Description

[Technical Field]

[0001] The present disclosure relates to shoji screens and fittings. [Background technology]

[0002] Conventionally, there has been known a fitting comprising a frame body and a shoji screen slidably disposed within the frame body (see, for example, Patent Document 1). The shoji screen comprises a frame body having a stile and a glass panel disposed within the frame body, and the edge of the glass panel is adhered and fixed to the frame with an adhesive. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2017-57676 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, an adhesive is placed in the glass placement groove of the frame, and then the edge of the glass panel is inserted into the glass placement groove of the frame, thereby adhering and fixing the glass panel to the frame with the adhesive. In this case, there is a possibility that the adhesive may protrude outside the frame. Furthermore, when the adhesive placed inside the glass placement groove of the frame is viewed from the outside through the glass panel, the edge of the adhesive may protrude in a wavy manner rather than uniformly. If the wavy edge of the adhesive is visible, it may impair the design. Therefore, it is desirable to improve the design of a configuration in which the edge of a glass panel (face material) is adhered to a frame with an adhesive.

[0005] The present disclosure aims to provide shoji screens and fittings that can improve design in a configuration in which the ends of the face material are adhered to the frame with an adhesive. [Means for solving the problem]

[0006] The present disclosure relates to a shoji screen comprising a frame body having a stile and a panel placed within the frame body, the frame having an opening into which an end of the panel material is inserted, a panel material placement groove into which the end of the panel material is placed and adhered with an adhesive, an adhesive storage pocket formed in communication with the panel material placement groove and into which the adhesive placed in the panel material placement groove flows when the end of the panel material is inserted into the panel material placement groove, a front wall portion formed on the front side of the panel material placement groove and extending towards the panel material side, and an extension portion extending from the panel material side end of the front wall portion along the surface of the panel material from the front side of the panel material placement groove towards the back side.

[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 installed 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 face material will be described. The face material is not limited to a glass panel. In addition to glass panels, other face materials include, for example, resin panels and aluminum-resin composite panels. In this embodiment, a case where a single glass panel is used as the face material will be described. Note that double or triple glass may also be used as the glass panel as the face material. Furthermore, laminated glass may also be used as the glass panel as the face material.

[0009] As shown in Figures 1 to 3, the fitting 1 of one embodiment is installed in an opening formed in a modular bathroom (not shown) serving 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 as to be able to open and close, 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 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 both formed in a frame shape that opens downward. The upper end of the upper frame stile 31 of the inner shoji screen 3 is inserted into the upper frame bathroom-side inlet 211. The upper end of the upper frame stile 41 of the outer shoji screen 4 is inserted into the upper frame changing room-side inlet 212.

[0013] An inner shoji side door roller holder 211a is provided at the upper end of the upper frame bathroom side intake 211. A hoist 37 connected to the upper frame stile 31 of the inner shoji side door roller holder 211a is arranged so that it can move left and right. An outer shoji side door roller holder 212a is provided at the top of the upper frame changing room side intake 212. A hoist 47 connected to the upper frame stile 41 of the outer shoji side door roller holder 212a is arranged so that it can move left and right.

[0014] 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.

[0015] 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.

[0016] The inner shoji screen 3 and the outer shoji screen 4 can slide within the frame body 2. Both the inner shoji screen 3 and the outer shoji screen 4 are 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.

[0017] 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.

[0018] Each 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.

[0019] Next, we will explain the structure in which the glass panels 36, 46 of the inner shoji 3 and outer shoji 4 are adhered and fixed to the frames 35, 45 with adhesive 10. In this embodiment, the joining frames 33, 43 of the inner shoji 3 and outer shoji 4 are both located at the joining part of the inner shoji 3 and outer shoji 4 in the center of the left-right direction of the building material 1. The inner shoji 3 and outer shoji 4 have a shape that is inverted left to right, and the position and shape of the joining frames 33, 43 and door edge frames 34, 44 are symmetrical. In this embodiment, the inner shoji 3 and outer shoji 4 have the same shape except for the fact that they are inverted left to right, so we will explain the outer shoji 4.

[0020] As shown in Figures 4 and 5, in the outer shoji screen 4, the upper frame 41, lower frame 42, joint frame 43 and end frame 44 have glass placement grooves 413, 423, 433, 443 (surface material placement grooves) in which the ends of the glass panel 46 are placed.

