In this embodiment, the sliding shoji screen arranged on the bathroom side X1 is referred to as the inner shoji screen 3, and the shoji screen arranged 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 the outer shoji screen 4. In this embodiment, the shoji screen arranged on the bathroom side is referred to as the inner shoji screen 3 (on the right side as viewed from the bathroom side), and the shoji screen arranged on the changing room side is referred to as the outer shoji screen 4 (on the left side as viewed from the bathroom side), but this is not limited thereto. The shoji screen arranged on the bathroom side may be referred to as the inner shoji screen 3 (on the left side as viewed from the bathroom side), and the shoji screen arranged on the changing room side may be referred to as the outer shoji screen 4 (on the right side as viewed from the bathroom side).

[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 Figures 2 and 3. The opening of the unit bath connects the bathroom to a dressing room.

[0011] As shown in Figures 1 to 4, 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. The upper frame 21 is formed in an elongated shape extending in the left-right direction at the upper part of the frame body 2.

The left and right vertical frames 23, 24 extend in the up-down direction at both left-right end portions of the upper frame 21 and the lower frame 22.

[0012] The inner shoji screen 3 and the outer shoji screen 4 are arranged so that they 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.

[0013] As shown in Figures 1, 2 and 4, each of the inner shoji screens 3 comprises a rectangular frame body 35 made up of 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.

[0014] As shown in Figure 2, the lower frame 32 of the inner shoji screen 3 has a lower frame body 321 formed with a hollow structure having a hollow portion, and a lower end protrusion 322 (protrusion) protruding downward from the underside of the lower frame body 321. The lower end protrusion 322 comes into contact with the inner shoji screen lower gasket 721 (described later).

[0015] The lower end protrusion 322 is provided at the lower end of the inner shoji screen 3. The lower end protrusion 322 is formed to extend in the left-right direction and protrudes downward from the underside of the lower frame body 321 at a position inside both ends of the lower frame body 321 in the projection direction.

[0016] In this embodiment, the lower end protrusion 322 protrudes downward from the underside of the stile body 321 at a position closer to the outer shoji screen 4 in the projection direction of the underside of the stile body 321. Specifically, the lower end protrusion 322 is formed at a position on the bathroom side X1 a predetermined distance from the face 321b of the end of the stile body 321 on the changing room side X2 in the projection direction of the underside of the stile body 321, and at a position closer to the outer shoji screen 4 (changing room side X2) than the center position between the face 321a of the end of the stile body 321 on the bathroom side X1 and the face 321b of the end of the stile body 321 on the changing room side X2.

[0017] As shown in Figures 1, 3 and 4, the outer shoji screen 4 is comprised of 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] As shown in Figure 3, the lower frame 42 of the outer shoji screen 4 has a lower frame body 421 formed with a hollow structure having a hollow portion, and a lower end protrusion 422 (protrusion) protruding downward from the underside of the lower frame body 421. The lower end protrusion 422 comes into contact with the outer shoji screen lower gasket 722 (described later).

[0019] The lower end protrusion 422 is provided at the lower end of the outer shoji screen 4. The lower end protrusion 422 is formed to extend in the left-right direction and protrudes downward from the underside of the lower frame body 421 at a position inside both ends of the lower frame body 421 in the prospective direction.

[0020] In this embodiment, the lower end protrusion 422 protrudes downward from the underside of the stile body 421 at a position closer to the inner shoji screen 3 in the projection direction of the underside of the stile body 421. Specifically, the lower end protrusion 422 is formed at a position on the changing room side X2 a predetermined distance from the face 421a of the end of the stile body 421 on the bathroom side X1 in the projection direction of the underside of the stile body 421, and at a position closer to the inner shoji screen 3 (bathroom side X1) than the center position between the face 421a of the end of the stile body 421 on the bathroom side X1 and the face 421b of the end of the stile body 421 on the changing room side X2.

[0021] 2 and 3, the upper frame 21 has an upper frame bathroom-side inlet 211 provided on the bathroom side X1 and an upper frame changing room-side inlet 212 provided on the changing room side X2. The upper frame bathroom-side inlet 211 and the upper frame changing room-side inlet 212 are arranged side by side in the viewing direction and are formed in a frame shape that opens downward.

