Abstract

The invention relates to a switching arrangement for security devices, for example goods security devices. It is used for signalling unauthorised removal of goods. For this purpose, the goods are connected to a transmitter which can operate the goods security device. It is intended to create a transmitter (switch) which can be mounted on an item of goods and cannot easily be overcome, that is to say cannot be removed from the item of goods, without a signal being produced. For this purpose, the switching arrangement contains two plungers (8) which are mounted on a Z-shaped operating element (6). <IMAGE>

Description

Die Erfindung betrifft eine Schaltvorrichtung für Sicherungseinrichtungen.The invention relates to a switching device for safety devices.

Bei den Sicherungseinrichtungen kann es sich beispielsweise um Warensicherungseinrichtungen handeln. Sie werden dazu verwendet, um feilgehaltene Waren, in der Regel Elektrogeräte, hochwertige Bekleidung oder dgl., gegen das mißbräuchliche Entfernen zu schützen. Zu diesem Zweck sind die Waren mit einem Geber versehen, welcher mit der Warensicherungseinrichtung verbunden ist. Wird nun bei einer solchen Einrichtung die Verbindung zwischen dem Geber und Warensicherungseinrichtung unterbrochen oder der Geber von der Ware entfernt, dann soll die Warensicherungseinrichtung ansprechen, d.h. ein optisches und/oder akustisches Signal geben. Bei dem Geber kann es sich beispielsweise um einen elektrischen Schalter handeln, der in vorgesehenem Betriebszustand geschlossen ist. Wird die Leitung zwischen Geber und Warensicherungseinrichtung unterbrochen oder der Geber von der Ware entfernt, dann öffnet der Schalter und löst Alarm aus.The security devices can, for example, be goods security devices. They are used to protect goods, usually electrical appliances, high-quality clothing or the like, against improper removal. For this purpose, the goods are provided with a donor, which is connected to the goods security device. If the connection between the giver and goods security device is interrupted or the giver is removed from the goods in such a device, the goods security device should respond, ie give an optical and / or acoustic signal. The transmitter can be, for example, an electrical switch that is closed in the intended operating state. If the line between the transmitter and the goods security device is interrupted or the transmitter is removed from the goods, the switch opens and triggers an alarm.

Das der Erfindung zugrunde liegende technische Problem besteht darin, einen einfach aufgebauten Geber zu schaffen, welcher in einfacher Weise an einer zu sichernden Ware befestigt werden kann und der Manipulationen ausschließt.The technical problem on which the invention is based is to create a simply constructed encoder which can be attached to a product to be secured in a simple manner and which prevents manipulation.

Dieses technische Problem ist erfindungsgemäß durch eine Schaltvorrichtung mit folgenden Merkmalen gelöst:

  • a) ein flaches, mit einem Deckel verschließbares Gehäuse, auf dessen Gehäuseboden ein Tastenschalter befestigt ist,
  • b) einen auf der Rückseite des Deckels angeordneten Betätiger, welcher aus einem flachen, die Taste des Tastenschalters berührenden Band und einem an dessen Ende vorhandenen, durch den Deckel hindurchragenden Stößel besteht,
  • c) einer auf der Außenfläche des Deckels vorgesehenen Klebeschicht.
This technical problem is solved according to the invention by a switching device with the following features:
  • a) a flat housing which can be closed with a lid and on the housing base of which a key switch is fastened,
  • b) an actuator arranged on the back of the cover, which consists of a flat band touching the key of the key switch and a plunger which is present at the end and protrudes through the cover,
  • c) an adhesive layer provided on the outer surface of the lid.

Eine solche Vorrichtung ist einfach aufgebaut und daher kostengünstig herstellbar. Dennoch ist sie in einfacher Weise an der Ware anzubringen und erfüllt seinen Zweck zufriedenstellend.Such a device is simple and therefore inexpensive to manufacture. Nevertheless, it can be attached to the goods in a simple manner and fulfills its purpose satisfactorily.

