Description

Domaine de l'inventionField of the invention

L'invention concerne le domaine des chaussures ventilées et notamment des chaussures ventilées comprenant une semelle d'usure et une semelle de confort formant un réseau de ventilation comportant au moins un canal plantaire.The invention relates to the field of ventilated shoes and in particular ventilated shoes comprising a outsole and a comfort sole forming a ventilation network comprising at least one plantar channel.

Dans l'ensemble de la description et des revendications, le terme de « chaussure » sera compris comme tout article d'habillement permettant de chausser un pied pour le recouvrir au moins partiellement et/ou le protéger. Cet article peut remonter plus haut que la cheville et recouvrir au moins partiellement le mollet.Throughout the description and claims, the term "shoe" will be understood as any article of clothing for footwear to cover at least partially and / or protect. This article can go up above the ankle and at least partially cover the calf.

État de la techniqueState of the art

Le document EP 1 973 438 décrit une chaussure comprenant une semelle d'usure et une semelle de confort. La semelle d'usure et la semelle de confort forment un réseau de ventilation alimenté en air par des perçages latéraux réalisés dans la semelle d'usure. Le réseau de ventilation comporte dans la semelle d'usure au moins un canal longitudinal formé à partir du talon jusqu'à proximité de la pointe de la semelle d'usure. Le réseau de ventilation comporte également dans la semelle de confort des canaux transversaux sur le côté de la semelle de confort tourné vers le canal longitudinal pour conduire l'air entré dans le canal longitudinal vers la périphérie de la semelle de confort.The document EP 1 973 438 describes a shoe comprising a outsole and a comfort sole. The outsole and the comfort sole form a ventilation network supplied with air by lateral holes made in the outsole. The ventilation network comprises in the outsole at least one longitudinal channel formed from the heel to near the tip of the outsole. The ventilation network also has in the comfort sole transverse channels on the side of the comfort sole turned towards the longitudinal channel to bring air entering the longitudinal channel to the periphery of the comfort sole.

Cette chaussure est satisfaisante en termes de ventilation. Cependant, elle présente notamment l'inconvénient selon lequel de l'eau peut entrer à l'intérieur de la semelle d'usure lorsque l'utilisateur marche dans une flaque d'eau, ou en présence d'éclaboussures.This shoe is satisfactory in terms of ventilation. However, it has the particular disadvantage that water can enter the inside of the outsole when the user walks in a puddle, or in the presence of splashing.

Le document EP 2 015 649 décrit une chaussure imperméable dotée d'un système de ventilation et de transpiration. Cette chaussure comprend une semelle d'usure et une semelle de confort. Une couche de ventilation en un matériau réticulaire tridimensionnel (une mousse) est appliquée au moins sur une portion de la surface supérieure de la semelle de confort. Cette chaussure comprend également une partie supérieure et un matelassage placé à l'intérieur de la partie supérieure et contre celle-ci. Le matelassage comprend au moins un élément de ventilation en un matériau réticulaire tridimensionnel communiquant avec l'air à l'extérieur de la chaussure au niveau d'une zone haute du matelassage. L'élément de ventilation est positionné sur au moins un côté latéral de la chaussure. Cet élément de ventilation est en communication d'air avec la couche de ventilation.The document EP 2,015,649 describes a waterproof shoe with a ventilation and perspiration system. This shoe includes a outsole and a comfort sole. A ventilation layer in a three-dimensional reticulated material (a foam) is applied at least on a portion of the upper surface of the comfort sole. This shoe also comprises an upper part and a padding placed inside the upper part and against it. The quilting comprises at least one ventilation element in a three-dimensional reticular material communicating with the air outside the shoe at a high area of the quilting. The ventilation element is positioned on at least one lateral side of the shoe. This ventilation element is in air communication with the ventilation layer.

