Description

L'invention concerne un dispositif de freinage pour ski, notamment pour ski de fond, permettant aux skieurs de freiner en actionnant le dispositif soit volontairement, soit automatiquement, notamment en cas d'accélération trop brutale du skieur.The invention relates to a braking device for skiing, in particular for cross-country skiing, allowing skiers to brake by actuating the device either voluntarily or automatically, in particular in the event of too sudden acceleration of the skier.

On connaît déjà, par le brevet français n° 2.477.425, un dispositif de freinage pour ski correspondant au préambule de la revendication 1. Ce dispositif de freinage se compose d'un ensemble de pièces mobiles commandées par l'inclinaison de la semelle de la chaussure du skieur. En effet, selon ce dispositif, les chaussures de ski sont solidaires d'une latte de fixation, elle-même en liaison pivotante par rapport au ski, ce qui permet au skieur d'imprimer des mouvements de basculement à la latte de fixation.French patent No. 2,477,425 already discloses a ski braking device corresponding to the preamble of claim 1. This braking device consists of a set of moving parts controlled by the inclination of the sole of the skier's shoe. In fact, according to this device, the ski boots are integral with a binding slat, itself in pivoting connection with respect to the ski, which allows the skier to impart tilting movements to the binding slat.

La partie arrière de cette latte basculante commande un levier amplifiant le mouvement de basculement, et permettant d'agir sur un élément de freinage. Ce dernier est constitué par une lame verticale pénétrant dans la neige en passant dans une ouverture aménagée dans la latte de ski.The rear part of this tilting slat controls a lever amplifying the tilting movement, and making it possible to act on a braking element. The latter consists of a vertical blade penetrating into the snow passing through an opening in the ski batten.

Avec un tel dispositif de freinage, complexe et encombrant, le skieur ne peut pas poser ses pieds bien à plat sur les skis, ce qui est pourtant indispensable aussi bien dans la pratique du ski alpin que pendant les phases de descente en ski de fond.With such a complex and bulky braking device, the skier cannot place his feet flat on the skis, which is however essential both in alpine skiing and during the downhill phases in cross-country skiing.

En outre, le fait que l'élément de freinage passe dans une ouverture aménagée dans le ski, celui-ci s'en trouve considérablement fragilisé.In addition, the fact that the braking element passes through an opening in the ski, the latter is considerably weakened.

La présente invention a pour but de remédier à ces inconvénients. L'invention, telle qu'elle est caractérisée dans les revendications, résout le problème consistant à créer un dispositif de freinage pour ski fiable et simple, permettant au skieur de freiner en actionnant le dispositif soit volontairement, soit automatiquement, notamment en cas d'accélération trop brutale, de façon à améliorer la sécurité lors de la pratique de ce sport. A cet effet, ce dispositif de freinage comporte des griffes mobiles recourbées pouvant être actionnées latéralement et en-dessous de la latte de ski, de façon à être plantées dans la neige.The present invention aims to remedy these drawbacks. The invention, as characterized in the claims, solves the problem of creating a reliable and simple ski braking device allowing the skier to brake by actuating the device either voluntarily or automatically, in particular in the event of acceleration too brutal, so as to improve safety when practicing this sport. To this end, this braking device comprises curved movable claws which can be actuated laterally and below the ski batten, so as to be planted in the snow.

Les avantages obtenus grâce à cette invention consistent essentiellement en ceci que l'ampleur du freinage obtenu est déterminée tout-à-fait naturellement par la position du skieur sur les skis, et que le freinage a lieu à chaque fois que le skieur a tendance, volontairement ou non, à basculer vers l'arrière.The advantages obtained thanks to this invention consist essentially in that the extent of the braking obtained is determined quite naturally by the position of the skier on the skis, and that the braking takes place whenever the skier has a tendency, voluntarily or not, to tilt backwards.

De plus, le dispositif de freinage tel qu'il est décrit ci-après peut aisément être utilisé sur des skis standards, sans avoir à modifier et donc fragiliser ceux-ci.In addition, the braking device as described below can easily be used on standard skis, without having to modify and therefore weaken them.

L'invention est exposée ci-après plus en détail à l'aide de dessins représentant seulement un mode d'exécution.The invention is set out below in more detail with the aid of drawings representing only one embodiment.

