Gegenstand der Erfindung bildet "eine Vorrichtung zum selbsttätigen Alarmieren bei Feuersgefahr. Die Vorrichtung bezweckt die Überwachung größerer Räumlichkeiten, wie Wohnhäuser, Magazine, Warenlager, Schiffe o. dgl.,, und das rechtzeitige Ertönen zweier Alarmsignale, sobald eine Erhöhung der Temperatur über ein gegebenes Maximum stattfindet. 'The subject of the invention is "a device for automatic alarming Fire hazard. The device aims to monitor larger rooms, such as Houses, magazines, warehouses, ships or the like, and the timely sound of two Alarm signals as soon as the temperature rises above a given maximum. '

ίο Es sind Vorrichtungen bekannt, die dem Erfindungsgegenstande insofern nicht unähnlich sind, als auch bei ihnen die Feuersgefahr dadurch wahrnehmbar gemacht wird, daß in ein in Spannung gehaltenes und über Rollen geführtes Seil an mehreren Stellen schmelzbare Körper eingeschaltet sind, die bei einem bestimmten Wärmegrade durchschmelzen und dadurch eine Verschiebung des nunmehr entspannten Seiles und die Inbetriebsetzung einer Alarmvorrichtung bewirken.ίο There are devices known that the Subjects of the invention are not dissimilar to the extent that they also pose a risk of fire is made perceptible by the fact that in a tension held and over rolling guided rope are switched on in several places fusible bodies, which in one melt through certain degrees of warmth and thereby a shift of the now relaxed Effect rope and the activation of an alarm device.

Während jedoch diese Vorrichtungen sich nur zum Schütze einer einzigen Räumlichkeit einrichten lassen, soll der Erfindungsgegenstand dazu dienen, eine große Anzahl von Räumlichkeiten gleichzeitig zu schützen. Es kann in jedem Räume die Schmelzsicherung in Tätigkeit treten und die Inbetriebsetzung des Alarmsignales bewirken. Die Vorrichtung verbleibt immer, auch nach einer erfolgten Feuermeldung, in Arbeitsstellung, so daß auch für den Fall, daß an einer zweiten Stelle des gefährdeten Gebäudes ein Gefahrherd ent-35 However, while these devices can only be set up to protect a single room, the subject matter of the invention is intended to serve to protect a large number of rooms at the same time. The fuse can be activated in every room and activate the alarm signal. The device always remains, even after a successful fire alarm, in working position, so that even in the event that corresponds to a second location of the endangered building a danger oven 35

steht, das Alarmsignal abermals ertönt. Es kann hierbei in bekannter' Weise die' Anordnung getroffen werden, daß von einer Zentralstelle aus die Lage des Gefahrherdes bestimmt werden kann.stands, the alarm signal sounds again. It can here in a known 'way the' arrangement be made that determined from a central point of the location of the hazard can be.

. Die Zeichnung veranschaulicht den Erfindungsgegenstand schematisch im Vertikalschhitt. . The drawing illustrates the subject matter of the invention schematically in vertical section.

Die Vorrichtung besteht aus einem aus Röhren gebildeten hohlen Gerippe, in welchem die den Alarm veranlassenden Teile untergebracht sind. Das Gerippe setzt sich zusammen aus einem mittleren, lotrecht angeordneten Stamme a, an welchem sich die in beliebiger Höhe, Richtung, Länge und Anzahl angeordneten seitlichen Abzweigungen b radial · angliedern. Die Verbindung der Abzweigungen b mit dem mittleren Rohre geschieht durch eigenartige hohle Winkelstücke c, in welche der seitlich hervorstrebende Zweig mittels eines Kniegelenkes d eingefügt ist. Es ist dadurch die einzelne Abzweigung genügend befähigt, eine beliebige Richtung anzunehmen. Insonderheit kann die Neigung der einzelnen Abzweigung gegen die Horizontale nach Belieben eingestellt werden. An ihrem äußersten Ende sind die Abzweigungen durch eine Kapsel e abgeschlossen. Ebenso ist das untere Ende des Stammes α durch eine Kapsel/ abgeschlossen. 'The device consists of a hollow frame made of tubes in which the parts triggering the alarm are housed. The framework is composed of a central, vertically arranged trunk a, on which the lateral branches b, arranged at any height, direction, length and number, are radially attached. The connection of the branches b with the central tube is done by peculiar hollow angle pieces c, into which the laterally protruding branch is inserted by means of a knee joint d. As a result, the individual junction is sufficiently capable of taking any direction. In particular, the inclination of the individual junction can be adjusted to the horizontal at will. At their outermost end, the branches are closed by a capsule e . Likewise, the lower end of the trunk α is closed off by a capsule /. '

Durch den hohlen Stamm α ist ein Drahtseil ohne Ende g o. dgl. geführt. Dieses istA wire rope without end g or the like is passed through the hollow trunk α. This is

guided over a roller h arranged at the upper end of the trunk in its interior and via a roller i arranged at the lower end of the trunk in its interior. A weight k hangs on the roller i, which in the rest position serves to keep the wire rope • always in a tensioned state. The rope g bends sideways at every junction & of the framework over a pulley i1, penetrates ίο into the junction and there is wrapped around a pulley I, the pin of which is attached to a wire rope m, which is passed through the hollow junction b and attached to the pipe at the extreme end or the like depends. The weight k is given

1.5 therefore not only the wire rope g, but also the wire ropes m in a tensioned state.

Any number of short melting bodies η produced from a metal alloy with a very low melting point (about 80 ° C.) are switched on in each of the wire ropes m . In the drawing, these have the shape of a chain.

If the temperature rises at any point in the premises to be protected, the initially located melting body n will melt as soon as it is exposed to a temperature of over 80 ° C. This causes the voltage of the respective wire rope will go m lost. The roll I in question is drawn against the central trunk by the action of the weight k. The weight k falls downwards. There is a shift of the wire rope g , which closes the circuit of any conveniently arranged electrical alarm device and, if appropriately arranged, indicates the point of heating.

The tensioned state of the wire rope g as well as the ropes m is maintained even if the melting body η has melted due to excessive heating in any of the spaces to be protected. The protective system is therefore always in the working position and therefore able to indicate the risk of fire that has arisen in a second room.

A simultaneously sounding alarm clock with a striking mechanism is connected to the electrical alarm device, the release lever of which is connected to the wire rope g .

The device described makes any fire-extinguishing activity using water superfluous, since she gave the alarm long before the fire broke out, so that is the cause the heating, fermentation or the like. Can be eliminated before ignition.
