Description

The present invention relates to a magnetic wall in which a magnet sheet is attached to a wall substrate as an adherend of the magnet sheet, and a magnetic display mechanism using the same.
More specifically, the wall surface of which the magnet sheet subjected to multi-pole magnetism is attached to the wall substrate as the adherend of the magnet is combined with the magnet sheet subjected to multi-pole magnetization between the magnet sheet and the same pole. The surface material, display material, or article holding material (shelf, etc.) can be aligned and attached in the magnetic pole direction of the magnet sheet of the adherend by different pole attraction and isopolar repulsion with the magnet sheet of the adherend. It relates to a magnetic wall and a magnetic display mechanism.

A display piece using a magnet sheet subjected to multi-pole magnetization between the magnet sheet and the same pole is attached to an adherend to which a magnet sheet subjected to multi-pole magnetization is attached as a magnet adherend. The following two cases are disclosed as display techniques that enable alignment and attachment of a magnet sheet, which is an adherend, in the magnetic pole direction by attraction and isopolar repulsion.

Utility Model Bulletin Showa 63-15902 JP-A-6-27895

A display piece using a conventional magnet sheet subjected to multi-pole magnetization between the magnet sheet and the same pole is attached to an adherend to which a magnet sheet subjected to multi-pole magnetization is attached as a magnet adherend. The display board, which has the ability to align and attach in the magnetic pole direction of the magnet sheet, which is the adherend, by the attraction of different poles and the same pole repulsion, was used in the size of a small bulletin board, but recently it has been used on the entire wall surface. It has been expanded to use in a wide area.

In order to accommodate a large area, it is necessary to attach the magnet sheet in a spliced manner. For example, when using it in an area of 3m x 3m on the wall surface, the magnetic pole direction of the multi-pole magnetization of a normal magnet sheet is rolled. In the molding or extrusion molding, the machine direction, that is, the vertical direction which is the flow direction of the original fabric of the magnet sheet << hereinafter referred to as "the vertical direction of the magnet sheet" >> is magnetized, and the horizontal direction with respect to the vertical direction. Some of them are magnetized in the "horizontal direction of the magnet sheet", and the magnetic pole direction is magnetized in the vertical direction of the magnet sheet. The horizontal direction of the magnet sheet is 1 m x magnet. A method of attaching three sheets in the vertical direction of the sheet in the vertical direction of the wall surface with the magnetic pole direction of the sheet attached to the wall surface in the horizontal direction of the wall surface [Fig. 1], and the magnetic pole direction in the horizontal direction of the magnet sheet. There is a method (FIG. 2) in which three magnetized magnet sheets are spliced together in the horizontal direction of the wall surface by using the vertical direction of the magnet sheet in the vertical direction of the wall surface.

In the case of the former [Fig. 1], magnetic repulsion or change in the distance between magnetic poles is caused by magnetic pole splitting due to cutting at the middle reliever, so it is difficult to attach without a gap at the middle reliever attachment point, or the middle reliever is attached. There is an inconvenience that the affixed part causes a middle reliever over time. In addition, since the same magnetic pole arrangement and magnetic pole spacing as in the non-middle reliever portion cannot be obtained, the poles of the magnet sheet of the adherend and the magnet sheet attached to the surface cannot be matched with each other, resulting in a decrease in magnetic attraction or magnetism. There is an inconvenience that causes repulsion and causes peeling to floating.

In the case of the latter [Fig. 2] mentioned above, in order to make the same pole continuously for 3 m, it is necessary to make a middle reliever between the same poles at the middle reliever, and it is difficult to attach without a gap at the middle reliever due to the reliever of the same pole. , There is an inconvenience that the middle reliever attachment point causes a gap over time. In addition, there is an inconvenience that it is difficult to achieve continuous equivalence for 3 m because magnetic adsorption may occur with a one-pole width shift due to heteropolar suction and homopolar repulsion.

