Description

작아지지 않는 연필{a pencil that won't shrink}A pencil that won't shrink

본 발명은 연필을 사용할 때 점점 짧아지며 몽당연필이 되어 사용하기 불편한 상황을 예상하여 불편을 덜기 위한 보조 장치에 관한 것이다.The present invention relates to an auxiliary device for anticipating an inconvenient situation in which a pencil becomes shorter and shorter when using a pencil and becomes inconvenient to use.

이 발명품이 없었을 당시에는 몽당연필을 사용할 때의 불편함이 다소 컸다. 연필의 잔여 부분이 많이 남아있더라도 다 사용하지 못하는 경우가 잦았다. 그리하여 낭비하게 되는 연필 개수는 점점 늘어났다.When this invention did not exist, the inconvenience of using the Mongdang pencil was rather great. Even if there was a lot of leftover part of the pencil, it was often impossible to use it all. Thus, the number of wasted pencils gradually increased.

연필의 잔여 부분이 많이 남아있음에도 불구하고, 전부 사용하지 못하고 버리게 되는 연필들을 조금이라도 더 사용할 수 있도록 하는 것을 목적으로 한다.The purpose of this is to make use of even a little more of the pencils that are thrown away without being able to use them all despite the fact that a lot of the remaining part of the pencil remains.

위에서 설명한 고정부는 통체에 형성된 나사 구멍과 이와 결합되는 고정나사로 구성되는데, 나사 구멍은 구멍 주위의 살두께가 통체의 살두께보다 두껍게 가공되는 것을 특징으로 하고, 이 나사 구멍에 결합되는 고정 나사는 나사 구멍과 결합한 후 나사산이 형성된 나사부의 끝을 나사부의 직경보다 크도록 가공하여, 나사를 다 풀어도 나사 구멍으로부터 분리되지 않는 것을 특징으로 한다. 이 발명에 따르면, 위와 같이 구성되는 고정부의 고정나사로써 삽입된 몽당연필을 고정한다.The fixing part described above consists of a screw hole formed in the cylinder and a fixing screw coupled thereto, the screw hole is characterized in that the thickness around the hole is processed to be thicker than the flesh thickness of the cylinder, and the fixing screw coupled to the screw hole is a screw After combining with the hole, the end of the threaded part is processed to be larger than the diameter of the threaded part, and it is characterized in that it is not separated from the threaded hole even if all the screws are loosened. According to the present invention, the inserted Mongdang pencil is fixed with the fixing screw of the fixing part configured as above.

본 발명은 기존에 전부 사용하지 못하고 버리게 되는 연필들을 사용할 수 있는 부분이 조금 더 늘게 되어 환경적으로도 매우 좋고, 편리하기도 한 발명이다.The present invention is an environmentally friendly and convenient invention, as the number of pencils that can be used is increased a little more than the existing unused and discarded pencils.

Figure 1c is a modified example of the fixing screw coupling portion shown in Figure 1b

이 도면은 몽당연필이 삽입되는 통체에 고정나사가 결합됨을 나타내는 사시도이다. 도면과 같이 몽당연필이 삽입되는 구멍(7)에 가까운 위치의 통체에 나사구멍(5)이 뚫리고 이에 고정나사(6)가 체결되어, 삽입된 몽당연필(8)을 고정시킨다. 이렇게 고정나사로 연필을 고정하는 것은 공지 기술로서, 컴퍼스 등 제도용 구에 널리 이용되고 있다. 이 도면에서는 특히 고정나사(6)의 끝부분을 나사부의 직경보다 크게 가공하였기 때문에 고정나사를 끝까지 풀더라도 통체(1)에서 분리되지 않아 잃어버릴 염려가 없는 특징이 있다. 또한 나사 구멍(5)의 반대쪽에 뚫은 다른 구멍(2)를 통하여 나사부의 끝에 프레싱 등 처리를 함으로써 그 직경을 키울 수 있다. 이렇게 고정나사가 다 풀려도 빠지지 않게 하는 것은 당업계에서 통상의 지식을 가진 자라면 용이하게 실시할 수 있을 것이다. 또한 통체(1)의 살두께가 얇아서 나사 구멍(5)의 나사산과 고정나사(6)의 결합력이 약하기 때문에, 나사 구멍(5)의 주위에 버가공(burring)을 하여 양자의 결합력을 높이도록 하였다. 고정나사(6)의 끝부분에 연필 고정판을 부착하여 삽입되는 연필과의 접촉면적을 넓혀 연필을 보다 더 견고히 고정하고 연필에 흠집이 덜 생기도록 한 것을 나타낸다. 이 고정판은 고정나사와 고정판을 결합한 후 반대쪽 구멍을 통해 리벳 가공하여 부착할 수 있다. 또한 당업자라면 용이하게 실시할 수 있을 것이다. 이 몽당연필은 벤딩부에 걸려 몸체가 패이면서 통체(1)에 삽입되기 때문에, 몽당연필(8)이 통체(1) 내에서 헛돌지 않는다. 여기서, 연필의 몸체가 벤딩부에 의해 패여야 하기 때문에 통체(1)의 살두께는 되도록 얇은 것이 바람직하다. 이 부분에서는 연필 깎기 기계를 사용할 때에 아주 유용하다. 즉, 연필 깎기 기계에 연필을 넣어서 기계를 돌리더라도 연필이 통체의 원주 방향으로 단단하게 고정되기 때문에 연필이 헛돌지 않아, 위쪽 부근 볼트 고정 방식보다 훨씬 유리한 강점이 있다.This drawing is a perspective view showing that the fixing screw is coupled to the cylinder into which the Mongdang pencil is inserted. As shown in the figure, a screw hole 5 is drilled in the tubular body at a position close to the hole 7 into which the Mondang pencil is inserted, and the fixing screw 6 is fastened thereto to fix the inserted Mondang pencil 8 . Fixing a pencil with a set screw is a well-known technique and is widely used in drafting tools, such as compasses. In this figure, in particular, since the end of the set screw 6 is machined larger than the diameter of the screw portion, even if the set screw is loosened to the end, it is not separated from the cylindrical body 1 and there is no fear of losing it. In addition, the diameter can be increased by pressing the tip of the threaded portion through another hole 2 drilled on the opposite side of the screw hole 5 . In this way, even if the set screw is loosened, it will be easily carried out by a person of ordinary skill in the art. In addition, since the flesh thickness of the cylindrical body 1 is thin and the coupling force between the screw thread of the screw hole 5 and the set screw 6 is weak, burring is performed around the screw hole 5 to increase the coupling force of both. did. By attaching a pencil fixing plate to the end of the fixing screw 6, the contact area with the inserted pencil is widened to fix the pencil more firmly and to make the pencil less scratched. This fixing plate can be attached by riveting through the hole on the opposite side after combining the fixing screw and the fixing plate. In addition, those skilled in the art will be able to implement it easily. Since the Mondang pencil is inserted into the cylindrical body 1 while the body is dented by being caught by the bending part, the Mondang pencil 8 does not wander in the cylindrical body 1 . Here, since the body of the pencil must be dented by the bending part, the flesh thickness of the cylindrical body 1 is preferably as thin as possible. This section is very useful when using a pencil sharpener. That is, even if you put a pencil in the pencil sharpener and turn the machine, the pencil is firmly fixed in the circumferential direction of the cylinder, so the pencil does not rotate, which is much more advantageous than the bolt fixing method near the top.
