Description

TECHNICAL FIELD

[0001] The present invention relates to a magnetic wall-mountable article and a magnetic wall-mountable article system. More specifically, the present invention relates to a magnetically attached mounting article and system that is detachably attached to a magnetic wall by magnetic attraction force, and is particularly suitable for application to large or medium-sized furniture. BACKGROUND ART

[0002] In recent years, magnetic wall-mountable article systems have gained popularity. This system consists of a magnetic wall and a mounting article. The magnetic wall is a wall to which a magnet can attach, and the mounting article is a shelf, a picture frame or the like with a magnet sheet fixed to its back surface. The mounting article can be detachably fixed to the magnetic wall by the magnetic attraction force of the magnet sheet, and does not require mounting brackets or tools. Therefore, the original state of the wall surface can be maintained, and rearrangement and the like can be performed freely and easily (see Patent Document 1).

[0003] In the above magnetic wall-mountable article system, when it is desired to increase the load bearing capacity, it is effective to use a magnet sheet with strong attraction force for the mounting article, that is, a magnet sheet with a relatively large area and a large thickness. For example, a magnet sheet exceeding 10 cm in length × 20 cm in width and having a thickness of about 2 mm can attract and hold even a considerably heavy object. However, increasing the magnetic attraction force means that a large force is also required during removal, which hinders operations such as rearrangement. In particular, people with relatively low strength such as women and elderly people may not be able to remove it. In addition, since a magnet sheet with a large area is strongly magnetically attached, dirt from magnetic powder of the magnet sheet may adhere to the wall surface in some cases.

[0004] As an invention for solving such problems, the present applicant has proposed an assembly-type article storage device described in Patent Document 2. The assembly-type article storage device of Patent Document 2 is an assembly-type article storage device that is detachably attached to a magnetic wall surface by magnetic attraction force, and includes a fixing plate and a storage item that are separate from each other. The fixing plate includes a base plate and a magnet sheet, and has flexibility as a whole. The fixing plate and the storage item are combined by a connecting portion that detachably connects the two.

[0005] According to the assembly-type article storage device of Patent Document 2, the storage items are detachably attached to a fixing plate, and since the fixing plate is flexible, when removing the fixing plate, the storage items can be removed, and a part of the fixing plate can be bent and peeled off. In other words, instead of removing it all at once with strong force, it can be peeled off gradually from the edge with relatively weak force. For this reason, the removal work is easy, and it is particularly suitable for application to large or medium-sized furniture. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Utility Model Registration No. 3207754 [Patent Document 2] Japanese Patent Publication No. 2023-49026 [Disclosure of the Invention] [Problems that the invention aims to solve]

[0007] By the way, in the assembly-type article storage device described in Patent Document 2 mentioned above, when attaching it to a magnetic wall, the fixing plate is first magnetically attached to the magnetic wall, and then the storage items are attached to the fixing plate. In other words, the mounting state (position and orientation) of the storage items depends on the mounting state of the fixing plate. Therefore, if the storage items are mounted in a position that is not the desired mounting state, the storage items must be removed from the fixing plate and the fixing plate reattached. This correction process had to be repeated many times until the storage items were mounted in the desired position, which was time-consuming.

[0008] This invention has been made in view of the above circumstances, and aims to provide a magnetic wall mounting article and a magnetic wall mounting article system that can be easily removed from a magnetic wall and whose mounting state can be easily modified. [Means for solving the problem]

[0009] The present invention takes the following measures to solve the above problems. The symbols in parentheses attached to each component in this section ("Means for Solving the Problems") are for reference purposes only to indicate the correspondence with the specific means described in the embodiments later, and the present invention is not limited to these.

[0010] One aspect of the present invention is a magnetic wall mounting article system (100) comprising a magnetic wall (1) erected vertically and a magnetic wall mounting article (2) that is detachably fixed to the magnetic wall (1) by magnetic force, wherein the magnetic wall mounting article (2) comprises an article body (20) which is integrated with a first magnet sheet (51) and has a bearing surface (251) facing downward when the first magnet sheet (51) is magnetically attached to the magnetic wall (1), and a second magnet sheet (33) which is separate from the article body (20) and is integrated with the magnetic wall (1) The device comprises a fixing plate (30) having an upward-facing support surface (321), the first magnet sheet (51) having a magnetic force that allows the article body (20) to be held without falling off the magnetic wall (1) while magnetically attached to the magnetic wall (1), and that allows for easy removal of the article body (20) from the magnetic wall (1), and the second magnet sheet (33) of the fixing plate (30) being magnetically attached to the magnetic wall (1) with the support surface (251) of the article body (20) to which the first magnet sheet (51) is magnetically attached from below, and the support surface (321) of the fixing plate (30) in contact with the magnetic wall (1).

