Description

CHAUSSURE A USAGE MULTIPLE MULTI-PURPOSE SHOE
La présente invention concerne le domaine des chaussures. De manière plus précise, les chaussures selon l'invention possèdent des moyens pour accueillir, soit plu- sieurs talons interchangeables, soit un organe à fin de rééducation.The present invention relates to the field of shoes. More specifically, the shoes according to the invention have means for accommodating either several interchangeable heels or a body for rehabilitation.
ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION
Dans le domaine des chaussures, il existe une demande de pouvoir changer l'apparence d'une chaussure, no- tamment une chaussure de femme, en ayant la possibilité de changer la forme ou la matière ou la couleur du talon de la chaussure tout en gardant la même partie chaussante. Par ailleurs, certaines chaussures peuvent constituer des instruments d'entraînement ou de rééducation en offrant à l'usager différentes sortes d'appui du talon au sol, selon qu'il s'agit de travailler l'équilibre, la résistance des chevilles, l'appui du pied au sol ...In the field of shoes, there is a demand to be able to change the appearance of a shoe, in particular a woman's shoe, by having the possibility of changing the shape or the material or the color of the heel of the shoe while keeping the same footwear. In addition, some shoes can be training or rehabilitation tools by offering the user different types of heel support on the ground, depending on whether it is a question of working the balance, the resistance of the ankles, the foot support ...
Des propositions de talon amovible pour offrir une possibilité d'interchangeabilité, ont déjà été faites de- puis de nombreuses années sans pour autant parvenir à une solution commerciale satisfaisante. En effet, les moyens permettant l'interchangeabilité ont toujours été compliqués et leur mise en œuvre fait souvent appel à un outillage que l'usager ne maîtrise pas bien. Dans le cas où le montage démontage du talon peut se faire à la main, la qualité de la liaison n'est pas suffisante pour que la chaussure soit utilisée de manière sûre. Dans d'autres cas enfin, les matériaux utilisés n'offrent pas de résistance suffisante pour un usage prolongé de la chaussure. Ces moyens connus ne sont pas plus satisfaisants pour ce qui concerne les chaussures à fonction technique qui sont sollicitées de manière encore plus sévère que les chaussures ordinaires.Proposals for a removable heel to provide interchangeability have already been made for many years without achieving a satisfactory commercial solution. Indeed, the means for interchangeability have always been complicated and their implementation often requires tools that the user does not control well. In the case where the mounting disassembly of the heel can be done by hand, the quality of the connection is not sufficient for the shoe to be used safely. In other cases, the materials used do not offer sufficient resistance for prolonged use of the shoe. These known means are not more satisfactory with regard to technical function shoes which are solicited even more severely than ordinary shoes.
Par la présente invention, on entend satisfaire correctement le besoin d'un talon interchangeable par une structure de ce talon et de la chaussure qui le reçoit apte à supporter les efforts importants que subit le talon lors du port de la chaussure.The present invention is intended to adequately satisfy the need for an interchangeable heel by a structure of the heel and the shoe that receives it able to withstand the significant efforts that the heel undergoes when wearing the shoe.
OBJET DE L'INVENTION La présente invention a pour objet une chaussure comportant une partie chaussante avec une partie arrière, une embase rapportée sous la partie arrière de la partie chaussante, un talon fixé de manière amovible à l'embase grâce à des moyens d'assemblage ajusté et un moyen de ver- rouillage automatique et déverrouillage manuel desdits moyens d'assemblage, caractérisé en ce que l'embase est en matière plastique qui comporte au moins trois inserts métalliques taraudés (écrous) pour recevoir trois vis de fixation de l'embase sous la partie arrière de la partie chaussante de la chaussure.OBJECT OF THE INVENTION The subject of the present invention is a boot comprising a footwear part with a rear part, a base attached under the rear part of the footwear part, a heel fixed removably to the base by means of fitted assembly and automatic locking means and manual unlocking of said assembly means, characterized in that the base is of plastics material which comprises at least three threaded metal inserts (nuts) for receiving three fastening screws of the base under the rear part of the footwear part of the shoe.
