Open the CIPO recordAbstract From the Canadian patent
An improved adjustable center door pivot assembly is disclosed which can be mounted to a threshold without the need for a separate mounting bracket. The adjustable center pivot assembly permits the height of the pivot spindle to be adjusted without removing the door. Further the height of the adjustable center pivot assembly which projects above the threshold is sufficiently short that the pivot assembly can be used with a standard door having a standard 21/32" web.

Why it's free to use
- Filed June 2, 1993 and granted February 18, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 2, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 2, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
