Definitions
- the present invention relates to a safety ski binding comprising a plate in two parts pivotally mounted on the ski, around a vertical pivot, and carrying, at the front, anterior holding means intended to maintain the anterior end of a shoe and, at the rear, posterior holding means intended to maintain the heel of the shoe.
- the plate is in two parts, one carrying the heel piece and the other the front stop, so as to allow the distance between the heel piece and the front stop to be adjusted to the length of the sole of the shoe.
- These pivoting plate fasteners are known to offer great security. However, in the event of a fall backwards, no triggering occurs. However, if falls backwards are relatively rare, when they occur they are generally serious. If the skier who jumps on a bump falls heavily on the sliding surface of his skis while being behind, the leg muscles and the knee joint are generally able to absorb the bending force and in this case it is not necessary for the fastening to trigger.
- the binding can also be subjected to a significant moment of force in the vertical plane and in this case also the binding must not trigger.
- the binding is subjected to a pushing force towards the rear and to a torsional moment in the vertical plane.
- the object of the present invention is to produce a safety ski binding with a pivoting plate triggering in the event of a rear fall, but only when the plate is subjected to a pushing force towards the rear.
- the binding according to the invention is characterized in that one of the parts of the plate is a part fixed to the pivot and carries the anterior holding means and the other part, which carries the heel holding means, is movable back relative to the part fixed to the pivot, and against the action of elastic return means.
- the shoe can move backwards by driving the movable part of the plate and compressing the elastic return means of the latter, so that the front end of the shoe is released from its holding means.
- the binding according to the invention also has the important advantage of allowing automatic adaptation to the length of the sole of the shoe, which varies from one model to another for the same size, thanks to the elastic displacement of the part. plate mobile.
- the binding shown comprises a plate 1 pivotally mounted on a ski 2 around a pivot 3.
- the plate 1 comprises a fixed part 4 coming from one piece with a fixed jaw 5 at its end for holding the front part of a shoe 6, and a movable part 7 carrying, at the rear, a heel piece 8 for maintaining the heel of the shoe 6.
- the fixed part 4 of the plate is here made of light alloy and it is provided with a steel plate 9 having a longitudinal rectangular cutout 10 whose long sides are provided with a toothing 11 and 12.
- This toothing is in engagement with the teeth of a rider 13 pivotally mounted on the cylindrical part of a cylindrical support 14 fixed to the ski 2.
- the rider 13 is held on the support 14 by a screw 15.
- the toothed rider 13 and the toothed cutout 10 make it possible to adjust the length between the pivot 3 and the front jaw 5, that is to say to adjust the length of the binding according to the length of the shoe.
- the movable part 7 of the plate extends over and under the fixed plate 4. Its upper part tapers down to near the jaw 5, so that the shoe 6 rests only on this part 7 of the plate.
- Part 7 of the plate extending under part 4 serves for the vertical retention of this part 7 which has a horizontal slot 16 into which the toothed plate penetrates 9.
- Part 7 also has a cutout 17 allowing, firstly, the longitudinal displacement of the plate relative to the pivot 3 and, secondly, access to the screw 15 for adjusting the length of the fixing.
- FIG. 3 it can be seen that the support 14 is fixed to the ski by means of two screws 18 and 19.
- the fixed part 4 of the plate is held vertically by a metal plate 20 of generally rectangular shape whose edges 20a and 20b transverse to the ski are slightly raised obliquely and in the form of arcs of a circle centered on the axis of the pivot 3. These raised edges 20a and 20b are engaged in grooves in part 4 of the plate and can slide in these grooves.
- the plate 20 is itself retained by a hoop 21 fixed to the ski by two screws 22 and 23 ( Figures 3 and 4).
- the movable part 7 of the plate is also held vertically and guided by a metal plate 24 having two vertical edges parallel to the axis of the ski 25 and 26 and two sides transverse to the ski 27 and 28 whose edges are raised, in arcs of a circle centered on the axis of the pivot 3 and engaged in grooves in part 7 in which they can slide during the pivoting of the plate.
- the plate 24 is held vertically by a plate 29 having two levels, one of which extends over the plate 24.
