  • Publication number: 20070137798
    Abstract: A Venetian-style window blind (10) that resembles plantation style shutters is described. In a preferred embodiment, the headrail is shaped like the plurality of slats depending from it, is pivotally connected to the sides of a window frame by mounting brackets and has a hollow interior. Tilting of the plurality slats depending from the headrail is accomplished by vertically moving an actuator rod that is pivotally connected to the headrail. The plurality of slats are suspended from the headrail by a cord ladder to tilt in unison with the headrail. While tilting the blind assembly into the closed position, the headrail and depending slats also slide inwardly towards the windowpane. The slats are lifted through the actuation of a lift handle that is slidably attached to the actuator rod and contains therein a lock mechanism to hold the slats in a desired position.

  • Publication number: 20050126719
    Abstract: A magnetic catch is used on coverings for architectural openings to releasably retain the coverings in an extended position and immediately adjacent to the framework of the opening. Magnetic components are installed on the covering and the framework surrounding at least part of the architectural opening. The covering is then placed in a position such that the magnetic components on the covering and the framework are close enough to attract each other through their respective magnetic forces. The magnetic forces work to releasably hold the covering in position relative to the framework.
