Description

La présente invention concerne un semelage pour chaussures diverses, de ville, de sport, d'appartement, de sécurité ou autres, permettant de masser le pied.The present invention relates to a sole assembly for various shoes, city, sports, apartment, security or other, for massaging the foot.

Les brevets français n° 1.407.004 et n° 2.095.495 décrivent des semelles notamment pour sandales dont le dessus présente des saillies, tels que des picots en matière souple, sur lesquelles la plante du pied repose.French patents No. 1,407,004 and No. 2,095,495 describe soles, in particular for sandals, the upper of which has projections, such as studs made of flexible material, on which the sole of the foot rests.

Les saillies sont destinées à exercer sur le pied une action thérapeutique correctrice et, concomitamment, un massage.The projections are intended to exert a corrective therapeutic action on the foot and, concomitantly, a massage.

Ce massage est destiné à atténuer les douleurs plantaires, à activer la circulation sanguine et à renforcer les muscles.This massage is intended to reduce plantar pain, activate blood circulation and strengthen muscles.

En réalité, le résultat obtenu n'est pas aussi satisfaisant qu'il était permis de l'espérer. Cela semble dû au fait que le contact de chaque picot avec le pied est ponctuel et ne se déplace pratiquement pas lors de la marche sous la plante du pied. En outre, l'action des picots n'est pas permanente, du fait que les sandales ne sont pas destinées à être portées toute la journée, le pied reposant sur la semelle étant nu.In reality, the result obtained is not as satisfactory as it might have been hoped. This seems to be due to the fact that the contact of each spike with the foot is punctual and practically does not move when walking under the sole of the foot. In addition, the action of the pins is not permanent, because the sandals are not intended to be worn all day, the foot resting on the sole being bare.

D'autres inconvénients apparaissent lors d'un usage prolongé : échauffement plantaire, risque de maladies de peau, usure des picots...Other disadvantages appear during prolonged use: plantar heating, risk of skin diseases, wear of the pins ...

La présente invention a pour but essentiel de masser véritablement et efficacement le pied, alors qu'une chaussette est enfilée sur le pied et que les moyens mis en oeuvre sont incorporés dans une chaussure prévue pour être portée toute la journée.The main object of the present invention is to truly and effectively massage the foot, while a sock is slipped over the foot and the means used are incorporated in a shoe intended to be worn all day.

L'invention poursuivant ce but, réside en ce que des billes en matière souple à rappel élastique ferme sont logées dans au moins une cavité du semelage s'étendant sur une partie au moins de la longueur, les billes étant réparties en au moins une couche avec un jeu suffisant mais limité pour qu'elles puissent rouler sur une faible distance et en ce que la première recouvrant la cavité est relativement souple afin que les billes en se déformant et en roulant massent le pied à travers la première.The invention pursuing this aim resides in that balls made of flexible material with firm elastic return are housed in at least one sole cavity extending over at least part of the length, the balls being distributed in at least one layer with sufficient but limited play so that they can roll over a short distance and in that the first covering the cavity is relatively flexible so that the balls, deforming and rolling, massage the foot through the first.

Les billes ont un coefficient d'adhérence tel qu'elles roulent sans glisser.The balls have an adhesion coefficient such that they roll without slipping.

En particulier, les billes peuvent être constituées par un polymère de base styrène-butadiène-styrène, modifié par des résines styréniques, des plastifiants, des charges et des agents de protection.In particular, the beads can be constituted by a styrene-butadiene-styrene base polymer, modified by styrene resins, plasticizers, fillers and protective agents.

Suivant une forme de réalisation avantageuse, les billes sont indépendantes avant leur mise en place dans la ou les cavités.According to an advantageous embodiment, the balls are independent before they are placed in the cavity or cavities.

Suivant une autre forme de réalisation avantageuse, les billes restent réunies pour former au moins une grappe avant leur mise en place dans la ou les cavités, par les appendices remplissant les canaux qui relient les empreintes du moule, ces appendices étant amincis près des billes pour se casser lors de la première utilisation de la chaussure et libérer ainsi lesdites billes.According to another advantageous embodiment, the balls remain united to form at least one cluster before their placement in the cavity or cavities, by the appendages filling the channels which connect the mold cavities, these appendages being thinned near the balls to break during the first use of the shoe and thus release said balls.

