Betr.: Geschwindigkeitsanzeiger für Fahrzeuge. Re: speed indicators for vehicles.
Geschwindigkeitsanzeiger für Fahrzeuge sind in den verschiedensten Ausführungen bekannt.Speed indicators for vehicles are in the most diverse Executions known.
Sie bestehen im wesentlichen aus einem Zeigergerät, welches die jeweilige Fahrgeschwindigkeit durch Stellung des Zeigers über einer Skala anzeigt.They essentially consist of a pointing device, which indicates the respective driving speed by positioning the pointer over a scale.
Geschwindigkeitsanzeiger dieser Art sind jedoch schlecht oder garnicht geeignet, die Geschwindigkeit des Fahrzeuges von einem außerhalb des Fahrzeuges befindlichen Beobachter erkennen zu lassen.Speed indicators of this type are poorly or not at all suitable, the speed of the vehicle from to be recognized by an observer located outside the vehicle.
Bei Anbringung eines solchen Gesehwindigkeitsanzeigers an einer von außerhalb erkennbaren Stelle des Fahrzeuges müßte die Skala des Geschwindigkeitsanzeigers einen Durchmesser von 1 m oder mehr erhalten, wenn er aus größerer Entfernung abgelesen werden sollte.When attaching such a speedometer to a point of the vehicle recognizable from the outside, the scale of the speedometer should have a diameter of Maintain 1 m or more when reading from a distance.
Is ist ohne weiteres klar, daß die Verwendung eines solchen Geschwindigkeitsmessers weder rationell ist noch praktisch durchgeführt werden kann.It is immediately clear that the use of such a Speedometer is neither rational nor can be carried out in practice.
Die Bedeutung, die Geschwindigkeit eines Fahrzeuges von außen und aus größerer Entfernung erkennen zu können, dürfte ohne weiteres einleuchtend sein.The importance of being able to recognize the speed of a vehicle from outside and from a greater distance should be without further obvious.
Es ist bekannt, daß nicht nur an Bahnübergängen, sondern insbesondere auch beim Überholen von Fahrzeugen schwere tfnfälle dadurch entstanden sind, daß die Fahrzeuglenker sich über die Geschwindigkeit des anderen Fahrzeuges getäuscht hatten.It is known that not only at level crossings, but in particular Serious accidents have also occurred when overtaking vehicles because the driver of the vehicle rests on the Had misled the speed of the other vehicle.

zeuges würde deshalb in vielen Fällen Unfälle verhüten.It would therefore prevent accidents in many cases.
Bemäß dem Gegenstand der Erfindung wird deshalb eine Einrichtung vorgesehlagen, die ohne Verwendung eines üblichen Geschwindigkeitsanzeigers mit Zeiger (!Tachometer) ein einfaches Blinklicht am Bug und Heck des Fahrzeuges verwendet, um daraus ein Maß für die Geschwindigkeit zu finden. =In accordance with the subject matter of the invention is therefore a Establishment proposed without using a usual Speed indicator with pointer (! Speedometer) a simple flashing light is used at the front and rear of the vehicle, in order to find a measure for the speed from it. =
Und zwar ist die Einrichtung derart getroffen, daß das Blinklicht periodisch mit einer Frequenz aufleuchtet, die proportional mit der Fahrgeschwindigkeit zu- und abnimmt.The facility is designed in such a way that the The flashing light lights up periodically at a frequency that increases and decreases proportionally with the driving speed.
Die Frequenz des Blinkens ist dabei so gewählt, daß bei höchstmöglicher Geschwindigkeit des Fahrzeuges das Auge das Blinklicht des Lichtes gerade noch' erkennen kann, also das Blinklicht eine Freqaaerfz unter 16 Hz hat.The frequency of the flashing is chosen so that the eye can see at the highest possible speed of the vehicle the flashing light of the light can just 'recognize', so the flashing light has a frequency below 16 Hz.
Schon nach kürzerer Zeit werden sich die Fahrzeuglenker oder auch die Fußgänger aus der Häufigkeit des Auf- und Abblinkens ein Maß für die Geschwindigkeit des Fahrzeuges machen können.After a short period of time, drivers or even pedestrians will be aware of the frequency of flashing and flashing can make a measure of the speed of the vehicle.
Die Frequenz des Auf- und Abblinkens wird dabei von einem Unterbrecher bewerkstelligt, der von der Fahrzeugachse gegebenenfalls über ein Rädergetriebe zur Erreichung der für das Auge erkennbaren Frequenz für das gesamte Geschwindigkeitsbereich einen elektr■» Stromkreis unterbricht und schließt.The frequency of the flashing up and down is brought about by an interrupter, the one from the vehicle axle, if necessary Via a gear train to achieve the frequency that is visible to the eye for the entire speed range interrupts and closes an electrical circuit.
In Abb. 1 und 2 ist ein solcher Unterbrecher in zwei Schnittebenen dargestellt, während Abb. 3 einen Schaltplan zeigt.In Fig. 1 and 2 such a breaker is in two sectional planes shown, while Fig. 3 shows a circuit diagram.
Von der Fahrzeugachse bzw« von einer Achse des Getriebes, welche zum Antrieb der biegsamen Welle für das Tachometer dient, wird die Welle 1 angetrieben, auf der eine Seheibe 2 exzentrisch aufgesetzt ist.From the vehicle axis or from one axis of the transmission, which drive the flexible shaft for the speedometer is used, the shaft 1 is driven, on which a Seheibe 2 is placed eccentrically.
Beim Umlauf drückt die exzentrisch aufgesetzte Scheibe 2die Kontaktfeder 3 mit dem Kontakt A- gegen eine zweite Kontaktfeder 5» die mit der Kontaktfeder 3 an dem Isolierstück 6 befestigt ist.As it rotates, the eccentrically attached disk 2 presses the contact spring 3 with the contact A- against a second contact spring 5 'which is fastened to the insulating piece 6 with the contact spring 3.
