Description

Die Erfindung betrifft einen Spiegel, insbes. einen als Außenspiegel für LKW, PKW und Motorräder gedachten Rück­ spiegel. Ein solcher Rückspiegel kann aber auch als Fahrzeug- Innenspiegel Anwendung finden.The invention relates to a mirror, in particular as a Rear view mirrors for trucks, cars and motorcycles mirror. Such a rearview mirror can also be used as a vehicle Use interior mirrors.

Bekannt sind sowohl ebene als auch schwach gekrümmte Autorückspiegel, die jedoch aufgrund ihrer Formgebung einen für den Autofahrer von seinem Sitzplatz aus nicht einsichtigen Bereich - einen toten Winkel - aufweisen. Dieser nicht einsichtige Bereich ist besonders deshalb gefährlich, weil jedes überholende Fahrzeug, etwa auf der Höhe des Hinterrades, in diesen Bereich einfährt und daher für kurze Zeit vollständig aus dem Sichtkreis des Autofahrers verschwindet. Zusammen mit der Tatsache des oft relativ geringen Abstandes der Fahrzeuge zueinander, stellt dieser tote Winkel eine häufige Unfallursache im täglichen Straßenverkehr dar. Both flat and slightly curved are known Car rear-view mirror, however, due to its shape not one for the driver from his seat clear area - a blind spot. This non-transparent area is special because of this dangerous because of any overtaking vehicle, for example the height of the rear wheel, enters this area and therefore completely out of sight of the Driver disappears. Along with the fact of often a relatively small distance between the vehicles, this blind spot is a common cause of accidents in the daily traffic.  

Bekannt ist die Verwendung von Winkelspiegel als Auto­ rückspiegel und das Aufkleben eines Spiegelkeils auf einem Teil eines ebenen Autorückspiegels, um die Größe des nicht einsichtigen Bereichs zu verringern. Man er­ hält in diesem Fall zwei getrennte Bereiche, die durch die zwei Spiegelbereiche eingesehen werden können. Da die zwei Spiegelbereiche gegeneinander um einen Winkel zwischen 7° und 15° geneigt sind, überlappen sich diese einsichtigen Bereiche jedoch nicht. Infolgedessen nimmt das Auge einen abrupten Übergang eines überholenden Fahr­ zeuges von einem Bereich in einen anderen Bereich wahr. Dies wirkt für den Autofahrer selbst irritierend, insbes. deshalb, weil Anpassungsprobleme für das Auge entstehen, die Zeit, Konzentration und ein wechselndes Einschätzungs­ vermögen der Entfernung erfordern. Die Halterung für der­ artige Winkelspiegel ist zudem aufwendig und teuer. The use of angle mirrors as a car is known rear view mirror and sticking a mirror wedge on part of a flat car rear-view mirror to resize of the non-visible area. Man he in this case holds two separate areas that pass through the two mirror areas can be seen. There the two mirror areas against each other at an angle are inclined between 7 ° and 15 °, they overlap insightful areas, however. As a result, takes the eye made an abrupt transition from an overtaking drive true from one area to another area. This is irritating for the driver himself, especially. because there are problems with the eye, the time, concentration and a changing assessment require distance. The bracket for the like angle mirror is also complex and expensive.  

Bekannt sind ferner Autorückspiegel, die zumindest teilweise in eine Anzahl von parallel zueinander verlaufende Segmente derart unterteilt sind, daß optisch der Effekt eines gewölbten Spiegels simuliert wird.Car rear-view mirrors are also known, at least in part in a number of parallel to each other Segments are divided so that the effect is optical of a curved mirror is simulated.

Bei der Anordnung nach DE-OS 32 49 278 weisen diese Segmente eine dem zu simulierenden gewölbten Spiegel entsprechende Krümmung auf. Bei der Anordnung nach DE-OS 29 14 247 besteht ein zweiter Spiegelbereich aus schmalen ebenen Streifen, die alle mit einer Kante in der Ebene des ersten Spiegelbereiches liegen. Die Streifen sind der Länge nach gekrümmt ausgeführt. Bei einem Rückspiegel nach DE-OS 25 50 095 besteht der zweite Spiegelbereich aus mehreren nebeneinander liegenden Streifenprismen, deren Prismenwinkel vom Haupt-Flächenbereich nach außen abnimmt.In the arrangement according to DE-OS 32 49 278, these have Segments corresponding to the curved mirror to be simulated Curvature on. In the arrangement according to DE-OS 29 14 247 a second mirror area consists of narrow ones flat strips, all with an edge in the plane of the first mirror area. The stripes are the Lenght curved. With a rearview mirror after DE-OS 25 50 095, the second mirror area consists of several side-by-side strip prisms, their prism angles decreases from the main surface area to the outside.

Bei jedem dieser bekannten Spiegel besteht der Nachteil, daß der Spiegel keine einheitliche Dicke mehr aufweist. Die Spiegelhalterungen müssen vielmehr an den jeweiligen Rückspiegel angepaßt werden.Each of these known mirrors has the disadvantage that that the mirror no longer has a uniform thickness. Rather, the mirror mounts must be attached to the respective Rearview mirrors can be adjusted.

