Außerdem soll das Gerät schnell, einfach und ohne Spezialkenntnisse befüllbar und wiederbefüllbar sein.The object of the invention is to provide a portable fire extinguisher that is so small and light that it can be carried as a piece of equipment by users in use constantly without burdening the wearer in addition to his other device excessively, but on the other hand is sufficient to to be able to extinguish a burning person safely. In addition, the device should be fast, easy and without special knowledge to be filled and refillable.

Diese Aufgabe wird gemäß der Erfindung durch das im Anspruch 1 angegebene Feuerlöschgerät gelöst.This object is achieved according to the invention by the fire extinguishing device specified in claim 1.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments and modifications of the invention are the subject of the dependent claims.

Ein Ausführungsbeispiel der Erfindung ist in der anliegenden schematischen Zeichnung dargestellt und wird nachstehend mehr im Einzelnen beschrieben.An embodiment of the invention is illustrated in the attached schematic drawing and will be described in more detail below.

Die Zeichnung zeigt ein Feuerlöschgerät nach der Erfindung in schematischer, teilweise aufgebrochener Seitenansicht und auseinandergezogener Darstellung von Löschmittelbehälter und Behälteraufsatz.The drawing shows a fire extinguisher according to the invention in a schematic, partially broken side view and exploded view of extinguishing agent container and container attachment.

Das Feuerlöschgerät weist einen druckfesten Löschmittelbehälter 1 in Gestalt einer Stahlflasche auf. Oben ist der Löschmittelbehälter 1 mit einem verjüngten Hals ausgebildet, der die Behälteröffnung umschließt und mit einem inneren Schraubgewinde versehen ist.The fire extinguisher has a pressure-resistant extinguishing agent container 1 in the form of a steel bottle. Above the extinguishing agent container 1 is formed with a tapered neck which encloses the container opening and is provided with an internal screw thread.

Weiter weist das Feuerlöschgerät einen Behälteraufsatz 3 in Gestalt einer integralen Baugruppe auf, die zugleich den Löschmittelbehälter 1 verschließt.Next, the fire extinguisher on a container attachment 3 in the form of an integral assembly, which closes the extinguishing agent container 1 at the same time.

Der Behälteraufsatz besteht seinerseits aus einer Löschpistole 4 mit einem Griffstück 5, einer Pistolendüse 6, einem Betätigungshebel 7 und einem Schutzbügel 8. Die Löschpistole 4 ist auf einem Armaturenblock 9 montiert, der unten einen mit Außengewinden versehenen Einschraubstutzen 10 aufweist, der in das Innengewinde des Halses 2 des Löschmittelbehälter 1 einschraubbar ist.The container attachment consists in turn of an extinguishing pistol 4 with a handle 5, a gun nozzle 6, an actuating lever 7 and a protective bracket 8. The extinguishing pistol 4 is mounted on a dashboard 9, which has an externally threaded mounting boss 10 below, in the internal thread of the Halses 2 of the extinguishing agent container 1 is screwed.

Der Besseren Erkennbarkeit halber ist in der Zeichnung der Löschmittelbehälter 1und der Behälteraufsatz 3 in leicht auseinandergezogener Darstellung gezeigt, wobei der obere Endbereich des Löschmittelbehälters im Schnitt dargestellt ist.For the sake of clarity, the extinguishing agent container 1 and the container attachment 3 are shown in a slightly exploded view in the drawing, with the upper end region of the extinguishing agent container being shown in section.

Von dem Einschraubstutzen 10 ragt ein Tauchrohr 11 nach unten, das, wenn der Behälteraufsatz 3 auf den Löschmittelbehälter 1 aufgeschraubt ist, kurz vor dem Boden des Löschmittelbehälters endigt. Das Innere des Tauchrohrs 11 setzt sich im Armaturenblock 9 und im Griffstück 4 fort in einem Kanal 12, der an geeigneter Stelle, in der Zeichnung nur schematisch dargestellt, ein Absperrventil 13 enthält, das in seiner Schließstellung vorgespannt und durch den Handhebel 7 im Sinne der Ventilöffnung betätigbar ist.From the mounting boss 10, a dip tube 11 projects downwards, which, when the container attachment 3 is screwed onto the extinguishing agent container 1, terminates shortly before the bottom of the extinguishing agent container. The interior of the dip tube 11 continues in the armature block 9 and in the handle 4 in a channel 12 which at a suitable location, shown only schematically in the drawing, a check valve 13 which is biased in its closed position and by the hand lever 7 in the sense of Valve opening is actuated.

