The lower part of the reinforcing has horizontal edges (31,32) which are engaged along the lateral edges of the runner. The horizontal edges of the side plates (33,34) are covered with anti-friction material and extends continuously from the runners. <IMAGE>

Description

L'invention concerne un élément de fixation pour maintenir une chaussure en appui sur une planche de glisse, notamment sur un ski alpin.The invention relates to a fastening element for keeping a shoe in abutment on a gliding board, in particular on an alpine ski.

Plus précisément, l'invention concerne un élément de fixation présentant un corps qui est monté de façon coulissante le long d'une glissière solidarisée au ski.More specifically, the invention relates to a fastening element having a body which is slidably mounted along a slide secured to the ski.

De nombreux éléments de fixation de ce type existent sur le marché, ou sont connus, par exemple d'après les demandes de brevet français publiées sous le numéro 2 338 060 et 2 494 591.Many fasteners of this type exist on the market, or are known, for example from French patent applications published under the numbers 2 338 060 and 2 494 591.

Habituellement, ces éléments de fixation comprennent un corps de fixation monté coulissant le long d'une glissière longitudinale, par l'intermédiaire de patins de coulissement engagés sur les bords longitudinaux de la glissière qui interdisent tout mouvement vertical relatif entre le corps et la glissière. Ils comprennent aussi une mâchoire de retenue de la chaussure qui est articulée sur le corps de fixation de façon à pouvoir basculer entre une position de retenue de la chaussure et une position de libération.Usually, these fixing elements comprise a fixing body mounted to slide along a longitudinal slide, by means of sliding shoes engaged on the longitudinal edges of the slide which prevent any relative vertical movement between the body and the slide. They also include a shoe retaining jaw which is articulated on the binding body so as to be able to switch between a shoe retaining position and a release position.

Généralement, un organe de verrouillage guidé dans le corps et repoussé par un ressort rappelle élastiquement la mâchoire de retenue vers l'une ou l'autre de ces deux positions qui sont des positions stables.Generally, a locking member guided in the body and pushed back by a spring resiliently recalls the retaining jaw towards one or the other of these two positions which are stable positions.

En outre, un levier de déchaussage volontaire articulé autour d'un axe transversal porté par le corps ou l'organe de verrouillage permet de faire passer volontairement la mâchoire de sa position de retenue à sa position de libération.In addition, a voluntary release lever articulated around a transverse axis carried by the body or the locking member makes it possible to voluntarily move the jaw from its retaining position to its release position.

Ces différents éléments exercent sur le corps des contraintes qui dépendent de la raideur du ressort de rappel et du réglage de pré-contrainte qu'on lui applique. La raideur du ressort et sa précontrainte définissent la dureté de l'élément de fixation, c'est-à-dire l'intensité de l'effort qui doit être appliqué à la mâchoire pour provoquer son passage vers la position de libération. Cette intensité est aussi appelée la valeur de déclenchement de l'élément de fixation.These various elements exert stresses on the body which depend on the stiffness of the return spring and on the pre-stress adjustment applied to it. The stiffness of the spring and its pretension define the hardness of the fastening element, that is to say the intensity of the force which must be applied to the jaw to cause it to pass towards the release position. This intensity is also called the trigger value of the fixing element.

Les éléments de fixation dont la dureté est élevée présentent généralement un corps réalisé en métal, par exemple en un alliage d'aluminium. Un tel corps résiste bien aux contraintes auxquelles il est soumis. Toutefois, son coût est élevé et sa fabrication nécessite des opérations d'assemblage relativement complexes.Fastening elements with high hardness generally have a body made of metal, for example an aluminum alloy. Such a body resists well the constraints to which it is subjected. However, its cost is high and its manufacture requires relatively complex assembly operations.

Ainsi, pour les éléments de fixation de dureté plus faible, on utilise des corps moulés en matière plastique. De tels corps présentent un coût de revient plus faible et leur fabrication est simple.Thus, for the lower hardness fasteners, molded plastic bodies are used. Such bodies have a lower cost price and their manufacture is simple.

