Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a rack for storing electronic equipment. Specifically, the present invention relates to a rack for storing electronic equipment. Specifically, the end of a guide rail is supported by a frame to form a frame body, and a subrack is attached to this frame body. This invention relates to a rack for storing electronic equipment that supports the electronic equipment.

[Technical background of the invention] FIG. 1 shows a conventional rack for storing electronic equipment of this type. This rack consists of two frames 1, 1 whose upper ends are fixed to the ceiling or wall of a building and whose lower ends are fixed to the floor, and four upper and lower frames whose ends are supported inside the side plates 1a, 1a of the frames. It is composed of a set of guide rails 2, 2, 3, 3, and a subrack 5 supported by a frame 4 formed by the guide rails. The frame 1 cantilever-supports the guide rails 2 and 3 by fastening one end of the guide rails 2 and 3 with a screw 6. A sub-rack 5 is placed on the lower guide rail 3, and the upper part of the sub-rack is placed on the lower guide rail 3. It is fastened to the upper guide rail 2 with screws 7 to hold the subrack 5. This sub-rack 5 has a housing formed by side plates 5a, 5a and several shelves 5b extending between the side plates, and an electronic device 8 is housed between each shelf.

[Problems with background technology]

By the way, such an electronic device storage rack uses guide rails 2 and 3 with sufficient strength in order to support the heavy electronic device 8, and the thickness W of the guide rails 2 and 2 is frame 1
Since the screw 6 is several times thicker than the thickness W', the female thread part of the screw 6 is formed on the guide rail 2, 3 side, and the screw 6 is
are screwed onto guide rails 2 and 3 from the outside of the frame 1. Therefore, in the case of expansion of a modified area where many racks are installed adjacent to each other, such as a multiplex communication control device, the screws 6 mentioned above cannot be installed and removed, making it difficult to install and remove the guide rails 2 and 3. It was difficult to change the position of the guide rail. Further, such an electronic device storage rack uses the frame 1 made of angle material in order to support the heavy electronic device 8 and the guide rails 2 and 3 as described above. Therefore, the width of the frame 1 is limited, and as shown in FIG. 1, it is not possible to maintain sufficient pitch between the screws 6, and it is also difficult to ensure the strength of the screws 6. Furthermore, it is also difficult to ensure the strength of the frame 4 that supports the electronic device 8 via the subrack 5.

[Purpose of invention]

In view of these problems, the purpose of this invention is to
To provide a rack for storing electronic equipment in which guide rails can be easily installed and removed and which can ensure sufficient strength.

[Summary of the idea]

In order to achieve this objective, the present invention forms the frame and the guide rail into a U-shape by sheet metal processing, and forms an engagement receiving part and an engagement tongue by cutting and bending them. The guide rail is supported by the frame by fitting the engagement receiving portion and the engagement tongue into each other from the inside of the frame.

[Example of idea]

The present invention will be described below with reference to embodiments shown in the drawings. FIG. 2 shows a rack for storing electronic devices according to the present invention. A pair of upper and lower guide rails 1 formed in a U-shape.
2, 13, and the frame 14 formed by them
It consists of a subrack 15 that is housed inside.

A plurality of engagement receiving portions 16 are formed in the frame 11 along the ends of side plates 11a, 11a corresponding to both sides of the U-shape, and a back plate 16 corresponding to the engagement receiving portions is formed on the frame 11.
A female threaded portion 17 is formed in 1b. As shown in FIG. 3, this engagement receiving part 16 is formed by cutting and bending inward so that the front part is open by press working, and a cutout part 16a is formed at the front opening edge. It is. On the other hand, the guide rail 13 has an engaging tongue piece 18 formed near the upper edge of one end of the side plate 13a corresponding to both sides of the U-shape, and a bottom plate 18 corresponding to the center of the U-shape and the side plates 13a.
An L-shaped back plate 13c is attached to the end of the portion where the parts b meet, and a screw insertion hole 19 is bored therein.
As shown in FIG. 3, the engaging tongue piece 18 is formed by cutting and bending outward so that the upper and lower sides and the rear are open by press working, and forming a tongue piece that faces rearward. be. In addition, upper guide rail 1
Each element of the guide rail 2 is formed similarly to the guide rail 13 described above.

As shown in FIG.
into the notch 16a of the engagement receiving part 16 of the frame 11, and insert the screw 20 into the hole 19 of the guide rail 13.
The guide rail 13 is screwed into the female threaded portion 17 of the frame 11 via the guide rail 13, and the guide rail 13 is supported between the side plates 11a, 11a of the frame 11, as shown in FIG. Similarly, the upper guide rail 12 is also supported between the side plates 11a, 11a of the frame 11. The sub-rack 15 is housed between the upper and lower guide rails 12 and 13 of the frame body 14 formed in this way,
The front side plates 15a, 15a of the sub-rack are attached to the front side tongue pieces 12b, 13 of the guide rails 12, 13.
d with screws 21 (see Fig. 2).
In addition, subrack 15 adopted in this example
There is almost no difference from the conventional subrack 5 mentioned above.

FIG. 5 shows another engagement structure between the frame 11 and the guide rail 13. In this embodiment, the above-described frame 11 and guide rail 1 are
Apart from the engagement receiving portion 16 and the engagement tongue piece 18 of No. 3,
Side plate 13 of frame 11 and guide rail 13
An engagement receiving portion 22 and an engagement tongue piece 23 are formed at the extreme ends of a and 11a. The engagement receiving part 22 formed on the frame 11 is cut and bent inward using a press in the same manner as the engagement receiving part 16, and an opening is formed in the upper part, and a notch is formed at the edge of the opening. 22a, and a screw insertion hole 24 is further bored in the protruding surface. On the other hand, the engaging tongue piece 23 formed on the guide rail 13 is cut and bent outward by a press in the same manner as the engaging tongue piece 18, so that the tongue piece protrudes downward. A female threaded portion 25 is formed on one piece. Incidentally, the upper guide rail 12 also has various elements formed in the same manner as the guide rail 13 described above.

The guide rail 13 formed in this manner has its engaging tongue piece 18 fitted into the notch 16a of the engaging receiving part 16 of the frame 11, and at the same time, the engaging tongue piece 23 is fitted into the notch part 16a of the engaging receiving part 22 of the frame 11. It is fitted into the notch 22a from above, and the screw 26 is screwed into the female threaded part 25 of the engaging tongue piece 23 through the hole 24, so that it is supported by the frame 11. Note that the upper guide rail 12 is also assembled to the frame 11 in the same manner.

Note that the frame 11 shown in FIGS. 2 to 4 has a recess 11c formed in its back plate 11b to increase the strength of the frame 11, but such deformation may cause the guide rails 12, 13 to Various embodiments can be adopted within the scope of the utility model registration claim.

[Effect of idea]

As mentioned above, in the electronic device storage rack according to the present invention, the guide rail can be attached to and detached from the frame from the inside of the frame, so even when the racks are installed adjacent to each other, the position of the guide rail can be changed. etc. can be easily performed. Moreover, the guide rail and the frame are each formed into a U-shape by sheet metal processing, and the frame is constructed by joining them together, which improves the strength of the frame and improves the electronic Can sufficiently withstand the weight of the equipment.
