Description

Le brevet français n° 87 07099 est relatif à un dispositif composé d'un volet articulé sur un axe transversal porté par un tenon solidaire du ski, de deux bras latéraux coudés et contrecoudés dont les extrémités antérieures en forme de tourillon sont montées en rotation dans les alésages du volet autour d'un axe disposé dans un plan longitudinal, de moyens de calage en position inactive des bras sur le ski et, de moyens amenant les bras de la position inactive à une position active dans laquelle ils s'étendent latéralement au ski.French Patent No. 87,07099 relates to a device composed of a flap articulated on a transverse axis carried by a stud secured to the ski, two bent and counter-bent side arms whose anterior ends in the form of a trunnion are mounted for rotation in the bores of the flap around an axis arranged in a longitudinal plane, of means for wedging in the inactive position of the arms on the ski and, of means bringing the arms from the inactive position to an active position in which they extend laterally ski.

En position inactive, le dispositif est verrouillé avec ses bras disposés au dessus du ski et en direction de l'arrière de celui-ci. Pour l'amener en position active, il suffit d'actionner les moyens de calage du dispositif de manière à libérer ces bras qui, dans un premier temps, pivotent latéralement de part et d'autre du ski par rapport au volet, puis, dans un second temps, pivotent en même temps que le volet de manière que l'extrémité de leur partie postérieure constituant crampon vienne en contact avec la neige ou la glace sous-jacente. De la sorte, lorsque l'utilisateur prend appui sur l'un des skis pour avancer l'autre ski en vue de gravir une pente, le dispositif anti recul en appui reçoit toute la réaction de l'effet d'avancement de l'autre ski et pivote par rapport au ski jusqu'à ce que les parties intermédiaires des bras latéraux viennent en contact avec le ski et transmettent à ce dernier une partie de l'effort résistant qui, sans cela, risquerait de détériorer le dispositif ou son mécanisme d'articulation.In the inactive position, the device is locked with its arms arranged above the ski and towards the rear of the ski. To bring it into the active position, it suffices to actuate the wedging means of the device so as to release these arms which, at first, pivot laterally on either side of the ski relative to the flap, then, in a second time, pivot at the same time as the flap so that the end of their rear part constituting a crampon comes into contact with the snow or the underlying ice. In this way, when the user presses on one of the skis to advance the other ski in order to climb a slope, the anti-recoil device in support receives all the reaction of the advancement effect of the other ski and pivots with respect to the ski until the intermediate parts of the lateral arms come into contact with the ski and transmit to it a part of the resistant force which, otherwise, would risk damaging the device or its mechanism. 'joint.

Ce dispositif donne entière satisfaction et permet au skieur de monter des pentes plus fortes que ne le permettaient les peaux de phoques ou tous autres moyens équivalents. Toutefois, les moyens de rappel des bras décrits dans les deux formes d'exécution de ce brevetse révèlent complexes et onéreux en raison des nombreuses pièces les composant.This device is entirely satisfactory and allows skiers to climb steeper slopes than allowed by seal skins or any other equivalent means. However, the means for returning the arms described in the two embodiments of this patent reveal to be complex and expensive because of the numerous parts making them up.

La présente invention fournit une nouvelle forme d'exécution permettant d'obtenir des résultats supérieurs avec une structure plus simple et moins onéreuse, tant au niveau du nombre de pièces que du montage.The present invention provides a new embodiment making it possible to obtain superior results with a simpler and less expensive structure, both in terms of the number of parts and of the assembly.

A cet effet, les moyens amenant les bras de leur position inactive à leur position active sont constitués, d'une part, par une bascule de commande qui, pouvant pivoter entre deux positions respectivement avant et arrière autour d'un axe transversal horizontal disposé en avant de l'axe du volet, est solidaire d'un poussoir élastique dont l'extrémité libre crantée est apte, lorsque la bascule est amenée en position arrière, à coiffer un bec transversal saillant de l'extrémité antérieure du volet et à faire pivoter ce volet dans le sens du relevage des bras par rapport à un berceau de calage sur le ski, et d'autre part, par des moyens à ressort d'écartement des bras en position active.To this end, the means bringing the arms from their position inactive in their active position consist, on the one hand, of a control lever which, being able to pivot between two positions respectively front and rear around a horizontal transverse axis disposed in front of the axis of the flap, is integral with an elastic pusher, the notched free end of which is capable, when the lever is brought into the rear position, to cover a projecting transverse spout from the anterior end of the flap and to pivot this flap in the direction of raising the arms relative to a cradle for wedging on the ski, and on the other hand, by spring means for spreading the arms in the active position.