Recently, it has been desired to develop a magnetic wall and a magnetic display mechanism capable of horizontally aligning display pieces and the like over the entire surface of the wall without causing inconvenience due to the sticking of the middle reliever.
An object of the present invention is to solve the above-mentioned inconveniences and demands.

As a result of diligent studies to solve the above-mentioned problems, as a countermeasure against the inconvenience of FIG. 2, a magnet sheet magnetized with the magnetic pole direction in the lateral direction of the magnet sheet is attached to the magnetic pole direction in the horizontal direction of the wall surface. When attaching the relay in the horizontal direction, magnetize the ends of one or both of the facing magnet sheets so that magnetic poles are not provided, or apply a magnetic field in the thickness direction to apply the magnetic pole ends of multi-pole magnetization. After erasing, they have found that the main problem can be solved by aligning the center lines of the magnetic poles so that the center lines of the magnetic poles of the same pole before and after the relay are aligned and sticking them together, and have achieved the present invention.

Then, the upper end magnetic pole and the lower end magnetic pole of the magnet sheet in which the surface decorative material, the display material, or the article holding material is combined are set to the same pole or different poles, and the magnet sheet is cut on the boundary line between the N pole and the S pole.

If the back surface of the magnetic sheet of the magnetic wall has a ferromagnetic layer, magnetically attach a composite magnet sheet (magnetic shelf, etc.) that has the ferromagnetic layer on the back surface of the magnet sheet to form a magnetically closed circuit. By forming and using a foam-based pressure-sensitive adhesive (adhesive), the formation of an air gap on the magnetically attached surface is prevented and a large magnetic attraction force is obtained, and further, the magnetization of the article holding material composite magnet sheet is performed. By providing the anti-slip layer on the surface, the shearing tensile magnetic attraction force increases and excellent load bearing capacity can be obtained.

Hereinafter, embodiments for carrying out the present invention will be described with reference to FIGS. 2 to 13.
≪About magnetic wall≫
(1) FIG. 2 shows, as an example of a magnet sheet in which the magnetic pole direction is magnetized in the lateral direction of the magnet sheet, a magnetic pole of 1 m in the horizontal direction of the magnet sheet × 3 m in the vertical direction of the magnet sheet is attached to the wall surface. There is a schematic diagram showing the inconvenience when three sheets are bonded in the horizontal direction of the wall surface, and the same pole repulsion occurs in the first and second sheets from the right. In addition, since the second and third pieces from the right are magnetically attracted with a one-pole width shift due to the attraction of different poles and the same pole repulsion, the center of the same pole of multi-pole magnetization between continuous same poles. It is a conceptual schematic diagram (side view) showing that the inconvenience of not being able to attach the joints to each other occurs.

In order to solve the inconvenience as shown in FIG. 2, in order to demagnetize one of the multi-pole magnetized ends of at least one of the magnet sheets facing each other in the joint attachment, or to eliminate the magnetic poles. The magnet sheet is demagnetized by applying a decaying alternating magnetic field from a magnetic field of the magnet sheet's intrinsic coercive force (iHc) or more, or a magnetic field of about 1.2 or more of the intrinsic coercive force (iHc) of the magnet sheet is applied in the thickness direction. By eliminating the end magnetic poles, it is necessary to prevent practical inconvenience, but practical inconvenience is caused by applying a magnetic field of about 1.2 or more of the intrinsic holding magnetic force (iHc) of the magnet sheet in the vertical direction. It is easy and economical to make it so that it does not occur. FIG. 3 is a conceptual diagram (perspective view) showing an example thereof, and may be a magnetic field of upper and lower NS or upper and lower SN. When erasing both end magnetic poles, if one is upper and lower NS, the other is preferably the upper and lower SN magnetic fields.

