Definitions

  • the invention relates to a pair of skis for cross-country skiing according to the introductory part of claim 1.
  • the invention is particularly aimed at training the Pair of skis for skating or skating technology, whereby through a special design of the side shape or waist the skier should be given the opportunity to run while of running by running speed or by the runner to use the energy of the momentum caused by the pushing energy for a longer time than was possible with the usual skis.
  • Pushing off on skating skis is done by edging the ski SK over the covering edge by an edging angle ⁇ (between preferably 5 ° and 45 °) relative to the snow surface SCH, like it is schematically illustrated in Fig.1, and a simultaneous Transverse positions of the ski according to Fig. 2 at a certain deflection angle ⁇ , e.g. between 10 ° and 80 °, depending on the slope of the slope to the running direction, as well as by introducing a repulsion impulse (dependent of the running technique and the body weight of the runner).
  • ⁇ between preferably 5 ° and 45 °
  • the Sliding phase i.e. the phase in which the ski is running follows
  • the rejection phase that is Phase in which the skis are edged and turned must be kept as short as possible
  • Fig.4 are the lines GL and GR respective sliding phase of the left (GL) or right (GR) ski and with the subsequent curve AL or AR the repulsion phase of the left (AL) or right (AR) ski indicated.
  • skis with different side shape geometries required For straight-line movement (sliding phase) or driving straight would be skis with straight or concave Need page shapes according to Fig. 5 or Fig. 6 for the on the other hand, running movement of the skis (push-off phase) is convex Page shapes according to Fig. 7.
  • Skis with a concave waist have one Property picture, which requires that if you bend the ski, i.e. on the edge, it follows the concave side shape, i.e. if this ski, for example, when skating on right foot is attached, it does not refer to the outside Running direction, but pulls inwards.
  • Skis with parallel Page shape are relatively neutral, but simplify the Movement outwards compared to skis with concave Sidecut. Skis with a convex side shape automatically favor the curve towards the outside in relation to the direction of travel.
  • AT 369 273 has made a ski, namely alpine ski, known with a convex part in the middle and then there is a concave part on it.
  • This Side shape cutout is supposed to solve the task behave particularly on smooth, steep slopes improve. It is mentioned that with skis with concave Basic curve and convex superimposed curve, the highest point together with the widest part in front and the widest Place an imaginary concave side shape in the usual way Meaning gives an edge pressure distribution with a very strong pronounced pressure concentration in the area of the convex curve and achieved with very little pressure immediately before and after becomes. This is useful for alpine skis, but not for the Cross-country skating step.
  • a cross-country ski is also known from US Pat. No. 5,427,400 has a cavity in the central area in order to repel the movement the impulse on the ski to the wax zone on the underside of the ski to concentrate. Training is also shown where the ski has a concave waist on both sides, whereby this runs relatively flat in the central area; nonetheless the concave waist extends on each side of the ski from the shovel area to the end of the ski.
  • the object of the invention is through special training of Side shape or the waist of the skis the longitudinal movement of the skis stabilize so that the skis during the gliding phase pull outward less and the existing speed does not have to be canceled, but rather the momentum energy is better exploited and through conscious pressure increase and thus changing the surface pressure distribution under the ski and Concentration of weight on the middle area of the skis at the end of the sliding phase, the respective ski can be moved into the Repulsion phase is brought, whereby the runner, introduced at the same Repulsion energy, a flatter curve b or b1 (see Fig. 8) can run through and thus cover a distance W or W1 that can be bigger than the one with traditional skis distance S or S1 is covered.
  • the invention provides a pair of skis with Features of claim 1 before; advantageous embodiments are specified in the subclaims.
  • FIGS. 9 and 9A are preferred embodiments of the side waists of a cross-country ski, the convex Parts, namely central areas convex to the center line X-X of the ski KN and the widest parts H1 and H2 on the front or rear end of ski one marked with B, indicated by dashed lines Touch envelope, as shown in Fig. 9, a straight Line, or, as indicated in Fig. 9A, a convex arc can.
  • the envelope B leads from the tip-side edge region H1 to the heel edge area H2 and touches the apex of the convex central area KN.
