Abstract

The subject of the present invention is a method for improving the comfort of dancing shoes and, in this case, to distribute the weight of the body over all the toes in the points position, as well as a product for implementing the method, characterised principally in that it comprises the stages consisting in accelerating and/or catalysing a base (1, 2, 1', 2') of elastomer which can be polymerised at ambient temperature, the said base being in a state of fluidity with a high thixotropic character and with low adhesion, then forming therewith, rapidly, a ball (3) of the size of a walnut, then introducing the said ball into the toe (5) of the shoe and roughly lining the wall therewith, then in introducing the foot therein so that the still fluid material is distributed into the free spaces (7) between the toes and the wall of the shoe, then placing the shod foot in the points position without pressing, then placing the foot flat again and waiting for the base to be polymerised, keeping the foot as stationary as possible.

Description

La présente invention a pour objet un procédé pour améliorer le confort des chaussures, notamment des chaussons de danse et dans ce cas répartir le poids du corps sur l'ensemble des orteils en position de pointes, ainsi qu'un produit pour la mise en oeuvre du procédé. The subject of the present invention is a method for improving the comfort of shoes, in particular dance slippers and in this case distributing the weight of the body over all of the toes in the point position, as well as a product for the implementation. of the process.

On connait divers palliatifs à l'inconfort des chaussures et particulièrement des chaussons : introduction d'un garnissage d'ouate, de mousse élastique. On a aussi proposé des structures particulières: on pourra se reporter aux brevets EP-OO7()ûG3 !BALLE),
EP-0136936 (Sté Fr. d'Orthopédie), F#-234424l (MONTIES-CHA-
DOUA, IswLmT).
There are various palliative known to the discomfort of shoes and particularly of slippers: introduction of a wadding, elastic foam. We have also proposed specific structures: reference may be made to patents EP-OO7 () ûG3! BALL),
EP-0136936 (Sté Fr. d'Orthopédie), F # -234424l (MONTIES-CHA-
DOUA, IswLmT).

On connait par brevet européen EP-O136415 un moyen d'une telle amélioration du confort d'un chausson de danse, moyen consistant en un petit sachet formé d'une mince membrane, et contenant un mélange de chaux de paraffine et de craie, le sachet étant revêtu d'une pellicule de chevreau ; on doit porter le sachet à température de ramollissement de la cire puis le placer dans le chausson puis y introduire le pied ; aprés refroidissement le sachet est réparti dans l'espace libre entre le bout des orteils et la pointe du chausson et il conserve sa défcïmation en permanence.Un inconvénient principal tient à ce que la masse refroidie n'a aucune élasticité ; en outre la mise en oeuvre est assez difficile en raison du chauffage nécessaire ; enfin le résultat de confort est souvent médiocre en raison du fait que le sachet et le chevreau qui le recouvre ne sont que trop faiblement extensibles. We know from European patent EP-0136415 a means of such an improvement in the comfort of a dance shoe, means consisting of a small sachet formed of a thin membrane, and containing a mixture of paraffin lime and chalk, the sachet being coated with a kid film; the bag should be brought to the softening temperature of the wax, then placed in the slipper and then the foot inserted therein; after cooling the sachet is distributed in the free space between the tips of the toes and the tip of the liner and it retains its permanent defcimation. A main drawback is that the cooled mass has no elasticity; in addition the implementation is quite difficult due to the heating required; Finally, the comfort result is often poor due to the fact that the bag and the kid covering it are only too weakly extensible.

