Description

[Technical Field]

[0001] The present invention relates to building materials, and more particularly to building materials in which a shoji screen is formed by interconnecting frame materials having a metal frame portion formed from metal and a resin frame portion formed from resin. [Background technology]

[0002] As the frame material for a shoji screen, a fitting has been proposed that uses a composite frame with a metal frame section formed from a metal such as an aluminum alloy and a resin frame section formed from a resin. The metal frame section and the resin frame section have a frame base section that is positioned on the outer periphery of the face material and a fin section that extends from the frame base section in the viewing direction, and the face material is accommodated between the fin sections. This type of fitting has the advantage of combining the improved weather resistance and mechanical strength provided by the metal frame section with the high thermal insulation provided by the resin frame section (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-317810 Summary of the Invention [Problem to be solved by the invention]

[0004] To connect the frames together to form a shoji screen, the metal frame base of one frame needs to be connected to the metal frame base of the other frame, which requires processing such as cutting out the fins from each frame, which can complicate the assembly process.

[0005] In view of the above circumstances, the present invention aims to provide a fitting that can simplify the assembly work of shoji screens. [Means for solving the problem]

[0006] In order to achieve the above object, the fitting according to the present invention is a fitting comprising a shoji screen in which a frame material provided around a surface material comprises a metal frame portion formed from metal and a resin frame portion formed from resin, the metal frame portion having a metal frame base portion disposed on the outer periphery of the surface material and a metal fin portion extending from the metal frame base portion in the find direction, the resin frame portion having a resin frame base portion disposed on the outer periphery of the surface material and a resin fin portion extending from the resin frame base portion in the find direction, and the edge of the surface material is housed between the metal fin portion and the resin fin portion, The first and second frames, the ends of which are connected to each other, are characterized in that the metal frame bases are connected to each other in a state in which the end face of the metal fin portion of the first frame abuts against the extended edge portion of the metal fin portion of the second frame and the end face of the metal frame base of the first frame abuts against the expected inner surface of the metal frame base of the second frame, the end face of the resin fin portion of the first frame abuts against the extended edge portion of the resin fin portion of the second frame, and an end member is provided at the end of the second frame in a state in which it covers the portion of the metal frame portion of the first frame that is contained in the second frame. [Effects of the Invention]

[0007] According to the present invention, the end face of the metal fin portion of the first frame member abuts against the extended edge of the metal fin portion of the second frame member, and the end face of the resin fin portion of the first frame member abuts against the extended edge of the resin fin portion of the second frame member, so there is no need to cut out the metal fin portion and the resin fin portion of the second frame member. This means that the first frame member and the second frame member can be connected by processing only the first frame member, making it easier to assemble the shoji screen.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Preferred embodiments of the fittings according to the present invention will be described in detail below with reference to the accompanying drawings. Note that, for convenience, the terms "invisible direction" and "visible direction" will be used below. The "invisible direction" is the direction along the depth of the fittings, as indicated by arrow A in the drawings. A surface along the invisible direction will be referred to as a "visible face." The "visible direction" is the direction perpendicular to the invisible direction in the case of an object that extends horizontally, such as a sill. In the case of an object that extends vertically, such as a vertical frame, the "visible direction" is the horizontal direction perpendicular to the invisible direction. A surface along the invisible direction will be referred to as a "visible face."

[0010] 1 to 4 show a fitting according to an embodiment of the present invention. The fitting illustrated here is used as a back door and includes an opening frame 1 and a door panel 2. The opening frame 1 is configured by assembling an upper opening frame 1A, a lower opening frame 1B, and left and right vertical opening frames 1C around all four sides. The door panel 2 is configured by a door frame body (frame body) 10 and two ventilation shoji screens 20A and 20B, and is supported so as to be openable and closable relative to the opening frame 1 by interposing a hinge 3 between the door frame body 10 and one of the vertical opening frames 1C. The opening frame 1 is made up of an upper opening frame 1A, a lower opening frame 1B, and left and right vertical opening frames 1C. The opening frame 1 is a composite type including a metal opening frame portion 1m molded from a metal such as an aluminum alloy and a resin opening frame portion 1p molded from a resin, and is attached to the building frame with the metal opening frame portion 1m facing outward. The metal opening frame 1m and the resin opening frame 1p are extruded members, and are configured so that the portions along the entire longitudinal length thereof have a substantially uniform cross-sectional shape.

[0011] The door frame 10 is constructed by assembling an upper door frame 11, a lower door frame 12, and left and right vertical door frames 13, 14 all around. The upper door frame 11, lower door frame 12, and vertical door frames 13, 14 are all composite types equipped with a metal frame portion formed from a metal such as an aluminum alloy and a resin frame portion formed from a resin, and are supported by the opening frame 1 with the metal frame portion facing the exterior. The metal frame portion and the resin frame portion are both extruded shapes, and each is constructed so that the entire longitudinal length has a substantially uniform cross-sectional shape.

[0012] The metal frame portion 11A of the upper door frame 11 is formed by integrally molding the upper door frame base 11A1 and the upper door support wall portion 11A2. The upper door frame base 11A1 is hollow and has a vertically elongated, approximately rectangular cross section. A resin frame portion 11B is attached to this upper door frame base 11A1 so as to cover almost the entire surface facing the interior of the vehicle. Furthermore, a resin-molded upper frame recess member 11C is provided on the inner peripheral surface of the upper door frame base 11A1 and the resin frame portion 11B so as to protrude toward the interior of the vehicle. The upper door support wall portion 11A2 is a thin plate-like member that extends almost horizontally from the inner peripheral portion of the upper door frame base 11A1 on the surface facing the exterior of the vehicle toward the outside, and then bends almost at a right angle toward the inner peripheral side.

