In the sash of the present embodiment, as shown in FIG. 4, among the inner peripheral recesses 11f of the upper frame 11 that guides the inner sash 2, the indoor side portion of the outer sash 3 when the inner and outer sashes 2 and 3 are closed. Is provided with an upper resin cover 51.

上樹脂カバー５１は、上枠１１の内周凹部１１ｆに取り付けられる樹脂カバー本体５１１と、樹脂カバー本体５１１に揺動自在に支持されるフラップ部材５１２を備えている。 The upper resin cover 51 includes a resin cover main body 511 attached to the inner peripheral recess 11f of the upper frame 11 and a flap member 512 swingably supported by the resin cover main body 511.

樹脂カバー本体５１１は、上枠１１の内周凹部１１ｆを形成する上枠本体部１１ａの内周面（内周凹部１１ｆの上面）を覆う上壁部５１１ａと、内周凹部１１ｆを形成する室内側見付壁部１１ｂの室外側面（内周凹部１１ｆの室内側面）を覆う室内側壁部５１１ｂと、内周凹部１１ｆを形成する中央見付壁部１１ｃの室内側面（内周凹部ｆの室外側）を覆う室外側壁部５１１ｃと、を備えている。 The resin cover main body 511 has an upper wall portion 511a that covers the inner peripheral surface (upper surface of the inner peripheral concave portion 11f) of the upper frame main body portion 11a that forms the inner peripheral concave portion 11f of the upper frame 11, and a chamber that forms the inner peripheral concave portion 11f. The indoor side wall portion 511b that covers the outdoor side surface (indoor side surface of the inner peripheral recess 11f) of the inner found wall portion 11b and the indoor side surface (outdoor side of the inner peripheral recess f) of the central found wall portion 11c that forms the inner peripheral recess 11f. ), And an outdoor wall portion 511c.

室内側壁部５１１ｂは、下端に、室内側見付壁部１１ｂの気密材保持部に載置係合可能な係合部を有し、係合部の近傍に軟質の合成樹脂材料によりなる室内側フラップ部５１１ｄが室外側に向けて延設されている。なお、樹脂カバー本体５１１は、室内側フラップ部５１１ｄ以外の部位は硬質の合成樹脂材料で形成されていることが好ましい。 The indoor side wall portion 511b has an engaging portion that can be placed and engaged with the airtight material holding portion of the indoor side finding wall portion 11b at the lower end, and the indoor side made of a soft synthetic resin material in the vicinity of the engaging portion. The flap portion 511d is extended toward the outdoor side. It is preferable that the resin cover main body 511 is made of a hard synthetic resin material except for the indoor flap portion 511d.

室外側壁部５１１ｃは、中央見付壁部１１ｃの室内側面を覆う第１中空部５１１ｅと、第１中空部５１１ｅの下端から室外側に延び中央見付壁部１１ｃの下面を覆う第２中空部５１１ｆと、第１中空部５１１ｅの下端から室内側に延びる第３中空部５１１ｇを有し、全体で逆Ｔ字状を成している。 The outdoor side wall portion 511c has a first hollow portion 511e that covers the indoor side surface of the central found wall portion 11c, and a second hollow portion that extends from the lower end of the first hollow portion 511e to the outdoor side and covers the lower surface of the central found wall portion 11c. It has a 511f and a third hollow portion 511g extending inward from the lower end of the first hollow portion 511e, and has an inverted T shape as a whole.

第１中空部５１１ｅの下方部位で第２中空部５１１ｆの上方に、中央見付壁部１１ｃの下端に形成された係合爪に係合する係合部５１１ｈが設けられている。
また、第３中空部５１１ｇの上面で第１中空部５１１ｅの下方位置に、フラップ部材５１２を揺動自在に支持するフラップ支持部５１１ｉが形成されている。 An engaging portion 511h that engages with an engaging claw formed at the lower end of the central found wall portion 11c is provided above the second hollow portion 511f at a lower portion of the first hollow portion 511e.
Further, a flap support portion 511i that swingably supports the flap member 512 is formed on the upper surface of the third hollow portion 511g at a position below the first hollow portion 511e.

室外側壁部５１１ｃの下面、すなわち第２中空部５１１ｆ、第３中空部５１１ｇの下面には、見込み方向に並ぶ２条のヒレ片が下方に向かって形成されており、２条のヒレ片は、外障子３の閉鎖時において、外障子３の上框３１の樹脂上框３１２に近接している。 On the lower surface of the outdoor wall portion 511c, that is, the lower surface of the second hollow portion 511f and the third hollow portion 511g, two fin pieces arranged in the prospective direction are formed downward, and the two fin pieces are formed. When the outer sash 3 is closed, it is close to the resin upper stile 312 of the upper stile 31 of the outer sash 3.

