  • Patent number: 9810020
    Abstract: A motorized window treatment may provide a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment may include a covering material (e.g., a cellular shade fabric or a roller shade fabric), a drive assembly for raising and lowering the covering material, and a motor drive unit including a motor configured to drive the drive assembly to raise and lower the covering material. The motorized window treatment may comprise one or more battery packs configured to receive batteries for powering the motor drive unit. The batteries may be located out of view of a user of the motorized window treatment (e.g., in a headrail or in a battery compartment). The motorized window treatment may use various power-saving methods to lengthen the lifetime of the batteries, e.g., to reduce the motor speed to conserve additional battery power and extend the lifetime of the batteries.

  • Publication number: 20170260806
    Abstract: A motorized window treatment provides a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment includes a covering material, a drive shaft, at least one lift cord rotatably received around the drive shaft and connected to the covering material, and a motor coupled to the drive shaft for raising and lowering the covering material. The window treatment also includes a spring assist unit for assisting the motor by providing a torque that equals the torque provided by the weight on the cords that lift the covering material at a position midway between fully-open and fully-closed positions, which helps to minimize motor usage and conserve battery life if a battery is used to power the motorized window treatment. The window treatment may comprise a photosensor for measuring the amount of daylight outside the window and temperature sensors for measuring the temperatures inside and outside of the window.

  • Patent number: 9745796
    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.

  • Publication number: 20170183909
    Abstract: A motorized window treatment system may include a roller tube, a covering material windingly attached to the roller tube, and a drive assembly that may be at least partially disposed within the roller tube. The drive assembly may include a motor having a drive shaft that is elongate along a longitudinal direction and a drive gear attached to the drive shaft such that a toothed portion of the drive gear is cantilevered with respect to the drive shaft. The drive assembly may include a gear assembly having a pair of intermediate gears on opposed sides of the drive gear. Rotation of the drive gear may be transferred through the pair of intermediate gears, a connecting gear, a planetary gear set, a cage, and an idler to the roller tube. Rotation of the roller tube may cause the covering material to move between an open position and a closed position.

  • Publication number: 20170044824
    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 supported along a pivot axis by a housing of the window treatment, and operable between opened and closed positions by pivoting the battery compartment about the pivot axis. 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 define a central axis that is offset relative to the pivot axis, and along which the batteries may be aligned. 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.

  • Publication number: 20160369558
    Abstract: A variable resistance brake may be operably coupled to a window treatment, such as to the roller tube of a motorized roller shade. The variable resistance brake may generate a first braking force that resists rotation of the roller tube in a first rotational direction, and a second braking force that resists rotation of the roller tube in a second rotational direction. The first and second braking forces may have different magnitudes. The variable resistance brake may include an idler, a mandrel that is operably coupled to the idler, a spring that rides on the mandrel, and a bearing that is configured to operably engage with the roller tube and that is rotatable about the idler. The idler may be configured to be supported in a fixed position relative to the roller tube. The spring may define a first end that is fixed in position relative to the bearing.

  • Publication number: 20160326801
    Abstract: A low-deflection roller tube of a motorized roller shade may have an outer diameter that does not exceed 2 inches. When a covering material is attached to the roller tube and the roller tube is supported at opposed ends thereof, deflection of a 10 foot configuration of the roller tube may not exceed ? of an inch, and deflection of a 12 foot configuration of the roller tube may not exceed ΒΌ of an inch, relative to corresponding unloaded positions of the roller tubes. The roller tube may comprise a plurality of layers of carbon fiber, or may comprise an inner tube that is made of a first material, such as aluminum, and a carbon fiber outer tube that is formed on the inner tube. At least one layer, such as an outermost layer, may comprise high modulus carbon fiber.
