Three-in-one alpine ski

Abstract

An alpine ski that facilitates carving for beginner and intermediate skiers by having at its bottom surface two shallow wedge-shaped indentations, one at each edge, so that it is functionally equivalent to three narrow skis fused into one, the left-hand one of them being used on left turns, the right-hand one of them being used on right turns, all three of them being used when the ski is flat on the snow. Also, a pair of alpine skis that facilitate carving for advanced skiers, the two skis being mirror images of each other, each ski having on its bottom surface one such indentation.

1 . An alpine ski constructed as conventional alpine skis are, with the difference that its bottom surface is shaped to define two shallow wedge-shaped indentations, each indentation extending along at least the majority of the length of the ski, each indentation being spaced apart from the corresponding ski edge by at most 0.25 inches, each indentation extending in the transverse direction at an angle relative to the bottom surface that does not exceed 10 degrees, each indentation having width that does not exceed 1.5 inches, a width that along the length of the ski can be constant or varying. 
   
   
       2 . An alpine ski pair, constructed as conventional alpine skis are, with the difference that the bottom surface of each ski is shaped to define one shallow wedge-shaped indentation, so that the two skis are mirror images of each other, said indentation extending along at least the majority of the length of the ski, said indentation being spaced apart from the corresponding ski edge by at most 0.25 inches, said indentation extending in the transverse direction at an angle relative to the bottom surface that does not exceed 10 degrees, said indentation having width that does not exceed 1.5 inches, a width that along the length of the ski can be constant or varying.
