摘要： A head rail for a vertical blind, the head rail being elongate and having a drive mechanism at one end for selectively tilting and retracting slats of the vertical blind along the length of the head rail, the drive mechanism including a rotatable tilt drive for tilting slats, a rotatable retract drive for retracting and deploying slats, and a transmission for rotating the tilt drive and the retract drive by means of a single rotatable source, wherein the transmission includes a clutch for rotating the tilt drive, the clutch incorporating a lost motion mechanism whereby, after a predetermined number of rotations in the same direction, transmission by the clutch to the tilt drive is disengaged and wherein the transmission includes a control gear which is located at a position along the length of the head rail so that it can be meshed with teeth of an external drive source.

摘要： A winding mechanism for controlling the retraction and deployment of an architectural covering, such as a window blind or shade having a winding element, about which the covering, or its lift cord or tapes are wound and unwound with rotation of the winding element about a first axis of rotation, and a fluid brake for retarding the rotation of the winding element in at least one direction about the first axis. The fluid brake comprises a fluid tight compartment containing a liquid and an impeller. The compartment and the impeller are adapted for relative rotation about a second axis, which can be the same as or coaxial with the first axis. Either the compartment or the impeller is operatively connected to the winding element. In operation the liquid rotates with the rotation of the compartment or the impeller about the second axis. Rotation of the liquid relative to the impeller or to the compartment in at least a first direction about the second axis is effective to retard the rotation of the winding element in at least a second direction about the first axis. The impeller, or a peripheral wall surface of the compartment has a first surface that extends generally radially and substantially parallel with respect to the second axis.

摘要： A carrier and spacer assembly for an architectural covering, such as a vertical Venetian blind, comprising a longitudinally-arrayed plurality of carriers that are slidably arranged for longitudinal movement along a longitudinally-extending tilt rod between open and closed positions. In the open position, the carriers are spaced apart along the tilt rod, and in the closed position, the carriers are adjacent to one another at a one end of the tilt rod. A mechanism is provided for pulling a first carrier along the tilt rod between the open and closed positions. A plurality of elongated spacers are disposed between the adjacent carriers, connecting them together along the tilt rod. Each spacer includes a leading end portion which extends towards the open position and engages a carrier and a trailing end portion which extends towards the closed position and engages an adjacent carrier. The trailing end portion of each spacer is longitudinally overlapped by the leading end portion of the adjacent spacer, wherein the leading end portion of each spacer contacts a carrier laterally farther from the tilt rod than its trailing end portion contacts an adjacent carrier when the carriers and spacers are moved longitudinally towards the open position.
