Description

La présente invention concerne les semelles pour articles chaussants et a pour objet une telle semelle comportant un dispositif amortisseur.The present invention relates to soles for footwear and has for object such a sole having a damping device.

Les semelles de ce type ont pour but de procurer un meilleur confort de marche, une moindre sensation de fatigue et d'assurer l'absorption des chocs.The soles of this type are intended to provide a better walking comfort, a lesser feeling of fatigue and ensure the absorption of shocks.

Plusieurs solutions existent aujourd'hui pour amortir les chocs dus au contact de la semelle avec le sol.Several solutions exist today to cushion shocks due to the contact of the sole with the ground.

Une première solution consiste à insérer entre les différentes couches constituant la semelle, à savoir la semelle d'usure, la première de montage et la première de propreté, une couche en un matériau amortissant. Cette réalisation présente, toutefois, l'inconvénient d'alourdir la chaussure et d'augmenter la hauteur de la semelle, rendant ainsi son utilisation moins agréable.A first solution is to insert between the various layers constituting the sole, namely the outsole, the first mounting and the first clean, a layer of damping material. This embodiment has, however, the disadvantage of weighing down the shoe and increasing the height of the sole, thus making its use less pleasant.

Une autre solution consiste à insérer un coussin d'air dans le talon de la chaussure. Ici se pose le problème de la protection de la chambre à air. En effet, elle risque de se dégonfler et de perdre son efficacité lorsque l'utilisateur marche sur un objet pointu ou tranchant.Another solution is to insert a cushion of air in the heel of the shoe. Here arises the problem of the protection of the inner tube. Indeed, it may deflate and lose its effectiveness when the user walks on a sharp or sharp object.

De nombreuses autres solutions ont été proposées. Ainsi, le document FR-A-2 577 119 décrit une semelle de chaussure munie d'un dispositif restituteur d'énergie. Ici, la semelle comporte un piston monté coulissant dans une chemise au niveau du talon et en saillie par rapport à la surface du talon. Or, cette réalisation présente un inconvénient majeur, à savoir que le dispositif destiné à restituer l'énergie est gênant pour la marche, car le marcheur sent, à chaque pas, ce dispositif s'enfoncer dans le talon. De plus, ledit dispositif entraîne de très forts risques de déstabilisation et de chute et ne convient pas pour une utilisation sur des terrains non homogènes et accidentés.Many other solutions have been proposed. Thus, the document FR-A-2,577,119 describes a shoe sole provided with a device for energy recovery. Here, the sole comprises a piston slidably mounted in a liner at the heel and projecting from the heel surface. However, this embodiment has a major drawback, namely that the device for restoring energy is troublesome for walking, because the walker feels at each step, this device sink into the heel. In addition, said device entails very high risk of destabilization and falling and is not suitable for use on inhomogeneous and uneven terrain.

Une autre solution est proposée dans le document US-A-4 616 431 concernant une semelle pour chaussure de sport, dans laquelle sont montés des dispositifs d'absorption des chocs sous forme de disques insérés dans des cylindres, un piston étant monté dans chacun desdits cylindres pour exercer une pression contre lesdits disques dans des conditions de charge, c'est-à-dire lorsque le pied repose sur le sol. Cette réalisation n'est pas convaincante car l'amortissement est limité, du fait que les disques sont superposés et que l'amortissement dépend de la possibilité de compression desdits disques.Another solution is proposed in the document US-A-4,616,431 relating to a sole for a sports shoe, in which shock absorbing devices in the form of discs inserted in cylinders are mounted, a piston being mounted in each of said cylinders for exerting pressure against said discs in load conditions, that is to say when the foot rests on the ground. This realization is not convincing because the damping is limited, because the disks are superimposed and damping depends on the possibility of compression of said disks.

