Abstract

A fixed base (11) supports a screen case (15) formed by a movable cradle (16). A cover (18) and one or more screen box carriers (17) are located between the cradle and the cover. Connectors (25) joining the constituent parts of the screen case are formed from two pantographs (27). Each part of the screen case is pivoted to the pantographs. When the pantographs are in the folded position the parts of the screen case are stacked and supported in pairs and when the pantographs are unfolded the screen case parts are spaced from each other. Each pantograph comprises two pivoting axles aligned in a direction perpendicular to the plane of the movable cradle. The lower pivoting axle is connected to the cradle and the upper pivoting axle is connected to the cover.
