上記のような従来例をあげると、実公昭49−
20343号公報、実開昭53−101432号公報に示され
る考案がある。 To give a conventional example as mentioned above,
There are ideas shown in Publication No. 20343 and Japanese Utility Model Application Publication No. 53-101432.

円弧形案内条溝が接続されている。 The invention of the first Japanese Utility Model Publication No. 49-20343 has the above-mentioned structure, and the pivot point of the folding door shoji on the hanging hand side which is pivotally attached to the opening frame is connected to the inner peripheral surface of the vertical frame and the opening in the closed position. The curved guide groove provided near the vertical frame is located near the border of the folding door shoji on the hanging hand side that is pivotally attached to the frame, and just outside the external surface of the vertical frame. Following the groove, an outwardly concave curve that gradually deviates toward the outside and an arc-shaped guide groove centered at the pivot point of the folding door shoji on the hanging side are connected to the curve. ing.

アルミ押出型材で製作するのに適しない。 According to this first conventional example, when the folding door shoji is closed, it is stored inside the opening frame and can be rotated 180 degrees from the closed position toward the wall (this conventional example is for a garage and does not have a wall). However, since there is a linear guide groove followed by a curved guide groove that gradually deviates to the outside, the upper and lower frames of the opening frame are usually made of extruded aluminum. In order to attach the members with the curved guide grooves formed on both ends of the straight part of the frame, large notches had to be made at both ends of the upper and lower frames. The parts protrude outward, resulting in an unsightly appearance. That is, it is not suitable for manufacturing the upper and lower frames using extruded aluminum materials.

る。 The second device of Utility Model Application Publication No. 53-101432 is the well-known structure described before the first conventional example, in which the curved guide groove near the vertical frame is connected to the folding door shoji on the hanging side. It is an arcuate guide groove centered on the pivot point. The folding door shoji is placed on the outside of the vertical frame, and the linear guide grooves are provided on the upper and lower frames, and the arcuate guide grooves are provided on the bracket-shaped folding door rotation support part attached to the opening frame. It is set up. Here, the pivot point of the folding door shoji on the pivoting side to the opening frame exists on the extension line of the linear guide groove when viewed from above.

上に折り戸障子の枢着点があるため、開口枠への
枢着側の折り戸障子は竪枠に当る位置が開放する
限度となり、壁面側へは開くことができない。 In this second conventional example, the folding door shoji does not fit within the opening frame, and the appearance is not good. In addition, since the entire load is applied to the parts of the upper and lower frames that protrude outward, a large load is applied to the upper and lower frames when the folding door is opened, so the upper and lower frames must be made strong, and the upper and lower frames protrude outward to a large extent. It has drawbacks such as being heavy. In order to solve this problem, it is possible to house the folding door shoji in an opening frame. However, the linear guide grooves are aligned with the folding door shoji when the folding door shoji is closed, and the pivot point of the folding door shoji is on the extension of the linear guide groove, so the opening frame The folding door shoji on the hinged side can only be opened at the position where it hits the vertical frame, and cannot be opened toward the wall.

へよせられるまでわずかに開く）。 Therefore, if the pivot point of the folding door shoji on the side that pivots to the opening frame is set to the outside of the outer member facing the outside of the vertical frame, if only the folding door shoji on the hanging side is considered, it will rotate all the way to the wall. It seems that it can be opened, but since the pivot point and the linear guide groove are far apart in the forward direction, it is difficult to connect the folding door shoji at the open end and the pivot side to the opening frame from the closed position. The folding door shoji cannot be moved (actually, there is a gap between the linear guide groove and the guide member, so it opens slightly until the guide member is moved to one side by the fitting gap).

を提供することを目的とする。 This invention solves the problems of the conventional example described above. When closed, the folding door shoji is stored inside the opening frame, and it is possible to open the folding door shoji to the outer wall surface outside the opening frame. To provide a folding door for a building that has few outwardly protruding parts and is suitable for manufacturing from aluminum extrusion.