Un inconvénient d'une telle chaussure est que l'élément de ventilation est positionné sur un côté latéral de la chaussure. Ainsi, cet élément de ventilation est nécessairement souple. Lors du conditionnement avant vente de la chaussure ou lors du rangement de cette chaussure dans un meuble, la partie supérieure peut être pliée. Ceci peut entraîner une détérioration de l'élément de ventilation. Par conséquent, la ventilation de l'intérieur de la chaussure à travers l'élément de ventilation peut ne plus être assurée.A disadvantage of such a shoe is that the ventilation element is positioned on a lateral side of the shoe. Thus, this ventilation element is necessarily flexible. When conditioning the shoe before sale or when storing this shoe in a piece of furniture, the upper part can be folded. This can lead to deterioration of the ventilation element. Therefore, the ventilation of the inside of the shoe through the ventilation element may no longer be ensured.

Un autre inconvénient d'une telle chaussure et que, au niveau de la semelle, le système de ventilation comprend une couche de ventilation en un matériau en mousse. Or, la compression répétée de cette mousse peut amener celle-ci à rester comprimée diminuant ainsi l'efficacité de sa fonction de pompage.Another disadvantage of such a shoe and that, at the level of the sole, the ventilation system comprises a ventilation layer made of a foam material. However, the repeated compression of this foam can cause it to remain compressed thus decreasing the efficiency of its pumping function.

Le document US 556 825 décrit une chaussure ventilée selon le préambule de la revendication 1.The document US 556,825 discloses a ventilated shoe according to the preamble of claim 1.

Résumé de l'inventionSummary of the invention

La présente invention a pour objectif de proposer une chaussure ventilée présentant un système de ventilation plus robuste et plus efficace, et notamment qui soit simple à réaliser et qui s'oppose bien à la pénétration d'eau.The present invention aims to provide a ventilated shoe having a more robust ventilation system and more effective, and in particular that is simple to perform and is opposed to the penetration of water.

Pour cela, l'invention propose une chaussure ventilée comme spécifiée dans la revendication 1.For this, the invention provides a ventilated shoe as specified in claim 1.

Ainsi, le système de ventilation de cette chaussure ventilée formé par le réseau de ventilation au niveau des semelles, par l'orifice en partie haute du contrefort, et par le passage formé dans le contrefort, est plus robuste et efficace que ce de l'état de la technique.Thus, the ventilation system of this ventilated shoe formed by the ventilation network at the soles, the hole in the upper part of the buttress, and the passage formed in the buttress, is more robust and effective than that of the state of the art.

En effet, le contrefort est une partie relativement rigide de la chaussure. En particulier, le contrefort n'est pas sujet à une quelconque déformation lors de la marche, ni lors du conditionnement ou du rangement de la chaussure.Indeed, the buttress is a relatively rigid part of the shoe. In particular, the buttress is not subject to any deformation during walking, or during packaging or storage of the shoe.

En outre, la réalisation sous forme d'un canal plantaire dans les semelles d'une partie du système de ventilation au lieu d'une couche de ventilation en matériau réticulaire tridimensionnel permet de s'assurer de la longévité du système de ventilation et notamment de la fonction de pompage de celui-ci.In addition, the embodiment in the form of a plantar channel in the soles of a portion of the ventilation system instead of a ventilation layer of three-dimensional reticular material makes it possible to ensure the longevity of the ventilation system and in particular of the pumping function of it.

D'autres caractéristiques optionnelles et non limitatives sont :

  • la semelle de confort recouvre partiellement le passage de ventilation dans sa région arrière ;
  • le canal plantaire s'étend entre les semelles d'usure et de confort à partir d'une zone correspondant au talon jusqu'à une zone correspondant à l'articulation entre métatarses et phalanges du pied ;
  • le canal plantaire, au voisinage du talon définit une chambre de pompage formée dans la semelle d'usure, la chambre de pompage étant alimentée en air par le passage d'air ;
  • la chambre de pompage présente localement une hauteur plus grande que le reste du canal plantaire ; et
  • le contrefort est étanche à l'eau.
Other optional and non-limiting features are:
  • the comfort sole partly covers the ventilation passage in its rear region;
  • the plantar channel extends between the soles of wear and comfort from an area corresponding to the heel to an area corresponding to the articulation between the metatarsal and phalanges of the foot;
  • the plantar canal, in the vicinity of the heel defines a pumping chamber formed in the outsole, the pumping chamber being supplied with air by the air passage;
  • the pumping chamber locally has a height greater than the rest of the plantar canal; and
  • the buttress is waterproof.

