Abstract
An apparatus for a pop-up display structure that provides a hub structure that is divided into two sections that are held together by a thumbscrew. The two sections define internal channels in the hub for capturing guide pins attached to the tubes such that the tubes pivot about the guide pins and rotate about the hub through slots in the hub. The thumbscrew provides for removal of tubes from the hub structure without the use of tools and therefore provides for changes on the fly for reconfiguring the structure or for replacing broken tubes. The thumbscrew also provides a mounting structure for the channel bar that attaches to the pop-up structure. The channel bar is capable of folding into three sections and is capable of folding compactly without regard to the sequence of the folds.
