Description

Die vorliegende Erfindung betrifft ein Feuerlöschgerät mit mindestens zwei Löschmittelkammern, die über einen gemeinsamen Austrittskanal mit einer Austrittsöffnung verbunden sind.The present invention relates to a fire extinguisher with at least two extinguishing agent chambers, which are connected via a common outlet channel with an outlet opening.

Ein gattungsgemäßes Feuerlöschgerät ist aus der britischen Patentschrift GB 356 383 bekannt. Bei diesem Feuerlöschgerät sind zwei oder mehr getrennte Löschmittelbehälter in einem gemeinsamen Gehäuse untergebracht und können über einen Drehmechanismus nacheinander geöffnet werden. Die Löschmittelbehälter münden in einen gemeinsamen Austrittskanal, der eine Austrittsöffnung aufweist. Der Drehmechanismus dieses Feuerlöschgeräts ist vergleichsweise aufwendig gestaltet. Wenn mehr als zwei Löschmittelbehälter gewünscht sind, müssen sie im Kreis angeordnet werden, damit sie mittels des Drehmechanismus geöffnet werden können. Dies schränkt die Gestaltungsfreiheit der Anordnung ein und macht das Feuerlöschgerät klobig und unhandlich.A generic fire extinguisher is from the British patent specification GB 356,383 known. In this fire extinguisher two or more separate extinguishing agent containers are housed in a common housing and can be opened in succession via a rotating mechanism. The extinguishing agent containers open into a common outlet channel, which has an outlet opening. The rotating mechanism of this fire extinguisher is designed comparatively expensive. If more than two extinguishing agent containers are desired, they must be arranged in a circle so that they can be opened by means of the rotating mechanism. This restricts the design freedom of the arrangement and makes the fire extinguisher clumsy and unwieldy.

Ein weiteres Feuerlöschgerät ist aus der deutschen Offenlegungsschrift DE 36 13 686 A1 bekannt. Hierbei ist lediglich ein Löschmittelbehälter vorgesehen, der durch Innenwände in mehrere Löschmittelkammern unterteilt ist. Ein stromabwärts von den Löschmittelkammern folgendes seitlich von den Löschmittelkammern liegendes Steigrohr als gemeinsamer Austrittskanal mündet über ein Austrittsventil in eine Austrittsöffnung. Bei diesem Feuerlöschgerät ist die Gestaltungsfreiheit zwar größer, aber für jede gewünschte Anordnung von Löschmittelkammern muss ein separater Löschmittelbehälter hergestellt werden.Another fire extinguisher is from the German patent application DE 36 13 686 A1 known. Here, only an extinguishing agent container is provided, which is divided by inner walls into a plurality of extinguishing agent chambers. A downstream of the extinguishing agent chambers following the side of the extinguishing agent chambers riser as a common outlet channel opens via an outlet valve in an outlet opening. With this fire extinguisher, although the design freedom is greater, but for any desired arrangement of extinguishing agent chambers, a separate extinguishing agent container must be made.

Aus der WO 2004/002576 A1 ist ein tragbares Feuerlöschgerät bekannt, bei welchem ein erster flaschenförmiger Behälter in einem Beutel oder Schlauch ein Löschmittel und um dieses ein Treibgas enthält. Ein zweiter Behälter ist nur mit Treibgas gefüllt. Die beiden Behälter sind lösbar an einem übergreifenden Gehäuse verbunden, in welchem Ventile, Kanäle und Düsen ausgebildet sind. Jedem der beiden Behälter ist ein eigenes Austrittsventil und stromabwärts des Ventils ein eigener Austrittskanal in dem übergreifenden Gehäuse zugeordnet, wobei beide Ventile über einen gemeinsamen Handhebel betätigbar sind und die separaten Austrittskanäle in eine Mischkammer mit einer Spritzdüse münden.From the WO 2004/002576 A1 a portable fire extinguisher is known in which a first bottle-shaped container in a bag or hose an extinguishing agent and this contains a propellant gas. A second container is filled only with propellant gas. The two containers are detachably connected to a cross-housing in which valves, channels and nozzles are formed. Each of the two containers is associated with its own outlet valve and downstream of the valve, a separate outlet channel in the overarching housing, wherein both valves are actuated via a common hand lever and the separate outlet channels open into a mixing chamber with a spray nozzle.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, ein Feuerlöschgerät der o. g. Art derart weiterzubilden, dass eine große Gestaltungsfreiheit bei der Anordnung der Löschmittelbehälter bei möglichst geringem Herstellungsaufwand möglich ist.The object of the present invention is therefore to provide a fire extinguisher o. To develop such a way that a great freedom of design in the arrangement of the extinguishing agent container is possible with the lowest possible production cost.

