[0009] [Configuration of this embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 3, an inward-opening window 3 as a fixture according to this embodiment is installed in an opening 5 in a wall panel 10 that is incorporated into a building skeleton 1 and forms part of the wall. The wall panel 10 comprises a panel body 2 and an opening frame 6 that forms the opening 5 in the panel body 2. An exterior wall material 8 is installed on the exterior side of the panel body 2, attached to the building skeleton 1 via a spacer 7. The inward-opening window 3 comprises a window frame 31 (frame body) and a shoji screen 35 arranged within the window frame 31. Partition members 11, 12, and 13 and a drip edge member 14 are attached to the window frame 31 and protrude outside the room as partition members. The trim member 11 is attached to a top frame 32 (described later), and the trim members 12 and 13 are attached to left and right vertical frames 34 (described later). In the following description, the left-right direction of the inward-opening window 3 is referred to as the X-axis direction (width direction), the up-down direction (height direction) of the inward-opening window 3 is referred to as the Y-axis direction, and the projection direction of the inward-opening window 3 is referred to as the Z-axis direction. The X, Y, and Z-axis directions are perpendicular to each other. Furthermore, the outside of the room is one side in the Z-axis direction, and the inside of the room is the other side in the Z-axis direction.
[0010] The panel body 2 comprises a panel frame 23 having upper and lower horizontal members 21 and left and right vertical members 22, and panel members 25 arranged within the panel frame 23. The panel frame 23 is framed horizontally, and the panel members 25 are installed in the space defined by the panel frame 23 above a lintel 61 (described later), and in the space defined below a window sill 62 (described later). Partition posts 26 are provided along the Y-axis direction at intermediate positions in the X-axis direction between the left and right vertical members 22. The panel material 25 includes a bearing surface material 251 as a surface material that constitutes the exterior wall portion of the panel body 2. The bearing surface material 251 is made of particle board or the like made by overlapping a plurality of wooden boards.
[0011] The opening frame 6 comprises upper and lower wooden intermediate horizontal members 60 along the X-axis, which are disposed between the upper and lower horizontal members 21 and connect both ends of the left and right vertical members 22, and left and right wooden intermediate vertical members 65 connected to the upper and lower intermediate horizontal members 60. In this embodiment, the upper intermediate horizontal member 60 is formed as a lintel 61, and the lower intermediate horizontal member 60 is formed as a sill 62. The opening 5 is defined between the left and right vertical members 22 by the lintel 61 and the sill 62. The sill 62 has a step 63 facing the outside of the room, and a lower metal frame member 331 of the lower frame 33 of the inward-opening window 3 (described later) is disposed on the step 63. The lower metal frame member 331 is engaged with and attached to the flashing member 14.
[0012] In the inward-opening window 3, the window frame 31 is arranged along the inner periphery of the opening frame 6, and the shoji screen 35 is arranged within the window frame 31 so as to be able to open inward. The window frame 31 is made up of an upper frame 32 (frame material), a lower frame 33 (frame material), and left and right vertical frames 34 (vertical members), and the lower frame 33 is placed on a window sill 62. The shoji screen 35 is made up of an upper frame 36, a lower frame 37, left and right vertical frames 38, and a surface material 39 such as a glass panel, assembled together.
[0013] In the window frame 31, the left and right vertical frames 34 are formed from the same shape material and are arranged in opposite left-right directions. As shown in Fig. 4, for example, the vertical frames 34 include an aluminum vertical metal frame material 341 (metal frame material) that is arranged in the opening 5 and serves as an outdoor frame material extending in the Y-axis direction, and a resin vertical resin cover material 347 (non-metal frame material) that is connected to the indoor end of the vertical metal frame material 341 and serves as an indoor frame material extending in the Y-axis direction.
[0014] The vertical metal frame material 341 has a vertical visible surface portion 342 along the Z-axis direction, a vertical exterior visible surface portion 343 extending inward from the exterior end of the vertical visible surface portion 342 along the X-axis direction, a vertical interior visible surface portion 344 extending inward from the vertical visible surface portion 342 along the X-axis direction at a position inside the room more than the vertical exterior visible surface portion 343, and a vertical connecting surface portion 345 (connecting surface portion) formed at the interior end of the vertical visible surface portion 342. The vertical visible surface 342 has a hollow portion forming portion 342A that extends inward along the X-axis direction, is bent toward the outside of the room, and is continuous with the vertical exterior visible surface 343. The hollow portion forming portion 342A cooperates with the vertical exterior visible surface 343 to form a hollow portion 342B that extends along the Y-axis direction. Additionally, the hollow portion forming portion 342A and the vertical interior facing surface portion 344 are provided with an airtight material 30 (tight material) that abuts against the vertical frame 38 in the Z-axis direction.
