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.

In one aspect, an elongate mounting structure is elongated along a longitudinal direction and includes an elongate member having an elongate mounting member and a headrail member above the elongate mounting member. A longitudinal end of the elongate mounting member receives an extension mechanism to mount an architectural covering between two opposing mounting surfaces and the headrail member receives a drive assembly for operating a covering. The elongate mounting structure further includes an overhang part protecting from the elongate main member in a lateral direction, with the overhang part comprising an attaching section for attaching said covering to the overhang part such that the covering can extend substantially vertically in front of the elongate main member.

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 housing may also be configured to support a lift assistance subsystem at a second end of the housing. The lift assistance subsystem is configured to provide variable lift assistance to the motor drive unit. The shade system may also comprise a battery holder for holding the one or more batteries. For example, the housing may comprise an internal compartment for housing the battery holder and the lift assistance subsystem. In addition, the shade system may comprise a gear assembly configured to mechanically couple the roller tube to the lift assistance subsystem.

A free hanging safety bead chain tension device includes a clutch, a bead chain for controlling ascending/descending of a roller shade, a tension rod and more than one restriction seats. The bead chain is connected with the tension rod and the restriction seats are disposed on the rod body of the tension rod. Each restriction seat has one or more restriction tunnels for locating the bead chain adjacent to the tension rod. When pulling the bead chain to control the ascending/descending of the roller shade, the bead chain is positioned by the tension rod and the restriction seats. Accordingly, not only the bead chain can be still smoothly pulled, but also the bead chain is prevented from being pulled out by a space sufficient to twist around a neck. Therefore, a child is prevented from pulling the bead chain to twist the bead chain around the child's neck so that a safety effect is achieved.

A brake arrangement, for a retractable screen arrangement in which the a screen roller applies a retraction force to the screen and brake arrangement, includes a brake arrangement, for providing a braking force between the brake arrangement and a track which guides the brake arrangement, to resist retraction. The brake arrangement provides a brake member with a friction surface for contacting the bearing surface; a brake member support for supporting the brake member; and a forcing arrangement for forcing the friction surface against the bearing surface. The forcing arrangement includes a biasing arrangement for biasing the friction surface onto the bearing surface, and a force-increasing arrangement for increasing the force with which the friction surface engages the bearing surface. The force increasing arrangement converts a frictional force between the friction surface and the track into additional contact pressure force of the friction surface onto the guide track.
