Description

[Technical Field]

[0001] The present invention relates to a sign device, more specifically to a sign device having information displayed on the side of a substantially conical main body, suitable for use as POP advertising, displays, guides, safety signs, etc. in a variety of locations, such as stores, counters, exhibition halls, museums, facilities, and roads. [Background technology]

[0002] An example of such a sign device is a traffic cone disclosed in Patent Document 1. This traffic cone has a removable cover that covers the surface of the cone. The cover is cylindrical with openings of different sizes at both ends and is made of flexible polyvinyl chloride. By placing this cover over the traffic cone, the cone is covered except for the tip. Information such as "No Entry" or "No Parking" can be written on this cover, and a cover with a guide sign appropriate for the purpose or use can be selected and placed over the cone. This means that the traffic cone itself only requires one type of sign, and no information can be written directly on the cone itself (the cone). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2001-164527 A DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0004] However, because the cover is fixed to the cone-shaped part, it requires a large area and has a lot of unnecessary space, i.e., a lot of blank space other than the display content, resulting in a lot of waste. This leads to increased product costs. Also, because there is only one cover, it is not flexible enough to add display content later.

[0005] The present invention was made with the above-mentioned circumstances in mind, and its objective is to provide a sign device that has little white space in the display area, can reduce material costs, and is highly flexible, allowing for easy addition of display content. [Means for solving the problem]

[0006] The present invention takes the following measures to solve the above problems. Note that the reference symbols in parentheses attached to each component means in this section (the "Means for Solving the Problems" section) are for reference purposes only to show the correspondence with the specific means described in the embodiments described below, and do not limit the components of the present invention to these.

[0007] In one aspect of the present invention, a sign fixture (1) has display information (43) on the side of a main body (2) that is erected in an approximately conical shape, and includes the approximately conical main body (2), a base sheet (3) provided on the side of the main body (2), and a media sheet (4) that is detachably fixed to the front side of the base sheet (3) by magnetic attraction, and both the base sheet (3) and the media sheet (4) include ferromagnetic sheets (31, 41) as base materials, and at least one of them includes a magnet sheet (41) that is a mixture of hard magnetic material powder and elastomer that has been multi-pole magnetized, and display information (43) including at least one of letters, symbols, pictures, and designs is provided on the surface of the media sheet (4) opposite to the surface facing the base sheet (3). The term "ferromagnetic sheet" includes both a magnetic sheet that exhibits the properties of a permanent magnet and a soft magnetic sheet that does not itself exhibit the properties of a permanent magnet but magnetically attracts magnetic materials such as iron.

[0008] In another aspect of the present invention, the base sheet (3) has a generally fan-shaped configuration that can be wound around the side of the main body (2), and is provided with connecting portions (33, 34, 51, 52) at both ends in the circumferential direction (D1) that connect the ends together.

[0009] In another aspect of the present invention, the connecting portions at both ends consist of a pair of connecting magnet sheets (51, 52) arranged so that the directions (Q1, Q2) in which the magnetic poles (511, 512, 521, 522) extend are perpendicular to the circumferential direction (D1) of the base sheet (3).

[0010] In another aspect of the present invention, at least one of the pair of connecting magnet sheets (51, 52) is supported rotatably about an axis (J2) normal to the surfaces of the connecting magnet sheets (51, 52). [Effects of the Invention]

[0011] According to the present invention, a sign device is provided which has little blank space other than the display area, which reduces production costs, and which is highly versatile as display content can be easily added. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. Fig. 1 is a perspective view showing the appearance of a pop cone according to the present invention, and Fig. 2 is a side view showing the laminated structure of the base sheet.

Fig. 6 is a diagram for explaining the magnetic pole structure of the magnet sheet, where (a) is a front view and (b) is a side view (viewed from direction C in (a)). Note that the scales and angles of components and the like shown in the accompanying drawings do not necessarily correspond to the actual objects, but have been adjusted appropriately to make them easier to understand. Furthermore, in this specification, "~" is used to mean that the numerical values ​​before and after it are included as lower and upper limits. Furthermore, in the following explanation, magnetic attraction may be referred to simply as magnetic adhesion.

[0014] As shown in FIG. 1, a pop cone 1 has a main body 2, a base sheet 3, and a media sheet 4, and is placed, for example, at the front of a store.

