Abstract

The invention relates to a device making it possible to ski in the fashion of the "monoski", while facilitating the running of the skis as well as the rapid return to the conventional ski, by means of uncoupling. The device consists of several joining pieces 1 articulated on spindles 3 which are themselves held in supports 2 which, fixed firmly on the skis 8, ensure the lateral linking thereof. The joining pieces 1 held on the supports 2 between the TEFLON sheets 6 by milled wheels 5 permit the adjustment of the longitudinal movement of the skis as well as the assembly or disassembly of the latter. A fixing screw 7 passing through a hole 13 in the joining piece 1 makes it possible to make the device "monobloc". This device is intended particularly for practising skiing, in monoski fashion, while using two conventional skis.

Description

La présente invention concerne un dispositif pour rendre deux skis traditionnels, solidaires, tout en ayant la possibilité d'avancer ou de reculer un ski parallèlement par rapport à l'autre ski, dans le sens longitudinal, ou d'en faire un systeme "monobloc" avec désaccouplement rapide. The present invention relates to a device for making two traditional skis, integral, while having the possibility of advancing or reversing a ski parallel to the other ski, in the longitudinal direction, or of making it a "monobloc" system "with quick uncoupling.

Le pratique du ski est faîte traditionnellement par deux skis séparés ou par un ski large dénommé "monoski", lequel présente certains inconvénients . Difficulté pour un skieur débutant de le pratiquer sans risque et sans crainte, . Difficulté pour remonter les pentes avec les moyens mécaniques usuels non adaptés à ce type de ski (télécabine, télésiège, remonte-pente..) . Difficulté d'avancer à l'aide des jambes sur les longs faux plats; seule la force des bras le permet, . Impossibilité de mobilité longitudinale d'un ski par rapport à 11 au tre, . Impossibilité, dès l'arrivée du mauvais temps, de rejoindre la station en pratiquant le ski traditionnel, . Difficulté, lors d'une chute en neige profonde, de se dégager sans indépendance des skis, . Inadaptation du "monoski" a la glace, . Difficulté de stabilité latérale sur les pistes présentant des rails provoqués par l'usage du ski traditionnel. Skiing is traditionally done by two separate skis or by a wide ski called "monoski", which has certain drawbacks. Difficulty for a beginner skier to practice it safely and without fear,. Difficulty climbing the slopes with the usual mechanical means not suited to this type of skiing (cable car, chairlift, ski lift, etc.). Difficulty advancing with the help of legs over long, flat flats; only the strength of the arms allows,. Impossibility of longitudinal mobility of a ski compared to 11 to tre,. Impossibility, from the arrival of bad weather, to reach the resort by practicing traditional skiing,. Difficulty, during a fall in deep snow, to disengage without independence of the skis,. Unsuitability of the "monoski" for ice,. Difficulty in lateral stability on tracks with rails caused by the use of traditional ski.

Le dispositif selon l'invention permet de remédier à ces inconvénients, tout en préservant les avantages du "monoski". En effet, il permet de skier en trace serrée, tout en conservant la possibilité, si le skieur le désire, de revenir rapidement aux skis séparés, par simple désaccouplement. Il permet également, lorsque les skis sont solidaires, une facilité pour le transport. The device according to the invention overcomes these drawbacks, while preserving the advantages of the "monoski". Indeed, it allows skiing in a tight track, while retaining the possibility, if the skier wishes, to quickly return to separate skis, by simple uncoupling. It also allows, when the skis are secured, ease of transport.

Le dispositif comprend au moins des supports fixés devant et derrière sur les skis, reliés entre eux par une ou plusieurs pièces de jonction assurant la liaison des skis, soit au moins deux ensembles de liaison. The device comprises at least supports fixed in front and behind on the skis, interconnected by one or more connecting pieces ensuring the connection of the skis, or at least two connection assemblies.

Les pièces de jonction pivotant sur des axes fixés dans les supports permettent d'avancer ou de reculer les deux skis l'un par rapport à l'autre, parallèlement, et de skier serré pour en améliorer l'effica- cite et l'esthétique. The junction pieces pivoting on axes fixed in the supports allow the two skis to move forward or backward in relation to each other, in parallel, and to ski tight to improve their efficiency and aesthetics .

L'ensemble peut etre rendu "monobloc" au moyen d'un systeme de blocage. Une molette permet le démontage rapide et le retour au ski traditionnel en terrains difficiles ou lors des remontées mécaniques non adaptées. Le dispositif installé sur les skis, favorise le transport dans les remontées mécaniques non conçues pour le "monoski". Il permet, en outre, l'apprentissage du "monoski" en haut des pistes et supprime toute crainte a l'éleve débutant dans ce sport, par le fait qu'il peut, à tout moment, revenir au ski traditionnel.The whole can be made "monobloc" by means of a blocking system. A wheel allows quick disassembly and return to traditional skiing in difficult terrain or during unsuitable ski lifts. The device installed on the skis, promotes transport in ski lifts not designed for "monoski". It also allows the learning of "monoski" at the top of the slopes and removes any fear for the student starting out in this sport, by the fact that he can, at any time, return to traditional skiing.
