Description

L'invention concerne un rivet pour chaussure de sport, particulièrement adapté pour la liaison de différentes parties de chaussures de sport et/ou pour la fixation d'accessoires sur des parties de chaussures de sport. Ce rivet est particulièrement adapté aux chaussures de sport rigides comme les chaussures de ski. L'invention concerne aussi un procédé de fabrication d'un tel rivet ainsi qu'un procédé de fabrication d'une chaussure de sport intégrant un tel rivet.The invention relates to a rivet for sports shoes, particularly suitable for connecting different parts of sports shoes and / or for attaching accessories to parts of sports shoes. This rivet is particularly suitable for rigid sports shoes such as ski boots. The invention also relates to a method of manufacturing such a rivet and a method of manufacturing a sports shoe incorporating such a rivet.

La figure 1 illustre une chaussure de ski selon l'état de la technique. Elle comprend principalement deux parties, un collier 1 et une coque 2, reliées par un rivet de type Borchia 3, c'est-à-dire caractérisé par sa taille importante et sa structure en général en aluminium plein. Ce rivet 3 forme un axe de rotation pour une liaison mobile en rotation du collier 1 par rapport à la coque 2. De plus, la chaussure comprend des dispositifs de fermeture et serrage agencés de part et d'autre d'une échancrure centrale permettant de rapprocher les deux parties latérales formant des rabats autour de cette échancrure. Ces dispositifs de fermeture et serrage se composent principalement d'une crémaillère 4 montée mobile en rotation autour d'une fixation par un rivet 5 par exemple sur un premier rabat. Sur le second rabat opposé aux crémaillères 4 sont positionnés des leviers de serrage 6 fixés mobiles en rotation sur une embase sur la chaussure, par un point de fixation non représenté qui peut aussi être un rivet, pour permettre d'actionner un organe de serrage 7 comprenant une tige à son extrémité adaptée pour coopérer avec les dents de la crémaillère 4. Enfin, la chaussure comprend de plus un élément d'étanchéité 8 au niveau de la partie antérieure des rabats de la coque 2, pour éviter que la neige ou l'eau puisse pénétrer dans la chaussure. Un tel dispositif d'étanchéité 8 est aussi fixé sur la coque par au moins un rivet de fixation 9 par l'intermédiaire d'une plaquette de répartition d'effort 9'.The figure 1 illustrates a ski boot according to the state of the art. It mainly comprises two parts, a collar 1 and a shell 2, connected by a type Borchia rivet 3, that is to say characterized by its large size and its structure in general solid aluminum. This rivet 3 forms an axis of rotation for a movable connection in rotation of the collar 1 relative to the shell 2. In addition, the shoe comprises closure and clamping devices arranged on either side of a central notch allowing bring the two lateral parts forming flaps around this notch. These closing and clamping devices consist mainly of a rack 4 mounted to rotate around an attachment by a rivet 5 for example on a first flap. On the second flap opposite the racks 4 are positioned clamping levers 6 fixed rotatably on a base on the boot, by a not shown fastening point which can also be a rivet, to allow to actuate a clamping member 7 comprising a rod at its end adapted to cooperate with the teeth of the rack 4. Finally, the boot further comprises a sealing member 8 at the front portion of the flaps of the shell 2, to prevent the snow or the water can penetrate the shoe. Such a sealing device 8 is also fixed on the shell by at least one fastening rivet 9 by means of a force distribution plate 9 '.

