Description

[Technical Field]

[0001] The present invention relates to a fitting having a lower frame and a shoji screen that can slide in the longitudinal direction of the lower frame while being guided by a rail provided on the lower frame. [Background technology]

[0002] In fittings such as sliding windows, the shoji screen slides along a rail attached to the bottom frame, and drainage holes are often provided in the rail or bottom frame to prevent water from accumulating in the bottom frame (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-139842 Summary of the Invention [Problem to be solved by the invention]

[0004] From a design standpoint, it is desirable that the drain holes described above be as inconspicuous as possible, and it is particularly desirable that they be configured so that they are not visible from the indoor side, which is the living space.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a fixture that has a drainage opening to prevent water from accumulating in the sill, while still providing a pleasant interior appearance. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems and achieve the object, the fitting of the present invention is a fitting having a lower frame and a shoji screen that is guided by a rail provided on the lower frame and can slide in the longitudinal direction of the lower frame, the rail being constructed by engaging an outdoor rail member including an outdoor sight wall with an indoor rail member including an indoor sight wall, the indoor sight wall of the indoor rail member having a drainage opening formed in it that communicates with the hollow formed between the outdoor rail member and the indoor rail member, and the drainage opening is characterized in that at least its upper part is provided with a stopper that the shoji screen comes into contact with when it is fully closed or when the shoji screen is fully open. [Effects of the Invention]

[0007] In the fittings of the present invention, a drain opening is formed to prevent water from accumulating in the sill. A fully closed shoji screen or stopper is placed above the drain opening, so it is not visible from inside the room, at least when the shoji screen is fully closed. Furthermore, because the drain opening is formed on the visible wall on the inside of the room, it is hardly visible from a person's perspective diagonally above, even when the shoji screen is open, providing a pleasant interior view.

[0009] Hereinafter, an embodiment of the fittings according to the present invention will be described in detail with reference to the drawings, however, the present invention is not limited to the embodiment.

[0010] Fig. 1 is a view of a fitting 10 according to this embodiment as seen from inside the room. Fig. 2 is a horizontal cross-sectional view of the fitting 10. Fig. 3 is a vertical cross-sectional view of the lower part of the fitting 10 at the location of the wind stop board 42 and a location to the left of the wind stop board 42. Fig. 4 is a vertical cross-sectional view of the lower part of the fitting 10 at a location to the right of the wind stop board 42.

[0011] As shown in Figures 1 and 2, the fitting 10 according to this embodiment comprises an opening frame 12 fixed to an opening in a building frame, and two left and right shoji screens, an outer shoji screen 14 and an inner shoji screen 15, which are slidably arranged inside the opening frame 12. In this embodiment, a sliding window fitting 10 is exemplified, in which an opening 16 formed inside the opening frame 12 can be opened and closed by sliding the shoji screens 14 and 15. The shoji screens 14 and 15 may be single-sliding windows, with one screen fitted into the opening frame 12 and the other screen sliding. The number of shoji screens installed may be three or more. The shoji screens 14 and 15 in Figures 1 and 2 are in a fully closed state. The arrows in Figure 1 indicate the opening direction of each shoji screen 14 and 15.

[0012] The opening frame 12 forms a rectangular opening 16 by framing all four sides with an upper frame 18, a lower frame 20, and left and right vertical frames 22, 23. Each of the frames 18-22 is an extruded metal material, such as aluminum, or an extruded resin material, such as polyvinyl chloride (PVC). In this application, aluminum material includes alloy materials. Each of the frames 18-22 may have a composite structure, in which a resin frame material is attached to the interior side of a metal frame material, such as an aluminum-resin composite frame. Of these, the lower frame 20 is an aluminum-resin composite frame, which will be described later. The opening frame 12 is fixed to the building frame using fasteners 25, such as screws or nails (see Figure 3).

[0013] In this application, the "visible direction" refers to the indoor / outdoor direction of the fitting 10, i.e., the direction from the inside of the room to the outside, or the opposite direction, 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 vertical frames 22, 23, etc. that are long in the vertical direction, it refers to the left-right direction that is perpendicular to their longitudinal direction, and in the case of bottom frames 20, etc. that are long in the horizontal direction, it refers to the up-down direction that is perpendicular to their longitudinal direction. The "visible surface" refers to a surface along the visible direction. Furthermore, "left" and "right" are based on the state as seen from the inside of the room, i.e., the state shown in Figures 1 and 2.

[0014] As shown in Figure 3, the lower frame 20 has an outer rail 24 and an inner rail 26 aligned in the front direction. The rails 24, 26 protrude inward (upward) from the front surface of the inside of the frame of the lower frame 20 and extend the entire length of the lower frame 20. The outer rail 24 slidably guides the outer shoji screen 14 on the outside of the room. The inner rail 26 slidably guides the inner shoji screen 15.

