Use

次にドア本体2の吊元側の取付け構造について、図2により説明する。25はドア本体2の吊元側を補強する鋼材等の金属でなる芯材である。この芯材25は断面形状がL字形をなし、中空状の端部材10の内部であって、室内外方向において、室外側コーナー部10cと室内側コーナー部10dとの間に配置される。32は後述の蝶番3の取付け板3bに結合するための裏板であり、芯材25の端部材10への取付けは、この裏板32を芯材25に固定した状態で、端部材10の見込み面部10bに対し、不図示の取付けねじ等により結合して行なう。 Next, the mounting structure of the door body 2 on the suspension side will be described with reference to FIG. Reference numeral 25 denotes a core material made of metal such as steel for reinforcing the hanger side of the door body 2 . The core member 25 has an L-shaped cross section and is arranged inside the hollow end member 10 between the outdoor corner portion 10c and the indoor inner corner portion 10d in the indoor-outdoor direction. Reference numeral 32 denotes a back plate for connecting to the mounting plate 3b of the hinge 3, which will be described later. It is connected to the prospective surface portion 10b with a mounting screw (not shown) or the like.

この芯材25の断面形状を見込み面部25bと見付け面部25cを備えた略L字形とし、これを端部材10の室外側コーナー部10c内に固定している理由は、この芯材25によるその断面形状の略L字形におけるLの字の角がなく端部が向いている側への伝熱を抑えるためである。すなわち金属製の芯材25を端部材10の室外側の内部に位置させ、芯材25の見込み面部25bの狭幅の端部25aを室内側に位置させることにより、芯材25の室内側への伝熱面積を狭くして芯材25による伝熱を抑制している。また、芯材25の室内側端部25aを、室内側表面材9の見込み面部9bの室外側端部9b1よりも室外側に位置させることにより、芯材25と室内側表面材9との間の伝熱を抑制し、断熱性を高めている。 The core material 25 has a substantially L-shaped cross-sectional shape with a projected surface portion 25b and a facing surface portion 25c. This is for suppressing heat transfer to the side of the substantially L-shaped shape, where the end of the L-shape has no corners and faces. That is, by positioning the metallic core member 25 inside the end member 10 on the outdoor side and positioning the narrow end portion 25a of the projected surface portion 25b of the core member 25 on the indoor side, the core member 25 is moved to the indoor side. The heat transfer area of is narrowed to suppress heat transfer by the core material 25 . Further, by positioning the indoor-side end portion 25a of the core material 25 on the outdoor side of the outdoor-side end portion 9b1 of the projected surface portion 9b of the indoor-side surface member 9, the gap between the core material 25 and the indoor-side surface member 9 suppresses heat transfer and enhances heat insulation.

蝶番3は枠体側取付け板3aとドア本体側取付け板3bとを有する。28は枠体側取付け板3aを縦枠4に取付ける蝶番取付け用のねじである。この蝶番取付け用のねじ28を、ドア本体側取付け板3aと、縦枠4のドア本体側見込み面部4mに設けた貫通孔に通し、中空部4d内に固定した芯材4k内に固定した裏板29のねじ孔に螺合し締結することにより、枠体側取付け板3aを縦枠4に固定する。 The hinge 3 has a frame side mounting plate 3a and a door body side mounting plate 3b. Reference numeral 28 denotes hinge mounting screws for mounting the frame side mounting plate 3a to the vertical frame 4. As shown in FIG. This hinge mounting screw 28 is passed through the door main body side mounting plate 3a and through holes provided in the door main body side projection surface portion 4m of the vertical frame 4, and is fixed in the core material 4k fixed in the hollow portion 4d. The frame-side mounting plate 3a is fixed to the vertical frame 4 by screwing it into the screw hole of the plate 29 and fastening it.

31はドア本体側取付け板3bをドア本体2に固定する蝶番取付け用のねじである。この蝶番取付け用のねじ31を、ドア本体側取付け板3bと、端部材10の見込み面部10bおよび芯材25に設けた貫通孔に通し、一部のねじ31についてはドア本体2の室外側表面材8の見込み面部8bにも通し、芯材25の裏側に当てた裏板32のねじ孔に螺合し締結することにより、ドア本体側取付け板3bをドア本体2に固定する。 Reference numeral 31 denotes a hinge mounting screw for fixing the door body side mounting plate 3b to the door body 2. As shown in FIG. The screws 31 for mounting the hinge are passed through the through holes provided in the door body side mounting plate 3b, the projected surface portion 10b of the end member 10, and the core member 25. The mounting plate 3b on the door body side is fixed to the door body 2 by passing it through the projected surface portion 8b of the member 8 and screwing it into the screw hole of the back plate 32 which is in contact with the back side of the core member 25 and tightening.

