Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a watertight structure of a bathroom door provided between a bathroom and a dressing room for surely preventing hot water from flowing out from the bathroom side to the dressing room side.

[0002]

2. Description of the Related Art Due to recent demands for barrier-free construction, barrier-free structures have been proposed for bathroom doors provided between bathrooms and dressing rooms even in general houses.
For example, in the case of a folding door, a pair of doors are foldable through a connecting frame so that they can be opened and closed inside a frame provided in the opening between the bathroom and the dressing room. The lower frame is
In order to comply with the standard as a barrier-free structure, it is necessary to form the bathroom and the floor of the dressing room so as to have only a level difference or a level difference within a predetermined standard value.

That is, in a bathroom folding door that does not have a barrier-free structure, the floor of the bathroom is formed lower than the floor of the dressing room, a step is formed between both floors, and the door body is a lower frame. It was arranged at a position slightly lower than the lower side, and was formed such that the side surface of the door body on the side of the undressing room abuts the step portion when the door body is closed. On the other hand, in the bathroom folding door having the barrier-free structure as described above, since the lower frame is formed flush or almost flush with the bathroom or the changing room,
The door body was arranged without contacting its side surface with the lower frame.

[0004]

However, in the conventional bathroom folding door having such a barrier-free structure,
Since the door body is configured so as not to contact the lower frame, there is a problem that a gap is created between the door body and the lower frame, and the watertightness is likely to deteriorate. For this reason, the lower frame of each door is often provided with a draining piece that hangs down from the lower surface of the door frame, and a watertight structure was formed by this draining piece.However, the lower frame has a sufficient watertight structure. I couldn't get it.

Further, since the right and left vertical frames or upper frames of the bathroom door are not provided with a sufficient watertight structure, when the shower is used in the bathroom, the left and right vertical frames or the upper frame of the bathroom door are used. It was difficult to reliably stop the shower water flowing out from the frame. Furthermore, the bathroom door is a folding door,
Although various structures such as hinged doors and sliding doors are adopted,
In particular, since the structure of the folding door tends to be complicated, it is difficult to obtain a reliable watertight structure. Therefore, a more reliable watertight structure has been required for barrier-free bathroom doors.

The present invention has been made in view of the above problems in the conventional bathroom door, and forms a stronger watertight structure as compared with the conventional bathroom door so that the bathroom side to the dressing room side is formed. An object of the present invention is to provide a watertight structure for bathroom doors that can reliably stop the outflow of hot water.
