[0012] As shown in FIG. 1, the vertical frame 41 is the vertical frame on the suspension side of the opening window portion 1A. The vertical frame 41 is a composite frame member composed of a metal vertical frame member 42 (metal frame member) on the outdoor side and a resin vertical frame member 46 (resin frame member) on the indoor side. The metal vertical frame member 42 is made of metal and is formed by an extruded aluminum member extruded in this embodiment. The vertical resin frame member 46 is made of synthetic resin and is formed by an extruded resin material extruded in this embodiment. The vertical resin frame member 46 covers the indoor exposed surface of the metal vertical frame member 42. Further, a concave groove portion 47 opened to the outdoor side is formed in the vertical resin frame member 46, and a tight material 11 which is an airtight material is attached to the concave groove portion 47.

[0013] The vertical frame 51 is a vertical frame that holds the vertical edge portion of the panel 8 in the fixed window portion 1B. As shown in FIG. 1, the vertical frame 51 is a composite frame member configured by combining an outdoor metal vertical frame member 52 (metal frame member) and an indoor resin vertical frame member 56 (resin frame member). The metal vertical frame member 52 is made of metal and is formed by an extruded aluminum material extruded in this embodiment. The resin vertical frame member 56 is made of synthetic resin and is formed by an extruded resin material extruded in this embodiment. The resin vertical frame member 56 covers the indoor exposed surface of the metal vertical frame member 52. A concave groove portion 57 opened to the outdoor side is formed in the resin vertical frame member 56, and a bead material 12 which is an airtight material is attached to the side wall portion partitioning the concave groove portion 57. Further, the metal vertical frame member 52 is provided with a protruding piece protruding in the X-axis direction from the prospective surface along the Z-axis direction to the outdoor surface of the panel 8, and a bead material 13 which is an airtight material is attached to this protruding piece.

[0014] [Side post] The side post 60 constitutes the vertical frame on the door tip side on the side of the opening window portion 1A and also constitutes the vertical frame that holds one vertical edge portion of the panel 8 on the side of the fixed window portion 1B. As shown in FIGS. 1 and 4, the side post 60 is a composite frame member configured by combining an outdoor metal side post 61 and an indoor resin side post 65 (resin frame member). As shown in FIG. 4, the metal side post 61 is a heat-insulating profile member composed of a metal outdoor member 62, a metal indoor member 63, and a synthetic resin heat-insulating material 64 provided between the outdoor member 62 and the indoor member 63. The heat-insulating material 64 has a function of connecting the outdoor member 62 and the indoor member 63 and blocking heat conduction between the outdoor member 62 and the indoor member 63.

[0015] The outdoor member 62 is formed of an aluminum extrusion profile having a substantially rectangular cross-section, and has an outdoor finding surface 621, an indoor finding surface 622, and finding surfaces 623 and 624, and is formed in a substantially rectangular shape. On the finding surface 624, a protruding piece 625 protruding toward the vertical frame 51 side in the X-axis direction is continuously formed from the finding surface 624. A concave groove portion 626 that opens to the indoor side is formed in the protruding piece 625. A bead material 13, which is an airtight material that abuts against the outdoor surface of the panel 8, is attached to the concave groove portion 626.

[0016] The indoor member 63 includes an outdoor finding surface 631 that partitions a hollow portion, an indoor finding surface 632, and finding surfaces 633 and 634. Here, in the metal upright 61, the first finding surface facing the finding surface (side surface) of the shoji 7, which is the first panel body, includes the finding surface 623 of the outdoor member 62, the finding surface 633 of the indoor member 63, and a heat insulating material 64 disposed between the finding surface 623 and the finding surface 633. In the metal upright 61, the second finding surface facing the finding surface (side surface) of the panel 8, which is the second panel body, includes the finding surface 624 of the outdoor member 62, the finding surface 634 of the indoor member 63, and a heat insulating material 64 disposed between the finding surface 624 and the finding surface 634. At the indoor side end of the finding surface 633, which is the first finding surface, a protruding piece 635 protruding toward the vertical frame 41 side in the X-axis direction is continuously formed from the finding surface 633, and an engaging claw portion 635A protruding to the outdoor side is formed in the protruding piece 635. The formation position of the finding surface 634 in the finding direction (X-axis direction) is on the finding surface 633 side rather than the end on the vertical frame 51 side of the finding surface 631. For this reason, a stepped portion 636 is formed by the portion on the vertical frame 51 side of the finding surface 631 that is closer to the vertical frame 51 than the finding surface 634 and the finding surface 634. The finding surface 634 extends from the finding surface 631 toward the indoor side, is bent toward the vertical frame 51 side in the middle, and further extends toward the indoor side, and the entire flat cross-sectional shape is formed in a crank shape. A regulating portion 637 is formed by the bent portion in the middle of the finding surface 634 in the finding direction.

