Description

La présente invention se rapport à un ski de fond à nervure longitudinale supérieure prévue pour coopérer avec une rainure correspondante de la semelle de la chaussure.The present invention relates to a cross-country ski with an upper longitudinal rib intended to cooperate with a corresponding groove in the sole of the boot.

Dans son brevet FR-A-2.565.114, la Demanderesse a décrit un ski de fond en forme de poutre allongée présentant, au moins dans la zone placée sous le pied, une zone longitudinale nervurée formée par une face supérieure dont la largeur est inférieure à la largeur de la semelle et par deux faces inclinées raccordant cette face supérieure aux deux chants latéraux du ski.In its patent FR-A-2,565,114, the Applicant has described a cross-country ski in the form of an elongated beam having, at least in the zone placed under the foot, a ribbed longitudinal zone formed by an upper face whose width is less to the width of the sole and by two inclined faces connecting this upper face to the two lateral edges of the ski.

Cette nervure longitudinale supérieure est destinée à coopérer avec une rainure complémentaire aménagée sur toute la longueur de la semelle de la chaussure, selon un principe connu du document FR-A-1.435.195.This upper longitudinal rib is intended to cooperate with a complementary groove arranged over the entire length of the sole of the shoe, according to a principle known from document FR-A-1,435,195.

Il est connu de rapporter, sur un ski de fond et dans sa zone de patin, une plaque anti-abrasion apte à protéger la face supérieure du ski des dommages pouvant être causés par des gravillons, ou autres, qui sont incrustés sous la semelle de la chaussure. Ces plaques connues sont d'épaisseur uniforme.It is known to bring back, on a cross-country ski and in its skate area, an abrasion-resistant plate capable of protecting the upper face of the ski from damage which may be caused by gravel, or the like, which are encrusted under the sole of the shoe. These known plates are of uniform thickness.

Les chaussures se fabriquant en grande série, celles-ci sont normalement prévues avec une rainure longitudinale de dimensions transversales standardisées, ce qui évite de prévoir, par exemple, pour la fabrication des semelles de ces chaussures, autant de moules qu'il y a de pointures. En ce qui concerne les skis en revanche, il est difficile de prévoir une nervure identique en dimensions pour des skis, dont les longueurs et largeurs peuvent être très différentes selon le mode de déplacement du skieur et selon la morphologie de celui-ci. Une chaussure de pointure 41 par exemple pourra peut-être convenir pour une personne de petite taille, pour laquelle un ski de 1,70 mètre sera nécessaire, et peut-être aussi pour une personne dont la haute taille nécessitera l'utilisation d'un ski de 2,10 mètres.The shoes being produced in large series, these are normally provided with a longitudinal groove of standardized transverse dimensions, which avoids providing, for example, for the manufacture of the soles of these shoes, as many molds as there are shoe sizes. With regard to skis, on the other hand, it is difficult to provide an identical rib in dimensions for skis, the lengths and widths of which can be very different depending on the mode of movement of the skier and on the morphology thereof. A shoe size 41 for example may be suitable for a small person, for whom a 1.70 meter ski will be necessary, and perhaps also for a person whose high size will require the use of a 2.10 meter ski.

L'invention vise à résoudre cette difficulté en permettant l'adaptation d'une chaussure, de pointure quelconque mais munie d'une rainure de dimensions transversales standardisées, à un ski de fond présentant une nervure supérieure dont la forme et les dimensions peuvent être très variées. Ce résultat est obtenu par le dispositif tel que défini dans la revendication 1.The invention aims to resolve this difficulty by allowing the adaptation of a shoe, any size but provided with a groove of standardized transverse dimensions, to a cross-country ski having an upper rib whose shape and dimensions can be very varied. This result is obtained by the device as defined in claim 1.

L'invention sera bien comprise, et ses avantages et autres caractéristiques ressortiront, au cours de la description suivante de deux exemples non limitatifs de réalisation de ce ski de fond, en référence aux dessins schématiques annexés dans lesquels :

  • Figure 1 est une vue en perspective de la partie centrale de ce ski de fond ;
  • Figure 2 est une vue en coupe transversale selon II-II de figure 1 ;
  • Figure 3 est une vue semblable à figure 2, mais montrant une variante de réalisation.
The invention will be clearly understood, and its advantages and other characteristics will emerge during the following description of two nonlimiting examples of the construction of this cross-country ski, with reference to the appended schematic drawings in which:
  • Figure 1 is a perspective view of the central part of this cross-country ski;
  • Figure 2 is a cross-sectional view along II-II of Figure 1;
  • Figure 3 is a view similar to Figure 2, but showing an alternative embodiment.

