본 고안은 샤프펜슬의 녹크(KNOCK) 장치에 관한 것으로, 특히 필심튜우브에 녹크를 끼울때 접촉면적을 넓혀 견고하게 끼워져 고무캡을 벗길때 녹크가 불필요하게 빠지는 것을 방지하며, 필관의 굵기에 구애없이 사용할 수 있도록 고안된 것이다.The present invention relates to a KNOCK device of a mechanical pencil, and particularly, when the nut is inserted into the fill tube, the contact area is secured by expanding the contact area to prevent unnecessary knocking out of the rubber cap when removing the rubber cap. It is designed to be used without it.
종래의 샤프펜슬에는 필심튜우브 후단에 녹크를 끼우되, 그 전체가 필관내부에 끼워지도록 된 것(대한민국 실용신안 공고번호 제84-1765호)이 있었으나, 필심 튜우브와 녹크의 결합은 녹크 내면에 돌출된 다수개의 돌기부분과 접촉된 것이어서 사용빈도가 많아지면서 마모되면 고무캡을 벗길때 불필요하게 빠져나와 사용에 불편이 있었고, 녹크에 형성된 고무캡받침턱 부분이 필관 내부에 끼워지는 것이어서 필관은 이에따라 불필요하게 굵어져야만 하는 제작상의 문제점이 있었다.In the conventional mechanical pencil, there was one in which a knock was inserted at the rear end of the pen tube, and the whole was inserted in the pen tube (Korean Utility Model Publication No. 84-1765), but the combination of the pen tube and the knock was made on the inner surface of the knock. It was in contact with a number of protruding protrusions, which increased the frequency of use, and when worn out, the rubber cap was removed unnecessarily when removing the rubber cap. There was a manufacturing problem that had to be unnecessarily thick.
본 고안에서는 이상과 같은 종래의 문제점을 해결하기 위하여 필심튜우브에 끼워지는 녹크의 일부인 삽입관체내부에 탄성을 주어 내면에 형성된 두부에 접촉 탄압되어 견고하게 끼워지도록 하고, 고무캡받침턱 부분은 필관 외부로 노출시켜 필관의 굵기에 구애없이 제작하도록한 것이다.In the present invention, in order to solve the conventional problems as described above, it is elastically inserted into the insertion tube body, which is a part of the knock inserted into the fill tube, so as to be firmly fitted by contact with the head formed on the inner surface, and the rubber cap support jaw portion By exposing to the outside, regardless of the thickness of the pen.
이를 첨부된 도면에 의하여 그 구성을 상세히 설명하면 다음과 같다.This configuration will be described in detail with reference to the accompanying drawings.
필심튜우브(1)에 고무(2)가 상단에 끼워지는 녹크(3)를 끼워서 되는 샤프펜슬의 녹크장치에 있어서, 녹크(3)의 하부에 필심튜우브삽입관체(4)를 길게 형성하되, 그 외주벽에 길이 방향으로 한개 또는 다수개의 종절개홈(5)을 형성하며, 내면에는 두부(6)를 돌출시켜 내경은 필심튜우브(1) 외경보다 약간 작게 형성하여 착용시 빡빡하게 끼워지도록 하며, 필심튜우브삽입관체(4) 상부에는 녹크(3)의 작동거리(X)를 두고 그 위에 고무캡 받침턱(6)을 형성한 구조이다.In the mechanical pencil knocking device in which the knock tube 3 into which the rubber 2 is fitted at the upper end thereof is inserted into the fill tube 2, the fill tube 2 is formed long in the lower portion of the knock tube 3; One or a plurality of longitudinal incision grooves 5 are formed in the outer circumference of the outer wall, and the head 6 is protruded on the inner surface so that the inner diameter is slightly smaller than the outer diameter of the pen core tube 1 so that it may be tightly fitted. The top of the fill tube insertion tube (4) has a working distance (X) of the knock (3) and the rubber cap support jaw (6) is formed thereon.
도면중 미설명 부호 8은 고무캡, 9는 필관, 10은 소재핀의 예시이다.In the drawings, reference numeral 8 is an example of a rubber cap, 9 is a tube, and 10 is an example of a material pin.
본 고안 실시에 있어서 필심튜우브삽입관(4)의 입구(11) 부분은 크고 상단에 안내경사면(12)을 형성하여 필심튜우브(1)를 끼우기 편리하도록 구성한다.In the implementation of the present invention, the inlet portion 11 of the fill tube insertion tube 4 is large and is formed so as to conveniently fit the fill tube (1) by forming a guide inclined surface 12 on the top.
이상과 같은 본 고안 녹크장치는 필심튜우브(1)의 상부가 필심튜우브삽입관체(4) 내면에 돌출된 두부(6)에 빡빡하게 끼워지면서 종절개홈(5)으로 신축성이 부여된 탄성으로 견고하게 끼워져 있어, 종래의 돌기만으로 접촉된 것에 비해 매우 견고하므로 고무캡(8)을 벗길때 녹크(3)가 빠지는 것이 방지되며, 고무캡받침턱(7)은 필관(9)의 상단에서 녹크작동거리(x)를 두고 그위에 형성한 것이어서 종래에 필관(9) 내부에 받침턱(7)이 끼워져 있는 경우와는 달리 제작시 필관(9)의 굵기에 따라 구애가 없으므로 불필요하게 필관(9)이 받침턱(7)이 튀어나온 만큼 굵어지는 문제점도 방지하여 임의로 제작할 수 있는 효과가 있다.The knock device according to the present invention is elastically provided with elasticity as the longitudinal incision groove 5 while the upper part of the fill tube (1) is tightly fitted into the head (6) protruding from the inner surface of the fill tube (4). Since it is firmly fitted, it is very hard compared with the conventional protrusions only, so that the knock (3) is prevented from coming off when the rubber cap (8) is removed, and the rubber cap support jaw (7) is at the top of the tube (9). It is formed on the knock operation distance (x), and unlike the case where the base jaw (7) is fitted in the inside of the pipe tube (9) in the past, there is no need to adhere to the thickness of the pipe tube (9) during manufacturing, so 9) it is also effective to prevent the problem of thickening as the support jaw (7) protrudes can be produced arbitrarily.
