본 고안은 컴퓨터, 각종 전자기기등의 입력장치용으로 사용되는 키이보오드에 관한 것이다.The present invention relates to a key board used for an input device such as a computer, various electronic devices, and the like.
키이보오드는 하판(下板)위에 소정간격으로 맴브레인(membrane) 또는 기계적인 스위치부가 다수 병설된다. 상판에는 이들 스위치부의 상하를 향해 상하진퇴가 자유로운 복수의 키이부가 설치된다.The key board is provided with a plurality of membranes or mechanical switches on the lower plate at predetermined intervals. The upper plate is provided with a plurality of key portions freely moving up and down toward these switches.
이 키이부의 톱(top)을 손가락으로 누르면 일체의 키이스템(key stem)이 상기 스위치부를 개폐한다.When the top of the key portion is pressed with a finger, an integral key stem opens and closes the switch portion.
표준키이부의 톱은 1변이 약 18mm의 대략 정방형을 이루고 있지만 사용빈도가 높은 키이 또는 특수용도의 키이는 표준키이에 비해 길쭉한 것, 수배 큰 것등이 있다. 이와같은 특수한 모양의 키이, 예를 들어 길쭉한 키이에 있어서, 종래는 제6도의 정면도와 제7도의 측면도에 도시한 바와같이 길쭉한 키이부(1)의 대략 중앙에 1개의 키이스템(10)과 1개의 스위치부(2)를 설치했을 뿐이었다.The top of the standard key part is approximately 18mm on one side, but the key with high frequency or special purpose is longer or several times larger than the standard key. In such a specially shaped key, e.g., an elongated key, one kistem 10 and one in the center of the elongated key part 1 as shown in the front view of FIG. 6 and the side view of FIG. Only two switch sections 2 were provided.
그래서, 다른 형상이 키이부(1)나 스위치부(2)로 변경할 수가 없었다.Thus, the other shape could not be changed to the key portion 1 or the switch portion 2.
또 특수형상의 키이에서는 키이톱(3)의 어느 위치를 눌러도 전체가 균일하게 내려 눌려지도록 하는 것이 요구되지만, 그 목적때문에 제6도의 예에서는 크랭크모양의 연동봉(4)을 장착하여 우측 끝의 화살표의 위치를 눌렀을때, 연동봉(4)으로 키이톱(3)의 다른쪽 끝도 동시에 내려눌러지도록 하여, 쇄선과 같이 비스듬하게 내려눌려지는 것을 방지하고 있었다.In addition, in the special shape of the key, it is required to press down the entire position of the key top 3 evenly, but for this purpose, in the example of FIG. 6, the crank-shaped interlocking rod 4 is attached to the right end. When the position of the arrow was pressed, the other end of the key top 3 was also simultaneously pushed down by the interlocking rod 4 to prevent the slant from being pushed down like a chain line.
그리고 (5)는 상판, (6)은 하판, (7)은 연동봉지지체이다.And (5) is an upper plate, (6) is a lower plate, and (7) is an interlocking rod support.
제6도와 같이 키이부(1)의 중앙에 스위치부(2)를 설치한 키이보드에서는 설계시점에서 키이의 크기, 키이의 배열이 결정되어, 범용성이 없고 키이의 크기나 키이의 배열에 변경이 생겨도 변경을 할 수 없다.As shown in FIG. 6, the key board in which the switch unit 2 is installed in the center of the key unit 1 determines the size of the key and the arrangement of the keys at the design time. You cannot change even if you do.
이때문에 목적에 따른 키이부, 스위치부, 상판, 하판, 연동봉 기타의 부품을 많은 종류 준비해 두어야 하므로 매우 비경제적일 뿐만아니라 다수의 부품을 장착해야 하므로 조립공수가 많아진다는 등의 문제가 있었다.For this reason, the key part, the switch part, the upper plate, the lower plate, the interlocking rod, etc. according to the purpose have to prepare many kinds of parts, which is not only very economical, but also requires the installation of a large number of parts, there is a problem of increasing the number of assembly labor.
본 고안의 제1의 목적은 키이의 크기, 키이의 배열등에 변동이 생기거나, 기종이 다른 키이보오드 이더라도 공통의 키이브오드로 구성할수 있는 이른바, 범용성이 있는 키이보오드를 얻는데 있다.The first object of the present invention is to obtain a so-called universal key board which can be configured with a common key board even if the size of the key, the key arrangement, etc. fluctuate, or different types of key boards.
본 고안의 제2의 목적은 키이위치, 키이의 크기등을 변경할 경우, 키이부만을 다시 꽂는 것만으로 할 수있는 것을 얻는데 있다.A second object of the present invention is to obtain a thing that can be done only by reinserting the key part when changing the key position, key size, and the like.
본 고안의 제3의 목적은 부품을 공통화하여 가능한 부품점술 줄이는데 있다.A third object of the present invention is to reduce parts occupancy by making parts common.
본 고안의 또다른 목적과 특징은 다음의 실시예의 설명에 의해 더한층 명백해진다.Still other objects and features of the present invention will become apparent from the following description of the embodiments.

이 키이톱(3)의 크기와 형상은 세로와 가로의 길이를 a의 정수배로 하는것을 조건으로 하며, 다시 길쭉한것, 큰것, L자형의 것, ㄷ자형의 것등 사용목적에 따라 결정된다. 상기 제3도에 도시한 단위크기의 키이부(1)는 키이톱(3)의 하면 중앙에 원통형의 키이스템(10)을 갖는다.The size and shape of the key top 3 are subject to the length of the length and width being an integer multiple of a, and again determined according to the purpose of use such as elongated, large, L-shaped, and c-shaped. The key portion 1 of the unit size shown in FIG. 3 has a cylindrical key system 10 at the center of the bottom surface of the key top 3.