フラップ部材５１２は、下方室外側に形成された支持脚部５１２ｂと、支持脚部５１２ｂの室内側端から立ち上がる見付壁部５１２ｃと、見付壁部５１２ｃの上端から室内側に延びる見込壁部５１２ａとを有している。 The flap member 512 includes a support leg portion 512b formed on the outer side of the lower chamber, a found wall portion 512c rising from the indoor end of the support leg portion 512b, and a prospective wall portion extending inward from the upper end of the found wall portion 512c. It has 512a.

そして、フラップ部材５１２は、支持脚部５１２ｂの室外側端部が樹脂カバー本体５１１の室外側壁部５１１ｃの下方部位に形成されたフラップ支持部５１１ｉに揺動自在に支持されており、支持脚部５１２ｂの室内寄り下面が室外側壁部５１１ｃの第３中空部５１１ｇの上面に載置されることで、見付壁部５１２ｃが室外側壁部５１１ｃに対して所定間隔をあけて垂直状態に維持されるとともに、見込壁部５１２ａが上壁部５１１ａに対して所定間隔をあけて水平状態に維持される。 The flap member 512 is swingably supported by the flap support portion 511i formed at the lower portion of the outdoor wall portion 511c of the resin cover main body 511 at the outdoor end portion of the support leg portion 512b. By placing the lower surface of 512b closer to the room on the upper surface of the third hollow portion 511g of the outdoor wall portion 511c, the found wall portion 512c is maintained in a vertical state with a predetermined interval with respect to the outdoor wall portion 511c. At the same time, the prospective wall portion 512a is maintained in a horizontal state with a predetermined interval with respect to the upper wall portion 511a.

さらに、フラップ部材５１２の見込壁部５１２ａの室内側端部が樹脂カバー本体５１１の室内側フラップ部５１１ｄに近接することで上樹脂カバー５１の底壁部が形成され、上樹脂カバー５１は、樹脂カバー本体５１１とフラップ部材５１２とによって、室外側と上側に連続する断熱空間Ｓ１が形成されている。 Further, the indoor side end portion of the prospective wall portion 512a of the flap member 512 is close to the indoor side flap portion 511d of the resin cover main body 511, whereby the bottom wall portion of the upper resin cover 51 is formed, and the upper resin cover 51 is made of resin. The cover body 511 and the flap member 512 form a continuous heat insulating space S1 on the outdoor side and the upper side.

そして、上樹脂カバー５１を、上枠１１に配置するに際しては、上枠１１の内周凹部１１ｆに対して上樹脂カバー５１を下方から挿入することにより、樹脂カバー本体５１１の弾性により上樹脂カバー５１が変形して、室内側見付壁部１１ｂの気密材保持部と中央見付壁部１１ｃの下端に形成された係合爪との間を通過し、その後、室内側壁部５１１ｂの係合部が室内側見付壁部１１ｂの気密材保持部に係合するとともに、第１中空部の係合部５１１ｈが中央見付壁部１１ｃの係合爪に係合することで、上樹脂カバー５１を取付けることができる。 When the upper resin cover 51 is arranged in the upper frame 11, the upper resin cover 51 is inserted into the inner peripheral recess 11f of the upper frame 11 from below, and the upper resin cover is elastically covered by the elasticity of the resin cover main body 511. 51 is deformed and passes between the airtight material holding portion of the indoor side finding wall portion 11b and the engaging claw formed at the lower end of the central found wall portion 11c, and then the engagement of the indoor side wall portion 511b. The upper resin cover is formed by engaging the portion with the airtight material holding portion of the indoor side finding wall portion 11b and engaging the engaging portion 511h of the first hollow portion with the engaging claw of the central finding wall portion 11c. 51 can be attached.

内周凹部１１ｆに取り付けられた上樹脂カバー５１は、内周凹部１１ｆの内周面に金属部が露出しないように配置され、内周凹部１１ｆの上方部分及び室外側部分に連続する比較的大きな断熱空間Ｓ１を形成するので、障子の閉鎖時における外障子３の室内側の上枠１１における断熱性能を向上させることができる。 The upper resin cover 51 attached to the inner peripheral recess 11f is arranged so that the metal portion is not exposed on the inner peripheral surface of the inner peripheral recess 11f, and is relatively large and continuous with the upper portion and the outdoor side portion of the inner peripheral recess 11f. Since the heat insulating space S1 is formed, the heat insulating performance of the upper frame 11 on the indoor side of the outer shoji 3 when the shoji is closed can be improved.