Cependant, pour des réglages de dureté élevés, on a constaté des déformations élastiques du corps qui génèrent des frottements entre les différents éléments mobiles. Ces déformations perturbent le fonctionnement de l'élément de fixation et augmentent la dispersion des valeurs de déclenchement.However, for high hardness settings, elastic deformations of the body have been found which generate friction between the different moving elements. These deformations disturb the operation of the fastening element and increase the dispersion of the trigger values.

En outre, ils peut arriver que certaines contraintes particulièrement élevées dégradent de façon irréversible le corps au fil du temps, par exemple par des cassures.In addition, it may happen that certain particularly high stresses irreversibly degrade the body over time, for example by breaks.

Un des buts de l'invention est de proposer un élément de fixation dont le corps est réalisé essentiellement en matière plastique, mais présente une résistance plus élevée aux contraintes auxquelles il est soumis que les corps actuellement connus.One of the aims of the invention is to provide a fastening element whose body is made essentially of plastic, but has a higher resistance to the stresses to which it is subjected than the bodies currently known.

Un autre but est de proposer un élément de fixation dont le corps est plus résistant, donc moins sensible aux déformations élastiques.Another object is to provide a fastening element whose body is more resistant, therefore less sensitive to elastic deformations.

Un autre but de l'invention est de proposer un élément de fixation dont le corps est simple à réaliser et présente un coût relativement faible.Another object of the invention is to provide a fastening element whose body is simple to produce and has a relatively low cost.

Ces buts et d'autres buts qui apparaîtront au cours de la description qui va suivre sont atteints par l'élément de fixation selon l'invention tel qu'il est défini ci-après.These aims and other aims which will appear during the description which follows are achieved by the fastening element according to the invention as defined below.

L'élément de fixation comporte :

  • un corps de fixation monté coulissant le long d'une glissière longitudinale, par l'intermédiaire de patins de coulissement engagés sur les bords longitudinaux de la glissière et interdisant tout mouvement vertical relatif entre le corps et la glissière,
  • une mâchoire de retenue de la chaussure articulée sur le corps de fixation de façon à pouvoir basculer entre une position de retenue de la chaussure et une position de libération.
The fixing element comprises:
  • a fixing body mounted sliding along a longitudinal slide, by means of sliding shoes engaged on the longitudinal edges of the slide and preventing any relative vertical movement between the body and the slide,
  • a shoe retaining jaw articulated on the binding body so as to be able to switch between a shoe retaining position and a release position.

Il est caractérisé par le fait que le corps présente une base réalisée en un matériau relativement peu résistant, et qu'il présente latéralement deux flasques de renfort qui s'étendent au moins entre l'axe d'articulation de la mâchoire et le niveau des patins de coulissement.It is characterized by the fact that the body has a base made of a relatively weak material, and that it laterally presents two reinforcing flanges which extend at least between the axis of articulation of the jaw and the level of the sliding runners.

Les flasques de renforts canalisent les contraintes générées par l'axe d'articulation de la mâchoire et le cas échéant l'axe d'articulation du levier de déchaussage vers la glissière, où ces efforts sont repris. De ce fait, la partie du corps réalisée en matière plastique n'est soumise qu'à des contraintes faibles, et globalement, le corps peut supporter des contraintes plus élevées que les corps traditionnels réalisés entièrement en matière plastique. Il peuvent même supporter des contraintes du même ordre que les corps réalisés en métal.The reinforcement flanges channel the stresses generated by the axis of articulation of the jaw and, where appropriate, the axis of articulation of the release lever towards the slide, where these forces are taken up. Therefore, the part of the body made of plastic material is only subjected to low stresses, and overall, the body can withstand higher stresses than traditional bodies made entirely of plastic material. They can even withstand stresses of the same order as bodies made of metal.

En outre, comme cela apparaîtra dans la description qui va suivre, l'addition des flasques ne complique pas la fabrication du corps outre mesure.In addition, as will appear in the description which follows, the addition of the flanges does not complicate the manufacture of the body beyond measure.

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

La figure 1 illustre l'art antérieur, et représente en vue de côté et en coupe partielle un élément arrière de fixation.Figure 1 illustrates the prior art, and shows a side view and partial section of a rear fixing element.

