In general, direct sunlight radiating on the fittings from the outdoor side penetrates much into the periphery of the lower part of the fittings. In addition, when the lower rail is softened by heat from direct sunlight, the lower rail may bend due to the weight of the face material, such as glass, which is housed in the shoji, and the shoji may be deformed. When the shoji is deformed, the state of engagement between the shoji and the frame changes, and there is a risk that the shoji will rattle or come off the frame.

Therefore, the inventor has found a problem of providing fittings capable of suppressing thermal deformation of the lower rail of the shoji.

The fittings of the present disclosure include a frame body having an upper frame, a lower frame, and left and right vertical frames, and having grooves in the upper frame and the lower frame, and the inside of the frame body having the upper crosspiece, the lower crosspiece, and the left and right vertical frames. and a shoji that is held by the upper frame and the lower frame by inserting the upper end and the lower end into the groove, wherein the lower frame is the lower frame of the shoji It has a height that covers the outdoor surface.

The contact piece portions 233 and 243 are narrower than the substrate portions 231 and 241 so as to contact the surface of the shoji 3 on the outdoor side. Sealing portions 234 and 244 are integrally provided at the tips of the contact pieces 233 and 243, respectively, to elastically contact the surface of the shoji 3 on the outdoor side. The vertical frames 23 and 24 are fixed to the inner surfaces of the left and right side portions of the frame 101 by fixing screws SC3 and SC4 passing through the substrate portions 231 and 241, respectively.

The shoji 3 has a frame 30 in which an upper rail 31, a lower rail 32, and left and right vertical frames 33 and 34 are assembled in a rectangular frame. It is constructed by paying As shown in FIG. 3, the upper crosspiece 31 and the lower crosspiece 32 are composed of metal core members 311 and 321, resin cover members 312 and 322 covering the outer sides of the metal core members 311 and 321, and upper end surfaces and lower surfaces of the resin cover members 312 and 322. It is configured by a resin upper end cover member 313 and a resin lower end cover member 323 attached to the end faces. As shown in FIG. 4, the vertical frames 33 and 34 are respectively composed of metal core members 331 and 341 and resin cover members 332 and 342 covering the outer sides thereof.

As shown in FIG. 1, the shoji 3 has a vertical structure in which an upper crosspiece 31 and a lower crosspiece 32 are arranged between left and right vertical frames 33 and 34 . Specifically, the left and right vertical frames 33 and 34 extend over the entire length of the shoji 3 in the height direction. The upper rail 31 and the lower rail 32 are arranged between the left and right vertical rails 33 and 34, and connect the upper end portions and the lower end portions of the vertical rails 33 and 34, respectively. A substantially U-shaped handle 36 is attached to the central portion of the inner surface of the lower rail 32 .

As shown in FIGS. 1, 3 and 5, the lower frame 22 has a height that covers the outdoor side surface 32a of the lower rail 32 of the shoji 3 when viewed from the outdoor side. Specifically, as shown in FIG. 3 , the height h1 of the first hollow portion 221 of the lower frame 22 is equal to the height of the lower beam 32 of the shoji 3 attached to the frame 2 . The upper end surface 221a of the first hollow portion 221 is arranged at substantially the same height as the upper end surface 32b of the lower rail 32 . The glazing channel 351 supporting the lower end of the face member 35 is arranged at substantially the same height as the upper end surface 221a of the first hollow portion 221, or protrudes slightly above the upper end surface 221a.

Due to the first hollow portion 221 of the lower frame 22, the surface 32a on the outdoor side of the lower rail 32 of the shoji 3 is not exposed to the outdoor side. Therefore, the amount of direct sunlight applied to the lower rail 32 is reduced, and thermal deformation of the lower rail 32 is suppressed. Since the height h1 of the first hollow portion 221 of the lower frame 22 is equal to the height of the lower beam 32 of the shoji 3, the panel 35 is not shielded. Therefore, there is no possibility that the amount of light that can be taken into the room by the shoji 3 through the panel 35 is reduced. Furthermore, since the first hollow portion 221 of the lower frame 22 of the present embodiment has a hollow structure and is excellent in heat insulation, the effect of suppressing thermal deformation of the lower rail 32 is improved.
