[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. A sliding window 1 constituting a fixture according to one embodiment will be described. In this specification, the "visible direction" refers to the surface direction of the face panels 35, 45 of the sliding window 1 placed in an opening formed in the wall of a building, and the "visible direction" refers to the thickness direction (i.e., the depth direction) of the face panels 35, 45. The "visible direction" also refers to the indoor / outdoor direction. The "visible surface" refers to the surface of the sliding window 1 facing the outside and the inside, respectively, and the "visible surface" refers to the surface of the sliding window 1 extending in the indoor / outdoor direction. In the drawings, the outdoor side of the sliding window 1 is designated as the outdoor side X1, and the indoor side of the sliding window 1 is designated as the indoor side X2.

[0009] As shown in Figures 1 to 3, the sliding window 1 is made up of a frame 2 attached to an opening in a building frame (not shown), and two shoji screens fitted inside the frame 2: an outer shoji screen 3 (shoji screen) placed on the outside X1 of the room, and an inner shoji screen 4 (shoji screen) placed on the inside X2 of the room, as well as one screen 51 placed on the outside X1 of the outer shoji screen 3. The outer shoji screen 3 and inner shoji screen 4 can slide left and right (horizontally) within the frame 2 in the viewing direction.

[0010] 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. As shown in Figure 2, the upper frame 21 is provided with an exterior rail 211 and an interior rail 212. The upper frame 21 has a screen rail 213 on the exterior side X1 of the exterior rail 211. The exterior rail 211 is formed to protrude downward from the upper frame 21 at the exterior side X1 of the upper frame 21, and guides the upper end of the outer shoji screen 3. The interior rail 212 is formed to protrude downward from the upper frame 21 at the interior side X2 of the upper frame 21, and guides the upper end of the inner shoji screen 4.

[0011] The lower frame 22 is provided with an outdoor rail 221 and an indoor rail 222. The lower frame 22 has a screen rail 223 on the outdoor side X1 of the outdoor rail 221.

[0012] The screen door 51 is engaged with the screen door rails 213, 223 of the upper frame 21 and the lower frame 22 so as to be movable in the left-right direction.

[0013] As shown in Figures 1 to 3, the outer shoji screen 3 is constructed by fitting a panel 35 made of two pieces of glass inside a rectangular frame body 30 consisting of an upper frame 31, a lower frame 32, a vertical frame 33 located on the door tip side, and an outer joining frame 34, which is a vertical frame located on the door tail side. The outer shoji screen 3 is engaged with the outdoor rails 211, 221 of the upper frame 21 and the lower frame 22 so that it can move left and right. The lower frame 32 of the outer shoji screen 3 is provided with a door roller 36 that rolls on the outdoor rail 221 of the lower frame 22.

[0014] The inner shoji screen 4 is constructed by fitting a panel 45 made of two pieces of glass inside a rectangular frame body 40 consisting of an upper frame 41, a lower frame 42, a vertical frame 43 located at the door tip, and an inner joining frame 44 (vertical member) located at the door tail. The inner shoji screen 4 is engaged with the interior rails 212, 222 of the upper frame 21 and the lower frame 22 so that it can move left and right. The lower frame 42 of the inner shoji screen 4 is provided with a door roller 46 that rolls on the interior rail 222 of the lower frame 22.

[0015] Since the face plate 35 and the face plate 45, which are made up of two pieces of glass, have the same configuration, the following description will focus on the face plate 35, and the description of the face plate 45 will be omitted. The face material 35 has glass 351 that constitutes double-glazed glass, and a grating channel 352. Two pieces of glass 351 are arranged on the outside and inside of the room, sandwiching a spacer 354 between them. The grating channel 352 is a rubber gasket that is roughly U-shaped in cross section and holds the two pieces of glass together. The grating channel 352 is inserted between a lower extension 3114 that constitutes the exterior side material holding portion of the frame 30 and a step 3134 of the wood mounting attachment 313 (described below), and holds the edge of the glass 351.

[0016] The combination of the outer interlocking frame 34 and the upper frame 31, and the combination of the outer interlocking frame 34 and the lower frame 32 are combined in a so-called vertically aligned structure, in which the upper end of the outer interlocking frame 34 is positioned outside the horizontal end of the upper frame 31 and the lower end of the outer interlocking frame 34 is positioned outside the horizontal end of the lower frame 32.

