Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

L'invention concerne le domaine des dispositifs de retenue d'une chaussure sur une planche de glisse. Elle concerne plus particulièrement les dispositifs de retenue qui permettent un réglage longitudinal de la position de la chaussure sur la planche de glisse. Elle trouve pour application particulièrement avantageuse le ski de fond.The invention relates to the field of devices for retaining a boot on a gliding board. It relates more particularly to retaining devices which allow longitudinal adjustment of the position of the boot on the gliding board. It finds a particularly advantageous application in cross-country skiing.

ÉTAT DE LA TECHNIQUESTATE OF THE ART

Dans certains sports de glisse il est avantageux de pouvoir régler la position longitudinale d'un dispositif de retenue d'une chaussure sur une planche de glisse. Dans le cas du ski de fond par exemple, l'utilisateur souhaitera en effet modifier la position longitudinale de sa chaussure sur le ski notamment pour s'adapter aux conditions d'enneigement, améliorer ses performances ou améliorer son confort. De manière simplifiée, si l'utilisateur déplace le dispositif de retenue et donc sa chaussure vers l'avant, cela conduira à améliorer la friction et l'accroche de la planche de glisse dans la neige. Si au contraire l'utilisateur déplace le dispositif de retenue vers l'arrière de la planche de glisse, la friction sera réduite favorisant la glisse et donc la vitesse de l'utilisateur.In certain sliding sports, it is advantageous to be able to adjust the longitudinal position of a device for retaining a boot on a sliding board. In the case of cross-country skiing for example, the user will indeed wish to modify the longitudinal position of his boot on the ski, in particular to adapt to snow conditions, improve his performance or improve his comfort. In a simplified manner, if the user moves the retaining device and therefore his boot forward, this will improve the friction and the grip of the board for gliding in the snow. If, on the contrary, the user moves the retainer towards the rear of the gliding board, the friction will be reduced, favoring gliding and therefore the speed of the user.

Il existe de nombreuses solutions pour permettre un réglage de la position longitudinale du dispositif de retenue sur la planche de glisse, comme par exemple, les constructions décrites dans les documents WO2005/113081 , WO2012/045723 ou WO2017/095232 .There are many solutions to allow adjustment of the longitudinal position of the retaining device on the gliding board, such as, for example, the constructions described in the documents. WO2005 / 113081 , WO2012 / 045723 or WO2017 / 095232 .

Ces solutions présentent quelques inconvénients. En particulier, elles s'avèrent relativement encombrantes, voire lourdes. Par ailleurs, elles sont assez complexes, notamment du fait qu'elles comprennent un grand nombre de pièces constitutives. De plus, l'ergonomie d'usage ne s'avère pas très simple car elle nécessite l'actionnement de différents éléments en fonction du réglage souhaité : solidarisation de la chaussure vs réglage longitudinal du dispositif. Pour certaines solutions, du fait de leur exposition à l'environnement extérieur et en particulier au gel ou à l'accumulation de neige, leur fiabilité peut être compromise lors de la pratique en extérieur.These solutions have some drawbacks. In particular, they turn out to be relatively bulky, even heavy. Moreover, they are quite complex, in particular due to the fact that they include a large number of constituent parts. In addition, the ergonomics of use does not prove to be very simple because it requires the actuation of various elements according to the desired adjustment: securing of the boot vs. longitudinal adjustment of the device. For certain solutions, due to their exposure to the external environment and in particular to frost or to the accumulation of snow, their reliability may be compromised when practicing outdoors.

Le but de l'invention est de proposer un dispositif de retenue d'une chaussure sur une planche de glisse améliorée.The aim of the invention is to provide a device for retaining a boot on an improved gliding board.

Un but est notamment de proposer un dispositif de retenue compact et notamment léger.One aim is in particular to provide a compact and in particular light retaining device.

DESCRIPTION DÉTAILLÉE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Dans la suite de la description, il sera fait usage de termes tels que « horizontal », « vertical », « transversal », « supérieur », « inférieur », « latéral », « haut », « bas », « droite », « gauche », « avant », « arrière », « devant », « derrière ». Ces termes doivent être interprétés de façon relative en relation avec la position normale que l'engin de glisse occupe quand l'utilisateur l'utilise sur une piste sensiblement plane.In the remainder of the description, use will be made of terms such as "horizontal", "vertical", "transverse", "upper", "lower", "lateral", "top", "bottom", "right". , "Left", "front", "rear", "front", "behind". These terms must be interpreted relatively in relation to the normal position that the gliding apparatus occupies when the user uses it on a substantially flat track.

On utilisera également un repère dont la direction arrière/avant correspond à l'axe X, la direction transversale ou droite/gauche correspond à l'axe Y et la direction verticale ou bas/haut correspond à l'axe Z.We will also use a frame whose rear / front direction corresponds to the X axis, the transverse or right / left direction corresponds to the Y axis and the vertical or down / up direction corresponds to the Z axis.

De manière classique, dans le cadre de la présente invention, le terme « crémaillère » désigne un dispositif mécanique présentant des reliefs aptes à coopérer avec un organe de verrouillage. Ces reliefs ou crans sont répartis de manière sensiblement linéaire et forment une série d'encoches aptes à recevoir une partie de l'organe de verrouillage.Conventionally, in the context of the present invention, the term “rack” designates a mechanical device having reliefs able to cooperate with a locking member. These reliefs or notches are distributed so substantially linear and form a series of notches suitable for receiving part of the locking member.

En référence aux figures 1 à 11, un exemple non limitatif de la présente invention va maintenant être décrit en détail.With reference to figures 1 to 11 , a non-limiting example of the present invention will now be described in detail.

La figure 1 notamment illustre un engin de glisse 4 comprenant une planche de glisse 3 équipée d'un élément de guidage 2 sur lequel se monte un dispositif de retenue 1, habituellement désignée par le terme « fixation », pour une chaussure 5.The figure 1 in particular illustrates a gliding device 4 comprising a gliding board 3 equipped with a guide element 2 on which is mounted a retaining device 1, usually designated by the term “binding”, for a shoe 5.

