Description

[Technical field]

[0001] The present disclosure relates to retrofit fittings. [Background technology]

[0002] Conventionally, a covering method has been adopted for renovating openings in buildings by installing new fixtures in the openings. In the renovated fixtures renovated by this covering method, a new frame is attached to the inner periphery of the existing frame attached to the opening of the building (see, for example, Patent Document 1).

[0003] In the renovation fixture described in Patent Document 1, when a new frame is attached to an existing frame, a support member that supports from below is placed between the existing frame and the new frame. The support member is attached to the existing frame. The new frame is attached to the upper part of the support member attached to the existing frame. The support member has a protruding plate that protrudes toward the existing frame. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2011-12406 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, when attaching a new frame to an existing frame, there are cases where the new frame is attached to the existing frame with an attachment frame attached to the outer periphery of the new frame. In this case, if a protruding portion is formed from the attachment frame toward the existing frame, the protruding portion of the attachment frame gets in the way, making it difficult to attach the new frame to the inner periphery of the existing frame. Therefore, it is required that the new frame can be easily attached to the inner periphery of the existing frame with the attachment frame attached to the outer periphery of the new frame.

[0006] The present disclosure aims to provide a renovation fixture that allows a newly constructed frame to be easily attached to the inner periphery of an existing frame with an attachment frame attached to the outer periphery of the newly constructed frame. [Means for solving the problem]

[0007] The present disclosure relates to a remodeling fixture that is attached to an existing frame provided at an opening in a building, comprising a new frame formed by assembling all four sides, and an attachment frame that is attached to the inner periphery of the existing frame while being attached to the outer periphery of the new frame by assembling all four sides, wherein the attachment frame has a planar outer periphery surface formed on the outer periphery of the attachment frame, facing the existing frame, and extending in an indoor-outdoor direction.

[0019] With the new frame 2, with the attachment frame 3 attached to its outer periphery, attached to the existing frame 6, the new upper frame 21 is attached to the inner periphery of the existing upper frame 61, with the attachment upper frame 31 sandwiched between them, as shown in Fig. 10. The new upper frame 21 has guide rails 211, 212 on the upper side of the shoji screens 10, 10 that are erected facing downward.

[0020] When the new frame 2, with the attachment frame 3 attached to its outer periphery, is attached to the existing frame 6, the new sill 22 is attached to the inner periphery of the existing sill 62, with the attachment sill 32 sandwiched between them, as shown in Fig. 10. The new sill 22 has guide rails 221, 222 on the lower side of the shoji screens 10, 10 that are erected facing upward.

[0021] The new vertical frame 23 is attached to the inner periphery of the existing vertical frame 63, with the attachment vertical frame 33 sandwiched therebetween, as shown in Figure 11, when the new frame 2 with the attachment frame 3 attached to its outer periphery is attached to the existing frame 6.

[0022] The new upper frame 21, the new lower frame 22, and the new vertical frame 23 are formed of, for example, a metal material or a resin material. As shown in Fig. 10 and Fig. 11, resin angle members 213, 223, and 233 are provided on the room side X2 of the new upper frame 21, the new lower frame 22, and the new vertical frame 23, respectively. The resin angle members 213, 223, and 233 are each disposed with a gap between them and the frame member 101.

[0023] The above-mentioned new frame 2 (new upper frame 21, new lower frame 22, and left and right new vertical frames 23) are attached to the inner circumference side of the existing frame 6 (existing upper frame 61, existing lower frame 62, and left and right existing vertical frames 63), with the attachment frame 3 (upper attachment frame 31, lower attachment frame 32, and left and right vertical attachment frames 33) arranged around the outer periphery.

[0024] The attachment frame 3 is attached to the outer periphery of the new frame 2 in a four-way configuration. The attachment frame 3 is attached to the inner periphery of the existing frame 6 in a state in which the attachment frame 3 is attached to the outer periphery of the new frame 2 in a four-way configuration.

[0025] 8 and 9, the attachment frame 3 is configured by arranging an upper attachment frame 31, a lower attachment frame 32, and a pair of vertical attachment frames 33 on all four sides to form a rectangle. The upper attachment frame 31, the lower attachment frame 32, and the left and right vertical attachment frames 33 are each made of, for example, an aluminum material.

[0026] The upper attachment frame 31 is disposed at the top of the attachment frame 3 and extends in the left-right direction (horizontal direction). The lower attachment frame 32 is disposed at the bottom side of the attachment frame 3 and extends in the left-right direction (horizontal direction). The vertical attachment frame 33 is disposed at the end sides in the left-right direction of the attachment frame 3 and extends in the up-down direction.

[0027] As shown in Figure 8, the attachment frame 3 is configured in a so-called vertical overhanging structure, in which the longitudinal ends of the attachment vertical frame 33 are positioned outside the longitudinal ends of the attachment upper frame 31 and the attachment lower frame 32 so as to cover the longitudinal ends of the attachment upper frame 31 and the attachment lower frame 32.

