본 고안은 예컨대 샤아프펜슬등과 같은 필기구의 외통과 선단캡의 결합구조를 개량시킨 필기구에 관한 것이다. 종래의 샤아프펜슬과 같은 필기구에 있어 필심이 관통되어 내보내지는 선단캡이 착탈시켜질 수 있도록 된 구조를 갖는 것은, 필심파이프가 축방향으로 미끄럼왕복이동할 수 있도록 끼워넣어지는 외통앞끝에 작은 직경계단형상의 이음원통부를 동축선상에 일체로 형성시키고, 이 이음원통부의 외주면에다 한쪽방향 숫나사부를 형성시키는 한편, 선단캡내주면에는 나사결합시켜 외통앞끝에다 선단캡을 결합시키고 있었다.The present invention relates to a writing instrument that improves the coupling structure of the outer cap of the writing instrument such as a mechanical pencil and the like and the tip cap. In a writing instrument such as a conventional pencil pencil, the tip cap which penetrates the pen core can be detached, and has a small diameter staircase at the front end of the outer tube inserted so that the pen core pipe can slide in the axial direction. The jointed cylindrical portion was formed integrally on the coaxial line, and the male threaded portion was formed on the outer circumferential surface of the jointed cylindrical portion, while the end cap was screwed to the inner circumferential surface of the distal end cap to engage the distal end cap.

그러나 이와 같은 종래의 샤아프펜슬에서는 선단캡을 돌려 외통의 이음원통부에 나사결합으로 끼워주어야만 외통에 선단캡을 결합시킬 수가 있기 때문에 선단캡을 결합시키는데 손이 많이 들기 때문에 특히 샤아프펜슬의 생산성이 나빠지게 된다고 하는 문제점과, 상기 이음원통부에 나사결합되어 끼워진 선단캡이 빠지기가 쉬워 샤아프펜슬을 휴대할 때 상기 선단캡을 분실하게 되는 일이 많다고 하는 것이 문제로 되고 있다.However, in the conventional mechanical pencil, it is necessary to turn the tip cap and screw it into the joint portion of the outer cylinder so that the end cap can be coupled to the outer cylinder. The problem of this deterioration, and the tip cap screwed into the joint cylinder portion is easy to come off, and the tip cap is often lost when carrying the mechanical pencil.

이에 본 고안은 상기와 같은 문제점들을 해결하기 위해 고안되 것으로, 외통의 앞끝내부에 선단캡을 밀어 끼워주기만 하는 원터치조작으로 선단캡을 간단하고 확실하게 결합시켜줄 수 있고 결합된 다음 선단캡이 멋대로 빠져나갈 염려가 없는 필기구를 제공함에 그 목적이 있다.The present invention is designed to solve the above problems, the one-touch operation that only pushes the tip cap into the front end of the outer cylinder can be simply and securely combined the tip cap and then the tip cap is freely combined The purpose is to provide writing instruments that do not worry about going out.

상기와 같은 목적을 달성하기 위한 본 고안 필기구는, 필심파이프가 축방향으로 미끄럼왕복이용할 수 있도록 끼워넣어지는 외통의 앞끝쪽 내주면에 소정방향 또는 소정형상으로 된 암나사부가 형성됨과 더불어, 선단캡 뒷끝부위에 축방향으로 일체적으로 형성된 작은 직경계단형상으로 된 이음원통부의 외주면에 상기 암나사부에 잇빨물림되는 한쪽방향숫나사부가 형성되어, 외통의 앞끝쪽내부에다 선단캡의 이음원통부를 눌러끼워 그들 나사부들이 상호 잇빨물림되도록 된 구성으로 되어 있다.In order to achieve the above object, the present invention writing instrument has a female screw part formed in a predetermined direction or a predetermined shape on the inner circumferential surface of the front end of the outer tube into which the lead pipe can be slidably used in the axial direction, and the rear end portion of the tip cap. On the outer circumferential surface of the small cylindrical stepped cylindrical portion integrally formed in the axial direction, a male threaded portion is formed in the female threaded portion, and the threaded portion of the end cap is pressed into the front end of the outer cylinder. It is designed to interlock each other.

