  Verfahren zur Herstellung einer als Leuchtauge an Fahrzeugschlusslichtern bestimmten
Transparentschale und nach dem Verfahren hergestellte Schale
Es sind Fahrzeugschlusslichter bekannt, bei denen die als Leuchtauge bestimmte Transparentschale nebst wenigstens einem rot gefärbten Lichtdurchlassbereich zur Bildung des Schlusslichtes einen farblosen Lichtdurchlassbereich zum Beleuchten des Kontrollschildes des Fahrzeuges aufweist. Oft ist auch noch ein gelb gefärbter Lichtdurchlassbereich zur Markierung der Bremsbetätigung vorgesehen. Bisher sind solche Transparentschalen in farblosem Werkstoff angefertigt und dann unter Freilassen des farblosen Durchlassbereiches durch Auftragen von Lackfarbe gefärbt worden. Dieser Farbauftrag erfolgt vorzugsweise innenseitig, doch verbleicht er beim Altern und blättert mit der Zeit ab.



   Die vorliegende Erfindung sucht diese Nachteile zu vermeiden und betrifft ein Verfahren zur Herstellung einer als Leuchtauge an Fahrzeugschlusslichtern bestimmten Transparentschale, deren Lichtdurchlassbereich teils gefärbt und teils farblos ist.



  Dieses Verfahren zeichnet sich dadurch aus, dass eine Schale aus farblosem Transparentwerkstoff gebildet und mit ihrer Innenseite zum satten Anliegen an wenigstens einem aus durchgehend gefärbtem Transparentwerkstoff bestehenden Schalenteil gebracht wird.



   Die nach diesem Verfahren hergestellte Transparentschale ist dadurch gekennzeichnet, dass die farblose Schale mit mindestens einem gefärbten innenseitigen Schalenteil unlösbar verbunden ist.



   Die Erfindung wird anschliessend anhand eines Verfahrensbeispiels näher erläutert.



   Es werde angenommen, die als Leuchtauge für ein Fahrzeugschlusslicht bestimmte Transparentschale müsse je einen gelben, roten und farblosen Lichtdurchlassbereich aufweisen. Für die beiden unterschiedlich gefärbten Lichtdurchlassbereiche werden entsprechende Schalenteile aus durchgehend gefärbtem Transparentwerkstoff, zum Beispiel Kunststoff, hergestellt, welche an ihrem Schalenboden einen zu diesen querstehenden kragenförmigen Rand aufweisen. Diese beiden gefärbten Schalenteile werden nebeneinander mit ihrer Innenseite auf die entsprechend ausgebildete Matrize einer Spritzform aufgesetzt.

   Der zugehörige Stempel der Spritzform belässt in seinem auf die Matrize und die Schalenteile aufgesetzten Zustand einen Hohlraum zur Bildung eimer äusseren Schale, welche mit ihrer Innenseite am Boden der beiden Schalenteile und an deren Rand satt anliegt und sich mit ihrem Rand darüber hinaus erstreckt. Das Verfahren besteht darin, bei geschlossener Spritzform die Aussenschale aus farblosem Transparentwerkstoff auf die beiden Schalenteile aufzu spritzen und sie dadurch miteinander und mit der Aussenschale zu einem einzigen Körper zu verbinden.



   Die beiden gefärbten Schalenteile kleiden dann den Boden der farblosen Schale aus und bilden in ihr einen zum Boden querstehenden kragenförmigen Rand, über den sich der Rand der farblosen Schale hinaus erstreckt und mit diesem vorstehenden Teil den farblosen Lichtdurchlassbereich bilden kann, dessen Fläche zum Schalenboden abgewinkelt ist, während der Schalenboden selbst die beiden gefärbten Lichtdurchlassbereiche ergibt. Vorzugsweise ist die eine Bodenfläche der beiden gefärbten Schalenteile facettiert, wobei dieselbe der farblosen Schale zugekehrt sein kann.



   Anstelle von zwei gefärbten Schalenteilen können ebensogut mehr als zwei oder nur ein einziger in der 'beschriebenen Weise mit der farblosen Aussenschale zu einem Transparentkörper verbunden werden.   



  
 



  Process for the production of one intended as a light eye on vehicle taillights
Transparent bowl and bowl made according to the process
Vehicle taillights are known in which the transparent shell intended as a luminous eye has, in addition to at least one red-colored light passage area for forming the rear light, a colorless light passage area for illuminating the license plate of the vehicle. Often a yellow light transmission area is also provided to mark the brake actuation. Up to now, such transparent shells have been made from a colorless material and then colored by applying lacquer, leaving the colorless passage area free. This paint is preferably applied on the inside, but it fades with aging and peeling off over time.



   The present invention seeks to avoid these disadvantages and relates to a method for producing a transparent shell intended as a light eye on vehicle taillights, the light transmission area of which is partly colored and partly colorless.



  This method is characterized in that a shell is formed from colorless transparent material and its inner side is brought into full contact with at least one shell part made from a continuously colored transparent material.



   The transparent shell produced by this method is characterized in that the colorless shell is inextricably connected to at least one colored inner shell part.



   The invention will then be explained in more detail using an example method.



   It is assumed that the transparent shell intended as a light eye for a vehicle tail light must each have a yellow, red and colorless light transmission area. For the two differently colored light transmission areas, corresponding shell parts are made from continuously colored transparent material, for example plastic, which have a collar-shaped edge on their shell bottom that extends transversely to them. These two colored shell parts are placed side by side with their inside onto the correspondingly designed die of an injection mold.

   The associated punch of the injection mold, when placed on the die and the shell parts, leaves a cavity to form the outer shell of the bucket, the inner side of which rests snugly against the bottom of the two shell parts and their edge and extends beyond it with its edge. The method consists in spraying the outer shell made of colorless transparent material onto the two shell parts with the injection mold closed and thereby connecting them to one another and to the outer shell to form a single body.



   The two colored shell parts then line the bottom of the colorless shell and form in it a collar-shaped edge that is transverse to the bottom and over which the edge of the colorless shell extends and with this protruding part can form the colorless light-permeable area, the surface of which is angled towards the bottom of the shell , while the bottom of the bowl itself provides the two colored light transmission areas. The one bottom surface of the two colored shell parts is preferably faceted, it being possible for the same to face the colorless shell.



   Instead of two colored shell parts, more than two or only a single one can just as easily be connected to the colorless outer shell in the manner described to form a transparent body.
