Description

L'invention concerne un dispositif de fixation de chaussure sur une planche de glisse, particulièrement adapté aux fixations de sécurité pour chaussure de ski, c'est à dire aux dispositifs destinés à maintenir de manière sécurisée une chaussure sur un ski en exerçant une pression sur le talon de la chaussure et en la pressant vers l'avant contre un dispositif de fixation avant appelé butée, en assurant une libération automatique de la chaussure en cas de chute du skieur. Elle concerne aussi un ski sur lequel est fixé un tel dispositif.The invention relates to a device for attaching a boot to a gliding board, particularly adapted to ski boot safety bindings, that is to say devices intended to securely hold a boot on a ski by exerting pressure on a ski boot. the heel of the shoe and pressing it forward against a front fixing device called abutment, ensuring an automatic release of the shoe in case of fall of the skier. It also relates to a ski on which is fixed such a device.

Selon l'art antérieur, décrit par exemple dans le brevet EP0320854 , une fixation de ski comprend une talonnière et une butée pour respectivement coopérer avec l'arrière et l'avant d'une chaussure de ski. Chaque élément de ce dispositif de fixation repose sur une embase placée sur le ski, coopérant avec deux mâchoires dont la fonction est de maintenir la chaussure sur le ski. Ces mâchoires sont reliées à l'embase par l'intermédiaire d'un ressort qui permet de libérer la chaussure quand l'effort exercé par la chaussure dépasse un certain seuil. Plus précisément, la butée permet la rotation latérale des mâchoires selon un axe vertical pour libérer la chaussure en cas de torsion et permet la rotation des mâchoires vers le haut selon un axe horizontal pour libérer la chaussure en cas de chute en arrière du skieur. Pour ces deux mouvements, la libération de la mâchoire est basée sur le même ressort et ne nécessite qu'un seul réglage. Dans beaucoup de chutes du skieur vers l'arrière, ces deux rotations sont en fait combinées, un mouvement de torsion accompagnant la poussée vers le haut, dans une chute appelée "arrière avec torsion". L'apparition sur le marché des skis dit CARVING, skis dont la particularité est de couper le virage, a accru les risques d'accidents liés à ces chutes "arrières avec torsion", qui engendrent souvent des graves lésions au genou. La norme ISO pour les fixations de skis impose comme surcharge admissible à ne pas dépasser pour le couple de torsion à 25% en chutes arrières combinées avec torsion une contrainte arrière de 1.25 fois le couple de torsion réglé. Cette norme est souvent trop tolérante et les fixations actuelles présentent une insuffisance spécifique vis à vis de ces chutes arrières avec torsion.According to the prior art, described for example in the EP0320854 , a ski binding comprises a heel and a stop for respectively cooperating with the rear and the front of a ski boot. Each element of this fixing device is based on a base placed on the ski, cooperating with two jaws whose function is to maintain the boot on the ski. These jaws are connected to the base by means of a spring that releases the shoe when the force exerted by the shoe exceeds a certain threshold. More specifically, the stop allows the lateral rotation of the jaws along a vertical axis to release the shoe in case of torsion and allows the rotation of the jaws upwards along a horizontal axis to release the boot in case of falling behind the skier. For these two movements, the release of the jaw is based on the same spring and requires only one adjustment. In many skier's falls backward, these two rotations are actually combined, a twisting movement accompanying the upward thrust, in a fall called "back with twist". The appearance on the market of skis called CARVING, skis whose particularity is to cut the turn, has increased the risk of accidents related to these falls "back with torsion", which often cause serious lesions to the knee. The ISO standard for fasteners skis imposes as permissible overload not to be exceeded for the torsion torque at 25% in back falls combined with torsion a backward stress of 1.25 times the torsion torque set. This standard is often too tolerant and current fixtures have a specific insufficiency with respect to these falls with torsion.

Un premier objet de la présente invention est un dispositif de fixation d'une chaussure sur une planche de glisse qui améliore la sécurité lors des chutes arrières avec torsion.A first object of the present invention is a device for attaching a boot to a gliding board which improves safety when falling back with torsion.

Un second objet de la présente invention est un dispositif de fixation d'une chaussure sur une planche de glisse qui reste simple et bon marché.A second object of the present invention is a device for attaching a shoe to a gliding board which remains simple and cheap.

L'invention repose sur une butée dont la surface d'appui entre la mâchoire et le corps sur la mâchoire et/ou le corps présente une partie inclinée pour représenter un réglage spécifique du seuil de déclenchement de la fixation pour certaines chutes particulières.The invention is based on a stop whose bearing surface between the jaw and the body on the jaw and / or the body has an inclined portion to represent a specific setting of the release threshold of the attachment for certain particular falls.

