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

[0009] As shown in Figures 1 to 3, the sliding window 1 is composed of a frame 2 attached to an opening in a building frame (not shown), and two shoji screens, an outer shoji screen 3 (shoji screen) placed on the outside side X1 of the room and an inner shoji screen 4 (shoji screen) placed on the inside side X2 of the room, fitted inside the frame 2, as well as one screen door 51 placed on the outside side X1 of the outer shoji screen 3. The outer shoji screen 3 and the inner shoji screen 4 are slidable left and right (horizontally) within the frame 2 in the front 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 Fig. 2, an exterior rail 211 and an interior rail 212 are provided on the upper frame 21. 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 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 screen 4.

[0011] The lower frame 22 is provided with an exterior rail 221 and an interior rail 222. The lower frame 22 has a screen rail 223 on the exterior side X1 of the exterior 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 screen 3 is constructed by fitting a panel 35 made of two pieces of glass inside a frame body 30 which is a rectangular frame assembly of an upper frame 31, a lower frame 32, a vertical frame 33 located on the door end side, and an outer meeting frame 34, which is a vertical frame located on the door tail side. The outer screen 3 is engaged with the outdoor rails 211, 221 of the upper frame 21 and the lower frame 22 so as to be movable in the left-right direction. The lower frame 32 of the outer screen 3 is provided with a door roller 36 which rolls on the outdoor rail 221 of the lower frame 22.

[0014] The inner screen 4 is constructed by fitting a panel 45 made of two pieces of glass inside a frame body 40 made of an upper frame 41, a lower frame 42, a vertical frame 43 located on the door end side, and an inner meeting frame 44 (vertical member) located on the door tail side, assembled into a rectangular shape. The inner screen 4 is engaged with the interior rails 212, 222 of the upper frame 21 and the lower frame 22 so as to be movable in the left-right direction. The lower frame 42 of the inner screen 4 is provided with a wheel 46 that rolls on the interior rail 222 of the lower frame 22.

[0015] Since face material 35 and face material 45, which are made of two pieces of glass, have the same configuration, the following description will focus on face material 35 and omit the description of face material 45. The face material 35 has glass 351 that constitutes double glazing, and a grating channel 352. Two pieces of glass 351 are arranged on the outside and inside of the room with a spacer 354 sandwiched between them. The grating channel 352 is a rubber packing that holds the two pieces of glass and has a roughly U-shaped cross section. 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 a wood mounting attachment 313 described below, and holds the end face 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-oriented 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 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, a part of the horizontal end of the upper frame 31 (metal frame material 311, wooden frame material 312) or a 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 arranged on the door end side, and outer meeting frame 34 (vertical member) of the outer screen 3 each have a composite structure in which wooden frame members 312, 322, 332, 342 as indoor side members are attached to the indoor side X2 of metal frame members 311, 321, 331, 341 as outdoor side members via wood mounting attachments 313, 323, 333, 343 as indoor side member holding parts. The upper frame 41, lower frame 42, vertical frame 43 arranged on the door end side, and inner meeting frame 44 of the inner screen 4 each have a composite structure in which wooden frames 412, 422, 432, 442 and 445 as indoor side members are attached to the indoor side X2 of metal frames 411, 421, 431, 441 via wood mounting attachments 413, 423, 433, 443 as indoor side material retainers. The outer screen 3 and inner screen 4 form 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 screen 3 (upper frame 31, lower frame 32, vertical frame 33 arranged on the door end side, and outer meeting frame 34) and the frames of the inner screen 4 (upper frame 41, lower frame 42, vertical frame 43 arranged on the door end side, and inner meeting frame 44) are made of a composite structure of aluminum and wood. This gives the outer screen 3 and inner screen 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 describe metal frame 311, metal frame 321, wooden frame 312, wooden frame 322, wood mounting attachment 313, and wood mounting attachment 323, and will omit explanations of metal frame 411, metal frame 421, wooden frame 412, wooden frame 422, wood mounting attachment 413, and wood mounting attachment 423.

