[Modes for carrying out the invention]

[0009] The embodiments of the building components according to the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to these embodiments.

[0010] In the following, for convenience, the terms "depth direction" and "face direction" may be used. The depth direction (indicated by arrow Z in the diagram) is the direction of interior and exterior along the depth of the joinery. Surfaces and walls along the depth direction may be called the depth surface and depth wall. The face direction is the direction along the vertical direction perpendicular to the depth direction (indicated by arrow Y in the diagram) for elements that extend horizontally, such as top frames, bottom frames, top stiles, and bottom stiles. For elements that extend vertically, such as vertical frames and vertical stiles, it is the direction along the horizontal direction perpendicular to the depth direction (indicated by arrow X in the diagram). Surfaces and walls along the face direction may be called the face surface and face wall.

[0011] Figure 1 is a view of the interior side of the joinery 10 according to an embodiment of the present invention. Figure 2 is a vertical cross-sectional view of the joinery 10. Figure 3 is a horizontal cross-sectional view of the joinery 10. The joinery 10 is a vertical sliding window, which holds a sash 14 on the inner circumference side of the frame 12 and opens by sliding the sash 14 outwards along a rail. The joinery 10 is applied to buildings such as office buildings.

[0012] The shoji screen 14 is constructed by arranging a panel 24 inside a frame body 22, which is formed by assembling a lower frame 16, an upper frame 18, and left and right vertical frames 20 around the perimeter. The frame body 12 is constructed by assembling a lower frame 26, an upper frame 28, and left and right vertical frames 30 around the perimeter. Each frame material and each frame material is a composite material made by combining extruded profiles of metal such as aluminum alloy and resin materials, and each is constructed to have a substantially uniform cross-sectional shape along its entire length.

[0013] The lower frame 26 is a combination of a metal lower frame 32 that mainly constitutes the outer perimeter and exterior side and a resin lower frame 34 that mainly constitutes the inner perimeter and interior side. The resin lower frame 34 may also constitute part of the floor surface. The upper frame 28 is a combination of a metal upper frame 36 that mainly constitutes the outer perimeter and exterior side and a resin upper frame 38 that mainly constitutes the inner perimeter and interior side. The left and right vertical frames 30 are basically symmetrical in structure. The vertical frames 30 are a combination of a metal vertical frame 40 that mainly constitutes the outer perimeter and exterior side and a resin vertical frame 42 that mainly constitutes the inner perimeter and interior side. In this way, the frame body 12 is a metal-resin composite window frame. A hollow space is provided between each metal frame and each resin frame for heat insulation. Each resin frame functions as a decorative frame. In this embodiment, the metal upper frame 36 and the metal vertical frame 40 have the same shape except for details such as screw holes and some dimensions. In this embodiment, the resin upper frame 38 and the resin vertical frame 42 have the same shape except for the visible dimensions. The depth dimensions of each resin frame are the same.

[0014] The bottom frame 16 and the top frame 18 have a basically vertically symmetrical structure. The left and right vertical frames 20 have a basically left-right symmetrical structure. Seals 44 are provided in the gaps in the depth direction between the bottom frame 16 and the bottom frame 26, between the top frame 18 and the top frame 28, and between the vertical frame 20 and the vertical frame 30. Friction stays 46 for the sliding function are provided in the gaps in the visibility direction between the bottom frame 16 and the bottom frame 26, and between the top frame 18 and the top frame 28. The friction stays 46 are link mechanisms that perform the opening and closing operation of the sash 14 relative to the frame 12. A pull-in member 47 is provided between the left vertical frame 20 and the vertical frame 30 in Figure 3. Since the vertical sliding window is not directly connected by hinges, when closed, the tilt is used to pull the sash towards the room by the pull-in member 47. In Figure 3, a handle 50 is provided on the right-hand vertical frame 20, which engages with and disengages from the latch member of the vertical frame 30 to open and close the sash 14. In this embodiment, the panel 24 is made of double-glazed glass.

[0015] The lower frame 16 has a metal frame 52 and a pressing edge 54. Among these, the pressing edge 54 is composed of a metal pressing edge 54a and a resin pressing edge 54b, and the lower frame 16 is a metal-resin composite frame. The metal frame 52 has three hollow parts arranged in the prospecting direction, and on the outdoor side, an inner peripheral side outdoor finding piece 52a protruding toward the inner peripheral side and an outer peripheral side outdoor finding piece 52b protruding toward the outer peripheral side are provided. The metal pressing edge 54a and the resin pressing edge 54b are engaged with each other. The metal pressing edge 54a is plate-shaped and its tip is engaged with the middle part of the metal frame 52. The resin pressing edge 54b is substantially square with two hollow parts and is engaged with the outdoor side end of the metal frame 52. The inner peripheral side outdoor finding piece 52a and the resin pressing edge 54b protrude toward the inner peripheral side and hold the edge of the panel 24 via seals 56 respectively. A backup material is provided on the seal 56. Note that the upper frame 18 and the vertical frame 20 have the same configuration as the lower frame 16 or a configuration with some different shapes and dimensions, and detailed descriptions thereof are omitted.

