Abstract

The fastening consists of a clamp with two jaws (3, 4) in the form of first order levers which open outwards and close to engage with the edge of the boot sole. The jaws have lateral stops which press against the upper of the boot toe, and the clamp has additional front stops (12) to engage with the end of the boot sole, made in the form of rollers with vertical axes of rotation. The lateral stops are in the form of low-friction components and can also be rollers.

Description

La présente invention concerne une fixation de sécurité d'une chaussure de ski à semelle débordante sur un ski, comprenant une mâchoire présentant deux bras indépendants de manière à s'ouvrir à l'opposé l'un de l'autre lors du chaussage et aptes à retenir verticalement la chaussure par sa semelle débordante, la mâchoire pouvant pivoter latéralement sous l'action de la chaussure contre l'action d'un ressort de rappel.The present invention relates to a safety binding a ski boot with an overflowing sole on a ski, comprising a jaw with two arms independent so as to open opposite one of the other during the fitting and able to retain vertically the shoe by its overflowing sole, the jaw can pivot laterally under the action of the shoe against the action of a return spring.

L'invention concerne particulièrement une fixation destinée à fixer l'extrémité avant de la chaussure, mais elle pourrait également s'appliquer à la fixation de l'extrémité arrière de la chaussure.The invention particularly relates to a fixing intended to fix the front end of the shoe, but it could also apply to fixation from the back end of the shoe.

D'une manière générale on peut distinguer trois types de fixation avant.Generally we can distinguish three types front fixing.

Dans les fixations du premier type, la mâchoire retient la chaussure latéralement et verticalement par la partie débordante de la semelle par deux bras indépendants de manière à s'ouvrir à l'opposé l'un de l'autre lors du chaussage. A titre d'exemple, on peut citer les fixations décrites dans la demande de brevet DE 2 756 895 et dans le brevet EP 0 295 372. Compte tenu de la forme de l'extrémité avant de la semelle, la course élastique de la chaussure, c'est-à-dire le déplacement latéral de la chaussure avant que celle-ci échappe à la fixation, est relativement courte, ce qui peut avoir pour conséquence un échappement intempestif de la chaussure entraínant une chute du skieur. Un autre inconvénient de ce type de fixation réside dans l'accumulation de neige sous les mâchoires, entre celles-ci et le ski ou la plaque sur laquelle vient glisser latéralement la semelle de la chaussure.In fasteners of the first type, the jaw retains the shoe laterally and vertically by the protruding part of the sole by two arms independent so as to open opposite one of the other when putting on. For example, we can quote the fasteners described in the patent application DE 2,756,895 and in patent EP 0 295 372. Account given the shape of the front end of the sole, the elastic race of the shoe, i.e. the lateral movement of the shoe before it escapes fixation, is relatively short, which may result in untimely exhaust of the shoe causing a fall of the skier. A another disadvantage of this type of attachment is the accumulation of snow under the jaws, between these and the ski or the plate on which comes slide the sole of the shoe sideways.

Le brevet EP 0 241 360 illustre une fixation du deuxième type. Dans celle-ci, la chaussure est retenue latéralement par sa tige et verticalement par la face supérieure de la semelle débordante les bras prennent donc appui en des points plus éloignés de l'axe de la chaussure et sur une surface beaucoup plus arrondie que l'extrémité de la semelle, de telle sorte que l'on obtient une grande course élastique. En outre, les bras de la mâchoire sont à une hauteur sensiblement plus élevée au-dessus de la plaque d'appui de la semelle et du ski, de telle sorte que la neige n'est pas retenue sous la mâchoire. Un inconvénient d'une telle fixation est toutefois la pression élevée de la mâchoire sur la tige, c'est-à-dire la coque de la chaussure, qui ne présente pas la rigidité et la résistance de la semelle et qui peut donc se déformer sous la pression de la mâchoire en modifiant totalement les conditions de déclenchement de la fixation. Un autre inconvénient réside dans le fait que lors d'une chute avant la totalité de la poussée vers l'avant s'exerce sur les bras, ce qui peut provoquer un déclenchement de la fixation avant, alors que c'est le rôle de la talonnière de déclencher.Patent EP 0 241 360 illustrates a fixing of the second type. In it, the shoe is retained laterally by its rod and vertically by the face upper of the overflowing sole the arms take so support at points further from the axis of the shoe and on a much more rounded surface than the end of the sole, so that obtains a large elastic stroke. In addition, the arms of the jaw are at a significantly higher height raised above the sole support plate and skiing so that snow is not retained under the jaw. A disadvantage of such a fixation however is the high pressure of the jaw on the upper, that is to say the shell of the shoe, which does not not stiffness and resistance of the sole and which can therefore be deformed under the pressure of the jaw by totally changing the conditions of release of fixation. Another downside lies in the fact that during a fall before the the entire forward thrust is exerted on the arm, which can trigger the front fixing, while this is the role of the heel to trigger.

