Open the CIPO recordAbstract From the Canadian patent
The projection wall comprises a screen section carrying the screen and resting on two supports. The screen section can be pivoted by means of hydraulic drives about a first horizontal axis in both directions of rotation. The supports can be folded about a second horizontal axis by actuating hydraulic braces. Since the screen section can be pivoted in both directions, it is possible to yield to winds coming from the front and the back side. Furthermore the pro-, section wall can be moved to a horizontal position for assembly and disassembly. The device is easy to install and requires no anchoring.

Why it's free to use
- Filed June 17, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 17, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 17, 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.