[0015] The upper frame 18 also has a similar rail provided on the inner surface of the frame so as to face the rails 24, 26. The vertical frames 22, 23 are connected to the frames 18, 20 so as to cover the fore-end faces of the frames 18, 20 (see Figures 1 and 2).

[0016] The outer shoji screen 14 is made up of an upper frame 28a, a lower frame 28b, a door edge frame 28c, and a joint frame 28d surrounding the screen, and a panel 30 placed on the inside. The panel 30 is a double-glazed glass panel with a pair of glass panes 30a, 30b arranged facing each other at a distance, for example, via a spacer.

[0017] Each of the frames 28a to 28d may be made of a single extruded metal or resin material, or may have a composite structure made of an extruded metal material such as aluminum and an extruded resin material such as vinyl chloride resin.

[0018] As shown in Figures 3 and 4, the lower frame 28b has an opening groove 32 on its lower projection surface that accommodates the outer rail 24, and a surface material placement groove 33 on its upper projection surface that accommodates the lower edge of the surface material 30. The opening groove 32 protrudes downward from the projection surface of the lower frame 28b and is formed between a pair of hanging pieces 32a, 32b that are aligned in the projection direction. The surface material placement groove 33 is formed between a pair of protruding pieces formed on the lower frame 28b. The other frame stiles 28a, 28c, and 28d also have their respective surface material placement grooves 33 that accommodate the upper edge or side edge of the surface material 30.

[0019] A sealant 34a protrudes from the lower end of the outdoor-side hanging piece 32a toward the indoor side, and a sealant 34b protrudes from the lower end of the indoor-side hanging piece 32b toward the outdoor side. The sealants 34a and 34b are held in place by pockets formed at the lower ends of the hanging pieces 32a and 32b. The sealants 34a and 34b are positioned opposite each other, sandwiching the vicinity of the upper end of the outer rail 24 to provide airtight and watertight sealing between the outdoor and indoor sides. The outer rail 24 is contacted by the sealants 34a and 34b from both the indoor and outdoor sides, providing a good balance. The sealants 34a and 34b are not necessarily completely waterproof or airtight, but may have some degree of airtightness and waterproofness. The sealants 34a and 34b are, for example, mohair. The sealant 34b abuts against the side of the hook portion 54b at the engagement point between the hook portion 24ad and the hook portion 54b, as described below.

[0020] The roller 17 of the outer shoji screen 14 is rotatably supported by the lower frame 28b, and its lower part is positioned in the opening groove 32. The roller 17 rolls on the outer rail 24, allowing the outer shoji screen 14 to slide smoothly relative to the opening frame 12.

[0021] The inner shoji screen 15 can slide in a double-sliding manner relative to the outer shoji screen 14 by the rollers 17 rolling on the inner rail 26 of the lower frame 20. The inner shoji screen 15 may have the same or similar structure as the outer shoji screen 14. Therefore, for the inner shoji screen 15, the same reference numerals are used for components corresponding to those of the outer shoji screen 14 described above, and detailed explanations will be omitted. The joint frame 28d of the inner shoji screen 15 and the joint frame 28d of the outer shoji screen 14 can be locked by a crescent 36 (see Figure 1), thereby keeping the shoji screens 14, 15 in a closed state.

[0022] In this embodiment, when the outer shoji screen 14 is in the leftmost position in Figures 1 and 2, the door end frame 28c abuts against the vertical frame 22 and is in a fully closed state, and when the inner shoji screen 15 is in the rightmost position, the door end frame 28c abuts against the vertical frame 23 and is in a fully closed state. A stopper 38 is provided at the rightmost part of the outer rail 24, which limits the movement of the door frame 28d when the outer shoji screen 14 is fully open. A stopper 40 is provided at the leftmost part of the inner rail 26, which limits the movement of the door frame 28d when the inner shoji screen 15 is fully open.

[0023] A wind stop plate 42 (see Figure 7) is attached to the approximate center of the visible surface of the sill 20. The wind stop plate 42 is a resin part that closes the gap between the rails 24, 26, prevents water and wind from entering the room through the gap between the joining parts of the shoji screens 14, 15, i.e., the gap between the joining frames 28d, 28d, and maintains airtightness and watertightness between the inside and outside of the room.

[0024] The lower frame 20 will be described in more detail below. As shown in Figures 3 and 4, the sill 20 is constructed by connecting an outdoor lower sill 44 and an indoor lower sill 46 via filler material 48. The outdoor lower sill 44 and the indoor lower sill 46 are both made of aluminum. Pockets 47a, 47b that hold the filler material 48 are formed where the outdoor lower sill 44 and the indoor lower sill 46 face each other. The filler material 48 is a type of resin material and prevents heat transfer between the outdoor lower sill 44 and the indoor lower sill 46.

