Description

미닫이 문의 닫힘 충격 완충장치{Closure of the shock absorber sliding doors}Closure of the shock absorber sliding doors

본 발명은 상단부에 호차가 부착되어 문틀 상단에 설치된 안내레일을 따라 가로방향으로 개폐되는 미닫이문의 닫힘 충격 완충장치에 대한 것이다.
The present invention relates to a closed shock absorber of a sliding door that is attached to the upper door and the door is opened and closed in the horizontal direction along the guide rail installed on the top of the door frame.

일반적으로 안내레일에 장치되어 가로방향으로 개폐되는 미닫이 문은 미닫이문 상단에 부착된 호차가 안내레일을 따라 이동하여 가로방향으로 개폐되므로 문이 닫힐 때 이동관성이 발생하고 이동된 문이 닫힘쪽 문틀에 부딪치게 되는 일이 발생하며 이때 문과 문틀 사이에 손이 끼이게 되면 심한 상처를 입게 되는 일이 빈번하기 때문에 미닫이 문이 닫힐 때 미닫이 문이 문틀 내면에서 심하게 부딪치는 것을 방지하기 위한 충격 완충장치가 설치되는 것이 보편화 되어 있다.In general, sliding doors that are installed in the guide rail and open and close in the horizontal direction are moved to the horizontal direction by moving the doorway attached to the top of the sliding door along the guide rail, so that when the door is closed, moving inertia occurs and the moved door is closed door frame When the hand is caught between the door and the door frame, it is often severely injured.Therefore, a shock absorber is installed to prevent the sliding door from hitting the inside of the door frame when the sliding door is closed. It is becoming commonplace.

그러나 종래의 닫침 충격 완충장치는 대부분이 코일스프링에 장진되는 완충재로 구성되어 부피가 크기 때문에 미닫이문을 안내하는 기존의 안내레일 속에 장치할 수가 없어 기존 안내레일의 길이 방향끝쪽에 완충장치를 수용할 수 있는 크기로 별도의 안내레일을 설치하고 완충기를 장치하는 구성이므로 시공이 까다롭고 재료비가 많이 들며 가격이 비싸게 될 뿐 아니라 가장 중요한 완충거리의 조정이 어렵게 되는 불편이 있었다.
However, since the conventional closing shock absorbers are mostly composed of cushioning material loaded on the coil spring, they cannot be installed in the existing guide rails for guiding the sliding doors because they are bulky, and thus the shock absorbers can be accommodated at the longitudinal ends of the existing guide rails. The installation of a separate guide rail and a shock absorber to a size that can be installed is difficult to construct, difficult to materialize, expensive and difficult to adjust the most important cushioning distance.

본 발명은 상기와 같은 불편을 해소하기 위하여 개발된 것이다.
The present invention has been developed to solve the above inconvenience.

본 발명은 미닫이 문이 장치되는 문틀 상단에 부착되어 미닫이 문 상단의 호차가 결합되어 미닫이문의 가로방향 개폐를 안내하는 안내레일과 안내레일을 따라 개폐되는 미닫이문의 닫힘쪽 안내레일속에 장치되어 미닫이 문이 닫힐 때 닫힘쪽 문틀에 접근하는 미닫이 문의 이동속도를 랙과 피니언이 결합하여 감소시키고 유체압에 의하여 작동하는 완충봉이 충격을 완화시켜 닫힘 충격을 완충시킬 수 있게 구성함으로써 효과적인 완충이 달성되게 하고 특히 피니언의 크기를 조정하는 선택을 통해 완충거리의 미세한 조정까지 달성되게 한 것이다.
The present invention is attached to the top of the door frame is equipped with a sliding door is coupled to the door of the sliding door top guide rail guides the horizontal opening and closing of the sliding door and the sliding door is installed in the guide side of the sliding door opening and closing along the guide rail When the door is closed, the sliding speed of the sliding door approaching the closing door frame is reduced by the combination of the rack and pinion, and the buffer rod operated by the fluid pressure can be configured to mitigate the shock by cushioning the closing shock, especially the pinion. The choice to adjust the size of the microscopy allows for a fine adjustment of the cushioning distance.

