Bombardment - and anti-break-in safety door

摘要

Bombardment - and inhibiting safety door by refractive index for at least partially closing a wall opening, comprising a door leaf (10) having two opposite main faces (12, 13) and this main faces in a direction of thickness (18) of the door leaf are connected by peripheral narrow sides (14, 17), the door leaf (10) in the direction of thickness (18) at least a bombardment inhibitor plasma it initiates end layer (34, 36, 38) comprises, wherein, in the door leaf (10) at least one recess (40, 41, 42) is formed by one of the narrow sides (14, 17) of the door leaf essentially in a straight line to another one of the narrow sides (14, 17) of the door leaf, and wherein, in the door leaf (10) comprises at least one tensioning element (30) is arranged, which is located in one of the at least one recess (40, 41, 42) of the one narrow side (14, 17) to the other narrow side (14, 17) of the door leaf (10) and which extends in the direction of the connection (32) between the one and the other narrow side (14, 17) of the door leaf (10) is biased to tension.
