Description

La présente invention concerne une chaussure de sport, notamment une chaussure de sport de glisse, ou autre sport nécessitant la transmission d'efforts spécifiques et comportant dans sa fabrication au moins une étape de moulage d'au moins l'un de ses éléments. Par sport de glisse, on entend notamment le ski alpin, le ski nordique ou ski de fond, le snowboard, le ski de randonnée ainsi que le patin à glace et à roulettes. Il est largement connu de fabriquer une chaussure de sport par moulage de matière plastique de l'ensemble de ses composants. En général, de telles chaussures sont constituées d'un nombre limité de pièces, seules les pièces appelées à se déplacer les unes par rapport aux autres sont réalisées distinctes les unes des autres. Ce procédé, qui a été très utilisé entre autre pour la fabrication de chaussure de ski alpin et de patins à roulette, est un procédé très coûteux, car il faut réaliser des moules, et peu modulable, car la rigidité de la chaussure reste identique en tout point de celle-ci.The present invention relates to a sports shoe, in particular a sliding sports shoe, or other sport requiring the transmission of specific efforts and comprising in its manufacture at least one molding step of at least one of its elements. By sliding sport we mean in particular Alpine skiing, Nordic skiing or cross-country skiing, snowboarding, ski touring as well as ice skating and roller skating. he is widely known to manufacture a sports shoe by plastic molding of all of its components. In general, such shoes consist of a number limited parts, only the parts called to move the relative to each other are made distinct from each other others. This process, which has been widely used among other things for the manufacture of alpine ski boots and skates in roulette, is a very expensive process, because you have to make molds, and not very flexible, because the rigidity of the shoe remains identical at all points of it.

Pour réaliser une chaussure dont la rigidité n'est pas identique en tout point de celle-ci, on a d'abord pensé à faire varier l'épaisseur de la coque. Cependant, avec ce procédé, il faut, pour obtenir un gradient de rigidité satisfaisant, utiliser un matériau relativement peu rigide et le mouler en surépaisseur aux endroits où on cherche la rigidité maximum.To make a shoe whose stiffness is not identical at all points of it, we first thought of making vary the thickness of the shell. However, with this process, it to obtain a satisfactory stiffness gradient, use a relatively stiff material and mold it into extra thickness in places where maximum stiffness is sought.

A cause de ces surépaisseurs, les chaussures obtenues par ce procédé se révèlent lourdes à l'usage. Une autre solution consiste à faire un moulage bi-matière, mais cette technique reste chère et compliquée. De plus, les deux matières qui sont alors moulées simultanément doivent avoir des propriétés chimiques et physiques relativement proches, ce qui réduit le gradient de rigidité possible.Because of these extra thicknesses, the shoes obtained by this process turns out to be cumbersome in use. Another solution is to make a bi-material molding, but this technique remains expensive and complicated. In addition, the two materials which are then molded simultaneously must have properties relatively close chemical and physical properties, reducing the stiffness gradient possible.

Dans le ski nordique, ou ski de fond, l'exigence de déroulement du pied, en technique classique, et la moindre transmission d'effort font que les chaussures sont en général plus souples et qu'on utilise principalement des techniques traditionnelles dans leur fabrication, c'est-à-dire l'assemblage par collage et par couture. Cependant, ceci n'est plus vrai pour les chaussures destinées à la pratique du pas de patineur (skating) pour lesquelles un déroulement du pied du type effectué en classique n'est plus nécessaire. Ainsi, pour qu'une chaussure de ski de fond soit performante, il faut que certains de ses éléments soient rigides, notamment le contrefort talon. Il se pose alors le problème de l'intégration d'un élément rigide au sein d'une structure souple.In Nordic skiing, or cross-country skiing, the requirement of unfolding of the foot, in classical technique, and the least force transmission means that shoes are generally more flexible and that we mainly use techniques traditional in their manufacture, that is to say assembly by gluing and sewing. However, this is not more true for shoes intended for the practice of the step of skating skaters for whom an unrolling of the foot type performed in classic is no longer necessary. So, for that a cross-country ski boot is efficient, it is necessary that some of its elements are rigid, in particular the heel counter. The problem of integration then arises of a rigid element within a flexible structure.

