Description

L'invention concerne un chausson intérieur pour chaussure de sport, particulièrement adapté pour les chaussures utilisées dans les sports de glisse tel que le ski. Elle concerne aussi une chaussure de sport comprenant un tel chausson.The invention relates to an inner boot for sports shoes, particularly suitable for shoes used in sports such as skiing. It also relates to a sports shoe comprising such a shoe.

Une chaussure de ski, surf des neiges, etc., se compose en général d'une tige rigide entourant un chausson dont une des fonctions est de garantir le confort du skieur malgré la pression élevée exercée par la tige rigide, qui remonte jusqu'à son tibia. Selon une solution courante de l'art antérieur, un tel chausson comprend une languette dans sa partie antérieure qui ferme par l'intérieur une échancrure, qui peut s'écarter sous la pression du pied à travers cette échancrure et une échancrure de la tige rigide de la chaussure pour faciliter le chaussage et le déchaussage de la chaussure. Pour cela, la languette est montée mobile en rotation sur l'avant du chausson pour pouvoir occuper une position avancée écartée du chausson. Toutefois, cette solution présente l'inconvénient que la languette se retrouve souvent mal positionnée par rapport au reste du chausson. Elle a notamment tendance à se coincer latéralement sur la surface extérieure du chausson. En effet, lors d'un chaussage par exemple, le pied de l'utilisateur exerce une pression sur la languette qui s'écarte vers l'avant, une partie au moins de cette languette se trouvant alors positionnée au-delà de l'échancrure du chausson. Dans cette position écartée de la languette, les bords semi-rigides de la languette croisent les bords souples de l'échancrure du chausson en général au niveau du cou de pied. En fin de chaussage, la languette a tendance à ne pas revenir facilement dans sa position de repos, au moins une partie de ses extrémités restant coincée sur la surface extérieure du chausson. Un tel problème a également été identifié dans le chausson selon le document EP-A-1 084 638 . Ce phénomène est particulièrement courant au niveau du cou de pied, où l'échancrure du chausson est très étroite et favorise le coincement de la languette. Or cette zone du cou de pied du chausson est recouverte par la tige rigide de la chaussure, est peu visible et peu accessible par l'utilisateur, qui, même s'il s'aperçoit de ce mauvais positionnement, éprouve de grandes difficultés pour remettre manuellement la languette en place. Finalement, le phénomène précédent a pour conséquences que cette solution courante de chausson de l'art antérieur se caractérise par un manque de confort et des douleurs ressenties par l'utilisateur, en plus d'un mauvais maintien du pied.A ski boot, snowboard, etc., generally consists of a rigid rod surrounding a liner, one of whose functions is to guarantee the skier's comfort despite the high pressure exerted by the rigid rod, which goes back to his shin. According to a common solution of the prior art, such a liner comprises a tongue in its front part which closes an indentation from the inside, which can deviate under the pressure of the foot through this notch and a notch of the rigid rod. the shoe to facilitate the boot and the heaving of the shoe. For this, the tongue is rotatably mounted on the front of the liner to be able to occupy an advanced position away from the liner. However, this solution has the disadvantage that the tongue is often poorly positioned relative to the rest of the shoe. In particular, it tends to become wedged laterally on the outer surface of the liner. Indeed, during a boot for example, the foot of the user exerts pressure on the tab which deviates forwards, at least a portion of this tongue being then positioned beyond the notch slipper. In this position away from the tongue, the semi-rigid edges of the tongue cross the soft edges of the notch of the boot generally at the instep. At the end of boot, the tongue tends not to return easily to its rest position, at least a portion of its ends remaining stuck on the outer surface of the boot. Such a problem has also been identified in the shoe according to the document EP-A-1 084 638 . This phenomenon is particularly common in the instep, where the notch of the liner is very narrow and promotes the jamming of the tongue. But this area of the instep of the bootie is covered by the rigid upper of the shoe, is not very visible and not easily accessible by the user, who, even if he realizes this bad positioning, has great difficulties to put back manually the tab in place. Finally, the foregoing phenomenon has the consequence that this current slipper solution of the prior art is characterized by a lack of comfort and pain felt by the user, in addition to poor foot maintenance.

Il existe donc un besoin d'une nouvelle structure de chausson de chaussure de sport qui permette d'éviter les inconvénients précédents.There is therefore a need for a new shoe boot structure that avoids the previous disadvantages.

Un objet de la présente invention consiste donc à proposer un chausson de chaussure de sport assurant un bon maintien du pied et au chaussage facile, tout en offrant un confort amélioré.An object of the present invention is therefore to provide a shoe shoe slipper ensuring good support and easy footwear, while providing improved comfort.

