Abstract

The invention relates to a mechanical device for modifying the radial geometry of a ski, proportionally to its flexion, which includes elements, referred to as transmission elements, which, each interposed between the rod and the ski wherein each transform a relative displacement of the rod, oriented along its longitudinal axis and directed towards one of the ends of the ski (direction S1), into a second displacement oriented along a direction intersecting the longitudinal axis and directed towards the outside of the ski and wherein each apply this displacement at a selected place of the ski so as to bring about, during the relative displacement of the rod, a thrust generating the deformation of this ski along its cross-section, transverse deformation translated, in particular, through a spacing apart in the upper part of the ski and through the desired modification of the geometry of the lower face of this ski.

Description

L'invention se rapporte à un dispositif de modification de la géométrie radiale d'un ski, et ce, proportionnellement à la flexion de ce ski et de sorte qu'elle devient progressivement concave au fur et à mesure que le ski est sollicité en flexion au cours de son utilisation.The invention relates to a device for modifying the radial geometry of a ski, and this, in proportion to the flexion of this ski and so that it gradually becomes concave as the ski is bending during its use.

L'invention se rapporte également à un ski équipé de ce dispositif.The invention also relates to a ski equipped with this device.

Le dispositif fonctionne quel que soit la technique de construction composite du ski ("sandwich", monocoque ou autre).The device works regardless of the construction technique composite of the ski ("sandwich", monocoque or other).

Par le terme ski, on désigne toute lame utilisée pour prendre appui et glisser sur la neige, c'est-à-dire effectivement un ski en tant que tel, mais également un monoski, une planche des neiges ou autre.By the term ski, is meant any blade used to support and slide on the snow, that is to say actually a ski as such, but also a monoski, a snowboard or other.

Par dispositif mécanique de modification de la géométrie radiale d'un ski, proportionnellement à sa flexion, on désigne un dispositif exploitant le déplacement relatif d'au moins une tige orientée sensiblement longitudinalement au ski pour, en une zone choisie de ce ski, provoquer une déformation du ski selon sa section transversale et entraíner la modification recherchée de la géométrie de sa face inférieure.By mechanical device for modifying the radial geometry of a ski, in proportion to its flexion, designates a device exploiting the relative displacement of at least one rod oriented substantially longitudinally to the ski for, in a chosen zone of this ski, to provoke a deformation of the ski according to its cross section and cause the modification searched for the geometry of its lower face.

On connaít par exemple le document EP-A-1297869 qui propose un dispositif pour modifier la géométrie radiale d'un ski en fonction de la flexion de ce ski.We know for example the document EP-A-1297869 which proposes a device for modifying the radial geometry of a ski according to the flexion of this ski.

FR-A-2794374 qui divulgue également un ski à géométrie variable est utilisé pour la forme en deux parties de la revendication indpendante.FR-A-2794374 which also discloses a ski in Variable geometry is used for the two-part form of the independent claim.

Ce dispositif est conçu pour que lors de ladite flexion du ski, la section transversale du ski devienne plus large, notamment au niveau d'une des extrémités dudit ski.This device is designed so that during said bending of the ski, the cross-section of the ski becomes wider, especially at the level of a ends of said ski.

Ce dispositif ne permet donc pas de modifier la géométrie de la face inférieure d'un ski de sorte qu'elle devient progressivement concave au fur et à mesure que le ski est sollicité en flexion au cours de son utilisation. This device does not therefore make it possible to modify the geometry of the face lower a ski so that it gradually becomes concave as and when as the ski is bent during its use.

Un dispositif qui permet d'obtenir cet effet a été décrit dans la demande internationale WO 02/40115, de la titulaire.A device which makes it possible to obtain this effect has been described in the International Application WO 02/40115, of the proprietor.

