Description

  The present invention relates to a magnet product, for example, and more particularly to a suspension magnet product that can be used by being attached to a metal wall.

  When the wall is made of metal to which a magnet can be attracted, it is common to use a magnet product. Currently, magnets for suspension such as holders, racks and hooks of various shapes according to the object are on sale. Since magnets are easily rusted, it is necessary to take measures to prevent rust when used in water environments such as kitchens, washrooms, and bathrooms.

  In addition, when it is assumed that a magnet product is manufactured by assembling a suspension device for suspension on a magnet, it may be necessary to suspend various suspension targets. At this time, it is not economical if it is necessary to replace the magnet product every time the weight of the suspended object changes.

  In this regard, for example, in Patent Document 1, the plate-like magnet 4 having N and S poles on the front and back surfaces between the rising portions 2a of the yoke 2 having a U-shaped cross section is the same as the upper end surface of the rising portion 2a of the yoke 2. The hook 3 is attached to the lower end of the yoke 2, the protective sheet 5 is adhered to the outside of the magnet 4 to form the magnetic suspension 1, and the hook 3 is attached to the attachment side. Even if an excessive load is applied to the hook metal fitting 3 by providing a non-slip stopper 6 made of a soft material in which the contact surface 6a to the wall surface protrudes from the upper end surface of the rising portion 2a of the yoke 2 by a certain amount, In addition to the frictional resistance of the protective sheet 5, the pressing force of the anti-slip 6 is applied between the tool 1 and the wall surface, and the frictional resistance with the wall surface is increased accordingly. The technical idea that the wrinkles and drowning of No. 5 are prevented is disclosed. However, in the technical idea of Patent Document 1, it must be pointed out that the magnet is in direct contact with the wall and cannot cope with problems such as damage to the metal wall, slipping, and rusting.

  In Patent Document 2, the magnet 2, the hard cover 3 that covers the magnet 2, the soft cover 4 that fits and holds the hard cover 3, the distal end portion is inserted into the hard cover 3 through the soft cover 4, and the distal end portion 6 is The hard cover 3 includes a hook member 5 that is rotatably supported while being prevented from being pulled out. The hook member 5 has a horizontal flange portion 7 having a front end portion 6, and the horizontal flange portion 7 is extended downward 90. The technical idea of having a vertical hook portion 8 formed by bending more than once and a hook portion 9 formed by extending the lower end of the vertical hook portion 8 and bending upward is disclosed. However, the technical idea of Patent Document 2 has a problem that the attachment portion is limited to a suspended object such as a clothes hanger because of the hook shape.

  As mentioned above, until now, when the wall is made of metal that adsorbs the magnet, magnet (magnet) type mounting products are generally used, because the magnet directly contacts the wall. There were problems such as damaging metal walls, sliding, and rusting.

  Also, looking at the magnet-type mounting products extracted by Internet search, you can see that there are a wide variety of products from various manufacturers. From this, it can be inferred that the user has selected various types of suspension depending on the application, but it would be costly and expensive to purchase various types of products depending on the suspended object and application. It must be said that it will be a burden on the surface.

  Furthermore, Internet information often shows in the user's voice that the adsorption force due to magnetic force is weak, the things that have been hung will slide down, rust comes out and can not be used in water places such as bathrooms, etc. I am dissatisfied.

  The present invention is intended to solve the above-described problems in the prior art, and has a structure in which an internal magnet does not rust even when used in a water environment, and is preferably suspended in accordance with an object. The problem to be solved is to provide a suspension magnet product that can be easily replaced and that does not slide down due to the load of the suspended object.

  In order to solve such a problem, as a first aspect of the present invention, the magnet portion includes a hole through which the shaft portion of the coupling portion can be passed to attach the suspension portion, and a coupling portion on the side opposite to the side where the suspension portion is attached. It has a recess that can accommodate the head, and the permanent magnet portion is covered with elastic rubber or resin such as silicon rubber or elastomer. That is, according to the first aspect of the present application, the first portion includes a permanent magnet portion having a first surface attached to a metal wall surface, and a suspension portion coupled to a second surface facing the first surface of the permanent magnet portion. A suspension magnet product comprising: a through hole provided in the permanent magnet portion for penetrating a coupling portion held from the surface side; and a covering portion covering substantially the entire surface of the permanent magnet portion. As realized. At this time, it is preferable that the covering part completely covers the magnet part. However, in consideration of cost reduction in manufacturing, a part where the shaft part of the coupling part is in contact may not be covered. .