Il en est de même pour les dispositifs décrits dans les documents DE-A-29 01 084 , FR-A-2 774 565 , US-B1-6 176 025 et EP-A-0 399 332 , dans lesquels les éléments destinés à absorber les chocs présentent une capacité de déformation relativement faible limitant leur efficacité.It is the same for the devices described in the documents DE-A-29 01 084 , FR-A-2,774,565 , US-B1-6 176 025 and EP-A-0 399 332 , wherein the shock absorbing elements have a relatively low deformation capacity limiting their effectiveness.

Le brevet français n° 2 731 597 au nom de la demanderesse, décrit un dispositif amortisseur permettant d'améliorer cette capacité d'absorption des chocs, dans lequel un insert est monté dans le talon de la semelle, cet insert étant constitué d'éléments sous forme de picots destinés à être comprimés lors de la marche. Cette réalisation présente des limites du fait que les picots présentent une forme relativement petite et du fait qu'ils sont disposés de manière assez dense, ce qui ne favorise pas leur déformation et donc leur capacité d'absorption des chocs. Le dispositif selon ce document est plutôt destiné à améliorer le confort au niveau du talon qu'à absorber les chocs.The patent French No. 2,731,597 in the name of the applicant, discloses a damping device for improving this shock absorption capacity, in which an insert is mounted in the heel of the sole, this insert consisting of elements in the form of pins to be compressed when walking. This embodiment has limitations because the pins have a relatively small shape and because they are arranged in a fairly dense manner, which does not promote their deformation and therefore their shock absorbing capacity. The device according to this document is rather intended to improve the comfort at the heel to absorb shock.

La présente invention a notamment pour but d'améliorer encore l'amortissement, de surmonter les inconvénients cités plus haut et de proposer une solution permettant de réaliser une semelle comportant un dispositif amortisseur, réalisant une absorption importante des chocs indépendamment des terrains empruntés, en particulier sur les terrains non uniformes, et dont l'insertion dans la semelle ne modifie pas la forme de cette dernière, qui garde son efficacité, même lorsque ledit dispositif est percé. En outre, ce dispositif peut être utilisé dans de nombreux types de chaussures.The present invention is intended in particular to further improve the damping, to overcome the drawbacks mentioned above and to propose a solution for producing a sole comprising a damping device, achieving a significant absorption of shocks independently of the terrain used, in particular on uneven ground, and whose insertion into the sole does not change the shape of the latter, which keeps its effectiveness, even when said device is pierced. In addition, this device can be used in many types of shoes.

A cet effet, elle a pour objet une semelle pour article chaussant selon la revendication 1.For this purpose, it relates to a footwear sole according to claim 1.

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 aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en coupe longitudinale de la semelle selon un mode de réalisation de l'invention, et
  • la figure 2 est une vue de dessous simplifiée de la semelle selon un autre mode de réalisation de l'invention.
The invention will be better understood, thanks to the following description, which refers to a preferred embodiment, given by way of non-limiting example, and explained with reference to the attached schematic drawings, in which:
  • the figure 1 is a longitudinal sectional view of the sole according to one embodiment of the invention, and
  • the figure 2 is a simplified bottom view of the sole according to another embodiment of the invention.

La figure 1 des dessins annexés représente, à titre d'exemple, une semelle qui est essentiellement constituée par une première de propreté 1, une première de montage 2 et une semelle d'usure 3 et qui comporte au moins un dispositif amortisseur 4.The figure 1 By way of example, the accompanying drawings represent a soleplate which essentially consists of a first cleanliness element 1, a first assembly element 2 and a wear soleplate 3 and which comprises at least one damping device 4.

Conformément à l'invention, ce dispositif amortisseur 4 peut être un insert ou élément élastiquement déformable, inséré dans ladite semelle et sous forme d'un corps moulé constitué par des pièces tubulaires 4', fermées à une extrémité, espacées mutuellement et reliées au niveau de leur extrémité ouverte à une embase 4" commune.According to the invention, this damping device 4 may be an insert or elastically deformable element, inserted in said sole and in the form of a molded body consisting of tubular parts 4 ', closed at one end, mutually spaced and connected at the from their open end to a common base 4 ".

