aus ihrer Fassung.out of their composure. Gegenstand der Erfindung ist eine Fassung für elektrische Glühlampen, die mit einer Einrichtung zur Verhinderung unbefugter Entnahme der Lampen versehen ist. Dieselbe unterscheidet sich von bekannten ähnlichen Einrichtungen dadurch, daß der aus nachgiebigem Material hergestellte Isolierring geschlitzt ist und durch eine herumgelegte Rohr- ; schelle gegen den Gewindekorb der Fassung iThe invention relates to a socket for electric incandescent lamps with a device to prevent unauthorized removal of the lamps. The same is different from known similar ones Devices in that the insulating ring made of resilient material is slotted is and by a wrapped pipe; clamp against the threaded basket of the socket i to und den Lampenhals zusammengepreßt wird. , Der Erfindungsgegenstand ist auf der :to and the neck of the lamp is pressed together. , The subject of the invention is on the: Zeichnung dargestellt, und zwar zeigen die Abb. ι und 2 ein Ausführungsbeispiel in Sei- jDrawing shown, namely the Fig. Ι and 2 show an embodiment in Se- j tenansicht, teilweise geschnitten, und im i Querschnitt und Abb. 3 ein zweites Ausfüh- j rungsbeispiel ebenfalls im Querschnitt.ten view, partially in section, and in i cross section and Fig. 3 a second embodiment example also in cross section. Die Fassung selbst ist eine gewöhnliche Schraubfassung mit einem stromführenden Gewindekorb er, in welchen der Glühlampensockel b eingeschraubt wird, und einem Isolierring c. Der letztere besteht aus Vulkanfiber oder ähnlichem Isolierstoff und ist bei d «aufgeschnitten, so daß er federt; ferner ist er an der Innenseite des unteren Randes mit einem glatten zylindrischen Kranz e versehen, der sich an den ebenso gestalteten Lampenhals f anlegt. In einer ringförmigen Eindrehung an der Außenseite des Isolierringes c Hegt eine Schelle g, d. h. ein den Ring umfassendes Metallband, dessen seitwärts ragende Enden z. B. durch eine Kopfschraube h (Abb. ι und 2) miteinander ver- ; bunden sind. Der sechskantige Kopf dieser Schraube ist von einer lose zwischen ihn und \ das eine Bandende eingesetzten Kapsel i umgeben, während das Schattende der Schraube , in eine in das andere Bandende eingenietete ' runde Mutter k greift.The socket itself is an ordinary screw socket with a current-carrying threaded basket into which the bulb socket b is screwed, and an insulating ring c. The latter consists of vulcanized fiber or a similar insulating material and is cut open at d «so that it is resilient; Furthermore, it is provided on the inside of the lower edge with a smooth cylindrical rim e , which rests against the lamp neck f , which is also designed. In an annular recess on the outside of the insulating ring c huddles a clamp g, ie a metal band encompassing the ring, the laterally protruding ends z. B. by a head screw h (Fig. Ι and 2) with each other; are bound. The hexagonal head of this screw is surrounded by a loosely i between it and \ the capsule an end of tape used, while the shadowing of the screw engages in a k riveted in the other band end 'round nut. Durch Anziehen der Schraube h kann man die Enden der Schelle g zusammenziehen und dabei mittels der Schelle den Isolierring c auf dem Gewindekorb α und dem Lampenhals b gleichzeitig so festklemmen, daß ein Herausschrauben der Glühlampe aus der Fassung unmöglich ist. Um das Herausschrauben zu ermöglichen, muß man die Schraube Ii wieder lösen, was aber ebenso wie das Anziehen derselben nur mittels eines besonderen, in die Kapsel i und auf den Schraubenkopf passenden Steckschlüssels ausführbar ist.By tightening the screw h , the ends of the clamp g can be pulled together while using the clamp to clamp the insulating ring c on the threaded basket α and the lamp neck b at the same time so that it is impossible to unscrew the bulb from the socket. To enable unscrewing, the screw Ii must be loosened again, which, like the tightening of the same, can only be carried out by means of a special socket wrench that fits into the capsule i and onto the screw head. Bei dem Ausführungsbeispiel· nach Abb. "3 werden die Enden der Schelle g durch eine eingenietete Öse i zusammengehalten, deren beide Köpfe j e von einer Kapsel m umgeben sind, so daß sie ebenfalls nur mittels eines besonderen Werkzeuges gelöst \verden kann.In the embodiment according to Fig. 3, the ends of the clamp g are held together by a riveted eyelet i , the two heads of which are each surrounded by a capsule m so that they can also only be released by means of a special tool. Paten τ-Anspruch:Sponsorship τ claim: Einrichtung zur Verhinderung der unbefugten Entnahme elektrischer Glühlampen aus ihrer Fassung durch einen den Gewindekorb der Fassung und den Lampensockel umgreifenden Ring, dadurch gekennzeichnet, daß der aus Vulkanfiber oder einem anderen elastischen Isolierstoff bestehende Isolierung (e) aufgeschnitten und von einer Schelle (g·) umgeben ist, mittels deren er festgeklemmt werden kann, und deren Enden miteinander verschraubt, vernietet oder sonstwie verbunden werden.Device to prevent the unauthorized removal of electric light bulbs from its socket through a ring encompassing the threaded basket of the socket and the lamp base, thereby characterized in that the one made of vulcanized fiber or another elastic insulating material Cut open the existing insulation (e) and surround it with a clamp (g ·) by means of which it can be clamped, and the ends of which are screwed, riveted or otherwise get connected.
