Definitions

  • the present invention relates to a gathering and pivoting device for slat blinds with a pull-up shaft, which one Bobbin for an elevator element of the slat blind curtain and has a turning element rotatable on the winding shaft, at which the two ends of swivel members for the slats are fixed and the one between the winding shaft and the turning element friction clutch and two end stops to limit the turning range of the turning element resp. of the slats and an intermediate one, intermediate stop actuated by the elevator element has, the impact effect when fully lowered Slat blind curtain is lifted.
  • Such a device is for example from DE-A-32 05 491 known.
  • Such a device allows the slats the slat curtain in an open, a closed Position and an intermediate position by a single Actuating process for gathering the slat curtain, which acts on the elevator axis to fix. this will by means of an arranged on the elevator axis, with this between stops connected in a frictionally engaged manner reached.
  • a locking slide is provided for the intermediate stop, which is controlled via an actuating element becomes.
  • the object of the present invention was now to such a known device for gathering and swiveling Louvre blinds to improve that they are for one Blinds with slat areas to be set differently can be used.
  • two swivel members for one two-part slat curtain provided.
  • Such slat blinds are particularly well suited for shading workstations equipped with screens.
  • the lower half of the curtain gives direct sun exposure to the workplace prevent what the slats in this area at least are partially closed, and the upper half of the curtain as much light as possible in the upper area of the workplace guide to the best possible natural To allow lighting for what the slats in this area aligned in an almost fully open position are.
  • These slat positions are according to the invention automatically created when the curtain is lowered. Leave with the slats completely lowered the slats of all curtain areas over the entire intended Swivel the swivel range with the single control element.
  • the winding shaft 2 of the slat blind is inserted, as shown in Figure 1.
  • This winding shaft 2 can, for example, have an angular shape or a round shape Have tongue and groove.
  • the cylinder body 3 can be of course also be constructed in several parts.
  • the winding shaft 2 is non-rotatably connected to the cylinder body 3, for example by a tongue and groove connection or purely form-fitting by means of an angular cross-section.
  • an actuator for example a crank or an engine (not shown)
  • the winding belt 5 is wound onto the spool 4 resp. unrolled and thus raised the slat blinds resp. lowered.
  • the mentioned actuator When lowering or opening the slat blind the mentioned actuator are the rocker disks 6 and 7 always in the corresponding direction up to the respective Stop moved.
  • the end stops for the rocker disks 6,7 are usually positioned in such a way that the slatted curtain both in completely closed and in completely open position can be brought. So when lowering the blind curtain the slats in a predetermined Position can be, it is with such devices known to provide an additional intermediate stop, which from the stop position to a rest position can be brought.
  • FIG. 1 shows the intermediate stop proposed according to the invention, formed as a slide 14 with compression spring 15, in Stop position shown.
  • the coil spring ends come here 8 'and 9' against the slide 14 to the stop.
  • Fig. A shows the upper slat area
  • Fig. b shows the lower slat area next to each other for the sake of clarity.
  • the Winding shaft rotated in the direction of the arrow as shown in Fig. 4.
  • the slide 14 as previously based on the Figures 1 and 2 explained, in the stop position.
  • the spring end 8 '' of the rocker disk 6 thus comes immediately to the as a stop serving slider 14 to rest, as in Fig. 4 a) shown.
  • the seesaw 7 is when lowering by a certain angle, here e.g. pivoted about 37 ° until the spring end 9 '' also comes to a stop on the slide 14.
  • the position of the elevator belt and the swivel elements on the slats is shown schematically in Figure 6.
  • the slat curtain is by the slats 22 in the top and the slats 23 formed in the lower area.
  • the elevator belt 5, which can be wound on the bobbin 4, performs Openings 22 ', 23' in the slats 22, 23 through to one Final slat (not shown).
  • the slats 22 des upper slat curtain area are by swivel cords 10, 11 connected to each other. Guide the swivel cords 10, 11 to the rocker disk 6. By turning the swivel disk 6 you can the slats 22 are pivoted together.
  • the slats 23 of the lower slat curtain area are also through more swivel cords 12, 13 connected and can be pivoted through the rocker disk 7. These swivel cords 12, 13 are, for example, by eyelets 24 on the Slats 22 out.
  • the swivel cords advantageously have 10.11 resp. 12.13 between the respective top Slat of the corresponding slat curtain area and the corresponding rocker 6 respectively. 7 length adjustment elements on. This allows the basic slat position in the fully installed Slat curtain can still be adjusted precisely.
  • the proposed device according to the invention is suitable especially for a slat curtain with an upper and lower area separately pivotable slats, like them used particularly advantageously for computer workstations will. It is the easiest way to do that Slat positions of both curtain areas as required only one operation and the whole Lowering or raising the slatted curtain.
