Definitions
- the invention constitutes an improvement of the gliding boards used in a unique manner, and more specifically relates to the shims for raising the bindings mounted on such boards.
- Snowboarding techniques are being developed. After a period during which we used surfing mainly in powder snow and making relatively wide turns, the practice of slalom in groomed snow, with close and fast turns attracts more and more surfers. The edges are therefore more frequently put into action, with greater angles of inclination of the board.
- the width of the surf is mainly conditioned by the length of the surfer's shoe.
- the disadvantage observed on existing surfboards is that if the ends of the shoe overflow, during the inclination of the board, they risk touching the snow, therefore causing the surfer to fall.
- the objective of the invention is to allow the use of a single gliding board with a narrow median zone while avoiding the attachment of the bindings or of the boot on the snow, and this either in the case where the feet are substantially arranged across the board or in the case where these are arranged substantially along the longitudinal axis with an even narrower board.
- At least one shoe-binding assembly overflows, at least on one side of the board by a distance (D), and in that the height H of the wedge satisfies the following formula: H ⁇ D- (E + F) in which D represents the distance between the edge of the edge on the one hand and the projection in the plane of the lower surface of the board from the outermost point of the shoe-binding assembly on the other hand.
- the binding is raised by a sufficient height to obtain a maximum hooking angle limiting the risks of contact of the shoe-binding assembly with the snow, that is to say less than the angle of dropout.
- the attachment angle is the angle formed by the plane of the bottom surface of the board and the surface of the snow when the board is tilted around the bottom edge of the edge, so that the end of the shoe-binding assembly extending beyond the board, touches the snow.
- the attachment angle on a gliding board according to the invention is therefore equal to or greater than 45 °.
- a hooking angle greater than 60 ° that is to say a wedge whose height H satisfies the following formula: H ⁇ 1.73.D- (E + F)
- the upper surface of the wedge is parallel to the upper surface of the board.
- the upper surface of the wedge is inclined towards the front of the shoe relative to the upper face of the board.
- the wedge raises the rear more than the front of the shoe to correspond to the natural position of the user.
- the height H used in the formulas is, of course, the height of the wedge at the lowest point of the shoe-binding assembly.
- the wedge is made of a material chosen from the group containing wood, metal alloys, composite materials, and plastics.
- the wedge also has a layer of viscoelastic material which makes it possible to absorb part of the vibrations generated by the board.
- the wedge is produced in two distinct parts located respectively in the anterior zone and in the posterior zone of the boot.
- the wedge has recesses capable of lightening it.
- this can be composed of two parts, namely a stud of reduced width on which rests a plate of dimensions compatible with the fixing of the binding.
- the height H to be taken into account is the distance between the top of the surfboard and the base of the shoe-binding assembly.
- Figure 1 is a schematic top view of a board on which the feet are substantially across the longitudinal axis of the board.
- Figure 2 is a top view of a narrower board in which the feet are positioned substantially along the longitudinal axis of the board.
- Figure 3 is a section along the longitudinal plane of a shoe, of the board-wedge-binding assembly, showing the characteristic quantities of the invention.
- Figure 4 illustrates a variant of the invention shown in Figure 3 having an inclined wedge.
- Figures 5 and 6 are sections also along the longitudinal plane of a shoe of the invention for which the wedge is in two parts, respectively juxtaposed and superimposed.
- the single gliding board consists of a board (1) of generally elongated shape, symmetrical with respect to a median longitudinal plane (2).
- the invention also relates to surfboards having ends and / or asymmetrical dimension lines.
- This board has a tightening in its middle zone (3).
- the width L of this area is an important factor, because as already said, the current trend is to manufacture increasingly narrow surfboards.
- the board receives two fixings (4,5) which are arranged in an inclined manner with respect to the longitudinal axis of the board.
- these bindings (4,5) are placed across the longitudinal axis (2).
- the angles of inclination are different between the front foot and the rear foot.
- the axis (40) of the front leg (4) is oriented at an angle ( ⁇ ) between 20 ° and 90 ° relative to the axis longitudinal (2), the point of the foot being clearly heard directed towards the front of this position.
- the angle ( ⁇ ) formed by the axis (50) of the rear leg (5) with the longitudinal axis (2), is between 45 ° and 110 °, that is to say that the tip of the foot can be slightly directed either towards the front or towards the rear of the board, at the convenience of the user.
