[0008] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. The remodeling fixture 1 according to this embodiment is a bathroom door as a remodeling fixture for remodeling (renovation) in which a new frame 3 is attached to an existing frame 2 in a state where the existing frame 2 is attached to an opening of a building skeleton 100.

[0009] The existing frame 2 is constructed by assembling the existing upper frame 21, the existing lower frame 22, and a pair of existing vertical frames 23, 24 into a rectangle on all four sides. The new upper frame 31, the new lower frame 32, and a pair of new vertical frames 33, 34 that constitute the new frame 3 are in a disassembled state without being assembled on all four sides before installation, and are individually attached to the existing upper frame 21, the existing lower frame 22, and a pair of existing vertical frames 23, 24, respectively, and assembled into a rectangle on all four sides. In the renovated fitting 1 constructed by this construction method, there is no need to assemble the new frame 3 on all four sides in advance, which provides excellent workability.

[0010] In the following explanation, the prospective direction is the direction from the bathroom to the dressing room in the renovated fitting 1, or the opposite direction. The prospective direction is the direction along the surface direction of the surface material in the renovated fitting 1, and is the direction perpendicular to the prospective direction. In the drawings, the bathroom side as the exterior side of the renovated fitting 1 is referred to as the "bathroom side X1", and the dressing room side as the interior side of the renovated fitting 1 is referred to as the "dressing room side X2". The horizontal direction when the renovated fitting 1 is viewed from the front is referred to as the "left-right direction". The direction toward the center of the renovated fitting 1 when viewed from the front is referred to as the "inward direction", and the direction away from the center of the renovated fitting 1 is referred to as the "outward direction".

[0011] As shown in Figures 1, 2, etc., the existing frame 2 is formed by assembling four frame components, namely, an existing upper frame 21, an existing lower frame 22, and a pair of existing vertical frames 23, 24 on the left and right, in a rectangular shape, and is attached to the inside of an opening in the building structure 100 before renovation.

[0012] As shown in FIG. 2, a spotting member 101 is disposed on the dressing room side of the existing frame 2. The spotting member 101 is attached to the upper side and left and right sides of the inner periphery of the opening of the building structure 100, and is disposed in contact with or adjacent to the end face of the dressing room side X2 of the existing frame 2. The spotting member 101 is formed of wood, resin, or aluminum, and has a height approximately equal to the protruding height of the existing frame 2 from the inner periphery of the opening of the building structure 100, covering the spotting surface of the dressing room side X2 of the existing frame 2. The gap between the four-sided assembled existing frame 2 and the wall material 102 provided on the bathroom side X1 of the building structure 100 is sealed around the four sides with wet sealant 104.

[0013] As shown in Fig. 2, the existing upper frame 21 is positioned above the opening of the building structure 100. On the dressing room side of the existing upper frame 21, the upper part of the spotting member 101 is positioned in contact with or close to the existing upper frame 21. The gap between the existing upper frame 21 and the upper part of the wall material 102 provided on the bathroom side X1 of the building structure 100 is sealed with a wet sealant 104. As shown in Fig. 4, the existing upper frame 21 has a horizontal portion 211 and a vertical portion 212.

[0014] As shown in Fig. 2, the existing sill 22 is placed and fixed to the bottom of the opening in the building skeleton 100. A floor material 103 is placed in contact with or adjacent to the existing sill 22 on the dressing room side of the existing sill 22. The gap between the existing sill 22 and the bottom of the wall material 102 provided on the bathroom side X1 of the building skeleton 100 is sealed with a wet sealant 104. As shown in Fig. 5, the existing sill 22 has a horizontal portion 221 and a vertical portion 222.

[0015] As shown in Fig. 3, the existing vertical frames 23, 24 are arranged and fixed to the left and right vertical portions of the opening of the building skeleton 100. On the changing room side of the existing vertical frames 23, 24, the left and right portions of the sight member 101 are arranged in contact with or close to the existing vertical frames 23, 24. Gaps between the existing vertical frames 23, 24 and the left and right portions of the wall material 102 provided on the bathroom side X1 of the building skeleton 100 are sealed with wet sealant 104. The existing vertical frame 23 has a prospective portion 231 and a prospective portion 232. The existing vertical frame 24 has a prospective portion 241 and a prospective portion 242 as shown in Fig. 7.

