【発明の属する技術分野】
本発明は、引き違い障子等の障子下框から垂下片を垂下させ、この垂下片を下枠上面略フラットの下枠上面に形成したスライド溝に嵌入させた構造の障子下框クラッドサッシ構造に関する。
【0002】
【発明が解決しようとする課題】
本願出願人は、下枠上面を略フラットに形成したバリアフリーサッシ構造を検討するに当り、引き違い障子の外障子下框からは、その室内側よりから垂下片を垂下させ、内障子下框からは、その室外側よりから垂下片を垂下させ、一方、下枠上面には、これらの垂下片を嵌入スライドさせるスライド溝を形成した下枠構造を検討した。
このようなバリアフリーサッシ構造においても、断熱サッシ仕様に対する要求が高い。
【0003】
障子下框等にアルミサッシ等の金属製サッシを用いた場合に、上記外障子の垂下片をアルミ等で形成すると、室内側にアルミ等の金属面が露出して断熱性が劣り、結露も生じやすくなる。
一方、垂下片等を樹脂で形成すると強度が弱く障子のスライド性が悪くなる。
そこで、垂下片部を単にアルミと樹脂の組み合わせにすると、厚みがその分厚くなり、下枠上面に形成するスライド溝の間口幅が広くなり、下枠のバリアフリー性が悪くなる。
【0004】
このような事情から本発明は、障子の下框垂下片を嵌入する細い条状のスライド溝を形成した下枠上面略フラット構造の障子下框構造において、下枠上面に形成するスライド溝の間口幅を広げることなく、強度、断熱性が良く、意匠性に優れた障子構造の提供を目的とする。
【0005】
【課題を解決するための手段】
本発明は、上記目的を達成するために、建築物の屋外開口部に備えられた引き違い障子からなるサッシの下枠上面を略フラットに形成するとともに、この下枠上面に細い条状のスライド溝を備え、外障子下框の室内側より垂下片を垂下させて上記下枠のスライド溝に嵌入させた外障子下框構造において、金属製の下框ベース部の室内側よりから、一体的に垂下片ベース部材を垂下させるとともに、この下框ベース部から垂下片ベース部材にわたって樹脂形材からなる室内部材を取り付けたクラッドサッシ構造とし、室内部材の下端が下枠上面のスライド溝の上部に位置し、かつ、この室内部材の下端から樹脂薄片を垂下させてスライド溝部内に臨ませた。
【0006】
このように、金属製下框ベース部の室内側よりから、同じ金属製の垂下片ベース部材を一体的に垂下されることで、垂下片の強度を確保しつつ、下枠上面のスライド溝の上部直前までを樹脂製の室内部材でクラッド構造にし、室内部材の下端からこの室内部材と同色系の樹脂薄片をスライド溝部内まで垂下(延在)させたことにより、室内側からはアルミ等の金属製の垂下片が見えないようになる。
また、スライド溝部内には樹脂薄片を延在させたので、スライド溝幅をアルミ材単独に比較して広くする必要もなくなる。
【0007】
引き違い障子において、下框の室内側よりから垂下片を垂下させた外障子は、上記のような構造にし、これに対応した内障子下框に対しては、内障子下框の室外側よりから垂下片を垂下させ、下枠上面に設けた細い条状のスライド溝に嵌入させた構造にし、この内障子下框を金属製の下框ベース部と、その室内側に樹脂製の室内部材を取り付けたクラッド構造にすることにより、断熱性が優れただけでなく、外障子と内障子との意匠の統一性が図れる。
【0008】
【発明の実施の形態】
本発明に係るサッシ構造の縦断面図を図1に示し、その横断面図を図2に示す。
また、下枠部分の拡大図を図3に示す。
建築物の躯体開口部に下枠10、上枠20及び室内から室外側に向かって右縦枠30、左縦枠40にて略方形の枠体を形成し、その開口部に室外側から順に、網戸70、外障子50、内障子60がスライド開閉可能に取り付けられている。
なお、網戸は必要に応じて取り付けられるものである。
また、図に示した引き違い障子の場合には、外障子と内障子の2枚戸であるが、本発明は4枚戸等の引き違い障子等にも適用される。
【0009】
上枠20は、強度が確保しやすいアルミ押出材等の金属製からなる上枠ベース部材20aと20cを樹脂材等の断熱部材20dで連結し、断熱と意匠性を考慮して上枠室内部材20bをその室内側に配設した構造になっている。
【0010】
右縦枠30及び左縦枠40は、それぞれ金属製の縦枠ベース部材30a、40a、の室内側に樹脂製等の縦枠室内部材30b、40bを連結した断熱構造になっている。
【0011】
図3の拡大図に基づいて下枠構造を説明する。
下枠10の下枠ベース部は、室外側下枠ベース部材11と室内側下枠ベース部材12を断熱部材16にて連結して形成されている。
下枠ベース部材には、外障子50の戸車51c及び内障子60の戸車61cが走行する小さな条状突起からなる擬似レール19a、19bが形成されている。
この擬似レール部分とは、独立して分離出来るように下枠カバー部材15が下枠ベース部に着脱自在に取り付けられている。
下枠カバー部材15を下枠ベース部に取り付けることにより、外障子50の下框51の室内側よりから垂下させた垂下片51eがスライドする外障子用スライド溝13aが形成され、その下に排水用の外障子用下枠凹部14aが形成される。
また、この下枠カバー部材15にて外障子下框の垂下片51eの室内側に取り付けたタイト材51fの摺接壁を形成するとともに、内障子60の下框61の室外側よりから垂下させた垂下61eがスライドする内障子用スライド溝13bの室外側部を形成し、その下に排水用の内障子用下枠凹部14bが形成される。
なお、障子構造についての詳細は後で述べる。
このように下枠カバー部材15が障子の戸車走行部より独立しているので、下枠カバー部材15を引き違い障子の開閉に対して左右の開口部と中央部に分割して取り付けると、障子が一方に寄せて交互に下枠カバー部材を取り外すことができる。
この場合に中央部の下枠カバー部材は、障子召合部に対応した長さにするのがよい。
【0012】
下枠カバー部材にて形成された外障子下框垂下片51eと内障子下框垂下片61eの間の下枠上面は、図2に示す外障子召合框54と内障子召合框64が干渉しない範囲にて最接近させたことにより、その下枠上面幅が最小になっている。
また、この下枠カバー部材で形成した外障子下框垂下片と内障子下框垂下片の間の下枠上面にはホルダー部を設けて樹脂材等の断熱部材15aが配設されていて、この部分から熱伝導や結露の発生を防止している。
【0013】
また、下枠10の室内側よりの上面には、意匠性と断熱性を考慮して断熱室内部材17が取り付けられ、下枠上面には全体として略フラットに形成されている。
下枠10には下枠内部から室内(屋外)に雨水等を排水する排水穴18及び逆止弁18aが設けられている。
【0014】
外障子は、外障子下框51、外障子上框52、及び外障子戸当り框53と外障子召合框54にて略方形の枠を形成し、内側にガラス55等が装着されている。
なお、図1、図2に示す例では、二重のペアガラスタイプになっている。
