Abstract

The device has a set of main elements (7-9) forming an exact replica of concerned feet when the elements are assembled with each other. The main elements are assembled and locked with each other by mating along planes beveled through one of the elements. Guides are engaged between the elements so as to increase interior deformation of a shoe. Shape of the elements is locally modified by applying cement polyester or similar products. A pre-molding box molded by a machine tool with digital controller is used to realize the device.

Description

la sème invention cancenre eliapositifpermettant d'adapter ia rue utérine des emmures à k faune des pieds auxquelles celles-ci sont destinées. Cette interventian end pas en compte la forme de la voute plantaire de la clamser. Beaucoup de personnes ont des difficultés pour se chausser soit qu'elles aient un pied fort que l'autre ou et'dles s de légères déformations dunnalismales ou autres. S'il (Mg' e beaace%) de types d'embauchoirs' qui permettent d'agrandir les chaussures Ils pennetteast pas toujours de bien cibler et d'agir sur la zone à défouler. Autre po té enduire la partie de la chaussure à déformer d'un produit permettant Patiemment du cuir et demander au pied concerné d'agir sur cette partie, on peut obtenir un résultat mais c'est 14 toujours douloureux. Le dispositif selon l'invention permet dans bien des cas de ' ces inconvénients. Il se compose d'un embauchoir réalisé à l'identique du pied recevant la chaussure, ou les chaussures concernées. De plus cet embauchoir est réalisé al phasiturs parties qui s'assembles de façon à être facilement introduites et bloquées dans la chaussure afin que cule-ci prenne la forme intérieure du pied à La réalisation de ce dispositif selon l'invention peut être obtenue de différentes façons : Soit en numérisant la forme du pied concerné en 3 dimensions sur un progiamme informatipe et en réalisant ensuite l'embauchoir sur u©e machine outils à commande namédque_ Soit par prise d'empreinte du pied concerné et e*dage en résine ou plâtre meut= prudes de Vie. A titre d'exemple non limitatif et suivant les dessins annexés dont certains illustmnt l'imitation (input procéder comme suit En premier à l'aide d'un caisson de pernoulage à usage non destructif figure 1 et 2 pour pieds droits, le caisson pour le pied gauche est kleatique mais symétrique, on procède à la réalisation de la prise d'empreinte du pied concerné, matérialisée par un léger moule réalisé en plâtre de moulage, voire) figure 3 Pourcette opération la protection du pie' d du patient concerné lors du coulage du plâtre est assurée Par utt simple film étirable. Avant séchage da plâtre ou procède à l'aide d'une petite lame de 2/10 de mm non coupante à la séparation des &Momies parties du moule en 30 glissant celle-ci entre les plans de joint des mises: (1) (2) (3) (4) figtue 1 qui sont prévus pour ceci Le démoulage se fait par séparation des quatre eus repère (1) (2) (3) (4) figure 1 donc sans efforts et sans risque. Ensuite après l'opération de démoulage on reconstitue l'ensemble caisson de pré-moulage et moule d'empreinte et l'on procède au -2- coulagede l'air généralement en trois parties 4. obtient cette forme en trois parties distinctes grâce à la pose des 2 séparateurs (5) de la figure 4 lors da coulage, les lumières nécessaires à l'introduction des séparateurs ne sont pas représentés sur les dessins. Pour des cas particuliers d'adaptation de la chaussure, exemple ladéfonnatio. n du pied concerné (11) on peut obtenir la forme de l'embauchoir plus de trois parties voir en exemple non limitatif la figure 5 représentant la pose d'un autre séparateur repère10. La résine de coulée s'emploie chargée avec du micro ballon ou autres produits afin d'obtenir un embauchoir suivant l'invention le plus léger et le plus résistant possible. Après polymérisation de l'ensemble on procède au démoulage on obtient alors les 3 parties principales (7) (8) (9) figure 6 de l'embauchoir suivant l'invention_ On peut alors après avoir enduit à l'intérieur de la chaussure les parties à déformer d' produit du commerce permettant au cuir de se déformer introduire le dispositif embauche; selon l'invention à l'intérieur de la chaussure. Introduire en premier l'élément (7) ensuite l'élément (9) et engager l'élément (8) voir figure 7. Repousser ensuite l'élément biseauté 15 (8) jusqu'à qu'il arrivé en butée voir figure 8, l'ensemble ébauchoir selon l'invention sera alors parfaitement en place. Il suffit de laisser agir quelques heures jusqu'à ce que la chaussure ait pris la forme de l'embauchoir. Au cas ou la déformation ne serait pas suffisante en longueur on peut en plus engager un ou plusieurs intercalaire (10) entre les formes (8) et (9) ou (7) et (8), procéder de même si nécessaire pour la largeur en glissant un intercalaire au point de séparation de l'élément (7) voir figure 5. De même au cas ou si par la suite de nouvelles de nouvelles malformations correspondant à l'embauchoir apparaissent il est possible de modifier l'embauchoir par apport de mastic polyester ou autres produits