The present invention relates to a box for storing electrical equipment, such as an equipment storage rack capable of storing electrical equipment.

Conventionally, equipment storage racks capable of storing electrical equipment and communication equipment, which are an example of electrical equipment storage boxes, are provided with cable passage holes for passing cables extending from the stored equipment to wire the equipment storage racks together. For example, the equipment storage rack described in Patent Document 1 has such cable passage holes in the side panels.

JP 2009-224630 A

In general, when storing various devices in an electrical device storage box, the devices are often stored with their cable connections facing forward or backward, taking into consideration ease of use after storage. Therefore, if the wire-passing hole is provided in the side panel as described in Patent Document 1, the cable must be passed through the gap between the device and the side panel when pulling out the cable from the wire-passing hole, which creates a problem of poor workability.

Therefore, the present invention has been made in consideration of the above problems, and aims to provide a box for storing electrical equipment that is easy to work with when threading cables.

In order to achieve the above object, the present invention provides a box for storing electrical equipment, the box having a rectangular bottom when viewed from above and a rectangular top when viewed from above, the four corners of which are connected to each other by pillar members extending in the vertical direction,
At least one of the pillar members is formed by bending a band-shaped metal plate extending in the up-down direction, and has a first bent portion bent outward in the left-right direction, a second bent portion bent outward in the front-rear direction continuing from the first bent portion, a third bent portion bent inward in the left-right direction continuing from the second bent portion, and a fourth bent portion bent inward in the front-rear direction continuing from the third bent portion, and a space surrounded by the first bent portion, the second bent portion, the third bent portion, and the fourth bent portion is used as a space for passing wires , and a wire passing hole communicating with the space is opened in at least one of the second bent portion and the third bent portion , and a slit extending in the up-down direction is formed near the wire passing hole. On the other hand, a slide cover having a plate-shaped cover body and an operating part formed by bending an end of the cover body is attached to the pillar member with the operating part protruding outward from the pillar member through the slit and abutting against the surface of the pillar member, and the slide cover is slidable in the vertical direction along the slit between a cover position in which the cover body blocks the wire passage hole and a retracted position in which the wire passage hole is opened, and further, a long hole that is long in the vertical direction is provided in the operating part, while a round hole that is exposed in the long hole when the slide cover is in the cover position and a round hole that is exposed in the long hole when the slide cover is in the retracted position are provided on the abutment surface of the operating part on the pillar member .

According to the present invention, at least one of the column members is formed by folding a strip-shaped metal plate extending in the vertical direction, and has a first bent portion bent outward in the left-right direction, a second bent portion bent outward in the front-rear direction from the first bent portion, a third bent portion bent inward in the left-right direction from the second bent portion, and a fourth bent portion bent inward in the front-rear direction from the third bent portion, and the space surrounded by the first bent portion, the second bent portion, the third bent portion, and the fourth bent portion is used as a space for passing wires. In addition, at least one of the second bent portion and the third bent portion has a wire passing hole communicating with the space. Therefore, it is possible to pull out the cable from the wire passing hole at the front or rear of the electrical equipment storage box without passing the cable through the gap between the various equipment and the side panel as in the conventional case, and the workability of passing the cable can be improved.
In addition , a slit extending in the vertical direction is provided near the wire passage hole, and a slide cover having a plate-shaped cover body and an operating part formed by bending an end of the cover body is attached to the pillar member with the operating part protruding to the outside of the pillar member through the slit and abutting the surface of the pillar member . The slide cover can be slid in the vertical direction along the slit between a cover position where the cover body closes the wire passage hole and a retracted position where the wire passage hole is opened. Therefore, it is possible to open only the necessary wire passage holes depending on the actual wire passage situation, and the wire passage holes can be opened without removing the slide cover from the pillar member, making it very easy to use.
Furthermore, the operating part is provided with a long hole that is long in the vertical direction, while the abutting surface of the pillar member with the operating part is provided with a round hole that is exposed in the long hole when the sliding cover is in the covering position, and a round hole that is exposed in the long hole when the sliding cover is in the retracted position. Therefore, for example, by inserting a pin member into the round hole via the long hole, the sliding cover can be held in the covering position or the retracted position.

