Description

L'invention concerne une fixation déclenchable pour planche de glisse comprenant une première partie solidaire d'une chaussure et une seconde partie destinée à être fixée à la planche de glisse et dans laquelle la première partie est retenue au moins approximativement par ses deux extrémités sur la deuxième partie par des pièces mobiles maintenues en prise avec la première partie sous l'action d'au moins un ressort de manière à libérer la chaussure en cas de chute avant ou arrière, ainsi qu'en torsion.The invention relates to a triggerable fixing for gliding board comprising a first part attached to a shoe and a second part intended to be fixed to the gliding board and in which the first part is retained at least approximately by its two ends on the second part by moving parts held in place taken with the first part under the action of at least a spring so as to release the shoe in the event of fall forward or backward, as well as in torsion.

Une telle fixation est connue du brevet AT 315 040. La semelle de la chaussure est munie d'une pièce métallique en U présentant des logements dans lesquels sont engagés des doigts de retenue dont l'un est monté coulissant contre l'action d'un ressort dans un boítier fixé au ski. Une fixation du même type est décrite dans le brevet AT 317 738. Le brevet US 3 957 280 décrit également une chaussure du même type, dans laquelle les deux doigts de retenue sont montés coulissants contre l'action d'un ou deux ressorts. Dans les fixations décrites dans les brevets US 3 834 723 et 4 191 395, les doigts coulissants de verrouillage sont montés dans la semelle de la chaussure et coopèrent avec des surfaces formées dans deux pièces, respectivement une pièce, fixées au ski. Une solution du même type que celle décrite dans le brevet US 3 957 280 a été reprise dans le brevet US 4 245 409. Ces constructions permettent de supprimer totalement l'ajustement de la fixation à la pointure des chaussures, c'est-à-dire d'avoir une fixation vraiment universelle et permettre de réduire le nombre de pièces. Par contre, ces fixations n'ont jamais pu être vraiment commercialisées car elles présentent un inconvénient majeur : la détérioration des surfaces sensibles de la semelle de la chaussure, c'est-à-dire des surfaces participant directement au déclenchement de la fixation en cas de chute. Ces fixations présentent par contre un avantage intéressant, qui réside dans la possibilité de conformer les extrémités de la chaussure de façon très libre, en particulier de supprimer les trottoirs avant et arrière qui sont nécessaires pour les fixations de ski usuelles, et d'arrondir la face inférieure de la semelle à ses extrémités de manière à faciliter la marche.Such attachment is known from patent AT 315 040. The sole of the shoe is provided with a piece U-shaped metal with housings in which are retained retaining fingers, one of which is mounted sliding against the action of a spring in a case attached to the ski. A fixation of the same type is described in the patent AT 317 738. The patent US 3 957 280 describes also a shoe of the same type, in which the two retaining fingers are slidably mounted against the action of one or two springs. In the bindings described in US Patents 3,834,723 and 4,191,395, sliding locking fingers are mounted in the sole of the shoe and cooperate with surfaces formed in two rooms, respectively one piece, fixed to the ski. A solution of the same type as that described in US Pat. No. 3,957,280 has been repeated in US Patent 4,245,409. These constructions completely remove the adjustment of the shoe size fastening, i.e. to have a truly universal attachment and allow reduce the number of pieces. However, these bindings could never really be sold because they have a major drawback: deterioration of the sensitive surfaces of the sole the shoe, that is to say participating surfaces directly at the release of the fixation in case of fall. However, these fasteners have an advantage interesting, which lies in the possibility of conform the ends of the shoe very free, in particular to remove the front sidewalks and rear which are necessary for the fixings of usual ski, and round the underside of the sole at its ends so as to facilitate market.

