Description

샤프심의 인출장치 {Apparatus for with drawing Lead in sharp pencil}Sharpshim's Drawer {Apparatus for with drawing Lead in sharp pencil}

본 고안은 샤프펜슬로 글씨를 쓸때 간편하게 샤프심을 인출할 목적으로 안출한 것이다.The present invention is designed for the purpose of withdrawing sharp shim when writing with a pencil.

종래의 샤프 펜슬은 정상의 노브(Nob)또는 옆구리의 누름단추(push button)를 2~3번 간헐적으로 누르게 되어 있어서 손가락을 올리고 내리는 번거로움이 있었으나 본 고안은 샤프의 하방 손가락 끝 부위에 설치한 피니언형 로울러(pinion Type roller)를 상하로 굴리기만 하면 샤프심이 인출되고 종래 샤프에 있는 스프링은 생략되므로 조립공정이 간략해지고 또 손가락을 올리고 내리는 번거로움이 해소되어 편리하다.Conventional mechanical pencils have a problem of raising and lowering the finger by intermittently pressing the Nob or push button of the side two or three times, but the present invention has been installed at the lower finger tip of the sharp. By simply rolling the pinion type roller (pinion type roller) up and down, the sharp seam is pulled out and the spring in the conventional sharp is omitted, simplifying the assembly process and eliminating the hassle of raising and lowering the fingers.

본 고안은 상술한 바와 같은 종래기술의 결점을 제거하기 위하여 안출한 것으로 샤프펜슬의 하방 손가락 끝 부위에 설치한 피니언형 로울러의 치형(齒形)을 로우렛트작업(knurling)의 개념으로 그 톱니(gear tooth)의 피치(pitch)와 톱니끝 높이, 톱니뿌리 높이 등을 낮게 하여 손가락의 접촉감을 좋도록 형성하고, 심관(管)의 하방에 환설(環設)한 래크(rack)도 피니언형 로울러의 톱니에 잘 맞물리도록 형성한다.The present invention has been devised to eliminate the drawbacks of the prior art as described above, and the teeth of the pinion rollers installed at the lower fingertips of the mechanical pencil have the concept of knurling. The pitch, tooth tip height, and tooth root height of the gear tooth are lowered to form a good contact feeling of the fingers, and the racks connected to the lower part of the core pipe are also pinion type rollers. It should form well with the teeth of the teeth.

샤프펜슬 중심선상의 심(1)관(2)(또는 샤프심(1) 지지봉(3))하방에 래크(rack)(4)를 환설(環設)하고 외관(5)의 하방에 천설한 각공(角孔)(6)에는 피니언(pinion)형 로울러(roller)(7)를 그 축(8)이 축홈(9)에 감입토록 설치하여, 롤러(7)의 톱니(geartooth)(7')가 래크(rack)(4)에 맞물리게 하여서 된 것이다.Angle hole which opened the rack 4 under the core (1) pipe (2) (or the sharp core (1) support bar (3)) on the mechanical pencil center line, and laid it below the exterior (5). (Iii) 6, a pinion roller 7 is provided so that the shaft 8 is indented in the shaft groove 9, so that the gear 7 of the roller 7 is 7 '. By engaging the rack (4).

미설명 부호 10은 스프링, 11은 기공판(基孔板), 12은 원추형 촉관을 표시한 것임.Reference numeral 10 denotes a spring, 11 a pore plate, and 12 a conical contact tube.

이상과 같이 구성된 본 고안의 작용을 도면에 의거 상세히 설명하면 다음과 같다. 통상의 샤프심(1)지지봉(支持捧)(3)에 삽입된 통상의 심관(2)하방에 래크(rack)(4)를 형성하고, 외관(5)의 하방에 천설한 각공(角孔)(6)에는 피니언(pinion)형 로울러(roller)(7)를 그 축(8)이 축홈(9)에 감입토록 개입(介入)하여 그 톱니(gear tooth)(7')가 심관(2)의 래크(rack)(4)에 맞물리게 하였기 때문에 로울러(7)를 화살표 방향인 위,아래로 굴려서 샤프심(1)지지봉(3)을 하강 운동케 하면, 통상의 원추형 촉관(12)으로 고정시킨 통상의 기공판(基孔板)(11)상의 스프링(10)이 수축되고, 샤프심(1)지지봉(3)하단의 경사진 죠우(Jow)는 기공판(11)의 구멍 밖으로 돌출하면서 탄력적으로 확개(擴開) 작용을 한다. 이와 같이 통상의 이 샤프심(1)지지봉(3)의 경사진 하단은 2~3 개소 쪼개진 죠우(Jow)를 구성 하고 있어 그 선단이 탄성으로 벌어져 샤프심(1)공이 확대토록 되어 있기 때문에, 이 죠우(Jow)가 기공판(11) 구멍속으로 몰입할 때는 오므라져서 샤프심(1)을 꽉잡아 주게 되고 기공판(11)구멍밖으로 돌출할 때는 샤프심(1)이 약간 진출하다가 구멍이 확개하는 순간 심(1)의 진출이 멈추는 작용을 하는 것이다.Referring to the operation of the present invention configured as described above in detail based on the drawings as follows. Square hole (1) A rack (4) is formed below the normal core pipe (2) inserted into the supporting rod (3), and a hollow hole is installed below the exterior (5). (6), the pinion roller (7) is inserted so that the shaft (8) is infiltrated into the shaft groove (9), the tooth tooth (7 ') is the core tube (2) Since the rollers 7 are engaged with the racks 4 of the rollers, the rollers 7 are rolled up and down in the direction of the arrow to make the sharp shim 1 support rods 3 move downward. The spring 10 on the pore plate 11 is contracted, and the inclined jaw at the lower end of the sharp shim 1 support rod 3 protrudes out of the hole of the pore plate 11 and expands elastically. (擴 開) to act. As such, the lower end of the inclined sharp shim 1 supporting rod 3 constitutes two or three split jaws, and the tip thereof is elastically opened so that the sharp shim 1 hole is enlarged. When (Jow) is immersed in the hole of the pore plate 11, it collapses and holds the sharp shim 1 tightly. (1) It stops advancing.

