Description

La présente invention concerne particulièrement les chaussures de ski et plus généralement les chaussures de sport qui nécessitent un maintien ferme du pied pour la pratique sportive à laquelle elles sont dédiées. C'est donc notamment le cas dans le domaine du ski, qu'il s'agisse du ski alpin sur piste, du ski de randonnée et dans une moindre mesure du ski de fond.The present invention particularly relates to ski boots and more generally to sports shoes which require firm support of the foot for the sporting practice to which they are dedicated. This is particularly the case in the field of skiing, whether on-piste alpine skiing, ski touring and to a lesser extent cross-country skiing.

Pour pratiquer le ski alpin, l'utilisateur doit exercer sur ses skis des efforts relativement importants pour piloter ces derniers et choisir sa trajectoire. Ces efforts, même s'ils sont générés au niveau du corps tout entier, passent nécessairement, en dernier ressort, par le pied. Afin de faciliter la transmission d'effort, il est habituel de doter les chaussures de ski d'une coque extérieure qui aide le skieur. En ski alpin, cette coque extérieure qui est relativement rigide peut être source d'inconfort et de douleur même si un chausson intérieur de confort est placé entre le pied de l'utilisateur et la coque. C'est le cas notamment lorsque le pied de l'utilisateur présente une morphologie bien différente de celle qui a servi de modèle pour la conception de la chaussure.To practice alpine skiing, the user must exert relatively significant effort on their skis to control them and choose their trajectory. These efforts, even if they are generated at the level of the entire body, necessarily pass, ultimately, through the foot. In order to facilitate the transmission of effort, it is customary to equip ski boots with an outer shell which helps the skier. In alpine skiing, this outer shell which is relatively rigid can be a source of discomfort and pain even if a comfort inner liner is placed between the user's foot and the shell. This is particularly the case when the user's foot has a morphology that is very different from that which served as a model for the design of the shoe.

Parmi les différentes zones du pied, l'une est particulièrement affectée par le dilemme confort/maintien, c'est le dessus du pied, et notamment le dessus du cou-de-pied. En effet, c'est sur cette zone que viennent presser les crochets de fermetures.Among the different areas of the foot, one is particularly affected by the comfort/support dilemma, it is the top of the foot, and in particular the top of the instep. In fact, it is on this area that the closing hooks press.

Les constructeurs, les revendeurs, les spécialistes du bootfitting ainsi que les utilisateurs eux-mêmes ont bien sûr tenté de mettre en oeuvre diverses techniques de modification des chaussures pour les adapter aux différentes morphologies, mais aucune de ces tentatives n'est entièrement satisfaisante. Il est par exemple connu d'utiliser des mousses thermoformables pour confectionner le chausson interne. Ces mousses ont la particularité de pouvoir se déformer durablement après avoir été chauffées. Même si l'utilisation de ces mousses a apporté une réelle amélioration pour le confort des utilisateurs, elles ne peuvent pas répondre convenablement à toutes les situations. Notamment, elles ne peuvent être placées avantageusement que dans des zones où l'épaisseur de mousse est importante. C'est pourquoi, en général, les pads de mousse thermoformables sont souvent utilisés sur les côtés du chausson. De plus, il nécessaire d'utiliser un dispositif chauffant afin d'amener le chausson à la température permettant le thermoformage.Manufacturers, retailers, bootfitting specialists as well as users themselves have of course attempted to implement various techniques for modifying shoes to adapt them to different body types, but none of these attempts is entirely satisfactory. For example, it is known to use thermoformable foams to make the inner liner. These foams have the particularity of being able to deform permanently after being heated. Even if the use of these foams has brought a real improvement in user comfort, they cannot respond adequately to all situations. In particular, they can only be advantageously placed in areas where the thickness of the foam is significant. This is why, in general, thermoformable foam pads are often used on the sides of the liner. In addition, it is necessary to use a heating device to bring the liner to the temperature allowing thermoforming.