FIG. 4 shows an example in which an untreated magnet sheet is affixed and attached to the left side of the figure in which the magnetic poles of the multi-pole magnetism are erased as in FIG. The erasing width of the magnetic poles of the multi-pole magnetization is preferably in the range of 0.8 to 1.5 times the length between the poles of the multi-pole magnetization, and 0.8 times the distance between the poles of the multi-pole magnetization. If it is smaller, the effect may be insufficient, and if it exceeds 1.5 times the magnetic pole width, it cannot be ignored as a continuous magnetic pole defect in some cases.

If the magnetic poles of the multi-pole magnetization are insufficiently erased, a magnetic field in the same direction may be applied in the same direction from the opposite surface treated earlier, and the magnetic fields in the same direction may be applied simultaneously from both the upper and lower surfaces. May be. Further, if the erasing magnet is provided with a non-magnetic guide for specifying the erasing width so that the erasing width of the multi-pole magnetized magnetic poles does not vary, the work can be easily performed. (Fig. 3)

FIG. 5A shows a magnet sheet between the magnet sheet used for the magnetic wall and the same pole in order to align the center lines of the magnetic poles of the same polarity shown in FIG. 4 and obtain excellent attachment accuracy. As a "magnetic pole ruler", it is shown that the center lines of the same magnetic poles of both magnet sheets to be joined are aligned and magnetically attached by using the underlay of both magnet sheets to be joined by different pole attraction and same pole repulsion. Reference numeral 5 (b) indicates that both ends of the magnet sheet are rolled up to remove the magnetic pole ruler after the entire surface is attached. In this way, as shown in FIG. 5A, by aligning the center lines of the poles of the same polarity of the magnet sheet to be attached to the middle reliever, the inconvenience of the attachment of the middle reliever is solved and the magnet sheet of the magnetic wall is covered over the entire magnetic wall. A magnet sheet that has been magnetized with multiple poles between the same poles can be magnetically attached.
Then, when the magnet sheet is attached to the substrate of the magnetic wall using a double-sided pressure-sensitive adhesive, the center line of the magnetic poles is aligned and a part of the magnet sheet is attached. It is advisable to make a cut in the release paper of the part to be attached after removing the "magnetic pole ruler".

Further, as another method for aligning the center lines of magnetic poles of the same polarity and obtaining excellent attachment accuracy, as shown in [Fig. 9], the ends of both magnet sheets to be attached to the middle reliever are attracted to the same electrode. Magnetically affixed on top of each other by repulsion, cut off the overlapping substantially central part, roll up one cut part and end part to the required range to remove the other cut part, and one or both of the facing magnet sheets. There is a method of erasing the magnetic poles of the end portion of the above in the same manner as in the above [FIG. 3], and then abutting and magnetically attaching the ends.
Then, when the magnet sheet is attached to the substrate of the magnetic wall using a double-sided pressure-sensitive adhesive, the center line of the magnetic poles is aligned with the part where a part of the magnet sheet is attached, and the magnet sheet is turned up and cut off. It is advisable to make a cut in the release paper of the part to be attached after removing the part.

≪About magnetic display mechanism≫
A magnetic display piece or a composite magnet sheet in which a surface material, a display material, an article holding material (shelf, etc.), etc. are bonded to the back surface of a magnet sheet that has been magnetized with multiple poles between the magnet sheet of the magnetic wall and the same pole. When multiple magnetic shelves are used and magnetically attached close to the magnetic wall, the magnetic repulsion caused by facing each other with the same polarity according to the cutting specifications of the magnetic display piece and the magnetic repulsion between one magnetic display piece and the magnetic wall In the case of cutting in which the magnetic pole ends are narrow even if they face each other with different poles, there is a problem that magnetic sticking cannot be performed without a gap between the adjacent magnetic display pieces.

