Problems solved by technology

When the tip scrapes the snow in this way, it disrupts the skier's movement by reducing his efficiency and, in certain cases, even risks causing him to fall.

Embodiment Construction

[0019] The front of the cross-country ski (1) shown in FIG. 1 lies in a horizontal plane H. The front contact line (2) illustrated in FIG. 1 corresponds to the longitudinal level of the ski where the sole (3) ceases to be in contact with the horizontal plane H. The tip starts beyond this front contact line (2). This tip is curved upward as far as its end (5).

[0020] According to the invention, and as illustrated in FIG. 2, the tip (4) has two inflexion points (6, 7) located on either side of the median longitudinal plane (8). More precisely, these inflexion points occur on the projection of the side line of the tip (4) over the horizontal plane on which the sole (3) lies.

[0021] The inflexion point is understood in its geometrical definition as the point (6, 7) where the side line of the tip (4) crosses its tangent (15). Thus, to the rear of the inflexion point (6, 7), the portion (10, 11) of the side line has a curve oriented toward the inside of the ski. Conversely, forward of this ...

Abstract

Cross-country ski (1) having a tip (4) curved upward, extending beyond the front contact line (2), wherein the projection of the side line of the tip (4) of the ski over a horizontal plane has an inflexion point (6, 7) located forward of the front contact line (2), at least on one side of the ski.

Description

[0001] The invention relates to the field of gliding sports and, more particularly, to that of cross-country skiing. More precisely, it relates to a cross-country ski having a tip that is optimized and, more precisely, "narrowed" in comparison to conventional cross-country skis.Prior Art[0002] In a known manner, a cross-country ski has a front end forming a tip. This tip forms an upwardly curved zone, the width of which decreases toward its end. This tip is curved upward to enable the ski to be on top of the snow and to overcome obstacles and differences in level that exist on the gliding trail.[0003] Generally speaking, this tip is considered to start forward of a transverse line defined in standard fashion as the front contact line.[0004] In cross-country skiing specifically, using the skating technique, the skier performs a movement in which the bearing forces are taken up while the ski is oriented obliquely relative to the direction of displacement.[0005] After having exerted a ...
