Claims (4)
- 자전거의 골격을 형성하는 프레임(30)에 회전가능하게 설치되고, 상기 프레임(30)에서 멀어질수록 직경이 커지고 톱니의 갯수가 많아지는 다수개의 체인링(54,56,58)이 동심으로 배치되며, 상기 체인링(54,56,58)에 체인(C)이 걸어감아져서 구동력을 전달하는 체인링세트(52)와;상기 체인링세트(52)의 회전중심에 일단이 연결되고 타단에 페달이 설치되어 운전자의 답력을 전달받아 프레임(30)에 설치되는 크랭크축(84) 및 상기 체인링세트(52)와 일체로 회전되는 크랭크암(82)과;상기 다수개의 체인링(54,56,58) 중 가장 내측에 위치한 내측체인링과 상기 프레임(30)사이에 형성되는 간격을 차폐하도록 상기 체인링세트(54,56,58)에 일체로 형성되어 상기 프레임(30) 방향으로 연장되는 다수개가 일정 간격을 두고 형성되며 상기 체인링세트(52)에 연결되는 부분이 상대적으로 폭이 넓고 선단부로 갈수록 폭이 좁은 프로텍터편(62)을 포함하여 구성됨을 특징으로 하는 자전거의 크랭크 조립체.
- 제 1 항에 있어서, 상기 프로텍터편(62)은 사다리꼴 형상임을 특징으로 하는 자전거의 크랭크조립체.
- 제 1 항 또는 제 2 항에 있어서, 상기 프로텍터편(62)은 상기 체인링세트(52)의 회전중심을 향해 경사지게 연장됨을 특징으로 하는 자전거의 크랭크조립체.
- 제 3 항에 있어서, 상기 프로텍터편(62)은 상기 프레임(30)측과 가장 인접한 상기 내측체인링(58)에 일체로 형성되는데, 상기 내측체인링(58)의 관통부의 가장자리를 따라 일정 간격으로 형성된 상기 내측체인링(58)의 체결편(60) 사이사이에 형성됨을 특징으로 하는 자전거의 크랭크조립체.
