Description

L'invention se rapporte à un dispositif de retenue d'une chaussure sur un engin de sport, dispositif qui comprend un mécanisme de verrouillage réversible d'un élément d'ancrage de la chaussure.The invention relates to a device for retaining a shoe on a sports machine, which device comprises a reversible locking mechanism of an anchoring element of the boot.

Un tel dispositif est employé dans des domaines comme le ski, particulièrement le ski de fond, de randonnée, ou de télémark, la raquette à neige, le ski ou le patin à roues, ou autre.Such a device is used in areas such as skiing, particularly cross-country skiing, hiking, or telemark, snowshoeing, skiing or rollerblading, or the like.

Dans un dispositif de retenue il est connu de faire appel à un mécanisme de verrouillage réversible qui comprend un carter qui porte une mâchoire fixe, une embase, et un tiroir qui porte une mâchoire mobile. Bien entendu le tiroir peut coulisser dans le carter dans un sens de rapprochement ou dans un sens d'éloignement relatif des mâchoires, le coulissement étant obtenu en partie au moins par action sur un levier du mécanisme.In a retainer it is known to use a reversible locking mechanism which comprises a housing which carries a fixed jaw, a base, and a drawer which carries a movable jaw. Of course the slide can slide in the housing in a direction of approximation or in a direction of relative distance of the jaws, the sliding being obtained in part at least by action on a lever of the mechanism.

Un tel agencement est révélé par exemple dans le document FR2638 974 , pour une application au ski de fond. Selon ce document, la mise en oeuvre du mécanisme, c'est-à-dire l'action qui permet de verrouiller ou de déverrouiller en déplaçant le tiroir, est faite par un système à genouillère. De manière connue ce système comprend deux bras et trois articulations, dont l'une relie les bras l'un à l'autre. C'est la position relative des bras et des axes d'articulation qui maintient le tiroir en position verrouillée stable ou, inversement, en position déverrouillée. Ce système présente l'avantage d'être fiable, dans le sens où il est solide, résistant à l'usure, et opérationnel dans des circonstances difficiles comme celles liées au froid ou à la présence de neige. Il donne donc satisfaction à un utilisateur. Cependant ce système présente quelques inconvénients. Notamment, il est relativement complexe, dans le sens où il comporte un nombre: significatif de pièces comme les bras et les articulations. Par corollaire d'autres inconvénients apparaissent, comme le temps nécessaire à l'assemblage et le coût de fabrication. Ces facteurs augmentent en proportion à la complexité.Such an arrangement is disclosed for example in the document FR2638974 , for an application to cross-country skiing. According to this document, the implementation of the mechanism, that is to say the action that allows to lock or unlock by moving the drawer, is made by a toggle system. In known manner this system comprises two arms and three joints, one of which connects the arms to one another. It is the relative position of the arms and hinge pins that keeps the drawer in the locked stable position or, conversely, in the unlocked position. This system has the advantage of being reliable, in the sense that it is solid, resistant to wear, and operational in difficult circumstances such as those related to cold or the presence of snow. It gives satisfaction to a user. However this system has some disadvantages. In particular, it is relatively complex, in the sense that it comprises a significant number of parts such as arms and joints. By corollary other disadvantages appear, such as the time required for assembly and the cost of manufacture. These factors increase in proportion to the complexity.

Etant donné que le système à genouillère fait partie du mécanisme de verrouillage réversible, on peut dire que le dispositif de retenue selon le document FR 2 638 974 présente, comme inconvénients, une certaine complexité, une durée de fabrication excessive, et un prix de revient relativement élevé.Since the toggle system is part of the reversible locking mechanism, it can be said that the retainer according to the document FR 2,638,974 presents, as disadvantages, a certain complexity, an excessive manufacturing time, and a relatively high cost price.

Par rapport à cela l'invention pour objectif général d'améliorer un dispositif de retenue qui comprend un mécanisme de verrouillage réversible d'un élément d'ancrage d'une chaussure. Plus précisément un but de l'invention est de simplifier la structure du mécanisme de verrouillage. Un autre but est de réduire la durée d'assemblage des pièces constitutives du mécanisme. Un but encore est de réduire le coût de fabrication du mécanisme.With respect to this, the invention generally aims to improve a retaining device which comprises a reversible locking mechanism of an anchoring element of a boot. More specifically, an object of the invention is to simplify the structure of the locking mechanism. Another aim is to reduce the assembly time of the component parts of the mechanism. One more goal is to reduce the manufacturing cost of the mechanism.

Pour ce faire l'invention propose un dispositif de retenue d'une chaussure sur un engin de sport, le dispositif comprenant un mécanisme de verrouillage réversible d'un élément d'ancrage de la chaussure, le mécanisme comprenant un carter qui porte une mâchoire fixe, une embase, et un tiroir qui porte une mâchoire mobile, le tiroir pouvant coulisser dans le carter dans un sens de rapprochement ou dans un sens d'éloignement relatif des mâchoires, le mécanisme comprenant encore un levier. Le levier présente une surface de came, le levier étant solidarisé par une articulation à l'une des pièces que sont le carter et le tiroir, l'autre des pièces présentant une surface d'appui, les surfaces de came et d'appui coopérant de façon que, lorsqu'elles sont en contact l'une avec l'autre, les mâchoires sont rapprochées l'une de l'autre si le levier est dans une position de verrouillage, et les mâchoires sont éloignées l'une de l'autre si le levier est dans une position de déverrouillage.To do this, the invention proposes a device for retaining a boot on a sports machine, the device comprising a reversible locking mechanism of an anchoring element of the boot, the mechanism comprising a casing which carries a fixed jaw. , a base, and a drawer which carries a movable jaw, the slide slidable in the housing in a direction of approach or in a direction of relative distance from the jaws, the mechanism further comprising a lever. The lever has a cam surface, the lever being secured by a hinge to one of the parts that are the housing and the drawer, the other of the parts having a bearing surface, the cam surfaces and bearing cooperating so that, when in contact with each other, the jaws are brought closer to each other if the lever is in a locking position, and the jaws are moved away from one another other if the lever is in an unlock position.