Avec ce dispositif, la géométrie radiale du ski, par exemple légèrement convexe lorsque le ski est posé à plat sur un support, devient progressivement concave, au fur et à mesure que le ski est sollicité en flexion lors de son utilisation, du fait d'un appui développé par un skieur dans la partie médiane de ce ski et des réactions d'accroche développées par le support, en avant et en arrière de cette partie médiane et notamment au niveau de la spatule et du talon du ski.With this device, the radial geometry of the ski, for example slightly convex when the ski is laid flat on a support, becomes gradually concave, as the ski is flexed during its use, because of a support developed by a skier in the game median of this ski and the grip reactions developed by the support, forward and backward of this middle part and especially at the level of the spatula and heel of the ski.

Cette modification ou adaptation de la géométrie radiale du ski en fonction des sollicitations de flexion permet d'améliorer le comportement général du ski ainsi que son rendement.This modification or adaptation of the radial geometry of the ski in bending stress function helps improve behavior skiing and its performance.

Avec un tel dispositif, le déclenchement et la tenue du ski en courbe sont facilités.With such a device, the triggering and holding of the ski curve are facilitated.

La présence de ce dispositif sur un ski dit "de carve", permet d'accentuer l'effet "carving" du ski.The presence of this device on a ski called "carve", allows to accentuate the "carving" effect of the ski.

La présence du dit dispositif sur un ski permet également d'atténuer les vibrations de ce ski.The presence of said device on a ski also serves to mitigate the vibrations of this ski.

De par les possibilités de réglages qu'il autorise, le dispositif permet d'adapter le ski à la qualité de la neige et/ou aux exigences de l'utilisateur.Thanks to the adjustment possibilities it allows, the device allows to adapt the ski to the quality of the snow and / or the requirements of the user.

Un résultat que l'invention vise à obtenir est un dispositif du type précité qui permet de maítriser parfaitement la dimension longitudinale de chaque partie du ski dans laquelle la géométrie radiale doit être modifiée.A result that the invention aims to obtain is a device of the type mentioned above, which makes it possible to perfectly control the longitudinal dimension of each part of the ski in which the radial geometry must be modified.

Un autre résultat que l'invention vise à obtenir est un dispositif du type précité qui, après suppression d'une contrainte de flexion ayant engendré une modification de la géométrie radiale du ski, garantit le rétablissement de la géométrie radiale à son état initial. Another result that the invention seeks to obtain is a device of the aforementioned type which, after removal of a bending stress having caused a modification of the radial geometry of the ski, guarantees the restoration of the radial geometry in its initial state.

A cet effet, l'invention a pour objet un dispositif du type précité, notamment, caractérisé en ce qu'il comprend des éléments, dit éléments de transmission qui, interposés chacun entre la tige et le ski :

  • transforment chacun un déplacement relatif de la tige, orienté selon son axe longitudinal et dirigé vers l'une des extrémités du ski (sens S1), en un second déplacement orienté selon une direction sécante audit axe longitudinal et dirigé vers l'extérieur du ski,
  • appliquent chacun ce déplacement en un endroit choisi du ski, de manière à, lors dudit déplacement relatif de la tige, provoquer une action de poussée engendrant la déformation de ce ski selon sa section transversale, déformation transversale traduite, notamment, par un écartement dans la partie supérieure du ski et, par la modification recherchée de la géométrie de la face inférieure de ce ski.
For this purpose, the subject of the invention is a device of the aforementioned type, characterized in that it comprises elements, said transmission elements which interpose each between the rod and the ski:
  • each transform a relative displacement of the rod, oriented along its longitudinal axis and directed towards one end of the ski (direction S1), in a second displacement oriented in a direction intersecting said longitudinal axis and directed towards the outside of the ski,
  • each apply this displacement in a chosen location of the ski, so that, during said relative displacement of the rod, cause a thrust action causing the deformation of the ski according to its cross section, transverse deformation translated, in particular, by a gap in the upper part of the ski and, by the desired modification of the geometry of the lower face of this ski.

L'invention a également pour objet un ski équipé de ce dispositif.The invention also relates to a ski equipped with this device.

