The lid (2) is pierced in its centre to provide a leakproof passage for the shaft (31) of a beater (3), the head of the shaft (31) emerging to allow it to be driven in rotation. The lid (2) also has at least one connector (4) for attaching a connecting pipe between the flask (1) and a shoe to be treated. The shaft (31) of the beater (3) carries radial fins inclined to force the mixture towards the bottom (11), the latter rising along the wall of the flask (1). This wall advantageously has lengthwise projections (12) to increase the turbulence motions. The device permits a homogeneous mixing of the reactants to endow the stuffing with mechanical qualities which are uniform from one point to another. <IMAGE>

Description

La présente invention est relative à la confection d'un rembourrage anatomique souple entre la coque d'une chaussure et le pied du porteur, ce rembourrage étant réalisé chaussure au pied, donc personnalisé. Ce genre de rembourrage est recherché notamment pour des chaussures à coque rigide, très techniques, en particulier pour la pratique du ski.The present invention relates to the making of a flexible anatomical padding between the shell of a shoe and the wearer's foot, this padding being made shoe by foot, therefore personalized. This type of padding is sought in particular for shoes with rigid shell, very technical, in particular for the practice of skiing.

Selon la demande de brevet publiée sans examen DE 2 114 750, il est connu pour la réalisation d'un tel rembourrage d'introduire entre le pied du porteur et la coque de la chaussure, un mélange liquide de produits réagissant entre eux pour se solidifier en place par polymérisation assez rapide. On utilise de façon usuelle des isocyanates et des polyesters conduisant à une mousse de polyuréthane. Après mélange, le produit est introduit par gravité et par la pression des gaz engendrés au moyen d'un tube dans l'espace séparant la coque de la chaussure du pied du porteur.According to the patent application published without examination DE 2,114,750, it is known for the production of such padding to introduce between the wearer's foot and the shell of the shoe, a liquid mixture of products reacting with one another to solidify in place by fairly rapid polymerization. Isocyanates and polyesters are usually used, leading to a polyurethane foam. After mixing, the product is introduced by gravity and by the pressure of the gases generated by means of a tube into the space separating the shell of the shoe from the foot of the wearer.

Dans le brevet FR 2 111 147, on fait appel fondamentalement aux mêmes principes, mais pour éviter certains désagréments, notamment des salissures, le produit polymérisable préalablement mélangé est injecté dans une enveloppe, donc à paroi double dite "petit soulier" habillant le pied du porteur et formant après polymérisation un véritable chausson adapté tant à la coque de la chaussure qu'au pied du porteur.In patent FR 2 111 147, the same principles are used fundamentally, but to avoid certain inconveniences, in particular dirt, the polymerizable product previously mixed is injected into an envelope, therefore with a double wall called "small shoe" covering the foot of the foot. wearer and forming after polymerization a real liner suitable for both the shell of the shoe and the foot of the wearer.

Ces techniques évoquées présentent cependant de graves insuffisances pour ce qui concerne la préparation même du mélange poly­mérisable. On se contente, dans un flacon contenant le premier produit liquide, d'y verser le second également liquide, et de secouer manuelle­ment le premier flacon pour mélanger les produits avant de brancher le flacon sur un tube d'injection pour l'acheminement de la matière vers les espaces libres ou l'enveloppe séparant le pied du porteur de la coque de la chaussure.These techniques mentioned, however, have serious shortcomings with regard to the actual preparation of the polymerizable mixture. We simply, in a bottle containing the first liquid product, pour the second also liquid, and manually shake the first bottle to mix the products before connecting the bottle to an injection tube for the delivery of the material towards the free spaces or the envelope separating the foot of the wearer from the shell of the shoe.

Du fait de ce caractère purement manuel de la confection du mélange liquide polymérisable, celui-ci manque d'homogénéité suffisante et la réaction de polymérisation va se produire de façon relativement aléatoire selon les endroits du rembourrage en formation, en fonction des proportions respectives des constituants dans ces sites, et les qualités mécaniques attendues du rembourrage varieront d'un point à un autre et pourront en certains points ne pas correspondre du tout au résultat tech­nique qui était attendu.Due to this purely manual nature of the preparation of the liquid polymerizable mixture, it lacks sufficient homogeneity and the polymerization reaction will occur relatively randomly depending on the locations of the padding being formed, according to the respective proportions of the constituents. in these sites, and the mechanical qualities expected from the padding will vary from one point to another and may at certain points not correspond at all to the technical result which was expected.

