As shown in FIG. 3, the table 30 has a bottomed rectangular cylindrical shape, and a cylinder mounting portion 31 on which a lifting hydraulic cylinder 41 is mounted and fixed on the bottom surface.
3 is bolted to the side surface of the cylinder installation portion 31, and FIG.
It comprises a control unit installation frame 32 which extends to the left and on which the drive control unit 50 is installed and fixed.

On the other hand, the support frame 90 for fixing the assistance device 20 is fixed to the recess 3 of the floor 2, and as shown in FIG. A fixing portion 91 is fixedly stretched between 5, 6, 7, and 8, and a mounting portion 95 is fixed to the control portion installation frame 32 of the base 30 of the seat driving mechanism 25 by bolt connection. ing.

The fixing portion 91 of the support frame 90 is
Two long strut rods 92, 93 arranged along the two inner walls 6, 8 extending in the longitudinal direction of the recess 3, respectively, of the four inner walls 5, 6, 7, 8 of The short strut rods 94 are provided between the ends of the long strut rods 92 and 93 on the sheet drive mechanism 25 side and bolted to each other.

As shown in FIG. 1, long strut rods 92 and 93 are respectively rotatably screwed to rod-shaped main bodies 92a and 93a and both ends of the main bodies 92a and 93a, respectively.
Protruding members 92b, 92 which protrude toward the adjacent inner walls 5, 7 and can be positioned and are pressed and fixed to the inner walls 5, 7
b, 93b, 93b, and legs 92c, 92c, 93c, 93c abutting on the bottom surface 4 of the recess 3.

As shown in FIG. 3, the short strut rod 94 is rotatably screwed to a rod-shaped main body 94a and both ends of the main body 94a, and can protrude toward the adjacent inner walls 6, 8 to be freely positioned. The protruding members 94b, 94b are pressed and fixed to the inner walls 6, 8, respectively.

The mounting portion 95 comprises two inverted L-shaped members 96 and 97 shown in FIGS. 1 and 3, one end of which is bolted to the short strut 94 of the fixing portion 91 and the other. The end is bolted to the control section installation frame 32 of the table 30 of the sheet drive mechanism 25.

The assistance bathing apparatus 100 has the above configuration.

Therefore, in the assistance bathing apparatus 100 shown in FIG.
Since the support frame 90 for fixing the seat drive mechanism 25 is hidden by the recess 3 in which the bathtub 10 is installed, it is possible to improve the beauty of the bathroom 1 and increase the net available space of the bathroom 1.

The projecting members 92b, 92 of the elongated struts 92, 93 forming the fixing portion 91 of the support frame 90.
b, 93b, 93b, and the projecting members 94b, 94b of FIG. 3 of the short strut rod 94 are projected, so that the support frame 90 is provided with four inner walls 5, 6, 7 of the recess 3 of the bathroom 1 shown in FIG. , 8 in a stretched state, so that the fixing can be firmly performed, whereby the installation of the assistance device 20 in the bathroom 1 can be performed easily and quickly.

Incidentally, the assisting device 20 is provided with the sheet 21 as follows.
Can be performed in the bathtub 10, so that the bather can be easily bathed. That is, first, the seat 21 is placed beside the bathtub 10 and lowered near the floor 2, and a bather is put on the seat 21. Next, as shown in FIG. 1, the sheet drive mechanism 25 is raised and started,
The sheet 21 is raised above the height of the upper end of the bathtub 10, and the sheet 21 is swung in the horizontal direction (the direction of arrow A in the figure) toward the bathtub 10 and moved above the bathtub 10 as shown in FIG. Then, the sheet 21 is rotated in the directions of arrows C and D in the figure, and the direction is made to coincide with the longitudinal direction of the bathtub 10. Next, the seat drive mechanism 25 shown in FIG. 1 is started to descend and the bather is put into the bathtub 10 together with the seat 21.

Further, the assisting device 20 is arranged as follows.
The operation of raising 1 from the bathtub 10 can be performed. First, the seat drive mechanism 25 is raised and started, and the seat 21 is moved up.
Is raised above the height of the upper end of the bathtub 10, and then the sheet 21 is swung horizontally (in the direction of arrow B in the figure) so as to be off the side of the bathtub 10 in FIG. Therefore, the seat drive mechanism 25 shown in FIG. 1 is driven downward to lower the bather together with the seat 21 to the vicinity of the floor 2 beside the bathtub 10.

The speed at which the seat 21 is raised and lowered is
By adjusting the opening ratio of the oil flow path by the solenoid valve 53 of FIG. 3 to change the oil flow rate and controlling the expansion and contraction speed of the lifting hydraulic cylinder 41, the adjustment can be made appropriately.