Ces différents éléments d'une telle chaussure de sport se présentent dans un matériau très rigide : les accessoires sont principalement en métal et les parties de chaussure sont dans un plastique rigide, par exemple un polyuréthane de dureté 55 shd. Il existe donc un besoin spécifique de moyens de fixation pour relier ces éléments rigides entre eux et former la chaussure finale. Dans l'état de la technique, des rivets de fixation 3, 5, 9 sont utilisés : ils présentent une tête qui reste visible sur la surface extérieure de la chaussure de ski, ce qui n'est pas très esthétique. Ces rivets peuvent soit être des rivets standard, pour lesquels le choix reste limité aux formes, formats, et esthétiques standardisés, ou des rivets spécifiques, pour lesquels une forme particulière peut être obtenue mais à un coût élevé et souvent dissuasif. Ces rivets spécifiques esthétiques, souvent appelés Borchia dans le domaine de la chaussure de sport, ont en général une forme complexe avec une tête arrondie et sont fabriqués à l'unité par moulage. D'une manière générale, les procédés de fabrication existants de ces rivets possèdent l'inconvénient d'une grande complexité et d'un coût élevé, qui se répercute sur le coût final de la chaussure de sport. Un rivet selon le préambule de la revendication 1 est connu de FR 2 109 767 .These different elements of such a sports shoe are in a very rigid material: the accessories are mainly metal and the shoe parts are in a rigid plastic, for example a polyurethane hardness 55 shd. There is therefore a specific need for fastening means for connecting these rigid elements together and forming the final shoe. In the state of the art, fixing rivets 3, 5, 9 are used: they have a head which remains visible on the outer surface of the ski boot, which is not very aesthetic. These rivets can either be standard rivets, for which the choice remains limited to standardized shapes, formats, and aesthetics, or specific rivets, for which a particular shape can be obtained but at a high cost and often a deterrent. These specific aesthetic rivets, often called Borchia in the field of sports shoes, usually have a complex shape with a rounded head and are manufactured individually by molding. In general, the existing manufacturing processes of these rivets have the disadvantage of a great complexity and a high cost, which has repercussions on the final cost of the sports shoe. A rivet according to the preamble of claim 1 is known from FR 2,109,767 .

Un premier objet de la présente invention consiste en un rivet pour chaussure de sport combinant un aspect esthétiquement attractif pour un coût minimum.A first object of the present invention is a rivet for a sports shoe combining an aesthetically attractive appearance for a minimum cost.

Un second objet de la présente invention consiste en un procédé de fabrication économique d'un rivet pour chaussure de sport et d'une chaussure de sport correspondante intégrant un tel rivet.A second object of the present invention is a method for the economical manufacture of a rivet for sports shoes and a corresponding sports shoe incorporating such a rivet.

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

These objects, features and advantages of the present invention will be set forth in detail in the following description of a particular embodiment made in a non-limiting manner in relation to the appended figures among which:
  • The figure 1 is a perspective view of a ski boot according to the state of the art;
  • the figure 2 is a side sectional view of a fastening device according to an embodiment of the invention;

L'invention va être illustrée dans le cadre d'une chaussure de ski mais pourrait être implémentée sur toute chaussure de sport nécessitant la liaison de plusieurs parties et/ou accessoires, et particulièrement celles nécessitant une grande résistance, composées d'éléments rigides et devant résister à des efforts importants lors de leur utilisation.The invention will be illustrated in the context of a ski boot but could be implemented on any sports shoe requiring the connection of several parts and / or accessories, and particularly those requiring high strength, composed of rigid elements and in front resist significant efforts when using them.

Selon le concept de l'invention, le rivet se compose d'au moins deux parties distinctes emboîtables, fabriquées séparément. La première partie, dite pied, comprend une tige destinée à traverser la paroi de la chaussure de sport lors de sa fixation sur la chaussure et un moyen de liaison avec la seconde partie, dite tête, qui est destinée à reposer de manière visible sur la surface de la chaussure, remplissant ainsi une fonction esthétique. En variante, cette tête peut remplir une fonction supplémentaire, comme celle d'un accessoire de chaussure.According to the concept of the invention, the rivet is composed of at least two separate interlocking parts, manufactured separately. The first part, said foot, comprises a rod intended to pass through the wall of the sports shoe when it is fastened to the boot and a means of connection with the second part, called the head, which is intended to rest visibly on the surface of the shoe, thus fulfilling an aesthetic function. Alternatively, this head can perform an additional function, such as that of a shoe accessory.

