A bathroom folding door having such a barrier-free structure is configured such that a pair of door bodies are foldably opened and closed via a connecting bar in a frame provided at an opening between the bathroom and the dressing room. The lower frame of the frame body is formed so as to have only a level difference with respect to the floor surfaces of the bathroom and the dressing room or to be within a predetermined reference value so as to conform to the standard as a barrier-free structure. .

[0003] In such a bathroom with a barrier-free structure, the door body is arranged so as to rise slightly above the lower frame. That is, in a bathroom folding door without a barrier-free structure, the floor of the bathroom is formed lower than the floor of the dressing room, and a step is formed between the floors. The door body is arranged at a position slightly lower than the lower frame, and when the door body is closed, the side of the door body on the undressing room side is formed to contact the step. On the other hand, in the bathroom folding door of the barrier-free structure as described above, since the lower frame is formed flush or almost flush with the bathroom and the undressing room, the door body has its side face to the lower frame. Was placed without contact.

There is a risk that the water drainage piece will wear out to fulfill its function, cause a large opening / closing resistance, hinder opening / closing properties, or cause unpleasant noise. In order to solve such a problem, it is conceivable to lower the height of the lower frame on the bathroom side so as to have a low step shape so that the water drainage does not contact the lower frame when the door is opened and closed. However, when the lower frame is simply provided with a low step portion on the bathroom side, the latch provided on the connecting bar may not function.

That is, the connecting bar is generally provided with latches at both upper and lower ends thereof, and the latch is removably engaged with the upper and lower frames so that the door can be opened and closed when the door is opened and closed. Producing moderate resistance has been performed. However, as described above, when the bathroom side portion of the lower frame is formed in a low step, the latch provided at the lower end of the connecting bar cannot be engaged with the lower frame, and the latch does not function. there were.

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem in the conventional bathroom folding door, and has a barrier-free bathroom in which a drain piece provided on a door body is not in contact with a lower frame.
