Abstract: A collapsible modular display tower assembly has a three-dimensional, collapsible display panel structure having two opposing pairs of pivotally-connective links with upper and lower ends arranged to form four side faces when erect. A plurality of upper and lower hub assemblies are pivotally connecting the adjacent ends of the links of adjacent side faces. Four vertically-oriented expansible support and attachment braces are provided with each brace being connected to one pair of the vertically-aligned upper and lower hub assemblies. The braces permit the attachment of graphic representations and display accessories to the tower assembly. Releasable hub-connecting means in the form of male and female connectors are provided on the upper and lower hub assemblies for releasably interlocking a multiplicity of display panel structures into a vertical display tower.

Abstract: A pivotal frame connector or pivotal coupler for pivotally attaching two adjacent display structures wherein each of the display structures includes a skeletal frame formed of a network of elongate support rods joined by hub assemblies which provide for articulation of the support rods. The pivotal frame connector includes ends identical in structure to the ends of the support rods to engage those hub assemblies disposed on the periphery of the display frames. These peripheral hub assemblies have empty unused sockets to which the pivotal frame connector is readily attached. The pivotal frame connector is U-shaped and substantially shorter in length than each of the support rods to remain out of sight and out of the way when the display frame is covered by a skin-like aesthetic covering.

Abstract: The invention is a quick-release connector to be used with a collapsible display frame structure as taught in U.S. Pat. No. 4,658,560. The invention permits quick coupling and release between a rear and front hub as taught in U.S. Pat. No. 4,627,210. During use, the quick-release connector provides a solid lock when mounted in a coupled position with a hub. The release of the connector from a coupled position occurs upon movement of a slidable sleeve. A spring maintains contact between the slidable sleeve and the connector collar during coupling. Engagement of the slidable sleeve separates the sleeve from the collar permitting the connector to be pulled free from the hub. A split housing couples the connector to the hub. A spring-loaded slidable sleeve maintains the split housing in a locked position. The rear end of the connector is releasably mounted to a hub of a collapsible display frame structure.
