[0009] [Configuration of this embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 3, a ventilation door 1 as a fixture according to this embodiment divides a building opening (not shown) into an indoor space and an outdoor space, and comprises a door frame 2 installed in the building opening, and a door body 3 arranged so as to be able to open and close within the door frame 2. The door body 3 comprises a frame body 30, and a ventilation unit 40 as a frame unit arranged within the frame body 30. A door closer and hinges 24 are provided between the door frame 2 and the door body 3. In the following description, the left-right direction of the ventilation door 1 is the X-axis direction, the up-down direction of the ventilation door 1 is the Y-axis direction, and the front direction of the ventilation door 1 is the Z-axis direction. The X, Y, and Z-axis directions are perpendicular to each other.

[0010] The door frame 2 is composed of an upper door frame 21, a lower door frame 22, and left and right vertical door frames 23. The hanging side vertical door frame 23 is connected to a hanging side vertical stile 33 (described later) via a hinge 24, so that the door frame 2 supports the door body 3 so that it can be rotated open and closed toward the outside of the room. The door frame 30 includes an upper frame 31, a lower frame 32, and left and right vertical frames 33, which are assembled vertically. Sealing materials (not shown) are provided where the upper frame 31, lower frame 32, and vertical frames 33 meet. Cap members (not shown) are attached to the top and bottom ends of the vertical frames 33. The vertical frame 33 at the door end is equipped with a handle, lock, etc. In this embodiment, the ventilation unit 40 of the door body 3 is configured as a double-hung window, and includes an upper inner frame 41, a lower inner frame 42, and left and right vertical inner frames 43 framed vertically, and an upper shoji screen 4 and a lower shoji screen 5 that can open and close the opening formed by the upper inner frame 41, the lower inner frame 42, and the left and right vertical inner frames 43. The upper shoji screen 4 and the lower shoji screen 5 are arranged to be movable in the Y-axis direction, and the upper and lower halves of the opening can be opened and closed by moving the upper shoji screen 4 and the lower shoji screen 5 up and down, respectively. In this embodiment, multiple horizontal lattices are arranged vertically on the exterior side of the ventilation unit 40, but this is not limited to this.

[0011] The upper frame 31, lower frame 32, and left and right vertical frames 33 of the frame body 30 are each composed of a composite frame material having a metal profile 61 on the exterior side and a plastic profile 71 on the interior side. Each metal profile 61 has a hollow portion 60 and is configured to have a roughly rectangular frame cross section, and each plastic profile 71 is positioned on the interior side of the metal profile 61 and engages with the metal profile 61, covering the metal profile 61 from the interior side. In this embodiment, the metal profile 61 is formed from an aluminum extrusion, and the plastic profile 71 is formed from a synthetic resin extrusion.

[0012] The upper and lower frames 31 and 32 are arranged along the X-axis. The end of the lower frame 32 is arranged between the exterior facing surface 331 and the interior facing surface 332 of the vertical frame 33, described below, and extends into the inner peripheral facing surface 334 in the X-axis direction. While FIG. 4 shows the end of the lower frame 32 on the hanging side, the area around the end of the lower frame 32 is configured in a similar manner. A drain outlet 35, shown in FIGS. 4 to 6, is cut into the upper surface 321 of the end of the lower frame 32 that extends into the left and right vertical frames 33. The drain outlet 35 drains water, such as rainwater, that seeps between the vertical frame 33 and the vertical inner frame 43 downward. Similarly, the end of the upper frame 31 is arranged between the exterior facing surface 331 and the interior facing surface 332 of the vertical frame 33, and extends into the inner peripheral facing surface 334.

