[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In this specification, the "front view direction" refers to the direction along the indoor / outdoor direction of a fixture. The "front view direction" refers to the direction along the surface direction of the glass (surface material) of the fixture, and is a direction perpendicular to the front view direction. The "front view surface" refers to the surface of the fixture facing the outdoor side and the indoor side, respectively, and the "front view surface" refers to the surface of the fixture extending in the indoor / outdoor direction. In the drawings, the outdoor side of the fixture is referred to as "outdoor side X1" and the indoor side of the fixture is referred to as "indoor side X2". The horizontal direction when the fixture is viewed from the front is referred to as "left and right".

[0009] As shown in Figures 1 to 4, the fitting 1 shown in the first embodiment is composed of a frame 2 attached to an opening 11 (see Figure 1) in a building skeleton, and two shoji screens: a fixed shoji screen 3 (shoji screen) located on the outside X1 on one side of the frame 2 in the left-right direction (the left side in Figures 1 and 2), and a sliding shoji screen 4 (shoji screen) located on the inside X2 on the other side of the frame 2 in the left-right direction (the right side in Figures 1 and 2). The fixed shoji screen 3 is fixed to one side of the frame 2 in the left-right direction (the left side in Figures 1 and 2), and is also called a fixed shoji screen. When in the closed position, the sliding shoji screen 4 is located on the other side of the frame 2 in the left-right direction (the right side in Figures 1 and 2), and can slide left and right (horizontally) within the frame 2.

[0010] The fitting 1 of this embodiment is a fitting placed in an opening 11 in the building frame. In this embodiment, the opening 11 is formed as a large opening. For example, in this embodiment, the opening 11 is considered to be a large opening when the height H of the opening is 2500 mm or more. The opening 11 of this embodiment is formed with an opening size of, for example, a height H of about 3500 mm and a width W of about 5000 mm. The sliding shoji screen 4 is configured with, for example, a height H of 3500 mm and a width W of 2500 mm.

[0011] When the opening 11 is a large opening and fittings are placed in the opening 11, the weight of the shoji door of the fittings increases, which increases the burden on the shoji door and the door rollers attached to the shoji door. Therefore, it becomes necessary to ensure the strength of the shoji door and the door rollers.

[0012] The frame body 2 is placed in an opening 11 in the building skeleton. The frame body 2 is formed by framing an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, 24 in a rectangular shape.

[0013] 3 and 4, the upper frame 21 includes a wooden upper frame member 211 and a metal frame member 215 disposed at the upper end of the wooden upper frame member 211. The wooden upper frame member 211 is formed in a rectangular cross section extending in the forward direction and extends in the left-right direction. An upper frame exterior guide groove 213 and an upper frame interior guide groove 214 are provided on the underside of the wooden upper frame member 211.

[0014] As shown in Figure 3, the upper frame exterior guide groove 213 is formed in the range in the left-right direction on the exterior side X1 of the upper frame 21 where the FIX shoji screen 3 is placed. The upper frame exterior guide groove 213 is recessed upward from the underside of the wooden upper frame material 211 and opens downward. An upward protruding plate 3152 formed at the upper end of the FIX shoji screen 3 is placed in the upper frame exterior guide groove 213.

[0015] As shown in Figure 4, the upper frame interior guide groove 214 is formed over the entire left-right area on the interior side X2 of the upper frame 21 from the center in the projection direction. The upper frame interior guide groove 214 is recessed upward from the underside of the wooden upper frame material 211 and opens downward. An upward protruding plate 4152 formed at the upper end of the sliding shoji screen 4 is placed in the upper frame interior guide groove 214, and guides the left-right movement of the sliding shoji screen 4.

[0016] As shown in Figures 3 and 4, metal guide groove frames 2131, 2141 are arranged in the upper frame exterior guide groove 213 and the upper frame interior guide groove 214. Airtight materials 2132, 2142 are attached to interior plate members 2131a, 2141a arranged along the interior X2 surfaces of the upper frame exterior guide groove 213 and the upper frame interior guide groove 214 in the guide groove frames 2131, 2141. An upward protruding plate 3152 formed at the upper end of the fixed shoji screen 3 is arranged in the upper frame exterior guide groove 213 while abutting against the airtight material 2132. An upward protruding plate 4152 formed at the upper end of the sliding shoji screen 4 is arranged in the upper frame interior guide groove 214 while abutting against the airtight material 2142.

[0017] The metal frame material 215 is arranged along the upper surface of the wooden upper frame material 211.

Both the outdoor frame member 2151 and the indoor frame member 2152 are made of a metal material such as aluminum. A connecting member 2153 (bridge member) is arranged between the outdoor frame member 2151 and the indoor frame member 2152. The connecting member 2153 is made of a material with thermal insulation properties such as resin, and blocks the transfer of heat from the outdoor side X1 to the indoor side X2 in the metal frame material 215 of the upper frame 21.

[0018] As shown in FIGS. 3 and 4, the lower frame 22 has a lower frame lower portion 221 and a lower frame upper portion 222 disposed above the lower frame lower portion 221.

[0019] The lower frame lower section 221 is divided into three sections in the front-to-back direction: a lower room exterior frame member 2211, a lower central frame member 2212, and a lower room interior frame member 2213. The lower room exterior frame member 2211, the lower central frame member 2212, and the lower room interior frame member 2213 are formed with a hollow structure having a hollow section. The lower room exterior frame member 2211, the lower central frame member 2212, and the lower room interior frame member 2213 are all metal frame members, and are each made of extruded shapes extruded in the length direction from a metal material such as aluminum.

[0020] A connecting member 2214 (bridge member) is arranged between the lower outdoor frame member 2211 and the lower central frame member 2212. A connecting member 2215 (bridge member) is arranged between the lower central frame member 2212 and the lower indoor frame member 2213. The lower outdoor frame member 2211, the lower central frame member 2212, and the lower indoor frame member 2213 are integrally connected by connecting members 2214, 2215. The connecting members 2214, 2215 are formed from a material with thermal insulation properties such as resin, and block the transfer of heat from the outdoor side X1 to the indoor side X2 in the lower frame lower section 221.

[0021] The lower frame upper section 222 is fixed to the upper part of the lower frame lower section 221. The lower frame upper section 222 is divided into two sections in the front direction, an upper outdoor frame member 2221 and an upper indoor frame member 2222. The upper outdoor frame member 2221 has an outdoor section 2224, a middle section 2225, and an indoor section 2226. The outdoor section 2224, the middle section 2225, and the indoor section 2226 are arranged in this order from the outdoor side X1 to the indoor side X2.

[0022] The outdoor portion 2224, the middle portion 2225, and the indoor portion 2226 are formed in a hollow structure having a hollow portion. The outdoor portion 2224, the middle portion 2225, and the indoor portion 2226 of the upper outdoor frame member 2221, and the upper indoor frame member 2222 are all metal frame members, and are each made of extruded shapes extruded in the length direction from a metal material such as aluminum.

[0023] A connecting member 2223 (bridge member) is arranged between the upper outdoor frame member 2221 and the upper indoor frame member 2222. The upper outdoor frame member 2221 and the upper indoor frame member 2222 are integrally connected by the connecting member 2223. The connecting member 2223 is formed from a material having heat insulating properties such as resin, and blocks the transfer of heat from the outdoor side X1 to the indoor side X2 in the lower frame upper section 222.

[0024] As shown in Fig. 3, the FIX shoji 3 is fixed on one side of the frame body 2 in the left-right direction (the left side in Figs. 1 and 2) in a state in which it is positioned across the upper surfaces of the outdoor part 2224 and the outdoor part X1 of the middle part 2225 of the upper outdoor frame member 2221 of the lower frame upper part 222 of the lower frame 22. A wooden lower wooden member 222a on the FIX shoji 3 side is attached to the upper surface and side of the indoor side X2 corner of the middle part 2225 of the upper outdoor frame member 2221 of the lower frame upper part 222 of the lower frame 22.

[0025] As shown in Fig. 4, the lower frame 22 is formed with a pair of lower frame rails 223, 224 extending in the left-right direction on the indoor side X2. The pair of lower frame rails 223, 224 includes an outdoor lower frame rail 223 arranged on the outdoor side X1 and an indoor lower frame rail 224 arranged on the indoor side X2. The outdoor lower frame rail 223 and the indoor lower frame rail 224 are spaced apart in the projection direction and are formed to protrude upward from the lower frame 22 on the indoor side X2 of the lower frame 22. Door rollers 5 provided at the lower end of the sliding shoji screen 4 are arranged on the pair of lower frame rails 223, 224, and the pair of lower frame rails 223, 224 guide the left-right movement of the sliding shoji screen 4.

[0026] The outdoor bottom frame rail 223 is formed to protrude upward at the indoor side X2 end of the indoor side portion 2226 of the upper outdoor frame member 2221 of the lower frame upper section 222 of the lower frame 22. An airtight material arranging section 2231 protruding toward the outdoor side X1 is formed in a portion of the outdoor bottom frame rail 223 midway up and down near the upper end. The airtight material arranging section 2231 is formed to be C-shaped and open toward the outdoor side X1. An airtight material 2232 is arranged in the airtight material arranging section 2231. The indoor side bottom frame rail 224 is formed to protrude upward at the outdoor side X1 end of the upper indoor side frame member 2222 of the lower frame upper section 222 of the lower frame 22.

[0027] Between the outdoor bottom frame rail 223 and the indoor bottom frame rail 224, a wooden inter-rail wooden lower member 222b is attached to the upper part of the connecting member 2223. A wooden indoor bottom wooden member 222c is attached to the indoor side X2 part of the indoor bottom frame rail 224.

[0028] In the left-right direction of the lower frame 22, in the area where no fixed shoji screen is provided, a cover frame 2227 is attached to the upper surface of the lower frame 22, as shown in FIG.

[0029] As shown in Figure 2, the pair of vertical frames 23, 24 include wooden vertical frame members 231, 241 and metal frame members 235, 245 arranged on the outside of the vertical wooden frame members 231, 241 in the left-right direction (viewing direction). The vertical wooden frame members 231, 241 are formed in a rectangular cross section extending in the viewing direction and extend in the up-down direction (viewing direction). Vertical frame guide grooves 234, 244 are provided on the inside surfaces of the vertical wooden frame members 231, 241 in the left-right direction.

[0030] The vertical frame guide groove 234 of the wooden vertical frame member 231 of the vertical frame 23 is formed over the entire vertical area on the outside X1 side of the wooden vertical frame member 231 of the vertical frame 23. The vertical frame guide groove 234 is recessed outward from the inner surface of the wooden vertical frame member 231 in the left-right direction, and opens toward the inside in the left-right direction. An outer protruding plate 3352 formed on the left side of the FIX shoji screen 3 in the left-right direction is placed in the vertical frame guide groove 234.

[0031] The vertical frame guide groove 244 of the wooden vertical frame member 241 of the vertical frame 24 is formed over the entire vertical area on the indoor side X2 of the wooden vertical frame member 241 of the vertical frame 24. The vertical frame guide groove 244 is formed by being recessed outward from the inner surface of the wooden vertical frame member 241 in the left-right direction, and opens toward the inside in the left-right direction. An outer protruding plate 4452 formed on the right side of the sliding shoji screen 4 in the left-right direction is disposed in the vertical frame guide groove 244. The vertical frame guide groove 244 guides the left-right movement of the sliding shoji screen 4 at the left-right end of the sliding shoji screen 4.

[0032] Metal guide groove frames 2341, 2441 are arranged in the vertical frame guide grooves 234, 244. Airtight materials 2342, 2442 are attached to indoor plate members 2341a, 2441a arranged along the indoor side X2 surface of the vertical frame guide grooves 234, 244 in the guide groove frames 2341, 2441. An outer protruding plate 3352 formed at the left end of the fixed shoji screen 3 in the left-right direction is arranged in the vertical frame guide groove 234 while abutting against the airtight material 2342. An outer protruding plate 4452 formed at the right end of the sliding shoji screen 4 in the left-right direction is arranged in the vertical frame guide groove 244 while abutting against the airtight material 2442.

[0033] The metal frame members 235, 245 are arranged along the outer surfaces of the wooden vertical frame members 231, 241 in the left-right direction. The metal frame members 235, 245 are divided into two parts in the forward direction: outdoor frame members 2351, 2451 and indoor frame members 2352, 2452. The outdoor frame members 2351, 2451 and the indoor frame members 2352, 2452 are both formed from a metal material such as aluminum. Connecting members 2353, 2453 (bridge members) are arranged between the outdoor frame members 2351, 2451 and the indoor frame members 2352, 2452. The connecting members 2353, 2453 are formed from a material with thermal insulation properties such as resin and block heat transfer from the outdoor side X1 to the indoor side X2 at the metal frame members 235, 245 of the vertical frames 23, 24.

[0034] We will now explain the FIX shoji screen 3. As shown in Figures 1 to 3, the FIX shoji screen 3 is constructed by fitting glass 35 made of two pieces of glass plate inside a frame body 30 made up of an upper frame 31, a lower frame 32, a frame-side vertical frame 33 arranged on the left-hand vertical frame 23 side, and a joining vertical frame 34 arranged on the sliding shoji screen 4 side, all assembled into a rectangular shape. As shown in Figure 3, the FIX shoji screen 3 is fixed to one side in the left-right direction within the frame body 2 (the right side in Figures 1 and 2) with its upper end arranged in the upper frame outer guide groove 213 of the upper frame 21 and its lower end arranged on the top surface of the outer side X1 of the lower frame 22.

