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.
  • an architectural covering such as a window blind or shade
  • a head rail a bottom rail
  • a covering element 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 means to limit the downward movement of the bottom rail and which also comprises an adjuster connected to at least one of the lift cords; the adjuster having: a first part, to which an end of the cord is secured; a second part engaging the bottom rail or the head rail; and means to adjust the relative position of the first and second parts.
  • 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 adjuster of the invention can be mounted in the bottom rail and be connected to the lower end of a lift cord. With such an arrangement, it is preferable that the second part of the adjuster form an end cap for the bottom rail.
  • the adjuster can be provided in the cord connector and be connected to the upper end of the lift cords.
  • 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 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 lowered 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 lowered 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 (only one of which is shown in Figure 2) then 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.
  • a similar adjuster can be provided in the cord connector 18.
  • 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.
