PROBLEM TO BE SOLVED: To provide an embarking-disembarking device capable of holding a slope in a horizontal state or an inclined state near to it even if a height difference between an embarking-disembarking deck and a pier is large, and capable of reducing an installation space of stairs in the pier more than a conventional embarking-disembarking device of changing in an inclination of the stairs.SOLUTION: The embarking-disembarking device comprises a stand arranged in the pier, a slope installing base mounted on an upper part of the stand, a slope for supporting a root part in a cantilever state by the slope installing base, base lifting means provided in the stand and horizontally lifting the slope installing base and expansion stairs for embarking-disembarking an embarking person to the slope installing base and always expanding-contracting at the same inclination on the basis of an upper surface of the slope installing base in response to a height from the ground surface of the slope installing base after lifting by the base lifting means. Thus, even if the height difference between the embarking-disembarking deck and the pier is large, the slope can be held in the horizontal state or the inclined state near to it, and the installation space of the stairs in the pier can be reduced more than the conventional embarking-disembarking device of changing in the inclination of the stairs.COPYRIGHT: (C)2014,JPO&INPIT【課題】乗降甲板と岸壁との高低差が大きくても、スロープを水平状態またはそれに近い傾斜状態で保持でき、かつ階段の傾斜角度が変化する従来の乗下船装置に比べて、岸壁における階段の設置スペースを小さくできる乗下船装置を提供する。【解決手段】岸壁に配置される架台と、架台の上部に搭載されるスロープ設置台と、スロープ設置台に片持ち状態で元部が支持されるスロープと、架台に設けられ、スロープ設置台を水平に昇降させる台昇降手段と、スロープ設置台に対して乗船者を乗降させ、かつ台昇降手段による昇降後のスロープ設置台の地面からの高さに合わせて、常にスロープ設置台の上面を基準に、同一の傾斜角度で伸び縮みする伸縮階段とを備えた。これにより、仮に乗降甲板と岸壁との高低差が大きくても、スロープを水平状態またはそれに近い傾斜状態で保持でき、階段の傾斜角度が変化する従来の乗下船装置より岸壁での階段の設置スペースを小さくできる。【選択図】図1
