Description

La présente invention se rapporte à un dispositif, empêchant un ski de glisser en arrière, comportant un support destiné à être fixé sur le ski et sur lequel au moins un organe de retenue est articulé, cet organe étant susceptible de pivoter d'une position inactive vers une position active dans laquelle, il coopère avec la neige pour empêcher un déplacement du ski vers l'arrière. On connaît déjà un tel dispositif (CH-A-501.413 et GB-A-471.586).The present invention relates to a device, preventing a ski from sliding backwards, comprising a support intended to be fixed on the ski and on which at least one retaining member is articulated, this member being capable of pivoting from an inactive position towards an active position in which it cooperates with the snow to prevent the ski from moving backwards. Such a device is already known (CH-A-501.413 and GB-A-471.586).

Ce dispositif comporte un support sur lequel est articulé une pièce en forme de "U". Les deux bras du "U", qui réalisent des griffes; sont constamment solicités vers une position active, sensiblement verticale par rapport au plan du ski, en contact avec des butées, par un ressort à l'encontre de l'action duquel, lorsqu'on avance le ski, la pièce en "U" agit afin d'être ramenée vers l'arrière.This device comprises a support on which a part in the shape of a "U" is articulated. The two arms of the "U", which carry claws; are constantly solicited towards an active position, substantially vertical with respect to the plane of the ski, in contact with abutments, by a spring against the action of which, when the ski is advanced, the "U" part acts in order to be brought back.

Tel que réalisé, ce dispositif présente l'inconvénient de toujours freiner le ski du fait que les deux bras se trouvent constamment engagés dans la neige de manière incontrôlable y compris dans les descentes.As realized, this device has the disadvantage of always braking the ski because the two arms are constantly engaged in the snow uncontrollably including downhill.

Un autre inconvénient réside dans le fait que le dispositif est susceptible d'être endommagé lorsque, en effectuant un saut, on atterrit verticalement sur les deux bras qui, privés de la résistance de la neige, se seront mis en position de freinage. Pour remédier à ces inconvénients, dans l'un de ces dispositifsconnus (GB-A-501.413) est prévu un moyen de verrouillage des bras dans une position où ils sont totalement inactifs. Malheureusement, pour bénéficier du dispositif lors des montées, un déverrouillage manuel est nécessaire entretemps ce qui est peu compatible avec les fréquents changements de profil du parcours.Another disadvantage lies in the fact that the device is liable to be damaged when, by performing a jump, one lands vertically on the two arms which, deprived of the resistance of the snow, will have put themselves in the braking position. To remedy these drawbacks, one of these known devices (GB-A-501.413) is provided with means for locking the arms in a position where they are completely inactive. Unfortunately, to benefit from the device during the climbs, a manual unlocking is necessary in the meantime which is hardly compatible with the frequent profile changes of the course.

Le but de la présente invention est de remédier à ces inconvénients.The object of the present invention is to remedy these drawbacks.

A cet effet, elle a pour objet un dispositif du type précité, comprenant des moyens de commande, les uns assurant l'actionnement des griffes, les autres contrôlant l'ampleur de cet actionnement, notamment caractérisé en ce qu'au moins l'un de ces moyens de ccmmande est relié à l'arbre de pivotement des griffes par l'intermédiaire de moyens de réglage de son action sur les griffes.To this end, it relates to a device of the aforementioned type, comprising control means, some ensuring the actuation of the claws, the others controlling the extent of this actuation, in particular characterized in that at least one of these control means is connected to the pivot shaft of the claws by means of means for adjusting its action on the claws.

Grâce à ce dispositif, l'intensité du freinage du ski lors de son avance et/ou de son déplacement vers l'arriére peut être réglée dans une large plage de valeur voire même être annulée. L'invention sera bien comprise à l'aide de la description ci-après faite, à titre d'exemple non limitatif, en regard du dessin ci-annexé représentant schématiquement :

