PCT No. PCT/NO95/00030 Sec. 371 Date Aug. 6, 1997 Sec. 102(e) Date Aug. 6, 1997 PCT Filed Feb. 13, 1995 PCT Pub. No. WO95/21662 PCT Pub. Date Aug. 17, 1995An Alpine pair ski (1) comprises a flat first sliding surface (2) and lateral surfaces (6a, b) provided with an approximately continuous concave sidecut between a first transition line A-A' defining the transition from a main section to a front section (3) and a second transition line E-E' defining the transition from the main section to a rear section (5), the course of a lower lateral edge (7a, b) between the transition lines A-A' and E-E' approximating a continuous curve. The sole on both sides of first sliding surface (2) comprises additional sliding surfaces (4) which extend upwards from the edge of the first sliding surface (2) to the lower lateral edges (7a, b) of the ski with an uplift (Hs) whose value at a point on the lower lateral edge (7a, b) of the ski is given by the length of the perpendicular from this point to plane of the sole. The additional sliding surfaces (4) extend in the longitudinal direction of the ski at least from the first and second transition lines A-A' and E-E' respectively towards a transversal line C-C' behind the middle of the ski and in that section of the ski where the binding is attached, the width of the ski at the line C-C' being equal to the smallest width of the ski between line A-A' and E-E'. The uplift (Hs) is in lower lateral edge (7a, b) on the additional sliding surfaces (4) substantially increases with the ski's increasing width in the direction of the lines A-A' and E-E' respectively. |
