Definitions

• the invention relates to a device for a ship for boarding and launching swimming or diving objects, in particular boats.
• boats of any kind are to be brought on board as swimming or diving objects, e.g. Dinghies or even the latest passenger submarines used in the type of passenger ship.
• pilot displacement boats, marine research submarines, other marine research equipment, swimming lighters, beard sight or, for fishing, trawls are also particularly suitable.
• the invention has for its object to provide a device of the type mentioned, in which compared to known devices the boarding and dispensing of swimming or diving objects can be done more safely and smoothly.
• the object has been achieved according to the invention by a device which is distinguished by a chamber for receiving the object which can be extended and retracted from the hull of the ship and is at least partially submersible in the water and which is at least partially designed to be opened in the manner of a gripper.
• the extendable chamber can then be extended, for example, from a loading hatch or through a tailgate of a ship and can be completely or partially immersed in water.
• the chamber is then opened in the water by opening the gripper.
• the object to be picked up can either move itself into the gripper or the chamber can be extended so precisely that the gripper legs that already open when the chamber is extended are located on both sides of the object to be picked up.
• the gripper legs can preferably be opened at the largest possible angle, so that the gripper legs encompass a considerably larger water area than that which is taken up by the object to be picked up becomes.
• To pick up the object it is only necessary to bring the ship so close to the object that it is in the exit area of the chamber located. Even automatically moving the object between the gripper legs is not too difficult when the gripper legs are open, even when the sea is rough or the sea is rough, since this does not require very great accuracy.
• Ships have also already been proposed which preferably have a kind of harbor basin in the stern area, which is partly below the water surface and can be opened to the sea through a flap or the like, so that boats or the like can enter this harbor.
• a run-in is also difficult in rough seas because this requires maneuvering accuracy that cannot always be achieved in rough seas.
• Such a ship can be retrofitted in a particularly simple manner with the device according to the invention, since practically only one extendable chamber has to be used in this harbor basin.
• the mer at 'the extended position of the Chamber unfolded gripper arms form in front of the pool then a kind of funnel that facilitates Einmanövr Schl in the harbor of the ship.
• the object to be picked up is initially between the gripper legs. A further maneuvering of the object is not necessary since the object is brought into the correct position in the chamber by simply closing the gripper legs.
• the device according to the invention does not necessarily have to be installed in the hull of a ship, so that it is in the hull the ship retracts, but it is also advantageously possible to install the device according to the invention in catamarans or half-catareas, so that the retractable and extendable chamber is not in the hull but between two hulls.
• the axis of the gripper does not hinder the picking up of an object. It can be an imaginary axis, which is fixed, for example, only by a joint.
• the gripper legs of the gripper are at least as long as the object to be picked up or brought out.
• the chamber is advantageously longitudinally divided at least in its outboard-facing section in order to form the gripper, and the two half-parts as gripper legs are one of yours axis oriented to the extension direction is pivotally connected and foldable together.
• the chamber is designed as a gripper as far as possible, whereby it is divided symmetrically.
• the axis preferably lies in the vertical plane of symmetry of the ship, i.e. the gripper is preferably not designed so that a gripper leg stands under water and a gripper leg stands above water. Training that would be conceivable.
• a next development of the invention provides that the half parts, i.e. the gripper legs are bowl-shaped, so that surfaces of the half parts oriented perpendicular to the axis abut against one another during the gripping movement.
• the bowl-shaped design of the gripper legs advantageously encompasses the object to be picked up or brought out from five sides, preferably even on all sides, and not only in the manner of pliers, so that it is completely safe in the chamber when the gripper is closed.
• a next development of the invention provides that the half parts have sections which point from the axis towards the inside of the ship and that the surfaces of these sections oriented perpendicular to the axis face towards the inside of the ship -Narrow direction in such a way that when the gripper is closed they gap apart like an open beak and when the gripper is open they abut each other as if with a miter. Due to the fact that the half-parts are elongated as far as possible beyond the axis, particularly long guide and contact surfaces are advantageously made available, due to the narrowing of the gripping legs! in the inward direction of the ship, the gripper can be opened as far as possible despite this long design.
• the gripper legs should preferably be opened approximately to an angle of 90 ". _. ⁇ _.
