Definitions

  • This invention relates to an architectural covering, particularly a covering for an architectural opening, such as a window blind or shade.
  • Conventional blinds and shades for windows have included a head rail, a bottom rail, one or more window covering elements extending between the head rail and the bottom rail, at least two lift cords extending from the head rail and supporting the bottom rail, and a mechanism to limit the downward movement or drop of the bottom rail.
  • the drop height of the shades has usually been limited by a cord connector, engaging the cord outlet at the bottom of the head rail upon full drop of the bottom rail.
  • pleated and roman shades have also been provided with an additional cord to limit drop.
  • the full drop has usually been limited by the full extension of the ladder cords.
  • US 5,613,540 upon which the precharacterising portion of appended claim 1 is based describes a cord shroud used in cooperation with a window shade assembly and the like of the type having a bottom rail and a head rail, with a cord lock attached either internal or external to the headrail.
  • the window blind assembly further has at least two lift cords, each of which are connected at one end to the bottomrail, pass through the headrail and cord lock, and have an opposite end that is accessible to an operator.
  • the cord shroud is fashioned of an elongated, flexible, flexible type ribbon or a ladder type having a first end connected to the headrail and a second end that is accessible to the operator.
  • the cord shroud further has a plurality of apertures disposed along the length of the ribbon, through which the lift cords pass.
  • the ribbon has a length sufficient to fit over substantially all of that portion of the lift cords, which is exposed when the window is open.
  • the apertures may be holes provided through the ribbon or loops or rings attached to the ribbon. The ends of the lift cords accessible to the operator and the end of the ribbon accessible to the operator are connected, preferably by a handle.
  • US 5,082,043 describes a device for raising and lowering a modular aircraft window having an inner pane, outer pane, frame assembly securing the inner and outer pane, collapsible shade with a fixed and movable end, the device comprising a block and tackle having a movable pulley and more than one fixed pulley, the movable pulley and fixed pulleys connected by a cable fixed at one end and attached at second end to the moving end of the collapsible shade. Moving the movable pulley effects a movement, through the cable, through the moving end of the collapsible shade, and creates a mechanical advantage multiplying the distance moved by the lever. Guide cables are attached by way of adjusters in order to vary their tension.
  • EP 0 192 867 A1 describes a venetian blind comprising a head rail, a lift and tilt mechanism, a non-tilting bottom rail, a plurality of parallel tiltable slats mounted on ladder means extending between said tilt mechanism and said bottom rail, lift means being connected to the lift mechanism by a connecting element mounted on said bottom rail and connected to the lift means.
  • the connecting element includes a body portion mounted on said bottom rail, and a winding pin rotatable on said body portion and upon which said flexible lift means can be wound.
  • the connecting elements are on top of the bottom rail.
  • US 4,739,815 describes a balloon curtain mountable on a curtain rod.
  • the curtain also has a pull cord mechanism for vertically raising and lowering the bottom of the fabric body, and a holding sleeve for selectively holding the pull cords and the bottom of the fabric body in a desired position.
  • a sleeve has an adjustable position on the pull cord and abuts an eyelet in the fabric body to restrict movement of the fabric body.
  • a pleated shade which has:
  • the adjuster of this invention regardless of whether one accurately positions the knot originally in the lift cord of a shade or blind for a particular window height, one can subsequently adjust the position of the knot, so that the bottom rail has a full drop which is correct for the particular window. This is particularly important where two or more lift cords are knotted together and the position of their knot must be adjusted to provide the correct drop for the bottom rail.
  • the means to adjust the relative position of the first and second parts preferably comprises a screw connector between the first and second parts.
  • the pleated blind 1, shown in Figure 1 includes a conventional, longitudinally-extending head rail 10 and bottom rail 12 and a pleated window covering material 13 extending between the head and bottom rails, all of which are supported by three conventional lift cords 14.
  • Conventional brackets 15 are provided for mounting the head rail 10 on a wall, adjacent to a window (not shown).