[0022] As shown in Figure 2, the upper end of the upper frame bathroom-side intake section 211 is provided with a pair of bathroom-side rail holders 211a that are positioned on the bathroom side X1. A bathroom-side upper rail 61 is attached to the pair of bathroom-side rail holders 211a. The bathroom-side upper rail 61 is formed in a U-shape that opens downward. A hoist 37, which is provided at the upper end of the upper frame 31 of the inner shoji screen 3, is attached to the bathroom-side upper rail 61.

[0023] As shown in Figure 2, the hoist 37 has a wheel portion 371, a rotating shaft portion 372, and an upper frame mounting portion 373. The wheel portion 371 is arranged inside the bathroom side upper rail 61 so that it can move left and right. The rotating shaft portion 372 extends downward from the lower end of the wheel portion 371. The upper frame mounting portion 373 is attached to the upper end of the upper frame 31 of the inner shoji screen 3.

[0024] As shown in Figure 3, a pair of changing room side rail holders 212a are provided at the upper end of the upper frame changing room side intake section 212, which are positioned on the changing room side X2. A changing room side upper rail 62 is attached to the pair of changing room side rail holders 212a. The changing room side upper rail 62 is formed in a U-shape that opens downward. A hoist 47, which is attached to the upper end of the upper frame 41 of the outer shoji screen 4, is arranged on the changing room side upper rail 62 so that it can move left and right.

[0025] As shown in Figure 3, the hoist 47 has a wheel portion 471, a rotating shaft portion 472, and an upper frame mounting portion 473. The wheel portion 471 is arranged inside the upper rail 62 on the dressing room side so that it can move left and right. The rotating shaft portion 472 extends downward from the lower end of the wheel portion 471. The upper frame mounting portion 473 is attached to the upper end of the upper frame 41 of the outer shoji screen 4.

[0026] 2 and 3, 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.

[0027] 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.

[0028] A downwardly recessed guide recess 224 is formed on the upper surface of the lower frame slope member 222 midway in the viewing direction. The guide recess 224 is located below the inner shoji screen 3 and the outer shoji screen 4. The lower end protrusion 322 (see Figure 2) of the inner shoji screen 3 and the lower end protrusion 422 (see Figure 3) of the outer shoji screen 4 are located in the guide recess 224. The guide recess 224 guides the lower ends of the inner shoji screen 3 and the outer shoji screen 4, which can slide.

[0029] The vertical frame 23 is formed on one side of the door / window fixture 1 in the left-right direction (the left side in Fig. 1, the right side in Fig. 4), extending in the projection direction as shown in Fig. 4. The vertical frame 23 is provided with a recess 231 that opens inward in the left-right direction at a position closer to the changing room side X2 in the projection direction. The recess 231 accommodates the door edge frame 44 of the outer shoji screen 4 when the outer shoji screen 4 is in the closed position.

[0030] The vertical frame 24 is formed on the other left-right side of the fitting 1 (the right side in Fig. 1, the left side in Fig. 4) and extends in the projection direction as shown in Fig. 4. The vertical frame 24 is provided with a recess 241 that opens inward in the left-right direction at a position closer to the bathroom side X1 in the projection direction. The recess 241 accommodates the door stile 34 of the inner shoji screen 3 when the inner shoji screen 3 is in the closed position.

[0031] Next, we will explain the water-stopping structure of the inner shoji 3 and outer shoji 4 arranged within the frame body 2. As shown in Fig. 5, the upper frame 21, lower frame 22, and vertical frames 23 and 24 are each provided with water-stopping gaskets (inner shoji upper gasket 711, outer shoji upper gasket 712, inner shoji lower gasket 721, outer shoji lower gasket 722, vertical gaskets 731 and 732). Also, as shown in Fig. 4, the joint frame 33 of the inner shoji 3 and the joint frame 43 of the outer shoji 4 are each provided with water-stopping gaskets (inner shoji joint frame gasket 751, outer shoji joint frame gasket 752).