Dans la fabrication de chaussures pour patins à roulettes, deux types de construction sont actuellement utilisées : la construction rigide et la construction souple. La construction rigide est dérivée de la construction des chaussures de ski alpin : un chausson souple est maintenu dans une coque rigide.In the manufacture of shoes for roller skates, two types of construction are currently used: rigid construction and flexible construction. Construction rigid is derived from the construction of ski boots Alpine: a soft bootie is held in a rigid shell.

Avec une telle construction, chaque renouvellement d'une gamme de patin nécessite l'élaboration de nombreux nouveaux moules et ce, même si l'évolution n'est qu'esthétique.With such a construction, each renewal of a skate range requires the development of many new molds, even if the evolution is only aesthetic.

La construction souple est elle dérivée de la construction de chaussure de ski de fond.Flexible construction is it derived from construction cross-country ski boot.

Avec une telle construction, il est très difficile d'envisager une gamme complète de patin, c'est-à-dire des modèles débutants jusqu'aux modèles confirmés, tout en gardant le maximum d'éléments communs.With such a construction, it is very difficult consider a full range of skates, i.e. beginners to confirmed models, while keeping the maximum of common elements.

Ces deux constructions ont en commun de rendre très onéreuse toute évolution d'une gamme de patin.These two constructions have in common to make very expensive any evolution of a skate range.

La présente invention a pour objet de remédier aux inconvénients précités. Il s'agit en l'occurrence de prévoir une chaussure pour la pratique de sport notamment pour la pratique du ski ou du patin, dont la rigidité n'est pas constante en tout point de celle-ci et dont la structure facilite les évolutions de gamme.The object of the present invention is to remedy the aforementioned drawbacks. This is to provide a shoe for sports practice, particularly for the skiing or skating, the rigidity of which is not constant at every point of it and whose structure facilitates range upgrades.

La chaussure selon l'invention comprend une semelle rigide, une tige extérieure fixée sur cette semelle et un chausson amovible, ou non. La tige extérieure comprend une première portion rigide et non flexible. Cette première portion est fixée sur la semelle ou fait partie intégrante de celle-ci, elle comprend au moins un contrefort talon. La tige extérieure comprend également une deuxième portion à la fois rigide et flexible, fixée sur la première portion et/ou sur la semelle. La tige extérieure comprend en outre une troisième portion, souple, et fixée sur la deuxième portion. The shoe according to the invention comprises a rigid sole, an outer upper attached to this sole and a liner removable or not. The outer rod includes a first rigid and non-flexible portion. This first portion is fixed on the sole or is an integral part thereof, it includes at least one heel counter. The outer rod also includes a second portion which is both rigid and flexible, fixed on the first portion and / or on the sole. The outer rod further comprises a third portion, flexible, and fixed on the second portion.

La disposition des trois portions de tige extérieure les unes par rapport aux autres est telle que, mis à part les zones nécessaires à leur fixation, celles-ci ne se superposent pas, ce qui permet un réel gradient de rigidité de la première portion la plus rigide à la troisième portion souple.The arrangement of the three portions of the outer rod relative to each other is such that, apart from the areas necessary for their fixing, these do not overlap, which allows a real stiffness gradient from the first most rigid portion to the third flexible portion.

De préférence, la deuxième portion comprend une claque à l'avant de la chaussure et un collier au niveau de la cheville, la claque pouvant être fixée par tout moyen de fixation, permanent ou non permanent sur la première portion et / ou sur la semelle. De préférence les moyens de fixation utilisés sont des rivets ou des vis. Dans le cas où ces moyens sont des vis, ils permettent un démontage puis un remontage de la claque sur la première portion et / ou la semelle.Preferably, the second portion comprises a slap to the front of the shoe and a collar at the ankle, the slap being able to be fixed by any fixing means, permanent or non-permanent on the first portion and / or on the sole. Preferably the fixing means used are rivets or screws. In the case where these means are screws, they allow disassembly and reassembly of the slap on the first portion and / or the sole.

