[0004] However, when a display such as a piece of paper is attached to the surface of a magnetic sheet with cellophane tape, there is a problem in that the display may be damaged by wind and rain. Furthermore, when a slit is formed on the display surface to allow a display object to be inserted therein, it is necessary to apply a covering layer such as cellophane tape to the back of the magnetic sheet to cover the slit, which is time-consuming. Furthermore, there is also the problem that the cutouts may be lifted by wind pressure during travel, impairing the smoothness of the display surface, and that rainwater and dust may seep in through the cutouts, soiling the displayed items inside. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention was developed in consideration of these problems, and aims to provide an improved version of the conventional magnetic sheet, a laminated flexible display body that can be attached and detached easily to the metal surface of a vehicle body, etc., and that can waterproofly protect displayed items when stored inside without any hassle. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below are merely examples, and the present invention is not limited to the configurations described in the embodiments.

[0010] 1 is a front view showing one embodiment of a laminated flexible display body 100. The laminated flexible display body 100 has a slit section 2 and includes a base layer 10, a display layer 20, a protective layer 40, a variable advertisement section 50, and a fixed advertisement section 60.

[0011] The slit portion 2 refers to a thin cut or gap that penetrates vertically from one side of the base material layer 10 to the other side, or from the display layer 20 provided on one side of the base material layer 10 to the other side of the base material layer 10. The slit portion 2 allows the part of the laminated flexible display 100 covered with the protective layer 40 to move locally, allowing opening and closing, lifting, replacement of the display object 1, etc.

[0012] The substrate layer 10 is a plastic substrate formed by molding and / or cutting a plastic base product whose main component is an artificial polymer material such as plastic, and contains a magnetic material. Examples of plastic base products include films, sheets, plates, molded bodies, and composite laminates. The plastic substrate is formed by molding and / or cutting a plastic base product, and performs specific functions such as mechanical support, decoration, protection, display, and adhesion. The laminated flexible display 100 has a sheet-like substrate layer 10 that is attached to a metal surface by the magnetic material and can be easily reattached. In the laminated flexible display 100 of this embodiment, the surface area of ​​the substrate layer 10 is larger than that of the protective layer 40.

[0013] The display layer 20 is provided on one side of the base layer 10 and displays visual information such as designs, letters, symbols, etc. In this embodiment, the display layer 20 is provided on the base layer 10 except for the edge portions. The display layer 20 may be provided on the entire surface of the base layer 10, or may be provided on the variable advertisement section 50 and the fixed advertisement section 60, or may be provided only on the fixed advertisement section 60, or may be provided on some or all of these sections.

[0014] The protective layer 40 is provided on one side of the base layer 10 and encompasses the slit portion 2, with a peripheral portion 5 attached to the base layer 10. The peripheral portion 5 widely surrounds the outer periphery of the slit portion 2 and includes the edge portion of the protective layer 40. The slit portion 2 is covered in the internal space surrounded by the peripheral portion 5. The protective layer 40 has extremely high transmittance as a material through which light passes, and has the property of being able to see through the material to the other side.

[0015] The protective layer 40 may include the slit portion 2, and the peripheral portion 5 may be attached to the display layer 20. For example, the protective layer 40 may be attached to the display layer 20 at the peripheral portion 5 by an adhesive layer including a pressure-sensitive adhesive layer (not shown), or may be attached using a high-frequency welder. That is, attachment includes bonding using a high-frequency welder and bonding using an adhesive layer. In this case, the protective layer 40 also serves as both a waterproof layer and a protective layer.

[0016] The variable advertising unit 50 is the area covered by the protective layer 40, excluding the peripheral portion 5. The variable advertising unit 50 is provided on the base material layer 10 or the display layer 20 within the area surrounded by the peripheral portion 5, and is visible through the protective layer 40. The variable advertising unit 50 also serves as an internal space capable of storing display items 1 such as paper media or advertising cards, and display members such as tags. When the display layer 20 is provided in the area covered by the protective layer 40, the combination of the display layer 20 and the display item 1 in this area, and the display of the display layer 20 of the variable advertising unit 50, can be changed and displayed. When the display layer 20 is not provided in the area covered by the protective layer 40, the combination of the base material layer 10 and the display item 1 in this area, and the base material layer 10 of the variable advertising unit 50 can be changed and displayed.