이와 같이 구성된 본 고안에 있어서는, 외통의 앞끝쪽내부에 선단캡의 이음원통부를 눌러밀어 넣게 되면 이 이음원통부외주면에 형성된 한쪽방향숫나사부가 외통내주면의 양방향 암나사부에 잇빨물림되어 특히 필기구를 휴대하는 경우와 같이 평상시 선단캡을 빼내는 방향으로의 회전에 대해서는 외통의 이음원통부에서 상기 선단캡의 숫나사부와 반대방향으로 되는 다른 방향암나사부가 선단캡의 빠짐을 방지하는 스토퍼로서 작동하게 됨으로써, 외통앞끝에 선단캡이 확실하고 견고한 상태로 결합시켜져 있게 된다.In the present invention configured as described above, when the joint portion of the tip cap is pushed into the inner end of the outer cylinder, the male thread portion formed on the outer circumferential surface of the joint cylinder is entangled in the bidirectional female screw portion of the outer cylinder inner surface to carry the writing instrument. As for the rotation in the direction of removing the tip cap as usual, the other direction female screw which is opposite to the male screw portion of the tip cap in the joint cylinder portion of the outer cylinder is operated as a stopper for preventing the tip cap from being pulled out. The tip cap is securely and securely coupled.

또 선단캡을 강제적으로 역회전시키게 되면 그 역회전방향을 따라 외통쪽의 한쪽방향암나사부에 선단캡의 숫나사부가 안내되어지게 됨으로서 외통으로 부터 선단캡이 빠져나오게 된다.In addition, when the tip cap is forcibly rotated, the male cap of the tip cap is guided to the female screw in one direction of the outer cylinder in the reverse rotation direction, and the tip cap comes out of the outer cylinder.

이하 본 고안의 실시예를 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도에서 도면부호 1은 샤아프펜슬의 외통으로서, 그 내부에는 도시되지 않은 필심파이프가 축방향으로 미끄럼왕복이동할 수 있도록 끼워넣어지고, 이 필심파이프의 뒷끝부위에는 녹크캡이 착탈될 수 있게 끼워지게 된다. 또 필심파이프의 앞끝쪽에도 역시 도시되지 않은 리이드척과 척링 및 상기 리이드척을 필심파이프와 함께 후퇴방향으로 밀어주는 척체결용 스프링 등으로 이루어져 녹크조작에 의해 필심을 조금씩 내보내는 필심송출기구가 배치되어 있다.In FIG. 1, reference numeral 1 denotes an outer cylinder of a mechanical pencil, in which a pen lead pipe (not shown) is slidably reciprocated in the axial direction, and a knock cap is detachable at a rear end of the pen lead pipe. Will be fitted. In addition, there is also a lead chuck mechanism, which comprises a lead chuck, a chuck ring (not shown), and a chuck fastening spring for pushing the lead chuck together with the guiding pipe in the retracting direction.

이러한 외통(1)의 앞끝쪽내부에는 제2도에 상세히 도시되어져 있는 바와 같이 한쪽방향암나사부(2)와 이와 교차하는 다른 방향암나사부(3)가 격자모양으로 형성되어져 있다.As shown in detail in FIG. 2, the one end female screw portion 2 and the other female screw portion 3 that intersect the outer cylinder 1 are formed in a lattice shape.

도면부호 4는 외통(1)의 앞끝부위에 착탈될 수 있게 장착되는 선단캡으로서, 그 축중심부에 필심안내구멍(5)을 갖고 그 뒷끝부위에 축방향으로 연장되어 나간 작은 직경계단형상을 한 이음원통부(6)가 일체로 형성되어져 있다.Reference numeral 4 is a tip cap detachably attached to the front end of the outer cylinder 1, and has a small diameter staircase shape that has a guiding hole 5 in the center of the shaft and extends in the axial direction at the rear end thereof. The joint cylinder 6 is integrally formed.