La troisième portion comprend une ou plusieurs parties essentiellement fixées sur la deuxième portion par tout moyen de fixation. De préférence la troisième portion est fixée à la deuxième par des moyens de fixation démontables ou non démontables et adaptés aux matériaux souples tels que le collage ou la couture.The third portion includes one or more parts basically attached to the second portion by any means of fixation. Preferably the third portion is attached to the second by removable means or not removable and suitable for flexible materials such as collage or sewing.

La différence de rigidité et de flexibilité entre la première portion et la troisième est importante.The difference in rigidity and flexibility between the first portion and the third is important.

La deuxième portion tout en ayant une rigidité et une flexibilité comprise entre celle de la première et de la troisième peut prendre plusieurs valeurs de rigidité et de flexibilité. On peut donc, en gardant de nombreux éléments communs concevoir une gamme de chaussures comprenant des chaussures à maintien ferme du pied, des chaussures à maintien souple et tous les maintiens intermédiaires. On peut notamment garder la première portion, rigide, commune à l'ensemble des modèles de la gamme en ne changeant que les deuxième et troisième portions et donc diminuer sensiblement les frais de fabrication des moules nécessaires.The second portion while having rigidity and flexibility between that of the first and the third can take multiple values of stiffness and flexibility. We can therefore, by keeping many elements common design a range of shoes including firm footwear, supportive footwear flexible and all intermediate supports. We can in particular keep the first portion, rigid, common to all models of the range by changing only the second and third portions and therefore significantly reduce the costs of manufacture of the necessary molds.

La troisième portion occupe une part importante de la surface de la tige située sur le dessus du pied. Le changement des premières et deuxièmes portions permet de changer l'aspect extérieur de la chaussure. D'autre part, cette pièce peut être moulée à plat, c'est-à-dire sans lui donner la forme qu'elle prendra une fois montée. On peut également obtenir cette troisième portion par découpage à partir de grandes feuilles de matière plastique ou de tissus.The third portion occupies a significant part of the upper surface located on the top of the foot. Change first and second portions to change the appearance outside of the shoe. On the other hand, this piece can be molded flat, that is to say without giving it the shape it will take once climb. We can also get this third portion by cutting from large sheets of plastic or fabric.

Les moyens de serrage de la chaussure sont disposés sur l'une des trois portions. De préférence, ceux-ci comprennent un système à lacet disposé sur la troisième et / ou la deuxième portion permettant l'ajustage du volume de la chaussure au pied de l'utilisateur. Ils comprennent également un système à sangle fixé directement ou indirectement sur le collier et assurant le serrage du bas de la jambe de l'utilisateur. Ils peuvent également comprendre un système à sangle fixé sur le contrefort ou sur la claque et assurant le maintien du talon au fond de la chaussure.The shoe tightening means are arranged on one of the three servings. Preferably, these include a lace system on the third and / or second portion allowing the volume of the shoe to be adjusted to the foot of the user. They also include a strap system fixed directly or indirectly on the collar and ensuring tightening of the user's lower leg. They can also include a strap system attached to the buttress or on the slap and ensuring the maintenance of the heel at the bottom of the shoe.

Un des avantages de l'invention consiste en l'optimisation du compromis entre d'une part, le maintien du pied, et d'autre part, son confort. Dans les zones où le maintien est nécessaire, comme, par exemple, dans la zone talon la tige extérieure est équivalente à une tige rigide de type coque. En revanche, dans les zones où s'effectue un ajustement de la tige au pied de l'utilisateur, c'est-à-dire entre autre, sur le dessus du pied et où le confort est souhaitable, on bénéficie des avantages d'une tige extérieure souple.One of the advantages of the invention consists in the optimization of the compromise between on the one hand, the maintenance of the foot, and on the other apart, its comfort. In areas where maintenance is necessary, like, for example, in the heel area the upper exterior is equivalent to a rigid shell type rod. In however, in areas where the stem is adjusted at the foot of the user, that is to say among other things, on the above the foot and where comfort is desirable, we benefit advantages of a flexible outer rod.

La construction d'une chaussure de sport selon l'invention offre donc à moindre coût, une très grande variété de réalisation : des chaussures ayant de nombreuses pièces communes où utilisant les mêmes moules mais ayant un design qui leur est propre, des chaussures dont les pièces sont faites dans les mêmes moules mais qui présentent des caractéristiques en terme de maintien et de confort qui sont différentes.The construction of a sports shoe according to the invention therefore offers a very wide variety of realization: shoes with many parts municipalities where using the same molds but having a design that their own, shoes of which the pieces are made in the same molds but which have characteristics in terms of support and comfort which are different.