La planche de glisse 3 présente une face supérieure 31 tournée au regard du dispositif de retenue 1 et une face inférieure 32 destinée à venir au contact du substrat, typiquement de la neige. La face inférieure 32 définit ainsi une surface et un plan de glisse. Le plan de glisse correspond au plan XY du repère orthogonal XYZ illustré en figure 1.The gliding board 3 has an upper face 31 facing the retaining device 1 and a lower face 32 intended to come into contact with the substrate, typically snow. The lower face 32 thus defines a surface and a sliding plane. The sliding plane corresponds to the XY plane of the XYZ orthogonal coordinate system illustrated in figure 1 .

De manière parfaitement connue, le dispositif de retenue 1 comprend un châssis 11 portant un mécanisme de maintien 10M pour la chaussure 5. Le mécanisme de maintien 10M permet sélectivement de mettre en prise la chaussure avec le dispositif de retenue 1 ou de libérer la chaussure du dispositif de retenue 1. Dans le cas de la pratique du ski de fond ou du ski de randonnée, le mécanisme de maintien 10M permet à la chaussure de conserver un ou plusieurs degrés de liberté. Généralement, la chaussure est articulée en rotation sur le dispositif de retenue 1 autour d'un axe horizontal transverse Y à la direction de glisse, au niveau des orteils.In a perfectly known manner, the retaining device 1 comprises a frame 11 carrying a retaining mechanism 10M for the boot 5. The retaining mechanism 10M selectively makes it possible to engage the boot with the retaining device 1 or to release the boot from the boot. retention device 1. In the case of cross-country skiing or ski touring, the retention mechanism 10M allows the boot to retain one or more degrees of freedom. Generally, the boot is articulated in rotation on the retaining device 1 about a horizontal axis Y transverse to the sliding direction, at the toes.

L'exemple illustré en figure 1 s'applique, par exemple, au ski de fond. La chaussure 5 comprend un élément d'accrochage 51, typiquement un arbre s'étendant selon une direction sensiblement transversale Y à la direction longitudinale principale X de la planche de glisse, lorsque la chaussure est en prise avec le mécanisme de maintien. L'élément d'accrochage est intégré dans un évidement de l'avant de la semelle de la chaussure. La demande EP-A-0 913 102 illustre une chaussure incorporant un élément d'accrochage tel que décrit précédemment.The example shown in figure 1 applies, for example, to cross-country skiing. The boot 5 comprises a fastening element 51, typically a shaft extending in a direction substantially transverse Y to the main longitudinal direction X of the gliding board, when the boot is engaged with the holding mechanism. The hooking element is integrated in a recess in the front of the sole of the shoe. Requirement EP-A-0 913 102 illustrates a shoe incorporating a fastening element as described above.

Le mécanisme de maintien 10M est donc configuré pour coopérer avec un élément d'accrochage 51 appartenant à la chaussure 5 de sorte que la chaussure soit maintenue en position par rapport au châssis 11.The holding mechanism 10M is therefore configured to cooperate with a fastening element 51 belonging to the boot 5 so that the boot is held in position relative to the frame 11.

Pour assurer la solidarisation de la chaussure 5 avec le dispositif de retenue 1, le mécanisme de maintien 10M comprend une mâchoire fixe 111, une mâchoire mobile 12, un actionneur 13 et un organe de liaison 14.To ensure the attachment of the shoe 5 with the retaining device 1, the retaining mechanism 10M comprises a fixed jaw 111, a movable jaw 12, an actuator 13 and a connecting member 14.

La mâchoire mobile 12 comprend un corps 121 portant un crochet 122 qui permet de venir fermer un emplacement 112 défini par la mâchoire fixe 111 et à l'intérieur duquel s'insère l'élément d'accrochage 51 de la chaussure 5.The movable jaw 12 comprises a body 121 carrying a hook 122 which makes it possible to close a location 112 defined by the fixed jaw 111 and inside which the hooking element 51 of the boot 5 is inserted.

Selon un mode de réalisation, le crochet 122 est une pièce métallique rapportée sur le corps 121 de la mâchoire mobile. Cela permet de renforcer la robustesse du mécanisme de maintien 10M.According to one embodiment, the hook 122 is a metal part attached to the body 121 of the movable jaw. This makes it possible to reinforce the robustness of the 10M holding mechanism.

Selon un mode de réalisation, la mâchoire fixe 111 est réalisée par une partie du châssis 11. Alternativement, la mâchoire fixe peut être une pièce rapportée sur le châssis. Avantageusement, c'est une pièce métallique, plus robuste, assurant une meilleure tenue et résistance à l'usure de frottement avec l'élément d'accrochage 51 de la chaussure.According to one embodiment, the fixed jaw 111 is produced by a part of the frame 11. Alternatively, the fixed jaw can be a part attached to the frame. Advantageously, it is a metal part, more robust, ensuring better hold and resistance to frictional wear with the fastening element 51 of the shoe.

La mâchoire 12 est mobile entre :

  • une position d'enclenchement, illustrée en figures 4 et 7, pour laquelle elle est apte à coopérer avec la mâchoire fixe 111 de sorte à permettre la solidarisation de l'élément d'accrochage 51 avec le dispositif de retenue 1 tout en permettant la rotation de la chaussure autour d'un axe transversal Y1 au dispositif de retenue 1, et
  • une position de libération, illustrée en figures 5 et 8, pour laquelle elle est dans une configuration permettant la désolidarisation ou désengagement de l'élément d'accrochage 51 avec le dispositif de retenue 1.
The jaw 12 is movable between:
  • a latching position, illustrated in figures 4 and 7 , for which it is able to cooperate with the fixed jaw 111 so as to allow the attachment of the fastening element 51 with the retaining device 1 while allowing the rotation of the boot about a transverse axis Y1 to the device holdback 1, and
  • a release position, shown in figures 5 and 8 , for which it is in a configuration allowing the disengagement or disengagement of the fastening element 51 with the retaining device 1.