Description détailléedetailed description

Une chaussure ventilée 1 est décrite ci-après en référence aux figures 1 à 3. Les termes « longitudinal » et « transversal » doivent être compris par rapport à une direction reliant une zone de la chaussure 1 correspondant au talon et une zone de la chaussure 1 correspondant aux orteils.A ventilated shoe 1 is described hereinafter with reference to Figures 1 to 3 . The terms "longitudinal" and "transverse" must be understood with respect to a direction connecting an area of the shoe 1 corresponding to the heel and an area of the shoe 1 corresponding to the toes.

La chaussure ventilée 1 comprend une semelle d'usure 2 et une semelle de confort 3 disposée au-dessus de la semelle d'usure 2. La chaussure ventilée 1 comprend également une tige 4 fixée à la semelle d'usure 2. Une doublure intérieure 6 recouvre la tige 4 à l'intérieur de la chaussure 1. Les semelles de confort 3 et d'usure 2 protègent la plante du pied. Dans une partie non visible, la tige 4 recouvre et protège le dessus du pied.The ventilated shoe 1 comprises a outsole 2 and a comfort sole 3 disposed above the outsole 2 . The ventilated shoe 1 also comprises a rod 4 attached to the outsole 2 . An inner liner 6 covers the rod 4 inside the boot 1 . Comfort 3 and wear 2 insoles protect the sole of the foot. In an invisible part, the rod 4 covers and protects the top of the foot.

Au niveau de l'emboîtage 42 de la chaussure, celle-ci comprend un contrefort 41 qui renforce l'emboîtage par l'extérieur.At the level of the casing 42 of the boot, it comprises a buttress 41 which reinforces the casing from the outside.

La chaussure ventilée 1 comprend également un système de ventilation défini conjointement par les semelles 2, 3.The ventilated shoe 1 also comprises a ventilation system defined jointly by the soles 2 , 3 .

La semelle d'usure 2 et la semelle de confort 3 forment ainsi un réseau de ventilation 21, 31 comportant au moins un canal plantaire 21.The outsole 2 and the comfort sole 3 thus form a ventilation network 21 , 31 comprising at least one plantar channel 21 .

Le ou chaque canal plantaire 21 d'extension longitudinale s'étend entre les semelles d'usure 2 et de confort 3 à partir d'une zone correspondant au talon jusqu'à une zone correspondant à l'articulation entre métatarses et phalanges du pied.The or each plantar canal 21 of longitudinal extension extends between the wear soles 2 and comfort 3 from an area corresponding to the heel to an area corresponding to the articulation between the metatarsal and phalanges of the foot.

Le canal plantaire 21, au niveau de la zone correspondant au talon, définit une chambre de pompage formée entre la semelle d'usure 2 et la semelle de confort 3, la chambre de pompage étant alimentée en air par un passage d'air 45 formé entre le contrefort 41 et l'emboîtage 42 de la chaussure. Cet effet de pompage est facilité par un accroissement de la hauteur de l'espace entre la semelle d'usure et la semelle de confort au voisinage de l'entrée du passage d'air 45. La chambre de pompage aide ainsi à la circulation de l'air entre l'intérieur et l'extérieur de la chaussure 1. La chambre de pompage peut avoir diverses formes selon le matériau de la semelle de confort 3. La forme de la chambre de pompage (par exemple annulaire ou cylindrique) et le matériau de la semelle de confort 3 sont choisis pour assurer une fermeté sous le talon de l'utilisateur tout en optimisant la fonction de pompage recherchée.The plantar canal 21 , at the level of the zone corresponding to the heel, defines a pumping chamber formed between the outsole 2 and the comfort sole 3 , the pumping chamber being supplied with air by an air passage 45 formed between the buttress 41 and the casing 42 of the shoe. This pumping effect is facilitated by increasing the height of the space between the outsole and the comfort sole in the vicinity of the inlet of the air passage 45 . The pumping chamber thus helps the flow of air between the inside and the outside of the shoe 1 . The pumping chamber can have various shapes depending on the material of the comfort soleplate 3 . The shape of the pumping chamber (for example annular or cylindrical) and the material of the comfort sole 3 are chosen to ensure a firmness under the heel of the user while optimizing the desired pumping function.

