Abstract: A collapsible lamp shade includes a pair of resiliently compressible channel-defining members projecting inwardly from the interior surface of the shade cover to engage the periphery of a shade frame in a channel having an opening which is wider than the frame thickness. A structurally independent arcuately biased wire is selectively threaded into a sleeve at the lower edge of the cover to rigidify and radially expand the lower edge. Expansion of the lower edge tends to contract the upper edge about the frame to effect a more positive engagement of the frame in the channel. Structural independency of the frame engagement and the threaded rigidifying wire permit simple assembly at each edge of the shade without dislodging assembled components at the other edge. In the preferred embodiment the upper edge channel is defined by a cloth strip secured to the interior surface of the cover and having two transversely spaced sleeves extending in respective annular paths. Each sleeve contains a resiliently compressible length of material, such as twine, defining respective ribs which are resiliently compressible during assembly.