Le dispositif de retenue selon l'invention est caractérisé par le fait que le mécanisme comprend un moyen élastique apte à solliciter le tiroir de manière à provoquer le déplacement relatif de la mâchoire mobile par rapport à la mâchoire fixe.The retaining device according to the invention is characterized in that the mechanism comprises an elastic means adapted to bias the slide so as to cause the relative movement of the movable jaw with respect to the fixed jaw.

En fait l'agencement du mécanisme de verrouillage organise une coopération entre la position du levier et la position du tiroir. Cette coopération se fait par contact entre la surface de came du levier et la surface d'appui liée soit au carter soit au tiroir. Le contact est direct, ce qui revient à dire qu'il se fait sans recours à d'autres pièces mobiles.In fact the arrangement of the locking mechanism organizes a cooperation between the position of the lever and the position of the drawer. This cooperation is done by contact between the cam surface of the lever and the bearing surface connected to either the housing or the drawer. The contact is direct, which is to say that it is done without recourse to other moving parts.

Un premier avantage généré par l'invention est celui de la simplicité, non seulement en ce qui concerne la structure du mécanisme de verrouillage, mais aussi en ce qui concerne son utilisation. En effet, le frottement relatif des surfaces de came et d'appui renseigne fidèlement l'utilisateur sur l'état du mécanisme, c'est-à-dire sur la position de la mâchoire mobile, car les efforts liés au verrouillage sont transmis directement entre le levier et le tiroir par l'interaction des surfaces de came et d'appui.A first advantage generated by the invention is that of simplicity, not only as regards the structure of the locking mechanism, but also with regard to its use. Indeed, the relative friction of the cam and bearing surfaces faithfully informs the user about the state of the mechanism, that is to say on the position of the movable jaw, because the lock-related efforts are transmitted directly. between the lever and the drawer by the interaction of cam and support surfaces.

D'autres avantages obtenus par l'invention sont notamment une réduction de la durée d'assemblage des pièces constitutives du mécanisme, ou la réduction du coût do fabrication du mécanisme.Other advantages obtained by the invention include a reduction in the assembly time of the component parts of the mechanism, or the reduction of the manufacturing cost of the mechanism.

La première forme de réalisation qui va être décrite après concerne plus spécialement un dispositif de retenue d'une chaussure sur un ski de fond, ou de télémark. Cependant l'invention s'applique à d'autres domaines, tels que ceux évoqués avant.The first embodiment which will be described below relates more particularly to a device for retaining a boot on a cross-country ski, or telemark. However, the invention applies to other fields, such as those mentioned before.

La première forme est décrite ci-après à l'aide des figures 1 à 5.The first form is described below using the Figures 1 to 5 .

Comme on le comprend à l'aide de l'ensemble des figures, un dispositif de retenue 1 est prévu pour retenir de manière réversible une chaussure 2 sur un ski de fond 3. Pour des raisons de commodité, la chaussure 2 est représentée en partie seulement, en traits mixtes. On remarque qu'elle 2 comprend un élément d'ancrage 4, élément réalisé par exemple à l'aide d'un fil rigide de section circulaire, orienté transversalement et parallèlement au semelage 5.As can be understood from all the figures, a retaining device 1 is provided for reversibly retaining a shoe 2 on a cross-country ski 3. For reasons of convenience, the shoe 2 is represented in part only, in phantom. It will be noted that it comprises an anchoring element 4, made for example by means of a rigid wire of circular section, oriented transversely and parallel to the soleing 5.

Toujours pour des raisons de commodité, le ski 3 est représenté de manière partielle et stylisée. Il 3 est bien connu de l'homme du métier.Still for the sake of convenience, the ski 3 is shown partially and stylized. It is well known to those skilled in the art.

Sur les figures 1 et 2, on observe que le dispositif de retenue 1 comprend un premier mécanisme de verrouillage réversible 6 de l'élément d'ancrage 4 de la chaussure 2. Le fonctionnement du mécanisme 6 sera abordé après. On note que le dispositif de retenue 1 comprend, tel que montré sur les figures, seulement le premier mécanisme de verrouillage réversible 6. Il faut être conscient cependant que le dispositif 1 peut comprendre aussi un deuxième mécanisme, non représenté, qui peut être lui aussi un mécanisme de verrouillage réversible, un mécanisme de rappel élastique, ou encore un mécanisme qui assure à la fois les fonctions de verrouillage et de rappel. Le deuxième mécanisme coopère dans ce cas avec un autre élément d'ancrage de la chaussure, situé plus en arrière que celui 4 utilisé pour coopérer avec le premier mécanisme de verrouillage réversible 6. Le dispositif 1 peut comprendre encore une ou plusieurs arêtes de guidage longitudinal du semelage 5.On the Figures 1 and 2 , it is observed that the retaining device 1 comprises a first reversible locking mechanism 6 of the anchoring element 4 of the shoe 2. The operation of the mechanism 6 will be discussed later. Note that the retaining device 1 comprises, as shown in the figures, only the first reversible locking mechanism 6. It should be understood, however, that the device 1 may also include a second mechanism, not shown, which may also be a reversible locking mechanism, an elastic return mechanism, or a mechanism that provides both the locking and return functions. The second mechanism cooperates in this case with another anchoring element of the shoe, located further back than that 4 used to cooperate with the first reversible locking mechanism 6. The device 1 may further comprise one or more longitudinal guide edges of the sole assembly 5.

