Description

Article chaussant à semelle ventilée Footwear with ventilated sole
L'invention concerne un article chaussant disposant d'une semelle ventilée.The invention relates to an article of footwear having a ventilated sole.
La marche et la station debout entraînent un gonflement et un échauffement des pieds qui cause usuellement un inconfort prononcé avec le temps. Afin de diminuer cet inconfort l'emploi de chaussures et de semelles adaptées a été recherché constamment depuis des années.Walking and standing causes swelling and heating of the feet which usually causes discomfort over time. To reduce this discomfort the use of shoes and soles adapted has been sought constantly for years.
En raison du problème d'échauffement bien identifié les chaussures sont de plus en plus prévues avec des perforations sur la face supérieure. Ces aménagements n'empêchent cependant pas un échauffement notable du pied depuis la partie plantaire qui est complètement isolée vis à vis de l'extérieur.Due to the well-identified heating problem the shoes are more and more provided with perforations on the upper side. These arrangements, however, do not prevent significant heating of the foot from the plantar part which is completely insulated with respect to the outside.
La semelle de la chaussure comporte généralement plusieurs couches de matériaux synthétiques totalement étanches, notamment en raison du nécessaire maintien d'intercalaires employés pour l'amortissement des chocs provoqués par les foulées sur le sol.The sole of the shoe generally comprises several layers of synthetic materials completely sealed, especially because of the need to maintain tabs used for damping shocks caused by strides on the ground.
Ces intercalaires amortisseurs étant par exemple des coussins d'air, des gels maintenus dans des enveloppes ou des polymères particuliers.These damping spacers are for example air cushions, gels held in envelopes or particular polymers.
La plupart des chaussures disponibles aujourd'hui présentent une structure avec des ouvertures pour aérer le dessus du pied mais la partie plantaire est confinée de manière hermétique dans le moulage de la semelle, toutes les personnes rencontrent donc le problème d'échauffement de la voûte plantaire avec les désagréments en corrélation, à savoir :Most shoes available today have a structure with openings to ventilate the top of the foot but the plantar part is hermetically confined in the molding of the sole, so all people have the problem of heating the arch. with the associated inconveniences, namely:
- gonflement important du pied avec sensation de chaleur excessive,- significant swelling of the foot with feeling of excessive heat,
- élévation de l'humidité et frottements accrus à l'intérieur de la chaussure, - accentuation de la transpiration des pieds, qui provient à 80% de la partie plantaire,- increased humidity and increased friction inside the shoe, - increased perspiration of the feet, which comes from 80% of the plantar part,
- rapide dégradation de la propreté de la semelle intérieure avec développement de bactéries et d'odeurs.- rapid deterioration of the cleanliness of the insole with development of bacteria and odors.
L'invention a donc pour objectif de résoudre ces principales difficultés en proposant un article chaussant comportant, outre l'aération classique par le dessus du chausson, une ventilation par sa partie inférieure usuellement hermétique.The invention therefore aims to solve these major difficulties by providing an article of footwear comprising, in addition to conventional ventilation by the top of the liner, ventilation by its lower part usually hermetic.
La présente invention concerne un article chaussant comprenant une structure basse localisée entre le pied et le sol formée par plusieurs semelles superposées et un dessus, chacune des semelles étant perforée, apte à laisser passer l'eau et l'air et fabriquée dans une matière synthétique lavable, lesdites semelles superposées étant respectivement :The present invention relates to an article of footwear comprising a low structure located between the foot and the ground formed by several superimposed soles and a top, each of the soles being perforated, able to let water and air and made of a synthetic material. washable, said superimposed insoles being respectively:
une semelle extérieure au contact du sol fabriquée avec un caoutchouc et/ou un polymère rigide bon absorbeur de chocs,an outsole in contact with the ground made with a rubber and / or a rigid polymer good shock absorber,
une semelle intermédiaire,a midsole,
une semelle intérieure moulée amovible et absorbant les chocs formée de préférence en deux couchesa removable and shock absorbing molded insole preferably formed of two layers
caractérisé en ce que la semelle intermédiaire est de préférence composée par au moins l'une, et avantageusement par l'assemblage, des parties suivantes :characterized in that the midsole is preferably composed of at least one, and advantageously by assembly, the following parts:
une partie formée par une membrane grillagée collée et cousue à la semelle extérieure,a part formed by a mesh membrane bonded and sewn to the outsole,
une partie formée par une membrane maillée, maintenue avec la membrane grillagée et placée au-dessus d'elle par rapport au sol, dans le cas de l'assemblage des deux parties. Ladite membrane maillée est collée et cousue à la semelle extérieure dans le cas de son utilisation seule.a portion formed by a mesh membrane, held with the mesh membrane and placed above it relative to the ground, in the case of the assembly of the two parts. Said membrane mesh is glued and sewn to the outsole in the case of its use alone.
