Description

[Technical field]

[0001] The present invention relates to a corrugated board assembly device and a manufacturing method thereof. [Background technology]

[0002] Lifestyles are changing in response to changes in the external environment, and more and more people are enjoying themselves at home. Also, when the weather is bad, children who like playing outside are enjoying playing indoors. For example, building a "house"-like space indoors and playing pretend games is one of the indoor games that everyone can enjoy as they were when they were young.

[0003] By dismantling unnecessary cardboard boxes and cutting them into boards, propping them up with chairs, leaning them against furniture, or sticking them together with duct tape, a structure can be made to create a "house"-like space indoors. However, the resulting space can be unstable or narrow, making it difficult to create a comfortable play space.

[0004] The following Patent Document 1 discloses a cardboard tube connector 101 that can improve the design freedom in the framework design of a structure 104 assembled from cardboard boards 103, such as a children's playhouse, individual rooms for adults, individual rooms in a disaster evacuation shelter, etc., as shown in FIG. 20.

[0005] Specifically, the cardboard tube connector 101 shown in FIG. 21 includes a cardboard tube connector 101 having a polyhedral base 110, two or more male side protrusions 111-115 that protrude from two or more of all the faces of the base and that are to be inserted into the central hole 121 of the target cardboard tube 102 and press-fitted, and a female side recess 116 that opens into one of all the faces of the base 110 where no male side protrusions exist and that is to receive similar male protrusions 111-115 of another cardboard tube connector 101 and press-fit therein.

[0006] According to this configuration, the cardboard tube connectors 101 can be directly connected to each other via a press-fit between the male protrusions 111-115 of one cardboard tube connector 101 and the female recess 116 of one cardboard tube connector 101 having any other shape. This, combined with the basic structure of the cardboard tube connector 101 itself (the other cardboard tube connector may be two straight connections, two right-angle connections, three right-angle connections, four cross-strip connections, etc.), greatly improves the design freedom in the skeleton design of the structure 104 using the cardboard tubes 102.

[0007] The following Patent Document 2 discloses knockdown furniture 200, such as a bed or a bench, which has a simple structure as shown in FIG. 22 and can be easily assembled and disassembled.

[0008] Specifically, the knockdown furniture 200 includes two peripheral sleeve bodies 201, two lattice bodies 202, and two top plates 204, each made of corrugated cardboard. The peripheral sleeve body 201 is formed in a rectangular tubular shape in a plan view. The lattice body 202 is formed by assembling a plurality of plate-shaped boards in a lattice shape and is housed in the peripheral sleeve body 201. The top plate is formed in a rectangular plate shape in a plan view that covers the lattice body 202. A wall body 205 is inserted between the peripheral sleeve body 201 and the lattice body 202. The wall body 205 is made of a corrugated cardboard plate-shaped body that stands on the top plate. The two peripheral sleeve bodies 201 are disposed adjacent to each other and connected by a connector 206. In this way, the knockdown furniture 200 has a simple structure, and each of the assembly and disassembly operations can be easily performed.

[0009] The following Patent Document 3 discloses a magnetic plate toy 301, as shown in FIG. 23, which is made of durable plastic and easy to assemble, allowing for a wide variety of connection methods and cultivating children's creativity and imagination through play.

[0010] Specifically, FIG. 24 is a perspective view showing a part of a magnetic plate toy 301 according to an embodiment in which the first magnet 302 and the second magnet 303 are columnar. As an example, the first magnet 302 and the second magnet 303 are quadrangular columnar with a rectangular bottom, particularly square columnar with a square bottom, and are made of the same material, for example, a neodymium magnet. The first magnet 302 and the second magnet 303 have a magnetization direction perpendicular to the axial direction, and are divided into two in the direction perpendicular to the axial direction. The first magnet 302 has an N pole portion disposed on one side of the direction perpendicular to the axial direction, and an S pole portion disposed on the other side of the direction perpendicular to the axial direction. The dimensions (volume) and magnetic force of the second magnet 303 are, for example, larger than the dimensions and magnetic force of the first magnet 302. In the magnetic plate toy 301 configured as above, the first magnet 2 is accommodated in the first accommodation portion 321 so as to be movable along the side portion 304a of the plate member 304. Therefore, it is possible to connect with other magnetic plate toys over a wide range of the side portion 304a. With the other magnetic plate toy still connected to the side portion 304a of the magnetic plate toy 301, it is also possible to move (slide) the other magnetic plate toy along the side portion 304a.