Le ou chaque canal plantaire 21 est de préférence formé dans la semelle d'usure 2, sur la surface tournée vers l'intérieur de la chaussure 1. Le canal plantaire 21 forme donc un sillon dans la semelle d'usure 2. En outre, des canaux transversaux 31 peuvent être formés de préférence dans la semelle de confort 3 sur la surface tournée vers la semelle d'usure 2. Ces canaux transversaux 31 formant des sillons permettent de faire circuler l'air entre les canaux 21 et jusqu'à la périphérie de la semelle de confort 3 et assurer ainsi la ventilation de l'ensemble de la plante du pied.The or each plantar channel 21 is preferably formed in the outsole 2 , on the surface facing the interior of the shoe 1 . The plantar canal 21 thus forms a groove in the outsole 2 . In addition, transverse channels 31 may preferably be formed in the comfort sole 3 on the surface facing the outsole 2 . These transverse channels 31 forming grooves make it possible to circulate the air between the channels 21 and up to the periphery of the comfort sole 3 and thus ensure ventilation of the entire sole of the foot.

La semelle d'usure 2 et/ou la semelle de confort 3 peuvent être venues de moulage avec les sillons formés sur les surfaces correspondantes.The outsole 2 and / or the sole comfort 3 may be molded with the grooves formed on the corresponding surfaces.

Le contrefort 41 comporte au moins un orifice 43 dans sa partie haute, le contrefort 41 et l'emboîtage 42 formant deux membranes, respectivement extérieure et intérieure. Des éléments d'espacement 44 sont prévus entre ces deux membranes.The buttress 41 has at least one orifice 43 in its upper part, the buttress 41 and the casing 42 forming two membranes, respectively outer and inner. Spacer elements 44 are provided between these two membranes.

La membrane intérieure 42 est ainsi la membrane la plus proche de l'intérieur de la chaussure 1. La membrane extérieure 41 est la membrane au contact de l'air ambiant. La membrane extérieure 41 est de préférence essentiellement étanche à l'eau. Si un matelassage 5 est prévu dans l'emboîtage de la chaussure 1, celui-ci est placé contre la membrane intérieure 42 à l'intérieur de l'espace recevant le pied, le matelassage 5 se situant entre la doublure intérieure 6 et la membrane intérieure 42.The inner membrane 42 is thus the membrane closest to the inside of the boot 1 . The outer membrane 41 is the membrane in contact with the ambient air. The outer membrane 41 is preferably substantially watertight. If a padding 5 is provided in the casing of the shoe 1 , it is placed against the inner membrane 42 inside the space receiving the foot, the padding 5 being located between the inner lining 6 and the membrane interior 42 .

Les éléments d'espacement 44 séparent les deux membranes 41, 42 pour former entre elles le passage d'air 45 s'étendant sur la hauteur de l'emboîtage. L'orifice 43 relie l'extérieur de la chaussure 1 au passage d'air 45, c'est-à-dire qu'il est formé à travers le contrefort 41.The spacers 44 separate the two membranes 41 , 42 to form between them the air passage 45 extending over the height of the casing. The orifice 43 connects the outside of the boot 1 to the air passage 45 , that is to say that it is formed through the buttress 41 .

