Description

[Technical Field]

[0001] The present invention relates to a technique for installing a temporary magnetic wall by combining partition plates, and particularly to the installation of a temporary magnetic wall having corners. [Background technology]

[0002] In the past, when constructing temporary walls, it was common to create them by combining existing partitions. In this case, the legs that allowed the partitions to stand on their own got in the way, and when creating corners, simply combining linear partitions left gaps in the corners, causing layout problems. In addition, since the surfaces of many existing partitions are made of non-magnetic material, it was necessary to attach a separate magnetic material to the surface in order to create a magnetic wall.

[0003] On the other hand, instead of using ready-made partitions, it is also possible to use the permanent wall panels described in Patent Document 1 below. The surface of this panel is covered with a metal plate, so it has the properties of a magnetic wall surface. In addition, there are convex and concave portions, which can be fitted together to connect in a straight line without gaps. However, because it is not intended to be used as a temporary wall, the edges have exposed convex and concave parts, which make it look unattractive and require additional decorative treatment. Also, for example, if it is L-shaped, the corners cannot be connected using the above-mentioned method, so it is necessary to fasten them with screws using separate mounting hardware, which makes installation and disassembly complicated.

[0004] [Patent Document 1] Patent Publication No. 2015-145690 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0005] In recent years, the SDGs have been gaining attention, and there has been a growing trend to recycle and reuse goods in order to reduce waste. The same is true for temporary walls, and attention is now being paid to reusable walls, such as booth dividers and signage boards used at exhibitions. Furthermore, when disasters such as typhoons and earthquakes occur, evacuation shelters may be set up, and temporary walls will be needed to separate each evacuee family. If the evacuation is prolonged, temporary housing and stores will also need to be set up, and it is desirable that these be constructed with reusable walls.

[0006] These systems must be easily and quickly installed, and must also be installed without gaps at wall joints or corners. In particular, in evacuation shelters, it is strongly required to have no gaps from the perspective of privacy. Furthermore, since the space available for installing temporary walls is often limited, it is necessary to make effective use of the space. If the temporary walls are made magnetic, magnetic fixtures can be easily attached and detached to any desired location, allowing for effective use of the limited space.

[0007] The present invention has been made with the above-mentioned circumstances in mind, and its object is to provide a reusable temporary magnetic wall surface that can be installed quickly and easily, does not create gaps even at the joints and corners of the wall surface, and can be dismantled quickly and easily. [Means for solving the problem]

[0008] The present invention takes the following measures to solve the above problems.

[0009] A joint according to one aspect of the present invention is a joint for forming a corner portion on a temporary wall surface formed by connecting a plurality of partition plates, wherein the partition plates have a partition plate convex portion at one end and a partition plate concave portion at the other end, the partition plate convex portion has protrusions on both sides, and the partition plate concave portion has protrusions on both inner faces, and the joint has two protrusions at two locations, a first location and a second location on the same side, spaced apart so that the protrusions of the partition plate convex portions can be sandwiched between them, and when connecting partition plates at a straight portion of the temporary wall surface, the other partition plate convex portion is inserted into the partition plate concave portion and fitted together. By doing so, the partition plates are connected in a straight line, and when connecting the partition plates at the corners of the temporary wall surface, a corner is formed by abutting only the corners of the convex parts of multiple partition plates, and at the formed corner, the protrusions of the convex parts of the first partition plate are sandwiched between the two protrusions at the first location of the joint and, at the same time, the protrusions of the convex parts of the second partition plate are sandwiched between the two protrusions at the second location of the same joint, and the joint is attached in this manner, which is repeated for the protrusions of all the partition plate convex parts, thereby connecting the multiple partition plates.

[0010] In another embodiment of the joint of the present invention, a joint to be attached to the inside corner side of a corner has a protrusion on the surface on the outside corner side of the corner, and a joint to be attached to the outside corner side of the corner has a protrusion on the surface on the inside corner side of the corner.

[0011] In a joint according to another aspect of the present invention, the protrusions of the joint are magnets.

[0012] The temporary wall surface according to another aspect of the present invention has at least one corner formed by a joint.

[0013] In another embodiment of the temporary wall of the present invention, the surfaces of the partition plates and the surfaces of the joints are made of soft magnetic material.

