These shells therefore require a different manufacturing mold by size. It is then known to provide two different half-sizes for each shell by being able to integrate two slippers of slightly different volume or with two insoles of different thickness in the same hull, which allows to multiply the possible choices for the skier. Then, the spacing of the shoe attachment device on the ski, between the stop and the heel, is adjusted to the dimension of the outer sole of the ski boot for the practice of skiing.
  • ski equipment rental shops must have series of ski boots of all sizes, to provide customers with a ski boot adapted to their size. Then, when a customer has chosen his shoe, it must be offered a ski to his size: the spacing of the ski fixation device chosen rarely corresponds to the ski boot chosen, since the previous ski hire had often a different shoe size, which requires the adjustment of this spacing to adapt to the chosen ski boot.

Abstract

The ski boot pair has two ski boots (1) whose rigid outer shells (2) are identical, where one of the rigid shells comprises an internally inserted slipper. The slipper comprises a rigid bootboard (5) i.e. zeppa, and side walls, such that the shells of the boots are of different sizes. The slipper has a stiffness equivalent to that of expanded polyurethane in the shell, with a Shore D hardness ranging from 20 to 30. The side walls are extended half way around the perimeter of a foot at a given height or all the way around the perimeter of the foot. An independent claim is also included for a method for manufacturing a pair of ski boots.

Description

L'invention concerne une coque de chaussure de ski et une chaussure de ski en tant que telle comprenant une telle coque. Elle concerne aussi un procédé de fabrication d'une coque de chaussure de ski. Enfin, elle concerne une série de chaussures de ski et un procédé de fabrication d'une telle série.The invention relates to a ski boot shell and a ski boot as such comprising such a shell. It also relates to a method of manufacturing a ski boot shell. Finally, it relates to a series of ski boots and a method of manufacturing such a series.

De manière connue, une chaussure de ski se compose en général d'une coque rigide, obtenue par injection d'un matériau plastique dans un moule de fabrication, sur laquelle on fixe un collier articulé en matériau plastique, obtenu de manière similaire par injection, destiné à couvrir le bas de jambe. Cet ensemble forme une tige de chaussure de ski en matériau plastique de dureté généralement comprise entre 40 et 60 Shore D. Le procédé d'injection de la coque et du collier nécessite des moules de fabrication très coûteux. La coque est destinée à entourer le pied et correspond à une pointure donnée. Elle comprend une semelle rigide externe comprenant des trottoirs avant et arrière normalisés destinés à coopérer avec les mâchoires de respectivement une butée et une talonnière d'un dispositif de fixation de la chaussure sur le ski. Une semelle dite Zeppa est généralement intégrée dans la coque, puis un chausson de confort intérieur dans lequel se trouve généralement une semelle de propreté. Il est connu de prévoir une coque de dimension différente par pointure entière, c'est-à-dire comprenant une longueur différente de sa semelle, entre les deux trottoirs, ainsi que des dimensions globalement différentes pour correspondre à des pieds de pointure différente, selon des volumes normalisés comme selon la norme Mondopoint par exemple. Ces coques nécessitent donc un moule de fabrication différent par pointure. Il est connu ensuite de prévoir deux demi-pointures différentes pour chaque coque en pouvant intégrer deux chaussons de volume légèrement différents ou comprenant deux semelles de propreté d'épaisseur différente dans une même coque, ce qui permet de multiplier les choix possibles pour le skieur. Ensuite, l'écartement du dispositif de fixation de chaussure sur le ski, entre la butée et la talonnière, est réglé à la dimension de la semelle externe de la chaussure de ski pour la pratique du ski.In known manner, a ski boot generally consists of a rigid shell, obtained by injection of a plastic material into a manufacturing mold, on which is fixed a hinged collar of plastic material, similarly obtained by injection, intended to cover the lower leg. This set forms a ski boot shank of plastic material with a hardness generally of between 40 and 60 Shore D. The method of injection of the shell and the collar requires very expensive manufacturing molds. The hull is intended to surround the foot and corresponds to a given size. It comprises an outer rigid sole comprising standardized front and rear sidewalks intended to cooperate with the jaws of respectively an abutment and a heel of a fastening device of the boot on the ski. A so-called Zeppa sole is usually integrated in the shell, then an inner comfort liner in which there is usually a sockliner. It is known to provide a shell of different size by full size, that is to say comprising a different length of its sole, between the two sidewalks, as well as dimensions that are generally different to correspond to feet of different size, according to standardized volumes such as the Mondopoint standard for example. These shells therefore require a different manufacturing mold by size. It is then known to provide two different half-sizes for each shell by being able to integrate two slippers of slightly different volume or with two insoles of different thickness in the same hull, which allows to multiply the possible choices for the skier. Then, the spacing of the shoe attachment device on the ski, between the stop and the heel, is adjusted to the dimension of the outer sole of the ski boot for the practice of skiing.

