Abstract

Die Erfindung bezieht sich auf eine Befestigungseinrichtung fuer Seenotrettungsvorrichtungen auf Schiffen, die sich im Havariefall automatisch loest. Das Ziel der Erfindung ist, dass das Loesen der Seenotrettungsvorrichtung in jedem Falle sicher erfolgt. Da das Loesen abhaengig von der Funktion des Wasserdruckausloesers ist, besteht die Aufgabe darin, die durch die Verzurrung am Druckbolzen des Wasserdruckausloesers anliegende Reibkraft erheblich zu vermindern. Die Loesung liegt darin, dass an dem Druckbolzen ein verlaengerter Teil eines gekruemmten Spannhebels anliegt, der um eine Drehachse an seinem stark gekruemmten Teil schwenkbar ist und an dessen Kruemmung die Vorspannkraft des Zurrgurtes der Seenotrettungsvorrichtung angreift. Anzuwenden ist die Erfindung auf Schiffen bei der Lagerung von Rettungsfloessen, -booten oder aehnlichem. FigurThe invention relates to a fastening device for maritime rescue devices on ships, which automatically loosen in the event of an accident. The aim of the invention is that the loosening of the maritime rescue device takes place safely in any case. Since the Loesen is dependent on the function of the water pressure release, the task is to significantly reduce the frictional force applied by the lashing on the pressure pin of the water pressure release. The solution lies in the fact that on the pressure pin an extended part of a curved clamping lever rests, which is pivotable about an axis of rotation at its strongly curved part and acts on the Kruemmung the biasing force of the lashing of the Lifeline rescue device. Applicable is the invention on ships in the storage of Rettungsfloessen, boats or the like. figure

Diese erfindungsgemäß auf einem Schiff installierte Einrichtung löst mit Sicherheit beim Sinken des Schiffes automatisch die Verzurrung der Seenotrettungsvorrichtungen, denn der Hauptanteil der Vorspannkraft und der Auftriebskraft wird über den Spannhebel in die Halterung und Lagerung geleitet, während nur ein geringer Kraftanteil am Druckbolzen des Wasserdruckauslösers anliegt und so dessen sichere Funktion gewährleistet.This inventively installed on a ship device solves with security when sinking the ship automatically the lashing of the lifesaving devices, because the majority of the biasing force and the buoyancy force is passed over the clamping lever in the holder and storage, while only a small proportion of force applied to the pressure pin of the water pressure release and thus ensuring its safe function.

,Ausführungsbeispiel, Embodiment

Die Erfindung soll anschließend an Hand eines Ausführungsbeispieles näher erläutert werden. Die zugehörige Zeichnung zeigt schematisch den automatisch wirkenden Auslösemechanismus in Seitenansicht.The invention will be explained in more detail with reference to an embodiment. The accompanying drawing shows schematically the automatically acting trigger mechanism in side view.

An einer als Floßklampe ausgebildeten Lagerung 1 einer Seenotrettungsvorrichtung ist an einem Querträger ein Wasserdruckauslöser 9 befestigt. Seitlich ist eine rechtwinklige Halterung 11 zu erkennen, die eine Drehachse (2) trägt. An diese Drehachse 2 ist ein relativ langer, gekrümmter Spannhebel 4 angelenkt, dessen Krümmungsradius in Richtung Drehachse 2 stark abnimmt. Durch diese Formgebung wird die in der Krümmung angreifende Kraft in einem hohen Prozentsatz über die Drehachse 2 in die Halterung 11 und Lagerung 1 geleitet, während an dem langen schmalen Teil des Spannhebels 4 nur eine stark geminderte Kraft zur Wirkung kommt. In der Krümmung des Spannhebels 4 greift über einen Schäkel 8 die Vorspannkraft des Zurrgu rtes 3 der Seenotrettungsvorrichtung an. Dadurch drückt der lange schmale Teil des Spannhebels 4 mit stark geminderter Kraft an den Druckbolzen 10 des Wasserdruckauslösers 9. Dadurch, daß nicht mehr der volle Kraftanteil am Druckbolzen 10 anliegt, bleibt der Wasserdruckauslöser 9 voll wirksam. Um den Spannhebel 4 ist außerdem leicht lösbar die Reißleine 5 geschlungen, die in ihrem weiteren Verlauf durch ein Auge 7 geführt wird, das an der Lagerung 1 angebracht ist, damit die Zugkraft auf den Spannhebel 4 immer von einer Seite erfolgt, mit der Reißleine 5 ist die Sollbruchleine 6 verbunden, die an dem Auge 7 befestigt ist.On a designed as raft cleat storage 1 a maritime rescue device, a water pressure trigger 9 is attached to a cross member. Laterally, a rectangular bracket 11 can be seen, which carries a rotation axis (2). At this axis of rotation 2, a relatively long, curved clamping lever 4 is articulated, the radius of curvature in the direction of rotation axis 2 decreases sharply. By this shaping, the force acting in the curvature is passed in a high percentage on the axis of rotation 2 in the holder 11 and storage 1, while on the long narrow part of the clamping lever 4 only a greatly reduced force comes into effect. In the curvature of the clamping lever 4 engages over a shackle 8, the biasing force of Zurrgu rtes 3 of the maritime rescue device. As a result, the long narrow part of the clamping lever 4 presses with greatly reduced force on the pressure pin 10 of the water pressure release 9. Due to the fact that not the full force component is applied to the pressure pin 10, the water pressure release 9 remains fully effective. To the clamping lever 4 is also easily releasably looped the ripcord 5, which is guided in its further course by an eye 7, which is attached to the storage 1, so that the pulling force on the clamping lever 4 is always done from one side, with the ripcond fifth the predetermined breaking line 6 is connected, which is fastened to the eye 7.

