[0009] An embodiment of the door frame and door fitting of the present invention will be described with reference to the drawings. The fitting frame of this embodiment is a long frame component that forms the frame of the fitting. The fitting of this embodiment is equipped with the fitting frame of this embodiment and is installed on the wall of a building. On the wall of the building, the fitting and fitting frame are arranged between the interior (indoors) and exterior (outdoors) of the building.

[0010] (First embodiment) Fig. 1 is a front view showing the fitting 1 of the first embodiment, showing the fitting 1 as seen from inside the room. Fig. 2 is a vertical cross-sectional view showing the fitting 1 of the first embodiment, and Fig. 3 is a horizontal cross-sectional view showing the fitting 1 of the first embodiment. Figs. 2 and 3 show a cross-section of a part of a building 10 in which the fitting 1 is installed.

[0011] As shown in the figure, the fitting 1 is a sliding window installed in a building opening 11. The building opening 11 is an opening formed in a wall of a building 10, and is surrounded by four edges of the building opening 11 (upper edge, lower edge, and a pair of vertical edges). The fitting 1 comprises two sliding shoji screens 2 and 3 (first shoji screen 2 and second shoji screen 3) and a frame 4 surrounding the shoji screens 2 and 3. The first shoji screen 2 is an exterior shoji screen (exterior shoji screen) located on the exterior side of the room, and the second shoji screen 3 is an interior shoji screen (interior shoji screen) located on the interior side of the room. The frame 4 is a rectangular opening frame (window frame) and has multiple fitting frames 5 to 8. The frame 4 and fitting frames 5 to 8 are attached to the edges of the building opening 11 and are installed at the edges of the building opening 11.

[0012] When the fittings 1 and fitting frames 5-8 installed in the building 10 are viewed from the front (see FIG. 1), the up-down direction is the up-down direction, and the left-right direction is the left-right direction. In FIG. 1, the up-down direction is the vertical direction, and the left-right direction is the horizontal direction. The indoor / outdoor direction (see FIGS. 2 and 3) is the indoor / outdoor direction (indoor / outdoor direction) of the fittings 1 and fitting frames 5-8 installed in the building 10. Furthermore, the indoor / outdoor direction is the front-to-back direction (depth direction) when the fittings 1 and fitting frames 5-8 installed in the building 10 are viewed from the front, and in FIG. 1, it is the horizontal direction perpendicular to the left-to-right direction. In this way, the directions related to the fittings 1 and fitting frames 5-8 are specified as directions when they are installed in the building 10. Furthermore, the indoor side and outdoor side of the fittings 1 and fitting frames 5-8 are the indoor side and outdoor side when they are installed in the building 10.

[0013] The shoji screens 2 and 3 are movable sliding screens (panel bodies) that move by sliding, and are arranged so that they can move (slidably) in the opening of the frame body 4 (frame body opening 4A). The shoji screens 2 and 3 slide left and right in the frame body opening 4A in a double sliding manner. The frame body opening 4A is opened and closed by the movement of the shoji screens 2 and 3. When the shoji screens 2 and 3 are closed, they are locked by the locking device 9. The locking device 9 is a crescent that has a crescent lock and a crescent receiver, and is attached to each of the shoji screens 2 and 3.

[0014] The frame body 4 forms a square frame body opening 4A by four fitting frames 5-8 (upper fitting frame 5, lower fitting frame 6, and a pair of vertical fitting frames 7, 8) that are combined with each other. The upper fitting frame 5 and lower fitting frame 6 are horizontal fitting frames on the top and bottom of the frame body 4, and extend in the left-right direction (horizontal direction) at the top and bottom of the frame body 4. The pair of vertical fitting frames 7, 8 (first vertical fitting frame 7, second vertical fitting frame 8) are side frames located on the left and right sides of the frame body 4, and extend in the up-down direction (vertical direction) at the sides of the frame body 4. The fitting frames 5-8 are framed by connecting the ends of the upper fitting frame 5, lower fitting frame 6, and the left and right vertical fitting frames 7, 8.

[0015] The fitting frames 5-8 are fitting frames (composite frames) of a composite structure each having a metal frame portion 5A-8A and a resin frame portion 5B-8B. The metal frame portions 5A-8A and the resin frame portions 5B-8B are each made of shaped members (extruded shaped members) formed by extrusion molding. The metal frame portions 5A-8A are frame members made of metal (for example, aluminum alloy) and are attached to the edge of the building opening 11. The resin frame portions 5B-8B are frame members made of synthetic resin and are attached to the metal frame portions 5A-8A.

