[0016] The multiple support members 31 are provided at intervals in the vertical direction Dv. For example, four support members 31 according to the present disclosure are provided at intervals in the vertical direction Dv. The number of support members 31 is not limited to four, and may be two, three, five or more. Of the multiple support members 31, the lowest support member 31 is attached to the upper side of both ends of the bottom plate portion 21A in the width direction Dw. Of the multiple support members 31, the uppermost support member 31 is attached to the lower side of both ends of the top plate portion 22A in the width direction Dw.

[0017] Each support member 31 extends along the front-rear direction Da. Each support member 31 has a shaft support hole (not shown) at one end in the front-rear direction Da. The shaft support hole penetrates the support member 31 in the width direction Dw. Each support member 31 has a slide hole 31h at the other end in the front-rear direction Da. The slide hole 31h penetrates the support member 31 in the width direction Dw and extends in the front-rear direction Da. In addition, support plates 31p that protrude inward in the width direction Dw are provided at both ends of each support member 31 in the front-rear direction Da.

[0018] A plurality of pairs of first link members 32 and second link members 33 are provided between the upper and lower support members 31. For example, three pairs of the first link members 32 and second link members 33 of the present disclosure are provided in the up-down direction Dv.

[0019] One end 32a of each set of first link members 32 is rotatably supported in one of the pivot holes (not shown) of the upper and lower support members 31. The other end 32b of each set of first link members 32 is slidably supported in the front-to-rear direction Da in the other slide hole 31h of the upper and lower support members 31. One end 32a of the first link member 32 of the present disclosure is rotatably supported in the pivot hole (not shown) of the upper support member 31. The other end 32b of the first link member 32 of the present disclosure is slidably supported in the front-to-rear direction Da in the slide hole 31h of the lower support member 31.

[0020] One end 33a of each pair of second link members 33 is rotatably supported in the other pivot support hole (not shown) of the upper or lower support member 31. The other end 33b of each pair of second link members 33 is slidably supported in the front-to-rear direction Da in one of the slide holes 31h of the upper or lower support member 31. One end 33a of the second link member 33 of the present disclosure is rotatably supported in the pivot support hole (not shown) of the lower support member 31. The other end 33b of the second link member 33 of the present disclosure is slidably supported in the front-to-rear direction Da in the slide hole 31h of the upper support member 31.

[0021] One end 32a of the first link member 32 and one end 33a of the second link member 33, which are supported in the same pivot hole, are provided coaxially. The other end 32b of the first link member 32 and the other end 33b of the second link member 33, which are supported in the same slide hole 31h, are provided coaxially. The center portion of the first link member 32 and the center portion of the second link member 33 in each pair are rotatably connected to each other.

[0022] In this telescoping mechanism 3A, each of the multiple pairs of first link members 32 and second link members 33 rotates around one end 32a, 33a, and the other ends 32b, 33b slide along the slide holes 31h, thereby telescoping in the vertical direction Dv. The telescoping mechanism 3A telescopes, for example, by an operator moving the top plate 22A up and down relative to the bottom plate 21A. A hydraulic jack, for example, may be used to move the top plate 22A up and down relative to the bottom plate 21A. Furthermore, when viewed from above, the extension mechanism 3A, in its contracted state, is accommodated inside the area overlapping the top plate portion 22A and the bottom plate portion 21A, that is, within the internal area of ​​the electronic equipment rack 2A.

[0023] The restraining portion 4A is provided between the bottom plate portion 21A and the top plate portion 22A. As shown in FIG. 1, the restraining portion 4A can restrain a pair of extension mechanisms 3A on both sides in the width direction Dw in an extended state. The restraining portion 4A is provided on both sides in the width direction Dw. The restraining portion 4A of the present disclosure includes a plate-shaped member 41 and a fixing portion 42 (see FIG. 4).

[0024] A plurality of plate-like members 41 are arranged in the vertical direction Dv. For example, three plate-like members 41 according to the present disclosure are arranged in the vertical direction Dv. The plurality of plate-like members 41 are arranged on the inside in the width direction Dw with respect to each of the extension mechanisms 3A on both sides in the width direction Dw.