similaires aux endroits correspondant. L'ébauchoir selon l'invention est illustré de façon à intervenir sur des chaussures basses 25 mais avec des caissons de pré-moulage permettant une prise d'empreinte au dessus de la cheville on peut de même agir sur des chaussures à tige. Le dispositif embauchoir est destiné à adapter le mieux possible les chaussures aux concernés afin d'apporter à ceux qui les portent le plus de confort possible.the fifth cancerous invention made it possible to adapt uterine uterine walls to the fauna of the feet for which they are intended. This intervention does not take into account the shape of the plantar arch of the clamser. Many people have difficulties in putting on shoes, whether they have one strong foot or the other, or they have slight distortions of ethnicity or otherwise. If it (Mg 'e beaace%) of types of shoe trees' which allow to enlarge the shoes They pennetteast not always to target well and to act on the zone to let off steam. Other po te coat the part of the shoe to deform a product patiently allowing leather and ask the foot concerned to act on this part, we can get a result but it is 14 always painful. The device according to the invention allows in many cases these disadvantages. It consists of a shoe tree made identical to the foot receiving the shoe, or the shoes concerned. In addition this shoe is made al phasiturs parts which are assembled so as to be easily introduced and blocked in the shoe so that it takes the inner shape of the foot to the realization of this device according to the invention can be obtained from different ways: Either by digitizing the shape of the foot concerned in 3 dimensions on a computer program and then realizing the shoe tree on a machine with tools namédque_ Or by taking impression of the foot concerned and é * dage resin or plaster meut = prudes of Life. By way of nonlimiting example and according to the accompanying drawings, some of which illustrate the imitation (input proceed as follows Firstly with the aid of a non-destructive subwoofer box FIGS. 1 and 2 for straight feet, the box for the left foot is kleatic but symmetrical, one carries out the realization of the impression of the foot concerned, materialized by a light mold made in casting plaster, even) figure 3 For this operation the protection of the pie 'd of the patient concerned during plaster casting is ensured by utt simple stretch film. Before drying the plaster or proceed with the aid of a small blade of 2/10 mm non-cutting at the separation of & Mummies parts of the mold by sliding it between the joint planes bet: (1) (2) ) (3) (4) figtue 1 which are provided for this The demolding is done by separating the four eus mark (1) (2) (3) (4) Figure 1 so without effort and without risk. After the demolding operation, the pre-molding box assembly and the impression mold are reconstituted, and the air is generally divided into three parts. This form is obtained in three distinct parts by means of the laying of the 2 separators (5) of FIG. 4 during casting, the lights necessary for the introduction of the separators are not shown in the drawings. For special cases of adaptation of the shoe, example deformation. n of the foot concerned (11) can be obtained the shape of the tree more than three parts see a non-limiting example, Figure 5 showing the installation of another separator mark10. The casting resin is used charged with micro balloon or other products to obtain a tree shoe according to the invention the lightest and most resistant possible. After polymerization of the assembly is carried out demolding is then obtained the 3 main parts (7) (8) (9) Figure 6 of the shoe tree according to the invention_ can then after having coated inside the shoe parts for deforming the product of the trade allowing the leather to be deformed to introduce the hiring device; according to the invention inside the shoe. Introduce first the element (7) then the element (9) and engage the element (8) see figure 7. Then push the beveled element (8) until it reaches the stop see figure 8 , the set of blanks according to the invention will then be perfectly in place. Just let it work for a few hours until the shoe has taken the shape of the shoe tree. In case the deformation is not sufficient in length, it is also possible to engage one or more spacers (10) between the shapes (8) and (9) or (7) and (8), to proceed in the same way if necessary for the width by sliding an interlayer to the point of separation of the element (7) see Figure 5. Similarly in the case or if later news of new malformations corresponding to the shoe tree appear it is possible to modify the tree shoe by contribution of polyester putty or other similar products at the corresponding places. The blank according to the invention is illustrated so as to operate on low shoes 25 but with pre-molding boxes allowing an impression above the ankle can also act on shoes with a stem. The device tree shoe is designed to best fit the shoes to those concerned to bring to those who wear them the most comfort possible.