Les billes peuvent être de même diamètre ou de diamètres différents.The balls can be of the same diameter or of different diameters.

Avantageusement, elles sont réparties en quinconce sur au moins deux couches au droit du talon et côte à côte sur une couche au droit de l'avant-pied.Advantageously, they are distributed in staggered rows over at least two layers in line with the heel and side by side over a layer in line with the forefoot.

Divers autres caractéristiques et avantages de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics and advantages of the invention will also emerge from the detailed description which follows.

Suivant une première forme de réalisation illustrée par Les figures 1 à 4, le semelage comporte une semelle d'usure 1 venue de moulage avec un entourage épais 2 délimitant une cavité 3. Cet entourage est indéformable sous la pression du pied. Il présente une portée supérieure 4 sensiblement horizontale sur laquelle est posée et fixée, après remplissage de la cavité 3 avec des billes 5, une première de montage 6 faisant corps avec une tige de chaussure 7.According to a first embodiment illustrated by FIGS. 1 to 4, the sole assembly includes a wear sole 1 molded with a thick surround 2 delimiting a cavity 3. This surround is undeformable under the pressure of the foot. It has a substantially horizontal upper surface 4 on which is placed and fixed, after filling of the cavity 3 with balls 5, a first mounting 6 being integral with a shoe upper 7.

Les billes 5 pour remplir leur fonction de massage sont constituées par une matière souple à rappel élastique ferme. Avantageusement, il peut s'agir d'un polymère de base styrène-butadiène-styrène. En particulier, ce polymère peut être modifié par des résines styréniques, des plastifiants, des charges, des agents de protection.The balls 5 to fulfill their massage function are made of a flexible material with firm elastic return. Advantageously, it may be a styrene-butadiene-styrene base polymer. In particular, this polymer can be modified by styrenic resins, plasticizers, fillers, protective agents.

Un tel produit est connu dans le commerce sous la marque MORVANFLEX et la référence CT 601. Ses caractéristiques sont une densité de 0,99, une dureté Shore A de 40/45, une résistance à la rupture de 64 DAN/cm2, et un allongement % de 800.Such a product is known commercially under the brand MORVANFLEX and the reference CT 601. Its characteristics are a density of 0.99, a Shore A hardness of 40/45, a breaking strength of 64 DAN / cm2, and a elongation% of 800.

Il convient pour la fabrication des billes 5 qui ont alors la souplesse élastique requise et qui ont en outre une adhérence telle qu'elles ne glissent pas mais peuvent rouler en raison de leur sphéricité.It is suitable for the manufacture of balls 5 which then have the required elastic flexibility and which also have an adhesion such that they do not slip but can roll due to their sphericity.

La première de montage 6 est relativement souple de façon qu'elle transmette en tous points aux billes 5 la pression que le pied applique sur elle lors des évolutions.The first mounting 6 is relatively flexible so that it transmits at all points to the balls 5 the pressure that the foot applies to it during changes.

Les billes doivent intervenir pour que les réactions aux chocs et vibrations inévitalement renvoyées au corps à travers la première ne soient pas désagréables et n'engendrent pas de fatigue, encore moins de traumatismes tels que des tendinites ; au contraire, ces réactions permettent de masser le pied en permanence en apportant une sensation de bien-être. A cet effet, lesdites billes 5 ne sont pas jointives, mais disposées avec un léger jeu de sorte qu'elles peuvent s'écraser et se déplacer légèrement en roulant.The balls must intervene so that the reactions to shocks and vibrations inevitably returned to the body through the first are not unpleasant and do not generate fatigue, even less trauma such as tendinitis; on the contrary, these reactions make it possible to massage the foot permanently while bringing a feeling of well-being. To this end, said balls 5 are not contiguous, but arranged with a slight clearance so that they can crush and move slightly while rolling.

