[0017] As shown in Fig. 6, the new frame 2 is attached to the existing frame 6 with the attachment frame 3 attached to the outer periphery. The new frame 2 is constructed from four sides and is attached to the inner periphery of the existing frame 6 via the attachment frame 3.

[0018] The new frame 2 includes a new upper frame 21, a new lower frame 22, and left and right new vertical frames 23. When the four sides of the new frame 2 are assembled, the new frame 2 is fixed with screws at the parts where the new upper frame 21, the new lower frame 22, and the left and right new vertical frames 23 join together. The attachment frame 3 includes an upper attachment frame 31, a lower attachment frame 32, and left and right vertical attachment frames 33.

[0019] When the new frame 2, with the attachment frame 3 attached to its outer periphery, is 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. 2. 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. 2. 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 between them, as shown in Figure 3, 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. 2 and Fig. 3, 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, as shown in Figure 6.

[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] As shown in Fig. 6, 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. As shown in Fig. 7, the lower attachment frame 32 has a front-direction extending plate 321 extending in the front direction at its end on the exterior side X1. The front-direction extending plate 321 is formed in a plate shape having a thickness in the indoor / outdoor direction, has a width in the up-down direction, and extends in the left-right direction. The upper attachment frame 31, the lower attachment frame 32, and the left and right vertical attachment frames 33 are each formed of, for example, an aluminum material.

[0026] 2 and 3, the upper attachment frame 31, the lower attachment frame 32, and the left and right vertical attachment frames 33 are each fixed to the (frame) of the building 100 by screws 36. When gaps are formed between the upper attachment frame 31, the lower attachment frame 32, and the left and right vertical attachment frames 33, respectively, and the frame member 101, spacer members 37 are disposed between the upper attachment frame 31, the lower attachment frame 32, and the left and right vertical attachment frames 33, respectively, and the frame member 101. An example of the spacer member 37 is a thin plate-like member formed of a resin material or the like.

[0027] 2 and 3, the remodeled fitting 1 has an airtight structure 70. The airtight structure 70 is 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) to the attachment frame 3 attached to the new frame 2. The airtight structure 70 is disposed to connect the existing frame 6 and the attachment frame 3 attached to the new frame 2 in order to improve the airtight performance between the existing frame 6 and the new frame 2.

[0028] 2 and 3, the indoor side decorative members 41, 42, and 43 are attached to the indoor side X2 surfaces of the resin angle members 213, 223, and 233 of the new frame 2. The boundaries between the indoor side decorative members 41, 42, and 43 and the inner peripheral surface of the frame member 101 are shielded by a trim member 45 with an L-shaped cross section that is fixed to the building 100 (structure).

[0029] 4 and 5, the exterior decorative covers 51, 52, 53 are attached to the surfaces of the exterior sides X1 of the upper attachment frame 31, the lower attachment frame 32, and the vertical attachment frame 33, respectively. As a result, the exterior decorative covers 51, 52, 53 cover the unevenness of the exterior sides X1 of the upper attachment frame 31, the lower attachment frame 32, and the vertical attachment frame 33, respectively, and the planar surfaces of the exterior sides X1 of the exterior decorative covers 51, 52, 53 are exposed to the exterior side X1, thereby improving the design.

[0030] 5, the multiple vertical position adjustment mechanisms 8 are provided at intervals in the left-right direction along the longitudinal direction of the attachment lower frame 32. The vertical position adjustment mechanisms 8 are capable of adjusting the position of the attachment frame 3 in the vertical direction.

[0031] As shown in Figures 7 to 11, the vertical position adjustment mechanism 8 includes an elongated hole 322 extending a predetermined length in the vertical direction, a slit 323 extending in the vertical direction, an adjustment member 81 that is movable in the vertical direction, a first screw 82, and a second screw 83.

[0032] The long hole 322 is formed in the front-direction extending plate 321 of the attachment lower frame 32, as shown in Figures 7 and 8. The long hole 322 penetrates the front-direction extending plate 321 of the attachment lower frame 32 in the indoor / outdoor direction. The long hole 322 extends a predetermined length in the vertical direction and is formed in an elongated hole shape with closed upper and lower ends. The shaft portion of the first screw 82 is disposed to penetrate the long hole 322 so as to be movably vertically.