Cette situation implique une lourdeur dans la gestion des chaussures de ski et des skis, notamment pour les magasins de location de matériel de ski. En effet, ces magasins doivent disposer de séries de chaussures de ski de toutes les pointures, pour mettre à disposition des clients une chaussure de ski adaptée à leur pointure. Ensuite, lorsqu'un client a choisi sa chaussure, il faut lui proposer un ski à sa taille : l'écartement du dispositif de fixation du ski choisi correspond rarement à la chaussure de ski choisie, puisque le précédent loueur du ski avait bien souvent une chaussure de pointure différente, ce qui nécessite le réglage de cet écartement pour l'adapter à la chaussure de ski choisie. Ainsi, les magasins de location de matériel de ski doivent prévoir dans la pratique de nombreuses opérations de réglage, ce qui prend du temps et induit des risques d'erreur, et doivent disposer d'une série de chaussures de toutes les pointures et demi-pointures, ce qui représente un lourd investissement.This situation implies a heaviness in the management of ski boots and skis, especially for ski equipment rental shops. Indeed, these stores must have series of ski boots of all sizes, to provide customers with a ski boot adapted to their size. Then, when a customer has chosen his shoe, it must be offered a ski to his size: the spacing of the ski fixation device chosen rarely corresponds to the ski boot chosen, since the previous ski hire had often a different shoe size, which requires the adjustment of this spacing to adapt to the chosen ski boot. Thus, ski equipment rental shops must provide in practice many adjustment operations, which takes time and induces risks of error, and must have a series of shoes of all sizes and half sizes, which represents a heavy investment.

Pour alléger cette situation, le document US2008196275 propose une solution dans laquelle une série de chaussures s'étendant de la pointure 23 à la pointure 34 n'utilise que trois semelles différentes, soit trois longueurs différentes n'impliquant que trois écartements différents correspondants entre la butée avant et la talonnière d'un dispositif de fixation de chaussure sur une planche de glisse. Ainsi, cette solution est avantageuse en ce qu'elle réduit grandement les nécessités ou les risques d'erreur de réglage du dispositif de fixation de chaussure sur le ski. Pour atteindre ce résultat avantageux, la solution propose deux coques de chaussure de dimension différente pour chaque longueur de semelle, soit au total six coques différentes. Chacune de ces coques reçoit ensuite deux chaussons intérieurs de dimension différente pour former finalement deux pointures différentes, ce qui permet d'atteindre les douze pointures différentes recherchées. Cette solution présente l'inconvénient de nécessiter six moules de fabrication différents pour fabriquer les six coques de dimension différente, ce qui reste coûteux à l'acquisition de la série complète de chaussure. D'autre part, les chaussons permettent de compenser les volumes des coques pour former deux pointures différentes par coque de chaussure : ainsi, la paroi de ces chaussons doit présenter des épaisseurs importantes pour former les plus petites pointures, ce qui nuit à la transmission des efforts du pied vers le ski et réduit la performance globale de la chaussure.To alleviate this situation, the document US2008196275 proposes a solution in which a series of shoes extending from the size 23 to the size 34 uses only three different soles, ie three different lengths involving only three corresponding different spacings between the front stop and the heel of a shoe attachment device on a gliding board. Thus, this solution is advantageous in that it greatly reduces the need or the risk of adjustment error of the shoe attachment device on the ski. For To achieve this advantageous result, the solution offers two shoe shells of different size for each sole length, ie a total of six different shells. Each of these shells then receives two inner slippers of different size to finally form two different sizes, which makes it possible to reach the twelve different sizes sought. This solution has the disadvantage of requiring six different molds to manufacture the six shells of different size, which remains expensive to acquire the complete series of shoes. On the other hand, the slippers make it possible to compensate the volumes of the shells to form two different sizes per shoe shell: thus, the wall of these slippers must have significant thicknesses to form the smallest sizes, which affects the transmission of the shoes. foot effort towards skiing and reduces the overall performance of the shoe.

Le document EP1952711 propose une solution alternative selon une approche similaire dans laquelle une série de chaussures permet d'atteindre douze pointures à partir de quatre longueurs de semelle différentes, et trois coques différentes par longueur de semelle. Cette solution représente le même inconvénient que la solution précédente puisqu'elle nécessite finalement douze moules différents pour fabriquer douze coques différentes.The document EP1952711 proposes an alternative solution according to a similar approach in which a series of shoes makes it possible to reach twelve sizes from four different lengths of sole, and three different shells per sole length. This solution represents the same disadvantage as the previous solution since it finally requires twelve different molds to make twelve different shells.

Ainsi, les solutions précédentes de l'état de la technique permettent de réduire le nombre de combinaisons possibles de longueur de semelles pour réduire les ajustements nécessaires des dispositifs de fixation des chaussures sur un ski. Toutefois, elles exigent toujours un lourd investissement pour l'acquisition de la série complète de chaussures pour couvrir toutes les pointures.Thus, the prior solutions of the state of the art make it possible to reduce the number of possible combinations of sole length to reduce the necessary adjustments of the fastening devices of the shoes on a ski. However, they still require a heavy investment for the acquisition of the full set of shoes to cover all sizes.

Il existe donc un besoin d'une autre solution permettant une réduction du coût d'investissement pour l'obtention d'une série de chaussures de ski.There is therefore a need for an alternative solution to reduce the investment cost for obtaining a series of ski boots.

