ABSTRACT:
In a shutter assembly, individual shutter blades are connected to ribs of an auxiliary frame by way of living-type hinges, so that the living-type hinges form the pivot axes of the shutter blades. Furthermore, an actuating rod is provided, which is also connected by way of living-type hinges to the shutter blades. The auxiliary frame with the shutter blades and the actuating rod are thus combined into one structural unit which can be manufactured in one single operation in a three-part mold. This arrangement enables the shutter assembly to be manufactured at low cost by the injection molding technique so that assembly operations become unnecessary.
