Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 A magnetic substance or a magnet of the same magnetized pitch is originally adsorbed to a board or wall surface that is multipolar magnetized on the front side. However, it may be necessary to use a different magnetized pitch, such as when using a newly purchased magnet on a newly purchased board or purchasing an additional magnet sheet for suction. In this case, the present invention relates to an adsorption mechanism capable of stably adsorbing magnets having different magnetization pitches to each other, and an adsorption substrate used in an adsorption mechanism.

[0002]

[Prior art]

 FIG. 3 is an explanatory view in the case where a magnet multipolarly magnetized at a pitch of 2.5 mm and a magnet multipolarized at a pitch of 3.0 mm are attracted. As shown in FIG. 3, when magnets having different magnetization pitches are attracted to the board surface, only the portions where different poles face each other are attracted, and the portions where the same poles face each other repel. For this reason, it is difficult to fall and be adsorbed, and a portion that rebounds even if adsorbed is in a floating state. That is, when a plurality of sheet-shaped magnets are attracted in parallel, only a part of each sheet is attracted and repelled, and a gap is formed between the sheet surface and the board surface, so that the surface of the attracted sheet-shaped magnet has irregularities.

[0003]

[Problems to be solved by the invention]

 As described above, in the conventional adsorption mechanism, when magnets with different magnetization pitches are attracted to the board surface, the repelled parts rise, so when multiple sheets are attracted in parallel, the surface irregularities become severe and uneven, and the appearance becomes uneven. Bad and sticky sheet magnets often display pictures and characters on the surface side, but these displays are difficult to see. Furthermore, the sheet magnet fixed by suction has high resistance to the force in the direction perpendicular to the sticking surface, but has the property of easily detaching without resistance to the force peeling off a part of the end. For this reason, the conventional suction mechanism has the drawback that if a hand or object hits the part that rebounds and floats, it will easily fall off due to the same action as peeling off the magnet. Attracting and using different magnets was virtually impossible.

[0004] The present invention solves the above-mentioned difficulties, and is intended to be able to attract magnets having different magnetization pitches without lifting off the board surface or wall surface.

[0005]

[Means for Solving the Problems]

 The attraction mechanism according to the present invention solves the above-mentioned problem by interposing an attraction substrate, such as a board surface or a wall surface, on which the magnetic force of multipolar magnetization is exposed on the surface side, and an attraction magnet attracting to these surfaces. Further, by interposing a sheet or a magnetic thin plate provided with an iron powder layer, it is possible to stably fix and fix magnets having different magnetization pitches. As the suction substrate for the suction mechanism, a multipolar-magnetized sheet-like magnet whose magnetized surface is covered with an iron powder layer or a magnetic thin plate is used.

[0006]

[Embodiment of the invention]

 In the case of existing products, the structure of the adsorption substrate such as a board or wall surface where the magnetic force of multipolar magnetization is exposed on the front side is rarely exposed on the surface, and the surface of the multipolar magnetized magnet Many are covered with a synthetic resin film of a thickness that does not hinder the magnetic force, and many have whiteboards and greenboards that are freely erasable or have decorative colors and patterns.

In the present attraction mechanism, when an off-the-shelf adsorbing substrate such as an off-the-shelf board is used, the surface on which the magnetic force of the adsorbing substrate is exposed is covered with a sheet provided with an iron powder layer, so that the adsorbing magnet and the adsorbing magnet can be used. An iron powder layer is interposed between them. When an adsorption magnet with a different magnetization pitch from the adsorption substrate side magnet is adhered from above the iron powder layer, part of the magnetic force is adsorbed to the iron powder layer and another part of the magnetic force penetrates the iron powder layer. Attracts or repels the magnet on the attracting substrate side. At the same time, a part of the magnetic force on the board and the wall side is attracted to the iron powder layer, and the other part penetrates the iron powder layer and attracts or repels magnets having different magnetization pitches.

At this time, the magnet on the suction substrate side such as a board and the magnet for suction attracts to the iron powder layer, so that a part of the magnetic force serving as a repulsive force is absorbed, and at the same time, the magnet is formed on the surface of the iron powder layer. The magnets can be prevented from being lifted up because they are adsorbed. However, when the thickness of the iron powder layer is too thin, the repulsion phenomenon remains strong, and the optimum thickness of the iron powder layer varies depending on the size of the particles and the strength of the magnetic force. If the iron powder layer is too thin, the thickness can be optimized by stacking a plurality of sheets provided with the iron powder layer. A magnetic thin plate can be used instead of the sheet provided with the iron powder layer. The iron powder layer is formed by spraying iron powder on a thin film-like sheet, applying it, and depositing it.

In the present attraction mechanism, the sheet provided with the iron powder layer is not limited to the case where the surface side of the attraction substrate is covered, but the iron powder layer may be interposed by covering the surface of the attraction magnet with the sheet. The attraction magnet is not limited to a sheet shape such as a name tag, but may be a three-dimensional one or may be fixed to the back surface of an inflexible plate.

When a new suction substrate such as a board is newly formed on the assumption that the suction mechanism of the present application is implemented, a sheet provided with an iron powder layer on the front surface of a multi-polar magnetized sheet magnet is integrally formed. May be. In this case, a decorative layer of an arbitrary pattern may be provided on the sheet surface provided with the iron powder layer covering the front surface of the multi-polar magnetized magnet. A similar effect can be obtained by forming a magnetic thin plate in place of the sheet provided with the iron powder layer.

Reference numeral 1 denotes a board surface of an attraction substrate, which is a multi-pole magnetized sheet magnet at a pitch of 2.5 mm. Reference numeral 2 denotes a sheet provided with an iron powder layer, which is attracted and fixed by the magnetic force of the board surface 1, and integrally forms an adsorbed substrate.

The surface of the magnet is covered with a decorative film, and an arbitrary figure or character is displayed.

As shown in FIG. 2, a part of the magnetic force of the board surface 1 is attracted to the iron powder layer of the sheet 2 by the magnetic force lines a. On the other hand, the sheet-like magnet 3 adhered with the sheet 2 interposed also has a part of the magnetic force adsorbed on the iron powder layer of the sheet 2 by lines of magnetic force such as b. The other magnetic force of the board surface 1 and the sheet magnet 3 penetrates the iron powder layer and is attracted or repelled depending on whether the opposite magnetic poles are different or the same. The magnets 3 do not float off the board, and even if a plurality of magnets 3 are attached in parallel, no irregularities are generated on the surface. In the above-described embodiment, the case where the magnets having the magnetized pitches of 2.5 mm and 3.0 mm are attracted has been described. However, the same operation and effect can be obtained with other combinations of the magnetized pitches.

[Effect of the invention]

In addition, a plurality of sheets can be attracted in parallel without unevenness, and are not easily peeled off during or after the attracting operation, so that magnets having different magnetization pitches can be attracted in a stable state.