Par article chaussant il doit être compris tout type de chaussure, par exemple de sport, de loisir, de plein air de type sandale, ou une chaussure classique pouvant être portée avec un costume.By article footwear must be understood any type of shoe, for example sport, leisure, outdoor type sandal, or a classic shoe that can be worn with a suit.
Les avantages de l'article chaussant selon l'invention sont multiples :The advantages of the article of footwear according to the invention are multiple:
la ventilation par la partie inférieure de la chaussure évite réchauffement plantaire excessif et le maintien d'un bas niveau d'humidité dans la semelle,the ventilation at the bottom of the shoe avoids excessive plantar warming and maintains a low level of moisture in the sole,
- le maintien de la partie plantaire au sec et en ventilation procure un confort élevé au marcheur,- Keeping the plantar part dry and ventilated provides high comfort to the walker,
- l'évacuation de l'humidité à la fois pendant le port de la chaussure, lors de la marche, et lorsque la chaussure n'est pas utilisée, évite le développement bactérien et les mauvaises odeurs,- evacuation of moisture both during the wearing of the shoe, when walking, and when the shoe is not used, avoids bacterial growth and unpleasant odors,
- toutes les semelles constitutives de la chaussure étant lavables et à séchages rapides l'entretien se trouve facilité,all the insoles constituting the shoe being washable and quick-drying, maintenance is facilitated,
la structure de la base de la chaussure en différentes semelles, avec des matériaux différents et des porosités variables permet de maintenir les débris et poussières hors de la chaussure tout en laissant passer l'air et l'humidité, la structure multicouche étant particulièrement efficace pour cela,the structure of the base of the shoe in different soles, with different materials and variable porosities keeps the debris and dust out of the shoe while allowing air and moisture to pass through, the multilayer structure being particularly effective for this,
la chaussure est adaptée pour contenir dès sa fabrication une semelle et un ensemble de matériaux assurant un amorti important des chocs, il n'est donc pas nécessaire au marcheur d'ajouter, comme c'est le cas la plupart du temps aujourd'hui, une semelle supplémentaire pour assurer un amortissement satisfaisant de l'onde de choc qui se répercute lors de la foulée du talon à la colonne vertébrale. D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre en regard du dessin annexé qui n'est donné qu'à titre d'exemple non limitatif.the shoe is adapted to contain from its manufacture a sole and a set of materials providing significant cushioning of shocks, it is not necessary for the walker to add, as is the case most of the time today, an additional soleplate to ensure a satisfactory damping of the shock wave that echoes during the stride of the heel to the spine. Other features and advantages of the invention will become apparent from the description which follows with reference to the accompanying drawing which is given by way of non-limiting example.
La figure 1 est une vue en coupe de l'article chaussant selon l'invention.Figure 1 is a sectional view of the footwear according to the invention.
L'article chaussant tel que décrit ci-après comprend une structure basse, c'est à dire localisée entre le pied et le sol lorsque la chaussure est portée, formée par plusieurs semelles superposées, de préférence au moins trois. Une structure de chaussure fabriquée par assemblage de plusieurs couches cousues ou collées est connue en elle-même. La partie haute de la chaussure, le dessus, qui constitue le chaussant est formée de manière traditionnelle par des pièces textiles cousues et collées entre elles et présentant une ouverture sur la face avant de manière à permettre le laçage, de manière classique.The footwear as described below comprises a low structure, that is to say located between the foot and the ground when the shoe is worn, formed by several superimposed soles, preferably at least three. A shoe structure manufactured by assembling several sewn or glued layers is known per se. The upper part of the boot, the upper, which constitutes the footwear is formed in the traditional way by textile pieces sewn and glued together and having an opening on the front face so as to allow lacing, in a conventional manner.