[0032] As shown in Figures 2 and 3, the inner screen upper gasket 711 and the outer screen upper gasket 712 are provided on the upper frame 21.

[0033] As shown in Figure 2, the inner shoji upper gasket 711 is attached to a gasket mounting groove 611 formed on the underside of the lower end of the U-shaped changing room side X2 of the bathroom side upper rail 61 below the upper frame 21. The gasket mounting groove 611 is formed as a C-shaped groove whose cross section opens downward.

[0034] As shown in Figures 5 and 6, the inner shoji upper packing 711 is arranged to extend in the left-right direction only within the left-right range of the inner shoji 3 when it is in the closed position. The inner shoji upper packing 711 is not provided anywhere other than within the left-right range of the inner shoji 3 when it is in the closed position.

[0035] As shown in Figure 2, the inner shoji upper packing 711 has a fin portion 711a extending downward from the underside of the lower end of the bathroom-side upper rail 61 on the changing room side X2, and the lower end of the fin portion 711a contacts the side surface 311 on the changing room side X2 at the upper end of the upper frame 31 of the inner shoji 3. Because the inner shoji upper packing 711 contacts the side surface 311 on the changing room side X2 at the upper end of the upper frame 31, it can accommodate variations in the vertical position of the upper frame 31, and the inner shoji upper packing 711 contacts the side surface 311 on the changing room side X2 of the upper frame 31 to ensure watertightness.

[0036] As shown in Figure 3, the outer screen upper gasket 712 is attached to a gasket mounting groove 621 formed on the underside of the lower end of the U-shaped bathroom side X1 of the dressing room side upper rail 62 below the upper frame 21. The gasket mounting groove 621 is formed as a C-shaped groove whose cross section opens downward.

[0037] The outer screen upper gasket 712 is arranged to extend left and right only within the left and right range of the outer screen 4 when it is in the closed position, as shown in Figures 5 and 6. The outer screen upper gasket 712 is not provided anywhere other than the left and right range of the outer screen 4 when it is in the closed position.

[0038] As shown in Figure 3, the outer screen upper gasket 712 has a fin portion 712a extending downward from the underside of the lower end of the bathroom side X1 of the dressing room side upper rail 62, and the lower end of the fin portion 712a contacts the side surface 411 of the bathroom side X1 at the upper end of the upper frame 41 of the outer screen 4. Because the outer screen upper gasket 712 contacts the side surface 411 of the bathroom side X1 at the upper end of the upper frame 41 of the outer screen 4, it can accommodate variations in the vertical position of the upper frame 41, and the outer screen upper gasket 712 contacts the side surface 411 of the bathroom side X1 of the upper frame 41 to ensure watertightness.

[0039] The inner shoji upper gasket 711 and the outer shoji upper gasket 712 are arranged to extend in the left-right direction, with their positions in the projection direction different and offset from each other, as shown in Figure 6. Above the joint portion 15 (see Figure 4) of the inner shoji 3 and outer shoji 4, the upper frame 21 is provided with an upper frame side water stop component 713. As shown in Figures 5 and 6, the upper frame side water stop component 713 is arranged between the inner shoji upper gasket 711 and the outer shoji upper gasket 712.

[0040] 6, the upper frame side water-stopping component 713 has a plurality of plate-like pieces 713a that protrude downward. The surface direction of the plurality of plate-like pieces 713a is formed along the projection direction, and the plate-like pieces 713a are arranged in parallel at predetermined intervals in the longitudinal direction of the upper frame 21.

[0041] The multiple plate-like pieces 713a have a height that allows them to overlap the upper end of the joint frame 33 of the inner shoji screen 3 and the upper end of the joint frame 43 of the outer shoji screen 4 when the inner shoji screen 3 and the outer shoji screen 4 are in the closed position. Therefore, the plate-like pieces 713a come into contact with the upper end of the joint frame 33 of the inner shoji screen 3 and the upper end of the joint frame 43 of the outer shoji screen 4 as they move open and closed.

