Description

[Technical field]

[0001] The present disclosure relates to building materials. [Background technology]

[0002] Conventionally, there has been known a fitting in which a door body is housed in a frame body provided at an opening in a building skeleton so that the door body can be opened and closed (for example, see Patent Document 1). The door body is formed by attaching a surface material to both the front and back sides of frame materials assembled on all four sides. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-119378 A Summary of the Invention [Problem to be solved by the invention]

[0004] The door body has mounting parts such as a pivot hinge and a door closer for mounting the door body to be able to open and close relative to the frame body. Since such mounting parts are attached to the periphery of the door body, for example, water sprayed on the door body from the outside of the room may penetrate into the inside of the door body through the mounting parts. The infiltrating water accumulates inside the door body and may contaminate the internal parts such as the filler and insulation housed inside the door body.

[0005] The present disclosure aims to provide a fitting having a door body that prevents internal parts housed inside the door body from being contaminated by infiltrating water. [Means for solving the problem]

[0006] The present disclosure relates to a fitting having a frame body provided at an opening, and a door body that is placed inside the frame body so as to be able to be opened and closed, wherein the door body has a frame material formed by assembling an upper frame material, a lower frame material, and a pair of left and right vertical frame materials all around, and the frame materials form a drainage path.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. This embodiment shows a hinged door 1 as a fixture. The hinged door 1 is, for example, a front door. The hinged door 1 is configured by fitting a door body 3 inside a frame body 2 provided at an opening of a building so that the door body 3 can be opened and closed.

[0009] In Fig. 2 and Fig. 3, X1 indicates the outdoor side of the hinged door 1, and X2 indicates the indoor side of the hinged door 1. In the hinged door 1, the direction connecting the outdoor side X1 and the indoor side X2 (thickness direction of the door body 3) is the "front direction", and the surface arranged along the front direction is the "front surface". The side surface of the door body 3 facing the outdoor side X1 and the indoor side X2 is the "visible surface". The "up and down" direction of the hinged door 1 is the up and down direction along the vertical direction. The "width direction" of the hinged door 1 is the left and right direction when the hinged door 1 is viewed from the front. In the hinged door 1, the direction toward the outer periphery of the frame body 2 is the "outside", and the surface facing the outside is the "outside surface". In the hinged door 1, the direction toward the inner periphery of the frame body 2 is the "inside", and the surface facing the inside is the "inside surface".

[0010] First, the frame 2 will be described.

[0011] The frame body 2 is formed by framing an upper frame 21, a lower frame 22, a door-end side vertical frame 23, and a hanging side vertical frame 24 in a rectangular shape around all four sides that follow the shape of the opening.

[0012] As shown in FIG. 2, the upper frame 21 has an upper frame main body 211 and a door stop portion 212.

[0013] The upper frame body 211 is made of a metal profile extending in the longitudinal direction of the upper frame 21, and is formed into a rectangular cross section having a hollow portion 211a. Steel plates 211f, 211g, and 211h are attached by welding or the like to a facing surface 211c on the exterior side X1 of the upper frame body 211, a facing surface 211d on the interior side X2, and a bottom surface 211e. The steel plates 211f, 211g, and 211h are provided along the longitudinal direction of the upper frame 21. The steel plates 211f, 211g, and 211h are thicker than the plate thickness of the upper frame body 211. This reinforces the upper frame 21.

[0014] An L-shaped metal fitting 210 for attaching the upper frame 21 to the building frame (not shown) is fixed to the upper surface 211b of the upper frame body 211 with a plurality of screws 21a. The L-shaped metal fitting 210 has an exterior wall portion 210a extending upward from the end of the exterior side X1. The exterior wall portion 210a and the steel plate 211f of the exterior side X1 are arranged flush toward the exterior side X1. A waterproof tape 213 is attached from the exterior side X1 to cover the gap between the exterior wall portion 210a and the steel plate 211f.

[0015] The door stop portion 212 is disposed on the indoor side X2 of the upper frame body 211, and extends in the longitudinal direction of the upper frame 21. The door stop portion 212 has an airtight material mounting base 2121 formed by an extruded material made of a metal such as aluminum or a resin, a cover material 2122 made of a metal such as aluminum or steel that covers the airtight material mounting base 2121 from the indoor side X2, and an upper frame side airtight material 2123.