Une telle chaussure est représentée sur la figure 1 avec les différentes semelles constitutives de l'invention.Such a shoe is shown in Figure 1 with the different soles constituting the invention.
Selon l'invention l'article chaussant est caractérisé en ce que chacune des semelles est perforée et apte à laisser passer l'eau et l'air, et par le fait que chaque semelle est fabriquée dans une matière synthétique lavable.According to the invention the article of footwear is characterized in that each of the soles is perforated and able to pass water and air, and that each sole is made of a washable synthetic material.
L'air et l'eau peuvent circuler, tel que l'indique la flèche de la figure 1 , entre l'extérieur et l'intérieur de la chaussure, et en sens inverse, à travers les semelles.Air and water can flow, as indicated by the arrow in Figure 1, between the outside and inside of the shoe, and in the opposite direction, through the soles.
Toujours selon l'invention, et en référence à la figure 1 , les semelles sont ainsi agencées :Still according to the invention, and with reference to FIG. 1, the soles are thus arranged:
une semelle extérieure 1 au contact du sol fabriquée avec un caoutchouc et/ou un polymère rigide bon absorbeur de chocs,an outsole 1 in contact with the ground made of a rubber and / or a rigid polymer good shock absorber,
une semelle intermédiaire 2, une semelle intérieure 3 moulée amovible et absorbant les chocs formée de préférence en deux couches.a midsole 2, a molded insole 3 removable and shock absorbing preferably formed in two layers.
Selon l'invention la semelle extérieure 1 comporte au moins deux ouvertures ou fentes, et de préférence un ensemble d'ouvertures et de fentes de dimensions réduites, typiquement la longueur des ouvertures et fentes peut être de 2 à 300 millimètres et la largeur doit être limitée à 8 millimètres maximum pour éviter le passage des cailloux.According to the invention the outsole 1 comprises at least two openings or slots, and preferably a set of openings and slots of reduced dimensions, typically the length of the openings and slots can be from 2 to 300 millimeters and the width must be limited to 8 millimeters maximum to avoid the passage of pebbles.
Cette dimension réduite permet de laisser passer l'air et l'eau mais empêche les débris et graviers d'obstruer les ouvertures.This reduced size allows air and water to pass through but prevents debris and gravel from clogging the openings.
De préférence les ouvertures ou les fentes sont pratiquées dans les parties en creux 4 de la semelle extérieure 1 ,Preferably the openings or slots are made in the recessed portions 4 of the outer sole 1,
La semelle extérieure est avantageusement fabriquée avec un matériau rigide et résistant à l'abrasion tel que du néoprène EVA ou du polyuréthane, ou une combinaison de ces matériaux. De manière à améliorer cette résistance la semelle extérieure est renforcée dans les zones d'usure par des parties en caoutchouc éventuellement renforcé en carbone. Cette composition permet ainsi une meilleure absorption des chocs tout en apportant une durabilité grâce aux pièces de caoutchouc.The outsole is advantageously made of a rigid and abrasion-resistant material such as EVA neoprene or polyurethane, or a combination of these materials. In order to improve this resistance, the outsole is reinforced in the wear zones by rubber parts optionally reinforced with carbon. This composition thus provides better shock absorption while providing durability through rubber parts.
