Description

The present invention relates to a rack for storing electrical and electronic equipment.

It is known to attach side frames to improve the strength of racks for storing electrical and electronic equipment. As disclosed in Patent Document 1, the side frames are attached to the right and left sides of the rack for storing electrical and electronic equipment so as to connect in the front-to-rear direction between two pairs of vertical frames. Conventionally, this has been achieved by inserting male screws into holes that penetrate in the front-to-rear direction to secure the rack in place.

JP 2012-156360 A

In the event of an earthquake, forces are applied to the rack for storing electrical and electronic equipment from multiple directions. In the event of an earthquake, forces may also be applied to the side frames. However, if the rack is fastened only with male screws extending in the front-to-rear direction, the side frames may come off due to forces from multiple directions.

The inventor of this case has thoroughly investigated this issue and attempted to solve it. The problem that this invention aims to solve is to make it difficult for the side frame to come off the vertical frame.

To solve the above problem, the rack for storing electrical and electronic equipment includes a housing whose skeleton is formed using vertical frames extending in the up-down direction, horizontal frames extending in the left-right direction, and depth frames extending in the front-rear direction, a mounting angle used to mount an equipment unit inside the housing, and a side frame attached to connect two vertical frames positioned at a distance in the front-rear direction, and the side frame is fixed to the vertical frame at a height between the depth frame located above and the depth frame located below from multiple directions including at least a direction parallel to the horizontal frame and a direction parallel to the depth frame.

It is also preferable that the side frame has multiple surfaces, with a main surface having the largest area among the surfaces in the side frame, and an opposing surface positioned opposite the main surface with a gap therebetween.

It is also preferable that the side frame has multiple surfaces, a main surface having the largest area among the surfaces in the side frame, and a reinforcing surface formed to rise from the main surface, and that the reinforcing surface is provided to rise from each of the upper, lower, front, and rear parts of the main surface.

It is also preferable that the side frame is further fixed to the mounting angle.

It is also preferable to position the side frame in a notch provided in the mounting angle.

It is also preferable that the frame of the housing is formed by connecting front and rear frames formed by two vertical frames and two horizontal frames, top and bottom frames formed by two depth frames, and two mounting brackets.

The present invention makes it possible to prevent the side frame from coming off the vertical frame.

The following is an embodiment of the invention. The rack 1 for storing electrical and electronic equipment of this embodiment includes a housing in which a skeleton 1a is formed using vertical frames 11 extending in the up-down direction, horizontal frames 12 extending in the left-right direction, and depth frames 13 extending in the front-rear direction, a mounting angle 14 used to mount an equipment unit in the housing, and a side frame 15 attached to connect the two vertical frames 11 positioned at a distance in the front-rear direction. The side frame 15 of this rack 1 for storing electrical and electronic equipment is fixed to the vertical frame 11 from multiple directions including at least a direction parallel to the horizontal frame 12 and a direction parallel to the depth frame 13 at a height between the depth frame 13 located above and the depth frame 13 located below. This makes it possible to prevent the side frame 15 from coming off the vertical frame 11.

As can be seen from Figs. 1 to 3, the rack 1 for storing electrical and electronic equipment shown in Fig. 1 has a skeleton 1a formed into a rectangular parallelepiped shape using vertical frames 11, horizontal frames 12, and depth frames 13. Panels 1c and doors 1b are attached to the skeleton 1a, which together form the main part of the external shape of the rack 1 for storing electrical and electronic equipment. In the example shown in Fig. 1, the vertical frames 11, horizontal frames 12, and parts of the depth frames 13 also form the external shape.

The skeleton 1a of the embodiment is constructed by combining a front frame body A, a rear frame body B, a top frame body C, and a bottom frame body D, each of which is configured in a rectangular frame shape (see FIG. 4). More specifically, the skeleton 1a of the embodiment is formed by the front frame body A and the rear frame body B, which are formed by two vertical frames 11 and two horizontal frames 12, and the top frame body C and the bottom frame body D, which are formed by two depth frames 13 and two mounting brackets 16. This configuration makes it easier to assemble the skeleton 1a. It also makes it easier to ensure strength.

Each frame forming the skeleton 1a has an opening, but a door 1b or panel 1c is attached to roughly close the opening, forming a closed space. In this embodiment, a door 1b that can close the opening penetrating in the front-rear direction is attached to the front frame A and the rear frame B, and a panel 1c is attached to the other surface of the rectangular skeleton 1a. As a result, all six surfaces are covered by either the door 1b or the panel 1c.