Selon le mode d'exécution représenté sur les figures 2 et 3, le rivet 10 se compose d'un pied 11 et d'une tête 12. Le pied 11 comprend une tige cylindrique 13 dont une première extrémité comprend un élément plat 14 en forme de disque et une seconde extrémité 18 est destinée à se déformer lors d'une fixation par rivetage sur une chaussure. La tête 12 métallique comprend une surface supérieure 15 destinée à être visible sur la surface de la chaussure, qui remplit une première fonction esthétique. La tête 12 est de plus destinée à remplir une fonction semblable à celle de la plaquette 9' de l'état de la technique associée à l'élément d'étanchéité 8 présenté sur la figure 1. Comme cette tête 12 présente une surface sans ouverture, elle offre une étanchéité supérieure à la solution de l'état de la technique pour laquelle de l'eau peut s'infiltrer au niveau du rivet 9. Enfin, au niveau de sa surface inférieure 19, la tête 12 comprend deux glissières parallèles 17 adaptées au logement de l'élément plat 14 du pied 11. Cela permet un emboîtement provisoire amovible de ces deux parties 11, 12 pour former le rivet 10.According to the embodiment shown on the Figures 2 and 3 , the rivet 10 consists of a foot 11 and a head 12. The foot 11 comprises a cylindrical rod 13 whose one end comprises a flat element 14 in the form of a disk and a second end 18 is intended to deform when a fastening by riveting on a shoe. The metal head 12 comprises an upper surface 15 intended to be visible on the surface of the shoe, which fulfills a first aesthetic function. The head 12 is also intended to perform a function similar to that of the plate 9 'of the state of the art associated with the sealing element 8 presented on the figure 1 . As this head 12 has a surface without opening, it offers a superior seal to the solution of the state of the art for which water can infiltrate at the rivet 9. Finally, at its lower surface 19 , the head 12 comprises two parallel slides 17 adapted to the housing of the flat element 14 of the foot 11. This allows a removable temporary interlocking of these two parts 11, 12 to form the rivet 10.

Après rivetage de ce rivet 10 sur une chaussure de sport, l'extrémité 18 de la tige 13 du pied 11 est déformée au niveau de la surface intérieure de la paroi de la chaussure. Cette paroi de la chaussure se trouve finalement traversée par la tige 13 et emprisonnée entre cette extrémité déformée 18 et la surface inférieure 19 de la tête 12. De plus, l'autre extrémité 14 du pied 11 est logée dans les glissières 17 sous la surface 19 de la tête 12, de sorte que l'ensemble du pied 11 du rivet 10 reste caché sous la tête 12. Seule la surface supérieure 15 de la tête 12 apparaît à la surface de la chaussure, ce qui permet d'atteindre une esthétique très attrayante, puisque comme cela est décrit par la suite, elle peut avoir facilement n'importe quelle forme par un procédé de fabrication très simple. L'invention porte aussi sur le procédé de fabrication d'un rivet 10 tel que décrit précédemment. Un tel procédé comprend une première étape de fabrication du pied 11. Comme il est destiné à être caché et peu ou pas visible, son esthétique a peu d'importance et il est possible de choisir une forme permettant une fabrication simple et économique, assurant toutefois la fonction mécanique de fixation de manière performante. Notamment, son moyen de liaison avec la tête 12 peut présenter une forme la plus simple possible, comme un élément plat 14, tel que représenté sur les figures 2 et 3, monté sur une simple tige cylindrique 13. Toute opération d'usinage est ainsi très simple lors de la fabrication du pied 11 qui est économique et entraîne peu de perte de matière.After riveting this rivet 10 on a sports shoe, the end 18 of the shank 13 of the foot 11 is deformed at the inner surface of the wall of the shoe. This wall of the boot is finally traversed by the rod 13 and trapped between this deformed end 18 and the lower surface 19 of the head 12. In addition, the other end 14 of the foot 11 is housed in the slides 17 below the surface 19 of the head 12, so that the entire foot 11 of the rivet 10 remains hidden under the head 12. Only the upper surface 15 of the head 12 appears on the surface of the shoe, which achieves an aesthetic very attractive, since as described later, it can easily have any shape by a very simple manufacturing process. The invention also relates to the method of manufacturing a rivet 10 as described above. Such a method comprises a first step of manufacturing the foot 11. As it is intended to be hidden and little or not visible, its aesthetic is of little importance and it is possible to choose a form allowing a simple and economical manufacturing, however ensuring the mechanical function of fixation in a powerful way. In particular, its connecting means with the head 12 may have a simplest possible shape, such as a flat element 14, as shown in FIGS. Figures 2 and 3 mounted on a single cylindrical rod 13. Any machining operation is thus very simple during the manufacture of the foot 11 which is economical and causes little loss of material.