Il est également connu de fabriquer la coque dans des matériaux qui sont thermoformables et qui le sont à des températures suffisamment basses pour ne pas risquer de blesser les utilisateurs. En effet, la finalité étant d'adapter la chaussure au pied de l'utilisateur, il y a toujours un moment où la chaussure chauffée sera en contact avec le pied. Le thermoformage de la coque est également un progrès pour garantir une parfaite adéquation entre le volume intérieur de celle-ci et le pied de l'utilisateur. Néanmoins, il s'agit d'un procédé qui nécessite l'utilisation précautionneuse d'un four chauffant et qu'il est préférable de réserver aux professionnels. EP 3 581 053 A1 divulgue une chaussure de ski selon le préambule de la revendication 1.It is also known to manufacture the shell in materials which are thermoformable and which are so at temperatures low enough so as not to risk injuring the users. Indeed, the aim being to adapt the shoe to the user's foot, there is always a moment when the heated shoe will be in contact with the foot. The thermoforming of the shell is also progress to guarantee a perfect match between the interior volume of the shell and the user's foot. However, this is a process that requires the careful use of a heating oven and is best reserved for professionals. EP 3 581 053 A1 discloses a ski boot according to the preamble of claim 1.

L'objectif de l'invention est de compléter les techniques connus d'adaptation du confort d'une chaussure de ski avec des moyens simples, accessibles et qui concernent le dessus du pied.The objective of the invention is to complete the known techniques for adapting the comfort of a ski boot with simple, accessible means which concern the top of the foot.

L'objectif de l'invention est atteint par la fourniture d'une chaussure de ski comportant une coque extérieure et un chausson interne de confort, ledit chausson ayant une ouverture frontale et une languette mobile qui est fixée au niveau de son extrémité basse à la zone avant-pied du chausson grâce à des moyens d'attache amovibles et qui assure la fermeture de ladite ouverture frontale ; la languette étant constituée d'une portion rigide, qui est solidaire desdits moyens d'attache amovibles et d'une portion souple, lesdites portions rigides et souples étant indépendantes l'une de l'autre ; la portion souple de ladite languette comportant une face arrière destinée à venir au contact du pied d'un utilisateur et une face avant ; ladite face avant comprenant une première ouverture permettant mettre et de retirer la dite portion rigide dans un logement intérieur ménagé entre ladite face arrière et ladite face avant, ainsi qu'une deuxième ouverture au travers de laquelle lesdits moyens d'attache amovible peuvent passer lorsque la portion rigide est en place dans le logement intérieur.The objective of the invention is achieved by providing a ski boot comprising an outer shell and an internal comfort liner, said liner having a front opening and a movable tongue which is fixed at its lower end to the forefoot area of the liner thanks to removable attachment means and which ensures the closure of said front opening; the tongue being made up of a rigid portion, which is integral with said removable attachment means and a flexible portion, said rigid and flexible portions being independent of each other; the flexible portion of said tongue comprising a rear face intended to come into contact with the foot of a user and a front face; said front face comprising a first opening allowing said rigid portion to be placed and removed in an interior housing provided between said rear face and said front face, as well as a second opening through which said removable attachment means can pass when the rigid portion is in place in the interior housing.

De préférence, la portion rigide comporte des moyens de traction permettant de tirer vers le haut la languette, lesdits moyens de traction étant prévus pour traverser la dite première ouverture lorsque la portion rigide de la languette est en place dans le logement intérieur.Preferably, the rigid portion comprises traction means making it possible to pull the tongue upwards, said traction means being provided to pass through said first opening when the rigid portion of the tongue is in place in the interior housing.

Dans un mode de réalisation préféré, la face avant de la portion souple comprend un panneau supérieur et un panneau inférieur, la deuxième ouverture étant à la jonction entre le panneau inférieur et la face arrière de la portion souple.In a preferred embodiment, the front face of the flexible portion comprises an upper panel and a lower panel, the second opening being at the junction between the lower panel and the rear face of the flexible portion.

Pour améliorer le confort de l'utilisateur, des pads amortissants amovibles peuvent être collés en différents endroits judicieusement choisis sur la face arrière de la portion rigide.To improve user comfort, removable shock-absorbing pads can be glued in various carefully chosen locations on the rear side of the rigid portion.

La figure 1 montre une chaussure de ski 1 selon l'invention. Elle comprend une coque extérieure 2, un chausson intérieur 3 et plusieurs crochets 11 qui assurent la fermeture de la chaussure.There figure 1 shows a ski boot 1 according to the invention. It includes an outer shell 2, an inner liner 3 and several hooks 11 which ensure the closure of the shoe.

