Description

Die Neuerung bezieht sich auf eine Ablaufvorrichtung für Frei-Fall-Rettungsboote mit einer zur Horizontalen geneigten Ablaufbahn am Heck eines Schiffes.The innovation relates to a drain device for free-fall lifeboats with a horizontal runway at the stern of a ship.

Neu gebaute Seeschiffe dürfen nur noch mit rundum geschlossenen Rettungsbooten ausgestattet werden. In Verbindung mit derartigen Rettungsbooten ist bekannt, diese am oberen Ende einer zur Horizontalen geneigten Ablaufbahn festzuzurren. Mit Hilfe einer geeigneten Auslösevorrichtung, die innerhalb des Rettungsbootes betätigt werden kann, wird die Zurrung gelöst, und das Rettungsboot rollt oder gleitet auf der Ablaufbahn entlang, um anschließend im freien Fall in das Wasser einzutauchen. Diese können mit Davits oder über eine Ablaufbahn zu Wasser gelassen werden. In Verbindung mit zuletzt bekannt, genannter ist/ am Rettungsboot vier horizontale und vertikale Rollen anzubringen, die mit der Ablaufbahn zusammenwirken. Die am Rettungsboot angebrachten Rollen stehen mehr oder weniger nach außen vor, was normalerweise sehr störend 1 ist. Der Ablaufvorgang ist ferner nicht optimal.Newly built seagoing vessels may only be equipped with lifeboats that are completely enclosed. In connection with lifeboats of this type, it is known to tie them down at the upper end of a runway inclined to the horizontal. With the help of a suitable release device, which can be operated inside the lifeboat, the lashing is released and the lifeboat rolls or glides along the runway to then dive into the water in free fall. These can be launched into the water with davits or via a runway. In connection with last known, is called / to attach to the lifeboat four horizontal and vertical roles that interact with the runway. The roles attached to the lifeboat project more or less to the outside, which is usually very annoying 1. The sequence process is also not optimal.

Es ist auch bekannt, das Rettungsboot an Gleitflächen ablaufen zu lassen. Ein Gleiten bedingt jedoch einen Reibungswinkel, der vor allem beim Verschmutzen und Korrodieren der zusammenwirkenden Gleitflächen eine erhebliche Größenordnung annehmen kann, so daß Gefahr besteht, daß bei bestimmten Lagen des Schiffes das Rettungsboot nicht mehr abgleitet.It is also known to let the lifeboat run on sliding surfaces. However, sliding requires a friction angle, which can assume a considerable order of magnitude, especially when the interacting sliding surfaces become dirty and corroded, so that there is a risk that the lifeboat will no longer slide off in certain positions of the ship.

Der Neuerung liegt die Aufgabe zugrunde, eine Ablaufvorrichtung für Frei-Fall-Rettungsboote zu schaffen, die auch bei erheblichen Schräglagen ein freies Abgleiten des Rettungsbootes gewährleistet, ohne daß am Boot störend nach außen ragende Teile vorgesehen sind.The innovation is based on the task of creating a drainage device for free-fall lifeboats, which ensures that the lifeboat slides freely even in the case of considerable inclinations, without parts which protrude outwardly from the boat being provided.

Diese Aufgabe wird neuerungsgemäß dadurch gelöst, daß die Ablaufbahn zwei parallele Reihen von Trag- und Führungsrollen aufweist mit in der Ablaufebene liegenden bzw. senkrecht zu dieser angeordneten Drehachse zwecks Zusammenwirkens mit nach unten weisenden Stützflächen bzw. seitlichen Führungsflächen am Rettungsboot.According to the innovation, this object is achieved in that the runway has two parallel rows of support and guide rollers with the axis of rotation lying in the run-off plane or arranged perpendicularly to the latter for the purpose of interacting with downward-pointing support surfaces or lateral guide surfaces on the lifeboat.

Bei einem normalen Ablauf nehmen die Tragrollen das gesamte Gewicht des Rettungsbootes auf. Die Führungsrollen dienen nur zur Führung des Bootes. Bei Schräglage des Schiffes wird das Bootsgewicht und die Führung des Bootes beim Ablauf von beiden Rollentypen übernommen.In a normal process, the idlers carry the entire weight of the lifeboat. The guide rollers only serve to guide the boat. If the ship is in an inclined position, the weight of the boat and the guidance of the boat are taken over by both types of roles.

