Description

Chaussure avec une première de montage comprenant une planche avant en matériau souple  Shoe with a mounting first including a front board of flexible material
La présente invention a pour objet une chaussure présentant un confort et une flexibilité améliorés tout en conservant l'aspect visuel extérieur d'une chaussure classique, notamment dans le cas des chaussures à talon. The present invention relates to a shoe having improved comfort and flexibility while maintaining the external visual appearance of a classic shoe, especially in the case of heeled shoes.
Les quatre composants essentiels constituant le corps d'une chaussure sont les suivants :  The four essential components constituting the body of a shoe are the following:
a) la première de montage ou semelle intérieure  a) the first mounting or insole
Ce composant constitue le corps rigide de la chaussure, sur lequel la tige est montée. b) le talon  This component is the rigid body of the shoe on which the rod is mounted. b) the heel
c) la tige  c) the stem
La tige représente la partie visible de la chaussure, elle est refermée par de la colle et des clous sur la première de montage. Elle est en cuir, en tissu ou en toute autre matière synthétique. The stem represents the visible part of the shoe, it is closed by glue and nails on the first mounting. It is made of leather, fabric or any other synthetic material.
d) la semelle  d) the sole
Ce composant est un corps uniforme qui est collé, voire cousu sur la partie inférieure de la tige une fois que celle-ci a été montée sur la première de montage.  This component is a uniform body that is glued or even sewn on the lower part of the rod once it has been mounted on the first mounting.
Depuis l'apparition des chaussures à talon, leur procédé de fabrication n'a quasiment pas évolué. L'inconvénient majeur des chaussures à talon, plus  Since the appearance of heeled shoes, their manufacturing process has hardly changed. The major disadvantage of heeled shoes, more
particulièrement des chaussures à talon très haut, est leur manque de confort et de souplesse. especially high heel shoes, is their lack of comfort and flexibility.
Le but de l'invention est de fournir une chaussure à talon haut, notamment très haut, avec un confort et une flexibilité améliorés.  The object of the invention is to provide a high heel shoe, especially very high, with improved comfort and flexibility.
La première de montage est généralement réalisée à base de carton dur. Dans la majorité des cas, elle intègre le cambrion, une pièce en acier ou en matière plastique, permettant de donner de la fermeté à la cambrure de la chaussure et de soutenir la voûte plantaire. La première de montage est donc une pièce relativement rigide.  The first assembly is usually made from hardboard. In most cases, it incorporates the shank, a piece of steel or plastic, to give firmness to the arch of the shoe and support the arch. The first assembly is therefore a relatively rigid piece.
On a décrit dans le document EP0525324 un procédé de fabrication de chaussures dans lequel on forme une première de montage en assemblant par collage à l'aide d'un adhésif puissant une partie arrière rigide, par exemple en Texon avec un renfort en acier, et une partie avant souple, en cuir ou en un matériau analogue, dont les dimensions sont pratiquement égales aux dimensions de la chaussure.  EP0525324 describes a shoe manufacturing process in which a first assembly is formed by bonding with a strong adhesive a rigid rear part, for example made of Texon with a steel reinforcement, and a flexible front part, made of leather or a similar material, whose dimensions are practically equal to the dimensions of the shoe.
L'invention consiste à utiliser une première de montage bi-matière, c'est-à-dire que la planche avant est en matériau souple et la partie arrière est en matériau classique rigide. Ce matériau souple assure la liaison avec la partie arrière rigide de la première de montage et il recouvre au moins une partie de celle-ci. De cette manière, la première de montage peut se plier sans effort.  The invention consists in using a bi-material mounting first, that is to say that the front board is of flexible material and the rear part is of rigid conventional material. This flexible material provides the connection with the rigid rear portion of the first mounting and covers at least a portion thereof. In this way, the first mounting can bend effortlessly.