[0015] As shown in Figure 5, the vertical connecting surface portion 345 is configured with a butt portion 51A having an opposing surface portion 511 that faces the butt portion 52A (described later) of the vertical resin cover material 347 in the Z-axis direction, and a protrusion portion 512 that protrudes from the opposing surface portion 511 toward the inside of the room. The facing surface portion 511 extends outward in the X-axis direction at the indoor end of the vertical connecting surface portion 345, forming a flat facing surface along the X and Y axes. In addition, a bent portion 513 bent toward the outside of the room is formed at the outer end of the facing surface portion 511 in the X-axis direction. The protrusion 512 is formed on the opposing surface 511 at a position closer to the inside in the X-axis direction, and the protrusion 512 and the opposing surface 511 form a shoulder 514 on the inside in the X-axis direction. The opposing surface 511 and the protrusion 512 are pressed against a soft portion 522, which will be described later.
[0016] The vertical resin cover material 347 has a vertical resin facing surface 348 along the Z-axis direction and a vertical resin facing surface 349 extending from the indoor end of the vertical resin facing surface 348 to the outer periphery along the X-axis direction, and is formed with an L-shaped cross section. The outdoor end of the vertical resin facing surface 348 is formed with a butt portion 52A that butts against the butt portion 51A of the vertical metal frame material 341 in the Z-axis direction. The butt portion 52A has a bottom portion 521 facing the butt portion 51A in the Z-axis direction, a soft portion 522 protruding from the bottom portion 521 toward the butt portion 51A, and a protruding portion 523 protruding from the bottom portion 521 toward the butt portion 51A and facing the soft portion 522. In this embodiment, the bottom portion 521 is aligned along the X- and Y-axes, the soft portion 522 is positioned inside in the X-axis direction, and the protruding portion 523 is positioned outside in the X-axis direction. The soft portion 522 has a base portion 522A aligned along the X-axis direction and a protruding portion 522B protruding from the base portion 522A toward the exterior in the Z-axis direction, forming an L-shaped cross section. The soft portion 522 is made of a material softer than the other portions of the vertical resin cover member 347 and is formed by two-color molding of the vertical resin cover member 347, forming a part of the vertical resin cover member 347. The protruding portion 523 protrudes toward the exterior in the Z-axis direction along the bent portion 513. The bottom portion 521, soft portion 522, and protruding portion 523 form a recess 53 that opens to the exterior. This vertical resin cover material 347 partially covers the window sill 62 of the wall panel 10 that constitutes part of the building skeleton 1 from the indoor side.
[0017] In the vertical frame 34 described above, the protrusion 512 of the butt joint 51A is disposed in the recess 53 of the butt joint 52A, the tip of the protrusion 512 abuts against the base 522A of the soft part 522, the side of the protrusion 512 abuts against the side of the protrusion 522B of the soft part 522, and the shoulder 514 abuts against the tip of the soft part 522. At this time, the soft part 522 is pressed against the butt joint 51A and undergoes slight elastic deformation, bringing the butt joints 51A and 52A into close contact with each other, thereby maintaining airtightness at the butt joint position of the butt joints 51A and 52A. Furthermore, the protruding portion 523 of the butt portion 52A abuts against the opposing surface portion 511 of the butt portion 51A. In this embodiment, the tip of the protruding portion 523 abuts against the opposing surface portion 511, which facilitates positioning of the vertical resin cover material 347 relative to the vertical metal frame material 341 in the Z-axis direction and maintains an appropriate degree of pressing of the soft portion 522 against the butt portion 51A. Note that the arrangement of the protruding portion 512 in the recessed portion 53 also facilitates positioning of the vertical resin cover material 347 relative to the vertical metal frame material 341.
[0018] In the window frame 31, the upper frame 32 includes, as shown in Figure 6, an aluminum upper metal frame material 311 (metal frame material) as an outdoor frame material that is positioned in the opening 5 and extends in the X-axis direction, and a resin upper resin cover material 317 (non-metal frame material) as an indoor frame material that is connected to the upper metal frame material 311 and extends in the X-axis direction.
