としては次のようなものが考えられる。 FIG. 1 shows a conventional chassis for audio equipment, such as a stereo tuner.
For example, a pair of bridging members 3 and 4 made of a sheet metal are spanned between the pair of side plates 2 of the frame 1, and bent portions 5a for attaching side plates provided at both ends of the bridging members 3 and 4, 5b is attached to the side plate 2. These bridging members 3 and 4 are attached for the purpose of reinforcing the frame 1, but normally, for example, a pair of bent parts 6a and 6b for attaching parts are provided on the bridging members 3 and 4, respectively. These bent parts 6
Equipment parts 7 such as printed circuit boards are mounted on a and 6b. Such bridging members 3, 4
Possible examples include the following:

このため、架橋部材3,4の長手方向の両端部付

の設計に大きな制約を受けてしまうことになる。
以上のようなことを勘案すれば明らかなように、
本例の如き架橋部材3,4はどのような場合でも
利用できるとは限らないという問題点がある。Comparative Example 1 Using bridging members 3 and 4 of the same shape manufactured by a common mold, these bridging members 3 and 4 were oriented in opposite directions (point symmetrical) to each other as shown in FIGS. 1 and 2. Attach it to the side plate 2 of the frame 1 so that the In this case, although it is possible to reduce the cost of the chassis because the mold can be shared, the bent parts 6a and 6b for attaching parts are arranged at staggered positions without facing each other. So,
It becomes difficult to install equipment parts such as printed circuit boards. Therefore, in order to eliminate this inconvenience, if the bent parts 6a and 6b for attaching parts are provided at predetermined positions as shown by chain lines in FIG. 2, these bent parts 5 and 6 can be arranged opposite to each other. However,
In this case, the mounting position of the device component 7 is limited to the central portion of the bridge members 3 and 4 in the longitudinal direction.
For this reason, the equipment components 7 cannot be placed near both ends of the bridge members 3 and 4 in the longitudinal direction, and the design of the equipment is severely restricted.
Considering the above, it is clear that
There is a problem in that the bridging members 3 and 4 as in this example cannot be used in all cases.

高くなるという製作上の大きな問題点がある。Comparative Example 2 As shown in Fig. 3, a pair of bridging members 3 and 4 are bent so as to have mirror symmetry (line symmetry), and the bridging members are made with the bent parts 6a and 6b for attaching parts facing each other. 3 and 4 are attached to the side plate 2 of the frame body 1. In this case, the device parts are bent at the bent portions 6a, 6.
Although it is very convenient for mounting on the mold, it has the disadvantage that it is difficult to share the same mold because the punching burrs and the bending directions are opposite. That is, the bridging members 3, 4
When manufacturing, the punching process can be performed using a common mold, but the bending process for the side plate attachment bending parts 5a, 5b and the parts attachment bending parts 6a, 6b can be performed using separate molds. must be done. Therefore, there is a major manufacturing problem in that the manufacturing cost of the bridge members 3 and 4 increases.

The present invention relates to a chassis in which side plate attachment bent portions of the first and second bridging members are respectively attached to a pair of side plates of the frame body in a state where they are arranged opposite to each other. With this configuration, it is possible to very easily attach equipment components to the parts attachment bends of the bridge member, and the internal design has a high degree of freedom without restricting the design of the equipment. This makes it possible to design the structure and provide an inexpensive chassis.

11, and the frame body 9 is composed of a pair of side plates 12 facing each other and having an L-shaped cross section, and a rear plate 13 connecting the pair of side plates 12. Further, the bridging members 10 and 11 are made of a single sheet metal, and the substrate portions 14 and 1 are approximately L-shaped in cross section.
5 each. And the substrate part 14,1
The vertical parts 16 and 17 of 5 have side plate mounting bent parts 1 bent at almost right angles at both ends in the longitudinal direction.
8 and 19 are provided, respectively. Furthermore, a pair of bent parts 20 and 21 for attaching parts, for example, are provided at the upper edges of the vertical parts 16 and 17 in the longitudinally intermediate parts thereof. Note that bridging member 1
The bent part 20 for attaching parts 0 is parallel to the horizontal part 23 of the substrate part 14 and is bent in the same direction, and the bent part 21 for attaching parts of the other bridging member 11 is Horizontal portion 24 of substrate portion 15
It is parallel to and bent in the opposite direction. Therefore, the pair of bridging members 10,1
In No. 1, the bending members 20 and 21 for attaching parts are configured so that the bending directions are opposite to each other, and the other shapes (configurations) are the same.

る。 Describing the manufacturing procedure of the bridge members 10 and 11, first, a sheet metal 30 having a shape as shown in FIG. 6 is punched out using a common punching die. Then, this sheet metal 30 is bent at the bending lines 30a, 30b, 30c (see FIG. 6) using a common bending die, thereby forming the side plate mounting bent portions 18, 19. and horizontal part 23,2
4 at the same time. After that, this sheet metal 30
The bending line 30 is made in a separate process using a separate mold.
d and 30e (see Figure 6) are bent.
That is, when manufacturing the bridging member 10, the bent part 20 for attaching parts is bent in the same direction as the horizontal part 23, and when manufacturing the bridging member 11, the bent part 2 is bent in the same direction as the horizontal part 23.
1 is bent in the opposite direction to the horizontal portion 24.

いる。 Further, as shown in FIGS. 4 to 6, screw holes 26 are provided in the bent portions 18, 19 and 20, 21, respectively. and bridging member 10,
11 is stretched substantially parallel to each other between the side plates 12 of the frame body 9, and side plate mounting bent portions 18 and 19 at both ends thereof are screwed to the side plates 12 by set screws 27. As mentioned above, since only the bending directions of the bent parts 20 and 21 for attaching parts are opposite to each other, the bridging members 10 and 11
When attached to the side plates 12 of the frame body 9 as described above, the bent portions 20 and 21 are arranged on the same plane and facing each other (see FIG. 5). And these bent parts 2
Equipment parts (not shown) such as a printed circuit board are fixed onto the parts 0 and 21 using set screws or the like.

るという利点もある。 According to the chassis 8 configured in this way, the frame body 9 can be reinforced by the pair of bridging members 10 and 11, and the bent parts 20 and 21 for attaching parts of the bridging members 10 and 11 are arranged on the same plane. Since they are arranged facing each other, equipment parts 7 such as printed circuit boards can be attached very easily. Moreover, since the positions of the component mounting bending parts 20 and 21 can be changed arbitrarily, the mounting positions of the device parts can be changed as appropriate, and the internal structure of the device can be designed with a high degree of freedom. In addition, despite having such advantages, when manufacturing the bridge members 10 and 11, punching processing and bent parts 20 for attaching parts,
Since all the bending processes other than 21 can be performed using a common mold, there is an advantage that the manufacturing cost of the bridge members 10, 11 and, in turn, the chassis 8 can be kept low.

く抑えることが可能である。 As described above, the present invention provides the first and second bridging members, which are constructed in such a manner that only the bending directions of the bent portions for attaching parts are opposite to each other, and the other shapes are identical to each other, between both side plates of the frame body. The first and second parts mounting bent parts are arranged to face each other on the same plane. Therefore, according to the chassis of the present invention, the frame can be reinforced by the first and second bridging members, and equipment parts such as printed circuit boards can be attached to the bent parts for mounting parts of the first and second bridging members. It can be installed very easily and the device structure can be designed with a very high degree of freedom. Moreover, since the only difference between the first and second bridging members is the bending direction of the bent part for attaching parts, the punching and bending processes other than this bending process can be performed using a common mold. This makes it possible to reduce the manufacturing cost of the bridge member and thus the chassis.