Explaining the magnetic display piece that can be magnetically attached to the magnetic display mechanism of the present invention, FIG. 7B shows a graph (schematic diagram) of the surface magnetic flux density of the magnetized surface of the magnet sheet, and shows the magnetic poles of the magnetic poles. Focusing on the fact that the boundary point has a magnetic flux density of 0, the north and south poles as shown in the image of the magnetic viewer sheet MB (microcapsules of magnetic fluid uniformly distributed on the film) shown in FIG. 7 (a). Focusing on the fact that magnetic repulsion does not occur practically if the magnetism is cut at the boundary line bl of The magnetic display piece of the present invention is obtained by sticking a piece cut with bl by abutting as shown in FIG.

The surface magnetic flux density is shown in the schematic diagram of the graph waveform of the surface magnetic flux density of the magnetized surface in the single-sided magnetized product. As a result, the graph on the back surface of one surface is a graph in which the north pole and the south pole are interchanged. In addition, even in the case of a single-sided magnetized product between poles that is approximately twice or more the thickness, the non-magnetized surface is slightly weak, but the graph is such that the north and south poles of the graph are interchanged, as in the case of double-sided magnetization. Also, the magnetic flux density at the boundary point between the N pole and the S pole becomes 0.

FIG. 9 is a conceptual schematic diagram (side view) showing another method for cutting on the boundary line between the north pole and the south pole of the present invention, and FIG. 9A is an end portion of both magnet sheets. 9 (b) and 9 (c) are diagrams of FIG. 9 (a), which are conceptual schematic views (side views) showing cutting on the magnetic pole boundary line in a superposed state due to attraction and repulsion of different poles. It is a partially enlarged view showing that a and d are abutted after cutting except for b and c, and FIG. 9 (d) shows a state in which the a and d are abutted and attached.

It should be noted that the polarities of the opposing magnetic poles are different and are cut on the boundary line between the N pole and the S pole, or further cut on the magnetic pole boundary line in a superposed state by suction and same pole repulsion of different poles. The technique for middle reliever attachment, which is characterized by the above, can also be used when the magnet sheet of the magnetic wall is attached to the middle reliever in the vertical direction.

FIG. 10 is a conceptual schematic diagram showing an example of the magnetic display mechanism of the present invention.
FIG. 10A shows a magnet sheet in which a surface material is laminated on a magnet sheet in which the magnetic pole direction is the lateral direction of the magnet sheet and multi-pole magnetization between the same poles is applied to one side as a magnetic wall to be an adherend of the magnet.

After erasing the magnetic pole ends of multi-pole magnetization by applying a magnetic field of about 1.2 of the intrinsic coercive force of the magnet sheet, the magnetic poles of the same magnetic polarity before and after the relay are abutted and attached so that the centers of the magnetic poles match. On the magnetic wall,

FIG. 11 shows a magnetic shelf made of an L-shaped shelf LR, which is an article holding material, an anti-slip layer 9, a magnet sheet 1 subjected to multi-pole magnetization, a ferromagnetic layer 8, and a pressure-sensitive adhesive 62 whose base material is a foam. It is a conceptual schematic diagram (left side view) showing one example of.
The anti-slip layer 9 increases the static frictional force in the in-plane direction of the magnetic shelf magnetically attracted to the magnetic wall, and the ferromagnetic layer 8 attached to the back surface of the multi-pole magnetized magnet sheet 1 makes the magnet sheet. By preventing the back leakage magnetic flux of 1 and using the pressure-sensitive adhesive material 62 whose base material is a foam foam,
The base material is a foam that creates an air gap (thickness or distance between the magnet and the magnet's adherend, the non-magnetic material or space) between the inflexible magnetic wall and the inflexible magnetic shelf. The effect of increasing the load capacity of the magnetic shelf is obtained by the three effects of alleviating the deformation of the foam of the pressure-sensitive adhesive material 62.

