Abstract:
1. A connector for rigidly engaging elongate structural members in a display structure, the connector configured to interconnect at least two elongate structural members end to end, each structural member having a pocket and a hole defined at one end thereof, the connector comprising: a body; a beam connection portion defined at a free end of the body; a cavity formed in the beam connection portion of the body, the cavity including a semi-cylindrical guide surface having a generally semi-circular cross sectional shape around a centerpoint; an opening defined in the body and being open to the cavity adjacent the semi-cylindrical guide surface, wherein the opening has an elliptical shape in which the difference between a major and a minor diameter thereof is an offset distance; an eccentric fastener rotatably disposed in the cavity, the eccentric fastener comprising: wherein at least one raceway is defined peripherally around at least a portion of the semi-cylindrical surface, and wherein the eccentric fastener further includes a leg having a ledge, the leg extending away from the fastener within the cavity, the ledge extending radially away from the leg and forming an inclined surface such that when the eccentric fastener is rotated, the inclined surface of the ledge engages a surface of the raceway and provides a biasing force tending to push the eccentric fastener towards the opening.
