An outer frame 52 which is attached between the upper and lower prospective surfaces to constitute an outdoor side and has an outdoor side ventilation slit 52a, left and right vertical frames 53 and 54 fixed to both side surfaces of the body frame 51, and an indoor side. It has an operation plate 55 for opening and closing the ventilation slit 511a, and a ventilation path is formed from the outdoor side ventilation slit 52a to the indoor side ventilation slit 511a.

The body frame 51 includes an indoor side wall 511, a downward projection wall 512 extending from the lower outdoor side of the indoor sidewall 511 to the outdoor side, and an outdoor sidewall 513 downwardly extending from the outdoor end of the downward projection wall 512. , an upper projection wall 514 extending from the upper end of the indoor side wall 511 to the outdoor side, and a glass frontage opened downward by the lower portion of the indoor sidewall 511, the lower projection wall 512, and the outdoor sidewall 513. 51a is formed.

Above the indoor side wall 511 of the body frame 51, as shown in FIG. 4, an indoor side ventilation slit 511a is formed over a predetermined range in the horizontal direction to communicate the ventilation path in the ventilation frame unit 5 with the indoor side. At the lower position of the outer frame 52, an outdoor side ventilation slit 52a is formed over the entire length in the left-right direction, which communicates the ventilation path in the ventilation frame unit 5 with the outdoor side.

As shown in FIG. 3, on the outdoor side of the indoor side wall 511 of the body frame 51, an operating plate 55 for opening and closing the indoor ventilation slit 511a is arranged. ) 56 and guide pieces 57 are provided on the indoor side wall 511 .

The operation plate 55 is a plate-shaped member having a rotation shaft 55a in the longitudinal direction of the upper end and a guide pin 55b protruding downward at a predetermined position on the lower end. It is held so as to be rotatable and slidable in the left-right direction.

The guide part 57 is fixed to the outdoor side surface of the indoor side wall 511 so as to match the position where the guide pin 55b of the operation plate 55 protrudes. A groove 57a is formed.

As the knob 56 is slid in the left-right direction, the operation plate 55 moves in the left-right direction without being restricted in rotation. A guide pin 55b provided at the lower end of the guide member 57 is guided by a guide groove 57a formed on the upper surface of the guide member 57 to move indoors and outdoors, thereby rotating the indoor side as shown in FIG. 3(b). Ventilation slit 511a can be opened.
Note that the method of driving the operating plate 55 is not limited to the above.

Two fitting pieces 514a and 514b are formed on the upper surface of the upper projection wall 514 of the body frame 51 on the indoor side and the outdoor side. And two fitting pieces 53a, 53b, 54a, 54b are formed on the outdoor side.

1 and 2, the ventilation frame unit 5 is such that the two fitting pieces 514a and 514b of the upper projection part 514 are inserted into the glass frontage 21a of the upper frame 21 of the inner shoji 2, and the left , the two fitting pieces 53a, 53b, 54a, 54b of the right vertical frames 53, 54 are inserted into the glass frontages 23a, 24a of the left and right vertical frames 23, 24 of the inner shoji 2, and the upper side of the inner shoji 2 is inserted. Panels 25 such as multi-layered glass are attached to the inner peripheries of the glass frontage 51a of the ventilation frame unit 5 and the glass frontages 23a, 24a, and 22a of the left and right vertical frames 23, 24 and the lower frame 22. The inner shoji 2 is composed of these.

The fitting piece 514a formed on the indoor side of the upper projection wall 514 of the main body frame 51 is provided with an airtight material mounting groove 514c opening to the indoor side at the lower part thereof, and the airtight material s is mounted thereon to provide ventilation. The space between the frame unit 5 and the glass frontage 21a of the upper frame 21 is airtight.

In the fittings described above, by mounting the ventilation frame unit 5 using the glass frontage of the frame material of the inner shoji 2, a ventilation device can be easily provided for the shoji.
However, by incorporating the ventilation frame unit 5 into the inner periphery of the frame material of the shoji, in the event of a fire, the resin parts constituting the ventilation frame unit 5 may melt, resulting in the ventilation frame as shown in FIG. 6(a). A gap L<b>1 is generated in the unit 5 .
In addition, due to the difference in the degree of deformation between the frame material of the inner shoji 2 and the ventilation frame unit 5, a gap L2 is generated between the upper frame 21 and the upper part of the ventilation frame unit 5, or as shown in FIG. There is a possibility that a gap L3 may occur between the left vertical frame 23 of the inner shoji 2 and the left vertical frame 53 of the ventilation frame unit 5, degrading the fireproof performance.
In addition, as shown in FIG. 6(a), there is a possibility that a gap L4 is generated between the glass frontage 51a of the ventilation frame unit 5 and the panel 25, degrading the fireproof performance.