Selon le concept de l'invention, le chausson comprend une languette traditionnelle dans sa partie antérieure, recouverte par deux rabats superposés au niveau du cou de pied pour éviter toute dérive et coincement de la languette.According to the concept of the invention, the liner comprises a traditional tongue in its front part, covered by two overlapping flaps at the instep to prevent drifting and jamming of the tongue.

L'invention est plus précisément définie par les revendications.The invention is more precisely defined by the claims.

Ces objets, caractéristiques et avantages de la présente invention seront exposés en détail dans la description suivante d'un mode d'exécution particulier fait à titre non-limitatif en relation avec les figures jointes parmi lesquelles.

  • La figure 1 illustre une vue en perspective d'un chausson de chaussure de ski selon un mode d'exécution de l'invention ;
  • La figure 2 illustre une vue en perspective du chausson précédent dont les rabats et la languette sont représentés écartés de leur position de repos.
These objects, features and advantages of the present invention will be set forth in detail in the following description of a particular embodiment made in a non-limiting manner in relation to the attached figures among which.
  • The figure 1 illustrates a perspective view of a ski boot boot according to one embodiment of the invention;
  • The figure 2 illustrates a perspective view of the previous shoe whose flaps and tongue are shown spaced apart from their rest position.

Le chausson 1 pour chaussure de ski illustré sur les figures comprend une tige montée sur une semelle, adaptée pour remonter jusqu'au bas de jambe d'un skieur. La partie haute de la tige forme donc un collier 2 ouvert dans sa partie antérieure grâce à ses deux extrémités 3, 3' sensiblement verticales délimitant une échancrure antérieure occupée par une languette 4. Cette languette 4 s'étend sur une grande partie du chausson, de même que l'échancrure antérieure de la tige, et est reliée au chausson dans sa partie basse vers l'avant de la tige de manière mobile en rotation autour d'un axe 5 sensiblement horizontal et transversal à la chaussure. Elle est donc adaptée pour un mouvement vers l'avant selon la flèche F permettant d'agrandir l'ouverture supérieure 6 prévue pour insérer le pied du skieur. La figure 2 illustre plus précisément une telle position de la languette alors que la figure 1 illustre sa position de repos.The boot 1 for a ski boot illustrated in the figures comprises a rod mounted on a sole, adapted to go up to the bottom of a skier's leg. The upper part of the rod thus forms a collar 2 open in its front part thanks to its two substantially vertical ends 3, 3 'delimiting an anterior notch occupied by a tongue 4. This tongue 4 extends over a large part of the shoe, as the anterior notch of the rod, and is connected to the liner in its lower part towards the front of the rod rotatably about a substantially horizontal axis and transverse to the shoe. It is therefore adapted for a forward movement along the arrow F to enlarge the upper opening 6 provided to insert the foot of the skier. The figure 2 illustrates more precisely such a position of the tongue while the figure 1 illustrates its rest position.

Selon l'invention, le chausson présente deux rabats superposés 7, 7' semi-rigides, reliés respectivement aux deux extrémités latérales 13, 13' du chausson autour de son échancrure centrale antérieure au niveau du cou de pied du skieur, abusivement appelé cou de pied du chausson. Ces rabats présentent une extrémité libre et sont aptes à coulisser l'un sur l'autre. Ils peuvent ainsi s'écarter, comme cela est représenté sur la figure 2, sous l'effet de la pression de la languette 4. Ils ont une largeur sensiblement égale à celle de l'échancrure, ce qui garantit leur superposition dans toutes les configurations d'utilisation du chausson. Selon l'exemple illustré sur les figures, les rabats s'étendent sur environ toute la zone du cou de pied du skieur. Ils possèdent pour cela une forme tri-dimensionnelle adaptée, en forme de double tuile selon deux directions perpendiculaires, une première forme de tuile dans le sens du chausson, c'est à dire de bas en haut sur sa tige, dont le centre de courbure est positionné à l'extérieur du chausson, et une seconde tuile dans le sens transversal au chausson, parallèle à l'axe 5, dont le centre de courbure est positionné à l'intérieur du chausson. D'autres dimensions des rabats sont possibles sans sortir du cadre de l'invention. Par exemple, ils pourraient présenter une largeur légèrement inférieure, la largeur étant mesurée selon l'axe transversal au chausson, calculée pour que les rabats restent superposés, même dans une position écartée comme sur la figure 2. De même, ils pourraient présenter une hauteur différente, mesurée dans le sens du chausson. Par exemple, ils pourraient se présenter sous la forme de simples bandes, par exemple de hauteur de deux centimètres, et déjà permettre d'obtenir un effet technique positif. Inversement, ils pourraient remonter plus haut et couvrir aussi une partie inférieure du collier.According to the invention, the liner has two superimposed flaps 7, 7 'semi-rigid, respectively connected to the two lateral ends 13, 13' of the liner around its anterior central notch at the instep of the skier, wrongly called the neck of foot of the bootie. These flaps have a free end and are able to slide on one another. They can thus deviate, as shown on the figure 2 , under the effect of the pressure of the tongue 4. They have a width substantially equal to that of the notch, which ensures their superposition in all configurations of use of the shoe. According to the example illustrated in the figures, the flaps extend about the entire area of the skier's instep. For this purpose, they have a suitable three-dimensional shape, in the form of a double tile in two perpendicular directions, a first shape of tile in the direction of the slipper, ie from bottom to top on its stem, whose center of curvature is positioned outside the liner, and a second tile in the direction transverse to the liner, parallel to the axis 5, whose center of curvature is positioned inside the liner. Other dimensions of the flaps are possible without departing from the scope of the invention. For example, they could have a slightly smaller width, the width being measured along the axis transverse to the boot, calculated so that the flaps remain superimposed, even in a position apart as on the figure 2 . Similarly, they could have a different height, measured in the direction of the slipper. For example, they could be in the form of simple strips, for example two centimeters high, and already allow to obtain a positive technical effect. Conversely, they could go up higher and also cover a lower part of the necklace.

