[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-015090 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned prior art document, batteries with the same width are stored in the battery storage device. However, if the battery storage boxes to be stored are reused products that have been used for various other purposes, it becomes necessary to store battery storage boxes with different widths in the battery storage device.

[0005] In this case, it becomes necessary to prepare a dedicated storage box or attachment according to the width dimension of the storage battery (heavy object), which increases the number of parts. As a result, in the prior art, the storage (accommodation) work becomes complicated, it becomes difficult to standardize parts, and there is a possibility that this will lead to high costs.

[0006] SUMMARY OF THE INVENTION In consideration of the above, an object of the present invention is to provide a heavy object storage device capable of storing heavy objects of different width dimensions. [Means for solving the problem]

[0007] The heavy object storage device of the invention described in claim 1 is composed of a frame member that stores multiple heavy objects in multiple levels in the vertical direction and has entrances and exits for the heavy objects to be taken in and out along an approximately horizontal direction, and is equipped with a plurality of pillar members extending along the height direction of the frame member, and a pair of attachments that extend approximately horizontally relative to the multiple pillar members arranged in the depth direction of the frame member and support each of the widthwise ends of the heavy objects that are approximately perpendicular to the direction in which the heavy objects are taken in and out, and the attachments have different lengthwise dimensions along two directions approximately perpendicular to the extension direction, and are composed of a long side portion that is formed so that the lengthwise dimension is relatively long, and a short side portion that is formed so that the lengthwise dimension is shorter than the long side portion, and the long side portion and the short side portion are capable of being fixed to the pillar members and the heavy objects, respectively.

[0008] The heavy object storage device according to the invention of claim 1 is comprised of a frame member that stores multiple heavy objects in multiple stages in the height direction, and the frame member is provided with an entrance / exit for the heavy objects along a substantially horizontal direction. Pillar members extend along the height direction of the frame member. Furthermore, a pair of attachments extend along a substantially horizontal direction to the multiple pillar members arranged in the depth direction of the frame member, and the pair of attachments support both widthwise ends of the heavy objects.

[0009] Here, the attachment is configured to include long and short side portions whose longitudinal dimensions along two directions substantially perpendicular to the extension direction are different from each other. The long side portions are formed to have a relatively long longitudinal dimension, and the short side portions are formed to have a shorter longitudinal dimension than the long side portions. The long and short side portions can be fixed to a pole member and a heavy object, respectively.

[0010] For example, when the long side of the attachment is fixed to the pillar member, the short side of the attachment is fixed to the heavy object, and when the short side of the attachment is fixed to the pillar member, the long side of the attachment is fixed to the heavy object.

[0011] The long side and short side have different longitudinal dimensions, so for example, when the width dimension of the heavy object is small, the heavy object is supported by the long side of the attachment, and when the width dimension of the heavy object is large, the heavy object is supported by the short side of the attachment.

[0012] In this way, in the present invention, by using attachments with different longitudinal dimensions of the support part (long side part or short side part) that supports the heavy object, it is possible to support heavy objects with different width dimensions with a single type of attachment.

[0013] That is, in the present invention, the widthwise distance between a pair of attachments can be changed, and multiple heavy objects with different width dimensions (sizes) can be accommodated in the same heavy object accommodation device using the same attachments.

[0014] The heavy object storage device of the invention described in claim 2 is a heavy object storage device of the invention described in claim 1, in which the long side portions and the short side portions are provided with hole portions that enable the long side portions and the short side portions to be fixed to the column members or the heavy object, respectively, via fasteners.

[0015] In the heavy object storage device according to the invention of claim 2, holes are provided on the long and short sides of the attachment, respectively, which allow the long and short sides to be fixed to the pillar members or the heavy object via fasteners.

[0016] The heavy object storage device of the invention described in claim 3 is a heavy object storage device of the invention described in claim 2, wherein the hole portion of at least one of the long side portion and the short side portion is a long hole formed along the longitudinal direction.

[0017] In the heavy object storage device according to the invention of claim 3, the hole portion of at least one of the long side portion and the short side portion is an elongated hole formed along the length direction of the long side portion and the short side portion. For example, by making the hole portion for fixing the heavy object an elongated hole, the position of the fixing portion for fixing via a fastener can be changed.