- the most commonly adopted position corresponds to 45 ° for ⁇ and 80 ° for ⁇ .
- the axes (40, 50) of the front feet (4) and rear (5) are oriented at an angle ( ⁇ , ⁇ ) between 0 and 20 ° relative to the longitudinal axis (2) of the board.
- the shoe (6.7) and the binding itself (8.9) form an assembly (4.5) whose length or width exceeds the width of the board, in particular with the new trend of narrow surfboards.
- this overhanging part (D) varies according to the position of the bindings and their orientation relative to the longitudinal plane of the board.
- the invention consists in raising the fixing (8,9) by means of a wedge (14) so as to increase the value of the angle ⁇ which conditions the limit of inclination of the board before hanging.
- This angle ⁇ is at the top of the edge (10) of the edge (11). It is measured between the plane (12) of the lower surface of the board (1) and the plane (13) tangent to the shoe-binding assembly (4,5). This angle corresponds to the inclination limit that the board can take during tight turns, without the binding touching the snow and therefore causing the fall.
- the shim (14) has an upper face (15) inclined relative to the upper face (16) of the board (1). This inclination corresponds in certain cases to a particular natural position preferred by the surfer because it allows a flexion of the user's leg.
- the height H used for the calculation is the distance between the surface (16) and the lowest end of the shoe-binding assembly.
- the wedge can be produced in several parts of different nature and / or dimensions, as illustrated in FIG. 6.
- the portion (31) in contact with the board is a stud of reduced bearing surface, making it possible to reduce the mass of the whole.
- a plate (30) capable of receiving the fixing.
- the height H to be taken into account is the cumulative height of the stud (31) and plate (30) assembly.
- the characteristic wedges of the invention can be made of any material conventionally used in the field of surfing, in particular wood, metal alloys, composite materials and plastics.
- shim 14,31
- a layer of viscoelastic material to absorb the vibrations generated by surfing. It will be noted that these vibrations appear more easily in an aggressive practice of surfing, with tight turns.
- the surf according to the invention combines the possibility of using a narrow surf (160 mm instead of the 260 mm conventionally used in the narrowest median zone), therefore having a good ability to chain rapid changes of edge while maintaining an optimal foot position, that is to say either the rear foot being practically perpendicular to the longitudinal axis of the surf in the case where the feet are side by side, or the feet slightly oriented transversely in the case where these are substantially one behind the other.

Abstract
Description
L'invention constitue un perfectionnement des planches de glisse utilisées de façon unique, et concerne plus précisément les cales de réhaussement des fixations montées sur de telles planches.The invention constitutes an improvement of the gliding boards used in a unique manner, and more specifically relates to the shims for raising the bindings mounted on such boards.
Les techniques de pratique du surf de neige sont en cours d'évolution. Après une période pendant laquelle on utilisait le surf surtout dans la neige poudreuse et en faisant des virages relativement larges, la pratique du slalom dans de la neige damée, avec des virages rapprochés et rapides attire de plus en plus de surfeurs. Les carres sont donc plus fréquemment mises en action, avec des angles d'inclinaison de la planche plus importants.Snowboarding techniques are being developed. After a period during which we used surfing mainly in powder snow and making relatively wide turns, the practice of slalom in groomed snow, with close and fast turns attracts more and more surfers. The edges are therefore more frequently put into action, with greater angles of inclination of the board.
Pour ce mode d'utilisation, en ce qui concerne la forme des surfs, la tendance actuelle est donc de rendre de plus en plus étroite la zone médiane de la planche. Cela permet de diminuer le temps de bascule d'une carre à l'autre, d'augmenter l'aptitude à enchaîner des virages serrés et donc d'accélérer la vitesse en slalom. En outre, on augmente ainsi la puissance d'accrochage de la carre.For this mode of use, with regard to the shape of the surfboards, the current trend is therefore to make the median zone of the board more and more narrow. This makes it possible to reduce the rocking time from one edge to another, to increase the ability to chain tight turns and therefore to accelerate speed in slalom. In addition, this increases the catching power of the edge.
