しかしながら、特許文献１に記載されているように、金属製の框や補強材を設けた従来のドアは、熱伝導性の高い框や補強材を通して、外気と内気との間の熱伝導が起こり、このことが断熱性の向上を妨げるという問題点がある。また、図１１に示した構造の従来のドアは、塞ぎ材５８が鋼板製の室内側表面材５６の見込み面部５６ｂに当接しているので、室内側表面材５６の見込み面部５６ｂの室外側の部分は外気に曝されており、樹脂に比較して熱伝導姓の高い鋼板製の室内側表面材５６を通して外気と内気との間の熱伝導が起こるので、この構造もやはり断熱性の向上の妨げになっているという問題点がある。 However, as described in Patent Document 1, in a conventional door provided with a metal frame and a reinforcing material, heat conduction between the outside air and the inside air occurs through the frame and the reinforcing material having high thermal conductivity. However, there is a problem in that this hinders the improvement of heat insulation. Further, in the conventional door having the structure shown in FIG. 11, since the closing member 58 is in contact with the prospective surface portion 56b of the indoor surface member 56 made of a steel plate, the prospective surface portion 56b of the indoor surface member 56 is exposed outside the room. The part is exposed to the outside air, and heat conduction occurs between the outside air and the inside air through the indoor surface material 56 made of a steel plate, which has a higher heat conduction than the resin, so that this structure also improves the heat insulating property. There is a problem that it is an obstacle.

The hinge mounting screw 31 is passed through the door body side mounting plate 3b and through holes provided in the end member 10 and the core member 25, and some of the screws 31 are prospective surface portions of the outdoor surface member 8 of the door body 2. The door main body side mounting plate 3b is fixed to the door main body 2 by also passing through 8b and screwing it into the screw hole of the back plate 32 applied to the back side of the core material 25 and fastening. A spacer 33 is interposed between the door body side mounting plate 3b and the door body 2 to adjust the installation of the door body 2.

３５は枠体１の縦枠４とドア本体２との間の隙間を閉塞する塞ぎ材である。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に接して撓む撓み部３５ａがひれ部によって構成されている例を示しているが、撓み部が中空状に形成されたものであってもよい。この塞ぎ材３５は、縦枠４のドア本体側プレート部４ｄ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の撓み部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。 Reference numeral 35 is a closing member that closes a gap between the vertical frame 4 of the frame body 1 and the door body 2. The closing member 35 is made of rubber or resin, and in the present embodiment, an example is shown in which the bending portion 35a of the closing member 35 that bends in contact with the door body 2 is formed by a fin portion. However, the bending portion may be formed in a hollow shape. The closing member 35 is fixed and attached to the door body side plate portion 4d of the vertical frame 4 by a fixing tool such as a rivet 36. In the closed state of the door, as shown in the figure, the bending portion 35a of the closing member 35 abuts on 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.

このように、本実施の形態においては、ドア本体２に備える樹脂製の端部材１０の見込み面部に、枠体１に対して露出した露出部１０ａを設け、その露出部１０ａに、枠体１に取付けた塞ぎ材３５を当接させて枠体１とドア本体２との間の隙間を閉塞したので、ドア本体２の室内側表面材９は塞ぎ材３５により外気と遮断される。このため、室内側表面材９が外気によって熱的に影響される度合が軽減され、断熱性が向上する。 As described above, in the present embodiment, the exposed portion 10a exposed to the frame body 1 is provided on the prospective surface portion of the resin-made end member 10 included in the door body 2, and the frame body 1 is provided on the exposed portion 10a. Since the closing member 35 attached to the door is brought into contact with the opening to close the gap between the frame body 1 and the door body 2, the inside surface material 9 of the door body 2 is blocked from the outside air by the closing member 35. Therefore, the degree to which the indoor surface material 9 is thermally affected by the outside air is reduced, and the heat insulating property is improved.