[0017] At the corner where the expected surface portion 633 and the found surface portion 632 intersect, a screw hole forming portion 638 for forming a screw hole is formed. Also, at the corner where the expected surface portion 634 and the found surface portion 632 intersect, a screw hole forming portion 639 for forming a screw hole is formed. Further, a screw hole forming portion is also formed on the expected surface portion 624 of the outdoor member 62. The outdoor member 62 and the indoor member 63 of the metal upright 61 are connected to the upper frame 21 and the lower frame 31 by screwing screws into the respective screw holes from the upper frame 21 and the lower frame 31. Therefore, even if the heat insulating material 64 softens during a fire, the outdoor member 62 and the indoor member 63 can be maintained in a state of being connected to the upper frame 21 and the lower frame 31, and the fire prevention performance can also be maintained.

[0018] The resin upright 65 includes a covering portion 66 that covers the metal upright 61 from the indoor side, a contact portion 67 that abuts against the outdoor side of the protruding piece 635, and a groove-shaped edge mounting portion 68 to which an edge 90 to be described later is mounted. The covering portion 66 includes a found surface portion 661 along the X-axis direction, a prospective surface portion 662 that is continuous with the end portion of the found surface portion 661 on the side of the vertical frame 41 and extends outward in the Z-axis direction, and two protruding pieces 663 that protrude from the found surface portion 661 toward the found surface portion 632 of the indoor member 63. The contact portion 67 includes a contact piece portion 671 that extends in the X-axis direction from the prospective surface portion 662 toward the prospective surface portion 633, a side wall portion 672 that extends outward in the Z-axis direction from the end portion of the contact piece portion 671 on the side of the vertical frame 41, and further has a tip side protruding toward the prospective surface portion 633 side and is formed in a substantially L-shaped cross-section, and a side wall portion 673 that extends outward in the Z-axis direction from the end portion of the contact piece portion 671 on the side of the metal upright 61, and further has a tip side protruding toward the side wall portion 672 side and is formed in a substantially L-shaped cross-section. Thus, the contact portion 67 has a concave groove portion 674 defined by the contact piece portion 671, the side wall portions 672, 673. The contact piece portion 671 is arranged such that the protruding piece 635 of the metal upright 61 overlaps the indoor side in the Z-axis direction, and is received in the Z-axis direction by this protruding piece 635. On the contact piece portion 671, an engaged protrusion portion 671A with which the engaging claw portion 635A of the protruding piece 635 is engaged protrudes toward the indoor side. The tight material 11, which is an airtight material, is attached to the concave groove portion 674 of the connection portion 67. Specifically, the tip portions of the side wall portions 672 and 673 extend in a direction approaching each other in the X-axis direction, and the base portion 11A of the tight material 11 is fitted between the tip portions of the side wall portions 672 and 673. For this reason, the airtight material attachment portion is constituted by the concave groove portion 674.

[0019] The edge pressing attachment portion 68 includes a fixed piece portion 681 extending outward in the Z-axis direction to the outdoor side from the end portion on the vertical frame 51 side of the finding surface portion 661, a side wall portion 682 extending to the vertical frame 51 side in the X-axis direction from the indoor side end portion of the fixed piece portion 681 and having its tip side protruding to the outdoor side, and a side wall portion 683 extending to the vertical frame 51 side in the X-axis direction from the outdoor side end portion of the fixed piece portion 681 and having its tip side protruding to the indoor side. Thus, the edge pressing attachment portion 68 has a concave groove portion 684 defined by the fixed piece portion 681, the side wall portions 682, and 683. The fixed piece portion 681 is arranged along the prospective surface portion 634 and abuts against the prospective surface portion 634. An engaging portion 681A that engages with the restricting portion 637 of the prospective surface portion 634 protrudes from the fixed piece portion 681. Also, the side wall portion 683 abuts against the stepped portion 636 of the finding surface portion 631.

