Description

[Technical Field]

[0001] The present disclosure relates to fittings and methods for installing fittings. [Background technology]

[0002] Conventionally, there is known a fitting that includes a frame body having an upper frame, a shoji screen arranged within the frame body so as to be movable laterally, an upper rail attached to the underside of the upper frame, and a hoist provided above the shoji screen and attached to the upper rail (see, for example, Patent Document 1). In the fitting described in Patent Document 1, a part of the upper rail where the hoisting screen does not run is cut out, and the hoisting screen is attached to the upper rail by inserting the hoisting screen through the cutout. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-38312 Summary of the Invention [Problem to be solved by the invention]

[0004] Some shoji screens, which open and close by sliding horizontally, employ a soft-close mechanism that closes gently when opened and closed. When a soft-close mechanism is attached to a fixture, the hoist and a long soft-close component are constructed as a single unit and attached to the upper rail. When the hoist and soft-close component are constructed as a single unit, the soft-close component is long, so a structure in which a portion of the upper rail is cut out and inserted requires the notch to be large. However, if the notch is made too large, the hoist cannot move through the cutout. Therefore, it has been difficult to attach the hoist and soft-close component, which are constructed as a single unit, to the upper rail.

[0005] The present disclosure aims to provide a fixture and a method for installing the fixture that allows an integrally constructed hoist and soft-close part to be easily attached to an upper rail. [Means for solving the problem]

[0006] The present disclosure relates to a fixture comprising a frame body having an upper frame, a shoji screen arranged within the frame body so as to be movable laterally, an upper rail arranged between the upper frame and the shoji screen and fixed to the upper frame at the underside of the upper frame, a hoisting wheel arranged at the upper end of the shoji screen and arranged on the upper rail, and a soft-close part arranged at the upper end of the shoji screen and arranged on the upper rail integral with the hoisting wheel, wherein the upper rail is engaged with the upper frame at the underside of the upper frame and is fastened and fixed to the upper frame by fastening members.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In this specification, the term "visible direction" refers to the face direction of a glass panel in a fixture placed in an opening in a building. In the visible direction, the horizontal direction is referred to as the left-right direction. The term "visible direction" refers to the thickness direction of the glass panel (i.e., the depth direction). In this embodiment, a case where a glass panel is used as an example of a surface material will be described. The surface material is not limited to a glass panel.

[0009] As shown in Figures 1 to 3, the fitting 1 of the first embodiment is installed in an opening formed in a modular bathroom (not shown) as a building. The fitting 1 is a so-called sliding shoji screen, and as shown in Figure 1, it comprises a frame 2, an inner shoji screen 3 (shoji screen) and an outer shoji screen 4 (shoji screen) fitted into the frame 2 so that they can be opened and closed, and a bathroom ventilation structure 5. In this embodiment, the sliding shoji screen that is located on the bathroom side X1 is referred to as the inner shoji screen 3, and the shoji screen that is located on the changing room side X2 is referred to as the outer shoji screen 4. The fitting 1 can open and close the opening within the frame 2 using the inner shoji screen 3 and outer shoji screen 4.

[0010] The frame 2 is installed in an opening formed in a unit bath (not shown) as a building. Inside the unit bath, a bathroom space is formed in which a waterproof pan 11, a bathtub (not shown), etc. are installed, as shown in Figure 2. The opening of the unit bath connects the bathroom to a dressing room.

[0011] As shown in FIGS. 1 to 3, the frame body 2 is framed in a rectangular shape by an upper frame 21, a lower frame 22, and left and right vertical frames 23, 24.

[0012] As shown in Figure 2, the upper frame 21 has an upper frame bathroom-side intake 211 provided on the bathroom side X1 and an upper frame changing room-side intake 212 provided on the changing room side X2. The upper frame bathroom-side intake 211 and the upper frame changing room-side intake 212 are arranged side by side in the viewing direction and are formed into a frame shape that opens downward. The upper frame bathroom-side intake 211 is where the upper end of the inner shoji screen 3 is placed. The upper frame changing room-side intake 212 is where the upper end of the outer shoji screen 4 is placed.

