SKATE-STYLE SKI Russian patent published in 1999 - IPC

FIELD: sports equipment. SUBSTANCE: ski has front part with longitudinal continuous projection offset to inner end of ski, strip embedded into projection and made from wear-resistant material, such as titanium. Inner convex part of sliding surface is positioned behind projection and inclined to horizontal surface. Inner convex part is provided with longitudinal continuous protrusions. The whole of convex surface or only protrusions are made from high-strength material, such as high-strength plastics or titanium, or strip of high-strength material, such as titanium, is embedded into protrusions. Such construction allows ski to be inclined at lateral abutment (thrust) against ski track, with main projection initially coming into engagement with ski track and, at the final stage of thrust, protrusions on convex surface of inner part of sliding surface. As a result, ski track adhesion coefficient is increased at the final stage of trust. EFFECT: increased efficiency, simplified construction and increased speed of motion. 3 cl, 4 dwg
