Roller blind drive mechanism - has bottom-mounted single electric motor for two=way control

摘要

The roller blind (3) is closed by a cord (24) pulley (35, 37) connected to sheave (21) mounted at the end of the blind roller (24). The roller is driven by an integral electric motor (10). Through an arrangement of a friction drive and a free running coupling, the single reversible motor is able to both open and close the blind. USE/ADVANTAGE - Roller blind closure system. Requires only single motor.