[0016] The airtight material mounting base 2121 is fixed to the steel plate 211g on the indoor side X2 of the upper frame body 211 by screws 212a and 212b from the indoor side X2. The lower end of the airtight material mounting base 2121 is disposed so as to protrude downward from the steel plate 211h. The upper frame side airtight material 2123 is fixed to the lower end of the airtight material mounting base 2121 from the outdoor side X1.

[0017] The cover material 2122 is attached to the airtight material mounting base 2121 and covers three sides of the airtight material mounting base 2121, including the upper frame side airtight material 2123, from the indoor side X2. This covers and conceals the upper frame side airtight material 2123 so that it is difficult for people passing through the hinged door 1 to see it.

[0018] The upper frame side airtight material 2123 is made of a hollow elastic member made of rubber or resin. The upper frame side airtight material 2123 protrudes from the lower end of the airtight material mounting base 2121 toward the outside side X1 along the length direction of the upper frame 21. As shown in Fig. 2, when the door body 3 is in the closed position, the upper frame side airtight material 2123 abuts against the upper end of the door body 3 from the inside side X2, and airtightly seals the gap with the door body 3.

[0019] As shown in FIG. 2, the lower frame 22 has a lower frame main body 221 and a door stop portion 222.

[0020] The lower frame body 221 is made of a metal profile extending in the longitudinal direction of the lower frame 22, and is formed into a rectangular cross section having a hollow portion 221a. An L-shaped bracket 220 for attaching the lower frame 22 to the framework of a building (not shown) is fixed to the lower surface 221b of the lower frame body 221 by a plurality of screws 22a.

[0021] The L-shaped metal fitting 220 has an exterior wall portion 220a extending downward from an end portion on the exterior side X1. A facing surface 221c on the exterior side X1 of the lower frame body 221 is disposed closer to the exterior side X1 than the exterior wall portion 220a of the L-shaped metal fitting 220. A waterproof tape 223 is attached from the exterior side X1 to cover the gap between the exterior wall portion 220a of the L-shaped metal fitting 220 and the lower surface 221b of the lower frame body 221.

[0022] The door stop portion 222 is disposed on the indoor side X2 of the lower frame body 221, and extends in the longitudinal direction of the lower frame 22. The door stop portion 222 has an airtight material mounting base 2221 formed of an extruded material made of a metal such as aluminum or resin, a cover material 2222 made of a metal such as aluminum or steel that covers the airtight material mounting base 2221 from the indoor side X2, and a lower frame side airtight material 2223. The lower frame side airtight material 2223 is fixed to the airtight material mounting base 2221 from the outdoor side X1 along the longitudinal direction of the lower frame 22.

[0023] The cover material 2222 extends from the visible surface 221c of the outside X1 of the lower frame body 221 toward the inside X2 along the upper surface 221e of the lower frame body 221. The cover material 2222 protrudes toward the inside X2 beyond the visible surface 221d of the inside X2 of the lower frame body 221. The end of the inside X2 of the cover material 2222 is supported from below by an L-shaped angle material 224 attached to the visible surface 221d of the inside X2 of the lower frame body 221. The cover material 2222 covers three sides of the airtight material mounting base 2221 and the lower frame side airtight material 2223 from the inside X2, namely, the lower surface side, the inside X2 side, and the upper surface side. This covers the lower frame side airtight material 2223 so that it is difficult for people passing through the hinged door 1 to see it.

[0024] The lower frame side airtight material 2223 is made of a hollow elastic member made of rubber or resin. The lower frame side airtight material 2223 protrudes from the airtight material mounting base 2221 toward the outside side X1. As shown in Fig. 2, when the door body 3 is in the closed position, the lower frame side airtight material 2223 abuts against the lower part of the door body 3 from the inside side X2 of the room, and airtightly seals the gap between the door body 3.

