본 고안은 원통형상캡을 회전시키면 지우개고무가 원통체의 뒤쪽으로부터 조금씩 나오게됨과 더불어, 원통체를 녹크하게 되면 필심이 선단캡으로부터 조금씩 송출되어져 나오도록 된 샤아프펜슬에 관한 것이다.The present invention relates to a mechanical pencil that is to be released from the back of the cylinder little by little by rotating the cylindrical cap, and also to knock the cylindrical body out of the tip cap little by little.
종래의 샤아프펜슬은 필기부재의 필심저장탱크에 끼워 넣어진 지우개고무받침대로부터 녹크캡을 벗겨내어 지우개고무를 사용하다가, 지우개고무를 사용하지 않을때에는 지우개고무받침대에 부착된 녹크캡을 녹크하여 필심을 선단캡으로부터 조금씩 내보낼 수 있도록 구성되어져 있었다.Conventional mechanical pencil peels off the knock cap from the eraser rubber support inserted into the pencil storage tank of the writing member and uses the eraser rubber.When the eraser rubber is not used, the knock cap attached to the eraser rubber support is knocked and peeled. It was configured to allow the shim to be released little by little from the tip cap.
그러나 상기와 같은 종래의 샤아프펜슬에서는 지우개 고무를 조금씩 내보낼 수가 없었기 때문에, 지우개고무가 닳은 경우에는 그때마다 지우개고무받침대로부터 지우개고무보유지지구를 뽑아내어, 이 보유지지구를 벌려 지우개고무가 닳은 분량만큼 빼낸다음 보유지지구를 조여 지우개고무받침대에다 끼워넣어야하는 번잡한 작업이 되풀이되는 번거로움이 있었다.However, since the eraser rubber could not be discharged little by little in the conventional pencil pencil as described above, when the eraser rubber was worn out, the eraser rubber holding support was removed from the eraser rubber support each time, and the holding support was opened to open the eraser rubber. There was a lot of repetition of the complicated work of pulling out the amount and tightening the retainer into the eraser rubber support.
이에 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 도시된 바와 같은 선단캡(1)을 갖는 필기부재(2)를 선단캡(1)이 돌출시켜지는 상태로 외통(3)내에 수납설치하고서, 원통형상캡(19)의 앞부위 내면 및 뒷부위 내면에 각각 계단부(4) 및 나선홈(5)을 형성시키고, 원통체(6)의 앞쪽부분(6a)내에 상기 필기부재(2)의 필심저장탱크(8)와 닿게 되는 받침부(9)를 설치해서, 외통(3)의 뒤쪽부위 내면에 대해 이 원통체(6)의 앞쪽부분(6a)이 축방향으로는 자유로히 이동하지만 회전방향으로는 제동되도록 구성됨과 더불어, 이 원통체(6)의 뒤쪽부분(6b)에는 슬릿(10)이 형성되어 이 슬릿(10)에 지우개고무받침대(11)가 자유로이 미끄럼이동할 수 있도록 끼워넣어진 구성으로 되어 있다.The present invention has been devised to solve the above problems, and the writing member 2 having the tip cap 1 as shown in the housing is installed in the outer cylinder 3 in a state where the tip cap 1 protrudes. Then, the step portion 4 and the spiral groove 5 are formed on the inner surface of the front portion and the rear portion of the cylindrical cap 19, respectively, and the writing member 2 in the front portion 6a of the cylindrical body 6. By installing the supporting portion 9 which comes into contact with the core storage tank 8 of the cylinder, the front portion 6a of the cylindrical body 6 moves freely in the axial direction with respect to the inner surface of the rear portion of the outer cylinder 3. In addition to the braking in the rotational direction, the rear portion (6b) of the cylindrical body 6 is formed with a slit (10) is inserted into the slit (10) so that the eraser rubber base (11) can slide freely It is in a binary configuration.
