OPENABLE SUNSCREEN DEVICE WITH ADJUSTABLE SLATS
An openable sunscreen device with adjustable slats comprises a plurality of slat elements (3) moved by at least one distance adjustment member (21) between opened (O) and closed (C) conditions. Each of the slat elements (3) has a respective longitudinal axle (9) whose ends (11) longitudinally slide along respective first site for sliding (15) of side guide element (17). Each slat element (3) has at least one respective inclined arm element (23) provided with a slider element (25). Said device (1) comprises at least one rotation member (27) for the rotation, in the closed condition (C), of each slat element (3), around its own axle (9). Such rotation member (27) comprises a longitudinal track element (31) parallel to said first lateral site for sliding (15) and, for each slat element (3), a corresponding transversal track element (33). The transversal track elements (33) are mutually parallel and inclined with respect to the longitudinal track elements (31) and placed at mutual distances equal to the maximum distance value in the closed condition (C) between said axes (9). Each transversal track element (33) intersects the longitudinal track element (31) at a respective switch element (35) provided with a corresponding swivelling track element (37) rotatable between a rotating condition in which it (37) is aligned with the respective transversal track element (33) and a sliding condition in which it (37) is aligned with the longitudinal track element (31). The device further comprises translation actuator members (41) of the rotation member (27) for moving it parallel to the longitudinal track element (31) and swivel actuator members (43) to rotate the swivelling track elements (37) in synchrony between the rotating and sliding conditions.
