Definitions

  • the present invention relates to a covering assembly particularly for windows, doors and other architectural openings.
  • window covering assembly which includes a first and second generally parallel spaced apart vertically extending sheer fabrics having a plurality of spaced generally parallel transversely extending vanes fixedly secured to the first and second sheer fabrics to extend therebetween.
  • the sheer fabrics are often constructed of a translucent or transparent material and may be in the form of woven or knitted fabrics or non-woven fabrics or indeed may simply be sheets of plastics material.
  • the vanes are usually opaque or semi-opaque and by adjusting the relative positions of the sheer fabrics, the vanes can be caused to tilt relative to the sheer fabrics rather in the manner of the slats of a horizontal or vertical blind.
  • the vanes extend horizontally in such assemblies and the sheer fabrics are supported on a tilt roll which can also be used as a wind up roll.
  • vertical venetian blinds in which the individual vanes extend vertically; such assemblies have a head rail for opening and closing the assembly and for tilting the vanes when the assembly is in the closed position covering the opening.
  • a window blind comprising in combination, a front light transmitting sheet having a plurality of parallel alternately forwardly and rearwardly directed pleats formed therein, a rear light transmitting sheet spaced apart from said front sheet in substantially parallel relation therewith and having a plurality of parallel alternately forwardly and rearwardly directed pleats formed therein, each forwardly directly pleat on one of said sheets in a neutral position of said window blind being in alignment with a rearwardly directed pleat on the other of said sheets, and a plurality of substantially parallel relatively non-light transmitting vanes having opposite side edges, one side edge of each vane being attached to said front sheet and the other side edge being attached to said rear sheet, whereby when one of said sheets is moved with respect to the other of said sheets from said neutral position in one direction of movement transverse to said vanes, said vanes are caused to lie perpendicular to said sheets whereby to allow passage of light through the blind material, and when said sheets are moved relative to each other from said neutral position in the opposite direction of movement
  • FIG. 1 there is illustrated one form of window blind assembly indicated by the reference numeral 510.
  • This assembly 510 is associated with a headrail 512 provided with an elongate tilt roll member 514 means (not shown) being provided to rotate this roll about its generally horizontal axis.
  • the material 510 includes a front sheer fabric 516 provided with a plurality of spaced parallel, horizontal forward pleats 518 and rearward pleats 520.
  • the material 510 also includes a rear elongate sheer fabric 522 formed with forward pleats 524 and rearward pleats 526 similar to the pleats 518,520 of the front elongate sheer fabric 516.
  • vanes 528 interconnect the front and rear sheer fabrics 516,522.
  • the vanes 528 in Figure 2 extend between a rear, interior, face of a rearwardly extending pleat 520 of the front sheer fabric 516 diagonally upwardly to where it is connected to the forward interior face of a forwardly extending pleat 524 of the rear sheer fabric 522.
  • front and rear sheer fabrics 516,522 are connected to a bottom rail 530 adjacent their lower ends and are connected to the elongate tilt roll 514 at their upper ends.
  • a spacer member 532 is provided below the headrail and is connected to the front and rear sheer fabrics adjacent further pleats 518,526 thereof. This spacer 532 is not essential but provides a better configuration for the upper parts of the pleated blind material.
  • FIG. 3 shows a slightly modified structure in which like parts have been indicated by like reference numerals.
  • the vanes are here indicated by the reference numeral 534 and are connected slightly differently.
  • the lower parts of the vanes 534 are connected to the rear, interior, face of a forwardly extending pleat 518 of the front sheer fabric 516 and the vanes are again inclined diagonally upwardly and connected to the front, interior, face of a forwardly extending pleat 524 of the rear sheer fabric 522.
  • the vanes 534 are not planar as in Figure 3 but are reversed curved as shown at 536 and 538.