As can be seen from Figures 2 and 3, the rack 1 for storing electrical and electronic equipment of the embodiment is provided with a mounting angle 14 used for mounting an equipment unit inside the housing. The mounting angle 14 is arranged so as to be located closer to the center of the rack 1 for storing electrical and electronic equipment than the vertical frame 11 in a plan view. The mounting angle 14 of the embodiment is configured so that a cross section cut perpendicular to the longitudinal direction (a cross section cut in the horizontal direction) is approximately S-shaped.

The rack 1 for storing electrical and electronic equipment according to the embodiment also includes a side frame 15 that is attached to connect the two vertical frames 11. The side frame 15 connects the vertical frames 11 together, thereby reinforcing the framework 1a (see Figures 5 to 7).

As can be seen from FIG. 2, the position where the side frame 15 is attached is a position that spans between the two paired vertical frames 11 on the right and left sides of the rack 1 for storing electrical and electronic equipment in the front-to-rear direction. In the left-to-right direction, it is a position between the panels 1c that form the left and right sides and the mounting angle 14. In the up-down direction, it is a position between the two paired depth frames 13 on the upper and lower sides.

The side frame 15 is preferably attached below the center of gravity of the rack 1 for storing electrical and electronic equipment. This makes it possible to more effectively improve the strength of the rack 1 for storing electrical and electronic equipment. The center of gravity may be calculated when no equipment units are mounted, or when the equipment units are mounted.

As can be seen from FIG. 7, it is preferable that the side frames 15 are fixed to the vertical frames 11 in at least two directions, the front-to-back direction and the left-to-right direction. This improves the strength of the rack 1 for storing electrical and electronic equipment against vibrations in the front-to-back and left-to-right directions.

The side frame 15 is preferably also fixed to the mounting angle 14. This increases the strength of the rack 1 for storing electrical and electronic equipment in the left-right direction. For this reason, the side frame 15 of the embodiment is provided with mounting holes 15h that are used for mounting to the mounting angle 14 (see Figures 5 to 7).

In the actual embodiment, the side frame 15 has mounting holes 15h that penetrate in the left-right direction and correspond in the front-rear direction to the mounting holes Ch of the top frame C and the mounting holes Dh of the bottom frame D. In addition, multiple mounting holes 15h are formed in a line on the longitudinal side of the depth frame 13, making it possible to accommodate the movement of the mount angle 14 in the front-rear direction.

It is also preferable to provide the mount angle 14 with a notch 14a and position the side frame 15 in this notch 14a. In particular, it is preferable to form the notch 14a in the mount angle 14, whose vertical length is approximately the same as that of the side frame 15, and to arrange the side frame 15 so that a part of the side frame 15 is inserted into the notch 14a. In this way, the mount angle 14 can restrict the vertical movement of the side frame 15. This can improve the strength of the rack for storing electrical and electronic equipment 1 against vertical vibrations in the event of an earthquake or the like. In addition, if a part of the upper surface or lower surface of the side frame 15 abuts against the mount angle 14 during normal times, the vertical strength of the rack for storing electrical and electronic equipment 1 can also be improved. As can be understood from these descriptions, if at least a part of the upper surface or lower surface of the side frame 15 can be in contact with the mount angle 14 during normal times or in an emergency, the strength can be improved.

In the embodiment, the side frames 15 are fixed to both the frame 1a and the mounting angle 14 of the rack 1 for storing electrical and electronic equipment using screws. Note that in the embodiment, the side frames 15 are attached to the right and left sides of the frame 1a so as to connect two vertical frames 11 that are separated in the front-to-rear direction, but they may be provided on either the right or left side of the frame 1a.

Here, the front frame body A in the embodiment will be described. As can be seen from Figures 4 and 8, the front frame body A in the embodiment is formed of two vertical frames 11a and two horizontal frames 12a, and the ends of the vertical frames 11a and the horizontal frames 12a are connected via connecting fittings A1.

A mounting hole 11aah is formed on the front side of the vertical frame 11a, which is a component of the front frame A. A hinge for supporting the door 1b or a locked part (such as a rod receiver) that locks with a locking part of the handle (such as a rod) when a handle provided on the door 1b is operated, preventing the door 1b from rotating, can be attached to the mounting hole 11aah.

The rear side of the vertical frame 11a, which is a component of the front frame A, has a mounting hole 11abh formed therein, and this mounting hole 11abh can be used to attach the depth frame 13, mounting bracket 16, side frame 15, and other components of the top frame C or bottom frame D. In the example skeleton 1a shown in Figure 2, the depth frame 13 is screwed to the vertical frame 11 in a direction parallel to the horizontal frame 12, and the mounting bracket 16 is screwed to the vertical frame 11 in a direction parallel to the depth frame 13.

