[0011] Hereinafter, the cabinet and tray according to the embodiment will be described in detail with reference to the drawings. However, the figures described in the following embodiments are schematic diagrams, and the dimensional ratios of the size of each component do not necessarily reflect the actual dimensional ratios. Furthermore, the configuration described in the following embodiments is merely one example of this disclosure. This disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of this disclosure can be achieved.

[0012] (Embodiment) (1) Overview First, the cabinet 1 and tray 2 according to this embodiment will be described with reference to Figure 1. As shown in Figure 1, the cabinet 1 comprises a first tray 2A and a second tray 2B. Each of the first tray 2A and the second tray 2B can accommodate multiple (three in the illustrated example) storage batteries 100 (see Figure 11). As shown in Figure 1, the cabinet 1 is configured so that the second tray 2B can be stacked on top of the first tray 2A. The cabinet 1 according to this embodiment is suitable for storing six storage batteries 100.

[0013] The first tray 2A and the second tray 2B are used in the cabinet 1. Each of the first tray 2A and the second tray 2B according to this embodiment can accommodate three batteries 100, making them suitable for storing multiple (in this case, three) batteries 100 (see Figure 11).

[0014] (2)Details Next, the cabinet 1 and the tray 2 according to the embodiment will be described in detail with reference to FIGS.

[0015] In the following description, the X-axis direction in Figures 1 to 9 and the like is defined as the left-right direction, the Y-axis direction as the front-rear direction (depth direction), and the Z-axis direction as the up-down direction. The front-rear direction corresponds to the "direction in which the storage batteries are removed" in this disclosure. The left-right direction corresponds to the "direction in which the storage batteries are arranged" in this disclosure. Furthermore, the positive direction in the X-axis direction is defined as the right, the positive direction in the Y-axis direction as the front, and the positive direction in the Z-axis direction as the up.

[0016] However, these directions are merely examples and are not intended to limit the directions in use of the cabinet 1 and the tray 2. Also, the arrows indicating the directions in the drawings are merely shown for the purpose of explanation and have no substance.

[0017] (2.1) Cabinet FIG. 1 is a perspective view of a cabinet 1 according to an embodiment, as seen from the diagonally front right. FIG. 2 is a perspective view of the cabinet 1 as seen from the diagonally rear left. As shown in FIG. 1, the cabinet 1 includes a first tray 2A and a second tray 2B that can be stacked on top of the first tray 2A. That is, the cabinet 1 of this embodiment can be assembled by stacking the second tray 2B on top of the first tray 2A. In this disclosure, the "first tray 2A" refers to a tray located below the cabinet 1 with respect to the second tray 2B (in the negative direction of the Z axis in the figure). In this disclosure, the "second tray 2B" refers to a tray located above the cabinet 1 with respect to the first tray 2A (in the positive direction of the Z axis in the figure).

[0018] In this embodiment, the first tray 2A and the second tray 2B have the same shape. Note that "same" in this disclosure does not only mean a perfect match, but also includes being substantially the same. Being substantially the same includes an allowable degree of error (tolerance).

[0019] Hereinafter, when there is no need to particularly distinguish between the first tray 2A and the second tray 2B, they will be simply referred to as tray 2. In this embodiment, as shown in Figures 7 and 9, the tray 2 is configured to be symmetrical in the front-to-rear direction (the Y-axis direction in the figures) and in the left-to-right direction (the X-axis direction in the figures).

[0020] (2.2) Tray FIG. 3 is a perspective view of the tray 2 as seen from the diagonally front right. FIG. 4 is a perspective view of the tray 2 as seen from the diagonally rear left. FIG. 5 is a front view of the tray 2. FIG. 6 is a side view of the tray 2. FIG. 7 is a plan view of the tray 2. FIG. 8 is a cross-sectional view of the tray 2 of FIG. 7 taken along line AA. FIG. 9 is a bottom view of the tray 2.

[0021] As shown in Figure 1, the tray 2 comprises a mounting section 11, a pair of gripping sections 12, a separator section 13, an outer foot section 14, and an inner foot section 15.

[0022] In the cabinet 1, the pair of gripping portions 12 of the first tray 2A support outer legs 14 of the second tray 2B. Also, the separator portion 13 of the first tray 2A supports inner legs 15 of the second tray 2B.

