Abstract

On a front section, an Alpine style ski has a greatly increased width, and the lower edges (3a') of the sides (3a) are gradually raised on this section so that they diverge upwards in relation to each of two imaginary, straight, parallel lines (2) which constitute extensions of the lower edges (3') of the sides (3) of the rest of the main body.

Claims9

Dependent claims

A ski comprising:

a main body having a top side and a bottom side, the main body including a body segment and an upwardly bent segment, the bottom side of the body segment including a substantially flat sliding surface defining a plane;
an upturned tip, the tip meeting the upwardly bent segment of the main body at a first transition;
a second transition along the main body;
the main body and the tip including oppositely disposed first and second sides, each of the first and second sides including oppositely disposed upper and lower edges, the upper and lower edges extending substantially along the length of the ski;
a longitudinal axis extending along the length of the main body and the tip;
the first and second sides along the main body being curved;
the first and second sides of the tip including outwardly extending portions, and the first and second sides of the main body including outwardly extending portions, the outwardly extending portions on the main body extend along at least part of the upwardly bent segment, the outwardly extending portions on the main body tapering outward from the second transition to the first transition, such that the outwardly extending portions of the main body join the outwardly extending portions of the tip at the first transition;
the first transition having a width approximately 15% to 70% greater than the width of the second transition;
the outwardly extending portions of the tip and the outwardly extending portions of the main body forming side sections, each of the side sections including an upper surface and a lower surface, the upper surface extending to the upper edges of the respective first and second sides, the lower surface diverging upwards and extending to the lower edges of the respective first and second sides, and outwards in relation to the longitudinal axis of the ski, the vertical distance between the lower edges of the first and second sides at the first transition and the plane of the sliding surface being at least 10% of the increase in width between the first transition and the second transition.