[0018] Therefore, in the present invention, it is possible to adjust the position of the fixing part in accordance with the width dimension of the heavy object, and it is possible to further increase the variety of width dimensions of heavy objects that can be accommodated.

[0019] The heavy object storage device of the invention described in claim 4 is a heavy object storage device of the invention described in claim 2, in which the hole portions of at least one of the long side portion and the short side portion are circular holes formed in multiple positions along the longitudinal direction.

[0020] In the heavy object storage device according to the invention of claim 4, the hole portions of at least one of the long side portion and the short side portion are circular holes formed in a plurality of positions along the length of the long side portion and the short side portion. For example, by forming the hole portions for fixing the heavy object into a plurality of circular holes, the position of the fixing portion for fixing the heavy object via a fastener can be changed.

[0021] Therefore, in the present invention, it is possible to adjust the position of the fixing part to match the width dimension of the heavy object, and when the variation in the width dimension of the heavy object is limited, it is possible to fix the long and short sides of the heavy object more firmly by fixing the fastener to the heavy object using the round hole.

[0022] A heavy object accommodation device according to a fifth aspect of the invention is the heavy object accommodation device according to the first aspect of the invention, wherein the attachment has a substantially L-shaped shape when viewed from the extending direction.

[0023] In the heavy object storage device according to the invention described in claim 5, the attachment has an approximately L-shaped shape when viewed from the extension direction, and is configured to include a long side portion and a short side portion whose dimensions in the length direction approximately perpendicular to the extension direction are different from each other.

[0024] The heavy object storage device of the invention described in claim 6 is a heavy object storage device of the invention described in claim 1, which is provided with a plurality of first fixing holes formed along the height direction of the pillar member, which enable the long side portion or the short side portion to be fixed to the pillar member via fasteners.

[0025] In the heavy object storage device according to the invention of claim 6, a plurality of first fixing holes are formed along the height direction of the pole member, and the long side or short side of the attachment can be fixed to the pole member via a fastener. In this way, by fixing a plurality of attachments along the height direction of the pole member, the heavy object storage device can store a plurality of heavy objects in multiple stages in the height direction, and can also store heavy objects of different heights.

[0026] The heavy object storage device of the invention described in claim 7 is a heavy object storage device of the invention described in claim 1, in which a flange portion that protrudes outward in the width direction of the heavy object is formed on at least one of both ends of the width direction of the heavy object, and the long side portion or the short side portion is abutted against the underside of the flange portion and can be fixed.

[0027] In the heavy object storage device according to the invention of claim 7, the heavy object is provided with a flange portion on at least one of both ends in the width direction of the heavy object. The flange portion is formed to protrude outward in the width direction of the heavy object. The long side or short side of the attachment can be abutted against the underside of the flange portion and fixed.

[0028] For example, if the heavy object is a vehicle-mounted storage battery, a flange may be formed on the outer side of the battery in the width direction, and the storage battery may be fastened to the locker via the flange. In this case, the flange has a fastening hole formed therein. The flange can be fastened to the attachment using the fastening hole.

[0029] The heavy object storage device of the invention described in claim 8 is a heavy object storage device of the invention described in claim 7, in which the long side portions and the short side portions are provided with hole portions that enable the long side portions and the short side portions to be fixed to the column member or the heavy object, respectively, via fasteners, and the flange portion is formed with a plurality of second fixing holes along the direction in which the heavy object moves in and out, and the hole portions are formed in plurality along the extension direction of the attachment in correspondence with the second fixing holes.

[0030] In the heavy object storage device of the invention described in claim 8, a plurality of second fixing holes are formed in the flange portion along the direction in which the heavy object is inserted and removed, and a plurality of holes are formed in the long side portion and the short side portion along the extension direction of the attachment in correspondence with the second fixing holes.

[0031] By matching the second fixing hole formed in the flange portion of the heavy object with the hole formed in the long side or short side portion of the attachment, it is possible to fix the heavy object to the attachment via a fastener.

