Abstract
Description
L'invention concerne un élément de retenue d'une chaussure sur un ski.The invention relates to a shoe retention element on a ski.
Plus exactement, l'invention concerne un élément de retenue avant qui est prévu pour retenir de façon libérable l'avant d'une chaussure. De façon connue, un tel élément présente une mâchoire qui est mobile contre la force de rappel que lui oppose un moyen de rappel élastique, par exemple un ressort.More precisely, the invention relates to a front retaining element which is designed to releasably retain the front of a shoe. In known manner, a such element has a jaw which is movable against the restoring force that it opposes an elastic return means, for example a spring.
Parmi les éléments de retenue connus, l'invention concerne ceux dont le déclenchement est asymétrique, c'est-à-dire qui libère la chaussure plus facilement d'un côté que de l'autre. On sait en effet que la jambe d'un skieur est capable d'endurer des torsions plus élevées pour une rotation de l'avant du pied vers l'extérieur que pour une rotation vers l'intérieur, c'est-à-dire vers l'autre pied. Il est donc apparu intéressant de réaliser des éléments de retenue qui prennent en compte cette dissymétrie.Among the known retaining elements, the invention relates to those whose trigger is asymmetrical, that is to say that releases the shoe more easily on one side than on the other. We know that a skier's leg is capable endure higher twists for rotation from the forefoot to the outside only for an inward rotation, that is to say towards the other foot. It is so it appeared interesting to make retaining elements which take into account account for this asymmetry.
Les demandes de brevet publiées sous les numéros FR 1 503 849, FR 1 503 847 décrivent de tels éléments qui libèrent la chaussure de façon asymétrique.Patent applications published under the numbers FR 1 503 849, FR 1 503 847 describe such elements which release the shoe in a way asymmetric.
Ces constructions présentent toutefois l'inconvénient de retenir la chaussure en tout ou rien. Ces éléments de retenue ne présentent pas de course élastique, c'est-à-dire que pour de faibles sollicitations, ils ne permettent pas à la chaussure de se décaler latéralement en assurant ensuite son recentrage sur le ski.However, these constructions have the disadvantage of retaining the shoe in all or nothing. These retaining elements do not have an elastic stroke, that is to say that for low loads, they do not allow the shoe to shift laterally then ensuring its refocusing on the ski.
Parmi les constructions actuelles qui présentent une course élastique, on
connaít d'après la demande de brevet français publiée sous le numéro FR 2 517
214, ou la demande de brevet suisse publiée sous le numéro CH 664 699 une
construction comprenant une mâchoire et un corps monobloc montés de façon
pivotante sur un pivot central selon deux lignes d'appui convergentes. Une telle
construction donne de bons résultats pour la retenue et la libération d'une
chaussure. En outre, elle se prête bien à l'aménagement de mécanismes
d'allégement qui permettent de diminuer la force que la chaussure doit vaincre
pour être libérée en cas de chute complexe. L'un de ces mécanismes est par
exemple décrit dans la demande de brevet allemand publiée sous le numéro
DE 33 43 545. Toutefois, son fonctionnement est symétrique.Among the current constructions which have an elastic stroke,
knows from the French patent application published under the
Un but de l'invention est d'améliorer ce type d'élément de retenue en rendant son fonctionnement asymétrique par des modifications simples de sa construction.An object of the invention is to improve this type of retaining element by making its asymmetrical functioning by simple modifications of its construction.
L'élément de retenue selon l'invention comprend un pivot central, une mâchoire et un corps monobloc montés de façon pivotante autour du pivot et s'appuyant sur au moins une ligne de pivotement, un ressort de rappel logé dans le corps et s'appuyant contre le pivot pour rappeler le corps dans une position centrée. Il est caractérisé par le fait qu'un élément de liaison asymétrique est placé à la liaison entre le corps, le pivot et le ressort. The retaining element according to the invention comprises a central pivot, a jaw and a one-piece body pivotally mounted around the pivot and supported by at least one pivot line, a return spring housed in the body and leaning against the pivot to recall the body in a position centered. It is characterized by the fact that an asymmetrical connecting element is placed at the connection between the body, the pivot and the spring.