[0023] (Placement section) The mounting portion 11 has a flat plate shape. Three storage batteries 100 are arranged side by side in the left-right direction (X-axis direction in the figure) on the mounting portion 11 (see FIG. 11). More specifically, the mounting portion 11 includes a first mounting portion 110 and a second mounting portion 111 arranged side by side in the up-down direction of the mounting portion 11 (Z-axis direction in the figure) (see FIGS. 5 and 6, etc.). The first mounting portion 110 and the second mounting portion 111 have a flat plate shape. The first mounting portion 110 and the second mounting portion 111 are rectangular in plan view (see FIGS. 7 and 9, etc.). The surface of the upper side (positive direction of the Z-axis in the figure) of the first mounting portion 110 has an area large enough to mount multiple (here, three) storage batteries 100 side by side in the left-right direction (X-axis direction in the figure). The upper surface of the first mounting portion 110 is the surface on which the storage battery 100 is placed, and corresponds to the "mounting surface" in the present disclosure. Therefore, hereinafter, the upper surface of the first mounting portion 110 may be referred to as the "mounting surface."

[0024] The first mounting portion 110 and the second mounting portion 111 of the mounting portion 11 are fixed by a plurality of first fixing members 113. More specifically, ten first fixing members 113 penetrate the first mounting portion 110 and the second mounting portion 111, thereby fixing the first mounting portion 110 and the second mounting portion 111. Each of the first fixing members 113 is, for example, a fastening member.

[0025] The mounting portion 11 is provided with a hole 112. More specifically, the hole 112 is a through hole that penetrates the first mounting portion 110 and the second mounting portion 111 of the mounting portion 11. As shown in Figure 3, the hole 112 includes a first through hole 112a, a second through hole 112b, and a third through hole 112c. The first through hole 112a is provided between the first gripping portion 121 and the first separator portion 131, which will be described later. The first through hole 112a is rectangular in plan view. The second through hole 112b is provided between the first separator portion 131 and the second separator portion 132, which will be described later. The second through hole 112b is rectangular in plan view. The third through hole 112c is provided between the second separator portion 132 and the second gripping portion 122, which will be described later. The third through-hole 112c is rectangular in plan view. By providing the hole 112 in the mounting section 11, the weight of the cabinet 1 can be reduced.

[0026] (gripping part) The pair of gripping portions 12 are provided on both ends of the placement portion 11 in the left-right direction (X-axis direction in the figure) (see FIG. 3). More specifically, the pair of gripping portions 12 include a first gripping portion 121 and a second gripping portion 122.

[0027] The first gripping portion 121 is provided at the left end of the placement portion 11 in the left-right direction (the X-axis direction in the drawing). The first gripping portion 121 extends upward (in the positive direction of the Z-axis in the drawing) from the first placement portion 110. The first gripping portion 121 has a flat plate shape. The first gripping portion 121 is formed integrally with the placement portion 11 (first placement portion 110).

[0028] A first outer receiving portion 121a is formed on the upper portion of the first gripping portion 121. The first outer receiving portion 121a includes a surface parallel to the first placing portion 110 (placing surface) of the placing portion 11. In this disclosure, "parallel" includes not only strict parallelism but also substantial parallelism. Substantial parallelism includes an allowable degree of angular error (tolerance). More specifically, the first outer receiving portion 121a is formed by bending the upper portion of the flat first gripping portion 121 outward. The first outer receiving portion 121a corresponds to the "first receiving portion" in this disclosure. That is, as shown in FIG. 1, in a cabinet 1 in which a second tray 2B is stacked on a first tray 2A, the first outer receiving portion 121a of the first gripping portion 121 of the first tray 2A receives the outer foot 14 (more specifically, the first outer foot 141a) of the second tray 2B. In other words, the first gripping portion 121 of the first tray 2A is configured to be able to support the outer legs 14 of the second tray 2B.

[0029] The upper end portion 121b is formed by bending the first outer receiving portion 121a downward (in the negative Z direction in the figure). The upper end portion 121b is formed by hemming. By forming the upper end portion 121b by hemming, the strength of the upper end portion 121b can be further increased.

[0030] The first outer receiving portion 121a is provided with first protrusions 121c. More specifically, the two first protrusions 121c protrude upward (in the positive Z direction in the figure) from the surface of the first outer receiving portion 121a. The first protrusions 121c are cylindrical, but may also be polygonal or elliptical. That is, as shown in FIG. 1, in a cabinet 1 in which a second tray 2B is stacked on top of a first tray 2A, the first protrusions 121c of the first gripping portion 121 of the first tray 2A fit into the first positioning holes 141b of the first outer foot portions 141 of the second tray 2B.

