Description

The invention relates to a device for a watercraft for recording and Exposing swimming or diving objects, with an at least partially submersible transport device for taking up and transporting the Object from the water onto the watercraft and vice versa.

Such a device is known and is found in particular in private yachts in use and is mainly used for picking up and launching Tender boats or seaplanes used. But it is also conceivable that a such device on commercially used ships such as cruise ships, but is also used on all other types of ships Pick up objects from water or expose them to water, whereby as objects, for example, diving bells can also be considered.

A known device of the type mentioned is with a rail-shaped Boom, which is permanently installed at the stern of a private yacht and in protrudes into the water at an angle to the horizontal. On the rail-shaped A carriage is arranged to move along the boom, which is provided with a holding device is provided for receiving a seaplane.

No. 5,664,516 A discloses a similar device, which is a rail-shaped device Ramp has that on the rear deck and the mirror of the The stern of a motor boat is arranged to extend beyond the stern to the rear extends and ends just above the construction waterline. The rail-shaped Ramp is used for direct gliding of a dinghy or jet ski, by pulling it onto the motorboat along the rail-shaped ramp. however, in this known construction, a sled and the like. not provided, which creates greater friction, which is disadvantageous for handling is.

Another device is described in DE 195 00 182 A1, which differs from distinguishes the aforementioned device in that the one end of the Boom can be freely pivoted on the watercraft around a horizontally aligned axis is so articulated that the boom is at an acute angle to Water surface extends and the free end of the boom in the water swims. Accordingly, in this known device the boom with the Watercraft not fixed, but pivotally connected about the axis mentioned. In rough seas, the end hinged to this axis follows the movements of the watercraft, but not the free end on the Water surface. Due to the free pivotability of the boom accordingly the movements of the watercraft at sea are balanced.

EP 0 362 722 A1 discloses a device for picking up and releasing of swimming or diving objects, one from the hull of the ship extendable and retractable, at least partially submersible in the water Includes the objects, at least partially in the manner of a Gripper is designed to be foldable.

DE 36 35 238 A1 and DE 37 32 507 A1 each describe a ship, which is provided with a closable rear opening, the Lying behind the stern opening and for receiving dinghies, lifeboats etc.. provided space is completed by a floor that can be moved downwards is.

The construction of the aforementioned known devices is hydrodynamic unfavorable and / or technically complex and therefore expensive in terms of Manufacturing, operation and maintenance.

It is an object of the present invention, a device of the aforementioned Kind with a technically simple and at the same time hydrodynamically favorable Propose construction.

This object is achieved in that the above-mentioned device Type the transport device between a working state by doing it at least partially immersed in water, and a hibernation by is arranged outside the water, is bringable.

The solution according to the invention has the advantage that when not in use, that is Hibernation, the hydrodynamics of the watercraft remains completely unaffected, because according to the invention in this state the transport device at a point on Watercraft is placed outside of the water and therefore does not have the flow resistance of the watercraft forming an obstacle. Doing so the invention takes advantage of the fact that experience has shown when operating the Watercraft the device for receiving and launching swimming or Diving items unused for the vast majority of the time remains and is only used for relatively short periods of time.

Accordingly, the invention has an extremely advantageous effect on the speed and the fuel consumption of the watercraft.

In addition, the solution according to the invention offers a technically proportionate simple construction, since with the help of the transport device according to the invention the swimming or diving objects on the deck or in a chamber or Garage above the waterline can be spent on training of complex underwater spaces that have to be partitioned off and locked can be dispensed with.

A technically particularly advantageous construction can be telescoped Achieve training of the transport device. This leads to a particularly space-saving and otherwise technically not very complex solution.

The transport device expediently has a frame and a frame along the Frame movable support element for receiving the floating or diving body on. The frame should preferably be designed to be telescopic.

The frame expediently has at least one rail and at least one in each case a slide that can be moved along the rail for holding the support element on. Usually there are two parallel spaced rails provided that extend at an angle to the horizontal.

The rail preferably consists of a plurality of telescopic ones Sections, these sections expediently movable into one another are arranged. Thus, the rail can be put in the idle state shorten by pulling the telescopic sections out of the water and shifted into each other above the water line. In the working state on the other hand, the rail with its telescopic sections is at its full length undressed and protrudes with its free end into the water to over the sled to take the swimming or diving object out of the water or into it To expose water.