La figure 2 représente en vue de côté le corps d'un élément de fixation selon un premier mode non limitatif de mise en oeuvre de l'invention.2 shows a side view of the body of a fastening element according to a first non-limiting embodiment of the invention.

La figure 3 représente le corps de la figure 2 en coupe par un plan vertical et transversal.Figure 3 shows the body of Figure 2 in section through a vertical and transverse plane.

La figure 4 est une vue en perspective éclatée du corps des figures 2 et 3.FIG. 4 is an exploded perspective view of the body of FIGS. 2 and 3.

Les figures 5 et 6 sont des figures semblables à la figure 3 et montrent des variantes de mise en oeuvre de l'invention.Figures 5 and 6 are figures similar to Figure 3 and show alternative embodiments of the invention.

La figure 1 illustre l'art antérieur. Elle représente un élément de fixation arrière 1 comprenant un corps 2 monté de façon coulissante le long d'une plaque de base 3 qui est destinée à être assemblée au ski, par tout moyen approprié, par exemple par vissage.Figure 1 illustrates the prior art. It represents a rear fastening element 1 comprising a body 2 slidably mounted along a base plate 3 which is intended to be assembled to the ski, by any suitable means, for example by screwing.

Ainsi que cela est représenté schématiquement dans la figure 1, la plaque de base 3 comprend extérieurement une pièce d'habillage 4, réalisée par exemple en matière plastique. A l'intérieur de la pièce d'habillage se trouve une glissière 5, qui, dans l'exemple représenté a une forme de "C" couché ouvert vers le haut. Le corps 2 est relié à la glissière 5 par des patins 6 qui sont engagés dans les replis latéraux de la glissière. Cet assemblage permet un mouvement de translation du corps le long de la direction définie par la glissière, mais entrave tout mouvement relatif selon une direction perpendiculaire, en particulier verticale.As shown schematically in Figure 1, the base plate 3 externally comprises a covering part 4, made for example of plastic. Inside the covering part there is a slide 5, which, in the example shown has the shape of a "C" lying open up. The body 2 is connected to the slide 5 by pads 6 which are engaged in the lateral folds of the slide. This assembly allows a translational movement of the body along the direction defined by the slide, but hinders any relative movement in a perpendicular direction, in particular vertical.

Le corps 2 porte une mâchoire 7 qui est articulée autour d'un axe transversal 8. La mâchoire permet la retenue de la chaussure.The body 2 carries a jaw 7 which is articulated around a transverse axis 8. The jaw allows the retention of the shoe.

Sur sa face arrière, la mâchoire porte une succession de deux rampes 9 et 10. Un piston 11, guidé en translation dans le corps, est repoussé contre l'une ou l'autre des rampes 9 et 10 par un ressort 12, dont la contrainte initiale est réglable au moyen d'un bouchon fileté 13 qui est vissé dans le corps. Par sa compression, le ressort s'oppose de façon élastique au déplacement de la mâchoire.On its rear face, the jaw carries a succession of two ramps 9 and 10. A piston 11, guided in translation in the body, is pushed against one or the other of the ramps 9 and 10 by a spring 12, the initial stress is adjustable by means of a threaded plug 13 which is screwed into the body. By its compression, the spring resists elastically the movement of the jaw.

Les deux rampes 9 et 10 de la mâchoire définissent ses deux positions stables, c'est-à-dire la position basse de retenue de la chaussure, et la position haute de libération de la chaussure. C'est le ressort 12, par l'intermédiaire du piston 11 qui rappelle la mâchoire dans l'une ou l'autre de ces positions. Les deux rampes sont séparées par une arète 14. L'arète 14 forme la limite entre les deux positions vers lesquelles la mâchoire est rappelée de façon élastique. Lorsque le piston franchit l'arète 14, le ressort 12 se trouve dans un état de compression maximum. La raideur du ressort et la précontrainte qui lui est appliquée par le bouchon 13 déterminent la force de rappel du ressort, et donc la dureté de l'élément de fixation, à laquelle correspond une valeur de déclenchement, c'est-à-dire une valeur de l'effort à appliquer sur la mâchoire pour l'entraîner de sa position de retenue à sa position de libération.The two ramps 9 and 10 of the jaw define its two stable positions, that is to say the low position for retaining the shoe, and the high position for releasing the shoe. It is the spring 12, by means of the piston 11 which recalls the jaw in one or the other of these positions. The two ramps are separated by an edge 14. The edge 14 forms the boundary between the two positions towards which the jaw is returned elastically. When the piston crosses the edge 14, the spring 12 is in a state of maximum compression. The stiffness of the spring and the prestress applied to it by the plug 13 determine the return force of the spring, and therefore the hardness of the fastening element, to which corresponds a trigger value, i.e. a value of the force to be applied to the jaw to drive it from its holding position to its release position.

