For reference, Figure 8 is a front view showing such a conventional door and door frame.

이러한 종래의 출입문 조립체는 출입문(110)이 한 쌍의 힌지 (120, 상부 및 하부)를 매개로 문틀 (100) 에 회전 가능하게 설치되는 구조이므로, 설치가 비교적 용이하고 출입문(110)의 개폐도 용이하다.The conventional door assembly has a structure in which the door 110 is rotatably installed in the door frame 100 via a pair of hinges 120 (upper and lower), so that the door 110 is relatively easy to install and to open and close the door 110. It is easy.

주택의 현관문이나 사무실의 외부 출입문과 같이 출입문(110)의 일 측에서 타 측으로 연기 또는 불꽃의 이동을 확실히 차단할 필요가 있는 출입문 (예를 들어 방화문) 의 경우에는, 출입문 (110) 이 닫혔을 때 출입문 (110) 의 외측 테두리가 문틀 (100) 의 내측 테두리에 정확히 일치되도록 설치되어야 한다.In the case of a door (for example, a fire door) that needs to block the movement of smoke or sparks from one side of the door 110 to the other side, such as the front door of a house or the outside door of the office, the door 110 may be closed. When the outer edge of the door 110 should be installed so as to exactly match the inner edge of the door frame (100).

한편 아파트의 현관에는 중문이 설치되는 경우가 많은데 아파트 내부의 중문의 경우에는 여닫는 문짝이 2 개로 구성이 되는 경우에 1개의 문짝을 최대한 개방시킨 경우에도 개방된 부분의 공간이 비좁게 구성이 되는 문제점이 있다. 따라서 문짝을 3개로 구성이 되고, 문짝이 종래와 같이 여닫는 구성이 아니고 문짝과 문짝의 사이가 접히면서 열리는 구성이 되면 중문을 개방시킨 경우에 개방된 부분이 넓어지는 이점이 있게 된다.On the other hand, the front door of the apartment is often installed in the middle door, but in the case of the middle door inside the apartment is composed of two opening doors, even if one door is opened as much as possible the space of the open part is narrowly configured There is this. Therefore, when the door is composed of three, and the door is not a configuration that opens and closes as in the prior art, and the configuration is opened while folding between the door and the door has the advantage that the open part is widened when the middle door is opened.

다만, 접히면서 열리는 문짝의 경우에 문짝이 열리면서 닫히는 경우에 도어의 힌지가 단지 회전만 하도록 구성이 되어 각각의 문짝이 제대로 접히거나 펼쳐지지 않는 문제점이 있는 경우가 발생한다.However, in the case of a door that is opened while being folded, the door hinge is configured to only rotate when the door is opened and closed, which causes a problem that each door is not properly folded or unfolded.

상기 각각의 회전원통부 (23) 의 상부 및 하부에는 원형의 톱니바퀴 (1) 와 원통형의 톱니부 몸통 (3) 이 일체로 구성된 톱니부가 각각 삽입이 되고, 상기 각각의 회전원통부 (23) 와 고정되고,Upper and lower portions of each of the rotating cylindrical portions 23 are inserted into toothed portions, each of which is composed of a circular gear 1 and a cylindrical toothed body 3, and each of the rotating cylindrical portions 23. Is fixed with,

상기 각각의 톱니부의 몸통 (3) 은 각각의 회전원통부 (23) 에 삽입이 된 상태에서, 서로 마주보는 상기 각각의 톱니바퀴 (1) 는 톱니가 서로 맞물린 상태로 배치되고, 상기 톱니가 서로 맞물린 상태로 배치되는 톱니바퀴 (1) 들의 각각의 중심에는 중심구멍이 형성되어 있고, The body 3 of each toothed portion is inserted into each of the rotary cylinders 23, and the respective toothed wheels 1 facing each other are arranged with the teeth engaged with each other, and the teeth are mutually A center hole is formed in the center of each of the cog wheels 1 arranged in the engaged state,