La fixation du troisième type, décrite dans le brevet FR 2 464 727, comprend deux bras prenant appui sur la tige de la chaussure et une butée frontale contre laquelle vient s'appuyer la semelle. Les bras sont liés rigidement au corps pivotant de la fixation et ils ne peuvent pas s'écarter l'un de l'autre. Afin d'assurer un appui frontal et sur tige l'écartement des bras est réglable au moyen de vis de butée. Un tel réglage est délicat. Si les bras sont trop pincés, la tige est écrasée lorsque la semelle vient en butée. La déformation de la tige et l'augmentation de la surface de contact des bras avec la tige, qui en résultent, peuvent gêner le déclenchement de la fixation. Si les bras sont trop écartés, ce qui peut résulter d'un déréglage, un jeu apparaít, qui se traduit par un mauvais guidage du ski et donc un sentiment d'insécurité.The fixation of the third type, described in the patent FR 2 464 727, includes two arms bearing on the shoe upper and a front stop against which rests on the sole. The arms are tied rigidly to the pivoting body of the binding and they don't cannot deviate from each other. To assure a front and rod support the arm spacing is adjustable by means of stop screws. Such a setting is delicate. If the arms are too pinched, the rod is crushed when the sole stops. The stem deformation and increased surface area contact of the arms with the rod, which result therefrom, may interfere with the release of the binding. If the arms are too far apart, which can result from adjustment, a game appears, which results in a poor ski guidance and therefore a feeling insecurity.

La présente invention a pour but de réaliser une fixation de ski présentant l'ensemble des avantages des fixations connues, mais ne nécessitant pas de réglage manuel des bras de la mâchoire.The object of the present invention is to provide a ski binding with all the advantages of known fasteners, but not requiring adjustment manual of the jaw arms.

Ce but est atteint par la fixation de la revendication 1, dont le préambule est connu de EP0295372 et EP0320854.This object is achieved by setting claim 1, whose preamble is known from EP0295372 and EP0320854.

L'indépendance des bras de la mâchoire autorise un écartement de ceux-ci, contre l'action du ressort de rappel de la fixation, de telle sorte que l'extrémité frontale de la semelle peut venir en butée contre les moyens de butée frontale. La plus grande partie de l'effort axial exercé par l'autre élément de fixation sur la chaussure est donc supportée par les moyens de butée frontale. Par ailleurs, la mâchoire s'ajuste d'elle-même à la largeur de la tige de la chaussure. Cette adaptation automatique engendre une coopération efficace entre fixation et chaussure permettant d'obtenir une fixation performante.The independence of the arms of the jaw allows a spacing of these, against the action of the spring of fixing reminder, so that the end front of the sole can abut against frontal stop means. Most of the axial force exerted by the other fastening element on the shoe is therefore supported by the means of front stop. Furthermore, the jaw adjusts of itself to the width of the upper of the shoe. This automatic adaptation generates cooperation effective between binding and shoe allowing to obtain an efficient fixation.

En outre, l'espace libre sous les bras de la mâchoire, de chaque côté des moyens de butée frontale, permet à la neige de s'évacuer.In addition, the free space under the arms of the jaw, on each side of the front stop means, allows snow to drain.

Les moyens de butée frontale sont de préférence constitués de galets à axe vertical.The front stop means are preferably made up of rollers with vertical axis.

Ces galets peuvent être montés sur la mâchoire, de préférence autour d'axes distincts des axes de pivotement des bras de la mâchoire.These rollers can be mounted on the jaw, preferably around axes separate from the axes of pivoting of the jaw arms.

Les parties des bras de la mâchoire venant en appui contre la tige présentent avantageusement un faible coefficient de frottement ou sont munis de galets.The parts of the arms of the jaw bearing against the rod advantageously have a low coefficient of friction or are fitted with rollers.

Le dessin annexé représente, à titre d'exemple, deux modes d'exécution de l'invention.The accompanying drawing shows, by way of example, two modes of carrying out the invention.

La Figure 1 est une vue en perspective de dessus de la fixation, en l'occurrence une butée avant selon un premier mode d'exécution.Figure 1 is a perspective view from above of the fixing, in this case a front stop according to a first mode of execution.

La Figure 2 est une vue en perspective de dessous, chaussure représentée en traits mixtes, du même mode d'exécution. Figure 2 is a perspective view from below, shoe shown in mixed lines, of the same mode execution.

