• Fig. 35 shows the isometry of an embodiment variant of the screen or a screen group. It can be clearly seen that several umbrellas can be put together in loosely connected rows. In the example shown, umbrellas are used that only have high points (34) in the middle of the common edges, so that any rainwater that may occur is drained outward primarily through the corners formed as low points (35).

• the low arms (32) are in turn pulled upwards by the sail edges (11) which connect high points (34) and low points (35). Due to the tensile strength of the sail surface (10) in the connecting line between the umbrella axis (1) and the low point (35), a self-contained balance of forces is created, which stabilizes the umbrella. In this case, the sail area (10) takes on static properties due to sewn-on webbing straps, integrated pulling ropes, etc.

It is particularly noteworthy that the closing of the screen by raising the sleeve (25) also works with tables below it, because the sleeve (25) also moves the arms (30) upwards. When opened, they are moved down again and ensure good sun protection due to the short distance to the floor.