[0014] In another embodiment of the temporary wall surface of the present invention, end decorative panels are inserted into recesses in the partition panels that form the ends of the temporary wall surface.

[0015] In another aspect of the temporary wall of the present invention, when two partition plates are connected by inverting them with their recesses butted against each other, a reverse plate is sandwiched between the recesses. [Effects of the Invention]

[0016] According to the present invention, a reusable temporary magnetic wall surface can be provided which can be installed quickly and easily without tools, without creating gaps even at joints and corners of the wall surface, and which can be dismantled quickly and easily.

DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. Note that the scale and angles of components and the like shown in the accompanying drawings do not necessarily correspond to the actual objects, but have been adjusted to a size that is easy to understand. In particular, for the sake of convenience, the height direction of each drawing in this application is significantly reduced.

[0019] [Divider board] FIG. 1 shows a partition board 10 used in a temporary wall according to the present invention. The partition board 10 is a Styrowall UE (registered trademark) manufactured by Styro Kako Co., Ltd., and has a core material 11 covered by a surface material 12, with convex portions 13 and concave portions 14. The core material 11 is made of polyisocyanurate foam, a plastic foam. The surface material 12 is made of steel plate, a soft magnetic material, and is capable of magnetically attracting hard magnetic materials, i.e., magnets. The convex portions 13 have protrusions 15 on both sides. The concave portions 14 have protrusions 16 on both inner surfaces. As shown in FIG. 2, the convex projections 15 of the partition plates 10 engage with the concave projections 16, so that the partition plates 10 can be fitted together linearly without any gaps.

[0020] [Comparative Example] To clarify the present invention, a conventional installation example using the above-mentioned partition board will first be described as a comparative example with reference to Figures 18 to 20. This comparative example relates to the installation of an L-shaped signage board, which is a type of temporary wall surface and is used at exhibitions and the like. The L-shape is adopted for many signage boards because it allows for stable, self-standing installation.

[0021] First, as shown in Figure 18, two U-shaped guide rails 120 are prepared and fixed to the floor surface so that one guide rail 120A and the other guide rail 120B are at a right angle. At this time, the tip of guide rail 120A and the side surface 121B of guide rail 120B are abutted against each other so that they are flush with each other. For fixing, hook-and-loop fasteners or double-sided tape are used depending on the material of the floor surface.

[0022] Next, as shown in Fig. 19, partition boards 10 are placed on guide rails 120A and 120B, respectively. At this time, the partition board 10 is placed so that the recessed portion 14 of the partition board 10 placed on guide rail 120B faces the side surface of the partition board 10 placed on guide rail 120A. By doing so, the displayable area and shape of the signage board become the most efficient in this comparative example. The side surface 121A hatched in FIG. 19 is wedged between the two partition plates 10, and therefore a gap is created between the two partition plates 10 by the thickness of the side surface 121A. Furthermore, the partition board 10 placed on the guide rail 120A will bite into the partition board 10 placed on the guide rail 120B by the thickness of the partition board 10. This results in a so-called win-lose situation, and the partition board 10 placed on the guide rail 120A will have a shorter effective width than the partition board 10 placed on the guide rail 120B, resulting in the signage board becoming asymmetrical.

[0023] Fig. 20 shows the completed form of the signage board 100. Fig. 20(a) is a view of the signage board 100 seen from the inside corner side, and Fig. 20(b) is a view of the signage board 100 seen from the outside corner side. Guide rails 120 are placed on each partition board 10, and the two partition boards 10 are connected at the corners by fastening them with screws 141 via mounting brackets 131. The boards are connected at five points in total: two points at the top and bottom of the inside corner, two points at the top and bottom of the outside corner, and one point at the top. This allows the signage board 100 to stand stably on its own.

[0024] The convex portions 13 and concave portions 14 are exposed at both ends of the signage board 100, and the convex portions 13 are exposed at the corners of the corners. This does not look good, so it is necessary to apply a decorative treatment with tape or the like, but this part cannot be used as a magnetic wall surface. Furthermore, as mentioned above, a gap equal to the thickness of the guide rail is created between the two partition boards 10 at the corners. In addition, since the partition boards 10 are not aligned, the left and right become asymmetrical, which is undesirable in terms of layout and design of the notices. Furthermore, screws are required to ensure stability and self-standing, making installation more complicated. The screws are fastened at the bottom and top of the signage board 100, so the work at the bottom requires crawling on the floor. Also, some signage boards are over 2m high, so fastening the screws at the top requires climbing a ladder and working at a high altitude, which can be dangerous.

