The present invention relates to a cathode ray tube (CRT).
The present invention relates to a frame structure for maintaining a self-sustaining state.

[0002]

2. Description of the Related Art In video equipment such as a television receiver and a display monitor, a CRT constituting the video equipment is used.
As a means for holding the CRT, a configuration is generally used in which a CRT is housed in a front cabinet, attached and held.

[0003] Japanese Patent Application Laid-Open No. 11-266416 discloses a CRT.
A configuration has been proposed in which four divided frames corresponding to the four sides forming the outer periphery of the CRT are used to hold the CRT independently.

[0004]

In a configuration in which a CRT is housed in a front cabinet, it is necessary to design and produce a new front cabinet every time the appearance design changes. This has been a problem in terms of the production cost and the production period of a molding die and the like.

[0005] With the increase in the size of the television receiver, the problem of physical distribution such as transportation and storage has also become a problem.

Further, Japanese Patent Publication No. 11-266416 discloses a CR
Four frames corresponding to the four sides of T are required. Therefore, in this case, a new frame needs to be created each time the design changes. In addition, the holding structure of the CRT also has to be mounted via four side frames, which is complicated.

FIG. 7 is an exploded perspective view showing a conventional CRT holding device, and FIG. 8 shows an assembled state thereof.

[0008] The present invention has been made to solve the above problems, and has a CR
An object of the present invention is to provide a CRT holding device which can hold a CRT of an arbitrary size in a self-standing state by using only the lower side of T. Also, when recycling the CRT holding device,
This facilitates decomposition and improves the recycling rate.

[0009]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a frame fitted to the lower side of a CRT,
The frame is configured such that a tube surface portion (particularly, a rear tube surface portion) from the front to the rear of the CRT is in close contact with the CRT.

[0010] The frame is made of a magnesium alloy, an aluminum alloy, a zinc alloy or the like.

Further, a structure in which a cushioning material such as a sponge is interposed between the frame and the tube portion (particularly, the rear tube portion) of the CRT in close contact with each other.

Further, a metal fitting attached to a lower side of the CRT is screwed to the frame.

Further, the frame constitutes a holding device of the CRT, and a front panel is attached to a front side of the frame to improve an external design.

Further, a rear cover is attached to the rear side of the frame to improve the appearance design.

With the above structure, the holding device of the present invention has a CR
By using only the lower side of T, a CRT of an arbitrary size can be held in an independent state.

Further, in a CRT having the same shape, even if the external design changes, the use of a common member can reduce the cost and shorten the period for manufacturing the holding device.

Further, when recycling the CRT holding device, the CRT holding device can be easily disassembled and the recycling rate can be improved.