[0016] The metal upper frame 36 is slightly long in the prospecting direction. The resin upper frame 38 protrudes from the indoor side end of the metal upper frame 36 toward the inner peripheral side, and the whole upper frame 28 is substantially L-shaped. Seals 44 are provided between the resin upper frame 38 and the metal frame 52, and between the metal upper frame 36 and the outer peripheral side outdoor finding piece 52b. A friction stay 46 is provided in the finding direction gap between the metal upper frame 36 and the metal frame 52.

[0017] The metal lower frame 32 has a flat hollow part 32a, an outdoor side prospecting wall 32b, an outdoor side hollow part 32c, a middle finding wall 32d, an indoor side prospecting wall 32e, and an indoor side finding wall 32f. The flat hollow part 32a is elongated in the prospecting direction. The outdoor side prospecting wall 32b protrudes from the lower end of the flat hollow part 32a while being slightly inclined toward the outdoor side. The flat hollow part 32a and the outdoor side prospecting wall 32b face the lower surface of the metal frame 52, and a friction stay 46 is provided in the finding direction gap between the flat hollow part 32a and the metal frame 52. The outdoor side hollow part 32c is a small hollow part at the outdoor side end, and the outdoor side prospecting wall 32b forms its upper wall.

[0018] The indoor-side end of the flat hollow portion 32a protrudes slightly, and an intermediate locating wall 32d extends upward from the tip thereof. The indoor-side locating wall 32f is on the indoor side of the intermediate locating wall 32d and is located slightly below the center of the intermediate locating wall 32d. The indoor-side projecting wall 32e connects the intermediate locating wall 32d and the indoor-side locating wall 32f to form a substantially H shape. The portion of the intermediate locating wall 32d above the indoor-side projecting wall 32e forms a part of the water-stopping line between the indoor and outdoor sides in the fitting 10, and hereinafter this portion is referred to as the water-stopping locating wall 58.

[0019] A pocket 60 is formed on the outdoor side and a hook 61 is formed on the indoor side at the upper end of the water-stopping locating wall 58. The pocket 60 holds the seal 44 and is formed by a pair of vertically symmetric convex portions 60a. A drain hole 62 is formed at the lower end of the water-stopping locating wall 58. The drain hole 62 is formed near one end or both ends of the metal lower frame 32. A filter (drainage component) 64 is provided in the drain hole 62. The drain hole 62 has a certain size according to the specification of the filter 64. The drain hole 62 will be further described later.

[0020] The resin lower frame 34 has a flat substantially T shape and has a projecting piece 34a and a locating piece 34b protruding downward from the projecting piece 34a. The projecting piece 34a engages with the hook 61 near the outdoor-side end. The tip of the locating piece 34b and the indoor-side locating wall 32f engage with each other. The projecting piece 34a, the locating piece 34b, the water-stopping locating wall 58, the indoor-side projecting wall 32e, and the indoor-side locating wall 32f form a space 66. A shallow recess 34c protruding toward the space 66 is formed in the projecting piece 34a. A hole 34d is formed in the recess 34c. A drain valve 68 is provided in the hole 34d. The condensed water generated on the indoor side of the panel 24 enters the space 66 from the recess 34c through the hole 34d, travels along the indoor-side projecting wall 32e, and is discharged from the drain hole 62. The amount of condensed water is very small.

[0021] The metal vertical frame 40 has a vertical frame hollow section 70 that is long in the depth direction, and a facing piece 72 that protrudes briefly inward from the indoor end of the vertical frame hollow section 70, and a facing piece 74 that protrudes briefly inward. The vertical frame hollow section 70 is rectangular and has an indoor facing wall 70a, an outdoor facing wall 70b, an inner facing wall 70c, and an outer facing wall 70d, and in this embodiment the aspect ratio of Figure 3 is approximately 5:1. The depth dimension of the vertical frame hollow section 70 is slightly larger than the vertical frame 20 which is the metal frame 52 and the trim 54 combined. The visible dimension of the vertical frame hollow section 70 is slightly larger than the filter 64 (see Figure 2). The tip of the facing piece 72 is provided with a pocket 60 and a hook 61, similar to the water-stopping facing wall 58, and a seal 44 is provided in the pocket 60 to seal the space between it and the metal frame 52. The visible piece 72 and the visible wall 70a on the interior side are continuous.

