본 고안은 각도기와 자가 분리되여 사용하던것을 자눈금과 각도눈금을 결합한 각도기 겸용자에 관한것이다.The present invention relates to a protractor combined with a ruler and an angular scale that was used separately from the protractor.
종래에 각도기와 자를 각각 사용하여야 하는 불편을 자와 각도기를 합리적으로 결합하여 자와 각도기를 각각 사용할수도 있고 동시에 사용할수도 있도록 형성된 본 고안을 도면에 의하여 설명하면 다음과 같다.Conventionally, the inconvenience of having to use a protractor and a ruler by reasonably combining the ruler and the protractor can be used by the ruler and the protractor, respectively.
각도 10도 단위인 각도선(4')(5)(6)(7)(8)(9)에 해당하는 각도1도 간격으로 40도에서 90도까지의 각도선 한쪽끝이 각각 자사용선(11)에 접한지점(11")의 간격도 자눈금(11') 한쪽끝이 자사용선(11)에 접한 간격과 동일하여 자사용시 자눈금을 사용할때 자눈금과 동일하게 자눈금으로 사용되고 자사용선(11) 반대 방향의 각도선의 간격은 자눈금(11') 간격과 다르나 각도선 양쪽의 자눈금(11') 길이와 같게 직선으로 자사용선(11)과 평행하게 자눈금과 같은 형태로 각도선이 표시되어 아무런 불편없이 자눈금(11')과 동일하게 자눈금으로 사용할 수 있게 되었다.One end of each angle line from 40 degrees to 90 degrees at an angle of 1 degree corresponding to the angle lines 4 ', 5, 6, 7, 8, and 9, each unit of 10 degrees, 11) The distance between the point of contact (11 ") is also equal to the gap between one end of the scale (11 ') and the own line (11). (11) The spacing of the angle line in the opposite direction is different from the spacing of the scale (11 '), but is the same as the length of the scale (11') on both sides of the angle line. It is displayed and can be used as the scale without any inconvenience as the scale (11 ').
투명한 자의 본체(12)에 각도기 중심점(10)을 중심으로 각도 0도에서 40도까지 각도 10도 단위인 10도선(1), 20도선(2), 30도선(3), 40도선(4)과 각도 40도에서 180도까지의 각도눈금(10')으로 종래의 방법으로 각도기 사용의 각도를 잴수 있으며 각도 0도에서 40도와 반대방향으로 140도에서 180도 까지만 자의 본체한쪽 끝단까지 각도눈금이 표시되어 종래의 각도기 사용과 같이 각도점을 표시 할수 있는 상태가 된다.10-degree line (1), 20-degree line (2), 30-degree line (3), 40-degree line (4) in the unit of a transparent ruler (12) centered on the protractor center point (10) from 0 to 40 degrees With the angle scale (10 ') from 40 degrees to 180 degrees, the angle of use of the protractor can be measured by the conventional method, and the angle scale up to one end of the main body of the body only from 140 degrees to 180 degrees in the opposite direction from 0 degrees to 40 degrees. In this state, the angle point can be displayed as in the conventional protractor.
각도선 사용시 각도선이 길어야 정확히 사용할 수 있어 연장 각도선 (4")(5')(6')(7')(8')(9')은 순서대로 각도선(4')(5)(6)(7)(8)(9)의 연장선으로 사용된다.When using angle line, the angle line should be long so that it can be used correctly. The extension angle line (4 ") (5 ') (6') (7 ') (8') (9 ') has the angle line (4') (5) (6) (7) (8) (9) is used as an extension line.
여러 각도선이 각각 자사용선(11)에 접한지점(11")를 중심으로 상단방향으로 자사용선(11)과의 각도는 1도간격으로 40도에서 90도까지의 10도 단위로 각도선(4'.4")(5.5')(6.6')(7.7')(8.8')(9,9')이 배열표시되여 이 여러 각도선들이 자사용선(11)에 접한 지점(11") 하단 방향으로 자사용선(11)과의 각도는 90도에서 140도까지 사용된다.The angle with the self-use line 11 in the upper direction centering on the point 11 " where each of the angle lines abuts the self-use line 11 is an angle line in 10-degree increments from 40 to 90 degrees at an interval of 1 degree. 4'.4 ") (5.5 ') (6.6') (7.7 ') (8.8') (9,9 ') are arranged to show the bottom of the point (11") where these angled lines are in contact with self line 11 The angle with the self-use line 11 in the direction is used from 90 degrees to 140 degrees.
여러 각도선을 자와 결합하여 사용할 수 있는 설명을 하나의 각도선 (6.6')만을 예로 설명하기로 한다.A description that can be used by combining several angle lines with a ruler will be described with only one angle line 6.6 '.
각도선(6,6')이 자사용선(11)에 접한 지점에서 상단 방향으로 자사용선(11)과의 각도는 60도가 되고 하단 방향으로는 각도 120도가 되므로 자를 사용하여 1차로 5센티의 선을 긋고 그어진 선위에 투명한 자의 각도선(6,6')이 일치하도록 맞춘다음 자사용선(11)에 각도선(6,6)이 접한 지점에서 상단방향으로 2차로 5센티의 선을 긋고 한번 더 반복하면 1변의 길이가 5센티의 정3각형이 그려지고 이와같은 방법으로 반대방향으로 반복 사용하면 내각이 120도되는 정6각형이 그려진다.When the angle line 6,6 'is in contact with the line 11, the angle with the line 11 is 60 degrees in the upper direction and 120 degrees in the lower direction. Draw a line and align the line (6,6 ') of the transparent ruler on the drawn line and draw a line 5 centimeters in the upper direction from the point where the line (6,6) is in contact with the line (11). If you repeat, a square of 5 centimeters in length will be drawn, and if you use it in the opposite direction in this way, the square will be drawn as 120 degrees.
사용 설명과 같이 그리고져 하는 각도에 해당하는 각도선에 1변의 길이를 필요한 길이만큼 자눈금을 직접 사용하며 각도선을 그리고 여러 정각형과 직각형을 그릴수 있고 각도기와 자를 각각 사용할수도 있으며 동시에 사용할 수 있는 편리한 고안인 것이다.You can use the ruler directly on the angle line corresponding to the angle you want to draw as long as you need, draw angle lines, draw multiple squares and right angles, and use protractors and rulers, respectively. It is a convenient design.
