PROBLEM TO BE SOLVED: To reduce danger, and improve the usability by constituting a bath lift device in such a manner that tap water is fed, and the water pressure is increased and fed to a vertically driving means. SOLUTION: When a seat at the lowest location is raised, a faucet J of tap water is opened, and the tap water is introduced into a booster 6 from an introduction port 604, and the pressure is increased. At the same time, a switching valve V1 is set to a rising location, and a discharging port 610 and a cylinder chamber 52 of a water pressure cylinder 5 are made to communicate with each other. Thus, a high pressure water of which the pressure is increased flows into the cylinder chamber 52, makes a rod 51 stick out, and raises the seat 3. The rising speed is regulated by the opening degree of the tap water faucet J. The water which has finished the work is accumulated in a weight member 7, and functions as a counterweight. After the rising, the switching valve V1 is set at a stop location. When the seat 3 is lowered, the switching valve V1 is set at a lowering location, and the water in the cylinder chamber 52 is drained. By this constitution, this bath lift device becomes safe, and the usability is improved. |
