Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stackable display mechanism capable of stacking a plurality of sheet-like magnets or ferromagnetic display bodies and being reversible. Management board, white board, map, etc.
It can be used in offices, schools, lectures, for display and explanation, for interior decoration, and over a large area.

[0002]

2. Description of the Related Art Conventionally, a ferromagnetic material such as an iron plate as an adherend such as a whiteboard is used as an adherend, and a display piece is formed by a sheet-like magnet which is multipolarly magnetized in a stripe shape, and the adherend is formed on the adherend by magnetic force. The display piece of the magnet is not attracted, and the display piece of the magnet is not superimposed on many layers. As an example of stacking the sheet magnets, as shown in FIG. 7, a sheet magnet magnetized in the form of stripes at the same pitch on the adherend 23 and the display piece 24 is used, and different poles are opposed to each other and attracted. There was something to fix. In this case, since the display pitch of the display piece 24 is larger than the thickness of the magnet, a magnetic pole is also generated on the non-magnetized surface side. When the display piece 24 of the magnet is attracted to the adherend 25 made of ferromagnetic material, the leakage magnetic flux density on the non-magnetized surface 26 side increases as shown in FIG. be able to. In this case, the magnetic poles of the two display pieces are oppositely attracted to each other in parallel to each other.

[0003]

When multi-magnetized sheet magnets are stacked as described above, the same poles inevitably repel and the different poles are attracted, so that the striped magnetic poles face each other. Stable adsorption can be obtained only in the state where it is performed. However, when the magnetic poles intersect, only the positions where the different poles oppose each other and repel at the position where the same poles oppose each other. As shown in FIG. 10, the sheet partially floats, so that the repulsive force depends on the crossing angle. Could not be strongly adsorbed. Therefore, the direction of the attraction of the display piece is limited to a fixed value, and the attraction can not be performed in any direction, and the movement of the attraction position is twice as large as the magnetization pitch as shown in FIGS. Each fixed width was limited, and the fixed position could not be freely selected. In addition, when magnets 27 and 28 having different magnetization pitches are stacked, as shown in FIG. 10, repulsion occurs at a position where the same poles are opposed to each other, and there is a disadvantage that the magnets are partially floated and easily fall.

SUMMARY OF THE INVENTION An object of the present invention is to provide a laminated display mechanism capable of preventing an increase in surface leakage magnetic flux density and attaching a display piece to an arbitrary position in a free direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention has been made by focusing on obtaining an efficient magnetic attraction and a magnetic shielding effect by adsorbing a ferromagnetic material such as an iron plate to a magnet and forming a magnetic closed circuit. Things. The laminated display mechanism according to the present invention is obtained by laminating an isotropic or anisotropic multipolar magnetized sheet magnet on one side of a plate-like substrate, and further comprising a ferromagnetic fine powder and an organic polymer binder. Magnetism is shielded by laminating the sheet-like ferromagnetic material, and the magnet is laminated and adsorbed on the entire surface or a part of the surface of the sheet-like ferromagnetic material at a free position regardless of the magnetization pitch and the magnetization direction of the sheet-like magnet. are doing. Further, sheet magnets can be laminated over a plurality of stages while interposing a sheet ferromagnetic material.

The sheet magnet used in the present invention is composed of fine powder of a hard magnetic material such as a ferrite magnet material or a rare earth magnet material and a polymer binder, and has a thickness of 0.1 mm to 3.0 mm.
0 mm is preferable, and the gap between the stripe-shaped multipolar magnetizations is 1.5 mm.
It is preferably about mm to 7.0 mm.

The sheet-like ferromagnetic material is composed of a ferromagnetic fine powder and an organic polymer binder, and the ferromagnetic fine powder may be iron powder (soft iron powder, carbon steel powder, silicon steel powder, reduced iron powder). Powder, atomized iron powder, carbonyl iron powder, etc.) or alloy powder with iron (permalloy powder, sendust powder, alpalm powder, amorphous magnetic alloy powder, etc.) or nickel powder, cobalt powder, carbonyl nickel powder, carbonyl cobalt powder, soft ferrite Powder (manganese / zinc powder, nickel /
Zinc-based powder, triiron tetroxide powder, etc.), and as the organic polymer binder, chlorinated polyethylene, chlorosulfonated polyethylene, ethylene-vinyl acetate copolymer, chloroprene rubber, nitrile rubber, acrylic rubber, etc. Elastomer is used. The particle diameter of the ferromagnetic fine powder is preferably 3 to 300 μm.