[0013] As shown in Figures 5 and 6, the left and right vertical frames 33 have an exterior-facing surface 331, an interior-facing surface 332, an outer peripheral facing surface 333, and an inner peripheral facing surface 334. The exterior-facing surface 331 and the interior-facing surface 332 each have extending portions 331A, 332A that extend inward beyond the inner peripheral facing surface 334. The tip of extending portion 331A is bent toward the interior of the room and abuts and engages with a frame facing surface 45 (described later) of the vertical inner frame 43, while the tip of extending portion 332A is bent toward the exterior and abuts against the frame facing surface 45 of the vertical inner frame 43. The exterior end of the bent portion of extending portion 332A abuts against a water-stopping piece 46 (described later) of the vertical inner frame 43. The exterior facing surface 331 is formed by the metal facing surface 62 on the exterior side of the metal extrusion 61, the interior facing surface 332 is formed by the resin facing surface 72 of the resin extrusion 71, the outer periphery facing surface 333 is formed by the metal facing surface 63 on the exterior side of the metal extrusion 61, and the interior periphery facing surface 334 is formed by the metal facing surface 64 on the interior side of the metal extrusion 61 and the resin facing surface 73 extending outward from the resin facing surface 72 of the resin extrusion 71. The metal extrusion 61 that forms the vertical frame 33 has metal hook-shaped portions 66, 67, and the resin extrusion 71 has resin hook-shaped portions 76, 77 that engage with the metal hook-shaped portions 66, 67. In this embodiment, the metal hook portions 66, 67 are formed in a hook-like shape extending from the metal facing surface 65 on the interior side of the metal extrusion 61, and the resin hook portions 76, 77 are formed at the tip of the resin facing surface 73 extending from the resin facing surface 72 (interior facing surface 332) of the resin extrusion 71 to the exterior side. In this embodiment, four resin facing surface portions 73 are formed. Of these, the resin hook portion 76 is formed on the resin facing surface 73 located on the outermost side, and the resin hook portion 77 is formed on the resin facing surface 73 located on the innermost side. The resin hook portion 76 is located on the outer side of the metal hook portion 66, and by engaging with each other, they form the engagement portion 36 on the inner peripheral facing surface 334. The resin hook portion 77 is located on the inner side of the metal hook portion 67, and by engaging with each other, they form the engagement portion 37 located on the outer side of the engagement portion 36.

[0014] The upper inner frame 41, lower inner frame 42, and left and right vertical inner frames 43 of the ventilation unit 40 are each composed of a metal inner frame body 81 and a resin cover material 82 that engages with the inner frame body 81 from the inside of the room, and the resin cover material 82 is arranged to cover the inner frame body 81 from the inside of the room. In this embodiment, the inner frame body 81 is formed from an aluminum extrusion, and the resin cover material 82 is formed from a synthetic resin extrusion.

[0015] The inner frame body 81 of the left and right vertical inner frames 43 has a frame projection surface 45 against which the extensions 331A, 332A abut, a water stop piece 46 extending outward from the frame projection surface 45 along the X-axis between the exterior-facing surface 331 and the interior-facing surface 332 to prevent water from seeping in from the exterior to the interior, and a frame exterior-facing surface 47, a frame interior-facing surface 48, and a frame intermediate-facing surface 49 extending inward from the frame projection surface 45. The frame projection surface 45 has an engagement portion 451 formed on a portion of the frame exterior side relative to the water stop piece 46, and the tip of the extension 331A engages with this engagement portion 451. The frame projection surface 45 is connected to the metal projection surface 64 of the vertical stile 33 by a connecting screw 452. The expected position where the connecting screw 452 connects to the metal visible surface portion 64 is the indoor end of the metal visible surface portion. Therefore, the engagement portion 36 is reinforced by both the connecting screw 452 and the water stop piece portion 46, increasing the engagement strength.

[0016] A tip 461 (tip edge) of the water stop piece 46 in the X-axis direction is located on the inner periphery of the engagement portion 36 and is disposed opposite the resin hook portion 76 in the X-axis direction. The tip 461 may be disposed in contact with the inner periphery projection surface 334, or may be disposed with a gap of 3 mm or less from the inner periphery projection surface 334. As shown in FIG. 4 , the lower end 462 of the water stop piece 46 is disposed along the upper surface 321 of the bottom frame 32, and is disposed on the indoor side of the drain outlet 35 and on the outdoor side of the resin profile 71 of the bottom frame 32. Even if there is a gap of 3 mm or less as described above, surface tension acts between the tip 461 and the inner periphery projection surface 334, preventing water from entering the indoor side through this gap.