이와 같이 된 본 발명은 미닫이 문에 부착된 호차가 문틀 상단에 부착된 안내레일에 결합되어 개폐방향으로 이동을 하게 되는데 문을 닫기 위해 사람이 미닫이 문을 닫히는 쪽으로 밀게 되면, 미닫이 문이 닫히는 방향으로 이동하여 문틀 가까이 접근하면 미닫이문 호차에 장치된 랙의 접촉헤드가 먼저 피니언의 접촉돌기에 닿아 피니언을 회전시키고 피니언이 회전하면 랙의 접촉헤드를 절개홈부(50c)에 투입되며, 피니언과 완충구 본체 사이에 장치된 코일스프링의 견인 자세가 랙을 끌어당기는 방향으로 피니언 구동시킬 수 있게 가변되어 스프링의 힘으로 피니언을 회전시키게 되고, 피니언의 기어가 랙의 기어에 접촉하여 회전하므로 피니언이 랙을 당겨 문틀쪽으로 이동시키기 때문에 미닫이문의 이동이 제어되고 이어서 랙의 선단접촉헤드가 완충구 본체에 장치된 완충봉의 선단에 접촉하므로 완충봉에 작용하는 코일스프링의 반발력을 눌러 완충실 속으로 진입시키기 때문에 완충이 되면서 미닫이문의 닫힘이 이루어져 미닫이문이 살며시 닫히게 되는 작용이 이루어지는 것이다.The present invention as described above is coupled to the guide rail attached to the sliding door door is moved in the opening and closing direction when a person pushes toward the closing door to close the door, the sliding door in the direction of closing When moving closer to the door frame, the contact head of the rack mounted on the sliding door door first touches the contact projection of the pinion to rotate the pinion, and when the pinion rotates, the contact head of the rack is inserted into the incision groove 50c. The traction posture of the coil springs installed between the main bodies is variable so that the pinion can be driven in the direction of pulling the rack to rotate the pinion by the force of the spring, and the pinion rotates in contact with the gear of the rack. As it is pulled toward the door frame, the movement of the sliding door is controlled, and the front contact head of the rack Since it contacts the tip of the buffer rod installed in the old body, it pushes the repulsive force of the coil spring acting on the buffer rod to enter the buffer chamber, so that the sliding door is closed and the sliding door closes gently.

한편, 본 발명의 완충장치는 연결편 끝에 부착된 피니언이 지지축에 지지되어 제자리 회전하면서 피니언 회전축 외주면 일측에 돌출된 고정돌기와 완충구 본체의 연결편 사이에 코일스프링에 장진되어 피니언에 탄력을 부여하게 되며, 미닫이문이 닫힐 즈음에는 스프링이 피니언을 구동시켜 랙을 문틀쪽으로 이동시키는 힘이 작용하고 문이 완전히 닫히면 스프링은 최대로 수축된 상태가 되어 문열림에 대비하게 되며, 미닫이문을 열기 위해 사람의 힘으로 미닫이문을 열리는 방향으로 이동시키면 랙이 이동하면서 피니언이 역회전 되어 지지돌기(50e)가 외향하므로 코일스프링의 설치 상태가 코일스프링이 늘어나는 자세로 바뀌게 되고 탄력이 충진되며 랙의 선단 접촉헤드가 완충봉과 이완되어 완충봉에 가해지는 미닫이문의 압력이 해제되므로 코일스프링(50f)의 복원력에 의거 완충봉은 완충실에서 외향하여 원위치로 유지되므로 미닫이문이 닫힐 때에 대비하도록 되어 미닫이문이 닫힐때 충격완충이 이루어지는 것이다.On the other hand, the shock absorber of the present invention is supported by the pinion attached to the end of the connecting piece is rotated in place while being pinned to the coil spring between the fixing projection projecting on one side of the outer peripheral surface of the pinion rotation shaft and the connection port of the shock absorber body to give elasticity to the pinion. When the sliding door is closed, the spring drives the pinion to move the rack toward the door frame, and when the door is completely closed, the spring is fully retracted to prepare for the door opening. If the sliding door is moved in the open direction by the force, the rack moves and the pinion is reversely rotated so that the support protrusion (50e) is outward. Therefore, the installation state of the coil spring is changed to the posture in which the coil spring is extended and the elastic contact is filled. Is released from the shock absorbing rod to release the pressure of the sliding door Based on the restoring force of the spring 50f, the shock absorbing rod is kept out of the buffer chamber in the original position so that the shock absorbing shock is made when the sliding door is closed.

그리고 본 발명의 완충장치는 피니언의 직경을 크게하거나 적게하는 선택을 통해 랙을 이동시키는 거리를 조정할 수 있어서 완충에 필요한 거리를 미세하게 조정할 수 있는 특징을 가지게 되어 적절한 완충을 유도할 수 있게 되는 효과가 있고, 또 안내레일 속에 완충구 본체가 내장되므로 기존 안내레일을 그대로 이용할 수 있게 되어 시공이 편리하고 외관이 깔끔하며 안내레일과의 결합은 고정판(6)과 체결볼트(7)에 의하여 이루어지므로 별도의 안내레일 설치가 필요 없게 되어 비용부담이 저렴한 완충장치를 얻을 수 있도록 되는 이점이 있게 된다.
And the shock absorber of the present invention can adjust the distance to move the rack through the selection to increase or decrease the diameter of the pinion has a feature that can finely adjust the distance required for the buffer effect to induce the appropriate buffer In addition, since the shock absorber body is built in the guide rail, the existing guide rail can be used as it is, so construction is convenient, the appearance is clean, and the coupling with the guide rail is made by the fixing plate 6 and the fastening bolt 7. There is no need to install a separate guide rail has the advantage of being able to obtain a low-cost shock absorber.