Quel que soit le nombre de sous-ensembles prévu pour constituer le dispositif de retenue 1, le premier mécanisme de verrouillage 6, appelé simplement mécanisme de verrouillage réversible 6, comprend notamment un carter 11, qui porte une mâchoire fixe 12, une embase 13, et un tiroir 14, qui porte une mâchoire mobile 15. On verra mieux par la suite comment ces éléments 11, 12, 13, 14 et 15 sont structurés et comment ils fonctionnent.Whatever the number of subassemblies intended to constitute the retaining device 1, the first locking mechanism 6, called simply reversible locking mechanism 6, comprises in particular a casing 11, which carries a fixed jaw 12, a base 13, and a drawer 14, which carries a movable jaw 15. It will be seen later how these elements 11, 12, 13, 14 and 15 are structured and how they work.

Le dispositif de retenue 1, en fait ici le mécanisme de verrouillage 6, comprend encore un levier 16. Ce dernier sert à verrouiller ou à déverrouiller le mécanisme, par exemple par une action extérieure telle qu'une action manuelle. Là encore la structure et le fonctionnement du levier 16 seront approfondis après.The retaining device 1, here in fact the locking mechanism 6, further comprises a lever 16. The latter serves to lock or unlock the mechanism, for example by an external action such as a manual action. Here again the structure and operation of the lever 16 will be deepened afterwards.

Selon l'invention, comme on peut le voir sur les figures 3 à 5, le levier 16 présente une surface de came 21, le levier 16 étant solidarisé par une articulation 22 à l'une des pièces que sont le carter 11 et le tiroir 14, l'autre des pièces 11, 14 présentant une surface d'appui 23, les surfaces de came 21 et d'appui 23 coopérant de façon que, lorsqu'elles sont en contact l'une avec l'autre, les mâchoires fixe 12 et mobile 15 sont rapprochées l'une de l'autre si le levier 16 est dans une position do verrouillage, et les mâchoires fixe 12 et mobile 15 sont éloignées l'une de l'autre si le levier 16 est dans une position de déverrouillage.According to the invention, as can be seen on the Figures 3 to 5 , the lever 16 has a cam surface 21, the lever 16 being secured by a hinge 22 to one of the parts that are the housing 11 and the slide 14, the other of the parts 11, 14 having a bearing surface 23, the cam surfaces 21 and support 23 cooperating so that, when in contact with each other, the fixed jaws 12 and movable 15 are moved towards each other if the lever 16 is in a locking position, and the fixed and movable jaws 12 are moved away from each other if the lever 16 is in an unlocked position.

Le levier 16 agit directement sur le carter 11 ou sur le tiroir 14 par contact des surfaces de came 21 et d'appui 23. Cette action directe permet à l'utilisateur de bien percevoir la position du tiroir, et donc de la mâchoire mobile 15, lorsqu'il manipule le levier 16. De plus, par la simplicité de sa structure, le mécanisme de verrouillage 6 transmet fidèlement les impulsions de conduite, ou les informations sensorielles, entre la chaussure 2 et le ski 3.The lever 16 acts directly on the housing 11 or on the slide 14 by contacting the cam surfaces 21 and support 23. This direct action allows the user to properly perceive the position of the drawer, and therefore the movable jaw 15 when the lever 16 is manipulated. Moreover, because of the simplicity of its structure, the locking mechanism 6 faithfully transmits driving pulses, or sensory information, between the boot 2 and the ski 3.

De manière non limitative selon la première forme de réalisation de l'invention, comme on le perçoit à l'aide de l'ensemble des figures 1 à 5, le carter 11 délimite une cavité longitudinale 24. Pour ce faire le carter 11 comprend une première paroi latérale 25 opposée à une deuxième paroi latérale 26, lesquelles 25, 26 sont reliées l'une à l'autre par un dessus 27 et une paroi arrière 28. Les parois 25, 26, 28 et le dessus 27 forment ici une pièce monobloc. En complément, un couvercle 29 délimite la cavité 24 à l'opposé du dessus 27. On remarque que ce dernier 27 est prévu pour être en vis-à-vis de la chaussure 2, et que le couvercle 29 est tourné vers le ski 3.In a nonlimiting manner according to the first embodiment of the invention, as can be seen using all of the Figures 1 to 5 , the housing 11 delimits a longitudinal cavity 24. To do this, the casing 11 comprises a first lateral wall 25 opposite a second lateral wall 26, which 25, 26 are connected to one another by a top 27 and a wall 28. The walls 25, 26, 28 and the top 27 form here a single piece. In addition, a cover 29 delimits the cavity 24 opposite the top 27. It is noted that the latter 27 is provided to be opposite the shoe 2, and that the lid 29 is facing the ski 3 .

Le carter 11 est solidarisé à l'embase 13, par les parois latérale 25, 26 et arrière 28. En fait ici l'embase 13 et le carter 11 forment une pièce monobloc. Par corollaire le couvercle 29 est parallèle à l'embase 13, et par exemple situé dans un même plan que celle-ci 13. L'embase 13 est réalisée sous la forme d'une plaque qui s'étend à la base du carter 11, notamment vers l'avant, c'est-à-dire dans un sens d'éloignement de la paroi arrière 28, mais aussi sur les côtés.The housing 11 is secured to the base 13, by the side walls 25, 26 and rear 28. In fact here the base 13 and the housing 11 form a single piece. By corollary the cover 29 is parallel to the base 13, and for example located in the same plane as the latter 13. The base 13 is formed as a plate which extends to the base of the housing 11 , especially towards the front, that is to say in a direction away from the rear wall 28, but also on the sides.

