Window or door fastening pivoting on frame, with locking mechanism

摘要

The locking mechanism consists of at least two holders (7,8,18,19) made of mechanically stable material and enclosing a hollow cavity. A mechanically stable bar-shaped element (9) consists of two telescopically interfitting movable parts inserted into or through the holders. When mounted, the two axial ends of the bar-shaped element fit into the holders restricting the axial movement of the bar-shaped element. The holders are firmly mounted on two opposite facing sides of the window or door. The first holders are anchored in the building masonry (6) or on parts of the building structure, on the frame (4).
