The assembly has a removable sole element (11) fixed on an incomplete sole (1) of a ski shoe type rigid rod. The element has a hook (15) cooperating with a front part (2) of the sole, and is suitable to complete the incomplete sole so as to form a sole that is compatible with an ISO 5355standard of a ski shoe and an ISO 9253standard of a trail running shoe. A locking and fixation mechanism (3) locks the element under the incomplete sole, where the shoe is made of a plastic material.

Description

La présente invention concerne un ensemble chaussant du type chaussure de ski, respectant la norme ISO 5355 des chaussures de ski, adaptable à la pratique de la randonnée par une transformation de sa semelle, pour atteindre sensiblement la norme ISO 9523 des chaussures de randonnée.The present invention relates to a footwear type ski boot, meeting the ISO 5355 standard of ski boots, adaptable to the practice of hiking by a transformation of its sole, to substantially achieve the ISO 9523 standard of hiking shoes.

Le problème d'adapter une chaussure de ski à la marche s'est posé depuis très longtemps car le skieur a inévitablement des besoins de marcher avec ses chaussures de ski, que ce soit pour rejoindre le bas des remontées mécaniques depuis le parking ou son hôtel ou que ce soit pour atteindre un endroit en altitude non desservi par des remontées mécaniques.The problem of adapting a ski boot to walking has been a long time since the skier inevitably needs to walk with his ski boots, whether to reach the bottom of the lifts from the car park or hotel or to reach a place in altitude not served by lifts.

Une première solution, décrite dans le document US4811504 , prévoit une semelle de marche amovible qui s'adapte par-dessus une chaussure de ski normalisée. L'avantage de cette solution est d'offrir une chaussure de ski normalisée et donc par définition parfaitement adaptée à la pratique du ski. Son inconvénient est que la solution n'est pas performante pour la pratique de la marche.A first solution, described in the document US4811504 , provides a removable walking sole that fits over a standard ski boot. The advantage of this solution is to offer a standardized ski boot and therefore by definition perfectly adapted to the practice of skiing. Its disadvantage is that the solution is not effective for the practice of walking.

Une solution similaire est décrite aussi dans le document EP 0642748 .A similar solution is also described in the document EP 0642748 .

Une solution opposée est décrite dans le document US4542599 dans lequel une chaussure mieux adaptée à la marche est prévue, une semelle amovible s'ajoutant pour la pratique du ski. L'inconvénient de cette solution est toujours qu'elle ne permet pas d'obtenir une solution optimale pour la marche. De plus, la pratique du ski est peu sécurisée car la semelle amovible qui occupe toute la surface inférieure de la chaussure plus des rebords latéraux est difficile à fixer de manière satisfaisante et risque de se détacher lors des efforts subis par la pratique du ski.An opposite solution is described in the document US4542599 in which a shoe better adapted to walking is provided, a removable sole added to the practice of skiing. The disadvantage of this solution is that it does not provide an optimal solution for walking. In addition, the practice of skiing is not secure because the removable sole which occupies the entire lower surface of the shoe plus the side edges is difficult to fix satisfactorily and may become detached during the efforts suffered by skiing.

Un autre document FR2743700 de l'art antérieur divulgue une chaussure de sport pour engin de glisse qui peut être adaptée à la marche en prévoyant des moyens avant et arrière amovibles sous la semelle de la chaussure. Des plaques d'appui sont prévues latéralement sous la chaussure, aptes à coopérer avec des plaques complémentaires particulières d'une fixation de ski. Des glissières sont prévues sous la chaussure pour la fixation des parties amovibles. Aucun moyen de verrouillage des parties amovibles n'est décrit et des vis sont nécessaires pour leur maintien sous la chaussure. Un inconvénient de cette solution provient de son incompatibilité avec les normes existantes. En effet, elle exige des fixations de ski non normalisées avec des plaques d'appui spécifiques. Ce système s'avère de plus dangereux car peu efficace pour le déclenchement permettant la libération de la chaussure en cas de chute en torsion. De plus, lors de la pratique du ski, les parties amovibles coopèrent sur l'avant et l'arrière de la chaussure avec les mâchoires de la fixation de ski et subissent des efforts très importants qui entraînent une usure des glissières qui provoque l'apparition d'un jeu entre la partie amovible et la chaussure qui devient nuisible au bon guidage de l'engin de glisse. De même, cette solution ne permet pas d'atteindre une chaussure de marche se rapprochant des normes en vigueur. Enfin, elle nécessite aussi un outil pour les opérations de transformation de la chaussure, ce qui n'est pas convivial.Another document FR2743700 of the prior art discloses a sports shoe for gliding gear that can be adapted to walking by providing removable front and rear means under the sole of the shoe. Support plates are provided laterally under the boot, able to cooperate with particular complementary plates of a ski binding. Slides are provided under the shoe for fixing the removable parts. No means of locking the removable parts is described and screws are necessary for their maintenance under the shoe. A disadvantage of this solution stems from its incompatibility with existing standards. Indeed, it requires non-standardized ski bindings with specific support plates. This system proves more dangerous because it is not very effective for triggering allowing the release of the shoe in the event of a fall in torsion. In addition, during the practice of skiing, the removable parts cooperate on the front and rear of the shoe with the jaws of the ski binding and undergo very significant forces which cause wear sliding which causes the appearance a game between the removable part and the shoe that becomes harmful to the proper guidance of the gliding device. Similarly, this solution does not achieve a walking shoe approximating the standards in force. Finally, it also requires a tool for shoe processing operations, which is not user friendly.

