Description

La présente invention concerne le domaine des articles chaussants, tels que les chaussures, les bottes, les bottines ou analogues, et a pour objet un tel article chaussant muni d'un dispositif d'isolation.The present invention relates to the field of footwear, such as shoes, boots, ankle boots or the like, and relates to such a footwear article provided with an isolation device.

Actuellement, de nombreuses personnes, notamment dans le milieu industriel, portent les mêmes chaussures ou articles chaussants analogues sans interruption pendant des durées importantes, par exemple huit heures ou plus. Il en résulte des risques élevés de contraction de mycoses ou d'autres affections épidermiques, parasitaires ou non, des pieds, ou encore une desquamation de la peau de la plante des pieds et, à tout le moins, une sensation de brûlure et d'inconfort, notamment pour les personnes sujettes à une sudation pédieuse abondante.Currently, many people, especially in the industrial environment, wear the same shoes or similar footwear without interruption for long periods, for example eight hours or more. This results in high risks of contracting mycoses or other epidermal diseases, parasitic or not, of the feet, or even flaking of the skin of the soles of the feet and, at the very least, a burning sensation and discomfort, especially for people prone to profuse sweating.

Une solution proposée par les fabricants d'articles chaussants a consisté à réaliser des perçages dans la tige à des endroits déterminés, notamment au niveau de la partie avant de l'article chaussant.One solution proposed by the manufacturers of footwear consisted in making holes in the upper at determined locations, in particular at the level of the front part of the footwear.

Toutefois, une telle solution n'est pas satisfaisante, du fait qu'elle ne permet pas, d'une part, de créer une circulation d'air ou une ventilation sous la plante des pieds, notamment dans la région des orteils et de la zone d'appui en arrière de ces derniers ni, d'autre part, d'isoler la plante des pieds contre les dégagements de chaleur dus à la marche.However, such a solution is not satisfactory, because it does not, on the one hand, create air circulation or ventilation under the soles of the feet, especially in the region of the toes and the support area behind the latter or, on the other hand, to isolate the soles of the feet against the release of heat due to walking.

Or, les articles chaussants, qui sont pourvus d'une semelle d'usure moulée directement sur la tige, entraînent généralement les risques d'affection les plus élevés et génèrent les sensations d'inconfort les plus prononcées.However, footwear, which is provided with a molded outsole directly on the upper, generally entails the highest risk of affection and generates the most pronounced feelings of discomfort.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un article chaussant caractérisé en ce qu'il est pourvu d'un dispositif d'isolation disposé sous la semelle première.It has, in fact, for an article of footwear characterized in that it is provided with an insulation device disposed under the sole.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence au dessin schématique annexé, dont la figure unique est une vue en élévation latérale et en coupe partielle d'un article chaussant conforme à l'invention.The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the attached schematic drawing, the single figure of which is a view. in side elevation and in partial section of a footwear according to the invention.

La figure unique du dessin annexé représente un article chaussant 1 comportant une semelle d'usure 2, une semelle première 3 et une tige 4.The single figure of the appended drawing represents an article of footwear 1 comprising a outsole 2, a first sole 3 and a upper 4.

Conformément à l'invention, cet article chaussant 1 est avantageusement pourvu d'un dispositif d'isolation 5 disposé sous la semelle première 3.According to the invention, this footwear item 1 is advantageously provided with an insulation device 5 arranged under the first sole 3.

Le dispositif d'isolation 5 est constitué, de préférence, par un élément allongé 6, avantageusement disposé au moins sous la zone d'appui de la plante du pied de l'utilisateur et délimitant, sous la semelle première 3, au moins un espace d'air.The insulation device 5 preferably consists of an elongated element 6, advantageously disposed at least under the support area of the sole of the user's foot and delimiting, under the first sole 3, at least one space of air.

Cet élément allongé 6 se présente sous forme d'une fausse semelle fixée par sa périphérie 7, par soudage, collage ou couture sur la face inférieure de la semelle première 3 et munie de moyens d'écartement 8, de préférence sous forme de nervures, délimitant avec ladite semelle première 3 des espaces d'air.This elongate element 6 is in the form of a false sole fixed by its periphery 7, by welding, gluing or sewing on the underside of the first sole 3 and provided with spacing means 8, preferably in the form of ribs, delimiting with said first sole 3 air spaces.