FIG. 12A is a conceptual schematic diagram (side view) showing an example of the magnetic display mechanism of the present invention, and is a magnetism composed of a magnet sheet in which an article holding material is compounded on a magnetic wall surface similar to the magnetic wall shown in FIG. Indicates that shelves (combined L-shaped shelves) are magnetically attached.
FIG. 12B is a conceptual schematic diagram (side view) showing a state in which a magnet sheet in which an L-shaped shelf is composited is magnetically attached to a magnetic wall as shown in FIG. 12A.
FIG. 12 (c) is a conceptual schematic diagram of the front view.
It is shown that a magnetic shelf made of a magnet sheet obtained by combining a magnet sheet on a magnetic wall and an L-shaped shelf between the same poles can be easily aligned and attached to the magnetic wall.
Since the ferromagnetic layer 8 is provided on the back surface of the magnetic sheet of the magnetic wall, the magnet sheet is interposed between the ferromagnetic layer 8 of the magnetic shelf (FIG. 11) when the magnetic shelf is magnetically attracted. Therefore, a magnetically closed circuit is formed and a large magnetic attraction force can be obtained.
Further, it is shown that the magnetic wall is attached at a position where the presence or absence of the difference in magnetic adsorption between the intermediate portion and the non-intermediate portion can be evaluated by the load bearing test.

Next, the main member used in the present invention will be described.
(1) Wall base of magnetic wall As the wall base of magnetic wall, conventional building materials are used without any specification, but fireproof materials (non-combustible materials, semi-non-combustible materials, difficult materials) specified by the Minister of Land, Infrastructure, Transport and Tourism or certified. Fuel material) is desirable, for example, gypsum board, fiber-reinforced calcium silicate board, inorganic board such as fiber-reinforced cement board, flame-retardant treated wood board such as flame-retardant plywood, zinc-plated steel plate, zinc-plated coated steel plate, magnetic stainless steel plate, etc. Examples include metal plate and decorative steel plate volcanic vitreous composite layer board.

(2) Magnetic layer The ferromagnetic layer used for magnetic walls, magnetic display pieces, magnetic shelves, etc. includes steel plates, magnetic stainless steel plates, iron powder, or sheets in which a small amount of binder is highly filled with iron powder or an alloy powder with iron. In the case of a metal plate, the thickness is about 25 μm to 500 μm, and in the case of a sheet in which iron powder or an alloy powder with iron is highly filled in a small amount of binder, it is preferably about 500 μm to 1500 μm. It becomes magnetically saturated with respect to the magnetic field, and the back leakage magnetic flux cannot be ignored. Further, if it is thicker than that range, the increase in magnetic performance cannot be expected, and the cutting process and workability are inferior, which is not preferable.

(3) Magnet sheet 1) As a magnet sheet used for magnetic walls, magnetic display pieces, magnetic article holding materials, etc., ferite magnet sheets such as strontium ferite and barium ferite, neodymium / iron / boron, samarium / iron / Examples include rare earth magnet sheets such as nitrogen, and commercially available multi-pole magnetized products can be used, but those with good dimensional accuracy between the poles are desirable, and those that are inferior are the magnet sheet on the magnetic wall side and the surface material or display. A decrease in magnetic attraction or magnetic repulsion is caused by a displacement between a magnetic display piece made of a magnetic sheet made of a composite material or an article holding material, a magnetic shelf, or the like.

Further, depending on the application, a blocking (self-adhesion phenomenon due to temperature, load, and time) prevention layer with the adherend surface can be provided on the magnetized surface of the magnet sheet used for the magnetic display piece or the like.

2) The magnet sheet is preferably a magnet sheet in which anisotropic strontium ferite powder is highly filled in an organic polymer elastomer from the viewpoint of obtained performance and economy, and the magnetic property is preferably about BHmax1.5MGOe, which is 0. The thickness is 3 mm to 5.0 mm, and the distance between the poles of multi-pole magnetization may be determined in the range of 2 mm to 7 mm pitch depending on the application. Then, the dimensional accuracy between the poles is preferably about + 1% to -1% between the poles, and if it deviates from that range, the decrease in the magnetic adsorption force cannot be ignored.

3) The thickness of the surface material of the magnet sheet is preferably about 50 μm to 250 μm. If it is thinner than this, the hiding power is inferior and the natural color of the magnet sheet cannot be hidden. It is not preferable because it cannot be ignored.