Pour pallier aux inconvénients précédents, une solution différente est proposée dans le document FR2774266 qui permet une adaptation d'une chaussure de ski classique au ski de randonnée par exemple, sur la base d'une modification de la partie basse de la semelle uniquement. Des éléments de fixation comme des vis sont prévus pour maintenir les plaques amovibles sous la semelle. L'inconvénient de cette solution provient de sa non-convivialité puisque l'adaptation de la chaussure nécessite un outil. De plus, comme une petite partie de faible épaisseur est modifiée sous la chaussure, cette solution ne permet pas une adaptation profonde de la chaussure. En effet, les trottoirs conservent toujours les mêmes dimensions par exemple. Ainsi, cette approche ne permet pas une adaptation de la chaussure se rapprochant ou atteignant la norme des chaussures de randonnée.To overcome the above disadvantages, a different solution is proposed in the document FR2774266 which allows an adaptation of a classic ski boot to ski touring for example, on the basis of a modification of the lower part of the sole only. Fasteners such as screws are provided to hold the removable plates under the soleplate. The disadvantage of this solution comes from its non-usability since the adaptation of the shoe requires a tool. In addition, as a small thin portion is modified under the shoe, this solution does not allow a deep adaptation of the shoe. Indeed, sidewalks always keep the same dimensions for example. Thus, this approach does not allow an adaptation of the shoe approaching or reaching the standard of hiking shoes.

Enfin, il existe des solutions plus éloignées décrites dans les documents IT1220793 et IT1257619 qui prévoient des parties avant et arrière de semelles de chaussure de ski amovibles pour permettre leur adaptation à différentes pointures. Ces solutions nécessitent aussi des vis pour leur verrouillage, ce qui n'est pas convivial. Ces vis sont directement vissées dans le matériau plastique rigide positionné dans la semelle de la chaussure et ce dispositif n'est pas adapté à de nombreuses transformations car le plastique s'use très vite en devenant non opérationnel. De plus, elles ne divulguent pas l'adaptation de la chaussure à la marche.Finally, there are more distant solutions described in the documents IT1220793 and IT1257619 which provide for front and rear portions of removable ski boot soles to enable their adaptation to different sizes. These solutions also require screws for locking them, which is not user friendly. These screws are directly screwed into the rigid plastic material positioned in the sole of the shoe and this device is not suitable for many transformations because the plastic wears out very quickly becoming non-operational. In addition, they do not disclose the adaptation of the shoe to walking.

Aujourd'hui, des professionnels du ski, secouristes ou pisteurs par exemple, et des amateurs de la pratique du ski en haute montagne ont besoin d'accéder à des pentes non directement desservies par les remontées mécaniques classiques. Ils ont donc besoin de marcher en haute montagne pour y accéder, besoin qui exige une chaussure de marche performante, idéalement une chaussure de randonnée normalisée, dont la forme est naturellement optimisée pour la marche et permet de plus des adaptations particulières à l'aide d'accessoires, comme des crampons par exemple, qui ne sont compatibles qu'avec ces chaussures de randonnée normalisées. Ensuite, ces skieurs chaussent leurs skis et descendent sur des pentes bien souvent dangereuses. Ils ont donc aussi besoin d'une fixation de leur chaussure sur le ski très performante et sécurisée. Il s'avère que les fixations existantes de chaussures de randonnée sur un ski ne sont pas satisfaisantes. Ces skieurs ont en fait idéalement besoin d'une chaussure de ski normalisée associée à une fixation de ski alpin normalisée. Comme cela a été vu précédemment, aucune solution de l'art antérieur ne répond de manière satisfaisante à ce besoin.Today, ski professionals, first responders or trackers for example, and amateurs of skiing in the high mountains need access to slopes not directly served by conventional lifts. They therefore need to walk in the high mountains to access them, a need that requires a high-performance walking shoe, ideally a standardized hiking boot, whose shape is naturally optimized for walking and allows more specific adaptations using accessories, such as crampons for example, which are only compatible with these standard hiking boots. Then, these skiers put on their skis and descend on often dangerous slopes. they have so also need a fixation of their shoe on the ski very powerful and secure. It turns out that the existing bindings of hiking boots on a ski are not satisfactory. These skiers in fact ideally need a standardized ski boot associated with a standard alpine ski binding. As has been seen previously, no solution of the prior art satisfies this need satisfactorily.

Un objet général de l'invention consiste donc à prévoir un ensemble chaussant performant à !a fois pour la randonnée de haute montagne et la descente à ski, convivial et peu encombrant, évitant par exemple d'avoir deux paires de chaussures à transporter et deux paires de ski adaptées à chaque chaussure.A general object of the invention therefore consists in providing a high-performance footwear assembly both for high-altitude hiking and downhill skiing, which is user friendly and compact, for example avoiding two pairs of shoes to be carried and two pairs of ski adapted to each shoe.

