上面被覆部材26の上面被覆部26aには、内レール部材30の基部31を係合させる内レール係合部26cが形成されており、内レール部材30の基部31は内レール係合部26cに係合すると共に、ネジ止めにより上面被覆部材26に対して固定される。この固定に用いられるネジ28は、金属下枠20の上面を貫通して中空内部にまで達しており、これによって内レール部材30を金属下枠20に対しても固定している。   An inner rail engaging portion 26c for engaging the base portion 31 of the inner rail member 30 is formed on the upper surface covering portion 26a of the upper surface covering member 26, and the base portion 31 of the inner rail member 30 is connected to the inner rail engaging portion 26c. While being engaged, it is fixed to the upper surface covering member 26 by screwing. The screw 28 used for fixing passes through the upper surface of the metal lower frame 20 and reaches the hollow interior, thereby fixing the inner rail member 30 to the metal lower frame 20 as well.

このように、内レール32を金属下枠20とは別体の金属材で形成した内レール部材30に設け、この内レール部材30を樹脂材からなる上面被覆部材26に載置固定しているので、内レール32は金属下枠20と熱絶縁されている。したがって、内障子2の荷重を支える内レール32の強度を充分に確保しつつ、これが室内側に露出することによる断熱性の悪化を防ぐことができる。   Thus, the inner rail 32 is provided on the inner rail member 30 formed of a metal material separate from the metal lower frame 20, and the inner rail member 30 is placed and fixed on the upper surface covering member 26 made of a resin material. Therefore, the inner rail 32 is thermally insulated from the metal lower frame 20. Therefore, while ensuring the strength of the inner rail 32 that supports the load of the inner impeller 2, it is possible to prevent the heat insulation from being deteriorated due to the exposure to the indoor side.

また、内レール32と外レール21の間の領域には、長手方向略全長に渡って中間上面材34が設けられる。中間上面材34は、金属材によって形成されており、上面34aは内障子2の室外面近傍から外障子3の戸車7近傍に渡ると共に、内レール32や外レール21及び室内立ち上がり片23の上端位置と略同じ高さとなるように形成されている。   An intermediate upper surface member 34 is provided in the region between the inner rail 32 and the outer rail 21 over substantially the entire length in the longitudinal direction. The intermediate upper surface member 34 is formed of a metal material, and the upper surface 34 a extends from the vicinity of the outdoor surface of the inner shuffler 2 to the vicinity of the door 7 of the outer obstacle 3, and the upper end of the inner rail 32, the outer rail 21, and the indoor rising piece 23. It is formed to be approximately the same height as the position.

中間上面材34を下枠11に固定するため、上面被覆部材26の室外端部上面には上面材取付部品35が設けられる。上面材取付部品35は、樹脂材からなる小片状の部品として形成されており、下枠11の長手方向に沿って所定間隔おきに複数が設けられる。上面材取付部品35は、下枠11に対して取付けられる基部35aを有すると共に、その上面には中間上面材34を固定するための係合片35bが設けられる。   In order to fix the intermediate upper surface material 34 to the lower frame 11, an upper surface material attachment component 35 is provided on the upper surface of the outdoor end portion of the upper surface covering member 26. The upper surface material mounting part 35 is formed as a small piece part made of a resin material, and a plurality of the upper surface material mounting parts 35 are provided at predetermined intervals along the longitudinal direction of the lower frame 11. The upper surface material attachment component 35 has a base portion 35a attached to the lower frame 11, and an engagement piece 35b for fixing the intermediate upper surface material 34 is provided on the upper surface thereof.

上面材取付部品35の下面には、上面被覆部材26及び内レール部材30の室外端部によって形成される凹部29に係合する下面係合部35dが室内側を向くように形成されている。また、上面材取付部品35の室外面には、逆J字状の弾性係合部35cが形成されている。弾性係合部35cは、薄板状に形成されているので、室内外方向に弾性を有しており、その先端が外レール21の上端近傍に形成された鍔部21aに係合することにより、上面材取付部品35を室内側に付勢された状態とする。これにより、下面係合部35dは凹部29側に押しつけられて、上面材取付部品35が下枠11に固定された状態となる。   A lower surface engaging portion 35d that engages with a concave portion 29 formed by the outdoor end portions of the upper surface covering member 26 and the inner rail member 30 is formed on the lower surface of the upper surface material attachment component 35 so as to face the indoor side. Further, an inverted J-shaped elastic engagement portion 35 c is formed on the outdoor surface of the upper surface member mounting component 35. Since the elastic engagement portion 35 c is formed in a thin plate shape, the elastic engagement portion 35 c has elasticity in the indoor / outdoor direction, and its tip engages with the flange portion 21 a formed near the upper end of the outer rail 21. The upper surface member attachment component 35 is biased to the indoor side. Thereby, the lower surface engaging portion 35d is pressed against the concave portion 29 side, and the upper surface material attachment component 35 is fixed to the lower frame 11.

