본 고안은 비디오 테이프 카세트의 테이프 로딩(Loading)부 보호를 위한 커버(COVER) 탄지용 록킹부재에 관한 것이다.The present invention relates to a cover member for locking the cover for protecting the tape loading portion of the video tape cassette.
상, 하부케이스로 구성 조립되는 비디오 카세트는 테이프가 로딩되는 전면에 커버가 힌지 고정되어 있어서, VRT에 장전시에는 커버가 열리면서 테이프가 VTR의 헤드에 접촉되도록 노출되고, 비장전시(보관시)에는 커버가 닫혀서 테이프를 보호해 주게 된다.The video cassette, which is composed of upper and lower cases, is hinged and fixed to the front surface where the tape is loaded, so that when the VRT is loaded, the cover is opened and the tape is exposed to contact the head of the VTR. The cover closes to protect the tape.
이와 같이 선택적으로 커버의 개폐동작을 할 수 있도록 록킹시키는 커버 록킹부재(1)는 제1도에서와 같이, 하부케이스(10)의 격실(12)의 내에 탄착되도록 양 힌지봉(14)과 걸림돌기(16), 해제돌기(18), 탄성편(20) 및 광경로홀(22)이 형성된 구조이고, 격실(12)은 외벽(24)에 걸림돌기 관통구(26)와 해제돌기 관통구(28)가 형성되며, 양측벽은 지지대(30)로 구성되며, 이 지지대(30)를 잇는 내벽이 안쪽으로 형성되어 구성된다.In this way, the cover locking member 1 that locks to selectively open and close the cover is as shown in FIG. 1, both hinge rods 14 and the obstacles to be secured in the compartment 12 of the lower case 10. Group 16, the release protrusion 18, the elastic piece 20 and the optical path hole 22 is formed, the compartment 12 has a locking projection through hole 26 and the release projection through hole in the outer wall (24) A 28 is formed, and both side walls are comprised of the support 30, and the inner wall which connects this support 30 is formed inward.
또한 지지대(30) 상단면은 상기 커버 록킹부재(1)의 양 힌지봉(14)이 유착되도록 요(凹)홈(32)이 형성되어 있으며, 도면중 미설명부호 5는 걸림홈, 34는 광경로홀, 36은 상부케이스, 38을 커버, 40은 끼움봉, 42는 스프링이다.In addition, the upper surface of the support 30 is formed with a groove (32) so that both the hinge rods 14 of the cover locking member (1), the reference numeral 5 in the drawing is a locking groove, 34 Light path hole, 36 is upper case, 38 is cover, 40 is fitting rod, 42 is spring.
따라서, 비디오 카세트 조립순서에 따라 록킹부재(1, 이하 "록킹부재"라 함)를 체결할 때는 커버 록킹부재(1)를 격실(12) 내에 끼우되, 걸림돌기(16) 및 해제돌기(18)가 각 관통구(26)(28)에 관통 돌출되게 하면, 그 힌지봉(14)은 지지대(30)의 요홈(32)에 유착되며 탄성편(20)은 록킹부재(1)가 힌지봉(14)을 중심으로 회동되는 탄력을 발휘하여 걸림돌기(16) 및 해제돌기(18)가 관통구(26)(28)로 돌출되어져 있는 상태, 즉 상기 걸림돌기(16)가 커버의 걸림홈(5)에 끼워지게 되므로써 커버(38)가 열려지지 않는 상태를 유지시켜 준다.Therefore, when the locking member 1 (hereinafter referred to as the "locking member") is fastened in accordance with the video cassette assembly procedure, the cover locking member 1 is inserted into the compartment 12, but the locking projections 16 and the release projections 18 When the through hole 26 and 28 are projected through, the hinge rod 14 is brought into contact with the groove 32 of the support 30 and the elastic piece 20 has the locking member 1 as the hinge rod. The locking protrusion 16 and the release protrusion 18 are protruded through the through holes 26 and 28 by exerting the elasticity that is rotated about the 14, that is, the locking protrusion 16 is the locking groove of the cover. Since the cover 38 is fitted to (5), the cover 38 is kept open.
