Description
Die Erfindung betrifft eine Blink-Bremslichtanlage für Kraftfahrzeuge, durch die mittels eines Verzögerungsschalters eine Strornunterbrechung im Bremslicht-Stromkreis beim rhythmischen Bremsen verhindert werden soll. Da nämlich häufig das Blinklicht zur Anzeige eines Fahrtrichtungswechsels und das Bremslicht als Stopsignal für nachfolgende Fahrzeuge in einer gemeinsamen Leuchte untergebracht sind, können sonst leicht Irrtümer eintreten. Wird nämlich zur allmählichen Abbremsung der Fahrt die Bremse in kurzen Intervallen betätigt, so entstehen beim Stoplicht durch entsprechendes Betätigen des Bremslichtschalters kurzzeitige Lichtblitze, die sich von dem Blinklicht für den Fahrtrichtungswechsel kaum unterscheiden lassen.The invention relates to a flashing brake light system for motor vehicles, through which a current interruption in the brake light circuit by means of a delay switch should be prevented during rhythmic braking. Because often the flashing light to indicate a change of direction and the brake light as a stop signal for following vehicles are housed in a common luminaire, errors can otherwise easily occur. Namely will to gradually slow down the journey, apply the brake at short intervals, which is how the stop light occurs by appropriately pressing the brake light switch, brief flashes of light that differ from the The flashing light for changing the direction of travel can hardly be distinguished.
Es ist bekannt, zur Verhinderung des Mitblinkens der Schlußlichter bei rhythmischer Betätigung eines Lichtsignalschalters die Schlußlichter über einen Bimetallschalter ein- oder auszuschalten, dessen Heizstromspule so im Lichtsignal-Stromkreis liegt, daß die thermisch verzögerte Ein- oder Ausschaltzeit dieses Bimetallschalters den Schaltrhythmus des Signalschalters überbrückt. Bei der bekannten Anordnung ist also Voraussetzung, daß der Schaltrhythmus kurz genug ist, um das Ansprechen des Bimetallschalters zu verhindern.It is known to prevent the taillights from flashing when a rhythmic actuation occurs Light signal switch the tail lights via a bimetal switch on or off, the heating current coil is so in the light signal circuit that the thermally delayed switch-on or switch-off time of this bimetal switch the switching rhythm of the signal switch bridged. In the known arrangement it is therefore a prerequisite that the switching rhythm is short is enough to prevent the bimetal switch from responding.
Beim Bremsen ist der Schaltrhythmus von den Fahrbedingungen abhängig, und es ist daher erforderlich, daß auch längere Ausschaltperioden vom Hilfsschalter überbrückt werden, um ein Flackern des Bremslichtes zu vermeiden.When braking, the switching rhythm depends on the driving conditions and it is therefore necessary that longer switch-off periods are bridged by the auxiliary switch to prevent the To avoid brake lights.
Gemäß der Erfindung wird eine Überbrückung auch längerer Ausschaltperioden dadurch erreicht, daß ein den Bremslampenkreis sofort einschaltender Zeitschalter vorgesehen ist, dessen Abschaltzeit dieBrems-Intervalle überbrückt. Entweder kann der Bremslichtschalter selbst mit einer verzögernden Ausschalteinrichtung ausgerüstet sein, oder es kann ein besonderer Schalter vorgesehen werden, der nach Betätigen des Bremslichtschalters ein verzögertes Ausschalten des Bremslicht-Stromkreises bewirkt.According to the invention, a bridging of longer switch-off periods is achieved in that a time switch is provided to switch on the brake lamp circuit immediately, the switch-off time of which the braking intervals bridged. Either the brake light switch itself can be equipped with a delayed switch-off device be equipped, or a special switch can be provided, which after pressing the Brake light switch causes a delay in switching off the brake light circuit.
Der Verzögerungsschalter und zugleich Einschalter für das Bremslicht kann ein hydraulisch, insbesondere vom Bremsöldruck betätigter Schalter sein, dessen elektrische Kontakte in einer abgeschlossenen Kammer liegen. Die eine Wand der Kontaktkammer ist membranartig ausgebildet und wird vom Öldruck beeinflußt, wobei sie den Schalter schließt, während das öffnen durch eine verzögerte Rückströmung des Öls aus einer der Schalterkammermembran vorgelagerten Öldruckkammer bewirkt wird.The delay switch and at the same time the switch for the brake light can be hydraulic, in particular be operated by the brake oil pressure switch, its electrical contacts in a closed chamber lie. One wall of the contact chamber is designed like a membrane and is influenced by the oil pressure, closing the switch while opening it by delaying the return flow of the oil is effected from an oil pressure chamber upstream of the switch chamber membrane.
Bei Verwendung eines besonderen elektrischen Verzögerungsschalters, der in Reihe mit dem eigentlichen Bremslichtschalter liegt, ist es erforderlich, daß dieser Blink-Bremslichtanlage für KraftfahrzeugeWhen using a special electrical delay switch, which is in series with the actual brake light switch, it is necessary that this Flashing brake light system for motor vehicles

Schalter normalerweise eingeschaltet ist und erst nach Betätigen des Bremslichtschalters über eine unter Bereitschaftsstrom stehende, verzögert abschaltende Einrichtung geöffnet wird, wobei der Bereitschaftsstromkreis durch den Bremslichtschalter gleichzeitig eingeschaltet werden kann.Switch is normally on and only after pressing the brake light switch via a standby current standing, delayed disconnection device is opened, whereby the standby circuit can be switched on at the same time by the brake light switch.
Der Bereitschaftsstrom für einen derartigen Schalter kann auch vom Blinklichtgeber ein- oder ausgeschaltet werden, so daß das Ansprechen der Verzögerungseinrichtung nur bei gleichzeitiger Betätigung des Blinklichtes möglich ist.The standby current for such a switch can also be switched on or off by the flasher light transmitter so that the response of the delay device only when the Flashing light is possible.
