이 고안은 샤프펜슬에 관한 것으로서, 특히 조출관을 지면에 대고 펜슬튜브를 가압함에 의해 연필심을 조출할 수 있게 되어 있는 샤프펜슬에 관한 것이다.The present invention relates to a mechanical pencil, and more particularly, to a mechanical pencil that can draw a pencil lead by pressing a pencil tube against the ground and pressing a pencil tube.

종래의 샤프펜슬을 펜슬튜브의 선단에 조출관이 구성되고 상단에는 프시버튼이 구성된 것으로서, 연필심을 조출하고자 할 때에는 상단의 푸쉬버튼을 눌러주면 되는 것이었으며, 연필심의 조출동작을 보면 푸쉬버튼의 가압시 내부의 연필심 튜브가 하강하면서 튜브선단의 콜릿이 풀려 연필심을 조출시키게 되는 것이며, 푸쉬버튼의 가압을 풀면 리턴스프링에 의하여 연필심 튜브가 상승하면서 콜릿이 잠겨 조출상태의 연필심을 고정할 수 있게 되어 있는 것이었다.Conventional mechanical pencil is composed of a dispensing tube at the tip of the pencil tube and a push button at the top, when pressing the push button at the top of the pencil lead to draw the pencil, press the push button of the pencil lead When the pencil core tube inside the city is lowered, the collet at the tip of the tube is released and the pencil core is released. Was.

이와 같은 샤프펜슬을 필기중 연필심이 부러진 경우 상기와 같은 연필심 조출동작을 취해야 하기 때문에 필기 자세가 산만해지는 것이었고, 또한 그 조작도 번거로운 것이었다.When the pencil lead is broken while writing such a pencil, the pencil lead dispensing operation should be performed as described above, and the writing posture is distracted, and the manipulation thereof is also cumbersome.

이 고안은 상기와 같은 결점을 개선하는 샤프펜슬에 관한 것으로서 필기중 연필을 잡은 자세를 유지한 상태에서 조출관을 지면에 대고 눌러주는 동작에 의하여 연필심을 조출할 수 있게 되어 있는 샤프펜슬을 제공함에 목적이 있으며, 이를 위하여 이 고안은 펜슬튜브의 선단에 반전판스프링을 가지는 진퇴 조출관을 구성하고 있으며, 연필심튜브 선단의 콜릿은 상기 조출관에 장착시킨 반전스프링에 의하여 잠기고 풀리는 동작이 유지될 수 있게 구성함을 특징으로 하는 것이다.The present invention relates to a mechanical pencil that improves the above-described drawbacks, and provides a mechanical pencil capable of dispensing a pencil lead by pressing the tapping tube against the ground while maintaining a pencil holding position during writing. To this end, this design constitutes a retreat feeding tube having a reverse plate spring at the tip of the pencil tube, and the collet of the tip of the pencil core tube can be kept locked and released by the reversing spring mounted at the discharge tube. It is characterized by the configuration.

이 고안은 첨부도면에 따라 상세하게 설명하면 다음과 같다.This invention is described in detail according to the accompanying drawings as follows.

펜슬튜브(1)내에 콜릿(8)을 가지는 연필심튜브(2)를 내장시켜서 된 것에 있어서, 펜슬튜브(1)의 선단에 연필심을 조출관(3)을 삽입하고, 조출관(3) 주벽의 안내공(4)에 펜슬 튜브(1)측의 걸턱(5)을 끼워 상기 조출관(3)이 일정한 거리를 진퇴작동할 수 있게 구성하였으며, 펜슬튜브(1)측의 내면홈(6)에 원추형 반전판(7)을 장착시켜 그 선단부가 상부로 이동가능한 연필심튜브(2) 선단의 콜릿(8)과 밀턱(9)사이에 위치하게 하였고, 또한 상기 조출관(3)측의 상하 반전아암(10)(10')사이에 상기 반전판(7)이 대응되게 구성하였으며, 상기 연필심튜브(2)가 펜슬튜브(1) 내벽의 스토퍼 (11)에 걸리고, 상기 연필심 조출관(3)의 내단에 리턴스프링(12)을 탄성시켜서 된 것이다.The pencil core tube 2 having the collet 8 is incorporated in the pencil tube 1, and the dispensing tube 3 is inserted into the dispensing tube 3 at the tip of the pencil tube 1, The guide tube 4 is fitted with a jaw 5 on the side of the pencil tube 1 so that the feeding tube 3 can move forward and backward a predetermined distance, and the inner groove 6 on the side of the pencil tube 1. The conical inverting plate (7) was mounted so that its tip was positioned between the collet (8) and the tip (9) of the tip of the pencil core tube (2), which was movable upwards, and the upper and lower inverting arms on the side of the feeding tube (3). The reverse plate (7) is configured to correspond between the (10) (10 '), the pencil core tube (2) is caught by the stopper (11) of the inner wall of the pencil tube (1), of the pencil lead tube (3) It is made by elasticizing the return spring 12 at the inner end.