상기 연결부 (25) 및 상기 연결부 (25) 에 각각 접하는 상기 회전원통부 (23) 가 서로 이탈되지 않도록, 안쪽 표면에 각각 돌출되게 구성된 한쌍의 톱니부지지봉 (15) 이 형성된 연결커버 (11) 가 상기 연결부 (25) 의 상부면과 하부면에 각각 고정되도록 설치되고, 상기 각각의 연결커버 (11) 의 안쪽 표면에 돌출되게 형성된 한쌍의 톱니부지지봉 (15) 은 각각의 톱니바퀴 (1) 의 중심구멍에 끼워지고, 상기 각각의 회전원통부 (23) 가 상기 톱니부지지봉 (15) 을 중심으로 회전하도록 구성되고, 상기 톱니바퀴 (1) 의 중앙부분의 안쪽으로는 볼베어링 (5) 과 스러스트 베어링 (7) 이 삽입되게 구성되는 것을 특징으로 한다. The connection cover 11 having a pair of toothed support rods 15 formed to protrude on an inner surface thereof is formed so that the connecting portion 25 and the rotating cylindrical portions 23 respectively contacting the connecting portion 25 are not separated from each other. The pair of toothed support rods 15 which are installed to be fixed to the upper and lower surfaces of the connecting portion 25 and protruded to the inner surface of the respective connecting cover 11 are formed of the respective gears 1. It is fitted in the center hole, and each said rotation cylinder part 23 is comprised so that it may rotate about the said tooth | gear support rod 15, The ball bearing 5 and thrust inside the center part of the said gear 1 are thrust. It is characterized in that the bearing 7 is configured to be inserted.

본 발명에 따른 톱니바퀴를 접목한 양방향 폴딩 도어용 힌지는 서로 연결되는 한쌍의 도어의 상단부와 하단부에 각각 기어가 장작되어 있는 도여용 힌지를 설치하여 서로 연결되는 한쌍의 도어가 열리거나 닫히는 경우에 각각의 도어가 회전하는 각도가 서로 일치되게 되어 도어의 개방과 폐쇄가 안정감을 가지고 이루어지는 현저한 특징이 있다.When the hinge for the bi-directional folding door grafting the gear according to the present invention is installed on the upper and lower ends of the pair of doors connected to each other, the donor hinges are geared in the case of opening or closing the pair of doors connected to each other The angle of rotation of each door is coincident with each other so that the opening and closing of the door have a sense of stability.

만일 도어의 힌지에서 내부에 톱니기어가 장착되지 있지 않는 경우에는 문을 열거나 닫는 경우에, 회전하는 한 쌍의 각각의 도어가 서로 독립적으로 회전을 하게되어 회전 각도가 불규칙적으로 되게 되어 사용자가 도어를 개폐할때 안정감이 떨어지는 문제점이 있다.If the gear is not installed inside the hinge of the door, when opening or closing the door, the rotating pair of doors rotate independently of each other and the rotation angle becomes irregular. There is a problem of falling stability when opening and closing.

또한, 사용자가 일반적인 여닫이 문을 닫는 행동으로 문을 닫을 때 서로 연결되는 도어들을 동시에 닫지 못하는 경우에 접이식 도어가 한번에 제대로 닫히지 못하는 경우도 발생할 수 있다. In addition, when the user does not close the doors connected to each other at the same time when the user closes the door by closing the general swing door may occur when the folding door is not properly closed at once.

그러나 본 발명에 따른 양방향 폴딩 도어용 힌지를 서로 인접하는 도어와 도어의 이음부분 사이에 장착하면, 상하부에 설치되는 2개의 힌지에 각각 한쌍의 기어가 장착(고정)되고 서로 기어가 맞물려 회전하게 되어, 각각의 도어의 힌지에 기어가 맞물려 같은 회전각으로 서로 인접하는 도어가 일정하게 회전하므로 문짝의 요동이 없어 안정감이 있고, 사용자가 일반적으로 여닫이문을 닫는 행동으로 문을 닫았을 때도 기어의 맞물림으로 회전한 2개 이상의 도어가 항상 일직선상에 있으므로 틈이 없이 완전히 닫히게 되는 현저한 효과가 있다.However, when the hinge for the bi-directional folding door according to the present invention is mounted between the adjacent doors and the joints of the doors, a pair of gears are mounted (fixed) on the two hinges installed at the upper and lower sides, respectively, and the gears rotate to mesh with each other. There is no swinging of the door because the gears are engaged with the hinge of each door and the doors are rotated at the same rotation angle constantly.Therefore, there is a sense of stability, and the gear is engaged even when the user normally closes the door by closing the door. As the two or more doors rotated are always in a straight line, there is a remarkable effect of being completely closed without any gap.
