Owing to the netted magnetic poles, the adsorbed magnet can shift along the magnetic poles on the surface of the substrate smoothly and in certain interval in both longitudinal and transverse directions.

Description

Display plate

The present invention relates to that its surfacing uses sheet magnet, the expression that is adsorbed in this surface can be slided or parallel at regular intervals mobile display plate along its vertical, horizontal with magnetic sheet, this display plate singly is not limited to as the board-like display plate of presentation surface, can be as the display plate of used Region Segmentation such as the metope of buildings, exhibition etc. yet.

Always, as the display plate that uses magnet, having a kind of is to cover " blank " or " green plate " that white or green decorating film constitutes on iron plate.In order to express company clerk's whereabouts or predetermined activity on the display plate that constitutes on this iron plate, will with the expression of putting down in writing necessary items such as name whereabouts with the magnetic sheet multi-disc arranged side by side absorption on it, but this moment as shown in Figure 5, inhales the subsides easy changing of the relative positions in position between magnetic sheet mutually and be difficult for coming into line.Therefore,, must draw the grid lines in advance, perhaps when arranging, use instruments such as chi on the display plate surface for absorption fitly.

Just the display plate of magnetic sheet proper alignment can be had as shown in Figure 6 a kind of as instruments such as not needing grid lines and chi, the surfacing of its display plate uses multipole magnetized sheet magnet, and will the magnet of identical magnetization spacing be arranged as representing to use magnetic sheet with the sheet magnet with surfacing.If along the length direction (Fig. 6 direction of arrow) of banded magnetic pole pushing expression magnetic sheet, under then extremely opposed with the N utmost point S of surfacing and the state that adsorbing mutually at the S of the magnetic sheet utmost point N utmost point, can be along the length direction of magnetic pole as slippage like the slip in orbit.In addition,, repel mutually when then opposed, attract mutually when opposed with heteropole once more with homopolarity when magnetic sheet being overcome suction to the time with the direction pushing of the length direction quadrature of magnetic pole.That is, this display plate can be adjusted absorption position along magnetic pole with the multiple of magnetization spacing, with the parallel mobile magnetic sheet of correct size.

As mentioned above, use surfacing to be compared with " blank formula " display plate by the display plate of multipole magnetized sheet magnet, expression is moved and is adjusted at interval and carry out easily with magnetic sheet.But display plate shown in Figure 6 can move in horizontal direction shown in Figure 6 along banded magnetic pole smoothly though just need not rule, and the interval t between two magnetic sheet a and the b will wait with range estimation and judge, can not determine automatically.

In addition, with the direction of the length direction quadrature of banded magnetic pole, though can not as above-mentioned horizontal direction, move smoothly to move with the multiple of magnetization spacing is correctly parallel.That is, traditional display plate can make direction that expression slides with magnetic sheet and at regular intervals can parallel mobile direction be limited to level or vertical among some directions.

When the display plate of the length direction horizontal expansion of using magnetic pole, if will correctly set the interval t of along continuous straight runs two magnetic sheets arranged side by side, only otherwise display plate self is rotated 90 ° of angles, it is configured to the magnetic pole length direction is vertical direction, and the correct location of t just can not be finished automatically at interval.Therefore, the magnetic sheet that is adsorbed on the display plate just can not horizontal, longitudinal sliding motion, also be not easy with its at regular intervals parallel the moving of size vertical, horizontal come into line.

The object of the present invention is to provide following a kind of display plate, no matter this display plate is that horizontal direction or vertical direction can both make the sheet magnet slide as sliding non-resistance ground in orbit, when being used in when requiring purposes that high precision adjusts at interval, no matter be level or vertical direction, can both parallelly at regular intervals move.

In order to solve above-mentioned problem, display plate provided by the invention, be provided with 1 or 2 magnets on the surface as the surfacing that forms netted magnetic pole, this magnet is layered on the substrate by thin magnetic, sheet magnet and magnetic and substrate junction integrator constitute display plate, are formed with netted magnetic pole on the surface of display plate.

Under the situation of a slice magnet, carry out the 1st time multipole magnetized after, direction at the banded magnetic pole quadrature that forms with the 1st magnetization, to carry out the 2nd magnetization than the 1st the weak magnetic force of magnetization, thereby form netted magnetic pole in the sheet magnet surface, this sheet magnet is layered on the substrate by thin magnetic, and makes sheet magnet, magnetic and substrate junction integrator, constitute display plate.