- This plate 29 is fixed to the ski by means of four screws 30, 31, 32 and 33.
- the screws 32 and 33 pass through the plate 24 through two oblong cutouts 35 and 36 so as to allow the plate 24 to move axially.
- a metal plate with a low coefficient of friction 34 is arranged to facilitate the movement of the plate 24.
- the plate 29 has a cutout 37 through which the rear raised edge 27 of the plate 24 passes.
- the plate 29 carries two stops 38 and 39 arranged on each side of the longitudinal axis of the binding and symmetrically to this axis.
- the front edge 40 of the cutout 37 serves as a stop for the plate 24.
- the heel piece 8 comprises a body 41 pivotally mounted on the movable part 7 of the plate by means of a vertical pivot 42.
- This heel piece includes a jaw 43 articulated on the body 41 around an axis 44 to hold the heel of the shoe .
- This jaw 43 is held resiliently by means of a spring 45 acting on the jaw 43 by means of a double lever system 46/47 and a piston 48.
- the lever 47 is articulated around a transverse horizontal axis 49 located just above the pivot 42.
- the lever 46 is itself articulated on the lever 47 at its upper part about a transverse axis 50.
- the slotted lower end of the lever 46 bears against the head 51 of a rod 52 directed in the axis of the fixing and provided with a bearing 53 on which the ends 54a and 55a of two bent levers 54 and 55 are mounted, respectively mounted on a vertical axis 56 and 57 on the movable part 7 of the plate (figure 6).
- the rod 52 ends with a lock 58 intended to lock the heel in rotation on the plate. Consequently, the spring 45 pushes, via the lever 46, the head 51 in the direction of the arrow F1, the levers 54 and 55 therefore tend to rotate in the direction indicated by the arrows while bracing themselves on the fixed stops 38 and 39.
- the reaction of the stops 38 and 39 therefore tends to push the part 7 of the plate towards the front, so that the part 27 of the plate 24 is in abutment against the edge 40.
- the stop could be made in the center, by the rear end of the cutout 17 against the pivot 3.
- the longitudinal elastic return device of the plate could consist of a simple fixed stop and a spring disposed between this stop and the plate on the ski or on the movable part of the plate.
- the binding according to the invention also has the advantage of not requiring precise adjustment of the distance between the heel piece and the front stop, since a too short distance is automatically compensated for by the recoil of the movable part 7 of the plate and the compression of the spring 45, as is the case in the independent heel and toe binding, without plate. There is therefore an automatic adaptation of the binding to the length of the sole of the shoe.

Abstract
Description
La présente invention a pour objet une fixation de ski de sécurité comprenant une plaque en deux parties montée pivotante sur le ski, autour d'un pivot vertical, et portant, à l'avant, des moyens de maintien antérieurs destinés au maintien de l'extrémité antérieure d'une chaussure et, à l'arrière, des moyens de maintien postérieurs destinés au maintien du talon de la chaussure.The present invention relates to a safety ski binding comprising a plate in two parts pivotally mounted on the ski, around a vertical pivot, and carrying, at the front, anterior holding means intended to maintain the anterior end of a shoe and, at the rear, posterior holding means intended to maintain the heel of the shoe.