Dans le cas du patinage, on pourra ainsi prévoir une gamme comprenant des patins expert ayant un maximum d'éléments souples ainsi que des patins débutant dans lesquels les éléments plus rigides prédomineront et ce sans la coûteuse réalisation de nombreux moules.In the case of skating, we can thus provide a range including expert skates with a maximum of elements flexible as well as beginners skates in which the stiffer elements will prevail without the costly production of numerous molds.

La présente invention concerne également les caractéristiques qui ressortiront de la description qui va suivre en référence au dessin annexé, qui montre à titre d'exemples non limitatifs, trois modes de réalisation situés dans le domaine des patins à roulette en ligne et dans lequel :

Le chausson 9 est maintenu en place dans la tige extérieure grâce à une vis 36 qui joint la partie haute arrière du chausson 9 au collier 8. Une ouverture arrière 37 est ménagée dans le collier 8 au niveau des deux pivots 38 qui assurent la fixation de ce dernier sur le berceau 5. Cette ouverture arrière 37, alliée à la relative flexibilité du collier, constitue en fait des moyens de rappel élastique de celui-ci. Ces moyens sont sollicités par pivotement arrière du collier à partir d'une position d'équilibre inactive.The liner 9 is held in place in the outer upper thanks to a screw 36 which joins the upper rear part of the liner 9 with collar 8. A rear opening 37 is provided in the collar 8 at the two pivots 38 which ensure the fixing the latter on the cradle 5. This opening rear 37, combined with the relative flexibility of the collar, constitutes in fact elastic return means thereof. These means are biased by rear pivoting of the collar to from an inactive equilibrium position.

Accessoirement, un troisième point de fixation du collier sur le berceau est disposé à l'arrière du contrefort dans la partie la plus basse du collier. Dans ce cas, les moyens de rappel élastique sus-mentionés sont également sollicités par pivotement avant du collier. Un mécanisme de fermeture du collier constitué d'une sangle crantée et d'un levier 11 à cliquet permet d'ajuster le collier au bas de la jambe de l'utilisateur. Bien entendu, tout autre système de fermeture, par exemple à boucle velcro peut être envisagé. Incidentally, a third attachment point for the collar on the cradle is arranged at the rear of the buttress in the lowest part of the necklace. In this case, the means of above mentioned elastic recall are also requested by front pivoting of the collar. A closing mechanism collar consisting of a notched strap and a lever 11 to ratchet adjusts the collar at the bottom of the leg the user. Of course, any other closure system, for example with velcro buckle can be considered.

D'autre part, le collier peut être issu directement du berceau et rendu flexible par rapport au berceau par des fentes et / ou un découpage approprié.On the other hand, the necklace can come directly from the cradle and made flexible with respect to the cradle by slots and / or an appropriate cutting.

La figure 2 montre en perspective le berceau 5. Celui-ci comprend une semelle 12 et un contrefort 13 entourant le talon. Le matériau utilisé pour le berceau 5 est de préférence une matière plastique très rigide et sensiblement non flexible.Figure 2 shows in perspective the cradle 5. It includes a sole 12 and a buttress 13 surrounding the heel. The material used for the cradle 5 is preferably a very rigid and substantially non-flexible plastic.

Des lumières 14, 15 sont ménagées dans la semelle pour permettre la fixation de la chaussure 2 sur le châssis 3. Sur chacun des côtés du contrefort 13, une ouverture 16 donne à la partie haute du contrefort un peu de flexibilité. Des trous 17 servent à la fixation du collier sur le berceau par les pivots 38.Lights 14, 15 are provided in the sole for allow the shoe 2 to be fixed to the chassis 3. On each side of the buttress 13, an opening 16 gives the upper part of the buttress a little flexibility. Holes 17 are used to fix the collar to the cradle by the pivots 38.

