Abstract
A sports board for surfing, snow sledding, and other sports, has a shaped polyethylene foam core to which a polyethylene film/polyethylene foam sheet laminate is heat laminated over substantially all the surfaces of the core. Frictional resistance between the board and surfaces on which the board is used is reduced, and the slick film outer skin provides an impervious outer surface to the board which resists puncturing and water absorption by the board.
Claims9
A soft sports board for skimming over water or snow comprising a preformed, preshaped foam core, and polyethylene film means comprising a sheet of polyethylene film laminated to a sheet of polyethylene foam, said polyethylene foam sheet having a greater density than said foam core, said polyethylene film means being laminated to outer surfaces of the preformed, preshaped foam core of said board to substantially completely cover the outer surfaces of the core, wherein the foam sheet is laminated to the foam core and the film sheet provides an outer glossy, impervious polyethylene film surface for reducing friction and decreasing water absorption of the board.
A soft sports board for skimming over water or snow comprising a preformed, preshaped polyethylene foam core, and a laminate comprising a polyethylene foam sheet of greater density than the foam core heat laminated to a polyethylene film sheet, said laminate comprising a foam face and a film face, the foam face of said laminate being heat laminated to the preformed, preshaped polyethylene foam core and the film face of said laminate forming a slick outer skin for said board, wherein the core is substantially covered by sheets of the laminate.
A method for making a soft shaped sports board for skimming over water or snow comprising:
- heat laminating a polyethylene film to a polyethylene foam sheet to form a film/foam laminate having a foam surface and a film surface, and
- heat laminating the foam surface of the film/foam laminate to a preformed, preshaped polyethylene foam core having a lower density than that of the polyethylene foam sheet, whereby the film surface provides a glossy outer surface for the board.