Plus précisément, un premier objet de l'invention consiste donc en un ensemble chaussant suffisamment rigide pour une bonne transmission des efforts du skieur à une planche de glisse, et comprenant des trottoirs et des plaques d'appui normalisées, pour coopérer avec les fixations habituelles prévues sur les skis, et résistant aux forces subies dans des conditions extrêmes d'utilisation pour le ski.More precisely, a first object of the invention therefore consists of a footwear assembly that is sufficiently rigid for a good transmission of the skier's forces to a gliding board, and comprising sidewalks and standard bearing plates, to cooperate with the usual fasteners. provided on skis, and resistant to the forces under extreme conditions of use for skiing.

Un second objet de l'invention consiste en un ensemble chaussant qui permet la marche de type randonnée en haute montagne, offrant notamment un bon déroulé du pied et la possibilité éventuelle d'ajouter les accessoires normalisés comme des crampons.A second object of the invention consists of a set of footwear that allows trekking-type walking in the high mountains, including a good unwinding of the foot and the possible possibility of adding standardized accessories such as crampons.

Un troisième objet de l'invention consiste en un ensemble chaussant peu encombrant, pour lequel la transformation ski - marche est facile et conviviale, peut se pratiquer un grand nombre de fois sans entraîner une usure importante, quel que soit le lieu et les conditions extérieures.A third object of the invention consists of a compact footwear assembly, for which the ski-walking transformation is easy and user-friendly, can be practiced a large number of times without causing significant wear, regardless of the location and external conditions .

L'invention repose sur un ensemble chaussant comprenant une tige rigide de type chaussure de ski, sous laquelle se trouve une semelle incomplète apte à recevoir au moins une partie avant et/ou arrière de semelle amovible, qui peut être positionnée et verrouillée de manière mécanisée, sécurisée et sans outil spécifique, sous cette semelle incomplète de la tige afin de la compléter, la géométrie de la semelle incomplète de la tige rigide et des parties de semelle amovibles étant telles qu'il est possible de se conformer à la fois à la norme ISO 5355 des chaussures de ski et d'atteindre sensiblement les exigences de la norme ISO 9523 des chaussures de randonnée. La fixation de la semelle amovible avec le reste de la chaussure est telle qu'elle est aussi fiable et sécurisée que si elle était réalisée à l'aide de plusieurs vis, sans présenter l'inconvénient du vissage qui entraîne une usure rapide et n'est pas adapté à un grand nombre d'utilisations lors des démontages et remontages successifs.The invention is based on a footwear assembly comprising a rigid ski-boot-type upper, under which there is an incomplete soleplate able to receive at least one front and / or rear part of the removable soleplate, which can be positioned and locked in a mechanized manner. , secured and without a specific tool, under this incomplete sole of the rod to complete it, the geometry of the incomplete sole of the rigid rod and removable sole portions being such that it is possible to comply with both the ISO 5355 standard of ski boots and substantially meet the requirements of the ISO 9523 standard of hiking shoes. The fixation of the removable soleplate with the rest of the boot is such that it is as reliable and secure as if it were made with several screws, without the disadvantage of screwing which causes rapid wear and is not suitable for a large number of uses during successive disassembly and reassembly.

L'invention est plus précisément définie par les revendications.The invention is more precisely defined by the claims.

Le concept important de la solution proposée consiste à pouvoir obtenir, à partir d'une chaussure de ski normalisée, par une simple transformation sans outil particulier et sans altérer de façon importante certaines parties de la chaussure ou de la semelle, une modification sensible de la semelle de la chaussure pour la rendre compatible avec la norme ISO des chaussures de randonnée.The important concept of the proposed solution is to be able to obtain, from a standardized ski boot, a simple transformation without tools and without significantly altering certain parts of the shoe or the sole, a significant change in the sole of the shoe to make it compatible with the ISO standard of hiking shoes.

Pour rappel, la semelle normalisée des chaussures de randonnée est dans un matériau souple de type caoutchouc formant des crampons sous sa surface inférieure pour une bonne adhésion avec le sol, présente une forme antérieure arrondie pour permettre un bon déroulé du pied lors de la marche, et une hauteur de trottoir avant éloignée de celle d'une semelle de chaussure de ski normalisée, qui se trouve dans un matériau rigide pour une bonne liaison avec une fixation de ski et présente de plus une surface inférieure plate et lisse, avec des surfaces de glissement dites plaques d'appui nécessaires à la mise en oeuvre de la fonction de déclenchement consistant en la libération de sécurité de la chaussure de l'emprise d'une fixation de ski en cas de chute.As a reminder, the standardized sole of the hiking boots is made of a flexible rubber-like material forming crampons under its lower surface for good adhesion with the ground, has a rounded anterior shape to allow a good unwinding of the foot when walking, and a front sidewalk height remote from that of a standardized ski boot sole, which is in a rigid material for good bonding with a ski binding and further has a flat, smooth lower surface with sliding said support plates necessary for the implementation of the trigger function consisting of the safety release of the boot from the grip of a ski binding in case of a fall.