[0011] Moreover, the following Patent Document 4 discloses a magnetic plate toy 401 that allows for a wide variety of play styles, as shown in FIG.

[0012] Specifically, the magnetic plate toy 401 includes a first plate 410 and a second plate 430 arranged opposite each other, and a connecting portion 450 extending in the opposing direction D of the first plate 410 and the second plate 430 and connecting the first plate 410 and the second plate 430. The first plate 410 includes a first plate member 411 and a plurality of first magnets provided inside the first plate member 411, and the second plate 430 includes a second plate member 431 and a plurality of second magnets provided inside the second plate member 431 corresponding to the plurality of first magnets. The second plate 430 is connected to the connecting portion 450 so as to be rotatable with the opposing direction D as the rotation axis direction. The first magnet 412 and the second magnet 432 are provided on the edge portion of the first plate member 411 and the edge portion of the second plate member 431, respectively, so that other magnetic plate members can be joined to each edge portion. This allows for more varied ways of playing. [Prior art documents] [Patent documents]

[0013] [Patent Document 1] JP 2019-184009 A (cardboard tube connecting device) [Patent Document 2] Publication No. 3222348 (assembly furniture) [Patent Document 3] JP 2019-130237 A (magnetic plate toy) [Patent Document 4] JP 2020-157008 A (Magnetic plate toy) Summary of the Invention [Problem to be solved by the invention]

[0014] However, in the invention of Patent Document 1, if there are not enough cardboard tube connectors 101, the plate materials cannot be connected and further three-dimensional structures cannot be constructed, so it is necessary to procure additional cardboard tube connectors 101. In addition, since it is difficult for young children to use the cardboard tube connectors 101 to form the plate materials 103 into the three-dimensional structure 104, there is a problem that they tend to avoid playing with it with a sense of speed.

[0015] In addition, the invention of Patent Document 2 is a prefabricated furniture 200 that constitutes a chair or bed that allows personal space to be secured. However, because it is assembled from an outer sleeve body 201, a lattice body 202, a top plate 204, and a wall body 205, there is a problem that it is difficult to easily change the size.

[0016] Furthermore, in the invention of Patent Document 3, plate member 304 of magnetic plate 301, which is an educational toy to be played with at hand, is made of plastic, so it is difficult to make it large enough to "play in an assembled structure," and if it is made large, the size of magnetic plate 301 and the number of plates used will increase, resulting in increased weight and unstable connections, increasing the danger to players. Furthermore, when disposing of plate members 411 and 431, there is a problem that recycling is difficult and puts a strain on the environment.

[0017] The invention in Patent Document 4 has the following problems: since it is made of plastic, it is difficult to modify it by drilling holes in it, an oil-based writing implement is required to write on the surface, which limits the implements that can be used, and the ink uses a solvent, which is environmentally hazardous.

Fig. 11 shows the box-X rectangular parallelepiped 27, and Fig. 12 shows the box-Y triangular prism 28. By placing the box-X rectangular parallelepiped 27 between the boxes 11 and 11 (the box-A large rectangular parallelepiped 21 and the box-A large rectangular parallelepiped 21 in Fig. 10), the magnet 61 in the magnet cartridge 51 attached to the box-cut hole 14 provided on the side of the box-A large rectangular parallelepiped 21 and the magnet 61 in the magnet cartridge 51 attached to the box-cut hole 14 provided on the side of the box-X rectangular parallelepiped 27 or the box-Y triangular prism 28 attract each other and connect at a right angle.

[0038] 14 is an explanatory diagram showing the joining state of the magnetic cartridge 41 and the box outer box 32 and the box inner box 33 of the stacked box 31 in the third embodiment of the cardboard assembly device of the present invention. A box body cutout hole 34 is provided on the surface of the box inner box 33. The magnetic cartridge cover 42 side of the magnetic cartridge 41 is inserted into the box body cutout hole 34. The box body cutout hole 34 is inserted into the magnetic cartridge receiver 45 of the magnetic cartridge receiver 45. Rising part The outer box 32 is sized to be in contact with the outer periphery of the inner box 33 without any gaps, and is fitted into the inner box 33 with the magnetic cartridge 41 fitted in, to form the stacked box body 31.

