  • the launching device is capable of moving the buoyant article out of the receiving chamber and placing the article on the water surface.
  • the luffing jib can be selectively moved to a park and at least one outboard position.
  • the luffing jib can be further transferred optionally in a contracted and at least one exploded state.
  • the luffing jib is completely disposed inside the receiving chamber.
  • the luffing jib is in or outboard position and in the extended state, the luffing jib carries the leash such that: a portion of the leash is external to the vessel and extends from the luffing jib to the subject matter being deployed.
  • the object itself, the leash and the luffing jib are completely within the receiving chamber.
  • the article, the leash jib, and the entire leash or part of the leash are moved out of the receiving chamber with the leash to article section.
  • the invention eliminates the need to place a luffing jib outside of the receiving chamber. Furthermore, the invention eliminates the need to guide a segment of the leash from a launcher boom outside the receiving chamber along an outer skin of the craft while the article is still in the receiving chamber. This leash segment may e.g. be worn down by rubbing. If the receiving chamber is provided with a closure, e.g. a gate, flap or louver system, the invention further obviates the need to provide an opening for the leash in this closure. At least some of these advantages of the invention reduce the signature of the vessel, ie the visibility of the vessel in a radar image. This is particularly advantageous in a military used watercraft.
  • the luffing jib can be brought into a contracted state and into at least one extended state.
  • the luffing jib in the contracted state fits completely into the receiving chamber.
  • the invention enables the luffing jib to be extended in the extended state to hold the leash in such a way that a sufficiently long leash section is formed in front of the exposed object which guides and holds the article.
  • the angle between the line and the surface of the water is allowed to be sufficiently small, for example, in the case of a boat as the buoyant article, not more than thirty degrees. Thanks to the invention, the dimensions of the receiving chamber do not limit the achievable maximum dimension of the exploded luffing jib.
  • the invention makes it possible to actuate, control and / or operate the suspension system completely from at least one position within the watercraft, for example from a control console in the navigation bridge. It is not necessary that a crew member of the vessel or any other person perform any activity on the deck of the craft or even outside the craft to suspend the buoyancy object or to move the launch line.
  • the luffing jib extends along a longitudinal axis, which is preferably at least temporarily arranged approximately parallel to the direction of travel and / or longitudinal axis of the watercraft.
  • the length of the luffing jib that is the extension in the direction of the longitudinal axis, can be changed.
  • the luffing boom is in a contracted condition and fits completely into the receiving chamber.
  • a closure device of the receiving chamber can therefore be completely closed.
  • the luffing jib may be elongated, e.g. in the direction of travel of the watercraft so as to increase the extent of the luffing boom along the longitudinal axis.
  • the luffing jib is transferred from the contracted condition to the or an extended condition.
  • the extent of the leach arm in the or at least one extended state is greater than the maximum extent of the receiving chamber. This achieves in a particularly advantageous manner that the leash section to the exposed buoyant article has a sufficient length and includes a sufficiently small angle to the water surface. This sufficiently acute angle is required to safely guide and hold the settled article in a desired position.
  • the receiving chamber does not necessarily need to be enlarged to achieve this desired effect.
  • the luffing jib is designed to be telescopic. At least two components of the luffing jib extend along the longitudinal axis of the luffing jib, namely at least one inner and one outer component, and are arranged one behind the other.
  • the outer component can be displaced relative to the or an inner component. This allows the length of the luffing jib to change.
  • the luffing jib can be unfolded and folded in the manner of a pair of scissors or a fan.
  • the outer component of the luffing jib can be rotated relative to the inner component, for example by 180 degrees or 90 degrees.
  • the axis of rotation is preferably perpendicular to the longitudinal axis of the unfolded luffing jib.
  • the two components When the luffing jib is in a contracted condition, the two components are folded together and overlap each other. In the extended state, the two components extend along a common longitudinal axis.
  • that portion of the leash extending from the launcher to the exposed buoyant article begins in a boom head.
  • This boom head is mounted on a boom arm of the luffing jib, preferably rotatably mounted.
  • the boom arm preferably extends in a longitudinal axis.
  • at least two pulleys for the leash are mounted on the boom head in such a way that - seen in the running direction of the leash - a distance between these two pulleys occurs. The leash is guided around these two pulleys around.
  • the rotatable mounting of the pulleys and the distance between the pulleys cause a particularly good leadership of the leash and reduce the risk that the leash loses contact with a pulley or the exposed object is not performed correctly. It is also possible that only a pulley on the rotatably mounted boom head leads the leash.
  • the boom head is supported so that the boom head can rotate relative to the boom arm about the longitudinal axis of the boom arm.
  • the boom head is rotatably supported at a free end of the boom. Thanks to this rotatable mounting, the luffing jib with the rotatable jib head can adapt particularly well to lateral movements of the leash. The risk is reduced that the leash slips from a pulley or other guide element and thereby loses contact with the luffing jib or that an abrupt pull on the leash occurs. In addition, the mechanical load on the leash is reduced.
  • the luffing jib is mechanically coupled to a holding device.
  • This holding device can be moved back and forth between a parking position and at least one outboard position. A movement of the holding device from one position to the other moves the leash boom with.
  • the holding device forms a part of the launching device. This embodiment allows a particularly compact design.
  • a winch can roll up the leash and release it later.
  • the winch may include a motor or be operated by hand.
  • this winch is attached to a component of the luffing jib. This component of the luffing jib, and thus the winches, are preferably moved away from the receiving chamber when the luffing jib is transferred to or exploded. This embodiment makes it possible to make do with a relatively short leash. When the luffing jib is in or outboard position, the leash is completely outside the receiving chamber. It does not need to be attached to a fastener of the receiving chamber.
  • this winch is arranged in the interior of the receiving chamber.
  • a closure device for the receiving chamber can additionally protect these winds in the closed position. The winch does not need to be moved when the luffing jib is pulled apart. This reduces the mass that is to be moved during a movement of the luffing jib.

  • the vessel has for each object in each case a solution according to suspension system with a launching device, a leash and a luffing jib.
  • Each luffing jib can be converted to a contracted and at least one extended state, preferably independently of other luffing jibs on board the same craft. Thanks to the invention, it is possible to both objects simultaneously or at least overlapping in time, without the exposure of one buoyant object interfering with the other. This saves time. It is also possible to expose only one object and leave the other in the receiving chamber.

Abstract

La présente invention concerne un système d'évacuation et un procédé d'évacuation destinés à évacuer un objet flottant (2.2) hors d'un compartiment d'accueil (10.2) d'un véhicule nautique (1) sur une surface d'eau (WO), notamment destinés à évacuer un canot d'un garage à canots d'un navire de surface. Le système d'évacuation comprend un dispositif d'évacuation (3.2), une ligne de proue (4) pour l'objet (2.2) ainsi qu'une flèche à ligne de proue (5) servant à guider la ligne de proue (4). Lorsque la flèche à ligne de proue (5) est dans une position de repos et se trouve dans un état raccourci, la flèche à ligne de proue (5) est alors entièrement disposée à l'intérieur du compartiment d'accueil (10.2). Lorsque la flèche à ligne de proue (5) est dans une position hors bord et se trouve dans un état allongé, la flèche à ligne de proue (5) guide alors la ligne de proue (4) de telle sorte qu'il se produit ce qui suit : une portion (13) de la ligne de proue (4) se trouve en-dehors du véhicule nautique (1) et s'étend de la flèche à ligne de proue (5) à l'objet évacué (2.2).
