DETAILED DESCRIPTION OF THE INVENTION

[0009] BEST MODE FOR CARRYING OUT THE INVENTION A fitting according to a preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0010] As shown in Figures 1 to 3, the fitting 10 according to this embodiment comprises an opening frame 12 fixed to an opening in a building skeleton, and an outer shoji screen 14 and an inner shoji screen 15 slidably disposed inside the opening frame 12. In this embodiment, the fitting 10 is a sliding window in which an opening 16 formed inside the opening frame 12 can be opened and closed by sliding the shoji screens 14, 15 left and right. The shoji screens 14, 15 may be single-sliding windows in which one side is fixed to the opening frame 12 and the other slides. The number of shoji screens installed may be three or more.

[0011] The opening frame 12 has a rectangular opening 16 formed by framing the four sides of the opening frame 12 with an upper frame 12a, a lower frame 12b, and left and right vertical frames 12c and 12d.

[0012] In this application, the "visible direction" refers to the indoor-outdoor direction of the fitting 10, i.e., the direction from the indoor side toward the outdoor side or the opposite direction (the direction indicated by arrow Z in the figure), and the "visible surface" refers to a surface extending along the visible direction. The "visible direction" refers to a direction perpendicular to the visible direction, and in the case of a vertical frame 12c or the like that is long in the vertical direction, it refers to the left-right direction perpendicular to the longitudinal direction (the direction indicated by arrow X in the figure), and in the case of an upper frame 12a or the like that is long in the horizontal direction, it refers to the up-down direction perpendicular to the longitudinal direction (the direction indicated by arrow Y in the figure). The "visible surface" refers to a surface along the visible direction. The "inside of the frame" refers to the inner part of a frame-shaped member such as an opening frame 12. The "outside of the frame" refers to the outer part of a frame-shaped member such as an opening frame 12. The "inside frame direction" refers to the direction from the outside of the frame-shaped member toward the inside of the frame. The "outside frame direction" refers to the direction from the inside of the frame-shaped member toward the outside of the frame.

[0013] First, the overall configuration of the fitting 10 will be described.

[0014] The opening frame 12 is a composite window frame that combines a metal frame material 18 disposed on the exterior side with a resin frame material 20 disposed on the interior side. The metal frame material 18 is an extruded shape made of a metal material such as aluminum. The resin frame material 20 is an extruded shape made of a resin material such as polyvinyl chloride (PVC). The metal frame material 18 includes a metal upper frame 18a, a metal lower frame 18b, and left and right vertical metal frames 18c, 18d. The resin frame material 20 includes a resin upper frame 20a, a resin lower frame 20b, and left and right vertical resin frames 20c, 20d.

[0015] As shown in FIG. 2, the upper frame 12a is configured by connecting a resin upper frame 20a to a metal upper frame 18a fixed to the building frame with screws 22.

[0016] The metal upper frame 18a is configured to improve thermal insulation performance by connecting the outdoor member 18a1 and the indoor member 18a2 with the insulating material 18a3. The outdoor member 18a1 forms the drainage surface of the opening frame 12. A rail piece 24a is formed protruding from the frame-inside visible surface of the outdoor member 18a1. A rail piece 25a is formed protruding from the frame-inside visible surface of the indoor member 18a2. The metal upper frame 18a may be configured as a single member without using the insulating material 18a3.

[0017] The resin upper frame 20a comprises a base member 20a1 and an angle member 20a2. The base member 20a1 has rail pieces 24b and 25b aligned in the projection direction on its inner projection surface, giving it a generally crank-shaped overall shape. The angle member 20a2 is provided so as to continue from the rail piece 25b toward the interior of the room. The interior end of the angle member 20a2 is fixed with screws 22 to the building frame or a frame attached to the frame.

[0018] Rails 24, 25 that protrude toward the inside of the frame are arranged side by side in the projection direction on the inner frame projection surface of the upper frame 12a. Rail 24 is a guide rail that guides the outer shoji screen 14 so that it can slide. Rail 24 is formed by rail piece 24a of the metal upper frame 18a and rail piece 24b of the resin upper frame 20a, and has a rectangular hollow shape. Rail 25 is a guide rail that guides the inner shoji screen 15 so that it can slide. Rail 25 is formed by rail piece 25a of the metal upper frame 18a and rail piece 25b of the resin upper frame 20a, and has a rectangular hollow shape. As a result, rails 24, 25 combine high thermal insulation performance with high appearance quality.

[0019] As shown in FIG. 2, the lower frame 12b is configured by connecting a resin lower frame 20b to a metal lower frame 18b fixed to the building frame with screws 22.

[0020] The metal lower frame 18b is configured to have improved thermal insulation performance by connecting the outdoor member 18b1 and the indoor member 18b2 with thermal insulation material 18b3. A rail piece 26a protrudes from the frame-inside visible surface of the outdoor member 18b1. A rail piece 27a protrudes from the frame-inside visible surface of the indoor member 18b2. The rail pieces 26a, 26b are aligned in the visible direction of the lower frame 12b. The metal lower frame 18b may be configured as a single member without using the thermal insulation material 18b3.

[0021] The resin lower frame 20b comprises an exterior-side member 20b1 and an interior-side member 20b2. The exterior-side member 20b1 is configured as a horizontal plate with an upwardly protruding rail piece 26b at its exterior end, and a pair of legs in the projection direction. These legs engage with the exterior-side member 18b1 of the metal lower frame 18b. The interior-side member 20b2 has a horizontal plate with an upwardly protruding rail piece 27b at its exterior end, and an angled portion 28 bent into a roughly L shape at the interior end of this horizontal plate. The interior-side member 20b2, like the exterior-side member 20b1, engages with the interior-side member 18b2 of the metal vertical frame 18c via a pair of legs in the projection direction. The angled portion 28 is fixed to the building frame or a frame attached to it with screws 22.

