Abstract

A collapsible lid arrangement for hatches installed on board ships or similar openings of the type in which the lid sections are hingedly interconnected, with a first section hinged at one point that is solidly connected to the deck of the ship so that this first section, together with the adjacent second section, can be pivoted to a vertical position with the lower faces of the two sections facing each other, and a third section that hingesly connects to the second section can be pivoted to a vertical position with its upper face facing the upper face of the second section, all movements being carried out by means of hydraulic means mounted between the deck hatch coam, on the one hand, and the first and third sections, respectively, on the other hand, in which a lever is pivotable around a fixed point by hydraulic means and close to its end l ibre is provided with a claw adapted to receive a pin in the third cover section when the first and second sections are approaching their vertical position.
