Die den Gegenstand der Erfindung bildendeForming the subject of the invention
Lampenfassung besteht aus einem Fuß d, auf welchem die Gewindehülse e befestigt ist, dem diese Teile umschließenden Mantel_/ und dem Porzellanring g. The lamp socket consists of a foot d on which the threaded sleeve e is attached, the jacket_ / surrounding these parts and the porcelain ring g.
In die Gewindehülse e wird der Sockel h der Glühlampe / eingeschraubt.The base h of the light bulb / is screwed into the threaded sleeve e.
Die Gewindehülse e ist an einer Stelle verstärkt und durchbohrt, so daß in diese Öffnung eine Schraube α eingefügt werden kann, durch welche die eingeschraubte Glühlampe h i in ihrer Lage festgehalten wird. Geschieht das Einschrauben der Schraube a so weit, daß dieselbe gegen den Sockel h der Glühlampe i gepreßt wird, dann ist die Glühlampe gegen jegliche Drehung gesichert.The threaded sleeve e is reinforced and drilled through at one point so that a screw α can be inserted into this opening, by means of which the screwed-in incandescent lamp hi is held in place. Happens the screwing of the screw a so far that the same h against the base of the bulb is pressed i, then the bulb is secured against any rotation.
Das nach außen stehende Ende der Schraube a ist so gestaltet, daß es das Aufstecken eines Schlüssels c ermöglicht, durch welchen die Drehung der Schraube von außen bewirkt wird. Das Ende der Schraube α ist nur so lang, daß es noch von dem Mantel f bedeckt wird. Letzterer ist deshalb mit einer Öffnung b versehen, um das Durchstecken des Schlüssels c zu ermöglichen. Sobald die Lampe i durch die Schraube α festgehalten wird, ist es nicht möglich, die Lampe i ohne Zuhülfenahme des Schlüssels c zu lösen.The outwardly protruding end of the screw a is designed in such a way that it enables a key c to be inserted, by means of which the rotation of the screw is effected from the outside. The end of the screw α is only so long that it is still covered by the jacket f . The latter is therefore provided with an opening b to enable the key c to be pushed through. As soon as the lamp i is held in place by the screw α , it is not possible to loosen the lamp i without the aid of the key c.
Das Auswechseln oder Entfernen der Lampe i aus der Fassung durch Unbefugte ist dadurch unmöglich gemacht.This makes it impossible for unauthorized persons to replace or remove the lamp i from the socket.
Es sind bereits Sicherungen gegen unbefugtes Auswechseln von Glühlampen bekannt, bei denen auch erst durch Anwendung eines besonderen Schlüssels ein Auswechseln ermöglicht wird.There are already fuses against unauthorized replacement of light bulbs known which can only be replaced by using a special key will.
Alle diese Vorrichtungen lassen sich jedoch nicht, wie die vorliegende Sicherung, ohne weiteres an die gebräuchlichen Fassungen anbringen. Sie erforderten vielmehr wesentliche bauliche Abänderungen der Fassung oder des Lampensockels oder beider Teile.However, like the present fuse, all of these devices cannot be without Attach another to the common sockets. Rather, they required essentials structural changes to the socket or the lamp base or both parts.
Das vollständige Verdecken der Schraube a kann leicht durch Drehen des Mantels f auf dem Fuß d bewirkt werden.The complete obscuration of the screw a can easily be effected by turning the casing f on the foot d .
Soll die Lampe i ausgewechselt oder entfernt werden, so muß zunächst der Mantel f so gedreht werden, daß die Öffnung b der Schraube α gegenüber tritt, dann wird der Schlüssel c auf das Ende der Schraube α durch die Öffnung b im Mantel f aufgesteckt und die Schraube α gelöst. Sobald dies geschehen ist, kann die Lampe i aus der Gewindehülse e ausgeschraubt werden.If the lamp i is to be replaced or removed, the jacket f must first be rotated so that the opening b of the screw α occurs opposite, then the key c is placed on the end of the screw α through the opening b in the jacket f and the Loosened screw α . As soon as this has been done, the lamp i can be unscrewed from the threaded sleeve e .
