본 고안은 볼펜이나 수성잉크펜, 만년필등과 같은 필기구에 관한 것으로, 특히 캡(cap)이 없는 필기구에 관한 것이다.The present invention relates to a writing instrument such as a ballpoint pen, an aqueous ink pen, a fountain pen, and the like, and more particularly, to a writing instrument without a cap.
종래에도 캡없는 필기구로서 제4도 및 제5도에 도시된 것과 같은 것이 있었던바, 이들 도면중 제4도는 종래의 캡없는 필기구를 펜선단부가 수납된 상태로 도시된 단면이고, 제5도는 펜선단부가 돌출된 상태를 도시한 단면도인데, 여기서 도면부호 1은 외통이고, 2는 외통(1)내에 끼워지는 필기축체이며, 4a,4b는 필기축체(2)의 선단부를 그 간격(3)사이에 넣어 덮어 씌워주면서 축방향을 따라 2개로 갈라진 한쪽끝이 폐쇄되어지는 내통부이다. 한편 부호 5는 필기축체(2)의 후단에 설치된 노크부이고, 6은 필기축체(2)에 설치된 스프링받침(8)과 양쪽이 분할내통부(4a,4b)의 후단날개부(9)사이에 설치된 압축스프링이며, 10은 양 날개부(9)의 지지점으로서 스프링축과 반대편 외통(1)부분에 형성되어 있다.Conventionally, there is a capless writing instrument such as those shown in FIGS. 4 and 5, and FIG. 4 is a cross-sectional view of a conventional capless writing instrument with a pen tip stored therein, and FIG. It is sectional drawing which shows the state which protruded the tip part, where 1 is an outer cylinder, 2 is a writing shaft body inserted in the outer cylinder 1, and 4a, 4b is a front end part of the writing shaft body 2 between the spaces 3. It is an inner cylinder part that is closed in two parts along the axial direction while covering it. On the other hand, reference numeral 5 denotes a knock portion provided at the rear end of the writing shaft body 2, and 6 denotes a spring bearing 8 provided at the writing shaft body 2 and between the rear wing portions 9 of the split inner cylinder portions 4a and 4b. It is a compression spring installed in, and 10 is formed in the outer cylinder 1 part opposite to a spring shaft as a support point of both wing parts 9.
이와 같은 종래의 캡없는 필기구에는 필기축체(2)의 노크부(5)를 압축스프링(6)에 대항해 눌러주게 되면 분할내통부(4a,4b)가 필기축체(2) 선단부의 경사면(11)에 의해 눌려져 열려져서 필기축체(2)의 펜끝(2a)이 분할내통부(4a,4b)로부터 빠져나와 외통(1)의 선단밖으로 돌출하게 되고, 그 상태에서 회전캠기구(도시안됨)에 의해 지지되어져서 필기축체(2)의 펜끝(2a)으로 필기를 할 수가 있게 된다. 이어 다시 노크부(5)를 눌러주게 되면 회전캠 기구에 의한 지지상태가 풀려 압축스프링(6)의 탄발력에 의해 필기축체(2)가 제자리로 돌아온 상태에서 분할내통부(4a,4b)가 그후단 날개부(9)를 압접하게 되는 지지점(10)을 중심으로 회동하여 닫히게 된다.In such a conventional capless writing implement, when the knock portion 5 of the writing shaft 2 is pressed against the compression spring 6, the divided inner cylinder portions 4a and 4b are inclined surfaces 11 of the tip of the writing shaft 2. The pen tip 2a of the writing shaft 2 is pushed out and is released from the divided inner cylinder portions 4a and 4b so as to protrude out the tip of the outer cylinder 1, and in this state by the rotating cam mechanism (not shown). It is supported so that writing can be performed with the pen tip 2a of the writing shaft 2. Subsequently, when the knocking portion 5 is pressed again, the supporting state of the rotating cam mechanism is released, and the split inner cylinder portions 4a and 4b are released when the writing shaft 2 is returned to its original position by the elastic force of the compression spring 6. After that, the end wing 9 is rotated about the support point 10 to be pressed to close.