L'invention sera mieux comprise à la lecture de la description ci-après faite en regard du dessin ci-annexé qui représente schématiquement :

  • figure 1 : une vue de dessus d'un ski équipé d'un dispositif selon l'invention, suivant une première forme de réalisation,
  • figure 2 : à plus grande échelle, une vue partielle et de dessus du ski de la figure 1, sensiblement au niveau de la spatule,

  • figure 4 : une vue de coupe transversale de la spatule de la figure 2, après modification de la section transversale de cette spatule,
  • figure 5 : une vue partielle de dessus de la spatule d'un ski équipé d'un dispositif selon l'invention suivant une seconde forme de réalisation.
The invention will be better understood on reading the following description made with reference to the attached drawing which schematically shows:
  • FIG. 1 is a plan view of a ski equipped with a device according to the invention, according to a first embodiment,
  • FIG. 2: on a larger scale, a partial view from above of the ski of FIG. 1, substantially at the level of the spatula,
  • FIG. 3: a cross-sectional view of the ski of FIG. 2, before modification of the transverse section of this spatula,
  • FIG. 4: a cross-sectional view of the spatula of FIG. 2, after modification of the cross-section of this spatula,
  • FIG. 5 is a partial view from above of the spatula of a ski equipped with a device according to the invention according to a second embodiment.

En se reportant au dessin, on voit un ski 5 équipé d'au moins un dispositif 6 de modification de sa géométrie radiale.Referring to the drawing, we see a ski 5 equipped with at least one device 6 for modifying its radial geometry.

Sur le ski 5, en figures 3 et 4, on distingue :

  • une face inférieure 50 qui permet l'appui sur un support 7, telle la neige,
  • une surface supérieure 51 opposée à la dite face inférieure 50,
  • des faces latérales 52, 53 qui, dites rives 52, 53, s'étendent chacune entre la face inférieure 50 et la surface supérieure 51 et à l'aplomb de chacune desquelles rives 52, 53 se situe, par exemple, une carre métallique 54 qui borde la face inférieure 50.
On the ski 5, in Figures 3 and 4, there are:
  • a lower face 50 which allows the support on a support 7, such as snow,
  • an upper surface 51 opposite said lower face 50,
  • lateral faces 52, 53 which, said banks 52, 53, each extend between the lower face 50 and the upper surface 51 and in line with each of which banks 52, 53 is, for example, a metal edge 54 which borders the underside 50.

Sur le ski 5, en figure 1, on distingue également :

  • deux parties extrêmes opposées 55, 56 dont, une première partie extrême 55 recourbée vers le haut, dite spatule 55 et, une seconde partie extrême 56, dite talon 56,
  • une partie médiane 57, présentant un moyen de fixation 8 d'une chaussure (non représentée).
On the ski 5, in Figure 1, there are also:
  • two opposite end portions 55, 56 of which, a first end portion 55 curved upwards, said spatula 55 and a second end portion 56, said heel 56,
  • a middle portion 57, having a fastening means 8 of a shoe (not shown).

En figure 1, le ski 5 a été dessiné transversalement dilaté de manière à autoriser une représentation schématique et comprenant, notamment, des blocs fonctionnels en tant que moyens fonctionnels.In FIG. 1, the ski 5 has been drawn transversely dilated with to allow a schematic representation and including, in particular, functional blocks as functional means.

Le dispositif de modification 6 de la géométrie radiale du ski 5 est actif essentiellement au niveau d'au moins l'une des parties extrêmes 55, 56 du ski 5 et, de préférence, des deux.The modification device 6 of the radial geometry of the ski 5 is essentially at the level of at least one of the extreme parts 55, 56 of the ski 5 and preferably both.

Le dispositif de modification 6 comprend au moins une tige 1 en matériau non compressible et cette tige 1 est orientée sensiblement longitudinalement au ski 5 et guidée en translation dans cette direction, par un moyen de guidage 4 à cet effet.The modification device 6 comprises at least one rod 1 non-compressible material and this rod 1 is oriented substantially longitudinally to the ski 5 and guided in translation in this direction, by a guiding means 4 for this purpose.

Avantageusement, mais non limitativement, la tige 1 comprend des fibres de carbone retenues dans une matrice de matériau polymère.Advantageously, but not exclusively, the rod 1 comprises carbon fibers retained in a matrix of polymeric material.