  • - figure 1 : le dispositif vu en perspective, certains organes étant séparés pour plus de clarté,
  • - figure 2 : ce dispositif vu de dessus,
  • - figure 3 : une coupe selon C-C de la figure 2,
  • - figures 4a et 4b : vu de profil, un ski équipé du dispositif et utilisé respectivement en montée (figure 4a) et en descente (4b),
  • - figure 5 : vue en perspective, une variante de réalisation du dispositif,
  • - figure 6 : à plus grande échelle, un détail du dispositif. Le dispositif comprend un support ou chassis 1 constitué par- deux parois latérales 2, rigidement reliées par une plaque frontale soudée 3, une entretoise avant 5 et une entretoise arrière 4.
Thanks to this device, the braking intensity of the ski during its advance and / or its movement towards the rear can be adjusted within a wide range of values or even be canceled. The invention will be clearly understood with the aid of the description below, given by way of nonlimiting example, with reference to the appended drawing schematically representing:
  • - Figure 1: the device seen in perspective, certain members being separated for clarity,
  • - Figure 2: this device seen from above,
  • FIG. 3: a section along CC of FIG. 2,
  • - Figures 4a and 4b: seen in profile, a ski equipped with the device and used respectively uphill (Figure 4a) and downhill (4b),
  • FIG. 5: perspective view, an alternative embodiment of the device,
  • - Figure 6: on a larger scale, a detail of the device. The device comprises a support or chassis 1 consisting of two side walls 2, rigidly connected by a welded front plate 3, a front spacer 5 and a rear spacer 4.

Le support 1 est susceptible d'être monté sur le ski directement ou de préférence grâce à une plaque basale 11 assurant son amovibilité rapide et présentant par exemple une partie frontale 6 et un bord arrière recourbé 7, ainsi que des trous 8 permettant son vissage sur le ski.The support 1 is capable of being mounted on the ski directly or preferably by means of a basal plate 11 ensuring its rapid removable and having for example a front part 6 and a curved rear edge 7, as well as holes 8 allowing it to be screwed onto ski.

L'entretoise 4 du support, qui comporte par exemple des portions en saillie 4a, est destinée à être engagée dans le bord arrière recourbé 7 de la plaque basale 11, tandis que la plaque frontale 3-du support s'applique sur la partie frontale 6 de la plaque basale 11 sur laquelle elle est fixée de façon amovible grâce par exemple à un écrou à oreilles 9 et une vis 10.The spacer 4 of the support, which comprises for example protruding portions 4a, is intended to be engaged in the curved rear edge 7 of the base plate 11, while the front plate 3-of the support is applied to the front part 6 of the basal plate 11 on which it is removably fixed thanks for example to a wing nut 9 and a screw 10.

Le support porte un arbre de pivotement 12 qui, par exemple, traverse les deux parois latérales 2. Il porte à au moins l'une de ses extrémités une griffe d'ancrage 13, 14.The support carries a pivot shaft 12 which, for example, crosses the two side walls 2. It carries at at least one of its ends an anchoring claw 13, 14.

Ces griffes 13, 14 et l'arbre de pivotement réalisent une pièce en forme de "U" ou de "L" constituant l'organe de retenue coopérant avec la neige.These claws 13, 14 and the pivot shaft produce a part in the shape of a "U" or "L" constituting the retaining member cooperating with the snow.

De préférence, ces griffes ont une section transversale en "L"' et comportent donc chacune deux ailes 15 et 16 ou 17 et 18 perpendiculaires entre elles, l'une 15, 17 dite de freinage, étant située dans un plan comprenant l'axe de l'arbre de pivotement 12 ou sensiblement parallèle à celui-ci, l'autre 16, 18 dite verticale, étant située dans un plan par rapport auquel l'axe de cet arbre 12 est perpendiculaire, cette aile verticale étant destinée à donner au ski une bonne stabilité latérale. Afin de ne pas se heurter lors de leurs mouvements relatifs, les griffes 14 destinées à être montées du côté intérieur des skis peuvent comporter une surface de freinage 17 moins large que celle des griffes extérieures 13.Preferably, these claws have a cross section in "L" 'and therefore each have two wings 15 and 16 or 17 and 18 perpendicular to each other, one 15, 17 called braking, being located in a plane comprising the axis of the pivoting shaft 12 or substantially parallel thereto, the other 16, 18 known as vertical, being situated in a plane with respect to which the axis of this shaft 12 is perpendicular, this vertical wing being intended to give the ski good lateral stability. In order not to collide during their relative movements, the claws 14 intended to be mounted on the interior side of the skis may have a braking surface 17 that is narrower than that of the outer claws 13.

