Description

Die Erfindung betrifft einen Feuerlöscher mit einem Behälter für die Aufnahme von Löschmitteln wie, Löschpulver, Wasser, Wasser-Schaummittel-Gemisch, Halon oder dergleichen, mit ei­nem Behältervolumen zwischen 1 und 15 Ltr. und einem auf das Löschmittel wirkenden Arbeitsdruck von 5 bis 25 bar, sowie ei­nem Ventil zum Austragen des Löschmittels.The invention relates to a fire extinguisher with a container for holding extinguishing agents such as, extinguishing powder, water, water-foam mixture, halon or the like, with a container volume between 1 and 15 liters and a working pressure on the extinguishing agent of 5 to 25 bar , and a valve to discharge the extinguishing agent.

Derartige Feuerlöscher werden als mobile oder halb-stationäre Löscher eingesetzt, wobei die Behälter aus Stahl- oder Alumini­umblech gefertigt sind.Fire extinguishers of this type are used as mobile or semi-stationary extinguishers, the containers being made from sheet steel or aluminum.

Der Erfindung liegt die Aufgabe zugrunde einen Behälter für Feu­erlöscher zu schaffen, der besser handhabbar ist, korrosions­beständig ist und gleichzeitig preiswerter hergestellt werden kann.The invention has for its object to provide a container for fire extinguishers that is easier to handle, is corrosion-resistant and at the same time can be manufactured cheaper.

Diese Aufgabe wird dadurch gelöst, daß der Behälter aus einem Kunststoff besteht und der Behältermantel nach dem sogenannten Streckblasverfahren aus einem Formling hergestellt ist. Dabei kann der aus PETP, Polyacrylnitril oder dergleichen bestehende Formling gespritzt sein.This object is achieved in that the container consists of a plastic and the container jacket is made from a molded article according to the so-called stretch blow molding process. The molding made of PETP, polyacrylonitrile or the like can be injection molded.

Der gespritzte, hohlkörperartige Formling ist an einem Ende ge­schlossen und am anderen Ende mit einem Behälterhals versehen. Dieser wird in eine Blasmaschine eingespannt und der restliche Teil des Formlings in eine Form geblasen, wodurch der Behälter­ mantel entsteht. Bei dieser Verfahrensweise streckt sich das Ma­terial, vorzugsweise im Verhältnis von 1 : 6 bis 1 : 12 und ver­festigt sich gleichzeitig. Diese Verfestigung erlaubt es, den Kunststoffbehälter als Feuerlöscher mit einem auf das Löschmittel wirkenden, hohen Arbeitsdruck zu betreiben. Dieser hohe Arbeits­druck ist erforderlich, um das Löschmittel im Brandfalle schnell und sicher aus dem Behälter auszutreiben. Bisher war man der Mei­nung, Feuerlöscher aus Kunststoff seien für den geforderten Druck- und Temperaturbereich nicht wirtschaftlich herstellbar.The injection molded, hollow body-like molding is closed at one end and provided with a container neck at the other end. This is clamped in a blow molding machine and the remaining part of the molded part is blown into a mold, creating the container coat arises. In this procedure, the material stretches, preferably in a ratio of 1: 6 to 1:12, and solidifies at the same time. This solidification allows the plastic container to be operated as a fire extinguisher with a high working pressure acting on the extinguishing agent. This high working pressure is required to quickly and safely drive the extinguishing agent out of the container in the event of a fire. Until now, it was believed that plastic fire extinguishers could not be manufactured economically for the required pressure and temperature range.