Selon le concept de l'invention, un sabot intérieur comprenant une semelle et des parois latérales est prévu, apte à une intégration au sein d'une coque rigide classique d'une chaussure de ski de sorte de réduire la pointure définie par cette coque rigide.According to the concept of the invention, an inner shoe comprising a sole and side walls is provided, suitable for integration into a conventional rigid shell of a ski boot so as to reduce the size defined by this rigid shell .

L'invention repose sur une chaussure de ski 1 comprenant les composants habituels et connus, sous une forme telle qu'illustrée sur la figure 1. Elle comprend une coque rigide 2, généralement composée d'un matériau plastique comme du polyuréthane de dureté comprise entre 40 et 60 Shore D ou par tout autre matériau de rigidité équivalente, obtenue par injection, entourant le pied du skieur. Un collier rigide 3, obtenu de même par injection dans un matériau similaire à celui de la coque 2, est monté sur la coque de sorte d'entourer le bas de jambe du skieur. Ces deux éléments rigides, formant une tige, sont dotés d'une échancrure centrale pour permettre un écartement facilitant le chaussage et le déchaussage. Les deux rabats formés de part et d'autre de cette échancrure sont reliés entre eux par des moyens de fixation 4 permettant le rapprochement de ces rabats, la fermeture et le serrage de la tige rigide de la chaussure formée par la réunion de la coque 2 et du collier 3. La coque intègre aussi dans sa partie inférieure une semelle rigide 5 comprenant des trottoirs 6 avant et arrière normalisés sur lesquels viennent se fixer les mâchoires d'un dispositif de fixation de la chaussure sur un ski, non représenté. En variante, cette tige rigide, composée de l'assemblage de la coque 2 et du collier 3, peut présenter toute autre structure, de façon à former un ensemble rigide, dont la rigidité est équivalente à celle d'un polyuréthane de dureté comprise entre 40 et 60 Shore D. Elle peut aussi comprendre quelques sous-parties de surface peu importante en matériau plus rigide ou plus souple. Cette structure peut notamment être obtenue par un procédé à double injection de matériau plastique.The invention is based on a ski boot 1 comprising the usual and known components, in a form as illustrated in FIG. figure 1 . It comprises a rigid shell 2, generally made of a plastic material such as polyurethane hardness between 40 and 60 Shore D or any other material of equivalent rigidity, obtained by injection, surrounding the skier's foot. A rigid collar 3, similarly obtained by injection into a material similar to that of the shell 2, is mounted on the hull so as to surround the lower leg of the skier. These two rigid elements, forming a rod, are provided with a central notch to allow a spacing facilitating donning and heaving. The two flaps formed on either side of this notch are interconnected by fastening means 4 for bringing these flaps together, closing and tightening of the rigid rod of the shoe formed by the meeting of the shell 2 and the collar 3. The shell also incorporates in its lower part a rigid sole 5 comprising standardized front and rear sidewalks 6 on which are fixed the jaws of a fastening device of the boot on a ski, not shown. Alternatively, this rigid rod, consisting of the assembly of the shell 2 and the collar 3, may have any other structure, so as to form a rigid assembly, whose rigidity is equivalent to that of a hardness polyurethane between 40 and 60 Shore D. It can also include some sub-parts of small surface of more rigid or more flexible material. This structure can in particular be obtained by a double injection process of plastic material.

La coque rigide peut intégrer une semelle, comme une semelle couramment appelée Zeppa, fabriquée séparément et insérée dans la coque, pour finaliser la partie inférieure de la coque, selon un procédé bien connu. Cette semelle dite Zeppa présente en général une surface supérieure sensiblement horizontale et une partie inférieure protubérante destinée à se loger dans une rainure longitudinale formée dans la coque, au niveau de la semelle de la chaussure, lors du procédé d'injection. L'avantage de ce procédé de fabrication est de permettre d'obtenir d'une part une coque d'épaisseur relativement constante par injection, et d'autre part la Zeppa par un moulage simple et peu coûteux dont le positionnement au sein de la coque permet finalement de former le volume plus important de matériau nécessaire dans le bas de la coque, tout en obtenant une isolation thermique au niveau de la liaison entre la Zeppa et la coque. Un chausson de confort 10, de volume correspondant au volume intérieur défini par la tige rigide, est ensuite inséré dans cette tige, et destiné à recevoir le pied du skieur. Le chausson de confort épouse au mieux la surface intérieure de la tige rigide de la chaussure pour garantir une bonne transmission des efforts du skieur vers le ski pour obtenir une bonne conduite des skis. Le chausson présente une structure beaucoup plus souple que la tige rigide de la chaussure pour assurer un confort minimal au skieur dont le pied et le bas de jambe sont directement au contact du chausson.The rigid shell may incorporate a sole, such as a sole commonly called Zeppa, manufactured separately and inserted into the shell, to finalize the lower part of the hull, according to a well known method. This so-called Zeppa sole generally has a substantially horizontal upper surface and a protruding lower portion intended to be housed in a longitudinal groove formed in the shell, at the sole of the boot, during the injection process. The advantage of this manufacturing process is that it makes it possible to obtain a relatively constant thickness shell by injection, and on the other hand the Zeppa by a simple and inexpensive molding whose positioning within the shell finally makes it possible to form the larger volume of material needed in the bottom of the shell , while obtaining thermal insulation at the connection between the Zeppa and the hull. A comfort liner 10, of volume corresponding to the internal volume defined by the rigid rod, is then inserted into this rod, and intended to receive the foot of the skier. The comfort boot marries at best the inner surface of the rigid upper of the boot to guarantee a good transmission of the efforts of the skier towards the ski to obtain a good driving of the skis. The liner has a much more flexible structure than the rigid upper of the shoe to provide minimal comfort to the skier whose foot and lower leg are directly in contact with the shoe.