La coque peut être constituée de plusieurs pièces. Dans le cas précis, elle comprend un bas de coque et un collier qui sont deux éléments distincts mais rendus solidaires par des moyens de fixation. Cette coque 2 est généralement réalisée par injection de matières plastiques bien que d'autres procédés de fabrication soient envisageables comme par exemple la mise en forme de matériaux composites tels qu'un assemblage de tissus carbone et résine. La coque doit être relativement rigide afin d'assurer un bon maintien du pied du skieur et une bonne transmission d'effort pour permettre le pilotage du ski. Cette rigidité est source d'inconfort sur le dessus du pied, notamment lorsque les crochets sont bien serrés.The hull can be made up of several parts. In the specific case, it comprises a bottom of the shell and a collar which are two distinct elements but held together by fixing means. This shell 2 is generally made by injection of plastic materials although other manufacturing processes are possible such as for example the shaping of composite materials such as an assembly of carbon and resin fabrics. The shell must be relatively rigid in order to ensure good support for the skier's foot and good transmission of force to allow the ski to be controlled. This rigidity is a source of discomfort on the top of the foot, especially when the hooks are tight.

Le confort du pied repose en grande partie sur le chausson interne 3, lequel est représenté en perspective avant à la figure 2. Il s'agit d'un élément chaussant confectionné de nombreuses pièces distinctes qui ne seront pas toutes décrites en détail ici. Pour faciliter l'insertion du pied, le chausson présente une grande ouverture 31 sur le dessus de celui-ci. Cette ouverture 31 est refermée par une languette 5 fixée sur l'avant du chausson 32. Les moyens de fixation de la languette 5 sur le chausson peuvent être de toutes sortes à condition qu'ils soient amovibles. En effet, une des caractéristiques de la chaussure de ski de l'invention est que l'utilisateur ait la possibilité de retirer facilement la languette afin de la modifier dans le but de l'adapter à sa morphologie. Dans le cas d'espèce, les moyens de fixation de la languette sont constitués, d'une part d'une première bande auto-agrippante 34 placée sur l'avant du chausson et d'une deuxième bande auto-agrippante 511 complémentaire placée, comme on le verra plus loin à l'extrémité basse de la languette 5.The comfort of the foot relies largely on the internal liner 3, which is shown in front perspective at the figure 2 . This is a footwear item made of many distinct pieces which will not all be described in detail here. To facilitate insertion of the foot, the liner has a large opening 31 on the top of it. This opening 31 is closed by a tongue 5 fixed on the front of the liner 32. The means of fixing the tongue 5 on the liner can be of all kinds as long as they are removable. Indeed, one of the characteristics of the ski boot of the invention is that the user has the possibility of easily removing the tongue in order to modify it in order to adapt it to his morphology. In the present case, the means for fixing the tongue consist of, on the one hand, a first hook-and-loop strip 34 placed on the front of the liner and a second complementary hook-and-loop strip 511 placed, as will be seen later at the lower end of tab 5.

Une bride 33 est placée à la base de l'ouverture 31 pour s'assurer qu'au cours du chaussage ou du déchaussage, la languette 5 ne quitte pas sa position à l'intérieur du chausson. Cette bride 33 consiste en un pont 331 inextensible et en une bande élastique 332.A flange 33 is placed at the base of the opening 31 to ensure that during putting on or taking off, the tongue 5 does not leave its position inside the liner. This flange 33 consists of an inextensible bridge 331 and an elastic band 332.

La languette 5 peut être aisément désolidarisée du reste du chausson en déconnectant les première et deuxième bande auto-agrippante l'une de l'autre. La figure 3 montre la languette 5 en perspective. Celle-ci est constituée d'une portion souple 52 et d'une portion rigide 51. lesdites portions rigides et souples sont indépendantes l'une de l'autre, c'est-à-dire qu'elles peuvent aisément être séparées l'une de l'autre. La portion rigide 51 est représentée seule à la figure 5. Elle est constituée principalement par une plaque solide 512 obtenue par injection de matière plastique, par exemple en polyamide ou en polyurethane.The tongue 5 can be easily separated from the rest of the liner by disconnecting the first and second hook-and-loop strips from each other. There Figure 3 shows tab 5 in perspective. This consists of a flexible portion 52 and a rigid portion 51. said rigid and flexible portions are independent of each other, that is to say they can easily be separated one from the other. The rigid portion 51 is shown alone in the figure 5 . It is mainly made up of a solid plate 512 obtained by injection of plastic material, for example polyamide or polyurethane.

La portion rigide 51 donne à la languette sa structure et son maintien et assure d'autre part la fixation de la languette 5 au reste du chausson. En effet, les moyens de fixation de la languette sur l'avant du chausson sont constitués par la deuxième bande auto-agrippante 511 qui prolonge vers l'avant la portion rigide 51. La bande auto-agrippante 511 pourra être elle-même fixée par couture à la plaque de la portion rigide.The rigid portion 51 gives the tongue its structure and its support and also ensures the fixing of the tongue 5 to the rest of the liner. Indeed, the means for fixing the tongue on the front of the liner are constituted by the second hook-and-loop strip 511 which extends the rigid portion 51 forward. The hook-and-loop strip 511 can itself be fixed by seam to the plate of the rigid portion.

