To provide a stair lifting device that enables stable ascending and descending of stairs with a simple configuration.SOLUTION: A stair lifting device has a loading platform, a pair of legs that support the loading platform, a pair of slide mechanisms that are provided between the pair of legs and the loading platform and can move the loading platform and the pair of legs relatively in a first direction parallel to the surface of the loading platform, and a plurality of wheels provided in the loading platform. The pair of legs has grounding feet provided adjacent to each other in a second direction intersecting the first direction and provided to face the loading platform, respectively, a lifting mechanism that changes the distance between the grounding foot and the loading platform, and a pantograph-type link mechanism that is provided between the grounding foot and the loading platform and has a pair of arms that are swingably connected. Each of the pair of grounding feet is provided so as to straddle the position of the center of gravity of a member above the grounding feet in the second direction.SELECTED DRAWING: Figure 2
【課題】簡易な構成で、安定した階段昇降を行うことができる階段昇降装置を提供する。【解決手段】階段昇降装置は、荷台と、荷台を支持する1対の脚部と、1対の脚部と荷台との間にそれぞれ設けられ、荷台の表面に平行な第1方向に荷台と1対の脚部とを相対的に移動できる1対のスライド機構と、荷台に設けられた複数の車輪と、を有し、1対の脚部は、第1方向と交差する第2方向に隣り合って設けられるとともに、それぞれ、荷台と対向して設けられた接地足部と、接地足部と荷台との間の距離を変更する昇降機構と、接地足部と荷台との間に設けられ、1対のアームが揺動可能に接続されたパンタグラフ式のリンク機構と、を有し、1対の接地足部は、それぞれ、接地足部よりも上側の部材の、第2方向での重心位置を跨がって設けられる。【選択図】図2
