Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the case of a fitting described in Patent Document 1, in which the portion from the finding surface facing the interior of the outdoor rail to the outdoor side is covered with an integral resin profile, there is a concern that the parts become large-sized and handling becomes complicated. Further, when the parts become large-sized, the influence of molding errors also becomes large, and there is also a possibility that the workability at the time of assembly becomes complicated.

[0005] On the other hand, if the resin profile is divided into an exterior portion that covers the space between the rails from the exterior rail's facing surface to the interior, as described in Patent Document 2, and an interior portion that covers the space between the interior rail's facing surface to the interior portion, the above-mentioned problems caused by the enlargement of the parts can be prevented. However, if the shoji screen moves in the depth direction relative to the frame due to the influence of wind pressure, for example, there is a concern that the resin profile pressed by the shoji screen may shift position relative to the metal profile and fall off the metal profile.

[0006] In view of the above circumstances, the present invention aims to provide a building component that can prevent problems caused by the enlargement of parts without causing the resin profile to fall off. [Means for solving the problem]

[0007] To achieve the above objective, the joinery according to the present invention comprises a frame body in which left and right vertical frames, an upper frame, and a lower frame are assembled on all four sides, and an interior sash and an exterior sash arranged on the frame body in a state where they slide in the extending direction of the upper frame, wherein the upper frame comprises a metal profile formed from metal and a resin profile formed from resin, and the upper frame is provided with an inner horizontal rail that guides the sliding of the interior sash and an outer horizontal rail that guides the sliding of the exterior sash, and the horizontal rail is made of metal The upper frame is composed of a metal rail portion provided on a metal profile and a resin rail portion provided on the resin profile. The resin profile of the upper frame includes an outer resin molded body in which the resin rail portion of the outer horizontal rail and the portion of the inner horizontal rail that constitutes the resin rail portion are integrally molded. The outer resin molded body has a recess formed to accommodate the metal rail portion of the inner horizontal rail, and the metal rail portion and the outer resin molded body that constitutes the recess are provided with engaging portions that engage with each other. The metal profile of the upper frame has a first metal portion that constitutes the metal rail portion of the inner horizontal rail, a second metal portion that extends inward from the outer periphery side of the first metal portion, a third metal portion that constitutes the metal rail portion of the outer horizontal rail, and a fourth metal portion that extends inward from the outer periphery side of the third metal portion and is connected to the outer periphery side of the first metal portion. The outer resin molded body of the upper frame has a first cover portion that constitutes the resin rail portion of the outer horizontal rail by covering the interior-facing surface of the third metal portion, and a second cover portion that covers the fourth metal portion by extending inward from the outer periphery side of the first cover portion. The first metal part and the fifth cover part are integrally molded, and the engagement portion is provided on the first metal part and the fifth cover part. The third cover part extends inward from the extended edge of the second cover part and covers the visible surface of the first metal part facing the outside, thereby constituting the resin rail portion of the inner horizontal rail. The fourth cover part extends inward from the edge located on the inner side of the third cover part and covers the surface on the inner side of the first metal part, thereby constituting the resin rail portion of the inner horizontal rail. The fifth cover part extends outward from the extended edge of the fourth cover part and constitutes the resin rail portion of the inner horizontal rail, and the third cover part and the fourth cover part together constitute the recess. It is characterized by having this feature. [Effects of the Invention]

[0008] According to the present invention, by integrally molding the resin rail portion of the outer horizontal rail to the portion constituting the resin rail portion of the inner horizontal rail as an outer resin molded body, it is possible to prevent situations where handling becomes complicated or assembly work becomes complicated due to the enlargement of the parts. Moreover, since the outer resin molded body is provided with a recess for housing the metal rail portion, and the metal rail portion and the outer resin molded body are engaged with each other by an engaging portion in the recess, even if the shoji screen moves in the depth direction relative to the frame due to the influence of wind pressure, the outer resin molded body pressed by the shoji screen is less likely to shift position relative to the metal profile, and the situation in which it falls off the metal profile can be prevented.

[0010] The following describes in detail preferred embodiments of the joinery according to the present invention with reference to the attached drawings. For convenience, the terms "depth direction" and "face direction" may be used below. The depth direction is the direction along the depth of the joinery, as indicated by arrow A in the figure. The surface along the depth direction may be referred to as the depth surface. The face direction is the direction along the vertical direction perpendicular to the depth direction, in the case of a frame that extends horizontally, such as a bottom frame. In the case of a frame that extends vertically, such as a vertical frame, the face direction is the direction along the horizontal direction perpendicular to the depth direction. The surface along the face direction may be referred to as the face surface.

[0011] Figures 1 to 3 show a window that is an embodiment of the present invention. The window described here is called a sliding window and comprises a frame 10, an outer sash 20A installed on the exterior side of the frame 10, and an inner sash 20B installed on the interior side of the frame 10. The frame 10 is constructed in a rectangular shape by assembling left and right vertical frames 11, 12, an upper frame 13, and a lower frame 14 around the four sides. The outer sash 20A is constructed with a rectangular double-glazed glass pane 21A and vertical frames 22A, an upper frame 23A, a lower frame 24A, and a vertical frame 25A installed around the four sides of the double-glazed glass pane 21A. Similarly, the inner sash 20B is constructed with a rectangular double-glazed glass pane 21B and vertical frames 22B, an upper frame 23B, a lower frame 24B, and a vertical frame 25B arranged around the four sides of the double-glazed glass pane 21B. In this embodiment, the outer sash 20A and the inner sash 20B are arranged to move along the longitudinal sides of the upper frame 13 and lower frame 14 relative to the frame 10, and when viewed from the interior side, the outer sash 20A is placed on the left side of the frame 10 and the inner sash 20B is placed on the right side, making it possible to close the opening of the frame 10. When the opening of the frame 10 is closed, the vertical frame located to the right of the outer sash 20A (hereinafter referred to as the meeting frame 25A) and the vertical frame located to the left of the inner sash 20B (hereinafter referred to as the meeting frame 25B) meet and are arranged side by side in the depth direction when viewed from the interior side. The vertical frames 22A, 22B, upper frames 23A, 23B, lower frames 24A, 24B, and meeting frames 25A, 25B that make up the sashes 20A, 20B are all extruded profiles molded from resin, and are configured to have a cross-sectional shape that is almost uniform along the entire length of the longitudinal side. In this embodiment, the shoji screens 20A and 20B are constructed using vertical frames 22A and 22B, upper frames 23A and 23B, and lower frames 24A and 24B that have the same cross-sectional shape and the same hue. The meeting frames 25A and 25B have the same hue as the vertical frames 22A, but have a different cross-sectional shape. In contrast, the vertical frames 11 and 12, upper frame 13, and lower frame 14 that constitute the frame body 10 are of a composite type, comprising metal profiles made from extruded profiles formed from metal such as aluminum alloy, and resin profiles made from extruded profiles formed from resin.The metal and resin profiles are also constructed to have a cross-sectional shape that is substantially uniform along their entire length.

