색연필의 필심 결합구조{A lead coupling structure of colored pencil}A lead coupling structure of colored pencil

본 발명은 색연필의 필심 결합구조에 관한 것으로서, 더욱 상세하게는 색연필의 필심 결합구조에 있어서, 출몰이송구와 결합되는 필심의 결합부에 결합 완충부를 형성하여서, 색연핀의 필심과 출몰 이송구를 억찌 끼움 결합함에 있어 출몰이송구의 탄성변형 및 결합부의 압축 변형을 유도하여 결합이 용이하게 이루어질 수 있도록 함을 목적으로 한 것이다.
The present invention relates to a pen core coupling structure of colored pencils, and more particularly, in a pen core coupling structure of colored pencils, by forming a coupling buffer portion at a coupling portion of a pen core coupled with a projection port, In the interlocking fitting, it is intended to facilitate the coupling by inducing the elastic deformation of the inlet port and the compression deformation of the coupling portion.

일반적으로, 색연필은 다양한 색상을 가진 필심으로 이루어진 필기구의 하나이다.In general, colored pencils are one of writing instruments made of a lead with a variety of colors.

이상과 같은 색연필은 필심에 종이 밴드를 원통형으로 감아 필요시마다 정해진 길이 단위로 인출되도록 한 종이 몸체 색연필과, 필심의 둘레에 원형 또는 다각형 단면의 나무 소재를 접합하여 몸통을 형성한 나무 몸체 색연필과, 필심을 출몰수단에 의하여 출몰되게 구성된 회전 출몰형 색연필이 개발되어 사용되고 있다.
The colored pencils described above include a paper body colored pencil wound around a paper band in a cylindrical shape and drawn out in a predetermined length unit whenever necessary, and a wooden body colored pencil formed by joining a wooden material of circular or polygonal cross section around the core to form a trunk. Rotating colored pencils have been developed and used to be penetrated by the pen the pens.

여기서, 상기 회전 출몰형 색연필은 내부에 필심의 수용공간을 갖는 관체로 이루어진 몸체와, 상기 몸체에 수용된 필심의 후단 결합부와 결합되어 상기 필심을 출몰 이송시키는 출몰 이송구와, 상기 출몰 이송구를 이송시키는 출몰이송수단 및 상기 출몰이송수단을 회전동작시킬 수 있게 몸체의 후단에 결합되는 회전손잡이로 구성한 것이다.
Here, the rotatable colored pencil has a body made of a tubular body having a space of the pen core therein, a haul conveying port coupled to the rear end coupling portion of the pen core accommodated in the body and conveys the pen core and the haul conveying port It is composed of the rotatable transport means to be coupled to the rear end of the body so that the rotatable transport means and the rotatable transport means to rotate.

상기 출몰이송수단은 출몰 이송구를 나선 결합하며 회전손잡이에 결합되어 회전손잡이의 회전에 따라 출몰 이송구를 몸체의 내벽을 따라 수평 이동시키는 출몰스프링으로 구성한 것과, 몸체의 내벽에 출몰 나선홈을 형성하고, 회전손잡이와 결속되며 출몰 이송구의 일측 이상의 측면을 지지하여 상기 출몰 이송구가 출몰 나선홈을 따라 회전 이송되게 하는 출몰 이송바로 구성한 것이 개발되어 사용되고 있다.The wandering conveying means is a spiral coupling of the spouting conveyance port and is coupled to the rotary knob consisting of a spout spring for horizontally moving the wandering transfer port along the inner wall of the body in accordance with the rotation of the rotary knob, forming a spiraling groove on the inner wall of the body In addition, it has been developed and used that is configured with a lifting handle bar that is coupled to the rotation handle and supporting the side of the one side of the haul conveying port so that the hauling conveyer is rotated along the hauling spiral groove.

한편, 상기한 바와 같은 회전 출몰형 색연필에 있어서, 필심과 출몰 이송구의 결합구조는 출몰 이송구의 전단에 결합관체를 형성하고, 필심의 후단에 상기 결합관체에 억지 끼움 결합되게 단차 가공된 결합부를 형성하여서, 상기 필심의 결합부를 출몰 이송구의 결합관체에 억찌 끼움 결합하는 것이다.On the other hand, in the above-mentioned rotating appearance type colored pencil, the coupling structure of the pen core and the haul conveying port is formed in the front end of the haul conveying port, the coupling end is formed in the rear end of the core to form a coupling process stepped to fit the coupling tube By doing so, the coupling portion of the core is interfitted and coupled to the coupling tube of the delivery port.