[0025] Either the upper end or the lower end of each plate-shaped member 41 is supported by the support member 31 so as to be rotatable about an axis extending in the front-rear direction Da. Each plate-shaped member 41 of the present disclosure is supported by its upper end so as to be rotatable about an axis extending in the front-rear direction Da. The upper end of each plate-shaped member 41 of the present disclosure is supported at both ends in the front-rear direction Da by support plates 31p provided at both ends in the front-rear direction Da of the support member 31 so as to be rotatable about an axis extending in the front-rear direction Da.

[0026] 1, when the telescoping mechanism 3A is extended to separate the bottom plate 21A and the top plate 22A vertically and the electronic equipment rack 2A is unfolded, each plate member 41 stands upright along a plane intersecting the width direction Dw. In this state, the multiple plate members 41 are stacked vertically, thereby restraining the bottom plate 21A and the top plate 22A in a state where they are separated at a predetermined interval in the vertical direction Dv.

[0027] Also, as shown in Figure 3, when the telescopic mechanism 3A is shortened to bring the bottom plate portion 21A and the top plate portion 22A closer together in the vertical direction and the electronic equipment rack 2A is folded, each plate-like member 41 falls along a plane that intersects with the vertical direction Dv.

[0028] The plate-like member 41 may have its lower end rotatably supported by the support member 31. However, if the plate-like member 41 has its upper end rotatably supported by the support member 31, as shown in Fig. 2, when the electronic equipment rack 2A is unfolded from the folded state, the plate-like member 41 can stand up by its own weight from the state along the horizontal plane.

[0029] FIG. 4 is a perspective view showing a plate-shaped member 41 of the present disclosure. As shown in FIG. 4, the plate-like member 41 has pillar-like portions 41c extending in the up-down direction Dv at both ends in the front-rear direction Da. The fixing portions 42 are provided on the columnar portions 41c at both ends of the plate-like members 41 in the front-rear direction Da. The fixing portions 42 fix the multiple plate-like members 41 along a plane including the up-down direction Dv. The fixing portions 42 connect the plate-like members 41 positioned above and below each other. The fixing portions 42 have connection pins 42p and insertion holes 42h.

[0030] The connection pins 42p are provided at either the upper end or the lower end of the plate-like member 41. The connection pins 42p protrude toward the other plate-like members 41 located above or below. In the present disclosure, the plate-like member 41 on one side in the width direction Dw has the connection pins 42p protruding downward from the lower end of the columnar portion 41c. In the present disclosure, the plate-like member 41 on the other side in the width direction Dw has the connection pins 42p protruding upward from the upper end of the columnar portion 41c.

[0031] The insertion holes 42h are provided at the other of the upper end and lower end of the plate-like member 41. The connection pins 42p of another plate-like member 41 located above or below can be inserted into the insertion holes 42h. In the present disclosure, the plate-like member 41 on one side in the width direction Dw has the insertion holes 42h recessed downward from the upper ends of the columnar portions 41c. In the present disclosure, the plate-like member 41 on the other side in the width direction Dw has the insertion holes 42h recessed upward from the lower ends of the columnar portions 41c.

[0032] FIG. 5 is a perspective view showing a state in which the connection pins of one plate-like member are inserted into the insertion holes of the other plate-like member in the unfolded state of the electronic equipment rack of the present disclosure. 5, when the electronic equipment rack 2A is unfolded, the connection pins 42p of one of the plate-like members 41 positioned above and below each other are inserted into the insertion holes 42h of the other plate-like member 41. As a result, the multiple plate-like members 41 stand up along a plane intersecting the width direction Dw, and are fixed in a stacked state in the vertical direction.