[0028] When the attachment frame 3 is attached to the inner periphery of the existing frame 6, it is disposed between the new frame 2 and the existing frame 6. The upper attachment frame 31 is attached in a state where it is hooked onto the new upper frame 21, as shown in Fig. 12. The lower attachment frame 32 is attached in a state where it is hooked onto the new lower frame 22, as shown in Fig. 13. The vertical attachment frame 33 is attached in a state where it is hooked onto the new vertical frame 23, as shown in Figs. 14 and 15. Note that the attachment frame 3 (upper attachment frame 31, lower attachment frame 32, vertical attachment frame 33) may be fastened by screws or the like without being hooked onto the new frame 2 (new upper frame 21, new lower frame 22, new vertical frame 23).

[0029] 16 and 17, in a state in which the upper attachment frame 31, the lower attachment frame 32, and the pair of vertical attachment frames 33 are attached to the outer periphery of the new frame 2, the upper attachment frame 31, the lower attachment frame 32, and the pair of vertical attachment frames 33 are fixed to each other with screws 34 (fastening members) at the assembly portions of any two frames. Specifically, the upper and lower ends of each of the pair of vertical attachment frames 33 are fixed to both ends in the longitudinal direction of the upper attachment frame 31 with the screws 34, and the upper and lower ends of each of the pair of vertical attachment frames 33 are fixed to both ends in the longitudinal direction of the lower attachment frame 32 with the screws 34.

[0030] As shown in Figure 10, the attachment upper frame 31 has an outdoor indoor / outdoor extending portion 311, an attachment upper frame hollow portion 312 (hollow portion) with an outer peripheral side flat surface 312a formed therein, an outdoor vertical extending plate portion 313 (facing direction extending plate portion), an indoor horizontal extending plate 314 (extending plate), an indoor downward extending portion 315, an indoor lower end horizontal protruding piece 316, and an L-shaped hook piece 317.

[0031] The outdoor side indoor / outdoor direction extending portion 311 and the attachment upper frame hollow portion 312 are arranged side by side in the indoor / outdoor direction. The outdoor side indoor / outdoor direction extending portion 311 is arranged on the outdoor side X1, and the attachment upper frame hollow portion 312 is arranged on the indoor side X2. The outdoor side indoor / outdoor direction extending portion 311 is formed at a position lower than the top surface of the attachment upper frame hollow portion 312.

[0032] The outdoor vertical extending plate portion 313 is formed in a plate shape extending upward from the outdoor side X1 end of the outdoor side indoor / outdoor extending portion 311. The outdoor side vertical extending plate portion 313 is arranged on the outdoor side X1 and extends in the vertical direction (view direction). A pair of engaging protrusions 313a arranged spaced apart above and below are formed on the lower side of the outdoor side X1 surface of the outdoor side vertical extending plate portion 313. A pair of engaging protrusions 55 of the outdoor side decorative cover 51 engage with and are attached to the pair of engaging protrusions 313a.

[0033] As shown in FIG. 18, a gutter structure 310 is formed on the upper part of the attachment upper frame 31. The gutter structure 310 is formed by the upper surface of the outdoor-side indoor-outdoor extending part 311, the outdoor-side X1 surface of the attachment upper frame hollow part 312, and the indoor-side X2 surface of the lower side of the outdoor-side vertical extending plate part 313. The gutter structure 310 is formed on the upper part of the attachment upper frame 31, is formed to be open toward the upper side, and extends in the left-right direction (horizontal direction). Both ends of the gutter structure 310 in the longitudinal direction are formed to be open to the outside in the left-right direction. Water that has entered the gutter structure 310 flows to both ends of the attachment upper frame 31 in the longitudinal direction, passes through the longitudinal ends open to the outside in the left-right direction, passes through the notch part 337 of the attachment vertical frame 33, and flows into the inside of the attachment vertical frame 33.

[0034] As shown in Fig. 10, the attachment upper frame hollow portion 312 is formed in a hollow shape of a long and narrow rectangle extending in the indoor / outdoor direction. An outer periphery side flat surface 312a is formed on the upper surface of the attachment upper frame hollow portion 312. The outer periphery side flat surface 312a is formed on the outer periphery side of the attachment frame 3 in the attachment upper frame 31. The outer periphery side flat surface 312a faces the existing upper frame 61 and is formed in a flat shape extending in the indoor / outdoor direction and the horizontal direction. The outer periphery side flat surface 312a is formed over the entire longitudinal area of ​​the attachment upper frame 31 and faces upward.

[0035] The outer peripheral plane 312a is formed in a flat shape so as not to come into contact with the inner peripheral side of the existing frame 6 when the attachment frame 3 with the new frame 2 attached thereto is attached to the inner peripheral side of the existing frame 6. In this embodiment, as shown in Fig. 12, the outer peripheral side of the attachment upper frame 31 is formed with an L-shaped space S1 as shown by a virtual line (two-dot chain line) from the indoor side X2 toward the outdoor side X1 by the space from the upper side of the outer peripheral plane 312a to the space in front of the outdoor side vertical extension plate portion 313 and the space from the space in front of the outdoor side vertical extension plate portion 313 toward the upper side. The L-shaped space S1 is formed on the outer peripheral side of the attachment upper frame 31 along the indoor side X2 surface of the outdoor side vertical extension plate portion 313 and the outer peripheral plane 312a.

