Abstract

L'invention concerne un procédé et un dispositif de déplacement dans la neige comportant un moteur à combustion en tant que source d'énergie, et elle tente d'apporter des solutions aux limitations et à l'inadéquation des agencements structurels de dispositifs actuels, à l'aide de propriétés nouvelles et perfectionnées. Selon l'invention, les problèmes sont résolus par un procédé de déplacement sur la neige, dans lequel on conduit le dispositif de déplacement (22) -comprenant un ensemble ski de direction (25) et un ensemble courroies porteuses (27) entraînées par un moteur- tout en étant debout sur la plate-forme (23) de ce dispositif (22) et en agrippant le guidon (25) de direction du dispositif (22), la position basse de la plate-forme (23) servant à stabiliser le dispositif. L'invention concerne donc un dispositif de déplacement selon le procédé décrit, et notamment un dispositif, qui outre le fait d'être stable lors de son déplacement, lorsque le conducteur se tient debout sur la plate-forme (23) conçue à cet effet ou sur l'emplacement (23) réservé aux pieds, comporte une meilleure position de conduite si le conducteur s'assied sur la partie siège (91) du dispositif (22). En outre, l'invention concerne un dispositif (22) dont la surface extérieure des courroies porteuses comprend des surfaces de contact, lesquelles sont conçues pour pousser vers le bas la partie supérieure de chaque courroie (28), et donc, la plate-forme ou l'emplacement pour les pieds, stabilisant ainsi la conduite.