As can be seen from Figures 4 and 9, the rear frame B of the embodiment is formed of two vertical frames 11 and two horizontal frames 12, similar to the front frame A, and the ends of the vertical frames 11b and the horizontal frames 12b are connected via connecting fittings B1. A mounting hole 11bbh is formed on the rear side of the vertical frame 11b, which is a component of the rear frame B. This mounting hole 11bbh can be used to attach a hinge for supporting the door 1b, or a locked part (rod receiver, etc.) that is locked to a locking part of a handle (such as a rod) by operating a handle provided on the door 1b to prevent the door 1b from rotating.

A mounting hole 11bah is formed on the front side of the vertical frame 11b, which is a component of the rear frame B. This mounting hole 11bah can be used to attach the depth frame 13 or mounting bracket 16 that form the top frame C or bottom frame D, or the side frame 15.

The rear frame B of the embodiment is longer in the front-to-rear direction (depth direction) than the front frame A in order to secure space for wiring extending from the equipment unit attached to the mounting angle 14. In addition, the upper horizontal frame 12 forming the rear frame B has an opening for inserting wiring that connects the equipment unit to equipment outside the electrical and electronic equipment storage rack 1. However, this opening is closed by an opening panel when it is not necessary to insert wiring.

The top frame C of the embodiment is formed in a square shape in a plan view with two depth frames 13 and two mounting brackets 16 (see Figures 10 and 11). The ends of the depth frame 13 and the mounting brackets 16 are connected by welding. The depth frame 13 and the mounting brackets 16 may be fixed with fasteners such as screws, but fasteners are not necessary. For example, it is sufficient to simply engage the mounting brackets 16 with the depth frame 13 so that they are held in place.

The mounting bracket 16 of the top frame C in this embodiment is formed in a roughly U-shape so that it can fit along the two vertical frames 11 and one horizontal frame 12 of the front frame A or rear frame B, and each side has multiple fixing holes 16uh for fixing to the vertical frame 11 and horizontal frame 12 (see Figures 10 to 12). In addition, a bent edge 161 extending from the upper end toward the inside of the housing is provided on the surface parallel to the horizontal frame 12. A panel 1c covering the opening on the top side of the housing is attached from the outside of the housing so that it is supported by this bent edge 161 and the depth frame 13.

The inner surface of the housing of the depth frame 13 is provided with a mounting hole Ch for mounting the mount angle 14. If multiple mounting holes Ch are formed along the length of the depth frame 13, the mount angle 14 can be moved forward and backward.

The bottom frame D of the embodiment is formed of two depth frames 13 and two mounting brackets 16, similar to the top frame C (see Figures 13 and 14). The ends of the depth frame 13 and the mounting brackets 16 are connected by welding. The depth frame 13 and the mounting brackets 16 may be fixed with fasteners such as screws, but fasteners are not necessary. For example, it is sufficient to simply engage the mounting brackets 16 with the depth frame 13 so that they are held in place.

The mounting bracket 16 of the bottom frame D in this embodiment is formed in a roughly U-shape so that it can fit along the two vertical frames 11 and one horizontal frame 12 of the front frame A or rear frame B, and each side has multiple fixing holes 16dh for fixing to the vertical frame 11 and horizontal frame 12 (see Figures 13 and 15). In addition, a folded edge 162 is provided on the surface parallel to the horizontal frame 12, which is formed by folding multiple times from its lower end toward the inside of the housing. The panel 1c covering the opening on the bottom side of the housing is attached from the inside of the housing so that it is supported by this folded edge 162.

The mounting holes Dh for mounting the mount angle 14 are formed on the inner surface of the housing of the depth frame 13 so that their positions in the front-to-back direction correspond to the mounting holes Ch of the top frame body C. If multiple mounting holes Dh are formed in the longitudinal direction of the depth frame 13, the mount angle 14 can be moved in the front-to-back direction.

In the embodiment, the mount angle 14 is attached to the depth frame 13 located at the top of the skeleton 1a and the depth frame 13 located at the bottom (see Figure 16). When attaching the mount angle 14, it is preferable to create a wiring space between the mount angle 14 and the vertical frame 11 in order to place the wiring of the equipment unit, etc. For this reason, in the embodiment, a gap Ga is created between the mount angle 14 and the vertical frame 11 (see Figures 16 and 17).

