beider Stifte 11 miteinander leitend verbunden sind. Diese Ausführung bietet den Vorteil, dass der Ruhestrom schon bei einem teilweisen Herausziehen der Kontaktstifte 11 unterbrochen wird.
Zur Sicherung der hängenden oder stehenden Gegenstände gegen ein Wegnehmen kann auch ier Arbeitstrom einerA!armyonrichtung angewendet werden. In. diesem Falle wird unter dem Bilde oder dgl. ein Druckstift 14 (Fig. 7) angeordnet, der an einem federnden Kontakt 15

wodurch die Kontaktfeder 15 von dem Kontakt 16 weggedrückt und der Strom unterbrochen wird. Beim Wegnehmen des Bildes drückt die Feder 15 den Stift 14 aus der Büchse soweit heraus, bis sie, an den Kontakt 16 anliegt und den Strom der Alarmvorrichtung schliesst.
Die beschriebenen Ausführungsformen der elektrischen Sicherungsvorrichtung können unteremander zweckmässig kombiniert werden, wobei vorteilhafterweise eine Sicherung mit einem Ruhestromkreis und eine mit einem Arbeitsstromkreis gleichzeitig angewendet werden. Dabei werden die Leitungsdrähte der beiden Stromkreise derart zusammengedreht, dass die Drähte des Ruhestromes von den Drähten des Arbeitsstromes nicht unterschieden werden können.
In dieser Weise ist das Unterbrechen der Arbeitsstromdrähte ohne Beschädigung des Ruhestromkreises und dadurch ohne Betätigung der Alarmvorrichtung ausgeschlossen.
PATENT-ANSPRÜCHE :
1. Elektrische Sicherheitsvorrichtung gegen ein Wegnehmen von stehenden oder hängenden Gegenständen, wie Bilder oder dgl., dadurch gekennzeichnet, dass an der Wand oder dgl. hinter bzw. unter dem zu schützenden Gegenstande (2) Kontakte (3) für einen Ruhestrom angeordnet sind, die durch eine an dem Gegenstand angebrachte leitende Brücke (4) oder dgl. leitend verbunden sind, so dass beim Wegnehmen des Gegenstandes der Ruhestrom geöffnet und dadurch ein Signal ausgelöst wird.

both pins 11 are conductively connected to one another. This embodiment offers the advantage that the quiescent current is interrupted even when the contact pins 11 are partially pulled out.
To secure the hanging or standing objects against being taken away, a working current of an army device can also be used. In. In this case, a pressure pin 14 (FIG. 7) is arranged under the picture or the like, which is attached to a resilient contact 15
EMI2.1
whereby the contact spring 15 is pushed away from the contact 16 and the current is interrupted. When removing the picture, the spring 15 pushes the pin 14 out of the socket until it rests against the contact 16 and closes the current of the alarm device.
The described embodiments of the electrical safety device can be advantageously combined with one another, with one fuse with a closed circuit and one with an open circuit being advantageously used at the same time. The lead wires of the two circuits are twisted together in such a way that the wires of the quiescent current cannot be differentiated from the wires of the working current.
In this way, the interruption of the working current wires without damaging the closed circuit and thus without actuating the alarm device is excluded.
PATENT CLAIMS:
1. Electrical safety device against removing standing or hanging objects, such as pictures or the like., Characterized in that on the wall or the like. Behind or under the objects to be protected (2) contacts (3) are arranged for a quiescent current, which are conductively connected by a conductive bridge (4) or the like attached to the object, so that when the object is removed, the quiescent current is opened and a signal is thereby triggered.
