Modes for Carrying Out the Invention

[0009] Hereinafter, preferred embodiments of the fitting according to the present invention will be given and described in detail with reference to the accompanying drawings.

[0010] As shown in FIGS. 1 to 3, a fitting 10 according to one embodiment includes a frame body 12 fixed to an opening of a building body, a shoji 14 rotatably supported inside the frame body 12, and a screen door 15 installed on the indoor side of the shoji 14. In the present embodiment, a fitting 10 of a protruding window in which the shoji 14 rotates with the upper edge as a rotation fulcrum so that the lower edge protrudes toward the outdoor side is exemplified. The fitting 10 is, for example, a smoke exhaust window installed in a building or a house. The fitting according to the present application may be, for example, an outward-opening window, a sliding window, a vertical sliding window, etc. other than the protruding window, and may be used for applications other than the smoke exhaust window.

[0011] The frame body 12 is formed by assembling an upper frame 12a, a lower frame 12b, and left and right vertical frames 12c and 12d into a four-sided frame, with a rectangular opening 16 formed inside.

[0012] In this application, the prospective direction refers to the indoor-outdoor direction of the fitting 10, that is, the direction from the indoor side to the outdoor side or the reverse direction (the direction indicated by the arrow Z in the figure), and the prospective plane refers to the plane extending along the prospective direction. The finding direction is the direction orthogonal to the prospective direction. In the case of a vertically long vertical frame 12c or the like, it refers to the left-right direction orthogonal to its longitudinal direction (the direction indicated by the arrow X in the figure), and in the case of a horizontally long upper frame 12a or the like, it refers to the up-down direction orthogonal to its longitudinal direction (the direction indicated by the arrow Y in the figure). The finding plane refers to the plane along the finding direction. The inside of the frame refers to the inner part of the frame member such as the frame body 12, and the outside of the frame refers to the outer part of the frame member such as the frame body 12.

[0013] The frame body 12 is a window frame with a composite structure combining a metal frame material 18 arranged on the outdoor side and a resin frame material 19 arranged on the indoor side. The metal frame material 18 is an extruded profile of a metal material such as an aluminum alloy. The resin frame material 19 is an extruded profile of a resin material such as vinyl chloride resin (PVC). The metal frame material 18 includes a metal upper frame 18a, a metal lower frame 18b, and left and right metal vertical frames 18c and 18d. The resin frame material 19 includes a resin upper frame 19a, a resin lower frame 19b, and left and right resin vertical frames 19c and 19d.

[0014] As shown in FIG. 2, the upper frame 12a has a configuration in which a resin upper frame 19a is connected to the indoor side of the metal upper frame 18a. The resin upper frame 19a covers the indoor side surface of the metal upper frame 18a. The metal upper frame 18a has a predetermined anchor component connected to an anchor attachment portion 20 formed on the prospective plane on the outside of the frame, and is fixed to the building body through this anchor component. The resin upper frame 19a is connected to the metal upper frame 18a by, for example, a pair of engaging portions 22a and 22b, and the indoor side end is fixed to the building body with screws.

[0015] The metal upper frame 18a is provided with a door stop piece 26 at the indoor side end of the prospective surface 24 inside the frame, and a water drainage member 27 is attached to the outdoor side end of the prospective surface 24. The door stop piece 26 is a plate piece protruding from the prospective surface 24 toward the inside (downward) of the frame. The door stop piece 26 is a portion that receives the shoji 14 in the fully closed position shown in FIG. 2. A pocket portion that opens toward the outdoor side is provided at the tip of the door stop piece 26, and a tight material 28 is attached to this pocket portion. The tight material 28 is an airtight and watertight material for ensuring the airtightness and watertightness in the indoor-outdoor direction of the opening 16 by closely adhering to the indoor side surface of the shoji 14. The water drainage member 27 is attached to a pocket portion formed in the prospective surface 24 and opening downward, and can contact the upper end of the shoji 14. A metal plate 26a is fixed to the outdoor side finding surface of the door stop piece 26. The metal plate 26a substantially increases the weight and thickness of the door stop piece 26 and enhances the sound insulation performance and fire prevention performance of the fitting 10.

