Abstract

본 발명은 샤프심의 인출장치에 관한 것이다.The present invention relates to a drawing device for sharp shims.

종래의 샤프연필은 정상의 머리(nob) 또는 샤프 상방 옆구리의 누름단추(push button)를 2~3 번 누르게 되어 있어서 손가락을 일일히 올리고 내리는 번거로움이 있었으나, 본 발명은 샤프의 하방을 잡은 손가락 밑 부분에 설치한 로울러(roller)(7)의 톱니(7')를 통상의 샤프심 인출봉(棒)(3)에 꽉끼운 심관(管)(2)의 원형 래크(rack)(4)에 맞물리게 하였기 때문에 로울러(7)를 위로 굴리기만 하면 심관(2)과 통상의 샤프심인출봉(3)이 함께 밑으로 밀리게 되므로 그 하단의 경사진 개폐구(3)로부터 샤프심(1)이 인출되는 작용을 한다.Conventional Sharp pencil has been pressing the push button of the normal head (nob) or sharp upper side (two or three times) to raise and lower the finger one by one, but the present invention is a finger holding the lower finger The teeth 7 'of the roller 7 mounted on the bottom part are connected to the circular rack 4 of the core pipe 2, which is tightly fitted to the normal sharp-core lead-out rod 3. Since it is engaged, the roller core 7 and the normal sharp seam draw bar 3 are pushed downward together by simply rolling the roller 7 upwards, so that the sharp seam 1 is pulled out from the inclined opening 3 at the bottom thereof. Do it.

따라서 종래와 같이 손가락을 위로 올리고 내리는 번거로운 결점이 제거되는 효과가 있다.Therefore, there is an effect that the cumbersome defect of lifting the finger up and down as in the prior art is removed.

본 발명은 샤프심의 인출장치에 관한 것이다.The present invention relates to a drawing device for sharp shims.

종래의 샤프연필은 정상 의 머리(nob)또는 옆구리의 누름단추(push button)를 2~3 번 간헐적으로 눌러서 심을 인출하게 되어 있어서 손가락을 일일히 위로 올리고 내리는 번거로운 결점이 있었다.
본 발명은 이상과 같은 결점을 해결할 목적으로 안출한 것으로 샤프의 하방손가락 끝부위에 설치한 로울러(roller)를 위로 굴리기만 하면 원추형촉 관 끝에서 샤프심이 인출되므로 손가락을 위로 올렸다 내리는 번거로움이 해소된다.
Conventional sharp pencil has been to draw the core by pressing the push button of the normal head (nob) or side two or three times intermittently, there was a cumbersome defect to raise and lower the fingers one by one.
The present invention has been made for the purpose of solving the above-mentioned shortcomings by simply rolling up the roller (roller) installed at the tip of the lower finger of the sharp, the sharp core is drawn out from the tip of the conical coffin tube, thereby eliminating the hassle of raising and lowering the finger. do.

샤프연필을 잡은 손가락 끝 부위에 설치한 로울러 표면의 톱니는 미세하게 형성해서 손가락의 접촉감을 좋도록 하고, 심관(管)둘레에 형성한 원형의 래크(rack)에는 로울러 표면의 톱니가 정확하게 잘 물리도록 한다.The teeth on the surface of the roller installed at the tip of the finger holding the sharp pencil are finely formed to improve the contact feeling of the fingers, and the teeth on the surface of the roller are precisely fixed on the circular rack formed around the core tube. To do that.

통상의 샤프심 인출봉(棒)(3)에 꽉 끼운 심관(2)의 하방둘레에 원형의 래크(rack)(4)를 형성하고 외관(5)의 하방에 뚫린 사각공(四角孔)(6)에는 톱니(7')형성의 로울러(roller)(7)를 그 축(8)이 축(軸)홈(9)에서 빠지지 않도록 설치하고 그 톱니(geartooth)(7')가 심관(管)(2)의 래크(rack)(4)에 맞물리게 한 것이다.Square holes (4) formed in a circular rack (4) in the lower circumference of the core tube (2) tightly fitted to the normal sharp core extraction rod (3) (6) (6) ), A roller (7 ') forming roller (7') is installed so that the shaft (8) does not come out of the shaft groove (9) and the tooth (7 ') is a core tube. It is engaged with the rack (4) of (2).

도면중 미설명 부호 3' 는 샤프심 인출봉(3)하단의 개폐구(開閉口) 10 은 스프링, 11은 기공판(基孔板), 12는 원추형 촉 관을 표시한 것임.In the figure, reference numeral 3 'indicates the opening of the lower end of the sharp core extraction rod 3, spring 10, pore plate 12, and conical contact tube 12.

