Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bathtub, and more particularly, to a bathtub suitable for a physically handicapped person to easily take a bath while riding in a wheelchair.

Conventionally, bathtubs that allow physically handicapped people to easily take a bath while in a wheelchair have been constructed by using a vertical movement mechanism such as a roller chain to move the inner lid inside the bathtub, as seen in Utility Model Application Publication No. 16133/1983. A bathtub that can be moved up and down has been devised. This is a bathtub that is easy to bathe in because if you place a wheelchair or the like on the inner lid, you can freely move up and down the inside of the bathtub. However, although this conventional technique is convenient as described above when the bathtub is located so that the edge of the bathtub and the bathtub washing scene are at the same level, If the edge of the bathtub is installed at a higher level than the bathroom washing area, it may be difficult to move from outside the bathtub to the inner lid of the bathtub, and the above advantages may not be utilized. Ta.

The present invention has been developed in view of these points, and its gist is that in a bathtub in which an inner lid that moves up and down by a vertical movement mechanism is disposed inside the bathtub,
A washing area plate is arranged outside the bathtub, the inner lid and the washing area plate are connected by a U-shaped connecting member that straddles the bathtub, and the inner lid and the washing area plate are moved up and down in synchronization with the vertical movement mechanism. This is a bathtub characterized by the fact that the bathtub can be easily and safely placed on the inner lid of the bathtub or from the inner lid even when the edge of the bathtub is located higher than the washing area. To provide a bathtub that can be moved outside, thereby allowing a physically handicapped person to take a bath easily and safely while in a wheelchair, and also to provide a bathtub that can be moved outside and inside the bathtub. To provide an interesting bathtub where one can take a bath while enjoying the up-and-down movement by means of moving means.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show a first embodiment. In the figures, 1 indicates a bathtub, and an inner lid 3 that is moved up and down by a vertical movement mechanism 2 is disposed inside the bathtub. In the illustrated example, the vertical movement mechanism 2 is a roller chain type disposed inside the bathtub 1. That is, two shafts 4a, 4b, 4c, upper and lower are provided on one side and the other side of the bathtub 1, respectively.
4d is horizontally installed rotatably, two sprockets 5 are arranged on each shaft, and a roller chain 6 is arranged between the sprockets located above and below. The output of the electric motor 7 is transmitted to the shafts on one side and the other side via a reduction gear 8, a bevel gear 9, and a power transmission shaft 10.

The present invention first provides a bathtub 1 in such a product.
A washing area board 11 is provided outside. The inner lid 3 and the wash area plate 11 are connected by a U-shaped connecting member 13 that straddles the wall 12 of the bathtub 1. In this case, the size of the connecting member 13 is determined so that the inner lid 3 can descend to near the bottom of the bathtub 1 without any hindrance.

Next, one method of use will be explained, taking as an example a case where a person with a physical disability takes a bath while riding in a wheelchair.
Normally, the inner lid 3 and the washing area plate 11 are located at the lowest position. Therefore, the wheelchair can be easily moved onto the wash area board 11. Next, the electric motor 7 is driven by operating a switch (not shown). By driving the electric motor 7,
The output is transmitted to the shafts 4b and 4d on one side and the other side via the reducer 8, bevel gear 9, and power transmission shaft 10. Accordingly, as the roller chain 6 placed between the sprockets rotates, the inner lid 3 begins to move upward. This upward movement of the inner lid 3 is caused by the washing area plate 1 connected to the inner lid 3 via the connecting member 13.
1, the washing area plate 11 also moves upward. When the washing area plate 13 reaches approximately the upper limit height of the bathtub 1, a limit switch (not shown) is activated and the electric motor 7 is stopped. Alternatively, the electric motor 7 is stopped by manually switching it off. In the stopped state, both the washing area board 11 and the inner lid 3 are located approximately horizontally at the upper limit of the bathtub 1, so the wheelchair can be freely moved from the washing area board 11 side to the inner lid 3 side. Can be moved. Once the movement has finished, the electric motor 7 is reversed to lower the inner lid 3. This allows you to take a bath. When getting out of the bathtub 1, the user just needs to perform the opposite operation to the above.

In the above-mentioned embodiment, an example was shown in which the inner lid 3 and the wash area plate 11 were set at the same height.
The inner lid 3 may be moved in stages, or other mechanisms may be used as the mechanism for moving the inner lid 3 up and down. Furthermore, in the above example, the washing area plate 1 is placed outside the wall surface, which is not the wall surface side where the vertical movement mechanism 2 is arranged.
1 is shown, however, as shown in FIGS. 4 and 5, the washing area board 11 may be arranged outside the wall surface side where the vertical movement mechanism 2 is arranged.

As detailed above, this idea connects the inner lid that moves up and down and the washing area plate outside the bathtub, and allows the inner lid and washing area plate to move up and down in synchrony, so that the edge of the wall of the bathtub becomes the washing area. Even if it is located at a higher position, it can be easily and safely moved onto the inner lid of the bathtub, or from the inner lid to the outside of the bathtub. Moreover, it is possible to provide a bathtub in which one can safely take a bath, and also to enjoy the up-and-down movement when taking a bath, making it possible to provide a bathtub that is full of interest.