L'emboîtage 42 et le contrefort 41 ne sont pas arrêtés au niveau de la semelle d'usure 2. Il sont recourbés vers la direction longitudinale de la semelle d'usure 2 afin de mettre en communication de fluide le passage d'air 45 et le canal plantaire 21 au niveau d'une extrémité généralement horizontale dudit passage, formé donc par la continuation des membranes 41 et 42 jusqu'au canal plantaire 21. Le rôle du passage 45 est ainsi de permettre la circulation de l'air du haut de l'emboîtage jusqu'au canal plantaire 21, formé par exemple dans la semelle d'usure 2, sous la semelle de confort 3. On notera ici que la région arrière de la semelle de confort 3 recouvre les membranes 41 et 42 formant la terminaison du passage 45 côté canal plantaire 21.The casing 42 and the buttress 41 are not stopped at the level of the outsole 2 . They are bent towards the longitudinal direction of the outsole 2 in order to put in fluid communication the passage of air 45 and the plantar canal 21 at a generally horizontal end of said passage, formed therefore by the continuation of the membranes 41 and 42 to the plantar canal 21 . The role of the passage 45 is thus to allow the flow of air from the top of the casing to the plantar channel 21 , formed for example in the outsole 2 , under the comfort sole 3 . It will be noted here that the rear region of the comfort sole 3 covers the membranes 41 and 42 forming the termination of the passage 45 on the plantar canal side 21 .

L'emboîtage 42 doté de son contrefort 41 est un élément plus rigide que les côtés latéraux de la tige 4 et ne se déforme pas aisément lors de la marche ni lors du conditionnement de la chaussure 1 avant commercialisation ou lors de son rangement dans un meuble. La formation du passage d'air 45 à l'intérieur du contrefort permet de s'assurer que le passage d'air 45 ne s'obstrue pas aisément. En effet, si le passage d'air 45 était formé sur les côtés latéraux de la tige 4, le passage d'air 45 pourrait être déformé et sa fonction altérée.The casing 42 with its buttress 41 is a more rigid element than the lateral sides of the rod 4 and does not easily deform when walking or when conditioning the shoe 1 before marketing or when stored in a cabinet . The formation of the air passage 45 inside the buttress makes it possible to ensure that the passage of air 45 does not clog easily. Indeed, if the air passage 45 was formed on the lateral sides of the rod 4 , the air passage 45 could be deformed and its function altered.

En outre, le passage d'air 45 peut s'étendre sur une grande partie du contrefort 41, augmentant le volume d'air pouvant entrer à l'intérieur de la chaussure 1.In addition, the air passage 45 may extend over a large part of the buttress 41 , increasing the volume of air that can enter the interior of the shoe 1 .

Le système de ventilation 21, 31, 43, 45 de la chaussure 1 permet une circulation de l'air à partir de l'extérieur de la chaussure 1 vers l'intérieur via l'orifice 43, le passage d'air 45 et le canal plantaire 21, et dans l'autre sens.The ventilation system 21 , 31 , 43 , 45 of the boot 1 allows air to circulate from the outside of the boot 1 inwards via the orifice 43 , the air passage 45 and the plantar canal 21 , and in the other direction.

Les éléments d'espacement 44 sont une pluralité d'organes saillants 441, par exemple des picots, maintenant espacées les deux membranes 41, 42. Ces éléments saillants 441 peuvent être individualisés et fixés séparément sur une face interne d'une des membranes 41, 42, ou sur les deux faces internes en vis-à-vis. Ces éléments saillants 441 peuvent encore être reliés les uns aux autres et former un élément d'espacement 44 d'un seul tenant. Un tel élément d'espacement 44 d'un seul tenant est fixé sur une face interne, par rapport au passage d'air 45, d'une des membranes 41, 42.The spacers 44 are a plurality of projecting members 441 , for example spikes, now spaced apart the two membranes 41 , 42 . These projecting elements 441 can be individualized and fixed separately on an inner face of one of the membranes 41 , 42 , or on the two inner faces facing each other. These projecting elements 441 can still be connected to each other and form a spacing element 44 in one piece. Such a spacing element 44 in one piece is fixed on an inner face, with respect to the air passage 45 , of one of the membranes 41 , 42 .

