Description

【0001】
【発明の属する技術分野】
本発明は、金属框と、その金属框の屋内側に露出される部分を覆う樹脂框とからなる横框を用いる断熱型障子に関する。
【0002】
【従来の技術】
上記のような断熱型障子は、金属枠と、その金属枠の行い側に露出される部分を覆う樹脂枠とからなる窓枠に建て付けて、複合サッシを構成する場合に用いられる。
この種の複合サッシには、実公昭63−49481号公報、特開平8−177316及び特開平8−177317号公報等に記載されたものが知られており、金属材の耐候性と強度及び樹脂材の断熱性と意匠性を併せ備えていて、外観及び内観をそれぞれ建物の外装及び内装と整合する統一的な意匠とすることができることから、寒冷地のみならず、非寒冷地においても採用されつつある。
【0003】
ところで、断熱型障子の縦框は、障子閉鎖時においては、縦枠の全長が凹溝に嵌合しているので、台風等の強大な正圧又は負圧に耐え得る強度を有しているが、上框や下框などの横框は、その上部又は下部などの一部のみが上レール又は下レールに気密材又は戸車及び気密材を介して比較的緩やかに嵌合して支持されているにすぎない。従って、強い風圧を受けやすいので、金属框と樹脂框との結合状態には相当の強度が要求される。
【0004】
【発明が解決しようとする課題】
しかしながら、樹脂框は耐衝撃性に弱いので、金属框と樹脂框をねじ等で結合する場合には、樹脂框側に予めねじ貫通孔を設けておく必要がある。従って、ねじ等で結合する従来の断熱型障子は、ねじ等の結合部材と、貫通孔の加工と、ねじ等の位置決め及びねじ込み作業とを必要とするため、製造コストが嵩さむ。
また、金属框はアルミニウム合金等で成形され、樹脂框は塩化ビニルやアクリル等などで成形されていて、熱膨脹収縮率が異なる。従って、ねじ等を貫通して結合する場合は、その伸縮率を考慮して、ねじ貫通孔を形成しないと、熱膨脹力によりねじ貫通部が破壊されるなどの不都合が生じやすい。
【0005】
このような難点を回避するため、金属框と樹脂框の一方に嵌合溝を、他方にその嵌合溝に嵌合し得る端縁を、框の高さ方向に隔てた2か所において全長に渡って形成し、両框を突き合わせ、一対の嵌合溝と端縁とを嵌合した後、他方の一対の嵌合溝と端縁と近付けて嵌合することにより結合して、ねじ等を用いない横框が採用されている。
【0006】
しかしながら、このような2対の嵌合による結合であるから、結合強度には限界があり、横框に強い風圧等の力が加わった時は、その嵌合状態が劣化して、歪みや変形を生じさせる恐れがあった。
【0007】
本発明は、上記の点に鑑みてなされたものであり、金属框と樹脂框を低コストで、容易に確実な結合強度をもって結合できる、断熱型障子の横框を提供することを課題としている。
【0008】
【課題を解決するための手段】
上記課題を解決するため、本発明は、金属框とその金属框の屋内側に露出される部分を覆う樹脂框とからなる上横框を用いる断熱型障子において、
前記金属框は、断面ほぼ矩形の筒部と、その筒部の一側面から上下方向に延長してそれぞれレール嵌合溝とガラス嵌合溝の一方の側壁を構成する上下の壁部とを有するとともに、前記筒部の一つの対角線上に存在する角部に、それぞれ屋内方向と下方向に開口し金属框の長手方向に延長する嵌合溝が形成され、かつ、前記筒部の屋内側であって前記嵌合溝を設けない角部に金属框の長手方向に延長する段部を形成してあり、
前記樹脂框は、前記レール嵌合溝及びガラス嵌合溝の他方の側壁を構成する上下の壁部を有するとともに、両壁部の間に前記金属框の前記筒部と重ね合わされ、かつ、先端が前記金属框の屋内方向に開口する嵌合溝に嵌合される結合縁と、前記下壁部の屋外側面に突設され、前記金属框の下方向に開口する嵌合溝にそれぞれ嵌合される結合縁とが形成され、かつ、前記上下の壁部の間に前記金属框の前記段部に対峙する段部を形成してあり、
前記金属框の段部に樹脂框の段部を対峙させるとともに、金属框の両嵌合溝に樹脂框の両結合縁をそれそれ嵌合させたことを特徴としている。
【0009】
上記構成により、金属框は強度を具備するための断面ほぼ矩形の筒部と、その筒部の一側面から上下方向に延長してそれぞれレール嵌合溝とガラス嵌合溝の一方の側壁を構成する上下の壁部とを有するから、断面形状が簡単で、成形が容易であり、しかも、従来の金属框とほぼ同程度の強度を備えている。また、樹脂框は、上下の壁部と中間及び一方の壁部に設けられた結合縁とを有する簡単な形状を有するので、これも成形が容易である。しかし、金属框と樹脂框は、筒部の一つの対角線上において樹脂框の結合縁を金属框の嵌合溝に嵌合し、かつ、金属框の段部に樹脂框の段部を対峙させているので、金属框と樹脂框の結合強度は格段に増強される。従って、横框は強い風圧等に対して大きな耐力を有する。
【0010】
【発明の実施の形態】
次に、本発明を障子の上框に適用した場合の実施例に基づいて、図面を参照しながら説明する。本発明は、下框に用いられる横框に対しても、ほぼ同様に適用することができる。