Un premier élément important de la solution est donc qu'elle permet une transformation sensible de la géométrie de la semelle de la chaussure, pour réaliser la transformation importante de la norme ISO des chaussures de ski vers celle des chaussures de randonnée, dont les différences sont importantes. Pour cela, la solution repose sur trois éléments principaux : une tige initiale ne comportant qu'une semelle incomplète et deux ensembles de semelles amovibles de géométrie différente pouvant se fixer et s'associer à ladite semelle incomplète pour former une chaussure opérationnelle possédant une configuration de semelle soit de chaussure de ski, soit de chaussure de randonnée. Selon la solution, les deux ensembles de semelles amovibles forment donc une partie non négligeable de la semelle finale obtenue, et forment notamment une partie importante, voire la totalité, des trottoirs avant et éventuellement arrière de la chaussure finalement obtenue.A first important element of the solution is that it allows a significant transformation of the geometry of the sole of the shoe, to achieve the important transformation of the ISO standard ski boots to that of hiking shoes, the differences are important. For this, the solution is based on three main elements: an initial stem having only one incomplete sole and two sets of removable geometry soles different being able to attach and associate with said incomplete sole to form an operational shoe having a sole configuration of either ski boot or hiking shoe. According to the solution, the two sets of removable soles thus form a significant part of the final sole obtained, and form in particular an important part, if not all, of the sidewalks before and possibly rear of the shoe finally obtained.

De plus, un second élément important du concept de l'invention provient du fait que cette transformation doit pouvoir se faire un grand nombre de fois, ce qui écarte par exemple toute solution qui comprendrait un vissage dans le matériau plastique de la chaussure elle-même puisqu'un tel vissage induit une usure rapide. Enfin, cette fixation des semelles amovibles doit être facile, rapide et sécurisée, afin de pouvoir être réalisée selon un montage automatique en toutes circonstances, en tout lieu et quelles que soient les conditions météorologiques par exemple, tout en obtenant un résultat qui garantit que les semelles amovibles rapportées ne vont pas se désolidariser de la chaussure dans une phase d'effort intense lors d'une marche ou d'une descente à ski.In addition, a second important element of the concept of the invention stems from the fact that this transformation must be able to be done a large number of times, which rules out for example any solution which would include a screwing in the plastic material of the shoe itself since such screwing induces rapid wear. Finally, this attachment of removable soles must be easy, fast and secure, so that it can be performed automatically in any circumstances, in any place and regardless of weather conditions for example, while obtaining a result that ensures that Removable soles reported will not separate from the shoe in a phase of intense effort during a walk or a ski descent.

Les modes d'exécution suivants illustrent à titre d'exemples des associations possibles d'une semelle amovible selon l'invention avec une semelle incomplète de tige de chaussure, et différents moyens de verrouillage sans vissage dans le matériau plastique lui-même de la chaussure et adaptés à de nombreuses utilisations.The following embodiments illustrate by way of examples possible combinations of a removable sole according to the invention with an incomplete sole of a shoe upper, and various means of locking without screwing into the plastic material itself of the shoe. and adapted for many uses.

Les figures 1 à 5 représentent un premier mode de réalisation de l'invention dans lequel une tige rigide partiellement représentée de type chaussure de ski comprend une semelle incomplète 1 sur laquelle peut être fixé un élément de semelle 11 amovible de manière à s'étendre sur une partie avant de la chaussure, suffisamment pour comprendre les éléments normalisés sous la semelle de la chaussure, comme les plaques d'appui pour les semelles de chaussure de ski.The Figures 1 to 5 represent a first embodiment of the invention in which a rigid rod partially represented ski boot type comprises an incomplete sole 1 on which can be attached a removable insole element 11 so as to extend over a front part of the shoe, enough to understand the standardized elements under the sole of the shoe, as the support plates for the ski boot soles.