Les figures 3, 4 et 8 montrent respectivement une vue de côté, une vue en perspective de dessous et une vue en perspective de dessus de la claque 6 et du plastron 7. La claque 6 est réalisée dans une matière plastique moins rigide que le berceau 5 et surtout plus flexible que celui-ci. Elle est fixée au berceau 5, d'une part au niveau de la semelle par la mise en contact d'un retour 18 et de la semelle et d'autre part par la mise en contact de la patte 19 avec le contrefort 13. Dans ce mode de réalisation, la forme donnée à la claque 6 se caractérise de la façon suivante : un embout 20 enveloppe l'extrémité du pied (zone des orteils), une très faible élévation verticale au niveau de la zone de flexion métatarsophalangienne 21 et deux brides 22 sont destinées à assurer le maintien au niveau du cou-de-pied. Des fentes 23 sont éventuellement ménagées dans l'embout 20 pour permettre l'aération du pied du patineur.Figures 3, 4 and 8 respectively show a view of side, a perspective view from below and a view in perspective from above of slap 6 and front plate 7. The slap 6 is made of a less rigid plastic than cradle 5 and above all more flexible than this one. She is fixed to the cradle 5, on the one hand at the level of the sole by bringing a return 18 and the sole and other into contact leaves by bringing tab 19 into contact with the buttress 13. In this embodiment, the shape given to slap 6 is characterized as follows: a tip 20 envelope the tip of the foot (toe area), a very weak vertical elevation at the bending zone metatarsophalangeal 21 and two flanges 22 are intended for maintain the level of the instep. Slots 23 are optionally provided in the end piece 20 to allow ventilation of the skater's foot.

Le plastron est fait d'une matière plastique ou textile très souple. Il se compose d'un ou de plusieurs empiècements qu'entoure un bord. Le bord, non visible sur le dessin, correspond à la partie du plastron qui, pour des raisons de fixation de celui-ci sur la claque 6, se superpose à celle-ci. Dans le mode de réalisation représenté, cette fixation est faite par couture. Une ouverture centrale 25 sépare le plastron 7 en un plastron latéral 29 et un plastron médial 30. Le plastron latéral 29 et le plastron médial 30 sont reliés l'un à l'autre par leur extrémité avant. Un dispositif de serrage par lacet comprenant des passants 10 fixés, de part et d'autre de l'ouverture centrale, sur le plastron permet d'ajuster le volume de la chaussure au pied de l'utilisateur. Pour rendre le plastron plus souple ainsi que pour améliorer l'aération, des entailles 27 sont ménagées sur tout ou partie du plastron. Du tissu peut être disposé à l'intérieur des entailles.The plastron is made of a plastic or textile material very flexible. It consists of one or more panels that surrounds an edge. The edge, not visible in the drawing, corresponds to the part of the plastron which, for reasons of fixing it on the slap 6, is superimposed thereon. In the embodiment shown, this attachment is made by sewing. A central opening 25 separates the faceplate 7 into a lateral faceplate 29 and a medial faceplate 30. The lateral faceplate 29 and the medial faceplate 30 are connected to each other the other by their front end. A clamping device by lace comprising loops 10 fixed, on either side of the central opening on the faceplate allows you to adjust the volume of the shoe at the foot of the user. To make the softer bib as well as to improve ventilation, notches 27 are provided on all or part of the plastron. Of fabric can be placed inside the notches.

La figure 5 montre un deuxième mode de réalisation de l'invention. Selon ce mode le collier 8 du patin 1 n'est plus fait d'une seule pièce de plastique rigide, mais de plusieurs pièces de rigidité différentes. Il comprend deux montants latéraux 31 reliés l'un à l'autre par un pont 32 qui assure la ceinture arrière du bas de la jambe de l'utilisateur. Les montants latéraux 31 sont fixés par leur extrémité inférieure au berceau 5. Un rabat 33 est fixée sur chacun des montants de façon à fermer la ceinture du bas de la jambe vers l'avant du patin.Figure 5 shows a second embodiment of the invention. According to this mode, the collar 8 of the shoe 1 is no longer made of a single piece of rigid plastic, but several pieces of different stiffness. It includes two amounts side 31 connected to each other by a bridge 32 which ensures the back belt of the user's lower leg. The lateral uprights 31 are fixed by their lower end to the cradle 5. A flap 33 is fixed to each of the uprights of way to close the belt from the bottom of the leg towards the front of the skate.