[0012] The following describes in detail the configuration of the vertical frames 11, 12, upper frame 13, and lower frame 14 that constitute the frame and frame body 10 of the shoji screens 20A and 20B, and also explains the characteristic features of the present invention. As mentioned above, the frames 22A, 22B, 23A, 23B, 24A, and 24B of the shoji screens 20A and 20B are identical, so only the vertical frame 22A of the outer shoji screen 20A will be described, and the other frames will be given the same reference numerals. The meeting frames 25A and 25B are almost identical, so only the meeting frame 25A of the outer shoji screen 20A will be described, and the meeting frame 25B of the inner shoji screen 20B will be given the same reference numerals. Also, for convenience, in the following, the vertical frame located on the left side when viewed from the interior side will be referred to as the left vertical frame 11, and the vertical frame located on the right side will be referred to as the right vertical frame 12.

[0013] (Stile 22A) As shown in Figure 3, the vertical frame 22A is formed by integrally molding a frame base 31, a glass clamping piece 32, an inner rail guide 33, and an outer rail guide 34. The frame base 31 has a hollow shape with a roughly square cross-section. A glazing strip 35 is provided on the outer edge of the inner circumference of the frame base 31 via a glazing strip mounting groove 31a. The glazing strip 35 clamps the double-glazed glass 21A between itself and the glass clamping piece 32. The glass clamping piece 32 protrudes inward from the inner edge of the frame base 31 that faces the interior. The inner rail guide 33 protrudes outward from the outer edge of the frame base 31 that faces the interior, and the outer rail guide 34 protrudes outward from the outer edge of the frame base 31 that faces the exterior. The inner rail guide 33 and the outer rail guide 34 have a gap between them, and a tight material 36 is provided on the parts facing each other. The tight material 36 extends from the outer circumference of the inner rail guide 33 and the outer rail guide 34 in a direction toward each other.

[0014] (Meeting frame 25A) The summons frame 25A is formed by integrally molding a frame base portion 31 and a glass holding piece 32. The frame base portion 31 has a hollow shape with a substantially square cross-section. An edge pressing member 35 is provided on the edge on the outdoor side on the inner peripheral side of the frame base portion 31 via an edge pressing mounting groove 31a. The edge pressing member 35 sandwiches a multilayer glass 21A between itself and the glass holding piece 32. The glass holding piece 32 protrudes inward from the edge on the indoor side on the inner peripheral side of the frame base portion 31.

[0015] (Left vertical frame 11) As shown in Figures 3 and 4, the metal profile 40 of the left vertical frame 11 is integrally molded with the left frame base 41, the left inner end facing plate 42, the left fixing facing plate 43, and the left rail projection 44. The left frame base 41 is a flat plate extending along the depth direction. The left inner end facing plate 42 is a flat plate extending outward from the edge located on the indoor side of the left frame base 41. The left fixing facing plate 43 is a flat plate extending outward from the left frame base 41. In the illustrated example, the left fixing facing plate 43 is provided at approximately 1 / 3 of the length from the edge located on the indoor side of the left frame base 41. The length of this left fixing facing plate 43 extending outward from the left frame base 41 is set to be greater than that of the left inner end facing plate 42. The left rail projection 44 is for forming the metal rail portion of the outer vertical rail 11A corresponding to the outer sash 20A, and extends inward from the left frame base 41, and then extends inward in the depth direction toward the interior. The extension length of the left rail projection 44 is set so that when the outer sash 20A is positioned in the closed position relative to the frame 10, it extends beyond the tight material 36 provided on the vertical frame 22A which becomes the door edge and is located on the inner circumference side. The extension edge of the left rail projection 44 that extends toward the interior is provided with a left-side fitting portion 44a. The left-side fitting portion 44a is for restricting movement in the depth direction away from each other by fitting into the left-side fitting portion 52a of the resin profile 50, which will be described later. In the illustrated example, the left side fitting portion 44a of the left rail projection 44 is formed by extending outward from the extended edge located on the indoor side of the left rail projection 44, then bending inward, and further bending inward. The position where the left rail projection 44 is provided is approximately 1 / 4 of the way from the edge located on the outdoor side of the left frame base 41.

[0016] In the metal profile 40 of the left vertical frame 11, a plurality of left vertical claws 45 for attachment are provided at a portion on the inner peripheral side of the left frame base 41. The left vertical claws 45 for attachment are for maintaining the state in which a resin profile 50 described later is attached to the inner peripheral side of the left frame base 41. In the illustrated example, the left vertical claws 45 for attachment are provided at the edge portion located on the indoor side of the left frame base 41 and at the portion on the outer peripheral side of the left rail protrusion 44, respectively, and the left vertical claws 45 for attachment are provided at a portion substantially in the middle between the edge portion located on the indoor side of the left frame base 41 and the left rail protrusion 44.

[0017] The resin profile 50 of the left vertical frame 11 includes a left vertical resin molded body 50A and an inner peripheral cover body 50B that are molded separately from each other. These left vertical resin molded body 50A and inner peripheral cover body 50B each have a length that extends over the entire length of the portion located between the upper frame 13 and the lower frame 14 in the left vertical frame 11. Although not explicitly shown in the figure, the left vertical resin molded body 50A and the inner peripheral cover body 50B are configured to exhibit the same hue as the vertical frame 22A of the outer shutter 20A. However, it is not necessarily required that the left vertical resin molded body 50A and the inner peripheral cover body 50B exhibit the same hue as the vertical frame 22A of the outer shutter 20A.

