Description

Neuartiges Aufblassystem für aufblasbare Rettungswesten.Novel inflation system for inflatable life jackets.

Die Erfindung bezieht sich auf ein neuartiges Aufblassystem für aufblasbare Rettungswesten, bei dem der Öffnungsmechanismus zum Öffnen eines Gasreservoirs zum Aufblasen der Rettungsweste mit dem Behälter des Gasreservoirs fest miteinander verbunden ist und als Einheit mit einer Aufnahme an der Rettungsweste verbunden wird und das Gas beim Öffnen des Gasreservoirs durch eine Öffnung am Aufnahmeteil in die Rettungsweste strömen kann und die Rettungsweste durch Expansion des verwendeten Gases zur Verwendungsgröße aufbläst.The invention relates to a innovative inflation system for inflatable life jackets, in which the opening mechanism for opening a gas reservoir to inflate the life jacket with the container of the gas reservoir is connected to each other and as a unit with a recording on the Life jacket is connected and the gas by opening the gas reservoir an opening on Receiving part can flow into the life jacket and the life jacket inflates to the size of use by expansion of the gas used.

Es sind Aufblassysteme bekannt, die ein Gasreservoir aus Metall öffnen, welches CO2-Gas bevorratet, das unter sehr hohem Druck eingeschlossen und gasdicht nach dem Füllen des Gases in das Reservoir mit einer Metallmembrane verschweißt ist. Diese Reservoirs müssen hohe Drücke aushalten, die bei Lagertemperaturen von z. B. 70° C bis 200 bar auftreten können. Um diese Reservoirs zu öffnen, werden kleine Metalldorne durch die Verschlußmembran gedrückt. Auch hierzu sind hohe Kräfte bis über 300 N erforderlich. Diese Öffnungskraft wird beim manuellen Aufblassystem über Hebelmechanismen erreicht. Diese Art Öffnungsmechanismen haben eine Aufnahme, in die durch ein Gewinde, welches sich am Hals des patronenartig geformten Gasreservoirs befindet – im folgenden Patrone genannt -, eingeschraubt werden. Diese Mechanismen sind aufwendig gestaltet, so muß z. B. der Metalldorn zum Öffnen der Patrone aus gehärtetem nichtrostenden Stahl gefertigt werden und muß seine scharfen Kanten an der Eindringseite für mehrere Anwendungen behalten. Diese Systeme sind vielfach auch mit einer Vorrichtung versehen, die den Öffnungsmechanismus automatisch bei Kontakt mit Wasser in Betrieb setzen. Diese Ausführungen werden als sog. ohmachtsichere Öffnungsmechanismem bezeichnet. Hier sind vorgespannte Druckfedern integriert, die auf den Metalloldorn wirken. Die Kraft der Feder wird durch ein Sperrelement gesteuert, das bei Berührung mit Wasser die Kraft der Feder freigibt zum Öffnen der Patrone mittels des Dorns.Inflation systems are known which open a metal gas reservoir, which stores CO2 gas, which is trapped under very high pressure and gas-tight after filling the gas is welded into the reservoir with a metal membrane. This Reservoirs have to high pressures endure that at storage temperatures of z. B. 70 ° C to 200 bar can occur. To be able to open these reservoirs small metal spikes are pushed through the sealing membrane. Also there are high forces for this to over 300 N required. This opening force is achieved with lever mechanisms in the manual inflation system. This kind of opening mechanism have a receptacle in which a thread that is on the neck of the cartridge-shaped gas reservoir is located in the following Cartridge called -, screwed. These mechanisms are elaborately designed, z. B. the metal mandrel to open the cartridge from hardened stainless steel must be manufactured and must have its sharp edges the penetration side for keep multiple applications. These systems are often included a device that automatically opens the mechanism Put into contact with water. These versions are called the so-called non-power-safe opening mechanism designated. Preloaded compression springs are integrated here work the metal mandrel. The force of the spring is controlled by a locking element controlled that when touched with Water releases the force of the spring to open the cartridge by means of the Mandrel.

Diese Öffnungsmechanismen sind aufwendig und teuer in der Herstellung. Es kann auch zu Fehlbedienung kommen. So ist das Öffnungsloch an der Patrone klein und beim Auswechseln der leeren gebrauchten Gaspatrone kann es Verwechslungen geben, so dass unmerklich eine schon verwendete Patrone wieder eingeschraubt wird. In der Praxis wird für die Lebensdauer der Rettungsweste zwei- oder dreimal die Patrone ausgetauscht. Die Herstellkosten der Patrone stehen von daher im Vergleich zum Öffnungsmechanismus im Mißverhältnis.These opening mechanisms are complex and expensive to manufacture. Incorrect operation can also occur. That's the opening hole small on the cartridge and when replacing the empty used ones Gas cartridge can be confused, so imperceptibly one already used cartridge is screwed in again. In practice is for the life of the life jacket two or three times the cartridge replaced. The manufacturing costs of the cartridge are therefore in Comparison to the opening mechanism out of proportion.

