Definitions

  • the present invention relates to a slatted blind cornprising a flexible pull member to which a bottom crossmember of the blind is suspended and which is wound around a drum rotatable to either hand to raise and lower the blind.
  • blinds of this kind have metal or plastics slats which are mounted parallel with one another on flexible ladders, for instance, of textile material, the ladders being suspended on a tilting mechanism for varying slat orientation.
  • the pull members at least two of which are normally provided, are metal or plastics cables or tapes.
  • the pull members of the known blinds slacken if an obstacle prevents the :blind from being lowered, possibly with the result that the pull members may he accidentally twisted so that the blind becomes unserviceable.
  • FIG. 5 is a partial elevation view of a blind-raising mechanism, to a larger scale than that shown in FIG. 1;
  • the ring 35 is so screwed on the sleeve 32 as to considerably compress the conical washers 33, 36 forming a friction brake between the stationary wall 34 and the rotatable sleeve 32.
  • the spring 30 forms a one-way coupling between the sleeves 19 and 32 and is wound in a sense such that there is a rigid connection between the sleeves 32 and 19 when the sleeve 19 rotates in the direction indicated by the arrow B, corresponding to a lowering of the blind, whereas the coupling slips when the sleeve 19 rotates to the hand indicated by the arrow A, corresponding to the blind being raised.
  • the brake therefore operates only during the descent of the blind and is automatically cut out of operation during the raising of the blind.
