<P>PROBLEM TO BE SOLVED: To secure safety when a loading section loaded with a bathing person is transferred to the outside from an ascending/descending bathtub. <P>SOLUTION: The ascending/descending bathtub 1 includes a lock detecting section for detecting that a carriage of a stretcher is locked to the ascending/descending bathtub. An upper table 16 of a lifter for lifting/lowering a movable bathtub with respect to a stationary bathtub comprises a descending end operation piece 26 and a descending intermediate operation piece 27. A lower table 15 comprises a lower end limit switch LS3 and a descending intermediate limit switch LS4. The descending intermediate operation piece 27 is installed below the descending end operation piece 26, so as to abut on the descending intermediate limit switch LS4 earlier and put it into an ON-state. In the case where the lock detecting section detects that the carriage is not locked to the ascending/descending bathtub 1, the movable bathtub is stopped in a descending intermediate position to disable the movement of a stretcher body. In the case where the carriage is locked to the ascending/descending bathtub 1, the movable bathtub is lowered until abutting on the lower end limit switch LS3 without being stopped even when the descending intermediate limit switch LS4 is put into the ON-state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
