Embodiment 1 FIG.
FIG. 1 is a perspective view of an assembly box according to a first embodiment of the present invention as viewed from the opened side of a box shape. 2 is a perspective view of the assembly box shown in FIG. 1 as viewed from the closed side. The assembly box 50 has a box shape in which a wall portion 30 is erected around a bottom plate (center plate portion) 1 having a rectangular shape. The assembly box 50 is assembled into a box shape by bending a flat sheet member.

  FIG. 3 is a plan view of the sheet member before being assembled into a box shape. FIG. 4 is a partially enlarged view in which the portion A shown in FIG. 3 is enlarged. In addition, the broken line shown in FIG.3, 4 is a fold line which shows a bending location. The sheet member 40 is made of paper, for example, cardboard paper. The sheet member 40 is cut out in a shape that can be bent into a box shape.

  First, the shape of the sheet member 40 before bending will be described. The sheet member 40 includes a bottom plate 1 serving as a bottom when assembled in a box shape. In the following description, the direction along the longitudinal direction of the bottom plate 1, that is, the direction indicated by the arrow X is referred to as the first direction, and the direction along the short direction of the bottom plate 1, that is, the direction indicated by the arrow Y is the second direction. It is called direction.

  A long side plate 2 is connected to two long sides of the bottom plate 1. The long side plate 2 constitutes a part of the wall portion 30 after the sheet member 40 is bent. The long side plate 2 has a rectangular shape. The length of the long side plate 2 along the first direction is substantially the same as the long side of the bottom plate 1. Moreover, the length along the 2nd direction of the long side board 2 becomes the height of the wall part 30 at the time of making it box shape. Therefore, the length of the long side plate 2 along the second direction is determined by the height of the wall portion 30.

  On the first direction side with respect to the long side plate 2, a plate 5 is connected. The support plate 5 constitutes a part of the wall portion 30 after the sheet member 40 is bent. The plate 5 has a square shape. The length of the hook plate 5 along the first direction is substantially the same as or slightly shorter than the short side of the bottom plate 1. In addition, the length of the hook plate 5 along the second direction is substantially equal to the length of the long side plate 2 along the second direction.

  A short side plate 4 is connected to each of the two short sides of the bottom plate 1. The short side plate 4 constitutes a part of the wall portion 30 after the sheet member 40 is bent. Here, the notch 8 is formed in the side plate 5 on the side opposite to the short side plate 4. The short side plate 4 has a rectangular shape, and the length along the first direction is a length P (excluding the depth of the notch 8 from the length of the plate 5 along the second direction. Hereinafter, it is also referred to as the height of the notch 8 part). Further, the length of the short side plate 4 along the second direction is substantially equal to the short side of the bottom plate 1.

  A connecting plate 10 is connected to the side opposite to the bottom plate 1 with respect to the short side plate 4. The width Q of the connecting plate 10 is equal to or slightly larger than the width R of the notch 8. On the opposite side of the short side plate 4 with respect to the connecting plate 10, a folded plate 7 is connected. The folded plate 7 has a square shape. The folded plate 7 has a length along the second direction equal to or slightly larger than the length of the short side of the bottom plate 1.

  The length along the first direction in which the connecting plate 10 and the folded plate 7 are combined is preferably smaller than the combined length of about two sheets of the sheet member 40 and the height of the notch 8 portion. . By setting the length to such a length, it is possible to prevent the end of the folded plate 7 from being caught on the bottom plate 1 in the assembly process of the assembly box 50 described later, and the assembly to be insufficient. For example, when the length of the connecting plate 10 along the first direction is substantially equal to the thickness of about two sheets of the sheet member 40, the length of the folded plate 7 along the first direction is What is necessary is just to make it substantially equal to the length of the short side plate 4 along the 1st direction, or the height of the notch 8 part.

  Next, a procedure for folding the sheet member 40 into a box shape to form an assembly box will be described. FIGS. 5-1 to 5-8 are diagrams for explaining an assembly procedure of the assembly box 50.

  From the state before bending, as shown in FIG. 5A, the sheet member 40 is bent so that one long side plate 2 is 90 degrees with respect to the bottom plate 1. Next, as shown in FIG. 5B, the sheet member 40 is bent so that the other long side plate 2 is 90 degrees with respect to the bottom plate 1. With this bending, the posture of the plate 5 connected to the long side plate 2 also changes.