[0032] A heavy object accommodation device according to the invention recited in claim 9 is the heavy object accommodation device according to the invention recited in claim 1, wherein the heavy object is a storage battery.

[0033] In a heavy object accommodation device according to the invention of claim 9, the heavy object is a storage battery, and the storage battery is accommodated within the heavy object accommodation device. Since the present invention can accommodate storage batteries of different width dimensions, it is possible to accommodate, for example, a reused storage battery that has been used for purposes other than vehicle storage batteries in the same heavy object accommodation device. [Effects of the Invention]

[0034] As described above, the heavy object storage device according to the present invention can store heavy objects with different width dimensions. [Brief explanation of the drawings]

[Figure 3B] FIG. 3B is a cross-sectional view taken along the line AA shown in FIG. 3A. [Figure 4] 1 is a schematic perspective view showing a battery pack accommodated in a battery pack accommodation device according to the present embodiment; DETAILED DESCRIPTION OF THE INVENTION

[0036] Hereinafter, a heavy object accommodation device according to an embodiment of the present invention will be described with reference to the drawings. (Configuration of heavy object storage device) First, the configuration of a heavy object accommodation device according to an embodiment of the present invention will be described.

[0037] 1 shows a battery pack accommodation device 10 as a heavy object accommodation device according to this embodiment. The battery pack accommodation device 10 is made up of a frame member 12 and has a rectangular box shape. For example, in this embodiment, the battery pack accommodation device 10 includes a front frame portion 14 and a rear frame portion 16, with the front frame portion 14 constituting the front end portion of the battery pack accommodation device 10 and the rear frame portion 16 constituting the rear end portion of the battery pack accommodation device 10.

[0038] The front frame portion 14 is configured to include a pair of pillar members 18 arranged along the height direction of the battery pack receiving device 10 (front frame portion 14). The lower ends of the pair of pillar members 18 are bridged together by a lower beam member 22, and the upper ends of the pair of pillar members 18 are bridged together by an upper beam member 24. In other words, the front frame portion 14 is configured to include the pair of pillar members 18, the lower beam member 22, and the upper beam member 24.

[0039] The rear frame portion 16 is configured to include a pair of pillar members 20 along the height direction of the battery pack receiving device 10 (rear frame portion 16). The lower ends of the pair of pillar members 20 are bridged together by a lower beam member 26, and the upper ends of the pair of pillar members 20 are bridged together by an upper beam member 28. In other words, the rear frame portion 16 is configured to include the pair of pillar members 20, the lower beam member 26, and the upper beam member 28. Although these beam members are illustrated as rectangular parallelepipeds, channel steel, H-shaped steel, etc. may be used, for example.

[0040] Furthermore, the lower ends of the pair of pillar members 18 that make up the front frame portion 14 and the lower ends of the pair of pillar members 20 that make up the rear frame portion 16 are respectively bridged by a pair of lower beam members 30. Furthermore, the upper ends of the pair of pillar members 18 that make up the front frame portion 14 and the upper ends of the pair of pillar members 20 that make up the rear frame portion 16 are respectively bridged by a pair of upper beam members 32.

[0041] The lower frame portion 34 is formed by the lower beam member 22 of the front frame portion 14, the lower beam member 26 of the rear frame portion 16, and a pair of lower beam members 30, and the upper frame portion 36 is formed by the upper beam member 24 of the front frame portion 14, the upper beam member 28 of the rear frame portion 16, and a pair of upper beam members 32. In addition, the pillar member 18 of the front frame portion 14, the pillar member 20 of the rear frame portion 16, the lower beam member 30, and the upper beam member 32 form a pair of side frame portions 38, 40.

[0042] In this way, a battery pack (storage battery) 11 can be housed within the frame member 12 formed by the front frame portion 14, rear frame portion 16, lower frame portion 34, upper frame portion 36, and a pair of side frame portions 38, 40. The opening 15 in the front frame portion 14 serves as an entrance / exit through which the battery pack 11 can enter and exit. For this reason, in the following description, this opening will be referred to as the entrance / exit 15.

