A folding door device that holds a folded state at one end of the upper rail body at the time of use, and pulls out the folding door along the upper rail body at the time of use to deploy in a wall shape is known,
The structure is a long rectangular tubular member, a suspension rail having a travel path for guiding the travel of a traveling mechanism provided at each valley fold of the folding door, and rolling provided at each mountain fold of the folding door. At the one end of an upper rail body in which one guide rail having a guide path for guiding the rollers is integrally provided side by side, all the traveling mechanisms are extended in a straight line continuously with the traveling path and in a folded state of the folding door. It has a holding portion for storing and a storing portion for storing all the rolling rollers in the folded state of the folding door, and a holding member that connects this storing portion to the guide path of the upper rail body through a curved passage. It was a single unit.

[0003]

However, according to the conventional folding door device described above, the front-rear width of the holding member corresponds to substantially the width of one panel forming the folding door, and the storage portion and the guide path are formed. Since the continuous curved path is formed by a curve drawn with a radius larger than at least the lateral width of the panel, the holding member becomes large, and the folding roller moves in the large curved path and the folding door meanders. Since it will bend to the side, there was a defect such as impairing the smoothness of the opening and closing operation of the folding door.

[0004]

In order to solve the above-mentioned conventional defects, the present application proposes an upper rail body in which a suspension rail and two inner and outer guide rails are arranged side by side, and a plurality of panels. A folding door that is connected in a folding screen by a hinge, a traveling mechanism that is provided at each side edge portion of the folding door and a connecting portion of each valley fold and that is hung on the suspension rail so that the suspension rail can travel. Of the pair of panels connected in a fold shape, the first guide rail member provided near the valley fold side of the panel located in the folding direction and guided by the inner guide rail is connected in a mountain fold shape. A second guide member provided near one of the pair of panels on the mountain fold side and guided by the outer guide rail, and integrally provided at one end of the upper rail body and linear with the suspension rail. Connected in a shape The holding portion which allows the intervention of all traveling mechanisms and the intervention of all the first guide members located on the valley folding side of the folding door, and the accommodating portion which curves the guide path of the inner guide rail in a continuous arc shape. And a holding member having a second member, and when the folding door moves from the deployed state to the folded state and from the folded state to the deployed state, the second
The guide member is provided with an entrance / exit path for allowing the entrance / exit to / from the outer guide rail. In the above description, in order to smoothly guide the traveling of the lower part of the folding door, the upper rail body is suspended. A first passage and a second passage respectively facing the rail and the inner guide rail, and
A second guide member, which will be described later, when the folding door moves from the unfolded state to the folded state and from the folded state to the unfolded state.
A lower rail body having an entrance / exit path allowing passage into / out of the passage is provided, and guide members guided to the first passage are provided at both side edge portions of the folding door and at respective connecting portions of the valley fold portion. Of the pair of panels connected in a folded shape, a third guide member guided to the second passage is provided near the mountain-folding side of the panel located in the folding direction, and the traveling property is further improved. In order to do so, the guide members each have a rolling roller.

[0005]

In the unused state of the folding door that opens the doorway of the warehouse, all the traveling mechanisms are gathered in the holding portion of the holding member and all the first guide members located on the valley fold side. Is stored in the storage member and each panel is folded in a folding screen, and when attempting to close the doorway from this state, pull the panel at the starting end position of the folding door in the deploying direction The traveling mechanism of moves in the same direction along the suspension rail, and the first guide member provided on the second panel from the starting end located on the valley fold side rolls while being guided by the curved storage portion, The pair of panels connected in a mountain fold shape open in a V shape, and by increasing the opening angle, the first guide member provided on the second panel is guided to the inlet / outlet end of the storage portion, and On the second panel When the two guide members also approach the entrance / exit path and then the opening angle of the pair of panels approaches 180 degrees, the first guide member is separated from the storage portion and is provided in the inner guide rail, and is provided in the second panel. The second guide members respectively enter the outer guide rails through the entrance / exit passages to form a pair of panels in a straight line, and
The second traveling mechanism moves the suspension rail. This time, a pair of panels, which are connected to each other in the third and fourth mountain folds from the starting end, open in a V shape and the first guide member provided in the fourth panel located on the valley fold side is curved and stored. When the opening angle of the first guide member approaches 180 degrees, the first guide member moves away from the entrance / exit end of the accommodating portion and into the inner guide rail.

When opening the doorway from the expanded state of the folding door that closes the doorway, press the panel at the start end position in the opposite direction to the above direction to move the folding door in the expanded state in the folding direction to start the door. Position 1st at the panel position
Before the guide member reaches the entrance / exit end of the curved storage portion, the second guide member first contacts the entrance / exit path. Since this abutment acts as a moving load in the parallel direction of the folding door, a mountain-fold bending force acts on the panel at the end position and the second panel from the end position connected thereto, and this bending action ends. The second guide member provided near the mountain fold side of the panel at the position escapes from the entrance / exit path, and the first guide member provided near the valley fold side of the panel is allowed by being located at the entrance / exit end, Therefore, the first guide member moves into the storage portion, and the traveling mechanism moves in the folding rail in the folding direction to reduce the opening angle of the pair of panels connected in a mountain fold shape. Then, the first guide member provided on the third panel from the end position is guided from the inner guide rail to the inside of the housing, but before the first guide member comes into contact with the housing, the second guide member of the panel is guided. Touches the entrance and exit, so
A pair of next panels linearly connected to this bend in a V-shape at the position of the hinge, and the second guide member provided on the third panel escapes from the entrance / exit path and The provided first guide member moves into the storage section,
This action is similarly performed between the other linearly connected panels, and as a result, the folding door is folded in a folding screen at the position of the holding portion.
