戸先框１と吊元框２は、図２に示すように、アルミ形材よりなる框本体５ａ，５ｂと、框本体５ａ，５ｂの一方側及び他方側の見付面を被覆する表面材６ａ，６ｂとを有している。戸先框１と吊元框２は、見付寸法Ａが９４ｍｍである。框本体５ａ，５ｂは、一方側及び他方側の見付壁２４ａ，２４ｂと外周側及び内周側の見込壁２５ａ，２５ｂとで矩形の中空部が形成され、内周側の見込壁２５ｂの内周側にパネル保持片２６，２６が形成され、パネル保持片２６，２６にビード２７を介してパネル２０の側端部を保持してある。内周側の見込壁２５ｂは、見付壁２４ａ，２４ｂよりも一方側及び他方側に僅かに突出しており、パネル保持片２６，２６の見付面と見付壁２４ａ，２４ｂとの間に段部２８が形成されており、パネル保持片２６，２６の見付面と表面材６ａ，６ｂの表面が面一になっている。框本体５ａ，５ｂの外周側には溝２９が形成され、その溝２９は目板３０を取付けて塞いであり、側方から見て框本体５ａ，５ｂが目板３０で隠れている。
戸先框１及び吊元框２の上端及び下端の小口には、図４，５に示すように、小口キャップ７が裏板３１にネジ３２で取付けてある。小口キャップ７は、戸先框１及び吊元框２の框本体５ａ，５ｂのパネル保持片２６，２６を除いた部分の小口を覆っている。 As shown in FIG. 2, the door frame 1 and the suspension frame 2 are composed of frame bodies 5a and 5b made of aluminum profiles and surface materials covering one side and the other side of the frame bodies 5a and 5b. 6a and 6b. The door frame 1 and the hanging frame 2 have a width A of 94 mm. In the frame bodies 5a and 5b, a rectangular hollow portion is formed by the one side and the other side side walls 24a and 24b and the outer and inner side projection walls 25a and 25b. Panel holding pieces 26 , 26 are formed on the inner peripheral side, and side ends of the panel 20 are held by the panel holding pieces 26 , 26 via beads 27 . The projection wall 25b on the inner peripheral side protrudes slightly to one side and the other side from the mounting walls 24a, 24b, and is located between the mounting surfaces of the panel holding pieces 26, 26 and the mounting walls 24a, 24b. A stepped portion 28 is formed so that the facing surfaces of the panel holding pieces 26, 26 and the surfaces of the surface members 6a, 6b are flush with each other. A groove 29 is formed on the outer peripheral side of the frame bodies 5a and 5b, and the groove 29 is closed by attaching a panel 30 so that the frame bodies 5a and 5b are hidden by the panel 30 when viewed from the side.
As shown in FIGS. 4 and 5, the edge caps 7 are attached to the back plate 31 with screws 32 at the upper and lower ends of the door frame 1 and the suspension frame 2 . The edge cap 7 covers the edges of the frame bodies 5a and 5b of the door frame 1 and the hanging frame 2 except for the panel holding pieces 26 and 26.例文帳に追加