[0042] At this time, the plate-like piece 713a elastically deforms so as to fall along the longitudinal direction of the upper frame 21, sealing the gap between the joining frame 33 of the inner shoji screen 3 and the joining frame 43 of the outer shoji screen 4, which are positioned in the closed position, ensuring airtightness and watertightness. As a result, when the inner shoji screen 3 and the outer shoji screen 4 are positioned in the closed position, even if water is sprayed from a shower at the joining portion 15 (see Figure 4), water running sideways can be blocked. Therefore, the upper frame side water stop component 713 can reduce water running sideways at the joining portion 15 (see Figure 4) and leaking into the changing room side X2.

[0043] As described above, by providing the inner shoji upper gasket 711 and the outer shoji upper gasket 712 on the upper frame 21, water-stopping performance can be ensured when the inner shoji 3 and outer shoji 4 are in the closed position. Furthermore, since the inner shoji upper gasket 711 is arranged to extend left and right only within the left and right range of the inner shoji 3 when it is in the closed position, the area that comes into contact with the inner shoji upper gasket 711 decreases as the inner shoji 3 opens, thereby reducing operating resistance. Furthermore, since the outer shoji upper gasket 712 is arranged to extend left and right only within the left and right range of the outer shoji 4 when it is in the closed position, the area that comes into contact with the outer shoji upper gasket 712 decreases as the outer shoji 4 opens, thereby reducing operating resistance. Therefore, the impact of contact resistance between the inner shoji upper gasket 711 and the outer shoji upper gasket 712 on the opening and closing operation of the inner shoji 3 and outer shoji 4 can be reduced.

[0044] As shown in Figures 2, 3 and 7, the inner sash lower gasket 721 (first watertight gasket, watertight gasket) and the outer sash lower gasket 722 (second watertight gasket, watertight gasket) are provided in the lower frame 22. The inner sash lower gasket 721 and the outer sash lower gasket 722 are attached to the gasket placement groove 225 formed on the upper surface of the bottom 224a of the guide recess 224 of the lower frame 22, as shown in Figures 2 and 3.

[0045] As shown in Figures 2 and 3, the gasket placement groove 225 is formed as a C-shaped groove that opens upward, and extends in the left-right direction between the inner shoji screen 3 and the outer shoji screen 4 on the upper surface of the bottom 224a of the guide recess 224.

[0046] The packing arrangement groove 225 is formed to extend in the left-right direction, as shown in Fig. 8. In this embodiment, the packing arrangement groove 225 is formed such that a plurality of grooves are arranged on a straight line extending in the left-right direction with gaps in between and at the same position in the prospective direction, as shown in Fig. 8. However, the present invention is not limited to this, and the packing arrangement groove 225 may be formed by a single groove extending continuously in the left-right direction.

[0047] As shown in Figures 2 and 3, the gasket placement groove 225 is positioned in the forward direction at a position between the position where the lower end protrusion 322 at the lower end of the inner shoji screen 3 is provided and the position where the lower end protrusion 422 at the lower end of the outer shoji screen 4 is provided.

[0048] As shown in Figure 8, an inner screen lower gasket 721 is attached to the gasket placement groove 225 in the area where the inner screen 3 is in the closed position, and an outer screen lower gasket 722 is attached to the area where the outer screen 4 is in the closed position.

[0049] The inner shoji lower packing 721 is arranged to extend in the left-right direction only within the left-right range of the inner shoji 3 when it is in the closed position, as shown in Figures 7 and 8. The inner shoji lower packing 721 is not provided anywhere other than within the left-right range of the inner shoji 3 when it is in the closed position.

[0050] As shown in Figure 2, the inner shoji lower gasket 721 has a fin portion 721a that protrudes from the gasket placement groove 225 toward the bathroom side X1. The tip of the fin portion 721a protrudes toward the bathroom side X1 and contacts the lower end protrusion 322 of the inner shoji 3. The upper surface of the fin portion 721a is formed with an upper surface inclined portion 721b (inclined portion) that slopes downward from the tip side of the fin portion 721a toward the opposite side. In this embodiment, the inclined portion 721b slopes downward from the bathroom side X1 toward the changing room side X2.