[0016] The resin upper frame 19a covers the surface of the door stop piece 26 of the metal upper frame 18a and the surface of the portion on the indoor side thereof. The resin upper frame 19a has a hollow portion 29 at a position aligned with the indoor side of the door stop piece 26.

A metal plate 34a is also fixed to the outdoor-side finding surface of the door stop piece 34. Similar to the above-described metal plate 26a, the metal plate 34a enhances the sound insulation performance and fire prevention performance of the fitting 10.

[0019] The resin lower frame 19b covers the upper end surface of the door stop piece 34 of the metal lower frame 18b and the portion on the indoor side thereof. The lower frame 12b has a hollow portion 35 formed by the metal lower frame 18b and the resin lower frame 19b on the indoor side of the door stop piece 34. A part of the wall portion surrounding the hollow portion 35 is formed by the metal lower frame 18b, and the rest is formed by the resin lower frame 19b.

[0020] As shown in FIG. 2, the upper frame 12a further has an upper attachment member 36 attached to the indoor side of the upper frame body (the metal upper frame 18a and the resin upper frame 19a). The lower frame 12b further has a lower attachment member 37 attached to the indoor side of the lower frame body (the metal lower frame 18b and the resin lower frame 19b). The specific configurations of the attachment members 36 and 37 will be described later.

[0021] As shown in FIG. 3, one vertical frame 12c has a configuration in which a resin vertical frame 19c is connected to the indoor side of a metal vertical frame 18c. The resin vertical frame 19c covers the indoor-side surface of the metal vertical frame 18c. A predetermined anchor component is connected to an anchor attachment portion 38 formed on the prospective surface outside the frame of the metal vertical frame 18c, and is fixed to the building body via this anchor component. The resin vertical frame 19c is connected to the metal vertical frame 18c by, for example, a pair of engagement portions 40a and 40b, and the indoor-side end is fixed to the building body with screws.

[0022] The metal vertical frame 18c is provided with a door-stop piece 44 at the indoor-side end of the prospective surface 42 inside the frame. The door-stop piece 44 is a plate piece protruding inward from the prospective surface 42 into the frame. The door-stop piece 44 is a portion that receives the shoji 14 in the fully closed position shown in Fig. 3. A pocket portion that opens toward the outdoor side is provided at the tip of the door-stop piece 44, and the tight material 28 is attached to this pocket portion. A metal plate 44a is also fixed to the outdoor-side finding surface of the door-stop piece 44. Similar to the above-described metal plate 26a, the metal plate 44a enhances the sound insulation performance and fire prevention performance of the fitting 10.

[0023] The resin vertical frame 19c covers the surface of the door-stop piece 44 of the metal vertical frame 18c and the surface of the portion on the indoor side thereof. The resin vertical frame 19c has a hollow portion 45 at a position aligned with the indoor side of the door-stop piece 44.

[0024] As shown in Fig. 3, the other vertical frame 12d can have a structure symmetrical to that of the one vertical frame 12c. Therefore, the same reference numerals are given to the respective components of the vertical frame 12d as those of the respective components of the vertical frame 12c, and detailed description thereof is omitted. That is, also in the vertical frame 12d, the resin vertical frame 19d is connected to the metal vertical frame 18d by the engaging portions 40a and 40b. Further, the vertical frame 12d also has a door-stop piece 44 to which the tight material 28 is attached at the indoor-side end of the prospective surface 24, and the resin vertical frame 19d has a hollow portion 45.

[0025] As shown in Figs. 1 to 3, the shoji 14 includes a face material 46, a frame body 47 that surrounds the four circumferences of the face material 46, and a pressing edge 48.

[0026] The face material 46 is, for example, a two-layer laminated glass in which a pair of plate glasses 46a and 46b are opposed to each other with spacers interposed therebetween. The face material 46 may be a single layer or may have a structure of three or more layers.

[0027] The frame body 47 supports the facing material 46 inside by forming a four-sided frame with the upper frame 47a, the lower frame 47b, and the left and right vertical frames 47c and 47d. On the outer side end of the prospective surface 50 inside the frames 47a to 47d, there are finding pieces 51 provided. The finding piece 51 is a plate piece protruding from the prospective surface 50 to the inside of the frame. The finding piece 51 is the part that supports the outer surface of the facing material 46 on the outdoor side.