[0035] The upper frame 31, the lower frame 32, the frame side vertical frame 33 and the joining vertical frame 34 all constitute glass holding parts that hold the end of the glass 35 in the viewing direction.

[0036] The glass 35 is rectangular, has a thickness in the front direction, and extends in the front direction. The glass 35 is fitted and fixed into the frame 30. As shown in Figures 2 and 3, the glass 35 fitted into the frame 30 of the FIX shoji 3 is double-glazed glass that includes a glass sheet 35a on the inside X2, a glass sheet 35b on the outside X1, and a spacer 35c sandwiched between the two glass sheets 35a and 35b at their ends, providing excellent thermal insulation.

[0037] As shown in Figures 2 and 3, the upper frame 31, lower frame 32, frame side vertical frame 33 and joining vertical frame 34 are each mainly composed of a wooden frame body 311, 321, 331, 341 (glass holding body portion) and a fiber reinforced core material 313, 323, 333, 343 provided inside the frame body 311, 321, 331, 341.

[0038] The fiber-reinforced core materials 313, 323, 333, and 343 are arranged outside the end of the glass 35 in the view direction and are provided so as to cover the end of the glass 35 in the view direction. The fiber-reinforced core materials 313, 323, 333, and 343 are made of fiber-reinforced plastic. The wooden stile bodies 311, 321, 331, and 341 are arranged around the fiber-reinforced core materials 313, 323, 333, and 343. The wooden stile bodies 311, 321, 331, and 341 are made of wood (wood). By providing the wooden stile bodies 311, 321, 331, and 341 so that they are exposed to the outside of the upper stile 31, the lower stile 32, the frame-side stiles 33, and the joining stiles 34, it is possible to create a sense of authenticity of wood, such as the texture unique to wood.

[0039] The upper frame 31, the lower frame 32, the frame-side vertical frame 33, and the joining vertical frame 34 are formed with a slim size with a narrow width in the facing direction. In this embodiment, the upper frame 31, the lower frame 32, the frame-side vertical frame 33, and the joining vertical frame 34 have wooden frame bodies 311, 321, 331, and 341 exposed to the outside, and are formed with a width of, for example, about 30 mm to 35 mm. If the width of the upper frame 31, the lower frame 32, the frame-side vertical frame 33, and the joining vertical frame 34 exceeds 40 mm, they tend to give the impression of not being slim, and if the width is narrower than 30 mm, the impression of not being able to express the authentic feel of wood, such as the texture unique to wood, is lost.

[0040] In the FIX shoji 3, the upper frame 31, the lower frame 32, the frame-side vertical frame 33, and the joining vertical frame 34 are each composed of a composite frame structure having wooden frame bodies 311, 321, 331, 341 and fiber-reinforced core materials 313, 323, 333, 343 made of fiber-reinforced plastic. As a result, the FIX shoji 3 has excellent heat insulation properties because the wooden frame bodies 311, 321, 331, 341 and the fiber-reinforced core materials 313, 323, 333, 343 made of fiber-reinforced plastic are made of materials with low thermal conductivity.

[0041] Examples of fiber reinforced plastics include carbon fiber reinforced plastics (CFRP) which use carbon fibers as reinforcing fibers and are impregnated with resins such as thermosetting resins and thermoplastic resins and then hardened, and glass fiber reinforced plastics (GFRP) which use glass fibers as reinforcing fibers.

[0042] The carbon fiber reinforced plastic is formed by bundling multiple fibers extending in the longitudinal direction of the upper frame 31, the lower frame 32, the frame-side vertical frame 33, and the joining vertical frame 34, impregnating the fibers with a resin such as a thermosetting resin or a thermoplastic resin, and hardening the bundled fibers. By aligning the direction in which the multiple fibers that make up the carbon fiber reinforced plastic extend with the longitudinal direction of the upper frame 31, the lower frame 32, the frame-side vertical frame 33, and the joining vertical frame 34, heat can easily move along the longitudinal direction of the upper frame 31, the lower frame 32, the frame-side vertical frame 33, and the joining vertical frame 34, and heat is blocked in the forward direction, thereby improving thermal insulation.

[0043] Furthermore, in order to reduce the possibility of breakage along the direction of the fibers when the direction in which the multiple fibers that make up the carbon fiber reinforced plastic extend is aligned with the longitudinal direction of the upper frame 31, lower frame 32, frame side vertical frame 33, and joining vertical frame 34, the surface of the bundle of multiple fibers that make up the carbon fiber reinforced plastic may be covered with a fibrous material (for example, a cloth such as a nonwoven fabric) whose fibers extend in a different direction.

[0044] In addition, in this embodiment, the extending direction of the multiple fibers constituting the carbon fiber reinforced plastic is configured to coincide with the longitudinal direction of the upper frame 31, the lower frame 32, the frame side vertical frame 33, and the joining vertical frame 34, but this is not limited to this, and the extending direction may be configured not to coincide with the longitudinal direction of the upper frame 31, the lower frame 32, the frame side vertical frame 33, and the joining vertical frame 34. Furthermore, the multiple fibers constituting the carbon fiber reinforced plastic do not have to pass from end to end in the longitudinal direction of the upper frame 31, the lower frame 32, the frame side vertical frame 33, and the joining vertical frame 34.

[0045] The carbon fiber reinforced plastics constituting the fiber reinforced core materials 313, 323, 333, and 343 have an elastic strength equal to or greater than that of a glass plate. In this specification, elastic strength refers to Young's modulus, and the Young's modulus of a glass plate is approximately 71,600 MPa. The Young's modulus can be measured in accordance with the general rules prescribed in JIS K 7161, in accordance with either JIS K 7164 (isotropic and orthotropic fiber reinforced plastics) or JIS K 7165 (unidirectional fiber reinforced plastic composites).

[0046] In the glass holding portion that holds the end of the glass 35 in the viewing direction, fiber reinforced core materials 313, 323, 333, 343 are arranged so as to cover the end of the glass 35 in the viewing direction, so that the glass holding portions of the upper frame 31, lower frame 32, frame side vertical frame 33 and joining vertical frame 34 can be given the strength to hold the glass 35 and thermal insulation can be ensured.

[0047] The upper frame 31 will now be described in further detail. As shown in Figure 5, the upper frame 31 has a wooden frame body 311 arranged at the upper end of the glass 35 in the viewing direction, a fiber-reinforced core material 313 arranged inside the frame body 311, and a metal frame material 315 arranged at the upper end of the upper frame 31.

[0048] The fiber reinforced core 313 is arranged to cover the upper end of the glass 35. The fiber reinforced core 313 has a core front-direction extension plate 3131 (first portion) extending in the front direction, a pair of L-shaped inward protruding portions 3132 (second portion) protruding downward in the vertical direction (inward in the front direction) along the front surface of the glass 35 from the end portion of the core front-direction extension plate 3131 on the indoor side X2 and the end portion on the outdoor side X1 in the front direction, and a pair of outward extending portions 3133 (second portion) extending upward in the vertical direction (outward in the front direction) from the end portion of the core front-direction extension plate 3131 on the indoor side X2 and the outdoor side X1 in the front direction.

The enclosing member 3411 and the interior-facing-side inner member 3412 are made of wood (lumber). The enclosing member 3411 and the interior-facing-side inner member 3412 may be entirely separate or integrally formed, or the enclosing member 3411 and the interior-facing-side inner member 3412 may be separated along the way.

[0091] The enclosing member 3411 has a front-direction extending portion 3411a extending in the front-direction, a front-direction inward extending portion 3411b extending from the outside-side X1 end of the front-direction extending portion 3411a to the left in the left-right direction, and an indoor-side extending portion 3411c extending from the left-side end of the front-direction inward extending portion 3411b to the indoor-side X2.

[0092] The projection direction extending portion 3411a extends in the projection direction along the right-hand side surfaces of the U-shaped hook portion 3435 of the fiber reinforced core material 343, the core material projection direction extending plate 3431, and the outward protruding plate 3434, so as to cover the right-hand side surface of the U-shaped hook portion 3435 of the fiber reinforced core material 343, the right-hand side surface of the core material projection direction extending plate 3431, and the right-hand side surface of the outward protruding plate 3434. The inward extending portion 3411b in the front view direction extends in the front view direction along the outside X1 surface of the outward protruding plate 3434 of the fiber reinforced core material 343 and the outside X1 surface of the inner extending plate 3432a of the L-shaped inward protruding portion 3433 so as to cover the outside X1 surface of the outward protruding plate 3434 of the fiber reinforced core material 343 and the outside X1 surface of the inner extending plate 3432a of the L-shaped inward protruding portion 3433. The inside extending portion 3411c extends along the left side surface of the protruding plate 3432b of the L-shaped inward protruding portion 3433 of the fiber reinforced core material 343 so as to cover the left side surface of the protruding plate 3432b of the L-shaped inward protruding portion 3433 of the fiber reinforced core material 343.

[0093] The indoor-facing-direction inner side member 3412 is arranged on the left side in the left-right direction at the end side of the indoor-facing-direction extending plate 3431 of the fiber-reinforced core 343 on the indoor-facing side X2.

[0094] When the right end of the glass 35 is positioned so that it is covered by the U-shaped portion 346, on the indoor side X2 of the right end of the glass 35 in the horizontal direction on the open side of the U-shaped portion 346, a sealant 347 is arranged between the indoor side X2 visible surface of the right end of the glass 35 and the outdoor side X1 surface of the tip side of the inward protrusion 3432 of the fiber-reinforced core material 343 and the outdoor side X1 surface of the indoor side visible direction inner side member 3412 of the frame body 341, and on the closed side of the U-shaped portion 346, a backup material 348 is arranged between the sealant 347 and the left side in the horizontal direction of the core material forward direction extension plate 3431 of the fiber-reinforced core material 343. At the open side of the U-shaped section 346, at the exterior side X1 of the right end of the glass 35, a sealant 347 is arranged between the exterior side X1 surface of the right end of the glass 35 and the interior side X2 surface of the protruding plate 3433b of the L-shaped inward protruding portion 3433 of the fiber-reinforced core 343 and the interior side X2 surface of the interior extending portion 3411c of the enclosing member 3411. At the closed side of the U-shaped section 346, a backup material 348 is arranged between the sealant 347 and the left side surface of the core-inward extending plate 3431 of the fiber-reinforced core 343. Note that a glazing channel may be used for the sealant 347.

[0095] The sliding shoji screen 4 will now be described. As shown in Figures 1, 2, and 4, the sliding shoji screen 4 is constructed by fitting two panes of glass 45 inside a rectangular frame body 40 made up of an upper frame 41, a lower frame 42, a frame-side vertical frame 43 located on the right-hand vertical frame 24 side of the frame body 2, and a joining vertical frame 44 (vertical member) located on the fixed shoji screen 3 side. The upper end of the sliding shoji screen 4 is placed in the upper frame room-side guide groove 214 of the upper frame 21, and the lower end is engaged with a pair of lower frame rails 223, 224 of the lower frame 22 so as to be movable in the left-right direction. The lower frame 42 of the sliding shoji screen 4 is provided with a door roller 5 that rolls on the pair of lower frame rails 223, 224 of the lower frame 22.

[0096] The upper frame 41, the lower frame 42, the frame side vertical frame 43 and the joining vertical frame 44 all constitute glass holding parts that hold the end of the glass 45 in the viewing direction.

[0097] The glass 45 is rectangular, has a thickness in the front direction, and extends in the front direction. The glass 45 is fitted and fixed in the frame 40. As shown in Figures 2 and 4, the glass 45 fitted in the frame 40 of the sliding shoji screen 4 is a double-glazed glass that includes a glass sheet 45a on the inside X2, a glass sheet 45b on the outside X1, and a spacer 45c sandwiched between the two glass sheets 45a and 45b at their ends, and has excellent thermal insulation properties.

[0098] As shown in Figures 2 and 4, the upper frame 41, lower frame 42, frame side vertical frame 43 and joining vertical frame 44 are each mainly composed of a wooden frame body 411, 421, 431, 441 (glass holding body portion) and a fiber reinforced core material 413, 423, 433, 443 provided inside the frame body 411, 421, 431, 341.

[0099] The fiber reinforced core materials 413, 423, 433, and 443 are arranged outside the end of the glass 45 in the find direction and are provided so as to cover the end of the glass 45 in the find direction. The fiber reinforced core materials 413, 423, 433, and 443 are made of fiber reinforced plastic. The frame bodies 411, 421, 431, and 441 are arranged around the fiber reinforced core materials 413, 423, 433, and 443. The wooden frame bodies 411, 421, 431, and 441 are made of wood.

[0100] The upper frame 41, the lower frame 42, the frame-side vertical frame 43, and the joining vertical frame 44 are formed with a slim size with a narrow width in the facing direction. In this embodiment, the upper frame 41, the lower frame 42, the frame-side vertical frame 43, and the joining vertical frame 44 have wooden frame bodies 411, 421, 431, and 441 exposed to the outside, and are formed with a width of, for example, about 30 mm to 35 mm. If the width of the upper frame 41, the lower frame 42, the frame-side vertical frame 43, and the joining vertical frame 44 exceeds 40 mm, they tend to give the impression of not being slim, and if the width is narrower than 30 mm, they give the impression of not being able to express the authentic feel of wood, such as the texture unique to wood.

