Definitions

  • This invention relates to a holder for a hollow vertical section of an architectural covering, such as a tubular flexible material for covering an architectural opening, like a window or door.
  • This invention particularly relates to a holder for vertically arranged, hollow fabric louvers of a vertical venetian blind.
  • Vertical venetian blinds have generally been provided with a longitudinally-and horizontally-extending head rail, in which there have been several carriers that can be moved along the length of the head rail.
  • Each carrier has typically supported a vertically-extending louver in such a manner that the consumer could move the blind's louvers along the length of the head rail and also could rotate the louvers about their vertical axes.
  • carriers have each included a drive hub of a gear wheel driven by a worm gear, and the drive hub has supported a depending louver holder that has been adapted to support securely the top portions of a louver while the carrier has been moving and turning the holder and the louver. See US 4 267 875.
  • louver holders have held upper marginal portions of louvers: between their pairs of downwardly-extending pinching fingers (DE-Y 85 23 104, DE-A1 27 15 018 and US 4 869 309); and also on hooks that are provided on their downwardly-extending fingers and that extend through apertures in the upper marginal portions of the louvers (US 4 335 775).
  • louver holders have been unsatisfactory for use with hollow vertical louvers as described in US 5 797 442. This is because such holders have tended to squeeze together the upper marginal portions of hollow vertical louvers and, for this reason, have not maintained the tubular shape of the hollow louvers over their entire height. For this reason, the use of a hanger plate, adhesively bonded to one side of the interior of such a hollow vane has been proposed in US 5 797 442, but this has not been an entirely satisfactory solution.
  • a holder for suspending a hollow vertical section of an architectural covering, such as a hollow, fabric or plastic louver of a vertical venetian blind, from a carrier of a horizontally-extending head rail; the holder comprising:
  • the top member of the female part is generally rectangular and generally planar, and it is especially advantageous that the hole in the top member is rectangular.
  • the lower portion of the male part has:
  • the hole in the top member of the female part has:
  • each first detent has a generally cylindrical configuration with: i) its axis being normal to the leg, to which it is attached; a smooth outer surface; and iii) its outer diameter being less than, advantageously slightly less than, the diameter of one of the apertures, whereby the opposite sides of the hollow vertical section can slide easily apart on the pair of first detents after the first detents have been inserted in the apertures.
  • the hollow vertical section of the architectural covering is a deformable, generally tubular vane, especially a vane having three-dimensional and torsional stability along its length, particularly a vane made of a fabric having diagonal dimensional stability.
  • the apertures in the hollow vertical section are in opposite sides of an upper marginal portion of the hollow vertical section.
  • a head rail for an architectural covering such as a vertical blind, and an architectural covering are provided, comprising the holder, just described.
  • FIG 1 shows a vertical blind 1 having a plurality of hollow vertically-extending louvers 3 suspended from its longitudinally- and horizontally-extending head rail 5.
  • the louvers 3, are deformable, generally tubular, plastic or fabric vanes, preferably vanes such as are disclosed in US 5 797 442.
  • each louver 3 preferably has three-dimensional and torsional stability along its length and is preferably made of a fabric having diagonal dimensional stability.
  • each louver 3 is securely suspended vertically from one of a plurality of conventional carriers, generally 11, within the head rail 5, by means of a vertically-extending two-part holder, generally 13, of this invention.
  • the holder 13 is attached to the carrier 11 and to the apertures 9 of the louver 3 as shown in Figures 2-5.
  • the head rail 5, shown in Figure 1 can be any conventional head rail for a vertical blind, such as the head rail generally described in US patent 4 267 875.
  • the head rail 5 provides controlled longitudinal movement of the carriers 11 and the hollow vertical louvers 3 along the length of the head rail and controlled rotation of the louvers 3 about their vertical axes.
  • One longitudinal side of the head rail is provided with a conventional pull cord 15 that is connected in a conventional manner to the carriers 11 for moving them longitudinally along the length of the head rail 5.
  • the one longitudinal side of the head rail 5 is also provided with a conventional bead chain 17 for rotating a conventional, longitudinally-extending drive shaft (not shown) of the head rail which can rotate a conventional worm gear and its worm (not shown) within each carrier 11 so as to rotate the holders 13 and the louvers 3.
  • each carrier 11 in the head rail 5 carries a pair of rollers 19 on opposite lateral sides of its housing 21, so that the carriers can roll on longitudinally-extending tracks (not shown) on laterally opposite sides of the interior of the head rail 5, along its length, in response to movement of the pull cord 15.
  • the housing 21 of each carrier 11 has a pair of openings 23 on its longitudinally opposite sides, through which the drive shaft (not shown) of the head rail 5 passes to drivingly engage the worm gear (not shown) within the housing 21, so that rotation of the drive shaft causes rotation of the worm gear and thereby rotation of a conventional drive gear (not shown) within the housing.
  • a lower portion of the drive gear includes a hollow vertically-extending hub (not shown), into which an upper portion 25 of a vertically-extending, generally cylindrical, male part, generally 27, of the two-part holder 13 of this invention can be inserted, so that the carrier 11 supports the holder 13.
