A motorized window treatment system may include a roller tube, a flexible material, a motor drive unit, and mounting brackets. The mounting brackets may include a stationary portion configured to be attached to a structure surrounding a window. The mounting brackets may include a movable portion configured to receive an end portion of a housing of a motor drive unit. The movable portion may be configured to operate the motorized window treatment between the operating position and the extended position in a circular-shaped path. A portion of the motor drive unit may be accessible when the motorized window treatment is in the extended position. The mounting brackets may include a stopping mechanism that is configured to prevent the motorized window treatment from extending beyond the extended position.

A hold down device is provided for continuous loop cords or bead chains in a window covering installation. The hold down device engages the cord or chain while the cord or chain is loosely suspended, and prevents operation by encountering the head rail if the cord or chain is operated. Mounting the hold down device in a window covering installation disengages the hold down device from its secured position relative to the cord or chain.

Apparatuses and systems for selectively locking a lift cord designed to lift coverings for architectural openings is disclosed. The apparatus may comprise a selective locking member and a base member positioned at a bottom of an architectural opening covering. The base member and the selective locking member each have an opening through which a lift cord may pass. The selective locking member also has at least one edge configured to mate to a bottom of a groove in the base member. The selective locking member is configured to selectively engage the base member and the lift cord such that the selective locking member can be selectably moved between an open position, where the lift cord can be freely moved, and a closed position, wherein the selective locking member will pinch the lift cord between itself and the base member and prevent the lift cord from being moved.

Venetian blinds include a pair of slat lift and guide tapes (27, 28) that extend from the upper rail (12), downwardly through openings (22) in the elongated parallel slats (14) and into the lower rail (13) where they are collected in the lower rail on spools (48). The lift and guide tapes are concave in cross section when in their rectilinear shape and progressively change to flat in cross section as they are pulled into the lower rail and wrapped about tape collector spools.
