Description

FRbhMPFAGR MIT fRuJA. l'lüiRUdR ÜJMD AUbIjnR GERAUSjLlIL Es ist bekannt, Rundfunkempfängergehäuse, z. B. für Camping- Empfänger, derart veränderbar zu gestalten, daß das Gehäuse beim Tragen auf einen relativ kleinen, durch das Chassis gegebenen Rauminhalt zusammengeschoben werden kann, während das Gehäuse im eigentlichen Betriebszustand zur Verbesserung der Abstrahlfläche bzw. Verbesserung des Resonanzraumes durch Herausziehen seitlicher Teile dem Volumen nach vergrößert werden kann. FRBHMPFAGR WITH FRUJA. l'lüiRUdR ÜJMD AUbIjnR GERAUSjLlIL It is known to have radio receiver housings, e.g. B. for camping Receiver to be designed so changeable that the housing can be pushed together when carried to a relatively small volume given by the chassis, while the volume of the housing in the actual operating state to improve the radiating surface or improve the resonance chamber by pulling out lateral parts is increased can.

Andererseits können die Gehäuse von bekannten Fernsehempfängern mit Projektionsröhre in der Weise verändert werden, daß z. B. ein im Deckel befindlicher Spiegel, oder eine entsprechende Mattscheibe, zusammen mit dem Deckel herausklappbar ist.On the other hand, the housing of known television receivers with Projection tube can be changed in such a way that, for. B. one located in the lid Mirror, or a corresponding ground glass, can be folded out together with the lid is.

Die Neuerung ist demgegenüber dadurch gekennzeichnet, daß das die Mattscheibe aufweisende Gehäuseteil, oder die Mattscheibe selbst, mit Hilfe einer Ausziehvorrichtung parallel zum Gehäuse bzw. zur Querschnittsebene der Projektionsröhre herausziehbar ist und die Nachregulierung der Bildschärfe mittels einer zwischen der Mattscheibe und der Projektionsröhre angebrachten und verstellbaren Linsenanordnung erfolgt.The innovation is characterized by the fact that the Housing part having a focusing screen, or the focusing screen itself, with the help of a Extraction device parallel to the housing or to the cross-sectional plane of the projection tube can be pulled out and readjustment of the image sharpness by means of an between the focusing screen and the projection tube attached and adjustable lens arrangement he follows.

Die Neuerung ist anhand eines'Ausführungsbeispieles näher er- läutert : -0- Fig. 1 zeigt eine Ansicht des Gerätes im geschlossenen Zu- stand und Fig. 2 eine entsprechende Ansicht bei herausgezogenem Apparat.The innovation is explained in more detail using an purifies: -0- Fig. 1 shows a view of the device in the closed stood and 2 shows a corresponding view with the apparatus pulled out.

Statt der bei den üblichen Empfängern normalen Bildröhre ist eine Projektionsröhre A eingebaut, welche das Bild auf eine Mattscheibe B projeziert. Um das Bild vergrößern zu können, ist die Mattscheibe ausziehbar mit Hilfe einer Ausziehvorrichtung C angebracht. Vor der Projektionsrohre A ist eine verstellbare Linse zur Regulierung der. Bildschärfe angebracht. Das Fernsehgerät ist auf diese Weise auch als Großbildgerdt verwendbar.Instead of the picture tube that is normal for the usual receivers, there is a Projection tube A installed, which projects the image onto a screen B. In order to be able to enlarge the picture, the ground glass can be pulled out with the help of a Extractor C attached. In front of the projection tube A is an adjustable one Lens to regulate the. Image sharpness appropriate. The TV is on this Can also be used as a large screen device.

Die Mattscheibe kann statt aus Glas auch aus mattscheibenartigem, rollbare Kunststoff bestehen und ein ausziehbares, federnd gelagertes Gestänge aufweisen. tSchutzanspruche 1 Zeichnung (2 Fig.) Instead of glass, the screen can also consist of screen-like, rollable plastic and have an extendable, spring-mounted rod. t Protection claims 1 drawing (2 fig.)