[0021] The structure for fixing the ends of the glass panels 46 in the upper and lower frames 41 and 42 to the glass arrangement grooves 413 and 423 with adhesive 10 is the same as the structure for fixing the ends of the glass panels 46 in the joint frame 43 and the end frame 44 to the glass arrangement grooves 433 and 443 with adhesive 10, but with the left-right orientation changed to up-down. The structure for the adhesive fixing structure of the upper frame 41 turned horizontally is the same as the adhesive fixing structure of the joint frame 43, and the structure for the adhesive fixing structure of the lower frame 42 turned horizontally is the same as the adhesive fixing structure of the end frame 44. Therefore, in the following explanation, only the joint frame 43 and the end frame 44 will be explained. The upper frame 41 and the lower frame 42 will be given the same reference numerals as the joint frame 43 and the end frame 44, and their explanation will be omitted.

[0022] 4, the upper frame 41 includes an end fixing frame 411 to which the upper end of the glass panel 46 is fixed. The end fixing frame 411 includes a glass placement groove 413 (face material placement groove) having an opening 412 into which the upper end of the glass panel 46 is inserted, a pair of adhesive storage pockets 414, a pair of front side wall portions 415, a pair of extension portions 416, and a pair of restriction wall portions 417.

[0023] 4, the lower frame 42 includes an end fixing frame 421 to which the lower end of the glass panel 46 is fixed. The end fixing frame 421 includes a glass placement groove 423 (face material placement groove) having an opening 422 into which the lower end of the glass panel 46 is inserted, a pair of adhesive storage pockets 424, a pair of front side wall portions 425, and a pair of restriction wall portions 427.

[0024] In the configuration relating to both left and right ends of the glass panel 46, the joint frame 43 has an end fixing frame 431 to which the end of the glass panel 46 on the joint frame 43 side in the left and right direction is fixed, as shown in Fig. 5. The end fixing frame 431 has a glass arrangement groove 433 (face material arrangement groove) having an opening 432 into which the end of the glass panel 46 on the joint frame 43 side in the left and right direction is inserted, a pair of adhesive storage pockets 434, a pair of front side wall portions 435, a pair of extension portions 436, and a pair of restriction wall portions 437.

[0025] 5, the door stile 44 has an end fixing frame 441 to which the end of the glass panel 46 on the door stile 44 side in the left-right direction is fixed. The end fixing frame 441 has a glass placement groove 443 (surface material placement groove) having an opening 442 into which the end of the glass panel 46 on the door stile 44 side in the left-right direction is inserted, a pair of adhesive storage pockets 444, a pair of front side wall portions 445, and a pair of restriction wall portions 447.

[0026] The following describes a configuration in which glass panel 46 in joint frame 43 is adhered with adhesive 10. As shown in Fig. 5, end fixing frame 431 of joint frame 43 includes glass placement groove 433 (surface material placement groove) having opening 432, a pair of adhesive storage pockets 434, a pair of front side wall portions 435, a pair of extension portions 436, and a pair of restriction wall portions 437.

[0027] As shown in Fig. 6, the glass positioning groove 433 is formed to extend over the entire longitudinal area of ​​the joint frame 43. As shown in Fig. 5, the end of the glass panel 46 is inserted into the opening 432 of the glass positioning groove 433. The opening 432 is formed so that the inner periphery side of the joint frame 43 is open. The end of the glass panel 46 is formed with an end face 461 that faces outward in the plane direction of the glass panel 46 and extends in the thickness direction of the glass panel 46, and a pair of inclined end faces 462 with chamfered corners.

[0028] An edge of the glass panel 46 is placed in the glass placement groove 433 and adhered with adhesive 10. The glass placement groove 433 has a glass-facing surface 433a to which an end face 461 of the end of the glass panel 46 is adhered in a facing state. The glass-facing surface 433a and the end face 461 of the glass panel 46 are adhered and fixed with adhesive 10.

[0029] A pair of adhesive storage pockets 434 are provided on both sides of the glass placement groove 433. Each of the pair of adhesive storage pockets 434 is formed to communicate with the glass placement groove 433. When the end of the glass panel 46 is inserted into the glass placement groove 433, the adhesive 10 arranged on the back side of the glass placement groove 433 is pushed out and flows into the adhesive storage pocket 434. As a result, the adhesive storage pocket 434 stores excess adhesive 10 that overflows from between the end face 461 of the end of the glass panel 46 and the glass-facing surface 433a of the glass placement groove 433.