[0013] The metal frame portion 12A of the lower door frame 12 is integrally formed with the lower door frame base 12A1, the lower door boundary wall portion 12A2, the lower door inner peripheral wall portion 12A3, and the lower door support wall portion 12A4. Like the upper door frame base 11A1, the lower door frame base 12A1 is hollow and has a vertically elongated, approximately rectangular cross section. The dimensions of the lower door frame base 12A1 along the front and rear directions are approximately the same as those of the upper door frame base 11A1. A resin frame portion 12B is attached to the lower door frame base 12A1 so as to cover almost the entire front surface facing the interior of the vehicle. The lower door boundary wall portion 12A2 is a thin plate-like member that protrudes inward from approximately the center of the front surface of the lower door frame base 12A1, which is the inner peripheral side of the front surface. The lower door inner peripheral wall portion 12A3 protrudes inward from a corner on the interior side of the lower door frame base 12A1, then bends toward the interior, and bends again toward the interior. A resin-molded lower frame cover member 12C is attached to the outer surface of the lower door inner peripheral wall portion 12A3. The lower door support wall portion 12A4 is a thin plate-like member that extends gradually downward from an exterior corner on the inner peripheral side of the lower door frame base 12A1 toward the exterior. The protruding distance of the lower door support wall portion 12A4 toward the exterior is approximately the same as the protruding distance of the upper door support wall portion 11A2 toward the exterior.

[0014] The metal frame portion 13A of the vertical door frame 13, which forms the hanging origin, has a hanging origin outer peripheral portion 13A1 and a hanging origin inner peripheral portion 13A2, which are molded separately from each other. The hanging origin outer peripheral portion 13A1 is hollow with a horizontally elongated, approximately rectangular cross section. A resin frame portion 13B is attached to this hanging origin outer peripheral portion 13A1 so as to cover almost the entire visible surface facing the interior of the room. The hanging origin inner peripheral portion 13A2 is integrally molded with a vertical door recess wall portion 13A2a, a vertical door inner recess wall portion 13A2b, a vertical door outer recess wall portion 13A2c, and a vertical door boundary wall portion 13A2d. The vertical door recess wall portion 13A2a is a flat plate extending approximately vertically along the recess direction. The vertical door inner sight wall 13A2b is a thin plate extending from the interior edge of the vertical door projection wall 13A2a toward the inner periphery. The vertical door outer sight wall 13A2c is a flat plate extending from the exterior edge of the vertical door projection wall 13A2a toward the inner periphery. The vertical door boundary wall 13A2d is a thin plate protruding toward the inner periphery at a portion of the projection surface on the inner periphery of the vertical door projection wall 13A2a that is approximately equidistant from the vertical door inner sight wall 13A2b and the vertical door outer sight wall 13A2c. A vertical frame inner periphery cover member 13C molded from resin is attached to the portion extending from the projection surface of the vertical door boundary wall 13A2d facing the interior of the room to the projection surface on the inner periphery of the vertical door projection wall 13A2a. In addition, a vertical frame outer periphery cover member 13D molded from resin is attached to the portion extending from the sight surface of the vertical door inner sight wall portion 13A2b facing the interior of the room to the sight surface on the outer periphery side of the vertical door sight wall portion 13A2a.

[0015] The metal frame portion 14A of the vertical door frame 14 on the door front side has a door front outer peripheral portion 14A1 and a door front inner peripheral portion 14A2, which are molded separately from each other. The door front outer peripheral portion 14A1 is hollow with a horizontally elongated, approximately rectangular cross section and differs from the hanging base outer peripheral portion 13A1 in that it has a cover fin portion 14A1a. That is, the door front outer peripheral portion 14A1 has an integral cover fin portion 14A1a that protrudes from the exterior corner of the outer periphery toward the outside and then bends toward the outer periphery. A resin frame portion 14B is attached to this door front outer peripheral portion 14A1 so as to cover almost the entire visible surface facing the interior of the room. The door-end inner peripheral portion 14A2, like the hanging-end inner peripheral portion 13A2, is formed by integrally molding a vertical door frame base 14A2a, a vertical door inner sight wall portion 14A2b, a vertical door outer sight wall portion 14A2c, and a vertical door boundary wall portion 14A2d. It is also similar to the hanging-end vertical door frame 13 in that it is provided with a vertical frame inner peripheral cover member 14C and a vertical frame outer peripheral cover member 14D. Reference numeral 15 in the drawing denotes a door handle provided on the vertical door frame 14 on the door-end side.

[0016] The two ventilation shoji screens 20A, 20B are arranged so as to be movable up and down, respectively, in a portion inside the room relative to boundary wall portions 12A2, 13A2d, 14A2d and a portion outside the room relative to boundary wall portions 12A2, 13A2d, 14A2d inside the door frame 10. The indoor ventilation shoji screen (hereinafter referred to as inner shoji screen 20A when distinguishing between them) is constructed by attaching an upper frame (first frame member) 22A, a lower frame (first frame member) 23A, and left and right vertical frames (second frame members) 24A to the four periphery of a rectangular double-glazed glass (face material) 21A. The ventilation shoji screen on the outside of the room (hereinafter referred to as the outer shoji screen 20B when distinguishing between them) is constructed by attaching an upper frame (first frame material) 22B, a lower frame (first frame material) 23B, and left and right vertical frames (second frame materials) 24B to the four periphery of a rectangular double-glazed glass (face material) 21B. In this embodiment, the inner shoji screen 20A is positioned below with the upper frame 22A of the inner shoji screen 20A and the lower frame 23B of the outer shoji screen 20B arranged side by side in the forward direction, and the dimensions of each ventilation shoji screen 20A, 20B are set so that when the outer shoji screen 20B is positioned above, it can block the opening of the door frame body 10.

[0017] Furthermore, the inner shoji screen 20A has dimensions set along the left and right so that the facing surfaces of the left and right vertical stiles 24A facing the room are simultaneously covered by the vertical door inner facing walls 13A2b, 14A2b, respectively, while a gap is secured between the vertical door facing walls 13A2a, 14A2a of the vertical door frames 13, 14 and the facing surfaces of the vertical stiles 24A, allowing for fitting by fitting the vertical door in. In other words, for example, when one vertical stile 24A of the inner shoji screen 20A is moved closer to the vertical door frame 13, the other vertical stile 24A can be positioned in a state where it is completely exposed to the outside from the vertical door inner facing wall 14A2b of the vertical door frame 14. Similarly, the outer shoji screen 20B has dimensions set along the left and right so that the visible surfaces of the left and right vertical stiles 24B facing the outside are simultaneously covered by the vertical door outer visible walls 13A2c, 14A2c, respectively, while a gap is secured between the vertical door visible walls 13A2a, 14A2a of the vertical door frames 13, 14 and the visible surfaces of the vertical stiles 24B so that they can be fitted in by fitting them in on the left and right. Therefore, for example, when one vertical stile 24B of the outer shoji screen 20B is moved closer to the vertical door frame 13, the other vertical stile 24B can be positioned so that it is completely exposed to the outside from the vertical door outer visible wall 14A2c of the vertical door frame 14.

