v N E CATHODE-RAY TUBE stirron'imajy p L srRUcrnaE' Carl]. Steinke,0hicago, m sssaortszemm Radio Corporation, a corporationof' Illinois 5 Application December 17, 1949, Serial nos sassr 1 adequate support for the tube and at the same time allow for easy removability thereof for replacement purposes. To solve this problem many complicated and expensive supporting structures have been devised which usually comprise a plurality of snap fasteners, belts, straps and other complicated linkage arrangements,
It is an object of the presentinvention to provide a supporting structure forthe image-reproducing tube of a television receiver, or the like, that is exceedingly simple and economical in construction, and which not only provides an adequate yet removable support for the reproducing tube, but also acts as a fr'ame'for the image screen of the tube, a cushion between the tube and the receiver panel, a dust shield;-and as an insulator when used to support metal-cone type reproducing tubes.
The features of this invention which are believed to be new are set forth with particularity in the appended claims. The invention itself, however, together with further objects and advantages thereof may best be understood by reference to the following description when taken in conjunction withthe accompanying drawing, in which:
Figure 1 shows a front view of the supporting structure of the invention,
Figure 2 shows a sectional view thereof, and,
Figure 3 shows the supporting structure mounted on the chassis of a television receiver to support the image-reproducing tube of the receiver.
The supporting structure III of the present invention, as shown in Figures 1 and 2, is a, flexible molded unitary structure composed, preferably, of a plastic substance such as polyethylene. The structure I includes a cylindrical-shaped skirt section II which is formed to encompass the enlarged end of a cathode-ray reproducing tube and to extend into a circular aperture formed in the front panel of a television receiver. Formed integral with the cylindrical skirt II is a flange I2 which is shaped to have an annular ring portion I3 extending beyond the end of skirt II, and which also is shaped to have an annular re-entrant lip I4. A transverse depending flange I5 is also formed integral with the cylindrical 4 Claims. (01.177416).
skirt'for mounting the structure I0 to the chassis of the television receiver.
Figure 3 shows a chassis I6 of a television receiver mounted in a cabinet IT. The chassis I6 supports a cathode-ray image-reproducing tube I8 which extends through a yoke I9 and rests on a block 20. 1 The supporting structure I0 is mounted to one end .of chassis I6 by means of a plate 21 and screws 22 which act to hold the flange section I5 of the structure in firm engagement with the chassis I6.'-When the chassis is moved into place inthe cabinet IT, a portion ofthe skirt encompassing the large end of the tube extendsinto an aperture in the front panel 23' of cabinet. This aperture is surroundedbyi'a bezel ring, 24 andcovered by a glass viewingplate 25 clamped to the bezel ring.
:Whenthechassis is in place, the annular ring plate 25, and'the lip section I4 bears against pointed out, a portion of the skirt II extends into the aperture in the front panel of cabinet, I]. In this manner, the structure It! forms a secure mounting for the-tube I8. In addition, the struc- "from the aperture in this panel. Moreover, the
lip section I4 of the structure also acts as a frame for the image screen of the tube I8. When the tube I8 is of the metal-cone type, this cone is usually maintained at an extremely high potential, and the structure II] also acts as an insulator between the cone and the metal bezel ring 24 and other parts of the receiver. Due to the fact that it is flexible in nature, the structure I0 may easily be slipped off the enlarged end of tube I8 when the chassis IB is removed from the cabinet I'I, thus allowing the tube I8 to be easily removed from the receiver for replacement purposes.
While a particular embodiment of the invention has been shown and described modifications may be made and it is intended in the appended claims to cover all such modifications as fall within the true spirit and scope of the invention.
I claim:
1. A flexible unitary structure for supporting on the chassis of a television receiver a cathoderay tube having an enlarged end portion projecting a given distance, beyond said chassis and enclosed by a face plate serving as an image screen, said structure comprising: a skirt section having a configuration corresponding to the configuration of said enlarged end portion of said tube for encompassing said end portion and having an axial length approximately equal to said distance; a flange section formed integral with one end of said skirt section including a shoulder portion and a re-entrant lip portion for bearing against said face plate and providing an image frame therefor; andga depending flange section formed integral with=theopposite end of said skirt section for mounting said structure to said chassis.
2. A flexible unitary structure for supporting on the chassis of a television receiver a cathoderay tube having an enlarged end portion project.- ing a given distance beyond said chassis and en"- closed by a face plate serving-asan imagescreen to be viewed through an aperture in a panel of said receiver, said structure, comprising; a skirt section for extending into said aperture having screen to be viewed through a transparent viewtransverse dimensions corresponding approxi-- mately to the dimensions of said aperture, having a configuration corresponding; to the configuration of said enlarged endpottion; oi'saidtube for encompassing said. ends-portion and hav n an axial length approximately; equal to said (distance; a flange section formed integral. with-one, endof said skirt section including a shoulder portion and a re-entrantlip portion for bearing against said faceplate andproviding an imageframe therefor; and a depending flange section formed integral with the opposite end of said skirt, sectionfor mounting said structure to. said chassis.
3. A flexible unitary structure for supporting on the chassis-of a television receiver a. cathoderay tube having an enlarged.end'portionprojecting a given distance-beyond said chassis and enclosed by a face plate serving as'an image screen to be viewed through an aperture in the panel of said receiver, said structure comprising: a skirt section for extendin into said aperture having transverse dimensions corresponding approximately to thedimensions of said aperture, having a configuration corresponding to the configuration of said enlarged end portion of said tube for encompassing said end. portion and having anaxial length-approximately equal to said distance; a shoulder section formed: integral with one end of said skirt and extending inwardly from said skirt over said :face platqa i e-entrant ingplate covering a circular aperture in a panel of said receiver, said structure comprising: 9. cy-
lindricalskirt section for extending into said aperture, having a diameter corresponding approximately to the diameter of said aperture and for encompassing said enlarged end portion of said tube, and further having an axial length approximately equal to said distance; an annu- .lar shoulder section formed integral with one end of; saidskirt and extending inwardly from said skirt over said face plate; a re-entrant lip sec- CARL J; R F R-amass CITED Y The following .reierences are of record in, the