[0030] As shown in Fig. 5, the pair of front side walls 435 are formed on the front side of the glass placement groove 433, extending toward the bathroom-side X1 side or the changing room-side X2 side of the glass panel 46. The front side walls 435 extend in a direction intersecting the surface direction of the glass panel 46, approaching the bathroom-side X1 side or the changing room-side X2 side of the glass panel 46, and are positioned with a gap S31 formed between them and the glass panel 46. The surfaces of the pair of front side walls 435 facing the glass panel 46 form the outline of the opening 432 of the glass placement groove 433. The gap S31 is provided in consideration of manufacturing variations (tolerances) in the thickness of the glass panel 46 so that the glass panel 46 can be inserted into the opening 432.

[0031] The pair of extension portions 436 each extend a predetermined length from the end of the front wall portion 435 on the glass panel 46 side along the surface of the glass panel 46 from the front side toward the back side of the glass placement groove 433 so as to close the front side of the pocket opening 434a of the adhesive storage pocket 434. The extension portions 436 are formed to a length such that the front side portion of the adhesive 10 stored in the adhesive storage pocket 434 is not visible.

[0032] 5, the pair of restricting wall portions 437 are each formed on the rear side of the glass placement groove 433. The pair of restricting wall portions 437 are formed on glass-facing surfaces 433a (facing surfaces) that face the end faces 461 of the glass panel 46 on the rear side of the glass placement groove 433. When the glass panel 46 is inserted into the glass placement groove 433, the pair of restricting wall portions 437 restrict movement of the adhesive 10 in the thickness direction of the glass panel 46 so that the adhesive 10 is contained within a range of a predetermined width.

[0033] When the glass panel 46 is placed in the glass placement groove 433, the pair of regulating wall portions 437 are formed in the shape of walls rising from the back side to the front side of the glass placement groove 433 on one side and the other side in the direction along the thickness of the glass panel 46 on the glass-facing surface 433a at the back side of the glass placement groove 433 in the end fixing frame 431 of the outer shoji screen 4. By providing the pair of regulating wall portions 437 so as to regulate the position where the adhesive 10 is placed, the amount of adhesive 10 used can be kept to a necessary minimum.

[0034] A gap S32 is formed between the pair of regulating wall portions 437 and the bathroom side X1 or the dressing room side X2 surface of the glass panel 46, allowing the adhesive 10 to flow out toward the adhesive storage pocket 434.

[0035] As shown in FIG. 6 , a pair of sealants 438 are provided on both longitudinal end sides of the glass placement groove 433. The pair of sealants 438 are formed in a block shape. In this embodiment, the pair of sealants 438 are arranged at both longitudinal end sides of the glass placement groove 433, at positions that are inward from the longitudinal end sides of the glass placement groove 433 toward the center, in order to avoid screw holes (not shown) formed at both longitudinal end sides. The pair of sealants 438 are arranged on the far side of the glass placement groove 433. The pair of sealants 438 prevent the adhesive 10 from leaking out from the longitudinal end sides of the joint frame 43. This allows the adhesive 10 to be securely held in the glass placement groove 433.

[0036] The sealing material 438 is made of a cushioning material having cushioning properties, and is crushed and deformed by the edge of the glass panel 46 when the edge of the glass panel 46 is placed in the glass placement groove 433 during manufacturing. Therefore, productivity can be improved when the edge of the glass panel 46 is placed in the glass placement groove 433 during manufacturing.

[0037] Next, the structure in which the glass panel 46 in the door end frame 44 is adhered with the adhesive 10 will be described. As shown in Fig. 5, the end fixing frame 441 of the door end frame 44 has a glass arrangement groove 443 (surface material arrangement groove) with an opening 442, a pair of adhesive storage pockets 444, a pair of front side wall portions 445, and a pair of restricting wall portions 447. The door end frame 44 does not have the pair of extension portions 436 of the door joint frame 43.

[0038] As shown in Fig. 7, the glass positioning groove 443 is formed to extend over the entire longitudinal area of ​​the door stile 44. As shown in Fig. 5, the end of the glass panel 46 is inserted into the opening 442 of the glass positioning groove 443. The opening 442 is formed so that the inner periphery side of the door stile 44 is open. The end of the glass panel 46 is formed with an end face 461 that faces outward in the plane direction of the glass panel 46 and extends in the thickness direction of the glass panel 46, and a pair of inclined end faces 462 with chamfered corners.

[0039] An edge of the glass panel 46 is placed in the glass placement groove 443 and adhered with adhesive 10. The glass placement groove 443 has a glass-facing surface 443a to which an end face 461 of the end of the glass panel 46 is adhered in a facing state. The glass-facing surface 443a and the end face 461 of the glass panel 46 are adhered and fixed with adhesive 10.

