Die Vorrichtung hat die Bestimmung, Läden gegen Einbruchsdiebstähle zu sichern. Zu diesem Zweck wird dieselbe im unteren Rahmen des Rollladens eingelassen. Sie setzt sich zusammen aus dem eigentlichen Schlofs und einem unter dem Rollladen befestigten Zapfen. Bei heruntergelassenem Rollladen drückt dieser durch den Zapfen F mittelst eines im Schlofs befindlichen Bolzens E mit Stumpfkante einen Leitungsstift c heraus, welcher mit seinem Ende k, an welchem ein zur Batterie führender elektrischer Leitungsdraht befestigt ist, · eine vorspringende Metallfeder berührt, von welcher aus ein Leitungsdraht zur Glocke führt und so den Ruhestrom schliefst bezw. den Arbeitsstrom durch Abhebung von einer Metallplatte, welche ebenfalls durch einen Leitungsdraht mit der Glocke verbunden ist, unterbricht. Wird der Rollladen aufgehoben, so springt durch die Spiralfedern b und d der Bolzen sowie der Leitungsstift wieder in seine ursprüngliche Lage zurück, wobei der Ruhestrom wieder unterbrochen bezw. der Arbeitsstrom geschlossen wird, und die Glocke ertönt. The device is intended to secure shops against burglary. For this purpose, the same is embedded in the lower frame of the roller shutter. It is made up of the actual castle and a pin fastened under the roller shutter. When the roller shutter is lowered, it pushes out a lead pin c through the pin F by means of a bolt E with a blunt edge located in the lock, which at its end k, to which an electrical lead wire leading to the battery is attached, touches a projecting metal spring, from which a Lead wire leads to the bell and so the quiescent current closes or. the working current is interrupted by lifting it off a metal plate, which is also connected to the bell by a lead wire. If the roller shutter is lifted, the coil springs b and d jumps the bolt and the line pin back into its original position, with the quiescent current being interrupted again. the operating current is closed and the bell sounds.
