Patent

CA 2594107

A louver blade positioning device of a motorized shutter assembly includes an indented positioning portion or a protruded portion formed upon a driving shaft and a resilient member coming into contact with the driving shaft and the indented positioning portion or the protruded portion in a radically movable manner at a fixed angle. When the louver blades are rotated to approach a specific angle, the resilient member moves into the indented positioning portion or the protruded portion. Through the resilient force exerted by the resilient member on the indented positioning portion or the protruded portion, the driving shaft rotates to approach the specific angle, such that the louver blades become positioned at the specific angle when being rotated to approach the specific angle, thereby becoming free from the angular clearance inherent among transmission components of the motorized shutter assembly.