[0013] 2, the lower frame 22 has a lower frame main body 221 and a lower frame slope member 222 (lower frame cover member). Both the lower frame main body 221 and the lower frame slope member 222 are formed in an elongated shape extending in the left-right direction and also extending in the projection direction.

[0014] Bathroom ventilation structure 5 is provided on lower frame 22. Bathroom ventilation structure 5 configures the gap between lower frame main body 221 and lower frame slope member 222 in lower frame 22 as ventilation passage 223, and ventilates the bathroom through ventilation passage 223. Bathroom ventilation structure 5 includes first slat 51 rotatable about pivot shaft 51a and second slat 52 rotatable about pivot shaft 52a to prevent water from flowing from the bathroom side to the dressing room side, and these are arranged in ventilation passage 223.

[0015] The inner shoji screen 3 and the outer shoji screen 4 are arranged so that they can move left and right within the frame body 2. The inner shoji screen 3 and the outer shoji screen 4 can slide left and right (horizontally) within the frame body 2. The inner shoji screen 3 and the outer shoji screen 4 are both sliding doors, and by sliding them left and right, the opening inside the frame body 2 can be opened or closed, forming what is known as a sliding shoji screen.

[0016] As shown in Figures 1 to 3, each of the inner shoji screens 3 comprises a rectangular frame body 35 formed by a long, narrow upper frame 31, a lower frame 32, a joint frame 33 (frame), and a door end frame 34 (frame), and a glass panel 36 (face material) fitted and fixed into the frame body 35. The glass panel 36 is fitted and fixed into the narrow frames (upper frame 31, lower frame 32, joint frame 33, and door end frame 34), and the inner shoji screen 3 has a sleek design.

[0017] As shown in Figures 1 to 3, each of the outer shoji screens 4 comprises a rectangular frame body 45 formed by a long, narrow upper frame 41, a lower frame 42, a joint frame 43 (frame), and a door end frame 44 (frame), and a glass panel 46 (face material) fitted and fixed into the frame body 45. The glass panel 46 is fitted and fixed into the narrow frames (upper frame 41, lower frame 42, joint frame 43, and door end frame 44), and the outer shoji screen 4 has a clean design.

[0018] Next, we will explain the mounting structure in which the hoisting wheels 37, 38 and soft-close part 61 of the inner shoji screen 3 are attached to the underside 213a of the upper frame 21 via the bathroom side upper rail 71, and the mounting structure in which the hoisting wheels 47, 48 and soft-close part 62 of the outer shoji screen 4 are attached to the underside 213a of the upper frame 21 via the changing room side upper rail 72.

[0019] As shown in Figure 4, the upper frame 21 has a hollow frame 213 formed at the top with a hollow portion extending in the forward direction, a bathroom side downward extension portion 214 extending downward from the end side of the hollow frame 213 on the bathroom side X1, and a changing room side downward extension portion 215 extending downward from the end side of the hollow frame 213 on the changing room side X2.

[0020] As shown in Figures 4 and 5, on the underside 213a of the hollow frame 213, a bathroom-side upper rail 71 is fitted and fixed to the bathroom side X1, and a dressing room-side upper rail 72 is fitted and fixed to the dressing room side X2. The bathroom-side upper rail 71 is disposed between the upper frame 21 and the inner shoji screen 3. The dressing room-side upper rail 72 is disposed between the upper frame 21 and the outer shoji screen 4.

[0021] As shown in Figure 4, inside the bathroom-side upper rail 71, the hoists 37, 38 and soft-close component 61 provided at the upper end of the inner shoji screen 3 are arranged. The soft-close component 61 is a component that constitutes a soft-close mechanism that functions to close the inner shoji screen 3 gently.

[0022] As shown in Figures 6 and 7, the hoisting wheels 37, 38 and soft-close component 61 are provided at the upper end of the inner shoji screen 3, with the hoisting wheel 37 provided on the door leading side and the hoisting wheel 38 provided on the door trailing side at the upper end of the inner shoji screen 3. The soft-close component 61 is connected to the door trailing side of the hoisting wheel 37 on the door leading side.

[0023] The soft-close component 61 is formed integrally with the hoist 37 on the door-edge side, and is formed long, extending from the hoist 37 on the door-edge side of the inner shoji screen 3 toward the door tail. A guide roller 611 is attached to the opposite side of the soft-close component 61 from the hoist 37 in the longitudinal direction. Inside the soft-close component 61, for example, cushioning members such as dampers (not shown) and components related to the soft-close mechanism are arranged.