Plus en avant de la tige, l'échancrure du chausson est recouverte par une bande élastique 8 qui recouvre la languette 4 et au moins la partie inférieure des rabats 7, 7'.Further forward of the upper, the notch of the liner is covered by an elastic band 8 which covers the tongue 4 and at least the lower part of the flaps 7, 7 '.

La fonction des rabats va maintenant être expliquée. Dans une situation de chaussage du chausson, le pied du skieur va donc exercer un effort sur la languette 4 qui va s'écarter vers l'avant en provoquant l'écartement des rabats 7, 7', qui coulissent l'un par rapport à l'autre au niveau de leur zone de superposition. En fin de chaussage, les rabats et la languette vont reprendre leur position initiale de repos. Les rabats, qui sont au-dessus de la languette, vont assister son retour en position de repos à l'intérieur de l'échancrure du chausson. Ils vont remplir dans tous les cas une fonction de maintien de la languette, limitant son mouvement vers l'avant et exerçant un effort de rappel vers la position de repos prévu pour la pratique du ski. Le positionnement de ces rabats au niveau du cou de pied limite l'amplitude de la rotation vers l'avant de la languette et empêche une partie de la languette de passer à l'extérieur du chausson, notamment dans la zone du cou de pied, empêchant ainsi son mauvais positionnement sur la surface extérieure latérale du chausson au niveau du cou de pied en empêchant son coincement sur les bords 13, 13' de l'échancrure.The function of the flaps will now be explained. In a slipper boot situation, the foot of the skier will therefore exert a force on the tongue 4 which will move forward by causing the spacing of the flaps 7, 7 ', which slide with respect to the other at their superposition area. At the end of donnage, the flaps and the tongue will resume their initial position of rest. The flaps, which are above the tongue, will assist his return to the rest position inside the notch of the shoe. They will fill in any case a function of maintaining the tongue, limiting its forward movement and exerting a return force to the rest position provided for the practice of skiing. The positioning of these flaps at the level of the instep limits the amplitude of the rotation towards the front of the tongue and prevents part of the tongue from passing to the outside of the slipper, especially in the area of the instep, thus preventing its bad positioning on the outer lateral surface of the liner at the instep by preventing it from being wedged on the edges 13, 13 'of the notch.

La bande élastique 8 remplit une fonction similaire de maintien élastique mais reste optionnelle, les rabats pouvant suffire à une bonne performance.The elastic band 8 performs a similar function of elastic retention but remains optional, the flaps being sufficient for good performance.

