Abstract
본 고안은 작은 각도기가 막대자 옆에 붙어 있어서 선을 그리기가 매우 쉽고 자와 각도기가 일체로 구비됨으로서 작업성을 향상시키고, 분실을 방지할 수 있는 효과가 있고, 작도할 때는 막대자를 이용하여 정확한 각도를 나타내는 표시를 할 수 있게되어 오차없이 작도를 할 수 있는 효과가 있다.The present invention has a small protractor attached to the side of the bar, so it is very easy to draw lines, and the ruler and protractor are integrated to improve workability and prevent loss. Since the angle can be displayed, the drawing can be made without error.
Description
본 고안은 막대자가 부설된 각도기에 관한 것으로서, 보다 상세하게는 각도기의 센터점에 회동되는 막대자를 부설하여 각도기를 이용하여 작도를 할 때 주어진 각도를 보다 용이하게 작도할 수 있도록 하는 막대자가 부설된 각도기에 관한 것이다.The present invention relates to a protractor in which a bar is installed. More specifically, a bar is installed to allow a user to construct a given angle more easily when constructing by using a protractor by laying a bar that is rotated at a center point of the protractor. It is about a protractor.
종래에 사용되는 각도기는 선분과 선분사이의 벌어져 있는 각도를 측정하기 위한 학습도구로서, 일반적인 구성은 투명한 재질을 이용한 평면형태의 반원형으로 제작되어, 밑변에는 수평선 및 센터점이 그려지고, 원주를 따라 각도를 나타내는 각도눈금이 그려진다.
Conventional protractor is a learning tool for measuring the gap between the line segment and the line segment, the general configuration is made of a semi-circle of a flat form using a transparent material, the horizontal line and the center point is drawn on the base side, the angle along the circumference An angle scale indicating is drawn.
상기와 같은 종래의 각도기를 이용하여 주어진 각도를 작도할 때는 각도기의 센터점에 기준점을 맞추고 주어진 각도를 각도기의 눈금에서 찾아 점을 찍어 표시한 다음 각도기를 치우고 기준점에서 자를 이용하여 선을 그어 각도를 그렸다.When constructing a given angle using the conventional protractor as described above, set the reference point to the center point of the protractor, find the given angle on the scale of the protractor, mark it and mark it, then remove the protractor and draw a line using a ruler at the reference point to adjust the angle. Painted.
그런데, 점을 찍어 눈금을 표시하고 다시 기준점과 선을 그어야 하다보니 작도과정에서 오차가 발생되는 문제점이 있었다. 또한 각도를 측정할 때, 각도기의 반지름보다 각도를 표시하는 표시점이 멀리있으면 그 표시점에서 각도기의 각도눈금까지 연장선을 그어 각도를 측정해야 하는 불편함이 있었다.However, there was a problem in that an error occurred in the drawing process because the point to mark the scale and draw the reference point and line again. In addition, when measuring the angle, if the mark indicating the angle is farther than the radius of the protractor, there was an inconvenience to measure the angle by drawing an extension line from the mark to the angle scale of the protractor.
또한, 이와 같이 분도와 직선을 작도하기 위하여 각도기 및 막대자는 제도과정에서 병용되는 경우가 대부분인데, 이러한 각도기와 막대자를 각각 별도로 사용할 경우 작업성이 저하됨은 물론 분실 등 사용상의 문제점을 안고 있었다.In addition, the protractor and the bar to be used in the drafting process in order to draw a straight line and a straight line as described above, when using the protractor and the bar separately, respectively, the workability is degraded, there are problems in use, such as loss.
본 고안은 상기와 같은 문제점을 해결하고자 안출된 것으로서, 본 고안의 목적은 각도기의 센터점에 막대자를 회동되도록 부착하여 주어진 각도를 작도할 때 상기 막대자를 이용하여 정확한 각도를 손쉽게 그릴 수 있도록 함으로서 사용상의 편의성 및 학습능률을 향상시키데 있다.
The present invention was devised to solve the above problems, and the object of the present invention is to attach the bar to the center point of the protractor so that it can easily draw the correct angle using the bar when drawing a given angle. To improve convenience and learning efficiency.
상기의 목적을 달성하기 위한 본 고안에 따른 막대자가 부설된 각도기는 반원형상으로 제작되어, 밑변에는 수평선 및 센터점이 그려지고, 원주를 따라 각도를 나타내는 각도눈금이 그려지는 각도기에 있어서, 상기 각도기의 센터점에는 리벳으로 결합되어 회동되는 막대자가 체결되되, 상기 막대자는 일변에 길이를 나타내는 눈금이 그려지고, 타변은 회동되어 상기 수평선과 일치되도록 구비되는 것을 특징으로 한다.According to the present invention, a protractor equipped with a bar bar according to the present invention for achieving the above object is manufactured in a semicircular shape, a horizontal line and a center point are drawn at the bottom, and an angle scale indicating an angle along the circumference is drawn. The bar is coupled to the center point is coupled to the rivet is rotated, the bar is characterized in that the scale indicating the length on one side is drawn, the other side is rotated to match the horizontal line.
또한, 상기 막대자의 양측에는 각도기의 높이만큼의 높이차를 보상하는 높이조절볼트가 각각 체결되는 것을 특징으로 한다.In addition, both sides of the bar is characterized in that the height adjustment bolt to compensate for the height difference by the height of the protractor, respectively.
본 고안에 따른 막대자가 부설된 각도기는 자와 각도기가 일체로 구비됨으로서 작업성을 향상시키고, 분실을 방지할 수 있는 효과가 있고, 작도할 때는 막대자를 이용하여 정확한 각도를 나타내는 표시를 할 수 있게되어 오차없이 작도를 할 수 있는 효과가 있다.Protractor with bar bar according to the present invention is provided with a ruler and a protractor integrally to improve workability, to prevent the loss, and when drawing, it is possible to display the exact angle using the bar There is an effect that can be drawn without error.
또한, 각도기의 반지름보다 표시점이 멀리있어 그 각도를 정확히 측정할 수 없을때도 막대자를 이용하여 정확한 각도를 측정할 수 있는 효과가 있다.In addition, even when the display point is far from the radius of the protractor, the angle can be measured accurately using the bar when the angle cannot be measured accurately.
도 1은 본 고안에 따른 막대자가 부설된 각도기를 나타내는 사시도이고,1 is a perspective view showing a protractor bar is installed according to the present invention,
이하, 본 고안에 따른 막대자가 부설된 각도기에 대하여 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings for the protractor bar is installed according to the present invention in detail as follows.
