開示に関わるものである。Detailed Description of the Invention (Industrial Application Field) This invention relates to the protection of a magnet in an engagement tool that utilizes the magnetic force of a permanent magnet, and in particular to the protection of a magnet by coating the surface of the magnet with metal using an electroplating method. Disclosure of an extremely novel engaging tool that aims to create surface strength of a magnet as a fitting, create adhesion or impact resistance of a magnet, or create surface gloss and generate a magnetic gap. It is related.
（従来技術）
而して、従来この種の係合具に於いては概ね使

けている点を相補うようにしたものである。(Prior art) Conventionally, in this type of engagement tool, the permanent magnet used is generally covered with a thin brass plate or the like, and the magnet,
In particular, ferrite magnets and the like are weak in impact, abrasion, and abrasion due to their structural fragility, and are designed to compensate for the lack of aesthetic appearance on the surface.

嵌め合い間隙を有することよりして必然的に係合

品等に対する使用性を著しく損じたものである。(Problems to be Solved by the Invention) However, such a method requires processing of the brass plate to be coated, particularly press punching, drawing or plating, as well as mounting and caulking. This requires a lot of time and effort to manufacture, install, and assemble, and at the same time, it causes an increase in the cost of the product due to problems with the materials used.
In addition, the weight of the engaging tool is inevitably heavy due to the material used, and the fitting gap between the inner magnet and the outer material inevitably increases the bulk of the engaging tool. The size is too large, and its usability for high-end accessories and the like is significantly impaired.
更に又、この嵌め合い間隙の介在をもつて、先

キ音を発生する等の問題点があつた。 Furthermore, due to the interposition of this fitting gap, if the previous crimping was not done reliably, or if the fitting was used over time, the internal permanent magnet may swing due to loosening of the fitting part. There were problems such as a significant reduction in magnetic force as an engaging tool or generation of rattling noise during use.
そこでこれ等の問題点を一掃するために原出願
に係る発明を提案したが原出願では金属皮膜を構
成する際に磁気通路となり磁場を構成する金属皮
膜素材で覆うようにしていた。 Therefore, in order to eliminate these problems, the invention related to the original application was proposed, but in the original application, when forming the metal film, it was covered with a metal film material that becomes a magnetic path and forms a magnetic field.
しかしながらこの磁気通路となる皮膜素材は磁

磁気記録を破壊する等の問題点があつた。 However, the film material that forms this magnetic path is made of soft iron, cobalt, nickel, etc., which have low magnetic resistance.
Since it is made of stainless steel, aluminum, and iron-based alloys that have high magnetic resistance, this coating material creates a thin magnetic field around the permanent magnet in the engagement tool, which may cause iron sand to be attracted to the coating surface, or When a card, magnetic tape, cash card, magnetic chip, etc. comes into contact with the film, the magnetic recording of the card is destroyed.

ものである。(Means for Solving the Problems) The present invention has been proposed in view of the above-mentioned situation, and is directed from one magnetic pole surface a to the other magnetic pole surface b.
A permanent magnet 1 with a hole 1b transparent or recessed toward the
Ferromagnetic protrusions 4 and 5 protruding from either or both of the ferromagnetic plate 2 attached to the magnetic pole face b and the ferromagnetic plate 3 attracted to the magnetic pole face a are provided in the hole 1.
In the engagement tool which is removably attracted to each other or the other ferromagnetic plate 2 or 3 within b, a metal coating 1 which is entirely or partially non-magnetic is provided on the circumferential surface of the permanent magnet 1.
By creating a magnetic space on the surface of the permanent magnet and eliminating the influence of magnetism, leakage occurs.As the number of lines of magnetic force decreases, magnetic flux gathers on the protruding parts and the attraction force becomes stronger. This is how it was done.

効果を得るものである。(Effect) The present invention consists of the characteristic structure described above,
In particular, a non-magnetic metal film 1a is formed on the entire circumferential surface of the permanent magnet 1 or on a part of the circumferential surface that is not covered with the ferromagnetic plate 2, case 6, etc. by electroplating or the like. By doing so, the following effects can be obtained.

In addition, the surface scratch resistance and abrasion resistance are significantly improved, and the surface gloss and color tone are improved, and the surface roughness of the permanent magnet 1 is eliminated, and the surface roughness associated with this surface roughness is improved. It is designed to completely eliminate infiltration and staining.

シユカードなどに影響がない。 In addition, since a magnetic space is formed around the permanent magnet 1 by the non-magnetic metal film, even if a magnetic recording object such as a magnetic chip, cassette tape, or cash card comes into contact with the permanent magnet 1, the magnetic recording part will not be affected. Magnetic disturbances such as destruction are alleviated,
If the leakage magnetic field lines are around 350 to 450 Gauss, there will be no effect on cash cards, etc.

る。 In addition, by creating a magnetic gap, the leakage of magnetic lines of force is reduced, so the ferromagnetic protrusion 4 has less magnetic resistance.
The magnetic force is concentrated in 5 parts, and the magnetic force can be significantly increased.In addition, in the case of fitting problems, the magnetic force is reduced due to misalignment of the magnetic surface, the vibration of the magnet, and the engagement tool. This definitely eliminates the bulk problem.
