The end member is made of a resin material and is made of a resin material.
Among the end members having a hollow cross-sectional shape, at least a part of the end members is provided with a heat insulating material.

また、本発明のドアは、前記ドアにおいて、
前記室外側表面材と前記室内側表面材との間の断熱材がパネル状をなし、前記端部材内の断熱材が、前記断熱パネルと別体のブロック状をなすことを特徴とする。 Further, the door of the present invention is the door.
The heat insulating material between the outdoor side surface material and the indoor side surface material has a panel shape, and the heat insulating material inside the end member has a block shape separate from the heat insulating panel.

本発明においては、ドア本体の四周の端部材のうち、断面形状が中空形状をなす端部材のうちの少なくとも一部の内部に断熱材を設けたので、端部材内での室内外温度差による対流が防止され、断熱性の高いドアが提供できる。 In the present invention, since the heat insulating material is provided inside at least a part of the end members having a hollow cross section among the four peripheral end members of the door body, it depends on the indoor / outdoor temperature difference in the end members. Convection is prevented and a door with high heat insulation can be provided.

また、本発明において、端部材を樹脂製材料によって構成することにより、ドア本体の断熱性がさらに向上する。 Further, in the present invention, by forming the end member with a resin material, the heat insulating property of the door body is further improved.

また、本発明において、室外側表面材と室内側表面材との間の断熱材が断熱パネルでなり、前記端部材内の断熱材は、前記断熱パネルと別体の断熱ブロックでなる構成とすることにより、一枚の断熱パネルの端部を端部材内に配置する構造とする場合や、断熱材原料の注入、充填による工程によってドア本体を製造する場合に比較し、製造が容易となる。 Further, in the present invention, the heat insulating material between the outdoor surface material and the indoor surface material is a heat insulating panel, and the heat insulating material in the end member is composed of a heat insulating block separate from the heat insulating panel. As a result, the production becomes easier as compared with the case where the end portion of one heat insulating panel is arranged in the end member, or the case where the door body is manufactured by the process of injecting and filling the heat insulating material raw material.

Is used.

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の室外側コーナー部内に配置される。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 hanging side will be described with reference to FIG. Reference numeral 25 denotes a core material made of a metal such as a steel material that reinforces the hanging side of the door body 2. The core member 25 has an L-shaped cross section and is arranged in the outdoor corner portion of the hollow end member 10. Reference numeral 32 denotes a back plate for connecting to the mounting plate 3b of the hinge 3 described later, and the core material 25 is attached to the end member 10 with the back plate 32 fixed to the core material 25. 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Ｌ字形とし、これを端部材１０の室外側コーナー部内に固定している理由は、この芯材２５による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 reason why the cross-sectional shape of the core material 25 is L-shaped and this is fixed in the outdoor corner portion of the end member 10 is to suppress heat transfer by the core material 25. That is, by locating the metal core material 25 inside the outdoor side of the end member 10 and locating the narrow end portion 25a of the core material 25 on the indoor side, the heat transfer area of the core material 25 to the indoor side. Is narrowed to suppress heat transfer by the core material 25. Further, by locating the indoor side end portion 25a of the core material 25 to the outdoor side of the outdoor side end portion 9b1 of the prospective surface portion 9b of the indoor side surface material 9, between the core material 25 and the indoor side surface material 9. It 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 body side mounting plate 3a and a door body side mounting plate 3b. Reference numeral 28 denotes a hinge mounting screw for mounting the frame body side mounting plate 3a to the vertical frame 4. The screw 28 for attaching the hinge is passed through the door body side mounting plate 3a and the through hole provided in the door body side prospective surface portion 4m of the vertical frame 4, and the back surface fixed in the core material 4k fixed in the hollow portion 4d. The frame body side mounting plate 3a is fixed to the vertical frame 4 by screwing and fastening to the screw holes of the plate 29.

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. The screws 31 for attaching the hinges are passed through the door body side mounting plate 3b, the prospective surface portion 10b of the end member 10, and the through holes provided in the core material 25, and some of the screws 31 are on the outdoor surface of the door body 2. The door body side mounting plate 3b is fixed to the door body 2 by passing through the prospective surface portion 8b of the material 8 and screwing and fastening the screw holes of the back plate 32 which is applied to the back side of the core material 25.

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。 Reference numeral 35 denotes a closing material that closes the gap between the vertical frame 4 of the frame body 1 and the door body 2 to assist the intrusion of outside air. The closing material 35 is made of rubber or resin, and in the present embodiment, the contact portion 35a that abuts and bends against the door body 2 of the closing material 35 is formed of fins. The closing material 35 is fixed and attached to the door body side prospective surface portion 4 m of the vertical frame 4 with a fixing tool such as a rivet 36. In the state where the door is closed, as shown in the drawing, the contact portion 35a of the closing member 35 contacts the exposed portion 10a of the prospective surface of the end member 10 to close the gap between the vertical frame 4 and the door body 2. .. In this way, by bringing the contact portion 35a of the closing material 35 into contact with the exposed portion 10a of the end member 10, the indoor surface material 9 of the door body 2 is blocked by the closing material 35, so that the airtight material 18 is used. In addition to improving the airtightness, the thermal influence of the outside air on the indoor surface material 9 is reduced, and the heat insulating property is improved.

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 the present embodiment, as shown in FIGS. 2, 4, and 5, heat insulating materials 17k, 17m, and 17n are provided in the end members 10, 12, and 13, respectively, so that each end is provided. Convection due to indoor / outdoor temperature difference in the members 10, 12 and 13 is prevented, the heat insulating property of the end members 10, 12 and 13 is improved, and the heat insulating property 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。 Further, in the present embodiment, since the end members 10, 12, and 13 are made of a resin material having high heat insulating properties, the heat insulating 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 and 13, the end portion of the panel-shaped heat insulating material 17p to be arranged in the surface materials 8 and 9 is arranged so as to be fitted in the end members 10, 12 and 13. Alternatively, the end members 10, 12 and 13 may be filled by injecting a heat insulating material having fluidity. However, as shown in the present embodiment, the block-shaped heat insulating materials 17k, 17m, and 17n, which are 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, and the production becomes easy.

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。 In the above embodiment, since the end member 10 is formed in a hollow shape, the strength can be increased. However, as shown in FIG. 6, the end member 10X on the hanging side may have a U-shaped cross section.

以上本発明を実施の形態により説明したが、本発明を実施する場合、枠体１としては上記実施の形態で示したもの以外の素材、構成のものを用いることができる。その他、本発明を実施する場合、本発明の要旨を逸脱しない範囲において、構成部材やその組み合わせについて、種々の変更、付加が可能である。 Although the present invention has been described above according to the embodiment, when the present invention is carried out, a material and a structure other than those shown in the above embodiment can be used as the frame body 1. In addition, when the present invention is carried out, various changes and additions can be made to the constituent members and their combinations without departing from the gist of the present invention.
