Description
Die Erfindung bezieht sich auf eine Vorrichtung, mittels derer das seitliche Gesichtsfeld eines Fahrzeugfensters, insbesondere einer Windschutzscheibe von Kraftfahrzeugen, erweitert wird. Der Rahmen der Fahrzeugfenster verdeckt dem Fahrer häufig Gegenstände, welche in der Richtung schräg nach vorn zum Fahrzeug liegen.The invention relates to a device by means of which the lateral field of view of a vehicle window, in particular a windshield of motor vehicles will. The frame of the vehicle window often hides objects from the driver, which are inclined in the direction lie in front of the vehicle.
Zur Beseitigung dieses Nachteiles sind bereits sphärische Linsen verwendet worden, die am seitlichen Rande einer Kraftfahrzeugwindschutzscheibe befestigt sind. Diese Linsen haben jedoch, die Eigenschaft, alle Koordinaten des zu beobachtenden Objektes gleichmäßig zu verkleinern. Der Fahrer hat dann einmal die Fahrstraße in der Größe vor sich, wie sie sich ihm durch die Windschutzscheibe darbietet, und beim Durchblick durch die Linse ein zweites stark verkleinertes Bild hiervon. Dieser Wechsel in der Wahrnehmung ist für das Auge anstrengend und schädlich, so daß gewöhnlich auf die Anwendung einer solchen Linse verzichtet wird.Spherical lenses have already been used to eliminate this disadvantage, which are attached to the side edge of a motor vehicle windshield. These lenses however, have the property that all coordinates of the object to be observed are uniform to zoom out. The driver then has the route in front of him in the size how it presents itself to him through the windshield, and when looking through it Lens a second greatly reduced image of this. This change in perception is stressful and harmful to the eye, so usually on the application of a such a lens is dispensed with.
Die Erfindung sucht diesen Mangel zu verringem, indem sie an die Stelle einer sphärischen Linse eine konkave Zylinderlinse setzt, durch die die zu betrachtenden Objekte nur in der waagerechten Richtung, nicht aber in der senkrechten Richtung zusammengezogen erscheinen.The invention seeks to reduce this deficiency by replacing a spherical one Lens sets a concave cylindrical lens through which the objects to be viewed only contracted in the horizontal direction but not in the vertical direction appear.
Da diese Zylinderlinsen außerdem den Vorteil haben, daß sie sich über die ganze Höhe des Fensters erstrecken können, ist der Übergang von dem normalen zum nur einseitig verzerrten Bild ein weniger schroffer als zu einem stark verkleinerten Bild, wie es mit der sphärischen Linse erzeugt wird.Since these cylindrical lenses also have the advantage that they extend over the entire height of the window, the transition from the normal to the one-sided is only distorted image a less sharp than to a much reduced image like it with the spherical lens is generated.
Auf der Zeichnung ist die Erfindung in zwei Atisführungsformen dargestellt. Es zeigen:In the drawing, the invention is shown in two Atisführungformen. It demonstrate:
Abb. ι einen waagerechten Schnitt durch einen Teil der Windschutzscheibe, den zugehörigen Türpfosten mit anschließendem Fenster,Fig. Ι a horizontal section through part of the windshield, the associated Door post with adjoining window,
Abb. 2 einen Querschnitt durch die Zylinderlinse undFig. 2 shows a cross section through the cylinder lens and
Abb. 3 einen gleichen Schnitt durch die Windschutzscheibe mit aufgekitteter Linse.Fig. 3 shows the same section through the windshield with the lens cemented on.
Die Wirkungsweise der Vorrichtung ist aus der Abb. 1 ersichtlich. Das Auge des Fahrers befindet sich an dem Punkt 1 und blickl durch die in einem Rahmen 4 sitzende Windschutzscheibe 3 und durch das Seitenfenster 7, welches in einem Rahmen 6 befestigt ist. Der Eckpfeiler ist mit 5 bezeichnet. Durch den Eckpfeiler 5 sowie die Rahmen 4 und 6 wird dem Fahrer ein Teil der Sicht entzogen. An der Seite der Windschutzscheibe wird die Linse 2 angebracht, welche den Gang der Lichtstrahlen so beeinflußt, daß auch der von dem Eckpfeiler verdeckte seitliche Teil der Fahrbahn gesehen werden kann. Der Pfeil 8 gibt die Lichtablenkung durch eine solche Linse an.The mode of operation of the device can be seen in FIG. The driver's eye is located at point 1 and looks through the windshield seated in a frame 4 3 and through the side window 7, which is fastened in a frame 6. Of the Corner pillar is denoted by 5. Through the corner pillar 5 and the frame 4 and 6 is Part of the view is withdrawn from the driver. On the side of the windshield is the Lens 2 attached, which affects the path of the light rays so that that of the corner pillar concealed side part of the roadway can be seen. The arrow 8 indicates the deflection of light by such a lens.
Die Zylinderlinsen können entweder mit einer Planfläche unmittelbar auf die Windschutzscheibe aufgekittet oder aber mit einer Gummidichtung aufgesetzt werden. Im letzten Falle entsteht zwischen Linse und Scheibe eine Luftschicht, die ähnlich wie bei Doppelfenstern ein Beschlagen der Glasscheibe verhindert The cylinder lenses can either have a flat surface directly on the windshield puttied on or put on with a rubber seal. In the latter case, it arises between the lens and the pane a layer of air that, similar to double windows, prevents the glass pane from misting up
