Abstract

PROBLEM TO BE SOLVED: To realize precise parallel movement at every prescribed interval by laminating a sheet-shaped magnet having a surface material with a net- shaped magnetic pole on a base board through a thin magnetic body so as to smoothly move a magnet for display in any direction of the surface of a display board. SOLUTION: The display board consists of a base board 1 consisting of a synthetic resin foamed material, a thin iron sheet laminated on the upper surface of the board 1, and an anisotropic sheet-shaped magnet 3 having a net-shaped magnetic pole. First magnetization and second magnetization are performed and when each strip-shaped magnetic pole is magnetized in the orthogonal direction, all overlapping parts can not changed into the reverse polarity, and the first magnetization is left. Thus, the parts of the same polarity are predominant to realize an eroded condition of the part in which the dissimilar poles overlap, and the net-shaped magnetic pole appears. The sheet-shaped magnet 3 is attracted to the whole surface of the thin iron sheet 2. A decorative film 4 is integratedly attached to the surface side of the sheet-shaped magnet 3, and the peripheral edge of a laminated body is integratedly covered by a frame body 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display plate which uses a sheet-like magnet as a surface material, and a display magnet sheet adsorbed on the surface can be vertically or horizontally slid or moved in parallel at regular intervals. , Not only the panel board type, but also the entire wall surface of a building or a partition used for an exhibition or the like is used as a display board.

[0002]

2. Description of the Related Art Conventionally, as a display plate that can use a magnet, there are a white board and a green board in which an iron plate is covered with a white or green decorative film. In order to use this board made of iron plate as an employee's destination display and action schedule, when a number of display magnet sheets that describe necessary items such as names and destinations are adsorbed in parallel, as shown in FIG. The sticking position is easy to shift and difficult to align. For this reason, it was necessary to write ruled lines on the surface of the board in advance for orderly attachment and to use a guide such as a ruler during alignment work.

As a display plate on which magnet sheets can be aligned without ruled lines or guides, as shown in FIG. 6, a sheet magnet magnetized with multiple poles is used as the surface material of the display plate. There is a device in which a magnet having the same magnetizing pitch as the above is used as a display magnet. When the display magnet sheet is pushed in the longitudinal direction of the strip-shaped magnetic pole (the direction of the arrow in FIG. 6), the S pole of the magnet sheet and the N pole of the surface sheet are attracted to the N pole and S pole of the surface material while being attracted to the rail along the longitudinal direction of the pole. Can be slid on. Further, when the magnet sheet is pushed against the attraction force in a direction orthogonal to the longitudinal direction of the magnetic pole, it repels when it faces the same pole, and it attracts when it faces another pole again. That is,
In this display plate, the attracting position can be adjusted along the magnetic pole for each multiple of the magnetizing pitch, and the magnet sheet can be moved in parallel with accurate dimensions.

[0004]

As described above, the display plate using the multi-pole magnetized sheet-like magnet as the surface material is easier to move and adjust the spacing of the display magnet sheet than the whiteboard type display plate. Is. However, in the case of the display plate shown in FIG. 6, although it can be smoothly moved in the horizontal direction along the strip-shaped magnetic pole without a guide line, the distance t between the two magnet sheets a and b is t.
Is determined by visual inspection and is not automatically determined.

Further, in the direction perpendicular to the longitudinal direction of the strip-shaped magnetic poles, accurate parallel movement can be performed for each multiple of the magnetizing pitch.
The sliding was not as smooth as in the horizontal direction. That is,
In the conventional display plate, the direction in which the display magnet sheet can be slid and the direction in which the display magnet sheet can be moved in parallel at regular intervals is limited to either horizontal or vertical.

When a display plate whose magnetic poles extend in the lateral direction is used, even if the distance t between the two magnet sheets arranged in the horizontal direction is set accurately, the display plate itself is changed by 90 °. Exact positioning of the spacing t could not be automatic unless the magnetic poles were arranged so that the longitudinal direction was vertical. Therefore, the magnet sheet adsorbed on the display plate could not be slid horizontally or vertically, or could be vertically or horizontally moved in parallel or aligned at regular intervals.

In the display panel according to the present invention, the sheet-shaped magnet can be slid on the rail in both the horizontal and vertical directions without resistance, and in the case of the application requiring the precision of the space adjustment. Is to obtain a display plate which can be moved in parallel in both horizontal and vertical directions at regular intervals.

[0008]

In order to solve the above-mentioned problems, the present invention provides one or two magnets as a surface material for forming a net-shaped magnetic pole on the surface, and these magnets are provided through a thin magnetic body. A display plate is formed by laminating a sheet-shaped magnet, a magnetic material and a substrate on a substrate, and provides a display plate having a net-shaped magnetic pole on the surface.