35は枠体1の縦枠4とドア本体2との間の隙間を閉塞して外気の侵入を補助的に抑える塞ぎ材である。この塞ぎ材35はゴムまたは樹脂製のものであり、本実施の形態においては、この塞ぎ材35のドア本体2に当接して撓む当接部35aがヒレによって構成されている。この塞ぎ材35は、縦枠4のドア本体側見込み面部4mにリベット36等の固定具により固定して取付ける。ドアを閉めた状態においては、図示のように、塞ぎ材35の当接部35aが端部材10の見込み面の露出部10aに当接して縦枠4とドア本体2との間の隙間を塞ぐ。このように、端部材10の露出部10aに塞ぎ材35の当接部35aを当接させることにより、ドア本体2の室内側表面材9は塞ぎ材35によって遮断されるので、気密材18による気密性の向上に加え、室内側表面材9の外気による熱的影響が軽減され、断熱性が向上する。 A closing member 35 blocks the gap between the vertical frame 4 of the frame 1 and the door body 2 to assist in preventing outside air from entering. The closing member 35 is made of rubber or resin, and in the present embodiment, a contact portion 35a of the closing member 35 which contacts the door body 2 and bends is formed of a fin. The closing member 35 is fixed and attached to the door main body side projection surface portion 4m of the vertical frame 4 with a fixture such as a rivet 36 or the like. When the door is closed, the contact portion 35a of the closing member 35 contacts the exposed portion 10a of the projection surface of the end member 10 to close the gap between the vertical frame 4 and the door body 2, as shown in the drawing. . By bringing the abutting portion 35a of the closing member 35 into contact with the exposed portion 10a of the end member 10 in this manner, the indoor surface member 9 of the door body 2 is blocked by the closing member 35, so that the airtight member 18 does not In addition to improving the airtightness, the thermal influence of the outside air on the room-side surface material 9 is reduced, thereby improving the heat insulation.

上述したように、本実施の形態においては、図2、図4、図5に示したように、端部材10,12,13内にそれぞれ断熱材17k,17m,17nを設けたので、各端部材10,12,13内における室内外温度差による対流が防止され、端部材10,12,13における断熱性が向上し、ドア本体2の断熱性が向上する。 As described above, in this embodiment, as shown in FIGS. Convection due to the indoor-outdoor temperature difference in the members 10, 12, 13 is prevented, the heat insulation of the end members 10, 12, 13 is improved, and the heat insulation of the door body 2 is improved.

また、本実施の形態においては、端部材10,12,13に断熱性の高い樹脂製材料を用いているので、さらに断熱性を向上させることができる。 Moreover, in the present embodiment, the end members 10, 12, 13 are made of a resin material having high heat insulation properties, so that the heat insulation properties can be further improved.

端部材10,12,13内に断熱材を設ける場合、表面材8,9内に配置するパネル状の断熱材17pの端部を端部材10,12,13内に嵌め込んだ形で配置したり、流動性を有する断熱材を注入することによって端部材10,12,13内に充填してもよい。しかしながら、本実施の形態で示したように、端部材10,12,13内にパネル状の断熱材17とは別体をなすブロック状の断熱材17k,17m,17nをそれぞれ嵌め込むことによって配置することにより、端部材10,12,13と断熱材17pをそれぞれ別工程で組み立てることができ、製作が容易となる。 When the heat insulating material is provided in the end members 10, 12, 13, the end portions of the panel-shaped heat insulating material 17p arranged in the surface members 8, 9 are fitted in the end members 10, 12, 13. Alternatively, the end members 10, 12, 13 may be filled by injecting a heat insulating material having fluidity. However, as shown in the present embodiment, block-shaped heat insulating materials 17k, 17m, and 17n separate from the panel-shaped heat insulating material 17 are fitted into the end members 10, 12, and 13, respectively. By doing so, the end members 10, 12, 13 and the heat insulating material 17p can be assembled in separate processes, which facilitates manufacture.

上記実施の形態においては、端部材10を中空状に形成したので、強度を高めることができる。しかしながら、図6に示すように、吊元側の端部材10Xは、コ字形の断面形状としても良い。図6において、端部材10Xは室外側コーナー部10X1と、室内側コーナー部10X2を備える。 In the above embodiment, since the end member 10 is hollow, the strength can be increased. However, as shown in FIG. 6, the suspension-side end member 10X 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.

