Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an interlocking sliding door that opens and closes by interlocking a plurality of sliding doors.
[0002]
[Prior art]
Conventionally, when the opening is opened and closed by three sliding doors, the sliding doors are slidably mounted in the three rail grooves of the rail, and the opening is opened and closed by moving each sliding door.
[0003]
[Problems to be solved by the invention]
However, in the above conventional example, when opening and closing the opening, each sliding door has to be operated, and there is a problem that the opening and closing operation takes time.
[0004]
In recent years, in order to perform this operation easily, there has been proposed a structure in which three sliding doors are opened and closed in conjunction with each other. However, there is a problem in that the interlocking mechanism is visible in appearance and the appearance is deteriorated.
