Definitions

  • the present invention relates to a cover member for covering an opening in a cargo space, e.g., openings for receiving removable or foldable tweendeck supports of a cargo ship.
  • Multi-purpose vessels can be used for bulk cargo as well as general cargo or for a combination of both.
  • such vessels can be provided with removable tweendeck pontoons. If the tweendeck pontoons are in place the ship can be used for transporting various kinds of cargoes in various combinations. If the tweendeck pontoons are removed the ship can carry bulk cargo.
  • These tweendeck pontoons are supported by removable or foldable tweendeck consoles. These consoles are provided in openings in the inner wall of the ships cargo space. When the tweendecks are removed, the cargo space can be divided into a number of spaces by bulkheads.
  • the consoles should be moved out of the way.
  • the bulkheads are folded into their respective openings.
  • the consoles can be removed out of their openings.
  • the openings should be closed off to prevent penetration of the carried bulk mass. Hitherto, these openings are presently closed off by metal sheet plates using clips and a rotatable lock. In practice these plates do not seal effectively. The clips tend to break off and the plates are sensitive to corrosion under the influence of moisture and the carried bulk materials.
  • the object of the invention is achieved with a cover member provided with a front side having a flat surface and a back side comprising a sliding member matching the width of the opening.
  • a cover can be easily placed and can form a tight and sealing fit with the opening.
  • the flat front surface makes it possible to position the cover member in such a way that it is flush with the cargo space wall or does at least not protrude from the cargo space wall. This reduced the risk of exposure to impact loads, e.g., when tweendeck or bulkheads are moved to be put in place.
  • the sliding member can have a shape matching with the circumference of the opening, so the sliding member can simply be plugged into the opening to be covered.
  • a cover plug.. is particularly useful for openings for receiving removable tweendeck consoles.
  • the cover member may comprise one flat side and an opposite side provided with a first end with a gripping member and an opposite second end provided with the sliding member, wherein the gripping member has a recess facing away from the sliding member and forming a first contact surface of a width corresponding to the thickness of the wall at the edge of the opening wherein the sliding member comprises a second contact surface facing away from the gripping member, wherein the first and second contact surfaces are configured to form a tight fit between opposite edges of the opening.
  • a cover member can be easily placed by positioning it in such way that the recess of the gripping member grips around a first edge of the opening. Subsequently the plate is tilted to slide the sliding member into the opening to have it clamped against an edge of the opening opposite to the edge cooperating with the gripping member.
  • the cover member is at least partly made of a plastic material, such as polycarbonate or a fibre reinforced plastic or any other suitable type of plastic.
  • a plastic material such as polycarbonate or a fibre reinforced plastic or any other suitable type of plastic.
  • Polycarbonate has the advantage of a very high impact strength.
  • the plastic cover member may comprise a steel plate core.
  • the cover member can wholly or partly be made of steel, aluminium, wood or the like.
  • the cover member can be hollow.
  • it can for example be filled with a foam.
  • the cover member can for instance be produced by rotational moulding, by injection moulding and/or by machining. Other suitable production methods can also be used.
  • the grip and/or the sliding member can be provided with one or more resilient sealing elements, such as rubber sealing strips. Sealing strips of other elastomeric materials, or inflatable strips can also be used.
  • the contact surface of the sliding member can be provided with one or more magnets.
  • the cover member should be flush with the surrounding wall of the cargo space. This can for example be achieved if the edge of the cover member is received in a matching recess bordering at least a part of the opening.
  • the back side of the cover member can for example comprise a flat peripheral edge section, in such a way that the sliding member and the gripping member are at a distance from the outer edge, wherein the opening to be sealed is bordered by a matching recess for receiving the flat edge section.
  • the peripheral edge section can be provided with a rubber strip at the back side of the cover member.
  • the invention does not only relate to the cover member as such but also to a ship provided with one or more of such cover members, either on stock or fitted in corresponding openings.
  • cover members should be used which are flush with the respective wall of the cargo space after being positioned.
  • the invention also pertains to a method of covering an opening in a wall of a cargo space using the covering plates described above.
  • FIG 1A and 1B show a cover member 1 for covering an opening in a wall of a cargo space.
  • the cover member 1 comprises a plate 2 with a flat front surface and a back side 3 with a first end 4 with a gripping member 5.
  • the back side 3 is provided with a sliding member 7.
  • the gripping member 5 and the sliding member 7 have a rectangular shape.
  • the gripping member 5 has a recess 8 facing away from the sliding member 7.
  • the bottom of the recess 8 carries a rubber strip 9.
  • the side 10 of the gripping member 5 opposite the side with the recess 8 is chamfered.
  • the sliding member 7 is triangular in cross section and has a slanting surface 11 facing the gripping member 5, and a flat contact surface 12 which is substantially under right angles with the surface of the back side 3.
  • the flat contact surface 12 can be provided with a rubber strip 13. Alternatively, or additionally, the contact surface 12 can be provided with one or more magnets.
  • a peripheral edge section 14 of the back side 3 is left free by the gripper member 5 and the sliding member 7.
  • the edge section 14 runs along the full outline of the back side 3 and can be provided with a rubber strip 15.
  • the cover member 1 as shown in Figures 1A and 1B with the gripping member 5 and sliding member 7 is a single integral part moulded of a plastic material. Alternatively, it can be assembled of a number of separate parts.
  • cover member of Figure 1 can be provided with a grip.
  • FIG 2A shows the cover member 1 in use, sealing an opening 20 in a wall 21 of a cargo space 22 of a ship.
  • the opening 20 gives access to a foldable support 23, which can be folded about a pivot axis 24 to a position for supporting a tweendeck pontoon 25, as shown in Figure 2B .
  • the opening 20 is bordered by a recess 26 for receiving the edge section 14 of the cover member 1 in such a way that the front side 2 of the cover member 1 is flush with the wall 21 of the ship. This way exposure to impact loads, e.g., by a tweendeck pontoon or bulkhead which is moved to be positioned, is substantially reduced.
  • the rubber strip 13 on the contact surface 12 of the sliding number can be combined with, or replaced by one or more magnets.
  • FIG 3 shows a perspective representation of an alternative cover member 30, shown in side view in Figure 4 .
  • This embodiment is particularly suitable for closing openings for removable tweendeck consoles.
  • the cover member 30 is provided with a front side 31 having a flat surface and a back side 32 comprising a sliding member 33 matching the width and height of the opening to be covered to form a tight, but releasable fit. This way, the cover member 30 can be plugged into the opening to be covered after removal of the tweendeck console.
  • the sliding member 33 comprises a first rectangular section 34 capped by a back section 35 shaped to fill up the major part of the opening to be plugged.
  • the back section 35 is enforced by ribs 36.
  • the front side of the cover member 30 is provided with a cavity 37, which is semi-cylindrical in this embodiment but which may have any other suitable shape.
  • the cavity is bridged by a grip bar 38 allowing a firm and easy grip for a user positioning or removing the cover member 30.
  • the cover member 30 can be hollow.
  • the cover member 30 can for instance be of a rigid plastic material, such as a polyethylene or a polypropylene, e.g., by injection moulding or rotational moulding.
