  • the invention relates to a sports device for sliding over a slidable surface.
  • sports equipment is used in particular on snow, but also on other slippery surfaces such as Dune sand used.
  • These devices also include in particular "ski sled” or “monoski” with two runners arranged next to one another and a plate arranged above them and supporting the athlete, which is connected to the runners via a device in such a way that pivoting movements about a longitudinal axis of the supporting plate are directed onto the Transfer runners.

  • Devices are described in the patent and utility model AT 372052, DE 8408574, DE 8601337, DE 8626399 and DE 8619567, which are composed of several components (gears and / or lever arrangements).
  • a common characteristic of these inventions is that the pivoting movement of the supporting plate takes place in both directions about the same longitudinal axis.
  • Another common characteristic is that the mechanical components of the device, via which the swiveling movement is transmitted to the runners in both directions, are arranged symmetrically on essentially the same level. After all, all facilities consist of more than two essential components.

  • the advantages of the simplicity and robustness of the design, in particular of snowboards compared to the sports equipment described above (which have the disadvantage of a complex construction) outweigh the disadvantages of snowboards.
  • There have recently been attempts to achieve a separation of the load-bearing plate and the sliding surface (US 2002/8360) with the elimination of mechanical components, in order to be able to drive in an unbuckled manner and more flexibly. With the rigid connection used here, however, only one skid can be attached, as a result of which the stability of the sports equipment is greatly reduced, particularly when cornering.
  • the inventive task is to develop a sports device that corresponds to the external features of the devices described above, but is characterized by an improved device for transmitting the pivoting movement of the plate to the runners.

Abstract

L'invention concerne un instrument de sport d'hiver comprenant deux patins adjacents et une plaque posée au-dessus des deux patins et portant le sportif. 2.1 De tels instruments de sport d'hiver ( ski articulé', monoski') présentent actuellement l'inconvénient que la conception, notamment les dispositifs de transmission du mouvement pivotant de la plaque support aux patins sont techniquement trop coûteux, notamment par rapport aux planches à neige simples et robustes. La présente invention vise donc une conception simple et robuste desdits instruments de sport d'hiver. 2.2. A cet effet, le dispositif de transmission du mouvement pivotant au système composé de seulement une paire de deux composants deux supports angulaires - est réduit. La plaque support sert de levier, et, lors de son pivotement, des forces agissant de manière opposées par les supports (mutuellement espacés latéralement) sont retransmises aux deux patins qui alors suivent le mouvement pivotant de la plaque support. 2.3. Ce dispositif convient notamment comme instrument de sport apte aux virages sur les pistes de ski (modèle destiné à une utilisation debout) et les pistes de luge (modèle de type luge).