[0018] Although not shown in the figure, the inner shoji 20A and the outer shoji 20B are connected to each other by a wire 30. The middle part of the wire 30 is wound around a pulley 31 provided on the vertical door frames 13, 14, and one end hanging down from the pulley 31 is connected to the inner shoji 20A, and the other end is connected to the outer shoji 20B. As described above, the inner shoji 20A and the outer shoji 20B are connected by the wire 30, and operate so that, for example, when the inner shoji 20A is moved upward, the outer shoji 20B moves downward.

[0019] As shown in Figures 5 to 7, the upper frame 22A, lower frame 23A, and left and right vertical frames 24A of the inner shoji screen 20A and the upper frame 22B and left and right vertical frames 24B of the outer shoji screen 20B are all composite structures with metal frame sections molded from a metal such as an aluminum alloy and resin frame sections molded from a resin, with the metal frame sections facing the outside of the room and holding the double-glazed glass 21A, 21B between them. The lower frame 23B of the outer shoji screen 20B has no portion facing the interior of the room and is therefore integrally molded from a metal such as an aluminum alloy. The frames that make up these ventilation shoji screens 20A, 20B are all extruded shapes, with either metal or resin sections, and each has a substantially uniform cross-sectional shape along its entire length. In addition, the symbol 40 in the figure indicates a lattice screen door constructed by providing a net 42 and horizontal bars 43 inside a screen door frame 41, and is attached to the surface of the door panel 2 facing outside so as to cover the opening of the door frame 10.

[0020] Below, we will explain in detail the configuration and connection state of the upper frame 22A, lower frame 23A, left and right vertical frames 24A of the inner shoji 20A, and the upper frame 22B, left and right vertical frames 24B of the outer shoji 20B, which are composite types, and also explain the characteristic parts of the present invention.In the embodiment, since the lower frame 23A of the inner shoji 20A and the upper frame 22B of the outer shoji 20B are approximately symmetrical to each other, only the upper frame 22B of the outer shoji 20B will be explained as a representative, and the lower frame 23A of the inner shoji 20A will be assigned the same symbol and will not be explained again. Furthermore, the left and right vertical frames 24A of the inner shoji 20A are approximately symmetrical to each other, and the left and right vertical frames 24B of the outer shoji 20B are approximately symmetrical to each other, and the vertical frame 24A on the hanging side of the inner shoji 20A and the vertical frame 24B on the hanging side of the outer shoji 20B are approximately identical to each other. Therefore, only the vertical frame 24B on the hanging side of the outer shoji 20B will be described as a representative, and the left and right vertical frames 24A of the inner shoji 20A and the vertical frame 24B on the door edge side of the outer shoji 20B will be given the same reference numerals and will not be described again.

[0021] As shown in Figure 5, the metal frame portion 51 constituting the upper frame 22B of the outer sash 20B is formed by integrally molding an outer metal frame base portion 51a and an outer metal fin portion 51b. The outer metal frame base portion 51a is positioned so as to cover the end face of the double-glazed glass 21B in a portion that is closer to the outer periphery than the end face of the double-glazed glass 21B. In the illustrated example, the outer metal frame base portion 51a is composed of an outer metal frame base portion 51a1, an outer metal engagement plate portion 51a2, an outer bent plate portion 51a3, an outer metal recessed wall portion 51a4, an outer metal recessed wall portion 51a5, and a metal edge protrusion wall portion (edge ​​protrusion portion) 51a6. The outer metal frame base portion 51a1 is a plate-like portion extending approximately horizontally along the recessed direction. A protruding screw hole 51a7 is provided at approximately the center of the inner peripheral portion of the outer metal frame base plate portion 51a1. The outer metal engagement plate portion 51a2 extends in the forward direction from the interior-side edge of the outer metal frame base plate portion 51a1. The outer bent plate portion 51a3 protrudes from the exterior-side edge of the outer metal frame base plate portion 51a1 toward the outer periphery, then bends approximately horizontally toward the outside, and then bends again toward the outer periphery. The outer metal projection wall portion 51a4 extends in the forward direction from the outer peripheral edge of the outer bent plate portion 51a3. The interior-side edge of the outer metal projection wall portion 51a4 protrudes toward the room beyond the exterior peripheral edge of the outer bent plate portion 51a3, thereby forming an engagement protrusion 51a8. The outer metal sight wall 51a5 extends in the sight direction from the exterior edge of the outer metal sight wall 51a4 toward the inner periphery. The protrusion dimension of the outer metal sight wall 51a5 from the outer metal frame base plate 51a1 is approximately the same as the protrusion dimension of the screw holes 51a7. The interior edge of the outer metal sight wall 51a5 is slightly bent toward the exterior. The metal edge protrusion wall 51a6 protrudes toward the exterior from the exterior edge of the outer metal sight wall 51a4, then bends slightly toward the exterior, and continues extending in the sight direction toward the exterior. The outer metal fin 51b extends in the sight direction from the extending edge of the bent portion of the outer metal sight wall 51a5 toward the inner periphery.More specifically, the outer metal fin portion 51b extends from a position outside the chamber by the plate thickness of the outer metal sight wall portion 51a5 toward the inner periphery.

