Abstract
Description
SYSTEME DE REMONTE-PENTE LIFT SYSTEM
La présente invention concerne un système de remonte-pente, pouvant être utilisé notamment pour remonter des pentes enneigées.The present invention relates to a ski lift system, which can be used in particular for climbing snow-covered slopes.
On connaît un système de remonte-pente du type comprenant au moins une planche de glisse adaptée à supporter un individu, des moyens de propulsion adaptés à déplacer la planche de glisse et l'individu, et des premiers moyens de fixation adaptés à fixer de façon mobile les moyens de propulsion à la planche de glisse.There is known a ski lift system of the type comprising at least one gliding board adapted to support an individual, propulsion means adapted to move the gliding board and the individual, and first fixing means adapted to fix so mobile means of propulsion to the gliding board.
Un tel système est décrit par exemple dans la demande de brevet EP 776 682. L'inconvénient majeur d'un tel système est que, quand la planche de glisse et l'individu sont propulsés par les moyens de propulsion, l'individu doit s'aider de ses bâtons de ski pour maintenir son équilibre. Or, quand les moyens de propulsion sont utilisés pour remonter la pente, les bâtons de ski s'avèrent encombrants et inefficaces pour maintenir l'individu en équilibre.Such a system is described for example in patent application EP 776 682. The major drawback of such a system is that, when the gliding board and the individual are propelled by the propulsion means, the individual must s help with your ski poles to maintain your balance. However, when the means of propulsion are used to ascend the slope, the ski poles prove to be bulky and ineffective in keeping the individual in balance.
La présente invention a pour objet de remédier aux inconvénients précités, et notamment à permettre le maintien en équilibre de l'individu, même quand le système de remonte pente est utilisé pour remonter des pentes ayant une forte inclinaison.The object of the present invention is to remedy the aforementioned drawbacks, and in particular to allow the individual to be kept in balance, even when the ascent system is used to ascend slopes having a steep inclination.
Selon l'invention, le système du type précité comprend un dispositif de maintien adapté à servir de point d'appui à l'individu et des seconds moyens de fixation adaptés à fixer de façon mobile le dispositif de maintien à la planche de glisse.According to the invention, the system of the aforementioned type comprises a holding device adapted to serve as a support point for the individual and second fixing means adapted to movably fix the holding device to the gliding board.
Par un tel système, l'individu est parfaitement maintenu en équilibre, même quand la pente qui est remontée, est à forte inclinaison. D'autres avantages et particularités de la présente invention apparaîtront mieux dans la description détaillée qui va suivre.By such a system, the individual is perfectly kept in balance, even when the slope which has gone back up, is with strong inclination. Other advantages and features of the present invention will become more apparent from the detailed description which follows.
Aux dessins annexés, donnés à titre d'exemple non limitatif : la figure 1 est une vue de dessus en perspective d'une planche de glisse à laquelle sont fixés des moyens de propulsion et un dispositif de maintien ; - la figure 2 est une vue partielle de dessus, en perspective, d'une planche de glisse munie d'un dispositif de maintien ; la figure 3 est une vue en perspective, de coté, d'un dispositif de maintien. - la figure 4 est une vue de dessous, en perspective, d'une planche de glisse à la quelle sont fixés des moyens de propulsion ; la figure 5 est une vue en coupe transversale d'une planche de glisse à laquelle sont fixés des moyens de propulsion ; la figure 6 est une vue en coupe longitudinale d'une planche de glisse à laquelle sont fixés des moyens de propulsion ; la figure 7 est une vue en coupe d'un arbre de rotation d'un rouleau utilisé comme moyen de propulsion ; et la figure 8 est une vue schématique de côté d'une planche de glisse à laquelle sont fixés des moyens de propulsion. Comme on peut le voir aux figures annexées, un système de remonte-pente comprend au moins une planche de glisse 1 (en l'espèce, un surf des neiges 1), des moyens de propulsion 2 et des premiers moyens de fixation 3 qui sont adaptés à fixer de façon mobile les moyens de propulsion 2 au surf 1. Le surf 1 est adapté à supporter un individu, en l'occurrence un surfeur. Les moyens de propulsion 2 sont adaptés à déplacer le surf 1 et le surfeur.In the accompanying drawings, given by way of nonlimiting example: FIG. 1 is a perspective view from above of a gliding board to which are propelled means and a holding device; - Figure 2 is a partial top view, in perspective, of a gliding board provided with a holding device; Figure 3 is a perspective view, from the side, of a holding device. - Figure 4 is a bottom view, in perspective, of a gliding board to which are fixed propulsion means; Figure 5 is a cross-sectional view of a gliding board to which are fixed propulsion means; Figure 6 is a longitudinal sectional view of a gliding board to which are fixed propulsion means; Figure 7 is a sectional view of a rotation shaft of a roller used as a propulsion means; and Figure 8 is a schematic side view of a gliding board to which are fixed propulsion means. As can be seen in the appended figures, a ski lift system comprises at least one gliding board 1 (in this case, a snowboard 1), propulsion means 2 and first means of attachment 3 which are adapted to movably secure the propulsion means 2 to the surf 1. The surf 1 is adapted to support an individual, in this case a surfer. The propulsion means 2 are adapted to move the surf 1 and the surfer.
