Description

La présente invention a pour objet un dispositif de fixation d'une chaussure sur un ski de fond.The present invention relates to a device for attaching a boot to a cross-country ski.

Une fixation de ski de fond comprend une butée assurant le blocage de l'extrémité avant de la chaussure sur le ski, tout en laissant libre le talon, ce qui permet au skieur de décoller les talons par rapport aux skis pour réaliser le mouvement d'avance de ceux-ci.A cross-country binding includes a stop ensuring the blocking of the front end of the boot on the ski, while leaving the heel free, which allows the skier to take off the heels relative to the skis to achieve the movement of advance of these.

Pour permettre ce pivotement de la chaussure tout en bénéficiant d'une bonne rigidité de la semelle de celle-ci, il est connu par le document EP-A-0167462, de réaliser une fixation comportant un étrier dont la partie centrale est articulée sur un axe transversal au ski, et dont les branches sont conformées pour permettre l'emboîtement d'une partie complémentaire ménagée à l'extrémité avant de la chaussure. Cet étrier est lui-même équipé de moyens d'immobilisation de la chaussure.To allow this pivoting of the shoe while benefiting from a good rigidity of the sole thereof, it is known from document EP-A-0167462 to produce a binding comprising a stirrup the central part of which is articulated on a axis transverse to the ski, and the branches of which are shaped to allow the interlocking of a complementary part formed at the front end of the boot. This stirrup is itself equipped with means for immobilizing the boot.

Toutefois, le dispositif de verrouillage décrit dans ce document est relativement peu pratique à mettre en oeuvre, puisque nécessitant des interventions manuelles tant pour la fermeture que pour l'ouverture de la fixation.However, the locking device described in this document is relatively impractical to implement, since it requires manual intervention both for closing and for opening the binding.

La présente invention vise à fournir un dispositif de fixation de ce type, comportant des moyens de verrouillage perfectionnés.The present invention aims to provide a fastening device of this type, comprising improved locking means.

A cet effet, le dispositif de fixation qu'elle concerne, du type comprenant un étrier dont la partie centrale est articulée sur un axe transversal au ski, et dont les branches sont conformées pour permettre l'emboîtement d'une partie complémentaire ménagée à l'extrémité avant de la chaussure, cet étrier étant en outre équipé de moyens d'immobilisation de l'extrémité avant de la chaussure, est caractérisé en ce que ces moyens d'immobilisation sont constitués:

  • ― par un levier de verrouillage monté pivotant sur l'étrier autour d'un axe transversal au ski, entre une position de fermeture dans laquelle une partie du levier prend appui sur la face supérieure de l'extrémité avant de la chaussure et une position d'ouverture dans laquelle le levier laisse libre l'accès à l'étrier,
  • ― par une gâchette montée pivotante sur le levier de verrouillage autour d'un axe transversal au ski, comportant deux cames venant en contact avec les bords avant de l'étrier formant des rampes dont le profil est tel que lorsque la gâchette est basculée vers l'avant le levier de verrouillage est en position d'ouverture et que lorsque la gâchette est basculée vers l'arrière le levier de verrouillage est en position de fermeture,
  • ― et par des moyens élastiques reliant l'étrier et le levier et agissant sur celui-ci dans un sens de fermeture, selon un plan passant sensiblement par l'axe d'articulation de la gâchette sur le levier et de part et d'autre duquel se trouvent les points de contact entre la gâchette et l'étrier, respectivement en position d'ouverture et en position de fermeture.
To this end, the fastening device that it relates to, of the type comprising a stirrup, the central part of which is articulated on an axis transverse to the ski, and the branches of which are shaped to allow the fitting of a complementary part arranged the front end of the shoe, this stirrup being furthermore equipped with means for immobilizing the front end of the shoe, is characterized in that these means of immobilization consist of:
  • - by a locking lever pivotally mounted on the stirrup about an axis transverse to the ski, between a closed position in which a part of the lever is supported on the upper face of the front end of the boot and a position d '' opening in which the lever leaves free access to the stirrup,
  • - By a trigger pivotally mounted on the locking lever around an axis transverse to the ski, comprising two cams coming into contact with the front edges of the stirrup forming ramps whose profile is such that when the trigger is tilted towards the before the locking lever is in the open position and when the trigger is tilted backwards the locking lever is in the closed position,
  • - And by elastic means connecting the stirrup and the lever and acting on it in a closing direction, in a plane passing substantially through the axis of articulation of the trigger on the lever and on both sides which are the points of contact between the trigger and the stirrup, respectively in the open position and in the closed position.

