Description

Es ist bekannt, Kraftwagen dadurch gegen Diebstahl und Straßenraub zu sichern, daß eine Einrichtung an das Fahrzeug gebaut wird, die bei einer Erschütterung des Fahrzeuges einen Alarm auslöst. Diese Einrichtung ist durchaus zuverlässig; denn auch beim öffnen einer Persenning oder Herabnehmen eines Paketes vom Fahrzeug sind Erschütterungen unvermeidbar. Diese Einrichtung hat aber den Nachteil, daß der Alarm auch ausgelöst wird, wenn eine Erschütterung aus harmlosen Gründen, z. B. Anstoßen durch Kinder, hervorgerufen wird. Um aber zu erreichen, daß die Sicherheitseinrichtung nur dann ausgelöst wird, wenn tatsächlich ein Unbefugter die Persenning öffnet, wird erfindungsgemäß ein akustisches oder optisches Signal beim öffnen einer Schnalle ausgelöst, so daß Vorübergehende oder der Besitzer selbst auf den Diebstahl aufmerksam gemacht werden.It is known to protect motor vehicles against theft and road robbery to ensure that a device is built on the vehicle, which in the event of a shock of the vehicle triggers an alarm. This facility is perfectly reliable; because even when opening a tarpaulin or removing a package from the vehicle vibrations are unavoidable. This device has the disadvantage that the alarm is also triggered if a shock occurs for harmless reasons, e.g. B. bumping into children. But in order to achieve that the safety device is only triggered if an unauthorized person actually opens the tarpaulin, according to the invention, an acoustic or optical signal when opening a buckle triggered so that passers-by or the owner himself become aware of the theft be made.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt und zeigt Abb. r die Verschlußschnalle einer Persenning in Seitenansicht, Abb. 2 die Draufsicht zu Abb. r und Alb. 3 das Schaltschema der Alarmanlage.An exemplary embodiment of the invention is shown in the drawing and Fig. r shows the locking buckle of a tarpaulin in side view, Fig. 2 the top view to Fig. r and Alb. 3 the circuit diagram of the alarm system.

Die neue Einrichtung besteht aus einer elektrisch betriebenen Signalvorrichtung, deren einer Stromkreis beim öffnen der Schnalle Sch, in die ein besonders feinmaschiges Drahtgewebe D aus Kupfer, Messing oder ähnlichen Metallen hineingearbeitet ist, geschlossen wird. Diese -Schnallen können in beliebiger Zahl angebracht werden und werden sämtlich hintereinandergeschaltet, so daß beim öffnen irgendeiner dieser Schnallen der Stromkreis r unterbrochen wird und über das Relais R die Kontakte r mechanisch geschlossen werden. Hierdurch wird der Stromkreis 2 geschlossen und eine elektrische Verbindung zwischen der Batterie B und dein Signalgeber H, z. B. einem Horn, hergestellt. Der Signalgeber H ist so lange in Tätigkeit, wie die Schnalle geöffnet ist oder die Anlage eingeschaltet bleibt. Die ganze Anlage kann durch den Schalter S aus- oder eingeschaltet werden.The new device consists of an electrically operated signaling device, one circuit of which is closed when the buckle Sch, in which a particularly fine-meshed wire mesh D made of copper, brass or similar metals is worked, is opened. Any number of these buckles can be attached and are all connected in series, so that when any one of these buckles is opened, the circuit r is interrupted and the contacts r are mechanically closed via the relay R. As a result, the circuit 2 is closed and an electrical connection between the battery B and your signal generator H, z. B. a horn. The signal transmitter H is active as long as the buckle is open or the system remains switched on. The entire system can be switched on or off using switch S.