Dans cette première forme de réalisation (figures 1 à 4), les billes 5 sont indépendantes les unes des autres avant leur mise en place dans la cavité 3. Elles sont identiques entre elles et présentent le même diamètre. Elles sont réparties en quinconce suivant deux couches 8, 9 (figures 1 et 3 ) au droit du talon et côte à côte (figures 1 et 4) suivant une couche 10 au droit de l'avant-pied ; au droit de la cambrure, les deux couches s'interpénètrent progressivement.In this first embodiment (FIGS. 1 to 4), the balls 5 are independent of each other before they are placed in the cavity 3. They are identical to each other and have the same diameter. They are distributed in staggered rows in two layers 8, 9 (Figures 1 and 3) to the right of the heel and side by side (Figures 1 and 4) in a layer 10 to the right of the forefoot; at the level of the arch, the two layers gradually interpenetrate.

Suivant une deuxième forme de réalisation illustrée par la figure 7, le semelage comporte un talon 30 relativement haut et la semelle 1 présente en saillie vers le haut des nervures transversales 31 et des nervures longitudinales 32 délimitant entre elles des cavités d'allègement 33 s'étendant de la cambrure à l'arrière du talon.According to a second embodiment illustrated by FIG. 7, the sole assembly comprises a relatively high heel 30 and the sole 1 projecting upwards from the transverse ribs 31 and the longitudinal ribs 32 delimiting between them relief cavities 33 s' extending from the camber to the back of the heel.

Etant donné que la cavité 3 s'étend sur toute la longueur du semelage, une plaquette 34 repose sur les nervures 31 et 32 et constitue le fond de ladite cavité à l'arrière. Comme le montre la figure 7, les billes 5 sont réparties suivant une couche unique 10 d'un bout à l'autre du semelage et sont recouvertes par la première de montage 6.Since the cavity 3 extends over the entire length of the sole assembly, a plate 34 rests on the ribs 31 and 32 and constitutes the bottom of said cavity at the rear. As shown in FIG. 7, the balls 5 are distributed in a single layer 10 from one end to the other of the sole assembly and are covered by the first mounting 6.

Dans la troisième forme de réalisation illustrée par la figure 8, le semelage est semblable à celui de la figure 7, à la seule différence près que la première de montage 6 repose sur les nervures 31 et 32 à l'endroit du talon. Dès lors, la cavité 3 est limitée à l'avant-pied et contient une couche unique de billes 5.In the third embodiment illustrated in FIG. 8, the sole assembly is similar to that of FIG. 7, with the only difference that the first mounting 6 rests on the ribs 31 and 32 at the heel. Consequently, the cavity 3 is limited to the forefoot and contains a single layer of balls 5.

Suivant la quatrième forme de réalisation illustrée par la figure 9, le semelage est celui d'une chaussure de femme à talon 35. La semelle 1 délimite à l'avant-pied une cavité 3 contenant une couche unique de billes 5, cette cavité s'arrêtant à la partie cambrée de la semelle qui rejoint le talon 35 et délimite un creux 36.According to the fourth embodiment illustrated by FIG. 9, the sole assembly is that of a woman's shoe with heel 35. The sole 1 delimits at the forefoot a cavity 3 containing a single layer of balls 5, this cavity s 'stopping at the arched part of the sole which joins the heel 35 and delimits a hollow 36.

Quelle que soit la forme de réalisation choisie et ainsi que cela ressort de la figure 5 se rattachant, à titre d'exemple, à la première forme de réalisation selon la figure 1, les billes 5 relativement grosses peuvent coopérer avec de petites billes 11, voire avec des billes moyennes non représentées.Whatever the embodiment chosen and as can be seen from FIG. 5 relating, for example, to the first embodiment according to FIG. 1, the relatively large balls 5 can cooperate with small balls 11, even with medium balls not shown.

Il peut s'agir d'un mélange conduisant à une répartition aléatoire dont le modèle se modifie au gré du mouvement du pied.It can be a mixture leading to a random distribution, the model of which changes with the movement of the foot.

Il semble cependant plus avantageux de répartir les petites billes 11 suivant une couche intermédiaire 12 s'intercalant en quinconce entre les couches sus-jacente 8 et sous-jacente 9 de grosses billes (figure 5).However, it seems more advantageous to distribute the small balls 11 along an intermediate layer 12 which is staggered between the overlying layers 8 and the underlying layers 9 of large balls (FIG. 5).

