DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rack-mounting bracket for supporting a shelf board mounted on a cabinet rack, and more particularly to a rack-mounting bracket which can be easily mounted and can be additionally mounted after a system is upgraded.

[0002]

2. Description of the Related Art Conventionally, as a method of mounting a shelf board having various electronic components and a printed wiring board therein on a cabinet rack, generally, a rack mount bracket is attached to the cabinet rack, and the shelf board is mounted by the rack mount bracket. A method of support is employed. The shelf board mounted on the cabinet rack is used by being connected to various electronic devices by wiring such as connectors from the back.

With reference to FIG. 7, a description will be given of a conventional general rack mount fitting for mounting a shelf board. As shown in FIG. 1, the conventional rack mount fitting is a fitting attached to a cabinet rack 1 formed in a rectangular parallelepiped shape by four pillars, and is installed so as to oppose in a depth direction on both side surfaces of the cabinet rack 1. A pair of beams (beams) 50, a pair of angles (arms) 51 that intersect with the pair of beams 50 and are fixed in the height direction of the cabinet rack 1, and are fixed to the pair of angles 51. And a pair of L-shaped support fittings 52 disposed opposite to each other in the depth direction of the side surface of the cabinet rack 1.

The pair of beams 50, the angle 51 and the L-shaped support bracket 52 are firmly fixed by screws or the like. Then, while the shelf board 2 is mounted on the L-shaped support bracket 52 thus attached,
The shelf plate 2 was mounted on the cabinet rack 1 by fixing the front plate 2a of the shelf plate 2 to the front surface of the cabinet rack 1 by screws or the like.

[0005]

However, in such a conventional rack mount fitting, the L-shaped support fitting 52 on which the shelf plate 2 is mounted is fixed by two kinds of fittings, the angle 51 and the beam 50. These beams 5
0, cabinet rack 1 for mounting angle 51
It is necessary to design each of them individually according to the size such as depth width and height. Further, in general, the cabinet rack 1 has two kinds of standards of an inch pitch and a milli-pitch depending on the interval between screw holes. Therefore, it is necessary to design the beam 50 according to each standard, and the manufacturing process of the metal fitting is required. There is a problem that it becomes complicated and lacks versatility.

In addition, since it is constituted by three different kinds of metal fittings, ie, the beam 50, the angle 51, and the L-shaped support metal fitting 52, the structure of the metal fittings becomes complicated and the mounting work is complicated. Further, since the angle 51 and the L-shaped support bracket 52 are attached to the side surface of the cabinet rack 1 by screws or the like via the beam 50, when additional mounting is performed after system up, the shelf board 2 already mounted is required. In addition, there is a problem that all the metal fittings must be removed.

Although the use is different from that of mounting a shelf board, there is a rack mounting apparatus described in Japanese Utility Model Laid-Open No. 1-160875 as a technique for mounting and storing electronic equipment such as a mixing amplifier in a cabinet rack. However, in the device described in this publication, the size, shape, and the like of the equipment and devices to be stored are designed in accordance with the depth, width, and height of the cabinet rack determined in advance. In addition, there is no technical idea that takes into account additional mounting or the like after the system is up, and the above-described problems of the conventional technology cannot be solved.

The present invention has been proposed in order to solve such problems of the prior art, and can be adapted to any cabinet rack size with only a simple structure, and the mounting work is extremely easy. It is another object of the present invention to provide a rack mount fitting which can easily be additionally attached to a cabinet rack after system upgrade.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, a rack mounting bracket according to the present invention is a bracket for supporting a shelf board mounted on a cabinet rack, and includes a vertical section L having an upright portion and a flat portion. It is formed of a U-shaped plate-like member, and has an attachment surface fixed to the back of the cabinet rack at one end, and is disposed on both side surfaces of the cabinet rack with the flat portions facing each other. A pair of metal fitting bodies for mounting a shelf, a stepped boss attached to both side surfaces of the shelf, and a long hole-shaped provided in an upright portion of the metal fitting body engaged with the stepped boss. Preferably, the slide hole has a portion having a diameter larger than the step of the stepped boss and a portion having a smaller diameter than the step of the stepped boss. Mounting groove that is long in the width direction Provided was located as a constituent, it is constituted with a plurality of the mounting groove as required in the height direction of the cabinet rack.

[0010]

According to the rack mount fitting of the present invention having the above-described structure, the fitting for supporting the shelf board is only the L-shaped fitting main body, so that the structure of the fitting is simplified and the mounting work can be performed very easily. Further, since the fitting body moves in the depth and width directions by the slide holes and the mounting grooves formed in the fitting body, it is possible to cope with cabinet racks and shelves having different depths and / or widths. It can be easily installed.