[0028] The frames 47a to 47d are extruded profiles made of a metal material such as an aluminum alloy. In this embodiment, the upper frame 47a and the lower frame 47b have a vertically symmetric structure, and the vertical frames 47c and 47d have a horizontally symmetric structure. The frames 47a to 47d may each have a different cross-sectional shape, or all the frames 47a to 47d may have the same cross-sectional shape.

[0029] The edge press 48 is respectively mounted on the indoor side of the prospective surfaces 50 of each of the frames 47a to 47d. The edge press 48 is the part that supports the inner surface of the facing material 46 on the indoor side. The facing material 46 is held via a gasket, a sealing material, etc. in a state where the four peripheral edges are inserted into the opening groove formed by the finding piece 51, the edge press 48, and the prospective surface 50.

[0030] The edge press 48 includes a metal edge press 48a and a resin edge press 48b. The metal edge press 48a is an extruded profile made of a metal material such as an aluminum alloy. The resin edge press 48b is an extruded profile made of a resin material such as vinyl chloride resin (PVC). The metal edge press 48a is connected to the prospective surfaces 50 of the frames 47a to 47d using the engaging portion 54. The resin edge press 48b is connected to the metal edge press 48a and the prospective surface 50 by a pair of engaging portions 55a and 55b. The edge press 48 is configured to simultaneously hold the inner surface of the facing material 46 with the metal edge press 48a and the resin edge press 48b arranged in the frame inner and outer direction.

[0031] As shown in FIG. 3, the shoji screen 14 is pivotally connected to the frame body 12 via a hinge 60. The hinge 60 is connected to the prospective surface 24 inside the frame of the upper frame 12a and the prospective surface 58 outside the frame of the upper sash 47a. The reference numeral 61 in FIG. 2 is a wire-type shoji screen opening / closing device that is spanned between the lower sash 47b and the lower frame 12b and is operated by a predetermined operation handle to open and close the shoji screen 14. The reference numeral 62 in FIG. 4 is a stay damper that controls the opening / closing torque of the shoji screen 14 with respect to the frame body 12.

[0032] The reference numeral 63 in FIGS. 2 and 3 is a thermally expandable member. The thermally expandable member 63 is a heat-expandable material such as graphite that foams and expands when heated, for example, and is appropriately installed at various locations on the sash 47. The metal plates 26a, 34a, 44a provided on the frame body 12 may be replaced with the thermally expandable member 63.

[0033] As shown in FIGS. 1 to 3, the screen door 15 includes a screen door frame 64 and a screen body 65 stretched inside the screen door frame 64. The screen door 15 is a FIX screen door that is supported by the frame body 12 in a non-openable / closable manner.

[0034] The screen door frame 64 supports the screen body 65 inside by forming a four-sided frame with an upper frame (screen door upper frame) 64a, a lower frame (screen door lower frame) 64b, and left and right vertical frames (screen door vertical frames) 64c, 64d. The frames 64a to 64d are extrusion-molded products of a metal material such as an aluminum alloy or an extrusion-molded product of a resin material such as polyvinyl chloride resin (PVC). In the present embodiment, the frames 64a to 64d have the same cross-sectional shape. The frames 64a to 64d have a square tube portion 68 and a screen support portion 69. The square tube portion 68 is a portion outside the frame that forms the edge of the screen door 15. The screen support portion 69 is provided so as to protrude from the prospective surface inside the frame of the square tube portion 68, and a substantially U-shaped portion that supports the screen body 65 is provided at the tip.

[0035] The screen body 65 is a mesh formed of metal fine wires such as stainless steel or resin fine wires such as polypropylene. The screen body 65 is supported and stretched around the screen door frame 64.

[0036] As shown in Fig. 2, the screen door 15 is supported by the frame body 12 such that the upper frame 64a, which is the upper edge portion, is supported by the upper attachment member 36, and the lower frame 64b, which is the lower edge portion, is supported by the lower attachment member 37. Further, the screen door 15 can be supported by the resin vertical frames 19c and 19d, which are the side edge portions.

[0037] Next, the support structure of the screen door 15 and the function and effect of the fitting 10 will be specifically described.

