<p>A positive-action device for bringing about the rotary movement of a hatch (3), as a result of the traversing stroke of a shaft (2) moving axially within a fixed structure (1), particularly in submarine turrets, comprising an actuating component (4) integral with shaft (2) and moving with the latter in a direction parallel to the longitudinal axis of the said shaft, and an articulated kinematic mechanism (9, 6, 7) the upper end of which is hinged to hatch (3), with an interposed flexible safety feature (8), and the lower end of which is rotationally integral with a regulating component (10) rotating around the axis of a fixed pivot (10b), there being associated with such regulating component (10) a mechanism (11) of bistable type for reliably maintaining the settings corresponding to the open and closed positions of the hatch, and end-of-stroke devices (12). <IMAGE></p> |
