Description

The present invention relates to, for example, a magnet product, and more particularly to a magnet product used by using a wall material made of a material without a magnet, for example, attached to a mirror, a water tank, a wall, a table, a door, or the like.

For example, when suspending or fixing an object to a material such as glass, acrylic, wood, or stainless steel that does not attract magnets, it is common to use suction cup type or adhesive type suspension products or fixing products. It is a target.

The material of the mounting surface is a material with a rough flatness, for example, a wall, table or door made of glass, acrylic, wood, stainless steel, etc., for example, for the purpose of suspending an object or fixing an object. When a suction cup type suspension product is used for the purpose, it is structurally difficult to maintain a sufficient vacuum inside the suction cup, and the hanging object may slip off the wall or the object to be fixed may be from the intended position. There is a problem that it easily shifts.

Sucker-type suspension products and fixing products, which are often used for mirrors, windows, water tanks, tiles, etc., need to generate suction force (suction force) commensurate with the required holding force. Requires a certain amount of vacuum capacity. Therefore, due to the structure of the suction cup, in order to satisfy the weight of the suspension, a certain required thickness and a certain necessary suction cup diameter are required, and there are many design restrictions, resulting in a product lacking in sense. There is.

In addition, when an adhesive type suspension product is used, it is not easy to change the mounting position once the suspension product is fixed to the mounting surface, the degree of freedom for changing the mounting position is lacking, and adhesion is achieved. If the type of suspension product is forcibly removed, there are problems with appearance such as adhesive residue on the mounting surface.

Also, if you look at the mounting products extracted by Internet search, you can see that a wide variety of products are available from various manufacturers. From this, it can be inferred that the user selects various types according to the application, but if it is necessary to purchase various types of products depending on the suspension and the application, it is costly and management aspect. But I have to say that it will be a burden.

The present invention is intended to solve the above-mentioned problems in the prior art, and can be used for other than metal surfaces such as steel plates, and can be easily slipped off, easily displaced, and freely changed in mounting position. A magnet product that is possible and has a structure in which the internal magnet does not rust even when used in a water environment, preferably the suspended part can be easily replaced according to the object, and does not slip off under the load of the suspended object. It is a problem to be provided and solved.

In order to solve such a problem, as the first aspect of the present invention, the entire permanent magnet portion is covered with rubber or resin to deal with rust (corrosion) of the permanent magnet portion, cracking of the permanent magnet portion due to impact, and the like. The configuration is such that the mounting mating material 100 is composed of two or more magnet portions sandwiched from the 100-A surface side and the 100-B surface side.

As a second aspect of the present invention, the magnet portion has a hole through which the shaft portion of the joint portion can be passed for mounting the suspension portion and a recess for accommodating the head portion of the joint portion on the side opposite to the side where the suspension portion is mounted. Further, the permanent magnet portion is covered with rubber or resin. That is, in the second aspect of the present application, for example, the permanent magnet portion having the first surface mounted on the wall surface and the suspension portion coupled to the second surface of the permanent magnet portion facing the first surface are described in the first aspect. Realized as a magnet product characterized by having a through hole provided in the permanent magnet portion for penetrating a joint portion held from the surface side and a covering portion covering substantially the entire surface of the permanent magnet portion. Will be done. At this time, the covering portion preferably completely covers the magnet portion, but may not cover a part of the portion in contact with the shaft portion of the coupling portion in consideration of cost reduction in terms of manufacturing. ..

The recesses that can be stored here are such that the depth h1 and the diameter d1 of the recess have h1 ≧ h2 and d1 ≧ d2 with respect to the thickness h2 and the diameter d2 of the head of the joint portion to be stored. It means a recess in which the head completely fits, but if the head of the joint is in the shape of a so-called countersunk head, it may be in a shape that fits perfectly. It is used in the sense of including both.

Further, the joint portion means a component that realizes that the suspension portion is attached to the magnet portion. A screw-shaped mechanism is generally used as the connecting portion, but it may be any as long as it has a function of connecting the suspension portion to the magnet portion. For example, the connecting portion is made of resin and is also made of resin. Includes those that are connected with a structure that fits with the hook part of. The term "joint" in the present application shall have a broad meaning not limited to the screw-like mechanism.