Weiter weist der Armaturenblock 9 einen Druckgaseinlassstutzen 14 auf, der (nicht dargestellt) mit einem Schnellkupplungsmechanismus zum Aufstecken eines Druckgasfüllschlauchs ausgebildet ist, und der sich im Armaturenblock und im Einschraubstutzen 10 in einem Kanal 15 fortsetzt, der unten am Einschraubstutzen in das Innere des Löschmittelbehälters 1 ausmündet und im Armaturenblock 9 ein Rückschlagventil 16 enthält.Next, the valve block 9 a Druckgaseinlassstutzen 14, which is formed (not shown) with a quick coupling mechanism for attaching a Druckgasfüllschlauchs, and continues in the dashboard and in the screw 10 in a channel 15, the bottom of the screw into the interior of the extinguishing agent container. 1 opens and contains a check valve 16 in the dashboard 9.

Zum Füllen des Feuerlöschers wird der Behälteraufsatz 3 von dem Löschmittelbehälter 1 heruntergeschraubt, und dann wird durch den Hals 2 des Löschmittelbehälters 1, gegebenenfalls mit Hilfe eines Trichters, Wasser und etwas Schaummittel eingesetzt, bis ein Füllpegel 17 erreicht ist, der einen Füllstand von etwa 2/3 des Behältervolumens entspricht, so dass über der Flüssigkeitsfüllung ein ausreichend großer Gasraum zur Aufnahme von Druckgas verbleibt. Nach dem Einfüllen von Wasser und Schaummittel wird der Behälteraufsatz 3 auf den Löschmittelbehälter 1 aufgeschraubt. Es versteht sich, dass eine - in der Zeichnung aus Vereinfachungsgründen - nicht dargestellte druckfeste Dichtung vorgesehen ist, die zwischen dem Hals 2 des Löschmittelbehälters und dem Einschraubstutzen 10 bzw. der Unterseite des Armaturenblocks 9 wirksam ist. Die Anordnung ist dabei so getroffen, dass unter Zuhilfenahme des Griffstücks 4 der Behälteraufsatz 3 ohne Benutzung eines Werkzeugs auf den Löschmittelbehälter 1 aufschraubbar ist und auch das Abschrauben des Behälteraufsatzes 3 wieder ohne Werkzeug erfolgen kann. Nach dem Aufschrauben des Behälteraufsatzes 3 auf den mit Wasser und Schaummittelzusatz gefüllten Löschmittelbehälter 1 erfolgt das Befüllen das Druckgas, in dem auf den Gaseinfüllstutzen 14 ein Druckgasschlauch aufgesteckt wird, der mit einer Druckgasflasche oder einer anderen Druckgasquelle über Druckminderer verbunden ist, und der Gasraum über der Flüssigkeitsfüllung kann dann über das Rückschlagventil 16 mit Druckgas befüllt werden, beispielsweise mit Druckluft, bis der vorgesehene Druck erreicht ist.To fill the fire extinguisher, the container attachment 3 is screwed down from the extinguishing agent container 1, and then water and some foaming agent is used through the neck 2 of the extinguishing agent container 1, if necessary with the aid of a funnel, until a filling level of about 2 is reached / 3 of the container volume corresponds, so that above the liquid filling a sufficiently large gas space for receiving pressurized gas remains. After filling with water and foaming agent, the container attachment 3 is screwed onto the extinguishing agent container 1. It is understood that a - not shown pressure-resistant seal is provided in the drawing for reasons of simplification, which is effective between the neck 2 of the extinguishing agent container and the mounting boss 10 and the underside of the valve block 9. The arrangement is made such that with the aid of the handle 4 of the container attachment 3 can be screwed onto the extinguishing agent container 1 without the use of a tool and also the unscrewing of the container attachment 3 can be done again without tools. After screwing the container attachment 3 on the filled with water and foam additive extinguishing agent tank 1, the filling takes place, the compressed gas, in which a gas hose 14 is attached to the compressed gas hose, which is connected to a compressed gas cylinder or other source of pressurized gas via pressure reducer, and the gas space above the Liquid filling can then be filled via the check valve 16 with compressed gas, for example, with compressed air until the intended pressure is reached.