[0022] The resin frame portion 52 constituting the upper frame 22B of the outer shoji screen 20B is formed by integrally molding an outer resin frame base portion 52a and an outer resin fin portion 52b. The outer resin frame base portion 52a is arranged to cover the end face of the double-glazed glass 21B in a portion that is closer to the outer periphery than the end face of the double-glazed glass 21B. In the illustrated example, the outer resin frame base portion 52a is composed of an outer resin frame substrate portion 52a1, an outer resin sight wall portion 52a2, an outer resin engagement receiving portion 52a3, and a resin edge protrusion wall portion (edge ​​protrusion portion) 52a4. The outer resin frame substrate portion 52a1 is in the form of a plate that extends almost horizontally along the projection direction. The edge portion of the outer resin frame substrate portion 52a1 facing the outside of the room is formed in a stepped shape that is one step closer to the inner periphery. The outer resin sight wall 52a2 extends in the sight direction from the interior edge of the outer resin frame base plate 52a1 toward the inner periphery. The outer resin engagement receiving portion 52a3 protrudes from the extended edge of the outer resin sight wall 52a2 to the exterior and then bends toward the outer periphery. The resin edge protrusion wall 52a4 forms a rectangular cylindrical portion that protrudes outward from the interior edge of the outer surface of the outer resin frame base plate 52a1. The outer resin fin portion 52b extends in the sight direction from the inner periphery of the outer resin sight wall 52a2 toward the inner periphery. More specifically, the outer resin fin portion 52b extends in an extension of the outer resin sight wall 52a2. The extending edge of the outer resin fin portion 52b is slightly bent toward the outer periphery.

[0023] The metal frame portion 51 and the resin frame portion 52 that constitute the upper frame 22B of these outer sashes 20B are interconnected by inserting the outdoor-side edge of the outer resin frame base portion 52a1 between the engaging protrusion portion 51a8 and the outer bent plate portion 51a3 of the outer metal frame base portion 51a, and engaging the outer metal engaging plate portion 51a2 between the outer resin sight wall portion 52a2 and the outer resin engaging receiving portion 52a3 of the outer resin frame base portion 52a. When the metal frame portion 51 and the resin frame portion 52 are connected to each other, the outer peripheral surface of the outer metal recessed wall portion 51a4 and the outer peripheral surface of the outer resin frame base portion 52a1 are positioned on approximately the same plane, and the distance from this plane to the inner peripheral edge of the outer metal recessed wall portion 51a5 and the distance from this plane to the inner peripheral edge of the outer resin recessed wall portion 52a2 are approximately the same. On the outer peripheral surface formed by the outer peripheral surface of the outer metal recessed wall portion 51a4 and the outer peripheral surface of the outer resin frame base portion 52a1, a gutter portion 53 is formed between the resin edge protruding wall portion 52a4 and the metal edge protruding wall portion 51a6, which protrude from both side edges. Furthermore, the outer metal fin portion 51b and the outer resin fin portion 52b face each other and protrude approximately the same distance from the outer metal recessed wall portion 51a4. The dimensions between the outer metal fin portion 51b and the outer resin fin portion 52b are set so that the edge of the double glazing glass 21B can be sandwiched between them via the glazing channel 54.

[0024] As shown in FIG. 6, the metal frame portion 61 constituting the upper frame 22A of the inner shoji screen 20A is formed by integrally molding an inner metal frame base portion 61a and an inner metal fin portion 61b. The inner metal frame base portion 61a is positioned so as to cover the edge of the double-glazed glass 21B in a portion that is closer to the outer periphery than the edge of the double-glazed glass 21B. In the illustrated example, the inner metal frame base portion 61a is composed of an inner metal frame substrate portion 61a1, an inner metal sight wall portion 61a2, an inner metal engagement plate portion 61a3, and a metal outer periphery cover portion 61a4. The inner metal frame substrate portion 61a1 is a plate-like portion that extends approximately horizontally along the projection direction. A screw hole 61a5 is provided so as to protrude from the inner periphery of the inner metal frame substrate portion 61a1. The inner metal sight wall 61a2 extends in the sight direction from the exterior edge of the inner metal frame base plate 61a1. The outer periphery of the inner metal sight wall 61a2 is provided with an engagement piece 61a6 that bends toward the exterior at a nearly right angle. The portion of the inner metal sight wall 61a2 that extends inward from the inner metal frame base plate 61a1 extends to a position nearly equal to the protrusion dimension of the screw hole 61a5, and the extending edge bends slightly toward the exterior. The inner metal engagement plate 61a3 extends from the outer surface of the interior edge of the inner metal frame base plate 61a1 toward the exterior, then bends toward the interior, and then bends again toward the interior. An engagement groove 61a7 opens toward the interior between the extending edge of the inner metal engagement plate 61a3 and the inner metal frame base plate 61a1. The metal outer periphery cover 61a4 connects the inner metal sight wall 61a2 and the inner metal engagement plate 61a3, forming a rectangular cylindrical hollow in the outer periphery of the inner metal frame base plate 61a1. The inner metal fin 61b extends in the sight direction from the extending edge of the inner metal sight wall 61a2, which bends outward. More specifically, the inner metal fin 61b extends inward from a position that is further outward than the inner metal sight wall 61a2 by the plate thickness. Reference numeral 61a8 in the figure denotes a smoke deflector provided on the inner metal sight wall 61a2.

[0025] The resin frame portion 62 constituting the upper frame 22A of the inner shoji screen 20A is formed by integrally molding an inner resin frame base portion 62a and an inner resin fin portion 62b. The inner resin frame base portion 62a is positioned so as to cover the end face of the double-glazed glass 21A in a portion that is closer to the outer periphery than the end face of the double-glazed glass 21A. In the illustrated example, the inner resin frame base portion 62a is composed of an inner resin frame substrate portion 62a1, an inner resin sight hollow portion 62a2, and an inner resin engagement claw portion 62a3. The inner resin frame substrate portion 62a1 is a plate-like member extending approximately horizontally along the projection direction, and is sized to cover the entire projection surface on the outer periphery above the inner shoji screen 20A and to protrude into the room. The exterior edge of the inner resin frame base plate 62a1 bends inward and then bends indoors, forming an insertion groove 62a4 into which the engagement piece 61a6 of the metal frame 61 can be inserted. The inner resin sight hollow 62a2 is a rectangular cylindrical protrusion that protrudes inward from the interior surface of the inner resin frame base plate 62a1. The inner resin engagement claw 62a3 protrudes outward from the exterior surface of the inner resin sight hollow 62a2 and then bends outward. The inner resin fin 62b extends in the sight direction from the interior edge of the protruding end surface of the inner resin sight hollow 62a2 toward the interior. The extending edge of the inner resin fin 62b is slightly bent outward.