In the case of a single magnet, after the first-order multi-pole magnetization, the second magnet with a magnetic force lower than that of the first magnet is applied in a direction orthogonal to the strip-shaped magnetic pole formed by the first magnetization. Next, magnetizing is performed to form a net-shaped magnetic pole on the surface of the sheet-shaped magnet, and the sheet-shaped magnet is laminated on the substrate via a thin magnetic body, and the sheet-shaped magnet, the magnetic body, and the substrate are integrated. It constitutes the display board.

In the case of two magnets, two sheet-shaped magnets, which are magnetized in multiple poles, are laminated in a direction in which band-shaped magnetic poles are orthogonal to each other to form a net-shaped magnetic pole on the surface. The sheet-like magnet, the magnetic body and the substrate are integrated to form a display plate.

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, one or two magnets are provided as a surface material for forming a net-shaped magnetic pole on the surface, and the magnets are laminated on a substrate through a thin magnetic material to form a sheet-shaped magnet. A display plate is formed by integrating a magnetic material and a substrate, and a display plate having a net-shaped magnetic pole on the surface is provided.

When one sheet-shaped magnet is used as the surface material, the sheet-shaped magnet has a net-shaped magnetic pole formed by two times of primary and secondary multi-pole magnetization. After the first-order multi-pole magnetization, the second-order magnetization is made to have a magnetic force lower than that of the first-order magnetism and a belt-like magnetic pole formed by the first-order magnetization and a second belt-like magnetic pole. Magnetize in the orthogonal direction. That is, the primary and secondary magnetizations are magnetized in a lattice pattern. However, the part where the same pole overlaps remains unchanged N
Although it becomes a pole or an S pole, all the overlapping portions cannot be changed to the opposite polarities by the secondary magnetization, and the polarities of the primary magnetization remain. Therefore, the same-polarity portion becomes dominant, and the portion where the different-polarity overlaps is eroded.
As shown in (A) and (B), a net-shaped magnetic pole can be formed on the surface.

When two sheet-like magnets are used as the surface material, sheet-like magnets in which N and S poles are alternately magnetized in multiple poles are laminated in a direction in which strip-shaped magnetic poles are orthogonal to each other, and a grid is formed on the surface. It is possible to form a magnetic pole having a net shape instead of the shape described above.

On the uppermost surface of the sheet-shaped magnet, a decorative film having a thickness that does not impede the magnetic force may be provided by painting or integrally attaching a decorative film. The magnetizing pitch of the sheet-shaped magnet is easily 2.0 mm and 2.5 mm,
Not limited to this, it may be 1 mm to 10 mm or more. The magnet sheet attracted to the display plate has a magnetizing pitch corresponding to the sheet-like magnet used as the surface material, so that a smooth action can be obtained along the magnetic poles.

The output voltage differs depending on the conditions such as the magnetizing device and the thickness of the magnet, and is not limited to a fixed numerical value. The substrate is not limited to the synthetic resin foam material, but a plate body, plywood,
Cardboard and the like can be used. The magnetic body interposed between the substrate and the sheet-like magnet can be closely adhered when the sheet-like magnets are laminated, and the attracting force can be enhanced by the yoke effect. A thin iron plate or an ultrathin iron foil is often used as the magnetic material, but the same effect can be obtained by using another magnetic material.

Any means may be used as long as the substrate, the magnetic body and the sheet-shaped magnet can be integrated. However, a frame-shaped frame body is attached, arbitrary positions on the laminated side surfaces are adhered, or fixed with a fastener, or Partition frames or supports and wall joints may be used.

The magnetic pole of the display plate according to the present invention is shown in FIG.
As shown in the original size and enlarged view of (B), the N and S poles are arranged in a net shape. As shown in FIG. 3, when the display magnet A having the net-shaped magnetic pole is slid on the display plate having the net-shaped magnetic pole, the multiple of the magnetizing pitch is obtained regardless of whether the display magnet A is slid in the vertical direction or the horizontal direction. Repulsion and adsorption are repeated every time, and it is possible to precisely move in parallel at constant intervals (see arrow Irohani in FIG. 3). At this time, since the width of the magnetic pole is narrow, even if the repulsion action works, the adsorbing action with the adjacent magnetic pole immediately works, so that the sheet does not drop at the time of repulsion, and the sheet moves in parallel at regular intervals like intermittent motion. You can

Further, as shown in FIG. 3, when a magnet B having a multi-pole magnetized in a band shape is used as a display magnet, the magnetic pole can be slid smoothly in the longitudinal direction. Therefore, the display magnet B
It is possible to slide the display plate in either the vertical direction or the horizontal direction simply by changing the direction of 90 degrees. When the multi-pole magnetized display magnet B is attracted to a display plate having a net-shaped magnetic pole,
The narrow portion of the magnetic pole shown in FIG. 4 (B) corresponds to the same pole, but since the magnetic flux density is extremely lower than that of the bulge, it does not feel any repulsive force during operation and slides smoothly. Can move.