[0018] The left vertical resin molded body 50A is formed by integrally molding the left cover base 51, the left rail cover portion 52, the left visible cover portion 53, and the left frame cover portion 54. The left cover base 51 is plate-shaped and covers the portion of the metal profile 40 that is on the interior side of the inner circumference side, beyond the left rail projection portion 44. The middle portion of the left cover base 51 is provided with a base-shaped portion 51a, a hollow portion 51b, and a hook portion 51c. The base-shaped portion 51a protrudes inward so as to form a space between it and the metal profile 40. The hollow portion 51b is a cylindrical shape with a roughly square cross-section, provided in the portion on the interior side of the base-shaped portion 51a, and is configured so that its visible surface facing the outside is approximately in the middle of the left frame base 41. The hollow portion 51b is provided with engaging projections 51d on the outer surface facing the outdoors and on the inner circumference of the inner surface facing the indoors. The hook portion 51c protrudes outward from the base portion 51a and then bends inward, and is positioned to correspond to the mounting left vertical claw portion 45 provided in the middle of the left frame base portion 41. The left cover base portion 51 is detachably attached to the left frame base portion 41 by inserting the outer edge portion facing outdoors between the mounting left vertical claw portion 45 provided on the left rail projection portion 44 and the left frame base portion 41, inserting the inner edge portion facing indoors between the indoor mounting left vertical claw portion 45 and the left frame base portion 41, and further engaging the hook portion 51c with the mounting left vertical claw portion 45 provided in the middle of the left frame base portion 41. The left rail cover portion 52 is intended to constitute the resin rail portion of the outer vertical rail 11A corresponding to the outer sash 20A, and extends inward from the left cover base 51. The edge of the left rail cover portion 52 on the inner side is provided with a left-side fitting portion 52a. The left-side fitting portion 52a extends outward from the extended edge of the left rail cover portion 52 and then bends outward. The left rail cover portion 52 covers the interior-facing surface of the left rail protrusion 44 by fitting the left-side fitting portion 52a to the left-side fitting portion 44a of the left rail protrusion 44, while maintaining a space between the left rail protrusion 44 and the left rail protrusion 44. The left visible cover portion 53 extends inward from the interior-facing edge of the left cover base 51. The left frame cover portion 54 extends in the depth direction toward the interior from the inner edge of the left visible cover portion 53.

[0019] The inner circumferential cover body 50B is formed by integrally molding a cover plate portion 55, an outer clamping plate portion 56, and an inner clamping plate portion 57. The cover plate portion 55 is a plate shape that extends along the depth direction and is formed to a length corresponding to the dimension from the left visible cover portion 53 to the visible surface of the hollow portion 51b facing the outside. The outer clamping plate portion 56 extends outward from the edge of the cover plate portion 55 that is located on the outside. The inner clamping plate portion 57 clamps the hollow portion 51b between itself and the outer clamping plate portion 56 and extends outward from the cover plate portion 55. The outer clamping plate portion 56 and the inner clamping plate portion 57 are provided with locking projections 56a and 57a on the outer peripheral edges facing each other, and the inner clamping plate portion 57 is provided with a contact piece 57b facing outwards on the portion that is on the inner peripheral side of the locking projection 57a. The inner peripheral cover body 50B is attached to the inner peripheral side of the hollow portion 51b by engaging the locking projections 56a of the outer clamping plate portion 56 and 57a of the inner clamping plate portion 57 with the engaging projection 51d. When the outer edge of the outer clamping plate portion 56 is brought into contact with the base portion 51a, and the contact piece 57b of the inner clamping plate portion 57 is brought into contact with the inner surface of the hollow portion 51b, the inner surface of the cover plate portion 55 and the inner surface of the left frame cover portion 54 are positioned on substantially the same plane. In other words, in the left vertical frame 11 located on the door edge side of the outer sliding door 20A, the left frame cover portion 54 and the inner cover body 50B are positioned so as to be continuous with substantially no step difference.

[0020] (Right vertical frame 12) As shown in Figures 3 and 5, the metal profile 60 of the right vertical frame 12 is integrally molded with the right frame base 61, the right inner end facing plate 62, the right fixing facing plate 63, the right rail projection 64, and the door stop plate 65. The right frame base 61 is a flat plate extending along the depth direction, and is configured so that its dimensions along the depth direction are approximately the same as those of the left frame base 41. The right inner end facing plate 62 is a flat plate extending outward from the edge located on the indoor side of the right frame base 61. The right fixing facing plate 63 is a flat plate extending outward from the right frame base 61, and is positioned on approximately the same plane as the left fixing facing plate 43. The projection 64 for the right rail is for forming the metal rail portion of the inner vertical rail 12B corresponding to the inner sash 20B, and extends inward from the right frame base 61. The extended edge of the projection 64 for the right rail that extends inward is provided with a right-side fitting portion 64a. The right-side fitting portion 64a is for restricting movement in the direction of separation from each other by fitting into the right-side fitting portion 72a of the resin profile 70, which will be described later. In the illustrated example, the right-side fitting portion 64a is formed by extending inward from the extended edge of the projection 64 for the right rail and then bending inward. The position where the projection 64 for the right rail is provided is approximately the same as the position of the right fixing face plate portion 63. The door stop plate portion 65 extends inward from the right frame base 61 and is provided at a position approximately midway along the right frame base 61.

[0021] The metal profile 60 of the right vertical frame 12 is provided with multiple mounting right vertical claws 66 on the inner circumference side of the right frame base 61. The mounting right vertical claws 66 are for maintaining the state in which the resin profile 70, described later, is attached to the inner circumference side of the right frame base 61. In the illustrated example, the mounting right vertical claws 66 are provided on the edge on the indoor side of the right frame base 61 and on the outer circumference side of the projection 64 for the right rail.

[0022] The resin profile 70 of the right vertical frame 12 has a length that extends along the entire length of the portion located between the upper frame 13 and the lower frame 14 of the right vertical frame 12, and is configured to exhibit the same hue as the vertical frame 22A of the outer sash 20A. This resin profile 70 of the right vertical frame 12 is constructed by integrally molding the right cover base 71, the right rail cover portion 72, the right visible cover portion 73, and the right frame cover portion 74. The right cover base 71 is a flat plate that covers the portion of the metal profile 60 that is on the interior side of the inner circumference, beyond the right rail projection 64. The right cover base 71 is detachably attached to the right frame base 61 by inserting its outer edge between the right vertical claw portion 66 provided on the right rail projection 64 and the right frame base 61, and inserting its inner edge between the right vertical claw portion 66 on the indoor side and the right frame base 61. The right rail cover portion 72 is for forming the resin rail portion of the inner vertical rail 12B corresponding to the inner sash 20B, and extends inward from the right cover base 71 before extending outward. The inner edge of the right rail cover portion 72 is provided with a right-side fitting portion 72a. The right-side fitting portion 72a is bent outward from the extended edge of the right rail cover portion 72. The right rail cover portion 72 covers the interior-facing surface of the right rail protrusion 64 by fitting its right-side fitting portion 72a to the right-side fitting portion 64a of the right rail protrusion 64, while maintaining a space between the right rail protrusion 64 and the cover portion 72. The right exterior cover portion 73 extends inward from the interior-facing edge of the right cover base portion 71. The right frame cover portion 74 extends inward in the depth direction from the interior-facing edge of the right exterior cover portion 73. However, the resin profile 70 of the right vertical frame 12 does not necessarily have to be the same hue as the vertical frame 22A of the outer sash 20A.

