Description

La présente invention concerne une semelle ventilée d'article chaussant et son procédé de fabrication, ainsi que l'article chaussant obtenu intégrant une telle semelle.The present invention relates to a ventilated footwear sole and its manufacturing method, and the footwear obtained incorporating such a sole.

Elle concerne plus particulièrement une semelle comprenant une couche d'usure et une couche de confort positionnée à recouvrement au moins partiel de la couche d'usure, ladite couche d'usure présentant, au niveau du talon de la semelle, en position de contact d'appui au sol du talon, une zone déformable dans le sens d'un rapprochement de la couche de confort sous l'effet d'une charge exercée sur ladite couche de confort, à la verticale dudit talon.It relates more particularly to a soleplate comprising a wear layer and a comfort layer positioned at least partially covering the wear layer, said wear layer having, at the heel of the sole, in the contact position of heel ground support, a deformable zone in the direction of bringing the comfort layer closer under the effect of a load exerted on said comfort layer, at the vertical of said heel.

Des semelles ventilées permettant une circulation d'air à l'intérieur de l'article chaussant sont connues de l'état de la technique, comme l'illustrent la demande de brevet EP 0 714 611 ou de la demande internationale WO 2012/126489 . Toutefois, jusqu'à présent, la réalisation de telles semelles est complexe. Elle nécessite, en particulier dans le cas de la demande internationale précitée, la présence d'un insert fermé et/ou une valve.Ventilated soles allowing air circulation inside the article of footwear are known from the state of the art, as illustrated by the patent application. EP 0 714 611 or the international application WO 2012/126489 . However, until now, the realization of such soles is complex. It requires, especially in the case of the aforementioned international application, the presence of a closed insert and / or a valve.

Un but de la présente invention est donc de proposer une semelle du type précité, de conception simplifiée.An object of the present invention is therefore to provide a sole of the aforementioned type, simplified design.

Un autre but de la présente invention est de proposer une semelle du type précité dont la conception permet de s'affranchir de clapet, de membrane, ou de valve rapportée.Another object of the present invention is to provide a sole of the aforementioned type whose design eliminates valve, membrane, or valve reported.

À cet effet, l'invention a pour objet une semelle d'article chaussant, ladite semelle comprenant une couche d'usure, une couche de confort positionnée à recouvrement au moins partiel de la couche d'usure, et un insert, interposé entre lesdites couches d'usure et de confort, ladite couche d'usure présentant, au niveau du talon de la semelle, en position de contact d'appui au sol du talon, une zone déformable dans le sens d'un rapprochement de la couche de confort sous l'effet d'une charge exercée sur ladite couche de confort à la verticale dudit talon,
caractérisée en ce que l'insert, noyé partiellement dans la matière constitutive de la couche de confort, est une pièce préfabriquée affectant la forme d'un couvercle comprenant un fond et un rebord, cet insert à concavité tournée vers la couche d'usure et délimitant, au niveau du talon de la semelle, avec au moins une partie de la zone de la couche d'usure déformable sous charge en position de contact d'appui au sol du talon, une chambre de réserve d'air, compressible, en communication avec l'extérieur par au moins un canal traversant la couche de confort, le fond de l'insert, écarté de la couche d'usure étant, à l'état assemblé des couches d'usure et de confort muni d'un trou qui forme le débouché du canal traversant la couche de confort dans ladite chambre de réserve d'air.For this purpose, the subject of the invention is a footwear sole, said sole comprising a wear layer, a comfort layer positioned at least partially covering the wear layer, and an insert, interposed. between said wear and comfort layers, said wear layer having, at the level of the heel of the sole, in a position of contact with the ground of the heel, a deformable zone in the direction of approaching the layer of comfort under the effect of a load exerted on said comfort layer at the vertical of said heel,
characterized in that the insert, partially embedded in the material constituting the comfort layer, is a prefabricated piece having the shape of a lid comprising a bottom and a flange, this concavity insert facing towards the wear layer and delimiting, at the level of the heel of the soleplate, with at least a portion of the region of the wear-deformable wear layer in the position of bearing contact with the ground of the heel, a compressible air reserve chamber, in communication with the outside by at least one channel passing through the comfort layer, the bottom of the insert, separated from the wear layer being, in the assembled state, wearing and comfort layers provided with a hole which forms the outlet of the channel passing through the comfort layer in said air reserve chamber.