[0036] This allows the existing upper frame 61 to be stored in the L-shaped space S1, making it possible to easily attach the attachment frame 3 with the new frame 2 attached to the existing frame 6. In particular, in this embodiment, as shown in Fig. 10, the outer peripheral side flat surface 312a is formed along the indoor / outdoor direction of the attachment upper frame 31, so that the attachment upper frame 31 with the new upper frame 21 attached can be attached to the existing upper frame 61 in a manner that does not get in the way during attachment in accordance with existing frames 6 of various shapes.

[0037] 10, the indoor side horizontal extension plate 314 extends horizontally on the indoor side X2 from the end of the upper end of the attachment upper frame hollow portion 312 on the indoor side X2. An indoor side flat surface 314a on the outer periphery side of the attachment frame 3 of the indoor side horizontal extension plate 314 is formed on the same plane as the outer periphery side flat surface 312a of the attachment upper frame hollow portion 312. The indoor side flat surface 314a is formed in a planar shape over the entire longitudinal area of ​​the attachment upper frame 31.

[0038] When the attachment frame 3 is fixed to the building 100 (frame), the indoor-side horizontal extension plate 314 is disposed with the screw 36 penetrating therethrough. Thus, the indoor-side horizontal extension plate 314 is fixed to the building 100 (frame) by the screw 36. When a gap is formed between the indoor-side flat surface 314a of the indoor-side horizontal extension plate 314 and the frame member 101, a spacer member 37 is disposed. The spacer member 37 is composed of a plurality of sheets, and the thickness of the sheet for filling the gap is set according to the size of the gap between the indoor-side flat surface 314a of the indoor-side horizontal extension plate 314 and the frame member 101.

[0039] The indoor side downward extension portion 315 extends downward from the lower end of the indoor side X2 end of the attachment upper frame hollow portion 312. The indoor side lower end horizontal protruding piece 316 protrudes from the lower end of the indoor side downward extension portion 315 to the indoor side X2.

[0040] The L-shaped hook piece 317 protrudes downward in an L shape from the outdoor side X1 portion of the undersurface of the outdoor side indoor / outdoor direction extending portion 311. When attaching the attachment upper frame 31 to the new upper frame 21, the L-shaped hook piece 317 is hooked onto the protruding hook piece 214 of the new upper frame 21, as shown in Fig. 12. Note that the structure for fixing the attachment upper frame 31 to the new upper frame 21 may be a structure for fastening with screws or the like, rather than a hooking structure.

[0041] As shown in Figure 10, the attachment lower frame 32 has an indoor / outdoor extending portion 321, an attachment lower frame hollow portion 322 (hollow portion) on which an outer peripheral side plane 322a is formed, an outdoor vertical extending plate portion 323 (facing direction extending plate portion), an indoor side horizontal extending plate 324 (extending plate), an indoor side upward extending portion 325, and an L-shaped hook piece 326.

[0042] The indoor / outdoor direction extending portion 321 and the attachment lower frame hollow portion 322 are arranged side by side in the indoor / outdoor direction. The indoor / outdoor direction extending portion 321 is arranged on the outdoor side X1, and the attachment lower frame hollow portion 322 is arranged on the indoor side X2. The indoor / outdoor direction extending portion 321 is formed at a position lower than the upper surface of the attachment lower frame hollow portion 322.

[0043] The exterior vertical extending plate portion 323 is formed in a plate shape extending downward from the end of the exterior side X1 of the attachment lower frame hollow portion 322. The exterior vertical extending plate portion 323 is arranged on the exterior side X1 and extends in the vertical direction (view direction). A pair of engaging protrusions 323a arranged spaced apart above and below are formed on the upper side of the exterior side X1 surface of the exterior vertical extending plate portion 323. A pair of engaging protrusions 55 of the exterior decorative cover 51 engage with and are attached to the pair of engaging protrusions 323a.

[0044] The attachment lower frame hollow portion 322 is formed in a hollow shape of a long and narrow rectangle extending in the indoor / outdoor direction. An outer peripheral side flat surface 322a is formed on the lower surface of the attachment lower frame hollow portion 322. The outer peripheral side flat surface 322a is formed on the outer peripheral side of the attachment frame 3 in the attachment lower frame 32. The outer peripheral side flat surface 322a faces the existing lower frame 62 and is formed in a flat shape extending in the indoor / outdoor direction and the horizontal direction. The outer peripheral side flat surface 322a is formed over the entire longitudinal area of ​​the attachment lower frame 32 and faces downward.