図1は、障子の上部の断面斜視図、図2は図1の金属框のみの分解正面図、図3は図1の障子を建て付けた複合サッシの縦断面図、図4は同じく横断面図である。
【0011】
図1において、hは上框であり、金属框10と、その金属框の屋内側に露出される部分を覆う樹脂框20とからなっている。金属框10は、アルミニウム合金等の形材で成形されて、耐候性と機械的強度に優れている。また、樹脂框20は、塩化ビニルやアクリル等で成形されて、断熱性と意匠性に優れている。
【0012】
側壁から上方に延び、窓枠の上レール(図示省略)を嵌合するためのレール嵌合溝30の屋外側壁を構成する上壁12と、下方に延び、障子のガラス50の上端部を嵌合するためのガラス嵌合溝40の屋外側壁を構成する下壁13とを一体に有し、上壁12の上端部には、前記上レールに押圧接触される気密材(図示省略)を取付けるためのあり溝14が形成されている。また、金属框10の筒部11の上面壁であるレール嵌合溝側のウェブ15には、この金属框10を障子の図示されていない縦框の金属框の戸先側外方から貫通されるビス及び召合せ框の金属框の戸尻側外方から貫通されるビスをねじ込むためのビスホール16が形成されている。
【0013】
そして、上壁12の屋内側面には、前記ウェブ15の付近において、屋内方向に突出する突縁17が形成されて、その突縁とウェブ15との間に、屋内方向に開口する嵌合溝18が形成されている。また、筒部11の下面壁であるガラス嵌合溝側のウェブ19の屋内側端部に下方に開口する嵌合溝110が設けられている。
また、図1において明らかなように、前記筒部11の屋内側であって前記嵌合溝110を設けない角部に金属框の長手方向に延長する段部120を形成してある。
【0014】
樹脂框20は、高さ方向中間部において屋外方向に延びる結合縁21と、その結合縁から上方に延び、レール嵌合溝30の屋内側壁を構成する上壁22と、結合縁21から下方に延び、ガラス嵌合溝40の屋内側壁を構成する下壁23とを一体に有している。また、上壁22の上端部には、前記上レールに押圧接触される気密材(図示省略)を取付けるためのあり溝24が形成されている。さらに、下壁23の屋外側面の高さ方向中間部には、金属框の嵌合溝110に嵌合するための結合縁25が設けられている。
また、図1において明らかなように、前記上下の壁部22、23の間に前記金属框の前記段部120に当接する段部220を形成してある。
【0015】
上記二つの框10,20を結合するには、次の二つの方法が可能である。その一つは、両框10,20を平行状態に対置し、まず、樹脂框20の上部結合縁21の先端を金属框10の上部嵌合溝18に押し込み、樹脂框をその弾性を利用して、下方に押し下げた瞬間に、樹脂框の下部結合縁25を金属框の下部嵌合溝110に嵌合する。樹脂框に対する押し下げ力を解放すると、弾性復元力により下部結合縁が僅かに上方に復帰するため、結合縁25は嵌合溝110内に緊密に嵌合固定される。
結合方法のもう一つは、両框10,20のほぼ一直線上において長手方向の互いに反対側の端部を対向させて、樹脂框の上下の結合縁21,25を金属框の上下の嵌合溝18,110に合致させ、両框を互いに反対方向に相対移動させて、各結合縁を各嵌合溝に嵌合し、固定させる。
また、前記したように、前記金属框の段部120には樹脂框の段部220が当接されている。
【0016】
上記のようにして、両框を嵌合により結合した後、金属框10の突縁17を、その長手方向の複数箇所において、必要によりカシメ機によりかしめて(図1の17a)、突縁17とウェブ15との間に上部結合縁21を強く挟持する。
【0017】
下部嵌合溝110を形成する屋外側の突縁も、その長手方向に間隔をもった位置でかしめるようにしても良い。本明細書において、「かしめる」なる用語は、金属框の突縁を物理力により変形させることを意味し、その手段方法を問わない。
【0018】
図3及び図4は、上記断熱障子が建て付けられた複合サッシの一例を示す。図3において、Hmは耐候性及び機械的強度に優れている金属、例えば、アルミニウム等で成形され、窓枠の上枠Hの屋外側に露出される部分を構成する金属枠であり、上枠を上下2か所で建物躯体に固定するための取付縁1,2を有し、また、外障子Doの上框hを案内する外レールroの屋外側部分を構成する垂下縁3を有している。
【0019】
Hpは、断熱性と意匠性に優れた、例えば、塩化ビニルやアクリル等の樹脂で成形され、金属枠Hmの屋内側に露出される部分を覆う樹脂枠であり、上枠Hの見込み幅増大の原因にならない位置には中空部4を有して二重壁構造とされ、また、内障子Diの制約された厚みの範囲内で可及的に大きな強度を得るため外レールroと同様の断面形状を有する中空状の内レールriを有するほかは、外レールroの屋内側部分を構成する垂下縁5及び屋内側端部の垂下縁6は、一重の厚みに形成されて、上枠Hの見込み幅を可及的に小さくされている。そして、上枠Hの外レールroは、金属枠Hmの垂下縁3と樹脂枠Hpの垂下縁5とで、内レールriと等しい断面形状を有している。
【0020】
