Definitions
- the subject of the invention is a winding device for blind hanging cord including a drum winding, on which is fixed the end of at minus a hanging cord, and means for ensure a winding of the cord in regular turns without overlap.
- the turns are formed resting against a side face of the sliding nut. If the thread pitch is equal to or greater than the diameter of the cord, it is then wound in regular turns without overlap.
- Figure 1 is a partial view in axial section according to I-I of FIG. 2, of a winding drum of blind in a position close to the winding full.
- Figure 2 is a cross-sectional view along II-II of Figure 1.
- the winding device shown comprises a box or box 1 of rectangular parallelepipedic shape open upwards and fitted with two flanges end, such as the flange 2, supporting a motor tubular 3 whose casing 4 carries and drives in rotation of a winding drum 5 provided with a screw in engagement with a square nut 6 sides of length very slightly less than the inner width of the housing 1, so that the sliding nut 6 is immobilized in rotation but that it can move along the winding drum 5 when rotating it.
