Description

폴딩도어용 열교방지 창호프레임{Thermal Bridge Reduced Window Frame for Folding door}Thermal Bridge Reduced Window Frame for Folding door}

본 발명은 폴딩도어의 창호프레임 중에서 손잡이와 잠금장치가 장치되는 창호프레임에 관한 것으로, 더욱 상세하게는 창호프레임에 내장된 금속소재의 잠금장치 부품에 의해 열교현상이 일어나는 문제를 해결한 새로운 단열구조의 폴딩도어용 열교방지 창호프레임에 관한 것이다.The present invention relates to a window frame equipped with a handle and a locking device among the window frames of a folding door. It relates to a thermal bridge prevention window frame for folding doors.

폴딩도어(folding door)는 도 1과 같이 여러 개의 창호가 아코디언처럼 접히고 펼쳐지면서 열리고 닫히는 창호로, 설치된 벽면 전체를 오픈할 수 있어 공간의 개방성, 확장성, 활용성 등에서 높이 평가된다. 폴딩도어는 건물의 외벽체 대체용으로 주로 카페와 같은 상업적 공간에 사용되었으나, 최근에는 실내 칸막이용으로도 사용용도가 확대되어 주택, 사무실, 컨퍼런스홀 등에도 다양하게 사용되고 있다.A folding door is a window that opens and closes when several windows are folded and unfolded like an accordion as shown in FIG. 1, and the entire installed wall can be opened. Folding doors were mainly used in commercial spaces such as cafes as a replacement for exterior walls of buildings, but recently their use has been expanded to be used as interior partitions, and they are also used in various ways in houses, offices, conference halls, etc.

도 2는 종래 폴딩도어의 잠금구조를 보여준다. 보는 바와 같이 폴딩도어는 창호를 열고 닫기 위한 손잡이(H)가 장착되는 창호프레임(F2)의 경우 그 내부에 잠금장치(L1, L2)가 내장되어 손잡이(H)에 연동되는 구조로 마련된다. 손잡이(H)를 돌리면 잠금장치의 잠금구(L1)가 연동하여 승하강 동작함으로써 폴딩도어의 창틀프레임(F1)에 걸리거나 분리되어 폴딩도어의 잠금이 해제되거나 잠금되게 한 것이다. 보통 손잡이(H)는 창호프레임(F2) 외측 중간에 마련되고, 장금장치의 잠금구(L1)는 창호프레임(F2) 내부 상하단에 마련되고, 잠금장치의 록킹바(L2)가 창호프레임(F2) 내부에서 손잡이(H)와 잠금구(L1)를 연결하도록 마련되며, 이로써 손잡이(H)를 회동시키면 록킹바(L2)가 잠금구(L1)를 연동시켜 잠금구(L1)가 승하강 동작하게 된다.2 shows a locking structure of a conventional folding door. As can be seen, the folding door is provided in a structure linked to the handle (H) with built-in locking devices (L1, L2) in the case of the window frame (F2) on which the handle (H) for opening and closing the window is mounted. When the handle (H) is turned, the locking member (L1) of the locking device is interlocked to move up and down, so that it is caught on or separated from the window frame (F1) of the folding door so that the lock of the folding door is unlocked or locked. Usually, the handle (H) is provided in the middle of the outside of the window frame (F2), the locking device (L1) of the locking device is provided at the top and bottom inside the window frame (F2), and the locking bar (L2) of the locking device is the window frame (F2) ) is provided to connect the handle (H) and the locking member (L1) from the inside, whereby when the handle (H) is rotated, the locking bar (L2) interlocks the locking member (L1) and the locking member (L1) moves up and down will do

한편 창호프레임(F2)은 주로 금속 프로파일로 제작되는데, 금속소재만으로 이루어진 창호프레임(F2)은 열교현상으로 단열성능이 떨어지기 때문에 열교방지에 대한 고려가 필요하다. 열교방지를 위한 대표적인 방법으로는 금속 프로파일 중간이 분리되고 단열바로 연결되는 구조의 창호프레임(F2)이 있다. On the other hand, the window frame F2 is mainly made of a metal profile. Since the window frame F2 made of only a metal material has poor thermal insulation performance due to a thermal bridge phenomenon, it is necessary to consider the prevention of thermal bridge. A typical method for preventing thermal bridges is a window frame (F2) in which the middle of a metal profile is separated and connected to an insulating bar.