Vorteilhafte Einzelheiten der Erfindung sind in den Ansprüchen 2 bis 7 enthalten. Sie ist nachstehend anhand eines in den Figuren 1 bis 4 gezeigten Ausführungsbeispieles erläutert. Es zeigen:

Wie aus Fig. 2 zu erkennen, ist im Zentrum des Gehäuses 1 der Tastenschalter 2 angeordnet. Der Tastenschalter 2 ist, wie anhand von Fig. 3 besser zu erkennen ist, auf einer Platte 3 befestigt; wenn es sich bei der Platte 3 um eine Leiterpaltte handelt, sind die Anschlüsse des Tastenschalters 2 mit den Leiterbahnen auf der Leiterplatte verlötet. Der Boden des Gehäuses 1 ist einstückig mit rohrförmigen Buchsen 4 versehen. Die Platte 3 weist an den den Buchsen 4 entsprechenden Stellen Öffnungen auf, so daß sie über die Buchsen 4 geschoben werden kann.As can be seen from FIG. 2, the key switch 2 is arranged in the center of the housing 1. The key switch 2 is, as can be seen more clearly from FIG. 3, attached to a plate 3; if the plate 3 is a conductor gap, the connections of the key switch 2 are soldered to the conductor tracks on the circuit board. The bottom of the housing 1 is provided in one piece with tubular bushings 4. The plate 3 has openings at the points corresponding to the sockets 4, so that it can be pushed over the sockets 4.

In Fig. 2 ist die Innenseite des Deckels 5 mit dem in den Deckel eingelegten Betätiger 6 zu erkennen. Auch die Innenseite des Deckels 5 ist mit rohrförmigen Buchsen 7 versehen, welche derart dimensioniert sind - wie aus Fig. 3 ersichtlich -, daß sie über die Buchsen 4 im Gehäuse 1 passen.2 shows the inside of the cover 5 with the actuator 6 inserted in the cover. The inside of the cover 5 is also provided with tubular bushings 7, which are dimensioned such - as can be seen from FIG. 3 - that they fit over the bushings 4 in the housing 1.

Aus Fig. 4 wird die Gestalt des Betätigers 6 deutlich. Er besteht aus einem Z-förmigen Band und ist an den Enden mit den Stößeln 8 versehen. Das Zentrum des Betätigers 6 ist kreisförmig vergrößert; es liegt bei der fertigen Schaltvorrichtung über der Taste 10 des Tastenschalters.The shape of the actuator 6 is clear from FIG. It consists of a Z-shaped band and is provided with plungers 8 at the ends. The center of the actuator 6 is enlarged in a circle; it is in the finished switching device above the key 10 of the key switch.

Fig. 3 verdeutlicht den Aufbau der fertigen Schaltvorrichtung. Auf der Außenseite des Deckels 5 ist noch eine Platte 11 mit einer Kleberschicht 12 vorgesehen. Deckel 5 und Platte 11 sind mittels Schrauben 13 am Gehäuse 1 befestigt, welche in die mit Innengewinde versehene Buchsen 4 eingeschraubt sind.Fig. 3 illustrates the structure of the finished switching device. A plate 11 with an adhesive layer 12 is also provided on the outside of the cover 5. Cover 5 and plate 11 are fastened to the housing 1 by means of screws 13, which are screwed into the internally threaded bushings 4.

Wenn - wie in Fig. 3 dargestellt - die Schaltvorrichtung nicht auf einem Gegenstand befestigt ist, dann ragen die Stößel 8 über die Außenkante des Deckels 5 hinaus. Dann sind die elektrischen Kontakte des Tastenschalters 2 geöffnet. Der Betätiger 6 kann auch so ausgebildet sein, daß er mehr als zwei Stößel 8 besitzt.If - as shown in Fig. 3 - the switching device is not attached to an object, then the plunger 8 protrude beyond the outer edge of the cover 5. Then the electrical contacts of the key switch 2 are opened. The actuator 6 can also be designed so that it has more than two plungers 8.
