Abstract
Description
[Technical field]
[0001] The present disclosure relates to retrofit fittings. [Background technology]
[0002] In a remodeling fixture, a configuration is known in which a rail for guiding a folding door in an existing frame is provided on the inner peripheral surface of the existing frame (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent Publication No. 2022-020982 Summary of the Invention [Problem to be solved by the invention]
[0004] In the remodeling fixture described in the above publication, after a new frame is installed so as to straddle the rail, a sealant is filled between the existing frame and the new frame, so-called wet sealing is provided. In wet sealing, the sealant is fluid from the time it is applied until it dries, so it is required to keep the sealant in a specified position. In addition, if the visible width of the wet sealing is large, it is not beautiful, and furthermore, dirt on the sealant becomes noticeable due to deterioration over time, so it is required to improve the design.
[0005] The present disclosure aims to provide a remodeling fixture that has improved workability when installing wet sealing and improved design. [Means for solving the problem]
[0006] The present disclosure relates to a renovation fixture comprising an existing frame that is attached to an opening in a building structure and a new frame that is attached to the inner periphery of the existing frame, wherein the new frame has a protruding piece that spans a protrusion protruding from the inner periphery of the existing frame, and the tip of the protruding piece has a prospective surface that faces the existing frame. [Brief description of the drawings]

[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 of the renovated fitting 1 is referred to as the "bathroom side X1", and the dressing room 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 Figure 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 sight 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 Figure 4, the existing upper frame 21 has a horizontal part 211 and a vertical part 212. The horizontal part 211 has a guide rail 211a for the existing folding door that protrudes downward.
[0014] As shown in Fig. 2, the existing sill 22 is disposed and fixed to the lower part of the opening of the building structure 100. A floor material 103 is disposed 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 lower 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. 5, the existing sill 22 has a horizontal part 221 and a vertical part 222. The horizontal part 221 has a guide rail 221a for the existing folding door that protrudes upward.
[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 dressing 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. The 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. As shown in Fig. 6, the existing vertical frame 23 has a sight portion 231 and a sight portion 232. The existing vertical frame 24 is configured symmetrically to the existing vertical frame 23, and a description thereof will be omitted.
[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 a T-shape having a horizontal portion 311 and a vertical portion 312 in a cross-sectional view 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 has a rib 311b as an upward extension that extends vertically upward, and the upper end of the rib 311b extends to the dressing room side X2 and has a ceiling support section 311d facing the horizontal section 211, forming a U-shape.
[0020] The lower end of the rib 311b is located below the base side portion of the horizontal section 311 connected to the rib 311b and forms a downward extension. This allows 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.
[0021] The upper surface of the sealing support part 311d constitutes a prospective surface facing the lower surface of the horizontal part 211. The space between the prospective surface and the lower surface of the horizontal part 221 constitutes a sealing pocket. A wet sealing 214 constituted by filling a sealant is provided between the prospective surface and the lower surface of the horizontal part 211. The wet sealing 214 abuts against the prospective surface, which is the upper surface of the sealing support part 311d, and the lower surface of the horizontal part 211, and the wet sealing 214 provides a liquid-tight seal between the sealing support part 311d and the horizontal part 211.
[0022] As a result, when filling the sealant that will become the wet sealant 214, it is sufficient to fill an appropriate amount of sealant that can be placed on the projected surface, which is the upper surface of the sealing support portion 311d, so it is possible to prevent filling more sealant than necessary, and it is possible to reduce construction costs. In addition, since it is possible to prevent filling more sealant than necessary, it is possible to prevent the visible width of the wet sealant 214 from becoming large. As a result, it is possible to prevent dirt due to aging deterioration of the wet sealant 214 from becoming noticeable, and it is possible to improve the design.
[0023] As shown in FIG. 4, the horizontal part 311 including the rib 311b and the sealing support part 311d, and the vertical part 312, which is above the part of the vertical part 312 that is integrally formed and connected to the horizontal part 311, are formed in a U-shape that opens upward. This part straddles the guide rail 211a in a positional relationship in which the guide rail 211a is located inside the U-shape. This makes it possible to eliminate the need to cut out the guide rail 211a of the existing frame 2, and improves workability. In addition, since the upper end of the vertical part 312 abuts against the horizontal part 211, it is possible to position the vertical part 312 relative to the horizontal part 211.
[0024] A wet sealing 215 filled with a sealant is provided between the facing surface of the vertical portion 312 on the changing room side X2 and the lower end of the vertical portion 212. The wet sealing 215 provides a liquid-tight seal between the vertical portion 312 and the vertical portion 212.
[0025] 5, the new lower frame 32 is formed in a T-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.
[0026] 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.
[0027] The end of the horizontal section 321 on the bathroom side X1 has a rib 321b as a downward extension that curves and extends downward, and the lower end of the rib 321b has a sealing support section 321d that extends toward the changing room side X2 and faces the horizontal section 221, forming a U-shape.
[0028] The lower end of rib 321b is located below the base side portion of horizontal section 321 connected to rib 321b. This allows water droplets that reach rib 321b to flow along rib 321b to the lower end of rib 321b, making it possible for water droplets on rib 321b to be easily drained to bathroom side X1, improving drainage performance.