[0040] A pair of adhesive storage pockets 444 are provided on both sides of the glass placement groove 443. Each of the pair of adhesive storage pockets 444 is formed to communicate with the glass placement groove 443. When the end of the glass panel 46 is inserted into the glass placement groove 443, the adhesive 10 arranged on the back side of the glass placement groove 443 is pushed out and flows into the adhesive storage pocket 444. As a result, the adhesive storage pocket 444 stores excess adhesive 10 that overflows from between the end face 461 of the end of the glass panel 46 and the glass-facing surface 443a of the glass placement groove 443.

[0041] In this embodiment, since the initial positioning of the end of the glass panel 46 is performed in the door frame 44, it is expected that the amount of adhesive 10 that protrudes will be small.Therefore, the width of the adhesive storage pocket 444 in the door frame 44 from the front to the back is formed to be smaller than that of the adhesive storage pocket 434 in the joint frame 43, and the length in the thickness direction of the glass panel 46 is formed to be smaller than that of the adhesive storage pocket 434 in the joint frame 43.

[0042] Therefore, with regard to the amount of adhesive 10 used to bond the ends of the glass panels 46, the amount of adhesive 10 used on the end stile 44 of the door end frame 44 and the joint frame 43 is made less than the amount of adhesive 10 used on the joint frame 43. However, without being limited to this, with regard to the amount of adhesive 10 used to bond the ends of the glass panels 46, the amount of adhesive 10 used on the joint frame 43 of the door end frame 44 and the joint frame 43 may be made less than the amount of adhesive 10 used on the joint frame 43.

[0043] As shown in Fig. 5, the pair of front side walls 445 are formed on the front side of the glass placement groove 443, extending toward the bathroom-side X1 side or the changing room-side X2 side of the glass panel 46. The front side walls 445 extend in a direction intersecting the surface direction of the glass panel 46, approaching the bathroom-side X1 side or the changing room-side X2 side of the glass panel 46, and are positioned with a gap S41 formed between them and the glass panel 46. The surfaces of the pair of front side walls 445 facing the glass panel 46 form the outline of the opening 442 of the glass placement groove 443. The gap S41 is provided in consideration of manufacturing variations (tolerances) in the thickness of the glass panel 46 so that the glass panel 46 can be inserted into the opening 442.

[0044] The pair of front side walls 445 are formed with inner surfaces 445a that extend along the bathroom-side X1 and undressing-room-side X2 surfaces of the glass panel 46. The inner surfaces 445a are formed to a length that prevents the front portion of the adhesive 10 stored in the adhesive storage pocket 444 from being visible.

[0045] 5, the pair of restricting wall portions 447 are each formed on the rear side of the glass placement groove 443. The pair of restricting wall portions 447 are formed on glass-facing surfaces 443a (facing surfaces) that face the end faces 461 of the glass panel 46 on the rear side of the glass placement groove 443. When the glass panel 46 is inserted into the glass placement groove 443, the pair of restricting wall portions 447 restrict movement of the adhesive 10 in the thickness direction of the glass panel 46 so that the adhesive 10 is contained within a range of a predetermined width.

[0046] When the glass panel 46 is placed in the glass placement groove 443, the pair of regulating wall portions 447 are formed in the shape of walls rising from the back side to the front side of the glass placement groove 443 on one side and the other side in the direction along the thickness of the glass panel 46 on the glass-facing surface 443a at the back side of the glass placement groove 443 in the end fixing frame 441 of the outer shoji screen 4. By providing the pair of regulating wall portions 447 so as to regulate the position where the adhesive 10 is placed, the amount of adhesive 10 used can be kept to a necessary minimum.

[0047] The pair of regulating walls 447 have corners 447a, which are formed so as to come into contact with the inclined end faces 462 at the ends of the glass panel 46. By providing the regulating walls 447, when the glass panel 46 is inserted into the glass placement groove 443 during the manufacture of the outer shoji screen 4, the corners 447a come into contact with the inclined end faces 462 at the ends of the glass panel 46, thereby enabling the end faces 461 of the end of the glass panel 46 to be positioned in the insertion direction.

[0048] As shown in FIG. 7 , a pair of sealants 448 are provided on both longitudinal end sides of the glass placement groove 443. The pair of sealants 448 are formed in a block shape. In this embodiment, the pair of sealants 448 are arranged at both longitudinal end sides of the glass placement groove 443, at positions that are inward from the longitudinal end sides of the glass placement groove 443 toward the center, in order to avoid screw holes (not shown) formed at both longitudinal end sides. The pair of sealants 448 are arranged on the back side of the glass placement groove 443. The pair of sealants 448 prevent the adhesive 10 from leaking out from the longitudinal end sides of the door stile 44. This allows the adhesive 10 to be securely held in the glass placement groove 443.

