Rail for a fabric blind and method of attaching rail to a fabric

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 B that extends generally radially and substantially parallel with respect to the second axis.

Winding mechanism

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.

Drive mechanism and head rail for a blind

A releasable end stop is provided for an assembly of carriers and spacers that can be moved longitudinally within a head rail of an architectural covering, such as a covering for an architectural opening, and particularly a vertical venetian blind, wherein the end stop permits movement of operative components of the covering to permit cleaning and servicing of the control system for the covering.

Releasable end stop

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.

Carrier and spacer assembly

A vertical blind ( ) rail having an elongate channel ( ) including a base wall ( ) extending widthwise in a first direction between first and second base edges ( ), first and second side walls ( ) extending respectively from the first and second base edges to respectively first and second side edges ( ) in a second direction generally perpendicular to said first direction, first and second inturned flanges ( ) extending inwardly in generally said first direction from the first and second side edges respectively so as to define a slot ( ) therebetween, wherein the vertical blind rail is formed by roll-forming a first elongate sheet into a cross-section partly conforming to the cross-section of an inner channel ( ) of the blind rail, roll-forming a second elongate sheet into a cross-section partly conforming to the cross-section of an outer channel ( ) of the blind rail, feeding the partly roll-formed first sheet for the inner channel into the partly roll-formed second sheet for the outer channel, and roll-forming the first and second sheets together to form the blind rail.

Blind rail

A method of forming a strip-like mounting element ( ) in situ on a side of a flexible, preferably fabric, sheet ( ) comprising the steps of proving a thermoplastic, preferably a hot-melt adhesive ( ), in a heated state in a longitudinally-extending undercut groove ( ) of a longitudinally-elongate receiving member ( ), and pressing the side of the sheet ( ) against the thermoplastic in a longitudinally-extending opening ( ) in the groove ( ). Whereby one side of the thermoplastic adheres to the sheet and an opposite side of the thermoplastic is removably positioned in the groove of the receiving member.

Method for mounting a fabric

An end cap and mounting support combination comprising an end cap ( ) disengagably engagable with a support bracket ( ) and one of the end cap and the support bracket being provided with: a laterally open slot ( ) for accommodating an axially extending protuberance ( ) on the other of the end cap and the support bracket; and closing means to prevent the protuberance from escaping from the laterally open slot; wherein the closing means comprises a rotatable locking collar ( ) surrounding the laterally open slot and having a circumferential entrance opening ( ) which can be aligned with the laterally open slot by rotation of the locking collar relative to the laterally open slot from a closed position to an open position, thereby selectively providing access to the laterally open slot through the circumferential entrance opening.
