaient être améliorées en modifiant la position de la fixation, par exemple en réduisant l'angle formé par l'axe de la fixation et l'axe longitudinal du surf, ainsi qu'en modifiant l'angle formé par la jambe et la surface du surf, ceci latéralement et frontalement. En pratique, il est donc devenu important que chaque surfeur puisse modifier ces différents paramètres en fonction de sa morphologie, de son niveau et des conditions d'utilisation. Pour les spécialistes qui louent les surfs à neige, il est par conséquent devenu essentiel que ces différents réglages puissent être effectués facilement et rapidement.At the start of snowboarding, the bindings were mounted flat on the board and perpendicular to it. It gradually appeared that the performances could be improved by modifying the position of the binding, for example by reducing the angle formed by the axis of the binding and the longitudinal axis of the surf, as well as by modifying the angle formed. by the leg and the surface of the surf, this laterally and frontally. In practice, it has therefore become important that each surfer can modify these different parameters according to his morphology, level and conditions of use. For specialists who rent snowboards, it has therefore become essential that these various adjustments can be made quickly and easily.

On connaît déjà des réalisations de fixations de surf à neige qui comportent des dispositifs de réglage, mais elles présentent toutefois toutes de nombreux inconvénients. En effet, ces dispositifs sont réalisés notamment avec des mécanismes compliqués qui présentent les désavantages d'être peu pratiques à utiliser et d'être d'un poids élevé. De plus, ces dispositifs connus sont d'un prix de revient élevé, ce qui a contribué à freiner leur commercialisation auprès des jeunes surfeurs qui constituent la majorité des surfeurs.There are already known embodiments of snowboard bindings which include adjustment devices, but they all have many drawbacks, however. Indeed, these devices are made in particular with complicated mechanisms which have the disadvantages of being impractical to use and of being heavy. In addition, these known devices are of a high cost price, which has helped to slow their marketing to young surfers who constitute the majority of surfers.

Le but de la présente invention consiste donc à remédier aux inconvénients des fixations connues pour surf à neige, et à fournir une fixation dont les dispositifs de réglages sont combinés de manière à permettre le réglage de plusieurs paramètres, et ceci de manière beaucoup plus pratique et rapide à effectuer, et qui soit d'un poids réduit et d'un faible prix de revient.The object of the present invention therefore consists in remedying the drawbacks of known bindings for snowboarding, and in providing a binding whose adjustment devices are combined so as to allow the adjustment of several parameters, and this in a much more practical manner and quick to perform, and which is of reduced weight and low cost.

Le dispositif de fixation selon l'invention qui vise à atteindre le but précité présente les caractéristiques définies dans la revendication 1.The fixing device according to the invention which aims to achieve the above object has the characteristics defined in claim 1.

L'invention sera maintenant décrite plus en détails en référence aux dessins annexés qui illustrent schématiquement et à titre d'exemple le dispositif de fixation selon l'invention.The invention will now be described in more detail with reference to the accompanying drawings which illustrate schematically and by way of example the fixing device according to the invention.

  • Les figures 8 et 9 sont des vues respectivement de côté et en plan d'une troisième forme d'exécution du dispositif de fixation selon l'invention.Figures 8 and 9 are respectively side and plan views of a third embodiment of the fixing device according to the invention.
  • Les figures 10 à 12 sont des vues respectivement de côté, en coupe et de l'arrière de détails du dispositif des figures 8 et 9.FIGS. 10 to 12 are respectively side, sectional and rear views of details of the device in FIGS. 8 and 9.
  • Les figures 13 et 14 sont des vues respectivement de côté partiellement en coupe longitudinale et en coupe transversale d une quatrième forme d'exécution du dispositif de fixation.Figures 13 and 14 are respectively side views partially in longitudinal section and in cross section of a fourth embodiment of the fixing device.

