Description
Titel: AUSSENSICHERHEI?SRÜCKSPIEGES Anwendungsgebiet: Die Erfindung betrifft einen Außenrückspiegel, der in seiner X- und Y-Achse variable Krümmungen aufweist und für alle Kfz.Title: AUSSENSICHERHEI? SRÜCKSPIEGES Field of application: The invention relates to an outside rearview mirror that has variable curvatures in its X and Y axes and for all vehicles.
verwendet werden kann.can be used.
Zweck: Bei Außenrückspiegeln ist es aus Gründen der Sicherheit erforderlich, einen möglichst großen Bildwinkel zu sehen. Durch einen Blick in den Rückspiegel soll der Fahrer das beobachten können, was hinter und neben seinem Auto vorgeht, ohne daß er seinen Kopf drehen muß und somit für wenige Augenblicke das versäumt, was sich vor seinem Wagen ereignet. Was sich hinter und neben dem Fahrzeug befindet, soll im Riickspiegel in einem zusammenhängenden Bild zu sehen sein.Purpose: In the case of exterior rear-view mirrors, for reasons of safety, it is necessary to see the largest possible angle of view. By looking in the rearview mirror the driver should be able to observe what is going on behind and next to his car, without having to turn his head and thus neglecting for a few moments, what happens in front of his car. What is behind and next to the vehicle should be seen in the rearview mirror in a coherent picture.
Stand der Technik: Es ist bekannt, daß alle Fahrzeuge mit Außenrückspiegeln ausgerüstet sein müssen. Man unterscheidet folgende Typen: a) den normalen Planspiegel, b) den konvex gewölbten Spiegel und c> den Winkelapiegel.State of the art: It is known that all vehicles have exterior rear-view mirrors must be equipped. A distinction is made between the following types: a) the normal plane mirror, b) the convex mirror and c> the corner mirror.
Kritik des Standes der Technik: Alls Außenrückspiegel zeigen Mängel auf, welche die Sicherheit beeinträchtigen-.Criticism of the state of the art: All exterior rearview mirrors show defects which affect security-.
a) Der normale Planspiegel weist einen toten Winkel auf.a) The normal plane mirror has a blind spot.
b) er konvex gewölbte Spiegel ergibt ein verkleinertes Bild.b) the convex mirror results in a reduced image.
Dadurch ist die Abschätzung von Entfernungen und Geschwindigkeiten erschwert. Außerdem treten am-Rand Bildverzerrungen auf. This makes it possible to estimate distances and speeds difficult. In addition, image distortion occurs at the edge.
C) Der Winkelspiegel giDt in seiner r e c h t e n Hälfte den 1 i n k e n Bildteil wieder, der etwa dem toten Winkel entspricht, und im l-i n k e n Spiegel den r e c h t e n Bildteil. Der Pahrer ist somit gezwungen, gedanklich die beiden Bildteile zu vertauschen. Zudem sieht er unter gewissen Umständen einen Gegenstand doppelt, was zu Täuschungen Anlaß gibt.C) The right half of the corner mirror counts as 1 k e n part of the image which roughly corresponds to the blind spot, and in the l-i n k e n Mirror the right part of the picture. The pahrer is thus forced to mentally die to swap both parts of the picture. He also sees an object under certain circumstances double, which gives rise to deceptions.
Der Innenpanoramaspiegel ersetzt den Außenrückepiegel nicht.The inside panorama mirror does not replace the outside rearview mirror.
Bei ihm treten Sichtbehinderungen durch Fenster- und Türpfosten sowie durch Fahrgäste auf.With him there are visual obstructions through window and door posts as well by passengers.
Aufgabe: Der Erfindung liegt die auf'gabe zugrunde, den toten Winkel auszuschließen und somit die Sicherheit im Straßenverkehr wesentlich zu erhöhen.Task: The invention is based on the task, the blind spot and thus significantly increase road safety.
Lösung: Diese Aufgabe wird erfindurigsgemäß dadurch gelöst, daß der Planspiegel nach außen hin in einen gekrummten Spiegel ausläuft. Es handelt sich somit um eine Kombination eines Planspiegels mit einem Konvexspiegel. Ein von hinten sich näherndes Fahrzeug wird zuerst im Planspiegel gesehen; seine Geschwindigkeit und Art Kann optimal erkannt werden. Bei weiterer Näherung des Fahrzeuges gerät es in den toten Winkel des Planspiegels; sein Bild erscheint jedoch jetzt im gekrümmten Spiegel Damit ist der tote Winkel ausgeschaltet.Solution: This object is achieved according to the invention in that the Plane mirror ends in a curved mirror towards the outside. It is about thus a combination of a plane mirror with a convex mirror. One from behind approaching vehicle is first seen in the plane mirror; its speed and type Can be recognized optimally. When the vehicle approaches further it in the blind spot of the plane mirror; however, his image now appears in the curved one Mirror This eliminates the blind spot.
Erzielbare Vorteile: Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß man zu dem Blickwinkel eines Normalspiegels (siche Skizze Normalwinkel N < ) in übergehender Linie den toten Winkel (siehe Skizze T < ) ) erfassen kann. Da durch die äußere Krümnlung eine Verkleinerung und ein sehr großer Blickwinkel erreicht wird, sieht man die überholenden Fahrzeuge langsam voruberziehen. Die Erfindung vereinigt somit die Vorteile des Planspiegels, nämlich ein wirklichkeitsgetreues und verzerrungsfreies Bild, mit denen des gekrümmten Spiegels, nämlich des groBen Blickwinkels. Sie vermeidet die Nachteile des Winkel spiegels, nämlich Bildüberlappung und Bildvertauschung.Achievable Advantages: The advantages achieved with the invention exist especially in the fact that one goes to the viewing angle of a standard mirror (safe sketch Normal angle N <) in the overlying line the dead angle (see sketch T < )) can capture. Because through the outer Curvature a reduction and a very large perspective is achieved, you can see the overtaking vehicles move slowly forward. The invention thus combines the advantages of the plane mirror, namely a realistic and distortion-free image, with those of the curved one Mirror, namely the large viewing angle. It avoids the disadvantages of the angle mirror, namely image overlap and image interchange.
Beschreibung eines Ausführungsbeispieles: Ein ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.Description of an exemplary embodiment: An exemplary embodiment the invention is illustrated in the drawing and will be described in more detail below.
Der Spiegel besteht aus einem ganzen Stück.er innere Teil ist ein Planspiegel (Schnitt B - B) und der äußere Teil ist in seiner X-Achse gekrümmt und kann aich in der Y-Achse gekrümmt sein, um eine zu starke Verzerrung der Proporbionen in der Y-Achse zu vermeiden. Bei besonders großen Spiegeln (z.B. für LKW) kann auch der untere Planspiegelteil gekrümmt sein, damit auch bei hohen LKWs das Geschehen unmittelbar neben dem Fahrzeug beobachtet werden kann.The mirror is made of a whole piece; the inner part is a Plane mirror (section B - B) and the outer part is curved in its X-axis and can also be curved in the Y-axis in order to distort the proportions too much in the Y-axis. In the case of particularly large mirrors (e.g. for trucks), the lower plane mirror part must be curved, so that the action even with tall trucks can be observed directly next to the vehicle.
