Abstract

The sports boot (10), comprising a sole (12), an upper (14) with fastenings and a covering flap (26), has the flap forming part of the upper and joined to it by an in-turned seam (18) on the side of the boot that is more subject to abrasion. One of the two pieces joined by the seam can be more rigid than the other to act as a reinforcing element, or both pieces can be flexible and waterproof.

Description

L'invention se rapporte au domaine des chaussures de ski de fond.The invention relates to the field of cross-country ski boots.

Les chaussures de ski de fond comportent une semelle qui peut être souple ou rigide et sur laquelle est montée une tige qui recouvre le pied de l'utilisateur. Cette tige est la plupart du temps réalisée sous la forme de plusieurs pièces qui sont découpées et assemblées entre elles de manière à former une enveloppe tridimensionnelle la plus proche possible de la forme du pied. Généralement, la forme de ces pièces et les matériaux qui les constituent sont dictés par la position desdites pièces et par la fonction que l'on veut leur faire remplir. Ainsi, la pièce peut être un renfort d'extrémité avant, auquel cas le matériau sera un matériau résistant, ou encore être une pièce de ventilation, auquel cas le matériau sera un matériau ajouré.Cross-country ski boots have a sole that can be flexible or rigid and on which is mounted a rod that covers the foot of the user. This rod is mostly made in the form of several pieces that are cut and assembled together to form a three-dimensional envelope as close as possible to the shape of the foot. Generally, the shape of these parts and the materials that constitute them are dictated by the position of said parts and the function that we want them to fill. Thus, the piece may be a front end reinforcement, in which case the material will be a resistant material, or be a ventilation piece, in which case the material will be a perforated material.

Dans la plupart des chaussures de ski de fond, la tige comporte des quartiers latéraux internes et externes qui sont destinés à être rapprochés l'un de l'autre par un système de serrage, le plus souvent un laçage. Ces quartiers sont alors séparés par une fente longitudinale en dessous de laquelle peut s'étendre une languette de confort.In most cross-country ski boots, the upper has internal and external lateral quarters which are intended to be brought closer to each other by a tightening system, most often a lacing. These neighborhoods are then separated by a longitudinal slot below which can extend a tab of comfort.

Dans certaines chaussures de ski de fond, la tige comporte un rabat de protection qui vient recouvrir le système de laçage, mais qui peut s'écarter pour permettre le laçage et le délaçage, donc le chaussage et le déchaussage de la chaussure. Ce rabat de protection est particulièrement utile pour les chaussures destinées à être portées dans la neige car il évite que la neige puisse s'introduire dans la chaussure au niveau de la fente qui sépare les quartiers latéraux de la tige.In some cross-country ski boots, the upper has a protective flap which covers the lacing system, but which can move apart to allow the lacing and delaçage, thus the boot and the heaving of the boot. This protective flap is particularly useful for shoes intended to be worn in the snow because it prevents the snow can be introduced into the shoe at the slot that separates the lateral areas of the rod.

Dans une conception classique de la tige, les différentes pièces qui la constituent sont en principe assemblées par couture (que l'on appelle aussi piquage). Pour cela, les pièces à assembler présentent des portions chevauchantes dans lesquelles deux pièces adjacentes sont superposées. Une couture traversante, visibles des deux côtés de la superposition, lie les deux pièces l'une à l'autre. Avec une couture traversante, le fil de couture est exposé sur les deux faces, donc notamment sur la face externe de la tige. Il se trouve ainsi exposé aux agressions extérieures et notamment aux frottements qui peuvent user le fil et donc provoquer la rupture de la couture. De même, il est connu que les coutures traversantes sont des points d'entrée de l'humidité dans la chaussure.In a conventional design of the stem, the various parts that constitute it are in principle assembled by stitching (also called stitching). For this, the parts to be assembled have overlapping portions in which two adjacent parts are superimposed. A through seam, visible on both sides of the overlay, binds the two pieces to each other. With a through seam, the sewing thread is exposed on both sides, especially on the outer face of the shank. It is thus exposed to external aggressions and especially to friction that can wear the thread and thus cause breakage of the seam. Similarly, it is known that the through seams are points of entry of moisture into the shoe.

L'invention a donc pour but de proposer une nouvelle conception de l'assemblage de certaines pièces de la tige d'une chaussure dans le but notamment d'en augmenter la résistance à l'usure et à la pénétration de l'humidité.The invention therefore aims to propose a new design of the assembly of certain parts of the upper of a shoe in order, in particular, to increase the resistance to wear and penetration of moisture.