[0017] The fixed advertisement section 60 is a part of the display layer 20 and the edge of the base material layer 10, or a part of the display layer 20, in the area not covered by the protective layer 40 when viewed from the front. The fixed advertisement section 60 is provided outside the peripheral edge section 5. More specifically, the fixed advertisement section 60 is provided in the area between the peripheral edge section 5 and the end of the base material layer 10, and is visible without the protective layer 40 in between.

[0018] Fig. 2 is a rear view showing the laminated flexible display body 100. The laminated flexible display body 100 has a flat magnetic portion 30. As shown in Fig. 2, the flat magnetic portion 30 is provided on the other surface side of the base material layer 10. In the flat magnetic portion 30, the slit portion 2 is formed at a predetermined distance L from the end of the base material layer 10, and the other surface side of the base material layer 10 in the peripheral region 3 of the slit portion 2 is flat.

[0019] The flat magnetic portion 30 has a predetermined distance L from the end of the base layer 10 to the slit portion 2, a peripheral area 3 of the slit portion 2 that is flat, and at least the area surrounded by the three edges of the base layer 10 and the slit portion 2, as shown in FIG. 2 . The distance L is sufficiently longer than the short length of the slit portion 2, and preferably extends from 20 mm to 100 mm around the slit portion 2. The distance L is measured using a JIS B 7507:2016 vernier caliper. If the distance L is less than 20 mm, waterproofing may be impaired. If the distance L is greater than 100 mm, a display object 1 with a length of 420 mm, such as an election poster, may not be able to be stored in a vehicle with a door width of 580 mm. The flat magnetic portion 30 has a predetermined distance L in at least three directions from the slit portion 2 to the nearby edge, and its area includes the product of the distance L and the sum of twice the length L and the long length of the slit portion 2.

[0020] FIG. 3 is an enlarged schematic diagram showing the cross-sectional configuration of a fixed advertising portion 60 in the peripheral region 3 of a laminated flexible display body 100 detachably attached to a metal substrate S. More specifically, FIG. 3 is a schematic enlarged cross-section of the peripheral region 3 on the outer periphery of the peripheral edge portion 5 cut in the longitudinal direction and viewed toward the inner periphery. The laminated flexible display body 100 is a display medium constructed by laminating multiple layers, and is detachably attached to a metal substrate S. The laminated flexible display body 100 is three-dimensional and extremely thin.

[0021] The base layer 10 is formed by adding a magnetic material to a flexible plastic film, sheet, plate, molded body, or composite laminate material. Examples of such materials include soft polyvinyl chloride (PVC), polyester (PET), polypropylene (PP), and thermoplastic polyurethane (TPU). The base layer 10 provides flexibility, weather resistance, and magnetic properties.

[0022] The display layer 20 has a printing layer 120, which displays information such as advertisements, guidance, and signs. The printing layer 120 includes ink layers 121 and 122 formed by UV printing, inkjet printing, or the like, and in this embodiment, displays advertising information including fixed advertisements. Note that the display layer 20 may have a configuration in which the printing layer 120 is a solid ink layer, with a synthetic resin sheet provided thereon.

[0023] 3, the printed layer 120 may include a first ink layer 121 and a second ink layer 122, with the first ink layer 121 being a single color such as yellow, fluorescent, white, or black, and the second ink layer 122 being multicolored, including transparent colors. In this case, the first ink layer 121 may be an undercoat layer for the second ink layer 122, and the second ink layer 122 may represent visual information such as figures, designs, letters, or symbols. The printed layer 120 may be composed only of the first ink layer 121 or the second ink layer 122, or may include layers other than these.

[0024] The flat magnetic portion 30 shown in Fig. 3 is present in a peripheral region 3 having a predetermined distance L around the slit portion 2. The flat magnetic portion 30 may be configured to maintain the magnetic state of the metal substrate S in the peripheral region 3 of the slit portion 2, and also to have a portion that doubles as a grip when attaching or detaching. In this case, by lifting the edge of the flat magnetic portion 30, air enters between the metal substrate S and the flat magnetic portion 30, causing the flat magnetic portion 30 to bend as if bent at the slit portion 2, allowing the user to easily grip the flat magnetic portion 30 when attaching or detaching, making it easy to insert or remove the display object 1.