[0045] The outer peripheral side plane 322a is formed in a flat shape so as not to come into contact with the inner peripheral side of the existing frame 6 when the attachment frame 3 to which the new frame 2 is attached is attached to the inner peripheral side of the existing frame 6. In this embodiment, as shown in Fig. 13, the outer peripheral side of the attachment lower frame 32 is formed with an L-shaped space S2 as shown by a virtual line (two-dot chain line) from the indoor side X2 toward the outdoor side X1 by the space from the lower side of the outer peripheral side plane 322a to the space in front of the outdoor side vertical extension plate portion 323 and the space from the space in front of the outdoor side vertical extension plate portion 323 toward the lower side. The L-shaped space S2 is formed on the outer peripheral side of the attachment lower frame 32 along the indoor side X2 surface of the outdoor side vertical extension plate portion 323 and the outer peripheral side plane 322a.

[0046] As a result, since the existing lower frame 62 can be accommodated in the L-shaped space S2, the attachment frame 3 with the new frame 2 attached can be easily attached to the existing frame 6. In particular, in the present embodiment, as shown in FIG. 10, since the outer peripheral side plane 322a is formed along the indoor-outdoor direction of the attachment lower frame 32, the attachment lower frame 32 with the new lower frame 22 attached can be attached to the existing lower frame 62 so as not to interfere with the attachment to existing frames 6 of various shapes. When attaching the attachment frame 3 with the new frame 2 attached to the existing frame 6, it is attached in a tilted state such that the lower end side is positioned closer to the existing frame 6 side than the upper end side. Therefore, after the existing lower frame 62 enters the L-shaped space S2, the entire attachment frame 3 is attached to the existing frame 6. Therefore, by accommodating the L-shaped space S2 in the existing lower frame 62, the attachment frame 3 with the new frame 2 attached can be easily attached to the existing frame 6.

[0047] As shown in FIG. 10, the indoor side horizontal extension plate 324 extends horizontally in the indoor side X2 direction from the end of the indoor side X2 at the upper end of the attachment lower frame hollow portion 322. The indoor side plane 324a on the outer peripheral side of the attachment frame 3 in the indoor side horizontal extension plate 324 is formed on the same plane as the outer peripheral side plane 322a of the attachment lower frame 32. The indoor side plane 324a is formed in a planar shape over the entire longitudinal direction of the attachment lower frame 32.

[0048] When the attachment frame 3 is fixed to the building 100 (frame), the screws 36 are arranged to penetrate the indoor side horizontal extension plate 324. As a result, the indoor side horizontal extension plate 324 is fixed to the building 100 (frame) by the screws 36. When a gap is formed between the indoor side plane 324a of the indoor side horizontal extension plate 324 and the frame member 101, a spacer member is arranged. The spacer member is composed of a plurality of sheets, and the thickness of the sheet for filling the gap is set according to the size of the gap between the indoor side plane 324a of the indoor side horizontal extension plate 324 and the frame member 101. In the present embodiment, since no gap is formed between the indoor side plane 324a of the indoor side horizontal extension plate 324 and the frame member 101, no spacer member is arranged.

[0049] The indoor side upward extension portion 325 extends upward from the upper end portion of the indoor side X2 end portion of the attachment lower frame hollow portion 322.

[0050] The L-shaped hook piece 326 protrudes upward in an L shape from the outdoor side X1 portion of the upper surface of the indoor / outdoor direction extending portion 321. When attaching the attachment lower frame 32 to the new lower frame 22, the L-shaped hook piece 326 is hooked onto the L-shaped hook piece 224 of the new lower frame 22, as shown in Fig. 13. Note that the structure for fixing the attachment lower frame 32 to the new lower frame 22 may be a structure for fastening with screws or the like, rather than a hooking structure.

[0051] The vertical attachment frame 33 is arranged in a so-called vertically-hung structure, in which the longitudinal ends of the vertical attachment frame 33 are arranged outside the longitudinal ends of the upper attachment frame 31 and the lower attachment frame 32. As shown in Fig. 11, the vertical attachment frame 33 has a vertical attachment frame hollow portion 331 (hollow portion) on which an outer peripheral side flat surface 331a is formed, an exterior left-right direction extending plate portion 332 (finding direction extending plate portion), an interior side indoor direction extending portion 333 (extending plate), an interior side extending portion 334, an interior side end protruding piece 335, and a protruding hook piece 336.

[0052] The vertical attachment frame hollow portion 331 is formed in a hollow shape of a long and narrow rectangle extending in the indoor / outdoor direction. An outer peripheral side plane 331a is formed on the outer surface in the left-right direction of the vertical attachment frame hollow portion 331. The outer peripheral side plane 331a is formed on the outer peripheral side of the attachment frame 3 in the vertical attachment frame 33. The outer peripheral side plane 331a faces the existing vertical frame 63 and is formed in a planar shape extending in the indoor / outdoor direction and the up-down direction. The outer peripheral side plane 331a is formed over the entire longitudinal area of ​​the vertical attachment frame 33 and faces outward in the left-right direction.

