Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cabinet provided with a frame.

[0002]

2. Description of the Related Art Conventionally, in a cabinet in which a frame is assembled in a rectangular parallelepiped, electric devices and small items are stored and attached.
In this cabinet, objects are often loaded and unloaded from the front and back of the rectangular frame, so the front and back are not attached or have doors attached.
Therefore, a reinforcing frame cannot be attached to the front and rear surface portions.

[0003]

However, since the conventional general-purpose cabinets described above do not have reinforcing frames attached to the front and rear surfaces thereof, they are erected at the four corners as shown in FIG. 9 in the event of an earthquake. As shown in Fig. 10, a force is directly applied to the connecting point (marked with ○) between the vertical frame and the front and rear horizontal frames, and it tilts in the left-right direction. To prevent this, use the alternate long and short dash line in Fig. 9. It was necessary to add braces to the rear face. This brace must have a dedicated length for each different size of the cabinet, the workability of assembly is poor, and it also interferes with the putting in and out of the rear part. there were.

BEST MODE FOR CARRYING OUT THE INVENTION Next, preferred embodiments of the present invention will be described. The frame body 1 has a rectangular parallelepiped shape, and the frame body 1 includes a front vertical frame 11 on the left side and an upper and lower end portion of the front vertical frame 12 on the right side, and an upper horizontal frame 21 on the front side.
And the upper and lower ends of the left rear vertical frame 13 and the right rear vertical frame 14 are connected to both ends of the front lower horizontal frame 22 and both ends of the rear upper horizontal frame 23 and the rear lower horizontal frame 24. The left front vertical frame 11 and the left rear vertical frame 13 are connected at the upper and lower ends thereof to the upper horizontal depth frame 31 and the lower horizontal depth frame 32 at both ends thereof, and are connected to the right front vertical frame 12 at the same time. The upper and lower ends of the right rear vertical frame 14 are formed by connecting both ends of an upper horizontal depth frame 31 and a lower horizontal depth frame 32.

40 is arranged on the left and right inside of the frame main body 1, that is, in the middle of the front vertical frames 11 and 12 and the rear vertical frames 13 and 14, the upper horizontal depth frame 3 is provided.
1 is an internal vertical frame in which upper and lower end portions are connected to a lower horizontal entertainment frame 32. The inner vertical frame 40 is connected to a depth reinforcing frame 50 mounted between the front vertical frames 11 and 12 and the rear vertical frames 13 and 14. It should be noted that, as shown in the figure, the inner vertical frame 40 is attached to the depth reinforcing frame 50 by mounting arm fittings 51.
, But the one arranged so as to contact the depth reinforcing frame 50 may be directly connected.

Also shown is an internal vertical frame 40.
Front vertical frames 11, 12 and rear vertical frames 13, 1
2 are arranged in the middle of 4, and the two internal vertical frames 4
0 and front vertical frame 11, 12 and rear vertical frame 13,
14 are connected to each other by a wide upper horizontal depth frame 31, a lower horizontal depth frame 32, and a depth reinforcing frame 40 to form a planar trapezoidal frame structure on the left and right sides.

Reference numeral 60 denotes a mounting base for connecting the lower end portion of the internal vertical frame 40 to the lower horizontal depth frame 32. The mounting base 60 has a wide lower end surface of a square tube-shaped base body 61. Nuts 62 formed on the front surface of the base body 61 while contacting the upper surface of the lower horizontal depth frame 32
The bent piece 62 with a is attached to the inner upper piece 32a bent green to the inner side of the lower horizontal depth frame 32 by a bolt, and the collar plate piece 63 with a nut part bent on the outer side of the rear surface of the base body 61. , 63 to the lower horizontal depth frame 3
The lower end of the inner vertical frame 40 is attached to a mounting piece 64 with a nut portion 64a that is attached to the outer upper piece 32b bent at the outer edge of the second piece by bolts and is erected on the upper surface of the base body 61 by means such as welding. While installing with bolts,
The lower end of the inner vertical frame 40 is connected to the lower horizontal depth frame 32 by bringing the end of the inner vertical frame 40 into contact with the upper surface of the base body 61.

It should be noted that the height of the inner vertical frame 40 shorter than the height of the cabinet can be used by interposing the mounting base, and the frame main body 1 can be easily mounted after assembly, but without the lower end of the inner vertical frame 40. The portion may be directly connected to the lower horizontal depth frame 32, and any connecting means may be used as long as it can be surely connected. The specific means for connecting the upper end of the inner vertical frame 40 to the upper horizontal depth frame 31 is similar to the means for connecting the lower end of the inner vertical frame 40 to the lower horizontal depth frame 32. In addition, each of the upper horizontal depth frame 31 and the lower horizontal depth frame 32 is connected to the internal vertical frame 40 by forming a wide plate shape, and the upper horizontal depth frame 31 and the lower horizontal depth frame 32 are connected to each other. The outer frame part and the inner vertical frame 40 may be divided into inner horizontal frame parts.

In the cabinet thus constructed, an internal vertical frame 40 having upper and lower end portions connected to the upper horizontal depth frame 31 and the lower horizontal depth frame 32 is arranged on the inside of the right and left sides of the rectangular parallelepiped frame body 1. At the same time, the inner vertical frame 40 is connected to the depth reinforcing frame 50 mounted between the front vertical frames 11 and 12 and the rear vertical frames 13 and 14, so that the left and right of the frame body 1 have a double frame structure. The wide upper bottom of the left and right double-layered frame structure (the ellipse shown in FIG. 8) is where the force acts on the integrated pillars and plates that are shaded in FIG. ), So it will not withstand tilting to the left and right. Therefore, since it is not necessary to make braces on the front and rear surfaces of the frame body 1, the front and rear surfaces can be opened and put in and taken out. In addition, the double-sided frame structure on the left and right acts on the integrated pillar and plate even with respect to the sway in the depth direction, so that it has good earthquake resistance. Therefore, as shown in FIG. 1, not only the side plate 2 is attached but also the side plate is not required, the braces on the left and right sides can be eliminated.

Further, two inner vertical frames 40 are arranged between the front vertical frames 11 and 12 and the rear vertical frames 13 and 14, and the two inner vertical frames 40, the front vertical frames 11 and 12 and the rear vertical frames 11 and 12 are arranged. The vertical frames 13 and 14 are connected to each other by a wide upper horizontal depth frame 31, a lower horizontal depth frame 32, and a depth reinforcing frame 40 to form a flat trapezoidal frame structure on the left and right sides. In this case, since the frame structure of the flat trapezoidal arrangement is a structure which is not deformed not only in the left-right direction but also in the front-back direction and the diagonal direction, it does not endure the left-right swing and tilt as described above. Needless to say, it does not distort forward, backward, or diagonally.

[0012]

As described above, in the cabinet of the present invention, the left and right sides of the frame body have a double frame structure. Therefore, even if the front and rear surfaces of the frame body 1 are not braced, an earthquake or the like will not occur. It resists shaking from side to side and does not tilt. Therefore, the front and rear surfaces can be opened and put in and out. Further, in the case where the double frame structure is formed on the frame structure of the trapezoidal plane arrangement, of course, as described above, it does not endure the right and left shaking, and it is distorted diagonally to the front and back and diagonally. There is no such thing. Therefore, the present invention is a great solution to the industry as it solves the problems of the cabinet having the conventional frame.
