Description

[Technical Field]

[0001] The present invention relates to a magnetic adhesive device having a thin magnetic adhesive sheet portion having a magnetic sheet layer. [Background technology]

[0002] Magnetic sheets are made by mixing magnetic powder with rubber or resin, forming them into a sheet, and magnetizing them. They are lightweight, thin, and flexible, and can be easily attached to and detached from ferromagnetic materials such as iron. For this reason, they are widely used to post notices on objects that can be attached to magnetic sheets, such as ferromagnetic whiteboards and metal panels (see, for example, Patent Document 1).

[0003] However, conventional magnetic sheets have the problem that it is cumbersome to use both hands when sandwiching a notice between the magnetic sheet and the object to which it is attached, and when removing the notice from between the magnetic sheet and the object to which it is attached. For example, when sandwiching a notice between the magnetic sheet and the object to which it is attached, it is necessary to hold the notice with one hand and attach and fix the magnetic sheet with the other hand, and when removing the notice, it is necessary to hold the notice with one hand and remove the magnetic sheet with the other hand.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 9-24573 Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been made in light of the above problem, and aims to provide a magnetic adhesive device that allows posters to be easily posted and removed. [Means for solving the problem]

[0006] The magnetic adhesive device of the present invention comprises a thin magnetic adhesive sheet portion having a magnetic sheet layer, and a film portion provided on at least the adhesive surface of the magnetic adhesive sheet portion so as to protrude from at least a part of the inner edge to the outer edge. [Effects of the Invention]

[0007] According to the present invention, at least the attachment surface of the magnetic adhesive sheet is provided with a film portion that protrudes from at least a portion of the inner edge to the outer edge. This allows the outer edge of the film portion to function like a shoehorn to facilitate the insertion of a notice, and the film portion covers the corners of the attachment surface of the magnetic adhesive sheet, preventing the notice from getting caught on the corners. Therefore, when posting a notice, the magnetic attachment device is attached to the target object, and the notice can be easily inserted by holding the notice with one hand and sliding the notice between the magnetic attachment device and the target object from the side with the film portion. Furthermore, when removing the notice, the notice can be easily removed by holding the notice with the other hand and pulling it out from between the magnetic attachment device and the target object.

[0008] Therefore, posters can be easily posted or removed with one hand, and the time and effort of attaching and removing the magnetic attachment device each time a poster is posted or removed can be eliminated. When replacing a poster, the magnetic attachment device remains in place after the previous poster is removed, so the next poster can be inserted and used immediately.

[0009] Furthermore, when removing the magnetic attachment device from the attachment target, it can be easily removed by pinching the outer edge of the film part with your hands. Furthermore, when storing, it can be stuck on one side in a corner, so it can be stored in a small space. In addition, even if the magnetic attachment device falls, it will not roll because it is thin, so it can be easily picked up.

[0010] Furthermore, if the magnetic adhesive sheet portion is divided into two and connected with adhesive tape on the surface opposite to the adhesive surface, when a notice is inserted between the magnetic attachment device and the object to be attached, the notice can be prevented from getting caught on the divided part of the magnetic adhesive sheet portion and getting too far between the magnetic attachment device and the object to be attached.

[Figure 2] 2 is a diagram showing a state in which a notice is posted on an object to be attached using the magnetic attachment device shown in FIG. 1. FIG. [Figure 3] FIG. 10 is a diagram illustrating the configuration of a magnetic attachment device according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0013] (First embodiment) FIG. 1 shows the configuration of a magnetic attachment device 10 according to a first embodiment of the present invention, and FIG. 1(B) shows a cross-sectional configuration taken along line II in FIG. 1(A). FIG. 2 shows a state in which a notice M2 is posted on an attachment target M1 using the magnetic attachment device 10. The magnetic attachment device 10 includes a thin magnetic attachment sheet portion 11 having a magnetic sheet layer 11A. The magnetic attachment device 10 is preferably used to post a notice M2 on a ferromagnetic attachment target M1, such as a whiteboard or metal panel, to which the magnetic sheet layer 11A can be attached.