[0025] The protective layer 40 is intended to protect the displayed information, maintain visibility, or improve adhesion durability. An example of the protective layer 40 is a transparent film. Specifically, the transparent film is preferably made of a resin such as polyester (PET), polycarbonate (PC), polyurethane (PU), polyvinyl chloride (PVC), or acrylic resin.

[0026] In this embodiment, the protective layer 40 is made of a flexible, transparent material such as polyester (PET) or soft polyvinyl chloride (PVC). The thickness of the protective layer 40 is preferably, for example, approximately 50 to 200 μm. The protective layer 40 is disposed above the variable advertisement section 50 in the peripheral region 3 of the slit section 2 to ensure visibility as well as provide waterproofing and protection. On the other hand, the fixed advertisement section 60 is not covered with the protective layer 40, and the printed layer 120 is exposed. Note that, although the printed layer 120 in the peripheral region 3 is exposed in FIG. 3, the protective layer 40 may be provided on the ink layers 121 and 122 in the peripheral region 3.

[0027] Fig. 4 is an enlarged schematic diagram showing the cross-sectional configuration of the variable advertisement section 50 in the peripheral area 3. More specifically, Fig. 4 shows a schematic enlarged cross section of the peripheral area 3 on the inner periphery of the rim 5, cut longitudinally and viewed from the outer periphery. In the variable advertisement section 50 in the peripheral area 3, the protective layer 40 is provided above the ink layers 121, 122, allowing the display object 1 to be inserted and removed, and allowing the display of variations in the combination of the display object 1 and the ink layers 121, 122 to be switched.

[0028] The manufacturing method of the laminated flexible display body 100 of this embodiment is as follows: First, a plastic base material is molded and / or cut to form a flexible plastic substrate, and a magnetic material is integrated onto this plastic substrate to form a sheet-like substrate layer 10 containing the magnetic material on the plastic substrate.

[0029] Next, a display layer 20 that displays visual information such as designs, letters, symbols, etc. is provided on one side of the base layer 10. Here, the base layer 10 provided with the display layer 20 may be cut to a predetermined size. Furthermore, a slit portion 2 is formed a predetermined distance L away from the end of the base layer 10, and the other side of the base layer 10 is configured to include a flat magnetic portion 30 in the peripheral region 3 without adhering a covering layer such as cellophane tape to the slit portion 2.

[0030] Finally, the protective layer 40 is placed on top of the display layer 20 to cover the slit portion 2, and the peripheral portion 5 of the protective layer 40 is attached to the display layer 20 or the base material layer 10 on one side of the base material layer 10 using, for example, a high-frequency welder, thereby providing the protective layer 40 on one side of the base material layer 10.

[0031] The method for installing the laminated flexible display body 100 of this embodiment is as follows. First, the installer lifts the edge portion of the peripheral region 3. Here, the flat magnetic portion 30 flexes as if bent at the slit portion 2. Next, the installer places the display object 1 through the slit portion 2 into the internal space surrounded by the peripheral portion 5 of the protective layer 40. Finally, the installer lightly places the laminated flexible display body 100 on the metal substrate S and gently presses the laminated flexible display body 100, including the peripheral region 3, from above. Note that if it is desired to replace the previously installed display object 1, the display object 1 can be removed first and then inserted. The display object 1 is removed by lifting the edge portion of the peripheral region 3 and removing the display object 1 through the slit portion 2.

[0032] As described above, the laminated flexible display body 100 of this embodiment has the above-mentioned configuration, and is easily attachable to and detachable from a metal surface of a vehicle body, etc., and can easily and waterproofly protect the display object 1 when housed inside. In other words, the laminated flexible display body 100 of this embodiment has waterproofness, dustproofness, replaceability of the display object 1, designability, visibility, and durability, and can also improve work efficiency.

[0033] More specifically, according to the laminated flexible display 100 of this embodiment, the protective layer 40 hermetically covers the slit portion 2, preventing rainwater and dust from entering and providing excellent protection for the display object 1 inside.

[0034] Furthermore, the laminated flexible display body 100 of this embodiment has excellent reusability, as advertising papers and display cards can be easily inserted and replaced through the slit portion 2. Furthermore, the protective layer 40 smoothes the surface, allowing the display content to be clearly visible.

