Definitions
- the kick off on skating skis is done by a edging of the ski SK over the base edge by an edging angle beta between preferably 5 and 45 ° with respect to the snow surface SCH. as schematically illustrated in Fig. 1 and simultaneous b transverse positioning of the ski according to Fig. 2 at a certain deflection angle alpha, e.g. between 10 and 80 ° depending on the slope of the slope to the running direction and c by introducing a push-off impulse (depending on the running technique and
- the sliding direction of the ski coincides with the running direction of the runner, as is shown schematically in FIG. 3.
- Hiebei is indicated by arrow A, the direction in Figs. 2 and 3.
- the sliding phase that is the phase in which the ski follows the direction of travel
- the push-off phase that is the phase in which the ski has to be edged and turned
- Fig. 4 Therein are the respective lines GL and GR
- the sliding phase of the left and right skis and the subsequent curve AL and AR indicate the repulsion phase of the left and right skis.
- skis have either a parallel waist or a concave waist, in which the ski ends and the ski tips are wider than the center of the ski. Furthermore, skis are known in particular for the skating technique, which have a convex waist, in which the ski width is larger in the middle than in the front and rear area. Finally, skis are known which have a convex or parallel waist in a certain area and are designed swept towards the tip. Skis with a concave waist have a property profile, which requires that. if you upturn the ski, i.e. on the edge, it follows the concave side shape, i.e. if, for example, this ski is attached to the right foot when skating, it does not pull outwards in relation to the running direction, but inwards. Skis with a parallel side shape are relatively neutral, but make it easier to move outwards compared to skis with a concave waist. Skis with a convex side shape automatically favor the curve towards the outside in relation to the running direction.
- the aim is that the ski pulls outwards from the running direction in order to maintain a certain transverse position in relation to the running direction so that the runner is on the outer ski repel and switch to the other step.
- This technique favors convex or parallel side shapes more than concave side shapes, which have an opposite effect.
- the disadvantage of convex side shapes is that the ski as soon as it is upturned, automatically draws into the curve according to the waist.
- the ski automatically pulls along the waistline into a curve labeled a to an angle that depends on the slope of the track, because the greater the slope Slope of the track, a correspondingly larger deflection away from the direction of travel must be taken in order to be able to perform a kick.
- the runner in the known ski must disadvantageously abort his remaining speed in order not to get too far from the longitudinal direction.
- AT 369 273 is a ski. preferably an alpine ski has become known, in which there is probably a convex part in the central region and then a concave part.
- This side shape cutout is intended to solve the task of improving the behavior of alpine skiers, especially on smooth, steep slopes.
- the object of the invention is to stabilize the longitudinal movement of the ski by a special design of the side shape or the waist of the ski, so that the ski pulls outward less during the sliding phase and the existing speed does not have to be interrupted.
- the swing energy is better used and by conscious pressure increase and thus change of the surface pressure distribution under the ski and concentration of the weight on the middle area of the ski at the end of the sliding phase of the ski is brought into the push-off phase in a shorter time, whereby the runner, introduced at the same Repulsion energy, can go through a flatter curve b or b 1 and thus can cover a distance W or Wl that is greater than the distance S or S 1 covered with the conventional skis.
- FIG. 9 shows a preferred embodiment of the side waists of a cross-country ski, the convex parts of which, that is to say the convex middle parts KN and the widest parts H1 and H2 on the tip-side contact edge or heel-side contact edge touch an envelope denoted by B, indicated by dashed lines, which, as shown, may be a straight line or, as indicated in FIG. 9A, a convex arc.
- the envelope leads from the tip-side edge area Hl to the heel edge area H2 and touches the apex of the central, convex part KN.
- the pressure on the ski is increased and the ski is edged, as shown in FIG. 1. This causes the contact areas to migrate to the center of the ski.
- the ski is now brought outwards into the push-off position.
- the corresponding contact line, shown in FIG. 11, with a load of, for example, the entire body weight up to 1 Vi of the body weight is indicated by Kl and the direction of the ski is indicated by arrow A2.
- the decisive factor for this process described above is the interplay between the bending stiffness curve, side shape and edge of the ski.
