[0008] The first and second structural examples of the first embodiment of this disclosure will be described in detail below with reference to the drawings. As shown in Figure 1, the remodeled joinery 1 of this embodiment is installed in an opening 11 of a building 100 such as an apartment building. Figure 1 shows the remodeled joinery 1 as seen from the interior side. The remodeled joinery 1 is formed by modifying an existing frame 2 that has already been installed by attaching a new frame 3.

[0009] In this specification, "face direction" means the direction of the surface material of the shoji screen 12 in the remodeled joinery 1 fitted into the opening 11 formed in the wall of the building 100, and "depth direction" means the thickness direction (i.e., depth direction) of the above-mentioned surface material. The "depth direction" is also the interior-exterior direction. "Face" means the respective faces of the remodeled joinery 1 that face the exterior and interior sides, and "depth surface" means the face of the remodeled joinery 1 that extends in the interior-exterior direction. In the drawings, the exterior side of the depth direction of the remodeled joinery 1 is denoted as the exterior side X1, and the interior side of the depth direction of the remodeled joinery 1 is denoted as the interior side X2. The horizontal direction in the face direction of the remodeled joinery 1 is denoted as the left-right direction.

[0010] As shown in Figure 1, the remodeled joinery 1 is constructed by attaching a new frame 3 to the inner circumference of an existing frame 2 installed in an opening 11 of the building 100 via an attachment 4 (see Figure 2). The remodeled joinery 1 comprises the existing frame 2, the new frame 3, and the attachment 4 (see Figure 2). Inside the new frame 3, sliding doors 12, 12 are housed so that they can be opened and closed.

[0011] The existing frame 2 is a frame that is installed in the opening 11, either integrally with or separately from the window frame 10. The existing frame 2 is formed in a rectangular frame shape. The existing frame 2 is made of aluminum, aluminum-resin composite, or resin profiles. The existing frame 2 has an existing upper frame 21, an existing lower frame 22, and a pair of existing vertical frames 23 on the left and right.

[0012] The existing upper frame 21 is a long member that extends horizontally above the opening 11. The existing lower frame 22 is a long member that extends horizontally below the opening 11. The pair of existing vertical frames 23 are long members that extend vertically at both ends of the opening 11 in the horizontal direction.

[0013] The new frame 3 is positioned on the inner circumference side of the existing frame 2 via an attachment 4 (see Figure 2). The new frame 3 is formed in a rectangular frame shape. The new frame 3 is made of aluminum profiles. The new frame 3 has a new upper frame 31, a new lower frame 32, and a pair of new vertical frames 33 on the left and right.

[0014] The newly installed upper frame 31 is a long member that extends horizontally above the opening 11. The newly installed lower frame 32 is a long member that extends horizontally below the opening 11. The pair of newly installed vertical frames 33 are long members that extend vertically at both ends of the opening 11 in the horizontal direction.

[0015] As shown in Figure 2, the attachment 4 is positioned between the existing frame 2 and the new frame 3 and is a component for fixing the new frame 3 to the existing frame 2. The attachment 4 has an upper attachment frame 41 (see Figure 2), a lower attachment frame (not shown), and a pair of left and right vertical attachment frames. The upper attachment frame 41, the lower attachment frame, and the pair of left and right vertical attachment frames are each made of, for example, aluminum profiles.

[0016] The attachment upper frame 41, the attachment lower frame, and the pair of left and right attachment vertical frames are arranged along the longitudinal direction of the existing upper frame 21, the existing lower frame 22, and the existing vertical frames 23, respectively. The attachment upper frame 41, the attachment lower frame, and the pair of left and right attachment vertical frames may be arranged in multiple units with intervals between them in the longitudinal direction of the existing upper frame 21, the existing lower frame 22, and the existing vertical frames 23, or they may be composed of a single member extending in the longitudinal direction of the existing upper frame 21, the existing lower frame 22, and the existing vertical frames 23.