[0101] The sliding shoji screen 4 has an upper frame 41, a lower frame 42, a frame-side vertical frame 43, and a joining vertical frame 44, each of which is made of a composite frame structure having a wooden frame body 411, 421, 431, 441 and a fiber-reinforced core material 413, 423, 433, 443 made of fiber-reinforced plastic. As a result, the sliding shoji screen 4 has excellent heat insulation properties because the wooden frame body 411, 421, 431, 441 and the fiber-reinforced core material 413, 423, 433, 443 made of fiber-reinforced plastic are made of materials with low thermal conductivity.

[0102] As the fiber reinforced plastic, the same fiber reinforced plastic as that described for the upper frame 41, lower frame 42, frame side frame 43 and joining frame 44 of the FIX shoji screen 3 can be used.

[0103] In the glass holding portion that holds the end of the glass 45 in the view direction, fiber reinforced core materials 413, 423, 433, 443 are arranged so as to cover the end of the glass 45 in the view direction, so that the glass holding portions of the upper frame 41, lower frame 42, frame side vertical frame 43 and joining vertical frame 44 can be given the strength to hold the glass 45 and thermal insulation can be ensured.

[0104] The upper frame 41 will now be described in further detail. As shown in Fig. 4, the upper frame 41 has a wooden frame body 411 arranged at the upper end of the glass 45 in the viewing direction, a fiber-reinforced core material 413 arranged inside the frame body 411, and a metal frame material 415 arranged at the upper end of the upper frame 41. The upper frame 41 has the same configuration as the upper frame 31 of the FIX shoji screen 3 shown in Fig. 5 described above, and therefore the description of the upper frame 41 will be omitted and the description of the upper frame 41 will be omitted.

[0105] The details of the bottom frame 42 will be further explained. As shown in Fig. 8, the bottom frame 42 has a wooden frame body 421 arranged at the lower end of the viewing direction of the glass 45, a fiber-reinforced core material 423 (strength member) arranged inside the frame body 421, and two door rollers 5 arranged at the lower end of the bottom frame 42. As shown in Fig. 1, the two door rollers 5 are provided at both ends in the left-right direction at the lower end of the sliding shoji screen 4.

[0106] The bottom frame 42 differs from the bottom frame 32 of the FIX shoji screen 3 described above mainly in that the roller 5 is positioned below the fiber-reinforced core material 423. Therefore, the explanation of the bottom frame 42 will mainly focus on the roller 5, and the same components as those of the bottom frame 32 of the FIX shoji screen 3 shown in Figure 5 described above will be omitted by assigning corresponding reference numerals, or the explanation of the bottom frame 32 of the FIX shoji screen 3 shown in Figure 5 described above will be used and omitted.

[0107] 8, the door roller 5 is disposed below the fiber reinforced core material 423 that is disposed below the lower end of the glass 45. The door roller 5 is disposed between the pair of outward extending portions 4233 in the front direction on the underside of the core material front-direction extending plate 4231 (first portion) of the fiber reinforced core material 423.

[0108] The core material front-side extending plate 4231 has a glass lower end positioning plate 4231a arranged within the thickness range of the glass 45, and a pair of outer extending plates 4231b (outer extending portions) extending from both ends of the glass lower end positioning plate 4231a in the front-side direction to the interior side X2 and the exterior side X1. The pair of outer extending plates 4231b are formed to extend outward in the front-side direction (indoor side X2, outdoor side X1) beyond the interior side X2 and outdoor side X1 facing surfaces of the glass 45 in the thickness direction at the lower end of the glass 45.

[0109] The door roller 5 has a wheel support frame 51 (reinforcement portion) and a two-row wheel configuration portion 52 in which two rows of wheel portions 521, 522 are provided in the projection direction, and multiple sets of the two rows of wheel portions 521, 522 are arranged side by side in the left-right direction. The two rows of wheel portions 521, 522 are arranged at the lower end of the bottom frame 42 (glass holding portion) that holds the lower end of the glass 45. The two rows of wheel portions 521, 522 are arranged below a fiber-reinforced core material 423. The fiber-reinforced core material 423 is arranged above the two rows of wheel portions 521, 522 of the door roller 5 that are arranged separately on the indoor side X2 and the outdoor side X1, straddling the two rows of wheel portions 521, 522 in the projection direction. In this embodiment, as shown in FIG. 1, the door roller 5 has two rows of wheel portions 521, 522 arranged in four sets side by side in the left-right direction.

[0110] 8, the two rows of wheel parts 521, 522 are arranged below the visible surface of the lower end of the glass 45, sandwiching a fiber reinforced core material 423 arranged below the visible surface of the lower end of the glass 45, at a position in the visible direction where the glass 45 is arranged. The two rows of wheel parts 521, 522 are arranged separately on the outside side X1 and the inside side X2 in the visible direction below the visible surface of the lower end of the glass 45.

[0111] The two rows of wheel portions 521, 522 are rotatably arranged on the upper end of the outdoor lower frame rail 223 and the outdoor lower frame rail 223 formed on the lower frame 22. The outdoor lower frame rail 223 and the indoor lower frame rail 224 are arranged apart in the forward direction.

[0112] The wheel support frame 51 is formed below the fiber-reinforced core material 423, extending in the front-to-rear direction. The wheel support frame 51 supports two rows of wheel sections 521, 522 and, by being located below the fiber-reinforced core material 423, reinforces the bottom frame 42. The wheel support frame 51 is divided into two sections in the front-to-rear direction: an outdoor frame section 511 (outdoor-side reinforcement section) and an indoor frame section 512 (indoor-side reinforcement section). Both the outdoor frame section 511 and the indoor frame section 512 are formed from a metal material such as aluminum. A connecting member 513 (bridge member) is disposed between the outdoor frame section 511 and the indoor frame section 512. The connecting member 513 is formed from a thermally insulating material such as resin and connects the outdoor frame section 511 and the indoor frame section 512. The connecting member 513 is located below the fiber-reinforced core material 423.

[0113] The connecting member 513 blocks heat transfer from the outdoor side X1 to the indoor side X2 of the wheel support frame 51 of the door roller 5. A fiber reinforced core 423 (strength member) is arranged above the connecting member 513. Therefore, even if the connecting member 513 is made of resin, the connecting member 513 is provided below the fiber reinforced core 423, and therefore, by arranging the fiber reinforced core 423 above the connecting member 513, the strength of the wheel support frame 51 can be ensured.

[0114] The outdoor frame part 511 is formed to open downward, and has the wheel part 521 of the outdoor side X1 arranged inside. A downward extension piece 514 that protrudes downward is formed at the end of the outdoor side X1 of the outdoor frame part 511. An airtight material 2232 attached to an airtight material arrangement part 2231 that protrudes toward the outdoor side X1 from a part of the outdoor side lower frame rail 223 of the lower frame 22 midway in the vertical direction near the upper end part is abutted against the downward extension piece 514. The indoor frame part 512 is formed to open downward, and has the wheel part 522 of the indoor side X2 arranged inside.

[0115] The frame-side stile 43 will now be described in further detail. As shown in Fig. 2, the frame-side stile 43 has a wooden stile body 431 located at the end on the right side of the glass 45 in the left-right direction (the other side in the viewing direction), and a fiber-reinforced core material 433 located inside the stile body 431. The frame-side stile 43 has the same configuration as the frame-side stile 33 of the FIX shoji screen 3 shown in Figs. 2 and 6, but with the left and right reversed, and therefore the explanation of the frame-side stile 43 will be omitted and the explanation of the frame-side stile 33 of the FIX shoji screen 3 shown in Figs. 2 and 6 will be used.

[0116] The details of the joining vertical frame 44 will be further described. As shown in Fig. 7, the joining vertical frame 44 has a wooden frame body 441 arranged at the end on the left side of the glass 45 in the left-right direction (one side in the viewing direction), and a fiber-reinforced core material 443 arranged inside the frame body 441.

[0117] The joining stile 44 is configured by rotating the joining stile 34 of the FIX shoji screen 3 shown in Fig. 7 by 180° and then arranging the airtight material arrangement frame 4413 and the inside facing member 4412 in the part where the inside facing member 3412 was arranged. Therefore, in explaining the joining stile 44, parts with the same configuration as the joining stile 34 of the FIX shoji screen 3 shown in Fig. 7 will be assigned the corresponding symbols and explanations will be omitted.

[0118] An airtight material arrangement frame 4413 (airtight material arrangement portion) is fixed to the outside-side X1 portion of the inward protrusion 3432 on the right side of the end portion on the indoor side X2 of the core material projection direction extension plate 4431 (first portion) of the fiber-reinforced core material 443 of the joining vertical frame 44, and an indoor side projection direction inner side member 4412 is fixed to the right side of the airtight material arrangement frame 4413 in the left-right direction. The airtight material arrangement frame 4413 is arranged on the core material projection direction extension plate 4431 side of the fiber-reinforced core material 443, and the indoor side projection direction inner side member 4412 is arranged to the right of the airtight material arrangement frame 4413 in the left-right direction. The airtight material arrangement frame 4413 is made of metal, such as aluminum. The airtight material arrangement frame 4413 may also be made of resin.

[0119] An airtight material 4413a is attached to the outside X1 surface of the airtight material arrangement frame 4413. When the sliding shoji screen 4 is in the closed position, the airtight material 4413a abuts against the inside X2 surface of the U-shaped hook portion 3435 of the joining vertical frame 34 of the fixed shoji screen 3.

[0120] When the sliding shoji screen 4 is in the closed position, the U-shaped hook portion 4435 of the joining vertical frame 44 is hooked onto the U-shaped hook portion 4435 of the joining vertical frame 34 of the fixed shoji screen 3. As a result, when the sliding shoji screen 4 moves from the open position to the closed position, the sliding shoji screen 4 is restricted from moving to the right in the left-right direction from the position where the U-shaped hook portion 4435 of the joining vertical frame 44 is hooked onto the U-shaped hook portion 4435 of the joining vertical frame 34 of the fixed shoji screen 3. This makes it possible to prevent the sliding shoji screen 4 from colliding with the frame-side vertical frame 24 (see FIG. 2) that is arranged on the right side in the left-right direction of the frame body 2.

[0121] The fitting 1 of the first embodiment has the following effects.

[0122] The fitting 1 of this embodiment includes glass 35, 45 and a glass holding portion (upper frame 31, lower frame 32, frame-side vertical frame 33, joining vertical frame 34, upper frame 41, lower frame 42, frame-side vertical frame 43, joining vertical frame 44) that holds the end of the glass 35, 45 in the front direction. The glass holding portion has frame bodies 311, 321, 331, 341, 411, 421, 431, 441 and fiber-reinforced core materials 313, 323, 333, 343, 413, 423, 433, 443 made of fiber-reinforced plastic. The fiber-reinforced core materials 313, 323, 333, 343, 413, 423, 433, 443 have first portions (core material front-direction extension plates 313, 323, 333, 343, 413, 423, 433, 443) that extend along the front direction. 131, 3231, 3331, 3431, 3631, 3731, 3831, 4231, 4431), and a second portion (the L-shaped inward protruding portion 3132) extending along the protruding direction from the first portion (core protruding direction extending plate 3131, 3231, 3331, 3431, 3631, 3731, 3831, 4231, 4431). Direction extending plate 3132a, outward extending portion 3133, upper inward extending plate 3232a of L-shaped inward protruding portion 3232, outward extending portion 3233, inner side of L-shaped inward protruding portion 3332 It has a side extending plate 3332a, an outwardly extending portion 3333, an inwardly protruding portion 3432, an inwardly extending plate 3433a of the L-shaped inwardly protruding portion 3433, and an outwardly protruding plate 3434).

[0123] Therefore, since the fiber-reinforced core materials 313, 323, 333, 343, 413, 423, 433, and 443 are made of fiber-reinforced plastic, thermal insulation is ensured. Furthermore, the fiber-reinforced core materials 313, 323, 333, 343, 413, 423, 433, and 443 have members extending in both directions, that is, the first portion extending along the projection direction and the second portion extending along the projection direction, so strength can be more reliably ensured. This improves the strength of the glass holding portions (upper frame 31, lower frame 32, frame-side vertical frame 33, joining vertical frame 34, upper frame 41, lower frame 42, frame-side vertical frame 43, and joining vertical frame 44) while ensuring thermal insulation performance. As a result, the strength of the glass holding part can be improved, and in fittings 1 placed in large openings 11, the visible width of the frame of the shoji (fixed shoji 3, sliding shoji 4) can be reduced, realizing slimmer frames. This improves the design.

[0124] In this embodiment, the fiber-reinforced core materials 313, 323, 333, 343, 413, 423, 433, 443 are arranged to cover the end portions of the glass panes 35, 45 in the find direction, and have U-shaped portions 316, 326, 336, 346, 416, 426, 436, 446 that cover the end portions of the glass panes 35, 45 in the find direction. This allows the fiber-reinforced core materials 313, 323, 333, 343, 413, 423, 433, 443 to be easily supported by the U-shaped portions 316, 326, 336, 346, 416, 426, 436, 446 covering the end portions of the glass panes 35, 45 in the find direction.

[0125] In this embodiment, the fiber-reinforced core 423 provided at the lower end of the glass 45 has a glass lower end arrangement plate 4231a of the core extension plate 4231 arranged along the lower end of the glass 45, and a pair of outer extension plates 4231b extending outward from the visible surface of the glass 45 in the thickness direction of the glass 45. As a result, even when the load of the glass 45 is applied to the lower end of the glass 45, the pair of outer extension plates 4231b of the core extension plate 4231 can distribute and bear the load of the glass 45 on the outside X1 and inside X2 sides in the thickness direction of the glass 45, thereby suppressing deformation of the lower end of the sliding shoji screen 4.