[0026] The metal frame portion 61 and the resin frame portion 62 that make up the upper frame 22A of the inner shoji screen 20A are interconnected by inserting the engagement piece 61a6 into the insertion groove 62a4 and engaging the inner resin engagement claw 62a3 in the engagement receiving groove 61a7. When the metal frame portion 61 and the resin frame portion 62 are interconnected, the protruding end face of the inner resin sight hollow portion 62a2 is located slightly outside the inner edge of the inner metal sight wall portion 61a2. The inner metal fin portion 61b and the inner resin fin portion 62b face each other and protrude approximately the same distance from the inner resin frame base portion 62a1. The inner metal fin portion 61b and the inner resin fin portion 62b are spaced apart to sandwich the edge of the double-glazed glass 21A via the glazing channel 54. The mutual distance between the inner metal fin portion 61b and the inner resin fin portion 62b is approximately the same as the mutual distance between the outer metal fin portion 51b and the outer resin fin portion 52b provided on the upper frame 22B of the outer screen 20B.

[0027] As shown in Figure 7, the metal frame portion 71 constituting the vertical frame 24B on the hanging side of the outer screen 20B is integrally formed with a vertical frame base portion 71a and a vertical frame fin portion 71b. The vertical frame base portion 71a is positioned to cover the edge of the double-glazed glass 21B in a portion closer to the periphery than the edge of the double-glazed glass 21B. In the illustrated example, the vertical frame base portion 71a is composed of a vertical frame base portion 71a1, a vertical frame wall portion 71a2, and a vertical engagement wall portion 71a3. The vertical frame base portion 71a1 is a plate-like portion extending approximately horizontally along the projection direction. The vertical frame wall portion 71a2 extends in the projection direction from the outside edge of the vertical frame base portion 71a1 toward the periphery. The extending edge of the vertical metal sight wall portion 71a2 is bent toward the interior of the room. The vertical engagement wall portion 71a3 extends from the interior edge of the vertical metal frame base portion 71a1 toward the outer periphery. This vertical engagement wall portion 71a3 is provided with a vertical engagement claw portion 71a4, an engagement protrusion portion 71a5, and a vertical engagement receiving portion 71a6. The vertical engagement claw portion 71a4 protrudes toward the interior from the interior surface of the vertical metal frame base portion 71a1 facing the room, then bends toward the inner periphery and bends again toward the room, opening on the inner periphery. The engagement protrusion portion 71a5 protrudes from the extending edge of the vertical engagement wall portion 71a3 toward the outer periphery. The vertical engagement receiving portion 71a6 bends from the extended edge of the vertical engagement wall portion 71a3 toward the outside of the room, then extends toward the periphery and further bends toward the room, forming a vertical engagement groove 71a7 between them. The outer peripheral edge of the vertical engagement receiving portion 71a6 protrudes to a position approximately equal to the protrusion dimension of the vertical metal sight wall portion 71a2 from the vertical metal frame base portion 71a1. A guide groove 71c is formed between the vertical metal sight wall portion 71a2 and the vertical engagement receiving portion 71a6. The guide groove 71c opens to both the upper and lower end surfaces of the vertical frame 24B and also to the projected surface that is the outer periphery of the vertical frame 24B. As is clear from the figure, the opening width of this guide groove 71c is configured to be smaller than the internal width. The vertical metal fin portion 71b extends in the viewing direction from the edge portion of the vertical metal frame base portion 71a1 that faces the exterior toward the inner periphery.

[0028] The resin frame portion 72 constituting the vertical frame 24B on the hanging side of the outer shoji screen 20B is formed by integrally molding a vertical frame base portion 72a and a vertical frame fin portion 72b. The vertical frame base portion 72a is positioned so as to cover the end face of the double-glazed glass 21B in a portion that is closer to the outer periphery than the end face of the double-glazed glass 21B. In the illustrated example, the vertical frame base portion 72a is composed of a vertical frame base portion 72a1, a vertical frame wall portion 72a2, and a vertical frame engagement receiving portion 72a3. The vertical frame base portion 72a1 is a plate-like portion that extends approximately horizontally along the projection direction. The edge portion of the vertical frame base portion 72a1 facing the outside of the room is formed in a stepped shape that is one step closer to the inner periphery. The vertical resin sight wall portion 72a2 extends in the sight direction from the interior edge of the vertical resin frame base portion 72a1 toward the inner periphery. The vertical resin engagement receiving portion 72a3 protrudes outside the room from the extending edge of the vertical resin sight wall portion 72a2 and then bends toward the outer periphery. The vertical resin fin portion 72b extends in the sight direction from a portion located on the inner periphery of the vertical resin sight wall portion 72a2 toward the inner periphery. More specifically, the vertical resin fin portion 72b extends in the sight direction along the extension of the vertical resin sight wall portion 72a2. A protrusion portion 72c is provided on the extending edge of the vertical resin fin portion 72b. The protrusion portion 72c extends from the exterior-facing surface of the vertical resin fin portion 72b toward the exterior, approximately in the direction of the wall.

[0029] The metal frame portion 71 and the resin frame portion 72 that make up the vertical frame 24B of the outer sash 20B are connected to each other by inserting the exterior edge of the vertical resin frame base portion 72a1 into the vertical engagement groove 71a7 to engage with the engagement protrusion 71a5, and by engaging the vertical engagement claw 71a4 with the vertical resin frame engagement receptacle 72a3. When the metal frame portion 71 and the resin frame portion 72 are connected to each other, the vertical metal frame base portion 71a and the portion of the vertical resin frame engagement receptacle 72a3 that extends in the forward direction are located on approximately the same plane. Furthermore, the vertical metal fin portion 71b and the vertical resin fin portion 72b face each other, and the distance from the vertical metal frame base portion 71a1 to the protrusion 72c is approximately the same as the protrusion dimension of the vertical resin fin portion 72b from the vertical metal frame base portion 71a1. A dimension is ensured between the vertical metal fin portion 71b and the vertical resin fin portion 72b so that the edge of the double-glazed glass 21B can be sandwiched via the glazing channel 54. However, the mutual distance between the vertical metal fin portion 71b and the vertical resin fin portion 72b is set larger than the mutual distance between the outer metal fin portion 51b and the outer resin fin portion 52b. More specifically, when the vertical frame 24B and the upper frame 22B are arranged opposite each other so that the vertical metal fin portion 71b and the outer metal fin portion 51b are positioned on the same plane, the mutual distance between the vertical metal fin portion 71b and the vertical resin fin portion 72b is set so that the extended edge of the outer resin fin portion 52b abuts against the protrusion portion 72c more inward than the vertical resin fin portion 72b.

