본 발명은 실내도어의 충격흡수구조에 관한 것으로, 더욱 상세하게는 공압에 의한 충격흡수 구조로서, 건축물의 내부에 설치되어 있는 실내도어가 창을 통해 불어오는 바람이나, 사용자의 무리한 외력에 의해 닫혔을때 실내도어와 문틀과의 충격에 따른 실내도어의 수명단축과 충격음에 의해 사람들이 놀라는등을 방지할 수 있게 한 건축물 실내도어 충격흡수구조에 관한 것이다.The present invention relates to a shock absorbing structure of an indoor door, and more particularly, to a shock absorbing structure by pneumatic pressure, an indoor door installed inside a building is closed by a wind blowing through a window or an unreasonable external force of a user. The present invention relates to a shock absorbing structure of an indoor door that prevents people from being surprised by the shortening of the life of the indoor door and the impact sound caused by the impact between the indoor door and the door frame.

일반적으로 건축물의 내부에는 독립된 공간의 활용을 위해 거실과 방 또는 주방과 방의 경계를 이루는 도어가 설치되어 그 도어를 통해 출입 및 외부와 차단 할 수 있는 것이다.In general, the interior of the building is a door that forms the boundary between the living room and the room or the kitchen and the room is installed for the use of the independent space can be blocked from the entrance and the outside through the door.

이러한 종래의 도어를 살펴보면 도 1의 도시와 같이 벽체의 개구부에 수직틀(110)과 수평틀(120)로 이루어진 중앙이 개구된 직사각체상의 문틀(100)이 형성되며, 상기 문틀(100)의 일측수직틀(110) 내측에는 도어(200)가 경첩결합되어 개폐가능하게 구성된 것으로, 사용자는 도어의 개폐에 의해 사용자의 출입 및 외부와의 차단이 가능한 것이다.Referring to the conventional door as shown in FIG. 1, a rectangular door frame 100 having a center formed of a vertical frame 110 and a horizontal frame 120 is formed at an opening of a wall, and the door frame 100 is formed. One side of the vertical frame 110 inside the door 200 is hinged coupled to be configured to open and close, the user is able to block the user's entry and exit by opening and closing the door.

그러나 상기와 같은 종래의 실내도어는 건축물의 창문이 열려 있을 경우 개방된 도어가 외부로 부터 불어오는 바람의 압력을 이기지 못하고 갑작스럽게 닫히는 일이 발생하였으며, 사용자의 부주의로 도어에 무리한 외력을 가해 닫혀지는 일이 발생되는등 도어에 무리한 힘이 가해지는 경우가 많은 것인바.However, in the conventional indoor door as described above, when the window of the building is open, the open door suddenly closes without overcoming the pressure of the wind blowing from the outside, and the user closes the door by applying excessive force to the door. Excessive force is often applied to the door, such as losing.

이러한 경우 도어가 닫힐시 도어와 문틀간에 상당한 충격이 발생되는 것으로, 이러한 충격은 심할경우 도어의 파손을 가져올 수 있으며, 도어의 수명 단축을 가져오는 문제점이 있었다.In this case, when the door is closed, a significant impact is generated between the door and the door frame. If such a shock is severe, the door may be damaged and the life of the door may be shortened.

또한, 도어와 문틀의 충격시 발생되는 충격음에 의해 실내에 있는 사람들이 놀라는등의 여러가지 문제점이 발생하였다.In addition, various problems, such as amazement of people in the room by the impact sound generated during the impact of the door and the door frame occurred.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 도어가 외력에 의해 갑작스럽게 닫히더라도 도어가 일정구간에 오게되면 문틀에 설치된 충격흡수장치에 의해 도어가 문틀과 접하는 최종구간까지 자연스럽게 닫히게 하므로서, 도어와 문틀간에 발생되는 충격을 없애주어 도어의 파손 방지와 수명연장을 가져올 수 있으며, 이로인해 충격음 또한 방지할 수 있게 한 건축물 실내도어 충격흡수구조를 제공함에 본 발명의 목적이 있다.The present invention has been made to solve the above problems, even if the door is suddenly closed by external force, so that the door naturally closes to the final section in contact with the door frame by the shock absorbing device installed in the door frame when the door comes in a certain section. It is an object of the present invention to provide a shock absorbing structure of the building indoor door to eliminate the impact generated between the door and the door frame to prevent the damage of the door and to prolong the life, thereby preventing the impact sound.

이때, 상기한 각각의 구성요소는 그 재질은 금속재를 사용함이 바람직한 것이다.At this time, it is preferable that each of the above components uses a metal material.

이에, 상기와 같은 구성을 갖는 본 발명 건축물 실내도어 충격흡수구조의 작용에 대하여 살펴보면 다음과 같다.Thus, look at the action of the indoor door shock absorbing structure of the present invention building having the configuration as described above are as follows.

본 발명 건축물 실내도어 충격흡수구조는 도어(2)가 결합되는 문틀의 내측에 충격흡수 장치가 장착되는 것으로, 도어(2)가 닫혀질시 문틀에 전해지는 충격을 최소화 하기 위한 것이다.The indoor door shock absorbing structure of the present invention is to minimize the impact transmitted to the door frame when the door 2 is closed, as the shock absorbing device is mounted inside the door frame to which the door 2 is coupled.