[0017] In the outer shoji screen 3, when the upper frame 31 is assembled to the upper end of the outer meeting frame 34 or when the lower frame 32 is assembled to the lower end of the outer meeting frame 34, part of the horizontal end of the upper frame 31 (metal frame material 311, wooden frame material 312) or part of the horizontal end of the lower frame 32 (metal frame material 321, wooden frame material 322) is inserted into the inside of the upper end or lower end of the outer meeting frame 34 and assembled.

[0018] As shown in Figures 2 and 3, the upper frame 31, lower frame 32, vertical frame 33 located on the door edge side, and outer joining frame 34 (vertical member) of the outer shoji screen 3 each have a composite structure in which wooden frame members 312, 322, 332, 342 as indoor members are attached to the indoor side X2 of metal frame members 311, 321, 331, 341 as outdoor members via wooden mounting attachments 313, 323, 333, 343 as indoor side member holding parts. The upper frame 41, lower frame 42, vertical frame 43 located on the door edge side, and inner joining frame 44 of the inner shoji screen 4 each have a composite structure in which wooden frames 412, 422, 432, 442, and 445 are attached as indoor members to the indoor side X2 of metal frames 411, 421, 431, and 441 via wood mounting attachments 413, 423, 433, and 443 that serve as indoor side material holders. The outer shoji screen 3 and inner shoji screen 4 are made up of composite sashes of aluminum and wood.

[0019] In this embodiment, for example, the metal frame materials 311, 321, 331, 341, 411, 421, 431, 441 are made of aluminum material, and the frames of the outer shoji 3 (upper frame 31, lower frame 32, vertical frame 33 located on the door edge side and outer joining frame 34) and the frames of the inner shoji 4 (upper frame 41, lower frame 42, vertical frame 43 located on the door edge side and inner joining frame 44) are made of a composite structure of aluminum and wood. This gives the outer shoji 3 and inner shoji 4 excellent heat insulation and moisture resistance.

[0020] Metal frame 311 and metal frame 411 have the same configuration. Metal frame 321 and metal frame 421 have the same configuration. Wooden frame 312 and wooden frame 412 have the same configuration. Wooden frame 322 and wooden frame 422 have the same configuration. Wood mounting attachment 313 and wood mounting attachment 413 have the same configuration. Wood mounting attachment 323 and wood mounting attachment 423 have the same configuration. For this reason, in the following explanation, we will explain metal frame material 311, metal frame material 321, wooden frame material 312, wooden frame material 322, wood mounting attachment 313, and wood mounting attachment 323, and will omit explanation of metal frame material 411, metal frame material 421, wooden frame material 412, wooden frame material 422, wood mounting attachment 413, and wood mounting attachment 423.

[0021] The upper end of the metal frame 311 facing the interior has a U-shaped engagement portion 3111 that opens upward. The lower end of the metal frame 311 facing the interior has an engagement portion 3112 that extends downward. The wood mounting attachment 313 is made of, for example, metal or resin. If metal, it may be made of, for example, aluminum, but is not limited to, aluminum. Because the wood mounting attachment 313 is made of metal or resin, the processing precision of the wood mounting attachment 313 as an interior side panel holder can be increased compared to when the glass panel 35 is configured with a wooden interior side panel holder, and deterioration of the wood mounting attachment 313 over time can be reduced. As a result, the glass panel 35 can be prevented from easily coming off the upper frame 31. Furthermore, if the wood mounting attachment 313 is made of resin, the exterior side of the wooden frame 312 can be prevented from being cooled from the outside, thereby improving insulation.

[0022] The upper end of the wood mounting attachment 313 on the outdoor side has an engaged portion 3131 that extends downward. The middle portion of the wood mounting attachment 313 on the outdoor side in the vertical direction has a U-shaped engaged portion 3132 that opens upward.

[0023] The engaging portion 3111 engages with the open portion of the engaging portion 3112. The engaging portion 3112 engages with the open portion of the engaged portion 3131. By this engagement, the wood mounting attachment 313 can be detachably engaged with the metal frame 311.

[0024] The upper end of the wood mounting attachment 313 on the indoor side has an L-shaped locking portion 3133 that extends downward toward the indoor side. The lower end of the wood mounting attachment 313 on the indoor side has a step portion 3134 that protrudes one step toward the indoor side.

