Abstract

The snowboard is provided with a central cavity (102) defining two longitudinal side beams (103,104). Anchoring points (107,108) are arranged in these side beams in which an intermediate plate (106) for the front and rear feet is fixed (107,108). The intermediate plate is provided in its central support zone overhanging the cavity with anchoring means (109) for fixing the corresponding boot.

Description

La présente invention se rapporte à un ensemble de glisse sur neige, comprenant un surf des neiges et un système de réception des chaussures du surfeur.The present invention relates to a set of sliding on snow, including a snowboard and a shoe receiving system surfer.

La planche de glisse que constitue le surf de neige est utilisée de manière asymétrique, l'utilisateur n'ayant ni le corps, ni les pieds, dirigés selon l'axe longitudinal de la planche, mais placés fortement en biais par rapport à celui-ci. Le corps du surfeur est placé de travers par rapport à sa planche avec soit, pour les personnes à pied directeur droit (« regular foot »), le pied droit en arrière et le pied gauche en avant, soit, pour les personnes à pied directeur gauche (« goofy foot »), le pied gauche en arrière et le pied droit en avant. L'écartement des pieds dépend de la morphologie de l'utilisateur, et essentiellement de sa taille. Les pointes de pied sont plus ou moins tournées vers l'avant du surf, cette orientation étant indiquée par un angle mesuré à partir de la perpendiculaire à l'axe longitudinal du surf. Cette orientation peut généralement varier, pour le pied arrière, entre 0 et 40 degrés environ et, pour le pied avant, entre 10 et 45 degrés, la position la plus en faveur aujourd'hui auprès de nombreux surfeurs de bon niveau étant la position dite intermédiaire :

  • pied arrière : angle d'orientation compris entre 10 et 15 degrés,
  • pied avant : angle d'orientation compris entre 30 et 45 degrés.
The snowboard that constitutes snowboarding is used asymmetrically, the user having neither the body nor the feet, directed along the longitudinal axis of the board, but placed strongly at an angle relative to it. this. The surfer's body is placed askew with respect to his board with either, for people with right foot ("regular foot"), right foot back and left foot forward, or, for people with foot left ("goofy foot"), left foot back and right foot forward. The spacing of the feet depends on the morphology of the user, and essentially on his size. The toes are more or less turned towards the front of the board, this orientation being indicated by an angle measured from the perpendicular to the longitudinal axis of the board. This orientation can generally vary, for the rear foot, between 0 and 40 degrees approximately and, for the front foot, between 10 and 45 degrees, the position most in favor today with many good surfers being the so-called position intermediate:
  • rear leg: angle of orientation between 10 and 15 degrees,
  • front foot: angle of orientation between 30 and 45 degrees.

Quoi qu'il en soit, le surfeur a son corps de travers par rapport à l'engin et à la direction de son déplacement. Les virages se prennent soit en penchant le corps vers l'avant, en direction des pointes de pied (on dit plus simplement côtés pointes ou «front-side»), soit en penchant le corps vers l'arrière, en direction des talons (ou « back-side »).Anyway, the surfer has his body askew in relation to the craft and the direction of its movement. The turns are taken either in leaning the body forward, towards the tips of the feet (we say more simply pointed sides or "front-side"), either by leaning the body towards the back, towards the heels (or "back-side").

Le surf de neige fait aujourd'hui l'objet d'un engouement exceptionnel, surtout auprès d'un public jeune, de sorte que des compétitions de surf sont maintenant organisées à l'instar des compétitions de ski, et le facteur « vitesse » devient essentiel pour les surfs destinés à ces compétitions, ainsi que bien entendu la capacité de ces surfs à effectuer des virages avec une précision maximale.Snowboarding is the subject of a craze today exceptional, especially with a young audience, so that competitions surf are now organized like ski competitions, and the factor "Speed" becomes essential for the surfs intended for these competitions, as well as of course the ability of these surfboards to make turns with precision Max.

Cet engouement pour le surf de neige gagne aussi d'autres personnes que les personnes très jeunes, de sorte qu'il devient en outre nécessaire de prévoir d'une part des surfs pour dames, présentant de grandes qualités de légèreté et de confort, ainsi que d'autre part des surfs « grand public » présentant de bonnes qualités de confort sans toutefois trop pénaliser l'efficacité et la légèreté.This snowboarding craze is also winning over other people than very young people, so it also becomes necessary to plan on the one hand, women's surfboards, with great qualities of lightness and comfort, as well as "general public" surfboards with good comfort qualities without however penalizing efficiency and lightness.

D'une manière générale, la planche de glisse que constitue un surf de neige doit être suffisamment raide, en flexion à plat, pour s'enfoncer le moins possible dans la neige et donc glisser avec une vitesse maximale sans pour autant être trop raide afin d'inscrire la ligne de carres dans une courbe lors de l'exécution d'un virage.In general, the gliding board that constitutes a surf of snow must be stiff enough, in flat bending, to sink the least possible in snow and therefore slide with maximum speed without necessarily be too steep in order to register the edge line in a curve during execution of a turn.

Il faut donc que cette planche soit le plus raide possible lorsqu'elle est à plat, et le plus souple possible en flexion inclinée, c'est à dire lorsqu'elle est inclinée en reposant sur sa carre.This board must therefore be as stiff as possible when it is flat, and as flexible as possible in inclined bending, that is to say when it is tilted while resting on its square.

Ces deux conditions sont contradictoires, et toute la science des fabriquants de planches de glisse pour surfs de neige consiste à trouver le bon compromis raideur/souplesse qui permette à la fois de se déplacer rapidement à plat tout en ayant une facilité et une précision optimales lors de l'exécution d'un virage.These two conditions are contradictory, and the whole science of manufacturers of boards for snowboards is to find the right one stiffness / flexibility compromise that allows both to move quickly at flat while having optimum ease and precision when performing a turn.

Un problème supplémentaire réside dans le fait que, la planche que constitue ce surf étant relativement large, elle est généralement assez lourde, ce qui est ennuyeux.An additional problem is that the plank that this surf being relatively wide, it is generally quite heavy, this which is boring.

Un autre paramètre important à gérer est la raideur latérale de la planche, c'est à dire celle qui s'exerce sur le surf lorsque l'on pose celui-ci à plat sur un marbre horizontal, en appliquant alors à ce surf, en son point médian, une force dirigée latéralement. En effet, pour permettre une bonne précision de trajectoire, il est important que le surf soit très raide latéralement pour ne pas modifier la forme de la ligne de cotes, c'est à dire : la forme de la courbe qui suit l'arête de chaque carre.Another important parameter to manage is the lateral stiffness of the board, that is to say the one that is exerted on the surf when you put it flat on a horizontal marble, then applying to this surf, at its midpoint, a force directed laterally. Indeed, to allow a good precision of trajectory, it is important that the surf is very steep laterally so as not to modify the shape of the dimension line, i.e. the shape of the curve that follows the edge of each square.

EP-A-0 848 968 divulgue ce type de surf de neige avec une flexibilité transversale accrue. EP-A-0 848 968 discloses this type of snowboard with increased transverse flexibility.

Un premier but de l'invention est de concilier tous ces impératifs et d'obtenir en particulier un ensemble de glisse sur neige incorporant un surf constitué par une planche légère, raide en flexion à plat et en flexion latérale, moins raide en flexion inclinée, et cependant très nerveuse.A first object of the invention is to reconcile all these imperatives and to obtain in particular a set of gliding on snow incorporating a surf constituted by a light board, stiff in flat bending and in lateral bending, less stiff in inclined flexion, and yet very nervous.

Les systèmes de blocage des pieds sur une planche de glisse sur neige, tel qu'un surf, sont actuellement appelés « fixations ». Ils viennent se fixer sur le surf au moyen d'orifices qui sont pratiqués dans la zone centrale de chaque fixation et dans la zone centrale du surf.Foot locking systems on a snow gliding board, such as a surfboard, are currently called "bindings". They come to settle on the surf by means of holes which are practiced in the central zone of each binding and in the central area of the surf.