[0017] Figure 2 illustrates the fixing structure of the existing upper frame 21, the new upper frame 31, and the attachment upper frame 41 in the first structural example of the first embodiment. In the first structural example of the first embodiment, as shown in Figure 2, the details of a reinforced concrete (RC) structure, such as that found in condominiums and buildings, will be described. In the reinforced concrete (RC) structure shown in Figure 2, the ceiling of the building 100 is configured to have a lower surface that extends in the interior-exterior direction, and a window frame 10 is attached to the lower surface of the ceiling that extends in the interior-exterior direction.

[0018] As shown in FIG. 2, the existing upper frame 21 is attached to the upper side of the opening 11 of the building 100. The existing upper frame 21 includes an indoor-outdoor direction extending plate 211 extending in the indoor-outdoor direction, an outdoor lower protruding plate 212 (outdoor protruding plate) protruding downward from the end of the outdoor side X1 of the indoor-outdoor direction extending plate 211, an indoor lower protruding plate 213 (indoor protruding plate) extending downward from the end of the indoor side X2 of the indoor-outdoor direction extending plate 211, guide rails 214, 215 for the existing shoji erected downward from the middle of the indoor-outdoor direction of the indoor-outdoor direction extending plate 211, an outdoor L-shaped piece 216 protruding upward from the end of the outdoor side X1 of the indoor-outdoor direction extending plate 211, an indoor L-shaped piece 217 protruding upward from the end of the indoor side X2 of the indoor-outdoor direction extending plate 211, and an L-shaped connecting member 25 provided at the end of the indoor side X2. The guide rail 214 is provided on the outdoor side X1, and the guide rail 215 is provided on the indoor side X2.

[0019] The existing upper frame 21 is fixed to the upper edge member 101 of the building 100 through an L-shaped L-shaped connecting member 25 at the end of the indoor side X2 above the opening 11, and is fixed to the building 100 at the outdoor L-shaped piece 216 and the indoor L-shaped piece 217. In this embodiment, a separate L-shaped connecting member 25 is connected to the end of the indoor side X2 of the existing upper frame 21, but it is not limited to this. Instead of providing the L-shaped connecting member 25, a rib protruding from the existing upper frame integrally with the existing upper frame 21 may be provided.

[0020] The outdoor lower protruding plate 212 is formed on the outdoor side X1 of the existing upper frame 21 and protrudes downward in the vertical direction (inside the finding direction). The indoor lower protruding plate 213 is formed on the indoor side X2 of the existing upper frame 21 and protrudes downward in the vertical direction (inside the finding direction).

[0021] The attachment upper frame 41 connects the existing upper frame 21 and the newly installed upper frame 31. As shown in FIG. 2, the attachment upper frame 41 is disposed between the existing upper frame 21 and the newly installed upper frame 31 above the opening 11. The attachment upper frame 41 has a base attachment 40 and an outdoor-side attachment 50 that is separately configured from the base attachment 40. In the present embodiment, the attachment upper frame 41 has a split structure in which the base attachment 40 and the outdoor-side attachment 50 are each separately configured.

[0022] The base attachment 40 extends in the indoor-outdoor direction. The base attachment 40 has an indoor-outdoor direction extending plate 411 that extends in the indoor-outdoor direction, a protruding piece 412 that is formed near the end on the outdoor side X1 in the indoor-outdoor direction of the indoor-outdoor direction extending plate 411 and protrudes upward, and an indoor-side end extending portion 413 (indoor-side extending portion) that is disposed at the end on the indoor side X2.

[0023] The indoor-outdoor direction extending plate 411 is fixed to the indoor-outdoor direction extending plate 211 of the existing upper frame 21 and the building 100 by screws 111 in the middle of the indoor-outdoor direction.

[0024] On the upper surface of the indoor-outdoor direction extending plate 411, the lower end 212a (tip portion) of the outdoor-side lower protruding plate 212 of the existing upper frame 21 abuts on the outdoor side X1, and the lower end 213a (tip portion) of the indoor-side lower protruding plate 213 of the existing upper frame 21 abuts on the indoor side X2.

