The invention relates to a covering device (10) for surfaces, windows, doors and similar openings (11) or for the areas or parts of said surfaces, comprising at least one covering element (16) consisting of movable element parts (17), which are connected in a zigzag manner, can be folded and unfolded in a fan-like manner, wherein said element parts are unfoldable in such a way that a substantially flat covering element (16) is formed and are foldable in such a way that a stack is formed. Said at least one covering element (16) comprises two edge parts, which are independent or formed by the parts of the covering element (16) in such a way that an angle is formed therebetween in the unfolded position. The element parts (17) are substantially brought together in a common area (21) just as edge parts. The element parts (17) are fastened together in the form of a bloc of layers (60) in said common area (21). Said bloc of layers (60) is embodied in the form of a freely movable part which is not rigidly fixed to the two edge parts. |