La position des orifices de liaison de la fixation au surf est aujourd'hui suffisamment généralisée pour être considérée comme standardisée sous deux configurations géométriques :

  • Le perçage dit « 4x4 » qui est le plus répandu et qui est matérialisé par deux zones (une pour chaque pied) de huit trous chacune, ces trous étant espacés de 40 millimètres l'un de l'autre et étant répartis selon deux colonnes parallèles de quatre trous chacune. Ces huit trous sont généralement percés et taraudés à l'avance sur le surf.
  • Le perçage triangulaire, dit « 3D » selon la marque déposée par la Société BURTON, et existant sur les surfs et les fixations de cette Société.
The position of the connection holes of the surfboard binding is today generalized enough to be considered as standardized in two geometric configurations:
  • The most widely used “4x4” bore, which is materialized by two zones (one for each foot) of eight holes each, these holes being spaced 40 millimeters apart and being distributed in two parallel columns of four holes each. These eight holes are usually drilled and tapped in advance on the surf.
  • The triangular drilling, called "3D" according to the brand registered by the BURTON Company, and existing on the surfboards and the fixings of this Company.

Ces fixations actuelles ne peuvent pas être rapportées telles qu'elles sur un surf de neige ne présentant pas la possibilité de loger un taraudage, par manque d'épaisseur, à l'endroit où elles doivent être fixées, en particulier sur un surf présentant un évidement longitudinal dans la zone médiane. Un autre but de la présente invention est de remédier à cet inconvénient.These current fixings cannot be brought back as they are. on a snowboard that does not have the possibility of accommodating a thread, for lack of thickness, at the place where they must be fixed, in particular on a surf with a longitudinal recess in the middle zone. Another purpose of the present invention is to remedy this drawback.

Par ailleurs, il est connu qu'un surf de neige est rigidifié dans le sens transversal aussi bien par les fixations que par les pieds du surfeur, qui sont tous positionnés en travers de la planche. Un autre but de l'invention est de déconnecter l'incidence des pieds du surfeur sur la raideur transversale du surf, et plus généralement d'éviter de brider le surf dans le sens transversal. Furthermore, it is known that a snowboard is stiffened in the direction transverse as well by the bindings as by the feet of the surfer, which are all positioned across the board. Another object of the invention is to disconnect the incidence of the surfer's feet on the transverse stiffness of the surf, and more generally to avoid clamping the surf crosswise.

Un autre but de l'invention est de permettre en outre différents réglages de la position des pieds du surfeur par rapport à son surf, en particulier en position angulaire, en position longitudinale, ou en écartement d'un pied par rapport à l'autre.Another object of the invention is to allow, in addition, different adjustments of the position of the surfer's feet relative to his surf, in particular angular position, in the longitudinal position, or at a distance of one foot by compared to each other.

Un autre but de l'invention est de procurer en outre un bénéfique amortissement des vibrations.Another object of the invention is to further provide a beneficial vibration damping.

Parmi les systèmes de fixation de la chaussure du surfeur existent actuellement les fixations du type « coque », ou « soft binding » en anglais, qui ont pour avantage de pouvoir recevoir des chaussures qui sont suffisamment souples pour permettre à l'utilisateur de les utiliser également comme chaussures de marche bien plus confortables que les classiques chaussures de ski ou de surf à semelle rigide.Among the fastening systems of the surfer's shoe exist currently the bindings of the type "hull", or "soft binding" in English, which have the advantage of being able to receive shoes that are sufficiently flexible to allow the user to use them also as shoes much more comfortable than traditional ski or snowboard boots rigid sole.

Les chaussures appelées « bottes de surf » ou « surf boots » sont par exemple pratiquement aussi agréables à porter que les bottes de neige, ou « snow boots ».The shoes called "surf boots" or "surf boots" are by example almost as comfortable to wear as snow boots, or "snow boots ".

Ces fixations de type coque comportent, outre une plaque de réception de la semelle de la chaussure, un appui arrière articulé qui remonte sur l'arrière du tendon d'Achille jusqu'environ au niveau de la cheville, et deux sangles de retenue de la chaussure, dont l'une est serrée autour du cou de pied et l'autre est serrée autour de l'avant du pied, environ au niveau de la naissance des orteils.These hull-type fasteners include, in addition to a receiving plate of the sole of the shoe, an articulated rear support which rises on the rear of the Achilles tendon up to around the ankle, and two straps shoe retainer, one of which is tight around the instep and the other is tight around the front of the foot, about at the birth of the toes.

Ces fixations de type coque ne peuvent pas non plus être rapportées telles qu'elles sur un surf de neige qui ne présente pas la possibilité de loger un point d'ancrage à l'endroit où ces fixations doivent être placées, en raison, en particulier pour un surf présentant un évidement longitudinal médian, d'une épaisseur insuffisante à cet endroit. Un autre but de la présente invention est de remédier à cet inconvénient.These shell-type fasteners cannot be brought back either as they are on a snowboard that does not have the possibility of housing a anchor point where these fasteners are to be placed, due, in particular for a surfboard having a median longitudinal recess, of a insufficient thickness at this point. Another object of the present invention is to remedy this drawback.

Un autre but de l'invention est de permettre en outre, pour ces fixations de type coque, différents réglages, en position angulaire, de la position des pieds du surfeur par rapport à son surf.Another object of the invention is to allow, in addition, for these shell type fasteners, different settings, in angular position, position of the surfer's feet in relation to his surf.

En ce qui concerne ces fixations de type coque, la plaque rigide qui reçoit la semelle de la chaussure est fixée sur le surf en position sensiblement transversale. Ceci a pour inconvénient de rigidifier le surf dans le sens transversal, et donc de brider celui-ci en flexion transversale, ce qui est très gênant car justement un surf est étudié, par le fabricant, pour avoir des propriétés bien définies aussi bien en flexion longitudinale (ou « flexion simple ») qu'en flexion transversale (c'est-à-dire : en flexion dans le sens orthogonal à l'axe du surf).With regard to these shell-type fasteners, the rigid plate which receives the sole of the shoe is fixed on the surf in a substantially position cross. This has the disadvantage of stiffening the surf in the transverse direction, and therefore to clamp it in transverse bending, which is very annoying because precisely a surfboard is studied, by the manufacturer, to have good properties defined both in longitudinal bending (or "simple bending") and in bending transverse (that is to say: in bending in the direction orthogonal to the axis of the surf).

Un autre but de l'invention vise tout d'abord à remédier à cet inconvénient, s'agissant d'un surf présentant un évidement longitudinal médian.Another object of the invention aims first of all to remedy this drawback, in the case of a surf having a median longitudinal recess.

Un autre but de l'invention est d'améliorer, par rapport aux fixations de type « coque » connues actuellement, la transmission au surf des efforts par les deux extrémités du pied : orteils et talon. Avec les fixations actuelles, la rigidité de la plaque de base unique, et la fixation de cette plaque relativement proche de l'axe longitudinal médian du surf, pénalisent cette transmission des efforts par les deux extrémités du pied.Another object of the invention is to improve, compared to the fasteners of the “hull” type currently known, the transmission to the surf of the forces by the two ends of the foot: toes and heel. With current fixings, the rigidity of the single base plate, and the fixing of this plate relatively close to the median longitudinal axis of the surf, penalize this transmission of forces by two ends of the foot.

Un autre but de l'invention est d'assurer, par rapport à ces fixations de type « coque » connues, et pour un surf à évidement longitudinal médian, un meilleur maintien des deux extrémités - avant et arrière - de la chaussure, et donc d'éviter un décollement - par rapport à la surface du surf - de ces deux extrémités lors de la pratique de la glisse sur neige.Another object of the invention is to ensure, with respect to these fasteners known hull type, and for a board with a median longitudinal recess, a better support of the two ends - front and rear - of the shoe, and therefore avoid detachment - from the surface of the surf - of these two ends when practicing snow sliding.