En référence tout d'abord aux figures 1 à 3, le dispositif de fixation illustré comporte deux tubes 1,1' fixés dans l'alignement l'un de l'autre dans un boîtier central 2, au moyen d'éléments de fixation 3,3'. Des organes d'accrochage ou de maintien 4,4' sont montés sur les portions d'extrémités libres des tubes 1,1', de manière déplaçable longitudinalement pour permettre d'ajuster leur position respective; ces organes 4,4' comportent des vis de blocage 5,5' pour les maintenir sur les tubes 1,1' dans la position choisie, et sont munis de brides 6,7 pour la fixation des extrémités respectivement postérieure et antérieure d une chaussure de ski (non illustrée), le blocage de celle-ci étant assuré par un levier de verrouillage 8 articulé sur la bride avant 7, ceci de manière connue en soi.Referring first to Figures 1 to 3, the illustrated fixing device comprises two tubes 1,1 'fixed in alignment with each other in a central housing 2, by means of fixing elements 3 , 3 '. 4,4 'hooking or holding members are mounted on the free end portions of the tubes 1,1', longitudinally displaceable to allow their respective positions to be adjusted; these 4.4 'organs include locking screws 5.5' to hold them on the tubes 1.1 'in the chosen position, and are provided with flanges 6.7 for fixing the respectively rear and anterior ends of a shoe ski (not shown), the blocking thereof being ensured by a locking lever 8 articulated on the front flange 7, this in a manner known per se.

Le boîtier central 2, et par là les tubes 1,1' et les organes d'accrochage 4,4' avec brides 6,7, est monté sur une plaque de pivotement ou platine 9, elle-même fixée sur la surface supérieure d'un surf à neige SN. Plus particulièrement, ledit boîtier 2 est monté pivotant autour d'un axe vertical constitué ici par un boulon de blocage 10, celui-ci coopérant avec un élément cylindrique 11 avec taraudage interne, cet élément étant solidaire de la platine 9. D'autre part, un garnissage antidérapant, formé ici de deux rondelles en caoutchouc superposées 12,12' ayant chacune une épaisseur diamétralement décroissante, est intercalé entre le boîtier central 2 et la plaque de pivotement 9.The central box 2, and thereby the tubes 1,1 'and the hooking members 4,4' with flanges 6,7, is mounted on a pivoting plate or plate 9, itself fixed on the upper surface d '' SN snowboard. More particularly, said housing 2 is pivotally mounted about a vertical axis here constituted by a locking bolt 10, the latter cooperating with a cylindrical element 11 with internal thread, this element being integral with the plate 9. On the other hand , a non-slip lining, here formed of two superimposed rubber washers 12,12 'each having a diametrically decreasing thickness, is interposed between the central housing 2 and the pivot plate 9.

Ainsi, le réglage de l'angle de la fixation par rapport à l'axe longitudinal du surf peut être effectué en faisant pivoter le boiter central 2, et par là les tubes de support 1,1', sur la platine 9, la vis de blocage 10 étant desserrée. En position de service, la fixation est donc maintenue, dans la position choisie, par le serrage de la vis 10 et grâce à la présence, entre la platine 9 et la surface inférieure du boîtier central 2, des rondelles antidérapantes 12,12'. En principe, l'angle entre la fixation et par là la chaussure de ski, et l'axe longitudinal du surf est compris entre 90 et un angle aigu de préférence supérieur à 30°, les fixations destinées aux deux chaussures n étant pas forcément parallèles l'une à l'autre sur la surface supérieure du surf.Thus, the adjustment of the angle of the fixing relative to the longitudinal axis of the surf can be carried out by rotating the central box 2, and thereby the support tubes 1,1 ', on the plate 9, the screw 10 being released. In the operating position, the fastening is therefore maintained, in the chosen position, by tightening the screw 10 and thanks to the presence, between the plate 9 and the lower surface of the central housing 2, of the non-slip washers 12, 12 ′. In principle, the angle between the binding and thereby the ski boot, and the longitudinal axis of the board is between 90 and an acute angle preferably greater than 30 °, the bindings intended for the two boots are not necessarily parallel one at the other on the upper surface of the surf.

D'autre part, le déplacement longitudinal des organes d accrochage 4,4' sur les tubes respectifs 1,1' permet d'obtenir un réglage de la longueur en fonction de la pointure de la chaussure de ski. Enfin, ces organes d accrochage 4,4' peuvent encore être déplacés par pivotement autour des tubes 1,1', afin de régler le plan des chaussures par rapport à celui du surf, c'est-à-dire l'angle latéral que forme la chaussure et donc la jambe du surfeur avec la surface du surf.On the other hand, the longitudinal movement of the fastening members 4,4 'on the respective tubes 1,1' makes it possible to obtain an adjustment of the length as a function of the size of the ski boot. Finally, these fastening members 4,4 ′ can also be moved by pivoting around the tubes 1,1 ′, in order to adjust the plane of the boots relative to that of the surf, that is to say the lateral angle that forms the shoe and therefore the surfer's leg with the surface of the surf.