[0024] As shown in Figure 4, inside the upper rail 72 on the changing room side, the hoists 47, 48 and the soft-close part 62 provided at the upper end of the outer screen 4 are arranged. The soft-close part 62 is a part that constitutes the soft-close mechanism that functions to close the outer screen 4 gently.

[0025] As shown in Figures 6 and 7, the hoist wheels 47, 48 and soft-close part 62 are provided at the upper end of the outer shoji screen 4, with the hoist wheel 47 provided on the door leading side and the hoist wheel 48 provided on the door trailing side at the upper end of the outer shoji screen 4. The soft-close part 62 is connected to the door trailing side of the hoist wheel 47 on the door leading side.

[0026] The soft-close component 62 is formed integrally with the hanging wheel 47 on the door tip side, and is formed long and extends from the hanging wheel 47 on the door tip side of the outer shoji screen 4 toward the door tail side. A guide roller 621 is attached to the opposite side of the soft-close component 62 from the hanging wheel 47 in the longitudinal direction. Inside the soft-close component 62, for example, cushioning members such as dampers (not shown) and components related to the soft-close mechanism are arranged.

[0027] As shown in FIG. 4, a pair of rail engagement protrusions 211a, 211b with which the bathroom-side upper rail 71 engages are provided on the bathroom side X1 of the lower surface 213a of the hollow frame 213.

[0028] The rail engagement protrusion 211a on the bathroom side X1 protrudes toward the dressing room side X2 from the bathroom side downward extension 214. The rail engagement protrusion 211b on the dressing room side X2 protrudes toward the bathroom side X1 from the lower end of a downward protrusion piece 216 that protrudes downward midway in the projection direction from the underside 213a of the hollow frame 213 of the upper frame 21.

[0029] The pair of rail engagement protrusions 211a, 211b protrude toward each other inward in the projection direction at a position spaced downward from the underside 213a of the hollow frame 213 arranged at the top of the upper frame 21 on the bathroom side (X1). An escape space K1 is formed above the rail engagement protrusion 211a on the bathroom side (X1). The escape space K1 may also be provided above the rail engagement protrusion 211b on the undressing room side (X2). The escape space K1 is a space that allows at least one of the pair of rail engagement protrusions 211a, 211b to escape when the bathroom-side upper rail 71 is engaged with the upper frame 21.

[0030] The pair of rail engagement protrusions 211a, 211b are engaged with a pair of protruding engagement pieces 717, 717 (described later) of the bathroom side upper rail 71. As a result, the bathroom side upper rail 71 is attached by engagement to the pair of rail engagement protrusions 211a, 211b on the underside 213a of the upper frame 21.

[0031] As shown in FIG. 4, a pair of rail engagement protrusions 212a, 212b with which the changing room side upper rail 72 engages are provided on the lower surface 213a of the hollow frame 213 on the changing room side X2.

[0032] The rail engagement protrusion 212a on the changing room side X2 protrudes toward the bathroom side X1 from the changing room side downward extension 215. The rail engagement protrusion 212b on the bathroom side X1 protrudes toward the changing room side X2 from the lower end of a downward protrusion piece 216 that protrudes downward halfway in the projection direction from the underside 213a of the hollow frame 213 of the upper frame 21.

[0033] The pair of rail engagement protrusions 212a, 212b protrude toward each other inward in the projection direction at a position spaced downward from the underside 213a of the hollow frame 213 arranged at the top of the upper frame 21 on the changing room side X2. An escape space K2 is formed above the rail engagement protrusion 212a on the changing room side X2. The escape space K2 may also be provided above the rail engagement protrusion 212b on the bathroom side X1. The escape space K2 is a space that allows at least one of the pair of rail engagement protrusions 212a, 212b to escape when the changing room side upper rail 72 is engaged with the upper frame 21.

[0034] The pair of rail engagement protrusions 212a, 212b engage with a pair of protruding engagement pieces 727, 727 (described later) of the changing room side upper rail 72. As a result, on the underside 213a of the upper frame 21, the changing room side upper rail 72 is attached by engagement to the pair of rail engagement protrusions 212a, 212b.