[0038] First, the members that support the screen door 15 will be described. As shown in Fig. 4, the resin upper frame 19a has an indoor side wall portion 70 of the hollow portion 29 and a fin portion 71 that protrudes indoors from the upper part of the finding surface 70a on the indoor side of the wall portion 70. The fin portion 71 can also be used as a portion fixed to the building body with screws.

[0039] The upper attachment member 36 is fixed to the wall portion 70 via a connecting fitting 72. The connecting fitting 72 is a sheet metal part formed by bending a metal plate such as steel or stainless steel into an L shape. The connecting fitting 72 is attached at appropriate intervals at a plurality of locations in the longitudinal direction of the resin upper frame 19a. The connecting fitting 72 has a first plate portion 72a along the vertical direction and a second plate portion 72b bent indoors from the lower end of the first plate portion 72a. The first plate portion 72a is brought into contact with the finding surface 70a and fixed to the wall portion 70 with screws 75 using the back plate 74 in the hollow portion 29. As a result, the second plate portion 72b is installed so as to protrude indoors from the finding surface 70a.

[0040] The upper attachment member 36 has an attachment piece 36a, a protruding piece 36b, and a cover piece 36c. The upper attachment member 36 is an extruded shape made of a metal material such as an aluminum alloy, for example.

[0041] The mounting piece 36a is arranged along the indoor-outdoor direction and is fixed to the lower surface of the second plate portion 72b of the connecting fitting 72 with screws 76. The protruding piece 36b is a plate piece that hangs downward from the vicinity of the indoor-side end of the mounting piece 36a. The protruding piece 36b is arranged with a gap G1 having a predetermined width in the prospective direction between it and the finding surface 70a. The gap G1 becomes a groove portion (first groove portion) 78 into which the upper frame 64a (corner tube portion 68) of the screen door 15 is inserted and supported. The head of the screw 76 is arranged at the bottom (ceiling surface) of the groove portion 78 and is hidden from the indoor side. The cover piece 36c is a plate piece that protrudes upward from the vicinity of the indoor-side end of the mounting piece 36a. The upper end of the cover piece 36c is arranged to abut or be close to the lower surface of the fin portion 71. Thereby, the cover piece 36c can cover the connecting fitting 72 and the screws 75, 76 from the indoor side.

[0042] As shown in FIG. 5, the resin lower frame 19b has a wall portion 80 inside the frame of the hollow portion 35, and a shallow recess 80b is formed on its prospective surface 80a. The indoor-side end of the wall portion 80 protrudes indoors beyond the hollow portion 35. The portion of the wall portion 80 that protrudes indoors can also be used as a portion fixed to the building body with screws.

[0043] The lower attachment member 37 is fixed to the wall portion 80. The lower attachment member 37 has a mounting piece 37a and a pair of protruding pieces 37b, 37c in the prospective direction. The lower attachment member 37 is an extruded profile of a metal material such as an aluminum alloy, for example.

[0044] The mounting piece 37a is arranged along the indoor-outdoor direction and abuts against the expected surface 80a of the wall portion 80. The outdoor-side end of the mounting piece 37a is fixed to the wall portion 80 with a screw 82 using the back plate 81 in the hollow portion 35. The back plate 81 is arranged on the back side of the recess 80b and is fixed to the wall portion 80 with a screw 83. The screw 83 is provided at a position displaced from the screw 82 in the longitudinal direction of the lower attachment member 37 and does not interfere with the screw 82. The recess 80b is a depression for accommodating the head of the screw 83. A plurality of protrusions 37d are formed on the lower surface of the mounting piece 37c. The protrusions 37d are projected against the bottom surface of the recess 80b so as to straddle the head of the screw 83. Thereby, the mounting piece 37c is surely fixed to the expected surface 80a without interfering with the head of the screw 83.

[0045] The protruding pieces 37b and 37c project upward from the mounting piece 37a and are arranged side by side in the indoor-outdoor direction, forming a groove portion (second groove portion) 84 therebetween. The groove portion 84 is a portion where the lower frame 64b (corner tube portion 68) of the screen door 15 is inserted and supported. Although details will be described later, the upper and lower edge portions of the screen door 15 are inserted into the groove portions 78 and 84 in the Kendon method from the indoor side. Therefore, the protruding height of the indoor-side protruding piece 37c is suppressed to be lower than that of the outdoor-side protruding piece 37b, enabling smoother insertion of the lower frame 64b into the groove portion 84. The protruding heights of the protruding pieces 37b and 37c may be the same. The indoor-side protruding piece 37c has a stopper member 85 fixed thereto with a screw 86 at the center in its longitudinal direction (see also FIG. 3). The stopper member 85 is a member for restricting the upward movement of the screen door 15, and details will be described later.