이와 같이 구성된 본 고안은, 원통형상캡(19)을 회전시키면, 외통(3)의 뒤쪽부위에 대해 원통체(6)의 앞쪽부분(6a)이 축방향으로는 자유로이 이동하지만 회전방향으로는 제동되게 되고, 또 원통제(6)의 뒷부분(6b)의 슬릿(10)에 지우개고무받침대(11)가 자유로이 미끄럼이동할수 있도록 끼워넣어져 있기 때문에 지우개고무받침대(11)가 원통체(6)의 슬릿(10)을 따라 안내되어지면서 축방향으로 이동해서 지우개고무받침대(11)에 설치된 지우개고무(13)가 회전방향에 대응해서 원통체(6)로부터 출몰시켜지게 된다.According to the present invention configured as described above, when the cylindrical cap 19 is rotated, the front portion 6a of the cylindrical body 6 moves freely in the axial direction with respect to the rear portion of the outer cylinder 3, but brakes in the rotational direction. In addition, since the eraser rubber support 11 is inserted into the slit 10 of the rear portion 6b of the cylindrical agent 6 so as to be able to slide freely, the eraser rubber support 11 is a slit of the cylindrical body 6. Guided along (10) and moved in the axial direction, the eraser rubber 13 installed in the eraser rubber support 11 is released from the cylindrical body 6 corresponding to the rotational direction.
또 원통체(6)의 뒷끝을 녹크하게 되면 원통형상캡(19)과 함께 이 원통체(6)의 받침부에 닿게 된 필심저장탱크(8)가 스프링(20)에 대항하거나 또는 그 탄발력에 의해 앞쪽 또는 윗쪽으로 이동해서 공지의 샤아프펜슬과 마찬가지로 척(21)개폐에 따라 필심(22)을 선단캡(1)으로부터 조금씩 내보낼 수가 있게 된다.When the rear end of the cylindrical body 6 is knocked, the lead storage tank 8 which comes into contact with the cylindrical portion 19 and the supporting portion of the cylindrical body 6 is opposed to the spring 20 or the elastic force thereof. As a result, the pendulum 22 can be moved out of the tip cap 1 little by little depending on the opening and closing of the chuck 21 as in the known mechanical pencil.

(5) is formed.
그리고 참조부호 6은 원통형상캡(19)의 뒷 끝에 끼워지는 원통체로써, 이 원통체(6)의 대략 중앙부위 외면에는 돌출편(10)이 형성되어 이 돌출편(10)이 원통형캡(19)의 계단부(4)에 걸려지게 되고, 또 이 원통제(6)의 앞쪽부(6a)내에는 필기부재(2)의 필심저장탱크(8)에 닿게 되는 받침부로서 예컨대 받침판(9)이 설치되어 있다.And reference numeral 6 is a cylindrical body fitted to the rear end of the cylindrical cap 19, a protrusion 10 is formed on the outer surface of the substantially central portion of the cylindrical body 6, the protrusion 10 is a cylindrical cap (19) And a support plate (9), which is caught by the staircase (4) and touches the lead storage tank (8) of the writing member (2) in the front (6a) of the cylindrical agent (6). Is installed.
한편, 상기 외통(3)의 뒤쪽부위 내면에는 다각형부(17)가 형성되고, 상기 원통체(6)의 앞쪽부위(6a)외주에는 상기 다각형부(17)에 끼워지는 다각형부(18)가 형성되어져 있어서, 외통(3)의 뒤쪽부위에 대해 원통체(6)의 앞쪽부분(6a)이 축방향으로는 자유로이 이동할 수 있으나, 회전방향으로는 제동되어지게 된다.On the other hand, the polygonal portion 17 is formed on the inner surface of the rear portion of the outer cylinder 3, the polygonal portion 18 to be fitted to the polygonal portion 17 on the outer periphery of the front portion 6a of the cylindrical body 6 The front portion 6a of the cylindrical body 6 can move freely in the axial direction with respect to the rear portion of the outer cylinder 3, but is braked in the rotational direction.
