DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below. FIG. 1 is a horizontal sectional view showing a first embodiment of a vertical frame according to the present invention, and has a hollow structure formed by bending and forming a metal plate as a whole. However, the hollow structure is not limited to a complete hollow body, but may be a structure in which a part of the molding surface is cut. In FIG. 1, reference numeral 10 denotes a seal portion which is a U-shaped curved hollow outer edge portion which comes into contact with the back surface of the front door 1 via a packing, and has a first molding side 11 and a second molding side 12 from its base. The third molding side 13, the fourth molding side 14, the fifth molding side 15, the sixth molding side 16, the seventh molding side 17, and the eighth molding side 18 are sequentially formed. In this embodiment, the molding sides except the seventh molding side 17 are bent at right angles to each other.

[0008] Of these molding sides, the second molding side 12 is a side panel contact side that contacts the side panel 2, and FIG.
Is located in the upper left corner of the cabinet for storing electric and electronic equipment. As shown in the figure, the third to eighth molding sides (except for the seventh molding side 17) are each formed with a device mounting hole 4.

The fifth molding side 15 is a first equipment mounting side parallel to the front door 1 according to the first aspect. A device mounting rail or the like is mounted using the first device mounting side.

[0010] The third molding side 13 is the connecting metal fitting side described in the first aspect. The third molding side 13 is parallel to the first device mounting side (fifth molding side 15) and located at a position closer to the front door 1 than the first device mounting side. Further, the outer end is connected to the second molding side 12 which is the side panel contact side. On the side opposite to the front door 1 of the connecting metal fitting side 13, a connecting metal fitting space 20 is formed as shown in the figure. As shown in FIGS. 2 and 3, the connecting fitting 5 is mounted in the connecting fitting mounting space 20. Claim 2
As described in (1), since the connecting fitting mounting portion provided with the connecting fitting mounting side 13 is hollow, mechanical strength can be increased, and strong connection can be achieved.

[0011] The fourth molding side 14 is the second molding side according to claim 3.
This is the equipment mounting side. The fourth forming side 14 is perpendicular to the connecting bracket mounting side 13 and the first device mounting side 15, and a device mounting rail or the like is mounted similarly to the first device mounting side 15.

[0012] The sixth molding side 16 is the third molding side according to claim 4.
This is the equipment mounting side. This third device mounting side 16 is
Are parallel to the equipment mounting side 14, and a device mounting rail or the like is mounted. As described above, since the vertical frame of the present embodiment has many device mounting sides, various internal devices can be mounted.

FIG. 2 is a horizontal sectional view showing a structure in which the vertical frames shown in FIG. 1 are connected to each other. As shown in the drawing, the plate-shaped connecting metal member 5 is fixed by the bolt 21 using the device mounting hole 4 formed on the connecting metal member mounting side (third molding side 13) of both vertical frames, so that the adjacent vertical members are fixed. The frames can be firmly connected. In this state, the connection fitting 5 is completely contained in the connection fitting space 20, so that the connection fitting 5 does not protrude inward from the first device mounting side 15. Therefore, devices such as devices and cables arranged between the cabinets as before,
The hands during the operation do not get caught, and the workability of device installation and cable wiring can be improved.

FIG. 3 is a horizontal cross-sectional view showing a structure in which adjacent vertical frames are connected to each other by using an L-shaped connection fitting 5. As shown, in this case, one side 51 of the connection fitting 5
By hooking the hook 52 projecting from the hole in the connection fitting mounting side (third molding side 13), and connecting the other sides 53 of the connection fitting 5 with the bolts 22, both the vertical frames are firmly connected. ing. In this case, the end of the side 53 of the L-shaped connection fitting 5 protrudes from the connection fitting installation space 20, but the connection fitting installation space 20 shown in FIG.
The amount of protrusion is greatly reduced compared to the conventional without,
The workability of equipment installation and cable wiring is improved.

The connecting metal fittings 5 are mounted on the upper and lower parts of the vertical frame, and the other parts of the connecting metal mounting side 13 are not used. It can also be used as a device mounting side.

What has been described in the above embodiment is only the relationship between the molding sides. For example, the second molding side 12
The third molding side 13 is directly connected to the third molding side 13, but may be indirectly connected to an oblique or concave additional connection side. What is important is that the above-described positional relationship exists, and the present invention is not limited to a configuration in which each molding side is directly connected.

4 to 8 show another embodiment of the present invention. In each drawing, the corner is located at the upper left corner as in FIG. 1, and the same numbers are given to the molding sides corresponding to the molding sides in FIG. 1. Note that the position of the device mounting hole 4 is represented by a center line. The vertical frame of any of the embodiments has the sealing portion 1
0, second forming side 12 (side panel contact side), third forming side 13 (connecting metal fitting side), fourth forming side 14 (second device mounting side), fifth forming side 15 (first Equipment mounting side), 6th
The provision of the molding side 16 (third device mounting side) is the same as that of FIG.
The same applies to the case where Since the method of use and the function and effect are common, the description will not be repeated.

[0018]

As described above, according to the first aspect of the present invention, when connecting a plurality of cabinets, a portion of the connecting fitting used to connect adjacent vertical frames from the vertical frame. This makes it easier to install equipment and connect cables between connected cabinets. Further, according to the second aspect of the present invention, the connecting fitting mounting portion becomes strong, and a heavy electric / electronic device storage cabinet can be connected firmly. Claim 3,
According to the fourth and fifth aspects of the present invention, the number of device mounting sides increases, so that various internal devices can be easily mounted on the vertical frame. Further, according to the invention of claim 6, since the seal portion in contact with the front door is also hollow, there is an advantage that the entire vertical frame can have a strong structure.
