The heel safety fixing for a ski boot comprises a tubular body open at its ends. This body is rigidly fixed to a sole grip (1a) pivoted about a transverse cam forming part of a stirrup (3) pivoted on a pivoting plate (4) integral with the ski. The body contains a spring compressed between a piston supported on the cam and a stop integral with a adjusting screw. The adjusting screw is axially supported by its head against a bearing surface on the body. The stop consists of a nut mounted on the adjusting screw. The heel safety fixing has a reduced cost.

Description

L'invention concerne une talonnière de fixation de sécurité d'une chaussure sur un ski, comprenant un corps de fixation tubulaire ouvert à ses deux extrémités, rigidement solidaire d'un agrippe-semelle et articulé autour d'une came transversale faisant partie d'un étrier articulé autour d'un axe horizontal sur une plaque montée pivotante sur le ski autour d'un axe sensiblement vertical, ce corps contenant au moins un ressort travaillant en compression entre un piston en appui sur la came et une butée solidaire d'une vis de réglage.The invention relates to a heel for fixing safety of a boot on a ski, comprising a tubular fixing body open to both ends, rigidly secured to a sole grip and articulated around a transverse cam making part of a stirrup articulated around a horizontal axis on a pivotally mounted plate on the ski around a substantially vertical axis, this body containing at least a spring working in compression between a piston resting on the cam and a stop secured to a screw adjustment.

Une telle talonnière, dite à pivot, est décrite dans le brevet CH 397 500. Cette fixation est en outre devenue, avec les années, une image de marque du demandeur. Dans cette talonnière, la butée est constituée par la vis de réglage elle-même en forme de bouchon fileté vissé dans l'extrémité taraudée du corps de fixation. Ce corps de fixation est en forme de tube fermé du côté de l'agrippe-semelle. Une telle exécution nécessite donc la fabrication d'une vis spéciale et le taraudage du corps de fixation. Ces usinages constituent des opérations relativement coûteuses.Such a heel piece, called pivot, is described in the Patent CH 397,500. This fixing has also become, over the years, a brand image of the applicant. In this heel piece, the stop is constituted by the screw adjustment itself in the form of a threaded plug screwed into the threaded end of the fixing body. This body of attachment is in the form of a closed tube on the side of the sole grip. Such an execution therefore requires the manufacture of a special screw and the internal thread fixing body. These machining operations constitute relatively expensive operations.

Du brevet FR 2 034 708 on connaít par ailleurs une talonnière du même type, mais dans laquelle le corps de la'fixation est ouvert du côté de l'agrippe-semelle. La butée réglable est également constituée d'une vis spéciale vissée dans un taraudage du corps de la fixation et la came est montée entre deux ressorts. L'accès à la vis de réglage n'est pas très commode. From patent FR 2 034 708 we also know a heel of the same type, but in which the body of the attachment is open on the side of the sole grip. The adjustable stop also consists of a screw special screwed into a female body thread fixing and the cam is mounted between two springs. Access to the adjusting screw is not very convenient.

La présente invention a pour but de réduire le coût de la fabrication de la talonnière.The object of the present invention is to reduce the cost of the manufacture of the heel piece.

A cet effet, la talonnière selon l'invention est caractérisée en ce que la vis de réglage est en appui axial, par sa tête, contre une portée du corps de fixation et que la butée est constituée d'un écrou monté sur la vis de réglage.To this end, the heel piece according to the invention is characterized in that the adjusting screw is supported axial, by its head, against a span of the body of fixing and that the stopper consists of a nut mounted on the adjusting screw.

Il est aisé de former une portée à l'extrémité supérieure du corps de la fixation en laissant un rebord autour de l'ouverture. On peut alors utiliser une simple vis du commerce à collerette qui vient s'appuyer par sa collerette contre cette portée. Un écrou, par exemple du type écrou à ailettes, peut être utilisé comme butée. Les ailettes peuvent simultanément être utilisées comme index pour l'affichage du réglage de la dureté de la fixation.It is easy to form a staff at the end upper body of the binding leaving a rim around the opening. We can then use a simple commercial screw with flange which comes lean by its collar against this span. A nut, for example of the wing nut type, can be used as a stop. The fins can simultaneously be used as an index for displaying the setting the hardness of the fixation.

