Abstract
A ski is constructed of a top plate separated from a bottom plate by a core made of a material elastic in shear. Each of the top plate and bottom plate is formed of at least two layers, one above the other, with one layer having a higher coefficient of linear expansion than the other. The thicknesses and positional sequence of the layers are asymmetrically arranged with respect to the longitudinal center plane of the ski. The thicknesses of the layers varies considerably between the top and bottom plates.
Claims9
Ski having a longitudinally extending central plane with a top plate located above the plane, a bottom plate located below the plane and a core extending between said top plate and said bottom plate, each of said top plate and bottom plate comprises at least two layers one above the other and each of the layers in said top plate and bottom plate being formed of materials having a different coefficient of linear expansion so that said top plate and bottom plate each comprises a larger coefficient of linear expansion layer and a smaller coefficient of linear expansion layer, wherein the improvement comprises that said larger coefficient layer and said smaller coefficient layer in said top and bottom plates are arranged asymmetrically relative to the longitudinal central plane of the ski with respect to the positional sequence of said layers and with respect to the thickness of said layers, the thickness of said larger and smaller coefficient layers in said top plate and said bottom plate being different, the thickness of said larger coefficient layer in said top plate is greater than the thickness of said larger coefficient layer in said bottom plate and the thickness of said smaller coefficient layer in said top plate is smaller than the thickness of said smaller coefficient layer in said bottom plate.
