Open the CIPO recordAbstract From the Canadian patent
The invention provides a carriage mechanism for a glider/three-way recliner chair using relatively few link elements and which does not require positive locking linkages in order to stop the gliding movement. The carriage mechanism includes mirror-image left and right support assembly operatively interconnected by a torque tube and a main linkage sub-assembly which is capable of moving in a gliding motion relative to a flooring surface when a support assembly is in a retracted condition and moves in a motion which is parallel to the flooring surface when the support assembly is shifted to an intermediate extended condition with the parallel motion tending to stop due to gravity.

Why it's free to use
- Filed March 27, 1992 and granted May 20, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 27, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 27, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
