Abstract
본 발명은 샤프심을 넣어 저장할 수 있는 샤프심 탱크(1), 상기 샤프심 탱크(1)에서 나오는 샤프심 길이를 조절하는 클러치(2)로 구성하는 것을 특징으로 하는 샤프심이 걸리지 않는 샤프. 본 발명은 샤프로 필기 중 샤프 클러치에 샤프심이 끼어 사용하지 못하는 것을 방지해 주는 효과를 갖고 있다. 특히 필기시험 등 작성 중 중요한 순간에 샤프 클러치에 샤프심이 끼는 것을 예방할 수 있다. 기존 샤프펜슬에 간단하고 가벼운 부품만 추가해 부담스럽지 않고 샤프심 탱크 크기를 늘려 샤프심을 조금이라도 더 저장할 수 있는 샤프펜슬을 제공한다.The present invention is a mechanical pencil that does not get caught in the lead, comprising a lead tank (1) into which the lead can be stored and a clutch (2) that adjusts the length of the lead coming out of the lead tank (1). The present invention has the effect of preventing the lead from getting stuck in the mechanical pencil clutch while writing with a mechanical pencil, making it unusable. In particular, it can prevent the lead from getting caught in the mechanical pencil clutch at important moments while writing, such as a written exam. By adding simple and lightweight parts to an existing mechanical pencil, we provide a mechanical pencil that is not burdensome and can store even more lead by increasing the size of the lead tank.
Description
본 발명은 샤프심이 걸리지 않는 샤프에 관한 것으로, 더욱 상세하게는 샤프 클러치에 샤프심이 걸리지 않아 사용하는 도중 샤프심이 걸리지 않는 샤프에 관한 것이다.The present invention relates to a mechanical pencil in which the lead does not get caught, and more specifically, to a mechanical pencil in which the lead does not get caught during use because the lead does not get caught in the sharp clutch.
일반적으로 샤프로 필기 도중 충격으로 샤프 클러치에 샤프심이 걸려 잘 안빠진다는 문제점을 갖게 되었다.Generally, while writing with a mechanical pencil, an impact causes the lead to become stuck in the mechanical pencil clutch, making it difficult to remove.
특히 필기시험 도중 샤프심이 걸려서 안 빠지면 불이익이 발생할 수 있다.In particular, if the lead gets stuck during the written test and you do not remove it, you may be at a disadvantage.
또한, 샤프심 탱크와 이어져 있는 샤프 클러치는 구멍이 매우 작아 샤프 클러치에 걸린 샤프심을 빼기가 복잡하고 힘들다.Additionally, the hole in the sharp clutch connected to the lead tank is very small, making it complicated and difficult to remove the lead stuck in the sharp clutch.
따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 출원한 것으로서,Therefore, the present invention was applied to solve the above-described conventional problems,
본 발명은 기존에 있던 샤프심 탱크 길이는 늘어나 샤프심을 조금 더 저장할 수 있고 샤프심이 걸리지 않게 하는 샤프 클러치는 길이가 짧아지도록 하는 샤프심이 걸리지 않는 샤프 제공함에 목적이 있다.The purpose of the present invention is to provide a mechanical pencil that does not catch a lead, which can store more lead by increasing the length of the existing lead tank, and shortens the length of the sharp clutch that prevents the lead from getting caught.

본 발명은 샤프로 필기 중 샤프 클러치에 샤프심이 끼어 사용하지 못하는 것을 방지해 주는 효과를 갖고 있다.The present invention has the effect of preventing the lead from getting stuck in the mechanical pencil clutch while writing with a mechanical pencil, making it unusable.
특히 필기시험 등 작성 중 중요한 순간에 샤프 클러치에 샤프심이 끼는 것을 예방할 수 있다.In particular, it can prevent the lead from getting caught in the mechanical pencil clutch at important moments while writing, such as a written exam.
또한, 본 발명은 기존 샤프펜슬에 간단하고 가벼운 부품만 추가해 부담스럽지 않고 샤프심 탱크 크기를 늘려 샤프심을 조금이라도 더 저장할 수 있는 샤프펜슬을 제공한다.In addition, the present invention provides a mechanical pencil that is not burdensome by adding simple and light parts to an existing mechanical pencil, and can store even more pencil leads by increasing the size of the lead tank.

기존에는 샤프 클러치에 샤프심이 걸려 필기 도중 불이익이 생겼다.Previously, the pencil lead got caught in the mechanical pencil clutch, creating a disadvantage while writing.
하지만 본 발명은 기존에 있던 샤프심 탱크 크기를 늘려 샤프심을 조금 더 저장할 수 있으며 샤프 클러치 사이에 샤프심이 끼지 않는다.However, the present invention increases the size of the existing sharp lead tank to store more lead leads, and the lead lead does not get caught between the sharp clutches.
이러한 발명으로 필기시험 등 중요한 순간에서 시험에 집중할 수 있고 샤프 클러치를 플라스틱으로 제작해 더욱더 가볍고 샤프심이 빠르게 나온다.With this invention, you can focus on the exam at important moments such as written exams, and the sharp clutch is made of plastic, making it lighter and the lead comes out faster.
특히 본 발명의 사용 방법은 샤프 노브를 누르면 샤프 안에 내장된 용수철이 눌리면서 샤프 클러치가 열려 샤프심 0.5 MM 정도 나온다. 샤프 부품을 모두 플라스틱으로 만들면 너무 가벼워서 필기가 불편하지 않나 의문이 생기기도 한다.In particular, in the method of using the present invention, when the sharp knob is pressed, the spring built into the sharp is pressed and the sharp clutch opens, releasing about 0.5 MM of the sharp lead. Some people wonder whether if all the mechanical parts were made of plastic, it would be too light and uncomfortable to write with.
아울러 외부 촉을 스테인리스로 제작하여 필기감을 높이며 안정감이 있다.In addition, the outer nib is made of stainless steel, which enhances the writing experience and provides stability.
또한, 샤프 클러치가 샤프심을 잡고 있어 샤프심이 별로 없을 때 다시 안으로 들어가지 않는다. 주변에서 구하기 쉽고 값싼 재료로 제작할 수 있으며 구조가 복잡하지 않아 대량 생산하기 적합하다.Additionally, the sharp clutch holds the sharp lead, so it does not go back in when there is not much lead left. It is easy to find nearby, can be manufactured with inexpensive materials, and has an uncomplicated structure, making it suitable for mass production.
이처럼 상기와 같이 본 발명의 실시한 예에 대하여 상세히 설명하였으나, 본 발명의 권리범위는 이에 한정되지 않으며, 본 발명의 실시한 예와 실질적으로 균등의 범위에 있는 것까지 본 발명의 권리범위가 포함되는 것은 당연하다.Although the embodiments of the present invention have been described in detail as described above, the scope of the rights of the present invention is not limited thereto, and the scope of the rights of the present invention is not limited to the scope of the invention substantially equivalent to the embodiments of the present invention. Of course.