그런데, 도면에서도 알 수 있듯이 종래의 커버 록킹부재(1)는 지지대(30)에 얹혀진 상태에서 걸림돌기(16)가 관통구(26)를 통해 커버(38)의 걸림홈(5)에 탄지되기 때문에 커버(38)가 임으로 열리지 않게 되는 것이며, 그 탄지력은 탄성편(20)에 의해서만 상기 돌기(16)(18)가 관통구(26)(28)로 돌출되는 탄력을 발휘하는 것이어서, 탄성편(20)은 일정한 힘을 계속 받고 있기 때문에 장시간 사용에 따라 탄성력이 서서히 저하되며, 변형도 심하여 커버(38)가 임으로 열리게 되는 등 기능에 문제가 있게 된다. 이러한 현상은 중심면(48)에서부터 탄성편(20) 길이가 짧은 것도 큰 이유이며, 탄성편(20)과 커버 록킹부재(1)가 일체로 된 동재질의 것이어서 더욱 탄성 저하 요인이 컸었다.By the way, as can be seen in the drawing, the conventional cover locking member 1 is supported on the locking groove 5 of the cover 38 through the through hole 26 while the locking projection 16 is placed on the support 30. Therefore, the cover 38 does not open at random, and the grip force exerts the elasticity that the protrusions 16 and 18 protrude into the through holes 26 and 28 only by the elastic pieces 20, thereby providing elasticity. Since the piece 20 continues to be subjected to a constant force, the elastic force gradually decreases with use for a long time, and the deformation is so severe that the cover 38 is opened arbitrarily, such that there is a problem in function. This phenomenon is the reason why the length of the elastic piece 20 is short from the central plane 48, and the elastic piece 20 and the cover locking member 1 are made of the same material as one body, and thus the elastic deterioration factor was greater.
이에 본 고안에서는 상기의 록킹부재가 언제나 균일한 탄성력을 보유하는 구조로 개량시킨 것이며, 이를 위해 광경로홀이 최소한의 구조를 유지시킨채 중량을 감소시키는 형상을 안출한 것이다.Therefore, in the present invention, the locking member is improved to a structure that always maintains a uniform elastic force, and for this purpose, the optical path hole is designed to reduce the weight while maintaining the minimum structure.
즉,종래의 록킹부재는 양 힌지봉(14)을 중심으로 평판형태로 제작된 채 광경로홀(22)이 천공되어진 구조였지만, 본 고안은 양 힌지봉을 중심으로 해제돌기 및 걸림돌기가 형성된 위치까지 모두 따내어 마치 "U"자형의 구조를 갖도록 하고, 이 때문에 광경로홀도 그 위치만 나타내어질 정도의 초경량 구조를 이룩한 것이다.That is, the conventional locking member was a structure in which the light path hole 22 was perforated while being manufactured in a flat shape around both hinge rods 14, but the present invention has a position where release protrusions and locking protrusions are formed around both hinge rods. All of them are taken out to have a "U" shaped structure, which is why the optical path hole also has an ultra-light structure that can only show its position.
이하, 첨부도면을 참고하여 본 고안을 상술한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 카세트커버(38) 록킹용 록킹부재(1)에 있어서, 양 힌지봉(14) 사이의 중심면(48) 상변을 해제돌기(18)와 인접하는 위치까지 하향시켜 내곡홈(50)을 형성시키고, 내곡홈(50) 중심위치에서 상방수직으로 탄성편(20)을 형성시키되, 상기 탄성편(20) 우변은 광경로홀(22)의 일변을 구성하도록 하고, 상기 광경로홀(22)은 상부가 개방되도록 하여 구성시킨 특징을 갖는 것이다.In the present invention, in the locking member (1) for locking the cassette cover (38), the upper surface of the center surface (48) between both hinge rods (14) is lowered to a position adjacent to the release protrusion (18). To form, and to form the elastic piece 20 in the vertical direction at the central position of the inner groove 50, the right side of the elastic piece 20 to constitute one side of the optical path hole 22, the optical path hole ( 22) has a feature configured to open the top.
