Description

The present invention relates to magnetic wall mounting articles and magnetic wall mounting systems. More specifically, the present invention relates to a magnetic attachment type attachment article that can be detachably attached to a magnetic wall using magnetic attraction force, and a magnetic wall attachment system.

In recent years, due to the cat boom, more and more people are keeping cats at home. Under such circumstances, a system that makes it possible to install a removable magnetic cat step stool by installing a magnetic adhesion panel on the indoor wall is gaining popularity. As a cat step stool, an L-shaped shelf is used, for example as shown in Patent Document 1 below, which has a magnetic sheet attached to a back plate and a mounting plate orthogonal to the back plate. In this system, the L-shaped shelves are removable using magnets, so multiple L-shaped shelves can be installed on the wall in any desired arrangement. For example, by installing it like a staircase, you can create a play space indoors where cats can climb up and down.
JP2021-61285

In the above-mentioned system, the magnetic sheet has a strong magnetic adsorption to prevent the steps from falling off the wall when going up and down, even if the height difference between adjacent steps is large or the cat gains weight as it grows. power is required. However, increasing the magnetic adsorption force means that a large force is required when removing it.
By the way, you need to change the placement of the step stool from time to time to keep your cat from getting bored. For this reason, the step stool of this system is required to have a strong magnetic adhesion force while not requiring a large force for removal. These conditions apply not only to cat stepping stools, but also to magnetic storage boxes and picture frames that you may want to rearrange from time to time.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a magnetic wall-mounted article and a magnetic wall-mounted system that can be easily removed without impairing the magnetic adsorption force to the magnetic wall.

The present invention takes the following measures to solve the above problems. Note that the numbers in parentheses attached to each component means in this column ("Means for solving the problem" column) are for reference only to show the correspondence with specific means described in the embodiments described later. However, the configuration means of the present invention is not limited to this.

One aspect of the present invention is a magnetic wall-mounted article (2) that is detachably attached to a magnetic wall (1) by magnetic attraction force, and includes a back plate (22) made of a rigid body and attached to the magnetic wall (1). The article body (20) to which the is attached, and a magnet sheet (3) affixed to a back plate (22), the magnet sheet (3) is attached to a facing area (3B) facing the back plate (22). ) is characterized by having a non-adhering region (3N) that is continuously non-adhesive to the back plate (22) at approximately the lower half of the portion.

In another aspect of the present invention, in the magnetic wall-mounted article (2), the non-stick area (3N) is at least 3 times the height of the back plate (22) from the top end (22U) of the back plate (22). It is formed below the 2/2 lower position (22M).

In another aspect of the present invention, the article main body (20) includes a mounting plate (21) made of a rigid body and perpendicular to the back plate (22).

In another aspect of the invention, the back plate is made of soft magnetic material.

Another aspect of the invention is a magnetic wall mounting system (100, 200, 300, 400) comprising a magnetic wall mounting article (2) according to any one of the above aspects, and a ferromagnetic layer (12). It is characterized by having a magnetic wall (1, 1A) having a magnetic wall (1, 1A).

Another aspect of the present invention is a magnetic wall mounting system (400) comprising the magnetic wall mounting article (2) according to any one of the above aspects and a magnetic wall (1A) having a ferromagnetic layer. The magnetic wall (1A) has a wall magnet sheet (6) attached so that the magnetized lines (63) are parallel to the horizontal direction as a wall material, and the magnet sheet of the magnetic wall-mounted article (2) (3) has the same magnetization pitch as the wall magnet sheet (6), so that the magnetization line (33) of the magnet sheet (3) of the magnetic wall-mounted article (2) is parallel to the horizontal direction. It is characterized in that a magnetic wall-mounted article (2) is magnetically attached to a magnetic wall (1A).

