2. Description of the Related Art Generally, in mobile communication exchanges and the like,
A rack is used to store a large number of panels formed by a printed circuit board. As such a rack, a rack as shown in FIG. 14 has been used. FIG. 14 is a schematic perspective view showing a conventional rack, and shows a case where two racks are used in a vertically stacked state.

The conventional rack shown in FIG. 1 has a rack body 101 (101a) having a storage space for accommodating a plurality of panels 120 (120a) therein, and an opening of the rack body 101 communicating with the storage space can be opened and closed. Cover 102
(102a) is rotatably mounted.

Here, in such a conventional rack, as shown in FIG. 14, usually, the cover 102 (102a) can be opened downward at an angle of substantially 180 degrees with respect to the rack body 101 (101a). Installed. The rack having such a configuration is used in a state where the rack is stacked in two stages, and the cover 102 (102a)
By appropriately opening and closing the panel, it is possible to take out and put in the internal panel, and perform necessary operations and operations.

However, in such a conventional rack,
When the cover is opened, the cover expands almost 180 degrees toward the lower side (see FIG. 14). Therefore, when the racks are stacked in two stages, opening the cover of the upper rack causes the front of the lower rack to open. The side will be covered.

That is, while the cover of the upper rack is being opened and operated, the cover of the lower rack cannot be opened, and even if the cover of the lower rack has been opened in advance, the upper cover is opened. If this happens, the opening of the lower rack will be covered, and in the end, it has been impossible to open and operate the covers of the upper and lower racks simultaneously. For this reason, when using a rack with two upper and lower tiers, one of the covers must be closed,
There is a problem that opening and closing the cover is extremely complicated, and efficient work cannot be performed.

Therefore, in order to solve such a problem that occurs when the conventional rack is used in two vertical stacks, a rack having a cover opening / closing angle fixing structure as shown in FIGS. 15 and 16 has been proposed. Have been. FIG. 15 is a schematic perspective view showing a main part of a conventional rack provided with the cover opening / closing angle fixing structure. FIG. 16 is a schematic main part explanatory view showing the cover opening / closing angle fixing structure of the rack. () Is an explanatory view from the side, and (b) is an explanatory view from the front.

In the rack having the conventional cover opening / closing angle fixing structure shown in these figures, a cover fixing method is employed in which a cover 202 for covering a front opening of a rack body 201 accommodating a plurality of panels 220 is fixed in a state where the cover 202 is opened. Means 210 are provided. The cover fixing means 210 includes two stays 2.
11 and 212 are configured to be foldable via a rotating part 215. And these two stays 211, 21
2 have a rack body 210 and a cover 202, respectively.
It is rotatably attached to the rotating parts 213 and 214 fixed to the side.

In the conventional rack having the cover opening / closing angle fixing structure having such a configuration, when the cover 202 is closed on the rack body 201 side, the two stays 211 and 212 are in a folded state. (See FIG. 16A). On the other hand, when the cover 202 is opened,
As a result, the stays 211 and 212 are expanded, and FIG.
As shown in FIG. 5, the two stays 211,
Reference numeral 212 denotes a single rod, which is installed between the cover 202 and the rack body 201, and the cover 202 is fixed in an expanded state. When closing the cover 202, the cover 202 can be closed to the rack body 201 side by folding the stays 211 and 212 again via the rotating part 215.

As described above, in the conventional rack having the cover fixing structure, the cover 202 can be fixed while being opened at an angle of about 90 degrees with respect to the rack body 201, and can be vertically arranged in two stages. Even when racks are stacked, both the upper and lower racks can keep the cover 202 open, so that the racks used in the upper and lower stages, which have been a problem in the past, can be simultaneously deployed and operated simultaneously. Was.

[0011]

However, in the conventional rack having such a cover opening / closing angle fixing structure, the unfolding angle at which the cover is fixed is substantially 90 degrees with respect to the rack body, and the angle beyond that angle is larger than 90 degrees. Could not be fixed in the open state. For this reason, when the cover is opened, the cover projects substantially horizontally to the front of the rack, which causes a new problem of hindering the operation.

The conventional cover opening / closing angle fixing structure is
Because the ends of the two stays were connected in an overlapped state, and the two stays had to be foldable, and the rack side and the cover side had to be rotatable, respectively. In addition, there is a problem that both the size in the depth direction (x shown in FIGS. 15 and 16) and the size in the width direction (y shown in FIGS. 15 and 16) of the fixing means increase. Such a large fixed structure,
This is a serious problem particularly in racks of mobile communication exchanges and the like that require high-density mounting because there is almost no empty space in the storage space, and it is actually difficult to employ such a large cover fixing means. Was.

Further, in this cover opening / closing angle fixing structure, the rotating portion for attaching the stay is fixed to the rack body side and the cover side by screwing. It is exposed on the outer surface of the rack, and in particular, the screw head on the cover side is exposed on the cover surface on the front side of the rack, which impairs the appearance of the cover and the entire rack and lowers the commercial value of the entire device. There was also the problem of letting them do it.

The present invention has been proposed in order to solve such problems of the prior art, and the cover is extended upward by 90 degrees or more toward the upper part of the rack body only by a simple and small structure. By making it possible to fix the unfolded cover at a desired angle, work and operability with respect to the rack body can be improved, the cover fixing structure can be downsized, and the appearance of the rack is impaired. In particular, an object of the present invention is to provide a rack with a cover opening / closing angle fixing structure suitable for a rack used in a two-stage stack in the vertical direction.
