For example, when the resin frame body 30 is formed by extrusion molding, the outdoor side reinforcing portion 41 and the indoor side reinforcing portion 42 made of metal are arranged inside the mold, and the outdoor side reinforcing portion 41 and the indoor side reinforcing portion 42 are arranged. , and the resin frame 30 is molded so as to wrap the outdoor-side reinforcing portion 41 and the indoor-side reinforcing portion 42 . Moreover, it is preferable that the outdoor-side reinforcing portion 41 and the indoor-side reinforcing portion 42 are in close contact with the outdoor-side frame portion 3a and the indoor-side frame portion 3b with a shear strength of 2 MPa or more, respectively.

上框２２は下框２３を上下反転させたものと同様であり、縦框２１は下框２３を見付け面に沿って９０度回転させたものと同様であり、それぞれ説明を省略する。縦框２１においては、屋外側補強部４１及び屋内側補強部４２が戸先框２１Ａ及び召合せ框２１Ｂの両方に設けられていてもよいし、屋外側補強部４１及び屋内側補強部４２が召合せ框２１Ｂにのみに設けられていてもよい。 The upper frame 22 is the same as the lower frame 23 turned upside down, and the vertical frame 21 is the same as the lower frame 23 rotated 90 degrees along the face, and the description of each is omitted. In the vertical frame 21, the outdoor reinforcing portion 41 and the indoor reinforcing portion 42 may be provided on both the door frame 21A and the meeting frame 21B, or the outdoor reinforcing portion 41 and the indoor reinforcing portion 42 may be It may be provided only on the meeting frame 21B.

連結板部３８、端部板部３７、屋外側第二板部３２の下部及び屋内側第二板部３４の下部により、中空部ｓ１が形成されている。 The connecting plate portion 38, the end plate portion 37, the lower portion of the outdoor side second plate portion 32, and the lower portion of the indoor side second plate portion 34 form a hollow portion s1.

連結板部３８の上側（見付け方向の内側）には、ガラス２９を支持するゴム等の弾性材からなる支持部材４６が設けられている。 A support member 46 made of an elastic material such as rubber for supporting the glass 29 is provided on the upper side (inner side in the view direction) of the connecting plate portion 38 .

屋外側第二板部３２の上端部３２ｕ及び屋内側第二板部３４の上端部３４ｕには、ガラス２９を押圧するゴム等の弾性材からなるヒレ部４７が設けられている。 The upper end portion 32 u of the outdoor side second plate portion 32 and the upper end portion 34 u of the indoor side second plate portion 34 are provided with a fin portion 47 made of an elastic material such as rubber for pressing the glass 29 .

このように構成された引違いサッシ１００では、屋外側補強部４１及び屋内側補強部４２が樹脂框体３０に内包され樹脂框体３０に接合されて一体に構成されることで、框体２０の強度が確保されている。よって、従来のように、断面コ字状や矩形状等の断面が立体的な芯材を設けて框体の剛性を高める必要がなく、断面形状を抑えた屋外側補強部４１及び屋内側補強部４２を用いることができる。したがって、框体２０の強度を確保しつつ、框体２０をスリムなデザインとすることができる。 In the double sliding sash 100 configured as described above, the outdoor reinforcing portion 41 and the indoor reinforcing portion 42 are included in the resin frame 30 and joined to the resin frame 30 to be integrated. strength is ensured. Therefore, unlike the conventional art, there is no need to provide a core material with a three-dimensional cross section such as a U-shape or a rectangular cross section to increase the rigidity of the frame body, and the outdoor side reinforcement part 41 and the indoor side reinforcement part with a suppressed cross-sectional shape are provided. A portion 42 can be used. Therefore, the strength of the frame body 20 can be ensured, and the frame body 20 can have a slim design.

また、屋外側補強部４１及び屋内側補強部４２の板面４１ａ，４２ｂが見付け面に沿って配置されているため、屋外側補強部４１及び屋内側補強部４２における風圧（屋内外方向の圧力）を受ける部分の面積（見付け面）を大きく確保することができる。よって、耐風圧に対する強度を高めることができる。また、従来のように、ガラス２９の外側（延在方向の外側であって、例えば下框２３ならばガラス２９の下方）に必ずしも芯材を設ける必要がないため、框体２０の幅（見付け面に沿う長さ）ｅ（図３参照）を小さくしてスリムなデザインとすることができる。 Further, since the plate surfaces 41a and 42b of the outdoor-side reinforcing portion 41 and the indoor-side reinforcing portion 42 are arranged along the facing surface, wind pressure (indoor-outdoor direction pressure) in the outdoor-side reinforcing portion 41 and the indoor-side reinforcing portion 42 ) can be ensured to have a large area (viewing surface). Therefore, the strength against wind pressure can be increased. In addition, unlike the conventional art, it is not necessary to provide a core material outside the glass 29 (outside in the extending direction, for example, below the glass 29 in the case of the lower frame 23). A slim design can be achieved by reducing the length along the surface e (see FIG. 3).

