  • an outer sole and a footwear element This element itself comprises an envelope, which is part of the upper of the shoe, and an insole, which may be a first or a first of the Strobel type according to the technique used.
  • the first mounting sole is secured to the envelope by gluing, while that of the Strobel type is secured by stitching.
  • the footwear element obtained is secured to the outer sole by appropriate means such as gluing, interlocking, or the like.
  • a sockliner is disposed inside the footwear element, so as to cover the first mounting sole or Strobel type. It is common that the insole also covers the junction between the first mounting plate, or Strobel type, and the envelope.
  • the invention provides a shoe comprising the features of claim 1.
  • the shoe comprises an outer sole and a rod, the shoe extending in length from a rear end to a front end, in width between one side lateral and medial side, and in height from the outer sole to an upper end, the shoe comprising a first footwear element, the first footwear element comprising an inner sole, a lateral quarter, and a medial quarter.

  • This surface portion may be internal to the footwear element, that is to say able to contact the foot. It follows that the contact between the foot and the footwear element, and consequently between the foot and the upper, is more regular than in a shoe according to the prior art. This is why the boot according to the invention is advantageously more comfortable.

Description

La présente description se rapporte à des chaussures de marche ou de sport, et concerne plus spécialement des chaussures pour évoluer sur terrain plat ou en montagne, pour utiliser une planche à roues, une planche de surf sur neige, des skis ou des raquettes à neige, pour pratiquer un sport de balle, ou autre. L'invention concerne des chaussures présentant l'aspect général d'une tong. Pour fabriquer des chaussures adaptées à ces pratiques, il est connu d'utiliser un semelage externe et un élément chaussant. Cet élément comprend lui-même une enveloppe, qui fait partie de la tige de la chaussure, et une semelle interne, laquelle peut être une première de montage ou une première de type Strobel selon la technique employée. Bien entendu la semelle première de montage est solidarisée à l'enveloppe par collage, alors que celle de type Strobel l'est par couture. Dans tous les cas l'élément chaussant obtenu est solidarisé au semelage externe par un moyen approprié, comme un collage, un emboîtement, ou autre.The present description relates to walking or sports shoes, and more particularly to shoes for moving on flat terrain or in the mountains, to use a wheeled board, snow board, skis or snowshoes , to practice a ball sport, or whatever. The invention relates to shoes having the general appearance of a flip-flop. To manufacture shoes adapted to these practices, it is known to use an outer sole and a footwear element. This element itself comprises an envelope, which is part of the upper of the shoe, and an insole, which may be a first or a first of the Strobel type according to the technique used. Of course, the first mounting sole is secured to the envelope by gluing, while that of the Strobel type is secured by stitching. In all cases, the footwear element obtained is secured to the outer sole by appropriate means such as gluing, interlocking, or the like.

Afin de conférer à la chaussure un niveau de confort satisfaisant, une semelle première de propreté est disposée à l'intérieur de l'élément chaussant, de façon à couvrir la semelle première de montage ou de type Strobel. Il est fréquent que la semelle première de propreté couvre aussi la jonction entre la semelle première de montage, ou de type Strobel, et l'enveloppe.In order to give the shoe a satisfactory level of comfort, a sockliner is disposed inside the footwear element, so as to cover the first mounting sole or Strobel type. It is common that the insole also covers the junction between the first mounting plate, or Strobel type, and the envelope.

Ainsi dans la majorité des cas la chaussure obtenue est satisfaisante, notamment dans le sens où elle apporte au pied un certain confort. On a néanmoins observé quelques inconvénients.Thus in most cases the shoe obtained is satisfactory, especially in the sense that it gives the foot a certain comfort. Nevertheless, some disadvantages have been observed.

Par exemple, lors d'une utilisation extrême ou prolongée, des petits traumatismes peuvent apparaître au niveau du pied d'un utilisateur. En effet, il peut arriver par exemple que la semelle première de propreté se déplace de manière intempestive dans l'élément chaussant. Il arrive aussi parfois que le contact entre le pied d'un utilisateur et l'élément chaussant ne soit pas uniforme. Au final, même lorsqu'il est correct, le confort n'est pas maximal.For example, during extreme or prolonged use, small trauma may appear on the foot of a user. Indeed, it may happen for example that the insole first moves unintentionally in the footwear element. It also happens sometimes that the contact between the foot of a user and the footwear is not uniform. In the end, even when it is correct, the comfort is not maximum.

Un autre inconvénient des chaussures évoquées avant est celui de leur relative complexité. Celle-ci se mesure d'abord dans le sens où il faut plusieurs semelles différentes pour former le semelage complet, plusieurs pièces telles que des quartiers, un contrefort, une empeigne, ou une languette pour former l'enveloppe de l'élément chaussant. En d'autres termes il faut beaucoup de pièces pour fabriquer la chaussure. Par voie de cause à effet la complexité se mesure aussi par l'abondance de l'outillage nécessaire à la préparation des pièces, par le temps nécessaire à l'assemblage, ou encore par la nature complexe du travail d'assemblage. On remarque en parallèle que la complexité augmente le prix de revient. US 2 947 095 A dévoile une chaussure de type tong comprenant un semelage externe et une tige, et un premier élément chaussant comprenant un semelage interne, un quartier latéral et un quartier médial. L'un des buts de l'invention est d'améliorer le confort d'une chaussure de type tong. Un autre but est de réduire la complexité de la chaussure, selon une déclinaison la plus large possible.Another disadvantage of shoes mentioned before is that of their relative complexity. This is measured first in the sense that it takes several different soles to form the complete sole, several parts such as quarters, a buttress, a vamp, or a tongue to form the envelope of the footwear element. In other words it takes a lot of parts to make the shoe. By way of cause and effect complexity is also measured by the abundance of tools required for the preparation of parts, the time required for assembly, or by the complex nature of the assembly work. We note in parallel that complexity increases the cost price. US 2,947,095 A discloses a thong type shoe comprising an outer sole and a shaft, and a first footwear element comprising an inner sole, a side quarter and a medial quarter. Mon aims of the invention is to improve the comfort of a flip-type shoe. Another goal is to reduce the complexity of the shoe, according to the widest possible variation.

Pour ce faire l'invention propose une chaussure comprenant les caractéristiques de la revendication 1. La chaussure comprend un semelage externe et une tige, la chaussure s'étendant en longueur depuis une extrémité arrière jusqu'à une extrémité avant, en largeur entre un côté latéral et un côté médial, et en hauteur depuis le semelage externe jusqu'à une extrémité supérieure, la chaussure comprenant un premier élément chaussant, le premier élément chaussant comprenant un semelage interne, un quartier latéral, et un quartier médial. Le semelage interne, le quartier latéral et le quartier médial du premier élément chaussant forment une pièce monobloc.To do this, the invention provides a shoe comprising the features of claim 1. The shoe comprises an outer sole and a rod, the shoe extending in length from a rear end to a front end, in width between one side lateral and medial side, and in height from the outer sole to an upper end, the shoe comprising a first footwear element, the first footwear element comprising an inner sole, a lateral quarter, and a medial quarter. The inner sole, the lateral quarter and the medial area of the first footwear element form a one-piece piece.