Or, la largeur du surf est principalement conditionnée par la longueur de la chaussure du surfeur. L'inconvénient observé sur les surfs existants est que si les extrémités de la chaussure débordent, lors de l'inclinaison de la planche, elles risquent de toucher la neige, donc de provoquer la chute du surfeur.However, the width of the surf is mainly conditioned by the length of the surfer's shoe. The disadvantage observed on existing surfboards is that if the ends of the shoe overflow, during the inclination of the board, they risk touching the snow, therefore causing the surfer to fall.
Pour utiliser des planches performantes donc relativement étroites, certains surfeurs sont contraints de modifier leur position de pieds, notamment l'angle de la fixation avec l'axe longitudinal du surf, de manière à éviter que les extrémités des chaussures n'arrivent à toucher la neige. Cette adaptation conduit à une position qui n'est pas naturelle pour le surfeur et qui ne permet donc pas une pratique optimale.To use high performance boards which are therefore relatively narrow, some surfers are forced to modify their feet position, in particular the angle of the binding with the longitudinal axis of the board, so as to prevent the ends of the shoes from touching the snow. This adaptation leads to a position which is not natural for the surfer and which therefore does not allow optimal practice.
Pour donner un ordre de grandeur, les surfs traditionnels ont une zone centrale de 260 mm de large environ, tandis que les surfs performants ont une zone étroite d'environ 160 mm de large.To give an order of magnitude, traditional surfboards have a central area of about 260 mm wide, while high-performance surfboards have a narrow area of around 160 mm wide.
Par ailleurs, on connaît également une autre pratique de glisse à l'aide d'une planche unique dans laquelle les pieds sont disposés l'un derrière l'autre sur une planche étroite, telle que notamment illustrée dans le brevet US 4 867 470. La position des pieds disposés sensiblement l'un derrière l'autre permet d'utiliser des planches plus étroites, d'une largeur comprise généralement entre 100 et 200 millimètres, pour lesquels les risques de contact de la chaussure avec la neige sont d'autant plus importants.Furthermore, another sliding practice is also known using a single board in which the feet are arranged one behind the other on a narrow board, such as in particular illustrated in US Pat. No. 4,867,470. The position of the feet arranged substantially one behind the other makes it possible to use narrower boards, with a width generally between 100 and 200 millimeters, for which the risks of contact of the boot with snow are all the more more important.
L'objectif de l'invention est de permettre l'utilisation d'une planche de glisse unique à zone médiane étroite en évitant l'accrochage des fixations ou de la chaussure sur la neige, et ceci que ce soit dans le cas où les pieds sont sensiblement disposés en travers de la planche ou dans le cas où ceux-ci sont disposés sensiblement selon l'axe longitudinal avec une planche encore plus étroite.The objective of the invention is to allow the use of a single gliding board with a narrow median zone while avoiding the attachment of the bindings or of the boot on the snow, and this either in the case where the feet are substantially arranged across the board or in the case where these are arranged substantially along the longitudinal axis with an even narrower board.
Pour résoudre ce problème, la planche de glisse unique conforme à l'invention est du type comprenant
- une planche d'épaisseur maximale (E) et de largeur minimale (L) dans la zone centrale et présentant un axe longitudinal correspondant sensiblement à son axe de déplacement;
- deux fixations respectivement avant et arrière comportant une platine d'épaisseur (F), présentant chacune un axe longitudinal médian qui forment avec l'axe longitudinal de la planche des angles respectifs α et β, ces fixations étant destinées à recevoir les chaussures de l'utilisateur pour former des ensembles chaussures-fixations,
- des cales de rehaussement des fixations par rapport à la planche, de hauteur H.
- a board of maximum thickness (E) and minimum width (L) in the central zone and having a longitudinal axis corresponding substantially to its axis of movement;
- two bindings respectively front and rear comprising a thickness plate (F), each having a median longitudinal axis which form with the longitudinal axis of the board respective angles α and β, these bindings being intended to receive the shoes of the user to form shoe-binding assemblies,
- wedges for raising the bindings relative to the board, height H.
Elle se caractérise en ce que au moins un ensemble chaussure-fixation déborde, au moins d'un coté de la planche d'une distance (D), et en ce que la hauteur H de la cale vérifie la formule suivante:
De cette manière, on surélève la fixation d'une hauteur suffisante pour obtenir un angle d'accrochage maximal limitant les risques de contact de l'ensemble chaussure-fixation avec la neige, c'est-à-dire inférieur à l'angle de décrochage.In this way, the binding is raised by a sufficient height to obtain a maximum hooking angle limiting the risks of contact of the shoe-binding assembly with the snow, that is to say less than the angle of dropout.
