For example, if this space is filled with heavy materials such as earth and sand, it can be used during a flood. The present invention relates to a foldable box that can be applied for multipurpose purposes such as water blocking, river bank protection, road slope construction, and the like.

  Conventionally, there are those shown in Patent Documents 1 and 2 below as the folding box. According to these publications, the folding box is located in a space between the pair of side walls extending in one horizontal direction and facing each other in a direction orthogonal to the one direction, and both side walls. A partition wall extending in the orthogonal direction and partitioning the space into a plurality of partition spaces in the one direction; and a hinge for pivotally supporting each end edge of the partition wall in the orthogonal direction on the side walls. .

  Each of the side walls includes a plurality of side wall elements arranged in the one direction, and another hinge that pivotally supports the opposing end edges of the pair of side wall elements adjacent in the one direction. . Further, opposing edge portions of the pair of side wall elements adjacent to each other in the one direction and the other pair of side wall elements are pivotally supported by the hinge.

  When the box is not used, the side walls are rotated relative to each other about the hinges, and the side walls and the partition wall are rotated relative to each other. Each of the side wall elements and the partition wall can be folded while being contracted in a bellows shape in one direction. Thereby, the box can be folded into a compact shape.

  On the other hand, when the box is used, the box is expanded and expanded in the one direction so that the space inside the box is expanded.

  By the way, as described above, it is assumed that a certain object is formed by filling a heavy material such as earth and sand into an internal space when the box is used. In this case, a large internal pressure is applied to the inner surface of each side wall element of the box from the weight material. Then, due to the internal pressure, the opposing edge portions of the pair of side wall elements rotate relative to each other about the other hinge, and the opposing edge portions face the outer side of the box body in the orthogonal direction. Tend to protrude. In other words, the side wall is unintentionally zigzag-shaped toward the one direction due to the internal pressure from the weight material, so that there is a problem that it is not easy to make the object into a desired shape.

  In addition, the other hinges tend to be concentrated due to a large tensile force due to the internal pressure from the heavy material.

  Here, each of the side wall elements includes a plurality of vertically oriented wires arranged at equal intervals in the one direction and a plurality of horizontally oriented wires arranged at equal intervals in the vertical direction and welded to the vertically oriented wires. Therefore, based on this configuration, in order to improve the strength of the other hinges, it is conceivable to make the following as a temporary configuration.

  That is, the opposing end portions of the lateral wires of the pair of side wall elements adjacent in the one direction are bent into ring-shaped portions. On the other hand, the other hinge includes a pair of vertically oriented bars arranged side by side in the one direction, and a coil-shaped (or annular) wire that is externally fitted to both the vertically oriented bars. To. Then, the ring-shaped portions of the horizontal wires are externally fitted to the vertical bars, and the vertical bars and the ring-shaped portions of the horizontal wires are welded. If it does in this way, the structure as said hinge will be materialized and the intensity | strength can fully be improved.

  However, when the other hinges have the above-described provisional configuration, the configuration of the other hinges is complicated, and accordingly, the configuration of the box is complicated and the forming operation is complicated. In addition, it is considered undesirable to be expensive.

  The present invention has been made paying attention to the above-mentioned circumstances, and the object of the present invention is to develop a folding box and to fill a space inside thereof with a heavy material such as earth and sand. If the inner surface of the box is given a large internal pressure from the weight material, the object can be formed in a desired shape.

  Another object of the present invention is to make it possible to simplify the structure of the box and to make the forming operation easy and inexpensive.

The invention of claim 1 is located in a space 7 between the pair of side walls 6 and 6 that extend in one horizontal direction X and face each other in the direction Y orthogonal to the one direction X. And the partition wall 8 extending in the orthogonal direction Y and partitioning the space 7 into the plurality of partition spaces 7a in the one direction X, and the respective edge portions of the partition wall 8 in the orthogonal direction Y on the side walls 6 In the folding box provided with the first hinges 9 to be pivoted,
Each of the partition walls 8 pivotally supports a plurality of partition wall elements 12 arranged in the orthogonal direction Y and the opposing edge portions of the partition wall elements 12 and 12 adjacent in the orthogonal direction Y. A second hinge 13 ;
The side wall 6 and each partition wall element 12 of the partition wall 8 are respectively formed of a wire mesh 16 or a water-permeable plate material, and a film body 21 is provided to cover the side wall 6 and the partition wall 8 from the partition space 7a side. ,
Of the partition walls 8 (A) and (B), an opening is formed in the portion of the film body 21 that faces the midway portion in the orthogonal direction Y in the midway partition wall 8 (B) in the one direction X. 22 is a foldable box body in which 22 is formed .

