4 : 자기실드판4: Magnetic shield plate
본 고안은 지갑에 관한 것으로 상세하게는 자기차폐구조를 갖는 지갑에 관한 것이다.The present invention relates to a wallet, and more particularly to a wallet having a magnetic shield structure.
종래로부터 일본공개실용신안공보 소55-5579호의 같은 각종 지갑구조가 통용되어 오고 있으나, 이와같은 지갑구조는 자력의 영향으로 자기기록이 변형되는 지하철승차권이나 은행카드 등을 보호하기 위한 보호수단이 강구되지 않아 많은 문제점이 있었다. 즉, 지하철 승차권이나, 크레디트카드등은 강한 자력을 내는 기기에 접촉되면 자기기록의 변형을 일으킴으로서 쉽게 사용불능으로 되는 일이 빈번하였다.Conventionally, various wallet structures such as Japanese Utility Model Publication No. 55-5579 have been commonly used, but such a wallet structure has a protective means for protecting subway tickets and bank cards, etc., in which magnetic records are deformed under the influence of magnetic force. There were not many problems. That is, subway tickets, credit cards, and the like frequently become inoperable by causing deformation of magnetic recordings when they come into contact with devices that generate strong magnetic force.
또한, 자기기록매체의 일종인 자기디스크의 경우에는 자기차폐재료로 된 디스크 홀더로서 자기기록 디스크를 보호하고 있으므로 자기차폐효과를 얻을 수 있기 때문에 이와같은 자기차폐수단을 지갑이나 승차권케이스 등에 적용하려는 시도가 있었다.In addition, in the case of a magnetic disk, which is a kind of magnetic recording medium, a magnetic holder is used to protect the magnetic recording disk. Therefore, the magnetic shielding effect can be obtained. There was.
그것은 공개실용신안공보 제88-5774호에서 보여주는 바와같이 강판과 종이를 일체로 반복시키되 강판의 두께를 조절하여 외부자력으로부터 내부자기기록매체를 보호하고자 하는 것이었으나, 자력의 강도에 맞추어 강판을 조절한다는 기술수단의 실시가 어렵고 실제실시효과 역시 의문스러운 문제점이 있어서 실용화되지 못하고 있었다. 즉 이와 같은 자기기록매체가 외부자력으로부터 차폐되기 위해서는 강한 자계로부터 충분한 자력의 유도를 일으켜야 하나, 강판이나 철합금의 경우에는 약 300의 비투자율을 가지므로 자계강도의 약 500이상을 갖는 완구용의 자석, 화학섬유, 헤드폰등으로부터 발생되는 자력으로부터는 자기유도되지 못하므로 내부자기기록매체에 그대로 자력이 미쳐 결국 차폐되지 못하고 내부 자기기록매체의 자기기록을 변형시키게 되며, 더우기 이와같은 지갑이나 통장 등이 가장 많이 휴대되는 핸드백에서는 700-1500의 자계강도를 갖는 부속이 대부분이어서 위와같은 강판이나 철합금의 재료로는 차폐효과를 전혀 얻을 수가 없었다. 즉, 충분한 차폐효과를 얻기 위해서는 비교적 비투자율이 높은 규소강이나 니켈합금의 퍼말로이 등을 사용할 것이 필요로 된다.It was intended to protect the internal magnetic recording medium from external magnetic force by repeating the steel sheet and paper integrally as shown in Korean Utility Model Publication No. 88-5774, but by adjusting the thickness of the steel sheet. It is difficult to implement the technical means, and the practical effect has also been questioned, and thus has not been put to practical use. In other words, in order for the magnetic recording medium to be shielded from external magnetic force, it is necessary to induce sufficient magnetic force from the strong magnetic field, but in the case of steel sheet or iron alloy, it has a specific permeability of about 300. Since magnetic force is not induced from magnets, chemical fibers, headphones, etc., the magnetic force is intact on the internal magnetic recording media, which is not shielded, and deforms the magnetic recording of the internal magnetic recording media. Most of these handbags have a magnetic strength of 700-1500, and most of them have no shielding effect. In other words, in order to obtain a sufficient shielding effect, it is necessary to use a relatively high permeability of silicon steel or a nickel alloy permloy.
