Abstract: The invention relates to a roller shutter (10, 32, 42, 51) for opening and closing a doorway having a door leaf (11) and side rails (17) for guiding the door leaf (11), and having a coiling device (14) for selectively rolling up the door leaf (11) for opening the doorway and unrolling the door leaf (11) for closing the doorway. For reducing or avoiding the risk of creating a polygon effect and for providing a roller shutter (10, 32, 42, 51) comprising a door leaf having rigid shutter elements with an increased height and/or with the possibility of applying an increased speed for opening and/or closing the door leaf the roller shutter (10, 32, 42, 51) is characterized in that a separate guiding device (21, 33, 43) is provided for guiding the door leaf (11) in the area between the side rail (17) and the coiling device (14), wherein the guiding device (21, 33, 43) is arranged to adjust to an increasing diameter and to a decreasing diameter of the coiling device (14).

Abstract: The invention relates to a roller shutter for opening and closing a doorway (12) having a door blade (11), the door blade (11) comprises several rigid shutter elements (13) which are hinged with each other, the shutter elements (13) are guided by side rails (18) at opposed sides of the doorway (12), wherein each shutter element (13) provides an end piece (19) at each horizontally spaced end of the shutter element (13) for spacing layers of rolled up shutter elements (13) apart from each other, each end piece (19) has at least one concave section (27) for coiling the end pieces (19) on a coiling device (14) and/or in layers on top of each other. For reducing the risk of weakening a connection between the end piece (19) and the shutter element (13), for reducing noise and/or vibrations during the opening and/or closing of the door way and/or to increase the stability of the roller shutter the roller shutter (10) is characterized in that at least some of the end pieces (19) having at least one plane gliding section (28), the plane gliding section (28) is arranged for interacting with a slide guide (36) of the side rail (18) for leading the end pieces (19) into and/or out of the side rails (18).

Abstract: The invention relates to a sealing device (11, 35, 41) for sealing a gap (32) between a lintel (30) and a roller shutter (10, 34, 40). The sealing device (11, 35, 41) has a sealing means (23) for arranging at the upper end of a top shutter element (24) of the roller shutter (10, 34, 40). For covering a gap (32) in a functional and/or cost-effective way between a lintel (30) and a roller shutter (10, 34, 40), preferably in case of a completely unrolled door blade (12), the sealing device (11, 35, 41) is characterized in that a swivel mechanism (25, 37, 43) is provided for swivelling the sealing means (23) from a sealing position into a winding position and from a winding position into a sealing position.

Abstract: The invention relates to an overhead door for covering a door opening comprising a door blade (11) with a plurality of panels (17), said door blade (11) being movable between a vertical, closed position and a horizontal, opened or overhead position within a side frame (12) comprising double-sided a vertical track (13) and a horizontal track (14), connected by a connecting portion (15), respectively, and with a belt (20) or a chain associated with one side each of the said side frame (12) to lift the panels (17) from said vertical position to said horizontal position. To develop the stated overhead door in a way that the advantages of a high speed rollup door and an overhead door are combined, to offer an overhead door with a low space requirement, low maintenance requirements and a high speed closing possibility, the stated overhead door comprises driving means (27) for simultaneously driving a plurality of said panels (17).