[0035] Furthermore, the laminated flexible display 100 of this embodiment can prevent peeling or lifting due to wind pressure or vibration, and can maintain a stable magnetic and / or adhesive state for a long period of time. The laminated flexible display 100 of this embodiment has a detachable structure using a magnet, so it can be easily removed from the vehicle and replaced.

[0036] Furthermore, with the laminated flexible display body 100 of this embodiment, installation and replacement of the display object 1 can be performed without attaching or detaching a covering layer such as cellophane tape to the slit portion 2. Furthermore, when a user lightly presses the laminated flexible display body 100 including the peripheral region 3 from above, the air is released between the metal adherend S and the flat magnetic portion 30, and the flat magnetic portion 30 maintains the magnetic state of the peripheral region 3, thereby maintaining airtightness.

[0037] Next, a stacked flexible display body according to another embodiment will be described. In this embodiment, the same or corresponding parts as those of the stacked flexible display body 100 according to the above embodiment will be denoted by the same reference numerals, and a description thereof will be omitted, and only different parts will be described.

[0038] 5 is an enlarged schematic view showing the cross-sectional structure of another embodiment of the peripheral region 3. The laminated flexible display body of this embodiment differs from the laminated flexible display body 100 in the base material layer 210 and the display layer 220.

[0039] The base layer 210 includes a magnetic layer 211 and a synthetic resin layer 212. The magnetic layer 211 is a magnetic layer in which ferrite powder or rare earth magnet powder is dispersed in resin, allowing it to be attached to and detached from a metal surface. The synthetic resin layer 212 may be a film, sheet, plate, molded body, or composite laminate made of a material such as soft polyvinyl chloride (PVC), polyester (PET), polypropylene (PP), or thermoplastic polyurethane (TPU). The synthetic resin layer 212 provides flexibility and weather resistance.

[0040] The display layer 220 includes a synthetic resin sheet 222, and specifically, may be a synthetic resin sheet or film such as polyvinyl chloride (PVC) with adhesive 221 on the backside. The display layer 220 is formed by cutting out letters, logos, and illustrations from a synthetic resin sheet or film with a mount and pasting them onto the synthetic resin layer 212 with adhesive 221.

[0041] In this embodiment, the base material layer 210 and the protective layer 40 are joined at the peripheral edge portion 5 by a high-frequency welder, and the protective layer 40 serves both waterproofing and protection. Note that the base material layer 210 and the protective layer 40 may be joined by an adhesive layer including a pressure-sensitive adhesive layer (not shown), which serves both waterproofing and protection. That is, bonding includes bonding by a high-frequency welder and bonding by an adhesive layer.

[0042] The manufacturing method of the laminated flexible display member of this embodiment is as follows: First, a plastic base product is molded and / or cut to form a flexible plastic substrate, and a synthetic resin layer 212 is formed. Next, a magnetic layer 211 is integrated with this synthetic resin layer 212 to form a sheet-like substrate layer 210 containing a magnetic material in the plastic substrate.

[0043] Next, a slit portion 2 is formed a predetermined distance L away from the end of the base material layer 210, and a flat magnetic portion 30 is formed in the peripheral region 3, with the other surface of the base material layer 210 being flat, without adhering a covering layer such as cellophane tape to the slit portion 2. Furthermore, for example, a high-frequency welder is used to adhere the peripheral portion 5 of the protective layer 40 to the synthetic resin layer 212 on one surface of the base material layer 210, thereby providing the protective layer 40 on one surface of the base material layer 210. Finally, a display layer 220 for displaying visual information such as designs, letters, symbols, etc. is provided on one surface of the base material layer 210.

[0044] The laminated flexible display of this embodiment further has properties that make it resistant to deformation, discoloration, deterioration, and other changes in quality, adhesiveness, weather resistance, and a wide variety of designs, thereby improving workability. Furthermore, when the display layer 220 is configured using a synthetic resin sheet 222 for outdoor use, it can withstand long-term use.

[0045] The configuration of the laminated flexible display body is not limited to the above embodiment, and the configurations relating to the shapes and structures of the base layer, display layer, protective layer, slit portion, flat magnetic portion, variable advertising portion, and fixed advertising portion can be modified as appropriate within the scope of the present invention.

[0046] For example, the protective layer may also function as a top coat layer that provides weather resistance and scratch resistance.Furthermore, the protective layer may be configured by combining the elements of the above-described embodiments.