[0025] The indoor-outdoor direction extending plate 411 has a stepped portion 414 disposed on the end side of the outdoor side X1. The stepped portion 414 has an upper stepped plate portion 415, a lower stepped plate portion 417, and a step 416. The upper stepped plate portion 415 is formed in a plate shape that extends in the indoor-outdoor direction at the end of the outdoor side X1. The lower stepped plate portion 417 is connected to the indoor side X2 of the upper stepped plate portion 415 via the step 416 and is formed in a plate shape that extends in the indoor-outdoor direction below the upper stepped plate portion 415.

[0026] The lengths of the lower ends 214a and 215a of the guide rails 214 and 215 of the existing upper frame 21 are set to a length within a predetermined range so that, on the upper surface of the indoor-outdoor extending plate 411, the lower end 212a (tip) of the outdoor downward projection plate 212 of the existing upper frame 21 does not fail to contact the outdoor side X1, and the lower end 213a (tip) of the indoor downward projection plate 213 of the existing upper frame 21 does not fail to contact the indoor side X2.

[0027] The lower ends 214a and 215a of the guide rails 214 and 215 of the existing upper frame 21 may be formed to a length that abuts against the upper surface of the indoor-outdoor extending plate 411, or they may be formed to a length that abuts against the upper surface of the indoor-outdoor extending plate 411. In this embodiment, the lower end 214a of the guide rail 214 of the existing upper frame 21 is set to a length that abuts against the upper surface of the indoor-outdoor extending plate 411. The lower end 215a of the guide rail 215 of the existing upper frame 21 is set to a length that does not abut against the upper surface of the indoor-outdoor extending plate 411, but is instead separated upward from the upper surface of the indoor-outdoor extending plate 411.

[0028] The protruding piece 412 is formed in an L-shape that opens to the outdoor side X1 and downward. The tip of the protruding piece 412 is positioned along the indoor side X2 of the outdoor side downward protruding plate 212 of the existing upper frame 21.

[0029] The outdoor attachment 50 is fixed to the outdoor end X1 of the indoor-outdoor extending plate 411 of the base attachment 40. The outdoor attachment 50 has an indoor-outdoor extending plate 511 formed at the end of the indoor side X2 and extending in the indoor-outdoor direction, an airtight material mounting projection 512 projecting upward from the outdoor end X1 of the indoor-outdoor extending plate 511, and an L-shaped cover portion 513 (outdoor portion) positioned on the outdoor side X1 at the lower end of the airtight material mounting projection 512. The L-shaped cover portion 513 is positioned further out on the outdoor side X1 than the base attachment 40.

[0030] The indoor-outdoor extending plate 511 is positioned along the lower surface of the upper plate portion 415 of the stepped portion 414 located on the outdoor side X1 end of the indoor-outdoor extending plate 411 of the base attachment 40. When attaching the outdoor attachment 50 to the base attachment 40, the outdoor attachment 50 is moved in the indoor-outdoor direction from the outdoor side X1 toward the base attachment 40, thereby moving the indoor-outdoor extending plate 511 of the outdoor attachment 50 along the lower surface of the upper plate portion 415 of the stepped portion 414 on the outdoor side X1 end of the indoor-outdoor extending plate 411 of the base attachment 40 from the outdoor side X1 toward the indoor side X2, and the outdoor attachment 50 can be engaged with the base attachment 40 and attached. The indoor-outdoor extending plate 511 is fixed to the outdoor side X1 end portion of the indoor-outdoor extending plate 411 of the base attachment 40 by screws 112.

[0031] The airtight seal mounting projection 512 is positioned opposite the outdoor side X1 surface of the outdoor side downward projection plate 212 of the existing upper frame 21. An airtight seal 514 is attached to the airtight seal mounting projection 512. The airtight seal 514 is positioned between the airtight seal mounting projection 512 and the outdoor side X1 surface of the outdoor side downward projection plate 212 of the existing upper frame 21.

