Abstract

The present invention relates to a sole incorporating, in the bearing zone of the heel, a pump 3 for ventilating the shoe. According to the invention, under the bearing surface located at the periphery of the pump 3, pads 8, made from a material which is much more compressible than the mass of the sole 2, are incorporated, the compressible pads 8 are preferably distributed in the form of a plurality of volumes 8a, b, c which are independent in order to prevent transmission of the compression pressure between them, and the arch support also incorporates a pad 12 made from compressible material. The invention increases the capacity of the pump and improves the comfort of the shoe. <IMAGE>

Description

Semelle incorporant une pompe d'aération de la chaussure. Sole incorporating a pump ventilation of the shoe.

On a déjà proposé dans de nombreux brevets tels que FR-A-1.024.960, It has been proposed in numerous patents such as FR-A-1024960,
FR-A-854.986, etc. FR-A-854 986, etc. d'incorporer dans une semelle une cavité qui refoule, lors de la mise en appui du pied, une partie du volume d'air qu'elle contient à l'intérieur de la tige de la chaussure, l'aspiration de l'air, généralement l'air extérieur, pour remplir le volume utile de la pompe s'effectuant lors du soulèvement du pied sous l'effet de l'élasticité propre de l'enceinte constituant la pompe, de l'élasticité du matériau constituant la semelle dans laquelle est noyée ladite enceinte ou de ressorts prévus dans ou autour de la pompe. incorporating into a sole a cavity which discharges, when the weight bearing foot, a portion of the volume of air contained in it is inside the upper of the boot, the air intake, generally outdoor air, to fill the working volume of the pump taking place during lifting of the foot under the effect of the elasticity proper of the enclosure constituting the pump, the elasticity of the material constituting the sole wherein is embedded said enclosure or springs provided in or around the pump.

Le fonctionnement d'une telle pompe et son incorporation dans une semelle, notamment réalisée par moulage d'une matière thermoplastique ou d'un caoutchouc synthétique, posent des problèmes techniques. The operation of such a pump and its incorporation into a sole, in particular produced by molding of a thermoplastic material or a synthetic rubber, pose technical problems. Si le matériau constitutif de la semelle est compressible et réalisé par exemple en mousse de plastique, la semelle va théoriquement s'affaisser suffisamment sous l'effet de la pression du pied pour autoriser une variation de volume appréciable de la cavité constituant la pompe. If the material of the sole is compressible and made for example of plastic foam, the sole will theoretically sufficient sag under the effect of the pressure of the foot to permit an appreciable variation in volume of the cavity constituting the pump. Une telle semelle n'assure toutefois pas, du fait de sa compressibilité importante, un appui suffisamment stable pour le pied et il y a des risques de compression dissymétrique avec basculement latéral.En outre la cavité constituant la pompe tend à s'étaler par enfoncement de ses parois latérales en meme temps qu'elle perd de la hauteur de sorte que son volume varie moins que-proportionnellement à sa perte de hauteur. Such sole does not guarantee, because of its high compressibility, a sufficiently stable support for the foot and there are risks compression asymmetrical with latéral.En tilting further cavity constituting the pump tends to spread by depressing of its side walls at the same time it loses height such that its volume varies less than-proportionally to its height loss.

Ayant probablement observé ce phénomène, US-A-3.225.463 a proposé d'insérer dans la couche de la semelle se trouvant au-dessus de la cavité un insert en dôme aplati ayant une flexibilité sensiblement moindre que celle de la couche surmontant la cavité formant pompe et de placer également, en-dessous de ladite cavité, un insert moins flexible qui a pour but de maintenir la cavité formant la pompe dans sa configuration d'origine. Having observed this phenomenon probably, US-A-3,225,463 has proposed to insert the layer of the sole is situated above the cavity in a flattened dome insert having a substantially less flexibility than the layer overlying the cavity a pump and also placed, below said cavity, a less flexible insert which is intended to maintain the cavity pump to its original configuration. La solution de US-A-3.225.463 ne s'applique pas à une semelle en un matériau relativement rigide et le volume de pompage est toujours défini par la réduction d'épaisseur, sous la pression du pied, de la masse de matériau constituant la semelle. The solution of US-A-3,225,463 does not apply to a sole of a relatively rigid material and the pumping volume is always defined by the reduction in thickness, under the pressure of the foot, of the mass of material constituting the sole.

La présente invention a pour but de résoudre les divers problèmes ci-dessus rappelés que l'on rencontre dans les semelles incorporant une cavité de pompage dont la variation de volume sous la presion du pied doit être aussi importante que possible. The present invention aims to solve the various problems above recalled encountered in the soles incorporating a pump cavity whose volume change under the presion foot should be as large as possible.