On a en effet constaté au cours de nombreux essais de résistance d'une telle chaussure, que c'est à l'endroit de la fixation de l'embase à la partie chaussante que les ruptures se produisent. L'état de la technique propose une fixation ordinaire au moyen de vis traversantes qui s'avèrent de résistance insuffisante compte tenu de la faible épaisseur de l'embase qui les reçoit. Cette faible épaisseur est en effet imposée par l'esthétique même de la chaussure afin qu'il n'y ait pas de solution de continuité trop apparente entre le talon et la chaussure.Indeed, it has been found in many resistance tests of such a shoe, that it is at the location of the attachment of the base to the footwear that the breaks occur. The state of the art proposes an ordinary fastening by means of through screws which prove to be of insufficient strength given the small thickness of the base which receives them. This small thickness is indeed imposed by the aesthetics of the shoe so that there is no solution too obvious continuity between the heel and the shoe.
De manière préférée, les inserts sont le plus éloignés possible les uns des autres et sont logés dans des surépaisseurs de l'embase, à l'extérieur des moyens d' assemblage. Le talon comporte des évidements pour loger lesdi- tes surépaisseurs lors de son assemblage avec l'embase.Preferably, the inserts are as far apart as possible and are housed in the thicknesses of the base, outside the assembly means. The heel has recesses for accommodating the said thicknesses during its assembly with the base.
Les moyens d'assemblage sont constitués par une queue d'aronde mâle en saillie de l'embase et une queue d'aronde femelle ménagée dans le talon. Les surépaisseurs dans lesquelles sont noyés les écrous sont disposées à l'extérieur de la queue d' aron.de mâle tandis que le talon comporte en correspondance des réserves pour le logement de ces surépaisseurs lors de l'emboîtement et l'assemblage des deux queues d'aronde. La partie périphérique visible de l'embase peut alors demeurer fine.The assembly means are constituted by a male dovetail protruding from the base and a female dovetail formed in the heel. The extra thicknesses in which the nuts are embedded are arranged to the outside of the tail of male aron.de while the heel has corresponding reserves for housing these extra thicknesses during the nesting and assembly of the two dovetails. The visible peripheral part of the base can then remain thin.
D'autres caractéristiques et avantages de l'invention ressortiront de la description donnée ci-après d'un exemple de réalisation de l'invention.Other features and advantages of the invention will emerge from the description given below of an exemplary embodiment of the invention.
BREVE DESCRIPTION DES DESSINS II sera fait référence aux dessins annexés parmi lesquels :BRIEF DESCRIPTION OF THE DRAWINGS Reference will be made to the accompanying drawings in which:
- la figure 1 est une vue en perspective de dessous de la partie arrière d'une chaussure selon l'invention,FIG. 1 is a perspective view from below of the rear part of a shoe according to the invention,
- la figure 2 est une vue en coupe selon le plan II-II de la figure 1, le talon et l'embase étant assemblés.- Figure 2 is a sectional view along the plane II-II of Figure 1, the heel and the base being assembled.
DESCRIPTION DETAILLEE DE L'INVENTION Aux figures, la chaussure selon l'invention comporte une partie chaussante 1 dont la partie arrière la est représentée. Cette partie chaussante comporte à sa base, de manière connue, une première de montage, une trépointe, un garnissage sur lequel est monté un cambrion et une semelle.DETAILED DESCRIPTION OF THE INVENTION In the figures, the boot according to the invention comprises a footwear part 1 whose rear part is shown. This footwear portion has at its base, in known manner, a first mounting, a welt, a lining on which is mounted a shank and a sole.
Sur cette base est rapportée une embase 2 servant de pièce d'assemblage amovible pour un talon 3. L'embase est une plaque mince sur sa périphérie en matériau synthé- tique (thermo plastique par exemple) qui possède le long de son axe longitudinal XX, qui correspond à la direction de la longueur de la chaussure, un tenon 4 en forme de queue d'aronde mâle, en saillie de la surface libre 2a de plaque mince. Au centre de ce tenon, une languette élastique 5, venue en une seule pièce avec le tenon, peut être élasti- quement effacée à l'intérieur d'un logement 6 du tenon par enfoncement en direction de la semelle d'une extrémité 5a de la languette qui dépasse du tenon en direction de la pointe de la chaussure. Dans sa position de repos, la sur- face visible 5b de la languette 5 est dans le même plan que la surface visible 4a de la queue d'aronde 4. Cette surface porte un ergot 7 qui fait donc saillie de ce plan lorsque la languette est au repos et qui est escamoté sous ce plan lorsque le languette 5 est effacée dans le logement 6 par action sur le poussoir 5a.On this base is reported a base 2 serving as a removable assembly part for a heel 3. The base is a thin plate on its periphery of synthetic material (thermoplastic for example) which has along its longitudinal axis XX , which corresponds to the direction of the length of the shoe, a pin 4 in the form of a male dovetail protruding from the free surface 2a of thin plate. In the center of this tenon, an elastic tongue 5, integral with the tenon, can be elastically erased inside a housing 6 of the tenon by driving towards the sole of an end 5a of the tongue that protrudes from the tenon towards the tip of the shoe. In its rest position, the visible surface 5b of the tongue 5 is in the same plane as the visible surface 4a of the dovetail 4. This surface carries a lug 7 which thus protrudes from this plane when the tongue is at rest and which is retracted under this plane when the tongue 5 is erased in the housing 6 by action on the pusher 5a.
