Description
Es sind bereits Glühlampenfassungen bekannt, bei welchen das unbefugte Herausdrehen der Glühlampen aus ihrer Fassung durch Klemmkegel oder Exzenter verhindert wird. Der Erfindungsgegenstand stellt eine besondere Ausführungsform eines Isolierringes dar, der die angegebene Aufgabe auf einfache Weise löst, an jeder Fassung angebracht werden kann und keine Änderung oderThere are already incandescent lamp sockets known in which unauthorized unscrewing the incandescent lamps are prevented from their socket by clamping cones or eccentrics. The subject matter of the invention represents a special embodiment of an insulating ring that solves the specified problem in a simple manner, attached to each socket can be and no change or
ίο Neukonstruktion der üblichen Fassungen erforderlich macht.ίο New design of the usual versions required power.
Der Erfindungsgegenstand ist auf der Zeichnung dargestellt.. Zwischen zwei Blechen α (Fig. i), welche durch vier Bolzen b fest miteinander verbunden sind, ist eine Feder c so angeordnet, daß ihre beiden Enden auf zwei gezahnte Klemmkegel oder Exzenter d drücken. Das Ganze bildet also ein halbkreisförmiges Segment. Zwei solcher Segmente sind in einem Isolierring untergebracht (s. auch Fig. 2). Die vier Klemmkegel d werden beim Einschrauben des Isolierringes oder der Lampe selbsttätig zurückgedrückt; bei jeder Rückwärtsbewegung jedoch drücken sich ihre Zähne in das Gewinde des Gewindekorbes der Fassung bzw. des Sockels der Glühlampe ein und; machen so für einen Unbefugten ein Herausschrauben der Lampe unmöglich.The subject of the invention is shown in the drawing. Between two metal sheets α (Fig. I), which are firmly connected by four bolts b , a spring c is arranged so that its two ends press on two toothed clamping cones or eccentrics d. So the whole thing forms a semicircular segment. Two such segments are housed in an insulating ring (see also Fig. 2). The four clamping cones d are automatically pushed back when the insulating ring or the lamp is screwed in; with each backward movement, however, their teeth press into the thread of the threaded basket of the socket or the base of the light bulb and; make it impossible for an unauthorized person to unscrew the lamp.
Das Auswechseln der Lampe geschieht nach Lüftung der Feder c (in Fig. 1 durch eine punktierte Linie dargestellt) durch einen besonderen Schlüssel.The lamp is replaced after the spring c has been released (shown in FIG. 1 by a dotted line) using a special key.
Fig. 2 zeigt eine mit dem vorbeschriebenen Erfindungsgegenstand ausgestattete Fassung mit eingeschraubter Glühlampe.Fig. 2 shows a version equipped with the above-described subject matter of the invention with screwed-in bulb.
Fig. 3 stellt schematisch eine andere Anordnung dar, bei der die vier Klemmkegel senkrecht übereinanderliegen. Die Feder c ist bei dieser Anordnung um die gemeinsame Achse gewickelt.Fig. 3 shows schematically another arrangement in which the four clamping cones are perpendicular to each other. In this arrangement, the spring c is wound around the common axis.
