제1도는 본 고안의 요부 사시도.1 is a perspective view of main parts of the present invention.
제2도 a, b는 본 고안의 작용 상태를 나타낸 단면도.2 is a cross-sectional view showing an operating state of the present invention.
제3도는 종래 도어 개폐 장치의 부분 단면도.3 is a partial cross-sectional view of a conventional door opening and closing device.
본 고안은 VCR나 TV수강기등의 가전제품의 전면에 설치하는 도어 개폐장치에 관한 것으로 도어가 축지된 축에 기어를 축설하고 이 기어와 맞물리는 기어 일측에 타원형의 캠을 함께 축설하여 캠의 외면에는 캠의 형상과 동일하게 판 스프링을 설치하여 도어가 개폐될때 캠의 회전에 따라 캠은 판스프링을 접동하게 되어 판스프링의 탄력작용에 따라 도어의 개폐가 완만하고 정확하게 동작되도록한 도어 개폐 장치에 관한 것이다.The present invention relates to a door opening and closing device installed on the front of home appliances such as a VCR or TV receiver. The gear is laid on the shaft where the door is stored, and the elliptical cam is placed on one side of the gear meshing with the gear. The door opening and closing device is installed on the outer surface of the cam spring in the same shape as the cam to open and close the door spring according to the rotation of the cam when the door is opened and closed. It is about.
종래의 TCR나 TV수상기등의 가전제품 전면에 형성된 도어는 제3도에 도시된 바와같이 기기판넬(30)에 축(31)으로 축지된 도어(32) 내면의 걸림고리(33)는 판넬에 형성된 걸림돌기(34)에 끼워져서 도어(32)가 닫히도록 하고 열때에는 손으로 도어(32)를 잡아 당겨서 열리게 하였다.As shown in FIG. 3, the door formed on the front surface of a home appliance such as a conventional TCR or TV receiver has a hook 33 on the inner surface of the door 32, which is held by the shaft 31 on the device panel 30, on the panel. The door 32 is closed by being inserted into the formed locking protrusion 34, and when the door 32 is opened, the door 32 is pulled open by hand.
이와같이 도어(32)가 개폐될때 걸림고리(33)가 걸림돌기(34)에서 빠지면 도어(32)는 자유 회전 하기 때문에 도어의 자중에 의하여 도어가 급격하게 회전하여 개방되던가 또는 회전이 잘 안 되어서 도어(32)의 개폐가 순조롭지 않는 결점이 있었다.In this way, when the door 32 is opened and closed, if the locking ring 33 is pulled out of the locking protrusion 34, the door 32 rotates freely. There was a defect that opening and closing of (32) was not smooth.
본 고안은 이와같은 결점을 해결하기 위하여 가전제품의 전면에 설치하는 도어의 지지축에 캠과 판스프링을 결합하여 도어개폐시에 판스프링의 탄성력을 가하여 개폐 작용이 정확하고 도어개폐가 원할하고 취급에 편리하도록하여 품질을 높이는데 그 목적이 있는 것이다.The present invention combines the cam and the leaf spring on the support shaft of the door installed on the front of the home appliance to solve the above-mentioned defects, and applies the elastic force of the leaf spring to open and close the door. The purpose is to increase the quality by making it convenient.
본 고안의 구성과 작용효과를 도면 참조하면서 상세하게 설명하면 다음과 같다. 제1도에 의하여 본 고안의 구성은, 도어(1)내면 하측에 돌출된 기어(2)는 기기판넬(3)에 축(4)으로 축지되고 기기판넬(3)에 고정된축(5)에 끼워진 구동기어(6)는 기어(2)와 맞물리고 구동기어(6)와 일체로된 타원형 캠(7)의 주위면상에 판스프링(8)을 위치시켜서 양단을 기기판넬(3)에 형성된 상하의 홈(9, 9')에 끼워서 된 것이다.Referring to the configuration and effect of the present invention in detail with reference to the drawings as follows. According to the configuration of the present invention according to Figure 1, the gear (2) protruding below the inner surface of the door (1) is supported by the shaft (4) on the instrument panel 3 and fixed to the instrument panel (3) The drive gear 6 fitted to the gear 2 engages with the gear 2 and positions the leaf spring 8 on the circumferential surface of the elliptical cam 7 integrated with the drive gear 6 so that both ends are formed on the machine panel 3. It fits into the upper and lower grooves 9 and 9 '.