On connaît de nombreuses exécutions de fixations de skis de sécurité à plaque pivotante. De telles fixations sont décrites, par exemple, dans les documents suivants : AT-B-377 703, US-A-4 165 883, US-A-4 266 806, US-A-4 758 017, US-A-4 294 461, US-A-3 937 480. Toutes ces fixations ont en commun un étrier en avant de la plaque pour le maintien de la partie antérieure de la chaussure et une talonnière se déclenchant, en libérant la chaussure, en cas de chute en avant, le pivotement de la plaque assurant la libération de la chaussure en cas de chute entraînant une forte torsion du pied. Dans certaines de ces fixations la plaque est en deux parties, l'une portant la talonnière et l'autre la butée avant, de manière à permettre d'ajuster la distance entre la talonnière et la butée avant à la longueur de la semelle de la chaussure. Ces fixations à plaque pivotante sont connues pour offrir une grande sécurité. Cependant, en cas de chute en arrière, il ne se produit pas de déclenchement. Or, si les chutes en arrière sont relativement rares, lorsqu'elles se produisent elles sont généralement graves. Si le skieur qui saute sur une bosse retombe lourdement sur la surface de glissement de ses skis en étant en arrière, les muscles des jambes et l'articulation du genou sont généralement capables d'absorber l'effort de flexion et dans ce cas il n'est pas nécessaire que la fixation déclenche. De même, dans le cas d'une pratique du ski en force, avec une position très en arrière, la fixation peut également être soumise à un moment de force important dans le plan vertical et dans ce cas également la fixation ne doit pas déclencher. Par contre, si le skieur tombe sur le dos, la tête en aval et glisse en arrière et que le ski est retenu par son talon, le pied et le genou subissent des efforts dangereux, et la fixation devrait déclencher pour libérer le skieur. Or, dans ce cas, la fixation est soumise à un effort de poussée vers l'arrière et à un moment de torsion dans le plan vertical.Numerous executions of safety ski bindings with pivoting plate are known. Such attachments are described, for example, in the following documents: AT-B-377 703, US-A-4 165 883, US-A-4 266 806, US-A-4 758 017, US-A-4 294 461, US-A-3 937 480. All of these bindings have in common a stirrup in front of the plate for holding the front part of the shoe and a heel piece which releases, releasing the shoe, in the event of a fall in before, the pivoting of the plate ensuring the release of the shoe in the event of a fall causing a strong twist of the foot. In some of these bindings, the plate is in two parts, one carrying the heel piece and the other the front stop, so as to allow the distance between the heel piece and the front stop to be adjusted to the length of the sole of the shoe. These pivoting plate fasteners are known to offer great security. However, in the event of a fall backwards, no triggering occurs. However, if falls backwards are relatively rare, when they occur they are generally serious. If the skier who jumps on a bump falls heavily on the sliding surface of his skis while being behind, the leg muscles and the knee joint are generally able to absorb the bending force and in this case it is not necessary for the fastening to trigger. Similarly, in the case of skiing in force, with a position very far back, the binding can also be subjected to a significant moment of force in the vertical plane and in this case also the binding must not trigger. On the other hand, if the skier falls on his back, his head downstream and slides back and the ski is held by his heel, the foot and the knee undergo dangerous efforts, and the binding should trigger to release the skier. However, in this case, the binding is subjected to a pushing force towards the rear and to a torsional moment in the vertical plane.
Partant de ces considérations, la présente invention a pour but de réaliser une fixation de ski de sécurité à plaque pivotante déclenchant dans le cas d'une chute arrière, mais seulement lorsque la plaque subit un effort de poussée vers l'arrière.Based on these considerations, the object of the present invention is to produce a safety ski binding with a pivoting plate triggering in the event of a rear fall, but only when the plate is subjected to a pushing force towards the rear.
La fixation selon l'invention est caractérisée en ce que l'une des parties de la plaque, est une partie fixée au pivot et porte les moyens de maintien antérieurs et l'autre partie, qui porte les moyens de maintien du talon, est déplaçable en arrière relativement à la partie fixée au pivot, et contre l'action de moyens de rappel élastiques.The binding according to the invention is characterized in that one of the parts of the plate is a part fixed to the pivot and carries the anterior holding means and the other part, which carries the heel holding means, is movable back relative to the part fixed to the pivot, and against the action of elastic return means.
En cas de chute en arrière, accompagnée d'une poussée vers l'arrière, la chaussure peut reculer en entraînant la partie mobile de la plaque et en comprimant les moyens de rappel élastiques de celle-ci, de sorte que l'extrémité antérieure de la chaussure se dégage de ses moyens de maintien.In the event of a fall backwards, accompanied by a backward push, the shoe can move backwards by driving the movable part of the plate and compressing the elastic return means of the latter, so that the front end of the shoe is released from its holding means.
La fixation selon l'invention présente en outre l'avantage important de permettre une adaptation automatique à la longueur de la semelle de la chaussure, qui varie d'un modèle à l'autre pour une même pointure, grâce au déplacement élastique de la partie mobile de la plaque.The binding according to the invention also has the important advantage of allowing automatic adaptation to the length of the sole of the shoe, which varies from one model to another for the same size, thanks to the elastic displacement of the part. plate mobile.

