Description

[Detailed Description of the Invention] The present invention relates to a box body for audio equipment having wooden side panels.

For example, as shown in FIG. 1, a box body for audio equipment such as an integrated amplifier or a tuner is made up of a metal chassis 1, a metal decorative front panel 2, a metal top plate 3, and a wooden side plate 4. For example, each wooden side plate 4 is integrally bonded to the outer surface of each side plate 3a of the top plate 3 with an adhesive, and then each side plate 3a of the top plate 3 is assembled.
are applied to each side plate 1a at the bottom of the chassis 1, and fixed by screwing screws 5 to each side plate 1a of the chassis 1 from the outer surface of each side plate 4 through each side plate 3a of the top plate 3. Ta.

It is assumed that a metal decorative front panel 2 is screwed onto the front surface of the chassis 1 in advance.

As mentioned above, each side plate 4 is screwed together with the top plate 3 to the chassis 1. In this case, if there is a difference in the dimensions of the front panel 2 and the top plate 3, each side plate 4 of the front panel 2 A gap is created between the side end surface and the notched vertical groove 4a on the inner side of the front end surface of each side plate 4, which significantly impairs the appearance and reduces the commercial value.

The front panel 2. The variation in dimensions between the front panel 2 and the top plate 3 makes it difficult to mold the front panel 2 and the top plate 3, and has been a bottleneck in assembling this type of box body.

The present invention is intended to solve the conventional bottlenecks as described above, and an embodiment thereof will be described below with reference to FIGS. 2 and 3.

As shown in FIGS. 2 and 3, a horizontal groove 4b extending over the entire width of the side plate 4 is provided at the upper part of the inner surface of each wooden side plate 4.
A locking protrusion 6a is provided at the upper end to be inserted into b.
An elastic fixing fitting 6 having an inverted letter shape with a screw insertion hole 6b on the plate surface is inserted into the inner surface of each side plate 4, and the locking protrusion 6a at the upper end of the fixing fitting 6 is inserted into the horizontal groove 4b. Secure it with a neck tie.

In this case, it is desirable that there be as little gap as possible between the tip of the locking protrusion 6a at the upper end of the fixture 6 and the inner wall surface of the lateral groove 4b.

Further, it is sufficient to attach the fixing fittings 6 only at the front portion of the upper inner surface of each side plate 4, but they may also be attached at the rear.

Then, each side plate 4 is fixed to each side plate 1a at the lower part of the metal chassis 1, which is a metal decorative front panel 2, with screws 5 on the front side, and the inner side of the front end surface of each side plate 4 is Each side end of the front panel 2 is fitted into the notched vertical groove 4a (see FIG. 4).

Next, insert the downward right-angled bent pieces 3a on both sides of the metal top plate 3 into the horizontal grooves 4b of each side plate 4 from the rear of the side plate 4 to the tips of the locking protrusions 6a at the upper end of the fixture 6 and the horizontal grooves 4b.
(See Figures 3 and 4).

The height of the downward right-angled bent pieces 3a on both sides of the top plate 3 is set to be slightly lower than the height of the horizontal grooves 4b on each side plate 4, and the downward right-angled bent pieces 3a on both sides
The width between the outer surfaces of the side plates 4 attached to the chassis 1 should be smaller than the width between the inner wall surfaces of the horizontal grooves 4b of each side plate 4. Piece 3
Consideration should be given to elastically colliding with a.

Further, the tip edge of the locking protrusion 6a at the upper end of the fixing metal fitting 6 is shaped into a circular arc as shown in FIG. The downward right-angled bent pieces 3a on both sides of the top plate 3, which are fitted into the horizontal grooves 4b of each side plate 4 in this way, are held in place by the locking protrusions at their upper ends due to the elasticity of each fixing metal fitting 6 itself. Since it elastically collides with the piece 6a, each of the side plates 4 is pulled inwardly toward each other, so that the notch vertical groove 4a on the inside of the front end surface of each side plate 4 and each side end surface of the front panel 2 are connected. It can be made to fit completely, and the top plate 3 can be placed between the side plates 4.
can be installed smoothly.

In addition, each side plate 4 is fitted into the horizontal groove 4b of each side plate 4 by inserting each downward right-angled bent piece 3a of the top plate 3 as described above, and after installing the top plate 3 between the side plates 4 in advance, each side plate 4 is inserted into the side plate 4 of the chassis 1. It may be fixed to each side plate 1a in the lower part with screws 5, respectively.

As described above, according to the present invention, the notch longitudinal grooves 4a on the inner side of the front end surface of each side plate 4 are fitted to each side end of the decorative front panel 2 attached to the front surface of the chassis 1, and Each side plate 4 is connected to each side plate 1a at the bottom of the chassis 1.
Since each downwardly bent right-angled piece 3a on both sides of the top plate 3 can be inserted between the screwed horizontal grooves 4b of each side plate 4 with a required insertion gap, both sides can be screwed together. Even if there is slight variation in the width between the outer surfaces of the downward-facing right-angled new piece 3a, the top plate 3 can be inserted with plenty of room between the horizontal grooves 4b of each side plate 4, and it can be fixed to the inner surface of each side plate 4. Since the locking protrusion 6a at the upper end of the elastic fixing fitting 6 is elastically abutted against the downward right-angled bent piece 3a, each side plate 4 is pulled inwardly, and therefore each side plate 4 The vertical notch 4a on the inner side of the front end surface can be brought into perfect contact with each side end surface of the front panel 2, and the top plate 3 can be smoothly installed between the side plates 4.

In addition, since there is no need to use adhesive to bond the side panels of the top plate to each side plate as in the past, the troublesome work and drying time required for bonding can be saved, which contributes to improved productivity. This eliminates the need for long side panels on both sides, which can also contribute to reducing material costs.
