Open the CIPO recordAbstract From the Canadian patent
A relatively simple, safe toboggan includes a one-piece plastic body with a generally bowl-shaped front section; a waisted centre section and a rear section flaring outwardly from the centre section. Side walls extend from the centre section along each side of the rear section for supporting a seat. The seat is suspended from the side walls. The seat and/or the suspension are resilient so that most of the shock normally transmitted to a rider is absorbed thereby significantly reducing the potential for injury.

Why it's free to use
- Filed June 16, 1998 and granted November 14, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 16, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 16, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