Of the four pillar members 4, 4, which make up the rack 1, we will explain the pillar member 4 at the front left corner. The pillar member 4 comprises a pillar body 21 made of a strip-shaped metal plate that is long in the vertical direction, an upper reinforcing bracket 22 fixed to the upper end of the pillar body 21, and a lower reinforcing bracket 23 fixed to the lower end of the pillar body 21. The pillar body 21 is formed by bending the metal plate as described above, and has a first bent portion 21a bent to the left (outside in the left-right direction), a second bent portion 21b bent to the front (outside in the front-to-back direction) from the bent portion 21a, a third bent portion 21c bent to the right (inside in the left-to-right direction) from the bent portion 21b, a fourth bent portion 21d bent to the rear (inside in the front-to-back direction) from the bent portion 21c, and a fifth bent portion 21e bent to the left (outside in the left-to-right direction) from the bent portion 21d. In addition, wire passing holes 24 for passing wires are opened at a position near the top in the vertical direction in the bent portion 21b of the pillar body 21 and a position near the bottom in the vertical direction, respectively. Furthermore, slits 25 extending in the vertical direction are provided at the ridge between bent portions 21b and 21c in front of each wire passage hole 24. The upper portion of each slit 25 extends sufficiently upward beyond the corresponding wire passage hole 24. The front-to-rear width of bent portion 21b is wider than the front-to-rear width of bent portion 21d. The left-to-right width of bent portion 21c is wider than the left-to-right width of bent portion 21a, and the left-to-right width of bent portion 21a is wider than the left-to-right width of bent portion 21e.

On the other hand, the upper reinforcing metal fitting 22 is made by bending a metal plate, and includes a first reinforcing part 22a that abuts against the front (inner surface) of the bent part 21a when fixed to the column body 21, a second reinforcing part 22b that abuts against the right surface (inner surface) of the bent part 21b, a third reinforcing part 22c that abuts against the rear surface of the bent part 21e, and a fourth reinforcing part 22d that is fixed to the frame member that constitutes the top frame 3. The lower reinforcing metal fitting 23 is also made by bending a metal plate like the upper reinforcing metal fitting 22, and includes a first reinforcing part 23a that abuts against the front (inner surface) of the bent part 21a when fixed to the column body 21, a second reinforcing part 23b that abuts against the right surface (inner surface) of the bent part 21b, a third reinforcing part 23c that abuts against the rear surface of the bent part 21e, and a fourth reinforcing part 23d that is fixed to the frame member that constitutes the bottom frame 2.

In addition, two slide covers 10, 10 for opening and closing the wire holes 24, 24 are attached to the column member 4 as described above. The slide cover 10 comprises a plate-shaped cover body 10a having a thickness that allows it to be inserted into the slit 25, and an operation part 10b (protruding in the left and right direction from the cover body 10a) formed by bending the front end of the cover body 10a. The slide cover 10 is attached to the column member 4 with the cover body 10a inserted into the slit 25, the cover body 10a abutting against the right surface (inner surface) of the bent part 21b, and the operation part 10b abutting against the front surface (surface) of the bent part 21c. The slide cover 10 in the attached state is slidable in the vertical direction along the slit 25, and can be moved between a cover position where the cover body 10a blocks the wire holes 24 and a retracted position above the cover position where the wire holes 24 are opened. The operating section 10b has a long hole 10c (shown in FIG. 8) that is long in the vertical direction, while round holes 26, 26... (shown in FIG. 8) are drilled in the bent section 21c at positions that can be exposed within the long hole 10c. By inserting a pin member (not shown) into the round hole 26 via the long hole 10c, the slide cover 10 can be held in the cover position or the retracted position.

In the above-mentioned pillar member 4, the space 30 (shown in Figure 4) surrounded by the bent portions 21a to 21e can be utilized as a space for passing wires. When wiring between an adjacent equipment storage rack, the sliding cover 10 can be slid to the retracted position to open the wire passing hole 24, and the cable passing through the space 30 can be pulled out via the wire passing hole 24.
The shape of the pillar member 4 in the right front corner is linearly symmetrical in the left-right direction to the pillar member 4 in the left front corner, the shape of the pillar member 4 in the left rear corner is linearly symmetrical in the front-to-back direction to the pillar member 4 in the left front corner, and the shape of the pillar member 4 in the right rear corner is rotated 180 degrees around the vertical axis to the pillar member 4 in the left front corner.

