Open the CIPO recordAbstract From the Canadian patent
Assembling a window frame with shutter channels mounted on it is facilitated by an indirect or direct mechanical connection of the shutter-housing base plate to the upper leg of the window frame by connectors on the front that extend over the area between the shutter channels at a distance, therefrom over the length of the upper leg of the frame. The screwless connection between the complete shutter housing and the window frame saves time and personnel.
