본 고안은 지우개 심체를 각형관체로 형성하여 그 상면부와 하면부의 외면에 길이방향으로 나란하게 요입홈과 돌조를 다수조 형성하여 그 외면에 역시 요입홈과 돌재가 형성된 지우개포를 피복하고 상면은 착탈가능한 덮개를 덮어 사용하므로써 상하 양면을 번갈아 사용할 수 있게한 것인데, 본 고안의 목적은 지우개의 작용이 정확하고 수명이 오래 가는 실용적인 제품을 염가로 얻고저 한 것이다.The present invention forms an eraser core with a square tube and forms a plurality of grooves and protrusions in the longitudinal direction side by side on the outer surface of the upper and lower surfaces thereof, covering the eraser with the recess groove and the stone formed on the outer surface. By using a removable cover to cover the upper and lower sides can be used alternately, the purpose of the present invention is to obtain a practical product that the operation of the eraser is accurate and long life at low cost.
종래의 흑판지우개는 손잡이의 저면에 융출부를 형성하여 그 내부에 심재를 넣고 표면에 비로드지 등과같은 지우개포를 피복하였기 때문에 편면밖에 사용할수 없었고 탄력성이 빨리 줄어들어 통기성이 적어지므로 지우개가 잘 닦이지 않는 결점이 있을뿐 아니라 직포의 흡인력이 적어서 분필가루가 많이 날리는 등의 결점이 있었던 것이다.Conventional black eraser has a flaw on the bottom of the handle, puts a core material inside, and covers the eraser cloth such as non-loaded paper on the surface, so it can only be used on one side and the elasticity decreases quickly, resulting in less breathability. In addition to this, there is a drawback of the fact that the woven fabric has a low suction force, so much chalk powder is blown.
본 고안은 위와같은 종래의 결점을 시정하기 위하여 안출한 것으로 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention has been devised to correct the above-described drawbacks and will be described in detail with reference to the accompanying drawings.
4각형 관체로된 지우개 심체(1)의 상하면부(2), (3)에 각각 표면으로 다수조의 돌조(2'), (3')와 요입홈(2"), (3")을 번갈아 형성시켜 그 외면에 피복되는 지우개포(5)에는 표면을 따라 심체의 돌조방향과 나란하게 기모섬유돌재(4)와 요입홈(4')이 형성되게 하여 양측면에서 심체(1)속으로 마개(7)의 삽입부(6)를 삽입한 다음 상면부 외면에 덮개(9)를 피복하여 주벽(9') 내면의 돌기(10)가 마개의 결합공(8)에 감합되게한 구조이다.On the upper and lower portions 2 and 3 of the eraser core 1 made of a square tubular body, a plurality of sets of protrusions 2 ', 3' and recessed grooves 2 'and 3' are alternately disposed on the surface. Formed and covered on the outer surface of the eraser cloth (5) is formed along the surface along the surface of the core fiber stone 4 and the recessed groove (4 ') to form a stopper into the core (1) on both sides ( The insertion part 6 of 7) is inserted, and then the cover 9 is coated on the outer surface of the upper surface part so that the protrusion 10 on the inner surface of the main wall 9 'is fitted into the coupling hole 8 of the plug.
이와같이된 본 고안은 흑판지우개포(5)의 표면에 다수조의 기모 섬유에 의한 돌재(4)와 요입홈(4')이 나란히 형성되어서 심체(1)의 표면에 형성된 돌조(2'), (3')와 요입홈(2"), (3")에 밀착되어 피복되기 때문에 지우개를 사용할때 직포에 가해지는 압력과 바람이 직포를 통해 심체의 요입홈(3"), (3")로 순환되어 흡인력이 커지게 되므로 가루가 직포에서 날리지 않고 지우개가 잘 닦이는 이점이 있도록 되고 직포가 심체표면에 접착되지 않으면서 지우개 작용을 할수가 있는 이점이 있으며 상변부 덮개(9)를 벗겨서 하면부에 착설하면 상면부가 노출되게 되어서 새것처럼 사용할수 있도록 되기 때문에 양면 모두를 지우개로 사용할 수 있어서 종래보다 수명이 긴 장점이 있으며 분해가 용이하여 직포의 교환이 쉽기 때문에 매우 편리한 이점도 있는 효과가 있다.In this way, the present invention is a stone (2 ') formed on the surface of the core (1) by forming a stone 4 and the recessed groove (4') by a plurality of sets of brushed fibers on the surface of the black cardboard canine (5), ( 3 ') and the indentation grooves (2 ") and (3") are tightly coated so that the pressure and wind applied to the fabric when using an eraser are transferred to the indentation grooves (3 ") and (3") of the core through the fabric. Circulation increases the suction force, so that the powder does not fly out of the woven fabric, and the eraser is well wiped, and the woven fabric has the advantage of working as an eraser without being adhered to the core surface. When installed, the upper surface is exposed so that it can be used as a new one, so both sides can be used as an eraser, which has the advantage of longer life than the conventional one, and it is easy to disassemble, so it is easy to replace the woven fabric.