[0039] 15 is an explanatory diagram showing the connection structure of stacked boxes 31 in the third embodiment of the cardboard assembly device of the present invention. The magnet cartridge lid 42 side of the magnet cartridge 41 is inserted into the box cutout hole 34 provided on the surface of the box inner box 33, and the box outer box 32 of a size that fits snugly around the outer periphery is attached to form the stacked box 31. By displacing the part of one stacked box 31 into which the magnet cartridge 41 is fitted and the part of the other stacked box 31 into which the magnet cartridge 41 is fitted so that they come into contact with each other, the stacked boxes 31 are connected to each other by the magnetic force of the magnets 61 inside the magnet cartridge 41.

[0040] 16 is an explanatory diagram showing a cross-sectional structure of the components of a magnetic cartridge 41 of a third embodiment of the cardboard assembly device of the present invention before assembly. The magnetic cartridge 41 is composed of a magnetic cartridge cover 42 and a magnetic cartridge receiver 45. The magnetic cartridge cover 42 and the magnetic cartridge receiver 45 may be attached with an adhesive or the like.

[0041] The magnet cartridge receiver 45 is a magnet cartridge receiver that stands upright approximately vertically from the outer frame of the bottom surface 48 of the magnet cartridge receiver. Rising part 49. Magnetic cartridge receiver Rising part The outer side of the magnet cartridge receiver flange surface 46 is the magnet cartridge receiver bottom surface 48. Rising part The outer portion of 49 serves as the rear surface 47 of the flange for receiving the magnetic cartridge.

[0042] The magnetic cartridge lid 42 is substantially rectangular with five sides and one opening. Its outer side is an outer wall 43 of the magnetic cartridge lid, and its inner side is an inner wall 44 of the magnetic cartridge lid.

[0043] The magnetic cartridge 41 is arranged such that the magnetic cartridge lid outer wall 43 near the opening of the magnetic cartridge lid 42 is in contact with the magnetic cartridge receiver 45. Rising part The shape and size of the outer and inner periphery of the magnet cartridge 41 are the same as that of the magnet cartridge holder 45, so that they fit snugly into the inner surface of the magnet cartridge 41. Before fitting the magnet cartridge cover 42 into the magnet cartridge holder 45, the magnet 61 is inserted into the magnet cartridge holder 45, and the magnet 61 is contained inside the magnet cartridge 41.

[0044] After fitting the magnetic cartridge receiver flange surface 46 of the magnetic cartridge receiver 45 into the box cutout hole 34 so as to contact the box inner box 33, the box outer box 32 is attached to the outer periphery of the box inner box 33, whereby the magnetic cartridge 41 is stably attached to the stacked box body 31.

[0045] Fig. 17 is an explanatory diagram showing the cross-sectional structure of the magnetic cartridge 41 of the third embodiment of the cardboard assembly device of the present invention, Fig. 18 is a perspective view showing the structure of the members of the magnetic cartridge 41 of the third embodiment of the cardboard assembly device of the present invention before assembly, and Fig. 19 is a perspective view showing the cross-sectional structure of the magnetic cartridge 41 of the third embodiment of the cardboard assembly device of the present invention. The magnet 61 contained within the fitted interior of the magnetic cartridge cover 42 and the magnetic cartridge receiver 45 rotates inside the magnetic cartridge 41.

[0046] Although not shown, the stacked box body 31 may be configured by stacking two or more boxes.

[0047] Although the box body 11 and the stacked box body 31 have different cartridge shapes and mounting forms, both are components that assemble the device made of cardboard of the cardboard assembly device of the present invention. Therefore, although not shown, the shape of the boxes and the connection state are the same as those in Figures 1, 2, 9, and 10.

[0048] [How to use] Next, the method of using the present invention will be described. As shown in Fig. 2 and Fig. 10, the boxes 11 are connected so that the magnet cartridges 51 attached to the boxes A, large rectangular parallelepiped 21, B, medium rectangular parallelepiped 22, C, low rectangular parallelepiped column 23, D, high rectangular parallelepiped column 24, E, low right-angled isosceles triangular prism 25, F, roof 26, X, rectangular parallelepiped 27, and Y, triangular prism 28, which are examples of the shapes of the boxes 11, are abutted against each other, thereby drawing together the N pole 62 and S pole 63 of the magnet 61 to form the cardboard assembly device A1 and B2 in which the boxes 11 are connected. The cardboard assembly device A1 and B2 are only examples, and devices of various shapes can be formed depending on the shape of the boxes 11 and the combination of the boxes 11.

