The limit switch uses a rolling sprocket mounted on an offset pivot point mounted in a housing in combination with inserts into individual links of the chain. The sprocket engages the chain using spring tension on the pivot point and rolls along the chain as the chain moves with the teeth of the sprocket inserting into the chain link spaces. An insert is attached in a chain link and positioned such that when the curtain reaches the desired terminal position, the inserts are at the point where the sprocket contact the insert. The insert blocks the cog of the sprocket which pushes the sprocket away from the chain and inwardly into the interior of the housing. Inside the housing the limit switch that is activatedeither by contact or other means. The activation of the kill switch stops the motor and thus the movement of the curtains.

The present invention provides a shade assembly which comprises a shade fabric and a plurality of battens arranged vertically with respect to one another, each batten aligned horizontally along the fabric and forming a pleat therewith. A plurality of spacers are also provided which are coupled to and positioned adjacently to one of the plurality of battens in a direction perpendicular to a plane of the shade fabric. The plurality of spacers maintains the plurality of battens in a substantially vertical arrangement when the shade fabric is drawn into an open position.

A retractable covering such as a door or window blind or shade has a top rail, a bottom rail, a covering material extending between the top rail and the bottom rail, at least two lift cords extending downwardly from the head rail to the bottom rail for supporting the bottom rail, a covering operating system for enabling retraction and deployment of the covering, and an adjuster connected to at least two of the lift cords. The adjuster is preferably mounted in the bottom rail. The retractable covering also comprises an individual cord tensioner for allowing at least one of the lift cords to be individually tensioned. The individual cord tensioner operates independently of the adjuster. A method of adjusting the orientation and drop height of the bottom rail of the retractable covering is also provided.

The present disclosure belongs to the technical field of indoor devices, and particularly relates to a resistance regulating device for a rope-free curtain. The resistance regulating device is applied to a lifting type push-pull positioning curtain, including a cavity formed in a frame body for fixing the curtain, wherein a side surface of the cavity is provided with a transverse rope hole, a bottom surface thereof is provided with a vertical rope hole, a rope body passes through the transverse rope hole and the vertical rope hole in sequence and is connected to the curtain and the other end of the rope body is connected to a retrieval device; and a retarding unit rotatably arranged in the cavity and configured to increase resistance suffered by the rope body during vertical movement; and the cavity is further internally provided with a stop rod configured to resist the retarding unit.

A curtain assembly includes a curtain fabric, a upper supporting shaft, a lower supporting shaft, and a connecting cord. The connecting cord sequentially extends from a third supporting end portion along a corresponding side edge portion of the curtain fabric and repetitively pass through a first coupling hole of the upper supporting shaft to form a handle loop. The connecting cord passing through the first coupling hole further extends along a top edge portion of the curtain fabric and pass through a second coupling hole of the upper supporting shaft. The connecting cord passing through the second coupling hole further extends along a corresponding side edge portion of the curtain fabric to affixed on the lower supporting shaft. The curtain assembly is selectively operated between a shading position and a retracted position.

A privacy screen system for inhibiting an extraneous observer from viewing a display on an electronic device includes an electronic device that has a display and the display may be viewed. A pair of screens is provided and each of the screens is removably coupled to the electronic device. Thus, each of the screens inhibits an extraneous observer from viewing the display.

A retractable cellular shade is illustrated in various embodiments to consist of a support structure that could assume numerous forms including cellular material, flexible sheets of material, tapes or ribbons, or flexible monofilaments or similar cords of natural or synthetic fibers with the support structure supporting a plurality of vanes or slats in various configurations and orientations. The movement of the vanes or slats is totally dependent upon movement of the support structure. The fabric so formed can be incorporated into a covering for architectural openings with the covering including a headrail with means for gathering the fabric material within the headrail.

An architectural covering is presented that can be manually moved as well as moved through motorized manipulation. The system includes a header, a bottom bar and shade material and suspension cords extending therebetween. The header has an open interior compartment which includes a spring housing, a drive shaft assembly, spool assemblies and a motor assembly. The architectural covering can be manually moved by pulling on the shade material. The shade can also me moved via motorization by actuating the motor assembly through tugging, a remote control device, a voice actuation device or through the internet. In this way a novel architectural covering is presented that is easier to use than the prior art and has a plurality of methods of operation.
