The wheel chock can be releaseably secured to the floor in close proximity to a wheel in use to form a chock which will bear against the wheel to prevent movement of the wheel.

Why it's free to use
- Filed December 1, 1989 and granted July 6, 1993. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 1, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 1, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
