PROBLEM TO BE SOLVED: To provide a step eliminating lifting device which has the following characteristics: being certainly capable of being used even during power failure; not giving an oppressive feeling or discomfort to a user by eliminating the need for a gate-shaped stand or the like; eliminating the need for pit construction to reduce installation costs; being low in manufacturing costs; and having high space efficiency.SOLUTION: A step eliminating lifting device includes: a base 2 which is installed on a floor surface F; a lifting member 3 on which a flat part for putting a body A to be lifted thereon is formed, and which is lifted up and down by being guided by a guide member G of the base 2; and a lifting mechanism C and a driving device D which are positioned on the right and left sides of the flat part. The lifting mechanism C includes: a cam roller; and an inclined cam surface with which the cam roller is engaged, and which is inclined upward or downward to the front. The driving device D includes: a water pressure cylinder 5 driven by tap water pressure; and a water flow switching device 6 for switching a water flow direction. By extending and contracting the piston rod of the water pressure cylinder 5 to relatively move the cam roller and the inclined cam surface in the front and rear directions, the lifting member 3 is lifted up and down.
【課題】停電の際にも確実に利用でき、門型のスタンド等を不要にして違和感や圧迫感を与えることをなくし、ピット工事を不要にして設置コストを低減できるとともに、製造コストが低くスペース効率が高い段差解消昇降装置を提供する。【解決手段】床面Fに設置される基体2、被昇降体Aが載る平坦部が形成されるとともに、基体2のガイド部材Gに案内されて昇降する昇降部材3、前記平坦部の左右に位置する昇降機構C及び駆動装置Dを備え、昇降機構Cが、カムローラー及び前記カムローラーが係合する、前上がり傾斜又は前下がり傾斜する傾斜カム面により構成され、駆動装置Dが、水道水圧により駆動する水圧シリンダー5及び水流方向を切り替える水流切替装置6により構成され、水圧シリンダー5のピストンロッドを伸縮させて前記カムローラー及び前記傾斜カム面を相対的に前後方向へ移動させて昇降部材3を昇降させる。【選択図】図6
