Definitions

  • the invention relates to a snow gliding board, in particular ski according to Preamble of claim 1.
  • Sliding boards and in particular skis are known in various designs. These snow sliding boards are also known in an embodiment in which the long sides or the edges on these long sides of the sliding board each have a concave course in a partial area ( Sidecuts ”) in the form of so-called Carving sidewalls ".
  • the object of the invention is to show a snow sliding board, which is essential has improved driving characteristics.
  • a Snow gliding board in particular ski designed according to claim 1.
  • the course of the respective side pull (hereinafter also Sidecut) taking into account the actual bending line of the respective sliding board selected such that the upturned ski (upturn, for example, about 20 to 40 °) with the corresponding edge along the entire length of the concave sidecut pressure distribution on the surface is as even as possible.
  • the ski 1 shown in FIGS. 1 and 2 consists of a ski body which is under Use of the usual ski building materials is made. With 2 is the front one Ski end with the usual upward curved ski shovel and with 3 the rear one Designated ski end. The ski center or the binding area is indicated by 4.
  • the ski 1 is on its two long sides 5 and 6 in the partial areas 5 'and 6' there concave, in such a way that in these areas on the underside of the ski 7 or on the tread there provided steel edges with their outer edges 8 a concave course exhibit or form concave sidecuts, such as those used by carving skis as carving sidewalls are known per se.
  • the ski 1 is on the underside 7 in a known manner curved several times so that the ski underside 7 at least in the area of the front Skiendes 2 is slightly convex and slightly concave in the middle of the ski 1.
  • the thickness of the ski 1 varies over the length.
  • a simulated loading of the ski 1 in which the ski on a front support 9 in Area of the ski tip 2 or the shovel there and on a rear Bearing 10 rests in the region of the rear end 3 and with a force K in the Ski center 4 is loaded, there is a bending line for the ski body, which in FIG. 3 is shown schematically at 11 and clearly from a curve line 12 deviates.
  • the load K is, for example, 30 kg.
  • the supports 9 and 10, on which the Ski body 1 with the underside 7 rests are each at a certain distance from the front ski end 2 or from the rear ski end 3 to the ski center 4 offset provided, namely where the ski body or ski 1 due to Curvature of the underside 7 when skiing the ski 1 on the ground or snow lies on.
  • FIG. 3 shows the circular arc line 12, the radius R K of which is selected such that the circular arc line 12 touches the actual curve line 11 in the area of the ski center 4 and cuts on the two supports 9 and 10.
  • the bending line 11 and the circular arc line 12 are each curved toward the same side.
  • Fig. 3 further shows that in the illustrated embodiment of the ski is more curved due to the greater thickness and greater rigidity of the ski 1 in the ski center 4 outside the ski center 4 by the load K (smaller radius of curvature) than this corresponds to the circular arc line 12 .
  • Fig. 4 with 13 the curved course of the sidecut or sidecut line is shown, which the outer edge 8 of a steel edge in plan view of the unloaded ski 1, ie in the projection onto an imaginary plane E, which is parallel to the Longitudinal axis L of the ski body 1 and also parallel to the transverse axis Q intersecting this longitudinal axis in the ski center 4 at right angles.
  • a circular arc line is shown in FIG. 4 with 14, which touches the sidecut line 13 in a first reference point, which corresponds to the ski center 4, and the sidecut line 13 in further reference points, which in FIG. 4 with 15 and 16 are labeled.
  • These reference points 15 and 16 correspond to the beginning or the end of the respective concave or waisted region 5 'or 6' of the long sides 5 and 6.
  • the sidecut line 13 and the circular arc line 14 are each curved toward the common side.
  • the radius of the circular arc 14 is designated R S.
  • ⁇ S ⁇ D / y
  • y is a constant or a ratio value greater than 10.
  • y is also a function of x.
  • the value y is in any case chosen so that the sidecut line 13 from the circular arc line 14 deviates in such a way that when edged (edging ⁇ about 20 to 40 ° - FIG. 5) and loaded ski the corresponding edge 8 in the waisted area 5 'or 6' or the modified sidecut line 13 over the entire length of this area and with pressure distribution as uniform as possible rests on the substrate 18.
  • edged edging ⁇ about 20 to 40 ° - FIG. 5
  • This one for the optimal driving condition then turns to that described above Formation of the sidecut line 13 by bending the upturned ski accordingly with different loads.
  • the modified sidecut line 13 is therefore in FIG. 4 taking into account the led through the ski center 4 and the reference points 15 and 16 Circular arc line 14 formed in that each point 17 'on the circular arc line 14 outwards by the amount ⁇ S, i.e. to the convex side of this circular arc line 14 is shifted, namely on the radius RS.
  • ⁇ S is taken into account the deviation ⁇ D of the actual bending line 11 from the theoretical circular arc-shaped bending line 12, which is the above described the edged and loaded ski 1 lies evenly on the base 18 results.
  • each point 17 is formed on the sidecut line 13 in that the radius R S of the circular arc line 14 is each extended by the amount ⁇ S, that is to say in the course of the bending line 11 shown in FIG. 3, with respect to the circular arc line 12 the sidecut line 13 is closer to the ski center or longitudinal axis L than the circular arc line 14.
  • the sidecut line 13 is closer to the axis L than the circular arc line 14 and further in the other section.
  • Figure 5 shows a very simplified representation of a cross section through the upturned skis.
  • the upstand is indicated by the angle ⁇ .
  • Ski 1 is lying with an edge 8, which has the course of the sidecut line 13, on the substrate 18 on.
  • ⁇ D and ⁇ S are respectively determined or determined radially. In principle, it is of course also possible to determine and determine these differences in the axial directions parallel to an imaginary transverse plane of the ski, including the transverse axis Q, as indicated in FIGS. 6 and 7 by ⁇ D 'and ⁇ S'.