[0032] The L-shaped cover portion 513 is positioned at the outer end X1 of the outdoor attachment 50. The L-shaped cover portion 513 is positioned to protrude further outward X1 than the existing upper frame 21 and is formed in an L-shape that opens towards the indoor side X2 and downward. The L-shaped cover portion 513 is positioned on the outer end X1 of the new upper frame 31. The L-shaped cover portion 513 is positioned to cover at least a portion of the outer end X1 of the new upper frame 31.

[0033] As shown in Figure 2, the newly installed upper frame 31 is attached to the inner circumference side (below the attachment upper frame 41) of the attachment upper frame 41 via a spacer member 611. The newly installed upper frame 31 is positioned on the lower surface of the spacer member 611, with the plate-shaped spacer member 611 sandwiched between it and the lower surface of the indoor-outdoor extending plate 411 of the attachment upper frame 41.

[0034] The newly installed upper frame 31 includes a hollow section 311 on the outdoor side of the newly installed upper frame, a hollow section 312 on the indoor side of the newly installed upper frame, a horizontal gutter structure 313, a vertically extending plate section 314 on the outdoor side, an open section 317 on the outdoor side, and guide rails 315 and 316.

[0035] The newly installed upper frame outdoor hollow section 311 and the newly installed upper frame indoor hollow section 312 are both formed as elongated rectangular hollow sections extending in the indoor-outdoor direction and are arranged side by side in the indoor-outdoor direction. The newly installed upper frame outdoor hollow section 311 is located on the outdoor side X1, and the newly installed upper frame indoor hollow section 312 is located on the indoor side X2. A water-sealing packing 311a is attached to the upper surface of the new upper frame outdoor hollow section 311 on the outdoor side X1. The water-sealing packing 311a protrudes upward from the upper surface of the new upper frame outdoor hollow section 311 on the outdoor side X1. The water-sealing packing 311a is formed to extend to a position close to or in contact with the lower surface of the indoor-outdoor extending plate 511 (described later) of the outdoor attachment 50, preventing water from flowing to the indoor side X2.

[0036] The newly installed hollow section 311 on the outdoor side of the upper frame is fixed to the indoor-outdoor extending plate 411 and spacer member 611 of the base attachment 40 by screws 113. The newly installed hollow section 312 on the indoor side of the upper frame is fixed to the indoor-outdoor extending plate 411 and spacer member 611 of the base attachment 40 by screws 114.

[0037] Guide rails 315 and 316 are erected downwards from the newly installed hollow section 311 on the outdoor side of the upper frame and the newly installed hollow section 312 on the indoor side of the upper frame. Guide rails 315 and 316 guide the upper part of the sashes 12, 12 (see Figure 1). Guide rail 315 is installed on the outdoor side X1, and guide rail 316 is installed on the indoor side X2.

[0038] Between guide rail 315 and guide rail 316, a resin cover material 320 is attached to the lower surfaces of the newly installed upper frame outdoor side hollow section 311 and the newly installed upper frame indoor side hollow section 312 so as to cover the exposed aluminum portions of the newly installed upper frame outdoor side hollow section 311 and the newly installed upper frame indoor side hollow section 312. The resin cover material 320 is a cover that covers the space between the rails between guide rail 315 and guide rail 316 on the lower surfaces of the newly installed upper frame outdoor side hollow section 311 and the newly installed upper frame indoor side hollow section 312.

[0039] The horizontal gutter structure 313 is formed on the outdoor side X1 of the newly installed upper frame outdoor side hollow section 311. The horizontal gutter structure 313 is formed in a concave shape that is recessed downwards, so that it is open upwards. As a result, the horizontal gutter structure 313 can store and drain water, and thus functions as a gutter. Water that enters the horizontal gutter structure 313 flows to both ends in the longitudinal direction of the newly installed upper frame 31. As a result, drainage performance can be improved by providing the horizontal gutter structure 313.

[0040] The outdoor vertically extending plate portion 314 is formed in a plate shape that extends downward from the outdoor side end X1 of the horizontal gutter structure portion 313.

