Description

Talon détachable à moyens magnétiques de fixation.Detachable heel with magnetic fastening means.

L'invention concerne le domaine des chaussures comprenant des talons amovibles, à montage et démontage répétitifs, sans outil.The invention relates to the field of footwear comprising removable heels, with repetitive assembly and disassembly, without tools.

Dans la publication ϋ.S. 3 977 095 (Philipps), il est indiqué la possibilité d'utiliser un accouplement magnétique par un aimant tubulaire et un noyau plongeur. Cet accouplement a pour but de modifier la hauteur du talon par une extension amovible sur un talon fixe. Le talon n'est donc pas amovible, et ne peut être changé tel qu'un talon jetable dès qu'il est abîmé, ou pour changer l'aspect décoratif extérieur du talon. Cette idée d'accouplement magnétique concerne donc un autre produit que le talon détachable, aux finalités différentes, ne visant pas la maintenance de l'esthétique du talon et de son changement de décoration.In the publication ϋ.S. 3 977 095 (Philipps), it is indicated the possibility of using a magnetic coupling by a tubular magnet and a plunger core. The purpose of this coupling is to modify the heel height by a removable extension on a fixed heel. The heel is therefore not removable, and cannot be changed such as a disposable heel as soon as it is damaged, or to change the exterior decorative appearance of the heel. This idea of magnetic coupling therefore concerns another product than the detachable heel, for different purposes, not aimed at maintaining the aesthetics of the heel and its change of decoration.

En outre, vouloir faire varier la hauteur d'un talon est illusoire pour un talon dépendant de la cambrure de la chaus¬ sure qui est rigidifiée par un cambrion. A chaque hauteur de talon correspond une cambrure spécifique. Dans ledit brevet, il est donc exprimé une idée qui ne peut rester qu'une idée puisqu'elle est inaplicable. Ce brevet ne peut donc absolu¬ ment pas être opposable à la présente demande de brevet en considération des motifs évoqués.In addition, wanting to vary the height of a heel is illusory for a heel depending on the camber of the shoe which is stiffened by a shank. Each heel height has a specific camber. In said patent, an idea is therefore expressed which can only remain an idea since it is inapplicable. This patent cannot therefore absolutely be relied on against this patent application in consideration of the reasons mentioned.

Dans l'invention du présent inventeur, FR.87-11548, il a été indiqué la possibilité d'utiliser un aimant pour la fixation d'un talon détachable, mais sans prendre en compte les diffi¬ cultés d'une telle utilisation applicable à une chaussure, et selon les résultats recherchés.In the invention of the present inventor, FR.87-11548, it was indicated the possibility of using a magnet for fixing a detachable heel, but without taking into account the diffi¬ culties of such use applicable to a shoe, and according to the desired results.

La présente invention a pour objet de préciser les moyens nécessaires et étudiés pour répondre aux dites difficultés.The object of the present invention is to specify the means necessary and studied to respond to said difficulties.

L'un des résultats recherchés est d'obtenir la même qualité de raccordement d'un telon détachable par rapport à un talon fixe, sans interstice avec la tige de la chaussure.One of the results sought is to obtain the same quality of connection of a detachable telon with respect to a heel. fixed, without gap with the upper of the shoe.

Cette recherche de qualité nécessite de compenser l'irrégula¬ rité et le manque de précision dans la réalisation de la par¬ tie de la chaussure sur laquelle sera monté le talon. Cette compensation est apportée par une technique d'ajustage auto¬ matique de l'application, sur ladite partie, du talon déta¬ chable.This search for quality requires compensating for the irregularity and the lack of precision in the production of the part of the shoe on which the heel will be mounted. This compensation is provided by an automatic adjustment technique of the application, on said part, of the detachable heel.

Un autre résultats recherché est d'amortir les chocs à chaque coup de talon sur le sol, et ainsi réduire les conséquences de ces chocs pouvant être transmis à un aimant rigide.Another sought-after result is to absorb the shocks with each heel kick on the ground, and thus reduce the consequences of these shocks which can be transmitted to a rigid magnet.

Plus précisément, et en fonction des résultats rechercchés, l'invention est exposée à l'aide de dessins décrits chrono¬ logiquement.More specifically, and depending on the desired results, the invention is explained using drawings described chrono¬ logically.