Le matériau souple peut être tout matériau flexible, par exemple un polymère, du caoutchouc ou une gomme ou un gel latex. Selon un mode de réalisation préféré, le matériau souple est une gomme latex injectée sur la partie arrière rigide de la première de montage. Plus particulièrement, il s'agit d'un polyuréthane thermoplastique. The flexible material may be any flexible material, for example a polymer, rubber or a latex gum or gel. According to a preferred embodiment, the flexible material is a latex rubber injected on the rigid rear part of the first mounting. More particularly, it is a thermoplastic polyurethane.
Selon un autre mode de réalisation préféré, le matériau souple est un polymère expansé injecté sur la partie arrière rigide de la première de montage. Plus  According to another preferred embodiment, the flexible material is an expanded polymer injected on the rigid rear part of the first mounting. More
particulièrement, il s'agit d'un polyuréthane expansé. particularly, it is an expanded polyurethane.
Dans le cas d'une chaussure à talon, le talon est généralement en matière plastique dure, par exemple en ABS, et on y insert une tige ou un tube en métal sur toute la longueur du talon. Cette pièce métallique assure la rigidité du talon.  In the case of a heeled shoe, the heel is generally made of hard plastic, for example ABS, and there is inserted a rod or a metal tube along the entire length of the heel. This metal piece ensures the stiffness of the heel.
Selon un mode de réalisation préféré, la tige est montée comme un mocassin, c'est-à-dire que sur la planche avant le matériau de la tige fait un tour complet comme une chaussette et entoure totalement le pied. On parle également de montage tubulaire. Ce système réservé traditionnellement aux mocassins offre une souplesse maximale en flexion.  According to a preferred embodiment, the rod is mounted as a moccasin, that is to say that on the front board the material of the rod makes a complete turn as a sock and completely surrounds the foot. We also speak of tubular assembly. This system traditionally reserved for moccasins offers maximum flexibility in flexion.
Selon encore un autre mode de réalisation, la semelle comporte, sur le périmètre intérieur de l'extrémité avant de la chaussure, un accessoire métallique antitorsion en forme de fer à cheval. Cet accessoire est placé entre la tige et la semelle, dans le cas d'un montage tubulaire de la tige, ou entre la première de montage et la semelle, dans le cas d'un montage classique de la tige. Ainsi, la chaussure reste bien à plat et ne se déforme pas ou ne s'avachit pas. En effet, la première de montage n'étant plus rigide sur la planche avant, l'accessoire anti-torsion évite le risque de cisaillement et de torsion.  According to yet another embodiment, the sole comprises, on the inner perimeter of the front end of the shoe, a metal accessory antitorsion shaped horseshoe. This accessory is placed between the rod and the sole, in the case of a tubular mounting of the rod, or between the first mounting and the sole, in the case of a conventional assembly of the rod. Thus, the shoe remains flat and does not deform or fail. Indeed, the first mounting is no longer rigid on the front board, the anti-torsion accessory avoids the risk of shearing and twisting.
Dans le cas des chaussures de luxe, la semelle est en cuir.  In the case of luxury shoes, the sole is leather.
De manière préférée, la semelle comporte au moins une incision transversale sur la totalité de la largeur de la planche avant. De préférence, elle est incisée en zigzag par exemple elle peut comporter 3 incisions de ce type.  Preferably, the sole comprises at least one transverse incision over the entire width of the front board. Preferably, it is incised zigzag for example it can include 3 incisions of this type.
On injecte ensuite sur la semelle une gomme polymère qui vient ainsi boucher ces incisions. Selon un mode de réalisation particulièrement préféré, on utilise deux polymères différents. Par exemple, on injecte sur le côté extérieur de la semelle un polyuréthane thermoplastique et sur le côté intérieur de la semelle, on injecte du poly (chlorure de vinyle).  Then injected on the sole a polymer gum which thus plug these incisions. According to a particularly preferred embodiment, two different polymers are used. For example, one injects on the outer side of the sole a thermoplastic polyurethane and on the inner side of the sole is injected poly (vinyl chloride).
