18094, Abstract, The invention relates to a ski or snowboard consisting of several layers, whose lowest layer forming the coating of the running surface is laterally bordered by steel edges. According to the invention, for the purpose of maintaining a laminar flow around the ski during action, between the coating (5) and the layered ski or snowboard body (1, 2, 3) a correspondingly dimensioned elastic insert (6) imitating the flow damping skin of a dolphin is inserted, whereby the turbulences occurring at the coating (5) of the running surface during running due to melt water are compensated. -12-

Why it's free to use
- Filed July 20, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 20, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 20, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