Grâce à cet agencement, et selon la position en avant ou en arrière donnée à la bascule, les bras peuvent être amenés de leur position neutre de transport, au repos dans le berceau, à leur position d'écartement, puis, par basculement en sens inverse de la bascule, à leur position de fonctionnement anti-recul.Thanks to this arrangement, and according to the position forward or backward given to the rocker, the arms can be brought from their neutral transport position, at rest in the cradle, to their spacing position, then, by tilting in the direction reverse of the rocker, to their anti-recoil operating position.

Avantageusement, le poussoir a une largeur inférieure à l'intervalle entre les deux têtes des tourillons afin, lorsque les bras sont en position active et que la bascule est ramenée en position arrière, de venir devant le bec du volet pour former organe de maintien élastique des bras constituant alors freins de descentAdvantageously, the pusher has a width less than the interval between the two heads of the pins so that, when the arms are in the active position and the rocker is returned to the rear position, come in front of the flap spout to form an elastic holding member arms then constituting descent brakes

Ainsi, le dispositif anti-recul, permettant au skieur de gravir des pentes en se passant de peaux de phoques, peut aussi être utilisé également comme frein de descente.Thus, the anti-recoil device, allowing skiers to climb slopes without skins of seals, can also be used as a descent brake.

Ce dispositif comprend deux bras latéraux 2 montés pivotant par leur tourillon 7 dans un volet 3 articulé sur un axe transversal 9 porté par un tenon 10. Les tourillons 7 ont leurs axes longitudinaux x′-x qui sont parallèles au plan médian longitudinal du ski 5 sur lequel est monté le dispositif. Le tenon 10 est solidaire d'une semelle de fixation 4 liée au ski 5. Le volet 3 est constitué par une pièce en forme de "U" dont chacune des ailes latérales 3a est munie d'un palier pour le tourillon 7 et est traversée par un alésage transversal, non représenté, recevant l'axe d'articulation 9. Chaque tourillon 7 est relié par une partie intermédiaire 15 coudée par rapport à lui, à une partie postérieure 16 contrecoudée formant palette et dont l'extrémitéest munie d'un bec 17.This device comprises two lateral arms 2 pivotally mounted by their pin 7 in a flap 3 articulated on a transverse axis 9 carried by a pin 10. The pins 7 have their longitudinal axes x′-x which are parallel to the longitudinal median plane of the ski 5 on which the device is mounted. The tenon 10 is integral with a fixing sole 4 linked to the ski 5. The flap 3 is constituted by a part in the shape of a "U", each of the lateral wings 3a of which is provided with a bearing for the journal 7 and is traversed by a transverse bore, not shown, receiving the hinge pin 9. Each pin 7 is connected by an intermediate part 15 bent with respect to it, to a rear part 16 bent back forming a pallet and the end of which is provided with a spout 17.

Comme montré à la figure 2, chacun des bras 2 est recouvert, au-delà de sa partie constituant tourillon 7, par une gaine 51, surmoulée en forme sur lui de manière à lui donner, au moins sur la partie postérieure 16, une forme de palette.As shown in Figure 2, each of the arms 2 is covered, beyond its part constituting the pin 7, by a sheath 51, molded in shape on it so as to give it, at least on the rear part 16, a shape palette.

Selon l'invention, les moyens amenant les bras de leur position active à leur position inactive sont constitués, d'une part, par une bascule de commande 52, articulée autour d'un axe transversal horizontal 53 disposé en avant de l'axe 9 et, d'autre part, par des moyens de rappel 54 reliant des têtes 55 fixées à l'extrémité des tourillons 7.According to the invention, the means bringing the arms from their active position to their inactive position consist, on the one hand, of a control rocker 52, articulated around a horizontal transverse axis 53 disposed in front of the axis 9 and, on the other hand, by return means 54 connecting heads 55 fixed to the end of the pins 7.