[0030] 8 to 13 show the connecting portion between the upper frame 22B and the vertical frame 24B in the outer screen 20B. Note that the following description will focus on the portion between one vertical frame 24B, but the same configuration is used for the portion between the other vertical frame 24B. As for the ends of the vertical frame 24B, as shown in Fig. 15, the metal frame portion 71 and the resin frame portion 72 are cut at the same position along the longitudinal direction in a direction perpendicular to each other.

[0031] In contrast, the ends of the upper frame 22B are cut perpendicularly along their longitudinal axis, with the ends of the outer metal frame base 51a projecting from the end faces of the resin frame 52, as shown in FIG. 14. More specifically, the metal frame 51 is configured such that the end faces of the outer metal fins 51b are cut off so that they are shorter than the end faces of the outer metal frame base 51a. The position at which the outer metal fins 51b are cut off is the same as the projection of the vertical metal fins 71b from the vertical resin frame base 72a1 in the metal frame 71 of the vertical frame 24B. The length of the resin frame 52 is set so that the position of the end face is approximately aligned with the position of the end face of the outer metal fins 51b. However, the outer metal engagement plate portion 51a2 engaged between the outer resin sight wall portion 52a2 and the outer resin engagement receiving portion 52a3 of the resin frame portion 52 in the outer metal frame base portion 51a is cut so that the position of the end face is the same as that of the resin frame portion 52.

[0032] When the end of the upper frame 22B, whose end has been processed in advance as described above, is joined to the end of the vertical frame 24B, the outer metal frame base 51a is inserted between the vertical metal fin 71b and the vertical resin fin 72b, and the end face of the outer metal frame base 51a abuts the vertical metal frame base 71a1, as shown in Figures 8 to 13. Therefore, from this state, if a screw is threaded into the screw hole 51a7 of the upper frame 22B through the vertical metal frame base 71a1, the metal frame portion 51 of the upper frame 22B and the metal frame portion 71 of the vertical frame 24B can be connected. At this time, the end face of outer metal fin 51b abuts against the extending edge of vertical metal fin 71b, and the end face of outer resin fin 52b abuts against protrusion 72c inside vertical resin fin 72b, so that no gaps are created between the facing surfaces facing outside and the facing surfaces facing inside. An outer sliding piece 80 is attached to the end of vertical stile 24B to cover it.

[0033] The outer sliding piece 80 is molded from resin and, as shown in Figures 8-10 and 16, covers the end face of the vertical stile 24B and the end face of the resin edge protrusion wall portion 52a4 of the upper stile 22B, which protrudes above the end face of the vertical stile 24B. It is sized to protrude outward from the projection surface on the outer periphery of the vertical stile 24B. The projection dimension of the outer sliding piece 80 from the outer stile 20B is set to fill the gap for a push-in between the vertical door projection walls 13A2a, 14A2a of the vertical door frames 13, 14 and the projection surface of the vertical stile 24B without interfering with the smooth movement of the outer stile 20B. As can be seen from the figures, the outer sliding piece 80 is provided with a drainage recess 81 that connects to the gutter portion 53 formed between the resin edge protrusion wall portion 52a4 and the metal edge protrusion wall portion 51a6 of the upper stile 22B. The drainage recess 81 has an inner bottom surface 82 located inward of the outer peripheral surface formed by the outer peripheral surface of the outer metal recess wall portion 51a4 and the outer peripheral surface of the outer resin frame base portion 52a1. This drainage recess 81 has a drainage hole 83 formed in part of its side and a screw insertion hole 84 formed in its inner bottom surface 82. To attach the outer sliding piece 80 to the outer shoji screen 20B, simply screw the screw through the screw insertion hole 84 in the drainage recess 81 and into the metal frame portion 51 of the upper frame 22B from the outer peripheral side. The drainage recess 81 of the outer sliding piece 80 attached to the outer shoji screen 20B is in communication with the space between the vertical metal fin portion 71b and the vertical resin fin portion 72b of the vertical frame 24B via the drainage hole 83 on the side. As described above, the lower frame 23A of the inner shoji 20A has a structure similar to that of the upper frame 22B of the outer shoji 20B. Therefore, the connecting portion between the lower frame 23A and the vertical frame 24A of the inner shoji 20A is also connected to each other at their ends in a similar structure to that described above.

[0034] Figures 17 to 20 show the connection between the upper frame 22A and the vertical frame 24A in the inner shoji screen 20A. Note that the following description will focus on the connection between one vertical frame 24A, but the connection between the other vertical frame 24A is configured in the same way. As shown in Figure 22, at the end of the vertical frame 24A, the metal frame portion 71 and the resin frame portion 72 are cut at the same position along the longitudinal direction in a direction perpendicular to each other. However, since the inner shoji screen 20A has a smoke deflector portion 61a8 on the upper frame 22A, a notch 71b1 is provided in the vertical metal fin portion 71b at the portion corresponding to the smoke deflector portion 61a8.

[0035] In contrast, as shown in FIG. 21, the ends of the upper frame 22A are cut perpendicularly along their longitudinal axis, with the ends of the inner metal frame base 61a protruding from the end faces of the resin frame 62. More specifically, the metal frame 61 is configured such that the positions of its end faces are shorter than the end faces of the inner metal frame base 61a by cutting off the ends of the inner metal fin 61b and the smoke deflector 61a8. The positions at which the inner metal fin 61b and the smoke deflector 61a8 are cut off are the same as the protrusion of the vertical metal fin 71b from the vertical resin frame base 72a1 in the metal frame 71. The length of the resin frame 72 is set so that the position of its end face approximately coincides with the position of the end face of the inner metal fin 61b.