[0051] The outer screen lower gasket 722 is arranged to extend left and right only within the left and right range of the outer screen 4 when it is in the closed position, as shown in Figures 7 and 8. The outer screen lower gasket 722 is not provided anywhere other than the left and right range of the outer screen 4 when it is in the closed position.

[0052] As shown in Figure 3, the outer screen lower gasket 722 has a fin portion 722a that protrudes from the gasket placement groove 225 toward the changing room side X2. The tip of the fin portion 722a protrudes toward the changing room side X2 and contacts the lower end protrusion 422 of the outer screen 4. On the upper surface of the fin portion 722a, an upper surface inclined portion 722b (inclined portion) is formed that slopes downward from the tip side of the fin portion 722a toward the opposite side. In this embodiment, the upper surface inclined portion 722b slopes downward from the changing room side X2 toward the bathroom side X1.

[0053] As shown in Figures 7 and 8, the inner shoji lower gasket 721 and the outer shoji lower gasket 722 are arranged to extend in the left-right direction, with their positions in the projection direction different and offset from each other. Below the joint portion 15 (see Figure 4) of the inner shoji 3 and the outer shoji 4, a frame-side water-stopping component 723 (water-stopping component) is provided on the frame 22. The frame-side water-stopping component 723 is arranged between the inner shoji lower gasket 721 and the outer shoji lower gasket 722.

[0054] 7, the lower frame side water-stopping component 723 has a plurality of plate-like pieces 723a that protrude upward. The surface direction of the plurality of plate-like pieces 723a is formed along the projection direction, and the plate-like pieces 723a are arranged in parallel at predetermined intervals in the longitudinal direction of the lower frame 22.

[0055] The multiple plate-like pieces 723a have a height that allows them to overlap the lower end of the joint frame 33 of the inner shoji screen 3 and the lower end of the joint frame 43 of the outer shoji screen 4 when the inner shoji screen 3 and the outer shoji screen 4 are in the closed position. Therefore, the plate-like pieces 723a come into contact with the lower end of the joint frame 33 of the inner shoji screen 3 and the lower end of the joint frame 43 of the outer shoji screen 4 as they move open and closed.

[0056] At this time, the plate-like piece 723a elastically deforms so as to fall along the longitudinal direction of the lower frame 22, sealing the gap between the joining frame 33 of the inner shoji screen 3 and the joining frame 43 of the outer shoji screen 4, which are positioned in the closed position, ensuring airtightness and watertightness. As a result, when the inner shoji screen 3 and the outer shoji screen 4 are positioned in the closed position, even if water is sprayed from a shower at the joining portion 15 (see Figure 4), water running sideways can be blocked. Therefore, the lower frame side water stop component 723 can reduce water running sideways at the joining portion 15 (see Figure 4) and leaking into the changing room side X2.

[0057] As described above, by providing the inner shoji lower gasket 721 and the outer shoji lower gasket 722 on the lower frame 22, water-stopping performance can be ensured when the inner shoji 3 and the outer shoji 4 are in the closed position. Furthermore, since the inner shoji lower gasket 721 is arranged to extend left and right only within the left and right range of the inner shoji 3 when it is in the closed position, the area that comes into contact with the inner shoji lower gasket 721 decreases as the inner shoji 3 opens, thereby reducing operating resistance. Furthermore, since the outer shoji lower gasket 722 is arranged to extend left and right only within the left and right range of the outer shoji 4 when it is in the closed position, the area that comes into contact with the outer shoji lower gasket 722 decreases as the outer shoji 4 opens, thereby reducing operating resistance. Therefore, the impact of contact resistance between the inner shoji lower gasket 721 and the outer shoji lower gasket 722 on the opening and closing operation of the inner shoji 3 and the outer shoji 4 can be reduced.

[0058] As shown in FIG. 4, the vertical packings 731 and 732 are provided on the vertical frames 23 and 24.

