Description

La présente invention a pour objet un surf à neige.The present invention relates to snowboarding.

Un surf est constitué par une planche possédant la structure générale d'un ski, c'est-à-dire comportant une spatule, une zone patin et un talon, la semelle étant délimitée latéralement sur la face inférieure du surf par deux carres métalliques. Comme sur un ski les lignes de cotes, c'est-à-dire l'incurvation latérale des carres peut varier, en fonction des caractéristiques que doit comporter le surf. Lorsque les carres sont incurvées pour fournir une planche plus étroite en son milieu qu'à ses extrémités, un surf est dit posséder un profil en forme de "taille de guêpe". Plus la taille de guêpe est marquée, plus le déclenchement d'un virage est facile. Au contraire, une taille de guêpe moins marquée rend le déclenchement des virages plus difficile, mais favorise la conduite du surf sur neige dure à grande vitesse.A board is made up of a board having the general structure of a ski, that is to say comprising a tip, a skate area and a heel, the sole being delimited laterally on the underside of the board by two metal edges. As on a ski the dimension lines, that is to say the lateral curvature of the edges can vary, according to the characteristics which the surfing must include. When the edges are curved to provide a narrower board in the middle than at its ends, a board is said to have a profile in the shape of an "wasp waist". The larger the wasp size, the easier it is to initiate a turn. On the contrary, a smaller wasp size makes it more difficult to initiate turns, but favors the conduct of surfing on hard snow at high speed.

Le document DE-A-2924023 décrit un monoski comportant une partie inférieure destinée au guidage sur la neige, de largeur inférieure à la partie supérieure, qui sert au montage des fixations et qui présente des chants incurvés en direction de l'axe médian longitudinal dans la zone de patin.The document DE-A-2924023 describes a monoski comprising a lower part intended for guiding on snow, of width less than the upper part, which is used for mounting the bindings and which has curved edges in the direction of the longitudinal median axis in the skate area.

Sur un surf, les deux pieds de l'utilisateur sont fixés de façon décalée longitudinalement l'un par rapport à l'autre. Si, à l'origine, les pieds étaient fixés parallèlement l'un à l'autre et perpendiculairement à l'axe du surf, les deux pieds sont maintenant légèrement tournés vers l'avant, et sont divergents vers l'avant afin de respecter la position naturelle des jambes d'un individu. Si cette position améliore le confort et les capacités d'évolution, elle présente l'inconvénient, dans le cas d'un surf à taille de guêpe assez marquée, que le centre de gravité de l'utilisateur passe, lors d'une prise de carre vers l'avant, en avant de la partie la plus incurvée de la ligne de cote, ou lors d'une prise de carre vers l'arrière, en arrière de la partie la plus incurvée de la ligne de cote. Il en résulte que l'accrochage de la carre considérée sur la neige ne se fait pas de façon uniforme, le talon n'étant pas assez chargé dans le premier cas, alors que la spatule n'est pas assez chargée dans le second cas. C'est pour cette raison que la plupart des surfs ne présentent qu'un profil en taille de guêpe peu marqué.On a board, the user's two feet are fixed longitudinally offset relative to each other. If, originally, the feet were fixed parallel to each other and perpendicular to the axis of the surf, the two feet are now slightly turned forward, and diverging forward to respect the natural position of an individual's legs. If this position improves comfort and ability to evolve, it has the disadvantage, in the case of a wasp-sized surf fairly marked, that the center of gravity of the user passes, when taking edge forwards, in front of the most curved part of the dimension line, or when taking an edge backwards, behind the most curved part of the dimension line. It follows that the attachment of the edge considered on the snow is not done uniformly, the heel is not sufficiently loaded in the first case, while the tip is not sufficiently loaded in the second case. It is for this reason that most surfboards have only a slightly marked wasp profile.

Une autre difficulté que rencontrent les débutants dans la pratique de surf réside dans le déclenchement des virages. En effet, les carres se trouvant au-delà des extrémités des pieds de l'utilisateur, il faut donner une impulsion importante pour incliner fortement le surf, afin de réaliser une prise de carre.Another difficulty encountered by beginners in the practice of surfing lies in the initiation of turns. Indeed, the edges being beyond the ends of the feet of the user, it is necessary to give an important impulse to strongly incline the surfing, in order to carry out an edge grip.

