Description

[Technical field]

[0001] The present invention relates to an enclosure, and in particular to an enclosure that is collapsible when not in use and self-supporting to form a prismatic enclosure when in use. [Background technology]

[0002] Containers are used to temporarily store items in temporary storage areas or garbage collection areas. It is desirable for such containers to be able to store items in a relatively compact state and to be able to store items in a small size when there are no items to store.

[0003] The inventor invented a foldable container that can stand on its own when in use and can be folded and stored when not in use, and discloses it in Patent Document 1. The foldable container 1 of Patent Document 1 has a rectangular bottom portion, two opposing first side portions, and two opposing second side portions, and forms a box-shaped container body when it stands on its own. A pair of plate-shaped reinforcing members 34 extending along each of the left and right edges is provided on the two first side portions. On the other hand, such plate-shaped reinforcing members are not provided on the two second side portions. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2010-137865 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0005] The collapsible container of Patent Document 1 has a rectangular bottom surface, which makes it easy to maintain the box shape during use. However, the bottom surface may not be folded properly when folded, resulting in a bulky bottom. In addition, if the bottom surface becomes dirty with stored garbage or the like, cleaning may be required before storage.

[0006] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide an enclosure member which can store items in a self-supporting state even when an external force is applied, despite not having a bottom surface, and which can be folded up to be compact when not in use. [Means for solving the problem]

[0007] The invention of claim 1 relates to an enclosure. The enclosure of the present invention comprises a side portion having a first side portion consisting of two opposing surfaces and a second side portion consisting of two opposing surfaces, and a connecting portion connecting adjacent ends of the first side portion and the second side portion, and can form a prismatic enclosure with open upper and lower portions when in use, and can be folded when not in use. The enclosure of the present invention is characterized in that the side portion is formed of a rectangular material in a mesh or sheet shape, plate-shaped reinforcing members are disposed at both the left and right ends of the side portion, extending parallel to the ends, and rod-shaped reinforcing members are disposed in a bag at both the upper and lower ends of the side portion, and the rod-shaped reinforcing members and the plate-shaped reinforcing members are separated by the connecting portion and the bag so as not to come into contact with each other.

[0008] The plate-shaped reinforcing material of the enclosure member described in claim 2 is characterized in that it comprises a plastic plate-shaped portion having two long flat plates arranged at a predetermined distance and a plurality of partitions connecting the two long flat plates, and an auxiliary rod inserted into the hollow interior formed between the two long flat plates and the partitions.

[0009] The enclosing member according to claim 3 is characterized in that it includes a string portion that connects a lower end of the first side surface portion to a lower end of the second side surface portion, thereby stabilizing the shape of the enclosing member in a self-supporting state during use.

[0010] The enclosing member according to claim 4 is characterized in that it further comprises an attachment / detachment auxiliary part for detachably attaching the enclosing member to an external structure. Effect of the Invention

[0011] The enclosure of the present invention can be made to stand on its own with sufficient rigidity by providing plate-shaped reinforcing members at both the left and right ends of the side surface, which members extend parallel to these ends. Furthermore, the enclosure of the present invention has a stable shape due to the provision of rod-shaped reinforcing members at both the top and bottom ends of the side surface.

[0012] In the enclosing member of the present invention, the plate-shaped reinforcing member is composed of a plastic plate-shaped portion and an auxiliary rod inserted into the hollow interior of the plate-shaped portion, so that the plate-shaped reinforcing member is made of a plurality of materials with different strengths and elastic moduli. As a result, the enclosing member of the present invention has sufficient strength to withstand unexpected external forces, such as when an object is thrown in from above, and has excellent durability.

[0013] The enclosure of the present invention has a string part connecting the lower end of the first side part and the lower end of the second side part, so that the enclosure can stabilize its shape in a free-standing state when in use without providing a planar member that serves as the bottom surface. Also, the string part is easier to put away when not in use than a normal bottom surface part.

[0014] The enclosure member of the present invention can be attached to, for example, an external building or a support by means of an auxiliary attachment / detachment part for detachably attaching the enclosure member to an external structure. By fixing the enclosure member to another structure, it is possible to more reliably prevent the enclosure member from collapsing or moving due to an external force. Considering that the enclosure member is fixed to another structure, the strength of the enclosure member alone only needs to satisfy the necessary conditions, and the enclosure member can be made lighter than before.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the enclosure member of the present invention will be described with reference to the drawings. The enclosure member 1 described in this embodiment shows a form in which all four side portions are square, but this shape is not intended to limit the scope of the claims, and in fact, side portions with different dimensions in the height direction and width direction, or side portions with different dimensions between the first side portion and the second side portion, can be applied. In addition, in this embodiment, a form in which each side portion is formed from a single (single) member is described, but it is also possible to form one side by joining the ends of multiple members with a joining portion.