  Next, as shown in FIG. 5-3, the sheet member 40 is bent so that one of the plate members 5 is 90 degrees with respect to the long side plate 2 to which the plate plate 5 is connected. Next, as shown to FIGS. 5-4, the sheet | seat member 40 is bent so that the other platen board 5 may become 90 degree | times with respect to the long side board 2 with which the self was connected. By this bending, as shown in FIG. 5-5, the two plate plates 5 and the notches 8 overlap each other. This bending is also performed on the side opposite to the illustrated side.

  Next, as illustrated in FIG. 5-5, the sheet member 40 is bent so that the short side plate 4 is 90 degrees with respect to the bottom plate 1. With this bending, the postures of the connecting plate 10 and the folded plate 7 also change. Next, as shown in FIGS. 5-6, the sheet member 40 is folded so that the folded plate 7 is folded inside the box shape. By this bending, the connecting plate 10 is fitted into the notch 8.

  Next, as shown in FIG. 5-7, the plate member 5 is sandwiched between the short side plate 4 and the folded plate 7 by folding the sheet member 40 so that the folded plate 7 is further folded inward. By this bending, as shown in FIGS. 5-8, a box-shaped assembly box 50 in which the wall 30 is erected is formed.

  Here, since the width Q of the connecting plate 10 is equal to or slightly larger than the width R of the notch 8, the connecting plate 10 fits firmly into the notch 8 when the folded plate 7 is folded. Thereby, it can suppress that the box shape of assembly box 50 collapses.

  Further, the folded plate 7 has a length along the second direction equal to or slightly larger than the length of the short side of the bottom plate 1. The folded plate 7 fits securely. Thereby, it can suppress that the box shape of assembly box 50 collapses. Moreover, since no locking hole is formed, it is possible to suppress the generation of debris and a decrease in strength due to the formation of the locking hole.

  Next, the usage example which uses the assembly box 50 mentioned above as a protective material which protects a solar cell module is demonstrated. FIG. 6 is a diagram showing a state in which an assembly box 50 as a protective material is attached to the solar cell module. FIG. 7 is a partially enlarged cross-sectional view of the frame portion of the solar cell module to which the assembly box 50 is attached.

  As shown in FIG. 7, the solar cell module 70 includes a solar cell panel 15 that has a flat plate shape as a whole, and a frame 14 that surrounds and holds the periphery of the solar cell panel 15. The assembly box 50 is attached to both sides of the solar cell module 70 so that the side portions of the solar cell module 70 are accommodated inside the box shape.

  Here, if the length of the long side of the bottom plate 1 of the assembly box 50, that is, the length of the inner side in the longitudinal direction of the assembly box 50 is made substantially equal to the length of the frame 14 to be accommodated, the accommodated solar cell module The folded plate 7 is pressed by 70. Thereby, it can suppress that the assembly box 50 collapse | crumbles because the folding | turning board 7 will expand | deploy after attachment to the solar cell module 70. FIG.

  Returning to FIG. 4, the long side plate 2 constituting a part of the wall portion 30 is formed with a plurality of cuts 12 extending along the second direction from the side opposite to the bottom plate 1. . The portion sandwiched between the cuts 12 becomes the handle portion 13. As shown in FIG. 7, the solar cell module 70 can be held without directly touching the frame 14 by folding the handle portion 13 so as to be folded inside the frame 14.

  Further, at the portion where the handle portion 13 is bent, the height of the wall portion 30 is lowered, so that it is easy to put a finger on the inside of the frame 14. Thereby, it becomes possible to hold | maintain the solar cell module 70 more stably, and the fall during conveyance of the solar cell module 70 becomes difficult to generate | occur | produce. If the distance S from the tip of the notch 12 to the long side of the bottom plate 1 is equal to or smaller than the width T of the frame 14, the handle portion 13 can be brought into contact with the inside of the frame 14 by bending the handle portion 13. Therefore, more stable holding becomes possible.

  In the present embodiment, cuts 12 are provided in both long side plates 2. Thereby, since the handle part 13 can be bent regardless of which of the long side plates 2, it can be attached to the solar cell module 70 without worrying about the direction of the assembly box 50. Note that the cuts 12 may be provided only in one of the long side plates 2.

  As described above, the assembly box according to the present invention is useful as an assembly box for folding a plate-shaped sheet member into a box shape.