[0014] The magnetic adhesive sheet portion 11 may be composed of, for example, only the magnet sheet layer 11A, or may have another layer, such as a synthetic resin film layer 11B made of a synthetic resin film, laminated on one side of the magnet sheet layer 11A. The magnet sheet layer 11A is, for example, a sheet made of rubber or resin mixed with magnetic powder such as ferrite, which is then magnetized. The magnet sheet layer 11A may be composed of an isotropic magnet sheet or an anisotropic magnet sheet. The thickness of the magnetic adhesive sheet portion 11 is preferably, for example, 1 mm or less. The shape and size of the magnetic adhesive sheet portion 11 are arbitrary.

[0015] The magnetic attachment device 10 also includes a film portion 12 provided on at least the attachment surface 11C of the magnetic adhesive sheet portion 11 so as to protrude from at least a part of the inner edge to the outer edge. Note that FIG. 1 shows a case where the magnetic adhesive sheet portion 11 is rectangular and the film portion 12 is provided on one side. The film portion 12 is attached to the magnetic adhesive sheet portion 11 with, for example, an adhesive. The attachment surface 11C of the magnetic adhesive sheet portion 11 may be either side when the magnetic adhesive sheet portion 11 is made of only the magnet sheet layer 11A, or it is the side of the magnet sheet layer 11A when the magnetic adhesive sheet portion 11 has layers other than the magnet sheet layer 11A.

[0016] The film portion 12 may be attached only to the attachment surface 11C of the magnetic adhesive sheet portion 11, but is preferably also attached to the surface opposite to the attachment surface 11C. For example, the film portion 12 is preferably provided so as to protrude from the inner edge to the outer edge on the attachment surface 11C, and is also provided so as to protrude from the inner edge to the outer edge at a corresponding position on the opposite surface, and is bonded to each other with an adhesive at the outer edge portion 12A protruding from the magnetic adhesive sheet portion 11. This is because the film portion 12 can be firmly attached to the magnetic adhesive sheet portion 11. When the film portion 12 on the attachment surface 11C side and the film portion 12 on the opposite side are bonded at the outer edge portion 12A, it is preferable to minimize the formation of steps on the film portion 12 on the attachment surface 11C side.

[0017] The width of inner edge portion 12B of film portion 12 attached to magnetic adhesive sheet portion 11 is preferably, for example, 5 mm or more and 2 cm or less. If the width is too narrow, it is difficult to firmly attach film portion 12 to magnetic adhesive sheet portion 11, and if the width is too wide, the adhesive strength of magnetic adhesive sheet 11 may be weakened. The width of outer edge portion 12A of film portion 12 is preferably, for example, 5 mm or more and 2 cm or less. If the width is too narrow, sufficient effect cannot be obtained, and if it is too wide, a large portion of poster M2 is covered.

[0018] Film portion 12 may be provided around the entire periphery, or, for example, may be provided on at least a portion of one side. For example, if magnet sheet layer 11A is made of an isotropic magnet sheet, film portion 12 may be provided anywhere, but if it is made of an anisotropic magnet sheet, it is preferable to provide film portion 12 so that it extends in a direction intersecting the direction of the strongest magnetic force, more preferably in a direction intersecting perpendicularly to the direction of the strongest magnetic force. This is because notice M2 can be firmly held even if it is inserted through film portion 12.

[0019] The film portion 12 is preferably made of, for example, a vinyl chloride resin film, because it has superior durability compared to cellophane tape, vinyl tape, etc. The thickness of the film constituting the film portion 12 is preferably, for example, 0.3 mm or less.

[0020] The magnetic attachment device 10 can be used as follows, for example, when posting a notice M2 such as paper on a ferromagnetic attachment target M1. The notice M2 may be any material that can be sandwiched between the attachment target M1 and the magnetic attachment device 10, and preferred examples include paper and laminated paper. In particular, laminated paper is preferred because it can be easily inserted between the magnetic attachment device 10 and the attachment target M1 and removed from there.

