The well nut 65 may be provided at another location if necessary.

The first chamber side plate 66 is connected to the first chamber outer plate 64 via the first step portion 68, and is arranged at a position slightly higher than the first chamber outer plate 64. The first indoor side plate 66 is arranged on the indoor side of the protruding piece 26c of the opening lower frame 26 and above the lower frame 32. A slight gap 70 is formed between the frame inner prospective surface 32a of the lower frame 32 and the lower surface of the first indoor side plate 66. The cap 71 is put on the outer plate 64 of the first chamber from above. A lower frame first decorative plate 72 is provided above the cap 71. The lower frame first decorative plate 72 covers the cap 71 and the projecting piece 26c.

The first chamber side plate 66 is provided with two mounting holes 66a near the center and two mounting holes 66b at positions sandwiching the mounting holes 66a. A screw B is inserted into each of the two mounting holes 66b and screwed into a pilot hole (not shown) of the lower frame 32. As a result, the first connector 60 is more firmly fixed to the lower frame 32. Female threads are formed in the two mounting holes 66a that are closer to the inside of the frame.

The second connector 62 is arranged at the position of the notch 50d of the protruding piece 50 in the puffer lower frame 38. The second connecting tool 62 includes a second chamber outer plate 74, a second chamber side plate 76, and a second step portion 78. The second chamber outer plate 74 is a plate piece that protrudes toward the interior from the upper end of the second step portion 78. The outer plate 74 of the second chamber has substantially the same expected dimensions as the protruding piece 50 of the puffed lower frame 38. The second chamber outer plate 74 is provided with two elongated holes 74a. The elongated hole 74a is long in the prospective direction. The elongated hole 74a is provided corresponding to the mounting hole 66a of the first connector 60. The lower surface of the second chamber outer plate 74 is in contact with the upper surface of the first chamber side plate 66 of the first connector 60.

A screw B4 is inserted into each of the two elongated holes 74a and screwed into the mounting hole 66a to fix the first connecting tool 60 and the second connecting tool 62. Since the screw B4 is inserted into the elongated hole 74a, the position of the second connector 62 can be adjusted in the prospective direction. The screw B4 may project slightly downward from the lower surface of the first chamber side plate 66 of the first connector 60, but since a gap 70 is formed between the first chamber side plate 66 and the lower frame 32. The screw B4 does not interfere with the lower frame 32. Therefore, the position of the second connector 62 can be easily adjusted. Further, the number of pilot holes provided in the lower frame 32 can be reduced.

The second step portion 78 is a portion connecting the second chamber outer plate 74 and the second chamber side plate 76. The second step portion 78 forms a step in the vertical direction. The second stepped portion 78 is in contact with the outdoor side finding surface of the puffed lower frame 38 at least in part. The second step portion 78 is provided with two mounting holes 78a.

The second indoor side plate 76 is a plate piece protruding from the lower end of the second step portion 78 toward the indoor side. The second indoor side plate 76 has substantially the same expected size as the rectangular tubular body 48 of the puffed lower frame 38, and is in contact with the outer prospective surface of the rectangular tubular body 48 at least in part. The second indoor side plate 76 is provided with a mounting hole 76a. A screw B is inserted into the mounting hole 76a, and the second connecting tool 62 and the puffed lower frame 38 are fixed by screwing into the lower hole of the frame outer side prospective surface of the rectangular cylinder 48. The second indoor side plate 76 of the second connecting tool 62 acts as a lower support portion that supports the frame outer prospective surface of the puffed lower frame 38. As is understood from FIG. 7, the connecting tool 24 can be simply and sufficiently made small, and does not deteriorate the design of the fitting 12.

Screws B5 are inserted into the two mounting holes 48b of the rectangular cylinder 48. The screw B5 penetrates the rectangular cylinder 48, is inserted into the mounting hole 78a of the second step portion 78, and is further screwed into a pilot hole (not shown) of the lower frame 32 to form the second connecting tool 62 and the lower frame 32. Is fixed.

Screws B6 are inserted into the two mounting holes 48c of the rectangular cylinder 48. The screw B6 is screwed into a pilot hole (not shown) of the lower frame 32 and presses the reinforcing wall 48e against the lower frame 32, so that the puffy vertical frame 42a is fixed to the vertical frame 36a.

Returning to FIG. 5, the construction procedure of the puffer frame mounting structure 10 will be described. First, the first chamber outer plate 64 of the first connector 60 is screwed to the protruding piece 26c of the opening lower frame 26 and the lower frame 32.