The invention of claim 2 is a foldable box of claim 1, the reinforcing bar 25 extending toward the one direction X is equal to or attached to the side wall 6.

  In addition, in this section, the reference numerals and drawing numbers appended to the above terms are not intended to limit the technical scope of the present invention to the “Example” section and the contents of the drawings described later.

  The effects of the present invention are as follows.

The invention according to claim 1 is located in a space between the pair of side walls extending in one horizontal direction and facing each other in a direction orthogonal to the one direction, and both side walls, and extends in the orthogonal direction. A folding box comprising: a partition wall that divides the partition wall into a plurality of partition spaces in the one direction; and first hinges that pivotally support the end edges of the partition wall in the orthogonal direction on the side walls, respectively.
Each of the partition walls includes a plurality of partition wall elements arranged in the orthogonal direction, and a second hinge pivotally supporting the opposing edge portions of the partition wall elements adjacent in the orthogonal direction. Yes.

  Therefore, when the box is not used or transported, the partition wall elements of the partition walls are rotated relative to the side walls around the first hinges of the box, and If the partition wall elements of the partition walls are rotated relative to each other about the second hinge, the side walls and the partition wall elements are moved in the orthogonal direction while the side walls are brought close to each other in the orthogonal direction. Can be folded at. Thereby, the said box can be folded into a compact shape.

  On the other hand, when the box body is expanded so that each partition space that is the space inside the box body is expanded, and each partition space is filled with a heavy material such as earth and sand, and an object for embankment or earth retaining is formed. To do. In this case, each side wall of the box body may be deformed by applying a large internal pressure to the inner surface from the weight material.

  However, according to the above invention, each side wall is not provided with a hinge as in the prior art, and each side wall is an integral rigid body. For this reason, it is prevented that a part of each said side wall deform | transforms so that it may protrude toward the outer side of a box in the said orthogonal direction due to the internal pressure from the said heavy material. Therefore, the object can be formed into a desired shape.

  Furthermore, as described above, since each side wall is an integral rigid body, there is no other hinge as described in the prior art. In order to improve the strength, it is not necessary to use a complicated temporary structure as described in the related art.

  Therefore, since the configuration of each of the side walls is sufficient, the configuration of the box is simplified accordingly, and accordingly, the formation of the box can be easily and inexpensively achieved. It is extremely useful in practice.

In the invention of claim 1, also with the partition wall elements of the side wall and the partition wall is formed of a plate material of metal gauze or water-permeable, respectively, film for covering the side walls and the partition walls from each partitioned space side It is provided.

If the side wall in the upper Symbol box member and the partition wall element is formed by a wire mesh, as compared to forming them of a plate material, its handling can be easily made the box body weight. Therefore, the operation | work which expand | deploys the said box and fills each division space with a heavy material and forms a target object can be done more easily.

Then, as described above, when the object is formed by filling each compartment space of the box body with the weight material, the weight material leaks out of the box body through the wire mesh or the water-permeable plate material. Is prevented by the film body. Therefore, as described above, the box can be reduced in weight, but the object formed using the box can be maintained in a desired shape over a long period of time.

In the invention of claim 1, also among the respective partition walls, an opening in a portion of the film body facing to middle portion in the orthogonal direction in the partition wall of the intermediate portion in the one direction is formed Yes.

  For this reason, when each compartment space of the box is filled with a weight material, the weight material is the opening that is a boundary portion between both compartment spaces adjacent in one direction, and the wire mesh of the partition wall facing the opening. The mesh portion is also filled. Therefore, the space inside the box is filled with the weight material as a whole, and the properties of the object formed by the box and the weight material are more uniform with each other in each part in the one direction. Can be. As a result, when this object is used, for example, for embankments or earth retaining, water is unnecessary in each part of the object in one direction including the boundary between the two compartment spaces in the orthogonal direction. Permeation into the water is prevented, that is, the performance of the object as a dike or earth retaining can be made high quality.