도 3(a)은 종래 많이 활용되는 폴딩도어용 창호프레임의 단면인데, 금속 프로파일이 한쌍의 프레임바(10a, 10b)로 마련되어 서로 이격 배치되고 그 사이가 한쌍의 단열바(20, 30)로 연결되는 구조를 가진다. 이러한 종래 폴딩도어용 창호프레임(F2)은 손잡이(H)가 설치되고 잠금장치(L1, L2)가 내장되는 위치에서도 동일하게 적용되는데, 그 결과 도 3(b)와 같은 구조가 된다. 도 3(b)에서와 같이 한쌍의 프레임바(10a, 10b)가 서로 이격 배치되면서 그 사이에 한쌍의 단열바(20, 30)가 설치되는 한편, 단열바(20) 외측으로 추가적으로 잠금장치의 록킹바(L2)가 더 설치된다. 한쌍의 프레임바(10a, 10b)가 록킹바(L2)에 의해 연결되는 구조가 되는 것이다. 그런데 록킹바(L2)는 한쌍의 프레임바(10a, 10b)와 마찬가지로 금속소재로 마련되기 때문에, 이를 통해 열교현상이 일어나므로 단열성능 떨어지는 원인이 된다.3 (a) is a cross-section of a window frame for a folding door that is widely used in the prior art. A metal profile is provided as a pair of frame bars 10a and 10b and spaced apart from each other, and the space between them is a pair of insulation bars 20 and 30. It has a connected structure. The conventional window frame (F2) for a folding door is equally applied at a position where the handle (H) is installed and the locking devices (L1, L2) are built-in, and as a result, the structure is as shown in FIG. 3(b). As shown in FIG. 3(b), a pair of frame bars 10a and 10b are spaced apart from each other, and a pair of heat insulating bars 20 and 30 are installed therebetween, while additionally, the locking device is provided to the outside of the heat insulating bar 20. A locking bar (L2) is further installed. A pair of frame bars (10a, 10b) is a structure that is connected by the locking bar (L2). However, since the locking bar L2 is made of a metal material like the pair of frame bars 10a and 10b, a thermal bridging phenomenon occurs through this, which causes deterioration in thermal insulation performance.

The present invention has been developed to improve the conventional window frame for folding doors, and to provide a thermal bridge prevention window frame for a folding door with a new heat insulation structure that can solve the problem of thermal bridge phenomenon caused by metal parts embedded in the window frame. There are technical challenges.

상기한 기술적 과제를 해결하기 위해 본 발명은, 폴딩도어용 창호프레임 중에서 손잡이와 잠금장치가 장치되는 위치의 창호프레임으로, 창짝이 설치되는 반대 위치에 개구부가 형성된 베이스프레임; 베이스프레임의 개구부에 홈-돌기 끼움결합으로 맞춤 설치되는 제1단열바;를 포함하여 구성되되, 제1단열바가 록킹바 수용부를 구비하도록 마련되어 손잡이와 잠금장치의 잠금구 사이를 연결하는 잠금장치의 록킹바가 록킹바 수용부에 수용된 채 손잡이에 연동하여 잠금구를 동작시키게 되는 것을 특징으로 하는 폴딩도어용 열교방지 창호프레임을 제공한다.In order to solve the above technical problem, the present invention provides a window frame at a position in which a handle and a locking device are installed among window frames for a folding door, comprising: a base frame having an opening formed at a position opposite to which a window leaf is installed; A first heat insulating bar fitted to the opening of the base frame by a groove-protrusion fitting coupling; the first heat insulating bar is provided to have a locking bar receiving part, and the locking device connects between the handle and the locking part of the locking device. It provides a window frame for preventing thermal bridges for folding doors, characterized in that the locking bar is interlocked with the handle while being accommodated in the locking bar receiving part to operate the locking tool.

본 발명에 따르면 다음과 같은 효과를 기대할 수 있다.According to the present invention, the following effects can be expected.

첫째, 손잡이와 잠금장치가 장치되는 폴딩도어용 창호프레임에서 잠금장치 부품을 단열바에 수용되게 함으로써 금속소재의 의한 창호프레임과 잠금장치 부품의 연속성을 차단하여 열교현상을 효과적으로 방지할 수 있다. 이로써 폴딩도어의 단열성능을 개선할 수 있다.First, it is possible to effectively prevent thermal bridging by blocking the continuity of the window frame and the locking device parts made of metal by allowing the locking device parts to be accommodated in the insulation bar in the window frame for the folding door equipped with the handle and the locking device. Accordingly, it is possible to improve the insulation performance of the folding door.