[0025] 2, the upper surface 221e of the lower frame body 221 is disposed at approximately the same height as the floor surface FL1 of the outside side X1. The upper end of the cover material 2222 is disposed at approximately the same height as the floor surface FL2 of the inside side X2.

[0026] The door-end vertical frame 23 disposed on the right side in FIGS. 1 and 3 has a vertical frame body 231, steel plates 232a to 232c made of steel or the like, abutment portion 233, and a door stop portion 234.

[0027] The vertical frame body 231 is made of a metal shaped material extending in the length direction of the front-end vertical frame 23, and is formed with a rectangular cross section having a hollow portion 231a. An L-shaped metal fitting 230 for attaching the front-end vertical frame 23 to the building frame (not shown) is fixed to a visible surface 231b on the indoor side X2 of the vertical frame body 231 with a plurality of screws 23a.

[0028] Steel plates 232a, 232b are attached to a visible surface 231c and an inner surface 231d of the vertical frame body 231 on the outdoor side X1 by welding or the like.

[0029] The butt joint 233 is disposed so as to face the door end side of the door body 3 housed in the frame body 2. The butt joint 233 has a hollow shape formed with a substantially rectangular cross section from a steel plate such as steel. The butt joint 233 is fixed to the steel plate 232b from the inside of the door end vertical frame 23 by welding or the like. An exterior surface portion 233a of the butt joint 233 facing the exterior side X1 extends outward and covers the steel plate 232a from the exterior side X1.

[0030] The indoor side X2 of the butt joint 233 protrudes toward the indoor side X2 beyond the vertical frame body 231. A steel plate 232c is attached to the indoor surface portion 233b facing the indoor side X2 of the butt joint 233 by welding or the like. As a result, the steel plates 232a, 232b, and 232c are formed in a crank shape spanning the outdoor side X1 of the vertical frame body 231 and the indoor side X2 of the butt joint 233, as shown in FIG. 3, and are provided along the length direction of the door end side vertical frame 23. The steel plates 232a, 232b, and 232c are thicker than the plate thickness of the vertical frame body 231 and the butt joint 233. This reinforces the door end side vertical frame 23.

[0031] The door stop portion 234 is disposed on the steel plate 232c and extends in the longitudinal direction of the door end side vertical frame 23. The door stop portion 234 has an airtight material mounting base 2341 formed by an extruded material made of a metal such as aluminum or a resin, a cover material 2342 that covers the airtight material mounting base 2341 from the indoor side X2, and a door end side airtight material 2343.

[0032] The airtight material mounting base 2341 is fixed to the steel plate 232c from the indoor side X2 by the screw 234a. The inner end of the airtight material mounting base 2341, which is disposed on the door body 3 side, is disposed so as to protrude inward from the steel plate 232c. The door-end side airtight material 2343 is fixed to the inner end of the airtight material mounting base 2341 from the indoor side X1.

[0033] The cover material 2342 is attached to the airtight material mounting base 2341 and covers three sides of the airtight material mounting base 2341, including the door-end side airtight material 2343, from the indoor side X2. This covers and conceals the door-end side airtight material 2343 so that it is difficult for people passing through the hinged door 1 to see it.

[0034] The door-end side airtight material 2343 is made of a hollow elastic member made of rubber or resin. The door-end side airtight material 2343 protrudes from the inner end of the airtight material mounting base 2341 toward the outside side X1 along the length of the door-end side vertical frame 23. As shown in Fig. 3, when the door body 3 is in the closed position, the door-end side airtight material 2343 abuts against the door-end side end of the door body 3 from the inside side X2, and airtightly seals the gap between the door body 3 and the door body 3.

[0035] The hanging side vertical frame 24 arranged on the left side in FIGS. 1 and 3 has a vertical frame main body 241, steel plates 242a to 242c made of steel or the like, a metal plate 243, and a door stopper portion 244.

[0036] The vertical frame body 241 is made of a metal shaped material extending in the length direction of the hanging-side vertical frame 24, and is formed into a rectangular cross section with a hollow portion 241a. An L-shaped bracket 240 for attaching the hanging-side vertical frame 24 to the building frame (not shown) is fixed to a visible surface 241b on the indoor side X2 of the vertical frame body 241 with a plurality of screws 24a.