그리고 이 이음원통부(6)외주면에는 제3도에 상세히 도시되어져 있는 바와 같이 상기 한쪽방향암나사부(2)와 방향이 같고 또 피치도 같은 숫나사부(7)가 형성되어져 있다.On the outer circumferential surface of the joint cylindrical portion 6, as shown in detail in FIG. 3, a male screw portion 7 having the same direction and the same pitch as the one-way female screw portion 2 is formed.

또 선단캡(4) 내부에는 필심안내구멍(5)을 관통해서 끼워지는 필심을 척위치에서 마찰력으로 지지시켜지도록 하기 위한 필심마찰원통부재(8)가 상기 필심안내구멍(5)과 연통되는 위치에 일체로 형성되어져 있는 바, 이 필심마찰원통부재(8)에는 제4도에 도시되어져 있는 바와 같이 원주방향을 따라 일정간격을 갖고 축방향으로 슬리트(9)가 형성되어, 이 슬리트(9)에 의해 필심이 충분한 마찰력으로 걸려지도록 되어 있다.In addition, a tip friction cylindrical member (8) communicates with the lead guide hole (5) in the tip cap (4) so that the lead inserted through the lead guide hole (5) is supported by the friction force at the chuck position. As shown in FIG. 4, the slit 9 is formed in the axial direction at regular intervals along the circumferential direction, as shown in FIG. 9) The lead is to be caught with sufficient friction.

이러한 선단캡(4)은 그 이음원통부(6)를 외통(1)의 앞끝쪽내부로 끼워 눌러줌으로써 외통(1) 앞끝부위에 결합시켜지게 된다.The tip cap 4 is coupled to the front end of the outer cylinder 1 by pressing the joint cylindrical portion 6 into the front end of the outer cylinder 1.

다음에는 상기 실시에의 작용을 설명한다.Next, the operation of the above embodiment will be described.

상술한 바와 같이 외통(1)의 앞끝에 결합된 선단캡(4)은 이음원통부(6)의 숫나사부(7)가 외통(1)에 양방향으로 형성된 암나사부(2,3)에 잇빨물림된 상태로 유지시켜지게 되는바, 즉 상기 숫나사부(7)가 실제로는 그 대부분이 같은 방향의 암나사부(2)에 잇빨물림되어 지지만, 선단캡(4)의 뽑힘방향으로의 호전에 대해서는 상기 숫나사부(7)와는 반대방향으로 된 다른 방향암나사부(3)가 상기 숫나사부(7)에 스토퍼로서 작용하게 된다. 그 때문에 선단캡(4)이 뽑혀지는 방향으로 흔들려 회전하지 않게 되는 확실하고 견고한 결합상태가 유지되게 된다.As described above, the tip cap 4 coupled to the front end of the outer cylinder 1 has a male thread portion 7 of the joint cylindrical portion 6 which is entangled with the female thread portions 2 and 3 formed in the outer cylinder 1 in both directions. In other words, the male screw portion 7 is actually entangled with the female screw portion 2 in the same direction, but the improvement in the pulling direction of the tip cap 4 is described above. Another female screw portion 3 in the opposite direction to the male screw portion 7 acts as a stopper on the male screw portion 7. As a result, a firm and firm coupling state is maintained that the tip cap 4 does not rotate by rotating in the pulled direction.

이러한 결합상태에서 선단캡(4)을 역방향으로 강제회전시키면 그 역회전방향에 따은 외통(1)측의 한쪽방향암나사부(2)를 따라 숫나사부(7)가 안내되게 됨으로써 외통(1)에서 선단캡(4)이 원활히 빠져나오게 된다.When the tip cap 4 is forcedly rotated in the reverse direction in this coupling state, the male screw portion 7 is guided along the one-way female screw portion 2 on the outer cylinder 1 side according to the reverse rotation direction thereof. The tip cap 4 is smoothly pulled out.

한편 외통(1) 및 선단캡(4)은 적당한 탄성을 갖는 합성수지재로써 일체로 형성시켜지게 된다.Meanwhile, the outer cylinder 1 and the tip cap 4 are integrally formed of a synthetic resin material having moderate elasticity.