La fixation représentée comprend une plaque 1 montée pivotante sur un ski 2 autour d'un pivot 3. La plaque 1 comprend une partie fixe 4 venue d'une pièce avec une mâchoire fixe 5 à son extrémité pour le maintien de la partie antérieure d'une chaussure 6, et une partie mobile 7 portant, à l'arrière, une talonnière 8 pour le maintien du talon de la chaussure 6.The binding shown comprises a
La partie fixe 4 de la plaque est réalisée ici en alliage léger et elle est munie d'une plaque 9 en acier présentant une découpe rectangulaire longitudinale 10 dont les longs côtés sont munis d'une denture 11 et 12. Cette denture est en prise avec les dents d'un cavalier 13 monté pivotant sur la partie cylindrique d'un support cylindrique 14 fixé au ski 2. Le cavalier 13 est maintenu sur le support 14 par une vis 15. Le cavalier denté 13 et la découpe dentée 10 permettent de régler la longueur entre le pivot 3 et la mâchoire avant 5, c'est-à-dire de régler la longueur de la fixation en fonction de la longueur de la chaussure.The
La partie mobile 7 de la plaque s'étend sur et sous la plaque fixe 4. Sa partie supérieure va en s'amincissant jusqu'à proximité de la mâchoire 5, de telle sorte que la chaussure 6 repose seulement sur cette partie 7 de la plaque. La partie 7 de la plaque s'étendant sous la partie 4 sert à la retenue verticale de cette partie 7 qui présente une fente horizontale 16 dans laquelle pénètre la plaque dentée 9. La partie 7 présente en outre une découpe 17 permettant, d'une part, le déplacement longitudinal de la plaque relativement au pivot 3 et, d'autre part, l'accès à la vis 15 pour le réglage de la longueur de la fixation. A la figure 3, on peut voir que le support 14 est fixé au ski au moyen de deux vis 18 et 19.The
A l'avant, la partie fixe 4 de la plaque est retenue verticalement par une plaque métallique 20 de forme générale rectangulaire dont les bords 20a et 20b transversaux au ski sont légèrement relevés obliquement et en forme d'arcs de cercle centrés sur l'axe du pivot 3. Ces bords relevés 20a et 20b sont engagés dans des gorges de la partie 4 de la plaque et peuvent coulisser dans ces gorges. La plaque 20 est elle-même retenue par un arceau 21 fixé au ski par deux vis 22 et 23 (figures 3 et 4).At the front, the
A l'arrière, la partie mobile 7 de la plaque est également retenue verticalement et guidée par une plaque métallique 24 présentant deux bords verticaux parallèles à l'axe du ski 25 et 26 et deux côtés transversaux au ski 27 et 28 dont les bords sont relevés, en arcs de cercle centrés sur l'axe du pivot 3 et engagés dans des gorges de la partie 7 dans lesquelles elles peuvent coulisser lors du pivotement de la plaque. La plaque 24 est retenue verticalement par une plaque 29 présentant deux niveaux dont l'un s'étend sur la plaque 24. Cette plaque 29 est fixée au ski au moyen de quatre vis 30, 31, 32 et 33. Les vis 32 et 33 traversent la plaque 24 à travers deux découpes oblongues 35 et 36 de manière à permettre à la plaque 24 de se déplacer axialement. Entre la plaque 24 et le ski 2, est disposée une plaque métallique à faible coefficient de frottement 34 pour faciliter le déplacement de la plaque 24. La plaque 29 présente une découpe 37 à travers laquelle passe le bord relevé arrière 27 de la plaque 24. A l'arrière, la plaque 29, porte deux butées 38 et 39 disposées de chaque côté de l'axe longitudinal de la fixation et symétriquement à cet axe. Le bord antérieur 40 de la découpe 37 sert de butée à la plaque 24.At the rear, the