Smは、下枠Sの屋外側に露出される部分を構成する金属枠であり、下枠を上下2か所で建物躯体に固定するための取付縁7,8を有し、内外の障子Di,Doの下框sを案内する内外のレールri,roを有している。下枠Sは、窓枠自体の荷重及び障子の全荷重を支持するので、窓枠の中で最も大きな強度が要求されるため、金属枠Smは従来の下枠の金属枠とほぼ同様の形状を備えており、屋内側端部に窓台や膳板に係止される逆L字形の雨返し壁9を有している。そして、雨返し壁9と内レールriとの間の溝10及び金属枠Smの雨返し壁9の上面を覆う樹脂枠Spが溝10に嵌合して装着されている。
【0021】
Jmは、窓枠の左右の縦枠J1 ,J2 の屋外側に露出される部分を構成する金属枠であり、所要の強度を備えるため、縦枠の屋外側端部から屋内側端部まで連続しており、その金属枠Jmの内障子Diに対応する内側面に樹脂枠Jpが内外2か所での嵌合及び金属枠Jmと樹脂枠Jpを重ね合せた部分におけるねじ11の締着により結合されている。縦枠の樹脂枠Jpは中空部を備えておらず、一重壁構造であるので、縦枠J1 、J2 の見込み幅が上枠H及び下枠Sに合せて縮小されている。
【0022】
次に、上記窓枠Fに建て付けられた引違い障子Di,Doの上框h及び下框sはいずれも、それぞれ金属框hm,smと、その金属框の屋内側露出部分を覆う樹脂框hp,spとからなり、金属框hm,smは従来と同様に薄肉に成形され、樹脂框hp,spは屋内側に中空部を備えていないので、従来の複合サッシにおける障子よりも可及的に薄肉に形成されている。戸先側(戸当たり側)の縦框j1 は、障子の開閉時に引寄せ部材bを介して窓枠の縦枠J1 ,J2 から強い衝突力を受ける場合があったり、閉鎖状態で強い風圧を受ける場合があるので、それらの衝突力や風圧に耐えるため、所要の強度を備えるため、戸先側の縦框j1の樹脂框jp1 には最小限の厚みを有する中空部tdが形成されている。
【0023】
【発明の効果】
上述のように、本発明によれば、金属框は、断面ほぼ矩形の筒部とその筒部の一側面から上下方向に延長してそれぞれレール嵌合溝とガラス嵌合溝の一方の側壁を構成する上下の壁部とを有する構造であるので、断面形状が簡単で成形が容易かつ安価にでき、しかも、従来の金属框とほぼ同程度の強度を備えており、また、樹脂框は、上下の壁部とその中間及び一方の壁部に設けられた結合縁とを有する簡単な構造であるので、これも成形が容易かつ安価にできる。そして、金属框と樹脂框は、筒部の一つの対角線上において樹脂框の結合縁を金属框の嵌合溝に嵌合されるとともに、金属框の段部には樹脂框の段部が対峙しているので、金属框と樹脂框の結合強度は格段に増強され、横框の耐風圧強度が非常に大きい。しかも、樹脂框と金属框の膨脹伸縮率の違いに基づく問題が巧みに解決される。

BACKGROUND OF THE INVENTION
The present invention relates to an adiabatic shoji using a reed comprising a metal reed and a resin reed covering a portion of the metal reed that is exposed on the indoor side.
[0002]
[Prior art]
The heat insulating shoji as described above is used when a composite sash is configured by being built on a window frame including a metal frame and a resin frame covering a portion exposed on the metal frame.
As this type of composite sash, those described in Japanese Utility Model Publication No. 63-49481, Japanese Patent Application Laid-Open No. 8-177316, Japanese Patent Application Laid-Open No. 8-177317, etc. are known. It is used not only in cold regions but also in non-cold regions, because it has both the heat insulation and design properties of the material, and the exterior and interior can be unified with the exterior and interior of the building. It's getting on.
[0003]