L'actionneur 13 commande un déplacement de la mâchoire mobile 12 pour la faire sélectivement passer de la position d'enclenchement vers la position de libération et inversement. Dans cet exemple, l'actionneur 13 est un levier monté pivotant sur le corps 121 de la mâchoire mobile 12, autour d'un axe transversal Y13, grâce à deux arbres 132. Chacun de ces arbres 132 traverse un côté de l'actionneur et s'insère dans un trou latéral 125 du corps 121 de la mâchoire mobile 12. Les deux trous latéraux 125, disposés de chaque côté du corps 121, sont alignés selon un axe transversal Y13' qui se confond avec l'axe transversal Y13 lorsque l'actionneur est assemblé au corps 121 de la mâchoire mobile.The actuator 13 controls a movement of the movable jaw 12 to selectively move it from the engagement position to the release position and vice versa. In this example, the actuator 13 is a lever mounted to pivot on the body 121 of the movable jaw 12, around a transverse axis Y13, thanks to two shafts 132. Each of these shafts 132 passes through one side of the actuator and fits into a lateral hole 125 of the body 121 of the movable jaw 12. The two lateral holes 125, arranged on each side of the body 121, are aligned along a transverse axis Y13 'which merges with the transverse axis Y13 when the The actuator is assembled to the body 121 of the movable jaw.

La transmission du mouvement entre l'actionneur 13 et la mâchoire mobile 12 est assurée grâce à l'organe de liaison 14. Dans cet exemple, l'organe de liaison 14 est un fil métallique, par exemple en acier, en forme de « U ». Ici, le fil a une section circulaire. Il comprend deux branches latérales 142 et une branche transversale 141 reliant les branches latérales 142. La branche transversale 141 s'étend selon un axe transversal Y14. Chaque branche latérale 142 est coudée. Au niveau d'une première extrémité, chaque branche latérale 142 comprend une extension transversale 143 destinée à se loger dans un trou 131 ménagé sur un bord latéral de l'actionneur 13. La deuxième extrémité est reliée à une extrémité de la branche transversale 141. La branche transversale 141 est prévue pour venir s'insérer dans un logement 113 du châssis 11. Lorsque la branche transversale 141 est dans ce logement 113, l'organe de liaison 14 peut pivoter autour de l'axe transversal Y14.The transmission of the movement between the actuator 13 and the movable jaw 12 is ensured by means of the connecting member 14. In this example, the connecting member 14 is a metal wire, for example made of steel, in the shape of a "U". ". Here, the wire has a circular section. It comprises two lateral branches 142 and a transverse branch 141 connecting the lateral branches 142. The transverse branch 141 extends along a transverse axis Y14. Each side branch 142 is bent. At a first end, each lateral branch 142 comprises a transverse extension 143 intended to be received in a hole 131 made on a lateral edge of the actuator 13. The second end is connected to one end of the transverse branch 141. The transverse branch 141 is designed to fit into a housing 113 of the frame 11. When the transverse branch 141 is in this housing 113, the connecting member 14 can pivot about the transverse axis Y14.

Ainsi, lorsqu'on fait pivoter l'actionneur 13 autour de son axe Y13, on fait pivoter l'organe de liaison 14 autour de son axe Y14. Comme la branche transversale 141 est en prise avec le châssis 11, cette combinaison de rotation entraîne la translation longitudinale de la mâchoire mobile 12 par rapport au châssis 11.Thus, when the actuator 13 is rotated around its axis Y13, the connecting member 14 is rotated around its axis Y14. As the transverse branch 141 is engaged with the frame 11, this combination of rotation drives the longitudinal translation of the movable jaw 12 relative to the frame 11.

Dans cet exemple, une partie du corps 121 de la mâchoire mobile 12 se situe entre les branches latérales 142, au niveau de la branche transversale 141. Aussi, pour ne pas bloquer la translation du corps 121 selon la cinématique décrite précédemment, une lumière horizontale 1241, formant un trou oblong s'étendant longitudinalement, est ménagée, de part et d'autre du corps 121, afin de recevoir une portion de la branche transversale 141.In this example, a part of the body 121 of the movable jaw 12 is located between the lateral branches 142, at the level of the transverse branch 141. Also, in order not to block the translation of the body 121 according to the kinematics described above, a horizontal slot 1241, forming an oblong hole extending longitudinally, is provided, on either side of the body 121, in order to receive a portion of the transverse branch 141.

Ainsi, pour un bon fonctionnement du mécanisme de maintien, il est nécessaire d'avoir un dégagement selon une direction X, sensiblement horizontale, afin de ne pas obstruer la translation du corps 121. Par ailleurs, lorsqu'on actionne le mécanisme de maintien, pour solidariser ou désolidariser la chaussure, la branche transversale 141 doit être maintenue au fond du logement 113. Aussi, il est préférable de limiter le déplacement vertical, vers le haut, de la branche transversale 141, afin qu'elle reste au fond du logement 113. Dans cet exemple, cette butée verticale est assurée par la face supérieure de la lumière horizontale 1241.Thus, for proper operation of the holding mechanism, it is necessary to have a clearance in a direction X, substantially horizontal, so as not to obstruct the translation of the body 121. Furthermore, when the holding mechanism is actuated, to secure or separate the shoe, the transverse branch 141 must be maintained at the bottom of the housing 113. Also, it is preferable to limit the vertical displacement, upwards, of the transverse branch 141, so that it remains at the bottom of the housing 113. In this example, this vertical stop is provided by the upper face of the horizontal slot 1241.

