Description

[Detailed Description of the Invention] [Industrial application field] The present invention provides a sanitary equipment unit such as a bathtub, a toilet unit, and a washbasin unit at a suitable place below the living surface in one living space, and A disabled elderly person or a physically handicapped person can freely and simply stay at home,
In some cases, the present invention relates to a living room structure in which a sanitary facility unit that can use these sanitary facility units is installed under the floor without the assistance of an attendant.

[Conventional technology]

Conventionally, when an elderly or handicapped person takes a bath, a toilet, or a washbasin at home, it is difficult to cross the wall around the bathtub when bathing, or to cross the toilet bowl when using a toilet. In addition, there are things that do not interfere with the healthy person until reaching the place where the sanitary equipment unit such as the bathtub, toilet unit, washbasin unit, etc. is installed. The sanitary unit was unavailable. In particular, for the physically handicapped elderly and the physically handicapped, bathing is essential because it promotes metabolism and improves the maintenance function of the body. Bath facilities for the physically handicapped elderly and the physically handicapped may be provided, for example, in nursing homes and hospitals, but it is difficult to reach this location because of its distance and cost. It cannot be done often. Further, it is difficult to install such equipment in a home where a handicapped elderly person or a physically handicapped person lives because of a problem of installation space, cost, and the like. And this issue should become more prominent in the future when population aging is a concern.

From this situation, for example, as described in Japanese Utility Model Laid-Open No. 61-25890, an opening is formed in a part of the floor of the living room, a lid for opening and closing the opening is provided, and the opening below the opening is provided. A living room structure has been proposed in which a hygiene room partitioned by a casing is formed, and hygiene equipment units such as toilets and baths are arranged in the hygiene room.

In the above-mentioned living room structure, the lid is configured to be opened or closed manually or electrically, and in the case of electrically opening or closing, one side of the lid is rotatably attached to the floor surface and arranged below the opening. There is described an opening / closing means configured to move a screw shaft up and down by an electric motor to lift and rotate a lid body from below at an upper end of a screw end.

As the opening / closing means, Japanese Utility Model Laid-Open No. 61-157640 and Japanese Utility Model Laid-Open No. 62-71235 disclose opening / closing means for opening / closing the lid of an underfloor storage, which guides the lid with a link member. While 1
It is described that a pair of gas stays urges the middle part of the lid body upward to assist the opening / closing operation of the lid body.

[Problems to be solved by the device]

With the living room structure described in Japanese Utility Model Laid-Open No. 61-25890, it is possible for an elderly person or a physically handicapped person to use the sanitary equipment unit with relative ease, and the dead space under the floor is effective. Since the sanitary equipment unit is provided by utilizing it, it is possible to install the sanitary equipment unit in an existing house without reducing the living space, but there are the following problems.

The first problem is that the lid opening / closing means becomes large. That is, the lid can be rotated with a smaller force as the upper end of the screw shaft is separated from the rotation center of the lid, but when the upper end of the screw shaft is separated from the rotation center of the lid, With the lid upright, the screw shaft protrudes upward from the side of the sanitary equipment unit and becomes an obstacle to access the sanitary equipment unit, so place the upper end of the screw shaft near the center of rotation of the lid. It is necessary to arrange them, and the driving means such as an electric motor becomes large.

As a second problem, since the electric motor is arranged below the sanitary equipment unit, it is necessary to form a through hole into which the screw shaft can be inserted in the sanitary equipment unit, which ensures the watertightness of the sanitary equipment unit. However, when a bathtub is provided as the sanitary facility unit, water may leak to the lower side of the sanitary facility unit through the through hole.
However, it is possible to arrange the screw shaft on the upper side of the sanitary equipment unit to ensure the watertightness of the sanitary equipment unit, but it is easy to get water on the motor and the screw shaft, which may cause failure or corrosion. At the same time, problems such as electric leakage occur.

A third problem is that the lid body is held in an upright posture via the screw shaft, so that the lid body may collapse when the user of the sanitary equipment unit leans against the lid body.

On the other hand, when the opening / closing means described in JP-A-61-157640 or JP-A-62-71235 is applied as an opening / closing means for opening / closing the lid of the sanitary equipment unit, the screw shaft and Similarly, the gas stay and the link member are obstacles to entering and exiting the sanitary equipment unit, and because the lid body is lifted from the lower side to open and close, the gas stay and the link member must be arranged on the upper side of the sanitary equipment unit, There are problems such as not being able to ensure sufficient water tightness of the sanitary equipment unit, and when arranging the gas stays and link members above the sanitary equipment unit, it is necessary to ensure sufficient water tightness of the opening / closing means itself. It occurs and is difficult to apply.

[Means for Solving the Problems]

The living room structure in which the sanitary equipment unit according to the present invention is incorporated under the floor is formed by extending substantially horizontally around the surroundings in a suitable place near the wall of one living space in a building, leaving the other as a living surface. Laying of tatami mats or floor materials that form a living surface in the living space from the base surface through the supporting means, and the sanitary equipment unit having at least one of a bathtub, a toilet unit, and a wash basin that is recessed downward inside the supporting surface The support surface and the support surface are substantially level with each other and the upper surface is opened,
A lid body made of tatami mat or floor material that can close the upper opening of the sanitary equipment unit is provided so as to be openable and closable around one side along the lower end of the wall of the living space, and one end is near the open end of the lid body. The locked strip is guided toward the wall part of the living space located near the open end of the raised lid, and the other end of the strip is rolled up to extend the lid. The automatic opening / closing means for opening / closing the body is provided.

In this case, it is a preferred embodiment that the sanitary equipment unit has a bathtub and a toilet unit, which are separately arranged side by side with a partition wall interposed therebetween. In addition, it is a preferred embodiment that the lid is a plywood or a metal plate laminated on the lower surface of the tatami mat.

[Action]

Thus, in the living room structure in which such a sanitary equipment unit is installed under the floor, a physically handicapped elderly person or a physically handicapped person who lives in this living space is
Even if it is difficult to walk to a sanitary equipment unit such as a washbasin unit, it crawls and goes near the sanitary equipment unit, and with its lid open, lie on its back and keep its posture. This is done by sliding from the feet toward the bathtub, toilet unit, and washbasin unit located below the living surface, taking a bath, a toilet or a washbasin. When the sanitary equipment unit is not used, the lid is closed and the upper surface of the sanitary equipment unit is used as a part of the living surface.

Further, since one side of the lid is arranged along the lower end of the wall and the lid is configured to be openable and closable around this one side, the lid can be erected on the front side of the wall. It becomes possible, and even if it leans against the raised lid, the lid does not fall down. Further, the strip having one end locked near the open end of the lid is guided toward the wall portion of the living space located near the open end of the raised lid, and the other end of the strip is guided. Since the automatic opening and closing means for opening and closing the lid by winding and unwinding the lid is provided, it is not necessary to provide a through hole in the sanitary equipment unit as in the case of lifting the lid from below. The water-tightness of the lid can be sufficiently secured, and since the strip is locked at the open end of the lid, the lid can be opened and closed with a relatively small force, and the strip is a sanitary equipment unit. It does not hinder access to or from.