[0053] The outer peripheral side plane 331a is formed in a flat shape so as not to come into contact with the inner peripheral side of the existing frame 6 when the attachment frame 3 to which the new frame 2 is attached is attached to the inner peripheral side of the existing frame 6. In this embodiment, as shown in Figs. 14 and 15, an L-shaped space S3 is formed on the outer peripheral side of the attachment vertical frame 33 from the indoor side X2 toward the outdoor side X1, as shown by a virtual line (two-dot chain line) by the outer space in the left-right direction of the outer peripheral side plane 331a and the indoor side space of the outdoor side left-right extending plate portion 332. The L-shaped space S3 is formed on the outer peripheral side of the attachment vertical frame 33 along the indoor side X2 surface of the outdoor side left-right extending plate portion 332 and the outer peripheral side plane 331a.

[0054] As a result, the existing vertical frame 63 can be stored in the L-shaped space S3, and the attachment frame 3 with the new frame 2 attached thereto can be easily attached to the existing frame 6.

[0086] The following describes the procedure for constructing the remodeled fitting 1. When constructing the remodeled fitting 1, first, the attachment frame 3 is attached to the outer periphery of the new frame 2 that has been assembled on all four sides.

[0087] First, as shown in Figure 9, in order to attach the attachment frame to the new frame 2, the upper attachment frame 31, the lower attachment frame 32 and the vertical attachment frame 33 are hooked and positioned on the new upper frame 21, the new lower frame 22 and the new vertical frames 23 on the left and right, respectively.

[0088] Specifically, as shown in FIG. 9, an upper attachment frame 31, a lower attachment frame 32, and a pair of vertical attachment frames 33 are assembled to the outer periphery of the new frame 2, which is constructed by assembling four peripheries (attachment framework mounting process).

[0089] The order of assembling the upper attachment frame 31, the lower attachment frame 32, and the pair of vertical attachment frames 33 is as follows: first, the upper attachment frame 31 is attached to the new upper frame 21, and the lower attachment frame 32 is attached to the new lower frame 22. Thereafter, with the upper attachment frame 31 attached to the new upper frame 21 and the lower attachment frame 32 attached to the new lower frame 22, the pair of vertical attachment frames 33 are attached to the new vertical frames 23.

[0090] In detail, in order to attach the attachment upper frame 31 to the new upper frame 21, as shown in FIG. ToAt a portion closer to the outside X1 in the installation, the L-shaped hook piece 317 of the attachment upper frame 31 is hooked onto the protruding hook piece 214 of the new upper frame 21, and the attachment upper frame 31 is disposed and attached to the outer surface of the new upper frame 21 on the inside X2 of the portion where the L-shaped hook piece 317 of the attachment upper frame 31 is hooked onto the hook piece 214 of the new upper frame 21. As a result, the attachment upper frame 31 is attached in a state of being hooked onto the new upper frame 21.

[0091] 13, in order to attach the attachment lower frame 32 to the new lower frame 22, the L-shaped hook piece 224 of the attachment lower frame 32 is hooked onto the L-shaped hook piece 326 of the new lower frame 22 in a portion closer to the outside room X1 in the indoor / outdoor direction, and the attachment lower frame 32 is disposed and attached to the outer surface of the new lower frame 22 on the inside room side X2 of the portion where the L-shaped hook piece 224 of the attachment lower frame 32 is hooked onto the L-shaped hook piece 326 of the new lower frame 22. In this way, the attachment lower frame 32 is attached in a state where it is hooked onto the new lower frame 22.

[0092] Thereafter, as shown in Fig. 16 and Fig. 17, the attachment upper frame 31 is attached to the new upper frame 21 and the attachment lower frame 32 is attached to the new lower frame 22, and the attachment vertical frame 33 is attached to the new vertical frame 23 as shown in Fig. 14 and Fig. 15. In this case, as shown in Fig. 14 and Fig. 15, the protruding hook piece 336 of the attachment vertical frame 33 is hooked to the L-shaped hook piece 234 of the new vertical frame 23 in the part closer to the outside X1 in the indoor / outdoor direction, and the attachment vertical frame 33 is disposed and attached to the outer surface of the new vertical frame 23 on the indoor side X2 of the part where the protruding hook piece 336 of the attachment vertical frame 33 is hooked to the L-shaped hook piece 234 of the new vertical frame 23. As a result, the attachment vertical frame 33 is attached in a state of being hooked to the new vertical frame 23.

[0093] Next, as shown in FIGS. 16 and 17, the longitudinal ends of the attachment upper frame 31 and the attachment vertical frame 33 are fixed to each other with screws 34, and the longitudinal ends of the attachment lower frame 32 and the attachment vertical frame 33 are fixed to each other with screws 34 (attachment frame fastening step).