여기서 상기 외통(3)의 뒤쪽부위에 대해 원통체(6)의 앞쪽부분(6a)이 축방향으로 자유로이 이동할수 있으나 회전방향으로는 제동되어지도록 하는 수단으로서는, 본 실시예에서와 같은 다각형부(17, 18)로 된 수단에만 한정되지 않고, 예컨대, 키이홈과 키이로 이루어지는 수단으로 하여도 좋다.Here, as a means for allowing the front portion 6a of the cylindrical body 6 to move freely in the axial direction with respect to the rear portion of the outer cylinder 3, it is to be braked in the rotational direction. It is not limited to the means of 17 and 18), for example, may be a means consisting of a key groove and a key.
그리고 상기 원통체(6)의 뒤쪽부분(6b)에는 서로 마주보는 부분에 슬릿(10)이 형성되면서, 이들 양 슬릿(10)에는 슬릿(10)에 끼워진 지우개고무받침대(11)의 2개의 협지편(12)이 뒤쪽을 향해 자유로이 미끄럼이동할수 있도록 끼워넣어져 있는바, 이 협지편(12)에 지우개고무(13)가 물어잡혀지게 됨과 더불어 원통형캡(19)의 나선홈(5)에 상기 각 협지편(12)에 형성된 돌기(14)가 끼워맞춰지도록 되어 있다.And while the slits 10 are formed at the rear portions 6b of the cylindrical body 6 facing each other, these two slits 10 have two nips of the eraser rubber support 11 fitted to the slits 10. The piece 12 is inserted so as to be able to slide freely toward the rear, and the eraser rubber 13 is caught in the clamping piece 12 and the spiral groove 5 of the cylindrical cap 19 is located above. The projections 14 formed on the respective sandwich pieces 12 are fitted.
여기서 참조부호 25와 26은 상기 슬릿(10)의 앞, 뒤부위에 형성된 지우개고무받침대(11)의 환상스톱퍼로써, 그 때문에 상기 지우개고무받침대(11)가 이들 슬릿(10)의 앞, 뒤부위 환형스톱퍼(25, 26)에 닿을 때까지 축방향으로 이동할 수 있게 된다.Here, reference numerals 25 and 26 are annular stoppers of the eraser rubber support 11 formed at the front and rear portions of the slit 10, so that the eraser rubber support 11 is located at the front and the rear of these slits 10. It can move in the axial direction until it reaches the annular stoppers 25 and 26.
다음에는 상기와 같이 구성된 본 실시예 샤아프펜슬을 조립하는 방법에 대해 설명한다.Next, a method of assembling the present embodiment mechanical pencil configured as described above will be described.
먼저 원통체(6)의 슬릿(10) 양쪽을 바깥쪽으로 휘어지게 해서 이슬릿(10)에 지우개고무받침대(11)의 양 협지편(12)이 뒤쪽을 향하도록 원통체(6)내에다 끼워설치하고서 이들 양 협지편(12)이 상기 양 슬릿(10)에 자유로이 이동할수 있게 끼운다.First, both slits 10 of the cylindrical body 6 are bent outwardly and inserted into the cylindrical body 6 so that both clamping pieces 12 of the eraser rubber support 11 face the rear side of the slits 10. The two sandwiching pieces 12 are fitted to the two slits 10 so as to move freely.
이어 지우개고무(13)를 원통체(6)뒤끝으로부터 삽입해서 양 협지편(12)에 물어잡히게 하고서 이 원통체(6)를 원통형상캡(19)의 뒤끝에 끼워 눌러넣게 되면, 돌출편(19)이 안쪽으로 휘어져 원통형상캡(19)의 계단부(4)를 타고 넘어 이 계단부(4)에 걸려지게 된다.Then, the eraser rubber 13 is inserted from the rear end of the cylindrical body 6 so as to be caught by both clamping pieces 12, and the cylindrical body 6 is pressed into the rear end of the cylindrical cap 19. Then, the projecting piece 19 ) Is bent inward to ride over the step (4) of the cylindrical cap 19 is caught by this step (4).