Les deux griffes 13, 14 peuvent présenter à leurs extrémités, une denture 19 facilitant la pénétration dans la neige et permettant l'accrochge sur la glace.The two claws 13, 14 may have at their ends, a toothing 19 facilitating penetration in the snow and allowing the attachment to the ice.

Il est à remarquer que l'on peut utiliser des griffes de longueurs différentes et, par exemple, plus longues pour la neige poudreuse profonde que pour une utilisation sur une surface glacée.It should be noted that it is possible to use claws of different lengths and, for example, longer for deep powder snow than for use on an icy surface.

Pour ce faire, on peut changer les griff-es ou prévoir un réglage de leur longueur.To do this, you can change the claws or provide an adjustment of their length.

Pour changer de griffes, il suffit d'adapter un autre support sur la plaque basale ou de démonter et de remonter les griffes des extrémités de l'arbre 12 où, à cet effet, les griffes sont fixées par exemple par un écrou de serraqe 20.To change claws, simply adapt another support on the basal plate or disassemble and reassemble the claws of the ends of the shaft 12 where, for this purpose, the claws are fixed for example by a nut of tightening q e 20.

Pour le réglage, au lieu d'un simple perçage, on peut réaliser le passage de l'arbre 12 au travers de l'aile verticale 16, 18 de chaque griffe 13, 14 sous la forme d'une lumière longitudinale 52 et il suffit alors de desserrer les écrous 20 pour pouvoir amener les dites griffes 13, 14 à la longueur souhaitée.For the adjustment, instead of a simple drilling, the shaft 12 can pass through the vertical wing 16, 18 of each claw 13, 14 in the form of a longitudinal light 52 and it suffices then loosen the nuts 20 to be able to bring said claws 13, 14 to the desired length.

Le dispositif comprend en outre des moyens de commande 21, 24, les uns 21 assurant l'actionnement des griffes 13, 14, les autres 24 contrôlant l'ampleur de cet actionnement.The device further comprises control means 21, 24, some 21 ensuring the actuation of the claws 13, 14, the others 24 controlling the extent of this actuation.

Au moins l'un de ces moyens de commande 21, 24 est relié à l'arbre de pivotement 12 par l'intermédiaire de moyens 23 de réglage de son action sur les griffes.At least one of these control means 21, 24 is connected to the pivot shaft 12 by means 23 for adjusting its action on the claws.

Le moyen d'actionnement 21 consiste de préférence en un contrepoids 30 relié à l'arbre de pivotement 12 pour former avec les griffes 13, 14 un balancier 25 sensible à l'inclinaison de l'axe longitudinal du ski 22.The actuating means 21 preferably consists of a counterweight 30 connected to the pivot shaft 12 to form with the claws 13, 14 a balance 25 sensitive to the inclination of the longitudinal axis of the ski 22.

Le moyen de réglage 23 susceptible d'être interposé entre le contrepoids 30 et les griffes comprend, par exemple, une tige 26 associée à l'arbre 12, et sur laquelle, par l'une de ses extrémités, est articulée autour d'un axe 28 une seconde tige 27 dont l'autre extrémité porte le contrepoids 30.The adjustment means 23 capable of being interposed between the counterweight 30 and the claws comprises, for example, a rod 26 associated with the shaft 12, and on which, by one of its ends, is articulated around a axis 28 a second rod 27, the other end of which carries the counterweight 30.

L'axe 28 sera par exemple constitué par la tige d'un ensemble vis 28 et écrou 29.The axis 28 will for example consist of the rod of a screw 28 and nut 29 assembly.

C'est bien entendu, cette articulation 28 qui permet de régler l'action du contrepoids 30 pour commander le basculement lors d'une inclinaison plus ou moins importante du ski.It is of course, this articulation 28 which makes it possible to adjust the action of the counterweight 30 to control the tilting during a more or less significant inclination of the ski.

