DK 155756B

The present invention relates to a projectile-inhibiting aluminum window for buildings for protection against projectile fire from all types of small arms, including machine guns, and with a projectile-inhibiting layer of an aluminum alloy.

With aluminum window frames of similar type, attempts have been made to achieve a shot-retardant design by filling the cavity in the aluminum profiles with shot-retardant material. However, these methods did not produce the desired result, as the aluminum window bracket chamber could not be filled with the bulletproof material, as this would impede the necessary movement of the bracket parts so that the window could no longer be opened.

Furthermore, attempts have been made to make window wing and window blind frames of wood projectile by placing metal on the wing and blind frames, but these attempts have not led to a favorable result either.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a suitable window frame which, in connection with safety glass known per se, protects the people in the building from the shooting of 25 persons armed with handguns including machine guns and which can also be manufactured in known manner on machines. without special equipment.

This task is solved according to the invention by an aluminum-3Q window, which is characterized by the characterizing part of claim 1.

Also, in order to simply prevent a shot penetration in the 45 ° opening to the window plane, a design according to the characterizing part of claims 4 and 5 has been proposed.