[0017] In the above ventilation door 1, even if water such as rainwater seeps in from the outside between the vertical stile 33 and the vertical inner frame 43, the water is prevented from further seeping inside the room and is drained. That is, if water seeps in from the outside between the connecting portion of the upper stile 31 and the vertical stile 33 or between the vertical inner frame 43 and the vertical stile 33, even if the water tries to seep inside the room along the frame projection surface 45 of the vertical inner frame 43 or the inner peripheral projection surface 334 of the vertical stile 33, the water stop pieces 46 extending from the frame projection surface 45 are positioned as described above, so that the water is prevented from seeping inside the room beyond the water stop pieces 46, and the water seeping in from the outside flows downward on the outside beyond the water stop pieces 46 and is drained through the drain hole 35 formed in the upper surface 321 of the lower stile 32.

[0018] [Variations] In the above embodiment, the ends of the upper frame 31 and the lower frame 32 are disposed so as to extend into the inner peripheral visible surface 334 of the vertical frame 33, but they may be disposed so as not to extend into the vertical frame 33. In this case, the drainage opening 35 may not be formed in the lower frame 32. In the above embodiment, even if a gap is formed between the tip 461 of the water-stopping piece 46 and the inner peripheral projected surface portion, the gap is set to be within 3 mm, but if water infiltration through the gap can be prevented by surface tension or the like, a gap larger than 3 mm may be formed as long as the water infiltration can be prevented. In the above embodiment, the tip 461 of the water stop piece 46 is positioned opposite the engagement portion 36 in the X-axis direction, but it may be positioned on the outside or inside of the room relative to the engagement portion 36. In addition, the projected position of the lower end 462 of the water stop piece 46 is positioned on the outside of the room relative to the resin profile 71 in the lower frame 32, but it may be positioned on the side of the resin profile 71. In the above embodiment, the engagement portions 36, 37 are formed by the engagement between the metal hook portions 66, 67 and the resin hook portions 76, 77, but this type of engagement is not necessary as long as the metal profile 61 and the resin profile 71 are joined. In the above embodiment, the upper frame 31, the lower frame 32, and the left and right vertical frames 33 are each configured as a composite frame material having a metal profile 61 and a resin profile 71, but they may be configured from either a metal profile or a resin profile instead of a composite frame material. In this case, the upper inner frame 41, the lower inner frame 42, and the left and right vertical inner frames 43, as well as the upper door frame 21, the lower door frame 22, and the left and right vertical door frames 23 may also be configured from either a metal profile or a resin profile instead of the above-mentioned configuration. In the above embodiment, the vertical inner frame 43 is connected to the vertical stile 33 by a connecting screw 452 to increase the rigidity and fire resistance of the ventilation door 1, but if the ventilation door 1 can be constructed without this connecting screw 452, the configuration of the connecting screw 452 may be omitted. In the above embodiment, the ventilation unit 40 is configured as a double-hung window, but it may also be various other windows such as a sliding window, a casement window, a single-sliding window that slides up and down or left and right, etc. Also, instead of the ventilation unit 40, a frame unit that does not allow ventilation, such as a fixed window, may be used.

[0019] [Summary of the invention] The building fixture of the present invention comprises a door frame and a door body that is arranged within the door frame so that it can be opened and closed. The door body comprises a frame body and a frame unit that is arranged within the frame body. The frame body comprises an upper frame, a lower frame, and left and right vertical frames. The frame unit comprises an upper inner frame, a lower inner frame, and left and right vertical inner frames. The vertical frames have an exterior facing surface, an interior facing surface, an outer facing surface, and an interior facing surface. The exterior facing surface and the interior facing surface each have an extension that extends inward beyond the inner facing surface. The vertical inner frame has a frame facing surface to which the extension abuts, and a water-stopping piece that extends outward from the frame facing surface between the exterior facing surface and the interior facing surface and prevents water from entering from the outside to the inside of the room. According to the building fixture of the present invention, the vertical inner frame of the door body has the above-mentioned water-stopping piece, so even if water penetrates inside the room beyond the exterior-facing surface of the vertical stile, the penetrated water can be blocked by the water-stopping piece located on the exterior side of the exterior-facing surface.This prevents water such as rainwater from penetrating from the exterior to the interior through the gap between the vertical stile and the vertical inner frame, thereby improving water-stopping properties.