In another currently particularly preferred embodiment, the support element to hold the swimming or diving objects on the rack and in In the case of the arrangement of a rail and a slide movable thereon arranged on the slide to be uncoupled.

In a particularly preferred development of the aforementioned embodiment the support element in the uncoupled state to a portion of the Hull of the watercraft can be held, which makes it particularly easy Storage possibility for the support element when not in use.

The supporting element expediently forms one, preferably essentially horizontally oriented, platform, which is particularly suitable for accommodating tender boats or seaplanes is beneficial.

The aforementioned embodiment can, for example, on a watercraft be realized, which is a flap for closing an opening in the fuselage has, wherein the support member in the uncoupled state on the Flap can be held. This will be a very nifty storage option for created the support element.

A further development of the aforementioned embodiment of a watercraft is characterized in that the flap and the device are designed in this way and are arranged adjacent to each other that in the open position Flap the support element can be uncoupled from the frame and can be held on the flap and / or is removable from the flap and can be coupled to the frame. In case of Arrangement of at least one rail should be used to connect and disconnect the support element the slide should be positioned approximately at the level of the flap; is the Flap pivotable about a substantially horizontal axis of rotation, should for the coupling and uncoupling of the support element of the carriage approximately at the level of Axis of rotation of the flap can be positioned. Furthermore, the flap can be a recess have for receiving the support element, making one particularly simple and, on the other hand, optically unobtrusive storage option for the flap is created. Finally, the flap and the support element for decoupling the support element from the frame and the inclusion of the Supporting element on the flap in a substantially parallel and sealed adjacent arrangement and for the transfer and coupling of the support element be brought to the frame in substantially the same arrangement.

The embodiment described above is particularly suitable for an arrangement a so-called transom flap between two rails, the transom flap serves to lock a room behind and the two Rail parts of the device according to the invention in the previously described Are provided so that the device for receiving in this embodiment and exposing swimming or diving objects to them Deck transported above the space that can be worn by the transom flap.

A preferred exemplary embodiment of the invention is explained in more detail below with reference to the accompanying drawings. Show it:

Figure 1 shows the stern of a ship in the fully closed state.

Figures 2 to 9, the opening of the tail and the provision of a transport device for receiving a seaplane.

As can be seen in particular in FIG. 1, the stern section 2 of a ship 1 shown. The ship 1 can preferably be a private yacht.

The stern section 2 has in the illustrated embodiment of the ship 1 accessible upper outer deck 4, at the rear end of which there is a first Tail section 6 connects, the kind of a negative mirror of a modern Yacht is tilted backwards and downwards. This first rear section 6 has a rectangular opening in the middle, which is opened by a transom flap 8 is closed. The transom flap 8, which in Figure 1 in the closed state is shown and extends over the entire height of the first rear section 6, is about a horizontal and perpendicular to the longitudinal axis of the ship 1 Pivot axis 9 pivotable, which is adjacent to the rear end of the upper outer deck 4 is arranged, as shown in Figure 1.

As can also be seen in FIG. 1, lies on the outer surface (visible in FIG. 1) the transom flap 8 on a platform 10, which is designed as a plate and in shown embodiment has a T-shape. This is the transom flap 8 on its outer surface with a corresponding (not shown in the figures designated) recess for receiving the at least partially offset Platform 10 provided, the depth of the recess preferably the thickness of the Platform 10 should correspond to form an optically clean conclusion. The platform 10 is part of a transport device to a swimming or Diving item such as a seaplane from the water onto the Outside deck 4 and vice versa.

On both sides of the transom flap 8 and thus on its starboard and port edge sections is the first rear section 6 each with a facing flap 12 and 13 provided. The two are like the transom flap 8 Facing flaps 12 and 13 shown in Figure 1 in their closed state and close essentially flush with the adjacent fuselage section and the transom flap 8. There are rails behind the facing flaps 12, 13 stowed, which are described in more detail below and also Are part of the transport device already mentioned.

