Abstract

A plate (13) fixed to the front side of the ski (1) comprises two plane parts (12) constituting a clevis supporting a spindle (9). On the other end is a stop (2) and a lever (3) for retaining or releasing a long plate (8) acting as the boot support. The long plate has in its rear part a heelpiece (6) connected to the heel plate (5) which holds the rear of a boot (7) by its sole (4). The heel plate can be fixed in different places on the length of the plate to accommodate different boot lengths. In its front part the long plate has a front stop formed by a jaw (10) and a safety system (11) for holding the boot. The plate pivots about the spindle which is at a height (H) above the plane of the plate so that the pivoting axis is as near as possible to the boot upper part The ski fixing reduces the skier's forward effort by creating a force which tends to propel the skier forwards.

Description

L'invention à pour objet une fixation de ski de randonnée.The invention relates to a ski touring binding.

Il est connu que pour la pratique du ski de randonnée les skis doivent être équipés de fixations permettant à volonté, soit d'immobiliser la chaussure sur le ski, ce qui est nécessaire en position descente, soit au contraire de permettre au talon de la chaussure d'effectuer un mouvement ascendant et descendant par rapport au ski, pour favoriser l'avance du skieur lors de ses déplacements à plat ou en montée.It is known that for the practice of ski touring skis must be equipped with bindings allowing at will, either to immobilize the boot on the ski, which is necessary in the downhill position, or on the contrary to allow the heel of the boot to carry out an upward and downward movement with respect to the ski, to favor the advance of the skier during his displacements flat or uphill.

Parmi les fixations de randonnée utilisées actuellement celles présentant le plus d'avantages sont celles dites à plaques. Il s'agit de fixations comprenant un élément allongé qui peut être une plaque comportant ou non des ouvertures ou être des tiges métalliques et, est articulé par son bord transversal avant librement autour d'un axe situé transversalement par rapport au ski. Cette plaque comprend à l'avant une butée contre laquelle prend appui la pointe de la chaussure et à l'arrière une talonnière destinée à solidariser la chaussure avec la plaque. Des moyens de sécurité sont prévus tant sur la butée avant que sur la talonnière arrière pour permettre le dégagement automatique de la chaussure lorsque des efforts dangereux pour la jambe du skieur s'exercent soit en direction de l'avant, soit en direction latérale, c'est à dire en torsion. De plus pour permettre à la plaque sur laquelle est fixée la chaussure de pouvoir, soit être libre en articulation autour de son axe transversal avant (position de plat ou de montée), soit d'être immobilisée sur le ski (position descente), il existe plusieurs dispositifs, qui dans l'ensemble donne satisfaction.Among the touring bindings currently used, those presenting the most advantages are those known as plates. These are bindings comprising an elongated element which can be a plate with or without openings or be metal rods and, is articulated by its front transverse edge freely around an axis located transversely to the ski. This plate comprises at the front a stop against which the point of the shoe bears and at the rear a heel piece intended to secure the shoe with the plate. Safety means are provided both on the front stop and on the rear heel to allow automatic release of the boot when efforts dangerous to the skier's leg are exerted either in the front direction or in the lateral direction, c 'is to say in torsion. In addition to allow the plate on which the power boot is fixed, either to be free to articulate around its front transverse axis (flat or uphill position), or to be immobilized on the ski (downhill position), it There are several devices, which on the whole are satisfactory.

La plupart des fixations de randonnées connues donnent pleinement satisfaction du point de vue de leur fonctionnement mécanique. Mais en ce qui a trait à leur utilisation elles présentent certains inconvénients, notamment lorsque le skieur soulève son talon il se crée une force qui a tendance à faire reculer le ski, ce qui diminue la vitesse d'avancement et augmente l'effort du skieur.Most of the known hiking bindings give full satisfaction from the point of view of their mechanical functioning. But with regard to their use, they have certain drawbacks, in particular when the skier lifts his heel, a force is created which tends to make the ski move back, which decreases the speed of advance and increases the effort of the skier. .

L'invention a pour but de fournir une fixation de randonnée qui ne présente pas les inconvénients des fixations de randonnée connues cités ci-devant. C'est à dire une fixation de ski de randonnée, qui présenterait une diminution de l'effort du skieur et une augmentation de son rendement lors de l'avancement.The object of the invention is to provide a hiking binding which does not have the drawbacks of the known hiking bindings mentioned above. That is to say a ski touring binding, which would present a reduction in the effort of the skier and an increase in his performance during advancement.

La fixation de ski de randonnée, selon l'invention, atteint ce but, et comporte un élément allongé compris dans un plan servant de support à une butée avant et à une talonnière arrière destinées à maintenir une chaussure et articulé autour d'un axe transversal relativement au ski à sa partie avant du côté de la butée, des moyens permettant, soit de maintenir l'élément allongé lié au ski pour la position descente, soit de la laisser libre en rotation autour de son axe avant pour la position montée, caractérisé en ce que l'axe de rotation de l'élément allongé est disposé au-dessus du plan de l'élément allongé.The ski touring binding, according to the invention, achieves this goal, and comprises an elongated element included in a plane serving as support for a front stop and a rear heel intended to hold a shoe and articulated around a transverse axis. relative to the ski at its front part on the side of the stop, means making it possible either to keep the elongated element linked to the ski for the descent position, or to leave it free to rotate about its front axis for the mounted position, characterized in that the axis of rotation of the elongate member is disposed above the plane of the elongate member.

