SKI - ALPINE

摘要

A ski, particularly an Alpine ski, where the maximum height (radius of curvature) of the bottom camber is in the rearward portion of the ski behind the centerline of the boot placement; and the waist (minimum width of side camber) of the ski is ahead of the centerline of the boot placement such that the ski width is increasing at this centerline position. BACKGROUND OF THE INVENTION This invention relates to an improved ski design and more particularly to improve the efficiency of Downhill skis, Giant Slalom skis, Slalom skis and Recreational Alpine skis. The present ski design has developed over the years. The two key factors which affect the performance of a ski are the "camber" which is the upwardly bowed bottom surface and the "side camber" or "side cut" in which the forward end and rear end of the ski are wider then the center or waist of the ski. Clement, US Patent No. 2,258,046 issued Oct.7, 1941 illustrates an early ski which incorporates camber. Beerli in Patent 2,210,794 issued June 6, 1950 illustrates the concept of "side camber".