According to the rack 1 having the above-mentioned configuration, the column body 21 of the column member 4 has a first bent portion 21a formed by bending a strip-shaped metal plate extending in the vertical direction and bending it outward in the left-right direction, a second bent portion 21b bent outward in the front-rear direction from the first bent portion 21a, a third bent portion 21c bent inward in the left-right direction from the second bent portion 21b, and a fourth bent portion 21d bent inward in the front-rear direction from the third bent portion 21c. The space 30 surrounded by the first bent portion 21a, the second bent portion 21b, the third bent portion 21c, and the fourth bent portion 21d is used as a space for passing wires. In addition, the second bent portion 21b has wire passing holes 24, 24 that communicate with the space 30. Therefore, cables can be pulled out from the cable passage holes 24 at the front or rear of the rack 1 without having to pass them through the gaps between the various devices and the side panels as in the past, improving the workability of passing cables through them.

In addition, a slit 25 extending in the vertical direction is provided at a location (near the wire-passing hole 24) in front of each wire-passing hole 24 on the ridge line between the bent portion 21b and the bent portion 21c, and the slide cover 10 having a plate-shaped cover body 10a and an operating part 10b protruding from the cover body 10a is attached to the column member 4 with the operating part 10b protruding to the front side of the column member 4 through the slit 25. The slide cover 10 can be slid in the vertical direction along the slit 25 between a cover position where the cover body 10a closes the wire-passing hole 24 and a retracted position where the wire-passing hole 24 is opened. Therefore, only the necessary wire-passing holes 24 can be opened according to the actual wire-passing situation, and the wire-passing holes 24 can be opened without removing the slide cover 10 from the column member 4, making it very easy to use.

Furthermore, an upper reinforcing bracket 22 having a first reinforcing portion 22a, a second reinforcing portion 22b, and a third reinforcing portion 22c is fixed to the upper end of the pillar body 21, and a lower reinforcing bracket 23 having a first reinforcing portion 23a, a second reinforcing portion 23b, and a third reinforcing portion 23c is fixed to the lower end, so that even though the wire passage holes 24, 24 are opened, sufficient strength can be ensured for the pillar member 4.

The electrical equipment storage box according to the present invention is not limited to the above embodiment, and the overall configuration as well as the configuration of the pillar members and slide cover can be modified as necessary.

For example, in the above embodiment, a fifth bend portion is provided on the pillar body, but it is not necessary to provide this fifth bend portion, and there is no problem if it is provided only at the upper end or lower end of the pillar body to which the upper reinforcing bracket and the lower reinforcing bracket are fixed.
In addition, in the above embodiment, the wire passage hole is opened in the second fold portion, but the wire passage hole may be opened in the third fold portion, or it is also possible to open the wire passage hole in both (for example, the upper wire passage hole is opened in the second fold portion and the lower wire passage hole is opened in the third fold portion).

Furthermore, while in the above embodiment wire passage holes are provided in all pillar members, it is also possible to provide wire passage holes only in the front pillar members, and it goes without saying that the design can be modified as to how many wire passage holes are provided in each pillar member.
Furthermore, in the above embodiment, a slit is provided on the ridge between the second and third folding portions, but a slit may be provided in the second or third folding portion, and the slide cover can be designed as appropriate, for example, by configuring the operating portion to protrude laterally from the side surface of the pillar member.

Furthermore, a bolt hole to be used as a so-called hanging bolt hole may be drilled in the fourth reinforcing portion of the upper reinforcing metal fitting, or a so-called anchor hole may be drilled in the fourth reinforcing portion of the lower reinforcing metal fitting, etc. By adopting such a configuration, it is possible to reduce the number of parts.
In the above embodiment, the bottom and top are each formed in a frame shape, but there is no problem if the bottom and top are formed in a plate shape.
Furthermore, in the above embodiment, the slide cover is slid upward from the cover position to be positioned at the retracted position, but it may be slid downward from the cover position to be positioned at the retracted position.
In addition, the present invention can also be suitably adopted for electrical equipment storage boxes other than equipment storage racks, as long as the box has a rectangular bottom and top when viewed from above, and the four corners are connected by pillar members.
