The rear rail 10C is mounted on the upper end of the edge 4 of the bathtub 3 to facilitate the transfer of the seat body 41 between the inside and the outside of the bathtub 3. When the front end slides on the inner wall or the like of No. 3, it is automatically folded upward.

The handrail 70 has its base end fixed to the base of the lift 8 and its top end rises upward.
It extends horizontally across the front space above the lifting rail 10. The horizontal portion 71 is provided at a height near the chest of the bather M on the seat body 41. The handrail 70 in this case may be made of a metal pipe having a certain degree of rigidity so that the bather M may put his / her hand on it, but since the main purpose is to reduce the fear of the bather M. Alternatively, it may be made of a material having a relatively low strength, such as a resin.

Next, the operation will be described. When taking a bath, the caregiver runs the wheelchair 1 and approaches the edge 4 of the bathtub 3.
When approaching, the chair portion 44 is laid upward and the footrest 45 is lifted. In this state, the elevating rail 10 is raised, and the elevating rail 10 is made to coincide with the height of the rail 34 of the traveling vehicle 31. Then, the rail 3 of the traveling carriage 31
4 and the lifting rail 10 are arranged in a straight line. In this state, the lock release lever 49 is operated to separate the seat 41 from the traveling carriage 31, and the assistant pushes and moves the seat 41 to move on the elevating rail 10.

At this time, since the slide member 15 for fixing the seat body 41 is moved to a position near the edge 4 of the bathtub 3 by the action of the guide rail 20A, the caregiver does not reach much. The seat 41 can be placed on the slide member 15. Therefore, it is not necessary to take an unreasonable posture, and the burden of assistance is small. Also, the seat 41
Since the upper bather M is pushed out into the front space at a height above the water surface, the bather M may be terrified.
Fear can be eliminated.

When the seat 41 moves on the lift rail 10, the lock pin 48 urged in the locking direction automatically fits into the lock hole 16 of the slide member 15, and the seat 4
1 is locked to the slide member 15. Next, when the elevating rail 10 is lowered, the slide member 15 moves forward as it descends by the action of the guide rail 20A,
Along with this, the seat body 41 protrudes toward the center of the bathtub 3. When the guide roller 21 is further lowered, the guide roller 21 comes out of the groove of the guide rail 20A and lowers at the same position. Then, the seat body 41 sinks into an optimum position in the bathtub 3, and the backrest of the seating chair portion 44 enters the bathtub 3 without interfering with the bathtub wall surface.

After bathing, the lift rail 10 is raised.
Then, as the lift rail 10 rises, the seat 41 is brought closer to the edge 4 of the bathtub 3 by the action of the guide rail 20A. Therefore, the caregiver should not take an unreasonable posture,
The seat 41 can be transferred from the elevating rail 10 to the traveling carriage 31.

[0022]

As described above, the bathing apparatus of the present invention moves the seat on the elevating rail toward the center of the bathtub as the elevating rail descends, and moves the seat on the elevating rail as the elevating rail rises. A guide mechanism is provided to move the seat body to the edge of the bathtub, so when the seat body is transferred from the traveling carriage to the elevating rail, and conversely, the seat body is mounted on the traveling carriage from the elevating rail. When moving, the distance that the assistant pushes the seat can be reduced. Therefore, the caregiver can easily move the bather without greatly extending his hand in an unreasonable posture, and can reduce the burden on the caregiver.
