Guided to move to the normal protective position on the side.

The bathing apparatus 1 according to the present embodiment has the above-described configuration. Next, a bathing method will be described as its function.
When bathing a person requiring assistance, the movable bathtub 14 of the bathing apparatus 1 shown in FIG. In this state, the movable bathtub 14 is in a state where the upper surface 14a is inclined, for example, by −28 degrees with respect to the horizontal plane. In this state, since the movable bathtub 14 is in a state in which the sealing members 32 and 32 are open and the notch 31 is opened, the assistant is guided to the movable bathtub 14 with the wheelchair 3 on which a bather (not shown) is seated facing backward. To do.

When the wheelchair 3 is moved into the movable bathtub 14, the pedestal 5 enters the lower side of the fixed base 13, the seating portion 8 and the backrest portion 9 enter the movable bathtub 14, and the support rod 7 reaches the bottom of the notch 31. Enter towards the club. As shown in FIG. 3, the seating portion 8 and the backrest portion 9 of the wheelchair 3 enter the movable bathtub 14, and the first abutment shaft 23 provided on the backrest portion 9 is one inner wall 21 a of the movable bathtub 14. It stops at the position where it abuts on the first abutment surface 24.
At this position, the support rod 7 is in a position where it does not reach the concave portion 33 at the outermost portion of the notch 31, and a gap K is formed between the back portion of the seating portion 8 of the wheelchair 3 and one inner wall 21a. . This position of the wheelchair 3 is set as a temporary holding position.

In addition, when the base 5 of the wheelchair 3 enters under the fixed base 13 and enters, the limit switch 38 in which the tip of the base 5 hangs down below the base 20 at the temporary holding position is pushed. Then, the drive cylinder 28 is driven and extended by a rod 29 that is extended through control means (not shown), and the base 20 and the movable bathtub 14 are rotated by a small angle, for example, 8 degrees clockwise around the rotation shaft 18. To do.
As the base 20 and the movable bathtub 14 installed on the base 20 rotate clockwise around the rotation shaft 18, the inclined surface 40a of the guide portion 40 provided on the base 20 is seated as shown in FIG. The wheelchair 3 is pushed by being brought into contact with the roller 12 of the portion 8 and moved to the inner side of the movable bathtub 14 and pushed in.
As a result, the wheelchair 3 advances toward the inner flange portion side of the notch 31, and the support rod 7 reaches and is held in the fitting recesses 33, 33 which are the uppermost portion of the notch 31. When the support rod 7 reaches the fitting recesses 33, 33, the switch 36 provided at the outermost part of the notch 31 is pushed, so that the open / close cylinder 35 is closed via a control means (not shown) and the seal members 32, 32 are notched. 31 is closed in a liquid-tight manner, and the support rod 7 is held in a liquid-tight manner by the fitting recesses 33 and 33. This position of the wheelchair 3 is set as a regular holding position.

The first abutment shaft 23 is separated from the first abutment surface 24 with the rotation of the movable bathtub 14 at the normal holding position where the wheelchair 3 is pushed into the heel side of the movable bathtub 14. At this position, the base 20 is held horizontally, and the upper surface 14a of the movable bathtub 14 is at a reference position tilted, for example, by about 20 degrees with respect to the horizontal plane.
In this state, as shown in FIG. 8, the seating portion 8 of the wheelchair 3 is held at a reference position in contact with the other inner wall 21 b in the movable bathtub 14. Moreover, the wheelchair 3 is fixed and held in a liquid-tight manner in the movable bathtub 14 by fitting and holding the sealing members 32 and 32 and the support rod 7 which are in contact with each other by the recesses 33 and 33. In this state, the wheelchair 3 is positioned and held at a proper holding position in the movable bathtub 14.

Next, by pressing an operation switch in a panel switch (not shown) provided on the upper surface 14 a of the movable bathtub 14, the drive cylinder 28 further extends the rod 29, and the base 20 and the movable bathtub 14 are centered on the rotation shaft 18. Then, the upper surface 14a of the movable bathtub 14 becomes substantially horizontal as shown in FIG.
As a result, the wheelchair 3 held between the seal members 32 and 32 is also lifted together with the movable bathtub 14 and rotated. At this time, since the rotation shaft 18 that forms the center of rotation is located on the back side (right side in the figure) of the base 20 and the movable bathtub 14, the wheelchair 3 held by the movable bathtub 14 rotates in the clockwise direction. Therefore, the pedestal 5 and the casters 6 positioned below the fixed base 13 do not collide with the floor surface, and are smoothly rotated and lifted.

The bather seated on the seating portion 8 of the wheelchair 3 enters a bathing state by supplying hot water from the tank 17 into the movable bathtub 14 at the bathing position where the upper surface 14a of the movable bathtub 14 is held substantially horizontally. At this time, the notch 31 and the support rod 7 provided on the other inner wall 21b of the movable bathtub 14 are liquid-tightly sealed by the seal members 32, 32 and the fitting recesses 33, 33, so that no hot water leaks.

As described above, according to the bathing apparatus 1 according to the present embodiment, when the wheelchair 3 is advanced into the movable bathtub 14 at the entrance / exit position, the other inner wall 21b of the base 20 and the movable bathtub 14 is inclined downward (horizontal plane). Therefore, the seat portion 8 and the backrest portion 9 can be easily transferred to the temporary holding position.
And when making the seating part 8 of the wheelchair 3 approach into the movable bathtub 14, the caregiver should just move the support rod 7 of the wheelchair 3 to the temporary holding position along the notch 31, and to the subsequent normal holding position. For the transfer, the seat switch 8 and the support rod 7 are automatically moved by detecting the wheelchair 3 in the temporary holding position with the limit switch 38 and driving the drive cylinder 28 to change the posture of the movable bathtub 14 to the reference position. Since it can be pushed into the inner tub of the bathtub 14 and transferred to the regular holding position, the burden on the waist of the assistant who has conventionally pushed the wheelchair 3 to the regular holding position can be reduced.
Thereafter, by pressing the operation switch of the panel switch on the upper surface 14a of the movable bathtub 14, the drive cylinder 28 is further driven to rotate the movable bathtub 14 and the base 20 until the upper surface 14a becomes substantially horizontal, and bathing is performed. Can be held in position.

In addition, since the movable bathtub 14 is formed in a substantially V shape in which the two inner walls 21a and 21b form an obtuse angle in a longitudinal sectional view, the movable bathtub 14 can be bathed with a relatively small amount of hot water.
Moreover, the bathing apparatus 1 according to the present embodiment, when the base 20 and the movable bathtub 14 are rotated between the entrance / exit position and the bathing position, the back side of the movable bathtub 14, that is, the back side opposite to the entry direction of the wheelchair 3. Since the rotary shaft 18 is provided, when the movable bathtub 14 is rotated from the reference position to the bathing position, the caster 6 of the wheelchair 3 that is held by the movable bathtub 14 and rotates integrally does not interfere with the floor surface. It can be rotated.