La portion souple 52, qui est montrée à la figure 6, désolidarisée de la portion rigide 51, se présente sous la forme d'un assemblage de plusieurs éléments souple de type textile, panneaux de mousse ou encore films plastique, lesquels sont fixés les uns aux autres par collage, couture ou autre méthode équivalente. Elle présente une face arrière 521 et une face avant 522. La fonction principale de la face arrière est d'améliorer le confort, notamment en évitant que la plaque solide de la portion rigide ne génère des points de pression douloureux sur le pied de l'utilisateur. La face avant 522, constituée d'un panneau supérieur 5221 et d'un panneau inférieur 5222, a pour fonction d'assurer la solidarisation de la portion rigide 51 et de la portion souple 52 de la languette 5. Pour ce faire, la face avant 522 présente une première ouverture 523 qui est localisée entre les panneaux supérieur et inférieur et qui permet la mise en place de la portion rigide 51 à l'intérieur de la portion souple 52, entre la face avant 522 et la face arrière 521 de celle-ci. Ainsi, la portion souple 52 présente un logement intérieur 525 ménagé entre la face avant 522 et la face arrière 521 dont l'accès est assuré par la première ouverture 523.The flexible portion 52, which is shown in Figure 6 , separated from the rigid portion 51, is in the form of an assembly of several flexible elements of textile type, foam panels or even plastic films, which are fixed to each other by gluing, sewing or other equivalent method. It has a rear face 521 and a front face 522. The main function of the rear face is to improve comfort, in particular by preventing the solid plate of the rigid portion from generating painful pressure points on the foot of the user. The front face 522, consisting of an upper panel 5221 and a lower panel 5222, has the function of ensuring the joining of the rigid portion 51 and the flexible portion 52 of the tongue 5. To do this, the face front 522 has a first opening 523 which is located between the upper and lower panels and which allows the installation of the rigid portion 51 inside the flexible portion 52, between the front face 522 and the rear face 521 of that -this. Thus, the flexible portion 52 has an interior housing 525 provided between the front face 522 and the rear face 521, access to which is provided by the first opening 523.

La portion souple 52 se caractérise également par la présence d'une deuxième ouverture 524, placée à l'extrémité basse de la languette, à l'interface entre face avant 522 et face arrière 521. Comme on peut le voir à la figure 4, cette ouverture sert au passage de la deuxième bande auto-agrippante 511. La face arrière 521 se caractérise par une épaisseur plus importante que la face avant afin de garantir un meilleur confort pour l'utilisateur. Cette épaisseur est obtenue par la mise en place d'un ou de plusieurs panneaux de mousse.The flexible portion 52 is also characterized by the presence of a second opening 524, placed at the lower end of the tongue, at the interface between front face 522 and rear face 521. As can be seen in the figure 4 , this opening is used for the passage of the second hook-and-loop strip 511. The rear face 521 is characterized by a greater thickness than the front face in order to guarantee better comfort for the user. This thickness is obtained by installing one or more foam panels.

La portion rigide 51 est, comme cela est dit plus haut, constituée d'une plaque solide obtenue par injection de matière plastique, à laquelle sont fixés, notamment des moyens d'attaches 511 et des moyens de traction 515. Ces moyens peuvent être fixés par couture à la plaque solide. Les moyens de traction 515 sont constitués par une bande fixée à la plaque solide dans une zone de cette dernière qui ne trouve pas recouverte par le panneau supérieur 5221 de la face avant 522 lorsque la portion rigide 51 de la languette est en place, à l'intérieur de la portion souple 52. Lorsque l'utilisateur exerce une traction sur les moyens de traction 515, il y a transmission de l'effort de traction jusque l'avant du chausson par l'intermédiaire de la deuxième bande auto-agrippante 511. Ceci a, bien entendu, pour effet de repositionner correctement la languette, laquelle peut avoir tendance à glisser vers l'intérieur du chausson lorsque l'utilisateur y glisse son pied. Cependant, grâce à la configuration judicieuse de la languette selon l'invention, l'action sur les moyens de traction et le repositionnement de la languette n'ont aucun effet sur la liaison entre portion rigide 51 et portion souple 52 de la languette 5.The rigid portion 51 is, as said above, made up of a solid plate obtained by injection of plastic material, to which are fixed, in particular fastening means 511 and traction means 515. These means can be fixed by sewing to the solid plate. The traction means 515 consist of a strip fixed to the solid plate in an area of the latter which is not covered by the upper panel 5221 of the front face 522 when the portion rigid 51 of the tongue is in place, inside the flexible portion 52. When the user exerts traction on the traction means 515, there is transmission of the traction force to the front of the liner by via the second hook-and-loop strip 511. This has, of course, the effect of correctly repositioning the tongue, which may tend to slide towards the inside of the liner when the user slides their foot into it. However, thanks to the judicious configuration of the tongue according to the invention, the action on the traction means and the repositioning of the tongue have no effect on the connection between rigid portion 51 and flexible portion 52 of tongue 5.