[0020] A plurality of through holes through which the screw 16 for fixing the fixed piece portion 681 is inserted are formed at a plurality of positions in the vertical direction in the fixed piece portion 681. The screw 16 is a tapping screw and is screwed into the prospective surface portion 634 through the through hole of the fixed piece portion 681. In the prospective surface portion 634, a plurality of pilot holes processed in accordance with the position of the screw hole forming portion 639 are formed at a plurality of positions in the vertical direction in the prospective direction. By screwing the screw 16 from the through hole of the fixed piece portion 681 into the pilot hole, the screw 16 is screwed into the screw hole forming portion 639 by self-tapping, and the fixed piece portion 681 is fixed to the prospective surface portion 634 by this screw 16. In the state where the fixing piece portion 681 abuts against the prospective surface portion 634 and is fixed with the screw 16, the prospective surfaces 682A and 683A, which are the tips of the side wall portions 682 and 683, that is, the inner peripheral side edges, are flush with the prospective surfaces 62A, 63A, and 64A on the vertical frame 51 side of the outdoor member 62, the indoor member 63, and the heat insulating material 64. On the prospective surfaces 62A, 63A, and 64A, a setting block 9 that faces the end surface of the panel 8 and prevents the end surface of the panel 8 from colliding with the metal upright 61 during transportation of the window unit 1 or the like is adhered with a double-sided tape or the like. Here, the second prospective surface portion of the metal upright 61 includes an indoor-side prospective surface formed by the prospective surface portion 634 where the restricting portion 637 is formed, and an outdoor-side prospective surface formed by the prospective surfaces 62A, 63A, and 64A. The outdoor-side prospective surface is formed at a position in the finding direction on the panel 8 side, that is, the vertical frame 51 side, rather than the indoor-side prospective surface. Further, the edge pressing mounting portion 68 is formed such that the prospective surfaces 682A and 683A, which are the inner peripheral side edges, do not protrude toward the inner peripheral side of the frame body, that is, the vertical frame 51 side, from the outdoor-side prospective surfaces 62A, 63A, and 64A.

[0021] An edge pressing portion 90 for holding the panel 8 is mounted on the edge pressing mounting portion 68. The edge pressing portion 90 includes a claw portion 91 that engages with the side wall portion 682, a claw portion 92 that engages with the side wall portion 683, and a prospective surface portion 93 on which the bead material 12 is mounted. The resin upright 65 covers the indoor side of the metal upright 61, and the tight material 11 that abuts against the shoji 7 and the bead material 12 that abuts against the panel 8 are arranged on both the left and right sides of the resin upright 65. Therefore, in the state where the shoji 7 is closed, it is possible to prevent outside air from flowing into the room. Further, the metal upright 61 has the heat insulating material 64 interposed therebetween, which can improve the heat insulating property. Furthermore, the indoor surface of the metal upright 61 is covered with the resin upright 65, so that the metal upright 61 is not exposed to the indoor space, and thus the heat insulating performance of the upright 60 can be further improved.

[0022] [Sash window portion] As described above, the sash window portion 1A of the window unit 1 is configured such that the frame body of the sash window portion 1A is formed by the upper frame 21, the lower frame 31, the vertical frame 41, and the upright 60 (vertical frame), and the shoji 7 is disposed in this frame body so as to be openable and closable. The upper frame 71, lower frame 72, and left and right vertical frames 73, 74 of the shoji 7 are composite frames formed by combining a metal frame material 70A on the outdoor side and a resin frame material 70B on the indoor side. The vertical frame 73 constitutes the vertical frame on the hanging side, and the vertical frame 74 constitutes the vertical frame on the door end side. The vertical frame 73 constitutes the vertical frame on the hanging side, and as shown in FIG. 1, it is rotatably connected to the vertical frame 41 via a hinge 5 attached to the prospective surface portion of the metal vertical frame material 42, enabling the shoji 7 to be opened and closed to the outdoor side by this rotation. In the closed state of this opening window portion 1A, the indoor surface of each resin frame material 70B abuts against the tight material 11 attached to each frame material, thereby forming a tight line in the opening window portion 1A. Also, in the open state, the frame body 75 is separated from the frame body, opening the opening partitioned by the frame body.