L'invention repose sur l'utilisation d'un composant complémentaire, appelé sabot, destiné à être inséré dans la coque rigide sensiblement conventionnelle d'une chaussure de ski de sorte de réduire la pointure de cette tige. Dans la suite de la description du mode d'exécution de l'invention, le terme pointure sera utilisé pour mentionner des pointures entières, dont les dimensions sont normalisées. Toutefois, le terme de pointure peut intégrer un sens plus large, qui sera explicité plus loin. L'insertion d'un sabot dans une coque injectée, que nous appellerons coque rigide externe, permet de représenter un assemblage formant une coque de plus petit volume intérieur et donc de pointure réduite.The invention is based on the use of a complementary component, called shoe, intended to be inserted into the substantially conventional rigid shell of a ski boot so as to reduce the size of this rod. In the following description of the embodiment of the invention, the term size will be used to mention whole sizes, whose dimensions are normalized. However, the term size can incorporate a broader meaning, which will be explained later. The insertion of a shoe into an injected shell, which we will call an external rigid shell, makes it possible to represent an assembly forming a hull of smaller internal volume and thus reduced size.

Une telle coque obtenue par l'assemblage d'un sabot dans une coque rigide externe reçoit ensuite un chausson de confort habituel, tel que cela va être détaillé par la suite. Cette solution permet à une seule coque injectée, à l'aide d'un seul moule d'injection, d'être utilisée pour plusieurs pointures différentes de chaussure de ski, ce qui représente un gain économique important lors de la fabrication des séries de chaussure, du fait aussi de l'obtention peu coûteuse du sabot.Such a shell obtained by assembling a shoe in an outer rigid shell then receives a usual comfort liner, as will be detailed later. This solution allows a single injected shell, using a single injection mold, to be used for several different sizes of ski boots, which represents a significant economic gain in the manufacture of the shoe series, also because of the inexpensive obtaining of the shoe.

Les figures 2 à 9 illustrent un mode d'exécution de deux sabots selon l'invention. Le sabot 20 des figures 2 à 5 diffère essentiellement du sabot 20' des figures 6 à 9 par l'épaisseur moins importante de ses parois 21. Le volume extérieur des deux sabots reste quasiment identique, puisqu'ils sont destinés à être insérés dans une coque rigide externe identique, obtenue par l'utilisation du même moule de fabrication. Le volume intérieur du sabot 20 est plus grand que celui du sabot 20', les deux volumes et dimensions intérieures de chaque sabot 20, 20' sont définis de sorte de réduire respectivement d'une et deux pointures de chaussure la pointure définie initialement par la coque rigide externe, selon les normes de pointure habituelles. Ainsi, la dimension du premier sabot 20 est prévue pour entraîner la réduction d'une pointure d'une certaine coque rigide, alors que la dimension du second sabot 20' est prévue pour entraîner la réduction de deux pointures de la même coque externe rigide.The Figures 2 to 9 illustrate an embodiment of two shoes according to the invention. The hoof 20 Figures 2 to 5 differs essentially from the shoe 20 ' Figures 6 to 9 by the smaller thickness of its walls 21. The outer volume of the two shoes remains almost identical, since they are intended to be inserted into an identical outer rigid shell, obtained by the use of the same manufacturing mold. The internal volume of the shoe 20 is greater than that of the shoe 20 ', the two inner volumes and dimensions of each shoe 20, 20' are defined so as to reduce respectively by one and two shoe sizes the size initially defined by the outer rigid shell, according to the usual size standards. Thus, the size of the first shoe 20 is provided to cause the reduction of a size of a certain rigid shell, while the size of the second shoe 20 'is provided to cause the reduction of two sizes of the same rigid outer shell.

