Abstract
A shutter assembly includes a base plate defining a shutter opening having a central axis, and a drive assembly coupled to the base plate. The drive assembly includes a rotatable pinion gear, and a drive rack mating with the pinion gear and moveable in a substantially linear direction in response to rotation of the pinion gear. The shutter assembly also includes a plurality of shutter blades operably connected to the drive rack. The plurality of shutter blades are configured to rotate between an open position exposing the shutter opening and a closed position substantially occluding the shutter opening in response to movement of the drive rack in the substantially linear direction.
