Description

Die Erfindung betrifft eine automatische Aufblasvorrichtung für eine Taucher-Rettungsweste.The invention relates to an automatic inflator for a diving life jacket.

An das Tauchgerät-Reduzierventil angeschlossene Auf- blassysteme für eine Rettungsweste sind bekannt und in der Praxis verbreitet. Die Betätigung erfolgt manuell. Die Weste dient entweder zum Tarrieren des Tauchers und karn in einer Notsituation zu vollem Aufblasen und schnellen Auftrauchen Verwendung finden. Das Aufblasen der Rettungweste wird durch manuelles Be tätigen eines auf den Mitteldruckausgang angeschlossenen Ventils durchgeführt. Das Entleeren der Rettungsweste erfolgt durch das Betätigen des auf den Westen-Faltenschlauch angeschlossenen Ventils.To the scuba reducing valve connected up b la ssysteme for a life jacket are widely known and in practice. It is operated manually. The vest is used either for taring the diver and can be used in an emergency situation for full inflation and quick exhaustion. The life jacket is inflated by manually actuating a valve connected to the medium pressure outlet. The life jacket is emptied by actuating the valve connected to the vest corrugated hose.

In einer Notsituation, wo der Taucher handlungsunfähig und zuletzt bewusstlos ist, nützt ihm die manuelle Betätigung nichts. Die Hilfe kommt bei solchen Unfällen meist zu spät.In an emergency situation where the diver is unable to act and is ultimately passed out, manual operation is of no use to him. Help is usually too late in such accidents.

Der Erfindung liegt die Aufgabe zugrunde, ein Ventil für ein automatisches

der Rettungsweste zu schaffen, das bei stark verminderter oder aufgehörter Atemtätigkeit des Tauchers in Funktion tritt. Das Aufblasventil soll auch das manuelle Aufblasen und Leeren der Rettungsweste ermöglichen. Erfindungsgemäss wird dies dadurch erreicht, dass ein Zeitverzögerungselement, das mit einem Atmungsfühler in Wirkverbindung steht, dessen beweglicher Teil (5,6) sich beim Ausbleiben der Atmung entgegen der Bremswirkung des Zeitverzögerungselementes verschiebt und dabei ein Aufblasventil (15) öffnet. Das Zeitverzögerungselement kann nach dem hydraulischen oder mechanischen Prinzip arbeiten,.oder die laminare Reibung einer sehr viskoser Flüssigkeit ausnützen. Dass das Auplasventil an der Luft blockiert ist, kann durch manuelle oder automatische Arretierung erreicht werden.The invention has for its object a valve for an automatic

