Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a device for fixing a cathode ray tube to a decorative panel, and particularly to a cathode ray tube fixing device that is effective in reducing the number of parts and improving work performance.

[Technical background of the invention]

Conventionally, when fixing a cathode ray tube to a decorative panel, a plurality of poles provided on the back of the decorative panel press the side edges of the cathode ray tube by inserting elastic padding members, and the friction force prevents play. It was fixed without arising. At this time, prepare several types of padding members of different sizes to prevent gaps between the periphery of the cathode ray tube and the poles of the decorative panel, which may occur due to variations in the thickness of the tension band attached to the periphery of the cathode ray tube. One of several types was selected and used depending on how wide or narrow the area was. Therefore, since a plurality of types of stuffing members are prepared, it is not only difficult to reduce assembly and manufacturing costs, but also the inventory management of parts becomes complicated and difficult.

[Means for solving problems]

The present invention solves the problems of the prior art, and provides a cathode ray tube fixing device that significantly reduces the number of parts, reduces assembly manufacturing costs, and facilitates inventory management of parts. It is something to do.

According to the present invention, by making the wall thickness of a single filling member different in the radial direction, when fixing a cathode ray tube, it is possible to select the optimal wall thickness by changing the insertion direction of the filling member. . This makes it possible to reduce the number of types of stuffing members to at least 1/4, and the above-mentioned problems can be solved.

〔Example〕

An embodiment of the present invention shown in FIGS. 1 to 3 will be described below.

In FIG. 1, 1 is a cathode ray tube to be fixed, and 2 is a decorative panel attached to the front of the cathode ray tube 1. A tension band 3 is attached to the side circumferential surface of the cathode ray tube 1, and a plurality of (eight in the figure) poles 4 are installed on the back side of the decorative panel 2. This pole 4 is preferably integrally molded with the decorative panel 2 from plastic.

The cathode ray tube is fixed to the decorative panel by screwing fixing tools provided at its four corners into screw holes provided at the four corners of the decorative panel 2.

As shown in FIG. 2, when the cathode ray tube 1 is attached to the decorative panel 2, a gap G is created between the side peripheral edge of the cathode ray tube and the pole 4, but a filling member made of an elastic material is used to fill this gap G. 5
(FIG. 3) is inserted into the pole 4. Therefore, the stuffing member 5 has a through hole 6 having a cross-sectional shape similar to that of the pole 4 (square in the figure), so that the stuffing member 5 can be firmly fixed to the pole 4 when inserted. The cross-sectional area of the through hole 6 is smaller than the cross-sectional area of the pole 4. The wall thicknesses H1 to H4 of each side of the stuffing member 5 are different as shown in FIG.
Set at 2, 3 and 4 mm. Gap G
is not necessarily constant and may be slightly wider or narrower due to manufacturing errors when the decorative panel 2 is manufactured by integral molding or variations in the thickness of the tension band 3 between manufacturers. There is also. In this invention, even if the gap G varies between wide and narrow, the filling member 5
By appropriately selecting one of the four types of wall thicknesses prepared, it is possible to firmly fill the gap G, that is, to firmly fix the cathode ray tube 1 to the decorative panel 2.

In the present embodiment, the pole 4 is a square pole, but it is not limited to the four corners, but may have a shape that prevents the padding member 5 from easily rotating relative to the pole, that is, a polygon (for example, from a triangle to an octagon). Good to have. The more polygonal the shape, the greater the variety of wall thicknesses, and the greater the ability to respond to various gap changes. The length of the padding member 5 in the vertical direction may be approximately the vertical width of the side periphery of the cathode ray tube 1 as shown in FIG. 2, but it may also be as long as the entire length of the pole 4.

[Effect of idea]

According to the present invention, gaps of various sizes can be handled with a single filling member having multiple types of wall thickness, so there is no need to prepare multiple types of filling members, reducing assembly and manufacturing costs. Not only is this possible, but it also has excellent effects such as simplifying parts inventory management.