Die Lösung besteht in einem Feuerlöschgerät mit den Merkmalen des Patentanspruchs 1. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The solution consists in a fire extinguisher with the features of claim 1. Advantageous developments emerge from the dependent claims.

Die Gestaltung des erfindungsgemäßen Feuerlöschgeräts erlaubt es, eine beliebige Anzahl von Löschmittelbehältern in beliebigen Anordnungen miteinander zu kombinieren. Auch Löschmittelbehälter unterschiedlicher Größe und Formen können nebeneinander verwendet werden. Die Löschmittelbehälter können insbesondere einzeln hintereinander oder nebeneinander in quadratischen oder rechteckigen Anordnungen oder nebeneinander auf Lücke in rhombischen oder trapezförmigen Anordnungen positioniert werden. In jedem Fall münden die als kommunizierende Röhren ausgestalteten Löschmittelbehälter in den ihnen gemeinsamen Austrittskanal und können durch Betätigung des einzigen Austrittsventils entleert werden. Auf demselben Weg, d. h. über das dann geöffnete Austrittsventil und den Austrittskanal, können sie nach ihrer Entleerung auch wieder befüllt werden. Das erfindungsgemäße Feuerlöschgerät kann somit modular aus individuell kombinierbaren Löschmittelbehältern beliebiger Größe und Form zu einem Gerät mit beliebiger Geometrie aufgebaut werden. Es ist nicht notwendig, für jede gewünschte Geometrie ein eigenes Gehäuse herzustellen.The design of the fire extinguishing device according to the invention makes it possible to combine any number of extinguishing agent containers in any arrangement with each other. Even extinguishing agent containers of different sizes and shapes can be used side by side. In particular, the extinguishing agent containers can be positioned one behind the other or side by side in square or rectangular arrangements or next to each other on a gap in rhombic or trapezoidal arrangements. In any case, designed as communicating tubes extinguishing agent tank open into their common outlet channel and can be emptied by pressing the single outlet valve. On the same way, d. H. via the then opened outlet valve and the outlet channel, they can also be refilled after their emptying. The fire extinguisher according to the invention can thus be modularly constructed from individually combinable extinguishing agent containers of any size and shape to a device with any geometry. It is not necessary to make your own housing for every desired geometry.

Das erfindungsgemäße Feuerlöschgerät kann insbesondere als tragbares Feurelöschgerät für Kraftfahrzeuge verwendet werden. Die Gestaltungsfreiheit bei der Auswahl und Anordnung der Löschmittelbehälter erlaubt es, für jede Kraftfahrzeuggröße geeignete, kompakte und flache Feuerlöschgeräte bereitzustellen, die beispielsweise unter dem Fahrer- oder Beifahrersitz untergebracht werden können und dennoch über ein ausreichendes Füllvolumen verfügen.The fire extinguisher according to the invention can be used in particular as a portable fire extinguisher for motor vehicles. The freedom of design in the selection and arrangement of the extinguishing agent container makes it possible to provide suitable, compact and flat fire extinguishers for each vehicle size, which can be accommodated, for example, under the driver or passenger seat and still have a sufficient filling volume.

Das Austrittsventil ist zweckmäßigerweise stromabwärts von den Löschmittelbehältern im Austrittskanal im Bereich der Austrittsöffnung angeordnet. Die Anordnung im Bereich der Austrittsöffnung vereinfacht das Auslösen des Ventils im Gebrauchsfall. Ein geeignetes Ventil ist beispielsweise ein federbelastetes Kegelsitzventil. Um die Bedienung des erfindungsgemäßen Feuerlöschgeräts weiter zu vereinfachen, kann das Austrittsventil beispielsweise mittels eines Hebels auslösbar sein, der vorzugsweise aus einer Nichtgebrauchslage in eine Gebrauchslage verschwenkbar ist.The outlet valve is expediently arranged downstream of the extinguishing agent containers in the outlet channel in the region of the outlet opening. The arrangement in the region of the outlet opening simplifies the triggering of the valve in use. A suitable valve is, for example, a spring-loaded cone seat valve. In order to further simplify the operation of the fire extinguishing device according to the invention, the outlet valve can be triggered for example by means of a lever, which is preferably pivotable from a non-use position into a position of use.

