본 고안은 비디오 카세트 레코더의 제동장치에 관한 것으로, 특히 회전하는 릴의 제동시에 패드를 부착한브레이크에 미치는 집중하중에 따른 패드의 불균일한 마모와 변형에 의해 제동력의 불량과 제품자체의 작동이상을 방지하여 브레이크의 성능을 향상하도록 한 비디오 카세트 레코더의 제동장치에 관한 것이다.The present invention relates to a braking device for a video cassette recorder. In particular, the braking force and abnormal operation of the product itself are prevented due to uneven wear and deformation of the pad due to the concentrated load on the brake to which the pad is attached during braking of the reel. A braking device for a video cassette recorder which prevents and improves the performance of a brake.
종래의 장치는 브레이크의 기능을 하는 브라겟트에 평판형의 패드를 부착하여 회전하는 릴의 곡면과 접촉시키므로 릴의 회전운등이 제동되는 바, 제1도 내지 제2도는 종래장치의 구성과 작용을 보인 것으로 상기 평면의브라겟트(4) 일측에 소정두께를 가는 평판형 패드(2)가 부착된 브레이크부(3)를 축착하는 한편, 브라켓트(4)타측에 형성된 스프링고정구멍(7)과 스프링고정보스(9)를 스프링(8)으로 연결하며 스프링(8)의 신축에 의해브라겟트(4) 중심부에 결합된 중심보스(6)를 회전중심으로 회전운동을 하는 브레이크부(3)가 회전반경내에 설치되어 있는 릴(1)을 패드(2)의 접촉에 의하여 제동하도록 되어있으며, 걸림부(5')를 가지는 플레이트(5)가외력에 의하여 좌우로 작동되로록 설치되고 또한 걸림부(5')와 접촉되도록 브라켓트에 걸림보스(10)를 형성한구성으로 되어있다.The conventional apparatus attaches a flat pad to a bracket that functions as a brake and contacts the curved surface of the rotating reel, so that the rotation cloud of the reel is braked. FIGS. 1 to 2 show the configuration and function of the conventional apparatus. And a spring fixing hole 7 formed on the other side of the bracket 4 while compacting the brake portion 3 with the flat pad 2 having a predetermined thickness on one side of the flat bracket 4. The brake unit 3 which connects the spring high information 9 to the spring 8 and rotates the central boss 6 coupled to the center of the bracket 4 by the expansion and contraction of the spring 8 is rotated at the center of rotation. The reel 1 installed in the rotation radius is braked by the contact of the pad 2, and the plate 5 having the locking portion 5 'is installed to be operated left and right by external force and is also caught. The catching boss 10 is formed on the bracket to be in contact with the portion 5 '. It is a.
상기한 바와같이 구성된 종래의 장치는 제1도와 같이 브레이크부(3)가 릴(1)을 제동한 상태에서 외력에 의하여 플레이트(5)가 b방향으로 작동되면 걸림부(5')에 걸림보스(10)가 접촉되면서 브레이크부(3)는 중심보스(6)를 회전중심으로 하여 시계방향으로 회전하고 이 회전력은 스프링(8)에 인장력이 발생되도록 하며, 이때 릴(1)은 자유로운 회전운동을 하는 한편, 이와 반대로 외력에 의한 플레이트(5)가 a방향으로 작동되면 걸림부(5')가걸림보스(10)에서 이탈되고 스프링(8)에 작용하는 인장력이 복원되려는 힘에 의해 브레이크부(3)에 반시계방향의 회전력이 작용하면서 브레이크부(3)가 릴(1)의 표면에 접촉되어 릴(1)의 회전운동이 제공되는데, 이때브레이크부(3) 동작이 계속 반복되면 곡면의 릴(1)과 직접 접촉하는 평판형의 패드(2)에 집중하중이 작용하여제2도에 도시한 바와같이 패드(2)의 마모가 일어나면서 변형이 생기며 마모된 가루가 이물질이 되어 높은 정밀도를 요구하는 부품들 사이에 들어가 트러블을 야기시켜 작동이상 등의 문제들이 발생되며, 릴(1)과의 접촉상태가 약화되어 브레이크부(3)의 제동력이 저해되며, 브레이크부(3) 동작시 평판형의 패드(2)가 곡면의 릴(1)에 제대로 접촉되지 못한 경우에는 릴(1)의 회전방향으로 패드(2)가 밀리게 되면서 패드(2)가 탈락되거나 패드접착용 접착제가 흘러나와 브레이크부(3)에 부착된 패드(2)면을 오염시키게 되어 정확한 제동효과를 기대하기어려운 결함이 있다.In the conventional apparatus configured as described above, when the plate 5 is operated in the b direction by