Ensuite, le procédé de fabrication comprend une seconde étape de fabrication de la tête 12. Cette tête étant distincte du reste du rivet, elle présente aussi globalement une forme simplifiée et peut aussi être facilement fabriquée. Ainsi, une première sous-étape peut consister à fabriquer par extrusion une longue barre métallique, comprenant de longues glissières parallèles, de forme telle qu'après découpage transversal à la direction de l'extrusion, on obtienne un élément correspondant à la tête 12 représentée sur les figures 2 et 3. Avec un tel procédé, les glissières 17 de la tête 12 s'étendent sur toute la surface inférieure 19 de la tête 12 dans la direction de l'extrusion et ne nécessitent pas d'usinage ultérieur, ce qui est une des raisons permettant d'atteindre un bas coût. La tête 12 présente une largeur constante. Il est ensuite possible éventuellement de travailler simplement la forme de la tête 12 par quelques sous-étapes de découpe ou fraisage supplémentaires pour obtenir toute forme prédéfinie.Then, the manufacturing method comprises a second step of manufacturing the head 12. This head being distinct from the rest of the rivet, it also has a generally simplified shape and can also be easily manufactured. Thus, a first sub-step may consist in producing by extrusion a long metal bar, comprising long parallel rails, of such shape that after cutting transverse to the direction of the extrusion, one obtains an element corresponding to the head 12 shown on the Figures 2 and 3 . With such a method, the slides 17 of the head 12 extend over the entire lower surface 19 of the head 12 in the direction of the extrusion and do not require subsequent machining, which is one of the reasons for achieve a low cost. The head 12 has a constant width. It is then possible to possibly simply work the shape of the head 12 by some additional sub-steps of cutting or milling to obtain any predefined shape.

Plus généralement, le procédé de fabrication en deux étapes distinctes de deux parties distinctes du rivet permet la fabrication de deux parties plus simples, ce qui autorise des procédés de fabrication plus économiques. Notamment, le procédé d'extrusion est plus facile à implémenter, pour former tout ou partie d'au moins une des parties du rivet, et les éventuelles étapes de découpage, usinage, sont plus simples et engendrent moins de perte de matériau.More generally, the manufacturing process in two distinct stages of two distinct parts of the rivet allows the manufacture of two parts more simple, which allows more economical manufacturing processes. In particular, the extrusion process is easier to implement, to form all or part of at least one of the parts of the rivet, and the possible steps of cutting, machining, are simpler and generate less material loss.

Le procédé de fabrication comprend enfin une troisième étape d'emboîtement amovible des deux parties 11, 12 du rivet 10, de préférence mécanique. Il n'y a pas obligation de réaliser une fixation inséparable de ces deux éléments à ce stade puisque leur réelle fixation ne devient nécessaire que lors de la fixation du rivet sur la chaussure. Ainsi, il est prévu deux moyens de liaison correspondant sur respectivement le pied 11 et la tête 12 du rivet 10, de sorte que ces éléments puissent être emboîtés puis fixés ultérieurement. Ainsi, d'autres variantes peuvent être imaginées, le pied 11 et la tête 12 pourraient être assemblés par d'autres moyens mécaniques, les glissières 17 pouvant être des bras quelconques et l'élément plat 14 pouvant adopter d'autres formes. Selon une autre variante, ces deux parties 11, 12 pourraient être assemblées par d'autres moyens à base de soudure, collage...The manufacturing method finally comprises a third step of detachable interlocking of the two parts 11, 12 of the rivet 10, preferably mechanical. There is no obligation to achieve an inseparable attachment of these two elements at this stage since their actual fixation becomes necessary only when fixing the rivet on the shoe. Thus, there are two corresponding connecting means on respectively the foot 11 and the head 12 of the rivet 10, so that these elements can be nested and then fixed later. Thus, other variants can be imagined, the foot 11 and the head 12 could be assembled by other mechanical means, the slides 17 can be any arm and the flat element 14 can adopt other forms. According to another variant, these two parts 11, 12 could be assembled by other means based on welding, gluing ...

Selon le mode d'exécution avantageux illustré sur les figures 2 et 3, cet assemblage est mécanique et sa fixation durable et définitive est obtenue simultanément à la fixation du rivet 10 sur la chaussure, lors d'une opération de rivetage qui induit dans le même temps la fixation du rivet 10 sur la paroi de la chaussure et la fixation définitive des deux parties 11, 12 du rivet entre elles.According to the advantageous embodiment illustrated on the Figures 2 and 3 this assembly is mechanical and its durable and final fixing is obtained simultaneously with the fixing of the rivet 10 on the shoe, during a riveting operation which at the same time induces the fastening of the rivet 10 on the wall of the shoe and the final fixing of the two parts 11, 12 of the rivet between them.