[0016] The upper door frame 5 and the lower door frame 6 each have one metal frame portion 5A, 6A and two resin frame portions 5B, 6B, and the first vertical door frame 7 and the second vertical door frame 8 each have one metal frame portion 7A, 8A and one resin frame portion 7B, 8B. The metal frame portions 5A-8A are arranged on the edge of the building opening 11 and extend in the longitudinal direction of the edge of the building opening 11 along the edge of the building opening 11. The resin frame portions 5B-8B are arranged on the frame body opening 4A side (the inner side of the building opening 11) with respect to the metal frame portions 5A-8A and extend in the longitudinal direction of the metal frame portions 5A-8A along the metal frame portions 5A-8A.

[0017] FIG. 4 is a cross section showing the first vertical door frame 7 of the first embodiment, showing a cross section perpendicular to the longitudinal direction of the first vertical door frame 7. As shown in the figure, the direction indicated by arrow R is the front view direction R of the first vertical door frame 7, which is the indoor / outdoor direction in this case. The direction indicated by arrow S is the front view direction S of the first vertical door frame 7, which is the left-right direction in this case. Furthermore, the longitudinal directions of the first vertical door frame 7, the metal frame portion 7A, and the resin frame portion 7B are all the same, which is the up-down direction in this case.

[0018] The metal frame portion 7A of the first vertical door frame 7 has a recessed portion 20 located on the resin frame portion 7B side (frame body opening 4A side), multiple protruding wall portions 21, 22 (first protruding wall portion 21, second protruding wall portion 22) protruding from the recessed portion 20 toward the frame body opening 4A side, multiple engaging portions 23, 24 (first engaging portion 23, second engaging portion 24) that engage with the resin frame portion 7B, and multiple locking protrusions 25 that lock the resin frame portion 7B. The recessed portion 20, the protruding wall portions 21, 22, and the engaging portions 23, 24 each extend in the longitudinal direction of the metal frame portion 7A between one end and the other end of the metal frame portion 7A in the longitudinal direction. The recessed portion 20 of the metal frame portion 7A is arranged along the recessed direction R of the first vertical door frame 7 and faces the resin frame portion 7B in the sight direction S of the first vertical door frame 7.

[0019] The multiple (here, two) protruding wall portions 21, 22 of the metal frame portion 7A are formed spaced apart from each other in the projection direction R of the first vertical door frame 7. The protruding wall portions 21, 22 are located on the exterior side of the resin frame portion 7B, and protrude from the projection portion 20 in the projection direction S of the first vertical door frame 7. The first protruding wall portion 21 is an exterior wall portion located at the exterior end of the metal frame portion 7A, and is located on the exterior side of the second protruding wall portion 22. The second protruding wall portion 22 is a receiving piece that receives the first shoji screen 2 (see Figure 3), and is located on the exterior side of the resin frame portion 7B.

[0020] The engagement portions 23, 24 and the locking protrusion 25 of the metal frame portion 7A are provided in the projection portion 20, are located on the interior side of the room relative to the second protruding wall portion 22, and are covered by the resin frame portion 7B in the viewing direction S of the first vertical door frame 7. The multiple (here, two) engagement portions 23, 24 are formed spaced apart from each other in the viewing direction R of the first vertical door frame 7, and protrude from the projection portion 20 toward the resin frame portion 7B.

[0021] The first engagement portion 23 is an outdoor engagement portion located further outdoors than the second engagement portion 24, and the second engagement portion 24 is an indoor engagement portion located further indoors than the first engagement portion 23. The first engagement portion 23 is an engagement groove portion formed in a groove shape and is open toward the resin frame portion 7B side (frame body opening 4A side). The first engagement portion 23 has a protrusion 23A that protrudes toward the indoor side. The second engagement portion 24 is an engagement protrusion formed in a protruding shape and has a protrusion 24A that protrudes toward the outdoor side.

[0022] The multiple locking protrusions 25 of the metal frame portion 7A are locking portions (protrusions) formed in a protruding shape and are provided spaced apart from one another in the longitudinal direction of the metal frame portion 7A. The locking protrusions 25 are provided at locations near both longitudinal ends of the metal frame portion 7A and at one or more locations between the locking protrusions 25 near the both longitudinal ends. Here, three locking protrusions 25 are provided in the recessed portion 20 of the metal frame portion 7A. The multiple locking protrusions 25 are located between the first engagement portion 23 and the second engagement portion 24 in the recessed direction R of the first vertical door frame 7, and are arranged side by side in the longitudinal direction of the metal frame portion 7A at intervals.

