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.

Abstract: A battery-powered Roman shade system may comprise first and second brackets for mounting the shade system to a structure, a roller tube rotatably supported by the first and second brackets, and a housing configured to receive, at a first end of the housing, one or more batteries for powering a motor drive unit inside the roller tube.

The position of the covering material may be automatically controlled in response to the photosensor and the temperature sensors, or in response to an infrared or radio-frequency remote control.