[0015] The main body 2 comprises a base 21 and an approximately conical body 22. The base 21 is made of an annular plate with an opening in the center. The approximately conical body 22 is made of a hollow cone with a tapered tip that is provided integrally with and concentric with the base above the base 21. Both the base 21 and the approximately conical body 22 are made of hard members made of synthetic resin such as plastic.

[0016] The base sheet 3 is a single, roughly fan-shaped ferromagnetic sheet that can be wound around the roughly conical body 22 of the main body 2, and is configured by laminating a covering film 32 onto a flexible soft magnetic sheet 31 with, for example, a urethane adhesive, as shown in Fig. 2. The total thickness is, for example, about 0.2 mm to 1.5 mm, and as shown in Fig. 3(a), one of the two circumferential ends of the roughly fan-shaped sheet has three elongated holes 33 drilled at equal intervals in the radial direction, and the other end has three hooks 34 lined up at equal intervals in the radial direction and protruding outward in the circumferential direction.

[0017] The soft magnetic sheet 31 does not itself have the properties of a permanent magnet, but is a sheet to which a magnet can be attracted. It is made by forming a mixture of fine powder of soft magnetic material and a small amount of organic polymer elastomer, which acts as a binder, into a sheet using a forming method such as rolling or extrusion.

[0018] As the soft magnetic material powder, a ferromagnetic material with low coercivity and high magnetic permeability (hereinafter referred to as "ferromagnetic powder"), a ferromagnetic material with low coercivity and high magnetic permeability (hereinafter referred to as "ferrimagnetic powder"), or a mixture of ferromagnetic and ferrimagnetic powders can be used. As the ferromagnetic powder, iron powder, magnetic stainless steel powder, sendust powder, etc. can be used. As the ferrimagnetic powder, soft ferrites such as manganese zinc ferrite powder, nickel zinc ferrite powder, and magnetite powder (iron oxide powder) can be used.

[0019] Examples of organic polymer elastomers that can be used as binders include chlorinated polyethylene, chlorosulfonated polyethylene, ethylene-vinyl acetate copolymer, ethylene-propylene rubber, nitrile rubber, acrylic rubber, and chloroprene rubber.

[0020] The mounting film 32 is a film-like decorative wall material, consisting of a base film 321 and an ink-receiving layer 322 on which a design or pattern is printed. The base film 321 can be made of a thermoplastic resin, such as polyvinyl chloride resin or polyethylene resin, or thin coated paper, with an ink-receiving layer formed on its surface. Ink is then fixed to the ink-receiving layer 322 by printing according to the application. Printing methods include offset printing, relief printing, inkjet printing, and thermal transfer printing. If the display film 32 is too thick, it will not be flexible enough when combined with the soft magnetic sheet 31. Furthermore, when the media sheet 4 (described below) is magnetically attached to the surface, the media sheet 4 will have a low transmittance of magnetic lines from the magnet sheet 41, resulting in poor magnetic adsorption. Furthermore, if the display film 32 is too thin, it will not be able to maintain adequate tensile strength and conceal the underlying soft magnetic sheet 31. The soft magnetic sheet 31 is generally black, and if the only purpose is to conceal it, there is no need to provide an ink-receiving layer or printing.

[0021] The three elongated holes 33 and three hook portions 34 in the base sheet 3 function as connectors connecting the ends. That is, as shown in FIG. 3(b), the base sheet 3 is wound around the central axis J1, and then the hook portions 34 are inserted into the elongated holes 33 and dropped downward to connect the ends. This forms a cylindrical body 3A having openings of different sizes at the top and bottom, as shown in FIG. 3(c). This cylindrical body 3A is sized to cover the approximately conical body 22 in the main body 2, leaving a portion of the top of the approximately conical body 22 exposed.

[0022] The media sheet 4 is an oval or rectangular sheet that can be detachably fixed to the base sheet 3 wrapped around the main body 2, and is configured by laminating a cover film 42 onto a magnetic sheet 41 with, for example, a urethane adhesive, as shown in FIG. 4. The total thickness is, for example, about 0.2 mm to 3 mm. Display information 43 is then provided on the surface of the cover film 42, as shown in FIGS. 1 and 5. In this example, the display information 43 is "SALE" and "April 5th."

[0023] The magnet sheet 41 is produced by forming a mixture of fine powder of hard magnetic material and a small amount of organic polymer elastomer as a binder into a sheet using a molding method such as rolling or extrusion, and then magnetizing both sides of the sheet.

