A drapery system that operates by rotating a rod having one, or a pair of left hand twist helical grooves, and one or a pair of right hand twist helical grooves, where the left hand twist and right hand twist helical grooves cross one another in equal spaced alignment across the length of the rotating rod. A plurality of idler rings and at least one driver ring are positioned around the drapery rod. The idler rings have a smooth interior surface whereas the driver rings include at least one tooth that engages a helical groove of the rotating rod. As the rotating rod is rotated, the driver ring is driven across the length of the rotating rod, thereby opening and closing the system. The system also includes a mounting bracket allows for extending the drapery past the inward edge of the inward most ring.

A window shade may include a shade, a sliding base, a weight track, a first blocking unit, and two second blocking units. The shade has two mount bars respectively formed at an upper end and a lower end thereof, and the shade is connected to the sliding base and the weight track through the two mount bars. The position of the sliding base is limited by the first blocking unit while the second blocking units are configured to limit the position of the weight track. With the first blocking unit and the two second blocking units, the shade can be replaced easily, and also the structural stability of the window shade is improved.

A cordless motorized roller shade includes a motorized operation device, a shading device mounted on the motorized operation device and hanging down, and a combination module detachably mounted between the motorized operation device and the shading device. Thus, the roll cloth member of the motorized operation device is pressed by the holding units of the shading device so that the roll cloth member is kept at a straight state smoothly when hanging down. In addition, when the roll cloth member is moved upward, the rotary return wheel module of the motorized operation device aids the upward movement of the roll cloth member to reduce consumption of the electric power of the drive motor of the motorized operation device during operation so that the roll cloth member is folded upward in an energy-saving manner.

A hembar may define a front portion and a rear portion configured to slidably engage each other. The front portion and the rear portion, when slidably engaged, may define a slot configured to receive a piece of fabric. The front portion and the rear portion may be configured to clamp the piece of fabric within the slot. The front portion and the rear portion may be configured such that a width of the slot is adjustable. The front portion may define a first attachment surface and the rear portion may define a second attachment surface. The first attachment surface may define a rib. The second attachment surface may define a groove configured to receive the rib when the front portion is slidably engaged with the rear portion such that the piece of fabric is clamped within the slot.
