Definitions

  • the construction also requires a considerable stowing depth in the moving direction of the cover section as the stay-beams on the underside of each one of the cover sections will be situated against the upper side of the next cover section.
  • a considerably smaller stowing space would be required in case the cover sections could be stowed in such a way that they take a position in which they turn their undersides towards each other as then the stay-beams could be suitably arranged relative each other for engaging the space between the stay-beams on the juxtaposed cover section.
  • the purpose of the present invention is inter alia to overcome the drawbacks described here above.
  • the invention refers more particularly to hatch covers comprising several interconnected hatch covers adapted to be moved on carrying rollers or the like in essentially horizontal position on the coaming around a hatch way to be stowed in vertical position one cover section against the other one at one end of the hatch way. At this end of the hatch way there are arranged inclining rolling paths for pivot rollers on the cover sections.
  • the main feature of the invention is to be seen in the fact that the cover section neighbouring the stowing end of the hatch way (seen in the movement direction) is longer than the next cover section and that the hingedly interconnected cover sections in pairs decrease in length in direction towards the opposite end of the hatch way and further that the pivot rollers on every second cover section are situated in such a way that by pulling by means of a rope or analogous the cover section farmost or next farmost from the stowing end the carrying rollers on the longest cover section next to the stowing end leave the hatch coaming and their pivot rollers run up on the rolling paths, this cover section in a way known per se tilts downwards with its end next to the stowing end and turns the corresponding end of the adjacent cover section upwards, last mentioned cover section turning the adjacent cover section with its adjacent end downwards when the pivot rollers on this section run on the rolling paths and so on.
  • the closing as well as the opening of the hatch cover can be carried out with a single rope. No chains are necessary for the interconnection of the cover sections which in stowed position are in pairs situated with their undersides towards each other. Due to the fact that the cover sections are interconnected by means of hinges the tightening between the borders of two juxtaposed cover sections is facilitated.
  • FIG. 1 shows a hatch cover according to the present invention in closed position
  • FIG. 5 shows the cover in completely opened position.
  • the cover shown in the drawing is intended to be used on main deck on ships and comprises five cover sections 1, 2, 3, 4, and 5. These sections have in the vicinity of one of its transverse longitudinal borders carrying rollers 6, 7, 8, 9, 10, 11, and 12 running on the upper edge of a hatch coaming 14 around the hatch way 13.
  • the cover section situated closest to one end, the stowing end 15, of the hatch way 13 is longest.
  • the two juxtaposed cover sections 2 and 3 have the same width but are narrower than the cover section 1.
  • Next pairs of cover sections 4, 5 have the same width but are narrower than the cover sections 2 and 3.
  • the cover sections are interconnected by means of hinges 16, 17, 18 and 19 in such a way that the cover sections 1, 2 and 3, 4 in folded position are situated with their undersides turned towards each other.
  • the coaming 14 is provided with two roller paths 20 which are arranged beside and outside the running paths for the carrying rollers 6-12. These paths 20 are adapted for cooperation with pivot rollers 21, 22 and 23 extending from both sides of the cover sections 1, 3 and 5, said rollers extending laterally to said roller paths 20. The latter have at their rear ends a stop abutment 24.
  • the pivot rollers 21 on the cover section 1 are situated, seen from the stowing end, beyond the centre of this section, the pivot rollers 22 on the cover section 3 near the centre of this section and the pivot rollers 23 on the cover section 5 are--seen from its centre-situated closer to the adjacent section 4.
  • the pivot rollers 21, 22, 23 are situated on a higher level than the carrying rollers 6-12.
  • the cover can be provided with a further section 27 (indicated with dash and dot lines).
  • the rope 25 is attached at the hinges between the section 27 and the section 5. It is advisable to arrange a spring means between these two sections for facilitating the unfolding of the section 27.
  • the coaming 14 should also be provided with an inclining path 28 for a roller 29 at the free longitudinal border of the section 27.
  • a hatch cover of the kind comprising a number of interconnected cover sections which are movable on carrying roller means in an essentially horizontal position along a coaming around the hatch way so as to be stowed in vertical position one section beside the other one at one end of the hatch way, said coaming at this end having inclining roll paths for cooperation with pivot rollers on said cover sections, the cover section situated next to said stowing end being longer than the next section, said cover sections being interconnected by means of hinges and in pairs decreasing in length towards the end of the hatch way situated opposite said stowing end and said pivot rollers on every second cover section situated in such a way that at a pulling of the section situated farmost or next farmost from said stowing end by a pulling means attached to the section the rollers on said longest cover section situated next to said stowing end leave the hatch coaming and its pivot rollers run on said roll paths, this cover section thereby capable of being tilted downwards by gravity with its end situated closest to said stowing end and thereby