Aufgabe der vorliegenden Erfindung ist es, die oben genannten Nachteile der bekannten Systeme zu vermeiden und durch ein in der Wirkungsweise und in der Anwendung einfaches, sicheres, neues, kostengünstiges Aufblassystem zu schaffen.Object of the present invention is to avoid the above-mentioned disadvantages of the known systems and through a simple operation and application, safe, new, inexpensive To create inflation system.

Die Erfindung wird anhand eines Ausführungsbeispiels (16) näher beschrieben. 1 zeigt eine Rettungsweste (1) mit dem Öffnungssytem (2), welches mit einem Band (3), an dem ein Griffring befestigt ist, manuell betätigt wird. Diese Westen haben zusätzlich einen sog. Mundaufblasschlauch (4) für eventuelle Misfunktion des Öffnungsmechanismus. Das ist hier nicht relevant. 2 zeigt skizzenhaft die Einheit der Patrone (5) mit dem fest verbundenem Öffnungsmechanismus (6), einen manuell zu bedienenden Hebel (7) und Ausnehmungen (8) für die Befestigung am Aufnahmeteil. 3 zeigt einen Ausschnitt der Schwimmweste (9) mit dem Aufnahmeteil (10), der Einraststege (11) und dem Eintrittsloch (12) zur Schwimmweste. Die einfache Befestigungsart der Patrone mit dem Öffnungsteil an die Aufnahme ist gut zu ersehen.The invention is based on an embodiment ( 1 - 6 ) described in more detail. 1 shows a life jacket ( 1 ) with the opening system ( 2 ), which with a band ( 3 ), to which a grip ring is attached, is operated manually. These vests also have a so-called mouth inflation tube ( 4 ) for possible malfunction of the opening mechanism. That is not relevant here. 2 shows a sketch of the cartridge unit ( 5 ) with the firmly connected opening mechanism ( 6 ), a manually operated lever ( 7 ) and recesses ( 8th ) for attachment to the receiving part. 3 shows a section of the life jacket ( 9 ) with the receiving part ( 10 ), the snap bars ( 11 ) and the entry hole ( 12 ) to the life jacket. The simple way of attaching the cartridge with the opening part to the holder is clearly visible.

4 zeigt das Öffnungssytem, das im Gebrauch als einstöckig zu benutzen ist, bestehend aus der Patrone (1) und dem Gehäuse mit dem eigentlichen Öffnungsmechanismus (2), welche fest miteinander verbunden sind. Auch hier sind die Profilierung (3) für die Befestigung an das Aufnahmeteil der Weste zuerkennen und die Betätigungsleine mit dem Griffring (4). 4 shows the opening system, which in use is to be used as a single storey, consisting of the cartridge ( 1 ) and the housing with the actual opening mechanism ( 2 ), which are firmly connected. Here too, the profiling ( 3 ) for attachment to the receiving part of the vest and the operating line with the grip ring ( 4 ).

5 zeigt einen Vollschnitt durch das Öffnungsteil (2) mit einem Teil der Patrone (1). 6 zeigt einen detaillierten Auschnitt der 5 mit dem Patronenhals (1) und dem Öffnungsteil. Die Patrone (1) hat ein Gewinde, mit der die Patrone in das Gehäuseteil (4) geschraubt und z. B. mit Gewindekleber fest gesichert wird. Die Patrone ist mit einem Membranstück aus Metall (2) nach dem Befüllen der Patrone verschlossen. Das geschieht durch Verschweissung (7). Die Membran ist im Zentrum (3) etwas dünner ausgeführt zum leichteren Durchstoßen des Öffnungsdorns (6). Diese Art der Membran ist Stand der Technik. Wie oben beschrieben, sind trotzdem noch mehr ca. 300 N Kraft notwendig. 5 shows a full section through the opening part ( 2 ) with part of the cartridge ( 1 ). 6 shows a detailed section of the 5 with the cartridge neck ( 1 ) and the opening part. The bullet ( 1 ) has a thread, with which the cartridge in the housing part ( 4 ) screwed and z. B. is firmly secured with thread adhesive. The cartridge is equipped with a metal membrane piece ( 2 ) sealed after filling the cartridge. This is done by welding ( 7 ). The membrane is in the center ( 3 ) a bit thinner for easier piercing of the opening mandrel ( 6 ). This type of membrane is state of the art. As described above, about 300 N force are still required.

