  • the winding device 40 further includes at least three shafts 46 each rotatably mounted thereon with the cord spool 43, the first drum 44, or the second drum 45 having two ends fixed to two opposite walls of the housing 41.
  • a band spring 47 connects the first drum 44 and the second drum 45.
  • the band spring 47 has two winding portions 471 and 472 which together form an S.
  • the band spring 47 can exert a force to absorb the weight of the web from drapery material 30.
  • a free end 48 of the winding section 472 is mounted on the first drum 44.
  • a long cord 13A is wound around the cord spool 43.
  • the winding direction of the cord 13A is the same as that of each of the winding portions 471 and 472.
  • One end of the cord 13A leads through one of two slots 411 on a side surface of the housing 41 to contact the leash or string 49 at a loop portion 491 which abuts the end of the cord 49 is adapted to couple.
  • the cord spool 43 has at one end a gear 412 which meshes with a gear 413 of the first drum 44 such that the spool 43 and the first drum 44 can rotate in opposite directions.
  • the S-shaped band spring 47 is stretched due to the same winding direction of the winding sections 471 and 472 and the weight of the web of drapery material 30.
  • Manual pulling down of the stiffening bar 20, together with the weight of the sheet of drape material 30, can overcome an upward pulling force of the cord 13A created by the ribbon spring 47.
  • the cord coil 43 as such rotates to release the cord 13A, and thus the cord 49, so as to lower the web of drape material 30.
  • the winding portion 472 is further wound to store spring energy while the winding portion 471 is released to compensate for further winding of the winding portion 472 during release. This serves as a counterbalance to the web of drape material 30 so as to achieve balance.
  • the web of drape material 30 is designed to remain in any of a variety of positions from the fully raised position to the fully lowered position by stopping the cord coil 43.