Selon l'invention, le système de remonte-pente comprend un dispositif de maintien 4 et des seconds moyens de fixation 5 qui sont adaptés à fixer de façon mobile le dispositif de maintien 4 au surf 1. Le dispositif de maintien 4 est adapté à servir de point d'appui au surfeur.According to the invention, the ski lift system comprises a holding device 4 and second fixing means 5 which are adapted to movably fix the holding device 4 to the surf 1. The holding device 4 is suitable for serving point of support for the surfer.
L'emploi d'un système selon la présente invention est le suivant : une fois arrivé en bas d'une piste enneigée, le surfeur fixe au surf 1, d'une part, les moyens de propulsion 2 par les premiers moyens de fixation 3 (les moyens de propulsion 2 se trouvant sous de surf 1), et, d'autre part, le dispositif de maintien 4 par les seconds moyens de fixation 5 (le dispositif de maintien se trouvant au-dessus du surf 1) . Le surfeur, après avoir mis en marche un moteur 6 adapté à actionner les moyens de propulsion 2, peut remonter la pente enneigée sur son surf 1 en se maintenant en équilibre par le dispositif de maintien 4. De façon avantageuse, les premiers moyens de fixation 3 sont adaptés à fixer les moyens de propulsion 2 au surf 1 de façon amovible, et les seconds moyens de fixation 5 sont adaptés à fixer le dispositif de maintien 4 au surf 1 de façon amovible. L'utilisateur peut ainsi transporter dans un sac à dos, pendant les phases de descentes des pentes enneigées, les moyens de propulsion 2, les premiers moyens de fixation 3, le dispositif de maintien 4 et les seconds moyens de fixation 5.The use of a system according to the present invention is as follows: once arrived at the bottom of a snowy track, the surfer fixes on the surf 1, on the one hand, the propulsion means 2 by the first fixing means 3 (the propulsion means 2 being under the surf 1), and, on the other hand, the holding device 4 by the second fixing means 5 (the holding device being above the surf 1). The surfer, after having started a motor 6 adapted to actuate the propulsion means 2, can go up the snowy slope on his surfboard 1 while maintaining his balance by the holding device 4. Advantageously, the first fixing means 3 are adapted to fix the propulsion means 2 to the surf 1 in a removable manner, and the second fixing means 5 are adapted to fix the holding device 4 to the surf 1 in a removable manner. The user can thus carry in a backpack, during the descending phases of snow-covered slopes, the propulsion means 2, the first means of attachment 3, the holding device 4 and the second attachment means 5.
