Description

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

  In offices and homes, various hooks are used to hang walls, clothes, and accessories on the wall. In this case, if the wall is wooden, for example, a hook with a screw is used. However, if the wall is made of metal that can be attracted by a magnet, it is common to use a hooked magnet (magnet) product. When searching on the internet, many manufacturers sell hooked magnet products. I know that.

JP 2008-43561 A JP 2007-167429 A

  In Patent Document 1, a magnet board magnetically attached to a magnetic wall, a wire case part positioned on the same axis and a screw part screwed to the magnet board, and a central part orthogonal to the axis of the wire case part, A recessed hole with a seat formed on the bottom is recessed, a through hole with a smaller diameter than the fixed hole is provided from the seat of the fixed hole, and a guide groove communicating with the fixed hole and the through hole is formed from the end surface of the wire case. Although the technical idea about the magnet hook which consists of a wire case and a hanger part which makes the sphere fixed to the upper end of the wire which attaches a hanger sit in the seat part of a stop hole, and a wire is located in a penetration hole or a guide groove is disclosed Since this is an invention in which a wire portion is interposed between the magnet portion and the hook portion, it must be pointed out that the structure is not suitable for anything other than a special purpose such as hanging a work of art.

  In Patent Document 2, two rubber magnets are joined, the upper end of the rubber magnet is connected, a hook portion is installed in front of the front rubber magnet, and an adhesive surface for attaching a release sheet to the back of the rear rubber magnet is provided. Although the technical idea to be provided is disclosed, it must be pointed out that since the two rubber magnets are fixed to each other only by a magnetic force, the invention cannot expect a sufficient suspension load.

  When the wall is made of metal that adsorbs the magnet, a magnet type magnet is generally used. However, the magnet is in direct contact with the wall, so the metal wall is damaged, slips, and rusts. There was a problem such as coming out.

  If you look at the magnetic hooks that are extracted by Internet search, you can see that there are many different products from various manufacturers. From this, it can be inferred that the user chooses hooks of various shapes depending on the application, but it is expensive to manage various types of magnetic hooks depending on the application. But I have to say it will be a burden.

  In addition, what is often seen in the user's voice in Internet information is the complaint that the attracting force due to the magnetic force is weak and the one that has been dropped falls.

  The present invention is intended to solve the above-mentioned problems in the prior art, and provides a hook magnet product and a hooked magnet product that can replace the hook portion and have a sufficient load applied to the hook. Is a problem to be solved.

  In order to solve such a problem, as a first aspect of the present invention, as a first aspect of the present invention, the permanent magnet portion has a hole through which the shaft portion of the coupling portion for attaching the hook portion can be passed and the coupling portion on the side opposite to the side where the hook portion is attached. In this embodiment, the permanent magnet portion is covered with silicon rubber or the like.

  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 component which implement | achieves attaching a hook part to a magnet part (coupling | bonding). As the coupling part, a screw-like mechanism is generally used. However, the coupling part only needs to have a function of coupling the hook part to the magnet part. For example, the coupling part is made of resin and is also made of resin. The “coupling portion” in the present application has a broad meaning that is not limited to a screw-like mechanism, such as those that are coupled with a structure that fits to the hook portion.

  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 hook portion is converted into a shearing force acting between the magnet portion and the wall to be attached via the coupling portion or the like, and can sufficiently withstand the practical use due to the adsorption strength. In addition, it is preferable that the covering portion completely covers the magnet portion, but when the portion where the shaft portion of the coupling portion is in contact is not covered or the magnet portion and the hook portion are integrated by the coupling portion. A mode in which a silicon rubber cover is covered afterward so as to substantially cover only the magnet portion may be employed.

  In these cases, it is preferable to employ a neodymium magnet as the permanent magnet built in the magnet portion.

  By adopting such an aspect, the hook part and the magnet part are separated from each other, and an aspect in which hook parts having various shapes can be attached to the magnet part, that is, an aspect in which the hook part can be replaced is obtained. .

  As a second aspect of the present invention, in order to respond to the above-mentioned user's dissatisfaction voice, an aspect in which a magnetic flux adjusting section (so-called “yoke”) made of iron or the like that concentrates the magnetic flux from the permanent magnet in the magnet section is built-in, It is also good.

  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 described above, when the hook portion and the magnet portion are coupled, for example, when the covering portion completely covers the magnet portion, if the tightening strength by the screw-shaped coupling portion or the coupling force by fitting is too large Prior to the present invention, there was a problem that a crack was generated in the magnet rubber covered with silicon rubber or the like, and moisture or the like entered from the crack to generate rust inside.

