A covering for an architectural opening is provided. The covering may include a roller rotatable about a longitudinal axis, a shade associated with the roller, and an operating system operably associated with the roller. The operating system may include a base, a drive mechanism, a transmission, an actuator arm, and an engagement arm. The drive mechanism may be associated with the base to provide an input torque. The transmission may be associated with the drive mechanism to selectively transmit the input torque to the roller. The actuator arm may be associated with the base to indirectly set a rotation direction of the roller. The engagement arm may be associated with the base and engageable with the transmission.

In one aspect, a cordless covering may include a roller and a shade panel configured to be wound around and unwound from the roller to move the shade panel between an extended position and a retracted position. The shade panel may include a front panel, a back panel, and a plurality of vanes extending between the front and back panels. The covering may also include a roller shaft extending through the roller and a tilt adjustment mechanism coupled to the roller shaft. The tilt adjustment mechanism may be configured to rotate the roller shaft to adjust a tilt angle of the vanes between an opened position and a closed position.

A covering for an architectural covering is provided. The covering may include a rotatable outer roller, a rotatable inner roller, a first shade secured to the outer roller, and a second shade secured to the inner roller. The outer roller may define an elongated slot extending along a length of the outer roller and opening to an interior of the outer roller. The inner roller may be received within the outer roller and may define a central longitudinal axis. The first shade may be retractable onto and extendable from the outer roller. The second shade may extend through the elongated slot and may be retractable onto and extendable from the inner roller. The elongated slot may be substantially horizontally aligned with the central longitudinal axis of the inner roller when the first shade is in a fully extended position.

A motorized sheer shading system may move a sheer shade material between an open position, a closed position, and a view position. The shading system may move the sheer shade material from the open position to the closed position at a first average rotational speed, and from the closed position to the view position at a second average rotational speed. The shading system may automatically determine a control limit that corresponds to the closed position of the sheer shade material after control limits have been set for the open position and the view position. The shading system may cause the sheer shade material to stop moving once it reaches the closed position if the raise button of a remote control is still depressed, and may cause the sheer shade material to stop moving once it reaches the closed position if the lower button of the remote control is still depressed.

A panel unit includes an interconnected first and second pair of juxtaposed panels, a spacer joining together opposing inner faces of the pairs of panels about a periphery of the interconnected pair to define common air space therebetween, first and second blind assemblies positioned in the air space between the first and second pair of panels respectively, a first drive shaft coupled to a first set of louvers of the first blind assembly and a second drive shaft coupled to a second set of louvers of the second blind assembly, an actuator connected to the first drive shaft, and an interface structure rotationally fixing together opposing ends the first and second drive shafts, wherein the first drive shaft is responsive to actuation of the actuator to axially rotate and thereby cause simultaneous rotation of the first and second sets of louvers between the open and closed positions thereof.

An actuating system for a window shade includes a fixed support shaft, a rotary drum pivotally connected with the support shaft, the rotary drum being rotatable for winding or unwinding a shading structure, and a limiting mechanism disposed inside the rotary drum and including a threaded portion provided on the support shaft, a stop portion, a limiting part, and a follower engaged with the threaded portion, the stop portion and the limiting part being respectively disposed adjacent to a first and a second end of the threaded portion, and the follower being rotationally coupled to and slidable relative to the rotary drum. The rotary drum is rotatable in a first direction to drive the follower to slide toward a first position for engagement with the limiting part, and in an opposite second direction to drive the follower to slide toward a second position for engagement with the stop portion.

A system and method for automatically determining at least one lower limit of a horizontal sheers style roller shade. The roller shade comprising a roller tube, a shade material attached to the roller tube and comprising a first vertical layer interconnected to a second vertical layer via a plurality of horizontal vanes, a motor adapted to rotate the roller tube, a current sensing circuit adapted to detect current levels of the motor, and a controller adapted to control the motor and comprising at least one memory. The controller determines at least one lower limit by driving the motor in a first direction, receiving current levels from the current sensing circuit, observing current level profile of the received current levels, detecting a point of change in the current level profile, and using the point of change to set at least one of a lower tilt closed limit and a lower tilt open limit. During normal operation, the controller drives the motor between the upper limit and the lower tilt closed limit to raise or lower the shade material and between the lower tilt closed limit and the lower tilt open limit to open or close the vanes.

A motorized sheer shading system may move a sheer shade material between an open position, a closed position, and a view position. The shading system may move the sheer shade material from the open position to the closed position at a first average rotational speed, and from the closed position to the view position at a second average rotational speed. The shading system may automatically determine a control limit that corresponds to the closed position of the sheer shade material after control limits have been set for the open position and the view position. The shading system may cause the sheer shade material to stop moving once it reaches the closed position if the raise button of a remote control is still depressed, and may cause the sheer shade material to stop moving once it reaches the closed position if the lower button of the remote control is still depressed.