[0025] Wooden frame 312 is made of a wooden plate. The upper end of wooden frame 312 on the outdoor side has latched portion 3121 with a shape similar to latching portion 3133, with which latching portion 3133 can engage. The lower end of wooden frame 312 on the indoor side has step portion 3122 with a shape similar to step portion 3134, with which step portion 3134 can engage. The lower end of step portion 3122 is positioned to coincide with the lower end of step portion 3134.

[0026] The locking portion 3133 engages with the locked portion 3121. The step portion 3134 engages with the step portion 3122. In addition to these engagements, the wood mounting attachment 313 is fixed to the wooden frame 312 by passing a screw 314 through a through hole formed in the wood mounting attachment 313 and screwing it into the wooden frame 312.

[0027] Because the wood mounting attachment 313 can be detachably engaged with the metal frame 311, the wooden frame 312 to which the wood mounting attachment 313 is fixed can be detached from and replaced with the metal frame 311. In other words, the wood mounting attachment 313 to which the wooden frame 312 is fixed can be removed from the metal frame 311, and another wood mounting attachment 313, or another wood mounting attachment (not shown) that has a portion shaped similarly to the portion of the wood mounting attachment 313 that engages with the metal frame 311 and a remaining portion shaped differently from the wood mounting attachment 313, can be detachably attached to the metal frame 311. The other wood mounting attachment 313 and the other wood mounting attachment are prepared in advance with an interior member made of a non-metallic material different from that of the wooden frame 312, such as resin or stone, fixed thereto. This makes it possible to use wooden or resin indoor components by attaching and detaching the wood mounting attachment 313 to and replacing it with the metal frame 311 as needed. This makes it easy to replace indoor components even during renovations, etc. In particular, when the indoor component made of the non-metallic material described above is used by being fixed to the other wood mounting attachment 313 described above, the wood mounting attachment 313 to which the wooden frame 312 is fixed is the same as the other wood mounting attachment 313, so it is possible to reduce capital investment for manufacturing the product and costs due to an increase in the number of parts.

[0028] The upper end of the metal frame 321 facing the interior of the room has an engaging portion 3211 extending upward. The lower end of the metal frame 321 facing the interior of the room has an engaging portion 3212 extending downward. The wood mounting attachment 323 is made of, for example, metal or resin. If made of metal, it may be made of, for example, aluminum, but is not limited to, aluminum. Because the wood mounting attachment 323 is made of metal or resin, the processing precision of the wood mounting attachment 323 as an interior side panel holder can be increased compared to when the glass panel 35 is made of a wooden interior side panel holder, and deterioration of the wood mounting attachment 323 over time can be reduced. As a result, the glass panel 35 is less likely to come loose from the lower frame 32. Furthermore, if the wooden mounting attachment 323 is made of resin, it is possible to prevent the outdoor side of the wooden frame 322 from being cooled from the outside of the room, thereby improving the heat insulation.

[0029] The middle part in the vertical direction on the outdoor side of the wood mounting attachment 323 has a U-shaped engaged part 3231 that opens downward. The lower end part on the outdoor side of the wood mounting attachment 323 has a U-shaped engaged part 3232 that opens downward.

[0030] The engaging portion 3211 engages with the opening of the engaged portion 3231. The engaging portion 3212 engages with the opening of the engaged portion 3231. By this engagement, the wood mounting attachment 323 can be detachably engaged with the metal frame 321.

[0031] The upper end of the wood mounting attachment 323 on the indoor side has a step 3234 that protrudes one step toward the indoor side. The lower end of the wood mounting attachment 323 on the indoor side has an L-shaped locking part 3233 that extends downward toward the indoor side.

[0032] Wooden frame 322 is made of a wooden plate. The lower end of wooden frame 322 on the outdoor side has latched portion 3221 with a shape similar to that of latching portion 3233, with which latching portion 3233 can engage. The upper end of wooden frame 322 on the indoor side has step portion 3222 with a shape similar to that of step portion 3234, with which step portion 3234 can engage. The upper end of step portion 3222 is positioned to coincide with the lower end of step portion 3234.

[0033] The locking portion 3233 engages with the locked portion 3221. The step portion 3234 engages with the step portion 3222. In addition to these engagements, the wood mounting attachment 323 is fixed to the wooden frame 322 by passing a screw 324 through a through hole formed in the wood mounting attachment 323 and screwing it into the wooden frame 322.