Ein erfindungsgemäßer Feuerlöscher aus Kunststoff hat gegenüber den metallenen Feuerlöscher den Vorteil, daß er leichter und somit besser handhabbar ist. Dies ist insbesondere bei mobilen Handlöschern von Vorteil. Fernerhin ist der aus Kunststoff be­stehende Löscher länger haltbar, weil er korrosionsbeständiger ist als die bisherigen metallenen Löscher. Ein weiterer Vorteil des erfindungsgemäßen Löschers ist darin zu sehen, daß seine Her­stellungskosten gegenüber den bisherigen Löschern deutlich ge­ringer sind. Dieser Preisvorteil gestattet unter Umständen den Einsatz als Einweglöschern. Dies bedeutet, daß anstelle der ge­setzlich vorgeschriebenen Inspektionen, Füllkontrollen und Nach­füllungen ein Austausch tritt.A plastic fire extinguisher according to the invention has the advantage over the metal fire extinguisher that it is lighter and therefore easier to handle. This is particularly advantageous for mobile hand-held extinguishers. Furthermore, the extinguisher made of plastic has a longer shelf life because it is more corrosion-resistant than the previous metal extinguishers. Another advantage of the extinguisher according to the invention can be seen in the fact that its production costs are significantly lower compared to the previous extinguishers. This price advantage may permit use as a disposable extinguisher. This means that an exchange takes place instead of the statutory inspections, filling controls and refills.

Der erfindungsgemäße Feuerlöscher-Behälter hat noch einen opti­schen Vorteil. Der Behältermantel kann ohne Schwierigkeiten mit einfachsten Mitteln in jede beliebige Form gebracht werden. Da­mit kann der Behälter eine für den Anmelder typische Form auf­weisen, die wie ein Geschmacksmuster wirkt und folglich werbe­wirksam ist. Die hohen Herstellungskosten bei den metallenen Feuerlöscher-Behältern ließen eine typische Formgebung nur be­dingt zu.The fire extinguisher container according to the invention also has an optical advantage. The container jacket can be used without difficulty simplest means can be brought into any shape. The container can thus have a shape which is typical for the applicant and which acts like a design and is consequently effective in advertising. The high manufacturing costs of the metal fire extinguisher containers only allowed a typical shape to a limited extent.

Mittels des Streckblasverfahrens kann ein Formling verwendet werden, an den ein Stutzen mit Gewinde angebracht ist, so daß ein Kunststoffventil aufgesetzt werden kann und damit der ge­samte Feuerlöscher aus Kunststoff besteht, mit all den vor­stehend genannten Vorteilen.By means of the stretch blow molding process, a molded article can be used, to which a threaded connection piece is attached, so that a plastic valve can be attached and the entire fire extinguisher is made of plastic, with all the advantages mentioned above.

Bei vielen metallenen Behältern ist der untere Teil als Ku­gelboden ausgebildet und zur Standsicherheit des Feuerlöschers mit einem Bodenteil versehen. Aufgrund der erfindungsgemäßen Maßnahme kann der Behältermantel und der Behälter-Standboden aus einem Teil gespritzt werden. Auch hierdurch verringern sich die Herstell- und Montagekosten.In many metal containers, the lower part is designed as a spherical base and is provided with a base part to ensure the fire extinguisher's stability. Because of the measure according to the invention, the container jacket and the container base can be injection molded from one part. This also reduces the manufacturing and assembly costs.

Das Streckblasverfahren erlaubt, Teile des Behältermantels trans­parent herzustellen. Damit kann mit einfachsten Mitteln eine Füllkontrolle für das Löschmittel geschaffen werden.The stretch blow molding process allows parts of the container casing to be made transparent. A filling control for the extinguishing agent can thus be created with the simplest means.

Feuerlöscher werden als Aufladedrucklöscher oder als Dauerdruck­löscher verwendet. Im letzteren Falle wird das Feuerlöschmittel mit einem unter Druck stehenden Gas überlagert, das bei Öffnen des Löschventiles das Löschmittel austreibt.Fire extinguishers are used as boost pressure extinguishers or as permanent pressure extinguishers. In the latter case, the fire extinguishing agent is overlaid with a gas under pressure, which expels the extinguishing agent when the extinguishing valve is opened.