Dans une variante de réalisation, le moyen de réglage 23 susceptible d'être interposé entre le contrepoids 30 et 1es_ griffes ne comprend qu'une tige 26 portant directement à l'une de ses extrémités 38 le contrepoids 30 mais, alors au moins dans ce cas, la griffe ou l'autre extrémité de la tige est associée à l'arbre 12 par l'intermédiaire d'une bague 39 pourvue de moyens 40 à 43 tant d'immobilisation par rapport à l'arbre 12 que de réglage en orientation autour de l'axe de cet arbre 12.In an alternative embodiment, the adjustment means 23 capable of being interposed between the counterweight 30 and 1es_ claws comprises only a rod 26 carrying directly at one of its ends 38 the counterweight 30 but, then at least in this case, the claw or the other end of the rod is associated with the shaft 12 by means of a ring 39 provided with means 40 to 43 both immobilized with respect to the shaft 12 and with adjustment in orientation around the axis of this tree 12.

Dans un mode préféré de réalisation, ces moyens consistent en des cannelures complémentaires 42 exécutées dans l'alésage 40 de la bague et sur une portée 41 de l'arbre 12.In a preferred embodiment, these means consist of complementary grooves 42 executed in the bore 40 of the ring and on a bearing surface 41 of the shaft 12.

Pour changer la position de la bague, il suffit alors de dégager latéralement la bague 39 de sa portée cannelée 41 pour la libérer en rotation puis de la réengager en bonne orientation sur la portée cannelée 41.To change the position of the ring, it suffices to disengage the ring 39 laterally from its grooved bearing 41 to release it in rotation then to re-engage it in the correct orientation on the grooved bearing 41.

Dans un autre mode de réalisation, l'alésage de la bague 39 et la portée 41 de l'arbre 12 sont cylindriques mais s la a bague comprend un organe 43 de blocage sur l'arbre tel une vis de pression 43 traversant radialement la bague 39.In another embodiment, the bore of the ring 39 and the bearing 41 of the shaft 12 are cylindrical but if the ring comprises a member 43 for locking on the shaft such as a pressure screw 43 passing radially through the ring 39.

Dans un mode préféré de réalisation, la bague est interposée entre la tige 26 et l'arbre 12 et 1a vis de pression 43 est avantageusement constituée par l'extrémité filetée 37 de la tige 26 portant le contrepoids.In a preferred embodiment, the ring is interposed between the rod 26 and the shaft 12 and the pressure screw 43 is advantageously constituted by the threaded end 37 of the rod 26 carrying the counterweight.

Comme dans les dispositifs connus, des butées déterminent les positions dites extrêmes des griffes, positions extrêmes dans lesquelles elles sont orientées soit sensiblement parallèlement aux skis 22 (figure 4b) et donc inactives, soit sensiblement perpendiculairement aux skis et offrent alors une coopération optimale avec la neige (figure 4a).As in the known devices, stops determine the so-called extreme positions of the claws, extreme positions in which they are oriented either substantially parallel to the skis 22 (FIG. 4b) and therefore inactive, or substantially perpendicular to the skis and then offer optimal cooperation with the snow (Figure 4a).

Comme dans les dispositifs connus, les butées extrêmes peuvent coopérer directement avec les griffes.As in the known devices, the extreme stops can cooperate directly with the claws.

Par exemple, ces butées sont constituées par les extrémités d'au moins une entretoise 32, 33 portée par le support dont elle traverse les parois latérales.For example, these stops are formed by the ends of at least one spacer 32, 33 carried by the support from which it passes through the side walls.

De même manière, les moyens 24 contrôlant l'amplitude de l'actionnement des griffes, et qui, à cet effet, définissent les limites plus étroites du mouvement à l'intérieur de ces maxima, qui sont choisis par exemple, soit pour interdir le retour en position totalement inactive, soit pour limiter la sortie des griffes vers leur position active, soit les deux à la fois, peuvent consister en au moins une butée portée par le support de manière à coopérer directement avec les griffes.Similarly, the means 24 controlling the amplitude of the actuation of the claws, and which, for this purpose, define the narrower limits of movement within these maxima, which are chosen for example, either to prohibit the return to the fully inactive position, either to limit the output of the claws to their active position, or both at the same time, may consist of at least one stop carried by the support so as to cooperate directly with the claws.