Les mouvements d'ouverture et de fermeture de la fixation sont obtenus par action sur la seule gâchette dont le basculement vers l'avant ou l'arrière provoque le basculement du levier vers sa position d'ouverture ou sa position de fermeture respectivement. Ces mouvements sont effectués très facilement, sans que l'ensemble puisse demeurer dans un état stable intermédiaire, puisque lorsque la gâchette est actionnée dans un sens, elle poursuit automatiquement son mouvement jusqu'en fin de course, sous l'action des moyens élastiques, dès que les points d'appui de la gâchette sur l'étrier sont passés de l'autre côté du plan d'action des moyens élastiques, par rapport au côté duquel ils se trouvaient initialement.The movements of opening and closing of the binding are obtained by action on the only trigger, the tilting forwards or backwards causes the lever to tilt to its open position or its closed position respectively. These movements are carried out very easily, without the assembly being able to remain in an intermediate stable state, since when the trigger is actuated in one direction, it automatically continues its movement until the end of the race, under the action of elastic means, as soon as the support points of the trigger on the stirrup have passed to the other side of the action plan of the elastic means, relative to the side on which they were initially.

Avantageusement, la gâchette est équipée à son extrémité inférieure d'au moins un doigt tourné vers l'arrière et destiné à venir prendre appui sous l'extrémité avant de la partie de la chaussure venant s'emboîter dans l'étrier.Advantageously, the trigger is equipped at its lower end with at least one finger turned towards the rear and intended to come to bear under the front end of the part of the shoe which fits into the stirrup.

Lors de l'emboîtement de l'extrémité avant de la chaussure dans l'étrier, celle-ci prend appui sur le doigt de la gâchette, provoquant un pivotement de celle-ci vers l'arrière, et par suite un pivotement du levier vers sa position de verrouillage sous l'action conjointe des moyens élastiques. Cette fixation est donc à chaussage automatique. Pour réaliser le déverrouillage du levier, il suffit de faire pivoter la gâchette vers l'avant à la main ou à l'aide de la pointe d'une canne de ski, mouvement s'accompagnant d'un pivotement du levier vers sa position d'ouverture, et d'un déplacement vers le haut du doigt solidaire de la gâchette, qui soulève la partie avant de la chaussure et facilite sa sortie hors de l'étrier.When the front end of the shoe is fitted into the stirrup, the latter bears on the trigger finger, causing the latter to pivot backwards, and consequently the lever to pivot towards its locking position under the joint action of elastic means. This binding is therefore self-fitting. To unlock the lever, simply rotate the trigger forward by hand or with the tip of a ski pole, movement accompanied by a pivoting of the lever to its position d opening, and an upward movement of the finger secured to the trigger, which lifts the front part of the shoe and facilitates its exit from the stirrup.

Selon une forme d'exécution de ce dispositif, le levier de verrouillage possède une forme générale de U, dont les branches sont articulées chacune sur une branche de l'étrier, et dont la partie centrale forme une surface d'appui sur la face supérieure de la partie avant de la chaussure.According to one embodiment of this device, the locking lever has a general U shape, the branches of which are each articulated on a branch of the stirrup, and the central part of which forms a bearing surface on the upper face of the front part of the shoe.