By the way, the vertical saddle of the heat-insulating shoji has a strength capable of withstanding strong positive pressure or negative pressure such as a typhoon because the full length of the vertical frame is fitted in the concave groove when the shoji is closed. However, the horizontal reeds such as the upper reed and lower reed are supported by relatively loosely fitting the upper or lower part of the reed to the upper or lower rail through the airtight material or the door roller and the airtight material. I'm just there. Therefore, since it is easy to receive a strong wind pressure, a considerable strength is required for the bonding state between the metal cage and the resin cage.
[0004]
[Problems to be solved by the invention]
However, since the resin cage is weak in impact resistance, it is necessary to provide a screw through hole in advance on the resin cage side when the metal cage and the resin cage are coupled with screws or the like. Therefore, the conventional heat-insulating shoji coupled with a screw or the like requires a coupling member such as a screw, processing of a through hole, and positioning and screwing operations of the screw or the like, resulting in an increase in manufacturing cost.
Further, the metal cage is molded from an aluminum alloy or the like, and the resin cage is molded from vinyl chloride, acrylic, or the like, and has different thermal expansion and contraction rates. Accordingly, in the case of coupling through a screw or the like, if the screw through hole is not formed in consideration of the expansion / contraction ratio, inconveniences such as destruction of the screw through portion due to thermal expansion force are likely to occur.
[0005]
In order to avoid such difficulties, the metal groove and the resin bottle have a fitting groove on one side and the other edge that can be fitted in the fitting groove on the other side is separated in the height direction of the bottle by the full length. After the two flanges are abutted and the pair of fitting grooves and the end edges are fitted together, the other pair of fitting grooves and the end edges are brought into close contact with each other to be joined, and screws, etc. A horizontal paddle that does not use is used.
