본 고안은 복합필기구용 캠안내 지지체의 고정구조에 관한 것이다.The present invention relates to a fixed structure of the cam guide support for the composite writing instrument.
종래의 복합필기구용 캠안내 지지체의 고정구조는 제 4 도에서와 같이 상부본체(A') 상단내측에 지지턱(4a')과 함께 형성된 지지공(4')에 캠안내 지지체(B')의 상단에 형성되는 탄성후크(6)가 압압관통되어 상기 지지턱과 함께 형성된 지지공(4')에 캠안내 지지체(B')의 상단에 형성되는 탄성후크(6)가 압압관통되어 상기 지지턱(4a')에 탄성후크(6) 하단의 걸림턱이 걸려 고정설치 되었다. 상기와 같이 캠안내 지지체(B')를 상부본체(A')에 상단내측에 지지턱(4a')과 함께 형성된 지지공(4')에 압압하여 고정설치하기 위해서는 캠안내 지지체(B') 상단에 형성되는 탄성후크(6)는 2쪽으로 분할된 원통형상으로 형성하면서 그 뒷편에 걸림턱을 각각 형성시켜야만 했다.As shown in FIG. 4, the cam guide support for the conventional composite writing instrument has a cam guide support (B ') in a support hole (4') formed with a support jaw (4a ') at the upper inner side of the upper body (A'). The elastic hook 6 formed at the upper end of the cam guide support B 'is formed at the upper end of the cam guide support B' in the supporting hole 4 'formed with the supporting jaw. The locking jaw of the bottom of the elastic hook 6 is fixed to the jaw (4a '). Cam guide support (B ') in order to press the cam guide support (B') in the upper body (A ') to the support hole (4') formed together with the support jaw (4a ') in the upper end on the upper body (A') The elastic hook 6 formed at the upper end had to be formed in the cylindrical shape divided into two sides, and the latching jaw was formed in the back side, respectively.
그것은 탄성후크(6)를 지지턱(4a')과 함께 형성된 상기 지지공(4')에 압압하여 삽입할때 2쪽으로 분할된 원통형상의 탄성후크(6)가 앞쪽끝으로부터 눌려져 들어가기 때문에 그 삽입이 용이하게 되고 탄성후크(6)가 지지공(4')을 관통하게 되면 오므라 들었던 2쪽으로 분할된 원통형상의 탄성후크(6)가 탄성에 의해서 다시 원상복구되어 그 뒷편의 걸림턱이 상기 지지턱(4a')에 걸려 고정되기 때문이다.When the elastic hook 6 is pressed into the supporting hole 4 'formed with the supporting jaw 4a', the cylindrical elastic hook 6 divided into two sides is pressed in from the front end. When the elastic hook 6 penetrates the support hole 4 ', the cylindrical elastic hook 6 divided into two sides, which has been retracted, is restored to its original shape by elasticity. 4a ') is fixed.
그후 상부본체(A')사단 나선부에는 캡(5)이 나사결합되면서 캡(5) 내부에 돌출된 지지핀(5a)이 상기 탄성후크(6)내에 끼워지게 되는데 그것은 2쪽으로 분할된 원통형상의 탄성후크(6)가 오므라지지 않게 해주어 하단의 걸림턱이 상기 지지턱(4a')에 압접되어 걸려지는 것을 견고하게 해주기 때문이다.Thereafter, the cap 5 is screwed into the upper main body A 'end spiral, and a support pin 5a protruding inside the cap 5 is fitted into the elastic hook 6, which is divided into two cylindrical shapes. This is because the elastic hook 6 is prevented from being squeezed so that the lower end of the hooking jaw is pressed against the supporting jaw 4a 'so as to be firmly caught.
그러나 상기와 같은 종래의 캠안내 지지체의 고정구조는 상술한 바와같이 탄성후크(6)를 2쪽으로 분할시켜주어야 하고, 탄성후크(6)내에 끼워지는 지지핀(5a)을 캡(5) 내부에 일체로 성형하여야 하는바 그것은 금형제작상의 어려움을 줄뿐만 아니라 그 사출성형 방법도 까다로워 제작원가 상승의 주된 요인으로 되는 문제점이 있었다.However, as described above, the fixing structure of the conventional cam guide support has to divide the elastic hook 6 into two sides, and the support pin 5a fitted in the elastic hook 6 is provided inside the cap 5. It must be molded integrally, which not only causes difficulties in mold making, but also has a problem that the injection molding method is difficult, which is a major factor in the increase in manufacturing cost.