[0016] The new frame 3 has a new upper frame 31 fixed to the underside of the existing upper frame 21, a new lower frame 32 fixed to the upper side of the existing lower frame 22, and new vertical frames 33, 34 fixed to the inside of the left and right existing vertical frames 23, 24. The new upper frame 31, the new lower frame 32, and the new vertical frames 33, 34 are all composed of long members.

[0017] More specifically, the new upper frame 31 has a length sufficient to cover the entire lower surface of the existing upper frame 21 in the rectangularly framed existing frame 2. The new lower frame 32 has a length sufficient to cover the entire upper surface of the existing lower frame 22 in the rectangularly framed existing frame 2. The new vertical frames 33, 34 have a length sufficient to cover the entire inner surfaces of the left and right existing vertical frames 23, 24 in the rectangularly framed existing frame 2.

[0018] 4, the new upper frame 31 is formed in an L-shape having a horizontal portion 311 and a vertical portion 312 in a cross section in the longitudinal direction of the new upper frame 31. The horizontal portion 311 faces the horizontal portion 211 of the existing upper frame 21, and has a guide rail 311a that protrudes downward to guide the new folding door 5.

[0019] The end of the horizontal section 311 on the bathroom side X1 is formed in a T-shape with a rib 311b as a downward extension that extends vertically downward. The lower end of the rib 311b is located below the base side part of the horizontal section 311 connected to the rib 311b. This makes it possible for water droplets adhering to the rib 311b to drip from the lower end of the rib 311b along the rib 311b, and as a result, it is possible to prevent the water droplets from flowing into the existing frame 2, the new frame 3, or along the horizontal section 311 to the changing room side X2.

[0020] A wet sealing 214, which is configured by filling a sealant, is provided between the upper end of the rib 311b and the horizontal portion 211. The wet sealing 214 abuts against the upper end of the rib 311b and the horizontal portion 211, and the wet sealing 214 provides a liquid-tight seal between the upper end of the rib 311b and the horizontal portion 211.

[0021] In addition, a wet sealing 215 is provided between the visible surface of the vertical portion 312 on the changing room side X2 and the lower end of the vertical portion 212, and is configured by filling the sealing material. The wet sealing 215 is provided by filling a sealing material into a sealing pocket formed between a rib 311c provided in the vertical portion 312 protruding from the visible surface of the changing room side X2 toward the changing room side and the lower end of the vertical portion 212. This makes it possible to retain the sealing material before it solidifies in the sealing pocket, making it possible to prevent the sealing material from leaking out and also making it possible to achieve a beautiful finish. The wet sealing 215 provides a liquid-tight seal between the vertical portion 312 and the vertical portion 212.

[0022] 5, the new lower frame 32 is formed in an L-shape having a horizontal portion 321 and a vertical portion 322 in a cross-sectional view in the longitudinal direction of the new lower frame 32. The horizontal portion 321 faces the horizontal portion 221 of the existing lower frame 22 and has a guide rail 321a that protrudes upward and guides the new folding door 5.

[0023] The portion of the horizontal section 321 on the bathroom side X1 above the guide rail 321a has an inclined surface 321c that gently slopes downward toward the bathroom side X1. This allows water droplets that fall on the inclined surface 321c to flow along the inclined surface 321c to the bathroom side X1. This makes it possible for water droplets that fall on the inclined surface 321c to be easily drained to the bathroom side X1, improving drainage performance.

[0024] The end of horizontal part 321 on the bathroom side X1 is formed in an L shape, with rib 321b as a downward extension that extends vertically downward. The lower end of rib 321b is located below the base side part of horizontal part 321 connected to rib 321b. This allows water droplets that have flowed up to rib 321b to flow along rib 321b to the lower end of rib 321b, and as a result, water droplets on rib 321b can be easily drained to the bathroom side X1, improving drainage performance.

[0025] A wet sealing 224, which is configured by filling a sealant, is provided between the lower end of the rib 321b and the horizontal portion 221. The wet sealing 224 abuts against the rib 321b and the horizontal portion 221, and the wet sealing 224 provides a liquid-tight seal between the rib 321b and the horizontal portion 221.

[0026] In addition, a wet sealing 225 configured by filling a sealant is provided between the vertical portions 322 and 222 in the up-down direction. The wet sealing 225 provides a liquid-tight seal between the vertical portions 322 and 222.

[0027] 6, the new vertical frame 33 is formed in an L-shape having a projection portion 331 and a projection portion 332 in a cross-sectional view in the longitudinal direction of the new vertical frame 33. The projection portion 331 faces the projection portion 231 of the existing vertical frame 23.