[0022] The resin vertical frame 42 has a hollow section 42a, a projection piece 42b, and a facing piece 42c. The hollow section 42a has an irregular shape formed by the joining of two rectangles. The projection piece 42b protrudes from the inner circumference side of the hollow section 42a toward the exterior side. The facing piece 42c protrudes from the interior side of the hollow section 42a toward the outer circumference side. The projection piece 42b engages with the hook 61. The facing piece 42c engages with the tip 74a of the projection piece 74.

[0023] Figure 4 is a perspective view of the metal vertical frame 40 from a diagonal downward angle. In Figure 4, the dashed lines represent the areas cut from the metal vertical frame 40 as a profile. The hollow section 70, the visible piece 72, and the lower end of the tip section 74a of the vertical frame are cut out. Of these, the lower end 70ca of the inner circumferential wall 70c and the lower end 70da of the outer circumferential wall 70d are shaped to be in near contact with the flattened hollow section 32a of the metal lower frame 32 and the upper surface of the outdoor facade wall 32b, but a portion of the lower end 70da forms a drainage gap 76 (see Figures 5 and 6) between it and the outdoor facade wall 32b. The drainage gap 76 is narrow, allowing a small amount of condensation water from the indoor side to drain, but preventing fluids (water, smoke, etc.) from the outdoor side from flowing in in a specified amount or more in a short time. The drainage gap 76 is sufficiently narrow that there is no need to provide drainage components such as a filter 64, and is at least narrower than the drainage hole 62. The drainage gap 76 is set to allow for a smaller drainage rate per unit time than the drainage hole 62 to which the filter 64 is installed. The drainage gap 76 is particularly small in width in the visible direction, making it inconspicuous.

[0024] The lower end 70aa of the interior facing wall 70a and the lower end 72a of the facing piece 72 are continuous and abut against the upper end 58a of the watertight facing wall 58 (see Figures 5 and 6) without any gaps. In other words, a notch 70ab is formed at the lower end of the interior facing wall 70a of the hollow vertical frame section 70.

[0025] Figure 5 is a partial cross-sectional perspective view of the intersection of the metal vertical frame 40 and the metal lower frame 32, viewed from an oblique outdoor perspective. Figure 6 is a perspective view of the intersection of the metal vertical frame 40 and the metal lower frame 32, viewed from an oblique indoor perspective. Figure 7 is a longitudinal cross-sectional view of the intersection of the metal vertical frame 40 and the metal lower frame 32.

[0026] As described above, the interior facing wall 70a and facing piece 72 are in contact with the upper end 58a of the water-stopping facing wall 58, and thus the interior facing wall 70a and facing piece 72 of the water-stopping facing wall 58 are extension walls. Furthermore, the portion of the end of the water-stopping facing wall 58 that corresponds to the extension wall of the interior facing wall 70a fits into the notch 70ab (see Figure 4) and becomes a vertical frame hollow section supplementary wall 78 (shown by dashed lines in Figure 6) that complements the interior facing wall 70a.

[0027] In other words, the hollow section 70 of the vertical frame has a notch 70ab formed below the interior-side facing wall 70a, but this section is complemented by the metal lower frame 32's supplementary wall 78, so the hollow section 70 of the vertical frame is substantially maintained even below the lower end 70aa. The drainage hole 62 is formed in the supplementary wall 78 of the vertical frame and communicates with the interior of the hollow section 70 of the vertical frame. Therefore, condensation water that enters the space 66 from the hole 34d (see Figure 2) enters the interior of the hollow section 70 of the vertical frame through the drainage hole 62 and is then discharged to the outside through the drainage gap 76 along the inclined surface of the exterior-side facing wall 32b. In other words, the hollow section 70 of the vertical frame can drain water to the outside.

[0028] Since the hollow section 70 of the vertical frame does not communicate with the outside except for a limited number of holes such as the drainage gap 76, the drainage holes 62 and the filter 64 are not substantially exposed to the outside. Furthermore, the walls of the hollow section 70 of the vertical frame, including the supplementary wall 78, are made of metal and are heat-resistant. Therefore, even if the resin lower frame 34 is damaged by heat during a fire, and the filter 64 is also damaged by heat, the drainage holes 62 remain covered by the hollow section 70 of the vertical frame, preventing smoke from entering the interior. Similarly, during heavy rain such as typhoons, rainwater does not enter the interior through the drainage holes 62 and the filter 64. In this way, the joinery 10 according to this embodiment is capable of discharging condensation and other fluids to the outside, and prevents fluids such as smoke and water from entering the interior from the outside.