The main effects of the embodiments of the present invention are described below.
In the magnetic wall-mounted article (2), the back plate (22) is made of a rigid body. On the other hand, the magnetic sheet (3) has flexibility and is continuously non-adhered to the back plate (22) approximately in the lower half of the facing area (3B) facing the back plate (22). It has a non-stick area (3N). The magnet sheet (3) is attached to the back plate (22) at the uppermost end (22U) of the back plate (22).

Here, in the adhesion area (3G), the magnet sheet (3) is integrated with the back plate (22), and operates as one with the back plate (22). In other words, when the back plate (22) is rotated, the magnet sheet (3) also rotates in synchronization with (completely accompanying) the rotation. This has the effect of peeling off the magnet sheet (3) from the magnetic wall (1). On the other hand, in the non-adhering area (3N), the magnet sheet (3) is not integrated with the back plate (22) and moves not completely in synchronization with the rotation of the back plate (22).
Now, when removing the magnetic wall-mounted article (2) that is magnetically attached to the magnetic wall (1) by the magnetic sheet (3) from the magnetic wall (1), the uppermost end (22U) of the magnetic sheet (3) is When the magnetic sheet (3) is rotated and an action is applied to peel it off from below, the following process occurs.

That is, as shown in FIG. 7, in the sticking area (3G) where the back plate (22) is stuck to the magnet sheet (3), the force trying to peel off the magnet sheet (3) is concentrated. Although the central portion (a1) is peeled off, the force for peeling off becomes gentler in the non-adhesive area (3N). As a result, for example, the magnet sheet (3) does not peel off from the magnetic wall (1) at the lower part (a2) near the non-adhering area (3N), but after that, by further applying the above action, the lower part (a2) also peels off. go.
In this way, when removing the magnetic wall-mounted article (2) from the magnetic wall (1) in the above manner, the entire magnetic surface of the magnetic sheet (3) is not peeled off from the wall surface at once, but the center portion (a1), It peels off in the order of the lower part (a2). In other words, rather than applying a large force all at once, a relatively small force can be applied in multiple steps and removed in stages, making the removal process easier.

According to the present invention, there are provided a magnetic wall mounting article and a magnetic wall mounting system that can be easily removed without impairing the magnetic adsorption force to the magnetic wall.

[First embodiment]
FIG. 1 is a perspective view of a magnetic wall mounting system 100 according to a first embodiment, in which (a) is an overall image diagram, and (b) is an enlarged view of the dashed-dot line portion in (a). FIG. 2 is a side view of FIG. 1(b). FIG. 3 is a two-sided view of the magnet sheet 3 on the L-shaped shelf 2, with (a) showing a front view and (b) showing a side view.

As shown in FIG. 1(a), the magnetic wall mounting system 100 includes a magnetic wall 1 installed indoors in a general household and a plurality of L-shaped shelves 2 attached to the magnetic wall 1. It functions as a playground space. That is, a cat kept indoors can go up and down the L-shaped shelf 2 arranged in the form of stairs. Each L-shaped shelf 2 is detachably attached to the magnetic wall 1 by a magnet sheet 3 provided on the back side. Therefore, the L-shaped shelf 2 can be freely attached and detached without requiring fixing parts such as screws, and the arrangement pattern and type of items can be changed as appropriate.

Next, each component of the magnetic wall mounting system 100 will be explained.
The magnetic wall 1 has a soft magnetic board 10 and a wall material film 13, as shown in FIG. 1(b).

The soft magnetic board 10 includes a gypsum board 11 and a soft magnetic layer 12 laminated on one side of the gypsum board 11 by coating. A specific example of such a soft magnetic board 10 is Tiger Fe Board (registered trademark) manufactured by Yoshino Gypsum Co., Ltd. Note that Magpita Board (registered trademark) may be used instead of the above-described gypsum board with a soft magnetic layer. Magpita board is made by laminating a decorative steel plate layer on one side of an inorganic board. Alternatively, a steel plate or a board obtained by laminating a facing sheet or a functional sheet on a steel plate may be used.