[0033] The slit 323 is formed in the front-direction extending plate 321 of the attachment lower frame 32. The slit 323 is formed at a position a predetermined distance away from the long hole 322 on one side in the left-right direction, and is formed parallel to the long hole 322. The slit 323 penetrates the front-direction extending plate 321 of the attachment lower frame 32 in the indoor / outdoor direction, and is formed in a groove shape that is open at the lower end side and extends in the vertical direction. A step connection part 816 (described later) of the adjustment member 81 is arranged in the slit 323 so as to be movable in the vertical direction. By providing the slit 323 in the front-direction extending plate 321 of the attachment lower frame 32, the adjustment member 81 can be inserted and attached from the lower end side of the slit 323, making it easy to attach the adjustment member 81.

[0034] The adjustment member 81 is movable in the up and down direction along the slit 323. As shown in Figs. 7 to 11, the adjustment member 81 has a rear side plate portion 811 (first plate portion), a front side plate portion 815 (second plate portion), and a stepped connection portion 816 (connection portion).

[0035] The rear side plate portion 811 is disposed on the rear side (room side X2) of the front-direction extending plate 321 of the attachment lower frame 32. The rear side plate portion 811 has a vertical cross section formed into a crank shape. The rear side plate portion 811 has an upper rear side plate portion 812 disposed on the upper side, a lower rear side plate portion 813 disposed on the lower side, and a step plate portion 814 connecting the upper rear side plate portion 812 and the lower rear side plate portion 813.

[0036] The upper rear side plate 812 and the lower rear side plate 813 are both formed in a rectangular plate shape extending in the up-down and left-right directions. The upper rear side plate 812 and the lower rear side plate 813 are connected via a stepped plate 814, and when viewed from the outside side X1, are arranged side by side in the up-down direction and are arranged at positions shifted in the indoor-outdoor direction. The upper rear side plate 812 is arranged on the outside side X1, and the lower rear side plate 813 is arranged on the inside side X2.

[0037] The step plate portion 814 is formed as a horizontal plate having a width in the indoor / outdoor direction and extending in the left-right direction, and connects the upper rear side plate portion 812 and the lower rear side plate portion 813 in a step state.

[0038] The shaft of a first screw 82 is passed through an elongated hole 322 formed in the front-direction extending plate 321 and fixed to the upper rear side plate 812. The lower end 813a of the lower rear side plate 813 abuts against the upper surface of the horizontal plate 625 of the existing lower frame 62 when the vertical position of the adjustment member 81 is adjusted, as shown in FIG.

[0039] As shown in Figures 7 and 8, the front side plate portion 815 is connected to one side in the left-right direction of the back side plate portion 811 via a step connection portion 816, and is disposed on the front side (outside the room X1) of the front-direction extending plate 321 of the attachment lower frame 32. The front side plate portion 815 is formed in a rectangular plate shape extending in the up-down and left-right directions. A through hole 815a is formed in the front side plate portion 815. A second screw 83 is disposed to pass through the through hole 815a.

[0040] The step connection part 816 has an L-shaped cross section and connects the back side plate part 811 and the front side plate part 815. The step connection part 816 is arranged through the slit 323. The step connection part 816 is movable in the vertical direction along the slit 323 extending in the vertical direction. When viewed in the vertical direction in the cross section, the step connection part 816 extends a predetermined length from the end part of the back side plate part 811 on the front side plate part 815 side in the left-right direction through the slit 323 to the front side plate part 815 side, bends from the end part of the front side plate part 815 side to the outdoor side X1, extends a predetermined length to the outdoor side X1, and is connected to the front side plate part 815 at the end part on the outdoor side X1.

[0041] 9 and 11, the first screw 82 is arranged so that the shaft portion extends in the indoor / outdoor direction. The first screw 82 passes through the oblong hole 322 and is connected to the adjustment member 81. In detail, with the first screw 82 passing through the oblong hole 322, the head portion is arranged on the outdoor side X1 of the front-direction extending plate 321 of the attachment lower frame 32, and the shaft portion is arranged to pass through the oblong hole 322 and is connected to the adjustment member 81 on the indoor side X2 of the portion that passes through the oblong hole 322.

