Definitions

  • the invention is in the field of snow gliding boards such as skis or snowboards, which are mainly used for sports and amusement purposes. It relates to a snow sliding board and a pair of skis according to the preambles of the independent claims.
  • the ski is waisted in the horizontal direction, so that it is narrower in the middle area than in the front and rear area.
  • This geometry together with different area and torsional moment of inertia, determines the ride characteristics of the ski.
  • Today's recreational skis are particularly optimized for a "carving" driving technique, in which the curves are driven on the edges, without drifting sideways.
  • the horizontal sidecut together with the self-adjusting vertical deflection predetermines the driven curve radius.
  • ski geometries are known from the prior art. So revealed the FR-804598 A a ski with an invers wedge-shaped, slightly asymmetric lower sliding surface.
  • FR-804598 A a ski with an invers wedge-shaped, slightly asymmetric lower sliding surface.
  • US-2008/272576 A is a snowboard with a bipartite shown lower sliding surface, which are arranged inclined to each other along the longitudinal axis, so that the two running surfaces abut each other at an obtuse angle.
  • the snow sliding board according to the invention has at least one torsion in its longitudinal direction in a rest position, ie without the action of external forces and moments.
  • torsion is meant here a geometric shape in which the snow sliding board is twisted or twisted along its longitudinal axis, as if a torsional moment acting on a possibly known from the prior art, unbound Snow Gliding.
  • At least one area of the snow gliding board thus has a helical shape - but with a large pitch.
  • the twist angle, d. H. the maximum angle between two said skewed straight lines is between about 0.2 ° and 60 °, for example between about 2 ° and 40 ° and preferably between about 8 ° and 20 ° in the snow sliding board according to the invention.
  • the pitch of the helical shape of a snow gliding board according to the invention is in the range between about 3 m and 3600 m, for example between about 4.5 m and 360 m, and preferably between about 9 m and 90 m.
  • the at least one torsion in the snow sliding board according to the invention does not first result from forces and moments acting on the snow sliding board when driving. Rather, the inventive snow sliding board is constructed so that the at least one twist is already present in the rest position.
  • the at least one twist can be installed specifically during the production of the snowboard, z. B. in the process of pressing the snow gliding board.
  • torsional means may be present in the snow sliding board according to the invention, by means of which torsion means can be applied and / or adjusted at least one torsion on the snow sliding board. Such torsion could z. B.
  • the variant with torsion means has the advantage that the torsion is variable, preferably by the snow sportsman himself. This results in a further possibility of variation. Of course, it is possible that while driving the already existing in the rest position torsion is temporarily changed or more torsions are temporarily introduced.
  • the torsion of the snowboard according to the invention significantly influences its driving behavior.
  • the torsion plays an essential role especially in the front and in the back of the snowboard.
  • the snow gliding board can only be twisted at the front, front and back or only at the back; Of course, several twists and twists in the middle can be present.
  • skis is understood in this document as all snow gliding boards, which are assigned to each other in pairs and are each carried on a foot of a snow sportsman. These include alpine skis such as downhill skis, carving skis, telemark skis, touring skis, short skis and twintips, as well as Nordic skis. The remaining snow gliding boards accordingly contain all sorts of snowboard types, monoskier etc.
  • the snow sliding board according to the invention enables completely new driving experiences.
  • the invention introduces the parameter "torsion" which has hitherto been disregarded in snowboard boards, which results in a variety of new variations and thus choices for the snow sports. Even a single pair of skis according to the invention offers the possibility of changing the driving characteristics by simply exchanging the left and right skis.
  • FIG. 1 a first embodiment of an inventive snow gliding board 1 is shown.
  • This snow sliding board 1 has a single torsion along its entire length. Such a torsion would arise by applying a torsional moment, which in the perspective view of FIG. 1 (a) is indicated by two arrows 7.
  • the torsion can already be built into the snow sliding board 1 during production and / or can be applied by suitable torsion means (not shown).
  • the torsion is left-handed in this embodiment, ie the snow sliding board 1 is wound from the rear in a counterclockwise direction. This is in the cross sections of Figures 1 (c) - (e) especially visible.