[0036] When the end of the upper frame 22A, whose end has been processed in advance as described above, is joined to the end of the vertical frame 24A, the inner metal frame base 61a is inserted between the vertical metal fin portion 71b and the vertical resin fin portion 72b, and the end face of the inner metal frame base 61a abuts the vertical metal frame base portion 71a1, as shown in Figures 17 to 20. Therefore, from this state, if a screw is threaded into the screw hole 61a5 of the upper frame 22A through the vertical metal frame base portion 71a1, the metal frame portion 61 of the upper frame 22A and the metal frame portion 71 of the vertical frame 24A can be connected. At this time, the end face of the inner metal fin portion 61b abuts against the extending edge portion of the vertical metal fin portion 71b, and the end face of the inner resin fin portion 62b abuts against the protrusion portion 72c on the inside of the vertical resin fin portion 72b, so that no gaps are created between the facing surfaces facing outside and the facing surfaces facing inside. An inner sliding piece 90 is attached to the end of the vertical stile 24A to cover it.

[0037] The inner sliding piece 90 is molded from resin and covers the end face of the vertical stile 24A and the end face of the inner resin stile base 62a of the upper stile 22A, which protrudes above the end face of the vertical stile 24A. It is sized to protrude outward from the projection surface on the outer periphery of the vertical stile 24A. The projection dimension of the inner sliding piece 90 from the inner stile 20A is set so as to fill the gap for the push-in mechanism between the vertical door projection walls 13A2a, 14A2a of the vertical door frames 13, 14 and the projection surface of the vertical stile 24A without interfering with the smooth movement of the inner stile 20A. This inner sliding piece 90 can be attached to the inner stile 20A by screwing a screw into the metal stile portion 61 of the upper stile 22A from the outer periphery through a screw insertion hole (not shown).

[0038] As shown in Figure 23, an outer lower sliding piece 100 molded from resin is attached to the connecting portion between the lower frame 23B and the vertical frame 24B of the outer shoji screen 20B. This outer lower sliding piece 100 covers the end face of the vertical frame 24B from the projection surface on the outer periphery of the lower frame 23B and is configured to protrude outward from both the projection surface on the outer periphery of the vertical frame 24B and the projection surface on the outer periphery of the lower frame 23B. The projection dimension of the outer lower sliding piece 100 from the projection surface of the vertical frame 24B is approximately the same as that of the outer sliding piece 80. This outer lower sliding piece 100 has a water discharge hole 102 in an attachment wall portion 101 for attachment to the projection surface on the outer periphery of the lower frame 23B, and a wire engagement groove 104 in a protruding plate portion 103 that protrudes beyond the projection surface of the vertical frame 24B. The water discharge hole 102 is formed so as to penetrate the mounting wall 101 in a portion corresponding to the area between the vertical metal fin portion 71b and the vertical resin fin portion 72b of the vertical stile 24B. The wire engagement groove 104 penetrates the protruding plate portion 103 of the outer lower sliding piece 100 from top to bottom and opens to the outer peripheral surface of the protruding plate portion 103. One end of the wire 30 passes through this wire engagement groove 104 and is attached to the underside of the outer lower sliding piece 100. Although not shown in the figure, the other end of the wire 30 is connected to a connecting piece 110 (see Figure 3) provided on the vertical stile 24A of the inner screen 20A. Although not shown in the figure, the connecting piece 110 can be attached to any position on the vertical stile 24A by inserting it into the open end of the guide groove 71c provided in the vertical stile 24A.

[0039] With the fittings configured as described above, the end faces of the metal fins 51b, 61b of the upper frames 22A, 22B abut against the extended edge of the vertical metal fin 71b of the vertical frames 24A, 24B, and the end faces of the plastic fins 52b, 62b of the upper frames 22A, 22B abut against the extended edge of the vertical plastic fin 72b of the vertical frames 24A, 24B, so there is no need to cut out the vertical metal fins 71b and vertical plastic fins 72b of the vertical frames 24A, 24B. Furthermore, there is no need to cut out or otherwise process the plastic frames 52, 62 of the upper frames 22A, 22B. Similarly, in the inner shoji screen 20A, the end face of the outer metal fin portion 51b of the lower frame 23A abuts against the extended edge of the vertical metal fin portion 71b of the vertical frame 24A, and the end face of the inner plastic fin portion 62b of the lower frame 23A abuts against the extended edge of the vertical plastic fin portion 72b of the vertical frame 24A, so there is no need to cut out the vertical metal fin portion 71b and the vertical plastic fin portion 72b of the vertical frame 24A. Furthermore, there is no need to cut out a portion of the plastic frame portion 52 of the lower frame 23A.

[0040] This allows the connection between the vertical frame 24A and the upper frame 22A, 22B and the lower frame 23A to be achieved by simply processing the metal frame portions 51, 61 and 51, respectively, facilitating the assembly of the ventilation screens 20A, 20B. Furthermore, the ends of the vertical frames 24A, 24B are covered by the sliding pieces 80, 90, and 100 that guide the movement of the ventilation screens 20A, 20B. This eliminates the need to increase the number of components and reduces the risk of compromising the appearance. Furthermore, the outer screen 20B has a gutter 53 formed by providing a resin edge protrusion wall 52a4 and a metal edge protrusion wall 51a6 on the upper surface of the upper frame 22B. Therefore, even if water, such as rainwater, drips onto the upper surface of the upper frame 22B outdoors, it will not leak onto the surface of the outer screen 20B. Furthermore, drainage holes 83 are provided in the outer sliding pieces 80 provided at both ends of the gutter section 53. Therefore, water in the gutter section 53 is discharged through the drainage holes 83, and does not accumulate on the upper surface of the upper frame 22B. The water discharged from the drainage holes 83 into the inside of the vertical frame 24B is guided sequentially downward inside the vertical frame 24B, and then discharged to the outside of the outer screen 20B through the water discharge holes 102 provided in the outer lower sliding piece 100.

[0041] Figure 24 shows a schematic diagram of the manufacturing procedure for the door panel 2 of the above-mentioned fixture. That is, when assembling the door panel 2, first, as shown in Figure 24(a), the door frame body 10 is constructed by assembling the upper door frame 11, the lower door frame 12, and the left and right vertical door frames 13, 14 around all four sides, and then the inner shoji screen 20A and the outer shoji screen 20B are individually assembled by attaching the upper frames 22A, 22B, the lower frames 23A, 23B, and the left and right vertical frames 24A, 24B around the rectangular double-glazed glass 21A, 21B. At this time, the outer sliding piece 80, the inner sliding piece 90, and the outer lower sliding piece 100 are not yet attached to the inner shoji screen 20A and the outer shoji screen 20B.