[0025] An embodiment of the present invention that overcomes these disadvantages will be described below.

[0026] [First embodiment] A first embodiment of the present invention is shown in Figures 3 to 13. In this embodiment, as in the comparative example described above, the installation of an L-shaped signage board, which is a type of temporary wall surface, will be described.

[0027] [Guide rail] FIG. 3 shows the guide rail 20 used in this embodiment. The guide rail 20 is U-shaped and fixed to the floor surface, on which the partition board 10 is placed. In addition, by placing this product on top of the placed partition board 10, a decorative finish is applied to the top of the partition board 10. The guide rail in this figure is used to form a corner, and one end is cut off at a 45-degree angle. The cut-off directions of guide rails 21A and 21B are opposite, and by abutting the cut-off portions of each other, they can be connected at a 90-degree angle. The guide rails are made of metal plate, resin, etc. Each guide rail shown in this diagram is divided into two parts to facilitate manufacturing, but the shape and number of parts are not important as long as the desired L-shape can be achieved. For example, it can be a single part. Also, although the diagram shows a 90-degree angle, it is not limited to this and can be any angle, such as 60 degrees or 120 degrees.

[0028] [Fitting] Figure 4 shows the joints that are attached to the partition board. The joint is used to connect multiple partition panels at corners and also to apply decorative treatment to the corners. The joint also has two protrusions on the same surface to sandwich the protrusions of the partition panels. The first joint 30 in Figure 4(a) is an L-shaped steel plate 31, which has two linear protrusions 32 at two locations on the inside corner side. The two protrusions 32 on the same plane are spaced apart so that they can sandwich the convex protrusions 15 of the partition plate 10. The first joint 30 is attached to the outside corner side of the corner. The steel plate 31 is a soft magnetic material. The second joint 40 in Figure 4(b) is an L-shaped steel plate 41, and has two linear protrusions 42 at two locations on the outside corner side. The two protrusions 32 on the same plane are spaced apart so that they can sandwich the convex protrusions 15 of the partition plate 10. The first joint 40 is attached to the inside corner side of the corner. The steel plate 41 is a soft magnetic material. The first joint protrusion 32 and the second joint protrusion 42 may be integral with the first joint steel plate 31 and the second joint steel plate 41, respectively, or may be attached as separate members. If they are separate members, they may be made of the same material as the steel plate, or a different material such as resin. If the first joint protrusion 32 and the second joint protrusion 42 are made into magnetic sheets cut into a straight line, the partition plate 10 can also be magnetically attached.

[0029] [End decorative panel] FIG. 13(a) shows the end decorative panel used in this embodiment. The end decorative panel 60 is a steel plate 61 processed into a U-shape, and is sized to be able to be inserted into the recess 14 of the partition plate 10. The steel plate 61 is a soft magnetic material. By inserting the end decorative panel 60 into the recess 14 of the partition board 10, the end of the partition board 10 can be decorated. In addition, a magnetic notice, which will be described later, can be sandwiched between the recess 14 and the magnetic holder itself.

[0030] [Signage board] The installation of the signage board of this embodiment will be described below. First, as shown in Figure 7, guide rails 21A and 21B are fixed to the floor surface, with their notched surfaces abutting against each other to form a right angle. Fixing to the floor surface is done using hook-and-loop fasteners or double-sided tape depending on the floor material.

[0031] Next, the partition boards 10 are placed on the guide rails 21A and 21B, respectively, as shown in Fig. 8. If the partition boards 10 are placed so that only the corners of the protrusions 13 of each partition board 10 abut, the signage board will be symmetrical and can be connected using the first and second joints described below.

[0032] Next, as shown in Figure 9, the first joint 30 is inserted into the guide rails 21A and 21B while the first joint protrusion 32 holds the convex protrusion 15 of the partition board 10 at the outside corner side of the corner. Similarly, the second joint 40 is inserted into the guide rails 21A and 21B while the second joint protrusion 42 holds the convex protrusion 15 of the partition board 10 at the inside corner side of the corner. Also, end decorative panels 60 are inserted into the recesses 14 of the partition board 10 at both ends.