Il apparaît que le semelage interne, le quartier latéral et le quartier médial sont associés les uns aux autres, en partie au moins par continuité de matière. En conséquence l'élément chaussant présente au moins une portion de surface continue qui s'étend à la fois au niveau du semelage interne, du quartier latéral et du quartier médial. Cette portion de surface peut être interne à l'élément chaussant, c'est-à-dire apte à contacter le pied. Il s'ensuit que le contact entre le pied et l'élément chaussant, et par voie de conséquence entre le pied et la tige, est plus régulier que dans une chaussure selon l'art antérieur. C'est pourquoi la chaussure selon l'invention est avantageusement plus confortable. La continuité de contact optimise la répartition des pressions sur le pied.It appears that the internal sole, the lateral quarter and the medial quarter are associated with each other, partly at least by continuity of matter. As a result, the footwear element has at least one portion of a continuous surface that extends both at the level of the internal sole, the lateral quarter and the medial area. This surface portion may be internal to the footwear element, that is to say able to contact the foot. It follows that the contact between the foot and the footwear element, and consequently between the foot and the upper, is more regular than in a shoe according to the prior art. This is why the boot according to the invention is advantageously more comfortable. The continuity of contact optimizes the distribution of pressure on the foot.

Par ailleurs, puisque le semelage interne, le quartier latéral et le quartier médial forment une pièce monobloc, le nombre de pièces constitutives de la chaussure est réduit, par rapport à une chaussure équivalente selon l'art antérieur. C'est pourquoi dans l'invention la chaussure nécessite un outillage réduit, un nombre d'opérations réduit, et une durée d'assemblage plus courte. Le travail d'assemblage est donc plus simple. De manière générale la chaussure selon l'invention est avantageusement plus simple qu'une chaussure selon l'art antérieur. On observe par corollaire que la chaussure selon l'invention est peu onéreuse à fabriquer.Moreover, since the inner sole, the lateral quarter and the medial quarter form a single piece, the number of component parts of the shoe is reduced, compared to an equivalent shoe according to the prior art. This is why in the invention the shoe requires reduced tooling, a reduced number of operations, and a shorter assembly time. Assembly work is therefore simpler. In general, the boot according to the invention is advantageously simpler than a shoe according to the prior art. It is observed as a corollary that the shoe according to the invention is inexpensive to manufacture.

La première forme de réalisation concerne notamment des chaussures pour une marche décontractée, par exemple en ville ou sur un sol assez régulier.The first embodiment concerns in particular shoes for a relaxed walk, for example in town or on a fairly regular floor.

La première forme de réalisation est décrite ci-après à l'aide des figures 1 à 6.The first embodiment is described below using the Figures 1 to 6 .

Comme le montre la figure 1, une chaussure de marche 1 est prévue pour accueillir le pied de l'utilisateur. De manière connue, la chaussure 1 comprend un semelage externe 2 et une tige 3 disposée sur ce semelage. La chaussure s'étend en longueur, selon une direction longitudinale L, entre une extrémité arrière ou talon 4 et une extrémité avant ou pointe 5, et en largeur, selon une direction transversale W, entre un côté latéral 6 et un côté médial 7.As shown in figure 1 , a walking shoe 1 is provided to accommodate the foot of the user. In known manner, the shoe 1 comprises an outer sole 2 and a rod 3 disposed on this sole. The shoe extends in length, in a longitudinal direction L, between a rear end or heel 4 and a front end or tip 5, and in width, in a transverse direction W, between a lateral side 6 and a medial side 7.

Telle que représentée la tige 3 comprend seulement une portion basse 10, prévue pour entourer le pied, à l'exclusion de toute portion haute. Cependant, il pourrait être envisagé alternativement une tige comprenant une portion basse et une portion haute.As shown in the rod 3 comprises only a lower portion 10, provided to surround the foot, excluding any high portion. However, it could alternatively be considered a rod comprising a low portion and a high portion.

Selon la première forme de réalisation décrite, la chaussure 1 s'étend en hauteur depuis le semelage externe 2 jusqu'à un dessus 12, c'est-à-dire jusqu'à l'extrémité libre de la portion basse 10 ou de la tige 3.According to the first embodiment described, the shoe 1 extends in height from the outer sole 2 up to a top 12, that is to say up to the free end of the lower portion 10 or the stem 3.

La chaussure 1 est structurée pour permettre un bon déroulement du pied pendant la marche, des transmissions d'informations sensorielles, et des impulsions pour des appuis ou des réceptions. C'est pourquoi le semelage externe 2 et la tige 3 sont souples, ou relativement souples.The shoe 1 is structured to allow a smooth running of the foot during walking, transmissions of sensory information, and impulses for support or receptions. This is why the outer sole 2 and the rod 3 are flexible, or relatively flexible.

On remarque que la chaussure 1 est dépourvue de dispositif de serrage de la tige 3. En effet, comme on le percevra mieux après, la chaussure est conformée pour épouser fidèlement le pied, à la manière d'une deuxième peau. C'est pourquoi la tige 3 est continue depuis le côté latéral 6 jusqu'au côté médial 7. Cependant, dans certains cas la chaussure 1 pourrait comprendre un dispositif de serrage de la tige 3, sans sortir de l'esprit de l'invention.Note that the shoe 1 is devoid of clamping device of the rod 3. Indeed, as will be seen better after, the shoe is shaped to marry faithfully the foot in the manner of a second skin. This is why the rod 3 is continuous from the side Lateral 6 to the medial side 7. However, in some cases the shoe 1 could include a clamping device of the rod 3, without departing from the spirit of the invention.

De manière non limitative, la chaussure 1 comprend un élément chaussant unique 15. Cela signifie que cet élément 15 délimite à la fois l'extérieur et l'intérieur de la tige 3, l'intérieur correspondant au volume d'accueil du pied. A ce titre, l'élément chaussant 15 comprend un semelage interne 16, un quartier latéral 17, et un quartier médial 18. Le semelage interne 16, le quartier latéral 17 et le quartier médial 18 forment une pièce monobloc. Le semelage interne 16, le quartier latéral 17 et le quartier médial 18 sont associés les uns aux autres, en partie au moins par continuité de matière. C'est pourquoi l'élément chaussant 15 présente au moins une portion de surface continue 19 qui s'étend à la fois au niveau du semelage interne 16, du quartier latéral 17, et du quartier médial 18. Cela rend la chaussure 1 plus confortable. La portion de surface continue 19 est située au niveau de la voûte plantaire.In a nonlimiting manner, the shoe 1 comprises a single footwear element 15. This means that this element 15 delimits both the outside and the inside of the upper 3, the inside corresponding to the reception volume of the foot. As such, the footwear element 15 comprises an internal sole 16, a lateral quarter 17, and a medial quarter 18. The internal sole 16, the lateral quarter 17 and the medial quarter 18 form a single piece. The internal sole 16, the lateral quarter 17 and the medial quarter 18 are associated with each other, at least partly by continuity of material. This is why the footwear element 15 has at least one continuous surface portion 19 which extends at the same time at the level of the internal sole 16, the lateral quarter 17, and the medial quarter 18. This makes the shoe 1 more comfortable . The continuous surface portion 19 is located at the level of the arch.