Selon une caractéristique de l'invention, les moyens d'écartement 8 s'étendent transversalement à l'axe longitudinal de l'élément allongé 6. Ainsi, la flexibilité longitudinale de l'élément allongé 6 est assurée, de sorte qu'il ne constitue aucune entrave à la flexibilité de l'ensemble de l'article chaussant, la flexion résultant de la marche ayant uniquement pour effet de modifier la géométrie des espaces entre les nervures 8.According to a characteristic of the invention, the spacing means 8 extend transversely to the longitudinal axis of the elongate element 6. Thus, the longitudinal flexibility of the elongate element 6 is ensured, so that it does not constitutes no obstacle to the flexibility of the entire footwear item, the bending resulting from walking only having the effect of modifying the geometry of the spaces between the ribs 8.

Il est également possible, selon une variante de réalisation de l'invention, de prévoir des moyens 8 s'étendant parallèlement à l'axe longitudinal de l'élément allongé 6.It is also possible, according to an alternative embodiment of the invention, to provide means 8 extending parallel to the longitudinal axis of the elongate element 6.

Afin d'améliorer la flexibilité de l'élément allongé 6, les moyens 8 sous forme de nervures sont avantageusement munis d'au moins une interruption sous forme de découpe réalisant une communication avec l'espace d'air voisin délimité par le moyen 8, ou nervure, suivant ou précédant.In order to improve the flexibility of the elongate element 6, the means 8 in the form of ribs are advantageously provided with at least one interruption in the form of a cutout providing communication with the neighboring air space delimited by the means 8, or rib, next or previous.

Le dispositif 5 conforme à l'invention permet une isolation de la plante du pied contre le dégagement de chaleur se produisant lors de la marche du fait du frottement entre la semelle d'usure 2 et la semelle première 3, par création d'une poche d'air isolante sous la plante du pied.The device 5 according to the invention allows insulation of the sole of the foot against the release of heat occurring during walking due to the friction between the outsole 2 and the outsole 3, by creating a pocket insulating air under the sole of the foot.

Conformément à une autre caractéristique de l'invention, la semelle première 3 est pourvue de perforations 9 sur tout ou partie de sa surface s'étendant au-dessus du ou des espaces d'air délimités par les moyens 8 ou nervures prévus sur l'élément allongé 6. Ainsi, lors de chaque flexion, au cours de la marche, l'air comprimé entre la semelle première 3 et la semelle d'usure 2 peut s'échapper à travers les perforations 9 dans l'article chaussant et être à nouveau aspiré entre les moyens 8 après ladite flexion.According to another characteristic of the invention, the first sole 3 is provided with perforations 9 over all or part of its surface extending above the air space or spaces defined by the means 8 or ribs provided on the elongated element 6. Thus, during each flexion, during walking, the compressed air between the first sole 3 and the outsole 2 can escape through the perforations 9 in the footwear and be at again sucked between the means 8 after said bending.

En outre, la prévision de ce dispositif d'isolation 5 permet une réduction du rayon de courbure de la semelle d'usure et une réduction de l'épaisseur de cette dernière au niveau dudit dispositif 5. Il en résulte que, dans le cas d'une réalisation de la semelle d'usure 2 par injection, par exemple de polyuréthanne, celle-ci peut être réduite au niveau dudit dispositif 5.In addition, the provision of this isolation device 5 allows a reduction in the radius of curvature of the outsole and a reduction in the thickness of the latter at said device 5. It follows that, in the case of an embodiment of the outsole 2 by injection, for example of polyurethane, this can be reduced at the level of said device 5.

Selon une autre caractéristique de l'invention, le ou les espaces délimités entre la semelle première 3 et l'élément allongé 6 peuvent être partiellement remplis d'un matériau solide à action désodorisante et/ou déssicante ayant des effets prolongés dans le temps. Ainsi, il est possible de traiter simultanément les problèmes de transpiration et de dégagement d'odeurs correspondant.According to another characteristic of the invention, the space or spaces delimited between the first sole 3 and the elongate element 6 can be partially filled with a solid material with deodorant and / or desiccant action having effects prolonged over time. Thus, it is possible to simultaneously deal with the problems of perspiration and corresponding odor development.