상기 필심의 결합부에는 출몰 이송구의 결합관체와의 용이한 결합을 위하여 결합테이퍼부를 형성하여 필심의 결합부가 출몰 이송구의 결합관체에 용이하게 결합되게 구성한 것이다.The coupling portion of the pen core is configured to form a coupling taper for easy coupling with the coupling tube of the haul conveyance port is configured to be easily coupled to the coupling tube of the haul transfer port.

그러나, 상기한 바와 같은 종래 색연필은 필심과 출몰 이송구의 결합이 출몰이송구의 결합관체에 원 봉상으로 이루어진 필심의 결합부를 억지 끼움 결합하게 구성되어 있어 그 결합에 일정한 힘을 가하여야 하는데 억지 끼움시 출몰 이송구에 필심 결합부가 잘 들어가지 않아 조립된 필심의 전체 길이가 작업자에 따라 다르게 되어 조립 완성된 색연필의 최초 필심 돌출량이 상이하게 되고, 억지 끼움시 그 결합량이 적게 되면 필심의 출몰과정에 있어 필심이 색연필로부터 이탈되는 문제점이 있었다.However, in the conventional colored pencil as described above, the combination of the pen core and the inlet transport port is configured to force the coupling part of the pen core made of a round rod into the coupling tube of the inlet transport port, so that a constant force must be applied to the coupling. Since the combined length of the core is not easily entered in the hauling port, the total length of the assembled core differs depending on the worker, so the initial amount of protrusion of the assembled colored pencil is different. There was a problem that the lead is separated from the colored pencils.

또한, 필심과 출몰 이송구의 억지 끼움 작업시 과도한 힘을 주게 되면 결합력으로 인하여 연질의 필심이 절단 손상되는 문제점이 있었다.
In addition, there is a problem in that the soft pen core is cut and damaged due to the coupling force when excessive force is applied during the interference operation of the pen core and the hauling transfer port.

이에, 본 발명은 상술한 바와 같이 종래의 색연필은 필심과 출몰 이송구의 결합이 억지 끼움 결합에 의하여 이루어져 그 결합과정에 있어 필심에 과도한 힘이 작용되어 절단 손상되는 등 그 결합이 용이하지 않은 문제점이 있었다.Thus, the present invention, as described above, the conventional colored pencil is made by the coupling of the pen core and the hauling transfer port is made by the force of the coupling coupling is not easy to combine such that the excessive force is applied to the core in the process of cutting, such as cutting damage there was.

즉, 본 발명은 색연필의 필심 결합구조에 있어서, 출몰 이송구의 결합관체와 결합되는 필심의 결합부 측면에 결합 완충부를 형성한 것이다.That is, the present invention is to form a coupling buffer portion on the side of the coupling portion of the pen core coupled to the coupling tube of the delivery port in the pen core coupling structure of the colored pencil.

따라서, 본 발명은 필심의 결합부 측면에 결합 완충부를 형성함으로써 필심의 결합부를 출몰 이송구의 결합관체에 결합함에 있어서, 결합부의 결합 완충부에 대응되는 출몰 이송구의 결합관체가 중심부로 수축변형되고 다른 부분은 확장변형되어 그 결합이 부드럽게 이루어지는 것이다.Accordingly, in the present invention, when the coupling portion of the core is coupled to the coupling tube of the inlet transport port by forming the coupling buffer portion on the side of the coupling portion of the core, the coupling tube of the inlet transport port corresponding to the coupling buffer of the coupling unit is deformed to the center and is different. The part is expanded and the coupling is smooth.

이하, 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

본 발명은 색연필의 필심과 출몰 이송구의 결합이 용이하고 견고하게 이루어지도록 한 것이다.The present invention is to be made easily and firmly combined with the pen lead of the colored pencil and the hauling transport.