A l'extérieur du tenon 4, la plaque mince comporte des surépaisseurs 8, 9 et 10, les deux premières étant situées à l'avant de l'embase en relation avec l'avant de la chaussure, de chaque côté du tenon 4 la troisième étant si- tuée à l'arrière de ce tenon, dans l'axe de ce dernier.Outside the tenon 4, the thin plate has extra thicknesses 8, 9 and 10, the first two being located at the front of the base in relation to the front of the shoe, on each side of the pin 4 la the third being located at the rear of this tenon, in the axis of the latter.
Chaque surépaisseur constitue le bloc de surmoulage pour un insert métallique 11, 12 et 13 qui est un écrou apte à recevoir des vis telles que 14 et 15 de la figure 2.Each overthickness constitutes the overmolding block for a metal insert 11, 12 and 13 which is a nut adapted to receive screws such as 14 and 15 of FIG.
Le talon 3 de la chaussure possède des moyens d'assemblage complémentaires à ceux de l'embase 2. Ils sont constitués par une queue d'aronde femelle 16, par un évide- ment 17 formé dans la base de cette queue d'aronde 16 et par des évidements 18, 19 et 20, situés à l'extérieur de la queue d'aronde femelle 16, dans une disposition relative identique à celle des surépaisseurs et tenon de l'embase 2.The heel 3 of the shoe has assembly means complementary to those of the base 2. They are constituted by a female dovetail 16, by a recess 17 formed in the base of this dovetail 16 and by recesses 18, 19 and 20, situated outside the female dovetail 16, in a relative arrangement identical to that of the extra thicknesses and tenon of the base 2.
L'embase est rapportée à la partie chaussante de la chaussure au moyen des vis 14 et 15 qui traverse la base de la partie arrière la de la chaussure comme illustré par la figure 2. Cette fixation est d'autant plus stable que les trois écrous 11, 12 et 13 sont éloignés les uns des autres. L'embase est fixée à demeure à la chaussure. Le talon est ensuite glissé sur l'embase selon la flèche F de la figure 1. Les queues d'aronde s'engagent l'une dans l'autre jusqu'au contact de l'ergot 7 avec le bord avant du talon. L'ergot possède avantageusement une pente qui permet d'éviter le blocage du mouvement d'engagement, lequel se poursuit en faisant fléchir la languette 5 à l'intérieur du logement 6. A la fin de l'engagement, l'ergot 7 vient se loger dans l'évidement 17 du talon par le retour élastique de la languette à sa position de repos. Le talon est alors verrouillé sur l'embase. L'ajustement de la fixation est serré par l'existence d'une contrainte de compression du talon entre les flancs inclinés de la queue d'aronde femelle et la surface supérieure 3a du talon, les dimensions de ce dernier ainsi que celles de l'embase étant prévues à l'effet de faire naître cette précontrainte au montage. Les surépaisseurs sont quant à elles de dimensions inférieures à celles des logements qui les accueillent de manière qu'il n'y ait aucune interférence entre elles et les moyens ac- tifs de l'assemblage.The base is attached to the foot part of the boot by means of the screws 14 and 15 which passes through the base of the rear part of the shoe as shown in FIG. 2. This binding is all the more stable as the three nuts 11, 12 and 13 are distant from each other. The base is permanently attached to the shoe. The heel is then slid on the base according to the arrow F of Figure 1. The dovetails engage one into the other until contact with the lug 7 with the front edge of the heel. The lug advantageously has a slope that avoids the blocking of the engagement movement, which continues by bending the tongue 5 inside the housing 6. At the end of the engagement, the lug 7 comes to lodge in the recess 17 of the heel by the elastic return of the tongue to its rest position. The heel is then locked on the base. The adjustment of the binding is tightened by the existence of a compressive stress of the heel between the inclined flanks of the female dovetail and the upper surface 3a of the heel, the dimensions of the latter as well as those of the base being provided for the purpose of giving rise to this prestressing assembly. The overthicknesses are smaller than those of the housing housing them so that there is no interference between them and the active means of assembly.