그러나 상기와 같은 종래의 캡없는 필기구는 분할내통부(4a,4b)가 열려져 있을때 필기축체(2)의 펜끝(2a)부분이 외통(1)의 선단구에 지지되어져 있게 되기 때문에 페끝(2a)부분과 선단구 사이에 틈새가 나서 필기를 할때 펜끝이 흔들려 필기하기 곤란할 뿐만 아니라, 양쪽 분할내통부(4a,4b)가 그 후단날개부(9)를 압축스프링(6)으로 압접시켜주는 지지점(10)을 중심으로 회동시켜 개폐시켜주도록된 구조로 구성되어 있기 때문에 내통(4)을 안정되게 지지해줄 수가 없다고 하는 문제점이 있었다.However, the conventional capless writing implement as described above has the pen tip 2a because the pen tip 2a portion of the writing shaft 2 is supported by the tip end of the outer cylinder 1 when the divided inner cylinder portions 4a and 4b are opened. Supporting point that the pen tip is shaken and difficult to write when writing because there is a gap between the part and the tip, and both inner cylinder parts 4a and 4b press-fit the rear wing part 9 with the compression spring 6. There is a problem that the inner cylinder (4) can not be stably supported because it is composed of a structure that rotates about (10) to open and close.
이에 본 고안의 캡없는 필기구는, 상기와 같은 문제점을 해결해 주기 위하여, 제1도 및 제2도에 도시된 바와 같이 외통(1)내에 필기축체(2)가 끼워넣어지면서 이 필기축체(2)의 선단부를 그 사이 간격(3)안에다 씌워넣으면서 그 한쪽끝을 개폐시켜줄 수 있도록된 내통(4)을 설치한 다음 필기축체(2)의 노크부(5)를 압축스프링(6)에 대항하여 눌러주거나 또는 눌러진 스프링의 탄발력으로 되돌려지게 됨에 따라 그 한쪽끝이 내통(4)을 개폐시켜 필기축체(2)의 펜끝(2a)을 상기 내통(4)으로부터 출몰시켜줄 수 있도록한 캡없는 필기구에 있어서, 상기 한쪽끝을 개폐할 수 있도록된 내통(4)을 개폐되어지는 단부가 외통(1)의 선단부(1a)내면과 닿게되는 탄성접편(12a,12b)을 갖는 탄성체로 만들어 이 내통(4)의 후단 날개부(9)를 외통(1)의 선단부(1a)내주면에 걸려지도록 구성시켜 놓은 것이다.Accordingly, the capless writing instrument of the present invention, in order to solve the above problems, the writing shaft body 2 is inserted into the outer cylinder 1 as shown in FIGS. 1 and 2. The inner cylinder 4 is provided to open and close one end while covering the distal end portion of the distal end portion 3, and then the knock portion 5 of the writing shaft 2 against the compression spring 6 A capless writing instrument that allows one end to open and close the inner cylinder 4 as it is returned to the elastic force of the pressed or pressed spring, thereby allowing the pen tip 2a of the writing shaft 2 to emerge from the inner cylinder 4. In the inner cylinder (4) to open and close the one end is made of an elastic body having an elastic contact piece (12a, 12b) in which the open end is in contact with the inner surface of the front end portion (1a) of the outer cylinder (1) The rear wing 9 of 4) is configured to be hooked to the inner circumferential surface of the front end 1a of the outer cylinder 1.

제1도 및 제2도에서 부호 1은 외통이고, 2는 이 외통(1)내에 끼워넣어진 필기축체, 4a,4b는 이 필기축체(2)의 선단부를 간격(3)사이에 넣어 덮어씌워 주도록 탄성체로 만들어져 그 한쪽끝이 폐쇄되는 형식의 내통(4)을 형성하게 되는 축방향을 따라 2개로 갈라진 분할내통부이다.In FIG. 1 and FIG. 2, the code | symbol 1 is an outer cylinder, 2 is a writing shaft body inserted in this outer cylinder 1, and 4a, 4b cover the front-end | tip part of this writing shaft body 2 between the space | intervals 3, and are covered. The split inner cylinder portion is divided into two along the axial direction, which is made of an elastic body and forms an inner cylinder 4 in which one end thereof is closed.