Le principe d'accrochage de l'élément amovible 11 repose d'une part sur une coopération avec la partie avant 2 de la semelle incomplète 1 de la tige de chaussure et d'autre part sur une coopération avec un mécanisme de fixation et verrouillage 3 de la semelle incomplète 1 au niveau de l'arrière de l'élément amovible 11. Dans sa partie antérieure, l'élément amovible 11 comprend un trottoir 12 comprenant un rebord vertical intérieur 13 et des crochets 14 qui viennent en coopération avec des formes complémentaires à la surface frontale 2 de la semelle incomplète 1. Cette coopération est maintenue sous pression par le second moyen de fixation 3 des deux éléments 1, 11 disposé sous la chaussure. Ce second moyen de fixation 3 comprend des parties tronquées 4 réalisées dans une tige métallique 5 montée en rotation dans un espace 6 de la semelle incomplète 1 de la tige de la chaussure. L'axe 5 est maintenu dans son logement par un couvercle 7 et peut être mis en rotation manuellement, ou éventuellement à l'aide d'un élément rigide et fin comme une pièce de monnaie, par l'intermédiaire de ses extrémités latérales 8. Il peut occuper deux positions : une première position dans laquelle le méplat des parties tronquées 4 est vertical et permet de positionner ou d'enlever des crochets 15 de la semelle amovible 11 dans un emplacement 9 prévu dans la semelle 1, et une seconde position obtenue par une rotation d'un demi-tour de l'axe 5 en actionnant l'extrémité 8, dans laquelle la surface arrondie au niveau des parties tronquées 4 de l'axe 5 vient en appui contre des formes arrondies complémentaires des crochets 15 de la semelle amovible 11 pour les emprisonner dans leur logement 9 et verrouiller ainsi la semelle amovible 11. Sa libération est obtenue par une nouvelle rotation d'un demi-tour en sens inverse de l'axe 5, une tige 10 exerçant une poussée sous l'effet d'un ressort comprimé sur la partie extrême 16 de la semelle amovible 11 pour favoriser son désengagement. Comme cela est particulièrement illustré par les figures 3 et 4, l'élément amovible 11 représente une proportion très importante de la semelle finale composée, forme notamment l'intégralité du trottoir avant 12 de la chaussure ainsi montée. Cette solution permet ainsi d'imposer à la chaussure finalement montée la forme de sa semelle et donc la norme à respecter.The attachment principle of the removable element 11 rests on the one hand on a cooperation with the front portion 2 of the incomplete sole 1 of the boot upper and on the other hand on a cooperation with a fastening and locking mechanism 3 of the incomplete sole 1 at the rear of the removable element 11. In its front part, the removable element 11 comprises a sidewalk 12 comprising an inner vertical rim 13 and hooks 14 which come in cooperation with complementary shapes at the front surface 2 of the incomplete sole 1. This cooperation is maintained under pressure by the second attachment means 3 of the two elements 1, 11 disposed under the shoe. This second fixing means 3 comprises truncated portions 4 made in a metal rod 5 rotatably mounted in a space 6 of the incomplete sole 1 of the upper of the boot. The axis 5 is held in its housing by a cover 7 and can be rotated manually, or possibly by means of a rigid and thin element such as a coin, by means of its lateral ends 8. It can occupy two positions: a first position in which the flat portion of the truncated portions 4 is vertical and allows to position or remove hooks 15 of the removable soleplate 11 in a location 9 provided in the sole 1, and a second position obtained by a rotation of a half-turn of the axis 5 by actuating the end 8, in which the rounded surface at the truncated portions 4 of the axis 5 abuts against complementary rounded shapes of the hooks 15 of the Removable sole 11 to trap them in their housing 9 and thus lock the removable soleplate 11. Its release is obtained by a new rotation of a half-turn in the opposite direction of the axis 5, a rod 10 exerting a thrust under the effect of a compressed spring on the end portion 16 of the removable sole 11 to promote its disengagement. As is particularly illustrated by the Figures 3 and 4 , the removable element 11 represents a very large proportion of the compound final sole, including the entire shape of the front sidewalk 12 of the shoe thus mounted. This solution thus makes it possible to impose on the shoe finally mounted the shape of its sole and therefore the standard to be respected.

En remarque, la forme normalisée des parties arrières des deux semelles de chaussures de ski et de randonnée est très proche et le seul changement de la partie avant de la semelle permet d'atteindre sensiblement les deux normes. En variante, un autre élément de semelle amovible peut être prévu dans la partie arrière et fixé selon un dispositif de verrouillage similaire à celui décrit précédemment.As a note, the standardized shape of the rear parts of the two insoles of ski boots and hiking is very close and the only change of the front part of the sole makes it possible to substantially reach the two standards. Alternatively, another removable sole member may be provided in the rear portion and fixed according to a locking device similar to that described above.

Les figures 6 à 20 illustrent trois variantes d'un second mode de réalisation de l'invention dans lequel la semelle amovible s'étend sur sensiblement l'ensemble de la semelle incomplète de la tige de la chaussure, se composant d'une partie avant reliée à une partie arrière, les deux parties pouvant être verrouillées par un mécanisme de verrouillage positionné au niveau de la zone centrale sous la semelle incomplète de la tige de chaussure. Dans chacune de ces variantes, les parties avant et arrière de la semelle amovible coopèrent aussi avec les extrémités de la semelle incomplète de la tige, notamment pour former des trottoirs normalisés, selon l'une des normes au choix de chaussure de ski ou de randonnée.The Figures 6 to 20 illustrate three variants of a second embodiment of the invention in which the removable sole extends over substantially all of the incomplete sole of the upper of the shoe, consisting of a front part connected to a rear part. both parts being lockable by a locking mechanism positioned at the central area under the incomplete sole of the boot upper. In each of these variants, the front and rear portions of the removable sole also cooperate with the ends of the incomplete sole of the rod, in particular to form standardized sidewalks, according to one of the standards of the choice of ski boot or trekking .