L'invention se rapporte donc à un ensemble de glisse sur neige comprenant un surf des neiges et un système de réception des chaussures du surfeur, ce surf des neiges se décomposant, dans le sens longitudinal, en une zone arrière, une zone médiane, et une zone avant, et dont la structure se compose, du bas vers le haut :

  • en ce que des points d'ancrage sont ménagés dans ces deux longerons latéraux longitudinaux,

  • of a nucleus,
  • one or more upper reinforcement layers,

    The invention also relates to a set of gliding on snow of the type as first defined above, and of which the shoe fastening device at least comprises, for each foot respectively, a base plate, distinct, for receiving the sole of the shoe, characterized in that this plate for receiving the sole of the shoe is equipped with at least two families of orifices or lights intended for anchoring this plate on the surf:

    En se référant tout d'abord à l'ensemble des figures 1 à 4, il s'agit d'un surf des neiges destiné à équiper l'ensemble de glisse sur neige de l'invention et se décomposant, dans le sens longitudinal, en une zone arrière 20, une zone médiane 21, et une zone avant 22, et dont la structure est de type dit « rectangulaire » et comporte :

    • Une surface de glisse composée d'une semelle de glissement 1 bordée par des carres métalliques latérales 2, 3,
    • Des chants latéraux rigides 4, 5,
    • Une couche de renfort inférieure 6 constituée en matériau fibreux,
    • Une couche supérieure 7 de protection et de décor, formant la surface supérieure de la planche, composée d'une matière plastique souple et bordée intérieurement d'une couche de renfort supérieure 8, elle aussi constituée en matériau fibreux,
    • Un noyau en Polyuréthanne qui, selon la présente invention, est composé de trois barreaux longitudinaux distincts, dont un barreau central et axial 9, et deux barreaux latéraux 10, 11 disposés de part et d'autre du noyau médian 9, et formant donc deux longerons latéraux.
    Referring firstly to all of FIGS. 1 to 4, this is a snowboard intended to equip the set of gliding on snow of the invention and breaking down, in the longitudinal direction, in a rear zone 20, a central zone 21, and a front zone 22, and the structure of which is of the so-called “rectangular” type and comprises:
    • A sliding surface composed of a sliding sole 1 bordered by lateral metal edges 2, 3,
    • Rigid side edges 4, 5,
    • A lower reinforcing layer 6 made of fibrous material,
    • An upper protective and decorative layer 7, forming the upper surface of the board, composed of a flexible plastic material and internally bordered by an upper reinforcing layer 8, also made of fibrous material,
    • A polyurethane core which, according to the present invention, is composed of three separate longitudinal bars, including a central and axial bar 9, and two lateral bars 10, 11 arranged on either side of the median core 9, and therefore forming two side rails.

    En outre :

    • La surface supérieure du surf comporte un substantiel évidement longitudinal médian 12, qui s'étend ici sur une longueur englobant la zone médiane 21 du surf, qui comprend les deux zones Z1 et Z2 de positionnement de chaque pied (pied avant et pied arrière respectivement) du surfeur, et s'étendant, dans cet exemple non limitatif, sensiblement sur la longueur portante de ce surf, c'est-à-dire sensiblement entre la ligne de contact avant 31 et une ligne située à proximité de la ligne de contact arrière 32. La profondeur P et la largeur L de cette saignée axiale 12 sont conséquentes. Dans cet exemple de réalisation, cette profondeur varie le long du surf, selon la position considérée sur celui-ci, le fond 16 de la saignée 12 suivant ici approximativement l'allure de la surface inférieure du surf, tandis que la largeur L, qui ici varie elle aussi le long du surf, comme représenté sur la figure 1, est ici comprise entre un cinquième et trois cinquièmes de la largeur de la planche. Cette profondeur P est déterminée ici par l'épaisseur de matière résiduelle dans la zone médiane 21. Dans le cas présent, l'épaisseur de matière résiduelle est sensiblement égale à l'épaisseur du surf en spatule et au talon. La profondeur P de la saignée 12 permet, conformément à un aspect avantageux de l'invention, d'ajuster à loisir la répartition de raideur du surf, de manière à obtenir un surf ayant des caractéristiques particulières souhaitées.
    • Chacun des deux barreaux latéraux droite/gauche 11, 10 est gainé, en structure dite « structure caisson » en termes du métier, par une enveloppe respective 14, 13 en matériau de renfort fibreux, par exemple le même matériau que pour les renforts inférieur 6 et supérieur 8, pour former ainsi un longeron latéral 23, 24 à structure caisson, ces deux longerons en caisson 23, 24 étant placés, respectivement, quasi immédiatement de part et d'autre dudit évidement ou saignée 12.
    • Les points d'ancrage 19 des dispositifs de fixation des chaussures sont ménagés dans ces deux longerons en caisson 23, 24. Ces points d'ancrage sont assurés soit par des inserts 17, 18, préalablement percés ou non, logés à l'intérieur de chacun des caissons 10, 11, soit par des renforts mécaniques supplémentaires destinés à garantir une bonne résistance à l'arrachement des vis d'attache de la fixation. Ils peuvent aussi être tout simplement obtenus, au montage de la fixation, par perçage des caissons 10, 11.
    In addition :
    • The upper surface of the surf has a substantial median longitudinal recess 12, which here extends over a length encompassing the central zone 21 of the surf, which comprises the two zones Z1 and Z2 for positioning each foot (front foot and rear foot respectively) of the surfer, and extending, in this nonlimiting example, substantially over the bearing length of this surf, that is to say substantially between the front contact line 31 and a line located near the rear contact line 32. The depth P and the width L of this axial groove 12 are substantial. In this exemplary embodiment, this depth varies along the surf, according to the position considered thereon, the bottom 16 of the groove 12 here following approximately the shape of the bottom surface of the surf, while the width L, which here also varies along the surf, as shown in Figure 1, is here between one fifth and three fifths of the width of the board. This depth P is determined here by the thickness of residual material in the middle zone 21. In the present case, the thickness of residual material is substantially equal to the thickness of the tip and tip surf. The depth P of the groove 12 makes it possible, in accordance with an advantageous aspect of the invention, to adjust the stiffness distribution of the surf at leisure, so as to obtain a surf having particular desired characteristics.
    • Each of the two right / left side bars 11, 10 is sheathed, in a structure called “box structure” in terms of the trade, by a respective envelope 14, 13 made of fibrous reinforcing material, for example the same material as for the lower reinforcements 6 and upper 8, to thereby form a lateral spar 23, 24 with a box structure, these two box spars 23, 24 being placed, respectively, almost immediately on either side of said recess or groove 12.
    • The anchor points 19 of the shoe fastening devices are formed in these two box rails 23, 24. These anchor points are provided either by inserts 17, 18, previously drilled or not, housed inside each of the boxes 10, 11, either by additional mechanical reinforcements intended to guarantee good resistance to tearing of the fastening screws of the fixing. They can also be quite simply obtained, when the fixing is mounted, by drilling the boxes 10, 11.

    Dans le cas de figure représenté aux figures 3 et 4, les poutres latérales 10 et 11 ont chacune une section rectangulaire. Le barreau central 9, qui est positionné sous l'évidement 12, a une section rectangulaire très aplatie comme on le voit sur la figure 3.In the case shown in Figures 3 and 4, the side beams 10 and 11 each have a rectangular section. The central bar 9, which is positioned under the recess 12, has a very flat rectangular section as see it in figure 3.

    Chacun des longerons latéraux 23, 24 est respectivement placé quasi immédiatement de part et d'autre de l'évidement central 12.Each of the side rails 23, 24 is respectively placed almost immediately on either side of the central recess 12.