De préférence, la surface d'appui du levier sur la face supérieure de la partie avant de la chaussure est en forme de tronçon de surface cylindrique d'axe transversal au ski.Preferably, the bearing surface of the lever on the upper face of the front part of the shoe is in the form of a surface section. cylindrical with transverse axis to the ski.

Cette caractéristique assurant un appui du levier sur la chaussure selon une génératrice d'une surface cylindrique, procure un excellent verrouillage, quelle que soit l'inclinaison de la face supérieure d'appui de la chaussure, d'autant plus que le dispositif assure une compensation de l'épaisseur de la semelle de la chaussure par un basculement plus ou moins important du levier.This characteristic ensuring a support of the lever on the shoe according to a generatrix of a cylindrical surface, provides an excellent locking, whatever the inclination of the upper support face of the shoe, all the more that the device ensures a compensation for the thickness of the sole of the shoe by a more or less significant tilting of the lever.

Selon une autre forme d'exécution de ce dispositif c'est, à l'inverse, la surface d'appui de l'avant de la chaussure qui présente un tronçon de surface cylindrique d'axe transversal au ski et coopère avec un levier dont la surface d'appui est plane. Cette caractéristique procurera les mêmes avantages que décrits précédemment.According to another embodiment of this device, it is, conversely, the bearing surface of the front of the boot which has a cylindrical surface section of axis transverse to the ski and cooperates with a lever whose the support surface is flat. This feature will provide the same benefits as described above.

Selon une autre caractéristique de l'invention, l'extrémité avant du levier comporte deux ailes délimitant avec la partie centrale du levier une chape servant au montage de l'axe d'articulation de la gâchette.According to another characteristic of the invention, the front end of the lever comprises two wings delimiting with the central part of the lever a yoke used for mounting the hinge pin of the trigger.

Conformément à une première possibilité, les moyens élastiques sont constitués par une pièce en matière synthétique possédant une forme générale de U, dont les extrémités des branches sont montées articulées sur les ailes de l'étrier autour d'un axe transversal au ski, et dont la partie centrale est en appui sur la face avant du levier au niveau de l'axe d'articulation de la gâchette sur celui-ci.In accordance with a first possibility, the elastic means consist of a piece of synthetic material having a general shape of U, the ends of the branches of which are articulated on the wings of the stirrup around an axis transverse to the ski, and of which the central part is supported on the front face of the lever at the trigger hinge pin thereon.

Conformément à une autre possibilité, les moyens élastiques sont constitués par deux bandes de matière synthétique disposées parallèlement à l'axe du ski, dont les extrémités sont fixées d'une part sur l'étrier et d'autre part sur le levier.According to another possibility, the elastic means consist of two strips of synthetic material arranged parallel to the axis of the ski, the ends of which are fixed on the one hand to the stirrup and on the other hand to the lever.

Selon une forme préférée d'exécution, la gâchette comporte un doigt de commande unique disposé sur l'axe longitudinal du ski et destiné à pénétrer dans un évidement ménagé à cet effet dans la face inférieure de l'extrémité avant de la chaussure. Le choix de la profondeur de cet évidement permet de régler les décalages à l'ouverture et à la fermeture entre l'actionnement de la gâchette et le mouvement de mise en place de la chaussure.According to a preferred embodiment, the trigger comprises a single control finger disposed on the longitudinal axis of the ski and intended to penetrate into a recess provided for this purpose in the underside of the front end of the boot. The choice of the depth of this recess makes it possible to adjust the offsets at the opening and at the closing between the actuation of the trigger and the movement of fitting the shoe.