The fittings of the present embodiment are improved in fireproof performance by appropriately arranging a heat expansion material on the ventilation frame unit 5 described above. This will be explained below.

In the ventilation frame unit 5 of the fittings of this embodiment, as shown in FIGS. First thermal expansion material f1 to first thermal expansion material f8 are arranged.

As shown in FIG. 3A, the first thermal expansion material f1 is arranged on the upper indoor side of the lower projection wall 512 of the main body frame 51 over the entire length in the longitudinal direction. It faces the lower end from below.
The second thermal expansion member f2 is disposed below the indoor side surface of the outer frame 52 over the entire length in the longitudinal direction, and a portion thereof faces the outdoor side surface of the lower end of the operating plate 55 from the outdoor side.

The third heat expansion member f3 is provided on the indoor side surface of the outer frame 52 at a position facing the resin knob (operation unit) 56 provided on the indoor side wall 511 of the body frame 51 .

Therefore, when a fire occurs, as shown in FIG. 6(b), the second thermal expansion material f2 expands from the outdoor side with respect to the lower end portion of the operating plate 55, thereby suppressing the opening of the operating plate 55. , the first thermally expansible material f1 expands with respect to the operating plate 55 from below, so that the gap generated between the operating plate 55 and the indoor side ventilation slit 511a can be closed.

Further, even if the third thermal expansion material f3 expands from the outdoor side toward the resin-made knob (operating portion) 56 provided on the indoor side wall 511 of the body frame 51, the knob 56 is melted by heat. The third heat expansion material f3 can block the hole for attaching the knob formed in the indoor side wall 511 .

As shown in FIGS. 3(a) and 5(b), the fourth thermal expansion member f4 is provided on the upper surface (upwardly viewed surface) of the upwardly projected wall of the body frame 51, facing the outside in the projected direction. .
As shown in FIG. 5, the fifth thermal expansion member f5 is provided on the outer peripheral side prospective surface of the left vertical frame 53 on the meeting side, on the outdoor side in the prospective direction.
As shown in FIG. 5, the sixth thermal expansion member f6 is provided on the indoor side in the viewing direction on the outer peripheral side viewing surface of the right vertical frame 54 on the side of the door.

Therefore, when a fire occurs, the upper frame 21 and the left and right vertical frames 23 and 24 of the inner shoji 2 are deformed. Even if this occurs, the gap can be closed by the expanded fourth to sixth thermal expansion members f4 to f6, as shown in FIGS. 6(b) and 7(b).
In particular, in the glass frontage 23a of the right vertical stile 23 on the meeting side, where large deformation is likely to occur in the event of a fire and the fitting piece is likely to come off from the stile material, the heat expansion material f5 can be provided on the outdoor side of the prospective surface. , the occurrence of the indoor-outdoor gap L3 due to disengagement of the ventilation frame unit 5 can be suppressed.

As shown in FIG. 3(a), the seventh thermal expansion material f7 is arranged in the glass frontage 51a formed below the main body frame 51, and is arranged on the lower surface of the lower projection wall 512 toward the outside in the projection direction. It is oriented downwards.
As shown in FIG. 3A, the eighth thermal expansion material f8 is arranged in the glass frontage 51a formed below the main body frame 51, and extends indoors in the viewing direction on the lower surface of the lower viewing wall 512. It is oriented downwards.

Therefore, as shown in FIG. 6(b), even if the sealing material such as Grecian that holds the panel 25 melts in the event of a fire and a gap L4 is generated, the seventh and eighth thermally expansive materials are expected to remain within the glass frontage 51a. It expands from both sides in the direction and can suppress the occurrence of the gap L4.

As described above, in the fittings of the present embodiment, in the fittings in which the ventilation device is arranged, the communication passage generated in the ventilation device in the event of a fire can be reliably blocked. Fireproof performance can be improved without having to make fireproof specifications.

It goes without saying that the above embodiments do not limit the invention described in the claims, but are treated as examples.
