[Industrial application field]

The present invention relates to a novel structure of a shelf for accommodating electronic equipment, and in particular to a structure of a shelf that can accommodate small devices such as power supplies in a drawable manner.

For this purpose, it is equipped with a shelf board with guide rails.

[Problem to be solved by the invention]

When storing power supplies other than printed circuit boards on this shelf, the devices are fixed directly to the shelf with screws, so these devices cannot be removed from the shelf for maintenance or inspection. This is troublesome and requires a solution.

SUMMARY OF THE INVENTION In view of the problems of the prior art, it is an object of the present invention to provide a structure in which a small device such as a power supply device can be freely drawn out and stored in a shelf with a simple configuration.

[Prior Art] Electronic equipment is generally installed in a single rack with multiple shelves housing a large number of printed circuit boards in parallel and a shelf housing power supplies, etc. be.

In consideration of manufacturing convenience, all shelves are made to have the same shape as shown in Figure 5, and are designed to accommodate printed circuit boards in a removable manner. In each of the left and right areas at the bottom of
By fixing a first rail extending in the depth direction, fixing a second rail corresponding to each of the first rails on the shelf slope of the shelf, and sliding the first rail on the second rail, In the structure in which the small device is mounted in such a way that it can be taken in and taken out through the front opening of the shelf, the first and second rails are formed of a section having a U-shaped or Z-shaped cross section, and a section extending in the longitudinal direction of the section is provided. The two walls are fixed in a position where they are in contact with the bottom of the device and the shelf of the shelf, and the front end of one wall of each profile is bent at right angles so that the small device is placed in an upright position that contacts each other when the device is housed in the shelf. A structure for mounting a small device in a shelf, characterized in that a front wall is formed, screw holes are provided at mutually corresponding positions in each front wall, and both are fixed with screws through the screw holes. achieved by

Hereinafter, the present invention will be explained in more detail based on preferred embodiments shown in the drawings.

〔Example〕

FIG. 1 shows a perspective view of a mounting structure according to a first embodiment of the present invention.

On both left and right areas of the bottom of the power supply device 2 housed in the shelf 1, there are three walls 3a, 3b. A first rail 3 made of a section 3c having a U-shaped cross section is fixed along the depth direction by screws or welding. The first rail 3 is attached so that the open surfaces of the U-shaped cross sections face each other and face inward. The front end of the vertical wall 3a extending in the longitudinal direction is bent at a right angle to form a front wall 3d that closes the front surface of the U-shaped cross section.
is formed. A pair of upper and lower holes 6 are provided in this front wall 3d.

On the other hand, on the shelf board 5 of the shelf, there are three walls 4a, 4b at right angles to each other at positions corresponding to the first rail 3.
, 4c, which is made of a section having a U-shaped cross section.
The rail 4 is fixed along the depth direction by screwing or welding.

The second rail 4 is installed with its horizontal wall 4b in contact with the shelf board 5 of the shelf so that the open surface of the U-shaped cross section faces upward. Both front and rear ends of the vertical wall 4C located inside the second rail 4 are bent at right angles to close the front and rear surfaces of the U-shaped cross section, forming front and rear walls 4d and 4e. A tapped hole 7 for screw fixing is provided in the. A gap X is provided between the bent free end of the front and rear walls 4d and the other vertical wall 4a facing it, through which the vertical wall 3a of the first rail 3 can pass. A gap y is provided between the lower edge and the horizontal wall 4b through which the horizontal wall 3b of the first rail 3 can pass.
(see figure).

The height H of the first rail 3 is set larger than the height h of the second rail 4.

Further, the distance between the gaps X formed in the pair of left and right second rails 4 is equal to the distance between the vertical walls 3a of the pair of left and right first rails 3.
is set equal to the distance between them.

When housing the power supply device 2 in the shelf 1 configured in this way, first the first rail 3 fixed to the power supply device 2 is
The rear end of the vertical wall 3a of the second rail 4 is positioned so as to coincide with the front end of the gap X between the front wall 4d of the second rail 4 fixed to the shelf l and the vertical wall 4a. When the power supply device 2 is gradually pushed into the shelf 2, the first rail 3 is correctly guided with its vertical wall 3a aligned with the vertical wall 4a of the second rail 4, as shown in FIG. It can fit into shelf 1 without getting twisted. And the front wall 3d of the first rail 3
is in contact with the front wall 4d of the second rail 4, and the rear end of the horizontal wall 3C is accommodated in a predetermined position with the rear end slightly passing through the gap y between the rear wall 4e and the horizontal wall 4C. Since the lower hole 6 provided in the front wall 3d is provided at the same height as the tap hole 7 in the front wall 4d, the two coincide in this state.

Then, a screw 8 is screwed into the tapped hole 7 through the hole 6 to fix both rails 3 and 4 together.

As a result, the power supply device 2 controls the front walls 3d and 4d.
Also, the left and right movement can be controlled by screwing both rails 3 and 4.
Due to the contact between the vertical walls 3a and 4a of the second rail, the upward movement is further restricted by the front and rear walls 4d and 4e of the second rail,
Stably held within the shelf l.

When taking out the power supply device 2 from the shelf 1 for maintenance, inspection, etc., loosen and remove the screws 8 exposed on the front, and then remove the device 2 along the second rail 4 in the opposite direction to the above operation. Just pull it out.

In addition, the height H of the first rail 3 is set high, and each front wall 3d
The reason why the two upper and lower holes 6 are provided is to enable the left and right rails to be manufactured as members of the same shape. 2nd rail 4
The upright walls 4d and 4e are provided at the front and rear ends for the same reason.

FIG. 3 shows a second embodiment of the invention. According to this, the second rail 14 provided on the shelf side is connected to three mutually orthogonal walls 14a. It is composed of a shape material consisting of 14b and 14c, and front and rear walls 14d and 14e are provided at both ends,
Its operation and effects are substantially the same as those of the first embodiment described above. In this example, the top surface of the horizontal wall 14b that is in contact with the shelf board 5 of the shelf is completely open, and a screw is inserted into the tap hole 11 provided in the shelf board 5 through the hole 10 provided therein. This has the advantage that the work of fixing the rail 14 by screwing the rails 12 together can be easily performed.

The third embodiment shown in FIG. 4 is an improvement on this, and instead of the tap hole 11, a slit 20 extending in the horizontal direction is provided at a corresponding position on the shelf board 5. Second rail 14
When installing the shelf board 5, a screw 12 is inserted through the hole 10 provided in the shelf board 5, and the screw 12 is screwed into the tap hole 11° provided in the presser plate 21 placed on the lower side of the shelf board 5, thereby fixing the shelf board 5. .

According to this, since the mounting interval between the left and right second rails 14 can be freely changed within the range of the length of the slit 20, it is possible to easily accommodate cases where the widths of the small devices to be accommodated are different. It is.

〔Effect of the invention〕

As described in detail above, according to the present invention, small devices can be reliably accommodated within the shelf by combining only two types of rails, and devices can be easily installed by simply removing the screws exposed on the front. Since it can be pulled out, it is possible to significantly improve workability and safety compared to conventional structures.