Selon une autre variante illustrée par la figure 6, une plaque intercalaire 13 relativement souple peut être disposée entre les couches 8 et 9. Cette plaque peut présenter des alvéoles 14 dont l'étendue est telle que les billes qui s'y trouvent logées peuvent non seulement s'écraser, mais également rouler.According to another variant illustrated in FIG. 6, a relatively flexible intermediate plate 13 can be placed between the layers 8 and 9. This plate can have cells 14 whose extent is such that the balls which are housed therein can not not only crash, but also roll.

Bien entendu, il ne faut pas que les billes 5 se trouvant dans la partie en forme de coin de la cavité 3 au droit de la cambrure, s'accumulent, se coincent mutuellement et soulèvent la première en la déformant.Of course, the balls 5 located in the wedge-shaped part of the cavity 3 at the right of the camber must not accumulate, become mutually jammed and lift the first by deforming it.

A cet effet, la première de montage 6 qui dans l'ensemble est souple peut être raidie sur une partie de son étendue. En particulier et ainsi que cela ressort de la figure 8, des nervures longitudinales 15 peuvent être formées sous la première 6. Le raidissement est obtenu par l'accroissement de l'épaisseur de la matière souple. Si la raideur doit être plus accentuée, les nervures 15 sont réalisées en une matière plus dure et sont fixées sous la première par collage, soudage ou autre. Les nervures sont avantageusement conformées en gouttières (figure 8) pour bien guider les billes et empêcher leur accumulation.To this end, the first mounting 6 which on the whole is flexible can be stiffened over part of its extent. In particular and as is apparent from FIG. 8, longitudinal ribs 15 can be formed under the first 6. The stiffening is obtained by increasing the thickness of the flexible material. If the stiffness must be increased, the ribs 15 are made of a harder material and are fixed under the first by gluing, welding or other. The ribs are advantageously shaped into gutters (Figure 8) to properly guide the balls and prevent their accumulation.

Dans les formes de réalisation précitées (figures 1 à 4, 7 à 9) les billes 5, 11 sont placées dans la cavité 3 avec ou sans plaque intercalaire 13 et la première de montage 6 faisant corps avec la tige 7 par collage, piquage ou autre, est posée sur la portée supérieure 4 de l'entourage 2, puis y est fixée par tout moyen approprié : collage, soudage ...In the aforementioned embodiments (FIGS. 1 to 4, 7 to 9) the balls 5, 11 are placed in the cavity 3 with or without intermediate plate 13 and the first mounting 6 is integral with the rod 7 by gluing, stitching or other, is placed on the upper surface 4 of the surround 2, then is fixed there by any appropriate means: bonding, welding ...

Dans l'exemple choisi (figures 1 et 2), la cavité 3 s'étend sur toute la longueur du semelage et est unique.In the example chosen (Figures 1 and 2), the cavity 3 extends over the entire length of the sole assembly and is unique.

Cependant, selon une variante illustrée par la figure 10, il peut être avantageux de prévoir plusieurs cavités 16 séparées les unes des autres par des cloisons transversales 17 reliant les côtés longitudinaux de l'entourage 2 et faisant saillie sur la semelle d'usure 1 jusqu'à un niveau inférieur à celui de la portée supérieure 4 dudit entourage.However, according to a variant illustrated in Figure 10, it may be advantageous to provide several cavities 16 separated from each other by transverse partitions 17 connecting the longitudinal sides of the surround 2 and projecting on the outsole 1 up to 'at a level lower than that of the upper range 4 of said entourage.

Que le semelage comporte une seule cavité s'étendant sur une partie au moins de son étendue ou qu'il en comporte plusieurs, les flancs 18 de ces cavités peuvent avantageusement être pentus et converger vers le haut afin de mieux contenir les billes au remplissage et lorsqu'elles sont sollicitées par le pied.Whether the sole assembly has a single cavity extending over at least part of its extent or whether it comprises several, the sides 18 of these cavities can advantageously be sloping and converge upward in order to better contain the balls when filling and when they are stressed by the foot.

Dans les formes de réalisation décrites dans ce qui précède, les billes 5, 11 sont indépendantes les unes des autres avant leur mise en place dans la cavité 3 ou les cavités 16.In the embodiments described in the foregoing, the balls 5, 11 are independent of each other before they are placed in the cavity 3 or the cavities 16.