Grâce au fait que l'insert délimite, au niveau du talon de la semelle, en coopération avec au moins une partie de la zone de la couche d'usure déformable sous charge en position de contact d'appui au sol du talon, une chambre de réserve d'air, on obtient une chambre d'air compressible par la pression du talon et revenant à sa position d'origine par la libération de la pression du talon.Due to the fact that the insert defines, at the heel of the soleplate, in cooperation with at least a portion of the region of the wear-deformable wear layer in the heel contact position with the ground of the heel, a chamber of air reserve, one obtains an air chamber compressible by the pressure of the heel and returning to its original position by releasing the pressure of the heel.

Les parties de la zone de la couche d'usure participant à la délimitation de la chambre forment ainsi une paroi de ladite chambre, sans nécessiter de rapporter des éléments supplémentaires.The portions of the zone of the wear layer participating in the delimitation of the chamber thus form a wall of said chamber, without the need to report additional elements.

La conception de l'insert sous forme d'un couvercle et sa disposition à l'intérieur de la semelle permettent d'éviter un fluage de matière à l'intérieur de l'insert en dépit d'un insert ouvert, associé à une technique de surmoulage de la couche de confort sur la couche d'usure.The design of the insert in the form of a lid and its arrangement inside the soleplate make it possible to avoid a creep of material inside the insert despite an open insert associated with a technique overmoulding of the comfort layer on the wear layer.

De préférence, l'insert est fixé à la couche d'usure par un montage à emboitement. Il en résulte un positionnement sûr de l'insert, une fois noyé dans la matière constitutive de la couche de confort.Preferably, the insert is attached to the wear layer by a fitting fitting. This results in a safe positioning of the insert, once embedded in the constituent material of the comfort layer.

De préférence, l'insert est maintenu à l'état emboité à la couche d'usure par la matière constitutive de la couche de confort. Il en résulte une simplicité de la semelle.Preferably, the insert is maintained in the nested state to the wear layer by the material constituting the comfort layer. This results in a simplicity of the sole.

Grâce au fait que l'insert est une pièce préfabriquée affectant la forme d'un couvercle comprenant un fond et un rebord de préférence bordé d'une aile périphérique, l'insert peut ainsi être simplement posé sur la face supérieure de la couche d'usure, au niveau de la zone déformable sous charge de ladite couche d'usure, pour former en coopération avec ladite zone déformable une chambre. L'insert repose aussi simplement par le bord libre de son rebord sur la face supérieure de la couche d'usure.Due to the fact that the insert is a prefabricated piece having the shape of a lid comprising a bottom and a flange preferably bordered by a peripheral flange, the insert can thus be simply placed on the upper face of the layer of wear, at the level of the deformable zone under load of said wear layer, to form a chamber in cooperation with said deformable zone. The insert also rests simply by the free edge of its flange on the upper face of the wear layer.

De préférence, l'insert est une pièce de rigidité supérieure à celle des couches d'usure ou de confort.Preferably, the insert is a piece of stiffness greater than that of wear or comfort layers.

De préférence, la face dite supérieure de la couche d'usure opposée à celle d'appui au sol est munie d'une cavité annulaire à l'intérieur de laquelle ledit insert est, par l'intermédiaire au moins de son rebord, apte à s'emboiter partiellement.Preferably, the so-called upper face of the wear layer opposite to that of ground support is provided with an annular cavity inside which said insert is, via at least its rim, adapted to partially fit.