본 고안은 실생활물품에서 흔하게 발생되는 500이상의 외부자력으로부터 자기차폐되는 지갑을 제공함에 그 목적이 있다. 이와 같은 목적을 달성하기 위하여 본 고안은 자계강도가 500이상의 높은 자성재료로 된 자기 실드판을 지갑의 내, 외피에 구성하여, 완구용 자석, 화학섬유, 헤드폰 등에서 발생되는 500이상의 자계강도를 차폐하고, 700- 1500정도의 핸드백 부품으로부터 차폐되도록 하는 특징이 있다.The object of the present invention is to provide a wallet that is self-shielded from more than 500 external magnetic forces commonly generated in real life products. In order to achieve the above object, the present invention constructs a magnetic shield plate made of a magnetic material having a magnetic field strength of 500 or higher on the inside and an outer surface of a purse to shield the magnetic field strength of 500 or more generated from a toy magnet, chemical fiber, and headphones. And shields from 700-1500 handbag parts.
첨부도면에 의거 더욱 상세히 설명하면 다음과 같다.According to the accompanying drawings in more detail as follows.
본 고안은 지갑(1)의 내, 외피 (2) (3)각각에 비투자율이 500이상인(강판의 경우 300이므로 그보다 훨씬 높아야 완구용 자석이나, 헤드폰의 자력으로부터 차폐되기 때문임)자성재료로 된 자기 실드판(4)을 구성하여서 된다.The present invention is a magnetic material with a specific permeability of 500 or more (300 in case of steel sheet, which is much higher than that because it is shielded from the magnetic force of a toy magnet or headphones) in the inner and outer shells of the wallet (1). The magnetic shield plate 4 may be configured.
미설명 부호 5는 자석, 6은 카드이다.Reference numeral 5 is a magnet, 6 is a card.
이와 같이 구성된 본 고안은 제 3 도에 도시한 바와 같이 지갑(1)에 완구용 자석등의 자석(5)이 근접되더라도 자기실드판(4)이 500이상의 자계강도를 가질 수 있는 규소강, 니켈합금 등의 자성재료로 구성되어 있으므로 완구용 자석이 통상 발휘하고 있는 자력의 영향을 차폐하게되어 지갑(1) 내부의 자기기록카드 등이 충분히 보호되는 것이다.The present invention configured as described above is made of silicon steel and nickel such that the magnetic shield plate 4 may have a magnetic field strength of 500 or more even when the magnet 5 such as a toy magnet is close to the wallet 1 as shown in FIG. 3. Since it is made of magnetic material such as an alloy, it is possible to shield the influence of the magnetic force normally exhibited by the toy magnet, so that the magnetic recording card or the like inside the wallet 1 is sufficiently protected.
종래에 알려진 일반적인 지갑의 구조로는 이와같은 차폐효과가 전혀 없어서 이를 개선하기 위하여 약 300의 비투자율을 갖는 강판으로 된 것이 시도된 적이 있으나, 강판의 투자율로는 완구용 자석과같은 비교적 적은 자계강도의 자력에 의해서도 쉽게 내부자기기록 카드가 변형되는 문제점이 있었으나, 본 고안은 자계강도가 500 이상의 자성재료로서 충분히 차폐효과를 얻을 수 있게 되는 것이다. 뿐만 아니라 본 고안은 자성재료를 금속박막위에 도포하여 지갑(1)의 내, 외피내측에 충착시켜서도 실시가 가능하다.Conventionally known wallet structures have no shielding effect at all, and in order to improve them, a steel sheet having a specific permeability of about 300 has been attempted. However, the magnetic permeability of the steel sheet has a relatively low magnetic strength such as a toy magnet. There is a problem that the internal magnetic recording card is easily deformed even by the magnetic force of the magnetic field. In addition, the present invention can be carried out by applying a magnetic material on the metal thin film to adhere to the inside of the wallet (1), the inner skin.
