Collapsible lampshade

Abstract

A lampshade includes a collapsible frame to which a flexible cover is attached. The frame includes an upper ring and a lower ring. A plurality of support bars are arranged between the upper and lower rings. Each support bar includes an upper section and a lower section hinged to each other. The upper section of the support bar has an end hinged to the upper ring. The lower section of the support bar has an end hinged to the lower ring. The hinge connections between the upper and lower sections of the support bar and between the support bar and the upper and lower rings allow the frame to collapse without separating the parts from each other. A channel member is partially fixed to the upper section of the support bar for partially receiving the lower section of the support bar. Dimples are defined in the lower section of the support for engaging with bosses formed on the channel member for maintaining the support bar in an extended condition.
