대한민국 특허출원 제2001-0086068호(2001년 12월 27일 출원)에 "냉장고용 힌지조립체"가 소개되어 있다.Republic of Korea Patent Application No. 2001-0086068 (filed December 27, 2001) "Hinge assembly for refrigerator" is introduced.

그러나, 상기 냉장고용 힌지조립체는 사용자가 원하는 도어의 개방상태를 유지시킬 수 있으나, 도어가 본체에 닫힌 상태에서 도어와 본체의 기밀을 계속해서 유지시킬 수 있도록 도어에 힘을 가하지 못하는 단점이 있다.However, the hinge assembly for a refrigerator can maintain the door open state desired by the user, but has a disadvantage in that a force cannot be applied to the door so that the door and the main body can be kept tight while the door is closed to the main body.

따라서, 본 발명의 목적은 캠부재의 노즈부 피크점이 사점(死點)으로 작용하도록 링크바아에 캠과 캠롤러를 각각 장착하여 캠롤러가 캠의 노즈부 피크점을 지나면 도어의 개방상태가 계속해서 유지되거나 닫힌상태에서 도어와 본체의 기밀이 유지되도록 도어에 힘을 가할 수 있는 다관절 힌지장치를 제공하는 것이다.Therefore, an object of the present invention is to mount the cam and the cam roller on the link bar so that the nose portion peak point of the cam member acts as the dead point, so that the open state of the door continues when the cam roller passes the nose portion peak point of the cam. It is to provide an articulated hinge device that can apply a force to the door to maintain the airtightness of the door and the main body in the state of being kept or closed.

상기와 같은 목적을 달성하기 위한 본 발명의 바람직한 실시예를 도면을 첨부하여 상세하게 설명하기로 한다.Exemplary embodiments of the present invention for achieving the above object will be described in detail with the accompanying drawings.

도 1을 참조하면, 본 발명에 따른 다관절 힌지장치(1)는 본체 브라켓(10)에 제 1 링크바아(L1)의 일단이 링크되고, 상기 제 1 링크바아(L1)의 타단에 제 2 링크바아(L2)의 일단이 링크되고, 상기 제 1 링크바아(L1)의 중간부분에 제 3 링크바아(L3)의 일단이 링크되고, 상기 제 2 및 제 3 링크바아(L2, L3)의 타단에 도어 브라켓(20)이 링크되고, 상기 본체 브라켓(10)과 제 3 링크바아(L3)의 중심이 제 4 링크바아(L4)에 의해 연결되고, 상기 도어 브라켓(20)에 캠레버(30)가 장착되고, 상기 캠레버(30)의 캠부재(40)와 캠롤러(50)가 밀착되도록 상기 캠롤러(50)가 제 2 링크바아(L2)에 형성된 V형 장착구멍(55)에 장착되고 상기 캠롤러(50)가 스프링(70)에 의해 지지된다.Referring to FIG. 1, in the articulated hinge device 1 according to the present invention, one end of a first link bar L1 is linked to a main body bracket 10, and a second end of the first link bar L1 is connected to a second end of the first link bar L1. One end of the link bar L2 is linked, one end of the third link bar L3 is linked to the middle portion of the first link bar L1, and the second and third link bars L2 and L3 are connected. The other end of the door bracket 20 is linked, the center of the body bracket 10 and the third link bar (L3) is connected by a fourth link bar (L4), the cam lever (20) to the door bracket (20) 30 is mounted and the V-shaped mounting hole 55 in which the cam roller 50 is formed in the second link bar L2 so that the cam member 40 and the cam roller 50 of the cam lever 30 come into close contact with each other. And the cam roller 50 is supported by the spring 70.

상기 캠부재(40)는 노즈부의 피크점(41)을 중심으로 닫힘곡선면(42)과 열림곡선면(43)이 형성되고, 상부핀(45)과 하부핀(46)에 의해 캠레버(30)에 고정된다.The cam member 40 has a closed curve surface 42 and an open curve surface 43 formed around the peak point 41 of the nose portion. The cam lever 40 is formed by the upper pin 45 and the lower pin 46. 30) is fixed.

상기 제 2 링크바아(L2)에 형성된 V형 장착구멍(55)은 급경사부(56)와 완경 사부(57)로 구분된다.The V-shaped mounting hole 55 formed in the second link bar L2 is divided into a steep slope 56 and a gentle slope 57.

상기와 같이 구성된 본 발명에 따른 다관절 힌지장치(1)가 붙박이 냉장고의 도어에 적용되는 예를 도 2를 참조하여 상세하게 설명하기로 한다.An example in which the articulated hinge device 1 according to the present invention configured as described above is applied to the door of the built-in refrigerator will be described in detail with reference to FIG. 2.

도어(80)가 닫혔을 때, 캠부재(40)의 닫힘곡선면(42)에 캠롤러(50)가 밀착되고, 압축된 스프링(70)의 탄성력이 캠롤러(50)를 통해 캠부재(40)의 닫힘곡선면(42)에 P벡터의 힘이 작용된다. 상기 P벡터를 분해하면, Y벡터의 힘이 도어브라켓(20)에 작용하여 상기 도어 브라켓(20)에 장착된 도어(80)의 후단부(81)에 Y벡터의 힘이 작용하게 되므로서, 도어(80)의 전단부(82)에 -Y벡터의 힘이 작용하여 도어(80)와 본체(85)의 기밀유지가 향상된다.When the door 80 is closed, the cam roller 50 is in close contact with the closing curved surface 42 of the cam member 40, the elastic force of the compressed spring 70 through the cam roller (50) The force of the P vector is applied to the closing curve 42 of 40. When the P vector is decomposed, the force of the Y vector acts on the door bracket 20 so that the force of the Y vector acts on the rear end 81 of the door 80 mounted on the door bracket 20. The force of the -Y vector acts on the front end 82 of the door 80 to improve the airtightness of the door 80 and the main body 85.