そして、内障子２の建て込み時には、図５に示すように、内障子２の上端がフラップ部材５１２に当接することによってフラップ部材５１２は支持脚部５１２ｂを中心に回動するので、上樹脂カバー５１を硬質の合成樹脂材料により形成して比較的大きな断熱空間を形成しながら、内障子２の容易な建て込みを可能にしている。 When the internal sash 2 is built, as shown in FIG. 5, the upper end of the internal sash 2 comes into contact with the flap member 512, so that the flap member 512 rotates around the support leg portion 512b, so that the upper resin cover The 51 is formed of a hard synthetic resin material to form a relatively large heat insulating space, and the internal sash 2 can be easily built.

以上のように、本実施形態のサッシにおいては、内、外障子２，３の閉鎖時において室内に露出する上枠１１の外障子３の室内側部位に大きな断熱空間を備えた上樹脂カバー５１を配置しているので、断熱性能を向上させることができる。
しかも、上樹脂カバー５１の全ての部分もしくは大部分を硬質の合成樹脂材料によって形成することができるので、経時劣化による性能低下を抑えることができる。 As described above, in the sash of the present embodiment, the upper resin cover 51 having a large heat insulating space on the indoor side portion of the outer sash 3 of the upper frame 11 exposed indoors when the inner and outer sashes 2 and 3 are closed. Is arranged, the heat insulation performance can be improved.
Moreover, since all or most of the upper resin cover 51 can be formed of a hard synthetic resin material, deterioration in performance due to deterioration over time can be suppressed.

また、フラップ部材５１２を樹脂カバー本体５１１の下方部位に支持しているので、上樹脂カバー５１が内周凹部１１ｆ内に配置された際に樹脂カバー本体５１１に製造誤差等による多少の変形が生じた場合であっても、フラップ部材５１２の支持に影響を与えることが少ないので、フラップ部材５１２を適切な状態に維持することができ、広い断熱空間を確実に維持することができる。 Further, since the flap member 512 is supported in the lower portion of the resin cover main body 511, when the upper resin cover 51 is arranged in the inner peripheral recess 11f, the resin cover main body 511 is slightly deformed due to a manufacturing error or the like. Even in such a case, since the support of the flap member 512 is less affected, the flap member 512 can be maintained in an appropriate state, and a wide heat insulating space can be reliably maintained.

また、上樹脂カバー５１の底壁部を、室外側のフラップ部材５１２と室内側の室内側フラップ部５１１ｄとの二つの部材により構成することで、フラップ部材５１２の許容揺動角を大きくすることができ、内障子２のスムーズな建て込みを可能としている。さらに、上樹脂カバー５１の室内側フラップ部５１１ｄを軟質の合成樹脂で形成するとともに、見込み方向に短い幅で形成することにより、形成が容易であり、内障子２の建て込み時における破損を防止するとともに、室内側フラップ部５１１ｄのへたり等による断熱空間Ｓ１の変形を最小限に抑えることができる。 Further, by forming the bottom wall portion of the upper resin cover 51 with two members, the flap member 512 on the outdoor side and the flap portion 511d on the indoor side on the indoor side, the allowable swing angle of the flap member 512 is increased. This makes it possible to build the internal shoji 2 smoothly. Further, by forming the indoor flap portion 511d of the upper resin cover 51 with a soft synthetic resin and forming it with a short width in the prospective direction, it is easy to form and the internal obstacle 2 is prevented from being damaged when it is built. At the same time, it is possible to minimize the deformation of the heat insulating space S1 due to the sagging of the flap portion 511d on the indoor side.

なお、以上の実施形態は，請求項に記載された発明を限定するものではなく，例示として取り扱われることは言うまでもない。
例えば、本実施形態のサッシでは、上樹脂カバー５１の底壁部をフラップ部材５１２と室内側フラップ部５１１ｄにより形成したが、フラップ部材５１２のみによって形成してもよく、また、フラップ部材５１２と室内側フラップ部５１１ｄとが接触するようしてもよい。
また、フラップ部材５１２は、上樹脂カバー５１の室内側壁部５１１ｂの下方部位に揺動自在に支持してもよい。
また、サッシは、引違いサッシに限定されず、外障子がはめ殺しとなったサッシでもよい。 Needless to say, the above embodiments do not limit the invention described in the claims, and are treated as examples.
For example, in the sash of the present embodiment, the bottom wall portion of the upper resin cover 51 is formed by the flap member 512 and the indoor side flap portion 511d, but it may be formed only by the flap member 512, or the flap member 512 and the chamber. The inner flap portion 511d may be brought into contact with the inner flap portion 511d.
Further, the flap member 512 may be swingably supported on the lower portion of the indoor side wall portion 511b of the upper resin cover 51.
Further, the sash is not limited to the sliding sash, and may be a sash in which a shoji is fitted and killed.