By using a material such as a resin that transmits the magnetic field lines of the permanent magnet for the covering portion, the magnet portion covered with the covering portion can sufficiently secure, for example, the adsorption strength to be attached to the wall surface. The load applied to the suspension portion is converted into a shearing force acting between the magnet portion and the wall to be attached via the joint portion or the like, and the suction strength makes it sufficiently durable for practical use.

In these cases, it is preferable to use, for example, a neodymium magnet having a strong magnetic force as the permanent magnet built in the magnet portion.

With such an embodiment, the suspension portion and the magnet portion are separated, and the suspension portion having various shapes can be replaced with respect to the magnet portion.

As a third aspect of the present invention, the magnetic flux from the permanent magnet is concentrated in order to obtain a stronger attractive force corresponding to the weak attractive force due to the magnetic force and the slipping off of the applied object. A mode in which a magnetic flux adjusting unit (so-called “yoke”) such as the above is built may be used. That is, the third aspect of the present application further includes a magnetic flux adjusting portion arranged adjacent to the permanent magnet portion in the first aspect and the second aspect, and the covering portion includes the permanent magnet portion and the magnetic flux portion. It is realized as having a configuration for covering the adjusting portion. At this time, the covering portion preferably completely covers the permanent magnet portion and the magnetic flux adjusting portion, but the portion in contact with the shaft portion of the coupling portion is not covered in consideration of cost reduction in terms of manufacturing. You may.

This magnetic flux adjusting unit is typically covered so that the magnetic flux does not leak to directions other than the direction in which the permanent magnet is attracted, but is like a back plate that covers only the side opposite to the attracting direction in a plate shape. Even if there is, it does not matter if the magnetic flux of the permanent magnet itself is sufficient.

As a fourth aspect of the present invention, in the second or third aspect of the present invention, a cushioning portion made of resin, rubber, or the like is provided between the head portion of the joint portion and the covering portion. .. This cushioning part relieves stress due to coupling, etc., and can prevent cracks from entering the covering part of the magnet part, so it is certain that rust will not occur even when strong stress is applied by coupling or suspension. Can be done. For example, even if there is no coating on the joint due to ease of manufacture, by providing a cushioning part on the component, the elasticity of the coating is utilized by the fastening force of the joint, and rust is generated due to the ingress of moisture. Can be prevented.

Although it is possible to provide the permanent magnet portion with a recess that can accommodate the head of the coupling portion, the cost of manufacturing the permanent magnet portion is higher than that of the case where the permanent magnet portion does not have the recess. Therefore, in order to solve this, as a fifth aspect of the present invention, a hole capable of accommodating the head of the coupling portion is provided in the central portion of the permanent magnet portion, and the head of the coupling portion is provided in the central portion of the magnetic flux adjusting portion. A structure having holes through which the shaft portion of the joint portion having a smaller diameter can pass may be used, and the magnet portion may be formed by covering these with a covering portion. That is, in the fifth aspect of the present application, for example, a permanent magnet portion having a first surface to be attached to a wall surface and a suspension portion coupled to a second surface facing the first surface of the permanent magnet portion are formed on the first surface. A first hole having a first diameter and depth sufficient to accommodate the head of the joint to be held from the side, and a second hole having a diameter sufficient to pass the shaft portion of the joint. And, it is realized as a magnet product characterized by including a covering portion that covers the permanent magnet portion and the magnetic flux adjusting portion. With such a structure, the stress at the time of coupling by the head of the coupling portion can be received by the magnetic flux adjusting portion and converted into a shearing force. With such a structure, the magnet portion (permanent magnet portion covered with the covering portion and the magnetic flux adjusting portion) can be easily manufactured, and the cost in terms of manufacturing can be reduced.

Even in the above case, the stress caused by the joint portion causes a problem that the coated portion is cracked and rust is generated. Therefore, as a sixth aspect of the present invention, in the fifth aspect, a cushioning portion made of resin, rubber, or the like may be provided between the head portion of the coupling portion and the covering portion. In such an aspect, the strong stress applied to the covering portion due to coupling or the like can be relaxed, so that the occurrence of cracks can be prevented and the problem of rusting can be prevented.

