Description

도어용 경첩 조립체{Hinge assembly for door}Hinge assembly for door

본 발명은 도어용 경첩 조립체에 관한 것으로서, 보다 상세하게는 열린 도어가 설정된 정도 이상으로 닫혔을 때, 열린 도어가 자동으로 닫히도록 하는 도어용 경첩 조립체에 관한 것이다. The present invention relates to a hinge assembly for a door, and more particularly, to a hinge assembly for a door so that the open door is automatically closed when the open door is closed more than a set degree.

일반적으로 도어용 경첩은 수동으로 동작시키는 경첩과 스프링이나 유압을 이용하여 열린 도어가 자동으로 닫히도록 하는 자유경첩으로 나누어진다.In general, the door hinge is divided into a hinge for manually operating and a free hinge for automatically closing the open door using a spring or hydraulic pressure.

위와 같은 경첩들 중 상기 자유 경첩은 도어를 열고난 후, 유압이나 스프링의 탄성에 의해 일전한 힘을 유지하도록 하여 서서히 도어가 닫히도록 하게 한다.Of the hinges above, the free hinge after opening the door, by maintaining the full force by the hydraulic pressure or the elasticity of the spring to close the door gradually.

그런데 이러한 종래의 자유 경첩은 도어가 거의 닫히기 직전에 문틀과 마찰 등으로 인하여 저항이 커지게 되고, 상대적으로 탄성과 유압은 조금씩 떨어지게 되므로 도어가 완전히 닫히지 못하는 문제가 자주 발생하였다. 이러한 결점을 해소하기 위하여 유압과 탄성을 크게 하여 도어가 닫힐 때 보다 큰 힘으로 작동되도록 할 수 있으나, 큰 응력이 작용되어 경첩의 내구 수명을 단축시킬 뿐만 아니라, 빠른 닫힘으로 인하여 원하는 안전한 닫힘 속도를 얻기 어려운 문제점이 있었다.However, such a conventional free hinge has a large resistance due to friction with the door frame just before the door is almost closed, and the elasticity and hydraulic pressure are slightly dropped, so that the door cannot be completely closed. In order to solve this drawback, the hydraulic pressure and elasticity can be increased so that the door can be operated with higher force when the door is closed. There was a problem that was difficult to obtain.

위와 같은 문제점을 해결하기 위하여, 도어가 닫힐 때에는 사용자가 원하는 안전한 속도로 닫히도록 하되, 최종으로 닫히는 순간 비틀림 스프링의 복원력이 효과적으로 작용하게 되어 도어의 닫힘 동작이 완전하게 이루어지도록 하였다. In order to solve the above problems, the door is closed at a safe speed desired by the user, but the closing force of the torsion spring is effectively operated at the moment of closing the door to complete the closing operation of the door.

그러나 위와 같은 종래의 경첩에 있어서는, 그 장치의 구성이 복잡하여 생산성이 떨어지고, 이 때문에 생산원가가 상승할 뿐만 아니라 제작공정이 복잡하지고 수율이 떨어져서 양산이 어렵다는 단점을 갖는다.