[0094] Here, as shown in FIGS. 16 and 17, the upper and lower ends of the attachment vertical frame 33 having a so-called vertical-lap structure are fixed to the end faces of the longitudinal ends of the attachment upper frame 31 with screws 34 from the outer sides in the lateral direction. As a result, in each of the left and right attachment vertical frames 33, the upper end of the attachment vertical frame 33 is fixed to the end face of the longitudinal end of the attachment upper frame 31 with a screw 34, and the lower end of the attachment vertical frame 33 is fixed to the end face of the longitudinal end of the attachment lower frame 32 with a screw 34. In this way, the attachment frame 3 assembled in the four circumferences is attached to the four circumferences of the outer periphery of the new frame 2.

[0095] As described above, the attachment frame 3 is attached in a state of being hooked on the new frame 2, and the longitudinal ends of the attachment upper frame 31 and the attachment vertical frame 33 are fixed to each other with screws 34, and the longitudinal ends of the attachment lower frame 32 and the attachment vertical frame 33 are fixed to each other with screws 34, whereby the attachment frame 3 can be firmly attached to the outside of the new frame 2. Further, since the attachment frame 3 is assembled and attached to the outside of the four circumferences of the new frame 2, the water-stopping performance can be improved.

[0096] In this embodiment, the longitudinal ends of the attachment upper frame 31 and the attachment vertical frame 33 and the longitudinal ends of the attachment lower frame 32 and the attachment vertical frame 33 are fixed to each other with screws 34, but the present invention is not limited to this. When the sizes of the attachment upper frame 31, the attachment lower frame 32, and the attachment vertical frame 33 are large, screw fixing may be performed at a position inside the longitudinal ends rather than at the longitudinal ends of the attachment upper frame 31 and the attachment vertical frame 33.

[0097] Next, as shown in FIG. 10, the new upper frame 21 and the attachment upper frame 31 are fixed with a plurality of screws 38 arranged along the longitudinal direction.

As shown in FIG. 11, the new vertical frame 23 and the attachment vertical frame 33 are fixed with a plurality of screws 38 arranged along the longitudinal direction. This allows the attachment frame 3 to be firmly fixed to the new frame 2. The number of screws 38 arranged along the longitudinal direction varies depending on the size of the new frame 2 and the attachment frame 3. For example, when the size of the new frame 2 and the attachment frame 3 is large, it becomes necessary to increase the number of screws from the viewpoint of fixing strength.

[0098] Next, the new frame 2 with the attachment frame 3 assembled thereto is inserted into the inside of the existing frame 6 from the indoor side X2 of the existing frame 6. Here, if the new frame 2 with the attachment frame 3 assembled thereto is inserted into the inside of the existing frame 6 while standing vertically from the indoor side X2 of the existing frame 6, the outdoor side vertical extension plate portion 313, the outdoor side vertical extension plate portion 323, and the indoor side indoor extension portion 333 of the attachment frame 3 will hit the existing frame 6. Therefore, the new frame 2 with the attachment frame 3 assembled thereto is inserted into the inside of the existing frame 6 while tilting it diagonally from the indoor side X2 of the existing frame 6, and is temporarily moved out to the outdoor side X1 of the existing frame 6, and then the new frame 2 with the attachment frame 3 assembled thereto is pulled from the outdoor side X1 of the existing frame 6 to the existing frame 6. As a result, the outdoor side vertical extension plate portion 313, the outdoor side vertical extension plate portion 323, and the indoor side indoor extension portion 333 of the attachment frame 3 are positioned close to the outdoor side X1 surface of the existing frame 6, and the attachment frame 3 is attached to the existing frame 6 and fixed in this state.

[0099] 19, the indoor side horizontal extension plate 314, the indoor side horizontal extension plate 324, and the indoor side indoor direction extension portion 333 of the attachment frame 3 are temporarily fixed to the building 100 (frame) with the screws .

[0100] Then, as shown in FIG. 20, a plurality of spacer members 37 are arranged between the indoor side horizontal extension plate 314, the indoor side horizontal extension plate 324, the indoor side indoor direction extension portion 333 and the frame member 101.

[0101] 21, the multiple spacer members 37 are arranged at multiple locations spaced apart in the longitudinal direction of the attachment upper frame 31 and the attachment vertical frame 33. The spacer members 37 are composed of multiple sheets, and the number of sheets is set according to the size of the gap between the indoor side horizontal extension plate 314, the indoor side horizontal extension plate 324, the indoor side indoor direction extension portion 333, and the frame member 101.

[0102] As shown in FIG. 20, the spacer member 37 has a U-shaped groove 371, and is inserted so that the U-shaped groove is arranged along the shaft of the screw 36. When attaching the attachment frame 3 to the existing frame 6, the spacer member 37 is arranged along the indoor side flat surface 314a, 324a, 333a formed on the same plane as the outer peripheral side flat surface 312a, 322a, 331a, as shown in FIG. 10 and FIG. 11. This allows the spacer member 37 to be stably arranged between the indoor side flat surface 314a, 324a, 333a and the frame member 101. In this state, the screw 36 is fixed. An example of the spacer member 37 is a thin plate-like member made of a resin material or the like.

