Description

L'invention concerne un sous-ensemble pour le rappel élastique de l'organe de retenue d'un élément de fixation alpine.The invention relates to a sub-assembly for the elastic return of the retaining member of an alpine binding element.

De façon connue, un élément de fixation alpine présente un organe de retenue d'une extrémité de la chaussure, qui est mobile contre la force de rappel élastique d'un ressort, qui, dans le cas de la présente invention, est un ressort de compression. L'organe de retenue transmet ses sollicitations au ressort par l'intermédiaire d'un moyen de' liaison, tel qu'un piston. En outre, il est nécessaire d'équiper le ressort de moyens permettant de régler sa compression initiale, c'est-à-dire sa précontrainte de rappel initiale, ainsi que d'autres moyens pour visualiser la compression initiale du ressort, correspondant à la dureté de réglage qui est donnée à l'élément de fixation.In known manner, an alpine binding element has a member for retaining one end of the boot, which is movable against the elastic restoring force of a spring, which, in the case of the present invention, is a spring compression. The retaining member transmits its stresses to the spring by means of a connection means, such as a piston. In addition, it is necessary to equip the spring with means making it possible to adjust its initial compression, that is to say its initial return preload, as well as other means for viewing the initial compression of the spring, corresponding to the adjustment hardness which is given to the fixing element.

Il existe des éléments de fixation pour lesquels le ressort est un ressort de compression, dont la compression initiale est réalisée à l'aide d'une vis qui traverse le ressort de part en part, et qui comprend, à l'extrémité opposée de sa tête, un écrou formant butée pour l'une des extrémités du ressort. Un tel dispositif est connu, par exemple, d'après la demande de brevet allemande DE 40 39 707, au nom de la demanderesse.There are fasteners for which the spring is a compression spring, the initial compression of which is carried out using a screw which passes right through the spring, and which comprises, at the opposite end of its head, a nut forming a stop for one of the ends of the spring. Such a device is known, for example, from the German patent application DE 40 39 707, in the name of the applicant.

Pour ce type de butée, il se pose le problème d'empêcher qu'un serrage excessif de la vis provoque la compression du ressort à spires jointives, ce qui empêcherait naturellement le ressort de jouer ensuite sa fonction de rappel élastique.For this type of stop, the problem arises of preventing excessive tightening of the screw causing compression of the spring with contiguous turns, which would naturally prevent the spring from then playing its elastic return function.

Un autre problème est de réaliser, de façon simple et économique, l'écrou formant butée, ainsi que le moyen de visualisation de la compression du ressort, tout en assurant une bonne résistance à l'usure de cet écrou.Another problem is to produce, simply and economically, the nut forming a stop, as well as the means for viewing the compression of the spring, while ensuring good wear resistance of this nut.

Le sous-ensemble de rappel élastique de l'organe de retenue d'un élément de fixation alpine, selon l'invention, comprend un ressort de compression, une vis de réglage traversant le ressort de part en part, un écrou formant butée d'appui pur l'une des extrémités du ressort, vissé sur l'extrémité filetée de la vis, un index de visualisation de la compression du ressort, et un organe de liaison avec l'organe de retenue, mobile parallèlement à l'axe du ressort avec les mouvements de l'organe de retenue. Il est caractérisé par le fait que la vis présente, dans sa partie centrale, un épaulement contre lequel l'écrou vient buter en position extrême de compression du ressort, et que, dans cette position, les spires du ressort sont encore espacées.The elastic return sub-assembly of the retaining member of an alpine fastening element, according to the invention, comprises a compression spring, an adjustment screw passing right through the spring, a nut forming a stopper pure support at one end of the spring, screwed onto the threaded end of the screw, an index showing the compression of the spring, and a connecting member with the retaining member, movable parallel to the axis of the spring with the movements of the retainer. It is characterized in that the screw has, in its central part, a shoulder against which the nut abuts in the extreme position of compression of the spring, and that, in this position, the turns of the spring are still spaced.

L'invention sera mieux comprise en se référant à la description ci-dessous, ainsi qu'aux dessins en annexe qui en font partie intégrante.The invention will be better understood by referring to the description below, as well as to the accompanying drawings which form an integral part thereof.