Comme on le comprend à l'aide des figures 2 et 3, l'élément chaussant 15 est obtenu par patronage à plat. Cela signifie que, avant que la chaussure 1 ne prenne sa forme en trois dimensions, un patron 20 en deux dimensions délimite l'élément chaussant 15, à savoir le semelage interne 16, le quartier latéral 17 et le quartier médial 18. Ces trois parties 16, 17, 18 sont donc contenues dans un même plan lors d'une étape originelle de fabrication. A ce stade le semelage interne 16 est disposé entre le quartier latéral 17 et le quartier médial 18 transversalement. Autrement dit, le semelage interne 16 sépare les quartiers 17, 18 selon la direction transversale W de la chaussure 1.As we understand it with the help of Figures 2 and 3 , the footwear element 15 is obtained by flat patterning. This means that, before the boot 1 takes on its three-dimensional shape, a two-dimensional pattern 20 delimits the footwear element 15, namely the inner sole 16, the lateral quarter 17 and the medial quarter 18. These three parts 16, 17, 18 are contained in the same plane during an original stage of manufacture. At this stage the internal assembly 16 is disposed between the lateral quarter 17 and the medial quarter 18 transversely. In other words, the inner soleing 16 separates the quarters 17, 18 in the transverse direction W of the boot 1.

Le semelage interne 16 s'étend en longueur, selon la direction longitudinale L, depuis une extrémité arrière 24 jusqu'à une extrémité avant 25. Chacune des extrémités 24, 25 est convexe, pour suivre le contour du talon ou des orteils comme on le verra mieux après. Le semelage interne 16 s'étend en largeur, selon la direction transversale W, entre un bord latéral 26 et un bord médial 27 du côté de l'extrémité avant 25, et entre une frontière latérale 28 et une frontière médiale 29 du côté de l'extrémité arrière 24. En fait le premier élément chaussant 15 présente une continuité de matière entre le semelage interne 16 et le quartier latéral 17, la continuité de matière formant la frontière latérale 28. Par analogie le premier élément chaussant 15 présente une continuité de matière entre le semelage interne 16 et le quartier médial 18, la continuité de matière formant la frontière médiale 29. On remarque que les bords latéral 26 et médial 27 sont en vis-à-vis transversalement, et que les frontières latérale 28 et médiale 29 sont aussi en vis-à-vis transversalement. Il va de soi que le bord latéral 26 et la frontière latérale 28 se prolongent l'un l'autre, selon la direction longitudinale L. Dans le même esprit le bord médial 27 et la frontière médiale 29 se prolongent l'un l'autre, selon la direction longitudinale L. Cela signifie que, respectivement, le bord latéral 26 et la frontière latérale 28 sont dans la continuité l'un de l'autre, et que le bord médial 27 et la frontière médiale 29 sont dans la continuité l'un de l'autre.The internal sizing 16 extends in length, in the longitudinal direction L, from a rear end 24 to a front end 25. Each of the ends 24, 25 is convex, to follow the contour of the heel or toes as it is will see better after. The internal sizing 16 extends in width, in the transverse direction W, between a lateral edge 26 and a medial edge 27 on the side of the front end 25, and between a lateral border 28 and a medial border 29 on the lateral side. 24. In fact the first footwear element 15 has a continuity of material between the internal sole 16 and the lateral quarter 17, the continuity of material forming the lateral border 28. By analogy the first footwear element 15 has a continuity of material between the internal sole 16 and the medial quarter 18, the continuity of material forming the medial border 29. It is noted that the lateral 26 and medial edges 27 are vis-à-vis transversely, and that the lateral 28 and medial 29 borders are also vis-à-vis transversely. It goes without saying that the lateral edge 26 and the lateral border 28 extend one another in the longitudinal direction L. In the same spirit the medial edge 27 and the medial border 29 extend one another along the longitudinal direction L. This means that, respectively, the lateral edge 26 and the lateral border 28 are in continuity with one another, and that the medial edge 27 and the medial border 29 are in continuity with each other. one of the other.

Afin de faciliter la description du patron 20, on définit quatre zones spécifiques 31, 32, 33, 34 du semelage interne 16. Ainsi ce dernier 16 présente successivement, depuis son extrémité arrière 24 jusqu'à son extrémité avant 25, quatre zones qui sont : une zone d'extrémité arrière 31 ou zone de talon, prévue pour supporter le talon du pied, une première zone intermédiaire 32, prévue pour supporter la voute plantaire, une deuxième zone intermédiaire 33, prévue pour supporter le métatarse, et enfin une zone d'extrémité avant 34 ou zone de pointe, prévue pour supporter les orteils.In order to facilitate the description of the pattern 20, four specific zones 31, 32, 33, 34 of the internal sole formation 16 are defined. Thus the latter 16 successively presents, from its rear end 24 to its front end 25, four zones which are : a rear end zone 31 or heel area, designed to support the heel of the foot, a first intermediate zone 32, designed to support the plantar arch, a second intermediate zone 33, designed to support the metatarsal, and finally a zone front end 34 or tip area, provided to support the toes.

Pour former le patron 20, ou l'élément chaussant 15, le quartier latéral 17 prolonge le semelage interne 16 transversalement, dans un sens d'éloignement de la frontière latérale 28, cette dernière 28 s'étendant le long de la première zone intermédiaire 32 du semelage interne 16. Dans le même esprit le quartier médial 18 prolonge le semelage interne 16 transversalement, dans un sens d'éloignement de la frontière médiale 29, cette dernière 29 s'étendant le long de la première zone intermédiaire 32 du semelage interne 16.To form the boss 20, or the footwear element 15, the lateral quarter 17 extends the inner sole 16 transversely, in a direction away from the lateral border 28, the latter 28 extending along the first intermediate zone 32 In the same spirit, the medial quarter 18 extends the internal sizing 16 transversely, in a direction away from the medial border 29, the latter 29 extending along the first intermediate zone 32 of the internal sole 16 .

Chacun des quartiers 17, 18 s'étend aussi vers l'avant. Ainsi le quartier latéral 17 présente un bord inférieur avant 41, convexe, prévu pour être solidarisé au bord latéral 26 du semelage 16. Le bord inférieur 41 prend sa source à la jonction du bord latéral 26 et de la frontière latérale 28. En conséquence le patron 20 présente une échancrure latérale avant 42, qui s'évase vers l'avant 5, entre les bords latéral 26 et inférieur 41. Dans le même esprit le quartier médial 18 présente un bord inférieur avant 43, convexe, prévu pour être solidarisé au bord médial 27 du semelage 16. Le bord inférieur 43 prend sa source à la jonction du bord médial 27 et de la frontière médiale 29. En conséquence le patron 20 présente une échancrure médiale avant 44, qui s'évase vers l'avant 5, entre les bords médial 27 et inférieur 43.Each of the quarters 17, 18 also extends forward. Thus, the lateral portion 17 has a convex front lower edge 41 intended to be secured to the lateral edge 26 of the sole assembly 16. The lower edge 41 has its source at the junction of the lateral edge 26 and the lateral border 28. boss 20 has a front lateral notch 42, which flares forward 5, between the lateral edges 26 and lower 41. In the same spirit the medial quarter 18 has a front lower edge 43, convex, provided to be secured to the the medial edge 27 of the sole 16. The lower edge 43 has its source at the junction of the medial edge 27 and the medial border 29. As a result the boss 20 has a medial notch before 44, which flares forward 5, between the medial 27 and lower 43 edges.

