Bullet-resistant roller door

A door leaf element for a bullet-resistant roller door, the leaf element comprising:

• door leaf element body defining a cavity in an interior thereof;
• an antiballistic insert having a flat plate configuration, wherein the insert is oriented obliquely in relation to the vertical orientation of the door leaf element and in a closed state of the bullet-resistant roller door the door leaf element overlaps an adjacent door leaf element in a step-shape in an area of a hinge to which the door leaf element body is connected forming a gap between inserts of adjacent door leaf elements;
• and
• two antiballistic defense strips positioned in the cavity at an angle in relation to the insert to cover the gap, with one of the two antiballistic defense strips arranged on one side of the antiballistic insert and another one of the two antiballistic defense strips arranged on another side of the antiballistic insert to form a labyrinth shaped closure between two adjacent door leaf elements.

A bullet-resistant roller door with a door leaf comprising:

• hinge straps with hinge portions each configured to cooperate with one of the hinge portions of one of the adjacent hinge straps to form hinges;
• door leaf elements, each of the door leaf elements being connected to a respective one of the hinge straps to articulatorily connect door leaf elements to one another via the hinges, the door leafs having outer planer surfaces cooperating to define a door leaf plane in a closed state of the roller door, wherein each door leaf is configured to be moved to and fro between an open position and a closed position by means of a drive, wherein the door leaf elements define cavities in an interior thereof;
• an antiballistic insert element inserted in each of the cavities such that each of the antiballistic insert elements of adjacent door leaf elements overlap in the door leaf plane in the closed state of the roller door, so that the door leaf possesses antiballistic properties over an entirety of the door leaf plane in the closed state of the roller door, wherein the antiballistic insert element has a plate-shaped configuration with opposed parallel planer surfaces, wherein the antiballistic insert element is oriented obliquely to the door leaf plane within the cavity of the door leaf element, and wherein in the closed state of the roller door the door leaf elements overlap each other in a step-shape in the area of the hinges and with each antiballistic insert element forming a first gap between the antiballistic insert elements of adjacent door leaf elements at a first insert side of the respective antiballistic insert element and a second gap between antiballistic insert elements of adjacent door leaf elements at a second insert side of the respective antiballistic insert element;
• and
• a first antiballistic defense strip positioned in the cavity at an angle in relation to the antiballistic insert element and extending at one side in relation to the antiballistic insert element to cover the first gap between the inserts of adjacent door leaf elements in the closed state of the roller door;
• a second antiballistic defense strip positioned in the cavity at an angle in relation to the antiballistic insert element and extending at another side in relation to the antiballistic insert element to cover the second gap between the antiballistic insert elements of adjacent door leaf elements in the closed state of the roller door, wherein the antiballistic insert element, the first antiballistic defense strip, extending at the one side and the second antiballistic defense strip, extending at the other side form a labyrinth shaped closure between two adjacent door leaf elements.
