Description

  The present invention relates to a foldable storage box that can be used as a seat chair in addition to a use as a storage box for storing articles, and can be folded into a compact shape convenient for storage when not in use.

  As this type of foldable storage box, a storage box is known which includes a box, a bottom plate placed on the bottom surface of the box, and a lid that covers the top opening of the box (for example, Patent Documents). 1 and 2). In addition to being able to be used as a box for storing articles, these storage boxes can also be used as seat chairs with a lid covering the opening of the box as a seat surface. When not in use, only the box or the box and lid can be used. It is configured so that both sides of the body can be folded compactly.

  However, the folding storage boxes disclosed in these documents have various problems. The folding storage box disclosed in the following Patent Document 1 has four extending walls whose lid extends below the four sides of the top surface, and each extending wall is foldable with respect to the top surface and is opposed to each other. The pair of extending walls has a structure that can be folded along an inclined folding line from the corner end where the three surfaces intersect. When not in use, fold the lid and box together and store them on the bottom plate. However, with such folding and overlapping, there is a concern that each part may be lost during storage. For this reason, there is a problem in storability in that an extra measure such as binding the whole with a string is required.

  Patent Document 2 below discloses a storage stool that maintains a rectangular parallelepiped shape without folding the lid. When not in use, the box is folded and stored together with the bottom plate in a rectangular parallelepiped lid. However, the scope of rights for this utility model registration is very unclear. According to the first aspect of the present invention, “the pair of side wall portions of the first to fourth side wall portions can be bent by the fifth and sixth bent portions extending in the vertical direction at the center portion in the width direction. And “-”. It is ambiguous and unclear what range the “central part” in this sentence refers to. The Utility Model Law Article 5, Paragraph 6, Item 2 stipulates that “the idea of receiving a utility model is clear” as a description requirement for the scope of a utility model registration request. In the expression “central part”, it is unclear which range is included in the “central part”, and it is difficult to think that the description requirement “the device is clear” is satisfied.

  For example, as shown in FIG. 15 (1), the bent portions 55 and 56 of the third and fourth side wall portions 53 and 54 to be bent are both positioned at the center of the third and fourth side wall portions 53 and 54. Assume that the first and second side wall portions 51 and 52 opposed to 57 and 58 are slightly shifted to the second side wall portion 52 side. This is also the “central part” because it is only a short distance away. However, when the third and fourth side wall portions 53 and 54 are bent in this state, the state becomes as shown in (2) of FIG. 15 and cannot be folded.

  Also, as shown in FIG. 16A, the width L1 of the third and fourth side wall portions 53 and 54 to be bent is twice the width L2 of the first and second side wall portions 51 and 52 facing each other. If it is wider, the bent portions 55 and 56 collide as shown in FIG. 16 (2) when the width centers of the third and fourth side wall portions 53 and 54 are bent as the bent portions 55 and 56. And cannot be folded. Even if it is forcibly folded, the first and second side walls 53 and 54 are larger than the width L2 of the first and second side walls 51 and 52 because the half dimension of the width L1 of the third and fourth side walls 53 and 54 is larger. It is impossible to sandwich the third and fourth side wall parts 53 and 54 between the two side wall parts 51 and 52 in a folded state. That is, this invention is considered to include invalid reasons because the invention includes embodiments that are not clear and cannot be implemented. Claims 2 and 3 quoting claim 1 are considered to be the same.

And when not in use, it is convenient for storage because it can be folded and stored in the compact form shown in FIG. 3 in the same manner as the folding storage box 1 of the first embodiment.

(Third embodiment)
FIG. 7 is an external view of a foldable storage box 31 according to the third embodiment, and FIG. 8 is an exploded perspective view thereof. The same or equivalent parts as those of the folding storage box 1 of the first embodiment are denoted by the same reference numerals. The foldable storage box 31 includes a box body 2 that opens upward, a bottom plate 3 that is placed on the bottom surface of the box body 2, and a lid body 4 that covers the upper opening of the box body 2. The box 2 is a box shape surrounded by the first, second, third, and fourth side walls 6, 7, 8, and 9, and the horizontal cross-sectional shape at an arbitrary height is the same. The first and second side walls 6 and 7 have the same width and face each other in parallel. The third and fourth side walls 8 and 9 are symmetrical with respect to the plane including the width center line of the first and second side walls 6 and 7, and the width center line extending in the vertical direction provided at the center of the side wall width. 10 and 11 so that it can be bent. FIG. 9 is a plan view of the box 2.

  When this foldable storage box 31 is used as a storage box, as shown in FIGS. 7 and 8, the storage is made by folding the width center lines 10 and 11 of the third and fourth side walls 8 and 9 toward the inside of the box. Used as a time shape. The bottom of the box 2 is covered with a soft cloth material having a shape that matches the shape when stored. The bottom plate 3 is formed in a shape that fits exactly at the bottom of the box 2 in the stored state, and is detachably mounted on the bottom surface of the box 2 that is in the stored shape. The lid 4 can accommodate the upper end of the box 2 that is shaped when housed inside, and the box 2 folded as described later includes the first and second side walls 6 and 7 as the lid 4. As shown in FIG. 10, it is formed in a rectangular box shape that can be stored in a state parallel to the top plate. In order for the folded box 2 to be accommodated in the lid 4 as shown in FIG. 10, the height of the first, second, third, and fourth side walls 6, 7, 8, 9 is set to the shape at the time of storage. It is necessary to keep the distance between the first and second side walls 6 and 7 of the box body 2 to be equal to or smaller than that.