中間上面材34は下面に取付部34bを有しており、この取付部34bが上面材取付部品35の係合片35bと係合することにより、中間上面材34が上面材取付部品35に対して固定される。中間上面材34は、各上面材取付部品35と係合されることにより、長手方向に沿って複数個所で下枠11に対して固定される。   The intermediate upper surface member 34 has a mounting portion 34 b on the lower surface, and the intermediate upper surface member 34 is attached to the upper surface member mounting component 35 by engaging the mounting portion 34 b with the engaging piece 35 b of the upper surface member mounting component 35. Fixed. The intermediate upper surface member 34 is fixed to the lower frame 11 at a plurality of locations along the longitudinal direction by being engaged with each upper surface member attachment component 35.

金属下枠20の室内側面を被覆するように設けられる室内面被覆部材27は、金属下枠20の室内側面を覆う室内面被覆部27aと、その上端から室内側に向かって延出されるアングル構成部27bとが一体的に形成されて断面略L字状をなすように形成されている。アングル構成部27bは、枠体1の室内側に設けられる床材(図示しない)の上面に当接してネジ止めされ、さらにその上面にはアングルカバー材14が設けられて、下枠11から室内側に延出されたアングル片15を構成する。   The indoor surface covering member 27 provided so as to cover the indoor side surface of the metal lower frame 20 includes an indoor surface covering portion 27a that covers the indoor side surface of the metal lower frame 20, and an angle configuration that extends from the upper end toward the indoor side. The portion 27b is integrally formed to have a substantially L-shaped cross section. The angle component 27b is in contact with the upper surface of a floor material (not shown) provided on the indoor side of the frame body 1 and screwed, and further, the angle cover material 14 is provided on the upper surface of the angle component 27b. An angle piece 15 extending inward is formed.

内レール32と室内立ち上がり片23の間の領域には、室内上面材33が設けられる。室内上面材33は金属材からなり略薄板状をなすように形成される。室内上面材33の室外端部は、内レール32の上端近傍に形成される鍔部32aに係合し、一方で室内上面材33の室内端部は、上面被覆部材26を構成する立ち上がり被覆部26bの上端部分と係合する。   An indoor upper surface material 33 is provided in a region between the inner rail 32 and the indoor rising piece 23. The indoor upper surface member 33 is made of a metal material and is formed in a substantially thin plate shape. The outdoor end portion of the indoor upper surface member 33 engages with a flange portion 32 a formed in the vicinity of the upper end of the inner rail 32, while the indoor end portion of the indoor upper surface member 33 is a rising covering portion that constitutes the upper surface covering member 26. Engage with the upper end of 26b.

そして、室内上面材33は、立ち上がり被覆部26bが被覆する立ち上がり片23に対しては、接触しないようにされている。これにより、室内上面材33は金属下枠20に対しては熱絶縁された状態となっている。また、室内上面材33は、立ち上がり被覆部26bの上端部分と内レール32の上端近傍の鍔部32aにそれぞれ係合し取付けられているため、その上面33aは内レール32や室内立ち上がり片23の上端位置と略同じ高さとなっている。   And the indoor upper surface material 33 is made not to contact the rising piece 23 which the rising coating | coated part 26b coat | covers. As a result, the indoor upper surface member 33 is thermally insulated from the metal lower frame 20. Further, since the indoor upper surface member 33 is engaged with and attached to the upper end portion of the rising covering portion 26b and the flange portion 32a in the vicinity of the upper end of the inner rail 32, the upper surface 33a is formed on the inner rail 32 and the indoor rising piece 23. The height is substantially the same as the upper end position.

このように、内レール32と室内立ち上がり片23の間に金属材からなる室内上面材33を設け、室内上面材33を金属下枠20から熱絶縁されるように固定することで、下枠11上面の強度を大きくしつつ、断熱性も確保することができる。また、室内上面材33が取付けられる内レール部材30も、前述のように金属下枠20からは熱絶縁されているので、より断熱性の高い下枠フラットサッシとすることができる。   Thus, the indoor upper surface material 33 made of a metal material is provided between the inner rail 32 and the indoor rising piece 23, and the indoor upper surface material 33 is fixed so as to be thermally insulated from the metal lower frame 20. Heat insulation can be secured while increasing the strength of the upper surface. Moreover, since the inner rail member 30 to which the indoor upper surface member 33 is attached is also thermally insulated from the metal lower frame 20 as described above, a lower frame flat sash with higher heat insulation can be obtained.

