  • the skates which are described in US-PS 475.926, 539.641 and 568.547, are used for skating on ice of good quality. They are produced with longer blades than common, but the longest are not longer than 50 cm, as described in US-PS 568.547.

  • a common winter activity is skiing.
  • a participant in this activity is dependent on the user's kick-off with legs and ski sticks, to move the user's body over the snow and on the snows conditions.
  • the skier needs a sufficient quantity of snow to go on the snow, and the snow must be of good quality, not too coarse, or icy. Ice can affect on the skier so the skier loses control and the balance when skiing on the surface.

When skating the user basically train legs and the lower part of the body and not the upper body.

Abstract

La présente invention concerne un ski de fond permettant de skier en particulier sur de la glace, et sur une surface recouverte de glace. Le ski de l'invention comprend une combinaison d'un corps de ski (1) ayant une tension appropriée, en tant que surface portante, présentant une surface supérieure (2) dotée d'une fixation de ski (10) et une surface inférieure (3), un paire de lames (4) analogues à celles du patinage de vitesse, étant reliées sous forme d'un ensemble de couplage avant et arrière dans la direction longitudinale. La distance entre les lames faisant partie d'un même paire peut être égale à la largeur du corps de ski, et, entre les lames d'une même paire sont connectés des corps plats (11) ayant une base de glissement qui présente une distance par rapport aux bords des lames amovibles. La base de glissement est conçue pour agir comme un ski sur la neige lorsque la qualité de la glace est mauvaise et par temps de neige. Les deux ensembles de couplage permettent un mouvement autour d'un axe horizontal, mais pas plus, ou un mouvement quelconque autour d'un axe vertical. Selon l'invention, la flexibilité du corps de ski sert à la fois à absorber les chocs et à amplifier les mouvements de jambe. Différents modes de réalisation de l'invention lui permettent de s'adapter aux deux techniques de ski et le ski peut être doté d'un système de freinage comprenant un frein à main (8) relié à un bloc de freinage (7). Le ski de l'invention donne naissance à une nouvelle activité de sports d'hiver permettant en particulier de skier sur des surfaces recouvertes de glace. Le ski de l'invention permet d'atteindre des vitesses élevées sur de la glace dure et peut être utilisé sur des lacs gelés et sur des pistes de ski verglacées. Les skis de l'invention peuvent en général être utilisés de la même façon que le sont les skis de fond ordinaires sur la neige.
