A control system for a vertical vane covering for architectural openings

摘要

A control system (22) for a vertical vane covering for an architectural opening includes a new and improved symmetric headrail (20) having uniquely designed carriers (26) for suspending individual vanes (24) wherein the carriers (26) are designed to minimize skewing relative to a tilt rod (42) as they are moved along the headrail (20). A pantograph (44) system is utilized to interconnect the carriers (26), and is connected to the carriers (26) in alignment with the tilt rod (42) so as to minimize skewing. The carriers (26) have pockets (164) formed therein through which the traverse cord (68) extends so that the traverse cord (68), which moves the carriers (26) along the tilt rod (42), is secured to a lead carrier (26) closely adjacent to the tilt rod (42) to, again, minimize skewing. Light blocking rails (240) are also attachable to the headrail (20) to substantially bridge the gap between the headrail (20) and the top of the suspended vanes (24) to prevent light from passing therebetween. The tilt rod (42) is keyed to gears in the carriers (26) to facilitate assembly of the control system (22) with all vanes (24) properly aligned.