In the illustrated embodiment of the ship 1 closes at the bottom A second rear section 14 at the end of the inclined first rear section 6, the top of which is a substantially horizontal surface in the manner of a platform forms and is accessible. This second rear section 14 can be different Serve purposes. This is the case for private yachts or cruise ships Tail section 14 usually as a bathing platform or so-called sea terrace used. It can also be used to enter or leave the ship be, both at sea, for example by a transfer boat on mooring second stern section 14, or in port by the second stern section 14 serves as entry and exit aid.

As can also be seen in FIG. 1, is in the exemplary embodiment shown the second rear section 14 with two fold-out so-called stair sections 16, 17 provided, folded into their rest position shown in Figure 1 are so that they are flush with the outer contour of the second rear section Complete 14. The two stair sections 16, 17 are each aligned one of the two facing flaps 12, 13 arranged and close in their Figure 1 shown rest position each formed in the first rear section 14 Recess (not shown in Figure 1).

The two stair sections 16, 17 are common, horizontal and perpendicular to the ship's longitudinal axis (not shown in the figures) Rotation axis can be swiveled by approximately 180 °. In Figure 2 are the two stair sections 16, 17 shown in their unfolded working position in which they the corresponding cutouts 18 formed in the second rear section 14, Release 19. The stair sections 16, 17 and the associated recesses 18, 19 are configured such that one in each case in the unfolded operating position continuous staircase is formed, as shown in Figure 2. In their unfolded In the operating position, the two stair sections 16, 17 are at least submerged its lower end into the water - the water surface is for the sake of Clarity not shown in the figures - so that it is the thereby formed Allow stairs from the surface of the second stern section 14 into the water and vice versa to get from the water to the second stern section 14.

The folding out of the two stair sections 16, 17 and the resultant Opening or exposing the two recesses 18, 19 is also for the Commissioning of the already mentioned transport device for recording and Exposing swimming or diving objects is important.

For the commissioning of this device, the two facing flaps must also be used 12, 13 can be opened. This is indicated in Figure 3. For this, a (in Mechanism not shown) provided mechanism that conceals within the rear section is arranged and to open a lateral movement of the facing flaps 12, 13 in one direction away from the transom flap 8.

After the two facing flaps 12, 13 are completely open, as in FIG 4, two rails 20, 22 are exposed, on either side of the transom flap 8 are arranged and parallel to each other and in the longitudinal direction of the extend inclined first rear section 6. Both rails 20, 22 the how already mentioned, are also part of the transport device, are each in one vertical plane about a common horizontal axis of rotation 23, which are perpendicular to the ship's longitudinal axis and parallel to the axis of rotation 9 of the transom flap 8 and just below the rear end of the outer deck 4. For this purpose, 4 corresponding hinges are hidden just below the outer deck arranged, on which the rails 20, 22 are hinged at their upper end. The rails 20, 22 exposed by the opened facing flaps 12, 13 are swiveled up from their rest position into their working position by a few degrees, until they are exposed by the folded-out stair sections 16, 17 Recesses 18, 19 are aligned. This state is also in FIG. 4 shown.

When the facing flaps 12, 13 are opened, not only the two Rails 20, 22 exposed, but also two slides 24, 26, each of which can be moved along a rail 20 or 22. The sledges 24, 26 can be folded in order to close the facing flaps 12, 13 to save space behind them. At rest are the carriages 24, 26, which are also part of the transport device mentioned are at the upper end of the rails 20, 22. With or after opening of the facing flaps 12, 13, the slides 24, 26 are opened. In this Position the slides 24, 26 are shown in Figure 4.

While the facing flaps 12, 13 are open, the rails 20, 22 are swung up and the slides 24, 26 are opened or after this the transom flap 8 is pivoted upwards about its axis of rotation 9, so that - viewed in the direction of travel of the ship - in front of the transom flap 8 located and below the outer deck 4 chamber 28 is opened, as shown in Figure 5. In the illustrated embodiment the bottom of this chamber 28 is flush with the surface of the second rear section 14, as can also be seen in FIG. 5. Accordingly, it extends to completely close this chamber 28 the transom valve 8 in its Closed position up to the second rear section 14 and closes with its surface sealing off (see FIGS. 1 to 4).