En se reportant aux figures 1 et 2, ce ski de fond 1 est du type tel que décrit dans le document FR-A-2.565.114 précité. Il a une forme de poutre allongée qui présente, dans la zone de patin représentée à la figure 1 et située sous la chaussure 2, une nervure longitudinale supérieure 3 formée par une face supérieure 4, dont la largeur est inférieure à la largeur de la semelle 5, et par deux faces inclinées 6 raccordant cette face supérieure 4 aux deux chants latéraux 7 du ski.Referring to Figures 1 and 2, this cross-country ski 1 is of the type as described in the document FR-A-2,565,114 mentioned above. It has an elongated beam shape which has, in the skate area shown in FIG. 1 and located under the shoe 2, an upper longitudinal rib 3 formed by an upper face 4, the width of which is less than the width of the sole. 5, and by two inclined faces 6 connecting this upper face 4 to the two side edges 7 of the ski.

La semelle 8 de la chaussure 2 présente à son tour une rainure longitudinale 9 qui est destinée à chevaucher, en l'encastrant étroitement, la nervure 3 du ski. Afin d'adapter étroitement la rainure 9 à la nervure 3, dont les dimensions sont souvent différentes, une pièce anti-abrasion 10 est rapportée, dans la zone de patin, sur la nervure 3 en fin de fabrication du ski. Cette pièce 10 est donc telle que son profil extérieur 11 correspond au profil de la rainure 9 de la semelle 8, tandis que son profil intérieur 12 correspond au profil de la nervure 3 dans la zone de patin.The sole 8 of the boot 2 in turn has a longitudinal groove 9 which is intended to overlap, by tightly fitting it, the rib 3 of the ski. In order to closely adapt the groove 9 to the rib 3, the dimensions of which are often different, an abrasion-resistant part 10 is attached, in the skid area, to the rib 3 at the end of manufacture of the ski. This part 10 is therefore such that its outer profile 11 corresponds to the profile of the groove 9 of the sole 8, while its inner profile 12 corresponds to the profile of the rib 3 in the skid area.

La pièce 10 est par exemple réalisée en matière thermo-plastique injectée. Elle est avantageusement rapportée sur le ski, en phase de finition de celui-ci, après qu'elle ait été moulée et éventuellement usinée, c'est-à-dire fabriquée, puis décorée. Grâce à elle, une-même chaussure 2, équipée d'une semelle 8 à rainure donnée, peut s'adapter à différents modèles de skis, équipés d'une nervure dont la section droite peut avoir une forme très variée, et s'étendant sur tout ou partie de leur largeur : à titre d'exemple, la figure 3 montre une telle pièce anti-abrasion 10 rapportée sur un ski dont la nervure centrale a une forme rectangulaire.The part 10 is for example made of injected thermo-plastic material. It is advantageously attached to the ski, in the finishing phase thereof, after it has been molded and possibly machined, that is to say manufactured, then decorated. Thanks to her, even shoe 2, equipped with a sole 8 with a given groove, can adapt to different models of skis, equipped with a rib whose cross section can have a very varied shape, and extending over all or part of their width : by way of example, FIG. 3 shows such an abrasion-resistant part 10 attached to a ski, the central rib of which has a rectangular shape.

L'épaisseur de la pièce 10, qui peut être variable dans le sens longitudinal selon la conformation de la nervure 3, dépend aussi de la ligne de cote du ski, de sa largeur, de sa souplesse, et de sa hauteur.The thickness of the piece 10, which can be variable in the longitudinal direction according to the conformation of the rib 3, also depends on the dimension line of the ski, its width, its flexibility, and its height.

L'invention n'est pas limitée aux deux exemples de réalisation qui viennent d'être décrits, et concerne bien au contraire toutes les formes de réalisation équivalentes, l'essentiel étant que la pièce anti-abrasion 10 ait un profil extérieur qui correspond au profil de la rainure de la chaussure, et un profil intérieur qui correspond au profil de la nervure du ski dans la zone de patin située sous la chaussure. En variante par exemple, la pièce anti-abrasion 10 de l'invention peut être constituée de plusieurs parties se succédant, dans la zone de patin prédéfinie, selon l'axe longitudinal du ski.The invention is not limited to the two exemplary embodiments which have just been described, and on the contrary relates to all equivalent embodiments, the main thing being that the abrasion-resistant part 10 has an external profile which corresponds to the profile of the groove of the boot, and an interior profile which corresponds to the profile of the rib of the ski in the skate area located under the boot. In a variant, for example, the abrasion-resistant part 10 of the invention may consist of several successive parts, in the predefined skid zone, along the longitudinal axis of the ski.