Selon l'invention, les rabats 33 sont faits d'un matériau moins rigide que le matériau des montants latéraux 31 et du pont 32, ce dernier matériau étant lui-même moins rigide que celui du berceau 5. La fermeture du collier peut se faire par n'importe quel dispositif de serrage comme par exemple une sangle crantée associée à un crochet à cliquet. Toutefois, du fait de la plus grande souplesse des rabats, on pourra utiliser un dispositif de serrage plus simple comme par exemple un système à sangle souple 24, tissée ou non, et sur lequel on fixe des bandes Velcro. Pour assurer le serrage au niveau du cou-de-pied, un dispositif de serrage par sangle 34 est fixé de part et d'autre sur les deux contreforts 13 du berceau 5. Dans ce mode de réalisation, le gradient de rigidité est réalisé à la fois au niveau de la claque et au niveau du serrage cheville.According to the invention, the flaps 33 are made of a material less rigid than the material of the lateral uprights 31 and the bridge 32, the latter material itself being less rigid than that of the cradle 5. The collar can be closed by any clamping device such as a notched strap associated with a ratchet hook. However, from makes the flaps more flexible, we can use a simpler clamping device such as for example a flexible strap system 24, woven or not, and on which fixes Velcro straps. To ensure tightening at the instep, a strap clamping device 34 is fixed on either side on the two buttresses 13 of the cradle 5. In this embodiment, the stiffness gradient is achieved at both at the level of the slap and at the level of the tightening ankle.

La figure 6 montre un troisième mode de réalisation de l'invention. Le patin 1 qui y est représenté est un patin spécialement adapté pour la pratique dite "aggressive". Dans ce type de pratique, une partie des figures acrobatiques comprennent des phases de glissement du châssis ou de la coque sur des parties dures telles que des rampes, des rails ou des surfaces en béton. Traditionnellement la chaussure de ces patins est faite d'une coque très rigide et très résistante à l'usure. Ces patins sont donc peu confortables et limitent beaucoup les mouvements de l'utilisateur. Pourtant la réalisation de certaines figures nécessite une certaine flexibilité du pied. Le berceau 5 représenté à la figure 6 remonte assez haut pour assurer une bonne protection de la cheville. De plus, dans sa partie avant elle comprend un rebord 35 s'élevant verticalement depuis la semelle 12. La claque est réalisée dans un matériau moins dur que le berceau. Elle est assez épaisse pour offrir une bonne résistance à l'usure. Le plastron 7 est réalisé dans un tissu synthétique de type mesh garant d'une excellente durabilité et favorisant la respirabilité.Figure 6 shows a third embodiment of the invention. The pad 1 shown there is a pad specially adapted for so-called "aggressive" practice. In this type of practice, part of the acrobatic figures include sliding phases of the chassis or hull on hard parts such as ramps, rails or concrete surfaces. Traditionally the shoe of these skates is made of a very rigid shell and very resistant to wear. These skates are therefore not very comfortable and limit user movements a lot. Yet the making certain figures requires some flexibility of the foot. The cradle 5 shown in Figure 6 goes up high enough to ensure good protection of the ankle. In addition, in its front part it includes a rim 35 rising vertically from the sole 12. The slap is made of a less hard material than the cradle. She is thick enough to offer good resistance to wear. The plastron 7 is made of a synthetic mesh type fabric guarantees excellent durability and promotes breathability.

La figure 7 montre une coupe partielle de la chaussure du patin montré à la figure 6. La claque 6 est fixée sur le berceau au niveau de la semelle et au niveau du contrefort talon par des rivets. Le plastron 7 est fixé sur la claque 6 par couture.Figure 7 shows a partial section of the shoe of the shoe shown in figure 6. The slap 6 is fixed on the cradle at the level of the sole and at the level of the buttress heel with rivets. The faceplate 7 is fixed on the slap 6 by sewing.

Bien entendu, la présente invention ne se limite pas aux exemples de mode de réalisation précédents qui sont présentés dans cet exposé à titre purement indicatif. Of course, the present invention is not limited to examples of previous embodiments which are presented in this presentation for information only.