즉, 본 발명은 내부에 필심(100)의 수용공간을 갖는 관체로 이루어진 몸체(300)와, 상기 몸체에 수용된 필심(100)의 후단에 형성되며 단부에 결합테이퍼부(111)가 형성된 결합부(110)와 결합되어 상기 필심(100)을 출몰 이송시키는 출몰 이송구(210)와, 상기 출몰 이송구(210)를 이송시키는 출몰이송수단 및 상기 출몰이송수단을 회전 동작시킬 수 있게 몸체(300)의 후단에 결합되는 회전손잡이(220)로 이루어진 색연필의 필심 결합구조에 있어서, 출몰 이송구(210)의 결합관체(211)와 결합되는 필심(100)의 결합부 측면에 하나 이상의 결합 완충부(1)를 형성한 것이다.That is, the present invention is formed at the rear end of the body 300 made of a tubular body having a receiving space of the pen core 100 therein, and the pen core 100 accommodated in the body and the coupling taper portion 111 is formed at the end Combined with the 110, the hauling conveyance port 210 for hauling and conveying the pen core 100, the hauling conveying means for conveying the hauling conveying port 210 and the body to be rotatable operation of the hauling conveying means In the lead coupling structure of the colored pencil made of a rotary handle 220 is coupled to the rear end of the), one or more coupling buffer portion on the side of the coupling portion of the pen core 100 is coupled to the coupling tube 211 of the hauling port 210 (1) was formed.

여기서, 상기 결합 완충부(1)는 봉 형상으로 이루어진 필심 결합부(110)의 측면을 절삭하여 평면과 돌출곡면 및 요입곡면 중 어느 하나의 면으로 절삭 형성한 것이다.Here, the coupling buffer 1 is formed by cutting the side surface of the core coupling portion 110 having a rod shape to any one of a plane, a protruding curved surface and a concave curved surface.

상기 결합 완충부(1)는 1 개 내지 5 개로 형성하여 실시함이 바람직한 것으로서, 5 개 이상으로 형성하게 되면 출몰 이송구(210)의 결합관체(211) 내벽과 접촉되는 결합부(110)의 면적이 적어져 필심(100)이 결합관체(211)에 결합상태에서 쉽게 회전 및 이탈되는 문제점이 있으므로 5 개 이내로 실시함이 바람직한 것이다.
The coupling buffer 1 is preferably formed by forming one to five, if formed in five or more of the coupling portion 110 in contact with the inner wall of the coupling tube 211 of the delivery port 210, Since the area is reduced, there is a problem that the core 100 is easily rotated and detached from the coupled body 211 in a coupled state, and therefore, it is preferable to carry out within five.

이하, 본 발명에 따른 필심과 출몰 이송구의 결합과정에 대하여 설명하면 다음과 같다.Hereinafter, a description will be given of the coupling process between the lead and the haul conveying port according to the present invention.

상기한 바와 같이 색연필의 필심 결합구조에 있어서, 출몰 이송구(210)의 결합관체와 결합되는 필심(100)의 결합부(110) 측면에 하나 이상의 결합 완충부(1)를 형성한 본 발명이 적용된 필심(100)을 출몰 이송구(210)에 조립하게 되면, 상기 필심(100)의 결합부(110)가 출몰 이송구(210)의 결합관체(211)에 결합되는 과정에 있어 결합부(110)의 단부에 형성한 결합테이퍼부(111)로 인하여 초기 결합이 부드럽게 이루어지는 것이다.As described above, in the pen core coupling structure of the colored pencil, the present invention in which at least one coupling buffer unit 1 is formed on the side of the coupling unit 110 of the pen core 100 coupled to the coupling tube of the outgoing transfer port 210 is provided. When the applied lead core 100 is assembled to the hauling port 210, the coupling part 110 in the process of coupling the coupling portion 110 of the pen core 100 to the coupling tube 211 of the hauling port 210 ( Due to the coupling taper 111 formed at the end of the 110 is the initial coupling is made smoothly.

이상과 같이 필심(100)의 결합부(110)가 출몰 이송구(210)의 결합관체(211)에 초기 결합이 결합테이퍼부(111)를 통하여 이루어지는 것이다.As described above, the coupling portion 110 of the lead core 100 is initially coupled to the coupling tube 211 of the delivery port 210 through the coupling taper 111.