[0034] Because the wood mounting attachment 323 can be detachably engaged with the metal frame 321, the wooden frame 322 to which the wood mounting attachment 323 is fixed can be detached from and replaced with the metal frame 321. In other words, the wood mounting attachment 323 to which the wooden frame 322 is fixed can be removed from the metal frame 321, and another wood mounting attachment 323, or another wood mounting attachment (not shown) that has a portion shaped similarly to the portion of the wood mounting attachment 323 that engages with the metal frame 321 and another portion shaped differently from the wood mounting attachment 323, can be detachably attached to the metal frame 321. The other wood mounting attachment 323 and the other wood mounting attachment are prepared in advance with an interior member made of a non-metallic material different from that of the wooden frame 322, such as resin or stone, fixed thereto. This makes it possible to use wooden or resin indoor components by attaching and detaching the wood mounting attachment 323 to and replacing it with the metal frame 321 as needed. This makes it easy to replace indoor components even during renovations, etc. In particular, when the indoor component made of the non-metallic material described above is used by being fixed to the other wood mounting attachment 323 described above, the wood mounting attachment 323 to which the wooden frame 322 is fixed is the same as the other wood mounting attachment 323, so it is possible to reduce the increase in capital investment for product manufacturing and the increase in costs due to the increase in the number of parts.

[0035] The combination of the inner interlocking frame 44 and the upper frame 41, and the combination of the inner interlocking frame 44 and the lower frame 42 are combined in a so-called vertically aligned structure, in which the upper end of the inner interlocking frame 44 is positioned outside the horizontal end of the upper frame 41 and the lower end of the inner interlocking frame 44 is positioned outside the horizontal end of the lower frame 42.

[0036] In the case of the inner shoji screen 4, when the upper frame 41 is assembled to the upper end of the inner joining frame 44 or when the lower frame 42 is assembled to the lower end of the inner joining frame 44, part of the horizontal end of the upper frame 41 (metal frame material 411, wooden frame material 412) or part of the horizontal end of the lower frame 42 (metal frame material 421, wooden frame material 422) is inserted into the inside of the upper end or lower end of the inner joining frame 44 and assembled.

[0037] The metal frame 331 of the vertical frame 33 and the metal frame 431 of the vertical frame 43 are symmetrical. The wooden frame 332 and the wooden frame 432 are symmetrical. The wood mounting attachment 333 and the wood mounting attachment 433 are symmetrical. For this reason, in the following explanation, the metal frame 331, the wooden frame 332, and the wood mounting attachment 333 will be described, and explanations of the metal frame 431, the wooden frame 432, and the wood mounting attachment 433 will be omitted.

[0038] As shown in Figure 3, the door-tip side end of the metal frame 331 on the indoor side has an L-shaped engaging part 3311, with the end extending toward the door-tip side extending toward the outdoor side. The part near the door-tail side end of the metal frame 331 on the indoor side has an engaging part 3312 extending toward the door-tail side.

[0039] The wood mounting attachment 333 is made of, for example, metal or resin. If it is made of metal, it is made of, for example, aluminum, but is not limited to, aluminum. Because the wood mounting attachment 333 is made of metal or resin, the processing precision of the wood mounting attachment 333 as an interior side panel holder can be increased and deterioration of the wood mounting attachment 333 over time can be suppressed compared to when the glass panel 35 is configured with a wooden interior side panel holder. As a result, the glass panel 35 can be prevented from easily coming off the vertical frame 33. Furthermore, if the wood mounting attachment 333 is made of resin, it can prevent the exterior side of the wooden frame 332 from being cooled from the outside, thereby improving insulation.

[0040] The outside end of the wood mounting attachment 333 on the door front side has an L-shaped engaged part 3331, with the end that extends toward the door trailing edge extending toward the room. The outside end of the wood mounting attachment 333, midway between the door front and door trailing edge ends, has an L-shaped engaged part 3332, with the end that extends toward the door front side.

[0041] The engaging portion 3311 engages with the engaged portion 3331. The engaging portion 3312 engages with the engaged portion 3332. By this engagement, the wood mounting attachment 333 can be detachably engaged with the metal frame 331.

[0042] The end of the wood mounting attachment 333 on the indoor side of the door leading edge has an L-shaped locking portion 3333 whose end extends toward the indoor side and the end toward the door trailing edge. The end of the wood mounting attachment 333 on the indoor side of the door trailing edge has a step portion 3334 that protrudes one step toward the indoor side.