En appliquant la norme mondopoint, les parois du premier sabot présentent donc une épaisseur totale de sorte de réduire la longueur intérieure de la coque de 10 millimètres, et les parois du second sabot 20' présentent de manière similaire une épaisseur totale de sorte de réduire la longueur intérieure de la coque de 20 millimètres. Ainsi, comme cela est particulièrement visible sur les figures 3 et 7, la paroi antérieure 26, 26' de chaque sabot 20, 20' est choisie plus épaisse que la paroi arrière 27, 27'. Toutefois, les épaisseurs relatives de ces parois pourraient être modifiées, tant que la somme des épaisseurs des parois avant 26, 26' et arrière 27, 27' représentent une valeur d'une ou deux pointures pour respectivement le premier sabot 20 et le second sabot 20'. Les parois latérales de chacun des deux sabots 20, 20' présentent une épaisseur de préférence inférieure à celle des parois frontales et antérieures, qui diminue dans la partie haute pour venir s'arrêter tangentiellement à la paroi intérieure de la coque extérieure, et former un volume intérieur continu et confortable.By applying the norm mondopoint, the walls of the first shoe therefore have a total thickness so as to reduce the inner length of the shell by 10 millimeters, and the walls of the second shoe 20 'similarly have a total thickness so as to reduce the inner length of the shell of 20 mm. Thus, as is particularly visible on figures 3 and 7 , the front wall 26, 26 'of each shoe 20, 20' is chosen thicker than the rear wall 27, 27 '. However, the relative thicknesses of these walls could be modified, as long as the sum of the thicknesses of the front walls 26, 26 'and rear 27, 27' represent a value of one or two sizes for respectively the first shoe 20 and the second shoe 20 '. The side walls of each two shoes 20, 20 'have a thickness preferably lower than that of the front and front walls, which decreases in the upper part to stop tangentially to the inner wall of the outer shell, and form a continuous and comfortable interior volume .

Selon le mode d'exécution représenté sur les figures 2 à 9, le sabot 20, 20' comprend une semelle sensiblement horizontale 25, 25' destinée à recevoir l'appui du pied, et des parois verticales 21, 21' destinées à entourer au moins partiellement le pied du skieur, de sorte de couvrir ses orteils à l'avant et de remonter jusqu'à ses cheville à l'arrière, au-dessus ou au-dessous des malléoles selon la précision voulue. Le sabot 20, 20' comprend de plus deux ouvertures 22, 22' dans sa semelle 25, 25' pour faciliter son positionnement dans une coque, comme cela est illustré en référence avec la figure 11. En variante, tous moyens de centrage ou positionnement pourrait être prévu. Le sabot 20, 20' comprend de plus une échancrure sensiblement verticale 23, 23' au niveau de ses extrémités avant et arrière afin de permettre une flexibilité de ses parois 21, 21' qui facilite son insertion et son retrait dans une coque rigide de chaussure de ski.According to the embodiment shown on the Figures 2 to 9 , the shoe 20, 20 'comprises a substantially horizontal sole 25, 25' intended to receive the support of the foot, and vertical walls 21, 21 'intended to at least partially surround the foot of the skier, so as to cover his toes at the front and up to the ankle at the back, above or below the malleoli to the desired accuracy. The shoe 20, 20 'further comprises two openings 22, 22' in its sole 25, 25 'to facilitate its positioning in a shell, as illustrated with reference to the figure 11 . Alternatively, any centering or positioning means could be provided. The shoe 20, 20 'further comprises a notch substantially vertical 23, 23' at its front and rear ends to allow flexibility of its walls 21, 21 'which facilitates its insertion and removal in a rigid shell shoe ski.

La figure 10 illustre à titre d'exemple la partie inférieure d'une coque rigide 2, qui est tronquée pour faciliter la représentation, qui présente une forme traditionnelle avec une semelle 5 formant des trottoirs 6 à ses extrémités avant et arrière. Selon l'invention, cette semelle comprend des bossages 7 de forme correspondant aux ouvertures 22, 22' des sabots 20, 20'. Ces derniers présentent ainsi une forme adaptée pour un logement dans la coque rigide 2 de la chaussure, de sorte que leurs parois 21 viennent au contact des surfaces intérieures des parois de la coque rigide, selon un assemblage illustré par la figure 5. Le bossage 7 vient occuper l'ouverture 22 de la semelle du sabot 20 de sorte d'assurer la mise en place et le maintien du sabot.The figure 10 illustrates by way of example the lower part of a rigid shell 2, which is truncated to facilitate the representation, which has a traditional shape with a sole 5 forming sidewalks 6 at its front and rear ends. According to the invention, this sole comprises bosses 7 of shape corresponding to the openings 22, 22 'of the shoes 20, 20'. The latter thus have a shape adapted for a housing in the rigid shell 2 of the shoe, so that their walls 21 come into contact with the inner surfaces of the walls of the rigid shell, according to an assembly illustrated by the figure 5 . Boss 7 comes to occupy the opening 22 of the sole of the shoe 20 so as to ensure the establishment and maintenance of the shoe.

Selon l'invention, le sabot 20, 20' est obtenu par un procédé de fabrication simple et économique, à base de polyuréthane expansé pour obtenir un composant semi-rigide, de dureté de l'ordre de 25 Shore D, comprise entre 20 et 30 Shore D, dont les parois latérales comprennent une épaisseur inférieure à 20 millimètres. En variante, le sabot peut être obtenu en caoutchouc, en un matériau recyclé, de sorte d'obtenir une dureté équivalente. Le sabot est de forme simple et en un matériau expansé, qui permet la mise en oeuvre d'un procédé simple, à l'aide d'une faible pression et d'un moule peu coûteux d'autant plus qu'il n'est pas nécessaire d'obtenir une finition propre et précise. Cette solution induit ainsi l'intégration d'un sabot entre la tige externe rigide et le chausson intérieur souple, dont la dureté est intermédiaire entre celle de la tige rigide extérieure 2, 3 de la chaussure et celle du chausson intérieur de confort 10, ce qui représente un bon compromis entre la recherche de la performance finale de la chaussure et son confort.According to the invention, the shoe 20, 20 'is obtained by a simple and economical manufacturing process, based on expanded polyurethane to obtain a semi-rigid component, of hardness of the order of 25 Shore D, between 20 and 30 Shore D, whose side walls comprise a thickness of less than 20 millimeters. Alternatively, the shoe can be made of rubber, a recycled material, so as to obtain an equivalent hardness. The shoe is of simple shape and in an expanded material, which allows the implementation of a simple process, using a low pressure and an inexpensive mold especially as it is no need to get a clean and precise finish. This solution thus induces the integration of a shoe between the rigid outer rod and the soft inner boot, the hardness of which is intermediate between that of the rigid outer rod 2, 3 of the boot and that of the inner comfort boot 10, this which represents a good compromise between the search for the final performance of the shoe and its comfort.

