Abstract

1391085 Hatch covers DEUTSCHE MACGREGOR GmbH 4 Aug 1972 [4 Aug 1971] 36491/72 Heading B7S A hatch cover comprises a pair of folding covers 1, 2 articulated at 4 to one end 6 of the hatch and at least one further pair of folding covers 8, 10 is articulated to the first pair. A drive mechanism 20 interconnects adjacent covers 2, 8 of adjacent pairs and a piston 18 mounted on cover 2 operates the drive mechanism to effect swivelling between each pair of folding covers and the adjacent covers 2, 8 of adjacent pairs. The drive mechanism comprises four links, the first of which is a crank 34 pivotally mounted at 14 on cover 2 and being pivotable by the piston. Second link 12 is pivotally connected to the crank pivot and at 16 to cover 8 of the further pair of folding covers to allow adjacent covers 2, 8 to be swivelled through 180 degrees. The third link 40 is pivotally connected to the crank at a position 38 spaced from the pivot 14 and is pivoted to cover 8 at a position 42 spaced from pivot 16. The fourth link of the drive mechanism is plate 48 fixed to cover 8 and to which the second and third links are pivotally connected at 16 and 42. The distance l, between a line of action of the piston and pivot 14 is shorter than the distance l 2 from pivot 14 to a line joining the pivotal connection of third link 40 when the covers are in their fully-extended or closed positions. The hatch cover also includes elements 28, 30 by which covers 8, 10 are held in the extended position during the folding-up of covers 1, 2.
