United States Patent p I 2,884,626 -eonn" ATION TELEVISION CABINET AND 1 PICTURE TUBE MOUNTING Lyman Roger Skaneateles, and Eric 0. Peterson, "Syracuse, N. assignor's to General Electric Company, a corporation of New York Application September 15, 1955, Serial No. 534,426 8 Claims. (Cl. 340-367) This invention relates to a novel cabinet for devices including cathode-ray tubes, which the .device also provides a means for mounting the cathode-ray tube.
There are numerous electronic devices which utilize cathode-ray tubes. One of the more common is the television receiver which is intended for use in large numbers in homes. These receivers are usually produced using mass production techniques. In the use of such techniques, any means which serves to reduce the cost of'the material and the labor involved in the final assembly of the television receiver would reduce the ultimate selling price of such devices to consumers and would speed up their production. The prior cabinets for such devices of which we are aware usually provide a cabinet structure, and a separate structure for supporting the cathode-ray tube. The separate structure may support the tube either ori-the chassis of the device which is mounted in the cabinet, or the tube supporting structure may be secured in some manner to the cabinet itself. In any case, those d'e'v'ices'of which we are aware, require a large number of parts and in the assembly of such devices, a large number of assembly steps are required.
Therefore, it is an object of this invention to provide a novel cabinet for electronic devices including cathode-ray tubes which is provided with a relatively simple structure tube. i It' is another object of our invention to provide a novel cabinet for devices including cathode-ray tubes which cabinet provides a means for mounting the cathoderay tube on the cabinet and which has a minimum number of parts arranged in such a manner wherein the assembly may be carried out with a minimum number of steps.
Briefly, the objects of this invention are achieved in one form by the provision of a cabinet structure including abody portion which may be formed out of a single 7 sheet of metallic material. The formation may take place by punching or cutting the sheet to the desired shape. When assembled, the body portion may have a top, bottom; and a pair of sides interconnecting the top and the bottom. The front and rear openings are usually providedat each end of the body portion. In order to provide rigidity and to accommodate tubes of different size and shape, the endsof the top, bottom, and sides adjacent to the front opening may be bent inwardly. Tabs which are adapted to conform to the periphery of the cathoderay tube to retain it are formed at the inner edge of the inwardly .bent portions so as to lie in the plane of the periphery of the tube. The cathode-ray tube is placed between the'tabs and a strap is wrapped around the outside. of the 'tabs was to depress them inwardly against the surface ofthe cathode-ray tube. Suitable means are provided on the ends of the strap whereby it may be tightened to cause the tabs to grip firmly the cathode-ray tube.
The novel features which we believe to be characteristic of our invention are set forth with particularity in the appended claims. Our invention itself, both as to its in addition to mounting which cabinet may Patented Apr. 28, 19 59 structure and manner of use, together with further advantages and objects thereof, may best be understood in conjunction with the accompanying drawing, in which:
Figure 1 is a side view of a television cabinet embodying our invention with a portion cut away to show the interior construction;
Figure 2 is a partial side view of the television cabinet embodying our invention illustrating the final assembly of a television tube into the cabinet;
Figure 3 is a front view of the television cabinet illustrated in Figure l, and;
Figure 4 is a plan view of a shaped blank of material embodying our invention which when folded assumesthe configuration of the cabinet illustrated in Figure 1.
In Figure 1 there is shown a cabinet designated generally by reference numeral 1 for electronic devices, be formed out of a single sheet of be punched or cut to a desired metal. The material may have the generally rectangular shape and then folded to configuration illustrated.
In Figure 3 of the drawing it may be seen that the cabinet includes a body portion constituted by the top 2, the bottom 3, and the sides 4 and 5 interconnecting the top and the bottom. As illustrated, these elements define a front opening 6 and a rear opening into which a chassis supporting an electronic device may be inserted. The front opening 6 is adapted to expose the face of the cathode ray tube forming a part of the device.
Extensions are provided at substantially a right angle to one of the top 2, bottom 3 and sides 4 and 5. The extensions are provided with first portions constituted by flanges 7 which may project into the plane of the front opening 6 and may be made as Wide or narrow as desired. At substantially the center of each flange 7 there is provided a second portion of the extensions in the form of tabs or projections 8, which is preferably out of the thereon for mounting and supporting the cathode-ray same sheet of metal. The tabs 8 extend at substantially a right angle to the plane of the flanges 7 in the direction away from the body portion and the plane of the front opening 6. Howevenit should be understood that if the flanges 7 extend in a direction other than that illustrated, the tabs 8 must only extend to conform to the peripheryof the cathode-ray tube. A strap 9 formed of any suitable flexible material such as a metal is wrapped around the outside of the tabs 8 and is tightened to support the tube. The tightening of the strap is effected in the form i the flanges 7 and tabs 8.
of our invention illustrated by a pair of upstanding brackets 10 provided on each end of the strap 9. The length of the tabs 8 is such that they may be easily forced into engagement with the surface of the tube. through these brackets and upon rotation will pull the ends of the strap together. The means illustrated for tightening the strap is but merely one of many which can be used. After assembly of the tube in the cabinet, a suitable cover (not shown) which supports a piece of over the front of securing means. v A cabinet embodying our invention may be fabricated out of a single sheet of material which may be metal. By punching and/or cutting, an elongated blank havingthe configuration shown in Figure 4 is formed. Score the tube and cabinet and held by a lines 14 are provided to form panels which will consti" 3, and sides 4 and 5. Add-itute the top 2, the bottom tional score lines 15 form the extensions comprised by carried out, the blank may configuration in the cabinet illustrated in Figures 1-3.
While a complete metal enclosure is shown and de scribed, it is readily understood that the cabinet does transparent safety glass may be placed.
After these steps have been be folded in, the proper direction along the score lines '14 and 15m assume the not have to be so formed. Thus, it may be desired to form only three sides of the cabinet blank and the equip ment chassis itself may constitute the bottom or one of the other enclosure walls.
Other changes in the construction of the cabinet may be found desirable. For instance, the flanges may be eliminated and the tabs 8 made to extend directly from the walls of the container. The length and configuration of the flanges 7 and tabs 8 may be varied as desired. The material by which they are constituted should have a certain amount of flexibility so that they may be bent to engage the surface of the tube, but should also be sufiiciently rigid so that they may adequately support the tube.
It may be seen that a simple construction is provided which houses the chassis of the electronic device and further provides a means for supporting the picture tube 12, which means is formed partially by a portion of the cabinet itself. The number of steps required to assemble the picture tube in the cabinet are reduced to a minimum and adequate support is provided. By making the flanges 7 of any desired width, tubes of varying dimensions can be accommodated in a cabinet of given dimensions. Also, if desired, stops may be provided on the ends of the tabs 8 to limit the forward motion of the tube. If desired, apertures 16 may be provided in suitable walls of the cabinet for ventilation purposes or for providing accms for the loudspeakers forming a part of the device.
While we have described a particular embodiment of our invention, other applications and arrangements will readily occur to those skilled in the art. We do not, therefore, desire our invention to be limited to the specific construction illustrated and described, and we intend by the accompanying claims to cover all modifications within the spirit and scope of our invention.