Pour palier aux inconvénients des chaussures à fixation intégrée selon l'art antérieur susmentionnée, il a été proposé de réaliser une fixation en trois parties, à savoir une première partie destinée à être fixée à la planche de glisse, une deuxième partie solidaire de la chaussure et une troisième partie reliant les premières et deuxièmes parties, seules les premières et troisièmes parties étant agencées de manière à constituer une liaison déclenchable en cas de chute. La chaussure peut être conventionnelle. De telles fixations sont décrites dans les brevets US 3 918 732, 4 191 395 et dans le brevet FR 2 659 565. Ces fixations sont relativement volumineuses et sont destinées à des chaussures de type conventionnel comportant un trottoir avant et un trottoir arrière pour leurs fixations sur la partie intermédiaire. Une adaptation à la pointure de la chaussure des moyens de fixation de celle-ci sur la partie intermédiaire reste nécessaire. To overcome the disadvantages of shoes with fixation integrated according to the aforementioned prior art, it has been proposed to make a three-part fixing, know a first part intended to be attached to the gliding board, a second part secured to the shoe and a third part connecting the first and second parts, only the first and third parts being arranged so as to constitute a triggerable link in the event of a fall. The shoe can be conventional. Such fasteners are described in US Patents 3,918,732, 4,191,395 and in patent FR 2,659,565. These fasteners are relatively large and are intended for conventional type shoes with a sidewalk front and a sidewalk for their fastenings on the middle part. An adaptation to the size of the shoe means of fixing the latter on the intermediate part remains necessary.

L'invention a pour but de conserver l'indépendance des moyens de déclenchement en torsion et en chute avant que l'on trouve dans les fixations à butée et à talonnière, ce qui permet de mieux maítriser les efforts de déclenchement dans chaque cas.The invention aims to preserve the independence of means for triggering in torsion and in front fall found in the stopper and heel piece, which allows better control of tripping forces in each case.

La fixation selon l'invention est caractérisée en ce que la première partie, solidaire de la chaussure, présente, à l'arrière, une paire de tenons latéraux, et en ce que la seconde partie, solidaire de la planche de glisse, comprend, à l'arrière, une pièce mobile constituée d'un étrier montée pivotant autour d'un axe transversal à la fixation et pivotant autour d'un axe vertical, les bras de cet étrier venant retenir les tenons de la première partie et s'appuyer sur ces tenons par des rampes permettant aux tenons de faire basculer l'étrier contre l'action du ressort lors d'une chute vers l'avant.The binding according to the invention is characterized in that that the first part, integral with the shoe, has a pair of side studs on the back, and in that the second part, integral with the board slides, includes, at the rear, a moving part consisting of a stirrup mounted pivoting about an axis transverse to the binding and pivoting about an axis vertical, the arms of this stirrup coming to retain the let's take part one and build on these hold by ramps allowing the tenons to do tilt the caliper against the action of the spring during a fall forward.

Selon un mode d'exécution de l'invention, la première partie est rigide et solidaire de la semelle et présente, à l'avant, des portées d'appui vertical frontal et la seconde partie, solidaire de la planche de glisse, comprend, à l'avant, une pièce mobile constituée d'une mâchoire destinée à s'appuyer frontalement et verticalement sur les portées d'appui de la première partie, cette mâchoire pouvant basculer dans un plan vertical et dans un plan horizontal contre l'action dudit ressort. According to an embodiment of the invention, the first part is rigid and integral with the sole and has vertical bearing surfaces at the front front and the second part, integral with the board sliding, includes, at the front, a moving part consisting of a jaw intended to rest frontally and vertically on the bearing surfaces of the first part, this jaw being able to tilt in a vertical plane and in a horizontal plane against the action of said spring.

Dans ce cas la partie solidaire de la semelle de la chaussure ne comporte pas de surface sensible susceptible de perturber le déclenchement de la fixation.In this case the integral part of the sole of the shoe does not have a sensitive surface likely to disrupt the onset of fixation.

Le déclenchement en torsion est de préférence contrôlé exclusivement par la mâchoire. A cet effet, l'étrier s'appuie sur le ressort, plus précisément sur un coulisseau poussé par le ressort, par une partie arrondie en arc de cercle centrée sur l'axe vertical de pivotement de l'étrier, de telle sorte que le pivotement de l'étrier ne modifie pas la compression du ressort.The torsional release is preferably controlled exclusively by the jaw. For this purpose, the stirrup is based on the spring, more precisely on a slide pushed by the spring, by a part rounded in an arc centered on the vertical axis of pivoting of the caliper, so that the pivoting the caliper does not change the compression of the spring.