[0024] As the hard magnetic material, ferrite-based magnetic materials such as barium ferrite and strontium ferrite, or rare earth magnetic materials such as samarium-cobalt-based magnets and neodymium-iron-boron-based magnets can be used. As with the soft magnetic sheet 31, the organic polymer elastomer may be chlorinated polyethylene, chlorosulfonated polyethylene, ethylene-vinyl acetate copolymer, ethylene-propylene rubber, nitrile rubber, acrylic rubber, chloroprene rubber, or the like.

[0025] The surface of magnet sheet 41 is formed with a multi-pole magnetization pattern in the form of parallel stripes, in which band-like N and S poles appear alternately. That is, as shown in Fig. 6, magnetic poles of constant width (N poles 411 and S poles 412) of mutually different polarities are formed alternately in stripes at equal intervals on both the front and back surfaces, forming a multi-pole magnetized type with magnetization lines 413 of a constant pitch width P. Here, magnetization line 413 refers to the imaginary boundary line between any one magnetic pole 411 on the surface of multi-pole magnetized magnet sheet 41 and the adjacent magnetic pole 412 of the opposite polarity.

[0026] In reality, this is the area that appears white when a magnetic viewer sheet (a film in which magnetic fluid microcapsules are uniformly dispersed) is attached, and is an area where the magnetic field in the normal direction to the surface of magnet sheet 41, i.e., the direction perpendicular to the surface, is extremely weak or zero. In other words, magnetization lines 413 are imaginary lines on the sheet surface. In the side view of Figure 6(b), magnetization lines 413 are located at both ends in the thickness direction of magnet sheet 41. The pitch width P of magnetization lines 413, i.e., the distance between adjacent magnetization lines 413, is 1.5 to 5.0 mm.

[0027] It is preferable that the magnet sheet 41 be made of an anisotropic material rather than an isotropic material, because an anisotropic material has stronger magnetization in the direction perpendicular to the surface of the sheet than an isotropic material, allowing the magnetic attraction effect to be maximized.

[0028] The mounting film 42 is a film-like decorative wall material, similar to the mounting film 32 in the base sheet 3, and has an ink-receiving layer 422 on the upper surface of a base film 421. The base film 421 can be made of a thermoplastic resin such as polyvinyl chloride resin or polyethylene resin, or thin coated paper, with an ink-receiving layer 422 formed on its surface. Ink is fixed to this ink-receiving layer 422 by printing according to the application. Printing methods include offset printing, relief printing, inkjet printing, and thermal transfer printing. Display information 43 is printed on the ink-receiving layer 422.

[0029] The POP cone 1 comprising the above components is used as follows. First, as shown in Figure 3(b), the base sheet 3 is wound around the central axis J1 so that the upper and lower ends of both sides are aligned. Next, the hook portions 34 on both ends are inserted into the elongated holes 33 at the same height and dropped downward to connect the ends, forming the cylindrical body 3A shown in Figure 3(c). Next, the approximately conical body 22 of the erected POP cone 1 is covered with the larger-diameter opening facing downward. Next, the media sheet 4 is magnetically attached to the surface of the covered base sheet 3 in a location appropriate for display. It is also possible to overlap one or more other media sheets on the surface of the magnetically bonded media sheet 4. It is also possible to attach one or more other media sheets to a location different from the magnetically bonded media sheet 4.

[0030] In this way, in the pop cone 1, the media sheet 4 bearing the display information 43 can be magnetically attached and fixed to any position on the base sheet 3. As the media sheet 4 only needs to occupy the area required for the display information 43, there is little blank space for the display, which reduces material costs. Furthermore, the media sheet 4 is detachable by magnetic force, and multiple media sheets 4 can be magnetically attached side by side or stacked, making it easy to add or change the display content and providing excellent versatility.

[0031] [First modified example of base sheet] Fig. 7 shows a first modified example of the base sheet in the POP cone 1, where (a) is a developed view, (b) is a perspective view when rolled up, and (c) is a perspective view when rolled up and both ends are connected. Fig. 8 shows the connection part when both ends of the base sheet of the first modified example are connected, where (a) is a bottom view (viewed in the Z1 direction in Fig. 7(c)), and (b) is a view seen from the arrow K1-K1 in (a).

