[0010] The present invention will be described below based on preferred embodiments with reference to Figures 1 to 7. The same or equivalent components and members shown in each drawing are given the same reference numerals, and duplicated descriptions are omitted as appropriate. The dimensions of the members in each drawing are enlarged or reduced as appropriate for ease of understanding. Some of the members that are not important for explaining the embodiments are omitted in each drawing.

[0011] (Embodiment) FIG. 1 is a perspective view showing the appearance of an assembly 100 according to an embodiment, and FIG. 2 is a side view of the assembly 100 as viewed from the direction A shown in FIG. 1. The assembly 100 includes a magnet sheet 1, a first base plate 10, a first decorative sheet 15, a second base plate 20, and a second decorative sheet 25. The assembly 100 is a laminated body formed by bonding the magnet sheet 1, the first base plate 10, the first decorative sheet 15, the second base plate 20, and the second decorative sheet 25 layer by layer with an adhesive 30. For the adhesive 30, for example, a rubber-based adhesive such as chloroprene rubber or a silicone-based adhesive is used. The adhesive 30 may also be a double-sided tape.

[0012] The assembled product 100 is, for example, approximately 8 cm long, 10 cm wide, and 1 cm thick, but the size is not limited to this. The magnetic sheet 1, the first base plate 10, and the second base plate 20 each have a thickness of approximately 2 mm to 6 mm, and may be the same or different. The assembled product 100 can be used as, for example, a souvenir or a fancy item, depending on the designs drawn on the first decorative sheet 15 and the second decorative sheet 25.

[0013] The magnet sheet 1 is a rubber magnet, and is formed into a sheet by mixing a magnetic material with rubber, for example. The assembly 100 can be detachably attached to a metal target member by adhering it to the back surface 1b of the magnet sheet 1.

[0014] The first base plate 10 is formed of a soft foamed resin material, for example, EVA resin material (ethylene vinyl acetate copolymer), urethane material, etc. The first base plate 10 is attached to the surface 1a of the magnet sheet 1 with an adhesive 30.

[0015] The first decorative sheet 15 is a transparent thin film made of polyethylene, polypropylene, or the like, and has a pattern 16 printed on its surface 15a. The pattern may be black and white or color. The first decorative sheet 15 shown in FIG. 1 has a pattern 16 of distant objects such as mountains and clouds that are visible as a background. The first decorative sheet 15 is attached to the surface 10a of the first base plate 10 with an adhesive 30.

[0016] The external shapes of the first base plate 10 and the first decorative sheet 15 in the vertical and horizontal planes are generally the same, and may be various shapes such as rectangular, elliptical, polygonal, etc., and may include any linear and curved portions. The first base plate 10 and the first decorative sheet 15 may be cut out to a specific external shape and then attached. The first base plate 10 and the first decorative sheet 15 may also be formed by attaching a large cut plate and a sheet on which a pattern 16 is printed, and then cutting them together to the specific external shape.

[0017] The second base plate 20 is formed of a soft foamed resin material, similar to the first base plate 10, such as an EVA resin material, a urethane material, etc. The second base plate 20 is attached to the surface 15a of the first decorative sheet with an adhesive 30.

[0018] The second decorative sheet 25, like the first decorative sheet 15, is a transparent thin film made of polyethylene, polypropylene, or the like, and has a pattern 26 printed on its surface 25a. The pattern may be black and white or color. The second decorative sheet 25 shown in FIG. 1 has a pattern 26 of an object such as a shrine gate, stairs, or walkway that is visually perceived to be in front of the pattern drawn on the first decorative sheet 25. The second decorative sheet 25 is attached to the surface 20a of the second base plate 20 with an adhesive 30.

[0019] The second base plate 20 and the second decorative sheet 25 have smaller outer shapes than the first base plate 10 and the first decorative sheet 15, and partially cover the surface 15a of the first decorative sheet 15. Fig. 3 is a schematic diagram showing an example of the first decorative sheet 15. The first decorative sheet 15 has a pattern 16 of mountains, clouds, etc., as described above, and also has a pattern 26 on the second decorative sheet 25 of a torii gate, stairs, etc., which are visible in the foreground. In this way, a single picture with the pattern 16 and the pattern 26 may be printed on the surface 15a of the first decorative sheet 15, and a partially extracted pattern 26 may be printed on the surface 25a of the second decorative sheet 25.