Comme on peut le voir aux figures 1 à 3, le dispositif de maintien 4 comprend une barre de maintien 7 dont une première extrémité est adaptée à coopérer avec les seconds moyens de fixation 5 et dont l'extrémité opposée comporte une poignée 8. La poignée 8 pourrait être remplacée par un guidon ou tout autre élément similaire. La poignée 8 comporte des moyens de commande manuelle 30 (par exemple des boutons) qui sont connectés au moteur 6 et permettent au surfeur de commander le moteur 6 et donc les moyens de propulsion 2. Cette connexion peut être faite, par exemple, par un câble électrique 31. Dans le présent exemple, le moteur 6 est un moteur électrique.As can be seen in Figures 1 to 3, the holding device 4 comprises a holding bar 7 whose first end is adapted to cooperate with the second fixing means 5 and whose opposite end comprises a handle 8. The handle 8 could be replaced by a handlebar or any other similar element. The handle 8 comprises manual control means 30 (for example buttons) which are connected to the motor 6 and allow the surfer to control the motor 6 and therefore the propulsion means 2. This connection can be made, for example, by a electric cable 31. In the present example, the motor 6 is an electric motor.
Le dispositif de maintien 4 est conformé de façon à adapter la distance entre le surf 1 et la poignée 8 à la taille de l'utilisateur. La barre de maintien 7 pourrait être télescopique.The holding device 4 is shaped so as to adapt the distance between the surf 1 and the handle 8 to the size of the user. The holding bar 7 could be telescopic.
Comme on peut particulièrement bien le voir aux figures 2 et 3, le dispositif de maintien 4 comprend un élément de liaison 9 composé d'une pluralité de pieds 35 qui sont disposés selon les arrêtes d'une pyramide. L'extrémité 10 de chaque pied 35 située du côté de la base de la pyramide est adaptée à coopérer avec les seconds moyens de fixation 5, et l'extrémité 11 de chaque pied 35 située du côté du sommet de la pyramide est adaptée à coopérer avec la barre de maintien 7. En l'espèce, l'élément de liaison 9 est un trépied 9 dans lequel la barre de maintien 7 est montée coulissante. Les moyens de propulsion 2 sont adaptés à être fixés au surf 1 de sorte que la propulsion se fasse selon la direction longitudinale du surf 1.As can be clearly seen in Figures 2 and 3, the holding device 4 comprises a connecting element 9 composed of a plurality of feet 35 which are arranged along the edges of a pyramid. The end 10 of each foot 35 located on the side of the base of the pyramid is adapted to cooperate with the second fixing means 5, and the end 11 of each foot 35 located on the side of the top of the pyramid is adapted to cooperate with the holding bar 7. In this case, the connecting element 9 is a tripod 9 in which the holding bar 7 is slidably mounted. The propulsion means 2 are adapted to be fixed to the surf 1 so that the propulsion takes place in the longitudinal direction of the surf 1.
Selon un premier mode de réalisation particulier, comme on peut le voir à la figure 6, les moyens de propulsion 2 comprennent au moins deux rouleaux 12 (en l'espèce, il y a trois rouleaux 12). Chaque rouleau 12 comporte, sur sa surface périphérique, des empreintes 13 qui sont adaptées à permettre l'adhérence du système sur la neige.According to a first particular embodiment, as can be seen in FIG. 6, the propulsion means 2 comprise at least two rollers 12 (in this case, there are three rollers 12). Each roller 12 has, on its peripheral surface, imprints 13 which are adapted to allow the adhesion of the system on snow.
Au moins un des rouleaux 12 est solidaire d'un arbre de rotation 14 dont une première extrémité 15 est montée libre en rotation dans un palier lisse 16, et dont l'extrémité opposée 17 est reliée au moteur 6. Un tel rouleau 12 peut être qualifié de rouleau moteur. Avantageusement, le palier lisse 16 est muni d'un roulement à billes afin de réduire les frottements. Dans le cas où il y a deux rouleaux 12, le rouleau moteur est préférentiellement placé à l'avant du surf 1, et, dans le cas où il y a trois rouleaux 12, il est préférentiellement en position centrale.At least one of the rollers 12 is integral with a rotation shaft 14, a first end 15 of which is mounted for free rotation in a plain bearing 16, and the opposite end 17 of which is connected to the motor 6. Such a roller 12 can be qualified as a motor roller. Advantageously, the plain bearing 16 is provided with a ball bearing in order to reduce friction. In the case where there are two rollers 12, the drive roller is preferably placed in front of the surf 1, and, in the case where there are three rollers 12, it is preferably in the central position.