Les figures 1 et 2 représentent un élément de retenue avant qui est connu
pour l'essentiel de la demande de brevet français publiée sous le numéro FR 2 537
442.Figures 1 and 2 show a known front retaining element
for the main part of the French patent application published under the
Cet élément comprend un socle 1 prévu pour être solidarisé au ski, par tout
moyen approprié, par exemple par des vis. Le socle se prolonge vers l'arrière par
une plaque d'appui 2 destinée à supporter l'extrémité d'une semelle de chaussure.This element comprises a base 1 intended to be secured to the ski, by any
suitable means, for example by screws. The base is extended towards the rear by
a
Le socle 1 est surmonté d'un pivot 3. La base du pivot présente vers l'arrière,
c'est-à-dire du côté de la chaussure, deux zones d'appui 4 et 5 conformées comme
des rainures verticales qui sont situées de part et d'autre d'un plan longitudinal et
vertical médian défini par le ski. Une vis 6 est vissée au sommet du pivot. La vis est
verticale et elle est située dans le plan médian mentionné précédemment. La vis
présente au niveau de sa tête une gorge annulaire 8 dont la hauteur par rapport à
la face inférieure du socle varie en fonction du vissage de la vis dans son
logement.The base 1 is surmounted by a
Vers l'avant, le pivot présente une face d'appui approximativement plane 9
qui s'étend transversalement au plan médian, sur sensiblement toute la hauteur du
pivot, et sur une largeur un peu supérieure à la distance séparant les deux zones
d'appui.Forward, the pivot has an approximately flat bearing
L'élément de retenue comprend par ailleurs une mâchoire 10 de retenue de
la chaussure. La mâchoire se prolonge vers l'avant par un corps 11, et forme avec
le corps un ensemble monobloc.The retaining element also comprises a
Le corps 11 est suspendu par sa partie supérieure à la tête de vis 6, au niveau
de la gorge annulaire 8.The
Vers le bas, le corps présente deux zones d'appui 14 et 15, conformées en
nervures verticales. Ces zones d'appui en relief sont prévues pour coopérer avec
les zones en creux 4 et 5 du pivot.Towards the bottom, the body has two
Un ressort 13 est logé dans un logement 16 du corps. Le logement est obturé
sur l'avant par un bouchon fileté 17, et vers l'arrière, le logement débouche en
regard de la face d'appui 9. Le ressort est en appui contre cette face par
l'intermédiaire d'un piston 18 emboíté dans une contre-pièce d'appui 19.A
Le ressort 15 rappelle le corps et la mâchoire dans une position alignée sur le
plan vertical médian. Au cours de la pratique du ski, la mâchoire et le corps
peuvent pivoter latéralement autour de l'une ou l'autre des deux lignes d'appui
convergentes formées par la tête de vis, et les deux zones d'appui couplées 4 et 14
ou 5 et 15.The
La force que la chaussure doit vaincre pour entraíner la mâchoire en rotation
est déterminée par le vissage du bouchon 17. La hauteur du corps et de la
mâchoire est réglable par la vis 6.The force that the shoe must overcome to cause the jaw to rotate
is determined by screwing the
La construction qui vient d'être décrite est connue, et des variantes de construction sont possibles.The construction which has just been described is known, and variants of construction are possible.
La figure 4 illustre un premier mode de mise en oeuvre de l'invention.FIG. 4 illustrates a first embodiment of the invention.
Selon ce mode de mise en oeuvre, l'un des couples de zones d'appui entre le corps et le pivot est plus proche du plan vertical médian passant par la vis que l'autre couple de zones d'appui.According to this embodiment, one of the pairs of support zones between the body and the pivot is closer to the median vertical plane passing through the screw than the other pair of support zones.