Un levier de déchaussage 15 permet d'ouvrir volontairement la mâchoire. Le levier présente un grand bras de manoeuvre 16 qui s'étend de bas en haut et d'avant en arrière au dessus du corps.A release lever 15 makes it possible to open the jaw voluntarily. The lever has a large operating arm 16 which extends from bottom to top and from front to back above the body.

Dans le mode de réalisation illustré, le levier est articulé en rotation autour d'un axe 18 porté par le piston 11. Dans sa partie inférieure, il présente deux petits bras 17 parallèles, légèrement incurvés, qui forment une sorte de fourche et qui prennent appui sous deux joues latérales 19 à la face postérieure de la mâchoire.In the illustrated embodiment, the lever is articulated in rotation about an axis 18 carried by the piston 11. In its lower part, it has two small parallel arms 17, slightly curved, which form a sort of fork and which take support under two lateral cheeks 19 at the rear face of the jaw.

Lorsque le levier est actionné pour ouvrir la mâchoire, il prend appui sur son axe 18 pour relever la mâchoire au moyen de ses petits bras 20.When the lever is actuated to open the jaw, it bears on its axis 18 to raise the jaw by means of its small arms 20.

Le lever fait décrire à la mâchoire le même circuit que lors d'une ouverture accidentelle.Raising makes the jaw describe the same circuit as during an accidental opening.

Naturellement, cette construction n'est pas limitative, et il existe de nombreuses autres constructions, notamment des constructions qui mettraient en oeuvre un basculeur articulé à la place du ressort, ou des constructions où la mâchoire et le levier sont portés par le corps autour d'un axe commun. Cette construction met en valeur le fait que le corps 2 est soumis à des contraintes diverses provenant notamment de l'axe d'articulation 8 de la mâchoire, de l'axe d'articulation 18 du levier, du piston, et du ressort.Naturally, this construction is not limiting, and there are many other constructions, in particular constructions which would employ an articulated rocker in place of the spring, or constructions where the jaw and the lever are carried by the body around 'a common axis. This construction highlights the fact that the body 2 is subjected to various stresses originating in particular from the hinge axis 8 of the jaw, from the hinge axis 18 of the lever, of the piston, and of the spring.

Selon la technique antérieure, le corps est réalisé en matière plastique, par moulage, pour des valeurs de déclenchement petites ou moyennes. Par contre, pour des valeurs de déclenchement élevées, le corps de l'élément de fixation est réalisé en métal, par exemple en un alliage d'aluminium.According to the prior art, the body is made of plastic, by molding, for small or medium trigger values. On the other hand, for high trigger values, the body of the fixing element is made of metal, for example an aluminum alloy.

Les figures 2 et 3 illustrent un premier mode de mise en oeuvre de l'invention. Elles représentent un corps 20 dont la forme et les dimensions sont par exemple les mêmes que celles du corps 2 précédent ou d'un corps existant.Figures 2 and 3 illustrate a first embodiment of the invention. They represent a body 20 whose shape and dimensions are for example the same as those of the previous body 2 or of an existing body.

Le corps 20 présente une base 21 réalisée en matière plastique, par exemple par moulage. De façon connue, la base 21 présente un évidement longitudinal prévu pour recevoir l'organe de verrouillage, par exemple un piston ou un basculeur, et le ressort de rappel de cet organe.The body 20 has a base 21 made of plastic, for example by molding. In known manner, the base 21 has a longitudinal recess provided for receiving the locking member, for example a piston or a rocker, and the return spring of this member.