La figure 1 représente, en vue de côté, et en coupe partielle, un élément avant de fixation équipé d'un sous-ensemble de rappel élastique selon une première mise en oeuvre non limitative de l'invention.Figure 1 shows, in side view, and in partial section, a front fixing element equipped with an elastic return sub-assembly according to a first non-limiting implementation of the invention.

La figure 2 est une vue de côté, en coupe selon un plan longitudinal et vertical, du sous-ensemble de rappel élastique qui équipe l'élément de fixation de la figure 1.FIG. 2 is a side view, in section along a longitudinal and vertical plane, of the elastic return sub-assembly which equips the fixing element of FIG. 1.

La figure 3 représente le sous-ensemble de la figure 2 dans une autre position de fonctionnement.Figure 3 shows the sub-assembly of Figure 2 in another operating position.

La figure 4 illustre une variante de réalisation.Figure 4 illustrates an alternative embodiment.

La figure 5 représente, en vue de côté, et de façon éclatée, les différents éléments du dispositif représenté en figure 4.FIG. 5 represents, in side view, and in an exploded manner, the different elements of the device represented in FIG. 4.

La figure 1 représente, à titre d'illustration non limitative de l'invention, un élément de fixation 1, qui d'une façon connue, présente une embase 2 destinée à être solidarisée au ski, surmontée d'un corps 3. Le corps 3 porte un organe de retenue de la chaussure qui est représenté dans la figure 1 sous la forme d'une aile de retenue 4. De façon connue, l'aile est mobile autour d'un axe approximativement vertical, sous l'action des sollicitations de la chaussure. Le mouvement de l'aile 4 vers l'extérieur provoque la translation vers l'arrière selon une direction sensiblement horizontale et longitudinale d'un piston 5, contre la force de rappel élastique d'un ressort de compression 6 qui est logé à l'intérieur du piston 5.Figure 1 shows, by way of nonlimiting illustration of the invention, a fastening element 1, which in a known manner, has a base 2 intended to be secured to the ski, surmounted by a body 3. The body 3 carries a shoe retaining member which is represented in FIG. 1 in the form of a retaining wing 4. In a known manner, the wing is mobile around an approximately vertical axis, under the action of the stresses of the shoe. The movement of the wing 4 outwards causes the rearward translation in a substantially horizontal and longitudinal direction of a piston 5, against the elastic return force of a compression spring 6 which is housed in the inside of piston 5.

La compression initiale du ressort 6 est réglée au moyen d'une vis 7, dont la tête est accessible de l'extérieur, au niveau de l'extrémité avant de l'élément de fixation. La tête 8 prend appui contre le corps 3, traverse le piston, puis le ressort de part en part. A l'extrémité opposée de la tête 8, la vis 7 présente une partie filetée 9 sur laquelle est engagée un écrou 10 formant butée, contre laquelle l'extrémité arrière du ressort prend appui. Des moyens empêchent par ailleurs que l'écrou 10 suive la rotation de la vis lors d'un mouvement de réglage. Ces moyens seront décrits ultérieurement.The initial compression of the spring 6 is adjusted by means of a screw 7, the head of which is accessible from the outside, at the front end of the fixing element. The head 8 bears against the body 3, crosses the piston, then the spring right through. At the opposite end of the head 8, the screw 7 has a threaded portion 9 on which is engaged a nut 10 forming a stop, against which the rear end of the spring bears. Means also prevent the nut 10 from following the rotation of the screw during an adjustment movement. These means will be described later.

La rotation de la vis 8 provoque la translation de l'écrou 10 le long de l'axe 11 de la vis, d'où il résulte une compression ou une décompression du ressort 6.The rotation of the screw 8 causes the translation of the nut 10 along the axis 11 of the screw, from which it results in compression or decompression of the spring 6.

Un index 12 se déplace par ailleurs avec l'écrou 10. Cet index est visible de l'extérieur au travers d'une plaque transparente 13 qui équipe le capot supérieur du corps 3.An index 12 also moves with the nut 10. This index is visible from the outside through a transparent plate 13 which equips the upper cover of the body 3.