La mâchoire est de préférence articulée par une articulation à rotule lui permettant de basculer en tous sens.The jaw is preferably articulated by a ball joint allowing it to tilt in all sense.

L'étrier est de préférence monté pivotant autour d'un axe horizontal dans un étrier monté pivotant autour d'un pivot central et l'axe de pivotement horizontal de l'étrier de retenue est situé au-dessus de sa base par laquelle l'étrier s'appuie contre son coulisseau.The stirrup is preferably pivotally mounted around a horizontal axis in a stirrup mounted pivoting around of a central pivot and the horizontal pivot axis of the retaining clip is located above its base by which the stirrup leans against its slide.

Le déchaussage peut être exécuté au moyen d'un levier de déchaussage articulé en arrière de l'étrier et agissant sur l'étrier par l'intermédiaire d'une pièce de poussée pour le faire basculer contre l'action du ressort.Heaving can be carried out by means of a lever hinged heaving behind the stirrup and acting on the stirrup through a part thrust to tip it against the action of the spring.

Le déclenchement en chute avant est contrôlé par l'étrier travaillant à la manière d'un levier sollicité par les tenons. Ce mode de retenue est peu sensible à la qualité de surface des tenons et des parties de l'étrier en forme de crochet.The trigger in forward fall is controlled by the stirrup working like a lever by the studs. This method of restraint is not very sensitive to the surface quality of the studs and parts of the hook-shaped stirrup.

L'étrier n'oppose donc pratiquement aucune résistance au déclenchement de la fixation en torsion. La chaussure s'échappe tout d'abord de la mâchoire, puis les tenons s'échappent de l'étrier sans solliciter celui-ci en basculement.The stirrup therefore offers practically no resistance when the torsional fixing is triggered. The shoe first escapes from the jaw, then the studs escape from the stirrup without stressing this one in tilting.

La première partie solidaire de la chaussure pourrait être la semelle elle-même. Les tenons seraient fixés à la semelle dont l'avant présenterait un trottoir conventionnel retenu par une butée de type usuel.The first integral part of the shoe could to be the sole itself. The posts would be attached to the sole of which the front would present a sidewalk conventional retained by a usual type stop.

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

La figure 1 est une vue en perspective de la semelle d'une chaussure assemblée à la fixation.Figure 1 is a perspective view of the sole a shoe assembled to the binding.

La figure 2 est une vue de côté des deux parties assemblées de la fixation.Figure 2 is a side view of the two parts fixing assemblies.

La figure 3 est une vue en perspective de la seconde partie de la fixation destinée à être montée sur une planche de glisse.Figure 3 is a perspective view of the second part of the binding intended to be mounted on a gliding board.

La figure 4 est une vue en coupe axiale, dans le plan de symétrie vertical, de la seconde partie de fixation représentée à la figure 3. Figure 4 is an axial sectional view in the plane of vertical symmetry, of the second fixing part shown in Figure 3.

La fixation est constituée d'une première partie 1 intégrée à une semelle de chaussure et une seconde partie 2 destinée à être fixée sur une planche de glisse.The binding consists of a first part 1 integrated with a shoe sole and a second part 2 intended to be fixed on a plank slips.