[0025] The exterior lower frame 44 has an upper wall 44a, a lower wall 44b, an exterior wall 44c, and an interior wall 44d, and these four walls form a lower cavity 44e with a slightly larger cross-sectional area. The portion of the upper wall 44a closest to the interior of the room is slightly inclined downward toward the exterior, but the portion near the outer rail 24 is horizontal.

[0026] The outdoor rail member 24a extends upward from a location slightly outside the room from the center of the upper wall 44a in the forward direction. The outdoor rail member 24a is made of aluminum and is integral with the upper wall 44a. The outdoor rail member 24a has a standing wall 24aa that forms the outdoor visible wall of the outer rail 24, a bent portion 24ab that protrudes slightly toward the room from the upper end of the standing wall 24aa, a roller receiving portion 24ac that protrudes slightly upward from the bent portion 24ab, and a hook portion 24ad provided at the tip of the bent portion 24ab. The hook portion 24ad is located close to the indoor side and at a lower position than the roller receiving portion 24ac, and is shaped to open upward. The top of the roller receiving portion 24ac is semicircular.

[0027] A screw hole 44f is provided on the underside of the upper wall 44a near a location below the protruding point of the outdoor rail member 24a. A small positioning piece 44g that protrudes upward is provided on the upper surface of the upper wall 44a at a location slightly inside the room from the protruding point of the outdoor rail member 24a. A fixing piece 44h is provided at the lower part of the outdoor bottom frame 44 at the indoor end for fixing to the frame with the fixing device 25. The upper wall 44a extends to the outside while bending slightly downward from the point where it is connected to the outdoor rail member 24a, and a screen rail 44i is erected upward from the outdoor end.

[0028] The indoor-side lower frame 46 has a projection plate 46a, an indoor-side sight plate 46b, and a middle lower plate 46c. The indoor-side sight plate 46b intersects with the indoor-side end of the projection plate 46a to form a T-shape and is in surface contact with the frame. The middle lower plate 46c protrudes downward from approximately the middle of the projection plate 46a, with its tip abutting the stepped surface of the frame. A pocket 47b is provided below the outdoor-side end of the projection plate 46a. An outdoor rail member 26a extends upward from the outdoor-side end of the projection plate 46a. The outdoor rail member 26a has a standing wall 26aa, a bent portion 26ab, a roller receiving portion 26ac, and a hook portion 26ad, which correspond to the standing wall 24aa, bent portion 24ab, roller receiving portion 24ac, and hook portion 24ad of the outdoor rail member 24a. The roller receiving portion 24ac and the roller receiving portion 26ac are at the same height. A small positioning piece 46d that protrudes upward is provided on the upper surface of the projection plate 46a at a location slightly inside the room from the protruding part of the outdoor rail member 26a. The positioning piece 46d has the same shape as the positioning piece 44g described above.

[0029] The exterior lower frame 44 is provided with a first attachment 50 (see Figure 3) and a second attachment 52 (see Figure 4). The first attachment 50 and the second attachment 52 are separated by the location of the wind stopper plate 42 (in other words, the location facing the joining frame 28d of the outer shoji screen 14 and the inner shoji screen 15 in the fully closed state), with the first attachment 50 on the left and the second attachment 52 on the right. The first attachment 50 is made of resin, and the second attachment 52 is made of aluminum. The attachments 50, 52 and a third attachment 60, which will be described later, are extruded members configured to have a substantially uniform cross section along their entire length.

[0030] As shown in FIG. 3, the first attachment 50 includes a projection plate 50a, an indoor lower plate 50b, an outdoor lower plate 50c, and a first indoor rail member 54. The projection plate 50a is positioned slightly above the positioning piece 44g so as to abut the outdoor surface of the outdoor rail member 26a. A small gap may be provided between the projection plate 50a and the outdoor rail member 26a. The projection plate 50a is slightly inclined downward toward the outdoor side. The indoor lower plate 50b protrudes from the underside of the projection plate 50a and abuts the upper surface of the upper wall 44a. The tip of the indoor lower plate 50b has a protrusion facing the indoor side, which snap-fits into a protrusion formed in the pocket 47a. The outdoor lower plate 50c protrudes downward from the outdoor end of the projection plate 50a and abuts the upper surface of the upper wall 44a. The tip of the outdoor lower plate 50c has a protrusion facing the outdoor side, which is engaged in a snap-fit ​​manner with a protrusion formed on the positioning piece 44g.

[0031] The first indoor-side rail member 54 extends upward from the end of the projection panel 50a. The first indoor-side rail member 54 has a standing wall 54a and a hook portion 54b. The standing wall 54a and the outdoor lower panel 50c are in a straight line and intersect with the outdoor end of the projection panel 50a to form a T. The hook portion 54b is located on the outdoor side of the upper end of the standing wall 54a and has a shape that opens downward.