  In addition, as described above, the opening is formed in the middle portion in the orthogonal direction of the film body at the boundary portion between both compartment spaces adjacent in one direction. For this reason, when the object is used for embankment or earth retaining, the weight material flows out from the inside of each partition space through the boundary between the both partition spaces. This is prevented by the end portions of the film body in the orthogonal direction at the boundary portion of the space, and in this respect also, the performance of the object can be made high quality.

The invention of claim 2, the reinforcing bars extending toward the one direction is attached to the side wall.

  For this reason, the said side wall is reinforced with the said reinforcement bar, and the integral rigidity improves more. Therefore, when an object is formed by filling each compartment space of the box body with a weight material, a part of the side wall is directed outward of the box body in the orthogonal direction due to the internal pressure from the weight material. Therefore, it is more reliably prevented from deforming so as to protrude. For this reason, it is more reliably achieved to form the object in a desired shape.

  Further, when the box is folded so as to have a compact shape as described above, or when the box is expanded so that each of the partition spaces is expanded, the side wall is an integral rigid body and the shape thereof changes. do not do. For this reason, even if a reinforcing bar is attached to the side wall for reinforcing the side wall as described above, the reinforcing bar is prevented from interfering when the box is folded or unfolded. Therefore, as described above, the side wall is reinforced by the reinforcing bar to more reliably achieve the desired shape, and the box can be easily and smoothly folded and unfolded. There is.

It is a perspective view at the time of use of a box. It is a side view. It is a top view. FIG. 4 is an enlarged detail view of a part IV in FIG. 3. It is the top view which folded up the box.

  When a foldable box is developed with respect to the foldable box of the present invention, and a space material is filled with heavy materials such as earth and sand to form an object, the inner surface of the box is larger than the weight material. In order to realize the object of enabling a target object to be formed in a desired shape even when an internal pressure is applied, a mode for carrying out the present invention is as follows.

  That is, the folding box extends in one horizontal direction, is located in a space between the pair of side walls facing each other in a direction orthogonal to the one direction, and both side walls, and extends in the orthogonal direction. A partition wall that partitions the space into a plurality of partition spaces in the one direction, and a first hinge that pivotally supports each end edge of the partition wall in the orthogonal direction on the side walls. Each of the partition walls includes a plurality of partition wall elements arranged in the orthogonal direction, and a second hinge that pivotally supports the opposing edge portions of the partition wall elements adjacent in the orthogonal direction.

  In order to explain the present invention in more detail, an embodiment thereof will be described with reference to the accompanying drawings.

  1-4, the code | symbol 1 in a figure is a foldable box. The box 1 is formed on the ground G, and is filled with a heavy material 2 such as earth and sand to enable formation of various objects 3 such as an embankment, earth retaining, and embankment. .

  The box body 1 extends in a certain horizontal direction X, and in a space 7 between the pair of side walls 6 and 6 facing each other in the horizontal orthogonal direction Y to the one direction X, and both side walls 6 and 6.

  The side walls 6 and the partition walls 8 extend in parallel with each other, have the same shape and the same size, and the partition walls 8 are arranged at equal intervals in the one direction X. For this reason, each said partition space 7a is mutually made the same shape and the same size.

  Each partition wall 8 is configured such that a plurality (a pair) of partition wall elements 12 and 12 arranged in the orthogonal direction Y and the partition wall elements 12 and 12 adjacent in the orthogonal direction Y are opposed to each other. The second hinge 13 pivotally supports the end edges.

  Each of the side walls 6 has a rectangular shape that is long in the one direction X in a side view of the box 1 (FIG. 2), and specifically has a height × length of 1 m × 3 m. Each partition wall 8 has a square shape having the same height as the side wall 6 in a front view of the box 1. For this reason, the said box 1 has comprised the rectangular parallelepiped shape long in the said one direction X as a whole. The partition wall elements 12 have the same shape and the same size, and have a rectangular shape that is long in the vertical direction when the box 1 is viewed from the front.