[0022] Rails 26, 27 that protrude toward the inside of the frame are arranged side by side in the projection direction on the inner frame projection surface of the lower frame 12b. Rail 26 is a guide rail that guides the outer shoji screen 14 so that it can slide. Rail 26 is formed by rail piece 26a of the metal lower frame 18b and rail piece 26b of the resin lower frame 20b, and has a rectangular hollow shape. Rail 27 is a guide rail that guides the inner shoji screen 15 so that it can slide. Rail 27 is formed by rail piece 27a of the metal lower frame 18b and rail piece 27b of the resin lower frame 20b, and has a rectangular hollow shape. Therefore, rails 26, 27 also combine high thermal insulation performance with high appearance quality.

[0023] As shown in Figure 3, the vertical frame 12c is located on the door edge side of the outer shoji screen 14 when it is in the fully closed position. The vertical frame 12c is configured by connecting a resin vertical frame 20c to a metal vertical frame 18c fixed to the building frame with screws 22.

[0024] The metal vertical frame 18c has a plate portion 30 and a rail piece 32a. The plate portion 30 extends in the indoor / outdoor direction and is fixed to the building frame with screws 22. The rail piece 32a protrudes from the frame inner projection surface 30a of the plate portion 30 toward the inside of the frame. The rail piece 32a is located closer to the outdoor side than the center in the projection direction of the frame inner projection surface 30a.

[0025] The resin vertical frame 20c has a base portion 34 and an angle portion 35. The base portion 34 extends in the indoor / outdoor direction and is fixed to the inner frame visible surface 30a of the metal vertical frame 18c with screws 22. The inner frame visible surface 34a of the base portion 34 is formed with a rail piece 32b that protrudes from its outer end toward the inside of the frame. The angle portion 35 is formed integrally with the inner end of the base portion 34 and is fixed with screws 22 to the building frame or a frame or the like fixed to the building frame.

[0026] A rail 32 protruding toward the inside of the frame is provided on the inner visible surface of the vertical frame 12c. The rail 32 supports the outer shoji screen 14 when it is in the fully closed position. The rail 32 is formed by a rail piece 32a of the metal vertical frame 18c and a rail piece 32b of the resin vertical frame 20c, and has a rectangular hollow shape. The rail pieces 32a and 32b engage with each other at the top surface 32c of the rail 32.

[0027] A cover member 36 is attached to the frame inner visible surface 34a of the base portion 34. The cover member 36 is an extruded shape made of a resin material such as PVC. The cover member 36 is attached to the resin vertical frame 20c so as to cover the frame inner visible surface of the base portion 34, and hides the heads of the screws 22 that connect the resin vertical frame 20c to the metal vertical frame 18c.

[0028] The cover member 36 is positioned so as to continue from the projection surface 35a of the angle portion 35, and has a projection surface 36a extending along the projection direction. The projection surface 36a is a substantially flat surface extending from a position adjacent to the angle portion 35 to a position close to the interior surface of the outer shoji screen 14. As a result, the projection surfaces 35a, 36a of the resin vertical frame 20c from the angle portion 35 to the cover member 36 are formed substantially flat, while at the same time narrowing the gap between the cover member 36 and the outer shoji screen 14, improving the appearance quality of the fitting 10. Furthermore, the cover member 36 hides the heads of the screws 22, further improving the appearance quality of the fitting 10.

[0029] The cover member 36 forms two hollows 37a, 37b between itself and the resin vertical frame 20c. The hollow 37a is arranged so as to be stacked inside the hollow 37c formed in the resin vertical frame 20c, and extends along the front-to-back direction. The hollow 37b extends in the front-to-back direction on the interior side of the hollows 37a, 37c. In this way, the three hollows 37a to 37c are arranged side by side in the front-to-back or front-to-back directions. As a result, the insulating performance of the vertical frame 12c, which is largely exposed to the interior on the interior side of the outer shoji screen 14, is improved, and condensation is also suppressed. The number of hollows formed in the resin vertical frame 20c and the cover member 36 may be any number other than three.

[0030] As shown in Figure 3, the vertical frame 12d is placed on the door edge side of the inner shoji screen 15 when it is in the fully closed position. The vertical frame 12d is configured by connecting a resin vertical frame 20d to a metal vertical frame 18d fixed to the building frame with screws 22.

[0031] The metal vertical frame 18d has a plate portion 38, a fin portion 39, and a rail piece 40a. The plate portion 38 extends in the indoor / outdoor direction and is fixed to the building frame with screws 22. The fin portion 39 protrudes inward from the frame inner projection surface 38a of the plate portion 38. The rail piece 40a protrudes inward from the frame inner side at a position on the indoor side of the fin portion 39 in the projection direction of the frame inner projection surface 38a.

[0032] The fin portion 39 faces the exterior surface 15a of the inner shoji screen 15 when it is in the fully closed position. The fin portion 39 has a pocket portion 39a that opens onto the exterior surface 15a. A thermally expandable member 41 can be installed in the pocket portion 39a. The thermally expandable member 41 is a member that expands when heated, such as a heat-expanding material such as graphite that expands when heated. By providing the thermally expandable member 41 in the pocket portion 39a, the building fixture 10 can fill the gap between the fin portion 39 and the inner shoji screen 15 in the event of a fire with the expanded thermally expandable member 41.

