Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cabinet manufacturing method applied to electronic equipment and the like. Specifically, the cabinet components that make up the cabinet are integrally molded at the hinge portion, and after the components are attached, the cabinet components are rotated and assembled to facilitate the internal components even if the cabinet has a curved surface. The present invention relates to a method of manufacturing an attachable cabinet.

[0002]

2. Description of the Related Art In portable electronic equipment such as a CD radio cassette recorder, the number of curved surfaces used in its cabinet is increasing due to the recent diversification of designs.

FIG. 7 shows the shape of the front cabinet 11 which constitutes the main body of such a CD radio cassette recorder. Outer surface side 11a of this front cabinet 11
Is curved for aesthetic purposes.

When assembling this CD radio cassette recorder, the speaker 12 is attached to the inner surface side 11b of the front front cabinet 11 and then combined with a rear cabinet (not shown) to form a main body.

[0005]

By the way, in the front cabinet 11 shown in FIG. 7, a curved surface can be formed relatively freely on the cavity side (outer surface side 11a) for the convenience of molding, but on the core side ( The shape of the inner surface side 11b) is limited by the movable side drawing direction of the mold. That is, on the inner surface side 11b of the front cabinet 11, the speaker mounting boss 13 is formed vertically so as to coincide with the drawing direction (arrow direction in FIG. 7) of the mold (core). On the other hand, the mounting direction of the speaker 12 is set obliquely in relation to the design, and does not coincide with the standing direction of the speaker mounting boss 13.

Therefore, conventionally, as shown in FIG. 8, a speaker 12 is supported in a predetermined mounting direction by using a mounting bracket 15, and the mounting bracket 15 is fixed to a speaker mounting boss 13 with a screw 17.

However, according to this method, the speaker 1 is assembled at the time of assembly.
Since the arrangement of No. 2 becomes unstable, it is necessary to fasten the screw 17 downward while diagonally supporting the speaker 12, and there is a problem that the assembly work becomes complicated. In addition, since the mounting bracket 15 for supporting the speaker 12 is separately required, the number of parts is increased and the cost is increased.

Therefore, the present invention has been made to solve the above-mentioned problems, and even when a cabinet having a curved surface or the like is manufactured, the internal parts can be easily attached and the internal parts can be supported. The present invention proposes a cabinet that does not require a separate member and a manufacturing method thereof.

[0009]

In order to solve the above problems, in the invention according to claim 1, there is provided a cabinet manufacturing method, wherein at least two cabinets for mounting at least two cabinets are provided. The body is connected by a hinge part, and the component mounting portion for mounting and fixing the component inside the cabinet structure is molded in a substantially vertical state, and the component is mounted to the component mounting portion of the cabinet structure, and the cabinet is mounted. It is characterized in that the structure is rotated around a hinge portion as a fulcrum to assemble a predetermined shape.

According to another aspect of the present invention, a cabinet structure having a component mounting portion for mounting a component from a predetermined direction, a hinge portion for rotatably connecting a plurality of cabinet components, and a cabinet for each other. It is characterized in that it is composed of a fixing portion for connecting the structural body, and is integrally formed by fixing the fixing portion.

When assembling this cabinet,
A component is attached to the component mounting portion of the cabinet assembly, and the cabinet assembly is rotated about the hinge to assemble a predetermined shape.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a cabinet manufacturing method according to the present invention will be described in detail with reference to the drawings.
The speaker section 20 of the CD radio cassette recorder 1 shown in FIG. 1 is formed in a cylindrical shape, and an operating section 18 on which various switches, a cassette housing section 7 and a CD reproducing section 8 are arranged is provided on the upper side thereof. In this CD radio cassette recorder 1, six speakers 12 are attached inside the punching panel 9 over the entire circumference of the speaker unit 20.

As shown in FIG. 2, the speaker section 20 is constructed by combining three cabinets 21 to which the speakers 12 are attached. That is, one cabinet 21 corresponds to a portion obtained by dividing the entire circumference of the speaker unit 20 into three.

FIG. 3 shows a state in which the molded cabinet 21 is placed with its outer surface side facing downward. This cabinet 2
1 is two cabinet structures 21a, 2 of substantially the same shape
1b and the hinge part 22 which connects these. In the method of manufacturing the cabinet 21 according to the present invention, after the internal parts are attached to the cabinet 21, the cabinet components 21a and 21b are rotated by the hinge portion 22 to assemble a predetermined curved surface.

First, cabinet components 21a and 21b
Will be described. Cabinet structure 21a, 21b

The speaker mounting boss 25 is erected substantially vertically when the outer surfaces of the cabinet components 21a and 21b are placed downward. The standing direction corresponds to the drawing direction on the movable side of the mold. Further, the surfaces of the speaker mounting surfaces 29, 29 are formed so as to be orthogonal to the mold drawing direction.

Next, the hinge portion 22 will be described. Two hinge parts 22 are formed on the edges (inner edges 27, 27) of the cabinet components 21a, 21b that face each other. The hinge portion 22 is formed in a Z shape by a bent portion 22b that can be bent by elastic deformation and support portions 22a and 22a that connect the bent portion 22b and the cabinet constituents 21a and 21b.

The supporting portions 22a, 22a are opposed to each other and project at a position displaced by a predetermined distance. Bent part 22b
Is integrally connected to the support portions 22a, 22a, and is elongated along the inner edge portion 27 of the cabinet components 21a, 21b. The bent portion 22b is formed in a particularly thin plate shape so as to be bendable, and has a substantially U-shaped cross section in advance corresponding to the bending direction.

The hinge portion 22 is formed in a Z shape by the support portions 22a, 22a and the bent portion 22b because the cabinet 21 has a certain length from the connecting portion of the hinge portion 22 to the connecting portion. This is to prevent the hinge portion 22 from being bent by flexibly bending the hinge portion 22 even when it is formed of a relatively hard material.

Two trapezoidal meshing portions 35 are provided in the center of the inner edge portions 27, 27 of the cabinet components 21a, 21b so as to be staggered. The meshing portion 35 meshes with each other when the cabinet components 21a, 21b are rotated up to a predetermined angle with the hinge portion 22 as a fulcrum to connect the cabinet components 21a, 21b.

Further, a fixed portion 31 is formed at one end of the inner edge portion 27 of the one cabinet structure 21b, and the other cabinet structure 21a corresponding to the fixed portion 31 is formed.
A fixing plate portion 32 is formed at the end of the inner edge portion 27 of the.
