Abstract

The present invention relates to a sliding door having a new structure capable of preventing a door panel from being separated from a door frame by an impact generated during opening and closing. The sliding door according to the present invention has an ascending and descending shaft (42) fixed not to descend if a lower side surface of a nut member (44) is lowered to adhere closely to the upper surface of a cylinder (41) by rotating the nut member (44) with a door panel (30) installed so that a combination part (42a) of the ascending and descending shaft (42) can be combined with an upper combination hole (21). Therefore, the door panel (30) does not ascend when a user opens or closes the door panel (30) by sliding the door panel in a lateral direction, so accordingly the door panel (30) can be prevented from ascending and being separated from the door frame (10) when opening or closing the door panel (30).

슬라이딩도어{sliding door}sliding door {sliding door}

본 발명은 개폐할 때 발생되는 충격에 의해 도어패널이 도어프레임으로부터 이탈되는 것을 방지할 수 있도록 된 새로운 구조의 슬라이딩도어에 관한 것이다.The present invention relates to a sliding door having a novel structure capable of preventing a door panel from being separated from a door frame due to an impact generated during opening and closing.

도 1 및 도 2는 일반적인 슬라이딩도어의 일예를 도시한 것으로, 사각형으로 구성된 도어프레임(10)과, 상기 도어프레임(10)의 상단에 측방향으로 슬라이드가능하게 결합되는 슬라이더(20)와, 하단은 상기 도어프레임(10)에 측방향으로 슬라이드가능하게 결합되고 상단에는 상기 슬라이더(20)에 탈착가능하게 결합되는 결합구(40)가 구비된 도어패널(30)로 구성된다.1 and 2 show an example of a general sliding door, a door frame 10 composed of a square, a slider 20 slidably coupled to the upper end of the door frame 10 in a lateral direction, and a lower end consists of a door panel 30 provided with a coupler 40 slidably coupled to the door frame 10 in a lateral direction and detachably coupled to the slider 20 at an upper end.

이때, 상기 도어프레임(10)의 내부 하측에는 측방향으로 연장된 가이드레일(11)이 구비된다.At this time, a guide rail 11 extending laterally is provided on the inner lower side of the door frame 10 .

그리고, 상기 도어패널(30)은 하단이 상기 가이드레일(11)에 슬라이드가능하게 결합된다.And, the lower end of the door panel 30 is slidably coupled to the guide rail 11 .

또한, 슬라이더(20)의 하측면에는 상부결합공(21)이 형성되고, 상기 도어패널(30)의 상면에는 하부결합공(31)이 형성된다.In addition, an upper coupling hole 21 is formed on the lower side of the slider 20, and a lower coupling hole 31 is formed on the upper side of the door panel 30.

상기 결합구(40)는 상하방향으로 연장된 통형상으로 구성되고 상단에 관통공(41a)이 형성되며 상단 둘레부에는 상기 도어패널(30)의 상면에 걸리는 걸림턱(41b)이 형성된 실린더(41)와, 상하방향으로 연장된 봉형상으로 구성되어 상기 관통공(41a)에 승강가능하게 결합되며 상단에는 상기 상부결합공(21)에 결합되는 결합부(42a)가 형성된 승강축(42)과, 상기 실린더(41)의 내부에 구비되며 상기 승강축(42)에 연결되어 승강축(42)을 상측으로 가압하는 탄성부재(43)로 구성된다.The coupler 40 is composed of a cylindrical shape extending in the vertical direction, a through hole 41a is formed at the upper end, and a locking jaw 41b that is caught on the upper surface of the door panel 30 is formed at the upper circumference of the cylinder ( 41), and a lift shaft 42 composed of a rod shape extending in the vertical direction, coupled to the through hole 41a to be liftable, and having a coupling part 42a coupled to the upper coupling hole 21 at the upper end. and an elastic member 43 provided inside the cylinder 41 and connected to the lifting shaft 42 to press the lifting shaft 42 upward.