[0019] The upper metal frame material 311 has an upper visible surface portion 312 along the Z-axis direction, an upper exterior visible surface portion 313 that is continuous with the exterior end of the upper visible surface portion 312 and is continuous with the Y-axis direction, an upper interior visible surface portion 314 that is continuous with the interior end of the upper visible surface portion 312 and is continuous with the Y-axis direction, and an upper connecting surface portion 315 (connecting surface portion) that is continuous with the outer (upper) end of the upper interior visible surface portion 314 and extends toward the interior along the Z-axis direction. The upper visible surface 312 has a screw hole forming portion 313A formed on its outer circumferential surface (upper surface) to which the vertical frame 34 is screwed, and a hollow portion forming portion 313B is formed at a position opposite to the screw hole forming portion 313A in the Y-axis direction, extending downward from the inner circumferential surface (lower surface) of the upper visible surface 312 and bending toward the outside of the room to be continuous with the upper exterior visible surface 313. The hollow portion forming portion 313B cooperates with the upper exterior visible surface 313 to form a hollow portion 313C along the X-axis direction. Additionally, the upper chamber visible surface portion 314 and the hollow portion forming portion 313B are provided with an airtight material 30 that abuts against the upper frame 36 in the Z-axis direction. The upper exterior sighting surface 313 is formed to extend vertically relative to the upper sighting surface 312. The upper interior sighting surface 314 is formed to extend upward relative to the upper sighting surface 312. The upper connecting surface 315 is formed to extend from the upper end of the upper interior sighting surface 314 toward the interior of the room. This upper metal frame material 311 forms a recess 316 with a generally U-shaped cross section that is defined by an upper visible surface 312, an upper exterior visible surface 313, and an upper interior visible surface 314, and recess 316 is open on the outer periphery (upper side). By forming this recess 316, even if water such as rainwater seeps into the room beyond upper exterior visible surface 313, it is possible to prevent the water from seeping into the room beyond recess 316, and also to promote drainage from recess 316 through vertical frames 34, etc.
[0020] The upper connecting surface 315 is provided with a butt portion 51B that butts against a butt portion 52B (described later) of the upper resin cover material 317 in the Z-axis direction. This butt portion 51B is configured in substantially the same manner as the butt portion 51A described above, and therefore a detailed description thereof will be omitted. The opposing surface of butt portion 51B extends upward in the Y-axis direction, and protrusion 512 is formed at a position closer to the lower side in the Y-axis direction.
[0021] The upper resin cover material 317 has an upper resin facing surface 318 along the Z-axis direction and an upper resin facing surface 319 extending from the indoor end of the upper resin facing surface 318 to the outer periphery (upward) along the Y-axis direction, and is formed with an L-shaped cross section. The outdoor end of the upper resin facing surface 318 is formed with a butt portion 52B that butts against the butt portion 51B of the upper metal frame material 311 in the Z-axis direction. Butt joint 52B is configured in a manner generally similar to butt joint 52A described above, and therefore a detailed description thereof will be omitted. The soft portion of butt joint 52B is disposed on the lower side in the Y-axis direction, and the protruding portion of butt joint 52B is disposed on the upper side in the Y-axis direction. The butt joint position of butt joints 51B and 52B, i.e., the connection position between upper metal frame member 311 and upper resin cover member 317, is located on the indoor side of recess 316. This upper resin cover material 317 partially covers the lintel 61 of the wall panel 10 that constitutes part of the building skeleton 1 from the inside of the room.
[0022] In the above-described upper frame 32, the butt joints 51B, 52B butt against each other in substantially the same manner as the butt joints 51A, 52A of the vertical frame 34, facilitating positioning, ensuring that the soft parts are pressed properly, and maintaining airtightness. For this reason, a detailed description of the butt joints of the butt joints 51B, 52B will be omitted.
[0023] In the window frame 31, the lower frame 33 includes, as shown in Figure 7, an aluminum lower metal frame material 331 (metal frame material) as an outdoor frame material that is arranged in the opening 5 and extends in the X-axis direction, and a resin lower resin cover material 337 (non-metal frame material) as an indoor frame material that is connected to the lower metal frame material 331 and extends in the X-axis direction.
[0024] The lower metal frame material 331 has a hollow rectangular lower frame body 332, a lower exterior appearance surface 333 continuous with the upper exterior end of the lower frame body 332, a lower connecting surface 334 continuous with the lower interior end of the lower frame body 332, and a locking portion 335 continuous with the lower exterior end of the lower frame body 332. A drainage component (drainage valve) 332A is attached to the exterior portion of the lower frame body 332. In addition, the lower frame body 332 is formed with screw hole formation portions 332B into which the vertical frame 34 is screwed. The lower exterior facing surface 333 is aligned along the Y-axis direction. The upper indoor end portions of the lower exterior facing surface 333 and the lower frame body 332 are provided with an airtight material 30 that abuts against the lower frame 37 in the Z-axis direction. The lower connecting surface 334 is formed with a leg piece 336 that rests on a step 63 of the window sill 62. The engaging portion 335 engages with the water flashing material 14 (described later) and is rested on the window sill 62.