  • the lift cords 14 pass over conventional guide means in the head rail 10 and then out of the bottom of the head rail through a cord lock 16.
  • the three lift cords 14 are connected by a conventional connector 18, from which a tassel 19 depends. This allows one to raise and lower the blind 1 by pulling downwardly on the tassel 19 to raise and lower the connection of the lift cords 14 to the bottom rail 12.
  • the connector 18 also serves to limit the drop height of the blind 1 by limiting the downward movement of the bottom rail 12.
  • the connector 18 engages the cord lock 16 at the limit of the drop height, whereby the connector 18 cannot go upwardly any further and, as a result, the bottom rail cannot go downwardly any further.
  • the bottom ends of the three cords 14 are knotted together in a conventional manner (not shown) after each cord has been passed through one of the three openings 20 in the top surface 21 of the bottom rail 12.
  • the bottom of the bottom rail 12 is of channel section and is provided with laterally opposite, i.e., front and rear, flanges 22 that extend longitudinally and laterally away from each other and with laterally opposite ribs 23 that extend longitudinally and laterally towards each other, above the flanges 22.
  • the ribs 23 act as longitudinally-extending guide rails for a first part 26 of an adjuster 27 of this invention as described below.
  • the top of the bottom rail 12 is provided with laterally opposite flanges 24 that extend longitudinally and laterally towards each other and serve to hold a second part 28 of the adjuster 27 on the end of the bottom rail 12.
  • a pair of laterally opposite prongs 29, which extend longitudinally from the second adjuster part 28, can be inserted and frictionally held between the flanges 24 and the top surface 21 of the bottom rail 12.
  • the second adjuster part 28 forms an end cap for the bottom rail 12, thereby securely engaging the bottom rail.
  • a longitudinally-elongate adjuster screw 30 Passing longitudinally through the second adjuster part 28 is a longitudinally-elongate adjuster screw 30 having a head 32 outside the end of the bottom rail 12 and a screw portion 33 within the bottom rail.
  • the screw portion 33 of the adjuster screw 30 passes longitudinally through an aperture 35 in a lowered central portion 34 of the first adjuster part 26.
  • the screw portion 33 of the adjuster screw 30 is self-tapping and forms a female thread on the walls of the aperture 35 of the first adjuster part 26.
  • first adjuster part 26 Rotation of the screw head 32 of the adjuster screw 30, with a conventional screwdriver, will cause the first adjuster part 26 to move longitudinally to the left or right, depending on the direction of rotation of the adjuster screw, towards or away form the second adjuster part 28.
  • longitudinally-extending grooves 36 are provided on laterally opposite sides of the lower portion 34 of the first adjuster part, and the ribs 23 of the bottom rail 12 can ride within the grooves 36 when the first adjuster part is moved longitudinally. If the first adjuster part 26 is molded from a plastic material or rubber, it will have a self-locking effect on the adjuster screw 30, thereby preventing unwanted longitudinal movement of the first adjuster part.
  • the lower central portion 34 of the first adjuster part 26 also has, on laterally opposite sides, two longitudinally-extending slots or elongate recesses 38, through each of which all the lift cords 14 pass in a longitudinal direction.
  • Each lift cord 14 passes through both of the slots 38 and along the side of the first adjuster part 26 closest to the second adjuster part 28, and the lift cord ends 40 are then knotted together on the other side of the first adjuster part 26, remote from the second adjuster part 28.
  • the resulting knot 42, formed by the ends 40 of the lift cords 14 is preferably held by the lift cords against this other side of the first adjuster part 26, remote from the second adjuster part 28, by the weight of the bottom rail 12 suspended from the lift cords 14 as shown in Figure 2 .
  • each lift cord 14 passes from the first adjuster part 26, upwardly through one of the openings 20 in the top wall 21 of the bottom rail 12 and then through the window covering material 13 to the head rail 10.
  • an adjuster 27 can be provided at each end of the bottom rail 12, thereby allowing the length of each individual lift cord above the bottom rail to be adjusted, so that the bottom rail 12 is perfectly level.
