Description

[Detailed Description of the Invention] This invention relates to an improvement in the cabinet structure that is composed of three pieces: a front cover, a top cover, and a bottom cover.

For example, the cabinet structure of an electric device such as a portable television receiver is assembled from three pieces: a front cover, a top cover, and a bottom cover, and the following fitting methods are known.

One of them is to provide a hole in the front lid, provide projections on the top and bottom lids, and fit the projections into the holes to join the lids together.

However, when using this method, if the top and bottom lids are deformed, a step may be created at the fitting part, and if a synthetic resin lid is used, a wavy deformation may be caused at the fitting part. Therefore, it is not possible to adjust the appearance.

The other method is to fix a mounting bracket to the front cover and press down the top cover and bottom cover with screws, but this method inevitably increases the number of parts.

This idea was made in view of the above circumstances, and in a cabinet structure consisting of three pieces: a front cover, a top cover, and a bottom cover, the number of parts can be reduced by providing at least ribs and protrusions on the top cover. To provide a cabinet structure that eliminates poor appearance when fitted without increasing the appearance and also increases strength.

Hereinafter, this invention will be explained in detail based on an illustrated embodiment.

Figure 1 shows a side view of the cabinet structure of a portable television receiver, with a front cover 1, a top cover 2,
The three pieces of the bottom cover 3 are shown joined together.

Among these pieces, the front cover 1 has a fitting hole 4 at its edge, as shown in FIGS. 2 and 5.

Further, the upper lid 2 is provided with a restraining rib 6 along the lower surface near the edge, and a protrusion 5 that fits into the hole 4 is provided at a position closer to the back of the rib 6.

Further, the bottom cover 3 is provided with a protrusion 7 on the upper surface near the edge thereof, which fits into the hole 4.

However, although not shown in the drawings, this bottom cover 3 may also be provided with a restraining rib at a position in front of the protrusion 7.

Now, in order to assemble the cabinet structure from the above-mentioned pieces, the following fitting procedure may be followed.

First, the hole 4 of the front cover 1 is fitted into the protrusion 7 of the bottom cover 3 (FIG. 3).

Next, the top cover 2 is aligned above the front cover 1 at a certain angle.

In this case, since the protrusion 5 of the top cover 2 is located further back than the holding rib 6, the holding rib 6 fits into the edge of the front cover 1 first.

Therefore, if the top cover 2 is further rotated in the direction of the arrow shown in the figure, the top cover 2 and the front cover 1 will be completely fitted together (FIG. 4).

As mentioned above, the front cover 1 and the bottom cover 3 can be fitted together using the holes 4, protrusions 5, and ribs 6, like the front cover 1 and the top cover 2, without the need for any mounting hardware. Can be assembled.

In addition, the top cover 2 and the bottom cover 3 are not provided with protrusions 5 or ribs 6, and are assembled with screws in the conventional manner on the part that constitutes the back side of the casing to form the casing. be.

As is clear from the above, in this invention, ribs and protrusions are provided at least near the edges of the top lid, so that even if the top lid etc. is deformed, the formation of wavy deformation or steps can be avoided. It can be prevented and the appearance can be improved.

Especially in the case of a TV, because the image is viewed from the front, emphasis is placed on the cabinet structure and the appearance of the front and top surfaces. According to this idea, the front cover and the top cover can be placed in a straight line, without any difference in level! Since fitting can be performed without deforming P, it is possible to provide a cabinet structure that exactly meets such requirements.

Furthermore, since this invention has a structure that does not require any fittings or the like to fit the front cover and the top cover, the number of parts does not increase, and combined with the simple structure, it is economically advantageous.

The combination of ribs and protrusions means that the strength of the mating part is improved, making it particularly suitable for mating lid bodies that are thin and easily deformed. The cabinet structure is resistant to deformation or wobbling even when subjected to impact.

Therefore, this invention makes a significant practical contribution not only to the casing of a television receiver, but also to the aesthetics, strength, and manufacturing process of a three-piece removable cabinet structure.
