A folding door A is constructed by being rotatably inserted into 14 holes 15.

Thus, the runners 12 are provided on the upper surface of the end portion of the wide door body 1 opposite to the gear hinge 3 so as to be approximately equal to the distance 1 between the gear hinge 3 and the pivot 10 in the narrow door body 2. By mounting the pivot 11 and the runner 12 on the rail 5a so that the pivot 11 and the runner can freely rotate and move, the wide door body 1 is not located at the end but at the position closer to the gear hinge 3 side than the end, as shown in FIG. In the runner 12, the amount of protrusion from the frame frame 8 is reduced as compared with the case where the runner 12 is rotated with respect to the rail 5a and rotated and folded at the end of the wide door body 1 having a wide width.

In such a case, the wide door body 1 has a width approximately twice that of the narrow door body 2, and the handle 16 is provided, and the lower surfaces of the wide door body 1 and the narrow door body 2 and the end faces on the pivot support connection side. A mohair 17 is provided on the floor so that no space is formed between the floor and the pivot connection point.

FIG. 4 shows a gear hinge 10, and a gear seat 18 is attached to each of upper and lower end surfaces on a pivotally connected side of a wide door body 1 having a wide width and a narrow door body 2 having a narrow width. The gear 20 is integrally attached to the gear 20, and a connecting plate serving as a gear case 21 is interposed between the gear 20 and the gear seat 18 slidably with the gear 20.

Further, in the embodiment, the narrow door body 2 is hung and held on the upper rail 5 via the runner 11, but a rail may be provided below and guided.

[Effects of the Invention] In summary, according to the present invention, the wide door body with a wide width and the narrow door body with a narrow width are pivotally connected by a hinge so as to be freely foldable, and the end of the narrow door body on the side opposite to the hinge. Guides such as runners and pivots are provided on the upper and lower surfaces of the part or on either surface, and the hinges and the covered parts on the narrow door body are covered by the upper and lower surfaces of the end opposite to the hinge of the wide door body or on either surface. Since the guides are set to be approximately equal to the distance between the guides and each guide is built in a guide such as a rail so that the guides can travel freely, when the folding is performed, the wide door body is not from the end but from the end. The amount of protrusion from the frame frame is smaller than that of a folded wide door that pivots at a position closer to the hinge side with respect to a guide such as a rail, and pivots at the end of a wide wide door body. There is an advantage that you can. Moreover, since the guided portion of the wide door body and the fixed portion on the side of the wide door body are connected by a returning means such as a spring, and the returning means is provided along the inside of the guide, it can be folded against the returning means. The opened wide door body is automatically returned by the return force of the return means and can be closed without forgetting it, and the return means such as the spring is provided along the inside of the guide such as the rail. There is an advantage that the returning means is not exposed to the outside and the appearance is not deteriorated.