[0011] According to this embodiment, the fixing and holding of the article body (20) on the surface of the magnetic wall (1) is carried out by the first magnet sheet (51) and the second magnet sheet (33). The first magnet sheet (51) only needs to have the minimum magnetic force required to hold the article body (20), in other words, the minimum magnetic force that can hold the article body (20) without it falling off the magnetic wall (1). On the other hand, the second magnet sheet (33) supplements the magnetic force required when the magnetic force of the first magnet sheet (51) alone is insufficient for actual use, for example, when considering a safety factor or when heavy objects are stored or placed on the article body (20). Since the main body of the item (20) is fixed to the magnetic wall (1) by such a first magnetic sheet (51), it can be easily removed or moved while magnetically attached, and the mounting state (fixed state) can be easily modified.

[0012] Furthermore, when removing the magnetic wall-mounted item (2) from the magnetic wall (1), for example, as shown in Figure 10, first the second magnet sheet (33) of the fixing plate (30) is removed from the magnetic wall (1), and then the first magnet sheet (51) of the item body (20) is removed from the magnetic wall (1). In other words, instead of removing the magnet sheet with strong magnetic force all at once as in the conventional method, it becomes possible to remove the magnet sheet with relatively weak magnetic force in multiple steps, making removal easier. Thus, in this embodiment, removal from the magnetic wall is easy, and the mounting state can be easily modified. The reason for this configuration, in which the support surface (321) of the fixing plate (30) is brought into contact with the support surface (251) of the article body (20) from below, is to resist the gravitational force of the heavy object stored or placed on the article body (20). The second magnet sheet (33) becomes effective in this state.

[0013] In another aspect of the present invention, the fixing plate (30) has an outer edge region (311) that extends outward from the second magnet sheet (33) in a front view.

[0014] According to this embodiment, the inner surface (312) of the outer edge region (311) comes into contact with the surrounding surface (242) of the back plate (24), which can resist the force acting in the forward direction of the magnetic wall (1). Even when a large impact such as an earthquake occurs and the first magnet sheet (51) is about to come off, the movement of the article body (20) in the direction normal to the wall surface of the magnetic wall (1) can be restricted, preventing it from falling off.

[0015] In another aspect of the present invention, a plurality of fixing plates (30) are provided for each magnetic wall-mounted article (2).

[0016] According to this aspect, the magnetic adhesion force per second magnet sheet (33) can be reduced, making the removal of the fixing plate (30) easier.

[0017] In another aspect of the present invention, a lid member (40) is provided, which is inserted into the internal space (S1) of the article main body (2) and covers the fixing plate (30). According to this aspect, the exposure of the fixing plate (30) is concealed, so the appearance is improved.

[0018] Another aspect of the present invention is a magnetically mounted article (2) that is detachably fixed to a magnetic wall (1) by magnetic adhesion force, an article main body (20) which is configured with the first magnet sheet (51) as an integral part and has a supported surface (251) facing downward in a state where the first magnet sheet (51) is magnetically adhered to the magnetic wall (1), and a fixing plate (30) which is separate from the article main body (20), is configured with the second magnet sheet (33) as an integral part, and has a support surface (321) facing upward in a state where the second magnet sheet (33) is magnetically adhered to the magnetic wall (1), The first magnet sheet (51) is characterized by having a magnetic adhesion force that can hold the article main body (20) without falling off from the magnetic wall (1) in the state of being magnetically adhered to the magnetic wall (1), and that allows the article main body (20) to be removed from the magnetic wall (1) without excessive force. [Advantageous Effects of the Invention]

[0019] According to the present invention, there are provided a magnetically mounted article and a magnetically mounted article system that can be easily removed from a magnetic wall and allow easy correction of the mounted state. [Brief Description of the Drawings]

Figure 6 is an enlarged view showing the state when the fixing plate 30 is inserted into the through hole 25 of the back plate 24, with (a) being a front view and (b) being a side view.