[0029] Since the drain holes 62 and filter 64 are located within the hollow section 70 of the vertical frame, smoke cannot enter in the event of a fire, and therefore there is no need to provide a thermally expandable member in this section, reducing the number of parts, cost, and assembly time. In this embodiment, a thermally expandable member is not provided within the hollow section 70 of the vertical frame, but there is no need to provide a thermally expandable member in a location that would block the drain holes 62 when heated. The hollow section 70 of the vertical frame is narrow, making it difficult to install a thermally expandable member, but this is not necessary in this embodiment. A thermally expandable member is a non-combustible or flame-retardant fire-resistant member that expands with heat, such as a heat-expandable material like graphite that foams when heated.

[0030] The filter 64 is designed to be attached to and detached from the drain hole 62 from the indoor side. As shown in Figure 7, there is a small flange 64a on the indoor side that contacts the watertight wall 58 for stability. The filter 64 can be attached and detached by removing the resin lower frame 34, exposing it to the indoor side, making maintenance easy. The drain hole 62 may be provided with other drainage components such as a check valve instead of the filter 64. Depending on the specifications, the drain hole 62 may be made smaller without providing any drainage components.

[0031] Figure 8 is a schematic cross-sectional view of the area surrounding the drain hole 62, where (a) is a cross-sectional view of the metal lower frame 32 and the metal vertical frame 40, (b) is a cross-sectional view of the metal lower frame 32A and the metal vertical frame 40A according to the first modified example, and (c) is a cross-sectional view of the metal lower frame 32B and the metal vertical frame 40 according to the second modified example.

[0032] As shown in Figure 8(a), the end of the metal lower frame 32 abuts against the outer peripheral wall of the metal vertical frame 40, that is, the surface where the hollow portion 70 of the vertical frame and the visible piece 74 are continuous, and the end of the inner peripheral wall 70c of the metal vertical frame 40 abuts against the outdoor surface of the watertight visible wall 58, thereby forming the hollow portion 70 of the vertical frame.

[0033] As shown in Figure 8(b), the inner periphery-side facing wall 70c and the outer periphery-side facing wall 70d of the metal vertical frame 40A abut against the outdoor-side facing surface of the watertight facing wall 58 of the metal lower frame 32A, thereby forming the hollow portion 70 of the vertical frame.

[0034] As shown in Figure 8(c), a small protrusion 70e protrudes inward from the outer peripheral wall of the metal vertical frame 40B, that is, from the portion where the hollow section 70 of the vertical frame and the visible piece 74 are continuous. The watertight facing wall 58 of the metal lower frame 32B and the protrusion 70e come into contact to form the hollow section 70 of the vertical frame. Thus, the vertical frame hollow section supplementary wall 78 that complements the indoor facing wall 70a can take various forms.

[0035] In this embodiment, a notch 70ab formed in the interior facing wall 70a is closed by a vertical frame hollow section supplementing wall 78 to form a part of the vertical frame hollow section 70, and a drain hole 62 is provided in the vertical frame hollow section supplementing wall 78. However, the vertical frame hollow section supplementing wall 78 may also be the exterior facing wall 70b that supplements the vertical frame hollow section 70.

[0036] The present invention is not limited to the embodiments described above, and can be freely modified without departing from the spirit of the invention.

[0037] The joinery according to this embodiment comprises a frame, the vertical frame of the frame is provided with a hollow vertical section that allows drainage to the outside, a notch is formed in a part of the visible wall of the hollow vertical section, a part of the visible wall of the lower frame of the frame fits into the notch and forms a supplementary wall for the hollow vertical section, and a drainage hole communicating with the hollow vertical section is formed in the supplementary wall for the hollow vertical section.

[0038] In this type of fixture, condensation and other liquids can be discharged to the outside through drainage holes, and the drainage holes are kept covered within the hollow section of the vertical frame, preventing fluids such as smoke and water from entering the interior from the outside.

[0039] If drainage components are provided in the drainage hole, the intrusion of fluid from the outside can be further prevented.

[0040] If the aforementioned drainage component can be attached and detached from the indoor side, maintenance will be easier.

[0041] The aforementioned vertical frame is a metal vertical frame, which may be combined with a resin vertical frame, and the aforementioned lower frame is a metal lower frame, which may also be combined with a resin lower frame.

[0042] If a thermally expandable member is not provided in the hollow section of the vertical frame at the location that blocks the drainage hole when heated, the number of parts can be reduced. [Explanation of Symbols]