Ces déficiences et insuffisances, selon la très rapide évolution, dans le domaine de la compétition notamment,ne sont plus compa­tibles avec les exigences des utilisateurs qui veulent un produit très performant, fiable, et ne présentant pas de variations aléatoires locales des qualités mécaniques, tout en n'en augmentant pas de façon prohibitive le prix de revient déjà relativement élevé.These deficiencies and inadequacies, according to the very rapid evolution, in the field of competition in particular, are no longer compatible with the requirements of users who want a high-performance, reliable product that does not have random local variations in mechanical qualities, while not prohibitively increasing them the cost price already relatively high.

La présente invention vise donc à surmonter les inconvénients ci-dessus pour donner à prix raisonnable satisfaction aux utilisateurs. Elle concerne un flacon mélangeur des produits de réaction devant assurer une homogénéité telle que les qualités mécaniques, notamment le confort éprouvé du rembourrage,ne soit pas sujette à des variations locales indé­sirables.The present invention therefore aims to overcome the above drawbacks to give reasonable satisfaction to users. It relates to a mixing bottle of reaction products which must ensure homogeneity such that the mechanical qualities, in particular the proven comfort of the padding, is not subject to undesirable local variations.

Les caractéristiques du flacon mélangeur selon l'invention et ses avantages par rapport à l'état connu de la technique apparaitront à la lumière de la description qui suit et pour l'intelligence de laquelle on se réfèrera aux dessins dont :

  • - la figure 1 montre en coupe axiale un flacon mélangeur conforme à la présente invention,
  • - la figure 2 représente l'enveloppe extérieure du flacon mélangeur de la figure 1, couvercle enlevé,
  • - la figure 3 est une vue de dessus dans un plan intermédiaire, tel que AA du flacon mélangeur de la figure 1 et illustrant son fonctionnement.
The characteristics of the mixing bottle according to the invention and its advantages over the known state of the art will appear in the light of the following description and for the understanding of which reference will be made to the drawings, of which:
  • FIG. 1 shows in axial section a mixing bottle in accordance with the present invention,
  • FIG. 2 represents the outer envelope of the mixing bottle of FIG. 1, cover removed,
  • - Figure 3 is a top view in an intermediate plane, such as AA of the mixing bottle of Figure 1 and illustrating its operation.

Comme illustré à la figure 1, le flacon mélangeur qui peut, dès l'origine, déjà contenir le produit liquide de base, se présente sous la forme générale d'un cyclindre circulaire droit constitué par une surface latérale 1 fermée en extrémité basse par un fond 11 venu d'une pièce avec la surface 1 et fermée également en partie supérieure par un couvercle 2 amovible étanche,rapporté, de préférence par vissage pour assurer cette étanchéité mieux que par emboîtement élastique par exemple. Le couvercle 2 est percé centralement pour permettre le passage de l'axe 31 d'un batteur 3 et latéralement, présente au moins un ajutage 4 en vue du branchement d'un tube pour l'écoulement du produit mélangé vers ses zones de polyméri­sation ultérieure. De préférence, deux ajutages 4, avantageusement diamétralement opposés, seront prévus pour permettre l'injection simultanée, et non à tour de rôle,du même mélange, et dans les mêmes conditions momen­tanées de site, pression, température,pour la réalisation du rembourrage dans les chaussures droite et gauche, ce qui est un avantage non négligeable de la présente invention.As illustrated in FIG. 1, the mixing bottle which can, from the outset, already contain the basic liquid product, is in the general form of a straight circular cyclinder constituted by a lateral surface 1 closed at the lower end by a bottom 11 coming in one piece with the surface 1 and also closed at the top by a removable waterproof cover 2, added, preferably by screwing to ensure this tightness better than by elastic interlocking for example. The cover 2 is pierced centrally to allow the passage of the axis 31 of a mixer 3 and laterally, has at least one nozzle 4 for the connection of a tube for the flow of the mixed product towards its zones of subsequent polymerization . Preferably, two nozzles 4, advantageously diametrically opposed, will be provided to allow the simultaneous injection, and not in turn, of the same mixture, and under the same momentary conditions of site, pressure, temperature, for the realization of the padding in right and left shoes, which is a significant advantage of the present invention.

