Abstract: A high-speed rolling gate comprising a door leaf in the form of a flexible curtain, lateral guides in which lateral edges of the door leaf are received, and a drive which generates a driving force for driving the door leaf, wherein the door leaf has an elastically designed terminating element on a forward edge which is tensioned between the lateral guides by means of laterally applied transverse force components. The driving force of the drive engages on the terminating element of the door leaf and provides the laterally applied transverse force components for tensioning the terminating element of the door leaf and a tension force component substantially directed in the movement direction of the door leaf for closing the door leaf.

Abstract: The invention relates to a rolling gate (100), in particular a high-speed rolling gate, comprising: a door leaf (110) in the form of a flexible curtain, lateral guides in which lateral edges of the door leaf (110) are received, and a drive (140) which generates a driving force for driving the door leaf (110), wherein the door leaf (110) has an elastically designed terminating element (112) on a forward edge which is tensioned between the lateral guides by means of laterally applied transverse force components. Said rolling gate (100) is in particular characterized in that the driving force of the drive (140) engages on the terminating element (112) of the door leaf (110) and thus provides the laterally applied transverse force components for tensioning the terminating element (112) of the door leaf (110) and a tension force component substantially directed in the movement direction of the door leaf (110) for closing the door leaf (110).

Abstract: The invention relates to a lifting door comprising a movable door leaf formed by slats pivotally connected to each other and building-mounted frames. On the latter lateral guides for the door leaf having a vertical section and a lintel section, as well as a frame seal, which in the closed condition of the lifting door closes a gap between the door leaf and a section of the frames facing the door opening. The vertical sections of the guides are mounted on the frames so as to be displaceable perpendicularly to the plane of the door leaf and fixed in the direction of movement of the door leaf. The invention further relates to a frame and a guide as well as a corresponding method.

Abstract: The present invention relates to a lifting door assembly (1A), in particular a clean room door assembly, comprising a lifting door (2) which has a door leaf (3), an end plate (4), and a door leaf accommodating device (5). The lifting door assembly (1A) also contains a door lintel sealing device (20A) which is provided in the area of a door lintel in such a way that the door lintel sealing device produces a sealing effect between the lifting door (2) and the door lintel. At least one part (10B) of the door lintel sealing device (20A) is pivotably retained by means of a hinge and, when the lifting door (2) is opened, can be pivoted from a door leaf plane by an actuating device in the area of the end plate (4) in such a way that the end plate (4) is arranged substantially completely outside the area of a door opening (O) in the opened state of the lifting door (2).

Abstract: A rolling door having a door leaf and guides arranged on both sides, each of which includes a vertical portion and a spiral portion, wherein the door leaf is received in the spiral portions in the form of non-contacting winding layers when the rolling door is in the opened condition. A drive mechanism for operating the rolling door has a motor, a drive shaft and drive organs. The drive organs are arranged on both sides of the door leaf and the drive shaft establishes a driving connection between the drive organs. In one embodiment, the drive shaft is arranged in the central area of the spiral portions of the guides of both sides and extends from one side of the door to the other. Hereby a rolling door is obtained whose structural height in the area of the door lintel is reduced while maintaining a small installation depth.

Abstract: The invention relates to a lifting door, comprising a movable door leaf made of slats, the slats being connected to one another so as to bend, and comprising structure-mounted frames. Lateral guides for the door leaf having a vertical section and a lintel section, and frame sealing elements of a sealing assembly are arranged thereon, which close a gap between the door leaf and a section of the frames facing the door opening when the lifting door is closed. The lintel sections of the guides, together with the vertical sections of the guides, are displaceably mounted on the frames, wherein the guides can only be displaced in a direction that is diagonal to the door leaf plane, but not in a moving direction of the door leaf. Thus, an improved lifting door having greater operational safety, and at the same time an improved sealing effect between the door leaf and the door opening can be achieved.

Abstract: A high-speed industrial roller door includes a door leaf that is guided in lateral guides and a drive that acts on the door leaf to displace the latter from an open position into a closed position and vice versa. The door leaf is held in the open position so that adjacent areas of the door leaf are not in contact with one another, in a spiral section of the lateral guides located in the vicinity of the door lintel. The roller door also includes a weight compensation device. The drive has two extension arms that are coupled via joints to the lintel end of the door leaf, said arms being situated at a distance from one another across the door width and being synchronously pivoted about a pivoting axis in a central area of the spiral section. The distance between the coupling points of the extension arms on the door leaf and the pivoting axis of the extension arms can be varied.

Abstract: A weight compensation device for a lifting door, includes a spring element and a tensile element, which can be wound onto or unwound from a winding device in such a way that the spring element achieves its greatest pre-tension when the door leaf is in the closed position and is essentially tension-free when the door leaf is in the open position. The tensile element is narrower at the end facing the winding device than at the end facing the spring element and the winding device includes a guide device, which is used to wind the tensile element in such a way that the wound layers lie adjacent to one another without making contact. To achieve this, the guide faces around the perimeter of the guide device have a continuously increasing radius in the winding direction. This enables the provision of a weight compensation device that achieves the torques required for effective weight compensation by means of a simple construction.