[0017] Fig. 1 shows a perspective view of an enclosing member 1 that is freestanding with each side portion at a right angle to the adjacent side portion. For ease of explanation, the four corner angles of the upper end portion that are created when the enclosing member 1 is freestanding are labeled a, b, c, and d below. Similarly, the four corner angles of the lower end portion that are created when the enclosing member 1 is freestanding are labeled e, f, g, and h below. Fig. 2 shows a partially enlarged perspective view of the enclosing member 1 in Fig. 1, with the vicinity of corner angles c and g broken away.

[0018] In the following description, the term "edge line" refers to the contour line of an enclosing member defined by connecting two adjacent ridge angles in the horizontal or vertical direction. In addition, the contour line of an enclosing member defined by connecting two adjacent ridge angles in the vertical direction is also called a "side edge."

[0019] As shown in FIG. 1, the enclosing member 1 of this embodiment has two substantially square first side portions 2 facing each other and two second side portions 3 facing each other. Hereinafter, the first side portion 2 and the second side portion 3 may be collectively referred to as side portions 2, 3. The side portions 2, 3 may be formed of a flexible net-like (i.e., net-like or mesh-like) material. It is also possible to replace a part or all of the side portions 2, 3 with a sheet-like material. For the side portions 2, 3, an ester tarpaulin made of polyester coated with polyvinyl chloride is preferably used.

[0020] The left and right ends of the first side portion 2 are connected via connecting portions 4 either in contact with the ends of the adjacent second side portion 3, or with the ends spaced a short distance apart across the sides.

[0021] The connecting portion 4 will be described. A polyethylene sheet is preferably used for the connecting portion 4. The connecting portion 4 is composed of two sheets, an outer surface connecting sheet 41 and an inner surface connecting sheet 42. The outer surface connecting sheet 41 and the inner surface connecting sheet 42 are formed of a foldable material and are sheets having a length that can continuously cover one side of the side portions 2 and 3. The outer surface connecting sheet 41 is arranged in contact with the outer surfaces of the side portions 2 and 3. The inner surface connecting sheet 42 includes an inner surface connecting sheet 42 arranged in contact with the inner surfaces of the side portions 2 and 3. The adjacent ends of the first side portion 2 and the second side portion 3 are connected to both the outer surface connecting sheet 41 and the inner surface connecting sheet 42 at different positions. The easiest and most reliable method of connection is sewing with thread. When sewing is performed, a sewing line S1 is formed at each connection position on the enclosing member 1. In addition to sewing, welding and adhesion using an adhesive are also possible.

[0022] The outer surface connecting sheet 41 and the inner surface connecting sheet 42 of the connecting part 4 are preferably connected to the left and right ends of the side parts 2 and 3, as well as to positions along the ridge line at which the enclosing member 1 is folded. When the connection is performed by sewing, a sewing line S2 is formed along the ridge line for each connecting part 4. As shown in FIG. 2 and FIG. 3, a bag-shaped closed space for accommodating the plate-shaped reinforcing material 11 is provided between the outer surface connecting sheet 41 and the inner surface connecting sheet 42 of the connecting part 4. The closed space is provided so as to be spaced a predetermined distance W (for example, W=5 to 30 mm) from the ridge line at which the enclosing member 1 is folded. The plate-shaped reinforcing material 11 accommodated in the closed space is arranged so as to be parallel to the side ends of the side parts 2 and 3, one on each of the left and right sides of the side parts 2 and 3, at positions spaced a predetermined distance W from the folding position. The four ridge angles a, b, c, and d at the upper end are substantially formed by the outer surface connecting sheet 41 and the inner surface connecting sheet 42 that are superimposed. Similarly, the four corners e, f, c, and h at the lower end are substantially formed by the outer surface connecting sheet 41 and the inner surface connecting sheet 42 that are overlapped with each other.

[0023] The plate-shaped reinforcing member 11 is composed of a plastic plate-shaped portion 111 and an auxiliary rod 112 inserted into the hollow interior of the plate-shaped portion 111. The detailed structure of the plate-shaped reinforcing member 11 will be described with reference to Figs. 4(a) and 4(b). Fig. 4(a) is a plan view of the plate-shaped reinforcing member 11, and Fig. 4(b) is a front view of the plate-shaped reinforcing member 11. The plate-shaped reinforcing member 11 is composed of the plate-shaped portion 111 having a long hollow interior, and a rod-shaped or tubular auxiliary rod 112 inserted into the hollow interior. In this embodiment, the auxiliary rod 112 is composed of a solid member having a circular cross section.