Les figures 1 à 9 illustrent schématiquement un mode d'exécution de l'invention pour une fixation de ski.Figures 1 to 9 schematically illustrate an embodiment of the invention for a ski binding.

Comme illustré sur les figures 1 et 2, un tel dispositif repose sur une butée 1 composée d'un corps 2 et de deux mâchoires 3. Les mâchoires 3 sont liées au corps 2 par un tirant placé sur l'axe 8 du corps 2, tirant lui-même relié à un ressort non représenté dont la dureté est réglable par une vis avant 4.As illustrated in FIGS. 1 and 2, such a device rests on a stop 1 composed of a body 2 and two jaws 3. The jaws 3 are connected to the body 2 by a tie rod positioned on the axis 8 of the body 2, pulling itself connected to a not shown spring whose hardness is adjustable by a front screw 4.

Comme illustré sur la figure 3, les mâchoires 3 sont mobiles en rotation selon un axe horizontal 5 qui correspond à l'arête supérieure arrière et transversale du corps 2. En cas de chute arrière, les mâchoires 3 prennent appui sur cet axe 5 pour tourner vers le haut et libérer la chaussure 10.As illustrated in FIG. 3, the jaws 3 are rotatable about a horizontal axis 5 which corresponds to the rear and transverse upper edge of the body 2. In the event of a rear fall, the jaws 3 bear on this axis 5 to rotate up and release the shoe 10.

De manière semblable, les mâchoires 3 sont mobiles en rotation autour d'un axe sensiblement vertical 6 qui correspond à une arête arrière de chaque côté du corps 2. Une telle arête ou axe de rotation vertical 6 est appelé "couteau". La figure 4 illustre la mise en oeuvre d'une telle rotation dans le cas d'une chute en torsion pure, sans effort vers l'arrière.Similarly, the jaws 3 are rotatable about a substantially vertical axis 6 which corresponds to a rear edge of each side of the body 2. Such a vertical edge or axis of rotation 6 is called "knife". FIG. 4 illustrates the implementation of such a rotation in the case of a fall in pure torsion, with no effort towards the rear.

Finalement, le corps 2 présente donc sur sa face arrière une zone d'appui pour les mâchoires 3 en forme de U, qui se compose d'une partie centrale supérieure 5 et de deux parties latérales ou couteaux 6. Chacune de ces parties se trouve dans un même plan sensiblement vertical et transversal à la direction longitudinale selon l'axe 8 de la butée. Selon ce mode d'exécution de l'invention, la zone d'appui en U n'est pas totalement coplanaire mais présente en outre deux parties latérales supérieures 7, correspondant aux angles situés entre les parties 5 et 6, qui présentent la particularité d'être inclinées vers l'avant par rapport au plan défini par les parties 5 et 6. Cette partie 7 se définit plus précisément schématiquement comme une portion de surface triangulaire délimitée par un premier point 7a, en frontière avec la partie latérale verticale 6, un second point 7b, en frontière avec la partie supérieure horizontale et centrale 5, et un troisième point 7c positionnés en avant des points 7a et 7b et plus haut que le point 7a. A partir de chacun des points 7a et 7b, l'inclinaison des axes 5 et 6 change de manière discontinue pour former la partie latérale supérieure 7 inclinée vers l'avant de la butée, par rapport à un plan vertical transversal à la butée, comme cela est particulièrement visible sur les figures 5 à 7. Les mâchoires restent inchangées dans ce mode d'exécution et telles qu'elles sont représentées sur la figure 13 par exemple.Finally, the body 2 thus has on its rear face a bearing zone for the U-shaped jaws 3, which consists of an upper central part 5 and two lateral parts or knives 6. Each of these parts is located in a same plane substantially vertical and transverse to the longitudinal direction along the axis 8 of the stop. According to this embodiment of the invention, the U-shaped bearing zone is not totally coplanar but also has two upper lateral parts 7, corresponding to the angles situated between the parts 5 and 6, which have the characteristic of to be inclined forwards with respect to the plane defined by parts 5 and 6. This part 7 is defined more precisely schematically as a portion of triangular surface delimited by a first point 7a, in border with the vertical lateral part 6, a second point 7b, in border with the horizontal and central upper part 5, and a third point 7c positioned in front of points 7a and 7b and higher than point 7a. From each of the points 7a and 7b, the inclination of the axes 5 and 6 changes discontinuously to form the upper lateral part 7 inclined towards the front of the abutment, with respect to a vertical plane transverse to the abutment, as this is particularly visible in Figures 5 to 7. The jaws remain unchanged in this embodiment and as shown in Figure 13 for example.