La partie 1 présente, à l'avant, une surface d'appui frontale 3 arrondie en arc de cercle autour d'un axe vertical et, de chaque côté de cette surface d'appui frontal, deux portées planes horizontales 4 servant de surface d'appui vertical pour une mâchoire 5 de la fixation, comme ceci sera décrit plus loin en relation avec la seconde partie de la fixation. En arrière, la première partie 1 est munie d'une paire de tenons 6 s'étendant horizontalement de chaque côté de la partie 1, c'est-à-dire de chaque côté de la semelle de la chaussure. Ces tenons 6 sont situés dans une zone rétrécie 7 de la semelle, de manière à ne pratiquement pas dépasser latéralement les côtés de la semelle. Entre les surfaces d'appui 3, 4 et les tenons 6, la partie 1 présente une surface d'appui 8 venant s'appuyer sur la seconde partie 2 de la fixation.Part 1 has a support surface at the front frontal 3 rounded in an arc of a circle around an axis vertical and, on each side of this bearing surface front, two horizontal flat spans 4 serving as vertical bearing surface for a jaw 5 of the fixation, as will be described later in relation with the second part of the binding. Back, the first part 1 is provided with a pair of tenons 6 extending horizontally on each side of the part 1, i.e. on each side of the sole of the shoe. These tenons 6 are located in an area narrowed 7 of the sole, so that practically not protrude laterally from the sides of the sole. Between the bearing surfaces 3, 4 and the tenons 6, the part 1 has a bearing surface 8 coming from lean on the second part 2 of the binding.

La seconde partie de la fixation comprend une plaque de base 9 sur et dans laquelle sont montés les composants de cette seconde partie. A l'avant, la plaque 9 porte la mâchoire 5 présentant, en coupe selon la figure 4, un profil en C dont le bras supérieur présente une large encoche en V ouvert 10 dans laquelle vient s'appuyer la surface d'appui arrondie 3 de la partie 1, la mâchoire 5 venant en outre s'appuyer verticalement sur les portées d'appui 4. Le bras inférieur 11 de la mâchoire 5 s'appuie sur un coulisseau 12 monté coulissant dans une glissière longitudinale 13 de la plaque de base 9. La mâchoire 5 est montée sur une rotule 14 de manière à pouvoir pivoter en tous sens. Le coulisseau 12 est traversé par deux tiges parallèles 15 et 16 filetées dans la zone du coulisseau 12 et en prise avec le coulisseau 12. L'extrémité de ces tiges filetées 15 et 16 est en appui contre un second coulisseau 17 coulissant également dans la glissière 13.The second part of the fixing includes a plate of base 9 on and in which the components are mounted of this second part. At the front, the plate 9 carries the jaw 5 having, in section according to FIG. 4, a C-profile whose upper arm has a wide open V notch 10 in which comes lean on the rounded support surface 3 of part 1, the jaw 5 further coming to rest vertically on the bearing surfaces 4. The lower arm 11 of the jaw 5 rests on a slide 12 mounted sliding in a longitudinal slide 13 of the base plate 9. The jaw 5 is mounted on a ball joint 14 so that it can pivot in all directions. The slide 12 is crossed by two parallel rods 15 and 16 threaded in the zone of the slide 12 and in taken with the slide 12. The end of these rods threaded 15 and 16 is pressed against a second slide 17 also sliding in the slide 13.

