Description

La présente invention a pour objet un dispositif de botte apte à épouser intérieurement la forme du pied, notammement en certains points, en vue de protéger lesdits points contre d'éventuels chocs, ledit dispositif de botte étant particulièrement adapté à la pratique de la moto.The present invention relates to a boot device capable of marrying the shape of the foot internally, in particular at certain points, with a view to protecting said points against possible shocks, said boot device being particularly suitable for the practice of motorcycling.

On sait que les pieds et les jambes d'un motard sont particulièrement exposés aux chocs, et notamment les tibias et les malléoles. Afin de protéger ces points sensibles les bottes de moto comportent des renforts localisés sur lesdits points, ces renforts étant généralement des bourrelets extérieurs servant d'amortisseurs.We know that the feet and legs of a biker are particularly exposed to shocks, especially the shins and malleoli. In order to protect these sensitive points, the motorcycle boots include reinforcements located on said points, these reinforcements generally being external beads serving as shock absorbers.

Dans certains cas, pour améliorer la protection, la botte comporte, outre les bourrelets extérieurs, une coque intérieure moulée, rigide ou semi-rigide, ayant sensiblement la forme du pied, la fermeture de ladite botte étant assurée par des sangles réparties sur la hauteur permettant d'appliquer ladite coque sur le pied.In some cases, to improve protection, the boot comprises, in addition to the outer beads, a molded, rigid or semi-rigid inner shell, having substantially the shape of the foot, the closure of said boot being provided by straps distributed over the height allowing to apply said shell to the foot.

L'inconvénient de ces dispositifs est l'inconfort, particulièrement en ce qui concerne ceux comportant une coque intérieure rigide ou semi-rigide, du fait que tous les pieds n'ayant pas la même morphologie, le moindre déplacement du pied dans la butte peut causer une gêne et également entraîner la blessure du pied en cas de choc.The disadvantage of these devices is the discomfort, particularly with regard to those comprising a rigid or semi-rigid inner shell, because all the feet not having the same morphology, the slightest displacement of the Foot in the mound can cause discomfort and also cause injury to the foot in the event of impact.

On connaît d'autre part des dispositifs permettant de modifier la forme intérieure d'une chaussure, notamment pour la pratique du sport, en gonflant d'air une enveloppe contenue dans la tige de manière à bloquer le pied dans ladite chaussure et éviter qu'il ne s'y déplace.On the other hand, devices are known which make it possible to modify the internal shape of a shoe, in particular for the practice of sport, by inflating air with an envelope contained in the upper so as to block the foot in said shoe and avoid that it does not move there.

Ces dispositifs sont parfaitement adaptés au blocage du pied, mais ne permettraient pas un amortissement suffisant en cas de choc s'ils étaient mis en place sur une botte du type botte de moto, du fait qu'il n'est pas possible d'obtenir une pression d'air suffisante pour résister à un écrasement.These devices are perfectly suited for blocking the foot, but would not allow sufficient cushioning in the event of an impact if they were fitted on a boot of the motorcycle boot type, since it is not possible to obtain sufficient air pressure to resist crushing.

Pour remédier à ces inconvénients la demanderesse a proposé, dans sa demande de brevet FR 92/11934 , un dispositif de protection des endroits du pied exposés aux chocs, par insertion dans la tige d'une botte, en regard desdits endroits, d'au moins une enveloppe étanche déformable contenant un produit fluide de viscosité élevée, de type gel, apte à épouser les formes du pied sous la pression exercée par une enveloppe gonflable, au moyen d'une pompe de type connu, recouvrant ladite enveloppe contenant le produit fluide.To remedy these drawbacks, the applicant has proposed, in its patent application FR 92/11934, a device for protecting the places of the foot exposed to shocks, by insertion into the upper of a boot, opposite said places, at less a deformable waterproof envelope containing a fluid of high viscosity, gel type, capable of conforming to the shapes of the foot under the pressure exerted by an inflatable envelope, by means of a pump of known type, covering said envelope containing the fluid product .

Si ce dispositif donne entière satisfaction en ce qui concerne le confort et l'amortissement des chocs, il n'en présente pas moins des inconvénients de tenue dans le temps. En effet à force de gonflage et sous l'effet des chocs, l'enveloppe gonflable perd son étanchéité et ne permet plus la mise sous pression de l'enveloppe de produit visqueux. En outre, l'enveloppe gonflable étant de fait la première exposée aux chocs, si ceux-ci sont causés par des objets anguleux il y a risque de crevaison.If this device is entirely satisfactory with regard to comfort and shock absorption, it nevertheless has drawbacks of resistance over time. Indeed by inflation force and under the effect of shocks, the inflatable envelope loses its tightness and no longer allows the pressurization of the viscous product envelope. In addition, the inflatable envelope being in fact the first exposed to shocks, if these are caused by angular objects there is a risk of puncture.

La présente invention vise à remédier à ces inconvénients en proposant un dispositif de botte perfectionné qui se caractérise essentiellement en ce qu'il comporte, insérées dans la tige de la botte, en regard des zones du pied à protéger, des enveloppes de protection étanches, déformables et gonflables au moyen d'un produit fluide de viscosité adaptée, par injection dudit produit fluide contenu, préalablement à l'injection, dans un réservoir compressible positionné dans la botte à un endroit protégé, ledit réservoir étant disposé dans une enceinte non extensible et étant susceptible d'être comprimé, par injection d'un gaz dans ladite enceinte non extensible ou dans une enveloppe gonflable disposée, à l'intérieur de ladite enceinte, au contact dudit réservoir.The present invention aims to remedy these drawbacks by proposing an improved boot device which is essentially characterized in that it comprises, inserted in the upper of the boot, opposite the areas of the foot to be protected, waterproof, deformable and inflatable protective envelopes by means of a fluid product of suitable viscosity, by injection of said fluid product contained, prior to injection, in a compressible reservoir positioned in the boot at a location protected, said tank being disposed in a non-expandable enclosure and being capable of being compressed, by injection of a gas into said non-expandable enclosure or into an inflatable envelope disposed, inside said enclosure, in contact with said tank.

