Open the CIPO recordAbstract From the Canadian patent
This invention relates to foldable display such as the type used at exhibition and conferences. The display (10) comprises panels (11 to 14) which are arranged in an edge to edge row with support post (16) located between the butting edges. The panels can be hinged about the posts. The panels bear ferromagnetic strips (18) for locating graphic overlays (19 to 21). These overlays have hook-like extrusions or hanging strips (22) which enable them to be laterally adjusted with respect to the panels. The arrangement enables a continuous image to be displayed using the overlays without any visible join.

Why it's free to use
- Filed March 27, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 27, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 27, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