Dans ce but, l'invention propose une chaussure telle que définie à la revendication 1.For this purpose, the invention provides a shoe as defined in claim 1.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui suit, ainsi qu'au vu des dessins annexés dans lesquels :

  • la figure 1 est une vue schématique en perspective avec arrachement d'une chaussure de ski de fond conforme aux enseignements de l'invention ;
  • la figure 2 est une vue agrandie de l'arrachement de la figure 1 illustrant plus en détail la couture jointée retournée ;
  • la figure 3 est une vue similaire à celle de la figure 1 dans laquelle le rabat de protection est ouvert ;
  • les figures 4 et 5 sont des vues similaires à celles des figures 1 et 2 mais illustrent un autre mode de réalisation d'une couture jointée retournée.
Other features and advantages of the invention will appear on reading the detailed description which follows, as well as in view of the appended drawings in which:
  • Figure 1 is a schematic perspective view with cutaway of a cross-country ski boot according to the teachings of the invention;
  • Fig. 2 is an enlarged view of the tear-away of Fig. 1 illustrating in more detail the reverse joined seam;
  • Figure 3 is a view similar to that of Figure 1 in which the protective flap is open;
  • Figures 4 and 5 are views similar to those of Figures 1 and 2 but illustrate another embodiment of an inverted joint seam.

Sur la figure 1, on a illustré une chaussure de ski de fond 10 qui comporte pour l'essentiel une semelle 12 sur laquelle une tige 14 est montée par toute technique connue. La tige 14 peut ainsi être montée par collage ou par piquage, ou toute autre méthode.In Figure 1, there is illustrated a cross-country ski boot 10 which comprises essentially a sole 12 on which a rod 14 is mounted by any known technique. The rod 14 can thus be mounted by gluing or stitching, or any other method.

La tige 14 de la chaussure selon l'invention est essentiellement une tige souple, c'est-à-dire une tige formée de matériaux tels que des tissus, du cuir ou des films de matière synthétique. Elle peut toutefois comporter des éléments plus rigides pour assurer un bon maintien du pied, tels que des contreforts rigides ou semi-rigides, ou tels qu'un collier de tenue de bas de jambe. De même, l'utilisation de matériaux qui sont par essence souples n'empêche pas de les utiliser dans des épaisseurs telles qu'ils possèdent une certaine rigidité.The upper 14 of the boot according to the invention is essentially a flexible rod, that is to say a rod formed of materials such as fabrics, leather or plastic films. However, it may comprise more rigid elements to ensure a good support of the foot, such as stiff or semi-rigid buttresses, or such as a lower leg collar. Similarly, the use of materials that are inherently flexible does not prevent them from being used in such thicknesses that they have a certain rigidity.

Dans l'exemple illustré, la chaussure est une chaussure de ski de fond dont la semelle 12 comporte des moyens d'accrochage 16 destinés à coopérer avec une fixation de ski de fond.In the example shown, the shoe is a cross-country ski boot whose sole 12 comprises attachment means 16 intended to cooperate with a cross-country ski binding.

La tige 14 est formée de plusieurs pièces, c'est-à-dire d'au moins deux pièces. Au moins deux de ces pièces sont assemblées par une couture jointée retournée 18.The rod 14 is formed of several pieces, that is to say at least two pieces. At least two of these pieces are assembled by an inverted joint seam 18.

Comme on peut le voir à la figure 3, la tige de la chaussure illustrée comporte des moyens de serrage, en l'occurrence un laçage 20, destinés à rapprocher deux quartiers 22 de la tige séparés par une fente longitudinale 24 qui s'étend dans la zone de cou de pied. La tige 14 comporte un rabat de protection 26 qui, dans une position ouverte illustrée à la figure 3, donne accès au laçage, et dans une position fermée illustrée à la figure 1, recouvre les moyens de serrage 20 et la fente longitudinale 24.As can be seen in FIG. 3, the upper of the shoe illustrated comprises clamping means, in this case a lacing 20, intended to bring two quarters 22 of the rod separated by a longitudinal slot 24 which extends into the area of the instep. The rod 14 comprises a protective flap 26 which, in an open position illustrated in FIG. 3, gives access to the lacing, and in a closed position illustrated in FIG. 1, covers the clamping means 20 and the longitudinal slot 24.

