ABSTRACT:
On an attack-endangered side of members (1, 6) of a fixed frame and a sash frame mounted swingably therein, respective bombardment-inhibiting profiles (11, 12) with overlapping edge margins (11', 12') are provided. In the overlap region these safety profiles (11, 12) define a gap (13). Since the edge surfaces of the bombardment-inhibiting profiles (11, 12) which define the gap (13) are formed with respective ridges (4, 17) and grooves (15, 16) intermeshed with one another, the gap course is sinusoidal. This offers a high degree of security against shoot-through and break-in in the gap region of the door or of the window.