In general, the rack 1 for storing electrical and electronic equipment takes in cooled air from the front side, cools the equipment units, and then expels heated air from the equipment units to the rear side. If this heated air returns to the front side through the gap Ga, the cooling efficiency of the equipment units will decrease. In order to ensure both wiring space and cooling efficiency, it is preferable to attach the mounting angle 14 so that a gap Ga is created between the mounting angle 14 and the vertical frame 11 located at the front, and to attach a shielding member to prevent heated air from moving from parts of this gap Ga that are not used as wiring space.

So far, we have explained how to attach the side frame 15 and an example of an electrical/electronic device storage rack 1 to which the side frame 15 is attached. The side frame 15, which functions as a reinforcement for the skeleton 1a, can be formed in a roughly plate shape to obtain the effect, but depending on the shape, the strength can be further improved. For example, the strength of the side frame 15 can be improved by configuring the side frame 15 to have multiple surfaces, with a main surface having the largest area among the surfaces of the side frame 15 and an opposing surface positioned to face the main surface at a distance. For example, it is preferable to configure the side frame 15 in a C-shaped cross section with the main surface and the opposing surface facing each other, like the shape of a lip channel steel (see Figures 18 and 19).

The strength of the side frame 15 can be improved by configuring the side frame 15 to have multiple surfaces, a main surface that has the largest area among the surfaces of the side frame 15, and reinforcing surfaces that are formed to rise from the main surface, and the reinforcing surfaces are provided to rise from the top, bottom, front, and rear of the main surface. In this case, the reinforcing surfaces rise on all four sides of the main surface, making it easier to exert a force that resists forces from multiple directions.

In the example shown in Figures 20 and 21, reinforcing surfaces are provided on the top, bottom, front, and rear of the rectangular main surface, and the reinforcing surfaces rise from almost the entire periphery of the main surface. Therefore, the main surface and reinforcing surfaces form a roughly box-like configuration. Note that, although the side frame 15 in the embodiment is formed by bending a metal plate to form multiple surfaces, it is not necessarily required to be bent.

To increase the strength of the side frame 15, it is preferable to configure the side frame 15 to have multiple faces, and it is particularly preferable to have three or more faces. It is also preferable to have multiple faces that rise perpendicular to the main face. It is also preferable to have a face that extends perpendicular to the face that rises perpendicular to the main face, forming a face that extends parallel to the main face. In any case, by increasing the strength of the side frame 15, it is possible to improve the strength of the rack 1 for storing electrical and electronic equipment to which it is attached.

It is also preferable for the side frame 15 to have a substantially rectangular parallelepiped shape. In this case, it is preferable to form an opening on one of the faces through which tools can be inserted so that the side frame 15 can be fixed to the vertical frame 11. There are no particular limitations on the shape or size of the opening.

The racks 1 for storing electrical and electronic equipment come in a variety of sizes. On the other hand, the distance between the mounting angles 14 on the left and right sides is usually uniform. Therefore, when the size of the rack 1 for storing electrical and electronic equipment changes, the distance between the mounting angles 14 and the vertical frame 11 also changes.

For this reason, when fixing the side frame 15 to the mounting angle 14, it is preferable to use a side frame 15 that matches the positional relationship between the vertical frame 11 and the mounting angle 14.

Here we explain an example of a side frame 15 that is used when the left-right size of the housing is small and the distance between the mounting angle 14 and the vertical frame 11 is very small (for example, when the distance is only the thickness of the side frame 15).

18 and 19, the side frame 15 has a first surface 1511 located on the inside of the housing where the mounting hole 15h for mounting the mount angle 14 is formed, a second surface 1512 and a third surface 1513 formed by bending the upper and lower ends of the first surface 1511 toward the outside of the housing, a fourth surface 1514 and a fifth surface 1515 formed by bending the front and rear ends of the second surface 1512 upward, and a sixth surface 1516 and a seventh surface 1517 formed by bending the front and rear ends of the third surface 1513 downward. The side frame 15 is configured to have a three-dimensional shape by having these surfaces, but in the example shown in FIG. 18 and FIG. 19, the first surface 1511 to the third surface 1513 are configured to be approximately U-shaped. In addition, an eighth surface 1518 is provided from the second surface 1512 so as to face the first surface 1511 with a gap therebetween. A ninth surface 1519 is provided from the third surface 1513 so as to face the first surface 1511 with a gap therebetween.