[0029] The lower surface of the sealing support part 321d constitutes a projected surface facing the upper surface of the horizontal part 221. The space between the projected surface and the upper surface of the horizontal part 221 constitutes a sealing pocket. A wet sealing 224 constituted by filling a sealant is provided between the projected surface and the upper surface of the horizontal part 221. The wet sealing 224 abuts against the projected surface, which is the lower surface of the sealing support part 321d, and the upper surface of the horizontal part 221, and the wet sealing 224 provides a liquid-tight seal between the sealing support part 321d and the horizontal part 221.
[0030] As a result, when filling the sealant that will become the wet sealant 224, it is sufficient to fill an appropriate amount of sealant that can be placed on the projected surface, which is the lower surface of the sealing support portion 321d, so it is possible to prevent filling more sealant than necessary, and it is possible to reduce construction costs. In addition, since it is possible to prevent filling more sealant than necessary, it is possible to prevent the visible width of the wet sealant 224 from becoming large. As a result, it is possible to prevent dirt due to deterioration over time of the wet sealant 224 from becoming noticeable, and it is possible to improve the design.
[0031] As shown in FIG. 5, the horizontal part 321 including the rib 321b and the sealing support part 321d, and the vertical part 322, which is lower than the part of the vertical part 322 that is integrally formed and connected to the horizontal part 321, are formed in a U-shape that opens downward. This part straddles the guide rail 221a in a positional relationship in which the guide rail 221a is located inside the U-shape. This makes it possible to eliminate the need to cut out the guide rail 221a of the existing frame 2, and improves workability. In addition, since the lower end of the vertical part 322 abuts against the horizontal part 221, it is possible to position the vertical part 322 relative to the horizontal part 221.
[0032] 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.
[0033] 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.
[0034] The bathroom side X1 end of the projection portion 331 has a rib 331b extending outward in the front direction, and is formed in an L shape. A wet sealing 234 filled with a sealant is provided between the front-outer end of the rib 331b and the projection portion 231. The wet sealing 234 abuts against the front-outer end of the rib 331b and the projection portion 231, and the wet sealing 234 provides a liquid-tight seal between the front-outer end of the rib 331b and the projection portion 231.
[0035] In addition, a wet sealing 235 filled with a sealant is provided between the facing portion 332 and the end of the facing portion 232 on the inner side in the facing direction. The wet sealing 235 abuts against the facing surface of the facing portion 332 on the changing room side X2 and the end of the facing portion 232 on the inner side in the facing direction, and the wet sealing 235 provides a liquid-tight seal between the facing portions 332 and 232. The new vertical frame 34 is configured symmetrically to the new vertical frame 33, and a description thereof will be omitted.
[0036] As shown in Figs. 1 to 3, the newly installed folding door 5 has two sliding doors 5a, 5b, each of which is made of a resin panel separated into upper and lower parts by middle bars 57, 58, and is attached between the door end frame 51 and the middle frame 52 and between the hanging frame 53 and the middle frame 52 via auxiliary frames 54, 55. Each auxiliary frame 54, 55 is rotatably supported by the middle frame 52. This allows each sliding door 5a, 5b to be foldably attached to the middle frame 52. A handle 58a extending parallel to the middle frame 58 is fixed to the middle frame 58.
[0037] Next, a second embodiment of the present disclosure will be described. In the second embodiment, the configurations of the vertical portion 312A of the new upper frame 31 and the vertical portion 322A of the new lower frame 32 are different from the configurations of the vertical portion 312 of the new upper frame 31 and the vertical portion 322 of the new lower frame 32 in the first embodiment. Since the configuration other than this is the same as the configuration of the first embodiment, the same members are illustrated with the same reference numerals and the description will be omitted.
[0038] 7 and 8, the upper end of the vertical portion 312A is not in contact with the horizontal portion 211, but is spaced apart from and located below the horizontal portion 211. Therefore, when it is not necessary to position the vertical portion 312A relative to the horizontal portion 211, such a configuration is possible.
[0039] 7 and 9, the upper end of the vertical portion 322A is not in contact with the horizontal portion 221, but is spaced apart from the horizontal portion 221 and located above the horizontal portion 221. Therefore, when it is not necessary to position the vertical portion 322A relative to the horizontal portion 221, such a configuration is possible.
[0040] Although the preferred embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments and may be modified as appropriate.
[0041] For example, the remodeling fixture 1 according to the present embodiment is a bathroom door for remodeling (remodeling), but is not limited thereto. For example, the remodeling fixture may be a remodeling sash, a front door, or a back door.
[0042] In addition, in this embodiment, the upper extension portion is formed by the rib 311b, and the lower extension portion is formed by the rib 321b, but this is not limited to this. The upper extension portion only needs to have a shape that extends upward from the part of the newly installed upper frame to which the upper extension portion is connected. The lower extension portion only needs to have a shape that extends downward from the part of the newly installed lower frame to which the lower extension portion is connected.
[0043] In the first and second embodiments, the heights of the guide rails 211a and 221a are the same, but this is not limited to this. Depending on the height of the guide rails, new upper and lower frames having vertical parts at a height that allows them to straddle the guide rails and ribs at the ends of the horizontal parts may be used.
