On the back surface of the first spring holder 73, as shown in Figs. 2 and 3, a second holder projection (73b) is formed in the projection guide groove 43, thereby forming a first spring holder 73 ) Is limited to move only within a predetermined interval inside the first link (40).
이러한 댐퍼유니트(70)의 구조에 의하여, 도어(D)의 개폐동작에 의하여 탑레버(20)가 움직이면 가이드롤(71)은 제1탑체결공(21)을 축으로 회동운동을 하고, 이에 따라 가이드롤(71)은 제1스프링홀더(73) 측으로 전진 또는 후진하게 된다. 이때 가이드롤(71)이 제1스프링홀더(73) 측으로 전진할 때, 가이드레일(72a)에 끼어진 홀더돌기(73a)는 스프링(75)의 탄성력을 극복하면서 제2스프링홀더(74) 측으로 이동하기 때문에, 제1스프링홀더(73)에는 전진을 방행하는 댐핑력이 인가되고, 이에 따라 탑레버(20)에는 댐핑력이 인가되어 도어(D)가 급격히 개폐되지 않도록 한다. By the structure of the damper unit 70, when the top lever 20 is moved by the opening and closing operation of the door (D), the guide roll 71 rotates about the first tower fastening hole 21, Accordingly, the guide roll 71 is moved forward or backward toward the first spring holder 73 side. At this time, when the guide roll 71 is advanced to the first spring holder 73 side, the holder projection (73a) sandwiched in the guide rail (72a) to the second spring holder 74 side while overcoming the elastic force of the spring (75) Since it moves, a damping force for advancing forward is applied to the first spring holder 73, and a damping force is applied to the top lever 20 so that the door D is not opened and closed abruptly.
다음, 상기한 다단링크 힌지장치의 동작을 설명한다. Next, the operation of the multi-stage link hinge device will be described.
도 4a 내지 도 4e 는 도 1의 다단링크 힌지장치의 작동관계를 설명하기 위한 도면이다. 4A to 4E are diagrams for describing an operation relationship of the multi-stage link hinge device of FIG. 1.
도 4a 에 도시된 바와 같이, 본체(B)의 우측에는 단턱(B1)이 형성되고, 단턱(B1) 좌측의 본체(B)에 도어(D)가 설치된다. 도어(D)가 본체(B)에 닫혀진 상태에서, 도어(D)의 표면은 단턱(B)의 상단 표면과 일치하고, 이때 버텀레버(10), 탑레버(20), 바디레버(30), 제1,2,3링크(40)(50)(60)가 상호 포개어진 상태가 된다. As shown in FIG. 4A, the step B1 is formed on the right side of the main body B, and the door D is installed on the main body B on the left side of the step B1. With the door D closed on the body B, the surface of the door D coincides with the top surface of the step B, wherein the bottom lever 10, the top lever 20, and the body lever 30 are closed. The first, second, and third links 40, 50, and 60 are in a superimposed state.
다음, 도어(D)를 개방하기 위하여 일측을 잡아당기면, 도 4b에 도시된 바와 같이, 바디레버(30)와 탑레버(20) 사이에 설치되는 제1,2링크(40)(50)에 의하여 도어(D)는 버텀레버(10)에 대하여 상승하고 한편으로 서서히 회동된다. Next, when one side is pulled to open the door D, as shown in FIG. 4B, the first and second links 40 and 50 are installed between the body lever 30 and the top lever 20. As a result, the door D is raised relative to the bottom lever 10 and gradually rotates.
다음, 도어(D)는 도 4c 내지 도 4e 에 도시된 일련의 과정을 통하여, 버텀레버(10)에서 더욱 상승하면서 큰 각도로 회동되여 본체(B)를 완전히 개방한다. Next, the door D is rotated at a large angle while being further lifted from the bottom lever 10 through a series of processes shown in FIGS. 4C to 4E to completely open the body B. FIG.
본 발명은 도면에 도시된 일 실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 본 기술 분야의 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
이와 같이, 본 발명의 다단 링크 힌지장치에 따르면, 도어(D)를 단턱(B1)이 있는 본체(B)에 설치하여 폐쇄하였을 때 도어(D)의 표면과 단턱(B1)의 상단 표면이 평행하게 할 수 있고, 이후 본체(B)를 개방하기 위하여 도어(D)를 잡아당길 때 도어(D)는 본체(B)에서 상승하면서 회동되므로 도어(D)가 단턱(B1)에 걸리지 않게 할 수 있다. 이에 따라 도어(D)의 회동공간을 줄일 수 있어 상대적으로 좁은 공간에 비치할 수 있는 대형 냉장고의 구현이 가능하다.As described above, according to the multi-stage link hinge device of the present invention, when the door D is installed on the main body B having the step B1 and closed, the surface of the door D and the top surface of the step B1 are parallel to each other. When the door D is then pulled to open the body B, the door D is rotated while being lifted from the body B so that the door D is not caught by the step B1. have. Accordingly, it is possible to reduce the rotation space of the door (D) it is possible to implement a large refrigerator that can be stored in a relatively narrow space.
또한 댐퍼유니트(70)가 일체화됨으로써, 도어(D)가 급격하게 개방되거나 폐쇄되지 않도록 하여, 충격에 의한 소음이나 손상을 방지할 수 있다. In addition, by integrating the damper unit 70, the door D is not opened or closed abruptly, and noise or damage due to an impact can be prevented.