[0037] Steel plates 242a, 242b are attached to a visible surface 241c and an inner surface 241d of the vertical frame body 241 on the outdoor side X1 by welding or the like.

[0038] The metal plate 243 is formed of a steel plate such as steel, and is arranged so as to face the hanging side of the door body 3 housed in the frame body 2. The metal plate 243 is formed in a crank shape extending from the outdoor side X1 to the indoor side X2 of the vertical frame main body 241. In detail, the metal plate 243 covers the surfaces of the steel plates 242a and 242b, respectively, and is bent inward toward the door body 3 at the end of the indoor side X2. A steel plate 242c is attached to the indoor side X2 of the metal plate 243 by welding or the like. The steel plates 242a, 242b, and 242c are thicker than the vertical frame main body 241 and the metal plate 243. This reinforces the hanging side vertical frame 24.

[0039] The door stop portion 244 is disposed on the steel plate 242c and extends in the longitudinal direction of the hanging-side vertical frame 24. The door stop portion 244 has an airtight material mounting base 2441 formed by an extruded material made of a metal such as aluminum or a resin, a cover material 2442 that covers the airtight material mounting base 2441 from the indoor side X2, and a hanging-side airtight material 2443.

[0040] The airtight material mounting base 2441 is fixed to the steel plate 242c from the indoor side X2 by the screw 244a. The inner end of the airtight material mounting base 2441, which is disposed on the door body 3 side, is disposed so as to protrude inward from the steel plate 242c. The door-end side airtight material 2343 is fixed to the inner end of the airtight material mounting base 2441 from the indoor side X1.

[0041] The cover material 2442 is attached to the airtight material mounting base 2441 and covers three sides of the airtight material mounting base 2441 including the hanging side airtight material 2443 from the indoor side X2, that is, the outer side, the inner side, and the indoor side X2. This covers and conceals the hanging side airtight material 2443 so that it is difficult for people passing through the hinged door 1 to see it.

[0042] The hanging side airtight material 2443 is made of a hollow elastic member made of rubber or resin. The hanging side airtight material 2443 protrudes from the inner end of the airtight material mounting base 2441 toward the outside side X1 along the length of the hanging side vertical frame 24. As shown in Fig. 3, when the door body 3 is in the closed position, the hanging side airtight material 2443 abuts against the hanging side end of the door body 3 from the inside side X2, and airtightly seals the gap with the door body 3.

[0043] Next, the door body 3 will be described.

[0044] The door body 3 has a frame material 31, an exterior panel material 32a, an interior panel material 32b, an exterior design material 33a, and an interior design material 33b.

[0045] The frame material 31 is constructed by assembling an upper frame material 311, a lower frame material 312, an end side vertical frame material 313, and a hanging side vertical frame material 314 in a rectangular shape around all four sides. The upper frame materials 311, 411, the lower frame materials 312, 412, the end side vertical frame materials 313, 413, and the hanging side vertical frame materials 314, 414 are made of shaped materials made of metals such as aluminum and steel, carbon, CFRP (Carbon Fiber Reinforced Plastics), etc. The upper frame material 311, the lower frame material 312, the end side vertical frame material 313, and the hanging side vertical frame material 314 all have a hollow shape with a polygonal cross section, and have hollow portions 311a, 312a, 313a, and 314a inside, respectively.

[0046] The outdoor panel material 32a and the indoor panel material 32b are made of plate material such as wood, resin, or metal. The outdoor panel material 32a and the indoor panel material 32b are arranged to sandwich the rectangularly assembled frame material 31 from the outdoor side X1 and the indoor side X2, and are fixed to the frame material 31 with a plurality of screws 32a1, 32b1. The internal space surrounded by the frame material 31 and the outdoor panel material 32a and the indoor panel material 32b accommodates internal parts (not shown) such as a filler material such as paper honeycomb or a heat insulating material.

