Connector assembly for coplanar display panels

A connector assembly for releasably securing at least two panels in a coplanar relationship, each panel having a linear side edge, comprising:

• a first disk comprising a first disk body formed of a rigid non-deformable material, and a first elastomeric panel means on said first disk body having a first planar gripper surface adapted to seat against one major face of each of said panels;
• a second disk comprising a second disk body formed of a rigid, non-deformable material having a second planar gripper surface adapted to seat against another major face of each of said panels;
• said disk bodies having aligned central holes adapted to receive a clamping screw;
• at least one of said disk bodies having an integral spacer means projecting beyond the associated panel gripper surface, and comprising a raised annular wall surrounding said aligned central hole on said one disk body;
• at least one raised linear rib extending from said raised annular wall in a radial direction with respect to said central hole;
• said at least one raised linear rib having parallel sides extending at right angles to the planar gripper surface of the associated disk, said parallel sides being adapted to abut the linear opposed side edges of a pair of co-planar panels having spaced side edges that are to be secured by the connector assembly, on opposite sides of said linear rib;
• and
• a clamping screw means extending through said aligned holes for drawing said disks toward one another with the side edges of the panels sandwiched between said disks in abutment with the parallel sides of said linear ribs.