[0126] In this embodiment, the sliding shoji screen 4 has a wheel support frame 51 arranged at the lower end thereof, and the wheel support frame 51 has an outdoor frame portion 511, an indoor frame portion 512, and a connecting member 513 arranged between the outdoor frame portion 511 and the indoor frame portion 512, and the connecting member 513 is provided below the fiber-reinforced core material 423. In this way, by connecting the outdoor frame portion 511 and the indoor frame portion 512 with the connecting member 513, it is possible to improve the heat insulating performance, and since the fiber-reinforced core material 423 is arranged above the connecting member 513, it is possible to ensure strength in the portion where the connecting member 513 is arranged.

[0127] In this embodiment, the frame bodies 311, 321, 331, 341, 411, 421, 431, 441 are made of wood. As a result, by providing the frame bodies 311, 321, 331, 341, 411, 421, 431, 441 with fiber-reinforced core materials 313, 323, 333, 343, 413, 423, 433, 443 to ensure strength, even if the frame bodies 311, 321, 331, 341, 411, 421, 431, 441 are made of wood to increase the amount of wood used to create a sense of authenticity, the visible width of the frame of the shoji (fixed shoji 3, sliding shoji 4) in the fittings 1 placed in the large opening 11 can be reduced, and the frame can be slimmed down while still creating a sense of authenticity.

[0128] In this embodiment, the joining vertical frame 44 has an airtight material arrangement frame 4413 fixed to the frame body 441, and the airtight material arrangement frame 4413 is made of metal or resin. By making the airtight material arrangement frame 4413 out of metal or resin, which is less likely to deform or deteriorate than wood, it is possible to reliably maintain airtightness. Furthermore, by making the airtight material arrangement frame 4413 out of metal or resin, it is easier to process than if the airtight material arrangement frame 4413 were made of wood.

[0129] The building fixture 1 of this embodiment comprises glass 45, a door roller 5 which is provided at the lower end of the glass 45 in the viewing direction and has two rows of wheel portions 521, 522 spaced apart in the viewing direction, and a fiber-reinforced core material 423 as a strength member which is arranged between the door roller 5 and the glass 45 and straddles the two rows of wheel portions 521, 522.

[0130] Therefore, by providing a door roller 5 having two rows of wheel portions 521, 522 spaced apart in the projection direction, the two rows of wheel portions 521, 522 allow the sliding shoji screen 4 to travel stably while reducing the projection width of the bottom frame 42, thereby enabling the bottom frame 42 to be slimmer. Furthermore, by providing a fiber-reinforced core material 423 as a strength member between the door roller 5 and the glass 45, the fiber-reinforced core material 423 can support the weight of the glass 45, ensuring strength. This provides the strength to support heavy glass. Note that in this embodiment, the fiber-reinforced core material 423 as a strength member is provided between the door roller 5 and the glass 45. However, when a strength member is provided between the door roller 5 and the glass 45, the strength member is not limited to the fiber-reinforced core material 423. Any member capable of ensuring strength may be used as the strength member.

[0131] In this embodiment, by configuring the fiber reinforced core material 423 with fiber reinforced plastic, it is possible to ensure high strength while ensuring high heat insulation properties.

[0132] Next, the bottom frame 42A of the sliding shoji screen 4A of the second embodiment will be described. As shown in Fig. 9, the configuration of the bottom frame 42A of the sliding shoji screen 4A of the second embodiment is mainly different from the configuration of the bottom frame 42 of the sliding shoji screen 4 of the first embodiment shown in Fig. 8. In the second embodiment, the same components as those in the first embodiment are designated by the same reference numerals and descriptions thereof will be omitted.

[0133] As shown in Figure 9, the lower frame 42A has a wooden frame body 721 arranged at the lower end of the viewing direction of the glass 45, a fiber-reinforced core material 723 (strength member) arranged inside the frame body 721, and a door roller 6 arranged at the lower end of the lower frame 42A.

[0134] The fiber-reinforced core material 723 has a core material front-direction extension plate 7231 (first part) extending in the front direction, and a pair of L-shaped inward protrusions 7232 (second part) protruding from the end portion on the indoor side X2 and the end portion on the outdoor side X1 in the front direction of the core material front-direction extension plate 7231 to the upper side in the vertical direction (inside the front direction) along the front surface of the glass 35.

[0135] The pair of L-shaped inward protrusions 7232 each have an upper inner extending plate 7232a (second portion) extending upward in the vertical direction (inward in the sight direction) from both ends in the sight direction of the core material sight direction extending plate 7231, and a pair of outer extending plates 7232b (outer extending portions) extending from the upper end (inner end in the sight direction) of the upper inner extending plate 7232a to the indoor side X2 (outside) or the outdoor side X1 (outside) in the sight direction of the glass 45. The pair of outer extending plates 7232b are formed to extend outward in the sight direction (indoor side X2, outdoor side X1) beyond the indoor side X2 sight surface and the outdoor side X1 sight surface of the glass 45 in the thickness direction at the lower end of the glass 45.

[0136] The U-shaped U-section 726, which opens upward and is formed by the core material projection direction extension plate 7231 of the fiber-reinforced core material 723 and a pair of upper inner extension plates 7232a of a pair of L-shaped inward protrusions 7232, is positioned to cover the lower end of the glass 45, and covers the indoor side X2 and outdoor side X1 surfaces of the lower end of the glass 45 and the projection surface of the lower end.

[0137] By positioning the lower end of the glass 45 so that it is covered by the U-shaped portion 726, in the vertical direction, the lower end of the glass 45 is positioned between a pair of upper inner extending plates 7232a of a pair of L-shaped inward protrusions 7232 in the forward direction, with the lower end surface (forward surface) extending in the forward direction of the lower end being positioned on the upper surface of the core material forward direction extending plate 7231.

[0138] The pair of upper inner extension plates 7232a are arranged along the visible surface on the indoor side X2 and the visible surface on the outdoor side X1 at the lower end of the glass 45. Therefore, the pair of upper inner extension plates 7232a can support the lower end of the glass 35 in a state where they are along the visible surface on the indoor side X2 and the visible surface on the outdoor side X1 at the lower end of the glass 45.

[0139] The wooden frame body 721 is arranged around the fiber reinforced core material 723 so as to cover the fiber reinforced core material 723. The wooden frame body 721 has an L-shaped indoor side member 7211 arranged on the indoor side X2 of the lower end of the glass 45, and an L-shaped outdoor side member 7212 arranged on the outdoor side X1 of the lower end of the glass 45.

[0140] The indoor side member 7211 is formed in an L-shape and has a front-facing extending portion 7211a that extends a predetermined distance toward the indoor side X2 from a position facing the visible surface of the indoor side X2 on the lower end side of the glass 45, and a downward extending portion 7211b that extends downward from the end of the front-facing extending portion 7211a on the indoor side X2. The front-facing extending portion 7211a extends in the front direction along the upper surface of the outer extending plate 7232b on the indoor side X2 of the fiber-reinforced core material 723. The downward extending portion 7211b extends vertically along the surface of the indoor side X2 of the indoor side frame portion 612 (described below) of the wheel support frame 61 of the door roller 6.

[0141] The exterior member 7212 is L-shaped and has a front-to-back extending portion 7212a that extends a predetermined distance toward the exterior side X1 from a position facing the visible surface of the exterior side X1 at the lower end of the glass 45, and a downward extending portion 7212b that extends downward from the end of the front-to-back extending portion 7212a on the exterior side X1. The front-to-back extending portion 7212a extends in the front direction along the upper surface of the outer extending plate 7232b on the exterior side X1 of the fiber-reinforced core material 723. The downward extending portion 7212b extends in the vertical direction along the surface of the exterior side X1 of the exterior frame portion 611 (described below) of the wheel support frame 61 of the door roller 6.

[0142] With the lower end of the glass 45 positioned in the U-shaped portion 726, adhesive 727 is arranged between the indoor-side X2 surface of the lower end of the glass 45 and the outdoor-side X1 end face of the front-to-back extending portion 7211a of the indoor-side member 7211 and the outdoor-side X1 end face of the L-shaped inward protruding portion 7232 on the indoor-side X2. Adhesive 727 is arranged between the outdoor-side X1 surface of the lower end of the glass 45 and the indoor-side X2 end face of the front-to-back extending portion 7212a of the outdoor-side member 7212 and the indoor-side X2 end face of the L-shaped inward protruding portion 7232 on the outdoor-side X1.

[0143] 9, the door roller 6 is disposed below the fiber reinforced core material 723 that is disposed below the lower end of the glass 45. The door roller 6 is disposed on the lower surface of the core material projection direction extension plate 7231 of the fiber reinforced core material 723.

[0144] The door roller 6 has a wheel support frame 61 (reinforcement portion) and a two-row wheel component 62 having two rows of wheel portions 621, 622 arranged in the front-to-rear direction, with multiple pairs of the two rows of wheel portions 621, 622 lined up in the left-to-right direction. The two rows of wheel portions 621, 622 are arranged at the lower end of the lower frame 42A (glass holding portion) that holds the lower end of the glass 45. The two rows of wheel portions 621, 622 are respectively arranged below a pair of outer extension plates 7232b formed on the outer sides (indoor side X2, outdoor side X1) of the core material front-to-rear direction extension plates 7231 of the fiber-reinforced core material 723. The fiber-reinforced core material 723 is arranged above the two rows of wheel portions 621, 622 of the door roller 6 that are arranged apart on the indoor side X2 and outdoor side X1, straddling the two rows of wheel portions 621, 622 in the front-to-rear direction. In this embodiment, as with the door roller 5 of the first embodiment, as shown in FIG. 1, the door roller 6 has four sets of wheel portions 621, 622 arranged in two rows in the left-right direction.

[0145] 9, the two rows of wheel units 621, 622 are arranged apart in the front direction on the outside side X1 and the inside side X2 of the room, sandwiching the lower end of the glass 45. Specifically, of the two rows of wheel units 621, 622, the wheel unit 621 on the outside side X1 is arranged away from the visible surface of the lower end of the glass 45 on the outside side X1 to the outside side X1, and the wheel unit 622 on the inside side X2 is arranged away from the visible surface of the lower end of the glass 45 on the inside side X2 to the inside side X2.

[0146] The two rows of wheel parts 621, 622 are arranged in the front direction at positions on the outside X1 and inside X2 of the front direction range in which the glass 45 is arranged, and in the vertical direction, a part of the upper side of the two rows of wheel parts 621, 622 is arranged in a position that overlaps the lower end of the glass 45 when viewed in the front direction. This makes it possible to make the front width (vertical width) of the lower frame 42A smaller than when the wheel parts are arranged at the lower end of the glass 45.

[0147] The two rows of wheel portions 621, 622 are rotatably arranged on the upper ends of the outdoor bottom frame rails 223A and 223B formed on the bottom frame 22A. The outdoor bottom frame rails 223A and indoor bottom frame rails 224A of the second embodiment are arranged at a greater distance in the front direction than the outdoor bottom frame rails 223 and indoor bottom frame rails 224 of the first embodiment.

[0148] The wheel support frame 61 is formed below the fiber-reinforced core material 723, extending in the front-to-rear direction. The wheel support frame 61 supports two rows of wheel sections 621, 622 and, by being located below the fiber-reinforced core material 723, reinforces the bottom frame 42A. The wheel support frame 61 is divided into two sections in the front-to-rear direction: an outdoor frame section 611 (outdoor-side reinforcement section) and an indoor frame section 612 (indoor-side reinforcement section). Both the outdoor frame section 611 and the indoor frame section 612 are formed from a metal material such as aluminum. A connecting member 613 (bridge member) is disposed between the outdoor frame section 611 and the indoor frame section 612. The connecting member 613 is formed from a thermally insulating material such as resin and connects the outdoor frame section 611 and the indoor frame section 612. The connecting member 613 is located below the fiber-reinforced core material 723.

[0149] The connecting member 613 blocks heat transfer from the outdoor side X1 to the indoor side X2 of the wheel support frame 61 of the door roller 6. A fiber reinforced core 723 (strength member) is arranged above the connecting member 613. Therefore, even if the connecting member 613 is made of resin, the connecting member 613 is provided below the fiber reinforced core 723, and therefore, by arranging the fiber reinforced core 723 above the connecting member 613, the strength of the wheel support frame 61 can be ensured.

[0150] The outdoor frame portion 611 has a frame body 611a that opens downward, and a hollow portion 611b that is located at the bottom of the frame body 611a on the indoor side X2. A wheel portion 621 on the outdoor side X1 is located inside the frame body 611a. A downward extension piece 614 that protrudes downward is formed at the end of the outdoor side X1 of the outdoor frame portion 611. An airtight material 2232 attached to an airtight material arrangement portion 2231 that protrudes toward the outdoor side X1 from a portion near the upper end of the outdoor bottom frame rail 223A of the bottom frame 22A in the vertical direction is in contact with the downward extension piece 614.

[0151] The indoor frame 612 has a frame body 612a that opens downward and a hollow portion 612b that is located below the outdoor side X1 of the frame body 612a. A wheel portion 622 on the indoor side X2 is located inside the frame body 612a.

[0152] The fitting 1 of the second embodiment has the following effects.

[0153] The building fixture 1 of this embodiment comprises glass 45, a door roller 6 provided at the lower end of the glass 45 in the viewing direction and having two rows of wheel portions 621, 622 spaced apart in the viewing direction, and a fiber-reinforced core material 723 as a strength member arranged between the door roller 6 and the glass 45 and spanning the two rows of wheel portions 621, 622.