Un renfort 22 en forme de "U" renversé chevauche par ailleurs la base 21 du corps. Le renfort est réalisé en matériau résistant, par exemple en métal, acier, alliage d'aluminium ou en matériau composite. Notamment, le renfort est réalisé à partir d'une tôle découpée puis mise en forme par pliage.A reinforcement 22 in the form of an inverted "U" also overlaps the base 21 of the body. The reinforcement is made of resistant material, for example metal, steel, aluminum alloy or composite material. In particular, the reinforcement is produced from a cut sheet then shaped by folding.

Dans le mode de réalisation des figures 2 à 4, le renfort est rapporté sur la base 21. Selon une autre technique d'assemblage où la base du corps est réalisée par moulage, le renfort pourrait être placé en fond de moule, et la base du corps pourrait être ensuite injectée dans le moule.In the embodiment of FIGS. 2 to 4, the reinforcement is attached to the base 21. According to another assembly technique where the base of the body is produced by molding, the reinforcement could be placed at the bottom of the mold, and the base body could then be injected into the mold.

Le renfort présente latéralement deux flasques 23 et 24 réunies dans leur partie supérieure par un pontage 26. Les flasques et le pontage épousent intérieurement le contour extérieur du corps. De préférence, ainsi que cela est montré dans la figure 4, la paroi de la base présente dans la zone du renfort une diminution d'épaisseur, qui correspond à l'épaisseur du renfort, si bien que globalement, les surfaces extérieures du renfort et de la base du corps sont dans le prolongement continu l'une de l'autre.The reinforcement laterally has two flanges 23 and 24 joined in their upper part by a bridging 26. The flanges and the bridging internally match the outer contour of the body. Preferably, as shown in FIG. 4, the wall of the base has a decrease in thickness in the area of the reinforcement, which corresponds to the thickness of the reinforcement, so that overall, the outer surfaces of the reinforcement and from the base of the body are in continuous extension of each other.

Les flasques s'étendent au moins depuis la zone de l'axe 25 d'articulation de la mâchoire, vers le bas, jusqu'aux patins de liaison avec la glissière. De préférence, les flasques couvrent aussi la zone de l'axe d'articulation du levier de déchaussage, si celui-ci est distinct de l'axe de la mâchoire.The flanges extend at least from the region of the axis of articulation of the jaw, downwards, to the connecting pads with the slide. Preferably, the flanges also cover the area of the axis of articulation of the release lever, if the latter is distinct from the axis of the jaw.

A cet effet, les flasques présentent des ouvertures 27, 28, pour le passage de l'axe de la mâchoire, et 29, 30, pour le passage de l'axe du levier de déchaussage. Ces ouvertures sont en regard des ouvertures correspondantes de la base. Leurs dimensions sont de préférence égales ou très légèrement supérieures aux dimensions des ouvertures correspondantes du corps. De cette façon, une sollicitation exercée par un axe est d'abord transmise à la base du corps, c'est-à-dire la partie en matière plastique, qui se déforme jusqu'à ce que les flasques prennent le relais et fournissent la réaction à ces contraintes. On obtient ainsi un transfert progressif des efforts.For this purpose, the flanges have openings 27, 28, for the passage of the axis of the jaw, and 29, 30, for the passage of the axis of the heaving lever. These openings are opposite the corresponding openings in the base. Their dimensions are preferably equal to or very slightly greater than the dimensions of the corresponding openings in the body. In this way, a stress exerted by an axis is first transmitted to the base of the body, that is to say the plastic part, which deforms until the flanges take over and provide the reaction to these constraints. This gives a gradual transfer of forces.

De préférence également, le renfort s'étend seulement dans la partie avant du corps.Preferably also, the reinforcement extends only in the front part of the body.

Les flasques 23 et 24 présentent dans leur partie inférieure un rebord, respectivement 31, 32, orienté vers l'extérieur parallèlement à un plan horizontal. Comme cela est visible dans la figure 3, les rebords 31 et 32 sont engagés dans les replis latéraux 35 et 36 de la glissière 37.The flanges 23 and 24 have in their lower part a rim, respectively 31, 32, oriented towards the outside parallel to a horizontal plane. As can be seen in FIG. 3, the flanges 31 and 32 are engaged in the lateral folds 35 and 36 of the slide 37.