[0023] Each of the multiple locking protrusions 25 is a threaded portion 26A of the screw 26. The threaded portion 26A is a shaft portion (male thread portion) having the threads of the screw 26, and the threads are formed on the outer periphery of the threaded portion 26A. At multiple locations in the longitudinal direction of the metal frame portion 7A, the threaded portions 26A of the screws 26 are inserted from the opposite side of the resin frame portion 7B into screw holes 20A formed in the recessed portion 20 of the metal frame portion 7A and screwed into the screw holes 20A. As a result, the threaded portions 26A and the screws 26 are attached to and fixed to the recessed portion 20. The threaded portions 26A and the locking protrusions 25 protrude from the recessed portion 20 toward the resin frame portion 7B in the sight direction S of the first vertical door frame 7.

[0024] The resin frame portion 7B of the first vertical door frame 7 is located on the indoor side of the second protruding wall portion 22 of the metal frame portion 7A, and covers the portion of the metal frame portion 7A on the frame body opening 4A side that is indoors beyond the second protruding wall portion 22. The resin frame portion 7B has a projection portion 30 located on the frame body opening 4A side, a facing portion 31 located on the metal frame portion 7A side, a protruding wall portion 32 that protrudes from the facing portion 31 toward the metal frame portion 7A, a plurality of engaged portions 33, 34 (first engaged portion 33, second engaged portion 34) that engage with the metal frame portion 7A, and a plurality of engaged portions 35 that engage with the metal frame portion 7A.

[0025] The recessed portion 30, opposing portion 31, protruding wall portion 32, and engaged portions 33 and 34 of the resin frame portion 7B each extend in the longitudinal direction of the resin frame portion 7B between one end and the other end of the resin frame portion 7B in the longitudinal direction. The first engaged portion 33 and protruding wall portion 32 of the resin frame portion 7B come into contact with the recessed portion 20 of the metal frame portion 7A, thereby positioning the resin frame portion 7B in the sight direction S of the first vertical door and window frame 7. This positions the resin frame portion 7B relative to the recessed portion 20 of the metal frame portion 7A.

[0026] The recessed portion 30 of the resin frame portion 7B has an indoor-side recessed portion 30A and an outdoor-side recessed portion 30B, and the facing portion 31 of the resin frame portion 7B has an indoor-side facing portion 31A and an outdoor-side facing portion 31B. The indoor-side recessed portion 30A and the indoor-side facing portion 31A are spaced apart in the sight direction S of the first vertical door frame 7, forming a hollow portion 36 between them. The outdoor-side recessed portion 30B and the outdoor-side facing portion 31B are the same part of the resin frame portion 7B, protrude from the hollow portion 36 toward the outside of the room, and are positioned opposite the second protruding wall portion 22 of the metal frame portion 7A in the sight direction R of the first vertical door frame 7.

[0027] The facing portion 31 of the resin frame portion 7B is disposed opposite the recessed portion 20 of the metal frame portion 7A with a gap therebetween in the sight direction S of the first vertical door frame 7. The protruding wall portion 32, engaged portions 33, 34, and locked portion 35 of the resin frame portion 7B are provided on the facing portion 31, and the protruding wall portion 32 and engaged portions 33, 34 protrude from the facing portion 31 toward the recessed portion 20 of the metal frame portion 7A in the sight direction S of the first vertical door frame 7. The protruding wall portion 32 is an indoor-side wall portion located at the indoor-side end of the resin frame portion 7B, and is located indoors relative to the engaged portions 33, 34 and locked portion 35 of the resin frame portion 7B and the engaging portions 23, 24 and locking protrusion 25 of the metal frame portion 7A.

[0028] The multiple (here, two) engaged portions 33, 34 of the resin frame portion 7B are engaged protrusions formed in a protruding shape and are formed spaced apart from each other in the projection direction R of the first vertical door frame 7. The resin frame portion 7B is attached to the metal frame portion 7A (projection portion 20) with the multiple engaged portions 33, 34 respectively engaged with the corresponding engaging portions 23, 24 of the metal frame portion 7A. The first engaged portion 33 is an outdoor engaged portion located on the outdoor side of the second engaged portion 34 and is bent toward the outdoor side. The second engaged portion 34 is an indoor engaged portion located on the indoor side of the first engaged portion 33 and is bent toward the indoor side.