  Therefore, as a third aspect of the present invention, in the first aspect or the second aspect of the present invention, a configuration in which a buffer portion made of resin or rubber is provided between the head portion of the coupling portion and the covering portion. Take. This buffer part relieves stress due to bonding and prevents cracks in the magnet rubber part such as silicon rubber. Therefore, even when strong stress is applied by bonding or suspension, rust is generated. It can be surely prevented.

  As described above, it is possible to provide the permanent magnet portion with a recess that can accommodate the head of the coupling portion, but the cost of manufacturing 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 which set it as the structure which has the hole which can pass the axial part of a coupling | bond part with a smaller diameter, and coat | covered these with the coating | coated part. 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 of the present invention for reducing the manufacturing cost and preventing the cover from cracking due to stress caused by the joint, etc., a recess for housing the head of the joint in the buffer and the head of the joint A hole having a smaller diameter and through which the shaft portion of the coupling portion passes is provided. Further, the magnet portion side of the buffer portion has a convex portion, and the convex portion covers the permanent magnet portion and the magnetic flux adjusting portion with a covering portion. It has a wing part that is housed in a hole or concave part in the center of the magnet part and has an area large enough to disperse and receive the stress of the coupling part, and the wing part is opposite to the hook part of the magnet part It is good also as an aspect accommodated in the shallow recessed part provided in the side. 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.

  As a product, it is good also considering only the magnet part which coat | covered the permanent magnet part except the buffer part in 6th aspect, and the magnetic flux adjustment part with the coating | coated part as a magnet product for hooks. In this case, it is possible to use the buffer portion as an independent part by applying various colors and changing the combination. Only the magnet part as in this case is the tenth aspect.

  As described above, the mode in which the buffer part is separated from the magnet part has a merit that the user can realize various combinations, but also has a demerit of losing the buffer part. In order to solve this, as a seventh aspect of the present invention, the buffer portion and the covering portion may be integrated by melting or the like, and this may be used as a hook magnet product.

  The magnet part of the hook magnet product only needs to have sufficient adsorption power to the wall, but when various things are hung on the wall etc., there are cases where various designs such as coloring are required as products. is there. Therefore, as an eighth aspect of the present invention, in the first to seventh aspects of the present invention, coloring or the like is performed on the side where the hook portion of the magnet portion is attached, the opposite side of the magnet portion (side attracting to the wall), or the like. It is good also as an aspect with the decoration part which can do. As a result, it is possible to have a linkage with the design of the shape or the like of the hook portion, and it is possible to improve the attractiveness as a product. In addition, although a decoration part may be comprised so that it can be fitted and removed from a magnet part, it is good also as an aspect integrated by the coating | coated part and fusion | melting.

  Thus, in the magnet product (magnet hook) in which the magnet portion and the hook portion are separated from each other, the hook portion can be exchanged depending on the application, and thus it can be said that the main element is the magnet portion. However, the magnet hook does not function unless it has a hook, and it goes without saying that the hook is an essential element. Therefore, as a ninth aspect of the present invention, in the first to eighth aspects of the present invention, the hook portion is integrated with the magnet portion by the coupling portion. This makes it possible for buyers of magnet hooks to purchase magnet hooks with hooks, so they can be used as soon as they are purchased without having to procure the hooks themselves. If you want to use, it is convenient to replace only the hook part.

  Up to this point, the magnet part has been described on the assumption that it is used alone, but a plurality of magnet parts may be used in a horizontal connection. In that case, since the suspension is supported by a plurality of magnet portions, the weight of the suspension can be increased. In such a case, it is preferable to provide a product in which a plurality of magnet sections are arranged side by side and connected together at various distances.

  The shape of the magnet viewed from above is a circle and a cylindrical shape is generally used in three dimensions. However, the shape viewed from above may be a triangle, a quadrangle, or a polygon such as a star. I do not care. Rather, it can be said that the various shapes of products may be preferred in terms of design, although it costs more in manufacturing.

  When the wall to be attached is made of metal that adsorbs the magnet, permanent magnets do not come into direct contact with the cover, so even if the magnet hook is removed after attachment, the metal wall to which the magnet is adsorbed will not be damaged. . Further, problems such as slipping of the magnet part and rusting can be solved by the magnetic flux adjusting part, the covering part and the buffer part. Furthermore, since the hook part has a replaceable structure, it can be used as a magnet hook having hook parts of various shapes depending on the application.
