When pushed upward, the chain 56 is made to loosen.

As shown in FIGS. 6A and 6B,
When the upper end of the inner cylindrical portion 50 of the second rod 51 reaches the lower end of the first rod 46, the inner cylindrical portion is provided at the lower end of the first rod 46 and the upper end of the second rod 51. A stopper mechanism 57 for locking the 50 to the first rod 46 is provided. That is, a tapered portion 58 is formed at the upper end of the outer cylindrical portion 49 of the second rod 51, and the inner cylindrical portion 50 is formed.
A concave portion 59 is formed in the upper end side wall of the first embodiment. A through hole 60 is formed in a side wall at a lower end portion of the first rod 46, one end of a leaf spring 61 is fixed near the through hole 60, and the other end is formed inside the first rod 46 from the through hole 60.

The stopper pin 62 is inserted into the inner cylinder 9, and the lowering of the inner cylinder 50 is stopped. In this state, the outer cylinder 49 further descends,
The seat 17 reaches near the bottom of the bathtub 11 and stops. Next, when the seat 17 is raised by the hoisting machine 19, the outer cylinder 49 rises. However, while the buoyancy due to bathing water acts on the seat 17, the outer cylinder 49 and the inner cylinder 50 have a friction coefficient. The stopper mechanism 57 stops the movement of the inner cylinder 50 so that the inner cylinder 50 and the first rod 46 do not slide due to rolling friction having a small friction coefficient. Let it be. As a result, buoyancy due to bathing water acts on the seat 17, and the outer tube 49 and the inner tube 50 smoothly slide along the inner tube 50 by sliding friction while the load of the seat 17 is small. Can be slid. The outer cylinder portion 49 is raised, and the tapered portion 58
When the push-up pin 63 is pushed up, the leaf spring 61 is pushed up, the stopper pin 62 is pulled out from the concave portion 59, and the inner cylinder portion 50 becomes in a state where it can be raised by rolling friction,
Both the outer tube 49 and the inner tube 50 can be raised.

Here, a method of using the bathing care device 10 according to the first embodiment of the present invention will be described. (1) The installation part 13 is placed on the opposite side wall 12 of the bathtub 11, and the seat 17 is arranged at the center of the bathtub 11. In this state, the seat 17 is aligned with or slightly above the upper surface of the side wall 12, and the auxiliary seat 17A is
Is placed on the upper part of the side surface 12. (2) The bather is seated on the auxiliary seat 17A from the washing room 11A, and moved to the center of the seat 17 while changing the direction of the bather to the front side of the bathtub 11. (3) The handle 18 is rotated to lower the belt 39 by the hoisting drum 25, and the seat 17 is placed in the bathtub 1 together with the bather.
Put in 1. The auxiliary seat 17A descends while being bent along the side wall 12.

At this time, when the handle 18 is rotated in the direction in which the seat 17 descends, the clutch plate 26 does not rotate because the claw portion 43 meshes with the saw tooth 42, but the male screw portion 28 provided on the drive shaft 27 rotates. The hoisting drum 25 is moved in a direction away from the clutch plate 26 via the female screw portion 23 screwed into the male screw portion 28, and a slip occurs between the hoisting drum 25 and the clutch plate 26, and the seat 17 starts to descend.
The seat 17 has a handle 1 depending on the bather and the weight of the seat 17.
8, the female screw portion 23 relatively rotates the hoisting drum 25 in a direction in which the hoisting drum 25 contacts the clutch plate 26, and moves the hoisting drum 25 to the drum-side friction plate 24.
, The clutch plate 26 is sandwiched between the drive shaft side friction plate 29 and the drum side friction plate 24 to generate friction.
7, free fall is prevented.

It is guided and descends, for example, by 200 mm to the first-stage expanded / contracted state shown in FIG. 7A. Also, the third rod 52 is guided by the second guide roller 53 by the length of the chain 56 inside the first rod 46, and descends and stops.

Further, when the upper end of the inner cylindrical portion 50 of the second rod 51 reaches the intermediate portion of the third rod 52, the outer cylindrical portion 49 slides by sliding friction using the outer periphery of the inner cylindrical portion 50 as a guide. The seat 1 moves further down, for example, 200 mm below the first stage until the second stage shown in FIG.
7 is smoothly lowered into bathtub 11. When the outer tube 49 slides due to sliding friction, the seat 17 enters the bathing water of the bathtub 11 and receives buoyancy.
The load applied to the seat 17 is reduced, the sliding friction between the outer tube 49 and the inner tube 50 is reduced, and the seat 17 can be raised and lowered smoothly. Further, when the bather sits on the seat 17, the moment generated in the telescopic guide 15 is determined by the first guide roller 48 provided on the first rod 46,
Since the second, third, and fourth guide rollers 53, 54, and 55 provided on the third rod 52 support the seat 17, the seat 17 can move up and down smoothly.

(4) When bathing is completed, the handle 18 is rotated to wind up the belt 39 by the winding drum 25, and the seat 17 is raised together with the bather. At this time, since the inner cylindrical portion 50 of the second rod 51 is locked by the stopper mechanism 57, when the load applied to the seat 17 by the buoyancy of the bathing water is reduced, the outer cylindrical portion 49 is rolled inward by the rolling friction. The stopper mechanism 57 is disengaged in a state where the stopper mechanism 57 is disengaged with the upper end of the outer cylinder 49 reaching the upper end of the inner cylinder 50 by smoothly sliding up along the cylinder 50 and rising. And the first rod 46 by rolling friction.
The seat 17 is raised to the upper part of the bathtub 11 by sliding inside. Further, since the clutch plate 26 of the hoisting machine 19 can rotate by pushing up the claw portion 43, the seat 17 can be raised, and when the bather reaches a predetermined position on the upper part of the bathtub 11,
The handle 18 is stopped, the hoist drum 25 is braked by the weight of the bather and the seat 17, and the position of the seat 17 is maintained. (5) In this state, the auxiliary seat 17A is placed on the side 1 of the bathtub 11.
The bather is spread and placed on the upper part of 2, and moves the bather from the seat 17 to the auxiliary seat 17A, and further moves to the washing place 11A. After the bathing of the bather is completed, the seat 17 is folded and overlapped with the backrest 16 so that the bathtub 1 is closed.
1 can be widely used, and a healthy person can take a bath with the bathing care device 10 attached to the bathtub 11.

In this case, if the handle 18 is stopped, the load on the seat 17 causes the hoist drum 25 to
7 is pressed against a clutch plate 26 that rotates only in one direction via a male screw portion 28 provided on the hoisting drum 7 and a female screw portion 23 provided on the hoisting drum 25, and the rotation of the hoisting drum 25 is braked.