La géométrie des ouvertures et fentes incluses dans la semelle est de préférence définie de façon à ce que l'air et l'eau puissent passer de manière optimale tout en empêchant les objets ou cailloux de pénétrer par la semelle extérieure. Le choix de la géométrie des fentes prend en compte les besoins de mouvements naturels du pied, facilitant les mouvements de flexion nécessaires sur une telle chaussure. La géométrie prend également en compte la solidité générale de la semelle afin d'éviter que trop de fentes positionnées aux mauvais endroits fragilisent la semelle extérieure. La dimension et les formes des fentes sont conçues afin d'éviter l'amorce d'une déchirure de la semelle pouvant s'aggraver au fur et à mesure de l'usage. Selon l'invention la semelle intermédiaire 2 est de préférence composée par au moins l'une, et avantageusement par l'assemblage, des parties suivantes :The geometry of the openings and slots included in the soleplate is preferably defined so that air and water can pass optimally while preventing objects or pebbles from penetrating through the outsole. The choice of the geometry of the slots takes into account the needs of natural movements of the foot, facilitating the necessary bending movements on such a shoe. The geometry also takes into account the overall strength of the sole to prevent too many slots positioned in the wrong places weaken the outsole. The size and shape of the slits are designed to prevent the beginning of a tear of the soleplate that can worsen as and when use. According to the invention the intermediate sole 2 is preferably composed of at least one, and advantageously by assembly, the following parts:
une partie formée par une membrane grillagée 5 collée et cousue à la semelle extérieure 1 ,a portion formed by a mesh membrane 5 glued and sewn to the outsole 1,
- une partie formée par une membrane maillée 6, maintenue avec la membrane grillagée 5 et placée au-dessus d'elle par rapport au sol, dans le cas de l'assemblage des deux parties. Ladite membrane maillée 6 est collée et cousue à la semelle extérieure 1 dans le cas de son utilisation seule.- A portion formed by a mesh membrane 6, held with the mesh membrane 5 and placed above it relative to the ground, in the case of the assembly of the two parts. Said mesh membrane 6 is glued and sewn to the outsole 1 in the case of its use alone.
La membrane grillagée 5 permettant à l'air et l'eau un passage optimal tout en protégeant le pied des cailloux et autres objets extérieurs.The mesh membrane 5 allows air and water an optimal passage while protecting the foot pebbles and other external objects.
Le collage de l'une ou de l'autre membrane sur la semelle extérieure est réalisé de telle sorte que la colle ne soit pas enduite sur la partie de la membrane qui épouse les ouvertures et fentes de la semelle extérieure afin de ne pas boucher les perforations de la membrane.The bonding of one or the other membrane on the outsole is made in such a way that the glue is not coated on the part of the membrane that matches the openings and slots of the outsole so as not to clog the perforations of the membrane.
La membrane maillée 6 permet, pour des raisons esthétiques et de protection, de couvrir la membrane grillagée 5 tout en apportant un confort au porté. Cette semelle intermédiaire permet également le cas échéant d'insérer entre les deux membranes des pièces en latex, ou un gel, ou tout autre matériau permettant une meilleure absorption des chocs et/ou une répartition des ondes de choc, et de manière plus générale d'intégrer des inserts permettant d'optimiser le confort de la chaussure.The mesh membrane 6 makes it possible, for aesthetic and protective reasons, to cover the mesh membrane 5 while providing comfort to the wearer. This midsole also makes it possible, if necessary, to insert between the two membranes latex parts, or a gel, or any other material allowing better absorption of shocks and / or a distribution of shock waves, and more generally of integrate inserts to optimize the comfort of the shoe.
Ainsi selon l'invention il est possible d'introduire entre la membrane grillagée 5 et la membrane maillée 6 un insert permettant une absorption des chocs et/ou une répartition des ondes de choc.Thus according to the invention it is possible to introduce between the mesh membrane 5 and the mesh membrane 6 an insert for shock absorption and / or a distribution of shock waves.
Cet insert est avantageusement muni de perforations de manière à laisser circuler l'humidité et la chaleur entre l'intérieur et l'extérieur de la chaussure, au travers des différentes semelles. Selon l'invention la semelle intérieure 3 au contact avec le pied comporte les deux couches suivantes :This insert is advantageously provided with perforations so as to let moisture and heat circulate between the inside and the outside of the shoe, through the different soles. According to the invention, the insole 3 in contact with the foot comprises the following two layers:
