Description

La présente invention concerne une semelle ou première de chaussu­re avec circulation d'un fluide incorporé du type décrit dans FR-A-­2.591.441 dans laquelle la surface inférieure de la semelle forme une chambre écrasable sous la pression du pied prenant appui sur ladite semelle, ladite chambre étant subdivisée par les lamelles transversales inclinées dont l'arête est indépendante de la feuil­le ou plaque déformable fermant ladite chambre et constituant la surface inférieure de la semelle, cette chambre communiquant aux extrémités avant et arrière de la semelle avec une chambre réali­sée sur la surface supérieure de la semelle et fermée de façon étanche par une feuille ou plaque mince, les deux chambres étant remplies d'un fluide.The present invention relates to a sole or first shoe with circulation of an incorporated fluid of the type described in FR-A-2,591,441 in which the lower surface of the sole forms a chamber which can be crushed under the pressure of the foot resting on said sole. , said chamber being subdivided by inclined transverse lamellae whose edge is independent of the deformable sheet or plate closing said chamber and constituting the lower surface of the sole, this chamber communicating at the front and rear ends of the sole with a chamber produced on the upper surface of the sole and tightly closed by a thin sheet or plate, the two chambers being filled with a fluid.

Dans la semelle décrite dans FR-A-2.591.441 les arêtes des lamel­les de la chambre inférieure font saillie au-dessus du plan infé­rieur du bord périphérique, la feuille mince fermant la chambre in­férieure étant, au repos, gonflée dans sa partie centrale au-des­sus des arêtes des lamelles. D'autre part, la chambre supérieure est également munie de lamelles inclinées dont l'arête est indépen­dante de la feuille ou plaque mince déformable fermant ladite cham­bre supérieure, ces lamelles étant inclinées dans la direction in­verse de celles de la chambre inférieure.In the sole described in FR-A-2,591,441, the edges of the lamellae of the lower chamber protrude above the lower plane of the peripheral edge, the thin sheet closing the lower chamber being, at rest, inflated in its central part at - above the edges of the slats. On the other hand, the upper chamber is also provided with inclined lamellae whose edge is independent of the deformable sheet or thin plate closing said upper chamber, these lamellae being inclined in the opposite direction to those of the lower chamber.

Dans la pratique, il s'est avéré que la circulation du fluide dans la chambre supérieure au contact de la plante du pied, circula­tion qui assure l'effet de massage que l'on recherche avec ce ty­pe de semelle, était freinée par les lamelles prévues dans cette chambre du fait que lesdites lamelles étaient tendues entre les deux côtés du rebord périphérique et en appui sur toute leur lon­gueur contre la feuille mince de fermeture, elle-même tendue dans le cadre que constitue le rebord. En outre la surface supérieure du rebord périphérique est reliée à la plaque constituant la sépa­ration entre les chambres supérieure et inférieure par une surfa­ce, sur laquelle aboutissent les lamelles, qui est perpendiculai­re à ladite surface supérieure et à ladite plaque. Lors du souda­ge de la feuille souple sur la surface supérieure du rebord, la soudure déborde au-dessus de la chambre en formant un bourrelet de quelques millimètres, ce qui réduit la surface active de la semel­le au contact de la plante du pied et s'avère inconfortable à l'u­ sage. En outre, lors de la soudure du bord périphérique de la feuille mince sur la surface supérieure ou inférieure plane étroi­te du rebord, il s'est avéré difficile d'obtenir avec certitude une soudure étanche.In practice, it has been found that the circulation of the fluid in the upper chamber in contact with the sole of the foot, a circulation which provides the massage effect which is sought with this type of sole, is slowed down by the lamellae. provided in this chamber due to the fact that said strips were stretched between the two sides of the peripheral rim and pressed over their entire length against the thin closure sheet, itself stretched in the frame formed by the rim. In addition, the upper surface of the peripheral rim is connected to the plate constituting the separation between the upper and lower chambers by a surface, on which the lamellae end, which is perpendicular to said upper surface and to said plate. When welding the flexible sheet on the upper surface of the rim, the weld overflows above the chamber, forming a bead of a few millimeters, which reduces the active surface of the sole in contact with the sole of the foot and s' turns out to be uncomfortable in the u wise. In addition, when welding the peripheral edge of the thin sheet on the narrow flat upper or lower surface of the rim, it has proved difficult to obtain with certainty a sealed weld.

Pour remédier au freinage de la circulation du fluide sous l'ac­tion de la rigidité des lamelles tendues, on a imaginé de rendre le côté des lamelles indépendant du rebord en réalisant une fente fine entre le rebord et l'extrémité y raccordée de la lamelle. L'effet de cette fente peut toutefois se trouver annulé par un point de collage entre le bourrelet de soudure de la feuille sou­ple sur la surface du rebord périphérique et l'arête de la lamel­le. Si l'indépendance de la lamelle par rapport au rebord est main­tenue, le fluide trouve un passage préférentiel de moindre résis­tance au droit de la fente, ce qui réduit la circulation de flui­de dans la partie centrale où le contact avec la plante du pied est maximum.To remedy the braking of the circulation of the fluid under the action of the rigidity of the stretched strips, it has been imagined to make the side of the strips independent of the flange by making a fine slit between the flange and the connected y end of the strip. The effect of this slot can however be canceled by a bonding point between the weld bead of the flexible sheet on the surface of the peripheral rim and the edge of the strip. If the independence of the lamella with respect to the rim is maintained, the fluid finds a preferential passage of least resistance at the right of the slit, which reduces the circulation of fluid in the central part where the contact with the sole of the foot is maximum .

La présente invention a pour but de remédier à ces inconvénients. Conformément à l'invention, la surface supérieure du rebord péri­phérique est réunie à la surface supérieure de la plaque séparatri­ce par une surface inclinée. Avec cette réalisation, le bourrelet de soudure se trouve déporté latéralement, ce qui accroît la surfa­ce de la feuille souple au contact de la plante du pied.The present invention aims to remedy these drawbacks. According to the invention, the upper surface of the peripheral rim is joined to the upper surface of the separating plate by an inclined surface. With this embodiment, the weld bead is offset laterally, which increases the surface of the flexible sheet in contact with the sole of the foot.

Pour obtenir une soudure parfaitement étanche entre la surface su­périeure ou inférieure du rebord périphérique et la feuille mince de fermeture de la chambre, on donne à ladite surface du rebord une section convexe. Avec cette caractéristique la partie centra­le convexe de la surface du rebord est écrasée élastiquement, ce qui assure une meilleure thermosoudure dans la partie centrale de la bande selon laquelle s'effectue la soudure.To obtain a perfectly sealed weld between the upper or lower surface of the peripheral rim and the thin sheet for closing the chamber, said surface of the rim is given a convex section. With this characteristic, the convex central part of the rim surface is elastically crushed, which ensures better heat-sealing in the central part of the strip according to which the welding takes place.

Selon une autre caractéristique, le côté d'une lamelle de la cham­bre supérieure est solidaire de la surface inclinée voisine du re­bord périphérique par une partie amincie dont la largeur est sensi­blement égale à la hauteur de la lamelle. Cette caractéristique fait disparaitre la rigidité de la lamelle qui freinait la circula­tion du fluide et conserve néanmoins la continuité du barrage cons­titué par chaque lamelle, ce qui amène le fluide à circuler de pré­férence dans la partie centrale où se produit surtout le contact entre la feuille souple supérieure et la plante du pied.According to another characteristic, the side of a strip of the upper chamber is secured to the inclined surface adjacent to the peripheral rim by a thinned part whose width is substantially equal to the height of the strip. This characteristic removes the rigidity of the strip which slows down the circulation of the fluid and nevertheless retains the continuity of the dam formed by each strip, which causes the fluid to circulate preferably in the central part where the contact between the flexible sheet mainly occurs. upper and the sole of the foot.

Enfin le remplissage en liquide des chambres supérieure et infé­rieure de la semelle est effectué par un orifice qui traverse le rebord, de préférence au droit de la chambre arrière réalisée pour la mise en intercommunication des chambres inférieure et supérieu­re, et après remplissage ledit orifice est fermé par un bouchon.Finally the liquid filling of the upper and lower chambers of the sole is carried out by an orifice which crosses the rim, preferably in line with the rear chamber produced for the interconnection of the lower and upper chambers, and after filling said orifice is closed by a plug.

L'invention sera décrite plus en détail ci-après sous forme d'un exemple de réalisation préférentiel avec référence au dessin ci-an­nexé dans lequel:

  • la figure 1 est une vue en plan de la surface supérieu­re de la semelle, la feuille souple étant enlevée; la fi­gure 2 en est une vue en coupe transversale et la figu­ re 3 en est une vue en coupe longitudinale partielle.
The invention will be described in more detail below in the form of a preferred embodiment with reference to the accompanying drawing in which:
  • Figure 1 is a plan view of the upper surface of the sole, the flexible sheet being removed; Figure 2 is a cross-sectional view and the figure re 3 is a partial longitudinal section view thereof.

Dans les dessins, la référence 1 désigne la plaque constituant le corps de la semelle qui est entouré par un bord périphérique 2. Sur la face supérieure du corps 1, le bord périphérique est en saillie en 3 par rapport à ladite face d'une hauteur très supérieu­re à la hauteur 4 du même bord périphérique par rapport à la face inférieure. Conformément à la présente invention, le bord inté­rieur du bord périphérique 3 qui fait saillie sur la face supérieu­re, est chanfreiné en 5. Les surfaces supérieure et inférieure 6 du bord périphérique 2 sont bombées.In the drawings, the reference 1 designates the plate constituting the body of the sole which is surrounded by a peripheral edge 2. On the upper face of the body 1, the peripheral edge projects in 3 from said face by a height much greater than the height 4 of the same peripheral edge relative to the lower face. According to the present invention, the inner edge of the peripheral edge 3 which projects from the upper face, is chamfered at 5. The upper and lower surfaces 6 of the peripheral edge 2 are curved.

Le corps 1 est interrompu à l'avant pour créer entre lui et le bord périphérique 2 une fenêtre d'intercommunication 7 entre les chambres supérieure et inférieure et il en est de même à l'arriè­re où est formée une fenêtre 8. Des barrettes 9-10 sont réalisées dans les fenêtres 7 et 8 pour éviter toute déformation du bord pé­riphérique 2 au droit desdites fenêtres sous l'effet de la mise en pression du fluide remplissant la cavité de la semelle, fluide qui est mis en circulation pour assurer un massage de la plante du pied.The body 1 is interrupted at the front to create between it and the peripheral edge 2 an intercommunication window 7 between the upper and lower chambers and it is the same at the rear where a window 8 is formed. Bars 9 -10 are made in windows 7 and 8 to avoid any deformation of the peripheral edge 2 in line with said windows under the effect of the pressurization of the fluid filling the cavity of the sole, fluid which is circulated to provide a massage of the sole of the foot.

La face supérieure du corps 1 est garnie de lamelles 11 inclinées vers l'arrière dont l'arête libre dépasse légèrement le plan du bord périphérique 12 qui constitue la surface supérieure du re­bord 2.The upper face of the body 1 is furnished with slats 11 inclined towards the rear, the free edge of which slightly exceeds the plane of the peripheral edge 12 which constitutes the upper surface of the rim 2.

Conformément à la présente invention, les lamelles 11 présentent une partie centrale 13 de section triangulaire assurant à la lamel­le un rappel élastique dans sa forme d'origine lorsqu'elle n'est pas comprimée et les deux extrémités de la lamelle sont réunies au bord périphérique 3 et à sa partie chanfreinée 5 par un voile plus mince 14 dont la largeur est sensiblement égale à la hauteur de la lamelle 11.According to the present invention, the lamellae 11 have a central portion 13 of triangular section ensuring the lamella an elastic return in its original shape when it is not compressed and the two ends of the lamella are joined to the peripheral edge 3 and to its chamfered part 5 by a veil thinner 14 whose width is substantially equal to the height of the strip 11.

La face inférieure du corps est elle garnie de lamelles 15 dont l'arête fait saillie d'une manière plus prononcée que pour les la­melles 11 par rapport à la surface inférieure 16 du bord périphéri­que 2.The lower face of the body is lined with strips 15, the edge of which projects more sharply than for the strips 11 relative to the lower surface 16 of the peripheral edge 2.