[0041] The outdoor opening 317 is formed at the outdoor end X1 of the newly installed upper frame 31, opening towards the outdoor side X1. An airtight material placement member 318 is attached to the outdoor opening 317. An airtight material 319 is attached to the outdoor side X1 of the airtight material placement member 318. The airtight material 319 is positioned between the outdoor side X1 surface of the outdoor end X1 of the newly installed upper frame 31 and the indoor side X2 surface of the protruding plate 513a that protrudes downward (inward in the visible direction) of the L-shaped cover portion 513 of the outdoor attachment 50. As a result, on the outdoor side X1, the airtight material 319 is positioned between the L-shaped cover portion 513 of the outdoor attachment 50 and the newly installed upper frame 31.

[0042] A resin angle member 612 is attached to the lower part of the indoor side X2 of the newly installed upper frame 31. An indoor decorative cover 613 of the upper frame is attached to the resin angle member 612. The indoor decorative cover 613 of the upper frame is formed in an L shape with the outdoor side X1 and the upper side open, and is positioned to cover the end side of the indoor side X2 of the attachment upper frame 41 and the end side of the indoor side X2 of the newly installed upper frame 31.

[0043] Next, a second structural example of the first embodiment will be described with reference to Figure 3. In the second structural example, components identical or equivalent to those in the first structural example will be denoted by the same reference numerals. In addition, in the second structural example, explanations that overlap with those in the first structural example will be omitted as appropriate.

[0044] In the second structural example of the first embodiment, as shown in Figure 3, the details of an ALC structure using lightweight aerated concrete will be described. In the details of the ALC structure using lightweight aerated concrete shown in Figure 3, the lower surface of the ceiling of the building 100A and the side surface extending upward from the exterior end of the lower surface of the ceiling are configured to have right-angle surfaces, and the window frame 10A is attached to the right-angle surface.

[0045] The second structural example differs from the first structural example mainly in the shape of the outdoor attachment 50A and the existing upper frame 21A. The base attachment 40 of the second structural example has the same shape as the base attachment 40 of the first structural example. The outdoor attachment 50A and the existing upper frame 21A will be described in detail.

[0046] The existing upper frame 21A of the second structural example includes an indoor-outdoor extending plate 211A extending in the indoor-outdoor direction, an outdoor downward projecting plate 212 (outdoor projecting plate) extending downward from the outdoor end X1 of the indoor-outdoor extending plate 211, an indoor downward projecting plate 213 (indoor projecting plate) extending downward from the indoor end X2 of the indoor-outdoor extending plate 211, guide rails 214 and 215 for existing sashes erected downward from the middle of the indoor-outdoor extending plate 211 in the indoor-outdoor direction, an outdoor L-shaped piece 216 projecting upward from the outdoor end X1 of the indoor-outdoor extending plate 211, an indoor L-shaped piece 217 projecting upward from the indoor end X2 of the indoor-outdoor extending plate 211, and an outdoor existing upper frame upward extension frame 218 connected to the upper end of the outdoor L-shaped piece 216.

[0047] The exterior existing upper frame extension frame 218 extends upward along the side surface of the right-angled surface of the ceiling of the building 100. The exterior existing upper frame extension frame 218 has a vertically extending portion 218a that extends upward for a predetermined length from the exterior side X1 end of the exterior L-shaped piece 216, an interior-exterior extending portion 218b that extends for a predetermined length from the upper end of the vertically extending portion 218a toward the interior side X2, and an upper end projection portion 218c that protrudes upward for a predetermined length from the interior-exterior extending portion 218b toward the interior side X2.

[0048] The outdoor attachment 50A includes an indoor-outdoor extending plate 511 that extends in the indoor-outdoor direction, an airtight material mounting projection 512 that protrudes upward from the outdoor side X1 end of the indoor-outdoor extending plate 511, an L-shaped cover portion 513 positioned on the outdoor side X1 at the lower end of the airtight material mounting projection 512, and an outdoor attachment upward extension frame 515 connected to the upper end of the L-shaped cover portion 513.

[0049] The outdoor attachment upper extension frame 515 has a vertically extending plate 515a that extends upward from the upper end of the L-shaped cover portion 513, and a plurality of protruding plates 515b that project outwards from the indoor side X2 surface of the vertically extending plate 515a.

