To provide a stair lift mechanism that is simply configured and light-weight and that can move with a small force when moving over steps of stairs.SOLUTION: A step lift mechanism configured to move up and down steps of stairs is structured such that one end of each of rotation cranks 3 is rotatably fitted to a lower end of each of frames 2 extending and retracting in a vertical direction and that a center shaft 6 of each of wheels 5 is rotatably fitted to the other end of each of the rotation cranks 3. Thus, the frames 2 and the wheels 5 are rotatably connected via the rotation cranks 3.SELECTED DRAWING: Figure 1
【課題】構造がシンプル且つ軽量であり、階段の段差部を超えるときに少ない力で移動することができる階段昇降機構を提供する。【解決手段】階段の段差部を昇降可能に構成された階段昇降機構であって、上下方向に延伸するフレーム2の下端部に回転クランク3の一端部を回転自在に枢着させると共に、回転クランク3の他端部に車輪5の中心軸6を回転自在に枢着させて、回転クランク3を介してフレーム2と車輪5をそれぞれ回転自在に連結させる。【選択図】図1
