Description

FIXATION ARRIERE DE SECURITE POUR SKI
La présente invention concerne une fixation arrière de sécurité pour ski comprenant un corps destiné à tre fixé sur un ski, une mâchoire agrippe-semelle articulée sur ce corps autour d'un axe transversal et munie d'une rampe coopérant avec un piston poussé par un ressort contre la rampe de manière à tendre à maintenir la mâchoire soit en position rabattue sur la chaussure, soit en position relevée ouverte.SKI SAFETY REAR ATTACHMENT
The present invention relates to a rear safety binding for a ski comprising a body intended to be fixed to a ski, a grip-sole jaw articulated on this body around a transverse axis and provided with a ramp cooperating with a piston pushed by a spring against the ramp so as to tend to hold the jaw either in the folded position on the shoe, or in the raised open position.

Une telle fixation est décrite, par exemple, dans le brevet FR 2 494 591. Dans une telle fixation, le piston exerce une pression considérable sur la rampe de la mâchoire sur laquelle il s'appuie. Cette pression se traduit par des forces de frottement plus ou moins importantes pouvant avoir un effet abrasif sur les surfaces en contact. Il est bien connu de réduire les frottements en utilisant des matériaux présentant un faible coefficient de frottement tels que des acétals.Such an attachment is described, for example, in patent FR 2 494 591. In such an attachment, the piston exerts considerable pressure on the ramp of the jaw on which it rests. This pressure results in more or less significant friction forces which can have an abrasive effect on the surfaces in contact. It is well known to reduce friction by using materials having a low coefficient of friction such as acetals.

La fabrication de pièces moulées en acétal nécessite toutefois des reprises après moulage pour obtenir un bel aspect de surface. En utilisant un polyamide, éventuellement chargé de fibres de verre, il est possible d'obtenir par moulage une pièce présentant l'aspect de surface souhaité. Un tel matériau est toutefois sujet à abrasion et s'il est chargé de fibres de verre, ces fibres de verre ne tardent pas à apparaitre à la surface, provoquant à leur tour une abrasion rapide du piston.The production of acetal molded parts, however, requires rework after molding to obtain a good surface appearance. By using a polyamide, possibly loaded with glass fibers, it is possible to obtain by molding a part having the desired surface appearance. Such a material is however subject to abrasion and if it is loaded with glass fibers, these glass fibers do not take long to appear on the surface, in turn causing rapid abrasion of the piston.

L'invention a pour but de résoudre ce problème.
A cet effet, la fixation arrière selon l'invention est caractérisée en ce que la rampe de la mâchoire agrippesemelle est formée sur une pièce auxiliaire rapportée, en un matériau différent du matériau constituant la mâchoire.The invention aims to solve this problem.
To this end, the rear attachment according to the invention is characterized in that the ramp of the gripping jaw is formed on an attached auxiliary part, made of a material different from the material constituting the jaw.

Ce matériau est, de préférence, un matériau à faible coefficient de frottement ou autolubrifiant, par exemple un acétal, comme le piston. Le piston et la pièce auxiliaire étant des pièces cachées, leur aspect extérieur importe peu.This material is preferably a material with a low coefficient of friction or self-lubricating, for example an acetal, such as the piston. The piston and the auxiliary part being hidden parts, their external appearance does not matter.

La fixation peut tre aussi bien une fixation en trois pièces, c'est-à-dire un corps de fixation, une mâchoire agrippe-semelle et un levier de déchaussage, qu'une fixation en deux pièces, c'est-à-dire une fixation dans laquelle la mâchoire agrippe-semelle et le levier de déchaussage constituent une seule pièce. Dans les deux cas, la rampe de la pièce auxiliaire travaille à la manière d'une came avec le piston.The fastening can be either a three-piece fastening, that is to say a fastening body, a sole grip jaw and a release lever, as well as a two-piece fastening, that is to say a binding in which the grip-sole jaw and the release lever constitute a single piece. In both cases, the ramp of the auxiliary part works like a cam with the piston.

Le dessin annexé représente, à titre d'exemple, un mode d'exécution de l'invention.The accompanying drawing shows, by way of example, an embodiment of the invention.

La figure 1 est une vue de côté de la fixation en position ouverte.Figure 1 is a side view of the attachment in the open position.

La figure 2 est une vue en coupe axiale verticale de la figure 1. FIG. 2 is a view in vertical axial section of FIG. 1.

