Motorised venitian blind assembly

摘要

The blind has a controllable tubular motor (44) housed inside a tubular shaft (32) and integrated with a console (14) in order to drive the shaft in rotation around the motor and a rotary axis of the shaft. Complementary guiding units constitute a coaxial sleeve (36), a threaded element (40), a threaded rod (42) and a cylindrical case (46). The guiding units simultaneously guide the shaft in rotation and in translation along its rotation axis in order to helically roll bands (50, 52) around the shaft by which the bands form non-superimposed identical long coils. An independent claim is also included for a mono-block assembly comprising a motorized slat blind.