[0154] Therefore, as in the first embodiment, the strength of the glass holder can be improved while maintaining thermal insulation performance, resulting in a slimmer frame and improved design. Furthermore, by providing a door roller 6 with two rows of wheels 621, 622 spaced apart in the forward direction, the sliding screen 4 can be stably moved by the two rows of wheels 521, 522, while the width of the lower frame 42A can be reduced, resulting in a slimmer frame 42A. Furthermore, by providing a fiber-reinforced core 723 as a strength member between the door roller 6 and the glass 45, the fiber-reinforced core 723 can support the weight of the glass 45 and ensure strength. This provides the strength to support heavy glass. While the present embodiment is configured to provide a fiber-reinforced core 723 as a strength member between the door roller 6 and the glass 45, the strength member provided between the door roller 6 and the glass 45 is not limited to the fiber-reinforced core 723. Any member capable of ensuring strength may be used as the strength member.

[0155] In this embodiment, the fiber reinforced core 723 is provided so as to cover the lower end of the glass 45 in the find direction, and has a U-shaped portion 726 that covers the end of the glass 45 in the find direction. This allows the fiber reinforced core 723 to be easily supported by the U-shaped portion 726 covering the lower end of the glass 45 in the find direction.

[0156] In this embodiment, the fiber-reinforced core 723 provided at the lower end of the glass 45 has a core-material front-side extension plate 7231 arranged along the lower end of the glass 45 and a pair of outer extension plates 7232b extending outward beyond the front surface of the glass 45 in the thickness direction of the glass 45. In this embodiment, the pair of outer extension plates 7232b extend from both ends of the open side of the U-shaped portion 726 toward the exterior side X1 and the interior side X2. As a result, even if the load of the glass 45 is applied to the lower end of the glass 45, the pair of outer extension plates 7232b can distribute and support the load of the glass 45 on the exterior side X1 and the interior side X2 in the thickness direction of the glass 45, thereby suppressing deformation of the lower end of the sliding shoji screen 4A.

[0157] In this embodiment, the sliding shoji screen 4A has a wheel support frame 61 arranged at the lower end thereof, which has an exterior frame portion 611, an interior frame portion 612, and a connecting member 613 arranged between the exterior frame portion 611 and the interior frame portion 612, and the connecting member 613 is provided below the fiber-reinforced core material 723. In this way, by connecting the exterior frame portion 611 and the interior frame portion 612 with the connecting member 613, it is possible to improve the heat insulating performance, and since the fiber-reinforced core material 723 is arranged above the connecting member 613, it is possible to ensure strength in the portion where the connecting member 613 is arranged.

[0158] In this embodiment, by configuring the fiber reinforced core material 723 with fiber reinforced plastic, it is possible to ensure high strength while also ensuring high heat insulation.

[0159] Next, the third embodiment will be described with respect to the joining stile 34B of the fixed shoji screen 3B and the joining stile 44B of the sliding shoji screen 4B. As shown in Fig. 10, the structure of the joining stile 34B of the fixed shoji screen 3B and the joining stile 44B of the sliding shoji screen 4B of the third embodiment is mainly different from the structure of the joining stile 34 of the fixed shoji screen 3 and the joining stile 44 of the sliding shoji screen 4 of the first embodiment shown in Fig. 7. In the third embodiment, the same components as in the first embodiment will be assigned the same reference numerals and their description will be omitted.

[0160] First, we will explain the joining vertical frame 34B of the FIX shoji screen 3B. As shown in Figure 10, the joining vertical frame 34B of the FIX shoji screen 3B has a wooden frame body 361 located at the end on the right side of the glass 35 (the other side in the viewing direction), a fiber-reinforced core material 363 located inside the frame body 361, and a hook part 364 located at the end of the joining vertical frame 34B on the room side X2.

[0161] The fiber reinforced core 363 is arranged to cover the right end in the left-right direction of the glass 35. The fiber reinforced core 363 has a core front-direction extension plate 3631 (first portion) extending in the front-direction, a pair of glass surface protrusions 3632 (second portion) arranged along the interior side X2 facing surface and the exterior side X1 facing surface of the right end in the left-right direction of the glass 35 midway in the front direction of the core front-direction extension plate 3631 and protruding to the left in the left-right direction, and a pair of exterior protrusions 3633 (second portion) protruding to the left in the left-right direction from the interior side X2 facing surface and the exterior side X1 facing surface of the core front-direction extension plate 3631, respectively.

[0162] In this embodiment, the pair of glass surface protrusions 3632 (second portions) and the pair of outer protrusions 3633 (second portions) are provided at positions at different distances in the front direction from the center position in the thickness direction of the glass 35. The pair of glass surface protrusions 3632 are arranged at the right end in the left-right direction of the glass 35 along the front surface on the indoor side X2 and the front surface on the outdoor side X1. The pair of outer protrusions 3633 are arranged inside the frame body 361 at positions away from the glass 35 on the indoor side X2 and the outdoor side X1 in the front direction.

[0163] The U-shaped U-shaped portion 366, which opens toward the left side in the left-right direction and is formed by the core material front-direction extension plate 3631 of the fiber-reinforced core material 363 and a pair of glass surface protrusions 3632, is arranged to cover the indoor side X2 surface, outdoor side X1 surface, and front side of the right end of the glass 35 in the left-right direction.

[0164] By positioning the right end of the glass 35 in the left-right direction so that it is covered by the U-shaped portion 366, the right end of the glass 35 in the left-right direction is positioned between a pair of glass surface protrusions 3632 in the left-right direction, with the end face (front face) extending in the front direction of the right end in the left-right direction being positioned on the left face in the left-right direction of the core material front direction extension plate 3631.

[0165] When the right end of the glass 35 in the left-right direction is positioned in the U-shaped portion 366, adhesive 367 is placed between the indoor side X2 surface of the right end of the glass 35 in the left-right direction and the outdoor side X1 surface of the glass surface protrusion 3632 on the indoor side X2, and adhesive 367 is placed between the outdoor side X1 surface of the right end of the glass 35 in the left-right direction and the indoor side X2 surface of the glass surface protrusion 3632 on the outdoor side X1.

[0166] The hook 364 is attached to the end of the interior side X2 of the joining vertical frame 34B and is formed in a U-shape that opens to the left in the left-right direction. The hook 364 is made of a metal material such as aluminum. When the sliding shoji screen 4B is in the closed position, the hook 364 is hooked onto the hook 464 of the joining vertical frame 44B of the sliding shoji screen 4B.

[0167] The wooden frame body 361 is arranged around the fiber-reinforced core material 363 so as to cover the fiber-reinforced core material 363. The wooden frame body 361 has an exterior interior member 3611 arranged on the exterior side X1 of the fiber-reinforced core material 363 between a core-material-inward-direction extension plate 3631, a glass surface protrusion 3632, and an outer protrusion 3633 of the fiber-reinforced core material 363; an enclosing member 3612 arranged to surround a right portion of the fiber-reinforced core material 363 in the left-right direction and an end portion on the exterior side X1 of the fiber-reinforced core material 363; an interior interior member 3613 arranged on the interior side X2 of the fiber-reinforced core material 363 between the core-material-inward-direction extension plate 3631, a glass surface protrusion 3632, and an outer protrusion 3633 of the fiber-reinforced core material 363; and an interior extension portion 3614 arranged on the left side in the left-right direction at the end of the fiber-reinforced core material 363 on the interior side X2 of the fiber-reinforced core material 363. The outdoor interior member 3611, the surrounding member 3612, the indoor interior member 3613, and the indoor extension portion 3614 are made of wood (wood). The outdoor interior member 3611, the surrounding member 3612, the indoor interior member 3613, and the indoor extension portion 3614 may all be constructed separately, or all may be constructed as a single unit, or the outdoor interior member 3611, the surrounding member 3612, the indoor interior member 3613, and the indoor extension portion 3614 may be constructed by dividing them in the middle.

[0168] The enclosing member 3612 has a front-direction extending portion 3612a extending in the front-direction, a front-direction inward extending portion 3612b extending from the outside-side X1 end of the front-direction extending portion 3612a to the left in the left-right direction, and an indoor-side extending portion 3612c extending from the left-side end of the front-direction inward extending portion 3612b to the inside X2.

[0169] The front-facing extending portion 3612a extends in the front-facing direction along the right surface of the core front-facing extending plate 3631 and the right surface of the hook portion 364. The front-facing inward extending portion 3612b extends in the front-facing direction along the outdoor side X1 surface of the fiber reinforced core 363 so as to cover the outdoor side X1 surface of the fiber reinforced core 363.

[0170] The indoor extension portion 3612c extends in the forward direction along the left-right surface at the end portion on the outdoor side X1 of the fiber-reinforced core material 363 so as to cover the left-right surface at the end portion on the outdoor side X1 of the fiber-reinforced core material 363 and the outdoor internal member 3611.

[0171] The indoor extension portion 3614 extends in the forward direction along the left side surface in the left-right direction at the end portion on the indoor side X2 of the fiber-reinforced core material 363 so as to cover the left side surface in the left-right direction and the indoor side internal member 3613 at the end portion on the indoor side X2 of the fiber-reinforced core material 363.

[0172] Next, we will explain the joining vertical frame 44B of the sliding shoji screen 4B. As shown in Figure 10, the joining vertical frame 44B has a wooden frame body 461 located at the end on the left side of the glass 45 (one side in the viewing direction), a fiber-reinforced core material 463 located inside the frame body 461, and a hook part 464 located at the end of the joining vertical frame 44B on the outside side X1.

[0173] The joining vertical frame 44B is formed by rotating the joining vertical frame 34B of the FIX shoji screen 3B shown in FIG. 10 by 180 degrees, and an airtight material 464a is placed in the hook portion 464 (airtight material placement portion). Therefore, in the description of the joining vertical frame 44B, parts similar to those of the joining vertical frame 34B of the FIX shoji screen 3B described above will be assigned corresponding reference numerals and will not be described again. The hook portion 464 is made of metal, and is formed of a metal material such as aluminum. The hook portion 464 may also be made of resin.

[0174] An airtight material 464a is attached to the exterior X1 surface of the hook portion 464 of the joining vertical frame 44B, which is located on the interior X2 side. When the sliding shoji screen 4A is in the closed position, the airtight material 464a abuts against the interior X2 surface of the hook portion 364 of the joining vertical frame 34B of the fixed shoji screen 3B, which is located on the interior X2 side.

[0175] When the sliding shoji screen 4B is in the closed position, the hook portion 464 is positioned so as to be hooked onto the hook portion 364 of the joining vertical frame 34B of the fixed shoji screen 3B. As a result, when the sliding shoji screen 4B moves from the open position to the closed position, the sliding shoji screen 4B is restricted from moving to the right in the left-right direction from the position where the hook portion 464 is hooked onto the hook portion 364 of the joining vertical frame 34B of the fixed shoji screen 3B. This makes it possible to prevent the sliding shoji screen 4B from colliding with the frame-side vertical frame 24 (see FIG. 2) which is positioned on the right side in the left-right direction of the frame body 2.

[0176] The joining vertical frame 34B of the fixed shoji screen 3B and the joining vertical frame 44B of the sliding shoji screen 4B of the third embodiment of the building fixture 1 not only achieve the same effects as the joining vertical frame 34 of the fixed shoji screen 3 and the joining vertical frame 44 of the sliding shoji screen 4 of the first embodiment of the building fixture 1, but also achieve the following effects.

[0177] In this embodiment, the pair of glass surface protrusions 3632 (second portions) and the pair of outer protrusions 3633 (second portions) are provided at positions at different distances in the front direction from the center position in the thickness direction of the glass 35. The pair of glass surface protrusions 3632 are arranged at the right end of the glass 35 in the front direction along the front face on the interior side X2 and the front face on the exterior side X1. Therefore, the pair of glass surface protrusions 3632 can support the right end of the glass 35 in the front direction while being aligned with the front face on the interior side X2 and the front face on the exterior side X1 at the left and right end of the glass 35. The pair of outer protrusions 3633 are arranged inside the frame body 361 at positions spaced apart from the glass 35 on the interior side X2 and the exterior side X1 in the front direction. Therefore, strength can be improved at positions spaced apart from the glass 35 on the interior side X2 and the exterior side X1 in the front direction, and wind pressure resistance can be improved.

[0178] Next, we will explain the joining stile 34C of the fixed shoji screen 3C and the joining stile 44C of the sliding shoji screen 4C of the fourth embodiment. As shown in Figure 11, the structure of the joining stile 34C of the fixed shoji screen 3C and the joining stile 44C of the sliding shoji screen 4C of the fourth embodiment is mainly different from the structure of the joining stile 34 of the fixed shoji screen 3 and the joining stile 44 of the sliding shoji screen 4 of the first embodiment shown in Figure 7. In the fourth embodiment, for configurations similar to those in the first embodiment, the same members are assigned the same reference numerals and explanations are omitted.

[0179] First, we will explain the joining vertical frame 34C of the FIX shoji screen 3C. As shown in Figure 11, the joining vertical frame 34C of the FIX shoji screen 3C has a metal frame body 371 located at the end on the right side of the glass 35 in the left-right direction (the other side in the viewing direction), and a fiber-reinforced core material 373 located inside the frame body 371. The fourth embodiment is different from the first embodiment mainly in that the frame body 341 of the first embodiment shown in Figure 7 is made of wood, while the frame body 371 of the fourth embodiment is made of metal.