[0032] The hook portions 24ad and 54b are engaged with each other through their recesses and protrusions, so that the outdoor rail member 24a and the first indoor rail member 54 form approximately the left half of the outer rail 24. A first upper hollow portion 55a is formed between the standing wall 24aa and the standing wall 54a. The first attachment 50 is positioned so that the outdoor lower frame 44 and filler material 48 are not visible from the indoor side. The first attachment 50 has a suitable design, for example, a wood grain finish.

[0033] The space surrounded by the projection plate 50a, the indoor-side lower plate 50b, the outdoor-side lower plate 50c, and the upper wall 44a constitutes a second upper cavity 55b. The space surrounded by the projection plate 50a, the indoor-side lower plate 50b, the outdoor rail member 26a, the pocket 47a, and the filler 48 constitutes a third upper cavity 55c.

[0034] As shown in Figure 4, the second attachment 52 has a projection plate 52a, an indoor lower plate 52b, an outdoor lower plate 52c, and a second indoor rail member 56. The projection plate 52a corresponds to the projection plate 50a in the first attachment 50, but protrudes slightly shorter toward the indoor side than the projection plate 50a, and does not abut against the outdoor surface of the outdoor rail member 26a, ensuring a gap 58. The second attachment 52 is made of aluminum and has high thermal conductivity, but is thermally insulated because the gap 58 is provided, and heat is not transferred between the outdoor lower frame 44 and the indoor lower frame 46.

[0035] The indoor-side lower plate 52b and the outdoor-side lower plate 52c have the same shape as the indoor-side lower plate 50b and the outdoor-side lower plate 50c, and their lower ends engage with the side of the pocket 47a and the positioning piece 44g. The second indoor-side rail member 56 has substantially the same shape as the first indoor-side rail member 54, and has a standing wall 56a and a hook portion 56b.

[0036] The hook portion 24ad and the hook portion 56b are engaged with each other, so that the exterior rail member 24a and the second interior rail member 56 form approximately the right half of the exterior rail 24. A first upper cavity 55a is formed between the vertical wall 24aa and the vertical wall 56a. The second attachment 52 is not visible from the interior side when the inner screen 15 is fully closed, so no special design treatment is required. The second attachment 52 is made of aluminum, which has better weather resistance than plastic materials and is less susceptible to deterioration even when placed in a location exposed to the outside air and sunlight.

[0037] As shown in Fig. 3, a third attachment 60 is provided on the indoor side lower frame 46. The third attachment 60 is provided over the entire longitudinal length of the indoor side lower frame 46. The third attachment 60 is made of a resin material and has the same color, pattern, and texture as the first attachment 50 described above.

[0038] The third attachment 60 has a projection plate 60a, an indoor lower plate 60b, an outdoor lower plate 60c, a frame abutment piece 60d, and a third indoor rail member 62. The third indoor rail member 62 forms the indoor portion of the inner rail 26.

[0039] The frame abutment piece 60d has an angled shape with a visible portion and a visible portion that fits along the corner of the frame, and the visible portion is fixed to the frame with a fastener 25. The visible portion of the frame abutment piece 60a extends from a position slightly above the positioning piece 46d to the end of the frame abutment piece on the exterior side of the room. The visible portion of the frame abutment piece 60a is slightly inclined downward toward the exterior side of the room. The indoor lower plate 60b protrudes downward from the indoor end of the visible portion of the frame abutment piece 60a, with its tip abutting the upper surface of the visible portion of the frame abutment piece 46a. The tip of the indoor lower plate 60b has a protrusion facing the interior side, which snap-fits with the protrusion formed on the indoor visible portion of the frame abutment piece 46b. The outdoor lower plate 60c protrudes downward from the outdoor end of the visible portion of the frame abutment piece 46a, with its tip abutting the upper surface of the visible portion of the frame abutment piece 46a. The tip of the outdoor lower plate 60c has a protruding portion facing the outdoor side, which is engaged in a snap-fit ​​manner with a protruding portion formed on the positioning piece 46d.

[0040] The third indoor-side rail member 62 extends upward from the upper end of the projection plate 60a. The third indoor-side rail member 62 has the same shape as the first indoor-side rail member 54, and has a standing wall 62a and a hook portion 62b. The standing wall 62a and the outdoor lower plate 60c are in a straight line and intersect with the outdoor end of the projection plate 60a to form a T. The hook portion 62b is located on the outdoor side of the upper end of the standing wall 62a and has a shape that opens downward.

