Description

Handbetriebenes Luftradsirenenkleingerät für Luftschutzzwecke Die Erfindung bezieht sich auf ein bandbetriebenes Luftradsirenenkleingerät für Luftschutzzwecke. Es ist bekannt, das Sirenenlaufrad durch Handantrieb, beispielsweise Handkurbel, in Bewegung zu setzen. Die bisher hierfür verwendeten Mittel sind aber so groß und unhandlich, däß sie besonders für den zivilen Luftschutz, erweiterten zivilen Luftschutz und Werkluftschutz nicht geeignet sind, weil diese Geräte entweder überhaupt nicht von einem Mann bedient werden können oder besonders festgemacht werden müssen; zum mindesten ist der die Sirene Bedienende in seiner Bewegung sehr beengt.Small hand-operated air wheel siren device for air raid protection purposes The invention relates to a small band-operated air wheel siren for air protection purposes. It is known to drive the siren wheel by hand drive, for example a hand crank, to set in motion. The funds used so far for this are so large and unwieldy, especially for civil air protection, extended civil air protection and air raid protection are unsuitable because these devices are not at all either can be operated by a man or must be specially secured; to the At least the person operating the siren is very restricted in his movement.

Demgegenüber kennzeichnet sich die Erfindung darin, daß das in einem mit dem Gehäuse fest verbundenen Lochring laufende Luftrad mittels einer Übersetzung durch Schnurzug mit Rückholfeder angetrieben wird.In contrast, the invention is characterized in that the in one with the housing firmly connected perforated ring running air wheel by means of a translation is driven by a pull cord with a return spring.

Es ist schon bekannt, andere Vorrichtungen durch Schnurzug anzutreiben, doch bietet gerade dieser Antrieb für Sirenen den wesentlichen Vorteil, daß bei ihrer Bedienung z. B. durch schnelles Ziehen und langsames Zurückgehen des Schnurzuges der wichtige Heulton der Sirene in äußerst einfacher Weise erreicht werden kann. Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise in Abb. i und Abb. 2 in verschiedenen Ansichten dargestellt.It is already known to drive other devices by pulling a cord, but it is precisely this drive for sirens that offers the essential advantage that with their operation z. B. by quickly pulling and slowly going back on the cord the important howling sound of the siren can be achieved in an extremely simple manner. In the drawing, the subject matter of the invention is shown, for example, in Fig. I and Fig. 2 shown in different views.

In dem Sirenengehäuse i läuft das Luftrad 2, das in. bekannter Weise bei hoher Umdrehung die Luft durch die Schlitze 3 des Lochringes preßt und dadurch den Heulton erzeugt. Das Luftrad 2 sitzt auf der Welle 4. Diese wird mittels einer Übersetzung 6 durch Schnurzug 8 mit Rückholfeder 7 in hohe Umdrehung versetzt. Hierdurch wird jedermann in die Lage versetzt, die Sirene durch einfachen Zug an der Schnur in Betrieb zu setzen, ohne dadurch irgendwie behindert zu werden. Um eine mißbräuchliche Verwendung der Alarmanlage zu verhüten, kann der Schnurzug durch eine Plombe gesichert werden.In the siren housing i, the air wheel 2 runs in a known manner at high rotation the air presses through the slots 3 of the perforated ring and thereby produces the howling sound. The air wheel 2 sits on the shaft 4. This is by means of a Gear ratio 6 set in high rotation by cord 8 with return spring 7. Through this everyone is able to activate the siren by simply pulling the cord put into operation without being hindered in any way. To an abusive To prevent use of the alarm system, the cord can be secured with a seal will.
