Description

    The present invention relates to a bathtub provided with a handrail and a drain plug, and an open / close bathtub provided with a door portion that includes the handrail and the drain plug and can open and close an opening formed on a side surface of the bathtub body.

Conventionally, for example, in a bathtub for a nursing facility or a household bathtub, if the height of the side wall of the bathtub body is high when taking a bath, it is not easy for a disabled person or an elderly person to cross the side wall, and it is difficult to enter the bathtub. There is a fear. Therefore, the floor surface is dug down to some extent, and the bathtub main body is dropped and installed in the dug portion, thereby reducing the height of the side wall of the bathtub main body relative to the floor surface. Thereby, even if it is a handicapped person, an elderly person, etc., it can be easily bathed across the side wall of a bathtub main body.
However, in the conventional bathtub in which the bathtub main body is dropped onto the floor surface that has been dug, there is a problem that it takes time and construction costs to dug the floor surface to drop the bathtub main body.

Moreover, the bathtub which can open and close shown in patent document 1 is proposed as a bathtub which improved such a fault. In this bathtub, an opening is formed in the side wall of the bathtub body, and a door is provided to be slidable in the vertical direction with respect to the opening. When bathing persons such as disabled people and elderly people take a bath, the door is lowered to open the opening, and a bathing chair on which the bather is placed is placed on the rail base in the bathtub body from the transfer stand arranged adjacent to the bathtub body. It is configured to move sideways and then close the door and close the opening of the bathtub body.
When transferring the bather into the bathtub body during bathing, the amount of hot water in the bathtub above the opening is temporarily transferred to the tank, and after the opening is closed by the door, the hot water in the tank is returned to the bathtub. ing. For this reason, the adjustment of hot water accompanying bathing and leaving the bather is about half of the hot water stored in the bathtub, so that the transfer of hot water accompanying bathing and bathing can be greatly shortened.

By the way, in recent years, the ratio of elderly people to the total population has been increasing year by year, and it has become difficult to care for many elderly people in hospitals, nursing homes, and the like. Therefore, the necessity of care including bathing for the elderly etc. at home is increasing year by year.
However, the open / close bathtub described in Patent Document 1 is configured to transfer a bather to a rail platform in the bathtub through the opening of the bathtub body while being placed on a chair or stretcher for bathing. Since the occupied space including the space for chairs and stretchers is large and a large space is required for the bathroom and the bathtub main body, it is not suitable for bathing in a relatively small domestic bathroom or a small bathroom or bathtub.

On the other hand, in the bathtub described in Patent Document 2, a lift mechanism is provided on the side wall facing the opening of the bathtub body so as to be able to move up and down the seating section on which the bather sits, and the seating section provided on the lift mechanism is rotated. It is made possible and slidable in the direction of the opening. In addition, the lift mechanism is movable along the side wall.
As a result, even in a narrow space such as a home bathroom, the lift mechanism having a seating portion can be moved according to the layout of the bathroom and positioned at a position where bathing is easy. In addition, it is easy for disabled people and the elderly to enter and exit the bathtub through the opening by rotating or moving the seating part while the bather is seated on the seating part of the bathtub. Is possible.