[0041] The hook portions 26ad and 62b are engaged with each other through their recesses and protrusions, thereby forming the inner rail 26 between the outdoor rail member 26a and the third indoor rail member 62. A fourth upper cavity 55d is formed between the standing wall 26aa and the standing wall 62a. A fifth upper cavity 55e is formed in the space surrounded by the projection plate 60a, the indoor lower plate 60b, the outdoor lower plate 60c, and the projection plate 46a.

[0042] The lower frame 20 has a first upper cavity 55a formed in the outer rail 24 and a fourth upper cavity 55d formed in the inner rail 26, improving thermal insulation. The lower frame 20 has an interior groove 64 with the projection board 60a as its bottom and the standing wall 62a and the interior lower board 60b as its opposite walls; an intermediate groove 66 with the projection board 50a as its bottom and the standing wall 54a and the standing wall 26aa as its opposite walls; and an exterior groove 68 with the upper wall 44a as its bottom and the screen rail 44i and the standing wall 24aa as its opposite walls. Rain can seep into the exterior groove 68 via the exterior shoji screen 14. Water can also seep into the interior groove 64 and the intermediate groove 66 during cleaning with water, etc.

[0043] The fitting 10 is formed with drainage openings for draining water that seeps into these grooves 64, 66, and 68 to the outside of the room. These drainage openings will be described below. Note that the term "drainage opening" in this application refers to any shape that allows for drainage, and includes hole-shaped and notch-shaped openings. In the following description, to avoid complication, both hole-shaped and notch-shaped openings will be referred to as "drainage openings." Each drainage opening is provided to connect the upstream space (usually the indoor space) and the downstream space (usually the outdoor space) with the wall as a boundary, allowing for drainage. Furthermore, each drainage opening is provided as low as possible in the wall to prevent water from accumulating upstream.

[0045] Three first drainage openings 70a, the lower edges of which reach the recessed panel 60a, are provided in the upright wall 62a, which is the indoor-side visible wall of the third indoor-side rail member 62 of the inner rail 26. One of the first drainage openings 70a is provided at the left end (see FIG. 8, also referred to as first drainage opening 70aa), one at the right end (see FIG. 8, also referred to as first drainage opening 70ab), and the remaining one at the center (see FIG. 8, also referred to as first drainage opening 70ac). In other words, the first drainage openings 70a are provided only at both left and right ends (both longitudinal ends of the inner rail 26) and the center. The first drainage opening 70aa is notched, and the first drainage openings 70ab and 70ac are hole-shaped.

[0046] Second drainage openings 70b, the lower edges of which reach the recessed panel 46a, are provided in the upright wall 26aa, which is the outdoor sight wall of the outdoor rail member 26a of the inner rail 26. Two second drainage openings 70b are provided near the left end of the inner rail 26, and two are provided in approximately the center.

[0047] A third drain opening 70c, the lower edge of which reaches the recessed panel 50a, is provided in the upright wall 54a, which is the indoor-side visible wall of the first indoor-side rail member 54 in the roughly left half of the outer rail 24. The third drain opening 70c is provided near the left and right ends of the first indoor-side rail member 54.

[0048] A fourth drain opening 70d (see Figure 10) is provided in the outdoor lower plate 50c of the first attachment 50. A fifth drain opening 70e (see Figure 10) is provided in the indoor lower plate 50b of the first attachment 50. There are two drain openings 70d, 70e, and they are located slightly closer to the center than the third drain opening 70c. The drain openings 70d, 70e have a notched shape that opens downward. The fourth drain opening 70d and the fifth drain opening 70e are located opposite each other and each have an appropriate width.

[0049] Sixth drain openings 70f, the lower edges of which reach the recessed panel 52a, are provided in the upright wall 56a, which is the outdoor sight wall of the second indoor rail member 56 in the roughly right half of the outer rail 24. Two sixth drain openings 70f are provided near each of the left and right ends of the second indoor rail member 56.

[0050] A seventh drain opening 70g (see Figure 11) is provided in the outdoor lower plate 52c of the second attachment 52. An eighth drain opening 70h (see Figure 11) is provided in the indoor lower plate 52b of the second attachment 52. There are two drain openings 70g, 70h, and they are located slightly closer to the center than the sixth drain opening 70f. The drain openings 70g, 70h have a notched shape that opens downward. The seventh drain opening 70g and the eighth drain opening 70h are located opposite each other and each has an appropriate width.

[0051] Four drain openings, namely, a ninth drain opening 70i, a tenth drain opening 70j, an eleventh drain opening 70k, and a twelfth drain opening 70m, are provided in the exterior-side lower frame 44 of the lower frame 20. The ninth drain openings 70i are provided in a left-right direction in a position on the top wall 44a near the first drain opening 70aa. The tenth drain openings 70j are provided in the vertical wall 24aa of the exterior rail member 24a in four positions corresponding to the sixth drain opening 70f (see FIG. 8), and are located below the sixth drain opening 70f in the forward direction.