[0031] The second gripping portion 122 is located at the right end of the mounting portion 11 in the left-right direction (X-axis direction in the figure). The second gripping portion 122 extends upward from the first mounting portion 110 (in the positive Z-axis direction in the figure). The second gripping portion 122 has a flat plate shape. The second gripping portion 122 is formed integrally with the mounting portion 11 (first mounting portion 110).

[0032] A second outer receiving portion 122a is formed on the upper part of the second gripping portion 122. The second outer receiving portion 122a includes a surface parallel to the first mounting portion 110 (mounting surface) of the mounting portion 11. More specifically, the second outer receiving portion 122a is formed by bending the upper part of the flat second gripping portion 122 outward. The second outer receiving portion 122a corresponds to the "first receiving portion" as referred to in this disclosure. That is, as shown in Figure 1, in a cabinet 1 in which the second tray 2B is stacked on top of the first tray 2A, the second outer receiving portion 122a of the second gripping portion 122 of the first tray 2A receives the outer feet 14 (more specifically, the second outer feet 142a) of the second tray 2B. In other words, the second gripping portion 122 of the first tray 2A is configured to support the outer feet 14 of the second tray 2B.

[0033] The upper end portion 122b is formed by bending the second outer receiving portion 122a downward (in the negative Z direction in the figure). The upper end portion 122b of the second gripping portion 122 is formed by hemming. By forming the upper end portion 122b by hemming, the strength of the upper end portion 122b can be further increased.

[0034] The second outer receiving portion 122a is provided with a second projection 122c. More specifically, two second projections 122c protrude upward (in the positive Z direction in the figure) relative to the surface of the second outer receiving portion 122a. The second projections 122c are cylindrical, but may also be polygonal or elliptical. That is, in a cabinet 1 in which the second tray 2B is stacked on top of the first tray 2A as shown in Figure 1, the second projection 122c of the second gripping portion 122 of the first tray 2A fits into the second positioning hole 142b of the second outer foot portion 142 of the second tray 2B.

[0035] (Separator section) The separator section 13 is provided between a pair of gripping sections 12 in the left-right direction (X-axis direction in the figure) of the mounting section 11. The separator section 13 is positioned between the three batteries 100 when the three batteries 100 are mounted on the mounting section 11. The separator section 13 extends upward from the mounting section 11 (in the positive Z-axis direction in the figure). The separator section 13 separates the three batteries 100 in the left-right direction (X-axis direction in the figure) of the mounting section 11.

[0036] More specifically, the separator section 13 includes a first separator section 131 and a second separator section 132. The first separator section 131 and the second separator section 132 are provided between the first gripping section 121 and the second gripping section 122 in the left-right direction (X direction in the figure) of the mounting section 11. The first separator section 131 and the second separator section 132 are adjacent to each other in the left-right direction (X direction in the figure) of the mounting section 11. The first separator section 131 and the second separator section 132 extend upward from the first mounting section 110 (in the positive Z direction in the figure). The first separator section 131 and the second separator section 132 have a flat plate shape.

[0037] The first separator section 131 and the first gripping section 121 are adjacent to each other in the left-right direction (X direction in the figure) of the mounting section 11. The main flat surface of the first separator section 131 faces the main flat surface of the first gripping section 121 in the left-right direction (X axis direction in the figure). One storage battery 100 can be mounted between the first separator section 131 and the first gripping section 121 in the first mounting section 110.

[0038] The first separator section 131 and the second separator section 132 are adjacent to each other in the left-right direction (X direction in the figure) of the mounting section 11. The main surface of the flat plate of the first separator section 131 faces the main surface of the flat plate of the second separator section 132 in the left-right direction (X axis direction in the figure). One storage battery 100 can be mounted between the first separator section 131 and the second separator section 132 in the first mounting section 110.

[0039] The second separator portion 132 and the second gripping portion 122 are adjacent to each other in the left-right direction (X direction in the figure). The main surface of the flat plate of the second separator portion 132 faces the main surface of the flat plate of the second gripping portion 122 in the left-right direction (X axis direction in the figure). In the first mounting portion 110, one storage battery 100 can be mounted between the second separator portion 132 and the second gripping portion 122.

