Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention is a speaker box made of wood or plastic, in which no gap is created by the constituent materials due to water-containing strain or uneven heat distortion of the material. It is about.

<Prior Art> Conventionally, a multi-way speaker is often used in this type of speaker box, so that the speakers are often arranged vertically long and the boxes are also vertically arranged. for that reason,
Many of the materials that make up the box, such as plastic plates, have a flat outer shape and long dimensions. When assembled in such a box, gaps or distortions were formed in the seams of the constituent materials, and the seams of the material joints often impaired the overall commercial value of the eyes.

<Problems to be solved by the invention> Therefore, in the conventional speaker box of this type, another corner metal fitting must be added to the corner portion of the speaker box constituent material of the cabinet to be used for keeping airtightness. It was

In addition, when the speaker box is viewed from the front, there is a problem in terms of external design due to the difference in grain between the vertical plate and the horizontal plate.

Therefore, in order to solve the conventional problems, an object of the present invention is to fix and strengthen the side edge of the box along the long side of the speaker baffle by a vertically provided locking and fixing projection.

<Means for Solving the Problems> The structure of the present invention for achieving the object will be described with reference to FIGS. 1 to 5 corresponding to the embodiments.
Forming eaves-shaped locking parts (9), (9) on the locking and fixing projections (8), (8) standing on the baffle plate (4) that fixed the speaker,
The baffle plate (4) is clamped and fixed by engaging with the notches (3a) and (3b) of the frame plate (2) and sliding it.

<Operation> Since the present invention has such a structure, the eaves-like engagement formed on the locking and fixing projections (8) and (8) erected on the baffle plate (4) to which the speaker is fixed. Since the box frame plate (2) is squeezed by the inclined surfaces of the stoppers (9), (9), the gap between the baffle plate (4) and the box frame plate (2) can be kept tightly pressed. is there.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

1 to 5 are views showing a first embodiment of the present invention, in which (1) is a speaker box made of wood or plastic, which is composed of frame plates (2) ... Notches (3a) and (3a) are provided approximately in the middle of 2) and (2), respectively. Reference numeral (4) is a wooden or plastic baffle plate, and the speakers (5) are fixed to the baffle plate (4) with screws or the like.

(8) and (8) are erected on the wooden baffle plate (4) or the plastic baffle plate (4), and the cutouts (3) of the left and right frame plates (2) and (2)
It is a protrusion for locking and fixing a) and (3b).

The notches (3a), (3b) provided on the frame plates (2), (2) at positions where the both locking and fixing projections (8), (8) face each other with the baffle plate (4) interposed therebetween.
It is locked and fixed to.

The sectional views of FIGS. 2 to 5 are a longitudinal sectional view and a lateral sectional view of an essential part of the present invention shown in FIG. 1, and FIG. 2 is a projection (4) of the baffle plate (4) of FIG. 8) to the speaker box (1) frame plate (2)
It shows that it will be inserted into the notch part (3a) of, and after inserting the protrusion (8) into the notch (3a), shift the baffle plate (4) upward,
The speaker box (1) and the baffle plate (4) are aligned with each other at the top and bottom, and the catches (11) at the four corners are fitted and fastened with the screws (12).

FIG. 3 shows the eaves-like locking portion (9) of the protrusion (8) of the baffle plate (4),
It is shown that the inclined part of (9) is displaced from the inner surface of the frame plate (2) and the frame plate (2) is joined to the baffle plate (4).

FIG. 5 is a diagram in which the protective net (13) is further inserted into the catch holder (25) and fixed to the baffle plate (4).

Thus, as shown in the above figures, the eaves-shaped locking portion (9) of the projection (8) of the baffle plate (4) is displaced in the direction of displacement when the inner surface of the frame plate (2) is displaced. By forming the plate so that the thickness in the opposite direction becomes thicker so as to approach the frame plate (2) so as to move away from the frame plate (2), it is possible to temporarily fix the frame plate (2).

6 and 7 show an application example of the present invention, in which the eaves-like locking portions (9), (9) are locked from the inside of the frame plate (2).
Same as the embodiment, but if the mounting part of the speaker (5) becomes long, the number of notches (3a) and protrusions (8) of the frame plate (2) of the speaker box (1) is increased. By doing so, it is possible to increase the strength, and as shown in the drawing, the eaves-like locking portion (9),
After engaging the notch (3a) and (3b) of the speaker box (1) with the speaker (9), lift the baffle plate (4) and lock the protrusion (16) with the upper frame plate (2). The fixing plate (14) attached to the lower inner surface of the plate (4) can be fixed to the lower frame of the speaker box (1) with screws (15), (15) or the like to strengthen a long box.

Although the embodiments considered to be typical of the present invention have been described above, the present invention is not necessarily limited to only the structures of these embodiments, and the constitutional requirements referred to in the present invention and the purpose referred to in the present invention can be obtained. The present invention can be carried out with appropriate modifications within the scope of achieving the following effects.

<Effects of the Invention> As is apparent from the above description, the present invention is strong because the cross-sectional inclined surface of the locking portion of the baffle plate engages at the strong joint of the inclined surface of the front edge on the box side. Therefore, it is possible to expect a practically significant effect of binding to the above.