La Figure 3 est une vue de dessous de la fixation, sans le corps de celle-ci et sans la plaque d'appui de la semelle, la chaussure étant engagée dans la butée sous la poussée d'une fixation arrière ou talonnière.Figure 3 is a bottom view of the binding, without the body of it and without the backing plate of the sole, the shoe being engaged in the stop under the push of a rear or heel binding.

La figure 4 est une vue en coupe axiale, selon IV-IV de la figure 5, d'une second mode d'exécutionFigure 4 is an axial sectional view, along line IV-IV of Figure 5, of a second embodiment

La figure 5 est une vue en plan, partiellement en coupe selon V-V de la figure 4, de ce second mode d'exécution.Figure 5 is a plan view, partially in section according to V-V of FIG. 4, of this second mode execution.

La figure 6 est une vue de dessus de la mâchoire droite d'une variante d'exécution du premier mode d'exécution.Figure 6 is a top view of the right jaw of an alternative embodiment of the first embodiment.

La figure 7 est une vue en coupe selon VII-VII de la figure 6.Figure 7 is a sectional view along VII-VII of the figure 6.

La fixation représentée aux figures 1 à 3 comprend une embase 1 sur laquelle est montée un corps de fixation 2 portant une mâchoire constituée de deux bras 3 et 4 montés basculant, de manière indépendante, autour de deux axes verticaux situés de part et d'autre de l'axe longitudinal de la fixation, comme décrit et représenté dans le brevet EP 0 295 372. Ces bras 3 et 4 constituent des leviers du premier genre dont les extrémités intérieures viennent agir sur un tirant 5 dont l'extrémité 5a s'appuie sur une douille 6 contre le fond de laquelle s'appuie un ressort 7 travaillant en compression entre le fond de la douille et une face d'appui fixe 8. Cette construction est semblable à la construction décrite dans le brevet EP 0 295 372.The binding shown in Figures 1 to 3 includes a base 1 on which a fixing body 2 is mounted carrying a jaw made up of two arms 3 and 4 mounted tilting, independently, around two vertical axes located on either side of the axis longitudinal of the binding, as described and shown in patent EP 0 295 372. These arms 3 and 4 constitute levers of the first kind whose inner ends act on a tie rod 5 whose end 5a rests on a socket 6 against the bottom of which is supported a working spring 7 in compression between the bottom of the socket and a face 8. This construction is similar to the construction described in patent EP 0 295 372.

Les mâchoires 3 et 4 sont situées à une hauteur telle, relativement à l'embase 1, que lorsque la chaussure 9 est engagée dans la butée, les bras 3 et 4 sont situés au-dessus de la semelle normalisée 10 de la chaussure et viennent prendre appui sur la tige 11 de la chaussure. Dans leur zone d'appui les bras 3 et 4 sont avantageusement munis de pièces rapportées à faible coefficient de frottement.The jaws 3 and 4 are located at such a height, relative to the base 1, that when the shoe 9 is engaged in the stop, arms 3 and 4 are located above the standard sole 10 of the shoe and come to rest on the rod 11 of the shoe. In their support zone arms 3 and 4 are advantageously provided with inserts with low coefficient of friction.

Les bras 3 et 4 portent respectivement un galet 12 et 13 monté autour d'un axe vertical 14, respectivement 15, distinct de l'axe de pivotement du bras correspondant et situé entre cet axe de pivotement et la partie du bras prenant appui contre la tige de la chaussure. Les galets 12 et 13 constituent des moyens de butée frontale pour la partie frontale 10a de la semelle 10 qui déborde en avant de la tige 11.The arms 3 and 4 respectively carry a roller 12 and 13 mounted around a vertical axis 14, respectively 15, distinct from the pivot axis of the arm corresponding and located between this pivot axis and the part of the arm resting against the rod of the shoe. The rollers 12 and 13 constitute means front stop for the front part 10a of the sole 10 which projects in front of the upper 11.

Lorsque la chaussure est fixée entre l'élément de fixation avant représenté et un élément de fixation arrière, la semelle 10 vient s'appuyer sur une surface d'appui 16 fixée sur l'embase 1 et sa partie frontale 10a vient en butée contre les galets 12 et 13, en écartant légèrement les bras 3 et 4 qui s'ajustent ainsi automatiquement à la largeur de la tige 11. Compte tenu de la position des axes 14 et 15 des galets 12 et 13, la poussée axiale sur ces galets n'a que peu d'effet sur le tirant 5. Dans tous les cas les galets 12 et 13 supportent la plus grande partie de l'effort axial exercé sur la chaussure. La zone d'appui des bras 3 et 4 sur la tige 11 de la chaussure peut varier quelque peu en fonction de l'effort axial et des dimensions et de la forme de la tige, mais ceci est pratiquement sans influence sur la force de rappel des bras.When the shoe is fixed between the element of front fixing shown and a fixing element rear, sole 10 comes to rest on a surface support 16 fixed on the base 1 and its front part 10a abuts against the rollers 12 and 13, in slightly spreading arms 3 and 4 which adjust thus automatically to the width of the rod 11. Taking into account the position of axes 14 and 15 of the rollers 12 and 13, the axial thrust on these rollers has little effect on the tie rod 5. In all cases the rollers 12 and 13 support most of the effort axial exerted on the shoe. The arm support area 3 and 4 on the upper 11 of the shoe may vary somewhat depending on the axial force and dimensions and shape of the rod but this is practically without influence on the restoring force of arms.