On rappelle que l'angle d'accrochage est l'angle formé par le plan de la surface inférieure de la planche et la surface de la neige lorsque la planche est inclinée autour de l'arête inférieure de la carre, de telle façon que l'extrémité de l'ensemble chaussure-fixation débordant de la planche, touche la neige.Remember that the attachment angle is the angle formed by the plane of the bottom surface of the board and the surface of the snow when the board is tilted around the bottom edge of the edge, so that the the end of the shoe-binding assembly extending beyond the board, touches the snow.
L'angle d'accrochage sur une planche de glisse conforme à l'invention est donc égal ou supérieur à 45°.The attachment angle on a gliding board according to the invention is therefore equal to or greater than 45 °.
Dans la pratique de la glisse sur une planche étroite, jusqu'à présent, l'utilisateur est obligé de réduire au maximum l'angle que fait son pied avec l'axe longitudinal de la planche afin d'éviter tout débordement latéral, ce qui peut s'avérer inconfortable voire instable.In the practice of sliding on a narrow board, until now, the user is obliged to minimize the angle made by his foot with the longitudinal axis of the board in order to avoid any lateral overflow, which may be uncomfortable or even unstable.
L'utilisation d'une cale conforme à l'invention permet au surfeur de retrouver une position de pieds plus naturelle, donc plus efficace, en conservant un angle de décrochage satisfaisant.The use of a wedge according to the invention allows the surfer to find a more natural position of feet, therefore more effective, while maintaining a satisfactory stall angle.
Pour améliorer encore la stabilité et la capacité d'enchaînement des virages, on préférera un angle d'accrochage supérieur à 60°, c'est-à-dire une cale dont la hauteur H vérifie la formule suivante:
Dans une première forme de réalisation, la surface supérieure de la cale est parallèle à la surface supérieure de la planche.In a first embodiment, the upper surface of the wedge is parallel to the upper surface of the board.
Dans une variante de réalisation, la surface supérieure de la cale est inclinée vers l'avant de la chaussure par rapport à la face supérieure de la planche. En d'autres termes, la cale surélève plus l'arrière que l'avant de la chaussure afin de correspondre à la position naturelle de l'utilisateur. Dans ce cas, la hauteur H intervenant dans les formules est, bien entendu, la hauteur de la cale au niveau du point le plus bas de l'ensemble chaussure-fixation.In an alternative embodiment, the upper surface of the wedge is inclined towards the front of the shoe relative to the upper face of the board. In other words, the wedge raises the rear more than the front of the shoe to correspond to the natural position of the user. In this case, the height H used in the formulas is, of course, the height of the wedge at the lowest point of the shoe-binding assembly.
En pratique, la cale est en un matériau choisi parmi le groupe contenant le bois, les alliages métalliques, les matériaux composites, et les matières plastiques.In practice, the wedge is made of a material chosen from the group containing wood, metal alloys, composite materials, and plastics.
Avantageusement, la cale présente également une couche en matériau viscoélastique qui permet d'absorber une partie des vibrations générées par la planche.Advantageously, the wedge also has a layer of viscoelastic material which makes it possible to absorb part of the vibrations generated by the board.
Dans une variante permettant l'allégement du poids de la planche de glisse et la personnalisation du rehaussement, la cale est réalisée en deux parties distinctes localisées respectivement dans la zone antérieure et dans la zone postérieure de la chaussure.In a variant allowing the weight of the gliding board to be lightened and the heightening to be personalized, the wedge is produced in two distinct parts located respectively in the anterior zone and in the posterior zone of the boot.
Dans une forme plus sophistiquée de l'invention, la cale présente des évidements aptes à l'alléger.In a more sophisticated form of the invention, the wedge has recesses capable of lightening it.
Toujours dans le but d'obtenir une cale aussi légère que possible, celle-ci peut être composée de deux parties à savoir un plot de largeur réduite sur lequel repose un plateau de dimensions compatibles à la solidarisation de la fixation. Dans ce cas, la hauteur H à prendre en compte est la distance entre le dessus de la planche de surf et la base de l'ensemble chaussure-fixation.Still with the aim of obtaining a shim as light as possible, this can be composed of two parts, namely a stud of reduced width on which rests a plate of dimensions compatible with the fixing of the binding. In this case, the height H to be taken into account is the distance between the top of the surfboard and the base of the shoe-binding assembly.
