[0014] Figure 1 shows a door according to one embodiment of the present invention as seen from inside the room. In Figure 1, reference numeral 1 denotes a door frame that is attached to an opening in a building frame. Reference numeral 2 denotes the door body that is attached to the frame 1 so that it can be opened and closed using hinges 3. The frame 1 is formed into a rectangle by combining a vertical frame 4 on the hanging side, a vertical frame 5 on the door tip side, an upper horizontal frame (upper frame) 6, and a lower horizontal frame (lower frame) 7 using tapping screws (not shown).

[0015] Figures 2, 3, 4, and 5 are enlarged cross-sectional views taken along lines AA, BB, CC, and DD in Figure 1, respectively. Prior to describing the door body 2, the structures of the vertical frames 4, 5, upper frame 6, and lower frame 7 that make up the frame 1 will be described. As shown in Figures 2, 3, and 4, the vertical frames 4, 5, and upper frame 6 are all extruded shapes made of a resin material such as PVC (polyvinyl chloride resin), and the exterior sides of these vertical frames 4, 5, and upper frame 6 are covered with metal covers 37, 38, and 39 made of aluminum alloy or other material and secured in place with fasteners 41, 42, and 43 such as screws and rivets. The metal covers 37, 38, and 39 are provided to prevent deterioration of the resin frame material due to direct sunlight, which could result in a loss of appearance.

[0016] 2, the portion of the vertical frame 4 on the hanging side facing the door body 2 is divided into multiple (four in the illustrated example) hollow portions 4a to 4d in the front direction (indoor / outdoor direction). The outdoor portion of the vertical frame 4 has an extension 4e that extends in the front direction on the side away from the door body 2, and this extension 4e also has a hollow portion 4f that is adjacent to hollow portion 4d.

[0017] Reference numerals 17a, 17b, and 17c denote heat insulating materials fitted into hollow portions 4b, 4c, and 4d adjacent to the door body 2 of the vertical frame 4, respectively, and are made of a foam material such as EPS (expanded polystyrene resin). Reference numeral 4k denotes a U-shaped metal core material such as a steel plate, and this core material 4k is fitted into hollow portion 4d on the outdoor side and fixed to hollow portion 4d with a fixture, double-sided tape, adhesive, or the like (not shown). Heat insulating material 17c in hollow portion 4d is fitted into and fixed to this metal core material 4k.

[0018] Reference numeral 18 denotes an airtight material made of resin or rubber, which is interposed between the frame 1 and the interior surface of the door body 2, and seals the gap between them when the door body 2 is closed. In the vertical frame 4, the airtight material 18 is attached by fitting its base into an airtight material attachment portion 4g formed so as to protrude from the surface of the door body 2. The airtight material 18 has a hollow portion 18a. The heat insulating materials 17a to 17c are located on the outdoor side of the attachment portion of the vertical frame 4 to the airtight material 18, and are disposed in the hollow portions 4b to 4d adjacent to the door body 2, respectively. The hollow portion 4b adjacent to the airtight material mounting portion 4g is further adjacent to the hollow portion 4a and the hollow portion 4c. On the other hand, no heat insulating material is placed in the hollow portion 4a on the indoor side of the attachment portion of the airtight material 18, or in the hollow portion 4f on the outdoor side that is not adjacent to the door body 2. 50 is a pillar that is part of the frame that forms the opening to which the frame body 1 is attached. As shown in Figure 2, in the front direction of the door body 2, at least the position of the door body side front surface 4m of the vertical frame 4 (frame body 1) that is the same as the airtight material 18 and the airtight material mounting portion 4g is made of resin.

[0019] As shown in Figure 3, the vertical frame 5 on the door end side, like the vertical frame 4 on the hanging side, is divided into multiple (four in the illustrated example) hollow sections 5a to 5d in the front direction on the door body 2 side. In addition, the outdoor section of the vertical frame 5 has an extension section 5e that extends in the front direction on the side away from the door body 2, and this extension section 5e also has a hollow section 5f that is adjacent to hollow section 5d. The hollow portion 5b adjacent to the airtight material mounting portion 5g is further adjacent to the hollow portion 5a and the hollow portion 5c.

[0020] Reference numerals 17d, 17e, and 17f denote heat insulating materials fitted into hollow portions 5b, 5c, and 5d on the door body 2 side, and are made of a foam material such as EPS. Reference numeral 5k denotes a metal core material such as a steel plate with a U-shaped cross section. This core material 5k is fitted into hollow portion 5d on the outdoor side and fixed to hollow portion 5d with a fixture, double-sided tape, adhesive, or the like (not shown). Heat insulating material 17f in hollow portion 5d is fitted into and fixed in this metal core material 5k.