Il résulte de la structure de ce dispositif, et notamment de la disposition sensiblement horizontale des moyens élastiques, une grande compacité notamment dans le sens de la hauteur.It results from the structure of this device, and in particular from the substantially horizontal arrangement of the elastic means, a great compactness in particular in the height direction.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit en référence au dessin schématique annexé représentant, à titres d'exemples non limitatifs, deux formes d'exécution de ce dispositif de fixation d'une chaussure sur un ski de fond:

  • Figure 1 est une vue en perspective d'un premier dispositif en position ouverte;
  • Figure 2 en est une vue de dessus;
  • Figures 3 et 4 sont deux vues de côté, partiellement en coupe, de ce dispositif, respectivement, en position ouverte et en position de verrouillage d'une chaussure;
  • Figures 5 et 6 sont deux vues en position ouverte d'une variante de ce dispositif, respectivement, en perspective et de côté.
In any case, the invention will be clearly understood with the aid of the description which follows with reference to the appended schematic drawing representing, by way of nonlimiting examples, two embodiments of this device for attaching a boot to a cross-country ski:
  • Figure 1 is a perspective view of a first device in the open position;
  • Figure 2 is a top view;
  • Figures 3 and 4 are two side views, partially in section, of this device, respectively, in the open position and in the locking position of a shoe;
  • Figures 5 and 6 are two views in the open position of a variant of this device, respectively, in perspective and from the side.

La figure 1 représente un ski de fond 2 comportant, sur sa face supérieure, une nervure longitudinale 3 de section trapézoïdale, traversée par un axe transversal 4 servant au montage articulé du dispositif de fixation de la chaussure.FIG. 1 represents a cross-country ski 2 comprising, on its upper face, a longitudinal rib 3 of trapezoidal section, crossed by a transverse axis 4 serving for the articulated mounting of the device for fixing the boot.

Ce dispositif comprend un étrier 5 comportant une partie centrale parallèle au plan du ski et deux branches 6 qui en sont perpendiculaires servant, d'une part au montage de l'axe 4 et, d'autre part à la fixation de la chaussure. A cet effet, les branches 6 présentent, sur leurs faces en regard, deux nervures 7 d'orientation générale verticale lorsque la butée est au repos, ces nervures servant à l'emboîtement de rainures complémentaires 8 ménagées à l'extrémité avant 9 de la semelle d'une chaussure 10.This device comprises a stirrup 5 comprising a central part parallel to the plane of the ski and two branches 6 which are perpendicular serving thereon, on the one hand for mounting the axis 4 and, on the other hand for fixing the boot. To this end, the branches 6 have, on their opposite faces, two ribs 7 of generally vertical orientation when the stop is at rest, these ribs serving to fit complementary grooves 8 formed at the front end 9 of the sole of a shoe 10.

Sur les branches 6 de l'étrier 5, sont articulées, autour d'un axe 12 transversal au ski, les branches 13 d'un levier 14 en forme générale de U dont la partie centrale comporte une surface d'appui sur la face supérieure 16 de la partie avant 9 de la chaussure, en forme de tronçon de surface cylindrique 15.On the branches 6 of the stirrup 5, are articulated about an axis 12 transverse to the ski, the branches 13 of a lever 14 in the general shape of U whose central part has a bearing surface on the upper face 16 of the front part 9 of the shoe, in the form of a section of cylindrical surface 15.

L'extrémité avant du levier 14 comporte deux ailes parallèles 17, tournées vers l'avant servant au montage, transversalement au ski, d'un axe de rotation 18 d'une gâchette 19. Cette gâchette 19 comporte deux cames 20 tournées vers l'arrière, prenant appui contre les bords avant 22 des deux branches de l'étrier, qui forment des rampes de guidage. La longueur des cames 20 et le profil des bords 22 sont tels que, lorsque la gâchette 19 est basculée vers l'avant, elle entraîne le levier 14 en position d'ouverture et que lorsque la gâchette 19 est basculée vers l'arrière, elle entraîne le levier 14 vers sa position de fermeture.The front end of the lever 14 comprises two parallel wings 17, facing forwards, used for mounting, transversely to the ski, an axis of rotation 18 of a trigger 19. This trigger 19 comprises two cams 20 facing towards rear, bearing against the front edges 22 of the two branches of the stirrup, which form guide ramps. The length of the cams 20 and the profile of the edges 22 are such that, when the trigger 19 is tilted forward, it drives the lever 14 in the open position and that when the trigger 19 is tilted back, it drives the lever 14 to its closed position.