La seconde forme d'exécution de la fixation selon l'invention illustrée schématiquement sur les figures 4 à 7 se distingue de celle qui vient d'être décrite en référence aux figures 1 à 3 par le fait qu'elle ne comporte qu'un seul tube de support 21 enrobé de fabrication par vulcanisation dans un bloc d'élastomère 22, servant de boîtier central; de plus une plaque de préférence métallique 23 est également vulcanisée à la surface inférieure de ce bloc d'élastomère 22. Les autres éléments constitutifs de la fixation sont les mêmes que ceux de la première forme d'exécution et sont désignés sur les figures 3 à 7 par les mêmes chiffres de référence.The second embodiment of the binding according to the invention illustrated schematically in Figures 4 to 7 differs from that which has just been described with reference to Figures 1 to 3 by the fact that it comprises only one support tube 21 coated with vulcanization manufacturing in an elastomer block 22, serving as a central housing; in addition, a preferably metallic plate 23 is also vulcanized on the lower surface of this block of elastomer 22. The other constituent elements of the binding are the same as those of the first embodiment and are designated in FIGS. 3 to 7 by the same reference figures.

Comme représenté sur les figures 5 et 6, on peut également prévoir selon une variante une ouverture allongée 24 dans la platine 25, cette dernière présentant une forme de préférence ovale, ainsi que dans la rondelle antidérapante 26. Cette ouverture 24 permet un réglage supplémentaire par déplacement du boîtier central 22 perpendiculairement à l'axe du tube support 21, c'est-à-dire un réglage de l'entraxe entre les deux fixations du surf.As shown in FIGS. 5 and 6, an elongated opening 24 can also be provided in a variant 24 in the plate 25, the latter having a preferably oval shape, as well as in the non-slip washer 26. This opening 24 allows additional adjustment by displacement of the central housing 22 perpendicular to the axis of the support tube 21, that is to say an adjustment of the distance between the two fastenings of the surf.

Enfin, cette fixation peut encore comporter des tiges de renforcement 27, incorporées de fabrication dans le bloc d'élastomère 22, afin de rigidifier celui-ci en tension de manière plus importante d'un côté que de l'autre par exemple.Finally, this attachment may also include reinforcing rods 27, incorporated during manufacture in the elastomer block 22, in order to stiffen the latter in tension more on one side than on the other for example.

Les tubes supports 1,1' ou 21 de la fixation selon l'invention sont de préférence de section circulaire; ils peuvent également être de section carrée ou rectangulaire, ou autre; toutefois, dans ce cas, le réglage de l'angle latéral n'est plus possible, puisque les organes d'accrochage 4,4' ne peuvent être déplacés qu'axialement sur ledit tube et non en rotation autour de celui-ci.The support tubes 1,1 ′ or 21 of the binding according to the invention are preferably of circular section; they can also be of square or rectangular section, or other; however, in this case, the adjustment of the lateral angle is no longer possible, since the hooking members 4,4 ′ can only be moved axially on said tube and not in rotation around it.

La forme des brides, ainsi que les dispositifs d'accrochage liés aux brides pour maintenir les parties avant et arrière de la chaussure sont indépendants du principe de l'invention. Il existe en effet de très nombreuses formes d'exécutions connues de brides qui peuvent toutes être facilement adaptées sur la fixation selon l'invention.The shape of the straps, as well as the attachment devices linked to the straps to hold the front and rear parts of the shoe, are independent of the principle of the invention. There are indeed many forms of known designs of flanges which can all be easily adapted on the fastener according to the invention.

Les matériaux utilisés pour la réalisation des différents éléments de la fixation sont également indépendants du principe de l'invention, et à titre d exemple ces éléments peuvent être réalisés en métaux ferreux ou non ferreux, en matériaux composites, ou en matières plastiques.The materials used for the production of the various elements of the binding are also independent of the principle of the invention, and by way of example these elements can be made of ferrous or non-ferrous metals, of composite materials, or of plastics.

