So Therefore, it is not possible to respond to variations in door frame dimensions, and, for example, fixed opening/closing methods cannot be used. When used as a folding door, a large gap is created between the hanging side edge of the door 46 and the door frame. It may happen. A runner that circumscribes the circumferential surface of the roller 44 rolling on the rail as a fixed object. Since the roller 44 is held and fixed by the stopper 42, it can be used as a fixed opening/closing folding door. When in use, the runner 43 tends to move loosely as the door 46 is opened and closed, making it difficult to open and close the door 46. I can't do it smoothly. Further, when the door 46 is closed, the preceding roller 44 may pass through the runner stopper 42 due to excessive force. In this case In this case, the side edge of the door 46 touches and interferes with the door frame during closing, so the door 46, the door frame, and the door An unreasonable force acts on the connector 43.

0004 The purpose of this invention is to allow the runner stopper to be freely adjusted in position relative to the guide rail. By attaching it, the holding position of the runner can be changed to accommodate variations in door frame dimensions. To provide a dual-use folding door with excellent workability. Another purpose of this invention is to fix the runner body that moves linearly along the guide rail. By holding and fixing the runner as a target, the runner can be held and fixed securely. A dual-use type with excellent operability that allows you to open and close the door smoothly. The purpose is to get a folding door.
