Claims (4)

  1. 전기 회로 차단기의 조작 핸들이 이동을 소정의 한계위치에 제한하는 장치로서, 핸들 아암 수단과, 상기 핸들 아암수단을 손으로 제어할 수 있도록 하는 조작 핸들을 포함하되, 상기 조작 핸들은 온 위치와 오프 위치와 전기 접점을 점유할 수도 있으며, 그중 적어도 하나는 개방위치나 폐쇄위치로 이동 가능한 것인 장치에 있어서; 돌출 지점을 점유하기 위해 회로 차단기의 전기 접점이 폐쇄되는 경우와 수축위치를 점유하기 위해 회로 차단기의 전기 접점이 개방되는 경우, 가동 전기 접점이 기계적으로 연결되어 그와 함께 이동가능한 크로스바 수단과; 조작핸들이 온 위치에서 오프 위치로 이동하는 경우, 상기 폐쇄된 접점을 개방시키기 위해, 중간 지점이 서로 이어지며 상기 중간 지점에서 상기 핸들 아암까지 스프링에 의해 기계적으로 연결된 상, 하부 토글 링크를 포함하는 연계수단과; 상기 조작 핸들이 온 위치에서 오프 위치로 이동된 후에도 상기 전기 회로 차단기의 전기 접점이 폐쇄위치에 남아 있게 되는 경우, 상기 조작 핸들의 이동을 온 위치와 오프 위치사이의 소정의 한계점에서 정지시키기 위해 레버로 부터 돌출된 레버 정지 수단을 구비하는 상기 하부 토글 링크를 포함하는 장치.
  2. 제1항에 있어서, 상기 핸들 제한 수단은 상기 하부 토글 링크와 일체로 형성된 돌출 부재를 포함하며, 회로 차단기의 전기 접점이 폐쇄 위치에 남아 있고, 상기 크로스바 수단이 상기 하부 토글 링크 돌출 부재의 경로로부터 떨어져 이동되지 않는 경우, 상기 하부 토글 링크 돌출 부재가 상기 크로스바 수단과 접촉되게 되는 장치.
  3. 제2항에 있어서, 상기 핸들 제한 수단은 상기 상부 토글 링크와 일체로 형성된 제2돌출부재를 더 포함하며, 상기 핸들 아암수단은 상기 상부 토글 링크 돌출 부재의 경로내에 배치된 부재를 가짐으로써, 상기 하부 토글 링크 돌출 부재가 상기 크로스바 수단에 의해 차단되는 경우, 작동 핸들이 상기 상부 토글 링크 돌출 부재와 결합된 상기 핸들 아암 수단 부재에 의해 상기 제한 위치를 넘어 이동되지 못하도록 제한되는 장치.
  4. 제3항에 있어서, 회로 차단기가 작동된 경우 상기 크로스바 수단으로 부터 떨어져 초기 위치로 이동되는 상기 연계수단과, 상기 핸들 아암수단 부재에 위해 맞물려지는 상기 상부 토글 링크 돌출 부재를 구비하여, 상기 초기 위치에 놓여진 상기 연계수단 위의 작동 핸들의 이동을 차단하는 장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.
