Abstract: A bulletproof roller door (1) has a door leaf (2) includes bendably connected door leaf elements (21) and defines a door leaf plane in roller door closed state, the door leaf being moveable between an open position and a closed position via a drive (5). The door leaf elements have cavities (25) with an antiballistic insert (26) insertable therein. The inserts of adjacent door leaf elements overlap in the closed state of the roller door (1). At least one antiballistic defense strip (30, 31) is set at an angle in relation to the insert and covers a gap between the inserts of adjacent door leaf elements in the closed state and is arranged in the cavity of the door leaf element. It is thus achieved that the roller door (1) possess high-speed properties, has a lowest weight possible, and also offers protection against ballistic effects.

Abstract: The present invention relates to a hydraulic door drive for a lifting door (1) that opens, in particular, vertically, comprising at least one hydraulic motor (6), adapted and configured to drive a door curtain (2) or to be at least concomitantly driven by the door curtain (2), at least one hydraulic unit (10) for supplying the hydraulic door drive (5) with pressurized hydraulic fluid (13; 13a), characterized by a pressure accumulator (22), wherein a) potential energy of the door curtain (2), which is released when the latter is closed, can be stored in the form of pressure energy in the pressure accumulator (22), and/or b) the pressure accumulator (22) can be loaded with pressure energy by means of the at least one hydraulic unit (10), wherein c) pressure energy stored in the pressure accumulator (22) can be discharged to the hydraulic motor (6) in order to at least open and/or at least close the door curtain (2).

Abstract: A roller shutter arrangement (1) includes a door leaf (2) including door leaf elements connected together to be angled and guided by guide rollers (23a, 23b) in lateral guides. The lateral guides each include an end portion accommodating the door leaf (2) in a closed position and a storage portion accommodating the door leaf (2) in an open position. The end portion and the storage portion are angled with respect to each other and are connected via a transition portion (42). The transition portion (42) includes guide paths on guide rollers on which predetermined guide rollers roll with a guide length between guide rollers corresponding substantially to a partition defined by a breadth of the door leaf element or to an integer multiple thereof. The so-called polygonal effect is avoided and higher movement speeds of the door leaf (2) are enabled while the service life is simultaneously increased.

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 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: 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: 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.