[0043] The wooden frame 332 is made of a wooden plate. The outside end of the wooden frame 332 has a latched portion 3321 with a shape similar to that of the latching portion 3333, with which the latching portion 3333 can latch. The inside end of the wooden frame 332 has a step 3322 with a shape similar to that of the step 3334, with which the step 3334 can latch. The end of the step 3322 is located closer to the end of the shoji screen 3 than the end of the step 3334, and is positioned so as to coincide with the end of the grating channel 352 with its edge.

[0044] The locking portion 3333 locks into the locked portion 3321. The step portion 3334 locks into the step portion 3322. In addition to these locking mechanisms, the wood mounting attachment 333 is fixed to the wooden frame 332 by passing a screw 334 through a through-hole formed in the wood mounting attachment 333 and screwing it into the wooden frame 332.

[0045] Because the wood mounting attachment 333 can be detachably engaged with the metal frame 331, the wooden frame 332 to which the wood mounting attachment 333 is fixed can be detached from and replaced with the metal frame 331. That is, the wood mounting attachment 333 to which the wooden frame 332 is fixed can be removed from the metal frame 331, and another wood mounting attachment 333, or another wood mounting attachment (not shown) having a portion shaped similarly to the portion of the wood mounting attachment 333 that engages with the metal frame 331 but a remaining portion shaped differently from the wood mounting attachment 333, can be detachably attached to the metal frame 331. The other wood mounting attachment 333 and the other wood mounting attachment are prepared in advance with an interior member made of a non-metallic material different from that of the wooden frame 332, such as resin or stone, fixed thereto. This allows wooden or resin indoor components to be used by attaching and detaching the wood mounting attachment 333 to and replacing it with the metal frame 331 as needed. This makes it easy to replace indoor components even during renovations, etc. In particular, when the indoor component made of the non-metallic material described above is used by being fixed to the other wood mounting attachment 333 described above, the wood mounting attachment 333 to which the wooden frame 332 is fixed is the same as the other wood mounting attachment 333, so it is possible to reduce the increase in capital investment for product manufacturing and the increase in costs due to the increase in the number of parts.

[0046] As shown in Figure 3, the indoor end of the metal frame material 341 of the outer frame 34 has a U-shaped engaging portion 3411 that opens toward the edge of the shoji screen 3. Both ends of the opening of the engaging portion 3411 are formed in a groove shape.

[0047] The wood mounting attachment 343 is made of, for example, metal or resin. If it is made of metal, it is made of, for example, aluminum, but is not limited to, aluminum. Because the wood mounting attachment 343 is made of metal or resin, the processing precision of the wood mounting attachment 343 as an interior side panel holder can be increased and deterioration of the wood mounting attachment 343 over time can be suppressed compared to when the glass panel 35 is configured with a wooden interior side panel holder. As a result, it is possible to prevent the glass panel 35 from easily coming off the exterior joining frame 34. Furthermore, if the wood mounting attachment 343 is made of resin, it is possible to suppress cooling of the exterior side of the wooden frame 342 from the outside, thereby improving insulation.

[0048] As shown in Fig. 3, the wood mounting attachment 343 has a tail end side 3431 and a panel holding portion 3435. Both ends of the tail end side 3431 in the projection direction extend toward the inside and outside of the room, respectively, and these portions engage with groove-shaped portions at both ends of the opening of the engagement portion 3411 of the metal frame 341. This engagement allows the wood mounting attachment 343 to be detachably engaged with the metal frame 341. Furthermore, screws 344 pass through through holes formed in the tail end side 3431 and screw into the wooden frame 342, thereby fixing the wood mounting attachment 343 to the wooden frame 342. The wooden frame 342 is made of a wooden plate.

