Description

Chässis-support pour appareil electronique ä tube cathodique L'invention a pour objet un chässis-support pour appareil 61ectronique ä tube cathodique. Support frame for electronic device with cathode-ray tube The subject of the invention is a support frame for electronic device with cathode-ray tube.

Les appareils electroniques comportant un tube cathodique ont un encombrement important. Ceci est dü aux dimensions importantes du tube cathodique et au fait qu'il existe des espaces vides entre les parois latd- rales du tube cathodique et 1e chässis supportant les autres composants de 1'appareil, 1e chässis etant g6n6rale- ment dispose perpendiculairement ä Faxe du tube cathodique. Tel est le Gas, en particulier, des appareils recepteurs de t616vision dans lesquels les dimensions du tube cathodique sont particulierement grandes par rap- port ä Gelles des autres composants de 1'appareil. Electronic devices comprising a cathode ray tube have a large size. This is due to the large dimensions of the cathode ray tube and to the fact that there are empty spaces between the side walls of the cathode ray tube and the frame supporting the other components of the apparatus, the frame generally being placed perpendicular to the axis. of the cathode ray tube. Such is the case, in particular, of television receivers in which the dimensions of the cathode ray tube are particularly large compared to the dimensions of the other components of the apparatus.

Le but de la prdsente invention est de rdduire cet encombrement. The object of the prdsente invention is to reduce this size.

Le chässis-support suivant Finvention est caractdris6 par 1e fait que sa forme g6n6rale reproduit sensiblement Gelle du tube cathodique, au moins pour ce qui est de la projection horizontale des 616ments qui en constituent 1e pourtour. The support frame according to the invention is characterized by the fact that its general shape substantially reproduces the form of the cathode-ray tube, at least as regards the horizontal projection of the elements which constitute its periphery.

Le dessin repr6sente, ä titre d'exemple, une forme d'execution de 1'objet de 1'invention. The drawing shows, by way of example, one form of execution of the object of the invention.

La fig. 1 est une vue schdmatique de dessus d'un appareil rEcepteur de te16vision dont 1e chässis est du type connu, et la fig. 2 est une vue sch6matique de dessus d'un appareil r6cepteur de t616vision equip6 d'un chässis constituant une forme d'ex6cution de Fobjet de 1'in- vention. fig. 1 is a schematic top view of a television receiver, the chassis of which is of the known type, and FIG. 2 is a schematic top view of a television receiver equipped with a chassis constituting one embodiment of the object of the invention.

Le tdldviseur repr6sent6 ä la fig. 1 comporte un tube cathodique 1 et est support6 par un chässis vertical 2 qui est dispos6 derriere le tube cathodique et perpendi- culairement ä laxe de celui-ei. Le chässis 2 Supporte les divers composants 6lectroniques du t616viseur tels que des r6sistances, des condensateurs, des tubes 61ectroni- ques, etc. 0n voit Sur la figure qu'entre 1e chässis 2 et les parois latdrales 3 et 4 du tube cathodique 1 il existe des espaces inoccup6s importants. The television set represented in fig. 1 comprises a cathode ray tube 1 and is supported by a vertical frame 2 which is arranged behind the cathode ray tube and perpendicular to the axis thereof. Chassis 2 Supports the various electronic components of the television set such as resistors, capacitors, electronic tubes, etc. It can be seen from the figure that between the frame 2 and the side walls 3 and 4 of the cathode ray tube 1 there are significant unoccupied spaces.

De plus, an voit que si 1'on dispose des 616ments de rdglage de 1'appareil 5, par exemple des potentio- metres, Sur 1e chässis, de maniere ä grouper tous les composants sur ce dernier, les tiges de commande 6 de Ges 616ments de r6glage sont n6cessairement disposees sur le cöt6, mais ä 1'arriere du boitier 7 de 1'appareil, ce qui ne facilite pas les opdrations de r6glage. Moreover, it is seen that if one has the adjustment elements of the device 5, for example potentiometers, on the chassis, so as to group all the components on the latter, the control rods 6 of Ges 616 adjustment elements are necessarily arranged on the side, but at the rear of the casing 7 of the apparatus, which does not facilitate the adjustment operations.

Dans le Gas de la fig. 2, au contraire, la forme g6n6- rale du chässis correspond, au moins dans un plan, ä Gelle du tube cathodique. In the Gas of fig. 2, on the contrary, the general shape of the frame corresponds, at least in one plane, to the shape of the cathode ray tube.

Dans RTI ID="0001.0271" WI="15" HE="4" LX="1270" LY="1803"> 1'exemple repr6sent6, 1e chässis est compose de deux plaques verticales 8 et 9 paralleles aux parois laterales 10 et 11 du tube 1 et rdunies par une plaque verticale 12 perpendiculaire ä Faxe dudit tube catho- dique. 0n voit donc qu'en section horizontale 1e chässis 6pouse approximativement la forme du tube catho- dique 1. In RTI ID="0001.0271" WI="15" HE="4" LX="1270" LY="1803"> the example represented6, the first frame is composed of two vertical plates 8 and 9 parallel to the side walls 10 and 11 of tube 1 and joined by a vertical plate 12 perpendicular to the face of said cathode ray tube. It is therefore seen that in horizontal section the frame 6 approximately matches the shape of the cathode-ray tube 1.

De plus 1e chässis est muni d'un axe vertical 14, conform6ment au brevet franrais NO 1146450 du 5 avril 1956, autour duquel il peut tourner. In addition the first frame is provided with a vertical axis 14, conform6ment to French patent NO 1146450 of April 5, 1956, around which it can rotate.

Dans cette exkution si des 616ments de r6glage 5 sont disposds aux extr6mit6s du chässis, leurs tiges de commande 6 peuvent alors etre disposdes Sur les cöt6s du boitier 7, mais tres en avant, et dans une position de biais qui facilite leur manoeuvre et permet, dans 1e Gas oü 1'appareil electronique est un t616viseur, un contröle plus ais6, sur 1'image fournie par 1e tube, des reglages effectues ä 1'aide de Ges 616ments. In this execution, if adjustment elements 5 are arranged at the ends of the frame, their control rods 6 can then be arranged on the sides of the box 7, but very forward, and in a slanted position which facilitates their operation and allows, in the Gas where the electronic device is a television set, easier control, on the image provided by the tube, of the adjustments made using Ges 616ments.