Vers l'arrière le quartier latéral 17 présente un bord arrière 51, concave, prévu pour délimiter une entrée de chaussage. Le bord arrière 51 prend sa source à la jonction de l'extrémité arrière 24 et de la frontière latérale 28. On remarque que l'extrémité arrière 24 et le bord arrière 51 se prolongent l'un l'autre. Dans le même esprit le quartier médial 18 présente un bord arrière 53, concave, prévu pour délimiter une entrée de chaussage. Le bord arrière 53 prend sa source à la jonction de l'extrémité arrière 24 et de la frontière médiale 29. L'extrémité arrière 24 et le bord arrière 53 se prolongent l'un l'autre. Au final, à l'arrière 4 du patron 20, l'extrémité 24 est en saillie selon la direction longitudinale L.Toward the rear side 17 has a rear edge 51, concave, intended to delimit a boot entry. The rear edge 51 has its source at the junction of the rear end 24 and the lateral border 28. Note that the rear end 24 and the rear edge 51 extend to each other. In the same spirit the medial quarter 18 has a concave rear edge 53, intended to delimit a boot entry. The trailing edge 53 has its source at the junction of the rear end 24 and the medial border 29. The rear end 24 and the trailing edge 53 extend to each other. Finally, at the rear 4 of the boss 20, the end 24 is projecting in the longitudinal direction L.

Afin de décrire la totalité du périmètre du patron 20, on précise que le quartier latéral 17 présente un bord supérieur 55, lequel relie le bord inférieur 41 au bord arrière 51. Dans le même esprit le quartier médial 18 présente un bord supérieur 56, lequel relie le bord inférieur 43 au bord arrière 53. Chacun des bords supérieurs 55, 56 s'étend selon la direction longitudinale L, à hauteur de la première zone intermédiaire 32, de la deuxième zone intermédiaire 33, et de la zone avant 34.In order to describe the entire perimeter of the pattern 20, it is specified that the lateral portion 17 has an upper edge 55, which connects the lower edge 41 to the rear edge 51. In the same spirit the medial quarter 18 has an upper edge 56, which connects the lower edge 43 to the rear edge 53. Each of the upper edges 55, 56 extends in the longitudinal direction L, at the height of the first intermediate zone 32, the second intermediate zone 33, and the front zone 34.

De manière non limitative, comme on le comprend à l'aide de la figure 3, le patron 20 présente une épaisseur e qui peut être constante ou variable. Cela revient à dire que l'élément chaussant 15 présente, pour au moins 80% de son étendue, une épaisseur e comprise entre 0,8 et 10 mm, sachant que des valeurs de 1,5 à 4 mm ont donné de bons résultats. Selon la forme de réalisation décrite, l'épaisseur e est par exemple choisie constante. On remarque que, selon la première forme de réalisation décrite, l'élément chaussant 15 comprend deux couches superposées 59, 60. Par exemple la première couche 59 est une couche structurelle ou enveloppe prévue, comme on le comprendra mieux après, pour être solidarisée au semelage externe 2 et pour délimiter l'extérieur de la tige 3. La deuxième couche 60, quant à elle, est une doublure destinée à contacter le pied et, de ce fait, délimite l'intérieur de la tige 3.In a non-limiting way, as is understood by means of the figure 3 , the pattern 20 has a thickness e which can be constant or variable. That is to say that the footwear element 15 has, for at least 80% of its extent, a thickness e of between 0.8 and 10 mm, knowing that values of 1.5 to 4 mm have given good results. According to the embodiment described, the thickness e is for example chosen constant. Note that, according to the first embodiment described, the footwear element 15 comprises two superimposed layers 59, 60. For example, the first layer 59 is a structural layer or envelope provided, as will be better understood later, to be secured to the external sole 2 and to define the outside of the rod 3. The second layer 60, for its part, is a lining intended to contact the foot and, as a result, delimits the inside of the rod 3.

Les première 59 et deuxième 60 couches sont assemblées l'une contre l'autre, par exemple par collage, et forment un matériau lamifié. L'épaisseur de l'enveloppe 59 est égale ou supérieure à l'épaisseur de la doublure 60.The first 59 and second 60 layers are assembled against each other, for example by gluing, and form a laminated material. The thickness of the envelope 59 is equal to or greater than the thickness of the liner 60.

Il est bien entendu que le nombre de couches de l'élément chaussant n'est pas limité, et qu'il peut être de deux ou plus.It is understood that the number of layers of the footwear element is not limited, and that it can be two or more.

De manière non limitative, il est prévu que l'enveloppe 59 donne à l'élément chaussant 15 sa résistance mécanique. Autrement dit, l'élément chaussant 15 présente une structure autoporteuse, uniforme dans ses propriétés mécaniques, comme la résistance à la traction, ou autre. L'enveloppe 59 est par exemple réalisée en EVA, acronyme d'éthyle-vinyle-acétate, en polyuréthane, ou tout équivalent. La doublure 60 quand à elle apporte un certain confort. La doublure 60 peut être constituée d'un tissu, ou de tout équivalent.Without limitation, it is expected that the envelope 59 gives the footwear element 15 its mechanical strength. In other words, the footwear element 15 has a self-supporting structure, uniform in its mechanical properties, such as tensile strength, or other. The envelope 59 is for example made of EVA, acronym of ethyl-vinyl-acetate, polyurethane, or any equivalent. The lining 60 when it brings a certain comfort. The liner 60 may be fabric, or any equivalent.

L'architecture du patron 20 ci-avant présentée permet l'obtention de l'élément chaussant 15, montré notamment sur les figures 4 et 5. Sur ces figures le patron 20, en deux dimensions, a donné naissance à l'élément chaussant 15, en trois dimensions. Cela signifie bien sûr que l'on est passé d'une pièce plate à un objet tridimensionnel.The architecture of the boss 20 presented above makes it possible to obtain the footwear element 15, shown in particular on the Figures 4 and 5 . In these figures the boss 20, in two dimensions, gave rise to the footwear element 15, in three dimensions. This of course means that we went from a flat piece to a three-dimensional object.

