BULLET-RESISTANT ROLLER DOOR
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.