[0047] The outdoor design material 33a and the indoor design material 33b are finishing materials that form the surfaces of the outdoor side X1 and the indoor side X2 of the door body 3, respectively, and make up the overall design of the door body 3. The outdoor design material 33a and the indoor design material 33b are made of glass plates, metal plates, resin plates, ceramic plates, metal tiles, resin tiles, porcelain tiles, stone, etc. The outdoor design material 33a and the indoor design material 33b are arranged so as to cover the surfaces of the outdoor side panel material 32a and the indoor side panel material 32b, and are attached to the outdoor side panel material 32a and the indoor side panel material 32b with an adhesive or the like.

[0048] As shown in Figures 1 and 3, the door body 3 has handles 3a for opening and closing that extend in the vertical direction on the surfaces of the outside surface X1 and the inside surface X2 of the door end side. However, the shape of the handle 3a is arbitrary and is not limited to a shape extending in the vertical direction. A pair of upper and lower locks 3b, 3b are provided in the hollow portion 313a of the door end side vertical frame member 313 of the door body 3. The door body 3 opens the inside of the frame body 2 by rotating the door end side toward the outside surface X1 from the closed state around the axes of pivot hinges 3c, 3c provided at the upper and lower parts of the hanging side.

[0049] The upper and lower pivot hinges 3c, 3c are mounting parts attached to the upper frame member 311 and the lower frame member 312 of the frame member 31. The pivot hinges 3c, 3c are provided so as to penetrate the upper frame member 311 and the lower frame member 312. As shown in Fig. 4, a through hole 311c through which the upper pivot hinge 3c penetrates is formed in the upper surface 311b on the hanging side of the upper frame member 311. This through hole 311c is a portion through which water may enter the inside of the door body 3.

[0050] A concealed door closer 3d is disposed on the upper part of the door body 3. The door closer 3d has a function of closing the door body 3 slowly and smoothly at a safe speed. The door closer 3d is a mounting part attached to the upper frame material 311. As shown in FIG. 2, the door closer 3d has a door closer body 3d1 housed in the hollow part 311a of the upper frame material 311 and a hinge part 3d2 housed in the hollow part 211a of the upper frame body 211. The door closer body 3d1 and the hinge part 3d2 are connected by a connection part 3d3 penetrating the upper frame material 311. As shown in FIG. 4, a through hole 311d through which the connection part 3d3 of the door closer 3d penetrates is formed on the upper surface 311b of the hanging side of the upper frame material 311, closer to the door tip side than the through hole 311c. This through hole 311d is a part through which water may penetrate into the inside of the door body 3.

[0051] Next, the drainage path of the frame material 31 will be described with reference to Fig. 4. In Fig. 4, in order to show the drainage path 300 of the frame material 31, the illustration of each component provided on the frame material 31 is omitted.

[0052] As shown in Fig. 4, the frame material 31 has a vertically extending structure. That is, the door-end vertical frame material 313 and the hanging-side vertical frame material 314 are arranged to sandwich the upper frame material 311 and the lower frame material 312 from the left and right. Both end faces 311e, 311e of the upper frame material 311 and both end faces 312b, 312b of the lower frame material 312 are open.

[0053] Both ends of the upper frame member 311 are connected to the upper ends of the door end side vertical frame member 313 and the hanging end side vertical frame member 314, respectively. Both ends of the lower frame member 312 are connected to the lower ends of the door end side vertical frame member 313 and the hanging end side vertical frame member 314, respectively. Both end faces 311e, 311e of the upper frame member 311 and both end faces 312b, 312b of the lower frame member 312 are respectively arranged inside the hollow portion 313a of the door end side vertical frame member 313 and the hollow portion 314a of the hanging end side vertical frame member 314. As a result, the hollow portions 311a, 312a, 313a, 314a of the upper frame member 311, the lower frame member 312, the door end side vertical frame member 313 and the hanging end side vertical frame member 314 are connected around the four sides, forming a drainage path 300 inside the frame member 31.

[0054] 2 and 4, drainage holes 312d are provided for draining water that has entered the frame material 31 downward from the frame material 31. The drainage holes 312d open to the lower end surface of the frame material 31. Specifically, the drainage holes 312d open to the lower surface 312c of the lower frame material 312.