表面材６ａ，６ｂは、木の薄板（挽板）を使用しており、その厚さは２～２０ｍｍとしている。木の厚みを薄くすることで、木の変形を抑え、木の変形によるアルミ形材への負荷をかけないようにする効果がある。なお、本実施形態の室内ドアでは、表面材６ａ，６ｂの厚みを３ｍｍとしている。表面材６ａ，６ｂは、框本体５ａ，５ｂの見付面に框本体５ａ，５ｂ（アルミ）と表面材６ａ，６ｂ（木）の材質の違いによる伸び量の違いを吸収し得る接着剤８で取付けてある。このような接着剤８としては、弾性接着剤や弾性テープを用いることができる。弾性接着剤としては、シリコーン系、ウレタン系、アクリル系などが挙げられる。表面材６ａ，６ｂは、図４と図６（ａ）に示すように、長手方向の端部が框本体５ａ，５ｂの小口より上下にはみ出しており、小口キャップ７は表面材６ａ，６ｂで隠れている。また表面材６ａ，６ｂは、図２に示すように、外周側の幅方向の端面３３がフリーになっており、内周側の幅方向の端面３４は框本体５ａ，５ｂの段部２８との間に隙間を設けてある。 The surface materials 6a and 6b are thin wooden boards (sawn boards) with a thickness of 2 to 20 mm. By reducing the thickness of the wood, it has the effect of suppressing the deformation of the wood and not applying a load to the aluminum shape due to the deformation of the wood. In addition, in the interior door of this embodiment, the surface members 6a and 6b have a thickness of 3 mm. The surface materials 6a and 6b are applied with an adhesive 8 on the facing surfaces of the frame bodies 5a and 5b, which can absorb the difference in elongation due to the difference in material between the frame bodies 5a and 5b (aluminum) and the surface materials 6a and 6b (wood). installed with As such an adhesive 8, an elastic adhesive or an elastic tape can be used. Examples of elastic adhesives include silicone-based, urethane-based, and acrylic-based adhesives. As shown in FIGS. 4 and 6(a), the surface materials 6a and 6b have longitudinal ends protruding vertically from the edges of the frame bodies 5a and 5b. hidden. As shown in FIG. 2, the surface members 6a and 6b are free at the outer peripheral width direction end faces 33, and the inner peripheral width direction end faces 34 are formed from the stepped portions 28 of the frame bodies 5a and 5b. There is a gap between

上框３と下框４は、図１に示すように、アルミ形材のみからなり、表面材を有していない。上框３と下框４は、見付寸法Ｂが２８ｍｍと、戸先框１及び吊元框２の見付寸法（９４ｍｍ）の半分以下（実施形態のものは１／３以下）としてある。上框３と下框４は、中空部３５と、中空部３５の内周側に設けたパネル保持部３６を有し、パネル保持部３６にビード２７を介してパネル２０の上下端部を保持してある。中空部３５の外周側の見込壁３７は、見付壁３８，３８よりも見込方向に突出している。中空部３５の内周側の見込壁には、タッピングホール３９が設けてある。上框３と下框４は、図５に示すように、長手方向の端部が垂直に切断され、切断した小口を縦框（戸先框１及び吊元框２）の内周側面４０に当接し（縦框１，２のパネル保持片２６，２６は、上框１及び下框２と干渉しないように上下端部を一部切除してある）、縦框１，２の外周側から挿入したネジ４１（図２参照）をタッピングホール３９に捩じ込むことで、縦横の框１，２，３，４を連結している。図４，５に示すように、小口キャップ７は、縦框１，２のパネル保持片２６，２６の小口を隠す部分を有していないが、横框（上框３と下框４）の外周側の見込壁３７が見付壁３８，３８より見込方向に突出していることで、小口キャップ７が無い部分を隠すことができる。 As shown in FIG. 1, the upper frame 3 and the lower frame 4 are made of only aluminum profiles and have no surface material. The upper stile 3 and the lower stile 4 have an overall size B of 28 mm, which is less than half (1/3 or less in the embodiment) of the overall size (94 mm) of the door frame 1 and the suspension base frame 2 . The upper frame 3 and the lower frame 4 each have a hollow portion 35 and a panel holding portion 36 provided on the inner peripheral side of the hollow portion 35. The upper and lower ends of the panel 20 are held by the panel holding portion 36 via beads 27. I have A projection wall 37 on the outer peripheral side of the hollow portion 35 protrudes further in the projection direction than the projection walls 38 , 38 . A tapping hole 39 is provided in the projection wall on the inner peripheral side of the hollow portion 35 . As shown in FIG. 5, the upper frame 3 and the lower frame 4 are vertically cut at their ends in the longitudinal direction, and the cut edge is attached to the inner peripheral side 40 of the vertical frame (door frame 1 and hanging frame 2). abut (the panel holding pieces 26, 26 of the vertical frames 1, 2 are partly cut off at the upper and lower ends so as not to interfere with the upper frame 1, the lower frame 2), By screwing the inserted screws 41 (see FIG. 2) into the tapping holes 39, the vertical and horizontal frames 1, 2, 3 and 4 are connected. As shown in FIGS. 4 and 5, the edge cap 7 does not have a portion that hides the edges of the panel holding pieces 26, 26 of the vertical frames 1, 2, but the horizontal frames (upper frame 3 and lower frame 4) Since the projection wall 37 on the outer peripheral side protrudes in the projection direction from the attachment walls 38, 38, the part without the edge cap 7 can be hidden.