[0023] As shown in Figure 1, the magnetic wall mounting system 100 includes a magnetic wall 1 installed in the room of a typical home, and a square-shaped shelf 2 that is detachably attached to the magnetic wall 1 by magnetic attraction.

[0024] The magnetic wall 1 has a soft magnetic board 10 and a wall material film 13, and is erected vertically.

[0025] The soft magnetic board 10 comprises a gypsum board 11 and a soft magnetic layer 12 laminated to 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. Alternatively, Magpita Board (registered trademark) can be used instead of the gypsum board with the soft magnetic layer described above. Magpita Board is made by laminating a decorative steel plate layer to one side of an inorganic board. In addition, a steel plate, or a board with a surface sheet or functional sheet laminated to a steel plate, may be used.

[0026] The wall material film 13 is a decorative wall material in the form of a film with a thickness of several tens to several hundred micrometers, and has an ink layer on the upper surface of a base film (not shown) on which a picture or pattern is printed. As the base film, a thermoplastic resin such as polyvinyl chloride resin or polyethylene resin, or a thin paper material can be used, with an ink-receiving layer formed on the surface. Ink is fixed to this ink-receiving layer by printing according to the application. Examples of printing methods include offset printing, letterpress printing, inkjet printing, and thermal transfer printing.

[0027] The magnetic wall 1 is constructed by laminating a wall material film 13 onto a soft magnetic board 10 via, for example, a urethane-based adhesive. The wall material film 13 is then fastened and secured to a wall substrate (not shown) made of plywood, concrete, or light metal, with the front side facing the interior space, using nails, screws, adhesive, double-sided adhesive tape, or staples.

[0028] As shown in Figures 1 to 4, the square-shaped shelf 2 has a square-shaped main body 20 having an internal space S1 in which items can be stored, a plurality of fixing plates 30 that are inserted into through holes 25 in the back plate 24 of the main body 20 to firmly fix the main body 20 to the magnetic wall 1, and a cover plate 40 that conceals the fixing plates 30 inserted into the through holes 25. The main body 20 and the fixing plates 30, and the main body 20 and the cover plate 40 can be separated and combined without tools.

[0029] The main body 20 is constructed by assembling five wooden boards in a box-like shape and joining adjacent boards together with adhesive. Specifically, the five wooden boards consist of a bottom board 21, a top board 22, a pair of side boards 23, 23, and a back board 24. The bottom board 21, the top board 22, and the pair of side boards 23, 23 each have one flat surface, but the back board 24 has horizontally elongated rectangular through holes 25, 25 of the same shape and size that penetrate in the thickness direction, on its top and bottom.

[0030] Furthermore, a magnetic sheet 51 is provided on the back side of the back panel 24, that is, the side facing the magnetic wall 1. The magnetic sheet 51 is fixed with adhesive to three locations on the top, middle, and bottom of the wooden part of the back panel 24, sandwiching the through hole 25. The sum of the magnetic force of each magnetic sheet 51 is greater than or equal to the minimum value that can hold the main body 20 without it falling off the magnetic wall 1 when magnetically attached to the magnetic wall 1, and is strong enough to be easily removed. Here, "easy magnetic force" means that the force required to detach the main body 20, which is magnetically attached to the magnetic wall 1, by pulling it in a direction perpendicular to the magnetic wall 1 and towards the front is, for example, 7 kg or less.

[0031] As shown in Figure 5, the fixing plate 30 is a block body that is square in plan view and roughly convex in side view, formed by stacking a substrate 31, an intermediate plate 32, and a magnet sheet 33 in that order, with adjacent components fixed to each other with adhesive. The substrate 31 and intermediate plate 32 are made of materials such as wood or synthetic resin. In particular, it is preferable to use a cushioning material such as urethane for the intermediate plate 32 as it provides a vibration absorption effect. The magnet sheet 33 and the intermediate plate 32 have the same size in plan view, while the substrate 31 is slightly larger than these two and has an outer edge region 311 that extends slightly outward from the intermediate plate 32. The fixing plates 30 are provided in sets of four, each of the same shape and size, for each main body 20. They are sized to allow two plates to be inserted side-by-side into the upper through-holes 25 and two plates into the lower through-holes 25 of the back plate 24.

