[Prior art]

 As the number of elderly households increases with the progress of nuclear families, various problems are starting to occur. Among them, the work of bathing an elderly person who needs nursing care was a heavy labor. In other words, the work of putting an elderly person with a lower body into the bathtub or raising it from the bathtub requires power, and two male caretakers are required to bathe an old man. As a result, the caregiver had to bear a considerable burden. In addition, the same applies to the bathing of persons with physical disabilities in the lower half of the body, which imposes a considerable burden on caregivers, and that weak women and the elderly cannot carry out smooth bathing work. Was there.

In light of such an actual situation, the present inventors have previously disclosed a “flow chair” in Japanese Utility Model Laid-Open No. 5-91671. This disclosed technique was created as a smooth bathing action for an elderly person with a lower body or a physically handicapped person, and as shown in FIG. 14, a substantially conical pedestal (a) and , A flow chair (Z) including a cylindrical shaft (c) having a seat receiving portion (b) formed above, and a circular seat portion (d) provided on the upper surface of the seat receiving portion (b). )Met. In this flow chair (Z), as shown in FIG. 15, a protrusion (e) is provided on the inner peripheral portion of the boundary between the cylindrical shaft (c) and the seat receiving portion (b). A claw (f 1) is provided on the lower surface. Further, a retaining member (h) for locking the seat portion (d) is provided in the inner space of the boundary portion between the shaft (c) of the seat receiving portion (b) and the seat receiving portion (b). A claw (g) that meshes with a claw (f) provided on the lower surface of the protrusion (e) is provided on the outer peripheral portion of the upper surface of the retaining member (h), and a bath is provided at the center of the seat portion (d). When a person applies a seating pressure, the elastic repulsive force causes a boundary between the cylindrical shaft (c) and the seat receiving portion (b), and a claw (f) on the lower surface of the protrusion (e) provided on the inner circumferential surface The engagement with the pawl (g) is disengaged, and the seat portion (d) is configured to be rotatable.

Therefore, when the elderly person or the physically handicapped person takes a bath, if the height of the flow chair (Z) is set to be the same as the height of the bathtub, the elderly person or the physically handicapped person can be lifted from the bathtub. At this time, the person can easily sit on the seat portion (d) of the flow chair (Z), and in this state, the bather presses the central portion of the flow chair (Z) seat portion (d). The seat portion (d) can be freely rotated by adding, so that one person can freely change the direction of the body. Moreover, when the bather lowers his legs while sitting on the seat (d) of the floor chair (Z) or changes the weight load position and applies pressure to the side of the seat (d), (F) and the pawl (g) are re-engaged with each other, the seat receiving portion (b) and the shaft (c) are fixed, and the body and face can be washed while sitting on the floor chair (Z).