Lors de l'injection de gaz, la pression exercée sur le réservoir de fluide en chasse ce dernier, qui remplit les enveloppes de protection. De manière avantageuse, le dispositif selon l'invention permet d'injecter dans les enveloppes de protection la quantité de fluide juste nécessaire au confort de la botte.During the injection of gas, the pressure exerted on the fluid reservoir drives out the latter, which fills the protective envelopes. Advantageously, the device according to the invention makes it possible to inject the amount of fluid just necessary for the comfort of the boot into the protective envelopes.

Inversement la vidange du gaz injecté a pour effet de supprimer la pression exercée sur le réservoir, qui par dépression reprend sa forme initiale et aspire le fluide, aidé en cela par la pression exercée par le pied sur les enveloppes de protection.Conversely, the emptying of the injected gas has the effect of removing the pressure exerted on the reservoir, which by vacuum resumes its initial shape and sucks the fluid, aided in this by the pressure exerted by the foot on the protective envelopes.

Selon un mode de réalisation du dispositif selon l'invention, l'enceinte non extensible renferme, disposée au contact du réservoir de produit fluide, une enveloppe étanche gonflable à l'air, ou autre gaz.According to one embodiment of the device according to the invention, the non-expandable enclosure contains, arranged in contact with the reservoir of fluid product, a sealed envelope inflatable with air, or other gas.

Selon un autre mode de réalisation du dispositif selon l'invention, l'enceinte non extensible est elle-même étanche et l'air, ou autre gaz, y est directement injecté.According to another embodiment of the device according to the invention, the non-expandable enclosure is itself sealed and the air, or other gas, is directly injected there.

Dans l'un ou l'autre cas le gaz injecté l'est par tout moyen approprié, tel qu'une pompe extérieure de type connu ou une cartouche de gaz sous pression.In either case the gas injected is by any suitable means, such as an external pump of known type or a cartridge of gas under pressure.

Le gaz utilisé à cet effet est de préférence l'air, mais peut être aussi tout autre gaz susceptible de convenir à cet usage.The gas used for this purpose is preferably air, but may also be any other gas capable of being suitable for this use.

Le produit fluide disposé dans le réservoir et destiné à remplir les enveloppes de protection est de préférence un produit de viscosité assez élevée, par exemple un gel ou un mélange d'un gel et d'un liquide tel que l'eau.The fluid product placed in the tank and intended to fill the protective envelopes is preferably a product of fairly high viscosity, for example a gel or a mixture of a gel and a liquid such as water.

Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

Dans le dessin annexé :

  • la figure 1 représente une vue schématique de profil d'un dispositif de botte selon l'invention, avant insufflation d'air.
  • la figure 2 représente une vue schématique de profil du même dispositif lors de l'insufflation d'air.
In the attached drawing:
  • FIG. 1 represents a schematic profile view of a boot device according to the invention, before blowing air.
  • 2 shows a schematic profile view of the same device during the air blowing.

Si on se réfère à la figure 1 on peut voir qu'une botte 1 selon l'invention comporte dans une partie protégée, par exemple en partie arrière, une enceinte inextensible 2 contenant deux enveloppes 20 et 21 étanches et déformables.If we refer to Figure 1 we can see that a boot 1 according to the invention comprises in a protected part, for example in the rear, an inextensible enclosure 2 containing two envelopes 20 and 21 waterproof and deformable.

L'enveloppe 20 est reliée par un tuyau 22 à un moyen d'insufflation 23 d'air ou autre gaz, par exemple une pompe manoeuvrable depuis l'extérieur, ou une cartouche de gaz amovible.The casing 20 is connected by a pipe 22 to a means 23 for blowing air or other gas, for example a pump which can be operated from the outside, or a removable gas cartridge.

L'enveloppe 21, qui contient un fluide 24, de préférence de viscosité élevée, de type gel, est reliée par l'intermédiaire d'un tuyau 25 à au moins une enveloppe de protection 3 insérée dans la tige 10 de la botte 1 en regard d'une zone du pied à protéger.The casing 21, which contains a fluid 24, preferably of high viscosity, of the gel type, is connected via a pipe 25 to at least one protective casing 3 inserted in the upper 10 of the boot 1 in look of an area of the foot to be protected.

Si on se réfère maintenant à la figure 2 on peut voir que sous l'action du moyen d'insufflation 23, l'enveloppe 20 se gonfle et comprime l'enveloppe 21 dont le contenu, à savoir le fluide 24, est chassé dans le tuyau 25 et remplit l'enveloppe de protection 3.Referring now to FIG. 2, it can be seen that under the action of the insufflation means 23, the envelope 20 swells and compresses the envelope 21, the content of which, namely the fluid 24, is expelled into the hose 25 and fills the protective envelope 3.

Outre la pratique de la moto, le dispositif de botte selon l'invention peut également être utilisé pour des raisons de confort et de sécurité dans d'autres activités sportives ainsi que dans des activités présentant des risques de blessures aux pieds, par exemple sur des chantiers ou dans des usines.Besides the practice of motorcycling, the boot device according to the invention can also be used for reasons of comfort and safety in other sports activities as well as in activities presenting risks of injury to the feet, for example on construction sites or factories.
