본 고안은 샤아프펜슬 앞쪽내부에 장착되어 필심에다 소정의 마찰력을 가해주는 필심스톱퍼에 관한 것이다.The present invention relates to a lead stopper which is mounted inside the front of the mechanical pencil to apply a predetermined friction force to the lead.

종래의 필심스톱퍼는 샤아프펜슬의 선단캡내부 또는 선단캡 내부에서 축방향으로 미끄럼왕복이동하는 슬라이더의 내부에 마련된 마찰부여부재로 이루어지고, 이 마찰 부여부재는 앞끝쪽 작은 직경원통부와 뒷끝쪽 큰직경원통부로 된 계단차모양을 한 원통형상으로 일체로 형성되면서 그들 측심부에 필심관통구멍이 뚫려진 구조로 되어 있다.Conventional lead stopper is composed of a frictional imparting member provided in the tip cap of the mechanical pencil or in the slider sliding reciprocally axially in the tip cap. The frictional imparting member is a small diameter cylindrical part at the front end and a rear end part. It is formed in a cylindrical shape with a stepped shape of a large diameter cylindrical part, and a penetrating through-hole is formed in their lateral parts.

그리고 상기 마찰부여부재는 그 작은 직경원통부가 앞쪽으로 향하도록 해서 상기 선단캡이나 상기 슬라이더 속에 압입시켜주며 장착되도록 되어 있는바, 이렇게 장착되게되면 상기 마찰부여부재의 전체외주면이 선단캡 또는 슬라이더의 내부면에 억지맞춤으로 끼워진 상태가 유지되게 된다.In addition, the frictional imparting member is to be pressed into the tip cap or the slider so that the small diameter of the cylindrical portion facing forward, so that the entire outer peripheral surface of the frictional imparting member is inside the tip cap or slider The state of interference fit to the surface is maintained.

이렇게 끼워장착된 상태에서 샤아프펜슬을 녹크조작해서 송출되는 필심이 상기 마찰부여부재의 필심관통구멍에 끼워져 들어가게되면, 이 필심관통구멍의 내주면 부위에서 상기 필심에 소정의 마찰력이 가해지게 되고, 그에따라 필기를 할때 필심이 뒤로밀려나는 것이 방지되게될 뿐만아니라, 필심이 안정되게 지지되어지는 한편 필심의 송출동작도 원활히 이루어지게 되어 있다.When the pen lead, which is sent out by knock operation of the mechanical pencil in the fitted state, is inserted into the pen lead penetrating hole of the friction imparting member, a predetermined friction force is applied to the pen lead at the inner circumferential surface of the pen lead penetrating hole. Accordingly, when writing, the pen core is not only prevented from being pushed back, but also the pen core is stably supported, and the operation of the pen core is smoothly performed.

그런데 이와같이 구성된 종래의 필심스톱퍼는 그 장착상태가 마찰부여부재의 전체 외주면이 선단캡이나 슬라이더의 내주면에 빈틈없이 억지맞춤으로 결합되어져 있기때문에 상기 마찰부여부재가 큰직경방향으로 탄성변형이 이루어질 수가 없어 마찰부여부재나 선단캡 또는 슬라이더등의 중심이 일치되지 못하게되고, 그렇게되면 필심의 중심과 일치되지 못할 경우 이를 흡수할 수 없게된다고 하는 문제가 있었다.However, in the conventional lead stopper configured as described above, since the entire outer circumferential surface of the frictional imparting member is tightly coupled to the inner circumferential surface of the tip cap or slider, the frictional imparting member cannot be elastically deformed in a large diameter direction. There is a problem that the center of the frictional imparting member, the tip cap, or the slider does not coincide, and if it does not coincide with the center of the core, it cannot be absorbed.

즉, 예컨대 필심의 외경이 0.58mm이고, 마찰부여부재의 필심관통구멍 내경과 외경이 각각 0.53mm 1.87mm, 슬라이더의 내경이 1.77mm인 경우, 상기 필심관통구멍에 필심이 끼워넣어질때 상기 마찰부여부재는 상기 필심 직경과의 관계에서 0.05mm가 팽창되게 되고, 상기 슬라이더의 내경과의 관계에서 0.07mm가 팽창됨에 따라 전체적으로 0.12mm가 팽창되게 되는바, 이러한 팽창을 상술한 바와같이 직경방향으로의 탄성변형되지 않는 상기 마찰부여부재로는 흡수할 수가 없기 때문에 필심에 적절한 마찰력을 가할 수가 없게 되고 그로말미암아 필기할때 필심이 뒤로 밀려지는 것이 방지되지 못하게 되므로서 필심의 안정된 지지 및 필심의 송출동작이 원활히 이루어지지 못하게 되는 문제점이 있었다.That is, for example, when the outer diameter of the pen core is 0.58 mm, the inner and outer pen core holes of the frictional imparting member are 0.53 mm 1.87 mm, and the inner diameter of the slider is 1.77 mm, the friction imparting when the pen core is inserted into the pen core penetrating hole. The member is inflated by 0.05 mm in relation to the diameter of the core, and inflated by 0.02 mm in relation to the inner diameter of the slider. As a result, 0.12 mm is inflated. Since the friction imparting member that cannot be elastically deformed cannot absorb the frictional force, it is impossible to apply the frictional force to the core, thereby preventing the core from being pushed backward when writing. There was a problem that can not be made smoothly.

