An automated louvre system

摘要

A motorised drive system for a louvre assembly is disclosed. The louvre assembly includes a surround frame and a pair of spaced apart operating bars positioned within the surround frame where movement of the operating bars causes rotation of the louvres. The drive system comprises a motor (10) adapted to be positioned within the surround frame which operationally drives a drive shaft (22) which is substantially horizontal when the drive system is fitted within the surround frame, a mounting member (12) which is attached for rotation with the drive shaft, at least two spaced apart attachment points (23) on the mounting member, a first link arm (13) attached to one of the attachment points and to one said operating bar (18), a second link arm (15) attached to another of the attachment points and a third link arm (16) pivotally attached to the second link arm (15) and to the other operating bar (19).