[0024] The plate-shaped portion 111 includes two long flat plates 111a arranged at a predetermined interval, and a plurality of partition walls 111b arranged between the two flat plates 111a and connecting the two flat plates 111a. The plurality of partition walls 111b are arranged at a predetermined interval in the short direction of the flat plate 111a, and each partition wall 111b extends over substantially the entire length of the flat plate 111a in the longitudinal direction. The flat plates 111a and the partition walls 111b are integrally formed and made of, for example, a plastic material. The space defined by the two flat plates 111a and the two partition walls 111b is the hollow interior.

[0025] The auxiliary rod 112 is made of, for example, a plastic material, and extends over substantially the entire length of the plate-shaped portion 111 in the longitudinal direction. Note that the auxiliary rod 112 is not limited to a solid member with a circular cross section, and may be, for example, a cylindrical member, a rectangular column member, or a square tube member. By using materials with different elastic moduli and yield stresses for the plate-shaped portion 111 and the auxiliary rod 112, it is possible to obtain a sturdy enclosure member that can withstand external forces applied from the top, bottom, and side directions.

[0026] 1 and 2, the upper rod-shaped reinforcement members 12 arranged along the upper end portions of the side portions 2 and 3 will be described. A band-shaped upper bag body 5 is provided at the upper end portions of the side portions 2 and 3. The upper bag body 5 is preferably made of the same polyethylene sheet as the connecting portion 4. The upper bag body 5 is fixed to the upper end portions of the side portions 2 and 3 by sewing, for example. The upper rod-shaped reinforcement members 12 made of fiber-reinforced plastic are inserted inside the upper bag body 5. The four upper rod-shaped reinforcement members 12 impart rigidity to the ridgeline at the upper end portion of the enclosing member 1 when the enclosing member 1 is in a self-supporting state, and function to maintain the shape of the upper side of the enclosing member 1 in a square or diamond shape.

[0027] Similarly, a belt-shaped lower bag 6 is provided along the lower end of each of the four side portions 2, 3. The preferred material for the lower bag 6 is a polyethylene sheet, the same as that for the upper bag 5 and the connecting portion 4. Hereinafter, the upper bag 5 and the lower bag 6 will be collectively referred to as bags 5, 6. The lower bag 6 is fixed to the lower end of each of the side portions 2, 3, for example, by sewing. A lower bar-shaped reinforcement member 13 made of fiber-reinforced plastic similar to the upper bar-shaped reinforcement member 12 is inserted inside the lower bag 6. The four lower bar-shaped reinforcement members 13 impart rigidity to the ridgeline at the lower end of the enclosing member 1 when the enclosing member 1 is in a self-supporting state, and function to maintain the shape of the lower side of the enclosing member 1 in a square or diamond shape.

[0028] Each end of the upper rod-shaped reinforcement member 12 is housed inside the upper bag body 5 near the corners a, b, c, and d so as to leave a gap between adjacent upper rod-shaped reinforcement members 12 and to avoid direct contact with each other. Similarly, each end of the lower rod-shaped reinforcement member 13 is housed inside the lower bag body 6 near the corners e, f, g, and h so as to leave a gap between adjacent lower rod-shaped reinforcement members 13 and to avoid direct contact with each other. Therefore, when the enclosing member 1 is folded, the areas around all of the corners do not become bulky and the enclosing member 1 can be bent freely.

[0029] As explained above, the plate-shaped reinforcement 11 is housed between the outer surface connecting sheet 41 and the inner surface connecting sheet 42 of the connecting part 4, the upper rod-shaped reinforcement 12 is inserted inside the upper bag body 5, and the lower rod-shaped reinforcement 13 is inserted inside the lower bag body 6. As a result, the plate-shaped reinforcement 11, the upper rod-shaped reinforcement 12, and the lower rod-shaped reinforcement 13 are separated by the connecting part 4 and the bags 5 and 6, and do not come into contact with each other. With this structure, even if an unexpected force is applied from the outside, collisions between the reinforcements are prevented, and the risk of damage to the enclosing member 1 is avoided in advance.