[0035] As shown in Figure 4, the bathroom-side upper rail 71 and the changing room-side upper rail 72 are arranged side by side in the projection direction on the underside 213a of the upper frame 21. The bathroom-side upper rail 71 and the changing room-side upper rail 72 are constructed as separate pieces. The bathroom-side upper rail 71 and the changing room-side upper rail 72 are fitted to the upper frame 21 on the underside 213a of the upper frame 21, and are fastened and fixed to the upper frame 21 with separate screws 701, 702 (fastening members), respectively.

[0036] As shown in Figures 5 and 6, the bathroom-side upper rail 71 is divided into multiple divided rails 711 that extend in the longitudinal direction of the upper frame 21, and the multiple divided rails 711 are arranged in the longitudinal direction. Inside the bathroom-side upper rail 71, as shown in Figures 6 and 7, the hoists 37, 38 and soft-close parts 61 that are provided at the upper end of the inner shoji screen 3 are arranged.

[0037] 4, the bathroom-side upper rail 71 has a U-shaped portion 715 that opens downward, a pair of inclined locking pieces 716, 716 formed at the lower end of the U-shaped portion 715, and a pair of protruding mating pieces 717, 717 (mating portions) that protrude from the upper end of the U-shaped portion 715 on both the bathroom side X1 and the changing room side X2. The pair of protruding mating pieces 717, 717 of the bathroom-side upper rail 71 are mated with a pair of rail mating protrusions 211a, 211b formed on the bathroom side X1 of the underside 213a of the upper frame 21.

[0038] As shown in Figures 5 and 6, the upper rail 72 on the dressing room side is divided into multiple divided rails 721 that extend in the longitudinal direction of the upper frame 21, and the multiple divided rails 721 are arranged in the longitudinal direction. As shown in Figures 6 and 7, the hoists 47, 48 and soft-close parts 62 that are provided at the upper end of the outer shoji screen 4 are arranged inside the upper rail 72 on the dressing room side.

[0039] 4, the changing room-side upper rail 72 has a U-shaped portion 725 that opens downward, a pair of inclined locking pieces 726, 726 formed at the lower end of the U-shaped portion 725, and a pair of protruding mating pieces 727, 727 (mating portions) that protrude from the upper end of the U-shaped portion 725 on both the bathroom side X1 and the changing room side X2. The pair of protruding mating pieces 727, 727 of the changing room-side upper rail 72 are mated with a pair of rail mating protrusions 212a, 212b formed on the changing room side X2 of the underside 213a of the upper frame 21.

[0040] The case where the upper rails (bathroom-side upper rail 71, changing room-side upper rail 72) are fitted to the underside 213a of the upper frame 21 will be described with reference to Figure 8. While Figure 8 shows the changing room-side upper rail 72, the same applies to the bathroom-side upper rail 71.

[0041] When fitting the upper rails (bathroom side upper rail 71, changing room side upper rail 72) to the underside 213a of the upper frame 21, as shown in Figure 8, the upper rails (bathroom side upper rail 71, changing room side upper rail 72) are tilted relative to the forward direction so that the escape spaces K1, K2 are facing upward, and the protruding engagement pieces 717, 727 on the escape spaces K1, K2 side are first inserted into the escape spaces K1, K2 and released, and the upper rails (bathroom side upper rail 71, changing room side upper rail 72) are then horizontally moved to the side opposite the escape spaces K1, K2, so that the protruding engagement pieces 717, 727 on the side opposite the escape spaces K1, K2 are fitted to the rail engagement protrusions 211a, 212a. This causes a pair of protruding mating pieces 717, 727 of the upper rails (bathroom side upper rail 71, changing room side upper rail 72) to be mated with rail mating protrusions 211a, 211b, 212a, 212b of upper frame 21.

[0042] Then, after engaging a pair of protruding mating pieces 717, 727 of the upper rails (bathroom side upper rail 71, changing room side upper rail 72) with the rail mating protrusions 211a, 211b, 212a, 212b of the upper frame 21, the bathroom side upper rail 71 and the changing room side upper rail 72 are fastened and fixed to the upper frame 21 using screws 701, 702, as shown in Figure 4.