[0052] The eleventh drain opening 70k is provided near both left and right ends of the screen rail 44i. The twelfth drain opening 70m is provided near both left and right ends of the exterior wall 44c. The eleventh drain opening 70k and the twelfth drain opening 70m are sections through which water that has flowed into the grooves 64, 66, and 68 of the sill 20 is ultimately drained to the outside of the room. A drain valve 71 is provided in the twelfth drain opening 70m.

[0053] A notch 75 is formed near the right end of the outdoor rail member 24a for positioning and fixing the stopper 38. A notch 77 is formed near the left end of the outdoor rail member 26a for positioning and fixing the stopper 40. A notch 81 is formed near the right end of the positioning piece 46d. The notch 81 is a type of drain opening, but is not for main drainage but for draining water that has entered the fifth upper hollow portion 55e.

[0054] As shown in Fig. 8, the lower end of the vertical frame 22 and the edge of the lower frame 20 are fixed with a plurality of screws 87 via a packing 85. The lower end of the vertical frame 23 is fixed to the edge of the lower frame 20 in a similar manner. Reference numeral 98 in Fig. 8 denotes an insect-proof block, and reference numeral 97 denotes a component mounting hole for attaching the insect-proof block 98. As shown in Fig. 5, legs 40a are provided at the four corners of the lower end of the stopper 40, and gaps 40b are formed between the areas other than the legs 40a and the projection plates 50a, 60a.

[0055] Fig. 12 is a schematic diagram illustrating the drainage path at the location to the left of the wind stop plate 42. Fig. 13 is a schematic diagram illustrating the drainage path at the location to the right of the wind stop plate 42. In Figs. 13 and 13A, each drainage opening is shown on the same cross section for ease of understanding.

[0056] The first drain opening 70a connects the indoor groove 64 to the fourth upper cavity 55d. The second drain opening 70b connects the fourth upper cavity 55d to the third upper cavity 55c. The third drain opening 70c connects the intermediate groove 66 to the first upper cavity 55a. The fourth drain opening 70d connects the first upper cavity 55a to the second upper cavity 55b. The fifth drain opening 70e connects the third upper cavity 55c to the second upper cavity 55b. The sixth drain opening 70f connects the intermediate groove 66 to the first upper cavity 55a. The seventh drain opening 70g connects the first upper cavity 55a to the second upper cavity 55b. The eighth drain opening 70h connects the third upper cavity 55c to the second upper cavity 55b. The ninth drain opening 70i connects the second upper cavity 55b to the lower cavity 44e. The tenth drain opening 70j connects the first upper cavity 55a to the outdoor groove 68. The eleventh drain opening 70k connects the outdoor groove 68 to the outdoor space. The twelfth drain opening 70m connects the lower cavity 44e to the outdoor space.

[0057] The second drainage opening 70b is hole-shaped. The third drainage opening 70c is hole-shaped. The fourth drainage opening 70d is notch-shaped. The fifth drainage opening 70e is notch-shaped. The sixth drainage opening 70f is hole-shaped. The seventh drainage opening 70g is notch-shaped. The eighth drainage opening 70h is notch-shaped. The ninth drainage opening 70i is hole-shaped. The tenth drainage opening 70j is hole-shaped. The eleventh drainage opening 70k is hole-shaped. The twelfth drainage opening 70m is hole-shaped. Also, as described above, the first drainage opening 70aa is notch-shaped, and the first drainage openings 70ab and 70ac are hole-shaped. Each drainage opening may be either hole-shaped or notch-shaped.

[0058] As shown by the dashed line as route R1, water that enters the indoor gutter 64 passes through the first drain opening 70a into the fourth upper cavity 55d, the second drain opening 70b into the third upper cavity 55c, the fifth drain opening 70e into the second upper cavity 55b, the ninth drain opening 70i into the lower cavity 44e, and is discharged outside through the twelfth drain opening 70m. Note that water that enters the indoor gutter 64 flows directly into the first drain openings 70ab and 70ac on the right and center, but flows into the first drain opening 70aa on the left side after passing through the gap 40b (see FIG. 5).

[0059] As shown by the dashed line as path R2, water that enters the intermediate groove 66 in the area where the first attachment 50 is installed flows through the third drainage opening 70c into the first upper cavity 55a, through the fourth drainage opening 70d into the second upper cavity 55b, through the ninth drainage opening 70i into the lower cavity 44e, and is discharged outside the room through the twelfth drainage opening 70m.

