Claims

[Scope of Claim for Utility Model Registration] (1) In a folding door in which a plurality of door pieces are foldably connected via a joint part and are opened and closed along a curved rail, the bending direction of the joint part is the folding direction. is a curved opening/closing folding door characterized by having a joint part that is slightly bent in the opposite direction. (2) As the joint has a biaxial structure with a shaft and bearings on both sides of the joint, the positions of the protrusions provided on the shaft and bearings to regulate the bending angle should be adjusted so that they can bend in opposite directions. A curved opening/closing folding door according to claim 1 of the utility model registration claim defined in . (3) As the above-mentioned joint part, a joint that connects the door pieces is divided into two parts and connected to each other by a shaft and a bearing, and the joint is given a bending degree in the opposite direction. Curved folding door. (4) The curved opening/closing type folding door according to claim 1, wherein an auxiliary joint is provided on one or both sides of the joint of the joint portion, and a door piece is connected to the joint or the auxiliary joint.