Das Löschgerät ist dann betriebsbereit. Bei Betätigung des Handhebels 7 wird das Absperrventil 13 geöffnet und Wasser/Schaummittelgemisch durch das Tauchrohr 11, den Kanal 12 und die Düse 6 herausgedrückt, welches die Düse 6 als Schaumsprühstrahl verlässt und mit einer Wurfweite von ca. 7 Meter auf eine brennende Person gerichtet werden kann.The extinguisher is then ready for use. Upon actuation of the hand lever 7, the shut-off valve 13 is opened and pushed water / foam mixture through the dip tube 11, the channel 12 and the nozzle 6, which leaves the nozzle 6 as a foam spray and are directed with a throw of about 7 meters to a burning person can.

Typischerweise hat der Löschmittelbehälter 1 ein Füllvolumen von insgesamt etwa 2,25 Liter; die Flüssigkeitsfüllung besteht aus ca. 1,5 Liter Wasser/Schaumzusatz im Mischungsverhältnis von 98% Wasser und 2% Schaumzusatz, also 1,47 Liter Wasser und 0,03 Liter Schaumzusatz; das Druckgasvolumen beträgt dann etwa 0,75 Liter und der Druckgasfülldruck 15 bar. Das betriebsfertige, gefüllte Löschgerät hat dann ein Gesamtgewicht von maximal 3,0 Kg. Der Durchfluss des Löschmittels im Betrieb kann etwa 10 Liter pro Minute betragen. Es ergibt sich dann bei dem genannten Betriebsdruck eine Wurfweite bis zu 7 Meter und eine minimale Funktionsdauer von ca. 9 Sekunden. Bei den genannten Füllmengen von Flüssigkeitsfüllung und Druckgasfüllung und dem genannten Betriebsdruck ergibt sich nach Verbrauch des Löschmittels noch ein Restdruck von ca. 5 bar.Typically, the extinguishant container 1 has a total fill volume of about 2.25 liters; the liquid filling consists of approx. 1.5 liters of water / foam additive in a mixing ratio of 98% water and 2% foam additive, ie 1.47 liters of water and 0.03 liters of foam additive; the compressed gas volume is then about 0.75 liters and the Druckgasfülldruck 15 bar. The ready-to-use, filled extinguisher then has a total weight of a maximum of 3.0 kg. The flow rate of the extinguishing agent during operation can be about 10 liters per minute. It then results in the said operating pressure a throw of up to 7 meters and a minimum duration of about 9 seconds. In the case of the aforementioned fill quantities of liquid filling and compressed gas filling and the said operating pressure, a residual pressure of approximately 5 bar still results after consumption of the extinguishing agent.

Das so ausgestaltete Gerät hat bei einer praktisch realisierten Ausführungsform einen Außendurchmesser des Löschmittelbehälters von 108 mm, eine Bauhöhe von insgesamt ca. 510 mm und ein betriebsfertiges Gesamtgewicht von maximal 3 Kg, kann also von einer Einsatzperson in einem Einsatz leicht mitgetragen werden, beispielsweise am Gürtel hängend, ohne dass die Person durch Gewicht oder Größe des Geräts wesentlich behindert wird.The device designed in this way has an outer diameter of the extinguishing agent container of 108 mm, a total height of about 510 mm and a ready-to-use total weight of 3 kg, so it can easily be carried by an operator in an insert, for example on the belt hanging, without the person being significantly impeded by the weight or size of the device.