[0021] The upper end of the metal frame 311 on the indoor side has a U-shaped engagement part 3111 that opens upward. The lower end of the metal frame 311 on the indoor side has an engagement part 3112 that extends downward. The wood mounting attachment 313 is made of, for example, metal or resin, and when made of metal, it is made of, for example, aluminum material, but is not limited to aluminum material. Since the wood mounting attachment 313 is made of metal or resin, the processing accuracy of the wood mounting attachment 313 as the indoor side material holding part can be increased compared to when the glass surface material 35 is made of a wooden indoor side material holding part, and the deterioration of the wood mounting attachment 313 over time can be suppressed. As a result, it is possible to suppress the glass surface material 35 from easily coming off the upper frame 31. Furthermore, when the wood mounting attachment 313 is made of resin, it is possible to suppress the outdoor side surface of the wooden frame 312 from being cooled from the outdoor side, and it is possible to improve the insulation.

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

[0023] The engaged portion 3131 engages with the opening of the engaging portion 3111. The engaging portion 3112 engages with the opening 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 plank of wood. The upper end of wooden frame 312 on the outdoor side has locked portion 3121 shaped similarly to locking portion 3133 with which locking portion 3133 can engage. The lower end of wooden frame 312 on the indoor side has step 3122 shaped similarly to step 3134 with which step 3134 can engage. The lower end of step 3122 is positioned to coincide with the lower end of step 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 into the wooden frame 312.

[0027] Since the wood mounting attachment 313 can be detachably engaged with the metal frame 311, the wood frame 312 to which the wood mounting attachment 313 is fixed can be detached from and replaced with the metal frame 311. That is, the wood mounting attachment 313 to which the wood 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) having a portion with a shape similar to that of the portion of the wood mounting attachment 313 that engages with the metal frame 311 and another portion with a shape different from that of the wood mounting attachment 313 can be detachably attached to the metal frame 311. The above-mentioned other wood mounting attachment 313 and other wood mounting attachment are prepared in advance by fixing an interior side member made of a non-metallic material different from that of the wooden frame 312, such as resin or stone. This allows the use of 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 the indoor components even during renovations. In particular, when the indoor components made of the non-metallic material described above are 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 that it is possible to suppress the increase in capital investment for manufacturing the product and the increase in costs due to the increase in the number of parts.

[0028] The upper end of the metal frame 321 on the indoor side has an engagement portion 3211 extending upward. The lower end of the metal frame 321 on the indoor side has an engagement portion 3212 extending downward. The wood mounting attachment 323 is made of, for example, metal or resin, and when made of metal, it is made of, for example, aluminum material, but is not limited to aluminum material. Since the wood mounting attachment 323 is made of metal or resin, the processing accuracy of the wood mounting attachment 323 as the indoor side material holding portion can be increased compared to when the glass surface material 35 is made of a wooden indoor side material holding portion, and the deterioration of the wood mounting attachment 323 over time can be suppressed. As a result, it is possible to suppress the glass surface material 35 from easily coming off the lower frame 32. Furthermore, if the wood mounting attachment 323 is made of resin, it is possible to prevent the exterior side of the wooden frame 322 from being cooled from the outside of the room, thereby improving the thermal 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 an opening of the engaged portion 3231. The engaging portion 3212 engages with an 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 toward the indoor side. The lower end of the wood mounting attachment 323 on the indoor side has an L-shaped locking part 3233 whose end that extends toward the indoor side extends downward.

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

[0034] Since the wood mounting attachment 323 can be detachably engaged with the metal frame 321, the wood frame 322 to which the wood mounting attachment 323 is fixed can be detached from and replaced with the metal frame 321. That is, the wood mounting attachment 323 to which the wood 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) having a portion with a shape similar to that of the portion of the wood mounting attachment 323 that engages with the metal frame 321 and another portion with a shape different from that of the wood mounting attachment 323 can be detachably attached to the metal frame 321. The above-mentioned other wood mounting attachment 323 and other wood mounting attachment are prepared in advance by fixing an interior side member made of a non-metallic material different from that of the wood frame 322, such as resin or stone. This allows the use of 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 the indoor components even during renovations, etc. In particular, when the indoor components made of the non-metallic material described above are 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 and the other wood mounting attachment 323 are the same, so that it is possible to suppress the increase in capital investment for manufacturing the product 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-oriented 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 inner sash 4, when the upper frame 41 is assembled to the upper end of the inner meeting frame 44, or when the lower frame 42 is assembled to the lower end of the inner meeting frame 44, a part of the horizontal end of the upper frame 41 (metal frame material 411, wooden frame material 412) or a 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 meeting 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 configured symmetrically. The wooden frame 332 and the wooden frame 432 are configured symmetrically. The wood mounting attachment 333 and the wood mounting attachment 433 are configured symmetrically. For this reason, in the following explanation, the metal frame 331, the wooden frame 332, and the wood mounting attachment 333 will be explained, and explanations of the metal frame 431, the wooden frame 432, and the wood mounting attachment 433 will be omitted.

