Abstract
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.