[0032] The magnetic force of the magnetic sheet 33 is such that the main body 20 is firmly held to the magnetic wall 1 when the four fixing plates 30 are magnetically attached to the magnetic wall 1 via the back plate 24. Furthermore, the magnetic force is such that each fixing plate 30 can be removed without difficulty.

[0033] Here, we will explain the relationship between the specifications of the fixing plate 30 and the main body 20. As shown in Figure 6, the magnet sheet 33 and intermediate plate 32 of the fixed plate 30 have a front view size that allows them to be inserted into the through hole 25 of the back plate 24 in the main body 20. Furthermore, the magnetic attachment surface 331 of the magnet sheet 33 of the fixed plate 30 is on the same plane as the magnetic attachment surface 511 of the magnet sheet 51 provided on the outer surface of the back plate 24, when the inner surface 312 of the outer edge region 311 of the fixed plate 30 (the side where the magnet sheet 33 and intermediate plate 32 are located) is in contact with the inner surface 242 of the back plate 24 (the side where the magnet sheet 51 is not provided). A specific example that satisfies these conditions is when the thickness v2 of the magnet sheet 33 and the thickness v1 of the magnet sheet 51 are the same, and the thickness v3 of the intermediate plate 32 and the thickness u1 of the back plate 24 are the same. In this example, the magnet sheet 33 and the magnet sheet 51 can be cut from the same magnet sheet, which is advantageous from the viewpoint of ease of manufacture.

[0034] The above can be expressed as follows: u1+v1=v3+v2 Here, v1: Magnetic sheet thickness 51 v2: Magnetic sheet thickness 33 v3: Intermediate plate thickness 32 u1: Thickness of back panel 24 That is the case. In the favorable example above, v1=v2 and u1=v3.

[0035] This arrangement allows the magnetic sheet 33 of the fixing plate 30 inserted into the through hole 25 of the back plate 24 and the magnetic sheet 51 fixed to the main body 20 to be simultaneously magnetically attached to the magnetic wall 1. At this time, by positioning the upper outer peripheral surface 321 of the intermediate plate 32 in contact with the upper inner peripheral surface 251 of the through hole 25 of the back plate 24, the load of the main body 20 and the heavy object (not shown) stored in its internal space S1 can be supported (see Figure 6). Furthermore, the inner surface 312 of the outer edge region 311 of the fixing plate 30 comes into contact with the inner surface 242 of the back plate 24, which resists the force component acting in the forward direction of the magnetic wall 1 and restricts the movement of the main body 20 in the direction normal to the wall surface.

[0036] The lid plate 40 is intended to conceal the fixing plate 30 inserted into the through hole 25 of the back plate 24. It is made of a roughly rectangular sheet body sized to fit into the storage space S1 of the main body 20, and has a handle portion 41 on one side. The handle portion 41 is curved in a roughly U-shape in side view, continuously along that side, so that a person's fingertips can engage and grasp it. The lid plate 40 is made of a thin sheet of synthetic resin having an area equivalent to the front opening of the main body 20.

[0037] Next, the procedure for attaching the square-shaped shelf 2 to the magnetic wall 1 will be explained using Figures 7, 8, and 9. Figure 7 is a flowchart showing the procedure for attaching the square shelf 2 to the magnetic wall 1, and Figure 8 is a front view showing the procedure for attaching the square shelf 2 to the magnetic wall 1 in chronological order. Figure 9 is a diagram to explain the balance of forces acting on the magnetic wall mounting system 100, where (a) is a front view and (b) is a side cross-sectional view.

[0038] The installation of the square shelf 2 to the magnetic wall 1 involves the following steps, as shown in Figure 7: a temporary fixing step S11 of the main body 20, a confirmation step S12 of the fixing state of the main body 20, a determination step S13, a correction step S14 of the fixing state of the main body 20, a permanent fixing step S15 of the main body 20, and an installation step S16 of the cover plate 40. The contents of each step will be described below.

[0039] [Step S11: Temporarily fixing the main body] First, as shown in Figure 8(a), the main body 20 is temporarily fixed onto the magnetic wall 1. That is, the user uses both hands to grasp the left and right side plates 23, 23 of the main body 20 so that the magnetic sheet 51 is on the far side, and brings the magnetic sheet 51 close to the desired position on the magnetic wall 1. As a result, the magnetic sheet 51 adheres to the magnetic wall 1, and the main body 20 is temporarily fixed onto the magnetic wall 1.