The wall material film 13 is a decorative wall material in the form of a film with a thickness of several tens of microns to several hundred microns, and includes an ink layer on which a picture or pattern is printed on the upper surface of a base film (not shown). As the base film, thermoplastic resins such as polyvinyl chloride resins and polyethylene resins on which an ink-receiving layer is formed, or thin paper materials can be used. Ink is fixed on this ink-receiving layer by printing according to the application. Printing methods include offset printing, letterpress printing, inkjet printing, thermal transfer printing, and the like.

The magnetic wall 1 has a structure in which a wall material film 13 is laminated on a soft magnetic board 10 via, for example, a urethane adhesive. It is fixed to a wall base (not shown) made of concrete or light metal using nails, screws, adhesives, double-sided adhesive tape, staples, etc.

The L-shaped shelf 2 includes a main body 20 and a magnet sheet 3, as shown in FIGS. 1(b) and 2.
The main body section 20 is constructed by joining or bending two rectangular rigid plates made of wood, synthetic resin, or metal so that they are L-shaped when viewed from the side. It includes a plate 21 and a back plate 22. Specifically, the mounting plate 21 is perpendicular to the lowermost position of the back plate 22.
The mounting plate 21 functions as a platform for the cat to rest on.
The back plate 22 is a portion facing the magnetic wall 1 to which it is attached, and its back surface is a flat surface to which the magnet sheet 3 can be attached (fixed) with an adhesive.

The magnet sheet 3 is a flexible sheet-like magnet that is one size larger than the back plate 22 in the height direction (Z direction), and is overframed upward from the back plate 22 on the back surface of the back plate 22. It is attached with adhesive G in this state. That is, the upper edge 3U of the magnetic sheet 3 is located at a distance L1 upward from the uppermost end 22U of the back plate 22, and is attached to the back plate 22 so as to have an overframe area 3V from the back plate 22.
More specifically, the overframe region 3V is formed in a shape that protrudes above the back plate 22 in the height direction Z, and the length L1 in the height direction Z is equal to the length of the back plate 22 in the height direction Z. It is 0.4 to 1.0 times the length L2. This is based on the ease with which the magnet sheet 3 can be removed from the magnetic wall 1 and the strength of the magnetic attraction force.

Here, the magnet sheet 3 is attached to the back plate 22 not over the entire back surface of the back plate 22, as shown in FIG. Only the pasting area 3G, which is a part of the area 3B, is covered. The sticking area 3G is an area between the uppermost end 22U of the back plate 22 and a lower position 22M of about two-thirds of the total length of the back plate 22 in the height direction Z from the uppermost end 22U. That is, the area between the lower position 22M and the lowermost end 22L of the back plate 22 is a non-adhering region 3N where no adhesive is applied. In other words, a non-adhering region 3N that is continuously non-adhesive to the magnet sheet 3 is provided in substantially the lower half of the back plate 22.

As will be described later, the non-adhering area 3N is for relaxing the force applied at once when the L-shaped shelf 2 is peeled off from the magnetic wall 1 so that the upper adhesive end 3M1 of the magnetic sheet 3 serves as the rotation axis. This contributes to If this non-adhering area 3N is provided in a range above the lower position 22M of about two-thirds of the total length in the height direction Z of the back plate 22, the effect of reducing the load capacity cannot be ignored.