  When the storage box 31 is not used, the third and fourth side walls 8 and 9 folded at the width center lines 10 and 11 are sandwiched between the first and second side walls 6 and 7 as shown in FIG. To do. FIG. 12 is a view showing a process of folding the box 2 having a storage shape into the state shown in FIG. The fourth side wall 9 is folded at the width center line 11 and folded, and is folded on the second side wall 7. Next, the third side wall 8 is folded and folded at the width center line 10 at the same time, and at the same time, the first side wall 6 is folded thereon. As a result, the box 2 is folded into a flat shape as shown in FIG.

  The dimension of 1/2 of the side wall width of the third and fourth side walls 8 and 9 is larger than 2/3 of the width of the first and second side walls 6 and 7, and the first and second side walls 6 and The value is smaller than the width of 7 by the side wall thickness. Preferably, the dimension of ½ of the side wall width of the third and fourth side walls 8 and 9 is preferably smaller than the width of the first and second side walls 6 and 7 by 1 to 3 times the side wall thickness. . In such a dimension, when the fourth side wall 9 folded at the width center line 11 is folded on the second side wall 7, it is between the width center line 11 part and the inside of the first side wall 6. Leaves a slight gap of 1-2 times the side wall thickness. Since the half of the side wall width of the third and fourth side walls 8 and 9 is larger than 2/3 of the width of the first and second side walls 6 and 7, the box 2 is folded flat. Further, the bending corner along the width center line 10 of the third side wall 8 and the bending corner along the width center line 11 of the fourth side wall 9 do not overlap.

  In the state where the width center line 10 part of the third side wall 8 is also folded, it becomes the same as the width center line 11 part of the fourth side wall 9. Since the connecting portion between the second side wall 7 and the third side wall 8 is folded with the folded fourth side wall 9 sandwiched therebetween, the folded corner is slightly rounded. The side wall is formed by covering the plate material with the cloth material, and the corner portion has the structure in which the cloth material is connected, so that the fourth side wall 9 folded by the slight expansion and contraction and deformation of the cloth material is sandwiched therebetween. Folding is possible.

  The box body 2 is folded in this way, and is stacked on the removed bottom plate 3 and stored in the lid body 4 as shown in FIG. The heights of the first, second, third, and fourth side walls 6, 7, 8, and 9 are set such that the box 2 that is folded into a flat shape fits in the lid 4 as described above. That is, the height is allowed to be approximately equal to the dimension between the first and second side walls 6 and 7 in the storage shape. Further, the height of the side wall of the lid 4 is adjusted to a height at which the stored item is just stored in the lid 4 in a state where the folded box 2 and the bottom plate 3 are accommodated.

  The foldable storage box 31 having such a structure can be used as a storage box for storing articles in a state of being stored, and a seat chair with a lid 4 placed on the box 2 as a seat surface. Can also be used. And when not in use, it can be folded and stored in a compact form as shown in FIG. In addition, when the folding storage box 31 of the present embodiment is in the shape of storage, the third and fourth side walls 8 and 9 are bent with the width center lines 10 and 11 approaching the inside of the box. For this reason, the lid 4 serving as a seating surface is reliably supported by the bent portion, and has an advantage that the force to withstand the load from above is increased because the portion is closer to the inside of the box. Further, in the state of being stored, a wide storage box in which the dimension between the first and second side walls 6 and 7 is about twice the side wall width of the first and second side walls 6 and 7 can be manufactured. . In addition, the height of the first, second, third, and fourth side walls 6, 7, 8, and 9 is approximately equal to the dimension between the first and second side walls 6 and 7 in the storage shape. Since it is allowed, it has an advantage that a storage box having a high height and a seat chair having a high height can be manufactured.

(Fourth embodiment)
FIG. 13 is an external view of a foldable storage box 41 according to the fourth embodiment, and FIG. 14 is an exploded perspective view thereof. The same or equivalent parts as those of the folding storage box 1 of the first embodiment are denoted by the same reference numerals. The foldable storage box 41 includes a box body 2 that is open at the top, a bottom plate 3 that is placed on the bottom surface of the box body 2, and a lid body 4 that covers the upper opening of the box body 2. This foldable storage box 41 is different from the foldable storage box 31 of the third embodiment in that the third and fourth side walls 8 and 9 are centered in the width when the storage box 41 is used as a storage box. It is to be used in a straight line state without being bent at the lines 10 and 11. The width of the third and fourth side walls 8 and 9 in the straight state is the same as that of the folding storage box 31 of the third embodiment. The value is larger than 2/3 of the side walls 6 and 7 and smaller than the width of the first and second side walls 6 and 7 by the thickness of the side walls.

  The foldable storage box 41 having such a configuration also has the same advantages as the foldable storage box 31 of the third embodiment. A slight difference is that the width centerlines 10 and 11 of the third and fourth side walls 8 and 9 are not moved to the inner side of the box when the storage body is in the storage shape, so that the box body 2 has the first, second and third The fourth side wall 6, 7, 8, 9 is supported only by the upper end surface.

  In the drawings, 1, 21, 31, and 41 are folding storage boxes, 2 is a box, 3 is a bottom plate, 4 is a lid, 6 is a first side wall, 7 is a second side wall, and 8 is a third side wall. , 9 are fourth side walls, and 10, 11 are width center lines.