[0180] The configuration of the fiber reinforced core material 373 is similar to the configuration of the fiber reinforced core material 343 of the first embodiment shown in FIG. 7, so corresponding reference numerals are used and the description will be omitted.

[0181] The metal frame body 371 is arranged around the fiber-reinforced core material 373 so as to cover the fiber-reinforced core material 373. The metal frame body 371 has an enclosing member 3711 arranged to surround the right side portion of the fiber-reinforced core material 373 in the left-right direction and the end portion on the outside side X1, and an indoor-facing-direction inner side member 3712 arranged on the left side in the left-right direction at the end portion on the indoor side X2 of the fiber-reinforced core material 373. The enclosing member 3711 and the indoor-facing-direction inner side member 3712 are made of metal members such as aluminum.

[0182] The enclosing member 3711 has a front-direction extending portion 3711a extending in the front-direction, a front-direction inward extending portion 3711b extending from the outside-side X1 end of the front-direction extending portion 3711a to the left in the left-right direction, and an indoor-side extending portion 3711c extending from the left-side end of the front-direction inward extending portion 3711b to the inside-side X2.

[0183] The projection direction extending portion 3711a extends in the projection direction along the right side surfaces of the U-shaped hook portion 3735 of the fiber reinforced core material 373, the core material projection direction extending plate 3731 of the fiber reinforced core material 373, and the outward protruding plate 3734, so as to cover the right side surface in the left-right direction of the U-shaped hook portion 3735 of the fiber reinforced core material 373, the right side surface in the left-right direction of the core material projection direction extending plate 3731 of the fiber reinforced core material 373, and the right side surface in the left-right direction of the outward protruding plate 3734. The inward extending portion 3711b in the facing direction extends in the facing direction along the outdoor side X1 surface of the outward protruding plate 3734 of the fiber reinforced core material 373 and the outdoor side X1 surface of the inner extending plate 3733a of the L-shaped inward protruding portion 3733, so as to cover the outdoor side X1 surface of the outward protruding plate 3734 of the fiber reinforced core material 373 and the outdoor side X1 surface of the inner extending plate 3733a of the L-shaped inward protruding portion 3733.

[0184] The indoor extension portion 3711c extends along the left side surface of the protruding plate 3733b of the L-shaped inward protruding portion 3733 of the fiber reinforced core material 373 so as to cover the left side surface of the protruding plate 3733b of the L-shaped inward protruding portion 3733 of the fiber reinforced core material 373.

[0185] Next, we will explain the joining vertical frame 44C of the sliding shoji screen 4C. As shown in Figure 11, the joining vertical frame 44C of the sliding shoji screen 4C has a metal frame body 471 located at the end on the left side of the glass 45 (one side in the viewing direction) in the left-right direction, and a fiber-reinforced core material 473 located inside the frame body 471.

[0186] The joining stile 44C is formed by rotating the joining stile 34C of the FIX shoji screen 3C shown in FIG. 11 by 180 degrees, and an airtight material 4712a is placed in the interior facing member 4712 (airtight material placement portion) on the interior side facing direction. The interior facing member 4712 is made of metal, and is formed of a metal material such as aluminum. The interior facing member 4712 may also be made of resin. Therefore, in describing the joining stile 44C, parts with the same configuration as the joining stile 34C of the FIX shoji screen 3C shown in FIG. 11 are designated by corresponding reference numerals, and description thereof will be omitted.

[0187] An airtight material 4712a is attached to the exterior X1 surface of the portion of the interior facing member 4712 located on the interior X2 side. When the sliding shoji screen 4C is in the closed position, the airtight material 4712a abuts against the interior X2 surface of the U-shaped hook portion 3735 of the joining vertical frame 34C of the fixed shoji screen 3C.

[0188] The vertical joining frame 34C of the FIX shoji screen 3C and the vertical joining frame 44C of the sliding shoji screen 4C of the fitting 1 of the fourth embodiment have frame bodies 371, 471 made of metal, whereas the vertical joining frame 34 of the FIX shoji screen 3 and the vertical joining frame 44 of the sliding shoji screen 4 of the fitting 1 of the first embodiment have frame bodies made of wood. The vertical joining frame 34C of the FIX shoji screen 3C and the vertical joining frame 44C of the sliding shoji screen 4C of the fitting 1 of the fourth embodiment can achieve the same effects as the vertical joining frame 34 of the FIX shoji screen 3 and the vertical joining frame 44 of the sliding shoji screen 4 of the fitting 1 of the first embodiment, except for the effect of using wood for the frame bodies in the first embodiment.

[0189] Next, the joining vertical frame 34D of the fixed shoji screen 3D and the joining vertical frame 44D of the sliding shoji screen 4D of the fifth embodiment will be described. As shown in Figure 12, the structure of the joining vertical frame 34D of the fixed shoji screen 3D and the joining vertical frame 44D of the sliding shoji screen 4D of the fifth embodiment is such that, while the frame main bodies 371, 471 in the structure of the joining vertical frame 34C of the fixed shoji screen 3C and the joining vertical frame 44C of the sliding shoji screen 4C of the fourth embodiment shown in Figure 11 are made of metal members, the frame main bodies 380, 480 are made of wooden external members 381, 481 that are exposed to the outside and metal attachment members 382, ​​482 that are placed on the inside of the external members 381, 481, so that the wooden external members 381, 481 can be attached to the outside of the fiber-reinforced core material 383, 483 via the metal attachment members 382, ​​482.

[0190] First, we will explain the joining vertical frame 34D of the FIX shoji screen 3D. As shown in Figure 12, the joining vertical frame 34D of the FIX shoji screen 3D has a frame body 380 located at the end on the right side of the glass 35 in the left-right direction (the other side in the viewing direction), and a fiber-reinforced core material 383 located inside the frame body 380. The frame body 380 has a wooden external member 381 located on the outside, and a metal attachment member 382 located inside the external member 381.

[0191] The configuration of fiber reinforced core 383 is similar to the configurations of fiber reinforced core 343 shown in FIG. 7 and fiber reinforced core 373 shown in FIG. 11, so corresponding reference numerals are used and description thereof will be omitted.

[0192] The metal attachment member 382 is arranged around the fiber-reinforced core material 383 so as to cover the fiber-reinforced core material 383. The metal attachment member 382 has an enclosing member 3821 arranged to surround the right side of the fiber-reinforced core material 383 and the end portion on the outside X1 side, and an indoor-facing-side inner member 3822 arranged on the left side of the end portion on the indoor X2 side of the fiber-reinforced core material 383. The enclosing member 3821 and the indoor-facing-side inner member 3822 are made of metal members such as aluminum. The metal attachment member 382 has a basic configuration similar to that of the metal frame body 371 shown in FIG. 11 , so corresponding reference numerals are used and a description thereof is omitted.

[0193] The wooden external member 381 is disposed outside the metal attachment member 382 so as to cover the metal attachment member 382. The wooden external member 381 has an enclosing external member 3811 that covers the outside of the enclosing member 3821 of the metal attachment member 382, ​​and an inner external member 3812 that covers the left side surface in the left-right direction of the inner side member 3822 of the metal attachment member 382 in the room interior facing direction. In this way, the fiber reinforced core material 383 is attached to the wooden external member 381 via the metal attachment member 382.

[0194] When attaching the stile body 380 to the fiber-reinforced core material 383, the wooden external member 381 can be easily attached to the fiber-reinforced core material 383 via the metal attachment member 382 by attaching the wooden external member 381 to the fiber-reinforced core material 383 with the metal attachment member 382 attached inside the wooden external member 381. This makes it easier to attach the stile body 380 to the fiber-reinforced core material 383 than if the stile body were made of wood only.

[0195] Next, we will explain the joining vertical frame 44D of the sliding shoji screen 4D. As shown in Figure 12, the joining vertical frame 44D has a frame body 480 located at the end on the left side of the glass 35 (one side in the viewing direction) in the left-right direction, and a fiber-reinforced core material 483 located inside the frame body 480. The frame body 480 has a wooden external member 481 located on the outside, and a metal attachment member 482 located inside the external member.

[0196] The joining stile 44D is the joining stile 34D of the fixed shoji screen 3D shown in FIG. 12, rotated 180°, and an airtight material 4822a is placed in the interior facing side member 4822 (airtight material placement portion). In the explanation of the joining stile 44D, the same components as those of the joining stile 34D of the fixed shoji screen 3D described above are assigned corresponding reference numerals and explanations are omitted. The interior facing side member 4822 is made of metal, and is formed from a metal material such as aluminum. The interior facing side member 4822 may also be made of resin.

[0197] An airtight material 4822a is attached to the exterior X1 surface of the interior facing member 4822. When the sliding shoji screen 4 is in the closed position, the airtight material 4822a abuts against the interior X2 surface of the U-shaped hook portion 3835 of the joining vertical frame 34 of the fixed shoji screen 3.

[0198] The joining vertical frame 34D of the fixed shoji screen 3D and the joining vertical frame 44D of the sliding shoji screen 4D of the fifth embodiment of the building fixture 1 not only achieve the same effects as the joining vertical frame 34 of the fixed shoji screen 3 and the joining vertical frame 44 of the sliding shoji screen 4 of the first embodiment of the building fixture 1, but also achieve the following effects.

[0199] In this embodiment, the wooden external member 381 can be easily attached to the fiber-reinforced core material 383 via the metal attachment member 382. This makes it easier to attach the frame body 380 to the fiber-reinforced core material 383 than if the frame body were made of wood alone. This results in good workability for the joining vertical frame 34D of the fixed shoji screen 3D and the joining vertical frame 44D of the sliding shoji screen 4D.

[0200] Next, the sixth embodiment will be described with respect to the joining stile 34E of the fixed shoji screen 3E and the joining stile 44E of the sliding shoji screen 4E. As shown in FIG. 13, the structure of the joining stile 34E of the fixed shoji screen 3E and the joining stile 44E of the sliding shoji screen 4E in the sixth embodiment is mainly different from the structure of the joining stile 34 of the fixed shoji screen 3 and the joining stile 44 of the sliding shoji screen 4 in the first embodiment shown in FIG. 7. In the sixth embodiment, the same components as in the first embodiment are denoted by the same reference numerals, and their description will be omitted. In the sixth embodiment, the joining stile 34E of the fixed shoji screen 3E and the joining stile 44E of the sliding shoji screen 4E have their exposed portions on the indoor side X2 made of wood, and their exposed portions on the outdoor side X1 made of metal.

[0201] As shown in Fig. 13, the joining vertical frame 34E of the FIX shoji screen 3E has a frame body 391 arranged at the end on the right side (the other side in the viewing direction) of the glass 35 in the left-right direction, and a fiber-reinforced core material 393 arranged inside the frame body 391. In the sixth embodiment, while the surrounding member 3411 of the frame body 341 of the FIX shoji screen 3 of the first embodiment shown in Fig. 7 is made of wood, as shown in Fig. 13, the surrounding member 3911 of the frame body 391 is made of metal.

[0202] 13, the joining vertical frame 44E of the sliding shoji screen 4E has a frame body 491 arranged at the end on the left side (one side in the view direction) of the glass 45 in the left-right direction, and a fiber-reinforced core material 493 arranged inside the frame body 491. In the sixth embodiment, whereas the wooden frame body 441 has an inner member 4412 in the view direction of the interior of the room arranged on the right side in the left-right direction of the end on the outside X1 of the joining vertical frame 44 of the sliding shoji screen 4 of the first embodiment shown in FIG. 7, as shown in FIG. 13, the width in the left-right direction of the metal airtight material arrangement frame 4913 (airtight material arrangement portion) attached to the right side in the left-right direction of the end on the outside X1 of the joining vertical frame 44E is made larger, and the metal airtight material arrangement frame 4913 is attached to the right side in the left-right direction at the end on the outside X1 of the joining vertical frame 44E. The metal airtight material arrangement frame 4913 is exposed to the outside of the room X1. The airtight material arrangement frame 4913 is made of metal, and is formed of a metal material such as aluminum. The airtight material arrangement frame 4913 may also be made of resin.

[0203] The vertical joining frame 34E of the fixed shoji screen 3E and the vertical joining frame 44E of the sliding shoji screen 4E of the sixth embodiment of the building fixture 1 not only achieve the same effects as the vertical joining frame 34 of the fixed shoji screen 3 and the vertical joining frame 44 of the sliding shoji screen 4 of the first embodiment of the building fixture 1, but also achieve the following effects.

[0204] In this embodiment, the part exposed to the indoor side X2 is made of wood, giving the indoor side X2 a sense of real wood, while the part exposed to the outdoor side X1 is made of metal, so deterioration due to exposure to sunlight, etc., can be suppressed on the outdoor side X1.

[0205] Next, referring to Figures 14 and 15, the joining vertical frame 34F of the fixed shoji screen 3F and the joining vertical frame 44F of the sliding shoji screen 4F of the seventh embodiment, as well as the bottom frame 42F of the sliding shoji screen 4F of the seventh embodiment will be described.

[0206] As shown in Figure 14, the structure of the joining vertical frame 34F of the fixed shoji screen 3F and the joining vertical frame 44F of the sliding shoji screen 4F in the seventh embodiment is mainly different from the structure of the joining vertical frame 34 of the fixed shoji screen 3 and the joining vertical frame 44 of the sliding shoji screen 4 shown in Figure 7 of the first embodiment. Also, as shown in Figure 15, the bottom frame 42F of the sliding shoji screen 4F in the seventh embodiment is mainly different from the structure of the bottom frame 42 of the sliding shoji screen 4 shown in Figure 8 of the first embodiment. In the seventh embodiment, for configurations similar to those in the first embodiment, the same members are assigned corresponding symbols and descriptions thereof are omitted.