La manière de réaliser l'invention ainsi que les avantages qui en découlent, ressortiront bien de la description du mode de réalisation qui suit, à l'appui des figures annexées.The manner of carrying out the invention as well as the advantages which ensue therefrom will emerge clearly from the description of the embodiment which follows, with the support of the appended figures.
La figure 1 est une vue de dessus schématique d'un surf sur lequel les pieds sont sensiblement en travers de l'axe longitudinal de la planche.Figure 1 is a schematic top view of a board on which the feet are substantially across the longitudinal axis of the board.
La figure 2 est une vue de dessus d'une planche plus étroite dans laquelle les pieds sont positionnés sensiblement selon l'axe longitudinal de la planche.Figure 2 is a top view of a narrower board in which the feet are positioned substantially along the longitudinal axis of the board.
La figure 3 est une coupe selon le plan longitudinal d'une chaussure, de l'ensemble planche-cale-fixation, montrant les grandeurs caractéristiques de l'invention.Figure 3 is a section along the longitudinal plane of a shoe, of the board-wedge-binding assembly, showing the characteristic quantities of the invention.
La figure 4 illustre une variante de l'invention montrée à la figure 3 présentant une cale inclinée.Figure 4 illustrates a variant of the invention shown in Figure 3 having an inclined wedge.
Les figures 5 et 6 sont des coupes également selon le plan longitudinal d'une chaussure de l'invention pour laquelle la cale est en deux parties, respectivement juxtaposées et superposées.Figures 5 and 6 are sections also along the longitudinal plane of a shoe of the invention for which the wedge is in two parts, respectively juxtaposed and superimposed.
Comme on le voit aux figures 1 et 2, la planche de glisse unique est constituée d'une planche (1) de forme générale allongée, symétrique par rapport à un plan longitudinal médian (2). Bien entendu, l'invention concerne également les surfs comportant des extrémités et/ou des lignes de cotes asymétriques.As seen in Figures 1 and 2, the single gliding board consists of a board (1) of generally elongated shape, symmetrical with respect to a median longitudinal plane (2). Of course, the invention also relates to surfboards having ends and / or asymmetrical dimension lines.
Cette planche présente un resserrement dans sa zone médiane (3). La largeur L de cette zone est un facteur important, car comme déjà dit, la tendance actuelle est de fabriquer des surf de plus en plus étroits.This board has a tightening in its middle zone (3). The width L of this area is an important factor, because as already said, the current trend is to manufacture increasingly narrow surfboards.
De manière connue, la planche reçoit deux fixations (4,5) qui sont disposées de manière inclinée par rapport à l'axe longitudinal de la planche. Pour tenir compte de la position naturelle du surfeur, ces fixations (4,5) sont placés au travers de l'axe longitudinal (2). Selon les utilisateurs et le type de pratique, les angles d'inclinaison sont différents entre le pied avant et le pied arrière. Typiquement dans la pratique avec une planche telle qu'illustrée à la figure 1, l'axe (40) du pied avant (4) est orienté d'un angle (α) compris entre 20° et 90° par rapport à l'axe longitudinal (2), la pointe du pied étant bien entendue dirigée vers l'avant de cette position. De son coté, l'angle (β) que forme l'axe (50) du pied arrière (5) avec l'axe longitudinal (2), est compris entre 45° et 110°, c'est-à-dire que la pointe du pied peut être légèrement dirigée soit vers l'avant soit vers l'arrière du surf, à la convenance de l'utilisateur. La position la plus communément adoptée correspond à 45° pour α et à 80° pour β.In known manner, the board receives two fixings (4,5) which are arranged in an inclined manner with respect to the longitudinal axis of the board. To take into account the natural position of the surfer, these bindings (4,5) are placed across the longitudinal axis (2). Depending on the users and the type of practice, the angles of inclination are different between the front foot and the rear foot. Typically in practice with a board as illustrated in Figure 1, the axis (40) of the front leg (4) is oriented at an angle (α) between 20 ° and 90 ° relative to the axis longitudinal (2), the point of the foot being clearly heard directed towards the front of this position. For its part, the angle (β) formed by the axis (50) of the rear leg (5) with the longitudinal axis (2), is between 45 ° and 110 °, that is to say that the tip of the foot can be slightly directed either towards the front or towards the rear of the board, at the convenience of the user. The most commonly adopted position corresponds to 45 ° for α and 80 ° for β.