L'insert ou élément élastiquement déformable est, de préférence, monté dans la semelle de montage 2. Cette réalisation du dispositif amortisseur 4 en tant qu'insert permet d'introduire ce dernier dans toutes les semelles d'articles chaussants par simple prévision dans leur semelle d'un logement destiné à recevoir ledit dispositif amortisseur 4. Cette caractéristique est avantageuse, car elle permet de standardiser la fabrication de semelles munies de tels dispositifs 4 et favorise ainsi la réduction des coûts de fabrication de ces semelles.The insert or elastically deformable element is preferably mounted in the mounting flange 2. This embodiment of the damping device 4 as an insert makes it possible to introduce the latter into all the insoles of footwear simply by predicting in their sole of a housing for receiving said damping device 4. This feature is advantageous because it allows to standardize the manufacture of soles provided with such devices 4 and thus promotes the reduction of manufacturing costs of these soles.

Selon l'invention, l'embase 4" commune présente une jupe périphérique 4''' délimitant une chambre logeant les extrémités fermées des pièces tubulaires 4'. On obtient ainsi un dispositif amortisseur présentant une structure alvéolaire à déformation parfaitement dirigée qui favorise la stabilité de la chaussure et permet de réaliser une absorption des chocs d'une manière totalement uniforme et verticale.According to the invention, the common base 4 "has a peripheral skirt 4 '' 'defining a chamber housing the closed ends of the tubular parts 4', thereby obtaining a damping device having a perfectly directed deformation structure which promotes stability of the shoe and makes it possible to achieve shock absorption in a totally uniform and vertical manner.

Conformément à l'invention, l'élément 4 élastiquement déformable est disposé dans un réceptacle souple 6 fermé de manière étanche par un couvercle 7.According to the invention, the elastically deformable element 4 is disposed in a flexible receptacle 6 sealingly closed by a cover 7.

Le matériau constitutif dudit corps moulé 4 élastiquement déformable peut être avantageusement choisi en fonction de ses propriétés d'amortissement et d'absorption des chocs.The constituent material of said elastically deformable molded body 4 may advantageously be chosen according to its damping and shock absorption properties.

Afin d'atteindre un amortissement optimal des chocs, et selon un mode de réalisation préféré de l'invention, le réceptacle souple 6 peut former une chambre périphérique verticale autour du corps moulé 4 élastiquement déformable et ledit corps moulé 4 élastiquement déformable peut être en contact avec le couvercle 7 et avec la partie du réceptacle souple 6 opposée audit couvercle 7.In order to achieve optimal shock absorption, and according to a preferred embodiment of the invention, the flexible receptacle 6 can form a vertical peripheral chamber around the molded body 4 elastically deformable and said elastically deformable molded body 4 can be in contact with the lid 7 and with the portion of the flexible receptacle 6 opposite said lid 7.

Cette chambre périphérique verticale permet, en effet, d'améliorer l'amortissement des chocs car, en plus de se déformer lors du choc, elle est séparée du corps moulé 4, élastiquement déformable, par un volume, dans lequel ledit corps moulé 4 peut se déformer entièrement et librement lors d'un choc, sans être gêné par les parois du réceptacle souple 6 et, de ce fait, absorber en douceur l'énergie relative au choc.This vertical peripheral chamber makes it possible, in fact, to improve the shock absorption because, in addition to being deformed during impact, it is separated from the molded body 4, elastically deformable, by a volume, in which said molded body 4 can to deform completely and freely during an impact, without being obstructed by the walls of the flexible receptacle 6 and, therefore, gently absorb the energy relative to the impact.