[0043] Next, we will explain the procedure for replacing the hoists 47, 48 and the soft-close part 62 of the outer shoji screen 4. The procedure for replacing the hoists 37, 38 and the soft-close part 61 of the inner shoji screen 3 is similar. The explanation for the inner shoji screen 3 can be derived from the explanation for the outer shoji screen 4.

[0044] To remove the hoist wheels 47, 48 and the soft-close part 62 of the outer screen 4 from the upper frame 21, the dressing room-side upper rail 72, on which the integrally constructed hoist wheel 47, soft-close part 62, and hoist wheel 48 are mounted, is removed from the upper frame 21. First, from the state shown in FIG. 4, the integrally constructed hoist wheel 47, soft-close part 62, and hoist wheel 48 are moved left and right from the point where they are fastened by the screw 702, and the screw 702 fastening the upper frame 21 to the dressing room-side upper rail 72 is removed. Next, the dressing room-side upper rail 72 is moved horizontally toward the dressing room side X2 and tilted so that the protruding mating piece 727 on the bathroom side X1 faces downward, allowing the dressing room-side upper rail 72 to be removed from the upper frame 21, as shown in FIG. 8.

[0045] Next, the changing room side upper rail 72, on which the hoist 47, soft-close part 62, and hoist 48, which are integrally formed, are arranged, is attached to the upper frame 21. In this case, first, with the hoist 47 and soft-close part 62, which are integrally formed, arranged on the changing room side upper rail 72, the changing room side upper rail 72 is mated to the upper frame 21 on the underside 213a of the upper frame 21 (mating process).

[0046] 8, the changing room-side upper rail 72 is tilted relative to the forward direction so that the relief space K2 side faces upward, and the protruding mating piece 727 on the relief space K2 side is temporarily inserted into the relief space K2 and released, and the changing room-side upper rail 72 is then horizontally moved toward the bathroom side X1, thereby mating the protruding mating piece 727 on the bathroom side X1 with the rail mating protrusion 212b. This allows the pair of protruding mating pieces 727 of the changing room-side upper rail 72 to be mated with the rail mating protrusions 212a, 212b of the upper frame 21 for easy installation.

[0047] Next, the changing room side upper rail 72 is fastened and fixed to the upper frame 21 with the screws 702 (fixing process). Specifically, the hoists 47, 48 and the soft-close parts 62 are moved left and right from the points where they are fastened with the screws 702, and the screws 702 are moved from the lower side of the changing room side upper rail 72 to the upper side, so that the screws 702 pass through the changing room side upper rail 72 and the upper frame 21, and the changing room side upper rail 72 is fastened and fixed to the upper frame 21 with the screws 702, as shown in FIG.

[0048] Here, because the upper rail 72 on the changing room side is divided into multiple divided rails 712 in the longitudinal direction, it is only necessary to remove and replace the divided rail 712 in the section where the soft-close device 61 is located. Therefore, the hoist 47 and soft-close device 62, which are configured as an integrated unit, can be easily replaced.

[0049] According to this embodiment, the following effects are achieved: The fitting 1 of this embodiment comprises a frame body 2 having an upper frame 21, an inner shoji screen 3 and an outer shoji screen 4 arranged so as to be movable laterally within the frame body 2, upper rails (bathroom-side upper rail 71, changing room-side upper rail 72) fixed to the upper frame 21 on its underside, hoists 37, 47 provided at the upper ends of the inner shoji screen 3 and the outer shoji screen 4 and arranged on the upper rails (bathroom-side upper rail 71, changing room-side upper rail 72), and soft-close components 61, 62 provided at the upper ends of the inner shoji screen 3 and the outer shoji screen 4 and arranged on the upper rails (bathroom-side upper rail 71, changing room-side upper rail 72) as one unit with the hoists 37, 47, the upper rails (bathroom-side upper rail 71, changing room-side upper rail 72) engaging with the upper frame 21 on its underside 213a and fastened to the upper frame 21 with screws 701, 702.