    A noter que, dans cet exemple de réalisation, les parties inférieures des deux gaines fibreuses 13 et 14 sont superposées à la couche de renfort inférieure 6. De même, la couche de renfort supérieure 8 épouse en grande partie les parois latérales et supérieures de ces deux gaines 13 et 14.Note that, in this embodiment, the lower parts of the two fibrous sheaths 13 and 14 are superimposed on the lower reinforcing layer 6. Likewise, the upper reinforcing layer 8 largely hugs the walls. lateral and upper of these two sheaths 13 and 14.

    Selon la variante de la figure 5, la saignée 12 est plus profonde à l'avant du surf qu'à l'arrière de celui-ci. On obtient ainsi un surf qui est plus souple dans sa partie avant que dans sa partie arrière. Ce mode de réalisation donne un surf plus facile à inscrire en courbe, mais conservant néanmoins une bonne tenue lors d'un virage, car l'arrière, plus raide, n'a alors pas tendance à décrocher.According to the variant of Figure 5, the groove 12 is deeper at the front of the surf than at the back of it. We thus obtain a surf which is more flexible in its front part than in its rear part. This embodiment gives a surf easier to register on a curve, but nevertheless retaining good hold during a turn, as the rear, which is steeper, does not tend to stall.

    Selon la variante de la Figure 6, là profondeur P de la saignée 12 est variable continûment dans le plan transversal, de sorte qu'elle est plus grande sur un côté, ici le côté droit. Ceci a pour effet bénéfique de durcir un coté par rapport à l'autre : dans le cas de figure représenté ici, le côté gauche est plus raide que le côté droit.According to the variant of Figure 6, the depth P of the groove 12 is continuously variable in the transverse plane, so that it is larger on one side, here the right side. This has the beneficial effect of hardening one side with respect to to the other: in the case shown here, the left side is stiffer than the right side.

    Le réglage de raideur locale peut, de façon analogue, être obtenu en faisant varier, sur au moins une portion de sa longueur, la largeur L de la saignée 12.The local stiffness adjustment can similarly be obtained by varying, over at least a portion of its length, the width L of the groove 12.

    Selon la variante de la figure 7, la saignée 12 a pratiquement la même longueur que la zone médiane 21 du surf. Par ailleurs, pour illustrer le caractère non limitatif de l'invention, sa largeur L est constante. De même façon, sa profondeur P peut être constante elle aussi, ce qui facilite grandement l'usinage. Bien entendu, cette constance de la profondeur P et/ou de la largeur L est applicable aux autres modes possibles de réalisation.According to the variant of FIG. 7, the groove 12 has practically the same length than the middle area 21 of the surf. By the way, to illustrate the character not limiting of the invention, its width L is constant. Similarly, its depth P can also be constant, which greatly facilitates machining. Of course, this constancy of the depth P and / or the width L is applicable to other possible embodiments.

    La variante de la figure 8 illustre une réalisation d'un surf de forme dite « coque », c'est à dire d'un surf dont la couche supérieure 7 de protection et de décor constitue aussi les faces latérales du surf. Ce surf comporte des inserts métalliques 17, 18, noyés dans le Polyuréthanne et qui constituent les points d'ancrage des dispositifs de fixation des chaussures du surfeur.The variant of Figure 8 illustrates an embodiment of a so-called surfboard "Shell", that is to say a surfboard whose upper layer 7 of protection and decor also constitutes the lateral faces of the surf. This surf has inserts metallic 17, 18, embedded in the Polyurethane and which constitute the points anchoring devices for fixing the surfer's shoes.

    A noter que , dans ce mode de réalisation, les deux longerons latéraux 23, 24 ont chacun une section de forme sensiblement trapézoïdale.Note that, in this embodiment, the two side rails 23, 24 each have a substantially trapezoidal cross section.

    La figure 9 illustre une autre variante de réalisation d'un surf pour ensemble de glisse conforme à l'invention, mais qui présente les particularités suivantes :

    • Il ne comporte pas de noyau central 9, mais en revanche il comporte une plaque de renfort inférieur 25, surplombant la semelle 1 et constituée d'une plaque métallique, typiquement en alliage d'Aluminium, située entre les ailettes des carres 2, 3 et dans le prolongement de ces ailettes. Dans cette forme de réalisation, le renfort supérieur fibreux 8 recouvre les parties latérales et supérieures des longerons en caisson 24, 23. Il recouvre la plaque métallique 25 dans la partie centrale du surf, comme représenté.
    • Ses longerons latéraux 23, 24 ont chacun une section de forme arrondie en demi-cercle, au lieu d'avoir une forme trapézoïdale comme c'est le cas pour la réalisation selon la figure 8.
    • Les deux noyaux 10, 11 de ces longerons 24, 23 sont en bois, et les inserts métalliques précités 17, 18 sont rapportés dans ces noyaux 10, 11 par usinage de ceux-ci.
    FIG. 9 illustrates another alternative embodiment of a board for gliding assembly according to the invention, but which has the following particularities:
    • It does not have a central core 9, but on the other hand it has a lower reinforcement plate 25, overhanging the sole 1 and consisting of a metal plate, typically made of aluminum alloy, located between the fins of the edges 2, 3 and in the extension of these fins. In this embodiment, the upper fibrous reinforcement 8 covers the lateral and upper parts of the box rails 24, 23. It covers the metal plate 25 in the central part of the surf, as shown.
    • Its lateral beams 23, 24 each have a cross-section in the form of a semicircle, instead of having a trapezoidal shape as is the case for the embodiment according to FIG. 8.
    • The two cores 10, 11 of these beams 24, 23 are made of wood, and the aforementioned metal inserts 17, 18 are attached to these cores 10, 11 by machining them.

    Comme il va de soi, la construction d'un surf pour ensemble de glisse selon l'invention n'est pas limitée aux exemples de réalisation qui viennent d'être décrits. C'est ainsi que, selon les modes de réalisation, la profondeur P de l'évidement ou saignée 12 :

    • est constante dans la longueur de la planche selon la position considérée sur celui-ci, le fond 16 de l'évidement 12 suivant approximativement l'allure de la surface supérieure 15 de cette planche ;
    • varie dans la longueur de la planche selon la position considérée sur celui-ci, cette variation de profondeur étant différente vers l'avant et vers l'arrière de cette planche ;
    • varie dans la longueur de la planche selon la position considérée sur celui-ci, cette variation de profondeur étant sensiblement identique vers l'avant ou vers l'arrière de cette planche, de façon donc sensiblement symétrique (figure 2) par rapport au point médian le plus élevé (30, figures 2 et 5) de la planche ;
    • varie dans la largeur de la planche de sorte qu'elle est plus grande d'un coté que de l'autre (figure 6) ;
    • varie dans la longueur de la planche selon la position considérée sur celui-ci, cette variation de profondeur étant différente vers l'avant et vers l'arrière de cette planche, de façon donc asymétrique par rapport au point médian le plus élevé 30 de la planche.
    As it goes without saying, the construction of a board for a sliding assembly according to the invention is not limited to the exemplary embodiments which have just been described. Thus, according to the embodiments, the depth P of the recess or groove 12:
    • is constant in the length of the board according to the position considered thereon, the bottom 16 of the recess 12 approximately following the shape of the upper surface 15 of this board;
    • varies in the length of the board according to the position considered thereon, this variation in depth being different towards the front and towards the rear of this board;
    • varies in the length of the board according to the position considered thereon, this variation in depth being substantially identical towards the front or towards the rear of this board, therefore in a manner substantially symmetrical (FIG. 2) relative to the midpoint the highest (30, Figures 2 and 5) of the board;
    • varies in width of the board so that it is larger on one side than the other (Figure 6);
    • varies in the length of the board according to the position considered thereon, this variation in depth being different towards the front and towards the rear of this board, so asymmetrically with respect to the highest midpoint 30 of the board.

    C'est ainsi que le fond 16 de la saignée 12 peut être plan ou de forme non plane, concave ou convexe..., tandis que la largeur L de cette saignée peut être soit constante, soit variable le long de cette saignée.This is how the bottom 16 of the groove 12 can be flat or shaped not flat, concave or convex ..., while the width L of this groove can be either constant or variable along this bleeding.