Le tiroir 14, logé dans le carter 11, est mobile en translation parallèlement à l'embase 13. Etant donné que cette dernière 13 est prévue pour prendre appui sur le ski 3, directement ou indirectement, le tiroir 14 est lui-même mobile en translation dans le sens de la longueur du ski 3. Il s'ensuit que la mâchoire 15 est mobile en translation, parallèlement à l'embase 13, dans le sens de la longueur du ski 3, lorsque le mécanisme 6 est monté sur ce dernier 3. Cela favorise une coopération avec l'élément d'ancrage transversal 4 de la chaussure 2.The slide 14, housed in the housing 11, is movable in translation parallel to the base 13. Since the latter 13 is provided to bear on the ski 3, directly or indirectly, the slide 14 is itself movable in translation in the direction of the length of the ski 3. It follows that the jaw 15 is movable in translation, parallel to the base 13, in the direction of the length of the ski 3, when the mechanism 6 is mounted on the latter 3. This promotes cooperation with the transverse anchoring element 4 of the shoe 2.

Selon la première forme de réalisation de l'invention, le levier 16 est solidarisé au tiroir 14. En conséquence le levier 16 suit les déplacements du tiroir 14, aussi bien dans un sens de verrouillage que dans un sens de déverrouillage.According to the first embodiment of the invention, the lever 16 is secured to the slide 14. As a result the lever 16 follows the movements of the slide 14, both in a locking direction and in an unlocking direction.

Le levier 16 s'étend en longueur entre une extrémité d'articulation 33 et une extrémité libre 34. L'articulation 22 solidarise l'extrémité d'articulation 33 du levier 16 au tiroir 14. L'articulation 22 comprend par exemple un tourillon qui s'étend selon un axe 35. L'extrémité libre 34, quant à elle, est destinée à être manipulée par l'utilisateur, comme on le verra mieux après.The lever 16 extends in length between a hinge end 33 and a free end 34. The hinge 22 secures the hinge end 33 of the lever 16 to the drawer 14. The hinge 22 comprises for example a journal which extends along an axis 35. The free end 34, for its part, is intended to be manipulated by the user, as will be seen later.

L'axe 35 de l'articulation 22 du levier 16 est parallèle à l'embase 13. Cela permet la manipulation de l'extrémité libre 34 dans un sens d'éloignement ou dans un sens de rapprochement de l'embase 13 c'est-à-dire aussi, par relation de cause à effet, du ski 3. Cette manipulation a l'avantage d'être simple à réaliser.The axis 35 of the articulation 22 of the lever 16 is parallel to the base 13. This allows the manipulation of the free end 34 in a direction of removal or in a direction of approximation of the base 13 is that is to say also, by cause-effect relationship, ski 3. This manipulation has the advantage of being simple to achieve.

De manière non limitative l'axe 35 de l'articulation 22 du levier 16 est perpendiculaire au sens de déplacement du tiroir 14 dans le carter 11. Il s'ensuit que le levier 16 pivote dans un plan perpendiculaire à l'embase 13 ou au ski 3. Le levier 16 reste donc au-dessus de l'embase 13 et du ski, ce qui gatantit l'absence d'interférence par contact avec un autre dispositif de retenue utilisé pour le deuxième pied, ou avec tout autre obstacle. L'utilisation du dispositif 1 est donc plus facile.Without limitation, the axis 35 of the hinge 22 of the lever 16 is perpendicular to the direction of movement of the slide 14 in the housing 11. It follows that the lever 16 pivots in a plane perpendicular to the base 13 or the ski 3. The lever 16 thus remains above the base 13 and the ski, which gatantit the absence of interference by contact with another retaining device used for the second foot, or with any other obstacle. The use of the device 1 is therefore easier.

La surface de came 21 du levier 16 présente une portion convexe 41, formée d'une suite de lignes juxtaposées et parallèles à l'axe 35 de l'articulation 22. On verra par la suite que l'orientation de la surface 21 permet au levier 16 de solliciter le tiroir 14 par des efforts orientés selon le sens de déplacement de celui-ci 14. Cela optimise le rendement du mécanisme de verrouillage 6, en réduisant autant que possible les efforts à fournir pour obtenir le verrouillage.The cam surface 21 of the lever 16 has a convex portion 41 formed of a series of lines juxtaposed and parallel to the axis 35 of the joint 22. It will be seen later that the orientation of the surface 21 allows the lever 16 to bias the slide 14 by efforts oriented in the direction of movement thereof 14. This optimizes the efficiency of the locking mechanism 6, reducing as much as possible the efforts to provide to obtain the lock.

Afin de coopérer avec le levier 16, une butée 42 est solidaire du carter 11, la butée 42 présentant la surface d'appui 23 destinée à coopérer avec la surface de came 21 du levier 16. Plus précisément ici la butée 42 est solidarisée à l'embase 13, laquelle est solidarisée au carter 11. En d'autres termes la butée 42 est solidaire du carter 11 par l'intermédiaire de l'embase 13. La butée 42 est indirectement solidarisée au carter 11. L'emploi d'une butée 42 permet de choisir le meilleur point d'appui pour le levier 16, comme on va le comprendre dans la suite de la description.In order to cooperate with the lever 16, a stop 42 is integral with the housing 11, the abutment 42 having the bearing surface 23 intended to cooperate with the cam surface 21 of the lever 16. More precisely here the stop 42 is secured to the base 13, which is secured to the housing 11. In other words the stop 42 is integral with the housing 11 through the base 13. The stop 42 is indirectly secured to the housing 11. The use of a stop 42 allows to choose the best point of support for the lever 16, as will be understood in the following description.