Ainsi, les flasques 23 et 24 du renfort 22 soulagent la partie avant du corps d'une partie au moins des contraintes exercées par l'axe d'articulation de la mâchoire dans la zone des ouvertures 27 et 28, le cas échéant des contraintes exercées par l'axe d'articulation du levier dans la zone des ouvertures 29 et 30. Ils canalisent ces contraintes vers la glissière où elles sont reprises par les replis 35, 36, puis transmises au ski. Les rebords 31 et 32 assurent également le guidage longitudinal du corps le long de sa glissière.Thus, the flanges 23 and 24 of the reinforcement 22 relieve the front part of the body of at least part of the stresses exerted by the axis of articulation of the jaw in the area of the openings 27 and 28, if necessary the stresses exerted by the axis of articulation of the lever in the area of the openings 29 and 30. They channel these constraints towards the slide where they are taken up by the folds 35, 36, then transmitted to the ski. The flanges 31 and 32 also provide longitudinal guidance of the body along its slide.

La partie arrière du corps est soumise principalement à la réaction du ressort. Toutefois, compte tenu de la forme générale de cette partie du corps, de la direction générale et de l'intensité de ces contraintes, celles-ci peuvent être supportées par la base 21 du corps, sans nécessiter de renfort particulier.The rear part of the body is mainly subject to the reaction of the spring. However, taking into account the general shape of this part of the body, the general direction and the intensity of these stresses, these can be supported by the base 21 of the body, without requiring any particular reinforcement.

De préférence, les rebords 31 et 32 des flasques sont pourvus de garnitures de glissement, dans le but de faciliter la translation du corps le long de la glissière. Ces garnitures sont par exemple constituées par un revêtement de matériau antifriction comme le polytétrafluréthylène.Preferably, the flanges 31 and 32 of the flanges are provided with sliding linings, in order to facilitate the translation of the body along the slide. These linings are for example constituted by a coating of anti-friction material such as polytetraflurethylene.

Selon une autre réalisation visible dans les figures 3 et 4, ces garnitures sont constituées par un segment 33, 34, qui prolonge de façon continue les patins qui longent la base 21 du corps. Seul le patin 36 est visible dans la figure 4.According to another embodiment visible in Figures 3 and 4, these linings are constituted by a segment 33, 34, which continuously extends the pads which run along the base 21 of the body. Only the shoe 36 is visible in FIG. 4.

Les segments 33 et 34 ont de préférence en section une forme de "L" renversé, de façon à couvrir les rebords 31 et 32 sur leur face supérieure et leur face verticale extérieure.The segments 33 and 34 preferably have an inverted "L" shape in section, so as to cover the edges 31 and 32 on their upper face and their outer vertical face.

Entre les segments 33 et 34 et le reste de la base du corps se trouve une fente 37, 38, ouverte sur l'avant du corps. La fente présente des dimensions correspondant à celles des flasques 23 et 24, afin de permettre l'engagement par l'avant du renfort sur la base du corps et son maintien. Les flasques sont engagés dans les fentes 37 et 38, et leur rebord 31, 32, viennent se loger dans l'évidement défini par les segments 33 et 34. Pour faciliter le maintien du renfort, on pourrait refermer légèrement ses flasques au repos, de façon qu'une fois en position sur la base du corps ils produisent un pincement.Between the segments 33 and 34 and the rest of the base of the body is a slot 37, 38, open on the front of the body. The slot has dimensions corresponding to those of the flanges 23 and 24, in order to allow engagement from the front of the reinforcement on the base of the body and its maintenance. The flanges are engaged in the slots 37 and 38, and their flange 31, 32, are received in the recess defined by the segments 33 and 34. To facilitate the maintenance of the reinforcement, its flanges could be slightly closed at rest, so that once in position on the base of the body they produce a pinch.

On pourrait également rendre les segments 33 et 34 légèrement divergents, de fonction qu'ils aient une fonction de rattrapage de jeu entre le corps et sa glissière. Tout autre moyen approprié, notamment des déformations locales des segments, peuvent aussi convenir dans ce but.We could also make the segments 33 and 34 slightly divergent, depending on whether they have a backlash function between the body and its slide. Any other appropriate means, in particular local deformations of the segments, may also be suitable for this purpose.

