<p>This invention refers to window screening and protection devices, particularly, to blinds' systems located inside the double-glazed knot. The objective of this invention is a complete provision of the acoustic isolation and simplification of the construction. The proposed driving device for the blinds' systems (Fig. 1) contains cords that move with a help of rollers, which are located inside the double-glazed frame. The innovation of the invention: cords are tightened on a longitudinal axis, connected with the help of mutual interaction with the roller, where a gear of the gear block is mounted, which, by turning, is connected with a star, geared with flexible elements, and mounted with the help of an option moving back and forth. In addition, the invention works on a magnetic slide, which contains magnetic elements, one of which is tightened on a flexible element, while the other is mounted on the frame's external surface with the help of a longitudinal moving option. In the frame's internal hole, over the length of the whole perimeter, are acoustic isolation blocks. Flexible elements are suspended.<IMAGE></p> |