[0055] A plurality of drainage holes 312d may be provided in the frame material 31. Two drainage holes 312d, 312d are provided on the lower surface 312c of the lower frame material 312 shown in FIG. 4. The two drainage holes 312d, 312d may be provided at both ends of the lower end surface of the frame material 31. In this case, the two drainage holes 312d, 312d are provided separately at the end on the door end side and the end on the hanging side of the lower end surface of the frame material 31. FIG. 4 shows an example in which the two drainage holes 312d, 312d are provided at both ends of the lower frame material 312. The two drainage holes 312d, 312d are provided separately at the end on the door end side and the end on the hanging side of the lower frame material 312.

[0056] As shown in Fig. 4, when water such as rain blowing from the outside X1 enters the inside of the frame material 31 through the through holes 311c, 311d of the upper frame material 311 of the door body 3, the water flows left and right through the hollow portion 311a of the upper frame material 311 and flows into the hollow portion 313a of the door end vertical frame material 313 and the hollow portion 314a of the hanging end vertical frame material 314. The water that flows into the door end vertical frame material 313 and the hanging end vertical frame material 314 flows down the respective hollow portions 313a, 314a and flows into the hollow portion 312a of the lower frame material 312. The water that flows into the lower frame material 312 flows left and right through the hollow portion 312a of the lower frame material 312 and flows out below the door body 3 from one of the drainage holes 312d.

[0057] In this way, water that has entered the door body 3 is discharged from the drain hole 312d to the outside of the door body 3 by the drain path 300 formed inside the frame material 31. Therefore, the water that has entered does not come into contact with internal components such as the filler or insulating material contained inside the frame material 31, and there is no risk of contaminating the internal components. Because the drain hole 312d opens to the lower surface 312c of the lower frame material 312, there is no risk of both the outdoor side X1 and the indoor side X2 of the door body 3 getting wet by the discharged water.

[0058] When the drainage holes 312d, 312d are provided on the door tip side and the hanging side of the lower frame material 312, respectively, water that has entered the frame material 31 can be drained to the outside from either the door tip side or the hanging side of the door body 3. Therefore, for example, even if the door body 3 is inclined toward the door tip side or the hanging side depending on the installation state of the door body 3, water that has entered inside the frame material 31 can be reliably drained to the outside of the door body 3.

[0059] The door body 3 of this embodiment described above provides the following advantages.

[0060] (1) A fixture (swing door 1) having a door body 3 that can be opened and closed inside a frame body 2. The door body 3 has a frame material 31 formed by assembling an upper frame member 311, a lower frame member 312, and a pair of left and right vertical frame members (a door-end side vertical frame member 313 and a hanging-side vertical frame member 314) all around, and the frame material 31 forms a drainage path 300.

[0061] According to (1) above, water that has infiltrated inside the door body 3 can be drained through the drainage path 300 of the frame material 31, so there is no risk of the internal parts housed inside the door body 3 being contaminated by the infiltrating water.

[0062] (2) In the building fixture (hinged door 1) described in (1) above, the upper frame member 311, the lower frame member 312 and the vertical frame members (the door-end side vertical frame member 313 and the hanging-end side vertical frame member 314) are each hollow, and the interiors of the vertical frame members (the door-end side vertical frame member 313 and the hanging-end side vertical frame member 314) are connected to the interiors of the upper frame member 311 and the lower frame member 312, and a drainage hole 312d is provided in the lower frame member 312.

[0063] According to (2) above, water that has penetrated into the door body 3 can be smoothly allowed to flow down to the lower frame material 312 and then discharged to the outside of the door body 3 through the drainage holes 312d provided in the lower frame material 312, thereby further improving the drainage performance of the door body 3.

[0064] (3) In the fitting (hinged door 1) described in (2) above, the drainage holes 312d are disposed at both the left and right ends of the lower frame material 312.

[0065] According to the above (3), water that has entered the frame material 31 can be discharged to the outside from either the door end side or the hanging side of the door body 3. Therefore, even if the door body 3 is inclined toward the door end side or the hanging side, water that has entered inside the frame material 31 can be reliably discharged to the outside of the door body 3.
