DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure for a bathroom folding door, and more particularly, to a waterproof structure capable of firmly and easily preventing water from entering an end of a sliding door in a closed state.

[0002]

2. Description of the Related Art A bathroom door attached to an entrance opening of a bathroom in a general house or the like basically has a frame formed by upper and lower frames and left and right vertical frames, and forms a vertical frame and left and right vertical frames. It is configured so that it can be freely opened and closed.

[0003] In such a bathroom door, it is necessary to take sufficient waterproofing measures so that water from the bathroom does not enter the undressing room through the gap between the shoji and the frame. In particular, bathroom doors that are barrier-free are designed so that the steps between the bathroom and the dressing room are reduced, so that more robust waterproofing measures are required. As a method for waterproofing, a method generally used in the past is to attach a resilient waterproof member along the four circumferences of the frame, and when the shoji is closed, the frame of the shoji is pressed against the waterproof member. It is to make it.

[0004]

However, the conventional waterproof structure of a bathroom door has the following problems. First, the location where water infiltrates is often lower than the upper and lower central positions of the shoji, but it is useless to provide a waterproof member that extends to above the shoji as in the related art. In particular, in order to enhance the waterproofness, it is desirable to use a waterproof member having good adhesion to a shoji, such as a bead material made of a soft resin material, but such a waterproof member has a large frictional resistance with the shoji. Therefore, the sliding door cannot be opened and closed smoothly due to the resistance, and a loud noise is generated, which may cause discomfort to the user. It has also been proposed to use a mohair material in the form of a brush in order to reduce the frictional resistance and noise, but such a waterproof member is not preferred because of its high cost.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and is intended to provide a robust and inexpensive bathroom door that does not hinder the opening and closing of a shoji by improving only the waterproofing power of necessary parts. The purpose is to provide a waterproof structure.
