A body receives the hinge pin in order to rotate substantially perpendicular to the axis of the hinge pin. An adjustable mechanism extends from the body and rests against the doorway.

Why it's free to use
- Filed March 11, 1991 and granted November 14, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 11, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 11, 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.