본 고안은 이러한 문제점을 해소해 주기 위해 안출된 것으로, 장착된 상태에서 직경이 큰 방향으로의 탄성변형이 이루어지도록 하므로서 선단캡이나 슬라이더와 필심의 직경이 불일치하게 되는 경우에도 이들을 적절히 흡수 보정해줄 수가 있게됨으로서 필심이 밀려 빠지게되는 현상이 방지되어 필심을 안정되게 지지해줌은 물론 필심의 송출동작이 원활하고 확실하게 이루어지게 하고, 또 조립할때 특정방향을 유지시켜주어야 하는 방향성이 없어지게되며, 조립작업 및 성형작업이 간단해지는 샤아프펜슬의 필심스톱퍼를 제공함에 그 목적이 있다.The present invention was devised to solve such a problem, so that the elastic deformation in the direction of the large diameter is made in the mounted state, so that even if the tip cap or the slider and the diameter of the core are inconsistent, they can be properly absorbed and compensated for. As a result, the pen core is prevented from being pushed out, thereby supporting the pen core stably, as well as smoothly and reliably discharging the pen core, and eliminating the direction of maintaining a specific direction when assembling. And it aims to provide a lead stopper of the mechanical pencil that the molding operation is simple.

이하 본고안의 1실시예를 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제1도에 도시된 바와같이 필심스톱퍼는 공지의 필심스톱퍼와 마찬가지로 고무 또는 합성수지등을 원통형상으로 일체로 성형시킨 마찰부여부재로 되고 있고, 이 마찰부여부재(1)의 외주면 중앙부에는 환형의 오목부(2)가 형성되어 있다.As shown in FIG. 1, the lead stopper is a frictional imparting member formed by integrally molding a rubber or synthetic resin into a cylindrical shape, similarly to the well-known impulsive stopper, and has an annular recess in the center of the outer peripheral surface of the frictional imparting member 1. The part 2 is formed.

또 상기 마찰부여부재(1)의 중심부에는 필심(S)에 소정의 마찰력을 가해주기 위한 필심관통구멍(3)이 형성되고 이 필심관통구멍(3)에는 앞끝쪽을 향해 점차 직경이 켜지는 앞쪽경사구멍부(3a)와 뒷쪽으로 점차 직경이 켜지는 뒷쪽경사구멍부(3b)가 동일축상으로 형성되어져 있다.In addition, the center of the frictional imparting member (1) is formed with a pen core through hole (3) for applying a predetermined friction force to the pen core (S), the front of the pen core through hole (3) is gradually turned toward the front end The inclined hole portion 3a and the rear inclined hole portion 3b whose diameter is gradually turned to the rear side are formed coaxially.

그리고 상기 마찰부여부재(1)는 상기 오목부(2)를 협착해 주게되는 앞뒤끝쪽 외경이 같은 직경으로 되어 축방향에 대한 방향성을 갖지 않는 형상으로 형성되어 있다.In addition, the frictional imparting member 1 is formed in a shape that does not have directionality in the axial direction because the outer diameter of the front and rear ends for squeezing the concave portion 2 is the same diameter.

이와같이 형성된 상기 마찰부여부재(1)는, 상술한 바와같이 방향성이 없기 때문에 간단하게 성형할 수가 있게되고, 또 제3도는 제4도에 도시된 샤아프펜슬의 내부에도 조립하는 것도 간단히 이루어지게 되는 것이다.The frictional imparting member 1 formed in this way can be formed simply because there is no directivity as described above, and FIG. 3 is also easily assembled inside the mechanical pencil shown in FIG. will be.

이러한 조립은 제3도는 제4도에 도시된 샤아프펜슬의 선단캡(5)내에다 마찰부여부재(1)를 압입시켜주고, 제4도의 경우에 있어서는 상기 선단캡(5)내에서 축방향으로 이동할 수 있도록 된 슬라이더(6) 내에다 상기 마찰부여부재(1)를 압입시켜줌으로서 조립이 이루어지게 된다.This assembly presses the friction imparting member 1 into the tip cap 5 of the mechanical pencil shown in FIG. 4, and in the case of FIG. 4 in the axial direction in the tip cap 5. The assembly is achieved by pressing the frictional imparting member 1 into the slider 6 which can be moved to.