The magnet sheet 3 is made by magnetizing the surface of a sheet formed by rolling or extruding a mixture of fine powder of a hard magnetic material and a small amount of organic polymer elastomer as a binder. It is manufactured by The magnet sheet 3 is of a multi-pole magnetized type on both sides. That is, as shown in FIG. 3, magnetic poles 31 and 32 (N poles and S poles) of a constant width and different polarities are formed alternately in stripes at equal intervals on each of the front and back surfaces, and magnetized lines are formed at a constant pitch. It has 33. The thickness of the magnet sheet 3 is 1 mm to 5 mm. Here, the magnetized line 33 is an imaginary boundary line between any one magnetic pole 31 on the surface of the multi-pole magnetized magnet sheet 3 and the adjacent magnetic pole 32 having a different polarity. In reality, this is the part that appears white when a magnetic viewer sheet (magnetic fluid microcapsules are uniformly dispersed in the film) is placed in close contact with the magnetic viewer sheet, and it is the part that appears white when the magnetic viewer sheet (magnetic fluid microcapsules are uniformly dispersed in the film) is placed in the normal direction of the magnetic sheet surface, that is, perpendicular to the surface. A region where the magnetic field in the direction is extremely weak or zero. In other words, the magnetized line 33 means an imaginary line on the sheet surface. In the side view, the magnetized lines 33 are located at both ends of the magnet sheet 3 in the thickness direction.
Note that in order to obtain sufficient magnetic attraction force, it is preferable to use an anisotropic hard magnetic material. Furthermore, a removable adhesive layer can be provided on the magnetically attached surface of the magnet sheet 3 to further strengthen the adhesion to the magnetic wall surface.

Next, the first effect specific to the magnetic wall mounting system 100 will be explained using FIG. 4.
FIG. 4 is a side view for explaining the force acting on the magnetic wall mounting system 100 of the first embodiment, in which the L-shaped shelf 2 with the load D placed on the mounting plate 21 is magnetically attached to the magnetic wall 1. Indicates the state in which In FIG. 4, (a) shows a form in which the magnet sheet 3 has an overframe area 3V, and (b) shows a form in which the magnet sheet 3 does not have an overframe area 3V. In both (a) and (b), it is assumed that the load D is the maximum weight that each system can hold. In other words, if this weight is exceeded, L-shaped shelf 2 will fall off.

In each state of (a) and (b), the following force balance equation holds true in the Z direction.
Regarding (a),
Q1=μ×P1=W1
P1=S1×P0
Regarding (b),
Q2=μ×P2=W2
P2=S2×P0

Here, Q is the upward force in the Z direction acting on the L-shaped shelf 2, μ is the coefficient of static friction between the magnet sheet 3 and the magnetic wall 1, and P is the magnetic force acting between the magnet sheet 3 and the magnetic wall 1. The attraction force, S is the area of the magnetic surface of the magnet sheet 3, P0 is the magnetic attraction force per unit area acting between the magnet sheet 3 and the magnetic wall 1, and W is the total load of the L-shaped shelf 2 and the load D. be. "1" and "2" appended to the end of each alphabetic code distinguish between (a) and (b), and "1" indicates the form (a), and " 2'' indicates the form (b).

Regarding (a), since the magnet sheet 3 has an overframe area 3V, S1>S2. Therefore, since P1>P2, W1>W2.
That is, in (a) a larger load capacity can be obtained than in (b).
This is a technical concept that takes advantage of the excellent property of magnetic sheets, which can obtain strong holding power by attracting magnets not at points but at surfaces.

In addition, on the mounting plate 21 of the L-shaped shelf 2, the Y-direction position of the center of gravity 25 of the load W is located a certain distance from the wall surface of the magnetic wall 1, so the moment M in the clockwise direction in FIG. occurs. In other words, the action is to rotate the magnet sheet 3 clockwise about the lowermost portion 3L of the magnet sheet 3 as an axis. This moment M acts to peel off the magnetic sheet 3 on the L-shaped shelf 2 from the magnetic wall 1.

The strength of this action is determined by the product of the load W and the distance r in the Y direction between the lowermost part 3L of the magnet sheet 3 and the center of gravity 25 of the load W on the L-shaped shelf 2.
In addition, the strength of the action against this is determined by the magnetic force P acting between the magnet sheet 3 and the magnetic wall 1, the center of gravity 35 of the magnetic force P in the magnet sheet 3, and the lowest part 3L of the magnet sheet 3. It is determined by the product of the Z direction distance (arm) between. And both effects are balanced.

