본 고안은 비디오 테이프 카세트에서 비디오 테이프가 감겨지는 릴(REEL)이 이탈되지 않고 회전될 수 있도록 탄지해 주는 지지스프링(SUPPORT SPRING)에 관한 것으로, 특히 릴에 직접 설치된 지지스프링 구조에 관한 것이다.The present invention relates to a support spring for supporting the reel (REEL) in which the video tape is wound in the video tape cassette to be rotated without being separated, and more particularly, to a support spring structure directly installed on the reel.
예시도면 제1도와 같이, 종래의 비디오 테이프 카세트는 많은 부품으로 구성되어 있지만, 본 고안과 관련된 지지스프링 설치부분을 살펴보면, 상부케이스(1)의 내측에 지지스프링(2)이 돌기부(3)에 융착된 상태로 결합되어 있고, 그 양측의 탄지부(4)가 하부케이스(5)내에 안치된 릴(6)의 중심축(7)을 예시도면 제2도와 같이 눌러주도록 되어 있으며, 허브의 중심축(7)은 릴(6)의 상부판(8)을 웰딩시킬때 함께 결합하도록 되어 있었다.Exemplary Drawing As shown in FIG. 1, the conventional video tape cassette is composed of many parts, but when looking at the supporting spring installation part related to the present invention, the support spring 2 is provided on the inside of the upper case 1 to the protrusion 3. It is coupled in a fused state, and both sides of the finger portion 4 press the central axis 7 of the reel 6 placed in the lower case 5 as shown in FIG. The shaft 7 was adapted to join together when welding the top plate 8 of the reel 6.
그런데, 상기한 바와 같이 종래의 지지스프링(2)은 스테인레스 스틸 재질로서 탄성을 유지시켜 주기 위한 절곡상태를 정밀하게 가공시켜야 하고, 지지스프링과 릴의 중심축이 각각 분할되어 있기 때문에 조립시 각각의 공정이 필요하며, 이에 따라 생산 및 조립시에 불량 발생율이 높아서 생산성이 저하되는 결점이 있었다.However, as described above, the conventional support spring 2 is made of stainless steel and must be precisely processed in a bent state to maintain elasticity, and since the center axes of the support spring and the reel are divided, respectively, There is a drawback that the process is required, and thus productivity is lowered due to a high rate of defects during production and assembly.
본 고안은 상기와 같은 종래의 지지스프링과 중심축이 갖는 제결점을 해결하기 위하여 안출된 것으로, 지지스프링과 중심축을 단일구조로 된 지지스프링으로 구성하여 상부판에 결합함으로서, 지지스프링의 역할과 중심축의 역할을 겸하여 할수 있도록 하고, 따라서 조립공정이 간단한 지지스프링을 제공함에 목적이 있다.The present invention was devised to solve the drawbacks of the conventional support spring and the central axis as described above, by combining the support spring and the central axis as a single structure of the support spring to the upper plate, the role of the support spring and Its purpose is to serve as a central axis, and therefore the assembly process aims to provide a simple support spring.
이를 위해 릴의 허브내부, 즉 종래의 중심축 형성부위에 ""형상의 스프링을 조립설치시키고, 상·하부케이스를 조립할때에는 상기 스프링이 다소 압착되는 상태로 릴를 탄지하므로서 종래의 지지스프링 기능은 동일하지만 그 구성과 조립이 간단한 특징을 갖는 것이다.For this purpose, inside the hub of the reel, i. "When assembling and installing the shape of the spring, and when assembling the upper case and the lower case, while holding the reel in a state that the spring is slightly compressed, the conventional support spring function is the same, but its configuration and assembly has a simple feature.
본 고안을 첨부된 예시도면과 함께 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.
본 고안은 "" 형상의 지지스프링(21)으로 그 상단부(22)로부터 탄발력을 갖는 3개의 다리(23)가 각각 하향 굴곡되어 ""형을 이루면서 하단에는 수평단부(24)가 형성된 것이며, 상기 상단부(22)가 접촉되는 상부케이스(1) 내면에는 접촉편(25)을 형성시키되, 양측릴(공급릴과 감기릴)에 동일하게 적용시켜 이루어지는 것이다.This design is " "The supporting springs 21 are three curved legs 23 which have elasticity from their upper ends 22, respectively. "Forming a shape, the lower end is formed with a horizontal end 24, the upper case 22 is in contact with the inner surface of the upper case 1 to form a contact piece 25, the same on both side reel (feeding reel and winding reel) It is made by applying it.