On observe que le quartier latéral 17 s'étend en avant de la frontière latérale 28, un moyen de solidarisation permanente 61 reliant le quartier latéral 17 au semelage interne 16 en avant de la frontière latérale 28. On observe également que le quartier médial 18 s'étend en avant de la frontière médiale 29, un moyen de solidarisation permanente 62 reliant le quartier médial 18 au semelage 16 en avant de la frontière médiale 29. On observe enfin qu'un moyen de solidarisation permanente 63 relie le quartier latéral 17 au quartier médial 18 au niveau du dessus 12 de la tige 3, c'est-à-dire aussi au niveau du dessus 12 de l'élément chaussant 15. L'élément chaussant 15, ainsi conformé, présente l'aspect général d'une mule. En conséquence la chaussure 1 présente elle aussi l'aspect d'une mule. Cette dernière est très confortable, parce qu'elle présente une continuité de matière sous la voute plantaire et de part et d'autre de la voute transversalement. Bien entendu cette continuité est effective au niveau de la première zone intermédiaire 32.It can be observed that the lateral quarter 17 extends forward of the lateral border 28, a permanent securing means 61 connecting the lateral quarter 17 to the internal sole 16 in front of the lateral border 28. It is also observed that the medial quarter 18 s extends forward of the medial border 29, a permanent securing means 62 connecting the medial area 18 to the sole 16 in front of the medial border 29. Finally, it can be seen that a permanent securing means 63 connects the lateral area 17 to the neighborhood medial 18 at the top 12 of the upper 3, that is to say also at the top 12 of the footwear element 15. The footwear element 15, thus shaped, has the general appearance of a mule . As a result, the shoe 1 also has the appearance of a mule. This last one is very comfortable, because it presents a continuity of matter under the plantar vault and on both sides of the vault transversely. Of course, this continuity is effective at the level of the first intermediate zone 32.

Selon la première forme de réalisation, les trois moyens de solidarisation 61, 62, 63 ci-avant évoqués sont des coutures. Ces moyens sont communs et faciles à mettre en oeuvre. Mais il peut être prévu d'autres moyens, tels que des collages, des soudages, ou autre. D'une manière générale, on peut dire que l'un ou plusieurs des moyens de solidarisation 61, 62, 63 sont des coutures.According to the first embodiment, the three securing means 61, 62, 63 mentioned above are seams. These means are common and easy to implement. But it can be provided other means, such as collages, welding, or other. In general, it can be said that one or more of the securing means 61, 62, 63 are seams.

De manière non limitative, chaque couture 61, 62, 63 maintient, l'une par rapport à l'autre, deux subdivisions 16, 17, 18 du premier élément chaussant 15 par aboutage, c'est-à-dire bord contre bord. Plus précisément le bord inférieur avant 41 du quartier latéral 17 aboute le bord latéral 26 du semelage interne 16, le bord inférieur avant 43 du quartier médial 18 aboute le bord médial 27 du semelage interne 16, et le bord supérieur 55 du quartier latéral 17 aboute le bord supérieur 56 du quartier médial 18. Cet agencement est celui qui donne à l'élément chaussant 15, et donc aussi à la tige 3, la meilleure régularité de courbure là où la continuité de matière n'est pas réalisée. Il s'ensuit que l'enveloppement du pied et le confort sont optimisés. Rien n'empêche cependant de prévoir une superposition d'un quartier 17, 18 avec le semelage interne 16, ou des quartiers entre-eux. En effet la continuité de matière, et le confort qui en découle, reste au niveau de la voute plantaire.In a nonlimiting manner, each seam 61, 62, 63 maintains, with respect to the other, two subdivisions 16, 17, 18 of the first footwear 15 by butting, that is to say edge against edge. More specifically, the lower front edge 41 of the lateral portion 17 abuts the lateral edge 26 of the internal sole 16, the lower front edge 43 of the medial quarter 18 abuts the medial edge 27 of the internal sole 16, and the upper edge 55 of the side portion 17 abut the upper edge 56 of the medial quarter 18. This arrangement is the one that gives the footwear element 15, and therefore also to the rod 3, the best regularity of curvature where the material continuity is not achieved. It follows that the wrapping of the foot and the comfort are optimized. Nothing prevents, however, to provide a superposition of a quarter 17, 18 with the internal sole 16, or neighborhoods between them. In fact the continuity of matter, and the comfort that results, remains at the level of the plantar arch.

On remarque que la jonction entre le quartier latéral 17 et le quartier médial 18, au niveau du dessus 12 de la tige 3, est orientée selon la direction longitudinale L. Par voie de conséquence, le moyen de solidarisation 63 des quartiers 17, 18, à savoir ici la couture 63, est orienté selon la direction longitudinale L. Il en est ainsi parce que les bords supérieurs 55, 56 du patron 20 sont orientés selon la direction longitudinale L. Cela facilite la fabrication du patron, et aussi sa mise en forme pour obtenir l'élément chaussant 15.Note that the junction between the lateral quarter 17 and the medial quarter 18, at the top 12 of the rod 3, is oriented in the longitudinal direction L. As a result, the securing means 63 of the quarters 17, 18, namely here the seam 63, is oriented in the longitudinal direction L. It is so because the upper edges 55, 56 of the boss 20 are oriented in the longitudinal direction L. This facilitates the manufacture of the pattern, and also its implementation form to obtain the footwear element 15.

Pour réaliser la chaussure 1, comme on le comprend à l'aide de la figure 6, il est prévu de solidariser l'élément chaussant 15 au semelage externe 2. De manière non limitative, ce dernier 2 comprend une couche d'usure 71, prévue pour contacter le sol, et une couche intermédiaire 72, disposée au final entre la couche d'usure 71 et l'élément chaussant 15. La couche d'usure 71 est constituée d'un ou plusieurs matériaux résistant à l'abrasion, tel que du caoutchouc. La couche intermédiaire 72, quant à elle, est par exemple une couche d'amortissement, constituée d'un ou plusieurs matériaux prévus pour amortir les chocs. De manière non limitative, la couche intermédiaire est ici constituée d'éthyle-vinyle-acétate, désigné sous l'acronyme EVA, ou de tout matériau similaire, tel qu'un polyuréthane, ou autre. Dans le sens de l'épaisseur, le semelage 2 s'étend donc depuis la couche d'usure 71 jusqu'à une face de solidarisation 73, laquelle est délimitée par le dessus de la couche intermédiaire 72. La chaussure 1 est obtenue en solidarisant l'élément chaussant 15 à la face de solidarisation 73, par exemple par collage. On observe que la face 73 présente une forme vallonnée, non plane, pour mieux s'adapter à la tige et à la plante du pied. Cela évite l'emploi d'un semelage interne supplémentaire.To realize the shoe 1, as understood by using the figure 6 , it is intended to secure the footwear element 15 to the outer sole 2. Without limitation, the latter 2 comprises a wear layer 71, provided to contact the ground, and an intermediate layer 72, finally disposed between the layer 71 and the footwear element 15. The wear layer 71 consists of one or more abrasion-resistant materials, such as rubber. The intermediate layer 72, for its part, is for example a damping layer, consisting of one or more materials provided for damping shocks. In a nonlimiting manner, the intermediate layer is here constituted of ethyl-vinyl-acetate, designated by the acronym EVA, or of any similar material, such as a polyurethane, or other. In the direction of the thickness, the sole 2 thus extends from the wear layer 71 to a securing face 73, which is defined by the top of the intermediate layer 72. The shoe 1 is obtained by solidarizing the footwear element 15 to the securing face 73, for example by gluing. It is observed that the face 73 has a hilly shape, not flat, to better adapt to the stem and the sole of the foot. This avoids the use of an additional internal sole.