Entre la vis et la portée d'appui, on dispose avantageusement une pièce de glissement à faible coefficient de frottement. Cette pièce de glissement assure simultanément l'étanchéité du corps de fixation du côté de la vis de réglage.Between the screw and the bearing surface, there are advantageously a low sliding part coefficient of friction. This sliding piece simultaneously seals the fixing body on the side of the adjusting screw.

La vis avec sa butée, le ressort et le piston sont montés dans le corps de fixation par l'extrémité correspondant à l'agrippe-semelle.The screw with its stop, the spring and the piston are mounted in the fixing body by the end corresponding to the sole grip.

Le réglage continue de se faire par l'extrémité la plus accessible de la talonnière. Adjustment continues to be done at the far end accessible from the heel.

Le dessin annexé représente, à titre d'exemple, un mode d'exécution de la talonnière selon l'invention.The accompanying drawing shows, by way of example, a mode of execution of the heel piece according to the invention.

La figure 1 est une vue en perspective de la talonnière en position fermée sur une chaussure.Figure 1 is a perspective view of the heel in the closed position on a shoe.

La figure 2 est une vue en coupe axiale, selon un plan vertical, du corps de fixation représenté à la figure 1.Figure 2 is an axial sectional view, along a plane vertical, of the fixing body shown in the figure 1.

La figure 3 est un agrandissement de la partie supérieure de la coupe axiale du corps de fixation représentée à la figure 2.Figure 3 is an enlargement of the part upper axial section of the fixing body shown in Figure 2.

La figure 4 est un éclaté de la fixation.Figure 4 is an exploded view of the attachment.

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 1a. Ce corps 1 est articulé autour d'une came 10 faisant partie d'un étrier en forme de U dont les bras 2 et 3 sont articulés sur une plaque de base 4 autour d'un axe horizontal a. La plaque de base 4 est montée pivotante sur le ski de manière connue. Le corps 1 est ouvert à ses deux extrémités, c'est-à-dire également ouvert du côté de l'agrippe-semelle 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 un rebord 1b du corps 1 entourant l'ouverture supérieure du corps 1 et formant une portée d'appui pour la collerette 8a de la vis. 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 2 et 3 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 1a. This body 1 is articulated around a cam 10 forming part of a U-shaped bracket of which arms 2 and 3 are articulated on a base plate 4 around a horizontal axis a. The base plate 4 is pivotally mounted on the ski in a known manner. The body 1 is open at both ends, i.e. also open on the side of the sole grip 1a. he contains a main coil spring 5, working in compression between a piston 6 and a stop 7 in form of nut mounted on a screw 8 provided with a flange 8a by which the screw rests on a rim 1b of the body 1 surrounding the upper opening of the body 1 and forming a bearing surface for the flange 8a of the screw. A sliding washer 9 is interposed between the collar 8a and the bearing 1b. The piston 6 rests on the cam 10 in general shape of cylindrical axis, diametrically crossing the body 1 and whose middle part, which constitutes the cam proper, has a flat 11. Arms 2 and 3 are fixed to the ends of this cam 10 by sections shaped so as to prevent rotation of the cam 10. The body 1 has a bore 12 for its rotation around the cam 10. Inside the spring 5 is further mounted an auxiliary spring 13 which works in compression between piston 6 and a washer 14 retained on a bearing 8b from the end of 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 of 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 17 graduations to read 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.

Le montage des éléments contenus dans le corps 1 se fait par l'ouverture du corps située du côté de l'agrippe-semelle la. On introduit d'abord la vis 8 munie de la rondelle de glissement 9 et de l'écrou 7, puis les ressorts et le piston. Après compression du piston, on met ensuite en place la came 10 puis on fixe les bras 2 et 3 aux extrémités de la came. Le ressort principal 5 peut ensuite être comprimé en faisant tourner la vis 8, ce qui a pour effet d'entraíner la butée 7.The assembly of the elements contained in the body 1 is made by the opening of the body located on the side of the sole grip. We first introduce the screw 8 fitted with the sliding washer 9 and the nut 7, then the springs and the piston. After compression of piston, we then put in place the cam 10 then we fix arms 2 and 3 at the ends of the cam. The spring main 5 can then be compressed by making turn the screw 8, which has the effect of causing the stop 7.

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.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.

L'invention n'est bien entendu pas limitée à l'exemple représenté. En particulier, la vis 8 pourrait s'appuyer axialement par la face frontale de sa tête.The invention is of course not limited to the example represented. In particular, the screw 8 could rest axially by the front face of its head.