Quant au bloc en élastomère servant de boîtier central, il peut être réalisé, par exemple, en un polymère styrène-butadiène, et de toute façon avec un matériau qui ne soit pas trop sensible aux écarts de températures, notamment en ce qui concerne ses propriétés élastiques. Ces propriétés élastiques permettent en effet de conférer une certaine "souplesse" à la fixation, ce qui est recherché par les utilisateurs, et surtout des caractéristiques améliorées d'absorption des chocs qui rend son utilisation plus agréable.As for the elastomer block serving as a central housing, it can be made, for example, of a styrene-butadiene polymer, and in any case with a material which is not too sensitive to temperature variations, in particular as regards its properties elastic. These elastic properties indeed make it possible to impart a certain "flexibility" to the binding, which is sought after by users, and above all improved shock absorption characteristics which make its use more pleasant.

En référence maintenant aux figures 8 et 9, la fixation selon une troisième réalisation comporte un tube 31 qui est monté dans un boîtier central 46. Ce boîtier central 46 est monté sur des éléments profilés 32 qui sont fixés sur une plaque de rotation 33 par des vis 38,38' et 38". Des éléments 39 et 40 sont montés sur chacune des extrémités du tube 31. Des brides 43,44 sont fixées respectivement sur les éléments 39 et 40 et sont destinées à maintenir respectivement les parties avant et arrière d une chaussure. La plaque de rotation 33 est maintenue par un anneau 34 qui est fixé sur un surf 35 par des vis 45. La plaque de rotation 33 et l'anneau 34 comportent des rainures 48 qui sont destinées à collaborer entre elles. L'angle de fixation par rapport au surf est réglable par rotation de la plaque de rotation 33 dans l'anneau 34. En position de service, les vis 45 sont serrées et maintiennent la fixation dans la position choisie, la fixation étant bloquée dans cette position par les rainures 48. Le réglage d'angle de la fixation par rapport à l'axe longitudinal du surf s'effectue en désserrant les vis 45, ce qui permet la rotation de la plaque de rotation 33. Le boîtier central 46 est fixé sur les éléments profilés 32 par des vis 36 et 37 avec des écrous 49 et 50. Les vis 36 et 37 et les écrous 49 et 50 permettent, lorsqu'ils sont serrés de maintenir le boîtier central en position de service. En position de réglage, qui est obtenue par le désserrage des écrous 49 et 50, le boîtier central 46 pivote sur la vis 36 et la vis 37 peut se déplacer dans l'ouverture 47 pratiquée dans chacun des éléments profilés 32. Le pivotement du boîtier central sur la vis 36 permet le réglage de l'angle frontal de la fixation. Lorsque la position de l'angle frontal choisi est obtenue, les écrous sont resserrés pour maintenir le boîtier central et par conséquent la fixation en position de service. Les éléments 39 et 40, qui comportent les brides 43 et 44, sont montés sur le tube 31 et maintenus en position de service par des vis 41 et 42, le serrage des vis permettant de bloquer les éléments 39 et 40. Le désserrage des vis 41 et 42 permet le déplacement des éléments 39 et 40 sur le tube 31. Le déplacement longitudinal des éléments 39 et 40 sur le tube permet d'obtenir le réglage de longueur, c'est-à-dire le réglage qui permet d'ajuster la fixation en fonction des différentes pointures de chaussures, donc des différentes longueurs de semelles de chaussures. Dans cette position de réglage, les éléments 39 et 40 peuvent pivoter sur le tube 31, ce qui permet de modifier l'angle latéral, c'est-à-dire l'angle que forme la chaussure et donc la jambe du surfeur par rapport à la surface du surf.Referring now to Figures 8 and 9, the attachment according to a third embodiment comprises a tube 31 which is mounted in a central housing 46. This central housing 46 is mounted on profiled elements 32 which are fixed to a rotation plate 33 by screws 38,38 'and 38 ". Elements 39 and 40 are mounted on each end of the tube 31. Flanges 43,44 are fixed respectively on elements 39 and 40 and are intended to hold the front and rear parts respectively a shoe The rotation plate 33 is held by a ring 34 which is fixed to a surface 35 by screws 45. The rotation plate 33 and the ring 34 have grooves 48 which are intended to collaborate with each other. fixing angle with respect to the surf is adjustable by rotation of the rotation plate 33 in the ring 34. In the service position, the screws 45 are tightened and hold the fixing in the chosen position, the fixing being blocked d In this position by the grooves 48. The angle of the binding is adjusted relative to the longitudinal axis of the surf by loosening the screws 45, which allows the rotation of the rotation plate 33. The central housing 46 is fixed to the profiled elements 32 by screws 36 and 37 with nuts 49 and 50. The screws 36 and 37 and the nuts 49 and 50 make it possible, when tightened, to keep the central housing in the service position. In the adjustment position, which is obtained by loosening the nuts 49 and 50, the central housing 46 pivots on the screw 36 and the screw 37 can move in the opening 47 made in each of the profiled elements 32. The pivoting of the housing central on screw 36 allows adjustment of the front angle of the binding. When the position of the chosen front angle is obtained, the nuts are tightened to keep the central box and consequently the fixing in the service position. The elements 39 and 40, which include the flanges 43 and 44, are mounted on the tube 31 and held in the service position by screws 41 and 42, the tightening of the screws making it possible to block the elements 39 and 40. The loosening of the screws 41 and 42 allows the displacement of the elements 39 and 40 on the tube 31. The longitudinal displacement of the elements 39 and 40 on the tube makes it possible to obtain the length adjustment, that is to say the adjustment which makes it possible to adjust the binding according to the different shoe sizes, therefore the different lengths of the soles shoes. In this adjustment position, the elements 39 and 40 can pivot on the tube 31, which makes it possible to modify the lateral angle, that is to say the angle formed by the boot and therefore the leg of the surfer relative to on the surface of the surf.