[0040] [Step S12: Checking the fixed state of the main unit] Next, check if there are any problems with the fixing state in step S11. Specifically, check the position and orientation of the main body 20. That is, check whether it is installed in the position desired by the user and whether it is installed horizontally without tilting. The latter can be accurately checked, for example, by placing a bubble level on the top plate 22.

[0041] [Step S14 for correcting the fixed state of the main unit] If there is a problem with the fixing state (determined as "No" in judgment step 13), the fixing state of the main body 20 is corrected. When correcting, the main body 20 may be temporarily removed from the magnetic wall 1, or it may be left attached. In the former case, the user removes it and then reattaches it to the desired state. In the latter case, while the main body 20 is attached to the magnetic wall 1, translational movement in the horizontal and vertical directions, and rotational movement around an axis perpendicular to the wall surface are performed as appropriate to achieve the desired state. Here, the magnetic sheet 51 is designed to be at least the minimum strength required to hold the main body 20 from the magnetic wall 1 without it falling off while magnetically attached to the magnetic wall 1, and to be strong enough to be easily removed. Since the main body 20 is fixed to the magnetic wall 1 by such a magnetic sheet 51, it can be easily removed or moved while magnetically attached.

[0042] [Step S15 for permanently fixing the main body] Once the temporary fixing is complete (yes in step 13), the final fixing is performed using the fixing plate 30 in the order shown in Figures 8(b), (c), (d), and (e). The user grasps the outer edge region 311 of the substrate 31 on the fixing plate 30 using the thumb, index finger, and middle finger of one hand, with the magnet sheet 33 facing inwards, and inserts the magnet sheet 33 through the internal space S1 of the main body 20 into the upper through-hole 25 of the back plate 24, thereby magnetically attaching it to the magnetic wall 1. At this time, the upper outer peripheral surface 321 of the intermediate plate 32 contacts the upper inner peripheral surface 251 of the through-hole 25, thereby magnetically attaching it (see Figures 6, 8(b), and 9). Two fixing plates 30 are placed side by side in the upper through-hole 25 and magnetically attached (see Figure 8(c)). Two fixing plates 30 are placed side by side in the lower through-hole 25 in a similar manner and magnetically attached (see Figures 8(d) and (e)).

[0043] Figure 9 shows the relationship between the forces F1, F2, and W acting on the magnetic wall mounting article system 100 when the four fixing plates 30 are magnetically attached in this manner. When the weight of the main body 20 is W, the upward force acting on one magnet sheet 51 is F1, and the upward force acting on one magnet sheet 33 is F2, the following equation holds true. 3 × F1 + 4 × F2 = W In Figure 9, the numbers in parentheses represent the symbols of the components to which the force acts.

[0044] Once the main fixing is complete, the cover plate 40 is installed as shown in Figure 8(f). The user grasps the handle portion 41 of the cover plate 40 with their fingertips and pushes it into the internal space S1. In this way, the installation of the square shelf 2 to the magnetic wall 1 is completed.

[0045] Thus, when attaching the square shelf 2 to the magnetic wall 1, for example as shown in Figure 8, the main body 20 is first temporarily fixed to the magnetic wall 1 by magnetically attaching the magnetic sheet 51 of the back plate 24 to the magnetic wall 1. Next, with the upper outer peripheral surface 321 of the intermediate plate 32 of the fixing plate 30 in contact with the upper inner peripheral surface 251 of the through hole 25 of the back plate 24 from below, the magnetic sheet 33 of the fixing plate 30 is magnetically attached to the magnetic wall 1. As a result, the main body 20 receives a support force F1 from the magnetic attachment of the magnet sheet 51 and a support force F2 from the intermediate plate 32 which is magnetically attached by the magnet sheet 33, as shown in Figure 9. In other words, the magnet sheet 51 and the magnet sheet 33 share and bear the load on the main body 20.

[0046] Next, the procedure for removing the square shelf 2 from the magnetic wall 1 will be explained with reference to Figures 10 and 8. Figure 10 is a flowchart showing the procedure for removing the square shelf 2 from the magnetic wall 1. The procedure for removing the square shelf 2 from the magnetic wall 1 includes, as shown in Figure 10, a step S21 for removing the cover plate 40, a step S22 for removing the fixing plate 30, a determination step S23, and a step S24 for removing the main body. The removal procedure is basically the reverse of the installation procedure, that is, proceeding from (f) to (a) in Figure 8. The contents of each step will be explained below.