4) As the magnet sheet, a single-sided magnetized product or a double-sided magnetized product in which magnetic fields are applied from one side or both sides using a multi-pole yoke to form magnetic poles on both sides can be used by a known method. In the case of a single-sided magnetized product in which magnetic poles are formed on both sides by applying a magnetic field from one side with a multi-pole yoke, the surface to which the magnetic field is applied has a stronger magnetic attraction than the back surface, so that the back surface is ferromagnetic. If no body layer is provided, the non-magnetized surface is laminated on the non-magnetic plate of the adherend using an adhesive or pressure-sensitive adhesive, and the surface side that utilizes the magnetic attraction is the magnetized surface. When a ferromagnetic layer is provided on the back surface, a double-sided magnetized product in which magnetic poles are formed on both sides by applying a magnetic field with a multi-pole yoke from both sides is used to magnetize the ferromagnetic layer of the adherend. In addition to being able to be attached, a strong magnetic attraction can be obtained by further preventing back leakage magnetic flux.

5) When the distance between the poles of the magnet sheet is sufficiently larger than the thickness of the magnet sheet (for example, the thickness between the poles is 3 mm and the thickness is 0.6 mm), the magnetic wall magnet sheet to be magnetically attracted and the magnetic display piece or the article holding material composite magnet sheet When the ferromagnetic layer is provided on both back surfaces of the above, a magnetically closed circuit is formed at the time of magnetic attachment to increase the magnetic attraction force, and in addition, the magnetic attraction force obtained is the same as that of the single-sided magnetized product. A single-sided magnetized product that is easy to magnetize is preferable because the difference between the use and the use of the double-sided magnetized product is not recognized.

(4) Laminating a magnet sheet on a wall substrate In addition to laminating a magnet sheet on a wall substrate using an adhesive or a pressure-sensitive adhesive, a ferromagnetic layer (iron plate, etc.) may be laminated on the wall surface. By laminating with a pressure-sensitive adhesive and attaching a magnet sheet with magnetic poles formed on both sides by single-sided or double-sided magnetization with magnetic attraction, it is easy to correct or replace the attachment position. Further, it is preferable because the effect of preventing leakage of the magnetic flux to the wall substrate side can increase the magnetic attraction force between the magnetic wall and the magnet sheet in which the display material is combined.

(5) Article holding material The article holding material used for the magnetic display mechanism may be a material whose back surface is partially or wholly smooth, for example, an L-shaped shelf, a box-shaped shelf, a blanket for a wall-mounted television, a picture frame for painting, or the like. Can be mentioned.

Next, the present invention will be described in more detail by way of examples, but the present invention is not limited to such examples.

≪Next, the test method for performance evaluation will be explained≫

(1) Observing the appearance of the magnetic wall The appearance of the magnetic wall is visually observed over the entire magnetic wall, such as the linearity of the seams at the middle reliever and the degree of opening, and evaluated in three stages.
○: Good, △: Slightly inferior, ×: Inferior

(2) Interpole image of the relay point Using a magnetic viewer sheet, observe whether there is a difference from the poles of the non-relay point, and evaluate in three stages.
○: Good, △: Slightly inferior, ×: Inferior

(3) Measurement method of magnetic adsorption force (measurement of difference between magnetic adsorption force at relay points and magnetic attraction force at non-relay points)
Magnetically attached to the flat surface of a jig with a hook in the center of the back of a square smooth plastic plate with a side of 70 mm, which is a square with a side of 60 mm collected from a magnetic display piece and attached using double-sided adhesive tape. The adsorption force measurement sample is magnetically attached to the measurement point of the magnetic wall by the same pole repulsion / different pole suction. Then, the force required to separate the magnetic surface in the direction perpendicular to the magnetic surface is measured to calculate the magnetic attraction force per unit area (g / cm ² ). (See Fig. 14 for the measurement method of magnetic attraction) (See Fig. 13 for the measurement points of the magnetic wall)

