절첩식 각도기 {PROTRACTOR} Folding Protractor {PROTRACTOR}

도 1은 본 고안의 바람직한 실시예에 따른 절첩식 각도기를 펼친상태를 도시하는 도면이다.1 is a view showing an unfolded state of the folding protractor according to a preferred embodiment of the present invention.

도 2는 도 1에 도시된 절첩식 각도기를 접은 상태를 도시하는 도면이다.FIG. 2 is a view showing a state in which the folding protractor shown in FIG. 1 is folded.

도 3은 본 고안의 바람직한 다른 실시예에 따른 절첩식 각도기를 도시하는 도면이다.3 is a view showing a folding protractor according to another embodiment of the present invention.

본 고안은 각도기에 관한 것이며, 더욱 상세하게는 각도가 표시된 다수개의 절편을 절첩식으로 구성하여 용이하게 펼치거나 접을 수 있음으로 휴대가 간편한 각도기에 관한 것이다.The present invention relates to a protractor, and more particularly to a protractor that is easy to carry because it can be easily unfolded or folded by configuring a plurality of fragments marked angle.

일반적으로, 각도기는 각의 크기를 재는 기구이며, 제도용 혹은 학습용으로 널리 사용된다.In general, protractors are instruments for measuring the size of an angle and are widely used for drafting or learning.

이러한 각도기는 통상적으로 원형 또는 반원형상의 플레이트이며, 그 가장자리에 눈금등을 이용하여 각도를 새긴 구조를 갖는다.Such protractors are typically circular or semi-circular plates, and have an angle-engraved structure at the edge thereof using a scale lamp.

따라서, 사용자는 이러한 각도기를 이용하여 두선이 이루는 각을 측정할 수 있다.Therefore, the user can measure the angle formed by the two lines using this protractor.

그러나, 이러한 각도기의 경우 그 크기로 인하여 주머니 등에 넣기 어려워 휴대가 불편한 문제점이 있다. However, such a protractor has a problem in that it is difficult to carry it due to its size and difficult to put in a pocket.

본 고안은 상기한 바와 같은 문제점을 해결하기 위하여 창안된 것으로 본 고안의 목적은 그 구조를 개선하여 펼치거나 접을 수 있도록 함으로써 휴대가 간편한 절첩식 각도기를 제공하는데 있다.The present invention was devised to solve the above problems, and an object of the present invention is to provide a folding protractor that is easy to carry by improving its structure so that it can be unfolded or folded.

상기의 목적을 달성하기 위하여, 본 고안의 바람직한 실시예는 일측 테두리에는 눈금이 표시됨으로써 각도를 표시하고, 타측에는 힌지홀이 형성된 다수개의 절편; 그리고 상기 힌지홀을 관통함으로써 상기 다수개의 절편을 힌지가능하게 고정하여 펼치거나 접을 수 있는 힌지핀을 포함하는 절첩식 각도기를 제공한다.In order to achieve the above object, a preferred embodiment of the present invention is to display the angle by displaying a scale on one side border, the other side is a plurality of sections formed with a hinge hole; And it penetrates through the hinge hole provides a folding protractor comprising a hinge pin that can be hinged to secure the plurality of pieces to expand or fold.

이하, 첨부한 도면을 참조하여 본 고안의 실시예에 따른 절첩식 각도기의 구조를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the structure of the folding protractor according to an embodiment of the present invention.

도 1은 본 고안의 바람직한 실시예에 따른 절첩식 각도기를 펼친상태를 도시하는 도면이고, 도 2는 도 1에 도시된 절첩식 각도기를 접은 상태를 도시하는 도면이다.1 is a view showing an unfolded folding protractor according to a preferred embodiment of the present invention, Figure 2 is a view showing a folded protractor shown in FIG.

도시된 바와 같이, 본 고안이 제안하는 절첩식 각도기(1)는 다수개의 절편(A,B)과, 다수개의 절편(A,B)을 회전가능하게 고정시키는 힌지핀(3)으로 이루어진다.As shown, the folding protractor 1 proposed by the present invention consists of a plurality of sections A and B and a hinge pin 3 to rotatably fix the plurality of sections A and B.

