Description
Die Erfindung-bezieht sich auf eine Vorrichtung zur Verhütung des unbefugten Herausnehmens von elektrischen Glühlampen aus ihrer Fassung. Die Vorrichtimg soll den Diebstahl, von Glühlampen erschweren, der bekanntlich durch die leichte Herausschraub-· barkeit derselben aus der Fassung sehr gefördert wird. Es ist bereits bekannt, Glühlampen zu diesem Zwecke dadurch zu ^schützen, daß man den Glaskörper der Lampe oder ihren Sockel mit der Lampenfassung durch irgendwelche geeigneten Sperrqrgane sichert. Die vorgeschlagenen Mittel sind jedoch verhältnismäßig umständlich und bei Beschaf-The invention relates to a device to prevent unauthorized removal of electric light bulbs their frame. The device should make the theft of light bulbs more difficult is known to be greatly promoted by the ease with which it can be unscrewed from the socket will. It is already known to protect incandescent lamps for this purpose by that one secures the glass body of the lamp or its base with the lamp socket by any suitable locking devices. However, the proposed means are relatively cumbersome and

Der Erfindung gemäß soll in geringem Abstande unter der Einschrauböffnung für das Glühlampengewinde ein feststehender Blechring g (s. Fig. ) angeordnet sein, der irgendwie mit der feststehenden Lampenarmatur, ζ-. B. durch Arme h, verbunden ist. Die Öffnung dieses Blechringes gestattet an sich das freie Aus- und Einschrauben" der Birne. Bringt man· jedoch auf ihrem Sockelgewinde einen Ring i an, der lose aufliegt und bis zu dem untersten Gewindegang geschraubt werden kann, so verhindert dieser Ring, ohne das Hinejnschraüben der Birne zu beeinträchtigen, deren Herausschrauben, indem er sich auf den feststehenden Blechring g auflegt und an ihm festklemmt. Die Glühlampe kann dann nur um ein geringes! Maß gedreht werden. According to the invention, a fixed sheet metal ring g (see FIG.) Should be arranged at a short distance below the screw-in opening for the incandescent lamp thread, which somehow connects to the fixed lamp fitting, ζ-. B. is connected by arms h . However, the opening of this metal ring be carried on the free initial and screwing "of the bulb. Bring man · on its base threaded a ring i on, rests loosely and can be screwed up to the lowermost thread, this ring prevents, without the Hinejnschraüben of the bulb, unscrewing it by placing itself on the fixed sheet metal ring g and wedging it. The light bulb can then only be rotated by a small amount.
Die Arme h des Blechringes sind an ihren umgebogenen Enden zweckmäßig noch mit Öffnungen zum Durchtritt der drei Halteschrauben / des Schirmes e versehen, so daß der Ring auch mit dem Schirm noch nicht ohne . weiteres abgenommen werden kann, vielmehr zu diesem'Zwecke auch noch die drei Schrauben zu lösen sind.The arms h of the sheet metal ring are expediently provided at their bent ends with openings for the passage of the three retaining screws / the screen e , so that the ring is not yet without the screen. further can be removed, rather the three screws must also be loosened for this purpose.