[0042] The first screw 82 is configured to pass through the elongated hole 322 and to be movable in the up-down direction along the elongated hole 322. Since the up-down position of the adjustment member 81 can be adjusted with the first screw 82 passing through the elongated hole 322, it is possible to prevent the adjustment member 81 from falling off while the up-down position of the adjustment member 81 is being adjusted. In addition, the first screw 82 can fix the adjustment member 81 and the attachment lower frame 32 in a state in which the up-down position of the adjustment member 81 has been adjusted. The head of the first screw 82 can fix the rear side plate portion 811 and the edge of the elongated hole 322 in the front direction extension plate 321 within any range of the up-down direction of the elongated hole 322.

[0043] The second screw 83 fixes the adjustment member 81 and the attachment lower frame 32 in a state where the vertical position of the adjustment member 81 has been adjusted. The second screw 83 is arranged so that the shaft portion extends in the indoor / outdoor direction, as shown in Fig. 10 and Fig. 11. The second screw 83 is a screw that fixes the front-side extending plate 321 of the attachment lower frame 32 and the front-side plate portion 815 of the adjustment member 81 so that the adjustment member 81 does not move in the vertical direction, as shown in Fig. 8, after adjusting the vertical position of the adjustment member 81 and fixing the back side plate portion 811 and the edge portion of the elongated hole 322 in the front-side extending plate 321 with the first screw 82.

[0044] The second screw 83 is a drill screw that fixes the front-side extending plate 321 of the attachment lower frame 32 and the front-side plate portion 815 of the adjustment member 81. As shown in Fig. 10 and Fig. 11, the second screw 83 is disposed so as to penetrate the through-hole 815a of the front-side plate portion 815 of the adjustment member 81 and the front-side extending plate 321 of the attachment lower frame 32 with the drill of the drill screw.

[0045] When adjusting the vertical position of the attachment frame 3 by the vertical position adjustment mechanism 8, as shown in Fig. 8, the first screw 82 passing through the elongated hole 322 is connected to the adjustment member 81 but not fixed to the edge of the elongated hole 322, and the vertical position of the adjustment member 81 is adjusted as shown in Fig. 9. Here, as shown in Fig. 8, the second screw 83 is not inserted into the through hole 815a of the front side plate portion 815 of the adjustment member 81, and the adjustment member 81 and the attachment lower frame 32 are not fixed together. In this state, it is possible to move the adjustment member 81 vertically along the slit 323.

[0046] Specifically, with the first screw 82 passing through the long hole 322 connected to the adjustment member 81, the step connection portion 816 of the adjustment member 81 is moved in the vertical direction along the slit 323, and the first screw 82 is moved in the vertical direction along the long hole 322 formed in the facing direction extension plate 321 of the attachment lower frame 32.

[0047] 9, a lower end 813a of the lower back side plate portion 813 of the adjustment member 81 abuts against the upper surface of the horizontal plate portion 625 of the existing lower frame 62. Therefore, by adjusting the vertical position of the adjustment member 81, the vertical distance between the attachment lower frame 32 and the existing lower frame 62 can be adjusted, and therefore the vertical positional relationship between the attachment lower frame 32 and the existing lower frame 62 can be adjusted.

[0048] Then, as shown in Fig. 9, with the vertical position of the adjustment member 81 adjusted and the vertical position determined, the first screw 82 is fixed to the edge of the elongated hole 322 in the front-direction extending plate 321 of the attachment lower frame 32. Furthermore, with the vertical position of the adjustment member 81 determined as shown in Fig. 8, the second screw 83 is inserted into the through-hole 815a in the front side plate 815 of the adjustment member 81, and as shown in Fig. 10, the second screw 83 is screwed into and penetrates the front-direction extending plate 321 of the attachment lower frame 32 using a drill screw to fix the adjustment member 81 and the attachment lower frame 32.