[0046] As shown in FIG. 6, the resin vertical frames 19c and 19d have an indoor-side wall portion 88 of the hollow portion 45 and a fin portion 89 protruding indoors from the outer end of the frame of the finding surface 88a on the indoor side of the wall portion 88. The fin portion 89 can also be used as a portion fixed to the building body with screws. The finding surface 88a of the wall portion 88 and the expected surface 89a inside the frame of the fin portion 89 form a corner portion 90 which is a wall surface bent in an L shape perpendicular to each other. The corner portions 90 and 90 of the left and right resin vertical frames 19c and 19d are arranged to face each other, and the upper and lower attachment members 36 and 37 and the screen door 15 are arranged therebetween.

[0047] Next, the support structure of the screen door 15 and the function and effect of the fitting 10 will be described.

[0048] As shown in FIGS. 2 to 6, for the screen door 15, the corner tube portion 68 of the upper frame 64a is inserted into the groove portion 78 of the upper attachment member 36, and the corner tube portion 68 of the lower frame 64b is inserted into the groove portion 84 of the lower attachment member 37. At this time, the entire lengths of the frames 64a and 64b in the longitudinal direction are inserted into the groove portions 78 and 84. For this reason, the screen door 15 is stably supported by the frame body 12 without rattling and is prevented from coming off. As a result, the fitting 10 can suppress the rattling and the detachment from the frame body 12 even when the screen door 15 is affected by strong wind or the like when, for example, the shoji 14 is opened.

[0049] The screen door 15 can be assembled to the frame body 12 by the kendon method in which the upper edge portion is inserted into the inner part of the groove portion 78 and then the lower edge portion is inserted into the groove portion 84. That is, the screen door 15 is only supported by the frame body 12 by the kendon method, and the entire lengths of the upper and lower edge portions are held in the groove portions 78 and 84 and are prevented from coming off. For this reason, the fitting 10 also facilitates the assembly work of the screen door 15, and the workability is high. The reference numeral 92 in FIG. 5 is a setting block that is placed on the bottom of the groove portion 84 and supports the prospective surface outside the frame of the lower frame 64b of the screen door 15.

[0050] The resin vertical frames 19c and 19d are provided with corner portions 90 that support the vertical frames 64c and 64d of the screen door 15. For this reason, the screen door 15 can be smoothly moved up and down while easily positioning the vertical frames 64c and 64d with the resin vertical frames 19c and 19d during kendon. After the screen door 15 is installed, since the vertical frames 64c and 64d are supported by the resin vertical frames 19c and 19d, the stability of the screen door 15 is further improved.

[0051] In the fitting 10, the screen door 15 is supported by attachment members 36 and 37 attached to the resin upper frame 19a and the resin lower frame 19b. For example, it is also assumed that the fitting 10 has product lineups with and without the screen door 15 respectively. At this time, in the specification without the screen door, the groove portions 78 and 84 (attachment members 36 and 37) can be easily omitted, improving the design and reducing the component cost, and also improving the versatility of the fitting 10.

[0052] The frame body 12 of the present embodiment has a metal frame member 18 provided with door contact pieces 26, 34, and 44 of the shoji 14, and a resin frame member 19 provided on the indoor side of the metal frame member 18. The attachment members 36 and 37 are attached to the resin frame member 19. The groove portion 78 that supports the upper edge portion of the screen door 15 is formed by the upper attachment member 36 and the resin upper frame 19a, and the groove portion 84 that supports the lower edge portion of the screen door 15 is formed in the lower attachment member 37. Thereby, the fitting 10 can enhance the heat insulation performance by the resin frame member 19. Moreover, by making the attachment members 36 and 37, for example, made of metal, the support strength of the screen door 15 is improved compared with the case where the groove portions 78 and 84 are formed only by the resin frame member 19. Since the resin frame member 19 is interposed between the metal frame member 18 and the attachment members 36 and 37, the heat insulation performance of the frame body 12 is not deteriorated by the attachment members 36 and 37.

