Abstract

The ski binding heelpiece comprises a sole clip with a solid tubular body (1) articulated around a transverse cam (10) which is part of a solid, U-shaped stirrup (2) belonging to a pivoting plate. The plate is mounted on a slider, along the length of which it can be positioned from behind. The tubular body has a spring (5) working in compression between a piston (6) pushed against the cam and a thrust (7) with an adjusting screw (8). The cam is a cylinder which serves as a rotational axis for the tubular body and has a flat (11) which extends parallel to the axis, so that the piston pushes against it when the heelpiece is closed. The area of the cam that the piston presses against when the heelpiece is open is conformed in such a way that it limits tipping of the tubular body during opening.

Description

L'invention concerne une talonnière de fixation de sécurité d'une chaussure sur un ski, comprenant un corps de fixation tubulaire rigidement solidaire d'un agrippe-semelle et articulé autour d'une came transversale faisant partie d'un étrier solidaire d'une plaque pivotante montée sur une glissière le long de laquelle elle peut être positionnée par des moyens de positionnement actionnables par l'arrière, le corps de fixation contenant au moins un ressort travaillant en compression entre un piston en appui sur la came et une butée solidaire ou constituée d'une vis de réglage, la came étant formée dans une pièce cylindrique servant d'axe de rotation du corps et présentant un méplat s'étendant parallèlement à l'axe de ladite pièce cylindrique, le piston étant en appui sur ce méplat en position fermée de la talonnière.The invention relates to a heel for fixing safety of a boot on a ski, comprising a tubular fixing body rigidly secured to a sole grip and articulated around a cam transverse part of a stirrup integral with a swivel plate mounted on a slide along which it can be positioned by means of positioning actuated from the rear, the body fastener containing at least one spring working in compression between a piston resting on the cam and a integral stop or consisting of an adjustment screw, the cam being formed in a cylindrical part serving axis of rotation of the body and having a flat extending parallel to the axis of said part cylindrical, the piston being supported on this flat in closed position of the heel.

Une telle talonnière est décrite dans le brevet CH 397 500 et exploitée depuis de nombreuses années par le demandeur. Les moyens de positionnement sont généralement constitués d'une vis longitudinale en prise avec une denture cycloïdale de la glissière, cette vis étant actionnable par un tournevis.Such a heel is described in patent CH 397 500 and operated for many years by the applicant. The positioning means are generally consisting of a longitudinal screw in taken with a cycloidal teeth of the slide, this screw being actuated by a screwdriver.

En position ouverte de cette talonnière, le piston s'appuie sur la partie cylindrique de la came. Le corps de fixation peut donc basculer jusqu'à toucher le ski et gêner ainsi l'accès aux moyens de réglage de la position de la talonnière sur sa glissière.In the open position of this heel piece, the piston rests on the cylindrical part of the cam. The body binding can therefore tilt until it touches the ski and thus hinder access to the means for adjusting the position of the heel piece on its slide.

L'invention a principalement pour but de limiter l'ouverture de la talonnière de manière à laisser libre l'accès aux moyens de réglage de la position de la talonnière sur sa glissière.The main object of the invention is to limit opening the heel so as to leave free access to means for adjusting the position of the heel piece on its slide.

A cet effet, la talonnière selon l'invention est caractérisée en ce que la zone de la came sur laquelle s'appuie le piston en position ouverte de la talonnière, est conformée de manière à limiter le basculement du corps de fixation lors de l'ouverture de la talonnière.To this end, the heel piece according to the invention is characterized in that the area of the cam on which supports the piston in the open position of the heel piece, is shaped so as to limit the tilting of the fixing body when opening the heel.

Selon un premier mode d'exécution, ladite zone consiste en un second méplat, moins important que le premier méplat, mais suffisant pour retenir le corps de fixation grâce à la force importante exercée par le ressort dans cette position. Cette position est en outre stable, ce qui à pour effet d'empêcher une fermeture intempestive et brutale de la talonnière lors d'un choc sur le corps de fixation.According to a first embodiment, said zone consists in a second flat, less important than the first flat but sufficient to hold the body of fixation thanks to the significant force exerted by the comes out in this position. This position is in additionally stable, which effectively prevents unexpected and sudden closure of the heel when a shock on the fixing body.

