Abstract

Abstract A ski with a ski body comprising a core, an upper and a lower reinforcing face, wherein at least one of the reinforcing faces comprises a profiled metal sheet having a U-shaped recess between lateral legs, the back of said recess being directed toward the core, and wherein strips of elastic-viscous material are arranged between the lateral legs of the profiled metal sheet and the core.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 145 words
A ski comprising a ski body formed with a lower snow-engaging face and an upper face each formed by respective layers, a core within said body between said layers and extending over substantially the entire width of the body, at least one profiled metal sheet disposed between a respective one of said layers and said core, said profiled metal sheet having a U-shaped recess opening away from said core and having a bottom defined by a back portion of said profiled sheet, said profiled sheet further comprising a pair of lateral flanges spaced from said back of said profiled sheet, said back of said profiled sheet bearing against said core and said flanges overhanging said core to define spaces along opposite edges of said core between said core and said flanges, and respective viscous-elastic strips received in said spaces for damping vibration of said ski.
Claim 2
Dependent Claim 145 words
A ski comprising a ski body formed with a lower snow-engaging face and an upper face each formed by respective layers, a core within said body between said layers and extending over substantially the entire width of the body, at least one profiled metal sheet disposed between a respective one of said layers and said core, said profiled metal sheet having a U-shaped recess opening away from said core and having a bottom defined by a back portion of said profiled sheet, said profiled sheet further comprising a pair of lateral flanges spaced from said back of said profiled sheet, said back of said profiled sheet bearing against said core and said flanges overhanging said core to define spaces along opposite edges of said core between said core and said flanges, and respective viscous-elastic strips received in said spaces for damping vibration of said ski.
Claim 3
Dependent Claim 65 words
The ski defined in claim 1 wherein a respective profiled sheet is provided between each of said layers of said core and each such profiled sheet has a back bearing against said core and flanges defining said spaces along opposite edges of said core between said core and the respective flanges, such viscous-elastic strips being received in the spaces of both of said profiled sheets.
Claim 4
Dependent Claim 19 words
The ski defined in claim 1 or claim 2 wherein said strips bridge between said flanges and said core.
Claim 5
Dependent Claim 21 words
The ski defined in claim 1 or claim 2 wherein said strips are of the same width as the respective flanges.
Claim 6
Dependent Claim 27 words
The ski defined in claim 1 or claim 2 wherein said spaces open freely laterally of the ski and the edges of said strips are laterally unconfined.
Claim 7
Dependent Claim 26 words
The ski defined in claim 1 or claim 2 wherein said strips have thicknesses equal substantially to the depth of the recess of the respective sheet.
Claim 8
Dependent Claim 19 words
The ski defined in claim 1 or claim 2, further comprising a solid material filling each of said recesses.
Claim 9
Dependent Claim 14 words
The ski defined in claim 7 wherein said solid material is a reinforced plastic.
Claim 10
Dependent Claim 17 words
The ski defined in claim 8 wherein the reinforced plastic is a plastic reinforced with glass rovings.
Claim 11
Dependent Claim 24 words
The ski defined in claim 8 wherein said solid material is a sheet having a thickness equal to the depth of the respective recess.