[0032] In the first modified example, the connecting portions at both ends of the base sheet 3 are different from those in Fig. 3. That is, instead of the three elongated holes 33 and three hook portions 34, a first magnet sheet 51 and a second magnet sheet 52 are provided, as shown in Fig. 7. The first magnet sheet 51 and the second magnet sheet 52 are arranged so that the directions Q1 and Q2 in which the magnetic poles 511, 512, 521, and 522, respectively, extend are perpendicular to the circumferential direction D1 of the base sheet 3. Specifically, the first magnet sheet 51 is fixed to the back surface of the soft magnetic sheet 31 via an adhesive so that the magnetization pitch direction P1 is parallel to the circumferential direction D1 of the base sheet 3, and the second magnet sheet 52 is fixed to the front surface of the mounting film 32 via an adhesive so that the magnetization pitch direction P2 is parallel to the circumferential direction D1 of the base sheet 3.

[0033] The winding direction is considered to be approximately the same as the circumferential direction D1 of the base sheet 3. According to the present modification 1, when the base sheet 3 is wound around the cylindrical body 3A and stacked, the magnetic pole 511 (north pole) of the first magnet sheet 51 and the magnetic pole 522 (south pole) of the second magnet sheet 52 are magnetically attracted to each other, and the magnetic pole 512 (south pole) of the first magnet sheet 51 and the magnetic pole 521 (north pole) of the second magnet sheet 52 are magnetically attracted to each other, thereby suppressing slippage of the base sheet 3 in the circumferential direction D1 and achieving a strong connection. At this time, the magnetization line 513 of the first magnet sheet 51 and the magnetization line 523 of the second magnet sheet 52 overlap each other.

[0034] [Second modified example of base sheet] Figure 9 shows a second modified example of the base sheet in POP cone 1, where (a) is an unfolded view, (b) is an oblique view when both ends are connected without using the rotation function around the normal axis J2, and (c) is an oblique view when both ends are connected using the rotation function around the normal axis J2.

[0035] In the second modified example, at least one of the first magnet sheet 51 and the second magnet sheet 52 in the first modified example is pivotally supported so as to be rotatable about an axis J2 normal to the magnet sheet surface. Examples of the pivotal support member include a flat bolt and nut, or a pair of male and female hook members. The position of the normal axis J2 is set to the center of the length and width of the first magnet sheet 51 and / or the second magnet sheet 52, for example. In the second modification, the first magnet sheet 51 and the second magnet sheet 52, which are magnetically attached with magnetic poles of opposite polarity to each other, can change the relative angle they form with the soft magnetic sheet 31 on the rotating side. This allows the sizes of the upper and lower large and small openings to be changed, as shown in Figure 9(c), making it possible to adapt to main body parts with different degrees of tapering.

[0036] Although the embodiments of the present invention have been described above, the embodiments disclosed above are merely examples, and the scope of the present invention is not limited to these embodiments. The scope of the present invention is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0037] For example, in the above-described embodiment, a sheet including a soft magnetic sheet is used as the base sheet 3, and a sheet including a magnet sheet is used as the media sheet 4, but a sheet including a magnet sheet may be used as the base sheet 3, and a sheet including a soft magnetic sheet may be used as the media sheet 4. Furthermore, sheets including a magnet sheet may be used for both the base sheet 3 and the media sheet 4.

[0038] Furthermore, although specific characters are shown as the display information 43, it may also be symbols, pictures, patterns, or a combination thereof. Furthermore, the base sheet 3 is a laminate of the soft magnetic sheet 31 and the mounting film 32, but the mounting film 32 may be coated with soft magnetic powder. The media sheet 4 is a laminate of the magnet sheet 41 and the mounting film 42, but the mounting film 42 may be coated with hard magnetic powder and then magnetized. Furthermore, the soft magnetic sheet 31 in the base sheet 3 may be made of steel foil or magnetic stainless steel (SUS430 or the like) having a thickness of 80 μm to 200 μm. Additionally, the configuration, structure, shape, dimensions, number, arrangement, material, and the like of each part or the entirety of POP cone 1 can be modified as appropriate in accordance with the spirit of the present invention. [Industrial Applicability]

[0039] It can be widely used as a signage device suitable for use in a variety of places such as stores, counters, exhibition halls, museums, facilities, and on the streets, as POP advertising, displays, guidance, or safety signs. [Explanation of symbols]