(5) Pasting workability The pasting work is actually performed and evaluated in three stages.
○: Good, △: Slightly inferior, ×: Inferior
≪Next, I will explain the test results≫

The test results of the magnetic wall, the magnetic display piece of the magnetic display mechanism, and the magnetic shelf obtained in Examples and Comparative Examples are summarized in the table. That is, for the magnetic wall, Table 1 shows an example and Table 2 shows a comparative example. Table 3 shows examples and Table 4 shows comparative examples of the magnetic display pieces of the magnetic display mechanism. Table 5 summarizes the examples and comparative examples of the magnetic shelves.

(1) Magnetic wall << Example >> (Table 1)
1) Example 1 is a magnetic wall in which a magnet sheet (single-sided magnetized product) in which a surface material is laminated on a wall substrate is laminated using a pressure-sensitive adhesive (adhesive) and a middle reliever is in the horizontal direction. be.
The middle reliever was processed according to the specifications of the present invention, that is, after the magnetic field in the thickness direction was applied to one end of the magnet sheet facing each other when the middle reliever was attached in the horizontal direction to erase the magnetic pole end, the middle reliever was formed. By aligning the center lines of the magnetic poles so that the center lines of the magnetic poles of the same pole in the front and back match, and sticking them together, the same magnetic pole arrangement and pole spacing as in the non-middle reliever part can be obtained. In the polar image (magnetic viewer sheet image) of, the coincidence of the magnetic pole center lines of the middle reliever is recognized. (Good)

Then, in the magnetic attraction force (FIG. 13), in the middle reliever attachment portion, the magnetic pole erasing portion of the middle reliever portion is present at 3 mm × 60 mm (5.00% in area ratio) while the size of the measurement piece is 60 mm × 60 mm. .. In this case, the magnetic attraction force is proportional to the area of the magnetized surface, so the magnetic attraction force of the portion including the magnetic pole erasing portion is the magnetic attraction force of the non-middle reliever portion × 95.00%, for example, the non-middle reliever portion 68 g / cm. With respect to ² , the portion including the middle reliever is 65 g / cm ² , which is a value that is not practically problematic. To give an example, when the size of the magnet sheet of the L-shaped magnetic shelf is 100 mm × 380 mm, the part including the middle reliever part / the non-middle reliever part = 100 × (380-3) / 100 × 380 = 99.21%, which is 68 g / cm. ² × 0.99 = 67 g / cm ² , and the difference is negligible.

2) In Example 2, the effect of the present invention is recognized in the same manner as in Example 1. In addition to having a ferromagnetic layer (iron powder composite layer) on the surface side of the wall substrate and having magnetic poles formed on both sides, a single-sided magnetized magnet sheet can be attached by the magnetic attraction of the magnet sheet. Since leakage magnetic flux to the substrate side can be prevented, the effect of increasing the back magnetic flux of the magnet sheet can be obtained, and excellent magnetic attraction is obtained even if the thickness of the magnet sheet is as thin as 0.4 mm.

3) In Example 3, the effect of the present invention is recognized in the same manner as in Example 1. Further, since the wall substrate has a ferromagnetic layer (decorative steel plate) on the surface side, it can be attached by the magnetic attraction force of a single-sided magnetized magnet sheet having magnetic poles formed on both sides, and also leaks to the wall substrate side. Since the ability to prevent magnetic flux is strong and the effect of increasing the magnetic flux on the back surface of the magnet sheet is excellent, even if the thickness of the magnet sheet is as thin as 0.4 mm, excellent magnetic attraction is obtained.

4) In Example 4, the effect of the present invention is recognized in the same manner as in Example 1. Further, by setting the magnet sheet to be 0.6 mm thick with a single-sided magnetized product and having a thickness (220 μm) of a ferromagnetic layer (decorative steel plate) suitable for the magnet sheet, a strong magnetic adsorption force is naturally obtained.