[0023] (Top frame 13) As shown in Figures 2 and 6, the metal profile 80 of the upper frame 13 is composed of an inner upper metal molded body 80A on the indoor side and an outer upper metal molded body 80B on the outdoor side. These inner upper metal molded body 80A and outer upper metal molded body 80B are connected to each other by a bridge material 80C formed from insulating material, and are thermally isolated from each other without contact.

[0024] The inner upper metal molded body 80A is formed by integrally molding an upper inner viewing plate portion (second metal portion) 81, an upper inner facing plate portion (first metal portion) 82, and an upper inner pocket portion 83. The upper inner viewing plate portion 81 is a plate shape that extends along the viewing direction.

The extended length of the metal rail base portion 82a is set so that, when the inner sash 20B is installed in the frame 10, it is on the outer periphery side of the contact position of the tight material 36 provided on the upper frame 23B. The inclined extended portion 82b is inclined so that it gradually moves outward toward the interior side. The edge of the extension portion 82d located on the indoor side extends to a position that is an extension of the metal rail base portion 82a, while the edge of the projection portion 82e located on the indoor side extends to a position that protrudes slightly more inward than the extension portion 82d. The visible extension portion 82c and the extension portion 82d are provided with abutment projections 82f. The abutment projections 82f are protruding portions provided on the visible surface of the visible extension portion 82c facing the outside and on the inner circumference surface of the extension portion 82d. The upper inner pocket portion 83 is a groove-shaped recess for accommodating the bridge material 80C and is provided to open to the outside at the edge of the upper inner projection plate portion 81 that faces the outside.

[0025] The inner upper metal molded body 80A is provided with a plurality of internal engagement receiving parts 81a and 82g on the inner circumference side of the upper inner facing plate portion 81. The internal engagement receiving parts 81a and 82g are for maintaining the state in which the resin profile 90, described later, is attached to the inner circumference side of the upper inner facing plate portion 81. In the illustrated example, the internal engagement receiving parts 81a and 82g are provided on the edge portion located on the indoor side of the upper inner facing plate portion 81 and on the outer circumference side of the metal rail base portion 82a of the upper inner facing plate portion 82, respectively.

[0026] The outer upper metal molded body 80B is formed by integrally molding the upper outer viewing plate portion (fourth metal portion) 84, the upper outer face plate portion (third metal portion) 85, the upper outer pocket portion 86, the upper fixing face plate portion 87, and the upper outer cover plate portion 88. The upper outer viewing plate portion 84 is a plate shape that extends along the viewing direction. The upper outer face plate portion 85 constitutes the metal rail portion of the outer upper horizontal rail 13A for guiding the outer sash 20A, and extends from the outer edge of the upper outer viewing plate portion 84 toward the inner circumference, and then extends toward the indoor side. An upper fitting portion 85a is provided on the extended edge of the upper outer face plate portion 85 that extends toward the indoor side. The upper fitting portion 85a is for restricting movement in the viewing direction away from each other by fitting into the upper fitting portion 97a of the resin profile 90, which will be described later. In the illustrated example, the upper fitting portion 85a is formed by extending outward from the extended edge of the upper outer facing plate portion 85, then bending inward toward the interior, and further bending inward toward the interior. The upper outer pocket portion 86 is a groove-shaped recess for accommodating the bridge material 80C, and is provided to open into the interior at the interior-facing edge of the upper outer facing plate portion 84. The upper fixing facing plate portion 87 is a flat plate that extends outward from the upper outer pocket portion 86. The upper outer cover plate portion 88 extends inward from the exterior-facing edge of the upper outer facing plate portion 84.

[0027] The outer upper metal molded body 80B is provided with a plurality of upper engagement receiving portions (engagement receiving portions) 84a on the inner circumference side of the upper outer facing plate portion 84, and a plurality of thickened portions 84b in the portions between the upper engagement receiving portions 84a. The upper engagement receiving portions 84a are for maintaining the state in which the resin profile 90, described later, is attached to the inner circumference side of the upper outer facing plate portion 84. In the illustrated example, upper engagement receiving portions 84a are provided on the portion of the upper outer pocket portion 86 facing the outside, and on the facing surface of the upper outer facing plate portion 84, on the portion that is on the indoor side of the upper outer visible plate portion 85. The thickened portions 84b are constructed by partially increasing the plate thickness of the upper outer facing plate portion 84, and are provided along the longitudinal side of the upper frame 13.

[0028] The resin profile 90 of the upper frame 13 is composed of an inner upper resin molded body (inner resin molded body) 90A on the indoor side and an outer upper resin molded body (outer resin molded body) 90B on the outdoor side. These inner upper resin molded bodies 90A and outer upper resin molded bodies 90B each have a length that extends over the entire length of the portion located between the left and right vertical frames 11 and 12 on the upper frame 13. Although not explicitly shown in the figure, the inner upper resin molded body 90A and outer upper resin molded body 90B are configured to exhibit the same hue as the vertical frame 22A of the outer sash 20A. However, the inner upper resin molded body 90A and outer upper resin molded body 90B do not necessarily have to exhibit the same hue as the vertical frame 22A of the outer sash 20A.

[0029] The inner upper resin molded body 90A is formed by integrally molding the upper inner cover base (seventh cover portion) 91, the upper inner rail cover portion (sixth cover portion) 92, the upper visible cover portion 93, the upper frame cover portion 94, and the extension cover portion 95. The upper inner cover base portion 91 is a flat plate that covers the upper inner visible plate portion 81 of the metal profile 80. This upper inner cover base portion 91 is detachably attached to the inner upper metal molded body 80A by inserting the outer edge portion between the upper engagement receiving portion 84a provided on the metal rail base portion 82a and the upper inner visible plate portion 81, and inserting the inner edge portion between the upper engagement receiving portion 84a on the indoor side and the upper inner visible plate portion 81. The upper inner rail cover portion 92, together with the outer cover portion (third cover portion) 98, the inner circumferential cover portion (fourth cover portion) 99, and the inner cover portion (fifth cover portion) 100 for the upper inner rail of the outer upper resin molded body 90B (described later), constitutes the resin rail portion of the upper horizontal rail 13B corresponding to the inner sash 20B, and extends inward from the upper inner cover base portion 91. The inner edge portion of the upper inner rail cover portion 92 is configured to be approximately the same as the metal rail base portion 82a of the upper inner facing plate portion 82 when the upper inner cover base portion 91 is brought into contact with the upper inner facing plate portion 81. The outer circumferential portion of the upper inner rail cover portion 92 is provided with an engaging projection 92a for engaging with the engaging receiving portion 82g. The upper facing cover portion 93 extends inward from the indoor-facing edge portion of the upper inner cover base portion 91. The outer circumferential portion of the upper visible cover portion 93 is provided with an engaging projection 93a for engaging with the engaging receiving portion 81a. The upper frame cover portion 94 extends in the depth direction toward the interior from the inner edge of the upper visible cover portion 93. The extension cover portion 95 extends inward from the outer edge of the upper frame cover portion 94. The extended edge of the extension cover portion 95 extends to a position further inward than the inner edge of the upper inner rail cover portion 92.