Ainsi, dans la figure 4, le plan vertical médian est schématisé en 20, et les
zones d'appui 23 et 25, respectivement du pivot et du corps sont plus proches du
plan 20 et de la vis 21 que l'autre couple de zones d'appui 22, 24.Thus, in Figure 4, the median vertical plane is shown schematically at 20, and the
De cette façon, la rotation du corps autour des lignes d'appui passant par le
couple de zones 23 et 25 demande un effort moins important de la part de la
chaussure que la rotation autour de l'autre ligne d'appui. La position centrée du
corps et de la mâchoire demeure inchangée.In this way, the rotation of the body around the support lines passing through the
pair of
La figure 5 représente un autre mode de mise en oeuvre de l'invention. Selon
ce mode de mise en oeuvre, la face d'appui 29 du pivot 28 est chanfreinée sur un
bord repéré en 30. De préférence, le chanfrein 30 ne traverse pas le plan médian,
et la contre-pièce d'appui vient en appui contre le chanfrein seulement après un
décalage angulaire du corps par rapport à sa position centrée, afin que la position
centrée demeure une position d'équilibre stable de la mâchoire. Dans la position
centrée, la contre-pièce 19 du corps repose en effet sur la portion médiane de la
face 29 qui est plane et perpendiculaire au plan longitudinal médian.FIG. 5 represents another embodiment of the invention. according to
this embodiment, the bearing
De cette façon, le sens de rotation du corps où la contre-pièce d'appui vient au contact du chanfrein demande moins d'effort de la part de la chaussure que l'autre sens de rotation.In this way, the direction of rotation of the body where the counter piece comes from in contact with the chamfer requires less effort from the shoe than the other direction of rotation.
La figure 6 illustre une variante de réalisation. Selon cette variante, la face
d'appui 31 du pivot 32, avec son chanfrein 33 est portée par une languette 34
rapportée à la face avant du pivot. Par exemple, comme le montrent les figures 6 et
7, la languette est engagée depuis le dessous au travers d'une ouverture se
trouvant dans le socle 35, au pied du pivot 32. Tout moyen approprié, par exemple
des rainures verticales complémentaires peuvent être utilisées pour assurer un
placage et un maintien de la languette contre la face arrière du pivot.Figure 6 illustrates an alternative embodiment. According to this variant, the
Cette variante permet avantageusement de pouvoir réaliser deux éléments de
retenue asymétriques d'une paire d'éléments au moyen d'un nombre important de
pièces identiques, et un nombre réduit de pièces asymétriques, en l'occurrence
deux languettes 34 présentant des chanfreins opposés. Avantageusement, ces
languettes qui définissent la polarisation des éléments peuvent être rapportées en
fin de processus d'assemblage des éléments de retenue.This variant advantageously makes it possible to be able to produce two elements of
asymmetrical restraint of a pair of elements by means of a large number of
identical parts, and a reduced number of asymmetrical parts, in this case
two
Les figures 8 et 9 sont relatives à un autre mode de mise en oeuvre de
l'invention se rapportant à la contre-pièce d'appui 36. Cette contre-pièce est prévue
pour être rapportée à l'extrémité du piston. Elle présente de façon usuelle deux
chanfreins latéraux 37 et 38, et une surface centrale 39 de forme globale
triangulaire avec la pointe orientée vers le bas. Selon la présente variante, l'une
des arêtes délimitant l'un des chanfreins, en l'occurrence l'arête 40 du chanfrein
37, et la surface centrale 39, est plus proche du plan vertical médian de la contre-pièce
que l'autre arête.Figures 8 and 9 relate to another embodiment of
the invention relating to the supporting
Les figures 10 et 11 illustrent un autre mode de mise en oeuvre de l'invention.
Selon ce mode de mise en oeuvre, le ressort 45 est en liaison avec le pivot 46 par
l'intermédiaire d'un basculeur 47 articulé autour d'un axe supérieur 44 porté par le
corps. Le basculeur porte une clavette transversale 48 en saillie qui peut osciller
dans un logement de forme arrondie. La clavette 48 est en appui contre la face
avant 49 du pivot 46. Comme cela est visible dans la figure 11, la face avant 49 du
pivot est légèrement en relief avec deux arêtes d'appui 50 et 51 contre lesquelles
la clavette porte. L'oscillation de la clavette permet d'assurer un bon appui contre
l'une ou l'autre des arêtes d'appui au cours de la rotation du corps.Figures 10 and 11 illustrate another embodiment of the invention.