La présente invention vise à remédier à ces inconvénients.The present invention aims to remedy these drawbacks.

A cet effet, le surf qu'elle concerne, du type comportant un profil en taille de guêpe, c'est-à-dire dont les lignes de cote sont incurvées en direction de l'axe médian longitudinal du surf dans la zone de patin de celui-ci, est caractérisé en ce que les fixations forment chacune un angle non nul avec une ligne perpendiculaire à l'axe longitudinal du surf, et en ce que les deux lignes de cote sont décalées longitudinalement l'une par rapport à l'autre et sont positionnées de telle sorte que le point le plus incurvé de chaque ligne de cote se trouve situé sur l'axe de symétrie des axes passant par les deux fixations.To this end, the surf it relates to, of the type comprising a wasp-shaped profile, that is to say the dimension lines of which are curved in the direction of the longitudinal median axis of the surf in the skate area of it, is characterized in that the fixings each form a non-zero angle with a line perpendicular to the longitudinal axis of the surf, and in that the two dimension lines are offset longitudinally one relative to the other and are positioned so that the most curved point of each dimension line is located on the axis of symmetry of the axes passing through the two fixings.

Il résulte de cette structure que, quel que soit l'appui avant ou arrière de l'utilisateur sur l'une ou l'autre carre, son centre de gravité passe par le point d'incurvation maximale de celle-ci, ce qui assure un parfait équilibre au surf, qui n'est ni survireur ni sousvireur.It follows from this structure that, whatever the front or rear support of the user on one or the other edge, its center of gravity passes through the point of maximum curvature thereof, which ensures a perfect balance in surfing, which is neither oversteer nor understeer.

Avantageusement, le bord arrière délimitant le talon est incliné par rapport à la perpendiculaire à l'axe longitudinal du ski, le bord longitudinal situé du côté de l'arrière des fixations étant plus long que le bord longitudinal situé du côté de l'avant des fixations, d'une valeur égale au décalage des lignes de cote.Advantageously, the rear edge delimiting the heel is inclined relative to the perpendicular to the longitudinal axis of the ski, the longitudinal edge located on the side of the rear of the bindings being longer than the longitudinal edge located on the side of the front of the fixings, of a value equal to the offset of the dimension lines.

Outre les caractéristiques fonctionnelles résultant de cette structure, celle-ci procure au surf une esthétique particulière tout à fait agréable.In addition to the functional characteristics resulting from this structure, it gives the surf a particular aesthetic quite pleasant.

En pratique, le décalage longitudinal entre les deux lignes de cote est de l'ordre de 5 cm.In practice, the longitudinal offset between the two dimension lines is of the order of 5 cm.

Conformément à une autre caractéristique de l'invention, ce surf comprend deux paires de carres, à savoir les carres extérieures traditionnelles, et deux autres carres, chacune parallèle à l'une des carres extérieures, disposées plus près que ces dernières de l'axe longitudinal du surf, sous les pieds de l'utilisateur, le plan contenant les carres intérieures étant situé en-dessous du plan contenant les carres extérieures.According to another characteristic of the invention, this surf comprises two pairs of edges, namely the traditional outer edges, and two other edges, each parallel to one of the outer edges, arranged closer than the latter to the axis. longitudinal of the surf, under the feet of the user, the plane containing the interior edges being located below the plane containing the exterior edges.

Les carres intérieures, disposées sous les pieds de l'utilisateur, permettent un basculement et une mise en appui sur une carre plus faciles que traditionnellement, assurant un déclenchement de virage rapide, facilitant la pratique du surf par des débutants, sans nuire à la faculté de déraper facilement. En outre, sur neige damée, il est possible d'amener le surf dans une position d'équilibre dans laquelle celui-ci repose sur ses deux carres situées d'un même côté, avant d'augmenter progressivement l'angulation et d'amener le surf sur la carre extérieure dans des courbes prises à plus grande vitesse.The inner edges, arranged under the feet of the user, allow tilting and pressing on an edge easier than traditionally, ensuring a rapid turn initiation, facilitating the practice of surfing by beginners, without harming the ability to slip easily. In addition, on groomed snow, it is possible to bring the surf in a balanced position in which it rests on its two edges located on the same side, before gradually increasing the angulation and bringing surfing on the outer edge in curves taken at higher speed.