Ce rabat de protection 26 est constitué d'une pièce de matériau souple qui recouvre la portion de la tige 14 correspondant à la partie supérieure du pied allant de l'arrière des orteils jusqu'à la cheville. Le rabat 26 comporte donc deux bords longitudinaux interne et externe, et un bord avant 32 qui sont assemblés à d'autres pièces de la tige 14 par la couture jointée retournée 18. Les bords longitudinaux du rabat s'étendent le long des côtés du cou de pied de la chaussure, et le bord avant s'étend sensiblement transversalement au travers d'une zone correspondant à la zone de flexion métatarso-phalangienne de la chaussure. Le bord arrière du rabat 26 est libre, et le rabat 26 comporte une fermeture à glissière 28 qui débouche dans le bord arrière et qui délimite dans le rabat deux volets susceptibles de s'écarter l'un de l'autre lorsque la glissière 28 est ouverte pour donner accès au laçage. Le rabat 26 est de préférence réalisé en un matériau sensiblement imperméable, par exemple un tissu enduit ou une feuille de PVC.This protective flap 26 consists of a piece of flexible material which covers the portion of the rod 14 corresponding to the upper part of the foot from the back of the toes to the ankle. The flap 26 thus has two inner and outer longitudinal edges, and a front edge 32 which are joined to other parts of the rod 14 by the reverse jointed seam 18. The longitudinal edges of the flap extend along the sides of the neck foot of the shoe, and the front edge extends substantially transversely through an area corresponding to the metatarsophalangeal flexion zone of the shoe. The rear edge of the flap 26 is free, and the flap 26 has a zipper 28 which opens into the rear edge and which defines in the flap two flaps that can move away from one another when the slide 28 is open to give access to the lacing. The flap 26 is preferably made of a substantially impervious material, for example a coated fabric or a PVC sheet.

Par couture jointée retournée, on entend une couture 18 telle qu'illustrée à la figure 2 ou à la figure 5. A la figure 2, on voit que les deux pièces à assembler sont cousues l'une à l'autre au niveau de replis tournés vers l'intérieur. Une manière de réaliser une telle couture est de placer les deux pièces à assembler l'une contre l'autre, les faces externes en regard l'une de l'autre, et de préférence bord à bord. On effectue alors une couture, de préférence le long du bord des deux pièces, cette couture étant par exemple une couture traversante classique. On déplie alors les deux pièces pour les amener l'une dans le prolongement de l'autre pour obtenir ainsi un assemblage dans lequel le fil de couture est alors invisible de l'extérieur.By reverse stitched sewing means a seam 18 as illustrated in Figure 2 or Figure 5. In Figure 2, we see that the two parts to be assembled are sewn to each other at the folds turned inwards. One way to make such a seam is to place the two parts to be assembled against each other, the outer faces facing one another, and preferably edge to edge. Sewing is then performed, preferably along the edge of the two pieces, this seam being, for example, a conventional through-stitch. The two pieces are then unfolded to bring them one in line with the other to thereby obtain an assembly in which the sewing thread is then invisible from the outside.

Une fois assemblée, la tige ne montre, vue de l'extérieur, que les deux pièces de tiges qui se replient vers l'intérieur, en appui l'une contre l'autre.Once assembled, the stem shows, seen from the outside, only the two pieces of rods which fold inwards, resting against each other.

Grâce à cette construction, on peut voir que le fil de couture est protégé des frottements et autres agressions externes, ce qui en augmente la durée de vie. Cela est notamment important pour les coutures qui sont situées dans la partie basse de la chaussure, c'est-à-dire la partie située en dessous de la cheville de l'utilisateur, et encore plus particulièrement dans la zone de flexion métatarso-phalangienne.Thanks to this construction, we can see that the sewing thread is protected from friction and other external aggressions, which increases its life. This is particularly important for seams that are located in the lower part of the shoe, that is to say the part located below the user's ankle, and even more particularly in the metatarsophalangeal flexion area. .

De plus, on s'est aperçu qu'une telle couture résistait mieux à la pénétration de l'humidité dans la chaussure, humidité provenant de la pluie ou de la neige.In addition, it has been found that such a seam is more resistant to the penetration of moisture into the shoe, moisture from rain or snow.