[0033] The resin vertical frame 20d has a rail piece 40b and an angle portion 42, and has a generally crank-shaped overall configuration. The rail piece 40b protrudes from the exterior end of the resin vertical frame 20d toward the inside of the frame. The angle portion 42 is a generally L-shaped portion formed at the interior end of the resin vertical frame 20d, and is fixed with screws 22 to the building frame or a frame or the like fixed to the building frame.

[0034] A rail 40 protruding toward the inside of the frame is provided on the inner visible surface of the vertical frame 12c. The rail 40 supports the inner shoji screen 15 when it is in the fully closed position. The rail 40 is formed by a rail piece 40a of the metal vertical frame 18d and a rail piece 40b of the resin vertical frame 20d, and has a rectangular hollow shape. The rail pieces 40a and 40b engage with each other at the top surface 40c of the rail 40.

[0035] As shown in Figures 1 to 3, the outer shoji screen 14 comprises a surface material 44, and an upper frame 45a, a lower frame 45b, a door edge frame 45c, and a joint frame 45d that surround the surface material 44 on all four sides.

[0036] The face material 44 is, for example, a double-layered glass having a pair of glass sheets 44a, 44b facing each other with a spacer sandwiched between them. The face material 44 may be a single layer, or may have a structure of three or more layers.

[0037] Each of the stiles 45a to 45d is an extruded profile made of a resin material such as PVC. Each of the stiles 45a to 45d has an opening groove 46 that opens toward the inside of the frame. The opening groove 46 holds the outer edge of the face material 44. Each of the stiles 45a to 45c, except for the joint stile 45d, has a guide groove 47 that opens toward the outside of the frame. The rail 24 of the upper frame 12a is slidably inserted into the guide groove 47 of the upper stile 45a. The rail 26 of the lower frame 12b is slidably inserted into the guide groove 47 of the lower stile 45b. The rail 32 of the vertical frame 12c is inserted into the guide groove 47 of the end stile 45c when the outer shoji screen 14 is in the fully closed position.

[0038] As shown in Figure 2, a door roller 48 is disposed on the lower frame 45b. The door roller 48 is a roller disposed in a guide groove 47 of the lower frame 45b, and rolls on a protrusion 26d protruding from the top surface 26c of the rail 26. As a result, the outer shoji screen 14 smoothly slides within the opening 16, with the guide grooves 47 of the upper and lower frames 45a, 45b being guided by the rails 24, 26. At this time, airtight and watertight materials 49 disposed within the guide grooves 47 of the frames 45a, 45b respectively slide against the visible surfaces on both the indoor and outdoor sides of each rail 24, 26. The airtight and watertight materials 49 are, for example, mohair or taupe.

[0039] In the fully closed position, the outer shoji screen 14 is held stably by the guide groove 47 of the door end frame 45c engaging the rail 32 of the opposing vertical frame 12c (see Figure 3). At this time, the airtight and watertight materials 49 installed in the guide groove 47 of the door end frame 45c come into contact with the visible surfaces of the rail 32 on both the indoor and outdoor sides.

[0040] As shown in Figures 1 to 3, the inner shoji screen 15 is slidably guided between the rail 25 of the upper frame 12a and the rail 27 of the lower frame 12b, and can move in a double sliding manner relative to the outer shoji screen 14. The inner shoji screen 15 may have a structure that is approximately symmetrical to the outer shoji screen 14, except for a slight difference in the configuration of the door frame 45d. Therefore, the components of the inner shoji screen 15 are given the same reference numerals as the components of the outer shoji screen 14, and detailed explanations will be omitted. In the fully closed position, the inner shoji screen 15 is stably held in place by the guide groove 47 of the door end frame 45c engaging the rail 40 of the opposing vertical frame 12d (see Figure 3). A protrusion 27d similar to the protrusion 26d of the rail 26 is also provided on the top surface 27c of the rail 27, and the door roller 48 of the inner shoji screen 15 rolls along it.

[0041] When both shoji screens 14 and 15 are in the fully closed position, their door frames 45d, 45d fit together (see Figure 3). At this time, the smoke deflectors 50 on the door frames 45d, 45d mesh with each other, and the airtight and watertight material 49 on the facing surface of one door frame 45d comes into contact with the opposing facing surface of the other door frame 45d. At this time, the crescent 52a on the door frame 45d of the inner shoji screen 15 can be engaged with the crescent receiver 52b on the door frame 45d of the outer shoji screen 14, allowing the shoji screens 14 and 15 to be locked.

[0042] As shown in Figures 4A and 4B, stopper members 54 and 55 are attached to ends 25A and 27A of the upper and lower rails 25 and 27 on the indoor side, respectively. As shown in Figures 5A and 5B, stopper members 56 and 57 are attached to ends 24A and 26A of the upper and lower rails 24 and 26 on the outdoor side, respectively.

[0043] The first stopper member 54 is an upper door stopper member that regulates the fully open position of the inner shoji screen 15, and is attached to the end 25A of the rail 25 on the vertical frame 12c side (see Figure 9C). The second stopper member 55 is a lower door stopper member that regulates the fully open position of the inner shoji screen 15, and is attached to the end 27A of the rail 27 on the vertical frame 12c side (see Figures 3 and 13B). The third stopper member 56 is an upper door stopper member that regulates the fully open position of the outer shoji screen 14, and is attached to the end 24A of the rail 24 on the vertical frame 12d side (see Figure 11C). The fourth stopper member 57 is a lower door stopper member that regulates the fully open position of the outer shoji screen 14, and is attached to the end 26A of the rail 26 on the vertical frame 12d side (see Figure 3). In this embodiment, the ends 24A, 25A, 26A, and 27A can be said to be within a predetermined distance from the small end faces of the rails 24 to 27, for example, within 10 cm.

