Description

Fortschellkontakt für elektrische Alarmglocken. Den Gegenstand der Erfindung bildet eine Stromschlußvorrichtung zum Einschalten elektrischer Alarmglocken, welche bezweckt, ein dauerndes Läuten bis zur willkürlichen Abstellung herbeizuführen, auch wenn nur ein ganz kurzer, rasch unterbrochener Kontakt stattgefunden hat.Rapid contact for electrical alarm bells. The subject of the Invention forms a current-closing device for switching on electrical alarm bells, which aims to bring about a permanent ringing until arbitrary shutdown, even if there was only a very brief, quickly interrupted contact.

Diese Alarmglocke soll verhüten, daß beispielsweise ein Dieb sich in einen Stall, ein Zimmer oder eine Wohnung einschleicht, wobei zwar durch öffnen der Tür oder des Fensters ein elektrisches Läutewerk in Tätigk eit gesetzt wird, das aber sofort nach dem Wiederschließen der Tür -wieder verstummt, s-i daß die Bewohner kaum davon geweckt werden können, wonach dann der Dieb nach Zcrstörung der Leitung seine Beute in Sicherheit bringen und unbemerkt wieder verschwinden kann. Bei Einschaltung des Apparates in die Leitung wird jedoch ein Alarmsignal in der Wohnung ununterbrochen fortgesetzt ertönen, bis es der Inhaber der Wohnung wieder abstellt. Vorrichtungen dieser Art sind bekannt. Die Erfindung bezieht sich auf eine besonders einfache AusfUhrungsform.This alarm bell is intended to prevent a thief, for example sneaking into a stable, a room or an apartment, although by opening it an electric bell is activated on the door or window, But that immediately after the door is closed again -dushes again, s-i that the Residents can hardly be awakened by it, after which the thief after destruction the line bring his prey to safety and disappear again unnoticed can. However, when the device is switched on to the line, an alarm signal is given The sound continues uninterruptedly in the apartment until the owner of the apartment does turns off again. Devices of this type are known. The invention relates to on a particularly simple embodiment.

a ist ein Elektromagnet, welcher einem Anker*c gegenübersteht und diesen Anker bei der Erregung sofort anzieht. An dem Anker c befindet sich eine Rolle d aus nicht magnetisch werdendem Metall; diese Rolle stützt den -Anker e eines zweiten Elektromagneten b in seiner angehobenen Stellung; sobald jedoch üer Anker c angezogen wird, gleitet die Rolle d unter dem Anker e fort und läßt diesen herabfallen.. Der Anker e wird von einer Feder f getragen, welche nun durch das Gewicht des Ankers niedergedrückt wird und die Stellschraube h berührt, wodurch die Stromleitung zur Alarmglocke l geschlossen -wird und letztere in der Wohnung dauernd ertönt. (Schaltungsschema Fig. 2). Zerstört dann der Dieb die Leitung g, welche den Elektromagneten a erregt, so ertönt doch das Alarmsignal der Glocke l ununterbrochen fort.a is an electromagnet which faces an armature * c and immediately attracts this anchor upon excitation. At the anchor c there is a Roll d made of non-magnetic metal; this role supports the anchor e one second electromagnet b in its raised position; as soon as over anchor c is tightened, the roller d slides away under the anchor e and lets it fall down .. The anchor e is carried by a spring f, which is now due to the weight of the anchor is depressed and touches the adjusting screw h, causing the power line to Alarm bell l is closed and the latter sounds continuously in the apartment. (Circuit diagram Fig. 2). If the thief then destroys the line g, which excites the electromagnet a, so the alarm signal of the bell continues to sound uninterrupted.

Das Abstellen der Alarmglocke l erfolgt durch den Abstellkontakt m, indem der Elektromagnet b erregt wird, der seinen Anker e wieder in die Sperrlage zurückführt.The alarm bell l is switched off by the switch-off contact m, by energizing the electromagnet b, which moves its armature e back into the blocking position returns.