Ein wesentlicher Bestandteil bei dieser Erfindung ist die vom Stand der Technik abweichende Ausführung der Membran. Die dünnere Wand der Membran ist extrem dünn auszuführen, nur wenige hundertstel Millimeter dick. Diese Membran würde sich bei Druckzunahme bei höheren Lagertemperaturen nach außen wölben und bersten. Um dies zu verhindern, liegt ein Teil des Gehäuses (5) dicht an der dünnen Membranstelle und verhindert das Auswölben und Bersten der Membran. Das Gehäuse (4) ist aus Kunststoff gefertigt. Versuche haben ergeben, dass auch bei hohen Drücken weit über 200 bar die Patrone gasdicht blieb, die Öffnungskräfte für den Öffnungsdorn zum Durchstechen des stützenden Kunststoffs (5) und der Membran aber nur 30 – 50 N betragen. Dies ermöglicht, ein einfaches Aufblassystem zu erzielen und diese Einheit auch als sog. Einwegprodukt zu verstehen. Durch die Reduzierung der notwendigen Öffnungskräfte um nahezu 80 – 90 % sind alle Komponenten entsprechend günstiger zu fertigen.An essential component of this invention is the design of the membrane which differs from the prior art. The thinner wall of the membrane is extremely thin, only a few hundredths of a millimeter thick. This membrane would bulge and burst if the pressure increased at higher storage temperatures. To prevent this, part of the housing ( 5 ) close to the thin membrane point and prevents the membrane from bulging and bursting. The housing ( 4 ) is made of plastic. Tests have shown that the cartridge remained gas-tight even at high pressures well over 200 bar, the opening forces for the opening mandrel for piercing the supporting plastic ( 5 ) and the membrane are only 30 - 50 N. This makes it possible to achieve a simple inflation system and to understand this unit as a so-called disposable product. By reducing the necessary opening forces by almost 80 - 90 %, all components are cheaper to manufacture.

In 5 ist ein solches System als manuell und automatisch wirkendes Ausführungsbeispiel dargestellt. Man erkennt die Patrone (1) und das Kunststoffgehäuse (2). Der Öffnungsdorn (8) ist aus Messing gefertigt, weil er nur einmal benutzt wird, und steckt in einem axial beweglichem Zentralstößel (7). Durch Schwenken des Hebels (14) um den Achsenstift (15) wird der Öffnundsdorn in die Patrone gedrückt. Das Gas kann durch die Öffnung (13), welche beim Befestigen der Einheit an das Aufnahmeteil mit der Öffnung des Aufnahmeteils in Deckung liegt, in die Weste strömen. Für die automatische Auslösung des Öffnungsmechanismus durch Wassereinwirkung ist eine Druckfeder (9) vorgesehen, die auf einen Rezeß (18) des Zentralstößels und auf Stege (16) des Adapterteils (19) wirkt. Ein wasserlösliches Sperrelement (10) – meistens ist dies gepresste Zellulose -, das einen weiteren Rezeß (11) an dem Zentralstößel umschließt und mehr als z. B. 60 N Sperrwiderstand im trockenen Zustand hat, verhindert die Expansion der Feder. Die Kraft des manuell zu bedienenden Handhebels (14) zerstört beim Betätigen das Sperrelement und verschiebt den Zentralstößel axial zum Öffnen der Patrone.In 5 such a system is shown as a manually and automatically acting embodiment. You can see the cartridge ( 1 ) and the plastic housing ( 2 ). The opening mandrel ( 8th ) is made of brass because it is used only once and is in an axially movable central plunger ( 7 ). By swiveling the lever ( 14 ) around the axis pin ( 15 ) the opening mandrel is pressed into the cartridge. The gas can pass through the opening ( 13 ) which, when the unit is fastened to the receiving part, coincides with the opening of the receiving part, flow into the vest. For the automatic triggering of the opening mechanism by the action of water, a compression spring ( 9 ) provided on a recessive ( 18 ) of the central tappet and on webs ( 16 ) of the adapter part ( 19 ) works. A water-soluble blocking element ( 10 ) - mostly this is pressed cellulose - which is another recess ( 11 ) encloses on the central tappet and more than z. B. 60 N blocking resistance in the dry state, prevents the expansion of the spring. The power of the manually operated hand lever ( 14 ) destroys the locking element when actuated and moves the central plunger axially to open the cartridge.

Damit während der Lagerzeit der Aufblaseinheit nicht unnötig der Federdruck auf das Sperrelement wirkt, ist ein Sicherungsstift (17) vorgesehen, der zwischen Feder und Rezeßkante (18) des Zentralstößels eingeschoben ist. Vor dem Einsetzen der Aufblaseinheit in das Aufnahmeteil der Weste muß zwangsläufig der Stift herausgezogen werden.A locking pin (so that the spring pressure does not unnecessarily act on the locking element during the storage period of the inflator) 17 ) provided between the spring and recess edge ( 18 ) of the central tappet is inserted. Before inserting the inflation unit into the receiving part of the vest, the pin must be pulled out.