[0060] In addition, in path R2, the only path from the outside to the inside of the room is where water enters the second upper cavity 55b through the fourth drain opening 70d. It is conceptually possible to provide a drain opening on the bottom of the first upper cavity 55a to connect it to the lower cavity 44e directly below. However, the first upper cavity 55a has a narrow projected width and is surrounded by screw holes 44f and positioning pieces 44g. Therefore, from the perspective of processing and strength, it is not practical to provide a drain opening. Therefore, water is drained through the fourth drain opening 70d, first via the second upper cavity 55b and the ninth drain opening 70i, and then into the lower cavity 44e. In path R2, a flow from the outside to the inside of the room occurs. However, the upper wall 44a, which forms the bottom of the second upper cavity 55b, is horizontal around the ninth drain opening 70i, so it does not obstruct drainage.

[0061] As shown by the dashed line as path R3 (see FIG. 13), water that enters the intermediate groove 66 in the area where the second attachment 52 is provided passes through the sixth drain opening 70f into the first upper cavity 55a, the tenth drain opening 70j into the exterior groove 68, and is discharged to the outdoors through the eleventh drain opening 70k. Note that, as shown by the dashed line as path R4, water that enters the intermediate groove 66 in the area where the second attachment 52 is provided can pass from the first upper cavity 55a through the seventh drain opening 70g into the second upper cavity 55b, the ninth drain opening 70i into the lower cavity 44e, and is discharged to the outdoors through the twelfth drain opening 70m.

[0062] In addition, water that enters the intermediate groove 66 in the area where the second attachment 52 is provided can pass through the gap 58 into the third upper hollow portion 55c, through the eighth drainage opening 70h into the second upper hollow portion 55b, through the seventh drainage opening 70g into the first upper hollow portion 55a, through the ninth drainage opening 70i into the outdoor groove 68, and be discharged outside the room through the eleventh drainage opening 70k, as shown by the dashed line as path R5.

[0063] Furthermore, water that enters the intermediate groove 66 in the area where the second attachment 52 is provided can pass through the gap 58 into the third upper cavity 55c, through the eighth drain opening 70h into the second upper cavity 55b, through the ninth drain opening 70i into the lower cavity 44e, and be discharged outside the room through the twelfth drain opening 70m, as shown by the dashed line as route R6.

[0064] 12, if the water accumulates in the fourth upper hollow portion 55d and cannot be drained, it may enter the fifth upper hollow portion 55e through a gap or the like. The water that enters the fifth upper hollow portion 55e in this way passes through the notch 81 (see FIG. 8) into the fourth upper hollow portion 55d, passes through the second drainage opening 70b into the third upper hollow portion 55c, and then follows the same path as paths R5 and R6 before being drained. In other words, this path passes through the fourth upper hollow portion 55d twice.

[0065] As shown by the dashed line as route R7, water that enters the exterior groove 68 is discharged to the outside through the eleventh drain opening 70k. In this way, in the fitting 10, proper drainage is achieved through the drain openings 70a to 70m, and water does not accumulate in the grooves 64, 66, and 68.

[0066] Figure 14 is a schematic diagram showing the location of the drain opening in the sill 20. In Figure 14, some components are shown only with imaginary lines or outlines, and the drain opening is hatched so that the location of the drain opening can be seen. In Figure 14, the shoji screens 14 and 15 are in a fully closed position, just like in Figures 1 and 2.

[0067] With respect to the inner rail 26, the first drain opening 70aa at the left end is covered and not visible because a stopper 40 is disposed above it. The first drain openings 70ab and 70ac at the right end and center are covered at least above them by the door edge frame 28c or the door joint frame 28d of the fully closed inner shoji screen 15. Strictly speaking, the first drain openings 70ab and 70ac are not covered from the sides, but because the door edge frame 28c and the door joint frame 28d have a certain amount of visibility, they are not actually visible from diagonally above, which is the viewpoint of people inside the room.

[0068] Furthermore, with respect to the outer rail 24, the third drain opening 70c at the left end and approximately in the center is covered by placing the door edge frame 28c or the door joint frame 28d of the fully closed outer shoji screen 14 at least in its upper portion. As with the first drain opening 70a, the side portions of the third drain opening 70c are not covered, but since the door edge frame 28c and the door joint frame 28d have a certain amount of visibility, they are not actually visible from diagonally above, which is the viewpoint of people inside the room, and a pleasant interior view can be obtained.

[0069] Furthermore, with regard to the outer rail 24, the sixth drain opening 70f at the right end and approximately in the center is located outside the room relative to the inner shoji screen 15 when it is fully closed, and therefore can be seen through the glass panel 30a of the inner shoji screen 15 from diagonally above, which is the viewpoint of people inside the room.However, in reality, it is a recessed, dark location, and is hardly noticeable due to reflections and glare, maintaining a pleasant interior appearance.

[0070] In normal use, the shoji screens 14, 15 are almost always fully closed, so the first drain openings 70ab, 70ac and the third drain opening 70c are almost never visible. Also, the first drain opening 70a, the third drain opening 70c and the sixth drain opening 70f are covered by the shoji screens 14, 15 or the stopper 40 located in the upper part, so foreign objects are unlikely to get caught in them, and the sliding operation of the shoji screens 14, 15 is unlikely to be hindered.