[0033] FIG. 6 is a perspective view showing a state in which the connection pins of one plate-like member are inserted into the insertion holes of the other plate-like member when the electronic equipment rack of the present disclosure is in a folded state. 6, when the electronic equipment rack 2A is folded, the connection pins 42p of the plate-like members 41 on one side in the width direction Dw are inserted into the insertion holes 42h of the plate-like members 41 on the other side in the width direction Dw. As a result, the plate-like members 41 on one side in the width direction Dw and the plate-like members 41 on the other side in the width direction Dw are fixed in a fallen state along a plane intersecting with the up-down direction Dv.

[0034] 1, each plate-like member 41 has an equipment support portion 41g on a surface facing inward in the width direction Dw. The equipment support portion 41g of the present disclosure is, for example, a guide rail extending in the front-rear direction Da. The equipment support portion 41g is capable of supporting the electronic device 100 mounted on the electronic device rack 2A. The equipment support portion 41g is capable of supporting, for example, both ends in the width direction Dw of the plate-like mounting member 110 on which the electronic device 100 is placed. The equipment support portion 41g may be configured to support, for example, brackets (not shown) provided on both sides of the electronic device 100 in the width direction Dw.

[0035] Examples of the electronic devices 100 supported by the device support portion 41g include a server, a switch device, a data logger, etc. The electronic device rack 2A may also be provided with various interface devices for connecting the mounted electronic devices 100.

[0036] FIG. 7 is a diagram showing the flow of the installation method for the electronic equipment rack 2A of the present disclosure. As shown in FIG. 7, the method for installing the electronic device rack 2A of the present disclosure includes a step S11 of folding the electronic device rack 2A, a step S12 of transporting the electronic device rack 2A to the installation location, and a step S13 of installing the electronic device rack 2A at the installation location.

[0037] In step S11 of folding the electronic equipment rack 2A, the electronic equipment rack 2A is folded as shown in FIG. 3 before the electronic equipment 100 is carried into the installation location. To do this, as shown in FIG. 2, a pair of extension mechanisms 3A are contracted between the bottom plate portion 21A and the top plate portion 22A of the electronic equipment rack 2A, bringing the bottom plate portion 21A and the top plate portion 22A closer to each other. As a result, as shown in FIG. 3, each plate-like member 41 is tilted and positioned along a plane intersecting the vertical direction Dv. Furthermore, as shown in FIG. 6, the connection pins 42p of the plate-like member 41 on one side in the width direction Dw are inserted into the insertion holes 42h of the plate-like member 41 on the other side in the width direction Dw. This brings the electronic equipment rack 2A into the folded state.

[0038] In step S12 of carrying the electronic equipment rack 2A into the installation location, the electronic equipment rack 2A in the folded state is carried into the installation location of the electronic equipment rack 2A. At this time, since the electronic equipment rack 2A is in the folded state, it can pass through entrances and exits that would be difficult to pass through if the electronic equipment rack 2A was in the unfolded state.

[0039] Then, in step S13 of installing the electronic equipment rack 2A at the installation location, as shown in FIGS. 2 and 1, the pair of extension mechanisms 3A are extended to separate the bottom plate portion 21A and the top plate portion 22A. This causes each plate-like member 41 to stand upright. With the electronic equipment rack 2A in an unfolded state, as shown in FIG. 5, the connection pin 42p of one of the plate-like members 41 positioned above and below each other is inserted into the insertion hole 42h of the other plate-like member 41. As a result, as shown in FIG. 1, the multiple plate-like members 41 stand upright along a plane intersecting the width direction Dw and are fixed in a vertically stacked state. In this way, the electronic equipment rack 2A is unfolded. The electronic equipment rack 2A is installed at a predetermined installation location.

[0040] The electronic equipment rack 2A of this embodiment includes a pair of extension mechanisms 3A and a restraining unit 4A that can restrain the pair of extension mechanisms 3A in an extended state. Therefore, the electronic equipment rack 2A can be folded by contracting the pair of extension mechanisms 3A. This makes it easy to transport the electronic equipment rack 2A to the installation location. Furthermore, multiple electronic equipment racks 2A in the folded state can be stacked for transportation. Furthermore, after being transported to the installation location, the pair of extension mechanisms 3A are extended and restrained by the restraining section 4A, thereby maintaining the electronic equipment rack 2A in an expanded state and allowing the electronic equipment 100 to be stably mounted.