[0025] The lower connecting surface 334 is configured with a butt portion 51C that butts against a butt portion 52C (described later) of the lower resin cover material 337 in the Z-axis direction. This butt portion 51C is configured substantially similarly to the butt portion 51A described above, and therefore a detailed description thereof will be omitted. In the butt portion 51C, the opposing surface portion extends upward in the Y-axis direction, the bent portion bent from the opposing surface portion is omitted, and the protrusion portion is formed at a position closer to the upper side in the Y-axis direction.
[0026] In this lower metal frame member 331, the indoor-facing surface and lower connecting surface 334 of the lower frame main body 332 form a drainage groove 330 that is located on the outdoor side of the butt joints 51C, 52C and directly below the water stop line 40 (described later). The groove 330 drains water that has entered the groove 330 to the outdoor side through drainage ports 332C and drainage components 332A formed in the lower frame main body 332.
[0027] The lower resin cover material 337 has a lower resin facing surface 338 along the Z-axis direction and a lower resin facing surface 339 extending from the indoor end of the lower resin facing surface 338 to the outer periphery (downward) along the Y-axis direction, and is formed with an L-shaped cross section. The outdoor end of the lower resin facing surface 338 is formed with a butt portion 52C that butts against the butt portion 51C of the lower metal frame material 331 in the Z-axis direction. The butt portion 52C has a configuration generally similar to the butt portion 52A described above, and therefore a detailed description thereof will be omitted. Note that the soft portion of the butt portion 52C is disposed on the upper side in the Y-axis direction, and the protruding portion of the butt portion 52C is disposed on the lower side in the Y-axis direction. This lower resin cover material 337 partially covers the window sill 62 of the wall panel 10 that constitutes part of the building skeleton 1 from the indoor side.
[0028] In the lower frame 33 described above, the butt joints 51C and 52C butt against each other in a manner similar to the butt joints 51A and 52A of the vertical frame 34, facilitating positioning, ensuring that the soft parts are pressed properly, and maintaining airtightness. For this reason, a detailed description of the butt joints of the butt joints 51B and 52B will be omitted.
[0029] The trim members 11, 12, 13 and the flashing member 14 are made of metal, aluminum in this embodiment, and are framed on all four sides. The trim member 11 and the flashing member 14 are aligned along the X-axis direction, and the trim members 12, 13 are aligned along the Y-axis direction. The trim member 11 is fastened to the upper frame 32 with screws 92 (fixing devices), the trim members 12, 13 are fastened to the left and right vertical frames 34 with screws 92, respectively, and the flashing member 14 is attached by engaging with the lower frame 33. The trim members 11, 12, 13 and the flashing member 14 separate the exterior wall material 8 at a position on the outdoor side of the inward-opening window 3.
[0030] The inward-opening window 3 described above has a frame connection structure 100 that butts and connects the metal frame members 311, 331, and 341 (outdoor frame members) and the resin cover members (non-metal frame members) 317, 337, and 347 (indoor frame members) where they meet. Airtight materials 30 attached to the interior sides of the upper frame 32, lower frame 33, and left and right vertical frames 34 abut against the upper frame 36, lower frame 37, and left and right vertical frames 38 to form a watertight line 40. The butt positions of butt joints 51A, 51B, and 51C and butt joints 52A, 52B, and 52C are located inside the room relative to the watertight line 40. This prevents water from reaching the butt joint from the outside of the room beyond the watertight line 40, eliminating the risk of water leaking outside the frame from the butt joint. Condensation that may occur on the metal frame materials 311, 331, and 341 flows downward and is drained to the outside of the room via a drainage path that passes through various drainage outlets, such as the recessed groove portion 330 formed in the lower metal frame material 331 of the lower frame 33, drainage outlet 332C, and the drainage outlet formed in the groove portion that holds the screen door, as shown in Figure 2.