[0030] Preferably, the enclosing member 1 can include one or more strings 21 connecting the lower end of the first side surface portion 2 and the lower end of the second side surface portion 3. The length of the strings 21 is set to a length that connects a mounting position on the first side surface portion 2 side with a mounting position on the second side surface portion 3 side in a straight line when the first side surface portion 2 and the second side surface portion 3 are arranged perpendicular to each other. By keeping the strings 21 in a straight line, the angle between the first side surface portion 2 and the second side surface portion 3 can be determined, and the shape of the enclosing member 1 in a self-supporting state during use can be stabilized.

[0031] 1 and 2, a display unit 7 can be provided on the first side surface portion 2. The display unit 7 is formed, for example, by attaching a rectangular flexible transparent plastic sheet to the first side surface portion 2 along the bottom and three sides, the left and right sides. By storing paper on which letters or figures are drawn in the display unit 7, the letters or figures can be displayed on the outer surface side of the first side surface portion 2.

[0032] 1, a handle 8 may be provided on the outer surface near the upper end of each of the two second side portions 3. Preferably, the handle 8 is fixed to the upper bag body 5 and is formed of, for example, a cloth or plastic band or string. The handle 8 is used when folding, unfolding, and transporting the enclosing member 1.

[0033] Hereinafter, a modified example of the surrounding member having a lid portion and an attachment / detachment assisting portion will be described. Fig. 5 shows a perspective view of the surrounding member 31. The same reference numerals are used for the portions having the same configuration as the surrounding member 1, and the description thereof will be omitted. do.

[0034] The lid 9 is preferably formed slightly larger than the opening formed by the upper ends of the side portions 2 and 3 of the enclosing member 31 so as to cover the entire opening. The lid 9 is formed of a flexible material in a rectangular or square shape in a mesh or sheet shape similar to the side portions 2 and 3, and is connected to one upper end of the first side portion 2 via a connecting portion 91. The connecting portion 91 can be formed of the same material as the connecting portion 4. At the three ends of the lid 9 that are not connected to the connecting portion 91, a rod-shaped reinforcing material is placed in a bag body 92, similar to the side portions 2 and 3. In addition, the lid 9 is provided with one side of a hook-and-loop fastener 93. At the first side portion 2 to which the lid 9 is not connected, the other hook-and-loop fastener 94 that forms a pair with the hook-and-loop fastener 93 is provided at a position that faces the hook-and-loop fastener 93 when the lid 9 closes the opening of the enclosing member 31. By rotating the lid 9 so that the hook-and-loop fastener 93 on the lid 9 side is connected to the hook-and-loop fastener 94 on the first side surface portion 2 side, the top opening of the enclosing member 31 can be closed by the lid 9.

[0035] Preferably, the enclosing member 31 can include an attachment / detachment auxiliary part 14 for detachably attaching the enclosing member 31 to an external structure such as a post or a fence. The attachment / detachment auxiliary part 14 is a sheet-like member fixed so as to protrude from the side of the enclosing member 31, and includes openings 14a such as eyelets so that the enclosing member 31 can be connected to an external structure using a string. By fixing and supporting the enclosing member 31 to an external structure, the strength required to stabilize the shape can be reduced, enabling further weight reduction.

[0036] By carrying out the folding procedure described below, the enclosing members 1, 31 can be made compact when not in use, with the side sections 2, 3 overlapping each other. As a means for maintaining the folded state, the enclosing members 1, 31 can be provided with fasteners 15. The fasteners 15 are preferably a pair of hook-and-loop fasteners. One fastener 15 is attached to one side edge, and the other fastener 15 is attached to the side edge diagonally opposite the side edge to which the one fastener 15 is attached.

[0037] An example of a procedure for transitioning the enclosing member 1, 31 from a freestanding state as shown in Fig. 1 and 5 to a folded state when not in use as shown in Fig. 7 will be described. The following steps are described for the enclosing member 31 in the case where a pair of fasteners 15 are attached to the side edge including corner angles a and e and the side edge including corner angles c and g. The enclosing member 1 can also be folded by a method that omits the first step of folding the lid portion.

[0038] When folding the enclosing member 31 from the self-supporting state of FIG. 5, in the first step, the lid portion 9 is rotated and overlapped so as to come into surface contact with the first side portion 2 to which the lid portion 9 is connected. In the second step, the two upper corners b and d of the enclosing member 31 are brought close to each other, and at the same time, the two lower corners f and h of the enclosing member 31 are brought close to each other. In the second step, the enclosing member 31 is folded so that the adjacent first side portion 2 and second side portion 3 are overlapped as shown in FIG. 6, and the side portions 2 and 3 form a V shape as a whole. In the third step, the two upper corners a and c are brought close to each other, and at the same time, the two lower corners e and g are brought close to each other. After the third step is completed, the fasteners 15 are overlapped to bring the side portions 2 and 3 and the lid portion 9 into a folded state in which they are overlapped, as shown in FIG. 7.