Un tel sabot permet de modifier la pointure d'une coque rigide de chaussure par son intégration au sein de la coque, sans nécessiter la fabrication d'une coque différente, de pointure différente, et donc sans nécessiter le recours à un autre moule de fabrication d'une coque, ce qui réduit grandement les coûts de fabrication. Comme cela a été représenté, plusieurs sabots 20, 20' de même volume extérieur et de volume intérieur différent peuvent permettre, par leur insertion dans une même coque, d'obtenir plusieurs chaussures de pointure différente. Avec cette approche, une même coque peut soit ne recevoir aucun sabot, soit un sabot 20 de première pointure, soit un sabot 20' de seconde pointure, ce qui permet à une même coque rigide d'être utilisée pour former trois coques de chaussure de ski de pointure différente. En variante, plus de deux sabots pourraient être utilisés pour une même coque.Such a shoe makes it possible to modify the size of a rigid boot shell by integrating it into the shell, without requiring the manufacture of a different shell, of different size, and thus without requiring the use of another manufacturing mold. of a hull, which greatly reduces manufacturing costs. As has been shown, several shoes 20, 20 'of the same external volume and different interior volume can allow, by their insertion in the same shell, to obtain several shoes different size. With this approach, the same shell can either receive no shoe, a shoe 20 of the first size, or a shoe 20 'of second size, which allows the same rigid shell to be used to form three ski boot cases of different size. Alternatively, more than two shoes could be used for the same hull.

Toutefois, plus l'épaisseur de la paroi du sabot est importante plus la rigidité globale de la chaussure va diminuer, et plus il sera difficile de réduire le volume initial de la coque de manière homogène, ce qui risque d'entraîner une baisse de la performance de la chaussure et une baisse de son confort. Pour cette raison, le choix de seulement deux sabots dont les parois présentent respectivement des épaisseurs maximales proches de 10 et 20 millimètres représente un bon compromis et une solution optimale.However, the greater the thickness of the hoof wall is greater the overall stiffness of the shoe will decrease, and the more it will be difficult to reduce the initial volume of the hull homogeneously, which may cause a decrease in the shoe performance and a decline in comfort. For this reason, the choice of only two shoes whose walls have respective maximum thicknesses of 10 and 20 millimeters represents a good compromise and an optimal solution.