Selon un autre mode de réalisation, la totalité de la semelle est en gomme polymère. On utilise alors, par exemple, du polyuréthane thermoplastique sur le côté extérieur de la semelle et du poly(chlorure de vinyle) sur le côté intérieur de la semelle.  According to another embodiment, the entire sole is made of polymeric gum. For example, thermoplastic polyurethane is used on the outer side of the sole and polyvinyl chloride on the inner side of the sole.
En variante, la chaussure selon l'invention est équipée à l'intérieur d'un fusbet ou première anatomique ou orthopédique. Cette pièce, moulée à partir de la forme de la chaussure, est à base de polymères plus ou moins denses et plus ou moins expansés. Par exemple, le fusbet peut être en caoutchouc hévéa ou en polyuréthane expansé. L'invention sera maintenant décrite plus en détail par référence aux dessins annexés. Alternatively, the shoe according to the invention is equipped inside a fusbet or first anatomical or orthopedic. This piece, molded from the shape of the shoe, is based on more or less dense polymers and more or less expanded. For example, the fusel may be rubber rubber or expanded polyurethane. The invention will now be described in more detail with reference to the accompanying drawings.
La figure 1 est une vue en coupe de la chaussure selon l'invention.  Figure 1 is a sectional view of the shoe according to the invention.
La figure 2 est une vue de dessous de la semelle de la chaussure selon l'invention.  Figure 2 is a bottom view of the sole of the shoe according to the invention.
La figure 3 est une vue de dessus de la semelle de la chaussure selon l'invention.  Figure 3 is a top view of the sole of the shoe according to the invention.
La figure 1 représente en coupe la chaussure selon l'invention, et plus particulièrement l'ensemble première de montage plus talon et semelle. La première de montage comprend une planche avant (1) en matériau souple injecté sur la partie arrière (2). La première de montage comprend de plus un cambrion (3). La première de montage est percée d'un trou (12) sur la partie arrière (2).  Figure 1 shows in section the shoe according to the invention, and more particularly the first set of mounting plus heel and sole. The first assembly comprises a front board (1) of flexible material injected on the rear portion (2). The first assembly further comprises a shank (3). The first mounting is pierced with a hole (12) on the rear portion (2).
Le talon (4) comprend une tige ou un tube de rigidification (5) soudé au cambrion (3). La tige de rigidification (5) débouche du talon au niveau du trou (12), ce qui permet le soudage de la tige (5) et du cambrion (3) afin de solidariser la première de montage et le talon (4). Le talon est également fixé à la première de montage à l'aide de plusieurs vis (13), par exemple trois vis.  The heel (4) comprises a rod or stiffening tube (5) welded to the shank (3). The stiffening rod (5) opens out of the heel at the hole (12), which allows the welding of the rod (5) and shank (3) to secure the first mounting and the heel (4). The heel is also attached to the first mounting with several screws (13), for example three screws.
Selon le mode de réalisation représenté sur la figure 1, la tige (6) est montée comme un mocassin.  According to the embodiment shown in Figure 1, the rod (6) is mounted as a moccasin.
Selon le mode de réalisation représenté sur la figure 1 , la semelle (7) est collée sur la planche avant, la cambrure et la gorge du talon. On parle alors d'un montage Louis XV.  According to the embodiment shown in Figure 1, the sole (7) is glued to the front board, the camber and throat of the heel. We are talking about a Louis XV montage.
Selon un mode de réalisation non représenté, la semelle (7) est collée sur la planche avant, la cambrure et sur 2 à 3 mm sous le talon. Dans ce cas, il s'agit d'un montage Bally.  According to an embodiment not shown, the sole (7) is glued to the front board, the camber and 2 to 3 mm under the heel. In this case, it is a Bally montage.
Au niveau de la planche avant, la semelle (7) comporte à l'extérieur des bandes de gomme polymère (8) injectée et à l'intérieur une zone de gomme polymère (11).  At the front board, the sole (7) has, on the outside, strips of injected polymeric gum (8) and, inside, a zone of polymeric gum (11).