La butée 42 est disposée sur l'embase 13 de façon que l'articulation 22 du levier 16 se situe entre elle 42 et le tiroir 14. La surface d'appui 23 de la butée 42, destinée à coopérer avec la surface de came 21 du levier 16, est sur la trajectoire du tiroir 14. Cette surface 23 est donc dans le prolongement de la cavité longitudinale 24. Cela permet de solliciter le tiroir 14 dans son sens de déplacement dans le carter 11.The stop 42 is disposed on the base 13 so that the hinge 22 of the lever 16 is located between it 42 and the slide 14. The bearing surface 23 of the stop 42, intended to cooperate with the cam surface 21 of the lever 16, is in the path of the slide 14. This surface 23 is therefore in the extension of the longitudinal cavity 24. This allows to urge the slide 14 in its direction of movement in the housing 11.

De manière non limitative la surface d'appui 23 de la butée 42 présente une forme plane. La surface d'appui 23 forme avec l'embase 13 un angle α dont la valeur est comprise entre 60 et 90°, sachant que des valeurs d'angle de 75 à 85° ont donné de bons résultats. La surface d'appui 23 est inclinée, par rapport à l'embase 13, de façon que son sommet 43 soit plus proche du carter 11 que sa base 44. On verra par la suite que cette inclinaison donne la stabilité à la situation de verrouillage du mécanisme 6.In a nonlimiting manner the bearing surface 23 of the abutment 42 has a flat shape. The bearing surface 23 forms with the base 13 an angle α whose value is between 60 and 90 °, knowing that angle values of 75 to 85 ° gave good results. The bearing surface 23 is inclined, with respect to the base 13, so that its top 43 is closer to the housing 11 than its base 44. It will be seen later that this inclination gives stability to the locking situation mechanism 6.

Selon la première forme de réalisation décrite, la butée 42 forme avec l'embase 13 une pièce monobloc. Au final, le carter 11, l'embase 13 et la butée 42 forment une pièce monobloc. Cela fait gagner du temps à la fabrication. Il peut néanmoins alternativement être prévu que la butée 42 soit une pièce rapportée sur l'embase.According to the first embodiment described, the stop 42 forms with the base 13 a single piece. Finally, the housing 11, the base 13 and the stop 42 form a single piece. This saves time in manufacturing. It may alternatively be provided that the stop 42 is an insert on the base.

Le fonctionnement du dispositif 1 est détaillé ci-après à l'aide des figures 3 à 5, lesquelles correspondent chronologiquement à la mise en place de la chaussure 2 et au verrouillage de son élément d'ancrage 4.The operation of the device 1 is detailed below using the Figures 3 to 5 , which correspond chronologically to the introduction of the shoe 2 and the locking of its anchoring element 4.

Tout d'abord, sur la figure 3, la chaussure 2 est approchée du dispositif de retenue 1 de façon que l'élément d'ancrage 4 soit au-dessus de l'espace compris entre les mâchoires fixe 12 et mobile 15. L'espace présente son volume maximal parce que les mâchoires 12, 15 sont écartées au maximum l'une de l'autre, ce qui est possible parce que le levier 16 est dans une position de déverrouillage. Cette position est obtenue lorsque l'extrémité libre 34 est éloignée au maximum de l'embase 13.First, on the figure 3 , the shoe 2 is approached from the retaining device 1 so that the anchoring element 4 is above the space between the fixed jaws 12 and mobile 15. The space has its maximum volume because the jaws 12, 15 are spaced apart from each other, which is possible because the lever 16 is in an unlocked position. This position is obtained when the free end 34 is at the maximum distance from the base 13.

Après avoir approché la chaussure l'utilisateur peut l'appuyer sur le dispositif 1, comme montré sur la figure 4. Dans ce cas l'élément d'ancrage 4 se situe entre les mâchoires 12, 15. La manoeuvre de verrouillage consiste à faire pivoter le levier 16, selon l'articulation 22, pour approcher l'extrémité libre 34 vers l'embase 13. Lorsque le levier 16 tourne, la surface de came 21 prend appui sur la surface d'appui 23 de la butée 42 pour pousser le tiroir 14 dans un sens d'éloignement de la butée 42, ou aussi dans un sens de rapprochement de la paroi arrière 28 du carter 11. La rotation du levier 16 dans un sens de verrouillage provoque le rapprochement relatif des mâchoires mobile 15 et fixe 12.After approaching the shoe the user can press it on the device 1, as shown on the figure 4 . In this case the anchoring element 4 is located between the jaws 12, 15. The locking operation consists in pivoting the lever 16, according to the articulation 22, to approach the free end 34 towards the base 13. When the lever 16 rotates, the cam surface 21 is supported on the bearing surface 23 of the stop 42 to push the slide 14 in a direction away from the stop 42, or also in a direction of approximation of the wall rear 28 of the housing 11. The rotation of the lever 16 in a locking direction causes the relative approximation of the movable jaws 15 and fixed 12.