이와같이 구성된 본 고안의 작용효과를 설명하면 제2도 a와 같이 도어(1)의 일측변부를 잡고 잡아 당기면 도어(1)가 닫힌 상태로 부터 45°정도까지 회전할때는 탄성력은 점점커지게 된다. 즉 도어(1)가 열리면 기어(2)는 축(4)을 중심으로 반시계방향으로 회전한다. 따라서 기어(2)와 맞물린 구동기어(6)와 타원형 캠(7)은 시계 방향으로 회전하게 된다. 이때 타원형 캠(7)은 양측에서 타원 지지되어 있던 판스프링(8)을 양측옆으로 벌어지게 한다.Referring to the operation and effect of the present invention configured as described above, as shown in Figure 2 a and pulls on one side of the door (1) and pulls the elastic force is gradually increased when the door 1 is rotated to about 45 ° from the closed state. That is, when the door 1 is opened, the gear 2 rotates counterclockwise about the shaft 4. Therefore, the drive gear 6 and the elliptical cam 7 meshed with the gear 2 rotate in a clockwise direction. At this time, the elliptical cam 7 opens the leaf spring 8 which is elliptically supported on both sides.
도어(1)를 회전하여 45°를 지나서 회전하면 이때는 손을 놓아도 판스프링(8)은 자체 탄성력에 의하여 원상복귀되고 타원형 캠(7)은 동일 방향의 시계방향으로 급격하게 자동 회전 되므로 제2도 b와 같이 도어(1)는 90°까지 개방되는 것이다.When the door 1 is rotated and rotated past 45 °, the leaf spring 8 returns to its original position by its elastic force and the elliptical cam 7 rotates rapidly in the clockwise direction in the same direction. As shown in b, the door 1 is opened to 90 degrees.
그리고 도어(1)를 닫을때에는 손으로 도어를 밀어 붙이면 된다.When the door 1 is closed, the door may be pushed by hand.
이때에도 도어(1)가 회전되어 45°가 넘으면 도어가 급격하게 회전되어 도어는 닫히게 된다.In this case, when the door 1 is rotated and exceeds 45 °, the door is rapidly rotated to close the door.
즉 제2도 나의 상태에서 도어(1)를 밀어 붙이면 기어(2)는 시계방향으로 구동기어(6)는 캠(7)과 같이 반시계 방향으로 회전된다. 이때 타원형 캠(7)은 판스프링(8)을 양측으로 밀면서 회전하게 되므로 판스프링(8)의 탄력을 받아서 완만하고 정확하게 닫히게 된다. 그리고 캠(7)과 판스프링(8)은 원상 복귀된다.That is, when the door 1 is pushed in the state of FIG. 2, the gear 2 is rotated clockwise and the drive gear 6 is rotated counterclockwise like the cam 7. At this time, the elliptical cam (7) is rotated while pushing the leaf spring (8) to both sides is received smoothly and accurately closed by the elasticity of the leaf spring (8). The cam 7 and the leaf spring 8 are returned to their original shape.
이와 같이 본 고안은 구성 부품들의 기계적 강도가 견고하여 장기간 사용할 수 있고 도어 개폐의 취급이 편리하고 실용성을 높이게 한 것이다.As such, the present invention is to make the mechanical strength of the components strong, so that it can be used for a long time, and the handling of door opening and closing is enhanced and practical.