[0050] When attaching the outdoor attachment 50A to the base attachment 40, similar to the first structural example, the outdoor attachment 50A is moved in the indoor-outdoor direction from the outdoor side X1 toward the base attachment 40. This moves the indoor-outdoor extending plate 511 of the outdoor attachment 50A along the lower surface of the upper plate portion 415 of the stepped portion 414 on the outdoor side X1 end of the indoor-outdoor extending plate 411 of the base attachment 40 from the outdoor side X1 toward the indoor side X2, thereby engaging and attaching the outdoor attachment 50A to the base attachment 40.

[0051] According to this embodiment, the following effects are achieved. In the first structural example of the first embodiment, the remodeled joinery 1 is configured with a divided structure comprising a base attachment 40 and an exterior attachment 50. In the second structural example of the first embodiment, the remodeled joinery 1A is configured with a divided structure comprising a base attachment 40 and an exterior attachment 50A.

[0052] Therefore, in the first and second structural examples of the first embodiment, while the base attachment 40 is formed in the same shape, the outdoor attachments 50 and 50A can be configured in shapes that accommodate various installations (reinforced concrete (RC) structures used in condominiums and buildings, and ALC structures using lightweight aerated concrete). This makes it possible to standardize the base attachment 40 by forming it in a simple shape, while varying the shapes of the outdoor attachments 50 and 50A, thereby enabling the attachment upper frame 41 to accommodate various installations (reinforced concrete (RC) structures used in condominiums and buildings, and ALC structures using lightweight aerated concrete).

[0053] Furthermore, in the first and second structural examples of the first embodiment, the base attachment 40 abuts against the tip 212a of the outdoor downward projection plate 212 formed on the outdoor side X1 of the existing upper frame 21 and projecting downward (inward in the visible direction), and abuts against the tip 213a of the indoor downward projection plate 213 formed on the indoor side X2 of the existing upper frame 21 and projecting downward (inward in the visible direction).

[0054] As a result, the base attachment 40 is formed in a simple shape that allows it to contact the tip 212a of the outdoor downward projection plate 212 on the outdoor side X1, and to contact the tip 213a of the indoor downward projection plate 213 on the indoor side X2, without forming it in a complex shape. Therefore, by forming the base attachment 40 in a simple shape, it is easy to standardize it as a base component for the attachment upper frame 41.

[0055] Furthermore, in the first and second structural examples of the first embodiment, an airtight material 319 is placed between the L-shaped cover portion 513 and the newly installed upper frame 31. This ensures airtightness between the outdoor attachment 50 and the newly installed upper frame 31.

[0056] Next, the third and fourth structural examples of the first embodiment will be described with reference to Figures 4 and 5. Compared to the first and second structural examples, the third and fourth structural examples of the first embodiment differ in that, when the outdoor attachments 50x and 50Ax are attached to the base attachment 40A, the direction in which the outdoor attachments 50x and 50Ax engage with the base attachment 40A is different.

[0057] A third structural example will now be described. The third structural example is a modified version of the first structural example, and as shown in Figure 4, the attachment upper frame 41x (attachment) comprises a base attachment 40A and an outdoor attachment 50x. In the description of the third structural example, the same configuration as in the first structural example will be omitted.

[0058] The base attachment 40A has an indoor-outdoor extending plate 411A instead of the indoor-outdoor extending plate 411 of the first structural example of the first embodiment. The indoor-outdoor extending plate 411A has a stepped portion 414A positioned on the end side of the outdoor side X1, and a downward projecting projection 418 that protrudes downward from the end of the outdoor side X1 of the upper plate portion 415a of the stepped portion 414A. The upper plate portion 415a of the stepped portion 414A is formed to have a shorter length on the outdoor side X1 than the upper plate portion 415 of the stepped portion 414 of the first embodiment. A downward-opening recess 419 is formed between the step 416 of the stepped portion 414A and the downward projecting projection 418, opening downward.