[0020] In the building fixture of the present invention, the end of the lower frame is positioned between the exterior visible surface and the interior visible surface of the vertical frame, extending into the inner visible surface, a drain outlet is formed at the end of the lower frame, and the water-stopping piece portion may be positioned such that its lower end is along the upper surface of the lower frame and is positioned on the interior side of the drain outlet. With this configuration, the end of the lower frame is positioned between the outdoor visible surface and the indoor visible surface of the vertical frame, extending into the inner visible surface, thereby improving the strength of the frame body.In addition, since the above-mentioned water-stopping piece is positioned inside the room rather than the drain outlet, even if water blocked by the water-stopping piece flows downward, it can be drained outside the room rather than the water-stopping piece, preventing water from entering inside the room rather than the water-stopping piece.

[0021] In the building fixture of the present invention, the tip of the water-stopping piece may be positioned in contact with the inner peripheral visible surface portion, or may be positioned with a gap of 3 mm or less from the inner peripheral visible surface portion. With this configuration, the tip of the water stop piece is positioned in contact with the inner peripheral visible surface, thereby preventing water from seeping into the room between the tip of the water stop piece and the inner peripheral visible surface. Furthermore, even if there is a gap of 3 mm or less between the tip of the water stop piece and the inner peripheral visible surface, the surface tension of water prevents water from seeping into the room between the tip of the water stop piece and the inner peripheral visible surface.

[0022] In the building fixture of the present invention, the upper frame, the lower frame and the left and right vertical frames are each made of a composite frame material having a metal profile on the outside of the room and a resin profile on the inside of the room, and the metal profile and the resin profile that make up the inner peripheral visible surface portion are made of engaging portions that engage with each other, and the tip of the water-stopping piece portion may be positioned on the inner peripheral side of the engaging portion. With this configuration, by positioning the tip of the water-stopping piece at a position on the inner periphery of the aforementioned engaging portion, the water-stopping piece can prevent water from penetrating from the outside of the room to the engaging portion.

[0023] In the building fixture of the present invention, the projected position of the lower end of the water-stopping piece may be positioned on the outdoor side of the resin profile in the lower frame. This configuration can prevent water from seeping in from the outside of the room to the part of the lower frame where the metal profile and the resin profile are joined.

[0024] In the fixture of the present invention, the engaging portion has a metal hook portion formed on the metal profile and a plastic hook portion formed on the plastic profile and engaging with the metal hook portion from the inner periphery, and the water-stopping piece portion may be positioned opposite the plastic hook portion in the viewing direction of the fixture. With this configuration, the resin hook portion is more likely to bend than the metal hook portion, but the water-stopping piece portion arranged as described above can suppress the bending of the resin hook portion, thereby improving the engagement strength at the engagement portion.

[0025] In the building fixture of the present invention, the end of the upper frame may be positioned between the exterior facing surface and the interior facing surface of the vertical frame, extending into the interior facing surface. With this configuration, the end of the upper frame is positioned between the exterior visible surface and the interior visible surface of the vertical frame, extending into the inner visible surface, thereby improving the strength of the frame body.In addition, even if water seeps in between the exterior visible surface of the vertical frame and the end of the upper frame, the aforementioned water-stopping piece can prevent water from seeping into the interior side.

[0026] In the building fixture of the present invention, the frame unit may be composed of a ventilation unit equipped with a shoji screen that can open and close an opening formed by the upper inner frame, the lower inner frame, and the left and right vertical inner frames. With this configuration, the door body can be configured to allow ventilation by opening and closing the shoji screen, while still achieving the above-mentioned effects. [Explanation of symbols]
