However, such a conventional folding door structure has a structure in which a moving guide roller installed to guide opening and closing of the folding door and a hinge hinge for hinging movement of neighboring individual doors are provided separately from each other, There is a problem.

In addition, the moving guide roller and the hinge hinge are separately formed. When the folding door is opened and closed, the door is shaken due to the separate movement. In severe cases, the door is also sent for warping of the door.

In addition, most of folding doors currently installed in Korea are imported and assembled from foreign countries, so that the unit price is considerably high. Also, the construction time is long, and the guide rail formed on the lower side There is a problem that foreign substances are interfered with the opening / closing operation of the entire folding door.

In particular, in case of products imported from foreign countries, it is extremely difficult to repair or repair damage or damage during use. In the case of the hinge hinge for the hinge pivot motion of each individual door, it is integrated with the outer frame forming the individual door and the doorway And it is considerably inconvenient to separate them at the time of maintenance.

As a prior art for solving the above problems, a folding door structure includes an upper frame having an upper guide rail hole formed on an inner bottom surface thereof, An outer frame having a lower frame formed with guide rail holes and left and right side frames vertically connecting the upper and lower frames; A plurality of intermediate hinge hinges hinged together on opposite sides of the respective doors and the neighboring individual doors so that the individual doors adjacent to the individual doors are hingedly pivoted to be folded out of the outer frame; A hinge part hinged to an upper side of the other side of the other door to which the intermediate hinge hinge is not coupled, a roller part having a plurality of vertical rollers fitted in the upper guide rail hole and slidably moving along the upper guide rail hole, An upper guide roller hinge provided on the upper portion and having a support column on which the hinge portion is provided; A hinge part hinged to the lower side of the other side of the individual door to which the intermediate hinge hinge is not coupled, a roller part having a plurality of horizontal rollers fitted in the lower guide rail hole and slidably moving along the lower guide rail hole, And a lower guide roller hinge provided at a lower portion thereof and having a support column on which the hinge portion is provided; The plurality of individual doors are slidably engaged with the upper guide rail holes by roller portions of the upper guide roller hinge, and are slid to be folded at one side of the outer frame.

The prior art configured as above can not selectively open the folding door, and there is a problem that all the folding doors must be opened in order to open the folding door located at the portion to be opened.

Further, since the folding door that is folded is constructed such that the folding door is folded by the hinge, when the folding door is opened, the load of the folding door is increased so that the folding door can not be worn or the folding door can not be weighted. There is a problem that it is broken.