If we express the above contents in a formula,
Regarding (a), M1=W1×r1=P1×h1.
Regarding (b), M2=W2×r2=P2×h2.
By providing the overframe region 3V on the upper side, the center of gravity 35 of the magnetic force P moves upward, and a long arm h1 can be ensured. The longer the arm h1, the stronger the effect of resisting the force of trying to peel off the magnetic sheet 3. That is, it is preferable that the overframe region 3V be formed above the back plate 22.

Next, a second effect specific to the magnetic wall mounting system 100 will be explained using FIG. 5. FIG. 5 is a perspective view for chronologically explaining an example of the procedure and state when removing the L-shaped shelf 2 from the magnetic wall 1.
Since the magnet sheet 3 has flexibility in the overframe area 3V, when removing the L-shaped shelf 2, as shown in FIG. By pulling and turning it over, the magnet sheet 3 magnetically attached to the magnetic wall 1 can be gradually peeled off.

Then, as shown in FIG. 5(b), when the lowermost part of the overframe region 3V (the boundary between the back plate 22 and the magnet sheet 3), that is, the upper adhesive end 3M1 has been peeled off, force is applied all at once to remove it. Since a long arm L3 can be secured from the upper end corner T1 to the lowest bottom 3L of the magnet sheet 3, the principle of leverage can be used, and removal can be performed with a weak force. For example, compared to removing the mounting plate 21 by pulling the left and right ends of the mounting plate 21 all at once with the left and right hands, the work is easier, and even children and women with relatively weak strength can easily remove the mounting plate 21.

Next, the third effect specific to the magnetic wall mounting system 100 will be explained using FIGS. 6 and 7. FIG. 6 is a side view for chronologically explaining another example of the procedure and state when removing the L-shaped shelf 2 from the magnetic wall 1, and FIG. 7 is an enlarged view of FIG. 6(b). be.
Here, a case will be shown in which the L-shaped shelf 2 magnetically attached to the magnetic wall 1 is removed by applying an upward force F2 to the near side position of the mounting plate 21.

FIG. 6A shows an initial state in which the L-shaped shelf 2 is magnetically attached to the magnetic wall 1 via the magnet sheet 3 attached to the back plate 22. In this state, the magnet sheet 3 is magnetically attached to the magnetic wall 1 over its entire magnetic surface.

When force F2 is applied to the mounting plate 21 in the state shown in FIG. 6(a), the L-shaped shelf 2 rotates counterclockwise around the upper adhesive end 3M1 as shown in FIG. 6(b). Start. FIG. 6(b) shows a state in which the L-shaped shelf 2 has started rotating and is tilted by a small angle θ1 from the vertical axis. At this time, in the non-adhering area 3N of the magnet sheet 3, the space between the back plate 22 and the magnet sheet 3 expands into a substantially "V" shape. At the same time, the central portion a1 of the magnet sheet 3 peels off from the magnetic wall 1 in a locally deformed manner so as to bulge out in a substantially convex shape when viewed from the side. The reason for this will be explained later.
Thereafter, by continuing to apply force F2, the lower part a2 of the magnet sheet 3 is peeled off as shown in FIG. 6(c), and then the upper edge 3U of the magnet sheet 3 is rotated as shown in FIG. Due to this rotation, the upper part a3 is peeled off.

In this way, when removing the L-shaped shelf 2 from the magnetic wall 1 using the above procedure, the entire magnetic surface of the magnetic sheet 3 will not be peeled off from the wall surface at once, but the center part a1, the lower part a2, and the upper part a3 will be peeled off in this order. To go. In other words, rather than applying a large force all at once, a relatively small force can be applied in multiple steps and removed in stages, making the removal process easier.

