Description

[Technical field]

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

[0002] A known configuration for a remodeled bathroom door is one in which a new frame is installed so as to cover an 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] If a new frame is installed to cover the existing frame, the height from the floor will be increased by the height of the new lower frame that constitutes the lower part of the new frame, and the height of the step created by the new lower frame will be high. Therefore, there is a risk that the step will become an obstacle when a wheelchair passes over the lower frame.

[0005] The present disclosure aims to provide a retrofit bathroom door that allows easy wheelchair passage. [Means for solving the problem]

[0006] The present disclosure relates to a renovated bathroom door that comprises an existing frame that is attached to an opening in a building structure, a new frame that is attached to the inner periphery of the existing frame, and a step-eliminating member that covers the step formed by the existing frame and forms a sloped surface. [Brief description of the drawings]

[Figure 8] 4 is an enlarged cross-sectional view of a portion surrounded by A in FIG. 2 according to the second embodiment.

[0008] Hereinafter, a first 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 locating member 101 is disposed on the dressing room side of the existing frame 2. The locating 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 close to the end face of the dressing room side X2 of the existing frame 2. The locating 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 locating surface of the dressing room side X2 of the existing frame 2. The gap between the four-sided assembled existing frame 2 and the bathroom floor material 105 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.

[0014] As shown in Fig. 2, the existing sill 22 is placed and fixed at the bottom of the opening in the building structure 100. A floor material 103 is placed in contact with or close to the existing sill 22 on the dressing room side of the existing sill 22. The gap between the existing sill 22 and a bathroom floor material 105 provided on the bathroom side X1 of the building structure 100 is sealed with a wet sealant 104. 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 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. 5, 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 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] The front end of the horizontal portion 221 bends downward to form a front wall having a visible surface. On the bathroom side X1 facing the visible surface, an inclined member 227 is provided as a step-eliminating member. As shown in FIG. 4, the inclined member 227 is made of a long, hollow member having the same length as the existing lower frame 22. The inclined member 227 has an inclined surface portion 227b as its upper surface, which inclines downward as it approaches the bathroom side X1, and a stepped bottom portion 227a that supports the inclined surface portion 227b below the inclined surface portion 227b. The stepped bottom portion 227a and the inclined surface portion 227b are integrally formed from an aluminum alloy.

[0024] This allows the inclined member 227 to cover the step formed by the front wall with a downwardly bent visible surface at the front end of the horizontal section 221. As a result, when the wheelchair climbs over the raised bathroom door and enters the bathroom side X1 by installing the new lower frame 32 on the existing lower frame 22, the wheelchair can move along the inclined surface portion 227b. This makes it possible to approach a barrier-free environment.

[0025] In addition, since the inclined member 227 has a stepped bottom 227a, even if there is a protruding part such as a wet sealing 104 below the inclined member 227, it is possible to position the inclined member 227 in an appropriate position.

[0026] 5, 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] Next, a second embodiment of the present disclosure will be described. The second embodiment differs from the first embodiment in that the inclination member 227A is made of a solid member. Other configurations are the same as those of the first embodiment, so the same members are denoted by the same reference numerals and will not be described.

[0031] 6 and 7, the inclined member 227A is made of a solid rubber material. Like the inclined member 227 of the first embodiment, the inclined member 227A has an inclined surface portion 227Ab that slopes downward toward the bathroom side X1 as the upper surface, and a stepped bottom portion 227Aa that forms the bottom of the inclined member 227A.

[0032] Next, a third embodiment of the present disclosure will be described. In the third embodiment, the height of the apex 227Bc of the inclination member 227B is different from the height of the apex of the inclination member 227 in the first embodiment. Since the other configurations are the same as those in the first embodiment, the same members are illustrated with the same reference numerals and the description thereof will be omitted.

[0033] As shown in the cross-sectional view of Fig. 8, the inclined member 227B is formed in a shape similar to the hollow inclined member 227 of the first embodiment, which is enlarged. The inclined member 227B may be solid, instead of hollow, like the inclined member 227A of the second embodiment. As shown in Fig. 8, like the inclined member 227 of the first embodiment, the inclined member 227B has an inclined surface portion 227Bb on the upper surface that slopes downward toward the bathroom side X1, and a stepped bottom portion 227Ba that forms the bottom of the inclined member 227B.

[0034] The height of the apex 227Bc of the inclined member 227B is substantially the same as the height of the guide rail 321a. Here, the phrase "the height of the apex 227Bc of the inclined member 227B and the height of the guide rail 321a are substantially the same" means not only that they are completely the same, but also that when the wheels of a wheelchair (not shown) move from the floor material 103 over the guide rail 321a to the apex 227Bc of the inclined member 227B, the difference in height between the upper surface of the floor material 103 and the upper end of the guide rail 321a, and between the upper end of the guide rail 321a and the apex 227Bc of the inclined member 227B is within a range where a wheelchair user sitting in the wheelchair does not notice the step.

[0035] This makes it possible to prevent the wheelchair from moving smoothly through the sloped surface portion 227Bb of the sloped member 227B from hitting the step with its wheels when the wheelchair moves from the floor material 103 to the sloped surface portion 227Bb of the sloped member 227B.

[0036] 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.

[0037] For example, the inclination member 227 and the inclination member 227A are made of an aluminum alloy and a rubber material, but are not limited to these. [Explanation of symbols]