[0059] The outdoor attachment 50x has an indoor-outdoor extending plate 511A instead of the indoor-outdoor extending plate 511 of the first structural example of the first embodiment. The indoor-outdoor extending plate 511A has a stepped portion 518 formed in a stepped shape and an upwardly protruding projection 519. The stepped portion 518 has an upper plate portion 518a, a lower plate portion 518c, and a step 518b.

[0060] The upper plate portion 518a is formed as a plate that extends in the indoor-outdoor direction at the end of the indoor-side X2. The upper plate portion 518a is positioned in the downward open recess 419 of the indoor-outdoor extending plate 411A of the base attachment 40A.

[0061] The lower plate portion 518c is connected to the outdoor side X1 of the upper plate portion 518a via a step 518b, and is formed as a plate extending in the indoor-outdoor direction below the upper plate portion 518a.

[0062] The upward projecting projection 519 protrudes upward from the upper surface of the lower plate portion 518c on the outdoor side X1 of the step 518b. An upward-opening recess 520 is formed between the step 518b and the upward projecting projection 519, opening upward. A downward projecting projection 418, formed at the outdoor side X1 end of the indoor-outdoor extending plate 411A of the base attachment 40A, is positioned in the upward-opening recess 520.

[0063] When attaching the outdoor attachment 50x to the base attachment 40A, the outdoor attachment 50x is moved from the bottom to the top toward the base attachment 40A, thereby engaging the upper plate portion 518a of the stepped portion 518 of the outdoor attachment 50x with the downward open recess 419 of the base attachment 40A, and engaging the downward protruding projection 418 on the outdoor side X1 of the indoor-outdoor extending plate 411A of the base attachment 40A with the upward open recess 520 of the outdoor attachment 50x, thereby attaching the outdoor attachment 50x to the base attachment 40A.

[0064] As described above, in the first structural example and the third structural example of the first embodiment, in the first structural example shown in Figure 2, the outdoor attachment 50 is moved in the indoor-outdoor direction to engage with the base attachment 40 and attach it, whereas in the third structural example shown in Figure 4, the outdoor attachment 50x is moved in the vertical direction (visible direction) to engage with the base attachment 40A and attach it. Therefore, in the first structural example and the third structural example of the first embodiment, the direction in which the outdoor attachments 50 and 50x are engaged with the base attachments 40 and 40A and attached is different.

[0065] Next, the fourth structural example will be described. The fourth structural example is a modified version of the second structural example, and as shown in Figure 5, the attachment upper frame 41Ax (attachment) comprises a base attachment 40A and an outdoor attachment 50Ax. The fourth structural example is a modified version of the second structural example with the same changes as when the first structural example was transformed into the third structural example. In the description of the fourth structural example, the same configurations as those in the first and third structural examples will not be described.

[0066] In the fourth structural example, as in the third structural example, when attaching the outdoor attachment 50Ax to the base attachment 40A, the outdoor attachment 50Ax is moved from the bottom to the top toward the base attachment 40A, thereby engaging the upper plate portion 518a of the stepped portion 518 of the outdoor attachment 50x with the downward open recess 419 of the base attachment 40A, and engaging the downward protruding projection 418 of the indoor-outdoor extending plate 411A of the base attachment 40A with the upward open recess 520 of the outdoor attachment 50x, thereby attaching the outdoor attachment 50Ax to the base attachment 40A.

[0067] As described above, in the second and fourth structural examples of the first embodiment, in the second structural example shown in Figure 3, the outdoor attachment 50A is moved in the indoor-outdoor direction to engage with the base attachment 40 and attach it, whereas in the fourth structural example shown in Figure 5, the outdoor attachment 50Ax is moved in the vertical direction (visible direction) to engage with the base attachment 40A and attach it. Therefore, in the second and fourth structural examples of the first embodiment, the direction in which the outdoor attachments 50A and 50Ax are engaged with the base attachments 40 and 40A and attached them is different.

[0068] In the fourth structural example shown in Figure 5, a backup material 102 is placed on the outdoor side X1 of the upper end projection 218c of the existing upper frame extension frame 218 on the outdoor side of the existing upper frame 21A. A sealing material 103 is applied to the outdoor side X1 of the backup material 102 to seal the gap between the building 100A and the existing upper frame 21A.