[0043] The lower frame portion 34 also constitutes the base of the battery pack accommodating device 10, and for example, a pair of legs 42 hang down from the underside of the lower frame portion 34, extending from both widthwise ends of the battery pack accommodating device 10 and in the front-to-rear direction of the battery pack accommodating device 10. Although the legs 42 are illustrated as rectangular parallelepipeds, they may be made of steel such as H-beams and may be fixed to the mounting surface 44. A plurality of beam members 46 are provided within the lower frame portion 34, and are capable of coming into contact with the mounting surface 44 and bridging the pair of lower beam members 30.

[0044] Meanwhile, a plurality of beam members 48 are provided within the upper frame portion 36, spanning the pair of upper beam members 32. A plurality of column members 50 are provided within each of the pair of side frame portions 38, 40, spanning the upper beam member 32 and the lower beam member 30. The column members 50 are provided with a plurality of fixing holes (first fixing holes) 52 along the height direction, and fasteners 54 such as bolts can be fixed through the fixing holes 52.

[0045] In this embodiment, an attachment 56 is bridged (extended) between the pillar members 18, 20 in a substantially horizontal direction, and the battery pack 11 is supported by the attachment 56.

[0046] As shown in FIGS. 3A and 3B, the attachment 56 is made of, for example, a steel plate and is formed in a generally L-shape, and is set to a length that allows it to extend along the depth direction of the battery pack receiving device 10.

[0047] The attachment 56 includes a long side portion 58 and a short side portion 60, whose lengthwise dimensions L1, L2 (L1>L2) are different from each other along two directions substantially perpendicular to the extension direction. The long side portion 58 and the short side portion 60 can be fixed to the pillar members 18, 20 and the battery pack 11, respectively.

[0048] A long hole 58A is formed in the long side portion 58 along the length direction, and the long side portion 58 is fixed to the pillar members 18, 20 (or the battery pack 11) via a fastener 54 (see Figure 1) inserted into the long hole 58A.

[0049] On the other hand, round holes 60A are formed in the short side portions 60, and the short side portions 60 are fixed to the battery pack 11 (or the pillar members 18, 20) via fasteners 54 (see FIG. 1) inserted into the round holes 60A. The long holes 58A and the round holes 60A are provided on the same line along the width direction of the attachment 56, and a plurality of the long holes 58A and the round holes 60A are provided along the extension direction of the attachment 56 (described later).

[0050] 4, the battery pack 11 has a generally rectangular plate shape in a plan view, with flanges 13 projecting outward from both widthwise ends. Therefore, the battery pack 11 has generally L-shaped cutouts at the bottom and top ends of both widthwise ends when viewed from the front. In other words, a step is provided on the bottom surface of the battery pack 11.

[0051] Although not shown, the flange 13 is used to attach the vehicle to a pair of rockers extending along the front-rear direction of the vehicle at both widthwise ends of the floor panel of the vehicle. For this reason, the flange 13 is formed with a plurality of fixing holes (second fixing holes) 13A for attachment.

[0052] As mentioned above, the attachment 56 has multiple long holes 58A and round holes 60A arranged along the extension direction of the attachment 56, and are formed to match the pitch of the fixing holes 13A formed in the flange portion 13.

[0053] Therefore, when the lower surface 13B of the flange portion 13 of the battery pack 11 abuts against the attachment 56, the fixing hole 13A of the flange portion 13 and the elongated hole 58A or the round hole 60A of the attachment 56 are positioned substantially in line, allowing the fastener 62 (see FIG. 2) to be inserted. The battery pack 11 is fixed to the attachment 56 via this fastener 62. Note that the battery pack 11 is not necessarily limited to being mounted on a vehicle. Also, FIG. 2 shows a simplified shape of the battery pack 11.

[0054] (Action and effect of heavy object storage device) Next, the operation and effects of the heavy object accommodation device according to the embodiment of the present invention will be described.

[0055] In this embodiment, as shown in Figures 1 and 2, the battery pack storage device 10 is composed of a frame member 12 that stores multiple battery packs 11 in multiple stages in the vertical direction, and the frame member 12 is provided with an entrance / exit 15 that allows the battery packs 11 to enter and exit along a substantially horizontal direction.

