Definitions

  • a slatted roller blind consists of a large number of parallel slats parallel to each other and usually extending horizontally.
  • the lamellae are cylindrically curved around an axis extending parallel to the lamellar axis, in order to obtain sufficient kink stability.
  • the individual slats are kept at a distance to each other, wherein between adjacent slats each creates a light gap.
  • the spacers for the slats are strickleiterleiternliche structures on the rungs the slats rest. With the help of two bands running through all slats, the length of the slat blinds thus formed can be varied.
  • the light entry can also be varied by more or less tilting of the slats.
  • NL 106341 shows a sheet with a plurality of parallel adjacent bars, which are held together by connecting cords to a sheet. Each two adjacent bars are spaced apart to form a gap. The sheet is flexible about axes parallel to the bars.

  • the connecting means also allow flexibility of the sheet about axes parallel to the bars.
  • the bars are, viewed in relation to a plane defined by the sheet, in cross-section, flattened on a side facing the seize of the sheet, or have a flat rear side.
  • the novel fabric can thus be used both as a material for window blinds, awnings and the like, ie for regulating the passage of light, as well as wall or ceiling coverings, especially for influencing the room acoustics. Due to the gap between the bars, the sound absorption in the room can be influenced.
  • the connecting means may be formed by at least two at least approximately line or band-shaped connecting elements, via which the individual rods are connected to the sheet together.
  • the line-shaped connecting means may either pass through openings in the bars or they may extend over the outer peripheral surface of the bars and be connected to the outer peripheral surface.
  • connection point which are twisted together in the region of the gap.
  • connection means is the use of individual links, each connecting only two bars. Their shape depends on the type of bars involved.
  • the bars of the fabric are preferably predominantly hollow for weight reasons.
  • the rods may have a constant cross section over their length.
  • the rods may have the shape of circumferentially completely closed tubes or they may be designed as tube-like structures containing on one side a longitudinal gap passing through.