[0103] 10 and 11, the renovated fitting 1 of this embodiment has an airtight structure 70 configured to connect the existing frame 6 side and the new frame 2 side with airtight tape (existing frame side airtight tape 71, connecting airtight tape 72). The airtight structure 70 has two airtight tapes (existing frame side airtight tape 71, connecting airtight tape 72), and by connecting the existing frame 6 and the attachment frame 3 attached to the new frame 2 with two airtight tapes (existing frame side airtight tape 71, connecting airtight tape 72), the airtight performance can be improved.

[0104] Specifically, in the airtight structure 70, the existing frame side airtight tape 71 is attached so as to span the existing frame 6 (existing upper frame 61, existing lower frame 62, existing vertical frame 63) and the building 100 (main body), and the connecting airtight tape 72 is attached so as to span the existing frame side airtight tape 71, the attachment frame 3 (attachment upper frame 31, attachment lower frame 32, attachment vertical frame 33), and the spacer member 37.

[0105] The existing frame side airtight tape 71 has a role of ensuring airtightness and watertightness between the existing vertical frame 63 and the building 100 (structure) and preventing moisture from being transmitted to the building 100 (structure) side. The connected airtight tape 72 ensures airtightness and watertightness between the attachment frame 3 (attachment upper frame 31, attachment lower frame 32, attachment vertical frame 33), the spacer member 37, and the building 100 (structure). The existing frame side airtight tape 71 attached to the existing frame 6 and the building 100 (structure) and the connected airtight tape 72 attached to the attachment frame 3 (attachment upper frame 31, attachment lower frame 32, attachment vertical frame 33) overlap each other, thereby improving airtightness and watertightness.

[0106] Next, as shown in FIG. 7, the indoor side decorative member 41 is attached to the surface of the attachment frame 3 on the indoor side X2 with the length of the tip side of the cover body 46 of the indoor side decorative member 41 adjusted.

[0107] 10 and 22, in the indoor side decorative member 41 to be attached to the newly installed upper frame 21, the mounting engagement plate 471 of the cover mounting portion 47 of the indoor side decorative member 41 is positioned between the projection direction extension piece 213a of the resin angle member 213 and the indoor side lower end horizontal protruding piece 316 of the attachment upper frame 31, as shown in Fig. 10 and 11, to engage the engagement protrusion 471a. This fits and holds the mounting engagement plate 471 of the cover mounting portion 47, temporarily fixing the indoor side decorative member 41.

[0108] In this temporarily fixed state, the worker can release his / her hands from the indoor side decorative member 41, and temporarily hold and temporarily fix the indoor side decorative member 41 between the forward extending piece 213a of the resin angle member 213 and the indoor side lower end horizontal protruding piece 316 of the attachment upper frame 31. In this state, the indoor side decorative member 41 is fixed by the screw 48 by moving the screw 48 from the lower side to the upper side. This allows the worker to release his / her hands from the indoor side decorative member 41, further improving the workability of installing the indoor side decorative member 41.

[0109] As shown in Figure 10, in the indoor side decorative component 41 to be attached to the newly installed lower frame 22, the cover mounting portion 47 of the indoor side decorative component 41 is positioned below the forward direction extension piece 223a of the resin angle component 223, and the screw 48 is moved from the upper side to the lower side and fixed with the screw 48.

[0110] 11, in the indoor side decorative member 41 to be attached to the newly installed vertical frame 23, the attachment engagement plate 471 of the cover attachment portion 47 of the indoor side decorative member 41 is disposed between the projection 233a of the resin angle member 233 and the indoor side end protruding piece 335 of the vertical attachment frame 33, thereby engaging the engagement protrusion 471a. This allows the attachment engagement plate 471 of the cover attachment portion 47 to be fitted and held in place, thereby temporarily fixing the indoor side decorative member 43.

[0111] In this temporarily fixed state, the worker can release his / her hands from the indoor side decorative member 43, and temporarily hold and temporarily fix the indoor side decorative member 43 between the projection piece 233a in the forward direction of the resin angle member 233 and the indoor side end projection piece 335 of the vertical attachment frame 33. In this state, the indoor side decorative member 43 is fixed by the screw 48 by moving the screw 48 from the inside to the outside in the left-right direction. This allows the worker to release his / her hands from the indoor side decorative member 41, making the installation work easier.

[0112] Next, as shown in Fig. 5, the exterior decorative covers 51, 52, 53 with the length of the tip side adjusted are attached to the surface of the exterior side X1 of the attachment frame 3. In this way, the exterior decorative covers 51, 52, 53 cover the unevenness of the attachment frame 3, and the flat surface of the exterior side X1 of the exterior decorative covers 51, 52, 53 is exposed to the exterior side X1, improving the design. Also, the exterior decorative covers 51, 52, 53 can be stably attached to the attachment frame 3 assembled all around.

