Description

[Detailed Description of the Invention] The present invention relates to a door of a control box or the like of a television receiver.

Conventionally, with this type of layer, a pattern is directly formed on the surface of the synthetic resin door by painting or hot stamping, or a metal plaque with a pre-printed pattern is attached to the above □ to create a decorative effect. I was trying to have it.

However, recently, as shown in Figure 1, a sound emitting net A is attached to the front of the speaker mounting part of the cabinet.
In order to create a sense of unity in design, it has become necessary to attach a similar net to the surface of door B.

When attaching a decorative woven fabric such as a net to a door, the end of the woven fabric must be folded back and glued to the back side of the square, and the folded portion must be hidden.

For this reason, it is necessary to attach a suitable backing plate to the back of the □ board to which the decorative woven fabric has been pasted. However, if this is done using screws or adhesives, the workability is poor and there is a possibility that the screw heads will There are disadvantages in that the adhesive is exposed on the back side of the door plate and the adhesive flows out from the edges, which impairs the aesthetic appearance.

Therefore, the present invention has been devised in consideration of such points, and the door of the present invention will be explained below with reference to FIGS. 2 to 7.

FIG. 2 is a perspective view showing the □ of the present invention removed from the control box of the main body of the device, and this door is composed of a □ board 1 and a decorative plate 2.

The door plate 1 is a synthetic resin molded product, as shown in Figure 2 and □ above.
As can be seen from FIG. 3, which shows the disassembled state of the control box 3, the recesses 4, 4 of the control box 3 are located on the outer surface of this door plate.
Support arms 5, 5 rotatably supported by the control box and a locking pawl 7 that engages with the notch 6 of the control box are integrally molded.

In addition, on the inner surface side of this door plate, there are a plurality of recesses 8 at the upper end,
A cylindrical protrusion 9 having a cylindrical protrusion 9 having a shape of 8... is located at the center, and an engagement protrusion 10 having an L-shaped cross section is located on a virtual circumference centered on the protrusion.
, 10... are molded.

On the other hand, the decorative plate 2 is made of synthetic resin with a decorative woven fabric 11 pasted on its outer surface, and the inner surface of the decorative plate 2 has a cylindrical protrusion 13 with radial ribs 12, 12... And protrusions 14, 14, . . . similar to those on the door plate side described above are formed.

Note that, as explained at the beginning, the ends of the woven fabric 11 are folded back to the back side of the decorative plate 2, and the folded portions are bonded to the edges of the decorative plate 2.

Next, the door plate 1 and the decorative plate 2 are combined to complete the door as described above.

That is, first, the cylindrical projection 13 on the decorative plate 2 side is fitted into the cylindrical projection 9 on the door plate 1 side, which is molded to have a slightly larger inner diameter than this.

At this time, the decorative plate 2 and the door plate 1 are shifted from each other as shown in FIG. 4, so in this state, as shown in FIG.・Door plate 1
The upper end of the cylindrical protrusion 9 rests on the upper end of the cylindrical protrusion 9, and the engaging protrusions 10, 10... on the door plate 1 side and the engaging protrusions 14 on the decorative plate 2 side
Each side of 14 faces each other.

Therefore, from this state, as shown in the opening of FIG. 5, the decorative plate 2 is moved in the direction of the arrow in FIG. Rotate.

Then, as shown in FIG.
0... and 14, 14... are engaged with each other, the ribs 12° 12... of the decorative plate 2 fit into the recesses 8, 8... of the cylindrical protrusion 9 of the door plate 1, As a result, the decorative plate 2 and the door plate 1 are firmly connected.

At that time, the engaging protrusions io, io... and 14, 14
. . , the central portion of which is slightly raised as shown in FIG. 6, the connection between the decorative panel 2 and the door panel 1 becomes even more solid.

In the embodiments shown in FIGS. 3 to 5, ribs 12, 12, . Although the recessed portions 8, 8, .

That is, in the one shown in FIG. 7, rectangular parallelepiped-shaped ribs is and is are provided as positioning protrusions, and these ribs form the spaces between reinforcing ribs 16, 16, . . . formed on the back side of the decorative plate 2. 17.17.

According to the present invention having the above-mentioned structure, it is possible to provide a door that is very easy to assemble and has an excellent appearance at a low cost.Moreover, a door plate can be used in common for doors with different patterns, colors, etc. Therefore, it is suitable as a control box for a television receiver, etc.