이러한 구조를 갖는 절첩식 각도기에 있어서, 상기 다수개의 절편(A,B)은 사각형상이며 일측에는 원주(7)가 형성된다. 그리고, 이 원주(7)에는 각도를 의미하는 눈금(5)이 새겨진다.In the folding protractor having such a structure, the plurality of pieces A and B are rectangular in shape and a circumference 7 is formed at one side. And the circumference 7 is engraved with the scale 5 which means an angle.

또한, 상기 다수개의 절편(A,B)들은 다양한 재질로 제조될 수 있지만, 예를 들면 플라스틱 혹은 투명한 필름지로 제조할 수 있다.In addition, the plurality of sections A and B may be made of various materials, for example, plastic or transparent film paper.

이러한 다수개의 절편(A,B)들은 타측에 힌지홀(h)이 형성되며, 상기 힌지홀(h)에는 힌지핀(3)이 관통된다.The plurality of pieces A and B have hinge holes h formed at the other side thereof, and hinge pins 3 are penetrated through the hinge holes h.

즉, 다수개의 절편(A,B)들의 하단부는 힌지핀(3)에 의하여 서로 고정됨으로써 다수개의 절편(A,B)들은 이 힌지핀(3)을 중심으로 회전이 가능하다.That is, the lower ends of the plurality of sections A and B are fixed to each other by the hinge pins 3, so that the plurality of sections A and B can be rotated about the hinge pins 3.

따라서, 상기 다수개의 절편(A,B)들을 힌지핀(3)을 중심으로 적절하게 펼치는 경우 각도기로 사용할 수 있다. 이때, 펼친 상태의 각도기(1)는 0도 내지 180도의 각도 범위를 갖는다. Therefore, the plurality of fragments (A, B) can be used as a protractor when properly spreading around the hinge pin (3). At this time, the protractor 1 in the unfolded state has an angle range of 0 degrees to 180 degrees.

반대로, 다수개의 절편(A,B)들을 접는 경우 도2 에 도시된 바와 같이 크기를 줄임으로써 보관이 편리하다.On the contrary, when folding the plurality of sections A and B, storage is convenient by reducing the size as shown in FIG.

한편, 도3 에는 본 고안의 바람직한 다른 실시예가 도시된다. 즉, 각도기를 펼친 경우, 각각의 절편(A,B)들이 움직이는 것을 방지하기 위하여 각각의 절편(A,B)에 삽입홈(9)을 형성한다.On the other hand, Figure 3 shows another preferred embodiment of the present invention. That is, when the protractor is unfolded, the insertion grooves 9 are formed in the respective sections A and B in order to prevent the respective sections A and B from moving.

즉, 일측 절편(A)의 일측면(11)에 삽입홈(9)을 형성하고, 이 삽입홈(9)에 이웃한 절편(B)의 측면(13)을 삽입하는 방식이다.That is, the insertion groove 9 is formed in one side surface 11 of one side fragment A, and the side surface 13 of the segment B adjacent to this insertion groove 9 is inserted.

이러한 방식에 의하여 모든 절편(A,B)들을 삽입홈(9)에 삽입함으로써 펼쳐진 형태의 각도기는 반원형상을 유지할 수 있다.In this way, by inserting all the sections A and B into the insertion groove 9, the protractor in the unfolded shape can maintain a semicircular shape.

이상 설명한 바와 같이 본 고안에 따른 절첩식 각도기는 다수개의 절편을 힌지가능하게 고정함으로써 필요시 펼치거나 접을 수 있어서 휴대가 간편한 장점이 있다.As described above, the folding protractor according to the present invention has the advantage of being easy to carry as it can be unfolded or folded as needed by fixing a plurality of pieces to be hinged.

또한, 각각의 절편에 삽입홈을 형성하여 이웃한 절편의 측면을 삽입함으로써 전체 각도기를 고정시킬 수 있는 장점이 있다.In addition, there is an advantage that can be fixed to the entire protractor by inserting the side of the adjacent section by forming an insertion groove in each section.
