Description
Um T-lnglücksfälle -an verkehrsreichen Straßenkreuzungen zu vermeiden, ist es bekannt, an .diesen Kreuzungen Verkehrsspiegel anzubringen. Sie haben,den Zweck, dem Fahrer yon Kraftfahrzeugen aus einiger Entfernung vor der Kreuzung das Herannahen eines Fahrzeuges aus der Seitenstraße sichtbar zu machen. Der Nachteil der bisher bekannten Verkehrsspiegel, die über der Straßenkreuzung aufgehängt werden, ist der, daß die einzelnen Spiegel unten abgestumpft sind, weshalb das herannahende Fahrzeug nicht bis dicht zur Kreuzung gesehen werden kann. Es entsteht nämlich ein toter Winkel, in welchem das letzte Stück. der Seitenstraße vor der Kreuzung nicht erfaßt wird. Ferner siind diese Spiegel meistens -in, vertikaler Richtung eben, oder nur- ein verhältnismäßig kleines Stück ist nach unten leicht gekrümmt. Je nach der Neigung des ebenen Stückes erscheint nur ein kleines Stück der Seitenstraße..im Blickfeld. Der Zweck der Erfindung ist, diese Verkehrsspiegel durch besondere Formgebung verkehrssicherer zu gestalten, als es bisher der Fall war.To avoid accidents at busy intersections, it is known to install traffic mirrors at these intersections. They have the Purpose, the driver of motor vehicles from some distance in front of the intersection To make the approach of a vehicle visible from the side street. The disadvantage the previously known traffic mirrors that are hung over the intersection, is that the individual mirrors below are blunted, which is why the approaching Vehicle cannot be seen right up to the intersection. Because there is a blind spot in which the last piece. the side street in front of the intersection is not is detected. Furthermore, these mirrors are mostly flat in the vertical direction, or only a relatively small piece is slightly curved downwards. Depending on the slope of the flat piece appears only a small piece of the side street Field of view. The purpose of the invention is to shape these traffic mirrors by special means make it safer than ever before.
Das wird bei einem Verkehrsspiegel zürn Aufhängen oder Aufstellen an Straßenkreuzungspunkten, dessen Spiegelflächen sich aus mehreren, vorzugsweise zwei-oder .vier, auf- der Spitze stehenden Dreiecksegmentflächen zusammensetzen, erfindungsgemäß dadurch erreicht, daß die einzelne Spiegelsegmentfläche -in vertikaler Richtung in Form einer Kreiszylindlerfläche mit einem z«eckentsprechenden Radius gewölbt ist, während sie 2n horizontaler Richtung eben. verläuft.In the case of a traffic mirror, this becomes a matter of hanging or setting up at road intersections, the mirror surfaces of which are made up of several, preferably assemble two or four triangular segment surfaces standing on top, according to the invention achieved in that the individual mirror segment surface -in vertical Direction in the form of a circular cylinder surface with a radius corresponding to the zigzag is arched, while it is flat in the horizontal direction. runs.
Die einzelne Spiegelfläche ist von oben nach unten gleichmäßig gekrümmt, so daß bereits aus -weiter Entfernung,der Einblick in die Seitenstraße mögich isst.The single mirror surface is evenly curved from top to bottom, so that a view of the side street is possible from a great distance.
Ferner .ist die einzelne Spiegelsegmentfläche in horizontaler Richtung eben, so daß kein verzerrtes Bild entsteht, wie das bei konkaven oder konvexen Spiegelnder Fall ist.Furthermore, the individual mirror segment surface is in the horizontal direction just so that there is no distorted image, as is the case with concave or convex reflectors Case is.
In, der Zeichnung ist der Erfindungsgegenstand erläutert.The subject of the invention is explained in, the drawing.
Abb. r zeigt den über der Kreuzung befestigten Verkehrsspiegel, der aus vier von oben nach unten, glenchrnäß,ig in Farm einer Kreiszylinderfiüche gewölbten, spitz zulaufenden Spiegelsegrrnentflächen besteht.Fig.r shows the traffic mirror attached above the intersection, the of four curved from top to bottom, glenchrnäßig in the form of a circular cylinder, tapering mirror green surfaces.
Abb.2 zeigt den Querschnitt des Verkehrsspiegels im Schnitt A-B. Hieraus ist ersichtliich, daß die einzelnem. Spiegelsegmentflächen in horizontaler Richtung gerade sind.Fig.2 shows the cross-section of the traffic mirror in section A-B. From this it can be seen that the individual. Mirror segment surfaces in the horizontal direction are straight.
