The present disclosure relates to a roman shade curtain which can improve a curtain atmosphere and the interior of a house by folding or unfolding the curtain in a stepwise manner like a lace. The roman shade curtain can be easily folded or unfolded in a stepwise manner by adopting a combination of rods and rings as a means for corrugating the middle of the curtain, so that the roman shade curtain may have a simple structure, be easily manufactured, and have excellent durability and improve the appearance of the curtain by arranging rods, rings, and the like on the rear surface of the curtain as well as wires for curtain operation.

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 roman shade has a frame, a blind detachably mounted on the frame, a retraction device mounted on the frame, a rolling member, and two guiding members. The rolling member is retractably mounted on the retraction device and has a rolling tape. A bottom end of the rolling tape is free without being connected to the blind. The guiding members are mounted on the retraction device and are located beside two sides of the rolling member. Each guiding member has a guiding tape retractably mounted on the retraction device. A bottom end of the guiding tape surrounds a connecting rod, which is mounted on a body of the blind. The guiding tape is detachably connected to the body of the blind through the connecting rod. It is convenient to detach the body of the blind for cleaning the blind.

A stacking panel covering for an architectural opening includes a headrail and a plurality of suspended from the headrail. The panels form an overlapped stack at one end of the headrail when the stacking panel covering is opened, and cover the architectural opening when the stacking panel covering is closed. The panels are piggybacked on those adjacent thereto, so that they stack, one behind the next, when the stacking panel covering is opened, and so that each pulls the next adjacent thereto as the stacking panel covering is being closed. The panels themselves may be planar, or convexly curved in a horizontal direction and substantially straight in a vertical direction.

A modular shade includes at least one module that consists of a head rail unit, a foot rail unit, at least one intermediate rail unit, and a plurality of slat components. A top slat may be coupled to the head rail unit and the intermediate rail unit, and a bottom slat component may be coupled to the intermediate rail unit and the foot rail unit. Further, additional intermediate rail units and intermediate slat components may be added to the module to alter the shape and size of the module, and the module may be coupled to one or more additional modules to change the overall shape and size of the modular shade.

A roman shade includes a rolling assembly, two brackets, a beam, a fabric, and a roller shade; both ends of the rolling assembly are respectively supported by the two brackets and the two brackets are disposed on the beam. The beam includes a side wall connected to the fabric. The roller shade is attached to the back of the fabric. The roller shade includes a top portion secured to the rolling assembly. The rolling assembly includes a housing, a shaft, an end connector, a sealed fixing element, a spring, and a fixed part. The shaft is disposed in the housing. The housing includes an inner wall including a plurality of ribs disposed at intervals. The shaft includes a first end and a second end. The first end is rotatably disposed through the end connector and secured to one of the two brackets.

A motor driven system for raising and lowering a window covering executes motor ramp trajectory speed control. The motor ramp trajectory limits acceleration of an external motor from the idle (stationary) state to full operating speed, and limits deceleration of the motor from full operating speed back to the idle state. This function reduces stresses on a continuous cord loop drive mechanism. A control system manages solar heating effects in response to sunlight entrance conditions such as system sensor outputs, external weather forecasts, and other data sources. The system automatically opens or close the window covering to increase or decrease admitted sunlight under appropriate conditions. The input interface of the control system includes a visual display and input axis, which are aligned vertically if the window covering mechanism raises and lowers the window covering, and are aligned horizontally if the window covering mechanism laterally opens and closes the window covering.

A control device for coupling with a shaft of a window blind and controlling rotation of the shaft includes first and second ratchet seats, a spool assembly operable to rotate in unwinding and winding directions, a tubular case, an output unit coupled with the shaft, and a transmission unit operable to be shifted between a transmitting state to have a torque transmitted to the output unit, and a non-transmitting state to interrupt the torque transmission. Each ratchet seat has a surrounding groove and teeth. Balls are rollably engaged in the surrounding groove and the spool assembly for permitting rotation of the first ratchet seat with the spool assembly in the unwinding direction, and not to rotate the first ratchet seat in the winding direction.

In various aspects, a covering for an architectural structure includes a bottom rail assembly that can be efficiently and effectively assembled during manufacturing of the covering. Specifically, in one embodiment, the bottom rail is configured such that one or more operating system components of the covering can be mounted within and directly supported by the bottom rail. In addition, a separate cover may be coupled to the bottom rail during the assembly process.
