ている。2. Description of the Related Art There is a double sash in which individual sashes are attached to an outdoor side and an indoor side of a window in order to enhance heat insulation and sound insulation of the window. Since the estimated width of the wooden frame (wooden frame) forming the window opening is not constant, when the window frames of the inner and outer sashes are installed, the window frame of the inner sash is installed at the indoor side end of the window frame of the outer sash. In some cases, it may not be possible to attach the outer end in close contact. For this reason, in order to prevent the wooden frame from being exposed between the window frames and damaging the interior of the windows, and to prevent dew condensation on the building frame from the gap between the window frames, the double frame has conventionally been used. A connecting frame that connects sash window frames is used.

あった。However, since the conventional connecting frame is not formed in consideration of the dimensional relationship with the window frame of the outer sash, it is assembled in a rectangular shape in advance, and the outer sash after the mounting is mounted. Since it cannot be carried into the window frame and mounted, the upper and lower frames and the left and right vertical frames that constitute the connecting frame are individually loaded into the outer sash window frame, individually mounted, and finally a rectangular ring However, there was a problem that installation was troublesome and time-consuming.

にずれが生じる恐れもあった。Therefore, each frame 31, 32, 3 of the connecting frame F3
If the connecting frames 3 and 33 are previously connected in a rectangular shape, the outer peripheral dimension along the outer peripheral surface of the connecting frame is larger than the inner peripheral dimension formed by the inner peripheral surface of the outer sash window frame F1. Cannot be inserted from either the indoor side or the outdoor side of the outer sash window frame. Thus, conventionally, each frame 31, 32, 3
3 are individually attached, the outer connecting portions of the respective frames are fitted and locked to the inner peripheral edges of the indoor side end surfaces of the upper and lower frames and the vertical frames of the outer sash window frame, and screws are attached from the inner connecting portions to the window frame. Are screwed into the upper and lower frames 41, 42 and the vertical frame 43, respectively, so that the frames 31 to 33 are continuous in a rectangular shape. After the connection frame F3 is attached, the window frame F2 of the inner sash is inserted from the indoor side into the inside of the window wooden frame, and the outdoor portion of the window frame F2 is telescopically fitted into the inside connection portion of the connection frame F3. Then, the window frame F2 was fixed with screws. For this reason, as described above, conventionally, it takes time and effort to mount the connecting frames, and there is a possibility that the mounting positions of the frames may shift.