Lorsque le verrouillage est réalisé, selon la figure 5, l'extrémité libre 34 du levier 16 est dans sa position la plus rapprochée de l'embase 13. On observe que lorsque le levier 16 est dans la position de verrouillage, le point de contact 45, entre la surface de came 21 et la surface d'appui 23, est plus proche de l'embase 13 que ne l'est l'axe 35 de l'articulation 22 du levier 16. Dans cette configuration, le point de contact 45 est antérieur à l'axe d'articulation 22. En conséquence une sollicitation par la chaussure sur le tiroir 14 dans un sens de déverrouillage, donc vers la butée 42, augmente la pression de contact entre les surfaces de came 21 et d'appui 23. L'inclinaison selon l'angle α de la surface d'appui 23 crée un effort de poussée supplémentaire dans un sens de verrouillage. Le dispositif de retenue 1, et plus précisément le mécanisme de verrouillage 6, est donc structuré pour s'opposer au déverrouillage au cas où des sollicitations liées à la conduite tendraient à éloigner les mâchoires 12, 15 l'une de l'autre. Le mécanisme de verrouillage 6 s'oppose à l'ouverture des mâchoires, proportionnellement aux efforts qui leur sont appliqués. Le mécanisme de verrouillage 6 selon l'invention fonctionne ici selon le principe de la genouillère. En effet, la disposition du point de contact 45 par rapport à l'axe d'articulation 22 permet de générer un couple tendant à plaquer le levier 16 contre l'embase 13, c'est-à-dire à maintenir le levier dans la position de verrouillage, quand on déplace le tiroir 14, et donc l'axe 22, vers l'avant.When the lock is made, according to the figure 5 , the free end 34 of the lever 16 is in its position closest to the base 13. It is observed that when the lever 16 is in the locking position, the contact point 45, between the cam surface 21 and the support surface 23, is closer to the base 13 than is the axis 35 of the hinge 22 of the lever 16. In this configuration, the contact point 45 is anterior to the axis of articulation 22. As a result a bias by the shoe on the slide 14 in an unlocking direction, so towards the stop 42, increases the contact pressure between the cam surfaces 21 and support 23. The inclination according to the angle α of the bearing surface 23 creates an additional thrust force in a locking direction. The retaining device 1, and more precisely the locking mechanism 6, is structured to oppose the unlocking in case driving stresses tend to move the jaws 12, 15 away from each other. The locking mechanism 6 opposes the opening of the jaws, proportionally to the forces applied to them. The locking mechanism 6 according to the invention operates here according to the principle of the toggle joint. Indeed, the arrangement of the point of contact 45 with respect to the hinge pin 22 makes it possible to generate a torque tending to press the lever 16 against the base 13, that is to say to maintain the lever in the locking position, when moving the slide 14, and therefore the axis 22, forwards.

Selon la première forme de réalisation de l'invention, il est également prévu qu'un moyen élastique 51 sollicite le tiroir 14 dans un sens d'éloignement relatif des mâchoires fixe 12 et mobile 15. Bien entendu la sollicitation se fait vers la butée 42. Le moyen élastique 51 facilite l'écartement des mâchoires 12, 15, et par suite la libération de l'élément d'ancrage 4, lorsque l'utilisateur ramène le levier 16 en position de déverrouillage, comme sur la figure 3.According to the first embodiment of the invention, it is also provided that an elastic means 51 urges the slide 14 in a direction of relative distance from the fixed jaws 12 and mobile 15. Of course the bias is towards the stop 42 The elastic means 51 facilitates the spacing of the jaws 12, 15, and consequently the release of the anchoring element 4, when the user returns the lever 16 to the unlocking position, as on the figure 3 .

Le moyen élastique 51 permet de maintenir le contact entre la surface de came 21 et la surface d'appui 23 ce qui apporte une stabilité et un bon fonctionnement du mécanisme de verrouillage 6. Le moyen élastique 51 sollicite le tiroir 14 de manière à s'opposer au mouvement initial du tiroir engendré lors du passage de la position de verrouillage à la position de déverrouillage ou inversement.The elastic means 51 makes it possible to maintain the contact between the cam surface 21 and the bearing surface 23, which provides stability and good operation of the locking mechanism 6. The resilient means 51 urges the drawer 14 so as to to oppose the initial movement of the slide generated during the transition from the locking position to the unlocking position or vice versa.

On remarque au passage que si l'élément élastique n'était pas utilisé, il serait quand même possible de déverrouiller. Il faudrait alors que l'utilisateur soulève l'extrémité libre 34 du levier en position de déverrouillage, et qu'il pousse la chaussure en avant. Dans ce cas le tiroir 14, avec sa mâchoire 15, libère l'élément d'ancrage 4.We note in passing that if the elastic element was not used, it would still be possible to unlock. It would then be necessary for the user to raise the free end 34 of the lever in the unlocked position, and to push the shoe forward. In this case the slide 14, with its jaw 15, releases the anchoring element 4.

De manière non limitative le moyen élastique 51 est un ressort. Par exemple il s'agit d'un ressort hélicoïdal, logé dans le carter 11, entre le tiroir 14 et la paroi arrière 28, Le ressort est comprimé lorsque le mécanisme 6 est en situation de verrouillage avec les mâchoires 12, 15 rapprochées l'une de l'autre. Cet agencement est simple et facile à réaliser. Il peut bien sûr être prévu toute autre structure pour le moyen élastique, comme une cale en matériau élastomère, ou autre.In a nonlimiting manner, the elastic means 51 is a spring. For example it is a helical spring, housed in the housing 11, between the slide 14 and the rear wall 28, the spring is compressed when the mechanism 6 is in a locking position with the jaws 12, 15 close together. one of the other. This arrangement is simple and easy to achieve. It can of course be provided any other structure for the elastic means, such as a wedge of elastomeric material, or other.

On vient de voir que le déplacement du tiroir 14, dans un sens d'ouverture des mâchoires 12, 15, se fait par action du moyen élastique 51 ou par poussée de la chaussure. Cela signifie par corollaire que ce n'est pas le contact des surfaces de came 21 et d'appui 23 qui provoque l'ouverture. La surface d'appui 23 est une surface unique, dans le sens où c'est la seule surface prévue pour coopérer avec la surface de came 21, dans un sens de fermeture des mâchoires. En d'autres termes la surface d'appui 23 est prévue à l'exclusion de toute autre surface qui aurait pu être employée pour que le levier sollicite l'ouverture. Cela simplifie la structure du mécanisme de verrouillage 6, et donc du dispositif de retenue 1.We have just seen that the displacement of the slide 14, in an opening direction of the jaws 12, 15, is by action of the elastic means 51 or by pushing the shoe. This corollary means that it is not the contact of the cam surfaces 21 and support 23 which causes the opening. The bearing surface 23 is a single surface, in the sense that it is the only surface provided to cooperate with the cam surface 21, in a closing direction of the jaws. In other words, the bearing surface 23 is provided to the exclusion of any other surface that could have been used for the lever to request opening. This simplifies the structure of the locking mechanism 6, and therefore of the retaining device 1.