En variante, les éléments saillants 44, qu'ils soient individualisés ou liés les uns aux autres peuvent encore être fixés sur les faces internes des deux membranes 41, 42.As a variant, the salient elements 44 , whether individualized or linked to each other, can still be fixed on the internal faces of the two membranes 41 , 42 .

Les éléments saillants 441 ont, de préférence, une hauteur comprise entre 1 mm et 5 mm, permettant d'assurer au passage d'air 45 une largeur du même ordre.The salient elements 441 preferably have a height of between 1 mm and 5 mm, to ensure the passage of air 45 a width of the same order.

Avantageusement, les éléments saillants 441 remplissent une fonction de chicane, limitant les risques de pénétration d'eau dans le passage d'air 45 notamment lorsqu'on marche dans une flaque ou que la chaussure est exposée à des éclaboussures.Advantageously, the salient elements 441 perform a baffle function, limiting the risks of penetration of water in the air passage 45 especially when walking in a pool or the shoe is exposed to splashing.

Les membranes 41, 42 sont de préférence en cuir naturel ou artificiel, en toile étanche, en caoutchouc, etc. et ont une épaisseur comprise par exemple entre 0,3 mm et 1 mm.The membranes 41 , 42 are preferably made of natural or artificial leather, waterproof canvas, rubber, etc. and have a thickness of, for example, between 0.3 mm and 1 mm.

L'orifice 43 ou chaque orifice 43 peut être situé au-dessus du niveau des chevilles. Ainsi, si l'utilisateur marche dans une flaque d'eau, son pied reste au sec tant que le niveau de l'eau ne dépasse pas celui des orifices 43.The orifice 43 or each orifice 43 may be located above the level of the pegs. Thus, if the user walks in a puddle, his foot remains dry as the water level does not exceed that of the holes 43 .

Dans le cas où ce dispositif est utilisé pour une botte, le système de ventilation 21, 31, 43, 45 peut être prolongé jusqu'en haut de la tige 4, c'est-à-dire que la structure avec le contrefort 41 peut être utilisée pour la tige 4 à l'arrière de la botte jusqu'en haut de celle-ci. Alternativement, elle peut s'arrêter à une hauteur intermédiaire de la botte.In the case where this device is used for a boot, the ventilation system 21 , 31 , 43 , 45 can be extended to the top of the rod 4 , that is to say that the structure with the buttress 41 can be used for the rod 4 at the back of the boot to the top of it. Alternatively, it can stop at an intermediate height of the boot.

En outre, le positionnement de l'orifice en position haute a pour avantage de ne pas nécessiter l'utilisation de matériaux de haute technicité (par exemple étanche à l'eau mais perméable à l'air), ce qui permet de diminuer le coût de fabrication.In addition, the positioning of the orifice in the raised position has the advantage of not requiring the use of high-tech materials (for example waterproof but permeable to air), which reduces the cost Manufacturing.

Enfin, selon l'invention, on peut choisir les matériaux des différentes parties de la chaussure 1 parmi une gamme de matériaux vaste et variée. Notamment, on ne restreint pas le choix des matériaux formant la semelle de confort 3 parmi les matériaux réticulaires adaptés à la circulation d'air au travers de ceux-ci. En outre, il n'est pas indispensable nécessaire que les deux membranes 41, 42 soient étanches à l'air, l'essentiel étant de favoriser une circulation d'air à travers le passage 45.Finally, according to the invention, the materials of the different parts of the shoe 1 can be chosen from a wide and varied range of materials. In particular, it does not restrict the choice of materials forming the comfort sole 3 among the reticular materials adapted to the flow of air through them. In addition, it is not essential that the two membranes 41 , 42 are airtight, the main thing being to promote a flow of air through the passage 45 .