the external force while the brake unit 3 brakes the reel 1 as shown in FIG. As the 10 is in contact, the brake unit 3 rotates in the clockwise direction with the center boss 6 as the center of rotation, and this rotational force causes a tension force to be generated in the spring 8, wherein the reel 1 is free to rotate. On the other hand, when the plate 5 is operated in the a direction by the external force on the contrary, the brake portion 5 'is separated from the locking boss 10 and the brake portion is forced by the force to restore the tension force acting on the spring 8. Anti-clockwise rotational force acts on (3) and the brake part 3 comes into contact with the surface of the reel 1 to provide a rotational motion of the reel 1, in which case the curved part 3 continues to repeat the curved surface. The concentrated load acts on the flat pad 2 which is in direct contact with the reel 1 of the As shown in FIG. 2, the wear of the pad 2 occurs and deformation occurs, and the worn powder becomes a foreign material, causing trouble between the parts requiring high precision and causing problems such as malfunction. 1) the contact state is weakened and the braking force of the brake unit 3 is impaired. When the brake unit 3 is operated, the flat pad 2 does not properly contact the reel 1 of the curved surface. As the pad 2 is pushed in the rotational direction of 1), the pad 2 is dropped or the adhesive for pad adhesion flows out and contaminates the surface of the pad 2 attached to the brake unit 3, so that an accurate braking effect is expected. There is a difficult defect to do.
또한 종래에는 일본 공개실용신안공보 소53-27807호 및 평2-30132호와 같이 브레이크부와 패드를 원호형으로 형성한 것이 안출되어 있으나, 이러한 구성에서도 브레이크부와 패드가 단순히 평면적으로 접촉되는 것이므로 패드의 접착이 견고하게 이루어지지 않을 뿐만 아니라 패드를 정확한 위치로 접착하는데 어려움이 있는것이다.In addition, in the related art, it is conceived that the brake portion and the pad are formed in an arc shape as in Japanese Patent Application Laid-Open Publication No. 53-27807 and No. 2-30132, but in this configuration, the brake portion and the pad are simply in flat contact. Not only is the pad not firmly adhered to, but it is difficult to adhere the pad to the correct position.
본 고안은 이와같은 종래장치의 결함을 해소하기 위하여 안출한 것으로, 회전하는 릴에 직접 접촉하여 제동하는 브레이크부에 부착된 패드의 형상을 곡면으로 변형하여 불규칙적인 패드의 변형이나 부분적인 마모를 방지하고 패드의 초기에 요구된 성능이 그대로 유지될 수 있도록 함은 물론 패드의 접착이 견고하고 정확하게이루어질 수 있도록 한 것인바, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is devised to solve such a defect of the conventional device, and the shape of the pad attached to the brake portion braking in direct contact with the rotating reel is curved to prevent irregular deformation or partial wear of the pad. And to ensure that the performance required in the early days of the pad as it is to ensure that the adhesion of the pad can be made firm and accurate, as described in detail by the accompanying drawings as follows.