Dans sa région arrière, la plaque 9 porte un premier étrier 18 s'étendant transversalement à la plaque 9 et monté pivotant autour d'un axe vertical situé dans le plan de symétrie de la partie 2 de la fixation, au moyen d'un pivot 19 sur lequel l'étrier est retenu verticalement par un écrou 24. Dans ce premier étrier pivotant est monté un second étrier 20 articulé dans l'étrier 18 en deux points opposés 21 et 22 de ses bras de manière à pouvoir basculer autour d'un axe horizontal transversal à la plaque 9 et situé au-dessus de la base de l'étrier. Dans sa partie centrale, l'étrier 20 présente une découpe oblongue 23 permettant son basculement malgré la présence de l'écrou 24. L'étrier 20 présente, vers l'avant, un contour arrondi 25 en arc de cercle centré sur un axe situé en arrière de l'axe du pivot 19 et par lequel l'étrier s'appuie contre un coulisseau 26 monté dans la glissière 13. La non-coïncidence du centre de courbure de l'arrondi 25 et de l'axe du pivot 19 est destinée à assurer le recentrage des étriers, comme ceci sera décrit plus loin. A la figure 3, la largeur de ce coulisseau 26 montre la largeur des coulisseaux 12 et 17. En arrière, l'étrier 20 s'appuie contre une pièce intermédiaire de poussée 27 montée coulissant longitudinalement dans une rainure médiane de la plaque 9 et dont l'autre extrémité s'appuie contre le bec 28 d'un levier de déchaussage volontaire 29 articulé sur la plaque 9 autour d'un axe horizontal transversal 30.In its rear region, the plate 9 carries a first stirrup 18 extending transversely to the plate 9 and mounted pivoting about a vertical axis located in the plane of symmetry of part 2 of the binding, at by means of a pivot 19 on which the stirrup is retained vertically by a nut 24. In this first bracket pivoting is mounted a second bracket 20 articulated in the stirrup 18 at two opposite points 21 and 22 of its arms so that you can tilt around an axis horizontal transverse to plate 9 and located above from the base of the caliper. In its central part, the bracket 20 has an oblong cut 23 allowing its tilting despite the presence of the nut 24. The stirrup 20 has a rounded outline towards the front 25 in an arc centered on a rear axis the axis of the pivot 19 and by which the stirrup rests against a slide 26 mounted in the slide 13. The non-coincidence of the center of curvature of the rounding 25 and the axis of the pivot 19 is intended to ensure the recentering of the stirrups, as will be described more far. In FIG. 3, the width of this slide 26 shows the width of the sliders 12 and 17. At the back, the stirrup 20 leans against an intermediate piece of thrust 27 mounted sliding longitudinally in a middle groove of plate 9 and of which the other end rests against the beak 28 of a lever voluntary heaving 29 articulated on the plate 9 about a horizontal transverse axis 30.

Entre les coulisseaux 17 et 26 est montée une paire de ressorts parallèles 31 travaillant en compression entre les coulisseaux. La précompression des ressorts 31 peut être modifiée au moyen des tiges 15 et 16 dont la rotation permet de modifier la position du coulisseau 17.Between the slides 17 and 26 is mounted a pair of parallel springs 31 working in compression between the slides. The precompression of the springs 31 can be modified by means of rods 15 and 16, the rotation allows to change the position of the slide 17.

Les bras 32 et 33 de l'étrier basculant 20 sont conformés en forme de crochet présentant chacun une rampe supérieure 34 et une rampe inférieure 35. En position chaussée, les bras 32 et 33 sont en appui sur les tenons 6 de la chaussure par leur rampe 35 sous la poussée des ressorts 31.The arms 32 and 33 of the tilting stirrup 20 are shaped like a hook each having a upper ramp 34 and a lower ramp 35. In carriageway position, arms 32 and 33 are supported on the tenons 6 of the shoe by their ramp 35 under the spring thrust 31.

La glissière 13 est recouverte d'une plaque 36 sur laquelle vient s'appuyer la chaussure. Sous la mâchoire 5, la plaque 36 est munie d'une plaquette 37 en matériau facilitant le glissement de la chaussure.The slide 13 is covered with a plate 36 on which rests on the shoe. Under the jaw 5, the plate 36 is provided with a plate 37 in material facilitating the sliding of the shoe.

Pour chausser la fixation, l'utilisateur introduit d'abord les portées 4 sous la mâchoire 5. Lors de cette introduction, les ressorts 31 autorisent un léger relèvement de la mâchoire 5 de telle sorte que celle-ci vient s'appuyer efficacement sur les portées 4. Les tenons 6 viennent ensuite en contact avec les rampes 34 de l'étrier 20 et font basculer celui-ci en arrière, puis les bras 32 et 33 viennent se rabattre sur les tenons 6.To fit the binding, the user introduces first the staves 4 under the jaw 5. During this introduction, the springs 31 allow a slight lifting of the jaw 5 so that the latter effectively relies on spans 4. The tenons then come into contact with the ramps 34 of the stirrup 20 and tilt it back, then the arms 32 and 33 are folded over the let's stick 6.

