  • the coupling device 12 can be transferred to the locking setting by rotating the cam 32 about an axis of rotation 33 which corresponds to its longitudinal central axis (and runs perpendicular to the plane of the drawing), which is shown in FIG figure 14 is shown.
  • the traction means 4 is pinched between the coupler housing 23 and the cam 32, while in the release setting, shown in FIG figure 13 shown is not pinched between coupler housing 23 and cam 32 .
  • FIG 15 shows an exploded view of a partial section of the lower end of a further exemplary embodiment of a venetian blind according to the invention.
  • the external venetian blind has a bottom rail 8 with a cover part 16 and a base part 15 .
  • the base part 15 can be closed with the cover part 16 by a snap-in connection.
  • the cover part 16 has an opening 7 for the traction mechanism 4 .
  • Two coupling devices 12 (only one of which is shown in FIG. 1) are arranged in the bottom rail, each of which connects one of the traction means 4 to the bottom rail 8 .
  • the maximum output length 13 of the traction device 4 from the drive device 1 to the bottom rail 8 and the maximum distance 14 between the bottom rail 8 and the drive device 1 in the vertical plane of the traction device 4 can be adjusted by means of the coupling device 12, in particular steplessly.
  • the base part 15 Arranged on the base part 15 are two counter-fastening elements 18 designed as strips, each of which has a bend 19 along its free end. The bends 19 are aligned opposite to each other.
  • the coupling device 12 has fastening elements 20 with receptacles 21 for the bends 19 of the counter-fastening elements 18 .
  • the coupling device 12, when connected to the Base part is connected, are moved linearly along the counter-fastening elements 18 designed as strips relative to the base part 15 .
  • the coupling device 12 has a housing 23, which in particular figure 20 can be seen in detail.
  • the housing 23 has two openings 22 for the traction mechanism 4 .
  • the fastening elements 20 are formed with the receptacles 21 for the angled portions 19 of the counter-fastening elements 18 in the housing 23 .
  • the housing 23 has a fixing element receptacle 34 for a fixing element 44, which in particular figure 21 is shown in detail.
  • the fixing element 44 has two relatively movable coupling device elements 25, namely two clamping arms 36 on.
  • the clamping arms 36 are each connected to a handle section 38 by means of an elastic hinge 37 .
  • the fixing element 44 is produced in one piece, preferably as an injection molded part. However, it is entirely possible to produce the fixing element 44 in a different way, in particular from a number of separate components.
  • There is a slot 39 between the clamping arms 36 the slot width of which is reduced for clamping the traction means when the fixing element 44 is inserted into the fixing element receptacle 34 of the housing 23.
  • the clamping arms 36 each have a latching lug 40 which engages behind a latching edge 41 of the housing 23 when the fixing element 44 is inserted into the fixing element receptacle 34 of the housing 23 .
  • the housing 23 has a bolt receptacle 35 for a bolt 43 around which the traction means 4 is placed.
  • the traction means 4 runs through the openings 22 to the bolt 43 around which it is placed and the free end of the traction means 4 runs through the openings 22 back out of the coupling device 12 .
  • the traction means 4 is threaded through the openings 22 into the housing 23 and back out of the housing, preferably in such a way that the resulting loop initially protrudes from the housing 23 . Then the bolt 43 is inserted into the bolt receptacle 35 .
  • the bolt receptacle 35 has (according to an independent inventive idea) a bolt receptacle opening 42 pointing downwards, which allows the loop of the traction means 4 to be pulled tight until the traction means 4 grips the bolt 43 inserted into the bolt receptacle 35 and rests against the bolt 34.
  • the traction means 4 has to be laboriously threaded around the bolt 43 within the housing 23 or that the bolt 43 has to be laboriously inserted into a tiny loop of the traction means 4 within the housing 43 .
  • the openings 22 and the bolt receiving opening 42 are preferably arranged in a common plane.
  • the traction means 4 runs through the openings 22 into the housing 23 and is placed tightly around the bolt 43, with the free end of the traction means 4 running out of the housing 23 again.
  • the maximum output length of the traction device 4 from the (in the Figures 15 to 21 not shown) Drive device 1 to sub-note 8 can be adjusted by pulling part of the traction device 4 further through the coupling device 12 and extending the protruding free end of the traction device 4 if the maximum output length 13 is to be shortened, and that a Part of the traction device 4 is pulled back in the opposite direction by the coupling device 12 and the protruding free end of the traction device 4 is shortened if the maximum output length 13 is to be extended.
  • a frictional resistance can be generated in a very particularly advantageous manner in that the fixing element 44 is only partially inserted into the fixing element receptacle 34 of the housing 23 for the adjustment process.
  • the traction means 4 can be moved through the coupling device 12 against an adjustable resistance (by selecting the depth of insertion of the clamping wedge 28 into the fixing element receptacle 34) or into the coupling device, with the resistance preferably being selected in such a way that it is just sufficient for the Keep lower rail 8 hanging on the traction device 4.
  • This has the very particular advantage that until the final setting is reached, the setting that has just been made can be continuously checked (and corrected if necessary) without the risk of accidentally destroying the setting that has just been made.
  • the coupling device 12 is designed in such a way that a set relative position of the traction mechanism relative to the coupling device 12 and relative to the lower rail 8 does not change as a result of the switching process from the release setting to the fixed setting, i.e. due to the complete insertion of the clamping wedge 28
