von Glühlampen.of incandescent lamps.
Mit der Verdrängung der billigen Kohlenfadenglühlampe durch die teuere Metalldraht- und Halbwattlampe hat sich in steigendem Maße das Bedürfnis nach einer Sicherungsvorrichtung gebildet, welche die wertvolle Glühlampe gegen Entwendung schützt.With the replacement of the cheap carbon filament incandescent lamp by the expensive metal wire and half-watt lamp, the need for a safety device has increased formed, which protects the valuable light bulb against theft.
Diesem Zwecke dient der Gegenstand der vorliegenden Erfindung, dessen Wesen darin besteht, daß die an sich in bekannter Weise ίο um den zu sichernden. Körper sich legende Sperrfeder in dem mit Linksgewinde mit der übrigen Fassung verbundenen Isolierring angeordnet ist. This is the purpose of the subject matter of the present invention, its essence therein consists that the in itself in a known manner ίο to be secured. Body settling down Locking spring is arranged in the insulating ring connected to the rest of the socket with a left-hand thread.
In den Fig. ι und 2 ist die Erfindung beispielsweise dargestellt. Es bezeichnet a die zu sichernde Glühlampe, die in die mit Sicherung ausgerüstete Fassung b eingeschraubt ist. Diese Fassung, die. im übrigen in bekannter Weise ausgestaltet ist, trägt in demIn Figs. Ι and 2, the invention is shown for example. It denotes a light bulb which is to be secured, which is screwed into the b equipped with fuse holder. This version that. is otherwise designed in a known manner, carries in the
ist, um ein Mitausschrauben gleichzeitig mit der Lampe unmöglich zu machen, mit Linksgewinde in die Fassung eingeschraubt. Die Sicherungsfeder d ist in bekannter Weise ausgestaltet und in einer Aussparung e im Isolierring untergebracht. Die Feder ist an einem Ende durch die Verschraubung f mit dem Isolierring· fest verbunden, umspännt den Lampensockel und ragt mit dem andern freien Ende i in den Ringis screwed into the socket with a left-hand thread to make it impossible to unscrew it at the same time as the lamp. The safety spring d is designed in a known manner and housed in a recess e in the insulating ring. The spring is firmly connected to the insulating ring at one end by the screw connection f , it spans the lamp base and the other free end i protrudes into the ring

hinein. Die Wirkungsweise dieser Einrichtung ist die folgende: Beim Einschrauben der Lampe, welches nach Fig. 2 im Sinne des Pfeiles g erfolgt, öffnet sich die Feder und das Einschrauben geht frei vonstatten. Beim Ausschrauben der Lampe, also beim Drehen im Sinne des Pfeiles h, nimmt der Lampensockel infolge der Reibung die Feder mit, diese klemmt sich fest um die Lampe und verhindert so ein Drehen derselben. Da die Feder selbst an dem mit Linksgewinde befestigten Isolierring angeordnet ist, kann ein unbefugtes Ausschrauben der Lampe nicht stattfinden. Ein Ausschrauben der Lampe ist nur dann möglich, wenn die Feder an ihrem freien Ende i gelüftet wird. Um dieses dem Befugten zu ermöglichen, wird durch die Öffnung k des Isolierringes und die Öffnung I in dem befestigten Ende der Feder in bekannter Weise ein Schlüssel eingeführt, der mit seinem Barte die Feder lüftet. ■into it. The mode of operation of this device is as follows: When the lamp is screwed in, which takes place according to FIG. 2 in the direction of arrow g , the spring opens and screwing in takes place freely. When the lamp is unscrewed, i.e. when it is turned in the direction of arrow h, the lamp base takes the spring with it due to the friction, which clamps tightly around the lamp and thus prevents it from turning. Since the spring itself is arranged on the insulating ring, which is fastened with a left-hand thread, the lamp cannot be unscrewed by unauthorized persons. The lamp can only be unscrewed if the spring is released at its free end i . In order to make this possible for the authorized person, a key is inserted in a known manner through the opening k of the insulating ring and the opening I in the attached end of the spring, which releases the spring with its beard. ■