본 고안은 종래의 문제점을 고려하여 안출된 것으로 2쪽으로 분할된 탄성후크(6)를 사용하지 않고 캡(5)내부에는 지지핀(5a)을 일체로 성형함이 없게 하여 금형제작 및 사출성형의 어려움을 해소하여 제작원가를 크게 절감시킨 복합필기구용 캠안내 지지체의 고정구조를 제공함을 그 목적으로 한다.The present invention has been devised in consideration of the conventional problem, and does not use the elastic hook 6 divided into two sides, so that the support pin 5a is not integrally formed inside the cap 5 so that the mold production and injection molding can be performed. It is an object of the present invention to provide a fixed structure of the cam guide support for composite writing instruments, which greatly reduces the manufacturing cost by eliminating difficulties.
상기한 본 고안의 목적은 상부본체 상단 내측에 지지턱과 함께 형성된 지지공에 캠안내 지지체 상단 걸림축의 끝단부를 압압관통시켜 회전가능하게 고정하는 통상의 캠안내 지지체의 고정구조에 있어서, 상기 상부본체 상단내측에 지지공과 함께 구성되어 있는 지지턱 일측에 결합안내홈을 요설하고 상기 캠안내 지지체의 상단걸림축 끝단 일측 외주면에는 안내면과 걸림턱을 구비한 결합돌기를 돌설하고 다른 일측 외주면에는 안내면과 걸림턱을 구비한 결합안내돌기를 상기 결합돌기에 대향하게 돌설한 것을 특징으로 하는 복합필기구용 "캠안내 지지체의 고정구조"에 의해 달성되어 지는바 이하 첨부한 도면의 실시예에 따라 본 고안을 상세히 설명한다.The object of the present invention is a fixing structure of a conventional cam guide support for rotatably fixing the end of the cam guide support upper locking shaft to the support hole formed with a support jaw in the upper inner upper body, the upper body The coupling guide groove is provided on one side of the support jaw formed with the support hole in the upper side, and the coupling protrusion having a guide surface and a locking jaw is protruded on one outer circumferential surface of the upper locking shaft end of the cam guide support, and the guide surface is engaged on the other outer circumferential surface. According to the embodiment of the accompanying drawings, the present invention is achieved in detail by the "fixing structure of the cam guide support" for the composite writing instrument, which is characterized by protruding the coupling guide protrusion having the jaw to face the coupling protrusion. Explain.
본 고안은 제 1 도에서 알 수 있는 바와같이 상부본체(A) 상단 내측에 지지공(4)을 함께 구성하고 있는 지지턱(4a) 일측에 결합안내홈(4b)을 요설하고, 캠안내 지지체(B)의 상단걸림축(1) 끝단 일측의 외주면에는 안내면(2a)와 걸림턱(2b)을 구비한 결합돌기(2)를 돌설하고, 다른 일측 외주면에는 안내면(3a)과 걸림턱(3b)을 구비한 안내결합돌기(3)을 상기 결합돌기(2)에 대향 돌설하여서 구성되어진다.The present invention, as can be seen in Figure 1, the coupling guide groove (4b) on one side of the support jaw (4a) that together constitutes the support hole (4) in the upper body (A) upper inner side, the cam guide support (B) the outer peripheral surface of one end of the upper engaging shaft (1) protrudes the engaging projection (2) having a guide surface (2a) and the locking jaw (2b), and the other one outer peripheral surface of the guide surface (3a) and the locking jaw (3b) The guide coupling protrusion (3) provided with) is formed by opposing the coupling protrusion (2).