De préférence, le pontage supérieur 26 du renfort est renforcé par une nervure 40 obtenue par déformation locale. Cette nervure s'étend selon une direction principale transversale. Sur sa longueur et en section, elle présente en outre toute forme appropriée.Preferably, the upper bridging 26 of the reinforcement is reinforced by a rib 40 obtained by local deformation. This rib extends in a main transverse direction. Over its length and in section, it also has any suitable shape.

De plus, les flasques présentent de façon préférentielle sous les ouvertures 27 et 28 une pastille en sur-épaisseur, respectivement 41, 42. Ces pastilles localisent la zone de frottement entre la mâchoire et le corps, ou bien entre le levier et le corps, et maintiennent écartées les joues de la mâchoire ou du levier par rapport au corps. Selon une variante de réalisation, les pastilles sont réalisées sur les parois latérales de la base et traversent des orifices réalisés dans les flasques.In addition, the flanges preferably have under the openings 27 and 28 an over-thickness pad, respectively 41, 42. These pads locate the area of friction between the jaw and the body, or between the lever and the body, and keep the cheeks of the jaw or lever away from the body. According to an alternative embodiment, the pellets are made on the side walls of the base and pass through orifices made in the flanges.

Selon une autre variante, les flasques présentent un orifice dans lequel on place des pastilles rapportées. Les pastilles peuvent être en métal ou en matière plastique.According to another variant, the flanges have an orifice in which inserted inserts are placed. The pellets can be made of metal or plastic.

La figure 5 illustre une variante de réalisation. Selon cette variante, le renfort présente deux flaques indépendants 43 et 44. Comme dans le cas précédent, les flasques s'étendent depuis la zone de l'axe d'articulation de la mâchoire, schématisée en 47, jusque les patins 49 et 50 de liaison avec la glissière.FIG. 5 illustrates an alternative embodiment. According to this variant, the reinforcement has two independent puddles 43 and 44. As in the previous case, the flanges extend from the area of the axis of articulation of the jaw, shown diagrammatically at 47, as far as the pads 49 and 50 of connection with the slide.

Ainsi que cela est visible dans la figure 5, les flasques présentent approximativement une forme de "S". Leur partie supérieure est emboîtée sur la partie extérieure de la base 48 du corps. Leur partie inférieure est emboîtée dans la partie inférieure de la base 48 du corps. Leur partie médiane traverse une ouverture des parois latérales du corps, respectivement 45, 46. Comme dans le cas précédent, de préférence, les rebords inférieurs 51, 52, des flasques sont revêtus d'une garniture antifriction qui provient avantageusement de la paroi en matière plastique à la base du corps. Il serait également possible de faire un surmoulage sur les rebords 51 et 52.As can be seen in Figure 5, the flanges have approximately an "S" shape. Their upper part is fitted onto the external part of the base 48 of the body. Their lower part is fitted into the lower part of the base 48 of the body. Their middle part crosses an opening of the side walls of the body, respectively 45, 46. As in the previous case, preferably, the lower flanges 51, 52, the flanges are coated with an anti-friction lining which advantageously comes from the plastic wall at the base from the body. It would also be possible to overmold the edges 51 and 52.

Ce mode de montage est avantageux car il assure un maintien correct des flasques le long du corps. Il n'est cependant pas limitatif, et on pourrait mettre en oeuvre deux flasques indépendants entièrement emboîtés sur la paroi extérieure de la base du corps, c'est-à-dire des flasques sans pontage montés à la façon des flasques 23 et 24. Dans ce cas, ce serait la mâchoire et le levier qui assureraient le maintien des flasques le long de la base du corps.This mounting method is advantageous because it ensures correct retention of the flanges along the body. However, it is not limiting, and two independent flanges could be used which are entirely fitted on the outer wall of the base of the body, that is to say flanges without bridging mounted in the manner of flanges 23 and 24. In this case, it would be the jaw and the lever which would ensure the maintenance of the flanges along the base of the body.