이 양쪽 분할내통부(4a,4b)의 폐쇄단에는 외통(1)의 선단부(1a)내면에 닿는 혀모양을 갖는 탄성접편(12a,12b)이 갖추어져 있다(제3도 (a),(b),(c)참조).At the closed end of both divided inner cylinder parts 4a and 4b, the elastic contact pieces 12a and 12b which have the tongue shape which touches the inner surface of the front end part 1a of the outer cylinder 1 are provided (FIG. 3 (a), (b). ), (c)).
또 상기 분할내통부(4a,4b)의 후단날개부(9)는 외통(1)의 선단부(1a)내주에 형성시킨 계단부에 걸려끼워져 있다.Moreover, the trailing blade part 9 of the said division inner cylinder part 4a, 4b is caught by the step part formed in the inner periphery of the tip part 1a of the outer cylinder 1. As shown in FIG.
본 실시예에서는 양쪽 분할내통부(4a,4b)의 후단부(13)를 일체로 연결시켜 놓은 구조로 되어 있지만 분리시킨 구조로 해도 좋다.In this embodiment, the rear end portion 13 of both the split inner cylinder portions 4a and 4b is integrally connected to each other, but may be separated.
본 실시예의 분할내통부(4a,4b)는 원뿔대형상의 공간(3a)을 형성하는 테이퍼부(14)(제3도 (c) 참조)이외에 원통형 공간(3b)을 형성하는 평행부(15)(제3도 (b) 참조)를 형성시켜 놓고 있지만 이 평행부(15)을 설치하지 않아도 좋다.The divisional inner cylinder portions 4a and 4b of the present embodiment have parallel portions 15 which form a cylindrical space 3b in addition to the tapered portion 14 (see FIG. 3 (c)) forming the conical shaped space 3a. (See FIG. 3 (b)), the parallel portion 15 may not be provided.
한편 부호 5는 필기축체(2)의 후단에 설치된 노크부이고, 8은 필기축체(2)에 설치된 스프링 받침, 6은 이 스프링받침(8)과 분할내통부(4a,4b)의 후단부(13)사이에 설치된 압축스프링으로서, 필기축체(2)의 노크부(5)를 압축스프링(6)에 대항해서 눌러주게 되면 분할내통부(4a,4b)의 원뿔대형 공간(3a)을 형성하는 테이퍼부(14)의 내면에 필기축체(2)의 선단부가 경사면(11)이 닿아 그를 밀어붙여주게 되어 이 경사면(11)이 밀어붙여주는 힘으로 외통(1)의 선단부(1a)내면에 닿아있는 폐쇄단부의 탄성접편(12a,12b)이 굽혀짐과 더불어 양쪽의 분할내통부(4a,4b)가 바깥쪽으로 구부러지면서 벌려져 필기축체(2)의 펜끝(2a)이 분할내통부(4a,4b)로 부터 돌출되어져 나오게 되고(제2도 참조), 이런 상태에서 회전캠기구(도시안됨)에 의해 지지되어져서 필기축체(2)의 펜끝(2a)으로 필기를 할수가 있게되는 것이다.On the other hand, reference numeral 5 denotes a knock portion provided at the rear end of the writing shaft body 2, 8 denotes a spring bearing provided on the writing shaft body 2, and 6 denotes a rear end portion of the spring bearing 8 and the divided inner cylinder portions 4a and 4b ( 13 is a compression spring provided between the taper forming the conical cylindrical space 3a of the inner cylinder portion 4a, 4b when the knocking portion 5 of the writing shaft 2 is pressed against the compression spring 6. The tip of the writing shaft 2 touches the inclined surface 11 on the inner surface of the portion 14 so as to push it against the inner surface of the writing cylinder 2, and the inclined surface 11 is pressed against the inner surface of the tip 1a of the outer cylinder 1 by the pushing force. As the elastic contact pieces 12a and 12b of the closed end are bent, both divided inner cylinder portions 4a and 4b are bent outwardly to open, and the pen tip 2a of the writing shaft 2 is divided into the inner cylindrical portions 4a and 4b. Protrudes from () and is supported by a rotating cam mechanism (not shown) in this state to write with the pen tip 2a of the writing shaft 2. You will be able to.
