ABSTRACT OF THE DISCLOSURE The projection wall comprises a screen sec- tion 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.