As a seventh aspect, the cushioning portion is provided with a recess for accommodating the head of the coupling portion and a hole for passing the shaft portion of the coupling portion with a diameter smaller than the head of the coupling portion, and the magnet portion side of the cushioning portion is convex. A large size that has a shaped portion, and the convex portion is housed in a hole or concave portion in the center of the magnet portion in which the permanent magnet portion and the magnetic flux adjusting portion are covered with a covering portion, and the stress of the coupling portion is dispersed and received. It may have a wing portion having a wing area, and the wing portion may be housed in a shallow recess of the coating portion of the permanent magnet portion provided on the side opposite to the suspension portion. That is, in the seventh aspect of the present application, for example, a permanent magnet portion having a first surface to be attached to a wall surface and a suspension portion coupled to a second surface facing the first surface of the permanent magnet portion are formed on the first surface. It has a first hole having a first diameter capable of accommodating the entire joint portion held from the side, and a second hole having a diameter substantially the same as the first diameter, and is substantially coaxially adjacent to the permanent magnet portion. A first hole formed by a magnet portion including a magnetic flux adjusting portion arranged above the permanent magnet portion and a covering portion covering the permanent magnet portion and the magnetic flux adjusting portion, and the first hole and the second hole. A convex portion that fits into the concave portion, a third hole having a third diameter sufficient to pass the shaft portion of the joint portion inside the first convex portion, and a thickness larger than the thickness of the head of the joint portion. A second recess having a depth and an inner diameter larger than the diameter of the head of the joint portion, which extends from the second recess and is arranged so as to expand to the second surface which is a mounting surface of the suspension portion. A cushioning portion comprising a wing portion, wherein the wing portion is completely in a fourth recess having a depth larger than the thickness of the wing portion and a fourth diameter larger than the diameter of the wing portion in the magnet portion. It is realized as a magnet product characterized by being provided with a cushioning portion, which is housed in a magnet. In this case, the buffer portion has a certain area in which the vane portion receives stress and shearing force, but more preferably, it is made of a material such as a resin having a hardness capable of withstanding the stress and shearing force of the joint portion. It is preferable to have.

Further, as an eighth aspect of the present application, in the seventh aspect, a configuration in which the outer edge buffering portion is further arranged on the outer edge of the cushioning portion substantially on the same surface as the surface of the cushioning portion on the side opposite to the suspension portion. Can be taken.

Further, as a ninth aspect of the present application, in the seventh aspect, the covering portion and the cushioning portion in the magnet portion can be integrated by an integrating means including melt bonding.

Further, as a tenth aspect of the present application, there is a suspension portion 3 provided with a hook portion 4 projecting from a position at a certain distance in the vertical direction from the magnet portion in the first mode to the ninth mode. On the mounting surface side facing the side where the hook portion 4 is provided, a suspension portion having a second surface that is substantially in the same plane as the contact surface between the first surface and the mounting surface and that contacts the mounting surface is provided. do.

The second surface includes a surface in which the suspension portion comes into contact with the mounting surface, and is substantially on the same plane as the contact surface between the first surface and the mounting surface. For example, the surface may be separated from the first surface, or may be continuous with the first surface.

Further, in the eleventh aspect, the magnet portion 2 and the suspension portion 3 are movably coupled in the first to tenth modes.

Here, the movable coupling includes, for example, a coupling in which a sleeve is provided when the suspension portion 3 and the magnet portion 2 are connected by a screw, and the suspension portion 3 and the magnet portion 2 can rotate around the screw.

The second to eleventh aspects have been described with respect to the aspect of the mounting mating material 100 including two or more sandwiched from the 100-A surface side and the 100-B surface side, but the mounting material 100 is directly connected with a screw or the like. It may be fixed and used.

For example, it can be used for materials such as glass, acrylic, wood, and stainless steel that do not attract magnets. Since it does not come into contact with each other, even if it is removed after it is attached, the wall where the magnet is attracted will not be damaged. In addition, problems such as slipping off, rusting, and the permanent magnet breaking due to impact can be solved by the magnetic flux adjusting portion, the covering portion, and the cushioning portion. Since it has a replaceable structure, it can be used as a magnet product for fixing or suspension such as holders, racks and hooks of various shapes depending on the application.

It is in a form of being integrally tied by the connecting portion 30.

