<p>A control and movement device (1) for mosquito screens, curtains and the like, which are movable and of the roller type, which comprises a frame for supporting a sheet (3) that can be installed at an opening in an element of the type of a wall and the like, the frame comprising a fixed box (4), which is coupled to an edge of the sheet (3) and is associated stably with a corresponding margin of the opening, and a movable box (5) which is fixed on the side opposite to the sheet (3) and is able to perform a translational motion along respective lower guiding means (6) and upper guiding means (7) on command, along a direction which is substantially perpendicular to the fixed box (4), for the transition from a first configuration, in which the sheet (3) is substantially gathered at the fixed box (4), to a second configuration, in which the sheet (3) is extended to cover the opening, and vice versa. The lower guiding means (6) comprise a link track which is constituted by a plurality of mutually articulated segments and has a first end (8) coupled to the base of the fixed box (4) and a second end (9) which can slide into an inner seat of the lower headpiece (5a) of the movable box (5). The upper guiding means (7) comprise a flexible tape (16) having a first end (10) which is coupled to the top of the fixed box (4) and a second end (11) which can slide into an inner seat of the lower headpiece (5a) of the movable box (5) and is rigidly coupled to the slidable second end (9) of the link track (6) downstream of adapted transmission means (12) which are inside the movable box (5).</p> |