Les figures 6 à 10 illustrent une première variante de réalisation d'une telle solution, dans laquelle la semelle amovible 31 se compose donc d'une semelle avant 32 reliée par des tiges 36 latérales à une semelle arrière 33. Chaque partie de semelle 32, 33 comprend vers ses extrémités des crochets 34, coopérant avec des parties complémentaires 27 de la semelle incomplète 21 de la chaussure, et dans sa partie centrale une gâche 35, apte à coopérer avec un dispositif de verrouillage 23 de la semelle incomplète 21 de la tige de chaussure, partiellement représentée sur les figures pour des raisons de clarté. Les tiges latérales 36 sont suffisamment flexibles pour permettre un léger rapprochement des deux parties de semelle 32, 33 pour le positionnement de la semelle amovible 31 dans sa position de fixation dans laquelle ses crochets 34 coopèrent avec les parties complémentaires 27 de la semelle incomplète 21 de chaussure. Cette dernière comprend à l'avant une partie de trottoir avant 22, à l'arrière une partie de trottoir arrière 26, des formes 27 à l'avant et à l'arrière complémentaires des crochets 34 et dans la zone centrale, un dispositif de verrouillage 23 de la semelle amovible 31. Ce dispositif de verrouillage 23 repose sur un plateau circulaire 25 monté en rotation et actionnable manuellement par un bouton 28 disposé sous sa surface inférieure et accessible entre les deux tiges latérales 36 reliant les deux parties 32, 33 de semelle amovible. Des pênes ou tiges de verrouillage longitudinales 24 diamétralement opposées sont fixées à la périphérie du plateau 25 et sont guidées de manière à rester sensiblement étendues dans la direction longitudinale de la chaussure. Le fonctionnement du verrouillage de la semelle amovible est plus précisément représenté sur les figures 8 à 10. Les deux parties complémentaires de semelle 21 et 31 sont approchées progressivement jusqu'à venir en contact, les pênes 24 étant dans une position d'ouverture, représentée sur la figure 9. Quand la semelle amovible est bien positionnée, une simple rotation d'un quart de tour du plateau circulaire 25 permet d'allonger les pênes 24 et de les amener dans leur configuration de verrouillage, illustrée sur la figure 10, dans laquelle ils prennent position dans les gâches 35 de la semelle amovible 31 en empêchant ainsi toute libération de la semelle.The Figures 6 to 10 illustrate a first variant embodiment of such a solution, in which the removable soleplate 31 therefore consists of a front sole 32 connected by lateral rods 36 to a rear sole 33. Each sole portion 32, 33 comprises, towards its ends, hooks 34, cooperating with complementary parts 27 of the incomplete sole 21 of the shoe, and in its central portion a keeper 35, adapted to cooperate with a locking device 23 of the incomplete sole 21 of the boot upper, partially shown in the figures for the sake of clarity. The lateral rods 36 are flexible enough to allow a slight approximation of the two sole portions 32, 33 for the positioning of the removable soleplate 31 in its fixing position in which its hooks 34 cooperate with the complementary parts 27 of the incomplete soleplate 21. shoe. The latter comprises at the front part of a curb before 22, at the rear part of a rear sidewalk 26, forms 27 at the front and at the back complementary to the hooks 34 and in the central zone, a device for locking 23 of the removable sole 31. This locking device 23 rests on a circular plate 25 rotatably mounted and manually operable by a button 28 disposed under its lower surface and accessible between the two lateral rods 36 connecting the two parts 32, 33 of removable insole. Diametrically opposite longitudinal locking bolts or rods 24 are fixed to the periphery of the plate 25 and are guided so as to remain substantially extended in the longitudinal direction of the boot. The operation of the locking of the removable base is more precisely represented on the Figures 8 to 10 . The two complementary sole parts 21 and 31 are gradually approached until they come into contact, the bolts 24 being in an open position, represented on the figure 9 . When the removable soleplate is correctly positioned, a simple rotation of a quarter turn of the circular plate 25 makes it possible to lengthen the bolts 24 and to bring them into their locking configuration, illustrated on FIG. figure 10 , in which they take position in the strikes 35 of the removable sole 31 thus preventing any release of the sole.

Dans une variante de réalisation, les extrémités des parties avant et arrière 32, 33 de la semelle amovible 31 peuvent avoir une forme différente, inclure par exemple l'intégralité des trottoirs avant et/ou arrière de manière similaire au premier mode de réalisation décrit précédemment. Dans cette variante, les tiges de liaison 36 entre les deux parties 32, 33 de semelle amovible 31 sont élastiques afin de pouvoir être allongées lors du positionnement de la semelle amovible 31 en appui sur les surfaces avant et arrière de la semelle incomplète 21 de la tige de chaussure.In an alternative embodiment, the ends of the front and rear portions 32, 33 of the removable sole 31 may have a different shape, for example include all the front and / or rear sidewalks similarly to the first embodiment described above. . In this variant, the connecting rods 36 between the two parts 32, 33 of the removable soleplate 31 are elastic so as to be elongate during the positioning of the removable soleplate 31 resting on the front and rear surfaces of the incomplete soleplate 21 of the shoe upper.