Selon un second mode d'exécution, ladite zone de la came présente une saillie limitant la rotation de la came relativement au piston. Cette saillie peut présenter une face plane tangente à la partie cylindrique de la came. Cette face plane constitue donc un méplat que l'on ne sent pas lors de la fermeture de la fixation, contrairement à un vrai méplat sécant selon le première mode d'exécution.According to a second embodiment, said zone of the cam has a projection limiting the rotation of the cam relative to the piston. This projection can present a plane face tangent to the part cylindrical of the cam. This flat face therefore constitutes a flat that you do not feel when closing fixation, unlike a real secant flat according to the first embodiment.

Le dessin annexé représente, à titre d'exemple, trois modes d'exécution de la talonnière selon l'invention. The accompanying drawing shows, by way of example, three embodiments of the heel piece according to the invention.

La figure 6 représente la came et le piston en position ouverte selon un troisième mode d'exécution.Figure 6 shows the cam and the piston in position open according to a third embodiment.

Comme la fixation décrite dans le brevet CH 397 500, la fixation représentée se caractérise par un corps cylindrique tubulaire 1 venu d'une pièce avec un agrippe-talon la. Ce corps 1 est articulé autour d'une came 10 faisant partie d'un étrier 2 en forme de U solidaires d'une plaque de base 4 montée pivotante de manière connue sur une embase 24 elle-même montée sur une glissière 25 sur laquelle elle peut être déplacée au moyen d'une vis 26 solidaire de l'embase et en prise avec une denture de la glissière. La glissière est fixée sur un ski 27. Le corps 1 est ouvert à ses deux extrémités, c'est-à-dire également ouvert du côté de l'agrippe-talon 1a. Il contient un ressort hélicoïdal principal 5, travaillant en compression entre un piston 6 et une butée 7 en forme d'écrou monté sur une vis 8 munie d'une collerette 8a par laquelle la vis s'appuie sur une portée 1b du corps 1 entourant l'ouverture supérieure du corps 1. Une rondelle de glissement 9 est interposée entre la collerette 8a et la portée 1b. Le piston 6 s'appuie sur la came 10 en forme générale d'axe cylindrique, traversant diamétralement le corps 1 et dont la partie médiane, qui constitue la came proprement dite, présente un méplat 11. Les bras de l'étrier 2 sont fixés aux extrémités de cette came 10 par des parties profilées de manière à empêcher la rotation de la came 10. Le corps 1 présente un alésage 12 pour sa rotation autour de la came 10. A l'intérieur du ressort 5 est en outre monté un ressort auxiliaire 13 qui travaille en compression entre le piston 6 et une rondelle 14 retenue sur une portée 8b de l'extrémité de la vis 8.Like the attachment described in patent CH 397,500, the attachment shown is characterized by a body cylindrical tubular 1 came in one piece with a heel grip. This body 1 is articulated around a cam 10 forming part of a U-shaped stirrup 2 integral with a pivotally mounted base plate 4 of known manner on a base 24 itself mounted on a slide 25 on which it can be moved by means of a screw 26 secured to the base and in engagement with teeth on the slide. The slide is fixed on a ski 27. Body 1 is open to both ends, i.e. also open on the side of the heel grip 1a. It contains a coil spring main 5, working in compression between a piston 6 and a nut-shaped stopper 7 mounted on a screw 8 provided with a flange 8a by which the screw is supported on a surface 1b of the body 1 surrounding the opening upper part of the body 1. A sliding washer 9 is interposed between the flange 8a and the bearing 1b. The piston 6 rests on cam 10 in general form of cylindrical axis, diametrically crossing the body 1 and whose middle part, which constitutes the cam proper, has a flat 11. The arms of the stirrup 2 are fixed to the ends of this cam 10 by profiled parts so as to prevent rotation of the cam 10. The body 1 has a bore 12 for its rotation around the cam 10. Inside spring 5 is further mounted an auxiliary spring 13 which works in compression between the piston 6 and a washer 14 retained on a bearing 8b of the end of the screw 8.