[0039] Thus, according to the enclosing member 1, 31 of this embodiment, the end portions on both the left and right sides of the side portions 2, 3 are provided with plate-shaped reinforcing members 11 extending parallel to these end portions, and the plate-shaped reinforcing members 11 are composed of a plastic plate-shaped portion 111 and an auxiliary rod 112 inserted into the hollow interior of the plate-shaped portion 111, thereby ensuring sufficient rigidity and allowing the enclosing member 1, 31 to stand on its own. Furthermore, the shape of the enclosing member 1, 31 according to the present invention is stabilized by the arrangement of the rod-shaped reinforcing members 12, 13 at the end portions on both the top and bottom sides of the side portions 2, 3.

[0040] Moreover, the plate-like reinforcing material 11 and the rod-like reinforcing materials 12, 13 are separated by the respective sheets of the connecting portion 4 and the bags 5, 6, and do not come into contact with each other. With this structure, even if an unexpected force is applied from the outside, collisions between the reinforcing materials are prevented, and the risk of damage to the enclosing members 1, 31 is avoided. EXAMPLES

[0041] [Example 1] Examples of the enclosing member of the present invention will be described. The first side portion 2 of Example 1 is formed of a mesh material made of ester tarpaulin with a width of 70 cm and a height of 70 cm. The second side portion 3 is formed of a mesh material made of ester tarpaulin with a width of 70 cm and a height of 70 cm. The connecting portion 4 and the bags 5 and 6 are formed of an ethylene sheet. The plate-shaped portion 111 of the plate-shaped reinforcing member 11 is formed of fiber-reinforced plastic, and the auxiliary rod 112 is formed of plastic. In addition, the rod-shaped reinforcing members 12 and 13 are formed of fiber-reinforced plastic. The enclosing member 1 of Example 1 has a capacity of about 340 liters.

[0042] [Example 2] The first side portion of Example 2 is formed of a mesh material made of ester tarpaulin with a width of 90 cm and a height of 70 cm. The second side portion is formed of a mesh material made of ester tarpaulin with a width of 60 cm and a height of 70 cm. The connecting portion and the bag body are formed of polyester. The plate-shaped portion of the plate-shaped reinforcing material is formed of fiber-reinforced plastic, and the auxiliary rod is formed of plastic. In addition, the rod-shaped reinforcing material is formed of fiber-reinforced plastic.

[0043] In this embodiment, the first side portion is formed of two identical mesh members having a width of 45 cm and a height of 70 cm. The same joint portion as that used to join the first side portion and the second side portion is additionally disposed in the center of the first side portion, and the first side portion is formed by arranging two mesh members in parallel on each side of the joint portion and joining the ends. In the central joint portion of the first side portion, a plate-shaped reinforcing material is preferably disposed inside the space formed by the outer surface connecting sheet and the inner surface connecting sheet. In addition, a bag body can be formed by a sheet of the same material as the joint portion at the upper end and lower end of the first side portion and the second side portion, and a rod-shaped reinforcing material can be disposed therein. The rod-shaped reinforcing material disposed in the first side portion may be one piece, or alternatively, rod-shaped reinforcing materials of different members can be disposed on both the left and right sides of the additional joint portion disposed in the center. Since the widths of the first side portion and the second side portion are different, the enclosure member of Example 2 is preferably stored in a folded state when not in use. The enclosing member 1 of Example 2 has an internal volume of about 380 liters.

[0044] Although the enclosing member of the present invention has been described above by way of example, the present invention includes various enclosing members other than the enclosing members of the embodiments and examples described in the specification. For example, the examples show an enclosing member having square side portions 2, 3 and an enclosing member having a first side portion 2 and a second side portion 3 of different sizes, but the present invention can also be implemented with an enclosing member having the first side portion 2 and the second side portion 3 of the same shape but different width and height dimensions. In addition, in the embodiment, the case where the connecting portion 4 and the bag bodies 5, 6 are formed from a single sheet material has been described, but it is also possible to appropriately add reinforcing parts to the ends of the connecting portion 4 and the bag bodies 5, 6. In particular, reinforcing members can be appropriately added to the lower corners e, f, g, and h. [Explanation of symbols]