La gâchette est équipée, dans sa partie centrale et à son extrémité inférieure, d'un doigt 23 tourné vers l'arrière. Ce doigt est destiné, lors de la fixation de la chaussure sur le ski, à venir prendre appui dans le fond d'un évidement 24 débouchant dans la face inférieure de l'extrémité avant 9 de la chaussure.The trigger is equipped, in its central part and at its lower end, with a finger 23 turned towards the rear. This finger is intended, when attaching the boot to the ski, to come to bear in the bottom of a recess 24 opening into the underside of the front end 9 of the boot.

Dans le dispositif représenté aux figures 1 à 4, les moyens élastiques sont constitués par une pièce en matière synthétique 25 en forme générale de U dont les extrémités des branches 26 sont montées sur les branches 6 de l'étrier avec possibilité de pivotement autour d'un axe 27 transversal au ski, et dont la partie centrale 28 prend appui sur le levier 14 au niveau de l'axe d'articulation 18 de la gâchette 19 sur celui-ci. L'axe 27 est disposé de telle façon que le plan d'action des moyens élastiques soit situé entre les points de contact des cames 20 sur les rampes 22 de l'étrier, respectivement, en position ouverte et fermée de la fixation.In the device shown in FIGS. 1 to 4, the elastic means consist of a plastic part 25 in the general shape of a U, the ends of the arms 26 of which are mounted on the arms 6 of the stirrup with the possibility of pivoting around an axis 27 transverse to the ski, and the central part 28 of which bears on the lever 14 at the level of the articulation axis 18 of the trigger 19 on the latter. The axis 27 is arranged so that the plane of action of the elastic means is located between the contact points of the cams 20 on the ramps 22 of the stirrup, respectively, in the open and closed position of the binding.

Le fonctionnement de ce dispositif est le suivant.The operation of this device is as follows.

Pour réaliser la fixation d'une chaussure 10 sur le ski, il suffit à, l'utilisateur de présenter sa chaussure au-dessus du dispositif qui se trouve en position ouverte comme montré à la figure 3. La chaussure est alors déplacée de haut en bas pour réaliser l'engagement des rainures 8 sur les nervures 7 de l'étrier 5, mouvement au cours duquel l'extrémité avant de la chaussure prend appui sur le doigt 23 de la gâchette 19. Cet appui provoque un basculement vers l'arrière de la gâchette 19 et, par suite, du levier de verrouillage 14, ce mouvement étant favorisé par l'action des moyens élastiques 25 dès que le point d'appui des cames 20 sur les rampes 22 est passé de l'autre côté du plan d'action des moyens élastiques. Ce sont les moyens élastiques qui assurent le maintien en position de verrouillage du dispositif, représentée à la figure 4, ce verrouillage étant obtenu par- appui de la surface cylindrique 15 du levier 14 contre la face supérieure 16 de la partie avant de la chaussure.To secure a boot 10 on the ski, the user need only present his boot above the device which is in the open position as shown in FIG. 3. The boot is then moved up and down. bottom to achieve the engagement of the grooves 8 on the ribs 7 of the stirrup 5, movement during which the front end of the shoe is supported on the finger 23 of the trigger 19. This support causes a rearward tilting of the trigger 19 and, consequently, of the locking lever 14, this movement being favored by the action of the elastic means 25 as soon as the fulcrum of the cams 20 on the ramps 22 has passed on the other side of the plane of action of elastic means. These are the elastic means which maintain the locking position of the device, shown in FIG. 4, this locking being obtained by pressing the cylindrical surface 15 of the lever 14 against the upper face 16 of the front part of the shoe.