[0030] The outer upper resin molded body 90B is formed by integrally molding the upper outer cover base (second cover portion) 96, the inner cover portion for the upper outer rail (first cover portion) 97, the outer cover portion for the upper inner rail 98, the inner circumference cover portion for the upper inner rail 99, and the inner cover portion for the upper inner rail 100. The upper outer cover base 96 is a flat plate that covers the upper outer facing plate portion 84 of the metal profile 80. The inner cover portion for the upper outer rail 97 is for forming the resin rail portion of the upper horizontal rail 13A corresponding to the outer sash 20A, and extends inward from the edge located on the outdoor side of the upper outer cover base 96. An upper fitting portion 97a is provided on the edge on the inner circumference side of the inner cover portion for the upper outer rail 97. The upper fitting portion 97a extends outward from the extended edge of the inner cover portion for the upper outer rail 97 and then bends outward. The inner cover portion 97 for the upper outer rail covers the interior-facing surface of the upper outer facing plate portion 85 by fitting its upper fitting portion 97a into the upper fitting portion 85a of the upper outer facing plate portion 85, thereby securing a space between it and the upper outer facing plate portion 85. The outer cover portion 98 for the upper inner rail, the inner circumference cover portion 99 for the upper inner rail, and the inner cover portion 100 for the upper inner rail, together with the cover portion 92 for the upper inner rail of the inner upper resin molded body 90A, constitute the resin rail portion of the upper horizontal rail 13B corresponding to the inner sash 20B. The outer cover portion 98 for the upper inner rail extends inward from the edge located on the interior side of the upper outer cover base portion 96, thereby covering the exterior-facing surfaces of the metal rail base portion 82a, the inclined extension portion 82b, and the facing extension portion 82c of the upper inner facing plate portion 82. The inner circumferential cover portion 99 for the upper inner rail extends inward from the extended edge of the outer cover portion 98 for the upper inner rail, thereby covering the inner surface of the extended portion 82d. In other words, the inner circumferential cover portion 99 for the upper inner rail constitutes the portion of the resin profile 90 that is on the inner side of the inner upper horizontal rail 13B. The inner cover portion 100 for the upper inner rail extends outward from the extended edge of the inner circumferential cover portion 99 for the upper inner rail, thereby covering the visible surface of the portion of the upper inner visible plate portion 82 that is located on the inner side of the metal rail base portion 82a.The extension length of the inner cover portion 100 for the upper inner rail is set so that when the inner sash 20B is installed on the frame 10, the tight material 36 provided on the upper frame 23B does not come into contact with the upper inner rail cover portion 92 or the joint 101 with the upper inner rail cover portion 92. As is clear from the figure, the outer cover portion 98 for the upper inner rail, the inner circumference cover portion 99 for the upper inner rail, and the inner cover portion 100 for the upper inner rail form a recess 102 that opens on the outer circumference, and the inclined extension portion 82b, the visible extension portion 82c, the projection extension portion 82d, and the projection protrusion portion 82e of the upper inner facing plate portion 82 are housed inside. The inner cover portion 100 for the upper inner rail is provided with an intermediate engaging portion (engaging portion) 100a. The intermediate engaging portion 100a engages with the outer peripheral portion of the projecting portion 82e, thereby restricting the movement of the inner peripheral cover portion 99 for the upper inner rail toward the inner peripheral relative to the upper inner facing plate portion 82.

[0031] The outer upper resin molded body 90B is provided with a plurality of engaging protrusions 96a and support protrusions 96b on the outer peripheral side of the upper outer cover base 96, and the inner cover portion 97 for the upper outer rail and the outer cover portion 98 for the upper inner rail are provided with mounting protrusions 97b and 98a, respectively. The engaging protrusions 96a extend outward from the upper outer cover base 96 and have engaging claw portions 96c at their extended edges. The engaging claw portions 96c engage with the upper engaging receiving portion 84a provided on the outer upper metal molded body 80B, thereby maintaining the upper outer cover base 96 in a state where it covers the inner peripheral surface of the upper outer peripheral plate portion 84 while securing a space between it and the upper outer peripheral plate portion 84. The support protrusions 96b extend outward from the upper outer cover base 96 between the engaging protrusions 96a. The dimensions of the support projection 96b are set such that when the engaging claw portion 96c of the engaging projection 96a engages with the upper engaging receiving portion 84a, the extended edge is positioned close to the upper outer facing plate portion 84 between the thickened portions 84b provided on the upper outer facing plate portion 84. The mounting projections 97b and 98a protrude toward each other from the outer circumference of the inner cover portion 97 for the upper outer rail and the outer cover portion 98 for the upper inner rail. These mounting projections 97b and 98a engage with the upper windbreak member 110A when it is installed between the inner cover portion 97 for the upper outer rail and the outer cover portion 98 for the upper inner rail, thereby preventing the upper windbreak member 110A from falling off. The upper windbreak member 110A is molded from an elastic resin material and is installed on the inner circumference of the upper frame 13 in the portion corresponding to the meeting stiles 25A and 25B, thereby restricting the flow of air between the inside and outside of the room.

[0032] (Bottom frame 14) As shown in Figures 2, 7 to 10, the metal profile 120 of the lower frame 14 is composed of an inner lower metal molded body 120A on the indoor side and an outer lower metal molded body 120B on the outdoor side. These inner lower metal molded bodies 120A and outer lower metal molded bodies 120B are connected to each other by a bridge material 120C formed from insulating material, and are thermally isolated from each other without contact.

