본 고안은 조깁식 흑판지우개에 관한 것이다.The present invention relates to an Gibbon type black eraser.
종래의 것은 흑판지우개에 있어서 지우개부의 포(布)부분이 마모되며는 흑판지우개 전체를 버려야 하는 결점이 있다.The related art has a drawback in that the cloth portion of the eraser is worn out in the black eraser and the entire black eraser must be discarded.
본 고안은 이와 같은 결점을 해결코져 안출한 것으로서 이를 도면에 따라 상술하면 다음과 같다.The present invention has been made to solve such drawbacks as described in detail according to the drawings as follows.
솜을 포(布)로 싸서 지우개부(1)를 원통형으로 형성하고 이를 플라스틱으로 된 지우개부 고정편(2)에 끼워 넣은 다음, 지우개부(1)를 지우개부 고정편(2)에 끼워 넣은 것을 플라스틱의 지우개 손잡이(3)의 지우개부 고정편턱(4)까지 끼워 넣어서 조립식 흑판지우개(6)를 완성한다.The cotton was wrapped with a cloth to form the eraser portion 1 into a cylindrical shape and inserted into the eraser fixing piece 2 made of plastic, and then the eraser portion 1 was inserted into the eraser fixing piece 2 To the eraser fixing fixing jaw (4) of the plastic eraser handle (3) to complete the prefabricated blackboard eraser (6).
이와 같이 완성된 조립식 흑판지우개를 사용하여 지우개부(1)가 마모되며는 조립식 흑판지우개(5)를 분해한 다음 지우개부(1)의 마모되지 않은 부위로 돌려 끼우고 다시 조립식 흑판지우개(6)를 조립한 다음 반복 사용한다.When the eraser portion 1 is worn out using the prefabricated black eraser thus completed, the prefabricated black eraser 5 is disassembled and then screwed back into the unworn portion of the eraser 1 and then assembled black eraser 6 again. Assemble and use repeatedly.
이와 같이 지우개부(1)가 마모되며는 마모되지 않은 부위로 돌려 끼워서 사용한다. 그리고 조립식 흑판지우개(6)를 사용할 때에는 손잡이부(5)를 잡고 사용한다.In this way, the eraser 1 is worn and then used by inserting it into a portion that is not worn. And when using the prefabricated blackboard eraser (6) is used to hold the handle (5).
위와 같이 흑판지우개를 조립식으로 하여 사용하므로서 첫째, 지우개부(1)만을 교체하며는 영구히 사용할 수 있고, 둘째, 지우개부(1)도 돌려 끼워 넣으므로서 지우개부(1)의 원통형의 전면을 사용할 수 있어 장기간 사용할 수 있는 등의 우수한 효과가 있다.By using the black eraser as a prefabrication as described above, first, only the eraser portion (1) can be replaced permanently, and secondly, by inserting the eraser portion (1) by turning the cylindrical front of the eraser portion (1) It is excellent in that it can be used for a long time.