En se référant à la figure 2, la vis 7 présente, entre la tête 8 et la partie filetée 9, un corps lisse 15, de diamètre nettement supérieur au diamètre de la partie filetée 9, et inférieur au diamètre intérieur des spires du ressort 6. La différence de diamètre entre le corps lisse 15 et la partie filetée 9 créé un épaulement 16 à la frontière entre ces deux parties de la vis.Referring to Figure 2, the screw 7 has, between the head 8 and the threaded portion 9, a smooth body 15, of diameter significantly greater than the diameter of the threaded portion 9, and less than the inner diameter of the turns of the spring 6 The difference in diameter between the smooth body 15 and the threaded part 9 creates a shoulder 16 at the border between these two parts of the screw.

Dans le mode de réalisation représenté en figure 2, l'écrou 10 est réalisé en une matière plastique moulée, et il présente, du côté de la tête de vis, un embout 18, qui fait saillie, dont la partie interne est taraudée, et dont la surface extérieure est sensiblement cylindrique de révolution.In the embodiment shown in FIG. 2, the nut 10 is made of a molded plastic material, and it has, on the side of the screw head, a tip 18, which projects, the internal part of which is tapped, and whose outer surface is substantially cylindrical in revolution.

Une bague 19 de préférence métallique est engagée sur l'embout 18 et son diamètre intérieur est ajusté au diamètre extérieur de l'embout. La bague 19 empêche une déformation de l'embout notamment son gonflement lorsque, à la suite de la rotation de la vis 7, l'embout 18 arrive contre l'épaulement 16.A ring 19, preferably metallic, is engaged on the end piece 18 and its inside diameter is adjusted to the outside diameter of the end piece. The ring 19 prevents deformation of the end piece, in particular its swelling when, following the rotation of the screw 7, the end piece 18 comes against the shoulder 16.

Le diamètre extérieur de la bague 19 est sensiblement inférieur au diamètre intérieur d'une spire, de telle façon que la bague s'engage à l'intérieur du ressort. De préférence, du côté de la tête de vis, la bague 19 se referme par un retour 20, qui fournit une face d'appui sensiblement verticale dont le rôle sera expliqué ultérieurement.The outside diameter of the ring 19 is substantially less than the inside diameter of a turn, so that the ring engages inside the spring. Preferably, on the side of the screw head, the ring 19 closes with a return 20, which provides a substantially vertical bearing face whose role will be explained later.

En arrière de l'embout 18, l'écrou 10 présente une rondelle 21, de diamètre supérieur à celui de la bague, qui fournit une surface de butée verticale, contre laquelle l'extrémité du ressort vient prendre appui.Behind the end piece 18, the nut 10 has a washer 21, of diameter greater than that of the ring, which provides a vertical abutment surface, against which the end of the spring comes to bear.

La rotation de la vis, dans le sens d'une compression du ressort, est limitée par la venue en butée du retour 20 de la bague 19 contre l'épaulement 16 de la vis.The rotation of the screw, in the direction of compression of the spring, is limited by the abutment of the return 20 of the ring 19 against the shoulder 16 of the screw.

Ce contact entre la bague et l'épaulement de la vis freine la rotation de la vis, ce qui est particulièrement intéressant lorsque la rotation de la vis est provoquée par un outil sur la chaîne de fabrication de l'élément de fixation. En outre, la baque 19 évite le gonflement de l'écrou 10 lorsque l'écrou arrive en butée contre l'épaulement 16 de la vis. On évite ainsi une détérioration des filets de l'écrou 10. Egalement, il faut remarquer que l'utilisation d'une matière plastique pour réaliser l'écrou 10 est économique, mais permet également d'obtenir entre l'écrou et les filets de la vis un coefficient de frottement élevé, ce qui évite un desserrage intempestif de l'ensemble vis/écrou.This contact between the ring and the shoulder of the screw brakes the rotation of the screw, which is particularly advantageous when the rotation of the screw is caused by a tool on the production line of the fixing element. In addition, the cover 19 prevents the swelling of the nut 10 when the nut abuts against the shoulder 16 of the screw. This avoids deterioration of the threads of the nut 10. Also, it should be noted that the use of a plastic material to produce the nut 10 is economical, but also makes it possible to obtain between the nut and the threads of the screw has a high coefficient of friction, which avoids untimely loosening of the screw / nut assembly.