En effet, la titulaire a constaté que si l'on déplaçait en hauteur relativement au plan de la plaque, l'axe de rotation de cette dernière, il se créait lorsque le skieur soulevait et abaissait son talon une force de réaction dirigée vers l'avant, c'est-à dire une force qui a tendance à projeter le ski vers l'avant. Cette disposition de l'axe représente une sensible diminution de l'effort du skieur et une augmentation du rendement lors de l'avancement.Indeed, the holder noted that if one moved in height relatively to the plane of the plate, the axis of rotation of the latter, it was created when the skier raised and lowered his heel a reaction force directed towards the forward, that is to say a force which tends to throw the ski forward. This arrangement of the axis represents a sensitive decrease in the effort of the skier and an increase in yield during advancement.

L'invention sera mieux comprise à l'aide de la description qui suit, en référence aux dessins schématiques annexés représentant, à titre d'exemple non limitatif, une forme d'exécution de cette fixation de ski de randonnée, sur lesquels

  • la figure 1 représente la fixation en position descente;
  • la figure 2 représente la fixation en position montée.
The invention will be better understood with the aid of the description which follows, with reference to the appended schematic drawings showing, by way of nonlimiting example, an embodiment of this ski touring binding, in which
  • Figure 1 shows the attachment in the down position;
  • Figure 2 shows the attachment in the mounted position.

A la figure 1 on voit le ski 1 sur lequel est fixé du côté avant une plaque 13 comportant deux éléments plans 12 constituant une chape supportant l'axe 9. Du côté opposé à la plaque 13 on voit un dispositif 2 fixé sur le ski 1. Le dispositif 2 est destiné à maintenir à volonté l'élément allongé 8, qui peut être une plaque pleine, ou une plaque comportant des évidements, ou encore deux tiges métalliques, fixé sur le ski 1. Le dispositif 2 comprend un levier 3 ou tout autre moyen permettant de commander le maintien ou la libération de l'élément allongé 8.In Figure 1 we see the ski 1 on which is fixed on the front side a plate 13 having two planar elements 12 constituting a yoke supporting the axis 9. On the side opposite to the plate 13 we see a device 2 fixed to the ski 1 The device 2 is intended to hold the elongated element 8 at will, which can be a solid plate, or a plate comprising recesses, or even two metal rods, fixed on the ski 1. The device 2 comprises a lever 3 or any other means enabling the maintenance or release of the elongated element 8 to be controlled.

L'élément allongé 8 comprend à sa partie arrière une talonnière 6 liée à une plaque de talon 5 de manière à pouvoir maintenir l'arrière d'une chaussure 7 par sa semelle 4 sur l'élément allongé 8. La plaque de talon 5 comporte des moyens permettant de la fixer en différents endroits sur l'élément 8 de manière à pouvoir ajuster sa position à la longueur de la chaussure. A sa partie avant l'élément allongé 8 comprend une butée avant constituée par une mâchoire 10 et un dispositif de sécurité 11 de manière à pouvoir maintenir une chaussure 7. L'élément de sécurité peut être de tout type de butée avant de fixation de ski connu de l'homme de métier.The elongate element 8 comprises at its rear part a heel piece 6 linked to a heel plate 5 so as to be able to hold the rear of a shoe 7 by its sole 4 on the elongate element 8. The heel plate 5 comprises means for fixing it in different places on the element 8 so as to be able to adjust its position to the length of the shoe. At its front part the elongated element 8 comprises a front stop constituted by a jaw 10 and a safety device 11 so as to be able to hold a boot 7. The safety element can be of any type of stop before ski binding known to those skilled in the art.

Comme on peut le voir l'axe de rotation se trouve bien au-dessus du plan de l'élément allongé 8 à une hauteur H. On s'efforcera à réaliser une fixation où la hauteur H sera telle que l'axe 9 se trouve le plus proche possible de la partie supérieure de l'empeigne 7 de la chaussure lorsque cette dernière est disposée sur la fixation.As we can see the axis of rotation is well above the plane of the elongated element 8 at a height H. We will endeavor to achieve a fixing where the height H will be such that the axis 9 is as close as possible to the upper part of the upper 7 of the shoe when the latter is disposed on the binding.

La figure 2 représente schématiquement la même fixation que celle représentée à la figure 1 mais dans la position où le talon de la chaussure 7 est écarté du ski 1. Comme on peut le constater le mouvement de l'élément allongé 8 représenté par la ligne trait-point 14 développe une force qui à tendance à chasser le ski 1 vers l'avant c'est-à-dire vers la gauche sur la figure 2.Figure 2 shows schematically the same binding as that shown in Figure 1 but in the position where the heel of the boot 7 is separated from the ski 1. As can be seen the movement of the elongated element 8 represented by the line -point 14 develops a force which tends to drive the ski 1 forward that is to say to the left in Figure 2.

Par la réalisation de la fixation de randonnée selon l'invention on a fourni une fixation qui diminue l'effort et augmente le rendement à l'avancement.By producing the trekking binding according to the invention, a binding has been provided which reduces the effort and increases the yield on advancement.

Comme il va de soit, l'invention ne se limite pas à la seule forme d'exécution de cette fixation de ski qui a été ci-devant exposée à titre d'exemple, mais enliasse toutes les variantes d'exécution, notamment en ce qui a trait à l'élément allongé 8, à la butée avant et au dispositif 2 destiné à permettre le maintien ou la libération de l'élément 8 sur le ski.It goes without saying that the invention is not limited to the sole embodiment of this ski binding which has been explained above by way of example, but combines all the variant embodiments, in particular in that which relates to the elongated element 8, the front stop and the device 2 intended to allow the maintenance or the release of the element 8 on the ski.
