Description

축소된 조향베어링을 갖춘 절첩식 휴대용 자전거
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 신규한 특징을 구현시킨 절첩식 휴대용 자전거를 절첩하지 않은 상태로 나타낸 투시도.
제9도는 조향베어링의 수직단면 확대도.
제10도는 바퀴정렬요소를 분리시켜 분해하여 축소도시한 투시도로서, 한 요소는 그측 면일부를 잘라내 버리고 도시한 것.

Claims (8)

  1. 정면단부를 갖춘 절첩식 프레임, 전술한 정면단부에서 상방으로 연장되어 그 정면단부 아래로 절첩될 수 있도록 지지된 손잡이봉 조립체, 전술한 정면단부에서 하방으로 연장되어 자전거의 앞바퀴를 지지하는 앞바퀴지주, 손잡이봉 조립체를 앞바퀴 지주에 연결하는 연결장치 및 전술한 프레임상에서 손잡이봉 조립체와 앞바퀴 지주를 회전식으로 지지하는 조향베어링으로 구성한 절첩식 휴대용 자전거로서, 전술한 베어링을 전술한 정면단부에 고정되어 앞바퀴지지대와 베어링집을 형성하는 호상의 좁은 집과, 이집과 전술한 연결장치사이에 들어가는 베어링요소로 구성하여, 축방향의 길이는 비교적 짧게 하고 직경은 축방향의 길이 보다 훨씬 크게함으로서 사용중에 받는 하중은 충분히 견뎌내면서도 프레임의 절첩된 높이는 감소시키는 것을 특징으로 하는 절첩식 휴대용 자전거.
  2. 제1항에 있어서, 전술한 베어링요소의 축방향길이가 대략 그 직경의 1/4정도되는 것.
  3. 제1항에 있어서, 전술한 베어링요소를, 전술한 집과 연결장치사이에 배치되고 전술한 손잡이봉 조립체와 앞바퀴지주상에 달린 지지환과 전술한 집에 의해 형성된 궤도사이에서 축방향과 수직방향으로 제한되어 구르는 최소한 한줄의 베어링요소들로 구성한 것.
  4. 제3항에 있어서, 전술한 베어링 요소를, 서로 수직으로 거리를 두고서 마주한 면상에 단면형상이 V자인 환상홈을 제1홈으로 갖추고 있는 두개의 지지환과, 전술한 두 제1홈 사이에 배치되어 양쪽면상에 단면형상이 V자인 환상의 제2홈을 갖추고서 전술한 제1홈과 협동하여 두개의 베어링 궤도를 형성하는 전술한 집의 내측환 상테두리와, 전술한 궤도속에 제한되어 구르는 두줄의 볼로 구성한 것.
  5. 제3항에 있어서, 전술한 베어링 요소를, 서로 마주한 두면의 바깥모서리를 경사지게 깎아서 그 깎여진 두 경사면이 협동하여 바깥쪽으로 열린 단면형상이 자인 제1홈을 형성하여 전술한 제2홈과 함께 하나의 베어링 궤도를 형성토록 되어 있는 두개의 지지환과, 전술한 궤도속에 제한되어 구르는 한줄의 볼로 구성한 것.
  6. 제1항에 있어서, 전술한 연결장치를, 전술한 집을 통해서 연장되어 한쪽끝은 앞바퀴지주에 연결되고 다른 쪽끝은 전술한 손잡이봉 조립체에 연결되어 그들을 함께 끌어당겨서 전술한 조향 베어링의 양쪽에 지지시키는 나사식 연결구로 구성한 것.
  7. 제1항에 있어서, 전술한 절첩식 프레임을, 이 프레임을 절첩했을 때 서로 옆으로 나란히 배치되는 앞뒤바퀴를 지지하는 앞뒤바퀴지지체를 각각 갖추고 있음과 아울러 전술한 바퀴의 일부를 덮는 앞뒤펜더를 갖추고 있어서 절첩된 프레임을 세워놓았을 때 전술한 바퀴가 닿아 있는 수평선상에 전술한 펜더의 단부가 접촉함으로써 절첩된 프레임의 네군데 지지점들중 하나를 이루도록 되어있는 앞뒤 프레임 부분으로 구성한 것.
  8. 제7항에 있어서, 전술한 앞바퀴지지체는 자전거 절첩시에 도치시킴으로써 전술한 프레임을 절첩했을 때에 전술한 앞펜더의 뒷쪽끝이 뒷펜더의 뒷쪽끝과 나란히 배치되어 이 두 뒷쪽끝이 전술한 바 접촉단부를 형성하는 것.