[0050] This allows the integrally constructed hoist wheels 37, 47 and soft-close components 61, 62 to be easily attached to the upper rails (bathroom-side upper rail 71, changing room-side upper rail 72). Furthermore, the upper rails (bathroom-side upper rail 71, changing room-side upper rail 72) are fitted to the upper frame 21 at the lower surface 213a of the upper frame 21 and are fastened and fixed to the upper frame 21 with screws 701, 702, so the upper rails (bathroom-side upper rail 71, changing room-side upper rail 72) can be firmly fixed to the lower surface 213a of the upper frame 21.

[0051] Furthermore, in this embodiment, the upper rails (bathroom-side upper rail 71, changing room-side upper rail 72) are configured with multiple divided rails 711, 721 aligned longitudinally and extending in the longitudinal direction of the upper frame 21. Because the upper rails (bathroom-side upper rail 71, changing room-side upper rail 72) are divided into multiple divided rails 711, 712 in the longitudinal direction, it is only necessary to remove and replace the divided rails 711, 712 in the portions where the soft-close components 61, 62 are located. This makes the replacement process easier, as it is not necessary to replace the entire upper rail (bathroom-side upper rail 71, changing room-side upper rail 72).

[0052] Furthermore, in this embodiment, the bathroom-side upper rail 71 and the changing room-side upper rail 72 are constructed as separate pieces, and are fastened to the upper frame 21 by separate screws 701, 702, respectively. Therefore, when it is necessary to replace either the bathroom-side upper rail 71 or the changing room-side upper rail 72, it is possible to replace only either the bathroom-side upper rail 71 or the changing room-side upper rail 72, without having to replace both the bathroom-side upper rail 71 and the changing room-side upper rail 72. Therefore, the replacement work is easy because it is not necessary to replace all of the upper rails (bathroom-side upper rail 71, changing room-side upper rail 72).

[0053] Furthermore, the construction method for the fixture 1 of this embodiment includes the steps of fitting the upper rails (bathroom side upper rail 71, dressing room side upper rail 72) to the upper frame 21 on the underside 213a of the upper frame 21 with the hoisting wheels 37, 47 and soft-close components 61, 62 integrally formed on the upper rails arranged thereon, and fastening and fixing the upper rails (bathroom side upper rail 71, dressing room side upper rail 72) to the upper frame 21 with screws 701, 702. This allows the hoisting wheels 37, 47 and soft-close components 61, 62 integrally formed to be easily attached to the upper rails (bathroom side upper rail 71, dressing room side upper rail 72). In addition, the upper rails (bathroom side upper rail 71, changing room side upper rail 72) are engaged with the upper frame 21 on the underside 213a of the upper frame 21 and are fastened to the upper frame 21 with screws 701, 702, so that the upper rails (bathroom side upper rail 71, changing room side upper rail 72) can be firmly fixed to the underside 213a of the upper frame 21.

[0054] Next, a second embodiment will be described. In the description of the second embodiment, the description of the same configuration as the first embodiment will be omitted or simplified as appropriate. For the configuration not described in the second embodiment, the description of the first embodiment will be used.

[0055] The second embodiment differs from the first embodiment mainly in that, whereas in the first embodiment the bathroom side upper rail 71 and the changing room side upper rail 72 are formed separately, the second embodiment is provided with an integrated upper rail 73 which combines the bathroom side upper rail 71 and the changing room side upper rail 72, and in that the upper rail 73 is fixed with a common screw 703 (fastening member).

[0056] As shown in Figure 9, the fitting 1 of the second embodiment comprises an upper frame 21A and an integrated upper rail 73. The integrated upper rail 73 is formed by connecting the bathroom side upper rail 71 and the changing room side upper rail 72 of the first embodiment via an intermediate connector 731. The integrated upper rail 73 has a pair of protruding joint pieces 737 formed on its upper end that protrude on both the bathroom side X1 and the changing room side X2.

[0057] In the upper frame 21A, the lower surface 213a of the hollow frame 213 does not have the downward protruding piece 216 shown in Figure 4 of the first embodiment, the rail mating protrusion 211b on the changing room side X2 of the bathroom side upper rail 71, and the rail mating protrusion 212b on the bathroom side X1 of the changing room side upper rail 72, and the middle portion of the lower surface 213a of the hollow frame 213 in the prospective direction is formed flat.

