[0062] The indoor-side covering material body 81 has a length in the longitudinal direction of the indoor-side covering material body 81 that is the same as the length in the longitudinal direction of the upright 5. The indoor-side covering material body 81 is configured so that its length can be adjusted in the direction spanning the new frame 3A on one side and the new frame 3B on the other side, which are left and right across the upright 5 in the visible direction, for example, by being cut along the cut line shown by the two-dot chain line in Fig. 3. The parts of the indoor-side covering material body 81 that are left and right of the cut line (the part to the left of the two-dot chain line on the left side in Fig. 3 and the part to the right of the two-dot chain line on the right side in Fig. 3) are removed as unnecessary parts.

[0063] In this way, both widthwise ends of the indoor-side covering material main body 81 from which unnecessary portions have been removed are covered by end caps 84. The both ends covered by end caps 84 are arranged close to and opposite the indoor-side covering material opposing parts 76 and 77, respectively. Both longitudinal ends of the indoor-side covering material main body 81 are covered by upper and lower end caps 85.

[0064] The hollow portion 82 is formed at the center position of the indoor-side cover material main body 81 in the left-right direction across the upright 5 in the view direction. The interior of the hollow portion 82 is divided into multiple sections along the width direction (left-right direction in Figure 3) in the view direction of the indoor-side cover material main body 81. Hook-shaped engaging portions 83 extending toward the outside X1 are provided at both ends of the hollow portion 82 in the width direction (left-right direction in Figure 3) in the view direction.

[0065] At a position facing the hollow portion 82 on the outdoor side X1, a locking member 56 is provided which is fixed to the upright indoor side cover material 53 with a screw 161. As shown in Figure 3, the locking member 56 has a locking member main body 561 formed in the shape of a rectangular plate, and a rib portion 562 which extends from the indoor side X2 surface of the locking member main body 561 to the indoor side X2.

[0066] The locked portions 83 are locked to both ends of the locking member main body 561 in the width direction (left and right direction in Figure 3) in the view direction. In this way, the indoor-side covering material main body 81 is locked to the mullion 5 via the locked portions 83, locking members 56, mullion indoor-side covering material 53, connecting members 52, etc., so that the indoor-side covering material main body 81 is locked to the renovated fitting 1 so as to cover the new frame 3A on one side to the new frame 3B on the other side that make up the continuous window, including the mullion 5, and the covering material 8 is positioned opposite the indoor side of the mullion 5 and attached to the renovated fitting 1.

[0067] This allows the indoor side X2 of the mullion 5 to be covered with the covering material 8, preventing the mullion 5 from being exposed and improving the design. This type of configuration can be easily achieved by fastening the indoor-side covering material main body 81 to the mullion 5. In particular, because the indoor-side covering material main body 81 is fastened to the mullion 5 via the mullion indoor-side covering material 53, it is possible to increase the degree of freedom in designing the configuration for fastening the indoor-side covering material main body 81 to the mullion 5, and it is possible to improve workability.

[0068] In addition, a single plate-shaped indoor covering material body 81 is engaged with the renovated fixture 1 and positioned so as to cover the area from the new frame 3A on one side to the new frame 3B on the other side that make up the continuous window, including the mullion 5, which makes it easier to install compared to when it is made up of multiple plate-shaped components, and also makes it possible to block heat from the existing frames 2A and 2B.

[0069] Furthermore, since the indoor-side covering material main body 81 is locked to the upright 5 via the locked portion 83, the locking member 56, the upright indoor-side covering material 53, the connecting member 52, etc., it is possible to configure the screws 161 for fixing the locking member 56 to the upright indoor-side covering material 53 to be hidden so that they cannot be seen from the indoor side X2. This makes it possible to improve the design.

[0070] Next, a second embodiment of the present disclosure will be described. In the second embodiment, the configuration of the cover material 8A differs from the configuration of the cover material 8 in the first embodiment. Accordingly, the configuration in which the cover material 8A is fastened differs from the configuration in which the cover material 8 is fastened in the first embodiment. Since the other configurations are the same as those in the first embodiment, the same reference numerals are used and the description will be omitted.

[0071] The cover material 8A includes an indoor-side cover material main body 81A. The indoor-side cover material main body 81A is formed as a single, seamless rectangular plate. The indoor-side cover material main body 81A has a width greater than the width of the upright 5 in the left-right direction across the upright 5 in the facing direction, and covers the indoor side X2 of the renovated fitting 1A from the entire new frame 3A as the new frame on one side in the facing direction to a portion of the new frame 3B as the new frame on the other side.

[0072] The indoor-side cover material main body 81A has a length in the longitudinal direction thereof that is the same as the length in the longitudinal direction of the uprights 5. A pair of hook-shaped engaging portions 814A extending toward the outdoor side X1 are provided at the center of the width direction (left-right direction in Figure 4) in the view direction of the indoor-side cover material main body 81A.

