Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a housing for accommodating and using a large number of box-shaped units.

[Prior art]

When housing a box-shaped unit with various electronic circuits mounted on it, a shelf-shaped chassis is generally used, and after housing the unit, the chassis is attached to a housing such as a rack or console. As a result, the structure becomes complicated and expensive, and when adding more units, it is necessary to add a chassis, resulting in disadvantages such as a lack of expandability.

As a countermeasure against this problem, a case structure has been proposed in which the units are connected vertically to the frame and then the frame is attached to the open surface of the outer case. This addition improves expandability, but when similar casings are installed side by side, conventionally, the front edge of the side plate of the outer casing is bent inward at a right angle. Therefore, if they are installed consecutively, the front edge of the side plate will be doubly interposed in the contact area between the outer casings, creating a gap between the units on the front of the casing, resulting in an aesthetically unsuitable defect. are doing.

[Summary of the idea]

The purpose of the present invention is to eliminate such drawbacks of the conventional method at once.The present invention forms a protrusion that protrudes vertically to the front and sides of the frame, and also connects the side plate of the outer casing to the side surface of the protrusion. By storing the protrusion so that the front side almost coincides with the rear step of the protrusion, no special gap is created in the continuous part even when the protrusion is connected. The present invention provides an extremely effective casing for continuous installation.

FIG. 6 is a horizontal cross-sectional view of a situation in which the casings shown in FIG.
The front edge 502 is accommodated in the rear side stepped portion 205B, and the front edge is hemmed. Even if the units are connected, the outer surfaces of the side plates 314B and 314 of the connected outer casing are in close contact with each other, and at the same time, the side surface 501B of the protruding portion 205A of the connected side frame 302B is in close contact with the side surface 501, and the side surface 501B of the unit 322 is in close contact. The gap _ds between the side end 504 of the front flange portion 503 and the flange portion 503B of the connected side unit 322B is approximately equal to the gap d between the side end 503 of the unit 322 in the same outer casing.

Note that since the stay 315 is interposed in the stepped portion 205B between the frames 302, it does not interfere with the protruding portions 205A of the frames 302 bringing the side surfaces 501 into close contact with each other.

Therefore, even if the casings are connected, the unit 32
The gap between 2 and 322B is the same as the others, and the apparent state of connection becomes unclear, making it appear as if it were an integrally formed casing, which is very aesthetically pleasing.

Furthermore, if the frame 302 is installed, if the unit 322 is to be added as the number of guest rooms increases, the unit 322 can be installed instead of a blank panel, or the outer case 301
Since it is only necessary to extend the casings by connecting them laterally, a casing with a simple and inexpensive structure and excellent expandability can be obtained.

However, since the outer casing 301 shown in FIG.
3 is inclined in elevation, but these can be selected arbitrarily according to the installation conditions, and the required number of frames 302 to be accommodated and the required number of units 322 to be accommodated in the frames 302 are also determined according to the situation. Bye.

Further, the bent shape of the protrusion 205A can be selected arbitrarily, and the bent shape of the front edge of the side plate 314 is
Depending on the protrusion height and shape of the protrusion 205A, the protrusion 205A may be bent into a U-shape, a U-shape, or the like, instead of being completely flat.

Note that the unit 32 accommodated in the frame 302
2 is not limited to the one shown in FIG. 1, but may be box-shaped and have screw holes on both sides, and can be modified in various ways, such as being able to accommodate various box-shaped units.
