Security grille for preventing cutting through anti theft device, comprises casing with bar held inside it with spring

摘要

The grille comprises an elongated casing (1) containing at least one elongated bar (2) extended under spring tension inside the casing via at least one spring (3) that has one end applying a spring pressure to a casing end section (4). The bar is divided in its length direction into two or more sections (2a-2c) lying side by side. The shape and cross-section of the bar are adapted to the shape of the casing so that a cut-off end of the bar can not be pushed part the other end. The bar exerts a pinching force on anybody trying to cut through it.
