본 고안은 종래의 샤프펜 구조에 있어서 내부구성부인 심통과 벌개형 척 구조를 칼날심을 지지하고 일정길이만큼 도출시키는데 특히 적합한 구조로 하여 두께가 얇고 폭이 좁은 칼날심을 연필심 대용으로 사용할 수 있도록 함으로서 도형이나 무늬 등을 정밀하게 오려내는 용도로 이용하도록 한 샤프펜에 관한 것이다.The present invention is a structure that is particularly suitable for supporting the blade core and deriving a certain length of the core barrel and the opening-type chuck structure of the conventional mechanical pencil structure, so that a thin blade and a narrow blade core can be used as a substitute for the pencil core. The present invention relates to a mechanical pencil for use in accurately cutting out a pattern or a pattern.
종래 각종 그림을 오리는 용도로 오림용 칼을 사용하고 있는바, 종래의 오림용 칼은 끝이 뾰족한 칼을 사용하기 쉽도록 대에 꽂아 사용하거나 커터칼을 오림용칼 대용으로 사용하여 옴으로서 오림작업이 능률이 떨어지고 정밀오림작업이 곤란하며, 칼날이 무디어 졌을 경우 교체하기가 곤란한 문제점이 있었다. 본 고안은 손에 쉽게 익숙하고 심의 교체도 용이한 샤프펜을 킬날심을 사용할 수 있도록 개량함으로서 오림작업에 적합하게 하고 사용도 간편하게 할 목적으로 안출된 것이다.Conventionally, the cutting knife is used for cutting various kinds of pictures. The cutting knife for the conventional cutting machine is used by inserting a knife with a sharp tip for easy use, or by using a cutter knife as a substitute for cutting knife. This efficiency is difficult and precision rounding is difficult, and when the blade is blunt, there was a problem that it is difficult to replace. The present invention is designed to fit the cutting work and to simplify the use by improving the sharp pen to be used in the hand and easy to replace the shim to use the kill blade.
이와 같은 목적을 달성하기 위한 본 고안의 구성 및 효과를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.The construction and effects of the present invention for achieving the above object will be described in detail with reference to the accompanying drawings.
제1도는 본 고안을 적용한 샤프펜슬의 구성을 보인 것이며, 제2도 및 제3도는 벌개형 척을, 제4도 및 제5도는 본 고안에 사용되는 칼날심을, 제6도는 본 고안의 전체 결합상태도를 도시한 것이다.Figure 1 shows the configuration of the mechanical pencil according to the present invention, Figures 2 and 3 is a cut-off chuck, Figures 4 and 5 are the blades used in the present invention, Figure 6 is a combination of the present invention The state diagram is shown.
제1도에서 보는 바와 같이 본 고안이 적용된 샤프펜슬은 심통(3)의 하부단에 스프링(4), 고정용링(5), 슬리브(6) 및 벌개형척(7)이 일련체로 각 구성부분 상호간 활설되거나 고정되어 내부구성체를 이루고, 이것이 펜대(1)에 삽입되고 출구캡(2)에 의해 고정되어 펜대상부에 노출되는 심통단부를 눌렀을때 변위되는 길이만큼 척에 물려진 심을 출구캡(2)외부로 도출되도록 된 구조를 갖는 것임을 보여준다.As shown in FIG. 1, the mechanical pencil to which the present invention is applied includes a spring 4, a fixing ring 5, a sleeve 6, and a bevel chuck 7 at a lower end of the core barrel 3 in a series. The shim bitten by the chuck as long as it is displaced when the end of the core is inserted into the pen holder 1 and fixed by the outlet cap 2 and exposed by the pen cap 1 to the pen target portion. It shows that it has a structure that is intended to be drawn outward.
상기 구성에 있어서, 심통 내부의 관통홉(3a)을 장방형으로 하고, 여기에 결합되는 벌개형 척(7) 내부의 관통홈(7a)을 심통의 관통홈과 단면형태와 크기가 같은 장방형으로 하여 각각의 홈이 일치되도록 결합하며, 벌개형 척에 형성되는 슬릿(7c)은 관통홈의 각변 중앙부에 위치하도록 4개를 형성한 구성으로 하며, 심은 일정 간격으로 절취홈(9a)이 형성된 판형의 칼날심(9)을 사용할 수 있도록 한 것이다.In the above configuration, the through-hop 3a in the core barrel is made into a rectangle, and the through-hole 7a in the bevel-shaped chuck 7 coupled thereto is made into a rectangle having the same cross-sectional shape and size as the through-hole in the core. Each groove is coupled to match, the slits (7c) formed in the open-type chuck is formed of four formed so as to be located at the center of each side of the through groove, the core is formed of a plate-shaped cut groove (9a) at regular intervals The blade (9) is to be used.