[0023] [Fixed window portion] The fixed window portion 1B of the window unit 1 is configured such that the frame body of the fixed window portion 1B is formed by the upper frame 21, lower frame 31, vertical frame 51, and mullion 60 as described above, and a panel 8 is fixed within this frame body. An upper sleeve frame 82 for holding the upper part of the facing material 81 is attached to the upper frame 21, and a lower sleeve frame 83 for holding the lower part of the facing material 81 is attached to the lower frame 31. The upper sleeve frame 82 and the lower sleeve frame 83 are each constituted by combining a metal sleeve frame material 801, 802 on the outdoor side and a resin sleeve frame material 803, 804 on the indoor side. The metal sleeve frame materials 801, 802 are fixedly engaged with the upper frame 21 and the lower frame 31, and the resin sleeve frame materials 803, 804 are engaged with the indoor side portions of the metal sleeve frame materials 801, 802. Further, presser portions 801A and 802A for pressing the facing material 81 from the outdoor side are formed on the metal sleeve frame members 801 and 802. Bead members 13 are respectively fitted and attached to the presser portions 801A and 802A, and by the bead members 13 abutting against the outdoor surface of the facing material 81, the facing material 81 is pressed from the outdoor side. Receiving portions 803A and 804A for receiving the facing material 81 from the indoor side are formed on the resin sleeve frame members 803 and 804. Bead members 12 are respectively hung and attached to the receiving portions 803A and 804A, and by the bead members 12 abutting against the outdoor surface of the facing material 81, the facing material 81 is received from the indoor side.

[0024] [Assembly procedure of the upright] Next, the procedure for assembling the upright 60 by attaching the resin upright 65 to the metal upright 61 will be described with reference to FIGS. 5 to 7. First, as shown in FIG. 5(A), the resin upright 65 is tilted with respect to the metal upright 61, and the contact piece portion 671 is disposed and brought into contact with the outdoor side of the protruding piece 635 of the metal upright 61. Then, while bringing the engaging portion 681A and the fixing piece portion 681 into contact with the looking-in surface portion 634, the edge-pressing mounting portion 68 is moved to the outdoor side to rotate the resin upright 65. As shown in FIG. 5(B), when the resin upright 65 is rotated by moving the edge-pressing mounting portion 68 side to the outdoor side with the contact piece portion 671 in contact with the protruding piece 635 as a fulcrum, the engaged protrusion 671A engages with the engaging claw portion 635A, and when the resin upright 65 rotates, the contact piece portion 671 is maintained in a state of engaging with the protruding piece 635 and can maintain the function of the fulcrum. Then, due to the rotation of the resin upright 65, the engaging portion 681A of the fixing piece portion 681 moves to a position where it engages with the regulating portion 637, and the side wall portion 683 abuts against the stepped portion 636.

[0025] As shown in FIG. 6(A), by engaging the engaging portion 681A with the regulating portion 637 and the side wall portion 683 abutting against the stepped portion 636 of the looking-in surface portion 631, the resin upright 65 is temporarily fixed to the metal upright 61. Next, a screw 16 is inserted from the through hole of the fixing piece portion 681 into the lower hole of the looking-in surface portion 634, and the screw 16 is screwed into the screw hole forming portion 639 by a self-tapping method. The number of screws 16 may be appropriately set according to the height dimension of the upright 60. As a result, as shown in FIG. 6(B), the resin upright 65 is firmly fixed to the metal upright 61 with screws 16. Next, the setting block 9 is attached to the inner peripheral surface of the metal upright 61 with a double-sided tape or the like, and the panel 8 is placed inside the frame of the fixed window portion 1B. At this time, the prospective surfaces 682A and 683A, which are the inner peripheral surfaces of the edge mounting portion 68, do not protrude to the inner peripheral side of the frame more than the prospective surfaces 62A, 63A, and 64A, which are the inner peripheral surfaces of the metal upright 61. Therefore, the panel 8 can be easily placed inside the frame.