[0049] Because the wood mounting attachment 343 can be detachably engaged with the metal frame 341, the wooden frame 342 to which the wood mounting attachment 343 is fixed can be detached from and replaced with the metal frame 341. That is, the wood mounting attachment 343 to which the wooden frame 342 is fixed can be removed from the metal frame 341, and another wood mounting attachment 343, or another wood mounting attachment (not shown) having a portion shaped similarly to the portion of the wood mounting attachment 343 that engages with the metal frame 341 but a remaining portion shaped differently from the wood mounting attachment 343, can be detachably attached to the metal frame 341. The other wood mounting attachment 343 and the other wood mounting attachment are prepared in advance with an interior member made of a non-metallic material different from that of the wooden frame 342, such as resin or stone, fixed thereto. This allows the use of wooden or resin indoor components by attaching and detaching the wood mounting attachment 343 to and replacing it with the metal frame 341 as needed. This makes it easy to replace indoor components even during renovations, etc. In particular, when the indoor component made of the non-metallic material described above is used by being fixed to the other wood mounting attachment 343 described above, the wood mounting attachment 343 to which the wooden frame 342 is fixed is the same as the other wood mounting attachment 343, so it is possible to reduce the increase in capital investment for manufacturing the product and the increase in costs due to the increase in the number of parts.

[0050] As shown in Figure 3, the outside door trailing edge end of the metal frame material 441 of the interior door frame 44 has an engagement part 4411 that extends toward the outside and the door tip of the shoji screen 4. The inside door trailing edge end of the metal frame material 441 of the interior door frame 44 has a U-shaped engagement part 4412 that opens toward the door tip of the shoji screen 4.

[0051] The wood mounting attachment 443 is made of, for example, metal or resin. If it is made of metal, it is made of, for example, aluminum, but is not limited to, aluminum. Because the wood mounting attachment 443 is made of metal or resin, the processing precision of the wood mounting attachment 443 as an interior side panel holder can be increased and deterioration of the wood mounting attachment 443 over time can be suppressed compared to when the glass panel 45 is configured with a wooden interior side panel holder. As a result, it is possible to prevent the glass panel 45 from easily coming off the interior joining frame 44. Furthermore, if the wood mounting attachment 443 is made of resin, it is possible to suppress cooling of the exterior side of the wooden frame 442 from the outside, thereby improving insulation.

[0052] As shown in FIG. 3, the wood mounting attachment 443 has an engaged portion 4431, a surface material holding portion 4432, an engaged portion 4433, a step portion 4434, a locking portion 4435, and a locking portion 4436.

[0053] The engaged portion 4431 is formed in a U-shape with its end extending toward the leading edge of the shoji screen 4 extending into the room and then further toward the trailing edge, and engages with the engaging portion 4411. The surface material holding portion 4432 extends toward the leading edge of the shoji screen 4 at the indoor-side end of the wood mounting attachment 443 and holds the surface material 45 together with the metal frame material 441. The engaged portion 4433 is located at the boundary between the surface material holding portion 4432 and the step portion 4434, and is formed in a U-shape that opens toward the leading edge of the shoji screen 4, and engages with the engaging portion 4412. The step portion 4434 protrudes one step toward the indoor side. The locking portion 4435 is formed at the end of the wood mounting attachment 443 on the outdoor side that extends further toward the trailing edge from the trailing edge end of the shoji screen 4. The locking portion 4436 is formed by an end portion extending from the rear end side end of the shoji screen 4 on the indoor side of the wood mounting attachment 443 toward the outdoor side.

[0054] The wooden frame 442 is made of a wooden plate. The outdoor end of the wooden frame 442 has a step 4421 of the same shape as the step 4434, with which the step 4434 can engage. When a screw 444 passes through a through hole in the step 4434 and threads into the step 4421, the wooden frame 442 is fixed to the indoor facing surface (surface material holding portion 4432, step 4434) of the wood mounting attachment 443, and covers the facing surface.

[0055] The wooden frame 445 is made of a plank of wood. The end of the wooden frame 445 on the outside of the room, closer to the trailing edge of the shoji screen 4, has a latched portion 4451 shaped similarly to the latching portion 4435, with which the latching portion 4435 can latch. The end of the wooden frame 445 on the inside of the room, closer to the trailing edge of the shoji screen 4, has a latched portion 4452 shaped similarly to the latching portion 4436, with which the latching portion 4436 can latch. When the latched portion 4451 is latched to the latching portion 4435 and the latched portion 4452 is latched to the latching portion 4436, the wooden frame 445 is fixed to the visible surface of the wood mounting attachment 443 and covers the visible surface.

