Description

[Detailed Description of the Invention] The present invention relates to an improvement of a rack structure for storing shelves such as electronic equipment.

Multiple shelves, etc. that house structural circuits such as electronic equipment and communication equipment are constructed by securing upright pillars facing each other on the left and right with upper and lower frames, covering three sides with side plates and a rear plate, and placing a front panel on the front side. In this case, shields or the like are screwed into mounting holes arranged in the vertical direction of the pillars, and the front side of the shields is covered with a front door.

These structures are usually called a frame, a locker, a structure, etc., but in the present invention, they are collectively called a frame.

Conventionally, each function of electronic equipment and one system was completed on a rack-by-rack basis.

Therefore, when maintaining and inspecting these devices, all of the shelves in the rack are to be inspected at the same time, so it is preferable that the front door has a single-panel structure or two double-panel doors so that the whole can be seen.

However, in recent years, as circuit elements have become smaller and packaging technology has progressed, a plurality of functions or systems have come to be installed in one rack.

Therefore, if a front door with a conventional structure is provided, unnecessary shields, etc. will be exposed during maintenance and inspection of the equipment, which may lead to misidentification or erroneous operation by workers. Or a front cover is now required.

In order to meet this requirement, it is necessary to attach the above-mentioned front door or front cover to the conventional frame structure, that is, to attach the front door or front cover directly using the shield mounting holes provided on the pillars, or to attach the front door or front cover directly to the shelf itself. A method of mounting it on the front is also considered, but the former method is to fit it within the height dimension of a shelf with a height equivalent to 1 pitch or 2 pitches of mounting holes such as a shelf on a pillar, and attach it to the front door or It is difficult to attach the front cover, and the latter method is not preferred because it requires special mounting hardware for the blank plate covering the space for the spare shelf.

The purpose of the present invention is to eliminate the above-mentioned inconvenience, and the purpose is to arrange a pair of side posts with C-shaped cross-section openings facing each other along the left and right supports of the frame. A piece provided with at least one threaded portion is inserted into the C-shaped cross section so as to be slidable up and down, and a mounting bracket for attaching a surface cover such as a shield is screwed to the threaded portion of the piece. This is accomplished by providing storage racks with special features.

The present invention will be explained below using the drawings.

Fig. 1 is a schematic explanatory diagram of the overall structure of a storage rack according to an embodiment of the present invention, Fig. 2 is a diagram of the surface cover mounting structure of Fig. 1, and Fig. 3 is a perspective view of the main structure or parts of Fig. 2. shows.

In Fig. 1, a pair of front columns 1 and a pair of rear columns 1' stand upright, and their upper ends are engaged with an upper frame 2, and their lower ends are engaged with a lower frame 3 to form a frame. Side plates 4 are screwed onto the left and right side surfaces of the frame, and the rear surface is covered with a rear plate 5.

The column 1 with a U-shaped cross section has multiple mounting holes 6 for shields etc. on the front side.
The left and right ends of the shield 7 are screwed into the mounting holes 6, and a pair of side pillars 8 with substantially C-shaped cross-section openings facing each other are attached to the outer surfaces of the pillars 1 that stand upright on the left and right sides. A surface cover 10 of the shelf 7 is screwed onto the side post 8 via a mounting bracket 9 or the like with a screw 11.

Note that in this case, the fastener is not limited to a zipper, but may be a one-touch fastener or the like.

In Figures 2 and 3, screws 13 are attached to the outer surface of the column 1.
The almost O-shaped metal fitting 12 screwed in at a has 8 side pillars and 1
3b, and a female threaded piece 14 is inserted into the substantially C-shaped cross section of the side post 8 so as to be vertically slidable.
The C-shaped cross-sectional opening portion of the side post 8 is sandwiched between the mounting bracket 9 and the mounting bracket 9, and is fastened with a screw 15.

The mounting bracket 9, which is formed by integrating triangular reinforcing members on both sides of the L-shaped bracket, has a female thread 18 on a surface perpendicular to the surface fastened to the side post 8. cover 10
is screwed in with a screw 11 via a screw seat 16.

In addition, 4 in FIG. 2 is a part of the side plate of the storage rack, and 7a shows a part of the structural member of the shelf 7 screwed onto the support column 1.

FIG. 4 is a vertical sectional view of the mounting bracket 9 and the piece 14 in FIGS. 2 and 3, and FIGS.
Another embodiment is shown in the same sectional view as in FIG.

In the figure, 8 is a part of the side pillar, 9, 9a are mounting brackets, 14, 1
4 a and 14 b are pieces, 15 is a screw, 17 is a tapped hole drilled in the piece 14 or piece 14b, 18 is a tapped hole drilled in the mounting bracket 9 or mounting bracket 9a, and 19 is a screw fixed to the piece 14a. 20 indicates a nut.

FIG. 4 shows the standard structure of the present invention, with a mounting bracket 9 having one tapped hole 18 (corresponding holder for fasteners, etc.) on the front surface, a piece 14 having one tapped hole 17, and a surface (not shown). One end of the cover 10 (FIG. 2) has a one-to-one correspondence with each other.

In FIG. 5, a screw 19 is fixed to the piece 14a, and a nut 20 that is screwed onto the male screw 19 is fastened by clamping the cross-sectional opening of the side post 8 and the mounting bracket 9.

The feature of this structure is that the piece 14 protrudes from the opening of the side post 8.
It is easy to move it to a desired position by holding the tip of the male screw 19 of (a).

The piece 14b in FIG. 6 has two tapped holes 17 formed at appropriate intervals, and the screw holes 17 correspond to different mounting fittings 9, and are fastened with screws 15, respectively.

One ends of two surface covers (not shown) are screwed onto the two mounting fittings 9.

That is, there is an advantage that once the position of one front cover is set, the position of the adjacent front cover can be set accurately without any adjustment.

FIG. 7 is another structure having the same characteristics as FIG. 6,
A long mounting bracket 9a having two tapped holes 18 at appropriate intervals is fastened to a piece 14 having one tapped hole 17 using l screws 15.

As explained above, the rack for storing shelves, etc. according to the present invention has practical features that make it easy to attach a surface cover or a front door that is adapted to the shelves, etc. attached to the rack, the functional units inside the rack, or the system units inside the rack. The effect is significant.
