Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cabinet rack for accommodating various communication devices and control devices.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a cabinet rack 21 has at least four columns 22, 22, 22, 2 and
2, the upper side plate 23 and the lower side plate 24 are formed in a substantially rectangular parallelepiped. The shelf plate 25 has a flat plate portion 26 and side portions 27 and 27 formed by bending both left and right edges of the flat plate portion 26 at substantially right angles. ,
A mounting portion 28 is formed by bending a front edge portion of the side surface portion 27 outward at a substantially right angle, and a screw 30 is inserted into a screw insertion hole 29 formed in a plurality of locations of the mounting portion 28. It was screwed and fixed between the two columns 22 on the front side.

[0003] Further, as shown in FIG.
L-shaped rails 32, 32 each having an L-shaped cross section are brought into contact with each other in the front-rear direction of 2, 22, 22, 22, and are screwed and fixed, respectively. Mold rail 32,
32.

[0004]

However, in the above-mentioned conventional cabinet rack shelves, since only two screws on the front side are screwed and fixed by screws, if a heavy object is loaded on the rear part of the shelf plate. There was a drawback that the rear part of the shelf board was lowered.

[0005] The base plate is suitable for loading heavy objects,
When an electric device wired on the base plate is placed, it is difficult to attach and detach the base plate, and there is a disadvantage that the number of parts is large.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the conventional cabinet rack, an object of the present invention is to provide a shelf on which a shelf plate can be easily attached and detached from the front of the cabinet rack and a heavy object can be loaded. Provided is a cabinet rack having a plate, the structure of which is formed in a substantially rectangular parallelepiped by at least four pillars, an upper side plate, and a lower side plate, and a shelf rack attached with a shelf plate between the pillars. A flat plate portion, a side surface portion formed by bending both right and left edges of the flat plate portion at substantially right angles, and an attachment portion formed by bending a front edge portion of the side surface portion outward at substantially right angles. A notch is provided at the rear end of the side surface, and the shelf board is attached to the column by attaching means via the notch and the attaching portion.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A cabinet rack is formed in a substantially rectangular parallelepiped by four columns, an upper side plate and a lower side plate.
A shelf is provided between the columns. The shelf board is formed by bending a flat plate portion, a right and left edge of the flat plate portion at substantially right angles, and a front edge of the side portion is bent outward at a substantially right angle. And a substantially L-shaped notch at the rear end of the side surface. To attach the shelf board, insert the notch of the shelf board into the locking pin provided on the rear support column and lock it, and insert the screw into the screw insertion hole drilled in the mounting part on the front of the shelf board Then, it is screwed and fixed to the front column.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cabinet rack according to the present invention will be described with reference to the accompanying drawings of FIGS.

The cabinet rack 1 has four columns 2,
2, 2, 2, the upper side plate 3 and the lower side plate 4 are formed in a substantially rectangular parallelepiped, and a shelf 5 is provided between the columns 2, 2, 2, 2.

The shelf plate 5 has a flat plate portion 6, side portions 7, 7 formed by bending both left and right edges of the flat plate portion 6 at substantially right angles, and a front edge portion of the side portion 7 outwardly. A substantially L-shaped notch 9 is provided at the rear end of the side surface 7.

The shelf board 5 is mounted by inserting the notch 9 of the shelf board 5 into a locking pin 10 such as a pin or a screw, which is provided to face the inner side of the rear column 2 or 2.
The front surface of the shelf plate 5 is screwed into the screw insertion holes 11 formed at a plurality of locations of the mounting portion 8.
2 and is screwed and fixed to the columns 2 on the front side.

To remove the shelf 5, the screws 12 of the mounting portion 8 are removed, and then the rear of the shelf 5 is lifted slightly and pulled out to the front side to release the engagement of the notch 9. Even if the electric equipment is placed on the upper part, it can be easily removed.

In the present invention, the shape of the notch 9 is substantially L-shaped, but any shape can be used as long as the shelf 5 can be locked, and the shape can be appropriately changed without departing from the spirit of the present invention. is there.

[0014]

As described above, the cabinet rack according to the present invention is a cabinet rack which is formed in a substantially rectangular parallelepiped by at least four pillars, an upper side plate and a lower side plate, and has a shelf board attached between the pillars. The board is a flat part,
A side surface portion formed by bending both left and right edges of the flat plate portion at a substantially right angle, and a mounting portion formed by bending a front edge portion of the side surface portion outward at a substantially right angle, A notch is provided at the rear end of the side surface, and the shelf is attached to the support column by the attachment means via the notch and the attaching portion, so that the shelf can be easily attached and detached from the front of the cabinet rack. Since the plate is fixed to the four columns, it has an excellent effect that a heavy object can be loaded.