이상과 같이 구성된 본 발명의 작용을 도면에 의거 상세히 설명하면 다음과 같다.
통상의 샤프심(1)인출봉(3)에 꽉 끼운 심관(2)하방에 원형의 래크(rack)(4)를 형성하고, 외관(5)의 하방에 뚫린 사각공(四角孔)(6)에는 톱니(7')형성의 로울러(roller)(7)를 그 축(8)이 축 홈(9)에서 빠지지 않토록 설치하고 그 톱니(geartooth)(7')가 심관(2)의 래크(rack)(4)에 정확히 맞물리게 하였기 때문에 로울러(7)를 화살표 방향인 위로 굴려서 심관(2)과 함께 샤프심(1)인출봉(3)을 하강운동케 하면, 통상의 원추형 촉 관(12)으로 고정시킨 통상의 기공판(基孔板)(11)상의 스프링(10)이 수축되면서 통상의 샤프심(1)인출봉(3)하단의 경사진 개폐구(開閉口)(3')가 기공판(11)의 구멍 밖으로 돌출하면서 벌어지는 순간 샤프심(1)이 약간 인출된다.
Referring to the operation of the present invention configured as described above in detail as follows.
Square holes (4) formed in the bottom of the core pipe (2) tightly fitted to the normal sharp core (1) pullout rod (3), and drilled below the exterior (5) (6) The roller (7 ') forming roller (7') is installed so that the shaft (8) does not come out of the shaft groove (9) and the gear (7 ') is the rack of the core (2) ( Because the roller (4) is engaged correctly, the roller (7) is rolled upward in the direction of the arrow, and the sharp shim (1) withdrawal bar (3) is lowered together with the core tube (2). As the spring 10 on the normal pore plate 11 fixed is contracted, the inclined opening and closing opening 3 'at the lower end of the normal sharp core 1 drawing-out rod 3 is provided with the pore plate ( The sharp shim 1 is pulled out slightly at the moment when it protrudes out of the hole of 11).

이와 같이 통상의 이 샤프심(1)인출봉(3)하단의 경사진 개폐구(3')는 3~4 개소 짜개져서 그 선단이 기공판(11)구멍 밖으로 돌출할 때 벌어지는 순간 샤프심(1)을 약간 끌어내리다가 구멍이 샤프심(1)굵기 보다 더 커지면 정지된다. 그리고 굴리던 로울러(7)에서 손가락을 떼자마자 수축되었던 스프링(10)이 원상복귀하면서 그 개폐구(3')는 가공판(11)구멍속으로 몰입하면서 오그라져서 샤프심(1)을 강력히 잡아 주게 된다.Thus, the inclined opening and closing opening 3 'of the lower end of this sharp shim 1 withdrawal 3 is squeezed into three to four places, and the sharp shim 1 is opened when its tip protrudes out of the hole of the hole plate 11. It pulls down slightly and stops when the hole becomes larger than the sharp shim 1. As soon as the finger 10 is released from the rolled roller 7, the contracted spring 10 returns to its original state, and the opening and closing hole 3 'is immersed and crushed into the hole of the processing plate 11 to strongly hold the sharp shim 1. .

이상과 같이 본 발명은 외관(5)을 잡은채로 그 하방에 설치한 로울러(roller)(7)를 손가락 끝 동작만으로 약간 전동(轉動)시켜서 샤프심(1)을 인출케 하기 때문에 손가락을 위로 올리고 내리는 번거로움이 해소 된다.As described above, according to the present invention, the roller 7 installed below the grip 5 is slightly driven by only a fingertip movement to draw out the sharp shim 1 so that the finger is raised and lowered. The hassle is eliminated.

그리고 로울러(7)의 톱니(7')는 미세하게 하게 형성되었기 때문에 로울러(7)를 돌리는 촉감이 좋고 손가락이 미끄러지지 않는다.And since the teeth 7 'of the roller 7 are finely formed, the feel of turning the roller 7 is good and the fingers do not slip.

본 발명은 외관(外管)하방의 손가락 끝부위에 로울러(7)가 설치되어 있어서 굴리게 되기 때문에 종래와 같이 손가락을 일일히 위로 올리고 내리는 번거로움이 해소되고 또 로울러(7)의 톱니(7')는 심관(2)의 하방의 둘레에 형성한 원형의 래크(4)에 정확히 맞물려 있어서 샤프심(1)인출봉(3)과 함께 하강운동하므로 샤프심(1)이 확실하게 인출되는 효과가 있다.In the present invention, since the roller (7) is installed at the fingertip of the lower side of the outer pipe, the roller (7) is rolled and rolled up. ') Is accurately engaged with the circular rack 4 formed around the lower portion of the core pipe 2, and the downward movement with the sharp shim 1 and the withdrawing rod 3 has the effect that the sharp shim 1 is reliably drawn out. .