[0031] [Variations] In the above embodiment, the soft portion 522 is formed at the butt joints 52A, 52B, 52C of the resin cover material (non-metallic frame material) 317, 337, 347, which is the indoor side frame material, but this is not limited to this, and for example, the soft portion 522 may be formed on the metal frame material 311, 331, 341, which is the outdoor side frame material, rather than on the indoor side frame material. In the above embodiment, recesses 53 are formed in the butt joints 52A, 52B, and 52C, but this is not limited thereto, and recesses 53 do not have to be formed as long as the soft portion 522 is configured to be able to closely contact the butt joints 51A, 51B, and 51C. In the above embodiment, protrusions 523 are formed on the butt joints 52A, 52B, and 52C, but if there is no need to position the resin cover material (non-metallic frame material) 317, 337, and 347 relative to the metal frame material 311, 331, and 341 in the Z-axis direction by abutting the protrusions 523 against the butt joints 51A, 51B, and 51C, the configuration of the protrusions 523 may be omitted. In the above embodiment, protrusions 512 are formed on the butt joints 51A, 51B, and 51C, but this is not limited to this. If the soft part 522 can be pressed against the butt joints 51A, 51B, and 51C without the protrusions 512, the configuration of the protrusions 512 may be omitted. In the above embodiment, the lower metal frame material 331 has a drainage groove portion 330 formed at a position inside the room relative to the butt position of the butt portions 51C, 52C, but this is not limited to this, and if drainage is possible without forming the groove portion 330, the configuration of the groove portion 330 may be omitted. In the above embodiment, the outdoor frame material is made up of metal frame material 311, 331, 341 and the indoor frame material is made up of resin cover material (non-metal frame material) 317, 337, 347, but this is not limited to this, and for example, both the outdoor frame material and the indoor frame material may be made up of non-metal frame material such as resin. In the above embodiment, an inward-opening window 3 has been described as the fixture, but other types of windows having a composite frame that connects an exterior frame material and an interior frame material to a frame body may also be used.
[0032] [Summary of the present invention] (1) The frame connection structure of the present invention is a frame connection structure for a fixture having a frame body and a shoji screen, in which the outdoor frame material and the indoor frame material of the frame body are butted together to connect them, and is characterized in that the butt joint of one of the outdoor frame material and the indoor frame material has a soft part formed thereat that abuts against the butt joint of the other frame material, and the butt position of the outdoor frame material and the indoor frame material is positioned inside the room relative to the position of the water stop line formed by the frame body and the shoji screen abutting against each other. According to the frame connection structure of the present invention, the soft portion formed at the butt joint of one frame material is butted against the butt joint of the other frame material and tightly adheres to it, so that airtightness can be maintained at the butt joint between the outdoor frame material and the indoor frame material even when a so-called composite frame is used, which combines an outdoor frame material and an indoor frame material. In addition, since the joint position between the outdoor frame material and the indoor frame material is located inside the room relative to the aforementioned water-stopping line, the risk of rainwater or other water seeping in from the outdoor side to the joint position is reduced. (2) In the frame connection structure of the present invention, the butt joint of one of the frame materials has a bottom portion facing the butt joint of the other frame material, the soft portion, and a protrusion portion that protrudes from the bottom toward the butt joint of the other frame material and faces the soft portion, and the bottom portion, the soft portion, and the protrusion portion may form a recess into which at least a portion of the butt joint of the other frame material engages. With this configuration, at least a portion of the butt joint of the other frame material is engaged with the aforementioned recess, so that the recess can be used to position the outdoor frame material and the indoor frame material relative to each other, making this positioning easy. (3) In the frame connection structure of the present invention, the butt joint portion of the other frame material may have an opposing surface portion facing the butt joint portion of the one frame material, and a protrusion portion protruding from the opposing surface portion and abutting against the soft portion. With this configuration, the aforementioned protrusion abuts against the soft portion, allowing the soft portion to be pressed firmly against the butt joint of the other frame material, thereby more tightly connecting the outdoor frame material and the indoor frame material. (4) In the frame connection structure of the present invention, the butt portion of one of the frame materials has a protruding portion that protrudes toward the butt portion of the other frame material and abuts against the butt portion of the other frame material, and the protruding portion may abut against the butt portion of the other frame material in the forward direction. With this configuration, the outdoor frame material and the indoor frame material can be easily positioned in the projected direction by the abutment of the aforementioned protrusion against the butt joint of the other frame material, and the pressure applied by the soft portion formed at the butt joint of one frame material against the butt joint of the other frame material can be easily set to a predetermined degree. (5) In the frame connection structure of the present invention, the frame body has at least a lower frame formed by connecting the outdoor frame material and the indoor frame material, and the outdoor frame material of the lower frame may have a drainage groove portion formed at a position outside the butt position. This configuration encourages condensation water that may form on the exterior frame material to be drained through the groove, thereby preventing puddles from forming due to condensation.