Tel que cela est représenté, la tige 1 peut être de section aplatie, mais cela n'est pas limitatif. As shown, the rod 1 may be of flattened section, but this is not limiting.

Le moyen de guidage 4 est, avantageusement, constitué par les flancs d'une rainure aménagée sous le niveau de la surface supérieure 51 du ski 5 pour loger la tige 1, et ce, sur au moins une fraction de la longueur de cette tige 1.The guiding means 4 is, advantageously, constituted by the flanks of a groove below the level of the upper surface 51 of the ski 5 to house the rod 1, and this, on at least a fraction of the length of this rod 1.

Le moyen de guidage 4 pourrait également être constitué par des pièces, en matière synthétiques ou autre, rapportées et fixées sur la surface supérieure 51 du ski 5.The guiding means 4 could also be constituted by parts, of synthetic or other material, attached and fixed on the surface upper 51 of the ski 5.

La tige 1 coopère, sensiblement au niveau de l'une 101 de ses extrémités opposées 101, 102, avec une butée d'arrêt en translation 103 associée audit ski 5 de manière telle que la flexion de ce ski 5 provoque un déplacement relatif de la tige 5 vers l'une des parties extrêmes du ski 5.The rod 1 cooperates substantially at the level of one of its 101 opposite ends 101, 102, with a translational stop 103 associated with said ski 5 so that the flexion of this ski 5 causes a relative movement of the rod 5 towards one of the extreme parts of the ski 5.

L'extrémité 101 de la tige 1 qui coopère avec la butée d'arrêt en translation 103 est dite extrémité passive 101 et, l'extrémité 102 opposée de la tige 1 est dite extrémité active 102.The end 101 of the rod 1 which cooperates with the stopper in translation 103 is said passive end 101 and the opposite end 102 of the rod 1 is said active end 102.

De préférence, chaque butée d'arrêt en translation 103 se situe dans la zone du moyen de fixation 8 d'une chaussure (non représentée) sur le ski 5.Preferably, each stop stop in translation 103 is located in the zone of the attachment means 8 of a boot (not shown) on the ski 5.

Lors de la flexion du ski 5, la tige 1 fléchit également.During the flexion of the ski 5, the rod 1 also flexes.

Pour que cette double flexion puisse être obtenue, il faut que la tige 1 s'étende, au moins en partie, en dehors d'un plan du ski 5 qui contient la fibre dite neutre de ce ski 5.In order for this double bending to be obtained, it is necessary that the stem 1 extends, at least in part, out of a plane of the ski 5 which contains the fiber said neutral of this ski 5.

Lors de leur flexion, le ski 5 et la tige 1 se courbent selon un rayon de courbure qui leur est propre.During their bending, the ski 5 and the rod 1 bend according to a radius curvature of their own.

La différence entre les rayons de courbure du ski 5 et de la tige 1 induit un déplacement sensible de l'extrémité active 102 de la tige 1.The difference between the radii of curvature of the ski 5 and the rod 1 induces a substantial displacement of the active end 102 of the rod 1.

C'est ce déplacement relatif de la tige 1 qui est exploité pour provoquer la modification de la géométrie radiale de la partie choisie du ski 5. It is this relative displacement of the rod 1 which is exploited for cause the radial geometry of the selected part of the ski 5 to change.

Différentes solutions peuvent être utilisées pour rendre le ski 5 transversalement déformable, tant au niveau de sa spatule 55, qu'au niveau de son talon 56.Different solutions can be used to make the ski 5 transversely deformable, both at its spatula 55, and at the level of his heel 56.

Ces solutions dépendent de la structure du ski 5 et ne sont donc pas décrites en détails dans la présente demande de brevet.These solutions depend on the structure of the ski 5 and are therefore not described in detail in this patent application.

En figures 2 et 3, une solution consistant en un amincissement local de l'épaisseur du ski 5 est symbolisée.In FIGS. 2 and 3, a solution consisting of local thinning the thickness of the ski 5 is symbolized.