[0029] The first engaged portion 33 (here, the tip side portion bent toward the outside of the room) of the resin frame portion 7B is disposed in the groove-shaped first engaging portion 23 of the metal frame portion 7A and detachably engages with the first engaging portion 23. The first engaged portion 33 is held in the first engaging portion 23 by being caught on the protruding piece 23A of the first engaging portion 23. The second engaged portion 34 (here, the tip side portion bent toward the inside of the room) of the resin frame portion 7B abuts against the protruding second engaging portion 24 of the metal frame portion 7A from the outside of the room and detachably engages with the second engaging portion 24. The second engaged portion 34 is held in the second engaging portion 24 by being caught on the protruding piece 24A of the second engaging portion 24.

[0030] The resin frame portion 7B has a locking piece 37 that is locked to the multiple locking protrusions 25 of the metal frame portion 7A, and the multiple locking portions 35 are formed on the locking piece 37. The locking piece 37 extends in the longitudinal direction of the resin frame portion 7B between one end and the other end in the longitudinal direction of the resin frame portion 7B. The locking piece 37 is also provided on the facing portion 31 and protrudes from the facing portion 31 toward the recessed portion 20 of the metal frame portion 7A.

[0031] The interlocking piece 37 has a first protruding portion 37A and a second protruding portion 37B formed continuously. The first protruding portion 37A protrudes from the opposing portion 31 toward the recessed portion 20 of the metal frame portion 7A in the sight direction S of the first vertical door frame 7. The second protruding portion 37B protrudes toward the outside of the room from the tip of the first protruding portion 37A in the protruding direction and is arranged along the recessed portion 20 of the metal frame portion 7A. The interlocking piece 37 is formed into a bent shape by the first protruding portion 37A and the second protruding portion 37B, and is bent toward the outside of the room.

[0032] Fig. 5 is a view showing the locking protrusions 25 of the resin frame 7B and metal frame 7A of the first embodiment as viewed from the direction of arrow X in Fig. 4, illustrating one end of the resin frame 7B in the longitudinal direction. Fig. 5 shows a cross section of the locking protrusions 25 (threaded portions 26A). Figs. 5A to 5C also show three examples of the shapes of the locked portions 35 of the resin frame 7B.

[0033] As shown in the figure, the multiple interlocking portions 35 of the resin frame portion 7B are recesses 37C formed at multiple locations on the interlocking pieces 37 (here, the second protrusions 37B) spaced apart from one another in the longitudinal direction of the resin frame portion 7B. The recesses 37C are notches formed by cutting out the interlocking pieces 37, and are formed in a concave shape in the interlocking pieces 37 at multiple locations in the longitudinal direction of the interlocking pieces 37. The recesses 37C penetrate the interlocking pieces 37 in the viewing direction S of the first vertical door frame 7. The recesses 37C are recessed from the exterior end (tip) of the interlocking pieces 37 toward the interior and open toward the exterior. The recesses 37C are formed, for example, in a rectangular shape (see FIG. 5A), a triangular shape (see FIG. 5B), or a U-shape (see FIG. 5C) when viewed from the viewing direction S of the first vertical door frame 7.

[0034] The multiple locked portions 35 (recesses 37C) of the resin frame portion 7B are recessed locking recesses formed in a concave shape and are spaced apart from one another in the longitudinal direction of the resin frame portion 7B. The locked portions 35 are provided at one or more locations near both longitudinal ends of the resin frame portion 7B and between the locked portions 35 near both longitudinal ends. Here, three locked portions 35 are provided on the locked pieces 37 of the resin frame portion 7B. The locked pieces 37 and the locked portions 35 are located between the first engaged portion 33 and the second engaged portion 34 in the projection direction R of the first vertical door / window frame 7, and the multiple locked portions 35 are formed at intervals in the longitudinal direction of the resin frame portion 7B.