[0113] According to this embodiment, the following effects are achieved. The remodeling fitting 1 of this embodiment is attached to the existing frame 6 provided at the opening of the building 100, and includes an attachment frame 3 attached to the inner periphery of the existing frame 6 in a state where the new frame 2 is attached to the outer periphery of the new frame 2 in a four-way configuration. The attachment frame 3 has flat outer periphery side planes 312a, 322a, and 331a formed on the outer periphery of the attachment frame 3, facing the existing frame 6, and extending in the indoor and outdoor directions. This makes it easy to arrange existing frames 6 of various shapes in the space along the flat outer periphery side planes 312a, 322a, and 331a. Therefore, the attachment frame 3 can be easily attached to existing frames 6 of various shapes.

[0114] In this embodiment, the attachment frame 3 has a front-facing extending plate portion (outdoor vertical extending plate portion 313, outdoor vertical extending plate portion 323, outdoor horizontal extending plate portion 332) arranged on the outdoor side and extending in the front-facing direction, and L-shaped spaces S1, S2, S3 are provided on the outer periphery of the attachment frame 3 along the indoor side surface of the front-facing extending plate portion (outdoor vertical extending plate portion 313, outdoor vertical extending plate portion 323, outdoor horizontal extending plate portion 332) and the outer periphery side planes 312a, 322a, 331a. This allows existing frames 6 of various shapes to be arranged along the L-shaped spaces S1, S2, S3. Therefore, the attachment frame 3 can be easily attached to existing frames 6 of various shapes.

[0115] In the present embodiment, the attachment frame 3 has hollow portions (the upper attachment frame hollow portion 312, the lower attachment frame hollow portion 322, and the vertical attachment frame hollow portion 331) in which the outer circumferential flat surfaces 312a, 322a, and 331a are formed. This can improve the strength of the attachment frame 3.

[0116] In this embodiment, the attachment frame 3 has extension plates (indoor horizontal extension plate 314, indoor horizontal extension plate 324, indoor indoor direction extension portion 333) extending from the hollow portions (attachment upper frame hollow portion 312, attachment lower frame hollow portion 322, attachment vertical frame hollow portion 331) to the indoor side, and the extension plates (indoor horizontal extension plate 314, indoor horizontal extension plate 324, indoor indoor direction extension portion 333) are fixed to the frame member 101 of the building 100 by screws 36. This allows the attachment frame 3 to be easily fixed to the building 100 at the extension plates (indoor horizontal extension plate 314, indoor horizontal extension plate 324, indoor indoor direction extension portion 333).

[0117] In addition, in this embodiment, the extension plates (indoor horizontal extension plate 314, indoor horizontal extension plate 324, indoor indoor direction extension portion 333) have spacer members 37 arranged between the indoor side flat surface 314a, 324a, 333a formed on the same plane as the outer periphery side flat surface 312a, 322a, 331a and the frame member 101. Therefore, when attaching the attachment frame 3 to the existing frame 6, the spacer members 37 can be arranged along the indoor side flat surface 314a, 324a, 333a formed on the same plane as the outer periphery side flat surface 312a, 322a, 331a. This allows the spacer members 37 to be stably arranged between the indoor side flat surface 314a, 324a, 333a and the frame member 101.

[0118] 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.

[0119] For example, as shown in the modified form shown in Fig. 24, for example, the optional member 11 may be configured to be attached to the indoor side X2 of the new sill 22A or the attachment sill 32A. By attaching the optional member 11 to the indoor side X2 of the new sill 22A or the attachment sill 32A, various members can be attached to the optional member 11. As shown in the modified form shown in Fig. 24, for example, when the remodeling fixture of this embodiment is applied to a bathroom remodeling fixture, a base material 12 for installing a picture frame for the bathroom or the like can be placed on the upper part of the optional member 11.

[0120] Also, for example, the width of the attachment frame 3 (upper attachment frame 31, lower attachment frame 32, vertical attachment frame 33) in the front direction may be formed larger than the width in the front direction of the above embodiment. For example, when a unit bath is constructed by applying the remodeling fitting of this embodiment to the opening of the entrance of a conventional bathroom where tiles are installed, the size of the opening of the unit bath may be made smaller than the opening of the conventional bathroom in order to ensure the strength of the wall of the unit bath. In such a case, by using the attachment frame 3 (upper attachment frame 31, lower attachment frame 32, vertical attachment frame 33) formed with a width in the front direction larger than the width in the front direction of the above embodiment, a remodeling fitting with a smaller opening size of the unit bath can be provided.

[0121] In the above embodiment, the remodeled fitting 1 is applied to a remodeled sash of a sliding window type, but the present invention is not limited to this. The remodeled fitting may be applied to, for example, an opening and closing type remodeled fitting in which the door rotates around a rotation axis to open and close, or a vertical sliding type remodeled fitting. The remodeled fitting may also be applied to, for example, a fixed type remodeled fitting that is fixed to the frame without opening or closing.

[0122] In the above embodiment, the airtight tape (existing frame side airtight tape 71, connecting airtight tape 72) is used in the airtight structure 70, but the present invention is not limited to this. In the airtight structure 70, for example, a sheet material (airtight adhesive sheet) having an adhesive provided on the attachment portion may be used. [Explanation of symbols]