Lorsqu'on abaisse l'actionneur 13, le corps 121 vient, dans un premier temps, en butée longitudinale contre le châssis. Dans cette configuration, la mâchoire mobile 12 coopère avec la mâchoire fixe 111 pour maintenir l'élément d'accrochage 51 de la chaussure. Si on poursuit la rotation de l'actionneur pour l'abaisser davantage, on fait basculer le mécanisme de maintien dans une configuration stable correspondant à une position d'enclenchement de la mâchoire mobile. Cette position stable est obtenue grâce au positionnement de l'accroche de l'organe de liaison sur l'actionneur 13 par rapport à son axe de pivotement Y13 et au fait que les branches latérales 142 soient coudées. Dans cette configuration, l'organe de liaison 14 exerce un effort sur l'actionneur pour le plaquer contre une butée verticale.When the actuator 13 is lowered, the body 121 first comes into longitudinal abutment against the frame. In this configuration, the movable jaw 12 cooperates with the fixed jaw 111 to hold the fastening element 51 of the boot. If the actuator continues to rotate in order to lower it further, the retaining mechanism is tilted into a stable configuration corresponding to an engagement position of the movable jaw. This stable position is obtained thanks to the positioning of the hook of the connecting member on the actuator 13 relative to its pivot axis Y13 and to the fact that the side branches 142 are bent. In this configuration, the connecting member 14 exerts a force on the actuator to press it against a vertical stop.

Les documents FR-A-2638974 et FR-A-2899121 décrivent des mécanismes de maintien dont le fonctionnement est similaire au fonctionnement du mécanisme de maintien 10M.The documents FR-A-2638974 and FR-A-2899121 describe holding mechanisms whose operation is similar to the operation of the holding mechanism 10M.

Sur l'exemple illustré, on notera que le dispositif de retenue 1 comporte également une pièce élastique 15 contre laquelle l'avant de la chaussure de glisse est destiné à entrer au contact. Cette pièce élastique 15 est habituellement qualifiée de « flexor ».In the example illustrated, it will be noted that the retaining device 1 also comprises an elastic part 15 against which the front of the sliding boot is intended to come into contact. This elastic part 15 is usually referred to as a “flexor”.

Selon l'invention, le dispositif de retenue 1 coulisse longitudinalement par rapport à la planche de glisse 3. Pour cela, le châssis 11 du dispositif de retenue 1 présente un axe longitudinal médian, parallèle à la direction X, et comporte deux profils, situés de part et d'autre de cet axe longitudinal médian. Chacun de ces profils forment une rainure longitudinale débouchante 1141, transversalement, en direction de l'axe longitudinal médian. Ces deux rainures, se faisant face, sont destinées à recevoir respectivement un rail de guidage 22 porté par un élément de guidage 2 solidaire de la planche de glisse 3. Ces rainures forment chacune un coulisseau 114. Chacun de ces coulisseaux 114 est ainsi guidé en translation par le rail 22. De manière avantageuse, la complémentarité du châssis 11 et de l'élément de guidage 2, plus particulièrement la complémentarité des coulisseaux 114 et des rails 22, en plus d'assurer une fonction de guidage en translation, empêche un éloignement du châssis 11 par rapport à la planche de glisse 3 selon la direction Z. Ainsi, la liaison cinématique formée par chaque coulisseau 114 et son rail 22 complémentaire est une liaison glissière, c'est-à-dire une liaison avec un seul degré de liberté correspondant au coulissement du châssis 11 selon la direction X.According to the invention, the retaining device 1 slides longitudinally with respect to the gliding board 3. For this, the frame 11 of the retaining device 1 has a median longitudinal axis, parallel to the direction X, and comprises two profiles, located on either side of this median longitudinal axis. Each of these profiles form a longitudinal groove opening 1141, transversely, in the direction of the median longitudinal axis. These two grooves, facing each other, are intended to receive respectively a guide rail 22 carried by a guide element 2 integral with the gliding board 3. These grooves each form a slide 114. Each of these slides 114 is thus guided in translation by the rail 22. Advantageously, the complementarity of the frame 11 and of the guide element 2, more particularly the complementarity of the slides 114 and the rails 22, in addition to providing a translational guide function, prevents a distance of the frame 11 from the gliding board 3 in the Z direction. Thus, the kinematic link formed by each slide 114 and its complementary rail 22 is a slide link, that is to say a link with a single degree of freedom corresponding to the sliding of the frame 11 in the direction X.

Sur l'exemple de réalisation illustré, les rails 22 sont portés par une pièce distincte, l'élément de guidage 2, solidaire de la planche de glisse 3. L'élément de guidage 2 forme ici une plaque d'interface rapportée sur la planche de glisse. De préférence, une face inférieure 23 de la plaque d'interface 2 est placée directement au contact de la face supérieure 31 de la planche de glisse 3. L'élément de guidage 2 est par exemple collée, soudée ou vissée sur la planche de glisse 3.In the illustrated embodiment, the rails 22 are carried by a separate part, the guide element 2, integral with the gliding board 3. The guide element 2 here forms an interface plate attached to the board. of sliding. Preferably, a lower face 23 of the interface plate 2 is placed directly in contact with the upper face 31 of the gliding board 3. The guide element 2 is for example glued, welded or screwed onto the gliding board. 3.

Selon un exemple de réalisation alternatif non illustré, la planche de glisse 3 forme les rails 22 de guidage. Ainsi, l'élément de guidage 2 portant les rails 22 est formé directement par la planche de glisse 3.According to an alternative embodiment which is not illustrated, the sliding board 3 forms the guide rails 22. Thus, the guide element 2 carrying the rails 22 is formed directly by the gliding board 3.

Ainsi, le châssis 11 est configuré pour coopérer avec l'élément de guidage 2 solidaire de la planche de glisse de manière à pouvoir coulisser longitudinalement par rapport à la planche de glisse.Thus, the frame 11 is configured to cooperate with the guide element 2 integral with the gliding board so as to be able to slide longitudinally relative to the gliding board.