Conformément à une autre variante de réalisation de l'invention, non représentée au dessin annexé, l'élément allongé 6 peut être pourvu, d'une part, d'une partie de fermeture supérieure délimitant avec la partie inférieure une outre plate et, d'autre part, d'un moyen d'aspiration à clapet et d'un moyen de refoulement également à clapet, lesdits moyens débouchant respectivement, le moyen d'aspiration à l'extérieur de l'article chaussant ou à l'intérieur de ce dernier et le moyen de refoulement, sous forme de buses, sous la plante du pied et/ou les orteils, ainsi qu'éventuellement près du talon. Un tel mode de réalisation permet de combiner l'effet d'isolation du dispositif 5 avec un effet de circulation d'air et de renouvellement de ce dernier dans l'article chaussant au cours de la marche.In accordance with another alternative embodiment of the invention, not shown in the accompanying drawing, the elongated element 6 can be provided, on the one hand, with an upper closing part delimiting with the lower part a flat addition and, d 'on the other hand, a valve suction means and a discharge means also valve, said means opening respectively, the suction means outside the footwear or inside this last and the means of repression, in the form of nozzles, under the sole of the foot and / or the toes, as well as possibly near the heel. Such an embodiment makes it possible to combine the insulating effect of the device 5 with an effect of air circulation and renewal of the latter in the footwear during walking.

La circulation d'air ou ventilation générée par le dispositif 5 ainsi constitué est particulièrement importante dans le cas d'un déplacement de l'utilisateur, du fait des variations importantes de la pression exercée par le pied de l'utilisateur sur la semelle première 3, simultanément à la flexion de cette dernière, lors de la prise d'appui du pied.The air circulation or ventilation generated by the device 5 thus formed is particularly important in the case of movement of the user, due to the significant variations in the pressure exerted by the foot of the user on the first sole 3 , simultaneously with the bending of the latter, when the foot is supported.

La distribution de l'air sous la plante du pied et/ou sous les orteils peut être réalisée par des moyens d'amenée et de distribution d'air, sous la forme de canaux, de cannelures ou de rainures, convergeant vers les zones concernées.The distribution of air under the sole of the foot and / or under the toes can be carried out by means of air supply and distribution, in the form of channels, grooves or grooves, converging towards the areas concerned. .

Il est également possible, selon une autre variante de réalisation de l'invention non représentée au dessin annexé, de combiner le dispositif d'isolation 5 avec une pompe de circulation d'air disposée dans la partie de talon de la semelle et reliée par un conduit à l'espace d'air délimité par l'élément allongé 6, ladite pompe aspirant de l'air à l'extérieur de l'article chaussant ou à l'intérieur de ce dernier. Ainsi, il est possible de réaliser une circulation forcée d'air à l'intérieur de l'article chaussant, avec ou sans régénération dudit air, qui est délivré sous la plante du pied et/ou les orteils à travers les perforations 9.It is also possible, according to another alternative embodiment of the invention not shown in the accompanying drawing, to combine the isolation device 5 with an air circulation pump arranged in the heel part of the sole and connected by a conduit to the air space delimited by the elongated element 6, said pump sucking air outside the or inside the shoe. Thus, it is possible to carry out a forced circulation of air inside the footwear, with or without regeneration of said air, which is delivered under the sole of the foot and / or the toes through the perforations 9.

La semelle d'usure 2 peut être réalisée en mousse de polyuréthanne et présenter une structure mono-couche ou multicouches à densité variable.The outsole 2 can be made of polyurethane foam and have a monolayer or multilayer structure with variable density.

Grâce à l'invention, il est possible de réaliser un article chaussant permettant une isolation de la plante du pied contre des dégagements de chaleur se produisant lors de la marche par suite du frottement entre les semelles première et d'usure et permettant éventuellement, en outre, une aération de la plante du pied et/ou des orteils. De plus, l'invention prévoit également une possibilité de traitement des exsudations et/ou des odeurs. Il en résulte une amélioration notable du confort pour l'utilisateur et une diminution importante des risques de contraction d'affections pédieuses.Thanks to the invention, it is possible to produce an article of footwear allowing insulation of the sole of the foot against heat emissions occurring during walking as a result of friction between the first and wearing soles and possibly allowing, in in addition, ventilation of the sole and / or toes. In addition, the invention also provides a possibility of treatment of exudations and / or odors. This results in a noticeable improvement in comfort for the user and a significant reduction in the risks of contracting foot diseases.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. Modifications remain possible, notably from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
