An opening and closing device for curtains and a system based on the same, mounted on a curtain track, comprises a main engine and a roller mechanism, The main engine comprises a shell with a cavity, a driving wheel mounted in the cavity and partially exposed the shell, a motor arranged in the cavity and controlling the driving wheel to rotate, a controller lied in the cavity and controlling the motor to start and stop, and a signal transceiver module coupled electrically with the controller and receiving starting and stopping signals of the motor; the driving wheel is used for driving the curtains to move along the curtain track; a roller mechanism is mounted on the shell, an end, far away from the shell, of the roller mechanism is hung on the curtain track and presses the driving wheel closely on the curtain track.

An electric curtain track structure includes a guiding track assembly, a first actuator, a transmission assembly and a decorative assembly. The guiding track assembly includes a guiding track main body having first and second bending sections opposite from each other. The first actuator is installed on the first bending section. The transmission assembly includes a transmission cable and first hooks. The transmission cable is inserted into the guiding track main body and driven by the first actuator to move along the guiding track main body. The decorative assembly includes a decorative panel and heads. The decorative panel is attached onto an outer side of the guiding track main body, and two ends of the decorative panel protruded out of the guiding track man body for the decorative heads to correspondingly install on an outer side of the first and second bending sections. Consequently, the overall appearance thereof is improved.

A hanging material (i.e. privacy curtain) support system may include a coupling device, a ceiling mount assembly, and hanging material support tubing. The coupling device may include a removable guide section. The removable guide section may facilitate proper alignment of the coupling device to the hanging material support tubing. If the coupling device is not properly aligned and fixed with the support tubing, the support tubing may not be provided in a level state for allowing support attachment members (i.e.—C-shaped hooks) to flow/move freely across the support tubing. When the support tubing is not secured/fixed in a level state, the attachment members may not move/slide properly across the support tubing which would degrade the operation of the entire system (i.e.—moving a hanging material—i.e. privacy curtain—from open to closed states and vice-versa).

A suspension system for curtain rods a wall plate for securing to a wall and a car slidably received therein for adjusting the position thereof with respect to the wall plate. A curtain rod comprises a first and second channels, one channel including a hook portion for engaging a cooperating hook portion of a clip mounted directly or indirectly to a wall or ceiling.

A track hanger (100) includes a hook (103) and an extension (104), a base member (102), and a key (403). The key is detachable from the hook, and the base member is detachable from the extension. The key can include a first major surface (401) and a second major surface (402). The first major surface can define one or more barbs (404) that facilitate one-way insertion of the key into a track (106).

A sliding screen system for a sliding screen includes a linear slide bar and at least one sliding member. The linear slide bar has a slide surface coated with a lacquer including a resin. The lacquer is in turn at least partly coated with a lipophilic composition coating. The lipophilic composition coating provides a slide layer on the slide bar with low friction. The sliding system is arranged to support a sliding screen, such as a sliding door or a sliding curtain, connected to the sliding member to allow for linear movement of the sliding screen along the longitudinal axis of the linear slide bar.