Lors d'une chute avant, les tenons 6 glissent sur les rampes 35 de l'étrier 20 et font basculer cet étrier en arrière en comprimant les ressorts 31, puis s'échappent de l'étrier. La chaussure peut alors se dégager de la fixation.During a forward fall, the tenons 6 slide on the ramps 35 of the stirrup 20 and tilt this stirrup in rear by compressing the springs 31, then escape of the stirrup. The shoe can then be released from the fixation.

Lors d'une chute avec torsion, la surface d'appui frontale 3 de la chaussure fait pivoter latéralement l'étrier 5 dont le bras inférieur 11 repousse le coulisseau 12 en comprimant les ressorts 31. L'étrier 20 accompagne la chaussure en pivotant avec l'étrier 18, en augmentant légèrement la compression des ressorts en raison du décalage entre le centre de courbure de l'arrondi 25 et l'axe du pivot 19. Après libération de l'étrier cette légère augmentation de la compression des ressorts a pour effet de ramener les étriers en position initiale, c'est-à-dire de les recentrer.During a fall with torsion, the bearing surface front 3 of the shoe rotates laterally the stirrup 5 whose lower arm 11 pushes the slide 12 by compressing the springs 31. The stirrup 20 accompanies the shoe by pivoting with the stirrup 18, slightly increasing the compression of the springs due to the offset between the center of curvature of the round 25 and the axis of the pivot 19. After stirrup release this slight increase in the compression of the springs has the effect of bringing the stirrups in the initial position, i.e. recenter.

Lors d'une chute arrière, les portées 4 font basculer la mâchoire 5 dans un plan vertical pour s'échapper de cette mâchoire. Lors de ce mouvement, les tenons 6 pivotent dans l'étrier 20, puis s'échappent de cet étrier par l'avant.When falling backwards, the spans 4 tilt jaw 5 in a vertical plane to escape from that jaw. During this movement, the tenons 6 pivot in the stirrup 20, then escape from this stirrup from the front.

Pour déchausser volontairement, il suffit d'appuyer sur le levier de déchaussage 29 qui fait basculer en arrière l'étrier 20 par l'intermédiaire de la pièce de poussée 27.To remove shoes voluntarily, just press the release lever 29 which swings in rear stirrup 20 through the part of push 27.

L'arrondi 25 pourrait être remplacé par un simple méplat, c'est-à-dire un arrondi de rayon infini ou par toute autre forme assurant un recentrage des étriers par la poussée du coulisseau 26.Rounding 25 could be replaced by a simple flat, that is to say a rounding of infinite radius or by any other shape ensuring a refocusing of the stirrups by the thrust of the slide 26.

Selon une autre variante le recentrage des étriers 18 et 20 pourrait être assuré par la poussée du coulisseau 26 sur l'étrier 18. Dans ce cas l'arrondi 25 de l'étrier 20 pourrait être centré sur l'axe du pivot 19 et l'étrier 18 s'appuierait contre le coulisseau 26 par une partie arrondie dont le centre est situé en arrière de l'axe du pivot 19 ou par un méplat ou par toute autre forme assurant le recentrage des étriers par le coulisseau 26.According to another variant, the centering of the stirrups 18 and 20 could be ensured by the push of the slide 26 on the caliper 18. In this case the rounding 25 of the bracket 20 could be centered on the axis of the pivot 19 and the stirrup 18 would lean against the slide 26 by a rounded part whose center is located behind from the axis of the pivot 19 or by a flat or by any another form ensuring the refocusing of the stirrups by the slide 26.

Selon une autre variante d'exécution l'articulation à rotule de la mâchoire 5 pourrait être remplacée par un appui de la mâchoire 5 sur deux rampes verticales et une rampe horizontale à la manière de certaines mâchoires de butées avant de fixations conventionnelles à butée et talonnière.According to another variant of execution, the articulation to jaw ball 5 could be replaced with a support of the jaw 5 on two vertical ramps and a horizontal ramp like some front stop jaws of conventional fasteners with toe and heel.