[0069] A fin member 515c is attached to the indoor side X2 surface of the upper end of the outdoor attachment upper extension frame 515. The fin member 515c is made of a soft resin material. The fin member 515c extends upward in a fin shape along the outdoor side X1 surface of the sealing material 103 from between the upper end of the outdoor attachment upper extension frame 515 and the vertically extending portion 218a of the existing outdoor upper frame upper extension frame 218. This allows the fin member 515c to conceal the area where the sealing material 103 is used to seal the building 100A and the existing upper frame 21A. If the sealing material 103 deteriorates over time, the soft resin fin member 515c can be removed or cut to allow for the application of new sealing material 103.

[0070] Next, a second embodiment will be described. In the second embodiment, components that are the same as or equivalent to those in the first structural example of the first embodiment will be denoted by the same reference numerals. In addition, in the second embodiment, explanations that overlap with those in the first structural example of the first embodiment will be omitted as appropriate.

[0071] The second embodiment differs from the first structural example of the first embodiment mainly in the configuration of the outdoor attachment 50B. The base attachment 40 of the second embodiment has the same shape as the base attachment 40 of the first embodiment. The outdoor attachment 50B will be described in detail.

[0072] In the second embodiment, as shown in Figure 6, in the outdoor attachment 50B, an L-shaped cover portion 516 is provided on the outdoor side X1 of the L-shaped cover portion 513 of the outdoor attachment 50 of the first structural example of the first embodiment.

[0073] In the second embodiment, the two L-shaped cover portions 513 and 516 of the outdoor attachment 50B are arranged side by side in the indoor-outdoor direction. The L-shaped cover portion 513 is provided on the indoor side X2, and the L-shaped cover portion 516 is connected to the outdoor side X1 of the L-shaped cover portion 513.

[0074] In other words, the outdoor attachment 50B has an indoor-outdoor extending plate 517 that extends in the indoor-outdoor direction, and two protruding plates 513a and 516a that protrude downward in the vertical direction (inward in the visible direction) from the indoor-outdoor extending plate 517 and are spaced apart in the indoor-outdoor direction. The protruding plate 516a is located on the outdoor side X1, and the protruding plate 513a is located on the indoor side X2.

[0075] On the base end side of the protruding plate 513a of the two protruding plates 513a and 516a, a cut groove 513b (cuttable portion) is provided at the connection point with the indoor-outdoor extending plate 517, allowing it to be cut from the indoor-outdoor extending plate 517. This allows the protruding plate 513a to be cut at the cut groove 513b or not cut at the cut groove 513b, depending on the difference in the indoor-outdoor length of the new upper frame 31. Thus, it can accommodate differences in the indoor-outdoor length of the new upper frame 31.

[0076] According to the second embodiment, the base attachment 40 is formed in the same shape as the base attachment 40 of the first embodiment, while the outdoor attachment 50B is configured with a cut groove 513b, allowing it to be cut using the cut groove 513b according to the difference in length of the newly installed upper frame 31 in the indoor and outdoor directions. This makes it possible to form the base attachment 40 in a simple and common shape, while varying the shape of the outdoor attachment 50B, thereby enabling the attachment upper frame 41B to accommodate various shapes.

[0077] While a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the embodiment described above and can be modified as appropriate.

[0078] For example, the above embodiment described the case in which the remodeling fixture 1 is applied to a sliding window type remodeling sash. However, it is not limited to this. The remodeling fixture may also be applied to, for example, an opening and closing type remodeling fixture in which the door body rotates around a pivot axis to open and close, or a vertical sliding type remodeling fixture. Alternatively, the remodeling fixture may also be applied to, for example, a fixed type remodeling fixture in which the glass is installed while the fixture is fixed to the frame without opening and closing.

[0079] In the above embodiment, the case in which the attachment is an upper attachment frame was described, but it is not limited to this. The attachment may also be a vertical attachment frame or a lower attachment frame. [Explanation of Symbols]
