Quick-Release Control System For Architectural Opening Covering

摘要

Quick-release control systems for architectural opening coverings and associated control systems and methods for rapidly deploying the coverings to extended positions. In one embodiment coupling assemblies are provided for controllably coupling and decoupling portions of lifting mechanisms in a variety of covering systems, including roller and cellular shade systems. In yet other embodiments, control systems for controlling a plurality of coverings are provided, which may be configured to remotely and simultaneously deploying each of the plurality of coverings to an extended position in response to a trigger signal.

主权项

1. A quick-release covering system for covering an architectural opening, comprising:
a head rail, a bottom rail, and a covering material extending therebetween, said bottom rail configured to move relative to said head rail between a fully retracted position and a fully extended position; a control system configured to control a position of said bottom rail to thereby controllably move said bottom rail between the fully retracted and fully extended positions, said control system including;
a lift mechanism, said lift mechanism including an elongate member extending along a first axis, and a clutch coupled to the elongate member, said clutch configured to transmit a rotational force to said elongate member to rotate said elongate member; anda quick-release mechanism including a coupling assembly, said coupling assembly configured to releasably couple said elongate member to said clutch, wherein said bottom rail is configured to move toward said fully extended position under the pull of gravity when said elongate member and clutch are decoupled by said coupling assembly.