La figure 10 montre la fixation avec une position à fort angle frontal. Pour obtenir cette position, l'écrou 49 de la vis 36 a été desséré afin de permettre le pivotement du boîtier central, donc du tube 31, sur la vis 37 qui collabore avec l'écrou 50, la vis 37 se déplaçant dans l'ouverture 47.Figure 10 shows the binding with a position with a large frontal angle. To obtain this position, the nut 49 of the screw 36 has been loosened in order to allow the pivoting of the central housing, therefore of the tube 31, on the screw 37 which collaborates with the nut 50, the screw 37 moving in the opening 47.

La figure 11 montre une vue de détail du boîtier 46 et des éléments profilés 32 et 32', avec une des vis 7 collaborant avec un des écrous 20. Enfin, la figure 12 illustre un des éléments à bride 39 qui est constitué de deux éléments, qui sont assemblés entre eux par le serrage des vis 41 et 41', serrage qui provoque également le blocage de l'élément 39 sur le tube 31, en position de service. Cette figure 12 montre la fixation avec un fort angle latéral.FIG. 11 shows a detailed view of the housing 46 and of the profiled elements 32 and 32 ′, with one of the screws 7 collaborating with one of the nuts 20. Finally, FIG. 12 illustrates one of the flange elements 39 which consists of two elements , which are assembled together by tightening the screws 41 and 41 ', tightening which also causes the blocking of the element 39 on the tube 31, in the service position. This figure 12 shows the fixing with a strong lateral angle.

Les matériaux utilisés pour la réalisation des différents éléments de la fixation telle que décrits en référence aux figures 8 à 12 sont également indépendants du principe de l'invention, et à titre d'exemple ces éléments peuvent être réalisés en métaux ferreux ou non ferreux, en matières composites, ou en matières plastiques.The materials used for the production of the various elements of the binding as described with reference to FIGS. 8 to 12 are also independent of the principle of the invention, and by way of example these elements can be made of ferrous or non-ferrous metals, in composite materials, or in plastics.

Le principal avantage de la fixation selon l'invention réside dans ses nombreuses possibilités de réglages aisés et rapides, ce qui est très important surtout pour les loueurs de surfs à neige. En effet, cette fixation permet de modifier la longueur, l'angle de position sur le surf par rapport à l'axe longitudinal de celui-ci et l'angle latéral, ainsi que l'entraxe entre les deux fixations du surf. Ainsi, cette fixation peut être réglée facilement et rapidement non seulement en fonction de la pointure des chaussures de ski, mais également de la position particulière souhaitée pour chaque utilisateur. Elle est de plus d'un prix de revient relativement plus faible que les fixations connues.The main advantage of the binding according to the invention lies in its numerous possibilities for easy and rapid adjustment, which is very important especially for the snowboard rental companies.