図６は、戸先框（縦框）１の上端部を拡大した側面図であって、図６（ａ）が通常状態、図６（ｂ）は框本体５ａが熱伸びした状態を示している。同図に示すように、日射等で暖められるとアルミ形材よりなる框本体５ａは熱伸びし、木の薄板よりなる表面材６ａはほとんど伸びないが、接着剤８がその伸び量の違いを吸収する。そして、図６（ａ）に示すように、表面材６ａの長手方向端部を框本体５ａの小口からはみ出させ、小口キャップ７を表面材６ａで隠しておくことで、図６（ｂ）に示すように、框本体５ａが熱伸びしても框本体５ａの端部と小口キャップ７が表面材６ａからはみ出さない。この点は、吊元框（縦框）２についても同様である。 FIG. 6 is an enlarged side view of the upper end of the door frame (vertical frame) 1. FIG. 6(a) shows a normal state, and FIG. 6(b) shows a state where the frame body 5a is thermally stretched. there is As shown in the figure, when heated by the sun, the frame main body 5a made of an aluminum profile thermally expands, while the surface material 6a made of a thin wooden plate hardly expands. Absorb. Then, as shown in FIG. 6(a), the longitudinal end portion of the surface material 6a is protruded from the edge of the frame body 5a, and the edge cap 7 is hidden by the surface material 6a, resulting in FIG. 6(b). As shown, even if the frame main body 5a is thermally stretched, the ends of the frame main body 5a and the edge cap 7 do not protrude from the surface material 6a. This point is the same for the hanging frame (vertical frame) 2 as well.

また本室内ドアは、表面材６ａ，６ｂの幅方向の端面３３，３４が框本体５ａ，５ｂとの間に隙間が設けてあるかフリーになっていることで、框本体５ａ，５ｂと表面材６ａ，６ｂとを弾性接着剤８で接着したことと相まって、框本体５ａ，５ｂは表面材６ａ，６ｂに拘束されることなく伸び縮みでき、框１，２に反りが生じたり表面材６ａ，６ｂに亀裂が生じたりするのを防止できる。 In the main interior door, the width direction end surfaces 33 and 34 of the surface materials 6a and 6b are provided with gaps or are free from the frame bodies 5a and 5b, so that the frame bodies 5a and 5b and the surface Since the members 6a and 6b are bonded together with the elastic adhesive 8, the frame bodies 5a and 5b can expand and contract without being restrained by the surface members 6a and 6b. , 6b can be prevented from being cracked.

縦框（戸先框１及び吊元框２）と横框（上框３及び下框４）の両方に表面材が取付けてあったとすると、縦框１，２の框本体５ａ，５ｂ及び横框３，４が熱伸びしたときに縦框１，２の表面材６ａ，６ｂと横框３，４の表面材との間に隙間が開く問題があるが、本室内ドアは、縦框１，２のみに表面材６ａ，６ｂが取付けてあり、横框３，４には表面材が取付けてないため、そのような問題を払拭できる。横框３，４は、ドアの上端部と下端部に位置し、もともと目立たない上、横框３，４の見付寸法Ｂを縦框１，２の見付寸法Ａの半分以下とすることで、横框３，４が一層目立たなくなっているため、横框３，４に表面材がなくても特に違和感がなく、見付寸法が大きく、手で触れられることの多い縦框１，２が木の薄板よりなる表面材６ａ，６ｂで被覆してあることで、木の暖かみや触感の柔らかさを十分に享受できる。 If the surface material is attached to both the vertical frame (door frame 1 and hanging frame 2) and the horizontal frame (upper frame 3 and lower frame 4), the frame bodies 5a and 5b of the vertical frames 1 and 2 and the horizontal There is a problem that a gap opens between the surface materials 6a and 6b of the vertical frames 1 and 2 and the surface materials of the horizontal frames 3 and 4 when the frames 3 and 4 thermally expand. , 2 are attached with the surface members 6a and 6b, and the horizontal rails 3 and 4 are not attached with the surface members, so that such a problem can be eliminated.