L'invention est particulièrement adaptée pour la fabrication de rivets de type Borchia, en matériau métallique plein, en aluminium par exemple. Naturellement, ce concept peut être implémenté sur un rivet dans un autre matériau comme un plastique rigide. De plus, le procédé de fabrication est adapté à toute forme de rivet, cette forme dépendant de l'emplacement final qu'il occupe sur la chaussure et des éventuelles fonctions mécaniques qu'il peut remplir, en plus de sa fonction esthétique.The invention is particularly suitable for the manufacture of rivets Borchia type, solid metal material, aluminum for example. Naturally, this concept can be implemented on a rivet in another material like a rigid plastic. In addition, the manufacturing method is adapted to any form of rivet, this shape depending on the final location it occupies on the shoe and any mechanical functions it can perform, in addition to its aesthetic function.

Comme cela ressort du mode d'exécution décrit ci-dessus, ce procédé de fabrication permet donc aussi la fabrication d'un accessoire pour chaussure de sport, en utilisant comme tête 12 un élément qui comprend sur sa surface supérieure 15 des moyens pour remplir la fonction de l'accessoire, comme par exemple des dents de crémaillère d'un dispositif de fermeture et serrage ou une forme formant étanchéité sur une surface de la chaussure. Ainsi, l'invention peut aussi être implémentée pour former des accessoires d'étanchéité ou des accessoires de fermeture et serrage de chaussure de sport. Cette technique s'applique donc par exemple aux crémaillères et dentières, dont les dents peuvent être former par l'étape d'extrusion de fabrication de la tête 12, simultanément à la formation des glissières 17. Elle s'adapte facilement à tout accessoire métallique ou plastique pour chaussures de sport. Dans un tel mode d'exécution, le rivet 10 est donc lui-même aussi un accessoire pour chaussure de sport puisqu'il y a en réalité fusion entre l'accessoire et son moyen de liaison sur la chaussure, qui sont distincts dans l'état de la technique, voire obtenus par des procédés excessivement coûteux à base de moulage ou usinage complexe.As is apparent from the embodiment described above, this manufacturing method therefore also allows the manufacture of an accessory for sports shoes, using as head 12 an element which comprises on its upper surface 15 means for filling the function of the accessory, such as, for example, rack and pinion teeth of a closing and clamping device or a form forming a seal on a surface of the boot. Thus, the invention can also be implemented to form sealing accessories or accessories for closing and tightening sports shoes. This technique therefore applies for example to racks and dentures, whose teeth can be formed by the extrusion manufacturing step of the head 12, simultaneously with the formation of the slides 17. It easily adapts to any metal accessory or plastic for sports shoes. In such an embodiment, the rivet 10 is itself also an accessory for sports shoes since there is actually a fusion between the accessory and its binding means on the shoe, which are distinct in the state of the art, or even obtained by excessively expensive processes based on molding or complex machining.

En variante, ce procédé de fabrication permet la réalisation d'un rivet permettant de fixer deux parties de chaussure entre elles, comme la coque et le collier, à la manière du rivet 3 représenté sur la figure 1. Dans ce cas, la tête 12 peut présenter une face extérieure 15 plus élaborée que celle simplement arrondie de l'état de la technique. La surface inférieure 15 de la tête 12 vient en appui sur la surface de la paroi d'une première partie de la chaussure de sport alors que l'extrémité déformée 18 de la tige 13 vient au niveau de la surface intérieure de la paroi de la seconde partie de la chaussure de sport. Ainsi, les deux parois sont traversées par la tige 13 du rivet 10 et bloquées sur leurs deux faces qui ne sont pas en vis-à-vis d'une part par la tête 12 et d'autre part par l'extrémité 18 déformée de la tige 13.Alternatively, this manufacturing method allows the realization of a rivet for attaching two shoe parts together, such as the shell and the collar, in the manner of the rivet 3 shown on the figure 1 . In this case, the head 12 may have an outer face 15 more elaborate than simply rounded of the state of the art. The lower surface 15 of the head 12 bears on the surface of the wall of a first part of the sports shoe while the deformed end 18 of the rod 13 comes at the inner surface of the wall of the second part of the sports shoe. Thus, the two walls are crossed by the rod 13 of the rivet 10 and locked on their two faces which are not vis-a-vis on the one hand by the head 12 and secondly by the distorted end 18 of the stem 13.

