A motorized window treatment may include a roller tube, a flexible material attached to the roller tube, a motor drive unit, and mounting brackets configured to rotatably support respective ends of the roller tube. The roller tube may be operable between an operating position and an extended position. The extended position may include one or more ends of the roller tube being accessible while still attached to the mounting brackets. At least one of the mounting brackets may include a stationary portion, a sliding portion, and/or a translating portion. The translating portion and/or the sliding portion may be configured to translate the roller tube between the operating position and the extended position. The translating portion may define an attachment member and include an attachment aperture. The end of the roller tube may be accessible via the attachment aperture when the roller tube is in the extended position.

Battery-operated window treatment

A control system may include a direct-current (DC) power bus for charging (e.g., trickle charging) internal energy storage elements in control devices of the control system. For example, the control devices may be motorized window treatments configured to adjust a position of a covering material to control the amount of daylight entering a space. The system may include a DC power supply that may generate a DC voltage on the DC power bus. For example, the DC power bus may extend from the DC power supply around the perimeter of a floor of the building and may be connected to all of the motorized window treatments on the floor (e.g., in a daisy-chain configuration). Wiring the DC power bus in such a manner may dramatically reduce the installation labor and wiring costs of an installation, as well as decreasing the chance of a miswire.

A motorized window treatment may be configured to adjust a position of a covering material to control the amount of daylight entering a space. The motorized window treatment may include a DC power source for charging an energy storage element, such as a supercapacitor and/or rechargeable battery. The energy storage element may be configured to provide power for the operation of a motor used to adjust the position of the covering material. The energy storage element may discharge when providing power to the motor and may charge such that the current it draws from a battery is at a desired average current level that extends the lifetime of the battery.

A hembar may define a front portion and a rear portion configured to slidably engage each other. The front portion and the rear portion, when slidably engaged, may define a slot configured to receive a piece of fabric. The front portion and the rear portion may be configured to clamp the piece of fabric within the slot. The front portion and the rear portion may be configured such that a width of the slot is adjustable. The front portion may define a first attachment surface and the rear portion may define a second attachment surface. The first attachment surface may define a rib. The second attachment surface may define a groove configured to receive the rib when the front portion is slidably engaged with the rear portion such that the piece of fabric is clamped within the slot.

A control device for controlling power delivered to an electrical load includes a faceplate subassembly and a main control module. The faceplate subassembly includes a faceplate, a button, a circuit board, and a back cover. The faceplate includes a front surface and an opposed rear surface, and an opening extending therebetween with the button disposed in the opening in the faceplate. The back cover is positioned adjacent to the circuit board and defines a plurality of holes. A shaft of a post extending from the faceplate is disposed in one of the holes in the back cover and an end of the post is enlarged such that the back cover is captured between the end of the post and the rear surface of the faceplate. The main control module is configured to cause power delivered to the electrical load to be adjusted in response to depression of the button.

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.

Motorized window treatment

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 motorized window treatment for controlling the amount of daylight entering a space through a window includes a covering material, a drive shaft, 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 to minimize motor usage and conserve battery life. 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. 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.

A sensor assembly comprises a housing having a major face and a side edge. The side edge is formed of a material that is capable of conducting light. A photosensitive element is positioned within the housing and facing the major face of the housing. A reflector is positioned within the housing. The reflector is shaped to direct light entering through the side edge onto the photosensitive element.