[0033] An enlarged view of the corner is shown in Figure 10. In this figure, the partition board 10 is hatched. Two first joint protrusions 32 on the same surface on the inside corner side of the first joint 30 sandwich the partition plate protrusion 15 on the outside corner side of the partition plate 10. Similarly, two second joint protrusions 42 on the same surface on the outside corner side of the second joint 40 sandwich the partition plate protrusion 15 on the inside corner side of the partition plate 10. These fitting forces connect the two partition boards 10 via the first joint 30 and the second joint 40. Connecting the partition boards 10 in an L-shape allows the signage board to stand stably on its own. In this embodiment, the first joint protrusion 32 and the second joint protrusion 42 are made of a linearly cut magnetic sheet. By using a magnetic sheet, a magnetic force acts in addition to a fitting force between the partition plate 10 and the first joint 30 and the second joint 40, so that it is possible to resist stress in all directions and to connect the partition plate 10 more firmly and stably. By attaching the first joint 30 and the second joint 40, the surface of the partition board 10 and the surfaces of each joint become flush with each other without any gaps, allowing them to be used as a single wall surface. Also, by abutting only the corners of the protruding portions 13 of the two partition boards 10, the completed signage board can be made symmetrical. On the other hand, the first joint conceals the space D that would otherwise be created by abutting only the corners, in other words, it also provides a decorative treatment. Space D can be used to pass power or communication cables, as needed.

[0034] 11 shows an enlarged view of the end portion, in which the partition plate 10 is hatched. The decorative treatment of the end portion is completed simply by inserting the end decorative panel 60 into the recess 14 of the partition board 10. This allows the end portion of the partition board 10 to be used as a wall surface. In addition, a magnetic notice, which will be described later, can be sandwiched between itself and the recess 14. Due to design and layout considerations, excess notice material may be generated, but by sandwiching it, the excess material can be absorbed. In this case, the notice can be rolled up and stored in the space D created between the recess 14. Conversely, when needed, it can be pulled out and used. In other words, flexible design and layout are possible without being limited by the size or shape of the notice material.

[0035] Figure 12 shows the completed signage board 1. The signage board 1 of this embodiment is completed by placing the guide rails 21A and 21B on the top of the partition board 10. Figure 12(a) is a view of the signage board 1 from the inside corner side, and Figure 12(b) is a view from the outside corner side.

[0036] An example of how the signage board 1 of this embodiment is used is shown in FIG. The wall surface of the signage board 1 is a magnetic wall surface made of a soft magnetic material. For this reason, if a magnetic sheet printing medium, such as Magnemedia (registered trademark) manufactured by Nichirei Magnet Corporation, which can be printed on with an inkjet printer, is used, a magnetic notice 81 can be magnetically attached to the signage board 1. It is also possible to magnetically attach magnetic fixtures 82 with a magnetic sheet attached to the backside. In this drawing, notices and fixtures are magnetically attached to the wall surface on the inside corner of the signage board 1 and on the side surfaces at both ends, but it is also possible to magnetically attach notices and fixtures to the wall surface on the outside corner. Magnetically attached notices and fixtures can be easily attached and detached, making it easy to change them for each event, for example.

[0037] In this embodiment, a signage board that is stable and freestanding can be provided without the need for the mounting hardware and screws that were previously required for installation, i.e., without the use of any tools. This is because the first joint and the second joint perform the same functions as the mounting hardware and screws that were previously required to connect the partition boards. Furthermore, there are no gaps at the corners, and there is no need to apply separate decorative treatment to the corners and both ends, as was previously necessary, making it possible to provide a signage board that is flush with the entire wall surface and symmetrical on both sides.This is because the first and second joints also serve as decorative treatments. In addition, any excess material that arises due to design or layout can be absorbed by being sandwiched and rolled up between the end decorative panel and the recessed part of the partition board, and conversely, can be pulled out when needed, providing a user-friendly signage board that allows for flexible design and layout. In other words, it is possible to provide a user-friendly signage board that can be quickly and easily set up and dismantled without tools, can maximize the wall surface area, and can utilize the entire area as a magnetic wall, and has excellent layout and design properties for posted materials. In this embodiment, the signage board is made up of two partition boards, but it can also be made up of three or more partition boards. The signage board described in this embodiment is a type of temporary wall surface, and therefore this embodiment can be widely applied to temporary wall surfaces other than signage boards.

