DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding door, for example, to a folding door provided at a large opening for communicating indoors and outdoors.

[0002]

2. Description of the Related Art In recent years, an external space having a terrace, a balcony (deck), and the like is provided outside a building, and gardening and the like are enjoyed using the external space. This external space is often communicated with a living room space such as a living room in a building. For this purpose, a large opening is provided in the building, and a sash window having a glass shoji is attached to the opening.

[0003] As a sash window, in addition to a sliding window having a plurality of shoji screens, a large folding door capable of opening substantially the entire area of an opening may be employed. The folding door usually has a pair of sliding doors that are rotatably connected. However, some folding doors have a plurality of (for example, two) sliding doors for the large opening as described above.

[0004] Such a folding door for a large opening has, for example, two sets of a pair of sashes to be folded, and each set of sashes is connected to the left and right through a connection frame. In each set of sashes, one sash is connected to the left and right vertical frames of the window frame via hinges or the like. Then, when the pair of sashes are folded, each of the folded sashes and the connecting frame project outwardly (outside folding type).

Further, in order to install an external folding door in a building, a window frame is installed in an opening of the building, and then a pair of sliding doors and a connecting frame assembled in advance are built in the window frame.
At this time, a hinge is attached to one of the pair of sashes (the sash on the hanging side) in advance, and the whole including the one sash is screwed to the vertical frame of the window frame via the hinge.

[0006]

However, since the assembly of each of the sliding doors and the connecting frame is heavy, an operator who supports the entire assembly and an operator who connects the hanging side to the window frame. It is necessary to perform the construction work by two people. In addition, since the posture tends to become unstable when one worker supports the whole, it is not easy for the other worker to position the hinge when screwing it to the window frame, and the shoji and the window frame are not easily aligned. May be in contact with and damaged. As described above, when installing a large folding door, there is a problem that the burden on the worker when setting up the shoji is extremely large and it takes time and effort.

An object of the present invention is to provide a folding door which can reduce the burden on an operator and facilitate the work at the time of installation.

[0008]

A folding door according to the present invention comprises at least a pair of sashes arranged in a window frame and connected in a foldable manner, and one of the pair of sashes is connected via a joint member. A folding door fixed to a vertical frame of a window frame, wherein the vertical frame of the window frame is provided with a temporary placing member for temporarily placing a joint member attached to the one shoji side, and the temporary placing member is The one sash side can be supported via the temporarily placed joint member.

In the present invention, a joint member such as a hinge is temporarily placed on the temporary placing member, and one side of the sliding door, that is, the entire hanging side where the pair of sliding doors are integrated is used as the temporary placing member. The support eliminates the need for a conventional worker who supported the whole, and allows one worker to easily perform the work of setting up a shoji. Also, since the joint member fixed to the vertical frame of the window frame is placed on the temporary placing member, the temporary placing member is provided in accordance with the original fixing position of the joint member, so that the temporarily placed joint member is fixed at the fixed position. And the positioning operation is also facilitated. As described above, the work of setting up the shoji screen can be easily performed by one worker, and the above object is achieved.

[0010] The temporary placing member may be provided with a finding side engaging portion which engages with the joint member to prevent the one shoji side from tilting in the finding direction, and / or It is desirable to provide a prospective side locking portion that locks to prevent the one sash side from tilting in the prospective direction. In such a configuration, since the temporarily placed joint member is locked to each locking portion of the temporarily placed member, there is no concern that the heavy sash side is greatly inclined in the finding direction and / or the looking direction, and the joint member is It becomes difficult to come off from the temporary placing member. Therefore, the hanging side of the shoji is more stably supported, and the workability is further improved.