L'assemblage par couture jointée retournée est particulièrement intéressant pour la jonction des pièces de la tige qui sont agencées sur l'extérieur de la tige, et qui sont donc à la fois visibles et sujettes aux frottements. Un tel assemblage est donc particulièrement intéressant pour un rabat de protection, mais il pourra aussi être utilisé pour d'autres pièces de la tige.The jointed seam assembly returned is particularly interesting for joining the parts of the rod which are arranged on the outside of the rod, and which are therefore both visible and subject to friction. Such an assembly is therefore particularly advantageous for a protective flap, but it can also be used for other parts of the rod.

Dans le mode de réalisation qui est illustré sur les figures 1 à 3 et qui vient d'être décrit ci-dessus, le matériau des deux pièces de la tige qui sont assemblées l'une à l'autre par la couture retournée sont du même ordre. Dans ce cas, on pourra généralement voir que les replis des pièces au niveau des coutures sont sensiblement à angles droits par rapport au plan des pièces assemblées.In the embodiment which is illustrated in FIGS. 1 to 3 and which has just been described above, the material of the two parts of the rod which are assembled to one another by the returned seam are of the same order. In this case, it will generally be seen that the folds of the parts at the seams are substantially at right angles to the plane of the assembled parts.

Le mode de réalisation qui est illustré sur les figures 4 et 5 comporte une tige 14 qui est munie d'un contrefort semi-rigide 30. Le contrefort 30 entoure le talon et peut se prolonger le long de la semelle jusqu'à la zone de flexion métatarso-phalangienne. On peut voir que la semelle 12 forme, au niveau du talon, un berceau relativement rigide qui recouvre partiellement le contrefort 30 par l'extérieur. Au voisinage de ce berceau relativement rigide, la face externe de la semelle est formée par le contrefort 30 dont la rigidité est intermédiaire entre la rigidité élevée du matériau de la semelle et celle, faible, du matériau de la claque 32 qui forme l'essentiel de la tige. Une telle construction est par exemple décrite dans la demande de brevet européen n° EP-787.441 auquel on se réfèrera utilement pour plus de détails. La semelle 12 est par exemple assemblée au contrefort semi-rigide par collage. Au contraire la claque 32 est assemblée au contrefort semi-rigide 30 par une couture qui, conformément aux enseignements de l'invention, est une couture jointée retournée 18.The embodiment which is illustrated in FIGS. 4 and 5 comprises a rod 14 which is provided with a semi-rigid stiffener 30. The buttress 30 surrounds the heel and can extend along the sole to the zone of metatarsophalangeal flexion. It can be seen that the sole 12 forms, at the heel, a relatively rigid cradle which partially covers the buttress 30 from the outside. In the vicinity of this relatively rigid cradle, the outer face of the sole is formed by the buttress 30 whose rigidity is intermediate between the high stiffness of the material of the sole and that of the material of the slab 32 which forms the essential of the stem. Such a construction is for example described in European Patent Application No. EP-787,441 which will be usefully referred to for more details. The sole 12 is for example assembled to the semi-rigid buttress by gluing. On the contrary, the slug 32 is assembled to the semi-rigid stiffener 30 by a seam which, according to the teachings of the invention, is an inverted joint seam 18.

Comme cela apparaît clairement sur la figure 5, le contrefort 30 étant plus rigide que la claque 32, il ne forme pas de repli dans la zone de la couture. Au contraire, la claque 32 est repliée sur elle-même à 180 degrés. Ici, on a donc une seule des pièces qui présente un repli au niveau de la couture retournée. Cependant, les avantages de la couture jointée retournée restent ici les mêmes que ceux décrits plus hauts. On remarque d'ailleurs que, le contrefort semi-rigide 30 étant en dessous de la claque 32, le repli à 180 degrés de la claque 32 forme un léger bourrelet qui s'étend verticalement en dessous du niveau de la couture proprement dite, laquelle se retrouve au sommet d'un recoin qui n'est ouvert que vers le bas. Le bourrelet protège donc la couture du ruissellement d'eau, à la manière d'une tuile.As clearly shown in Figure 5, the buttress 30 being more rigid than the slam 32, it does not form a fold in the area of the seam. On the contrary, the slap 32 is folded back on itself at 180 degrees. So here we have only one of the pieces that shows a decline in level of the seam returned. However, the advantages of the reverse stitched seam remain the same as those described above. Note also that, the semi-rigid buttress 30 being below the slam 32, the 180-degree fold of the slap 32 forms a slight bead which extends vertically below the level of the actual seam, which is at the top of a nook that is open only down. The bead thus protects the seam from water runoff, in the manner of a tile.
