Abstract
An arched shutter assembly is provided having generally V-shaped or tapered louvers operated by a uniformly arched operating arm all mounted within an arched peripheral frame. Each louver rotates on an axis that is aligned with a center reference point at the juncture of a central hub and radial frame members. The arched shutter assembly can be shaped to fit a variety of arched or circular windows and is commonly used to provide an operable shutter for an arched window above a rectangular door or window.
Claims12
An arched shutter assembly, comprising:
- a) a peripheral frame, including
- 1) a plurality of radial members, and
- 2) an arched rim having an inner arched edge that includes a series of evenly spaced rim apertures;
- b) an interior hub block seated at a juncture of two of the radial members, including an outer arched edge having a series of evenly spaced hub apertures;
- c) a plurality of louvers mounted within the frame, each louver including
- 1) an interior end having a hub pivot bushing seated in one of the hub apertures,
- 2) two diverging radial edges,
- 3) an exterior end having a rim pivot bushing seated in a corresponding rim aperture,
- 4) a rotating axis extending through the rim pivot bushing, through the louver, and through the hub pivot bushing, the rotating axes of all the louvers intersecting a center reference point, and
- 5) a connector embedded in one of the radial edges a selected distance from the exterior end, the connectors in adjacent louvers each being spaced an equal distance from the center reference point;
- and
- d) a uniformly arched operating arm having a plurality of evenly spaced eyelets connected to the connectors in the louvers such that the operating arm occupies a uniform arc, equidistant along its length from the center reference point.

An arched shutter assembly, comprising:
- a) a peripheral frame including a plurality of radial members and an arched rim;
- b) an interior hub block seated at a juncture of two radial members;
- c) a plurality of louvers, each louver pivotally mounted to the frame between the interior hub block and the arched rim, each louver having a rotating axis that intersects a center reference point when extended inwardly;
- and
- d) a uniformly arched operating arm operably attached to each louver, the operating arm disposed in a uniform arc of a generally constant radius from the center reference point, the radius being shorter than the radial members.