La fonction technique des parties inclinées 7 est illustrée en rapport avec les figures 8 et 9 qui représentent le déclenchement de la fixation dans le cas d'une chute arrière avec torsion. Lors d'une telle chute, la mâchoire tend à la fois à une rotation vers le haut et latéralement vers l'extérieur de la butée, et prend naturellement appui sur la partie 7 de la zone d'appui du corps 2. Par sa géométrie décrite ci-dessus, cette partie inclinée 7 rend plus facile la rotation des mâchoires que si elle était dans le plan des autres parties 5 et 6, car elle induit une modification du couple de torsion, exercé par la combinaison de l'effort de la chaussure 10 contrebalancé par l'effet du ressort de la fixation, dans un sens facilitant la libération de la chaussure. Ainsi, par une simple et légère modification de la surface d'appui du corps 2 de la butée, il est possible d'obtenir un réglage différent de l'effort nécessaire au déclenchement de la butée, variable selon le type de chute, et sans modification du réglage du ressort de déclenchement.The technical function of the inclined portions 7 is illustrated in connection with FIGS. 8 and 9 which represent the triggering of the fastening in the case of a torsionally falling back. During such a fall, the jaw tends both to a rotation upwards and laterally to the outside of the abutment, and naturally bears on the part 7 of the bearing zone of the body 2. By its geometry described above, this inclined portion 7 makes it easier to rotate the jaws than if it were in the plane of the other parts 5 and 6, because it induces a modification of the torsion torque, exerted by the combination of the force of the shoe 10 counterbalanced by the effect of the spring of the binding, in a sense facilitating the release of the shoe. Thus, by a simple and slight modification of the bearing surface of the body 2 of the abutment, it is possible to obtain a different adjustment of the force required to trigger the stop, variable according to the type of fall, and without change the setting of the trigger spring.

Selon la géométrie du plan incliné 7, il est possible de prédéfinir les caractéristiques du déclenchement en fonction de la torsion et de l'effort arrière exercés lors d'une chute. Par exemple, plus le point 7b sera déplacé vers le centre de la butée, plus l'effet de l'invention s'appliquera pour une torsion faible. Dans une situation extrême, le concept de l'invention peut ainsi être appliqué à une chute arrière avec une torsion presque nulle. De même, plus le point 7a est bas, restant toutefois toujours au-dessus de l'axe du tirant lié au ressort de la butée, c'est à dire l'axe longitudinal 8 de la butée, plus l'effet de l'invention s'appliquera pour un effort vertical faible sur les mâchoires en cas de chute vers l'arrière. Enfin, l'angle d'inclinaison de la surface 7, soit le positionnement du point 7c, définit aussi une intensité de la baisse du couple de torsion exercé. L'homme du métier adaptera donc la forme de la surface d'appui entre les mâchoires 3 et le corps 2 selon les besoins de chaque application particulière.According to the geometry of the inclined plane 7, it is possible to predefine the characteristics of the trigger as a function of the torsion and the back force exerted during a fall. For example, the more the point 7b is moved toward the center of the stop, the more the effect of the invention will apply for a weak twist. In an extreme situation, the concept of the invention can thus be applied to a rear drop with almost no torsion. Similarly, the point 7a is lower, however still remaining above the axis of the tie rod linked to the spring of the stop, that is to say the longitudinal axis 8 of the abutment, plus the effect of the invention will apply for a low vertical force on the jaws in case of falling backwards. Finally, the angle of inclination of the surface 7, ie the positioning of the point 7c, also defines an intensity of the drop in the torsion torque exerted. Those skilled in the art will therefore adapt the shape of the bearing surface between the jaws 3 and the body 2 according to the needs of each particular application.

Les figures 10 à 12 illustrent le mode d'exécution précédent de l'invention, sur une butée dans laquelle les mâchoires ne sont pas représentées pour des raisons de meilleure lisibilité des éléments essentiels de l'invention. La figure 13 représente une mâchoire 3 de la butée dont les surfaces d'appui 5' et 6' sont destinées à venir en contact sur les surfaces d'appui 5 et 6 du corps 2.Figures 10 to 12 illustrate the previous embodiment of the invention, on a stop in which the jaws are not shown for reasons of better readability of the essential elements of the invention. FIG. 13 represents a jaw 3 of the abutment whose bearing surfaces 5 'and 6' are intended to come into contact on the bearing surfaces 5 and 6 of the body 2.