[0044] The specific configuration of each of the rails 24 to 27 will be described.

[0045] 4A and 5A, rail 25 on the indoor side of upper frame 12a is configured such that rail piece 25a of metal upper frame 18a and rail piece 25b of resin upper frame 20a are engaged with engaging portion 58. Engagement portion 58 is located on indoor-facing surface 25d of rail 25, not on top surface 25c.

[0046] Rail piece 25a slopes from the interior toward the exterior toward its tip, then extends back toward the frame, bending again toward the interior and projecting toward the interior. This includes a bent portion 25a1 and a fin 25a2 projecting toward the interior from the inclined portion of bent portion 25a1. Rail piece 25b is bent like a right-angled claw and has a tip portion 25b1 that encompasses bent portion 25a1 of rail piece 25a. While encompassing bent portion 25a1, its tip engages with fin 25a2 (engagement portion 58). A resin cover piece 25e covers the base of rail piece 25a from engagement portion 58. Cover piece 25e is formed on angle member 20a2 of resin upper frame 20a. This allows the rail 25's exterior surface to be made almost entirely of resin, providing high thermal insulation and a high-quality appearance.

[0047] Rail 24 on the outdoor side of upper frame 12a is configured so that rail piece 24a of metal upper frame 18a and rail piece 24b of resin upper frame 20a are engaged with engaging portion 59. Engagement portion 59 is located on top surface 24c of rail 24. Engagement portion 59 is configured so that a hook-shaped claw portion formed on the indoor end of rail piece 24a, which is bent into an L shape, and opens toward the inside of the frame engages with a hook-shaped claw portion formed on the tip of rail piece 24b and opens toward the outside of the frame.

[0048] As shown in Figures 4B and 5B, the rail 27 on the indoor side of the lower frame 12b is configured such that rail piece 27a of the metal lower frame 18b and rail piece 27b of the resin lower frame 20b are engaged with each other at an engagement portion 60. Protrusion 27d is provided on the portion of rail piece 27a that forms top surface 26c. Protrusion 27d protrudes upward from the indoor-side end of rail piece 27a and has a generally mushroom-shaped cross section. Engagement portion 60 is disposed on top surface 27c of rail 27 and is adjacent to the indoor-side of protrusion 27d. Engagement portion 60 is configured such that a hook-shaped claw portion formed on the indoor-side end of rail piece 27a, which opens toward the inside of the frame, engages with a hook-shaped claw portion formed at the tip of rail piece 27b, which opens toward the outside of the frame.

[0049] The rail 26 on the exterior side of the lower frame 12b is configured such that rail piece 26a of the metal lower frame 18b and rail piece 26b of the resin lower frame 20b are engaged with each other at engagement portion 61. Protrusion 27d and engagement portion 61 may have substantially the same structure as protrusion 27d and engagement portion 60 on the interior side rail 27. In other words, protrusion 26d is provided on the interior side end of the portion that forms top surface 26c of rail piece 26a. Engagement portion 61 is located on top surface 26c, and is configured such that the hook-shaped claw portion of rail piece 26b engages with the hook-shaped claw portion of rail piece 26a.

[0050] Next, a description will be given of the configuration of the first stopper member 54 and the surrounding area of ​​the rail 25. First, the configuration of the first stopper member 54 will be described.

[0051] 6A to 8, the first stopper member 54 has a main body portion 54a, a recessed portion 54b, a groove portion 54c, a locking portion 54d, and a pair of engaging claws 54e, 54f. The first stopper member 54 is formed by injection molding of a resin material, for example, and the other stopper members 55 to 57 are molded in the same manner.

[0052] The main body 54a is formed in a roughly semi-cylindrical shape and has a rail cover portion 64 that covers the rail 25, and a protrusion 65 that protrudes from the rail cover portion 64 to the outside of the room and is disposed between the rails 24, 25 (see also Figures 9B and 9C). The visible surface 64a of the first stopper member 54 is formed on the rail cover portion 64 and has a slightly curved shape. The recess 54b is a portion of the visible surface 64a that is recessed one step lower on the edge side of the end portion 25A, i.e., the edge side of the vertical frame 12c, when the first stopper member 54 is attached to the rail 25.

[0053] The groove 54c extends along the longitudinal direction of the rail 25 inside the rail cover part 64. The groove 54c is a groove that opens facing the opposite side to the projection surface 64a, and also opens in a generally arch-like shape on the side surface 64b of the rail cover part 64. The groove 54c is formed so that its width in the projection direction is slightly larger than the width of the rail 25, allowing the rail 25 to be accommodated from the top surface 25c.

[0054] The locking portion 54d is provided adjacent to the back side of the groove portion 54c, that is, on the opposite side from the side surface 64b of the groove portion 54c. The locking portion 54d is a wall extending along the front direction and arranged like a dam to block the groove portion 54c. The locking portion 54d is the part that locks onto the rail 25 when the inner shoji screen 15's joining frame 45d collides with it.