[0038] As shown in Fig. 3, the indoor side end of the metal frame 331 has an L-shaped engagement part 3311, the end of which extends toward the indoor side and the outside. The vicinity of the indoor side end of the metal frame 331 has an engagement part 3312 that extends toward the indoor side.

[0039] The wood mounting attachment 333 is made of, for example, metal or resin. When it is made of metal, it is made of, for example, aluminum material, but is not limited to, aluminum material. Since the wood mounting attachment 333 is made of metal or resin, the processing precision of the wood mounting attachment 333 as the interior side material holding part can be increased and the deterioration of the wood mounting attachment 333 over time can be suppressed compared to when the glass panel 35 is made of a wooden interior side material holding part. As a result, it is possible to prevent the glass panel 35 from easily coming off the vertical frame 33. Furthermore, when the wood mounting attachment 333 is made of resin, it is possible to prevent the exterior side of the wooden frame 332 from being cooled from the outside of the room, and it is possible to improve the insulation.

[0040] The outside end of the wood mounting attachment 333 on the door-front side has an L-shaped engaged part 3331 whose end extending toward the tail end extends toward the room side. The outside end of the wood mounting attachment 333, midway between the door-front and tail end ends, has an L-shaped engaged part 3332 whose end extending toward the door-front side 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-front side has an L-shaped locking part 3333 whose end extends toward the indoor side and toward the door tail side. The end of the wood mounting attachment 333 on the indoor side of the door tail side has a step part 3334 that protrudes one step toward the indoor side.

[0043] The wooden frame 332 is made of a plank of wood. The outside end of the wooden frame 332 has a latched portion 3321 shaped similarly to the latching portion 3333 with which the latching portion 3333 can be latched. The inside end of the wooden frame 332 has a step 3322 shaped similarly to the step 3334 with which the step 3334 can be latched. 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 aligned with the end of the grating channel 352 on the end of the shoji screen 3.

[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 into the wooden frame 332.

[0045] Since the wood mounting attachment 333 can be detachably engaged with the metal frame 331, the wood 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 wood 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 with a shape similar to that of the portion of the wood mounting attachment 333 that engages with the metal frame 331 and another portion with a shape different from that of the wood mounting attachment 333 can be detachably attached to the metal frame 331. The above-mentioned other wood mounting attachment 333 and other wood mounting attachment are prepared in advance by fixing an interior side member made of a non-metallic material different from that of the wooden frame 332, such as resin or stone. This allows the use of wooden or resin indoor components 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 the indoor components even during renovations. In particular, when the indoor components made of the non-metallic material described above are 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 and the other wood mounting attachment 333 are the same, so that it is possible to suppress the increase in capital investment for manufacturing the product and the increase in costs due to the increase in the number of parts.

[0046] As shown in Fig. 3, the end of the metal frame material 341 of the exterior fitting frame 34 on the indoor side has a U-shaped engagement part 3411 that opens toward the door end side of the shoji screen 3. Both ends of the opening of the engagement part 3411 are formed in a groove shape.

[0047] The wood mounting attachment 343 is made of, for example, metal or resin. When it is made of metal, it is made of, for example, aluminum material, but is not limited to, aluminum material. Since the wood mounting attachment 343 is made of metal or resin, the processing precision of the wood mounting attachment 343 as the interior side material holding part can be increased and the deterioration of the wood mounting attachment 343 over time can be suppressed compared to when the glass panel 35 is made of a wooden interior side material holding part. As a result, it is possible to prevent the glass panel 35 from easily coming off the exterior fitting frame 34. Furthermore, when the wood mounting attachment 343 is made of resin, it is possible to prevent the exterior side of the wooden frame 342 from being cooled from the outside of the room, and it is possible to improve the 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, the wood mounting attachment 343 is fixed to the wooden frame 342 by a screw 344 passing through a through hole formed in the tail end side 3431 and screwing into the wooden frame 342. The wooden frame 342 is made of a wooden plate.