[0026] Next, as shown in FIGS. 7(A) and 7(B), the claw portions 91 and 92 of the edge 90 are inserted into the edge mounting portion 68 and engaged with the side wall portions 682 and 683, and the edge 90 is attached to the edge mounting portion 68 by snap fit. As a result, the panel 8 is held between the bead material 13 provided on the protruding piece 625 and the bead material 12 provided on the edge 90. Also, the screw 16 can be hidden by the edge 90, and the internal design property of the window unit 1 as a fitting can be improved.

[0027] According to the window unit 1 as a fitting of the present embodiment, the resin upright 65 abuts on the protruding piece 635 outside the room of the protruding piece 635 of the metal upright 61 with the abutting portion 67 provided on one side in the left-right direction, and with this abutting portion 67 as a fulcrum, the edge mounting portion 68 provided on the other end side in the left-right direction is rotated to the outside of the room, and the engaging portion 681A is engaged with the restricting portion 637, so that it can be attached to the metal upright 61. For this reason, for example, compared with the case where the resin upright is slid from the end of the metal upright 61 in the longitudinal direction and the uprights are assembled, the uprights 60 can be assembled with better workability, simply, and in a short time. Also, since the resin upright 65 is composed of an integral resin profile and is not composed of a plurality of resin profiles as in the prior art, the manufacturing cost of the resin upright 65 can also be reduced. Since one of the abutting portions 67 in the left-right direction of the resin upright 65 abuts on the protruding piece 635, only the fixed piece portion 681 of the edge mounting portion 68 on the other side in the left-right direction needs to be fixed to the metal upright 61 with the screw 16. For this reason, compared with the case of fixing the resin upright with screws to the prospective surfaces on the left and right of the metal upright as in the prior art, the number of fixing points with the screw 16 can be reduced, and the workability of fixing the screw 16 can also be improved. Furthermore, since the engaging portion 681A is engaged with the restricting portion 637, the resin upright 65 can be temporarily fixed to the metal upright 61 before fixing the screw 16. Therefore, the screwing operation of the screw 16 can be easily performed, and the assembly workability can be improved.

[0028] [Modification Example] The metal upright of the upright 60 is not limited to the configuration of the above embodiment. For example, the entire metal upright may be composed of only an aluminum extrusion molding, or a resin liner may be disposed between the outdoor member and the indoor member made of metal, and the outdoor member and the indoor member may be fixed with screws. The resin upright 65 has formed a concave groove portion 674, which is an airtight material mounting portion, at the contact portion 67. However, the contact portion that contacts the protruding piece 635 and the airtight material mounting portion may be configured separately. The edge mounting portion 68 of the resin upright 65 may protrude to the inner peripheral side of the frame body from the prospective surfaces 62A, 63A, and 64A, which are the prospective surfaces on the outdoor side of the metal upright 61, at the inner peripheral side edge. The resin upright 65 is fixed to the metal upright 61 by engaging the engaging portion 681A with the restricting portion 637, and is further firmly fixed to the metal upright 61 with the screw 16. However, it may be fixed to the metal upright 61 only by engagement without using the screw 16. Further, a thick portion may be formed on the metal upright 61, and the screw 16 may be screwed into this thick portion to fix the resin upright 65 to the metal upright 61. Further, the screw 16 for fixing the resin upright is not limited to being disposed at a position hidden by the edge 90. In the above embodiment, the window unit 1 with a single-sleeve opening window is configured as a fitting. However, in addition, various windows with both sleeves may be used, and any window with an upright may be used. As the various windows, a window in which both the first panel body and the second panel body arranged with the upright in between are openable and closable may be used, or both panel bodies may be fixed windows that cannot be opened and closed. Further, not limited to windows, for example, various doors having an upright such as a single-sleeve type or a double-sleeve type may be used. The door may be an entrance door or a sliding door with a flush structure or the like.

