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 motorized window covering system is presented having a rotatable drive element having a guide structure and a plurality of idler attachment elements and at least one drive element positioned over the rotatable drive element. A motor is connected to the rotatable drive element and controls operation of the window covering. An external battery tube assembly is connected by a conduit to the rotatable drive element and is configured to provide power to the motor. The external battery tube assembly includes a switch and controls operation of the motorized window covering. When pulled or lifted the external battery tube assembly initiates movement, stops movement or reverses movement of the motor. In this way, the system provides a unique way of controlling operation of a motorized window covering.

A retractable covering for an architectural opening includes a headrail in which a control system is mounted and a fabric suspended from the headrail. The fabric is mounted to be moved laterally between a rolled up retracted position and an extended position across the architectural opening. At least one roller about which the fabric can be wrapped is mounted at an end of the headrail for rotation about a vertical axis, and the system includes a flexible control element that is substantially horizontally disposed for moving the covering between extended and retracted positions.

Provided is an extendable rail, comprising a main rail and an auxiliary rail arranged in parallel with the main rail, the main rail is shifted in longitudinal direction relative to the auxiliary rail, wherein the main rail is configured with a driving wheel and a first reverse wheel; the auxiliary rail is configured with a second reverse wheel, a first guiding wheel and a second guiding wheel arranged inside; a belt loop with fixed length wraps around the driving wheel, the first reverse wheel, the first guiding wheel, the second reverse wheel, the second guiding wheel, and the driving wheel in turn. The total length of the extendable rail can be adjusted according to the practical needs of consumers by adjusting the length of the overlapped area of the main rail and the auxiliary rail, which provides easy adjustment, high universal applicability and operation performance without size customization.

An electric guide rail type conveying system comprises a driving motor, a guide rail, a main transmission case, an auxiliary transmission case, a conveying member, and a moving trolley. Both ends of the conveying member are elastically deformably wound on the first rotating member and the second rotating member of a main transmission case body in two opposite winding direction. Before installation, the conveying member is basically wound on the first rotating member and the second rotating member. When a relative outer portion of the conveying member wound on the first rotating member is separated from the rotating member, a first elastic resilience opposite to one of the two opposite winding direction is generated; with the increase of a portion, separated from the first rotating member, of the conveying member, the first elastic resilience will increase; otherwise, the first elastic resilience will decrease.

The present invention discloses a double-layer day-night curtain system and a control method thereof; the system comprises an upper rail, a transmission mechanism inside the upper rail, two curtain assemblies connected to the transmission mechanism, a drive mechanism connected to the upper rail to drive the transmission mechanism, and the two curtain assemblies are disposed in parallel; the control method thereof comprises step A1, select the controller according to the curtain assembly: remote controller X for left-right type curtain assembly, and match it with the controller, and proceed to the next step; select remote controller Y for up-down type curtain assembly, and match it with the controller, and skip to step A3; step A2, the controller automatically switches to the control method for controlling the left-right type curtain assembly when matched; step A3, the controller automatically switches to the control method for controlling the up-down type curtain assembly when matched.

A foldable rail for an electric opening-closing curtain is provided which comprises a first rail provided with opposed first end and second end; the first end is connected to a primary transmission box; a first joint is sleeved on the second end; a second rail provided with opposed third end and fourth end; the third end is connected to a secondary transmission box; a second joint is sleeved on the fourth end; a connection piece connected to the first joint and the second joint that can rotate relative to the connection piece; a transmission component, one end of which connected to the primary transmission box and the other end]to the secondary transmission box both in a winding way; the transmission component runs through the first rail, the first joint, the second joint and the second rail in sequence along direction from the primary transmission box to the secondary transmission box.

System for moving objects (201,203) by a driving cable (115). The system comprises two cable spools (105,107) enabled to wind and unwind the cable both sides (115a,b). A remote cable pulley (113) is arranged for guiding, at a remote location (X), the cable. The cable spools are arranged to exert, by means of constant torque springs (117,119) a cable pretension force in a direction (T) contrary to the unwinding direction (U) of the spools. Electric driving means (108) are provided to be coupled either to the one or to the other cable spool, thus causing the cable to move from the one to the other cable spool or reversely, in order to move said one or more objects connected to the cable, or to be disengaged from both cable spools in order to enable manual operation of said one or more objects connected to the cable.

The present invention discloses a flexible and force-variable curtain fabric retractable device, including a hollow metal rod for wrapping a curtain fabric and a fixing mounting member mounted on both left and right ends of the hollow metal rod, wherein one end of the hollow metal rod is inlaid and installed with a flexible force-variable elastic structure, and the other end of the hollow metal rod is inlaid and installed with a driven structure, both ends of the hollow metal rod are rotatably connected with a fixing mounting member through a flexible force-variable elastic structure and a driven structure respectively.