L'axe 31 du batteur 3 est pourvu au-dessus de sa traversée étanche du couvercle 2 d'une tête 32 d'entrainement en rotation destinée à coopérer avec un outil motorisé portatif, par exemple du type perceuse. Avantageusement, cette tête 32 se présente sous la forme d'une tête de vis car l'outil d'entrainement en rotation le plus fréquemment utilisé par les monteurs dans les ateliers des magasins de sport est précisément le tournevis électrique. Cependant, cette tête 32 pourrait aussi bien avoir une forme carrée,ou ronde pour être serrée dans un mandrin.The axis 31 of the thresher 3 is provided above its sealed crossing of the cover 2 with a head 32 for rotational drive intended to cooperate with a portable power tool, for example of the drill type. Advantageously, this head 32 is in the form of a screw head because the rotary drive tool most frequently used by fitters in the workshops of sports shops is precisely the electric screwdriver. However, this head 32 could as well have a square shape, or round to be clamped in a mandrel.

L'axe 31 du batteur 3 traverse axialement l'intérieur du flacon mélangeur jusqu'au fond 11 au-dessus duquel il tourillonne sur une plaque de maintien 33. Cette plaque de maintien 33 garantit le maintien,en opé­ration,de l'axe 31 du batteur 3 en position centrée dans le flacon 1. En effet, à défaut d'un tel maintien, l'axe 31 en rotation aurait tendance à flotter ou fléchir et ses ailettes dont on va parler plus loin pourraient frotter ou frapper la paroi interne du flacon 1 et mettre le batteur 3 en vrille.The axis 31 of the beater 3 passes axially through the interior of the mixing bottle to the bottom 11 above which it pivots on a holding plate 33. This holding plate 33 guarantees the maintenance, in operation, of the axis 31 of the beater 3 in the centered position in the bottle 1. Indeed, in the absence of such a maintenance, the axis 31 in rotation would tend to float or bend and its fins which will be discussed later could rub or strike the internal wall from bottle 1 and spin the beater 3.

L'axe 31 est par ailleurs porteur sur deux côtés diamétra­lement opposés d'ailettes radiales 34 disposées sur plusieurs étages. Ces ailettes 34 de forme sensiblement plane et rectangulaire sont inclinées par rapport à la direction de l'axe 31 de manière à ce que, en rotation du batteur 3, elles forcent le fluide contenu dans le flacon mélangeur 1 vers le fond 11 tout en l'induisant en rotation autour de l'axe 31. Le fluide dans la partie centrale va donc être chassé vers le fond selon un mouvement approximativement hélicoïdal pour remonter ensuite le long de la paroi du flacon mélangeur 1. Les ailettes 34 d'un côté apparaissent donc d'inclinaison inversée par rapport à celles de l'autre côté mais se trouvent cependant exactement dans la même position après rotation d'un demi-tour de l'axe 31 du fait de la symétrie de révolution d'ordre deux.The axis 31 is also carrying on two diametrically opposite sides of radial fins 34 arranged on several stages. These fins 34 of substantially planar and rectangular shape are inclined relative to the direction of the axis 31 so that, in rotation of the mixer 3, they force the fluid contained in the mixing bottle 1 towards the bottom 11 while l 'inducing in rotation around the axis 31. The fluid in the central part will therefore be driven towards the bottom in an approximately helical movement to then rise up along the wall of the mixing bottle 1. The fins 34 on one side appear therefore of inverted inclination with respect to those on the other side but are however exactly in the same position after rotation of a half-turn of the axis 31 due to the symmetry of revolution of order two.