La figure 3 représente l'écrou 10 et la vis 7 en position extrême de compression du ressort 6.FIG. 3 represents the nut 10 and the screw 7 in the extreme compression position of the spring 6.

L'épaulement 16 de la vis est situé à une distance de la tête telle que les spires du ressort 6 sont encore espacées. Ainsi, le ressort peut se comprimer de façon additionnelle en réponse aux mouvements du piston 5 dûs à l'ouverture des ailes. Le ressort garde ainsi une fonction de rappel élastique quelle que soit la position de l'écrou 10.The shoulder 16 of the screw is located at a distance from the head such that the turns of the spring 6 are still spaced. Thus, the spring can be compressed additionally in response to the movements of the piston 5 due to the opening of the wings. The spring thus retains an elastic return function whatever the position of the nut 10.

On a obtenu de bons résultats avec une bague 18 et son retour 20 réalisés en métal, mais ceux-ci pourraient être réalisés en un autre matériau, par exemple une matière plastique de qualité différente de celle de l'écrou 10.Good results have been obtained with a ring 18 and its return 20 made of metal, but these could be made of another material, for example a plastic material of a quality different from that of the nut 10.

Dans le mode de réalisation représenté en figure 2, le piston 5 présente, dans sa partie supérieure, une ouverture 25, qui se présente sous la forme d'une lente longitudinale. Cette ouverture est parcourue par un doigt 26, qui est relié de façon solidaire à l'écrou 10. Avantageusement, le doigt 26 et l'écrou 10 sont réalisés d'une seule pièce par moulage. Le doigt 26 porte, à son extrémité supérieure, l'index 12 qui permet de visualiser l'état de compression du ressort. Cet index 12, ou bien la partie supérieure du doigt 26, prend appui sur les parois latérales de l'ouverture 25 du piston, ce qui empêche que l'écrou 10 soit entraîné en rotation lors de la rotation de la vis.In the embodiment shown in Figure 2, the piston 5 has, in its upper part, an opening 25, which is in the form of a longitudinal slow. This opening is traversed by a finger 26, which is integrally connected to the nut 10. Advantageously, the finger 26 and the nut 10 are made in one piece by molding. The finger 26 carries, at its upper end, the index 12 which makes it possible to view the state of compression of the spring. This index 12, or the upper part of the finger 26, bears on the side walls of the opening 25 of the piston, which prevents the nut 10 from being rotated during the rotation of the screw.

La longueur de l'ouverture 25 est déterminée d'après la course longitudinale de l'écrou 10 le long de la vis, ainsi que la course longitudinale du piston 5 suite aux sollicitations de la chaussure sur l'organe de retenue.The length of the opening 25 is determined from the longitudinal stroke of the nut 10 along the screw, as well as the longitudinal stroke of the piston 5 following the stresses of the shoe on the retaining member.

Ainsi, l'index est réalisé de façon très' simple puisqu'il est réalisé d'une seule pièce avec l'écrou 10. En outre, en plus de sa fonction d'indication, l'index empêche la rotation de l'écrou.Thus, the index is made in a very 'simple way since it is made in one piece with the nut 10. In addition, in addition to its function of indication, the index prevents the rotation of the nut .

La figure 4 représente une variante de réalisation de l'écrou. Selon cette variante, l'écrou comprend un insert métallique 30, qui présente, dans sa partie centrale, un orifice taraudé. Un élément en matière plastique 31 est emboîté sur l'insert, et cet élément se prolonge vers le haut par un doigt 32 surmonté de l'index 12 dont il était question précédemment.Figure 4 shows an alternative embodiment of the nut. According to this variant, the nut comprises a metal insert 30, which has, in its central part, a threaded orifice. A plastic element 31 is fitted onto the insert, and this element is extended upwards by a finger 32 surmounted by the index 12 which was discussed above.

