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: 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: 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: 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.
