A window treatment includes mechanisms allowing for easy leveling of a bottom bar of the window treatment without the use of tools and without requiring any portion of the window treatment to be disassembled. The mechanisms allow for incremental adjustment of the amounts of each of two lift cords that extend from the bottom bar to a drive shaft to thus provide fine-tuning adjustment of the levelness of the bottom bar. The mechanisms may be hidden from view on the sides of the bottom bar, such that the mechanisms do not detract from the attractive, aesthetically pleasing appearance of the window treatment. Each lift cord extends from the drive shaft to a pulley of the respective mechanism and wraps around the pulley, such that the amount of the lift cord that extends from the drive shaft to the mechanism may be adjusted in response to rotations of the pulley.

A tensioned roller shade system for installation in an opening, such as a window or a skylight, comprises a frame, a roller tube rotatably mounted between side channels of the frame adjacent a first end of the frame, a conical, grooved spool mounted adjacent the roller tube, and a shade fabric is windingly received around the roller tube. A tensioning cord is operatively coupled between the spool and a fabric end of the shade fabric. The spool has a single groove, which wraps around the spool and windingly receives about the tensioning cord. A pulley is operatively coupled to the frame adjacent a second frame end and windingly receives the tensioning cord. The tensioning cord is adapted to bias the second fabric end toward the second frame end, such that the second fabric end of the shade fabric is adapted to move between the first and second frame ends as the roller tube is rotated.

A pleated roller shade system allows a thin flexible shade fabric, such as, for example, silk, to be wrapped around a roller tube. The pleated roller shade system comprises a drive system, such as a motor or manual drive system, for controlling of the rotation of the roller tube. The roller shade system may comprise a pleating hem bar that is contained within a hem bar pocket of the shade fabric and has a non-linear shape for causing the shade fabric to hang with a plurality of pleats. The roller shade system may also comprise an elongated pleating assembly mounted parallel to the roller tube and having a fabric-receiving opening that defines a non-linear path. The shade fabric may be received through the fabric-receiving opening and folded by the pleating assembly, such that the shade fabric is wrapped around the roller tube in folds as the roller tube rotates. The pleating assembly includes a plurality of pleating elements that each have a T-shaped or funnel-shaped structure for causing the shade fabric to hang with the pleats.

A drapery system for moving a suspended drapery fabric allows the drapery fabric to be decoupled from a drive system, such that the drapery fabric may be manually moved. The drapery system comprises a master car comprising a driven portion and a non-driven portion. The driven portion is coupled to a drive belt of the drive system, while the non-driven portion is coupled to the drapery fabric. The master car comprises a spring having a snap adapted to be received in a snap-receiving structure, such that the driven portion is coupled to the non-driven portion. The non-driven portion is operable to move in response to movement of the drive belt to move the drapery fabric when the non-driven portion is coupled to the driven portion. The non-driven portion is operable to be decoupled from the driven portion, such that the position of the drapery fabric may be manually adjusted.

A battery-powered motorized window treatment for covering at least a portion of a window may be adjusted into a service position to allow for access to at least one battery that is powering the motorized window treatment. A headrail of the motorized window treatment may be adjusted to the service position to allow for easy replacement of the batteries without unmounting the headrail and without requiring tools. The motorized window treatment may comprise brackets having buttons that may be actuated to release the headrail from a locked position, such that the head rail may be rotated into the service position. The headrail easily rotates through a controlled movement into the service position, such that a user only needs one free hand available to move the motorized window treatment into the service position and change the batteries.

A pleated roller shade system allows a thin flexible shade fabric, such as, for example, silk, to be wrapped around a roller tube. The system comprises a pleating bar mounted parallel to the roller tube and having a fabric-receiving opening that defines, for example, a serpentine path. The shade fabric is received through the fabric-receiving opening and is folded by the pleating bar, such that the shade fabric is wrapped around the roller tube in folds as the roller tube rotates. The shade fabric is neatly wrapped around the roller tube (i. e. , bunching of the shade fabric is avoided) and is stored out-of-sight when rolled up.

A manual roller shade system includes a rotatably-mounted roller tube, a flexible shade fabric windingly received around the roller tube, and first and second elongated telescoping structures that allow for rotating the roller tube for manually raising and lowering the shade fabric. The roller shade system also has a clutch mechanism coupled to the roller tube, and a drive chain coupled to the clutch mechanism. The first and second elongated telescoping structures receive first and second end portions of the drive chain, respectively, and are connected to the first and second telescoping structures, such that the roller tube rotates in the first angular direction to raise the shade fabric when the first telescoping structure is pulled downward, and in the second angular direction to lower the shade fabric when the second telescoping structure is pulled downward.

A motorized window treatment controls daylight entering a space through a window and includes a covering material, a drive shaft, lift cords received around the drive shaft and connected to the covering material, and a motor coupled to the drive shaft. It also includes a spring assist unit for the motor providing a torque that equals the torque provided by the weight on the lift cords at a position midway between fully-open and fully-closed positions, minimizing motor usage and conserving battery life. A photosensor for measuring the daylight outside the window and temperature sensors for measuring the temperatures inside and outside of the window may be provided. The position of the covering material is automatically controlled to save energy, or may also be controlled in response to an infrared or radio-frequency remote control.
