Although the bathroom 4 and the changing room 5 are partitioned by the interlocking sliding door 1 in the above-described embodiment, as another embodiment of the present invention, water is scattered from the first room to the second room. The present invention can be advantageously practiced also in order to shut off such an environment, for example, the balcony and the room.

According to the present invention, a frame is provided between the first room such as a bathroom and the second room such as a changing room, and a shoji is provided on the frame so as to be openable and closable. To be Water splashing from the first chamber to the second chamber is blocked by the frame and the shoji. A lower frame auxiliary member is detachably connected to the lower frame body of the lower frame. The surface of the lower frame forms substantially the same plane as the one plane connecting the floor surfaces of the first chamber and the second chamber. As a result, when a physically handicapped person, an elderly person, or the like passes by, it is possible to prevent tripping and the like and pass smoothly and safely. Also,
On the lower frame auxiliary member, a rough anti-slip member extending along the one plane along the opening / closing direction of the shoji is attached so as to face upward. As a result, it is possible to prevent the foot from slipping when the first chamber and the second chamber come in and out, and the anti-slip member is attached to the one plane, so that the foot can be attached to the anti-slip member. Can be prevented from being caught.

According to the present invention, the lower frame body has a base portion provided below a plane connecting the floor surfaces of the first chamber and the second chamber, and one side portion of the base portion near the second chamber. A rising part is formed which is bent upward from and is continuous. The uppermost surface of the rising portion is substantially flush with the one plane. The lower frame auxiliary member has a lower flange, a web, and an upper flange, and the lower flange is connected to the base of the lower frame body. The uppermost surface of each upper flange is substantially flush with the one plane, and thus the upper surface of the lower frame is formed flat along the floors of the first chamber and the second chamber as a whole. .
Therefore, even if the number of shoji is large, it is sufficient to lengthen the base portion of the lower frame body in the width direction according to the number and to provide the same number of lower frame auxiliary members as the number of shoji. Only the frame body may be manufactured in a shape corresponding to the number of shoji screens. As a result, it is possible to reduce the complexity of the configuration and the increase in the number of parts associated with the increase in the number of shoji screens. Moreover, since each shoji can be individually attached and detached by sequentially attaching or removing the lower frame auxiliary member from the first chamber side, a plurality of workers can be used to support the shoji. Can be easily performed without requiring.