    En se référant maintenant aux figures 10 et 11, il est représenté un surf de neige 101 qui, tel que décrit ci-dessus, présente un évidement axial et longitudinal 102 qui définit deux nervures ou longerons longitudinaux 103, 104 de part et d'autre.Referring now to Figures 10 and 11, a surf is shown snow 101 which, as described above, has an axial recess and longitudinal 102 which defines two longitudinal ribs or longitudinal members 103, 104 of on both sides.

    La surface supérieure du surf n'étant pas plane, et de plus ce surf ne présentant pas de possibilité d'accrochage de la fixation dans la zone centrale, du fait de la faible épaisseur du surf à cet endroit, une fixation classique ne peut pas convenir pour ce genre de surf.The upper surface of the surf not being flat, and moreover this surf does not having no possibility of attachment of the attachment in the central zone, of the due to the thinness of the surf at this point, a classic binding cannot suitable for this kind of surfing.

    L'invention prévoit d'utiliser, pour ce genre de surf, un dispositif d'interface intermédiaire, à placer entre le surf et la fixation concernée, qui est constitué par une plaque rigide, respectivement 105 relativement à la fixation avant et 106 relativement à la fixation arrière.The invention provides for using, for this kind of surfing, a device intermediate interface, to be placed between the surfboard and the binding concerned, which is constituted by a rigid plate, respectively 105 relative to the fixing front and 106 relative to the rear attachment.

    Cette plaque rigide, 105 ou 106, comporte des moyens d'ancrage dans chacun des bords latéraux 103 et 104 de la planche. Ces moyens d'ancrage sont ici constitués par deux orifices 107 de passage de vis de bridage pour l'ancrage dans le bord 103, et par deux autres orifices 108 de passage de vis de bridage pour l'ancrage dans l'autre bord 104.This rigid plate, 105 or 106, includes means for anchoring in each of the side edges 103 and 104 of the board. These anchoring means are here constituted by two orifices 107 for the passage of clamping screws for anchoring in the edge 103, and by two other orifices 108 for the passage of clamping screws for anchoring in the other edge 104.

    En outre, et c'est un avantage important pour pouvoir utiliser les fixations aisément disponibles dans le commerce, chaque plaque rigide 105, 106 comporte, dans la zone centrale de cette plaque qui vient localement recouvrir l'évidement 102, huit trous taraudés qui sont positionnés en correspondance avec les orifices existant traditionnellement sur les fixations du commerce. Les fixations avant et arrière sont ainsi reçues respectivement, dans ces trous taraudés 109, sur la plaque intermédiaire avant 105 et sur la plaque intermédiaire arrière 106. In addition, and this is an important advantage to be able to use the fasteners readily available commercially, each rigid plate 105, 106 has, in the central area of this plate which locally covers the recess 102, eight tapped holes which are positioned in correspondence with the orifices traditionally existing on commercial fasteners. The front and rear fasteners are thus received respectively, in these tapped holes 109, on the front intermediate plate 105 and on the rear intermediate plate 106.

    A noter qu'ici, bien que ce ne soit basiquement pas obligatoire pour la mise en oeuvre de l'invention, les plaques intermédiaires 105 et 106 sont rapportées sur le surf 101 par l'intermédiaire d'une plaque 110 en matériau présentant des caractéristiques amortissantes, par exemple une plaque 110 en matériau viscoélastique, ce qui ajoute un élément de confort à ce surf.Note that here, although it is not basically mandatory for the implementation of the invention, the intermediate plates 105 and 106 are reported on the surf 101 by means of a plate 110 of material having damping characteristics, for example a plate 110 in viscoelastic material, which adds an element of comfort to this surf.

    Les plaques rigides 105, 106 sont avantageusement constituées d'un métal léger, par exemple elles sont en acier nervuré ou en alliage d'aluminium. Elles peuvent être aussi constituées d'un matériau plastique rigide ou d'un matériau réalisé à partir de fibres de verre ou de fibres de carbone.The rigid plates 105, 106 advantageously consist of a light metal, for example they are made of ribbed steel or aluminum alloy. They can also be made of a rigid plastic material or a material made from glass fibers or carbon fibers.

    La figure 12 illustre une variante de réalisation pour laquelle les paires d'orifices 107, 108 sont remplacées chacune par une lumière longitudinale, 170 et 180 respectivement, ce qui permet un réglage longitudinal de la position des plaques intermédiaires 105 et 106.FIG. 12 illustrates an alternative embodiment for which the pairs orifices 107, 108 are each replaced by a longitudinal lumen, 170 and 180 respectively, which allows a longitudinal adjustment of the position of the intermediate plates 105 and 106.

    Dans ce cas, il n'est pas nécessaire de prévoir huit trous taraudés, car le réglage d'écartement est obtenu par les lumières 170 et 180.In this case, it is not necessary to provide eight tapped holes, because the spacing adjustment is obtained by lights 170 and 180.

    La figure 13 illustre une variante de réalisation pour laquelle les paires d'orifices 107, 108 sont remplacées chacune par une lumière en arc de cercle, 171 et 181 respectivement, ce qui permet un réglage angulaire de la position des plaques intermédiaires 105 et 106.FIG. 13 illustrates an alternative embodiment for which the pairs orifices 107, 108 are each replaced by a light in an arc, 171 and 181 respectively, which allows angular adjustment of the position of the intermediate plates 105 and 106.

    La figure 14 illustre une variante de réalisation pour laquelle les deux orifices 108 du côté des pointes de pieds sont remplacés par des lumières transversales 182 ce qui permet, comme l'illustre la figure 15 où le surf 101 est basculé, typiquement lors de l'exécution d'un virage, sur sa carre 111 côté talons du surfeur, de ne pas contrecarrer la déformation transversale, en arc de cercle comme représenté, du surf. Dans ce cas, les vis d'ancrage des plaques 105, 106 côtés pointes de pieds du surfeur sont des vis d'ancrage à serrage glissant qui permettent un coulissement à l'intérieur de la lumière. Ce sont, par exemple, des vis épaulées.FIG. 14 illustrates an alternative embodiment for which the two holes 108 on the toe side are replaced by lights transverse 182 which allows, as illustrated in FIG. 15 where the surf 101 is tilted, typically when executing a turn, on its edge 111 on the heels side of the surfer, not to counteract the transverse deformation, in an arc as shown, surfing. In this case, the anchor screws of the plates 105, 106 surfer's toe sides are sliding clamp anchor screws that allow sliding inside the light. These are, for example, shoulder screws.

    A noter que, pour illustrer le caractère non limitatif de l'invention, les orifices 109 de réception des fixations sont ici des orifices disposés en triangle, ce qui correspond aussi à un standard de liaison des fixations qui est disponible dans le commerce.Note that, to illustrate the non-limiting nature of the invention, the orifices 109 for receiving the fasteners are here orifices arranged in a triangle, this which also corresponds to a binding binding standard which is available in trade.

    La combinaison, selon l'invention, d'un surf à évidement longitudinal 102 avec une plaque intermédiaire 105, 106 permet, telle qu'illustré sur la figure 16, d'utiliser, pour la réception des fixations au niveau de la zone évidée 102 située entre les bords du surf en forme de nervures 103 et 104, d'utiliser des lumières longitudinales 191 remplaçant les trous taraudés 109. Il suffit alors de remplacer les vis d'ancrage des fixations par des systèmes vis-écrous pouvant coulisser, avant serrage, dans ces lumières 191, pour obtenir très simplement, sans toucher à la position des plaques intermédiaires 105 et 106, une possibilité de réglage longitudinal de la position des fixations sur le surf 101.The combination, according to the invention, of a board with longitudinal recess 102 with an intermediate plate 105, 106 allows, as illustrated in the figure 16, to use, for the reception of the fixings at the level of the hollowed-out area 102 located between the edges of the surf in the form of ribs 103 and 104, to use longitudinal slots 191 replacing the tapped holes 109. It then suffices to replace the anchor bolts of the fixings with screw-nut systems which can slide, before tightening, in these lights 191, to obtain very simply, without touch the position of the intermediate plates 105 and 106, a possibility of longitudinal adjustment of the position of the bindings on the surf 101.