[0056] The wooden frame 442 covers the visible surface of the interior joining frame 44 by covering the visible surface of the wooden mounting attachment 443, and the wooden frame 445 covers the visible surface of the interior joining frame 44 by covering the visible surface of the wooden mounting attachment 443, so the wooden frame 442 and the wooden frame 445 can be constructed from mutually independent members. This makes it possible to easily process wood to manufacture the wooden frame 442 and the wooden frame 445, and improves the yield of raw material.

[0057] Next, a second embodiment of the present disclosure will be described. In the second embodiment, the configurations of the wooden frame members 332A and 432A of the vertical frame members 33A and 43A are different from the configurations of the wooden frame members 332 and 432 in the first embodiment. Since the configuration other than this is the same as in the first embodiment, the same members are assigned the same reference numerals and descriptions thereof will be omitted.

[0058] The wooden frame 332A is fixed to the wood mounting attachment 333A only by screws 334A. Therefore, the wooden frame 332A does not have the locked portion 3321 of the wooden frame 332 in the first embodiment. Furthermore, the wood mounting attachment 333A does not have the locking portion 3333 of the wood mounting attachment 333 in the first embodiment. Similarly, the wooden frame 432A is fixed to the wood mounting attachment 433A only by screws 434A. The end of the wooden frame 432A in the left viewing direction (left direction in FIG. 4) is positioned to coincide with the end of the wood mounting attachment 433A in the same direction.

[0059] Next, a third embodiment of the present disclosure will be described. In the third embodiment, the configurations of the wooden stiles 332B and 432B of the vertical stiles 33B and 43B are different from the configurations of the wooden stiles 332 and 432 in the first embodiment. The configuration other than this is the same as in the first or second embodiment, so the same members are assigned the same reference numerals and descriptions thereof will be omitted.

[0060] The wooden frame 332B is fixed only by screws 334B to a joint fitting 3311B that protrudes from the metal frame 331B toward the interior of the room, without using a wood mounting attachment. The joint fitting 3311B is integrally molded with the metal frame 331B. Note that the joint fitting 3311B does not have to be integrally molded with the metal frame 331B; in this case, the joint fitting and the metal frame may be separate pieces. The wooden frame 432B is fixed to the wood mounting attachment 433A only by screws (not shown). The end of the wooden frame 432B in the left direction (left direction in FIG. 5) coincides with the end of the grating channel 452 in the same direction.

[0061] Next, a fourth embodiment of the present disclosure will be described. In the fourth embodiment, the configurations of the wooden frames 332C and 432C of the vertical frames 33C and 43C are different from the configurations of the wooden frames 332 and 432 in the first embodiment. Other configurations are the same as those in the first to third embodiments, so the same members are assigned the same reference numerals and descriptions thereof will be omitted.

[0062] Wooden frame 332C is fixed only by screws 334C to joint fitting 3311B that protrudes from metal frame 331B toward the interior of the room, without using a wood mounting attachment. A recess 3365C is formed in the end surface of wooden frame 332C facing the interior of the room, and recess 3365C is fixed to recess 3365C.

[0063] Wooden frame 432C is fixed to wood mounting attachment 433A only with screws (not shown). A recess 4325C is formed in the indoor-side end surface of wooden frame 432C, and recessed part 436C is fixedly installed in recess 4325C. The end of wooden frame 432C in the left facing direction (left direction in Figure 6) is positioned to coincide with the end of wood mounting attachment 433A in the same direction.

[0064] Next, a fifth embodiment of the present disclosure will be described. In the fifth embodiment, the configuration of the inner joining frame 44D differs from the configuration of the inner joining frame 44 in the first embodiment. Since the other configurations are the same as those in the first to third embodiments, the same components are denoted by the same reference numerals and their description will be omitted.

[0065] The interior joining frame 44D has wooden frame member 442D, wooden frame member 445D, and wooden frame member 446D. Wooden frame member 442D is fixed to metal frame member 4441D via wood mounting attachment 447D. Wooden frame member 445D is fixed to metal frame member 4441D via wood mounting attachment 443D. Wooden frame member 446D is fixed to metal frame member 4441D via wood mounting attachment 448D. As a result, the visible surface of interior joining frame 44D on the interior side is covered by wooden frame member 442D. The visible surface of interior joining frame 44D is covered by wooden frame member 445D and wooden frame member 446D.