また、上記下框、上框、戸当り框は、それぞれ金属製のベース部材51a、52a、53aの室内側に樹脂材等の断熱材からなる室内部材51b、52b、53bが連結されたクラッドサッシ構造となっている。
【0015】
外障子下框の上記クラッド構造の拡大図を図4(イ)に示し、外障子の下框51の室外側よりから外障子下框垂下片51eが垂下され、下枠上面に形成した外障子用スライド溝13aに嵌入するようになっている。
外障子下框垂下片51eの室内側には、スライド溝13aの上部直前まで樹脂製の室内部材51bが配設され、その下端に樹脂薄片51hが垂下し、スライド溝13a内に臨んでいる。
この樹脂薄片は、室内部材と同系色である。
また、垂下片51eの室内側で樹脂薄片の下にはタイト材51fが取り付けられ、下枠のスライド溝側壁(下枠凹部)との間をシールする。
また、外障子下框の底部と下枠上面との間にタイト材51gを取り付けてもよい。
図3に示すように、外障子下框底部には戸車51cが取り付けられ、戸車のタイヤの外周中央部は凹部形状51dになっていて、擬似レール19aと当接回転するようになっている。
【0016】
内障子60は、内障子下框61、上框62、戸当り框63、召合框64で略方形の枠を形成され、ガラス65等が取り付けられている。
なお、図1、図2に示す例では、二重のペアガラスタイプになっている。
また、上記下框、上框、戸当り框、召合框は、それぞれ金属製のベース部材61a、62a、63a、64aの室内側に樹脂材等の断熱材からなる室内部材61b、62b、63b、64bが連結されたフラットサッシ構造となっている。
【0017】
内障子の下框61の室外側よりから内障子下框垂下片61eが垂下され、下枠上面に形成した内障子用スライド溝13bに嵌入ようになっている。
本発明においては、外障子下框の垂下片が室内側よりから垂下され、内障子がその逆に内障子下框の室外側よりから垂下片を垂下させた構造になっている。
内障子下框垂下片61eの室内側にはタイト材61fが取り付けられ、下枠のスライド溝側壁(下枠凹部)との間をシールする。
内障子下框底部には戸車61cが取り付けられ、戸車のタイヤの外周中央部は凹部形状61dになっていて、擬似レール19bと当接回転するようになっている。
図4(ロ)に示すように、内障子の下框の室内部材61b下端には、この室内部材と同系色の臼片61hが取り付けられている。
【0018】
網戸70は、下框71、上框72、左右の縦框73、74にて略方形の枠を形成し、枠内に網75が張設されている。
網戸の下框には室内側よりから垂下片が垂下され、下枠のスライド溝に嵌入し、この垂下片と下枠のスライド溝にて虫押えラインを形成している。
【0019】
【発明の効果】
本発明においては、障子下框の室内側よりから垂下片を垂下させ、下枠上面の細い条状のスライド溝に嵌入させたバリアフリー構造とした場合に、スライド溝の上部直前までは金属と樹脂のクラッド構造とし、この樹脂材等の室内部材の下端からスライド溝部内に向けて樹脂薄片を垂下させたので、スライド溝幅を広くすることなく、室内側からは樹脂材等で形成した室内色しか見えないように統一出来る。
【0020】
また、下框から設けた垂下片の室内側を樹脂材等の断熱材にしたので、この部分からの外部熱伝導を防止出来るとともに、仮に、たとえ結露が生じた場合には室内部材の下端に延在させた樹脂薄片をつたって下枠のスライド溝から下枠凹部を経由して排水することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a shoji lower frame cladding sash structure having a structure in which a hanging piece is hung down from a shoji lower frame such as a sliding shoji, and the hanging piece is fitted into a slide groove formed on a lower frame upper surface substantially flat upper surface of the lower frame. .
[0002]
[Problems to be solved by the invention]
In examining a barrier-free sash structure in which the upper surface of the lower frame is formed substantially flat, the applicant of the present application makes a hanging piece drop down from the inside of the sliding door of the sliding door, and the inner sliding door frame From below, we examined a lower frame structure in which the hanging pieces were hung from the outside of the room, while a slide groove was formed on the upper surface of the lower frame to allow the hanging pieces to slide.
Even in such a barrier-free sash structure, there is a high demand for heat insulating sash specifications.
[0003]
When a metal sash such as an aluminum sash is used for the lower frame of the shoji, if the hanging piece of the outer sash is formed of aluminum or the like, the metal surface of the aluminum or the like is exposed to the indoor side, resulting in poor heat insulation and dew condensation. More likely to occur.
On the other hand, when the hanging pieces and the like are formed of resin, the strength is weak and the sliding property of the shoji becomes poor.
