본 고안은 비데오 테이프 레코더의 데크 메타니즘에 있어서, 각기 종류의 레버류 이를테면 텐션아암 이라든가, 핀치롤러암을 비롯한 모든 레버류 특히, 그 중에서도 서플라이 릴, 테이크 엎 릴 등에 브레이크를 걸어주기 위한 암들과 같이 합성수지로 사출 형성되는 레버류들의 축 고정에 적합한 고안이다.In the deck mechanism of the video tape recorder, the present invention is to provide various types of levers, such as tension arms, pinch roller arms, all the levers, especially the supply reel, take-up arm, etc. It is a device suitable for fixing the shaft of levers that are injection-molded with synthetic resin.
데크 메카니즘은 많은 부품들이 매우 정밀하게 조립되어 있는데 곳곳에 각기 목적의 레버들이 있는 것을 알수 있다.The deck mechanism has many parts assembled very precisely, and there are levers for each purpose.
이들을 축 고정하는데 있어서, 종래에는 제2도 a, b와 같이 메인샤시(20)에 압입 고정된 고정축(21)에 각종 레버류(22)를 결합하되, 이 레버(22)류가 고정축(21)에서 이탈되지 않도록 하기 위해 고정축 형태에 따라 E링(23) 또는 C(24)을 체결하였다. 즉, 많은 레버류들을 고정하기 위해 별도의 링을 각각 사용해야 하므로 부품수가 증가되고, 이들을 조립하는 시간이 장시간 소용되어 조립이 확실히 안되었을때 부품 이탈 등으로 데크 동작이 안되는 등 문제점이 있는 것이다.In fixing these shafts, conventionally, various levers 22 are coupled to a fixed shaft 21 that is press-fitted to the main chassis 20 as shown in FIGS. 2 and 2, but the levers 22 are fixed shafts. In order not to be separated from (21), the E-ring 23 or C (24) was fastened depending on the shape of the fixed shaft. That is, the number of parts is increased because each separate ring must be used to fix a large number of levers, and there is a problem such that the deck operation does not work due to component detachment when the assembly time is used for a long time.
본 고안은 이와 같은 종래의 문제점을 해결하기 위하여 안출한 것으로서, 레버류 특히 합성수지제 레버류를 조립할때 별도의 링 사용을 배제하고 직접 축에서 이탈되지 않도록 결합되게 하므로써 부품수를 줄임과 동시에 조립 작업에 능률을 기하고자 목적한 것이다.The present invention was devised to solve such a conventional problem, and when assembling levers, especially synthetic resin levers, the assembly work is reduced and the number of parts is reduced by eliminating the use of a separate ring and being combined so as not to be detached directly from the shaft. The purpose is to be efficient.
이하, 본 고안의 구성과 작용효과를 첨부도면 제1도에 의거하여 설명하면 다음과 같다.Hereinafter, the configuration and operation effects of the present invention will be described based on the accompanying drawings of FIG. 1.