한편 분할내통부(4a,4b)가 열려진 상태에 있을 때에는 필기축체(2)의 펜끝(2a)부분이 양쪽으로 갈라진 분할내통부(4a,4b)의 탄성복원력과 외통(1)의 선단부(1a)내면에 닿아있는 탄성접편(12a,12b)의 탄성복원력에 의해 양쪽 분할내통부(4a,4b)의 폐쇄단부 사이에 압접지지되어지기 때문에 펜끝(2a)부분과 외통(1)의 선단부와의 사이에 틈새가 있게 되더라도 필기할때 흔들리게 되는 일이 없다.On the other hand, when the divided inner cylinder portions 4a and 4b are in the open state, the elastic restoring force of the divided inner cylinder portions 4a and 4b where the pen tip 2a portion of the writing shaft 2 is divided into both sides and the tip portion 1a of the outer cylinder 1 Since the elastic contact force of the elastic contact pieces 12a and 12b touching the inner surface is pressed against the closed ends of the two inner cylinder parts 4a and 4b, the tip of the pen tip 2a and the outer end of the outer cylinder 1 Even if there is a gap in between, you won't be shaken when writing.
이어 다시한번 노크부(5)를 눌러주면 회전캠기구에 의한 지지상태가 풀려져서 압축스프링(6)의 탄발력에 의해 필기축체(2)가 되돌려짐과 더불어 양 분할내통부(4a,4b)와 그 폐쇄단부의 탄성접편(12a,12b)이 그들 자체의 탄성복력으로 제1도의 상태로 되돌려져서 양 분할내통부(4a,4b)가 닫혀지게 된다.Then, once the knock portion 5 is pressed again, the state of support by the rotary cam mechanism is released, and the writing shaft 2 is returned by the elastic force of the compression spring 6, and both the split inner cylinder portions 4a and 4b. And the elastic contact pieces 12a and 12b at the closed end thereof are returned to the state of FIG. 1 by their elastic resilience, so that the two inner cylinder parts 4a and 4b are closed.
본 고안에서는 양 분할내통부(4a,4b)의 후단부(13)(개방측) 내주면에 탄성씨일부(7)를 설치해 놓아도 좋은데, 이와 같이 구성시켜 놓는 경우에는 양쪽 분할내통부(4a,4b)가 폐쇄상태에 있을때 양자의 접면사이는 양 내통부(4a, 4b)를 탄성체로 형성시켜 놓고 있기 때문에 종래의 비탄성체로 된 것보다 밀폐성이 향상된다는 점과 양 내통부(4a,4b)의 개방측이 탄성씨일부(7)에 의해 밀폐됨에 따라 필기축체(2)의 선단부를 그 간격(3)사이에 넣어 덮어씌우는 분할내통부(4a,4b)내부를 밀폐시켜 줄 수가 있기 때문에 필기축체(2)의 펜끝(2a)으로부터 잉크가 증발되는 증발량을 억제시켜줄 수가 있고 또 먼지가 침입하는 것을 막아줄 수가 있다.In the present invention, the elastic seal portion 7 may be provided on the inner circumferential surface of the rear end portion 13 (open side) of the two inner cylinder portions 4a and 4b. In this case, the two inner cylinder portions 4a and 4b are provided. ) In the closed state, both inner cylinder portions 4a and 4b are formed of an elastic body, so that the sealing property is improved compared to that of the conventional inelastic materials, and the opening of both inner cylinder portions 4a and 4b. As the side is sealed by the elastic seal portion 7, the inside of the divided inner cylinder portions 4a and 4b covering the front end portion of the writing shaft 2 between the gaps 3 can be sealed. The amount of evaporation from which ink is evaporated from the pen tip 2a of 2) can be suppressed, and dust can be prevented from invading.