[0055] The engaging claw portions 54e, 54f each have an elastic piece 66 protruding in the vertical direction from the back surface of the projection surface 64a, and a claw portion 67 formed at the tip of the elastic piece 66. The engaging claw portions 54e, 54f face each other across a distance substantially equal to the width dimension of the groove portion 54c in the projection direction, and the claw portions 67, 67 face each other. One of the engaging claw portions 54e has a tapered surface 67a on the side of the claw portion 67 facing the locking portion 54d. The tapered surface 67a is an inclined surface that gradually slopes the side of the claw portion 67 in the direction in which the claw portion 67 protrudes, gradually moving away from the locking portion 54d.

[0056] Next, the configuration of the end 25A of the rail 25 to which the first stopper member 54 is attached and its surrounding area will be described.

[0057] As shown in FIGS. 9A to 10A, rail 25 has a notch 70, an engagement hole 71, and an engagement protrusion 72 at end 25A.

[0058] The notch 70 is provided at a position a predetermined distance from the end face of the rail 25 on the vertical frame 12c side, and penetrates the rail 25 in the forward direction. The notch 70 has a generally U-shaped notch formed by cutting the rail pieces 25a, 25b from the top face 25c toward the outside of the frame, and opens toward the inside of the frame.

[0059] 10B, in the cutout portion 70, the cutout distance Lb of the resin rail piece 25b is greater than the cutout distance La of the metal rail piece 25a, relative to the longitudinal direction of the rail 25. As a result, the end face 70a of the rail piece 25a and the end face 70b of the rail piece 25b are arranged at different levels on the inner end face of the cutout portion 70 on the vertical frame 12c side. Specifically, the end face 70a of the metal rail piece 25a is positioned to protrude more inward than the end face 70b of the resin rail piece 25b. In the cutout portion 70 of this embodiment, the end faces of the rail pieces 25a, 25b are arranged to be approximately flush on the inner end face opposite the vertical frame 12c side.

[0060] As shown in Figures 9A, 9B, and 10A, the engagement hole 71 is a rectangular opening formed in the interior facing surface 25d of the rail 25. The engagement hole 71 is formed through the resin cover piece 25e. The engagement hole 71 is formed at a position closer to the small end surface of the end 25A than the cutout portion 70, based on the longitudinal direction of the rail 25. The engagement hole 71 is positioned further outside the frame than the engagement portion 58. The engagement claw portion 54e of the first stopper member 54 engages with the engagement hole 71.

[0061] 10A, the engagement protrusion 72 is a claw-shaped protrusion formed on the exterior facing surface 25f of the rail 25. The engagement protrusion 72 is formed on the resin rail piece 25b and extends along the longitudinal direction of the rail 25. The engagement protrusion 72 is provided at approximately the same position as the engagement hole 71 in the height direction of the rail 25. The engagement protrusion 72 is engaged with the engagement claw portion 54f of the first stopper member 54.

[0062] Next, the structure for attaching and detaching the first stopper member 54 to the rail 25 and its function and effect will be described.

[0063] 9B, the operation of attaching the first stopper member 54 begins by moving the first stopper member 54 from bottom to top, and inserting the rail 25 into the groove 54c from the top surface 25c. Then, the locking portion 54d of the first stopper member 54 is inserted into the notch 70, and the engaging claw portion 54f on the exterior side engages with the engaging protrusion 72 (see FIG. 10A).

[0064] Next, the first stopper member 54 is slid toward the small end face of the end portion 25A along the longitudinal direction of the rail 25. Then, while the engagement between the engagement claw 54f and the engagement protrusion 72 is maintained, the indoor-side engagement claw 54e now engages laterally with the engagement hole 71 (see FIG. 10A). At this time, the recess 54b is inserted into the gap G1 formed between the upper end surface 36b of the cover member 36 attached to the vertical frame 12c and the rail 25. In other words, the upper end of the cover member 36 is accommodated in the recess 54b.

[0065] In this way, the first stopper member 54 is attached to the rail 25. In this attached state, the first stopper member 54 covers the notch 70, the engagement hole 71, the gap G, and the upper end surface 36b (see FIGS. 9C and 10A). Therefore, the fitting 10 has a high appearance quality.

[0066] When the first stopper member 54 is attached to the rail 25, the locking portion 54d is inserted into the notch 70 and is inserted through the rail 25 in the forward direction (see FIG. 10B). At this time, in the notch 70, the end face 70a of the metal rail piece 25a protrudes further inward than the end face 70b of the resin rail piece 25b. Therefore, when the first stopper member 54 is attached by sliding along the rail 25, the locking portion 54d comes into contact with or close to the end face 70a.

[0067] Therefore, when the inner screen 15 is fully opened and the crosspiece 45d impacts the side surface 64b of the first stopper member 54, the metal end surface 70a of the rail 25 engages the locking portion 54d. As a result, even though the door fixture 10 is configured to have enhanced thermal insulation performance by using a resin upper frame 20a for the upper frame 12a, the impact when the inner screen 15 impacts the first stopper member 54 is prevented from being directly transmitted to the resin rail piece 25b, thereby suppressing damage to the resin upper frame 20a. Furthermore, the first stopper member 54 is configured so that the locking portion 54d abuts against the metal rail piece 25a, which is less susceptible to thermal effects than resin. Therefore, even if the resin rail piece 25b expands or contracts due to thermal effects, the first stopper member 54 can suppress misalignment or detachment from the installation position.