D'autres solutions sont aussi possibles. Par exemple, la base du corps pourrait être surmoulée sur les flasques, c'est-à-dire que les flasques pourraient être encastrés partiellement ou totalement dans les parois latérales de la base 48 au cours de son opération de moulage.Other solutions are also possible. For example, the base of the body could be overmolded on the flanges, that is to say that the flanges could be partially or totally embedded in the side walls of the base 48 during its molding operation.

La figure 6 représente une autre variante. Selon cette variante, la glissière en "C" couché et ouvert vers le haut est remplacée par une glissière à ailes latérales 55 et 56, et c'est la partie inférieure du corps 57 qui est conformée en "C" couché et ouvert vers le bas pour être engagé sur la glissière, permettant ainsi une translation du corps le long de la direction définie par la glissière, et empêchant tout autre mouvement.Figure 6 shows another variant. According to this variant, the slide in “C” lying and open upwards is replaced by a slide with lateral wings 55 and 56, and it is the lower part of the body 57 which is shaped as “C” lying and open towards the low to be engaged on the slide, allowing a translation of the body along the direction defined by the slide, and preventing any other movement.

Comme dans les cas précédemment décrits, le corps 57 présente une base 58 et un renfort 59 qui épousent le contour extérieur de la base.As in the cases described above, the body 57 has a base 58 and a reinforcement 59 which conform to the external contour of the base.

Dans sa partie inférieure, la base présente deux patins qui sont engagés sous les ailes 55 et 56 de la glissière. Les patins ne sont pas visibles dans la figure 6.In its lower part, the base has two pads which are engaged under the wings 55 and 56 of the slide. The skids are not visible in Figure 6.

Les flasques latérales 61 et 62 du renfort 59 présentent quant à eux dans leur partie inférieure deux rebords horizontaux 63 et 64 qui sont engagés sous les ailes 55 et 56 de la glissière. De préférence, les rebords sont revêtus de garnitures de glissement. Ces garnitures sont des segments 65 et 66 qui prolongent les patins de la base et qui couvrent les rebords 63 et 64 sur une face horizontale et une face verticale.The lateral flanges 61 and 62 of the reinforcement 59 have meanwhile in their lower part two horizontal flanges 63 and 64 which are engaged under the wings 55 and 56 of the slide. Preferably, the edges are coated with sliding linings. These linings are segments 65 and 66 which extend the pads of the base and which cover the edges 63 and 64 on a horizontal face and a vertical face.

Les contraintes que l'axe de la mâchoire, schématisé en 68, transmet au corps sont canalisées par les flasques du renfort 58 en direction de la glissière, si bien que la base du corps se trouve soulagée de ces contraintes.The stresses that the axis of the jaw, shown diagrammatically at 68, transmits to the body are channeled by the flanges of the reinforcement 58 in the direction of the slide, so that the base of the body is relieved of these constraints.

Les déformations élastiques du corps sont moins importantes que si le corps était réalisé entièrement en matière plastique. De ce fait, le frottement qui s'oppose au mouvement relatif de l'organe de verrouillage, c'est-à-dire par exemple le piston ou un basculeur, est diminué, et la dispersion des valeurs de déclenchement est plus faible.The elastic deformations of the body are less significant than if the body were made entirely of plastic. Therefore, the friction which opposes the relative movement of the locking member, that is to say for example the piston or a rocker, is reduced, and the dispersion of the trigger values is lower.

L'invention n'est pas limitée aux différents modes de réalisation qui ont été décrits, elle en englobe les variantes, les équivalents et autres constructions tels qu'ils sont définis dans les revendications ci-après.The invention is not limited to the various embodiments which have been described, it encompasses variants, equivalents and other constructions as defined in the claims below.

En particulier, la nature des matériaux utilisés pour le corps et le renfort n'est pas limitative. Le renfort pourrait être réalisé en un matériau composite, notamment une résine chargée de fibres.In particular, the nature of the materials used for the body and the reinforcement is not limiting. The reinforcement could be made of a composite material, in particular a resin loaded with fibers.

L'invention n'est pas non plus limitée à un élément de fixation arrière. Elle s'applique à tout élément de fixation dont le corps porte une mâchoire de retenue.The invention is also not limited to a rear fixing element. It applies to any fixing element whose body carries a retaining jaw.
