Definitions

  • the present invention relates to an expandable honeycomb structure such as used for window coverings, and made of a foldable material which, in the expanded condition, defines a plurality of longitudinally extending cells, one on top of the other. In the retracted state of the structure, the adjacent cells are collapsed on each other.
  • the invention also relates to a method of manufacturing such a structure.
  • US-A-4450027 discloses a method of construction in which the foldable material is folded longitudinally and wound onto a rack in overlying layers which are adhered together to form the cells of the honeycomb structure.
  • the opposite longitudinal edges of a single length of material are progressively folded over one side of the material and adhesive is applied to the exposed longitudinal edges, whereby they adhere to the overlying layer of folded material as it is wound onto the rack.
  • honeycomb structure is to be used for window coverings or panels
  • a porous material to give a translucent effect when the honeycomb structure is in its expanded condition.
  • adhesive there is a tendency for adhesive to bleed through which can result in opposite walls of the individual cells becoming adhered together as they are wound on the rack in overlying layers.
  • Woven, knitted or non-woven fabrics and laminates can be used for this purpose but because of their inherent porous nature, the adhesive can bleed through and the product is either unusable or the cells must be carefully pulled to their expanded condition before the adhesive has fully set and this can be difficult during manufacture.
  • the material can be made less permeable in the portion or portions to which the adhesive is to be applied in a number of different ways. For example if it is a woven, knitted or non-woven fabric, then the density of the fibres can be made greater in these portions so that the interstices between the fibres is significantly less. Additionally, or alternatively, the material can be made to be thicker in these portions zone thereby rendering it less permeable to adhesive.
  • the thickness of the material is greater than twice the thickness of the cell material in the remaining part of the cell and it may be as much as four times the thickness. This may be achieved by having four layers disposed in the zone of the adhesive and the cells may be joined with the adhesive disposed centrally between the four layers of material, with two layers on either side thereof.
  • a window blind comprising a upper rail l0 and a lower rail l2 and a number of generally hexagonal cells l4 are formed from a rear face l6 and a front face l8 which are pre-creased for example as taught by US-A-4450027, and are secured together by adhesive using connecting strips 20.
  • Figure 5 shows a further construction in which instead of having simply front and rear sheets, alternate sheets l6, l8 zig-zag in interleaved relation. Thickened portions 28 are provided at the centre and further thickened portions 30 at the ends of these sheets at the zone when the adhesive is to be applied.
  • Figure 3 illustrates a suitable sheet for this purpose which, as can be seen, is made of a woven or knitted fabric and the weave or knit at 28 or 30 are far more dense than the remainder of the fabric.
  • This fabric may or may not actually be thicker in this more dense portion. It will normally be more practical to produce a relatively wide fabric and to cut this up to form elongate strips bordered by the thickened portions 30. It will be seen that these are approximately half the width of the thickened portions 28 so that the fabric can be manufactured with a series of more dense zones similar to the zones 28, and alternate ones of these can be cut centrally to provide the thickened portions 28.
  • the cell material has been shown as originally flat and formed in to the cell formation during the manufacture of the honeycomb structure, it is comtemplated that the cells could be pre-formed, e.g. of tubular material. In this case the zones where adhesive is applied to join the cells will be formed of less permeable material than the remainder.