Comme le montre les figures, la bascule 52 est réalisée en matière synthétique moulée et présente la forme d'un segment de couronne 52a relié par des bras 52b à un moyeu 52c. Cette bascule oscille à travers une ouverture 56 ménagée entre une paroi transversale 57 de la semelle 4 et un capot 58 rapporté sur cette semelle. A sa partie supérieure, elle comporte une face d'appui 59 rainurée ou crantée permettant de l'actionner manuellement ou avec l'extrémité d'une canne de ski. Cette bascule est solidaire d'un poussoir 60 et d'un levier radial 62. Le poussoir 60 est lié à elle par une zone amincie 63 constituant charnière élastique. Quant au levier 62, il coopère avec des moyens 64 assurant le verrouillage élastique de la bascule dans chacune de ses deux positions, à savoir, sa position avant représentée à la figure 1 et sa position arrière représentée à la figure 2.As shown in the figures, the rocker 52 is made of molded synthetic material and has the shape of a ring segment 52a connected by arms 52b to a hub 52c. This rocker oscillates through an opening 56 formed between a transverse wall 57 of the sole 4 and a cover 58 attached to this sole. At its upper part, it has a grooved or notched support face 59 enabling it to be actuated manually or with the end of a ski pole. This lever is integral with a pusher 60 and a radial lever 62. The pusher 60 is linked to it by a thinned zone 63 constituting an elastic hinge. As for the lever 62, it cooperates with means 64 ensuring the elastic locking of the lever in each of its two positions, namely, its front position shown in FIG. 1 and its rear position shown in FIG. 2.

Dans la forme d'exécution représentée, ces moyens de verrouillage sont constitués par un ressort fixe, en forme de lyre, présentant en vis à vis du levier radial 62 deux crans 65 séparés par une ondulation déformable élastiquement 66. Ce ressort est réalisé en matière synthétique ou en fil d'acier.In the embodiment shown, these locking means are constituted by a fixed spring, in the form of a lyre, having opposite the radial lever 62 two notches 65 separated by an elastically deformable corrugation 66. This spring is made of material synthetic or steel wire.

A son extrémité libre, le poussoir 60 est muni d'un cran 67 destiné à coopérer avec un bec 68 formé à l'extrémité antérieure du volet 3.At its free end, the pusher 60 is provided with a notch 67 intended to cooperate with a spout 68 formed at the front end of the flap 3.

Enfin, le prolongement 4a de la semelle 4 est muni d'un berceau 69 comportant des crans de positionnement des bras 2 lorsqu'ils sont dans la position neutre de transport, représentée à la figure 1.Finally, the extension 4a of the sole 4 is provided with a cradle 69 comprising notches for positioning the arms 2 when they are in the neutral transport position, shown in FIG. 1.

Comme montré plus en détails à la figure 2, chacune des têtes 55 des tourillons 7 est munie de moyens 70, tel qu'un pion engagé dans un alésage de la tête, permettant l'accrochage de l'une des extrémités d'un ressort transversal 54, commun aux deux têtes et rappelant en permanence les bras 2 en position active, c'est à dire en position écartée de part et d'autre du ski 5.As shown in more detail in Figure 2, each of the heads 55 of the pins 7 is provided with means 70, such as a pin engaged in a bore of the head, allowing the attachment of one of the ends of a spring transverse 54, common to the two heads and permanently recalling the arms 2 in the active position, that is to say in the separated position on either side of the ski 5.

Pour amener le dispositif de sa position neutre de transport à sa position active, il faut, dans un premier temps, faire pivoter la bascule 52 dans le sens de la flèche 73 de figure 1 pour l'amener de sa position en avant, représentée à cette figure, à sa position en arrière, représentée à la figure 2. Durant ce pivotement, le cran 67 du poussoir 60 vient coiffer le bec 68 du volet 3 et provoque le pivotement de ce volet 3 et des bras 2 dans le sens de la flèche 74 de figure 2. Sous l'effet de ce pivotement, les extrémités postérieures des bras 2 échappent des crans du berceau 69 et sous l'action du ressort 54, pivotent autour de leur tourillon 7 en amenant leur partie en forme de palette 16 de part et d'autre du ski 5, comme montré à la figure 2.To bring the device from its neutral transport position to its active position, it is first necessary to pivot the rocker 52 in the direction of the arrow 73 in FIG. 1 to bring it from its forward position, shown at this figure, in its rear position, represented in FIG. 2. During this pivoting, the notch 67 of the pusher 60 comes to cover the spout 68 of the flap 3 and causes the pivoting of this flap 3 and of the arms 2 in the direction of the arrow 74 in Figure 2. Under the effect of this pivoting, the rear ends of the arms 2 escape from the notches of the cradle 69 and under the action of the spring 54, pivot around their pin 7 by bringing their part in the form of a pallet 16 on either side of ski 5, as shown in FIG. 2.