As a configuration for firmly attaching to the wall that attracts the magnet, the magnet portion 2 accommodates a hole having a diameter / outer material sufficient for the shaft portion 32 of the coupling portion to be inserted, and the head 31 of the coupling portion. Therefore, the recess 13 having a sufficient diameter / depth dimension has a shape engraved on the wall-side surface to which the magnet portion 2 is attached. That is, when the head portion 31 of the joint portion exceeds the swallowing depth of the recess 13 in a state where the magnet portion 2 and the suspension portion 3 are fastened by the joint portion 30, the mounting surface and the magnet portion (not shown) In view of the fact that an unintended gap is generated between the two and the adhesive surface 13B on the mounting surface side, which promotes the separation of the two, the depth of the recess 13 is the head 31 of the joint portion. It is preferable that the amount is sufficient to cover the above. On the other hand, regarding the shape / rigidity of the recess 13 of the magnet portion 2, stress and shearing force by the head 31 of the coupling portion 30 are applied to a certain extent in order to integrally bind the suspension portion 3 to the magnet portion 2 at the coupling portion 30.

Generally, for example, one surface of the magnet portion is magnetically attached to, for example, the mounting surface 100, and the force for peeling the magnet portion from the wall increases as the distance between the shaft related to the magnet portion 2 and the shaft related to the suspended portion increases. Also, the larger the frictional force with the wall (that is, the larger the contact area with the wall), the smaller the value. Therefore, in the ninth aspect of the present application, the magnet product 1 is less likely to be peeled off from the mounting surface 100, for example, as compared with the conventional case.

Further, for example, the force pushing the mounting surface 100 through the second surface is converted into a frictional force generated between the mounting surface 100 and the second surface, and combined with the frictional force on the first surface, the magnet product. It is possible to strengthen the prevention of slipping off.

<10th Embodiment>
A tenth aspect of the present invention is characterized in that, in the ninth aspect, the magnet portion 2 and the suspension portion 3 are movably coupled.

Here, the movable coupling includes, for example, a coupling in which a sleeve is provided when the suspension portion 3 and the magnet portion 2 are coupled with a screw, and the hook portion and the magnet portion can rotate around the screw. As a result, the suspension portion is pulled downward by the load and is easily positioned vertically downward, which is most suitable for obtaining the effect of reducing the force for peeling off the magnet portion 2.

As an eleventh aspect of the present invention, in the ninth or tenth aspect, the magnet portion is further provided with a magnetic flux adjusting portion for concentrating the magnetic flux generated by the permanent magnet portion.

A twelfth aspect of the present invention is characterized in that, in any one of the ninth to eleventh aspects, the magnet portion and the suspension portion are removably coupled by the coupling portion 30. Further, the suspension portion may be composed of two or more portions by the second joint portion 40.

In these embodiments, 3A, 3B, 3C, and 3D in FIG. 10 are given as an example of the suspension portion. Suspension parts are required to have various shapes and functions depending on the application. Therefore, as an example, in addition to the ones shown in FIG. 8, it is desirable to provide those having various shapes and functions in consideration of the use and design, and the examples are not limited to those shown in the drawings.

Further, in these embodiments, the magnet portion is shown to be substantially cylindrical, but the planar shape of the head of the magnet portion related to the found surface is various, such as a polygon such as a triangle, a quadrangle, or a star, or an ellipse. The shape may be good and is not limited to the one shown in the figure.

The magnet product according to the present invention can be used for materials other than metal surfaces such as steel plates, such as glass, acrylic, wood, and stainless steel, which do not attract magnets. Furthermore, it is possible to solve problems such as the permanent magnet being cracked by an impact due to the covering portion. In addition, since it has a replaceable structure, it can be used as a magnet product for fixing or suspending holders, racks, hooks, etc. of various shapes depending on the application. It has a wide range of applications other than metal, and because it has a rust-free structure magnet, it can be used not only in general offices and homes, but also in disaster sites and in water environments outside buildings, such as doors and windows. It can also be used for walls. In addition, since the suspension parts such as holders, racks and hooks of various shapes can be replaced, there is a possibility of wide use in various industries such as general furniture accessories, construction industry, interior industry such as ornaments. ..