なお、室内上面材33は、本実施形態では室内端部が樹脂下枠25を構成する上面被覆部材26の立ち上がり被覆部26bの上端と係合し固定されているが、金属下枠20と熱絶縁されていれば、樹脂下枠25を構成する室内面被覆部材27に対して係合固定するようにしてもよい。この場合には、室内上面材33が立ち上がり片23の上方を接触しないように跨ぐ必要があるので、立ち上がり片23の高さを若干低くする必要がある。   In the present embodiment, the indoor upper surface member 33 has an indoor end portion engaged with and fixed to the upper end of the rising covering portion 26b of the upper surface covering member 26 constituting the resin lower frame 25. As long as it is insulated, it may be engaged and fixed to the indoor surface covering member 27 constituting the resin lower frame 25. In this case, since it is necessary to straddle the indoor upper surface material 33 so as not to contact the upper part of the rising piece 23, the height of the rising piece 23 needs to be slightly lowered.

金属下枠20の外レール21と網戸レール22の間には、室外上面材36が取付けられる。室外上面材36は、金属下枠20の上面及び網戸レール22の室内面にそれぞれ係合して固定されており、上面36aは内レール32や外レール21の上端位置と略同じ高さを有すると共に、網戸4の室内面近傍から外障子3の室外面近傍に渡るように形成されている。   An outdoor upper surface member 36 is attached between the outer rail 21 and the screen door rail 22 of the metal lower frame 20.

次に、内障子2の内障子戸当たり部材40に対する当接部分について説明する。図10には、内障子2の召合せ部分における下端部近傍の拡大斜視図を示している。この図に示すように、内障子2の召合せ部分においては、縦方向の框材である召合せ框61と横方向に框材である下框60とが連結されている。下框60は、端面が召合せ框61の内側面に突き合わされており、両者はビス止めされることにより連結されている。   Next, the abutting portion of the inner limb 2 against the inner limb door contact member 40 will be described. FIG. 10 shows an enlarged perspective view of the vicinity of the lower end portion in the summon portion of the shoji 2. As shown in this figure, in the summing part of the inner shoji 2, a summing rod 61 that is a vertical collar and a lower collar 60 that is a lateral collar are connected in the horizontal direction. The end surface of the lower collar 60 is abutted against the inner surface of the summon 61, and both are connected by being screwed.

下框60には、前述の内障子垂下片2bが長手方向に沿って形成されている。召合せ框61の下端部には、樹脂材からなる内障子下端ブロック50が取付けられており、この内障子下端ブロック50に形成された内障子垂下片延長部52により、内障子垂下片2bが内障子2の端部まで延長される。そして、内障子垂下片延長部52の端面が内障子戸当たり部材40に当接自在となる。   On the lower eyelid 60, the above-described inner pendulum hanging piece 2b is formed along the longitudinal direction. A lower end block 50 made of a resin material is attached to the lower end portion of the summon bowl 61, and the inner peg hanging piece 2 b is formed by the inner peg hanging piece extension 52 formed on the lower end block 50. It is extended to the end of the inner shoji 2. Then, the end surface of the pendulum hanging piece extension portion 52 can freely come into contact with the member for hitting the door part 40.

内障子垂下片2bの先端部には、気密材2aを取付けることのできる気密材保持部2cが形成されている。なお、図10では気密材2aは省略している。内障子下端ブロック50の内障子垂下片延長部52には、先端部に気密材2aと連続状となる気密材を保持する気密材延長部53が形成されている。気密材延長部53により、内障子2の下辺において端部にまで連続状に気密材を設けることができ、内障子2と枠体1との間の気密性を高くすることができる。   An airtight material holding portion 2c to which the airtight material 2a can be attached is formed at the distal end portion of the pendulum hanging piece 2b. In addition, the airtight material 2a is abbreviate | omitted in FIG. An airtight material extension 53 for holding an airtight material continuous with the airtight material 2a is formed at the distal end of the internal pendulum hanging piece extension 52 of the lower end block 50 of the internal impeller. By the airtight material extension 53, the airtight material can be provided continuously to the end portion of the lower side of the inner impingement 2, and the airtightness between the inner impediment 2 and the frame 1 can be increased.

図11には、内障子下端ブロック50の斜視図を示している。この図に示すように、内障子下端ブロック50は、召合せ框61の中空内部に挿入されて固定される挿入部51を備え、その下部に前述の内障子垂下片延長部52が一体的に形成されている。   FIG. 11 shows a perspective view of the lower end block 50 of the inner shoji.
