Wheel carriage assemblies and related fabric deployment systems and methods are disclosed. A wheel carriage assembly comprising at least one wheel with ball bearings on the interior of each wheel, and a pivot point that allows for position independence, is configured with a hembar coupled to a piece of fabric to allow a surface of varying shape to be covered. The system provides the ability to cover both traditional window shapes as well as surfaces of irregular shape or inclined orientation, and reduces and evens the amount of wear on certain components to extend system life.

Embodiments are provided of a curtain carrier forming a part of a curtain carrier assembly configured to support a curtain. The curtain carrier assembly includes an elongate track with a slot. The slot extends lengthwise along an underside of the track. A curtain carrier is slidably coupled to the track. The curtain carrier includes a spool that is slidable lengthwise along the slot. The curtain carrier also includes a stem that is pivotably coupled to the spool. In specific embodiments, at least a portion of the stem protrudes below the spool. In specific embodiments, the stem defines a hook opening sized to receive a curtain hook at a location spaced apart from the spool. The curtain carrier assembly further includes a curtain hook configured to support a portion of a sliding curtain. The curtain hook is coupled to the stem such that the curtain hook passes through the hook opening.

A window curtain driving assembly is revealed. A pulley driving assembly is pivotally connected to a main body. Pulleys disposed on the pulley driving assembly slid in a curtain track. Thereby the window curtain driving assembly rotates along curves of the window track so that it can also be applied to the curved window track. An auxiliary pulley set is mounted and fixed on a top of the main body. The pulley mount is oriented toward a given direction by the second latch bar on one side of the pulley driving assembly being mounted in the auxiliary pulley set. Thus the window curtain driving assembly can also be applied to a straight curtain track for extension or retraction of a curtain.

Disclosed is an end cap or connector for a wheel system, the end cap or connector has a cylindrical portion for engagement with one of an extension or a quick release system, the cylindrical portion further including a catch for attachment to the extension; and a cap, extending from said cylindrical portion, said cap having a connector for attaching to a wheel carriage or another extension. Also disclosed is a method which includes the end cap and inserting the end cap into an extension such as a hollow tube or rod; and releasably attaching the end cap to a wheel system.

The present application belongs to the field of spring roller shutters, and particularly relates to a spring roller shutter with adjustable function, which comprises a spring assembly in a drum, an adjusting assembly and a limiting assembly, wherein one end of the drum includes a concentric adjusting cylinder, the adjusting cylinder is connected with an output end of the spring assembly, one end of the adjusting cylinder away from the drum includes a fixed shell, the fixed shell includes a cavity with an opening facing the adjusting cylinder, the one end of the adjusting cylinder slides in the fixed shell, and the adjusting assembly and the limiting assembly are in the fixed shell, thereby achieving the benefit of adjusting the maximum withdrawal height of the curtain.

A drapery hanging apparatus, method and system including a plurality of carriers, each carrier having a support portion and a pendant for carrying draperies. The carriers are retained by a flexible strip of indefinite length so that the carriers can be fed into a hanger track in a single step.

The present application provides a roller bearing system comprising one or more bearings having a plurality of substantially hemispherical members. Each member includes an interior. A sleeve is disposed within each hemispherical member interior and configured to accept a shaft that passes through each hemispherical member, such that the hemispherical member turns about the shaft. Each also includes at least one stem coupled to the shaft. The stem is configured to provide a point of attachment to a particular bearing.