Avantageusement, la distance entre deux carres situées d'un même côté est de l'ordre de 55 mm, tandis que leur décalage vertical est de l'ordre de 7 à 8 mm dans la zone de patin.Advantageously, the distance between two edges located on the same side is of the order of 55 mm, while their vertical offset is around 7 to 8 mm in the skate area.

Selon une autre caractéristique de l'invention, chaque zone de semelle située entre une carre extérieure et une carre intérieure est décalée verticalement par rapport à la partie centrale de la semelle, et est inclinée de l'intérieur vers l'extérieur et de la semelle vers la face supérieure du surf.According to another characteristic of the invention, each sole zone situated between an outer edge and an inner edge is offset vertically with respect to the central part of the sole, and is inclined from the inside towards the outside and of the sole. towards the upper face of the surf.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit en référence au dessin schématique annexé représentant une forme d'exécution de ce surf:

  • Figure 1 en est une vue de dessus:
  • Figures 2 et 3 sont deux vues de la section transversale de ce surf, respectivement, à plat et en virage de grand rayon;
  • Figure 4 en est une vue de côté.
In any case, the invention will be clearly understood with the aid of the following description with reference to the appended schematic drawing representing an embodiment of this surf:
  • Figure 1 is a top view:
  • Figures 2 and 3 are two views of the cross section of this surf, respectively, flat and cornering of large radius;
  • Figure 4 is a side view.

Le surf représenté au dessin et désigné par la référence générale 2 comprend, de façon connue, une spatule 3, une zone de patin 4 et un talon 5.The surfboard shown in the drawing and designated by the general reference 2 comprises, in a known manner, a spatula 3, a skid zone 4 and a heel 5.

Ce surf présente un profil en taille de guêpe, c'est-à-dire comporte des lignes de cotes 6 et 7 présentant une incurvation marquée dans leur partie centrale.This surf has a wasp-shaped profile, that is to say has dimension lines 6 and 7 having a marked curvature in their central part.

Comme montré au dessin, ce surf est équipé, de façon connue, de deux fixations pour les deux pieds de l'utilisateur, désignées par la référence 8 pour la fixation avant, et 9 pour la fixation arrière. Les deux fixations 8 et 9 sont décalées longitudinalement, et forment un angle avec la perpendiculaire à l'axe longitudinal 10 du surf, les axes respectivement 12 et 13 de ces deux fixations 8 et 9 étant légèrement tournés vers l'avant par rapport à la perpendiculaire à l'axe longitudinal 10, et ces deux axes 12 et 13 formant entre eux un angle légèrement ouvert vers l'avant, c'est-à-dire du côté de la ligne de cote 6.As shown in the drawing, this surfboard is equipped, in a known manner, with two fixings for the two feet of the user, designated by the reference 8 for the front fixation, and 9 for the rear fixation. The two bindings 8 and 9 are offset longitudinally, and form an angle with the perpendicular to the longitudinal axis 10 of the surf, the axes respectively 12 and 13 of these two bindings 8 and 9 being slightly turned forward relative to the perpendicular to the longitudinal axis 10, and these two axes 12 and 13 forming between them an angle slightly open towards the front, that is to say on the side of the dimension line 6.

Les deux axes 12 et 13 des deux fixations 8 et 9 sont donc symétriques par rapport à une ligne 14, elle-même inclinée par rapport à la perpendiculaire à l'axe longitudinal 10 du surf.The two axes 12 and 13 of the two fasteners 8 and 9 are therefore symmetrical with respect to a line 14, itself inclined with respect to the perpendicular to the longitudinal axis 10 of the surf.

Comme il ressort de la figure 1, et selon la caractéristique essentielle de l'invention, les deux lignes de cotes 6 et 7 sont décalées longitudinalement l'une par rapport à l'autre, de telle sorte que le point d'incurvation maximale de chaque ligne de cote 6, 7 se trouve situé au point d'intersection de la ligne 14 avec la ligne de cote considérée. En pratique ce décalage longitudinal des deux lignes de cotes est de l'ordre de 5 cm. Compte tenu des différences de positionnement des deux lignes de cotes, le bord arrière 15 délimitant le talon est incliné de l'avant vers l'arrière et de l'extrémité de la ligne de cote 6 vers l'extrémité de la ligne de cote 7.As is apparent from FIG. 1, and according to the essential characteristic of the invention, the two dimension lines 6 and 7 are offset longitudinally with respect to each other, so that the point of maximum curvature of each dimension line 6, 7 is located at the point of intersection of line 14 with the dimension line considered. In practice, this longitudinal offset of the two dimension lines is of the order of 5 cm. Given the differences in positioning of the two dimension lines, the rear edge 15 delimiting the heel is inclined from front to rear and from the end of the dimension line 6 towards the end of the dimension line 7 .

