Definitions

• Venetian blinds with strips that can be oriented and wrapped are useful only to regulate light and air without having any defensive force.
• the conceived device puts into effect for the first time a "Nenetian blind” that, together with the merit of allowing the best visibility and airing, is an effective defence.
• the Venetian blind that can be applied anywhere, works with capstan control mechanisms with a flying rod and an electric engine already on the market that are inserted inside a box (Fig. 2 ⁇ . 1) applied at the ceiling and having on the outer face a steel veil (Fig.3 ⁇ . 2) covering the joint with the last slat while in the inner side it has a cap to access to the commands.
• suitable containing guides are fixed with screws (12) special guides which are made up by two parts, a fixed one and a mobile one (Fig. 4, 5) linked by a hinge (5) that on one side has a latch bolt with hooks (Fig. 7 ⁇ . 13) and on the other side it has plates with receiving holes for the hooks of the bolt.
• the guide opens when the bolt (13) is lifted and pushed towards outside by a lever inserted in its top (14) run by the commands placedut in the box (1 ), it closes when the command works in the opposite way.
• the fixed part of the guide (4) has two opposing fins (10) which mark the space (34) where the heads of the pins (30) are kept coupling the single slats (3).
• the mobile part of the guide (Fig. 5 N. 6) is milled to create notches (Fig. 3, 6 N. 7) used to regulate the inclination of the slats.
• the sections produced in the guide by the creation of the notches have holes that are closed with nylon plugs (32).
• the guides have two grooves (11) where nylon buffers for sealing the slats are inserted.
• the Venetian blind can assume three positions:
• the slats of the Venetian blind are in mould metal and their ends are curved (15) for a perfect coupling and to prevent the penetration of the rain, in the lateral sides they have strengthening bends (16) to contain the supporting profiles of the inner sheating (Fig. 8, 9 N. 17, 18) that contains: the two heads of a curved sheet made of tempered steel (Fig 8, 9 N. 20) whose coins also support the walls of the slat, the cut-proof steel round (Fig. 8, 9 N. 19) that is inserted in the profile (17) and is used also as axle-tree for the hinge of the central fillet (Fig. 8, 10 N. 25), the steel tube (Fig. 8, 9 N.
• slats are linked by tempered stainless steel fillets (Fig. 8 N. 25, 26, 27) that synchronize their movements.
• a lateral fillet (Fig. 8 N. 26) links the basis of the slats to which some pins are fixed (30); these pins go trough its eyelet and the special spacer (Fig. 9 N. 26, 29).
• the other lateral fillet (27) is fixed with a screw to the plug (22) using a spacer (Fig. 9 N. 27, 28).
• the cylinders (31) are inserted and then blocked with the punching of the tube above their notches or with electric welding.
• the tube (21) is inserted in the profile (18) while in the other supporting profile (17) the steel round is inserted (19).
• the heads of the curved sheet (20) are inserted.
• the pre-arranged inner sheating is inserted inside the slat (3) whose ends are closed with metal plugs (22) fixed with a screw (Fig. 9 N. 35).
• the slats are lined up on a table and the pins are inserted (30); after having put the overlapped eyelets of the fillets (26), the spacer (29), the plug (22), are screwed down in the cut screw groove of the cylinder (31) strongly linking all the parts (Fig. 9).
• the overlapping eyelets of the other fillet (Fig. 8, 9, 11 N. 27) are inserted in the spacer (28) and fixed with a screw to the plug (22).
• the eyelets of the lifting ropes are screwed down to the plugs of the first inferior slat (Fig. 9, 11 N. 23). If the central fillets (25) are applied instead of the lateral ones (27), in the slats already containing the inner sheating, but without the steel round (19), the notches (33) are made to receive the two parts of the fillets (25) that are then passed trough and joined by the steel round (19) inserted in the profile (17).
• the milling area (33) of the slats (3) is pointed out in figures N. 10 and 13 and has the same width of the fillet that it receives.
• the guides (4) and the box (1) are fixed to the lateral walls and to the ceiling with strong screws.
• a small plinth is fixed (Fig.8 N. 24); it improves the linking of the first slat with the base.