De manière non limitative, la solidarisation est faite de façon que les moyens de solidarisation permanente 61, 62 des quartiers latéral 17 et médial 18 au semelage interne 16 sont en regard du semelage externe 2. Cela signifie que les moyens de solidarisation permanente 61, 62 sont en regard de la face de solidarisation 73. En conséquence, comme on le voit sur la figure 1, ces moyens 61, 62 sont invisibles extérieurement sur la chaussure 1 finie. On peut dire que le semelage externe 2 couvre les moyens de solidarisation permanente 61, 62. Cela accroît la solidité de la chaussure 1, et lui confère une esthétique plus agréable.In a nonlimiting manner, the fastening is made in such a way that the permanent fastening means 61, 62 of the lateral 17 and medial 18 quarters at the internal sole 16 are opposite the outer soleing 2. This means that the permanent fastening means 61, 62 are next to the fastening face 73. As a result, as can be seen on the figure 1 these means 61, 62 are invisible externally on the finished shoe 1. It can be said that the outer sole 2 covers the permanent securing means 61, 62. This increases the strength of the shoe 1, and gives it a more pleasant aesthetic.

On remarque en complément qu'un galon 74 s'étend à la jonction des quartiers latéral 17 et médial 18 au niveau du dessus 12 de la tige 3. Le galon 74 couvre le moyen de solidarisation 63, c'est-à-dire la couture 63, ce qui là encore accroît la solidité de la chaussure 1, et lui confère une esthétique plus agréable. Il pourrait alternativement être prévu un galon essentiellement ou purement décoratif, qui couvrirait alors partiellement, voire pas du tout, la jonction des quartiers.It should be noted in addition that a strip 74 extends at the junction of the lateral 17 and medial 18 areas at the top 12 of the rod 3. The strip 74 covers the securing means 63, that is to say the 63, which again increases the strength of the shoe 1, and gives it a more pleasant aesthetic. It could alternatively be planned a strip essentially or purely decorative, which would then partially cover, if at all, the junction of neighborhoods.

La chaussure 1 obtenue est à la fois légère et confortable.The shoe 1 obtained is both light and comfortable.

Les autres formes de réalisation vont être présentées ci-après à l'aide des figures 7 à 13. Pour des raisons de commodité, les éléments communs avec la première forme sont désignés par les mêmes références.The other embodiments will be presented below with the help of Figures 7 to 13 . For the sake of convenience, the elements common with the first form are designated by the same references.

Tout d'abord la deuxième forme de réalisation est abordée en regard des figures 7 et 8. On retrouve notamment, pour cette forme, une chaussure 91 qui comprend un semelage externe 92 et une tige 93. La chaussure s'étend selon une direction longitudinale L depuis un talon 94 jusqu'à une pointe 95, et selon une direction transversale w entre un côté latéral 96 et un côté médial 97. La chaussure 91 comprend un élément chaussant 105, avec un semelage interne 106, un quartier latéral 107, et un quartier médial 108. Là encore le semelage interne 106 est disposé entre le quartier latéral 107 et le quartier médial 108, ces trois éléments étant solidarisés par continuité de matière selon un patron 110.First of all, the second embodiment is discussed with regard to Figures 7 and 8 . In this form, for example, there is a shoe 91 that includes an outer sole 92 and a shank 93. The shoe extends in a longitudinal direction L from a heel 94 to a point 95, and in a transverse direction w between a lateral side 96 and a medial side 97. The shoe 91 comprises a footwear 105, with an internal sole 106, a lateral quarter 107, and a medial quarter 108. Here again the inner soleing 106 is disposed between the lateral quarter 107 and the medial quarter 108, these three elements being secured by continuity of material according to a pattern 110.

Le semelage interne 106 s'étend en longueur depuis une extrémité arrière 114 jusqu'à une extrémité avant 115, et en largeur entre une frontière latérale 118 et une frontière médiale 119. Le semelage interne 106 présente une zone arrière 121, une première zone intermédiaire 122, une deuxième zone intermédiaire 123, et une zone avant 124.The internal sizing 106 extends in length from a rear end 114 to a front end 115, and in width between a lateral boundary 118 and a medial boundary 119. The internal seaming 106 has a rear zone 121, a first intermediate zone 122, a second intermediate zone 123, and a front zone 124.

Ce qui est spécifique à la deuxième forme de réalisation de l'invention, c'est que le quartier latéral 107 est relié au semelage interne 106 uniquement par continuité de matière, et que le quartier médial 108 est relié au semelage interne 106 uniquement par continuité de matière. Cela simplifie la fabrication de l'élément chaussant 105. De manière non limitative, le quartier latéral 107, et donc aussi la frontière latérale 118, s'étend au niveau des première 122 et deuxième 123 zones intermédiaires. Dans le même esprit le quartier médial 108, et aussi la frontière médiale 119, s'étend au niveau des première 122 et deuxième 123 zones intermédiaires. Cela revient à dire qu'une continuité de matière latérale 118 s'étend au niveau des première 122 et deuxième 123 zones intermédiaires, et qu'une continuité de matière médiale 119 s'étend au niveau des première 122 et deuxième 123 zones intermédiaires. C'est pourquoi la chaussure 91 enveloppe le pied, transversalement, avec une grande précision et de manière confortable. La continuité de matière rend l'élément chaussant 105 apte à épouser la plante et les parties transversales du pied.What is specific to the second embodiment of the invention is that the lateral quarter 107 is connected to the internal sole 106 only by continuity of material, and that the medial quarter 108 is connected to the internal sole 106 only by continuity of matter. This simplifies the manufacture of the footwear 105. In a nonlimiting manner, the lateral quarter 107, and thus also the lateral border 118, extends at the first 122 and second 123 intermediate zones. In the same spirit the medial quarter 108, and also the medial border 119, extends at the first 122 and second 123 intermediate zones. That is, a lateral material continuity 118 extends at the first 122 and second 123 intermediate zones, and a medial continuity 119 extends at the first 122 and second 123 intermediate zones. This is why the shoe 91 wraps the foot, transversely, with great precision and comfortably. The continuity of material makes the footwear element 105 able to fit the plant and the transverse parts of the foot.

Le quartier latéral 107 comprend par exemple une extension transversale arrière 131 et une extension transversale avant 132 reliées l'une à l'autre par un pont 133, ainsi qu'une branche arrière 134 issue de l'extension transversale arrière 131. Dans le même esprit le quartier médial 108 comprend par exemple une extension transversale arrière 141 et une extension transversale avant 142 reliées l'une à l'autre par un pont 143, ainsi qu'une branche arrière 144 issue de l'extension transversale arrière 141.The lateral quarter 107 comprises for example a rear transverse extension 131 and a transverse extension before 132 connected to each other by a bridge 133, as well as a rear branch 134 resulting from the rear transverse extension 131. mind the medial quarter 108 includes for example a rear transverse extension 141 and an extension transverse front 142 connected to each other by a bridge 143, and a rear branch 144 from the rear transverse extension 141.

