PROBLEM TO BE SOLVED: To improve operation property of a stair lifting device.SOLUTION: A stair lifting device 100, 200 comprises: a main body part 10 to which a wheel part 20 and a crawler part 40 are attached; a loading space part 60 which is provided to displace freely, to the main body part 10, and on which a baggage is mounted; and displacement mechanisms 70, 170 for displacing a position of the loading space part 60 to the main body part 10, to different positions when moving on a flat ground and when going up the stair. The crawler part 40 has an area where contacts the stair when a user goes up the stair, and the displacement mechanisms 70, 170 displaces the loading space part 60 to the main body part 10, so that, a barycenter G of the baggage L is positioned on a position vertically above the area, when a user goes up the stair.SELECTED DRAWING: Figure 8
【課題】階段昇降装置の操作性を向上させる。【解決手段】階段昇降装置100,200は、車輪部20及びクローラ部40が取り付けられる本体部10と、本体部10に対して変位自在に設けられ、荷物が載置される荷台部60と、本体部10に対する荷台部60の位置を、平地を移動する際と階段を昇降する際とで異なる位置に変位させる変位機構70,170と、を備える。クローラ部40は、階段を昇降する際に階段と接触する領域を有し、変位機構70,170は、階段を昇降する際、荷物Lの重心Gが領域の鉛直上方に位置するように本体部10に対して荷台部60を変位させる。【選択図】図8