따라서, 상기 결합구(40)가 상기 하부결합공(31)에 결합된 상태에서, 상기 승강축(42)의 상단이 상기 상부결합공(21)에 결합되고, 상기 도어패널(30)의 하단이 상기 도어프레임(10)에 결합되도록 함으로써, 슬라이딩도어를 상기 도어프레임(10)에 측방향으로 슬라이드가능하게 결합할 수 있다.Therefore, in a state in which the coupler 40 is coupled to the lower coupling hole 31, the upper end of the lifting shaft 42 is coupled to the upper coupling hole 21, and the lower end of the door panel 30 By coupling the sliding door to the door frame 10, the sliding door can be slidably coupled to the door frame 10 in the lateral direction.

이때, 상기 승강축(42)이 탄성부재(43)에 의해 상측으로 가압됨으로, 상기 승강축(42)의 상단이 상기 상부결합공(21)에 결합된 상태를 유지하여, 도어패널(30)을 측방향으로 슬라이드시키면 상기 슬라이더(20)가 도어패널(30)과 함께 측방향으로 슬라이드되면서 도어패널(30)의 상단을 지지하게 된다.At this time, since the lifting shaft 42 is pressed upward by the elastic member 43, the upper end of the lifting shaft 42 remains coupled to the upper coupling hole 21, and the door panel 30 When the is slid in the lateral direction, the slider 20 slides in the lateral direction together with the door panel 30 and supports the upper end of the door panel 30 .

그런데, 이러한 슬라이딩도어의 경우, 사용자가 도어패널(30)을 측방향으로 강하게 밀어 도어패널(30)이 도어프레임(10)에 충돌하거나, 도어패널(30)을 상측으로 당기면서 측방향으로 밀 경우, 순간적으로 도어패널(30)의 상측으로 들리면서 도어패널(30)이 도어프레임(10)으로부터 이탈되는 경우가 발생되었다.However, in the case of such a sliding door, the user strongly pushes the door panel 30 laterally so that the door panel 30 collides with the door frame 10 or pushes the door panel 30 upward while pulling it upward. In this case, a case occurred where the door panel 30 was separated from the door frame 10 while being momentarily lifted to the upper side of the door panel 30 .

따라서, 이러한 문제점을 해결할 수 있는 새로운 방법이 필요하게 되었다.Therefore, there is a need for a new method capable of solving these problems.

이하, 본 발명을 첨부된 예시도면에 의거하여 상세히 설명한다.Hereinafter, the present invention will be described in detail based on the accompanying exemplary drawings.

도 3 내지 도 5는 본 발명에 따른 슬라이딩도어를 도시한 것으로, 사각형으로 구성된 도어프레임(10)과, 상기 도어프레임(10)의 상단에 측방향으로 슬라이드가능하게 결합되는 슬라이더(20)와, 하단은 상기 도어프레임(10)의 하단에 측방향으로 슬라이드가능하게 결합되고 상단에는 상기 슬라이더(20)에 탈착가능하게 결합되는 결합구(40)가 구비된 도어패널(30)로 구성된 것은 종래와 동일하다.3 to 5 show a sliding door according to the present invention, a door frame 10 configured in a rectangular shape, a slider 20 slidably coupled to an upper end of the door frame 10 in a lateral direction, The lower end is slidably coupled to the lower end of the door frame 10 in the lateral direction, and the upper end is composed of a door panel 30 having a coupler 40 detachably coupled to the slider 20, unlike the prior art. same.

이때, 상기 슬라이더(20)의 하측면에는 상부결합공(21)이 형성되고, 상기 도어패널(30)의 상면에는 하부결합공(31)이 형성된다.At this time, an upper coupling hole 21 is formed on the lower side of the slider 20, and a lower coupling hole 31 is formed on the upper side of the door panel 30.

