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.

Claims

1. A louver rotation apparatus comprising:

an elongated member adapted for translatable engagement with a frame;

said member having a first surface, a second surface opposite said first surface, and a side surface communicating therebetween;

a plurality of gear modules, each said gear module having a geared surface in a cooperative engagement with a respective louver gear engaged with an individual louver in a plurality of louvers; and

means of attachment of each of said gear modules to said member at any individual attachment point along said member, each said attachment point registering said geared surface of said gear module in said cooperative engagement with a respective said louver gear, translation of said member, with said gear modules affixed at chosen said attachment points, imparting a rotation of all of said louver gears in a single direction thereby communicating a concurrent rotation in said direction to each said louver.

2. A louver rotation apparatus of claim 1 wherein said means of attachment of said gear module to said member at an attachment point comprises:

a plurality of opposing flexible clips projecting from each said gear module, said clips distanced to compressively engage said side surface of said member when positioned therebetween.

3. A louver rotation apparatus of claim 2 wherein said means of attachment of said plurality of said gear modules to said member at an attachment point further comprises:

a plurality of notches formed in the surface of said member, said notches positioned to engage with at least one flexible clip projecting from each of said gear modules; and

each of said plurality of notches when engaged with at least one of said flexible clips of a respective gear module thereby positioning that gear module at its respective attachment point.

4. The louver rotation apparatus of claim 1 wherein said means of attachment of said gear module to said member at an attachment point comprises:

a projection extending from one of each of said respective gear modules or respective member; and

each said projection dimensioned for cooperative fixed engagement with a respective aperture, said respective aperture formed on the other of each of said respective gear modules or said member.

5. The louver rotation apparatus of claim 1 wherein said means of attachment of said gear module to said member at said attachment point is adhesive.

6. The louver rotation apparatus of claim 1 additionally comprising:

a translation gear module engageable to said member at an engagement position;

means to translate said translation gear module thereby translating said member and rotating said louvers.

7. The louver rotation apparatus of claim 6 additionally comprising:

a worm gear rotationally engaged with said translation gear module substantially parallel to said member;

said means to translate said translation gear module being a means to rotate said worm gear; and

whereby rotation of said worm gear translates said worm gear module and said attached member thereby rotating any louvers having said louver gears engaged with said gear modules.

8. The louver rotation apparatus of claim 7 wherein said means to rotate said worm gear is a handle adapted for rotational communication with worm gear.

9. The louver rotation apparatus of claim 7 wherein said means to rotate said worm gear is an electric motor adapted for rotational communication with worm gear.