[0042] From this state, as shown in Figure 24(b), the door frame 10 is placed on the floor, and one of the ventilation screens, e.g., the inner screen 20A, is installed on the door frame 10 by pushing it in on both sides. For the inner screen 20A placed on the door frame 10, as shown in Figure 24(c), a connecting piece 110 is attached to the guide groove 71c of the vertical stile 24A, and an inner sliding piece 90 and an outer sliding piece 80 are attached to the four corners. By appropriately moving the inner screen 20A relative to the door frame 10, a large gap can be created between the upper door frame 11 and the upper stile 22A and between the lower door frame 12 and the lower stile 23A. Therefore, by placing tools in these gaps, the installation of the connecting piece 110, the inner sliding piece 90, and the outer sliding piece 80 can be easily performed. When attaching the connecting piece 110, one end of the wire 30 is connected to the connecting piece 110 in advance, and then the wire 30 is inserted into the guide groove 71c from the lower end of the vertical stile 24A. The inner shoji screen 20A with the inner sliding piece 90 and outer sliding piece 80 attached fills the gap for the kendon secured between the vertical door projection walls 13A2a, 14A2a of the vertical door frames 13, 14 and the projection surface of the vertical stile 24A, so it will not accidentally fall off the door frame body 10 or rattle.

[0043] Next, as shown in Figure 24(d), the door frame 10 is turned over, and as shown in Figures 24(e) and 24(f), the outer screen 20B is fitted to the door frame 10 by pushing it left and right. For the outer screen 20B placed on the door frame 10, outer sliding pieces 80 and outer lower sliding pieces 100 are attached to the four corners, as shown in Figures 24(g) and 24(h). By appropriately moving the outer screen 20B relative to the door frame 10, it is possible to ensure large gaps between the upper door frame 11 and the upper stile 22B and between the lower door frame 12 and the lower stile 23B. Therefore, by placing tools in these gaps, the outer sliding pieces 80 and outer lower sliding pieces 100 can be easily installed. The outer sliding screen 20B, to which the outer sliding piece 80 and the outer lower sliding piece 100 are attached, fills the gap for the kendon secured between the vertical door projection walls 13A2a, 14A2a of the vertical door frames 13, 14 and the projection surface of the vertical stile 24B, and will not accidentally fall off or rattle from the door frame body 10. Finally, by attaching the other end of the wire 30 to the outer lower sliding piece 100, the assembly work of the door panel 2 is completed.

[0044] In the door panel 2 configured as described above, the sliding pieces 80, 90, and 100 are provided on the inner and outer shrouds 20A and 20B after they are installed in the door frame 10 with a kendon. This eliminates the risk of the ventilation shrouds 20A and 20B rattling relative to the door frame 10, facilitating assembly without interfering with opening and closing. Furthermore, the inner and outer shrouds 20A and 20B are configured with double-glazed glass 21A and 21B without the use of a batten, which is advantageous in terms of fire resistance. Furthermore, the inner and outer shrouds 20A and 20B can be removed from the door frame 10 in the reverse order of the previous procedure. Therefore, even if the double-glazed glass 21A and 21B need to be replaced, this can be done without disassembling the door frame 10, which is advantageous in terms of maintenance.

[0045] In the above-described embodiment, the door frame 10 and the ventilation shoji screens 20A, 20B provided on the door panel 2 are exemplified, but the present invention can also be applied to a frame and shoji screens provided on a main body. Also, although the shoji screens 20A, 20B are exemplified as being movable up and down, the present invention can also be applied to shoji screens that move left and right. Furthermore, although the sliding pieces 80, 90, 100 are used as end members, the sliding pieces do not necessarily have to be end members.

[0046] As described above, the fitting according to the present invention is a fitting comprising a shoji screen in which a frame material provided around a surface material comprises a metal frame portion molded from metal and a resin frame portion molded from resin, the metal frame portion has a metal frame base portion arranged on the outer periphery of the surface material and a metal fin portion extending from the metal frame base in the find direction, the resin frame portion has a resin frame base portion arranged on the outer periphery of the surface material and a resin fin portion extending from the resin frame base in the find direction, and the edge of the surface material is housed between the metal fin portion and the resin fin portion, The first and second frames that are connected are characterized in that the metal frame bases are connected to each other in a state in which the end face of the metal fin portion of the first frame abuts against the extended edge portion of the metal fin portion of the second frame and the end face of the metal frame base of the first frame abuts against the expected surface on the inner periphery of the metal frame base of the second frame, the end face of the resin fin portion of the first frame abuts against the extended edge portion of the resin fin portion of the second frame, and an end member is provided at the end of the second frame in a state in which it covers the portion of the metal frame portion of the first frame that is contained in the second frame. According to this invention, the end face of the metal fin portion of the first frame member abuts against the extended edge of the metal fin portion of the second frame member, and the end face of the resin fin portion of the first frame member abuts against the extended edge of the resin fin portion of the second frame member, so there is no need to cut out the metal fin portion and the resin fin portion of the second frame member. This means that the first frame member and the second frame member can be connected by processing only the first frame member, making it easier to assemble the shoji screen.

[0047] Furthermore, the present invention is characterized in that, in the above-mentioned fittings, the end member protrudes outward from the projecting surface of the second frame member and functions as a sliding piece that serves as a guide when the shoji screen is moved relative to the frame body. According to this invention, since the sliding piece is used as the end member, there is no need to provide a separate end member, and the number of parts can be reduced.

[0048] Furthermore, the present invention is characterized in that in the above-mentioned fitting, the end member is provided with a drainage hole at a position communicating with the inside of the second frame member. According to this invention, it is possible to prevent water such as rainwater from accumulating on the top surface of the shoji screen.

[0049] Furthermore, the present invention is characterized in that, in the above-mentioned building fixture, the projected surface on the outer periphery of the first frame member is provided with edge protrusions that protrude outward from both edge portions on both sides, and the end member is provided with the drainage holes at positions corresponding to the spaces between the edge protrusions. According to this invention, water such as rainwater dripping onto the top surface of the shoji screen is reliably guided to the drainage hole by the edge protrusion without leaking out onto the surface side of the shoji screen.