이때 상기 지우개고무(13)가 양 협지편(12)에 물어잡혀지도록 하는 것을 원통체(6)를 원통형캡(10)에다 조립한 다음에 하여도 좋다. 이렇게 해서 상기 원통체(6)를 원통형상캡(19)에 조립하는 것이 끝나게 되면, 원통체(6)의 환형스톱퍼(26)가 원통형상캡(16)의 뒤끝에 닿은 상태로 되는바, 여기서 이와 같은 상태가 되도록 부품칫수가 결정되어져 있다함은 구태어 설명할 필요도 없다.At this time, the cylindrical rubber 6 may be assembled to the cylindrical cap 10 so that the eraser rubber 13 may be caught by both clamping pieces 12. In this way, when the cylindrical body 6 is finished assembling the cylindrical cap 19, the annular stopper 26 of the cylindrical body 6 is in contact with the rear end of the cylindrical cap 16, where such It is not necessary to explain that the parts dimensions are determined so as to be in a state.
이어 이 원통형상캡(19)을 잡고 원통체(6)의 앞쪽부분(6a) 외면에 형성된 다각형부(18)를 외통(3)의 뒤쪽부위 내벽에 형성된 다각형부(17)에다 끼워넣게 되면 샤아프펜슬의 조립이 끝나게 되는바, 이 경우 상기 외통(3)의 뒤쪽으로 원통체(6)가 빠져나가지 않도록 강하게 끼워넣어주어야 함은 물론이다.Then, the cylindrical cap 19 is grasped and the polygonal portion 18 formed on the outer surface of the front portion 6a of the cylindrical body 6 is inserted into the polygonal portion 17 formed on the inner wall of the rear portion of the outer cylinder 3. Assembly of the pencil is completed, in this case, of course, the cylinder 6 should be inserted into the rear of the outer cylinder 3 so as not to be strongly pushed out.
다음에는 상기와 같이 구성된 본 고안 샤아프펜슬의 작용에 대해 설명한다.Next will be described the operation of the subject innovation mechanical pencil configured as described above.
지우개고무(13)를 사용하지 않을 때에는 제 1 도에 도시된 바와같이, 지우개고무받침대(11)가 원통체(6) 앞부분 환형스톱퍼(25)에 닿아, 지우개고무(13)의 앞끝이 원통체(6)의 뒤쪽부위 환형스톱퍼(26)의 끝면과 정확히 일치되는 상태가 된다.When the eraser rubber 13 is not used, as shown in FIG. 1, the eraser rubber support 11 contacts the annular stopper 25 in front of the cylindrical body 6 so that the front end of the eraser rubber 13 is cylindrical. (6) is in a state exactly coinciding with the end surface of the annular stopper 26.
이 상태에서 상기 원통형캡(19)을 회전시키면, 외통(3)의 뒤쪽부위에 대해 원통체(6)의 앞쪽부분(6a)이 축방향으로는 자유로이 이동하지만 회전방향으로는 제동시켜지게 되고, 또 원통형상캡(19)의 나선홈(5)에 지우개고무받침대(11)의 협지편(12)에 형성된 돌기(14)가 끼워맞춰져 있기 때문에 지우개고무받침대(11)가 그 2개의 협지편(12)이 끼워넣어진 원통체(6)의 양 슬릿(10)을 따라 안내되어 지면서 축방향으로 이동해서, 지우개고무받침대(11)의 2개의 협지편(12)에 물어잡혀진 지우개고무(13)를 회전방향에 대응해서 원통체(6)로부터 출몰시킬수가 있게 된다.When the cylindrical cap 19 is rotated in this state, the front portion 6a of the cylindrical body 6 moves freely in the axial direction with respect to the rear portion of the outer cylinder 3, but brakes in the rotational direction. In addition, since the projections 14 formed on the sandwich pieces 12 of the eraser rubber support 11 are fitted into the spiral grooves 5 of the cylindrical cap 19, the eraser rubber support 11 is the two sandwich pieces 12. Is moved along the slit 10 of the cylindrical body 6 to which the cylindrical body 6 is inserted, and moves in the axial direction so that the eraser rubber 13 caught by the two sandwiching pieces 12 of the eraser rubber support 11. Can be projected from the cylindrical body 6 corresponding to the rotational direction.