제3도 내지 제5도에 도시한 바와같이 릴(1)의 회전반경(R)과 같은 반경의 곡면이 형성된 브라켓트(14)의 내측에 회전반경(R')의 곡면을 가진 패드(12)를 부착하여 브레이크부(13)를 형성하고, 브라켓트(14)의 곡면 내측에 패드(l2)의 양단부가 접촉되도록 하기 위한 패드가이드(14a) 한쌍을 돌출시켜 형성하며, 패드(12)가부착된 부분인 브라켓트(14)에 접착홈(14b)을 형성하여서 된 것으로 도면에서 종래 구성과 동일한 부분에 대해서는 동일부호로 표시하였다.As shown in FIGS. 3 to 5, the pad 12 having the curved surface of the rotating radius R 'inside the bracket 14 having the curved surface having the same radius as the rotating radius R of the reel 1 is formed. To form a brake unit 13, and to protrude a pair of pad guides 14a for contacting both ends of the pad l2 to the inside of the curved surface of the bracket 14, and to which the pad 12 is attached. The adhesive groove 14b is formed in the bracket 14, which is a part, and the same parts as in the conventional configuration are denoted by the same reference numerals in the drawings.
상기한 바와같이 구성된 본 고안장치는 제3도에 도시한 바와 같이 릴(1)에서 브레이크부(13)가 이탈된 상태에서 a방향으로 플레이트(5)가 작동되면 걸림부(5')와 걸림보스(10)의 접촉상태가 해제되면서 스프링(8)에 작용하고 있는 인장력이 복원되려는 힘에 의해 브레이크부(13)에 반시계방향의 회전력이 작용하여 브레이크부(13)가 릴(1)의 표면에 접촉되어 릴(1)의 회전운동이 제동되며, 반대로 b방향으로 플레이트(f)가 이동하게 되면 브레이크부(13)의 제동력이 제거되어 릴(1)은 자유로운 회전동작을 하게된다.The device of the present invention configured as described above is engaged with the locking portion 5 'when the plate 5 is operated in the a direction in a state in which the brake portion 13 is separated from the reel 1 as shown in FIG. As the contact state of the boss 10 is released, a rotational force in the counterclockwise direction acts on the brake unit 13 by a force to restore the tension force acting on the spring 8, so that the brake unit 13 of the reel 1 The reel 1 is braked in contact with the surface. On the contrary, when the plate f moves in the b direction, the braking force of the brake unit 13 is removed and the reel 1 freely rotates.
이때, 릴(1)과 직접 접촉하는 브레이크부(13)에 부착된 패드(12)를 곡면형상으로 형성하고, 또한 릴(1)의반경(R)과 패드(12) 접촉면의 반경(R')을 동일하게 형성함으로서 브레이크부(13)의 패드(12)와 릴(1)의 접촉시 접촉면의 긴밀성으로 인한 패드(12)의 접촉면 전체에 균일한 제동력이 작용하므로 불규칙적인 패드(12)의변형이나 부분적인 패드(12)의 마모를 방지하여 제동효과를 향상시키며, 또한 제5도에 도시한 바와같이 패드(12)의 접착부인 브라켓트(14)에 접착홈(14b)을 형성하여 패드의 접착에 안정성을 부여하고 패드(12) 부착시에 부착위치가 정확하도록 패드가이드(14a)가 형성되어 있어 작업이 용이하다.At this time, the pad 12 attached to the brake unit 13 in direct contact with the reel 1 is formed in a curved shape, and the radius R of the reel 1 and the contact surface of the pad 12 are R '. By forming the same), uniform braking force is applied to the entire contact surface of the pad 12 due to the tightness of the contact surface when the pad 12 and the reel 1 of the brake unit 13 are in contact with each other. By preventing deformation or partial wear of the pad 12, the braking effect is improved, and as shown in FIG. 5, an adhesive groove 14b is formed in the bracket 14, which is an adhesive part of the pad 12, to form a pad. The pad guide 14a is formed so as to give stability to the adhesion and the attachment position is correct when the pad 12 is attached, so that the operation is easy.