[0038] [Second embodiment] A second embodiment of the present invention will now be described. So far, we have explained an L-shaped signage board, but it may also be T-shaped or X-shaped. Figure 6 shows guide rails used for the T-shaped and X-shaped signage boards used in this embodiment. FIG. 6(a) shows a guide rail for a T-shape, in which 22A and 22B are used in combination. FIG. 6(b) shows a guide rail for an X-shape, in which four guide rails 23 of the same shape are combined together for use. Each guide rail shown in this diagram is divided into parts to facilitate manufacturing, but as long as the desired T-shape or X-shape can be achieved, the shape and number of parts are not important. For example, it can be a single part.

[0039] FIG. 4(c) shows a third joint 50 for a T-shape. When forming a T-shape, the three partition plates 10 are arranged so that only the corners of the protruding portions 13 are in contact with each other. Joints 40 are attached to the two inside corners, and a third joint 50 is attached to the straight portion opposite them. The third joint 50 is a flat steel plate 51, and has two linear protrusions 52 at each end. The two protrusions 52 at the ends are spaced apart enough to sandwich the convex protrusions 15 of the partition plate 10. The steel plate 31 is a soft magnetic material. The third joint protrusion 52 may be integral with the steel plate 51, or may be attached as a separate member. If it is a separate member, it may be made of the same material as the steel plate, or a different material such as resin. If the third joint protrusion 52 is made of a linearly cut magnetic sheet, it can magnetically attach the partition plate 10, thereby resisting stress in all directions and connecting the partition plates 10 more firmly.

[0040] In the case of a T-shape, as shown in Figure 14, T-shaped guide rails 22A and 22B are fixed to the floor surface and three partition boards 10 are placed on top of them. The three partition boards 10 are placed so that only the corners of their respective convex portions 13 abut. Then, second joints 40 are attached to the two inside corners of the T-shape and third joints 50 are attached to the opposing straight portions. End decorative panels 60 are attached to the three ends, and the guide rails 22A and 22B are placed on the tops of the partition boards, completing the T-shaped signage board 2.

[0041] In the case of an X-shape, as shown in Figure 15, four guide rails 23 for the X-shape are fixed to the floor surface and four partition boards 10 are placed on top of them. The four partition boards 10 are placed so that only the corners of their respective protrusions 13 abut. Then, second joints 40 are attached to the four inside corners of the X-shape. End decorative panels 60 are attached to the four ends, and the four guide rails 23 are placed on the tops of the partition boards, completing the X-shaped signage board 3.

[0042] [Third embodiment] So far, various shapes of signage boards have been described, but as a third embodiment, a temporary wall surface that combines various shapes will be described. As mentioned above, at corners, it is necessary to abut only the corners of the convex parts of each of the partition panels. If this is left as is, the edges that are not corners will inevitably become concave, and corners cannot be formed. Therefore, if the direction of the partition board that forms the straight section is reversed midway, that is, if the convex and concave sections are changed from being connected to each other so that the concave sections abut each other, both ends will become convex and it will be possible to form corners. However, because the concave sections are only abutting each other, there is no way to resist the shear stress, i.e., the force in the short direction of the partition board, and there is a risk that the partition board will shift in that area or, in the worst case, collapse. Therefore, a reverse plate 70 shown in Figure 6(b) is used. The reverse plate 70 is made by processing a plate material 71 into a U-shape. As shown in Figure 16, the reverse plate 70 is sandwiched between partition plates 10 with the recessed portions 14 abutting against it. Because the partition plate is reversed at this point, it becomes possible to form corners at both ends. Furthermore, the presence of the reverse plate 70 between the partition plates makes it possible to withstand shear stress, increasing the strength of the temporary wall surface and improving safety.

[0043] By reversing the partition board, it becomes possible to set up a temporary wall 4 as shown in Figure 17. Even with such a wall, no tools or additional decorative treatments are required for installation. Because it can be set up quickly and easily, it can be used in a variety of temporary facilities, including evacuation shelters, temporary housing, and temporary stores in the event of a disaster.

[0044] Although the embodiments of the present invention have been described above, the embodiments disclosed above are merely examples, and the scope of the present invention is not limited to these embodiments. The scope of the present invention is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims. [Explanation of symbols]