[0056] The frame member 12 is provided with pillar members 18, 20 that extend along the height direction of the frame member 12. In addition, a pair of attachments 56 extends along the substantially horizontal direction relative to the plurality of pillar members 18, 20 that are arranged in the depth direction of the frame member 12, and the pair of attachments 56 support both ends of the battery pack 11 in the width direction.

[0057] As shown in Figures 3A and 3B, the attachment 56 is configured to include long side portions 58 and short side portions 60 that have different lengthwise dimensions along two directions that are approximately perpendicular to the extension direction and are formed approximately perpendicular to each other, and the long side portions 58 and short side portions 60 can be fixed to the pillar members 18, 20 and the battery pack 11, respectively.

[0058] 1 and 2, when the long side portions 58 of the attachment 56 are fixed to the pillar members 18 and 20, the short side portions 60 of the attachment 56 are fixed to the battery pack 11A. Also, when the short side portions 60 of the attachment 56 are fixed to the pillar members 18 and 20, the long side portions 58 of the attachment 56 are fixed to the battery packs 11B and 11B, respectively.

[0059] Furthermore, the short side 60 of the attachment 56 may be fixed to the side frame portion 38 on the side facing the pillar members 18 and 20, and the long side 58 of the attachment 56 may be fixed to the side frame portion 40 on the side facing the pillar members 18 and 20. In this case, the long side 58 of the attachment 56 on the side facing the pillar members 18 and 20 of the side frame portion 38 and the long side 58 of the attachment 56 on the side facing the pillar members 18 and 20 of the side frame portion 40 are each fixed to the battery pack 11D.

[0060] In this embodiment, the long side 58 and the short side 60 of the attachment 56 have different longitudinal dimensions. Therefore, for example, when the width of the battery pack 11B is small, the long side 58 of the attachment 56 supports the battery pack 11B, and when the width of the battery pack 11A is large, the short side 60 of the attachment 56 supports the battery pack 11A.

[0061] In this manner, in this embodiment, by using attachments 56 having different longitudinal dimensions for the support portion (long side portion 58 or short side portion 60) that supports the battery pack 11, it is possible to support battery packs 11A, 11B, etc. having different width dimensions with a single type of attachment 56.

[0062] That is, in this embodiment, it is possible to change the widthwise distance between a pair of attachments 56, and it is possible to accommodate a plurality of battery packs 11A, 11B, etc., with different width dimensions (sizes) in the same battery pack accommodating device 10 using the same attachment 56. In other words, in this embodiment, it is not necessary to prepare a dedicated battery pack accommodating device 10 for each size of battery pack 11.

[0063] In this embodiment, the attachment 56 includes a long side portion 58 and a short side portion 60, and a long hole 58A is formed along the length of the long side portion 58. The long hole 58A allows the long side portion 58 to be fixed to the pillar members 18, 20 or the battery pack 11 via fasteners 54, 62.

[0064] In this manner, in this embodiment, by forming the long hole 58A in the long side portion 58, it becomes possible to adjust the fixing position of the battery packs 11B and 11C according to the width dimension, as in the case of the battery packs 11B and 11C. Therefore, in this embodiment, it becomes possible to further increase the variation in width dimension of the battery packs 11A, 11B, 11C, and 11D that can be accommodated in the battery pack accommodation device 10.

[0065] In addition, in this embodiment, a round hole 60A is formed in the short side portion 60, and by using this round hole 60A to fix the short side portion 60 to the pillar members 18, 20 or the battery pack 11A via fasteners 54, 62, it is possible to more firmly fix the short side portion 60 to the pillar members 18, 20 or the battery pack 11A.

[0066] Furthermore, in this embodiment, the pillar member 50 has multiple fixing holes 52 along the height direction, allowing the long side portion 58 or short side portion 60 of the attachment 56 to be fixed to the pillar member 50 via fasteners 54.

