Claims (5)

  1. 일측 표면체가 타측의 경사가능형 또는 고정형 표면체에 대해 이동되는 의자의 등널, 캐비넷등의 드롭 도어와 같이, 축선을 중심으로 기울어질 수 있는 하나이상의 표면체의 불의의 동작을 방지시키기 위해, 양측 표면체사이에 설치되고 또한 적어도 하나의 고정부품과 그리고 이 고정부품에 대해 길이가 다양하게 변화되어 상기의 불의의 동작을 해제시키는 부품으로 갖추어진 의자등널등의 불의의 동작방지장치에 있어서, 일측 고정부품은 T-형 헤드(5)로서 스크루우(4)에 접속되고 타측 고정부품은 상기 T-형 헤드와는 다른 별개의 스터브 튜브형상의 헤드로서 관형케이싱(2)과 함께 형성되며, 상기 관형 케이싱은 그의 내부벽에 원추형 제동표면을 갖춘 플러그(11)는 물론 상기 스크루우(4)상에 이동되는 스러스트 및 로울링 요소들을 위해 축방향으로 연속된 안내 및 제동표면을 형성하고 있으며, 상기 플러그(11)는 스크루우(4)상에 회전가능하게 안내되어져서, 적어도 어느 하나의 표면체(17 또는 18)가 급작 또는 난폭한 동작을 하는 경우에는 케이싱(2)의 제동표면(9)상에 강제고정방식으로 구속되어질 수 있게 구성된 것을 특징으로 하는 의자등널등의 불의의 동작 방지장치.
  2. 제1항에 있어서, 상기 일측의 헤드(5)에 구멍이 형성되고 그 구멍을 통해 핀(25)이 삽입되어 상기 헤드를 표면체(17 또는 18)에 연결시키며, 관형케이싱(2)에 부가된 타측 헤드(5)는 스터드(26)를 위한 스터브튜브형상의 횡편(6)을 형성하고 있으며, 상기 타측 헤드는 상기 스터드를 통해 타측 표면체(17 또는 18)에 연결되는 것을 특징으로 하는 장치.
  3. 제1항에 있어서, 상기 스쿠루우는 케이싱(2)에 축방향으로 배치되고, 상기 플러그(11)는 케이싱(2)의 종축선을 따라, 상기 플러그의 각측부에 제공된 스러스트 베어링 및 상기 스러스트 베어링의 축방향 억제부를 형성하는 엔드 디스크(10)를 갖추고 있으며, 상기 스러스트 베어링과 엔드 디스크 사이에는 스프링이 내재되는 것을 특징으로 하는 장치.
  4. 제1항에 있어서, 플러그(11)는 제동표면(24)이 형성된 원형너트의 형태로 구성되고, 케이싱(2)의 내부벽에는 상기 제동표면(24)을 위한 원추형제동표면(9)이 마련되는 것을 특징으로 하는 장치.
  5. 제1항에 있어서, 회전의자의 시트장착부에 적용됨에 있어, 시트장착부가 3개의 작용부 즉, 의자의 축받이와 연결된 기본구조물인 제1 작용부, 상기 기본구조물에 관절이음식으로 연결된 시트평판장착부인 제2장착용부 및 상기 시트평판 장착부에 관절이음식으로 고정된 등널지지 부인 제3작용부로 되어있는 상기 3개의 작용부에 의해 형성되고, 이들 3개의 작용부는 등널지지부로서 구성된 제3작용부가 기본구조물로서 구성되고 축받이에 고정된 제1작용부에 연결되는 것으로 이들 작용부의 경사를 허용하는 관절축선에 의해 상호 연결되고, 시트평판장착부로서 구성된 제2 작용부는 안내 이동가능하며 그리고 상기 작용부의 동작을 구속하기 위해 상기 시트장착부상에는 안전장치로서 구성된 불의의 동작방지 장치가 제공되어 있는 것으로서, 상기 불의의 동작 방지 장치(1)가 일단은 등널지지부(20)에 그리고 타단은 각각의 헤드(5)를 통해 기본구조물(22)에 관절이음식을 연결되어 있는 것을 특징으로 하는 장치.
