Abstract
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.