둘째, 기존 폴딩도어용 창호프레임의 설계변경 없이 단열바의 구조만을 간단히 변경시켜 적용할 수 있기 때문에, 적용성이 우수하다.Second, since it can be applied by simply changing the structure of the insulation bar without changing the design of the existing window frame for folding doors, the applicability is excellent.

이하, 첨부한 도면 및 바람직한 실시예에 따라 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail according to the accompanying drawings and preferred embodiments.

도 4는 본 발명에 따른 폴딩도어용 창호프레임의 단면도로, 본 발명은 폴딩도어용 창호프레임 중에서 손잡이(H)와 잠금장치(L1, L2)가 장치되는 위치의 창호프레임에 관한 것이다. 잠금장치(L1, L2)는 도 3에서와 같이 잠금구(L1)와 록킹바(L2)로 마련된다. 4 is a cross-sectional view of a window frame for a folding door according to the present invention, and the present invention relates to a window frame at a position in which a handle (H) and locking devices (L1, L2) are installed among the window frames for a folding door. The locking devices L1 and L2 are provided with a locking member L1 and a locking bar L2 as shown in FIG. 3 .

창호프레임에는 건물 개구부에 맞춤 설치되는 창틀프레임(F1)과 창틀프레임의 레일에 맞춤 설치되는 창짝프레임(F2)이 있는데, 본 발명은 창짝(W)이 설치되는 창짝프레임(F2) 중에서도 특히 손잡이(H)와 잠금장치(L1, L2)가 설치되는 위치의 창짝프레임을 대상으로 한다.The window frame includes a window frame frame (F1) that is custom installed in the building opening and a window frame frame (F2) that is custom installed on the rail of the window frame frame. H) and locking devices (L1, L2) are installed on the window frame.

본 발명에 따른 폴딩도어용 창호프레임(F2)은, 베이스프레임(10)과 제1단열바(20)를 포함하여 구성되며, 특히 제1단열바(20)에 록킹바 수용부(21)가 구비되어 잠금장치의 록킹바(L1)를 제1단열바의 록킹바 수용부(21)에 수용되게 함으로써 록킹바(L2)를 통한 열교현상이 일어나지 않게 한다는데 특징이 있다.The window frame (F2) for a folding door according to the present invention is configured to include a base frame (10) and a first insulating bar (20), and in particular, the locking bar receiving part (21) is provided in the first insulating bar (20). It is characterized in that the locking bar (L1) of the locking device is accommodated in the locking bar receiving portion 21 of the first insulating bar, thereby preventing the thermal bridge phenomenon from occurring through the locking bar (L2).

본 발명에서 베이스프레임(10)은 창짝이 설치되는 반대 위치에 개구부(11)가 형성되는 열린 단면의 프레임이다. 베이스프레임의 개구부(11)는 제1단열바(20) 내지 제2단열바(30)가 설치되는 공간이 되며, 그 결과 금속소재의 연속성이 차단되어 열교현상을 방지하는 역할을 한다. 도 4에서는 한쌍의 프레임바(10a, 10b)가 서로 이격 배치됨으로써 개구부(11)가 자연스럽게 형성되는 베이스프레임(10)을 예시하여 보여준다. 이러한 베이스프레임(10)에는 개구부(11) 내측에 창짝(W)이 끼움되어 밀착 설치되고, 개구부(11) 외측에 제1단열바(20) 내지 제2단열바(30)가 설치된다.In the present invention, the base frame 10 is an open cross-section frame in which an opening 11 is formed at a position opposite to which a window is installed. The opening 11 of the base frame serves as a space in which the first heat insulating bar 20 to the second heat insulating bar 30 are installed, and as a result, the continuity of the metal material is blocked to prevent a thermal bridge phenomenon. 4 exemplarily shows the base frame 10 in which the opening 11 is naturally formed by the pair of frame bars 10a and 10b being spaced apart from each other. In the base frame 10 , the windowpane W is fitted inside the opening 11 to be closely installed, and the first insulating bar 20 to the second insulating bar 30 are installed outside the opening 11 .

