Displaceable swivelling vertically slatted venetian blind - with socket and shaft section forming rotation axes and faces forming release clutch

摘要

The slatted venetian blind has vertically mounted slats which can be displaced sideways, and swung within limits together about their vertical longitudinal axis. Their top ends are fastened to a retainer on a rotation axle hung in a movably mounted guide carriage in a carrier rail. The carriages are pierced by a sliding shaft with a screw thread, slat displacement being effected by use of a threaded nut. The rotation axes of the slats consist of a socket and a shaft section (8) held in it. The second of the toothed rim wheels in the swivelling mechanism, in engagement with the first (24), is set on the outside of the top end section of the socket, formed integrally with it. The release clutch between the slats and toothed rim wheels is made up from two mutually engaging faces (14) of the socket or shaft section.
