본 고안은 공지의 각도기와 자를 결합하여 자도 사용하고 각도기의 각도선을 직접 그릴 수 있는 각도기와 자에 관한 것이다.The present invention relates to a protractor and a ruler that can be used in combination with a known protractor and ruler, and can directly draw the angle line of the protractor.
종래에는 자와 각도기가 분리되어 휴대하기와 사용하기 불편하던 것을 자의 한 몸체에 각도기를 합리적으로 결합하여 사용되는 본 고안을 설명하면 다음과 같다.Conventionally, when the ruler and the protractor are separated, the present invention is used to reasonably combine the protractor with one body of the ruler, which is inconvenient to carry and use.
본체(11)의 자눈금(2') 끝이 자사용선(2)에 접한 지점에서 각도기 중심점(1)으로 정하여 자사용선(2)의 상당이 각도기 눈금(1') 0도에서 하단이 180도선으로 사용되어 필요한 길이의 각도선을 그릴때는 자눈금(2')을 사용하며 자사용선(2)에 필요한 길이로 직접 각도선을 긋고 그어진선 한끝에 각도기 중심점(1)을 맞추며 필요한 각도눈금(1')도 맞춘다음 전과 같이 자 사용선(2)에 선을 그으면 필요한 각도선을 그을 수 있어 이와같은 방법으로 필요한 여러 직각형을 그릴 수 있고 여러 정다각형은 그 각형에 해당하게 변과 변이 접한 내각과 같은 각도로 자사용선(2)에서 각도 60도의 정 3각형선(3), 각도 90도의 정 4각형선(4), 각도 108도의 정 5각형선(5), 각도 120도의 정 6각형선(6), 각도 135도의 정 8각형선(8), 각도 140도의 정 9각형선(9), 각도 144도의 정 10각형선(10), 이 각도눈금(1')의 연장선으로 도면과 같이 배열표시 되었고 자눈금(2') 끝이 자사용선(2)에 접한(1") 지점에서 자사용선(2)에서 각도 128.57로 되게 정 7각형선(7)이 표시되어 1변의 길이를 필요한 길이로 정 3각형에서 정 10각형까지 직접 그릴수 있는 고안인 것이다.At the point where the end of the scale (2 ') of the main body (11) is in contact with the own line (2), the center of the protractor (1) is defined as the center point (1) .The equivalent of the own line (2) is 180 degrees from the bottom of the protractor scale (1') to 0 degrees. When drawing the angle line of the required length, use the ruler scale (2 '), draw the angle line directly to the length required for the user line (2), and align the center point (1) of the protractor at one end of the drawn line. ') And then draw a line on the user's line (2) as before, so that you can draw the necessary angle lines. In this way, you can draw the various right angles. At the same angle, the self-contained line (2) has a regular triangular line (3) with an angle of 60 degrees, a regular tetragonal line (4) with an angle of 90 degrees, a regular hexagonal line (5) with an angle of 108 degrees, and a regular hexagonal line with an angle of 120 degrees ( 6) a regular octagonal line (8) with an angle of 135 degrees, a regular pentagonal line (9) with an angle of 140 degrees, a regular pentagonal line (10) with an angle of 144 degrees, and It is an extension line of the scale (1 ') and is arranged as shown in the drawing, and the regular hexagonal line has the angle of 128.57 on the user's line (2) at the point where the end of the scale (2') is in contact with the line (2). (7) is indicated, and the length of one side can be drawn directly from the regular triangle to the regular hexagon with the required length.
예를 들면 그려진 정 6각형의 변과의 내각이 120도 이므로 한변의 길이가 4.8센치의 정 6각형을 그리려면 자눈금(2')을 사용하여 자사용선(2)에 4.8센치의 선을 긋고 그어진 이 선에 정 6각형선(6)을 맞추고 자사용선(2)에 4.8센치선을 그으면 변과 변의 내각이 각도 120도가 되는 4.8센치의 두 선이 그어진다.For example, to draw a square hexagon with a side length of 4.8 centimeters, draw a 4.8 centimeter line on the user's line (2) using the scale (2 '). Align this line with the regular hexagonal line (6), and draw a line of 4.8 centimeters on the line (2), which draws two lines of 4.8 centimeters where the sides and the angles of the sides are 120 degrees.
이와같이 정 6각형이 그려질때까지 반복하면 1변의 길이가 4.8센치되는 정 6각형이 그려지므로 이와 같은 방법으로 정 3각형에서 정 10각형까지 그릴 수 있다.Repeating until the regular hexagon is drawn in this way will draw a regular hexagon with a length of 4.8 centimeters on one side.
종래에는 각도기와 자가 분리되어 각도기를 사용하여 각도점을 찍고 이점에 자를 잘 맞추어 각도선을 그어야하는 불편함을 본 고안으로 각도기와 자를 합리적으로 도면과 같이 결합시켜 각도선을 그을때 직접 자선을 사용할 수 있어 자와 각도기 기능을 동시에 사용할 수 있는 각도기와 자의 고안인 것이다.Conventionally, the protractor and the self is separated from the angle point by using a protractor to draw the angle line in accordance with the advantages of the present invention inconvenient to draw the angle line by combining the protractor and the ruler as shown in the drawing, when drawing the angle line directly It is a device of a protractor and a ruler that can be used at the same time.
