Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit bath, and more particularly to a unit bath having multifunctionality suitable for both physically handicapped persons and healthy persons.

[0002]

2. Description of the Related Art Conventionally, in order to assist a physically handicapped person or an elderly person with weak legs (hereinafter referred to as a physically handicapped person) to take a bath, a shower chair (shower chair) or a bathtub is installed in an existing unit bath. The method of attaching a chair etc. later was adopted. There is also known a unit bath in which a part of the upper surface of the edge wall of the bathtub is widened so that a physically handicapped person or the like can easily sit down when going in and out of the bathtub, so that the bath can be bathed smoothly and safely. .

[0003]

However, the method of attaching a shower chair (shower chair) for a physically handicapped person, a chair in a bathtub, etc. after installing a unit bath for the physically handicapped has a problem of poor appearance. However, healthy people have a problem that these facilities get in the way.

In addition, there is a bathtub in which a part of the upper surface of the edge wall is widened, but this is widened only on one of the left and right sides of the bathtub. There are people with a left handicap and people with a right handicap, and it is not possible to deal with such diversity of people with physical disabilities.

[0005]

Therefore, as a result of intensive studies on the above-mentioned problems, the inventor of the present application has attempted to solve the problems mainly from the viewpoint of storage type. That is, the feature of the present invention is that the storage is such that it can be stored in the edge wall inside the bathtub, and the seating portion is fixed at a height intermediate between the bottom of the bathtub and the upper surface of the edge wall of the bathtub during use. The ceremony chair was installed.

As a concrete storage mechanism of the retractable chair,
A simple type is one in which a thin iron plate is attached to the chair body and a magnet with a spring is provided on the storage portion side, a type in which the legs are folded and stored together with the chair body, and a type that uses a fastener.

Further, it is preferable that not only one retractable chair but also a pair of facing edge walls of the bathtub (left and right edge walls of the bathtub) face each other. This is to deal with various persons with physical disabilities.

Further, in addition to the above-mentioned structure of the retractable chair, in the upper surface of the edge wall of the bathtub, the periphery of the portion corresponding to the edge wall in which the retractable chair is provided is smaller than that of other portions. It is preferably wide. This is useful for assisting a series of movements in which the user enters water from the washing place into the bathtub and conversely goes up from the bathtub to the washing place. That is, according to this configuration, when the user enters the bathtub, the user can sit on the upper surface of the edge wall of the bathtub and then move to the retractable chair in the bathtub to ensure safety and use the bathtub. Labor and caregiver effort is significantly reduced. By providing the wide portion of the upper surface of the edge wall of the bathtub on both left and right sides of the bathtub, it is possible to cope with the variety of persons with physical disabilities.

Furthermore, by providing the second retractable chair (shower chair) on the inner wall of the bathroom adjacent to the bathtub, it becomes easy to use the shower at the washing place. Further, since this second retractable chair is provided at the same height as the upper surface of the edge wall of the bathtub, the user enters the bathtub through the upper surface of the edge wall of the bathtub, and the user can enter the bathtub from the bathtub. By using this second retractable chair when moving to the washing area via the upper surface of the edge wall, it is possible to take a safer and smoother bath.