Selon une variante d'exécution représentée sur la figure 14, le concept de l'invention peut être mis en oeuvre par une modification de la surface des mâchoires 3 destinée à venir en contact avec le corps 2 de la butée, la zone d'appui sur le corps 2 restant alors inchangée, de manière à obtenir par équivalence les mêmes résultats que ceux décrits précédemment. Dans cette variante de réalisation, la surface d'appui de la mâchoire 3 présente une surface inclinée vers l'arrière de la butée.According to an alternative embodiment shown in FIG. 14, the concept of the invention can be implemented by a modification of the surface of the jaws 3 intended to come into contact with the body 2 of the abutment, the bearing zone on the body 2 remaining unchanged, so as to obtain by equivalence the same results as those described above. In this variant embodiment, the bearing surface of the jaw 3 has a surface inclined towards the rear of the abutment.

En fait, dans tous les cas, une des surfaces d'appui au moins du corps 2 ou des mâchoires 3 présente une surface avec une partie inclinée, et donc une surface d'appui globalement non plane. Selon les modes d'exécution décrits précédemment, la surface d'appui présente au moins une partie d'inclinaison discontinue, différente par rapport à l'ensemble de la surface. Toutefois, le même concept peut être mis en oeuvre avec des surfaces courbes, une partie 7, 7' se distinguant toujours par rapport à l'ensemble de la surface d'appui par une inclinaison différente dans le but de modifier le réglage du déclenchement de la fixation pour un type spécifique de chute.In fact, in all cases, one of the bearing surfaces of at least the body 2 or jaws 3 has a surface with an inclined portion, and therefore a generally non-planar bearing surface. According to the embodiments described above, the bearing surface has at least one portion of discontinuous inclination, different from the entire surface. However, the same concept can be implemented with curved surfaces, a part 7, 7 'still being distinguished with respect to the whole of the bearing surface by a different inclination for the purpose of modifying setting the release trigger for a specific type of fall.

De plus, ce concept a été mis en oeuvre pour un réglage spécifique du déclenchement d'une fixation en cas de chute arrière avec torsion mais il peut s'appliquer pour tout type de chute. Il peut aussi être mis en oeuvre pour un réglage dans un sens opposé, c'est à dire dans le but d'augmenter le seuil de déclenchement de certains types de chutes.In addition, this concept has been implemented for a specific adjustment of the release of a fixation in the event of a fall with torsion but it can be applied for any type of fall. It can also be implemented for a setting in an opposite direction, that is to say in order to increase the trigger threshold of certain types of falls.

Claims (9)

  1. A toe-piece for attaching a boot to a sliding board, comprising a body (2) and at least one jaw (3) which is rotationally movable about a substantially horizontal axis (5) in accordance with a first bearing on the body (2) for release in the event of a backward fall and rotationally movable about a substantially vertical axis (6) in accordance with a second bearing on the body (2) for release in the event of torsion, wherein the bearing surface between the jaw (3) and the body (2) on the jaw (3) and/or the body (2) has an inclined part (7, 7') to represent a specific setting of the release threshold of the binding for certain particular falls.
  2. The attachment toe-piece as claimed in claim 1, wherein the bearing surface (5, 6, 7; 5', 6', 7') between the jaw (3) and the body (2) on the jaw (3) and/or the body (2) is substantially non-coplanar.
  3. The attachment toe-piece as claimed in claim 1 or 2, wherein the bearing surface (5, 6, 7; 5', 6', 7') between the jaw (3) and the body (2) on the jaw (3) and/or the body (2) has a discontinuous inclination in relation to a vertical and/or horizontal direction to form the inclined part (7, 7').
  4. The attachment toe-piece as claimed in one of the preceding claims, wherein the horizontal axis (5) corresponds to a central, transverse, horizontal upper rear edge of the body (2), and which comprises two vertical axes (6) corresponding to a lateral, vertical lower rear edge of the body (2), the inclined part (7) being a surface which is intermediate between the horizontal axis (5) and the vertical axes (6) of the body (2) and oriented toward the front of the toe-piece.
  5. The attachment toe-piece as claimed in one of the preceding claims, wherein the inclined part (7) has an inclination toward the front of the toe-piece from a point (7a) of the vertical lateral axis (6) located above the longitudinal axis (8) of the toe-piece bearing a spring/rod assembly.
  6. The attachment toe-piece as claimed in the preceding claim, wherein the inclined part (7) has an inclination toward the front of the toe-piece from a point (7b) of the horizontal lateral axis (5) to facilitate the release of the binding in the event of a backward fall with torsion.
  7. The attachment toe-piece as claimed in one of the claims 1 to 3, wherein the jaws (3) have a horizontal upper anterior edge (5') a substantially vertical anterior lateral edge (6'), the inclined part (7') being a surface which is intermediate between the horizontal axis (5') and the vertical axis (6') of the jaws (3) and oriented toward the rear of the toe-piece.
  8. An attachment device comprising a toe-piece as claimed in one of the preceding claims.
