OPERATION, CONTROL AND SUSPENSION SYSTEM FOR A VERTICAL VANE COVERING FOR ARCHITECTURAL OPENINGS

摘要

A covering for an architectural opening includes a new system for mounting t he controls for the covering within the head rail such that suspended vertical vanes are closely positioned relative to the bottom of a head rail and disposed so as to form a continuous and integrated look with the head rail. An improved pantograph is used in the control system with one set of links of the pantograph having tapered side edges to improve stacking of the vanes adjacent to the e nd of a head rail without sacrificing strength and therefore quality of the control system. An improved operating system in the form of the combination of a tilt wand, coupler and pull cord provides a simplified system for not only moving the vanes along the length of the head rail betwe en extended and retracted positions but for also pivoting the vanes about longitudinal vertical axis between open and closed positions. An improved system for connecting suspended vanes to the control system is also provided with the system being uniquely designed for use with tubular vanes and retains the vanes in a tubular orientation. The tilt wand is connected to the tilt rod within the head rail by an inclined drive connector that enables the tilt wand to be aligned with the pull cord at the location where the pull cord drops from the head railfor manipulation by an operator. In this manner, the combined tilt wand and pull cord establish a substantially child-proof operating system fo r the covering.