[0059] As shown in Figure 4, the vertical gasket 731 is attached to a gasket placement groove 235 formed on a surface 232 facing the changing room side X2, which is formed on the bathroom side X1 of the recess 231 of the vertical frame 23. The gasket placement groove 235 is formed as a C-shaped groove that opens toward the changing room side X2 and extends in the vertical direction.

[0060] The vertical gasket 731 has a fin portion 731a that protrudes from the bathroom side X1 surface 232 of the recess 231 of the vertical frame 23 toward the changing room side X2, and the tip of the fin portion 731a contacts the bathroom side X1 surface of the door frame 44 of the outer shoji screen 4.

[0061] As shown in Figure 6, at the top of the vertical gasket 731 and the end of the outer screen upper gasket 712 on the vertical frame 23 side, the vertical gasket 731 and the outer screen upper gasket 712 are arranged at different positions in the projection direction. The vertical gasket 731 and the outer screen upper gasket 712 are arranged so that the fin portion 731a of the vertical gasket 731 and the fin portion 712a of the outer screen upper gasket 712 are in contact with each other, with the vertical gasket 731 being arranged on the bathroom side X1 and the outer screen upper gasket 712 being arranged on the changing room side X2.

[0062] As shown in Figure 7, an end water-stopping part 741 is arranged between the lower end of the vertical packing 731 and the end of the outer shoji lower packing 722 on the vertical frame 23 side. The end water-stopping part 741 can stop water from flowing between the lower end of the packing 731 and the end of the outer shoji lower packing 722 on the vertical frame 23 side.

[0063] 4, the vertical gasket 732 is attached to a gasket placement groove 245 formed on a surface 242 facing the bathroom side X1, which is formed on the changing room side X2 of the recess 241 of the vertical frame 24. The gasket placement groove 245 is formed as a C-shaped groove that opens toward the bathroom side X1 and extends in the vertical direction.

[0064] The vertical gasket 732 has a fin portion 732a that protrudes from the surface 242 on the changing room side X2 of the recess 241 of the vertical frame 24 toward the bathroom side X1, and the tip of the fin portion 732a contacts the surface on the changing room side X2 of the door frame 34 of the inner shoji screen 3.

[0065] As shown in Figure 6, the vertical gasket 732 and the inner shoji upper gasket 711 are arranged at different positions in the projection direction at the top of the vertical gasket 732 and the end of the inner shoji upper gasket 711 on the vertical frame 24 side. The vertical gasket 732 and the inner shoji upper gasket 711 are arranged so that the fin portion 732a of the vertical gasket 732 and the fin portion 711a of the inner shoji upper gasket 711 are in contact with each other, with the vertical gasket 732 arranged on the changing room side X2 and the inner shoji upper gasket 711 arranged on the bathroom side X1.

[0066] As shown in Figure 7, an end water-stopping part 742 is arranged between the lower end of the vertical gasket 732 and the end of the inner shoji lower gasket 721 on the vertical frame 24 side. The end water-stopping part 742 can stop water from flowing between the lower end of the vertical gasket 732 and the end of the inner shoji lower gasket 721 on the vertical frame 24 side.

[0067] As shown in Figure 4, at the joint portion 15 of the inner shoji screen 3 and the outer shoji screen 4, an inner shoji screen joint frame gasket 751 and an outer shoji screen joint frame gasket 752 are arranged between the joint frame 33 of the inner shoji screen 3 and the joint frame 43 of the outer shoji screen 4.

[0068] The inner shoji door joint frame gasket 751 is attached to a gasket placement groove 331 formed on the surface of the inner shoji door joint frame 33 on the changing room side X2. The gasket placement groove 331 is located on the outside in the left-right direction of the surface of the inner shoji door joint frame 33 on the changing room side X2, and extends in the vertical direction. The gasket placement groove 331 is formed in a groove shape that opens in a C shape towards the changing room side X2.

