Field of application of the invention

The invention is to be applied to the storage and deployment of ready boats and rotting boats in the immediate vicinity of the squat, so that they can be used for launching the boats. Applicable is the invention so on such ships, which are functionally equipped with a Hockaufschloppe.

Characteristic of the known technical solutions

When storing lifeboats on ships, it is always important that they are as soon as possible in the ready position or fully occupied can be launched into the water and get away from the ship. These are known by gravity Javits hanging lifeboats that can be left on the side of the ship into the water. A development of recent times are the so-called free-fall boats, the full bouncing over the sides of the ship or bouncing freely from the stern on the water. A condensed summary of the currently known various variants of facilities for the suspension of freefall boats is in the Yearbook of the Shipbuilding Engineering, Bd, 78 (1984) p. 67ff. released. There you can see sloped runways and davits for freefall boats. Also freefall boats are described in arrangement and function. Another free-fall boat is shown and explained with its runway at the rear of a freighter. All diene facilities can not be used in their shape and arrangement on fishing pens with Heckaufschleppe, since the Heckspiegol and the adjoining area with fishing and general equipment is occupied. In addition, the impact on the water for the crew has been proven to be associated with increased stress, resulting in the omission of trial maneuvers. So far, the heeling of the vessel is of great influence for the safe removal of the lifeboat.

Object of the invention It is the object of the invention to increase the safety of the crew on fishing vessels through optimal storage and

irrigation-independent as well as relatively woichos inlet of rotting boats, taking advantage of the features of a fishing tail.

Explanation of the essence of the invention Based on the described Nachtoile ι the known devices for suspending boats of damaged It is the object of the invention of ships to provide a solution for Flscf fishing vessels which meets today's requirements To offer rear towing with stored mechanical energy, watering and removing the To ensure lifeboats from the ship. The solution of this task according to the invention says, dalj immediately before and laterally the Heckaufschleppe on the Ship deck a substructure is arranged for a pivoting about 180 ° pivoting Tragachale, wherein the tray

for the boat by the tilted in the swung-out position on the pivot column elno inclined extension of

Heckaufschlopppu for Zuwaseerglelten the boat represents. According to another feature, the height of the substructure above the ship deck is half the length of the boat and is

above the rear inner pillar of the substructure the pivot pillar - consisting of the foot bearing, the center bearing and dom

Head bearing piece arranged, wherein between the foot bearing and the center bearing to oino vertical axis a cross bearing block

is inserted, in which a horizontal axis of the tray ßolagon i »l.

After again another feature, the Tragschalo the main frame shape of the boat and preferably three quarters

the length thereof, wherein the horizontal axis is fixed in a Querwulct, while in the upper extension direction of the

Vertikalachso in a neck of the Querwulst a fingerstall is inserted, which after pivoting the tray into the Aussotzstellung is unlatched from the slot bearing of the head bearing piece. According to a further feature of the invention are on the tray two double ribs, each with a Hebelklauo the Gunwale of the boats arranged comprehensively, one attached via a drawstring on the pivot column wedge the Lever claws until tipping of the tray arresting and then releasing is present. According to yet another feature, the vertical axis is to be operated by a from the interior of the boat to be actuated Stößol put into operation settable pivoting operation, with a mounted on the pivot column manual valve of the Pressure medium storage is arranged adjustable by the plunger. If this boat launch device in case of accident in function, so the following steps are provided: The crew goes in

the interior of the boat provided on the substructure. If the boat is occupied, enter from inside with the help of a pestle

Hand-operated valve actuated. With the help of the opened Duckmittelspelchers there is a pivoting of the boat with the tray

180 ° directly behind the stern. At about 180 ° locked independently a fingerstall, the tipping of the

Boat in an inclined position, which is equivalent to the extension of the rear towing. At the same time, the wedge rail releases the Lever claws, whereby the boat slides due to the force of gravity on the Heckaufschleppe into the water. By the

The impulse floats the boat just a bit away from the scuff.

Ausführungsbelsplel

The invention will be explained in more detail with reference to a boat suspension device, as shown in the drawings. Show in detail

Fig. 1: the longitudinal section of a ship with Heckaufschleppe with BootsausseUeinrlchtung in dumped position Fig. 2: The top view of the ship with Heckaufschleppe with Bootsaussetzeinrichtung in rest position Fig. 3: the cross section through the boat in the tray 4 shows the cross section through the boat swung through 180 ° from the rest position Fig. 5: an illustration of the slit bearing and Fig. 6: the cross bearing block with the two axes.

In order to be able to expose a lifeboat over the stern of a fishing vessel, it must be arranged as close as possible to the transom. However, since this area is necessarily occupied by fishing equipment, storage is only possible immediately in front of the rear tug 3 in the lateral area. In order to then allow the suspension of the rear tug 3, pivoting from the rest position is required. Fig. 1 and Fig.2 show the Lagorung a boat in the aft area. For this purpose, a substructure 1 with a pivoting column 5 and a Tragscr ale 4 for the boat β is constructed on the ship's deck 2. In Fig. 1, the support shell 4 is shown with the boat 6 in swung, tilted position, while the rest position by 4 ', 6' is shown. 2, the swung-out position is outlined by 4 "The boat 6 is held in the carrying frame 4 with two lever claws 19, which clasp the gunwale 20 and are mounted in a double rib 18. The lever claws 19 are tensioned by a wedge rail 21, which is connected via a drawstring 22 with the pivoting column 5. The pivoting column 6 is located on dam inner, rear post 7 of the substructure 1. Below the pivoting column 5 is the pivoting operation 23, dor by means of a manual overflow valve 25 via the accumulator 24 in The pivot column 5 itself consists of the Fußlagor 8, the center bearing 9 and the head bearing piece 10, wherein between Fußlager 8 and center bearing 9 about a vertical axis 11, a cross bearing block 12 is inserted, in which a horizontal axis 13 of the support shell is located is held in a transverse bead 14 of the support shell 4. In the extension direction of the vertical axis 11, the quill bead is inserted in a projection 16 14 a fingerstall 15 which is guided in a slot bearing 17 of the head bearing piece 10 so that it disengages after pivoting of the support shell 4 by 180 ° from the slot bearing 17, whereby the tilting of Fig. 1 is effected. The height of the substructure 1 corresponds to about half the length of the boat 6, the length of the tray 4 about three quarters of the length of the boat 6. It is designed so that it corresponds to the main frame shape of the boat 6, at risk, the boat 6 in the position Join in Fig. 2. From the interior, the manual control valve 25 is actuated via a plunger 26, thereby initiating the pivoting process. After swiveling through 180 °, the position 4 "In Flg. 2 is reached

In this position, the fingerstall 15 reaches the position of FIG. C in the centering position 17, whereupon it disengages and tilts the boat β into the position of FIG. This has been solved by the attachment of the wedge rail 21 übor the drawstring 22 on the Schwonksäulo 6 Hebolklauon 19 from the boat 6 and the boat 6 slips due to the force of gravity on the Heckaufschloppe 3 relatively welch in the Watt, _ol and so with elnom pulse that it immediately leaves the ship. If the boat is only exposed from maneuvering, it is relatively easy to recover the boat by means of the available tipping runners and tipping winches via the squat in the swung-out gokippte carrying tray.
