<p>The slatted venetian blind has vertically mounted slats which are displaceable sideways and have a common limited swing about their vertical longitudinal axis. The slat top ends are connected to spindles suspended in guide carriages moving in a carrier rail. There are slip couplings between slats and their spur wheels. On the helically threaded displacement shaft, passing through the guide carriages in the carrier rail, at least one section is held to the bushing with a friction locking effect. This is pref. effected along the whole shaft length.</p> |
