The present invention provides a cordless blind apparatus that can be conveniently operated without a cord. The cordless blind apparatus includes: a roller that is fitted on a rotary shaft; a screen that is wound or unwound on the roller; a weight that is connected to the lower end of the screen and applies torque in a first direction in which the screen is unwound from the roller by the gravity; an elastic member that applies torque in a second direction in which the screen is wound, by applying elastic force to the roller; and a friction stopper assembly that generates friction force on the roller.

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.

Example motor assemblies for architectural coverings are described herein. An example architectural covering assembly includes an architectural covering movable between an upper limit position, a lower limit position, and a transition limit position between the upper limit position and the lower limit position. The example architectural covering assembly also includes a motor, a consumer touchpoint, and an architectural covering controller. In response to detecting a first gesture at the consumer touchpoint, the architectural covering controller is to activate the motor to move the architectural covering to the transition limit position and stop, and in response to detecting a second gesture at the consumer touchpoint, different from the first gesture, the architectural covering controller is to activate the motor to move the architectural covering through the transition limit position and to the upper limit position or the lower limit position.

A covering for an architectural covering is provided. The covering may include a multiple stage spring assembly. The spring assembly may include a non-rotatable first member, a first spring including a first end portion and a second end portion, and a second spring including a first end portion and a second end portion. The first end portion of the first spring may be coupled to the first member. The first end portion of the second spring may be coupled to the second end portion of the first spring to rotate with the second end portion of the first spring.

According to some aspects, provided are curtain assemblies configured to operate in high wind environments. The curtain assembly can include first and second track guide including internal security rails. The internal securing rails moveably engage end portions of fabric stiffeners to provide stability in the curtain. In some embodiments, the securing rails include ramp portions to accommodate drift in the curtain and/or fabric stiffeners without compromising operation of the curtain.

According to some aspects, provided are curtain assemblies comprising two or more curtains selectably moveable between an open position and a closed position. Some embodiments include a track guide for at least one of the curtains having a first track and second track insert coupled to respective sides of the track guide and the curtain, wherein the curtain is moveably coupled to the first and second track inserts, and moveable along the channel of operation during transition between the open and the closed position. The curtains can be configured to define an air pocket that improved the energy efficiency of the curtain assembly (e.g., improving heat and/or noise properties). Some embodiments include a roller guide to maintain spacing between the curtains and can define a boundary of the air pocket.

A blind assembly for building openings is provided. The blind assembly is switchable from having one roller tube to more roller tubes by changing the number of end plates. The blind assembly may also include a chain guide to guide the chains from the roller tubes such that the chains do not interfere with each other.

A window for use on a structure has a first frame, a second frame and a fascia. The structure has a wall having an interior surface, an exterior surface, and an opening extending through the wall from the interior surface to the exterior surface. The opening has an upper edge, a lower edge, a first side, and a second side. The first frame contacts the interior surface of the wall and extends through the opening. The second frame is positioned below the opening and contacts the interior surface of the wall. The fascia is connected to the first frame and contacts the exterior surface of the wall.

A retractable dual screen system provides auxiliary environmental protection for garage door openings. An upper housing is mounted on an exterior of a garage door, including two rollers and is accessible for maintenance or repair by a removable cover. A first roller is a vinyl insect screening, and a second roller contains polyolefin material to provide an additional layer of insulation to help reduce heat loss and gain through the garage door. The second roller also provides a vapor barrier to help protect the garage door against high winds. A dual track system selectively allows both rollers to be independently deployed over the garage door opening.

A customizable glass wall system is disclosed. The system comprises at least two glazed, transparent panes mounted to a frame, creating an internal space less than approximately five inches thick. At least one upper roller is mounted to an upper portion of the frame, preferably on a removable headboard, and at least one lower roller is mounted to a lower portion of the frame, preferably to a removable tailboard. At least one partitioned film is attached to the upper and lower rollers. The partitioned film has partitions with varied properties and functions, ranging from thermal insulation to decoration, which can be selectively positioned behind the transparent panes by rotating the partitioned film by means of the rollers until a selected partition of film is displayed. The system can be automated based on time, weather, amount of sunlight, or user preference, and it may include window coverings or solar cells.