이 키이스템(10)의 중심공에는 제2도 좌측의 키이스템(10)과 같이, 하판(6)상의 스위치부(2)를 개폐하는 코일스프링(11) 이 압입되며, 또 외주에는 제2도 우측의 키이스템(10)과 같이, 키이부(1)를 윗쪽으로 들어 올리는 코일스프링(12)이 개장되어 있다.The coil spring 11 for opening and closing the switch part 2 on the lower plate 6 is press-fitted into the center hole of the kiss system 10, like the kiss system 10 on the left side of FIG. Like the kistem 10 of FIG. Right side, the coil spring 12 which raises the key part 1 upward is retrofitted.
또 키이톱(3)의 하면에는 키이스템(10)을 중심으로 하여 180도의 점대칭으로 하여 발지편(13)(13)이 앞끝에 걸림용 돌출부(14)(14)를 가지고 설치되어 있다.Moreover, the lower surface of the key top 3 is provided with the locking projections 14 and 14 at the front-end | tip with 180-point point symmetry centering on the key 10. As shown in FIG.
그리고 다른 180도의 점대칭 위치에도 원주(15)(15)가 식립(植立)되어 있지만 이것은 생략해도 된다.And although the circumference 15 (15) is implanted in another 180 degree point symmetry position, you may abbreviate | omit it.
이와같이 해서 형성된 단위크기의 키이부(1)는 상판(5)의 키이스템안내공(8)과 발지안내공(9)에 끼워넣어진다.The key portion 1 of the unit size formed in this manner is fitted into the key guide hole 8 and the retaining guide hole 9 of the upper plate 5.
끼워넣는 방향은 90도의 간격으로 바꿀 수 있다.The embedding direction can be changed at intervals of 90 degrees.
제4도의 키이부(1)는 상술한 바와같이 구형이며 또한 단위크기의 2배면적의 경우The key portion 1 of FIG. 4 is spherical as described above and in the case of twice the area of the unit size.
이 예의 경우, 2개의 키이스템(10)(10)이 키이스템안내공(8)(8)과 등간격으로 설치되어 있다.In this example, two kisses 10 and 10 are provided at equal intervals with the kiss guides 8 and 8.
그리고 2개의 키이스템(10)(10)중, 스위치부(2)를 누르지 않는 것은 약간 가늘게 형성하고, 키이스템안내공(8)(8)의 간격과 키이스템(10)(10)의 간격과의 사이에 오차가 있더라도 원활하게 상하운동하도록 되어 있다.Of the two kisses 10 and 10, the one that does not press the switch unit 2 is formed to be slightly thin, and the space between the kiss guides 8 and 8 and the space between the kisses 10 and 10. Even if there is an error between and it is to move up and down smoothly.
또 이 제4도에 도시한 2배면적의 키이부(1)에서는 하나의 키이스템(10)에 대해 2개씩의 발지편(13)을 점대칭위치에 180도 간격으로 설치하고, 제3도에 도시한 원주(15)는 설치하지 않는다.In addition, in the key portion 1 of the double area shown in FIG. 4, two retaining pieces 13 are provided at a point symmetrical position by 180 degrees with respect to one key system 10. The illustrated circumference 15 is not provided.
제5도의 키이부(1)는 상술한 바와같이 정방형이며, 단위크기의 4배면적의 경우이다.The key portion 1 in FIG. 5 is square as described above, and is four times the area of the unit size.
이 예의 경우, 4개의 키이스템(10)이 설치되며 또 발지편(13)은 하나의 키이스템(10)에 대해 1개씩으로 한다.In the case of this example, four kisses 10 are provided, and the retaining pieces 13 are made one by one for the kisses 10.
4개의 키이스템(10)중 180도의 간격을 둔 2개의 키이스템(10)(10)에 각기 코일스프링(11)(12)이 개장된다.Coil springs 11 and 12 are respectively installed in two kisses 10 and 10 spaced 180 degrees out of four kisses 10.
키이톱(3)의 형상이 더욱 길쭉한 것, L자형의 것, ㄷ자형의 것, 기타의 키이부에 대해서도 상기와 대략 같은구성이다.The shape of the key top 3 is longer, the L-shaped, the U-shaped, and the other key portions have the same configuration as described above.
이와같은 구성에 있어서, 각 형상의 키이부(1)를 키이스템안내공(8)과 발지안내공(9)에 맞추어서 찔러 넣으면 발지편(13)이 발지안내공(9)에 걸어맞추어 부착된다.In such a configuration, when the key portions 1 of each shape are inserted in accordance with the kistem guide hole 8 and the gripping guide hole 9, the gripping piece 13 is engaged with and attached to the gripping guide hole 9. .
이상과 같이 키이보오드는 상판의 키이스템 안내공의 X축방향의 간격과 Y축방향의 간격을 같게 하고, 또 키이부는 세로오 가로의 길이를 단위 길이의 정수배로 했으므로, 키이배열을 자유롭게 설정할 수 있다.As described above, the key board is equally spaced in the X-axis direction and the Y-axis direction of the top guide guiding hole of the top plate, and the key part has a vertical length equal to an integer multiple of the unit length. have.
또 일단 부착한 다음에 키이위치를 변경할 경우, 키이 보오드를 분해하지 않고 키이보오드 상면으로부터 키이부를 다시 꽂는 것만으로 할 수 있다.If the key position is changed after the attachment, the key portion can be reinserted from the top surface of the key board without disassembling the key board.
