Field of the Invention The present invention relates to a folding door fixing structure, and more particularly, to a folding door fixing structure in which a plurality of fixing means are arranged at regular intervals in a railing provided on an upper portion of a door frame, A structure in which the hinge member travels on the outer surface of the fixing member and moves naturally from the starting point to the end point after being temporarily stopped at the intermediate point when the rotating member is rotated and opened by folding, The present invention relates to a folding door fixing structure capable of preventing a safety accident that occurs when a user hits a door that moves instantaneously due to a pressing force of a user in the process of opening and closing a door and can improve the durability of the door.

Generally, a folding door that can fully open the doorway is widely applied in recent years in a place where there is no space for completely opening the door outside the doorway of the wall, or for affinity with other surrounding environment.

Such a folding door is provided so as to be slidable along a rail provided on the door frame as well as a plurality of individual doors are rotatably hinged to each other.

Accordingly, the door is sequentially moved and folded by the operation of pushing or pulling the individual door in the lateral direction, thereby opening or closing the door.

The structure of the folding door will be briefly described,

As shown in Fig. 1,

A plurality of doors 2 are arranged in a row and are folded and folded on the basis of the hinge portion 4 in a form of a folding screen. Upper and lower portions of the door frame 1 on which the doors 2 are mounted are provided with guide rails 3 through which the rollers of the door 2 are guided. Accordingly, the doors 2 are slid in the guide rails 3 of the door frame 1 by rollers and sequentially folded or unfolded to open and close the space for installing the folding doors.

However, in opening and closing the folding door 2 having the above-described structure,

The door 2 is moved instantaneously in the process of opening and closing the door 2 by holding the handle and pressing the door 2 so that the accident occurs when the user hits the door 2, There is a problem that an accident is caused by collision with the door 2 and the door 2 moves instantaneously and the one side portion of the door 2 connected to the hinge portion 4 is damaged.