L'insert métallique 30 présente latéralement, au moins une, et de préférence deux fentes 33 parallèles à l'axe de la vis. De façon complémentaire, l'élément 31 présente une, et de préférence deux languettes 34 qui viennent s'engager dans les lentes 33 de l'insert 30. Ces languettes 34 viennent au contact de la partie filetée de la vis, et constituent un frein pour la rotation de la vis par rapport à l'écrou.The metal insert 30 has laterally, at least one, and preferably two slots 33 parallel to the axis of the screw. In a complementary manner, the element 31 has one, and preferably two tongues 34 which engage in the nits 33 of the insert 30. These tongues 34 come into contact with the threaded part of the screw, and constitute a brake for rotation of the screw relative to the nut.

L'écrou, représenté dans les figures 4 et 5, fonctionne de la même manière que l'écrou 10 précédemment décrit, et dans le cas présent, c'est l'extrémité de l'insert qui est située du côté de la tête de vis qui vient buter contre l'épaulement 16 de la vis pour limiter son mouvement de rotation dans le sens d'une compression du ressort.The nut, shown in Figures 4 and 5, operates in the same way as the nut 10 previously described, and in this case, it is the end of the insert which is located on the side of the screw head which abuts against the shoulder 16 of the screw to limit its rotational movement in the direction of compression of the spring.

Comme dans le cas précédent, de préférence, lorsque l'insert 30 est en butée contre l'épaulement 16 de la vis, les spires du ressort 6 ne sont pas jointives, si bien que le ressort conserve encore une certaine course de compression.As in the previous case, preferably, when the insert 30 is in abutment against the shoulder 16 of the screw, the turns of the spring 6 are not contiguous, so that the spring still retains a certain compression stroke.

Naturellement, la présente description n'est donnée qu'à titre indicatif, et l'on pourrait adopter d'autres mises en oeuvre de l'invention sans pour autant sortir du cadre de celle-ci.Naturally, the present description is given for information only, and other implementations of the invention could be adopted without departing from the scope thereof.

Claims (8)

  1. Sub-assembly for elastic return of the position-retention device of an alpine ski binding, comprising a compression spring (6), an adjustment screw (7) completely traversing the spring, a nut (10) forming a support stop for one of the ends of the spring, screwed on the threaded end (9) of the screw, an indicator for visualizing the compression of the spring, and a device (5) of connection with the retention device, movable parallel to the ads of the spring with the movements of the retention device,
    characterized by the fact that the screw has, in its central portion, a shoulder (16) against which the nut (10) comes into abutment in the extreme spring compression position, and that, in this position, the turns of the spring are still spaced apart.
  2. Assembly according to claim 1, characterized by the fact that the nut (10) is made of a plastic material, and that it is partly surrounded by a circular metal ring (19) which prevents the expansion of the nut when it is tightened into abutment against the shoulder (16) of the screw.
  3. Assembly according to claim 1, characterized by the fact that the ring (19) has an outer diameter which is smaller than the inner diameter of the spring (6).
  4. Assembly according to claim 2, characterized by the fact that the metal ring (19) has, on the side of the shoulder (16), a return (20) which extends in the direction of the axis of the screw and which constitutes a face supporting the nut against the shoulder (16) of the screw.
  5. Assembly according to claim 1, characterized by the fact that the nut comprises a threaded metal insert (30) which only partly surrounds the threaded portion of the screw, on which is fitted an element (31) molded of plastic material two tongues (34) of which come to fill up the spaces between the insert and the screw on contact with its threaded portion.
  6. Assembly according to claim 1, characterized by the fact that the nut (10) carries a finger (26) which is guided in a longitudinal direction, that this finger prevents the rotation of the nut and that it carries the indicator (12) displaying the compression of the spring.
  7. Assembly according to claim 6, characterized by the fact that the finger (26,32) is guided by a longitudinal slot (25) of the device (5) of connection with the retention device.
  8. Binding element having a base (2) intended to be fastened to the ski, a body (3), a movable element (4) for retaining the movable boot, characterized by the fact that it has a sub-assembly for the elastic return of the retention device according to any one of the preceding claims.