Dans cet exemple, la mâchoire mobile 12 est également montée coulissante, selon une direction longitudinale X, sur l'élément de guidage 2. Ainsi, de manière analogue, le corps 121 de la mâchoire mobile 12 comprend des coulisseaux 123 portant chacun une rainure longitudinale débouchante 1231. Ces coulisseaux 123 sont destinés à coopérer avec les rails 22 de l'élément de guidage 2 afin de guider la mâchoire mobile 12 selon un seul degré de liberté correspondant au coulissement du corps 121 selon la direction X. Cette construction permet de concevoir des coulisseaux 114, 123 relativement courts ce qui est préférable pour assurer un bon guidage et limiter le risque de coincement résultant d'une grande longueur de guidage des coulisseaux.In this example, the movable jaw 12 is also slidably mounted, in a longitudinal direction X, on the guide element 2. Thus, in a similar manner, the body 121 of the movable jaw 12 comprises slides 123 each carrying a longitudinal groove. opening 1231. These slides 123 are intended to cooperate with the rails 22 of the guide element 2 in order to guide the movable jaw 12 according to a single degree of freedom corresponding to the sliding of the body 121 in the direction X. This construction makes it possible to design relatively short slides 114, 123 which is preferable to ensure good guidance and limit the risk of jamming resulting from a large guide length of the slides.

Selon un mode de réalisation alternatif, la mâchoire mobile 12 est montée coulissante, selon une direction longitudinale X, sur le châssis 11. Il existe donc des moyens de guidage, non illustrés, entre ces deux pièces. Ces moyens de guidage peuvent être similaires aux moyens de guidage décrits précédemment, à savoir la coopération entre des coulisseaux et des rails ménagés respectivement sur le corps 121 de la mâchoire mobile 12 et sur le châssis 11.According to an alternative embodiment, the movable jaw 12 is slidably mounted, in a longitudinal direction X, on the frame 11. There are therefore guide means, not shown, between these two parts. These guide means can be similar to the guide means described above, namely the cooperation between slides and rails formed respectively on the body 121 of the movable jaw 12 and on the frame 11.

Un mécanisme de réglage 10R, porté en partie par le châssis 11, permet de modifier et verrouiller la position longitudinale du châssis par rapport à la planche de glisse 3. Comme nous l'avons vu précédemment, le châssis 11 peut se translater longitudinalement par rapport à la planche de glisse 3, grâce à des moyens de guidage 22, 114. Pour finaliser le réglage du positionnement longitudinal du dispositif de retenue 1, il faut pouvoir bloquer cette translation du châssis. A cet effet, le mécanisme de réglage 10R comporte une crémaillère 21 solidaire de la planche de glisse 3 et un organe de verrouillage 141 configuré pour coopérer avec la crémaillère 21.An adjustment mechanism 10R, carried in part by the frame 11, makes it possible to modify and lock the longitudinal position of the frame with respect to the gliding board 3. As we have seen previously, the frame 11 can translate longitudinally with respect to to the gliding board 3, by means of guide means 22, 114. To finalize the adjustment of the longitudinal positioning of the retaining device 1, it is necessary to be able to block this translation of the frame. For this purpose, the adjustment mechanism 10R comprises a rack 21 integral with the gliding board 3 and a locking member 141 configured to cooperate with the rack 21.

Comme évoqué précédemment, la crémaillère 21 correspond à une succession de reliefs ou crans 211. Chaque relief 211 s'étend selon une direction transversale Y. Ils sont alignés selon une direction longitudinale et sont espacés de manière régulière de sorte à créer des encoches 212, délimitées par deux reliefs successifs. La crémaillère 21 comprend suffisamment de reliefs 211 pour définir au moins deux encoches 212. Chaque encoche 212 de la crémaillère 21 est destinée à recevoir l'organe de verrouillage 141. Ainsi, la largeur d'une encoche 212 est sensiblement égale, voire légèrement supérieure, à la largeur de l'organe de verrouillage 141.As mentioned above, the rack 21 corresponds to a succession of reliefs or notches 211. Each relief 211 extends in a transverse direction Y. They are aligned in a longitudinal direction and are spaced regularly so as to create notches 212, delimited by two successive reliefs. The rack 21 comprises enough reliefs 211 to define at least two notches 212. Each notch 212 of the rack 21 is intended to receive the locking member 141. Thus, the width of a notch 212 is substantially equal, or even slightly greater. , to the width of the locking member 141.

Dans cet exemple, la crémaillère 21 est portée par l'élément de guidage 2. Selon une variante, la crémaillère 21 est indépendante de l'élément de guidage 2. Elle peut être ménagée sur une pièce distincte, par exemple, une plaque d'interface ou une crémaillère seule. Elle peut aussi être ménagée directement sur la planche de glisse. Dans ce cas, la surface supérieure 32 de la planche de glisse 3 est conformée pour former la crémaillère 21. La crémaillère peut être, par exemple, un insert métallique.In this example, the rack 21 is carried by the guide element 2. According to a variant, the rack 21 is independent of the guide element 2. It can be provided on a separate part, for example, a plate of interface or a single rack. It can also be placed directly on the gliding board. In this case, the upper surface 32 of the gliding board 3 is shaped to form the rack 21. The rack can be, for example, a metal insert.

Selon l'invention, l'organe de verrouillage 141 est porté par l'organe de liaison 14 reliant l'actionneur 13 à un point d'accroché 113 fixe par rapport au châssis 11.According to the invention, the locking member 141 is carried by the connecting member 14 connecting the actuator 13 to an attachment point 113 fixed relative to the frame 11.