Toujours dans un esprit d'optimisation dans l'utilisation du dispositif de retenue 1, le tiroir 14 porte une butée 52 déformable élastiquement de manière réversible la butée étant conformée pour prendre contact avec une partie avant 53 de la chaussure 2. L'idée est de supprimer les jeux mécaniques entre l'avant 53 et le mécanisme de verrouillage 6, C'est pourquoi la butée 52 est dimensionnée pour être légèrement comprimée entre l'avant 53 et le mécanisme 6 lorsque la chaussure 2 est retenue.Still in the spirit of optimization in the use of the retaining device 1, the slide 14 carries a stop 52 resiliently deformable in a reversible manner the stop being shaped to make contact with a front portion 53 of the shoe 2. The idea is to remove the mechanical clearances between the front 53 and the locking mechanism 6, that is why the stop 52 is dimensioned to be slightly compressed between the front 53 and the mechanism 6 when the boot 2 is retained.

Afin de coopérer avec l'élément d'ancrage 4, la mâchoire mobile 15 présente une forme concave. Ainsi cette mâchoire peut loger l'élément d'ancrage 4, ce qui fait que ce dernier est retenu selon le principe d'une liaison par obstacle, par opposition à une liaison par frottement. Cela garantit une retenue fiable. De plus, la forme concave est ici semi-circulaire, pour mieux épouser l'élément d'ancrage 4, dont la section transversale est circulaire.In order to cooperate with the anchoring element 4, the movable jaw 15 has a concave shape. Thus this jaw can accommodate the anchoring element 4, so that the latter is retained on the principle of an obstacle connection, as opposed to a friction bond. This ensures a reliable hold. In addition, the concave shape is here semicircular, to better marry the anchoring element 4, whose cross section is circular.

La mâchoire fixe 12, quant à elle, présente une forme plane. Cela lui permet une coopération facile avec la mâchoire mobile 15, pour la retenue de l'élément d'ancrage 4. Et cela sert aussi de guide pour la mise en place de l'élément d'ancrage 4 entre les mâchoires 12, 15.The fixed jaw 12, in turn, has a flat shape. This allows him easy cooperation with the movable jaw 15, for the retention of the anchoring element 4. And this also serves as a guide for the establishment of the anchoring element 4 between the jaws 12, 15.

Les autres formes de réalisation de l'invention sont présentées ci-après à l'aide des figures 6 à 8. Pour des raisons de commodité, les éléments communs avec la première forme sont désignés par les mêmes références.The other embodiments of the invention are presented hereinafter with the aid of Figures 6 to 8 . For the sake of convenience, the elements common with the first form are designated by the same references.

Nous considérons tout d'abord la deuxième forme de réalisation, selon la figure 6.We first consider the second embodiment, according to the figure 6 .

On retrouve un dispositif de retenue 1. avec un mécanisme de verrouillage 6. Celui-ci comprend comme précédemment un carter 11, une embase 13, un tiroir 14, et un levier 16.There is a retainer 1. with a locking mechanism 6. This comprises as before a housing 11, a base 13, a slide 14, and a lever 16.

Ce qui est spécifique à la deuxième forme de réalisation, c'est la structure de la butée 62 disposée sur l'embase 13. Ici la butée 62 est constituée par une patte pliée, constituée par exemple de métal.What is specific to the second embodiment is the structure of the stop 62 disposed on the base 13. Here the stop 62 is constituted by a folded tab, consisting for example of metal.

Selon la deuxième forme de réalisation la butée 62 est une pièce rapportée sur l'embase, solidarisée à celle-ci 13 par tout moyen. Il peut s'agir d'un moyen permanent, comme un collage, un rivetage ou autre, ou d'un moyen démontable, comme une vis, une forme qui permet l'emboîtement, ou autre.According to the second embodiment the stop 62 is an insert on the base, secured thereto 13 by any means. It can be a permanent means, such as gluing, riveting or other, or a removable means, such as a screw, a shape that allows nesting, or other.

On remarque que la surface d'appui 23 de la butée 62, destinée à coopérer avec la surface de came 21 du levier 16, présente une portion concave 63. Celle-ci facilite le maintien du levier 16 dans une position stable de verrouillage.Note that the bearing surface 23 of the stop 62, intended to cooperate with the cam surface 21 of the lever 16, has a concave portion 63. This facilitates the maintenance of the lever 16 in a stable locking position.

La troisième forme de réalisation est présentée maintenant avec les figures 7 et 8.The third embodiment is presented now with the Figures 7 and 8 .

On retrouve un dispositif de retenue 1 avec un mécanisme de verrouillage 6. Celui-ci comprend un carter 11, une embase 13, un tiroir 74 et un levier 76.There is a retaining device 1 with a locking mechanism 6. This comprises a casing 11, a base 13, a slide 74 and a lever 76.

