  • Motorized louver blind structure in a double glazed window unit and method of assembling the blind structure
    Patent number: 5600920
    Abstract: The window unit of the invention comprises four peripheral channel members linked with corner members to form a window frame. Two glass panels are spaced by this frame to form an inner chamber, the louver blind structure of the invention being located completely therein. The louver blind structure comprises a plurality of horizontal slats pivotally supported at both their extremities and each having an integral toothed wheel engaging a complementary rack on an actuator bar, the latter positioned adjacent to a side peripheral channel member and being free to move upwards or downwards along it. This upward or downward movement imparts a pivoting movement to the slats. The louver blind structure further comprises a support channel member supporting a reversible electrical motor having a driving shaft. This shaft has an eccentric stud which engages the actuator bar and must therefore be kept properly alined so as to resist radial forces exerted thereon.