Il faut noter que dans cette position, les bras 2 sont en position anti-recul mais ne peuvent pas assurer cette fonction puisqu'ils sont immobilisés par le poussoir 60 s'opposant à l'élévation du volet 3. Pour amener ces bras dans la position anti-recul représentée à la figure 3, il faut ramener la bascule dans sa position avant en la faisant pivoter dans le sens de la flèche 75 de figure 3. Ce pivotement a pour effet d'éloigner l'extrémité crantée 67 du poussoir 60 par rapport au bec 68 du levier 3 qui peut ainsi pivoter librement dans le sens des flèches 76 en permettant le mouvement des bras 2. La figure 3 montre d'ailleurs que, comme dans le brevet principal, lorsque les bras 2 sont utilisés, ils s'appuient sur le ski 5 par leur partie intermédiaire 15 qui absorbe l'essentiel de l'effort de réaction et réduit donc l'effort transmis à l'axe 9 et au tenon 10 par le volet 3.It should be noted that in this position, the arms 2 are in the anti-recoil position but cannot perform this function since they are immobilized by the pusher 60 opposing the raising of the flap 3. To bring these arms into the anti-recoil position shown in Figure 3, you must return the rocker to its front position by rotating it in the direction of the arrow 75 of Figure 3. This pivoting has the effect of moving the notched end 67 of the pusher 60 relative to the spout 68 of the lever 3 which can thus pivot freely in the direction of the arrows 76 allowing the movement of the arms 2. Figure 3 also shows that, as in the main patent, when the arms 2 are used, they are supported on the ski 5 by their intermediate part 15 which absorbs most of the reaction force and therefore reduces the force transmitted to axis 9 and tenon 10 through flap 3.

Il ressort de ce qui précède que le dispositif de calage selon l'invention fait appel à un nombre de pièces réduit facilement assemblables et conduit à un prix de revient bien inférieur à celui du dispositif connu.It emerges from the above that the wedging device according to the invention uses a reduced number of easily assembled parts and leads to a cost price much lower than that of the known device.

Par ailleurs, et comme montré figure 4, ce dispositif peut être utilisé comme frein de descente, c'est à dire comme moyen de freinage des skis chaussés par le skieur.Furthermore, and as shown in FIG. 4, this device can be used as a descent brake, that is to say as a means of braking skis fitted by the skier.

A cet effet, le poussoir 60 dont la largeur est inférieure à l'intervalle entre les deux têtes 55 est amené devant le bec 68 du volet 3 et ceci par pivotement de la bascule 52 dans le sens de la flèche 77 de figure 4 alors que les bras 16 sont en position active.To this end, the pusher 60 whose width is less than the interval between the two heads 55 is brought before the spout 68 of the shutter 3 and this by pivoting of the rocker 52 in the direction of the arrow 77 of FIG. 4 while the arms 16 are in the active position.

Ainsi, lorsque les extrémités 18 des bras 16 sont soumises à des efforts tendant à les soulever vers le haut, le volet s'appuie sur le poussoir 60 qui, grâce à l'élasticité de sa charnière 60, joue le rôle d'amortisseur élastique et permet le mouvement de ces bras en fonction de la résistance qu'ils rencontrent, sans perturber le freinage qui reste régulier.Thus, when the ends 18 of the arms 16 are subjected to forces tending to lift them upwards, the flap rests on the pusher 60 which, thanks to the elasticity of its hinge 60, acts as an elastic damper and allows the movement of these arms as a function of the resistance which they meet, without disturbing the braking which remains regular.

Pour ramener les bras en position de repos, il suffit de faire pivoter la bascule 52 dans le sens de la flèche 75 de figure 3, ce qui a pour effet de désolidariser le poussoir 60 des têtes 55 et du levier 7, puis de saisir manuellement les deux bras 2 en les rapprochant l'un de l'autre par pivotement au dessus du ski à l'encontre du ressort 54 et enfin de les abaisser jusqu'à ce que leurs extrémités postérieures s'engagent dans le berceau 69.To return the arms to the rest position, it suffices to rotate the rocker 52 in the direction of the arrow 75 in FIG. 3, which has the effect of separating the pusher 60 from the heads 55 and the lever 7, then manually entering the two arms 2 by bringing them closer to one another by pivoting above the ski against the spring 54 and finally lowering them until their rear ends engage in the cradle 69.

Ce dispositif anti-recul procure ainsi des résultats supérieurs à ceux du dispositif connu.This anti-recoil device thus provides results superior to those of the known device.