[Embodiment 1] FIG. 1 is an exploded perspective view of essential parts showing Embodiment 1 of the present invention. 1 is a substrate made of synthetic resin foam material, 2
Is a thin iron plate laminated on the upper surface of the substrate 1, which keeps the surface uniformly flat and exhibits a yoke effect. An anisotropic sheet magnet 3 has a net-shaped magnetic pole.

A method of forming a net-shaped magnetic pole in this embodiment will be described. First, pitch between poles is 2.5 mm, output voltage is 400
When the primary magnetization is performed at V, strip-shaped N-poles and S-poles are alternately arranged in parallel and multi-pole magnetized. Next, pitch between poles 2.5mm, output voltage 2
Secondary magnetization is performed at 00V. At this time, when the strip-shaped magnetic poles formed by the primary magnetization and the strip-shaped magnetic poles of the secondary magnetization are magnetized in a direction orthogonal to each other, the overlapping portions of the same poles remain unchanged as N poles or S poles, and the different poles overlap. All of the overlapping portions cannot be changed to the opposite polarities by the secondary magnetization, and the magnetic poles of the primary magnetization remain. Therefore, the same-polarity portion becomes dominant, and the portion where the different-polarity overlaps is eroded.
As shown in (A) and (B), net-shaped magnetic poles appear. The sheet-shaped magnet 3 is attracted to the entire surface of the thin iron plate 2.

Numeral 4 is a decorative film integrally attached to the surface side of the sheet-like magnet 3, and may have a thickness that does not impede the attractive force of the sheet-like magnet 3, and in this embodiment, 0.15.
The thing of mm times is stuck. Reference numeral 5 denotes a frame body which covers and integrates the periphery of the substrate 1, the iron plate 2, the sheet-shaped magnet 3 and the decorative film which are laminated.

[0022]

[Embodiment 2] FIG. 2 shows another embodiment, and is an exploded perspective view of a main part. The same substrate 1 and iron plate 2 as in Example 1 are laminated in the same manner. 6 and 7 are sheet-shaped magnets in which N and S poles are magnetized into strips at the same pitch.
Is adsorbed and fixed on the upper surface of the iron plate 2. In FIG. 2, the parallel lines on the surfaces of the sheet-like magnets 6 and 7 show the parallel state of the strip-shaped magnetic poles. The sheet-shaped magnet 7 has a decorative film 4 on the surface.
Are integrally attached, and strip-shaped magnetic poles are arranged and laminated on the upper surface of the sheet-shaped magnet 6 in directions orthogonal to each other. When the sheet-like magnets 6 and 7 which are magnetized in multiple poles are closely adhered and laminated in this manner, a net-like magnetic pole can be formed as in the first embodiment. The periphery of the substrate 1, the iron plate 2, the sheet-shaped magnets 6 and 7 and the decorative film 4 which are laminated is covered with a frame body 5 to be integrated.

In each of the above embodiments, a net-shaped magnetic pole appears on the surface and both have the same function. That is, as shown in FIG. 3, a magnet A having the same net magnetic pole as the surface of the display plate is used as a display magnet, and when the magnet A is pushed vertically or laterally against the attractive force, the adjacent magnetic poles of the same pole are formed. Repulsed,
When it is pushed further, it is attracted to the magnetic pole of the different pole. That is,
Adsorption and repulsion are performed intermittently for each magnetizing pitch, and parallel movement is possible for each multiple of the magnetizing pitch, as indicated by the arrow Irohani in FIG. Therefore, even when a plurality of sheets are aligned vertically and horizontally, the interval adjustment with high dimensional accuracy can be performed, and the sheets can be arranged neatly.

Further, as shown in FIG. 3, as a display magnet, a magnet B magnetized in multiple poles at the same magnetizing pitch as the sheet-shaped magnet for the display plate is attracted and pushed in the longitudinal direction of the magnetic pole of the magnet B. It is possible to slide smoothly on the rail without resistance, and it is possible to slide vertically or horizontally on the display plate only by changing the direction of the display magnet B by 90 °. Display magnet B that is multi-polarized when sliding on the display plate
May correspond to the same pole in the narrow part of the net-shaped magnetic pole on the surface of the display plate, but since the magnetic flux density is extremely lower than that of the bulge, it does not feel any repulsive force during operation and slides smoothly. can do. In the case of the above embodiment, the bulging portion is 140 to 185 gauss and the narrow portion is 3-1.
It was 0 gauss.

In the case of Example 2, if there is a ready-made multi-pole magnetized sheet-shaped magnet, the same net-shaped magnetic pole as in Example 1 can be formed on the surface without using the magnetizing equipment. For example, it is possible to easily construct a display plate having a net-shaped magnetic pole at a necessary place.
