Alarmvorrichtung zum Anzeigen von Einbruchsversuchen.
Die Erfindung betrifft eine Alarmvorrichtung, welche bei Versuchen, die Füllung einer Türe aus dem Rahmen zu entfernen, sofort in Tätigkeit tritt. Sie besteht aus einer an dem Türrahmen angebrachten Kontaktvorrichtung für einen elektrischen Alarmstromkreis, deren Schliessorgan bei normaler Lage durch Abstützung gegen die Türfüllung in der Offenstellung gehalten und durch Wegnahme der Füllung geschlossen wird.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes veranschaulicht, und zwar zeigt Fig. i die Vorrichtung in Draufsicht und Fig. 2 im Vertikalschnitt.
EMI1.1
an welche die zur Stromquelle f und Alarmglocke g führende Leitung angeschlossen ist. Die Feder d übergreift die Feder e und besitzt eine Bohrung, in welcher ein mit zwei Köpfen i, k versehener Stift h spielt. Dieser reicht durch Bohrungen der Schiene b und der Platte a bis zur Türfüllung j. Zwischen den Kopf k des Stiftes und die Schiene b ist eine Druckfeder l eingebaut, die den Stift stets an die Türfüllung andrückt und die bei normaler Stellung gespannt ist.
Bei Wegnahme der Türfüllung bewirkt die Feder, dass der Stift der Füllung in der Bewegungsrichtung nachfolgt, wodurch er die Kontaktfeder d mit der Feder e in Berührung bringt und den Alarmstromkreis schliesst.

Alarm device to indicate attempted break-ins.
The invention relates to an alarm device which immediately comes into operation when attempts are made to remove the filling of a door from the frame. It consists of a contact device attached to the door frame for an electrical alarm circuit, the closing element of which is held in the open position in the normal position by being supported against the door panel and is closed by removing the panel.
In the drawing, an embodiment of the subject matter of the invention is illustrated, namely FIG. 1 shows the device in plan view and FIG. 2 shows in vertical section.
EMI1.1
to which the line leading to the power source f and alarm bell g is connected. The spring d overlaps the spring e and has a bore in which a pin h provided with two heads i, k plays. This extends through holes in the rail b and the plate a to the door panel j. A compression spring l is installed between the head k of the pin and the rail b, which always presses the pin against the door panel and which is tensioned in the normal position.
When the door panel is removed, the spring causes the pin to follow the panel in the direction of movement, bringing the contact spring d into contact with the spring e and closing the alarm circuit.
