건축용 여닫이형 도어의 처짐방지 구조{Protection Structure of Dropping of Swing Type Door for Construction}Protection Structure of Dropping of Swing Type Door for Construction}

본 발명은 여닫이형 도어가 자중에 의해 처지는 것을 방지하는데 이용하는 건축용 여닫이형 도어의 처짐방지 구조에 관한 것으로, 특히 도어 상단에 설치되는 롤러와 문틀 상단에 설치되는 롤러지지레일에 의해 도어가 닫힌 상태에서 경첩에 집중되었던 하중을 분산하여 지지하도록 함으로써 도어의 처짐을 방지할 수 있도록 한 건축용 여닫이형 도어의 처짐방지 구조에 관한 것이다.The present invention relates to a sag-proof structure of a sliding door type for building used to prevent sagging by the self-weight, in particular, in a state in which the door is closed by a roller installed on the top of the door and a roller support rail installed on the top of the door. The present invention relates to a deflection prevention structure of a building-type door that can prevent deflection of a door by distributing and supporting a load concentrated on a hinge.

일반적으로 건축물의 출입구에 시공되어 있는 여닫이형 도어는 밀거나 당기는 것에 의해 개폐되는 도어로서, 일측에 설치된 경첩을 중심으로 큰 원을 그리면서 회전되어 열리고 닫히게 되는데, 비교적 무거운 도어의 하중이 경첩에 외팔보 형태로 집중되기 때문에 시간이 경과될수록 도어가 약간씩 밑으로 처지면서 도어정의 맞물림을 부정확하게 하고 문틀과 도어의 틈새가 좁아져 도어의 개폐를 어렵게 하는 문제점이 있었다.In general, a sliding door that is constructed at the entrance of a building is a door that is opened or closed by pushing or pulling. The door is rotated to open and close by drawing a large circle around a hinge installed at one side, and the load of a relatively heavy door is cantilevered to the hinge. Because the concentration is concentrated in the form of the door over time, the door slightly sags downwards, and the engagement of the door is inaccurate, and the gap between the door frame and the door is narrowed, making it difficult to open and close the door.

이와 같은 일반적인 여닫이형 도어의 구조를 첨부도면 도1에 나타내었다. 이에 도시된 바와 같이 건축물의 출입구에 설치되어 있는 사각틀 형태의 문틀(11)에 도어(10)의 일측이 경첩(12)으로 연결되어 있었으며, 그 반대편에는 손잡이가 달린 도어정(13)이 설치되어 있었고, 도어정(13)으로부터 문틀(11)을 향해 출몰하는 도어래치(14)가 걸리는 걸림편(도시않됨)이 문틀(11)의 안쪽 측면에 설치되어 있었으며, 도어(10)와 문틀(11) 사이에는 도어(10)를 열고 닫을 때 간섭이 발생하지 않도록 약간의 틈이 형성되어 있었다.The structure of such a general sliding door is shown in FIG. As shown in this figure, one side of the door 10 was connected to the door frame 11 of the rectangular frame shape installed at the entrance of the building by a hinge 12, and a door tablet 13 having a handle is installed on the opposite side thereof. The latching piece (not shown) which catches the door latch 14 which hangs out from the door top 13 toward the door frame 11 was installed in the inner side of the door frame 11, and the door 10 and the door frame 11 were provided. There was a small gap between the doors 10 so as not to cause interference when the door 10 was opened and closed.

이러한 구조를 갖는 일반적인 여닫이형 도어는 건축물의 고급화 추세에 따라 그 무게가 점진적으로 무거워져 수십Kg 정도에 달하는 것도 일반화되어 있으며, 시공 초기에는 도어(10)와 문틀(11)이 일정한 간격으로 유지하지만 장기간 사용하게 되면, 무거운 도어(10)의 자중에 의해 경첩(12)의 반대편이 아래쪽으로 처지면서 문틀(11)과 도어(10)의 틈새를 변화시켜 도어(10)의 개폐를 어렵게 하거나 도어정(13)의 맞물림을 부정확하게 하여 도어(10)를 닫을 수 없게 되는 하자를 발생시키는 문제점이 있었다.The general door type door having such a structure is gradually weighted according to the trend of high-grade building, and it is also common to reach several tens of kilograms, and at the beginning of construction, the door 10 and the door frame 11 are maintained at regular intervals. In long-term use, the opposite side of the hinge 12 sags downward due to the weight of the heavy door 10, changing the gap between the door frame 11 and the door 10, making it difficult to open or close the door 10 or There was a problem in that the engagement of (13) was inaccurate, resulting in a defect that the door 10 could not be closed.

이와 같은 문제를 해소하기 위해 종래에는 출원번호 제20-2001-0038835호로 “여닫이문의 처짐방지구”가 개발 되었다. 이와 같은 종래기술은 문틀의 아래쪽 턱부위에 도어의 밑부분을 지지해 주는 롤러를 설치하여 도어가 닫혔을 때 도어의 밑부분을 지지하여 줌으로써 처짐을 방지하도록 되어 있었다.In order to solve such a problem, the conventional application number 20-2001-0038835 has been developed as "sag door hinges". This prior art was to prevent the deflection by supporting the bottom of the door when the door is closed by installing a roller for supporting the bottom of the door at the lower jaw of the door frame.

