い。As described above, the method of projecting the overhanging edge and the projection abutting a part of the periphery of the door body inside the opening to be opened and closed is to narrow the opening to be opened and closed. There are drawbacks that can interfere with getting in and out of articles, especially in the case of walk-in type storage,
It is not possible to project such a projection on the floor surface.

恐れもある。In the case of a folding door in which two door bodies are foldably connected by hinges, the positions of both ends of the folding door are hinged to the side frame of the opening to be opened / closed and a roller unit engaging with a guide rail. Since it is decided, it seems that it is not particularly necessary to determine the position of the folding door intermediate bending part in the closed state where the folding door is deployed, but people fall from the outside to the middle folding part of the folding door in the closed state. When the hand is touched, the middle bent portion of the folding door bends inward, and the appearance is unstable and not only unfavorable, but also the hinges connecting both doors are forcibly broken. There is fear.

ことができる。According to the folding device such as a folding door of the present invention which can be implemented as described above, when the door body moving inward and outward with respect to the opening to be opened / closed is closed to the closing position, the door body is closed. The ascending and descending locking body of the locking device attached to the lower end is moved up and down by the magnetic attraction force between the magnet attached to the lower end and the locked member made of the magnetic plate on the floor side. Since the lower end of the locking body is fitted into the recessed step of the locked member on the floor side and prevents the door main body from moving inward beyond the closed position, Even when an external force that presses the door main body inwardly acts, the door main body can be securely held at the closed position without bending inward.

なくなり、見栄えも良くなる。In addition, it is not necessary to provide a projection protruding toward the opening side of the locked object attached to the lower side of the opening to be opened and closed. The lower or upper side of the opening can be made substantially flat, and there is no need to provide an overhang around the opening to receive the door body. Therefore, it is possible to ensure the maximum size of the opening in which the door body is opened and closed, and in particular, such that articles to be taken in and out of projections protruding from the lower floor surface or the upper top surface of the opening are caught. There is no inconvenience, and in the case of the walk-in type storage box, there is no danger that a person who gets in and out of the storage box will be stuck on the above-mentioned projection, particularly a projection provided on the floor plate surface, and the appearance will be improved.