[0033] The inner lower metal molded body 120A is formed by integrally molding the lower inner depth plate portion 121, the lower inner face plate portion 122, the lower inner pocket portion 123, the lower inner end face plate portion 124, and the lower support plate portion 125. The lower inner depth plate portion 121 is a plate shape that extends along the depth direction. The lower inner face plate portion 122 constitutes the metal rail portion of the inner lower horizontal rail 14B for guiding the inner sash 20B, and extends inward from the outer edge of the lower inner depth plate portion 121, and then extends outward. The extended edge of the lower inner face plate portion 122 that extends inward is provided with a door roller guide portion 122a and a lower fitting portion 122b. The roller guide portion 122a is a protruding portion that extends inward and guides the sliding of the inner sash 20B via the roller 26B. The lower fitting portion 122b is designed to restrict movement in the depth direction away from each other by fitting into the lower fitting portion 142a of the resin profile 140, which will be described later. In the illustrated example, the lower fitting portion 122b is formed by extending outward from the extended edge located on the indoor side of the lower inner facing plate portion 122, bending inward, and then bending inward again. The lower inner pocket portion 123 is a groove-shaped recess for accommodating the bridge material 120C and is provided to open to the outside at the edge on the outdoor side of the lower inner facing plate portion 121. The lower inner end facing plate portion 124 extends along the depth direction from the edge on the indoor side of the lower inner facing plate portion 121. A lower fixing plate portion 126 is provided on the outer periphery side of the lower inner end facing plate portion 124, which is inclined to gradually become more outward toward the interior. The lower support plate portion 125 extends outward from the intermediate portion between the lower inner pocket portion 123 and the lower inner end facing plate portion 124 in the lower inner facing plate portion 121. The lower inner end facing plate portion 124, the lower fixing plate portion 126, and the lower support plate portion 125 are configured to be located on the same plane, with their respective outer edges being substantially horizontal along the facing direction.

[0034] The inner lower metal molded body 120A is provided with a plurality of lower engagement receiving portions 121a on the inner circumference side of the lower inner facing plate portion 121. The lower engagement receiving portions 121a are for maintaining the state in which the resin profile 140, described later, is attached to the inner circumference side of the lower inner facing plate portion 121. In the illustrated example, the lower engagement receiving portions 121a are provided on the facing surface of the lower inner end facing plate portion 124 that faces the outside, and on the facing surface of the lower inner facing plate portion 121, on the portion facing the lower fitting portion 122b.

[0035] The outer lower metal molded body 120B is formed by integrally molding the lower outer depth plate portion 127, the lower outer face plate portion 128, the lower outer pocket portion 129, and the lower outer cover plate portion 130. The lower outer depth plate portion 127 is a plate shape that extends along the depth direction. In the illustrated outer lower metal molded body 120B, a hollow portion 131 is formed in the outer peripheral portion of the lower outer depth plate portion 127. The lower outer face plate portion 128 constitutes the metal rail portion of the outer lower horizontal rail 14A for guiding the outer sash 20A, and extends from the outer edge of the lower outer depth plate portion 127 toward the inner circumference, and then extends toward the interior. The extended edge of the lower outer face plate portion 128 that extends toward the interior is provided with a door roller guide portion 128a and a lower fitting portion 128b. The roller guide portion 128a is a protruding portion that extends inward and guides the sliding of the outer sash 20A via the roller 26A. The lower fitting portion 128b is designed to restrict movement in the direction of separation from each other by fitting into the lower fitting portion 146a of the resin profile 140, which will be described later. In the illustrated example, the lower fitting portion 128b is formed by extending outward from the extended edge of the lower outer facing plate portion 128, bending inward, and then bending inward again. The edge located on the inner side of the lower outer facing plate portion 128 is configured to be approximately the same as the lower inner facing plate portion 122. The lower outer pocket portion 129 is a groove-shaped recess for accommodating the bridge material 120C and is provided to open into the room at the edge on the room side of the lower outer facing plate portion 127. The lower outer cover plate portion 130 extends inward from the outer edge of the lower outer projection plate portion 127.

[0036] The outer lower metal molded body 120B is provided with a plurality of lower engagement receiving portions 127a on the inner circumference side of the lower outer facing plate portion 127. The lower engagement receiving portions 127a are for maintaining the state in which the resin profile 140, described later, is attached to the inner circumference side of the lower outer facing plate portion 127. In the illustrated example, the lower engagement receiving portions 127a are provided on the portion of the lower outer pocket portion 129 facing the outside, and on the facing surface of the lower outer facing plate portion 127, on the portion facing the lower fitting portion 128b.

[0037] As shown in Figures 8 and 9, a lower windbreak member 110B is attached to the metal profile 120 of the lower frame 14 described above, between the lower inner facing plate portion 122 of the inner lower metal molded body 120A and the lower outer facing plate portion 128 of the outer lower metal molded body 120B. The lower windbreak member 110B is molded from an elastic resin material and is installed on the inner circumferential surface of the lower frame 14 in the portion corresponding to the meeting stiles 25A and 25B, in order to restrict the flow of air between the inside and outside.

[0038] The resin profile 140 of the lower frame 14 is composed of an inner lower resin molded body 140A on the indoor side and an outer lower resin molded body 140B on the outdoor side. Of these, the inner lower resin molded body 140A is configured to have a length that extends over the entire length of the portion located between the left and right vertical frames 11 and 12 in the lower frame 14. In contrast, the outer lower resin molded body 140B is configured to have a length that extends over the entire length of the portion located between the left vertical frame 11 and the lower windbreak member 110B in the lower frame 14. Although not explicitly shown in the figure, the inner lower resin molded body 140A and the outer lower resin molded body 140B are configured to exhibit the same hue as the vertical frame 22A of the outer sash 20A. However, the inner lower resin molded body 140A and the outer lower resin molded body 140B do not necessarily have to exhibit the same hue as the vertical frame 22A of the outer sash 20A.

[0039] The inner lower resin molded body 140A is formed by integrally molding the lower inner cover base 141, the lower inner rail cover portion 142, the lower visible cover portion 143, and the lower frame cover portion 144. The lower inner cover base 141 is a flat plate that covers the lower inner visible plate portion 121 of the metal profile 120. The lower inner rail cover portion 142 is for forming the resin rail portion of the lower horizontal rail 14B corresponding to the inner sash 20B, and extends inward from the lower inner cover base 141. A lower fitting portion 142a is provided on the inner edge of the lower inner rail cover portion 142. The lower fitting portion 142a extends outward from the extended edge of the lower inner rail cover portion 142, and then bends outward. The lower inner rail cover portion 142 covers the interior-facing surface of the lower inner surface plate portion 122 by fitting the lower fitting portion 142a of the lower inner surface plate portion 122 to the lower fitting portion 122b of the lower inner surface plate portion 122, while maintaining a space between the lower inner surface plate portion 122 and the lower inner surface plate portion 122. The lower surface cover portion 143 extends inward from the interior-facing edge of the lower inner cover base portion 141, thereby covering the exterior-facing surface of the lower inner end surface plate portion 124. The lower frame cover portion 144 extends inward in the depth direction from the interior-facing edge of the lower surface cover portion 143.

