The anti-mosquito screen system with articulated guides (2 & 3) consists of a strap (4) placed vertically and revolved around two pulleys inside the restraint (1) or sliding box (14) and along it. The strap forms on each of its side two implied parallelogram parallel sections, the internal (19) and the external (20). The articulated guides enter and get out of those sections. To one pulley (5 or 6) is connected a special stabilization accessory of the strap's height (8) in stable position, vertically to the internal wall of the box fixed by two screws (15), inside two grooves/"teeths" (16). The accessory is the point on which one of the two articulated guides terminates its sliding. From the point that the accessory lies and above, the user is able to cut the box at the exact height of the frame. The two articulated guides lied inside the box are in vertical position, parallel to each other, with the strap's sides and the walls of the box. |
