Definitions

  • the present invention relates to a slat blind according to the preamble of independent claim 1.
  • slat blind includes both roman blinds and all-metal blinds. These serve to secure the windows and shade rooms.
  • the slats are laterally provided with pins that protrude through vertical slots in the side guide rails and engage in a link plate.
  • the link plates are rotatably connected to one another at their two ends by support members, so that the position of the link plates can be changed by changing the position of the pairs of support members. This can usually have the effect that the slats can be pivoted from the normal vertical position into a horizontal position in the completely lowered position of the store. These two positions are automatically assumed by the movement of the store.
  • the slats When lowering, the slats remain in the closed or vertical position and can be brought into the open or horizontal position by means of a small counter-movement, as when pulling up the store.
  • the respective room is either completely shaded or completely dark or the solar radiation cannot be shaded to the desired extent.
  • DE-A-37 22 604 also describes a turning device for Roman blinds. With this arrangement, it is desirable that the slats in the lowered position are not necessarily brought into the closed position, but remain in a semi-open position. Special operating cords are also provided here for turning or for pre-setting the slat position.
  • a Roman blind in which the slats can assume three positions, namely an open, a partially open and a closed position. It is envisaged that the semi-open position when lowering can only be maintained as long as the store is not fully lowered. When the store is completely lowered, the slats automatically assume the closed position.
  • the object of the invention is to provide a Roman blind, in which an additional factory-set position of the slats is possible according to the need for shading without additional adjustment ropes or cords or the like, and in which this additional position over the entire stroke length, also in completely lowered position is maintained.
  • Fig. 1 and 2 show a Roman blind in frontal view and in sectional view. According to the frontal view, a number of slats 2 are guided on both sides in guide rails 1 in the usual way.
  • the two ends of the two-armed lever 5 hold a chain, formed from articulated support members 17, 18, of which the respective upper support member 17 has bearing openings 11 on both sides for connection to the respective lower support member 18, which has a stop 13 for determining the stretched state the chain.
  • a drawstring 14 on the left and right of the slats 2 is fastened at its lower free end to a slide support 12 and this slide support 12 pushes the two slides 7, 8 right and left of the slats downwards or upwards.
  • a locking lever 9 is attached to the carriage 7, 8 itself, with which the store located in the lower end position can be secured. As far as this or a modification of this store is well known in specialist circles, it does not need to be described further here.
  • the reel shaft 29 ends in a hexagonal shaft section 30.
  • the band reel 33 which is installed in a housing 31 with a cover 32.
  • the tension band 14 (FIGS. 5 to 7) is wound on this band reel 33.
  • a rocker 36 (FIG. 4) is rotatably mounted on the hexagonal shaft section 30 and comprises a rocker arm 36a and a control arm 36b, which two parts 36a and 36b are arranged diametrically.
  • the rocker arm 36a is provided with an adjustment pocket 36c which protrudes outwards through a slot in the housing and can thus be adjusted from outside the housing but within the cover of the box.
  • a locking screw 47 the rocker 36 can be rotated in several discrete positions, e.g.
  • a toothed segment 38 (FIG. 8) meshes with a toothed ring 51 held in a rotationally fixed manner on the shaft part 30. By rotating the shaft part 30, the toothed segment 38 is moved to the left or to the right for lowering and pulling up the store and is disengaged from the toothed ring 51 .
  • the pivoting device is locked by means of locking bolts 42, 43, which are pressed against the flanks of the toothed segment 38 by springs 41, and the band 14 can be unrolled or rolled up.
  • the mode of operation will be explained below in the description of the mode of operation.
  • the tape reel 33 is equipped with a wedge 39 which slides radially into its hub when the tape is wound up (Fig. 5), and when that Band 14 is completely unwound, protrudes from the hub into a locking position (Fig. 6).
  • a pawl 45 is rotatably mounted on the housing on a bolt 46. Due to its own weight, this pawl 45 rests on the belt 14 and comes to a stop at a locking surface 52 when the belt 14 is unwound. (Fig. 6)
  • Fig. 7 shows the winding phase.
  • the pawl 45 is accordingly lifted by the wound band 14 from the pawl stop 48 and half a turn further the wedge 34 is then pressed into the hub of the reel and the store can thus be lifted up.
  • the store is stacked in the lintel.
  • the cam 53 of the swivel plate 34 is locked in the catch 54 (FIG. 9).
  • the fixed cam 37 locks the locking bolt 42 so that the toothed segment 38 remains in position outside of the engagement with the ring gear 51.
  • the pawl 45 (FIG. 5) rests on the band 14 wound on the band reel 33 and slides on the band 14 during rotation.
  • the further rotation of the reel shaft 29 has the effect that the toothed segment 38 is further rotated counterclockwise by the ring gear 51 and the locking bolt 42 is thereby lifted off the control curve 37.
  • the toothed segment 38 is carried along until it is no longer in engagement with the ring gear 51. This causes the spring 41 to be tensioned and press the toothed segment 38 against the ring gear 51.
  • the swivel plate 34 is locked and uncoupled by the engagement of the cam 53 in the catch 49, the tape 14 is unrolled by the further winding of the reel 33 and the store lowers with the slats 49 opened by the set angle of the catch 49.
  • the band 14 releases the pawl 45, which thereby comes to rest and by which the wedge 44 is released so that it can be pressed outwards by the wedge spring 44a.
  • the wedge 44 engages in a groove in the swivel disk 34 and takes it with it. After a rotation of 180 °, the swivel disk 34 is locked by the pawl 45 and the store is in the closed position of the slats.
  • the hexagonal shaft 30 and thus the tape reel 33 are rotated clockwise.
  • the ring gear 51 takes the toothed segment 38 with it. This makes a counterclockwise rotation and abuts the locking bolt 43. Torque is thus transmitted to the swivel plate 34 via ring gear 51, toothed segment 38 and locking bolt 43. This now turns together with the reel 33 in a clockwise direction.
  • the cam 53 is thus pressed out of the detent and the locking bolt 43 slides on the control cam 37.
  • the locking bolt 42 thus relieved is pressed down by the spring 41 against the swivel plate 34 and the cam 53 engages in the detent 49 on the adjustment pocket 36c and the locking bolt 42 is released. In the meantime, the locking bolt 43 slides on the cam 37 and is held down.
  • the released locking bolt 42 is pushed upwards by the rotating swivel disk 34.
  • the toothed segment 38 continues to rotate counterclockwise until it no longer meshes with the ring gear 51. However, it is pressed against the ring gear 51 by its own weight. Because the swivel plate 34 is locked but uncoupled, the further winding of the reel 33 causes the band 14 to be wound up.
  • the wedge 44 is pressed inwards by the band 14 and by the groove in the swivel plate 34.
