Description

[Detailed description of the invention]

[0001]

TECHNICAL FIELD The present invention relates to a suction board that can hang even heavy objects.

[0002]

[Prior Art] Conventionally, the magnetic attraction force has been used to attract objects such as ferrite magnet pieces, which are often used to hold furniture doors and memos, or steel plates used in offices. Rubber magnets, etc. exist.

【0003】

[Problems to be Solved by the Invention] One thing that all things have in common, such as ferrite magnet pieces that have traditionally been used to hold memos, steel plates in offices, and rubber magnets, is the ability to attract Because of its weak adhesion, it can be used for purposes such as adsorbing light memo paper or increasing the closing force of furniture or refrigerator doors, but in cases where a stronger adsorption force is required, such as in an office or the like. If you want to hang notebooks or writing utensils where you want them in your room, or use them to hang soaps and detergents in kitchens or bathtubs, or to hang curtains around entrances, conventional products simply cannot do these things. This had the problem that it did not have enough suction power to suspend or support heavy objects, and could not be used for such heavy objects.

[0004] The present invention has been made in view of the problems of the conventional technology, and its purpose is to use notebooks, writing instruments, etc. in offices and rooms, for example. The purpose is to provide a suction board that can hang and support even fairly heavy objects, such as soap and detergents at bathhouses, hats at entrances, and personal items for going out.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the adsorption board in which a relative magnet is embedded according to the present invention includes a ring-shaped outer ring magnet and a circular space inside the ring-shaped outer ring magnet. A fixed-side adsorption board A has a disk-shaped magnet of opposite polarity fixed to the board, an instrument mounting board B that has the same configuration as the fixed-side adsorption board A, but differs only in polarity, and an instrument mounting board B It is made by fixing the desired appliance C.

[0006] Further, each of the structures described above may be provided with an auxiliary magnet in parallel with the outer ring magnet, and if an iron plate of approximately the same diameter is fixed to the back side of each outer ring magnet, the attraction force is further increased.

[0007]

[Operation] Strong magnetic poles are formed in the outer ring magnet and the disk-shaped magnet inside the outer ring magnet, and these magnets attract each other, so a stronger attraction force is obtained. Further, by providing an auxiliary magnet in parallel with the outer ring magnet, even if the center of gravity of the desired instrument is unstable, it can be prevented from rotating due to the rotational moment of the desired instrument. Furthermore, if the iron plate is attached to the back side, the suction force will further increase.

[0008]

[Example] An example will be described with reference to the drawings. In FIGS. 1 and 2, the outer ring magnet 1 is formed of a permanent magnet material into a ring shape. The disk-shaped magnet 3 is made of a permanent magnet material formed into a disk shape, and has a circular shape with the inner peripheral surface of the hollow part of the outer ring magnet 1.
The outer ring magnet 1 is placed in the center of the outer ring magnet 1 with a gap 2 between the outer ring magnet 1 and the outer ring magnet 1.
The fixed-side suction board A is formed by integrally attaching it to the substrate 4 with the front and back magnetic poles and polarity reversed. The instrument mounting board B is formed of an outer ring magnet 11, a disk-shaped magnet 13, and a substrate 14, which are the same as those of the fixed-side adsorption board A, and the front and back sides of the outer ring magnet 11 and the disk-shaped magnet 13 are Attach only the magnetic poles with opposite polarity.

[0009] The desired device C may be directly attached to the board 14 using, for example, a hook-shaped latch, or the device C may be attached directly to the board 14.
A synthetic resin molded product, such as a detergent container, etc., molded into a desired shape may be entirely attached to the outside of the container 4.

[0010] In FIG. 3, each of the substrates 4 and 14 of the fixed suction board A and the instrument mounting board B
(in the case of Fig. 3, it is shown that it is enlarged in the vertical direction), and each outer ring magnet 1, 11 is
Auxiliary magnets 5 and 1 of opposite polarity are placed in parallel with
5 should be provided.

[0011] In FIG. 4, the iron plate 6 is formed to have the same diameter as the outer ring magnet 1, and is fixed to the end surface of the back side of the outer ring magnet 1.

[0012] Next, experimental results using samples of the present invention will be explained based on A and B of FIG. Ring magnet diameter: 26 mm, thickness: 10 mm Disc magnet: diameter: 20 mm, thickness: 10 mm One side of the above sample was fixed as shown in Figure 5B, and the other side was fixed to a plastic plate (thickness of 3 mm).
mm), as shown in Table 1 below,
Experiments were conducted in the direction (lateral direction, hereinafter referred to as tensile resistance value) and the Y direction (vertical direction, hereinafter referred to as slip resistance value).

[Table 1] ■■■ Turtle shell [0008] ■■■

[0013] As is clear from the values in the table above, the increase ratio of the tensile resistance value between the ring and disc magnets with different polarities and the same polarity is 2480/1500 =
1653 times Increase ratio of slip resistance value / is 1500 / 890 =
1685 times In addition, when a steel plate is added to the back side, the increase ratio of the tensile resistance value / is 2750 / 2480 =
1109 times Increase ratio of slip resistance value / is 1700 / 1500 =
1133 times The above experimental results show that by arranging the ring magnet and disk magnet at different poles, the attractive force can reach 1.6 times.
It was found that an increase of 60% was obtained. It was also found that the suction power could be increased by 10% by adding an iron plate.

[0014]

[Effects of the Invention] Since the present invention is configured as described above, it produces the effects as described below. By implementing the present invention, a strong suction and holding power can be obtained, so for example, it can sufficiently hold notebooks and writing instruments in offices and rooms, soap and detergents in kitchens and bathtubs, hand towel racks, etc., and hat racks around entrances. It can be used for a wide range of purposes, such as personal items for going out, etc. By burying the fixed suction board in several locations of your choice, the equipment mounting board can be easily placed within reach of children, etc. It is very convenient to be able to immediately change the position as needed.
