Definitions

  • the present invention relates to a roman blinds according to the preamble of claim 1.
  • a roman blinds of this type is known in the prior art from AU-B-410 797.
  • the slats In the subsequent generation of blinds, which is in use today, the slats assume an inclined or horizontal so-called working position when the slat curtain is being lowered and raised. This often results in the disadvantage that the slats do not have sufficient mutual overlap, which causes disturbing, strip-like reflections on screens of computer systems stationed in the darkened room and in some cases dazzles the operating personnel.
  • the elimination of these faults requires a further swiveling of the slats in an inclined position, which is steeper than the working position, but this means that the whole room still darkened further and switching on the electric lighting becomes necessary. This is undesirable on the one hand because of the additional energy costs and on the other hand because of the associated additional heating of the room, which can have an unfavorable effect on the performance of the people working in the room.
  • the object of the present invention is therefore to eliminate the disadvantages mentioned, that is to say to create a store of the type mentioned at the beginning, in the lamella curtain of which the louvre is lowered in the working position, the slats have a sufficient overlap in such a way that there are no disturbing effects for the users of the room Glare and reflections on work equipment occur and without the slatted curtain undesirably darkening the room.
  • an inclination of the slats is selected for the working position of the slat curtain, in which, if necessary, after a slight swiveling of the slats, the mutual overlap is so great that no direct light falls into the interior of the room and there is an optimum at the top Light is reflected into the interior of the room.
  • the window opening 1 of a room 2 is darkened by the slat curtain 3 of a slat blind.
  • the slats 4 are not closed. You are in an intermediate position between the open and the closed position. The inclination of the slats 4 with respect to the horizontal increases from top to bottom.
  • the diffuse outside light (dotted lines) enters the room 2 in a straight line or on a broken path between the slats 4.
  • the sun's rays (dashed lines) are reflected by the slats 4 and directed into space 2 in the upper area of the slat curtain 3 after a single deflection.
  • the light inlet in the upper part of the slatted curtain 3 is thus much larger than in the lower.
  • Through the upper part of the slat curtain 3 almost as much light enters the room 2 as in a conventional Roman blind with open slats, whereas in the lower part the light passage is almost as small as in a conventional store with closed sl
  • the slat blind has an elevator shaft 5 with two elevator belt drums 6 and each assigned a rocker 7. One each of the elevator belt drums 6 and the rockers 7 are visible. From each elevator belt drum 6 leads vertically an elevator belt 8 to an end rail 9 where the elevator belt end is attached. From each rocker 7 lead two rocker strands 10, 11 down, on which the slats 4 and the end rail 9 are attached with their longitudinal edges.
  • the elevator belt 8 and the luffing strands 10, 11 can also be accommodated in the side guides of the store and connected there with corresponding slat end pieces.
  • the slats 4 of the slat curtain 3 assume a position between the open and the closed position.
  • the distances X, Y of the outer and inner longitudinal slat edges of adjacent slats 3 are constant. It is essential, however, that the distances X between the inner longitudinal slats are smaller than the distances Y between the outer ones.
  • the uppermost lamella 4 is essentially horizontal, whereas the end rails 9 are inclined at an angle of approximately 60 ° to the horizontal. For a person inside the darkened room 2, this results in the fact that he perceives the slats 4 of the slatted curtain 3 approximately at the same angle ⁇ , which means that the appearance of the slatted curtain is much more regular than in a known store.
  • All slats also have a mutual overlap ü, which eliminates any glare.
  • ü In the open position of the slat curtain 3, in which the levels of the slats 4 converge towards the space 2 (dash-dotted lines in FIG. 2), an essentially equally large view appears between all the slats 4.
  • a swivel position for the slats 4 can be set, in which the overlap ü between the two slats 4 is zero in the horizontal, or in which the inner longitudinal slat edge of the lower slat is at the same height as the outer slat longitudinal edge of the upper slat.
  • the height of this pair of slats should be set so high that at least the workstations and tools are below this pair of slats, so that annoying reflections for people working in the room are eliminated.
  • FIG. 3 differs from that according to FIGS. 1 and 2 in that the width of the slats increases from top to bottom, the limit case being shown in which the luffing strands run parallel.
  • embodiments are also conceivable for special requirements in which the slat width decreases from top to bottom.