この芯材25の断面形状を見込み面部25bと見付け面部25cを備えた略L字形とし、これを端部材10の室外側コーナー部10c内に固定している理由は、この芯材25によるその断面形状の略L字形におけるLの字の角がなく端部が向いている側への伝熱を抑えるためである。すなわち金属製の芯材25を端部材10の室外側の内部に位置させ、芯材25の見込み面部25bの狭幅の端部25aを室内側に位置させることにより、芯材25の室内側への伝熱面積を狭くして芯材25による伝熱を抑制している。また、芯材25の室内側端部25aを、室内側表面材9の見込み面部9bの室外側端部9b1よりも室外側に位置させることにより、芯材25と室内側表面材9との間の伝熱を抑制し、断熱性を高めている。 The core material 25 has a substantially L-shaped cross-sectional shape with a projected surface portion 25b and a facing surface portion 25c. This is for suppressing heat transfer to the side of the substantially L-shaped shape, where the end of the L-shape has no corners and faces. That is, by positioning the metallic core member 25 inside the end member 10 on the outdoor side and positioning the narrow end portion 25a of the projected surface portion 25b of the core member 25 on the indoor side, the core member 25 is moved to the indoor side. The heat transfer area of is narrowed to suppress heat transfer by the core material 25 . Further, by positioning the indoor-side end portion 25a of the core material 25 on the outdoor side of the outdoor-side end portion 9b1 of the projected surface portion 9b of the indoor-side surface member 9, the gap between the core material 25 and the indoor-side surface member 9 suppresses heat transfer and enhances heat insulation.

The closing member 35 is made of rubber or resin, and in the present embodiment, a contact portion 35a of the closing member 35 which contacts the door body 2 and bends is formed of a fin. The closing member 35 is fixed and attached to the door main body side projection surface portion 4m of the vertical frame 4 with a fixture such as a rivet 36 or the like. When the door is closed, the contact portion 35a of the closing member 35 contacts the exposed portion 10a of the projection surface of the end member 10 to close the gap between the vertical frame 4 and the door body 2, as shown in the drawing. . By bringing the abutting portion 35a of the closing member 35 into contact with the exposed portion 10a of the end member 10 in this manner, the indoor surface member 9 of the door body 2 is blocked by the closing member 35, so that the airtight member 18 does not In addition to improving the airtightness, the thermal influence of the outside air on the room-side surface material 9 is reduced, thereby improving the heat insulation. As shown in FIGS. 2 and 6, the airtight material 18, the closing material 35 and the door body 2 form an area 60 that is isolated from the outside and the inside.

上述したように、本実施の形態においては、図2、図4、図5に示したように、端部材10,12,13内にそれぞれ断熱材17k,17m,17nを設けたので、各端部材10,12,13内における室内外温度差による対流が防止され、端部材10,12,13における断熱性が向上し、ドア本体2の断熱性が向上する。 As described above, in this embodiment, as shown in FIGS. Convection due to the indoor-outdoor temperature difference in the members 10, 12, 13 is prevented, the heat insulation of the end members 10, 12, 13 is improved, and the heat insulation of the door body 2 is improved.

また、本実施の形態においては、端部材10,12,13に断熱性の高い樹脂製材料を用いているので、さらに断熱性を向上させることができる。 Moreover, in the present embodiment, the end members 10, 12, 13 are made of a resin material having high heat insulation properties, so that the heat insulation properties can be further improved.

端部材10,12,13内に断熱材を設ける場合、表面材8,9内に配置するパネル状の断熱材17pの端部を端部材10,12,13内に嵌め込んだ形で配置したり、流動性を有する断熱材を注入することによって端部材10,12,13内に充填してもよい。しかしながら、本実施の形態で示したように、端部材10,12,13内にパネル状の断熱材17とは別体をなすブロック状の断熱材17k,17m,17nをそれぞれ嵌め込むことによって配置することにより、端部材10,12,13と断熱材17pをそれぞれ別工程で組み立てることができ、製作が容易となる。 When the heat insulating material is provided in the end members 10, 12, 13, the end portions of the panel-shaped heat insulating material 17p arranged in the surface members 8, 9 are fitted in the end members 10, 12, 13. Alternatively, the end members 10, 12, 13 may be filled by injecting a heat insulating material having fluidity. However, as shown in the present embodiment, block-shaped heat insulating materials 17k, 17m, and 17n separate from the panel-shaped heat insulating material 17 are fitted into the end members 10, 12, and 13, respectively. By doing so, the end members 10, 12, 13 and the heat insulating material 17p can be assembled in separate processes, which facilitates manufacture.

上記実施の形態においては、端部材10を中空状に形成したので、強度を高めることができる。しかしながら、図6に示すように、吊元側の端部材10Xは、コ字形の断面形状としても良い。図6において、端部材10Xは室外側コーナー部10X1と、室内側コーナー部10X2を備える。 In the above embodiment, since the end member 10 is hollow, the strength can be increased.