Au sens de l'invention, un point d'accroché 113 fixe par rapport au châssis 11 correspond à un logement d'une partie de l'organe de liaison de sorte que cette partie en prise ne puisse pas se déplacer relativement par rapport au châssis, au moins selon une direction horizontale X, au moins dans une configuration d'usage.Within the meaning of the invention, an attachment point 113 fixed relative to the frame 11 corresponds to a housing of a part of the connecting member so that this engaged part cannot move relative to the frame. , at least in a horizontal direction X, at least in a configuration of use.

Dans l'exemple décrit, l'organe de verrouillage correspond à la branche transversale 141 de l'organe de liaison 14. Selon ce mode de réalisation, l'organe de verrouillage est une barre, s'étendant selon une direction transversale Y. Dans une configuration de verrouillage, l'organe de verrouillage 141 est destiné à coopérer, d'une part, avec le logement 113 du châssis 11 et, d'autre part, avec une encoche 212 de la crémaillère 21. Autrement dit, une portion de la branche transversale 141 est conçue pour s'insérer dans une encoche 212 alors qu'une autre portion de la branche transversale 141 est conçue pour s'introduire dans le logement 113. Le dimensionnement des encoches 212, et plus particulièrement la hauteur des reliefs délimitant les encoches, est suffisante pour immobiliser la branche transversale 141 selon une direction longitudinale X, lorsque la branche transversale est logée dans l'encoche. D'autre part, du fait que, dans cette configuration de verrouillage, la branche transversale coopère aussi avec le logement 113 du châssis, le châssis 11 est également immobilisé selon une direction longitudinale X. La branche transversale 141 sert alors de liaison rigide, selon la direction longitudinale X, entre la crémaillère 21 et le châssis 11 et donc entre la planche de glisse 3 et le dispositif de retenue 1. L'immobilisation du châssis 11 selon les autres directions Y, Z est réalisée par la liaison glissière résultant de la coopération entre les coulisseaux 114 et les rails 22.In the example described, the locking member corresponds to the transverse branch 141 of the connecting member 14. According to this embodiment, the locking member is a bar, extending in a transverse direction Y. a locking configuration, the locking member 141 is intended to cooperate, on the one hand, with the housing 113 of the frame 11 and, on the other hand, with a notch 212 of the rack 21. In other words, a portion of the transverse branch 141 is designed to fit into a notch 212 while another portion of the transverse branch 141 is designed to fit into the housing 113. The sizing of the notches 212, and more particularly the height of the reliefs delimiting the notches is sufficient to immobilize the transverse branch 141 in a longitudinal direction X, when the transverse branch is housed in the notch. On the other hand, because, in this locking configuration, the transverse branch also cooperates with the housing 113 of the frame, the frame 11 is also immobilized in a longitudinal direction X. The transverse branch 141 then serves as a rigid connection, according to the longitudinal direction X, between the rack 21 and the frame 11 and therefore between the sliding board 3 and the retaining device 1. The immobilization of the frame 11 in the other directions Y, Z is achieved by the sliding link resulting from the cooperation between the slides 114 and the rails 22.

En conséquence, pour ajuster la position longitudinale du châssis 11, et donc du dispositif de retenue 1, il suffit d'insérer l'organe de verrouillage 141 dans l'encoche 212 de la crémaillère 21 correspondant au positionnement souhaité.Consequently, to adjust the longitudinal position of the frame 11, and therefore of the retaining device 1, it suffices to insert the locking member 141 into the notch 212 of the rack 21 corresponding to the desired positioning.

Pour pouvoir régler ce positionnement longitudinal, le mécanisme de réglage 10R doit permettre le désengagement de l'organe de verrouillage 141 d'une encoche 212 de la crémaillère 21 alors que la mâchoire mobile 12 et le châssis 11 sont montés coulissants sur l'élément de guidage 2.To be able to adjust this longitudinal positioning, the adjustment mechanism 10R must allow the disengagement of the locking member 141 from a notch 212 of the rack 21 while the movable jaw 12 and the frame 11 are slidably mounted on the locking element. guidance 2.

Dans cet exemple, le désengagement de l'organe de verrouillage 141 d'une encoche 212 se fait en déplaçant la branche transversale 141, selon une direction verticale Z, en s'éloignant du fond de l'encoche, d'une distance supérieure à la hauteur des reliefs 211 délimitant l'encoche concernée. Ainsi, la branche transversale 141 n'est plus bloquée par un relief 211. On peut alors faire coulisser librement le châssis 11, et donc le dispositif de retenue 1, le long de la planche de glisse. Pour figer de nouveau la position du châssis 11, il suffit d'introduire de nouveau la branche transversale 141 dans une nouvelle encoche 212.In this example, the disengagement of the locking member 141 from a notch 212 is effected by moving the transverse branch 141, in a vertical direction Z, away from the bottom of the notch, by a distance greater than the height of the reliefs 211 delimiting the notch concerned. Thus, the transverse branch 141 is no longer blocked by a relief 211. It is then possible to slide the frame 11, and therefore the retaining device 1, freely along the gliding board. To fix the position of the frame 11 again, it suffices to introduce the transverse branch 141 again into a new notch 212.

Pour permettre le désengagement de l'organe de verrouillage 141 d'une encoche 212, il est nécessaire d'avoir un dégagement vertical, selon la direction Z, en vis-à-vis de la branche transversale 141, afin de permettre son déplacement vertical. Dans le cas présent, il faut prévoir un dégagement vertical au niveau du corps 121 mais aussi au niveau de la liaison entre l'organe de liaison 14 et le châssis 11.To allow the disengagement of the locking member 141 from a notch 212, it is necessary to have a vertical clearance, in the direction Z, vis-à-vis the transverse branch 141, in order to allow its vertical displacement. . In the present case, it is necessary to provide a vertical clearance at the level of the body 121 but also at the level of the connection between the connecting member 14 and the frame 11.

