Description

Vorliegende Erfindung beMfft eine Vorrichtung, welche im Innern eines Schaufensterrahmens angebracht ist und beim Zerschlagen der Scheibe einen Alarmapparat in Tätigkeit setzt. Auf der Zeichnung ist die Erfindung schematisch dargestellt, und zwar zeigt die Abbildung ein Schaufenster mit bloßgelegter Alarmvorrichtung.
Der Rahmen der Scheibe α ist', soweit nötig,The present invention concerns a device which is mounted inside a shop window frame and which activates an alarm apparatus when the window is broken. In the drawing, the invention is shown schematically, namely the figure shows a shop window with an exposed alarm device.
The frame of the disk α is', if necessary,

ίο zur Aufnahme der Sicherheitsvorrichtung hohl gestaltet. Scheibeklemmen b, welche mit einer öse versehen sind, sind in Abständen von etwa 20 cm im Hohlrahmen c an der Fensterscheibe α befestigt. In denselben Abständen sind auch Schnurringe d in der Holzwand des Rahmens befestigt. Im ersten Ring d1 ist die Schnur e !befestigt, welche im Zickzack durch die ösen der Klemmen & und die Ringed! durchgezogen ist. An einer beliebigen Stelleίο designed hollow to accommodate the safety device. Window clamps b, which are provided with an eyelet, are attached to the window pane α at intervals of about 20 cm in the hollow frame c. Cord rings d are also attached to the wooden wall of the frame at the same intervals. The cord e ! Is fastened in the first ring d 1 , which zigzags through the eyelets of the clamps & and the Ringed! is pulled through. Anywhere

ao trägt die Schnur an einer Rolle f1 ein Gewicht /, welches in der Bereitschaftslage der Sicherung die Schnur durchweg, in der zickzackförmigen Lage gespannt hält, wobei diese mit.ao carries the cord on a reel f 1 a weight / which in the standby position of the fuse keeps the cord taut throughout, in the zigzag position, this with.

ihrem einen Ende an den· letzten Ring d2 befestigt ist.one end is attached to the last ring d 2 .

Wenn nun bei einem Einbruch die strahlenförmige Zerstörung der Fensterscheibe α eintritt, werden sich von letzterer einzelne Splitter lösen. Jeder Splitter, welcher dann keine Verbindung mit der Scheibe mehr hat, wird nunmehr durch die Schnur unter Wirkung des Gewichts f angezogen, so daß die Schnur an den Splitterstellen ihre Zickzackform verliert und das Gewicht f ein wenig sinken kann, um z. B. einen elektrischen Kontakt für einen Alarmglockenstromkreis !herzustellen.If the radial destruction of the window pane α occurs during a break-in, individual splinters will detach from the latter. Each splinter, which then no longer has a connection with the disc, is now attracted by the cord under the action of the weight f , so that the cord loses its zigzag shape at the splinter points and the weight f can drop a little to z. B. to establish an electrical contact for an alarm bell circuit!

Die dargestellte Vorrichtung stört! nicht beim Dekorieren oder Putzen des Schaufensters und kann völlig unsichtbar angebracht werden.The device shown is annoying! not when decorating or cleaning the shop window and can be attached completely invisible.

Claims (1)

Patent-Anspruch:Patent claim: Alarmsicherung gegen Schaufenster-Einbruch, dadurch gekennzeichnet, daß im hohlen Fensterrahmen (c) eine unter Wirkung eines Spanngewichtes (f) stehende Schnur (e) angeordnet ist, welche mit derAlarm protection against break-ins in shop windows, characterized in that a cord (e) under the action of a tension weight (f) is arranged in the hollow window frame (c), which cord (e) is connected to the Fensterscheibe (α) einerseits und dem | Rahmen (c) anderseits an verschiedene j Punkte, im Zickzack verbunden ist, so daß beim Zerschlagen der Scheibe (α) die sich von ihr loslösenden Splitter, an denen die Schnur (e) noch angreift, deren teilweise Geradstreckung und dadurch die Senkung des Spanngewichtes zwecks Auslösung eines elektrischen Alarmkontaktes o. dgl. zulassen. Window pane (α) on the one hand and the | Frame (c), on the other hand, is connected in a zigzag at different j points, so that when the pane (α) is broken, the splinters detaching from it, on which the cord (e) still grips, their partial straightening and thus the lowering of the tension weight for the purpose of triggering an electrical alarm contact or the like. ιι