Parallèlement, dans la pratique avec une planche telle qu'illustrée à la figure 2, dans laquelle les pieds sont sensiblement l'un derrière l'autre, et où la planche est relativement plus étroite, les axes (40, 50) des pieds avant (4) et arrière (5) sont orientés d'un angle (α, β) compris entre 0 et 20° par rapport à l'axe longitudinal (2) de la planche.In parallel, in practice with a board as illustrated in FIG. 2, in which the feet are substantially one behind the other, and where the board is relatively narrower, the axes (40, 50) of the front feet (4) and rear (5) are oriented at an angle (α, β) between 0 and 20 ° relative to the longitudinal axis (2) of the board.
La chaussure (6,7) et la fixation proprement dite (8,9) forment un ensemble (4,5) dont la longueur ou la largeur dépasse la largeur de la planche, notamment avec la nouvelle tendance de surfs étroits.The shoe (6.7) and the binding itself (8.9) form an assembly (4.5) whose length or width exceeds the width of the board, in particular with the new trend of narrow surfboards.
La différence entre la longueur de l'ensemble chaussure-fixation et la largeur du surf à l'emplacement de cette fixation, permet de déterminer la portion de l'ensemble chaussure-fixation qui se trouve en surplomb à l'extérieur de la planche, et qui donc risque d'accrocher lors de virages serrés.The difference between the length of the shoe-binding assembly and the width of the board at the location of this binding, makes it possible to determine the portion of the shoe-binding assembly which is overhanging outside the board, and which therefore risks catching on tight turns.
Bien évidemment, sur un même surf, cette partie en surplomb (D) varie en fonction de la position des fixations et de leur orientation par rapport au plan longitudinal de la planche.Obviously, on the same board, this overhanging part (D) varies according to the position of the bindings and their orientation relative to the longitudinal plane of the board.
Comme on le voit à la figure 3, l'invention consiste à surélever la fixation (8,9) grâce à une cale (14) de façon à augmenter la valeur de l'angle Ω qui conditionne la limite d'inclinaison de la planche avant l'accrochage.As can be seen in FIG. 3, the invention consists in raising the fixing (8,9) by means of a wedge (14) so as to increase the value of the angle Ω which conditions the limit of inclination of the board before hanging.
Cet angle Ω a pour sommet l'arête (10) de la carre (11). Il est mesuré entre le plan (12) de la surface inférieure de la planche (1) et le plan (13) tangent à l'ensemble chaussure-fixation (4,5). Cet angle correspond à la limite d'inclinaison que peut prendre la planche lors de virages serrés, sans que la fixation ne touche la neige et ne provoque donc la chute.This angle Ω is at the top of the edge (10) of the edge (11). It is measured between the plane (12) of the lower surface of the board (1) and the plane (13) tangent to the shoe-binding assembly (4,5). This angle corresponds to the inclination limit that the board can take during tight turns, without the binding touching the snow and therefore causing the fall.
Conformément à l'invention, cet angle est choisi supérieur à 45°, et même de préférence à 60°, ce qui implique une hauteur minimale à la cale de rehaussement (14), cette hauteur étant déterminée en fonction des paramètres caractéristiques E, F et D repérables sur la figure 3 et dont la définition est rappelée ci-après.
- E : correspond à l'épaisseur de la planche au niveau des axes (40,50) des ensembles chaussure-fixation (4,5).
- F : est l'épaisseur de la platine de fixation, c'est-à-dire la distance entre la base de la semelle de la chaussure et la base de la fixation.
- D : mesure la partie de l'ensemble chaussure-fixation débordant de la largeur de la planche, c'est-à-dire la distance entre l'arête de la carre et la projection dans le plan de la surface inférieure de la planche du point le plus extérieur de l'ensemble chaussure fixation.
- E: corresponds to the thickness of the board at the axes (40.50) of the shoe-binding assemblies (4.5).
- F: is the thickness of the fixing plate, that is to say the distance between the base of the sole of the shoe and the base of the binding.
- D: measures the part of the shoe-binding assembly extending beyond the width of the board, that is to say the distance between the edge of the edge and the projection in the plane of the bottom surface of the board of outermost point of the shoe attachment assembly.