또, 본 실시예에서와 같이 양 내통부(4a,4b)에 원뿔대 모양을한 공간(3a)을 형성하는 테이퍼부(14)외에 원통형공간(3b)을 형성하게 되는 평행부(15)를 설치하게 되는 경우에는 필기축체(2)내의 잉크량이 적고 공기량이 많은때 내부온도가 상승해서 내부공기가 팽창하게 되면, 팽창공기를 원뿔대형 공간(3a)과 원통형공간(3b)으로 유출시켜 잉크가 넘혀 나오지 못하도록 하기 때문에 바람직하다.In addition, as in the present embodiment, parallel portions 15 are formed to form a cylindrical space 3b in addition to the tapered portion 14 which forms a conical shaped space 3a in both inner cylinder portions 4a and 4b. In the case where the amount of ink in the writing shaft 2 is small and the amount of air is large, when the internal temperature rises and the internal air expands, the expanded air flows out into the truncated space 3a and the cylindrical space 3b and the ink overflows. It is preferable because it prevents it from coming out.
또, 이와 같이 일부를 원뿔대형상으로 만들면 필기축체(2)가 되돌려질때 내통부(4a,4b)의 탄성복원력을 높여줄 수가 있어 바람직하다. 또한 한쪽끝이 개폐될 수 있도록 된 내통(4)은 폐쇄단부에 슬리트를 단지 형성시켜 놓는 구조로 해놓아도 좋다.In addition, if a portion is made into a truncated cone shape in this manner, the elastic restoring force of the inner cylinder portions 4a and 4b can be increased when the writing shaft 2 is returned. Moreover, the inner cylinder 4 which one end can open and close may be made into the structure which only forms a slit in a closed end.
이상과 같이 본 고안에 의하면, 한쪽끝을 개폐시켜 줄수 있도록된 내통(4)을 그 개폐단부에다 외통(1)의 선단부(1a)내면과 맞닿게 되는 탄성접편(12a,12b)을 갖는 탄성체로 구성시키고, 이 내통(4)의 후단날개부(9)를 외통(1)의 선단부(1a)내주면에 걸려 끼워놓은 형태로 해놓았기 때문에 내통(4)이 벌려진 상태에 있을때 필기축체(2)의 펜끝(2a)부분이 내통(1)의 탄성복원력과 외통(1)의 선단부(1a)내면에 닿아있는 탄성접편(12a,12b)의 탄성복원력으로 상기 내통(4)의 개폐단부 사이에 압접지지되어져 있게 되고, 그 때문에 펜끝(2a)부분과 외통(1)의 선단구 사이에 틈새가 있게 되더라도 필기할때 흔들려지는 일이 없이 필기하기가 쉽게될 뿐만 아니라, 한쪽 끝이 개폐되어질 수 있도록 된 내통(4)은 그 후단날개부(9)가 외통(1)의 선단부(1a)내주면에 걸려 끼워지면서 개폐단부의 탄성접편(12a,12b)이 외통(1)의 선단부(1a)내면에 맞닿아져 있기 때문에 내통(1)을 안정되게 지지해줄 수 있게 된다.According to the present invention as described above, the inner cylinder (4) that can open and close one end is an elastic body having elastic contact pieces (12a, 12b) in contact with the inner end of the outer end portion (1a) of the outer cylinder (1) When the inner cylinder 4 is in the open state, the writing shaft body 2 is formed because the rear wing portion 9 of the inner cylinder 4 is formed in such a manner as to be hooked on the inner circumferential surface of the front end portion 1a of the outer cylinder 1. Press-fit between the opening and closing ends of the inner cylinder 4 with the elastic restoring force of the elastic contact pieces 12a and 12b in contact with the elastic restoring force of the inner cylinder 1 and the inner surface of the distal end portion 1a of the outer cylinder 1. It is supported, so that even if there is a gap between the tip portion of the pen tip 2a and the tip of the outer cylinder 1, the writing is not only shaken when writing, but also one end can be opened and closed. The inner cylinder 4 is opened and closed while the rear wing portion 9 is fitted to the inner circumferential surface of the distal end portion 1a of the outer cylinder 1. Since parts of the elastic contact piece (12a, 12b) there becomes contact with the fit to the distal end portion (1a), the inner surface of the outer tube (1) is able to give a stable support for the inner tube (1).