Pour donner à l'élément chaussant 105 sa forme en trois dimensions, la chaussure 91 comprend un moyen de solidarisation 151 des extensions transversales arrière 131, 141 l'une à l'autre, un moyen de solidarisation 152 des extensions transversales avant 132, 142 l'une à l'autre , ainsi qu'un moyen de solidarisation 154 des branches arrière 134, 144 l'une à l'autre. Chacun de ces moyens 151, 152, 154 peut être, selon besoin, un moyen de solidarisation permanente ou, alternativement, un moyen de solidarisation amovible. La chaussure 91 obtenue est une sandale.To give the footwear 105 its three-dimensional shape, the shoe 91 comprises a securing means 151 of the rear transverse extensions 131, 141 to one another, a means 152 for securing the transverse extensions before 132, 142 one to the other, and a securing means 154 of the rear branches 134, 144 to one another. Each of these means 151, 152, 154 may be, as required, a permanent securing means or, alternatively, a removable fastening means. The shoe 91 obtained is a sandal.

La troisième forme de réalisation de l'invention est présentée maintenant à l'aide des figures 9 à 11. Parce qu'elle est très proche de la première, la troisième forme de réalisation présente avec celle-ci de nombreux éléments communs. On retrouve donc sur la figure 9 un élément chaussant 175, lequel comprend un semelage interne 16, un quartier latéral 177 et un quartier médial 178. Le semelage interne 16 présente une extrémité arrière 24 et une extrémité avant 25. Le quartier latéral 177 présente un bord inférieur avant 41 et un bord supérieur 55. Le quartier médial 178 présente un bord inférieur avant 43 et un bord supérieur 56. Une frontière latérale 28, entre le semelage interne 16 et le quartier latéral 177, s'étend au niveau de la première zone intermédiaire 32 et de la deuxième zone intermédiaire 33. Une frontière médiale 29, entre le semelage interne 16 et le quartier médial 178, s'étend au niveau de la première zone intermédiaire 32 et de la deuxième zone intermédiaire 33.The third embodiment of the invention is now presented with the help of Figures 9 to 11 . Because it is very close to the first, the third embodiment has with it many common elements. So we find on the figure 9 a footwear element 175, which comprises an internal sole 16, a lateral quarter 177 and a medial quarter 178. The internal sole 16 has a rear end 24 and a front end 25. The side portion 177 has a front lower edge 41 and an edge 55. The medial quarter 178 has a front lower edge 43 and an upper edge 56. A lateral border 28, between the internal sole 16 and the lateral side 177, extends at the level of the first intermediate zone 32 and the second intermediate zone 32. intermediate zone 33. A medial border 29, between the internal sole 16 and the medial quarter 178, extends at the level of the first intermediate zone 32 and the second intermediate zone 33.

Ce qui est spécifique à la troisième forme de réalisation, c'est l'organisation de la partie arrière de la chaussure.What is specific to the third embodiment is the organization of the rear part of the shoe.

Ainsi le quartier latéral 177 présente, de la frontière 28 au bord supérieur 55, un bord inférieur arrière 181, convexe, un bord intermédiaire arrière 182, droit, et un bord d'entrée 183, concave. Dans le même esprit le quartier médial 178 présente, de la frontière 29 au bord supérieur 56, un bord inférieur arrière 191, convexe, un bord intermédiaire arrière 192, droit, et un bord d'entrée 193, concave.Thus the side portion 177 has, from the border 28 to the upper edge 55, a rear lower edge 181, convex, a rear intermediate edge 182, right, and an entrance edge 183, concave. In the same spirit the medial quarter 178 has, from the border 29 to the upper edge 56, a rear lower edge 191, convex, a rear intermediate edge 192, right, and an entrance edge 193, concave.

En conséquence après que l'élément chaussant 175 ait été conformé en trois dimensions, comme c'est le cas sur les figures 10 et 11, le quartier latéral 177 s'étend en arrière de la frontière latérale 28, un moyen de solidarisation permanente 201 reliant le quartier latéral 177 en semelage interne 16 en arrière de la frontière latérale 28, le quartier médial 178 s'étend en arrière de la frontière médiale 29, un moyen de solidarisation permanente 202 reliant le quartier médial 178 au semelage interne 16 en arrière de la frontière médiale 29, et un moyen de solidarisation permanente 203 relie le quartier latéral 177 au quartier médial 178 au niveau de l'extrémité arrière 4 de la chaussure. De manière non limitative, comme on l'a vu pour la première forme de réalisation, les moyens de solidarisation permanente 201, 202, 203 comprennent chacun une couture. Plus précisément, chaque moyen 201, 202, 203 est constitué d'une couture. Il s'agit à nouveau d'utiliser une technique simple, facile à mettre en oeuvre. La chaussure obtenue, non représentée, affiche l'aspect général d'un soulier, lequel est bien sûr muni d'un semelage externe.Consequently, after the footwear element 175 has been shaped in three dimensions, as is the case on the Figures 10 and 11 , the lateral quarter 177 extends behind the lateral border 28, a permanent securing means 201 connecting the lateral quarter 177 in internal sole 16 behind the lateral border 28, the medial quarter 178 extends behind the medial border 29, a permanent securing means 202 connecting the medial quarter 178 to the internal sole 16 behind the medial border 29, and a permanent securing means 203 connects the lateral quarter 177 to the medial quarter 178 at the rear end 4 of the shoe. Without limitation, as has been seen for the first embodiment, the permanent fastening means 201, 202, 203 each comprise a seam. More specifically, each means 201, 202, 203 consists of a seam. It is again a question of using a simple technique, easy to put into artwork. The shoe obtained, not shown, displays the general appearance of a shoe, which is of course provided with an outer sole.

Selon la troisième forme de réalisation, les moyens de solidarisation permanente 201, 202 des quartiers latéral 177 et médial 178 au semelage interne 16 sont en regard du semelage externe 2. Ils 201, 202 sont donc cachés extérieurement quand la chaussure est assemblée, pour une meilleure esthétique.According to the third embodiment, the permanent securing means 201, 202 of the lateral quarters 177 and medial 178 at the inner sole 16 are opposite the outer sole 2. They 201, 202 are thus hidden externally when the shoe is assembled, for a better aesthetics.

La jonction entre le quartier latéral 177 et le quartier médial 178, au niveau de l'extrémité arrière 4, est contenue dans un plan longitudinal perpendiculaire au semelage externe 2. Cela facilite la solidarisation l'un à l'autre des quartiers 177, 178. Il est aussi prévu qu'un galon, non représenté, s'étende à la jonction des quartiers latéral 177 et médial 178 au niveau de l'extrémité arrière 4. L'esthétique de la chaussure n'en est que meilleure.The junction between the lateral quarter 177 and the medial quarter 178, at the rear end 4, is contained in a longitudinal plane perpendicular to the outer sole 2. This facilitates the joining together of the quarters 177, 178 It is also expected that a stripe, not shown, extends to the junction of the lateral quarters 177 and medial 178 at the rear end 4. The aesthetics of the shoe is only better.