Damit steht der Löscher ständig unter Druck. Im ersteren Falle ist eine zusätzliche Druckgasquelle vorgesehen, die innerhalb oder außerhalb des Behälters angebracht ist und nur im Brandfal­le den Behälter unter Druck setzt und damit das Löschmittel aus­treibt. Der Aufladedruck-Feuerlöscher hat den Vorteil, daß durch eine etwa vorhandene Permeabilität kein Druckverlust entsteht.This puts the extinguisher under constant pressure. In the former case, an additional source of pressurized gas is provided, which is attached inside or outside the container and only pressurizes the container in the event of fire and thus expels the extinguishing agent. The boost pressure fire extinguisher has the advantage that there is no pressure loss due to an existing permeability.

Ein Ausführungsbeispiel der Erfindung ist anhand eines Auflade­druck-Feuerlöschers mit innenliegender Druckquelle dargestellt und wird nachfolgend näher beschrieben.An embodiment of the invention is shown using a supercharger fire extinguisher with an internal pressure source and is described in more detail below.

Der Feuerlöscher 1 besteht aus einem Behälter 2 und einem Ven­til 3. Der Behälter 2 ist aus einem nicht dargestellten Form­ling im Streckblasverfahren hergestellt. Der Formling besitzt einen Behälterhals 4 auf den ein Gewindestutzen 5 aufgespritzt ist. Der Behälterhals 4 wird in die nicht dargestellte Streck­blasmaschine eingespannt und damit der Behältermantel 6 im Streckblasverfahren hergestellt, wobei die Dicke des Behälter­mantels 6 gegenüber der ursprünglichen Dicke des Formlings we­sentlich dünner ist. Durch den Streckvorgang wird die Festigkeit des Behältermantels 6 soweit verstärkt, daß der für einen ord­nungsgemäßen Betrieb erforderliche Arbeitsdruck vom Behältermantel 6 aufgenommen werden kann. Im Ausführungsbeispiel ist der Behäl­terboden gleichzeitig mit dem Behältermantel 6 im Streckblasver­fahren hergestellt. Folglich bestehen die Teile 6 und 7 aus einem Stück. Das Ventil 3 hat vorzugsweise einen Ventilstutzen 8 mit Innengewinde 6, das auf das Außengewinde des Stutzens 5 auf­schraubbar ist. Mit einem Ventilhebel 9 kann ein Ventilstößel 12 betätigt werden, der eine Druckflasche 11 öffnet und das inner­halb des Behältermantels 6 befindliche Löschmittel über die Aus­trittsdüse 10 austreibt. Ein Ventileinsatz 14 ist mit dem Ven­tilstutzen 8 verbunden und führt einerseits den Ventilstößel 12 und andererseits trägt er die Druckflasche 11 und ein Steigrohr 13.The fire extinguisher 1 consists of a container 2 and a valve 3. The container 2 is made from a blank, not shown, in the stretch blow molding process. The molding has a container neck 4 onto which a threaded connector 5 is sprayed. The container neck 4 is clamped in the stretch blow molding machine, not shown, and thus the container jacket 6 is produced in the stretch blow molding process, the thickness of the container jacket 6 being considerably thinner than the original thickness of the molding. The strengthening of the container casing 6 is increased by the stretching process to such an extent that the working pressure required for proper operation can be absorbed by the container casing 6. In the exemplary embodiment, the container bottom is produced simultaneously with the container jacket 6 in the stretch blow molding process. Consequently, parts 6 and 7 are made in one piece. The valve 3 preferably has a valve socket 8 with Internal thread 6, which can be screwed onto the external thread of the connector 5. A valve tappet 12 can be actuated with a valve lever 9, which opens a pressure bottle 11 and drives out the extinguishing agent located within the container jacket 6 via the outlet nozzle 10. A valve insert 14 is connected to the valve stub 8 and on the one hand guides the valve tappet 12 and on the other hand it carries the pressure bottle 11 and a riser pipe 13.
