上枠１１に取り付けられるケース体５１は、合成樹脂材料からなり、図１（ｂ）に示すように、上枠１１のアングル部１１３の内周面に当接される外周壁部５１ａと、外周壁部５１ａの室外側端から下方に延びる外周側室外壁部５１ｂと、外周壁部５１ａの室内側端から下方に延び下方部分が室外側に傾斜する傾斜面として形成されている室内壁部５１ｃと、室内壁部５１ｃの下端から室外側に延びる内周壁部５１ｄと、内周壁部５１ｄの室外側端から上方に延びる内周側室外壁部５１ｅと、内周側室外壁部５１ｅの上端から室内側に向かって延びる固定壁部５１ｆを有し、全体として断熱材６１を収容する収容空間Ｓを形成している。   The case body 51 attached to the upper frame 11 is made of a synthetic resin material, and as shown in FIG. 1B, an outer peripheral wall portion 51 a contacting the inner peripheral surface of the angle portion 113 of the upper frame 11 and an outer peripheral wall portion 51 a. An outer peripheral side outdoor wall portion 51b that extends downward from the outdoor side end of the wall portion 51a, and an indoor wall portion 51c that extends downward from the indoor side end of the outer peripheral wall portion 51a and the lower portion is formed as an inclined surface that inclines toward the outdoor side. , An inner peripheral wall portion 51d extending from the lower end of the indoor wall portion 51c to the outdoor side, an inner peripheral side outdoor wall portion 51e extending upward from the outdoor side end of the inner peripheral wall portion 51d, and an inner peripheral side outdoor wall portion 51e from the upper end to the indoor side. It has the fixed wall part 51f which extends toward, and forms the accommodation space S which accommodates the heat insulating material 61 as a whole.

そして、ケース体５１は、外周側室外壁部５１ｂと固定壁部５１ｆとの間に収容空間Ｓに連続する開口部ａが形成されており、図１（ｃ）に示すように、開口部ａを介して真空断熱材等の断熱材６１を収容することができる。そして、断熱材６１は、内周部分を障子２の上框２１に近接させて覆うことができるので、障子２の室内側を通って冷熱が伝達することを抑制することができ、断熱性を向上させることができる。
また、ケース体５１の内周壁部５１ｄの室外側から室外側方向に向かって突片５１ｇが形成されている。なお、突片５１ｇは、ケース体５１と同じ硬質の合成樹脂材料によって形成されてもよいが、軟質の合成樹脂材料によって形成されていてもよい。 Then, the case body 51 has an opening a that is continuous with the accommodation space S between the outer peripheral side outdoor wall 51b and the fixed wall 51f, and as shown in FIG. A heat insulating material 61 such as a vacuum heat insulating material can be accommodated in the space. And since the heat insulation material 61 can cover the inner peripheral part in proximity to the upper frame 21 of the shoji screen 2, it is possible to suppress the transfer of cold heat through the indoor side of the shoji screen 2 and to improve the heat insulating property. Can be improved.

また、ケース体５の断面形状も各枠体に応じて異なる断面形状のものであってもよい。 Further, the materials and shapes of the upper frame, the lower frame, and the left and right vertical frames to which the case body 5 is attached are not limited. For example, the frame body may be made of synthetic resin or aluminum alloy, or may be a composite sash thereof. Further, the frame body does not have to have the same cross-sectional shape, and may not have the angle portion. In that case, the case body may be brought into contact with the inner peripheral surface of the body, and an adhesive agent such as caulk may be applied over the body and the case body.
Also, the cross-sectional shape of the case body 5 may be different depending on each frame body.

また、ケース体５に収容される断熱材６は、真空断熱材に限定されるものではなく、例えば発泡プラスチック系断熱材を用いることもでき、場合によっては、断熱材を収容しなくてもよい。
また、収容する断熱材６１は、収容空間Ｓの形状に合わせて形成されたものでもよいが、所定の寸法を有する断熱材を適宜個数収容してもよく、その際に、寸法及び材質の異なる複数種類の断熱材を配置してもよい。収容する断熱材６１所定の寸法とすることで、コストダウンができ、また、開口部から収容することで施工性も良い。さらに、真空断熱材以外の切断可能な断熱材を用いることによっても、施工性を向上させることができる。
さらに、断熱材６１は、開口部ａからケース体５１の内面に発泡断熱剤を吹き付けることによって形成（収容）してもよい。 Further, the heat insulating material 6 housed in the case body 5 is not limited to the vacuum heat insulating material, and for example, a foamed plastic heat insulating material may be used, and in some cases, the heat insulating material may not be housed. .
Further, the heat insulating material 61 to be housed may be formed according to the shape of the housing space S, but an appropriate number of heat insulating materials having a predetermined size may be housed, in which case the size and the material are different. Plural kinds of heat insulating materials may be arranged. The heat insulating material 61 to be accommodated has a predetermined size, so that the cost can be reduced, and the workability is good because it is accommodated from the opening. Further, the workability can be improved by using a heat insulating material that can be cut, other than the vacuum heat insulating material.
Furthermore, the heat insulating material 61 may be formed (stored) by spraying a foamed heat insulating agent onto the inner surface of the case body 51 from the opening a.

また、ケース体５は、既設の建具の枠体に対して、後付けによって取り付けられるものであってよい。ケース体５の取付には、構造用両面テープ等を用いることができるが、接着剤による接着でもよく、さらには、面ファスナー等の取付手段によって取り付けても良く、何ら限定されるものではない。   The case body 5 may be attached to the frame of an existing fitting by retrofitting. A structural double-sided tape or the like can be used to attach the case body 5, but the case body 5 may be attached by an adhesive, or may be attached by an attaching means such as a surface fastener, and is not limited in any way.

さらに、断熱建具は、開き窓やすべり出し窓、ＦＩＸ窓に限定されるものではなく、引違い窓等建具の種類は何ら限定されるものではない。
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。 Furthermore, the heat insulating fittings are not limited to open windows, sliding windows, and FIX windows, and the types of fittings such as sliding windows are not limited at all.