  • the upper portion 25 of the male part 27 is a conventional upper part of a vane holder for a vertical blind as described, for example in US 4 335 775.
  • the holder 13 has a generally inverted U-shaped, female part, generally 29, into which a vertically-extending, lower portion 31 of the male part 27 can be inserted to hold securely a louver 3.
  • the lower portion 31 of the male part 27 has a radially-extending shoulder 33 with a lower surface that extends circumferentially and horizontally around the top of the lower portion 31.
  • a pair of parallel planar vertical guide surfaces 35 are below the shoulder 33, on circumferentially opposite sides of the lower portion 31 of the male part 27.
  • ramp surfaces 39 which curve inwardly of the lower male part portion as the ramp surfaces extend downwardly from between the upper surfaces of the first detents 37 towards the bottom of the lower male part portion 31. Near their bottom, the ramp surfaces 39 become parallel vertical surfaces 41.
  • the female part 29 of the holder 13 has a generally rectangular, horizontal, generally planar, top member 43 and a pair of parallel, downwardly-extending legs 45 on opposite sides of the top member.
  • the top member 43 has a downwardly-extending, preferably rectangular, hole 47 through it.
  • the hole 47 has a width (measured between the legs 45) that is no less than, and preferably is greater than, the diameter (measured parallel to the guide surfaces 35) of the radially outer surface of the lower portion 31 of the male part 27, below the lower surface of the shoulder 33.
  • the hole 47 also has a length that is about the same as, or slightly less than, the radial distance (measured transverse to the guide surfaces 35) between the radially outer surfaces of the first detents 37 on the male part.
  • the vertical thickness of the top member 43, about its hole 47, is no more than, and is preferably approximately the same as, the vertical spacing between the lower surface of the shoulder 33 and the upper surfaces of the detents 37.
  • each second detent 49 has a generally cylindrical configuration, with: i) its axis normal to the leg 45, to which it is attached; ii) a smooth outer surface; and iii) its outer diameter less than, preferably only slightly less than, the diameter of one of the apertures 9.
  • the opposite sides of the upper marginal portion 7 of each louver 3 can slide easily apart on the pair of second detents 49 of the female part 29 of each holder 13 after the second detents have been inserted in the apertures.
  • the distance between the facing free ends of the second detents 49 is sufficient to allow opposite sides of the upper marginal portion 7 of a louver 3, with its pair of apertures 9, to be pressed together, so that such opposite sides of the louver 3 can then be inserted between the free ends of the second detents until such free ends can pass freely through the apertures 9 into the hollow interior of the louver and such opposite sides of the louver 3 can then be released and allowed to return resiliently to their inherent, generally tubular configuration.
  • the distance between the free ends of the second detents 49 is preferably no more than about the distance between the parallel vertical surfaces 41 at the bottom of the ramp surfaces 39 of the male part 27. This allows the parallel vertical surfaces to pass downwardly between the free ends of the second detents 49 when the lower portion 31 of the male part 27 is urged downwardly into, and thereby force fit within, the hole 47 in the top member 43 of the female part 29. As a result, the parallel vertical surfaces 41 will fill the space between the free ends of the second detents 49 to prevent one or both of the apertures 9 of a louver 3 from becoming accidentally disengaged from the second detents of the assembled holder 13.
  • the carriers 11 and holders 13 can be made of conventional (e.g., plastic) materials. However, it is essential that the plastic of the male part 27 and/or female part 29 of the holder 13 be sufficiently flexible and resilient, so that the lower portion 31 of the male part can be force fit within the hole 47 in the top member 43 of the female part to hold securely the top member between the first detents 37 and the shoulder 33 of the male part and thereby keep the two-part holder 13 together when, in use, it holds a depending louver 3.
  • plastic of the male part 27 and/or female part 29 of the holder 13 be sufficiently flexible and resilient, so that the lower portion 31 of the male part can be force fit within the hole 47 in the top member 43 of the female part to hold securely the top member between the first detents 37 and the shoulder 33 of the male part and thereby keep the two-part holder 13 together when, in use, it holds a depending louver 3.
  • the holder 13 can be used to hold securely a hollow louver 3 from a carrier 11 of the head rail 5 in a relatively simple manner.
  • the upper marginal portion 7 of the louver 3 can be squeezed together (against the inherent resilience of the louver), so that its apertures 9 are brought together.
  • the free ends of the second detents 49 of the female part 29 can then be inserted through the apertures 9.
  • the upper marginal portion 7 of the louver 3 can be released, so that it elastically becomes generally tubular again and its apertures 9 can slide away from each other on the second detents 49.
  • the lower portion 31 of the male part 27 can then be pushed downwardly into the hole 47 of the top member 43 of the female part 29 to force fit the two parts together in the assembled holder 13.
  • the parallel vertical surfaces 41 of the male part 27 contact the free ends of the second detents 49 of the female part 29 and thereby prevent the apertures 9 of the louver 3 from slipping off the second detents of the female part.