[0009] The compounding ratio of the ferromagnetic fine powder to the total amount of the ferromagnetic fine powder and the organic polymer binder is 45 to 70% by volume. The mixing ratio is appropriately determined in consideration of the magnetic susceptibility and the saturation magnetic flux density of the powder. If the content is less than 45% by volume, the performance of the ferromagnetic material used cannot be sufficiently brought out. If the content exceeds 70% by volume, the load applied to the manufacturing machine when forming a sheet increases, and the production becomes difficult. The flexibility of the ferromagnetic material is reduced, and the product lacks practicality. Further, the thickness of the sheet-like ferromagnetic material is appropriately determined by the leakage magnetic flux density of the sheet-like magnet.

In the present invention, a ferromagnetic material such as an iron plate or a non-magnetic material such as wood can be used as the plate-like substrate. When a ferromagnetic material is used for the plate-like substrate, if the magnetized surface of the sheet-like magnet forming the first magnet layer is attracted to the substrate surface, the first magnet layer may be anisotropic single-sided magnetized even if the first magnet layer is anisotropic single-sided magnetized. The leakage magnetic flux on the magnetized surface side becomes strong. However, a magnetically closed circuit can be formed by stacking and adhering the sheet-like ferromagnetic materials, and the leakage magnetic flux can be shielded. Therefore, the sheet-like magnet forming the second magnet layer can be laminated and adsorbed on the surface of the sheet-like ferromagnetic material, and the second magnet layer is affected by the direction of the magnetic poles and the magnetization pitch of the first magnet layer. It can be fixed at any position in any direction without any trouble. Further, a ferromagnetic material is interposed on the surface of the second magnet layer, and the magnet and the ferromagnetic material are alternately laminated.
It is possible to form a magnet layer having more than one step.

When a non-magnetic material is used for the plate-like substrate, the sheet-like magnet constituting the single-sided magnetized first magnet layer fixes the non-magnetized surface to the surface of the plate-like substrate with an adhesive or an adhesive. The sheet-like ferromagnetic material is stacked and adsorbed, the second magnet layer is stacked, and the magnet layer is further stacked and fixed with the ferromagnetic material interposed therebetween, which is the same as the case where the ferromagnetic substrate is used. Yes, similar effects can be obtained.

The first magnet layer and the second magnet layer are not always constituted by one magnet, but are constituted by two magnets in which the first and second magnet layers are attracted to each other. A plurality of magnets can be stacked with a sheet-like ferromagnetic material interposed for each set of magnets. Further, the magnet layer formed by stacking a plurality of stages may be constituted by a stage constituted by one magnet and a stage constituted by two magnets. By interposing the sheet-like ferromagnetic material on the uppermost surface or each stage, it is possible to prevent the surface leakage magnetic flux density from increasing due to the lamination of the sheet-like magnets, and to prevent magnetic disturbance to the magnetic recording medium and the like.

When multi-magnetized sheet magnets are stacked as described above, the same poles inevitably repel and the different poles are attracted, so that the striped magnetic poles face each other. Stable adsorption can be obtained only in the state where it is performed. However, when the magnetic poles cross each other, only the positions where the different poles face each other are attracted, and when the same poles face each other, repulsion occurs. Depending on the crossing angle, the repulsive force cannot be strongly absorbed. Therefore, the direction of the attraction of the display piece is limited to a fixed value, and the attraction can not be performed in any direction, and the movement of the attraction position is twice as large as the magnetization pitch as shown in FIGS. Each fixed width was limited, and the fixed position could not be freely selected. Further, when the magnets 27 and 28 having different magnetization pitches are stacked, as shown in FIG. 10, repulsion occurs at a position where the same poles are opposed to each other, and there is a disadvantage that the magnets are partially floated and easily fall.