  The side wall 6 and each partition wall element 12 of the partition wall 8 are each formed of a wire mesh 16. The wire mesh 16 includes a plurality of vertical wires 17 arranged at equal intervals (75 mm intervals) in the one direction X and a plurality of horizontal wires 18 arranged at equal intervals (75 mm intervals) in the vertical direction. Have. Each of the vertical wire 17 and the horizontal wire 18 has a diameter of 4 mm and is hot dip galvanized, and is firmly bonded to each other by welding or the like and has a square mesh.

  The first and second hinges 9 and 13 are formed by winding a metal wire around a pair of longitudinal wires 17 and 17 that form opposing end edges of the adjacent metal meshes 16 and 16 so as to form a coil shape. Is. In addition, the said 1st, 2nd hinges 9 and 13 may be a ring-shaped thing provided with two or more by the up-down direction, and may use a commercial item.

  A film body 21 is provided to cover each side wall 6 and each partition wall 8 from the partition space 7a side. These film bodies 21 are integrally formed for each of the partition spaces 7a, and are connected to and supported by the side walls 6 and the partition walls 8. When each of the film bodies 21 is filled with the weight material 2 in each of the partition spaces 7a to form a certain target object 3, the weight material 2 passes through the mesh of the wire mesh 16 to the outside of the box body 1. This prevents leakage. The film body 21 is a non-woven fabric made of natural fibers, synthetic fibers or the like having water permeability. The membrane 21 is made of natural fiber, synthetic fiber or the like, or vinyl chloride (PVC), polyurethane (PU), ethylene / vinyl acetate co-polymerized on at least one surface of both surfaces of the fabric. Those provided with a coating material made of a synthetic resin such as coalescence (EVA) can also be used, and may be formed of a water-permeable or water-permeable sheet material.

  In the above case, of the plurality of (four) partition walls 8 (A) and (B) included in the box 1, the two partition walls 8 (A) located at the end in the one direction X are as follows. The surface of each partition space 7a is covered with the film body 21 as a whole.

  On the other hand, among the plurality of partition walls 8 (A) and (B) described above, the plurality of (two) partition walls 8 (B) positioned in the middle portion in the one direction X are respectively in the orthogonal direction Y. An opening 22 is formed in the part of the film body 21 that faces the middle part of the film in the entire vertical direction. The partition spaces 7 a and 7 a adjacent to each other in the one direction X are communicated with each other through the opening 22 and the portion of the partition wall 8 facing the opening 22.

  As indicated by a two-dot chain line in each figure, a reinforcing bar 25 that extends linearly toward the one direction X and is attached to the side walls 6 to reinforce the side walls 6 is provided.

  A plurality of the reinforcing bars 25 are provided in the vertical direction, and each reinforcing bar 25 is firmly attached to the side wall 6 by a metal wire or the like. The reinforcing bar 25 is formed of a metal bar having a circular cross section, but the cross section may be rectangular or polygonal, or may be formed of a steel mold.

  In FIG. 5, when the box 1 having the above configuration is not used or transported, the partition wall elements of the partition walls 8 with respect to the side walls 6 around the first hinges 9 of the box 1. When the partition wall elements 12 and 12 of the partition walls 8 are relatively rotated around the second hinge 13, the side walls 6 and 6 are moved in the orthogonal direction Y. The side walls 6 and the partition wall elements 12 can be folded in the orthogonal direction Y while being brought close to each other. Thereby, the box 1 can be folded into a compact shape.

  When the box body 1 is folded as described above, the side walls 6 are kept in a fixed shape as an integral rigid body, while the partition wall 8 has a pair of partition wall elements 12 and 12 that are connected to the second hinge 13. Folds with relative rotation as the center.

  Here, when the box 1 is folded as shown in FIG. 5, a pair of folded partition wall elements 12, 12 and another pair of partition wall elements 12, 12 adjacent to each other in the one direction X, The lengths in the one direction X of the pair of partition wall elements 12 and 12 that are folded are determined so that they do not interfere with each other. In this case, the maximum length of the folded pair of partition wall elements 12 and 12 in one direction X is close to the pitch dimension (1 m) of each partition wall 8 in the one direction X. it can.