[0040] A first inner receiving portion 131a is formed on the upper portion of the first separator portion 131. The first inner receiving portion 131a includes a surface parallel to the first mounting portion 110 (mounting surface) of the mounting portion 11. More specifically, the first inner receiving portion 131a is formed by bending the upper portion of the flat first separator portion 131 inward (in the positive direction of the X axis in the figure). The first inner receiving portion 131a corresponds to the "second receiving portion" referred to in the present disclosure. That is, as shown in FIG. 1, in the cabinet 1, the first inner receiving portion 131a of the first separator portion 131 of the first tray 2A receives the first inner foot portion 151 of the second tray 2B (more specifically, the lower end portion 151a of the first inner foot portion 151). In other words, the first separator portion 131 of the first tray 2A is configured to be able to support the first inner foot portion 151 of the second tray 2B.

[0041] A second inner receiving portion 132a is formed on the upper portion of the second separator portion 132. The second inner receiving portion 132a includes a surface parallel to the first mounting portion 110 (mounting surface) of the mounting portion 11. More specifically, the second inner receiving portion 132a is formed by bending the upper portion of the flat second separator portion 132 inward (in the negative direction of the X axis in the figure). The second inner receiving portion 132a corresponds to the "second receiving portion" referred to in the present disclosure. That is, as shown in FIG. 1, in the cabinet 1, the second inner receiving portion 132a of the second separator portion 132 of the first tray 2A receives the second inner foot portion 152 of the second tray 2B (more specifically, the lower end portion 152a of the second inner foot portion 152). In other words, the second separator portion 132 of the first tray 2A is configured to be able to support the second inner foot portion 152 of the second tray 2B.

[0042] The upper ends of the pair of gripping portions 12 and the upper end of the separator portion 13 are flush. In this disclosure, "flush" means that the surfaces of multiple components are flush with each other. "Flush" refers not only to perfect flushness but also to substantial flushness. Substantial flushness includes an allowable degree of angular error (tolerance). More specifically, the first outer receiving portion 121a of the first gripping portion 121, the second outer receiving portion 122a of the second gripping portion 122, the first inner receiving portion 131a of the first separator portion 131, and the second inner receiving portion 132a of the second separator portion 132 are flush with each other in the front-to-back direction (the Y-axis direction in the figure) and the left-to-right direction (the X-axis direction in the figure). This makes it easier to stack the second tray 2B on top of the first tray 2A, as shown in FIG. 1. This also makes it less likely for the cabinet 1 to tip over.

[0043] (lateral foot) The outer foot portion 14 is provided in the left-right direction (X-axis direction in the figure) of the mounting portion 11, at positions corresponding to each of the pair of gripping portions 12. The outer foot portion 14 corresponds to the "first foot portion" as referred to in this disclosure. More specifically, the outer foot portion 14 includes a first outer foot portion 141 and a second outer foot portion 142.

[0044] The first outer foot 141 extends downward (in the negative direction of the Z axis in the figure) from the second mounting portion 111 of the mounting unit 11 at a position corresponding to the first gripping portion 121. The second outer foot 142 extends downward (in the negative direction of the Z axis in the figure) from the second mounting portion 111 of the mounting unit 11 at a position corresponding to the second gripping portion 122. The first outer foot 141 and the second outer foot 142 have a flat plate shape. The main surface of the first outer foot 141 and the main surface of the second outer foot 142 face each other in the left-right direction (in the X-axis direction in the figure).

[0045] A first support portion 141a is formed at the lower part of the first outer foot portion 141. The first support portion 141a includes a surface parallel to the first mounting portion 110 (mounting surface) of the mounting portion 11. More specifically, the first support portion 141a is formed by bending the lower part of the flat plate-shaped first outer foot portion 141 outward (in the negative direction of the X-axis in the figure). The first support portion 141a corresponds to the "support portion" as referred to in this disclosure. That is, as shown in Figure 1, in a cabinet 1 in which the second tray 2B is stacked on top of the first tray 2A, the first outer foot portion 141a of the second tray 2B is supported by the first outer receiving portion 121a of the first gripping portion 121 of the first tray 2A.