Jedem Löschmittelbehälter ist ein Steigrohr zugeordnet, welches mit dem Austrittskanal verbunden ist. Dies bewirkt eine dosierte Zuführung des Löschmittels in den Austrittskanal. Die Halterung eines Steigrohres kann sowohl in einer Wand des Austrittskanals als auch im Löschmittelbehälter selbst, beispielsweise mittels eines oder mehrerer im Löschmittelbehälter angebrachter Stege vorgenommen sein.Each extinguishing agent tank is associated with a riser, which is connected to the outlet channel. This causes a metered supply of the extinguishing agent in the outlet channel. The holder of a riser pipe can be made both in a wall of the outlet channel and in the extinguishing agent container itself, for example by means of one or more webs mounted in the extinguishing agent container.

Die Löschmittelbehälter sind vorzugsweise lose nebeneinander angeordnet, um die Herstellung des erfindungsgemäßen Löschmittelbehälters weiter zu vereinfachen.The extinguishing agent containers are preferably arranged loosely next to one another in order to further simplify the production of the extinguishing agent container according to the invention.

Der Austrittskanal ist in einem die Löschmittelbehälter übergreifenden Gehäuse angeordnet. Zweckmäßigerweise kann das Austrittsventil dann im Gehäuse angeordnet sein. Das hat den Vorteil, dass sämtliche Löschmittelbehälter auf einfache Weise mit dem Austrittskanal verbunden werden können. Die Ausgestaltung des erfindungsgemäßen Feuerlöschgeräts mit einem Gehäuse erlaubt es ferner, einen separaten Befüllkanal für Löschmittel vorzusehen, wobei jeder Löschmittelbehälter mit einer Füllöffnung versehen ist, welche in den Befüllkanal mündet. Damit sind die Kanäle für das Löschmittel beim Entleeren und beim Befüllen räumlich voneinander getrennt, was das Befüllen vereinfacht. In diesem Fall ist es auch zweckmäßig, dass jeder Löschmittelbehälter einen die Füllöffnung bildenden Stutzen aufweist, welcher in einer Wand des Befüllkanals gehalten ist. Der Stutzen kann beispielsweise in die Wand des Befüllkanals geschraubt oder gepresst sein. Ferner ist es sinnvoll, im Befüllkanal ein den Löschmittelbehältern stromaufwärts vorgeschaltetes Befüllventil, beispielsweise in Form eines Drehventils, vorzusehen.The outlet channel is arranged in a housing which covers the extinguishing agent container. Conveniently, the outlet valve can then be arranged in the housing. This has the advantage that all extinguishing agent container can be easily connected to the outlet channel. The design of the fire extinguishing device according to the invention with a housing further allows to provide a separate filling channel for extinguishing agent, each extinguishing agent container is provided with a filling opening, which opens into the filling channel. Thus, the channels for the extinguishing agent during emptying and filling are spatially separated, which simplifies the filling. In this case, it is also expedient that each extinguishing agent container has a connecting piece forming the filling opening, which is held in a wall of the filling channel. The nozzle may for example be screwed or pressed into the wall of the filling channel. Furthermore, it is useful to provide a filling valve upstream of the extinguishing agent containers upstream filling valve, for example in the form of a rotary valve.

Jedes Steigrohr kann in eine in einer Wand des Austrittskanals eingeformte Durchgangsöffnung münden und auf diese Weise mit dem Austrittskanal verbunden sein Dies bewirkt einen guten Sitz und eine definierte Sitztiefe der Steigrohre im Gehäuse. Ferner wird die Montage der Steigrohre im Gehäuse vereinfachtEach riser can open into a through opening formed in a wall of the outlet channel and in this way be connected to the outlet channel. This causes a good fit and a defined seat depth of the riser tubes in the housing. Furthermore, the mounting of the riser pipes in the housing is simplified

Die Austrittsöffnung kann auch als vom Austrittskanal räumlich getrenntes Austrittsrohr ausgebildet sein, um das Gehäuse zu durchdringen, insbesondere wenn das Austrittsventil mittig zwischen den Steigrohren angeordnet ist. Dann empfiehlt es sich, das Austrittsventil zwischen dem Austrittskanal und dem Austrittsrohr anzuordnen.The outlet opening may also be formed as an outlet tube spatially separated from the outlet tube to penetrate the housing, in particular when the outlet valve is arranged centrally between the riser tubes. Then it is recommended to arrange the outlet valve between the outlet channel and the outlet pipe.

Für die Verwendung als tragbares Feuerlöschgerät in PKWs hat es sich als zweckmäßig erwiesen, drei Löschmittelbehälter vorzusehen.For use as a portable fire extinguisher in passenger cars, it has proven expedient to provide three extinguishing agent containers.