  • La figure 1 représente une vue en élévation du dispositif de freinage fixé sur le ski et la chaussure du skieur.Figure 1 shows an elevational view of the braking device attached to the ski and the skier's boot.
  • La figure 2 représente une vue partielle du dispositif de freinage, montrant par le dessus les moyens de freinage mobiles en position repos.2 shows a partial view of the braking device, showing from above the mobile braking means in the rest position.
  • La figure 3 représente une vue selon la coupe III-III de la figure 2.FIG. 3 represents a view according to section III-III of FIG. 2.
  • La figure 4 représenté une vue de dessus représentant les moyens de freinage mobiles en position de freinage.Figure 4 shows a top view showing the mobile braking means in the braking position.
  • La figure 5 représente une vue selon la coupe V-V de la figure 4.FIG. 5 represents a view according to section V-V of FIG. 4.

Les figures représentent l'ensemble du dispositif de freinage 1 pour ski, notamment pour ski de fond, comprenant principalement deux parties : d'une part, un ensemble de moyens de freinage mobiles 3 destinés à s'enfoncer dans la neige ou dans la glace pour ralentir le skieur, et d'autre part, un ensemble de moyens autorégulateurs de commande 4 permettant la transmission du mouvement de la jambe 5 du skieur aux moyens de freinage mobiles 3.The figures show the entire braking device 1 for skiing, in particular for cross-country skiing, comprising mainly two parts: on the one hand, a set of mobile braking means 3 intended to sink into snow or ice to slow down the skier, and on the other hand, a set of self-regulating control means 4 allowing the transmission of the movement of the leg 5 of the skier to the mobile braking means 3.

Selon l'invention, les moyens de freinage mobiles 3 sont constitués par deux griffes 6 mobiles destinées à être enfoncées dans la neige ou dans la glace latéralement et/ou en-dessous des skis 2 lors du freinage et ainsi, de provoquer le ralentissement du skieur.According to the invention, the mobile braking means 3 are constituted by two movable claws 6 intended to be driven into the snow or into the ice laterally and / or below the skis 2 during braking and thus cause the skier to slow down.

A cet effet, les griffes mobiles 6, de préférence métalliques, possèdent une extrémité 7 affectant de préférence la forme d'une hélicoide, c'est-à-dire qu'elle est recourbée à la fois vers l'arrière et vers la partie inférieure 8 du ski. Les griffes mobiles 6 comportent en outre une partie rectiligne 9 qui est engagée dans une goulotte 10 aménagée dans une plaque de fixation 11. De ce fait, les griffes mobiles 6 sont libres en rotation dans la goulotte 10 de la plaque de fixation 11, mais sont bloquées en translation par l'intermédiaire de leur autre extrémité 12 qui est recourbée afin de fournir un arrêt 13.For this purpose, the movable claws 6, preferably metallic, have an end 7 preferably affecting the shape of a helicoid, that is to say that it is bent both backwards and towards the part lower 8 of the ski. The movable claws 6 furthermore comprise a rectilinear part 9 which is engaged in a trough 10 arranged in a fixing plate 11. Therefore, the movable claws 6 are free to rotate in the trough 10 of the fixing plate 11, but are blocked in translation by means of their other end 12 which is bent in order to provide a stop 13.

Bien évidemment, du fait de la forme particulière de l'extrémité recourbée 7 des griffes mobiles 6, tant que celles-ci ne sont pas contraintes à rentrer dans la neige ou dans la glace, elles ne font que glisser sur cette neige ou cette glace, sans procurer de freinage. Par contre, selon l'invention, une pression verticale sur les griffes mobiles 6 provoque la rotation de celles-ci vers le bas et, par conséquent, leur pénétration dans la neige, à laquelle elles opposent une résistance, qui est à l'origine du freinage du skieur.Obviously, because of the particular shape of the curved end 7 of the movable claws 6, as long as these are not forced to enter the snow or in the ice, they only slide on this snow or this ice , without providing braking. On the other hand, according to the invention, vertical pressure on the movable claws 6 causes them to rotate downwards and, consequently, their penetration into the snow, to which they oppose a resistance, which is at the origin braking of the skier.