[0049] The sealing material 448 is made of a cushioning material having cushioning properties, and is crushed and deformed by the edge of the glass panel 46 during manufacturing when the edge of the glass panel 46 is placed in the glass placement groove 443. Therefore, productivity can be improved during manufacturing when the edge of the glass panel 46 is placed in the glass placement groove 443.

[0050] Next, we will explain how to adhere a glass panel 46 to the door frame 43 and door end frame 44 of the outer shoji screen 4 using adhesive 10.

[0051] First, as shown in Figure 8A, in the door stile 44, with the adhesive 10 placed on the glass-facing surface 443a of the glass arrangement groove 443, the left-right end of the glass panel 46 on the door stile 44 side is inserted into the glass arrangement groove 443 of the door stile 44. A sealant 448 (see Figure 7) is placed at both longitudinal ends of the glass arrangement groove 443 of the door stile 44. This makes it possible to prevent the adhesive 10 from leaking out from the longitudinal ends of the door stile 44 when the glass panel 46 is placed in the glass arrangement groove 443.

[0052] When the glass panel 46 is inserted into the glass arrangement groove 443, as shown in Fig. 8B, a pair of inclined end faces 462 at the end of the glass panel 46 on the door stile 44 side come into contact with the corners 447a of the pair of regulating walls 447. This positions the end of the glass panel 46, and the end of the glass panel 46 is adhered and fixed with the adhesive 10.

[0053] Here, the adhesive 10 that overflows from the glass arrangement groove 443 is stored in the adhesive storage pocket 444. Therefore, the adhesive 10 is prevented from spilling out to the outside of the door frame 44.

[0054] In addition, the length of the inner surface 445a of the front side wall portion 445 along the surface of the glass panel 46 is formed to be a length such that the front portion of the adhesive 10 stored in the adhesive storage pocket 444 is not visible.

[0055] 8B , when the adhesive storage pocket 444 on the changing room side X2 is viewed through the glass panel 46 from the bathroom side X1, when the angle from the direction perpendicular to the bathroom side X1 surface of the glass panel 46 to the glass panel 46 side (the angle from the inner surface of the front wall portion 445 to the glass panel 46 side) is in the angle range A1 from 0° to α1, the adhesive storage pocket 444 is shielded by the inner surface 445a of the front wall portion 445, and the adhesive 10 is not visible through the glass panel 46. Furthermore, when the angle from the direction perpendicular to the bathroom side X1 surface of the glass panel 46 to the glass panel 46 side is in the angle range A2 from α1 to 90°, the adhesive 10 is visible through the glass panel 46.

[0056] When the glass panel 46 is viewed at an angle α1 from the bathroom side X1, the refractive index of the glass of the glass panel 46 causes the incident angle α2 of light from inside the adhesive storage pocket 444 to be refracted to a refraction angle α1, resulting in the light being viewed at the angle α1. Therefore, taking into consideration the refractive index and thickness of the glass panel 46, the length L1 of the inner surface 445a of the front wall 445 along the surface of the glass panel 46 is set to determine the angle α1 at which the glass panel 46 is viewed from the front and the range at which the interior of the adhesive storage pocket 444 is visible. In this embodiment, for example, when the thickness of the glass panel 46 is 5 mm, the length L1 of the inner surface 445a of the front wall 445 along the surface of the glass panel 46 is set to 2.5 mm so that the angle α1 with respect to the glass panel 46 when viewed from the front is 38°.

[0057] Here, in the longitudinal direction of the glass placement groove 443, the adhesive 10 overflows in a large amount in areas where there is a large amount of adhesive 10, and the adhesive 10 overflows in a small amount in areas where there is little adhesive 10. Therefore, in the longitudinal direction of the glass placement groove 443, the ends of the overflowing portions of the adhesive 10 are wavy and not uniform, which makes the appearance unattractive.