Next, the principle of the above-mentioned peeling of the magnetic sheet 3 on the L-shaped shelf 2 will be explained mainly using FIG. 7.

Now, when force F2 is applied to the mounting plate 21 from the initial state shown in FIG. 6(a), this system causes the L-shaped shelf 2 to rotate counterclockwise around the upper adhesive end 3M1. Moment M3 acts. The magnitude of moment M3 can be expressed as M3=F2×R (see FIG. 6(a)). Here, R is the distance in the Y direction between the wall surface of the magnetic wall 1 and the force F2, and the magnitude of the force is also "F2".

The main body 20 of the L-shaped shelf 2 is a rigid body, and the mounting plate 21 and the back plate 22 are integrated in such a manner that deformation due to external force can be ignored. On the other hand, the magnet sheet 3 alone can be said to be a flexible elastic body. Here, in the L-shaped shelf 2, the magnet sheet 3 is integrated with the back plate 22 in the sticking area 3G with the back plate 22, so it does not have flexibility in the sticking area 3G. On the other hand, the overframe region 3V and the non-adhering region 3N are not integrated with the back plate 22, and thus have flexibility. The portions of the magnet sheet 3 that are the boundary between flexibility and non-flexibility are the upper adhesive end 3M1 and the lower adhesive end 3M2 with respect to the back plate 22. The upper adhesive end 3M1 is located at a position corresponding to the uppermost end 22U of the back plate 22, and the lower adhesive end 3M2 is located at a position corresponding to the lower position 22M of the back plate 22.

Here, in the sticking area 3G, the magnet sheet 3 is integrated with the back plate 22, and operates as one with the back plate 22. That is, when the back plate 22 rotates, the magnet sheet 3 in the attachment area 3G rotates in complete synchronization with this rotation. This serves to peel off the magnet sheet 3 from the magnetic wall 1. On the other hand, in the non-stick area 3N, the magnet sheet 3 is not integrated with the back plate 22, and the magnet sheet 3 in the non-stick area 3N operates not in complete synchronization with the rotation of the back plate 22. The magnetically attached surface of the magnet sheet 3 in the non-adhesive area 3N has a strong force to maintain the magnetically attached state to the magnetic wall 1, and does not peel off immediately except slightly above the lower part a2. As a result, the space between the back plate 22 and the magnet sheet 3 expands into a substantially V-shape. Moreover, since the magnet sheet 3 is deformable below the lower adhesive end 3M2, the lower part of the lower adhesive end 3M2 is peeled off while the lower part a2 is magnetically attached to the magnetic wall 1. As described above, the magnet sheet 3 is peeled off from the magnetic wall 1 in a convex shape at the central portion a1.

At this point, the magnetic force of the magnetic sheet 3 to the magnetic wall 1 has weakened by the peeled area.
When the force F2 is further applied, the angle θ1 increases due to the rotation, and the lower part a2 is also peeled off from the magnetic wall 1 as it is pulled by the magnetic sheet 3 in the sticking area 3G. As described above, since the magnetic attraction force to the magnetic wall 1 is weakened, the force required for peeling off at this time may be small. Note that the non-stick area 3N is located in the lower half of the magnetic sheet 3, and when the L-shaped shelf is fixed to the magnetic wall 1, it is pressed against the magnetic wall 1 side by a clockwise moment, so the magnet This does not cause a decrease in the magnetic adhesion of the sheet 3.

[Second embodiment]
FIG. 8 is a side view of the magnetic wall mounting system 200 of the second embodiment. As shown in FIG. 8, in the magnetic wall mounting system 200, a wall material film 13V is adhered to the non-magnetic surface side of the overframe region 3V of the L-shaped shelf 2 with an adhesive (not shown). The other configurations are the same as those in the first embodiment, and the same components are given the same reference numerals and explanations will be omitted. The wall material film 13V has a surface decorated with the same type or similar decoration as the surface of the wall material film 13. Therefore, the overframe region 3V visually matches the surface of the magnetic wall 1, eliminating any discomfort. Note that the outer shape of the overframe region 3V may be formed into a design, for example, a part of an animal or a flower, or a curved shape.