Der Erfindung liegt die Aufgabe zugrunde, einen Autorückspiegel zu schaffen, der möglichst keine nicht einsichtigen Bereiche aufweist, der keine Anpassungsprobleme des Auges hervorruft und der schließlich einfach und preisgünstig gestaltet in vorhandene Halterungen montiert werden kann, ohne daß diese Halterungen speziell an den Autorückspiegel angepaßt werden müßten. The invention has for its object a car rear view mirror to create, if possible, not insightful Areas that have no adjustment problems of the Eye and ultimately simple and inexpensive designed to be mounted in existing brackets can, without these brackets specifically on the car rear-view mirror would have to be adjusted.  

Ausgehend von dem bekannten Fahrzeug-Rückspiegel, der zumindest teilweise in eine Anzahl von N parallel zueinander verlaufende, derart gestaltete Segmente unterteilt ist, daß optisch der Effekt eines gewölbten Spiegels simuliert wird, wobei die Segmente eine dem zu simulierenden gewölbten Spiegel entsprechende Krümmung aufweisen, besteht die Erfindung darin, daß die Breite der jeweiligen Segmente derart gewählt ist, daß die Stufenhöhe der Segmente untereinander gleich ist.Based on the well-known vehicle rear view mirror, which at least partially in a number of N parallel to each other running segments designed in this way is that visually simulates the effect of a curved mirror , the segments being the one to be simulated curved mirror have a corresponding curvature the invention in that the width of each Segments is chosen such that the step height of the segments is equal to each other.

Außer der Tatsache, daß ein solcher erfindungsgemäßer Spiegel die o. g. Bedingungen erfüllt, bietet er den wei­ teren Vorteil, daß er für den Autofahrer ein wesentlich ruhigeres Bild reflektiert als es bei den bisher bekannten Spiegeln der Fall ist.Except for the fact that such an inventive Mirror the above Conditions, he offers the white ter advantage that it is an essential for the driver Reflects a calmer picture than it does with the previously known Flipping is the case.

Ein Ausführungsbeispiel des erfindungsgemäßen Autorück­ spiegels ist in der Zeichnung dargestellt.An embodiment of the car back according to the invention mirror is shown in the drawing.

Es zeigen:Show it:

Fig. 1 einen Rückspiegel gemäß der Erfindung in Aufsicht, Fig. 1 is a rear-view mirror according to the invention in top view,

Fig. 2 eine Seitenansicht des Rückspiegels nach Fig. 1, Fig. 2 is a side view of the rear-view mirror according to Fig. 1,

Fig. 3 die der Abbildungsfunktion zugrunde liegende ge­ krümmte Kurve, Fig. 3, the mapping function underlying ge arched curve,

Fig. 4 einen Ausschnitt aus der Darstellung gemäß Fig. 2 in stark vergrößertem Maßstab, Fig. 4 shows a detail from the representation according to Fig. 2 in greatly enlarged scale;

Fig. 5 einen ebenfalls vergrößerten Ausschnitt der Dar­ stellung gemäß Fig. 3. Fig. 5 is a likewise enlarged detail of the Dar position shown in FIG. 3.

Wie sich aus den Darstellungen gemäß Fig. 1 und 2 ergibt, besteht der erfindungsgemäße Autorückspiegel 1 aus zwei Abschnitten 2 und 3. Der Abschnitt 2 stellt den ebenen Teil des Rückspiegels dar, während der Abschnitt 3 aus einzelnen Segmenten besteht. Diese Segmente weisen eine Krümmung auf entsprechend der in Fig. 3 dargestellten Kurve 5. Die Stufenhöhen S der einzelnen Segmente sind konstant, d. h. sie haben jeweils das gleiche Maß. Dement­ sprechend ändert sich die Breite b1 . . . bn in Abhängig­ keit von der Krümmung der Kurve 5.As is apparent from the illustrations according to FIGS. 1 and 2, the automotive rearview mirror 1 according to the invention consists of two sections 2 and 3. Section 2 represents the flat part of the rearview mirror, while section 3 consists of individual segments. These segments have a curvature corresponding to curve 5 shown in FIG. 3. The step heights S of the individual segments are constant, ie they have the same dimensions. Accordingly, the width b 1 changes . . . b n as a function of the curvature of curve 5 .

Diese Ausbildung des Spiegels ist in Fig. 4 und 5 in vergrößertem Maßstab nochmals gezeichnet, woraus deut­ lich zu erkennen ist, daß die Gesamtspiegeldicke auch im Bereich B der Segmente 3 konstant ist, so daß übliche Spiegelhalterungen für einen solchen Fahrzeugrückspiegel verwendet werden können.This design of the mirror is drawn again in FIGS. 4 and 5 on an enlarged scale, from which it can be seen clearly that the total mirror thickness is also constant in region B of the segments 3 , so that conventional mirror mounts can be used for such a vehicle rear-view mirror.

Als besonderer optischer Effekt hat sich herausgestellt, daß durch die konstante Stufenhöhe S der Einzelsegmente 3 eine wesentlich ruhigere Abbildung im Bereich der Segmen­ te 3 erzielt wird, was für den Fahrzeuglenker von erheb­ lichem Vorteil ist.As a special optical effect, it has been found that the constant step height S of the individual segments 3 results in a much quieter image in the region of the segments 3 , which is of considerable advantage for the vehicle driver.

In Fig. 2 und 4 ist noch die üblicherweise erforder­ liche Verspiegelung 4 eingezeichnet.In Fig. 2 and 4, the usually required Liche mirroring 4 is still drawn.