[0068] Furthermore, the length Lc of the locking portion 54d of the first stopper member 54 in the longitudinal direction of the rail 25 is smaller than the notch distance La of the notch 70 (see FIG. 10B ). Therefore, when the first stopper member 54 is attached to the rail 25, a gap G2 is formed between the locking portion 54d and the end face of the notch 70 opposite the end face 70a. The length of the gap G2 in the longitudinal direction of the rail 25 is preferably equal to or greater than the length of the recessed portion 54b inserted into the gap G1. This ensures that the first stopper member 54 has a sufficient sliding distance along the longitudinal direction of the rail 25 when the locking portion 54d is inserted into the notch 70. As a result, the recessed portion 54b of the first stopper member 54 can be smoothly inserted and removed from the gap G1, facilitating attachment and detachment of the first stopper member 54 to and from the rail 25.

[0069] 9B, the removal operation of first stopper member 54 can be the reverse of the above-described installation operation. That is, first stopper member 54 is first slid in a direction away from end portion 25A along the longitudinal direction of rail 25. Then, indoor-side engagement claw 54e is removed from engagement hole 71 while the engagement state between engagement claw 54f and engagement protrusion 72 is maintained.

[0070] At this time, the claw portion 67 of the engaging claw portion 54e has a tapered surface 67a on the side surface on the leading side in the direction of removal from the engaging hole 71. Therefore, the tapered surface 67a of the first stopper member 54 smoothly slides on the edge of the engaging hole 71, and the claw portion 67 can be easily removed from the engaging hole 71. As a result, the first stopper member 54 can avoid a situation in which the side surface of the claw portion 67 gets caught on the edge of the engaging hole 71, preventing the claw portion 67 from being smoothly removed from the engaging hole 71, making the removal operation easier.

[0071] After the engaging claw portion 54e has disengaged from the engaging hole 71, the first stopper member 54 can be moved from top to bottom to remove the groove portion 54c from the rail 25. At this time, the elastic piece 66 of the engaging claw portion 54f on the outdoor side elastically deforms, allowing the claw portion 67 to smoothly disengage from the engaging protrusion 72. In this way, the first stopper member 54 is removed from the rail 25.

[0072] Next, the configuration of the third stopper member 56 and the rail 24 in its surrounding area will be described.

[0073] The third stopper member 56 has a configuration that is mostly the same as or similar to the above-described first stopper member 54. For this reason, in the following, for the third stopper member 56, elements that have the same or similar functions and effects as the first stopper member 54 will be given the same reference numerals and detailed descriptions thereof will be omitted, and the same applies to the subsequent stopper members 54 and 57.

[0074] 5A, 11B, and 11C, the third stopper member 56 differs from the first stopper member 54 in that it does not have a recess 54b, but has a slit-shaped recess 65a in the protrusion 65. Therefore, the third stopper member 56 also has a main body portion 54a in which the rail cover portion 64 and the protrusion 65 are provided, a groove portion 54c, a locking portion 54d, and engaging claw portions 54e and 54f. Note that the engaging claw portion 54e of the third stopper member 56 does not have a tapered surface 67a.

[0075] As shown in FIGS. 11A and 11B, the rail 24 to which such a third stopper member 56 is attached has a notch 74, an engagement hole 75, and an engagement protrusion 76 at an end 24A.

[0076] The cutout portion 74 may have substantially the same structure as the cutout portion 70 of the rail 25 described above. That is, in the cutout portion 74 as well, the cutout distance of the resin rail piece 24b is greater than the cutout distance of the metal rail piece 24a, based on the longitudinal direction of the rail 25. As a result, in the cutout portion 74 as well, the end face 78a of the rail piece 24a is arranged in a stepped manner, projecting further inward than the end face 78b of the rail piece 24b, on the inner end face on the vertical frame 12d side.

[0077] 11B, the engagement hole 75 is a rectangular opening formed on the exterior-facing surface of the rail 24. The engagement hole 75 is formed through the metal rail piece 24a. The engagement hole 75 is formed in a position closer to the small end surface of the end 24A than the notch 74, based on the longitudinal direction of the rail 24. The engagement claw 54e of the third stopper member 56 engages with the engagement hole 75.

[0078] As shown in Fig. 11A, the engagement protrusion 76 is a claw-shaped protrusion formed on the interior facing surface of the rail 24. The engagement protrusion 76 is formed on the resin rail piece 24b and extends along the longitudinal direction of the rail 24. The engagement protrusion 76 is provided slightly outside the frame than the engagement hole 75 in the height direction of the rail 24. The engagement protrusion 76 engages with the engagement claw portion 54f of the third stopper member 56.

[0079] Next, the structure for attaching and detaching the third stopper member 56 to the rail 24 and its function and effect will be described.

[0080] 11B and 11C, no cover member 36 is provided on the vertical frame 12d on the end 24A side of the rail 24. Therefore, to attach the third stopper member 56, which does not have the recess 54b, it is sufficient to move the third stopper member 56 from bottom to top and insert the rail 24 into the groove 54c from the top surface 24c. When this is done, the locking portion 54d of the third stopper member 56 is inserted into the notch 74, the engaging claw 54e on the exterior side engages with the engaging hole 75, and the engaging claw 54f on the interior side engages with the engaging protrusion 76 (see also FIG. 5A).

[0081] In this manner, the third stopper member 56 is attached to the rail 24. In this attached state, the third stopper member 56 covers the notch 74 and the engagement hole 75, just as in the case of the first stopper member 54. Furthermore, by inserting the fin portion 39 into the recess 65a, the third stopper member 56 also covers the gap between the upper end surface of the fin portion 39 and the upper frame 12a. Therefore, the fitting 10 has a high appearance quality.

