Description

Warn- und Signalvorrichtung für Fahrzeuge Es sind schon Vorschläge gemacht, einen vorauffahrenden Kraftwagen von einem überholenden Wagen aus durch akustische oder sonstige bekannte physikalische Mittel zu warnen unter Anwendung besonderer Einrichtungen für die Wahrnehmbarmachung des Signals auf dem vorauffahrenden Kraftwagen. Insbesondere bei Lastwagen besteht der Übelstand, daB der Führer durch die Geräusche des Wagens das normale Signal des überholenden Wagens gar nicht hört. Die vorgeschriebenen Rückspiegel erfüllen ihren Zweck nur, wenn sie vom Führer beachtet werden und ryenn sie in Ordnung sind, was meistens nicht der Fall ist. Deshalb hatte man Vorschläge gemacht, das normale Hupensignal durch Anwendung von Verstärkereinrichtungen auf dem vorauffahrenden Wagen besser wahrnehmbar zu machen.Warning and signaling device for vehicles There are already proposals made to pass a vehicle driving up ahead from an overtaking vehicle warn using acoustic or other known physical means special facilities for making the signal perceptible on the preceding one Motor vehicle. Especially with trucks there is the problem that the driver can get through the noise of the car does not hear the normal signal of the overtaking car. The prescribed rear-view mirrors only serve their purpose if they are observed by the driver will and ryenn they are fine, which is mostly not the case. Therefore had Suggestions were made for the normal horn signal by using amplifier devices to make it more noticeable on the car in front.

Durch den starken Autoverkehr ist die Anwendung von akustischen lauten Signalen zu einer Plage geworden, weshalb die vorliegende Erfindung andere Mittel vorschlägt, die einfach und betriebssicher sind.Due to the heavy traffic, acoustic noises are used Signals have become a nuisance, which is why the present invention other means suggests that are simple and reliable.

Es ist bekannt, durch Lichtstrahlen eine Selenzelle o dgl. zur Widerstandsänderung anzuregen, welche über ein Relais eine zweite Stromquelle einschalten. Wenn man die Scheinwerfer des überholenden Wagens benutzt, um eine im ersten Wagen angebrachte Selenzelle zu bestrahlen, so ist diese Einrichtung für die Praxis deshalb unbrauchbar, weil sie vom normalen Tageslicht und in der Nacht von allen anderen Lichtquellen ebenfalls erregt würde.It is known to use light rays to create a selenium cell or the like to change the resistance to stimulate, which switch on a second power source via a relay. If used the headlights of the overtaking car to detect one installed in the first car To irradiate selenium cells, this device is therefore useless in practice, because they are from normal daylight and at night from all other light sources would also be aroused.

Es wird nun vorgeschlagen, die Scheinwerferlichtstrahlen mit Unterbrechungen, etwa im Tempo eines Wechselstromweckers, auf die Selenzelle wirken zu lassen. Hierdurch ist eine eindeutige Signalgebung möglich, die noch vereinfacht werden kann, wenn die Unterbrechung der Lichtstrahlen so schnell erfolgt, daß die Widerstandsänderungen der Selenzelle in akustisch wahrnehmbarer Tonhöhe erfolgen. Die Selenzelle kann dann in einen Telephonkreis, gegebenenfalls unter Anwendung von Verstärkermittel, wie sie in der Radiotelephonie gebräuchlich sind, eingeschaltet werden.* In der Zeichnung bedeutet A den Empfängerstromkreis auf dem vorauffolgenden Wagen, B die Sendeeinrichtung auf dem überholenden Wagen. Der Scheinwerfer i ist in dem normalen Stromkreis der Hupe 2 eingeschaltet. Mit den Stromunterbrechungen in der Hupe 2 schwankt auch das Licht des Scheinwerfers i. Die Selbnzelle 3 liegt in dem Stromkreis dis Telephons 4, so daß die Lichtschwankungen direkt in Schallwellen umgesetzt werden. Genügt die Lautstärke nicht, so ist 'die Anwendung bekannter Verstärker, etwa einer Hochfrequenzröhre, möglich, die die Widerstandsschwankungen der Selenzelle verstärkt. Auch die Anwendung eines Vibrationsrelais im Niederfrequenzstromkreis ist möglich. Die Unterbrechungen des Sendestromkreises können auch langsamer erfolgen, so daB anstatt des Telephons 4 ein Wechselstromrelais eingeschaltet wird, welches einen zweiten Stromkreis für die Betätigung eines Signals beeinflußt. Die Lichtschwankungen des Sendescheinwerfers können auch durch Anwendung einer Blende vor der Lichtquelle hervorgerufen werden. Die Blende wird dabei durch mechanische oder elektromagnetische Mittel in Bewegung gesetzt. .It is now proposed to interrupt the headlight beams, at about the speed of an alternating current alarm clock to let the selenium cell work. Through this a clear signaling is possible, which can be simplified if the interruption of the light rays takes place so quickly that the resistance changes the selenium cell take place in acoustically perceptible pitch. The selenium cell can then in a telephone circuit, if necessary with the use of amplifying means, as they are used in radio telephony. * In the Drawing A means the receiver circuit on the preceding carriage, B the Transmitting device on the overtaking car. The headlight i is in the normal one Horn 2 circuit switched on. With the power interruptions in the horn 2 the light of the headlight also fluctuates i. The self-cell 3 is in the circuit dis telephones 4, so that the light fluctuations are converted directly into sound waves. If the volume is not sufficient, use a known amplifier, such as one High-frequency tube, possible, which increases the resistance fluctuations of the selenium cell. It is also possible to use a vibration relay in the low-frequency circuit. The interruptions in the transmission circuit can also take place more slowly, so that instead of the telephone 4, an AC relay is switched on, which one influenced second circuit for the actuation of a signal. The fluctuations in light of the transmitter headlight can also be achieved by using a screen in front of the light source be evoked. The aperture is made by mechanical or electromagnetic Means set in motion. .