また、屋外側補強部４１及び屋内側補強部４２の上端部４１ｕ，４２ｕはガラス２９と重なって配置されているため、ガラス２９が受ける風圧を屋外側補強部４１及び屋内側補強部４２でも確実に抗することができる。よって、耐風圧に対する強度を一層高めることができる。 In addition, since the upper ends 41u and 42u of the outdoor side reinforcing portion 41 and the indoor side reinforcing portion 42 are arranged so as to overlap with the glass 29, the outdoor side reinforcing portion 41 and the indoor side reinforcing portion 42 also reliably absorb the wind pressure that the glass 29 receives. can resist. Therefore, the strength against wind pressure can be further increased.

また、屋外側補強部４１及び屋内側補強部４２は金属製であるため、框体２０の強度を確実に確保することができる。 In addition, since the outdoor-side reinforcing portion 41 and the indoor-side reinforcing portion 42 are made of metal, the strength of the frame 20 can be reliably secured.

また、風圧が大きく作用する召合せ框２１Ｂ（召合せ部分）に屋外側補強部４１及び屋内側補強部４２が設けられているため、召合せ框２１Ｂが変形したりすることが抑制される。 In addition, since the outdoor side reinforcing portion 41 and the indoor side reinforcing portion 42 are provided in the meeting frame 21B (joint portion) where the wind pressure is large, deformation of the meeting frame 21B is suppressed.

また、連結板部３８、端部板部３７、屋外側第二板部３２の下部及び屋内側第二板部３４の下部により、中空部ｓ１が形成されている。框体２０の変形を中空部ｓ１で吸収することができるとともに、中空部ｓ１により断熱性を高めることができる。 A hollow portion s1 is formed by the connecting plate portion 38, the end plate portion 37, the lower portion of the outdoor side second plate portion 32, and the lower portion of the indoor side second plate portion 34. As shown in FIG. The deformation of the frame 20 can be absorbed by the hollow portion s1, and the heat insulating property can be enhanced by the hollow portion s1.

For example, the upper end portions 41 u and 42 u of the outdoor reinforcing portion 41 and the indoor reinforcing portion 42 of the lower rail 23 may be arranged below the lower end portion 29 d of the glass 29 .

また、上記に示す実施形態では、芯材として、ガラス２９を挟んで屋内外方向の両側に屋外側補強部４１及び屋内側補強部４２が配置されているが、本発明はこれに限られない。芯材が、パネル材の屋内側及び屋外側のいずれか一方にのみ配置されていてもよい。召合せ框２１Ｂにおいて、各障子２の屋内外方向の一方側にのみ芯材が設けられるのであれば、芯材が外障子（屋外側の障子）２Ａでは屋外側の部分２１ｃ及び内障子（屋内側の障子）２Ｂでは屋内側２１ｄに設けられることが、耐風圧上好ましい（図２参照）。 In addition, in the embodiment shown above, the outdoor-side reinforcing portion 41 and the indoor-side reinforcing portion 42 are arranged on both sides in the indoor/outdoor direction with the glass 29 interposed as the core material, but the present invention is not limited to this. . The core material may be arranged only on either one of the indoor side and the outdoor side of the panel material. In the meeting frame 21B, if the core material is provided only on one side of each shoji 2 in the indoor/outdoor direction, the core material is the outdoor side portion 21c and the inner shoji (outdoor side shoji) 2A. In terms of wind pressure resistance, it is preferable that the inner shoji 2B is provided on the indoor side 21d (see FIG. 2).

また、上記に示す実施形態では、屋外側框部３ａ及び屋内側框部３ｂは、それぞれ屋外側補強部４１及び屋内側補強部４２の全ての面を覆うように内包しているが、本発明はこれに限られない。樹脂部材が芯材を内包する構成は、芯材の一面が露出しつつ芯材の他の面を覆う形態や、芯材の一部が露出しつつ芯材の残りの部分を覆う形態等であってもよい。 In addition, in the above-described embodiment, the outdoor-side frame portion 3a and the indoor-side frame portion 3b are included so as to cover all surfaces of the outdoor-side reinforcing portion 41 and the indoor-side reinforcing portion 42, respectively. is not limited to this. The configuration in which the resin member encloses the core material includes a configuration in which one surface of the core material is exposed while covering the other surface of the core material, and a configuration in which a portion of the core material is exposed while covering the rest of the core material. There may be.

また、屋外側框部３ａ及び屋内側框部３ｂを構成する樹脂としては、熱可塑性樹脂が好ましく、塩化ビニル系樹脂、塩素化ポリエチレン、ポリスチレン、ポリプロピレン、ＡＢＳ、ＡＥＳ等が挙げられ、成形がし易く曲げ剛性や耐久性を有した建具に好適な塩化ビニル系樹脂が特に好ましい。 Thermoplastic resins, such as vinyl chloride resins, chlorinated polyethylene, polystyrene, polypropylene, ABS, and AES, are preferred as resins forming the outdoor side frame portion 3a and the indoor side frame portion 3b. Vinyl chloride-based resins are particularly preferable because they are easy to use and are suitable for fittings having bending rigidity and durability.