  • such a structure is, in some ways, rather similar to a venetian blind with the vanes 528,534. It will be appreciated that if the tilt roll 514, in either structure, is rotated in a clockwise sense, as seen in Figure 2 or Figure 3, the vanes 528,534, will overlie one another because they are in an overlapping mode and will thus, effectively, block the passage of light. If, however, the tilt roll 514 are tilted in a counter-clockwise sense, then the vanes 528,534, can be moved to a position in which they extend substantially horizontally, while remaining parallel to one another, so that there can be a passage of light therebetween.
  • the sheer fabrics 516,522 need to be formed of a translucent or transparent material, such as paper, or woven fabric, or non-woven fabric, or indeed they can be made of a plastics material.
  • the vanes 528,534 can be made of any suitable material. However, they are preferably formed of an opaque or semi-opaque material.
  • the vanes are connected in a suitable manner to the respective pleats 518,520,524,526 as appropriate. While it is contemplated that this could be done by a heat technique, such as by welding, they are preferably adhered by means of a third material such as stitching or stapling, but according to a preferred arrangement they are connected by being adhered, preferably using a hot melt adhesive, which melts at a temperature significantly below the melt temperature of the sheer fabric. It would be appreciated that the sheer fabric needs to have the pleats set in it and this can be done by a heat setting process which should again be conducted at a temperature in excess of the temperature of melting of the hot melt adhesive.
  • FIG 4 a further rather different structure is illustrated.
  • This structure has the pleats of the sheer fabrics extending generally vertically.
  • the structure of Figure 4 employs a headrail 540 in which are mounted a plurality of sliding carriers 542 which are preferably provided with wheels (not shown) for running along guide tracks 544 formed in the headrail. Movement of the carriers 542 can be effected in any suitable manner but as shown a cord system 546 is provided.
  • the assembly of carriers in the headrail may be generally similar to that disclosed in US Patent 3996988 in the name Dwight or in US Patent 4267875, in the name Koks.
  • a tilt rod 547 is provided and this may be rotated by a pulley 548 with a bead chain 550.
  • the tilt rod 547 is associated with a worm and worm wheel, as in Koks US Patent 4267875, and the worm wheel in each carrier is connected to a separate hanger 552.
  • Figure 5 there is illustrated a form of window covering suitable for covering a skylight in a horizontal or inclined roof.
  • the assembly includes a flexible window covering indicated by the general reference numeral 410 this including the first sheer fabric 412, a second sheer fabric 414 and a plurality of transversely extending vanes 416 extending therebetween, the vanes being generally parallel to one another.
  • This window covering 410 can be made in a number of different ways which do not form part of the present invention.
  • the sheer fabrics 412,414 are made of a translucent or transparent material such as paper, a woven fabric or non-woven fabric or indeed they can be made of a plastics material.
  • the vanes 416 can be made of any suitable material. However, they are preferably formed of a opaque or semi-opaque material.
  • the sheer fabrics 412,414 are connected to circumferentially spaced apart fixing means 420,422 on a wind up roll 424 which is mounted with its longitudinal axis extending generally horizontally to one side of the frame of a skylight.
  • cord reels 426,428 Associated with the roll 424, at each end thereof, are cord reels 426,428 and a control pulley 430 at the end adjacent the reel 426.
  • Rotation of the wind up roll 424 can be effected by operation of a cord, for example a bead cord 432 wrapped around the control pulley 430.
  • a motor drive could be provided. This rotation is also imparted to the cord reels 426,428.
  • tension cords 34,36 which also pass around fixed pulleys 438,440 and are connected to opposite ends of an end rail 442 having, in its interior, a tension spring 444 to the ends of which are attached the ends of the tension cords 434,436.
  • end rail 442 is attached to the second sheer fabric 414 only.
  • Two parallel tracks 443 are provided, one on each side of the covering, the tracks extending generally perpendicular to the axes of the wind up roll 424 and the end rail 442, the tracks for example being of channel or L-cross-section.
  • a runner 445 is mounted and is slidable longitudinally in the adjacent rack 443 and serves to guide and support the rail. If desired further runners (not shown) could be provided on some of the vanes 416, these also sliding in the tracks. It is also contemplated that the tracks 443 and runners 445 could be omitted, particularly on smaller installations.