Il est donc nécessaire pour que le dispositif de freinage soit complet de disposer de moyens de commande qui soient aptes à provoquer la pénétration des griffes mobiles 6 dans la neige lors du freinage.It is therefore necessary for the braking device to be complete to have control means which are capable of causing the mobile claws 6 to penetrate into the snow during braking.

A cet effet, le dispositif de freinage pour ski 1 comporte les moyens de commande 4 des griffes mobiles 6. Selon l'invention, ces moyens de commande 4 dont est pourvue la chaussure de ski 14 sont principalement constitués par un manchon 15 relié à un étrier 16 par l'intermédiaire d'une tige 17. Le manchon 15 entourant la jambe du skieur est positionné au niveau de la zone 18 correspondant à la partie inférieure du tibia et est maintenu par un dispositif de serrage 19 quelconque. Le manchon 15 est en outre solidarisé latéralement par rapport à la chaussure 14 par l'intermédiaire des pattes 20 munies d'une articulation adéquate 21.To this end, the ski braking device 1 comprises the control means 4 for the movable claws 6. According to the invention, these control means 4 with which the ski boot 14 is provided are mainly constituted by a sleeve 15 connected to a stirrup 16 by means of a rod 17. The sleeve 15 surrounding the skier's leg is positioned at the level of the zone 18 corresponding to the lower part of the tibia and is held by any clamping device 19. The sleeve 15 is also secured laterally with respect to the shoe 14 by means of the tabs 20 provided with an adequate articulation 21.

Le manchon 15 est, en outre, pourvu au niveau de la zone 22 correspondant à la partie située au-dessus du tendon d'Achille du skieur, d'une coquille rigide 23 destinée à transmettre les mouvements de flexion de la jambe 5 du skieur à la tige 17. A cet effet, la coquille 23 est notamment pourvue d'une rotule 24 coopérant avec l'extrémité 25 de la tige 17.The sleeve 15 is, moreover, provided at the level of the zone 22 corresponding to the part situated above the Achilles tendon of the skier, with a rigid shell 23 intended to transmit the flexion movements of the skier's leg 5 to the rod 17. To this end, the shell 23 is in particular provided with a ball joint 24 cooperating with the end 25 of the rod 17.

L'étrier 16 est relié, d'une part, à la semelle 26 de la chaussure 14 par l'intermédiaire des extrémités 27 et, d'autre part, à l'extrémité 28 de la tige 17 par l'intermédiaire de son extrémité 29. Dans un mode de réalisation préférentiel de l'invention, l'étrier 16 est mobile en rotation autour des extrémités 27 coopérant avec un moyen d'articulation 30 quelconque situé sur la chaussure 14. Lors de l'utilisation du dispositif de freinage pour ski conforme à l'invention, un mouvement vers l'arrière de la jambe 5 du skieur est transmis aux griffes mobiles 6 par l'intermédiaire des moyens de commande 4 constitués par le manchon 15, la tige 17 et l'étrier 16.The stirrup 16 is connected, on the one hand, to the sole 26 of the shoe 14 via the ends 27 and, on the other hand, to the end 28 of the upper 17 via its end 29. In a preferred embodiment of the invention, the stirrup 16 is movable in rotation around the ends 27 cooperating with any articulation means 30 located on the shoe 14. When using the braking device for ski according to the invention, a rearward movement of the skier's leg 5 is transmitted to the movable claws 6 via the control means 4 constituted by the sleeve 15, the rod 17 and the stirrup 16.

Le fonctionnement de ce dispositif de freinage sera mieux compris en se référant aux figures 2, 3, 4 et 5.The operation of this braking device will be better understood by referring to Figures 2, 3, 4 and 5.

Sur la figure 2 apparaît la position du talon 31 de la chaussure 14 du skieur, qui est, par ailleurs, immobilisée par l'intermédiaire du cale- pied 32 (figure 1). Sur les figures 2 et 3, les griffes mobiles 6 apparaissent en position de repos, c'est-à-dire en dehors d'une phase de freinage, le skieur ayant ses jambes 5 fléchies vers l'avant. De ce fait, l'étrier 16 n'est pas appliqué sur les griffes mobiles 6 qui sont en position haute et ne sont pas enfoncées dans la neige. Par conséquent, elles ne procurent pas d'effet de freinage dans cette position.In Figure 2 appears the position of the heel 31 of the shoe 14 of the skier, which is, moreover, immobilized by means of the footrest 32 (Figure 1). In FIGS. 2 and 3, the movable claws 6 appear in the rest position, that is to say outside of a braking phase, the skier having his legs 5 bent forward. Therefore, the stirrup 16 is not applied to the movable claws 6 which are in the high position and are not driven into the snow. Consequently, they do not provide a braking effect in this position.

