Rollers 38 are provided on the lower surface of the seat portion 31 and the rear surface of the backrest 30.

When the loading portion 2 is descending, the roller 38 rolls when the roller 38 hits the side wall or the bottom wall of the bathtub 3, and the loading portion 2 rotates around the back rotation portion 29 to be in a backward inclined posture. Become.
The center of gravity of the total weight of the bather and the bath lift 44 is the vertical leg 10, the horizontal leg 11, and the opposite side (imaginary side) connecting the extended tip of the vertical leg 10 and the extended tip of the horizontal leg 11 in plan view. It is in a triangle.

  The fixed column 22 is erected at the connection intersection between the vertical leg 10 and the horizontal leg 11, but in another example, the center of gravity of the total weight of the bather and the bath lift 44 is secured in the triangle, The fixed column 22 is erected on the vertical leg 10 or the horizontal leg 11.

  The bathtub 3 for hot water storage and bathing is provided in a bathroom and has a rectangular shape in plan view. The bathtub 3 is appropriately filled with hot water with a hot water supply device.

When using Example 1, the loading part 2 is first stopped at the boarding / exiting position on the dressing room side.
The swinging rotation of the fork 18 of the wheel 15 is fixed, and the rotation of the rotating wheel 17 is fixed.
A bather is placed on the seat portion 31 of the placing portion 2. A belt 39 is hung on the upper body of the bather, and the bather is fixed to the riding part 2.

The raising switch 24 of the operation unit 26 is pushed to raise the lifting column 21.
That is, when the raising switch 24 is pressed, the actuator 8 is driven, and the actuator 8 raises the lifting column 21.

  During the ascent, the elevating column 21 does not rotate with respect to the fixed column 22 and rises in a translational manner. The elevating column 21 is raised to the upper limit. As the elevating column 21 rises, the arm 7 and the placing portion 2 rise.

Next, the assistant kicks up the rotation fixing pedal 20, releases the fixing action of the rotation wheel 17, and allows the rotation wheel 17 to freely rotate.
Further, the direction fixing pedal 19 is kicked up, the fixing action of the fork 18 of the wheel 15 is released, the head can be swung freely, and the direction of the wheel 15 (= moving direction) is made free.

The mobile bath lift 1 is moved from the dressing room to the bathtub 3.
In the vicinity of the bathtub 3, the lift switch 24 is pressed to raise the bather to the upper limit. The lower leg seat portion 32 is rotated to further raise only the bather's foot.

Next, the leg recess 40 in the vicinity of the connection intersection of the vertical leg 10 and the horizontal leg 11 is brought into contact with the left front corner 41 of the bathtub 3. The bather crosses the front edge 42 of the bathtub 3.
After the contact, the direction fixing pedal 19 is depressed to fix the swinging rotation, and the rotation of the rotating wheel 17 is fixed.
It is confirmed that the placing part 2 is coming directly above the bathtub 3.

  After confirmation, the actuator 8 is actuated to retract the advance / retreat shaft 27 of the actuator 8, the elevating column 21 is lowered, the platform 2 is lowered into the bathtub 3, the bather is immersed in the hot water in the bathtub 3, and bathing is performed Do.

  After the leg recess 40 is used for bathing in accordance with the left front corner 41 of the bathtub 3, when the leg recess 40 is aligned with the back left corner 42 of the bathtub 3 at the next use, the placing portion 2 is opened to the bathtub 3. Since the locking device 34 of the rotation mechanism 28 is loosened, the position of the mounting portion 2 is corrected by 90 degrees, and the mounting portion 2 is positioned immediately above the opening of the bathtub 3, and then the locking device The operation of fastening 34 and fixing the rotation mechanism 28 is performed.

  At the time of taking a bath, the assistant pushes the raising switch 24 and raises the placing portion 2 and the bather.

When the lifting column 21 reaches the upper limit, the direction fixing pedal 19 is depressed to release the fixation of the fork 18, and the rotation fixing pedal 20 is stepped to release the rotation wheel 17.
The mobile bath lift 1 is run from the bathtub 3 side to the dressing room.
The direction fixing pedal 19 is stepped on, the rotation fixing pedal 20 is further stepped on, and then the lowering switch 25 is pressed to lower the bather.
The belt 39 is removed, the lower leg seat portion 32 is lowered and returned to the original position, the bather is lowered from the seat portion 31, and bathing is completed.

When the mobile bath lift 1 is not used, the front part of the seat part 31 is lifted, the connection part 43 of the seat part 31 and the backrest 30 is bent, the seat part 31 is folded according to the backrest 30, and the belt 39 is used. The seat 31 is fastened to the backrest 30.
The leg 4 is closed, the occupied space of the mobile bath lift 1 is reduced, and the vehicle is run and stored in an appropriate storage location.

In the second embodiment shown in FIGS. 4, 5, and 6, the actuator 8 of the first embodiment is provided on the top of the column portion 6, and the horizontal leg folding shaft 46 is provided in the extending middle portion of the horizontal leg 11.
The lateral leg 11 according to the second embodiment includes a lateral leg base portion 11a, a lateral leg tip portion 11b, and a lateral leg folding shaft 46 that connects the lateral leg base portion 11a and the lateral leg tip portion 11b so as to be bent.
At the time of storage without using the second embodiment, the lateral leg tip portion 11 b is bent so as to be parallel to the vertical leg 10.

In the third embodiment, a vertical leg folding shaft 47 is provided in the middle of the extension of the vertical leg 10 of the second embodiment.
The vertical leg 10 according to the third embodiment includes a vertical leg base portion 10a, a vertical leg tip portion 10b, and a vertical leg folding shaft 47 that connects the vertical leg base portion 10a and the vertical leg tip portion 10b so as to be bent.
