However, a plurality of members each having a short width in the finding direction may be provided. The vertical frame joining member 37 and the fixing bracket 90 attached to the refurbished vertical frame 23 may be provided in the entire region in the vertical direction, or a plurality of members each having a short vertical width may be provided. .

上記実施形態においては、既設枠50の室外側に間隔を隔て、開口2にて室内側の領域と室外側の領域とを区画可能な雨戸5としたが、これに限るものではない。例えば、図8、図9に示すような、シャッターボックス6aとシャッターレール6bとを備え、開口をシャッターカーテン6cにより開閉自在なシャッターユニット6や、図10、図11に示すような面格子7が設けられた施工箇所にも容易に取り付けることが可能である。特に、面格子7は、外壁や躯体に固定されているので、常に開口2を覆っている。このため、本改装サッシユニット1のように、室内側から取り付けられ、改装サッシを取り付ける際に、面格子7と既設枠50の既設網戸上レール51c及び既設網戸下レール52cとの間の空間より室外側に突出することなく改装枠20、120を室内側から取り付けることにより、面格子7を取り外すことなく改装サッシユニット1を容易に取り付けることが可能である。   In the above-described embodiment, the shutter 5 is configured to partition the indoor region and the outdoor region at the opening 2 with an interval between the outdoor side of the existing frame 50, but is not limited thereto. For example, a shutter unit 6 having a shutter box 6a and a shutter rail 6b as shown in FIGS. 8 and 9 and having an opening that can be opened and closed by a shutter curtain 6c, or a surface grid 7 as shown in FIGS. It is possible to easily attach to the construction site provided. In particular, since the surface lattice 7 is fixed to the outer wall or the casing, it always covers the opening 2. For this reason, like this remodeled sash unit 1, it is attached from the indoor side, and when the refurbished sash is installed, from the space between the face grid 7 and the existing screen door upper rail 51c and the existing screen door lower rail 52c of the existing frame 50 By attaching the modified frames 20 and 120 from the indoor side without projecting to the outdoor side, the modified sash unit 1 can be easily attached without removing the face grid 7.

また、上記実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。本発明は、その趣旨を逸脱することなく、変更、改良され得ると共に、本発明にはその等価物が含まれることはいうまでもない。   Moreover, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