그리고, 상기 결합테이퍼부(111)에 의한 초기 결합이 이루어진 결합부(110)가 계속하여 결합관체(211)에 삽입되게 되면 결합부(110)가 결합관체(211)에 억지 끼움 결합이 이루어지게 되는데 이때 결합 완충부(1)와 대응되는 결합관체(211)가 중심을 향하여 수축 변형이 되게 되고, 결합관체(211)의 다른 부분은 상대적으로 중심의 바깥 측으로 변형이 이루어져 필심(100)의 결합부(110)가 부드럽게 결합이 이루어지는 것이다.
이와 같이, 상기 결합관체(211)는 결합부(110)에 결합될 때 결합부(110)의 측면을 절삭하여 평면과 돌출곡면 및 요입곡면을 따라 수축 및 팽창 변형이 이루어지도록 신축성을 갖도록 형성되어 억지끼움 되나 필심(100)의 결합부(110)에 강한 압박감을 주지않도록 되는 것이다.Then, when the coupling portion 110, the initial coupling by the coupling taper portion 111 is continuously inserted into the coupling tube 211, the coupling portion 110 is forcibly fitted to the coupling tube 211 is made. In this case, the coupling buffer unit 1 and the coupling tube 211 corresponding to the shrinkage deformation toward the center, the other portion of the coupling tube 211 is relatively deformed toward the outer side of the center of the coupling 100 The unit 110 is a soft coupling is made.
As such, when the coupling tube 211 is coupled to the coupling unit 110, the coupling tube 211 is formed to have elasticity such that the side surface of the coupling unit 110 is cut and contracted and expanded along the plane, the protruding curved surface, and the concave curved surface. Being forced but will not give a strong pressure to the coupling portion 110 of the core (100).

이때, 연질로 이루어진 필심(100)의 결합부(110) 중 결합관체(211)와 긴밀하게 결속되는 부분은 결합관체(211)의 내벽과 접촉에 있어 결합관체(211)의 신축성에 의해 미세한 압축변형이 이루어지는 것이다.At this time, the portion of the coupling portion 110 of the soft core 100 is tightly coupled with the coupling tube 211 is in contact with the inner wall of the coupling tube 211, the fine compression by the elasticity of the coupling tube 211 The transformation is made.

상기한 바와 같은 과정을 통하여 결합된 필심(100)은 출몰 이송구(210)가 대응되는 결합관체(211)가 중심으로 향한 수축변형을 통하여 형성된 결합 완충부(1) 양측 경계부에서의 곡률 변화로 인하여 회전이 제한되어 필심(100)이 회전되지 않고 견고한 결속이 이루어지는 것이다.
The pen core 100 coupled through the process as described above is a change in curvature at both sides of the coupling buffer 1 formed through shrinkage deformation toward the center of the coupling tube 211 corresponding to the inlet and outlet 210. Due to the rotation is limited, the solid core 100 is not rotated and a solid binding is made.

따라서, 본 발명은 필심의 결합부 측면에 결합 완충부를 형성함으로써 필심의 결합부를 출몰 이송구의 결합관체에 결합함에 있어서, 결합부의 결합 완충부에 대응되는 출몰 이송구의 결합관체가 중심부로 수축변형되고 다른 부분은 확장변형되어 그 결합이 부드럽게 이루어지는 것이다.Accordingly, in the present invention, when the coupling portion of the core is coupled to the coupling tube of the inlet transport port by forming the coupling buffer portion on the side of the coupling portion of the core, the coupling tube of the inlet transport port corresponding to the coupling buffer of the coupling unit is deformed to the center and is different. The part is expanded and the coupling is smooth.

이상과 같이 필심과 출몰 이송구의 결합이 부드럽게 이루어져 필심의 전체 길이가 항상 동일하게 되어 조립 완료된 색연필의 최초 필심 돌출량이 균일하게 유지되는 것이다.As described above, the combination of the pen core and the hauling transfer port is smooth, so that the total length of the pen core is always the same, so that the first pendulum protrusion amount of the assembled colored pencil is maintained uniformly.