[Third embodiment]
FIG. 9 is a side view of a magnetic wall mounting system 300 according to a third embodiment. As shown in FIG. 9, the magnetic wall mounting system 300 includes a cushion material 4 between the back plate 22 and the magnet sheet 3 on the L-shaped shelf 2. As shown in FIG. The other configurations are the same as those in the first embodiment, and the same components are given the same reference numerals and explanations will be omitted.

The cushioning material 4 is a flat rectangular parallelepiped-shaped elastic body having the same surface size as the surface area of the back plate 22 . The thickness is 1 mm to 5 mm, and the material is, for example, styrene foam, urethane foam, rubber sheet, etc. One surface is fixed to the non-magnetic surface of the magnet sheet 3 via an adhesive G, and the other surface is fixed to the back surface of the back plate 22 via an adhesive (not shown).

According to the magnetic wall mounting system 300, even when a cat lands on another L-shaped shelf 2 placed at a high place, the shock applied to the L-shaped shelf 2 is absorbed and alleviated by the cushioning material 4, and the magnet sheet 3, thereby preventing the L-shaped shelf 2 from falling off.

[Modification of third embodiment]
FIG. 10 is a side view of a magnetic wall mounting system 310 as a modification of the third embodiment. As shown in FIG. 10, the magnetic wall mounting system 310 includes a cushioning material 4 between the back plate 22 and the magnet sheet 3 on the L-shaped shelf 2, and a non-stick area 3N of the magnetic sheet 3 on the back plate 2. A soft magnetic material piece 7 made of a soft magnetic material such as a steel plate is attached to a portion corresponding to the soft magnetic material by, for example, an adhesive (not shown). That is, the cushion material 4 is provided only in the portion of the magnet sheet 3 that corresponds to the attachment area 3G.
In the magnetic wall mounting system 310, as shown in FIG. 10, when the L-shaped shelf 2 is fixed to the magnetic wall 1, the surface of the soft magnetic piece 7 is magnetically attached to the magnet sheet 3, and the soft magnetic piece The load capacity can be increased compared to the case without 7.

Further, as shown in FIG. 11, when the L-shaped shelf 2 is removed from the magnetic wall by applying a force F2, the upper part of the cushioning material 4 is compressed and the lower part is pulled, and at that time, the soft magnetic material pieces 7 detaches from the magnetic wall 1 first. Next, the magnet sheet 3 above the soft magnetic material piece 7 is peeled off. In other words, removal can be performed in a stepwise manner similar to the first embodiment described above.

[Fourth embodiment]
FIG. 12 is a side view of the magnetic wall mounting system 400 of the fourth embodiment, and FIG. 13 is a two-sided view of the magnet sheet 6 in the wall magnet sheet 5, with (a) showing a front view and (b) showing a side view. . FIG. 14 is an enlarged view of the circle in FIG. 12.
As shown in FIG. 12, the magnetic wall mounting system 400 includes a magnetic wall 1A instead of the magnetic wall 1 of the first embodiment. The other configurations are the same as those in the first embodiment, and the same components are given the same reference numerals and explanations will be omitted.

The magnetic wall 1A differs from the magnetic wall 1 of the first embodiment in the following points. That is, the magnetic wall 1 of the first embodiment has a structure in which the wall material film 13 is laminated on the soft magnetic board 10 via an adhesive, but the wall material board 1A has a wall magnet sheet on the soft magnetic board 10. 5 is magnetically attached.
As shown in FIG. 12, the wall magnet sheet 5 has a wall material film 13 laminated on the magnet sheet 6 via an adhesive (not shown). As shown in FIG. 13, the magnet sheet 6 is of a double-sided magnetized type having magnetized lines 63 at a constant pitch. The pitch width of the magnetized lines 63 is the same as the pitch width of the magnet sheets 3 of the L-shaped shelf 2.
This wall magnet sheet 5 is magnetically attached to the soft magnetic board 10 so that the magnetization lines 63 of the magnet sheet 6 are parallel to the horizontal direction.