[0069] The inner shoji door joint frame gasket 751 is formed to extend in the vertical direction, and contacts the bathroom side X1 surface of the joint frame 43 of the outer shoji door 4 at the joint part 15 of the inner shoji door 3 and the outer shoji door 4. The upper end of the inner shoji door joint frame gasket 751 contacts the part of the upper frame side water stop part 713 (see Figure 5) on the inner shoji upper side gasket 711 side, and the lower end contacts the part of the lower frame side water stop part 723 (see Figure 5) on the inner shoji lower side gasket 721 side.

[0070] The outer shoji door joint frame gasket 752 is attached to a gasket placement groove 431 formed on the bathroom side X1 surface of the joint frame 43 of the outer shoji door 4. The gasket placement groove 431 is positioned on the left-right outer side of the bathroom side X1 surface of the joint frame 43 of the outer shoji door 4 and extends in the vertical direction. The gasket placement groove 431 is formed in a groove shape that opens in a C shape towards the bathroom side X1.

[0071] The outer shoji door joint frame gasket 752 is formed to extend in the vertical direction and contacts the surface of the inner shoji door joint frame 33 of the inner shoji door 3 on the changing room side X2 at the joint part 15 of the inner shoji door 3 and the outer shoji door 4. The upper end of the outer shoji door joint frame gasket 752 contacts the part of the upper frame side water stop part 713 (see Figure 6) on the outer shoji door upper side gasket 712 side, and the lower end contacts the part of the lower frame side water stop part 723 (see Figure 7) on the outer shoji door lower side gasket 722 side.

[0072] The above-mentioned inner shoji door joint frame gasket 751 and outer shoji door joint frame gasket 752 can stop water from entering between the joint frame 33 of the inner shoji door 3 and the joint frame 43 of the outer shoji door 4 at the joint portion 15 of the inner shoji door 3 and the outer shoji door 4 when the inner shoji door 3 and the outer shoji door 4 are in the closed position.

[0073] According to this embodiment, the following effects are achieved: The fitting 1 of this embodiment comprises a frame body 2 having a bottom frame 22, shoji screens (inner shoji screen 3, outer shoji screen 4) that are arranged movably in the left-right direction within the frame body 2 and open and close the opening of the frame body 2, and watertight gaskets (inner shoji screen lower gasket 721, outer shoji screen lower gasket 722) that are arranged on the bottom frame 22 and extend left-right only within the left-right range of the shoji screens (inner shoji screen 3, outer shoji screen 4) that are positioned in the closed position, and that come into contact with the lower ends of the shoji screens (inner shoji screen 3, outer shoji screen 4), At the lower end of the shoji screen (inner shoji screen 3, outer shoji screen 4), there is a lower end protrusion 322, 422 which protrudes downward from the underside of the lower frame body 321, 421 of the shoji screen (inner shoji screen 3, outer shoji screen 4) and comes into contact with a water-stop gasket (inner shoji lower gasket 721, outer shoji lower gasket 722), and the lower end protrusion 322, 422 protrudes downward from the underside of the lower frame body 321, 421 at a position inside both ends of the lower frame body 321, 421 in the forward direction.

[0074] As a result, the waterproof gaskets (inner shoji lower gasket 721, outer shoji lower gasket 722) come into contact with the lower end protrusions 322, 422 on the inside of the projection in the projection direction of the lower end of the inner shoji 3, so the waterproof gaskets (inner shoji lower gasket 721, outer shoji lower gasket 722) are positioned inside the projection direction of the lower end of the shoji (inner shoji 3, outer shoji 4), reducing the projection direction width of the lower frame 22. Therefore, the projection direction width of the fitting 1 can be reduced.

[0075] Furthermore, watertight performance can be ensured when the shoji screens (inner shoji screen 3, outer shoji screen 4) are in the closed position, and as the shoji screens (inner shoji screen 3, outer shoji screen 4) are opened, the area that comes into contact with the watertight gaskets (inner shoji screen lower gasket 721, outer shoji screen lower gasket 722) decreases, thereby reducing operating resistance. Therefore, watertightness is ensured by the watertight gaskets (inner shoji screen lower gasket 721, outer shoji screen lower gasket 722) that come into contact with the lower ends of the shoji screens (inner shoji screen 3, outer shoji screen 4), and the impact of contact resistance of the watertight gaskets (inner shoji screen lower gasket 721, outer shoji screen lower gasket 722) on the opening and closing operation of the shoji screens (inner shoji screen 3, outer shoji screen 4) can be suppressed, while the width of the fitting 1 in the expected direction can be reduced.

