The present invention relates to a folding door, and more particularly, a rail through which a roller that moves a door of a folding door slides covers the open upper part of a guide frame installed therein to cover the inside of the guide frame. It relates to a guide frame concealment structure of a folding door using a concealing plate to prevent foreign matter from entering.

A folding door refers to a door that opens when a plurality of individual doors are hinged and folded so that adjacent doors can be rotated. Since the entire wall surface on which the door is installed can be opened, the space can be used widely, so the space is open and expandable. This is high, and the space is separated when the door is closed, so the space can be appropriately utilized according to the situation. In addition, glass can be used for the door to secure the view, but when panels and frames of various materials and colors are used, a different atmosphere and design can be produced.

The folding door has conventionally been used as a substitute for the wall of a building in a commercial space such as a cafe, but recently, as it is installed in various places such as a residential space, an office, or a conference hall (conference hall), the range of use is gradually expanding. For example, if you construct a folding door with a middle door without extending the veranda in an apartment, the heat insulation, windproof, and soundproof effect of the room can be remarkably increased because the door is opened only when necessary. Also, it is installed in the conference hall to accommodate the number of participants. Because the size of the conference hall (conference hall) can be adjusted appropriately, only some seats in the large conference hall are filled and the atmosphere does not feel cool, but the conference hall is full and the heat may feel warm.
