Description

Verschließbarer Schutzkorb mit Signalvorrichtung, um einen Diebstahl elektrischer Glühlampen anzuzeigen. Der vorliegende Erfindungsgegenstand stellt einen verschließbaren Schutzkorb für elektrische Glühkörper dar mit einer Kontakteinrichtung zum Melden der versuchten Entwendung der Glühlampe.Lockable protective cage with signal device to prevent theft electric light bulbs. The present subject matter of the invention represents a lockable protective cage for electrical incandescent bodies with a contact device to report the attempted theft of the light bulb.

Gemäß der Erfindung wird der Schutzkorb mittels einer verschließbaren Rohrschelle an das Pendelrohr angeschlossen, so daß er nicht entfernt werden kann. Gleichzeitig ist die Rohrschelle mit einer Kontakteinrichtung versehen, die beim Öffnen des Scharniers den Signalstromkreis schließt.According to the invention, the protective cage by means of a lockable Pipe clamp connected to the pendulum tube so that it cannot be removed. At the same time, the pipe clamp is provided with a contact device that is used in Opening the hinge closes the signal circuit.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise veranschaulicht, und. es zeigt Abb. z verschließbaren Schutzkorb im Gebrauch, Abb. 2 Ansicht der verschließbaren Schelle, Abb. 3 Grundriß zu Abb. 2, Abb. a Ansicht des Verschlußriegels nebst Verschlußdraht des Schutzkorbes, Abb.5 Querschnitt durch den Verschluß-Tiegel, Abb. 6 Ansicht des hinteren Scharnierteiles mit elektrischem Kontakt, Abb. 7 Querschnitt zu Abb. 6.In the drawing, the subject matter of the invention is illustrated, for example, and. it shows Fig. z lockable protective cage in use, Fig. 2 view of the lockable clamp, Fig. 3 plan for Fig. 2, Fig. a View of the locking bolt together with the locking wire of the protective cage, Fig. 5 cross-section through the locking crucible, Fig. 6 View of the rear hinge part with electrical contact, Fig. 7 cross section to Fig. 6.

Der Schutzkorb besitzt zwei verstärkte Verschlußdrähte =, die mit Bundenn versehen sind. Diese greifen in die Vertiefungen der Verschlußschelle a, welche mit dem Deckel b im Punkte c scharnierartig verbunden-ist. Mit dem Scharnier ist der Kontaktfinger d verbunden. Dieser wird bei dem geringsten öffnen d.et Schelle mit der Kontaktplatte e, welche mir der durch Isolierurig h geschützten Feder f in Verbindung steht, in Berührung kommen und den Strom durch den Kontaktstift g- nach der Kontaktschraube m leiten, an welchem der Signalleitungsdraht angeschlossen wird. Der Verschluß der Schellenteile a und b erfolgt durch einen Drei- oder Vierkantdrücker, mit dem der Stift gedreht werden kann. Der Stift ist mit einer mit einem Einschnitt versehenen Zunge o verbunden, die in das Verschlußblech p, das am Scharnierteil b angeordnet ist, greift. Durch diese doppelte Sicherung wird die Gewähr geschaffen, daß selbst beim Versuch der Öffnung des Schutzkorbes der unbefugte Eingriff gemeldet wird.The protective cage has two reinforced locking wires = which are provided with collars. These grip into the recesses of the locking clip a, which is connected in a hinge-like manner to the cover b at point c. The contact finger d is connected to the hinge. With the slightest opening of the clamp, this will come into contact with the contact plate e, which is connected to the spring f protected by insulation h , and conduct the current through the contact pin g- to the contact screw m, to which the signal wire is connected will. The clamp parts a and b are closed by means of a triangular or square pusher with which the pin can be rotated. The pin is connected to a tongue o provided with an incision which engages in the closure plate p which is arranged on the hinge part b. This double safeguard ensures that the unauthorized intervention is reported even when attempting to open the protective cage.
