본 고안은 텔레비젼이나 오디오 등 전자제품의 미조정부를 덮고있는 문의 개폐장치에 관한 것이다.The present invention relates to a door opening and closing device that covers the fine adjustment of electronic products such as television and audio.

더 상세히는 문의 개폐장치에 있어서, 1개의 영구자석과 1개의 전자석을 이용하여 이들이 마주보는 자극이 같은 극성으로 되어질때 발생하는 척력(斥力)으로 문이 열리도록 하고, 전자석이 여자(勵磁)되지 않을 때에는 전자석의 철심과 영구자석의 인력(引力)으로 문이 닫혀 있도록 하는 것인바 특히 원터치 방식으로 간단히 개폐되는 장치인 것이다.More specifically, in the door opening and closing device, using one permanent magnet and one electromagnet, the door is opened by the repulsive force generated when the magnetic poles facing each other become the same polarity, and the electromagnet is excited. If not, the door is closed by the electromagnet's iron core and the permanent magnet's attraction.

전자제품의 미조정부를 개폐하는 문은 그 개폐조작에 따라 여러가지 방식으로 구분되는데 특히 원터치 방식이 그 주종을 이루고 있다.Doors for opening and closing the unadjusted parts of electronic products are classified into various methods according to the opening and closing operation, and one-touch method is mainly used.

그 이유로서 조작이 간편하고 외관을 스마트하게 장식할 수 있다는 점이다.The reason is that the operation is simple and the appearance can be decorated smartly.

그런데 종래의 문에 구비되는 원터치 방식의 푸쉬 록킹 장치는 제품의 단가가 비싼데다가 구성이 복잡하고 잦은 취급으로 인하여 고장이 빈번하기 때문에 그 수명이 짧고 신뢰성이 낮은 결점이 있다.However, the one-touch push locking device provided in the conventional door has shortcomings of low cost and low reliability because of the high cost of the product and frequent failure due to the complicated configuration and frequent handling.

더욱이 문의 닫힌 상태를 유지하기 위한 훅크 부위가 파손되면 문을 개폐시키고자 하는 것인바 그 장치가 극히 간단하고, 고장발생이 없는 반영구적인 문 개폐장치를 제공하는 데 목적이 있다.Furthermore, if the hook part for maintaining the closed state of the door is broken, the door is to be opened and closed. The device is extremely simple, and an object of the present invention is to provide a semi-permanent door opening and closing device without a failure.

이하, 첨부된 도면을 참조하면서 본 고안의 구체적인 내용을 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described the specific contents of the present invention.

본 고안 장치의 구성은 제1도와 같이 제품 캐비넷의 미조정부에 구성된 문 개폐장치에 있어서, 캐비넷(1)의 미정부(2) 내측 상면에 리브(3)를 형성하여 이에 철심(4) 주위로 코일(5)이 감긴 전자석(M)을 장착하되 코일(5) 일단은 캐비넷(1) 일측에 돌출된 푸쉬버튼(6) 스위치(SW)의 접점을 통하여 전원(E)에 연결하고, 문(7) 상단 내측면에는 또 다른 리브(8)를 형성하여 이에 영구자석(9)을 장착하되 이 영구 자석과 마주보는 상기 영구 자석이 여자될때 서로 같은 극성(N극 또는 S)으로 되도록 하여 된 것이다.The structure of the device of the present invention is a door opening and closing device constituted in the fine adjustment portion of the product cabinet as shown in FIG. 1, in which a rib 3 is formed on the upper surface of the inside of the U.S. Mount the electromagnet (M) wound (5), one end of the coil (5) is connected to the power source (E) through the contact of the push button (6) switch (SW) protruding on one side of the cabinet (1), the door (7) On the inner side of the upper side, another rib 8 is formed so that the permanent magnet 9 is mounted thereon, and the permanent magnets facing the permanent magnets have the same polarity (N pole or S) when they are excited.

이와같은 본 고안 장치의 작용을 제2도 및 제3도를 보면서 설명하면, 제2도의 실선부분과 같이 닫혀있는 상태는 평상시 스위치(SW)는 오프되어 있어서 전원(E)이 차단된 상태이므로 전자석(M)의 코일(5)은 여자되지 않는다.Referring to FIG. 2 and FIG. 3, the operation of the device of the present invention will be described in the state of closing as shown by the solid line of FIG. 2, since the switch SW is normally turned off and the power source E is cut off. Coil 5 in M is not excited.

따라서 전자석(M)의 철심(4)을 자극을 띠지 않고 다만 철심과 문(7)의 영구자석(9) 사이에 인력이 작용하므로 문(7)은 닫혀있게 된다.Therefore, the magnetic core (4) of the electromagnet (M) is not stimulated, but the attraction force between the iron core and the permanent magnet (9) of the door (7) the door 7 is closed.

이러한 상태에서 문(7)을 열기 위해 푸쉬버튼(6)을 누르면 그 스위치(SW)의 접점이 온되어 전원(E)에 의해 코일(5)이 여자된다.In this state, when the pushbutton 6 is pressed to open the door 7, the contact point of the switch SW is turned on, and the coil 5 is excited by the power source E.

따라서 철심(4)은 자극을 띠게 되는데 이때의 극성은 마주보고 있는 영구자석(9)의 극성과 같은 극성이 되므로 순간적으로 척력이 작용한다.Therefore, the iron core (4) is a stimulus, the polarity at this time becomes the same polarity as the polarity of the permanent magnet (9) facing the moment the repulsive force acts.

그러므로 이 척력에 의해 닫혀있던 문(7)이 열리게 된다.Therefore, the door 7 that was closed by this repulsive force is opened.

누루고 있던 푸쉬버튼(6)을 놓으면 철심(4)은 자극을 잃는다.Release the push button 6, the iron core 4 loses irritation.

이후 문(7) 닫고자 하여 문(7) 밀면 문(7)의 영구자석(9)은 자극을 띠지 않은 철심(4)에 인력이 작용하므로 문(7)이 닫혀있게 된다.Since the door 7 is pushed to close the door 7, the permanent magnet 9 of the door 7 acts on the iron core 4 that is not stimulated so that the door 7 is closed.

즉, 문(7)은 푸쉬버튼(6)을 누루기 전에는 문(7)이 임의로 열리지 않는다.That is, the door 7 does not open arbitrarily until the door 7 is pressed.

또한 전자석(M)은 푸쉬버튼(6)을 누루는 순간만 동작하는 것이므로 전력소비도 극히 작은 것이다.In addition, the electromagnet (M) is operated only at the moment of pressing the push button 6, so the power consumption is extremely small.

이상과 같이 본 고안 장치에 의하면 원터치로 동작하는 문의 개폐장치를 전자적인 장치로 극히 간단하게 할 수 있고, 개폐동작이 원활하게 이루어지며 고장 발생이 없는 반영구적이어서 제품의 신뢰도를 향상시킬 수 있는 것이다.As described above, according to the device of the present invention, the door opening and closing device which operates with one touch can be made extremely simple with an electronic device, and the opening and closing operation is made smoothly.