L'invention a en conséquence pour objet une semelle incorporant, dans la zone d'appui du talon, une pompe d'aération de la chaussure caractérisée en ce que, sous la surface d'appui située à la périphérie de la pompe, sont incorporés des coussinets en un matériau présentant une plus grande compressibilité que la masse de la semelle. The invention accordingly relates to a sole incorporating, into the support of the heel area, an air pump of the shoe characterized in that under the supporting surface at the periphery of the pump, are incorporated pads of a material having greater compressibility than the mass of the sole.

Avec la réalisation conforme à l'invention, le degré d'enfoncement de la paroi supérieure délimitant le volume de la pompe sera fonction de la compressibilité des coussinets et la pression développée dans leur masse s' opposera à une dilatation transversale de l'enceinte constituant la pompe. With the embodiment according to the invention, the degree of depression of the upper wall defining the volume of the pump will depend on the compressibility of the pads and the pressure developed in their mass s' oppose a transverse expansion of the enclosure being the pump. En outre le matériau de la semelle qui entoure la pompe et les coussinets ayant une bonne stabilité dimensionnelle sous la pression du pied, en fait une stabilité dimensionnelle identique à celle des semelles classiques, les coussinets seront également maintenus contre un fluage latéral susceptible de provoquer un mauvais appui du pied. Further sole material of which surrounds the pump and the pads having a good dimensional stability under foot pressure, in fact identical dimensional stability than conventional soles, bearings will also be maintained against a side flow may cause a bad foot support.

Selon un mode de réalisation préférentiel les coussinets compressibles sont répartis en une pluralité de volumes indépendants pour éviter une transmission entre eux de la pression de compression. According to a preferred embodiment the compressible pads are divided into a plurality of independent volumes to avoid transmission therebetween of the compression pressure. Cette caractéristique évite un déplacement de la matière compressible les constituant de la zone la plus comprimée vers la zone moins comprimée avec le basculement en résultant de la partie de la semelle de propreté surmontant la pompe et les coussinets, basculement qui nuirait au confort. This feature prevents movement of the compressible material constituting the most compressed region to the less compressed zone with the resulting tilting of the portion of the insole overlying the pump and pads, failover causing discomfort.

Du fait de la présence des coussinets compressibles conformes à l'invention, le calcaneum va venir, lors de la mise en appui du pied, occuper une position plus basse de quelques millimètres que celle dans une semelle classique en le même matériau sans coussinets compressibles. Due to the presence of compressible bushings according to the invention, the calcaneus will come, when setting foot support, occupy a lower position than a few millimeters in a standard sole of the same material without compressible pads. Si donc la semelle comporte comme souvent une partie renflée formant soutien de voûte plantaire, ce soutien de voûte plantaire va former un mamelon en saillie anormale entre les deux zones avant et arrière d'appui du pied et il va en résulter une pression accrue sous la zone métatarsienne, pression accrue qui nuira au confort. If therefore the sole comprises as often a bulged portion forming support arch, this arch support will form a nipple abnormal protrusion between the two areas of support front and rear of the foot and it will result in increased pressure in the metatarsal area, increased pressure will hurt comfort. Pour y remédier et conformément à l'invention, le soutien de voûte plantaire incorpore également un coussinet en un matériau compressible. To correct and in accordance with the invention, the arch support pad also incorporates a compressible material.

Selon un mode de réalisation préférentiel et pour faciliter leur mise en place dans le moule d'injection de la semelle, les enceintes constituant la pompe et les coussinets compressibles sont solidaires pour former un insert unique. According to a preferred embodiment and to facilitate their introduction into the injection mold of the sole, the speakers constituting the pump and the elastic pads are integral to form a single insert.

Les enceintes constituant les coussinets peuvent être remplis de gaz compressible, ce gaz pouvant éventuellement être incorporé dans une mousse. Pregnant constituting the pads may be filled with compressible gas, this gas may optionally be incorporated into a foam. On peut également envisager de les remplir d'un liquide ou d'un gel mais, ces substances étant incompressibles, les enceintes formant les coussinets seront alors de préférence en communication avec une enceinte non noyée dans la semelle, de préférence des enceintes formant poches logées dans la partie de la tige emboîtant la partie arrière du pied comme décrit dans le brevet de la demanderesse FR-A-2.472.364, les sections de passage des communications entre chambres étant suffisamment grandes pour ne pas freiner le déplacement du liquide ou du gel. It is also conceivable to fill the liquid or gel, but these substances are incompressible, pregnant forming the pads will then preferably in communication with a chamber not embedded in the sole, preferably pregnant forming pockets accommodated in the part of the rod engaging the rear part of the foot as described in patent application FR-A-2472364, the flow sections of the communication between chambers being large enough not to hinder the movement of the liquid or gel .

La pompe peut être de tout type connu. The pump may be of any known type.