Therefore, if the hanging piece portion is simply made of a combination of aluminum and resin, the thickness increases accordingly, the width of the front face of the slide groove formed on the upper surface of the lower frame increases, and the barrier-free property of the lower frame deteriorates.
[0004]
In view of such circumstances, the present invention relates to a sliding frame lower frame structure having a substantially flat structure on a lower frame upper surface formed with a thin strip-shaped sliding groove into which a lower frame hanging piece of a shoji is inserted. It is an object of the present invention to provide a shoji structure having good strength and heat insulation properties and excellent design without expanding the width.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention forms a substantially flat upper surface of a lower frame of a sash made of a sliding shoji provided in an outdoor opening of a building, and a thin strip-shaped slide on the upper surface of the lower frame. In a sliding door lower frame structure in which a groove is provided and a hanging piece is hung from the indoor side of the sliding door lower frame and fitted into the sliding groove of the lower frame, from the indoor side of the lower frame base portion made of metal, The hanging member base member is suspended from the lower frame base portion and the hanging member base member has a clad sash structure in which an indoor member made of a resin profile is attached to the hanging member base member, and the lower end of the indoor member is located above the slide groove on the lower frame upper surface. And a resin flake was hung down from the lower end of the indoor member to face the slide groove.
[0006]
In this way, by hanging the same metal hanging piece base member integrally from the indoor side of the metal lower frame base portion, the strength of the hanging piece is ensured, and the sliding groove of the upper surface of the lower frame is secured. By forming a clad structure with a resin-made indoor member up to immediately before the upper portion, and by hanging (extending) a resin flake of the same color as the indoor member from the lower end of the indoor member to the inside of the slide groove portion, aluminum or the like is formed from the indoor side. The hanging pieces made of metal become invisible.
Further, since the resin flakes are extended in the slide groove, it is not necessary to make the width of the slide groove wider than that of the aluminum material alone.
[0007]
In the sliding door, the outer sliding door with the hanging piece hanging from the indoor side of the lower frame shall have the above structure, and the inner sliding door corresponding to this shall be from the outside of the inner lower sliding door. The hanging piece is suspended from the lower frame, and is fitted in a thin strip-shaped slide groove provided on the upper surface of the lower frame. In addition to having excellent heat insulation properties, the clad structure provided with allows the design of the outer sash and the inner sash to be uniform.