The first surface 1511 is the main surface with the largest area among the surfaces of the side frame 15, and is the part that abuts the left-right surfaces of the vertical frame 11, and is provided with a first fixing hole h1h. The side frame 15 in this example is fixed to the vertical frame 11 using this first fixing hole h1h, thereby fixing from the left-right direction. Note that the mounting hole 15h and the first fixing hole h1h can be shared, and the side frame 15 may be fixed to the vertical frame 11 via the mounting hole 15h.

The fourth surface 1514, the fifth surface 1515, the sixth surface 1516, and the seventh surface 1517 abut against the surfaces of the vertical frame 11 that extend in the up-down and left-right directions, and are provided with second fixing holes h2h. Fixing to the vertical frame 11 through these second fixing holes h2h allows fixing from the front-to-rear direction. It is preferable that the size of the side frame 15 in the left-to-right direction is approximately the same as that of the depth frame 13. In addition, the eighth surface 1518 and the ninth surface 1519, which are positioned to face the first surface 1511, which is the main surface, at a distance, are the opposing surfaces.

Next, we will explain an example of a side frame 15 that is used when the left-right size of the housing is relatively large and there is a certain distance between the mounting angle 14 and the vertical frame 11 (for example, when there is a distance equal to or greater than the plate thickness of the side frame 15).

The side frame 15 shown in Figures 20 and 21 has a first surface 1521 located on the inside of the housing where the mounting hole 15h for mounting the mount angle 14 is formed, a second surface 1522 and a third surface 1523 formed by bending the upper and lower ends of the first surface 1521 toward the outside of the housing, a fourth surface 1524 and a fifth surface 1525 formed by bending the front and rear ends of the first surface 1521 toward the outside of the housing, and an end of the fourth surface 1524 parallel to the first surface 1521. 20 and 21, the side frame 15 is configured to have a three-dimensional shape, and the side frame 15 is configured so that the second surface 1522 to the fifth surface 1525 form a rectangular shape. The side frame 15 is configured so that the second surface 1522 to the fifth surface 1525 form a rectangular shape. The side frame 15 is configured so that the second surface 1522 to the fifth surface 1525 form a rectangular shape.

The sixth surface 1526 and the eighth surface 1528 are portions that abut against the left and right surfaces of the vertical frame 11, and are provided with first fixing holes h1h. The side frame 15 is fixed to the vertical frame 11 using the first fixing holes h1h. In the example shown in FIG. 20 and FIG. 21, the first surface 1521 is located on the inner side of the housing than the sixth surface 1526 and the eighth surface 1528, and therefore the first surface 1521 is provided with an opening 1520 through which the first fixing holes h1h provided in the sixth surface 1526 and the eighth surface 1528 can be seen. The first fixing holes h1h can be accessed by inserting a tool or the like into this opening 1520.

The seventh surface 1527 and the ninth surface 1529 are portions that abut against the front-rear surfaces of the vertical frame 11, and are provided with second fixing holes h2h. The side frame 15 is fixed to the vertical frame 11 using these second fixing holes h2h. In the example shown in Figures 20 and 21, the space between the outer end of the second surface 1522 and the outer end of the third surface 1523 is open. The second fixing holes h2h can be accessed by inserting a tool or the like into this portion.

The first surface 1521 is the main surface with the largest area among the surfaces in the side frame 15, and the second surface 1522, third surface 1523, fourth surface 1524, and fifth surface 1525, which are formed to rise from the first surface 1521, which is the main surface, serve as reinforcing surfaces. In addition, the sixth surface 1526 and eighth surface 1528, which are positioned to face the first surface 1521, which is the main surface, at a distance, serve as opposing surfaces.

An example of attaching the side frame 15 shown in Fig. 20 and Fig. 21 to the vertical frame 11 is shown in Fig. 22 and Fig. 23. Note that Fig. 22 and Fig. 23 also show the shielding member Sh. Fig. 24 shows these disassembled.

In this example, the shielding member Sh, which prevents air from entering or exiting between the mounting angle 14 and the vertical frame 11, is plate-shaped. As can be seen from FIG. 25, the shielding member Sh is attached to the mounting angle 14. The shielding member Sh is not fixed to the vertical frame 11. This allows the mounting angle 14 to move in the forward and backward directions with the shielding member Sh attached. Although not shown in FIG. 25, one end of the shielding member Sh (the end not adjacent to the mounting angle 14) is actually adjacent to the panel 1c, allowing it to fully function.

As can be seen from FIG. 26, the side frame 15 in this example is also screwed to the vertical frame 11 so as to be tightened in the front-to-back and left-to-right directions.

The present invention has been described above using examples of embodiments, but the present invention is not limited to the above embodiments and can be implemented in various forms.