Les figures 11 à 17 illustrent une seconde variante de ce second mode de réalisation qui diffère principalement par son dispositif de verrouillage 23'. La semelle amovible se compose aussi de deux parties avant et arrière 32', 33', présentant chacune un prolongement 36'a, 36'b et un dispositif de verrouillage 23' directement aménagé sur ces prolongements. Ce dispositif de verrouillage 23' comprend un verrou 25' monté en rotation autour d'un axe 26' sur un prolongement 36'a, dont une partie 24' peut coopérer avec une marche ou dent 35' de l'autre extension centrale longitudinale 36'b, permettant ainsi de verrouiller l'écartement des deux éléments 32', 33' de la semelle amovible en prise avec les extrémités de la semelle incomplète 21' et d'empêcher leur mouvement longitudinal et leur libération.The Figures 11 to 17 illustrate a second variant of this second embodiment which differs mainly by its locking device 23 '. The removable sole is also composed of two front and rear portions 32 ', 33', each having an extension 36'a, 36'b and a locking device 23 'directly arranged on these extensions. This locking device 23 'comprises a latch 25' rotatably mounted about an axis 26 'on an extension 36'a, a part 24' of which can cooperate with a step or tooth 35 'of the other longitudinal central extension 36 'b, thus allowing to lock the spacing of the two elements 32', 33 'of the removable sole engaged with the ends of the incomplete sole 21' and to prevent their longitudinal movement and their release.

Cette variante de réalisation présente avantageusement un niveau de sécurité supplémentaire en ce qu'elle comprend un levier de sécurité 29', qui vient reposer sur la surface d'actionnement manuel 28' du verrou 25' dans sa position verrouillée, pour maintenir cette position de manière sécurisée. La figure 12 représente ainsi la semelle en configuration de verrouillage. Les figures 13 à 17 illustrent les différentes étapes de déverrouillage de la semelle amovible. L'utilisateur commence par actionner le levier de sécurité 29', avant de pouvoir actionner le verrou 25' en appuyant sur sa surface de commande 28', afin d'entraîner sa rotation autour d'un axe horizontal et transversal 26' et la libération de la dent 35' de l'extension 36'b, qui peut alors être retirée longitudinalement vers l'arrière.This variant of embodiment advantageously has an additional level of security in that it comprises a safety lever 29 ', which comes to rest on the manual actuating surface 28' of the lock 25 'in its locked position, to maintain this position of secure way. The figure 12 represents the sole in configuration of locking. The Figures 13 to 17 illustrate the different steps of unlocking the removable sole. The user starts by operating the safety lever 29 ', before being able to actuate the lock 25' by pressing on its control surface 28 ', to cause its rotation about a horizontal and transverse axis 26' and the release of the tooth 35 'of the extension 36'b, which can then be withdrawn longitudinally towards the rear.

Les figures 18 à 20 illustrent une troisième variante du second mode d'exécution de l'invention, dans laquelle la semelle amovible se compose toujours de deux parties avant et arrière 32", 33" comprenant respectivement des prolongements 36"a et 36"b sur lesquels est directement aménagé un moyen de verrouillage 23", comprenant d'une part une tige 25" montée sur un premier prolongement 36"a de manière mobile en translation transversale, actionnable par un bouton 28", et comprenant un anneau 24" pouvant coopérer avec une des dents circulaires 35" comprises au sein du second prolongement 36"b. La figure 19 illustre le dispositif dans une position verrouillée. Pour déverrouiller la semelle amovible, un utilisateur appuie manuellement sur le bouton 28" pour déplacer latéralement la tige 25" jusqu'à sortir l'anneau 24" de la dent 35" correspondante. Dans cette configuration, les extensions 36"a et 36"b peuvent se déplacer longitudinalement l'une par rapport à l'autre et la semelle rapportée 31" peut être ainsi enlevée. Le ressort de rappel 26" assure le retour de la tige 25" dans la configuration de verrouillage et évite les déverrouillages involontaires.The Figures 18 to 20 illustrate a third variant of the second embodiment of the invention, wherein the removable sole is always composed of two front and rear portions 32 ", 33" respectively comprising extensions 36 "a and 36" b on which is directly arranged a locking means 23 ", comprising on the one hand a rod 25" mounted on a first extension 36 "is movable in transverse translation, actuable by a button 28", and comprising a ring 24 "engageable with one of the teeth 35 "included in the second extension 36". figure 19 illustrates the device in a locked position. To unlock the removable sole, a user manually presses the button 28 "to laterally move the rod 25" to remove the ring 24 "of the corresponding tooth 35". In this configuration, the extensions 36 "a and 36" b can move longitudinally relative to each other and the insert sole 31 "can thus be removed.The return spring 26" ensures the return of the rod 25 "in the lockout configuration and avoids unintentional unlocking.

Les deux dernières variantes se distinguent des exécutions précédentes en ce que le moyen de verrouillage 23', 23" est directement monté sur les éléments de la semelle amovible, et non plus sur la semelle incomplète de la tige. De plus, ces deux solutions présentent un avantage supplémentaire d'offrir la possibilité du réglage de la longueur de la semelle amovible, grâce au réglage de l'écartement prévu entre les deux parties avant et arrière de semelle amovible qui peuvent être verrouillées selon différents écartements, ce qui la rend compatible avec des chaussures de pointure différente. Pour cela, plusieurs dents 35', 35" sont prévues dans chacune de ces variantes.The last two variants are distinguished from the previous embodiments in that the locking means 23 ', 23 "is directly mounted on the elements of the removable soleplate, and no longer on the incomplete soleplate of the rod. an advantage additional to offer the possibility of adjusting the length of the removable soleplate, through the adjustment of the spacing provided between the two front and rear removable soleplate that can be locked at different spacings, which makes it compatible with shoes different size. For this, several teeth 35 ', 35 "are provided in each of these variants.