    La figure 17 illustre une variante de réalisation pour laquelle les deux plaques intermédiaires 105 et 106 sont remplacées par une plaque intermédiaire unique 112, suffisamment longue pour recevoir à la fois la fixation avant et la fixation arrière, et munie en conséquence d'orifices 107, 108, 109 aussi bien sur sa partie avant 105 que sur la partie arrière 106.FIG. 17 illustrates an alternative embodiment for which the two intermediate plates 105 and 106 are replaced by an intermediate plate single 112, long enough to receive both the front mounting and the rear attachment, and consequently provided with holes 107, 108, 109 as well on its front part 105 than on the rear part 106.

    A noter qu'ici, les parties avant 105 et arrière 106 de cette plaque unique 112 sont réunies par une partie moins large 113, ce qui réalise une économie de poids et de matière.Note that here, the front 105 and rear 106 parts of this plate single 112 are joined by a narrower part 113, which achieves a saving in weight and material.

    En se référant maintenant à la figure 18, il s'agit d'une fixation de type « coque » pour surf des neiges à évidement longitudinal médian, et par exemple donc pour surf des neiges selon les figures 1 à 9.Referring now to FIG. 18, this is a type of attachment. "Shell" for snowboarding with median longitudinal recess, and for example therefore for snowboarding according to FIGS. 1 to 9.

    Cette fixation comporte classiquement une plaque 201 de réception de la semelle de la chaussure, à bords latéraux 202, 203 relevés, un appui arrière articulé 204 qui remonte sur l'arrière du tendon d'Achille jusqu'environ au niveau de la cheville, et deux sangles de maintien de la chaussure, dont une sangle arrière 205 qui se serre autour du cou de pied et une sangle avant 206 qui se serre autour de l'avant du pied, environ au niveau de la naissance des orteils, ces deux sangles 205, 206 étant fixées et articulées sur les rebords latéraux 202, 203 de la plaque de réception 201. This fixing conventionally comprises a plate 201 for receiving the sole of the shoe, with side edges 202, 203 raised, a rear support articulated 204 which goes up on the back of the Achilles tendon until about the level ankle, and two shoe retention straps, including a rear strap 205 which tightens around the instep and a front strap 206 which tightens around of the forefoot, approximately at the level of the birth of the toes, these two straps 205, 206 being fixed and articulated on the lateral flanges 202, 203 of the plate reception 201.

    Pour les fixations de l'art connu, elles viennent s'amarrer sur le surf à travers des orifices qui sont pratiqués dans la zone centrale 207 de leur plaque 201 de réception de la semelle de la chaussure. Elles ne peuvent alors pas être rapportées sur un surf, tel que celui représenté sur la figure 19, qui possède un évidement longitudinal 208 définissant respectivement de part et d'autre deux longerons latéraux et longitudinaux 209 et 210.For bindings of known art, they come to moor on the surf at through orifices which are made in the central zone 207 of their plate 201 receiving the sole of the shoe. They cannot then be reported on a surf, such as that shown in Figure 19, which has a longitudinal recess 208 defining respectively on either side two lateral and longitudinal beams 209 and 210.

    Tel n'est pas le cas pour la fixation selon la figure 18.This is not the case for the fixing according to FIG. 18.

    Celle-ci est en effet prévue pour s'amarrer dans les régions 209, 210 attenantes aux bords latéraux longitudinaux 211, 212 (figure 19) du surf récepteur. Elle comporte à cet effet (figure 18) :

    • A l'arrière de la plaque 201, une série 213 de trous d'amarrage 214 qui sont disposés selon un arc de cercle 215 dont le centre 216 est, grossièrement, situé dans la partie centrale 207 de la plaque 201, comme on le voit sur le dessin et donc sous la plante du pied du surfeur. Cette série 213 de trous 214 est positionnée au niveau de l'arrière de la chaussure à recevoir, sensiblement donc sous le talon du surfeur.
    • A l'avant de cette plaque 201, une série de lumières 217 d'amarrage allongées et rectilignes qui sont positionnées au niveau de l'avant de la chaussure à recevoir et donc grossièrement au niveau des orteils du surfeur, les axes longitudinaux 221 des lumières 217 étant orientés vers un point 216 positionné dans la zone centrale 207 de la plaque 201, les centres de ces lumières 217 étant situés sur un arc de cercle 220 de centre 216.
    This is in fact intended to moor in the regions 209, 210 adjoining the longitudinal lateral edges 211, 212 (FIG. 19) of the receiving surf. To this end, it includes (Figure 18):
    • At the rear of the plate 201, a series 213 of mooring holes 214 which are arranged in an arc 215 whose center 216 is roughly located in the central part 207 of the plate 201, as can be seen on the drawing and therefore under the sole of the surfer's foot. This series 213 of holes 214 is positioned at the rear of the shoe to be received, therefore substantially under the heel of the surfer.
    • At the front of this plate 201, a series of elongated and rectilinear docking slots 217 which are positioned at the front of the boot to be received and therefore roughly at the level of the surfer's toes, the longitudinal axes 221 of the slots 217 being oriented towards a point 216 positioned in the central area 207 of the plate 201, the centers of these openings 217 being located on an arc 220 with center 216.

    Comme on le voit sur la figure 19, ce type de fixation se monte facilement sur un surf 240 à évidement longitudinal central 208.As you can see in figure 19, this type of fixing is mounted easily on a board 240 with central longitudinal recess 208.

    En choisissant, pour l'amarrage de la fixation, au moins une paire « trou arrière - lumière avant » conjugués 340, 380, et 341, 381, et donc situés respectivement sur un même diamètre 222 et 223, on peut ajuster l'orientation angulaire de la fixation avant 226 et de la fixation arrière 227 par rapport à l'axe longitudinal médian 228 du surf 240. By choosing, for the anchoring of the binding, at least one pair "hole rear - front light 'conjugates 340, 380, and 341, 381, and therefore located respectively on the same diameter 222 and 223, the orientation can be adjusted angle of the front attachment 226 and the rear attachment 227 with respect to the axis longitudinal median 228 of the surf 240.

    A noter qu'avantageusement, une couche 218 de matière viscoélastique est rapportée sous la plaque de base 201.Advantageously, a layer 218 of viscoelastic material is reported under base plate 201.

    Les figures 20, 21, et 22 permettent d'expliquer comment les lumières avant 217 autorisent, par coulissement de classiques vis épaulées d'amarrage avant 233 dans ces lumières, un cintrage transversal aisé du surf 240 en cas d'appui intensif sur la carre arrière 219, ce qui permet de déconnecter l'action des pieds du surfeur par rapport à la raideur transversale du surf, et plus généralement d'éviter de brider le surf dans le sens transversal.Figures 20, 21, and 22 explain how the lights before 217 allow, by sliding conventional shoulder mooring screws before 233 in these lights, easy transverse bending of the surf 240 in case intensive support on the rear edge 219, which disconnects the action of feet of the surfer relative to the transverse stiffness of the surf, and more generally avoid clamping the board in the transverse direction.

    Les vis d'amarrage arrière 243, qui passent dans les trous 214, sont des vis ordinaires de blocage en position. En revanche, les vis d'amarrage avant 233 sont des vis épaulées qui viennent simultanément plaquer chaque fixation sur le dessus du surf, tout en l'autorisant à coulisser selon l'axe de la ou des lumières avant choisie(s) 217.The rear anchor screws 243, which pass through the holes 214, are ordinary screws for locking in position. However, the front anchor screws 233 are shouldered screws which simultaneously press each fastener onto the above the surf, while allowing it to slide along the axis of the light (s) before chosen 217.

