Abstract: The awning has an awning case (2) of sheet metal having a wider slot (11) extending father upward, compared to conventional awnings. The upper and lower edges (12, 13) of the slot are beaded. A drop-blade (8) having a similar curvature as the case, and also made of sheet metal, in rolled-up state of the awning fits closely over the slot (12) with an overlap at top and bottom. Wall brackets (5) are constructed in form of several interfitting parts and provided with a hinge connected on one end to articulated arms (9, 32, 33). The other ends of the arms are hinged to holders suspended from the drop-blade (8). When the awning is rolled-up the arms fold unobtrusively below the awning case. In the rolled-up condition the awning looks like a closed cylinder. A sealing element (83) prevents water from getting into the awning case.