[0035] The threaded portion 26A, which is the locking protrusion 25 of the metal frame portion 7A, is positioned within the recessed portion 37C, which is the locked portion 35 of the resin frame portion 7B, and fits into the recessed portion 37C. As a result, the multiple locked portions 35 of the resin frame portion 7B are caught on and locked to the corresponding locking protrusions 25 of the metal frame portion 7A. The locking protrusions 25 are holding portions, and the locked portions 35 are held portions. The locked portions 35 and locked pieces 37 are held by the locking protrusions 25 in the longitudinal direction of the first vertical door frame 7, and the locking protrusions 25 restrict displacement of the first vertical door frame 7 in the longitudinal direction. Furthermore, the locking protrusions 25 restrict displacement of the locked portions 35 and locked pieces 37 to one side (here, the outside of the room) in the projection direction R of the first vertical door frame 7.

[0036] The locking protrusion 25 of the metal frame portion 7A and the locked portion 35 of the resin frame portion 7B are located between the recessed portion 20 of the metal frame portion 7A and the facing portion 31 of the resin frame portion 7B (see FIG. 4). Here, the multiple engaging portions 23, 24 and multiple locking protrusions 25 of the metal frame portion 7A, and the multiple engaged portions 33, 34, locked pieces 37 and multiple locked portions 35 of the resin frame portion 7B are all located between the recessed portion 20 and the facing portion 31 in the viewing direction S of the first vertical door and window frame 7. Between the recessed portion 20 and the facing portion 31, the engaged portions 33, 34 engage with the engaging portions 23, 24, and the locked portion 35 is locked to the locking protrusion 25.

[0037] The locking protrusions 25 of the metal frame portion 7A and the locked portions 35 of the resin frame portion 7B are covered and shielded by the resin frame portion 7B when the first vertical door and window frame 7 is viewed from both the inside and outside of the building 10. Here, the multiple engaging portions 23, 24 and multiple locking protrusions 25 of the metal frame portion 7A, and the multiple engaged portions 33, 34, locked pieces 37, and multiple locked portions 35 of the resin frame portion 7B are all positioned in positions that are shielded by the resin frame portion 7B and the metal frame portion 7A. The engaged portions 33, 34 are shielded by the resin frame portion 7B when engaged with the engaging portions 23, 24, and the locked portion 35 is shielded by the resin frame portion 7B when engaged with the locking protrusions 25.

[0038] When attaching the resin frame portion 7B to the metal frame portion 7A, the resin frame portion 7B is arranged side by side on the longitudinal outside of the metal frame portion 7A without the multiple screws 26 attached to the recessed portions 20 of the metal frame portion 7A (without the multiple locking projections 25 provided on the metal frame portion 7A). Furthermore, on the end face of the metal frame portion 7A, the positions of the engaged portions 33, 34 of the resin frame portion 7B are aligned with the positions of the engaging portions 23, 24 of the metal frame portion 7A. In this state, the resin frame portion 7B is slid along the metal frame portion 7A in the longitudinal direction of the metal frame portion 7A until the resin frame portion 7B is overlapped with the metal frame portion 7A. This engages the engaged portions 33, 34 with the engaging portions 23, 24, and the resin frame portion 7B is attached to the metal frame portion 7A.

[0039] Next, the threaded portions 26A of the multiple screws 26 are screwed into the screw holes 20A of the recessed portions 20 of the metal frame portion 7A to attach the multiple threaded portions 26A to the recessed portions 20. At this time, the threaded portions 26A (locking protrusions 25) are placed in the recessed portions 37C (locked portions 35) of the locked pieces 37 of the resin frame portion 7B to lock the locked portions 35 with the locking protrusions 25. This attaches the resin frame portion 7B to the metal frame portion 7A.

[0040] The threaded portion 26A of the screw 26 is threaded into the screw hole 20A of the recessed portion 20 of the metal frame portion 7A and is inserted through the recessed portion 37C of the locked piece 37 of the resin frame portion 7B. At this time, the threads of the threaded portion 26A are inserted through the recessed portion 37C while forming a thread in the locked piece 37 at the recessed portion 37C. As a result, the threads of the threaded portion 26A bite into the locked piece 37 and the locked portion 35 at the recessed portion 37C and come into contact with the locked piece 37 and the locked portion 35.