Les autres rouleaux 12 (ceux qui ne sont pas des rouleaux moteurs) sont solidaires d'un arbre de rotation 14 dont chaque extrémité est montée libre en rotation dans un palier lisse 16. De tels rouleaux peuvent être qualifiés de rouleaux porteurs.The other rollers 12 (those which are not driving rollers) are integral with a rotation shaft 14, each end of which is mounted for free rotation in a smooth bearing 16. Such rollers can be qualified as carrying rollers.
Comme on peut le voir à la figure 7, l'arbre de rotation 14 comprend des moyens adaptés à' ajuster la longueur de l'arbre de rotation 14 à la dimension du surf 1 (dans le présent exemple, à la largeur du surf 1). En l'occurrence, l'arbre de rotation 14 comprend un cylindre creux 18 et une tige 19 qui est montée coulissante dans le cylindre 18. Le cylindre creux 18 comporte, sur sa surface périphérique, plusieurs orifices 20 et la tige 19 comprend, sur sa surface périphérique, un orifice complémentaire 21. L'ajustement de la longueur de l'arbre de rotation 14 à la dimension du surf 1 se fait par le coulissement de la tige 19 dans le cylindre creux 18 et par l'introduction d'une goupille dans l'orifice complémentaire 21 et l'orifice 20 lui faisant face. La goupille permet aussi de rendre la tige 19 et le cylindre 18 solidaires en rotation.As can be seen in Figure 7, the rotation shaft 14 comprises means adapted to 'adjust the length of the rotation shaft 14 to the dimension of the surf 1 (in the present example, to the width of the surf 1 ). In this case, the rotation shaft 14 comprises a hollow cylinder 18 and a rod 19 which is slidably mounted in the cylinder 18. The cylinder hollow 18 has, on its peripheral surface, several orifices 20 and the rod 19 comprises, on its peripheral surface, a complementary orifice 21. The length of the rotation shaft 14 is adjusted to the dimension of the surf 1 the sliding of the rod 19 in the hollow cylinder 18 and by the introduction of a pin in the complementary orifice 21 and the orifice 20 facing it. The pin also makes it possible to make the rod 19 and the cylinder 18 integral in rotation.
Selon un second mode de réalisation particulier, comme on peut le voir à la figure 4, les moyens de propulsion 2 comprennent au moins une chenille 22 (en l'espèce deux chenilles 22). Chaque chenille 22 est montée de façon rotative autour de deux rouleaux 23 et est adaptée à permettre l'adhérence du système sur de la neige. Les remarques faites précédemment sur les rouleaux dans le premier mode de réalisation particulier peuvent être répétées ici. Bien évidemment, dans le second mode de réalisation, les rouleaux 23 servent de rouleau de renvoi de la chenille 22 et, n'étant pas utilisés directement pour permettre l'adhérence du système à la neige, leur surface périphérique ne comporte pas d'empreintes. Par ailleurs, les premiers moyens de fixation 3 comprennent au moins un dispositif d'attache 24. Le dispositif d'attache 24 comprend deux éléments formant pince 25,26 qui sont mobiles l'un par rapport à l'autre entre une position écartée et une position ouverte dans laquelle ils sont adaptés à pincer la planche de surf 1 dans le sens de l'épaisseur. Avantageusement, la surface des éléments formant pince 25,26 qui est adaptée à être en contact avec le surf 1, est munie d'un élément protecteur.According to a second particular embodiment, as can be seen in FIG. 4, the propulsion means 2 comprise at least one track 22 (in this case two tracks 22). Each track 22 is rotatably mounted around two rollers 23 and is adapted to allow the adhesion of the system on snow. The remarks made previously on the rollers in the first particular embodiment can be repeated here. Obviously, in the second embodiment, the rollers 23 serve as a return roller for the track 22 and, not being used directly to allow the adhesion of the system to snow, their peripheral surface does not have any imprints . Furthermore, the first fixing means 3 comprise at least one fastening device 24. The fastening device 24 comprises two clamp elements 25, 26 which are movable relative to one another between a spaced apart position and an open position in which they are adapted to pinch the surfboard 1 in the thickness direction. Advantageously, the surface of the gripper elements 25, 26 which is adapted to be in contact with the surf 1, is provided with a protective element.
