Definitions

  • the invention relates to an architectural covering having a plurality of adjustable and retractable slats.
  • an architectural covering that further includes a fixed stationary rail at one end of its plurality of slats, a movable rail at an opposite end of the plurality of slats, which is movable to and from the fixed rail to create extended and retracted positions of the architectural covering.
  • raising and lowering of the movable rail is controlled by at least one continuous cord that is arranged in a closed loop with both its opposite ends attached to the movable rail.
  • Such a retractable slatted covering is known from US4687041 .
  • this window covering at least one fixed cord return guide is adapted to be stationary mounted in a plane extending through the fixed rail, the plurality of slats and the movable rail.
  • the fixed cord return guide is positioned at a location spaced from the fixed rail and beyond the movable rail to an extent determined by a maximum extension required for the covering.
  • the present invention provides an architectural covering having a plurality of adjustable and retractable slats, the architectural covering further includes: a fixed stationary rail at one end of the plurality of slats; a movable rail at an opposite end of the plurality of slats and movable to and from the fixed rail to create extended and retracted positions of the architectural covering; at least one continuous drive cord arranged in a closed loop with both its opposite ends attached to the movable rail; at least one fixed cord return guide adapted to being stationary mounted in a plane extending through the fixed rail, the plurality of slats and the movable rail, and in a location spaced from the fixed rail and beyond the movable rail to an extent determined by a maximum extension required for the covering; at least one drive spool adapted to be selectively rotatable in opposite directions of rotation, the at least one continuous drive cord being wrapped about the at least one rotary drive spool to establish a driving engagement, the at least one drive cord extends from the at least one
  • an architectural covering 1 in the form of a slatted venetian type blind.
  • the blind 1 includes a plurality of adjustable and retractable slats 3, bordered on an upper end by fixed stationary rail 5.
  • a movable rail 7 is positioned at the lower and of the plurality of slats 3 and is parallel to the fixed rail 5.
  • First and second continuous drive cords 9, 11 are arranged at opposite lateral edges of the architectural covering 1.
  • Associated with each of the first and second drive cords 9, 11 is a respective first and second cord return guide 13, 15 which are each mounted in a stationary position remote from the fixed rail 5 and beyond the movable rail 7, to an extent determined by the maximum extension necessary for the architectural covering.
  • first and second drive spools 17, 19, Positioned at each lateral end of the headrail 5 are first and second drive spools 17, 19, each associated with a relevant one of the first and second drive cords 9, 11.
  • the first and second drive spools 17, 19 are selectively rotatable in opposite directions of rotation and the drive cords are each wrapped about their respective drive spool a sufficient number of turns to provide a frictional driving engagement between the spool and the cord.
  • First drive cord 9 being wrapped about the first drive spool 17 and one of its cord branches 9a extends to the first cord return guide 13 and then back to the movable rail 7, where it is attached at 21.
  • Another cord branch 9b of the first drive cord 9 extends downwardly from the first drive spool 17 towards the movable rail 7.
  • the other branch 9b is attached to the movable rail 7 at 23 by means of a tension spring 25.
  • a similar arrangement, albeit in mirror image is adopted for the second drive cord 11, which has branches 11a, 11b, mounting points 27, 29 and tension spring 31.
  • An adjusting mechanism for adjusting the angular position of the slats 3 is provided in the form of first and second ladder cords 33, 35 and respective first and second tilt pulleys 37, 39. Each of the first and second tilt pulleys 37, 39. Each of the first and second tilt pulleys 37, 39 is driven by a first and second drive shaft 41, 43 driven by electric motor 45.
  • the first and second tilt pulleys 37, 39 each rotatably drive the respective first and second drive spool 17, 19 through lost-motion means that will be explained herein below.
  • the drive from the tilt pulleys to the drive spools is merely represented by common drive shafts 41a and 43 a.
  • FIG 2 is a perspective detail view of the second drive spool 19 together with the second tilt pulley 39 and the relevant portion of the common drive shaft 43a.
  • the drive spool 19, schematically illustrated in Figure 1 is shown in Figure 2 to be supported in a bearing cradle 47, which is adapted to snugly fit in a headrail profile (not shown, but conventional).
  • the second ladder cord 35 has side branches 3 5 a, 35b, which are interconnected at a top end that is being engaged by the tilt pulley 39. In a conventional manner the ladder 35 is also provided with rungs 35c.
  • the common drive shaft 43a has a square cross section and is non-rotatably received in a central square opening of the tilt pulley 39.
  • FIG. 3 in isolation shows the second drive spool on the common drive shaft 43a.
  • the drive spool 19 comprises, preferably identical, drive spool halves 19a, 19b.
  • FIGS. 4 and 5 exploded views are shown from opposite directions of the arrangement of Figure 3 .
  • the square sectioned common drive shaft 43a carries a drive hub 49, which is mounted for rotation with the drive shaft 43a.
  • the drive hub 49 has a radially extending cam 51 which engages an inner ridge 53b on drive spool halve 19b (visible in Figure 5 ). Because the spool halves 19a and 19b are preferably, but not necessarily, identical the cam 51 on the drive hub 49 can engage the inner ridge 53a on spool halve 19a if the parts are inversely assembled. Accordingly the assembly of the components to obtain a drive spool 19 with internal lost motion engagement is not critical as to the orientation of the parts to be assembled and no particular attention or skill is required.
  • the cam 51 can engage the relevant inner ridge 53a or 53b on either side after almost a full revolution of the drive hub 49, before starting to rotate the drive spool 19. This will provide sufficient angular movement for the tilt pulley 39 to tilt the slats, before movement of the movable rail 7 starts to raise or lower the architectural covering.
  • Figure 6 which corresponds largely to Figure 2 , shows an alternative embodiment of drive spool in an exploded arrangement.
  • the second tilt pulley 39, the ladder cord 35, the common drive shaft 43a and the bearing cradle 47 are identical to those described in reference to Figure 2 .
  • the different form of drive spool, in Fugure 6, includes an inner part 119a and an outer part 119b.
  • the inner part 119a is non-rotatbly engageable on the common drive shaft 43 a by a square central bore 120 for rotation with the common drive shaft.
  • the inner part 119a further carries a radially projecting can 151.
  • the outer part 119b of the drive spool includes an inwardly directed ridge 153, which is adapted to be engaged on either of its opposite sides by the cam 151.
  • the engagement of the ridge 153 by the cam 151 is separated by the major part of one revolution of the inner part 119a.
  • the common drive shaft 43a will tilt the ladder cord 35 upon every change in rotative direction.
  • the cam (51 or 151) driven by the common drive shaft 43 a, can only engage the outer part 119b, the drive spool will only start raising the covering after the slats have been fully tilted.
  • Such a lost-motion is particularly desireable for slatted coverings that are raised and lowered by a drive cord that is routed through an endless loop. It effectively prevents premature raising or premature tilting during the operation of such coverings.
  • tilt drive pulleys 37 and 39 While fairly conventional tilt drive pulleys 37 and 39 have been described with reference to Figures 1 , 2 and 6 , it should be understood that also more sophisticated tilt drive units may be used.
  • One particularly suitable unit forms the subject of EP 1 213 438 ( Figures 1 to 4 ) and the disclosure of that reference is hereby included for that purpose.
  • an electric motor 45 is shown for driving the tilt drives 37, 39, this can be replaced by any suitable conventional manual drive means, such as a chain or crank drive.