De manière remarquable, au lieu, comme dans le cas de la demande internationale WO 02/40115 d'exploiter le déplacement relatif de la tige 1 pour provoquer l'expansion d'une pièce qui communique sa déformation au ski 5, le dispositif de modification 6 de la géométrie radiale selon l'invention comprend au moins un élément 2, dit élément de transmission 2 qui, interposé entre la tige 1 et le ski 5 :

  • transforment chacun un déplacement relatif 100 de la tige 1, orienté selon son axe longitudinal 10 et dirigé vers l'une des extrémités du ski (sens S1), en un second déplacement 200 orienté selon une direction sécante audit axe longitudinal 10 et dirigé vers l'extérieur du ski 5,
  • appliquent chacun ce déplacement 200 en un endroit choisi du ski 5, de manière à, lors dudit déplacement relatif 100 de la tige 1, provoquer une action de poussée engendrant la déformation de ce ski 5 selon sa section transversale, déformation transversale traduite, notamment, par un écartement dans la partie supérieure du ski et, par la modification recherchée de la géométrie de la face inférieure 50 de ce ski 5. De manière remarquable, le dispositif de modification 6 comprend au moins une rangée 20 d'une pluralité d'éléments de transmission 2 espacés entre eux et orientés par rapport à la tige 1, cette rangée 20 d'éléments de transmission 2 étant située au moins d'un côté de la tige 1. Selon une première forme de réalisation (figures 1 à 4), le dispositif de modification 6 comprend au moins une tige 1 et deux rangées 20 d'éléments de transmission 2 espacés entre eux et orientés par rapport à la tige 1, ces rangées 20 étant situées de part et d'autre de la tige 1, approximativement symétriquement par rapport à l'axe longitudinal 10 de cette tige 1.Suivant une deuxième forme de réalisation (figure 5), le dispositif de modification 6 comprend au moins un ensemble 30 de deux tiges 1 qui s'étendent sensiblement parallèlement entre elles et, chacune, entre une butée d'arrêt en translation 103 fixée sur le ski 5 et la partie du ski 5 dont la géométrie radiale doit être modifiée.Conformément à une variante de la deuxième forme de réalisation, le dispositif de modification 6 comprend au moins un ensemble 30 de deux tiges 1 qui s'étendent sensiblement parallèlement à l'une des rives 52, 53 du ski 5 et, chacune, entre une butée d'arrêt en translation 103 fixée sur le ski 5 et la partie du ski 5 dont la géométrie radiale doit être modifiée.De manière remarquable, les éléments de transmission 2 de chaque rangée 20 s'étendent sensiblement parallèlement entre eux, de manière à former un angle sensiblement constant avec l'axe longitudinal 10 de la tige 1 à laquelle ils sont associés.Selon une variante, les éléments de transmission 2 de chaque rangée 20 s'étendent de manière à former avec l'axe longitudinal 10 de la tige 1 à laquelle ils sont associés, un angle qui varie d'un élément de transmission 2 à l'autre.Quoi qu'il en soit, le dispositif de modification 6 agit sur le ski 5 en une pluralité de points espacés selon la direction longitudinale dudit ski 5 et non pas de manière concentrée comme dans le cas du dispositif de la demande internationale WO 02/40115. Le respect des caractéristiques techniques précitées permet de mieux maítriser la dimension longitudinale de chaque partie du ski 5 dans laquelle la géométrie radiale doit être modifiée.Egalement, la structure et le mode de fonctionnement du dispositif de modification 6 permet au concepteur du ski 5 d'accroítre la capacité de la section transversale de se ski 5 à être déformée, sans que cela se traduise par un affaiblissement du ski 5, du fait que ce dispositif de modification 6 participe à la résistance mécanique du ski 5.De manière remarquable,
  • d'une part, chaque butée d'arrêt en translation 103 est de nature à assurer l'arrêt en translation d'une tige 1 dans deux sens opposés S1, S2 de déplacement de la tige 1 selon son axe longitudinal 10, de manière à retenir la tige 1 pour la faire reculer (sens S2) lorsque le ski 5 est libéré de contraintes induisant sa flexion, et
  • d'autre part, chaque élément de transmission 2 est interposé entre la tige 1 et le ski 5, d'une manière telle que, lorsque ledit ski 5 est libéré de contraintes induisant sa flexion et que la tige 1 recule, cet élément de transmission 2 applique sur le ski 5 une action qui provoque une modification de géométrie radiale inverse à celle provoquée lors du déplacement de la tige 1 vers l'extrémité dudit ski 5 équipée de cet élément de transmission 2.