[0006]
However, since it is a coupling by such two pairs of fittings, there is a limit to the coupling strength, and when a force such as a strong wind pressure is applied to the reeds, the fitting state deteriorates, and distortion or deformation There was a risk of causing.
[0007]
The present invention has been made in view of the above points, and an object of the present invention is to provide a reed of a heat-insulating type shoji that can be easily combined with a reliable bond strength between a metal cage and a resin cage at a low cost. .
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention is a heat-insulating type shoji using an upper reed consisting of a metal reed and a resin reed covering a portion exposed to the indoor side of the metal reed,
The metal rod has a cylindrical portion having a substantially rectangular cross section, and upper and lower wall portions extending in the vertical direction from one side surface of the cylindrical portion and constituting one side wall of the rail fitting groove and the glass fitting groove, respectively. In addition, a fitting groove that opens in the indoor direction and the downward direction and extends in the longitudinal direction of the metal rod is formed in each corner portion present on one diagonal line of the cylindrical portion, and on the indoor side of the cylindrical portion. A step portion extending in the longitudinal direction of the metal rod is formed at a corner portion where the fitting groove is not provided,
The resin rod has upper and lower wall portions constituting the other side wall of the rail fitting groove and the glass fitting groove, and is overlapped with the cylindrical portion of the metal rod between both wall portions , and the tip Is fitted to a fitting edge that is fitted in a fitting groove that opens in the indoor direction of the metal bowl and a fitting groove that protrudes on the outdoor side surface of the lower wall portion and opens in the downward direction of the metal bowl. And a stepped portion facing the stepped portion of the metal rod is formed between the upper and lower wall portions,
Together it is opposed to the step portion of the resin stile the stepped portion of the metal rail is characterized in that both coupling edges of the resin rail and it it-fitted into both fitting grooves of the metal rail.
[0009]
With the above configuration, the metal rod is configured to have a substantially rectangular cross section for strength, and one side wall of the rail fitting groove and the glass fitting groove extending from one side of the cylinder portion in the vertical direction. Therefore, the cross-sectional shape is simple, the molding is easy, and the strength is almost the same as that of a conventional metal rod. Further, the resin bowl has a simple shape having upper and lower wall portions and connecting edges provided in the middle and one wall portion, so that it is also easy to mold. However, metal stiles and resin stile has a joint edge of the resin rail fitted into the fitting groove of the metal stile on a diagonal line of one of the cylindrical portion and is opposed to the step portion of the resin stile the stepped portion of the metal stile Therefore, the bond strength between the metal cage and the resin cage is remarkably enhanced. Accordingly, the reed has a great proof strength against a strong wind pressure or the like.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described with reference to the drawings based on an example in which the present invention is applied to the upper arm of a shoji. The present invention can be applied in substantially the same manner to a recumbent used for a lower arm.
1 is a sectional perspective view of the upper part of the shoji, FIG. 2 is an exploded front view of only the metal fence of FIG. 1, FIG. 3 is a longitudinal sectional view of a composite sash in which the shoji of FIG. 1 is built, and FIG. FIG.
[0011]
In FIG. 1, h is an upper cage, and is composed of a metal cage 10 and a resin cage 20 that covers a portion of the metal cage that is exposed to the indoor side. The metal cage 10 is formed of a shape material such as an aluminum alloy and has excellent weather resistance and mechanical strength. Moreover, the resin cage | basket 20 is shape | molded by vinyl chloride, an acryl, etc., and is excellent in heat insulation and design property.
[0012]
The upper wall 12 that extends upward from the side wall and that constitutes the outdoor side wall of the rail fitting groove 30 for fitting the upper rail (not shown) of the window frame and the upper end of the shoji glass 50 extends downward. An airtight material (not shown) that presses and contacts the upper rail is attached to the upper end of the upper wall 12 integrally with the lower wall 13 that constitutes the outdoor side wall of the glass fitting groove 40 for joining. A dovetail groove 14 is formed. Moreover, the rail 15 is inserted into the web 15 on the rail fitting groove side, which is the upper surface wall of the cylindrical portion 11 of the metal rod 10, from the outside of the door side of the vertical rod metal rod not shown. A screw hole 16 is formed for screwing a screw penetrating from the outside of the door butt side of the screw and the metal bowl of the summon bowl.