Généralement, l'insert est apte à s'emboîter partiellement dans la cavité annulaire par introduction au moins partielle du rebord de l'insert dans ladite cavité avec le bord libre du rebord, ou l'aile périphérique externe du rebord lorsque ladite aile est présente, apte à reposer sur le fond de la cavité.Generally, the insert is adapted to partially fit into the annular cavity by at least partial introduction of the flange of the insert into said cavity with the free edge of the flange, or the outer peripheral flange of the flange when said flange is present. , able to rest on the bottom of the cavity.

Cette configuration permet de limiter le risque de fluage de la matière de la couche de confort à l'intérieur de la chambre, au risque de perturber un fonctionnement ultérieur de ladite chambre.This configuration makes it possible to limit the risk of creep of the material of the comfort layer inside the chamber, with the risk of disturbing a subsequent operation of said chamber.

De préférence, la couche de confort est une couche surmoulée assemblée à la couche d'usure par moulage par injection.Preferably, the comfort layer is an overmolded layer assembled to the wear layer by injection molding.

De préférence, la couche de confort est munie, sur sa face supérieure opposée à sa face inférieure de liaison à la couche d'usure, d'un réseau de canaux de circulation d'air en communication avec le débouché du canal traversant de la couche de confort.Preferably, the comfort layer is provided, on its upper face opposite to its lower face of connection to the wear layer, with a network of air circulation channels in communication with the outlet of the channel passing through the layer. of comfort.

Ce réseau permet de répartir l'air issu de la chambre à la surface de la couche de confort, et d'assurer ainsi une ventilation ou une circulation d'air à l'intérieur de l'article chaussant formé à l'aide d'une telle semelle.This network distributes the air from the chamber to the surface of the comfort layer, and thus ensure ventilation or air circulation inside the article of footwear formed with the aid of such a sole.

De préférence, la zone de la couche d'usure, déformable dans le sens d'un rapprochement de la couche de confort sous l'effet d'une charge exercée sur ladite couche de confort à la verticale dudit talon en position de contact d'appui au sol du talon, est formée par une proéminence de la couche d'usure au niveau du talon de la semelle formant une surélévation de ladite semelle. Du fait de la souplesse de la couche d'usure, cette proéminence tend à s'écraser sous charge.Preferably, the zone of the wear layer, deformable in the direction of a coming of the comfort layer under the effect of a load exerted on said comfort layer vertically of said heel in the contact position of support on the heel floor, is formed by a prominence of the wear layer at the heel of the sole forming an elevation of said sole. Due to the flexibility of the wear layer, this prominence tends to crush under load.

De préférence, ladite semelle comprend une première de propreté venant à recouvrement de la couche de confort, cette première de propreté étant munie d'alvéoles et/ou de perforations.Preferably, said sole comprises a first cleanliness overlapping the comfort layer, this inseam being provided with cells and / or perforations.

Les figures illustrent l'application de l'invention à un article 13 chaussant comprenant une tige 14 pré-équipée d'une première 15 de montage et une semelle 1 du type de celle décrite ci-dessous.The figures illustrate the application of the invention to an article 13 footwear comprising a rod 14 pre-equipped with a first mounting 15 and a sole 1 of the type described below.

Cette semelle 1 comprend une couche d'usure 2, réalisée ici sous forme d'une couche translucide en thermo-polyuréthane. Cette couche d'usure 2 présente une face 21 inférieure d'appui au sol de la semelle et une face 22 supérieure de liaison au reste de la semelle. Cette couche d'usure 2 est surmontée d'une couche de confort 3. Dans l'exemple représenté, cette couche de confort 3 est une couche en polyuréthane injecté.This sole 1 comprises a wear layer 2, made here in the form of a translucent layer of thermo-polyurethane. This wear layer 2 has a bottom surface 21 of support of the sole and an upper face 22 of connection to the rest of the sole. This wear layer 2 is surmounted by a comfort layer 3. In the example shown, this comfort layer 3 is an injected polyurethane layer.

