Window or door with protection against explosive effects

A closure for an opening in a building having a visible side, comprising:

• a transparent covering for the opening;
• at least two frame elements enclosing the covering in a substantially circular fashion, wherein the frame elements are connected in a force transmitting manner;
• at least two pairs of rectangular brackets fastened to the frame elements on at least two opposite sides of the covering, wherein at least one tensile leg of the brackets is spaced from a reveal of the opening, and wherein at least one supporting leg of the brackets extends at a distance from the visible side of the building adjacent to the opening;
• and
• at least one dampening element located between the supporting leg and the visible side of the building, wherein at least one of the brackets is attached at the frame by at least one fastening means along the tensile leg of at least one of the brackets, and wherein each bracket is secured to the building by a fastener and a dowel arrangement wherein the fastener passes through an oblong hole in the tensile leg of each bracket and penetrate the building so that the frame elements are indirectly connected to the building.

A closure for a building designed so as to be inhibitive to an explosive effect, with which an opening in a building can be closed off, comprising:

• a filling;
• and
• frame elements substantially enclosing the filling in a circular fashion, the frame elements connected by fastening elements to the building adjacent to the opening, wherein rectangular brackets are fastened to the frame elements on at least opposite sides of the closure, wherein a tensile leg of the rectangular brackets extends close to the reveal of the opening, wherein a supporting leg of the rectangular brackets, the supporting leg extending in a substantially perpendicular manner relative to the tensile leg, extends at a distance from a visible side of the building adjacent to the opening,
• wherein the fastening elements penetrate the building in a direction generally parallel to the plane of the opening, wherein a damping element is arranged between the supporting leg and an associated abutment surface of the visible side of the building, wherein anchor-like fastening elements are arranged in a region of the tensile leg and allow a displacement of the closure in a direction perpendicular to a plane defined by the filling, and wherein the fastening elements penetrate through oblong holes in the tensile leg, the oblong holes extending parallel to a direction of the displacement of the closure.