  • a sliding surface 3 is opposite in a rear portion 23 of the Schneegleitbrettes 1 by a first inclination angle ⁇ 1 a flat, horizontal surface 9 inclined ( Fig. 1 (c) ), in a middle region 22 approximately parallel to the base 9 (FIG. Fig. 1 (d) ) and inclined in a front region 21 by a second inclination angle ⁇ 2 with respect to the support 9 ( Fig. 1 (e) ).
  • the first inclination angle ⁇ 1 can have values between about -0.1 ° and -30 °
  • the second inclination angle ⁇ 2 assume values of between about 0.1 ° and 30 °, so that a twist angle ⁇ of about 0.2 ° to 60 ° results.
  • the inclination of the sliding surface 3 corresponds to the inclination of a straight line 5 which connects the two edges 31, 32 and is perpendicular to a longitudinal axis 4.
  • FIG. 2 (a) shows a side view of a second embodiment of an inventive snow gliding board 1, FIG. 2 (b)
  • the snow sliding board 1 has a first torsion.
  • the first torsion is right-handed in this embodiment, ie the snow sliding board 1 is wound in the front region 1, seen from behind, in a clockwise direction.
  • the snow sliding board 1 has a second, left-handed twist.
  • the first and second torsions merge into one another in a central region 22, which is intended to receive a binding. In the central region 22, therefore, the winding direction changes. Sections of the snow gliding board 1, z. B. in the central region 22, may be unbound.
  • FIG. 2 (a) In the side view of FIG. 2 (a) is the sliding surface 3 in the front area 21 and rear area 23 facing the viewer, in the central region 22 averted by the viewer.
  • the sliding surface 3 is bounded laterally by a left edge 31 and a right edge 32.
  • Figures 3-4 refer to different pairs of skis according to the invention, wherein in each case the partial figure (a) belongs to the left ski and the partial figures (b) to the right ski.
  • a longitudinal axis 4 of the ski is shown in each case.
  • the arrow indicates the preferred direction of travel, so it is located at the front end of the ski, where usually the Ski tip is.
  • individual straight lines 5 are shown, which connect the two edges 31, 32 of the sliding surface 3 and are perpendicular to the longitudinal axis 4.
  • These straight lines 5 are hereinafter referred to as "ribs", although they are merely fictitious lines without any supporting function.
  • Each rib 5 indicates for the respective position on the longitudinal axis 4, seen from behind, the inclination of the sliding surface 3 with respect to a flat, horizontal surface.
  • a rib 5 shows a cross section through the ski at the respective position on the longitudinal axis 4.
  • the representation of the Figures 2-5 be interpreted as a combination of a plan view (longitudinal axis 4) and a plurality of cross sections (ribs 5). The entirety of the ribs 5 gives an impression of the distortion of the ski.
  • FIG. 3 (a) corresponds approximately to that of FIG. 2 with her two twists.
  • the ski pair of FIG. 2 is symmetrical with respect to a symmetry plane 6 of the body of the snow sportsman. This means: Where the left ski has a right-hand twist, the right ski has a left-handed twist and vice versa. This corresponds to the first case discussed above.
  • FIG. 4 is that of FIG. 3 similar. However, the two torsions are less pronounced, so that the central region 22 substantially rests on the base.
  • FIG. 5 shows an embodiment of an antisymmetric ski, in which the right and left skis are identical to each other. This corresponds to the second case discussed above.
  • Skis have only a single torsion, as in the first embodiment of FIG. 1 the case is.
  • the torsion is right-handed on the left ski and left-handed on the right ski.
  • At least a portion of the central region 22 is preferably even or at least unbound, so that there can be attached a binding for attaching the snowboard 1 to a ski boot or to both ski boots of the snow sportsman.
  • the snow sliding board 1 can take over the other geometric features of snow gliding boards known from the prior art. These include z. B. curvatures in the vertical direction and / or a waist in the horizontal direction.
  • the cross section of the sliding surface 3 perpendicular to the longitudinal axis 4 need not be straight, but other shapes such. B. V-shape, inverted V-shape, U-shape, inverted U-shape or another curved shape. This shape may be symmetrical or asymmetrical with respect to the longitudinal axis 4.