Der BetriebThe operation

Im drucklosen Zustand befindet sich die Anschlagsplatte 5 links am Anschlag des Deckels 8. Vor dem Tauchbeginn wird der nicht dargestellte Lungenautomat eingeschaltet und Druckluft strömt durch den Druckschlauch 22 und durch den Spalt zwischen der Membrane 9 und der Anschlagsplatte 5 in den Raum 33 der automatischen Aufblasvorrichtung. Durch den Druckunterschied zwischen dem Raum 33 und Aussen bewegt sich die Stange 6 des Atmungsfühlers langsam nach rechts, gebremst durch die Flüssigkeit 34, welche den Kolben 3 umströmen muss. Wenn aus dem Lungenautomaten nicht geatment wird, bewegt sich die Stange 6 so weiter nach rechts, bis der Kragen der Anschlagplatte 5 das Aufblasventil 15 öffnet. Jetzt strömt Druckluft durch den Ventilkörper 14 in das Ventilgehäuse 4 und von dort durch den Faltenschlauch 41 in die Rettungsweste. Damit die Rettungsweste nur unter Wasser und nicht beim Schnorcheln oder bereits vor dem Eintauchen automatisch aufgeblasen wird, ist rechts im Zylinder 2 eine auf Aussendruck abhängige Arretierung, bestehend aus einer Zellkautschukscheibe 12, eingebaut. Diese wird durch den Wasserdruck in einer Tiefe von 2 bis 3 m so weit zusammengedrückt, dass sie das rechte Ende der Stange 6 nicht mehr berührt, so dass die Anschlagsplatte 5 das Aufblasventil 15 öffnen kann. Wenn der Taucher normal atmet, entstehen im Niederdruckbereich des Lungenautomaten Drucksenkungen. Diese werden durch den Druckschlauch 22 in das Gehäuse 1 weitergeleitet. Bei jeder Drucksenkung wird die Membrane 9 an die Anschlagsplatte 5 wie ein Rückschlagsventil spiellos eingedrückt, so dass die beiden Teile eine Einheit bilden. Die Drucksenkung wird dann die Bewegung der Anschlagsplatte 5 und Stange 6 durch elastisches Ausdehnen des im Verbindungsrohr 7 jetzt dicht eingeschlossenen Luftvolumens 33 bewirken. Diese Bewegung wird bei jedem Einatmen die Stange 6 mit Anschlagsplatte 5 nach links befördern und verunmöglicht das Oeffnen des Aufblasventils 15, während des normalen Tauchgangs. Die Membrane 9 lässt beim Druckanstieg, z.B. beim Abtauchen oder wenn das Aufblasventil 15 offen ist, Luft in den Raum 33 eintreten. Der Taucher kann auch nach eigenem Ermessen die Rettungsweste aufblasen durch das Drücken auf den Knonf 13,In the depressurized state, the stop plate 5 is on the left at the stop of the lid 8. Before the start of diving, the lung regulator (not shown) is switched on and compressed air flows through the pressure hose 22 and through the gap between the membrane 9 and the stop plate 5 into the space 33 of the automatic inflator . Due to the pressure difference between the space 33 and the outside, the rod 6 of the breathing sensor slowly moves to the right, braked by the liquid 34, which has to flow around the piston 3. If there is no breathing from the regulator, the rod 6 continues to the right until the collar of the stop plate 5 opens the inflation valve 15. Compressed air now flows through the valve body 14 into the valve housing 4 and from there through the corrugated hose 41 into the life jacket. So that the life jacket rchel s only water and not the Schno or automatically inflated before the immersion, is right in the cylinder 2 a lock dependent on external pressure, consisting of a cellular rubber disk 12, installed. This is compressed to a depth of 2 to 3 m by the water pressure so that it no longer touches the right end of the rod 6, so that the stop plate 5 can open the inflation valve 15. If the diver breathes normally, pressure drops occur in the low pressure area of the regulator. These are passed through the pressure hose 22 into the housing 1. Each time the pressure drops, the membrane 9 is pressed onto the stop plate 5 like a check valve without play, so that the two parts form a unit. The reduction in pressure will then cause the movement of the stop plate 5 and rod 6 by elastic expansion of the air volume 33 now sealed in the connecting tube 7. This movement will move the rod 6 with the stop plate 5 to the left with each inhalation and make it impossible to open the inflation valve 15 during the normal dive. The membrane 9 leaves when the pressure rises, for example when Submerge or when the inflation valve 15 is open, air into the room 33. The diver can also inflate the life jacket at his own discretion by pressing button 13,

Luft auslassen durch das Drücken auf den Knopf 20 oder notatmen durch das Mundstück 30.Release air by pressing button 20 or breathe through mouthpiece 30.

Die automatische Aufblasvorrichtung für die Taucher-Rettungsweste gibt dem Taucher zusätzliche Sicherheit gegen Taucherunfälle. Die Ausrüstung ist einfach, verlangt keine spezielle Bedienung und ist in die zurzeit übliche Taucher-Rettungsweste so integriert, dass der Taucher bei der Handhabung seine bisherigen Gewohnheiten beibehalten kann.The automatic inflator for the diving life jacket gives the diver additional security against diving accidents.
