BEST MODE FOR CARRYING OUT THE INVENTION A float 1 of the present invention is provided in a bathtub 20 and a bather sits on the float 1 to take a bath. The vertical guide 2 guides the float 1 in the vertical direction. In the hole 5 or the notch 42 formed in the float 1 in the vertical direction, the column 7
Are penetrated, and the float 1 is guided by the column 7 and moves up and down.

[0007] The roller 8 provided on the float 1 comes into contact with the up-and-down guide means 2 to smoothly move the float 1 up and down. Float 1
Alternatively, the lock means 9 provided on the up-and-down guide means 2 fixes the up-and-down guide means 2 and the float 1 and prevents the float 1 from moving up and down to fix the position.

The upper surface of the floating member 1 is formed as a concave portion 6 having a concave shape, and the height of the seat surface is reduced. When the floating member 1 is submerged, the water depth of the concave portion 6 is increased. The seat 3 formed on the float 1 receives the buttocks of the bather, and the standing part 4
Hold back and back. The buoyancy adjusting means 13 provided on the float 1 adjusts the magnitude of the buoyancy received by the float 1.

The cavity 14 formed in the float 1 stores air or water, and the plug 16 of the buoyancy control means 13 opens and closes the opening 15 of the cavity 14. The buoyancy is adjusted by opening the stopper 16 and changing the ratio of water and air in the cavity 14. The leg 17 of the support 7 is placed on the bottom inside the bathtub 20 and the vertical support 18
Is supported vertically. Leg 17 on the back of float 1
The leg 17 fits into the groove 19 formed at the contact position.

Further, when the float 1 is lowered to the lower limit position, the legs 17 are fitted into the grooves 19 on the lower surface of the float 1 to be in a housed state. Since the float 1 goes down more, the bather's shoulder is soaked in hot water.

The float 1 is lowered to an appropriate position between the upper limit position and the lower limit position, and the lock means 9 is operated and fixed at a suitable position. That is, when the float 1 is moved to a suitable position,
By rotating the knob 11, the base end of the lock pin 10 is pressed against the vertical support 18, and the position of the float 1 is fixed by the frictional force between the two members. When leaving the bath, the locking means 9 is operated to release the above-mentioned fixing. That is, the knob 11 is rotated in the reverse direction, the base end of the lock pin 10 is separated from the vertical support, the float 1 is freely movable from the vertical support, and the lock is released.

The bather raises his buttocks with the power of the lower limbs, the buoyancy received by the bather, and the aid of the buoyancy received by the float 1. At the rising end, the float 1 is locked by the locking means 9.
The bather gets out of the bathtub 20 and ends bathing. In the first embodiment, it is taken out of the bathtub 20 as appropriate. In addition, the support | pillar 7 may be used as a handrail at the time of a bather entering and leaving a bath.

Since the roller 8 is provided with the roller 8 which comes into contact with the up-and-down guide means 2 to smoothly move up and down, the float 1 can be moved up and down smoothly through the roller 8, and when ascending, the buoyancy is sufficiently utilized to reduce the loss thereof. It is easy to rise, which is convenient.

According to the fourth aspect of the present invention, since the lock means 9 for fixing the position of the float 1 is provided, the float 1 can be fixed at an arbitrary height position to take a bath.
Since the float 1 can be firmly fixed to the column 7, even if the bather shifts from the float 1 in the bathtub 20, the float 1 does not incline, and therefore, the bather does not slip off the float 1, and can safely take a bath. It is convenient.

According to the fifth aspect of the present invention, since the center of the upper surface of the float 1 is lowered with the concave portion 6, the portion for supporting the buttocks is thin, and the bather can sufficiently reach the shoulder with hot water. It can be soaked and is convenient.

According to the sixth aspect of the present invention, since the float 1 is composed of the seat portion 3 and the standing portion 4, the buoyancy received by the standing portion 4 is added to the buoyancy received by the seat portion 3. Thus, the buoyancy can be increased without increasing the width and length of the seat portion 3, and a large buoyancy can be obtained, which is convenient.

According to the seventh aspect of the present invention, since the buoyancy 1 is provided with the buoyancy adjusting means 13, the buoyancy can be adjusted according to the individual difference of the bather, and the lifting action of the floater 1 can be taken in the bath. It can be better adapted to the operation and is convenient.

According to the present invention, the buoyancy can be easily adjusted by changing the ratio of water and air in the hollow portion 14 of the float 1 and sealing it with the stopper 16. It is possible and convenient.

According to the ninth aspect of the present invention, there is provided a groove 1 in which the leg 17 is fitted at a position where the leg 17 abuts on the back surface of the float 1.
9 is formed, so that when the float 1 is lowered to the lower limit, the float 1 is lowered to a lower level, and the bather can soak in the hot water to his shoulder, which is convenient.

The rail type vertical guide means 22 in the present invention according to the tenth aspect is configured such that the float vertical groove 23 of the float 1 is fitted to the rail 24 of the bathtub 20,
Since the float 1 is guided in the vertical direction by using the inner wall of the bathtub 20 without using, the struts 7 do not have to be taken in and out of the bathtub 20, which is convenient and convenient.

According to the eleventh aspect of the present invention, the vertical groove type vertical guide means 25 is formed by fitting the floating protrusion 26 of the float 1 into the vertical groove 27 of the bathtub 20. In addition, using the inner wall of the bathtub 20 without using the pillar 7,
Are supported in the up-down direction.
It is not necessary to put the data in and out of 0, which is convenient. Further, since there is no protrusion such as the rail 24 on the inner wall surface of the bathtub 20, there is no obstruction when bathing without using the float 1, which is convenient and convenient.

Since the combination type buoyancy adjusting means 29 according to the present invention adjusts the buoyancy by the number of the floats 28, the coupling of the floats 28 is disassembled when the device is not used. If it is small, the occupied space at the time of storage can be reduced, which is convenient.

According to the thirteenth aspect of the present invention, since the weight type buoyancy adjusting means 33 performs the operation by appropriately mounting the weights 32 mounted on the floats 1, the buoyancy adjustment operation is easy and the amount of buoyancy adjustment can be determined. Easy and convenient.
