Description

Fernsehempfänger mit Umfeldbeleuchtung durch Ausnutzung des vom Bildschirm ausgehenden Lichtes. -------------------- Die Erfindung betrifft einen Fernsehempfänger mit Umfeldbeleuchtung durch Ausnutzung des von der Rückseite des Bildschirms abgestrahlten Lichtes. Bei solchen Fernsehempfängern umschliesst die Bildumrandung oder Maske die Bildröhre an der annähernd zylinderförmigen Stelle ihres grössten Durchmessers, die räumlich hinter dem Bildschirm liegt. Infolge der Herstellungstoleranzen der Bildröhre ergeben sich bei ein und demselben Röhrentyp Unterschiede in dem grössten Durchmesser des Kolbens, so dass bei konstantem Innendurchmesser der Bildmaske Abstände zwischen der Bildmaske und der Bildröhre entstehen. Zur Beseitigung dieses Nachteils dient die Neuerung.Television receiver with ambient lighting by utilizing the light emanating from the screen. -------------------- The invention relates to a television receiver with ambient lighting by utilizing the light emitted from the rear of the screen. In such television receivers, the picture frame or mask surrounds the picture tube at the approximately cylindrical point of its largest diameter, which is spatially behind the screen. As a result of the manufacturing tolerances of the picture tube, there are differences in the largest diameter of the piston for one and the same type of tube, so that with a constant inside diameter of the picture mask, there are gaps between the picture mask and the picture tube. The innovation serves to eliminate this disadvantage.

Die Neuerung besteht darin, dass zwischen der Innenseite der Bildumrandung und dem Röhrenkolben ein elastischer Zwischenring vorgesehen ist, der sich dem jeweiligen Kolbendurchmesser der Bildröhre anpasst und an seiner Aussenseite eine Kerbe aufweist, die die Bildumrandung an ihrer Innen-' seite umschliesst. Die Tiefe der Kerbe ist vorzugsweise so bemessen,. dass sie dem maximalen Durchmesserunterschied der Bildröhre entspricht.The innovation is that between the inside of the picture border and the tubular piston is provided with an elastic intermediate ring, which is attached to the respective Adjusts the piston diameter to the picture tube and has a notch on its outside, which encloses the picture border on its inside '. The depth of the notch is preferably sized so. that they correspond to the maximum difference in diameter of the picture tube is equivalent to.

Zur näheren Erläuterung der Erfindung wird im folger-den Ausführungsbeispiel an Hand der Abbildung beschrieben. diese zeigt das Gehäuse 1 eines Fernsehempfängers mit einer Bildröhre 2 und einer Bildumrahmung oder Maske 3, deren Innenseite 4 die Bildröhre an der Stelle ihres grössten Durchmessers umfaßt. Um den Kolben der Bildröhre ist zur Vermeidung eines sichtbaren Abstandes zwischen der Maske und der Bildröhre ein elastischer Zwischenring 5 vorgesehen, der an der Vorderseite eine Kerbe 6 aufweist, deren Schenkel 7 und 8 die Innenseite der Maske 3 an beiden Seiten umfassen. Die Tiefe der Kerbe ist so gewählt, dass auch bei grössten Abweichungen des Kolbendurchmessers der Bildröhre die Innenseite der Maske noch umfasst wird.In order to explain the invention in more detail, the following is the exemplary embodiment described on the basis of the illustration. this shows the housing 1 of a television receiver with a picture tube 2 and a picture frame or mask 3, the inside 4 of which Includes picture tube at the point of its largest diameter. Around the piston of the picture tube is to avoid a visible distance between the mask and the picture tube an elastic intermediate ring 5 is provided, which has a notch 6 on the front side, the legs 7 and 8 of which encompass the inside of the mask 3 on both sides. the The depth of the notch is chosen so that even with the greatest deviations in the piston diameter of the picture tube, the inside of the mask is still gripped.

Der Schenkel 7 des elastischen Zwischenrings 5 ist vorzugs weise gewölbt ausgebildet und in seinem Aussehen dem sichtbaren Teil der Bildmaske angepasst.The leg 7 of the elastic intermediate ring 5 is preferably curved trained and adapted in its appearance to the visible part of the image mask.