La talonnière 8 comprend un corps 41 monté pivotant sur la partie mobile 7 de la plaque au moyen d'un pivot vertical 42. Cette talonnière comprend une mâchoire 43 articulée sur le corps 41 autour d'un axe 44 pour maintenir le talon de la chaussure. Cette mâchoire 43 est maintenue élastiquement au moyen d'un ressort 45 agissant sur la mâchoire 43 par l'intermédiaire d'un système à double leviers 46/47 et d'un piston 48. Le levier 47 est articulé autour d'un axe horizontal transversal 49 situé juste au-dessus du pivot 42. Le levier 46 est lui-même articulé sur le levier 47 à sa partie supérieure autour d'un axe transversal 50. L'extrémité inférieure fendue du levier 46 s'appuie contre la tête 51 d'une tige 52 dirigée dans l'axe de la fixation et munie d'une portée 53 sur laquelle s'appuient les extrémités 54a et 55a de deux leviers coudés 54 et 55 montés respectivement sur un axe vertical 56 et 57 sur la partie mobile 7 de la plaque (figure 6). La tige 52 se termine par un verrou 58 destiné à verrouiller la talonnière en rotation sur la plaque. Par conséquent, le ressort 45 pousse, par l'intermédiaire du levier 46, la tête 51 dans le sens de la flèche F1, les leviers 54 et 55 ont donc tendance à tourner dans le sens indiqué par les flèches en s'arc-boutant sur les butées fixes 38 et 39. La réaction des butées 38 et 39 a donc tendance à pousser la partie 7 de la plaque vers l'avant, de telle sorte que la partie 27 de la plaque 24 est en butée contre le bord 40.The heel piece 8 comprises a
En cas de chute en arrière avec poussée vers l'arrière, une force F2 est exercée sur la talonnière 8. Cette force F2 s'oppose à la force F1 exercée par le ressort 45. La partie mobile 7 de la plaque recule en comprimant ce ressort 45. La chaussure 6 recule avec la partie mobile 7 de la plaque et se dégage de la mâchoire antérieure 5 pour se libérer entièrement de la fixation.In the event of a fall backwards with pushing backwards, a force F2 is exerted on the heel piece 8. This force F2 is opposed to the force F1 exerted by the
La butée pourrait se faire au centre, par l'extrémité postérieure de la découpe 17 contre le pivot 3.The stop could be made in the center, by the rear end of the
Ce système est bien entendu utilisable avec tous types de fixation arrière, que ce soit une talonnière ou un autre mode de fixation, par exemple un dispositif de fixation intégré à la semelle de la chaussure. Dans tous les cas, le dispositif de rappel élastique longitudinal de la plaque pourrait être constitué d'une simple butée fixe et d'un ressort disposé entre cette butée et la plaque sur le ski ou sur la partie mobile de la plaque.This system is of course usable with all types of rear binding, whether it is a heel or another method of attachment, for example a fastening device integrated into the sole of the shoe. In all cases, the longitudinal elastic return device of the plate could consist of a simple fixed stop and a spring disposed between this stop and the plate on the ski or on the movable part of the plate.
Contrairement aux fixations antérieures à plaque en une pièce, la fixation selon l'invention présente en outre l'avantage de ne pas nécessiter un réglage précis de la distance entre la talonnière et la butée avant, puisqu'une distance trop courte est automatiquement compensée par le recul de la partie mobile 7 de la plaque et la compression du ressort 45, comme c'est le cas dans les fixations à talonnière et butée avant indépendantes, sans plaque. On a donc une adaptation automatique de la fixation à la longueur de la semelle de la chaussure.Unlike the previous one-piece plate bindings, the binding according to the invention also has the advantage of not requiring precise adjustment of the distance between the heel piece and the front stop, since a too short distance is automatically compensated for by the recoil of the
Il convient de relever qu'il n'est pas absolument nécessaire que la partie mobile de la plaque soit maintenue en butée en l'absence de chaussure. Un jeu pourrait subsister alors que le ressort de rappel est détendu. D'autre part les moyens de butée pourraient être prévus dans les moyens élastiques de rappel.It should be noted that it is not absolutely necessary for the movable part of the plate to be held in abutment in the absence of a shoe. A play could remain while the return spring is relaxed. On the other hand, the stop means could be provided in the elastic return means.
