  • Patent number: 7530543
    Abstract: An apparatus includes a central support shaft that has an elongated shape provided with axially opposed ends. Rectilinear legs have opposed ends conjoined to the bottom support shaft end and extending outwardly therefrom at an oblique angle. The legs are pivotal between compressed and expanded positions. Auxiliary support shafts have elongated shapes provided with opposed medial and lateral ends. The auxiliary shafts are pivotally conjoined to the brackets and pivotal about the medial ends, such that the auxiliary shafts can be independently biased between vertical and horizontal positions. Brackets are attached to the central support shaft and spaced along a longitudinal length thereof. Clamps are positional along the auxiliary shafts. Each clamp is adaptable between open and closed positions for releasing and gripping the window blind. The window blind is centrally registered between the auxiliary support shafts during cleaning operations.
