Description
Gegenstand der vorliegenden Erfindung ist eine Signalvorrichtung für Fahrzeuge, insbesondere Kraftfahrzeuge mit einem am Hinterende des Fahrzeuges angebrachten Schallempfänger, der die aufgenommenen Signale, nötigenfalls unter Zwischenschaltung eines Verstärkers, an den Führersitz weitergibt. Das Neue gemäß der Erfindung besteht darin, daß die Signale nur bei einer gewissen StärkeThe present invention relates to a signal device for vehicles, in particular Motor vehicles with a sound receiver attached to the rear end of the vehicle, which forwards the recorded signals, if necessary with the interposition of an amplifier, to the driver's seat. That New according to the invention is that the signals only at a certain strength
ίο durch einen Schallsender und eine Glimmlampe, die hintereinandergeschaltet sind, hörbar und sichtbar werden. Dabei ist der Schallempfänger zweckmäßig stoßfrei angeordnet, z.B. durch Polsterung in Gummischwamm oder Watte.ίο by a sound transmitter and a glow lamp, that are connected in series, become audible and visible. The sound receiver is expediently arranged without bumps, e.g. by padding in a rubber sponge or cotton wool.
Die Zeichnung zeigt schematisch und in Aufsicht ein Ausführungsbeispiel der Vorrichtung für einen geschlossenen Kraftwagen. Am hinteren Ende des Kraftwagens ist ein Schallempfänger α eingebaut, von dem die aufgefangenen Lautsignale über einen Verstärker δ zum Führersitz in Form von elektrischer Energie zu einem Lautsprecher C und einer Glimmlampe d weitergeleitet werden. Durch diese hörbare und sichtbare Signalgebung wird der Wagenführer in sicherer Weise auf die Signale überholender Fahrzeuge aufmerksam gemacht. Um nun im Lautsprecher c nicht dauernd auch die schwächeren Nebengeräusche, z.B. des eigenen Wagens, zu haben, wird die Glimmlampe ei mit dem Lautsprecher c hintereinandergeschaltet und dadurch nach den bekannten Eigenschaften der Glimmlampe ein gewisser Schwellenwert der Empfindlichkeit erzielt. Der Lautsprecher c spricht daher erst bei einer bestimmten Signalstärke an, gleichzeitig mit ihm die Glimmlampe.The drawing shows schematically and in plan view an embodiment of the device for a closed motor vehicle. A sound receiver α is installed at the rear end of the motor vehicle, from which the intercepted sound signals are passed on via an amplifier δ to the driver’s seat in the form of electrical energy to a loudspeaker C and a glow lamp d . Through this audible and visible signaling, the driver is made aware of the signals of overtaking vehicles in a safe manner. In order not to have the weaker background noises in the loudspeaker c all the time, eg from one's own car, the glow lamp ei is connected in series with the loudspeaker c and a certain threshold value of sensitivity is thereby achieved according to the known properties of the glow lamp. The loudspeaker c therefore only responds at a certain signal strength, at the same time as the glow lamp.
Der zu übermittelnde Schall wird von dem Empfänger α aufgenommen und in elektrische Energie verwandelt, die im Relais b verstärkt wird. Im Ausgangskreis des' Verstärkers b ist die Glimmlampe d mit dem Schallsender oder Lautsprechern hintereinandergeschaltet.The sound to be transmitted is picked up by the receiver α and converted into electrical energy, which is amplified in the relay b. In the output circuit of the amplifier b , the glow lamp d is connected in series with the sound transmitter or loudspeakers.
Dei· Schallempfänger ist zum Schutz gegen die beim Fahren auftretenden Stöße mit einer Polsterung aus Gununischwamm oder Watte umgeben.The sound receiver is for protection against the bumps that occur while driving with a padding made of Gununi sponge or cotton wool surround.
Die Einzelheiten der Ausführung sind nicht an das vorstehende Beispiel gebunden.The details of the implementation are not restricted to the above example.