[0066] The wooden frame 442D has protrusions 4421D and 4422D at both ends in the left and right directions of the front view that protrude toward the outside of the room. The end of the wooden frame 445D facing the room in the front view has a protrusion 4451D. The protrusion 4451D fits with the protrusion 4421D. Furthermore, the end of the wooden frame 446D facing the room in the front view has a protrusion 4461D. The protrusion 4461D fits with the protrusion 4422D. Because the protrusions 4451D and 4421D fit together, and the protrusions 4461D and 4422D fit together in this way, even if there is some variation in the dimensions of the wooden frame 442D, the wooden frame 445D, and the wooden frame 446D, it is possible to prevent gaps between these components from being exposed. In addition, when the inner frame 44D is grasped and operated to open or close the shoji screen, it is possible to prevent the wooden frame 442D from shifting left or right in the visible direction.

[0067] Next, a sixth embodiment of the present disclosure will be described. In the sixth embodiment, the configuration of the inner stile 44E is different from the configuration of the inner stile 44D in the fifth embodiment. Since the other configurations are the same as those in the fifth embodiment, the same components are assigned the same reference numerals and descriptions thereof will be omitted.

[0068] The end faces on the outside of the room at both ends of the left and right directions in the viewing direction of wooden frame 442E are respectively composed of flat surfaces 4421E and 4422E. The end face on the inside of the room in the viewing direction of wooden frame 445E is composed of flat surface 4451E. Flat surface 4451E abuts against flat surface 4421E with a surface. The end face on the inside of the room in the viewing direction of wooden frame 446E is composed of flat surface 4461E. Flat surface 4461E abuts against flat surface 4422E with a surface. By flattening the end faces of wooden frame 442E, wooden frame 445E, and wooden frame 446E so that they abut with such surfaces, it is possible to facilitate the processing of these wooden members.

[0069] Next, a seventh embodiment of the present disclosure will be described. In the seventh embodiment, the configurations of the wooden frames 312F, 412F of the upper frames 31F, 41F and the wooden frames 322F, 422F of the lower frames 32F, 42F are different from the configurations of the wooden frames 312, 412 of the upper frames 31, 41 and the wooden frames 322, 422 of the lower frames 32, 42 in the first embodiment. Other configurations are the same as in the first embodiment, so the same components are denoted by the same reference numerals and descriptions thereof will be omitted.

[0070] The upper frame 31F and the upper frame 41F have the same configuration. Therefore, we will explain the upper frame 31F and omit the explanation of the upper frame 41F. Also, the lower frame 32F and the lower frame 42F have the same configuration. Therefore, we will explain the lower frame 32F and omit the explanation of the lower frame 42F.

[0071] The wooden frame 312F is fixed to the wood mounting attachment 313F only by screws 314F. Therefore, the wooden frame 312F does not have the locked portion 3121 of the wooden frame 312 in the first embodiment. Furthermore, the wood mounting attachment 313F does not have the locking portion 3133 of the wood mounting attachment 313 in the first embodiment. The lower end of the wooden frame 312F in the vertical direction is positioned to coincide with the lower end of the grating channel 352 located at the upper end of the face plate 35. This allows the wooden frame 312F to cover the grating channel 352, thereby enhancing the design.

[0072] Similarly, the wooden frame 322F is fixed to the wood mounting attachment 323F only by screws 324F. Therefore, the wooden frame 322F does not have the locked portion 3221 of the wooden frame 322 in the first embodiment. Furthermore, the wood mounting attachment 323F does not have the locking portion 3233 of the wood mounting attachment 323 in the first embodiment. The upper end of the wooden frame 322F in the vertical direction is positioned to coincide with the upper end of the grating channel 352 located at the lower end of the face plate 35. As a result, the wooden frame 322F covers the grating channel 352, thereby enhancing the design.

[0073] Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate. For example, in this embodiment, the outdoor member is composed of metal frames 311, 321, 331, 341, 411, 421, 431, 441, and the indoor member is composed of wooden frames 312, 322, 332, 342, 412, 422, 432, 442, 445, but this configuration is not limiting. For example, instead of a shoji screen, a frame may be composed of an outdoor member, an indoor member, and an attachment that engages with the outdoor member. In this case, the outdoor member may be made of metal, the indoor member may be made of a non-metallic material, and the attachment may be made of metal or resin. The wooden frame may be fixed to the wooden attachment using double-sided tape or adhesive. In addition, when the interior member is made of resin, the wood mounting attachment may be made of resin and molded integrally with the interior member. [Explanation of symbols]