[0041] Alternatively, the resin frame portion 7B may be attached to the metal frame portion 7A by pressing it against the recessed portion 20 of the metal frame portion 7A. In this case, with multiple screws 26 attached to the recessed portion 20 of the metal frame portion 7A (with multiple locking protrusions 25 provided on the metal frame portion 7A), the first engaged portion 33 of the resin frame portion 7B is pressed against the first engaging portion 23 of the metal frame portion 7A. Next, the interior-side end of the resin frame portion 7B is moved from a position spaced apart from the recessed portion 20 of the metal frame portion 7A toward the recessed portion 20 of the metal frame portion 7A. As the resin frame portion 7B moves, the resin frame portion 7B is rotated around the first engaged portion 33, and the second engaged portion 34 of the resin frame portion 7B is pressed against the second engaging portion 24 of the metal frame portion 7A.

[0042] By rotating the resin frame portion 7B, the engaged portions 33, 34 engage with the engaging portions 23, 24, and the resin frame portion 7B is attached to the metal frame portion 7A. At the same time, the threaded portion 26A (locking protrusion 25) of the screw 26 is positioned in the recess 37C (locked portion 35) of the engaged piece 37 of the resin frame portion 7B, and the engaged portion 35 is locked with the locking protrusion 25. In this way, the resin frame portion 7B is attached to the metal frame portion 7A. Note that after the engaged portions 33, 34 are engaged with the engaging portions 23, 24, the threaded portion 26A may be attached to the recessed portion 20, and the engaged portion 35 may be locked with the locking protrusion 25.

[0043] Next, we will explain the second vertical door frame 8 of the door 1. Regarding the second vertical door frame 8, the components that correspond to the components of the first vertical door frame 7 will be given the same names as the components of the first vertical door frame 7. Furthermore, regarding the components of the second vertical door frame 8, explanations of the same aspects as the components of the first vertical door frame 7 will be omitted, and the components that differ from the components of the first vertical door frame 7 will be mainly explained. FIG. 6 is a cross section showing the second vertical door frame 8 of the first embodiment, and shows a cross section perpendicular to the longitudinal direction of the second vertical door frame 8.

[0044] As shown in the figure, the metal frame portion 8A of the second vertical door frame 8 has a recessed portion 40, multiple protruding wall portions 41, 42 (first protruding wall portion 41, second protruding wall portion 42), multiple engaging portions 43, 44 (first engaging portion 43, second engaging portion 44), and multiple locking protrusions 45. Of the multiple protruding wall portions 41, 42, the second protruding wall portion 42 is a receiving piece that receives the second shoji screen 3 (see Figure 3). Of the multiple engaging portions 43, 44, the first engaging portion 43 is an engaging protrusion formed in a protruding shape. The first engaging portion 43 has a protruding piece 43A that protrudes toward the inside of the room, and the second engaging portion 44 has a protruding piece 44A that protrudes toward the outside of the room. The multiple locking protrusions 45 are threaded portions 46A of screws 46 that are threaded into the screw holes 40A.

[0045] The resin frame portion 8B of the second vertical door frame 8 has a projection portion 50, an opposing portion 51, a protruding wall portion 52, multiple engaged portions 53, 54 (first engaged portion 53, second engaged portion 54), multiple locked portions 55, and an locked piece 57. The projection portion 50 and the opposing portion 51 are the same part of the resin frame portion 8B, and are arranged along the projection direction R of the second vertical door frame 8, and are arranged opposite the second protruding wall portion 42 of the metal frame portion 8A in the projection direction R of the second vertical door frame 8. The locked piece 57 has a first protruding portion 57A and a second protruding portion 57B.

[0046] Of the multiple engaged portions 53, 54, the first engaged portion 53 is provided on the locked piece 57 (here, the second protruding portion 57B) and is the tip of the locked piece 57. The first engaged portion 53 is arranged on the indoor side of the protruding first engaging portion 43 of the metal frame portion 8A and detachably engages with the first engaging portion 43. The multiple engaged portions 55 of the resin frame portion 8B are recesses 57C formed in multiple locations on the locked piece 57 (here, the first protruding portion 57A and the second protruding portion 57B). The recesses 57C are recessed from the indoor side portion of the locked piece 57 toward the outdoor side and are open toward the indoor side.