Remarkably, instead, as in the case of the international application WO 02/40115 to exploit the relative displacement of the rod 1 to cause the expansion of a part which communicates its deformation to the ski 5, the modification device 6 of the radial geometry according to the invention comprises at least one element 2, said transmission element 2 which, interposed between the rod 1 and the ski 5:
  • each transform a relative movement 100 of the rod 1, oriented along its longitudinal axis 10 and directed towards one end of the ski (direction S1), in a second displacement 200 oriented in a direction intersecting said longitudinal axis 10 and directed towards the outside ski 5,
  • each apply this displacement 200 in a selected location of the ski 5, so that, during said relative displacement 100 of the rod 1, cause a thrust action causing the deformation of the ski 5 according to its cross section, transverse deformation translated, in particular, by a spacing in the upper part of the ski and, by the desired modification of the geometry of the lower face 50 of this ski 5. Remarkably, the modification device 6 comprises at least one row 20 of a plurality of elements transmission 2 spaced apart and oriented relative to the rod 1, this row 20 of transmission elements 2 being located at least on one side of the rod 1. According to a first embodiment (Figures 1 to 4), the modifying device 6 comprises at least one rod 1 and two rows 20 of transmission elements 2 spaced apart and oriented with respect to the rod 1, these rows 20 being located on both sides other of the rod 1, approximately symmetrically with respect to the longitudinal axis 10 of this rod 1. According to a second embodiment (FIG. 5), the modification device 6 comprises at least one set of two rods 1 which extend substantially parallel to each other and each between a stop stop in translation 103 fixed on the ski 5 and the part of the ski 5 whose radial geometry must be modified.According to a variant of the second embodiment, the device modification 6 comprises at least one set 30 of two rods 1 which extend substantially parallel to one of the banks 52, 53 of the ski 5 and each between a stop stop in translation 103 fixed on the ski 5 and the part of the ski 5 whose radial geometry must be modified. Remarkably, the transmission elements 2 of each row 20 extend substantially parallel to each other, so as to form an angle substantially constant with the longitudinal axis 10 of the rod 1 with which they are associated. According to a variant, the transmission elements 2 of each row 20 extend so as to form with the longitudinal axis 10 of the rod 1 to which they are associated, an angle that varies from one transmission element 2 to the other. However that may be, the modification device 6 acts on the ski 5 at a plurality of points spaced in the longitudinal direction of said ski 5 and not in a concentrated manner as in the case of the device of the international application WO 02/40115. The respect of the aforementioned technical characteristics makes it possible to better control the longitudinal dimension of each part of the ski 5 in which the radial geometry must be modified. Also, the structure and the mode of operation of the modification device 6 allow the designer of the ski 5 to to increase the capacity of the cross-section of the ski 5 to be deformed, without this resulting in a weakening of the ski 5, because this modification device 6 contributes to the ski's mechanical strength.
  • firstly, each stop stop in translation 103 is such as to ensure the translation stop of a rod 1 in two opposite directions S1, S2 of displacement of the rod 1 along its longitudinal axis 10, so as to retain the rod 1 to make it back (direction S2) when the ski 5 is released from constraints inducing its flexion, and
  • on the other hand, each transmission element 2 is interposed between the rod 1 and the ski 5, in such a way that, when said ski 5 is released from stresses inducing its flexion and that the rod 1 retreats, this transmission element 2 applies on the ski 5 an action which causes a radial geometry modification inverse to that caused during the displacement of the rod 1 towards the end of said ski 5 equipped with this transmission element 2.