[0049] Since the wood mounting attachment 343 can be detachably engaged with the metal frame 341, the wood 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 wood 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 with a shape similar to that of the portion of the wood mounting attachment 343 that engages with the metal frame 341 and another portion with a shape different from that of the wood mounting attachment 343 can be detachably attached to the metal frame 341. The above-mentioned other wood mounting attachment 343 and other wood mounting attachment are prepared in advance by fixing an interior side member made of a non-metallic material different from that of the wooden frame 342, such as resin or stone. 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 the indoor components even during renovations. In particular, when the indoor components made of the non-metallic material described above are 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 and the other wood mounting attachment 343 are the same, so that it is possible to suppress 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 Fig. 3, the outside end of the metal frame material 441 of the interior meeting frame 44 has an engagement part 4411 that extends toward the outside and the door tip of the shoji screen 4. The inside end of the metal frame material 441 of the interior meeting 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. When it is made of metal, it is made of, for example, aluminum material, but is not limited to, aluminum material. Since the wood mounting attachment 443 is made of metal or resin, the processing precision of the wood mounting attachment 443 as the interior side material holding part can be increased and the deterioration of the wood mounting attachment 443 over time can be suppressed compared to when the glass panel 45 is made of a wooden interior side material holding part. As a result, it is possible to prevent the glass panel 45 from easily coming off the interior joining frame 44. In addition, when the wood mounting attachment 443 is made of resin, it is possible to prevent the exterior side of the wooden frame 442 from being cooled from the outside of the room, and it is possible to improve the 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 an end portion extending toward the shoji 4's leading edge extending toward the room side and 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 4 at the room 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, is formed in a U-shape opening toward the leading edge of the shoji 4, and engages with the engaging portion 4412. The step portion 4434 protrudes one step toward the room side. The locking portion 4435 is formed by an end portion extending from the trailing edge end of the shoji 4 on the outside of the wood mounting attachment 443 to the room side. The locking portion 4436 is formed by an end portion extending further toward the outside of the room from the end portion of the shoji screen 4 on the indoor side of the wood mounting attachment 443 on the door trailing edge side.

[0054] The wooden frame 442 is made of a plank of wood. The outdoor end of the wooden frame 442 has a step 4421 of a similar shape to the step 4434, with which the step 4434 can engage. When a screw 444 that passes through a through hole in the step 4434 is screwed 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, which is the end side of the shoji screen 4, has an engaged part 4451 with a shape similar to that of the engaging part 4435, with which the engaging part 4435 can engage. The end of the wooden frame 445 on the inside of the room, which is the end side of the shoji screen 4, has an engaged part 4452 with a shape similar to that of the engaging part 4436, with which the engaging part 4436 can engage. With the engaged part 4451 engaged with the engaging part 4435 and the engaged part 4452 engaged with the engaging part 4436, the wooden frame 445 is fixed to the projected surface of the wood mounting attachment 443 and covers the projected surface.

[0056] The wooden frame 442 covers the visible surface of the interior joining frame 44 by covering the indoor side 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 that the wooden frame 442 and the wooden frame 445 can be constructed from members independent of each other. 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 332A and wooden frame 432A of the vertical frame 33A and vertical frame 43A are different from the configurations of the wooden frame 332 and wooden frame 432 in the first embodiment. Since the configuration other than this is the same as in the first embodiment, the same members are given the same reference numerals and the description will be omitted.

[0058] The wooden frame 332A is fixed to the wood mounting attachment 333A only by the screw 334A. Therefore, the wooden frame 332A does not have the locked portion 3321 of the wooden frame 332 in the first embodiment. Moreover, 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 the screw 434A. The end of the wooden frame 432A in the left direction of the view (left direction in FIG. 4) is in a positional relationship that coincides 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 frame 332B and wooden frame 432B of the vertical frame 33B and vertical frame 43B are different from the configurations of the wooden frame 332 and wooden frame 432 in the first embodiment. The other configurations are the same as those in the first or second embodiment, so the same members are denoted by the same reference numerals and the description thereof will be omitted.