또한, 상기 지지스프링(21) 설치를 위해 릴의 하부판(9)의 릴허브(15)상에 지지스프링 안치부(10)와 융착용 돌기부(11)를 형성시키고, 릴상부판(8)에는 결합구(12) 및 관통구(13)를 형성시켜서 융착용 돌기부(13)와 짝을 이루게하며, 미설명부호14는 융착단이고, 지지스프링(21)은 릴재질과 같거나 유사한 것으로 한다.Further, in order to install the support springs 21, the support spring settling portion 10 and the fusion protrusion 11 are formed on the reel hub 15 of the lower plate 9 of the reel. The coupling hole 12 and the through hole 13 are formed so as to mate with the fusion protrusion 13, and reference numeral 14 is a fusion end, and the support spring 21 is the same as or similar to the reel material.
예시도면 제4도 및 제5도는 본 고안의 조립 예시도로써, 지지스프링(21)을 하부판(9)의 안치부(10)에 그 단부(24)가 놓여지게 한뒤 상부판(8)을 하부판(9)과 조립시키면 지지스프링(21)의 상단부(22)가 상부판(8)의 관통구(13)을 통하여 상부로 관통되어 돌출되고, 동시에 하부판(9)의 융착용 돌기부(11)도 상부판(8)의 결합구(12)를 통하여 상부판(8)의 상부로 돌출된다.4 and 5 are assemblings of the present invention, the support spring 21 of the lower plate (9) to the end portion 24 of the end plate 24 is placed, the upper plate (8) the lower plate When assembled with the (9), the upper end portion 22 of the support spring 21 penetrates upward through the through hole 13 of the upper plate 8, and protrudes, and at the same time, the fusion protrusion 11 of the lower plate 9 is also It protrudes to the upper part of the upper plate 8 through the coupling hole 12 of the upper plate 8.
따라서 예시도면 제5도와 같이, 융착용 돌기부(11)상단을 융착시키면 융착단(14)이 형성되어 지지스프링(21)은 릴의 허브(15)에 견고히 고정되는 것이다.Accordingly, as shown in FIG. 5, when the upper end of the fusion protrusion 11 is fused, the fusion end 14 is formed, and the support spring 21 is firmly fixed to the hub 15 of the reel.
위와 같이 지지스프링(21)이 고정된 상태에서 릴(6)을 하부케이스(5)에 안치시키고, 상부케이스(1)를 결합하게 되면, 상부케이스(1)의 내측하부로 돌설시킨 접촉편(25)이 예시도면 제6도와 같이, 지지스프링(21)의 상단부(22)를 압압하여 다리(23)가 사방으로 납작하게 벌어지면서 낮아지고 (점선위치에서 실선위치로), 결국 릴(6)은 탄발력을 받아 이탈이 방지되는 것이다.When the reel 6 is placed in the lower case 5 while the support spring 21 is fixed as above, and the upper case 1 is coupled, the contact piece protrudes into the inner lower portion of the upper case 1 ( 25, as shown in FIG. 6, the upper end 22 of the support spring 21 is pressed to lower the leg 23 while being flattened in all directions (from the dotted line to the solid line), and eventually the reel 6 Is a shot force to prevent the departure.
이와 같이, 본 고안은 지지스프링(21)이 상부케이스(1)에 눌리게 되면 외측으로 완만히 구부러져 있던 다리(23)가 압력을 받아서 눌리게 되고, 이러한 탄발력은 릴(6)을 지속적으로 눌러서 안정시키게 되며, 지지스프링(21)의 상단부(22)는 구형으로 둥글게 되어 있어서 접촉편(25)에 의해 눌린 상태에서도 원활한 회전이 가능한 것이다.As such, the present invention, when the support spring 21 is pressed on the upper case 1, the leg 23, which was gently bent to the outside, is pressed under pressure, and the elastic force is continuously pressed by the reel 6 It is to be stabilized, the upper end portion 22 of the support spring 21 is rounded in a spherical shape so that smooth rotation is possible even in the state pressed by the contact piece (25).
한편, 지지스프링(21)은 다리(23)가 3개인 예를 도시하였으나, 이에 한정되는 것은 아니며, 탄발력을 갖는 구조라면 3개 이하 또는 2이상이어도 좋은 것이다.On the other hand, the support spring 21 is shown an example of three legs 23, but is not limited to this, it may be three or less or two or more as long as the structure having elasticity.
상기한 본 고안을 사용함에 따라 지지스프링(21) 자체가 탄발력을 갖도록 되어 있어서, 종래의 지지스프링(2)과 중심축(7)의 역할을 동시에 할 수 있고, 또한 종래의 중심축(7)을 릴(6)에 결합하는 방법과 동일한 공정에 의해 조립할 수 있으므로 공정을 간단히 하면서도 재료절감 및 생산성을 향상시키는 효과가 있다.By using the present invention described above, the support spring 21 itself has elasticity, so that it can simultaneously serve as the conventional support spring 2 and the central axis 7, and also the conventional central axis 7 ) Can be assembled by the same process as the method of coupling to the reel (6), thereby simplifying the process and improving the material savings and productivity.
