A ski and a method of forming a ski. The ski includes a lower element and an upper element, each having the shape of a beam casing. The lower element has an upper surface that has either a longitudinally extending groove or a longitudinally extending projection and the upper element has a lower surface that has a groove or a projection that has a transverse cross-section that is respectively complementary to a transverse cross-section of the groove or to a transverse cross-section of the projection of the lower element, and in which the groove or projection of the lower element is nested in the projection or groove, respectively, of the upper element. Depending upon the nature of the desired response characteristics of the ski, the interior of the upper and lower elements can be selectively filled with specific materials or left empty.
A ski comprising:
A ski comprising a longitudinally extending rib, said ski formed by at least two unitarily formed longitudinally extending elements, said two unitarily formed longitudinally extending elements comprising an upper element and a lower element, wherein said upper element comprises said rib, wherein said lower element has a lower surface, wherein said upper element has a lower configuration which is shaped for complementary engagement with an upper configuration of said lower element, wherein said upper element has a longitudinally and downwardly extending projection, wherein said lower element has a longitudinally and upwardly facing groove, wherein said projection of said upper element is engaged within said groove of said lower element and extends upwardly beyond said lower element, and wherein said rib of said upper element constitutes a single rib of said ski.
A ski comprising a longitudinally extending rib, said ski formed by at least two unitarily formed longitudinally extending elements, said two unitarily formed longitudinally extending elements comprising an upper element and a lower element, wherein said upper element comprises said rib, wherein said lower element has a lower surface, wherein said upper element has a lower configuration and said lower element has an upper configuration, wherein lower configuration of said upper element is engaged with said upper configuration of said lower element, wherein each of said upper element and said lower element has a hollow interior portion, wherein said hollow interior portion of said upper element is filled with a quantity of material, and wherein said hollow interior of said lower element is empty.
A ski comprising a longitudinally extending rib, said ski formed by at least two unitarily formed longitudinally extending elements, said two unitarily formed longitudinally extending elements comprising an upper element and a lower element, wherein said upper element comprises said rib, wherein said lower element has a lower surface, wherein said upper element has a lower configuration which is shaped for complementary engagement with an upper configuration of said lower element, wherein each of said upper element and said lower element has a hollow interior portion, wherein said hollow interior portion of said lower element is filled with a quantity of material, and wherein said hollow interior of said upper element is empty.
A ski comprising a longitudinally extending rib, said ski formed by at least two unitarily formed longitudinally extending elements, said two unitarily formed longitudinally extending elements comprising an upper element and a lower element, wherein said upper element comprises said rib, wherein said lower element has a lower surface, wherein said upper element has a lower configuration which is shaped for complementary engagement with an upper configuration of said lower element, and wherein each of said upper element and said lower element has a hollow enclosed interior portion.
