LIFTING DEVICE AND UNDERFLOOR STORAGE USING LIFTING DEVICE

To provide a low floor-type lifting device capable of obtaining a high load and a high lift and having a structure simple and not larger than an area of a storage as viewed from above.SOLUTION: A lifting device consists of: a base; a table part; a lifting part raising/lowering the table part; a pedestal; a driving part for moving the pedestal in a horizontal direction; and a regulation part for regulating the movement of the table part in the horizontal direction. The lifting part has a cam structure and consists of a first inclined part as a follower and a cum part as a driver. The lifting part raises/lowers the table part according to a relative position between an inclined surface of the first inclined part and the cam part. The first inclined part or the cam part is arranged at the bottom of the table part, and the corresponding cam part or the inclined part is arranged on the pedestal. The pedestal is moved in the horizontal direction and the relative position between the inclined surface of the first inclined part and the cam part is changed so as to raise/lower the table part.SELECTED DRAWING: Figure 1 【課題】シンプルな構造で、上面視、収納庫の面積よりも大きくない構造で低床型且つ高荷重・高揚程を得られる昇降装置を提供する。【解決手段】基台と、テーブル部と、テーブルを昇降させる昇降部と、台座と、台座を水平方向に移動させる駆動部と、テーブル部の水平方向への移動を規制する規制部とから成り、昇降部は、カム構造であり、従節である第１の傾斜部と、原節であるカム部とから成り、第１の傾斜部の傾斜面とカム部との相対位置に応じて、テーブル部を昇降させ、テーブルの底部に、第１の傾斜部又はカム部が配置され、台座部に、対応するカム部又は傾斜部が配置され、台座を水平方向に移動させ、第１の傾斜部の傾斜面とカム部との相対位置を変化させ、テーブル部を昇降させるという構成を採用した。【選択図】図１