[0020] Returning to Figures 1 and 2, the external shapes of the second base plate 20 and the second decorative sheet 25 in the vertical and horizontal planes are generally the same, and may be various shapes such as rectangular, elliptical, polygonal, etc., and may include any linear and curved portions. The second base plate 20 and the second decorative sheet 25 may be cut out in a predetermined external shape and then attached. The second base plate 20 and the second decorative sheet 25 may also be formed by attaching a plate cut to a large size and a sheet on which a pattern 26 is printed, and then cutting both into the predetermined external shape.

[0021] The hardness of the magnet sheet 1 may be, for example, 50 or more and 90 or less according to a type A durometer of JIS-K6253. When a harder material is selected for the magnet sheet 1, the thickness may be reduced to facilitate bending deformation in the out-of-plane direction of the main surface. The hardness of the first base plate 10 and the second base plate 20 may be, for example, 10 or more and 50 or less according to a type C durometer of SRIS 0101, ASKER C. It is preferable that the first base plate 10 and the second base plate 20 have a smaller rigidity in bending deformation in the out-of-plane direction of the main surface than the magnet sheet 1. The first decorative sheet 15 and the second decorative sheet 25 are, for example, thin films of about 0.1 mm to 0.3 mm, and have a smaller rigidity in bending deformation in the out-of-plane direction of the main surface than the magnet sheet 1, the first base plate 10, and the second base plate 20.

[0022] Next, the operation of the assembly 100 will be described. As described above, the assembly 100 is detachably attached to a metal target member by being attracted to the back surface 1b of the magnetic sheet 1. When removing the assembly 100 from the target member, the user hooks his / her fingers on the side of the peripheral portion of the assembly 100 and applies force in a direction away from the target member.

[0023] 4(a) and 4(b) are schematic diagrams for explaining the removal of the assembly 100 from the target member 90. FIG. 4 corresponds to a side view seen from direction B in FIG. 1. Immediately after the start of removal, as shown in FIG. 4(a), a force P applied to the side surface of the peripheral portion of the assembly 100 bends and deforms the assembly 100 in the out-of-plane direction near the peripheral portion, and the peripheral portion of the assembly 100 separates from the target member 90. The applied force P need only be slightly larger than the adhesive force of the magnet sheet 1 acting near the peripheral portion of the assembly 100, and a small force can be used to lift the peripheral portion of the assembly 100 from the target member 90.

[0024] 4(b), even as removal of the assembly 100 progresses, the assembly 100 bends and deforms in the out-of-plane direction in response to the applied force P, and moves away from the target member 90, and finally the assembly 100 can be removed from the target member 90. If one were to consider removing an assembly that is layered using a hard wooden base member, the assembly would need to be removed so that it rotates like a rigid body, which would require a large force P that resists the adhesive force of the entire magnetic sheet 1.

[0025] In this way, since the first base plate 10 and the second base plate 20 are made of a soft resin material, the assembly 100 can be removed from the attachment target member 90 while bending and deforming in the out-of-plane direction of the main surface, so that the force P applied during removal can be reduced, making handling easier. Furthermore, if the assembly 100 is accidentally dropped, it will bend and deform due to the load it receives when it collides with a contact object such as a floor, absorbing the impact, thereby reducing damage to the contact object.

[0026] The hardness of the first base plate 10 and the second base plate 20 is 10 or more and 50 or less in type C durometer according to SRIS 0101, ASKER C. For example, when the outer dimensions of the assembly 100 are about 8 cm in length and 10 cm in width, and the thicknesses of the first base plate 10 and the second base plate 20 are about 2 mm to 6 mm, the assembly 100 can be removed from the attachment target member 90 without applying a large force to the fingers.

[0027] Since the first base plate 10 and the second base plate 20 of the assembly 100 are formed from a foamed resin material, unevenness in the cut surfaces caused by the cutting process (cutting with a blade, laser processing, die cutting, etc.) when cutting out the outer shape tends to be suppressed, resulting in a good finish.