L'invention porte aussi sur un procédé de fabrication d'une chaussure de sport intégrant l'utilisation d'au moins un rivet 10 tel que décrit précédemment. Dans un tel cas, le rivet 10 peut servir à fixer deux parties de la chaussure entre elles et/ou à fixer un accessoire sur la surface de la chaussure, comme cela a été décrit précédemment. Le procédé de fabrication de la chaussure comprend alors une étape de liaison du rivet 10 avec la chaussure, dite rivetage, qui peut consister en une pression simultanée sur la surface supérieure 15 de la tête 12 du rivet 10 et sur l'extrémité opposée 18 de la tige 13 du pied 11 du rivet 10. En remarque, afin de supporter au mieux cette pression, la face inférieure 19 de la tête 12 comprend une surface plane 20 entre les glissières 17 en vis-à-vis de l'élément plat 14 afin de favoriser une bonne résistance de l'ensemble lors de l'opération de rivetage. En variante, ces deux surfaces en vis-à-vis des éléments de liaison de respectivement le pied 11 et la tête 12 peuvent présenter toutes formes complémentaires permettant de garantir un bon transfert des efforts lors de l'opération de rivetage. Cette opération permet non seulement le maintien de l'ensemble du rivet sur la chaussure de sport et éventuellement le maintien entre elles de deux parties distinctes de la chaussure, mais aussi la fixation durable et irréversible du pied 11 et de la tête 12 du rivet 10 entre eux. Ainsi, cette opération de rivetage assure simultanément la liaison irréversible d'au moins trois éléments : la chaussure de sport, le pied 11 et la tête 12 du rivet 10. Pour cela, il peut y avoir une modification physique des moyens de liaison des deux éléments 11, 12 lors du rivetage, rendant définitive leur coopération. En variante, la forme de la paroi supérieure de la chaussure peut présenter un logement recevant au moins partiellement la tête 12 pour participer à son maintien efficace sur la surface de la chaussure de sport en complément de son emboîtement sur le pied 11 du rivet 10.The invention also relates to a method of manufacturing a sports shoe incorporating the use of at least one rivet 10 as described above. In such a case, the rivet 10 can be used to attach two parts of the shoe together and / or to fix an accessory on the surface of the shoe, as described above. The method of manufacturing the shoe then comprises a step of binding the rivet 10 to the shoe, said riveting, which may consist of a simultaneous pressure on the upper surface 15 of the head 12 of the rivet 10 and on the opposite end 18 of the stem 13 of the foot 11 of the rivet 10. As a reminder, in order to better withstand this pressure, the lower face 19 of the head 12 comprises a flat surface 20 between the slides 17 vis-à-vis the flat element 14 to promote good strength of the assembly during the riveting operation. Alternatively, these two surfaces vis-à-vis the connecting elements of the foot 11 and the head 12 respectively may have any complementary shapes to ensure a good transfer of forces during the riveting operation. This operation allows not only the maintenance of the entire rivet on the sports shoe and possibly the maintenance between them of two separate parts of the shoe, but also the durable and irreversible fixation of the foot 11 and the head 12 of the rivet 10 between them. Thus, this riveting operation simultaneously ensures the irreversible connection of at least three elements: the sports shoe, the foot 11 and the head 12 of the rivet 10. For this, there may be a physical modification of the connecting means of the two items 11, 12 during riveting, making their cooperation definitive. Alternatively, the shape of the upper wall of the boot may have a housing at least partially receiving the head 12 to participate in its effective maintenance on the surface of the sports shoe in addition to its interlocking on the foot 11 of the rivet 10.

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

  • elle permet de réduire le coût des opérations de fixation nécessaires sur les chaussures de sport ;
  • elle est adaptée à toute chaussure de sport et pour tout type de fixation sur ses parois, que ce soit pour fixer différentes parties de la chaussure entre elles ou pour fixer un accessoire sur la chaussure ;
  • elle permet d'obtenir une esthétique améliorée des chaussures de sport puisque le dispositif de fixation offre une surface visible continue à la surface de la chaussure. Dans l'état de la technique, la tête arrondie du rivet était toujours visible.
Finally, this solution achieves the desired objects and therefore has the following advantages:
  • it reduces the cost of necessary fastening operations on sports shoes;
  • it is suitable for any sports shoe and for any type of attachment on its walls, either to fix different parts of the shoe between them or to fix an accessory on the shoe;
  • it allows to obtain an improved aesthetics of sports shoes since the fastening device provides a continuous visible surface on the surface of the shoe. In the state of the art, the rounded head of the rivet was always visible.
