摘要： The window shade pocket system may comprise a pocket having an inside surface, a first wall and a second wall, wherein a roller shade is mounted within the pocket; and a first bracket removably affixed to the inside surface of the first wall of the pocket, wherein the first bracket retains a light source. The light source may include at least one of a light bulb, light bar, light strip, LED lighting or reflective device. The light source may be LED lighting that is modular or provides different colors over the window shade fabric. The light source may include a lens. The light source may be at least one of removeable from the first bracket or rotatable within the first bracket. The light source may be at least one of between the window shade and the window, or between the room and the window shade.

摘要： A base structure and associated method for converting the base structure into an operable vane on a shade for an architectural opening. The base structure includes a back sheet and a front sheet attached together in engagement regions spaced along the length of the back sheet and front sheet. The front sheet is separated into front strip sections having a free end. Operating elements are positioned along the back sheet and situated so as to move relative thereto. The operating elements are attached adjacent to a free end of the front strip. Movement of the operating elements actuates the free end of the front strip to move from a closed position to an open position as desired by the user.

摘要： A clutch cover for a roller blind clutch. The clutch cover comprises a clutch barrel portion mounted upon and extending outwardly from a first side of a backing plate, a cover ring and one or more indexing locators to fix the position of the cover ring relative to the backing plate when the cover ring is releasably secured about the backing plate. The cover ring includes a chain guide and is releasably securable about the backing plate such that the cover ring encompasses the backing plate. The indexing locators prevent relative rotational movement between the cover ring and the backing plate when the cover ring is releasably secured about the backing plate. The indexing locators permit the chain guide to be positioned at a plurality of angles relative to the backing plate.

摘要： A roller shade including a flexible sheet member having opposite parallel first and second edges, and a roller shaft rotatable in each of two opposite directions of rotation. The flexible sheet member being attached along its first edge to the roller shaft, while the second edge of the flexible sheet member is freely depending from the roller shaft. The roller shade further comprises a counterbalancing device for balancing a portion of the flexible sheet member that is unwound from the roller shaft. This counterbalancing device has means for storing a variable torque that is complementary to a variable weight of the portion of flexible sheet member that is depending from the roller shaft. The means for storing variable torque includes a helically wound tension spring operatively interposed between a stationary central rod and the roller shaft.

摘要： A cordless retractable shade including an operating system for the shade that varies a biasing force of a spring to counterbalance the shade. The bottom rail of a retractable shade can be raised or lowered, and due to the operating system remains in any selected position of the covering between fully extended and fully retracted, without the use of operating cords. The system includes a method of negating and reversing the spring bias effect at a strategic position whereby the flexible vanes of the shade can be adjusted between open and closed.

摘要： An apparatus supports two blind rollers from a headrail in one of at least eight configurations. Each blind roller has a first end coupled to a first blind control mechanism and a second end coupled to a second blind control mechanism. The apparatus includes a bracket having a top flange for coupling the bracket to an end of the headrail. An inner face of the bracket has an upper engagement projection configured to secure at least one of: the first blind control mechanism for the upper blind roller in one of two mechanism orientations, and the second blind control mechanism for the upper blind roller. The inner face also has at least two lower engagement recesses, each configured to receive a lower engagement connector, the projection configured to secure at least one of the first blind control mechanism and the second blind control mechanism for the lower blind roller.