Under the situation of two magnets, two multipole magnetized sheet magnets are stacked by the mutually orthogonal direction of banded magnetic pole, form netted magnetic pole on the surface, by magnetic it is layered on the substrate, and sheet magnet, magnetic and substrate are become one, constitute display plate.

The present invention is provided with a slice or two magnets as the surfacing that forms netted magnetic pole on the surface, this magnet is layered on the substrate by thin magnetic, and sheet magnet, magnetic and substrate are become one, thus constitute display plate, be provided at the display plate that there is netted magnetic pole on the surface.

When the sheet magnet that uses as surfacing during as a slice, this sheet magnet multipole magnetizedly forms netted magnetic pole such twice by the 1st time and the 2nd time.The 1st time multipole magnetized after, carrying out the 2nd magnetization, and magnetize in the banded magnetic pole that the 2nd magnetization formed and the direction of the banded magnetic pole quadrature of the 1st magnetization formation than the 1st the weak magnetic force of magnetization.That is,, be magnetized into clathrate by the 1st time and the 2nd magnetization.So the overlapping part of same pole does not change, remain the N utmost point or the S utmost point, and the overlapping part of heteropole is through 2 magnetization, lap can not all change over opposite polarity, also can leave magnetized polarity the 1st time.Therefore, homopolarity partly takes advantage, and is the state that corrodes the heteropole lap, as Fig. 4 (A) (B) shown in, can form netted magnetic pole on the surface.

When using two sheet magnets as surfacing, with N, the S utmost point alternately multipole magnetized the sheet magnet stacked by the mutually orthogonal direction of banded magnetic pole, just can surface formation be not clathrate but with above-mentioned the same netted magnetic pole.

The top of sheet magnet also has by coating or paste to go up cosmetic sheet and wait the decorating film that thickness does not hinder magnetic force is set.The magnetization spacing of sheet magnet is easier to use with 2.0mm or 2.5mm ratio, but is not limited to this, can be 1mm-10mm, and is good greatly again.Be adsorbed in expression on the display plate and use to have with magnetic sheet and magnetize the magnetic sheet of spacing accordingly, therefore can move smoothly along magnetic pole with the used sheet magnet of surfacing.

In addition, output voltage is not limited to certain numerical value with conditions such as magnetizing assembly and magnet thicknesses and different.Substrate is not limited to the foamed material of synthetic resin, for example can use plate body, scale board, cardboard etc.The magnetic that is clipped between substrate and the sheet magnet can fit tightly when stacked sheet magnet, and because yoke effect can improve absorption affinity.Use sheet iron and iron foil as thin as a wafer mostly as magnetic, but use other magnetics also can obtain identical effect.

As long as substrate, magnetic and sheet magnet are become one, whatsoever method is all right.Picture frame shape framework for example can be installed, can be bonding or with the optional position of fixture fixed bed poststack side, also can utilize the joint filler etc. of frame, support and the metope of separation.

The magnetic pole of display plate of the present invention is shown in the full scale drawing and enlarged drawing of Fig. 4 (A) in (B), and N, the S utmost point are configured to netted.As shown in Figure 3, when when the expression with netted magnetic pole has the display plate of netted magnetic pole with magnet A on, sliding, no matter in which vertical or horizontal direction, can both repel repeatedly and adsorb with the multiple of magnetization spacing, it is parallel mobile (to see arrow a, b, c, d among Fig. 3) critically at certain intervals.At this moment, because magnet pole widths is very narrow,,, can do parallel moving at certain intervals as doing geneva motion so magnetic sheet can not fall yet when repelling so, also work at once with the attraction of adjacent pole even repulsive interaction is arranged.

In addition,, use banded multipole magnetized magnet B to use magnet, then can slide smoothly along the length direction of magnetic pole as expression if as shown in Figure 3.Therefore, if make expression with magnet B towards changing 90 °, just can be along the vertical or horizontal either direction slip of display plate.When being adsorbed in multipole magnetized expression on the display plate with netted magnetic pole with magnet B, venturi portion at the magnetic pole shown in Fig. 4 (B) is that homopolarity is relative, but because specific permeability is extremely low mutually with heaving part, so complete imperceptible repulsive force during action can slide smoothly.

Fig. 1 is the major part exploded perspective view of the embodiment of the invention.1 is the substrate that is made of synthetic resin foam, and 2 for being layered in the sheet iron above the substrate 1, makes the surface keep uniform flatness, and can bring into play yoke effect.3 is anisotropic sheet magnet, has netted magnetic pole.

