Abstract: An improvement of roller blinds controller is provided, it mainly comprises a cylindrical rod passing through a side cover and fixing therewith; a bead chain sprocket and a number of torsion springs fitted on the cylindrical rod, and an outer sleeve cover fitted on the outside, wherein: the cylindrical rod has a ridge portion protruded from the circumferential surface thereof, while the side cover has a has a central aperture with a annular edge portion, the cylindrical rod can be fixed with the side cover by the snap-fitting of the annular edge portion between the flange portion and the ridge portion.

Abstract: A curtain control assembly includes a shaft in which a torque rod and a control unit are received. The curtain is wrapped around the shaft. The control unit has a frame from which a tubular portion extends. The tubular portion has a polygonal protrusion. An end support is located in the frame and has a hook which is hooked to the control unit. A bead-chain disk is mounted to the tubular portion. A mount is mounted to a sleeve of the bead-chain disk. A connection member is fixed to the torque rod and a polygonal recess is defined in the connection member. The protrusion is engaged with the recess. A screw extends through the connection member, the tubular portion and is fixed to the end support. The feed-back of torque from the torque rod is shared by the polygonal recess and protrusion to protect the hook from being broken.

Abstract: A glider unit for pleated curtain comprises a sliding carriage and a fastener. The sliding carriage has a female snap-fit portion provided at its bottom for engaging with the fastener. The fastener has a combining section for fixing with a curtain fabric. The outer edge of the female snap-fit portion is formed as an arc segment, whereby the curtain fabric can be compliant with the arc segment so as to form regularly pleated pattern and smooth fabric surface during the closing of the curtain. Two pulleys pivotally coupled by a shaft are respectively mounted at both sides of each sliding carriage for moving on a curtain track. A plurality of balls are disposed between each pulley and the shaft so as to facilitate the rolling of each pulley without much application of force, so that opening and closing of the curtain can be accomplished in less laborious effort required.

Abstract: A slat winding and unwinding control device of window blind includes flexible snap fit portions that are provided on the base to engage directly into the upper beam so that the mounting of the base into the interior of the upper beam is easy.