제4도는 본 고안의 사시도로써, 커버 록킹부재(1)는 광경로홀(22)과 내곡홈(50) 사이에 탄성편(20)이 형성되어 뫼산(山)자를 구성하는 구조를 이루며, 광경로홀(22)의 상부가 개방된 것은 광경로홀(34)과 일치되는 관통구가 확보되면 되는 것이어서 탄성편(20) 일측으로 광경로홀(34)을 구성하도록 하였다.4 is a perspective view of the present invention, the cover locking member 1 is formed between the optical path hole 22 and the inner groove 50, the elastic piece 20 is formed to form a structure of the Mt. The upper part of the furnace hole 22 is opened so that a through hole corresponding to the optical path hole 34 may be secured, so that the optical path hole 34 is formed at one side of the elastic piece 20.
상기한 구성의 본 고안을 설치함에 있어서는 통상의 방식대로 록킹부재(1)를 지지대(30)상에 체결시켜서 양 힌지봉(14)이 요홈(32)내에 유착되도록 한다.In installing the present invention having the above-described configuration, the locking member 1 is fastened to the support 30 in the usual manner so that both hinge rods 14 are brought into the groove 32.
이어서, 상부케이스(36)를 하부케이스(10)에 결합 체결시키게 되면, 종래와 같이 탄성편(20)이 슬라이딩 되면서 압착되므로, 상기 록킹부재(1)는 힌지봉(14)을 중심으로 시계방향으로 회동되는 탄력을 갖게 된다.Subsequently, when the upper case 36 is coupled and fastened to the lower case 10, since the elastic piece 20 is squeezed while sliding as in the related art, the locking member 1 is clockwise around the hinge rod 14. It will have the elasticity to rotate.
따라서, 이 탄력이 상기 걸림돌기(16)와 해제돌기(18)를 그 관통구(26)(28)로 밀어주는 힘이 되므로(제3도 참조), 록킹부재(1)의 원래 기능, 즉 커버(38)를 탄지하기 위해 걸림돌기(16)가 커버(38)의 걸림홈(5)에 탄착되도록 돌출되어진 상태가 확실하게 유지되는 것이다.Therefore, since this elasticity is a force for pushing the locking projections 16 and the release projections 18 to the through holes 26 and 28 (see FIG. 3), the original function of the locking member 1, namely In order to support the cover 38, the state in which the locking protrusion 16 protrudes to be securely attached to the locking groove 5 of the cover 38 is surely maintained.
한편, 상기한 예에서는 내곡홈(50)을 보다 깊게 형성시켜서 재료의 절감과 탄성편(20)의 탄성기능을 극대화 시키고자 하였으나, 탄성편(20)을 단순히 걸림돌기(16)와 반대쪽으로 경사지게 형성시킨것에 한정하지 않고, 제5도에서와 같이 중앙부위에 절곡부(44)를 형성시켜 탄력을 증대시켜도 좋고, 제6도에서와 같이 그 선단에 슬라이딩부(46)를 형성시켜서 해도 좋으며, 제7도에서와 같이 탄성편(20)의 선단에 ""부(47)를 형성시켜서, 상기 록킹부재(1) 회동시 다소 늘어나는 탄성편(20)의 마찰력을 줄여줄 수 있도록 할 수도 있다. 또한, 내곡홈(50)의 하변을 해제돌기(18) 위치까지 파내어도 좋은 것이다.On the other hand, in the above example, the inner groove 50 is formed deeper to reduce the material and maximize the elastic function of the elastic piece 20, but the elastic piece 20 is simply inclined to the opposite side to the locking projection 16 It is not limited to the one formed, but as shown in FIG. 5, the bent portion 44 may be formed at the center portion to increase elasticity, or the sliding portion 46 may be formed at the tip thereof as shown in FIG. As shown in FIG. 7, at the tip of the elastic piece 20 By forming the portion 47, it may be possible to reduce the frictional force of the elastic piece 20 which is slightly increased during the rotation of the locking member (1). Further, the lower side of the inner groove 50, the release projection 18 It is good to dig up to location.