La fixation représentée comprend un corps de fixation 1 positionnable dans une glissière 2 comme décrit par exemple dans la demande de brevet FR 2 614 545. Sur ce corps 1 est articulée, autour d'un axe transversal 3, une pièce 4 dont la partie avant constitue un agrippesemelle 5 et dont la partie située en arrière de l'axe 3 constitue un levier de déchaussage 6. Ce type de fixation est connu en soi.The attachment shown comprises a fixing body 1 which can be positioned in a slide 2 as described for example in patent application FR 2 614 545. On this body 1 is hinged, around a transverse axis 3, a part 4, the front part of which constitutes a gripper 5 and the part located behind the axis 3 constitutes a heaving lever 6. This type of attachment is known per se.

L'agrippe-semelle 5 est muni d'une pédale 7 sur laquelle vient presser le talon de la chaussure pour rabattre l'agrippe-semelle sur le trottoir arrière de la chaussure. La fixation est en outre munie d'un frein de ski 8.The sole grip 5 is provided with a pedal 7 on which the heel of the shoe comes to press to fold the sole grip on the rear sidewalk of the shoe. The binding is also provided with a ski brake 8.

Le corps de fixation 1 et la pièce 4 sont en polyamide chargé de fibres de verre ou en un matériau similaire permettant d'obtenir, par moulage, un bel aspect de surface.The fixing body 1 and the part 4 are made of polyamide loaded with glass fibers or a similar material making it possible to obtain, by molding, a beautiful surface appearance.

La pièce 4 que l'on appellera par la suite agrippesemelle pour l'identifier, présente intérieurement une paroi transversale 9 délimitant, avec la partie avant 5 de l'agrippe-semelle, un logement 10 présentant un profil trapézoïdal ou en V retourné. Dans cet espace 10 est emboîtée une pièce auxiliaire 11 traversée par l'axe métallique 3 et s'appuyant sur les deux faces latérales du logement 10 par des faces parallèles à ces faces latérales. La pièce auxiliaire 11 présente en outre une partie saillante latérale 12 qui s'appuie sur l'extrémité plane de la nervure 9 et dont la surface extérieure constitue une rampe contre laquelle un piston 13, poussé par un ressort 14, vient s'appuyer de manière connue. Dans la position ouverte représentée au dessin, le piston s'appuie contre la rampe par une première zone 15.The part 4 which will be called subsequently agrippesemelle to identify it, has internally a transverse wall 9 delimiting, with the front part 5 of the sole grip, a housing 10 having a trapezoidal or inverted V profile. In this space 10 is fitted an auxiliary part 11 crossed by the metal axis 3 and resting on the two lateral faces of the housing 10 by faces parallel to these lateral faces. The auxiliary part 11 also has a lateral projecting part 12 which rests on the flat end of the rib 9 and the outer surface of which constitutes a ramp against which a piston 13, pushed by a spring 14, comes to bear. known manner. In the open position shown in the drawing, the piston bears against the ramp by a first zone 15.

Le trou de la pièce 11 traversée par l'axe 3 présente avant montage, dans sa partie médiane, un diamètre légèrement inférieur au diamètre de l'axe métallique 3, de telle sorte que l'axe 3 est introduit à force dans la pièce 11 en dilatant cette dernière qui maintient ainsi solidement l'axe 3 en position. De chaque côté de l'axe 3, la pièce auxiliaire 11 présente des évidements 16 et 17 pour précisément permettre cette dilatation.The hole of the part 11 crossed by the axis 3 has, before assembly, in its median part, a diameter slightly less than the diameter of the metal axis 3, so that the axis 3 is forced into the part 11 by expanding the latter which thus securely maintains the axis 3 in position. On each side of the axis 3, the auxiliary part 11 has recesses 16 and 17 to precisely allow this expansion.

La pièce auxiliaire 11 présente en outre un trou radial 18 aboutissant sur l'axe 3. Ce trou 18 permet d'introduire un lubrifiant.The auxiliary part 11 also has a radial hole 18 terminating on the axis 3. This hole 18 makes it possible to introduce a lubricant.

On rappellera qu'en position chaussée, la pédale 7 est abaissée au niveau de la glissière 2 et la rampe 12 est en appui contre une seconde zone 19 du piston 13. Pour déchausser, on appuie sur le levier 6, la rampe 12 glissant tout d'abord sur la zone 19 du piston pour passer ensuite sur la zone 15, comme représenté.It will be recalled that in the carriageway position, the pedal 7 is lowered at the level of the slide 2 and the ramp 12 is in abutment against a second zone 19 of the piston 13. To take off, the lever 6 is pressed, the ramp 12 sliding completely first on zone 19 of the piston to then pass over zone 15, as shown.

L'invention est également applicable à une fixation en trois pièces telle que représentée dans le document FR 2 494 591. The invention is also applicable to a three-piece attachment as shown in document FR 2 494 591.