    Les lumières 217 ont en conséquence une longueur L qui est supérieure à la largeur D de l'épaulement de la vis 233 (c'est-à-dire de la partie se trouvant sous la tête de la vis). Par ailleurs, bien entendu, l'épaisseur H1 de la plaque 201 doit être inférieure à la hauteur H2 de l'épaulement de la vis 233 (voir la figure 21). A noter que, selon Figure 21, la vis 233 est reçue classiquement dans un insert métallique 230 qui est noyé dans le corps du surf 240.The lights 217 consequently have a length L which is greater to the width D of the shoulder of the screw 233 (that is to say of the part lying under the head of the screw). Furthermore, of course, the thickness H1 of the plate 201 must be less than the height H2 of the shoulder of the screw 233 (see figure 21). Note that, according to Figure 21, the screw 233 is conventionally received in a metal insert 230 which is embedded in the body of the surfboard 240.

    La figure 22 illustre clairement, comme mentionné ci-dessus, le cintrage transversal du surf 223, et montre comment alors les vis épaulées avant 233 coulissent dans les lumières 217, de sorte qu'alors la fixation ne vient pas s'opposer à ce mouvement de cintrage du surf.Figure 22 clearly illustrates, as mentioned above, the transverse bending of the surf 223, and shows how then the front shoulder screws 233 slide in the lights 217, so that the fixing does not come to oppose this movement of bending the surf.

    La figure 23 illustre une variante de réalisation qui montre :

    • Que la série 213 de trous arrière 214 peut très bien être remplacée par une lumière, 331 ou 332, en arc de cercle.
    • Qu'il est possible d'obtenir une possibilité de réglage en position transversale de la fixation sur le surf en prévoyant non pas une seule, mais plusieurs lumières arrière, ici deux lumières arrière 331 et 332. La lumière 331, de rayon R1, a un centre 361 situé dans la zone centrale de la plaque 201, et la lumière 332, de rayon R2, a un centre 362 décalé, comme indiqué sur le dessin, d'un entraxe E par rapport au centre 361 de la lumière 331. On choisira alors, pour régler la position transversale de la plaque 201 par rapport au surf, l'une ou l'autre des lumières 331 et 332 pour amarrer la fixation. A noter qu'alors cet entraxe E devra être inférieur à la longueur L des lumières avant 217.
    • Que pour permettre un coulissement transversal de la vis épaulée 233 dans la lumière 217 malgré le désaxage E, il faut avoir un jeu qui correspond à une différence importante entre le diamètre D de la partie épaulée de la vis 233 et la largeur 1 de la lumière 217.
    FIG. 23 illustrates an alternative embodiment which shows:
    • That the series 213 of rear holes 214 may very well be replaced by a light, 331 or 332, in an arc of a circle.
    • That it is possible to obtain a possibility of adjustment in transverse position of the binding on the surf by providing not only one, but several rear lights, here two rear lights 331 and 332. The light 331, of radius R1, has a center 361 located in the central zone of the plate 201, and the light 332, of radius R2, has a center 362 offset, as indicated in the drawing, by a center distance E with respect to the center 361 of the light 331. We will then choose, to adjust the transverse position of the plate 201 relative to the surf, one or the other of the lights 331 and 332 to moor the fixing. Note that then this distance E must be less than the length L of the lights before 217.
    • That to allow a transverse sliding of the shouldered screw 233 in the light 217 despite the offset E, it is necessary to have a clearance which corresponds to a significant difference between the diameter D of the shouldered part of the screw 233 and the width 1 of the light 217.

    Comme il va de soi, l'invention s'applique non seulement à une fixation de type « coque », mais aussi à tout type de fixation qui possède, pour chaque pied respectivement, une plaque de base distincte, telle que la plaque 201, destinée à recevoir la semelle de la chaussure du surfeur.It goes without saying that the invention applies not only to a fixing "shell" type, but also to any type of attachment which has, for each leg respectively, a separate base plate, such as plate 201, intended for receive the sole of the surfer's shoe.

    Dans le cas de la variante selon la figure 23, il est bien évident que l'une et/ou l'autre des lumières arrière 331 et 332 pourraient être remplacées par une série de trous arrière comme c'est le cas pour la réalisation selon la figure 20.In the case of the variant according to Figure 23, it is obvious that one and / or the other of the rear lights 331 and 332 could be replaced by a series of rear holes as is the case for the embodiment according to FIG. 20.

    En se référant maintenant à la figure 24, il est représenté une autre fixation de type « coque » pour surf des neiges à évidement longitudinal médian, qui est cette fois-ci constituée de deux parties distinctes :

    • Une partie avant 301, chargée de recevoir la partie avant de la chaussure ou botte souple et comportant une plaque de base 302, rigide et métallique, à bords latéraux relevés 303, 304, cette plaque rigide 302 comprenant une lumière transversale 305 en arc de cercle dont la concavité est dirigée vers l'emplacement de la plante du pied, cette lumière étant destinée au passage des moyens d'ancrage de cette partie avant 301 sur le surf. Les bords relevés 303, 304 de cette plaque 302 reçoivent classiquement, au moyen d'écrous de fixation et d'articulation respectifs 306, 307, une sangle 308 de maintien de l'avant de la chaussure qui se serre classiquement autour de l'avant du pied, environ au niveau de la naissance des orteils.
    • Une partie arrière 309, chargée de recevoir la partie arrière de la chaussure ou botte souple et comportant une plaque de base 310, rigide et métallique, à bords latéraux relevés 331, 341 et reliés l'un à l'autre par une bande arrière courbe 313 servant d'appui pour le tendon d'Achille. Sur les bords latéraux 331, 341 s'articulent classiquement, autour de deux écrous respectifs 314, d'une part une sangle arrière 315 qui se serre autour du cou de pied, et d'autre part un appui arrière, ou « spoiler », 316 qui remonte sur l'arrière du tendon d'Achille jusqu'environ au niveau de la cheville. La plaque de base rigide 310 comprend une lumière transversale 317 en arc de cercle dont la concavité est dirigée vers l'emplacement de la plante du pied, cette lumière étant destinée au passage des moyens d'ancrage de cette partie arrière 309 sur le surf.
    Referring now to FIG. 24, there is shown another binding of the “shell” type for snowboarding with median longitudinal recess, which this time consists of two distinct parts:
    • A front part 301, responsible for receiving the front part of the flexible shoe or boot and comprising a base plate 302, rigid and metallic, with raised lateral edges 303, 304, this rigid plate 302 comprising a transverse light 305 in an arc of a circle whose concavity is directed towards the location of the sole, this light being intended for the passage of the anchoring means of this front part 301 on the surf. The raised edges 303, 304 of this plate 302 conventionally receive, by means of respective fixing and articulation nuts 306, 307, a strap 308 for holding the front of the shoe which is conventionally tightened around the front of the foot, approximately at the level of the birth of the toes.
    • A rear part 309, responsible for receiving the rear part of the flexible shoe or boot and comprising a base plate 310, rigid and metallic, with raised lateral edges 331, 341 and connected to each other by a curved rear strip 313 serving as a support for the Achilles tendon. On the lateral edges 331, 341 are conventionally articulated, around two respective nuts 314, on the one hand a rear strap 315 which is tightened around the instep, and on the other hand a rear support, or “spoiler”, 316 which rises on the back of the Achilles tendon to about the level of the ankle. The rigid base plate 310 comprises a transverse lumen 317 in an arc, the concavity of which is directed towards the location of the sole of the foot, this lumen being intended for the passage of the anchoring means of this rear part 309 on the surf.

    La figure 25 montre cette fixation 301, 309 en place sur le surf des neiges 318. Ce dernier comporte classiquement des inserts métalliques tubulaires et taraudés 319, 320 dans lesquels sont fermement vissées des vis d'ancrage 321, 322 qui passent à travers les lumières 317 et 305.Figure 25 shows this attachment 301, 309 in place on the surf of the snows 318. The latter conventionally comprises tubular metal inserts and tapped 319, 320 into which anchor screws 321 are firmly screwed, 322 which pass through lights 317 and 305.