De manière également remarquable, chaque élément de transmission 2 est constitué et agit à la manière d'une bielle, c'est-à-dire qu'il consiste en une pièce résistante à la compression et articulée sur la tige 1 et sur le ski 5.Also remarkably, each element of transmission 2 is constituted and acts in the manner of a connecting rod, that is to say that consists of a piece resistant to compression and articulated on the rod 1 and on the ski 5.

L'homme du métier est à même de déterminer la manière la plus appropriée pour réaliser ces liaisons articulées. The skilled person is able to determine the most suitable for making these articulated links.

Par exemple, la tige 1 et le ski 5 comportent des encoches et chaque élément de transmission 2 comporte des extrémités qui sont façonnées de manière à s'ajuster dans ces encoches.For example, the rod 1 and the ski 5 have notches and each transmission element 2 has ends that are shaped from to fit in these notches.

Le respect des caractéristiques techniques précitées permet d'obtenir le résultat de l'invention selon lequel le dispositif de modification 6 du type précité, après suppression d'une contrainte de flexion ayant engendré une modification de la géométrie radiale du ski 5, garantit le rétablissement de cette géométrie radiale à son état initial.The respect of the aforementioned technical characteristics allows obtain the result of the invention according to which the modification device 6 of the aforementioned type, after removal of a bending stress which has generated a modification of the radial geometry of the ski 5, guarantees the restoration of this radial geometry in its initial state.

L'adaptation d'un ski aux conditions de l'environnement peut être effectuée par remplacement de chaque tige 1, par exemple, par une tige 1 plus longue ou plus courte et/ou plus rigide ou moins rigide que celle en place.The adaptation of a ski to the conditions of the environment can be performed by replacing each rod 1, for example, with a rod 1 more long or shorter and / or more rigid or less rigid than that in place.

Avantageusement, le dispositif de modification 6 comprend un moyen de réglage 9 de la longueur utile de chaque tige 1 qu'il comporte, c'est-à-dire de la longueur de la tige 1 entre, d'une part, la butée d'arrêt en translation 103 avec laquelle elle coopère et, d'autre part, la rangée d'éléments de transmission 2 avec laquelle la tige 1 coopère.Advantageously, the modification device 6 comprises a adjusting means 9 of the useful length of each rod 1 that it comprises, that is to say the length of the rod 1 between, on the one hand, the stop stop in translation 103 with which it cooperates and, on the other hand, the row of elements transmission 2 with which the rod 1 cooperates.

Par exemple, ce moyen de réglage 9 permet d'appliquer à la tige 1, une précontrainte de compression de valeur prédéterminée, de manière à anticiper l'action de poussée de cette tige 1 sur les éléments de transmission 2, lors de la flexion du ski 5.For example, this adjustment means 9 makes it possible to apply to the rod 1, compression prestressing of predetermined value, so as to anticipate the thrust action of this rod 1 on the transmission elements 2, when flexing the ski 5.

Par exemple, ce moyen de réglage 9 :

  • est interposé entre la butée d'arrêt en translation 103 et l'extrémité passive 101 de la tige 1 destinée à coopérer avec cette butée 103 et
  • peut être contracté ou expansé sensiblement selon l'axe longitudinal 10 de la tige 1. Par exemple, le moyen de réglage 9 comprend deux pièces 90, 91 assemblées par des parties filetée et taraudée.
  • l'une 90 de ces pièces 90, 91 présente au moins une face 92, 93 destinée à coopérer avec la butée d'arrêt en translation 103,
  • l'autre pièce 91 présente un moyen d'immobilisation 94 de l'extrémité passive de la tige 1, de manière telle qu'une action de poussée ou de traction puisse être transmise à la tige 1.
For example, this adjustment means 9:
  • is interposed between the stop stop in translation 103 and the passive end 101 of the rod 1 intended to cooperate with this stop 103 and
  • can be contracted or expanded substantially along the longitudinal axis 10 of the rod 1. For example, the adjustment means 9 comprises two parts 90, 91 assembled by threaded and threaded portions.
  • one 90 of these parts 90, 91 has at least one face 92, 93 intended to cooperate with the translational stopper 103,
  • the other piece 91 has a means of immobilization 94 of the passive end of the rod 1, so that a pushing or pulling action can be transmitted to the rod 1.

