Abstract

Improvements introduced into actuation devices for hatch covers comprising at least three hinged interconnected panels, of which the first is rotatably connected by hinges to a transverse side of the coam and is actuated by means of at least one straight piston actuated by assembled fluid under pressure I entered said panel and the adjacent side of the coam, characterized in that the fastening of the piston or each of them to the panel includes a guide member movable in an elongated indentation in the panel and that the adjacent piston to the guide member it carries a first pulley for a cable connecting the first panel to the third panel; in that a second pulley is mounted on the first panel adjacent to the hinged connection between the first panel and the second panel; and because one end of the cable is attached to the first panel at a point between the two pulleys and is led over the first pulley, then back to the second pulley and finally to the third panel, to which its other end is attached at one point next to the edge of the same away from the joints between the third and the second panel; the piston and cable being designed in such a way that the piston, when the lid is closed, is retracted and extends to the end of the slit away from the rotary joint in the coam and by elongation it can fold the first two panels together to bringing them into a vertical position, and after this will contractively guide their guide member down the length of the slit, thereby raising, during the lengthening of the cable between the two pulleys, the third to a vertical position.