[0049] Although the box body 11 and the stacked box body 31 differ in the shape of the cartridge and the manner in which they are attached, both are components that assemble the device made of the corrugated cardboard of the corrugated cardboard assembly device of the present invention. Therefore, although not shown, the shape of the boxes and the state of connection are the same as in Figures 1, 2, 9, and 10, and devices of various shapes can be constructed by combining the box body 11 and the stacked box body 31.

[0050] [Manufacturing method] The box 11 of the present invention may have any configuration. An example of the box 11 is shown in a development in Fig. 13. In the development 71 of the box, mountain folds are made along lines 72 and valley folds are made along lines 73, and the overlapping outer 78 is overlapped with the overlapping inner 74 to form a rectangular parallelepiped. By inserting the insertion portion 77 into the insertion hole 76, the box 11 is formed with an inner column wall 79 that is horizontal to the inner longitudinal plane and bottom surface of the box 11. The box cutout portion 75 is formed by cutting out the portion where the magnetic cartridge 51 provided on the overlapping outer 78 overlaps with the overlapping inner 74.

[0051] Although the box body 11 and the stacked box body 31 differ in the shape of the cartridge and the manner in which they are attached, both are components that assemble the device made of corrugated cardboard of the corrugated cardboard assembly device of the present invention.

[0052] [Materials] Next, the materials and composition of the cardboard assembly device of the present invention will be described. The box body 11 and the stacked box body 31 are made of cardboard, and the magnet cartridge 51 is made of cardboard or a material derived from a chemical product, such as plastic. Various cardboards and materials derived from chemical products, such as plastics, can be used according to the purpose and use.

[0053] Corrugated cardboard is a structure in which a liner, which is a flat paper, and a medium, which is a corrugated paper, are bonded together with an adhesive. Corrugated cardboard is classified into single-sided, double-sided, and multi-sided cardboard depending on the number of liners and media, and there are various types according to the purpose of use. In addition, by imparting functions by internal and external additions at the papermaking stage, coating processing, printing processing, lamination, etc., it can be protected from dirt such as water, fire, and oil. Furthermore, it is possible to color the surface of the corrugated cardboard and write pictures and letters on it. In order to increase the strength of the entire corrugated cardboard assembly device, it is necessary to increase the strength of the box body 11 and the stacked box body 31, and for this purpose, thick A-flute cardboard, a moisture-proof liner coated with a water-proofing agent, wax-impregnated cardboard, etc. can be used.

[0054] Since cardboard is a processed product of paper made from plants, it is lighter than those made from metal or plastic, and can be used to reduce the weight of the box body 11 and stacked box body 31. In addition, when disposing of the box body 11 and stacked box body 31, material recycling and thermal recycling are possible, making it a sustainable material. The magnet cartridge 51 is made of a material derived from chemical products such as plastic, which gives it durability and allows for repeated use.

[0055] 〔effect〕 Finally, the effects of the cardboard assembly device of the present invention will be described. Since the magnet cartridge lids 52 containing the magnets 61 come into contact with each other through the box cutout holes 14 provided in the boxes 11, there is no barrier twice the thickness of the material of the boxes 11 compared to when there are no box cutout holes 14 and a container containing a magnet is attached to the box inner surface 13, and therefore the connection between the boxes 11 by magnetic force is strengthened.

[0056] By removing the magnet cartridge cover 52 from the box cutout hole 14, the magnet 61 can be replaced without destroying the box 11.

[0057] By using the box body X rectangular parallelepiped 27 and the box body Y triangular prism 28 as the box body 11, the box body cutout hole 14 needs to be provided only on the side surface of the box body 11, and the degree of freedom in connecting the box bodies 11 is increased.

[0058] As an example of the box 11, by providing an internal column wall 79 horizontally on the inner longitudinal plane and bottom surface of the box 11, deformation of the box 11 due to external pressure can be prevented.

[0059] The stacked box body 31 is formed by stacking an outer box body 32, which is sized to fit around the outer periphery of an inner box body 33 without any gaps. Therefore, the surface is made of double-layered cardboard, which increases the strength of the box body.

[0060] In addition, after the magnet cartridge 41 is fitted into the box body cutout hole 34, the box body outer box 32 is attached to the outer periphery of the box body inner box 33, so that the magnet cartridge 41 is stably attached to the stacked box body 31 without being shifted or falling off.

[0061] The shapes of the box body 11 and the stacked box body 31 are not limited to a square, triangle, rectangle, star, heart, etc., and can be various shapes in plan view. Also, the cardboard assembly device may be configured not only with the box body 11 and the stacked box body 31, but also with a panel-shaped plate body on which a magnet cartridge 51 is installed with a magnet 61 inserted for connecting.

