Abstract

An louver rotation mechanism for use in rotating a louvered shutter having louvers rotationally engaged with a frame. The device features one or a plurality of gear modules which are positionable to a fixed location on one or a plurality of rack bars. The gear modules may be spaced on the rack bars to any number of positions wherein they will engage with louver gears from an array of louvers engaged with the frame. A high degree of customization is provided by allowing the use of the rack bars with any number of different sized louvers at different spacings in a frame by simply adjusting the positions of the rack modules for operative engagement with the louver gears. Translation of the rack bars is provided by aperture housed gear racks which are translated by an engaged gear.

an engagement gear adapted for operational engagement with said gear rack; and

means to rotate said engagement gear from outside said frame, whereby rotation of said engagement gear translates said member thereby rotating said louver.

10. The louver rotation apparatus of claim 4 additionally having:

an aperture formed through said member, said aperture having two sidewalls;

a gear rack formed on one of said sidewalls;

an engagement gear adapted for operational engagement with said gear rack; and

means to rotate said engagement gear from outside said frame, whereby rotation of said engagement gear translates said member thereby rotating all of said plurality of louvers concurrently.

11. The louver rotation apparatus of claim 1 additionally having:

a gear rack formed on a sidewall of said member;

an engagement gear adapted for operational engagement with said gear rack; and

means to rotate said engagement gear from outside said frame, whereby rotation of said engagement gear translates said member thereby rotating said louver.

12. The louver rotation apparatus of claim 2 additionally having:

a gear rack formed on a sidewall of said member;
