| 摘要 |
The present invention relates to an innovative simplified system (1) for slideable and articulated connection of metal slats (2) for providing anti- burglary roller-shutter curtains for residential, commercial, and industrial roller shutters with variable gap (Lv) or fixed gap (Lf) for passage of light between slats. In the first case - variable gap (Lv) - the mutual connection of each pair of slats (2) is obtained via connecting rods (3), hinging means (10, 11, 12), and slots (8) made strictly adjacent to the ends of the slats (2), namely, in the part of the slat (2) that can slide along the rails of the lateral guides. These means (3, 10, 11, 12) and the corresponding slots (8) are designed both to enable articulation of the slats (2) during rolling of the roller-shutter curtain and to space the slats (2) themselves apart from one another. In the second case - fixed gap (Lf) - the mutual connection of each pair of slats (2) is obtained via brackets (5) which constrain said connecting rods (3) with pins (7). |