[0047] [Step S21 for removing the cover plate 40] First, remove the lid plate 40 (see Figure 8(f)). To remove the lid plate 40, insert one hand into the internal space S1 of the square shelf 2, and pull it out towards you while pinching the handle portion 41 with your fingertips.

[0048] [Step S22 for removing the fixing plate 30] Next, remove the fixing plate 30. To remove the fixing plate 30, use the thumb, index finger, and middle finger of one hand to grasp the outer edge region 311 of the substrate 31 and pull it towards you to release the magnetization of the magnetic sheet 33. Remove them one by one in the order shown in Figure 8(e), (d), (c), and (b).

[0049] [Step S24 for removing the main unit] Once all the fixing plates 30 have been removed (yes in step S23), the main body 20 is removed. That is, the user uses both hands to grasp the left and right side plates 23, 23 of the main body 20 and pulls them towards them to release the magnetization of the magnetic sheet 51. In this way, the removal of the square shelf 2 from the magnetic wall 1 is completed.

[0050] Thus, when removing the square shelf 2 from the magnetic wall 1, first the magnetic sheet 33 of the fixing plate 30 is removed from the magnetic wall 1, and then the magnetic sheet 51 of the main body 20 is removed from the magnetic wall 1. In other words, instead of removing the magnetic sheet with strong magnetic force all at once as in the conventional method, it is possible to remove the magnetic sheet with relatively weak magnetic force in multiple steps, making removal easier.

[0051] Thus, in this embodiment, the square shelf 2 can be easily removed from the magnetic wall 1, and the mounting state can be easily corrected. The reason why the upper outer surface 321 of the intermediate plate 32 in the fixing plate 30 is brought into contact with the upper inner surface 251 of the through hole 25 in the back plate 24 from below is to resist the force in the direction of gravity of the heavy object stored in the storage space S1 of the main body 20. The magnetic sheet 33 is effective in this state.

[0052] Furthermore, since the fixing plate 30 has an outer edge region 311 that extends outward from the front view of the magnet sheet 33, the inner surface 312 of the outer edge region 311 abuts against the surrounding surface 242 of the back plate 24, which can resist the force acting in the forward direction of the magnetic wall 1. Even if a large impact such as an earthquake occurs and the magnet sheet 51 is about to come off, the main body 20 can be prevented from moving in the direction normal to the wall surface of the magnetic wall 1, thus preventing it from falling off.

[0053] Furthermore, since multiple fixing plates 30 are provided for each main body 20, the magnetic force per magnet sheet 33 can be reduced, making it easier to remove the fixing plates 30. In addition, the cover plate 40 is inserted into the internal space S1 of the main body 2 and conceals the fixing plates 30, so the fixing plates 30 are not exposed, resulting in a better appearance.

[0054] [Variation] Figure 11 is an external perspective view of the modified main body 20A, where (a) shows an overall perspective view and (b) shows an exploded perspective view. In the above-described embodiment, the back plate 24 of the main body 20 was made of a single sheet of material with through holes 25 at two locations, top and bottom. However, in this modified example, three horizontally elongated rectangular plates 24A are fixed to one opening of a hollow frame 26 that is roughly "square" shaped in front view, with a predetermined distance between adjacent plates. A magnetic sheet 51 is then fixed to each of the rectangular plates 24A. In this modified example, the space 25A corresponding to the through holes 25 described in the embodiment is formed by the three rectangular plates 24A, thus eliminating the need to drill holes in the back plate 24 and reducing manufacturing costs.

[0055] While 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 modifications within the meaning and scope equivalent to the claims. In other words, the configuration, structure, shape, size, number, material, arrangement, application, etc., of each part or the entire magnetic wall mounting system 100, the box-shaped shelf 2, and the magnetic wall 1 can be appropriately modified in accordance with the spirit of the present invention. For example, while a box-shaped shelf was shown as an item to be mounted on a magnetic wall, it can also be applied to L-shaped shelves with an L-shape when viewed from the side, or picture frames with a flat frame. [Industrial applicability]

[0056] It can be widely used as a magnetic mounting type mounting item and system that can be attached to a magnetic wall by magnetic force in a detachable manner. [Explanation of Symbols]