Un accessoire anti -torsion (10) est placé entre la tige (6) et la semelle (7). Selon un mode de réalisation préféré de l'invention, la partie arrière (2) de la première de montage est en carton dur, tel que du carton dur moulé, par exemple en Texon 2000. On utilise particulièrement le carton rouge ou le carton beige naturel. Le matériau souple de la planche avant (1) est de préférence un polyuréthane  An anti-torsion accessory (10) is placed between the rod (6) and the sole (7). According to a preferred embodiment of the invention, the rear part (2) of the first mounting is made of hard cardboard, such as molded hardboard, for example made of Texon 2000. Red card or beige cardboard is particularly used. natural. The flexible material of the front board (1) is preferably a polyurethane
thermoplastique ou un polyuréthane expansé. Le cambrion (3) est de préférence en acier. Le talon (4) est en matière plastique dure, par exemple en ABS, et la tige de rigidification (5) du talon (4) est en acier. thermoplastic or expanded polyurethane. The shank (3) is preferably made of steel. The heel (4) is made of hard plastic, for example ABS, and the stiffening rod (5) of the heel (4) is made of steel.
La semelle (7) est de préférence en cuir. Au niveau de la planche avant, les bandes de gomme polymère (8) injectée sont, plus particulièrement, en polyuréthane thermoplastique. La figure 2 représente une vue de dessous de la semelle de la chaussure selon l'invention. La semelle (7) comporte, au niveau de la planche avant, des incisions transversales (9) sur la totalité de la largeur de la semelle (7). De préférence, la semelle est incisée en zigzag (9) et les incisions sont faites sur la partie arrière de la planche avant. Ces incisions (9) sont comblées par injection de la gomme polymère (8). La gomme polymère, de préférence un polyuréthane thermoplastique, procure une meilleure flexibilité et donne à la semelle (7) en cuir de la souplesse, ce qui évite que la semelle force à la pliure. The sole (7) is preferably leather. At the front board, the strips of polymer gum (8) injected are, more particularly, thermoplastic polyurethane. Figure 2 shows a bottom view of the sole of the shoe according to the invention. The sole (7) comprises, at the front board, transverse incisions (9) over the entire width of the sole (7). Preferably, the sole is incised in zigzag (9) and the incisions are made on the rear part of the front board. These incisions (9) are filled by injection of the polymeric gum (8). The polymeric gum, preferably a thermoplastic polyurethane, provides greater flexibility and gives the leather sole (7) flexibility, which prevents the sole from crimping.
La figure 3 représente une vue de dessus de la semelle de la chaussure selon l'invention. La semelle (7) comporte, sur le périmètre intérieur de l'extrémité avant de la chaussure, un accessoire anti -torsion (10) en forme de fer à cheval. Etant donné que la première de montage n'est plus rigide au niveau de la planche avant, cet accessoire (10) évite le risque de cisaillement et de torsion. De cette manière, la chaussure reste bien à plat et ne se déforme pas ou ne s'avachit pas. L'accessoire anti-torsion (10) est une lame fine en un matériau rigide. Ce matériau est de préférence un métal qui ne se déforme pas, tel que l'acier, le fer, du carbone ou une matière plastique rigide. L'accessoire antitorsion (10) est de préférence collé sur la semelle, celle-ci étant légèrement rabotée sur 1 ou 2 mm.  Figure 3 shows a top view of the sole of the shoe according to the invention. The sole (7) has, on the inner perimeter of the front end of the shoe, an anti-retaliation accessory (10) shaped horseshoe. Since the mounting first is no longer rigid at the front board, this accessory (10) avoids the risk of shearing and twisting. In this way, the shoe remains flat and does not deform or fail. The anti-twist accessory (10) is a thin blade of rigid material. This material is preferably a non-deforming metal, such as steel, iron, carbon or a rigid plastic material. The anti-torsion accessory (10) is preferably glued to the sole, the latter being slightly planed to 1 or 2 mm.