[0046] The first support portion 141a is provided with a first positioning hole 141b. The first positioning hole 141b is a through hole. More specifically, two first positioning holes 141b penetrate the first support portion 141a in the vertical direction (Z-axis direction in the figure). The distance between the two first positioning holes 141b corresponds to the distance between the two first projections 121c. That is, as shown in Figure 1, in a cabinet 1 in which the second tray 2B is stacked on top of the first tray 2A, the first projection 121c of the first gripping portion 121 of the first tray 2A fits into the first positioning hole 141b of the first outer foot portion 141 of the second tray 2B.

[0047] A second support portion 142a is formed at the lower part of the second outer foot portion 142. The second support portion 142a includes a surface parallel to the first mounting portion 110 (mounting surface) of the mounting portion 11. More specifically, the second support portion 142a is formed by the curving of the lower part of the flat second outer foot portion 142 outward (in the positive direction of the X-axis in the figure). The second support portion 142a corresponds to the "support portion" as referred to in this disclosure. That is, as shown in Figure 1, in a cabinet 1 in which the second tray 2B is stacked on top of the first tray 2A, the second outer foot portion 142a of the second tray 2B is supported by the second outer receiving portion 122a of the second gripping portion 122 of the first tray 2A.

[0048] The second support portion 142a is provided with a second positioning hole 142b. The second positioning hole 142b is a through hole. More specifically, two second positioning holes 142b penetrate the second support portion 142a in the vertical direction (Z-axis direction in the figure). The distance between the two second positioning holes 142b corresponds to the distance between the two second projections 122c. That is, as shown in Figure 1, in a cabinet 1 in which the second tray 2B is stacked on top of the first tray 2A, the second projection 122c of the second gripping portion 122 of the first tray 2A fits into the second positioning hole 142b of the second outer foot portion 142 of the second tray 2B.

[0049] (Inner foot) The inner foot portion 15 is provided at a position corresponding to the separator portion 13 in the left-right direction of the mounting portion 11 (the X-axis direction in the figure). The inner foot portion 15 corresponds to the "second foot portion" in this disclosure. More specifically, the inner foot portion 15 includes a first inner foot portion 151 and a second inner foot portion 152.

[0050] The first inner foot portion 151 extends downward (in the negative direction of the Z-axis in the figure) from the second mounting portion 111 of the mounting portion 11 in the portion corresponding to the first separator portion 131. The first inner foot portion 151 has a flat plate shape. The lower end portion 151a of the first inner foot portion 151 is formed by hemming. By forming the lower end portion 151a by hemming, the strength of the first inner foot portion 151 can be increased. As a result, in the cabinet 1 in which the second tray 2B is stacked on top of the first tray 2A as shown in Figure 1, the first separator portion 131 of the second tray 2B can be stably supported by the first inner foot portion 151 of the first tray 2A.

[0051] Furthermore, the first inner foot portion 151 and the first separator portion 131 are fixed to the mounting portion 11 by two second fixing members 133. In this embodiment, the first inner foot portion 151 and the first separator portion 131 are separate parts, but the first inner foot portion 151 may be formed integrally with the first separator portion 131. For example, a single member that penetrates the first mounting portion 110 and the second mounting portion 111 of the mounting portion 11 may be fixed to the mounting portion 11. In this case, the upper part of the first mounting portion 110 corresponds to the first separator portion 131, and the part located below the second mounting portion 111 corresponds to the first inner foot portion 151.

[0052] The second inner foot portion 152 extends downward (in the negative Z-axis direction in the figure) from the second mounting portion 111 of the mounting portion 11 in the portion corresponding to the second separator portion 132. The second inner foot portion 152 has a flat plate shape. The lower end portion 152a of the second inner foot portion 152 is formed by hemming. By forming the lower end portion 152a by hemming, the strength of the second inner foot portion 152 can be increased. As a result, in the cabinet 1 in which the second tray 2B is stacked on top of the first tray 2A as shown in Figure 1, the second separator portion 132 of the second tray 2B can be stably supported by the second inner foot portion 152 of the first tray 2A. The main surface of the first inner foot portion 151 and the main surface of the second inner foot portion 152 face each other in the left-right direction (X-axis direction in the figure). Furthermore, the second inner foot portion 152 and the second separator portion 132 are fixed to the mounting portion 11 by two second fixing members 133. In this embodiment, the second inner foot portion 152 and the second separator portion 132 are separate parts, but the second inner foot portion 152 may be formed integrally with the second separator portion 132. For example, a single member that penetrates the first mounting portion 110 and the second mounting portion 111 of the mounting portion 11 may be fixed to the mounting portion 11. In this case, the upper part of the first mounting portion 110 corresponds to the second separator portion 132, and the part located below the second mounting portion 111 corresponds to the second inner foot portion 152.