그리고, 상기 결합구(40)는 상하방향으로 연장된 통형상으로 구성되고 상단에 관통공(41a)이 형성되며 상단 둘레부에는 상기 도어패널(30)의 상면에 걸리는 걸림턱(41b)이 형성된 실린더(41)와, 상하방향으로 연장된 봉형상으로 구성되어 상기 관통공(41a)에 승강가능하게 결합되며 상단에는 상기 상부결합공(21)에 결합되는 결합부(42a)가 형성된 승강축(42)과, 상기 실린더(41)의 내부에 구비되며 상기 승강축(42)에 연결되어 승강축(42)을 상측으로 가압하는 탄성부재(43)로 구성된 것은 종래와 동일하다.Further, the coupler 40 is configured in a tubular shape extending in the vertical direction, a through hole 41a is formed at the upper end, and a locking jaw 41b that is caught on the upper surface of the door panel 30 is formed at the upper circumference. It consists of a cylinder 41 and a rod shape extending in the vertical direction, is coupled to the through hole 41a to be liftable, and has a coupling part 42a coupled to the upper coupling hole 21 at the upper end. 42) and an elastic member 43 provided inside the cylinder 41 and connected to the lifting shaft 42 to press the lifting shaft 42 upward is the same as in the prior art.

그리고, 본 발명에 따르면, 상기 승강축(42)의 둘레면에는 나사산이 형성된다.And, according to the present invention, a screw thread is formed on the circumferential surface of the lifting shaft 42 .

그리고, 상기 승강축(42)의 외측에는 너트부재(44)가 나사결합된다.Also, a nut member 44 is screwed to the outside of the lifting shaft 42 .

상기 너트부재(44)는 상기 승강축(42)의 나사산에 나사결합되어, 사용자가 정역방향으로 회전시키면 승강축(42)을 따라 승강되는 것으로, 승강축(42)이 하강될 때, 상기 실린더(41)의 상단에 걸려 승강축(42)이 하강되는 길이를 제한하도록 구성된다.The nut member 44 is screwed to the screw thread of the lifting shaft 42, and when the user rotates it in the forward and reverse direction, the nut member 44 is lifted along the lifting shaft 42, and when the lifting shaft 42 is lowered, the cylinder (41) is configured to limit the length of the lifting shaft (42) is lowered hanging over the upper end.

이때, 너트부재(44)의 풀림을 방지하기 위해, 상기 승강축(42)의 표면에는 테피론처리를 하는 것이 바람직하다.At this time, in order to prevent the loosening of the nut member 44, it is preferable to treat the surface of the lifting shaft 42 with Tepiron.

이와 같이 구성된 슬라이딩도어는 상기 승강축(42)의 결합부(42a)가 상기 상부결합공(21)에 결합되도록 도어패널(30)을 설치한 상태에서, 상기 너트부재(44)를 회전시켜 너트부재(44)의 하측면이 실린더(41)의 상면에 밀착되도록 하강시키면, 상기 승강축(42)이 하강되지 않도록 고정된다.In the sliding door configured as described above, the nut member 44 is rotated in a state in which the door panel 30 is installed so that the coupling part 42a of the lifting shaft 42 is coupled to the upper coupling hole 21, and the nut member 44 is rotated. When the lower surface of the member 44 is lowered so as to come into close contact with the upper surface of the cylinder 41, the lifting shaft 42 is fixed so as not to descend.

따라서, 사용자가 도어패널(30)을 측방향으로 슬라이드시켜 열거나 닫을 때, 도어패널(30)이 상승되지 않게 되며, 이에 따라, 도어패널(30)을 열거나 닫을 때 도어패널(30)이 상승되어 도어프레임(10)에서 이탈되는 것을 방지할 수 있다.Therefore, when the user opens or closes the door panel 30 by sliding it in the lateral direction, the door panel 30 does not rise, and thus, when the door panel 30 is opened or closed, the door panel 30 does not move. It can be prevented from being lifted and separated from the door frame 10 .
