Abstract
A snow ski has a main body with a recess located in the central portion of the top surface of the ski. The recess is adapted to receive a complementary shaped ski binding mounting plate which is bonded to an intermediate layer of viscoelastic material, which is, in turn, bonded to the main body of the ski. The ski binding mounting plate has a thickness such that the fasteners used to hold the ski binding thereon do not extend through the mounting plate into the body of the ski. The body of the ski may also include reinforcing material in the central portion of the ski containing the recess.
Claims18
A board, such as a snow ski or snowboard for use on snow or ice, the board comprising:
- (a) a longitudinally extending structural but flexing body having a core and an outer layer enclosing said core, said structural body having a top surface formed by said outer layer with an upwardly opening recess therein;
- (b) plate means for mounting a boot binding thereon, said plate means being positioned in said recess;
- (c) a viscoelastic layer positioned between said body and said plate means such that said plate means is isolated from direct contact with said body;
- and
- (d) means for attaching said body, said plate means and said viscoelastic layer together to permit flexing of said body relative to said plate means by viscoelastic deformation of said viscoelastic layer.
A snow ski comprising:
- a) a longitudinally extending structural but flexing body having a shovel portion, a waist portion and a tail portion, the body including a core and reinforcing material wrapped around and bonded to said core, said body having a top surface including a recess opening upward in said waist portion;
- b) a mounting plate adapted to fill said recess and to receive and hold a ski binding by means of at least one fastener;
- c) a viscoelastic layer positioned in said recess between said mounting plate and said body such that the viscoelastic layer isolates said mounting plate from direct contact with said body;
- and,
- d) means for bonding said viscoelastic layer to said mounting plate and said body to permit flexing of said body relative to said mounting plate by viscoelastic deformation of said viscoelastic layer.
A board, such as a snow ski or snowboard for use on snow or ice, the board comprising:
- (a) a longitudinally extending structural but flexing body having a core and an outer layer enclosing said core, said structural body having a top surface with an upwardly opening recess therein;
- (b) plate means for mounting a boot binding thereon, said plate means being adapted to be positioned in said recess;
- (c) a viscoelastic layer positioned between said body and said plate means such that said plate means is isolated from direct contact with said body;
- and
- (d) means for attaching said body, said plate means and said viscoelastic layer together to permit flexing of said body relative to said plate means by viscoelastic deformation of said viscoelastic layer;
- wherein said binding is mounted to said plate means with screw-type fasteners, and wherein said plate means has a thickness sufficient to receive said fasteners such that said fasteners do not extend into said body.
A board, such as a snow ski or snowboard for use on snow or ice, the board comprising:
- (a) a longitudinally extending structural but flexing body having a core and an outer layer enclosing said core, said structural body having a top surface with an upwardly opening recess therein;
- (b) plate means for mounting a boot binding thereon, said plate means being adapted to be positioned in said recess;
- (c) a viscoelastic layer positioned between said body and said plate means such that said plate means is isolated from direct contact with said body;
- and
- (d) means for attaching said body, said plate means and said viscoelastic layer together to permit flexing of said body relative to said plate means by viscoelastic deformation of said viscoelastic layer;
- wherein said plate means is complementarily shaped to fill said recess such that the top surface of said board comprises a smooth continuation of the top surface of the body at opposite ends of said recess.
A board, such as a snow ski or snowboard for use on snow or ice, the board comprising:
- (a) a longitudinally extending structural but flexible body having a core and an outer layer enclosing said core, said structural body having a top surface with an upwardly opening recess therein;
- (b) plate means for mounting a boot binding thereon, said plate means being adapted to be positioned in said recess;
- (c) a viscoelastic layer positioned between said body and said plate means such that said plate means is isolated from direct contact with said body;
- and
- (d) means for attaching said body, said plate means and said viscoelastic layer together to permit flexing of said body relative to said plate means by viscoelastic deformation of said viscoelastic layer;
- wherein said body includes a laterally narrowed waist portion and said recess is positioned at said waist portion, and wherein said body further includes means for reinforcing said waist portion.