Le corps 1 présente en outre deux fentes longitudinales 15 et 16 parallèles à l'axe des ressorts et de la vis, disposées de chaque côté du corps 1. La butée 7 est munie de deux bras 7a et 7b engagés dans la fente 15, respectivement 16 et pouvant librement coulisser dans ces fentes. Aux bords des fentes, sont gravées des graduations 17 permettant de lire la position du curseur constitué par l'écrou 7.The body 1 also has two longitudinal slots 15 and 16 parallel to the axis of the springs and the screw, arranged on each side of the body 1. The stop 7 is provided with two arms 7a and 7b engaged in the slot 15, respectively 16 and being able to slide freely in these slots. At the edges of the slots are engraved graduations 17 for reading the position of the cursor formed by nut 7.

Le corps cylindrique 1 est entouré d'une enveloppe 18 en matériau synthétique transparent dans au moins la zone de lecture de l'affichage du réglage. The cylindrical body 1 is surrounded by an envelope 18 made of transparent synthetic material in at least the reading area of the setting display.

Selon un premier mode d'exécution, la came 10 présente un méplat auxiliaire 21 peu profond et perpendiculaire au méplat principal 11.According to a first embodiment, the cam 10 has a shallow and perpendicular auxiliary flat 21 on the main flat 11.

Comme ceci est connu de l'art antérieur, l'ouverture de la talonnière se fait par le basculement du corps 1 autour de la came 10, ce qui a pour effet de repousser le piston 6 et de comprimer les ressorts, comme représenté à la figure 4. Lorsque le piston arrive en appui sur le méplat auxiliaire 21 il est retenu dans cette position stable par la force des ressorts. Il est certes possible de dépasser cette position, mais ceci exige un effort particulier. Le corps 1 occupe la position représentée à la figure 1. Dans cette position l'espace subsistant entre le corps 1 et le ski 27 assure un bon accès à la vis de réglage 26.As is known from the prior art, the opening of the heel is made by tilting the body 1 around cam 10, which has the effect of pushing back piston 6 and compress the springs, as shown in Figure 4. When the piston reaches support on the auxiliary flat 21 it is retained in this stable position by the force of the springs. It is certainly possible to exceed this position, but this requires special effort. Body 1 occupies the position shown in Figure 1. In this position the space remaining between the body 1 and the ski 27 provides good access to the adjusting screw 26.

Selon un second mode d'exécution représenté à la figure 5, la came 10 présente une saillie radiale 22 formant un angle d'environ 35° avec le plan du méplat 11, ce dernier étant un peu plus éloigné du centre de la came que dans le premier mode d'exécution. Lors de l'ouverture de la fixation, le basculement du corps de la fixation 1 est limité par la venue en butée du piston 6 contre la saillie 22. La saillie peut être rapportée ou venue d'une pièce avec la came 10.According to a second embodiment represented in the figure 5, the cam 10 has a radial projection 22 forming an angle of about 35 ° with the plane of the flat 11, this last one a little further from the center of the cam than in the first embodiment. During the opening of the binding, the tilting of the body fixing 1 is limited by the abutment of the piston 6 against the projection 22. The projection can be attached or coming from a part with the cam 10.

Dans le mode d'exécution représenté à la figure 6, la came 10 est munie d'une protubérance 23 formant une surface d'appui plane tangente à la surface cylindrique de la came. Le diamètre passant par le sommet de la protubérance 23 forme un angle d'environ 25° avec le méplat 11. Lors de l'ouverture de la fixation, le piston 6 vient s'appuyer sur la face plane de la protubérance 23.In the embodiment shown in Figure 6, the cam 10 is provided with a protuberance 23 forming a flat bearing surface tangent to the cylindrical surface of the cam. The diameter passing through the top of the protuberance 23 forms an angle of about 25 ° with the flat 11. When the binding is opened, the piston 6 comes to rest on the flat face of the protuberance 23.

Dans les modes d'exécution selon les figures 5 et 6, la came offre une grande résistance contre une rotation du corps de fixation au-delà de la position représentée, alors que la fermeture de la fixation à partir de cette position s'effectue sans rencontrer de résistance particulière.In the embodiments according to FIGS. 5 and 6, the cam provides great resistance against rotation of the fixing body beyond the position shown, while closing the binding from this position is performed without encountering resistance particular.
