Abstract
A lampshade adapted to be interconvertible between an assembled configuration having a first volume and a knockdown configuration having a second, smaller volume comprises lampshade segments connected to rotational elements. Slotting means on preselected rotational elements position the connecting members to assume predetermined positions with respect to the common axis, where the rotational elements are locked in place. Methods for use of the lampshade in knockdown shipping, and kits containing the lampshade and instructional materials are also taught.