[0013]
Further, a protruding edge 17 protruding in the indoor direction is formed in the vicinity of the web 15 on the indoor side surface of the upper wall 12, and a fitting groove opening in the indoor direction is formed between the protruding edge and the web 15. 18 is formed. Further, a fitting groove 110 that opens downward is provided at the indoor side end of the web 19 on the glass fitting groove side, which is the bottom wall of the cylindrical portion 11.
Further, as is apparent from FIG. 1, a step portion 120 extending in the longitudinal direction of the metal rod is formed at the corner portion on the indoor side of the cylindrical portion 11 where the fitting groove 110 is not provided.
[0014]
The resin rod 20 has a coupling edge 21 extending in the outdoor direction at an intermediate portion in the height direction, an upper wall 22 extending upward from the coupling edge and constituting an indoor side wall of the rail fitting groove 30, and downward from the coupling edge 21. The lower wall 23 which extends and constitutes the indoor side wall of the glass fitting groove 40 is integrally provided. Further, a dovetail groove 24 for attaching an airtight material (not shown) pressed against the upper rail is formed at the upper end portion of the upper wall 22. Further, a coupling edge 25 for fitting into the fitting groove 110 of the metal rod is provided at the height direction intermediate portion of the outdoor side surface of the lower wall 23.
Further, as is apparent from FIG. 1, a stepped portion 220 is formed between the upper and lower wall portions 22 and 23 to contact the stepped portion 120 of the metal rod.
[0015]
The following two methods can be used to connect the two cages 10 and 20. One of them is that the two flanges 10 and 20 are opposed to each other in parallel, and first, the tip of the upper coupling edge 21 of the resin rod 20 is pushed into the upper fitting groove 18 of the metal rod 10 and the resin rod is utilized by its elasticity. Then, at the moment when it is pushed down, the lower coupling edge 25 of the resin cage is fitted into the lower fitting groove 110 of the metal cage. When the pushing-down force on the resin rod is released, the lower coupling edge returns slightly upward due to the elastic restoring force, so that the coupling edge 25 is closely fitted and fixed in the fitting groove 110.
Another bonding method is to fit the upper and lower coupling edges 21 and 25 of the metal rods to the upper and lower sides of the metal rods with the ends opposite to each other in the longitudinal direction facing each other on a substantially straight line of both the rods 10 and 20. The grooves 18 and 110 are matched with each other, and both ribs are moved relative to each other in the opposite directions, so that each coupling edge is fitted into each fitting groove and fixed.
Further, as described above, the step 220 of the resin cage is in contact with the step 120 of the metal cage.
[0016]
As described above, after joining the two flanges by fitting, the protruding edges 17 of the metal flange 10 are caulked by a caulking machine at a plurality of locations in the longitudinal direction as necessary (17a in FIG. 1), and the protruding edges 17 The upper coupling edge 21 is strongly sandwiched between the web 15 and the web 15.
[0017]
The protruding edge on the outdoor side forming the lower fitting groove 110 may also be caulked at a position spaced in the longitudinal direction. In the present specification, the term “caulking” means that the protruding edge of the metal rod is deformed by physical force, and the means is not limited.
[0018]
FIG.3 and FIG.4 shows an example of the composite sash in which the said heat insulating shoji was built. In FIG. 3, Hm is a metal frame which is formed of a metal having excellent weather resistance and mechanical strength, such as aluminum, and constitutes a portion exposed to the outdoor side of the upper frame H of the window frame. Has mounting edges 1 and 2 for fixing the upper and lower sides to the building frame, and also has a hanging edge 3 that constitutes the outdoor side portion of the outer rail ro that guides the upper arm h of the shoji Do. ing.
