Definitions

  • the invention relates to a closure device for closing an outer skin opening of a surface vessel, with a plurality of substantially vertically arranged sealing lamellae and a drive device by means of which the shutter blades for moving between a closed position and an open position can be acted upon.
  • Such closure devices are generally used in military used over-water vessels to close within the outer skin of the ship arranged spaces and open to the outside if necessary. These rooms serve, for example, as stowage spaces for in-boats, which can be left out of the rooms when the closure device is open, for which purpose, for example, a lifting device can be provided.
  • the closure device has to withstand the same stresses as the outer skin of the ship with respect to water pressure and shock action and is therefore to be interpreted in terms of strength according to the outer skin.
  • JP 2004 026 091 A describes a cover for vertical vertical shutter slats for a helicopter hangar of a naval ship, wherein the cover is designed with respect to a low signature. Furthermore, from DE 102 56 984 B4 a covering device for a recess in an outer shell of a ship is known, wherein the recess is part of a thrower for discharging mortar and / or rocket-like ammunition. This cover device is also designed with regard to a good signature.
  • DE 10 2004 035 640 AI shows a closure for a manhole to a cabin of a sailboat with horizontally arranged shutter blades.
  • this cited prior art does not pay attention to the structural design of the closure or the cover with respect to an impact by Seeschlag or by a shock.
  • the object of the present invention is to improve a closure device in terms of resistance to attack by sea or in a shock.
  • a closure device for closing an outer skin opening of a surface vessel comprising a plurality of substantially vertically arranged shutter blades and a drive device by means of which the shutter blades for moving between a closed position and an open position are acted upon and wherein the shutter blades in an upper and a lower end portion such via sliding elements in each case in an upper and a lower guide rail of the closure device are held to each other, that when moving from the closed position into the opening position position the shutter blades to take the opening position alternately unfolded against each other.
  • An advantageous embodiment of the invention provides that an even number of shutter blades is provided, which are each displaceable in equal parts to opposite sides of the outer skin opening in the open position.
  • the prerequisite is created that the drive device can be of simple construction, since the applied impingement can be applied symmetrically to both parts of the closure lamellae.
  • a staggered storage of the shutter blades is thus achieved to both sides of the outer skin opening in the open position.
  • An advantageous embodiment of the invention provides that mutually facing end faces of the sliding elements of adjacent closure lamellae are in operative connection with one another via a pressure transmission region in such a way that a longitudinal force imposed on the closure lamellae in a direction of displacement for taking the opening position produces a transverse force component on the pressure transmission region.
  • This achieves in an advantageous manner that the introduced kinematics for unfolding the closure elements when moving in the open position only on the shape of the sliding elements, in particular their end faces, is controlled and not additionally movable and / or actuated components must be provided.
  • the pressure transmission region of the end faces of the sliding elements is formed as a rounded contour, for mutual rolling adjacent sliding elements when taking the opening position. This ensures a low-wear relative movement between the sliding elements.
  • the behavior of the shutter blades during folding can be specifically influenced or changed.
  • An advantageous embodiment of the invention provides that the sliding elements of adjacent shutter blades are connected to each other via connecting members. As a result, in particular a force transmission between the shutter blades is ensured when moving from the open position to the closed position. Furthermore, the links assume a guiding function between the shutter blades when moving from the closed position to the open position.
  • An advantageous embodiment of the invention provides that the drive device acts on at least one of the shutter blades for displacement between the closed position and the open position and indirectly acts on the other shutter blades via the at least one shutter blade. This arrangement ensures that the shutter blades which are only indirectly connected to the drive device can unfold into the open position independently of the drive device.
  • the drive device comprises at least one roller chain, via which the at least one shutter blade for moving between the closed position and the open position is acted upon.
  • a roller chain is an easy-to-handle and robust drive.
  • the upper and lower guide rail consists of a plastic sliding surfaces, for guiding the sliding elements in a lateral direction and a vertical direction.
  • plastic sliding surfaces both a low-friction sliding of the shutter blades, as well as a transfer of loads in Seeschlag and in the event of a shock in the ship structure is possible.
  • An advantageous embodiment of the invention provides that the shutter blades are made of a CFK, GFK, steel or aluminum material. As a result, the shutter blades are able to withstand the water pressure.
  • An advantageous embodiment of the invention provides that the guide rails have an inner and an outer lateral guide stop in the direction of displacement of the shutter blades relative to the outer skin opening. As a result, a two-sided guidance of the shutter blades is ensured in the guide rails.
  • An advantageous embodiment of the invention provides that the inner lateral guide stop extends with a shorter course in the direction of the closed position of the shutter blades, as the outer lateral guide stop. This ensures that at least part of the shutter blades in the direction of the ship interior can be released from the guide rails so that it can be brought folded into the open position.
  • the guide rails each have a guide groove extending in a direction of displacement.
  • the guide groove ensures that the shutter blades continue to guide through the guide rails, even though they are in a sliding position in which they are already released from the guide rails towards the ship's interior.
  • the sliding elements have a guide pin, via which the sliding elements are held in the guide grooves for guiding in the direction of displacement. The guide pin ensures that the shutter blades can pivot in a controlled manner with respect to the guide rails as soon as the shutter blades are in a displaced position in which they are already released from the guide rails in the direction of the ship's interior.
  • An advantageous embodiment of the invention provides that the guide pin is arranged in the region of one of the end sides of the sliding elements, wherein adjacent sliding elements are arranged to each other such that those end faces, in the region of the guide pins are arranged, or the corresponding opposite end faces, in the area no guide pins are arranged, in each case opposite each other. This ensures that alternately two opposite end faces of the sliding elements are guided in the guide groove or are not performed.
  • the alternating against each other unfolding of the shutter blades is achieved during the assumption of the opening position, since the shutter blades in the region in which the end faces of the sliding elements are not guided by means of guide pins in the guide groove, can swing away in the direction of the ship's interior and that as soon as the sliding elements of the Guide rails have been released in the direction of the ship's interior.
  • An advantageous embodiment of the invention provides a pressing device, by means of which the two outer shutter blades can be acted upon in a closed position to ship outer against an outer stop.