[0058] In contrast, in this embodiment, an inner surface 445a is provided on the front wall portion 445 on the changing room side X2. As a result, when the glass panel 46 is viewed from the bathroom side X1, adhesive portion 10a at the end of the adhesive 10, where the adhesive 10 protrudes unevenly and wavy in the longitudinal direction, is hidden by the inner surface 445a of the front wall portion 445 on the changing room side X2 and is not visible. Instead, adhesive portion 10b, where the adhesive 10 is uniformly present along the linear inner surface 445a extending in the longitudinal direction of the front wall portion 445 and is located inside adhesive portion 10a at the end of the protruding portion of the adhesive 10, is visible. Therefore, the adhesive 10 can have a good appearance even when viewed through the glass panel 46.

[0059] Next, as shown in Fig. 9A, with adhesive 10 placed on glass-facing surface 443a of glass placement groove 443, the left-right end of glass panel 46 on the side of joint frame 43 is inserted into glass placement groove 433 of joint frame 43. Sealant 438 (see Fig. 6) is placed at both longitudinal ends of glass placement groove 433 of joint frame 43. This makes it possible to prevent adhesive 10 from leaking out from the longitudinal ends of joint frame 43 when glass panel 46 is placed in glass placement groove 433.

[0060] Here, the door end frame 44 and the door joint frame 43 are assembled with the upper frame 41 and the lower frame 42. Since the external dimensions of the outer shoji 4 are determined by design, the distance between the door joint frame 43 and the door end frame 44 is also determined by design.

[0061] As an example of the dimensional tolerance of the door end stile 44 and the joint stile 43, in this embodiment, the dimensional tolerance of the door end stile 44 and the joint stile 43 is, for example, ±0.5 mm due to the processing accuracy of the stiles. In contrast, the dimensional tolerance of the left-right length of the glass panel 46 is, for example, ±2 mm due to the processing accuracy of the glass panel 46. Compared to the dimensional tolerance of the door end stile 44 and the joint stile 43, the dimensional tolerance of the left-right length of the glass panel 46 is larger.

[0062] Therefore, when the end of the glass panel 46 on the door frame 44 side is positioned on the door frame 44 side, and then the end of the glass panel 46 on the door frame 43 side is placed on the door frame 43, the position of the end of the glass panel 46 on the door frame 43 side will vary due to variations in the dimensional tolerances of the glass panel 46.

[0063] Therefore, variations in the dimensional tolerance of the glass panel 46 cause differences in the thickness of the adhesive 10 placed between the end face 461 of the end of the glass panel 46 and the glass-facing surface 433a of the glass placement groove 433. Therefore, variations in the dimensional tolerance of the glass panel 46 cause differences in the amount of adhesive 10 required to be placed between the end face 461 of the end of the glass panel 46 and the glass-facing surface 433a of the glass placement groove 433.

[0064] In response to this, in the present disclosure, an adhesive storage pocket 434 is provided that communicates with the glass placement groove 433. This allows the adhesive 10 that overflows when the glass panel 46 is placed to be stored in the adhesive storage pocket 434 in response to variations in the length of the glass panel 46 in the left-right direction, thereby preventing the adhesive 10 from spilling out of the joint frame 43.

[0065] Also, a pair of extensions 436 are provided to close the front side of the pocket opening 434a of the adhesive storage pocket 434. The extensions 436 are formed to a length that makes the front side of the adhesive 10 stored in the adhesive storage pocket 434 invisible.

[0066] 9B , when the adhesive storage pocket 434 on the dressing room side X2 is viewed through the glass panel 46 from the bathroom side X1, when the angle from the direction perpendicular to the bathroom side X1 surface of the glass panel 46 toward the glass panel 46 side (the angle from the inner surface of the front wall portion 435 toward the glass panel 46 side) is in an angle range B1 from 0° to angle β1, the adhesive storage pocket 434 is shielded by the extension portion 436, and the adhesive 10 is not visible through the glass panel 46. Furthermore, when the angle from the direction perpendicular to the bathroom side X1 surface of the glass panel 46 toward the glass panel 46 side is in an angle range B2 from angle β1 to 90°, the adhesive 10 is visible through the glass panel 46.

[0067] When the glass panel 46 is viewed at an angle β1 from the bathroom side X1, the refractive index of the glass of the glass panel 46 causes the incident angle β2 of light from inside the adhesive storage pocket 434 to be refracted at a refraction angle β1, resulting in the light being viewed at the angle β1. Therefore, taking into consideration the refractive index of the glass panel 46 and the thickness of the glass panel 46, the length L2 of the extension portion 436 along the surface of the glass panel 46 is set to determine the angle β1 at which the glass panel 46 is viewed from the front and the range at which the interior of the adhesive storage pocket 434 is visible. In this embodiment, for example, when the thickness of the glass panel 46 is 5 mm, the length L2 of the extension portion 436 along the surface of the glass panel 46 is set to 3.0 mm so that the angle β1 with respect to the glass panel 46 when viewed from the front is 45°.

