Benefits of technology
"The present invention relates to window curtains that can be opened and closed using a cord or chain mechanism. The invention provides a window curtain assembly that includes a headrail, a winding mechanism, and a pair of panels that can be opened and closed by moving the inner edges upwardly and away from each other with a single pull mechanism. The invention also includes a pull mechanism that engages the clutch, allowing for easy operation of the curtains. The window curtain assembly can be used on any sized window and is convenient for use with narrow windows. The technical effects of the invention include improved ease of operation, flexibility, and aesthetic appeal."
Problems solved by technology
When closed, the panels may substantially block the window opening.
The installation of appropriately sized curtain rods alone is often difficult, requiring the proper fixed placement of curtain rod holders with respect to one another and the window.
Furthermore, the hanging of the curtain panels necessarily requires assembling the panels to the rod.
Problems not only arise in the installation of the curtain rods and assembly of the curtains to the rods, but also in the selection of the various elements, i.e. matching complementary curtain panels and curtain rods to provide an aesthetically pleasing appearance.
This is cumbersome compared to the many other window covering options, which provide a single cord or chain for opening and closing such assemblies.
However, these curtains do not have the same aesthetic appeal as curtains in which the top portion of the curtain remains relatively fixed in position with respect to the curtain rod.
However, none of these solutions provide for a window curtain assembly that can be easily assembled and operated by the end user.

Description
BACKGROUND OF THE INVENTION [0001] Window coverings are utilized for shading light or blocking the view through a window opening, or for otherwise providing an aesthetic appearance to a window. Some well-known types of window coverings include Venetian blinds, Roman blinds, Cellular shades, and curtains. Each of these types of window coverings are designed to provide various aesthetic qualities and variable amounts of window opening coverage ranging from complete coverage, partial coverage, to providing no coverage at all. [0002] A standard store purchased window covering assembly, such as a Venetian blind assembly, is a self-contained unit for mounting adjacent a window. A typical Venetian blind assembly consists of a headrail, a lift mechanism, and a tilt mechanism and a plurality of horizontally extending slats suspended from the headrail by a ladder cord. Operation of a cords or chains coupled to the lift mechanism causes the plurality of slats to move towards or away from the h...