이상과 같은 구성에 의하여 심통에 삽입된 칼날심은 심통과 벌개형 척의 내부 관통홈을 따라 자연스럽게 이동할 수 있게 되며 스프링에 복원력이 작용할때는 슬리브(6)가 벌개형 척의 테이퍼 단(7a)에 밀착되어 척단부를 오무려줌으로 칼탈심이 척에 고정되고, 심통의 캡을 눌러주면 스프링이 압축되면서 슬리브와 척의 결합상태가 해제되고, 심통과 여기에 고정되는 벌개형 척 및 칼날심을 누름변위만큼 전진시킨다.The blade core inserted into the core can be moved naturally along the internal through groove of the core and the open-type chuck. When the restoring force is applied to the spring, the sleeve 6 is in close contact with the tapered end 7a of the open-type chuck. By pinching the end, the knife core is fixed to the chuck, and pressing the cap of the core pain, the spring is compressed to release the coupling state of the sleeve and the chuck, advances the core and the blade-type chuck and blade core fixed to it as much as the pressing displacement.
심통캡의 누름 상태를 해제하면, 스프링의 복원력이 작용하여 칼날심은 그대로 둔 상태에서 심통과 여기에 고정된 벌개형 척만 후퇴하여 슬리브와 다시 밀착되어 칼날심을 고정한다.When the release state of the core cap is released, the restoring force of the spring acts and the blade core remains intact, and only the core tube and the stick-type chuck fixed thereto are retracted to closely contact with the sleeve to fix the blade core.
이상과 같은 동작을 반복함으로써 칼날심을 누름 변위만큼 계속적으로 도출시키게 된다.By repeating the above operation, the blade edge is continuously drawn as much as the pressing displacement.
심통내부의 장방형 관통홈(3a)은 칼날심의 심통내부에서 방향전환되는 것을 방지하여 방향전환 없이 벌개형척에 유입되도록 하기 위한 것이며 벌개형 척 내부의 장방형 관통홈은 칼날심과의 밀착효과를 높여 칼날심이 척에 고정된 후에는 다소 무리한 힘을 가하더라도 밀려나는 일이 없도록 하기 위한 것이고, 슬릿을 4개로 한것은 칼날심의 양면에 접촉압을 균등하게 하며 척이 탄력성을 잃지 않고 용이하게 복원되도록 하기 위한 것이다.The rectangular through groove (3a) in the inner barrel is to prevent the change of direction in the inner core of the blade core so as to be introduced into the opening chuck without the change of direction, and the rectangular through groove inside the opening chuck improves the effect of close contact with the blade core. After the shim is fixed to the chuck, it is to prevent it from being pushed out even if you apply some excessive force, and 4 slits are used to equalize the contact pressure on both sides of the blade core and to allow the chuck to be easily restored without losing elasticity. will be.
또한 칼날심에 형성된 절취홈은 사용후 무디어진 칼날을 용이하게 제거하여 항상 날이선 칼날로 오림작업을 할 수 있도록 한 것이다.In addition, the cutting groove formed on the blade core is easy to remove the blunt blade after use so that the cutting work always with a cutting edge blade.
이상에서 설명한 바와같이 본 고안은 종래의 샤프펜슬의 구성부분중 일부를 개량하여 칼날심을 연필심 대용으로 사용할 수 있도록 함으로써 평소 필기에 익숙한 손놀림으로 복잡한 도형이나 무늬 등을 정밀하게 오려낼 수 있고 휴대와 사용이 매우 간편한 효과를 발휘한다.As described above, the present invention improves some of the components of the conventional mechanical pencil so that the blade core can be used as a substitute for the pencil core, so that complicated shapes and patterns can be precisely cut out by hand-handling that is familiar with usual writing, and can be used with the portable This is a very easy effect.
