A damper providing varying damping force is provided. The damper may include a housing and a rotary member rotatably received the housing. The rotary member may rotate within the housing between defined end points of travel to define an angular range of travel of the rotary member. An outermost surface of the rotary member may be spaced inwardly from an inner surface of the housing defined between the end points of travel to define a gap between the outermost surface of the rotary member and the inner surface of the housing throughout the angular range of travel. The gap may vary in dimension depending on a rotational position of the rotary member to provide varying damping rates within the angular range of travel of the rotary member.

A shutter assembly comprising a shutter door, an inner frame and an outer frame, wherein the shutter door defines an aperture and includes two or more rotatable vanes, wherein the vanes have a first orientation in which they completely obscure the aperture and a second orientation in which they partially obscure the aperture; the shutter door is hingedly coupled to the inner frame; and the inner frame is secured to the outer frame.

The present invention is a gear driven louver shutter system, wherein each louver of the shutter system is attached to the end of a pinion at both its ends. The base of each pinion is engaged with two gear strips disposed within a frame member. The arrangement is provided such that when one louver is adjusted, all the louvers in the shutter system will move accordingly. The gear strip and pinion system eliminates the need for a tilt bar. In a preferred embodiment, louvers of the system engage with pin connectors or clips to attach to the pinions. The pin connectors or clips allow for the louvers to attach to the pinons without requiring a tool. In an embodiment, the louvers will have a S-shape profile, to allow for light to be completely blocked when the shutter system is closed.
