본 고안의 하나의 교구로 분도기와 자 및 콤퍼스의 기능을 할 수 있도록 복합기능을 지닌 다목적 교구에 관한 것이다.One parish of the present invention relates to a multi-purpose parish with a complex function to function as a protractor, ruler and compass.

종래의 경우 여러교구 중 막대자 혹은 분도기 및 콤퍼스 등을 개별구입하여 각각의 사용기능에 알맞는 교구를 선택사용하게 되었으므로 학생들의 경우는 많은 교구를 개별 구비하는데 있어서 경제적인 부담과 휴대하는데 있어 많은 불편이 있었다.In the conventional case, a rod or a protractor and a compass are individually purchased among various teaching tools to select and use a teaching tool suitable for each use function. There was inconvenience.

따라서 본 고안은 이와 같은 종래의 불편을 해소시키기 위해 일체형으로된 하나의 교구로 막대자, 분도기, 콤퍼스의 기능을 겸할 수 있도록 한 것으로서 첨부된 도면에 따라 그 구성 및 작용효과를 상세히 설명하면 다음과 같다.Therefore, the present invention is to be able to combine the functions of a bar, protractor, and compass as a single teaching aid to solve the conventional inconvenience as described in detail the configuration and effect according to the accompanying drawings Same as

일단부에는 체결공(1)을 가진 분도기(2)가 형성되고 상부로 안내레일(3)이 돌설됨과 장홀(4)이 투공된 막대자(5)의 안내레일(3)에 조립공(4)과 조임볼트(7) (7')가 체결되는 유동홀더(8)의 안내홈(9)을 끼워맞춰 안내레일(3)의 안내를 받으면 유동홀도(8)가 슬라이딩 되게 하는 한편 분도기(2)의 중간 위치에 투공된 체결공(1)에는 선택적으로 고정핀(10)을 삽입할 수 있도록 구성된 것으로서 미설명 부호 11은 필기구인 것이다.At one end, a protractor (2) having a fastening hole (1) is formed, and the guide rail (3) protrudes upwards and the assembly hole (4) on the guide rail (3) of the bar (5) through which the long hole (4) is perforated. And the guide groove 9 of the flow holder 8 to which the fastening bolts 7 and 7 'are fastened to receive the guide rail 3 so that the flow hole 8 slides while the protractor 2 The fastening hole (1) perforated in the intermediate position of) is configured to selectively insert the fixing pin 10, reference numeral 11 is a writing instrument.

이와 같이 구성되어진 본 고안의 작용효과를 상세히 설명하면 다음과 같다.If described in detail the effect of the present invention is configured as follows.

막대자로서의 사용하고자 할 때는 막대자(5)에 인쇄된 눈금을 통해 일반적인 막대자로서 사용할 수 있고 또한, 분도기로서 사용하고자 할 때에는 막대자(5)의 일단부에 형성된 분도기(2)를 통해 위치변경해가면서 360°모든 분할각 범위를 자유롭게 사용할 수 있을 뿐아니라, 콤퍼스로서 사용하고자 할 때에는 분도기(2)의 중앙위치에 투공된 체결공(1)에 고정핀(10)을 삽입고정하고 도시하고자 하는 원의 중심점에 고정핀(10)을 정지위치 시키면서 도시하고자 하는 원의 중심점에 고정핀(10)을 정지위치 시키면서 도시하고자 하는 원의 반지름의 정도에 맞게 유동홀더(8)의 위치를 조임볼트(7)를 풀어 안내레일(3)로부터 해제시켜 이동시킨 후 조임볼트(7)를 조여 유동홀더(8)의 위치고정시키면서 조립공(4)에는 필기구(11)를 삽입하게되면 막대자(5) 에 장방향으로 투공형성된 장홀(4)과 일치되어 삽입된 필기구(11)의 심체가 도면 제2도에 도시된 바와 같이 지면에 맞닿는 위치로 필기구(11)의 삽입정도를 세팅한 후 조임볼트(7')을 조여 필기구(11)의 유동을 정지시킨 상태에서 고정핀(10)을 중심점으로 막대자(5)를 회전이동시킴으로서 원하는 원을 도시할 수 있게 된것이다.When using as a bar, it can be used as a general bar through the scale printed on the bar (5), and when using as a protractor, it is positioned through the protractor (2) formed at one end of the bar (5) In addition to being able to freely use all of the 360 ° division angle ranges while changing them, the fixing pin 10 is inserted and fixed in the fastening hole 1 perforated at the center position of the protractor 2 when it is to be used as a compass. While tightening the fixing pin 10 at the center point of the circle to stop the fixing pin 10 at the center point of the circle to be shown while tightening the position of the flow holder (8) in accordance with the degree of the radius of the circle to be shown Loosen (7) and release from guide rail (3) to move, and then tighten the tightening bolt (7) to fix the position of the flow holder (8) while inserting the writing instrument (11) in the assembly hole (4) bar (5) In the long direction Set the insertion degree of the writing instrument 11 to a position where the core of the writing instrument 11 inserted in correspondence with the perforated long hole 4 is brought into contact with the ground as shown in FIG. Tightening the pen 5 in the state of stopping the flow of the writing instrument (11) by moving the bar (5) to the center point will be able to show the desired circle.

즉, 사용자의 사용처에 따라 분도기 혹은 막대자 그리고 콤퍼스로서 그 기능을 발휘할 수 있게 되므로서 하나의 일체형 교구를 가지고 다기능을 겸할 수 있게 한 것이다.In other words, it can be used as a protractor or bar and a compass according to the user's use, so that it can be multifunctional with an integrated teaching aid.