Par exemple, ce moyen d'immobilisation 94 comprend un alésage dans lequel l'extrémité de la tige située au niveau de la dite butée se trouve engagée et immobilisée.For example, this immobilizing means 94 comprises a bore in which the end of the rod situated at the level of the said abutment is committed and immobilized.

Avantageusement, au moins l'une des pièces 90, 91 constituant le moyen de réglage 9 présentent des méplats (non représentés) pour leur actionnement à l'aide de clefs plates (non représentés).Advantageously, at least one of the pieces 90, 91 constituting the adjustment means 9 have flats (not shown) for their actuation using flat keys (not shown).

D'une autre manière notable, le dispositif de modification 6 comprend un moyen d'absorption 12 d'un déplacement en translation de chaque tige 1 qui s'étend au-delà d'une limite prédéterminée, de manière telle que lorsque la flexion du ski 5 dépasse elle-même une valeur prédéterminée, le dispositif de modification 6 soit, en quelque sorte, débrayé et ne subisse pas de dommage affectant son fonctionnement.In another notable manner, the modification device 6 comprises means 12 for absorbing a displacement in translation of each rod 1 which extends beyond a predetermined limit, in such a way when the bending of the ski 5 itself exceeds a predetermined value, the modification device 6 is, in a way, disengaged and does not suffer from damage affecting its operation.

Par exemple, le moyen d'absorption 12 est situé au niveau de chaque butée d'arrêt en translation 103 et consiste en un mécanisme 12 d'effacement élastique de chaque butée d'arrêt en translation 103, lorsque celle-ci reçoit de la tige 1 une action dont l'intensité est située au-delà de la valeur prédéterminée, l'effacement de cette butée 103 permettant ainsi de libérer la tige 1 pour autoriser son déplacement au-delà de la limite prédéterminée.For example, the absorption means 12 is located at the level of each stop stop in translation 103 and consists of a mechanism 12 of elastic erasure of each stop stop in translation 103, when it receives from the stem 1 an action whose intensity is located beyond the predetermined value, the erasure of this stop 103 thus making it possible to release rod 1 to allow its movement beyond the limit predetermined.

Par exemple, pour constituer le moyen d'absorption 12 :

  • celle 90 des pièces 90, 91 du moyen de réglage 9 qui est destinée à coopérer avec la butée d'arrêt en translation 103,
    • est sensiblement cylindrique de révolution et guidée en translation dans un alésage 95 approximativement aligné sur l'axe longitudinal 10 de la tige 1,
    • présente une gorge périphérique en V de manière à porter deux faces 92, 93 coniques,
  • la butée d'arrêt en translation est constituée par au moins une pièce 103 qui portant une surface arrondie 104, est guidé en translation vers la gorge périphérique en V et élastiquement sollicité vers cette gorge de manière à y être fermement maintenue.
For example, to constitute the absorption means 12:
  • that 90 of the parts 90, 91 of the adjustment means 9 which is intended to cooperate with the stop stop in translation 103,
    • is substantially cylindrical in revolution and guided in translation in a bore 95 approximately aligned with the longitudinal axis 10 of the rod 1,
    • has a V-shaped peripheral groove so as to bear two conical faces 92, 93,
  • the stop translational stop is constituted by at least one piece 103 which carries a rounded surface 104, is guided in translation towards the V-shaped peripheral groove and resiliently biased towards this groove so as to be firmly maintained there.

Dans une version de réalisation (non représentée), le dispositif de l'invention comprend au moins une tige 1 qui s'étend sur sensiblement toute la longueur du ski 5.In an embodiment (not shown), the device for the invention comprises at least one rod 1 which extends over substantially the entire length of the ski 5.

Par exemple, la tige 1, passe sous le moyen de fixation 8 de la chaussure de ski.For example, the rod 1 passes under the fastening means 8 of the ski boot.
