The case 10 has a front side 12 at a front and a rear side 14 at a rear (FIG 6), which are vertical planes and parallel to an elongated axis of the case 10. A distance between the front side 12 and the rear side 14 (so called a width of the case 10) is defined as a first distance Li. The rail 20 is received in the case 10 and fixed therein, therefore the rail 20 is fixed to the window frame 100A (or the wall) through the case 10. The case 10 provides a space between the wall and the sashes 30, 40 for the sashes 30, 40 to turn and move.
The rail 20 is exposed via the bottom opening of the case 10. The rail 20 is an elongated hollow member with a rail opening 26 at a bottom thereof. The rail 20 has a first end 20a and a second end 20b at opposite ends, and the rail 20 is straight from the first end 20a to the second end 20b. The rail 20 further has a front side 22 and a rear side 24, which are vertical planes and parallel to an elongated axis of the rail 20. A
distance between the front side 22 and the rear side 24 (so called a width of the rail 20) is defined as a second distance L2, and the second distance L2 is shorter than the first distance Li. The rail 20 is closer to the front side 12 of the case 10 than the rear side 14, so that a space S is left between the rear side 24 of the rail 20 and the rear side 14 of the case 10.
The first and the second sashes 20, 40 are hinged with each other by two hinges 50, so that they may be moved between an extended condition and a folded condition. A pivoting base 32 is fixed to a rear side 30a of the first sash 30 and adjacent to a top of the first sash 30. The pivoting base 32 has a vertical bore 32a. A