[0060] The wooden frame 332B is fixed to the joint fitting 3311B that protrudes from the metal frame 331B toward the room side directly by only the screw 334B, without using the wood mounting attachment. The joint fitting 3311B is integrally formed with the metal frame 331B. The joint fitting 3311B does not have to be integrally formed with the metal frame 331B. In this case, the joint fitting and the metal frame may be formed separately. The wooden frame 432B is fixed to the wood mounting attachment 433A by only the screw (not shown). The end of the wooden frame 432B in the left direction of the view (left direction in FIG. 5) is in a positional relationship that 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 frame 332C and wooden frame 432C of the vertical frame 33C and vertical frame 43C are different from the configurations of the wooden frame 332 and wooden frame 432 in the first embodiment. The other configurations are the same as those in the first to third embodiments, so the same members are denoted by the same reference numerals and the description thereof will be omitted.

[0062] The wooden frame 332C is fixed to the joint metal fitting 3311B that protrudes from the metal frame 331B to the indoor side only by the screw 334C, without using a wood mounting attachment. A recess 3365C is formed in the end face of the wooden frame 332C on the indoor side, and a recessed part 336C is fixed in the recess 3365C.

[0063] The wooden frame 432C is fixed to the wood mounting attachment 433A only by screws (not shown). A recess 4325C is formed in the end surface of the wooden frame 432C facing the room, and a recessed part 436C is fixed in the recess 4325C. The end of the wooden frame 432C in the left direction of the view (left direction in FIG. 6) is in a positional relationship that coincides with the end of the 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 joint frame 44D is different from the configuration of the inner joint frame 44 in the first embodiment. Since the other configurations are the same as those in the first to third embodiments, the same members are denoted by the same reference numerals and the description thereof will be omitted.

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

[0066] Both ends of the wooden frame 442D in the left and right directions in the forward direction have a protrusion 4421D and a protrusion 4422D that protrude toward the outside of the room. The end of the wooden frame 445D on the indoor side of the forward direction has a protrusion 4451D. The protrusion 4451D fits with the protrusion 4421D. The end of the wooden frame 446D on the indoor side of the forward direction has a protrusion 4461D. The protrusion 4461D fits with the protrusion 4422D. Since the protrusion 4451D fits with the protrusion 4421D and the protrusion 4461D fits with the protrusion 4422D in this way, even if some variation occurs in the dimensions of the wooden frame 442D, the wooden frame 445D, and the wooden frame 446D, it is possible to make it difficult for the gaps between these members to be exposed. In addition, when the inner fitting frame 44D is grasped and operated to open or close the screen, it is possible to prevent the wooden frame material 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 joint frame 44E is different from the configuration of the inner joint frame 44D in the fifth embodiment. Since the other configurations are the same as those in the fifth embodiment, the same members are given the same reference numerals and the description is omitted.

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

[0069] Next, the 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. Since the other configurations are the same as those in the first embodiment, the same members are given the same reference numerals and the description is omitted.

[0070] The upper frame 31F and the upper frame 41F have the same configuration. Therefore, the upper frame 31F will be described, and the description of the upper frame 41F will be omitted. The lower frame 32F and the lower frame 42F have the same configuration. Therefore, the lower frame 32F will be described, and the description of the lower frame 42F will be omitted.

[0071] The wooden frame 312F is fixed to the wood mounting attachment 313F only by the screw 314F. Therefore, the wooden frame 312F does not have the locked portion 3121 of the wooden frame 312 in the first embodiment. Moreover, 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 arranged at the upper end of the face plate 35. This allows the wooden frame 312F to cover the grating channel 352, thereby improving the design.

[0072] Similarly, the wooden frame 322F is fixed to the wood mounting attachment 323F only by the screw 324F. Therefore, the wooden frame 322F does not have the locked portion 3221 of the wooden frame 322 in the first embodiment. Moreover, 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 has a positional relationship that coincides with the upper end of the grating channel 352 arranged at the lower end of the face member 35. As a result, the wooden frame 322F covers the grating channel 352, thereby improving 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 the configuration is not limited to this. 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 mounting attachment using double-sided tape or adhesive. In addition, when the interior side member is made of resin, the wood mounting attachment may be made of resin and molded integrally with the interior side member. [Explanation of symbols]