Pour désolidariser la chaussure du ski, il suffit à l'utilisateur de faire basculer la gâchette vers l'avant, par exemple par appui de la pointe d'une canne de ski dans un évidement 29 ménagé sur la gâchette 19. Le pivotement de la gâchette 19 se traduit par le pivotement du levier 14 vers sa position d'ouverture ainsi que par un pivotement du doigt 23 vers le haut, qui réalise ainsi l'éjection de la chaussure hors de la fixation. La fin de ce mouvement est favorisée par le passage de l'autre côté du plan d'action des moyens élastiques, qui assurent également le maintien du dispositif en position ouverte.To separate the boot from the ski, the user just has to tilt the trigger forward, for example by pressing the tip of a ski pole in a recess 29 made on the trigger 19. The pivoting of the trigger 19 results in the pivoting of the lever 14 towards its open position as well as in a pivoting of the finger 23 upwards, which thus ejects the shoe from the binding. The end of this movement is favored by the passage on the other side of the action plan of the elastic means, which also ensure that the device is kept in the open position.

Les figures 5 et 6 représentent une variante de réalisation de ce dispositif dans laquelle les mêmes éléments sont désignés par les mêmes références que précédemment, la seule différence résidant dans le fait que les moyens élastiques sont constitués non pas par une pièce en forme d'étrier ceinturant la partie avant du levier de verrouillage, mais par deux bandes de matière synthétique 30 disposées parallèlement à l'axe du ski, dont les extrémités sont fixées, d'une part sur les branches 6 de l'étrier 5 et, d'autre part sur les branches 13 du levier 14.Figures 5 and 6 show an alternative embodiment of this device in which the same elements are designated by the same references as above, the only difference residing in the fact that the elastic means are constituted not by a stirrup-shaped part encircling the front part of the locking lever, but by two strips of synthetic material 30 arranged parallel to the axis of the ski, the ends of which are fixed, on the one hand to the arms 6 of the stirrup 5 and, on the other hand to the arms 13 of the lever 14.

Le fonctionnement de ce dispositif est exactement le même que celui du dispositif décrit précédemment.The operation of this device is exactly the same as that of the device described above.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un dispositif de fixation d'une chaussure sur un ski, de conception simple, d'une grande compacité et d'une utilisation très pratique, puisque permettant un chaussage automatique et une éjection de la chaussure lors du déchaussage.As is clear from the above, the invention brings a great improvement to the existing technique by providing a device for attaching a boot to a ski, of simple design, with great compactness and very practical use, since allowing an automatic putting on and an ejection of the shoe during the heaving.

Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de ce dispositif, décrites ci-dessus à titre d'exemples; elle en embrasse, au contraire, toutes les variantes de réalisation. C'est ainsi notamment que ce dispositif pourrait être monté non pas sur un ski à nervure longitudinale mais sur un ski de section rectangulaire ou encore que la gâchette pourrait comporter non pas un doigt de commande central, mais deux doigts de commande latéraux sans que l'on sorte pour autant du cadre de l'invention.It goes without saying that the invention is not limited to the sole embodiments of this device, described above by way of examples; on the contrary, it embraces all of its variant embodiments. Thus, in particular, this device could be mounted not on a ski with a longitudinal rib but on a ski of rectangular section, or even that the trigger could comprise not a central control finger, but two lateral control fingers without the 'We therefore go beyond the scope of the invention.

C'est ainsi que les moyens élastiques 25 pourraient être constitués par une barre de torsion jouant en même temps le rôle d'axe 12, ou encore par un ressort à épingle agissant entre le levier 14 et l'étrier 5, ou encore par tout autre moyen mécaniquement connu.Thus the elastic means 25 could be constituted by a torsion bar playing at the same time the role of axis 12, or by a pin spring acting between the lever 14 and the stirrup 5, or by any other mechanically known means.
