Abstract:
A shutter system for controlling entry of outside light into a building comprising:a) louver means for selectively regulating entry of the light into the building; b) wherein said louver means comprises a plurality of slats, each said slat comprising i) a pair of longitudinal edges, ii) at least one slat end portion, each said slat end portion having a transverse edge, iii) pivoting means for pivoting said slat between an on open and closed position, iv) wherein said pivoting means is located adjacent one of said pair of longitudinal edges; c) frame means for positionally supporting said louver means; d) wherein said frame means comprises i) at least one outside peripheral frame edge, ii) at least one inside peripheral frame edge, iii) a hollow middle area substantially equal in size to an area of light regulation by said slats of said louver means, iv) a first face lying substantially in a first plane, and v) a second face opposing said first face and lying substantially in a second plane substantially parallel to said first plane; e) locating means for locating said louver means so that i) at least one said transverse edge is adjacent said at least one inside peripheral frame edge of said frame means, and ii) no said longitudinal edges at said slat end portions extend beyond about said plane of said first face of said frame means when said plurality of slats are in the fully open position; and f) blocking means for blocking substantially all the entry of the light between said louver means and said frame means adjacent each said slat end portion adjacent said at least one inside peripheral frame edge; g) wherein said first face of said frame means comprises said blocking means; h) wherein said blocking means is fixedly attached along said at least one inside peripheral frame edge adjacent each of said slat end portions; and i) wherein said blocking means extends inwardly from said at least one inside peripheral frame edge toward said hollow middle area.
