Title:
METHOD OF MAKING A SNOWBOARD HAVING IMPROVED TURNING PERFORMANCE
Document Type and Number:
WIPO Patent Application WO2000048693
Kind Code:
B1
Abstract:
A method of making a snowboard (10) or ski so that the bottom surface (18) of the snowboard (10) or ski is capable of bowing into a desired longitudinal curvature, with a circular arc being the preferred shape, in order to enable a "perfect" turn to be carved. The method comprises the steps of selecting a desired longitudinal curvature of the snowboard during turns, determining the desired curvature of the snowboard at a plurality of cross-sectional portions thereof in order to achieve the desired curvature, and selecting the cross-sectional area moments of inertia at each of the plurality of cross-sections to provide the desired curvature. The thickness of the core (38) of the snowboard (10) is the preferred design variable. The center section (30) of a snowboard (10) designed in accordance with this method has smaller average area moment of inertia than one or both of the front and rear mounting zones (24 and 28). Snowboards designed and constructed in accordance with this method exhibit improved turning performance, particularly in sharp, tight turns.