[0021] In Figure 3, the airtight material 18 is attached by fitting its base into the airtight material attachment portion 5g formed by protruding from the surface of the vertical frame 5 facing the door body 2. The heat insulating materials 17d to 17f are located on the outdoor side of the attachment portion of the airtight material 18 in the vertical frame 5, and are arranged in hollow portions 5b to 5d adjacent to the door body 2. On the other hand, no heat insulating material is arranged in the hollow portion 5a located on the indoor side of the attachment portion of the airtight material 18, or in the hollow portion 5f located on the outdoor side and not adjacent to the door body 2. 51 is a pillar that is part of the frame that forms the opening to which the door frame 1 is attached.

[0022] 4, like the vertical frames 4 and 5, the upper frame 6 is divided into multiple (three in the illustrated example) hollow portions 6a-6c in the indoor / outdoor direction at its portion on the door body 2 side. The outdoor portion of the upper frame 6 has an extension 6d that extends in the viewing direction on the side away from the door body 2, and this extension 6d also has a hollow portion 6e that is adjacent to the hollow portion 6c.

[0023] Reference numerals 17g and 17h denote heat insulating materials fitted into hollow portions 6b and 6c of the upper frame 6 on the door body 2 side, and are made of a foam material such as EPS.

[0024] In Figure 4, airtight material 18 is attached by fitting its base into airtight material attachment portion 6f formed by protruding from the surface of upper frame 6 facing the door body 2. Heat insulating materials 17g and 17h are located in hollow portions 6b and 6c of upper frame 6 on the outdoor side of the attachment portion of airtight material 18 and adjacent to the door body 2, respectively. On the other hand, no heat insulating material is located in hollow portion 6a on the indoor side of the attachment portion of airtight material 18, or in hollow portion 6e on the outdoor side and not adjacent to the door body 2. Reference numeral 52 denotes a cross member that becomes part of the frame that forms the opening to which door frame 1 is attached. The hollow portion 6a adjacent to the airtight material mounting portion 6f is further adjacent to a hollow portion 6b.

[0025] As shown in Figure 5, the sill 7 of this embodiment is constructed by extruding an exterior frame 7a and an interior frame 7b facing the underside of the door body 2 using extruded profiles made of a metal material such as aluminum alloy. The exterior frame 7a and the interior frame 7b are connected by a rubber or resin insulating material 7c. L1 indicates the ground level on the exterior side of the door. This ground level L1 is set to be at the same level as or slightly lower than the top surface of the sill 7 facing the underside of the door body 2. L2 indicates the level of the dirt floor on the interior side where the door is installed. This level L2 is set to be approximately at the same level as the top surface of a rubber protective material 24 attached to the top surface of the interior portion of the sill 7. The protective material 24 is provided to prevent damage to the top surface of the sill 7 due to the adhesion of sand and to prevent condensation.

[0026] The exterior frame 7a of the bottom frame 7 is covered with a metal cover 40 made of stainless steel plate or the like and fixed to the bottom frame 7 with fasteners 44 such as rivets or screws. The interior frame 7b has a rising portion 7b1 that faces the interior side of the door body 2, and an airtight material 18 that is against the interior surface of the door body 2 is attached to the rising portion 7b1.

[0027] In the lower frame 7 of this embodiment, the outdoor frame 7a has a generally rectangular cross section. The metal cover 40 is composed of a lower surface 40a that covers the outdoor portion below the lower surface 7a1 of the outdoor frame 7a, a visible surface 40b that covers the visible surface 7a2, which is the outdoor vertical surface of the outdoor frame 7a, and an upper surface 40c that covers the upper surface 7a3 of the outdoor frame 7a. The indoor-side end 40d of the metal cover 40 is positioned on the insulating material 7c.

[0028] In this embodiment, the reason why the lower frame 7 is made of an extruded metal material is to prevent deformation when a person's weight is applied to the lower frame 7. Also, by using stainless steel, which is harder than the exterior frame 7a and the interior frame 7b, which are made of extruded metal, for the metal cover 40, damage to the lower frame 7 due to the adhesion of sand and the like can be prevented, and deterioration of the appearance can be prevented. However, the lower frame 7 may also be made of an extruded resin material.

