Definitions

  • the invention relates to a motorized device for skis, in particular for touring skis, which supports the ascent movement and thus with less physical performance that needed to go uphill, alternating ski after pushing, can be performed.
  • the invention relates to a sports equipment, as indicated in claims 1 and 5.
  • a sports equipment in particular a climbing ski or touring ski is known, which has a fold-out Abcetschaufel on the seen in the direction of movement front end portion.
  • This shovel is arranged on the ski so that it can be folded out in the direction of the ground and thus can intervene in the snow.
  • the downwardly foldable Abcetschaufel is connected to a linkage, which is guided for binding. If the user lowers his foot while walking and thus loads the binding with his body weight, the linkage is activated by the body weight. As a result, the Ab complicatschaufel is unfolded and also pulled backwards, so that the ski slides forward.
  • the in the DE 649 153 described embodiment has the disadvantage that the Abagneschaufel must engage in the snow to be able to achieve that the ski is moved by the Abagneschaufel forward.
  • the impeller In hard snow, especially in ice or compact snow, the impeller can not be sufficiently pressed into the snow to ensure a good grip.
  • the snow ground of the repeller blade can not resist enough to absorb the force transmitted by the repeller blade.
  • the Absteschaufel can not achieve the desired effect in the prevailing snow conditions.
  • a sports device with the features of the preamble of claim 1 is made DE 10 2005 043 810 A1 known.

  • the invention has the object to design a touring ski so that the movement and the posture of Tourenskigehers is not changed, only the energy consumption can be reduced by motor support.
  • This object of the invention is achieved by a motor climbing aid for touring skiers or by a sports equipment, in particular by a Tourenskianssen, with the features of claim 1.
  • the invention solves the problem in that between Tourenskioberseite and touring ski binding a sliding device is mounted, which is mounted on the top of the ski, or integrated in the ski and the touring ski binding is mounted on the slider.

  • the movement of the touring ski binding can be made with known technology such as rack, threaded rod, pneumatic or hydraulic cylinder or with cable.
  • a first possible embodiment is a ski touring, consisting of a sliding surface, to which a fur or fur-like plastic is attached to prevent slipping back when walking uphill. Furthermore, there is a touring ski binding on the ski touring. The ski boot snaps into this binding, creating the connection between touring skis and touring skis.