Gerät diese Einrichtung mit dem sinkenden Schiff etwa 2-4m unter die Wasseroberfläche und sie ist vorher noch nicht von Hand ausgelöst worden, so drückt sich der Druckbolzen 10 in den Wasserdruckauslöser 9 und gibt automatisch den Spannhebel 4frei. Dieser schwenkt um die Drehachse 2 und läßt die Reißleine 5 und den Schäkel 8 mit dem Zurrgurt 3 frei, so daß die Seenotrettungsvorrichtung aufschwimmen kann. Durch die Verbindung der Reißleine 5 mit dem Auge 7 über die Sollbruchleine 6 kann z. B. das Rettungsfloß durch den Zug sich selbständig aufblasen, bleibt aber im Bereich des Schiffes. Nach weiterem Sinken des Schiffes wird die Verbindung mit der Seenotrettungsvorrichtung selbständig unterbrochen bzw. nach deren Besteigung durch die Mannschaft gekappt.Device this device with the sinking ship about 2-4m below the water surface and it has not previously been triggered by hand, so pushes the pressure pin 10 in the water pressure release 9 and automatically gives the clamping lever 4frei. This pivots about the axis of rotation 2 and leaves the ripcord 5 and the shackle 8 with the lashing belt 3 free, so that the maritime rescue device can float. By connecting the ripcord 5 with the eye 7 on the predetermined breaking line 6 z. B. the life raft by the train inflate independently, but remains in the range of the ship. After further sinking of the ship, the connection with the maritime rescue device is automatically interrupted or capped after their ascent by the team.

Field of application of the invention

The invention relates to a device for attachment of maritime rescue devices on ships, which automatically releases one or more maritime rescue devices at the sinking of the ship by means of a water pressure release. It is therefore to be used on ships to ensure adequate rescue equipment in case of emergency.

Characteristic of the known technical solutions

Due to the practice of having sufficient rescue equipment for the crew and the passengers on ships in distress, it is necessary to have several lifeboats in the form of lifeboats, inflatable boats or rafts on board. These must be lashed securely on deck to withstand normal seaborne movements. On the other hand, the secure lashing must solve automatically in distress and release the maritime rescue devices. Has proved useful for a water pressure trigger, as described in TGL 25829/02, in which a membrane is pressed into the interior when sinking the ship in a certain depth of water and thereby takes the pressure pin, which unlocks the lashing and the lifesaving device can float. Due to the high forces occurring in the lashing sometimes occurs on the pressure pin on such a large friction that this is dysfunctional and does not release the lashing. To reduce the forces occurring at the water pressure trigger, one is for example striving for DD 128770. Thereafter, the leash of the liferaft is attached via a lashing over a very particular shaped eyelet hook on the water pressure trigger. The linen force engages above a pivot point of the Ösenhakens, so that only a relatively small force acts on the release hook, whereby the triggering is guaranteed. The necessary parts are very expensive to manufacture and affect their function under extreme weather conditions. The lashing of the maritime rescue device itself is done in a conventional manner. In particular, if two lifeguards are connected via a lashing on a water pressure release, the problems described above occur more frequently.

Object of the invention

The invention has the goal that in case of distress the existing maritime rescue devices are safely automatically separated from the sinking ship and thus ready to accommodate the people to be rescued.

Explanation of the essence of the invention

Based on the disadvantages of the known and currently often used Rettungsmittelverzurrungen a water pressure trigger on the boat deck, it is an object of the invention to provide an automatic release device for maritime rescue devices, which greatly reduces the frictional force occurring at the pressure pin of the water pressure release and thus ensures a safe function of the water pressure trigger. The achievement of this object is that the lashing for the attachment of one or more lifesaving devices via a shackle in the strongly curved portion of a clamping lever attacks whose radius of curvature in the direction of a rotation axis, where it is articulated with the shorter side seen from the shackle, decreases sharply, while the longer free end of the clamping lever with reduced pressure force on the pressure bolt of a water pressure trigger is designed to be pressing, wherein the axis of rotation is arranged at a certain distance from and parallel to the pressure pin of the water pressure release by a bracket to the support of the maritime rescue device. According to another feature, the ripcord wrapped around the cocking lever is guided by an eye mounted on the bearing while the rupture line connected to the ripcord is attached to this eye.