Cette couche de confort 3 présente une face 31 inférieure par l'intermédiaire de laquelle la couche de confort 3 est assemblée à la couche d'usure, et une face 32 supérieure qui, dans l'exemple représenté, est revêtue d'une première de propreté 11.This comfort layer 3 has a lower face 31 through which the comfort layer 3 is assembled to the wear layer, and an upper face 32 which, in the example shown, is coated with a first layer. cleanliness 11.

Cette première de propreté 11, généralement montée amovible sur la couche de confort, est munie d'alvéoles 12 et/ou de perforations et se présente ici sous forme d'un multicouche comprenant une couche inférieure alvéolée et une couche supérieure perforée, en textile. La couche 3 de confort est quant à elle munie, sur sa face 32 supérieure opposée à sa face 31 inférieure de liaison à la couche d'usure 2, d'un réseau de canaux 10 de circulation d'air dont le rôle sera décrit ci-après.This inseam 11, generally removably mounted on the comfort layer, is provided with cells 12 and / or perforations and is here in the form of a multilayer comprising a honeycomb bottom layer and a perforated upper layer, textile. The layer 3 of comfort is provided, on its upper face 32 opposite to its lower face 31 of connection to the wear layer 2, a network of air circulation channels 10 whose role will be described ci -after.

Enfin, il doit être noté que la couche d'usure 2 peut être une couche continue ou discontinue, comme représentée aux figures. Dans ce cas, cette couche d'usure s'interrompt dans les parties surélevées par rapport au sol de la semelle. Dans cette zone d'interruption, la couche de confort 3 forme la partie du dessous de la semelle.Finally, it should be noted that the wear layer 2 may be a continuous or discontinuous layer as shown in the figures. In this case, this wear layer is interrupted in the raised portions relative to the ground of the sole. In this interruption zone, the comfort layer 3 forms the part of the underside of the sole.

Cette couche d'usure 2 présente encore, au niveau du talon 4 de la semelle, en position de contact d'appui au sol du talon 4, une zone 5 déformable dans le sens d'un rapprochement de la couche de confort 3 sous l'effet d'une charge exercée sur ladite couche de confort 3 à la verticale dudit talon 4.This wear layer 2 still has, at the level of the heel 4 of the sole, in the ground contact position of the heel 4, a deformable zone 5 in the direction of bringing the comfort layer 3 closer together. effect of a load exerted on said comfort layer 3 at the vertical of said heel 4.

Dans l'exemple représenté, la zone 5 de la couche d'usure 2, déformable dans le sens d'un rapprochement de la couche de confort 3 sous l'effet d'une charge exercée sur ladite couche de confort 3 à la verticale dudit talon 4 en position de contact d'appui au sol du talon 4, est formée par une proéminence de la couche d'usure au niveau du talon de la semelle formant une surélévation de ladite semelle 1.In the example shown, the zone 5 of the wear layer 2, deformable in the direction of a bringing together of the comfort layer 3 under the effect of a load exerted on said comfort layer 3 in the vertical of said heel 4 in position of contact with the heel 4 of the ground support, is formed by a protrusion of the wear layer at the heel of the sole forming an elevation of said sole 1.

La semelle 1 comprend encore un insert 6 interposé entre lesdites couches d'usure 2 et de confort 3 et noyé partiellement dans la matière constitutive de la couche de confort 3 qui le masque depuis l'extérieur. Cet insert 6 délimite, au niveau du talon 4 de la semelle, avec au moins une partie de la zone 5 de la couche d'usure 2 déformable sous charge en position de contact d'appui au sol du talon 4, une chambre 7 de réserve d'air, compressible, en communication avec l'extérieur par un canal 8 traversant la couche de confort 3.The sole 1 further comprises an insert 6 interposed between said wear layers 2 and comfort 3 and partially embedded in the material constituting the comfort layer 3 which masks it from the outside. This insert 6 delimits, at the level of the heel 4 of the sole, with at least a part of the zone 5 of the deformable wear layer 2 under load in the ground contact position of the heel 4, a chamber 7 of air reserve, compressible, in communication with the outside via a channel 8 passing through the comfort layer 3.

