Definitions

  • the present invention relates to a roman blinds according to the preamble of claim 1.
  • a store of the type mentioned is described for example in DE-PS 26 42 655.
  • the tension of the elevator belt is used in each case for the actuation of the release means, which release means release the pivoting device.
  • This presupposes that an elevator belt must be assigned to each pair of carrier or luffing belts.
  • the present invention therefore has as its object to improve a store of the type mentioned in such a way that there are no openings in the slats without having to forego the convenience of the half-open slats when the store is being lowered.
  • a sleeve 2 is rotatably attached on the section of a winding shaft 1 shown. This is rotatably mounted in a housing, not shown.
  • a gear 3 On the sleeve 2 there is a gear 3, while a cam plate 4 is mounted on the sleeve end closer to FIGS. 1 and 2 so that it can rotate freely.
  • a second gear 3 ' Between the gear 3 and the cam 4, a second gear 3 'is freely rotatable.
  • the number of teeth of the gear 3 ' is, as described later, less than that of the gear 3.
  • the cam 4 has a recess 5 which extends over 180 ° and which forms a clutch with a spring 6 arranged in a longitudinal slot 32 of the sleeve 2.
  • the first gear 3 (35 teeth) rotates through 360 °
  • the second gear 3 '(34 teeth) rotates one tooth further than 360 °.
  • the first gear 3 has a recess 8 into which the spring 6 can pivot when it is relaxed.
  • the second gear 3 ' has a recess 11 serving the same purpose. This recess 11 is provided with inclined lateral flanks, the inclination of which is selected such that the spring 6 is pressed against the sleeve 2 by advancing the second gear 3 'during half a revolution of the first gear 3 and thus disengaged from the cam plate 4 becomes.
  • a further sleeve 12 is pivotally mounted with two parallel cross members 9.
  • the cross members 9 are penetrated at the ends by pins 10.
  • the sleeve 12, the crossmember 9 and the pins 10 form a swivel device, the slats 25 of the store being suspended on the pins 10 by means of pairs 11 of support members.
  • the sleeve 12 is also firmly connected to a clutch housing 13.
  • One wall of this housing is designed as a circular disk 14 with two cams 15 and 16.
  • Axis 17 are pivotably mounted on a first and a second pawl 18 and 19, respectively.
  • the two pawls 18 and 19 are each assigned to a first ratchet wheel 20 and a second ratchet wheel 21, which are seated on the sleeve 12 in a rotationally fixed manner. If the winding shaft 1 rotates in one direction, the first ratchet wheel 20 takes the first pawl 18 with it and pivots the pivoting device 9, 10, 12. If the winding shaft 1 rotates in the other direction, the second ratchet wheel 21 takes the second pawl 19 with it and pivots it Swivel device in the other direction.
  • a stop 22 with two stop surfaces 23, 24 is provided in a stationary manner. If the winding shaft 1 (FIG. 6) rotates counterclockwise to lift the store, the second ratchet wheel 21 takes the second ratchet 19 with it until it hits the stop surface 23 and disengages.
  • the pivoting device 9, 10 and 12 is pivoted so far that the slats 25 are horizontal, i.e. take an open position.
  • a resilient web 26 connected to the stop 22 has a recess into which the cam 15 engages in the lamella position shown in FIG. 6. The pivoting device 9, 10 12 is thereby held in this position during the lifting of the store.
  • the first ratchet wheel 20 takes the first ratchet 18 with it and pivots the pivoting device 9, 12, 10 to the other side.
  • a movable stop 27 with a recess 28 (FIGS. 2 and 6) is provided which engages in the pivoting path of the first pawl 18 and disengages it when it hits it.
  • the stop 27 is non-rotatably mounted on a pivot shaft 29 which further carries a control cam 30.
  • a spring 31 acting on the stop 27 holds this in contact with the circular disc 14.
  • the stop 27 engages in the displacement of the first pawl 18 during the lowering of the store and disengages it until the store is lowered.
  • the cam 16 is locked in the recess 28 of the stop 27 and thus prevents the slats from pivoting due to gusts of wind.
  • the cam disc 4 If the cam disc 4 is connected in a rotationally fixed manner to the winding shaft 1 by the spring 6, which takes place approximately half a revolution of the winding shaft 1 before the store is completely lowered, then it pivots the stop 27 out of the displacement path. Then the pawl 18 couples into the ratchet wheel 20 and pivots the pivoting device 9, 10 12 further until the first pawl 18 hits the stop surface 24 and is disengaged. In this position of the swivel device 9, 10, 12, the slats 25 are closed (FIG. 8). In the closed lamella position, the cam 16 is locked in the recess of the web 26. If the lowered store is to be raised, the wind-up shaft is rotated counterclockwise as described (Fig. 6).
  • the second ratchet wheel 21 takes the second ratchet 19 with it and pivots the pivoting device 9, 10, 12 until the second ratchet 19 hits the stop surface 23 and disengages.
  • the cam 15 engages in the recess of the web 26. Until the slats are completely gathered, they remain in their horizontal, open position and are held in this position by the cams 15 which are locked in the web 26.
  • the cam disc 4 is also rotated back during part of the first rotation of the winding shaft 1 until the trailing flank of the slot 11 presses the spring 6 into the slot 32 again. With the turning of the cam disc 4, the stop 27 is pivoted back into the displacement path of the first pawl.
  • the latching device (16, 26) prevents the crossmember 9 from pivoting clockwise beyond the closed position of the slats 25 shown in FIGS. 4 and 8 when the store is lowered.
  • the slats 25 can be pivoted as desired between the fully open position (FIG. 6) and the completely closed position (FIG. 8).
  • any number of sleeves 2 suitable for supporting the slats are arranged between the slat ends on the winding shaft 1, viewed in the vertical direction, the elements described being arranged on each sleeve 2.