[0040] The inner lower resin molded body 140A is provided with a plurality of engaging protrusions 141a on the outer circumferential side of the lower inner cover base 141. The engaging protrusions 141a extend outward from the lower inner cover base 141, and a lower engaging claw portion 141b is provided at the extended edge. The lower engaging claw portion 141b engages with a lower engaging receiving portion 121a provided on the inner lower metal molded body 120A, thereby maintaining a space between the lower inner cover base 141 and the lower inner facing plate portion 121, and covering the facing surface on the inner circumferential side of the lower inner facing plate portion 121.

[0041] The outer lower resin molded body 140B is formed by integrally molding the lower outer cover base 145 and the lower outer rail cover portion 146. The lower outer cover base 145 is a flat plate that covers the lower outer facing plate portion 127 and the bridge material 120C of the metal profile 120. A small gap is maintained between the edge of the lower outer cover base 145 that is located on the indoor side and the facing surface of the lower inner facing plate portion 122 that is facing the outdoors. The lower outer rail cover portion 146 is for forming the resin rail portion of the lower horizontal rail 14A corresponding to the outer sash 20A, and extends inward from the edge of the lower outer cover base 145 that is located on the outdoor side. A lower fitting portion 146a is provided on the edge of the lower outer rail cover portion 146 that is on the inner side. The lower fitting portion 146a extends outward from the extended edge of the lower outer rail cover portion 146, and then bends outward. The lower outer rail cover portion 146 covers the interior-facing surface of the lower outer rail cover portion 128 by fitting the lower fitting portion 146a 146a into the lower fitting portion 128b of the lower outer facing plate portion 128, while maintaining a space between the lower outer facing plate portion 128 and the lower outer facing plate portion 128.

[0042] The outer lower resin molded body 140B is provided with a plurality of engaging protrusions 145a on the outer circumference side of the lower outer cover base 145. The engaging protrusions 145a extend outward from the lower outer cover base 145, and engaging claws 145b are provided on the extended edges. The engaging claws 145b engage with the lower engaging receiving portion 127a provided on the outer lower metal molded body 120B, thereby maintaining a space between the lower outer cover base 145 and the lower outer visible plate portion 127, and covering the visible surface on the inner circumference side of the lower outer visible plate portion 127.

[0043] In the metal profile 120 of the lower frame 14, an outer lower metal cover body 150 is provided in the portion located between the lower windbreak member 110B and the right vertical frame 12, having substantially the same cross-sectional shape as the outer lower resin molded body 140B. That is, the outer lower metal cover body 150 is integrally molded with a lower outer cover base 151, a lower outer rail cover portion 152, a lower fitting portion 152a, and an engaging projection 151a. However, the lower outer cover base 151 of the outer lower metal cover body 150 is configured to be slightly shorter in dimension than the lower outer cover base 145 of the outer lower resin molded body 140B.

[0044] In the joinery configured as described above, the upper frame 13 is made of metal profiles 80 and resin profiles 90, which is advantageous in terms of thermal insulation and eliminates the risk of problems such as condensation. Furthermore, by integrally molding the resin profile 90 of the upper frame 13 from the inner cover portion 97 for the upper outer rail to the inner cover portion 100 for the upper inner rail as an outer upper resin molded body 90B, it is possible to prevent situations where handling becomes complicated or assembly work becomes complicated due to the enlargement of the parts.

[0045] Here, as shown in Figure 2, the inner upper resin molded body 90A of the divided resin profile 90 can be prevented from falling out by screwing a screw S into the frame B via the upper inner cover base 91, and also by screwing a screw into the upper inner facing plate portion 81 of the metal profile 80 via the upper inner cover base 91, although this is not explicitly shown in the figure. Moreover, the screw S screwed into the upper inner cover base 91 is covered by the upper facing cover portion 93 and extension cover portion 95 located on the interior side, making it difficult to easily see, and thus there is no risk of the appearance quality being impaired.

[0046] On the other hand, the outer upper resin molded body 90B is positioned on the outside of the upper fixing face plate portion 87, making it difficult to screw screws into it via the upper outer cover base portion 96. Furthermore, if screws were to be screwed into the upper outer cover base portion 96, it would be easily visible from the inside, which would not be desirable in terms of appearance quality, and there would also be concerns that it could lead to water from outside entering. However, with the above-described joinery, the outer upper resin molded body 90B is provided with a recess 102 for accommodating the upper inner face plate portion 82, and the projecting portion 82e of the upper inner face plate portion 82 and the intermediate engaging portion 100a of the inner cover portion 100 for the upper inner rail engage with each other in the recess 102. Moreover, the inner cover portion 97 for the upper outer rail and the upper outer face plate portion 85 are fitted together by upper fitting portions 97a and 85a. Therefore, even if the sliding doors 20A and 20B move in the projection direction relative to the frame 10 due to the influence of wind pressure, the outer upper resin molded body 90B, which is pressed by the sliding doors 20A and 20B, is less likely to shift position relative to the metal profile 80, thus preventing it from falling off the metal profile 80. In particular, in the above-described joinery, the multiple contact protrusions 82f of the upper inner facing plate portion 82 will contact the inner wall surface of the recess 102. Furthermore, an engaging claw portion 96c is provided on the projection surface on the outer circumference side of the upper outer cover base portion 96 so as to protrude outward, and is designed to engage with the upper engaging receiving portion 84a provided on the upper outer facing plate portion 84. As a result, the displacement of the outer upper resin molded body 90B relative to the metal profile 80 can be prevented more reliably. Furthermore, since the upper outer projection plate portion 84 has a thickened portion 84b along the longitudinal side of the upper frame 13, there is no risk of the resin profile 90 falling off due to deformation of the metal profile 80.

[0047] Furthermore, since the joint 101 between the outer upper resin molded body 90B and the inner upper resin molded body 90A does not exist between the visible surface of the outer upper horizontal rail 13A facing the interior and the visible surface of the inner upper horizontal rail 13B facing the exterior, airtightness between it and the upper windbreak member 110A can be ensured, and there is no concern that outside air or water from outside will enter the interior through the joint 101 of the resin profile 90. In addition, since the position of the joint 101 is on the outer periphery side of the contact position of the tight material 36, the sashes 20A and 20B will not slide while the tight material 36 is in contact with the joint 101, which is advantageous in terms of watertightness and airtightness.