Die Trag- und Stützrollen sind zweckmäßigerweise identisch ausgebildet und nach einer weiteren Ausgestaltung der Neuerung in wechselnder Folge angeordnet. Sie können vorzugsweise aus Kunststoff bestehen oder mit einem Kunststoffmaterial, beispielsweise Polyamid, beschichtet sein. Lediglich die unteren Trag- und Stützrollen sind nach einer weiteren Ausgestaltung der Neuerung aus korrosionsbeständigem Metall. Diese Rollen sowie ihre Lagerung sind für höhere Festigkeit ausgelegt. Nach einer weiteren Ausgestaltung der Neuerung ist vorgesehen, daß unterhalb einer nach unten weisenden Schulter auf beiden Seiten des Rettungsbootes parallele Winkelschienen angeordnet sind, die jeweils die Stütz- und Führungsfläche bilden. Die Winkelschienen sind genau parallel angeordnet und liegen oberhalb des Bootsschtwerpunktes, um ein Herausfallen des Bootes aus der Bahn bei großen Schräglagen des Schiffes (70 bis 90°) zu verhindern.The support and support rollers are expediently of identical design and arranged in an alternating sequence after a further embodiment of the innovation. They can preferably consist of plastic or be coated with a plastic material, for example polyamide. Only the lower support and support rollers are made of corrosion-resistant metal according to a further embodiment of the innovation. These roles and their storage are designed for higher strength. According to a further embodiment of the innovation it is provided that parallel angled rails are arranged below a downward-pointing shoulder on both sides of the lifeboat, each forming the support and guide surface. The angle rails are arranged exactly parallel and lie above the boat's center of gravity to prevent the boat from falling out of the way when the ship is at a large incline (70 to 90 °).

Die neuerungsgemäße Ablaufvorrichtung sorgt für ein ungehindertes Ablaufen nach Betätigung der Auslösevorrichtung auch bei extremen Schräglagen des Schiffes. Die am Schiff bzw. am Rettungsboot zutreffenden Vorkehrungen sind verhältnismäßig wenig aufwendig und bleiben auch nach längerer Zeit unter rauhesten Bedingungen funktionstüchtig.The drainage device according to the innovation ensures unimpeded drainage after actuation of the release device even in the case of extreme inclinations of the ship. The precautions applicable to the ship or lifeboat have been respected not very expensive and remain functional even after a long time under the harshest conditions.

Ein Ausführungsbeispiel der Neuerung wird nachfolgend anhand von Zeichnungen näher erläutert.

Bevor auf die in den Zeichnungen dargestellten Einzelheiten näher eingegangen wird, sei vorangestellt, daß jedes der beschriebenen Merkmale für sich oder in Verbindung mit Merkmalen der Ansprüche von neuerungswesentlicher Bedeutung ist.Before going into the details shown in the drawings, it should be assumed that each of the described features is of essential importance for innovation either alone or in conjunction with features of the claims.

Aus den Figuren 1 und 2 ist ersichtlich, daß außerhalb der Längsmitte am Heck eines Schiffes 10 eine allgemein mit 11 bezeichnete Ablaufvorrichtung angeordnet ist. Ein rundum geschlossenes Rettungsboot 12 wird normalerweise an der Ablaufvorrichtung 11 festgezurrt. Beim Lösen der Verriegelung bewegt sich das Boot in der eingenommenen geneigten Lage abwärts, um im freien Fall in das Wasser einzutauchen. Einzelheiten der Ablaufvorrichtung gehen aus den Figuren 3 bis 5 hervor.It can be seen from FIGS. 1 and 2 that, outside the longitudinal center at the stern of a ship 10, a generally 11 designated drain device is arranged. A completely enclosed lifeboat 12 is normally lashed to the drain device 11. When the lock is released, the boat moves downwards in the inclined position to dive into the water in free fall. Details of the drain device can be seen in FIGS. 3 to 5.