Selon le mode de réalisation illustré, le corps 121 de la mâchoire mobile 12 comprend, de chaque côté du corps, une lumière inclinée 1242, prolongeant la lumière horizontale 1241, au niveau de son extrémité postérieure. La lumière horizontale 1241 et la lumière inclinée 1242 définissent un chemin de guidage 124 destiné à recevoir une portion de l'organe de verrouillage 141. Ainsi, le chemin de guidage comprend une lumière horizontale 1241 s'étendant selon une direction longitudinale X prolongée par une lumière inclinée 1242 s'étendant selon une direction d'éloignement par rapport à une surface inférieure 1211 du corps 121 de la mâchoire mobile 12. La lumière inclinée 1242 est préférentiellement inclinée d'un angle α compris entre 30 et 80° par rapport à un plan horizontal XY. La lumière inclinée 1242 est dimensionnée de sorte que lorsque la portion de l'organe de verrouillage 141 en prise avec le chemin de guidage 124 atteint l'extrémité haute de la lumière inclinée 1242, l'organe de verrouillage 141 n'est plus en prise avec une des encoches 212 de la crémaillère 21. Autrement dit, dans cette configuration de déverrouillage, l'organe de verrouillage 141 est désengagé de la crémaillère 21.According to the illustrated embodiment, the body 121 of the movable jaw 12 comprises, on each side of the body, an inclined slot 1242, extending the horizontal slot 1241, at its rear end. The horizontal slot 1241 and the inclined slot 1242 define a guide path 124 intended to receive a portion of the locking member 141. Thus, the guide path comprises a horizontal slot 1241 extending in a longitudinal direction X extended by a inclined light 1242 extending in a direction away from a lower surface 1211 of the body 121 of the movable jaw 12. The inclined light 1242 is preferably inclined at an angle α of between 30 and 80 ° with respect to a horizontal plane XY. The inclined light 1242 is sized so that when the portion of the locking member 141 engaged with the guide path 124 reaches the upper end of the inclined slot 1242, the locking member 141 is no longer in engagement with one of the notches 212 of the rack 21 In other words, in this unlocking configuration, the locking member 141 is disengaged from the rack 21.

Dans cet exemple, pour amener l'organe de verrouillage 141 dans cette configuration de déverrouillage, il suffit de poursuivre le pivotement vers l'arrière de l'actionneur 13, au-delà de la position de libération, configuration correspondant au positionnement de la portion de l'organe de verrouillage 141 à l'intersection entre la lumière horizontale 1241 et la lumière inclinée 1242. En effet, en continuant sa rotation autour de son axe Y13, l'actionneur 13 entraîne, via les branches latérales 142, le déplacement vers l'arrière de l'organe de verrouillage 141 qui va alors suivre le chemin de guidage 124, le long de la lumière inclinée 1242, jusqu'à se désengager de l'encoche 212 avec laquelle elle était en prise.In this example, to bring the locking member 141 into this unlocking configuration, it suffices to continue the rearward pivoting of the actuator 13, beyond the release position, configuration corresponding to the positioning of the portion. of the locking member 141 at the intersection between the horizontal slot 1241 and the inclined slot 1242. In fact, by continuing its rotation around its axis Y13, the actuator 13 drives, via the side branches 142, the movement towards the rear of the locking member 141 which will then follow the guide path 124, along the inclined slot 1242, until it disengages from the notch 212 with which it was engaged.

Ainsi, l'actionneur 13 peut atteindre un troisième positionnement, à savoir, une position de déverrouillage pour laquelle l'actionneur 13 entraîne le déplacement de l'organe de verrouillage 141 de sorte qu'il ne soit plus en prise avec une des encoches 212 de la crémaillère 21.Thus, the actuator 13 can reach a third position, namely, an unlocking position for which the actuator 13 causes the movement of the locking member 141 so that it is no longer in engagement with one of the notches 212. of the rack 21.

Le chemin de guidage 124 ménagé sur le corps 121 de la mâchoire mobile 12 peut présenter d'autres configurations alternatives. Par exemple, le chemin de guidage peut suivre une trajectoire en arc de cercle, en forme d'haricot, en forme de « L » renversé, éventuellement avec dégagement vertical large, plus la largeur de la branche transversale 141. Dans ce dernier cas, le guidage de la branche transversale 141 afin qu'il se désengage de l'encoche 212 peut être assuré par le logement 113.The guide path 124 formed on the body 121 of the movable jaw 12 can have other alternative configurations. For example, the guide path may follow an arcuate, bean-shaped, inverted "L" -shaped path, possibly with wide vertical clearance, plus the width of the transverse branch 141. In the latter case, the guiding of the transverse branch 141 so that it disengages from the notch 212 can be provided by the housing 113.

En conséquence, c'est le guidage de la branche transversale 141 de l'organe de liaison 14 via le chemin de guidage 124 du corps 121 de la mâchoire mobile 12 et/ou via le logement 113, solidaire du châssis 11, qui permet à l'organe de verrouillage 141 de se désengager de l'encoche 212 de la crémaillère 21.Consequently, it is the guiding of the transverse branch 141 of the connecting member 14 via the guide path 124 of the body 121 of the movable jaw 12 and / or via the housing 113, integral with the frame 11, which allows the locking member 141 to disengage from the notch 212 of the rack 21.

On peut envisager d'autres moyens de commande pour désengager l'organe de verrouillage d'une encoche de la crémaillère.It is possible to envisage other control means for disengaging the locking member from a notch in the rack.