Le présent Demandeur, podologue de profession, utilise pour les soins de certaines affections du pied un emplâtre bicomposant à base de silicone ; la technique consiste à recouvrir un orteil, ou tout autre partie du pied normalement en contact avec la chaussure, d'une couche de l'emplâtre et d'attendre la polymérisation placé entre deux orteils voisins l'emplâtre évitera la fric tion de l'un contre l'autre. Un tel emplâtre, utilisable également pour la prise d' empreinte dentaire, est décrit dans le brevet FR-2602781 (RHONE-POULENC) qui fournit la composition, à savoir une composition diorgano-polysiloxane pâteuse chargée vulcanisable à température ambiante répartie en deux conditionnements, l'un comprenant un catalyseur au platine, l'autre un organo hydrogenopolysiloxane. The present Applicant, a podiatrist by profession, uses a two-component silicone-based plaster for the treatment of certain conditions of the foot; the technique consists in covering a toe, or any other part of the foot normally in contact with the shoe, with a layer of the plaster and waiting for the polymerization placed between two neighboring toes the plaster will avoid fric tion of the one against the other. Such a plaster, which can also be used for taking dental impressions, is described in patent FR-2602781 (RHONE-POULENC) which provides the composition, namely a pasty diorgano-polysiloxane composition containing a vulcanizable charge at room temperature divided into two packages, one comprising a platinum catalyst, the other an organo hydrogenopolysiloxane.

Le présent Demandeur, que sa profession amenait souvent à intervenir pour des blessures des pieds des danseuses causées par la pratique des "pointes , a eu alors l'idée de, non plus applique l'-mLlâtee à titre curatif, mais le disposer dans le chausson de danse préalablement à l'introduction du pied de la danseuse. The present Applicant, whom his profession often led to intervene for injuries to the feet of dancers caused by the practice of "pointe shoes", then had the idea of no longer applying the -mLlatee for curative purposes, but disposing it in the dance shoe before the introduction of the dancer's foot.

Aprés quelques tâtonnements sur la quantité et la manière de le disposer, il a pu recueuillii la satifaction des utilisatrices.After some trial and error on the quantity and how to dispose it, it was able to receive the satisfaction of the users.

Ainsi, et selon la présente invention, un procédé destiné à améliorer le confort de certaines chaussures, notamment des chaussons de danse, du genre de procédé consistant à ménager à la pointe du chausson un coussinet épousant aussi étroitement que possible la forme de l'extrémité du pied, est caractérisé en ce qu'il comprend les étapes consistant à al accélérer et/ou catalyser une base d'élastomère polymérisable à température ambiante, la dite base étant dans un état de fluidité à fort caractère thixotrope et à faible adhérence, puis b) en former rapidement une boule de la grosseur d'une noix, puis introduire ladite boule dans la pointe du chausson et en tapisser grossièrement la paroi, puis c) y introduire le pied de telle sorte que la matière encore fluide se répartisse dans les interstices libres entre les orteils et la paroi du chausson, puis d) mettre le pied chaussé en position de pointes sans appuyer, puis remettre le pied à plat et attendre que la base soit soit polymerisée en laissant le pied aussi immobile que possible. Thus, and according to the present invention, a method intended to improve the comfort of certain shoes, in particular ballet slippers, of the type of method consisting in providing at the tip of the slipper a pad which conforms as closely as possible to the shape of the end of the foot, is characterized in that it comprises the stages consisting in accelerating and / or catalyzing a base of elastomer which can be polymerized at room temperature, said base being in a state of fluidity with a strong thixotropic character and a low adhesion, then b) quickly form a ball the size of a walnut, then introduce said ball into the tip of the bootie and roughly line the wall, then c) introduce the foot so that the still fluid material is distributed in the free gaps between the toes and the wall of the liner, then d) put the foot in the toe position without pressing, then put the foot flat and wait e that the base be polymerized leaving the foot as immobile as possible.

L'invention porte aussi sur l'application nouvelle d'une base d'élastomère consistant en une composition diorgano-polysiloxane pateuse chargée vulcanisable à température ambiante, répartie en deux conditionnements séparés, l'un comprenant un catalyseur au platine, l'autre un organo-hydrogenopolysiloxane, application suivant laquelle la base sert à tapisser l'intérieur de 1V extrémIté d'un chausson, notamment un chausson de danse, le taven^L!en; ainsi forme ayant sa surface inse-.X~ conformée au relief de l'extrémité du pied suivant le procédé sus-défini. The invention also relates to the novel application of an elastomer base consisting of a pasty diorgano-polysiloxane composition filled with vulcanization at room temperature, distributed in two separate packages, one comprising a platinum catalyst, the other a organo-hydrogenopolysiloxane, application according to which the base is used to line the interior of the extremity of a shoe, in particular a dance shoe, the taven ^ L! en; thus form having its surface inse-.X ~ shaped to the relief of the end of the foot according to the above-defined process.