L'invention porte aussi sur une série de plusieurs chaussures comprenant notamment un nombre de chaussures multiple de trois, c'est-à-dire trois, six, neuf et douze chaussures de ski, pour laquelle une même coque est utilisée pour obtenir trois pointures différentes. Pour cela, pour chaque coque, on peut soit insérer la semelle Zeppa traditionnelle, soit un premier sabot 20, soit un second sabot 20' de plus petit volume intérieur, chaque sabot pouvant être associé ou non à la semelle Zeppa, qui peut éventuellement être intégrée au sabot. Cela permet ainsi d'atteindre trois assemblages équivalant à trois coques de pointure différente à partir d'une seule coque externe rigide fabriquée par injection plastique. Ainsi, il est par exemple possible de fabriquer une série de six chaussures de ski pour les pointures mondopoint de 22 à 27, de 25 à 30, ou de 28 à 33. Pour trois coques injectées prévues, il est possible d'obtenir neuf pointures, par exemple de 22 à 30, la coque la plus petite étant utilisée pour les pointures 22 à 24, la coque intermédiaire pour les pointures 25 à 27, et la plus grande coque pour les pointures 28 à 30. En variante, les neuf pointures peuvent couvrir les tailles de 25 à 33. De même, une série de douze pointures, de 22 à 33, est envisageable, à partir de quatre coques différentes. Dans tous les cas, dans chacune des différentes coques résultantes est inséré un chausson de confort différent, de pointure correspondant à la coque définie par l'éventuel assemblage de la coque externe rigide avec un sabot. Il en résulte qu'aucune coque ne reçoit plusieurs chaussons de pointure différente pour former des pointures entières différentes, ce qui est avantageux. En remarque supplémentaire, un collier injecté est prévu par coque injectée, ce qui permet aussi d'utiliser le même nombre de colliers différents que le nombre de coques et donc un nombre de moules d'injection réduit pour obtenir les différentes chaussures de la série. En variante, il est possible de prévoir des colliers différents pour une même coque, par exemple un collier différent par pointure, ou un même collier pour deux pointures successives, de sorte d'utiliser par exemple trois colliers différents pour une série de chaussures de six pointures et donc pour deux tailles de coque externe. Enfin, les chaussures de pointure différente n'utilisant qu'un nombre réduit de coques différentes, il en ressort qu'une série de chaussure exige un nombre réduit de réglages différents d'un dispositif de fixation de chaussure sur un ski, plus précisément un réglage pour chaque coque externe rigide, ce qui est très avantageux, comme cela a été vu auparavant.The invention also relates to a series of several shoes including a number of shoes multiple of three, that is to say three, six, nine and twelve ski boots, for which the same shell is used to obtain three sizes different. For this, for each shell, one can either insert the traditional Zeppa sole, either a first shoe 20 or a second shoe 20 'of smaller internal volume, each shoe may or may not be associated with the sole Zeppa, which can optionally be integrated into the hoof. This makes it possible to achieve three assemblies equivalent to three shells of different size from a single rigid outer shell manufactured by plastic injection. Thus, it is for example possible to manufacture a series of six ski boots for the mondopoint sizes of 22 to 27, 25 to 30, or 28 to 33. For three injected hulls provided, it is possible to obtain nine sizes , for example from 22 to 30, the smallest hull being used for the sizes 22 to 24, the intermediate hull for the sizes 25 to 27, and the largest hull for the sizes 28 to 30. In a variant, the nine sizes can also cover sizes from 25 to 33. Similarly, a series of twelve sizes, from 22 to 33, is conceivable, starting from four different hulls. In all cases, in each of the different resulting shells is inserted a boot of different comfort, size corresponding to the shell defined by the possible assembly of the rigid outer shell with a shoe. As a result, no shell receives several shoes of different size to form different whole sizes, which is advantageous. As an additional note, an injected collar is provided by injected shell, which also allows to use the same number of different collars as the number of shells and therefore a reduced number of injection molds to obtain the different shoes of the series. Alternatively, it is possible to provide different collars for the same shell, for example a different collar by size, or the same collar for two successive sizes, so for example use three different necklaces for a series of six shoes sizes and therefore for two sizes of outer shell. Lastly, since shoes of different size use only a small number of different shells, it appears that a series of shoes requires a reduced number of different settings of a shoe attachment device on a ski, more specifically a shoe. setting for each rigid outer shell, which is very advantageous, as has been seen before.

Naturellement, l'invention ne se limite pas à l'obtention de la série de chaussures de ski détaillée ci-dessus. Toute autre série pourrait être envisagée, comprenant l'utilisation d'au moins un sabot pour réduire la pointure d'une coque injectée afin d'obtenir deux pointures différentes pour une seule coque injectée, selon l'insertion ou non d'un sabot. D'autre part, le concept de l'invention a été explicité pour la fabrication peu coûteuse d'une série de chaussures, afin d'obtenir des pointures entières différentes, selon la norme de pointure mondopoint. Il est naturellement évident d'exploiter ce même concept pour obtenir des demi-pointures, ou des pointures définies selon toute autre norme. Notamment, le même concept peut servir à former des chaussures différentes, de largeur interne différente, par exemple au niveau de l'articulation métatarsophalangienne, en vue d'utiliser une même coque pour un confort maximal, dans le cas d'une largeur importante, ou pour une performance plus importante, par exemple pour la compétition, dans le cas d'une largeur réduite. Ainsi, le concept de l'invention peut permettre de modifier la dimension intérieure d'une coque dans toutes les directions, pas uniquement sa longueur. Nous entendons donc par pointure le volume intérieur chaussant offert par une chaussure, en considérant toutes les directions.Naturally, the invention is not limited to obtaining the series of ski boots detailed above. Any other series could be envisaged, including the use of at least one shoe to reduce the size of an injected shell to obtain two different sizes for a single injected shell, depending on the insertion or not of a shoe. On the other hand, the concept of the invention has been made explicit for the inexpensive manufacture of a series of shoes, in order to obtain different whole sizes, according to the mondopoint size standard. It is naturally obvious to use this same concept to obtain half sizes, or sizes defined by any other standard. In particular, the same concept can be used to form different shoes of different internal width, for example at the metatarsophalangeal joint, in order to use the same shell for maximum comfort, in the case of a large width, or for a higher performance, for example for the competition, in the case of a reduced width. Thus, the concept of the invention can make it possible to modify the internal dimension of a shell in all directions, not only its length. We therefore mean by size the inside footwear volume offered by a shoe, considering all directions.

L'invention porte aussi sur un procédé de fabrication d'une coque de chaussure de ski, comprenant une étape de fabrication d'une coque rigide externe par injection de matériau plastique rigide et caractérisé en ce qu'il comprend une étape de fabrication d'un sabot puis une étape d'insertion du sabot dans la coque rigide externe. L'étape de fabrication d'un sabot peut consister en une fabrication à partir d'un matériau plastique expansable.The invention also relates to a method of manufacturing a ski boot shell, comprising a step of manufacturing an external rigid shell by injection of rigid plastic material and characterized in that it comprises a step of manufacturing a a shoe and a shoe insertion step in the outer rigid shell. The step of manufacturing a shoe can consist of a manufacturing from an expandable plastic material.

