Abstract From the Canadian patent

This invention, in one aspect, relates to a ski and a spatula attachment, reducing the spatula vibrations without affecting other ski or spatula characteristics. The damping is obtained through a dissipative spatula to ski linkage. The various embodiments described achieve dissipative action through frictionally slidably engaged surfaces. Another aspect of this invention relates to a linkage forming an integral part of a ski, wherein the spatula vibrational, torsional and flex characteristics are substantially determined by the linkage as described in the various embodiments.

Why it's free to use

  • Filed February 4, 1991 and granted January 11, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 4, 2011.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 4, 2013.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
