Tragbares, akustisches Warngerät Die Neuerung betrifft ein akustisches Warngerät. Portable, acoustic warning device The innovation concerns an acoustic warning device.
Die Neuerung erstrebt ein Warngerät einfacher Bauform zum Anschluß an eine Preßgasflasche.und insbesondere auch ein Warngerät,'dessen Tonhöhe unterschiedlich eingestellt werden kann. Durch die Neuerung ergibt sich der Vorteil eines einfachen Aufbaues. Das Membrangehäuse ist mit dem Druckminderer in einem Gehäuse untergebracht, der seinerseits über eine einfache Handverschraubung an eine Preßgasflasche angeschlossen werden kann.The innovation aims at a warning device of a simple design for connection to a compressed gas cylinder and, in particular, a Warning device, 'the pitch of which can be set differently. The innovation results in the advantage of a simple one Superstructure. The diaphragm housing is housed with the pressure reducer in a housing, which in turn has a simple hand screw connection can be connected to a compressed gas cylinder.
Gemäß einer weiteren Ausbildung kann das Gerät so ausgebildetAccording to a further embodiment, the device can be designed in this way
Rohrstutzen sein, daß der Signalhorntrichter gegenüber seinemPipe socket that the horn funnel opposite his
verschiebbar ist.is movable.
Weitere Einzelheiten der Neuerung sind Gegenstand der Unteransprüche und sind an Hand des in der Zeichnung schematisch dargestellten Ausführungsbeispiels erläutert, und zwar zeigtFurther details of the innovation are the subject of the subclaims and are explained with reference to the exemplary embodiment shown schematically in the drawing, namely shows
Abb. 1 den gesamten Aufbau eines Gerätes und Abb. 2 das Membrangehäuse, teilweise im Schnitt.Fig. 1 shows the entire structure of a device and Fig. 2 shows the membrane housing, partly in section.
Das Gerät besteht einmal aus einer Druckgasflasche 1 mit Piaschenventil 2 und einem Traggurt J, mit dem diese Bauteile beispielsweise auf dem Rücken des Gerätträgers getragen werden können.The device consists of a pressurized gas cylinder 1 with a Piaschenventil 2 and a strap J with which these components for example, can be carried on the back of the device wearer.
Zum anderen besteht das Gerät aus einem Signalhorn 4, das über ein Gehäuse 5 mit Hilfe der Handverschraubung 5a an das Flaschenventil 2 angeschlossen werden kann.On the other hand, the device consists of a horn 4, which over a housing 5 with the aid of the hand screw 5a on the bottle valve 2 can be connected.
An dem Gehäuse 5 ist auch noch der Druckmesser 6 angeschlossen.The pressure gauge 6 is also connected to the housing 5.

Der an das Si'seteffiSHäepeF^eHfeü 2 anschließbare Stutzen 7 ist
über die Gehäusebohrung 8 mit dem Druckminderer 9 verbunden,
durch den der Flasehendruck auf den notwendigen Betriebsdruck vermindert wird. Das entspannte Druckgas strömt über die
Dosierungsbohrung 10 in der Leitung 11 zur Druckfeiammer 12 oberhalb der Schallmembran 13* die ebenfalls im Gehäuse 5
angeordnet ist. Die Schallmembran liegt der Dichtkante 14
des Anschlußstutzens 15 für den Signalhorntrichter 17 an. Durch die in der Druckkammer 12 einströmende Luft wird dieBottle valve
The connector 7 that can be connected to the Si'seteffiSHäepeF ^ eHfeü 2 is connected via the housing bore 8 to the pressure reducer 9, by means of which the bottle pressure is reduced to the necessary operating pressure. The relaxed compressed gas flows through the metering bore 10 in the line 11 to the pressure chamber 12 above the sound membrane 13 * which is also arranged in the housing 5. The sound membrane rests against the sealing edge 14 of the connecting piece 15 for the horn horn 17. Due to the air flowing into the pressure chamber 12, the
Membran Ij5 abgehoben. Durch den regelmäßig wiederkehrenden plötzlichen Druckausgleich zwischen Druckkammer 12 und Luftraum l6 im Signalhorntrichter 17 wird der Luftraum l6 zum Schwingen gebracht. Das Signalhorn 17 ist gegenüber dem Rohrstutzen 15a verschiebbar, wobei eine Druckfeder l8 das Signalhorn jeweils in die dargestellte Lage zu drücken versucht. Wenn der Gerätträger das Signalhorn am mittleren balligen Teil 19 anfaßt und hin- und herschiebt, ändert sich der Signalton kontinuierlich , so daß ein auf- und abschwellender Heulton entsteht.Membrane Ij5 lifted off. The regularly recurring sudden pressure equalization between the pressure chamber 12 and the air space 16 in the horn funnel 17 causes the air space 16 to vibrate. The signal horn 17 is displaceable with respect to the pipe socket 15a, a compression spring 18 trying to push the signal horn into the position shown. When the device wearer grips the horn on the central spherical part 19 and pushes it back and forth, the signal tone changes continuously , so that a rising and falling howling is produced.
