Definitions

  • the invention concerns an Alpine pair ski with upturned tip and a main section with curved sides and approximately flat sliding surface.
  • pair ski refers to skis which are intended for use in pairs, i.e. with one ski on each foot, as opposed to so-called monoskis, where both feet are placed on a single ski.
  • the turning technique for pair skis is fundamentally different from that used for monoskis.
  • pair skis it is also normal for pair skis to be slightly wider at the front and the rear, i.e. the sides of the skis are gently curved. This helps to steer the skis through the turns with the least possible loss of kinetic energy. If the sides are curved too much, however, the skis will be difficult to control, since when they are on their edges they will cut into the snow at the front and the rear. Moreover, the grip on the snow in the middle of the ski will be reduced, which is a major disadvantage particularly on a hard cover, where everything depends on being able to skid well in the middle of the ski. For these reasons there is a limit to what can be achieved with this kind of curving of the sides.
  • An embodiment of the present invention provides a ski which makes it possible to turn with the least possible loss of kinetic energy, in that it does not cut too deeply into the snow, but still permits the attainment of a good grip when skidding. In this way a faster ski can be obtained which is still easy for the performer to control.
  • the skis are thus considerably wider at the front end than at the middle without being difficult to control, the lower edge of each side diverging upwards and thereby being raised sufficiently from the snow to prevent it from cutting into the snow when the skis are on their edges despite the increased ski width at the front end.
  • the upward divergence of the lower edge is closely connected with the pronounced outward curve (the increased width) at the front of the ski.
  • the ski can also be wider at the rear end and the lower edges of the sides can be raised correspondingly.
  • the outward curve will help the performer to make the turn with less skidding and thus a lesser loss of kinetic energy.
  • the outward curve at the front and possibly the rear will not prevent the (e.g. steel) edges on the central section from getting a grip. With the correct adjustment of angle and curve the skis will still be under full control, even if hard skidding is required.
  • the absolute width increase in millimetres is naturally dependent on the length of the front section. When this is short, the width increase will have to be in the lower part of the specified area.
  • An interesting design is one in which the length of the front section and the width increase are in the lower range, i.e. the front section is approximately 5 cm long, while the width increase is approximately 15%.
  • Fig. 3 is a perspective view of the front end of the ski.
  • Fig. 5 is another embodiment viewed from below.

  4. Un ski pour paire selon l'une des revendications précédentes, caractérisé en ce qu'une divergence du bord inférieur (3a') vers le haut par rapport au plan à travers les lignes droites (2) est atteinte en ce que la surface de glisse (1a) sur la section frontale est bordée sur les côtés par deux sections biseautées (4).
  5. Un ski pour paire selon la revendication 4,
    caractérisé en que les sections latérales biseautées (4) s'étendent principalement à l'extérieur des lignes droites parallèles (2).