Dans l'exemple représenté, cet insert 6 est une pièce préfabriquée, en matière thermoplastique, en particulier en ABS. Cet insert 6, de rigidité supérieure à celle des couches d'usure et de confort, affecte la forme d'un couvercle comprenant un fond 61 et un rebord 62 bordé d'une aile 63 périphérique externe. Le fond 61 est écarté de la couche d'usure 2. Le couvercle est orienté avec son creux tourné vers la couche d'usure 2. Le couvercle repose ainsi sur la couche d'usure 2 non pas par son fond mais via son rebord 62.In the example shown, this insert 6 is a prefabricated part, made of thermoplastic material, in particular ABS. This insert 6, of greater rigidity than that of the wear and comfort layers, has the shape of a lid comprising a bottom 61 and a flange 62 flanked by an outer peripheral flange 63. The bottom 61 is spaced from the wear layer 2. The cover is oriented with its hollow facing the wear layer 2. The cover thus rests on the wear layer 2 not by its bottom but via its rim 62 .

La face 22 dite supérieure de la couche d'usure 2 est quant à elle munie d'une cavité 9 annulaire à l'intérieur de laquelle ledit insert 6 est apte à s'emboîter partiellement par son rebord 62. Cette cavité 9 annulaire se présente ici sous forme d'une rainure annulaire ménagée, côté face 22 supérieure de la couche d'usure 2, autour de la zone 5 déformable de ladite couche d'usure 2.The upper face 22 of the wear layer 2 is provided with an annular cavity 9 inside which said insert 6 is adapted to fit together. partially by its flange 62. This annular cavity 9 is here in the form of an annular groove formed on the upper face 22 of the wear layer 2 around the deformable zone 5 of said wear layer 2.

Cette rainure, représentée ici circulaire, est délimitée par deux parois parallèles formant chacune un mur d'enceinte. Dans l'exemple représenté, la rainure étant circulaire, les deux parois sont coaxiales et appelées, l'une paroi périphérique externe, l'autre paroi périphérique interne de la rainure.This groove, represented here circular, is delimited by two parallel walls each forming a wall. In the example shown, the groove being circular, the two walls are coaxial and called, the one outer peripheral wall, the other inner peripheral wall of the groove.

Le rebord 62 de l'insert 6 est bordé d'une aile 63 périphérique. L'aile 63 périphérique externe de l'insert s'applique, par son bord libre, sur la face interne de la paroi périphérique externe de la rainure, tandis que le rebord de l'insert s'applique par sa face interne sur la face interne de la paroi périphérique interne de la rainure.The flange 62 of the insert 6 is bordered by a peripheral flange 63. The outer peripheral wing 63 of the insert is applied, by its free edge, to the inner face of the outer peripheral wall of the groove, while the edge of the insert is applied by its internal face to the face. internal wall of the inner peripheral wall of the groove.

Grâce à cette disposition, un risque de fluage de la matière constitutive de la couche de confort 3 à l'intérieur de la chambre formée par la coopération de l'insert et de la couche d'usure 2 est encore plus limité, voire écarté.Thanks to this arrangement, a risk of creep of the material constituting the comfort layer 3 inside the chamber formed by the cooperation of the insert and the wear layer 2 is even more limited or eliminated.