[0029] Next, we will explain the structure of the door body 2 and its attachment structure to the frame 1. The door body 2 has an exterior surface member 8 and an interior surface member 9 made of metal such as steel plate, and end members 10, 11, 12, and 13 provided at the hanging end (Fig. 2), door tip end (Fig. 3), upper end (Fig. 4), and lower end (Fig. 5) of the door body 2, respectively.

[0030] Of these end members 10 to 13, end members 10, 12, and 13 are made of a resin material. Of these end members, end member 10 on the hanging side has a rectangular hollow shape, and each of end members 12 and 13 at the upper and lower ends has a U-shaped cross section.

[0031] On the other hand, the door-leading edge member 11 shown in Fig. 3 is composed of two resin plates 15, 15 with an L-shaped cross section and placed at the indoor and outdoor corners to attach the door-leading cover 14, an outdoor core member 19 made of metal such as steel placed between them, and an indoor core member 20 made of resin fixed to the indoor side of this core member 19 with double-sided tape or the like. The door-leading cover 14 is then attached to the door body 2 by covering this end member 11 with the door-leading cover 14 and fixing it to the core member 19 with fasteners such as rivets or screws (not shown). 22 denotes a resin or rubber sealant attached to the outdoor side of the door-leading cover 14, which abuts against the outdoor-facing surface 38a of the metal cover 38 of the door-leading vertical frame 5 to additionally prevent outside air from entering.

[0032] As shown in Figure 2, end member 10 on the hanging side of door body 2 has a portion thereof that protrudes outward in the view direction of door body 2. With respect to end member 10 on the hanging side of door body 2, exterior surface material 8 and interior surface material 9 do not cover exposed portion 10a, and have a shape formed by bending short, L-shaped visible surface portions 8b, 9b from the ends of visible surface portions 8a, 9a. Surface materials 8, 9 are fixed to end member 10 at visible surface portions 8b, 9b with rivets (not shown) and by adhesive.

[0033] As shown in Figures 4 and 5, at the upper and lower ends of the door body 2, the projected surface portions 8b, 9b of the surface materials 8, 9 are formed to extend to near the center of the projected direction of the door body 2, that is, longer than the projected surface portions 8b, 9b on the hanging side shown in Figure 2, and are fixed to the end members 12, 13 by rivets or adhesives not shown.

[0034] 2, 4 and 5, 17k, 17m and 17n are heat insulating materials arranged and fixed in the end members 10, 12 and 13, respectively, and are provided to improve the heat insulating properties at the end of the door body 2. There are no particular restrictions on the material of these heat insulating materials 17k, 17m and 17n, but it is preferable to use a block-shaped heat insulating material made of the same material as the heat insulating materials 17a to 17h housed in the frame 1.

[0035] Reference numeral 17p denotes a panel-shaped insulating material (insulating panel) that constitutes the door body 2 together with the end members 10-13 and the surface members 8, 9, and this insulating material 17p is housed in a box-shaped frame formed by the outdoor surface member 8, the indoor surface member 9, and the end members 10-13, and is fixed by adhesive. The insulating material 17p is made of the same material as the insulating materials 17a-17n, or a material with higher insulating properties, such as phenolic foam insulation board (manufactured by Asahi Kasei Building Materials Corporation, product name: Neoma Foam (Neoma is a registered trademark)).

[0036] Next, the mounting structure for the hanging side of the door body 2 will be described with reference to Figure 2. Reference numeral 25 denotes a core member made of metal such as steel that reinforces the hanging side of the door body 2. This core member 25 has an L-shaped cross section and is located inside the hollow end member 10, between the exterior corner 10c and the interior corner 10d in the indoor-outdoor direction. Reference numeral 32 denotes a back plate for connection to the mounting plate 3b of the hinge 3, which will be described later. The core member 25 is mounted to the end member 10 by fastening this back plate 32 to the core member 25 and then connecting it to the visible surface 10b of the end member 10 with mounting screws (not shown) or the like.

[0037] The cross-sectional shape of this core material 25 is approximately L-shaped with a visible surface portion 25b and a visible surface portion 25c, and the reason for fixing it within the outdoor corner portion 10c of the end member 10 is to suppress heat transfer to the side of the approximately L-shaped cross-sectional shape of this core material 25 where the corner of the L is not located and the end portion faces. That is, by positioning the metal core material 25 inside the outdoor portion of the end member 10 and positioning the narrow end portion 25a of the visible surface portion 25b of the core material 25 inside the room, the heat transfer area of ​​the core material 25 to the indoor side is narrowed, suppressing heat transfer through the core material 25. Also, by positioning the indoor side end portion 25a of the core material 25 outside the room relative to the outdoor side end portion 9b1 of the visible surface portion 9b of the indoor side surface material 9, heat transfer between the core material 25 and the indoor side surface material 9 is suppressed, improving insulation.