[0047] The threaded portion 46A, which is the locking protrusion 45 of the metal frame portion 8A, is positioned within the recessed portion 57C, which is the locked portion 55 of the resin frame portion 8B, and fits into the recessed portion 57C. As a result, the multiple locked portions 55 of the resin frame portion 8B are caught on the corresponding locking protrusions 45 of the metal frame portion 8A and locked to the locking protrusions 45. The locking protrusions 45 restrict the locked portions 55 and the locked pieces 57 from being displaced to one side (here, the room side) in the projection direction R of the first vertical door frame 7. Furthermore, the locked piece 57 (here, the second protrusion 57B) and the first engaged portion 53 of the resin frame portion 8B are positioned between the first engaging portion 43 and the multiple locking protrusions 45 of the metal frame portion 8A in the projection direction R of the second vertical door frame 8. The locked piece 57 and the first engaged portion 53 are sandwiched between the first engaging portion 43 and the plurality of locking protrusions 45 and are held by the first engaging portion 43 and the plurality of locking protrusions 45 .

[0048] In the first embodiment described above, the resin frame portions 7B, 8B of the vertical door and window frames 7, 8 can be easily attached to the metal frame portions 7A, 8A by the engagement of the engaged portions 33, 34, 53, 54 with the engaging portions 23, 24, 43, 44 and the engagement of the locked portions 35, 55 with the locking projections 25, 45. Furthermore, rattle of the resin frame portions 7B, 8B can be suppressed, and the resin frame portions 7B, 8B can be prevented from coming off the metal frame portions 7A, 8A. By engaging the locked portions 35, 55 of the resin frame portions 7B, 8B with the locking projections 25, 45 of the metal frame portions 7A, 8A, the resin frame portions 7B, 8B can be restrained in the longitudinal direction. This allows for easy and reliable regulation of longitudinal expansion and contraction of the resin frame portions 7B, 8B due to temperature changes, and the longitudinal dimensions (lengths) of the resin frame portions 7B, 8B can be maintained.

[0049] The locking protrusions 25, 45 of the metal frame portions 7A, 8A and the locked portions 35, 55 of the resin frame portions 7B, 8B are shielded by the resin frame portions 7B, 8B. Furthermore, the locking protrusions 25, 45 and the locked portions 35, 55 are located between the recessed portions 20, 40 of the metal frame portions 7A, 8A and the opposing portions 31, 51 of the resin frame portions 7B, 8B. Therefore, the resin frame portions 7B, 8B prevent the locking protrusions 25, 45 of the metal frame portions 7A, 8A and the locked portions 35, 55 of the resin frame portions 7B, 8B from being exposed, thereby improving the design of the vertical door and window frames 7, 8.

[0050] The locking protrusions 25, 45 of the metal frame parts 7A, 8A are threaded parts 26A, 46A and are disposed in the recesses 37C, 57C of the locking pieces 37, 57 of the resin frame parts 7B, 8B. Therefore, the locking protrusions 25, 45 can be easily provided on the metal frame parts 7A, 8A, and the locking protrusions 25, 45 can easily hold the resin frame parts 7B, 8B via the locking pieces 37, 57. The threads of the threaded parts 26A, 46A bite into the locking pieces 37, 57 at the locations where the recesses 37C, 57C are formed, so that the locking pieces 37, 57 and the locking parts 35, 55 of the resin frame parts 7B, 8B can be securely held by the locking protrusions 25, 45, preventing rattling of the resin frame parts 7B, 8B.

[0051] In the second vertical door / window frame 8, the first engaged portion 53 of the resin frame portion 8B is provided on the locked piece 57. This allows the locked portion 55 and the first engaged portion 53 of the resin frame portion 8B to be provided on the common locked piece 57, simplifying the structure of the resin frame portion 8B. In addition, the locked piece 57 of the resin frame portion 8B can be firmly held to the metal frame portion 8A by the first engaging portion 43 and the multiple locking protrusions 45 of the metal frame portion 8A.

[0052] The threaded portions 26A, 46A of the locking projections 25, 45 may be in contact with the locking pieces 37, 57 and the locking portions 35, 55 at the locations where the recesses 37C, 57C are formed, or may be disposed within the recesses 37C, 57C without contacting the locking pieces 37, 57 and the locking portions 35, 55. The resin frame portions 7B, 8B may also be bonded to the metal frame portions 7A, 8A. In this case, the locking pieces 37, 57 of the resin frame portions 7B, 8B are bonded to the recessed portions 20, 40 of the metal frame portions 7A, 8A using, for example, double-sided tape or adhesive.

[0053] Next, vertical door frames 7 and 8 of other embodiments will be described. For the vertical door frames 7 and 8 of the second embodiment, explanation of the same matters as those in the vertical door frames 7 and 8 of the first embodiment will be omitted, and the following mainly describes the matters that differ from the vertical door frames 7 and 8 of the first embodiment.