[0019]
Hp is a resin frame that is excellent in heat insulation and design, for example, is formed of a resin such as vinyl chloride or acrylic, and covers a portion exposed to the indoor side of the metal frame Hm, and the expected width of the upper frame H is increased. The hollow portion 4 is provided at a position that does not cause the double-wall structure, and the same as the outer rail ro in order to obtain as much strength as possible within the range of the restricted thickness of the inner limb Di. Besides having a hollow inner rail ri having a cross-sectional shape, the hanging edge 5 constituting the indoor side portion of the outer rail ro and the hanging edge 6 at the indoor side end are formed in a single thickness, and the upper frame H The prospect range has been made as small as possible. The outer rail ro of the upper frame H has the same cross-sectional shape as the inner rail ri at the hanging edge 3 of the metal frame Hm and the hanging edge 5 of the resin frame Hp.
[0020]
Sm is a metal frame that constitutes a portion of the lower frame S that is exposed to the outdoor side, and has mounting edges 7 and 8 for fixing the lower frame to the building frame in two places, upper and lower, and an inner and outer shoji Di. , Do has inner and outer rails ri, ro for guiding the lower arm s. Since the lower frame S supports the load of the window frame itself and the total load of the shoji, the highest strength is required among the window frames. Therefore, the metal frame Sm has almost the same shape as the metal frame of the conventional lower frame. And has an inverted L-shaped rain return wall 9 which is locked to a window sill or a wall plate at an indoor side end. A groove 10 between the rain return wall 9 and the inner rail ri and a resin frame Sp that covers the upper surface of the rain return wall 9 of the metal frame Sm are fitted into the groove 10 and attached.

Jm is a metal frame that forms the exposed part of the left and right vertical frames J1 and J2 of the window frame on the outdoor side. Since it has the required strength, it is continuous from the outdoor side edge to the indoor side edge of the vertical frame. The resin frame Jp is fitted to the inner surface of the metal frame Jm corresponding to the inner impingement Di at two locations inside and outside, and the screw 11 is fastened at the portion where the metal frame Jm and the resin frame Jp are overlapped. Are combined. Since the vertical frame resin frame Jp does not have a hollow portion and has a single wall structure, the expected widths of the vertical frames J1 and J2 are reduced in accordance with the upper frame H and the lower frame S.
[0022]
Next, the upper cover h and the lower cover s of the sliding shoji Di, Do built in the window frame F are respectively the metal cover hm, sm and the resin cover that covers the exposed part of the metal cover on the indoor side. Since the metal cages hm and sm are formed into a thin wall as in the prior art, and the resin cages hp and sp do not have a hollow portion on the indoor side, they are as much as possible than the shoji screen in the conventional composite sash. It is formed in a thin wall. The vertical edge j1 on the door end side (door-to-door side) may receive a strong collision force from the vertical frames J1 and J2 of the window frame via the pulling member b when opening and closing the shoji, or it may cause a strong wind pressure in the closed state. In order to withstand the impact force and wind pressure, the resin rod jp1 of the vertical rod j1 on the door side has a hollow portion td having a minimum thickness. .

【The invention's effect】
As described above, according to the present invention, the metal rod extends in the vertical direction from one side surface of the cylindrical portion having a substantially rectangular cross section and the cylindrical portion, and has one side wall of the rail fitting groove and the glass fitting groove, respectively. Since it has a structure having upper and lower wall parts to be configured, the cross-sectional shape is simple, it can be molded easily and inexpensively, and it has almost the same strength as a conventional metal cage, and the resin cage is Since it has a simple structure having upper and lower wall portions and intermediate and middle edges of the wall portions, it can be easily and inexpensively molded. Then, the metal stiles and resin stile has a joint edge of the resin rail with fitted into the fitting groove of the metal stile on one diagonal line of the cylindrical portion, facing the stepped portion of the resin stile is a stepped portion of the metal stile As a result, the bond strength between the metal cage and the resin cage is remarkably enhanced, and the wind pressure resistance strength of the horizontal cage is very high. Moreover, the problem based on the difference in expansion / contraction ratio between the resin cage and the metal cage is skillfully solved.