Dans cet exemple, le logement 113 forme une encoche, ouverte en haut, ménagée sur un support 115 rapportée sur le châssis 11. Dans ce cas, le châssis 11 comprend un corps 110 sur lequel est assemblé, sans degré de liberté, le support 115. Ici, l'encoche 113 est inclinée selon un angle sensiblement identique à l'angle d'inclinaison α de la lumière inclinée 1242, à savoir entre 30 et 80° par rapport à un plan horizontal XY. Selon ce mode de réalisation, le support 115 porte le logement 113, la mâchoire fixe 111 et une partie des coulisseaux 114. Le support 115 est avantageusement métallique afin d'être plus robuste.In this example, the housing 113 forms a notch, open at the top, provided on a support 115 attached to the frame 11. In this case, the frame 11 comprises a body 110 on which is assembled, without any degree of freedom, the support 115. Here, the notch 113 is inclined at an angle substantially identical to the inclination angle α of the inclined light 1242, namely between 30 and 80 ° with respect to a horizontal plane XY. According to this embodiment, the support 115 carries the housing 113, the fixed jaw 111 and part of the slides 114. The support 115 is advantageously metallic in order to be more robust.

Avantageusement, le logement 113 est dimensionné de sorte que, lorsque l'actionneur 13 est dans sa configuration de déverrouillage 30, la branche transversale 141 est toujours en prise avec le logement 113. Autrement dit, lorsqu'elle atteint l'extrémité postérieure du chemin de guidage 124, la branche transversale 141 coopère toujours avec le logement 113. Ainsi, dans cette configuration, on assure un maintien de l'assemblage entre la mâchoire mobile et le châssis.Advantageously, the housing 113 is dimensioned so that, when the actuator 13 is in its unlocking configuration 30, the transverse branch 141 is still engaged with the housing 113. In other words, when it reaches the rear end of the path guide 124, the transverse branch 141 still cooperates with the housing 113. Thus, in this configuration, the assembly is maintained between the movable jaw and the frame.

Selon un mode de réalisation, le dispositif de retenue 1 comprend un moyen élastique 15 apte à exercer un effort sur l'organe de verrouillage 141 afin de le ramener dans une configuration de coopération avec une des encoches 212 de la crémaillère 21 lorsqu'il est sollicité selon une direction tendant à désengager l'organe de verrouillage de ladite encoche. Le moyen élastique 15 permet de rendre instable la configuration de déverrouillage, tendant ainsi à ramener l'organe de verrouillage 141 vers une configuration de verrouillage plus stable. Cela permet de limiter le risque d'obtenir un dispositif de retenue pouvant coulisser librement en usage, sans action de l'utilisateur. On améliore donc la fiabilité du mécanisme.According to one embodiment, the retaining device 1 comprises an elastic means 15 capable of exerting a force on the locking member 141 in order to bring it back into a configuration of cooperation with one of the notches 212 of the rack 21 when it is urged in a direction tending to disengage the locking member from said notch. The elastic means 15 makes it possible to make the unlocking configuration unstable, thus tending to bring the locking member 141 back to a more stable locking configuration. This makes it possible to limit the risk of obtaining a retaining device which can slide freely in use, without action by the user. The reliability of the mechanism is therefore improved.

Dans cet exemple, le moyen élastique 15 est apte à coopérer avec l'organe de verrouillage 141 lorsque l'actionneur 13 est dans sa configuration de libération. Avantageusement, on utilise le « flexor » 15 décrit précédemment comme moyen élastique pour cette fonction de rappel de l'organe de verrouillage 141.In this example, the elastic means 15 is able to cooperate with the locking member 141 when the actuator 13 is in its release configuration. Advantageously, the “flexor” 15 described above is used as an elastic means for this return function of the locking member 141.

D'autres moyens élastiques sont envisageables pour maintenir l'organe de verrouillage 141 dans une configuration de verrouillage stable.Other elastic means can be envisaged for maintaining the locking member 141 in a stable locking configuration.

Grâce à cette construction, on peut envisager l'utilisation de plaque d'interface ayant un dimensionnement réduit. Par exemple, la largeur L2 de l'élément de guidage 2 peut être comprise entre 25 et 75% de la largeur L3 de la planche de glisse 3. Outre l'allégement, cela permet de ne pas avoir d'éléments dépassant des chants de la planche de glisse et donc d'éléments susceptibles de gêner la glisse. Cela permet aussi de diminuer la position verticale de la chaussure par rapport à la surface de glisse du ski et d'avoir un contact plus direct entre le dispositif de retenue et la surface supérieure du ski. Au final, on peut alors améliorer la performance et/ou les sensations du skieur.Thanks to this construction, it is possible to envisage the use of an interface plate having a reduced dimension. For example, the width L2 of the guide element 2 can be between 25 and 75% of the width L3 of the gliding board 3. In addition to the lightening, this makes it possible not to have elements protruding from the edges of. the gliding board and therefore elements liable to hinder gliding. This also makes it possible to reduce the vertical position of the boot relative to the sliding surface of the ski and to have more direct contact between the retaining device and the upper surface of the ski. In the end, we can then improve the performance and / or the sensations of the skier.

L'invention se transpose également à d'autres constructions de mécanismes de maintien. Par exemple, on peut envisager un mécanisme de maintien minimaliste où l'actionneur et la mâchoire mobile forment une seule pièce. Le document EP-A-2 461 879 illustre un tel mécanisme. Il suffit alors que l'organe de verrouillage coopérant avec une crémaillère soit porté par l'organe de liaison reliant ce sous-ensemble à un point d'accroché fixe par rapport au châssis.The invention is also transposed to other constructions of holding mechanisms. For example, one can envision a minimalist holding mechanism where the actuator and the movable jaw form a single piece. The document EP-A-2 461 879 illustrates such a mechanism. It is then sufficient for the locking member cooperating with a rack to be carried by the connecting member connecting this sub-assembly to a fixed attachment point relative to the frame.

L'invention n'est pas limitée à ces modes de réalisation. Il est possible de combiner ces modes de réalisation.The invention is not limited to these embodiments. It is possible to combine these embodiments.

L'invention n'est pas limitée aux modes de réalisation précédemment décrits mais s'étend à tous les modes de réalisation couverts par les revendications annexées.The invention is not limited to the embodiments described above but extends to all the embodiments covered by the appended claims.
