[Prior Art] Conventionally, a door panel that constitutes a folding door has been assembled in a four-circle frame shape by directly abutting each of the left and right vertical frame members and the upper and lower frame members directly. Since it is necessary to process the end faces, the structure of the door panel is generally known in which the frame members are assembled using the connecting members so that the ends of the frame members can be used without being cut off. .

[Problems to be Solved by the Invention] However, in the door panel assembled by using the above-described connecting member, the adjacent door panels are connected by using separately prepared hinge parts. As the number of parts increases, the hinge parts connecting the door panels must be installed and removed when the folding door is installed or when the folding door is disassembled for repair or cleaning of the door panel. In particular, there is a problem in that the folding door is not easy in the case of a folding door composed of multiple door panels.

On the other hand, since the hanger roller that suspends the folding door is attached to the door panel separately from the above-described folding door connection structure, when the folding door is built into the opening, a plurality of door panels are first installed. In the folded state of the heavy folding door configured by connecting the hinges with each other, the hanger roller on the upper part thereof is sequentially inserted into the guide rail provided along the upper edge of the opening,
In addition to the complicated work, when installing and removing the door panel once installed in the opening, the hinges are combined with the fact that the left and right sides of the opening are separated by the body and side walls. The door panel cannot be attached and detached only by attaching and detaching the door.

The present invention has been made in view of the above circumstances in order to solve the conventional drawbacks, and the purpose thereof is to complete the left and right vertical frames, the upper and lower frames and the connecting member in advance. The folding door can be easily constructed by simply connecting the door panels to each other by connecting the respective half hinges projecting to the one surface side of the connecting member, and the folding door can be built or the door panel can be mounted. An object of the present invention is to provide a hanging and connecting structure for folding doors, which can improve the workability of removal.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the technical means adopted by the present invention are as follows. A connecting member protruding one half hinge to one surface side of the door panel and a connecting member protruding the other half hinge to one surface side of the door panel, respectively, and adjoining between the door panels. By connecting the half hinges of the connecting members to each other with a hinge shaft, a folding door composed of three or more door panels is formed to be bendable, and a hanger roller pivotally supported on the bracket via a vertical shaft is provided at the opening. The interior of the guide rail along the upper edge of the is freely movably mounted, and the hinge shaft located on the base end side of each door panel is integrally attached to the bracket of the hanger roller to suspend the folding door. Characterized by having it Is.

[Advantage of the Invention] Therefore, according to the present invention, each door panel constituting the folding door can be assembled as it is without cutting the end face of the frame, and it is not necessary to separately provide a hinge. The number of parts can be reduced, and the folding door can be easily installed and removed, and the workability can be improved.