La quatrième forme de réalisation est présentée maintenant à l'aide des figures 12 et 13. Cette forme est identique à la troisième, à un détail près. On retrouve donc le patron qui permet l'obtention de l'élément chaussant 175, avec un semelage interne 16 et ses quartiers 177, 178.The fourth embodiment is now presented using the Figures 12 and 13 . This form is identical to the third, to one detail. We thus find the pattern that allows obtaining the footwear element 175, with an internal sole 16 and its quarters 177, 178.

Ce qui est spécifique à la quatrième forme, c'est que le semelage interne 16 présente une découpe allongée 211, et qu'un moyen de solidarisation permanente 212 relie l'un à l'autre deux bords 213, 214 de la découpe. Ici cette dernière 211 est ménagée dans la première zone intermédiaire 32, et orientée selon la direction longitudinale L. La découpe 211 présente une forme de feuille aux extrémités pointues, et est délimitée par les deux bords 213, 214 seulement. Le moyen de solidarisation permanente 212 est une couture. Celle-ci maintient, l'un par rapport à l'autre, les deux bords 213, 214 de la découpe 211 par aboutage. Cette disposition permet de réduire la largeur de l'élément chaussant au niveau de la voute plantaire, voire du talon. En fait le rétrécissement localisé de l'élément chaussant permet l'adaptation de la chaussure à un pied plus étroit. Bien entendu la régularité de surface du semelage interne 16 est préservée, pour un confort optimal du pied.What is specific to the fourth form is that the internal assembly 16 has an elongated cutout 211, and a permanent securing means 212 connects two edges 213, 214 of the cutout to one another. Here the latter 211 is formed in the first intermediate zone 32, and oriented in the longitudinal direction L. The cut 211 has a leaf shape with pointed ends, and is delimited by the two edges 213, 214 only. The permanent securing means 212 is a seam. This maintains, with respect to each other, the two edges 213, 214 of the cut 211 by butting. This arrangement reduces the width of the footwear element at the level of the plantar arch, or even the heel. In fact the localized narrowing of the footwear element allows the adaptation of the shoe to a narrower foot. Of course, the surface regularity of the inner sole 16 is preserved, for optimal comfort of the foot.

La cinquième forme de réalisation est présentée maintenant à l'aide de la figure 14. Parce qu'elle est très proche de la première, la cinquième forme de réalisation présente avec celle-ci de nombreux éléments communs. On retrouve donc une chaussure 221 qui comprend un semelage externe 2, avec une couche d'usure 71 et une couche intermédiaire 72, ainsi qu'un élément chaussant 225, avec un semelage interne 16, un quartier latéral 227, et un quartier médial 228. Comme on l'a vu le semelage externe 2 s'étend en longueur depuis l'extrémité arrière 4 jusqu'à l'extrémité avant 5, et en largeur entre le côté latéral 6 et le côté médial 7. Le semelage interne 16, quant à lui, s'étend en longueur depuis l'extrémité arrière 24 jusqu'à l'extrémité avant 25, et en largeur entre la frontière latérale 28 et la frontière médiale 29.The fifth embodiment is now presented using the figure 14 . Because it is very close to the first, the fifth embodiment has with it many common elements. There is therefore a shoe 221 which comprises an outer sole 2, with a wear layer 71 and an intermediate layer 72, and a footwear 225, with an internal sole 16, a lateral portion 227, and a medial quarter 228 As has been seen, the outer soleing 2 extends in length from the rear end 4 to the front end 5, and in width between the lateral side 6 and the medial side 7. The internal assembly 16, as for it, extends in length from the rear end 24 to the front end 25, and in width between the lateral border 28 and the medial border 29.

Ce qui est spécifique avec la cinquième forme de réalisation, c'est que la chaussure 221 présente l'aspect général d'une tong. Ainsi le quartier latéral 227 présente un bord avant 231, un bord arrière 232 et un bord supérieur 233. Dans le même esprit le quartier médial 228 présente un bord avant 241, un bord arrière 242, et un bord supérieur 243. Chacun des quartiers 227, 228 est issu du semelage interne 16 au niveau de la première zone intermédiaire 32. Les bords supérieurs 233, 243 des quartiers 227, 228 sont solidarisés l'un à l'autre au niveau du dessus 12. Une attache 245 s'étend depuis le dessus 12 jusqu'au semelage interne 16. Cette attache 245 comprend par exemple une bande, réalisée avec du tissu ou tout équivalent, ou encore un lien de structure quelconque. Bien entendu l'attache 245 est prévue de préférence pour s'insérer entre le gros orteil et le deuxième orteil. Ainsi les quartiers 227, 228 et l'attache 245 forment une double bride, caractéristique d'une tong. On remarque en complément que le semelage interne 16 présente un périmètre réduit par rapport à celui du semelage externe 2, et que ce dernier, autour du semelage interne 16, présente un bord périphérique relevé 246 qui entoure la base du pied. Cela assure une meilleure tenue du pied, et s'inscrit dans le sens de continuité de matière entre le semelage interne 16 et les quartiers 227, 228.What is specific with the fifth embodiment is that the shoe 221 has the general appearance of a flip-flop. Thus the lateral quarter 227 has a front edge 231, a rear edge 232 and an upper edge 233. In the same spirit the medial quarter 228 has a front edge 241, a rear edge 242, and an upper edge 243. Each of the 227, 228 is derived from the internal sole 16 at the first intermediate zone 32. The upper edges 233, 243 of the quarters 227, 228 are secured to one another at the top 12. A fastener 245 s' extends from top 12 to internal assembly 16. This fastener 245 comprises for example a strip, made with fabric or any equivalent, or a link of any structure. Of course the fastener 245 is preferably provided to fit between the big toe and the second toe. Thus the quarters 227, 228 and the fastener 245 form a double flange, characteristic of a flip-flop. It is noted in addition that the inner sole 16 has a reduced perimeter compared to that of the outer sole 2, and the latter around the inner sole 16 has a raised peripheral edge 246 which surrounds the base of the foot. This ensures a better hold of the foot, and is consistent with the continuity of matter between the inner sole 16 and 227, 228 quarters.

Dans tous les cas l'invention est réalisée à partir de matériaux et selon des techniques de mise en oeuvre connus de l'homme du métier.In all cases the invention is made from materials and according to processing techniques known to those skilled in the art.

Bien entendu l'invention n'est pas limitée aux formes de réalisation ci-avant décrites, et comprend tous les équivalents techniques pouvant entrer dans la portée des revendications qui vont suivre.Naturally, the invention is not limited to the embodiments described above, and includes all technical equivalents that fall within the scope of the claims that follow.

Par exemple il peut être prévu d'autres formes pour faire un élément chaussant.For example, other forms may be provided for making a footwear item.

La doublure de l'élément chaussant peut s'étendre sur une partie seulement de l'enveloppe.The lining of the footwear element may extend over only a portion of the shell.

Dans tous les cas une chaussure selon l'invention présente une continuité de matière transversale au niveau de la voûte plantaire, c'est-à-dire dans la première zone intermédiaire.In all cases a shoe according to the invention has a continuity of transverse material at the level of the arch, that is to say in the first intermediate zone.