[0049] A plurality of the vertical position adjustment mechanisms 8 configured as described above are provided in line in the longitudinal direction of the attachment lower frame 32. Therefore, the vertical position of the attachment lower frame 32 can be adjusted at each predetermined position in the longitudinal direction of the attachment lower frame 32. As a result, the vertical position of the attachment lower frame 32 can be adjusted using each of the plurality of vertical position adjustment mechanisms 8 at each predetermined position in the longitudinal direction of the attachment lower frame 32, so that the new frame 2 can be adjusted to be horizontal in the left-right direction even if, for example, the existing frame 6 before renovation is distorted.

[0050] According to this embodiment, the following effects are achieved. The remodeling fixture 1 of this embodiment includes a new frame 2, an attachment frame 3, and a vertical position adjustment mechanism 8 that can adjust the vertical position of the attachment frame 3. The vertical position adjustment mechanism 8 includes an elongated hole 322 that extends a predetermined length in the vertical direction, a slit 323 that is open at the lower end and extends in the vertical direction, an adjustment member 81 that is configured to be movable in the vertical direction along the slit 323 and has a lower end 813a that abuts against the existing lower frame 62, and a slit 323 that is inserted through the elongated hole 322. The adjustment member 81 is equipped with a first screw 82, both of which are capable of fixing the adjustment member 81 and the attachment lower frame 32, and a second screw 83 that fixes the adjustment member 81 and the attachment lower frame 32. The adjustment member 81 has a rear side plate portion 811 arranged on the rear side of the facing direction extension plate 321, a front side plate portion 815 arranged on the front side of the facing direction extension plate 321, and a connection portion 816 arranged through the slit 323 and connecting the rear side plate portion 811 and the front side plate portion 815.

[0051] Therefore, the vertical position of the attachment frame 3 can be adjusted by moving the adjustment member 81 in the vertical direction along the slit 323 while the first screw 82 penetrating the long hole 322 is connected to the adjustment member 81. This allows the vertical position of the new frame 2 to be easily adjusted by adjusting the vertical position of the attachment frame 3 attached to the outer periphery of the new frame 2. In addition, since the first screw 82 can move along the long hole 322 that extends a predetermined length in the vertical direction, the adjustment member 81 can be moved in the vertical direction along the slit 323 that opens at the lower end and extends in the vertical direction while restricting the vertical movement range of the adjustment member 81 to the vertical range of the long hole 322. Therefore, the vertical position of the adjustment member 81 can be adjusted over a wide range.

[0052] Also, by providing the front-direction extending plate 321 of the attachment lower frame 32 with the slit 323 that is open at the bottom and extends in the vertical direction, the adjustment member 81 can be inserted into the slit 323 from the bottom end side, facilitating attachment of the adjustment member 81. In addition, by providing the front-direction extending plate 321 of the attachment lower frame 32 with the elongated hole 322, the vertical position of the adjustment member 81 can be adjusted with the first screw 82 passing through the elongated hole 322, so that the adjustment member 81 can be prevented from falling off while the vertical position of the adjustment member 81 is being adjusted.

[0053] In this embodiment, the first screw 82 can fix the rear side plate portion 811 and the edge of the elongated hole 322 in the front-direction extending plate 321, and the second screw 83 is a drill screw that penetrates and fixes the front-direction extending plate 321 and the front-direction extending plate portion 815. As a result, the first screw 82 can fix the adjustment member 81 to the edge of the elongated hole 322 in the front-direction extending plate 321, while the second screw 83, which is a drill screw, can firmly fix the adjustment member 81 to the front-direction extending plate 321 so as not to move in the vertical direction. Therefore, the adjustment member 81 can be easily fixed by the first screw 82, while the adjustment member 81 can be firmly fixed by the second screw 83 so as not to move the new frame 2 and the attachment frame 3 in the vertical direction.

[0054] Furthermore, in this embodiment, a plurality of vertical position adjustment mechanisms 8 are provided along the left-right direction (longitudinal direction) of the attachment lower frame 32. As a result, even if the existing frame 6 before reform is distorted, for example, the vertical position of the new frame 2 can also be adjusted by adjusting the vertical position of the attachment frame 3 by each of the plurality of vertical position adjustment mechanisms 8 at each position in the left-right direction of the attachment lower frame 32.