[0076] Furthermore, in this embodiment, the water stop gaskets (inner shoji lower gasket 721, outer shoji lower gasket 722) have upper surface inclined portions 721b, 722b that slope downward in the direction opposite to the side that contacts the shoji (inner shoji 3, outer shoji 4). Therefore, the upper surface inclined portions 721b, 722b allow water to flow along the slope, reducing water accumulation on the upper surface of the water stop gaskets (inner shoji lower gasket 721, outer shoji lower gasket 722) and improving water stop performance. Furthermore, because water flows away from the shoji (inner shoji 3, outer shoji 4), water stop performance can be further improved.

[0077] Furthermore, in this embodiment, by providing lower end protrusions 322, 422 on each of the inner shoji 3 and outer shoji 4, the inner shoji lower gasket 721 contacts the lower end protrusion 322 of the inner shoji 3 on the inside of the projection direction of the lower end of the inner shoji 3, and the outer shoji lower gasket 722 contacts the lower end protrusion 422 of the outer shoji 4 on the inside of the projection direction of the lower end of the outer shoji 4. As a result, the inner shoji lower gasket 721 is positioned inside the projection direction of the lower end of the inner shoji 3, and the outer shoji lower gasket 722 is positioned inside the projection direction of the lower end of the outer shoji 4, so the distance in the projection direction between the inner shoji 3 and outer shoji 4 can be reduced. Therefore, the gap between the inner shoji screen 3 and the outer shoji screen 4 in the prospective direction can be made small, and for example, when viewed from diagonally in front from the side where the gap between the inner shoji screen 3 and the outer shoji screen 4 can be seen at the joint 15 of the inner shoji screen 3 and the outer shoji screen 4, the gap between the inner shoji screen 3 and the outer shoji screen 4 is small, so the fitting 1 can be made to look neat.

[0078] In addition, in this embodiment, there is a packing arrangement groove 225 that is formed to extend in the left-right direction, which is the movement direction of the inner shoji screen 3 and the outer shoji screen 4, and is arranged in a straight line, and the packing arrangement groove 225 is arranged in a position in the prospective direction between the position where the lower end protrusion 322 of the inner shoji screen 3 is provided and the position where the lower end protrusion 422 of the outer shoji screen 4 is provided, and the inner shoji lower side packing 721 is attached to the packing arrangement groove 225 and formed to protrude toward the inner shoji screen 3, and the outer shoji lower side packing 722 is attached to the packing arrangement groove 225 and formed to protrude toward the outer shoji screen 4.

[0079] As a result, from the packing arrangement grooves 225 arranged in a straight line, the inner shoji lower packing 721 is arranged to protrude toward the inner shoji 3 on the side where the inner shoji 3 is arranged in the left-right direction, and the outer shoji lower packing 722 is arranged to protrude toward the outer shoji 4 on the side where the outer shoji 4 is arranged in the left-right direction. Therefore, since it is not necessary to provide multiple rows of packing arrangement grooves 225, the range of the prospective direction in which the packing arrangement grooves 225 are arranged can be minimized, thereby making it possible to reduce the prospective width of the lower frame 22. Therefore, the prospective width of the fitting 1 can be reduced.

[0080] In this embodiment, a water-stopping component 723 is provided between the inner and outer shoji lower packings 721 and 722, which extend in the left-right direction at different positions in the projection direction. This improves water-stopping performance.

[0081] While the preferred embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments and can be modified as appropriate.

[0082] For example, in the above embodiment, the fitting 1 is described as being applied to a sliding shoji door, but this is not limiting. For example, the fitting of the present disclosure may be applied to a single sliding door made up of one shoji door, a two-panel sliding door made up of two shoji doors, or a three-panel sliding door made up of three shoji doors.
