Definitions

  • the invention relates to a ski with a rotatable rod arranged in its longitudinal direction and having different bending behavior in different angular positions.
  • Such a ski is known from DE-OS 14 78 168.
  • This known ski has an embedded or attached, rotatable rod with a flat, rectangular cross section, which is flexible in the direction perpendicular to the broad sides, but is essentially rigid in the direction perpendicular to the narrow sides. By turning this rod, the ski can be adjusted to be harder or softer and thus adapted to the skill of the skier and the
  • a rod of this type forces the ski into a completely straight shape in the harder or stiffer setting, while in general a certain curvature of the ski in order to adapt to uneven terrain and for better edge engagement, especially on icy slopes and on steep slopes is preferred.
  • This object is achieved in that the rod is preloaded in an arc.
  • the rod can have a round cross section and can be arranged in a corresponding tubular guide channel in the interior of the ski, but can also be attached, for example, to the surface of the ski in suitable bearings.
  • the guide channel can moreover have a flat box shape, the height of which essentially corresponds to the diameter of the rod, the width of which, however, allows the rod to be held in a relaxed manner when the rod is preloaded laterally.
  • the rod can be made of a glass fiber or carbon fiber material or Keflar.
  • a hand lever protruding from the ski can be connected to the rod at a suitable point, by means of which the rod can be rotated.
  • Fig. 1 is a longitudinal section through a ski according to the invention
  • Fig. 2 shows a rod for adjusting the
  • FIG. 4 is a cross section through another embodiment of a ski according to the invention.
  • a ski 10 shown schematically in longitudinal section in FIG. 1 is traversed in the longitudinal direction by a tubular guide channel 12 which is in the vicinity of the front
  • Tip 14 of the ski begins and extends to its rear end 16.
  • the guide channel 12 emerges from the ski 10 at the rear end 16.
  • a cylindrical rod 18 which is pre-shaped in a relaxed position in an arcuate manner, as shown in FIG. 2.
  • This rod can consist of a highly elastic, dimensionally stable material based on glass fiber or carbon fiber.
  • the rod 18 is rotatable in the guide channel 12.
  • the guide channel can consist, for example, of a PVC tube embedded in the ski.
  • the rotation of the rod 18 can be carried out with the aid of a handle lever 20 on the
  • Rod 18 is attached and at a suitable location from the ski exit.
  • a handwheel, a hexagon head or the like can also be provided on the rear end 16 of the ski on the end of the rod 18 emerging there.
  • the rod 18 has an arcuate bias, as shown in FIG. 2. Depending on the rotational position of the rod, the front and rear ends of the ski are pressed down, raised, or left essentially unaffected.
  • the rod 18 can be pulled out of the guide channel 12 and can therefore be replaced, so that rods with different physical properties can be used as desired.
  • FIG. 3 is an enlarged rear view of the ski of FIG. 1.
  • the rear end of the rod 18 can be seen with the handle lever 20.
  • Fig. 4 is a cross section through a ski according to another embodiment of the invention.
  • the guide channel denoted by 22 has a flat, horizontal box shape, at least in the central region of the ski 10, so that the rod 18 is essentially in the relaxed position in the horizontal position of the bow shape and a regression of the bow shape is avoided by permanent exposure.
  • the rod does not necessarily have to lie in the longitudinal central axis of the ski. For example, it can make sense to move it towards the inner edge of the ski, since the inner edges of the skis are primarily used for edging on ice with the usual, predominant load on the valley-side ski.
  • ski is primarily only torsionally rigid, but is only slightly rigid. In this case the bending stiffness results almost exclusively from the position of the rotatable rod.
  • the rod can have a smaller diameter at the ends than in the middle.
  • the transition to smaller diameters can take place continuously or in stages.
  • the wall thickness can decrease towards the ends.
  • the rod can also be prestressed in the middle with a narrower bending radius than in the ends. In any case, the force applied by the rod should be greater in the middle than at the ends of the ski.
  • the rod should have a high pre-deformation with a small rod cross-section rather than with a high intrinsic stiffness, small pre-deformation, so that the rigidity of the ski and the vibration behavior remain independent of the position of the rod.
  • it can also be advantageous to provide a small pre-deformation in the case of a high inherent rigidity of the rod, so that the ski rigidity can be varied in addition to the surface pressure distribution.
  • skis When viewed from the top, skis have a waist curve. When the skier edges, he automatically runs an arc with the radius of the waist line. If the radius of the waist is not constant, the radius driven by the runner can be changed by changing the rod position and thus the resulting contact position of the edge.
  • the ski itself can be flexible or only torsionally rigid and get the bending stiffness only from the bar. This also applies to the preload.
  • the running surface can have a lower gliding ability in the middle area than at the ends, so that a certain braking effect is achieved in steep terrain with low pretension by the rod.