Explanation in the present embodiment forms the method for netted magnetic pole.At first carry out the 1st magnetization, so by multipole magnetized, the banded N utmost point, the S utmost point are alternately side by side with interpolar spacing 2.5mm, output voltage 400V.Then, carry out the 2nd magnetization with interpolar spacing 2.5mm, output voltage 200V.At this moment, if making the banded magnetic pole of the 1st magnetization formation and the banded pole orientation of the 2nd magnetization formation magnetizes orthogonal theretoly, then remain unchanged at the overlapping segment polarity of same pole, still be the N utmost point or the S utmost point, and in the overlapping part of heteropole, the 2nd magnetization can not make lap all change over opposite polarity, can residual the 1st magnetized magnetic pole.Therefore, the part of homopolarity is preponderated, and is the state that corrodes the heteropole lap, shows as the netted magnetic pole shown in Fig. 4 (A), (B).This sheet magnet 3 is attracted on whole of sheet iron 2.

4 for sticking on magnet 3 lip-deep cosmetic sheet with being integral, and its thickness only otherwise can hinder the absorption affinity of sheet magnet 3 to get final product in the present embodiment, is being pasted the cosmetic sheet of 0.15mm.5 is framework, and the periphery with substrate 1, iron plate 2, sheet magnet 3 and cosmetic sheet after stacked envelopes and becomes one.

Fig. 2 shows other embodiment, is the exploded perspective view of major part.Substrate 1 and iron plate 2 are identical with embodiment's 1, carry out stacked equally.6, the 7th, with the extremely multipole magnetized sheet magnet that becomes band of N, S, the upper side of iron plate 2 is fixed in 6 absorption of sheet magnet with uniform distances.In Fig. 2, the parallel lines on sheet magnet 6 and sheet magnet 7 surfaces illustrate the state arranged side by side of banded magnetic pole.The surface of sheet magnet 7 is pasted with cosmetic sheet 4 with being integral, and with the mutually orthogonal direction configuration layer of banded magnetic pole be stacked in sheet magnet 6 above.So multipole magnetized sheet magnet 6 and 7 is fitted tightly stackedly, can form netted magnetic pole similarly to Example 1.Periphery after stacked coats and becomes one with substrate 1, iron plate 2, sheet magnet 6,7 and cosmetic sheet 4 with framework 5.

The foregoing description all presents netted magnetic pole on the surface, all have identical effect.That is, as shown in Figure 3, use magnet, use magnet A, magnet A is passed to vertical or transverse direction, can repel each other with adjacent homopolarity magnetic pole, but further passing is then inhaled mutually with opposite pole if overcome absorption affinity with netted magnetic pole identical with the display plate surface as expression.That is, intermittently attract and repels, shown in the arrow abcd of Fig. 3, can do parallel mobile by the multiple of magnetization spacing in each magnetization spacing.Therefore, when multi-disc being represented arrange, also can carry out interval adjustment longitudinal and transversely, it is neatly and cleanly arranged with very high dimensional accuracy with magnetic sheet.

In addition as shown in Figure 3, magnet B after the magnetization spacing identical with the sheet magnet used with display plate of absorption on the display plate is multipole magnetized is as representing to use magnet, if magnet B is pushed to its magnetic pole length direction, just can be as the level and smooth slippage in non-resistance ground like the slip in orbit, as long as will represent with magnet B towards changing 90 °, just can be along the vertical or horizontal either direction slip of display plate.When on display plate, sliding, multipole magnetized expression can occur the relative situation of homopolarity with magnet B at the venturi portion of the netted magnetic pole on display plate surface, but because specific permeability is extremely low mutually with heaving part, thus in action complete imperceptible repulsive force, can slide smoothly.Again, in the above-described embodiments, heave part and be 140-185 Gauss, venturi portion is 3-10 Gauss.

Under the situation of embodiment 2, if ready-made multipole magnetized sheet magnet arranged, then just can form the netted pole surface identical with embodiment 1 without magnetizing equipment, wait essential place at the construction field (site), can make display plate easily with netted magnetic pole.

Because the present invention has aforesaid formation and effect, so, if according to purposes use respectively multipole magnetized expression with magnet with have a netted magnetic pole represent to use magnet, then expression uses magnet in the level on display plate surface, vertical smoothly slippage of either direction, or critically does the parallel of certain intervals and move.Therefore, expression is come into line with magnet, can make accurately neat expression as having guide rail or leading line in longitudinal and transverse either direction.
