  • Publication number: 20140305602
    Abstract: A battery-powered window treatment, such as a roller shade, may include a battery compartment that provides access to batteries while the window treatment is assembled and mounted to a structure. The battery compartment may be pivotally supported by a housing of the window treatment, and operable between opened and closed positions. The batteries may be concealed when the battery compartment is closed, and may be accessible when the battery compartment is open. The battery compartment may be operated opened and closed while a shade of the window treatment is at any position, such that removal of the batteries does not result in the loss of tracking information for the shade. The window treatment may include a fascia that is operably connected to the battery compartment, such that when the battery compartment is opened, the fascia does not obstruct access to the batteries, and does not interfere with the shade.

  • Patent number: 8857494
    Abstract: A window treatment may include one or more lift cord adjustment mechanisms for leveling of a bottom bar of the window treatment. The mechanisms may allow for fine-tuning adjustment of the levelness of the bottom bar. The mechanisms may be disposed at respective ends of the botom bar. The mechanisms may be directly accessible through the ends of the bottom bar. Each mechanism may include a pulley having a circumferential groove to receive a corresponding lift cord. A portion of the pulley may protrude relative to an exterior surface 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 appearance of the window treatment. Manual operation of a mechanism may adjust an amount of a corresponding lift cord that extends from the drive shaft to the pulley of the mechanism.

  • Patent number: 8851141
    Abstract: 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.

  • Patent number: 8723466
    Abstract: A motorized venetian blind system for covering a window of a space comprising a blind drive unit having two motors to provide for independent control of a position of a bottom rail and a tilt angle of a plurality of slats of the blind system. The blind drive unit is operable to adjust the position of the bottom rail to a preset position, and to adjust the tilt angle of the slats to a preset angle in response to receiving a single digital message (e.g., a preset command). The blind drive unit is operable to automatically adjust the position of the bottom rail and the tilt angle of the slats to limit a direct sunlight penetration distance in the space to a maximum direct sunlight penetration distance, and to maximum a reflected sunlight penetration distance on a ceiling of the space, while minimizing occupant distractions.

  • Publication number: 20130333849
    Abstract: 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.

  • Publication number: 20130240165
    Abstract: A motor drive unit assembly for a motorized drapery system having a drapery fabric can include a motor having a drive shaft, an output member rotatable about a drive axis, such that rotation of the output member about the drive axis causes the drapery fabric to move, and a clutch member operatively coupled between the drive shaft of the motor and the output member. The clutch member is configured to automatically couple the output member to the drive shaft such that rotation of the motor drive shaft causes the output member to rotate about the drive axis when the motor drives the drive shaft. The clutch member is further configured to automatically decouple the output member from the motor drive shaft so that the output member rotates about the drive axis relative to the motor drive shaft when the output member is manually driven.

  • Publication number: 20120261079
    Abstract: A motorized window treatment to automatically control the position of a covering material in front of a window to save energy. The motorized window treatment has an eco-mode whereby to at least one climate characteristic is measured by a sensor to save energy by decreasing the load on a heating and/or cooling system of the room in which the motorized window treatment is installed. The motorized window treatment opens the covering material on sunny winter days to allow energy from sunlight to be stored in the mass of the room, and closes the covering material at night to insulate the room and allow the energy from the sunlight stored in the mass of the room to heat the room and reduce the load on the heating and cooling system at night.

  • Publication number: 20120261078
    Abstract: 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.

  • Patent number: 8210229
    Abstract: 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 hembar contained within a hembar pocket of the shade fabric. The hembar is characterized by a non-linear shape, such as a serpentine shape, for causing the shade fabric to hang with a plurality of pleats. The hembar may comprise a plurality of C-shaped hembar sections flexibly coupled to each other. The 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 (e.g., serpentine) 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.