  And if the length in the said one direction X of a pair of folded partition wall element 12 and 12 is made into the said maximum value as mentioned above, the said orthogonal of the said partition wall 8 in the box 1 when it expand | deploys The dimension in the direction Y can be increased to a dimension (2 m) that is almost twice the pitch dimension (1 m) of each partition wall 8 in the one direction X. Therefore, according to the box 1 having the above configuration, the folding can be performed without difficulty and the capacity at the time of deployment can be increased. Therefore, the stability of the object 3 formed by the box 1 can be improved. .

  1 to 4, when the box 1 is used, the pair of side walls 6 and 6 are separated from each other in the orthogonal direction Y so that each partition space 7a is expanded. And if each said division space 7a is filled with heavy materials 2, such as earth and sand, it can form in the various objectives 3 for embankments, earth retaining, and embankment. Specifically, the object 3 can be applied for various purposes to block water 28 such as floods, river protection works such as rivers, and road slope works.

  According to the above configuration, the partition walls 8 are opposed to each other between the plurality of partition wall elements 12 arranged in the orthogonal direction Y and the partition wall elements 12 and 12 adjacent in the orthogonal direction Y. And a second hinge 13 that pivotally supports the edge.

  Here, the box body 1 is expanded so that each partition space 7a which is the space 7 inside the box body 1 is expanded, and each partition space 7a is filled with a heavy material 2 such as earth and sand, for embankment or earth retaining. It is assumed that the object 3 is formed. In this case, each side wall 6 of the box 1 may be deformed by applying a large internal pressure from the weight material 2 to the inner surface thereof.

  However, according to the above configuration, each side wall 6 is not provided with a hinge as in the prior art, and each side wall 6 is formed as an integral rigid body. For this reason, it is prevented that a part of each said side wall 6 deform | transforms toward the outer side of the box 1 in the said orthogonal direction Y due to the internal pressure from the said weight material 2. FIG. Therefore, the object 3 can be formed into a desired shape.

  Furthermore, as described above, each side wall 6 is formed as an integral rigid body. Therefore, there is no other hinge as described in the above-mentioned conventional technology. In order to improve the strength, it is not necessary to use a complicated temporary structure as described in the related art.

  Therefore, since the configuration of each of the side walls 6 is simple, the configuration of the box body 1 is simplified correspondingly, and accordingly, the operation of forming the box body 1 can be achieved easily and inexpensively, This is extremely useful in practice.

  Further, as described above, the side wall 6 and each partition wall element 12 of the partition wall 8 are formed by the wire mesh 16, respectively, and the film body 21 that covers the side wall 6 and the partition wall 8 from the side of each partition space 7a is provided. ing.

  For this reason, since the side wall 6 and each partition wall element 12 in the said box 1 are formed with the metal mesh 16, compared with forming these with a board | plate material, the box 1 can be made lightweight and the handling can be performed easily. . Therefore, the operation of expanding the box 1 and filling the respective partition spaces 7a with the weight material 2 to form the target object 3 can be facilitated.

  When the object 3 is formed by filling the respective partition spaces 7a of the box 1 with the weight material 2 as described above, the weight material 2 leaks out of the box 1 through the mesh of the wire mesh 16. This is prevented by the film body 21. Therefore, as described above, the box 1 can be made light, but the object 3 formed using the box 1 can be maintained in a desired shape over a long period of time.

  Further, as described above, an opening is formed in each partition wall 8 in the portion of the film body 21 facing the midway portion in the orthogonal direction Y in the midway partition wall 8 (B) in the one direction X. 22 is formed.