[0028] The material of the first base plate 10 and the second base plate 20 of the assembly 100 may be either closed-cell or open-cell. When a closed-cell material is selected as the material of the first base plate 10 and the second base plate 20, even if the first base plate 10 and the second base plate 20 are immersed in a liquid such as water, the liquid does not penetrate the first base plate 10 and the second base plate 20, and the liquid can be removed by wiping the surface.

[0029] When an open-cell material is selected as the material for the first base plate 10 and the second base plate 20, the user can press in the first decorative sheet 15 and the second decorative sheet 25 with his or her finger or the like to create a depression therein, thereby imparting a feel that suits the user's preference.

[0030] The material of the first base plate 10 and the second base plate 20 of the assembly 100 is EVA resin, which generally makes it easier to cut and results in a better finish than rubber materials.

[0031] (Modification) Fig. 5 is a side view of an assembly 100 according to a modified example. Fig. 5 is a side view seen from the direction A in Fig. 1, similar to Fig. 2. In this modified example, the first decorative sheet 15 is formed all around the periphery to a position set back from the peripheral edge of the first base plate 10 toward the center of the surface of the first base plate 10 by a dimension S1. Dimension S1 may be, for example, about 1 to 2 mm, but is not limited to this.

[0032] When a user places his / her fingers on the side portion of the assembly 100, the first decorative sheet 15 is formed to a position that is set back from the periphery of the first base plate 10 by a dimension S1, making it difficult for the user to place the fingers on the first decorative sheet 15 and preventing the first decorative sheet 15 from peeling off from the first base plate 10.

[0033] Since the first decorative sheet 15 is formed around the entire outer shape of the first decorative sheet 15 up to a position that is set back from the periphery of the first base plate 10 by a dimension S1, no matter where a user places their fingers on the side portion of the assembly 100, it is difficult for the user to get their fingers caught on the first decorative sheet 15.

[0034] The second decorative sheet 25 is formed around the entire periphery to a position set back from the peripheral edge of the second base plate 20 by a dimension S2 toward the center of the surface of the second base plate 20. The dimension S2 may be, for example, about 1 to 2 mm, but is not limited to this.

[0035] When a user places his / her fingers on the side portion of the assembly 100, the second decorative sheet 25 is formed to a position that is set back from the periphery of the second base plate 20 by a dimension S2, making it difficult for the user to place the fingers on the second decorative sheet 25 and preventing the second decorative sheet 25 from peeling off from the second base plate 20.

[0036] Furthermore, since the second decorative sheet 25 is formed around the entire outer shape of the second decorative sheet 25 up to a position that is set back from the periphery of the second base plate 20 by a dimension S2, no matter where the user places their fingers on the side portion of the assembly 100, it is difficult for the user to get their fingers caught on the second decorative sheet 25.

[0037] Fig. 6 is a side view of an assembly 100 according to another modified example. Like Fig. 2, Fig. 6 is a side view seen from the direction A in Fig. 1. In this modified example, a soft coating layer 40 is formed on the sides of the magnet sheet 1, the first base plate 10, and the second base plate 20 of the assembly 100 so as to cover the surfaces of the first decorative sheet 15 and the second decorative sheet 25.

[0038] The coating layer 40 may be formed by applying and solidifying, for example, a transparent silicone adhesive or sealant. By using a soft material for the coating layer 40, the assembly 100 can be easily bent in the out-of-plane direction of the main surface.

[0039] FIG. 7 is a side view of an assembly 100 according to yet another modification. FIG. 7 is a side view seen from the direction A in FIG. 1, similar to FIG. 2. In this modification, a third decorative sheet 35 is attached to the surface 1a of the magnet sheet 1 of the assembly 100 with an adhesive 30, and a first base plate 10 is attached to the surface 35a of the third decorative sheet 35 with an adhesive 30. In the case of the picture shown in FIG. 1, the sky in the background is drawn on the third decorative sheet 35 so that it can be seen from the front side, mountains and clouds are drawn on the first decorative sheet 15, and torii gates, stairs, walkways, etc. are drawn on the second decorative sheet 25 so that they can be seen from the front side. This allows the assembly 100 to give a further sense of perspective to the picture drawn.

[0040] The above description is based on the embodiment of the present invention. These embodiments are merely examples, and it is understood by those skilled in the art that various modifications and changes are possible within the scope of the utility model registration claims of the present invention, and that such modifications and changes are also within the scope of the utility model registration claims of the present invention.