Die Ablaufbahn der Ablaufvorrichtung 11 weist zwei parallele Träger 13, 14 auf, die durch beabstandete Querträger 15, 16 starr miteinander verbunden sind. Der Querträger 18 ist U-förmig, um Platz für die Unterseite des Bootes 12 zu schaffen. Die Träger 13, 14 sind in einer Ebene angeordnet, welche etwa in einem Winkel von 30° zur Horizontalen verläuft. Mit Hilfe von Lagerzapfen 17 sind an der Innenseite der Träger 13, 14 Tragrollen 18 drehbar gelagert. Annähernd mittig zwischen dcn einzelnen Tragrollen 18 sind Führungsrollen 19 angeordnet mit senkrecht zur Ebene der Träger 13, 14 angeordneten Drehachsen. Der Abstand zwischen den Rollen 18, 19 beträgt etwa 0,5 m. Die Rollen 17, 18 sind aus einem Kunststoff, zum Beispiel Polyamid. Lediglich die letzten beiden Rollen auf jeder Seite der Träger 13, 14 sind aus korrosionsbeständigem Metall, beispielsweise Bronze. Sie sind auch in ihrer Lagerung stabiler ausgelegt als die übrigen.The runway of the runoff device 11 has two parallel supports 13, 14 which are rigidly connected to one another by spaced-apart cross supports 15, 16. The cross member 18 is U-shaped to make room for the underside of the boat 12. The carriers 13, 14 are arranged in a plane which extends approximately at an angle of 30 ° to the horizontal. With the help of bearing pins 17, 14 support rollers 18 are rotatably mounted on the inside of the carrier. Guide rollers 19 are arranged approximately centrally between the individual support rollers 18 with axes of rotation arranged perpendicular to the plane of the supports 13, 14. The distance between the rollers 18, 19 is approximately 0.5 m. The rollers 17, 18 are made of a plastic, for example polyamide. Only the last two rollers on each side of the carrier 13, 14 are made of corrosion-resistant metal, for example bronze. They are also more stable in their storage than the rest.

Aus Fig. 5 läßt sich die Abstützung bzw. Führung des Rettungsbootes 12 auf einer Seite der Ablaufbahn erkennen. Unterhalb einer sich in Längsrichtung erstreckenden Schulter 20 unterhalb der Scheuerleiste des Bootes 12 ist eine Winkelschiene 21 angebracht. Die Außenseiten der Schenkel der Winkelschiene 21 bilden eine Stützfläche 22 bzw. eine Führungsfläche 23. Sie treten entsprechend mit den Tragrollen 18 bzw. den Führungsrollen 19 in Eingriff. Die Drehzapfen 17 bzw. 24 der Trag- und Führungsrollen 18, 19 sind an der Außenseite des Trägers 14 in geeigneter Weise befestigt. Die Winkelschiene 21 oder allgemein die Führungsflächen sind mithin unterhalb der Scheuerleiste des Bootes geschützt untergebracht. Sie bilden im übrigen mit der Scheuerleiste einen Längsverband. Es versteht sich, daß statt der Winkelschiene eine andere geeignete Verstärkung der Stütz- und Führungsflächen an dieser Stelle gewählt werden kann.5 shows the support or guidance of the lifeboat 12 on one side of the runway. Below An angled rail 21 is attached to a longitudinally extending shoulder 20 below the rubbing strake of the boat 12. The outer sides of the legs of the angle rail 21 form a support surface 22 or a guide surface 23. They accordingly engage the support rollers 18 or the guide rollers 19. The pivots 17 and 24 of the support and guide rollers 18, 19 are attached to the outside of the carrier 14 in a suitable manner. The angle rail 21 or generally the guide surfaces are therefore protected under the rubbing strake of the boat. They also form a longitudinal bond with the rubbing strake. It goes without saying that instead of the angle rail, another suitable reinforcement of the support and guide surfaces can be selected at this point.

Es versteht sich ferner, daß die Abstützung und Führung des Bootes 12 auf der anderen Seite in gleicher Weise erfolgt.It is further understood that the support and guidance of the boat 12 is carried out in the same way on the other side.

Wie ersichtlich, nehmen beim normalen Ablauf die Tragrollen 18 das gesamte Gewicht des Bootes 12 auf. Die Führungsrollen dienen lediglich zur seitlichen Führung des Bootes 12. Bei einer Schräglage des Schiffes 10 wird das Bootsgewicht und die Führung des Bootes 12 von beiden Rollen 18, 19 übernommen.As can be seen, the carrying rollers 18 take up the entire weight of the boat 12 during normal operation. The guide rollers serve only for lateral guidance of the boat 12. When the ship 10 is in an inclined position, the weight of the boat and the guidance of the boat 12 are taken over by both rollers 18, 19.

Als unterste Rollen sind Führungsrollen 19 vorgesehen, die zudem nahe an der benachbarten Tragrolle 18 angeordnet sind, wie aus Fig. 3 und 4 deutlich zu erkennen. Es wird dadurch verhindert, daß sich bei schräg liegendem Schiff und/oder langsam ablaufendem Boot dieses in der Bahn verkeilt.Guide rollers 19 are provided as the lowest rollers, which are also arranged close to the adjacent support roller 18, as can be clearly seen from FIGS. 3 and 4. This prevents the boat from wedging in the course when the ship is at an angle and / or the boat is slowly running.
