Description

Akustischer Feuermelder Die Erfindung betrifft einen akustischen Feuermelder, der aus einem oder mehreren Sprengkörpern besteht, die bei Erreichung einer gefährlichen Temperatur gesprengt werden.Acoustic fire alarm The invention relates to an acoustic fire alarm, which consists of one or more explosive devices, which when reaching a dangerous Temperature to be blown.

Die bisher bekannten Feuermelder dieser Art bestehen aus ziemlich großen Sprengkörpern, die beispielsweise an den Wänden des zu sichernden Raumes aufgehängt werden. Diese Sprengkörper können eventuell mittels Zündschnüren miteinander verbunden sein, wodurch die Empfindlichkeit gegenüber kleineren Feuern erhöht wird. Die genannten, mit Zündschnüren ausgestatteten Sprengkörper verunzieren jedoch den Raum. Außerdem geben die großen Sprengkörper leicht zu Unfällen Anlaß.The previously known fire alarms of this type consist of pretty much large explosive devices, for example on the walls of the room to be secured to be hung. These explosive devices can possibly be connected to one another by means of fuses connected, which increases the sensitivity to smaller fires. However, the above-mentioned explosive devices equipped with fuses spoil the Space. In addition, the large explosive devices easily give rise to accidents.

Die Erfindung bezweckt,- einen Feuermelder der vorgenannten Art zu schaffen, der bedeutend billiger, leichter anbringbar und außerdem beinahe unsichtbar und gänzlich ungefährlich ist.The invention aims to provide a fire alarm of the aforementioned type create that is significantly cheaper, easier to install and also almost invisible and is completely harmless.

Dies ist erfindungsgemäß dadurch erreichbar, daß der Feuermelder aus einer größeren Anzahl Knallscheiben oder ähnlichen kleinen Sprengkörpern besteht, die in der Farbe zum Anstreichen z. B. der Wände und Decken eingebettet sind.According to the invention, this can be achieved by turning the fire alarm off there is a large number of blast disks or similar small explosive devices, in the color for painting z. B. the walls and ceilings are embedded.

Dieser Feuermelder kann mit ganz geringen Kosten hergestellt und angebracht werden. Eine ausreichende Menge von Knallscheiben braucht nur der Farbe zugesetzt zu werden, mit der die Decken, die Wände oder das Inventar eines Raumes angestrichen werden sollen. In der getrockneten Farbe sind die Knallscheiben beinahe unsichtbar und können unter gewissen Umständen sogar eine dekorative Wirkung hervorbringen. Auf Grund der großen Anzahl über den Raum gleichmäßig verteilter Knallscheiben wird der Feuermelder darüber hinaus sehr empfindlich.This fire alarm can be manufactured and installed at a very low cost will. A sufficient amount of pop disks only needs to be added to the paint to be used to paint the ceilings, walls or inventory of a room should be. In the dried paint, the pop disks are almost invisible and can even produce a decorative effect under certain circumstances. Due to the large number of pop disks evenly distributed over the room the fire alarm is also very sensitive.

Jede der Knallscheiben kann eventuell so gestaltet sein, daß sie bei Zündung zwei oder mehr Sprengungen abgibt, wodurch das Feuersignal eindeutiger wird und nicht mißverstanden werden kann.Each of the pop disks can possibly be designed so that they at Ignition gives off two or more detonations, making the fire alarm clearer and cannot be misunderstood.