그리고 종래의 샤프는 심(1)을 인출 시키기 위하여 정상의 노브(Nob)에 손가락을 올려대고, 눌러야 하는 번거로움이 있지만, 본 고안은 외관(5)하방에 설치한 피니언형 로울러(Roller)(7)를 손가락 끝 동작만으로 전동(轉動)시켜서 샤프심(1)을 인출케 하기 때문에 손가락을 올리고 내리는 번거로움이 해소 된다.And the conventional sharp has a hassle to put a finger on the top of the knob (Nob) in order to pull out the shim (1), but the present invention has a pinion type roller (Roller) installed below the exterior (5) Since 7) is driven only by the fingertip movement, the sharp shim 1 is pulled out, thereby eliminating the trouble of raising and lowering the finger.

그리고 로울러(7)를 아래로 굴릴 때는 샤프심(1)지지봉(3)이 상승하는 바람에 그 끝의 경사진 죠우(Jow)가 기공판(11)의 구멍속으로 몰입하여 샤프심(1)을 꽉 잡아주는 작용을 하기 때문에, 종래 샤프에 있는 스프링(10)은 생략 해도 무방하므로 그만큼 조립공정이 간략해 지는 것이다.And when rolling the roller (7) down, the sharp shim (1) support rod (3) is raised, the inclined jaw (Jow) at the end of the immersion into the hole of the pore plate 11 to tighten the sharp shim (1) Since the holding function, the spring 10 in the conventional shaft may be omitted, so that the assembly process is simplified.

그런데 본 고안을 실시할때 스프링(10)을 샤프심 지지봉(3)에 개입해도 무방하지만 로울러(7)를 위로 굴릴때 약간 힘이 더 들게 되고, 아래로 굴릴때는 힘이 전혀 들지 않는다. 그리고 별도의 실시예로서 샤프심 지지봉(3)하방에 탄성과 마찰력이 큰 실리콘 튜브를 끼워서 피니언형 로울러(7)를 압접(壓接)케 해도 그 톱니의 자국이 남게 되므로 미끄럼(slip)이 방지되고 그 작용효과도 같게 된다.By the way, when implementing the present invention, the spring 10 may be involved in the sharp core support rod 3, but when the roller 7 is rolled up, it takes a little more force and does not take any force when rolling down. In addition, as a separate embodiment, even if the pinion roller 7 is press-fitted by inserting a silicone tube having a high elasticity and friction force under the sharp core support rod 3, the marks of the teeth remain, thereby preventing slipping. The effect is the same.

본 고안은 외관(外管)하방의 손가락 끝부위에 로울러(7)를 설치하여 위,아래로 굴리게 되어 있기 때문에 종래와 같이 손가락을 올리고 내리는 번거로움이 해소되는 편리점이 있고, 또 로울러(7)의 톱니(7')가 래크(4)에 맞물려 있어서 샤프심(1)지지봉(3)의 하강운동으로 샤프심 인출이 확실해 지고 또 종래 샤프펜슬내의 스프링(10) 생략도 가능하므로 조립 공정이 더욱 간략해 지는 효과가 있다.In the present invention, since the roller (7) is installed at the fingertip below the outer pipe and rolls up and down, there is a convenience store that eliminates the trouble of raising and lowering the finger as in the related art. ), The teeth 7 'are engaged with the rack 4, so that the sharp shim can be pulled out by the downward movement of the sharp shim 1, the supporting rod 3, and the spring 10 in the conventional pencil can be omitted. Termination is effective.
