摘要:
An adjustable length holder (15,115, 215, 315, 415, 515, 615, 715) that can support a vane (3) from a carrier (13) of a vertical venetian blind assembly (1). The vane holder has a length adjustable mounting (25, 125, 225) with a first end portion (48,148, 248) connectable to the carrier (13) and a second end portion (54, 154, 254) connectable to a hook member (17) for suspending the vane (3). The holder comprises a first part (27, 127, 227) extending downwardly in relation to the first end portion (48, 148, 248) and having a first engagement portion (60, 160, 260) projecting substantially horizontally and a second part (29, 129, 229) extending upwardly in relation to the second end portion (54, 154, 254) and having a second engagement portion (61, 161, 261) projecting substantially horizontally. Tthe first and second parts are operably engaged by the first and second engagement portions in a manner to allow displacement of the parts upwardly or downwardly relative to each other, by which the second end portion (54, 154, 254) can be moved into a plurality of adjusted vertical positions relative to the first end portion (48, 148, 248). The first part (27, 27, 227) comprises at least one first arm (44, 46, 144, 146, 244) extending downwardly from the first end portion (48,148,248) and a plurality of first engagement portions (60, 62, 63, 160, 162, 163, 260, 262, 263) are on the at least one first arm. The second part (27,127, 227) comprises at least one second arm (50, 52, 150, 152, 250) extending in upwardly from the second end portion (54, 154, 254) and a plurality of second engagement portions (61, 64, 65, 161, 164, 165, 261, 263, 264) are on are the at least one second arm. In any adjusted vertical positions, more than one of the plurality of the first engagement portions are opposite, and in operative engagement with, more than one of the plurality of the second engagement portions.
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 12, 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 40 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 42 containing a liquid and an impeller 46. 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 46, or a peripheral wall surface 43 of the compartment 42 has a first surface 49B that extends generally radially and substantially parallel with respect to the second axis.
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 carrier and spacer assembly for an architectural covering (1), such as a vertical venetian blind, that comprises a plurality of elongate, vertically-extending, covering portions (3) which can be moved longitudinally between first and second positions, a longitudinally-arrayed plurality of carriers (11), each of which is connected to an upper end portion (7) of one of the covering portions (3), the plurality of carriers including a lead first carrier (11') and a second carrier (11"), adapted to be moved longitudinally by longitudinal movement of the first carrier, and a third carrier (11‴), adapted to be moved longitudinally by longitudinal movement of the second carrier, a longitudinally-extending tilt rod (18), along which the carriers (11) are slidably arranged and can be moved longitudinally, with the covering portions (3), between the first and second positions, in one of the positions, the covering portions (3) being spaced apart along the tilt rod (18), and in the other position, the covering portions (3) being adjacent to one another at a longitudinal end of the tilt rod (18), means for pulling the first carrier (11') along the tilt rod (18) between the first and second positions and means for moving the other carriers (11",11‴), with the first carrier (11'), along the tilt rod (18) between the first and second positions; the moving means including a longitudinally-arrayed plurality of longitudinally-extending spacers (13), each of which is provided between a pair of adjacent carriers (11); each spacer having a leading end portion (13A) which extends towards the first position and engages a carrier (11',11") and a trailing end portion (13B) which extends towards the second position and engages an adjacent carrier (11", 11‴); the trailing end portion (13B) of each spacer (13') and the leading end portion (13A) of the adjacent spacer (13") being longitudinally overlapped, wherein the leading end portion (13A) of each spacer contacts a carrier (11', 11") farther from the tilt rod (18) than its trailing end portion (13B) contacts an adjacent carrier (11", 11‴) when the carriers and spacers are moved longitudinally towards the first position, whereby the carriers (11) are easier to move longitudinally towards the first position.
摘要:
A releasable end stop for an assembly of carriers (11) and spacers (13) that can be moved longitudinally within a head rail (4) of an architectural covering (1), such as a vertical venetian blind, to open and close the covering; the end stop comprising a longitudinally-movable release plate (27) in the head rail (4) that is between an active end cap (6) and a trailing spacer (13B) of a most trailing carrier (11 B) and that is affixed to a trailing end (14B) of the trailing spacer (13B) of the most trailing carrier (11B) and a longitudinally-extending, flexible resilient tongue (31) that is on the active end cap (6) and is adapted to detachably hold the release plate (27) against movement of the release plate away from the active end cap (6) with longitudinal movement of the spacers (13) and carriers (11) away from the active end cap.
摘要:
A holder for suspending a hollow vertical section of an architectural covering, such as a hollow, fabric or plastic louver (3) of a vertical venetian blind (1), from a carrier (11) of a horizontally-extending head rail (5), the holder (13) comprising a vertically-extending, generally cylindrical, male part (27) having an upper portion (25), connected to the carrier (11) and a lower portion (31) and a generally inverted U-shaped, female part (29) having a horizontal top member (43) with a pair of parallel, downwardly-extending legs (45) on opposite sides and a downwardly-extending hole (47) through it; the facing surfaces of the legs (45) each having a first detent (49) adjacent the bottom of the legs. The first detents (49) extend towards each other and are adapted to be inserted through apertures (9) in opposite sides of the hollow vertical section (3) and the lower portion (31) of the male part (27) is inserted in, and force fit within, the hole (47) of the female part (29).