La figure 1 est une vue partielle, de côté et en coupe, repré- sentant une semelle de chaussure et un talon haut détachable sans outil. La semelle 1 est solidaire d'un support de talons formé d'une partie conique 2 moulée sur un insert métallique 3. Le talon i+ est fixé audit support par un moyen permettant: une fixation magnétique, un amortissement des chocs, et un ajustement automatique de la pénétration du talon. Ce moyen est formé par la combinaison d'un aimant 5 et d'une masse plastique déformable à la compression dudit talon. Selon une forme de réalisation, l'aimant 5 est composé d'une poudre magnétique dispersée dans un élastomère et venant au contact d'une bague métallique 6 coulissant à force dans un lamage au sommet de l'alésage du talon. L'insert métallique 3 est intro¬ duit, sans serrage, dans ledit alésage. Nous aurons donc un amortissement des chocs par 1'élastomère, et un ajustement axial par la bague métallique s'enfonçant dans le talon lors de son montage sur le support 2, 3» Les lignes de champs ma¬ gnétique sont canalisées par la bague métallique 6 comprenant une bordure périphérique entourant l'aimant annulaire 5. et elles sont canalisées par une plaque métallique arrière au contact de ladite bordure. Ladite plaque arrière n'apparaît pas, elle est comprise globalement dans la représentation de la masse magnétique 5 de forme annulaire. L'insert métallique 3, en position axiale, forme un pôle central au contact de la matière plastique, amagnétique, enrobant l'aimant, et au con- tact des dites pièces métalliques, incluant la bague 6, cana¬ lisant les lignes de champs magnétique. En outre, le talon détachable comprend une proéminence intérieure 7 s'engageant dans une entaille 8 de son support 2, pour stabiliser sa posi¬ tion angulaire relativement à l'axe longitudinal de la semel- le 1.FIG. 1 is a partial view, from the side and in section, showing a shoe sole and a detachable high heel without tools. The sole 1 is secured to a heel support formed by a conical part 2 molded on a metal insert 3. The heel i + is fixed to said support by a means allowing: magnetic fixing, shock absorption, and automatic adjustment heel penetration. This means is formed by the combination of a magnet 5 and a plastic mass deformable upon compression of said heel. According to one embodiment, the magnet 5 is composed of a magnetic powder dispersed in an elastomer and coming into contact with a metal ring 6 sliding by force in a countersink at the top of the heel bore. The metal insert 3 is inserted, without tightening, into said bore. We will therefore have shock absorption by the elastomer, and an axial adjustment by the metal ring sinking into the heel when it is mounted on the support 2, 3 "The magnetic field lines are channeled by the metal ring 6 comprising a peripheral border surrounding the annular magnet 5 . and they are channeled by a rear metal plate in contact with said border. Said backplate does not appear not, it is generally understood in the representation of the magnetic mass 5 of annular shape. The metal insert 3, in axial position, forms a central pole in contact with the plastic, non-magnetic material, coating the magnet, and in contact with said metal parts, including the ring 6, cana¬ reading the field lines magnetic. In addition, the detachable heel includes an inner prominence 7 engaging in a notch 8 of its support 2, to stabilize its angular position relative to the longitudinal axis of the sole 1.

La figure 2 est une vue similaire à la fig.1, mais représen¬ tant une conception différente de fixation magnétique pour amortir les chocs et ajuster automatiquement la pénétration du talon qui pourra s'appliquer sans interstice contre la partie de la chaussure incluant le support 2. Pour cette fixa¬ tion simplifiée, 1'insert métallique 3 est utilisé comme noyau plongeant dans un aimant tubulaire 9 immobilisé dans le talon .+. Ainsi, les lignes de force magnétique de l'aimant attirent le noyau 3 dans le talon, lequel par réaction, se déplace pour venir buter contre ladite partie de la chaussure, de manière à obtenir une même qualité de raccordement qu'un talon fixe.Figure 2 is a view similar to fig.1, but as a different design of magnetic fastening to absorb shock and automatically adjust the penetration of the heel which can be applied without gaps against the part of the shoe including the support 2. For this simplified fixing, the metal insert 3 is used as a plunging core in a tubular magnet 9 immobilized in the heel. +. Thus, the magnetic force lines of the magnet attract the core 3 in the heel, which by reaction moves to abut against said part of the shoe, so as to obtain the same quality of connection as a fixed heel.

La figure 3 est une vue similaire aux fig.1 et 2, mais repré¬ sentant une disposition différente dans l'association de 1'insert métallique 3 avec une masse magnétique 10. Dans cet¬ te disposition, 1'insert métallique 3 est creux pour contenir axialement un aimant cylindrique 10 enrobé au moins sur sa surface latérale d'une matière amagnétique 11 comprenant des arêtes dorsales s'écrasant au montage à force dans ledit in- sert. Le talon 4 comprend une coupelle métallique 12 venant au contact de 1'insert 3 lors de l'assemblage du talon sur son support 2. L'alésage du talon comprend des arêtes longi¬ tudinales qui sont écrasées lors de l'enfoncement de la cou¬ pelle 12. FIG. 3 is a view similar to FIGS. 1 and 2, but representing a different arrangement in the association of the metal insert 3 with a magnetic mass 10. In this arrangement, the metal insert 3 is hollow for axially containing a cylindrical magnet 10 coated at least on its lateral surface with a non-magnetic material 11 comprising dorsal ridges which can be crushed when mounted by force in said insert. The heel 4 comprises a metal cup 12 coming into contact with the insert 3 during the assembly of the heel on its support 2. The bore of the heel comprises longi¬ tudinal ridges which are crushed when the neck is pushed in ¬ shovel 12.