Deux feuilles minces 17 et 18, respectivement pour la surface supé­rieure et la surface inférieure, sont placées au-dessus des lamel­les 11-15 et soudées sur leur périphérie sur les faces 6 du bord périphérique 2. En ce qui concerne la feuille mince supérieure 17, celle-ci est soudée uniquement sur la surface bombée 19 subsis­tant à la périphérie du chanfrein 5 et le bourrelet de soudure qui est susceptible de se produire le long des bords des zones de sou­dure se trouve cantonné dans l'angle entre ledit chanfrein 5 et la feuille mince 17. Il ne réduit donc pas la surface active de la fa­ce supérieure de la semelle qui, avec la forme spécifique des la­melles 11, se situe au droit des arêtes des parties 13 des lamel­les. Les surfaces 6 sur lesquelles les feuilles minces 17 et 18 sont solidarisées par thermo-soudure avec le bourrelet 2, étant bombées, la pression qui est créée au centre de la bande de soudu­re est plus élevée que le long des bords de la bande du fait de la compressibilité du matériau constituant le bourrelet 2 et on ob­ tient de ce fait une soudure plus résistante et plus étanche. L'ensemble du volume compris entre les deux feuilles et le bord pé­riphérique 2 est rempli d'un fluide compressible ou incompressi­ble, de préférence un mélange aqueux contenant un bactéricide, un antifongique ou analogue. Ce fluide est introduit après achève­ment de la semelle par un orifice 20 réalisé dans le bourrelet 2 et débouchant dans la chambre formée par la fenêtre 8. Cet orifi­ce 20 est ensuite fermé par un bouchon 21.Two thin sheets 17 and 18, respectively for the upper surface and the lower surface, are placed above the strips 11-15 and welded on their periphery on the faces 6 of the peripheral edge 2. As regards the upper thin sheet 17 , this is welded only on the curved surface 19 remaining at the periphery of the chamfer 5 and the weld bead which is likely to occur along the edges of the weld zones is confined in the angle between said chamfer 5 and the thin sheet 17. It therefore does not reduce the active surface of the upper face of the sole which, with the specific shape of the strips 11, is located at the edges of the edges of the parts 13 of the strips. The surfaces 6 on which the thin sheets 17 and 18 are joined by heat welding with the bead 2, being curved, the pressure which is created in the center of the weld strip is higher than along the edges of the strip because the compressibility of the material constituting the bead 2 and we ob thus holds a more resistant and more waterproof weld. The entire volume between the two sheets and the peripheral edge 2 is filled with a compressible or incompressible fluid, preferably an aqueous mixture containing a bactericide, an antifungal or the like. This fluid is introduced after completion of the sole by an orifice 20 produced in the bead 2 and opening into the chamber formed by the window 8. This orifice 20 is then closed by a plug 21.

Lorsque la semelle est appliquée sous pression sur le sol par sa surface inférieure constituée par la feuille 18, les lamelles 15 sont écrasées et le fluide sous pression se trouvant entre deux la­melles est châssé vers la chambre située plus vers l'avant et ain­si de proche en proche jusqu'à la fenêtre 7 où il passe dans la chambre de la surface supérieure. Les parties de la chambre supé­rieure situées au droit du talon et de la zone métatarsienne sont comprimées et le liquide qui y est enfermé entre les lamelles 11 est, du fait de l'inclinaison des lamelles, châssé vers la partie arrière de la semelle, les lamelles 11 interdisant son refoule­ment vers l'avant. Par contre le liquide passe entre les arêtes des lamelles 11 situées vers l'arrière par rapport à la zone de pression et la feuille mince supérieure 17 qui ferme la cavité su­périeure de la semelle, en fléchissant la partie 13 des lamelles 11 vers l'arrière, les voiles 14 s'opposant au passage du liquide le long du bord 2 tout en laissant à la partie 13 une possibilité de fléchissement élevée du fait de leur propre minceur. Ceci assu­re une circulation intense du liquide, cette circulation étant, avec les caractéristiques ci-dessus décrites des lamelles 11, con­ centrée dans la zone centrale de la semelle au droit des arêtes des parties épaisses 13 des lamelles 11.When the sole is applied under pressure to the ground by its lower surface formed by the sheet 18, the strips 15 are crushed and the pressurized fluid located between two strips is driven towards the chamber located more forward and thus close close to window 7 where it goes into the upper surface chamber. The parts of the upper chamber situated to the right of the heel and of the metatarsal zone are compressed and the liquid which is enclosed therein between the lamellae 11 is, due to the inclination of the lamellae, driven towards the rear part of the sole, the slats 11 preventing it from being pushed forward. On the other hand, the liquid passes between the edges of the lamellae 11 situated towards the rear relative to the pressure zone and the upper thin sheet 17 which closes the upper cavity of the sole, by bending the part 13 of the lamellae 11 towards the rear. , the webs 14 opposing the passage of the liquid along the edge 2 while leaving the part 13 a possibility of high deflection due to their own thinness. This ensures an intense circulation of the liquid, this circulation being, with the characteristics described above of the strips 11, con centered in the central zone of the sole in line with the edges of the thick parts 13 of the strips 11.

Pour améliorer encore plus le fonctionnement de la semelle, il est possible d'empêcher la circulation du fluide à contre-courant en réalisant, dans les fenêtres 7 et 8, des soupapes anti-retour tel­les que la lamelle 22 qui obture la fenêtre 8 en s'appuyant sur la face inférieure des barrettes 10 et le bord du corps 1 pour s'oppo­ser à la remontée du fluide de la chambre inférieure vers la cham­bre supérieure.To further improve the functioning of the sole, it is possible to prevent the circulation of the fluid against the current by making, in windows 7 and 8, non-return valves such as the lamella 22 which closes the window 8 in pressing on the underside of the bars 10 and the edge of the body 1 to oppose the rise of the fluid from the lower chamber to the upper chamber.
