7562689 - Clip for window covering cord - Owned by Shades Unlimited, Inc. (Cotati, CA)

A clip is provided which acts as a holder for a lift cord or other cord of a window covering. The clip includes a fastener through which the clip is coupled to a lower portion of the window covering, such as a bottom rail of the window covering. The clip also includes a guide path which supports a portion of the cord adjacent to the clip. The clip would typically be coupled to a lower portion of the window covering, such as a bottom rail, at a lateral edge of the bottom rail, so that the cord has a reduced amount of vertical suspension from the bottom rail and is reoriented to a new desired position extending down from the clip on the bottom rail. The guide path can be a partial or complete hole or trough through which the cord is routed.