[0029] [Summary of the Invention] The present invention relates to a fitting including an upper frame, a lower frame, left and right vertical frames, and a frame body including uprights, and a first panel body and a second panel body disposed in the frame body with the uprights interposed therebetween. The uprights are configured by combining a metal upright on the outdoor side and a resin upright on the indoor side. The metal upright includes a first projected surface portion and a second projected surface portion, a projecting piece projecting from the first projected surface portion, and a restricting portion formed on the second projected surface portion. The resin upright includes a contact portion that abuts on the outdoor side of the projecting piece, an engaging portion that engages with the restricting portion, and a covering portion that is continuously formed from the contact portion to the restricting portion and covers the metal upright from the indoor side. The engaging portion engages with the restricting portion by bringing the contact portion into contact with the outdoor side of the projecting piece and rotating the resin upright with respect to the metal upright. According to the fitting of the present invention, the resin upright can be attached to the metal upright by bringing the contact portion of the resin upright into contact with the outdoor side of the projecting piece of the metal upright and rotating the engaging portion side provided on the opposite side via the covering portion with respect to the contact portion toward the restricting portion side of the metal upright. Therefore, the uprights composed of the metal upright and the resin upright can be easily assembled, and thereby the assembly time of the fitting having the uprights can be shortened. Further, since it is not necessary to configure the resin upright with a plurality of parts, the number of parts constituting the uprights can be reduced and the cost can be reduced.

[0030] In the fitting of the present invention, the first panel body is a shoji configured to be openable and closable with respect to the frame body, and it is preferable that an airtight material mounting portion for mounting an airtight material that abuts on the shoji is formed on the contact portion of the resin upright. According to such a configuration, since the airtight material mounting portion for mounting the airtight material that abuts on the shoji is formed on the contact portion provided for attaching the resin upright to the metal upright, the configuration of the resin upright can be simplified and the cost can be reduced as compared with the case where the contact portion and the airtight material mounting portion are provided separately.

[0031] In the fitting of the present invention, the second panel body is a panel fixed to the frame body, the second projected surface portion includes an indoor projected surface on which the restricting portion is formed, and an outdoor projected surface that is on the outdoor side of the indoor projected surface and has a position in the finding direction on the panel side. The resin upright is arranged along the indoor projected surface and has an edge mounting portion to which an edge for holding the panel is attached. It is preferable that the inner peripheral side edge of the edge mounting portion is formed so as not to protrude to the inner peripheral side of the outdoor projected surface. According to such a configuration, since the inner peripheral side edge of the edge mounting portion to which the edge is attached in the resin upright does not protrude to the inner peripheral side of the outdoor projected surface of the metal upright, the panel can be easily mounted inside the frame before attaching the edge.

[0032] In the fitting of the present invention, the metal upright may include a metal outdoor member, a metal indoor member, and a heat insulating material provided between the outdoor member and the indoor member. According to such a configuration, since the heat insulating material is arranged between the metal outdoor member and the metal indoor member, the heat insulation performance of the metal upright can be improved.

[0033] In the fitting of the present invention, the indoor member has the first projected surface portion and the second projected surface portion, the second projected surface portion has a screw hole forming portion for forming screw holes used for screw fixing to the upper frame and the lower frame, and it is preferable that the resin upright is fixed to the second projected surface portion with screws screwed into the screw hole forming portion. According to such a configuration, since the resin upright is fixed to the indoor member of the metal upright with screws, the resin upright can be firmly fixed to the metal upright. In particular, in the metal indoor member, since screws are screwed into the screw hole forming portion for forming screw holes used for connecting the upper and lower frames, the fixing strength of the screws can also be improved. Furthermore, since the metal indoor member is formed with a screw hole forming portion, even if the heat insulating material softens during a fire, the metal indoor member can be maintained in a state of being connected to the upper frame and the lower frame, and the fire prevention performance can also be maintained.

[0034] In the fitting of the present invention, the second panel body is a panel fixed to the frame body, the resin upright is arranged along the second projected surface portion, and has an edge mounting portion to which an edge for holding the panel is attached. The resin upright is fixed to the metal upright with a screw screwed to the second projected surface portion via the edge mounting portion. It is preferable that the screw is hidden by the edge attached to the edge mounting portion. According to such a configuration, by attaching the edge to the edge mounting portion, the screw for fixing the resin upright to the metal upright can be hidden, and the internal appearance design of the fitting can be improved.
