摘要： 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.

摘要： 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.