[0071] The first drain openings 70ab, 70ac, the third drain opening 70c, and the sixth drain opening 70f can be seen when the shoji screens 14, 15 are open, but because they are provided in the vertical walls 62a, 54a, 56a that form the sight walls, they are hardly visible from diagonally above compared to when they are formed in the sight boards 60a, 50a, 52a. Also, when the drain openings 70 are provided in the vertical walls 62a, 54a, 56a that form the sight walls, they are less likely to become clogged with foreign matter than when they are formed in the sight boards 60a, 50a, 52a, and there is no interference with drainage.

[0072] The first drain openings 70ab, 70ac, the third drain opening 70c, and the sixth drain opening 70f are provided at a relatively low position in the upright walls 62a, 54a, 56a, ensuring a sliding margin for the sealant 34b (see FIG. 3) at a relatively high position. Because the shoji screens 14, 15 have the sealant 34b, they necessarily have a certain amount of width toward the inside of the room, making the first drain openings 70ab, 70ac, the third drain opening 70c, and the sixth drain opening 70f even more difficult to see.

[0073] The rails 24, 26 have the outdoor rail member and the indoor rail member engaged at their tops, forming a first upper cavity 55a and a fourth upper cavity 55d that provide thermal insulation. When the inner shoji screen 15 is closed, the first attachment 50 is included in the indoor space, but because the first attachment 50 is made of resin, it provides thermal insulation from the outdoors even when engaged with the outdoor rail member 24a. Because the attachments 50, 60 included in the indoor space are made of resin, they can be subjected to various surface treatments, resulting in excellent design.

[0074] On the other hand, the second attachment 52 is included in the outdoor space, but as mentioned above, the second attachment 52 is made of aluminum and has excellent weather resistance. A gap 58 is secured between the second attachment 52 and the outdoor rail member 26a, providing thermal insulation between them. For the sake of convenience in this description, the attachments 50, 52, and 60 are described as members attached to the lower frame 20, but they may also be considered as components of the lower frame 20.

[0075] The present invention is not limited to the above-described embodiment, and can of course be freely modified within the scope of the gist of the present invention.

[0076] The fixture of the present invention is a fixture having a lower frame and a shoji screen that can slide in the longitudinal direction of the lower frame while being guided by a rail provided on the lower frame, the rail being constructed by engaging an outdoor rail member including an outdoor sight wall with an indoor rail member including an indoor sight wall, the indoor sight wall of the indoor rail member having a drainage opening formed in it that communicates with the hollow formed between it and the outdoor rail member, and the drainage opening has a stopper disposed at least above it that abuts against the shoji screen when it is fully closed or when the shoji screen is fully open.

[0077] In such fittings, drainage openings are formed to prevent water from accumulating in the sill. The drainage openings are covered by a fully closed shoji screen or stopper placed above them, so they are not visible, at least when the shoji screen is fully closed. Furthermore, because the drainage openings are formed on the interior wall, they are hardly visible from a person's perspective diagonally above, even when the shoji screen is open, allowing for a pleasant interior view.

[0078] In the fitting according to the present invention, an interior sealing material of the shoji screen may be in contact with the interior side visible wall. The sealing material provides airtightness and watertightness.

[0079] The exterior rail member may be made of aluminum and integral with the lower frame, and the interior rail member may be a resin attachment attached to the lower frame. This resin-aluminum composite structure provides favorable strength, design, and thermal insulation.

[0080] In the fittings of the present invention, the rails include two rails, an inner rail on the indoor side and an outer rail on the outdoor side, the shoji screens include two rails, an inner shoji screen guided by the inner rail and an outer shoji screen guided by the outer rail, the outdoor rail member of the outer rail is made of aluminum material integral with the lower frame, the indoor rail member of the outer rail is an attachment attached to the lower frame, and the closed side of the outer shoji screen, with a boundary at a point facing the joint of the outer shoji screen in a fully closed state, may be made of resin material and the open side may be made of aluminum material. In this way, by using resin material and aluminum material for the outer rail depending on the location, strength, design, and insulation properties according to the application area can be obtained.

[0081] In the fittings of the present invention, the rails include two rails, an inner rail on the indoor side and an outer rail on the outdoor side, the shoji screens include two rails, an inner shoji screen guided by the inner rail and an outer shoji screen guided by the outer rail, and the drainage openings of the indoor rail member of the inner rail may be provided only at both longitudinal ends and the center of the indoor rail member. In this way, the drainage opening at one longitudinal end can be covered with a stopper, and the other two can be covered by the inner shoji screen 15 of the inner rail in its closed state.