또한, 도 3a 및 도 3b, 도 1을 참조하면, 사용자가 도어(80)를 잡아당겨 도어가 개방될 때, 캠롤러(50)가 도 3a에서 도 3b를 통과하여 도 1로 이동된다. 즉, 캠롤러(50)가 캠부재(40)의 노즈부 피크점(41)을 통과하여 캠부재(40)의 열림곡선면(43)에 도달되고, 이후, 스프링(70)의 탄성력에 의해 캠롤러(50)가 V형 장착구멍(55)의 급경사부(56)를 따라 상승되면서, 캠롤러(50)가 캠부재(40)와 분리되어 캠레버(30)의 정지위치(31)까지 이동되므로서, 도어(80)의 개방상태가 계속해서 유지된다.3A, 3B, and 1, when the user pulls the door 80 and the door is opened, the cam roller 50 moves from FIG. 3A through FIG. 3B to FIG. 1. That is, the cam roller 50 passes through the nose part peak point 41 of the cam member 40 and reaches the opening curve surface 43 of the cam member 40, and then by the elastic force of the spring 70. As the cam roller 50 is raised along the steep inclined portion 56 of the V-shaped mounting hole 55, the cam roller 50 is separated from the cam member 40 to the stop position 31 of the cam lever 30. As it moves, the open state of the door 80 continues to be maintained.

이것은 캠부재(40)의 노즈부 피크점(41)이 사점으로 작용하고, 스프링(70)에 의해 캠롤러(50)가 지지되기 때문에 캠롤러(50)가 캠부재(40)의 열림곡선면(43)에 위치되면, 상기 캠롤러(50)가 계속해서 상기 캠부재(40)의 열림곡선면(43)에 위치하려는 성질을 이용한 것이다.This is because the nose roller peak point 41 of the cam member 40 acts as the dead point, and the cam roller 50 is supported by the spring 70 so that the cam roller 50 opens the curved surface of the cam member 40. If it is located at 43, the cam roller 50 continues to utilize the property of being positioned on the opening curve 43 of the cam member 40.

도어(80)를 닫을 경우에는 다관절 힌지장치의 작동이 위에서 설명한 것과 반대로 작동한다. 즉, 캠롤러(50)가 도 1에서 도 3a로 이동된 후, 도 2와 같이 캠부재(40)의 정지위치면(42)에 도달된다.When the door 80 is closed, the operation of the articulated hinge device is reversed from that described above. That is, after the cam roller 50 is moved from FIG. 1 to FIG. 3A, it reaches the stop position surface 42 of the cam member 40 like FIG.

본 발명에 따른 다관절 힌지장치에서, 각각의 링크바아(L1, L2, L3, L4)은 다음과 같이 작동한다.In the articulated hinge device according to the present invention, each link bar (L1, L2, L3, L4) operates as follows.

도 2에 도시된 바와같이, 도어(80)가 닫힌 상태에서 도 3a에 도시된 바와같이 도어(80)가 개방될 때, 도 3a에 도시된 바와같이, 제 1 링크바아(L1)가 회전축(P1)을 중심으로 화살표(90) 방향으로 회전한다. 즉, 제 4 링크바아(L4)의 제 2 회전축(P2)과 제 3 회전축(P3)의 높이가 같아질 때가지 제 1 링크바아(L1)가 회전축(P1)을 중심으로 화살표(90) 방향으로 회전한다. 이후, 도 3b에 도시된 바와같이 제 4 링크바아(L4)의 지지작용에 의해 제 2 링크바아(L2)와 제 3 링크바아(L3)가 세워지게 되므로서, 도어(80)가 개방될 때, 도어의 후단부(81)가 옆벽면(100)에 부딪치지 않게 된다. As shown in FIG. 2, when the door 80 is opened as shown in FIG. 3A with the door 80 closed, the first link bar L1 is rotated as shown in FIG. It rotates in the direction of the arrow 90 centering around P1). That is, the first link bar L1 moves in the direction of the arrow 90 about the rotation axis P1 until the heights of the second rotation axis P2 and the third rotation axis P3 of the fourth link bar L4 are the same. Rotate Thereafter, as shown in FIG. 3B, when the second link bar L2 and the third link bar L3 are erected by the supporting action of the fourth link bar L4, the door 80 is opened. The rear end 81 of the door does not hit the side wall surface 100.

위에서 설명한 본 발명에 따른 다관절 힌지장치는 본 발명의 사상을 설명하기 위한 것으로서, 본 발명은 여기에 한정되지 않으며, 다른 여러 분야에 적용할 수 있을 것이다.The articulated hinge device according to the present invention described above is for explaining the spirit of the present invention, and the present invention is not limited thereto and may be applied to various other fields.

위에서 설명한 바와같이, 본 발명에 따른 다관절 힌지장치는 캠부재의 노즈부 피크점이 사점(死點)으로 작용하도록 링크바아에 캠과 캠롤러를 각각 장착하여 캠롤러가 캠의 노즈부 피크점을 지나면 도어의 개방상태가 계속해서 유지되거나 닫 힌상태에서 도어와 본체의 기밀이 유지되도록 도어에 힘을 가할 수 있으며, 개어를 개폐할 때, 도어가 옆벽면에 부딪치지 않는 효과가 있다.As described above, in the articulated hinge apparatus according to the present invention, the cam and the cam rollers are respectively mounted on the link bar so that the nose portion peak points of the cam members act as dead points. When the door is kept open or closed, the door may be forced to maintain the airtightness of the door and the body, and when opening and closing the door, the door does not hit the side wall.