이와같은 조립상태에서 산기 마찰부여부재(1)는 그 오목부(2)를 제외한 앞뒤부위 외주면이 제3도의 경우에는 선단캡(5) 내주면에, 또 제4도의 경우에는 슬라이더(6)의 내주면에 각각 억지맞춤으로 간격없이 걸어맞춰진 상태를 유지하게 될뿐만아니라, 그 어느경우에도 상기 선단캡(5) 또는 슬라이더(6)의 내주면과 상기 오목부(2) 사이에 환형의 공간부가 형성되게 된다.In such an assembled state, the diffuser friction imparting member 1 has an outer circumferential surface of the front and rear portions excluding the recess 2 on the inner circumferential surface of the tip cap 5 in the case of FIG. 3, and the inner circumferential surface of the slider 6 in the case of FIG. In addition to maintaining the state of being engaged with each other at intervals without interference, in any case, an annular space is formed between the inner circumferential surface of the tip cap 5 or the slider 6 and the concave portion 2. .

그리고 상기와 같이 조립된 상태에서의 마찰부여부재(1)는, 그 오목부(2)에 의해 직경이 큰방향으로 탄성적으로 변형될 수 있게되어, 상기 선단캡(5)이나 슬라이더(6)가 축방향 또는 직경방향으로 어긋나게 되거나, 필심의 직경방향으로의 불균형, 마찰부여부재(1) 자체가 직경방향으로부터 어긋나 마찰부여부재(1)의 필심관통구멍(3)에 필심(S)이 끼워넣어질때 발생하게 되는 상기 마찰부여부재(1)의 팽창이 상기 오목부(2)의 큰직경 방향으로 탄성적으로 변형됨에 따라 흡수되어지게 된다.In addition, the frictional imparting member 1 in the assembled state as described above can be elastically deformed in a large direction by the concave portion 2, so that the tip cap 5 or the slider 6 The core S is deviated in the axial direction or the radial direction, or the unevenness of the core in the radial direction, the frictional imparting member 1 itself is shifted from the radial direction, and the core C is inserted into the penetrating through hole 3 of the frictional imparting member 1. The expansion of the frictional imparting member 1, which is generated when it is inserted, is absorbed as it is elastically deformed in the large diameter direction of the recess 2.

이와같이 상기 필심스톱퍼의 오목부(2)가 상기 불균형을 흡수해주게됨에 따라, 특히 본고안출원인이 기히 출원한 바있는 1986년 특허출원 제3426호인 자동샤아프펜슬의 슬라이더에다 적용하게 되면 더 큰 효과를 얻을 수 있게 된다.As the concave portion 2 of the lead stopper absorbs the imbalance, it is particularly effective when applied to the slider of the automatic mechanical pencil of patent application No. 3426 1986, which has been filed by the applicant. You can get it.

즉, 상기 선출원한 바있는 샤아프펜슬에서는 지면등으로부터 슬라이더의 필기압을 해제시켜주면 필심이 자동적으로 송출되게 되는바, 이와같이 필기압을 해제시켜 필심송출이 자동적으로 이루어지도록 하기위해 필심을 물어잡는 리이드척이 필심이 전진은 쉽게 허용하지만 후퇴는 저지하는 구조로 되어있어, 필심이 전진할 때와 후퇴할때에는 필심에 대한 마찰부여부재의 마찰력이 다르기 때문에 필심에 대한 마찰부여부재로서 상기 필심스톱퍼를 사용하게 되면 필심송출을 원활하고 확실하게 수행되도록 해줄 수가 있게된다.In other words, in the pencil pencil that has been previously filed, the pen core is automatically sent out by releasing the writing pressure of the slider from the ground, and so on. The lead chuck has a structure that allows the lead to move forward but prevents the retraction, and the friction stopper for the lead is different when the lead moves forward and retracts. When used, it will be possible to ensure that the delivery of the sentiments is performed smoothly and reliably.

이상의 설명에서와 같이 본고안에 의하면 샤아프펜슬이 송출되어 나온 필심에 소정의 마찰력을 부여해주기 위한 필심스톱퍼가 그 전체길이에 걸쳐 같은 외경을 갖는 원통형으로 형성되면서 그 필심스톱퍼의 외주면 중앙부에 오목부가 형성되어져 있기 때문에 이러한 필심스톱퍼가 장착되는 샤아프펜슬의 선단캡 또는 슬라이더의 축방향이나 직경방향으로의 불일치 또는 상기 필심스톱퍼 자체의 불일치등을 상기 오목부가 흡수해줄 수가 있고, 또 상기 필심스톱퍼는 방향성을 갖지 않기 때문에 성형 및 조립이 간단히 이루어지게 되는 효과가 있다.As described above, according to the present proposal, a pen stopper for imparting a predetermined frictional force to the pen core from which the pencil is sent out is formed into a cylindrical shape having the same outer diameter over its entire length, and a recess is formed in the center of the outer peripheral surface of the pen stopper. Since the tip cap or slider of the mechanical pencil on which the lead stopper is mounted is inconsistent in the axial or radial direction, or the discrepancy of the lead stopper itself, the recess can absorb the directional stopper. Since it does not have the effect that the molding and assembly is made simply.
