Must be moved to one end of the opening.At this time, if the two door bodies are in the folding limit posture in which they overlap each other, the folding door easily tilts in the movement direction with respect to the upper and lower guide rails, and this tilting causes the folding posture. There was a drawback that the folding doors would not move smoothly.

A bar that can come into contact with the guided means at both ends can be moved along the lower guide rail through a guided member that is provided so as to be removably fitted to the lower guide rail at both ends. When the two door bodies are fitted together and folded, the two door bodies are prevented from approaching each other within a certain distance by the contact between the both ends of the bar and the guided means at both lower ends of the folding door. The folding door device configured as described above is proposed.

が妨げられるようなことにはならない。As shown in FIGS. 1 and 2, when the two door bodies 1A, 1B are in the unfolded posture A in which the two door bodies 1A, 1B are deployed in a continuous plane to close the opening, the bar 9 is located below the door bodies 1A, 1B. It is in a state of being movable along the lower guide rail 5 on the side. However, when an operation force is applied to the two door bodies 1A, 1B from the above-mentioned deployed posture A so as to pull out the adjacent ends connected to each other by the hinges 2A-2C to the outside, the two door bodies 1A, 1B are each hinge 2A-. It will be folded around the 2C spindle. Then, as shown by the phantom lines in FIG. 1, the two-door main bodies 1A, 1B are
When the 1B reaches the V-shaped posture B of the plan view V, which is a certain angle before the folding limit posture C in which it completely overlaps, as shown by the phantom line in FIG. 3, both abutting ends 12a, 12b of the bar 9 are It abuts the shaft portion of the roller 8 of the guided means 6A, 6B in the two-door main bodies 1A, 1B, and prevents the two-door main bodies 1A, 1B from approaching any further. That is, the two-door main bodies 1A, 1B are not folded to the folding limit posture C beyond the V-shaped posture B in the plan view V, and the both-door main bodies 1A, 1B are maintained while maintaining the V-shaped posture B in the plan view V. Can be moved to one end side of the opening along the guide rails 3, 5. At this time, both guide rails 3,
Engagement point between 5 and both doors 1A, 1B (horizontal axis wheel for suspension)
4A, 4B and the guided means 6A, 6B) are separated from each other by an appropriate distance in the length direction of the guide rails 3, 5, so that the main body of the door that moves
1A and 1B will maintain a normal posture in which they vertically hang down from the upper guide rail 3, and will not tilt in the movement direction and hinder smooth movement.

If both door main bodies 1A and 1B can be folded to the folding limit posture C with 1A and 1B reaching, the opening can be opened to a larger extent to facilitate the loading and unloading of articles. When folding both door bodies 1A and 1B to the folding limit posture C, the bar 9 may be lifted and removed from the lower guide rail 5 in a state where both door bodies 1A and 1B are folded to an appropriate angle.

Further, the guided means for the upper guide rails 3 and the lower guide rails 5 of the door bodies 1A, 1B are not limited to those shown in the embodiment, and for example, the door bodies 1A, 1B are located outside the guide rails 3, 5. When you do, the door body 1A, 1B
The guided device may be a hinged device that is connected with a hinge and that includes a pair of front and rear vertical shaft rollers.

とも出来る。Further, the bar 9 can be configured so that its length can be adjusted. For example, as shown in FIGS. 5 and 6, a bar 9a provided with a guide roller 10a as a guided member below the outer end portion and a bar 9a provided with a guide roller 10b as a guided member below the outer end portion 9b are overlapped with each other, a long hole 13 is provided in one bar 9a along the longitudinal direction, and a screw hole 14 formed in the vicinity of the inner end of the other bar 9b is screwed through the long hole 13 A fastening screw 15 is provided, and by loosening the fastening screw 15, both bars 9a, 9b can be relatively moved in the longitudinal direction, and by fastening the fastening screw 15, both bars 9a, 9b can be fixed to each other. You can do it. In this case, as shown in the drawing, side guides 16a and 16b sandwiching the other bar 9b are continuously provided on both left and right sides of the one bar 9a, and both bars 9a and 9b are bent around the fastening screw 15. Can be prevented.
Of course, two fastening screws 15 can be used for the same purpose.

Since it can be laterally moved along, it is possible to smoothly move the folding door in this folded state. Moreover,
Since only one bar having a guided member that is detachably fitted to the lower guide rails at both ends is required to be fitted to the lower guide rails, the structure is extremely simple and very inexpensive to implement. Not only that, but also the bar can be easily removed from the lower guide rail to allow the folding of the main body of both doors to the folding limit posture.
