Description
Lichtsignalampeln mit blinkendem Signallicht sind an sich bekannt. Sie haben gegenüber den gewöhnlichen Buntlichtampeln und besonders gegenüber den Uhrzeiger amp ein den Vorteil guter Sichtbarkeit auf weite Entfernung. Dieser Vorteil kann aber praktisch nicht ausgewertet werden, wenn das Signal keinen Hinweis gibt, wann der Signalwechsel erfolgt, so daß die Kraftfahraeugführer, die zwar aus größerer Entfernung das blinkende Signal erkennen;, ihre Fahrgeschwindigkeit nicht entsprechend einrichten können, um am Kreuzungspunkt keine Verkehrsstockung zu verursachen.Traffic lights with a flashing signal light are known per se. You have opposite the usual colored traffic lights and especially opposite the clock hands amp the advantage of good visibility from a long distance. This benefit can be practical though cannot be evaluated if the signal does not indicate when the signal change occurs takes place, so that the Kraftfahraeugführer, although from a greater distance the flashing Detect signal; unable to set up their driving speed accordingly in order to am Crossing point not to cause traffic congestion.
Die Uhrzeigerampel läßt zwar die Zeit bis zum Wechsel des Signals ermessen, besitzt aber den Nachteil, daß sowohl die Signalfarben wie auch besonders die Geschwindigkeit des Zeigers nur aus nächster Nähe gut beobachtet werden können. Sie nimmt daher die Aufmerksamkeit des Fahrers zu sehr für sich in Anspruch und lenkt ihn von der Beachtung des Allgemeinverkehrs zu sehr ab.The clock hand light lets the time measure until the signal changes, but has the disadvantage that both the signal colors and especially the speed of the pointer can only be observed at close range. It therefore takes the driver's attention too much of a claim to himself and distracts him from paying attention to general traffic too much.
Das Verfahren gemäß der Erfindung vermeidet die bei der bisher bekannten Signalgebung auftretenden Nachteile. Es besteht darin, daß die Blinkfolge vom Beginn bis zum Ende jeder Signalgabe gleichmäßig zu- oder abnimmt. Aus der Geschwindigkeit, mit der das Blinken vor sich geht, kann der Beobachter leicht ermessen, wie weit die Signalgabe sich ihrem Ende genähert hat. Durch das blinkende Signallicht sind gute Sichtbarkeit auf weite Entfernung sowie unbedingtes Auffallen bei jeder Witterung und bei größtem Verkehr gewährleistet.The method according to the invention avoids the signaling known hitherto occurring disadvantages. It consists in the flashing sequence increasing evenly from the beginning to the end of each signaling. or decreases. The observer can tell from the speed at which the blinking occurs easily measure how close the signaling has come to an end. By the flashing signal light are good visibility at long distance as well as essential It is guaranteed to attract attention in all weathers and in heavy traffic.
Die wechselnde Blinkschnelligkeit kann durch eine Schaltwalze, die die Stromunterbrechungen steuert oder eine ähnliche bekannte Einrichtung hergestellt werden.The changing blinking speed can be controlled by a shift drum that interrupts the power controls or a similar known device can be manufactured.
In der Abbildung ist ein Beispiel für die Herstellung steigender Blinkschnelligkeit dargestellt. The illustration shows an example of the creation of increasing blinking speed.
Ein Schaltrad ff besitzt Zähne b, die eine in d gelagerte Quecksilberröhre c kippen und damit den Stromkreis für die Signallampen kurz unterbrechen. Die Zähne b sind in gleichmäßig sich verringerndem Abstand am Umfang des Schaltrades α angeordnet, so daß die Blinkfolge bei gleichbleibender Drehzahl des Schaltrades ß gleichmäßig gesteigert wird.A ratchet wheel ff has teeth b which tilt a mercury tube c stored in d and thus briefly interrupt the circuit for the signal lamps. The teeth b are arranged at a uniformly decreasing distance on the circumference of the indexing wheel α , so that the flashing sequence is increased evenly while the speed of the indexing wheel remains constant.
