Abstract From the Canadian patent

The invention relates to a rotary closure for a sports shoe, especially a ski shoe, in which at least one traction element co-operating with the closure element of the shoe can be wound onto or off of a pulley which can be rotated by an actuating shaft. A manually releasable locking arrangement fixes the actuating shaft in the chosen position of the closure. In the transmission connection between the actuating shaft and the pulley a releasable coupling is provided which facilitates release of the closure without it being necessary to bend down in order to actuate the locking arrangement.

Why it's free to use

  • Filed July 4, 1990 and granted October 15, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 4, 2010.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 4, 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.