  For this reason, when each partition space 7a of the box 1 is filled with the weight material 2, the weight material 2 includes the opening 22 which is a boundary portion between the two partition spaces 7a and 7a adjacent in one direction X, and the opening 22 The mesh portion of the metal mesh 16 of the partition wall 8 facing the opening 22 is also filled. Therefore, the space 7 inside the box 1 is filled with the weight material 2 as a whole, and the property of the object 3 formed by the box 1 and the weight material 2 is set in the one direction. Each part of X can be made more uniform with each other. As a result, when this object 3 is used, for example, for embankments or earth retaining, the water 28 is present in each part in the one direction X of the object 3 including the boundary between the two compartment spaces 7a, 7a. Unnecessary transmission in the orthogonal direction Y is prevented, that is, the performance of the object 3 for embankment or earth retaining can be made high quality.

  Further, as described above, the opening 22 is formed in the middle portion in the orthogonal direction Y of the film body 21 at the boundary portion between the two partition spaces 7a and 7a adjacent in the one direction X. For this reason, when the object 3 is used for embankment or earth retaining, the weight material 2 flows out from the inside of each partition space 7a to the outside of the object 3 through the boundary between the both partition spaces 7a and 7a. This is prevented by the respective end portions in the orthogonal direction Y of the film body 21 at the boundary portion between the two partition spaces 7a and 7a, and in this respect also, the performance of the object 3 can be made high quality. .

  When a plurality of objects 3 are densely arranged in the one direction X and maintained (two-dot chain lines in FIGS. 1 and 2), both objects adjacent in the one direction X As described above, the openings 22 may be formed in the portions of the film bodies 21 at the boundary portions 3 and 3. In this way, as described above, the property of each part in the one direction X of the target object 3 including the boundary portion between the two compartment spaces 7a and 7a adjacent in the one direction X in the one target object 3 is further improved. The two objects that are arranged side by side as described above are the same as the effect that can be made uniform or can prevent the flow of the weight material 2 from the inside of each partition space 7a of the object 3 to the outside. 3, 3 can also be obtained.

  Further, as described above, the reinforcing bar 25 extending in the one direction X is attached to the side wall 6.

  For this reason, the said side wall 6 is reinforced with the said reinforcement bar 25, and the integral rigidity improves more. Therefore, when the target material 3 is formed by filling each partition space 7 a of the box 1 with the weight material 2, a part of the side wall 6 is in the orthogonal direction Y due to the internal pressure from the weight material 2. It is more reliably prevented from being deformed so as to protrude toward the outer side of the box 1. For this reason, it is more reliably achieved to form the object 3 in a desired shape.

  Further, when the box body 1 is folded so as to have a compact shape as described above, or when the box body 1 is expanded so that each of the partition spaces 7a is expanded, the side wall 6 is an integral rigid body. Its shape does not change. For this reason, even if the reinforcing bar 25 is attached to the side wall 6 for reinforcing the side wall 6 as described above, the reinforcing bar 25 is prevented from interfering when the box 1 is folded or unfolded. Therefore, as described above, the side wall 6 is reinforced by the reinforcing bar 25 and the object 3 can be more reliably formed into a desired shape, but the box 1 can be folded and unfolded easily and smoothly. There is an advantage that can be.

  On the other hand, the film body 21 has a vegetation base function that allows the plant 31 to grow, and the outer surface of the object 3 can be greened. Specifically, the film body 21 has a mesh shape or a sponge (sponge) shape, and can hold fertilizers and rhizomes necessary for vegetation.

  In the above case, a film body 21 having the same property as above may be provided on the upper surface of the object 3, that is, the upper surface of the filled weight material 2, so that the upper surface of the object 3 can be greened. Further, it is preferable to provide a water-retaining material at least partly or entirely between each of the side walls 6 and the film body 21, and the water 28 can be absorbed and supplied to the object 3. A water hose may be installed on the object 3.

The above is due to the illustrated example, the partition wall element 12 of the side wall 6 and the partition wall 8 may be formed of a plate material made of metals made or resin, even those water-permeable these plate materials as porous Good. Further, the partition wall element 12 included in the partition wall 8 may be three or more. Further, the partition space 7a may be four or more. Further, the film body 21 may be provided so as to close the lower end opening of the space 7 or each partition space 7a.

  In addition, a picture, a figure, or a pattern may be drawn or printed on the outer surface of the film body 21. In this way, harmony with the surrounding environment can be achieved, and passers-by around the object 3 can be obtained. Can improve the impression.