Il résulte de cette caractéristique que, lorsque l'utilisateur prend une prise de carre au niveau de la ligne de cote 6, son centre de gravité passe par le point d'incurvation maximale de cette ligne de cote, de telle sorte que le surf est parfaitement équilibré. De même lorsque l'utilisateur prend une prise de carre sur la carre correspondant à la ligne de cote 7, son sens de gravité passe par le point d'incurvation maximale de cette ligne de cote, de telle sorte que le surf est parfaitement équilibré, ne présentant ni caractère survireur ni caractère sousvireur.It follows from this characteristic that, when the user takes an edge grip at the level of the dimension line 6, his center of gravity passes through the point of maximum curvature of this dimension line, so that the surf is perfectly balanced. Similarly when the user takes an edge grip on the edge corresponding to the dimension line 7, his sense of gravity passes through the point of maximum curvature of this dimension line, so that the surf is perfectly balanced, having neither a survivor nor a subviror character.

Conformément à une autre caractéristique de l'invention, ce surf comprend deux paires de carres, à savoir les carres extérieures traditionnelles 16 et 17 correspondant aux lignes de cotes 6 et 7, et deux carres intérieures 18 et 19, parallèles respectivement aux carres 16 et 17 situées dans un plan en dessous du plan contenant les carres 16 et 17, et situées sous la zone d'appui des pieds de l'utilisateur.In accordance with another characteristic of the invention, this surf comprises two pairs of edges, namely the traditional outer edges 16 and 17 corresponding to the dimension lines 6 and 7, and two inner edges 18 and 19, parallel respectively to the edges 16 and 17 located in a plane below the plane containing the edges 16 and 17, and located under the support area of the feet of the user.

Comme montré au dessin, la semelle comporte une partie centrale 20 et deux parties latérales 22 décalées verticalement vers le haut par rapport à la partie centrale d'une valeur de 7 à 8 mm dans la zone de patin. Quant au décalage latéral entre les deux carres 16,18 et 17,19, il est de l'ordre de 55 mm.As shown in the drawing, the sole has a central part 20 and two lateral parts 22 offset vertically upwards with respect to the central part with a value of 7 to 8 mm in the shoe area. As for the lateral offset between the two edges 16.18 and 17.19, it is of the order of 55 mm.

Il résulte de cette structure que, compte tenu de la localisation des carres 18 et 19 sous les pieds de l'utilisateur, il est facile de faire basculer le surf sur une de ces carres pour amorcer un virage, en trouvant une position d'équilibre stable dans laquelle la carre extérieure correspondante prend également appui sur la neige. Il est aussi possible de dépasser cette position d'équilibre stable sur deux carres pour ne réaliser qu'un appui sur la carre extérieure comme avec un surf traditionnel. Cette structure facilite grandement l'apprentissage du surf, et la conduite de celui-ci sur une neige damée, sans nuire aux capacités de dérapage latéral.It follows from this structure that, given the location of the edges 18 and 19 under the feet of the user, it is easy to tilt the surf on one of these edges to initiate a turn, by finding a position of equilibrium stable in which the corresponding outer edge is also supported on the snow. It is also possible to exceed this stable equilibrium position on two edges so as to only press on the outer edge as with traditional surfing. This structure greatly facilitates the learning of surfing, and driving it on groomed snow, without adversely affecting the sideslip capabilities.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante, en fournissant un surf de conception simple, demeurant parfaitement équilibre lors des virages sur l'une ou l'autre carre, tout en permettant l'exécution de virages de court rayon, grâce à un profil en taille de guêpe pouvant être très marqué, et possèdant une esthétique très agréable.As is apparent from the above, the invention brings a great improvement to the existing technique, by providing a surf of simple design, remaining perfectly balanced during turns on one or the other edge, while allowing execution short radius turns, thanks to a wasp-shaped profile that can be very marked, and has a very pleasant aesthetic.