• the gripper legs can be pivoted with one another when the gripper is open, preferably about its opening axis, when the gripper is extended outboard.
• the opening formed by the gripper can advantageously be oriented in different directions, as a result of which the weather conditions can be taken into account.
• the gripper can be positioned at a certain angle to the flow, the wind direction or the like. As a result, the picking up and discharging of objects can be carried out much more easily and reliably with the device according to the invention, even when the sea is unfavorable per se.
• the chamber is preferably mounted displaceably in a corresponding guide, wherein the chamber or parts carrying the chamber can be designed as a slide.
• a reduction in the frictional resistance during displacement can take place, for example, by means of guide rollers.
• drive means preferably hydraulic means
• Drive means are preferably also available for seduction to open and close the gripper.
• the drive means for opening and closing the gripper can be dispensed with under certain circumstances, since the gripper is also closed automatically by moving the chamber into the guide, by guiding the gripper legs on the guides and moving towards one another until the closed state be pressed.
• opening the gripper can sometimes be achieved by the water resistance when the chamber is extended, which can be reinforced by a backward movement of the ship.
• This pressing of the gripper legs by the water can also be achieved, for example, by arranging the outwardly facing end surfaces of the gripper at an angle to one another. the, so to speak, according to the reverse principle of goal gates.
• the device according to the invention should preferably be installed in ships which have an azimuthal drive, which improves the maneuverability of the ship when handling the device according to the invention becomes.
• edges of the side wall of the ship which run parallel to the opening axis of the gripper and are adjacent to the chamber are guides for the opened, extended gripper legs when retracting, so that the gripper legs already move close automatically when entering the chamber due to these guides.
• Another advantageous embodiment of the device according to the invention is characterized in that the outwardly facing parts of the chamber wall are parts of the side wall and form doors closing the side wall when the chamber is retracted.
• the chamber preferably has an extension limit preventing the chamber from moving out completely, so that the chamber does not reach the entire outboard area, but remains in the area of the ship with one, if only a short, section.
• a next development of the invention provides that at least some extendable sections of the wall of the chamber have water passages, so that there is no excessive water pressure on the gripper legs, which might have to be caught by hydraulic cylinders or the like when the gripper is open .
• the chamber can preferably even be cage-like.
• the chamber is box-shaped at right angles.
• the chamber can have inserts which are adapted to the shapes of the object to be accommodated and which are installed or removable and by which the object to be accommodated is gripped more securely and supported in the chamber.
• An alternative embodiment of the device according to the invention provides that the direction of extension of the chamber is oriented horizontally, the direction of extension preferably being oriented parallel to the longitudinal axis of the ship.
• the chamber can preferably be extended through the stern of the ship. In this way, in particular boats or other floating objects can be picked up, and in particular if the chamber can be extended through the stern of the ship, no undesired heeling of the ship occurs due to the picking up or spreading out of the object.
• the chamber can at least partially be arranged under the water surface from the outset, so that it only needs to be extended and then a swimming or diving object can swim into the open chamber. If the chamber is only partially submerged in water, it can be open and basin-shaped at the top.
• the wall opposite the gripper, or possibly another wall is to be opened, since the object just picked up can then be pushed out of the chamber, so that the chamber is quickly cleared for the next object.
• the chamber is arranged to be adjustable in height.
• the chamber can its rest position above the Wasserober ⁇ disposed surface to be even on deck of the ship, and it is then either first extended horizontally and then up lowered into the water, but they may for example also through a manhole in the vessel, e.g. can be lowered into the water through an opening of the ship's floor hatch, after which it can possibly still be extended horizontally under water In any case, it is conceivable to combine horizontal and vertical movement possibilities of the chamber with one another.
• a further development of the invention provides that the chamber can be lowered to below the keel of the ship, this lowering can take place far below the keel, for example the chamber can be lowered on extendable guide rails or the like far below the ship.
• the direction of extension of the chamber is oriented perpendicularly from the outset.
• the chamber can preferably be arranged amidships, preferably in the area of the ship's center of gravity, and can be lowered to below the keel of the ship, for example through a shaft or the like.
• diving objects such as submarines
• An arrangement of the chamber in the center of gravity of the ship means that there is particularly little impairment of the movement of the ship due to the taking up or bringing out of the object and vice versa of the taking up and bringing out of the object due to the ship's movement.