[0053] Here, the upper attachment member 36 is configured to form a groove portion 78 between the finding surface 70a of the resin upper frame 19a. As a result, the upper attachment member 36 can suppress the protruding piece 36b forming the groove portion 78 from protruding greatly into the opening 16 of the frame body 12. As a result, the screen door 15 can expand its vertical height to the maximum. On the other hand, the lower attachment member 37 is configured to form a groove portion 84 between its protruding pieces 37b and 37c. As a result, even though the building fixture 10 is configured such that the building body is disposed directly below the indoor-side end portion of the wall portion 80 of the resin lower frame 19b, it is possible to form the groove portion 84 on its expected surface 80a. The upper attachment member 36 may have a pair of protruding pieces in the same manner as the lower attachment member 37, and may be configured to form a groove portion for inserting the upper frame 64a therebetween. Conversely, the lower attachment member 37 may have a single protruding piece in the same manner as the upper attachment member 36, and may be configured to form a groove portion between this protruding piece and the finding surface of the resin lower frame 19b.

[0054] Incidentally, since the screen door 15 is supported by the frame body 12 in the Kendon method, the screen door 15 can move upward in a state where only the upper and lower edge portions are inserted into the groove portions 78 and 84. For this reason, when the screen door 15 is subjected to, for example, a gust of wind or a storm, it may be lifted upward, and there is a possibility that the lower edge portion may fall off from the groove portion 84. Therefore, the building fixture 10 of the present embodiment can also include a stopper member 85 that is fixed to the lower frame 12b and locks the lower frame 64b of the screen door 15 to restrict the upward movement of the screen door 15.

[0055] As shown in FIGS. 3 and 5, the stopper member 85 is a sheet metal part formed by bending a metal plate such as stainless steel, steel, or aluminum into an L shape. The stopper member 85 is fixed to the center or near the center in the longitudinal direction of the lower attachment member 37. The stopper member 85 may be provided near both ends in the longitudinal direction of the lower attachment member 37, and its arrangement can be changed as appropriate.

[0056] The stopper member 85 has a fixing portion 85a extending along the vertical direction and a locking portion 85b bent outward from the upper end of the fixing portion 85a to the outdoor side. The fixing portion 85a is fixed to the finding surface on the indoor side of the protruding piece 37c on the indoor side of the lower attachment member 37 with a screw 86. The locking portion 85b is arranged so as to press the prospective surface on the outer side (upper side) of the frame of the square tube portion 68 of the lower frame 64b. Thereby, the stopper member 85 can prevent the sliding door 15 from moving upward, and the sliding door 15 is less likely to come off from the groove portion 84.

[0057] Next, the fitting 10A according to the modified example will be described with reference to FIGS. 7 and 8. In FIGS. 7 and 8, the same reference numerals as those shown in FIGS. 1 to 6 denote the same or similar configurations, and thus detailed descriptions thereof will be omitted as having the same or similar functions and effects.

[0058] In the above, the fitting 10 which is a single-window smoke exhaust window has been exemplified (see FIG. 1). The fitting 10A shown in FIGS. 7 and 8 is a stepped window. The fitting 10A has a protruding window similar to the fitting 10 described above as an upper window 96, and a lower window 97 of a FIX window is provided below the upper window 96.

[0059] The upper window 96 uses a jointless portion 98 different in configuration from the lower frame 12b of the fitting 10 described above as the lower frame of the frame body 12. The jointless portion 98 is a frame member that also functions as the upper frame of the lower window 97. The jointless portion 98 has a metal frame member 98a. The metal frame member 98a is provided with a resin lower frame 19b on the upper indoor side thereof, and a resin frame member 98b of the lower window 97 is provided on the lower indoor side thereof.

