ABSTRACT:
A ready-to-assemble knock-down kit for forming a lamp shade and analogous articles includes a plurality of panels, preferably of flexible non-self-supporting material such as cloth, and a plurality of longitudinally-extending ribs for snappingly engaging adjacent side edge regions of each two adjacent panels. Each rib has resilient wall portions which bound a generally U-shaped channel for receiving therein with snap-type action a side edge region of one panel and a side edge region of another adjacent panel. The panels are supported in a predetermined lamp shade type orientation relative to each other by a plurality of support elements which extend radially outwardly from a ring member that is adapted to be mounted on a lamp to be shaded. Each support element has one end turnably mounted in the ring member and another end mountable on a respective rib. The other end is receivable either directly in the channel of the respective rib or in an auxiliary channel formed in an extension of the rib. The shade is assembled from a plurality of parts which are shipped in a generally flat, compact or collapsed condition.
