Description

Sicherheitsvorrichtung für Kraftfahrzeuge Ausweislich der Unfallstatistik sind zahlreiche Unfälle von Kraftfahrzeugen auf das nicht rechtzeitige Erkennen von Gefahrenstellen zurückzuführen. Unaufmerksamkeit oder Ermüdung des Fahrers, unsichtiges Wetter u. dgl. sind die häufigsten Ursachen hierfür. Die Sicherheitsvorrichtung soll dem dadurch begegnen, daß der Fahrer rechtzeitig vor Erreichen von Straßen- oder Bahnkreuzungen, Langsamfahrstrecken usw. automatisch gewarnt wird.Safety device for motor vehicles as evidenced by the accident statistics are numerous accidents involving motor vehicles due to not being detected in time traced back from danger spots. Inattentiveness or fatigue of the driver, Invisible weather and the like are the most common causes for this. The safety device is intended to counter this by ensuring that the driver in good time before reaching the road or railway crossings, slow travel routes etc. is automatically warned.

Die Vorrichtung beruht auf einem Zusammenwirken von Wagen und Straße.The device is based on an interaction between the car and the road.

Unter der Karosserie des Wagens ist mit Blickrichtung nach unten auf die Fahrbahn eine Photozelle mit Optik eingebaut, in deren Stromkreis eine Alarmvorrichtung eingeschaltet ist. Der Tastpunkt auf der Straße (Schnittpunkt des Strahlenganges mit der Straße) wird von einer kleinen Glühlampe mit Optik bestrahlt. Im Stromkreis der Photozelle entstehen beim Fahren fortlaufend Schwebungen je nach der Reflexfähigkeit der Straßenoberfläche. In der Straße sind in gehörigem Abstand vor den Gefahrenstellen die Straßenoberfläche etwas überragende, schmutzfreie Querstreifen in Form etwa einer Schiene oder Röhre eingelassen, die sich in ihrer Farbe von der Straßenoberfläche stark unterscheiden und damit auf die Photozelle besonders einwirken. Ein zuverlässiges Mark für das Auslösen eines Warnsignals können diese Streifen ohne weiteres aber nicht darstellen, weil die Straßenoberfläche mit ihren ständig wechselnden Reflexen auf die Photozelle vielfach genau so einwirkt wie der Buntstreifen.Under the body of the car is facing down a photocell with optics installed in the roadway with an alarm device in its circuit is switched on. The touch point on the road (intersection of the beam path with the road) is irradiated by a small light bulb with optics. In the circuit The photocell continuously fluctuates while driving, depending on the reflex ability the road surface. In the street are at a reasonable distance from the danger spots the road surface slightly protruding, dirt-free horizontal stripes in the form of, for example a rail or tube that is different in color from the road surface differ strongly and thus have a special effect on the photocell. A reliable one Mark for triggering a warning signal, however, these strips can easily not represent because the road surface with its constantly changing reflections acts on the photocell in the same way as the colored stripe.

Ein zuverlässiges Auslösungselement für das Warnsignal bietet folgende Bauweise: a) Der auf den Tastpunkt gerichtete Lichtstrahl passiert eine farbige Glasscheibe, die in die Optik eingebaut ist. Trifft dieser farbige Lichtstrahl auf einen Querstreifen, der in der Komplementärfarbe des Lichtstrahls ausgeführt ist, so fällt jeder Reflex fort,. weil die Komplementärfarben einander auslöschen. Der hierdurch erzielte Minimumstromstoß oder Ruhestrom der Photozelle betätigt das entsprechend eingestellte Alarmsignal.A reliable trigger element for the warning signal offers the following Construction: a) The light beam directed at the touch point passes a colored one Glass pane built into the optics. If this colored ray of light hits a Horizontal stripes that are in the complementary color of the light beam is carried out, then every reflex disappears. because the complementary colors are each other wipe out. The resulting minimum current surge or quiescent current of the photocell activates the corresponding set alarm signal.

b) Die Farbe des Streifens reflektiert einen weißen Lichtstrahl im wesentlichen in der jeweiligen Streifenfarbe. Wird vor der Optik der Photozelle eine Glasscheibe in der Komplementärfarbe des Streifens montiert, wird in gleicher Weise wie unter a) der Reflexstrahl vor Erreichen der Photozelle gelöscht und das auf Auslösung durch einen Minimumstromstoß eingestellte Alarmsignal betätigt.b) The color of the stripe reflects a white light beam in the essentially in the respective stripe color. Is placed in front of the optics of the photocell a pane of glass in the complementary color of the strip is mounted in the same As under a) the reflex beam is deleted before reaching the photocell and that Alarm signal set to be triggered by a minimum current surge actuated.

Es kann angenommen werden, daß die Zahl der Unfälle durch Nichtbeachtung wichtiger Verkehrszeichen bei automatischer Warnung wesentlich zurückgehen wird.It can be assumed that the number of accidents due to neglect important traffic signs with automatic warning will decrease significantly.

Außer im normalen Straßenverkehr zur Ergänzung der Verkehrszeichen kann die Sicherheitsvorrichtung auch in anderen Fällen gute Dienste leisten: Das Überfahren von Verkehrsinseln kann durch Anlage entsprechender Streifen verhütet werden. In der Längsrichtung auf der Außenseite der Autobahn angebrachte Streifen können dem Abgleiten der Wagen ermüdeter Fahrer entgegenwirken. Da immer wieder auf der Autobahn zur Reparatur stilliegende Wagen trotz Beleuchtung angefahren werden, schützen sich die Fahrer des stehenden Wagens zweckmäßig hiergegen, indem sie im Abstand der Bremsstrecke vor und hinter dem Wagen Bänder in der Streifenfarbe quer über die Fahrbahn legen.Except in normal road traffic to supplement the traffic signs the safety device can also serve well in other cases: Driving over traffic islands can be prevented by creating appropriate strips will. Strips applied lengthways on the outside of the motorway can counteract the sliding of the car of tired drivers. There again and again Cars that have been idle for repairs on the autobahn are hit despite lighting, The drivers of the stationary car protect themselves against this by using the Distance of the braking distance in front of and behind the car Stripes in the color of the stripes across lay across the roadway.

PATENTANSPRUCH: Sicherheitsvorrichtung für Kraftfahrzeuge, dadurch gekennzeichnet, daß unter dem Kraftfahrzeug eine Photozelle mit Optik, nach unten auf die Fahrbalvi gerichtet, als Empfänger sowie eine gegen den Empfänger zweckmäßig abgeschirmte Lichtquelle als Sender angebracht, ferner in der Straße vor einem Gefahrenpunkt ein farbiger Querstreifen vorgesehen ist, wobei entweder im Strahlengang des Senders oder Empfängers ein Farbfilter in der Komplementärfarbe der Streifenfarbe eingeschaltet ist. Claim: Safety device for motor vehicles, characterized in that under the motor vehicle a photocell with optics, directed downwards on the Fahrbalvi, mounted as a receiver and a light source appropriately shielded from the receiver as a transmitter, and a colored horizontal stripe is provided in the street in front of a danger point is, with a color filter in the complementary color of the stripe color is switched on either in the beam path of the transmitter or receiver.
