Electrostatically positioned blind insert for insulated glass
First Claim
1. An electrostatically controlled blind system comprising:
- a plurality of elongated, electroconductive louvers each having a longitudinal axis, each of said louvers having a plurality of apertures formed therein at predetermined locations, said louvers further including pivoting means installed thereon in generally parallel relation to said longitudinal axis at a predetermined offset position in relation thereto;
a plurality of vertically disposed louver supporting means installed within said apertures and being disposed in pivoting engagement with said pivoting means such that said louvers are horizontally arranged in parallel, spaced apart relation, said louvers being supported in an unbalanced condition and biased downwardly about said axis to a closed condition due to gravitational force;
at least one sheet of electroconductive glass positioned in a plane parallel to a plane defined by said longitudinal axes of said louvers and in close proximity thereto, said glass being disposed in electrical connection to said louvers and being electrically grounded; and
a variable electrostatic power source being electrically connected to said louvers such that when an electrostatic charge is applied to said louvers, an opposite electrostatic charge is induced on said glass creating an electrostatic force of attraction between said louvers and said glass enabling said louvers to be rotatably positioned about said axis to an open condition whereby the passage of light therethrough can be regulated.

Abstract
An electrostatically controlled blind system for use in limiting the passage of light through windows, doors, and skylights in building structures is disclosed. The blind system comprises a plurality of elongated, electroconductive louvers which are pivotally supported within an electroconductive peripheral frame. The blind system is inserted between sheets of insulated glass having an electroconductive coating and is thereby insulated from the ambient atmosphere. A voltage converter converts alternating current to an electrostatic charge which is distributed on the surface of the louvers causing them to repel each other. The electrostatic charge on the louvers induces an opposite electrostatic charge on the grounded sheets of insulated glass creating an electrostatic force of attraction therebetween. The combined electrostatic force of repulsion between the louvers and the electrostatic force of attraction between the louvers and the insulated glass permit variable adjustment and remote control of the blind system.

8. An electrostatically controlled blind system comprising:
-
a plurality of elongated, electroconductive louvers each having a longitudinal axis, said louvers being oriented vertically in parallel, spaced apart relation; a plurality of louver supporting means including suspension wire means being attached at an upper end of each respective louver, said louver supporting means further including a pivot post means attached to a lower end of said louvers such that said louvers are imparted with rotational movement about said longitudinal axes; at least one sheet of electroconductive glass positioned in a plane parallel to a plane defined by said longitudinal axes of said louvers and in close proximity thereto, said glass being disposed in electrical connection with said louvers and being electrically grounded; and a variable electrostatic power source being electrically connected to said louvers such that when an electrostatic charge is applied thereto, an opposite electrostatic charge is induced on said glass creating an electrostatic force of attraction between louvers and said glass enabling said louvers to be rotatably positioned about said axis whereby the passage of light therethrough can be regulated.