[0068] Here, in the longitudinal direction of the glass placement groove 433, the adhesive 10 overflows in a large amount in areas where there is a large amount of adhesive 10, and the adhesive 10 overflows in a small amount in areas where there is little adhesive 10. Therefore, in the longitudinal direction of the glass placement groove 433, the ends of the overflowing portions of the adhesive 10 are wavy and not uniform, which makes the appearance unattractive.

[0069] In contrast, in this embodiment, a pair of extensions 436 are provided to close the front side of the pocket opening 434a of the adhesive storage pocket 434. As a result, when the glass panel 46 is viewed from the bathroom side X1, adhesive portion 10a at the end of the adhesive 10, where the adhesive 10 protrudes unevenly and wavy in the longitudinal direction, is hidden and not visible by extensions 436 extending from the front wall portion 435 on the undressing room side X2 to the rear side. Instead, adhesive portion 10b, where adhesive 10 is uniformly present on the inside of adhesive portion 10a at the end of the protruding portion of adhesive 10 along the linear extensions 436 extending in the longitudinal direction of the front wall portion 435, is visible. Therefore, the adhesive 10 can look good even when viewed through the glass panel 46.

[0070] Here, the above explanation explains the door end frame 44 and the door joint frame 43, and the explanation of the door end frame 44 and the door joint frame 43 can be used for the upper frame 41 and the lower frame 42, but supplementary explanation will be provided about the upper frame 41 and the lower frame 42.

[0071] In this embodiment, with regard to the amount of adhesive 10 used to bond the ends of the glass panels 46 in the end stile 44 and the joint stile 43, the amount of adhesive 10 used in the end stile 44 is less than the amount of adhesive 10 used in the joint stile 43. On the other hand, with regard to the amount of adhesive 10 used to bond the ends of the glass panels 46 in the upper stile 41 and the lower stile 42, the amount of adhesive 10 used in the lower stile 42 is less than the amount of adhesive 10 used in the upper stile 41. However, without being limited to this, the amount of adhesive 10 used to bond the ends of the glass panel 46 in the upper frame 41 and the lower frame 42 may be less than the amount of adhesive 10 in the upper frame 41 of the upper frame 41 and the lower frame 42.

[0072] In this embodiment, in the door end frame 44 and the door joint frame 43, the pair of sealants 438, 448 are arranged at both longitudinal end sides of the glass arrangement grooves 433, 443, in positions that are inward from the longitudinal end of the glass arrangement grooves 433, 443 toward the center, in order to avoid the screw holes formed at both longitudinal end sides of the glass arrangement grooves 433, 443. On the other hand, in the upper frame 41 and the lower frame 42, although not shown, no screw holes are formed at both longitudinal end sides of the glass arrangement grooves 413, 413, so the pair of sealants are arranged at both longitudinal end sides of the glass arrangement grooves 413, 413. In addition, in the upper frame 41 and the lower frame 42, as with the door end frame 44 and the door joint frame 43, a pair of sealing materials may be placed at both longitudinal end sides of the glass placement groove 413, 413, at a position toward the center from the longitudinal end of the glass placement groove 413, 413.

[0073] According to this embodiment, the following effects are achieved: The outer screen 4 of this embodiment includes a frame 45 having a joint frame 43, and a glass panel 46 arranged within the frame 45. The joint frame 43 has an opening 432 into which the end of the glass panel 46 is inserted, a glass placement groove 433 into which the end of the glass panel 46 is bonded with adhesive 10, an adhesive storage pocket 434 formed in communication with the glass placement groove 433 and into which the adhesive 10 arranged in the glass placement groove 433 flows when the end of the glass panel 46 is inserted into the glass placement groove 433, a front side wall portion 435 formed on the front side of the glass placement groove 433 and extending toward the glass panel 46 side, and an extension portion 436 extending from the glass panel 46-side end of the front side wall portion 435 along the surface of the glass panel 46 from the front side of the glass placement groove 433 toward the back side.

[0074] As a result, by providing an adhesive storage pocket 434 that communicates with the glass arrangement groove 433, it is possible to accommodate variations in the length of the glass panel 46 in the left-right direction, and by storing the adhesive 10 that overflows when the glass panel 46 is arranged in the adhesive storage pocket 434, it is possible to prevent the adhesive 10 from spilling out to the outside of the joint frame 43. This improves the design.