Le fond 61 de l'insert 6 est, à l'état assemblé des couches d'usure et de confort, muni d'un trou qui forme le débouché du canal 8 traversant la couche de confort dans ladite chambre 7 de réserve d'air. Ce trou et le canal 8 traversant la couche de confort sont ménagés par perçage de la couche de confort 3 et du fond du couvercle une fois la couche d'usure et de confort de la semelle assemblées l'une à l'autre.The bottom 61 of the insert 6 is, in the assembled state of wear and comfort layers, provided with a hole which forms the outlet of the channel 8 passing through the comfort layer in said air reserve chamber 7 . This hole and the channel 8 passing through the comfort layer are formed by piercing the comfort layer 3 and the bottom of the lid once the layer of wear and comfort of the sole assembled to one another.

Comme mentionné ci-dessus, cette chambre 7 de réserve d'air délimitée partiellement par la zone 5 déformable de la couche d'usure 2 est donc une chambre compressible, lors de la marche avec une telle semelle, à chaque appui au sol du talon de ladite semelle.As mentioned above, this air reserve chamber 7 partially delimited by the deformable zone 5 of the wear layer 2 is therefore a compressible chamber, when walking with such a sole, with each support of the heel of said sole.

L'air expulsé par déformation de la zone 5 déformable de la couche d'usure 2 hors de la chambre 7 de réserve d'air à travers le trou et le canal 8 traversant la couche de confort 3 est ensuite diffusé à l'intérieur de la chaussure, par le réseau de canaux de la face supérieure de la couche de confort 3.The air expelled by deforming the deformable zone 5 of the wear layer 2 out of the air reserve chamber 7 through the hole and through the channel 8 the comfort layer 3 is then diffused inside the shoe, by the channel network of the upper face of the comfort layer 3.

Pour la fabrication d'un tel article chaussant du type de celui décrit ci-dessus, on peut utiliser la technique de l'injecté direct. La tige est d'abord cousue, par exemple par une piqûre de type Ströbel, ou fixée par des moyens équivalents sur la première de montage en textile non tissé et mise sur forme par un opérateur sur un carrousel d'injection.For the manufacture of such an article of footwear of the type described above, it is possible to use the direct injected technique. The rod is first sewn, for example by a Ströbel-type puncture, or fixed by equivalent means on the first non-woven textile mounting and shaped by an operator on an injection carousel.

La couche d'usure de la semelle est ensuite déposée au fond du moule par coulée à l'aide d'un canon. La couche d'usure ayant durci, l'opérateur vient placer sur le dessus de ladite couche d'usure l'insert, créant ainsi la réserve d'air de la semelle. La tige sur forme est ensuite amenée au centre du moule à l'aide d'un bras articulé et des anneaux se referment sur la tige, pour former une cavité de moulage fermée. Le moule est alors prêt à recevoir la couche de confort 3, qui est injectée à l'aide d'un deuxième canon. La tige est alors soudée à la semelle par le fait de l'expansion à l'intérieur du moule du polyuréthane constitutif de la couche de confort qui se colle à la tige et au textile non tissé de la première de montage, notamment en traversant au moins partiellement la première de montage. Le canal de circulation d'air est ensuite percé à l'aide d'un foret traversant la couche de confort avant de déboucher dans la chambre, via le fond de l'insert.The wear layer of the sole is then deposited at the bottom of the mold by casting with a gun. With the wear layer having hardened, the operator places the insert on the top of the wear layer, thus creating the air reserve of the soleplate. The shaped rod is then brought to the center of the mold by means of an articulated arm and rings are closed on the rod to form a closed molding cavity. The mold is then ready to receive the comfort layer 3, which is injected with a second gun. The rod is then welded to the soleplate due to the expansion inside the mold of the polyurethane constitutive of the comfort layer which sticks to the rod and the nonwoven fabric of the first assembly, in particular through less partially the first of assembly. The air flow channel is then drilled with a drill through the comfort layer before opening into the chamber through the bottom of the insert.

L'article chaussant peut être finalisé, notamment par mise en place de la première de propreté.The article footwear can be finalized, including the establishment of the first cleanliness.