[0060] The lower window 97 is, for example, a structure in which the face material 100 of a multilayer glass is supported by a rectangular opening frame 99. The lower window 97 may be a shoji screen having the face material 100 supported by a frame body, and an opening and closing window in which this shoji screen is supported by the opening frame 99 so as to be openable and closable. The upper frame of the opening frame 99 is a blind 98, which is composed of a metal frame material 98a and a resin frame material 98b. The lower frame 99b of the opening frame 99 has a structure in which a resin lower frame 102b is provided on the indoor side of a metal lower frame 102a. The left and right vertical frames 99c, 99d of the opening frame 99 are, for example, provided with a pressing edge similar to the pressing edge 48 on the indoor side of a metal profile in the same manner as the vertical frames 47c, 47d of the above-described shoji screen 14, and the face material 100 is pressed by this pressing edge.

[0061] Therefore, also in such a fitting 10A, since the entire lengths of the upper and lower edge portions of the screen door 15 are supported by the groove portions 78, 84, rattling and dropping of the screen door 15 can be suppressed.

[0062] As described above, the fitting according to one aspect of the present invention is a fitting including a frame body and a screen door fixed to the frame body, wherein the frame body has an upper frame having a first groove portion opening downward and a lower frame having a second groove portion opening upward, and the screen door has the entire length in the longitudinal direction of the upper edge portion inserted into the first groove portion and the entire length in the longitudinal direction of the lower edge portion inserted into the second groove portion. According to such a configuration, since the upper and lower edge portions of the screen door fixed to the frame body are inserted into and supported by the respective groove portions in their entire lengths, the screen door can be stably supported with respect to the frame body without rattling.

[0063] It is provided with a shoji door that is rotatably supported with respect to the frame body on the outdoor side of the screen door. The upper frame has an upper frame body that supports the shoji door and an upper attachment member attached to the indoor side of the upper frame body. The lower frame has a lower frame body that supports the shoji door and a lower attachment member attached to the indoor side of the lower frame body. The first groove portion may be formed between the upper attachment member and the upper frame body or formed in the upper attachment member. The second groove portion may be formed between the lower attachment member and the lower frame body or formed in the lower attachment member. In this way, in a fitting having the same frame body, when the specification does not require a screen door, the upper and lower attachment members can be omitted, improving the design and versatility of the fitting and reducing the component cost.

[0064] It is provided with a connecting fitting fixed to the finding surface on the indoor side of the upper frame body. The upper attachment member has an attachment piece fixed to the connecting fitting and a protruding piece that hangs down from the attachment piece and is installed with a predetermined gap from the finding surface on the indoor side of the upper frame body. The first groove portion may be formed by the gap. In this way, the protruding piece of the upper attachment member that forms the first groove portion is suppressed from protruding greatly into the opening of the frame body, and the vertical height of the screen door can be maximally expanded.

[0065] It is provided with a screw for fixing the attachment piece to the connecting fitting, and the head of the screw may be arranged at the bottom of the first groove portion. In this way, the screw for fixing the upper attachment member to the connecting fitting is not exposed on the appearance of the fitting, improving the design.

[0066] The lower attachment member may have an attachment piece fixed to the prospective surface of the lower frame body and a pair of protruding pieces that protrude upward from the attachment piece and have the second groove portion formed therebetween. In this way, even in a configuration where a building structure is arranged directly below the lower frame body, the second groove portion can be easily formed.

[0067] The upper frame body includes a metal upper frame provided with a door stop for receiving the shoji in the fully closed position, and a resin upper frame provided on the indoor side of the metal upper frame. The lower frame body includes a metal lower frame provided with a door stop for receiving the shoji in the fully closed position, and a resin lower frame provided on the indoor side of the metal lower frame. The upper attachment member may be made of metal and attached to the resin upper frame, and the lower attachment member may be made of metal and attached to the resin lower frame. In this way, while ensuring the heat insulation performance of the fixture, the screen door can be supported with high strength.

[0068] The screen door includes a screen door frame having an upper frame forming the upper edge portion, a lower frame forming the lower edge portion, and a pair of vertical frames, and a net body stretched over the screen door frame. It may be configured to include a stopper member that is fixed to the lower frame and locks the lower frame to restrict upward movement of the screen door. In this way, when the screen door is subjected to a gust of wind or the like, it is possible to further suppress the upward movement of the screen door and the detachment of its lower edge portion from the second groove portion.

[0069] Note that the present invention is not limited to the above-described embodiments, and it goes without saying that it can be freely changed without departing from the gist of the present invention.