[0073] A locking member 56A is provided at a position on the outside surface X1 opposite the central portion of the indoor-side covering material main body 81A where the locked portion 814A is provided, and is fixed to the upright indoor-side covering material 53 with screws 161. As shown in Fig. 4, the locking member 56A has a locking member main body 561A formed in the shape of a rectangular plate, a rib portion 562A extending from the surface of the indoor-side X2 side of the locking member main body 561A toward the indoor-side X2, and a pair of hook-shaped locking portions 563A provided at the central portion of the width direction (left-right direction in Fig. 4) of the locking member 56A in the viewing direction and extending toward the indoor-side X2.

[0074] The locked portions 814A are locked to the locking portions 563A, respectively. As a result, the cover material 8A is locked to the mullion 5 via the locking members 56A, the mullion room-side cover material 53, the connecting members 52, etc., and is attached to the remodeled fitting 1A.

[0075] A plurality of rib-like opposing portions 813A extending from the indoor-side covering material main body 81A to the outdoor side X1 are provided at predetermined intervals on both end portions 812A in the width direction (left-right direction in Fig. 4) of the indoor-side covering material main body 81A. The indoor-side covering material main body 81A is configured so that its length can be adjusted in the direction spanning the new frame 3A on one side and the new frame 3B on the other side, which is the left-right direction across the upright 5 in the viewing direction, for example, by being cut along the cut line shown by the two-dot chain line in Fig. 4. The portions of the indoor-side covering material main body 81A outside the cut line in the left-right direction (the portion to the left of the two-dot chain line on the left side in Fig. 4 and the portion to the right of the two-dot chain line on the right side in Fig. 4) are removed as unnecessary portions.

[0076] In this way, the opposing portions 813A at both ends in the width direction of the indoor-side covering material main body 81A from which unnecessary portions have been removed are arranged close to and opposing the indoor-side covering material opposing portion 76 and the indoor-side covering material opposing portion 77. Wet sealant 84A is filled between the opposing portion 813A and the indoor-side covering material opposing portion 76, and between the opposing portion 813A and the indoor-side covering material opposing portion 77.

[0077] Next, a third embodiment of the present disclosure will be described. In the third embodiment, the configuration of the cover material 8B differs from the configuration of the cover material 8 in the first embodiment. Accordingly, the configuration in which the cover material 8B is locked differs from the configuration in which the cover material 8 is locked in the first embodiment.

[0078] The cover material 8B comprises an indoor-side cover material main body 81B and a hollow portion 82B. The indoor-side cover material main body 81B is formed as a rectangular plate with a central hollow portion 82B in the left-right direction across the mullion 5 in the facing direction, protruding toward the indoor side X2. The indoor-side cover material main body 81B has a width wider than the width of the mullion 5 in the left-right direction across the mullion 5 in the facing direction, and covers the indoor side X2 of the renovated fitting 1B from the entire new frame 3A as the new frame on one side in the facing direction to a portion of the new frame 3B as the new frame on the other side. The indoor-side cover material main body 81B has a length in the longitudinal direction of the indoor-side cover material main body 81B that is the same as the length in the longitudinal direction of the mullion 5.

[0079] The hollow portion 82B is formed at the center position of the indoor-side covering material main body 81B in the left-right direction across the mullion 5 in the view direction. The interior of the hollow portion 82B is divided into multiple sections along the width direction (left-right direction in Figure 5) of the indoor-side covering material main body 81B in the view direction. The outdoor side X1 part of the hollow portion 82B is fixed to the mullion indoor-side covering material 53 with double-sided tape (adhesive tape). In this way, the covering material 8B is fixed to the mullion 5 via the mullion indoor-side covering material 53, connecting member 52, etc.

[0080] A first-side locking portion 76B is fixed with screws 145 to the lower part of the angle member 74 attached to the end of the new vertical frame 34 on the indoor side X2. As shown in FIG. 5, the first-side locking portion 76B has a C-shape that opens outward in the left-right direction (to the right in FIG. 5), and the opening is formed by the space between a bottom 763B of the first-side locking portion 76B and a hook-shaped portion 764B of the first-side locking portion 76B. One end of the cover material 8B is inserted through the opening, and the hook-shaped portion 764B becomes hooked into numerous fine grooves 815B provided on the surface of the first end of the cover material 8B facing the outdoor side X1, and the one end of the cover material 8B is locked to the first-side locking portion 76B.

[0081] The other-side locking portion 77B is fixed to the lower part of the angle member 75 attached to the end of the new vertical frame 35 on the indoor side X2 by a screw 155.