La partie du réceptacle souple 6 opposée au couvercle 7 peut avantageusement présenter un dispositif 8 de centrage et de maintien du corps moulé 4 élastiquement déformable permettant d'assurer le bon fonctionnement du dispositif amortisseur 4. En effet, le dispositif 8 de centrage et de maintien du corps moulé 4 élastiquement déformable garantit un positionnement stable dudit corps moulé 4 dans le réceptacle souple 6 et assure ainsi un amortissement uniforme des chocs au niveau du corps moulé 4 et, de ce fait, l'efficacité du dispositif amortisseur.The portion of the flexible receptacle 6 opposite the cover 7 may advantageously have a device 8 for centering and holding the molded body 4 elastically deformable to ensure the proper operation of the damping device 4. Indeed, the device 8 for centering and holding the molded body 4 elastically deformable ensures stable positioning of said molded body 4 in the flexible receptacle 6 and thus ensures a uniform shock absorption of the molded body 4 and, therefore, the effectiveness of the damping device.

Selon une caractéristique de l'invention, le dispositif 8 de centrage et de maintien du corps moulé 4 élastiquement déformable peut avantageusement se présenter sous la forme d'une cuvette centrale, ménagée dans la partie du réceptacle souple 6 opposée au couvercle 7 et épousant intimement le contour du corps moulé 4 élastiquement déformable sur une partie de sa hauteur.According to one characteristic of the invention, the device 8 for centering and holding the elastically deformable molded body 4 can advantageously be in the form of a central bowl, formed in the portion of the flexible receptacle 6 opposite the lid 7 and intimately matching the contour of the molded body 4 elastically deformable over part of its height.

Selon une variante de réalisation de l'invention, non représentée, le dispositif 8 de centrage et de maintien du corps moulé 4 élastiquement déformable, dans la partie du réceptacle souple 6 opposée au couvercle 7, peut également être réalisé sous la forme d'une partie en saillie pénétrant de manière centrée dans le corps moulé 4 élastiquement déformable.According to an alternative embodiment of the invention, not shown, the device 8 for centering and holding the elastically deformable molded body 4, in the part of the flexible receptacle 6 opposite to the lid 7, can also be made in the form of a projecting portion penetrating centrally in the molded body 4 elastically deformable.

Selon un autre mode de réalisation, non représenté, le corps moulé 4 élastiquement déformable peut être en contact intime avec la surface intérieure du réceptacle souple 6. Dans ce cas, lors d'un choc, le réceptacle souple 6 n'entrave pas la déformation du corps moulé 4 élastiquement déformable et se déforme lui-même du fait de ses propriétés élastiques.According to another embodiment, not shown, the elastically deformable molded body 4 can be in intimate contact with the In this case, during an impact, the flexible receptacle 6 does not hinder the deformation of the molded body 4 which is elastically deformable and deforms itself because of its elastic properties.

Selon l'invention, la semelle d'usure est pourvue d'un élément inférieur 9 de protection du réceptacle 6 élastiquement déformable, intégré à ladite semelle d'usure par moulage. Cet élément 9 assure la protection du réceptacle 6 élastiquement déformable contre l'usure lors de la marche, et également contre la pénétration de salissures telles que la poussière, l'eau, ou autres.According to the invention, the outsole is provided with a lower element 9 for protecting the resiliently deformable receptacle 6, integrated with said molded wear sole. This element 9 protects the receptacle 6 elastically deformable against wear during walking, and also against the penetration of dirt such as dust, water, or other.

En fonction de l'utilisation de la chaussure et des besoins de son utilisateur, et selon un mode de réalisation de l'invention, au moins un élément 4 élastiquement déformable peut être avantageusement inséré dans la partie de talon 5 de la semelle.Depending on the use of the shoe and the needs of its user, and according to one embodiment of the invention, at least one elastically deformable element 4 may advantageously be inserted into the heel portion 5 of the sole.

Pour absorber les chocs au niveau de la partie avant du pied, et selon un autre mode de réalisation de l'invention, au moins un élément 4 élastiquement déformable peut être inséré dans la semelle, au niveau de l'un des trois points d'appui 10, 11 et 12 formant le triangle de sustentation de l'avant du pied (voir figure 2).To absorb shocks at the forefoot part, and according to another embodiment of the invention, at least one elastically deformable element 4 can be inserted into the sole at one of the three points of the foot. support 10, 11 and 12 forming the triangle of levitation of the forefoot (see figure 2 ).