또 상기 실시예에서 숫나사부(7)는 외통(1)으로 눌려지는 방향을 향해 점차직경이 작아지는 테이퍼형상으로 형성되어져 있으나, 제5도에 도시된 바와같이 편재톱날모양으로 형성시켜 놓은 것이라도 좋은데, 이 경우 그들 모양에 맞춰 암나사부(2,3)를 형성시켜 놓게 되면 마찬가지 작용효과가 얻어지게 된다.In addition, in the above embodiment, the male screw portion 7 is formed in a tapered shape in which the diameter gradually decreases toward the pressing direction of the outer cylinder 1, but as shown in FIG. In this case, if the female screw portion (2, 3) is formed according to their shape, the same effect is obtained.

한편 본 실시에에서는 암나사부(2,3)를 격자모양으로 형성시켰으나, 그중 어느한쪽을 한쪽방향홈으로 형성시켜도 좋고, 또 홈모양 형상 대신 격자모양 또는 한쪽방향을 따라 예컨대 마름모꼴이나 직사각형 모양으로 된 여러개의 돌기라던가 원형모양으로 된 여러개의 돌기로 암나사부(3)을 형성시켜도 좋다.In the present embodiment, the female threads 2 and 3 are formed in a lattice shape, but either one of them may be formed in one direction groove, and instead of the groove shape, it is formed in a lattice shape or a rectangular shape, for example, in a rhombus or rectangular shape. The female thread part 3 may be formed by several protrusions or several protrusions of circular shape.

그리고 이와같은 여러개의 마름모꼴이나 직사각형모양, 원형모양으로 된 돌기를 적당히 돌출시켜 암나사부(3)를 형성시켜도 좋다.The female threaded portion 3 may be formed by appropriately projecting a plurality of lozenges, rectangles, and rounded projections.

이상과 같이 본 고안에 위하면, 외통의 앞끝쪽내주면에 격자모양암나사부가 형성되고 선단캡의 뒷끝에 이음원통부가 설치되면서 이 이음원통부 외주면에 상기 한쪽방향 암나사부와 같은 방향의 숫나사부가 형성되어져 있기 때문에, 외통의 앞끝쪽내부에다 선단캡의 이음원통부를 눌러 끼워주기만 하는 간단한 원터치조작으로도 이음원통부외주면의 한쪽방향 숫나사부가 외통내주면의 양방향 암나사부에 잇빨물림되고, 특히 필기구를 휴대할 경우와 같을 때 선단캡을 뽑아내는 방향으로 회전하는데 대해 외통의 이음원통부에서의 상기 선단캡의 숫나사부와 역방향이 되는 다른방향암나사부가 선단캡빠짐방지용 스토퍼로 작용하게 됨으로써, 외통앞끝에 선단캡이 확실하고 견고하게 결합시켜질 수가 있게 된다.According to the present invention as described above, while the lattice-shaped female screw portion is formed on the inner peripheral surface of the front end of the outer cylinder and the joint is formed on the rear end of the tip cap, the male screw portion in the same direction as the one-way female screw portion is formed on the outer peripheral surface of the joint cylinder. Therefore, even a simple one-touch operation that simply presses the joint cylinder of the tip cap into the inside of the front end of the outer cylinder, the male thread on one side of the outer circumferential surface of the joint is caught by the bidirectional female thread on the inner circumferential surface of the outer cylinder, especially when carrying a writing instrument. When the tip cap is rotated in the direction of extracting the tip cap, the opposite direction of the male screw portion opposite to the male screw portion of the tip cap in the joint cylinder portion of the outer cylinder acts as a stopper for preventing the tip cap from falling out. It can be combined firmly and firmly.

그 때문에 샤아프펜슬등과 같은 필기구를 조립할 때 선단캡의 나사끼움작업이 필요없게 되어 이런종류의 필기구의 생산성향상에 크게 기여하게 되고, 또 필기구를 휴대할 경우와 같을 때 선단캡을 분산할 염려가 없게 된다.This eliminates the need for screwing the tip cap when assembling writing instruments such as mechanical pencils, greatly contributing to the productivity improvement of this kind of writing instrument, and dispersing the tip cap when carrying writing instruments. There will be no.
