Next, the drive unit 3 is driven, the rotary arm 2 is rotated by the drive unit 3, and the platform 1 is lowered into the bath 27 by the rotary arm 2. When the platform 1 is lowered, the rollers 26 rotate while contacting the side walls of the bath 27. The platform 1 descends while moving in the forward direction by the rotation of the rotating arm 2, that is, in the front direction of the bather, but since the moving rail 16 is pulled toward the base by the rail spring 22, it cannot move in the forward direction. Instead, it descends along the inner wall of the bathtub 27 in the base direction. At this time, the moving rail 16 on the platform 1 is descending straight, but when viewed from the platform 1 relatively, it means that it has moved in the base direction of the platform 1.

When the platform 1 is raised, the roller 26 rotates while contacting the side wall of the bath 27, as described above. Although the platform 1 is moved in the forward direction by the rotation of the rotating arm 2, the moving rail 16 is pulled in the base direction by the rail spring 22, so that the rail 16 moves upward along the side wall of the bath 27. . The platform 1 is lifted up, the moving rail 16 is brought close to the passing rail 15, and the same height and straight line are formed. The seat portion 30 is sequentially moved from the moving rail 16 to the passing rail 15 and from the passing rail 15 to the truck side rail. , Finish bathing.

When the platform 1 is moved up from the inner wall of the bathtub 27 when the platform 1 is raised, the moving rail 1
6 is at a predetermined movement limit position, and is prevented from moving backward by a stopper 25 after mounting on a table. Further, the movable rail 16 is prevented from moving forward at a predetermined position by a front stopper 24 with a base.

Although not shown, when the platform 1 is moved above the side wall of the bathtub 27 and the pivot arm 2 is pivoted in the upward direction, the platform 1 makes a substantially circular arc motion and moves backward. Since it is possible to move to the washing place 14 side and stop at that position for transfer, it is sufficient to make the transfer rail 15 short by the amount of moving the platform 1 to the washing place 14 side. If the transfer rail 15 is shortened in this way, the distance from the transfer rail 15 to the moving rail 16 is shortened.

Further, due to the large upward rotation of the rotating arm 2, the platform 1 makes a substantially arcuate movement , rises to the uppermost position of the movement locus, and then moves backward, moving to the washing room 14 side. Then stop. In this way, if the platform 1 is drastically moved to the side of the washing place 14, the transfer rail 15 can be eliminated and the carriage side rail 28 can be brought into direct contact with the moving rail.

It should be noted that the loading platform 1 outside the bathtub 27 is attached to the bathtub 27.
In the case of inserting into the bath, a guide (not shown) for guiding the roller of the moving rail 16 to the inner wall of the bath 27 is provided on the inner wall of the bath 27.

When the bathtub 27 is replaced by an exercise bathtub (not shown) in which a plurality of people can enter at the same time, the entire wheelchair 7 is placed on the platform 1 according to the present invention, and a plurality of trainees enter and leave the exercise bathtub. It is used as an elevator to let you.

[0026]

Since the present invention has the rotating arm 2 for moving the platform 1 up and down, there is no mechanism such as a column for moving the rail up and down in the conventional apparatus inside the bath 27, so There is no concern that the hot water will be polluted with oil, and if the platform 1 is moved upward, the inside of the bathtub 27 can be easily cleaned, and the bathtub 27 can be widely used when a healthy person takes a bath, which is convenient. Also, a pair is provided on the left and right sides of the platform 1.
The upper and lower turning arms 8 and 9 are
As shown in Fig. 1 because it is composed of a frame member bent in a V shape.
As you can see, the upper and lower rotating arms 8 and 9 are connected.
When the output shaft 13 is rotated, the platform 1 is placed in the bathtub 27.
It is possible to make it lower than the above, which is convenient.

According to the present invention , since the left and right rotating arms 10 and 11 support the left and right side portions of the stand 1, the swing of the stand 1 is reduced when the bather is moved up and down or transferred. be able to. Therefore, the anxiety given to the bather can be reduced, which is convenient. Left / right rotating arm 1
Compared with the conventional device of cantilever support, 0 · 11 can reduce the rigidity, which is convenient.

In the present invention , the moving rail 16 is provided on the platform 1, and the movable rail 16 moves up and down together with the platform 1 along the side wall of the bathtub 27, and the platform 1 does not move in the forward direction when the platform 1 moves up and down. Since it does not move as necessary, the dead space associated with the moving rail 16 is small, so the small bathtub 2
Can be installed on 7. Therefore, space saving can be achieved, and since the bathtub 27 can be small in size, there are economic effects such as a reduction in the time required for hot water entering and exiting and energy saving related to the amount of hot water, which is advantageous. Further, the bather's travel distance can be shortened, and the anxiety given to the bather can be reduced.

According to the present invention , the stopper 24 with a stand and the stopper 2 with a stand for stopping the movement of the moving rail 16 at a predetermined position.
5 is attached to the stand 1, so that the stand 1 is the bathtub 2
When it is moved above the side wall of 7, the moving rail 16 stops at the moving end position. If the loading platform 1 is moved upward from the inner wall of the bathtub 27 and then moved backward and stopped,
The transfer rail 15 can be shortened as much as it moves to the rear, and further, the transfer rail 1 can be moved by moving the platform 1 backward a large amount.
5 can be omitted.

The caregiver attaches the seat portion 30 to the carriage side rail 28.
This facilitates a push-in operation or a pull-out operation for transferring between the moving rail 16 and the moving rail 16, which is convenient. Furthermore, if the bed 1 is moved to the washing place 14 side and stopped, the bed 1 will be separated from the bathtub 27, so that there will be no more obstacles when cleaning the bathtub 27, and cleaning will be easier, and it will be easier for the healthy person. It is convenient because the bathtub can be used more widely when taking a bath.