  The recessed portion that can be stored here means that the depth h1 and the diameter d1 of the recessed portion are h1 ≧ h2 and d1 ≧ d2 with respect to the thickness h2 and the diameter d2 of the head portion of the connecting portion to be stored. This means a recess in which the head is completely accommodated. However, when the head of the coupling portion is a so-called countersunk head, the shape may be completely accommodated. It shall be used in the meaning including both.

  Moreover, a coupling | bond part means the components which implement | achieve attaching a suspension part to a magnet part. As the coupling part, a screw-like mechanism is generally used. However, any coupling part having a function of coupling the suspension part to the magnet part may be used. For example, the coupling part is made of resin and is also made of resin. And the like that are coupled with a structure that fits with the hook portion of the. The “joining part” in the present application has a broad meaning that is not limited to a screw-like mechanism.

  Since the covering part such as silicon rubber transmits the magnetic field lines of the permanent magnet, even if the magnet part in this state (permanent magnet covered with the covering part) is used, the adsorption strength to the metal wall that adsorbs the magnet is sufficient Secured. The load applied to the suspension part is converted into a shearing force acting between the magnet part and the wall to be attached via the coupling part or the like, and can sufficiently withstand the practical use due to the adsorption strength.

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

  By setting it as such an aspect, a suspension part and a magnet part are isolate | separated and it becomes an aspect which can be replaced | exchanged for the suspension part of various shapes with respect to this magnet part.

  As a second aspect of the present invention, in order to obtain a stronger adsorbing force corresponding to the above-mentioned voice of dissatisfaction by the user, “the adsorbing force by the magnetic force is weak, and the applied one slips down” It is good also as an aspect which incorporates magnetic flux adjustment parts (what is called a "yoke"), such as iron, which concentrates the magnetic flux from a permanent magnet. That is, the second aspect of the present application is the first aspect, further comprising a magnetic flux adjusting unit disposed adjacent to the permanent magnet part, and the covering part covers the permanent magnet part and the magnetic flux adjusting part. This is realized as having a configuration. At this time, it is preferable that the covering portion completely covers the permanent magnet portion and the magnetic flux adjusting portion, but the portion where the shaft portion of the coupling portion contacts is not covered in consideration of cost reduction in manufacturing. May be.

  Typically, the magnetic flux adjusting section is configured to cover the magnetic flux so that the magnetic flux does not leak in directions other than the direction in which the permanent magnet is attracted. Even if it exists, it does not matter as long as the magnetic force of the permanent magnet itself is sufficient.

  As a third aspect of the present invention, in the first aspect or the second aspect of the present invention, a configuration is adopted in which a buffer portion made of resin or rubber is provided between the head portion of the coupling portion and the covering portion. . This buffer part relieves stress due to bonding and prevents cracks in the magnet cover, ensuring that rusting is prevented even when strong stress is applied due to bonding or suspension. Can be. For example, even if there is no coating of the joint part due to ease of manufacturing, the buffer part is provided on the component parts, and the elasticity of the cover part is utilized by the fastening force of the joint part, so that rust is generated due to moisture entering. 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 manufacturing cost of the permanent magnet portion is higher than when the recess is not provided. Therefore, in order to solve this, as a fourth aspect of the present invention, the center of the permanent magnet portion has a hole that can accommodate the head of the coupling portion, and the center of the magnetic flux adjustment portion has the head of the coupling portion. It is good also as an aspect of the magnet part which set it as the structure which has the hole which the shaft part of a coupling | bond part with a smaller diameter can pass, and coat | covered these with the coating | coated part. In other words, the fourth aspect of the present application is directed to a permanent magnet portion having a first surface attached to a metal wall surface, and a suspension portion coupled to a second surface facing the first surface of the permanent magnet portion. A first hole having a first diameter and a depth sufficient to accommodate a head portion of the coupling portion held from the surface side; and a second hole having a diameter sufficient to pass the shaft portion of the coupling portion. This is realized as a suspension magnet product comprising a hole and a covering portion that covers the permanent magnet portion and the magnetic flux adjusting portion. With such a structure, it is possible to receive the stress at the time of coupling by the head portion of the coupling unit by the magnetic flux adjusting unit and convert it into a shearing force. By adopting such a structure, the magnet part (the permanent magnet part and the magnetic flux adjusting part covered with the covering part) can be easily manufactured, and the manufacturing cost can be reduced.