Dans un autre mode de réalisation, les butées extrêmes et/ou les moyens 24 contrôlant l'amplitude de l'actionnement des griffes coopèrent avec au moins une butée 26 associée à l'arbre de pivotement 12.In another embodiment, the extreme stops and / or the means 24 controlling the amplitude of the actuation of the claws cooperate with at least one stop 26 associated with the pivot shaft 12.

Avantageusement, la butée 26 est associée à l'arbre 12 par une bague 39 qui est, tant immobilisée par rapport à l'arbre, que réglable en orientation autour de cet arbre 12.Advantageously, the stop 26 is associated with the shaft 12 by a ring 39 which is both immobilized relative to the shaft and adjustable in orientation around this shaft 12.

De préférence, cette bague 39 est constituée par celle portant le contrepoids et/ou la butée 26 est constituée par la tige 26 associée à cette bague pour porter le contrepoids 30 et bénéficie donc des mêmes moyens de réglage 23 que ce moyen de commande.Preferably, this ring 39 is constituted by that carrying the counterweight and / or the stop 26 is constituted by the rod 26 associated with this ring for carrying the counterweight 30 and therefore benefits from the same adjustment means 23 as this control means.

La butée 26 qui est mobile, coopère alors avec au moins une butée fixe 47, 48 portée par le support.The stop 26 which is movable, then cooperates with at least one fixed stop 47, 48 carried by the support.

On peut alors interdir totalement aux griffes 13, 14 de quitter l'une des positions extrêmes pour obtenir soit aucune action de freinage, soit une action permanente.We can then totally prohibit the claws 13, 14 from leaving one of the extreme positions to obtain either no braking action, or a permanent action.

Dans un autre mode de réalisation, les butées fixes 47, 48 sont constituées par des tiges ou goupilles trouvant place dans l'un des orifices 46 exécutés à cet effet dans au moins une paroi 45 telle au moins une des parois latérales du support ou un secteur semi-circulaire sensiblement centré sur l'axe de rotation de l'arbre 12 et orienté dans un plan parallèle au plan de débattement de la butée mobile 26.In another embodiment, the fixed stops 47, 48 are constituted by rods or pins located in one of the orifices 46 made for this purpose in at least one wall 45 such as at least one of the side walls of the support or a semi-circular sector substantially centered on the axis of rotation of the shaft 12 and oriented in a plane parallel to the plane of movement of the movable stop 26.

Dans une variante de réalisation, les butées fixes 47, 48 sont constituées par les extrémités d'une lumière exécutée dans une pièce 35 solidaire du support et orientée dans un plan parallèle au plan de débattement de la butée mobile qui y est engagée. Dans le cas où le moyen d'actionnement 41 consiste en un élément- élastique, celui-ci est de préférence associé à une bague 39 du type précité, et ce, bien entendu en un point situé en dehors de l'axe de l'arbre de pivotement 12.In an alternative embodiment, the fixed stops 47, 48 are formed by the ends of a light executed in a part 35 secured to the support and oriented in a plane parallel to the plane of movement of the movable stop which is engaged therein. In the case where the actuating means 41 consists of an elastic element, this is preferably associated with a ring 39 of the aforementioned type, and this, of course at a point situated outside the axis of the pivot shaft 12.

De manière connue, il sollicite les griffes vers leur positon active.In a known manner, it requests the claws towards their active position.

Par cela, la réaction du dispositif de l'invention est immédiate et lors de la montée, le léger recul du ski est supprimé. Le dispositif est muni d'un couvercle frontale 35, par exemple en matière plastique, s'engageant à friction sur la partie frontale du support 1.By this, the reaction of the device of the invention is immediate and during the climb, the slight decline of the ski is eliminated. The device is provided with a front cover 35, for example made of plastic, engaging in friction on the front part of the support 1.

Ce couvercle 35 empêche la neige_de pénétrer à l'intérieur du support afin que la pièce basculante ne soit pas gênée dans son mouvement.This cover 35 prevents snow from entering the interior of the support so that the tilting part is not hampered in its movement.

Le dispositif est monté de préférence immédiatement devant la fixation des chaussures 36 sur le ski 22 tel qu'illustré à la figure 4.The device is preferably mounted immediately before the binding of the boots 36 on the ski 22 as illustrated in FIG. 4.
