Description

Beim Auslösen des Aufblasvorganges bilden sich an der der Hochdruckflasche gegenüberliegenden Seite durch die symmetrische Faltung sowie die Lage der Mündungen der Hochdruckschläuche in die Tragschläuche zwei Gaspolster, die sich aufeinander abstützen. Der feste Verschlußstreifen, der die Halbschalen des Behälters an der Kante im Bereich der Hochdruckflasche verbindet, wirkt entsprechend einem Scharnier, während die übrigen die Sollbruchstelle bildenden Verschlußstreifen gesprengt werden. Auf diese Weise wird die Funktionssicherheit des Aufblasvorganges erhöht, wobei die Lagerung der Druckgasflasche eine eindeutige Schwerpunktlage im Bereich des als Scharnier wirkenden Verschlußstreifens ergibt. Dadurch und durch die analoge symmetrische Faltung des Rettungsfloßes ist nur ein Aufblasen in richtiger Schwimmlage möglich. Die Druckgasflasche ist beim Entfalten am Drehpunkt gelagert, weshalb keine Gefährdung der im Wasser schwimmenden Personen hervorgerufen wird.When the inflation process is initiated, two gas cushions, which are supported on one another, form on the side opposite the high-pressure bottle due to the symmetrical folding and the position of the mouths of the high-pressure hoses in the support hoses. The fixed closure strip, which connects the half-shells of the container at the edge in the region of the high-pressure bottle, acts according to a hinge, while the other sealing strips forming the predetermined breaking point are burst. In this way, the reliability of the inflation process is increased, the storage of the compressed gas cylinder results in a clear center of gravity in the region acting as a hinge closure strip. As a result, and by the analog symmetrical folding of the life raft only inflation in proper swimming position is possible. The compressed gas cylinder is stored at the fulcrum when unfolding, which is why no danger to the people floating in the water is caused.

Die beiden Halbschalen 1 und 2 sind an drei Seiten mit einem Verschlußstreifen 3 mit Sollbruchstelle und an der vierten seite mit einem Verschlußstreifen 4 ohne Sollbruchstelle verbunden. Im Bereich des Verschlußstreifens 4 ist an der Floßbodenunterseite 15 die Hochdruckflasche 9 verschiebbar angeordnet, wodurch eine eindeutige Schwerpunktlage in diesem Bereich erzielt wird. Das Floß ist ausgehend von der in der Symmetrieachse gelagerten Hochdruckflasche 9 symmetrisch nach innen gefaltet. Die Notausrüstung 13 liegt im verpackten Zustand im Innern des Rettungsfloßes an der Hochdruckflasche 9. Durchziehen an der Reißleine 11 wird durch die Auslösevorrichtung 12 ein Ventil der Hochdruckflasche 9 geöffnet. Über die Hochdruckschläuche 5 und 6 und über die Einlaßventile 14 strömt das Füllmedium in die Tragschläuche 7 und 8. Die Einlaßventile 14 sind nach beiden Seiten in gleichem Abstand von der Auslösevorrichtung 12 in den Tragschläuchen 7 und 8 angebracht. Der Abstand beträgt mindestens ³A und höchstens 1¹A der Breite a des Verpackungsbehältnisses. Im Bereich der Einlaßventile 14 bilden sich in den Tragschläuchen 7 und 8 zwei sich aufeinander abstützende Gaspolster. Der Verschlußstreifen mit Sollbruchstelle 3 wird längs zerstört und die jeweils oben liegende Halbschale 1 oder 2 klappt scharnierartig auf. Das Rettungsfloß bläst sich anschließend in aufrechter Schwimmlage auf. Dabei wird die Hochdruckflasche 9 in Richtung der Symmetrieachse bis zur äußeren Begrenzung des Rettungsfloßes aus der Flaschenhalterung 10 gezogen. Die Flaschenhalterung 10 besitzt U-förmigen Querschnitt und ist an beiden Stirnseiten offen. Im verpackten Zustand nimmt die Hochdruckflasche 9 die in Fig.4 gestrichelt dargestellte Lage ein. Die Hochdruckflasche 9 ist in ihrer Endstellung zusätzlich durch lose Schnuren gehalten, die ihrerseits mit der Flaschenhalterung 10 verbunden sind.The two half-shells 1 and 2 are connected on three sides with a closure strip 3 with predetermined breaking point and on the fourth side with a closure strip 4 without predetermined breaking point. In the region of the closure strip 4, the high-pressure bottle 9 is slidably disposed on the raft bottom bottom 15, whereby a clear center of gravity position is achieved in this area. The raft is symmetrically folded inwards starting from the high-pressure bottle 9 mounted in the axis of symmetry. The emergency equipment 13 is in the packaged state inside the life raft on the high pressure bottle 9. Pulling on the ripcord 11 is opened by the triggering device 12, a valve of the high pressure bottle 9. About the high pressure hoses 5 and 6 and the inlet valves 14, the filling medium flows into the support hoses 7 and 8. The inlet valves 14 are mounted on both sides at the same distance from the triggering device 12 in the support hoses 7 and 8. The distance is at least ³ A and at most 1 ¹ A of the width a of the packaging container. In the area of the intake valves 14, two gas pillows which are supported on one another and form in the support hoses 7 and 8 are formed. The closure strip with predetermined breaking point 3 is longitudinally destroyed and the respective top half shell 1 or 2 folds hingedly. The life raft then inflates in an upright swimming position. In this case, the high-pressure bottle 9 is pulled in the direction of the axis of symmetry to the outer boundary of the life raft from the bottle holder 10. The bottle holder 10 has a U-shaped cross-section and is open at both ends. In the packaged state, the high pressure bottle 9 assumes the position shown in dashed lines in Figure 4 a. The high-pressure bottle 9 is additionally held in its end position by loose strings, which in turn are connected to the bottle holder 10.