[0207] First, of the joining vertical frame 34F of the fixed shoji screen 3F and the joining vertical frame 44F of the sliding shoji screen 4F in the seventh embodiment, the joining vertical frame 34F of the fixed shoji screen 3F will be described.

[0208] As shown in Figure 14, the joining vertical frame 34F of the FIX shoji screen 3F has a wooden frame body 351 arranged at the end on the right side (the other side in the viewing direction) of the glass 35, a fiber-reinforced core material 353 arranged inside the frame body 351, and a pair of resin angles 354.

[0209] The fiber reinforced core 353 is arranged to cover the right end in the left-right direction of the glass 35. The fiber reinforced core 353 has a core material front-direction extension plate 3531 (first portion) extending in the front direction, a pair of two inward protruding portions 3532, 3533 (second portions) provided on the indoor side X2 and the outdoor side X1 of the core material front-direction extension plate 3531 respectively and protruding to the left in the left-right direction, and a U-shaped hook portion 3534 arranged on the indoor side X2 midway in the front direction of the core material front-direction extension plate 3531.

[0210] The pair of two inward protrusions 3532, 3533 are provided as a set on the indoor side X2 and the outdoor side X1 of the core material forward direction extension plate 3531. The two inward protrusions 3532, 3533 are composed of a first inward protrusion 3532 that protrudes to the left in the left-right direction on the side closer to the glass 35, and a second inward protrusion 3533 that protrudes to the left in the left-right direction from the end of the indoor side X2 or the outdoor side X1 of the core material forward direction extension plate 3531 on the side farther from the glass 35.

[0211] The first inward protrusion 3532 and the second inward protrusion 3533 extend in the left-right direction and are arranged parallel to each other in the projection direction with a gap of a predetermined width therebetween. The first inward protrusion 3532, the second inward protrusion 3533, and the core projection direction extending plate 3531 are arranged in a U-shape with a gap that opens toward the left in the left-right direction, and a mounting plate 3541 of the resin angle bracket 354, which will be described later, is inserted between the first inward protrusion 3532 and the second inward protrusion 3533 by press fitting.

[0212] The U-shaped U-section 356, which is open to the left in the left-right direction and is formed by the core material projection extension plate 3531 of the fiber-reinforced core material 353, the first inward protrusion 3532 on the indoor side X2, and the first inward protrusion 3532 on the outdoor side X1, is positioned to cover the right end of the glass 35 in the left-right direction, and covers the indoor side X2 surface, the outdoor side X1 surface, and the projection surface of the right end in the left-right direction of the glass 35.

[0213] The U-shaped hook portion 3534 is formed in a U-shape that opens to the left in the left-right direction near the end of the indoor side X2 of the joining vertical frame 34F. When the sliding shoji screen 4F is in the closed position, the U-shaped hook portion 3534 is hooked onto a U-shaped hook portion 4534 (described later) of the joining vertical frame 44F of the sliding shoji screen 4F.

[0214] With the right end of the glass 35 covered by the U-shaped portion 356, a sealant 357 is disposed between the interior X2 and exterior X1 facing surfaces of the right end of the glass 35 and the first inward protrusion 3532 on the interior X2 side and the first inward protrusion 3532 on the exterior X1 side of the fiber-reinforced core 353 at the open side of the U-shaped portion 356. A backup material 358 is disposed between the sealant 357 and the left side of the core-reinforced-core-front-direction extension plate 3531 of the fiber-reinforced core 353 at the closed side of the U-shaped portion 356. The sealant 357 may be a glazing channel.

[0215] On the indoor side X2 and the outdoor side X1 of the glass 35, a mounting plate 3541 of the resin angle 354 is inserted between the first inward protrusion 3532 and the second inward protrusion 3533 and attached by press fitting. The resin angle 354 has the mounting plate 3541 that is disposed in the gap between the first inward protrusion 3532 and the second inward protrusion 3533 and extends in the left-right direction, and a cover plate 3542 that is connected to the left end of the mounting plate 3541 in the left-right direction and extends in the forward direction.

[0216] The covering plate 3542 is formed to extend in the front direction along the left end face in the left-right direction of the sealing material 357 and the left end faces in the left-right direction of the first inward protrusion 3532 and the second inward protrusion 3533, and extends in the front direction so as to cover the portion sealed by the sealing material 357. An inner cover part 3513 (described later) of the wooden frame main body 351 is attached to the left face in the left-right direction of the covering plate 3542.

[0217] The wooden frame body 351 is arranged around the fiber-reinforced core material 353 so as to cover the fiber-reinforced core material 353. The wooden frame body 351 has an enclosing member 3511 arranged to surround the right side portion of the fiber-reinforced core material 353 in the left-right direction and the portion on the outside X1 end side, an indoor-facing-direction inner side member 3512 arranged on the indoor-facing-direction end side of the core-facing-direction extension plate 3531 of the fiber-reinforced core material 353, and a pair of inner cover parts 3513 arranged along the left-facing-direction surfaces of the pair of resin angles 354. The enclosing member 3511, the indoor-facing-direction inner side member 3512, and the pair of inner cover parts 3513 are made of wooden members (lumber).

[0218] The enclosing member 3511 has a front-direction extending portion 3511a extending in the front direction, and a front-direction inward extending portion 3511b extending from the end of the front-direction extending portion 3511a on the outside side X1 to the left in the left-right direction.

[0219] The front-facing extending portion 3511a extends in the front-facing direction along the right-side surface of the U-shaped hook portion 3534 of the fiber reinforced core 353 and the core front-facing extending plate 3531 so as to cover the right-side surface of the U-shaped hook portion 3534 of the fiber reinforced core 353 and the right-side surface of the core front-facing extending plate 3531. The front-facing inward extending portion 3511b extends in the front-facing direction along the outside X1 surface of the second inward protruding portion 3533 of the outdoor side X1 of the fiber reinforced core 353 so as to cover the outside X1 surface of the second inward protruding portion 3533 of the outdoor side X1 of the fiber reinforced core 353.

[0220] The indoor side facing direction inner side member 3512 is arranged along the indoor side X2 surface of the second inward protruding portion 3533 on the indoor side X2 of the fiber reinforced core material 353.

[0221] The pair of inner cover portions 3513 are arranged on the left side in the left-right direction of the sealant 357 to hide the sealant 357 that is arranged on the outside side X1 and inside side X2 of the right end portion in the left-right direction of the glass 35. The pair of inner cover portions 3513 are attached to the first inward protruding portion 3532 and the second inward protruding portion 3533 of the fiber reinforced core material 353 via resin angles 354, respectively.

[0222] The pair of inner cover parts 3513 extend forward along the left side surface in the left-right direction of the cover plate 3542 of the resin angle part 354 attached to the left side in the left-right direction of the first inward protrusion part 3532 and the second inward protrusion part 3533 of the fiber reinforced core material 353, at the indoor side X2 and the outdoor side X1 of the right end part in the left-right direction of the glass 35. The pair of inner cover parts 3513 are attached to the left side surface in the left-right direction of the cover plate 3542 of the resin angle part 354.

[0223] After applying the sealant 357 to the outside surface X1 and inside surface X2 of the right end of the glass 35 in the left-right direction, when the wooden inner cover part 3513 is positioned on the left side of the sealant 357 in the left-right direction via the resin angle 354, the inner cover part 3513 is attached in advance to the left side surface in the left-right direction of the covering plate 3542 of the resin angle 354, and then the mounting plate 3541 of the resin angle 354 is inserted and attached by pressing between the first inward protrusion 3532 and the second inward protrusion 3533 of the fiber reinforced core material 353. Furthermore, when removing the wooden inner cover part 3513 arranged on the left side of the sealing material 357, the mounting plate 3541 of the resin angle part 354 is removed from the first inward protrusion 3532 and the second inward protrusion 3533 of the fiber reinforced core material 353 with the inner cover part 3513 attached to the left side surface of the covering plate 3542 of the resin angle part 354. In this way, the inner cover part 3513 can be attached to the fiber reinforced core material 353 later or removed from the fiber reinforced core material 353 while attached to the resin angle part 354.

[0224] As described above, by attaching the wooden inner cover part 3513 to the left side of the sealant 357 in the left-right direction via the resin angle 354, the wooden inner cover part 3513 can hide the sealant 357 arranged on the outside side X1 and inside side X2 of the right end of the glass 35 in the left-right direction, thereby improving the design.

[0225] Furthermore, since the wooden inner cover part 3513 is attached to the fiber reinforced core material 353 via the resin angle 354, the wooden inner cover part 3513 can be attached to the fiber reinforced core material 353 via the resin angle 354 while suppressing warping of the wooden inner cover part 3513 compared to attaching the wooden inner cover part 3513 directly to the fiber reinforced core material 353.

[0226] In addition, the insulation performance can be improved by covering the sealing material 357 placed on the outside X1 and inside X2 of the right end of the glass 35 in the left-right direction with a resin angle 354 made of resin with excellent insulation properties and an inner cover part 3513 made of wood with excellent insulation properties.

[0227] In this way, after applying the sealing material 357 to the outside surface X1 and the inside surface X2 of the right end of the glass 35 in the left-right direction, the wooden inner cover part 3513 can be attached to the fiber reinforced core material 353 via the resin angle 354 made of resin, thereby creating an attachment structure for the wooden inner cover part 3513 that combines improved design, suppression of wood warping, and improved insulation.

[0228] Next, of the joining vertical frame 34F of the fixed shoji screen 3F and the joining vertical frame 44F of the sliding shoji screen 4F in the seventh embodiment, the joining vertical frame 44F of the sliding shoji screen 4F will be described.

[0229] As shown in Figure 14, the joining vertical frame 44F has a wooden frame body 451 arranged at the end on the left side of the glass 45 in the left-right direction (one side in the viewing direction), a fiber-reinforced core material 453 arranged inside the frame body 451, and a pair of resin angles 454.

[0230] The joining vertical frame 44F is configured by rotating the joining vertical frame 34F of the FIX shoji screen 3F shown in Figure 14 described above by 180 degrees, and providing an airtight material arrangement section 4536 integrated with the fiber-reinforced core material 453 in the part where the inner side member 3512 on the indoor side facing direction was located, and extending the inner cover section 4513 on the outdoor side X1 to the outdoor side X1, and placing a spacer 4514 between the airtight material arrangement section 4536 and the inner cover section 4513 on the outdoor side X1. The configuration of the pair of inner cover sections 4513 of the wooden frame body 451 and the pair of resin angles 454 is similar to the configuration of the pair of inner cover sections 3513 and resin angles 354 of the wooden frame body 351 of the joining vertical frame 34 of the FIX shoji screen 3F. Regarding the explanation of the joining vertical frame 44F, the same configuration as the joining vertical frame 34F of the fixed shoji screen 3F shown in Figure 14 above will be assigned the corresponding symbols and the explanation will be omitted.

[0231] The fiber reinforced core 453 of the joining vertical frame 44F is formed with a protruding plate 4535 that protrudes from the right end in the left-right direction of the inward protruding portion 4533 on the outside side X1 toward the outside side X1 at the inward protruding portion 4533 on the outside side X1. The end on the outside side X1 of the core material projection direction extending plate 4531 of the fiber reinforced core 453, the inward protruding portion 4533 on the outside side X1, and the protruding plate 4535 form a U-shaped airtight material arrangement portion 4536 that is recessed toward the inside side X2 and opens toward the outside side X1.

[0232] An airtight material 4537 is attached to a recess that opens to the outside side X1 of the airtight material arrangement portion 4536. The airtight material 4537 has a horizontal plate portion 4537a extending in the left-right direction, an airtight pressing portion 4537b that protrudes from the outside side X1 surface of the horizontal plate portion 4537a toward the outside side X1, a central protrusion 4537c that protrudes from the left-right center of the indoor side X2 surface of the horizontal plate portion 4537a toward the indoor side X2, and a pair of fitting protrusions 4537d that protrude from both left-right end sides of the indoor side X2 surface of the horizontal plate portion 4537a toward the indoor side X2.

[0233] The airtight material 4537 is fixed by being bonded with adhesive 4538 to the outside-room X1 surface of the bottom of the recess of the airtight material arrangement portion 4536, with the base end of the airtight material 4537 being inserted into the recess of the airtight material arrangement portion 4536, with the pair of fitting protrusions 4537d fitted into the side walls of both left and right ends of the bottom of the recess of the airtight material arrangement portion 4536. The adhesive 4538 is filled between the central protrusion 4537c and each of the pair of fitting protrusions 4537d arranged on both left and right sides of the central protrusion 4537c on the base end side of the airtight material 4537, and bonds and fixes the base end of the airtight material 4537 to the bottom of the recess of the airtight material arrangement portion 4536.

[0234] In this embodiment, fiber reinforced core material 453 is made of fiber reinforced plastic, and it is difficult to form it into a complex shape, such as a C-hole shape having a pair of inward protrusions protruding inward from both ends. Therefore, in this embodiment, airtight material arranging portion 4536 is formed by simply providing a recess in fiber reinforced core material 453, and the base end side of airtight material 4537 is bonded and fixed to the recess in airtight material arranging portion 4536 with adhesive 4538.

[0235] When the sliding shoji screen 4F is in the closed position, the airtight pressing portion 4537b of the airtight material 4537 abuts against the indoor side X2 surface of the U-shaped hook portion 3534 of the joining vertical frame 34F of the fixed shoji screen 3F.