제1도의 필기상태도를 설명하면 다음과 같다.The writing state diagram of FIG. 1 is as follows.

연필심튜브(2)는 스토퍼(11)에 걸려 있고 그 선단의 콜릿(8)은 저부로 융기된 반전판(7)의 선단에 밀림으로써 잠겨 있게 되어 결국 연필심 튜브(2)는 펜슬튜브(1)측에 고정된 상태가 되는 것이고, 또한 연필심(13)은 상기 연필심 튜브(2)상에서 콜릿(8)에 의해 고정되어 있어 사용자는 펜슬 튜브(1)을 잡은 상태에서 필기를 행할 수가 있게 되는 것이다.The pencil core tube 2 is hung on the stopper 11 and the collet 8 at the tip thereof is locked by being pushed at the tip of the inverted plate 7 which is raised to the bottom so that the pencil core tube 2 is the pencil tube 1. The pencil core 13 is fixed to the side by the collet 8 on the pencil core tube 2 so that the user can write while holding the pencil tube 1.

상기의 필기 상태에서 연필심(13)이 닳아 짧아지거나 부러졌을 경우 조출관(3)을 지면에 대고 펜슬튜브(1)를 눌렀다가 놓으면 연필심은 제1도의 필기 상태로 조출되는 것이다.When the pencil lead 13 is shortened or broken in the writing state, the pencil lead is fed to the writing state of FIG. 1 by pressing and releasing the pencil tube 1 against the ground.

이러한 연필심의 조출동작을 제2도에 따라서 설명하면 다음과 같다.Referring to the drawing operation of the pencil lead according to Figure 2 as follows.

즉, 상기와 같이 펜슬튜브(1)을 가압하게 되면 조출관(3)이 스프링(12)을 압축하면서 펜슬튜브(1)속으로 밀려 들어가게 되는데 이동작에서 저부의 반전아암(10')이 반전판(7)의 내연부를 밀어올리게 되는 것이며, 상기와 같은 동작을 할 때 반전판(7)의 내연부가 펜슬튜브(1)의 내면홈(6)의 위치를 통과하면서 반전판(7)은 연필심 튜브(2)의 밀턱(9)을 밀어 올리게 되므로 콜릿(8)의 잠금상태가 풀려 연필심(13)은 조출상태가 되는 것이다.That is, when the pencil tube 1 is pressed as described above, the feeding tube 3 is pushed into the pencil tube 1 while compressing the spring 12, and the inverting arm 10 'at the bottom is reversed in the movement. The inner edge of the plate 7 is pushed up, and when the above operation is performed, the inner edge of the inverting plate 7 passes through the position of the inner groove 6 of the pencil tube 1, and the inverting plate 7 is a pencil core. Since the pushed up the jaw 9 of the tube 2, the locking state of the collet 8 is released, and the pencil lead 13 is brought out.

이때 콜릿(8)은 연필심(13)의 후방위치로 이동되는 것이고, 이 상태에서 펜슬튜브(1)에 가하면 압력을 제거하게 되면 리턴 스프링(12)이 연필심조출관(3)을 밀어내리게 되는 것이며, 이동작에서 상부의 반전아암(10)은 반전판(7)의 내연부를 밀어내려 제1도와 같은 상태로 환원시키게 되는 것이고, 이 결과 조출관(3)은 걸턱(5)에 닿아 하강동작이 정지되면서 콜릿(8)을 동작전의 잠금 상태로 되어 다시 필기상태가 되는 것이다.At this time, the collet 8 is moved to the rear position of the pencil lead 13, and when the pressure is removed from the pencil tube 1 in this state, the return spring 12 will push the pencil lead tube 3 down. In the movable operation, the upper inversion arm 10 pushes the inner edge of the inversion plate 7 to reduce it to the state as shown in FIG. 1, and as a result, the feeding tube 3 touches the sledge 5 so that the lowering operation While stopping, the collet 8 is locked before the operation and becomes a writing state again.

상기와 같이 이 고안은 필기자세를 그대로 유지하면서 연필심을 조출할 수 있는 샤프펜슬을 제공하게 된 것으로 종래의 샤프펜슬에 비하여 연필심의 조출조작이 더욱 편리해진 실용적인 고안이다.As described above, the present invention is to provide a mechanical pencil that can extract the pencil lead while maintaining the writing position as it is, a practical design that makes the operation of the pencil lead more convenient than the conventional pencil.