In FIG. 12, the L-shaped shelf 2 is fixed to the magnetic wall 1A by the magnetic force acting between the magnet sheet 6 of the magnetic wall 1A and the magnet sheet 3 of the L-shaped shelf 2. At this time, the magnet sheets 3 and 6 are in a state where different polarities (N pole 31 and S pole 62, S pole 32 and N pole 61) are magnetically attached to each other, as shown in FIG. .
Thereby, the L-shaped shelf 2 is fixed to the magnetic wall 1A in a straight state without tilting from the horizontal direction. Therefore, the labor required to maintain the horizontal state of the L-shaped shelf 2 and attach it to the magnetic wall 1A is reduced.

Further, since the different polarities are magnetically attached to each other over the entire magnetically attached surface of the magnet sheet 3, the fixation is performed with a stronger magnetic force than in the first embodiment.
In addition, even if the magnet sheets 3 and 6 are made of isotropic magnetic material, the N and S poles are magnetically attached to each other, so they are stable semi-fixed, that is, they can be repeatedly attached and detached. It has a function that can be used at any time.

In each of the second to fourth embodiments, the same effect as in the first embodiment can be achieved by performing the same removal method as in the first embodiment. In particular, in the fourth embodiment, since the magnetic adhesion force of the L-shaped shelf 2 to the magnetic wall 1A is strong, it is difficult to remove the L-shaped shelf 2 by dividing the force into multiple steps and peeling it off in stages instead of applying a large force at once. It is effective for

[Other variations]
In each of the above-described embodiments, the magnet sheet 3 of the L-shaped shelf 2 has an overframe area 3V only in the upper part, but as shown in FIG. It may have a frame area 3W. Note that an overframe area may be provided in at least one of the lower left and right sides. Moreover, the main body part 20 is not limited to the L-shape, but may be a tunnel-shaped item with a window, which has entrances and exits at the left and right ends and an opening window 2H at the front, as shown in FIG. 15(b), for example. Further, as shown in FIG. 15(c), the overframe area V3 may not be provided.

Although the embodiments of the present invention have been described above, the embodiments disclosed above are merely illustrative, and the scope of the present invention is not limited to these embodiments. The scope of the present invention is indicated by the claims, and is intended to include all changes within the meaning and scope equivalent to the claims.

For example, if the back plate 22 of the main body 20 of the L-shaped shelf 2 is made of soft magnetic metal, such as steel or ferritic stainless steel, the magnetic flux density of the magnetic surface of the magnet sheet 3 increases due to the yoke effect. Increases wearing power. In other words, it has a higher load capacity than those made of wood or synthetic resin. On the other hand, by providing the non-adhering area 3N, the force required for the removal operation can be reduced. This makes it easier to remove and has a higher load capacity than shelves made of wood or synthetic resin.
In addition, for existing L-shaped steel shelves with full-surface adhesive magnetic sheets, we created a non-adhesive area for the magnetic sheets by removing part of the adhesive part of the magnetic sheets with a cutter blade, and You can also leave it as is and change it to a shelf that is easy to remove.

In addition, the configuration, structure, shape, size, number, material, arrangement, etc. of each part or the entire magnetic wall mounting system 100, 200, 300, 400 can be changed as appropriate in accordance with the spirit of the present invention. In addition, it can be used not only as a cat's step stool, but also for various objects such as various shelves for books and tableware, various types of furniture, and televisions with magnetic walls.

It can be widely used as a magnetic attachment article and attachment system that can be detachably attached to a magnetic wall using magnetic adsorption force.