[0236] In this embodiment, the airtight material arranging portion 4536 is provided integrally with the fiber-reinforced core material 453. This allows the airtight material 4537 to be directly attached to the fiber-reinforced core material 453 without a separate component, compared to the previously described embodiments in which a separate airtight material arranging portion made of metal such as aluminum is provided in the fiber-reinforced core material (e.g., the hook 464 in FIG. 10 , the inner member 4712 facing the room side in FIG. 11 , the inner member 4822 facing the room side in FIG. 12 , and the airtight material arranging frame 4913 in FIG. 13 ). This reduces the number of components. Furthermore, in this embodiment, the airtight material arranging portion 4536 can be provided integrally with the fiber-reinforced core material 453 without a separate airtight material arranging portion made of metal such as aluminum, thereby improving thermal insulation compared to the case in which a separate airtight material arranging portion made of metal such as aluminum is provided.

[0237] Next, we will explain the bottom frame 42F of the sliding shoji screen 4F of the seventh embodiment. As shown in Fig. 15, the bottom frame 42F has a wooden frame body 821 arranged at the lower end of the viewing direction of the glass 45, a fiber-reinforced core material 823 (strength member) arranged inside the frame body 821, a pair of resin angles 824, and a door roller 9 arranged at the lower end of the bottom frame 42F.

[0238] The fiber reinforced core 823 is arranged to cover the lower end of the glass 45. The fiber reinforced core 823 has a core front-direction extension plate 8231 (first portion) extending in the front-direction, a pair of two inward protruding portions 8232, 8233 (second portions) provided on the indoor side X2 and the outdoor side X1 of the core front-direction extension plate 8231, respectively, and protruding upward in the vertical direction (inward in the sight direction), and a pair of outward extending portions 8234 (second portions) extending downward in the vertical direction (outward in the sight direction) from the end portion on the indoor side X2 and the end portion on the outdoor side X1 in the front direction of the core front-direction extension plate 8231.

[0239] The pair of two inward protrusions 8232, 8233 are provided as a set on the indoor side X2 and the outdoor side X1 of the core material forward direction extension plate 8231. The two inward protrusions 8232, 8233 are composed of a first inward protrusion 8232 that protrudes upward on the side closer to the glass 45, and a second inward protrusion 8233 that protrudes upward from the end of the indoor side X2 or the outdoor side X1 of the core material forward direction extension plate 8231 on the side farther from the glass 45.

[0240] The first inward protrusion 8232 and the second inward protrusion 8233 extend in the vertical direction and are arranged parallel to each other in the projection direction with a gap of a predetermined width therebetween. The first inward protrusion 8232, the second inward protrusion 8233, and the core material projection direction extending plate 8231 are arranged in a U-shape with a gap that opens upward in the vertical direction, and a mounting plate 8241 of a resin angle bracket 824 (described later) is inserted between the first inward protrusion 8232 and the second inward protrusion 8233 by press fitting.

[0241] The U-shaped U-section 826, which is open upward in the vertical direction and is formed by the core material projection direction extension plate 8231 of the fiber reinforced core material 823, the first inward protrusion 8232 on the indoor side X2, and the first inward protrusion 8232 on the outdoor side X1, is positioned to cover the lower end of the glass 45, and covers the indoor side X2 surface, outdoor side X1 surface, and projected surface of the lower end of the glass 45.

[0242] With the lower end of the glass 45 positioned so as to be covered by the U-shaped portion 826, a sealant 827 is arranged between the visible surfaces of the lower end of the glass 45 on the indoor side X2 and the outdoor side X1 and the first inward protrusion 8232 on the indoor side X2 and the first inward protrusion 8232 on the outdoor side X1 of the fiber-reinforced core material 823 on the open side of the U-shaped portion 826, and a backup material 828 is arranged between the sealant 827 and the upper surface of the core-material-inward-direction extending plate 8231 of the fiber-reinforced core material 823 on the closed side of the U-shaped portion 826. Note that a glazing channel may be used as the sealant 827.

[0243] On the indoor side X2 and the outdoor side X1 of the glass 45, a mounting plate 8241 of the resin angle 824 is inserted between the first inward protrusion 8232 and the second inward protrusion 8233 and attached by press fitting. The resin angle 824 has the mounting plate 8241 that is disposed in the gap between the first inward protrusion 8232 and the second inward protrusion 8233 and extends in the vertical direction, and a cover plate 8242 that is connected to the upper end of the mounting plate 8241 in the vertical direction and extends in the forward direction.

[0244] The covering plate 8242 is formed to extend in the front direction along the upper end face of the sealing material 827 and the upper end faces of the first inward protrusion 8232 and the second inward protrusion 8233, and extends in the front direction so as to cover the portion sealed by the sealing material 827. An inner cover part 8212 (described later) of the wooden frame main body 821 is attached to the upper surface of the covering plate 8242.

[0245] The wooden frame body 821 is arranged around the fiber reinforced core material 823 so as to cover the fiber reinforced core material 823. The wooden frame body 821 has a pair of front-facing outer members 8211 that extend in the vertical direction (front-facing direction) along the indoor-side X2 surface and the outdoor-side X1 surface of the fiber reinforced core material 823, and a pair of inner cover parts 8212 that are arranged along the upper surfaces of the pair of resin angles 824. The pair of front-facing outer members 8211 and the pair of inner cover parts 8212 are made of wooden members (lumber).

[0246] The pair of inner cover portions 8212 are arranged above the sealant 827 to hide the sealant 827 that is arranged on the outdoor side X1 and the indoor side X2 of the lower end of the glass 45. The pair of inner cover portions 8212 are attached to the first inward protruding portion 8232 and the second inward protruding portion 8233 of the fiber reinforced core material 823 via resin angles 824, respectively.

[0247] The pair of inner cover portions 8212 extend in the forward direction along the upper surface of the cover plate 8242 of the resin angle member 824 attached to the upper sides of the first inward protrusion 8232 and the second inward protrusion 8233 of the fiber reinforced core material 823, on the indoor side X2 and the outdoor side X1 of the lower end portion of the glass 45, respectively. The pair of inner cover portions 8212 are attached to the upper surface of the cover plate 8242 of the resin angle member 824, respectively.

[0248] When the wooden inner cover part 8212 is disposed above the sealant 827 via the resin angle bracket 824 after the sealant 827 has been applied to the exterior side X1 and the interior side X2 of the lower end of the glass 45, the inner cover part 8212 is attached to the upper surface of the covering plate 8242 of the resin angle bracket 824 in advance, and then the mounting plate 8241 of the resin angle bracket 824 is inserted by press-fitting between the first inward protrusion 8232 and the second inward protrusion 8233 of the fiber reinforced core material 823. When the wooden inner cover part 8212 disposed above the sealant 827 is removed, the mounting plate 8241 of the resin angle bracket 824 is removed from the first inward protrusion 8232 and the second inward protrusion 8233 of the fiber reinforced core material 823 with the inner cover part 8212 attached to the upper surface of the covering plate 8242 of the resin angle bracket 824. In this way, the inner cover portion 8212 can be attached to the fiber reinforced core material 823 afterwards while attached to the resin angle 824 , or can be removed from the fiber reinforced core material 823 .

[0249] As described above, by attaching the wooden inner cover part 8212 to the upper side of the sealing material 827 via the resin angle 824, the wooden inner cover part 8212 can hide the sealing material 827 arranged on the outside side X1 and inside side X2 of the lower left and right ends of the glass 45, thereby improving the design.

[0250] Furthermore, since the wooden inner cover portion 8212 is attached to the fiber-reinforced core material 823 via the resin angle 824, the wooden inner cover portion 8212 can be attached to the fiber-reinforced core material 823 via the resin angle 824 while suppressing warping of the wooden inner cover portion 8212 compared to attaching the wooden inner cover portion 8212 directly to the fiber-reinforced core material 823.

[0251] In addition, the insulation performance can be improved by covering the sealing material 827 placed on the outside X1 and inside X2 of the lower end of the glass 45 with a resin angle 824 made of resin with excellent insulation properties and an inner wooden cover part 8212 with excellent insulation properties.

[0252] In this way, after applying the sealing material 827 to the outside-door side X1 and inside-door side X2 of the lower end of the glass 45, the wooden inner cover part 8212 can be attached to the fiber-reinforced core material 823 via the resin angle 824 made of resin, thereby creating an attachment structure for the wooden inner cover part 8212 that combines improved design, suppression of wood warping, and improved insulation.

[0253] As shown in Fig. 15, the door roller 9 is disposed below the fiber reinforced core material 823, which is disposed below the lower end of the glass 45. The door roller 9 is disposed on the lower surface of a core material projection direction extension plate 8231 of the fiber reinforced core material 823. In describing the door roller 9 of this embodiment, components similar to those of the door roller 5 shown in Fig. 8 described above are assigned corresponding reference numerals and description thereof will be omitted.

[0254] The door roller 9 has a wheel support frame 91 (reinforcement part) and a two-row wheel configuration part 92 in which two rows of wheel parts 921, 922 are provided in the projection direction and multiple sets of the two rows of wheel parts 921, 922 are lined up in the left-right direction.

[0255] The wheel support frame 91 is arranged below the fiber reinforced core material 823. The wheel support frame 91 supports two rows of wheel sections 921, 922, and by being provided below the fiber reinforced core material 823, reinforces the bottom frame 42F. The wheel support frame 91 is divided into two sections in the projection direction: an outdoor frame section 911 (outdoor exterior reinforcement section) and an indoor frame section 912 (indoor interior reinforcement section). Both the outdoor frame section 911 and the indoor frame section 912 are formed from a metal material such as aluminum.

[0256] A connecting member 913 (bridge member) is arranged between the outdoor frame portion 911 and the indoor frame portion 912. The connecting member 913 is formed from a material having heat insulating properties such as resin, and connects the outdoor frame portion 911 and the indoor frame portion 912. The connecting member 913 is provided below the fiber-reinforced core material 823.

[0257] The outdoor frame portion 911 is formed to open downwards, and has an outdoor side X1 wheel portion 921 disposed inside. The indoor frame portion 912 is formed to open downwards, and has an indoor side X2 wheel portion 922 disposed inside.

[0258] The upper surface of the outdoor frame portion 911 and the upper surface of the indoor frame portion 912 are formed at the same height position. The core material projection direction extension plate 8231 of the fiber reinforced core material 823 is arranged across the upper surface of the outdoor frame portion 911 and the upper surface of the indoor frame portion 912. In this embodiment, the door roller 9 is attached to the bottom frame 42F simply by placing the core material projection direction extension plate 9231 of the fiber reinforced core material 823 on the upper surface of the outdoor frame portion 911 and the upper surface of the indoor frame portion 912 of the wheel support frame 91. In detail, the door roller 9 is attached to the bottom frame 42F of the sliding shoji screen 4F without using fixing members such as screws, by placing the sliding shoji screen 4F on the upper surface of the outdoor frame portion 911 and the upper surface of the indoor frame portion 912 of the wheel support frame 91.

[0259] When performing maintenance on the door roller 9, the sliding door 4F is lifted, for example, by about 5 mm without removing it from the frame 2, and the wooden member attached to the lower end of the joining vertical frame 44F is removed, and the wheel support frame 91 of the door roller 9 is slid in the longitudinal direction of the lower frame 42F. This allows the door roller 9 to be removed from the longitudinal end of the lower frame 42F without removing the sliding door 4F from the frame 2.

[0260] Then, after repairing or replacing the door roller 9, the sliding shoji screen 4F is lifted, for example, by about 5 mm, without removing it from the frame 2, and the wheel support frame 91 of the door roller 9 is inserted from the longitudinal end of the bottom frame 42F, and the wheel support frame 91 of the door roller 9 is slid in the longitudinal direction of the bottom frame 42F. This allows the door roller 9 to be attached to the bottom frame 42F without removing the sliding shoji screen 4F from the frame 2. As described above, when performing maintenance on the door roller 9, the door roller 9 can be attached to or removed from the bottom frame 42F without removing the sliding shoji screen 4F from the frame 2, making maintenance of the door roller 9 easy.

[0261] Next, we will explain the fitting 1A of the eighth embodiment. The fitting 1A of the eighth embodiment is configured with two double sliding shoji screens 3X and 4X, whereas the fitting 1 of the first embodiment shown in Figure 1 is configured with a single sliding shoji screen 4.

[0262] As shown in Figures 16 and 17, the two sliding shoji screens 3X and 4X have a one-side sliding shoji screen 3X that is located on one side in the left-right direction (left side in Figures 14 and 15), and a other-side sliding shoji screen 4X that is located on the other side in the left-right direction (right side in Figures 14 and 15).

[0263] As shown in Figures 16 to 18, the other side sliding shoji screen 4X has the same configuration as the sliding shoji screen 4 of the first embodiment, so its description will be omitted. The one side sliding shoji screen 3X is configured to be movable left and right by providing the door rollers 5 of the sliding shoji screen 4 of the first embodiment in the fixed shoji screen 3 of the first embodiment. The description of the configuration of the one side sliding shoji screen 3X will be omitted, as the description of the configuration of the sliding shoji screen 4 of the first embodiment will be used.

[0264] The eighth embodiment is configured with two double sliding shoji screens 3X and 4X. The fitting 1A equipped with two double sliding shoji screens 3X and 4X can also achieve the same effects as the fitting 1 equipped with the single sliding shoji screen 4 of the first embodiment.