Bien entendu, les grandeurs E, F et D sont exprimées dans la même unité de longueur, par exemple en millimètres.Of course, the magnitudes E, F and D are expressed in the same unit of length, for example in millimeters.
Dans une variante illustrée à la figure 4, la cale (14) présente une face supérieure (15) inclinée par rapport à la face supérieure (16) de la planche (1). Cette inclinaison correspond dans certains cas à une position naturelle particulière préférée du surfeur car elle permet une flexion de la jambe de l'utilisateur. Dans ce cas, la hauteur H utilisée pour le calcul est la distance entre la surface (16) et l'extrémité la plus basse de l'ensemble chaussure-fixation.In a variant illustrated in FIG. 4, the shim (14) has an upper face (15) inclined relative to the upper face (16) of the board (1). This inclination corresponds in certain cases to a particular natural position preferred by the surfer because it allows a flexion of the user's leg. In this case, the height H used for the calculation is the distance between the surface (16) and the lowest end of the shoe-binding assembly.
Pour faciliter la fabrication et le montage, il est possible de rehausser l'avant (20) et l'arrière (21) de la fixation au moyen de deux cales indépendantes (22,23) (cf. fig.5). Dans ce cas, on peut obtenir une inclinaison analogue à celle de la variante précédente en choisissant des cales (22,23) de hauteurs différentes.To facilitate manufacture and assembly, it is possible to raise the front (20) and the rear (21) of the binding by means of two independent shims (22,23) (see fig. 5). In this case, an inclination similar to that of the previous variant can be obtained by choosing shims (22, 23) of different heights.
Dans le même esprit, on peut réaliser la cale en plusieurs parties de nature et/ou de dimensions différentes, comme illustré à la figure 6. La portion (31) au contact de la planche est un plot de surface portante réduite, permettant de réduire la masse de l'ensemble. Au dessus de ce plot repose un plateau (30) apte à recevoir la fixation. Dans ce cas de figure, la hauteur H à prendre en compte est la hauteur cumulée de l'ensemble plot (31) et plateau (30).In the same spirit, the wedge can be produced in several parts of different nature and / or dimensions, as illustrated in FIG. 6. The portion (31) in contact with the board is a stud of reduced bearing surface, making it possible to reduce the mass of the whole. Above this stud rests a plate (30) capable of receiving the fixing. In this case, the height H to be taken into account is the cumulative height of the stud (31) and plate (30) assembly.
Les cales caractéristiques de l'invention peuvent être réalisées en tous matériaux classiquement utilisés dans le domaine du surf, notamment le bois, les alliages métalliques, les matériaux composites et les matières plastiques.The characteristic wedges of the invention can be made of any material conventionally used in the field of surfing, in particular wood, metal alloys, composite materials and plastics.
Dans une forme plus sophistiquée, on peut adjoindre à la cale (14,31) une couche de matériau viscoélastique pour absorber les vibrations générées par le surf. On notera que ces vibrations apparaissent plus facilement dans une pratique agressive du surf, avec des virages serrés.In a more sophisticated form, one can add to the shim (14,31) a layer of viscoelastic material to absorb the vibrations generated by surfing. It will be noted that these vibrations appear more easily in an aggressive practice of surfing, with tight turns.
Il ressort clairement de la description qui précède que le surf conforme à l'invention combine la possibilité d'utiliser un surf étroit (160 mm au lieu des 260 mm classiquement utilisés dans la zone médiane la plus étroite), ayant donc une bonne aptitude à enchaîner des changements de carre rapides tout en conservant une position de pieds optimale, c'est-à-dire soit le pied arrière étant pratiquement perpendiculaire à l'axe longitudinal du surf dans le cas où les pieds sont côte à côte, soit les pieds légèrement orientés transversalement dans le cas où ceux-ci sont sensiblement l'un derrière l'autre.It is clear from the above description that the surf according to the invention combines the possibility of using a narrow surf (160 mm instead of the 260 mm conventionally used in the narrowest median zone), therefore having a good ability to chain rapid changes of edge while maintaining an optimal foot position, that is to say either the rear foot being practically perpendicular to the longitudinal axis of the surf in the case where the feet are side by side, or the feet slightly oriented transversely in the case where these are substantially one behind the other.