According to this embodiment, the
Selon la présente variante, la face d'appui de la clavette présente d'un côté
de son plan vertical médian un dégagement 53 dont l'épaisseur de dégagement
augmente du bord de la clavette vers la partie centrale. La position et les
dimensions du dégagement 53 sont prévues pour que l'arête en regard 50 soit en
dehors du dégagement lorsque le corps et la mâchoire sont en position centrée, et
que cette arête ne parcoure le dégagement 50 qu'à la suite d'un écart du corps par
rapport à sa position centrée.According to this variant, the bearing face of the key has on one side
from its vertical median plane a
Le ressort oppose une résistance moindre, c'est-à-dire qui augmente moins
vite, à la rotation du corps pour un sens de rotation où l'arête 50 vient en appui
contre l'arête 50.The spring offers less resistance, that is to say that increases less
quickly, to the rotation of the body for a direction of rotation where the
Comme dans le cas précédent, il serait possible selon une autre variante de
disposer les arêtes 50 et 51 de façon asymétrique à la face avant du pivot, par
exemple en ayant recours à une pièce rapportée comme dans le cas des figures 6
et 7.As in the previous case, it would be possible according to another variant of
arrange the
Les figures 12 et 13 illustrent une autre variante. Cette variante met en oeuvre
un pivot 55, du même type que le pivot précédent, avec des arêtes d'appui 56 et
57. Le ressort 58 est ici en appui contre les arêtes 56 et 57 par l'intermédiaire d'un
piston 60 qui est monté coulissant dans le bouchon fileté 61.Figures 12 and 13 illustrate another variant. This variant implements
a
Comme dans le cas précédent, la face d'appui 62 du piston 60 présente un
dégagement 63 qui est prévu pour servir d'appui à l'arête 56 pour une rotation du
corps dans un sens déterminé. Pour une telle rotation, la force de rappel du ressort
58 augmente moins vite pour une rotation dans ce sens.As in the previous case, the bearing
Avantageusement, le bouchon 61, le ressort 58 et le piston 60 forment une
cartouche qui est rapportée au reste de l'élément de retenue en tant que sous-ensemble.
Dans ce cas, le piston présente latéralement un repère de guidage et de
détrompage en saillie qui est prévu pour coopérer avec un organe complémentaire
du corps. Ce repère est illustré en 65 dans les figures. Il est prévu pour coopérer
avec une rainure située à la paroi du logement du corps. Il permet à la fois de caler
angulairement le piston pour que l'engagement soit correctement orienté, et de
guider le piston au cours de la compression du ressort.Advantageously, the
Selon une variante, le logement du corps est équipé de deux rainures
disposées de façon à orienter le piston de deux façons différentes, selon que le
dégagement 63 est prévu pour coopérer avec l'arête 56 ou l'autre arête 57.
Comme dans le cas décrit relativement aux figures 6 et 7, le nombre de pièces
asymétriques d'une paire d'éléments de retenue est ici très réduit.According to a variant, the housing of the body is equipped with two grooves
arranged to orient the piston in two different ways, depending on whether the
Il va de soi que pour les différents modes de réalisation décrits, l'autre élément de retenue d'une paire d'éléments asymétriques présente un élément d'asymétrie opposée à celle qui a été décrite.It goes without saying that for the various embodiments described, the other retainer of a pair of asymmetric members has an element opposite asymmetry to that which has been described.
En outre, les éléments de retenue sont équipés de tout moyen approprié de façon à rendre visible la nature de leur asymétrie, c'est-à-dire de façon à repérer un élément de retenue droit et un élément de retenue gauche d'une paire. In addition, the retaining elements are fitted with any appropriate means of in order to make visible the nature of their asymmetry, that is to say in order to identify a right retainer and left retainer of a pair.
L'invention s'applique également aux éléments de retenue, qui présentent un pivot simple formé par une tige cylindrique verticale présentant sur l'avant un méplat d'appui pour le piston.The invention also applies to retaining elements, which have a simple pivot formed by a vertical cylindrical rod having on the front a support surface for the piston.