    Le surf 318 dont il s'agit ici est bien entendu un surf qui, à l'instar de ceux décrits précédemment, présente un évidement longitudinal médian 330 qui s'étend ici sensiblement sur la longueur portante Lp de la planche.The surf 318 in question here is of course a surf which, like those described above, has a median longitudinal recess 330 which here extends substantially over the bearing length Lp of the board.

    Sur la figure 26, les deux fixations - avant 391, 311 et arrière 392, 312 - sont représentées en place sur le surf 318. Les parties avant 311, 312 de ces deux fixations et leurs parties arrière 391, 392 sont schématisées par des rectangles pour ne pas alourdir le dessin.In Figure 26, the two fasteners - front 391, 311 and rear 392, 312 - are shown in place on the surf 318. The front parts 311, 312 of these two fasteners and their rear parts 391, 392 are shown diagrammatically by rectangles so as not to weigh down the drawing.

    Le surf 318 comporte, symétriquement de part et d'autre de son axe longitudinal médian 323 :

    • A l'avant : deux rangées 324, 325 de chacune quatre inserts 319, 320 régulièrement espacés. Les deux rangées 324, 325 sont parallèles à l'axe 323, symétriques l'une de l'autre par rapport à cet axe, et distantes de ce dernier d'une distance D supérieure à la moitié de la largeur minimale L du surf 318 dans la zone longitudinalement médiane de celui-ci. Dans cet exemple de réalisation, la distance D est sensiblement égale aux deux-tiers de la demi-largeur L.
    • A l'arrière : deux autres rangées 326, 327 de chacune quatre inserts 319, 320, ces deux rangées étant dimensionnées et positionnées de même façon que les deux rangées avant 324, 325, mais étant à l'arrière de celles-ci.
    The surf 318 comprises, symmetrically on either side of its median longitudinal axis 323:
    • At the front: two rows 324, 325 of each four inserts 319, 320 regularly spaced. The two rows 324, 325 are parallel to the axis 323, symmetrical to each other with respect to this axis, and distant from the latter by a distance D greater than half the minimum width L of the surf 318 in the longitudinally median zone thereof. In this exemplary embodiment, the distance D is substantially equal to two-thirds of the half-width L.
    • At the rear: two other rows 326, 327 of each four inserts 319, 320, these two rows being dimensioned and positioned in the same way as the two front rows 324, 325, but being at the rear thereof.

    Chaque lumière en arc de cercle - avant 351 et 352 pour la fixation avant et la fixation arrière respectivement, et arrière 471 et 472 pour ces mêmes fixations respectives - reçoit deux vis de fixation et est donc associée à deux inserts respectifs (deux inserts 320 pour chaque partie avant 311 et 312, et deux inserts 319 pour chaque partie arrière 391 et 392).Each light in an arc - before 351 and 352 for fixing front and rear mounting respectively, and rear 471 and 472 for these same respective fixings - receives two fixing screws and is therefore associated with two respective inserts (two 320 inserts for each front part 311 and 312, and two inserts 319 for each rear part 391 and 392).

    Les lumières étant toutes en arc de cercle, on voit, en se référant également aux figures 27 et 28, que l'on peut régler, avant serrage des vis d'ancrage, l'inclinaison angulaire de l'axe, respectivement 328, 329, de chaque fixation - avant et arrière - par rapport à l'axe longitudinal 323 du surf: il suffit pour ceci de faire tourner les parties avant 311, 312 et arrière 391, 392, cette rotation étant autorisée et guidée par les lumières 351, 352 et 471, 472.The lights are all in an arc, we see, by referring also in Figures 27 and 28, which can be adjusted, before tightening the screws anchor, the angular inclination of the axis, respectively 328, 329, of each fixing - front and rear - relative to the longitudinal axis 323 of the surfboard: it suffices for this to rotate the front parts 311, 312 and rear 391, 392, this rotation being authorized and guided by lights 351, 352 and 471, 472.

    Pour régler l'écartement longitudinal, ou « stance », entre la fixation avant 311, 391 et la fixation arrière 312, 392, il suffit de choisir les deux inserts 319 -parmi les quatre inserts de chaque rangée - en conséquence, ce qui en soi est bien classique pour d'autres systèmes de fixation.To adjust the longitudinal spacing, or "stance", between the fixing front 311, 391 and rear fixing 312, 392, just choose the two inserts 319 - among the four inserts of each row - accordingly, which in itself is classic for other fastening systems.

    La figure 29 - qu'il convient de comparer à la figure 27 - schématise une variante de réalisation de cette fixation.Figure 29 - which should be compared to Figure 27 - schematically an alternative embodiment of this attachment.

    Conformément à cette variante, il est prévu, pour chaque partie avant 312 et pour chaque partie arrière 392 de la fixation, deux lumières en arc de cercle - respectivement 821, 822 et 2021, 2022 - au lieu d'une seule. In accordance with this variant, provision is made for each front part 312 and for each rear part 392 of the binding, two lights in an arc - respectively 821, 822 and 2021, 2022 - instead of just one.

    Sur chaque partie - avant 312 et arrière 392 - de la fixation, les deux arcs de cercle formés par les lumières sont parallèles, ou, en d'autres termes, ces deux arcs de cercle sont concentriques.On each part - front 312 and rear 392 - of the binding, the two arcs of circle formed by the lights are parallel, or, in other words, these two arcs of a circle are concentric.

    Comme on le voit sur la figure 30, cette disposition permet de faire varier la distance d'entre la partie avant 312 et la partie arrière 392 de la fixation, en fonction de la pointure de la chaussure de l'utilisateur : il suffit pour ceci de choisir, pour l'ancrage dans le surf, l'une ou l'autre de ces deux lumières pour l'ancrage de chacune des deux parties 312 et 392.As seen in Figure 30, this arrangement allows vary the distance between the front part 312 and the rear part 392 of the binding, depending on the shoe size of the user: it suffices for this to choose, for anchoring in the surf, one or the other of these two lights for the anchoring of each of the two parts 312 and 392.

    Dans l'exemple de la figure 30, les deux lumières intérieures 822 et 2022 ont été sélectionnées par l'ancrage dans les inserts 319 et 320, ce qui donne le maximum d'écartement « d » entre la partie avant 312 et la partie arrière 392 de la fixation.In the example of FIG. 30, the two interior lights 822 and 2022 were selected by anchoring in inserts 319 and 320, which gives the maximum distance “d” between the front part 312 and the rear part 392 of fixation.

    Comme il va de soi, l'invention n'est pas limitée à ces deux derniers exemples de réalisation.It goes without saying that the invention is not limited to the latter two. examples of realization.

    C'est ainsi par exemple que l'une des deux parties - avant 301 ou arrière 309 - de la fixation pourrait être équipée d'un ou plusieurs orifices de passage d'une vis unique de fixation. Le réglage angulaire de la fixation s'effectuerait alors par rotation de cette partie autour de cette vis, l'autre partie étant comme précédemment équipée d'une ou plusieurs lumières en arc de cercle.For example, one of the two parts - before 301 or rear 309 - of the attachment could be equipped with one or more orifices of passage of a single fixing screw. The angular adjustment of the binding would then be done by rotation of this part around this screw, the other part being as previously equipped with one or more lights in an arc.

    C'est ainsi également que le réglage de l'écartement « d » entre les deux parties 301, 309 de la fixation pourrait se faire - plus classiquement - en montant les plaques de base 302 et/ou 310 dans une glissière de support et de maintien en position, comme cela se fait pour les fixations de ski.This is also how the adjustment of the spacing "d" between the two parts 301, 309 of the fixing could be done - more conventionally - in mounting the base plates 302 and / or 310 in a support and holding in position, as is done for ski bindings.