[0082] Furthermore, in the third stopper member 56, the locking portion 54d inserted into the notch 74 abuts or is close to the end face 78a of the metal rail piece 24a. Therefore, even though the fitting 10 is configured to have enhanced thermal insulation performance using a resin upper frame 20a, the impact when the outer sash 14 collides with the third stopper member 56 is prevented from being directly transmitted to the resin rail piece 24b, thereby suppressing damage to the resin upper frame 20a. Of course, the third stopper member 56 can also be prevented from shifting in its mounting position or falling off due to expansion and contraction of the resin material, and similar effects can be obtained for the other stopper members 55 and 57.

[0083] 11B, the removal operation of the third stopper member 56 can be performed by reversing the procedure of the above-described installation operation. That is, by simply pressing the third stopper member 56 downward, the elastic pieces 66 of the engagement claws 54e, 54f are elastically deformed outward, and the third stopper member 56 is released from the engagement hole 75 and the engagement protrusion 76. In this way, the third stopper member 56 does not need to slide in the longitudinal direction of the rail 24 during the removal operation, and the engagement claw 54e can be smoothly removed from the engagement hole 75 by the elastic deformation of the elastic piece 66. For this reason, the third stopper member 56 is configured so that the engagement claw 54e does not have a tapered surface 67a.

[0084] Next, the configuration of the second stopper member 55 and the rail 27 in its surrounding area will be described.

[0085] 12A, 12B, and 13B, the second stopper member 55 has a substantially vertically symmetrical structure to the first stopper member 54, except that the second stopper member 55 does not have the recessed portion 54b and the protruding portion 65, and the main body portion 54a is provided with the connecting portion 80 and the cover portion 81. Therefore, the second stopper member 55 also has the main body portion 54a provided with the rail cover portion 64, the groove portion 54c, the locking portion 54d, and the engaging claw portions 54e and 54f.

[0086] The connecting portion 80 is a vertical wall-like portion provided on one side of the curved, arc-shaped visible surface 64a and having a flat surface along the visible direction. The cover portion 81 is a wall panel that protrudes diagonally rearward from the outdoor side of the connecting portion 80.

[0087] As shown in FIG. 13A, the rail 27 to which such a second stopper member 55 is attached has a notch 84, an engagement hole 85, and an engagement protrusion 86 at an end 27A.

[0088] The cutout 84 has a structure similar to the cutout 70 of the rail 25 described above. That is, in the cutout 84, the cutout distance of the resin rail piece 27b is greater than the cutout distance of the metal rail piece 27a, based on the longitudinal direction of the rail 27. However, the rail 27 has a structure in which the resin rail piece 27b itself has been removed from the fore-end face of the end 27A of the end portion 27A, leaving only the metal rail piece 27a. Therefore, only the end face 88 of the rail piece 27a is positioned at the inner end face of the cutout 84 on the vertical frame 12c side.

[0089] The engagement hole 85 is a rectangular opening formed on the exterior-facing surface of the rail 27. The engagement hole 85 is formed through the metal rail piece 27a. The engagement hole 85 is formed in a position closer to the small end surface of the end 27A than the notch 84, based on the longitudinal direction of the rail 27. The engagement claw 54e of the second stopper member 55 engages with the engagement hole 85.

[0090] The engagement protrusion 86 is a claw-shaped protrusion formed on the interior facing surface of the rail 27. In this embodiment, the lower surface of the hook-shaped claw portion that forms the engagement portion 60 of the rail piece 27a also serves as the engagement protrusion 86 (see FIG. 4B). The engagement protrusion 86 is provided slightly inside the frame than the engagement hole 75 in the height direction of the rail 27. The engagement protrusion 86 is engaged with the engagement claw portion 54f of the second stopper member 55.

[0091] Next, the structure for attaching and detaching the second stopper member 55 to the rail 27 and its function and effect will be described.

[0092] 13A and 13B, the attachment and detachment operation of the second stopper member 55 is substantially the same as that of the first stopper member 54, except that it is upside down. That is, the second stopper member 55 is first moved from top to bottom to insert the rail 27 into the groove portion 54c from the top surface 27c. Then, the second stopper member 55 has the locking portion 54d inserted into the notch 84, and the interior-side engagement claw portion 54f engages with the engagement protrusion 86 (see FIG. 4B).

[0093] Next, the second stopper member 55 is slid toward the small end face of the end portion 27A along the longitudinal direction of the rail 27. Then, while the engagement between the engagement claw portion 54f and the engagement protrusion 86 is maintained, the exterior engagement claw portion 54e now engages with the engagement hole 85 (see also FIG. 4B). At this time, the connecting portion 80 is positioned so as to fill the gap formed between the lower end surface 36c of the cover member 36 attached to the vertical frame 12c and the frame interior visible surface 90 of the lower frame 12b.

[0094] In this way, the second stopper member 55 is attached to the rail 27. In this attached state, the second stopper member 55 covers the notch 84, the engagement hole 85, the bottom end face 36c, and the gap between the bottom end face 36c and the frame inner visible surface 90. Therefore, the fitting 10 has a high appearance quality.

[0095] Furthermore, in the second stopper member 55, the locking portion 54d inserted into the notch 84 abuts or comes close to the end face 88 of the metal rail piece 24a. Therefore, even though the fitting 10 is configured to have improved heat insulation performance by using a resin lower frame 20b for the lower frame 12b, it is possible to prevent the impact when the inner shoji screen 15 collides with the second stopper member 55 from being directly transmitted to the resin rail piece 27b, thereby suppressing damage to the resin lower frame 20b.