[0058] By engaging the pair of protruding engagement pieces 737 with the rail engagement protrusions 211a, 212a of the upper frame 21A, the integral upper rail 73 is attached to the pair of rail engagement protrusions 211a, 212a of the upper frame 21A by engagement.

[0059] The integrated upper rail 73, which is attached to the lower surface 213a of the upper frame 21A by fitting, is fastened and fixed to the upper frame 21A with a common screw 703 (fastening member). When fastening with the screw 703, the screw 703 is moved from the lower side to the upper side of the integrated upper rail 73 at the middle position of the integrated upper rail 73 in the projection direction, so that the screw 703 penetrates the integrated upper rail 73. In this way, the screw 703 fastens and fixes the integrated upper rail 73 to the upper frame 21A.

[0060] According to the second embodiment, the integrally constructed upper rails 73 (bathroom-side upper rail 71 and changing room-side upper rail 72) are fitted to the upper frame 21A and fastened to the upper frame 21A with common screws 703. This allows the integrally constructed upper rails 73 (bathroom-side upper rail 71 and changing room-side upper rail 72) to be fitted and fixed to the upper frame 21A at once, facilitating the fastening and removal operations.

[0061] Next, a third embodiment will be described. In the description of the third embodiment, the description of the same configuration as the third embodiment will be omitted or simplified as appropriate. The description of the first embodiment can be used for the configuration not described in the third embodiment.

[0062] The main difference between the fitting structure of the bathroom side upper rail 71A and the changing room side upper rail 72A in the third embodiment is the fitting structure of the bathroom side upper rail 71 and the changing room side upper rail 72 in the first embodiment.

[0064] The pair of bathroom-side L-shaped joints 217, 217 each protrude downward from the underside 213a of the hollow frame 213 of the upper frame 21B and are formed in an L shape that opens on the bathroom side X1. The pair of changing room-side L-shaped joints 218, 218 each protrude downward from the underside 213a of the hollow frame 213 of the upper frame 21B and are also formed in an L shape that opens on the changing room side X2.

[0065] The bathroom-side upper rail 71A has a pair of bathroom-side rail L-shaped joints 718, 718 that join with a pair of bathroom-side L-shaped joints 217, 217 of the upper frame 21B. The pair of bathroom-side rail L-shaped joints 718, 718 protrude upward from the bathroom-side upper rail 71A and are formed in an L shape that opens to the dressing room side X2.

[0066] When attaching the bathroom side upper rail 71A to the upper frame 21B, the pair of bathroom side rail L-shaped joints 718, 718 of the bathroom side upper rail 71A can be inserted into the insertion space S1 on the bathroom side X1 of the pair of bathroom side L-shaped joints 217, 217 formed on the underside 213a of the upper frame 21B and moved horizontally to the changing room side X2, thereby attaching the pair of bathroom side rail L-shaped joints 718, 718 of the bathroom side upper rail 71A to the pair of bathroom side L-shaped joints 217, 217 of the upper frame 21B.

[0067] The changing room side upper rail 72A has a pair of changing room side rail L-shaped joints 719, 719 that join with a pair of changing room side L-shaped joints 218, 218 of the upper frame 21B. The pair of bathroom side rail L-shaped joints 718, 718 protrude upward from the changing room side upper rail 72A and are formed in an L shape that opens to the bathroom side X1.

[0068] When attaching the changing room side upper rail 712A to the upper frame 21B by fitting it to the upper frame 21B, the pair of changing room side rail L-shaped joints 719, 719 of the changing room side upper rail 72A can be inserted into the insertion space S2 on the changing room side X2 of the pair of changing room side L-shaped joints 218, 218 formed on the underside 213a of the upper frame 21B and moved horizontally to the bathroom side X1, thereby attaching the pair of changing room side rail L-shaped joints 719, 719 of the changing room side upper rail 72A by fitting them to the pair of changing room side L-shaped joints 218, 218 formed on the underside 213a of the upper frame 21B.

[0069] After the bathroom-side upper rail 71A and the changing room-side upper rail 72A are fitted and attached to the upper frame 21B, the bathroom-side upper rail 71A and the changing room-side upper rail 72A are fastened and fixed to the upper frame 21B with screws 701, 702 (fastening members) in the same manner as in the first embodiment. The third embodiment can achieve the same effects as the first embodiment.