제1단열바(20)는 베이스프레임의 개구부(11)에 홈-돌기 끼움결합으로 맞춤 설치되는데, 특히 록킹바 수용부(21)를 구비하도록 마련된다. 록킹바 수용부(21)는 잠금장치의 잠금구(L1)와 손잡이(H) 사이를 연결하는 잠금장치의 록킹바(L2)가 수용되는 공간이다. 금속소재의 록킹바(L2)가 폴리아미드 등 단열소재의 제1단열바(20)에 수용되게 함으로써 록킹바(L2)에 의한 열교현상을 방지할 수 있다.The first insulating bar 20 is fitted to the opening 11 of the base frame by a groove-protrusion fitting, and in particular, it is provided to include a locking bar receiving part 21 . The locking bar receiving portion 21 is a space in which the locking bar (L2) of the locking device connecting between the locking device (L1) and the handle (H) of the locking device is accommodated. The thermal bridge phenomenon caused by the locking bar L2 can be prevented by allowing the metal locking bar L2 to be accommodated in the first heat insulating bar 20 made of an insulating material such as polyamide.

베이스프레임(10)이 한쌍의 프레임바(10a, 10b)로 마련된 경우에는 베이스프레임의 개구부(11) 중간에 제2단열바(30)가 홈-돌기 끼움결합으로 맞춤되게 더 설치될 수 있다. 이로써 서로 이격 배치되는 한쌍의 프레임바(10a, 10b)가 제1단열바(20)와 제2단열바(30)로 연결된다. 이 경우 제1단열바(20)와 제2단열바(30)는 한쌍의 프레임바 사이를 안정적으로 지지하면서 연결하도록 적절한 단면과 소재로 설계하여 적용한다.When the base frame 10 is provided with a pair of frame bars 10a and 10b, the second heat insulating bar 30 may be further installed in the middle of the opening 11 of the base frame to be fitted with groove-protrusion fitting. As a result, a pair of frame bars 10a and 10b spaced apart from each other are connected to each other by the first heat insulating bar 20 and the second heat insulating bar 30 . In this case, the first insulating bar 20 and the second insulating bar 30 are designed and applied with an appropriate cross section and material to stably support and connect between the pair of frame bars.

도 4는 결합홈(G1, G2)이 형성된 한쌍의 프레임바(10a, 10b)와 결합돌기(P1, P2)가 형성된 제1,2단열바(20)가 홈-돌기 끼움결합으로 완성되는 창호프레임(F1)을 예시하여 보여준다. 특히 도 4에서 제1단열바(20)는 가운데 보강된 웨브(20a)와 양쪽의 플랜지(20b)로 이루어진 ㄷ자 단면부재로 마련되고 있는데, 개구된 양쪽의 플랜지(20b) 사이가 록킹바 수용부(21)로 형성되고 있다. 이러한 제1단열바(20)는 양쪽의 플랜지(20b) 각각의 외측에 결합돌기(P1)가 형성되어 베이스프레임의 개구부(11) 외측 위치에 형성된 결합홈(G1)에 끼움 결합되고, 동시에 양쪽의 플랜지(20b) 각각의 내측에 가이드홈(22)이 형성되어 록킹바(L2)가 끼움결합되는 구조가 된다. 이에 따라 금속소재의 록킹바(L2)가 록킹바 수용부(21)에 수용되어 금속소재의 프레임바(10a, 10b)와 록킹바(L2) 사이에 단열소재의 제1단열바(20)가 위치하게 됨으로써 의한 열교현상이 방지되면서 단열성능을 확보하는 창호프레임으로 완성된다. 4 is a window in which a pair of frame bars 10a and 10b having coupling grooves G1 and G2 formed thereon and first and second heat insulating bars 20 having coupling protrusions P1 and P2 formed therein are completed by groove-protrusion fitting coupling. The frame F1 is shown by way of example. In particular, in FIG. 4, the first heat insulating bar 20 is provided as a U-shaped cross-sectional member consisting of a web 20a reinforced in the center and flanges 20b on both sides, and a locking bar receiving part is provided between the flanges 20b on both sides of the opening. (21) is formed. The first heat insulating bar 20 is fitted with a coupling protrusion P1 on the outside of each of the flanges 20b on both sides and is fitted into the coupling groove G1 formed outside the opening 11 of the base frame, and at the same time both sides A guide groove 22 is formed inside each of the flanges 20b of the locking bar L2 to have a structure in which the locking bar L2 is fitted.