De plus, le dispositif d'attache 24 comprend un élément de manœuvre 27 qui adapté à faire passer les deux éléments formant pince 25,26 d'une position à l'autre. Le dispositif d'attache 24 peut comporter des moyens classiques garantissant une stabilité des deux éléments formant pince en position fermée et en position ouverte (par exemple un mécanisme à genouillère) .In addition, the fastening device 24 comprises an operating element 27 which is adapted to pass the two gripper elements 25, 26 from one position to the other. The fastening device 24 may include conventional means guaranteeing a stability of the two gripper elements in the closed position and in the open position (for example a toggle mechanism).
Dans le cas où le dispositif d'attache 24 est utilisé pour solidariser un rouleau 12,23 au surf 1, selon l'extrémité de l'arbre de rotation 14 concernée, un élément formant pince 25,26 est solidaire du moteur 6 ou du palier lisse 16 correspondant, la solidarisation pouvant être faite, par exemple, par soudage .In the case where the attachment device 24 is used to secure a roller 12,23 to the surf 1, depending on the end of the rotation shaft 14 concerned, a clamp element 25,26 is integral with the motor 6 or the corresponding plain bearing 16, the connection being able to be made, for example, by welding.
Comme on peut le voir à la figure 8, les premiers moyens de fixation 3 peuvent comporter des amortisseurs 29 afin d'améliorer l'adhérence des rouleaux 12 ou des chenilles 22.As can be seen in FIG. 8, the first fixing means 3 may include shock absorbers 29 in order to improve the adhesion of the rollers 12 or the tracks 22.
Par ailleurs, les seconds moyens de fixation 5 peuvent comprendre, eux aussi, au moins un dispositif d'attache 24 similaire à celui utilisé comme premier moyen de fixation 3. Bien évidemment, des adaptations géométriques et structurelles peuvent être faites afin de tenir compte des contraintes mécaniques spécifiques des moyens de propulsion 2 et de celles du dispositif de maintien 4. De plus, comme on peut le voir à la figure 2, dans le cas où le dispositif de maintien 4 comprend un trépied 9, le dispositif d'attache 24 comporte une réglette 28 qui est solidaire d'un des deux éléments formant pince 25,26 et qui est adaptée à être montée coulissante dans l'un des montants du trépied 9 de façon à permettre l'ajustement de la hauteur de la poignée 8 à la taille du surfeur. Bien évidemment, la présente invention n'est pas limitée au mode de réalisation décrit en détail au regard des figures annexées et de nombreuses modifications peuvent y être apportées.Furthermore, the second fastening means 5 can also include at least one fastening device 24 similar to that used as the first fastening means 3. Obviously, geometric and structural adaptations can be made to take account of the specific mechanical constraints of the propulsion means 2 and those of the holding device 4. In addition, as can be seen in FIG. 2, in the case where the holding device 4 comprises a tripod 9, the attachment device 24 includes a strip 28 which is integral with one of the two elements forming a clamp 25,26 and which is adapted to be slidably mounted in one of the uprights of the tripod 9 so as to allow the height of the handle 8 to be adjusted to the size of the surfer. Obviously, the present invention is not limited to the embodiment described in detail with regard to the appended figures and numerous modifications can be made to it.
Il est ainsi possible de remplacer le surf par un monoski ou par une paire de skis, le système comprenant alors une structure d'appui adaptée à rendre immobile chaque ski par rapport à l'autre et à servir de point d'appui du dispositif de maintien. Il est aussi possible d'utiliser la présente invention pour les planches de glisse du type ski sur herbe ou sur matériau en matière plastique. It is thus possible to replace the board with a monoski or with a pair of skis, the system then comprising a support structure adapted to make each ski immobile with respect to the other and to serve as a support point for the maintenance. It is also possible to use the present invention for gliding boards of the ski type on grass or on plastic material.
