Definitions

  • the present invention relates to venetian blinds, and in particular to a tilt shaft and tilt roll support mountable in a channel section venetian blind headrail.
  • GB-A-2120716 discloses a venetian blind headrail of channel cross-section and having a web portion, two flanges, the flanges each having a beaded rim at their free edges.
  • a number of supports are mounted and serve to carry a common tilt shaft and an equal number of tilt rolls on which the ladders which support the slat are mounted to enable the slats to be tilted, and also they include an opening in the base, a peripheral surface of the opening serving, in use, for guiding a flexible lift element downwardly out of the venetian blind headrail.
  • a tilt shaft and tilt roll support mountable in a channel section venetian blind headrail of a given size, said headrail including a web portion and two flanges, said flanges each having a beaded rim at their free edges, said headrail housing at least two tilt rolls, a tilt shaft drivingly engaging said tilt rolls and first and second flexible lift elements extending along and downwardly from said headrail, said support comprising a base shaped to be positioned adjacent the web portion of the venetian blind headrail, bearing portions on said base for receiving and supporting a tilt roll and/or tilt shaft, an opening in the base, a peripheral surface of the opening serving, in use, for guiding a first flexible lift element downwardly out of the venetian blind headrail, characterised in that said support further comprises at least one upstanding arm having a free end sufficiently close to or engageable against one of said rims, to allow a flexible lift element to be forced past and at least one upstanding member extending upwardly from the base forwardly or rearward
  • the upstanding member is used to separate the second and any further lift cords from the first lift cord which passes downwardly through the opening of the first support within the headrail.
  • the upstanding member there serves to separate the second lift cord from the third or further lift cords and so on.
  • the upper portion of the upstanding arm is positioned closely adjacent the confronting one of the beaded rims one can thread the lift cord therebetween even when the tilt roll support and its tilt roll are mounted in the headrail.
  • the at least one upstanding arm is chamfered and may also be resilient to facilitate insertion of the cord between the chamfered upper end and an adjacent rim of the venetian blind headrail.
  • the upstanding member may be formed in the base immediately adjacent the opening and the confronting bearing portion may be laterally spaced from its associated upstanding member, the lower surface of the confronting bearing portion being located below the upper surface of the upstanding portion, the lateral spacing then left is sufficient to allow the lift cord to be manipulated into place below the lower surface.
  • the upstanding member can have substantially the same height as the upstanding arm.
  • the confronting bearing portions are each spaced laterally inwardly of said upstanding members.
  • Said at least one upstanding member may have a distal end close to or engageable against the tilt shaft and/or tilt roll when in use.
  • the support In order to retain the support in place, it preferably comprises engaging means which engage under the other of the beaded rims of a headrail.
  • the engaging means may comprise further resilient arms extending upwardly at longitudinally spaced locations from the base portion, and another portion protruding through an opening in the headrail web portion.
  • a headrail 10 including a web 12 and two side flanges 14, each having an inturned beaded rim 16 at their upper free edges.
  • the headrail web 12 has an opening 18 and at this location is positioned a support 20 according to the invention.
  • This support includes a base 22 which has a portion protruding through the opening 18, the base including two laterally spaced apart bearing portions 24 having open-topped cylindrical recesses for accommodating a tilt roll (not shown) for rotation about an axis 26 ( Figure 1).
  • Forming part of each portion 24 is an integral upstanding arm 28 which extends up to be closely adjacent to the front one of said inturned beaded rims 16.
  • the top surface of the upstanding arm 28 is chamfered at 30.
  • upstanding members 32 Mounted within or forming part of the base 22 are two laterally spaced apart upstanding members 32 which extend forwardly (or rearwardly if desired), to a level above the height of a peripheral surface 34 serving to define a guide for a flexible lift element, such as a lift cord 36, which passes laterally of the support, that is longitudinally of the headrail, and then downwardly through the base and thus through the opening 18.
  • the peripheral surface 24 and the upstanding members 32 conveniently form part of a separate insert mounted within the base 22. It will be seen that the upper surface of the upstanding members 32 has spaced therefrom a confronting lower portion 38 of the bearing part 24.
  • the uppermost tip of the upstanding member 32 extends above the lower surface of the confronting portion 38 and is laterally spaced therefrom, as can be seen from Figure 1. The spacing is sufficient to allow the cord 36 to be threaded under the portion 38 and over the top of the upstanding member 32.
  • a further lift cord 37 is shown passing to the right and extending to a subsequent support (not shown) similar to the support 20.
  • the upstanding member 32 and the confronting portion 38 prevent this cord 37 from becoming entangled with the cord 36.
  • the upstanding arm and confronting rim 16, 28 will prevent the further cord 37 from accidentally escaping from the headrail. This is particularly helpful while handling the headrail during assembly.
  • bearing portions 24 are provided with upstanding holding members 25 which engage under the rear beaded rim 16 to hold the support 20 in place.
  • a support 120 is provided with a base 122 which has integrally formed therewith two bearing parts 124 for mounting for rotation a tilt roll 121 which can be driven by a tilt shaft 123. Rearwardly and upwardly extending elements 125 engage under the rear beaded rim 116.
  • a central portion 129 of the base 122 extends for a distance between the front and rear flanges 114. Formed in this central portion is a guide surface 134 leading down to an opening (which cannot readily be seen in the drawings) leading into an opening in the web portion 112 of the channel section headrail.
  • An upstanding arm 128 is formed integrally with the bearing parts 124 and has a curved or chamfered upper surface 130 which is closely spaced from the front rim 116.
  • the upstanding members 132 Projecting upwardly from the base 122 are again two laterally spaced upstanding members 132, whereby in this embodiment the confronting bearing parts 124 are spaced inwardly of the upstanding members 132.
  • the upstanding members 132 each have a preferably resilient distal end projecting well above a confronting surface 138 on the adjacent bearing part 124 and ending close to or against the tilt shaft 123, so as provide a restricted passage for a lift cord.
  • FIG. 4 The method of assembly is shown in Figure 4 in which a portion 136 A of a lift cord 136 is shown being fed around the chamfered surface 130 of the upstanding arm 128. It will be seen that the cord is being fed behind the upstanding member 132, the upper surface of which is above the confronting surface 138 of the bearing portion 124. The part 136A of the cord 136 is then fed round chamfered surface 130, between upstanding member 132 and tilt shaft 123 and underneath confronting surface 138 to take up the position illustrated in Figure 4. Each subsequent cord 137 can then pass freely to the right, as viewed in Figure 4, of the upstanding member 132 so that there will be no fear of it becoming entangled with the first lift cord 136. As is apparent from Figures 4 and 5 the above cord threading operations can be performed with the tilt shaft and tilt rolls in mounted position.