Pour accroitre l'efficacité du batteur 3 dans la réalisation d'un mélange parfaitement homogène, on cherche en outre à provoquer des turbulences ou remous le long de la paroi du flacon 1. Dans ce but, cette paroi est pourvue d'au moins deux saillies déflectrices longitudinales 12 s'étendant sur tout ou partie de la hauteur du flacon et laissant un jeu suffisant pour le passage des ailettes 34. Ces saillies déflectrices 12 freinent le courant tournant du fluide sur la paroi du flacon 1, ce qui assure un meilleur brassage. Pour une efficacité optimale, les saillies déflectrices 12, en forme de dent à section triangulaire, présentent avantageusement une pente plus faible du côté amont, donc en opposition au sens de rotation des ailettes 34 de l'écoulement tangentiel du fluide, que du côté aval. On voit à la figure 3 une illustration des courants dans le mélange en projection du plan normal à l'axe du batteur 3. Ces saillies déflectrices 12 peuvent sans difficulté être venues d'une pièce avec la surface 1 et le fond 11 du flacon dans leur réalisation par soufflage, comme il apparait d'ailleurs clairement aux figures 2 et 3.To increase the efficiency of the beater 3 in producing a perfectly homogeneous mixture, it is further sought to cause turbulence or swirl along the wall of the bottle 1. For this purpose, this wall is provided with at least two longitudinal deflecting projections 12 extending over all or part of the height of the bottle and leaving sufficient clearance for the passage of the fins 34. These deflecting projections 12 slow down the rotating current of the fluid on the wall of the bottle 1, which ensures better brewing. For optimum efficiency, the deflecting projections 12, in the form of a tooth with a triangular section, advantageously have a lower slope on the upstream side, therefore in opposition to the direction of rotation of the fins 34 of the tangential flow of the fluid, than on the downstream side. . FIG. 3 shows an illustration of the currents in the mixture in projection from the plane normal to the axis of the mixer 3. These deflecting projections 12 can easily come from a single piece with the surface 1 and the bottom 11 of the bottle in their production by blowing, as is moreover clearly shown in FIGS. 2 and 3.

On peut évidemment prévoir un plus grand nombre de saillies déflectrices, mais la configuration de la plaque de maintien 33 en serait compliquée pour permettre son introduction aisée dans le flacon 1 et par ailleurs, deux saillies 12 semblent suffisantes pour atteindre un excellent résultat en ce qui concerne l'homogénéité du mélange polymérisable.It is obviously possible to provide a greater number of deflecting projections, but the configuration of the retaining plate 33 would be complicated to allow its easy introduction into the bottle 1 and moreover, two projections 12 seem sufficient to achieve an excellent result as regards concerns the homogeneity of the polymerizable mixture.

Le flacon mélangeur décrit plus haut peut, comme déjà dit, servir de conditionnement du constituant liquide de base du mélange, le batteur 3 y étant également contenu ou y étant rapporté avant de procéder à l'opération de mélange.The mixing bottle described above can, as already said, serve as a packaging for the basic liquid constituent of the mixture, the beater 3 being also contained therein or attached thereto before proceeding to the mixing operation.

Pour la réalisation d'un rembourrage de mousse expansée, on opère de la manière exposée dans ce qui suit.For the production of expanded foam padding, the procedure is as explained below.

Un tuyau de connexion est disposé sur la chaussure et commu­nique avec de préférence l'intérieur d'une enveloppe textile étanche au produit polymérisable et perméable aux gaz, ce qui facilitera l'élimination de ceux-ci sans nécessité d'ouverture supplémentaire pour l'évacuation. Comme déjà dit, avec deux ajutages 4 sur le couvercle 2 du flacon mélangeur 1, on va pouvoir opérer dans les mêmes conditions sur les deux chaussures simultanément.A connection pipe is placed on the shoe and preferably communicates with the inside of a textile envelope which is impermeable to the polymerizable and gas permeable product, which will facilitate the elimination of these without the need for additional opening for the evacuation. As already said, with two nozzles 4 on the cover 2 of the mixing bottle 1, we will be able to operate under the same conditions on the two shoes simultaneously.

