DETAILED DESCRIPTION OF EMBODIMENTS

(8) The illustrated screen coverings (1) comprise two lateral beams (11) which are arranged parallel to each other at a certain distance from each other. These beams (11) are provided at their bottom with a running rail (10).

(9) The screen coverings (1) further comprise several cross-beams (2) extending essentially perpendicularly between the lateral beams (11). The cross-beams (2) are provided at their top with typical trolleys (9) which are rollably arranged in the running rails (10) of the lateral beams (11), such that the cross-beams (2) are hung from the lateral beams (11), slidable towards each other and away from each other by rolling the trolleys (9) in the running rails (10). In the figures, only one lateral beam (11) is illustrated. At the other side of the cross-beams (2)—which is not illustrated—a similar lateral beam (11) is arranged.

(10) The cross-beams (2) are further supporting a screen (3), which is foldable between the cross-beams (2) at sliding of the cross-beams (2).

(11) A lateral gutter (4) extends essentially perpendicular to the cross-beams (2) and is arranged below the illustrated lateral side of the screen (3). The inner side wall (14) of the lateral gutter (4) is arranged at a certain distance underneath the screen (3) such that the screen (3) is foldable above the lateral gutter (4). The outer side wall (13) of the lateral gutter (4) extends beside the screen (3).

(12) In FIG. 1 it is illustrated with a screen covering (1) according to the state of the art, how precipitation which is laterally drained off the screen (3), can remain stuck to the bottom side of the screen (3) over a certain distance and then falls off the screen (3) besides the lateral gutter (4), into the area below the screen (3).

(13) In FIGS. 2-3, seen in longitudinal direction of the cross-beams (2), the screen (3) of the screen covering (1) is therefore extended beyond the cross-beams (2) at this lateral side. Below the screen (3) a drip guard (5) is fixed to the lateral side of the screen (3). This drip guard (5) extends over the full length of the lateral side of the screen (3) beside the cross-beams (2), forming a continuous border for precipitation (12) sticking on the bottom of the lateral side of the screen (3). This drip guard (5) is a flexible profile such that it can be folded together with the screen (3). The profile of the drip-guard (5) has a T-shaped cross section. The flexible band (6) thereof can be fixed to the screen (3) by sewing or heat sealing or adhesive bonding, etc. The tongue (8) thereof extends downwards, dividing the flexible band (6) in two flanges (7) at both sides of the tongue (8). Thanks to this T-shape, the drip-guard (5) is foldable with reduced risk of twisting thereof. As can be seen in FIG. 4, the tongue (8) guides precipitation (12) towards the lateral gutter (4), such that precipitation (12) is drained at the lateral side of the screen (3) into this lateral gutter (4).

(14) In FIG. 5, an alternative embodiment of a screen covering (1) according to the invention is sketched. Seen in longitudinal direction of the cross-beams (2), the screen (3) of the screen covering (1) is extended beyond the cross-beams (2) at the illustrated lateral side and extends up to the outer side wall (13) of the lateral gutter (14), which is not further illustrated. This outer side wall (13) forces the extension (5) of the screen (3) to extend downwards such that a drip guard (5) is formed as an integral part of the screen (3). As this drip guard (5) extends up to the outer side wall (13) of the lateral gutter (14), precipitation (12) which is drained off at this lateral side, will stick to this outer side wall (13) due to the adhesive force thereof and trickle downwards along this outer side wall (13) into the lateral gutter (14).