[0041] The restraining portion 4A of the electronic equipment rack 2A of this embodiment includes a plate-shaped member 41 and a fixing portion 42 that fixes the plate-shaped member 41 in a state along a plane including the up-down direction Dv. Therefore, when the electronic equipment rack 2A is unfolded, the pair of extension mechanisms 3A can be restrained in an extended state.

[0042] The fixing portions 42 of the electronic equipment rack 2A of this embodiment connect the upper and lower plate-like members 41. Therefore, when the electronic equipment rack 2A is unfolded, the multiple plate-like members 41 are connected, and the pair of extension mechanisms 3A can be restrained in an extended state.

[0043] The fixing portions 42 of the electronic equipment rack 2A of this embodiment connect the plate-like members 41 on one side in the width direction Dw and the plate-like members 41 on the other side in the width direction Dw, which are aligned along a plane intersecting the up-down direction Dv. When the electronic equipment rack 2A is folded, the plate-like members 41 on one side in the width direction Dw and the plate-like members 41 on the other side in the width direction Dw can be connected to each other.

[0044] The restraining portion 4A of the electronic equipment rack 2A of this embodiment is provided on the inner side in the width direction Dw of the pair of extension mechanisms 3A. Therefore, the pair of extension mechanisms 3A and the restraining portion 4A can form the side wall portion 23 of the electronic equipment rack 2A.

[0045] The extension mechanism 3A of the electronic equipment rack 2A of this embodiment includes a support member 31, a first link member 32, and a second link member 33. Therefore, the extension mechanism 3A has a so-called pantograph-like configuration, and is easily extendable and retractable in the vertical direction.

[0046] In the electronic equipment rack 2A of this embodiment, either the upper end or the lower end of the plate-shaped member 41 is supported by the support member 31 so as to be rotatable about an axis. This eliminates the need for a special member to support the plate-shaped member 41, and allows the extension / retraction mechanism 3A and the restraint unit 4A to be provided while reducing the number of parts.

[0047] The plate-like member 41 of the electronic equipment rack 2A of this embodiment has an equipment support portion 41g, which allows the electronic equipment 100 to be mounted on the electronic equipment rack 2A.

[0048] The electronic equipment unit 1A of this embodiment includes an electronic equipment rack 2A and an electronic device 100. This makes it possible to provide an electronic equipment unit 1A equipped with an electronic equipment rack 2A that can be easily carried into an installation location.

[0049] According to the installation method of the electronic equipment rack 2A of this embodiment, the electronic equipment rack 2A can be installed in a manner that allows it to be easily transported to the installation location.

As shown in FIG. 8, an electronic equipment rack 2B of the present disclosure includes a bottom plate portion 21B, a top plate portion 22B, a pair of extension mechanisms 3B, and a restraint portion 4B. The top plate portion 22B is provided above and spaced from the bottom plate portion 21B. The pair of extension mechanisms 3B are provided between the bottom plate portion 21B and the top plate portion 22B at an interval in the width direction Dw. Each of the pair of extension mechanisms 3B is extendable and contractible in the up-down direction Dv. The restraining portion 4B is provided between the bottom plate portion 21B and the top plate portion 22B. The restraining portion 4B is capable of restraining the pair of extension mechanisms 3B in an extended state.

[0051] The electronic equipment rack 2B of this embodiment includes a pair of extension mechanisms 3B and a restraining unit 4B that can restrain the pair of extension mechanisms 3B in an extended state. Therefore, the electronic equipment rack 2B can be folded by contracting the pair of extension mechanisms 3B. This makes it easy to transport the electronic equipment rack 2B to the installation location. After transporting the electronic equipment rack 2B to the installation location, the pair of extension mechanisms 3B can be restrained by the restraining unit 4B in an extended state, thereby maintaining the electronic equipment rack 2B in an unfolded state and allowing the electronic equipment 100 to be stably mounted.