[0062] The cardboard assembly device is composed of a box body 11, a stacked box body 31, and a plate body, which are made of cardboard. Cardboard, which is made of paper processed from plant fibers such as wood, is made of paper in a plate shape, unlike metal products or plastic products, and can be easily folded and compacted by hand. When no longer needed, it can be recycled. Since 98% of the cardboard products that are the raw material for cardboard are made from recycled paper, the recycling rate is high and it is an environmentally friendly material. On the other hand, as a result of the market being flooded with products made from plastic as a raw material worldwide, there is a strong demand for a ban on disposable plastics (one-way plastic products) and a shift from plastic materials to materials such as paper, thereby eliminating the use of plastic.

[0063] Because it uses cardboard, it is lightweight and easy to make large, reducing the risk of injury, and is recyclable and does not require disposal costs.

[0064] Because the cardboard is made from materials such as paper, it is easy to modify by drilling holes, and pencils, water-based pens, and paints can be used.

[0065] The box body 11, the stacked box body 31 and the plate body can be given various textures and images by changing the thickness, material and surface treatment. Specifically, this is done by selecting the material, adding a color, pattern or design to the surface, special coating, lamination, etc. Depending on the condition of the surface, it is possible to freely add creativity by writing graffiti on the surface, attaching a wide variety of items such as replaceable sheets and accessories, etc. Also, by mixing into the material or coating the surface, it is possible to make them waterproof, stain-proof and fire-resistant, which increases the ease of maintenance and safety.

[0066] The strength of the box body 11, stacked box body 31 and plate body that make up the cardboard assembly device can be increased by selecting and configuring the materials, which ensures stability and safety, and allows the cardboard assembly device to become a large structure using many box bodies 11 and plate bodies.

[0067] The boxes 11 and the stacked boxes 31 can be tightly connected by the magnets 61 attracting each other with their respective north poles 62 and south poles 63, thereby forming a cardboard assembly device that spans a vertical and horizontal space. Furthermore, multiple cardboard assembly devices can be combined to build a structure with a large space.

[0068] By using magnets 61 as connectors for parts that make up a structure, box body 11 and stacked box body 31 can be easily connected to each other, and by adjusting the magnetic force, the stability of the connection can be increased or otherwise adjusted as desired.

[0069] To change the size, the height and length of the box body 11, the stacked box body 31, and the plate body can be easily added, and the connection with the magnet 61 provides a sense of stability.

[0070] Because the box body 11, the stacked box body 31, and the plate body can be separated from each other in the cardboard assembly device, the box body 11, the stacked box body 31, and the plate body can be combined and stored compactly after use as the cardboard assembly device. The box body 11 and the stacked box body 31 can be combined to leave the cardboard assembly device in a state with no internal space.

[0071] It is expected that a wide range of users, from children to adults, can play with it alone or in groups, according to their own needs, while increasing their intelligence by using their creativity like a puzzle to build a cardboard assembly device, which is a structure.

[0072] By playing with a cardboard assembly device, which is a large structure, parents and children can deepen their relationship through physical contact and can also increase their creativity and sense of happiness.

[0073] Depending on the size of the structure, the cardboard assembly equipment can be used as a secret base for children to play in, a house for making toys, a secret space, a cardboard teahouse that embodies Japanese culture, a cardboard maze or amusement park filled with fun, or an event space.

[0074] As described above, 1. By using magnets 61 as connectors for the box body 11, stacked box body 31, and plate body that constitute the cardboard assembly device, the box body 11 and the stacked box body 31 can be easily connected to each other, and the strength and stability of the connection and coupling can be adjusted as desired by adjusting the magnetic force. 2. In order to change the size, the box body 11, stacked box body 31, and plate body that can be adjusted in height and length are added, and the connection by magnets 61 provides a sense of stability. 3. Since the box body 11 and stacked box body 31 are made of cardboard, they are lightweight and can be easily made large, reducing the risk of injury, and they can be recycled and no disposal costs are required. 4. Since the box body 11 and stacked box body 31 are made of cardboard, modifications such as drilling holes are easy, and pencils, water-based pens, and paints can be used. [Industrial Applicability]

[0075] To provide a cardboard assembly device that uses ecological materials, meets various needs from adults to children, from personal use to social use, has a soothing soft paper feel, and is easy to store. [Explanation of symbols]