[0048] Furthermore, as described above, the left and right vertical frames 11, 12 and the bottom frame 14 are also constructed from metal profiles 40, 60, 120 and resin profiles 50, 70, 140, respectively, which is advantageous in terms of thermal insulation. In addition, when viewed from the interior side, the metal profile 120 of the bottom frame 14, the metal profiles 40, 60 of the vertical frames 11, 12, and the metal profile 80 of the top frame 13 are all covered with resin profiles 140, 50, 70, 90, and these resin profiles 140, 50, 70, 90 are configured to exhibit the same hue as the frames 22A, 22B, 23A, 23B, 24A, 24B, 25A, 25B of the sashes 20A, 20B. Therefore, it is advantageous in terms of appearance quality when viewed from the interior side.

[0049] In the embodiments described above, the sliding doors 20A and 20B are exemplified by frames 22A, 22B, 23A, 23B, 24A, 24B, 25A, and 25B made of resin. However, the invention is not limited to these, and the sliding doors may, for example, have frames made of a metal such as an aluminum alloy for the exterior side and a resin for the interior side. In addition, the illustrated example shows a mohair-like material as the sealing material 36, but a sealing material made of an elastic material such as rubber may be used, or the sealing material may be made of a soft, fin-shaped member molded integrally with the frame. Furthermore, the upper frame 13 is exemplified by having an inner upper metal molded body 80A and an outer upper metal molded body 80B connected by a bridge material 80C as the metal profile 80, but the metal profile may be integrally molded from metal.

[0050] As described above, the joinery according to the present invention comprises a frame body in which left and right vertical frames, an upper frame, and a lower frame are assembled on all four sides, and an interior sash on the inside and an exterior sash on the outside disposed on the frame body in a state where they slide in the extending direction of the upper frame, wherein the upper frame comprises a metal profile formed from metal and a resin profile formed from resin, and the upper frame is provided with an inner horizontal rail that guides the sliding of the interior sash and an outer horizontal rail that guides the sliding of the exterior sash, and the horizontal rails are provided on the metal profile The upper frame is composed of a metal rail section and a resin rail section provided on the resin profile, and the resin profile of the upper frame includes an outer resin molded body in which the resin rail section of the outer horizontal rail and the portion constituting the resin rail section of the inner horizontal rail are integrally molded, and the outer resin molded body has a recess formed therein for accommodating the metal rail section of the inner horizontal rail, and the metal rail section and the outer resin molded body constituting the recess are provided with engaging portions that engage with each other. Furthermore, in the above-described joinery, the present invention provides that the metal profile of the upper frame has a first metal part that constitutes the metal rail portion of the inner horizontal rail, a second metal part that extends inward from the outer peripheral side of the first metal part, a third metal part that constitutes the metal rail portion of the outer horizontal rail, and a fourth metal part that extends inward from the outer peripheral side of the third metal part and is connected to the outer peripheral side of the first metal part, and the outer resin molded body of the upper frame has a first cover portion that constitutes the resin rail portion of the outer horizontal rail by covering the interior-facing surface of the third metal part, and a second cover portion that covers the fourth metal part by extending inward from the outer peripheral side of the first cover portion. The present invention is characterized in that the following are integrally molded: a part, a third cover part which extends inward from the extended edge of the second cover part and covers the visible surface of the first metal part facing the outside, thereby constituting the resin rail part of the inner horizontal rail, a fourth cover part which extends inward from the edge located on the inner side of the third cover part and covers the surface on the inner side of the first metal part, thereby constituting the resin rail part of the inner horizontal rail, and a fifth cover part which extends outward from the extended edge of the fourth cover part and constitutes the resin rail part of the inner horizontal rail, and which, together with the third cover part and the fourth cover part, constitutes the recess, and the engaging part is provided on the first metal part and the fifth cover part. According to these inventions, by integrally molding the resin rail portion of the outer horizontal rail and the portion constituting the resin rail portion of the inner horizontal rail as an outer resin molded body, it is possible to prevent situations where handling becomes complicated or assembly work becomes complicated due to the enlargement of the parts. Moreover, since the outer resin molded body is provided with a recess for housing the metal rail portion, and the metal rail portion and the outer resin molded body are engaged with each other by an engaging portion in the recess, even if the shoji screen moves in the depth direction relative to the frame due to the influence of wind pressure, the outer resin molded body pressed by the shoji screen is less likely to shift position relative to the metal profile, and the situation of it falling off the metal profile can be prevented.

[0051] Furthermore, in the above-described joinery, the present invention comprises an inner resin molded body in which the resin profile of the upper frame is integrally molded, comprising a sixth cover portion that covers the portion of the first metal part that is on the outer periphery side of the fifth cover portion, and a seventh cover portion that extends from the outer periphery side of the sixth cover portion toward the interior side to cover the second metal part, wherein the inner resin molded body is molded separately from the outer resin molded body. According to this invention, since the resin profile is composed of an outer resin molded body and an inner resin molded body, the increase in the number of parts is minimized, and problems caused by an increase in the number of parts to be handled can be prevented.

[0052] Furthermore, the present invention is characterized in that, in the above-described joinery, the first metal part has a visible extension portion that extends along the third cover portion, a depth extension portion that extends along the fourth cover portion, and a plurality of abutting protrusions that project toward the inner wall surface of the recess. According to this invention, since the multiple contact protrusions of the first metal part contact the inner wall surface of the recess, the misalignment of the outer resin molded body relative to the metal profile is more reliably prevented.

[0053] Furthermore, the present invention is characterized in that, in the above-described joinery, the visible surface on the outer periphery of the second cover portion is provided with an engaging claw portion that protrudes toward the outer periphery, and the fourth metal portion is provided with an engaging receiving portion that engages with the engaging claw portion. According to this invention, by engaging the engaging claw portion with the engaging receiving portion, misalignment of the outer resin molded body relative to the metal profile can be prevented more reliably.

[0054] Furthermore, the present invention is characterized in that, in the above-described joinery, the fourth metal part has a thickened portion with increased plate thickness provided along the longitudinal side of the upper frame. According to this invention, even when the sliding door moves in the depth direction relative to the frame due to the influence of wind pressure, deformation of the metal profile can be more reliably prevented.

[0055] Furthermore, the present invention is characterized in that, in the above-described joinery, the third metal part and the first cover part are provided with an upper fitting part that restricts movement in directions away from each other by fitting together. According to this invention, by fitting the upper fitting portion, misalignment of the outer resin molded body relative to the metal profile can be prevented more reliably. [Explanation of symbols]