<< Comparative example >> (Table 2)
Comparative Example 1 is compared with Example 1, Comparative Example 2 is compared with Example 2, Comparative Example 3 is compared with Example 3, and each Comparative Example deviates from the middle reliever specification of the present invention. As a matter of course, each evaluation performance is inferior.

2. Magnetic display mechanism (1) Magnetic display piece << Examples >> (Table 3)
Regarding the magnetic adhesiveness of Examples 5 to 8, there is no difference between the middle reliever and the non-middle reliever of the magnetic wall. In addition, excellent results are also obtained in each of the close attachment (F1 / F2) and the attachment (F2 / F3 / F4) at one pole interval.

<< Comparative example >> (Table 4)
The magnetic sticking property of Comparative Examples 5 to 8 is such that the display piece is lifted at the place where the display piece is pressed due to the inferior cutting accuracy of the display piece in the proximity sticking (F1 / F2). Since the sticking is performed across the extreme deviation of the joint portion of the magnetic wall, the attachment failure occurs, and in F3, the attachment is caused by the attachment straddling the extreme deviation of the middle joint portion, so that the adhesion failure occurs. That is, since each comparative example deviates from the middle reliever specification of the present invention, each evaluation performance is naturally inferior.
Only F4, which is the attachment at the non-middle reliever, naturally exhibits normal attachment.

(2) Magnetic shelf << Example >> (Table 5)
In Examples 9, Example 10, and Comparative Example 10, since they have a ferromagnetic layer, a magnetically closed circuit is formed in magnetic adsorption, and a pressure-sensitive adhesive of a foam base material between the ferromagnetic layer and the back surface of the shelf. By interposing a layer, a good magnetic attraction force can be obtained by preventing the formation of an air gap between the magnet sheet of the magnetic wall and the magnet sheet of the magnetic shelf, and further, Examples 9 and 10 have anti-slip layer resistance. The effect of increasing the loadability is remarkable. Further, as can be seen from Examples 9 and 10, by forming a magnetically closed circuit, there is no difference in magnetic attraction between single-sided magnetizing and double-sided magnetizing, so that there is no difference in magnetic attraction between single-sided magnetized products and double-sided magnetized products in terms of load bearing capacity. There is no difference between porcelain products. As a result, Comparative Example 9 does not have a ferromagnetic layer, a pressure-sensitive adhesive layer of a foam base material, and an anti-slip layer, so that the load bearing capacity is naturally inferior.
Further, in Example 9, Example 10, Comparative Example 9, and Comparative Example 10, no difference between the intermediate portion and the non-intermediate portion of the magnetic wall is observed due to the effect of the present invention. (Good)

As can be seen from the above test results, according to the present invention, the magnetic display piece and the magnetic shelf of the present invention are mounted on the magnetic wall of the present invention regardless of the thickness and magnetic attraction of the magnet sheet and the presence or absence of the ferromagnetic layer. By using this, it is possible to perform excellent alignment and sticking in the magnetic pole direction on the entire surface regardless of the intermediate portion and the non-interjunment portion of the magnetic sheet of the magnetic wall.
Further, in a magnetic shelf or the like, the ferromagnetic layer is magnetically attached to a magnetic wall to form a magnetically closed circuit, and a pressure-sensitive adhesive (adhesive) using a foam as a base material is used to form a magnetically attached surface. By preventing the formation of an air gap, a large magnetic attraction force can be obtained, and by further providing an anti-slip layer, the slip resistance increases and the shear magnetic attraction force increases, so that excellent load resistance can be obtained. I understand.

According to the present invention, even if the magnetic wall has a large area, it is possible to align and attach magnetic display pieces, magnetic shelves, etc. in the magnetic pole direction of the magnetic sheet of the magnetic wall on the entire surface continuously regardless of the joint location. As a result, it is expected to be applied to large magnetic display mechanisms and the like.