Mais il peut être avantageux, en particulier pour faciliter le remplissage et le rendre plus rapide, de mettre en oeuvre l'autre mode d'exécution illustré par les figures 12 et 13.However, it may be advantageous, in particular to facilitate filling and make it faster, to use the other embodiment illustrated in FIGS. 12 and 13.

Suivant cet autre mode d'exécution, les billes 5 ou 5 et 11 restent réunies, avant leur mise en place dans la ou les cavités 3, 16, par les appendices 19 qui remplissent après injection les canaux reliant les empreintes du moule, les billes ainsi réunies formant une grappe 20. Il est intéressant de remarquer que près des billes, les appendices 19 sont amincis. Grâce à cette particularité, la grappe de billes peut être mise en place dans la ou les cavités comme une pièce monolithique dont aucun élément ne peut se détacher lors de la fabrication de la chaussure ; par contre, lors de la première utilisation au moins de cette chaussure, les appendices 19 se rompent au ras des billes de sorte que ces billes deviennent libres et se comportent comme indiqué dans ce qui précède, indépendamment les unes des autres.According to this other embodiment, the balls 5 or 5 and 11 remain united, before their installation in the cavity or cavities 3, 16, by the appendages 19 which fill after injection the channels connecting the mold cavities, the balls thus united forming a cluster 20. It is interesting to note that near the balls, the appendages 19 are thinned. Thanks to this feature, the cluster of beads can be place in the cavity or cavities as a monolithic piece from which no element can be detached during the manufacture of the shoe; on the other hand, during at least the first use of this shoe, the appendages 19 break flush with the balls so that these balls become free and behave as indicated in the above, independently of each other.

Lorsque les billes sont regroupées en grappe, la grappe peut être déposée dans la ou les cavités 3, 16 du semelage selon la figure 1, avant que la première 6 montée sur la tige 7 soit fixée par tout moyen approprié sur la portée 4 dudit semelage.When the balls are grouped in a cluster, the cluster can be deposited in the cavity or cavities 3, 16 of the sole assembly according to FIG. 1, before the first 6 mounted on the rod 7 is fixed by any appropriate means to the bearing surface 4 of said sole assembly .

De la même manière, lorsque le semelage 1, 2 est injecté sur la tige 7, des remontées 21 de ce semelage recouvrant le bas de cette tige (figure 16) la ou les cavités 3, 16 dudit semelage sont accessibles par le haut à travers ladite tige pour recevoir des billes indépendantes 5, 11 ou une grappe 20 de telles billes. La première de propreté 22 qui dans ce cas possède une certaine tenue malgré sa souplesse, est alors posée et collée sur la portée 4 du semelage.In the same way, when the sole assembly 1, 2 is injected onto the rod 7, lifts 21 of this sole assembly covering the bottom of this rod (FIG. 16) the cavity or cavities 3, 16 of said sole assembly are accessible from above through said rod for receiving independent balls 5, 11 or a cluster 20 of such balls. The first cleanliness 22 which in this case has a certain resistance despite its flexibility, is then placed and glued to the bearing surface 4 of the sole assembly.

D'autres modes d'exécution illustrés par les figures 14 et 15 peuvent être mis en oeuvre pour faciliter le remplissage de la cavité 3 avec des billes indépendantes 5, 11 lorsque la première 6 montée sur la tige 7 est fixée.Other embodiments illustrated in Figures 14 and 15 can be implemented to facilitate filling of the cavity 3 with independent balls 5, 11 when the first 6 mounted on the rod 7 is fixed.

L'entourage 2 (figure 14) peut présenter au moins un orifice postérieur 23 à travers lequel les billes peuvent être introduites. Après remplissage correct, l'orifice 23 est fermé au moyen d'un bouchon 24.The surround 2 (FIG. 14) may have at least one rear orifice 23 through which the balls can be introduced. After correct filling, the orifice 23 is closed by means of a plug 24.

La première 6 (figure 15) peut présenter une ouverture 25 à travers laquelle les billes ou des grappes convenablement fractionnées sont introduites. Après remplissage, l'ouverture 25 est recouverte par une talonnette souple de finition 26.The first 6 (FIG. 15) may have an opening 25 through which the balls or suitably divided clusters are introduced. After filling, the opening 25 is covered by a flexible finishing heel 26.
