Ski with U shaped shell with integrated top flange - has bottom flange, with hollow interior to shell containing foam plastic core

摘要

The top (27) and/or bottom (26) side of the ski's core (6) is joined by plastic (33) filling the intermediate cavities (34, 35) to a top and/or bottom flange (3, 4), preferably made of elastomeric foam. The ski core and the top and/or bottom flange are spaced apart by support elements (28) distributed over the top and/or bottom sides (27, 26), to form lengthwise or crosswise ducts (30, 39) opening into the intermediate cavities. The shell's (2) facing inner surfaces and those of the bottom flange or tread surfaces (7) form a constantly tapering compartment (45, 46) pointing towards the tread surface's outer surface (43) facing away from the ski, as far as a limit (44) separating a contact surface from the inner surface. ADVANTAGE - The ski's side walls withstand high stress and impact.
