Winding device for cordless roman shade

Abstract

A winding device for a cordless Roman shade includes an upper frame. A shade includes an upper end engaged with a side of the upper frame. A resilient winding mechanism is directly or indirectly coupled to the upper frame. A winding cloth includes an upper end engaged with a distal end of a winding route of the resilient winding mechanism. The winding cloth further includes a lower end engaged with a lower end of the shade. When the resilient winding mechanism moves in a winding direction, the winding cloth is wound, and the shade is folded. By providing the winding cloth for folding the shade, strangling by the winding cloth is less likely to occur, providing enhanced safety.

1 . A winding device for a cordless Roman shade comprising:
 an upper frame including a first side;   a first shade including an upper end engaged with the first side of the upper frame, with the first shade further including a lower end;   a resilient winding mechanism directly or indirectly coupled to the upper frame; and   a winding cloth including an upper end engaged with a distal end of a winding route of the resilient winding mechanism, with the winding cloth further including a lower end engaged with the lower end of the first shade;   wherein when the resilient winding mechanism moves in a winding direction, the winding cloth is wound, and the first shade is folded.   
     
     
         2 . The winding device for a cordless Roman shade as claimed in  claim 1 , further comprising: a second shade including an upper end, with the upper frame including a second side opposite to the first side, with the upper end of the second shade engaged with the second side of the upper frame, with the second shade having a portion connected to the first shade, with the second shade is folded when the winding cloth is wound while the resilient winding mechanism moves in the winding direction. 
     
     
         3 . The winding device for a cordless Roman shade as claimed in  claim 2 , with the portion of the second shade connected to the first shade by a plurality of connecting members spaced in a vertical direction, with each of the plurality of connecting members having a first end connected to an inner face of the first shade and a second end connected to an inner face of the second shade, with a space defined by each of the plurality of connecting members, with the winding cloth extending through the spaces defined by the plurality of connecting members. 
     
     
         4 . The winding device for a cordless Roman shade as claimed in  claim 1 , with the winding cloth having a width of at least 10 cm. 
     
     
         5 . The winding device for a cordless Roman shade as claimed in  claim 1 , with a channel formed in a front edge of each of the plurality of connecting members, with a rod extending through each of the channels, reinforcing a regular wound state of the first shade of balanced upward or downward movement.
