Description

Vorrichtung an Kraftfahrzeugen zur Erweiterung des Gesichtsfeldes des Fahrzeugführers, insbesondere zum Sichtbarmachen der zur Verkehrsregelung dienenden optischen Signale Die Erfindung bezieht sich auf Vorrichtungen an Kraftfahrzeugen zur Erweiterung des Gesichtsfeldes des Fahrzeugführers, insbesondere zum Sichtbar-machen der zur Verkehrsregeleng dienenden optischen Signale unter Verwendung einer an der Windschutzscheibe befestigten Linse.Device on motor vehicles for expanding the field of vision of the vehicle driver, in particular to make those used for traffic control visible Optical signals The invention relates to devices on motor vehicles to expand the driver's field of vision, in particular to make them visible the optical signals used to regulate traffic using one of the Windshield attached lens.

Es sind bereits Vorrichtungen dieser Art bekannt, bei denen auf der Windschutzscheibe unmittelbar eine Konkavlinse befestigt ist, die ein verkleinertes Bild der Umgebung zeigt. Diese bekannten Einrichtungen haben den Nachteil, daß ihre Wirkung- bei hellem Tageslicht oder bei seitlicher Beleuchtung oder unter der Wirkung nahegelegener Lampen mehr oder weniger aufgehoben wird. Außerdem. ist hierbei das deutliche Sehen von dem. Ab.stande des Auges von der Konkavlinse abhängig.There are already devices of this type known in which on the Windshield directly a concave lens is attached, which is a scaled down Picture shows the area. These known devices have the disadvantage that their Effect - in bright daylight or with side lighting or under the effect nearby lamps is more or less canceled. Aside from that. here is that clear vision of that. Distance of the eye from the concave lens depends.

Die Erfindung bezweckt, diese Nachteile der bekannten Einrichtungen dadurch. zu vermeiden, daß mit der Linse durch ein lichtundurchlässiges Gehäuse eine 'Mattscheibe verbunden wird. Es wird dadurch erreicht, daß auf der Mattscheibe, die zweckmäßig noch von einem Lichts-chinn umgeben ist, unbeeinflußt vom. Tageslicht oder von in der Nähe befindlichen Lichtquellen, das zu beobachtende optische Signal deutlich erkennbar ist. Auf der Mattscheibe ist hierbei nicht nur dieses zu beobachtende optische Signal, sondern auch dessen weitere Umgebung deutlich erkennbar. Es ist sogarmöglich, das Gesichtsfeld auf der Mattscheibe so groß zu wählen, daß das zu beobachtende Signal sehr deutlich und auch i.n .seiner Farbwirkung genau erkennbar ist. Da ;gleichzeitig die optische Einrichtung auch die nähere und weitere Umgebung des Signals erkennen läßt, so kann der Fahrer, ohne den Kopf zu wenden und ohne den Blick von der Mattscheibe abzuwenden, auch noch andere Signale, beispielsweise die Handbewegungen des Verkehräs,chutzmannes deutlich erkennen und verfolgen. ja, man kann sogar dass Gesichtsfeld der optischen Einrichtung so groß wählen, daß es ferner möglich ist; in der op tischen. Einrichtung auch gleichzeitig noch die den Fahrdamm kreuzenden Fuhrwerke und Personen zu beobachten, ohne dabei das optische Signal aus den Augen zu verlieren.The invention aims to address these disadvantages of the known devices through this. to avoid getting the lens through an opaque housing a 'screen is connected. It is achieved by the fact that on the ground glass, which is expediently still surrounded by a chinn of light, unaffected by the. daylight or from nearby light sources, the optical signal to be observed is clearly visible. This is not the only thing that can be observed on the screen optical signal, but also its surrounding area clearly recognizable. It is It is even possible to choose the field of view on the screen so large that it can The observed signal is very clear and also precisely recognizable in terms of its color effect is. There; at the same time the optical equipment also the near and far surroundings of the signal, the driver can without turning his head and without To avert your eyes from the screen, also other signals, for example clearly recognize and follow the hand movements of the traffic guard. Yes, one can even choose the field of view of the optical device so large that it is also possible; in the optical tables. Facility also at the same time the den Carriages and people crossing the road without losing sight of it Losing sight of the signal.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schaubildlich dargestellt. Ein Fahrzeug i befindet -sch auf dem Fahrdamm 2, über welschem die Signaleinrichtung 3 angebracht ist. Befindet sich der Wagen in der Nähe der Signaleänrichtun;g, so ist es infolge des Daches, q. dein Fahrer 5 nicht mehr möglich, das Signal zu sehen. Die optische Einrichtung 6, welche in Abb.2 dargestellt ist, besteht aus einer Linse a, welche in einem Gehäuse b vorn angeordnet ist; auf eine Mattscheibe c wird das Bild d :geworfen. Die Mattscheibe ist zweckmäßig durch Seiten- und Stirnwändee abgedeckt.An exemplary embodiment of the subject matter of the invention is shown diagrammatically in the drawing. A vehicle i is located on the embankment 2, above which the signaling device 3 is attached. If the wagon is in the vicinity of the signal installation, it is because of the roof, q. your driver 5 is no longer able to see the signal. The optical device 6, which is shown in Fig.2, consists of a lens a, which is arranged in a housing b at the front; the image d: is thrown onto a screen c. The ground glass is expediently covered by side and front walls.
