As described above, the force for closing the window 1 is generated by the drive shaft 9
The geared tape 11 is only pulled in by the rotation of the sprocket wheel 12. In addition, the automatic winder 18 includes the sprocket wheel 1
The geared tape 11 drawn by the rotation of 2 is simply taken up and wound up, and does not have to act as a window closing operation function.

Further, since the drive shaft body 9 performs both operations of releasing the engagement of the latch device and pulling the geared tape by rotating the sprocket wheel, it is not necessary to separately provide a mechanism for performing both functions. The window operator device can be made compact.

Further, the closed state of the window is held by the latch device, so that the window is securely held.

[Advantages of the Invention] According to the present invention, since the window operator device is provided with the latch device and the window returning device, it is possible to open and close the window with one drive shaft. Since a latch device consisting of an engaging element and a latch bolt is adopted as a means for closing and locking the window, when the window is closed, the closed state can be reliably maintained, and the closed state of the window can be maintained. Since it is not held by the tension of the geared tape, it is possible to prevent the geared tape from being stretched or cut while the window is closed.

A sprocket wheel 12 whose one end meshes with a geared tape 11 attached to the window
And a spur gear 13 that rotates coaxially and integrally with the sprocket wheel 12 and a spur gear 15 that meshes with the spur gear 13 and that coaxially rotates freely with the bevel gear 16. The bevel gear 17 that meshes with the bevel gear 16 and the coupler 10 that abuts the latch bolt 6 are provided so that the fixed drive shaft body 9 is slidable and rotatable, so that (1) the window is opened. At times, the latch device can be unlocked and the sprocket wheel can be freely rotated (idle) with only one operation of the drive shaft (movement in the direction of arrow A in the figure).
When the window is closed, the window can be pulled only by rotationally driving the drive shaft. As described above, the drive shaft 9 disengages the latch device and pulls the geared tape by rotating the sprocket wheel. Since the function operation is also performed, it is not necessary to separately provide a mechanism for performing both of these functions, and the window operator device can be made compact. (2) The geared tape has a length corresponding to the opening of the window. In addition, the length can be shortened, the housing can be made small, and the window closing operation can be performed in a shorter time than the conventional pulley and rope type,
Furthermore, if geared tape and sprocket wheels are adopted, a winding mechanism for them can be provided separately,
The accommodating portion can be a simple mechanism.