[0075] 9B , when the adhesive storage pocket 434 on the dressing room side X2 is viewed from the bathroom side X1 through the glass panel 46, the adhesive 10 overflowing from the glass placement groove 433 is shielded by the extension 436 and is not visible through the glass panel 46 when the angle from the direction perpendicular to the bathroom side X1 surface of the glass panel 46 to the glass panel 46 side (the angle from the inner surface of the front wall portion 435 to the glass panel 46 side) is in an angle range B1 from 0° to β1, because the adhesive storage pocket 434 is shielded by the extension 436. Furthermore, the adhesive 10 is visible through the glass panel 46 when the angle from the direction perpendicular to the bathroom side X1 surface of the glass panel 46 to the glass panel 46 side is in an angle range B2 from β1 to 90°. Adhesive portion 10a at the end of the adhesive 10, where the adhesive 10 protrudes unevenly and wavy in the longitudinal direction, is hidden by extension 436 extending from the front side wall 435 on the changing room side X2 to the rear side and is not visible, but adhesive portion 10b, where adhesive 10 is uniformly present on the inside of adhesive portion 10a at the end of the protruding portion of adhesive 10 along linear extension 436 extending in the longitudinal direction of front side wall 435, is visible. Therefore, adhesive 10 can look good even when viewed through glass panel 46, thereby improving design.

[0076] Furthermore, in this embodiment, the joint frame 43 has a restricting wall portion 437 formed on a glass-facing surface 433a that faces the end face 461 of the glass panel 46 at the back side of the glass placement groove 433, and that restricts movement of the adhesive 10 so that the adhesive 10 fits within a predetermined width range in the thickness direction of the glass panel 46 when the glass panel 46 is inserted into the glass placement groove 433. Thus, by providing a pair of restricting wall portions 437 that restrict the position where the adhesive 10 is placed, the amount of adhesive 10 used can be kept to a necessary minimum, thereby reducing the cost required for the adhesive 10.

[0077] In this embodiment, the joint frame 43 has a sealant 438 that is disposed on the longitudinal end side of the glass placement groove 433 and prevents the adhesive 10 from flowing out from the longitudinal end of the joint frame 43. This prevents the adhesive 10 from flowing out from the longitudinal end of the glass placement groove 433, thereby enabling the adhesive 10 to be securely held in the glass placement groove 433.

[0078] 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.

[0079] Regarding the shape of the glass-facing surface 443a formed on the rear side of the glass placement groove 443 of the door stile 44 shown in FIG. 5 of the above-mentioned embodiment, for example, as in the first modified embodiment shown in FIG. 10, a rib 439 may be provided that protrudes toward the glass panel 46 from the glass-facing surface 443a formed on the rear side of the glass placement groove 443 of the door stile 44A. In this case, the pair of regulating wall portions 447A are positioned on the outer side in the thickness direction of the glass panel 46 so as not to contact the inclined end surface 462 of the glass panel 46. As a result, when the end of the glass panel 46 is placed in the glass placement groove 443, the rib 439 abuts against the end surface 461 of the end of the glass panel 46, thereby positioning the end of the glass panel 46. Note that a similar configuration can also be adopted for the bottom stile 42.

[0080] Furthermore, with regard to the shape of the glass-facing surface 443a formed on the rear side of the glass placement groove 443 of the door stile 44 shown in FIG. 5 of the embodiment, as in a second modified embodiment shown in FIG. 11, the positions of the pair of regulating wall portions 447B may be positioned so that the width of the glass-facing surface 443a is narrowed, and the surfaces of the regulating wall portions 447B facing the glass panel 46 may be brought into contact with the end face 461 of the end of the glass panel 46. In this case, when the end of the glass panel 46 is placed in the glass placement groove 443, the surfaces of the regulating wall portions 447B facing the glass panel 46 abut against the end face 461 of the end of the glass panel 46, thereby positioning the end of the glass panel 46. Note that a similar configuration can also be adopted for the bottom stile 42.

[0081] In addition, in the above embodiment, the extensions provided on the joint frame 43 and the upper frame 41 may also be provided on the door end frame 44 and the lower frame 42. Furthermore, the extensions may be provided on only one of the upper frame 41, the lower frame 42, the joint frame 43, and the door end frame 44, or may be provided on one or more of the frames.

[0082] In addition, in the above embodiment, the fitting 1 is described as being applied to a sliding shoji door, but is not limited to this. 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, a three-panel sliding door made up of three shoji doors, a fixed shoji door that cannot be opened or closed, a folding door, or a swing door.