Avantageusement, les rabats seront réalisés dans un matériau glissant, au moins au niveau de leur surface de contact, afin de favoriser leurs mouvements de coulissements, sous l'effort du pied d'un skieur, ce qui donne au chausson une bonne flexibilité et réactivité aux contraintes exercées par le skieur. De plus, un matériau semi-rigide sera de même avantageux pour atteindre un bon compromis entre la nécessité de maintien élastique de la languette et celle de souplesse pour permettre le mouvement vers l'avant selon la flèche F de la languette pour le chaussage du chausson. Pour cela, un matériau plastique convient particulièrement bien pour les rabats, qui pourront ainsi par exemple être en PVC ou en polyuréthane, de dureté inférieure ou égale à 40 shD. On pourra ainsi par exemple former des rabats en plastique selon une structure monolithique, par injection ou thermoformage, puis les rapporter sur le reste du chausson.Advantageously, the flaps will be made of a sliding material, at least at their contact surface, to promote their sliding movements, under the effort of the foot of a skier, which gives the shoe a good flexibility and responsiveness to the stresses exerted by the skier. In addition, a semi-rigid material will also be advantageous to achieve a good compromise between the need for elastic retention of the tongue and that of flexibility to allow forward movement along the arrow F of the tongue for the boot slipper . For this, a plastic material is particularly suitable for the flaps, which may for example be made of PVC or polyurethane, of hardness less than or equal to 40 shD. It will thus be possible, for example, to form plastic flaps in a monolithic structure, by injection or thermoforming, and then to report them to the rest of the liner.

Selon une variante de réalisation intéressante, la surface supérieure de la languette 4 est de même recouverte d'un matériau plastique au moins dans la zone où elle est recouverte par les rabats pour faciliter le glissement réciproque de la languette et des rabats.According to an interesting embodiment, the upper surface of the tongue 4 is likewise covered with a plastic material at least in the area where it is covered by the flaps to facilitate the reciprocal sliding of the tongue and the flaps.

Le reste du chausson pourra être réalisé selon les procédés habituels, à base de matériaux plus souples comme des tissus et des mousses. La liaison entre les rabats et la tige du chausson peut être positionnée différemment et se faire par toute technique connue, couture, soudure ultrason...Selon un procédé de fabrication possible, les rabats pourraient être formés par une surinjection d'un matériau plastique sur le reste du chausson. Selon une autre variante, au moins une partie de la surface extérieure du collier pourrait aussi être recouverte par le même matériau plastique que les rabats lors de la même étape d'injection, les rabats venant alors dans la continuité du collier et formant une seule pièce avec sa couche de surface semi-rigide.The rest of the liner can be made according to the usual methods, based on softer materials such as fabrics and foams. The connection between the flaps and the liner shaft can be positioned differently and be done by any known technique, sewing, ultrasonic welding ... According to a possible manufacturing process, the flaps could be formed by a super-injection of a plastic material on the rest of the shoe. According to another variant, at least a portion of the outer surface of the collar could also be covered by the same plastic material as the flaps during the same injection step, the flaps then coming in the continuity of the collar and forming a single piece with its semi-rigid surface layer.

L'invention a été illustrée dans le cadre d'un chausson pour chaussure de ski, mais pourrait être implémentée sur tout chausson de sport montant, comprenant un collier remontant sur le bas de jambe, distinct ou non d'une tige de chaussure, fortement pressé contre le pied ou la jambe.The invention has been illustrated in the context of a boot for a ski boot, but could be implemented on any sporting boot, including a collar going up on the lower leg, distinct or not a shoe upper, strongly pressed against the foot or leg.

Finalement, la solution atteint bien les objets recherchés et présente les avantages suivants :

  • le chaussage/déchaussage du chausson reste facile, la languette étant toujours dotée de son mouvement de rotation vers l'avant pour s'écarter sous l'effet de la pression d'un pied lors du chaussage et du déchaussage;
  • le maintien du pied est garanti. La languette, qui reste en position de repos dans l'échancrure du chausson, assure un bon maintien notamment sur le pourtour du bas de jambe de l'utilisateur. D'autre part, l'effort de maintien exercé par les rabats sur la languette au niveau du cou de pied représente une force qui tend à maintenir le talon de l'utilisateur en position dans le chausson. Cette solution procure une sensation de meilleur enveloppement du pied et permet d'atteindre une meilleure efficacité de la chaussure ;
  • enfin, la solution retenue améliore le confort de l'utilisateur en garantissant le bon positionnement de la languette.
Finally, the solution achieves the desired objects and has the following advantages:
  • the boot / heaving of the liner remains easy, the tongue is always provided with its forward rotation to move away under the effect of the pressure of a foot during the boot and heaving;
  • foot support is guaranteed. The tongue, which remains in the rest position in the notch of the shoe, ensures a good support especially on the periphery of the lower leg of the user. On the other hand, the holding force exerted by the flaps on the tongue at the instep is a force that tends to maintain the heel of the user in position in the boot. This solution provides a feeling of better wrapping of the foot and allows to achieve a better efficiency of the shoe;
  • finally, the chosen solution improves the comfort of the user by ensuring the correct positioning of the tongue.
