Abstract
A covering for an architectural opening has a dual cord operating system. The covering may include a head rail, blind panels depending from the head rail, and an operating system. The operating system may include a housing connected to the head rail, a first drive assembly rotatably mounted within the housing and operable to move the blind panels between an extended configuration and a retracted configuration, and a second drive assembly rotatably mounted within the housing and operable to move the blind panels between a closed configuration and an open configuration.
Claims16
A drive assembly for an architectural covering, the drive assembly comprising:
- a first pulley;
- a second pulley operationally engaged with the first pulley;
- a first operating cord passing around the first pulley and extending at least partially in a downward direction for manual actuation;
- and
- a second operating cord passing around the second pulley and extending at least partially in a transverse, longitudinal direction along an architectural structure or feature to actuate the covering to extend or retract across the architectural structure or feature;
- wherein the first and second pulleys are coaxial and rotate about a common rotational axis that is oblique in orientation with respect to the downward direction of the first operating cord and the transverse direction of the second operating cord, and wherein the common rotational axis of the first and second pulleys is angled to and extends in same direction as the longitudinal direction of the second operating cord.