Lorsqu'une torsion suffisante est exercée sur la chaussure 9, celle-ci écarte l'un des bras 3 ou 4. Compte tenu de la longueur relativement importante de ces bras et de l'enveloppement correspondant de la tige par ceux-ci, la course élastique des bras est relativement grande avant que la chaussure s'échappe de la fixation.When sufficient torsion is exerted on the shoe 9, this separates one of the arms 3 or 4. Given the relatively large length of these arms and the corresponding wrapping of the rod by these, the elastic stroke of the arms is relatively large before the shoe escapes from fixation.

Il ressort en outre clairement des figures 1 et 2 que la neige ne peut pas s'accumuler dans la mâchoire, sous les bras 3 et 4 étant donné que l'espace est libre sous ces bras, permettant à la neige de s'évacuer.It is also clear from Figures 1 and 2 that snow cannot accumulate in the jaw, under arms 3 and 4 since the space is free under these arms, allowing the snow to escape.

Chacun des bras 3 et 4 pourrait être pourvu d'un ou de plusieurs galets par lesquels les bras prendraient appui sur la tige de la chaussure.Each of arms 3 and 4 could be provided with one or several rollers by which the arms would take support on the upper of the shoe.

Le second mode d'exécution, représenté aux figures 4 et 5, diffère du premier mode d'exécution en ce que les moyens de butée frontale sont constitués d'une butée 17 solidaire de l'embase 1. Dans le cas particulier cette butée 17 est venue d'une pièce avec l'embase. Sur la figure 5 on voit la nervure verticale 18 sur laquelle pivote le bras 3. The second embodiment, shown in Figures 4 and 5, differs from the first embodiment in that the front stop means consist of a stop 17 secured to the base 1. In the particular case, this stop 17 came in one piece with the base. On the Figure 5 we see the vertical rib 18 on which swivels the arm 3.

La butée 17 pourrait également être munie de galets.The stop 17 could also be provided with rollers.

Le montage des moyens de butée latérale et frontale sur les bras de la mâchoire peut être simplifié et rationalisé par la construction représentée aux figures 6 et 7.The mounting of the lateral and frontal stop means on the arms of the jaw can be simplified and rationalized by the construction shown in the figures 6 and 7.

La mâchoire 3', vue de dessous à la figure 6, comme la mâchoire 3 de la figure 3, est munie d'une pièce rapportée 30 à faible coefficient de frottement destinée à venir s'appuyer sur la tige de la chaussure, comme décrit précédemment. Cette pièce 30 présente un trou 31, ainsi qu'une fente 32 perpendiculaire à l'axe du trou 31. La pièce 30 est montée dans un logement 20 de la mâchoire 3' présentant une nervure 21 s'engageant dans la fente 32.The jaw 3 ', seen from below in FIG. 6, like the jaw 3 of Figure 3, is provided with a part reported 30 with low coefficient of friction intended to come to rest on the upper of the shoe, as previously described. This part 30 presents a hole 31, as well as a slot 32 perpendicular to the axis of the hole 31. The part 30 is mounted in a housing 20 jaw 3 'having a rib 21 engaging in slot 32.

La mâchoire 3' est en outre munie d'un galet 12 situé en dessous de la pièce 30 et destiné à servir d'appui à la partie frontale de la semelle de la chaussure. Ce galet 12 est monté dans un logement 22 de la mâchoire 3'.The jaw 3 'is further provided with a roller 12 located below part 30 and intended to serve as support for the front part of the sole of the shoe. This roller 12 is mounted in a housing 22 of the jaw 3 '.

Le galet 12 et la pièce d'appui 30 sont retenus dans la mâchoire 3' au moyen d'une goupille commune 23 chassée dans un trou 24 traversant les logements 20 et 22 de la mâchoire. Dans sa moitié inférieure, la goupille 23 présente une partie de section réduite 23a permettant au galet 12 de tourner avec jeu autour de la goupille 23. The roller 12 and the support piece 30 are retained in the 3 'jaw by means of a common pin 23 driven out in a hole 24 passing through the housings 20 and 22 of the jaw. In its lower half, the pin 23 has a reduced section portion 23a allowing the roller 12 to rotate with play around the pin 23.