또 원통체(6)의 뒤끝을 녹크하게 되면, 원통형캡(19)과 함께 원통체(6)의 받침판(9)에 닿아져 있는 필심저장탱크(8)가 스프링(20)에 대항하거나 그 탄발력에 의해 앞쪽 또는 뒤쪽으로 이동해서 공지의 샤아프펜슬과 마찬가지로 척(21)의 개폐에 따라 필심(22)을 선단캡(1)으로부터 조금씩 내보낼수가 있게 된다.When the rear end of the cylindrical body 6 is knocked, the lead storage tank 8 which is in contact with the support plate 9 of the cylindrical body 6 together with the cylindrical cap 19 is opposed to or burnt out of the spring 20. It moves to the front or the back by the force, and like the well-known mechanical pencil, it is possible to send the pen core 22 little by little from the tip cap 1 as the chuck 21 opens and closes.
한편 상기 지우개고무(13)를 조금씩 내보내는 것은, 원통형상캡(19)을 회전시켜 지우개고무받침대(11)를 축방향(도면에서는 오른쪽방향)으로 이동시켜줌으로서 지우개고무(13)가 닳은 양 만큼 내보내지게 되고, 사용한 후에는 원통형상캡(19)을 역회전시켜 지우개고무받침대(11)를 왼쪽방향으로 이동시켜주게 되면 지우개고무(13)가 끌어 들여질 수 있게 된다.On the other hand, the eraser rubber 13 is to be discharged little by little, by rotating the cylindrical cap 19 to move the eraser rubber support 11 in the axial direction (right direction in the drawing) so that the eraser rubber 13 is discharged by the amount worn out. After the use, the cylindrical cap 19 is rotated in reverse to move the eraser rubber support 11 to the left direction so that the eraser rubber 13 can be pulled out.
이상 설명한 바와 같이 본 고안에 의하면, 외통(3)에 대해 원통형상캡(19)을 회전시켜줌으로서 지우개고무받침대(11)를 축방향으로 이동시킬수가 있어, 지우개고무(13)를 회전방향에 대응해서 원통체(6)로부터 출몰시킬수가 있기 때문에, 글자를 지울 때 지우개고무(13)를 필요량만큼 조금 내보내어 글자를 지울 수가 있게 되고, 지우개고무를 사용하지 않을 때에는 지우개고무(13)를 끌어들일수가 있게 됨으로써, 원통형상캡(19)의 회전조작하는것 만으로도 지우개고무(13)를 간편히 출몰시킬 수가 있게 된다. 그 때문에 종래와 같은 번거로운 조작을 되풀이할 필요가 없어 편리할 뿐만 아니라, 또 부품수도 적어져 값싸게 제작할 수 가 있게 된다.As described above, according to the present invention, by rotating the cylindrical cap 19 with respect to the outer cylinder 3, the eraser rubber support 11 can be moved in the axial direction, so that the eraser rubber 13 corresponds to the rotational direction. Since it can be haunted from the cylindrical body 6, the eraser rubber 13 can be removed as much as necessary when the character is erased, and the character can be erased. When the eraser rubber is not used, the eraser rubber 13 can be drawn in. As a result, the eraser rubber 13 can be easily sunk by simply rotating the cylindrical cap 19. Therefore, it is not necessary to repeat the cumbersome operation as in the prior art, and it is not only convenient, but also the number of parts can be reduced, so that the manufacturing can be made cheap.