L'intérieur de la semelle comporte, au niveau de la partie arrière de la planche avant, une zone de gomme polymère (11). Cette gomme est de préférence du  The interior of the sole comprises, at the rear portion of the front board, a zone of polymer gum (11). This gum is preferably
poly(chlorure de vinyle). La gomme est injectée du côté intérieur de la semelle et on l'étalé pour qu'elle reste bien en place. Le poly(chlorure de vinyle) adhère bien au cuir de la semelle (7). On obtient ainsi une bonne étanchéité ainsi qu'une impression d'amortisseur pour le pied, qui repose à environ 70% sur cette partie de la semelle. polyvinyl chloride. The rubber is injected on the inside of the sole and spread out to keep it in place. Poly (vinyl chloride) adheres well to the leather of the sole (7). This provides a good seal and a cushioning impression for the foot, which rests about 70% on this part of the sole.
Selon un mode de réalisation non représenté, on remplace la semelle en cuir par une semelle entièrement en gomme. De préférence, la semelle comporte alors un tapissage de mousse chlorophylle sur le côté intérieur. La mousse chlorophylle a un effet antiallergique, anti-acarien et/ou antifongique.  According to an embodiment not shown, the leather sole is replaced by a sole entirely made of rubber. Preferably, the sole then comprises a lining of chlorophyll foam on the inner side. Chlorophyll foam has an antiallergic, anti-mite and / or antifungal effect.
Selon un autre mode de réalisation non représenté, la chaussure comprend de plus un fusbet. Ce fusbet est moulé à partir de la forme de la chaussure, comme une empreinte de pied. Le fusbet est en polymère plus ou moins dense, plus ou moins expansé, l'air apportant de la légèreté. A titre d'exemple, le fusbet peut être en caoutchouc hévéa ou en polyuréthane expansé.  According to another embodiment not shown, the shoe further comprises a fusbet. This fusbet is molded from the shape of the shoe, like a footprint. The fusbet is more or less dense polymer, more or less expanded, air bringing lightness. By way of example, the fuset may be rubber rubber or expanded polyurethane.
Le procédé de fabrication de la chaussure selon l'invention comprend plusieurs étapes :  The method of manufacturing the shoe according to the invention comprises several steps:
a) on prépare la première de montage en injectant un polymère, une gomme latex ou un gel latex sur une première de montage classique rigide, qui a été découpée de manière à supprimer la portion représentant la planche avant ; b) on perce un trou dans la partie rigide de la première de montage, en regard de la tige en acier rigidifiant le talon et on insère le cambrion dans la première de montage ; a) preparing the first assembly by injecting a polymer, a latex gum or a latex gel onto a rigid conventional mounting first, which has been cut to remove the portion representing the front board; b) drilled a hole in the rigid portion of the first mounting, opposite the steel rod stiffening the heel and inserting the shank in the first mounting;
c) on réalise un montage tubulaire de la tige sur la première de montage ; d) on fixe le talon en vissant de 2 à 5 vis dans le talon puis on soude la tige de rigidification et le cambrion ;  c) tubular mounting of the rod on the first mounting; d) the heel is fixed by screwing 2 to 5 screws in the heel and then welding the stiffening rod and the shank;
e) enfin, on colle la semelle sur la planche avant, la cambrure et la gorge du talon.  e) Finally, glue the sole on the front board, the arch and the throat of the heel.
Ce procédé est utilisé pour un montage Louis XV. Dans le cas d'un montage Bally, après l'étape c), on colle la semelle sur la planche avant et la cambrure de manière à ce que 2 à 3 mm de la semelle passent sous le talon, on fixe ensuite le talon en vissant de 2 à 5 vis dans le talon puis on soude la tige de rigidification et le cambrion.  This process is used for a Louis XV montage. In the case of a Bally assembly, after step c), the sole is glued on the front board and the camber so that 2 to 3 mm of the sole pass under the heel, the heel is then fixed in screwing 2 to 5 screws in the heel and then welding the stiffening rod and the shank.