  Even in the above case, there is a problem that rust is generated due to cracks in the covering portion due to the stress of the joint portion. Therefore, as a fifth aspect of the present invention, in the fourth aspect, a buffer portion made of resin or rubber may be provided between the head portion of the coupling portion and the covering portion. According to such an embodiment, since a strong stress applied to the covering portion due to bonding or the like can be relieved, the occurrence of cracks can be prevented and the problem of the occurrence of rust can be prevented.

  As a sixth aspect, the buffer portion is provided with a recess for accommodating the head portion of the coupling portion and a hole through which the shaft portion of the coupling portion is passed with a smaller diameter than the head portion of the coupling portion, and the magnet portion side of the buffer portion is convex. The convex portion is accommodated in a hole or a concave portion in the central portion of the magnet portion in which the permanent magnet portion and the magnetic flux adjusting portion are covered with the covering portion, and the stress at the coupling portion is dispersed and received. It is good also as an aspect which has a wing | blade part which has this area, and this wing | blade part is accommodated in the shallow recessed part of the film part of the permanent magnet part provided in the opposite side to the said suspension part. That is, according to a sixth aspect of the present application, a permanent magnet portion having a first surface attached to a metal wall surface and a suspension portion coupled to a second surface facing the first surface of the permanent magnet portion are provided in the first aspect. A first hole having a first diameter capable of accommodating the entire coupling portion held from the surface side, and a second hole having substantially the same diameter as the first diameter, and adjacent to the permanent magnet portion substantially coaxially Formed by a magnetic part including a magnetic flux adjusting part, a permanent magnet part and a covering part covering the magnetic flux adjusting part, 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 coupling portion into the first convex portion, and a thickness of the head portion of the coupling portion A second recess having a large depth and an inner diameter greater than the diameter of the head of the coupling portion, and extending from the second recess, A cushioning portion provided with a wing portion that is arranged so as to expand on the second surface, which is a brazing surface, and the magnet portion has a depth greater than the thickness of the wing portion and a diameter of the wing portion. The suspension magnet product is characterized by including a buffer portion in which the wing portion is completely accommodated in a fourth concave portion having a large fourth diameter. In this case, the buffer portion has a certain area to receive the stress and shear force, but is more preferably a material such as a resin having a hardness capable of withstanding the stress and shear force by the joint portion. Preferably there is.

  Further, as a seventh aspect of the present application, in the sixth aspect, the outer edge buffering portion is further arranged on the outer edge of the buffering portion on a surface substantially opposite to the surface of the buffering portion opposite to the suspension portion. Can take.

  Furthermore, as an eighth aspect of the present application, in the sixth aspect, the covering portion and the buffer portion in the magnet portion can be integrated by an integrating means including fusion bonding.

  When the wall to be attached is made of a metal that adsorbs the magnet, the permanent magnet part or the like is not in direct contact with the covering portion, so that even if it is removed after being attached, the metal wall to which the magnet is adsorbed is not damaged. In addition, problems such as sliding down and rusting can be solved by the magnetic flux adjusting section, the covering section, and the buffer section. Since it has a replaceable structure, it can be used as a magnet product for suspension such as holders, racks and hooks of various shapes according to the application.

The magnet portion 2 and the suspension portion 3 that are formed by being covered with each other are integrally fastened by the coupling portion 30.

  As a structure for firmly attaching to the wall that attracts the magnet, the magnet portion 2 accommodates a hole having a diameter / outer material sufficient to allow the shaft portion 32 of the coupling portion to be inserted, and the head portion 31 of the coupling portion. Therefore, the recess 13 having a sufficient diameter / depth dimension is provided with a shape carved on the wall side surface of the magnet unit 2. That is, when the head portion 31 of the coupling portion exceeds the recess depth of the recess 13 in a state where the magnet portion 2 and the suspension portion 3 are fastened by the coupling portion 30 (not shown), the metal wall surface and the magnet portion. In view of the fact that an unintended gap is formed between the metal wall surface 2 and the bonding surface 13B on the metal wall surface 2 side, and the peeling of the both is promoted, the depth of the concave portion 13 is the head 31 of the coupling portion. It is preferable that the thickness be sufficiently covered. On the other hand, with respect to the shape / rigidity of the concave portion 13 of the magnet portion 2, a certain amount of stress and shearing force are applied by the head portion 31 of the coupling portion 30 so that the suspension portion 3 is integrally fastened to the magnet portion 2 by the coupling portion 30. However, the magnet portion 2 is sufficiently received.