[0053] Furthermore, the lower ends of the outer foot 14 and the inner foot 15 are flush with each other. More specifically, the first support portion 141a of the first outer foot 141, the second support portion 142a of the second outer foot 142, the lower end 151a of the first inner foot 151, and the lower end 152a of the second inner foot 152 are the same height in the front-to-back direction (Y-axis direction in the figure) and the left-to-right direction (X-axis direction in the figure). This allows the first tray 2A to be placed on flat ground, as shown in FIG. 1. This makes it difficult for the cabinet 1 to tip over.

[0054] (Flange) The tray 2 further comprises a flange portion 16. The flange portion 16 is provided at both ends of the mounting portion 11 in the front-rear direction (Y-axis direction in the figure). More specifically, the flange portion 16 includes a first flange portion 161 and a second flange portion 162.

[0055] The first flange 161 extends upward (in the positive direction of the Z axis in the figure) from the front end of the mounting portion 11 in the front-rear direction (in the Y axis direction in the figure). The first flange 161 is provided to prevent the storage battery 100 from falling from the front of the mounting portion 11 (in the positive direction of the Y axis in the figure). The first flange 161 is formed integrally with the mounting portion 11 (first mounting portion 110). An upper end portion 161a of the first flange 161 is rounded. In this embodiment, the upper end portion 161a of the first flange 161 is formed by hemming. By forming the upper end portion 161a of the first flange 161 by hemming, the strength of the mounting portion 11 can be increased.

[0056] The second flange 162 extends upward (in the positive direction of the Z axis in the figure) from the rear end of the mounting portion 11 in the front-to-rear direction (in the Y-axis direction in the figure). The second flange 162 is provided to prevent the storage battery 100 from falling from the rear of the mounting portion 11 (in the negative direction of the Y axis in the figure). The second flange 162 is formed integrally with the mounting portion 11 (first mounting portion 110). The upper end portion 162a of the second flange 162 is rounded. In this embodiment, the upper end portion 162a of the second flange 162 is formed by hemming in order to increase the strength of the mounting portion 11. By forming the upper end portion 162a of the second flange 162 by hemming, the strength of the mounting portion 11 can be increased.

[0057] In this embodiment, the upper end 161a of the first flange 161 and the upper end 162a of the second flange 162 are hemmed, which increases the strength of the mounting portion 11. Therefore, even if holes 112 are formed in the mounting portion 11 to reduce the weight of the tray 2, the mounting portion 11 does not bend, and three storage batteries 100 can be placed on it.

[0058] (2.3) Storage battery Next, the configuration of the storage battery 100, which is the subject of the cabinet 1 and the tray 2, will be described with reference to FIG. 10 . FIG. 10 is a perspective view showing the exterior of the storage battery 100. The main body 101 of the storage battery 100 is, for example, a molded product made of electrically insulating synthetic resin. The main body 101 is shaped like a rectangular parallelepiped, with a height dimension H greater than a vertical dimension D and a horizontal dimension W. A secondary battery, such as a lithium-ion battery or a nickel-metal hydride battery, is housed inside the main body 101. The storage battery 100 weighs approximately 3 kg. The main body 101 is provided with a battery terminal unit (not shown). The battery terminal unit includes, for example, at least a positive terminal connected to the positive electrode of the storage battery 100 and a negative terminal connected to the negative electrode of the storage battery 100. For example, when the storage battery 100 is connected to a charger (not shown), the output terminal of the charger and the battery terminal unit of the storage battery 100 are electrically connected, and the storage battery 100 is charged by the charger. A display unit 103 is provided on the surface of the main body 101. The display unit 103 displays the charge level of the storage battery 100. A user can visually check the remaining charge of the storage battery 100. The storage battery 100 is a portable storage battery. A handle unit 102 is provided on the main body 101.