그러나, 이와 같은 종래기술은 도어의 밑부분이 롤러에 직접 접촉하는 구조로 되어 있었기 때문에 사용빈도가 높아지면서 도어의 아래쪽 모서리부분이 마모되면서 도어가 손상되는 문제점이 있었으며, 롤러의 높이만큼 문틀과 도어의 틈새를 크게 설정하여야 되기 때문에 미관상 보기에 좋지 않아 적용하기가 매우 곤란하였고, 롤러가 문틀의 아래쪽에 설치되어 있기 때문에 통행시 걸려서 넘어지는 문제점이 있었고, 아래쪽에 위치되어 있었기 때문에 쉽게 오염되는 문제점이 있었다.However, such a prior art has a problem that the lower part of the door is in direct contact with the roller because the lower portion of the door is worn out and the door is damaged, and the door frame and the door are as high as the roller. It was difficult to apply because it was not good for aesthetic view because it had to set a large gap of it, and there was a problem of falling when passing because of the roller installed at the bottom of the door frame, and it was easily contaminated because it was located at the bottom. there was.

또한, 롤러의 높이를 조절하기 위해 스페이서를 사용하고 있는데, 이는 롤러의 높이를 변경하는 경우 볼트를 풀고 분해한 상태에서 적합한 두께의 스페이서로 교환하여야 하기 때문에 사용이 매우 불편할 뿐만 아니라 높이조절이 연속적이지 않기 때문에 조절할 높이에 맞는 두께의 스페이서가 준비되지 않는 경우 높이 조절이 당장 어렵게 되는 문제점이 있었다.In addition, spacers are used to adjust the height of the roller, which is very inconvenient to use because the height of the roller must be replaced with a spacer of suitable thickness after loosening and disassembling the bolt. Since there is a problem that it is difficult to adjust the height if the spacer is not prepared for the height to adjust the height.

본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 여닫이형 도어의 처짐을 방지할 수 있는 것은 물론이고, 문틀과 도어의 틈새를 최소로 하는 것이 가능하며, 장기간 사용하여도 도어에 직접적인 손상을 주지 않고, 통행시 걸리거나 이물질에 의한 오염을 방지할 수 있으며, 롤러의 높이를 연속적으로 미세조절할 수 있는 건축용 여닫이형 도어의 처짐방지 구조를 제공함에 있다.The present invention has been made to solve the above problems, the purpose of which can prevent sagging of the swing-type door, as well as it is possible to minimize the gap between the door frame and the door, even in long-term use Without sacrificing direct damage, it is possible to prevent contamination by traffic jams or foreign matters, and to provide a structure for preventing sag of construction doors that can continuously finely adjust the height of rollers.

이하 본 발명에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도2 내지 도9에 도시된 바와 같이 도어(22)가 열린 상태에서 도어(22)를 닫게 되면, 도어(22)가 문틀(20)로 진입되는 과정에서 도어(22)에 설치되어 있는 롤러(60)가 롤러지지레일(30)의 수평궤도면(32)을 타고 구르게 된다.2 to 9, when the door 22 is closed while the door 22 is open, the door 22 is installed in the door 22 in the process of entering the door frame 20. The roller 60 is rolled on the horizontal track surface 32 of the roller support rail 30.

이때 수평궤도면(32)에 형성되어 있는 경사면(32a)(32b)은 롤러(60)가 수평궤도면(32)으로 부드럽게 진입되도록 하는 작용을 하게 되며, 도어(22)가 완전하게 닫혔을 때 롤러(60)가 롤러지지레일(30)의 수평궤도면(32) 위에 지지되기 때문에 도어(22)의 처짐을 방지할 수 있게 된다.At this time, the inclined surfaces 32a and 32b formed on the horizontal track surface 32 serve to smoothly enter the roller 60 into the horizontal track surface 32, and when the door 22 is completely closed. Since the roller 60 is supported on the horizontal track surface 32 of the roller support rail 30, sagging of the door 22 can be prevented.

한편, 롤러지지레일(30)과 브래킷(40)을 문틀(20)과 도어(22)에 각각 설치했을 때 시공오차에 의해 롤러(60)의 아래쪽 정점이 수평궤도면(32)보다 높거나 낮게 시공될 수 있는데 이때에는 L-렌치와 같은 공구를 이용해서 고정볼트(70)를 풀고 편심링(50)의 노출플랜지(52)에 형성되어 있는 높이조절드릴구멍(54)에 환봉을 끼운 다음 편심링(50)을 회전시키게 되면, 롤러(60)가 상하방향으로 움직이게 된다.On the other hand, when the roller support rail 30 and the bracket 40 are installed in the door frame 20 and the door 22, respectively, the lower apex of the roller 60 is higher or lower than the horizontal track surface 32 due to a construction error. In this case, using a tool such as an L-wrench, loosen the fixing bolt 70 and insert the round bar into the height adjusting drill hole 54 formed in the exposed flange 52 of the eccentric ring 50 and then the eccentric. When the ring 50 is rotated, the roller 60 moves up and down.

이와 같이 편심링(50)에 의해 롤러(60)의 높이를 조절한 다음 느슨하게 풀어져 있던 고정볼트(70)을 조이게 되면, 편심링(50)이 고정볼트(70)에 의해 롤러지지축(42)에 고정되어 회전할 수 없게 되고, 롤러(60)는 편심링(50)에서 자유롭게 회전된다.As such, when the height of the roller 60 is adjusted by the eccentric ring 50 and then the fixing bolt 70 is loosely tightened, the eccentric ring 50 is fixed by the fixing bolt 70 to the roller support shaft 42. The roller 60 is freely rotated in the eccentric ring 50 because it is fixed to and cannot rotate.

또, 롤러(60) 회전시 축방향으로 힘이 작용될 수 있게 되는데, 이때 롤러(60)가 고정볼트(70)의 볼트머리(72)에 의해 걸려서 축방향으로 이탈되는 것이 방지된다.In addition, the force can be applied in the axial direction during the rotation of the roller 60, wherein the roller 60 is prevented from being caught in the axial direction by being caught by the bolt head 72 of the fixing bolt 70.