Next, the puffed vertical frames 42a and 42b on both sides are fixed to the puffed lower frame 38. That is, the screw B1 is inserted from the mounting hole 52d and screwed into the screw hole 48d. As a result, the puffed lower frame 38 and the puffed vertical frames 42a and 42b are strongly fixed, and the weight of the shoji 23a and 23b is supported not only by the puffed lower frame 38 but also by the puffed vertical frames 42a and 42b. That is, the load capacity of the puffed lower frame 38 is further improved, resulting in high strength. The puffed upper frame 40 (see FIG. 2) is attached to the upper ends of the puffed vertical frames 42a and 42b to form the puffed frame 22.

Next, the second connecting tool 62 is fixed to the swivel lower frame 38. That is, the second connector 62 is arranged at a predetermined position in the notch 50d, and the screw B is inserted from the mounting hole 76a (see FIG. 7) and screwed into the pilot hole of the lower frame 38.

After that, the puffing frame 22 is positioned with respect to the opening frame 16 and the frame 20. That is, the convex portion 48 g of the rectangular cylinder 48 in the puffed lower frame 38 is brought into contact with the indoor side finding surface of the lower frame 32, and the puffed vertical frames 42a and 42b are aligned with the vertical frame 36a and 36b.

Further, the lower surface of the second chamber outer plate 74 of the second connector 62 is brought into contact with the upper surface of the first chamber side plate 66 of the first connector 60. Then, the screw B4 is inserted from the elongated hole 74a and screwed into the mounting hole 66a of the first chamber side plate 66 in the first connecting tool 60 to fix the first connecting tool 60 and the second connecting tool 62. As described above, according to the elongated hole 74a, the puffer frame 22 can be arranged at an appropriate position regardless of the size of the frame 20 in the prospective direction. Further, the above-mentioned screws are inserted and screwed into a predetermined position to fix the puffing frame 22 to the opening frame 16 and the frame 20. After that, the extension frame 21, the vertical decorative plate 56, the lower frame first decorative plate 72, the lower frame second decorative plate 51, and the lower cap 58 are attached at predetermined positions.

According to the puff frame mounting structure 10 and the fitting 12, a separate reinforcing square pipe and a reinforcing bracket that support the puff lower frame 38 from below are unnecessary, and the construction is easy. Further, since the connecting tool 24 is a small part and is arranged so as not to be conspicuous and visually recognizable, the puffer frame mounting structure 10 and the fitting 12 are excellent in design.

Further, since the puffer lower frame 38 is fixed to the opening lower frame 26 and the lower frame 32 by the connecting tool 24, it has sufficient strength against the own weight of the shoji screens 23a and 23b and other external forces. Specifically, as shown in FIG. 8, the puffed lower frame 38 is fixed to the lower frame 32 by the screw B6, but the puffed lower frame 38 is lowered or lowered by an unexpected external force or the like only by fastening the screw B6. There is a concern that it will tilt.

However, in the puff frame mounting structure 10 and the fitting 12, since the puff lower frame 38 is fixed to the frame inner prospective surface of the opening lower frame 26 via the connecting tool 24, it is possible to suppress descent and inclination. Further, since the puffed lower frame 38 includes a protruding piece 50 that abuts on the frame inner prospective surface of the lower frame 32 and a convex portion 48 g that abuts on the indoor side finding surface of the lower frame 32, the lower frame 32 has a lower frame 32. On the other hand, it is stable.

The elongated hole 74a for adjusting the position of the first connecting tool 60 and the second connecting tool 62 in the prospective direction may be provided in the first connecting tool 60. In this case, the first chamber side plate 66 may be arranged on the second chamber outer plate 74.

The connector 24 may be integrally configured with the puff lower frame 38, but by making it a separate body, the puff lower frame 38 is formed of an aluminum alloy to reduce the weight, and the connector 24 is formed of steel. It is possible to secure the strength. Further, the connecting tool 24 has a degree of freedom in dimensions by being separated from the puffer lower frame 38, and can be miniaturized. The fixing means between the connecting tool 24 and the puffed lower frame 38 is not limited to screwing, and may be engaged such as a snap fit. The frame 20 may be omitted. In this case, the puffer frame 22 may be directly attached to the opening frame 16.

In the puff frame mounting structure according to the present invention, the puff frame is attached to the first frame, which is an opening frame provided at the opening of the skeleton, when the second frame, which is a new opening frame, is provided on the indoor side.