Ce qui est spécifique à la troisième forme de réalisation, c'est que le levier 16 est solidarisé au carter 11. Plus précisément le levier 16 est relié à un support 77, par une articulation 78. Le support 77 est lui-même solidarisé à l'embase 13, qui elle-même est solidarisée au carter 11, comme on l'a vu pour la première forme. Au final, selon la troisième forme, le levier 16 est relié indirectement au carter 11, par l'articulation 78. Nous sommes ici dans une organisation inverse à celles des première et deuxième formes, mais pour un fonctionnement similaire.What is specific to the third embodiment is that the lever 16 is secured to the housing 11. More precisely the lever 16 is connected to a support 77, by a hinge 78. The support 77 is itself secured to the base 13, which itself is secured to the housing 11, as seen for the first form. Finally, according to the third form, the lever 16 is connected indirectly to the housing 11, by the hinge 78. We are here in an inverse organization to those of the first and second forms, but for a similar operation.

On observe que, pour la troisième forme de réalisation, lorsque le levier 76 est dans la position de verrouillage, le point de contact 79, entre la surface de came 81 du levier 76 et la surface d'appui 83 du tiroir 74, est plus éloigné de l'embase 13 que ne l'est l'axe 84 de l'articulation 78 du levier 76. Dans cette configuration, le point de contact 79 est postérieur à l'axe d'articulation 84. Cela confère au mécanisme de verrouillage 6 une meilleure stabilité de la position de verrouillage. En effet, la disposition du point de contact 79 par rapport à l'axe d'articulation 84 permet de générer un couple tendant à plaquer le levier 76 contre l'embase 13, c'est-à-dire à maintenir le levier dans la position de verrouillage, quand on déplace le tiroir 74, et donc le point de contact 79, vers l'avant.It is observed that, for the third embodiment, when the lever 76 is in the locking position, the point of contact 79 between the cam surface 81 of the lever 76 and the bearing surface 83 of the slide 74 is more away from the base 13 that is the axis 84 of the articulation 78 of the lever 76. In this configuration, the point of contact 79 is posterior to the hinge axis 84. This gives the locking mechanism 6 better stability of the locking position. Indeed, the arrangement of the contact point 79 relative to the hinge axis 84 generates a torque tending to press the lever 76 against the base 13, that is to say to maintain the lever in the locking position, when the slide 74, and therefore the contact point 79, is moved forward.

Dans tous les cas l'invention est réalisée à partir de matériaux et selon des techniques de mise en oeuvre connus de l'homme du métier.In all cases the invention is made from materials and according to processing techniques known to those skilled in the art.

Bien entendu l'invention n'est pas limitée aux formes de réalisation ci-avant décrites, et comprend tous les équivalents techniques pouvant entrer dans la portée des revendications qui vont suivre.Naturally, the invention is not limited to the embodiments described above, and includes all technical equivalents that fall within the scope of the claims that follow.

En particulier de nombreuses variantes de structures peuvent être prévues pour le tiroir ou le levier.In particular, many variants of structures can be provided for the drawer or the lever.

L'invention couvre également un mécanisme de verrouillage 6 inversée, c'est-à-dire un mécanisme privilégiant une position de verrouillage. Dans ce quatrième mode de réalisation non représenté, le moyen élastique 51 sollicite le tiroir dans un sens de rapprochement relatif des mâchoires fixe 12 et mobile 15. La premiers position stable est la position de verrouillage. Lorsqu'on agit sur le levier, celui-ci provoque le déplacement du tiroir de manière à écarter les mâchoires, l'une de l'autre. Ce déplacement est obtenu par une solution analogue aux solutions précédentes, grâce à la coopération d'une surface de came avec une surface d'appui. Dans cette configuration de déverrouillage, le tiroir est davantage sollicité par le moyen élastique 51 que dans les modes de réalisation précédent. Cette variante permet de moins solliciter le mécanisme. En effet, le dispositif de retenue est le plus souvent en position de verrouillage. Or, comme dans cette configuration, le moyen élastique est moins contraint, il sollicite moins les autres éléments du dispositif.The invention also covers an inverted locking mechanism 6, that is to say a mechanism favoring a locking position. In this fourth embodiment not shown, the resilient means 51 urges the drawer in a direction of relative approximation of the fixed jaws 12 and movable 15. The first stable position is the locking position. When acting on the lever, it causes the movement of the drawer to move the jaws away from each other. This displacement is obtained by a solution similar to the previous solutions, thanks to the cooperation of a cam surface with a bearing surface. In this unlocking configuration, the drawer is more stressed by the elastic means 51 than in the previous embodiments. This variant makes it less possible to solicit the mechanism. Indeed, the retainer is most often in the locking position. However, as in this configuration, the elastic means is less constrained, it requires less other elements of the device.

Le moyen, élastique 51 peut donc solliciter le tiroir dans un sens d'éloignement relatif des mâchoires fixe 12 et mobile 15, comme c'est le cas dans les trois premiers modes de réalisation. Cependant, il peut également solliciter le tiroir dans un sens de rapprochement relatif des mâchoires fixe 12 et mobile 15, comme c'est le cas dans le quatrième mode de réalisation. Le moyen élastique 51 est ainsi apte à solliciter le tiroir de manière à provoquer le déplacement relatif de la mâchoire mobile 15 par rapport à la mâchoire fixe 12. Bien entendu, le moyen élastique agit sur le tiroir quand il est sollicité, par exemple, quand on comprime un ressort de compression.The elastic means 51 can therefore urge the drawer in a direction of relative distance from the fixed jaws 12 and movable 15, as is the case in the first three embodiments. However, it can also urge the drawer in a direction of relative approximation of the fixed jaws 12 and movable 15, as is the case in the fourth embodiment. The elastic means 51 is thus able to urge the drawer so as to cause the relative movement of the movable jaw 15 relative to the fixed jaw 12. Of course, the elastic means acts on the drawer when it is stressed, for example when a compression spring is compressed.