なお、端部材１０の露出部１０ａは必ずしも枠体１側に突出していなくても断熱性の向上は達成できるが、しかし露出部１０ａを突出させることにより、露出部１０ａが室外側表面材８の見込み面部８ｂの端部や室内側表面材９の見込み面部９ｂの端部の目隠しとなり、外観が向上するという利点がある。 Although the exposed portion 10a of the end member 10 does not necessarily have to project to the frame 1 side, the heat insulation can be improved, but by making the exposed portion 10a project, the exposed portion 10a is covered with the outdoor surface material 8. There is an advantage that the end portion of the prospective surface portion 8b and the end portion of the prospective surface portion 9b of the indoor-side surface material 9 are blinded and the appearance is improved.

本発明を実施する場合、金属製の芯材２５の室内側端部は、室内側表面材９の見込み面部９ｂの室外側端部よりも室内側に位置させてもよいが、本実施の形態のように、芯材２５の室内側端部を、室内側表面材９の見込み面部９ｂの室外側端部よりも室外側に位置させて構成することによって、芯材２５と室内側表面材９との間の熱伝導が低減され、より断熱性が向上する。 In the case of carrying out the present invention, the indoor side end of the metal core material 25 may be located on the indoor side with respect to the outdoor side end of the prospective surface portion 9b of the indoor surface material 9, but the present embodiment is not limited thereto. As described above, by arranging the indoor side end portion of the core material 25 to be located outside the outdoor side end of the prospective surface portion 9b of the indoor side surface material 9, the core material 25 and the indoor side surface material 9 are formed. The heat conduction between and is reduced, and the heat insulation is further improved.

また、本発明を実施する場合、芯材２５に固定する樹脂製芯材２６は必ずしも必要ではないが、樹脂製芯材２６を金属製芯材２５と並設して端部材１０内に収容することにより、ドア本体２の強度が増大すると共に、断熱性が向上する。 Further, when the present invention is carried out, the resin core material 26 fixed to the core material 25 is not always necessary, but the resin core material 26 is arranged in parallel with the metal core material 25 and accommodated in the end member 10. As a result, the strength of the door body 2 is increased and the heat insulating property is improved.

本実施の形態においては、塞ぎ材３５を端部材１０の露出部１０ａに当接させる構造は、ドア本体２の吊元側のみに適用しており、吊元側は、蝶番３を設ける必要から、枠体１とドア本体２との間の隙間が大きくする必要があるから、吊元側に本実施の形態のような構造を採用することが、断熱性向上効果を得る上で重要となる。しかしながら、このような塞ぎ材３５を露出部１０ａに当接させる構造は、戸先側あるいは上枠側において、枠体１とドア本体２との間の隙間が大きい場合には、戸先側あるいは上枠側や下枠側に設けてもよい。 In the present embodiment, the structure in which the blocking member 35 is brought into contact with the exposed portion 10a of the end member 10 is applied only to the suspension base side of the door body 2, and the hinge 3 must be provided on the suspension base side. Since it is necessary to increase the gap between the frame body 1 and the door body 2, it is important to adopt the structure of the present embodiment on the hanging side in order to obtain the effect of improving heat insulation. .. However, such a structure in which the blocking member 35 is brought into contact with the exposed portion 10a has a structure in which the gap between the frame body 1 and the door body 2 on the door tip side or the upper frame side is large when the door tip side or It may be provided on the upper frame side or the lower frame side.

Are configured so that the positions of the screw holes 39a of the back plate 39 are matched.

図６に示すように芯材２５Ｘ、断熱材３８、裏板３９を構成すれば、芯材２５Ｘの断熱性が向上する。また、芯材２５Ｘに対して断熱材３８を嵌合して配置するだけで、裏板３９のねじ孔３９ａの位置を、芯材２５Ｘの貫通孔２５ｃの位置に合わせることができ、製造が容易となる。なお、芯材２５Ｘの断面形状は、図６に示したコ字形のみに限られず、ホロ−（中空）形状としてもよい。 If the core member 25X, the heat insulating member 38, and the back plate 39 are configured as shown in FIG. 6, the heat insulating property of the core member 25X is improved. Further, the position of the screw hole 39a of the back plate 39 can be aligned with the position of the through hole 25c of the core member 25X only by fitting and disposing the heat insulating member 38 in the core member 25X, which facilitates manufacturing.