L'invention porte aussi sur un procédé de fabrication d'une série de chaussures de ski, comprenant une étape de fabrication d'au moins deux coques externes 2 identiques par injection de matériau plastique rigide, caractérisé en ce qu'il comprend une étape de fabrication d'un sabot 20 puis une étape d'insertion du sabot 20 dans une coque externe 2 de sorte d'obtenir au moins deux coques de chaussure de ski de pointures différentes et/ou en ce qu'il comprend une étape de fabrication de deux sabots différents 20 ; 20' puis une étape d'insertion de chaque sabot 20 ; 20' dans une coque externe 2 identique de sorte d'obtenir au moins deux coques de chaussure de ski de pointures différentes.The invention also relates to a method of manufacturing a series of ski boots, comprising a step of manufacturing at least two identical outer shells 2 by injection of rigid plastic material, characterized in that it comprises a step of manufacturing a shoe 20 and then a step of inserting the shoe 20 into an outer shell 2 so as to obtain at least two ski boot shells of different sizes and / or in that it comprises a step of manufacturing two different hooves 20; 20 'then an insertion step of each shoe 20; 20 'in an outer shell 2 identical so as to obtain at least two ski boot shells of different sizes.

Le sabot 20, 20' a été illustré à titre d'exemple mais il pourrait présenter d'autres géométries sans sortir du concept de l'invention. Le sabot peut intégrer la structure de la Zeppa traditionnelle et être intégré dans une coque en remplacement de la Zeppa, ou ne pas l'intégrer et être ajouté en plus de la Zeppa dans une coque. D'autre part, ses parois latérales peuvent présenter d'autres formes, des hauteurs plus ou moins importantes, moins régulières sur le pourtour du pied. Toutefois, ces parois latérales sont suffisantes pour permettre la réduction d'au moins une pointure par leur insertion dans une certaine coque, ce qui nécessite une surface minimale répartie sur la périphérie d'un pied de skieur. Les parois latérales du sabot occupent ainsi avantageusement tout le pourtour de la semelle, de sorte de pouvoir entourer entièrement un pied de skieur, ou plus exactement le chausson de confort comprenant le pied d'un skieur. Ce pourtour peut ne pas être totalement continu, des rainures, ouvertures, ou toutes interruptions peuvent être prévues, sans toutefois trop interrompre les parois latérales qui occupent au moins la moitié du pourtour d'un pied pour remplir leur fonction. Le fait de former des parois ajourées peut permettre de réduire le poids et le coût du sabot. De plus, ces parois présentent une hauteur suffisante pour couvrir le côté d'un pied, venir au moins un peu sur le dessus du pied, afin de définir un volume suffisant autour du pied.The shoe 20, 20 'has been illustrated by way of example but it could have other geometries without departing from the concept of the invention. The hoof can integrate the structure of the traditional Zeppa and be integrated in a hull to replace the Zeppa, or not integrate it and be added in addition to the Zeppa in a hull. On the other hand, its side walls may have other shapes, more or less important heights, less regular around the perimeter of the foot. However, these side walls are sufficient to allow the reduction of at least one size by their insertion into a certain shell, which requires a minimal area distributed on the periphery of a skier's foot. The side walls of the shoe advantageously occupy all the periphery of the sole, so as to be able to completely surround a skier's foot, or more precisely the comfort boot comprising the foot of a skier. This circumference may not be completely continuous, grooves, openings, or interruptions may be provided, but without overly interrupting the side walls that occupy at least half of the periphery of a foot to fulfill their function. The fact of forming perforated walls can reduce the weight and cost of the hoof. In addition, these walls have a height sufficient to cover the side of a foot, come at least a little on the top of the foot, to define a sufficient volume around the foot.

Les trois composants de la paroi de la chaussure résultante, c'est-à-dire la paroi de la coque externe, la paroi du sabot, et la paroi du chausson de confort, sont dimensionnés pour venir en appui les uns contre les autres afin d'obtenir une chaussure performante dans la transmission des efforts depuis le pied jusqu'au ski.The three components of the wall of the resulting shoe, that is to say the wall of the outer shell, the wall of the shoe, and the wall of the comfort shoe, are sized to bear against each other so to obtain a powerful shoe in the transmission of efforts from the foot to the ski.

Une telle solution de l'invention offre une grande flexibilité pour les magasins de location de matériel. D'abord, l'acquisition d'une série de chaussures est beaucoup moins chère. Ensuite, comme une même coque peut être utilisée pour plusieurs pointures différentes selon l'ajout d'un élément amovible, un sabot, il est beaucoup moins probable de tomber en panne de disponibilité d'une certaine pointure, puisqu'il suffit d'avoir une quantité suffisante de sabots en stock pour réduire ce risque.Such a solution of the invention offers great flexibility for hardware rental stores. First, the acquisition of a series of shoes is much cheaper. Then, as the same shell can be used for several different sizes depending on the addition of a removable element, a shoe, it is much less likely to run out of availability of a certain size, since it is sufficient to have a sufficient amount of hooves in stock to reduce this risk.