Etant donné que la plaque rigide est réalisée par injection plastique, il est possible de lui donner une forme bien spécifique et notamment de prévoir des nervures de rigidification 514 ainsi qu'un plateau surélevé 513.Given that the rigid plate is made by plastic injection, it is possible to give it a very specific shape and in particular to provide stiffening ribs 514 as well as a raised plate 513.

Le fonctionnement, et les avantages que la languette selon l'invention procure, vont maintenant être décrits en détail. Au moment de l'achat, lors du premier essayage de la chaussure par l'utilisateur, si une sensation d'inconfort ou de douleur est perçue, on essaye, au mieux, de localiser la zone générant la douleur. Cela peut être, par exemple, un point de pression qui s'exerce au niveau du cou de pied. Dans ce cas, il est possible que ce soit la languette qui en soit la cause. Le professionnel qui conseille l'utilisateur lors de l'achat, ou l'utilisateur, lui-même, retire alors le chausson interne de la coque, puis désolidarise la languette 5 du reste du chausson 3, en défaisant les moyens d'attache (ici les bandes auto-agrippantes). Ensuite, la portion rigide de la languette 51 est retirée de son emprisonnement à l'intérieur de la portion souple 52. Cette action est facilitée par le fait que le panneau supérieur 5221 et le panneau inférieur 5222 de la face avant de la portion souple sont non seulement souples, mais également légèrement extensibles. Plusieurs actions d'adaptation ou d'échange sont alors envisageables avec la portion rigide 51. Cette dernière peut être modifiée par déformation, par enlèvement de matière ou par découpage. On pourra réaliser une ou plusieurs découpes dans la portion rigide 51 aux endroits d'inconfort. Par exemple, il peut être relativement facile découper la zone du plateau surélevé 513. En effet, celui-ci se trouve exactement au niveau du dessus du cou de pied, une zone particulièrement sujette aux sensations d'inconfort. On peut également y rajouter des pads amortissants 516 pour améliorer le confort.The operation, and the advantages that the tongue according to the invention provides, will now be described in detail. At the time of purchase, when the user first tries on the shoe, if a sensation of discomfort or pain is perceived, we try, as best we can, to locate the area generating the pain. This could be, for example, a pressure point on the instep. In this case, it is possible that the tab is the cause. The professional who advises the user during the purchase, or the user himself, then removes the internal liner from the shell, then separates the tab 5 from the rest of the liner 3, by undoing the attachment means ( here the hook-and-loop strips). Then, the rigid portion of the tongue 51 is removed from its imprisonment inside the flexible portion 52. This action is facilitated by the fact that the upper panel 5221 and the lower panel 5222 of the front face of the flexible portion are not only soft, but also slightly stretchy. Several adaptation or exchange actions are then possible with the rigid portion 51. The latter can be modified by deformation, by removal of material or by cutting. One or more cuts can be made in the rigid portion 51 at places of discomfort. For example, it can be relatively easy to cut out the area of the raised platform 513. Indeed, this is located exactly at the top of the instep, an area particularly prone to feelings of discomfort. You can also add 516 shock-absorbing pads to improve comfort.

La figure 7 représente une vue arrière d'une version alternative de la portion rigide de la languette. Trois pads amortissants 516 sont collés sur la face arrière de la portion rigide, c'est-à-dire sur la face qui est dirigée vers le pied de l'utilisateur. Ces pads amortissants sont amovibles et peuvent être décollés et replacés aux endroits désirés pour garantir le meilleur confort à l'utilisateur.There Figure 7 shows a rear view of an alternative version of the rigid portion of the tongue. Three shock-absorbing pads 516 are glued to the rear face of the rigid portion, that is to say on the face which is directed towards the user's foot. These cushioning pads are removable and can be taken off and replaced in the desired locations to guarantee the best comfort for the user.
