Open the CIPO recordAbstract From the Canadian patent
A U-shaped outer frame (18) and a rectangular inner frame (14) form the guide framework for the lift platform (24) of a lifting apparatus. The two frames (14, 18) are each made integrally of glass-fibrereinforced plastic and have sliding articulations (20), which are moulded on integrally and are guided by runners. The, sliding articulations (20) are formed on hook-like extensions (38) of the longitudinal shanks (28, 32) of the frames (14 18), and when the lift platform (24) is in its lowered position, the sliding articulations (20) are substantially below the outline of the outer frame (18) and above the outlines of the inner frame (14).

Why it's free to use
- Filed March 10, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 10, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 10, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