On verse ensuite le second produit, contenu jusqu'alors dans un flacon séparé, dans le flacon mélangeur 1 contenant déjà le premier produit et on en referme le couvercle 2 porteur du batteur 3. Le ou les tuyaux de connection sont branchés sur les ajutages 4. Le flacon mélangeur 1 restant en position sensiblement verticale, on procède au mélange par entrainement en rotation du batteur 3, par exemple au moyen d'un outil motorisé du type perceuse, jusqu'à obtention d'un mélange parfaitement homogène. Le temps nécessaire au mélange dépend évidemment de la matière des composants pour obtenir par expansion une mousse de qualité régulière en vue d'un bon confort et une tenue ultérieure correcte du pied du porteur. La maîtrise de ce temps de mélange, ni trop court, ni trop long s'acquiert très rapidement puisqu'il n'y a plus aucune intervention manuelle pour la préparation du mélange.The second product, then contained in a separate bottle, is then poured into the mixing bottle 1 already containing the first product and the cover 2 carrying the mixer 3 is closed. The connection pipe or pipes are connected to the nozzles 4 The mixing bottle 1 remaining in a substantially vertical position, mixing is carried out by rotating the beater 3, for example by means of a motorized tool of the drill type, until a perfectly homogeneous mixture is obtained. The time required for mixing obviously depends on the material of the components in order to obtain by expansion a foam of regular quality with a view to good comfort and a correct subsequent holding of the wearer's foot. The control of this mixing time, neither too short nor too long, is acquired very quickly since there is no longer any manual intervention for the preparation of the mixture.

Après un temps de réaction nécessaire relativement court, on porte le flacon mélangeur 1 en position haute par rapport aux points d'injection et on le bascule suffisamment pour entrainer l'écoulement du mélange par gravité et par la pression gazeuse naturelle qui se crée dans le flacon mélangeur 1, dans les tubes de connexion pour remplir l'espace à rembourrer.After a relatively short necessary reaction time, the mixing vial 1 is brought to the high position relative to the injection points and is tilted enough to cause the flow of the mixture by gravity and by the natural gas pressure which is created in the mixing bottle 1, in the connection tubes to fill the space to be stuffed.

Après expansion de la mousse et polymérisation, les tubes de connexion sont arrachés de la chaussure et sont jetés avec le flacon mélangeur 1.After expansion of the foam and polymerization, the connection tubes are torn from the shoe and are discarded with the mixing bottle 1.

Comme on le voit, on peut procéder à l'injection simultanée dans les deux chaussures et non dans l'une, puis dans l'autre. Le nombre des récipients pour les produits liquides à mélanger n'a donc pas à être multiplié par deux, de même que le nombre de manipulations, comme c'est le cas selon les techniques habituelles. Le prix de revient du résultat final est donc nettement plus faible que celui que permet cet état de la technique.As we can see, we can proceed to the simultaneous injection in the two shoes and not in one, then in the other. The number of containers for the liquid products to be mixed therefore does not have to be doubled, as is the number of manipulations, as is the case according to the usual techniques. The cost price of the final result is therefore much lower than that which this prior art allows.

Dans le cas où le flacon mélangeur 1 est le conditionnement même du produit liquide de base, comme évoqué en début de description, il est clair qu'il est alors fermé par un couvercle de préférence tradition­nel. Pour réaliser l'injection du rembourrage, il s'avère alors optimal de brancher d'abord le ou les tuyaux de connexion sur le couvercle 2 porteur du batteur 3. On enlève alors le couvercle traditionnel du flacon 1 et on verse le second produit liquide dans ce flacon 1, on referme ensuite le flacon 1 en le vissant sur le couvercle 2 porteur du batteur 3, et on opère ensuite comme déjà dit. Du fait de la rapidité de la réaction, il est en effet préférable de brancher les ajutages 4 avant fermeture du couvercle 2.In the case where the mixing bottle 1 is the actual packaging of the basic liquid product, as mentioned at the beginning of the description, it is clear that it is then closed by a preferably traditional cover. To carry out the injection of the padding, it is then optimal to first connect the connection pipe or pipes to the cover 2 carrying the beater 3. The traditional cover of the bottle 1 is then removed and the second liquid product is poured in this bottle 1, the bottle 1 is then closed by screwing it onto the cover 2 carrying the mixer 3, and then the operation is carried out as already said.