[0067] In this manner, in this embodiment, by fixing a plurality of attachments 56 along the height direction of the pillar member 50, the battery pack storage device 10 is capable of storing a plurality of battery packs 11 in multiple tiers in the height direction, and is also capable of storing heavy objects of different heights.

[0068] Furthermore, in this embodiment, the battery pack 11 is formed with a pair of flange portions 13 that protrude outward from both ends in the width direction of the battery pack 11. The long side portion 58 or the short side portion 60 of the attachment 56 can be abutted against the lower surface 13B of the flange portions 13 and fixed thereto.

[0069] In the vehicle-mounted battery pack 11, a flange portion 13 is formed on the outer side of the battery pack 11 in the width direction, and the battery pack 11 is fastened to a locker (not shown) via the flange portion 13. For this reason, a fastening hole 13A is formed in the flange portion 13, and in this embodiment, the flange portion 13 can be fixed to an attachment 56 by using the fastening hole 13A.

[0070] In addition, in this embodiment, multiple fixing holes 13A are formed in the flange portion 13 along the insertion / removal direction of the battery pack 11, and multiple long holes 58A and round holes 60A are formed along the extension direction of the attachment 56 in correspondence with the fixing holes 13A.

[0071] In this embodiment, the fixing hole 13A formed in the flange portion 13 of the battery pack 11 corresponds to the long hole 58A formed in the long side portion 58 of the attachment 56 or the round hole 60A formed in the short side portion 60, making it possible to fix the battery pack 11 to the attachment 56 via the fastener 54.

[0072] Furthermore, in this embodiment, the battery pack 11 is a storage battery, and a plurality of storage batteries are housed in the battery pack housing device 10. In this embodiment, storage batteries with different width dimensions can be housed, so that, for example, a reused storage battery that has been used for purposes other than a vehicle storage battery can also be housed in the battery pack housing device 10.

[0073] <Supplementary explanation of the above embodiment>

[0074] In the above embodiment, as shown in FIG. 2, a battery pack storage device 10 that stores a battery pack 11 has been described as a heavy object storage device. However, the heavy object is not limited to a battery pack, and any storage device that stores a heavy object may be used.

[0075] In addition, in the above embodiment, as shown in FIG. 1, an entrance / exit 15 is provided on the front frame portion 14 side of the battery pack storage device 10, and the battery pack 11 can be taken in and out through the entrance / exit 15, but the battery pack 11 may also be taken in and out through the rear frame portion 16.

[0076] Furthermore, in the above embodiment, the battery pack storage device 10 is composed of a frame member 12 including a front frame portion 14, a rear frame portion 16, a lower frame portion 34, an upper frame portion 36, and a pair of side frame portions 38, 40, and each frame portion is in communication with the outside, but it goes without saying that some frame portions may be provided with walls that separate them from the outside.

[0077] 1 and 2, the attachment 56 is formed in a substantially L-shape and is composed of a long side portion 58 and a short side portion 60, but this is not limited to this. For example, although not shown, ribs may be provided on the inner surface of the attachment 56 to reinforce the long side portion 58 and the short side portion 60.

[0078] Furthermore, in the above embodiment, the long side portion 58 of the attachment 56 has the long hole 58A formed along the length thereof, but a plurality of round holes may be formed along the length of the long side portion 58. This is preferable from the viewpoint of the rigidity of the long side portion 58 when the variation in the width dimension of the battery pack 11 is limited to a certain extent.

[0079] Furthermore, in the above embodiment, a round hole 60A is formed in the short side portion 60 of the attachment 56, but a long hole may be formed along the length of the short side portion 60, or multiple round holes may be formed along the length of the short side portion 60.

[0080] In the above embodiment, the flange portions 13 protrude from both ends of the battery pack 11 in the width direction, and the flange portions 13 are fixed to the attachments 56, but the present invention is not limited to this.

[0081] For example, the flange portion 13 may be shaped to protrude from only one end side in the width direction of the battery pack 11. Furthermore, some battery packs 11 (e.g., battery packs 11B and 11D) may not have the flange portion 13. In particular, when the flange portion 13 is not formed, such as in a stationary storage battery, the end portion in the width direction of the battery pack 11 is fixed to the attachment 56.