Ces différentes solutions ont été présentées à titre d'exemples mais le concept de l'invention peut être mis en oeuvre avec d'autres configurations, notamment obtenues en combinant les différentes variantes de réalisation décrites précédemment. Par exemple, un moyen de sécurisation du moyen d'actionnement manuel en position verrouillée de la semelle, comme le levier 29' de la variante de réalisation illustrée sur les figures 11 à 17, peut aussi être implémenté sur toutes les autres variantes de réalisation.These different solutions have been presented as examples but the concept of the invention can be implemented with other configurations, in particular obtained by combining the various embodiments described above. For example, a means for securing the manual actuating means in the locked position of the soleplate, such as the lever 29 'of the embodiment variant illustrated in FIGS. Figures 11 to 17 , can also be implemented on all other variants.

Finalement, la solution atteint ainsi bien les objets recherchés et présente les avantages suivants :

  • même si un seul ensemble de semelle amovible 11, 31, 31' ou 31" a été représenté sur les figures pour des raisons de simplification, il est prévu deux ensembles de semelle amovible de géométrie différente mais aptes à une association avec la semelle incomplète 1, 21, 21', 21" de la tige rigide ;
  • ainsi, une chaussure de ski formée par l'utilisation d'un premier ensemble de semelle amovible peut être transformée à l'aide d'un second ensemble de semelle amovible de manière à obtenir une semelle sensiblement compatible avec la norme des chaussures de randonnée, ce qui permet une marche aisée et la fixation éventuelle sous la chaussure d'accessoires normalisés prévus pour les chaussures de randonnée, comme des crampons. Un même ensemble chaussant permet ainsi la pratique du ski en toute sécurité ainsi qu'une marche optimale ;
  • cette transformation de la semelle de ski en semelle de randonnée et inversement est simple et adaptée à un montage en tout lieu, même sans outil ;
  • un point commun des différentes solutions décrites est de permettre une transformation qui repose sur un moyen de fixation incluant un moyen de verrouillage adapté à de nombreuses utilisations, c'est à dire permettant un grand nombre d'opérations de transformation comme par exemple plusieurs transformations par jour d'utilisation de la chaussure, sans entraîner une usure importante des éléments de la chaussure. Cet effet technique nous permet de nommer cet élément essentiel de l'invention, en tenant compte de sa fonction technique, « moyen de verrouillage pour de nombreuses utilisations ». Impérativement, ce moyen de verrouillage pour de nombreuses utilisations ne comprend aucune opération de vissage au travers du matériau plastique de la chaussure. Un résultat obtenu par cet effet technique est de permettre d'avoir un ensemble chaussant peu encombrant dont l'utilisation est prévue pour une transformation à chaque changement montée - descente. Dans le cas d'une solution avec vissage, l'utilisateur choisit une option ski ou marche pour sa chaussure, qu'il conserve sur une longue période d'utilisation ;
  • la chaussure obtenue est sécurisée, la semelle est bien verrouillée et ne peut se libérer accidentellement. La fixation réalisée est aussi fiable et sécurisée qu'une fixation qui serait faite par un vissage des semelles amovibles.
Finally, the solution thus achieves the desired objects and has the following advantages:
  • even if a single removable sole assembly 11, 31, 31 'or 31 "has been shown in the figures for the sake of simplification, there are two sets of removable sole of different geometry but suitable for association with the incomplete sole 1 21, 21 ', 21 "of the rigid rod;
  • thus, a ski boot formed by the use of a first set of removable sole can be transformed using a second set of removable sole so as to obtain a sole substantially compatible with the standard of hiking shoes, which allows easy walking and the possible fixation under the shoe of standardized accessories provided for hiking shoes, like crampons. The same set of footwear allows the practice of skiing safely and optimal walking;
  • this transformation of the ski sole into a hiking sole and vice versa is simple and suitable for mounting anywhere, even without tools;
  • a common point of the various solutions described is to allow a transformation which is based on a fixing means including a locking means adapted to many uses, that is to say allowing a large number of processing operations such as several transformations by day of use of the shoe, without causing significant wear of the elements of the shoe. This technical effect allows us to name this essential element of the invention, taking into account its technical function, "locking means for many uses". Imperatively, this locking means for many uses does not include any screwing operation through the plastic material of the shoe. A result obtained by this technical effect is to allow a compact footwear assembly whose use is provided for a transformation at each change up - down. In the case of a solution with screwing, the user chooses a ski or walk option for his shoe, which he keeps for a long period of use;
  • the shoe obtained is secured, the sole is locked and can not be released accidentally. The fixation made is as reliable and secure as a fixation which would be made by screwing the removable soles.