[0059] (2.4) Using the tray Next, the use of tray 2 will be explained. Figure 11 shows the tray 2 in use. As shown in Figure 11, the user places three batteries 100 side by side in the left-right direction (X-axis direction in the figure) on the mounting section 11 of tray 2. At this time, the batteries 100 are placed on the mounting section 11 with the side with the largest surface area of ​​the rectangular parallelepiped battery 100 facing downwards. This allows the batteries 100 to be placed on the mounting section 11 in a stable state. The main body 101 of the battery 100 is provided with a handle 102, but transporting multiple batteries 100 was cumbersome. With tray 2 of this embodiment, a pair of gripping parts 12 are provided at both ends in the left-right direction (X-axis direction in the figure) on the mounting section 11, so the user can easily transport three batteries 100.

[0060] Furthermore, a separator section 13 (more specifically, the first separator section 131 and the second separator section 132 in Figure 3) is provided between the pair of gripping sections 12 in the left-right direction (X direction in the figure) of the mounting section 11. This stabilizes the three storage batteries 100 in the left-right direction (X axis direction in the figure) on the mounting section 11. This makes it easier for the user to transport the storage batteries 100.

[0061] In addition, a pair of flanges 16 (more specifically, the first flange 161 and the second flange 162 in Figure 3) are provided in the front-to-back direction of the mounting portion 11 (the Y direction in the figure), so that the three storage batteries 100 can be prevented from falling from the front-to-back direction of the mounting portion 11 (the Y axis direction in the figure).

[0062] Furthermore, a surface parallel to the first mounting portion 110 (mounting surface) of the mounting portion 11 is formed on the upper portion of each of the pair of gripping portions 12 (see the first outer receiving portion 121a and the second outer receiving portion 122a in FIG. 3 for more details). This makes it easier for the user to hold the pair of gripping portions 12 with both hands.

[0063] Furthermore, the upper end of the flange 16 is rounded, which makes it easier to smoothly remove the storage battery 100 from the tray 2. Furthermore, it also makes it easier to place the storage battery 100 on the tray 2.

[0064] As shown in FIG. 1, in a cabinet 1 in which a second tray 2B is stacked on a first tray 2A, the first protrusion 121c of the first tray 2A fits into the first positioning hole 141b provided in the first outer leg 141a of the second tray 2B (see FIG. 3). The second protrusion 122c of the first tray 2A fits into the second positioning hole 142b provided in the second outer leg 142a of the second tray 2B. This allows the user to assemble the cabinet 1 simply by placing the second tray 2B on the first tray 2A. Furthermore, the second tray 2B stacked on the first tray 2A is less likely to shift forward, backward, left, or right. This makes the cabinet 1 less likely to collapse.

[0065] The tray 2 is symmetrical in the front-to-back direction (the Y-axis direction in the figure) and in the left-to-right direction (the X-axis direction in the figure). This allows the user to stack the second tray 2B on top of the first tray 2A even when the first tray 2A is in the reversed front-to-back or left-to-right (180 degrees) orientation. This makes the cabinet 1 easier to assemble.

[0066] (2.5) Use of cabinets Next, a description will be given of the use of the cabinet 1. Fig. 12 is a diagram showing the use state of the cabinet 1. As shown in Fig. 12, the cabinet 1 of this embodiment is suitable for storing six storage batteries 100.

[0067] In the cabinet 1, the distance between the upper end of the flange 16 of the first tray 2A and the lower end of the mounting portion 11 of the second tray 2B is defined as L. In this case, as shown in FIG. 12 , the dimension L of the cabinet 1 is larger than the up-down (vertical) dimension W of the storage battery 100 mounted on the mounting portion 11. This makes it easier to remove the storage battery 100 from the cabinet 1 when removing the storage battery 100 from the mounting portion 11 of the first tray 2A of the cabinet 1 in the forward direction (positive direction of the Y axis in the figure). Furthermore, it makes it easier to store the storage battery 100 in the cabinet 1 when storing the storage battery 100 in the mounting portion 11 of the first tray 2A of the cabinet 1 in the rearward direction (negative direction of the Y axis in the figure).

[0068] Furthermore, as shown in Figure 12, when the battery 100 is placed on the mounting portion 11 of the first tray 2A, the display portion 103 of the battery 100 is visible from the front-to-back direction (Y-axis direction in the figure) between the upper end of the flange portion 16 of the first tray 2A and the lower end of the mounting portion 11 of the second tray 2B. With the cabinet 1 of this embodiment, the charge level of the battery 100 stored in the first tray 2A can be visually displayed, thus improving the usability of the cabinet 1.
