上記特許文献１に記載されたサッシは、アングル部の室外側に枠体に連結する取付壁部を枠体の室内側面に係合等することでアングル部材が枠体に取り付けられている。
このようなサッシは、サッシ本体にアングル部材を取り付けた状態で施工現場へ搬送することが効率的であるが、サッシの搬送時に樹脂製のアングル部材が外れないようにサッシ本体に対するアングル部材の係合を強固にする必要があった。
しかし、アングル部材のサッシ本体に対する係合が強固であると、例えばアングル部材に経年劣化等による破損や汚れが生じたときに、アングル部材を簡単に交換することができず、交換に手間がかかる可能性があった。 In the sash described in Patent Document 1, the angle member is attached to the frame body by engaging the mounting wall portion connected to the frame body on the outdoor side of the angle portion with the indoor side surface of the frame body.
It is efficient to transport such a sash to the construction site with the angle member attached to the sash body, but the angle member is engaged with the sash body so that the resin angle member does not come off when the sash is transported. It was necessary to strengthen the case.
However, if the angle member is firmly engaged with the sash body, for example, when the angle member is damaged or soiled due to deterioration over time, the angle member cannot be easily replaced, and it takes time and effort to replace the angle member. There was a possibility.

本発明は、上記の事情を鑑み、枠体の室内側に樹脂製のアングル部材が取付られたサッシについて、サッシの搬送時にアングル部材が容易に外れることなく、施工後には、アングル部材を容易に交換可能とすることを目的とする。 In view of the above circumstances, the present invention has a sash in which a resin angle member is attached to the indoor side of the frame, and the angle member does not easily come off during transportation of the sash, and the angle member can be easily removed after construction. The purpose is to make it replaceable.

The mounting wall portion has a mounting wall portion that can be engaged with the portion, and the mounting wall portion has an engaging portion that engages with the frame body and a tearable free portion formed on the angle portion side from the engaging portion. The torn free portion is a sash that can be cut by pulling the angle portion toward the inner peripheral side of the frame body while the engaging portion is engaged with the frame body .

本発明の一実施形態のサッシの構成により、サッシの搬送時にアングル部材が容易に外れることなく、施工後には、アングル部材を容易に交換することができる。 According to the configuration of the sash according to the embodiment of the present invention, the angle member can be easily replaced after the construction without the angle member being easily disengaged during the transportation of the sash.

After that, as shown in FIG. 11D, the angle member 61 can be replaced by fixing the angle portion 61b to the skeleton opening by a fixing means such as a nail.

以上のように、本発明の各実施形態のサッシにおいては、上枠１１に対してアングル部材６１を強固に取り付けることができ、上枠１１の搬送中にアングル部材６１の容易な脱落を防止することができながら、アングル部材６１の交換時には、アングル部材６１を上枠１１から容易に取り外すことができ、交換作業の効率化を図ることができる。 As described above, in the sash of each embodiment of the present invention, the angle member 61 can be firmly attached to the upper frame 11 and the angle member 61 is prevented from easily falling off during the transportation of the upper frame 11. However, when the angle member 61 is replaced, the angle member 61 can be easily removed from the upper frame 11, and the efficiency of the replacement work can be improved.

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、アングル部材６１に形成された引きちぎり自在部６１ｎは、部材の厚さを小さくして形成されるものに限定されず、部材に傷等を設けるなどして形成された他の部分よりも強度の弱い部分や、折り曲げ部等のアングル部材６１を引っ張った時に力が集中する部分によって構成してもよい。
また、サッシは、引違いサッシに限定されるものではなく、アングル部材を用いるあらゆるサッシに対して適用することができる。 Needless to say, the above embodiments do not limit the invention described in the claims, and are treated as examples.
For example, the torn free portion 61n formed on the angle member 61 is not limited to the one formed by reducing the thickness of the member, and is more than the other portion formed by providing scratches or the like on the member. It may be composed of a portion having a weak strength or a portion where a force is concentrated when the angle member 61 such as a bent portion is pulled.
Further, the sash is not limited to the sliding sash, and can be applied to any sash using an angle member.
