Abstract

The direction indicator uses separate flashing direction indicator lamps (RV, RH, LV, LH) using yellow LED's, controlled by a switch (S) attached to the handlebars of the bicycle and supplied from a storage battery which is recharged via a dynamo (NDYN) attached to a wheel hub, under control of a window discriminator (FD). The flashing frequency for the direction indicator lamps is provided by an electronic clock source, with different flashing frequencies used for the left and right indications.

Description

Die Erfindung betrifft eine elektrische Anordnung zur Fahrtrichtungsanzeige bei Fahrrädern.The invention relates to an electrical arrangement for indicating the direction of travel in bicycles.

Eine Fahrtrichtungsanzeige für Fahrräder ist durch die DE 297 01 326 U1 bekannt. Die bekannte Fahrtrichtungsanzeige weist Leuchtdioden auf, die jeweils mit gleicher Blinkfrequenz von 5 Hz ansteuerbar sind.A direction indicator for bicycles is known from DE 297 01 326 U1. The known direction indicator has light-emitting diodes, each with the same flashing frequency can be controlled from 5 Hz.

Der Radfahrer hat nach der Straßenverkehrsordnung jeden Fahrtrichtungswechsel durch Handzeichen anzuzeigen oder zu signalisieren. Dadurch tritt notwendigerweise eine Ver­ änderung der Schwerpunktlage des Systems Fahrer-Rad ein. Eine Instabilität des Systems ist die unvermeidliche Folge dieser Methode. Das Loslassen des Lenkers führt zu einer weiteren Destabilisierung des Systems und zu einer Verunsicherung des Fahrers. Kleine Hindernisse auf der Fahrbahn, die überrollt werden oder denen der Fahrer auszuweichen versucht, können sogar zum Sturz führen. Nachts kann eine Signalisierung des Fahrtrichtungswechsels durch den Fahrer mit Handzeichen vom nachfolgenden Verkehrtsteilnehmer u. U. nicht rechtzeitig erkannt werden. Es besteht dann erhöhte Unfallgefahr.The cyclist has to go through every change of direction according to the traffic regulations Show or signal hand signals. As a result, ver Change the center of gravity of the driver-bike system. There is an instability of the system the inevitable consequence of this method. Releasing the handlebar leads to another System destabilization and driver insecurity. Small obstacles on the road that is being rolled over or that the driver is trying to avoid even lead to a fall. At night, the direction change can be signaled by the driver with hand signals from the following road user u. May not be in time be recognized. There is then an increased risk of accidents.

Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte elektrische Anordnung zur Fahrtrichtungsanzeige bei Fahrrädern zu schaffen.The invention has for its object to provide an improved electrical arrangement To create a direction indicator for bicycles.

Gelöst wird diese Aufgabe durch die Merkmale des Patentanspruchs.This object is achieved by the features of the patent claim.

Die verwendete Blinkeinrichtung ist am Tag mindestens 50 Meter und nachts bis zu 500 Meter weit gut sichtbar.The flashing device used is at least 50 meters during the day and up to 500 meters at night widely visible.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend beschrieben.An embodiment of the invention is described below.

Die erfindungsgemässe Anordnung (Bild 1) weist einen Nabendynamo auf, der über einen Fensterdiskriminator FD (Spannungsintervall 4,7 V-5,5 V) den Akku bei Bedarf nachlädt. Die entscheidende Neuerung besteht in der Verwendung von gelben (= 590 nm) LED, die einen außergewöhnlich hohen Wirkungsgrad (10000 mcd) aufweisen. Bei einer Spannung von 5 V fließt in dem aus je 6 LED bestehenden Blinker (Bild 2) ein Strom von nur ca. 100 mA. Dies bedeutet im Vergleich zu einem Glühlämpchenblinker mit 10 W (teilweise sind bis zu 21 W im Einsatz) ein Leistungsverhältnis von 0,5 W : 10 W = 1 : 20. Es ist also nur 5% der bisher nötigen Energie für den gleichen Effekt einzusetzen. Das Gewicht des Prototyps des Richtungsanzeigers beträgt mit 4 Blinkern ohne Nabendynamo ca. 400 g.The inventive arrangement (Figure 1) comprises a hub dynamo, which recharges the battery as required via a window discriminator FD (V voltage interval 4, 7-5.5 V). The decisive innovation is the use of yellow (= 590 nm) LEDs, which have an extraordinarily high efficiency (10000 mcd). At a voltage of 5 V, a current of only approx. 100 mA flows in the turn signals, each consisting of 6 LEDs ( Figure 2). This means a power ratio of 0.5 W: 10 W = 1: 20 compared to a 10 W incandescent lamp (sometimes up to 21 W are used). It is therefore only 5% of the energy previously required for the same effect . The weight of the prototype of the direction indicator with 4 indicators without hub dynamo is approx. 400 g.

Während des Blinkbetriebes entlädt sich der Akku. Seine Spannung wird ständig von dem Fensterdiskriminator FD nach Bild 3 in der Zentraleinheit überwacht. Ist die Spannung unter 4,7 V abgefallen, wird automatisch der Dynamo zum Laden des Akkus eingeschaltet, bis dieser wieder eine Spannung von 5,5 V erreicht hat. Dann wird die Verbindung zum Dynamo unterbrochen bis die Akkuspannung wieder auf 4,7 V abgefallen ist usw..The battery discharges during blinking. Its voltage is constantly monitored by the window discriminator FD in the central unit according to Figure 3. If the voltage has dropped below 4.7 V, the dynamo for charging the battery is automatically switched on until it reaches a voltage of 5.5 V. Then the connection to the dynamo is interrupted until the battery voltage has dropped to 4.7 V, etc.

Um die bei einem Blinkvorgang aus dem Akku entnommene Energie wieder nachzuladen, ist etwa die Hälfte der aufgewendeten Blinkzeit als Betriebszeit des Dynamos erforderlich. Die Schaltung der gesamten Anlage ist aus Bild 1 ersichtlich. In der Zentraleinheit, die am Fahrradrahmen befestigt wird, befindet sich der Akku und die Elektronik. Die Taktgeber TL TR sind entsprechend Bild 2 aufgebaut. Abbiegen nach links soll wegen der besonderen Gefährdung mit der doppelten Frequenz gegenüber Rechtsabbiegen signalisiert werden. Wie von Motorrädern bekannt, wird auch hier durch Betätigung eines am Lenker angebrachten Schalters S der beabsichtigte Richtungswechsel signalisiert.In order to recharge the energy drawn from the battery during a flashing process, about half of the flashing time spent is required as the operating time of the dynamo. The circuit of the entire system can be seen in Figure 1. The battery and electronics are located in the central unit, which is attached to the bicycle frame. The TL TR clocks are constructed according to Figure 2. Turning to the left should be signaled against the right turn because of the particular risk with the double frequency. As is known from motorcycles, the intended change of direction is also signaled here by actuating a switch S attached to the handlebar.