On décrira ci-après un exemple de réalisation de l'invention avec référence au dessin ci-annexé dans lequel: Will be described hereinafter an embodiment of the invention with reference to the accompanying drawing wherein:
La figure 1 est une vue en coupe longitudinale de la Figure 1 is a longitudinal sectional view of the
chaussure; shoe; la figure 2 est une vue en plan de la partie Figure 2 is a plan view of the portion
arrière de la semelle montrant la disposition des rear of the sole showing the arrangement of
coussinets et la figure 3 en est une vue en coupe trans pads and Figure 3 is a cross-sectional view
versale. versale.

Dans les dessins, la référence 1 désigne la tige et la référence 2 la semelle en matière plastique moulée par injection, la matière de la semelle pouvant etre du chlorure de polyvinyle, du polou- réthane,du caoutchouc synthétique, etc. In the drawings, reference 1 designates the stem and reference 2 the sole molded plastic injection, the material of the sole can be polyvinyl chloride, réthane polou-, synthetic rubber, etc.

Dans le moule a été placé avant l'injection, pour être noyé dans la partie de la semelle correspondant au talon,un élément central 3 ayant de préférence une forme à peu près cylindrique et fermé à sa partie supérieure par une membrane souple. In the mold was placed prior to injection, to be embedded in the portion of the sole corresponding to the heel, a central element 3 preferably having a form substantially cylindrical and closed at its upper part by a flexible membrane. et convexe 4. 4 and convex.

L'élément central est relié à l'extérieur de la semelle par un conduit 5 débouchant par une valve 6 munie ou non d'un clapet d'obturation; The central element is connected to the outside of the sole by a conduit 5 opening by a valve 6 provided or not with a valve shutter; cet élément 3 permet d'aspirer l'air à l'intérieur de la cavité et de le refouler 9 l'intérieur de la tige par exemple à travers l'orifice 7 obturé par une membrane, non représentée, réalisée en une matière légèrement perméable à l'air, de fa çon à permettre à l'air aspiré de se diffuser également à l'inté-* rieur de la chaussure pendant la marche. this element 3 can suck air inside the cavity and discharging the inside 9 of the stem, for example through the orifice 7 closed off by a membrane, not shown, made of a slightly permeable material air, fa con to allow air also drawn to diffuse the integrated * laughing shoe while walking.

Plusieurs coussinets 8 sont répartis autour de l'élément central décrit ci-dessus et séparés de celui-ci au moyen de cloisons étanches telles que des soudures 9. Ces coussinets forment des chambres indépendantes étanches. Several pads 8 are distributed around the central member described above and separated therefrom by means of bulkheads such as welds 9. These pads form watertight independent rooms. Les chambres 8a, 8b et 8c sont réparties autour de l'élément central 3 de façon qu en s'écrasant sous la force d'appui du talon, elles permettent un enfoncement de la partie supérieure de l'élément central 3 obturé par la membrane 6 malgré la stabilité de forme relative de l'ensemble de la semelle 2. The chambers 8a, 8b and 8c are arranged around the central element 3 so that crashing under the bearing force of the bead, they allow a penetration of the upper portion of the central 3 closed by the membrane element 6 despite the relative shape stability of the entire sole 2.

Dans le mode de réalisation illustré, les coussinets 8a et 8b sont remplis d'un gaz compressible et le coussinet 8c d'un liquide pour mettre en oeuvre simultanément l'objet de FR-A-2.472.354. In the illustrated embodiment, the pads 8a and 8b are filled with a compressible gas and a liquid bearing 8c to implement simultaneously the object of FR-A-2472354.

A cet effet le coussinet 8c est relié par un conduit large 10 à une chambre 11 qui emboîte la partie arrière du pied, le liquide chassé de la chambre 8 gonfle la chambre 11 qui maintient, comme exposé dans le brevet ci-dessus, le talon emboîté dans le contrefort de talon. To this end 8c pad is connected by a wide conduit 10 to a chamber 11 which engages the rear part of the foot, the liquid expelled from the chamber 8 inflates the chamber 11 which holds, as stated in the above patent, the heel fitted in the heel counter. Bien évidemment la chambre 8c pourrait également être limitée à la surface d'appui du talon et etre remplie d'un gaz compressible. Obviously 8c chamber could also be limited to the bearing surface of the heel and be filled with a compressible gas.

Un coussinet 12 est également prévu dans le soutien de voûte plantaire 13 pour que la déformation par compression de ce coussinet assure un soutien élastique de la voûte plantaire et évite l'apparition d'un point dur sous le métatarse lors de l'affaissement par compresion de l'élément central 5 et des coussinets 8. A pad 12 is also provided in the arch support 13 so that the deformation by compression of the pad provides resilient support of the arch and prevents the occurrence of a hard spot in the metatarsus upon collapse by compresion of the central element 5 and pads 8.
