System of sliding metal sheets for prevention of violation of doors and windows, with sliding single (29), divided (30) or folding (31) metal sheets that do not remain permanently in front of door (18, 19) or the window (20), but are found either on one side of the masonry (11 ), or even on the two sides of it, depending on the space that exists in the masonry (10), and the length of the gap (16, 17) that will be secured. When the into account gaps of doors (18, 19) or windows (20) are secured, part of the sliding metal sheets (29, 30) that secures them, remains inside the masonry (10) and from its both sides, so that they do not open but only slide. They are manufactured from metal balustrades (36), or panel (37) or profile (38) or even combination of these (39, 40). The metal balustrades (36) if they are not obvious can remain as the main material of the metal sheets (29, 30, 31) and are placed inside the panel (39) or profiles (40). They function also move with rollers (78) on the system driver (53), or in part of the driver that use other sliding systems (56), or with sliding driver (52) that is placed above (lintel). The sliding metal sheets (29, 30) secure mainly from the internal side of the gap with dowels (63, 64), where they function as lock in the attempt the metal sheets (29, 30) to be drawn, they are found in the internal part of the masonry (10) in a small distance from the its finishing, towards the gap of the door (18, 19) or the window (20) and at a height that can be selected. The dowels (63, 64) pass, either from the finishing of the sliding metal sheets (29, 30) or from holes (51) in concrete points of the sliding metal sheets (29, 30), while they can also be secured with locks (72), turned or pressed buttons (79). In the binding of the divided (30) and folding metal sheets, safety dowels between sheets (85) are placed, which move in their sockets (86). It is possible however for the sheets (29, 30) to secure as well, from the exterior side of the vacancy from the wireless frequency appliance (81) that activates a mechanism of movement (80) or by a dowel lever (87). The system can be placed completed in a frame and before the completion of the work of the masonry. The panels (37) and the profiles (38), are manufactured, invested and decorate from aluminium, timber, plastic, other metal, mixed, or glass in various designs, forms and colours. |