도 4 및 도 5의 도시와 같이 도어(2)는 통상의 개방방법과 같이 경첩을 축으로 하여 개방이 이루어 지는 것이며, 이때 공압실린더(20)의 실린더몸체(21)내에 압축 내입된 스프링(24)은 그 탄성에 의해 피스톤(25)을 밀어내게 되는 것이고, 이때 밀어내는 힘은 피스톤(25)과 연결된 피스톤로드(26)를 통해 지지판(40)에 전해지는 것이다.As shown in Figs. 4 and 5, the door 2 is opened with a hinge as in the usual opening method, and at this time, a spring 24 compressed into the cylinder body 21 of the pneumatic cylinder 20 ) Is to push the piston 25 by its elasticity, the pushing force is transmitted to the support plate 40 through the piston rod 26 connected to the piston 25.

이때, 지지판(40)은 지지판케이스(30) 내에서 힌지(H)를 축으로 회전 전개되는 것이며, 피스톤(25)과 지지판(40)을 연결해주는 피스톤로드(26) 또한 피스톤(25)과 지지판(40)에 힌지결합되여 지지판(40)의 원만한 회전전개가 가능한 것이다. At this time, the support plate 40 is rotated and deployed about the hinge (H) in the support plate case 30, the piston rod 26 connecting the piston 25 and the support plate 40 also the piston 25 and the support plate Is hinged to (40) is a smooth rotational development of the support plate (40) is possible.

이때, 회전전개되는 지지판(40)은 상기 피스톤(25)이 지지판케이스(30)의 후면에 도달하면 그 전개가 종료되는 것이며, 일정한 각도를 가지며 전개상태를 유지 하는 것이다.At this time, when the piston 25 reaches the rear surface of the support plate case 30, the supporting plate 40 is rotated, and the development is completed, and maintains the developed state with a constant angle.

또한, 상기와 같이 스프링(24)의 탄성에 의해 밀려진 실린더몸체(21)의 내부에는 공간부가 형성되는 것으로, 그 공간부에는 배출관(50)과 연장관(22)을 통해 공기가 유입 충전되는 것이다.In addition, a space portion is formed inside the cylinder body 21 pushed by the elasticity of the spring 24 as described above, and the space portion is filled with air through the discharge pipe 50 and the extension pipe 22. .

상기와 같이 도어(2)가 개방된 상태에서 도어(2)에 어떠한 외력이 가해져 갑작스럽게 닫히게 되면 도어(2)는 급격히 닫히게 되는 것이며, 이때 도어(2)의 단부 가 지지판(40)과 면접됨과 동시에 지지판(40)에 전해진 외력은 지지판(40)의 절첩과 함께 피스톤(25)을 밀어내려는 외력이 부여되는 것으로, 이때 실린더몸체(21) 내에 충전된 공기는 비교적 작은직경을 갖는 연장관(22)과 배출관(50)을 통해 빠져 나갈수 있는 양이 제한되어 있으므로 순간적인 공기의 압축으로 그 외력을 흡수하게 되는 것이며, 실린더몸체(21)내에서 압축된 공기가 서서히 배출관(50)을 통해 외부로 배출되며 도어(2)와 문틀(1)의 충격없이 원만한 닫힘이 이루어 지는 것이다. As described above, if any external force is applied to the door 2 and the door 2 is suddenly closed while the door 2 is opened, the door 2 is suddenly closed, and the end of the door 2 is interviewed with the support plate 40. At the same time, the external force transmitted to the support plate 40 is given an external force to push the piston 25 together with the folding of the support plate 40, wherein the air filled in the cylinder body 21 has an extension pipe 22 having a relatively small diameter. And the amount that can be escaped through the discharge pipe 50 is limited is to absorb the external force by the compression of the instantaneous air, the air compressed in the cylinder body 21 is gradually discharged to the outside through the discharge pipe (50) And the smooth closing of the door (2) and the door frame (1) is made.

한편, 도 5의 도시와 같이 지지판(40)은 지지판삽입홈(31)에 안착됨과 동시에 지지판(40)에 부착된 탄성패드(41)에 의해 완전한 충격이 흡수되며 도어의 닫힘이 마무리 되는 것이다.Meanwhile, as shown in FIG. 5, the support plate 40 is seated in the support plate insertion groove 31 and at the same time, a complete shock is absorbed by the elastic pad 41 attached to the support plate 40, and the closing of the door is finished.

한편, 상기와 같은 충격흡수구조는 도 6의 도시와 같이 문틀(1)의 수직틀(10)에 다수개 설치함으로 그 충격흡수 부위를 분산시켜 사용함이 바람직한 것이다.On the other hand, the shock absorbing structure as described above is preferably used by dispersing the shock absorbing portion by installing a plurality in the vertical frame 10 of the door frame (1) as shown in FIG.

이상과 같이 본 발명은, 도어가 문틀과 접하는 최종구간까지 자연스럽게 닫히게 하므로서, 도어와 문틀간에 발생되는 충격을 없애주어 도어의 파손 방지와 수명연장을 가져올 수 있으며, 이로인해 충격음 또한 방지할 수 있는 효과를 얻을 수 있는 것이다.As described above, the present invention allows the door to naturally close to the final section in contact with the door frame, thereby eliminating the impact generated between the door and the door frame, thereby preventing the door from breaking and extending the life, thereby preventing the impact sound. Will be obtained.