[0021] When posting the notice M2, first, as a preparation step, for example, the magnetic attachment tool 10 is attached to the attachment target M1 by bringing the attachment surface 11C into contact with the attachment target M1. At this time, it is preferable to attach the magnetic attachment tool 10 with the film part 12 facing downward. Next, as a posting step, for example, the notice M2 is held in one hand, and the upper side of the notice M2 is inserted between the magnetic attachment tool 10 and the attachment target M1 from the side of the film part 12, so that the notice M2 is sandwiched between the magnetic attachment tool 10 and the attachment target M1.

[0022] In this case, in this magnetic attachment device 10, the film part 12 is provided so as to protrude from the inner edge to the outer edge of the magnetic adhesive sheet part 11, so that the outer edge part 12A of the film part 12 functions like a shoehorn to assist in the insertion of the notice M2, and the notice M2 can be easily inserted between the attachment target M1 and the film part 12. In addition, since the corners of the attachment surface 11C of the magnetic adhesive sheet part 11 are covered by the film part 12, the notice M2 is prevented from getting caught on the corners of the magnetic adhesive sheet part 11 when inserting the notice M2, and the notice M2 can be easily slid between the attachment target M1 and the magnetic adhesive sheet part 11.

[0023] When removing the notice M2, for example, the notice M2 is held with one hand and pulled in the direction of pulling it out from between the attachment target M1 and the magnetic adhesive sheet part 11. When removing the magnetic attachment device 10 attached to the attachment target M1 or changing the attachment position, for example, the outer edge of the film part 12 is pinched with the hand to remove it.

[0024] As described above, according to this embodiment, the film part 12 is provided on at least the attachment surface 11C of the magnetic adhesive sheet part 11 so as to protrude from at least a part of the inner edge to the outer edge, so that the notice M2 can be easily posted or removed with one hand, and the time and effort of attaching and removing the magnetic attachment device 10 each time the notice M2 is posted or removed can be saved. When replacing the notice M2, the magnetic attachment device 10 remains after the previous notice M2 is pulled out, so the next notice M2 can be inserted and used immediately.

[0025] Furthermore, when removing the magnetic attachment device 10 from the attachment target object M1, it can be easily removed by pinching the outer edge portion 12A of the film part 12 with your hands. Furthermore, during storage, the magnetic attachment device 10 can be stuck on top of each other in a corner, allowing it to be stored in a small space. In addition, even if the magnetic attachment device 10 is dropped, it will not roll around because it is a thin plate, and can be easily picked up.

[0026] (Second embodiment) Fig. 3 shows the configuration of a magnetic attachment device 10 according to a second embodiment of the present invention, and Fig. 3(B) shows the cross-sectional configuration along line II-II in Fig. 3(A). This magnetic attachment device 10 has the same configuration as the first embodiment, except that the magnetic adhesive sheet portion 11 is divided into two in the planar direction, a first magnetic adhesive sheet portion 10A and a second magnetic adhesive sheet portion 10B, and the first magnetic adhesive sheet 10A and the second magnetic adhesive sheet 10B are connected in the planar direction by adhesive tape 13 attached to the surface opposite to the adhesive surface 11C. Therefore, the same components are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0027] With this configuration, in addition to the effects described in the first embodiment, when the notice M2 is inserted between the magnetic attachment device 10 and the attachment target M1, the notice M2 is prevented from getting caught on the divided portion of the magnetic adhesive sheet portion 11 and getting too far between the magnetic attachment device 10 and the attachment target M1.

[0028] Although the present invention has been described above with reference to the embodiments, the present invention is not limited to the above embodiments and can be modified in various ways. For example, although each component has been specifically described in the above embodiments, not all components may be included, and other components may be included. [Explanation of symbols]