[0038] The hinge 3 has a frame-side mounting plate 3a and a door-side mounting plate 3b. Reference numeral 28 denotes a hinge mounting screw that mounts the frame-side mounting plate 3a to the vertical frame 4. The hinge mounting screw 28 is passed through a through-hole provided in the door-side mounting plate 3a and the door-side visible surface 4m of the vertical frame 4, and is then screwed into a screw hole in a back plate 29 fixed within a core material 4k fixed within the hollow portion 4d, thereby fixing the frame-side mounting plate 3a to the vertical frame 4.

[0039] Reference numeral 31 denotes hinge mounting screws that secure the door body side mounting plate 3b to the door body 2. These hinge mounting screws 31 are passed through holes provided in the door body side mounting plate 3b, the visible surface portion 10b of the end member 10, and the core material 25, and some of the screws 31 are also passed through the visible surface portion 8b of the exterior surface material 8 of the door body 2 and are screwed into and fastened to screw holes in a back plate 32 that is attached to the back side of the core material 25, thereby securing the door body side mounting plate 3b to the door body 2.

[0040] Reference numeral 35 denotes a sealing material that closes the gap between the vertical frame 4 of the frame 1 and the door body 2, thereby supplementarily preventing the intrusion of outside air. This sealing material 35 is made of rubber or resin, and in this embodiment, a contact portion 35a of this sealing material 35 that contacts and bends against the door body 2 is formed by a fin. This sealing material 35 is fixed and attached to the visible surface portion 4m of the vertical frame 4 on the door body side with a fastener such as a rivet 36. When the door is closed, as shown in the figure, the contact portion 35a of the sealing material 35 contacts the exposed portion 10a of the visible surface of the end member 10, thereby sealing the gap between the vertical frame 4 and the door body 2. The blocking material 35 has an attachment portion 35b on the vertical frame 4 side. In this way, by abutting the abutting portion 35a of the sealing material 35 against the exposed portion 10a of the end member 10, the indoor surface material 9 of the door body 2 is blocked by the sealing material 35, so in addition to improving the airtightness by the airtight material 18, the thermal influence of the outside air on the indoor surface material 9 is reduced, improving the thermal insulation. When the door is closed, Airtight material 18 and Filler 3 to 5 Therefore, it is isolated from the outside and the inside (shielding) A region 60 is formed. Around the periphery of the region 60, the vertical frame 4 (frame body 1), the airtight material 18, the airtight material mounting portion 4g, the blocking material 35, and the end member 10 of the door body 2 are provided.

[0041] As described above, in this embodiment, as shown in Figures 2, 4 and 5, heat insulating materials 17k, 17m and 17n are provided in the end members 10, 12 and 13, respectively, thereby preventing convection due to the temperature difference between indoors and outdoors in each end member 10, 12 and 13, improving the heat insulating properties of the end members 10, 12 and 13 and improving the heat insulating properties of the door body 2.

[0042] In addition, in this embodiment, the end members 10, 12, and 13 are made of a resin material with high heat insulation properties, which can further improve the heat insulation properties.

[0043] When providing insulation within the end members 10, 12, and 13, the end of the panel-shaped insulation 17p to be placed within the surface members 8 and 9 may be fitted into the end members 10, 12, and 13, or a fluid insulation material may be injected to fill the end members 10, 12, and 13. However, as shown in this embodiment, by fitting block-shaped insulation materials 17k, 17m, and 17n, which are separate from the panel-shaped insulation material 17, into the end members 10, 12, and 13, respectively, the end members 10, 12, and 13 and the insulation material 17p can be assembled in separate processes, facilitating manufacture.

[0044] In the above embodiment, the end member 10 is formed hollow, which increases its strength. However, as shown in Fig. 6, the end member 10X on the hanging side may have a U-shaped cross section. In Fig. 6, the end member 10X has an outdoor corner portion 10X1 and an indoor corner portion 10X2.

[0045] The present invention has been described above using embodiments, but when implementing the present invention, materials and configurations other than those shown in the above embodiments can be used for the frame 1. In addition, when implementing the present invention, various changes and additions can be made to the components and their combinations within the scope of the gist of the present invention.