[0096] The removal operation of the second stopper member 55 can be performed by reversing the procedure of the above-described installation operation, and therefore a detailed description thereof will be omitted. As in the case of the first stopper member 54, when the second stopper member 55 is removed, the engagement claw portion 54e is smoothly removed from the engagement hole 85 by the action of the tapered surface 67a.

[0097] 12A, 12B, and 13B, the second stopper member 55 has multiple drainage recesses 92 on the lower end surface of the outer peripheral wall on the outdoor side and the groove portion 54c side. When the second stopper member 55 is attached to the rail 27, the drainage recesses 92 form drainage holes that communicate with the outdoor side between the second stopper member 55 and the frame inner surface 90 of the lower frame 12b. This allows rainwater and the like that accumulates on the frame inner surface 90 of the lower frame 12b to be smoothly drained to the outdoor side through these drainage holes.

[0098] 3 and 5B, the configuration of the fourth stopper member 57 and its mounting structure on the rail 26 can be roughly the upside-down configuration of the third stopper member 56 and its mounting structure on the rail 24, so a detailed description will be omitted. Note that the end 26A of the rail 26 to which the fourth stopper member 57 is attached is on the outside of the inner shoji screen 15, in an area where the resin lower frame 20b is not attached. Therefore, the fourth stopper member 57 can be attached to the rail piece 26a of the metal lower frame 18b.

[0099] In the above, an example has been shown in which the stopper members 54 to 57 have slightly different configurations, but for example, the stopper members 55 to 57 may have the same or symmetrical structure as the first stopper member 54, and the same applies to the rails 24 to 27.

[0100] In the above, the first stopper member 54 has been exemplified as having the engaging holes 71 and the engaging protrusions 72 on its indoor and outdoor facing surfaces 25d, 25f, but the engaged portions with which the engaging claws 54e, 54f engage may be configured with only one of the engaging holes 71 and the engaging protrusions 72, and the same may be true for the other stopper members 55 to 57. In this case, it is sufficient to use only one of the engaging claws 54e, 54f.

[0101] As described above, the fitting according to the first aspect of the present invention comprises an opening frame having a vertical frame and a horizontal frame, a shoji screen that is guided by a rail formed on the horizontal frame and slidably supported on the opening frame, and a stopper member that is attached to the end of the rail and regulates the full open position of the shoji screen, and the horizontal frame has a metal horizontal frame having a first rail piece and a second rail piece that engages with the first rail piece to form the rail, and a resin horizontal frame that is connected to the metal horizontal frame so as to cover the visible frame inner surface of the metal horizontal frame, and the rail is formed on the first rail piece and the second rail piece. The stopper member has a groove into which the rail is inserted and which straddles the rail, a locking portion inserted into the notch and which passes through the rail in the projecting direction, and an engaging claw portion which can be engaged with and disengaged from the locking portion. The notch is formed such that the distance of the notch in the second rail piece made of resin is greater than the distance of the notch in the first rail piece made of metal, based on the longitudinal direction of the rail, so that the locking portion of the stopper member is locked with the end surface of the first rail piece. With this configuration, the locking portion of the stopper member that collides when the shoji screen is fully opened is locked with the end surface of the first metal rail piece within the notch. As a result, while the fitting has a resin frame material for the horizontal frame to enhance thermal insulation performance, the impact when the shoji screen collides with the stopper member is not directly transmitted to the resin rail piece, thereby suppressing damage to the resin frame material.

[0102] The engaged portion may include an engagement hole formed on a first visible surface of the rail, the engaging claw portion may include a first claw portion that engages with the engagement hole and is prevented from coming off in the vertical direction, and the first claw portion may have a tapered surface on a side surface facing away from the end portion with respect to the longitudinal direction of the rail. In this way, when the stopper member is slid in the longitudinal direction of the rail perpendicular to the vertical direction, which is the engagement direction, with the first claw portion engaged with the engagement hole, the first claw portion can be smoothly released from the engagement hole.

[0103] The engaged portion may further include an engaging protrusion formed on a second visible surface of the rail, the engaging claw portion may include a second claw portion that engages with the engaging protrusion to prevent it from coming off in the vertical direction, the second rail piece may be provided to cover the first rail piece, and the engaging hole and the engaging protrusion may be formed on the second rail piece. In this case, the rail has a configuration in which a metal first rail piece is covered by a resin second rail piece, further improving heat insulation performance.

[0104] Furthermore, a resin cover member may be provided that is attached to the vertical frame so as to cover the inner visible surface of the vertical frame located on the end side of the rail, and that forms a hollow portion extending along the visible direction between the vertical frame and the cover member, and a recess that accommodates the end of the cover member may be provided on the visible surface of the stopper member. In this way, the insulating performance and appearance quality of the vertical frame are improved by the cover member, and the appearance quality is further improved by hiding the end by the recess of the stopper member.

[0105] The length of the notch may be greater than the length of the locking portion relative to the longitudinal direction of the rail, and when the locking portion is inserted into the notch, a gap of a length equal to or greater than the length of the recess relative to the longitudinal direction of the rail is secured in the notch. In this way, when the locking portion is inserted into the notch, the stopper member can ensure a sufficient sliding distance along the longitudinal direction of the rail, making it easier to attach and detach the stopper member to and from the rail.

[0106] It should be noted that the present invention is not limited to the above-described embodiment, and can be freely modified without departing from the spirit of the present invention. [Explanation of symbols]