본 고안은 구성은 데크 메카니즘의 메인샤시(1)에 금속제 고정축(2)이 압입 고정되고, 이에 통상의 합성수지제 레버(3)류의 축받이부(4)가 임의로 회전되게 결합된 것에 있어서, 고정축(2)의 상부 외주면을 따라 둘레홈(2')을 요입 형성하고 레버(3)류의 축받이부(4)의 중심부에 형성된 삽입공(5)내주면의 상부에는 둘레홈(2')에 대응하여 걸림턱(6)을 일체로 형성하되, 걸림턱(6)은 그 하방 좌측으로 경사지도록 하는 턱면(6')으로 형성하고, 축받이부(4)의 삽입공(5) 내부로 고정축(2)이 삽입되도록 하되, 경사진 턱면(6')이 고정축(2)의 상단 모서리부에 접촉되는 시점에서 축받이부(4)을 압압시키면, 걸림턱(6)이 레버(3)와 함께 외측으로 밀려남과 동시에 둘레홈(2')에 턱면(6')이 진입되어 걸림턱(6)은 탄성에 의해 복귀되어 둘레홈(2')에 삽입될수 있도록 한 것이다According to the present invention, the fixed shaft 2 made of metal is press-fitted to the main chassis 1 of the deck mechanism, and the bearing portion 4 of the ordinary synthetic resin levers 3 is rotatably coupled to the main chassis 1 of the deck mechanism. A circumferential groove 2 'is formed along the upper outer circumferential surface of the fixed shaft 2, and a circumferential groove 2' is formed at the upper part of the inner circumferential surface of the insertion hole 5 formed in the center of the bearing portion 4 of the levers 3. Correspondingly, the locking jaw 6 is integrally formed, but the locking jaw 6 is formed as a jaw surface 6 'to be inclined downward to the left and fixed to the insertion hole 5 of the bearing 4. The shaft 2 is inserted, but when the inclined jaw surface 6 'contacts the upper edge of the fixed shaft 2, pressing the bearing portion 4, the locking jaw 6 causes the lever 3 And pushed outwards and at the same time the jaw surface 6 'enters the circumferential groove 2' and the locking jaw 6 is returned by elasticity so that it can be inserted into the circumferential groove 2 '.
상기와 같이 고정축(2')에 결합된 레버(3)는 삽입공(5) 내주면의 일부에 돌출된 걸림턱(6)이 고정축(2)의 둘레홈(2')에 걸려서 이탈되지 않음과 동시에 둘레홈(2')을 따라 걸림턱(6)이 회동 가능한 것이므로, 레버(3)는 고정축(2)을 중심으로 통상과 같이 회전 동작될수 있는 것이다.As described above, the lever 3 coupled to the fixed shaft 2 ′ is not detached by the locking jaw 6 protruding from a part of the inner circumferential surface of the insertion hole 5 by the circumferential groove 2 ′ of the fixed shaft 2. At the same time, since the locking jaw 6 is rotatable along the circumferential groove 2 ', the lever 3 can be rotated as usual with respect to the fixed shaft 2.
이와 같이 본 고안레버(3)류를 고정축(2)에 최초 조립할때에는, 메인샤시(1)에 압입 고정된 고정축(2) 상부에 레버(3)류의 축받이부(4) 중심의 삽입공(5)을 대응하여 일치시킨 상태에서, 힘을 가하여 축받이부(4)를 하방으로 누러면 고정축(2)은 금속제이고 레버(3)와 함께 걸림턱(6)은 합성수지제로 되어 있어 레버(3)와 걸림턱(6)은 외측으로 밀려남과 동시에 걸림턱(6)의 경사진 턱면(6')은 고정축(2)의 상단부 모서리를 타고 하방으로 미끄러져 내려와 둘레홈(2')에 탄력 결합되는 것이다.In this way, when the present invention levers 3 are assembled to the fixed shaft 2 for the first time, the center of the bearing portion 4 of the levers 3 is inserted into the upper portion of the fixed shaft 2 that is press-fitted to the main chassis 1. In the state where the ball 5 is correspondingly matched, when the bearing portion 4 is pressed downward by applying a force, the fixed shaft 2 is made of metal and the locking jaw 6 together with the lever 3 is made of synthetic resin. (3) and the locking jaw (6) is pushed out and at the same time the inclined jaw surface (6 ') of the locking jaw (6) is slipped downward through the upper edge of the fixed shaft (2) and the peripheral groove (2') Will be elastically coupled to.
이상과 같이 하므로써 축에 결합된 레버를 고정축을 중심으로 이탈되지 않고 회전되므로, 종래와 같이 별도의 E링 또는 C링을 사용할 필용가 없어 부품절감은 물론 결합공공정이 단순하여 조립작업이 신속하게 되는 효과를 제공하는 것이다.By doing the above, the lever coupled to the shaft is rotated without being separated about the fixed shaft. Therefore, it is not necessary to use a separate E-ring or C-ring as in the prior art. To provide.