본 고안의 캠안내 지지체(B)를 상부본체(A)에 결합하기 위해서는 먼저 상부본체(A)상단 내측의 지지턱(4a)과 함께 형성된 지지공(4)과 결합안내홈(4b)에 캠안내 지지체(B)의 상단 걸림축(1) 끝단 외주연에 돌설된 결합돌기(2)와 안내결합돌기(3)를 각각 위치시켜 압압하여 관통시킨다.In order to combine the cam guide support B of the present invention to the upper body (A), the cam in the support hole 4 and the coupling guide groove (4b) formed together with the support jaw (4a) of the upper inside of the upper body (A) first Coupling protrusions 2 and guide coupling protrusions 3 protruding on the outer circumference of the upper end of the engaging shaft 1 of the guide support B are respectively positioned and pressed to penetrate.
지지턱(4a)측에 요설된 상기 결합 안내홈(4b)은 안내결합돌기(3)의 높이보다 다소 깊게 요설되어 있는데 그것은 상기 결합돌기(2)와 안내결합돌기(3)를 상기 지지공(4)과 안내홈(4b)에 각각 위치시켜 압압관통 시킬 때 안내홈(4b)이 깊게 요설되어 있기 때문에 지지공(4)이 탄성에 의해 다소 벌어져 확대되므로 결합돌기(2)와 안내결합돌기(3)가 다소 쉽게 상기 지지공(4)와 결합안내홈(4b)을 통과할 수 있기 때문이다.The coupling guide groove 4b, which is provided on the support jaw 4a side, is recessed slightly deeper than the height of the guide coupling protrusion 3, which is connected to the coupling protrusion 2 and the guide coupling protrusion 3 by the support hole ( 4) and the guide grooves 4b are deeply concaved when press-through through and positioned in the guide grooves 4b, respectively, so that the support holes 4 are slightly enlarged and expanded by elasticity, so that the engaging protrusions 2 and the guide coupling protrusions ( This is because 3) can pass through the support hole 4 and the coupling guide groove 4b more easily.
이렇게 관통된 상태에서 상기 안내결합돌기(3)가 안내홈(4b)에서 벗어나도록 일측으로 돌려 고정시키면 제 2 도에서와 같이 본 고안은 캠안내 지지체(B)상단 걸림축(1) 끝단 외주면에 돌설된 결합돌기(2)와 안내결합돌기(3)의 하단에 형성되어 있는 걸림턱이(2b)(3b) 상부본체(A)의 내측상단의 지지턱(4a)상단의 나선부에는 지지핀(5a)이 없는 통상의 캡(5)을 나사결합하면 전체적인 조립이 끝나는 것이다.When the guide coupling protrusion 3 is rotated to one side so as to escape from the guide groove 4b in the penetrated state, the present invention, as shown in FIG. 2, has an outer peripheral surface at the end of the cam guide support B. A support pin is formed on the spiral portion of the upper end of the support jaw 4a at the inner upper end of the upper body A of the engaging jaw formed at the lower end of the protruding coupling protrusion 2 and the guide coupling protrusion 3. If the ordinary cap 5 without (5a) is screwed in, the overall assembly is completed.
제 3 도는 본 고안의 작동상태로서 사용자가 볼펜 또는 샤프로 선택사용할때에는 상부본체(A)을 좌, 우로 90°씩 회전시키면 사용자의 선택에 따라 상부본체(A)가 걸림축(1)를 중심으로 하여 좌, 우로 90°씩 쉽게 회전되어 볼펜이나 샤프로 선택되어진다.3 is an operating state of the present invention, when the user selects and uses a ballpoint pen or a sharp, and rotates the upper body A by 90 ° left and right, the upper body A is centered on the locking shaft 1 according to the user's selection. It can be easily rotated by 90 ° left or right to select a ballpoint pen or sharp.
이와 같이 본 고안은 종래의 문제점을 해결하여 금형제작이 용이하고 그 사출성형방법도 간단하여 제작원가를 크게 절감할 뿐만 아니라 그 조립이나 작동도 손쉽게 할 수 있는 아주 유용한 고안인 것이다.In this way, the present invention is a very useful design that can easily manufacture the mold by solving the conventional problems and the injection molding method is simple, as well as greatly reducing the manufacturing cost, as well as the assembly or operation.