When the transom flap 8 is opened, the platform 10 lying thereon also becomes taken. The transom flap 8 is swung up until it is one in occupies an essential horizontal position. In this way, the one on it lying platform 10 aligned horizontally. The two slides 24, 26 arranged and designed such that the platform 10 with its two lateral projections 10a, 10b come into engagement with the slides 24, 26. For this purpose, the slides 24, 26 each have a corresponding engagement section 30 or 32 provided a releasable rigid connection or coupling with the platform 10. In this way, the platform 10 to the two carriages 24, 26 coupled so that the platform 10 is now in its horizontal Location is carried by the sled 24, 26. This condition is also in Figure 5 shown.

The transom flap 8 is then pivoted back into its closed position, so that the chamber 28 behind it is closed again, while the platform 10, now held by the sled 24, 26, in its horizontal Location remains. In this way, the platform 10 detaches from the transom flap 8 and is accordingly from its stowed position on the transom flap in your Working position spent on the sled 24, 26. This state is in Figure 6 shown.

The two rails 20, 22 are telescopic and exist in the illustrated Embodiments each of three sections, which in the in Figures 4 to 6 state shown are completely retracted.

In Figure 7, the three telescopic sections 20a, 20b, 20c and 22a, 22b, 22c of rails 20 and 22 are shown in their fully extended condition. As can be seen in FIG. 7, the individual telescopic sections 20a, 20b, 20c and 22a, 22b, 22c in the exemplary embodiment shown are approximately the same Length that corresponds approximately to the length of the first rear section 6. Here are the Rails 20, 22 with their upper sections 20a and 22a on the hull articulated while the telescopic sections 20c and 22c have their free ends form. In the illustrated embodiment, an extension of the Rails 20, 22 instead of about three times, the rails 20, 22 through the recess 18, 19 in the second rear section 14 and over the extend extended stair sections 16, 17 away. Here is the total length the rails 20, 22 dimensioned such that they with their lower telescopic sections 20c, 22c into the water (not shown in the figures) is sufficient plunge.

The platform 10 is then lifted with the aid of the carriages 24, 26 from its upper position (see FIGS. 5 to 7) along the rails 20, 22 into one lower position at the free end of the lower telescopic sections 20c, 22c Rails 20, 22 move in which the platform 10 dips into the water. This State is shown in Figure 8.

As a floating or diving object to be picked up by the platform 10 is shown in Figure 8 shows an example of a seaplane 40 that is already on the water has landed and is in a waiting position behind the stern of the ship. The Seaplane 40 is now floating on the underwater surface platform 10 is located and received by it, as in FIG. 9 is shown.

Subsequently, the seaplane 40 is removed from the water by the platform 10 lifted by the platform 10 moving upwards along the rails 20, 22 becomes. In this context it should be noted that for the movement of the sled 24, 26 a suitable drive device is provided along the rails 20, 22 is, which is however not shown in detail in the figures. This Drive device expediently has a cable drive, which is below of the upper outer deck 4 is installed inside the hull and over from him driven rope drums winds and unwinds ropes, at the free ends of which Carriage 24, 26 are attached.

The seaplane 40 taken up by the platform 10 now becomes the upper one Outer deck 4 transported by the platform 10 to the top of the Rails 20, 22 is moved where they are in alignment with the surface of the outer deck 4; the platform 10 is already in this position in FIG 7 shown.

After the seaplane 40 has been pulled onto the outer deck 4, can the transport device can be returned to its idle state by now the steps previously described with reference to FIGS. 1 to 7 and shown there essentially run in reverse order. So be first the telescopic rails 20, 22 retracted. Then the Transom flap 8 opened and already takes over in its upper position located platform 10 by being released from the carriage 24, 26 from the Transom flap in its stowed position and from this in its closed position is taken away. Then the slides 24, 26 are folded together and pivoted back the rails 20, 22 already retracted to the minimum length, before the facing flaps 12, 13 are closed, so that now the shown in Figure 2 is restored. If the stair sections 16, 17 are not otherwise needed, they are also folded back again, so that the initial state according to FIG. 1 is then reached again in the the entire device is completely covered optically.