La présente invention sera mieux comprise à la description qui va en être faite en relation avec les dessins de la planche unique annexée dans laquelle
- la fig.l est une illustration schématique du procédé, et
- la fig.2, une illustration de la finalité de l'invention.
The present invention will be better understood from the description which will be made of it in relation to the drawings of the single sheet appended in which
- Fig.l is a schematic illustration of the process, and
- Fig.2, an illustration of the purpose of the invention.

Sur la fig.l, en traits pleins, une première variante du procédé de l'invention consiste à mélanger deux parties 1,2 d'une base d'élastomère, l'une (1) de ces parties comprenant le catalyseur et un monomère (ou un polysiloxane) stable vis à vis de l'action du catalyseur, et l'autre (2) un polysiloxane réactif (organohydrogénopolysiloxane) ; le mélange est effectué par pétrissage manuel d'un volume équivalent à celui d'une noix, le temps de pétrissage est de une à deux minutes ; on forme alors une boulette 3 que l'on introduit dans la pointe 5 du chausson 6 et dont on tapisse la paroi et l'extrémité, dite coque; on introduit ciors le pied dans le chausson, puis on seplace en position de pointes sans trop appuyer(fig.2), pui on replace le pied à plat, immobile, et après environ cinq minutes de maintien immobile du pied on a réalisé un coussinet 7 élastique assez souple (dureté Shore comprise entre 20 et 40). La fig.2 montre, à 900 de la figure précédente, comment un pied d'une danseuse prend appui sur le coussinet. In FIG. 1, in solid lines, a first variant of the process of the invention consists in mixing two parts 1,2 of an elastomer base, one (1) of these parts comprising the catalyst and a monomer (or a polysiloxane) stable with respect to the action of the catalyst, and the other (2) a reactive polysiloxane (organohydrogenopolysiloxane); mixing is carried out by manual kneading of a volume equivalent to that of a walnut, the kneading time is one to two minutes; a pellet 3 is then formed which is introduced into the point 5 of the liner 6 and the wall and the end of which are coated, called the shell; we introduce the foot into the liner, then we move to the point position without pressing too hard (fig. 2), then we replace the foot flat, immobile, and after about five minutes of immobile support of the foot we made a pad 7 fairly flexible elastic (Shore hardness between 20 and 40). Fig. 2 shows, at 900 of the previous figure, how a foot of a dancer is supported on the pad.

On a représenté toujours sur la fig.l, par 1' et 2', une autre composition de base formée d'un monomère d'élastomère 2' et de son agent 1' de polymérisation à froid, la base pouvant être un polysiloxane, comme sus-décrit, mais aussi un polyuréthane faiblement réticulé. Still shown in FIG. 1, by 1 ′ and 2 ′, another base composition formed from an elastomer monomer 2 ′ and its agent 1 ′ for cold polymerization, the base possibly being a polysiloxane, as described above, but also a weakly crosslinked polyurethane.

Grace à l'invention, le poids du corps est réparti sur l'ensemble des orteils, et ceuxci, et particulièrement sur leur face supérieure et sur les corps internes et externes du chausson, sont p^olng~i des frottements contre la paroi du chausson. Thanks to the invention, the body weight is distributed over all of the toes, and these, and particularly on their upper face and on the internal and external bodies of the boot, are p ^ olng ~ i friction against the wall of the slipper.

Bien que l'on ait décrit et représenté une forme préférée de réalisation, il doit être compris que la portée de la présente invention n'est pas limitée à cette forme mais qu'elle s'étend à tout dispositif comportant les caractéristiques ennoncées plus haut.  Although a preferred embodiment has been described and shown, it should be understood that the scope of the present invention is not limited to this form but that it extends to any device comprising the characteristics stated above. .