Field of application of the invention

The invention relates to an inflatable life raft, which is packaged in a rigid suitcase-like container and is preferably provided for the rescue of human life in distress on yachts

Characteristic of the known technical solutions

It is known to pack inflatable life rafts in cylindrical or cuboid containers While the cylindrical or barrel-shaped containers are used on ocean-going vessels which have the corresponding brackets, the life-saving rafts are primarily on yachts due to the storage facilities on board and for aesthetic reasons packaged suitcase-like containers

So far, it is generally assumed that, regardless of the container shape, the raft is rolled or folded from one side The compressed gas cylinder stored at the end of the roll parallel to the lower buoyancy hose In this way, a certain center of gravity should be achieved to ensure inflation in proper swimming position However, 100% security can not be achieved in this way

By the construction described in DD-PS 131246 a liferaft with ground reinforcements, this safety is further increased by usually works in both possible floating situations, the overhead stiffening out However, the center of gravity is not completely clearly defined by the emergency equipment, especially if this, beweg Β According to customer wishes, reduced When the sea is moving, it is not completely impossible to inflate in an inverted swimming position. Furthermore, persons already floating in the water during the inflation process may be endangered by the pressure cylinder attached to the entrance during the deployment of the life raft

Object of the invention

The aim of the invention is the construction of an inflatable life raft, which guarantees inflation in proper swimming position and excludes a danger of drowning in the water persons during deployment

Essence of the invention

The technical object of the invention is then to provide a packaged in a rigid suitcase-like container inflatable life raft, which occupies a clear focus position in the water and unfolds safely and defined during inflation, with only flexible parts to be moved

According to the invention, this object is achieved in that the high-pressure bottle used to hold the filling medium is arranged in the symmetry axis of the raft floor at the raft bottom. It is displaceable in the ventilated state of the raft in the direction of the symmetry axis. The raft is symmetrically folded inwards starting from this symmetry axis patronize to both sides at the same distance from the Auslosevorrichtung on the high pressure cylinder into the supporting hoses This distance corresponds at least ³ a, at most, however, 1 ¹ a, the width a of the half-shells of Verpackungsbehalters These half-shells are one at the edge at which the high-pressure bottle superimposed with fixed closure strip and connected to the other 3 edges with closure strip with predetermined breaking point