Par contre, sur les figures 4 et 5, les griffes mobiles 6 sont représentées dans une phase de freinage, pendant laquelle le skieur s'est redressé, c'est-à-dire que l'étrier 16 est plaqué sur les griffes mobiles 6 qu'il force à pénétrer dans la neige latéralement et en-dessous du ski 2 provoquant, de ce fait, un effet de freinage.On the other hand, in FIGS. 4 and 5, the movable claws 6 are shown in a braking phase, during which the skier has straightened up, that is to say that the stirrup 16 is pressed against the movable claws 6 that it forces to penetrate into the snow laterally and below the ski 2, thereby causing a braking effect.

Il est à noter que le fonctionnement du dispositif de freinage pour ski conftoen a line ention est autorégulateur. En effet, il est évident que si le freinage devient trop intense, le skieur a tendance à tomber vers l'avant, donc à fléchir ses jambes et; par conséquent, à permettre aux griffes mobiles 6 de remonter en position de repos, ce qui correspond à la fin du freinage.It should be noted that the operation of the braking device for ski conftoen a line ention is self-regulating. Indeed, it is obvious that if the braking becomes too intense, the skier tends to fall forward, therefore to bend his legs and; therefore, to allow the movable claws 6 to go back to the rest position, which corresponds to the end of braking.

A l'inverse, en cas d'accélération trop brutale ou de déséquilibre arrière, notamment dans le cas d'une descente, le skieur aura tendance à tomber vers l'arrière et à prendre appui sur les talons. De ce fait, l'étrier 16 sera appliqué sur les griffes mobiles 6, ce qui correspond au début d'une phase de freinage permettant au skieur de rétablir son équilibre.Conversely, in the event of too sudden acceleration or rear imbalance, especially in the case of a descent, the skier will tend to fall backwards and lean on the heels. Therefore, the stirrup 16 will be applied to the movable claws 6, which corresponds to the start of a braking phase allowing the skier to restore his balance.

Il est à noter, en outre, que la plaque de fixation 11 positionnant les griffes mobiles 6 peut être pourvue d'un réglage longitudinal adéquat afin de positionner les griffes idéalement en fonction de la taille du pied du skieur.It should be noted, moreover, that the fixing plate 11 positioning the movable claws 6 can be provided with an adequate longitudinal adjustment in order to position the claws ideally as a function of the size of the skier's foot.

Enfin, selon un autre mode de réalisation prévu pour la présente invention, les griffes mobiles 6 peuvent être solidarisées directement avec l'étrier 16 de façon à se déplacer avec lui, plutôt que d'être fixées sur le ski 2, ce qui permet de n'apporter à celui-ci aucune modification.Finally, according to another embodiment provided for the present invention, the movable claws 6 can be secured directly with the stirrup 16 so as to move with it, rather than being fixed on the ski 2, which makes it possible to do not make any changes to it.

Bien entendu, la détermination de la forme optimale des extrémités 7 des griffes mobiles 6 est à la portée de l'Homme de l'Art afin d'obtenir le meilleur freinage possible, d'une part, et afin de permettre, d'autre part, aux griffes mobiles 6 de rester en position de repos par simple réaction de la neige en dehors d'une phase de freinage.Of course, the determination of the optimal shape of the ends 7 of the movable claws 6 is within the reach of the skilled person in order to obtain the best possible braking, on the one hand, and in order to allow, on the other hand hand, movable claws 6 to remain in the rest position by simple reaction of the snow outside a braking phase.

Parmi les avantages relatifs au dispositif de freinage conforme à l'invention, on peut noter qu'en dehors d'une augmentation de la sécurité, ce dispositif de freinage se comporte également comme un frein anti-recul ou comme un frein permettant de récupérer plus facilement les skis perdus suite à une chute.Among the advantages relating to the braking device according to the invention, it can be noted that apart from an increase in safety, this braking device also behaves as an anti-recoil brake or as a brake allowing to recover more easily skis lost due to a fall.
