미닫이 도어의 완충장치{damping structure of sliding door}Damping structure of sliding doors

본 발명은 미닫이 도어에 관한 것으로, 보다 상세하게는 도어의 폐쇄시 결속부재가 가압돌부를 결속하여 도어가 완충실린어의 타측으로 개방되는 현상을 방지하면서 결속부재에 가해지는 가압력을 완충실린더의 작동으로 완충시키고, 도어의 개방시 가압돌부가 결속부재와 일정거리 이동하면서 도어를 서서히 개방시키며 결속부재가 회동하여 결속부재의 결속을 해제하면 도어가 자유롭게 개방되도록 하여 도어의 원활한 개폐가 가능한 미닫이 도어의 완충장치에 관한 것이다.The present invention relates to a sliding door, and more particularly, the operation of the shock absorbing cylinder is applied to the binding member while preventing the phenomenon in which the binding member binds the pressure protrusion when the door is closed, thereby preventing the door from opening to the other side of the buffer cylinder. Of the sliding door to open and close the door smoothly by opening the door while the pressing protrusion moves a certain distance with the binding member and releasing the binding member by rotating the binding member. It relates to a shock absorber.

일반적으로 미닫이 도어는 장롱이나 싱크대, 진열장, 신발장 또는 사무용 가구의 도어에 적용되는 것으로, 도어의 개폐공간을 최소화하므로 많이 사용되고 있는 실정이다.In general, the sliding door is applied to the door of the dresser or sink, showcase, shoe box or office furniture, it is a situation that is used a lot because it minimizes the opening and closing space of the door.

상기 미닫이 도어는 건물의 천정부에 가이드레일이 설치되고, 상기 가이드레일을 따라 도어를 안내하도록 도어의 상부에 로울러가 장착된 이동부재가 설치되어 도어를 좌,우로 이동하면서 내부공간을 개폐하는 것이다.The sliding door is a guide rail is installed on the ceiling of the building, and a moving member equipped with a roller is installed on the upper part of the door to guide the door along the guide rail to open and close the interior space while moving the door left and right.

그러나, 상기와 같은 미닫이 도어는 도어의 개폐시 도어의 단부가 문틀과 접촉되면서 충격에 의한 소음이 발생하게 되는 문제점이 있었다.However, the sliding door as described above has a problem in that noise due to impact occurs when the end of the door contacts the door frame when the door is opened or closed.

상기와 같은 문제점을 해결하기 위하여 최근에는 실용신안 제2006-10033호로 출원하여 제419941호로 등록받은 미닫이 도어용 완충구조가 제시된 바 있다.In order to solve the above problems, a buffer structure for a sliding door that has been recently applied and registered as Utility Model No. 2006-10033 and registered as No. 419941 has been proposed.

상기 선 등록 고안은, 도 1에 도시된 바와 같이, 저면 양측단에 일체로 고정편(11)을 구비하여 내부에 피스톤 통공(13)과 연결되는 작동공간부(12)를 갖는 본체(10)가 구비되고, 상기 작동공간부(12) 내에 유동 가능하게 설치되어 선단이 피스톤 통공(13)을 통해 외부로 노출되며 후단에 걸림프랜지(21)가 일체로 형성되는 봉상의 완충피스톤(20)이 구비되며, 일측단이 상기 완충피스톤(20)의 걸림프랜지(21)와 접촉되는 상태로 상기 작동공간부(12) 내에 설치되며 완충피스톤(20)에 돌출되는 방향으로의 탄성력을 부여하기 위한 탄발스프링(30)이 구비되고, 탄성적인 확장과 수축이 가능한 상태로 상기 본체(10)에 일체로 고정설치되며 선단 측에 홀딩요부(41)를 갖는 한 조의 탄성지지편(40)이 구비된다.The pre-registration design, as shown in Figure 1, the main body 10 having a working space portion 12 connected to the piston through-hole 13 therein with a fixed piece 11 integrally at both ends of the bottom surface therein; Is provided, the operating space portion 12 is installed so as to flow so that the front end is exposed to the outside through the piston through hole 13 and the rod-shaped buffer piston 20 is formed integrally at the rear end is It is provided, the one end is installed in the working space 12 in a state in contact with the engaging flange 21 of the buffer piston 20 and a bullet for imparting an elastic force in the direction protruding to the buffer piston (20) A spring 30 is provided, and a set of elastic support pieces 40 having a holding recess 41 on the tip side is provided integrally fixed to the main body 10 in a state in which elastic expansion and contraction are possible.

상기 도어(D)를 폐쇄하기 위해 내부공간이 개방되어 있던 도어(D)를 일측으로 이동하게 되면, 가이드봉(B)이 홀딩요부(41)를 외향으로 벌리면서 안으로 진입하게 됨과 동시에 상기 가이드봉(B)은 완충피스톤(20)의 선단과 접촉하게 되며, 이때 완충피스톤(20)은 도어(D)의 이동력에 의해 탄발스프링(30)을 수축시키면서 소음을 완화시키는 것이다.When the door D, which has been opened in order to close the door D, is moved to one side, the guide rod B enters the opening recess 41 toward the outside and enters the guide rod at the same time. (B) is in contact with the tip of the buffer piston 20, the buffer piston 20 is to mitigate the noise while contracting the ball spring 30 by the movement force of the door (D).

그러나, 상기 선 등록 고안은, 도어의 이동시 탄발스프링이 도어에 설치된 가이드봉을 지지하게 되므로 일시적으로 충격을 완화시키는 이점은 있으나, 도어의 장기간 사용시 탄성지지편 및 탄발스프링이 탄력을 상실하게 되므로 도어에 설치된 가이드봉이 홀딩요부 내부로 진입한 후 탄력이 저하된 탄성지지편 외부로 다시 이동하여 도어가 열리게 될 뿐만 아니라 충격을 원활하게 상쇄시키지 못하면서 소음을 발생하는 문제점이 있었다.However, the pre-registration scheme has the advantage of temporarily relieving impact because the ball springs support the guide rods installed in the doors when the door moves, but the elastic support pieces and the ball springs lose elasticity when the doors are used for a long time. After the guide rod installed in the holding recess enters the inside of the holding portion is moved back to the outside of the elastic support lowered elasticity, there was a problem that the noise is generated not only to open the door smoothly but also cancel the impact.

이에 본 발명은, 상술한 바와 같은 종래의 제반결함을 감안하여 이루어진 것으로, 본 발명의 목적은, 도어의 폐쇄시 결속부재가 회동하면서 가압돌부를 결속하므로 도어가 완충실린더의 타측으로 개방되는 현상을 방지할 뿐만 아니라 결속부재에 가해지는 가압력을 완충실린더의 작동으로 완충시키므로 충격 및 소음을 방지하고, 도어의 개방시 가압돌부가 결속부재와 일정거리 이동하면서 도어를 서서히 개방시키며 결속부재의 회동으로 가압돌부의 결속이 해제되면 도어가 자유롭게 개방되도록 하여 도어의 개폐를 원활하게 할 수 있는 미닫이 도어의 완충장치를 제공함에 있다.Accordingly, the present invention has been made in view of the above-described conventional defects, and an object of the present invention is to bind the pressure protrusion while the binding member rotates when the door is closed, thereby preventing the door from being opened to the other side of the buffer cylinder. Not only prevents the pressure applied to the binding member but also buffers the shock cylinder to prevent shock and noise.When the door is opened, the pressure protrusion moves to the binding member for a certain distance and gradually opens the door and presses it by the rotation of the binding member. When the binding of the protrusion is released to provide a shock absorbing device of the sliding door to open and close the door to freely open the door.
